As used in the Transaction Agreement and for purposes of this proxy statement, "Acquired Business" means the business conducted by us and our subsidiaries, excluding the insurance business of NLASCO, Inc., or NLASCO, and related insurance activities, but including owning and operating our manufactured home communities, as well as providing related financing services and businesses related thereto; and "Acquired Companies" means ARC Real Estate, LLC, ARCAL LLC, ARC Real Estate Holdings, LLC and Enspire Finance LLC, and each of their respective subsidiaries that are treated as pass-through entities for U. S. federal income tax purposes.

Description of the Assets to be Sold (page 43)

We have agreed to sell to Buyer all of our and our subsidiaries' assets primarily relating to the manufactured home communities business, including the owning and operating of manufactured home communities, the provision of related financing services, and business related thereto, but excluding the insurance business of NLASCO and related insurance activities. Pursuant to the Transaction Agreement:

•

cash in an amount equal to the sum of the following:

Other than the liabilities described below under "Description of Liabilities to be Retained by ARC", in connection with the purchase of the assets Buyer agrees to assume liabilities of the Sellers to the extent related to the Acquired Business, our equity interests in the Acquired Companies and the Acquired Assets, including:

•: certain specified indebtedness existing as of the date of the Transaction Agreement, and indebtedness incurred in the ordinary course of business and in accordance with the Transaction Agreement between the date thereof and the closing of the transaction, but excluding liability for defaults or breaches of any material covenants occurring prior to closing and excluding

indebtedness relating to the aircraft included in the Acquired Assets (we refer to this indebtedness as "Assumed Indebtedness");

•: all liabilities with respect to all pending, threatened or other actions, suits, proceedings, investigations or other claims to the extent relating to or arising from the Acquired Business or the Acquired Assets, or any asset in the Acquired Business;
•: all liabilities to the extent relating to or arising from the ownership, operation, possession or management of the Acquired Business or the Acquired Assets, or any asset in the Acquired Business, including accounts payable and trade obligations;
•: all liabilities under or in connection with any contracts included in the Acquired Assets;

•: all other liabilities to the extent resulting from, arising out of or relating to the Acquired Business, the Acquired Assets or any asset in the Acquired Business; and
•: the obligation to pay certain "stay bonuses" to certain of our employees.

Description of the Assets to be Retained by ARC (page 44)

We will retain all assets not sold to Buyer, including the Retained Business. We will also retain certain assets that may relate to the Acquired Business. These include cash and cash equivalents (with certain exceptions), equity interests in any Seller, all of our assets related solely to the Retained Business, our rights, claims and interests under the Transaction Agreement or any other transaction document, and all of our intangible property primarily related to the Retained Business, including the "Enspire" and "NLASCO" trademarks. In addition, we will retain certain assets related to previously sold communities and certain deferred assets.

Description of Liabilities to be Retained by ARC (page 45)

We will retain all liabilities not assumed by Buyer, including liabilities relating to:

•: the Retained Business;
•: any assets retained by Sellers (which we refer to as the "Excluded Assets");
•: our indebtedness or the indebtedness of any of our subsidiaries (including any Acquired Company), other than Assumed Indebtedness, including liabilities related to breaches of material covenants and indebtedness related to our aircraft;
•: any equity interest in us or our subsidiaries (other than the equity interests in the Acquired Companies) and related liabilities and obligations (including fiduciary obligations of our board of directors);
•: liabilities relating to taxes for any period ending on or before the closing date;

•: liabilities of Sellers under the Transaction Agreement or any other transaction document;
•: any liability for which Buyer and certain of its affiliates are indemnified pursuant to the Transaction Agreement, to the extent so indemnified; and
•: acts or omissions of us or our subsidiaries (excluding the Acquired Companies) after the effective time of the transaction.

Prior to the closing of the transaction, we or our designated affiliates will assume, pay, discharge and perform all of the above liabilities retained by us. In addition, the Sellers have assumed financial responsibility for the following expenses: costs of obtaining title policies and certain endorsements related to the acquired properties, costs of a survey for each acquired property, all costs related to debt and preferred stock retained by Sellers, all costs related to the unitholders of ARC LP, and all other costs incurred in connection with obtaining our or the other Sellers' required statutory approvals and other consents.

Purchase Price (page 45)

Upon consummation of the asset sale, we will receive cash in the amount of the excess of $1.794 billion over the amount of Assumed Indebtedness as of the closing of the transaction, as such amount is adjusted as described under "The Transaction Agreement—Purchase Price Adjustments".

Use of Proceeds (page 26)

Under the terms of the Transaction Agreement and after giving effect to estimated expenses and taxes, the amount realized by us is estimated to be approximately $540 million to $550 million net of retained debt and preferred stock as more fully described in Annex D, Selected ARC Historical Financial Data and Unaudited Proforma Condensed Consolidated Financial Statements—Unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2007, note (a). We will use a portion of the proceeds for general working capital and to repay outstanding obligations. In addition, we currently anticipate seeking to make opportunistic acquisitions with certain of the proceeds. We do not intend to distribute any of the proceeds that we receive from the asset sale to our stockholders. Rather, we intend to use any proceeds from the transaction, along with our existing cash and cash equivalents, in connection with our future business plans.

Reasons for the Asset Sale (page 28)

We are proposing to sell all of our and our subsidiaries' assets primarily relating to the manufactured home communities business, including the owning and operating of manufactured home communities, the provision of related financing services, and business related thereto, but excluding the insurance business of NLASCO and related insurance activities, because we believe that the asset sale and the terms of the Transaction Agreement are in our best interest and in the best interest of our stockholders. In reaching its determination to approve the asset sale, the Transaction Agreement and related agreements, our board of directors consulted with senior management and our financial and legal advisors and considered a number of factors, including the opportunities and challenges facing us, the fairness opinion delivered by our financial advisor and the terms of the Transaction Agreement.

Recommendation of Our Board of Directors (page 29)

After careful consideration, our board recommends that you vote "FOR" (i) the proposal to approve the asset sale pursuant to the Transaction Agreement, and (ii) the proposal to approve any

motion to adjourn or postpone the special meeting to a later date to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the foregoing proposal.

Opinion of Our Financial Advisor (page 29)

Our board of directors retained Sandler O'Neill & Partners, L.P., or Sandler O'Neill, to act as its financial advisor in connection with a possible business combination with a second party. As part of the engagement, Sandler O'Neill was asked to render a fairness opinion as to whether the consideration we are to receive from Buyer in connection with the asset sale is fair, from a financial point of view, to us. Sandler O'Neill delivered an opinion, attached as Annex C to this proxy statement, to our board of directors to the effect that, as of April 17, 2007, and subject to and based on the considerations referred to in its opinion, the consideration to be provided in connection with the asset sale is fair, from a financial point of view, to us.

Vote Required to Approve the Proposals (page 38)

The asset sale cannot be completed unless, among other things, it is approved by the affirmative vote of holders of shares of our common stock and special voting stock entitled to cast at least a majority of all votes entitled to be cast on the matter at our special meeting, voting as a single class. The proposal to approve any motion to adjourn or postpone the special meeting requires the affirmative vote of a majority of the votes cast by the holders of common stock and special voting stock. Only holders of our common stock and special voting stock of record at the close of business on , 2007, the record date for the special meeting, may vote at the special meeting and any adjournments or postponements of the special meeting. If we fail to obtain the requisite vote for the proposed asset sale, we will not be able to consummate the asset sale and either party may terminate the Transaction Agreement.

Each of Gerald J. Ford, ARC Diamond, LP and Hunter's Glen/Ford, Ltd., who as of April 17, 2007 collectively beneficially owned an aggregate of 9,421,642 shares of voting securities, representing approximately 16.0% of the votes entitled to be cast at the special meeting, entered into a Support Agreement, a copy of which is included as Annex B to this proxy statement. Pursuant to such Support Agreement, each such person agreed to vote, or cause to be voted, all of the shares owned by such person in favor of the transaction and other proposals described in this proxy statement and against any alternative transaction. Also, Farallon has informed us that certain of its affiliates intend to vote their shares of our voting securities, representing approximately 9.6% of the votes entitled to be cast at the special meeting, in favor of the transaction and other proposals relating thereto.

Covenants (page 50)

Under the Transaction Agreement, the parties agreed to covenants with respect to our conducting of business, obtaining necessary regulatory approvals, using commercially reasonable efforts, access to information, non-solicitation, and other customary covenants.

Employee Matters (page 58)

Under the Transaction Agreement, Buyer will offer employment to all ARC employees and Buyer's offer will include (i) a rate of base salary or wages equal to at least 100% of the rate of base salary or wages in effect immediately prior to the closing of the transaction and (ii) amounts of cash incentive opportunities that are no less favorable than those in effect immediately prior to the closing of the transaction. Buyer will offer employee benefits that are substantially similar in the aggregate to those provided immediately prior to the closing of the transaction.

We and the other Sellers remain solely liable (including with respect to severance costs and related liabilities) for any company employee who does not accept Buyer's offer of employment. Pursuant to

the Transaction Agreement and under certain circumstances, we may award "stay bonuses" of up to an aggregate of $4 million to help retain our employees, which bonuses will be paid (i) 100% by Buyer in the event they relate to our employees who are employed at properties that are marketed by the Buyer in accordance with the Transaction Agreement, or (ii) 50% by Buyer and 50% by us to the extent paid to any other of our employees.

Tax Matters (page 59)

Sellers will assume liability for and will pay all sales, transfer, stamp and similar taxes imposed on the sale of the Acquired Companies and Acquired Assets. Sellers have agreed to indemnify Buyer against all pre-closing taxes, and also against taxes arising from the transaction (including transfer taxes and taxes on gains of the Sellers).

Conditions to Completion of the Asset Sale (page 60)

The parties' obligations to consummate the asset sale are subject to satisfaction or waiver of a number of mutual closing conditions, including:

•: the absence of any injunction or order which prohibits the consummation of the transaction contemplated by the Transaction Agreement;

•: the receipt of required statutory approvals;

•: the receipt of our stockholder approval.

•: the performance in all material respects by Sellers and the Acquired Companies of their respective agreements and covenants under the Transaction Agreement;
•: the accuracy of our representations and warranties as of April 17, 2007 and the time at which the asset sale occurs, or the "effective time", other than those failures to be so accurate (disregarding all materiality or material adverse effect qualifiers in such representations and warranties), in the aggregate, that have not had or will not reasonably be expected to have a material adverse effect on the Sellers or a company material adverse effect;
•: the absence of any material adverse effect with respect to the Acquired Companies and the Acquired Business;
•: the delivery to Buyer of Sellers' officer's certificate certifying that the above conditions have been met;
•: the receipt of all required filings, permits, authorizations, consents and approvals with respect to Buyer;
•: the delivery to Buyer of title policies, surveys and related materials;
•: no company material adverse effect shall have occurred or be continuing; and

•: the performance in all material respects by Buyer of its agreements and covenants under the Transaction Agreement;
•: the accuracy of Buyer's representations and warranties as of April 17, 2007 and the effective time, other than those failures to be so accurate, in the aggregate, that have not had or would not reasonably be expected to have a material adverse effect on the Buyer's ability to consummate the transactions contemplated by the Transaction Agreement; and
•: the delivery of Buyer's officer's certificate certifying that the above conditions have been met.

Termination of the Transaction Agreement (page 61)

The Transaction Agreement may be terminated under certain circumstances, including:

•: by mutual written consent of us and Buyer;
•: by us or Buyer if the effective time has not occurred on or before December 31, 2007, (which we refer to as the "end date"), provided that the party seeking to terminate did not breach its obligations under the Transaction Agreement causing the failure to consummate the transaction before the end date;
•: by us or Buyer if an injunction, other legal restraint or order will have been entered permanently restraining or prohibiting the consummation of the transaction and such injunction or other order becomes final and non-appealable provided that the terminating party's breach did not cause such injunction, restraint or order;
•: by us or Buyer if we have our stockholder meeting and stockholder approval contemplated by the Transaction Agreement is not obtained;
•: by us if Buyer breaches or fails to perform any of its representations, warranties, covenants or other agreements contained in the Transaction Agreement and such breach or failure to perform (i) would result in a failure by Buyer of the conditions to the obligation of the Sellers relating to the performance of its obligations under the Transaction Agreement and to the accuracy of its representations and warranties, and (ii) is not curable or, if curable, is not cured prior to the earlier of 30 days after written notice of such breach is given by us to Buyer or one business day prior to the end date, provided that Sellers are not then in breach of the Transaction Agreement such that the conditions relating to the Sellers' performance of their obligations under the Transaction Agreement and to the accuracy of their representations and warranties would not be capable of being satisfied prior to the end date;
•: by us if all mutual conditions and Buyer's conditions to the Transaction Agreement are satisfied (other than conditions, the failure of which caused Buyer's breach, and conditions that, by their nature, were to be satisfied at closing and were capable of being satisfied at the time of termination) and Buyer fails to consummate the closing of the transaction within five business days after written notice by us of the satisfaction of closing conditions;
•: by us if prior to the receipt of our stockholder approval, our board of directors has received and approved a superior proposal and we concurrently enter into a definitive agreement relating to such superior proposal, provided that we have complied with the no solicitation covenant in the Transaction Agreement and have paid the termination fee and expenses of Buyer pursuant to the terms of the Transaction Agreement (as described below);
•: by Buyer if any of the Sellers have breached or failed to perform any of their representations, warranties, covenants or other agreements contained in the Transaction Agreement and such

breach or failure to perform (i) would result in a failure by Sellers of the conditions to the obligation of the Buyer relating to the performance of its obligations under the Transaction Agreement and to the accuracy of their representations and warranties and (ii) is not curable or, if curable, is not cured prior to the earlier of 30 days after written notice thereof is given by Buyer to us or one business day prior to the end date, provided that Buyer is not then in breach of the Transaction Agreement such that any of the conditions to the obligation of the Sellers relating to the Buyer's performance of its obligations under the Transaction Agreement and to the accuracy of its representations and warranties would not be capable of being satisfied prior to the end date;

•: by Buyer prior to the receipt of our stockholder approval, if (i) our board of directors makes a change in recommendation (as described under "The Transaction Agreement—Covenants—No Solicitation") or (ii) there is a material breach of the no solicitation covenant; or
•: by Buyer if, since April 17, 2007, there shall have been a company material adverse effect that is continuing and cannot be cured by the end date.

Termination Fees; Expense Reimbursement (page 62)

Termination fees will be paid under the following circumstances:

•: if the Transaction Agreement is terminated (i) by us because we have received and approved a superior proposal (as described above under "—Termination of the Transaction Agreement"), or (ii) by Buyer because our board of directors has made a change in recommendation or there is a material breach of the no solicitation covenant or, following a change in recommendation, pursuant to any other right of termination listed above, then in any such event we will pay to Buyer a termination fee of $20 million in cash plus an amount equal to all of the fees and expenses of Buyer, its contemplated transaction partners and its and their representatives, including fees and expenses of financial advisors, outside legal counsel, accountants, experts and consultants, incurred by Buyer, its contemplated transaction partners and its and their representatives in connection with the Transaction Agreement, up to a maximum of $5 million (which we refer to as the "Buyer Expenses");
•: if (i) an alternative proposal that reasonably appears to be a bona fide proposal is made known to us or directly to our stockholders or any person shall have publicly announced an intention (whether or not conditional or withdrawn) to make an alternative proposal that reasonably appears to be bona fide and thereafter (ii) the Transaction Agreement is terminated by either us or Buyer because stockholder approval was not obtained or by us if the transaction had not closed by the end date (in each case, other than a termination giving rise to a right of Buyer to receive the termination fee in the event described above), then we will pay to Buyer the Buyer Expenses;
•: if, following the termination of the Transaction Agreement giving rise to an obligation of us to pay the Buyer Expenses pursuant to the situation described immediately above, we enter into a definitive agreement with respect to, or consummate, a transaction contemplated by any alternative proposal within twelve months of said termination date (provided that the references to "20%" in the definition of alternative proposal will be deemed to be references to "50%"), then we will pay to Buyer the termination fee as redefined; and
•: if the Transaction Agreement is terminated by us because the transaction has not closed by the end date, or because of Buyer's breach or Buyer's failure to close (in each case as described above under "—Termination of the Transaction Agreement") and at the time of termination all mutual closing conditions and Buyer's conditions have been satisfied (other than any condition the failure of which to be satisfied has been proximately caused by the Buyer's breach of the

Transaction Agreement and conditions that, by their nature, are to be satisfied at closing and which were, at the time of termination capable of being satisfied), then:

•: if, at the time of such termination, the lender under Buyer's debt financing commitment has failed to fund the debt financing contemplated by such commitment, Buyer will pay us a termination fee of $37.5 million; or
•: if, at the time of such termination, the financing party under Buyer's third party equity commitment has failed to fund the equity financing contemplated by such commitment, Buyer will pay us a termination fee of $50 million;

provided that, if both termination fees are due, then only the equity commitment termination fee will be due.

The right to receive payment of any termination fees as described above will be the exclusive remedy of the party seeking the termination fees against the other party and its related parties and other representatives for the loss suffered as a result of the failure of the transaction to be consummated and any other losses, damages, obligations or liabilities suffered as a result of or under the Transaction Agreement. Except as set forth in the termination fees provision of the Transaction Agreement, such party owing the termination fees will have no further liability or obligation relating to or arising out of the Transaction Agreement.

Indemnification (page 63)

Both parties agree to indemnify the other party under certain circumstances after the closing of the transaction as more fully described in this proxy statement and the Transaction Agreement.

Interests of Certain Directors and Executive Officers in the Asset Sale (page 38)

When considering the recommendation by our board of directors, you should be aware that a number of our executive officers and directors have interests in the asset sale that are different from the interests of our other stockholders. Our board of directors was aware of these interests and considered them, among other matters, in unanimously approving and adopting the Transaction Agreement and the transactions contemplated by the Transaction Agreement, including the asset sale. Such interests relate to, or arise from, among other things:

•: the fact that pursuant to their original terms of issuance, unvested ARC equity awards held by all awards holders, which are comprised of our four executive officers, two of whom are also board members, will vest upon the closing of the asset sale; and
•: the potential of certain of our executive officers to receive payments under severance agreements.

Each of these additional interests is described in this proxy statement to the extent material, and, except as described in this proxy statement, such persons have to our knowledge no material interest in the asset sale apart from those of stockholders generally.

Tax Consequences of the Asset Sale (page 41)

The sale of our assets pursuant to the Transaction Agreement will be a taxable transaction to the Sellers for United States Federal income tax purposes as discussed in this proxy statement.

No Appraisal Rights (page 41)

The Maryland General Corporation Law provides for stockholder appraisal rights in connection with the sale of substantially all of a company's assets. However, pursuant to state law, we have

opted-out of such rights in our Charter. Accordingly, there are not any stockholder appraisal rights available to holders of our common stock or special voting stock in connection with the asset sale.

Regulatory Approvals (page 41)

The asset sale is not subject to review by the United States Federal Trade Commission, or FTC, and the Antitrust Division of the United States Department of Justice, or DOJ, under the HSR Act. Nevertheless, the FTC and DOJ may choose to review the transaction, although this would not be customary.

We are not aware of any other material regulatory requirements or governmental approvals or actions that may be required to consummate the asset sale, except for compliance with the applicable regulations of the Securities and Exchange Commission, or the SEC, in connection with this proxy statement and compliance with the Maryland General Corporation Law in connection with the asset sale. Should any such approval or action be required, it is presently contemplated that such approval or action would be sought. There can be no assurance, however, that any such approval or action, if needed, could be obtained and would not be conditioned in a manner that would cause the parties to abandon the asset sale.

QUESTIONS AND ANSWERS ABOUT THE ASSET SALE,
THE TRANSACTION AGREEMENT AND THE SPECIAL MEETING

Following are some commonly asked questions that may be raised by our stockholders and answers to each of those questions.

1. WHAT AM I BEING ASKED TO VOTE ON AT THE SPECIAL MEETING?

Our stockholders will be asked to:

•: consider and vote upon a proposal to approve the sale of substantially all of our assets, including the operating assets used in our manufactured home communities business and our retail sales and financing businesses, but excluding our recently acquired insurance subsidiary, NLASCO, pursuant to the Transaction Agreement, dated as of April 17, 2007, by and among Affordable Residential Communities Inc., Affordable Residential Communities LP, the other seller parties named in the Transaction Agreement and American Riverside Communities LLC, an affiliate of Farallon Capital Management, L.L.C.;
•: consider and vote upon a proposal to approve any motion to adjourn or postpone the special meeting to a later date to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the foregoing proposal; and
•: transact any other business as may properly come before the special meeting or any adjournments or postponements of the special meeting.

All holders of our common stock, par value $0.01 per share, and special voting stock, par value $0.01 per share, as of the close of business on , 2007, the record date for our special meeting, will vote collectively as one class on all matters submitted to a vote of stockholders at the special meeting.

2. WHAT WILL HAPPEN IF THE ASSET SALE IS APPROVED BY OUR STOCKHOLDERS?

If the asset sale pursuant to the Transaction Agreement is approved by our stockholders, we will sell substantially all of our assets, including our operating assets used to own and operate our manufactured home communities and business related thereto to Buyer under the terms of the Transaction Agreement, as more fully described in this proxy statement. Following the sale of the assets, we will only have the NLASCO business, the cash proceeds of the sale and certain retained obligations.

3. WHAT WILL HAPPEN IF THE ASSET SALE IS NOT APPROVED BY OUR STOCKHOLDERS?

If the asset sale is not approved by our stockholders, we will not sell our assets to Buyer at this time and we will continue to conduct our business in the ordinary course and evaluate all available strategic alternatives. Thereafter, either party would have the right to terminate the Transaction Agreement. Upon termination we would be required to pay to Buyer the amount of the Buyer Expenses and, under certain circumstances as described above under "—Termination Fees; Expense Reimbursement" could be required to pay the termination fee to Buyer if we subsequently entered into an agreement for, or consummated, an alternative transaction.

4. WHEN IS THE ASSET SALE EXPECTED TO BE COMPLETED?

If the asset sale pursuant to the Transaction Agreement is approved at the special meeting, we expect to complete the asset sale as soon as practicable after all of the conditions in the Transaction Agreement have been satisfied or waived. The parties are working toward satisfying the conditions to

closing and completing the asset sale as soon as reasonably possible. We expect to be able to complete the asset sale by the end of 2007.

5. HOW WAS THE PURCHASE PRICE FOR THE ASSETS DETERMINED?

The purchase price for the assets proposed to be sold to Buyer was negotiated between our representatives and representatives of Buyer. We have received a fairness opinion from Sandler O'Neill that the consideration in the transaction is fair, from a financial point of view, to us. A copy of the fairness opinion of Sandler O'Neill is included as Annex C to this proxy statement.

6. AM I ENTITLED TO APPRAISAL RIGHTS IN CONNECTION WITH THE ASSET SALE?

No. Although the Maryland General Corporation Law provides for stockholder appraisal rights in connection with the sale of a company's assets, pursuant to state law we have opted-out of such rights in our Charter.

7. WHAT WILL HAPPEN TO MY ARC SHARES IF THE ASSET SALE IS APPROVED?

The asset sale will not alter the rights, privileges or nature of the outstanding shares of our stock. A stockholder who owns shares of our stock immediately prior to the closing of the asset sale will continue to hold the same number of shares immediately following the closing. We do not intend to distribute any of the proceeds that we receive from the transaction to our stockholders. Rather, we intend to use any proceeds from the transaction, along with our existing cash and cash equivalents, in connection with our future business plans. In addition, we currently anticipate seeking to make opportunistic acquisitions with the proceeds.

8. HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THE PROPOSALS?

The board of directors recommends that you vote "FOR" (1) the proposal to approve the asset sale pursuant to the Transaction Agreement, and (2) the proposal to adjourn or postpone the special meeting to a later date to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the foregoing proposals. Abstentions will have the same effect as a vote "AGAINST" the asset sale proposal and no effect on the vote on the adjournment or postponement proposal.

