AUDIT COMMITTEE

each financially literate as required by the Nasdaq National Market listing

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 requires that our executive
officers, directors and persons who own more than ten percent of a registered
class of our equity securities file reports of ownership and changes in
ownership with the SEC. Executive officers, directors and greater-than-ten
percent stockholders are required by SEC regulations to furnish us with all
Section 16(a) forms that they file. Based solely upon our review of copies of
the forms received by us and written representations from certain reporting
persons that they have complied or not complied with the relevant filings
requirements, we believe that, during the year ended December 31, 2004, all of
our executive officers, directors and greater-than-ten percent stockholders
complied with all Section 16(a) filing requirements except for one Form 4 filed
by Dawn R. Olsen, which reported one transaction.

employees, including our Chief Executive Officer, Chief Financial Officer,
Principal Accounting Officer and all other senior financial executives, and to
our directors when acting in their capacity as directors. Our Code of Ethics and

and to help directors and employees resolve ethical issues. The purpose of our
Code of Ethics and Business Conduct is to ensure to the greatest possible extent
that our business is conducted in a consistently legal and ethical manner.
Employees may submit concerns or complaints regarding audit, accounting,

                                       4



confidential basis by means of a toll-free telephone call or an anonymous email.
We investigate all concerns and complaints. Copies of our Code of Ethics and
Business Conduct are posted on our website at

provision of our Code of Ethics and Business Conduct that apply to our Chief
Executive Officer, Chief Financial Officer, Principal Accounting Officer and
persons performing similar functions and amendments to, or waivers from, any
provision which relates to any element of our Code of Ethics and Business
Conduct described in Item 406(b) of Regulation S-K.

(1)  In accordance with SEC rules, disclosure is omitted where total Other
     Annual Compensation does not exceed $50,000. The Company provides each of
     Robert L. Antin, Arthur J. Antin and Tomas W. Fuller the use of a Company
     owned automobile and reimburses them for the cost of their automobile
     insurance in connection with their use of the automobile. The table below
     sets forth the total cost (including both business related and personal) to
     the Company of providing these benefits:

        NAME                2004     2003     2002
     ------------         -------  -------  --------

     Tomas W. Fuller       18,780   20,025   21,025

     For disclosure puporses, the annual cost of the Company owned automobile
     was determined based on the Annual Lease Value as provided in the Internal
     Revenue Code.

     Pursuant to the terms of his employment agreement, Mr. Robert L. Antin is
     reimbursed for entertainment related business expenses which principally
     include tickets to cultural and sporting events, and totaled $91,517,
     $76,655 and $79,356 in 2004, 2003 and 2002, respectively. The costs of
     these activities are incurred in connection with his entertainment of
     customers, vendors, employees and strategic partners and are
     business-related and are not maintained as perquisites or otherwise for the
     personal benefit of Mr. Robert L. Antin. As a result, the Company has not
     included these costs in the Other Annual Compensation column.

     

                                       6




     Taking into account the portion of the automobile costs allocated to personal
     use and the other perquisites provided to the executive officers, the
     perquisites did not exceed $50,000 in any of 2004, 2003 and 2002 and
     consequently are not included in the Other Annual Compensation column.

(2)  All numbers reflect the number of shares of our common stock subject to
     options granted during the fiscal year indicated. The numbers of shares of
     our common stock subject to options granted during fiscal years 2002 and
     2003 have been adjusted to reflect a 100% stock dividend paid by us in
     August. 

(3)  All Other Compensation consists of Company contributions to the 401(k)
     Plan.

DIRECTORS' COMPENSATION

We pay our non-employee directors $10,000 per year and $1,000 for each Board of
Directors meeting attended in person or committee meeting attended in person
which is not held on the same day as a Board of Directors meeting, including
reimbursement for out-of-pocket expenses incurred in attending. We pay the
Chairman of our Audit Committee an additional $10,000 per year. Upon appointment
to the Board of Directors, each non-employee director receives an initial grant
of options to purchase 30,000 shares of common stock at the fair market value of
the common stock on the date of grant, which options vest in two equal annual
installments on the first and second anniversary dates of the grant. In
addition, each non-employee director receives an annual automatic grant of
options to purchase 10,000 shares of common stock at the fair market value of
the common stock on the date of grant, which options vest in full one year after
the date of grant.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

During fiscal 2004, the Compensation Committee of our Board of Directors
consisted of John M. Baumer and Frank Reddick. John B. Chickering, Jr., joined
our Compensation Committee in April, 2004. None of these individuals was one of
our officers or employees at any time during fiscal 2004. Mr. Reddick is a
partner at Akin Gump Strauss Hauer & Feld LLP, which provided legal services to
us during fiscal 2004 and is providing legal services to us in fiscal 2005.
Nevertheless, Mr. Reddick is not disqualified from serving as an independent
director on our Board under the Nasdaq National Market listing standard because
of the relatively small amount of fees we paid to Akin Gump Strauss Hauer & Feld
LLP in fiscal 2002, 2003 and 2004 in relation to our total revenues and the
total revenues of Akin Gump Strauss Hauer & Feld LLP for the same periods. None
of our executive officers served as a member of the board of directors or
compensation committee of any entity that has or has had one or more executive
officers serving as a member of our Board of Directors or Compensation
Committee.

