SECURITY AND ISSUER. ITEM 1 IS HEREBY AMENDED AND RESTATED IN ITS ENTIRETY AS FOLLOWS: This Amendment No. 2 to Schedule 13D ("Amendment No. 2") is filed by the undersigned to amend and supplement the Schedule 13D, dated August 16, 2004 (the "Original Schedule 13D"), as amended by Amendment No. 1 thereto, dated April 26, 2005 ("Amendment No. 1"), with respect to the shares of common stock, par value $0.01 per share (the "Common Stock"), of Archipelago Holdings, Inc., a Delaware corporation (the "Company"). The address of the principal executive office of the Company is 100 South Wacker Drive, Suite 1800, Chicago, Illinois 60606. ITEM 2. IDENTITY AND BACKGROUND. Unchanged. --------------------------- --------------------------- 03957A104 Page 10 of 21 --------------------------- --------------------------- ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Unchanged. ITEM 4. PURPOSE OF TRANSACTION. ITEM 4 IS HEREBY AMENDED AND RESTATED IN ITS ENTIRETY AS FOLLOWS: The Reporting Persons acquired beneficial ownership of the shares of Common Stock described in this Schedule 13D for investment purposes. The Reporting Persons may, from time to time, make additional purchases of Common Stock either in the open market or in private transactions, depending upon the Reporting Persons' evaluation of the Company's business, prospects and financial condition, the market for the Common Stock, other opportunities available to the Reporting Persons, general economic conditions, stock market conditions and other factors. Depending upon the factors noted above and subject to the limitations described below, the Reporting Persons may decide to hold or dispose of all or part of their investment in the Common Stock. The Company entered into an Agreement and Plan of Merger, dated as of April 20, 2005 (the "Original Merger Agreement"), with New York Stock Exchange, --------------------------- --------------------------- 03957A104 Page 11 of 21 --------------------------- --------------------------- Inc., a New York Type A not-for-profit corporation ("NYSE"), and such other persons that become signatories thereto pursuant to the terms thereof. Pursuant to the Original Merger Agreement, the Company and NYSE agreed, among other things, to combine their businesses by (i) merging the Company (the "Company Merger") with a wholly-owned subsidiary of NYSE Group, Inc. ("Holdco"), a newly created, for-profit holding company and (ii) merging the successor to NYSE (the "NYSE Merger") with another wholly-owned subsidiary of Holdco. Amendment No. 1 was filed as a result of GAP 77, GAP-W, GapStar, GAPCO II and KG (collectively, the "GA Signatories") entering into a Support and Lock-Up Agreement, dated as of April 20, 2005 (the "Original Support Agreement"), with NYSE to induce NYSE to enter into the Original Merger Agreement. On July 20, 2005, the Company and NYSE entered into a definitive Amended and Restated Agreement and Plan of Merger ("Amended Merger Agreement") that amended and restated certain provisions of the Original Merger Agreement. Amendment No. 2 is being filed as a result of the GA Signatories entering into an Amended and Restated Support and Lock-up Agreement, dated as of July 20, 2005 (the "Amended Support Agreement"), with NYSE to induce NYSE to enter into the Amended Merger Agreement. The Amended Support Agreement provides as follows: VOTING. Subject to the limitations on voting set forth in the Company's Certificate of Incorporation, the GA Signatories agreed, among other things, to vote all of the shares of Common Stock held by the GA Signatories in favor of the Company Merger, the Amended Merger Agreement and the other transactions contemplated thereby (the "Proposed Transaction") and against any (i) other proposal to acquire the Company, any of its major subsidiaries, 10% or more of any class of equity securities or voting power or --------------------------- --------------------------- 03957A104 Page 12 of 21 --------------------------- --------------------------- 10% or more of the consolidated gross assets of the Company or 50% or more of any class of equity securities or voting power of any major subsidiary of the Company (any such proposal an "Acquisition Proposal"), (ii) other proposal for a merger, consolidation, sale of assets, business combination, share exchange, reorganization or recapitalization of the Company or any of its subsidiaries that is made in opposition to, or in competition with, the Proposed Transaction, (iii) liquidation or winding up of the Company, (iv) extraordinary dividend by the Company (other than as permitted by the Amended Merger Agreement), (v) change in the capital structure of the Company and (vi) other action that would reasonably be expected to impede, delay, postpone or interfere with the Proposed Transaction or that would result in a breach of the Amended Merger Agreement by the Company that would reasonably be expected to materially adversely affect the Company. In the event the Amended Merger Agreement is terminated under circumstances requiring the Company to pay a termination fee and reimburse expenses of NYSE pursuant to the terms of the Amended Merger Agreement, then for a period of fifteen months after such termination the GA Signatories agreed to vote all shares of Common