9. HOW DO I VOTE IF I DO NOT ATTEND THE SPECIAL MEETING?

If you hold your shares in your name, you may authorize a proxy by telephone, via the Internet or by mail, as specified below:

•: Authorizing a proxy by Telephone: You can authorize a proxy for your shares by telephone until 11:59 p.m. Eastern Standard Time on , 2007 by calling the toll-free telephone number on the enclosed proxy card. Telephone proxy authorization is available 24 hours a day. Easy-to-follow voice prompts allow you to authorize a proxy for your shares and confirm that your instructions have been properly recorded. Our telephone proxy authorization procedures are designed to authenticate stockholders by using individual control numbers;
•: Authorizing a proxy via the Internet: You can authorize a proxy via the Internet until 11:59 p.m. Eastern Standard Time on , 2007 by accessing the web site listed on your proxy card and following the instructions you will find on the web site. Internet proxy authorization is available 24 hours a day. As with telephone proxy authorization, you will be given the opportunity to confirm that your instructions have been properly recorded; and
•: Authorizing a proxy by Mail: If you choose to authorize a proxy by mail, simply mark the enclosed proxy card, date and sign it, and return it in the postage paid envelope provided.

By casting your vote in any of the three ways listed above, you are authorizing the individuals listed on the proxy to vote your shares in accordance with your instructions. If your shares are held in the name of a bank, broker or other agent or nominee, you will receive instructions from the holder of record that you must follow for your shares to be voted. Please follow their instructions carefully.

10. CAN I CHANGE MY VOTE?

Yes. You may change your proxy instructions at any time before your proxy is voted at the special meeting. Proxies may be revoked by taking any of the following actions:

•: filing a written notice of revocation with our corporate secretary at our principal executive office (Affordable Residential Communities Inc., 7887 E. Belleview Ave., Suite 200, Englewood, CO 80111, attention: Scott L. Gesell, Executive Vice President, General Counsel and Corporate Secretary);
•: filing a properly executed proxy showing a later date with our corporate secretary at our principal executive office;
•: properly authorizing a proxy on a later date by telephone or via the Internet (only your last telephone or Internet proxy will be counted) before 11:59 p.m. Eastern Standard Time on , 2007; or
•: attending the special meeting and voting in person (although attendance at the meeting will not, by itself, revoke a proxy).

11. WHAT SHARES ARE INCLUDED ON THE PROXY CARD(S)?

The shares on your proxy card(s) represent ALL of your shares. If you do not return your proxy card(s) or authorize a proxy by telephone or via the Internet your shares will not be voted.

12. WHAT DOES IT MEAN IF I GET MORE THAN ONE PROXY CARD?

If your shares are registered differently and are in more than one account, you will receive more than one proxy card. Sign and return, or vote pursuant to the above instructions, all proxy cards to ensure that all your shares are voted.

13. WHO IS ENTITLED TO VOTE AT THE SPECIAL MEETING?

Only holders of record of our common stock and special voting stock as of the close of business on , 2007 are entitled to notice of and to vote at the special meeting.

14. HOW MANY SHARES WERE OUTSTANDING ON THE RECORD DATE?

At the close of business on , 2007 there were shares of common stock and shares of special voting stock outstanding entitled to vote. A stockholder may vote (a) shares that are held of record directly in the stockholder's name, and (b) shares held for the stockholder, as the beneficial owner, through a broker, bank or other agent or nominee. At the meeting, each outstanding share of common stock will be entitled to one vote and each share of special voting stock will be entitled to 0.519 of a vote.

15. WHAT IS A "QUORUM" FOR PURPOSES OF THE SPECIAL MEETING?

In order to conduct business at the special meeting, a quorum must be present. The presence in person or by proxy of stockholders entitled to cast a majority of all the votes entitled to be cast at the special meeting will constitute a quorum. Both abstentions and broker non-votes, if any, are counted as shares present for the purpose of determining the presence of a quorum.

16. WHAT VOTE IS REQUIRED TO APPROVE EACH PROPOSAL?

Once a quorum has been established, for the asset sale to be approved, the affirmative vote of holders of shares of our common stock and special voting stock entitled to cast at least a majority of all votes entitled to be cast on the matter at our special meeting, voting as a single class, is required. Once a quorum has been established, for the adjournment or postponement proposal, the affirmative vote of a majority of the votes cast is required.

If your shares are held in street name, your broker will vote your shares for you for the approval of the transactions contemplated by the Transaction Agreement only if you provide instructions to your broker on how to vote your shares. You should follow the directions provided by your broker regarding how to instruct your broker to vote your shares. Because the affirmative vote of holders of shares of our common stock and special voting stock entitled to cast at least a majority of all votes entitled to be cast on the matter at our special meeting, voting as a single class, is required to approve the asset sale, a failure to provide your broker with instructions on how to vote your shares will have the effect of a vote "AGAINST" that proposal. Broker non-votes, if any, will not have an affect on the proposal to adjourn or postpone the special meeting, if necessary, to solicit additional proxies.

17. WHAT HAPPENS IF I ABSTAIN?

Proxies marked "abstain" will be counted as shares present for the purpose of determining the presence of a quorum, but for purposes of determining the outcome of the proposal to approve the transactions contemplated by the Transaction Agreement, shares represented by such proxies will be treated as a vote "AGAINST" such proposal. Abstentions will have no effect on the proposal to adjourn or postpone the special meeting, if necessary, to solicit additional proxies.

18. HOW WILL VOTING ON ANY OTHER BUSINESS BE CONDUCTED?

Although we do not know of any business to be considered at the special meeting other than the asset sale proposal described in this proxy statement, if any other business is properly presented at the special meeting, your signed proxy card gives authority to the proxy holders to vote on such matters at their discretion.

19. WHO WILL BEAR THE COST OF THIS SOLICITATION?

We are soliciting proxies and will pay the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials. We will provide copies of these proxy materials to brokerages, banks and other agents or nominees holding in their names shares of our common stock and special voting stock beneficially owned by others so that they may forward these proxy materials to the beneficial owners. We may solicit proxies by personal interview, mail, telephone and electronic communications. We have retained MacKenzie Partners, Inc., as proxy solicitor, to assist with the solicitation of proxies for the special meeting and have agreed to pay them a fee for these services, which it reasonably estimates to be approximately $25,000, plus reasonable expenses. Our directors, officers, and employees (acting without additional compensation) may assist in soliciting proxies by telephone, email, or direct contact. We may reimburse brokerage firms and other persons representing beneficial owners of shares for their expenses in forwarding solicitation materials to the beneficial owners.

20. WHO CAN I CALL WITH QUESTIONS ABOUT THE SPECIAL MEETING?

For more information, you should contact our proxy solicitor, MacKenzie Partners, Inc., toll-free at 1-(800)-322-2885, bankers and brokers may call collect at (212)-929-5500.

•: consider and vote upon a proposal to approve any motion to adjourn or postpone the special meeting to a later date to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the foregoing proposal; and
•: transact any other business as may properly come before the special meeting or any adjournments or postponements of the special meeting.

Voting Securities; Quorum

Only holders of record of our common stock and special voting stock at the close of business on , 2007, the record date, are entitled to notice of and to vote at the special meeting.

Holders of record of our common stock on the record date are entitled to one vote per share at the special meeting on each proposal and holders of record of our special voting stock on the record date are entitled to 0.519 of a vote per share at the special meeting on each proposal.

A quorum is necessary to hold a valid special meeting. The presence in person or by proxy of stockholders entitled to cast a majority of all the votes entitled to be cast at the special meeting on any matter will constitute a quorum. Both abstentions and broker non-votes, if any, are counted as present for the purpose of determining the presence of a quorum.

Votes Required for Approval

majority of the votes cast at our special meeting. If we fail to obtain the requisite vote for the asset sale proposal, we will not be able to consummate the asset sale and either party may terminate the asset purchase agreement. If we fail to obtain the requisite vote for the adjournment and postponement proposal, we will not be able to adjourn or postpone the special meeting, if necessary, to solicit additional proxies.

Each of Gerald J. Ford, ARC Diamond, LP and Hunter's Glen/Ford, Ltd., who as of April 17, 2007 collectively beneficially owned an aggregate of 9,421,642 shares of voting securities, representing approximately 16.0% of the votes entitled to be cast at the special meeting, entered into a Support Agreement, a copy of which is included as Annex B to this proxy statement. Pursuant to such Support Agreement, each such person agreed to vote, or cause to be voted, all of the shares owned by such person in favor of the transaction and other proposals described in this proxy statement and against any alternative transaction. Also, the Buyer has informed us that certain of its affiliates intend to vote their shares of our voting securities, representing approximately 9.6% of the votes entitled to be cast at the special meeting, in favor of the transaction and other proposals relating thereto.

Voting Your Shares and Changing Your Vote

You may vote by proxy, in person at the special meeting or by authorizing a proxy via telephone or the Internet.

Voting in Person

If you plan to attend the special meeting and wish to vote in person, you will be given a ballot at the special meeting. Please note, however, that if your shares are held in "street name," which means your shares are held of record by a broker, bank or other agent or nominee, and you wish to vote at the special meeting, you must bring to the special meeting a form of legal proxy requested through your broker, bank or other agent or nominee authorizing you to vote at the special meeting.

Voting by Proxy

All shares represented by properly executed proxies received in time for the special meeting will be voted at the special meeting in the manner specified by the stockholders giving those proxies. Properly executed proxies that do not contain voting instructions will be voted "FOR" each proposal.

Revocation of Proxy

Submitting a proxy on the enclosed form does not preclude a stockholder from voting in person at the special meeting. A stockholder of record may revoke a proxy at any time before it is voted by filing with our corporate secretary a duly executed revocation of proxy, by submitting a duly executed proxy to our corporate secretary with a later date, by calling the toll free telephone number on the proxy card, by logging on via the Internet and revoking your vote, or by appearing at the special meeting and voting in person. Attendance at the special meeting without voting will not itself revoke a proxy. If your shares are held in street name, you must contact your broker, bank or other agent or nominee to revoke your proxy. We have also made arrangements with Mackenzie Partners, Inc. to assist the board in soliciting proxies.

How Proxies are Counted

Only shares affirmatively voted "FOR" each proposal and shares represented by properly executed proxies that do not contain voting instructions will be counted as favorable votes for each proposal. Shares of our common stock and special voting stock held by persons attending the special meeting but not voting, and shares of our common stock and special voting stock for which we received proxies but with respect to which holders of those shares have abstained from voting, will have the same effect as

votes "AGAINST" the asset sale proposal for purposes of determining whether or not the requisite vote was received. Any signed proxies received by us will be voted in favor of an adjournment or postponement of the special meeting unless contrary voting instructions are given. Shares of our common stock and special voting stock for which we received proxies but with respect to which holders of those shares have abstained from voting will have no effect on the adjournment or postponement proposal for purposes of determining whether or not the requisite vote was received.

Cost of Solicitation

We are soliciting proxies for the special meeting from our stockholders. We will bear the entire cost of soliciting proxies from our stockholders. In addition to the solicitation of proxies by mail, Internet and telephone, we will request that banks, brokers and other record holders send proxies and proxy materials to the beneficial owners of our common stock and special voting stock held by them and secure their voting instructions, if necessary. We will reimburse those record holders for their reasonable expenses in so doing. We have also retained MacKenzie Partners, Inc. as proxy solicitor, to assist with the solicitation of proxies for the special meeting and have agreed to pay it a fee for these services, which it reasonably estimates to be approximately $25,000, plus reasonable expenses.

SUMMARY OF SELECTED HISTORICAL AND PRO FORMA FINANCIAL INFORMATION

The following tables present summary and historical financial information and pro forma combined information for ARC. We have also provided summary historical financial information for NLASCO for periods prior to its acquisition by us. NLASCO is a property and casualty insurance business that we acquired on January 31, 2007.

Our pro forma condensed consolidated balance sheet reflects adjustments to our historical financial data to give effect to (i) the sale of the manufactured home communities business, and (ii) the related repayment of other indebtedness and payment of other costs, as if each had occurred on March 31, 2007.

The historical financial information of ARC for the years ended December 31, 2006, 2005 and 2004 is substantially representative of the financial results of the manufactured home communities business to be sold to the Buyer because the acquisition of NLASCO, a property and casualty insurance business which is being retained by ARC, did not occur until January 2007. We have included in Annex D the financial statements of the manufactured home communities business for the quarterly period ended March 31, 2007 that exclude the financial results of NLASCO. After the sale of the manufactured home communities business, the Senior Exchangeable Notes due 2025 and the Series A Preferred Stock will remain with ARC. The business to be sold encompasses the combined interests of ARC's common stockholders and OP Unitholders, whose interests are treated as minority interests in the consolidated financial statements.

The summary historical and pro forma financial data set forth below should be read in conjunction with the consolidated financial statements and accompanying notes for each of ARC and NLASCO appearing elsewhere in this proxy statement or incorporated by reference.

You are cautioned that these statements are only projections and that forward-looking statements are subject to a number of risks, assumptions and uncertainties that could cause actual results to differ materially from those projected in such forward-looking statements. These risks, assumptions and uncertainties include, but are not limited to: future decisions by the SEC, or other governmental or regulatory bodies; the vote of ARC stockholders; business disruptions resulting from the announcement of the asset sale; uncertainties related to litigation; economic and political conditions in the United States; and other risks outlined in our filings with the SEC, including the annual report on Form 10-K for the year ended December 31, 2006. All forward-looking statements are effective only as of the date they are made and we disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

ASSET SALE RISK FACTORS

You should carefully consider the following risk factors relating to the asset sale before you decide whether to vote for the proposal to approve the asset sale pursuant to the Transaction Agreement. You should also consider the other information in the proxy statement and the additional information in our other reports on file with the SEC.

Our business may be harmed if the proposed asset sale of our manufactured home communities business is not consummated.

On April 17, 2007, we entered into a Transaction Agreement with American Riverside Communities LLC, an affiliate of Farallon Capital Management, L.L.C., or Farallon, pursuant to which we agreed to sell all of our and our subsidiaries' assets primarily relating to the manufactured home communities business, including the owning and operating of manufactured home communities, the provision of related financing services, and business related thereto, but excluding the insurance business of NLASCO and related insurance activities. The asset sale is subject to a number of contingencies, including approval by our stockholders and other customary closing conditions. We cannot predict whether we will succeed in obtaining the approval of our stockholders. As a result, we cannot assure you that the asset sale will be completed. If the asset sale is not completed, we will be subject to several risks, including the following:

•: our cash flow and financial condition could be adversely affected if we are unable to complete the asset sale because, among other items, costs incurred could not be capitalized;
•: under certain specified circumstances, we may be required to pay Buyer a termination fee of $20 million and reimburse it for transaction expenses up to $5 million upon the termination of the Transaction Agreement;
•: the price of our common stock may decline to the extent that the current market price of our common stock reflects an assumption that the asset sale will occur or that failure to close reflects that our current market trading price is not accurate;
•: we must pay our accrued costs related to the asset sale, such as legal, accounting and certain financial advisory fees, even if the asset sale is not completed; and
•: the announcement of the transaction, the failure to close and the uncertainty caused by each might have a disruptive affect on our employees, residents and vendors, which in turn could have a disruptive or harmful affect on our ability to conduct our business.

If our stockholders do not approve the asset sale pursuant to the Transaction Agreement, we would have to continue to operate the manufactured home communities business if no other offers for their purchase were made and consummated.

If our stockholders do not approve the asset sale we may seek another strategic transaction, including the sale of all or part of our business. Although we have had such discussions with various parties in the past, none of these parties may now have an interest in a strategic transaction with us or be willing to offer a favorable purchase price.

By completing the asset sale with the Buyer, we will no longer be engaged in a business primarily based on real estate.

The most significant portion of our assets today are real estate assets. Following the asset sale, these real estate assets will be sold and the remaining assets will be non-real estate assets, including the NLASCO business, cash proceeds from the asset sale and ongoing net operating losses, or NOLs. By selling substantially all of our assets, including operating assets used in our manufactured home

communities business to Buyer, we will be exiting the manufactured home community business. We will subsequently become primarily focused on the NLASCO insurance business and the utilization of the cash proceeds from the asset sale.

We will engage in strategic acquisitions, and investments.

We anticipate seeking to make opportunistic acquisitions with certain of the proceeds from the asset sale. However, there is no assurance that we will be able to identify suitable acquisitions, consummate acquisitions or successfully integrate acquired personnel and operations. Even if we identify suitable acquisitions, we may not be able to make acquisitions or investments on commercially acceptable terms, if at all. The success of any acquisition will depend upon, among other things, the ability of management and our employees to integrate acquired personnel, operations, products and technologies into our organization effectively, to retain and motivate key personnel of acquired businesses and to retain customers and clients of acquired businesses. In addition, any acquisitions we undertake may involve certain other risks, including consumption of available cash resources, potentially dilutive issuances of equity securities and the diversion of management's attention from other business concerns. We may also need to make further investments to support the acquired company and may have difficulty identifying and acquiring the appropriate resources. There can be no assurance that any acquisitions we undertake will perform as expected. We may enter, on our own and through acquisitions, into new lines of business or initiate new service offerings, whether related or unrelated to our insurance business. Our success in any such endeavor will depend upon, among other things, the ability of management to identify suitable opportunities, successfully implement sound business strategies and avoid the legal and business risks of any new line of business or service offering and/or an acquisition related thereto. There can be no assurance that we will be able to do any of the foregoing. In addition, any such undertakings may result in additional costs without an immediate increase in revenues and may divert management's attention from the operation and growth of our core business.

INFORMATION ABOUT THE COMPANIES AND THE ASSET SALE

This section of the proxy statement describes certain aspects relating to the sale of substantially all of our operating assets used in our manufactured home communities business to Buyer. However, this description may not be complete or may not provide all the information that may be important to you. We highly recommend that you carefully read the complete Transaction Agreement included as Annex A to this proxy statement for the precise legal terms of the transaction and other information that may be important to you.

Terms of the Transaction Agreement

At the closing Buyer will purchase from us all of our and our subsidiaries' assets primarily relating to the manufactured home communities business, including the owning and operating of manufactured home communities, the provision of related financing services, and business related thereto, but excluding the insurance business of NLASCO and related insurance activities, in exchange for cash in the amount of the excess of $1.794 billion over the amount of Assumed Indebtedness as of the closing of the transaction, as such amount is adjusted as described under "The Transaction Agreement—Purchase Price Adjustments". After giving effect to estimated expenses and taxes, the amount realized by us is estimated to be approximately $540 million to $550 million net of retained debt and preferred stock. The proceeds from the asset sale will be retained by us and will be used for general working capital purposes and to pay off existing obligations. In addition, we currently anticipate seeking opportunistic acquisitions with certain of the proceeds. Stockholders will not receive any proceeds from the asset sale. The Transaction Agreement is the primary legal document governing the rights and obligations of the parties. In the Transaction Agreement, we make certain representations and warranties and agree to perform or to refrain from performing certain actions. Stockholders are urged to carefully read the Transaction Agreement in its entirety, a copy of which is attached as Annex A to this proxy statement.

Use of Proceeds

Under the terms of the Transaction Agreement and after giving effect to estimated expenses and taxes, the amount realized by us is estimated to be approximately $540 million to $550 million net of retained debt and preferred stock as more fully described in Annex D, Selected ARC Historical Financial Data and Unaudited Proforma Condensed Consolidated Financial Statements as of March 31, 2007, note (a). We will use a portion of the proceeds for general working capital and to repay outstanding obligations. In addition, we currently anticipate seeking to make opportunistic acquisitions with certain of the proceeds. We do not intend to distribute any of the proceeds that we receive from the asset sale to our stockholders. Rather, we intend to use any proceeds from the transaction, along with our existing cash and cash equivalents, in connection with our future business plans.

Background of the Asset Sale

At various times during February 2007, a representative of Farallon, acting in its capacity as one of our largest shareholders, discussed with members of our board of directors matters relating to our operations and prospects. On March 8, 2007, in order to permit us to provide non-public information to Farallon regarding our business, we entered into a confidentiality agreement with Farallon. Thereafter, representatives of Farallon conducted financial and business due diligence on our manufactured home community business.

On March 2, 2007, representatives of Lone Star U.S. Acquisitions, LLC (which we refer to as Lone Star), an investment fund focused on real estate acquisitions, contacted us and expressed a similar interest in acquiring our manufactured home community business. We entered into a confidentiality agreement with Lone Star on March 2, 2007.

On Friday, March 30, 2007, a representative of Farallon spoke with a member of our board of directors and expressed Farallon's interest in acquiring our manufactured home community business.

On Monday, April 2, 2007, our representatives, representatives of Farallon and counsel from Paul, Weiss, Rifkind, Wharton & Garrison, LLP, counsel to Farallon, met in New York at the offices of Skadden, Arps, Slate, Meagher and Flom, LLP, or Skadden, our primary legal counsel. The parties

discussed the potential acquisition by Farallon of substantially all of our assets, excluding the assets of NLASCO, for approximately $1.85 billion in cash, subject to further negotiations and other terms of the transaction, including deal structure and termination provisions. In addition, in consideration of the time and resources that Farallon had devoted and expected to continue to devote to the transaction, our representatives and representatives of Farallon at this meeting initiated negotiations of the terms of an exclusivity agreement, which negotiations continued for the remainder of the week. On Friday, April 6, the parties executed an exclusivity agreement pursuant to which we and Farallon agreed to work in good faith to negotiate a possible transaction on an exclusive basis through April 16, 2007. On Monday, April 9, we publicly disclosed the proposed material terms of the transaction. On the same day, we and Farallon publicly disclosed that the parties had entered into an exclusivity agreement and copies of the agreement were filed with the SEC.

On April 4, 2007, we engaged Sandler O'Neill, to render an opinion as to whether the consideration to be received in the transaction to sell our manufactured community business would be fair, from a financial point of view, to us.

On April 5, 2007, our representatives distributed to representatives of Farallon a draft transaction agreement for review, and over the next 12 days our representatives and representatives of Farallon continued to engage in discussions concerning a possible transaction and exchanged drafts of a transaction agreement. In addition to negotiating and drafting the Transaction Agreement, we and Farallon, with the assistance of our respective legal counsels, also prepared and negotiated other ancillary agreements, including disclosure schedules, a Support Agreement pursuant to which Mr. Ford and his affiliates would agree to vote their shares in favor of the asset sale at a stockholders meeting to approve the transaction and against any alternative transaction, a Notes Support Agreement pursuant to which Farallon and its affiliates would agree to give their consent in a consent solicitation with respect to ARC LP exchange notes and a limited guarantee in favor of us pursuant to which Farallon Capital Partners, L.P. would guarantee, subject to the terms, conditions and limitations set forth in that agreement, certain payment obligations of the Buyer under the Transaction Agreement.

In accordance with the exclusivity agreement, our representatives negotiated exclusively with representatives of Farallon regarding the proposed transaction from the date of the exclusivity agreement through April 12. On Wednesday, April 11, we received a written, unsolicited proposal from Lone Star to purchase our manufactured home community business. Management reviewed and discussed the proposal with our board of directors. On Thursday, April 12, our board of directors determined (after consultation with its legal advisors and its financial advisors) that the proposal from Lone Star was reasonably likely to result in a "superior proposal" (as that term was defined under the exclusivity agreement with Farallon) and promptly informed Farallon of the receipt of the Lone Star proposal in accordance with the terms of the exclusivity agreement. On Friday, April 13, we commenced discussions with Lone Star.

From April 13 through April 17, we engaged in negotiations with both Farallon and Lone Star. Each of the negotiations involved multiple drafts of related transaction documents, as well as discussions regarding deal structure and pricing, including, among other things, whether we would be responsible for defeasing or pre-paying the indebtedness associated with the properties to be sold, termination fees, and the scope of excluded assets and liabilities. Throughout this process, our board of directors and Sandler O'Neill were kept informed of the status and progress of the negotiations with both parties.