We have employment agreements with Robert L. Antin, Arthur J. Antin and Tomas W.

                                       10

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information regarding beneficial ownership of our
common stock as of March 31, 2005, by:

     o    each of our directors;

     o    each of our Named Executive Officers;

     o    all of our directors and Named Executive Officers as a group; and

     o    all other stockholders known by us to beneficially own more than 5% of
          our outstanding common stock.

Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. In computing the number of shares
beneficially owned by a person and the percentage ownership of that person,
shares of common stock subject to options held by that person that are currently
exercisable or exercisable within 60 days of the date as of which this
information is provided, and not subject to repurchase as of that date, are
deemed outstanding. These shares, however, are not deemed outstanding for the
purposes of computing the percentage ownership of any other person.

Except as indicated in the notes to this table, and except pursuant to
applicable community property laws, each stockholder named in the table has sole
voting and investment power with respect to the shares shown as beneficially
owned by them. Percentage ownership is based on 82,234,320 shares of common
stock outstanding on March 31, 2005. Unless otherwise indicated, the address for
each of the stockholders listed below is c/o VCA Antech, Inc., 12401 West
Olympic Boulevard, Los Angeles, California 90064.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

RELATED PARTY TRANSACTIONS

Except as disclosed in this amendment to our annual report on Form 10K/A,
neither our directors or executive officers, nor any stockholder owning more
than five percent of our issued shares, nor any of their respective associates
or affiliates, had any material interest, direct or indirect, in any material
transaction to which we were a party during fiscal 2004, or which is presently
proposed.

We believe, based on our reasonable judgment, but without further investigation,
that the terms of each of the following transactions or arrangements between us
and our affiliates, officers, directors or stockholders which were parties to
the transactions were, on an overall basis, at least as favorable to us as could
then have been obtained from unrelated parties.

See "Employment and Severance Agreements" for a summary of employment agreements
with certain of our executive officers.

TRANSACTIONS WITH ZOASIS CORPORATION

We incurred marketing expense for vaccine reminders and other direct mail
services provided by Zoasis, an Internet based business that is majority owned
by Robert Antin, our Chief Executive Officer and Chairman. Art Antin, our Chief
Operating Officer, owns a 10% interest in Zoasis and a separate officer sold his
entire 1% interest in Zoasis prior to December 31, 2004 for less than $15,000.
The expense incurred was $946,000, $993,000 and $850,000 for 2004, 2003 and
2002, respectively. The pricing of these services is comparable to prices paid
by us to independent third parties for similar services.

STOCKHOLDERS' AGREEMENT AND PUBLIC OFFERINGS

On September 20, 2000, we entered into a stockholders agreement with each of our
then stockholders, under which each party to the stockholders agreement has
registration rights. In connection with these registration rights, we agreed to
pay any expenses associated with any demand registrations or piggyback
registrations.

In April 2004, pursuant to the registration rights granted in our stockholders
agreement, we filed a shelf registration on Form S-3 which registered for sale
the entire amount of shares of our common stock owned by an affiliate of Leonard
Green & Partners, LP, or 13,693,874 shares. On May 18, 2004, Leonard Green &
Partners, LP, sold 6,900,000 of these shares. Each of John M. Baumer, John G.
Danhakl and Peter J. Nolan is a partner of Leonard Green & Partners and served
as one of our directors at the time of this transaction. On August, 2004,
Leonard Green & Partners, LP, sold an additional 6,513,874 of these shares. John
M. Baumer is a partner of Leonard Green & Partners and served as one of our
directors at the time of this transaction. All share amounts identified herein
have been restated to reflect a 100% stock dividend paid on August 25, 2004.



                                       15



LEGAL SERVICES

The law firm of Akin Gump Strauss Hauer & Feld LLP currently provides, and
provided during fiscal year 2004, legal services to us. Frank Reddick, who
joined us as a director in February 2002, is a partner in Akin Gump Strauss
Hauer & Feld LLP.

POLICY ON AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT
SERVICES OF INDEPENDENT AUDITORS

The Audit Committee is responsible for appointing, setting the compensation of
and overseeing the work of the independent auditor. In recognition of this
responsibility, the Audit Committee has established a policy with respect to the
pre-approval of audit and permissible non-audit services and fees provided by
the independent auditor. Prior to March 2004, the Audit Committee specifically
pre-approved all audit services and fees. In March 2004, the Audit Committee
modified its pre-approval policy to require that all audit and permissible
non-audit services and fees be pre-approved by the Audit Committee unless those
services:

     o    will not result in a fee of greater than $5,000;

     o    were not recognized as audit, audit-related or tax services at the
          time of the engagement; and

     o    are promptly brought to the attention of the Audit Committee and
          approved by the Audit Committee (or its designated representatives)
          prior to the completion of the audit.



                                       16




Pursuant to the pre-approval policy, the Audit Committee's Chairman is delegated
the authority to pre-approve audit services and fees, provided he reports those
approvals at the next meeting of the Audit Committee. The term of any
pre-approval granted by the Audit Committee with respect to a given service is
twelve months. All fees in excess of pre-approved levels require specific
pre-approval by the Audit Committee. All audit or permissible non-audit services
provided to us in 2004 were approved by the Audit Committee.