Stock held by the GA Signatories (subject to (x) a cap equal to 15.8% of the total number of shares of Common Stock then issued and outstanding and (y) the limitations on voting set forth in the Company's Certificate of Incorporation) against any Acquisition Proposal. NON-SOLICITATION. Until the Proposed Transaction is consummated or the Amended Merger Agreement is terminated in accordance with its terms (other than under circumstances where the Company is required to pay a termination fee and reimburse expenses of NYSE), the GA Signatories agreed not to make, or in any manner participate in, directly --------------------------- --------------------------- 03957A104 Page 13 of 21 --------------------------- --------------------------- or indirectly, any "solicitation" of proxies or powers of attorney, or seek to advise or influence any person with respect to the voting of, any shares of Common Stock intended to facilitate any Acquisition Proposal with respect to the Company or to cause the failure of the stockholders of the Company to approve and adopt the Proposed Transaction. In addition, the GA Signatories agreed that neither they, nor their advisors, will solicit or knowingly encourage any inquiries or proposals relating to any Acquisition Proposal or approve or recommend any Acquisition Proposal. In the event the Amended Merger Agreement is terminated under circumstances requiring the Company to pay a termination fee and reimburse expenses of NYSE pursuant to the terms of the Amended Merger Agreement, then for a period of fifteen months after such termination the GA Signatories agreed to refrain from encouraging, facilitating or supporting in any way any Acquisition Proposal. TRANSFER RESTRICTIONS. Until the Proposed Transaction is consummated or the Amended Merger Agreement is terminated in accordance with its terms (other than under circumstances where the Company is required to pay a termination fee and reimburse expenses of NYSE), the GA Signatories agreed not to sell or transfer any shares of Common Stock held by the GA Signatories. In the event the Amended Merger Agreement is terminated under circumstances requiring the Company to pay a termination fee and reimburse expenses of NYSE pursuant to the terms of the Amended Merger Agreement, then for a period of fifteen months after such termination the GA Signatories agreed not to sell or transfer any shares of Common Stock held by the GA Signatories. During the three-year period following the consummation of the Company Merger, if any, the GA Signatories agreed not to sell or transfer any shares of common --------------------------- --------------------------- 03957A104 Page 14 of 21 --------------------------- --------------------------- stock of Holdco ("Holdco Common Stock") received by the GA Signatories in the Company Merger (the "Locked-Up Shares"), except as follows: (i) upon and following the first anniversary of the closing date of the Company Merger (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 Board of Directors of Holdco releases from contractual transfer restrictions any shares of Holdco Common Stock that were issued in the NYSE Merger or the Company Merger (other than those shares of Holdco Common Stock issued to GSP, LLC ("GSP"), an entity affiliated with Mr. Gerald D. Putnam, the Chairman and Chief Executive Officer of the Company), then a proportionate number of Locked-Up Shares that remain subject to the transfer restrictions described above will similarly be released. REGISTRATION RIGHTS. If Holdco 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, --------------------------- --------------------------- 03957A104 Page 15 of 21 --------------------------- --------------------------- and Holdco decides to permit 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 Holdco participating in such registered offering. In addition, if Holdco 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 Holdco Common Stock who was a member of NYSE immediately prior to the mergers contemplated by the Amended Merger Agreement in respect of Holdco Common Stock issued in the NYSE Merger, then the GA Signatories will have the right to participate in such registered offering on a pro rata basis with the other stockholders of Holdco 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 Holdco effect the registration under the Securities Act of all or any portion of the Holdco 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 Holdco effect the registration under the Securities Act of all or any portion of the Holdco Common Stock held by the GA Signatories that are then no longer subject to the restrictions on transfer described above. 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 Holdco effect the registration under the Securities Act of all or any portion of the Holdco Common Stock held by the GA Signatories that are then no longer subject to the restrictions on transfer described above. --------------------------- --------------------------- 03957A104 Page 16 of 21 --------------------------- --------------------------- The foregoing summaries of the Amended Merger Agreement and the Amended Support Agreement are qualified in their entirety by reference to Exhibits 3 and 4, each of which is incorporated herein by reference.