On April 16, our board of directors met (with some directors attending in person and other directors attending telephonically) to review the proposed transaction with Farallon and the proposed transaction with Lone Star. At this meeting, representatives of Skadden presented information regarding both proposed transactions. The structural difference between the two transactions, defeasance of debt, assumption of debt and the effect upon the certainty and timing of closing was

discussed. Representatives of Sandler O'Neill presented the terms and financial analysis of the transaction proposed by Farallon at that time. Sandler O'Neill delivered no opinion at that time regarding either the transaction proposed by Farallon or proposed by Lone Star. Because both sets of negotiations had progressed to a point where our board of directors was of the opinion that either was acceptable, our board of directors approved both the proposed transaction with Farallon and the proposed transaction with Lone Star, and appointed a special committee consisting of Messrs. Ford and Willard to finalize the negotiations of both agreements and to enter into whatever agreement, if any, the special committee deemed in our best interests. Negotiations with Farallon and Lone Star continued through the night of April 16 and the morning of April 17. Farallon increased the amount of consideration in their proposal and modified its structure. The special committee moved forward with the modified Farallon proposal, the consideration from which was greater than the consideration reviewed by Sandler O'Neill with our board of directors on April 16, 2007. On April 17, Sandler O'Neill provided an oral opinion, subsequently confirmed in writing, that the consideration to be received in the proposed transaction with Farallon was fair, from a financial point of view, to us. The special committee approved the transaction with Farallon and consequently the Transaction Agreement between us and Farallon, as well as the Notes Support Agreement, the limited guarantee and the Support Agreement, were entered into. Also on April 17, we issued a press release announcing the transaction with Farallon, and filed the transaction documents with the SEC on a Current Report on Form 8-K.

Reasons for the Asset Sale

In reaching its determination, our board of directors consulted with management and its legal and financial advisors. In arriving at its determination, our board of directors also considered a number of factors, including but not limited to:

•: the business, operations, management, financial condition, earnings and cash flows of our company on a historical and prospective basis;
•: the financial and other terms of the proposed asset sale, the Transaction Agreement and related documents;
•: the current and prospective environment in which we operate, including national economic conditions, the competitive environment in the industry generally, the regulatory environment faced by us and the likely effect of these factors on us;
•: the fit of our business with Farallon and Riverside Management LLC and the expectation that the asset sale would entail minimal disruption for our customers;
•: the potential impact of the transaction on our employees and other key constituencies;
•: the required consents needed for the completion of the asset sale and the likelihood that such required consents would be received;
•: the fairness opinion dated April 17, 2007 delivered by Sandler O'Neill that, as of that date and based on and subject to the respective assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken as described in the opinion, the consideration to be received in the Farallon transaction was fair, from a financial point of view, to us; and
•: presentations and discussions with our senior management and representatives of our primary legal counsel, Skadden, and our financial advisor, Sandler O'Neill, regarding the principal terms of the Transaction Agreement and other related documents.

Each of these factors favored the conclusion by our board of directors that the asset sale to Buyer is advisable, fair to, and in our best interest and the best interest of our stockholders. Our board of

directors relied on management to provide accurate and complete financial information, projections and assumptions as the starting point for its analysis.

Our board of directors also considered a variety of risks and other potentially negative factors relating to the Transaction Agreement and the transactions contemplated by it. These factors included:

•: the risk factors described above under "Asset Sale Risk Factors";
•: the possibility that the transaction may not be completed, which would divert significant resources and would have a negative impact on our operations;
•: the effects of the announcement of the asset sale on employees and customers;
•: the transaction costs that would be incurred in connection with the asset sale;
•: the necessity to obtain any regulatory approvals required to consummate the asset sale; and
•: the fact that, for U.S. Federal income tax purposes, the transaction may be taxable.

Our board of directors believes that sufficient procedural safeguards were and are present to ensure the fairness of the asset sale and to permit our board of directors to represent effectively the interests of our stockholders. These procedural safeguards include the following:

•: the active negotiations between the parties to the Transaction Agreement regarding the consideration and the other terms of the Transaction Agreement and the asset sale; and
•: the retention and receipt of advice from Sandler O'Neill, our financial advisor, with respect to the fairness of the asset sale from a financial point of view as of the date of such opinion, to us of the consideration to be received by us based on and subject to the respective assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken described in the opinion.

This discussion of the information and factors considered by our board of directors in reaching its conclusions and recommendation includes all of the material factors considered by our board of directors but is not intended to be exhaustive. In view of the wide variety of factors considered by our board of directors in evaluating the Transaction Agreement and the transactions contemplated by it, and the complexity of these matters, our board of directors did not find it practicable to, and did not attempt to, quantify, rank or otherwise assign relative weight to those factors. In addition, different members of our board of directors may have given different weight to different factors.

Recommendation of Our Board of Directors

Our board of directors has determined that the asset sale to Buyer is in our best interest and the best interest of our stockholders. Our board of directors has approved the asset sale pursuant to the Transaction Agreement and recommends that the stockholders vote "FOR" (i) the proposal to approve the asset sale pursuant to the Transaction Agreement and (ii) the proposal to adjourn or postpone the special meeting, if necessary, to solicit additional proxies.

Opinion of Our Financial Advisor

By letter dated April 4, 2007, ARC retained Sandler O'Neill to act as its financial advisor in connection with a possible business combination with a second party. Sandler O'Neill is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Sandler O'Neill is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Sandler O'Neill acted as financial advisor to ARC in connection with the transaction and participated in certain of the negotiations leading to the Transaction Agreement. On April 17, 2007, Sandler O'Neill delivered to the ARC board its oral opinion, subsequently confirmed in writing that, as of such date, the purchase price to be received in the transaction was fair to ARC from a financial point of view. In rendering its opinion, Sandler O'Neill confirmed the appropriateness of its reliance on the analyses used to render its opinion by reviewing the assumptions upon which its analyses were based and reviewing the other factors considered in rendering its opinion. The full text of Sandler O'Neill's opinion is attached as Annex C to this proxy statement. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O'Neill in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the opinion. ARC's stockholders are urged to read the entire opinion carefully in connection with their consideration of the transaction.

Sandler O'Neill's opinion speaks only as of the date of the opinion. The opinion is directed to ARC's board and speaks only to the fairness from a financial point of view of the purchase price to be received by ARC in the transaction. It does not address the underlying business decision of ARC to engage in the transaction or any other aspect of the transaction and is not a recommendation to any ARC stockholder as to how such stockholder should vote at the special meeting with respect to the transaction, or any other matter.

In connection with rendering its April 17, 2007 opinion, Sandler O'Neill reviewed and considered, among other things:

(1) the Transaction Agreement;

(2) certain publicly available financial statements and other historical financial information of ARC that Sandler O'Neill deemed relevant;

(3) internal financial projections for ARC which did not include NLASCO for the years ending December 31, 2007 through 2011, as furnished by and reviewed with senior management of ARC;

(4) certain publicly available research estimates of valuation metrics and the future financial performance of ARC and other companies Sandler O'Neill deemed to be reasonably comparable to ARC;

(5) the financial terms of other business combinations in the manufactured home communities industries of which Sandler O'Neill was aware;

(6) the current market environment generally and the manufactured home communities industry; and

(7) such other information, financial studies, analyses and investigations and financial, economic and market criteria as Sandler O'Neill considered relevant.

Sandler O'Neill also discussed with certain members of senior management of ARC the business, financial condition, results of operations and prospects of ARC, including management's assumptions regarding the future revenue streams, costs, cash flow and earnings potential of those assets and ARC interests to be sold in the transaction.

In performing its review, Sandler O'Neill relied upon the accuracy and completeness of all of the financial and other information that was available to it from public sources, that was provided to it by ARC or Buyer and their respective representatives or that was otherwise reviewed by Sandler O'Neill and assumed such accuracy and completeness for purposes of rendering its opinion. Sandler O'Neill further relied on the assurances of management of ARC that they were not aware of any facts or circumstances that would make any of such information regarding ARC or those assets and company

interests to be acquired in the transaction inaccurate or misleading. Sandler O'Neill was not asked to undertake, and did not undertake, an independent verification of the accuracy or adequacy of any of such information and Sandler O'Neill did not assume any responsibility or liability for the accuracy or completeness thereof. Sandler O'Neill did not make an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of ARC or those assets or company interests to be sold in the transaction, or the collectibility of any such assets, nor was Sandler O'Neill furnished with any such evaluations or appraisals.

Sandler O'Neill's opinion was necessarily based upon financial, economic, market and other conditions as they existed on, and could be evaluated as of, the date of its opinion. Sandler O'Neill assumed, in all respects material to its analysis, that each party to such agreements would perform all of the covenants required to be performed by such party under such agreement and that the conditions precedent in the Transaction Agreement had not been waived. Sandler O'Neill also assumed that there had been no material change in the assets, financial condition, results of operations, business or prospects of ARC or the assets and company interests to be acquired in the transaction since the date of the last financial statements made available to it and that ARC and the assets and company interests to be acquired in the transaction would remain as going concerns for all periods relevant to its analyses. Sandler O'Neill relied upon the advice ARC obtained from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Transaction Agreement and the other transactions contemplated by the Transaction Agreement.

The financial projections used and relied upon by Sandler O'Neill in its analyses for ARC were provided by and reviewed with the senior management of ARC and senior management confirmed to Sandler O'Neill that they reflected the best currently available estimates and judgments of such management of the future financial performance and revenue streams of ARC and the assets and company interests to be acquired in the transaction. For purposes of its analyses, Sandler O'Neill assumed that such performances would be achieved. Sandler O'Neill expressed no opinion as to such financial projections or the assumptions on which they were based. Those financial projections, as well as the other estimates used by Sandler O'Neill in its analysis, were based on numerous variables and assumptions which are inherently uncertain and, accordingly, actual results could vary materially from those set forth in such projections.

Financial Analysis of Sandler O'Neill

The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O'Neill believes that its analysis must be considered as a whole and that selecting portions of the factors and analyses considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its respective opinions. Also, no company included in the comparative analysis described below is identical to ARC and no transaction is identical to the transaction contemplated by the Transaction Agreement. In performing its analysis, Sandler O'Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of ARC, Buyer and Sandler O'Neill. The analysis performed by Sandler O'Neill is not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analysis. Sandler O'Neill prepared its analysis solely for purposes of rendering its opinion and provided such analysis to ARC's board on April 17, 2007. Estimates on the values of companies did not purport to be appraisals or necessarily reflect the prices at which companies or their securities might actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O'Neill's analysis does not necessarily reflect the

value of ARC's common stock or the prices at which ARC's common stock may be sold at any time. The analysis of Sandler O'Neill and its opinion were among a number of factors taken into consideration by ARC's board in making its determination to approve the Transaction Agreement and the analysis described below should not be viewed as determinative of the decision of ARC's board or management with respect to the fairness of the asset sale contemplated by the Transaction Agreement.

In discussing its April 17, 2007 opinion, Sandler O'Neill presented to ARC's board certain financial analyses of the transaction. The summary below is not a complete description of the analyses underlying the opinion of Sandler O'Neill or the presentation made by Sandler O'Neill to ARC's board, but is instead a summary of the material analyses performed and presented in connection with its opinion.

In arriving at its opinion, Sandler O'Neill did not attribute any particular weight to any analysis or factor that it considered. Rather Sandler O'Neill made its own qualitative judgments as to the significance and relevance of each analysis and factor. The financial analysis summarized below includes information presented in tabular format. Sandler O'Neill did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion; rather Sandler O'Neill made its determination as to the fairness of the purchase price on the basis of its experience and professional judgment after considering the results of all the analyses taken as a whole. Accordingly, Sandler O'Neill believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analysis and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analysis and opinion. The tables alone do not constitute complete descriptions of the financial analyses presented in such tables.

Summary of Proposal

Sandler O'Neill reviewed the financial terms of the transaction. ARC will receive cash consideration in the amount of the excess of $1.794 billion over the amount of Assumed Indebtedness as of the closing of the transaction, as such amount is adjusted as described under "The Transaction Agreement—Purchase Price Adjustments", for substantially all of its assets, including operating assets used in its manufactured home communities business, including its retail sales and financing businesses, but excluding its recently acquired insurance subsidiary, NLASCO and ARC's retained NOLs. Upon consummation of the transaction, ARC will transfer to Buyer the real estate assets associated with ARC's 275 manufactured housing communities and 57,264 homesites plus the Sunshine City community and all the corporate infrastructure and support functions, excluding those associated with ARC's NLASCO insurance operations. In addition, the acquisition of those assets used in ARC's manufactured home community business by Buyer includes ARC's tenant notes receivable, the mineral rights associated with certain real estate properties and the corporate airplane. The consideration of $1.794 billion, as adjusted, will consist of cash and assumed indebtedness. Buyer is also responsible for all of the costs and penalties incurred with the prepayment or defeasance of certain debt related to those assets used in ARC's manufactured home communities business.

Implied Value of ARC's Community Operations

Sandler O'Neill used publicly available information and information provided by the senior management of ARC to calculate an implied valuation range for ARC's community operations, making adjustments for certain other assets being sold to Buyer.

(1): Per ARC management's estimate.
(2): Assumes the Tenant Notes are acquired at 105% and 100%, respectively, of March 31, 2007 face value.
(3): Per ARC management; assumes the corporate airplane's book value.

(5): Per ARC management; expected closing date of property sale is January 2008.

Sandler O'Neill then compared the implied valuation range for ARC's community operations to the income from ARC's property operations to calculate the implied capitalization rates ("cap rates") based on actual 2006 financial results and estimated 2007 financial results provided by the senior management of ARC.

ARC's Property Operations			Actual 2006(1)			Estimated 2007(2)

Estimated Cap Rates

Sandler O'Neill reviewed the most recent publicly available cap rates used by equity research analysts in estimating ARC's net asset value. Those estimates are as follows:

Firm	Date	Cap Rates
RBC Capital Markets	03/22/07	8.0%
Merrill Lynch	03/16/07	8.5%
Cathay Financial	03/14/07	8.0%
Wachovia Capital Markets	01/03/07	8.0% - 8.5%
Citigroup	11/13/06	8.0%
BMO Capital Markets	11/08/06	7.0% - 8.0%

Sandler O'Neill noted that the above cap rates were higher than the range of implied cap rates for ARC's community operations derived from its analysis above of approximately 5.5% - 6.2%.

Comparable Company Analysis

Sandler O'Neill compared selected financial information for ARC to a peer group of selected publicly traded companies operating manufactured housing communities throughout the United States ("Peer Group"). The Peer Group consisted of the following four publicly traded companies:

American Land Lease, Inc.		Sun Communities, Inc.
Equity Lifestyle Properties, Inc.		UMH Properties, Inc.

The analysis compared certain financial information provided by senior management of ARC and market trading data for ARC to publicly available financial and market trading data for the Peer Group. The table below sets forth the data for ARC as of and for the twelve months ended March 31, 2007 and the data for the Peer Group as of and for the twelve months ended December 31, 2006, with pricing data as of April 13, 2007.

ARC's LTM 3/31/07 results per financial information provided by management

Estimated FY 2007 and 2008 results per ARC management budget

(1): Imputed valuations based on FFO include the addition of the net debt being retired by ARC plus the book value of ARC's preferred stock. Analysis does not assume the assumption of any debt by Farallon.

Sandler O'Neill noted the purchase price for ARC's assets to be sold to Buyer was $1.794 billion in cash and the assumption of debt, subject to adjustment.

Precedent Transaction Analysis

Sandler O'Neill analyzed 41 transactions in the manufactured housing communities industry since January 1, 2004 for which the consideration paid per homesite was publicly available. For these 41 transactions, the consideration per homesite ranged from $1,275 to $80,000 with a mean value of $24,381 and a median value of $20,776. Sandler O'Neill noted that consideration per ARC homesite in this transaction equaled approximately $31,329.

Present Value Analysis

Sandler O'Neill performed an analysis that estimated the net present value of ARC based on estimated Funds from Operations and EBITDA through December 31, 2011. Sandler O'Neill assumed ARC performed in accordance with the financial projections provided by the senior management of ARC for the years ended December 31, 2007 through 2011. The projections exclude the results of the NLASCO insurance operations.

Funds From Operations ("FFO") Multiples

To approximate the terminal value of ARC at December 31, 2011, Sandler O'Neill applied price to FFO multiples of 11.0x to 19.0x. The terminal values were then discounted to present values based on a range of discount rates of 10.0% to 14.0%. Based on an analysis of the Peer Group's cost of equity, this range was selected to reflect different assumptions regarding required rates of return for investors in the manufactured housing communities industry. For comparison purposes, the net debt being retired by ARC in this transaction (assuming no debt is assumed by Buyer) plus the book value of ARC's preferred stock was added to the discounted terminal values. In addition, ARC's terminal value at December 31, 2011 was calculated using the same range of price to FFO multiples (11.0x to 19.0x) applied to a range of discounts and premiums to management's financial projections. The range applied to the projected FFO was 20% under budget to 20% over budget, using a discount rate of 12.18% for the tabular analysis and increasing the net present value of the terminal values by the sum of the net debt being retired by ARC and the book value of ARC's preferred stock. As illustrated in the following tables, this analysis indicated an imputed valuation range for ARC of $1.410 billion to $1.805 billion when applying the price to FFO multiples to management's budget, and $1.359 billion to $1.877 billion when applying the price to FFO multiples to the -20% to +20% budget range. For purposes of rendering its opinion on April 17, 2007, Sandler O'Neill calculated a purchase price of $1.794 billion.

EBITDA Multiples

To approximate the terminal value of ARC at December 31, 2011, Sandler O'Neill applied enterprise value to EBITDA multiples of 12.0x to 20.0x. The terminal values were then discounted to present values based on a range of discount rates of 10.0% to 14.0%. Based on an analysis of the Peer

Group's cost of equity, this range was selected to reflect different assumptions regarding required rates of return for investors in the manufactured housing communities industry. In addition, ARC's terminal value at December 31, 2011 was calculated using the same range of enterprise value to EBITDA multiples (12.0x to 20.0x) applied to a range of discounts and premiums to management's financial projections. The range applied to the projected EBITDA was 20% under budget to 20% over budget, using a discount rate of 12.18% for the tabular analysis. As illustrated in the following tables, this analysis indicated an imputed valuation range for ARC of $903 million to $1.782 billion when applying the enterprise value to EBITDA multiples to management's budget, and $779 billion to $1.948 billion when applying the enterprise value to EBITDA multiples to the -20% to +20% budget range. For purposes of rendering its opinion on April 17, 2007, Sandler O'Neill calculated a purchase price of $1.794 billion.

Note: Dollars in Millions

In connection with its analyses, Sandler O'Neill considered and discussed with ARC's board how the present value analyses would be affected by changes in the underlying assumptions, including variations with respect to estimated FFO and EBITDA. Sandler O'Neill noted that the discounted cash flow analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Miscellaneous

ARC has agreed to pay Sandler O'Neill a fee of $500,000 in connection with rendering a fairness opinion in this transaction. The entire amount of the fee is payable at the earlier of the closing of the transaction and December 31, 2007. ARC has also agreed to reimburse certain of Sandler O'Neill's reasonable out-of-pocket expenses incurred in connection with its engagement and to indemnify Sandler O'Neill and its affiliates and their respective partners, directors, officers, employees, agents, and controlling persons against certain expenses and liabilities, including potential liabilities under the securities laws.

In the ordinary course of its respective broker and dealer businesses, Sandler O'Neill may purchase securities from and sell securities to ARC and their affiliates. Sandler O'Neill may also actively trade the debt and/or equity securities of ARC or their affiliates for its own accounts and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

Vote Required to Approve the Asset Sale and the Transaction Agreement and Other Proposals; Stockholder Support Agreement

The asset sale cannot be completed unless, among other things, it is approved by the affirmative vote of holders of shares of our common stock and special voting stock entitled to cast at least a majority of all votes entitled to be cast on the matter at our special meeting, voting as a single class. An adjournment or postponement of the special meeting cannot occur unless it is approved by the affirmative vote of a majority of the votes cast at our special meeting. Only holders of record of our common stock and special voting stock will be entitled to vote at the special meeting. If we fail to obtain the requisite vote for the asset sale proposal, we will not be able to consummate the asset sale and either party may terminate the Transaction Agreement. If we fail to obtain the requisite vote for the adjournment and postponement proposal, we will not be able to adjourn or postpone the special meeting, if necessary.

Nature of Our Business After the Asset Sale

After the asset sale to Buyer, we will only have the NLASCO business, the cash proceeds from the sale, retained NOLs and certain retained obligations. NLASCO is a Delaware corporation that specializes in providing fire and homeowners insurance to low value dwellings and manufactured homes primarily in Texas and other areas of the south, southeastern and southwestern United States. NLASCO operates two insurance subsidiaries, National Lloyds Insurance Company, which we refer to as NLIC, and American Summit Insurance Company, which we refer to as ASIC. NLIC is rated "A" (Excellent) by A.M. Best Company, and ASIC is rated "A" (Excellent) by A.M. Best. NLIC, chartered in 1948 and licensed in 18 states, is an insurance company on the Lloyd's plan domiciled in Texas. NLIC underwrites fire and limited homeowner's insurance through approximately 4,800 independent agents. Through approximately 1,800 independent agents and selected managing general agents, which we refer to as MGAs, ASIC offers homeowners and property and casualty insurance primarily to manufactured home owners. NLASCO's policies are typically written for actual cash value of up to $250,000 in the low value dwelling market and replacement cost of up to $125,000 in the manufactured home market. Liability on a homeowners policy typically provides coverage up to $100,000 with a maximum of $300,000 issued by a few select agents. The vast majority of NLASCO's property policies currently exclude coverage for water and mold and provide actual cash value payments as opposed to replacement costs. NLASCO has an experienced management team, a high quality agency force and an established track record of growth and underwriting profitability.

We will continue to work to maximize stockholder interests with a goal of returning value to our stockholders.

Interests of Certain Directors and Executive Officers in the Asset Sale

When considering the recommendation by our board of directors to vote for the asset sale, you should be aware that a number of our executive officers and directors have interests in the asset sale that are different from the interests of our other stockholders. Our board of directors was aware of

these interests and considered them, among other matters, in unanimously approving and adopting the Transaction Agreement and the transactions contemplated by the Transaction Agreement, including the asset sale. Such interests relate to, or arise from, among other things:

•: the fact that pursuant to their original terms of issuance, unvested ARC equity awards held by all awards holders, which are comprised of our four executive officers, two of whom are also board members, will vest upon the closing of the asset sale; and
•: the potential of certain of our executive officers to receive payments under severance agreements.

Each of these additional interests is described below, to the extent material, and, except as described below, such persons have to our knowledge no material interest in the asset sale apart from those of stockholders generally.

Severance Agreements

Each of Messrs. Kreider and Gesell has entered into a severance agreement with ARC pursuant to which he would become entitled to severance payments and other benefits in the event his employment is terminated by ARC without "cause," as defined in the severance agreements, or by the executive officer for any reason prior to a change in control and for "good reason," as defined in the severance agreements, after a change in control. We may refer to each of these circumstances as a "qualifying termination of employment." These agreements provide for severance benefits regardless of whether a "change in control" of ARC has occurred, but provide for some additional benefits if a qualifying termination of employment occurs following a change in control (as defined in the severance agreements). Consummation of the asset sale will constitute a change in control for purposes of these severance agreements. If there were to occur a qualifying termination of employment following a change in control, the severance payments and benefits that would become payable under these agreements include: (i) payment equal to the sum of the executive's then-current base salary plus the average cash bonus paid over the last three years following ARC's initial public offering in February 2004, such amount to be paid out over one year; (ii) the executive's prorated target annual bonus for the year in which the termination occurs; and (iii) the opportunity to elect continued coverage under ARC's group health plans in accordance with Section 4980B of the Internal Revenue Code, or Code, for the two-year period immediately following termination of employment, subject to reduction to the extent he receives comparable benefits from a subsequent employer. The severance agreements also contain confidentiality provisions which apply indefinitely, and non-competition and non-solicitation provisions which apply during the employment period and for a one-year period thereafter. Each of the severance agreements requires ARC to make an additional tax gross-up payment to the executive if any amounts paid or payable to the executive pursuant to his severance agreement or otherwise in connection with a change in control would be subject to the excise tax imposed on "excess parachute payments" under Section 4999 of the Code. We do not anticipate that ARC would be liable for any tax gross-up payments for change in control-related benefits in connection with the asset sale. The cash severance payments that would be payable to each of our executive officers under their respective severance agreements upon completion of the asset sale and assuming a subsequent qualifying termination of employment as of June 30, 2007, would be: to Mr. Kreider, $524,000; and to Mr. Gesell, $490,000.

Stock Options, Warrants and Restricted Stock

Each of our executive officers holds options to acquire shares of our common stock. Any stock options held by our executive officers that are not vested as of the date of this proxy statement will, in accordance with their original terms, become fully vested at the effective time of the asset sale.

As of April 26, 2007, Scott L. Gesell, Executive Vice President, General Counsel and Corporate Secretary holds a fully vested warrant to acquire 9.37 shares of ARC common stock at $15.61 per share, which warrant has an expiration date of July 23, 2010.

