stock of Archipelago, 14,039 shares of common stock of Archipelago and no
shares of common stock of Archipelago. As a result of the closing of Merger on

---------------------------                          ---------------------------


         On July 20, 2005, GAP 77, GAPCO II, GapStar, GAP-W and KG
(collectively, the "GA Signatories") entered into an Amended and Restated
Support and Lock-Up Agreement (the "Support Agreement") with the NYSE pursuant
to which the GA Signatories agreed not to sell or transfer any shares of
Common Stock during the three-year period following the Closing Date except as
follows: (i) upon and following the first anniversary of the Closing Date, the
GA Signatories will be able to sell or transfer one-third of the Locked-Up
Shares, to the extent such amount of Locked-Up Shares have not previously been
released as described in clause (iv) below, (ii) upon and following the second
anniversary of the Closing Date, the GA Signatories will be able to sell or
transfer another one-third of the Locked-Up Shares, to the extent such amount
of Locked-Up Shares have not previously been released as described in clause
(iv) below, (iii) upon and following the third anniversary of the Closing
Date, the GA Signatories will be able to sell or transfer the remaining
one-third of the Locked-Up Shares, so that in any event the GA Signatories
will be able to sell or transfer all Locked-Up Shares on and after the third
anniversary of the Closing Date, and (iv) if the Company's Board of Directors
releases from contractual transfer restrictions any shares of Common Stock
that were issued in the Merger (other than those shares of Common Stock issued
to GSP, LLC ("GSP"), an entity affiliated with Mr. Gerald D. Putnam), then a
proportionate number of Locked-Up Shares that remain subject to the transfer
restrictions described above will similarly be released.

         If the Company proposes to file a registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), at any time
following the Closing Date but prior to the expiration of the transfer
restrictions described above in respect of an offering to be made for its own
account, and the Company decides to permit

62949W103                                                          Page 15 of 24
---------------------------                          ---------------------------


certain of its stockholders to participate in such registered offering, then
the GA Signatories will have the right to participate in the registered
offering on a pro rata basis with the other stockholders of the Company
participating in such registered offering. In addition, if the Company
proposes to file a registration statement under the Securities Act at any time
following the Closing Date but prior to the expiration of the transfer
restrictions described above in respect of an offering to be made for the
account of entities affiliated with The Goldman Sachs Group, Inc., consisting
of GS Archipelago Investment, L.L.C., SLK-Hull Derivatives LLC and Goldman
Sachs Execution and Clearing, L.P., or any holder of the Common Stock who was
a member of the NYSE immediately prior to the mergers described above, then
the GA Signatories will also have the right to participate in such registered
offering on a pro rata basis with the other stockholders of the Company
participating in such registered offering. If the GA Signatories have not had
the right to participate in at least one offering on or prior to the first
anniversary of the Closing Date, then the GA Signatories shall have the right
(a "Registration Right"), exercisable once during the period between the first
and second anniversaries of the Closing Date, to demand that the Company
effect the registration under the Securities Act of all or any portion of the
Common Stock held by the GA Signatories that are then no longer subject to the
restrictions on transfer described above. If the GA Signatories have not had
the right to participate in at least two offerings on or prior to the second
anniversary of the Closing Date, then the GA Signatories shall have a
Registration Right, exercisable once during the period between the second and
third anniversaries of the Closing Date, to demand that the Company effect the
registration under the Securities Act of all or any portion of the Common
Stock held by the GA Signatories that are then no longer subject to the
restrictions on transfer described above.

62949W103                                                          Page 16 of 24
---------------------------                          ---------------------------


Finally, the GA Signatories have a Registration Right, exercisable once during
the period between the third and fourth anniversaries of the Closing Date, to
demand that the Company effect the registration under the Securities Act of
all or any portion of the Common Stock held by the GA Signatories that are
then no longer subject to the restrictions on transfer described above. The
foregoing summary of the Support Agreement is qualified in its entirety by
reference to Exhibit 4 which is incorporated by reference herein.

         On October 20, 2005, the GA Signatories entered into a Registration
Rights Agreement (the "Registration Rights Agreement") with the NYSE and the
Company providing for additional rights and obligations in connection with
certain registration rights granted by the NYSE and the Company pursuant to
the Support Agreement described above. Under the Registration Rights
Agreement, the Company has the right to postpone effecting a registration
requested by the GA Signatories pursuant to the Support Agreement for a period
of time not to exceed 45 days if the Company determines in good faith that
effecting the registration would materially and adversely affect an offering
of securities of the Company (the preparation of which has already commenced)
or would require the Company to disclose material non-public information (the
disclosure of which during such period would not be in the best interests of
the Company). The Company may not postpone such a registration more than twice
during any period of 12 consecutive months.

         Pursuant to the Registration Rights Agreement, the GA Signatories
will be liable for their portion of the registration and filing fees payable
to the Securities and Exchange Commission in connection with any registered
offering of the Company common stock effected pursuant to the Registration
Rights Agreement (with such portion



---------------------------                          ---------------------------

based on the number of shares of the Common Stock being sold by or on behalf
of the GA Signatories in the offering). The Company will be liable for all
other registration-related expenses of such offering, other than the
underwriter's discounts and commissions related to the shares of the Common
Stock sold by or on behalf of the GA Signatories in such offering, which
discounts and commissions will be the responsibility of the GA Signatories. If
any of the Company's stockholders participate in a registered offering with
the GA Signatories, the Company may require such stockholders to pay for their
portion of some or all of the expenses of such offering (with such portion
based on the number of shares of the Common Stock being sold by or on behalf
of such stockholders in the offering). If the Company imposes this
requirement, the GA Signatories will be liable for their portion of the same
registration expenses (with such portion based on the number of shares of the
Common Stock being sold by or on behalf of the GA Signatories in the
offering).

         The GA Signatories also have the right to participate in certain
registered offerings of the Common Stock to the extent that such persons
continue to hold the Common Stock subject to the transfer restrictions imposed
by the Support Agreement. Specifically, if the Company proposes an offering of
the Common Stock for its own account and decides to permit certain of its
stockholders to participate in that registered offering, then the GA
Signatories will also be entitled to participate in that registered offering
pro rata with the other stockholders that are participating in the offering.
Moreover, if the Company agrees to register an offering of the Common Stock
for any stockholder who was a NYSE member immediately prior to the mergers
contemplated by the Merger Agreement, then the GA Signatories will be entitled
to participate in that offering on equal terms and pro rata with the other
stockholders participating in the
