                          Special Membership Bulletin

DATE:             MARCH 2, 2006

TO:               NYSE MEMBERS/HOLDERS OF TRADING LICENSES

FROM:             NELSON CHAI

SUBJECT:          TRADING LICENSE PROCEDURES


With the close of our merger with Archipelago March 7, NYSE Trading Licenses
will be required in order to trade on the NYSE beginning March 8. This
memorandum describes procedures for billing and other information related to the
launch of NYSE Trading Licenses.

Trading License holders will be required to pay a deposit of one month's Trading
License payment, which will be applied to the last month's Trading License
payment or to the Termination Fee for early termination, if applicable.
Otherwise, Trading License fees will be billed monthly. Members will receive a
bill in early April for 1) the March 8-March 31 period; 2) the month of April,
and; 3) a one-month deposit which will be applied to payment for the month of
December. Bills are payable on receipt.

Please note that only Member Organizations in good standing will be permitted to
receive Trading Licenses. ALL INVOICES SUBMITTED TO MEMBER ORGANIZATIONS DATED
DECEMBER 31, 2005 AND PRIOR, MUST BE FULLY PAID BEFORE A MEMBER ORGANIZATION
WILL BE PERMITTED TO RECEIVE ITS LICENSE(S). Lessee Members are reminded that
lease payments to Lessors should be made through and including March 7. Any
lease payments already made for the period beyond March 7 should be refunded to
Lessees.

In addition to these Trading License Billing procedures, Members and Member
Organizations are advised that NYSE Market will also implement the following
fees:

APPROVAL OF NEW MEMBER OR PRE-QUALIFIED SUBSTITUTE   $1,000.00
o    This fee will not apply to current NYSE Members who continue approved for
     Trading Floor access after the merger. From and after the merger, however,
     if any approved Member changes employment and continues as a Member with
     another Trading License holder, the new employer will be billed this fee.
     If a pre-qualified






     substitute changes employment and continues as a pre-qualified substitute
     with another Trading License holder, the new employer will be billed this
     fee.
o    Member Organizations must give five business days' notice to Membership
     Services before a pre-qualified substitute may appear on the floor.

BADGE MAINTENANCE FEE                                           $250.00
o    This fee will be charged annually for each active Member of a Member
     Organization, and for each pre-qualified substitute.

LICENSE TRANSFER FEE                                            $1,000.00
o    This fee is charged when an existing Trading License is to be transferred
     to a permitted transferee, namely, another Member Organization that is an
     affiliate or a successor to the business of the first Trading License
     holder within the meaning of Rule 300(a).

All Member Organizations that require additional Trading Licenses beyond those
they obtained in the December auction may purchase them throughout the year at
an annual rate of $54,219, which is 10% above the annual auction price, subject
to proration for the amount of time remaining in the year, and subject to the
ceiling of 1,366 Trading Licenses outstanding at any time. The forms for
applying for additional licenses are available at www.nyse.com.

Should you have any questions about these policies and fees, please contact
Steve Fuller in Membership Services at (212) 656-2071. For all inquiries related
to billing, please contact Andrew Brandman at (212) 656-2262.

FORWARD-LOOKING STATEMENTS
Certain statements in this press release may contain forward-looking information
regarding the NYSE and Archipelago and the combined company after the completion
of the transactions that are intended to be covered by the safe harbor for
"forward-looking statements" provided by the Private Securities Litigation
Reform Act of 1995. These statements include, but are not limited to, the
benefits of the business combination transaction involving NYSE and Archipelago,
including future financial and operating results, the new company's plans,
objectives, expectations and intentions and other statements that are not
historical facts. Such statements are based upon the current beliefs and
expectations of NYSE's and Archipelago's management and are subject to
significant risks and uncertainties. Actual results may differ from those set
forth in the forward-looking statements.

The following factors, among others, could cause actual results to differ from
those set forth in the forward-looking statements: the ability to obtain
governmental approvals of the transaction on the proposed terms and schedule;
the risk that the businesses will not be integrated successfully; the risk that
the cost savings and any other synergies from the transaction may not be fully
realized or may take longer to realize than expected; disruption from the
transaction making it more difficult to maintain relationships with customers,
employees or suppliers; competition and its effect on pricing, spending,
third-party relationships and revenues; social and political conditions such as
war, political unrest or terrorism; general economic conditions and normal
business uncertainty. Additional risks and factors are identified in
Archipelago's filings with the Securities Exchange Commission, including its
Report on Form 10-K for the fiscal year ending December 31, 2004 which is
available on Archipelago's website at http://www.Archipelago.com, and the

only as of the date of this document. Except for any obligation to disclose
material information under the Federal securities laws, none of the NYSE,
Archipelago or the combined company after the completion of the transactions
undertake any obligation to release publicly any revisions to any
forward-looking statements to reflect events or circumstances after the date of
this document.