The following table sets forth the number of stock options to acquire our common stock held by our executive officers as of the date of this proxy statement. The "Total Cash Value" of the options is determined by multiplying (i) the excess, if any, of the book value per share after giving effect to the transaction on a pro forma basis ($12.20 per share) over the exercise price of such options by (ii) the number of shares subject to such options.

Name	Unvested Options (No. of Shares)	Weighted Average Exercise Price ($)	Weighted Average Exercise Price ($)	Total Cash Value of Options ($)
Larry D. Willard	210,000	10.77	N.A.	$	300,300
James F. Kimsey	147,000	10.77	N.A.	$	210,210
Lawrence E. Kreider	84,000	10.77	N.A.	$	120,120
Scott L. Gesell	84,000	10.77	N.A.	$	120,120

Restricted Stock

As of March 31, 2007, two of our executive officers, Mr. Kreider and Mr. Gesell, hold shares of restricted stock (2,000 shares and 4,000 shares, respectively) which will become vested at the effective time of the asset sale.

Management Incentive Plan

Under our management incentive plan, upon a change in control of ARC (as defined in the plan), the performance period outstanding at the time of a change in control will be deemed to be completed, the maximum level of performance will be deemed to have been attained and we will then be obligated to pay to each participant a pro-rata portion of each outstanding award. Assuming for this purpose that the maximum awards for our executive officers under the management incentive plan for 2007 are equal to the amount that was actually paid to our executive officers for 2006 under the management incentive plan, the following amounts would be payable upon a change in control of ARC occurring as of June 30, 2007: Larry Willard: $250,000; James Kimsey: $160,000; Larry Kreider: $107,250; and Scott Gesell: $97,500.

Continuation of Employment and Benefits

Under the Transaction Agreement, the Buyer has agreed to offer employment, effective as of the completion of the asset sale, to all of our employees who are either employed by an Acquired Company or who are providing services to an Acquired Business. The terms of the employment offers must include salary rates that are equal to their current base salaries and incentive opportunities that are no less favorable than those provided by us.

Following the completion of the asset sale:

•: for no less than 12 months, the Buyer has agreed to provide continuing employees with salary and benefits under employee benefit or similar plans (other than equity plans) that are substantially similar to those currently provided by ARC to its employees;
•: the Buyer has agreed to cause all of its employee benefit plans, programs and agreements to treat the prior service of any of our employees with us as service rendered to the Buyer, with certain limited exceptions;

•: the Buyer has agreed, and has agreed to use its commercially reasonable best efforts to cause third parties, to (1) waive certain pre-existing condition limitations, (2) honor certain pre-existing condition limitations, (3) honor certain deductibles or co-payment amounts and (4) waive certain waiting period limitations in connection with benefit arrangements;
•: the Buyer has agreed that we may award "stay bonuses" of up to an aggregate of $4 million to our employees, provided that the identity of the recipients and the amount payable to each recipient will be subject to the consent of the Buyer, although such consent may not be unreasonably withheld. Such "stay bonus" will be paid (i) 100% by Buyer in the event they relate to our employees that are employed at properties that are marketed by the Buyer in accordance with the Transaction Agreement, or (ii) 50% by Buyer and 50% by us to the extent paid to any other of our employees. Any such stay bonus will be payable by the Buyer 90 days following the closing of the asset sale and will not be paid to any ARC employee who does not accept an offer of employment by the Buyer or who terminates his/her employment with the Buyer before the end of that 90-day period; and
•: the Buyer has agreed that its tax-qualified savings plan will accept qualifying rollovers of our employees' accounts under the ARC tax-qualified savings plan.

Pursuant to the terms of the Transaction Agreement, ARC employees are not deemed to be third party beneficiaries under the terms thereof.

Tax Consequences of the Asset Sale

The following is a summary of material United States Federal income tax consequences from the asset sale. This discussion does not address any tax consequences arising under the laws of any state, local, or foreign jurisdiction.

The sale of assets by us pursuant to the Transaction Agreement will be a taxable transaction to the Sellers for United States Federal income tax purposes. Accordingly, we will recognize a gain or loss with respect to the sale of assets pursuant to the Transaction Agreement in an amount equal to the aggregate difference between the amount of the consideration received for each asset and the adjusted tax basis in the asset sold. The amount of consideration will include the amount of liabilities assumed, to the extent taken into account for United States Federal income tax purposes, by Buyer in the asset sale. Although the asset sale will result in a taxable gain to us, we believe that a substantial portion of the taxable gain will be offset by current year losses from operations and available NOLs being retained by us.

No Appraisal Rights

Although our stockholders will not experience any change in their rights as stockholders as a result of the asset sale, the Maryland General Corporation Law provides for stockholder appraisal rights in connection with the sale of substantially all of a company's assets. However, pursuant to state law, we have opted-out of such rights in our Charter. Accordingly, our stockholders will have no right to dissent and obtain payment for their shares specifically as a result of this asset sale.

Regulatory Approvals

The asset sale is not subject to review by the FTC and DOJ under the HSR Act. Nevertheless, the FTC and DOJ may choose to review the transaction, although this would not be customary. We are not aware of any other material regulatory requirements or governmental approvals or actions that may be required to consummate the asset sale, except for compliance with the applicable regulations of the SEC in connection with this proxy statement and compliance with the Maryland General Corporation Law in connection with the asset sale. Should any such approval or action be required, it is presently

contemplated that such approval or action would be sought. There can be no assurance, however, that any such approval or action, if needed, could be obtained and would not be conditioned in a manner that would cause the parties to abandon the asset sale.

Other Agreement

Concurrently with the execution of the Transaction Agreement, Farallon Capital Partners, L.P. entered into a limited guarantee in favor of the Sellers, which we refer to as the "Farallon Guarantee" pursuant to which it guaranteed, subject to the terms, conditions and limitations set forth in such limited guarantee, the due and punctual performance, when due, of (i) Buyer's obligation to pay any termination fee under the Transaction Agreement (as described under "The Transaction Agreement—Termination Fees; Expense Reimbursement") and (ii) any obligation of Buyer, up to an aggregate of $180 million, to pay damages to the guaranteed parties in respect of a claim made following termination of the Transaction Agreement, such obligation solely resulting from a willful breach of the Transaction Agreement by Buyer (it being understood that the failure of the Buyer to effect the closing as a result of the failure of the funding parties under either of the financing commitments received by Buyer in connection with the Transaction Agreement to fund the financing contemplated thereby will not be deemed a willful breach of the Transaction Agreement unless such failure resulted solely from Buyer's willful breach of its covenant in the Transaction Agreement relating to Buyer's financing of the transaction), but excluding any liability for any special, indirect, consequential or punitive damages claimed by any guaranteed party, including lost profits, loss of revenue or income, cost of capital, or loss of business reputation or opportunity.

THE TRANSACTION AGREEMENT

This section of the proxy statement contains a summary of the material provisions of the Transaction Agreement. It is not intended to provide any other factual information regarding its terms. This description does not purport to be complete and is qualified in its entirety by the full text of the Transaction Agreement attached as Annex A to this proxy statement.

Assets to be Retained by ARC

Description of Liabilities to be Assumed and Retained

Liabilities to be Assumed by Buyer

In connection with the purchase of the assets, Buyer agrees to assume liabilities of the Sellers to the extent related to the Acquired Business, our equity interests in the Acquired Companies and the Acquired Assets, other than the liabilities described below under "Description of Liabilities to be Retained by ARC":

•: Assumed Indebtedness;
•: all liabilities with respect to all pending, threatened or other actions, suits, proceedings, investigations or other claims to the extent relating to or arising from the Acquired Business or the Acquired Assets, or any asset in the Acquired Business;
•: all liabilities to the extent relating to or arising from the ownership, operation, possession or management of the Acquired Business or the Acquired Assets, or any asset in the Acquired Business, including accounts payable and trade obligations;
•: all liabilities under or in connection with any contracts included in the Acquired Assets;
•: all liabilities for any violation of law to the extent arising in connection with or related to the Acquired Business or the Acquired Assets;

•: all liabilities to the extent relating to the employment practices of the Sellers or any of their affiliates and compliance with or violations of any labor laws prior to the closing of the transaction, in each case other than liabilities related to employment discrimination;
•: all liabilities to the extent relating to the condition of the Acquired Business or the Acquired Assets or any asset in the Acquired Business or the presence of any hazardous materials on the properties to be acquired or otherwise arising under any environmental law or constituting an environmental claim to the extent related to the Acquired Business or the Acquired Assets or any asset in the Acquired Business;
•: all other liabilities to the extent resulting from, arising out of or relating to the Acquired Business, the Acquired Assets or any asset in the Acquired Business; and
•: the obligation to pay certain "stay bonuses" to certain of our employees.

Liabilities to be Retained by ARC

We will retain all liabilities not assumed by Buyer, including liabilities relating to:

•: the Retained Business;
•: Any Excluded Assets;
•: our indebtedness or the indebtedness of any of our subsidiaries (including any Acquired Company), other than Assumed Indebtedness, including liabilities related to breaches of material covenants and indebtedness related to our aircraft;
•: any equity interest in us or our subsidiaries (other than the equity interests in the Acquired Companies), and related liabilities and obligations (including fiduciary obligations of our board of directors);
•: liabilities relating to taxes for any period ending on or before the closing date;
•: our employee benefit plans and employment practices prior to closing and certain related matters;
•: liabilities of Sellers under the Transaction Agreement or any other transaction document;
•: any liability for which Buyer and certain of its affiliates are indemnified pursuant to the Transaction Agreement, to the extent so indemnified; and
•: acts or omissions of us or our subsidiaries (excluding the Acquired Companies) after the effective time of the transaction.

Prior to the closing of the transaction, we or our designated affiliates will assume, pay, discharge and perform all of the above liabilities retained by ARC. In addition, the Sellers have assumed financial responsibility for the following expenses: costs of obtaining title policies and certain endorsements related to the acquired properties, costs of a survey for each acquired property, all costs related to debt and preferred stock retained by Sellers, all costs related to the unitholders of ARC LP, and all other costs incurred in connection with obtaining our or the other Sellers' required statutory approvals and other consents.

Purchase Price

the amount realized by us is estimated to be approximately $540 million to $550 million net of retained debt and preferred stock.

Purchase Price Adjustments

The consideration paid by Buyer for the assets being acquired will be adjusted for certain prepaid items, capital expenditures, financial expenses, deposits and other liabilities, which we refer to as the "adjustment amount". Specifically, the adjustment amount is an amount equal to the following:

•: the aggregate principal amount of any tenant notes originated by Sellers or the Acquired Companies with a note date between April 17, 2007 and the closing date

increased by:

•: the sum of (x) the amount, not exceeding $5,600,000 in the aggregate, paid by Sellers or the Acquired Companies for any manufactured homes acquired between April 17, 2007 and the closing date that are included in the Acquired Assets being transferred to Buyer, and (y) the amount, not exceeding $500,000 in the aggregate, of capitalized costs related to buying, or costs incurred for selling and/or renting such acquired new homes, as of the closing date

reduced by the following to the extent applicable:

•: the amount by which (x) the aggregate amount of capital expenditures made by Sellers and the Acquired Companies in respect of the Acquired Business prior to the closing date is less than (y) the product of $9,000,000 multiplied by the quotient of the number of days elapsed in 2007 prior to the closing date divided by 365

further reduced by:

•: any "stay bonus amount", which is the amount by which the aggregate amount of stay bonuses paid to company employees pursuant to the Transaction Agreement (as described under "—Employee Matters") exceeds the sum of (a) 50% of the aggregate amount of stay bonuses paid to company employees other than company employees that are employed at properties that are marketed by Buyer pursuant to the Transaction Agreement plus (b) 100% of the aggregate amount of stay bonuses paid to company employees that are employed at properties that are marketed by Buyer pursuant to the Transaction Agreement

further reduced by:

•: the aggregate amount of Assumed Indebtedness as of the closing

and reduced by (if the following is a negative number) or increased by (if the following is a positive number):

•: an adjustment for net working capital and for certain pro rated assets and liabilities of the Acquired Business.

On the closing of the transaction, Buyer will pay to Sellers an amount equal to the purchase price reduced by certain of Seller's expenses and an estimated adjustment amount. Within 90 days after the closing of the transaction, Buyer will prepare and deliver a closing statement to Sellers setting forth Buyer's determination of the final adjustment amount. Sellers will then have 30 days to object to the calculation of the final adjustment amount. Within three days of the adjustment amount and the closing statement being finalized, if the final adjustment amount is less than the estimated adjustment amount, then Sellers will pay Buyer the difference and if the final adjustment amount is greater than the estimated adjustment amount, then Buyer will pay Sellers the difference.

Closing and Effective Time

The closing of the transaction will take place not later than the fourth business day immediately following the date on which all closing conditions have been satisfied or waived (other than those conditions that by their nature have to be satisfied at the closing date, but subject to the satisfaction or waiver of those conditions) or another time as agreed by the parties to the Transaction Agreement. If the Sellers determine that a delay of the closing date is necessary to satisfy the conditions requiring certain consents in connection with ARC LP's Senior Exchangeable Notes Due 2025, ARC LP's limited partners, and their Trust Preferred Securities Due 2035, the Sellers have a one time option to delay the closing date to a date that is no more than 45 days following the date on which the Sellers would otherwise have been required to effect the closing (but in no event later than December 31, 2007). The transactions contemplated by the Transaction Agreement will become effective upon the effective time, which is the time at which the closing occurs.

Change in Transaction Structure

If Buyer determines it would be beneficial to transfer one or more of the acquired properties from its current owner at the closing to an entity designated by Buyer, Sellers have agreed to cooperate with Buyer in effecting such transfer, provided no such transfer (i) has the effect of increasing the obligations or reducing the rights of Sellers under the Transaction Agreement or increasing the costs and expenses of Sellers, (ii) is reasonably expected to impede or delay the consummation of the transactions contemplated under the Transaction Agreement, or (iii) will constitute a waiver of any condition to the transactions contemplated under the Transaction Agreement.

Delayed Acquired Assets

To the extent that the transfer or assignment from any Seller to Buyer of any Acquired Asset or equity interest in an Acquired Company would be a violation of applicable law with respect to such Acquired Asset or Acquired Company or otherwise adversely affect the rights of the transferee as a result of the failure to obtain or make any consent, approval, waiver, authorization, notice or filing required to be made in connection with the transactions contemplated by the Transaction Agreement, other than any consent, approval, waiver, authorization, notice or filing in respect of assumed indebtedness, then the transfer or assignment to Buyer of such asset or interest (which we refer to as a "Delayed Acquired Asset"), will be automatically deemed deferred and any purported transfer or assignment will be null and void until such time as all legal impediments are removed and/or any required authorizations have been made or obtained; provided, however, that the closing of the transaction will otherwise take place in all respects as provided for in the Transaction Agreement and the initial purchase price will not be reduced.

If, at the closing date, there exist any Delayed Acquired Assets, the applicable Seller will hold such asset for the use and benefit of Buyer, insofar as reasonably possible. To the extent not prohibited by law, such Seller will take such actions as may be reasonably requested by Buyer in order to place Buyer in the same position as if such Delayed Acquired Asset had been transferred as contemplated in the Transaction Agreement. To the extent permitted by law, Buyer will be entitled to the management of any Delayed Acquired Assets not yet transferred to it.

If and when the consent or authorization is obtained, the transfer of the applicable asset or interest to Buyer will automatically and without further action be effected in accordance with the terms of the Transaction Agreement.

of the Transaction Agreement and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating the terms of the Transaction Agreement. Moreover, certain representations and warranties were made as of a specified date, may be subject to a contractual standard of materiality different from what may be viewed as material to stockholders, or may have been used for the purpose of allocating risk between the parties rather than establishing matters as facts. For the foregoing reasons, you should not rely on the representations and warranties as statements of factual information.

A "company material adverse effect" means an event, fact, circumstance or effect that results in or causes a material adverse change in the business, assets, liabilities or financial condition of the Acquired Companies and the Acquired Business, taken as a whole, except to the extent such material adverse change results from or is caused by:

•: the negotiation, announcement, execution, delivery, consummation or pendency of the Transaction Agreement or the transactions contemplated thereby.

Regulatory Approvals

Each party agrees to cooperate to obtain all required statutory approvals, including any filings under the HSR Act and to satisfy any conditions imposed by any governmental entity in all final orders. The parties agree to respond promptly to any inquiries or requests received from any governmental entity for additional information or documentation and not enter into any agreement

with any governmental entity that would reasonably be expected to adversely affect the parties' ability to consummate the transactions contemplated by the Transaction Agreement. The parties agree to provide each other with copies of all filings made with, and inform one another of any communications received from, any governmental entity in connection with the Transaction Agreement.

Commercially Reasonable Efforts

Each party agrees to use its respective commercially reasonably efforts to take all actions and to do all things necessary to consummate the transactions contemplated by the Transaction Agreement, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents, and to obtain all consents and authorizations. From April 17, 2007 and until the receipt of our stockholder approval, we will not issue equity securities of any class in an amount equal to or more than five percent (5%) of the number of outstanding equity securities of such class to any person or any group (as defined under Rule 13d-5 under the Exchange Act) unless such person or group concurrently therewith executes an agreement in favor of Buyer that is substantially identical to the support agreement.

Access

We agree to provide Buyer reasonable access to each Acquired Company's properties, offices, plants and other facilities, books and records, and agree to furnish Buyer with such financial, operating and other data as Buyer may reasonably request. The parties agree to retain for a period of seven years the books and records relating to the Acquired Business relating to periods prior to the closing of the transaction and agree to afford each other reasonable access during normal business hours, to such books and records. Moreover, prior to the closing of the transaction, Buyer will be permitted to market, hold open for sale or otherwise discuss with other parties the sale or other disposition of certain properties, some of which require our consent.

No Solicitation

We agree that we will not, and that we will not permit our affiliates or our affiliates' officers, directors, employees, agents or representatives, including any investment banker, attorney or accountant retained by them, to, directly or indirectly:

•: initiate, solicit, knowingly encourage or facilitate any inquiries, proposals or offers with respect to, or the making or completion of, an alternative proposal;
•: engage or participate in any negotiations or discussions concerning, or provide or cause to be provided any non-public information or data relating to us, the Acquired Companies or the Acquired Business in connection with, or have discussions with any person relating to, an actual or proposed alternative proposal, or otherwise knowingly encourage or facilitate any effort or attempt to make or implement an alternative proposal;
•: approve, endorse or recommend, or propose publicly to approve, endorse or recommend, any alternative proposal;
•: approve, endorse or recommend, or propose to approve, endorse or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to any alternative proposal;
•: amend, terminate, waive or fail to enforce, or grant any consent under, any confidentiality, standstill or similar agreement; or

•: resolve to propose or agree to do any of the foregoing; provided, however, it is understood and agreed that any determination or action by our board of directors permitted in connection with a superior proposal will not be deemed to be a breach or violation of the no solicitation covenant in the Transaction Agreement.

We will and will cause each of our subsidiaries to, and will direct each of our representatives to, immediately cease any existing solicitations, discussions or negotiations with any person that has made or indicated an intention to make an alternative proposal.

We may, at any time prior to obtaining our stockholder approval, in response to a bona fide unsolicited, written alternative proposal made after April 17, 2007 and which did not result from or arise in connection with a breach of the no solicitation covenant in the Transaction Agreement and which our board of directors determines, in good faith, after consultation with its outside counsel and financial advisors, may reasonably be expected to lead to a superior proposal:

•: furnish non-public information with respect to us and our subsidiaries to the person making such alternative proposal and its representatives pursuant to a customary confidentiality agreement no less restrictive of the other party than the confidentiality agreement between us and Farallon Capital Management, L.L.C., dated March 8, 2007; and
•: participate in discussions or negotiations with such person and its representatives regarding such alternative proposal;

provided, however, (i) that the Buyer will be entitled to receive an executed copy of such confidentiality agreement prior to or substantially simultaneously with us furnishing information to the person making such alternative proposal or its representatives, and (ii) that we shall simultaneously provide or make available to the Buyer any non-public information concerning us that is provided to the person making such alternative proposal or its representatives which was not previously provided or made available to the Buyer.

Neither our board of directors nor any committee thereof will:

•: withdraw or modify in a manner adverse to Buyer or publicly propose to withdraw or modify in a manner adverse to the Buyer, the recommendation to our stockholders of the approval of the transactions contemplated by the Transaction Agreement or approve or recommend, or publicly propose to approve, endorse or recommend, any alternative proposal (which we refer to as a "change in recommendation"); or
•: approve any letter of intent, agreement in principle, acquisition agreement or similar agreement relating to any alternative proposal.

Notwithstanding the foregoing, our board of directors may, at any time prior to obtaining our stockholders' approval, in response to a bona fide, unsolicited, written alternative proposal made after April 17, 2007, and which did not result from or arise in connection with a breach of the no solicitation covenant in the Transaction Agreement and which our board of directors determines, in good faith, after consultation with its outside counsel and financial advisors, constitutes a superior proposal, make a change in recommendation or terminate the Transaction Agreement pursuant to the termination and abandonment section under the Transaction Agreement; provided, that our board of directors will not be entitled to exercise its right to make a change in recommendation or terminate the Transaction Agreement pursuant to the termination and abandonment section under the Transaction Agreement unless we have (A) complied in all respects with the no solicitation covenant in the Transaction Agreement, (B) provided to Buyer four business days' prior written notice advising Buyer that our board of directors intends to take such action and specifying the reasons for such action, including the material terms and conditions of any superior proposal (it being understood that any material amendment to the financial terms or any other material term of any such superior proposal will require

a new notice to Buyer advising of a superior proposal and an additional three business day notice period), (C) provided to Buyer all materials and information delivered or made available to the person or group of persons making any superior proposal in connection with such superior proposal, (D) during such four business day period (or three business day period in the case of an amendment), if requested by Buyer, engaged in good faith negotiations with Buyer to propose amendments to the Transaction Agreement such that any alternative proposal which was determined to constitute a superior proposal is no longer deemed to be a superior proposal, and (E) if at the end of such four business day period (or three business day period in the case of an amendment), such alternative proposal has not been withdrawn and continues to constitute a superior proposal (after giving effect to any amendments to the Transaction Agreement that may be proposed by Buyer following a notice of superior proposal, as a result of the negotiations required by (D) above or otherwise) then we promptly (and in any event within 24 hours) will advise Buyer orally and in writing of:

•: any alternative proposal or indication or inquiry with respect to or that would reasonably be expected to lead to any alternative proposal;
•: any request for non-public information relating to us or our subsidiaries that is reasonably expected to be related to an alternative proposal; and
•: any inquiry or request for discussion or negotiation regarding an alternative proposal, including, in each case, the identity of the person making any such alternative proposal or indication or inquiry and the material terms of any such alternative proposal or indication or inquiry (including copies of any document or correspondence evidencing such alternative proposal or inquiry). We will keep Buyer reasonably informed on a reasonably current basis of the status (including any material change to the terms thereof) of any such alternative proposal or indication or inquiry.

As used herein, "alternative proposal" means any inquiry, proposal or offer from any person or group of persons other than Buyer or one of its affiliates for (i) a merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, asset sale or purchase, dissolution or similar transaction involving us (or any of our subsidiaries whose businesses or assets account for 20% or more of our and our subsidiaries', taken as a whole, net revenues, net income or assets), (ii) any proposal for our issuance of 20% or more of any class of our equity interests or (iii) any proposal or offer to acquire in any manner, directly or indirectly, 20% or more of any class of our equity interests or of our and our subsidiaries' consolidated total assets, in each case other than the transactions contemplated by the Transaction Agreement.

As used herein, "superior proposal" means any bona fide offer made by a third party that, if consummated, would result in such person (or its stockholders) owning, directly or indirectly, more than 50% of our common stock then outstanding (or of the equity interests of the surviving entity in a merger or the ultimate parent of the surviving entity in a merger), or all or substantially all of the Acquired Assets, which our board of directors reasonably determines (after consultation with its legal advisors and its financial advisors), taking into account all financial, legal, regulatory and other aspects of such proposal and the person making the proposal, (i) to be (A) more favorable to our stockholders than the transactions contemplated by the Transaction Agreement after taking into account the then outstanding proposal of Buyer (including any amendments to the Transaction Agreement proposed by Buyer pursuant to the no solicitation section under the Transaction Agreement or otherwise) and (B) reasonably capable of being completed on the terms set forth in the proposal and (ii) for which financing, to the extent required, is then committed or reasonably likely to be obtained.

