Filed by NYSE Group, Inc. Pursuant to Rule 425 under the Securities Act of 1933, as amended, and deemed filed pursuant to Rule 14a-12 of the Securities Exchange Act of 1934, as amended Subject Companies: New York Stock Exchange, Inc. Archipelago Holdings, Inc. (Commission File No. 001-32274) Date: November 14, 2005 On November 11, 2005, the New York Stock Exchange, Inc. issued the following bulletin to its members: * * * Special Membership Bulletin [LETTERHEAD OF RICHARD BERNARD] DATE: NOVEMBER 11, 2005 TO: NYSE MEMBERS FROM: RICHARD BERNARD RE: TRANSFER OF SEATS TO FAMILY MEMBERS AND GRANTOR RETAINED ANNUITY TRUSTS In response to requests from members wishing to take advantage of tax-planning opportunities associated with the anticipated NYSE-Archipelago merger, NYSE will be filing with the SEC for members to transfer their seats to family members and/or grantor retained annuity trusts, commonly known as GRATs. This plan, if approved, should create even greater tax planning flexibility for members than the previously announced plan, which was to permit transfers only to GRATs. Below is a Summary of Steps describing how to transfer NYSE seats first into a limited liability company (or "LLC") and then to transfer interests in the LLC to a GRAT and/or to family members. Each document required of a member or the member's legal counsel is underscored on first reference. Documents highlighted in bold must follow the NYSE form or contain provisions required by NYSE. After the Summary of Steps, there is information on how to submit the required documentation and the associated application and initiation fees. The final part of this Red Border concerns the impact of LLC structures on members who intend to vote in the merger via proxy. BACKGROUND. An amendment of the NYSE Constitution (previously approved by the members) and a rule change must become effective under SEC rules in order for NYSE to permit seats to be transferred to LLCs and for the LLC interests to be transferred to family members and/or placed in GRATs. We expect to file our proposal with the SEC in the next several days. Text of the Constitutional amendment, the current proposed form of rule, and a copy of this Red Border memorandum are available at www.nyse.com/nysellc. Members and their advisors are urged to check this webpage regularly for updates on the transfer of seats to LLCs and the transfer of LLC units to family members and GRATs. SUMMARY OF STEPS. If the filing becomes effective under SEC rules, the following steps will be necessary for any member wishing to transfer his or her seat to an LLC and to transfer LLC interests to family members and/or GRATs: (1) Preparation of a draft CERTIFICATE OF FORMATION for a single-owner, single-purpose LLC and a draft LLC AGREEMENT containing special provisions required by NYSE rules. (2) Preparation of a draft DESIGNATION OF MANAGER of the LLC. (3) If the seat is leased, preparation of a draft LEASE SUBSTITUTION AGREEMENT to be used to terminate any existing lease and create a new lease running from the LLC to the existing lessee which will terminate upon the merger. (4) Preparation of a draft MEMBERSHIP TRANSFER, ACKNOWLEDGEMENT AND RELEASE, to be used for purposes of effectuating the transfer of the seat to the LLC. (5) If the member plans to transfer LLC interests to one or more GRATs, preparation of one or more draft GRAT INSTRUMENTS, naming the initial Trustee thereof. (6) Preparation of a draft DEED OF GIFT in respect of each proposed transferee of LLC interests, specifying the interest to be transferred to each transferee. (7) Preparation of a draft TRANSFEREE AGREEMENT TO BE BOUND in respect of each proposed transferee of LLC interests. (8) Preparation of a draft QUALIFYING WRITTEN NOTICE TO AND WAIVER BY NYSE AND THE LLC MANAGER pertaining to the proposed transfer(s). (9) Preparation of a draft LETTER OF INSTRUCTION to be signed by the transferring member. (10) Preparation of legal counsel's FIRST-PHASE SUBMISSION LETTER and draft SECOND-PHASE SUBMISSION LETTER. The prescribed form of First-Phase Submission Letter (used in connection with submitting draft documents) includes a CERTIFICATE OF MEMBER, and the prescribed form of Second-Phase Submission Letter (used in connection with submitting executed documents that have been approved in draft by NYSE) includes a SUPPLEMENTAL CERTIFICATE OF MEMBER. (11) Preparation of a REV. FORM U4 (06-2003) in respect of the proposed LLC manager (unless the transferring NYSE member will be the manager of his or her LLC) and each proposed transferee of LLC interests (i.e., each GRAT trustee, other than the transferring member if he or she is the GRAT trustee, and each family member transferee) if the transfer would change or create control of the LLC within the meaning of NYSE Rule 2. (12) Submission to NYSE's designated legal counsel of the following documents: (a) First-Phase Submission Letter (b) Certificate of Member (with attached draft documents) (c) Rev. Form U4 (06-2003) for each transferee for which this submission is required 2 (d) Application fee ($5,000, by check payable to New York Stock Exchange, Inc.) (e) Initiation fee ($5,075, by check payable to New York Stock Exchange, Inc.) The Exchange will not charge a lease transition fee. The initiation fee will be refunded if the NYSE rule change permitting transfers to LLCs does not become effective or if NYSE denies a member's request to transfer his or her seat to an LLC. (13) If NYSE approves the request made in the First-Phase Submission Letter, issuance by NYSE of a Letter of Provisional Approval. (14) Formation of the LLC, execution of those documents identified above which were not executed in connection with the First-Phase Submission, and submission to NYSE's designated legal counsel of the following documents: (a) Second-Phase