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 "Merger Agreement"), with New York Stock Exchange, 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 Merger Agreement, the --------------------------- --------------------------- 03957A104 Page 12 of 22 --------------------------- --------------------------- 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. This Amendment No. 1 is being 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 "Support Agreement"), with NYSE to induce NYSE to enter into the Merger Agreement. The 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 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 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 Company Merger Agreement), (v) change in the capital structure of the Company and (vi) other action that --------------------------- --------------------------- 03957A104 Page 13 of 22 --------------------------- --------------------------- would reasonably be expected to impede, delay, postpone or interfere with the Proposed Transaction or that would result in a breach of the Merger Agreement by the Company that would reasonably be expected to materially adversely affect the Company. In the event the 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 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 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 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 Merger Agreement is terminated under circumstances requiring the Company to pay a termination fee and reimburse expenses of NYSE --------------------------- --------------------------- 03957A104 Page 14 of 22 --------------------------- --------------------------- pursuant to the terms of the 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 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 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 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 five-year period following the consummation of the Company Merger, if any, the GA Signatories agreed not to sell or transfer any shares of common 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 third 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, (ii) upon and following the fourth anniversary of the Closing Date, the GA Signatories will be able to sell or transfer another one-third of the Locked-Up Shares, (iii) upon and following the fifth anniversary of the Closing Date, the GA Signatories will be able to sell or transfer the remaining one-third of the Locked-Up Shares and (iv) if the Board of Directors of Holdco releases from contractual transfer restrictions any shares of Holdco --------------------------- --------------------------- 03957A104 Page 15 of 22 --------------------------- --------------------------- 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. If on or prior to the first anniversary of the Closing Date the Board of Directors of Holdco has not authorized or effected at least one release of shares of Holdco Common Stock from contractual transfer restrictions (other than a release of shares of Holdco Common Stock held by GSP), then the GA Signatories will have a demand right (a "Demand Right"), exercisable once during any time between the first and second anniversaries of the Closing Date, to require Holdco to remove the transfer restrictions from up to one-third of the Locked-Up Shares. If on or prior to the second anniversary of the Closing Date the Board of Directors of Holdco has not authorized or effected at least two releases of shares of Holdco Common Stock from contractual transfer restrictions (other than a release of shares of Holdco Common Stock held by GSP), then the GA Signatories will have a Demand Right, exercisable once during any time between the second and third anniversaries of the Closing Date, to require Holdco to remove the transfer restrictions from all but one-third of the Locked-Up Shares. REGISTRATION RIGHTS. Whenever the GA Signatories exercise a Demand Right, the GA Signatories will have the right to simultaneously demand that Holdco effect the registration under the Securities Act of 1933, as amended (the "Securities Act"), of all or any portion of the shares of Holdco Common Stock that are released pursuant to the exercise of the Demand Right. In addition, if Holdco proposes to file a registration --------------------------- --------------------------- 03957A104 Page 16 of 22 --------------------------- --------------------------- statement under the Securities Act at any time following the Closing Date but prior to the expiration of the transfer restrictions described above 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 any other stockholders of Holdco participating in such registered offering. The foregoing summaries of the Merger Agreement and the Support Agreement are qualified in their entirety by reference to Exhibits 3 and 4, each of which is incorporated herein by reference. ITEM 5.