Subject to the terms and conditions set forth in the Transaction Agreement, Buyer grants to Sellers a limited, non-exclusive, non-sublicensable, royalty free and non-transferable right and license to use any of Sellers' trademarks and logos in connection with the Retained Business for a period of one hundred and twenty (120) days following the closing of the transaction, after which Sellers will cease all further use of any such trademarks and logos and destroy any and all material bearing such trademarks and logos.

•: the occurrence of any casualty, condemnation or other event at any one or more acquired properties will not relieve Buyer of its obligations under the Transaction Agreement, provided, however, that at the closing of the transaction Sellers will assign to Buyer any and all claims and proceeds Sellers may have with respect to any casualty insurance policies or condemnation awards with respect to any acquired property which related to a casualty or condemnation occurring after the date of the Transaction Agreement but prior to the closing of the transaction, and Buyer will have the right to proceed against any insurance company or condemning authority to recover any such items and will have the right prior to the closing of the transaction to participate in all negotiations and discussions regarding the adjustment and settlement of any insurance claims or claims for condemnation procedures with respect to any property or group of properties having a value in excess of $500,000;

Employee Matters

Buyer agrees to offer employment to each individual who is employed by an Acquired Company or any Seller or any of their subsidiaries in connection with the Acquired Business (who we refer to as a

"company employee") not later than 10 days prior to the expected closing date, which offer shall be subject to the closing occurring. The terms of Buyer's employment offers will include (a) a rate of base salary or wages equal to at least 100% of the rate of base salary or wages in effect immediately prior to the closing of the transaction and (b) amounts of cash incentive opportunities that are no less favorable than those in effect immediately prior to the closing of the transaction. Buyer will offer employee benefits that are substantially similar in the aggregate to those provided to company employees immediately prior to the closing of the transaction.

The employment of all employees who accept Buyer's offer of employment will be deemed to have occurred with no interruption or break in service and no termination of employment. Buyer also agrees not to fire or otherwise discharge any employees who accept Buyer's employment offer other than for cause until 45 days after the closing of the transaction. We and the other Sellers remain solely liable (including with respect to severance costs and related liabilities) for any company employee who does not accept Buyer's offer of employment, and Buyer will have no liability with respect to any such employee. We agree to use reasonable efforts to encourage the company employees to accept Buyer's offers of employment.

We agree to provide personnel information with respect to each company employee as may be reasonably requested by Buyer, provided it is not in violation of any law regarding the use and disclosure of personal information.

We may award "stay bonuses" of up to an aggregate of $4 million to help retain our employees, which bonuses would be paid by Buyer, provided that the identity of the recipients and the amount payable to each recipient will be subject to the consent of Buyer. Such stay bonuses will not be payable by Buyer to any company employee who does not accept Buyer's offer of employment or who terminates his or her employment with Buyer prior to 90 days following the closing of the transaction. The "stay bonus" will be paid (i) 100% by Buyer in the event they relate to our employees that are employed at properties that are marketed by the Buyer in accordance with the Transaction Agreement, or (ii) 50% by Buyer and 50% by us to the extent paid to any other of our employees.

On or before the closing of the transaction, we agree to provide a list of the company employees who have experienced or will experience an employment loss or layoff within 90 days prior to the closing of the transaction.

Tax Matters

Sellers and Buyer have agreed that the purchase price will be allocated among the Acquired Assets in a manner to be determined by Buyer in consultation with the Sellers, based on the advice or recommendation of a nationally recognized appraisal firm, and that the Sellers and Buyer will use the allocations so determined for all tax purposes. Sellers will assume liability for and will pay all sales, transfer, stamp and similar taxes imposed on the sale of the Acquired Companies and Acquired Assets, and will file all required tax returns due in connection with such taxes.

Sellers have agreed to indemnify Buyer against all pre-closing taxes, and also against taxes of the Acquired Companies arising from the transaction (including transfer taxes and taxes on gains of the Sellers). Sellers have also agreed to indemnify Buyer against any breach of representations and warranties of the Sellers relating to taxes. The tax matters portion of the Transaction Agreement, including the indemnification provisions relating to taxes, will survive indefinitely (or, in the case of tax representations and warranties, until 60 days following the expiration of the applicable statute of limitations, unless notice for indemnification is given within the applicable survival period, in which case until the claim is finally resolved). Sellers are responsible for defending any audit, litigation or other proceeding, or portion thereof, with respect to any taxes for which Sellers are wholly responsible for payment, and have the authority to negotiate, compromise and settle any such tax proceeding, provided, that Sellers obtain the written consent of Buyer if such compromise would have an adverse

effect on the Buyer (after giving effect to the Sellers' indemnification obligations) or would otherwise adversely affect the tax liabilities of the Acquired Companies for any period after the closing of the transaction.

In the event of termination of the Transaction Agreement, the obligations of Buyer and Sellers will terminate (except for the confidentiality agreement and the provisions relating to brokers and finders fees, fees and expenses, termination, termination fees, definitions and certain general provisions such as survival of certain provisions, notices, binding effect, assignment, amendments, interpretation, severability, governing law and venue), and there will be no other liability on the part of the Sellers or the Buyer to the other except liability arising out of any willful breach of any of the representations, warranties or covenants in the Transaction Agreement or as provided for in the Farallon Guarantee.

•: if (i) an alternative proposal that reasonably appears to be a bona fide proposal is made known to us or directly to our stockholders or any person shall have publicly announced an intention (whether or not conditional or withdrawn) to make an alternative proposal that reasonably appears to be bona fide and thereafter (ii) the Transaction Agreement is terminated by either us or Buyer because stockholder approval was not obtained or by us if the transaction had not closed by the end date (in each case, other than a termination giving rise to a right of Buyer to receive the termination fee in the event described above), then we will pay to Buyer the Buyer Expenses;
•: if, following the termination of the Transaction Agreement giving rise to an obligation of us to pay the Buyer Expenses pursuant to the situation described immediately above, we enter into a definitive agreement with respect to, or consummate, a transaction contemplated by any alternative proposal (provided that the references to "20%" in the definition of alternative proposal will be deemed to be references to "50%") within twelve months of the termination date, then we will pay to Buyer the termination fee; and

Transaction Agreement and conditions that, by their nature, are to be satisfied at closing and which were, at the time of termination, capable of being satisfied), then:

•: if, at the time of such termination, the lender under Buyer's debt financing commitment has failed to fund the debt financing contemplated by such commitment, Buyer will pay us a termination fee of $37.5 million; or
•: if, at the time of such termination, the financing party under Buyer's third party equity commitment has failed to fund the equity financing contemplated by such commitment, Buyer will pay us a termination fee of $50 million;

provided that, if both termination fees are due, then only the equity commitment termination fee will be due.

Our right to receive payment of the Buyer termination fee pursuant to the Transaction Agreement or the guarantee thereof pursuant to the Farallon Guarantee, will be the exclusive remedy of us against Buyer, Farallon Capital Partners, L.P. or any of their respective stockholders, partners, members, directors, affiliates, officers or agents for the loss suffered as a result of the failure of the transaction to be consummated and any other losses, damages, obligations or liabilities suffered as a result of or under the Transaction Agreement. Except as set forth in the termination fees provision of the Transaction Agreement, neither Buyer nor its related parties or other representatives, will have any further liability or obligation relating to or arising out of the Transaction Agreement.

Similarly, Buyer's right to receive payment of the termination fee pursuant to the termination fees provision of the Transaction Agreement will be the exclusive remedy of the Buyer against Sellers, the Acquired Companies or any of their respective stockholders, partners, members, directors, affiliates, officers or agents for the loss suffered as a result of the failure of the transaction to be consummated and any other losses, damages, obligations or liabilities suffered as a result of or under the Transaction Agreement. Except with respect to payment of the termination fee in accordance with the termination fees provision of the Transaction Agreement, neither the Sellers, the Acquired Companies nor any of their related parties or other representatives will have any further liability or obligation relating to or arising out of the Transaction Agreement.

Notwithstanding the foregoing, and except as provided in and subject to the limitations of, the Farallon Guarantee, the payment of any termination fees or expenses of Buyer under the termination fees section of the Transaction Agreement will not relieve any party of liability for willful breach of any of the representations, warranties, covenants or agreements in the Transaction Agreement.

Recent Events

In January 2007, we acquired the common stock of NLASCO

On January 31, 2007, we acquired all of the stock of NLASCO, a privately held property and casualty insurance holding company. In exchange for the stock, NLASCO's stockholders, consisting of C. Clifton Robinson and affiliates, received $105.75 million in cash and 1,218,880 shares of our common stock for a total consideration of $117.5 million. In addition, Flexpoint Fund, L.P., a fund managed by Flexpoint Partners, LLC of Chicago, Illinois, invested $20 million to purchase 2,154,763 shares of our common stock at the leading ten-day average market price of our common stock on the date the agreement was signed, subject to certain anti-dilution provisions. The acquisition closed on January 31, 2007.

In order to raise $80 million to provide a source of funding for a portion of the acquisition of NLASCO, we also conducted a rights offering to our stockholders. In the rights offering, all holders of our common stock as of the record date of December 19, 2006 received one non-transferable right to purchase 0.242 shares of our common stock for each share held. The price at which the additional shares were offered for purchase was $8.00 per share. Gerald J. Ford, one of our directors and the beneficial owner of approximately 16.0% of our common stock through an affiliate, Hunter's Glen/Ford, Ltd., backstopped the rights offering, meaning they agreed to purchase all shares of common stock that remained unsubscribed for in the rights offering (other than those beneficially acquired by Mr. Ford in a private placement) and purchased 391,549 shares that were not purchased in the rights offering by the stockholders of record on the record date, at the rights offering price per share of $8.00. Mr. Ford, directly and through an affiliate, ARC Diamond, LP, agreed to purchase in a private

placement the full number of shares of our common stock that they would otherwise have been entitled to subscribe for in the rights offering at $8.00 per share, thereby acquiring an additional 1,759,400 shares of our common stock pursuant to this private placement. Currently, Mr. Ford is deemed to be the beneficial owner of 9,421,642 shares of our common stock.

In addition, Flexpoint Fund, L.P., a fund managed by Flexpoint Partners, LLC of Chicago, Illinois, invested $20 million to purchase our common stock at the leading ten-day average market price of our common stock on the date the agreement was signed, subject to certain anti-dilution provisions. Mr. Ford is a limited partner of Flexpoint Fund, L.P., which is managed by Flexpoint Partners, LLC. As a limited partner, Mr. Ford is pari passu with all other limited partners and has no financial interest in, or management authority of, its managing general partner.

C. Clifton Robinson relationship with ARC

In furtherance of the terms of the stock purchase agreement dated October 6, 2006, or the NLASCO Agreement, C. Clifton Robinson, Chairman of NLASCO and a member of our board of directors, entered into certain ancillary agreements with us including, but not limited to, an employment agreement, a non-competition agreement, a lock up agreement, and a registration rights agreement.

In conjunction with the closing of the NLASCO acquisition, NLASCO entered into an employment agreement with C. Clifton Robinson that provides he will serve as chairman of NLASCO and will be paid $100,000 a year. In addition, NLASCO entered into an employment agreement with Mr. Robinson's son, Gordon B. Robinson, the former vice chairman and deputy chief executive officer of NLASCO, pursuant to which he will serve in an advisory capacity to NLASCO and for which he will be paid $100,000 per year.

Each employment agreement will be for a one-year term with automatic one-year extensions by agreement of the parties. The employment agreements also include non-competition and non-solicitation provisions similar to that in the non-competition agreement discussed below, but with a term until two years after the termination of employment. Further, each of the Robinsons entered into a non-competition agreement pursuant to which he has agreed not to, directly or indirectly, engage or invest in, own, manage, operate, finance, control, or participate in the ownership, management, operation, financing, or control of, be employed by, lend credit to, or render services to any business whose products, services or activities compete with those of NLASCO or any of its subsidiaries within certain states. Each non-competition agreement also includes customary non-solicitation provisions. The term of the non-competition agreements is five years. Lastly, C. Clifton Robinson executed a share lock-up agreement pursuant to which he has agreed not to offer, sell, contract to sell, hypothecate, pledge, sell or grant any option, right or warrant to purchase, or otherwise dispose of, or contract to dispose of, our common stock until 20 months after the closing date of the NLASCO acquisition. Upon the closing of the NLASCO acquisition in January 2007, NLASCO became a wholly owned subsidiary of us.

In connection with the closing of our acquisition of NLASCO, and the issuance of shares of our common stock to Mr. Robinson, as described above, on January 31, 2007, we entered into a Registration Rights Agreement (the "Robinson Registration Rights Agreement") with Mr. Robinson pursuant to which we agreed to prepare and file with the SEC, within 18 months after the date of the Robinson Registration Rights Agreement, a registration statement with respect to the resale of the 1,218,880 shares of our common stock issued to Mr. Robinson.

Mr. Robinson was appointed to our board of directors in March 2007 pursuant to the terms of the NLASCO Agreement and is standing for election to our board at this year's annual meeting.

We redeemed the OP's preferred partnership units

In January 2007, all 705,688 units of the OP's Series "C" preferred partnership units were redeemed according to their terms for 1,628,410 shares of our common stock.

We granted stock options to four senior executive officers

On July 27, 2006, the compensation committee of our board of directors approved the grant of 500,000 non-qualified stock option awards to four of our senior executive officers pursuant to our 2003 equity incentive plan at an exercise price of $10.74 per share, the closing price of our common stock on the NYSE on the date of grant. The options have a term of ten years from the date of the award. Under the terms of the grants, the options vest ratably over a three-year period with the first third of the award amount vesting on the first anniversary of the award, the second third vesting on the second anniversary date of the award, and the balance vesting on the third anniversary date of the award. Vesting is accelerated in certain circumstances, including in the event of the death of the award recipient or in the event of a change of control, as defined in the plan.

On March 8, 2007, the Compensation Committee of our board of directors approved the grant of 25,000 non-qualified stock option awards to four of our senior executive officers pursuant to our 2003 Equity Incentive Plan at the exercise price of $11.28 per share, the closing price of our common stock on the NYSE on the date of grant. The options have a term through July 27, 2016. Under the terms of the grants, the options vest ratably over a 3 year period with the first third vesting on July 27, 2007, the second third vesting on July 27, 2008 and the last third vesting on July 27, 2009.

The consummation of the transactions contemplated by the Transaction Agreement would constitute a change in control pursuant to the terms of the benefit plan under which stock options were granted.

We amended our charter

At a special meeting of stockholders held on January 23, 2007, our stockholders approved an amendment to our charter, which set limitations on levels of stock ownership. As a result of the actions taken at the meeting on January 23, 2007, our board of directors amended the rights plan by providing that if the rights were not exercised by January 24, 2007, they were no longer exercisable. No rights were exercised as of January 24, 2007. The accumulated NOLs that precipitated the Rights Plan will be retained by us upon the consummation of the assets sale.

We had modifications to our debt agreements

On July 11, 2006, six indirect wholly owned subsidiaries of the Operating Partnership, as co-borrowers, entered into a $230 million mortgage debt facility with Merrill Lynch Mortgage Lending, Inc. Approximately $175 million of the proceeds of the loan were used to repay other debt. The loan agreement is comprised of two components; a $170 million 10-year fixed rate mortgage debt component and a $60 million 3-year floating rate mortgage debt component with two one-year (no-fee) extension options. The fixed rate component bears interest at 6.239% and requires interest-only payments for the term of the loan. The floating rate component is adjusted monthly, bears interest at one-month LIBOR plus 80 basis points and requires interest-only payments for the term of the loan. The loan is secured by 59 manufactured housing communities located in 18 states as well as an assignment of leases and rents associated with the mortgaged property. The loan is non-recourse with the exception that the repayment of the indebtedness is guaranteed by the Operating Partnership pursuant to a guaranty of non-recourse obligations in the event of declaration of bankruptcy, interference with any of the lenders rights, and asset transfers and other activities in violation of the loan documents. Under the provisions of the loan agreement, we have the right to prepay any portion of the floating rate component, with or without release of the mortgaged property, without penalty.

Subsequent to a prepayment of the entire floating rate component of the loan, we have the option to prepay a fixed portion of the loan subject to prepayment fees, yield maintenance or defeasance in accordance with the terms of the loan agreement. Subject to the terms and conditions of the Transaction Agreement, obligations associated with the debt facility are subject to assumption by Buyer upon closing of the transaction.

Our board of directors authorized the sale of three communities and we closed on 40 contracted community sales

During 2006, our board of directors authorized the sale of three communities in addition to the 38 contracted for sale in 2005. We closed on 40 of these community sales transactions comprising $85.4 million of cash proceeds net of related debt, defeasance and other closing costs of $75.0 million. We expect to close one remaining sales transaction in 2007. There can be no assurance, however, that we will close the remaining community sale, or, if it closes, that it will close on the terms set forth in its contract.

Employees

Our employees are all employed by our management services subsidiary and perform various property management, maintenance, acquisition, renovation and management functions. As of March 31, 2007, our management services subsidiary had 901 full-time equivalent employees.

Properties

As of March 31, 2007, our portfolio consisted of 275 manufactured home communities comprising 57,264 homesites located in 23 states, generally oriented toward all-age living.

As of December 31, 2006, our communities had an occupancy rate of 82.4%. Leases for homeowners are generally month-to-month, or in limited cases year-to-year, and require security deposits. In the case of our residents renting homes from us, lease terms are typically one year, and require a security deposit. Under our lease with option to purchase program, historically residents have entered into leases with a twelve to sixty month term, pursuant to which they pay a security deposit and option fee and commit to monthly payments creditable to their down payment upon purchase of the home. In the agreement, we commit to the price that the resident will pay for the purchase of the home at the end of the lease.

Legal Proceedings

We are a party to various legal actions resulting from our operating activities. These actions consist of litigation and administrative proceedings arising in the ordinary course of business, some of which are covered by liability insurance, and none of which is expected to have a material adverse effect on our consolidated financial condition, results of operations or cash flows taken as a whole.

STOCKHOLDER PROPOSALS

Stockholder proposals intended to be presented at our 2008 annual meeting of stockholders pursuant to Rule 14a-8 under the Exchange Act must be received by us at our principal executive offices no later than 5:00 p.m., local time, on January 1, 2008 and must otherwise comply with the requirements of Rule 14a-8 in order to be considered for inclusion in the 2008 proxy statement and proxy.

1.14 Delayed Acquisition Assets.

(a) Subject to Section 7.2(g), if and to the extent that the transfer or assignment from any Seller to Buyer of any Acquired Asset or any Acquired Company Interest would be a violation of applicable Law with respect to such Acquired Asset or Acquired Company Interest or otherwise adversely affect the rights of the transferee thereunder as a result of the failure to obtain or make any consent, approval, waiver, authorization, notice or filing required to be made in connection with the transactions contemplated by this Agreement, other than any consent, approval, waiver, authorization, notice or filing in respect of Assumed Indebtedness (to which this Section 1.14 shall not apply), then the transfer or assignment to Buyer of such Acquired Asset or Acquired Company Interest (each, a "Delayed Acquired Asset") shall be automatically deemed deferred and any such purported transfer or assignment shall be null and void until such time as all legal impediments are removed and/or any required authorizations have been made or obtained, but the Closing shall otherwise take place in all respects as provided for in this Agreement and the Initial Purchase Price shall not be reduced.

(b) If the transfer or assignment of any Acquired Asset or Acquired Company Interest intended to be transferred or assigned hereunder is not consummated at the Closing as a result of such Acquired Asset or Acquired Company Interest being a Delayed Acquired Asset, then the applicable Seller shall thereafter, directly or indirectly, hold such Delayed Acquired Asset for the

A-8

use and benefit of Buyer (at the expense of Buyer), insofar as reasonably possible. In addition, to the extent not prohibited by Law, such Seller shall take or cause to be taken such other actions as may be reasonably requested by Buyer in order to place Buyer, insofar as reasonably possible, in the same position as if such Delayed Acquired Asset had been transferred as contemplated hereby and so that all the benefits and burdens relating to such Delayed Acquired Asset, including possession, use, risk of loss, potential for gain, and dominion, control and command over such Delayed Acquired Asset, are to inure from and after the Closing to Buyer. To the extent permitted by Law and to the extent otherwise permissible in light of any required consent or authorization, Buyer shall be entitled to, and shall be responsible for, the management of any Delayed Acquired Assets not yet transferred to it as a result of this Section 1.14 and the parties hereto agree to use commercially reasonable efforts to cooperate and coordinate with respect thereto.

(c) If and when the consent or authorization, the absence of which caused the deferral of transfer of any Acquired Asset or Acquired Company Interest pursuant to this Section 1.14 is obtained, the transfer of the applicable Acquired Asset or Acquired Company Interest to Buyer shall automatically and without further action be effected in accordance with the terms of this Agreement and the applicable Transaction Documents.

(d) Prior to the Closing Date, the Sellers shall deliver to Buyer a list identifying, in reasonable detail, to the Knowledge of the Sellers, the Delayed Acquired Assets and the authorizations required therefore (provided that this provision shall be disregarded for purposes of Section 7.2(a) and Article IX).

(e) The parties hereto further agree that, assuming as set forth in Section 1.14(b) that all or substantially all of the benefits and burdens relating to the Acquired Assets inure to Buyer, (i) any Delayed Acquired Assets referred to in this Section 1.14(e) shall be treated for all income Tax purposes as Assets of Buyer and (ii) neither Buyer nor Seller shall take, and each of Buyer and Seller shall prevent any of their respective Affiliates from taking, any position inconsistent with such treatment for any income Tax purposes (unless required by a change in applicable income Tax Law or a good faith resolution of a contest).

A-30

Business Day period (or three Business Day period in the case of an amendment), such Alternative Proposal has not been withdrawn and continues to constitute a Superior Proposal (after giving effect to any amendments to this Agreement that may be proposed by the Buyer following a Notice of Superior Proposal, as a result of the negotiations required by clause (D) or otherwise).

If at any time prior to the Effective Time, any information should be discovered by any Party hereto which should be set forth in an amendment or supplement to the Proxy Statement so that the Proxy Statement would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Party which discovers such information shall promptly notify the other Parties hereto and, to the extent required by applicable Law, an appropriate amendment or supplement describing such information shall be promptly filed by ARC with the SEC and disseminated by ARC to the stockholders of ARC. No filing of, or amendment or supplement to, the Proxy Statement will be made by ARC (including documents incorporated by reference therein) without providing the Buyer a reasonable opportunity to review and comment thereon; provided that with respect to documents that are incorporated by reference in the Proxy Statement, this right to review and comment shall apply only with respect to information relating to this Agreement or the transactions contemplated hereby or to Buyer or its Affiliates.

A-32

Company Employee so reports to employment.

The Buyer shall not fire or otherwise discharge any Continuing Employees other than for cause until 45 days after the Closing Date.

(ii) On and as of the Closing Date, the Sellers shall provide such additional personnel information with respect to each Company Employee as may be reasonably requested by the Buyer; provided, however, that Sellers shall not be required to provide any information to the Buyer, the transmission of which would violate any Law regarding the transmission of personnel data, including the applicable provisions of the Health Insurance Portability Accountability Act of 1996, the Personal Information Protection and Electronic Documents Act and other legislation regulating the collection, use and disclosure of personal information, each as amended and the regulations promulgated thereunder.

(iii) The Sellers shall remain solely liable (including with respect to any severance costs and related liabilities) for any Company Employee who does not become a Continuing Employee and shall be solely liable with respect to an Inactive Employee for the period until such employee becomes a Continuing Employee, and the Buyer shall have no liability with respect to any such employee.

Each Continuing Employee who is a participant in the Sellers Savings Plan shall be given the opportunity to receive a distribution of his or her account balance and shall be given the opportunity to elect a "direct rollover" in accordance with Section 401(a)(31) of the Code of the participant's such account balance to the Buyer's Savings Plan, subject to and in accordance with the provisions of such plan and applicable Law.

Any such Stay Bonus shall be payable by the Buyer upon the completion of 90 days following the Closing and shall not be paid to any Company Employee who does not accept an offer of employment by the Buyer or who terminates such Company Employee's employment with the Buyer prior to 90 days following the Closing.

A-45

after written notice thereof is given by ARC to the Buyer or one (1) Business Day prior the End Date; provided that the Sellers are not then in breach of this Agreement such that any of the conditions set forth in Section 7.2(a) or 7.2(b) would not be capable of being satisfied prior to the End Date;

(ii) if all the conditions set forth in Sections 7.1 and 7.2 have been satisfied (other than any condition the failure of which to be satisfied has been proximately caused by the breach of this Agreement by the Buyer and conditions that, by their nature, are to be satisfied at Closing and which were, at the time of termination, capable of being satisfied) and the Buyer has failed to fulfill its obligation and agreement herein to consummate the Closing within five (5) Business Days following written notice of such satisfaction from ARC; or

(iii) since the date hereto there shall have been a Company Material Adverse Effect that is continuing and cannot be cured by the End Date.

In the event of termination of this Agreement pursuant to this Section 8.1, this Agreement shall terminate (except for the Confidentiality Agreement and the provisions of Sections 3.15, 4.7, 5.9, this Section 8.1, Section 8.2, Article X and Article XI), and there shall be no other liability on the part of the Sellers or the Buyer to the other except liability arising out of any willful breach of any of the representations, warranties or covenants in this Agreement or as provided for in the Farallon Guarantee, in which case the aggrieved Party shall be entitled to all rights and remedies available at Law or in equity.

8.2 Termination Fees.

(a) (i) If this Agreement is terminated (x) by ARC pursuant to Section 8.1(c)(iii) or (y) by the Buyer pursuant to Section 8.1(d)(ii) or, following a Change in Recommendation, pursuant to any other provision of Section 8.1, then in any such event described in clause (x) or (y), ARC shall pay to the Buyer a termination fee of $20 million in cash (the "Termination Fee") plus an amount equal to all of the fees and expenses of the Buyer, its contemplated transaction partners and its and their Representatives, including fees and expenses of financial advisors, outside legal counsel, accountants, experts and consultants, incurred by the Buyer, its contemplated transaction partners and its and their Representatives in connection with the authorization, preparation, negotiation,

A-46

execution or performance of this Agreement and the transactions contemplated hereby, up to a maximum of $5 million (the "Buyer Expenses").

(ii) If (A) an Alternative Proposal that reasonably appears to be bona fide shall have been made known to ARC or shall have been made directly to its stockholders generally or any Person shall have publicly announced an intention (whether or not conditional or withdrawn) to make an Alternative Proposal that reasonably appears to be bona fide and thereafter and (B) this Agreement is terminated (x) by ARC or the Buyer pursuant to Section 8.1(b)(iii) (so long as the Alternative Proposal was publicly disclosed and not withdrawn at the time of ARC Stockholder Meeting) or (y) by ARC pursuant to Section 8.1(b)(i) (in each case, other than a termination giving rise to a right of Buyer to receive the Termination Fee pursuant to Section 8.2(a)(i)), then ARC shall pay to the Buyer the Buyer Expenses.

(iii) If, following a termination of this Agreement giving rise to an obligation of ARC to pay the Buyer Expenses pursuant to Section 8.2(a)(ii), ARC enters into a definitive agreement with respect to, or consummates, a transaction contemplated by any Alternative Proposal (provided that for purposes of this Section 8.2(a)(iii), the references to "20%" in the definition of Alternative Proposal shall be deemed to be references to "50%") within twelve (12) months of the date this Agreement is terminated, then ARC will pay to the Buyer the Termination Fee.

(iv) For the avoidance of doubt, in no event shall ARC be required to pay the Termination Fee on more than one occasion.

(b) If this Agreement is terminated by ARC pursuant to Section 8.1(b)(i), Section 8.1(c)(i) or Section 8.1(c)(ii) and, at the time of termination, all the conditions set forth in Section 7.1 and 7.2 have been satisfied (other than any condition the failure of which to be satisfied has been proximately caused by the breach of this Agreement by the Buyer and conditions that, by their nature, are to be satisfied at Closing and which were, at the time of termination, capable of being satisfied), then:

(i) if, at the time of such termination, the lender under the Debt Financing Commitment has failed to fund the Debt Financing contemplated thereby, the Buyer shall pay to ARC a termination fee of $37.5 million (the "Debt Event Buyer Termination Fee"); or

(ii) if, at the time of such termination, the financing party under the Third Party Equity Commitment has failed to fund the Equity Financing contemplated thereby, the Buyer shall pay to ARC a termination fee of $50 million (the "Equity Event Buyer Termination Fee" and each of the Equity Event Buyer Termination Fee and the Debt Event Buyer Termination Fee being referred to as the "Buyer Termination Fee").

(iii) For the avoidance of doubt, in no event shall the Buyer be required to pay both the Equity Event Buyer Termination Fee and the Debt Event Buyer Termination Fee or to pay a Buyer Termination Fee on more than one occasion, but if both the Equity Event Buyer Termination Fee and the Debt Event Buyer Termination Fee are due, then only the Equity Event Buyer Termination Fee shall be due.

(c) Any payment required to be made pursuant to Section 8.2(a)(iii) shall be made to the Buyer promptly following the earlier of the execution of a definitive agreement with respect to, or the consummation of, any transaction contemplated by an Alternative Proposal (and in any event not later than two Business Days after delivery to ARC of notice of demand for payment); any payment required to be made pursuant to Section 8.2(a)(i) or 8.2(a)(ii) shall be made to the Buyer promptly following the termination of this Agreement giving rise to such right to payment (and in any event not later than two Business Days after delivery to ARC of notice of demand for

A-47

payment), and such payment shall be made by wire transfer of immediately available funds to an account to be designated by the Buyer. In circumstances in which Buyer Expenses are payable, such payment shall be made to the Buyer not later than two Business Days after delivery to ARC of an itemization setting forth in reasonable detail all Buyer Expenses (which itemization may be supplemented and updated from time to time by the Buyer until the 60th day after the Buyer delivers such notice of demand for payment), and all such payments shall be made by wire transfer of immediately available funds to an account to be designated by the Buyer. Any payment required to be made pursuant to Section 8.2(b) shall be made to ARC promptly following the termination of this Agreement by ARC giving rise to such right to payment (and in any event not later than two Business Days after delivery to the Buyer of notice of demand for payment), and such payment shall be made by wire transfer of immediately available funds to an account to be designated by ARC.

(d) In the event that ARC shall fail to pay the Termination Fee and/or Buyer Expenses, or the Buyer shall fail to pay the Buyer Termination Fee, required pursuant to this Section 8.2 when due, such fee and/or Buyer Expenses, as the case may be, shall accrue interest for the period commencing on the date such fee and/or Buyer Expenses, as the case may be, became past due, at a rate equal to the rate of interest publicly announced by Citibank, in the City of New York from time to time during such period, as such bank's Prime Lending Rate (the "Prime Rate"). In addition, if either Party shall fail to pay such fee and/or Buyer Expenses, as the case may be, when due, the such owing Party shall also pay to the owed Party all of the owed Party's costs and expenses (including attorneys' fees) in connection with efforts to collect such fee and/or Buyer Expenses, as the case may be, the Buyer and ARC acknowledges that the fees, Buyer Expense reimbursement and the other provisions of this Section 8.2 are an integral part of the Transaction and that, without these agreements, the Buyer and the Sellers would not enter into this Agreement.

(e) Each of the Parties hereto acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement and that none of the Termination Fee, the Buyer Termination Fee or the Buyer Expenses is a penalty, but rather is liquidated damages in a reasonable amount that will compensate the Buyer or ARC, as the case may be, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. Notwithstanding anything to the contrary in this Agreement, but subject to the last sentence of this Section 8.2(e): (i) ARC's right to receive payment of the Buyer Termination Fee pursuant to this Section 8.2 or the guarantee thereof pursuant to the Farallon Guarantee shall be the exclusive remedy of ARC against the Buyer, the Farallon Guarantor or any of their respective stockholders, partners, members, directors, Affiliates, officers or agents for (x) the loss suffered as a result of the failure of the Transaction to be consummated and (y) any other losses, damages, obligations or liabilities suffered as a result of or under this Agreement and the transactions contemplated hereby, and except with respect to payment of the Buyer Termination Fee in accordance with this Section 8.2, except as set forth in Section 8.2(d), neither the Buyer nor its stockholders, partners, members, directors, officers or agents, as the case may be, shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by hereby (except that the Buyer also shall be obligated with respect to the provisions of this Section 8.2, it being understood that no other Person shall have any liability or obligation under or with respect to such provisions); and (ii) Buyer's right to receive payment of the Termination Fee pursuant to this Section 8.2 shall be the exclusive remedy of the Buyer against the Sellers, the Acquired Companies or any of their respective stockholders, partners, members, directors, Affiliates, officers or agents for (x) the loss suffered as a result of the failure of the Transaction to be consummated and (y) any other losses, damages, obligations or liabilities

A-48

suffered as a result of or under this Agreement and the transactions contemplated hereby, and except with respect to payment of he Termination Fee in accordance with this Section 8.2, except as set forth in Section 8.2(d), neither the Sellers, the Acquired Companies nor any of their Affiliates, stockholders, partners, members, directors, officers or agents, as the case may be, shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby (except that the Sellers also shall be obligated with respect to the provisions of this Section 8.2, it being understood that no other Person shall have any liability or obligation under or with respect to such provisions). Notwithstanding the foregoing, and except as provided in, and subject to the limitations of, the Farallon Guarantee, the payment of the Termination Fee, the Buyer Termination Fee or the Buyer Expenses will not relieve any party hereto of liability for willful breach of any of the representations, warranties, covenants or agreements in this Agreement.

ARTICLE IX

INDEMNIFICATION

9.1 Indemnification by Sellers. From and after the Closing and subject to the provisions of this Article IX and Section 11.1, the Sellers jointly and severally agree to indemnify, defend and hold harmless the Buyer Indemnified Parties from and against any and all Liabilities, demands, claims, suits, actions, or causes of action, losses, costs, expenses, damages and judgments, whether or not resulting from third party claims, (including reasonable fees and expenses of attorneys and accountants and costs of investigation) (collectively, "Damages") incurred by any Buyer Indemnified Party and arising out of, relating to or resulting from (a) the failure of any representation or warranty set forth in Section 3.6 (Absence of Undisclosed Liabilities; Special Purpose Entities) (disregarding any materiality qualifier set forth in Section 3.6(a)) or 3.9 (Employee Benefit Plans; ERISA) to be true and correct as of the Effective Time with the same effect as though such representations and warranties had been made on and as of such time (except to the extent any such representation and warranty expressly speaks only as of a specific date, in which case as of such earlier date), (b) the failure of any representation or warranty set forth in Section 3.1(b), 3.1(c), 3.16(a) or 3.16(c) to be true and correct as of the Effective Time with the same effect as though such representations and warranties had been made on and as of such time (except to the extent any such representation and warranty expressly speaks only as of a specific date, in which case as of such earlier date), (c) any breach of any covenant or agreement of any Seller set forth in Article I or of any covenant or agreement of any Seller set forth in this Agreement that contemplates or provides for any rights, obligations or actions of any Party after the Closing or (d) any Excluded Liability.

9.2 Indemnification by the Buyer. From and after the Closing and subject to the provisions of this Article IX and Section 11.1, the Buyer agrees to indemnify, defend and hold harmless the Seller Indemnified Parties, from and against any and all Damages incurred by any Seller Indemnified Party arising out of, relating to, or resulting from (a) any breach of any covenant or agreement of the Buyer set forth in Article I or of any covenant or agreement of the Buyer set forth in this Agreement that contemplates or provides for any rights, obligations or actions of any Party after the Closing, (b) any Assumed Liability or (c) the business and operation of the Acquired Assets, the Acquired Companies and the Acquired Business, whether arising out of or relating to conduct occurring prior to, on or after the Closing, other than items for which indemnification is or would be provided by the Sellers under this Agreement.

A-49

9.3 Indemnification Process.

(a) A party making a claim for indemnification under this Article IX shall be, for the purposes of this Agreement, referred to as an "Indemnified Party" and a party against whom such claims are asserted under this Article IX shall be, for the purposes of this Agreement, referred to as an "Indemnifying Party." All claims by any Indemnified Party under this Article IX shall be asserted and resolved as follows:

(b) In the event that (i) any action, application, suit, demand, claim or legal, administrative, arbitration or other alternative dispute resolution proceeding, hearing or investigation (each, a "Proceeding") is asserted or instituted by any Person other than the Parties or their Affiliates which could give rise to Damages for which an Indemnifying Party could be liable to an Indemnified Party under this Agreement (such Proceeding, a "Third Party Claim") or (ii) any Indemnified Party under this Agreement shall have a claim to be indemnified by any Indemnifying Party under this Agreement which does not involve a Third Party Claim (such claim, a "Direct Claim" and, together with Third Party Claims, "Claims"), the Indemnified Party shall, promptly after it becomes aware of a Third Party Claim, or determines that there exists a reasonable basis for a Direct Claim, send to the Indemnifying Party a written notice specifying the nature of such Claim and the amount or estimated amount thereof (which amount or estimated amount shall be made without prejudice to the parties' rights and shall not be conclusive of the final amount, if any, of such Claim) (a "Claim Notice"), together with copies of all notices and documents (including court papers) served on or received by the Indemnified Party in the case of a Third Party Claim, provided that a delay in notifying the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article IX except to the extent of any incremental damage or liability the Indemnifying Party shall have incurred as a result of such failure to give such notice, in which case the Indemnifying Party shall be relieved of its obligations under this Article IX to the extent of such incremental damage or liability.

(c) In the event of a Third Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim and be entitled to appoint counsel of the Indemnifying Party's choice (but reasonably acceptable to the Indemnified Party) at the expense of the Indemnifying Party to represent the Indemnified Party in connection with such Proceeding; provided that the Indemnifying Party shall not be entitled to assume or continue control of the defense of any Third Party Claim if (i) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (ii) the Third Party Claim seeks an injunction or equitable relief against any Indemnified Party, (iii) the Third Party Claim, if determined in favor of the claimant, would result in Damages in excess of the amounts available for indemnification pursuant to this Article IX or (iv) the Indemnified Party has not, prior to the assumption of such defense, acknowledged that such Third Party Claim is subject to indemnification under this Article IX. If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party may retain separate counsel in connection with such Third Party Claim, but the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel only if (i) the use of counsel selected by the Indemnifying Party to represent the Indemnified Party would present such counsel with a conflict of interest or (ii) the Indemnifying Party shall not have engaged counsel to represent the Indemnified Party within a reasonable time after notice of the institution of such Third Party Claim. Nothing in this Section 9.3(c) shall require the Indemnifying Party to be responsible for the fees and expenses of more than one counsel (in addition to any local counsel) at any time in connection with the defense against a Third Party Claim. If requested by the Indemnifying Party, the Indemnified Party agrees to reasonably cooperate with the Indemnifying Party and its counsel in defending and contesting any Proceeding which the Indemnifying Party defends, or, if appropriate and related to the Proceeding in question, in making any counterclaim against the person asserting the Third Party Claim, or any

A-50

cross-complaint against any Person. No Third Party Claim may be settled or compromised (i) by the Indemnified Party without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed) or (ii) by the Indemnifying Party without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed), unless, in the case of this clause (ii), the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and such settlement provides for a full release of all Liability of the Indemnified Party in respect of such Third Party Claim; provided that, in no event will the Indemnifying Party be permitted to settle any Third Party Claim for which the Indemnifying Party would not be entitled to assume the defense hereunder, without the prior written consent of the Indemnified Party. In the event any Indemnified Party settles or compromises or consents to the entry of any judgment with respect to any Third Party Claim without the prior written consent of the Indemnifying Party (except in the event the Indemnifying Party unreasonably withheld or delayed its consent), such Indemnified Party shall be deemed to have waived all rights against the Indemnifying Party for indemnification under this Article IX with respect to such Third Party Claim.

9.4 Limitations on Claims.

(a) Liability Threshold for Buyer Indemnified Parties. Notwithstanding anything in this Article IX to the contrary, no Buyer Indemnified Party shall be entitled to indemnification pursuant to Section 9.1(a), unless and until the aggregate amount of Damages incurred by such party for which indemnification is available under Section 9.1(a), exceeds an amount equal to $10,000,000 (the "Liability Threshold"), and then, subject to Section 9.4(b), the Buyer Indemnified Parties shall be entitled to the benefit of the indemnity under Section 9.1(a) only for the portion of any and all Damages that exceed the Liability Threshold.

(b) Maximum Liability. Notwithstanding anything in this Article IX to the contrary, the aggregate amount of the Sellers' liability pursuant to Section 9.1(a) shall not exceed $100,000,000.

(i) The amount of any Damages incurred by the Indemnified Party shall be reduced by the net amount the Indemnified Party or any of its Affiliates recovers (after deducting all attorneys' fees, expenses and other costs of recovery) from any insurer or other party liable for such Damages (other than any Seller). The Indemnified Party shall use commercially reasonable efforts to effect any such recovery.

(ii) Any liability for indemnification under this Agreement shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement.

(d) Exclusive Remedy. Except to the extent provided in Article VI, from and after the Closing, the indemnities provided for in this Article IX shall be the exclusive remedies of the Parties and their respective officers, directors, employees, Affiliates, agents, representatives, successors and assigns for money damages in respect of any breach of or inaccuracy in any representation or warranty or breach of or noncompliance with any covenant or agreement contained in this Agreement and the Parties shall not be entitled to a rescission of this Agreement or to any further indemnification or other rights or claims for money damages in respect thereof, all of which the Parties hereto hereby waive; provided, however, that the foregoing shall not limit the right of any party to assert a claim based on fraud.

9.5 Characterization of Indemnification Payments. The Buyer and the Sellers agree to treat any indemnification payment made under this Agreement, to the maximum extent permitted by applicable Law, as an adjustment to the Final Purchase Price.

A-51

9.6 Limitation on Damages. No Party shall, under any circumstance, except to the extent imposed by any Third Party Claim, have any liability to any other Party for any special, indirect, consequential or punitive damages claimed by such other Party under the terms of or due to any breach or non-performance of this Agreement, including lost profits, loss of revenue or income, cost of capital, or loss of business reputation or opportunity.

9.7 No Other Indemnification. For the avoidance of doubt, no Party shall have any indemnification obligations to any other party in respect of this Agreement or the transactions contemplated hereby except as set for in Section 6.1, Section 9.1 or Section 9.2 of this Agreement.

Items disclosed on one particular section of the Sellers Disclosure Letter or the Buyer Disclosure Letter relating to one section of this Agreement shall be deemed to be constructively disclosed or listed in other sections of the Sellers Disclosure Letter or the Buyer Disclosure Letter, as the case may be, relating to other sections of this Agreement only to the extent it is reasonably apparent on the face of such other sections of the Sellers Disclosure Letter or the Buyer Disclosure Letter that such disclosure is applicable to such other sections of the Sellers Disclosure Letter or the Buyer Disclosure Letter, as the case may be. The fact that any item of information is contained in any disclosure letter shall not be construed as an admission of liability under any applicable Law, or to mean that such information is required to be disclosed in or by this Agreement, or to mean that such information is Material. Such information shall not be used as a basis for interpreting the term "Material," "material," "materially," "materiality," "Company Material Adverse Effect," or any similar qualification in this Agreement.

11.8 Severability. Any term or provision of this Agreement that is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, the Parties agree that the court making such determination, to the greatest extent legally permissible, shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.

("Salmaho" and, together with ARC, ARC LP, ARC Dealership, Windstar, ARC IV, ARCMS and ARC TRS, the "Sellers") and American Riverside Communities LLC (the "Buyer"), have entered into transaction agreement, dated as of April 17, 2007 (the "Agreement") pursuant to which each of the Sellers, either directly or through certain of their subsidiaries, will transfer their respective right, title and interest in certain assets, and the Buyer will assume certain liabilities, related to the operation of manufactured homes communities, the sale, rental and financing of manufactured homes (the "Acquired Assets") and other related businesses (the "Acquired Company Interests") to the Buyer (the "Transaction"). The aggregate cash consideration to be paid by the Buyer in respect of the purchase of the Acquired Company Interests and the Acquired Assets will be $1,794,000,000 (the "Purchase Price"), subject to certain adjustments as set forth in the Agreement. Capitalized terms used herein without definition shall have the meanings assigned to them in the Agreement. The other terms and conditions of the Transaction are more fully set forth in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Purchase Price to ARC.

Sandler O'Neill & Partners, L.P., as part of its investment banking business, is regularly engaged in the valuation of companies, businesses and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed, among other things: (i) the Agreement; (ii) certain publicly available financial statements and other historical financial information of ARC that we deemed relevant; (iii) internal financial projections for ARC, which did not include NLASCO Inc., for the years ending December 31, 2007 through 2011 as furnished by and reviewed with senior management of ARC; (iv) certain publicly available research estimates of valuation metrics and the future financial performance of ARC and other companies we deemed to be reasonably comparable to ARC; (v) the financial terms of other business combinations in the manufactured home communities industries of which we were aware; (vi) the current market environment generally and the manufactured home communities industry; and (vii) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the senior management of ARC the business, financial condition, results of operations and prospects of ARC, including management's assumptions regarding the future revenue streams, costs, cash flow and earnings of the Acquired Assets and the Acquired Company Interests.

C-1

In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by ARC or the Buyer and their representatives or that was otherwise reviewed by us and we have assumed such accuracy and completeness for purposes of rendering this opinion. We have further relied on the assurances of the senior management of ARC that they are not aware of any facts or circumstances regarding ARC or the Acquired Assets or the Acquired Company Interests that would make any of such information inaccurate or misleading. We have not been asked to undertake, and have not undertaken, an independent verification of any of such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of ARC, the Acquired Assets or the Acquired Company Interests or any of their subsidiaries, or the collectibility of any such assets, nor have we been furnished with any such evaluations or appraisals.

With respect to the financial projections for ARC used by Sandler O'Neill in its analyses, the senior management of ARC confirmed to us that those projections and estimates (including any assumptions related to such projections and estimates) reflected the best currently available estimates and judgments of the future financial performances and revenue streams of ARC, the Acquired Assets and the Acquired Company Interests. We assumed that the financial performances reflected in all projections and estimates used by us in our analyses would be achieved. We express no opinion as to such financial projections or estimates or the assumptions on which they are based. We have also assumed that there has been no material change in the assets, financial condition, results of operations, business or prospects of ARC, the Acquired Assets or the Acquired Company Interests since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analysis that ARC, the Acquired Assets and the Acquired Company Interests would remain as a going concern for all periods relevant to our analyses, that all material representations and warranties of ARC or each of the Sellers contained in the Agreement and all related agreements are true and correct, that each party to the agreements will perform all of the covenants required to be performed by such party under the agreements and that the conditions precedent in the agreements will not be waived. Finally, with your consent, we have relied upon the advice ARC has obtained from their legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Transaction and the other transactions contemplated by the Agreement.

Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof.

We will receive a fee for rendering this opinion. ARC has also agreed to indemnify us against certain liabilities arising out of our engagement. As we have advised you, in the past we have provided certain investment banking services to ARC for which we have received compensation. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to ARC and its affiliates. We may also actively trade the equity and/or debt securities of ARC and/or its affiliates for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. We express no opinion as to the the price at which ARC's common stock may trade at any time.

Our opinion is directed to the Board of Directors of ARC in connection with its consideration of the Transaction and is directed only to the fairness, from a financial point of view, of the Purchase Price to ARC. Our opinion does not address the underlying business decision of ARC to engage in the sale of the Acquired Assets and the Acquired Company Interests, the determination of the future income streams of the Acquired Assets and the Acquired Company Interests, the process undertaken to

C-2

sell the Acquired Assets and the Acquired Company Interests, the relative merits of the sale of the Acquired Assets or the Acquired Company Interests as compared to any other alternative business strategies that might exist for ARC, or the effect of any other transaction in which ARC might engage. Our opinion is not to be quoted or referred to, in whole or in part, in any registration statement, prospectus, proxy statement or other document, nor shall this opinion be used for any other purposes, without Sandler O'Neill's prior written consent.

Based upon and subject to the foregoing, it is our opinion, as of the date hereof, that the Purchase Price is fair to ARC from a financial point of view.

		Very truly yours,

(1): Loss and loss adjustment expense ratio is the ratio (expressed as a percentage) of losses and loss adjustment expenses to net premiums earned. This is a basic measurement of underwriting profitability.
(2): The underwriting expense ratio is the ratio (expressed as a percentage) of policy acquisition and other underwriting expenses, as adjusted, to net earned premiums. This is a measurement of management's relative efficiency in administering its operations. We adjust policy acquisition and other underwriting expenses by (a) other revenue that represents fee income and (b) interest expense included in underwriting expenses.
(3): The combined ratio is the sum of the loss ratio and the expense ratio. If the combined ratio is at or above 100%, an insurance company generally cannot be profitable without sufficient investment income.

AFFORDABLE RESIDENTIAL COMMUNITIES INC.
UNAUDITED PRO FORMA COMBINED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS

The following unaudited pro forma condensed consolidated financial information of Affordable Residential Communities Inc., includes historical financial information contained within our filed 10-Q and 10-K, incorporated herein by reference.

Our pro forma condensed consolidated statements of operations for the three months ended March 31, 2007 and the year ended December 31, 2006 reflect adjustments to our historical financial data to give effect to (i) the acquisition of NLASCO and related purchase transactions, (ii) the sale of the manufactured home communities business, and (iii) the related repayment of other indebtedness and payment of other costs, as if each had occurred as of January 1, 2006. Our pro forma condensed consolidated statements of operations for the years ended December 31, 2005 and 2004 reflect adjustments to our historical financial data to give effect to the sale of the manufactured communities business as if it had occurred on January 1, 2004. Pro forma results incorporate only continuing operations.

The historical financial information of ARC for the years ended December 31, 2006, 2005 and 2004 is substantially representative of the financial results of the manufactured home communities business to be sold to the Buyer because the acquisition of NLASCO, a property and casualty insurance business which is being retained by ARC, did not occur until January 2007. We have included in Annex D the financial statements of the manufactured home communities business for the quarterly period ended March 31, 2007 that exclude the financial results of NLASCO. After the sale of the manufactured home communities business the Senior Exchangeable Notes due 2025 and the Series A Preferred Stock will remain with ARC. The business to be sold encompasses the combined interest of ARC's common stockholders and OP Unitholders, whose interests are treated as minority interests in the consolidated financial statements.

We have based our unaudited pro forma adjustments upon available information and assumptions that we consider reasonable. Our unaudited pro forma condensed consolidated financial information is not necessarily indicative of what our actual financial position or results of operations would have been as of the date and for the periods indicated, nor does it purport to represent our future financial position or results of operations.

You should read our unaudited pro forma condensed consolidated financial information, together with the notes thereto, in conjunction with the more detailed information contained in our financial statements and related notes included in this proxy statement or incorporated by reference herein.

The historical financial information of ARC for the years ended December 31, 2006, 2005 and 2004 is substantially representative of the financial results of the manufactured home communities business to be sold to the Buyer because the acquisition of NLASCO, a property and casualty insurance business which is being retained by ARC, did not occur until January 2007. We have included the financial statements of the manufactured home communities business for the quarterly period ended March 31, 2007 that exclude the financial results of NLASCO. After the sale of the manufactured home communities business the Senior Exchangeable Notes due 2025 and the Series A Preferred Stock will remain with ARC. The business to be sold encompasses the combined interests of ARC's common stockholders and OP Unitholders, whose interests are treated as minority interests in the consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. Business, Basis of Presentation and Summary of Significant Accounting Policies

Business

ARC Manufactured Home Communities Business, or ARC MH or the Business, represents the manufactured home communities business of Affordable Residential Communities Inc, or ARC that is intended to be sold or otherwise liquidated in a transaction with an affilitate of Farallon Capital Management LLC, or the Buyer. ARC MH is engaged in the acquisition, renovation, repositioning and operation of all-age manufactured home communities, the retail sale and financing of manufactured homes, the rental of manufactured homes and other related businesses, all exclusively to residents in our communities.

As of March 31, 2007, ARC MH owned and operated 275 communities consisting of 57,264 homesites in 23 states with occupancy of 82.7%. Our five largest markets are Dallas-Fort Worth, Texas, with 12.5% of our total homesites; Atlanta, Georgia, with 8.7% of our total homesites; Salt Lake City, Utah, with 6.6% of our total homesites; the Front Range of Colorado, with 5.7% of our total homesites; and Kansas City-Lawrence-Topeka, with 4.3% of our total homesites. Our insurance operations are headquartered in Waco, Texas.

ARC's common stock is traded on the New York Stock Exchange under the symbol "ARC". ARC had no public trading history prior to February 12, 2004.

Basis of Presentation

The financial statements of ARC MH for the quarterly period ended March 31, 2007 have been prepared from the financial statements and accounting records of ARC. The financial statements were prepared using ARC's historical basis in the assets and liabilities of ARC MH. The financial statements include all the revenues, costs, assets and liabilities directly attributable to ARC MH and exclude amounts directly related to the insurance business of ARC which was acquired in January 2007.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America and in conformity with the rules and regulations of the Securities and Exchange Commission requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amount of revenues and expenses during the reporting period. Actual results may differ from previously estimated amounts.

The interim consolidated financial statements presented herein reflect all adjustments that are necessary to fairly present the financial position, results of operations and cash flows of the Company, and all such adjustments are of a normal and recurring nature. The results of operations for the interim period ended March 31, 2007 are not indicative of the results that may be expected for the year ended December 31, 2007. These financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2006.

The accompanying consolidated financial statements include all of our accounts, which include the results of operations of the manufactured home communities acquired only for the periods subsequent to the date of acquisition. We have eliminated all significant inter-company balances and transactions.

We have reclassified certain prior period amounts to conform to the current year presentation.

D-27

Summary of Significant Accounting Policies

Rental and Other Property

We carry rental property at cost, less accumulated depreciation. We capitalize significant renovations and improvements that extend the useful life of assets and depreciate them over their estimated remaining useful lives. We expense maintenance and repairs as incurred. Depreciation is computed primarily using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of the various classes of rental property assets are as follows:

Asset Class		Estimated Useful Lives (Years)
Manufactured home communities and improvements		10 to 30
Buildings		10 to 20
Rental homes		10 or rent-to-own term
Furniture and other equipment		5
Computer software and hardware		3

We evaluate the recoverability of our investment in rental property whenever events or changes in circumstances indicate that the recoverability of the net book value of the asset is questionable. Our assessment of the recoverability of rental property includes, but is not limited to, recent operating results and expected net operating cash flows from future operations. In the event that facts and circumstances indicate that the carrying amount of rental property may be impaired, we perform an evaluation of recoverability in which we compare the estimated future undiscounted cash flows associated with the asset to the asset's carrying amount to determine if an impairment adjustment is required. If this review indicates that the asset's carrying amount will not be fully recoverable, we will reduce the carrying value of the asset to its estimated fair value. We recorded no impairment charges during the three months ended March 31, 2007 and 2006.

Other Indefinite Lived Intangible Assets

Included in finite lived intangible assets are lease intangibles and other customer relationships of $5.1 million related to ARC MH's manufactured home communities.

Fair Value of Financial Instruments

The fair value of our debt was approximately $1,070.3 million and $1,057.3 million at March 31, 2007 and December 31, 2006, respectively. The fair value of our other financial instruments approximates their carrying value at March 31, 2007 and December 31, 2006.

Minority Interest

At March 31, 2007 and December 31, 2006, minority interest consisted of 1,493,497 and 1,455,615 OP Units of ARC, respectively, and 705,688 Series C Preferred Partnership Units ("PPU's") of ARC at December 31, 2006. The PPU's were redeemed in January 2007 for 1,628,410 shares of ARC common stock and, as a result, we decreased minority interest and increased invested capital in January 2007 by $17.6 million. Other changes to minority interest consist primarily of amounts recorded in the Statement of Operations.

D-28

Income Taxes

The ARC MH financials reflect a tax provision based on its association with ARC, an entity subject to Federal income taxes. ARC MH did not have aggregate income tax benefits or expense for the three months ended March 31, 2007. For the three months ended March 31, 2006, we allocated income taxes between continuing and discontinued operations in accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes ("SFAS No. 109"), particularly paragraph 140. We recognize income tax benefits in continuing operations on the effective rate method and income tax expense in discontinued operations without such pro-ration in accordance with Accounting Principles Bulletin 28, Interim Financial Reporting ("APB 28") and FASB Interpretations 18, Accounting for Income Taxes in Interim Periods—An interpretation of APB Opinion No. 28 ("FIN 18").

Recent Statements of Financial Accounting Standards

In September 2006, the FASB issued SFAS No.157, Fair Value Measurement ("SFAS No. 157"), which addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under GAAP. SFAS No. 157 provides a common definition of fair value to be used throughout GAAP. The FASB believes that the new standard will make the measurement of fair value more consistent and comparable and improve disclosures about those measures. SFAS No. 157 is effective for companies with fiscal years beginning after November 15, 2007 and we are still evaluating its impact on our financial position and results of operations.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities—including an amendment of FAS 115 ("SFAS No. 159"). SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS No. 159 is expected to expand the use of fair value measurement, which is consistent with the ARC Board of Directors' long-term measurement objectives for accounting for financial instruments. SFAS No. 159 is effective for companies with fiscal years beginning after November 15, 2007. Early adoption is permitted provided we also elect to apply the provisions of SFAS No. 157. We are still evaluating the impact that SFAS No. 159 will have on our financial position, results of operations and cash flows.

The Senior Fixed Rate Mortgage due 2012 bears interest at a fixed rate of 7.35% per annum, is amortized based on a 30-year schedule and matures on May 1, 2012. Pursuant to the terms of the mortgage agreement, we have established reserves relating to the mortgaged properties for real estate taxes, insurance, capital spending and property operating expenditures. The Senior Fixed Rate Mortgage due 2012 contains customary defeasance-based prepayment penalties for repayments made prior to maturity.

Senior Fixed Rate Mortgage Due 2014

We entered into the Senior Fixed Rate Mortgage due 2014 on February 18, 2004 in connection with the completion of our IPO and the Hometown acquisition. It is an obligation of certain real property subsidiaries of the OP and is collateralized by 43 manufactured home communities owned by these subsidiaries. The Senior Fixed Rate Mortgage due 2014 bears interest at a fixed rate of 5.53% per annum, is amortized based on a 30-year schedule and matures on March 1, 2014. Pursuant to the terms of the mortgage agreement, we have established reserves relating to the mortgaged properties for real estate taxes, insurance, capital spending and property operating expenditures. The Senior Fixed Rate Mortgage due 2014 contains customary defeasance-based prepayment penalties for repayments made prior to maturity.

Senior Fixed Rate Mortgage Due 2016; Senior Variable Rate Mortgage Due 2009 (repaid and terminated Senior Variable Rate Mortgage Due 2007 and Revolving Credit Mortgage Facility)

On July 11, 2006, we entered into a $230 million mortgage debt facility. Approximately $116.8 million of the proceeds were used to repay and terminate our Senior Variable Rate Mortgage and approximately $58.8 million of the proceeds were used to repay and terminate our Revolving Credit Mortgage Facility. The Loan Agreement is comprised of two components (collectively, the "Loan"): a $170 million 10-year fixed rate mortgage debt component and a $60 million 3-year floating rate mortgage debt component with two one-year (no-fee) extension options. The fixed rate component bears interest at 6.239% and requires interest-only payments for the term of the loan. The floating rate component is adjusted monthly, bears interest at one-month LIBOR plus 80 basis points (6.12% at March 31, 2007 and capped at 7.3%) and requires interest-only payments for the term of the loan. The loan is secured by 59 manufactured housing communities located in 18 states as well as an assignment of leases and rents associated with the mortgaged property. The loan is non-recourse with the exception that the repayment of the indebtedness is guaranteed by the OP pursuant to a guaranty of non-recourse obligations in the event of declaration of bankruptcy; interference with any of the lenders rights, and asset transfers and other activities in violation of the loan documents. Under the provisions of the loan agreement, we have the right to prepay any portion of the floating rate component, with or without release of the mortgaged property, without penalty. Subsequent to a prepayment of the entire floating rate component of the loan, we have the option to prepay a fixed portion of the loan subject to prepayment fees, yield maintenance or defeasance in accordance with the terms of the loan agreement.

Various Individual Fixed Rate Mortgages

We have assumed various individual fixed rate mortgages in connection with the acquisition of various properties that were encumbered at the time of acquisition as follows:

a): Mortgages assumed as part of individual property purchases. These notes total approximately $34.1 million at March 31, 2007, mature from 2007 through 2028 and have an average effective interest rate of 7.23%. These mortgages are secured by 11 specific manufactured home communities.
b): Mortgages assumed in conjunction with the Hometown acquisition. These notes total approximately $66.7 million, mature from 2008 through 2031 and carry an average effective interest rate of 7.12%. These mortgages are secured by 12 specific manufactured home

D-32

communities and are subject to early pre-payment penalties, the terms of which vary from mortgage to mortgage.

c): Notes assumed in conjunction with the D.A.M. portfolio purchase. These notes total approximately $27.0 million, mature in 2008 and carry an average effective annual interest rate of 7.18%. These mortgages are secured by 23 specific manufactured home communities.

Floorplan Lines of Credit

On November 11, 2005, we amended our floorplan line of credit to provide borrowings of up to $35.0 million, secured by manufactured homes in inventory. Under the amended lines of credit, the lender will advance 75% of the cost of manufactured homes. Repayments of borrowed amounts are due upon sale or lease of the related manufactured home. Advances under the amended lines of credit will bear interest ranging from the prime rate plus 0.75% to the prime rate plus 4.00% (averaging 9.00% at March 31, 2007) based on the length of time each advance has been outstanding. Monthly curtailment payments are required for unsold homes beginning 360 days following the purchase of the home. The required curtailment payment will be between 3.00% and 5.00% of the home's original invoice amount depending on the type of home and the number of months since the home's purchase. The amended lines of credit require us to maintain a minimum tangible net worth, a maximum debt to tangible net worth ratio of 3 to 1, and minimum cash and cash equivalents of $15.0 million, all as defined in the agreement. As amended, the minimum tangible net worth required is $385.0 million from January 1, 2007 through September 13, 2007, the due date of the line. We are in compliance with all financial covenants of the line of credit as of March 31, 2007. The line of credit is subject to a commitment fee of $250,000, an unused line fee of .25% per annum and a termination fee of 1.00% to 3.00%, based on the termination date.

Trust Preferred Securities Due 2035

On March 15, 2005, the Partnership issued $25.8 million in unsecured trust preferred securities to ARC. The $25.8 million trust preferred securities bear interest at three-month LIBOR plus 3.25% (8.60% at March 31, 2007). Interest on the securities is paid on the 30^th of March, June, September and December of each year. The Partnership may redeem these securities on or after March 30, 2010 in whole or in part at principal amount plus accrued interest. The securities are mandatorily redeemable on March 15, 2035 if not redeemed sooner.

Consumer Finance Facility

We entered into the Retail Home Sales and Consumer Finance Debt Facility (the "Consumer Finance Facility") on February 18, 2004, in connection with the completion of our IPO and the Hometown acquisition and amended it in April 2005 in connection with entering into a two-year, $75.0 million secured revolving lease receivables credit facility (see Lease Receivables Facility below). The Consumer Finance Facility has a total commitment of $125.0 million and a term of four years. This facility is an obligation of one of our subsidiaries, and borrowings under this facility are secured by manufactured housing conditional sales contracts. Borrowings under the facility are limited by specified borrowing base requirements related to the value of the collateral securing the facility ($14.9 million at March 31, 2007). The facility bears interest at a variable rate based upon a spread of 3.00% over the one-month LIBOR (8.32% at March 31, 2007). During the first quarter of 2007, we paid a commitment fee of 0.25% of the amended committed amount. Advances under the facility are subject to a number

D-33

of conditions, including certain underwriting and credit screening guidelines and the conditions that the home must be located in one of our communities, the loan term may not exceed 12 years for a single-section home or 15 years for a multi-section home and the loan amount shall not exceed 90% of the value of the home securing the conditional sales contract.

The Consumer Finance Facility was amended for financial covenants in October 2005. The amended line of credit requires the OP to maintain a minimum tangible net worth, a maximum debt to tangible net worth ratio of 3 to 1, and minimum cash and cash equivalents of $15.0 million, all as defined in the agreement. As amended, the minimum tangible net worth required is $385.0 million from January 1, 2007 through December 31, 2007, and $355.0 million from January 1, 2008 through February 18, 2008. We were in compliance as of March 31, 2007 with all financial covenants under the amended line of credit.

The availability of advances under the Consumer Finance Facility is subject to certain conditions that are beyond our control. Conditions that could result in our inability to draw on these facilities include a downgrade in the credit rating of the lender and the absence of certain markets for financing debt obligations secured by securities or mortgage loans. Funding under this facility may also be denied if the lender determines that the value of the assets serving as collateral would be insufficient to maintain the required 75% loan-to-value ratio upon giving effect to a request for funding. The lender can also at any time require that we prepay amounts funded or provide additional collateral if, in its judgment, this is necessary to maintain the 75% loan-to-value ratio.

Lease Receivables Facility

On April 6, 2005, the Company entered into a two-year, $75.0 million secured revolving credit facility (the "Lease Receivables Facility") with Merrill Lynch Mortgage Capital Inc. to be used to finance the purchase of manufactured homes and for general corporate purposes. In October 2005, we amended our lease receivables facility to increase the size of the facility from $75 million to $150 million. The amendment also (i) increased the limit on borrowings under the lease receivables facility from an amount equal to approximately 55% of the net book value of the eligible manufactured housing units owned by two of our indirect wholly owned subsidiaries, ARC Housing LLC and ARC HousingTX LP (collectively, "Housing") and located in ARC's communities, to 65%, subject to certain other applicable borrowing base requirements, (ii) increased the interest rate on borrowings under the facility from 3.25% plus one-month LIBOR to 4.125% plus one-month LIBOR (9.445% at March 31, 2007), and (iii) extended the maturity of the facility from March 31, 2007 to September 30, 2008.

The amended line of credit requires the OP to maintain a minimum tangible net worth, a maximum debt to tangible net worth ratio of 3 to 1, and minimum cash and cash equivalents of $15.0 million, all as defined in the agreement. As amended, the minimum tangible net worth required is $385.0 million from January 1, 2007 through December 31, 2007, and $355.0 million from January 1, 2008 through September 30, 2008. We were in compliance as of March 31, 2007 with all financial covenants under the amended line of credit. Borrowings under the Lease Receivables Facility are secured by an assignment of all lease receivables and rents, an assignment of the underlying manufactured homes and a pledge by ARCHC LLC and ARC Housing GP LLC of 100% of the outstanding equity in Housing. Interest is payable monthly.

D-34

Senior Exchangeable Notes Due 2025

In August 2005, our OP issued $96.6 million aggregate principal amount of 7.50% senior exchangeable notes due 2025 to qualified institutional buyers in a private transaction. The notes are senior unsecured obligations of the OP and are exchangeable, at the option of the holders, into shares of ARC common stock at an initial exchange rate of 69.8812 shares per $1,000 principal amount of the notes (equal to an initial exchange price of approximately $14.31 per share), subject to adjustment and, in the event of specified corporate transactions involving ARC or the OP, an additional make-whole premium. Upon exchange, the OP shall have the option to deliver, in lieu of shares of ARC common stock, cash or a combination of cash and shares of ARC common stock.

According to the terms of the notes, their initial exchange rate is adjusted for certain events, including the issuance to all holders of ARC common stock of rights entitling them to purchase ARC common stock at less than their current market price. Accordingly, as a result of our rights offering in January 2007, in which we offered all holders of ARC common stock the right to purchase shares at $8.00 per share, the initial exchange rate of the notes was adjusted to 73.95 shares per $1,000 principal amount of the notes (equal to an initial exchange rate of $13.52 per share).

Prior to August 20, 2010, the notes are not redeemable at the option of the OP. After August 20, 2010, the OP may redeem all or a portion of the notes at a redemption price equal to the principal amount plus accrued and unpaid interest, if any, on the notes, if the closing price of ARC common stock has exceeded 130% of the exchange price for at least 20 trading days in any consecutive 30-trading day period.

Holders of the notes may require the OP to repurchase all or a portion of the notes at a purchase price equal to the principal amount plus accrued and unpaid interest, if any, on the notes on each of August 15, 2010, August 15, 2015, and August 15, 2020, or after the occurrence of certain corporate transactions involving ARC or the OP.

7. Discontinued Operations

As of December 31, 2005, the Company held 41 communities as discontinued operations and as of March 31, 2006 had closed sales for 27 of these communities comprising $34.2 million of cash proceeds net of related debt, defeasance and other closing costs of $34.3 million. Subsequent to March 31, 2006, we closed an additional 13 communities for $51.2 million of cash proceeds net of related debt, defeasance and other closing costs of $40.7 million. The remaining sales transaction is expected to close in 2008. There can be no assurance, however, that the Company will close the remaining community sale, or, if it closes, that it will close on the terms set forth in its contract.

In accordance with the provisions of Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-lived Assets," each of the communities designated as held for sale and not sold have been classified as discontinued operations as of March 31, 2007 and December 31, 2006. We have included $15.5 million and $15.3 million of net assets related to these communities as assets held for sale in the accompanying consolidated balance sheets as of March 31, 2007 and December 31, 2006, respectively, and $0.1 million and $0.2 million, respectively, of accounts payable and other obligations related to these communities as liabilities related to assets held for sale. In addition, we have recast the operations of each of these communities as discontinued operations in the accompanying statements of operations for the three months ended March 31, 2007 and 2006 and recorded a gain of $10.3 million related to the sale of the discontinued operations for the quarter ended March 31, 2006 in connection with these sales.

In the normal course of business, from time to time we are involved in legal actions relating to the ownership and operations of our properties. In our opinion, the liabilities, if any, which may ultimately result from such legal actions, will not have a material adverse effect on our financial position, results of operations or cash flows. In the normal course of business, from time to time we incur environmental obligations relating to the ownership and operation of our properties. In our opinion, the liabilities, if any, which may ultimately result from such environmental obligations, will not have a material adverse effect on our financial position, results of operations or cash flows.

12. Subsequent Events

In April 2007, ARC entered into a definitive transaction agreement with the Buyer providing for the sale of ARC MH and the repayment of certain notes payable. The gross proceeds to ARC will be $1.794 billion consisting of cash and assumed debt, subject to adjustment. It is anticipated that ARC will utilize a significant portion of its existing net operating losses ("NOL"s) in the transaction. ARC will retain approximately $125.0 million par value of Series A Preferred Stock and $96.6 million of Senior Exchangeable Notes Due 2025. ARC will retain its ownership of the recently acquired NLASCO insurance operations, and it will seek to make opportunistic acquisitions with the proceeds from the transaction. The transaction is expected to be completed by the end of 2007, subject to receipt of stockholder approval as well as the satisfaction of other customary closing conditions. Farallon has agreed to offer positions to all of ARC's employees currently engaged in the manufactured home community business on substantially the same terms as at present.

The agreement may be terminated under certain circumstances, including if the ARC's Board of Directors has determined in good faith that it has received a superior proposal, ARC enters into a definitive agreement with respect to such superior proposal and the Company otherwise complies with certain terms of the agreement. Upon the termination of the agreement under certain specified circumstances, ARC will be required to pay the Buyer a termination fee of $20 million and to reimburse the Buyer for its transaction expenses up to $5 million; upon the termination of the agreement under other specified circumstances, the Buyer will be required to pay ARC a termination fee of either $37.5 million or $50 million. Farallon Capital Partners, L.P. has agreed to guarantee, subject to the terms, conditions and limitations of such guarantee, certain payment obligations of the Buyer under the agreement.

Independent Auditors' Report

The Stockholders
NLASCO, Inc. and Subsidiaries:

We have audited the accompanying consolidated balance sheets of NLASCO, Inc. and Subsidiaries (the Company) as of December 31, 2006 and 2005, and the related consolidated statements of income, comprehensive income, changes in stockholders' equity and cash flows for the years ended December 31, 2006 and 2005. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of NLASCO, Inc. and Subsidiaries as of December 31, 2006 and 2005, and the results of their operations and their cash flows for the years ended December 31, 2006 and 2005, in conformity with accounting principles generally accepted in the United States of America.

Our audit was made for the purpose of forming an opinion on the basic consolidated financial statements taken as a whole. The supplementary information included on Schedules I through III is presented for purpose of additional analysis and is not a required part of the basic consolidated financial statements. Such information has been subjected to the auditing procedures applied in the audit of the basic consolidated financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic consolidated financial statements taken as a whole.

The accompanying statements of income, comprehensive income, changes in stockholders' equity and cash flows for the year ended December 31, 2004, were not audited by us and, accordingly, we do not express an opinion on them.

NLASCO, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2006, 2005 and 2004

(1) Summary of Significant Accounting Policies

(a) Description of Business

NLASCO, Inc. and Subsidiaries, collectively referred to as the Company, writes property and casualty insurance policies (principally homeowners, fire and allied lines) primarily in the states of Texas and Arizona through independent insurance agents.

The Company has exposure to catastrophes, an inherent risk of the property and casualty insurance business, which have contributed to, and will continue to contribute to, material fluctuations in the Company's results of operations and financial position. The level of catastrophic loss and weather-related losses experienced in any year cannot be predicted and could be material to results of operations and financial position.

(b) Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which differ from statutory accounting practices prescribed or permitted for insurance companies by regulatory authorities.

The consolidated financial statements include the accounts of NLASCO, Inc. and its wholly-owned subsidiaries: National Group Corporation and its wholly-owned subsidiaries (Excalibur Financial Corporation, National Lloyds Insurance Company, and NAGRUPCO, Ltd.); American Summit Insurance Company; J. E. Murphy Co., Inc.; J. E. Murphy Co., Inc. of Florida; NALICO General Agency and NLASCO Services, Inc. All significant intercompany balances and transactions have been eliminated in consolidation.

(d) Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions are important in determining the liability for losses and loss adjustment expenses; the balance of deferred policy acquisition costs; carrying amount of goodwill; and valuation allowances for receivables and deferred income tax assets. Actual results could differ from those estimates.

(e) Investment Securities

Investment securities at December 31, 2006 and 2005 consist of U. S. Government, mortgage-backed, corporate debt, and equity securities. The Company classifies its fixed maturities in one of three categories: trading, available-for-sale, or held-to-maturity; and its equity securities are classified as trading or available-for-sale. Trading securities are bought and held principally for the purpose of selling them in the near term. Held-to-maturity debt securities are those securities in which the Company has the ability and intent to hold the security until maturity. All securities not included in trading or held-to-maturity are classified as available-for-sale.

E-8

(e) Investment Securities (Continued)

Trading and available-for-sale securities are recorded at fair value. Held-to-maturity debt securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Unrealized holding gains and losses on trading securities are included in earnings. Unrealized holding gains and losses, net of the related tax effect, on available-for-sale securities are excluded from earnings and are reported as a separate component of other comprehensive income until realized. Realized gains and losses from the sale of trading and available-for-sale securities are determined on a specific-identification basis.

The Company regularly reviews its investment securities to assess whether the amortized cost is impaired and if impairment is other than temporary. A decline in the market value of any available-for-sale or held-to-maturity security below cost that is deemed to be other-than-temporary results in a reduction in carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. To determine whether an impairment is other-than-temporary, the Company considers whether it has the ability and intent to hold the investment until a market price recovery and considers whether evidence indicating the cost of the investment is recoverable outweighs evidence to the contrary. Evidence considered in this assessment includes the reasons for the impairment, the severity and duration of the impairment, changes in value subsequent to year-end, and forecasted performance of the investee.

Premiums and discounts are amortized or accreted over the life of the related held-to-maturity or available-for-sale security as an adjustment to yield using the effective-interest method. Dividend and interest income are recognized when earned.

(f) Cash and Cash Equivalents

Cash and cash equivalents consist primarily of money market mutual funds. Cash and cash equivalents are highly liquid investments with original maturities of three months or less.

(g) Premium and Agents' Balances

Premium and agents' balances include premiums written and not yet collected. The Company regularly evaluates premiums receivable and establishes valuation allowances as appropriate. At December 31, 2005 and 2004 the Company determined no valuation allowance was necessary.

(h) Mortgage Loans on Real Estate

Mortgage loans on real estate are reported at unpaid principal balances, less an allowance for credit losses, if needed.

The allowance for credit losses is the Company's best estimate of the amount of probable credit losses in the Company's existing notes. The allowance is determined on an individual note basis upon review of any note that has a payment past due for over sixty days. A note is considered impaired pursuant to FASB Statement No. 114, Accounting by Creditors for Impairment of a Loan. A note is impaired if it is probable that the Company will not collect all principal and interest contractually due. The impairment is measured based on the present value of expected future cash flows discounted at

E-9

(h) Mortgage Loans on Real Estate (Continued)

the note's effective interest rate. The Company does not accrue interest when a note is considered impaired. When ultimate collectibility of the principal balance of the impaired note is in doubt, all cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and are recognized as interest income thereafter. Impairment losses are charged against the allowance and increases in the allowance are charged to bad debt expense. Notes are written off against the allowance when all possible means of collection have been exhausted and the potential for recovery is considered remote.

(i) Deferred Policy Acquisition Costs

Commissions and other costs of acquiring insurance that vary with and are primarily related to the production of new and renewal business are deferred and amortized over the terms of the policies or reinsurance treaties to which they relate. Proceeds from reinsurance transactions that represent recovery of acquisition costs shall reduce applicable unamortized acquisition costs in such a manner that net acquisition costs are capitalized and charged to expense in proportion to net revenue recognized. Future investment income is considered in determining the recoverability of deferred acquisition costs. The Company regularly reviews the categories of acquisition costs that are deferred and assesses the recoverability of this asset. A premium deficiency and a corresponding charge to income is recognized if the sum of the expected loss and loss adjustment expenses, unamortized acquisition costs, and maintenance costs exceed related unearned premiums and anticipated investment income. At December 31, 2006 and 2005, there was no premium deficiency.

(j) Equipment and Building Held for Sale

Equipment and building held for sale are stated at cost. Depreciation is calculated on the straight-line method over the estimated useful lives of the assets.

(k) Treasury Stock

Treasury stock purchases are recorded under the cost method, whereby the entire cost of the acquired stock is recorded as treasury stock.

(l) Goodwill

Goodwill represents the excess of the cost over fair value of assets of businesses acquired. Goodwill is tested annually for impairment and is tested more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset's fair value. For goodwill, the impairment determination is made at the reporting unit level and consists of two steps. First, the Company determines the fair value of a reporting unit and compares it to its carrying amount. Second, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit's goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a

E-10

purchase price allocation, in accordance with FASB Statement No. 141, Business Combinations. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill.

(m) Losses and Loss Adjustment Expenses

The liability for losses and loss adjustment expenses includes an amount determined from loss reports and individual cases and an amount, based on past experience, for losses incurred but not reported. Such liabilities are necessarily based on estimates and, while management believes that the amount is adequate, the ultimate liability may be in excess of or less than the amounts provided. The methods for making such estimates and for establishing the resulting liability are continually reviewed, and any adjustments are reflected in earnings currently. The liability for losses and loss adjustment expenses have not been reduced for reinsurance recoverable.

(n) Premium Revenue Recognition

Property and liability premiums are generally recognized as revenue on a pro rata basis over the policy term. The portion of premiums that will be earned in the future are deferred and reported as unearned premiums.

(o) Reinsurance

In the normal course of business, the Company seeks to reduce the loss that may arise from catastrophes or other events that cause unfavorable underwriting results by reinsuring certain levels of risk in various areas of exposure with other insurance enterprises or reinsurers. Amounts recoverable from reinsurers are estimated in a manner consistent with the reinsured policy.

(p) Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

(q) Advertising Costs

Advertising costs are expensed as incurred. Advertising costs charged to operations totaled approximately $0.2 million for each of the years ended December 31, 2005, 2004 and $0.3 million in 2003.

U.S. Government securities: The unrealized losses on the Company's investments in U.S. Government securities were caused by interest rate increases. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost of the investment. Because the Company has the ability and could hold these investments until a recovery of fair value, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2006.

Mortgage-backed securities: The unrealized losses on the Company's investments in mortgage-backed securities were caused by interest rate increases. The contractual cash flows of the investments are guaranteed by an agency of the U.S. government. Accordingly, it is expected that the securities

E-14

would not be settled at a price less than the amortized cost of the Company's investment. Because the decline in market value is attributable to changes in interest rates and not credit quality and because the Company has the ability and intent to hold these investments until a recovery of fair value, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at December 31, 2006.

Corporate debt securities: The unrealized loss on the Company's investments in corporate debt was primarily caused by interest rate increases. Because the Company has the ability and intent to hold these investments until a recovery of fair value, which may be maturity, it does not consider these investments to be other-than-temporarily impaired at December 31, 2006.

Equity securities: The unrealized loss on the Company's investments in equity securities was caused primarily by changes in the speculative value of the per share price of securities traded on public stock exchanges. Because the Company has the ability and intent to hold these investments until recovery of fair value, it does not consider these investments to be other-than-temporarily impaired at December 31, 2006.

Mortgage loans on real estate consist of one residential and one commercial mortgage with interest rates between 6.0% and 6.5%. As of December 31, 2006, none of the mortgages have payments past due and no allowance for credit losses was provided.

Net investment income for the years ended December 31, 2006, 2005 and 2004 was as follows:

Depreciation expense charged to operations for the years ended December 31, 2006 and 2005, totaled $0.3 million and $0.5 million, respectively.

(4) Land and Building Held for Sale

During 2005, the Company moved its insurance operations located in Scottsdale, Arizona to its home office in Waco, Texas and placed the associated office building in Arizona for sale. In February 2006, the Company sold the office building in Arizona to an unrelated party. Proceeds on the sale amounted to $2.0 million, and the gain on disposition of $0.9 million was recognized. Depreciation expense charged to operations during the year ended December 31, 2006 amounted to $42,000.

(5) Policy Acquisition Expenses

Policy acquisition expenses, primarily commissions, premium taxes and underwriting expenses related to issuing a policy are deferred and charged against income ratably over the terms of the related policies.

Ending deferred policy acquisition costs	$	16,574		$	13,094		$	8,236

(6) Reinsurance Activity

The Company limits the maximum net loss that can arise from large risks or risks in concentrated areas of exposure by reinsuring (ceding) certain levels of risk. Substantial amounts of business are ceded, and these reinsurance contracts do not relieve the Company from its obligations to policyholders. Such reinsurance includes quota share, excess of loss, catastrophe, and other forms of reinsurance on essentially all property and casualty lines of insurance. Failure of reinsurers to honor their obligations could result in losses to the Company; consequently, allowances are established for amounts deemed uncollectible. The Company evaluates the financial condition of its reinsurers and

E-16

monitors concentrations of credit risk arising from similar geographic regions, activities, or economic characteristics of the reinsurers to minimize its exposure to significant losses from reinsurer insolvencies.

The effect of reinsurance on premiums written and earned for the years ended December 31, 2006, 2005 and 2004 is as follows (dollars in thousands):

	2006						2005						2004
	Written			Earned			Written			Earned			Written			Earned
													(Unaudited)
Premiums from direct business	$	141,597		$	144,280		$	146,542		$	146,258		$	145,724		$	139,834

Recoveries pertaining to reinsurance contracts that are deducted from losses and loss adjustment expenses incurred during 2006, 2005 and 2004 are approximately $12.4 million, $118.0 million and $20.4 million, respectively.

(7) Notes Payable

Notes payable at December 31, 2006 and 2005 consisted of the following (in thousands):

	2006		2005
$3.85 million note payable to an unrelated party which bears interest at 3.5%; principal is due at maturity in January 2007; unsecured	$	3,850	$	—

E-17

$10 million surplus note payable to an unaffiliated company, issued by National Lloyds Insurance Company, which bears interest equal to the three-month LIBOR plus 4.05% (9.39% at December 31, 2006); interest is due quarterly and principal is due at maturity in September 2033; unsecured		10,000		10,000

	$	55,202	$	50,782

The loan agreements relating to the notes payable contain various covenants pertaining to limitations on additional debt, dividends, and officer and director compensation, and minimum capital requirements. For 2006, the Company violated the covenants relating to limitations on officer and director compensation; however, the financial institution waived that requirement of the agreement for 2006.

The surplus notes payable issued by National Lloyds Insurance Company are subordinate in right of payment to all policy claims and other indebtedness of the Company. Further, all payments of principal and interest require the prior approval of the Insurance Commissioner of the State of Texas and are only payable to the extent that the surplus of National Lloyds Insurance Company exceeds $30 million.

The surplus note payable issued by American Summit Insurance Company is subordinate in right of payment to all policy claims and other indebtedness of the Company. Further, all payments of principal and interest require the prior approval of the Insurance Commissioner of the State of Texas and are only payable to the extent that the surplus of American Summit Insurance Company exceeds $15 million.

Interest expense from notes payable charged to operations totaled $2.6 million and $4.0 million for 2006 and 2005, respectively, and is included in other underwriting expenses.

E-18

The aggregate maturities of notes payable for each of the five years subsequent to December 31, 2006 are as follows (in thousands):

Year	Principal Amount Due
2007	$	7,439

	2006		2005
$8 million note payable to an affiliated company which bears interest at the LIBOR rate plus 2% (7.34% at December 31, 2006); subordinated to all other notes payable; principal is due at maturity in February 2012; unsecured		5,600		5,600

	$	5,600	$	5,600

Interest expense from indebtedness to related parties charged to operations totaled $0.4 million and $0.8 million for 2006 and 2005, respectively, and is included in other underwriting expenses.

E-19

(9) Liability for Unpaid Losses and Loss Adjustment Expenses

An analysis of the liability for unpaid losses and loss adjustment expenses for December 31, 2006, 2005 and 2004 is as follows (dollars in thousands):

			2006			2005			2004
									(Unaudited)
Balance at January 1			$	41,379		$	24,648		$	17,839
	Less reinsurance recoverables			(17,433	)		(5,962	)		(5,561	)

		Net balance at January 1		23,946			18,686			12,278

Incurred related to:
	Current year			63,763			55,407			47,503
	Prior years			(8,961	)		(6,838	)		(4,505	)

		Total incurred		54,802			48,569			42,998

Paid related to:
	Current year			53,152			38,822			33,395
	Prior years			7,086			4,487			3,195

		Total paid		60,238			43,309			36,590

Net balance at December 31				18,510			23,946			18,686
	Plus reinsurance recoverables			2,002			17,433			5,962

		Balance at December 31	$	20,512		$	41,379		$	24,648

The liability for losses and loss adjustment expenses for prior years decreased as a result of changes in estimates of insured events from ongoing analysis of recent loss development trends and additional information regarding individual claims.

(10) Derivative Instrument

The Company has an interest-rate-related derivative instrument with an affiliated company who is the creditor of the $5.6 million note payable to affiliate described in Note 8. The note payable to the affiliated company has a variable interest rate which exposes the Company to variability in interest payments due to changes in the interest rate. To limit the variability of a portion of its interest payments, the Company entered into an interest rate swap agreement to exchange its variable interest rate, pertaining to one-half of the principal amount of the note payable ($2.0 million as of December 31, 2006), for a fixed rate of 6.98%.

The fair value of interest rate swaps designed as hedging instruments that effectively offset the variability of cash flows associated with variable interest rate, long-term debt obligations should be reported at fair value, with the changes in fair value reported in accumulated other comprehensive income or loss. The amounts should subsequently be reclassified into interest expense as yield adjustment of the hedged interest payments in the same period in which the related interest affects earnings. However, due to current market conditions and the proximity of the note's current variable interest rate to the agreement's fixed rate, the effects of the derivative instrument were determined to be immaterial to the consolidated financial statements taken as a whole and have not been reported in the accompanying consolidated financial statements.

E-20

(11) Income Taxes

The Company's effective tax rate is different than what would be expected if the federal statutory rate of 35% were applied to income before income taxes primarily because of non-deductible expenses and changes in the estimate for the prior year provision.

The tax effects of temporary differences that give rise to significant portions of deferred tax assets and deferred tax liabilities at December 31, 2006 and 2005 consisted of the following (in thousands):

		2006			2005
Deferred tax assets:
Unearned premiums, due to difference in allowable amount for tax purposes		$	4,677		$	4,119
Losses and loss adjustment expenses, due to discounting for tax purposes			565			717
Accrued interest to affiliated companies, due to deduction limited for tax purposes			23			523
Securities available for sale, due to recognition of unrealized losses for book purposes			539			227
Other			24			160

	Total deferred tax assets		5,828			5,746

Deferred tax liabilities:
Deferred policy acquisition costs, due to recording for book purposes			(5,801	)		(4,583	)
Goodwill, due to amortization allowed for tax purposes			(2,431	)		(728	)
Loan origination costs, due to recording for book purposes			(182	)		(189	)
Other			(60	)		(59	)

	Total deferred tax liabilities		(8,474	)		(5,559	)

Net deferred tax assets (liabilities)		$	(2,646	)	$	187

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences at December 31, 2006. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if the estimates of future taxable income during the carryforward period are reduced.

E-21

(12) Statutory Net Income and Stockholders' Equity

The Company's insurance subsidiaries, which are domiciled in the State of Texas, prepare their statutory financial statements in accordance with accounting principles and practices prescribed or permitted by the Texas Department of Insurance, which Texas recognizes for determining solvency under Texas State Insurance Law. The Commissioner of the Texas Department of Insurance has the right to permit other practices that may deviate from prescribed practices. Prescribed statutory accounting practices are those practices that are incorporated directly or by reference in state laws, regulations, and general administrative rules applicable to all insurance enterprises domiciled in Texas. Permitted statutory accounting practices encompass all accounting practices that are not prescribed; such practices differ from state to state, may differ from company to company within a state, and may change in the future.

The Company's insurance subsidiaries' statutory financial statements are presented on the basis of accounting practices prescribed or permitted by the Texas Department of Insurance. Texas had adopted the National Association of Insurance Commissioners' statutory accounting practices as the basis of its statutory accounting practices with certain differences which are not significant to the companies' statutory equity.

In addition, the Commissioner of the Texas Department of Insurance has the right to permit other specific practices that may deviate from prescribed practices. The Company's insurance subsidiaries have no such permitted statutory accounting practices.

Following is a summary of statutory capital and surplus and statutory net income of each insurance subsidiary as of December 31 (in thousands):

		2006		2005		2004
						(unaudited)
National Lloyds Insurance Company:
	Surplus	$	82,836	$	81,136	$	71,715

	Net income	$	17,640	$	13,093	$	13,154

American Summit Insurance Company:
	Capital and Surplus	$	21,517	$	23,075	$	22,263

	Net income	$	3,611	$	1,438	$	2,129

(13) Capital and Dividend Restrictions

The funding of the cash requirements (including debt service) of NLASCO, Inc. is primarily provided by cash dividends from the Company's wholly-owned insurance subsidiaries. Dividends paid by the insurance subsidiaries are restricted by regulatory requirements of the Texas Department of Insurance. Under Texas State Insurance Law for property and casualty companies, all dividends must be distributed out of earned surplus only. Furthermore, without the prior approval of the Commissioner, dividends cannot be declared or distributed which exceed the greater of ten percent of the Company's surplus, as shown by its last statement on file with the Commissioner, or one hundred percent of net income for such period. The subsidiaries paid cash dividends to the Company of

E-22

$15.2 million during the year ended December 31, 2006. At December 31, 2006, the maximum dividend that may be paid to the Company in 2007 without regulatory approval is approximately $21.2 million.

Regulations of the Texas Department of Insurance require insurance companies to maintain minimum levels of statutory surplus to ensure their ability to meet their obligations to policyholders. At December 31, 2006, the Company's insurance subsidiaries had statutory surplus in excess of the minimum required.

Also, the National Association of Insurance Commissioners (NAIC) has adopted a risk based capital (RBC) formula for insurance companies that establishes minimum capital requirements relating to insurance risk, asset credit risk, interest rate risk and business risk. The formula is used by the NAIC and certain state insurance regulators as an early warning tool to identify companies that require additional scrutiny or regulatory action. At December 31, 2006, the Company's insurance subsidiaries' RBC ratio exceeded the level at which regulatory action would be required.

(14) Commitments and Contingencies

The Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company's financial position.

The Company is subject to guaranty fund assessments by the states in which it writes business. Guaranty fund assessments are accrued when the amount of loss on the related insolvencies is probable and reasonably estimated. Loss estimates are based on information from the various property and casualty insurance associations and may change due to many factors. Windstorm and other assessments for catastrophic losses related to Hurricane Katrina were $6.1 million during 2006 which were fully covered through reinsurance.

The Company's insurance subsidiaries periodically submit premium rates the insurance companies intend to charge their policyholders for various lines of business to state insurance departments to whose jurisdiction the companies are subject. These initial rate filings are subject to adjustment by the states, which could result in significant reductions in the amount of premium income for the Company. In the opinion of management, any future rate adjustments will not have a material adverse impact on the Company's financial condition.

The Company leases office space from two affiliated entities under operating leases which expire in December 2009, and an additional month-to-month operating lease agreement. Total lease payments made by the Company were approximately $585 thousand, $670 thousand and $701 thousand for 2006, 2005 and 2004, respectively. Future minimum lease payments under these lease agreements are as follows (in thousands):

2007	$	7,439
2008	$	9
2009	$	10
2010	$	11
2011	$	12

E-23

(15) Employee Benefit Plan

The Company has a contributory defined contribution 401(k) retirement plan. The Company matches a stated percentage of employee contributions up to a defined maximum. An employee is eligible to participate in the plan after one year of employment and is fully vested after five years of employment. Contributions to the plan by the Company totaled $92 thousand, $116 thousand and $98 thousand for the years ended December 31, 2006, 2005 and 2004, respectively.

(16) Disclosures About Fair Value of Financial Instruments

In the normal course of business, the Company invests in various financial assets and incurs various financial liabilities. The fair value estimates of financial instruments presented below are not necessarily indicative of the amounts the Company might pay or receive in actual market transactions. Potential taxes and other transaction costs have not been considered in estimating fair value. The disclosures that follow do not reflect the fair value of the Company as a whole since a number of the Company's significant assets (including deferred policy acquisition costs, land and buildings, deferred income taxes) and liabilities are not considered financial instruments and are not carried at fair value. Other assets and liabilities considered financial instruments such as cash and cash equivalents, premium and agents' balances, reinsurance receivable, prepaid reinsurance premiums, loss and loss adjustment expenses outstanding, unearned premiums, and reinsurance balances payable are generally of a short-term nature. Their carrying values are deemed to approximate fair value.

Financial assets (dollars in thousands)

	December 31, 2006				December 31, 2005
	Carrying Value		Fair Value		Carrying Value		Fair Value
Fixed maturities	$	115,062	$	115,061	$	114,487	$	114,536
Equity securities		10,583		10,583		12,563		12,563
Mortgage loans		5,391		5,391		6,573		6,573

Fair values of investment securities are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. The fair value of mortgage loans is estimated as the unpaid principal balance of the loans, which approximates the discounted future cash flows using current rates at which similar loans would be made with similar credit ratings and the same remaining maturities.

Financial liabilities (dollars in thousands)

		December 31, 2006						December 31, 2005
		Carrying Value			Fair Value			Carrying Value			Fair Value
Notes payable		$	60,802		$	60,802		$	56,382		$	56,382

The notes payable are periodically adjusted to market interest rates; therefore, the unpaid principal balance of the loan approximates fair value.

E-24

(17) Business and Credit Concentrations

Significant concentrations of business in any one marketing or geographic area could negatively impact the Company's operations in the event of concentration of losses, regional economic downturns, or adverse regulatory action. The Company is licensed to write insurance in several states; however, approximately 82% of the Company's direct written premiums in 2006 were written in the states of Texas and Arizona.

Inadequate investment diversification can subject a company to a degree of risk arising from such factors as interest rate fluctuations, credit deterioration, market fluctuations and changes in regulatory and political policy which can result in actual losses or inadequate investment returns. The Company, as of December 31, 2006 and periodically during the year, maintained balances in various deposit accounts and certificates of deposit at financial institutions in excess of federally insured limits. Management believes the possibility of a significant adverse impact upon the financial condition of the Company arising from such risks to be remote.

At December 31, 2006, one commercial loan on real estate to an affiliate amounted to $5.3 million as disclosed in Note 8.

(18) Supplemental Cash Flow Information

The Company paid $6.3 million, $3.9 million and $2.8 million for interest and $5.8 million, $6.0 million and $9.7 million for income taxes during the years ended December 31, 2006, 2005 and 2004, respectively.