Submission Letter (b) Supplemental Certificate of Member (with attached copies of executed documents) (c) Membership Transfer, Acknowledgement and Release (executed) (d) Qualifying Written Notice to and Waiver by NYSE and the LLC Manager (duplicate originals) (not yet executed by NYSE) (e) Letter of Instruction (executed) (15) Issuance by NYSE of a Letter of Confirmation stating that the LLC has been substituted for the member and is a Limited Transfer Member of NYSE within the meaning of NYSE's Constitution and approving those transfers of LLC interests that require NYSE approval. NYSE APPROVAL OF TRANSFEREES OF LLC INTERESTS. A transferee of LLC interests will require NYSE approval (and as such will require the submission of Rev. Form U4 (06-2003) as described above) if the transferee will receive a controlling interest in the LLC or if the transferor will relinquish control. Generally speaking, an interest will be a controlling interest if it is 25% or more of the voting or profits interest in the LLC or if it includes a veto power over the LLC. For these purposes, transfers to multiple family members and/or GRATs ordinarily will not be aggregated for purposes of applying the 25% threshold, but those transfers may nonetheless require approval if they confer veto rights on any one or more transferees. Also, if the aggregate of proposed transfers would reduce the member's interest in the LLC to 50% or less, NYSE approval of the transferees will be required, even if no particular transferee will receive a controlling interest. DEFINITION OF FAMILY MEMBERS. For purposes of the merger, the term "family member" refers to a member's spouse, domestic partner, child, stepchild, grandchild, parent, parent-in-law, grandparent, uncle, aunt, cousin, nephew or niece. This definition is derived from "lock-up" provisions that will apply to NYSE Group, Inc. shares after the merger. Under the NYSE-Related Provisions of each LLC Agreement, the "lock-up" limitations on NYSE Group, Inc. shares will 3 apply to transfers of interests in the LLC as long as the LLC holds NYSE Group, Inc. shares subject to the "lock-up." REQUIRED DOCUMENTATION. In addition to the information already posted on NYSE's website, at www.nyse.com/nysellc, NYSE plans in the coming days to post on its website a prototype of the NYSE-Related Provisions that the rule, if approved, will require, together with prototypes of the documents which are identified above in bold, underscored type. All prototypes will be made available in Word and in PDF formats, other than Rev. Form U4 (06-2003), which will be available only in PDF format. All submissions must substantially follow the prototypes on the website or they will be rejected. Although NYSE has not promulgated proposed forms for the other required documents, NYSE urges members and their advisors to opt for straightforward documentation that will facilitate review by NYSE staff and outside counsel. Please note, as we have stated before, that NYSE's outside counsel fees incurred in the review of these documents will be billed back to members based on the amount of time spent on a particular member's LLC-related documentation. Each member agrees, by directing his or her counsel to submit the First-Phase Submission Letter, to assume the obligation to reimburse NYSE and its successors for these outside counsel fees. QUESTIONS. Questions concerning legal documentation should be directed to Alexander Lewis, Esq. (212-336-2825) or John Sare, Esq. (212-336-2760) at Patterson, Belknap, Tyler & Webb LLP. Questions concerning Rev. Form U4 (06-2003) disclosures should be directed to Steven L. Fuller, NYSE's Director of Membership Services (212-656-2071). SUBMISSION OF DOCUMENTS. Each phase of the submissions submitted first via email in a single PDF, emailed to NYSE's designated legal counsel, Patterson, Belknap, Tyler & Webb LLP, at nysellc@pbwt.com. Please do not use that email address for the submission of questions. A hard copy of each submission should be sent by regular mail, Federal Express or Express Mail to John Sare, Esq., Patterson, Belknap, Tyler & Webb LLP, 1133 Avenue of the Americas, New York, NY 10036. The hard copy should include a signed ORIGINAL of the First-Phase or Second-Phase Submission Letter (as appropriate) and Certificate of Member, together with all other originals and copies that are required. LIMITATIONS. We urge members to submit draft documentation, disclosures and executed documentation as soon as possible. However, NYSE offers no assurances that its review will be completed in advance of any particular date or event. Nor can NYSE offer any assurances when or if the proposed Rule and Constitutional amendment will become effective under SEC rules. NYSE has undertaken to facilitate the creation of GRATs solely as a courtesy and convenience to members and assumes no obligations or duties in so doing. NYSE may approve or disapprove documents in its discretion, including documents that follow the forms NYSE has provided. NYSE takes no position as to whether members should or should not transfer their seats to LLCs or whether members should or should not create GRATs, and neither NYSE nor its outside counsel is undertaking to provide legal, tax or financial advice to NYSE members. NYSE reserves the right, in its discretion, to change the procedures outlined in this memorandum at any time. Accordingly, NYSE disclaims any and all responsibility for members' legal fees or other costs or expenses associated with GRATs or LLCs, including any possible tax benefits which the member for any reason is unable to realize or to realize fully. PROXY VOTING. At the time of submission of the executed documentation, the LLC manager is urged to submit a merger-related proxy. Once NYSE issues its Letter of Confirmation, the LLC 4 manager's proxy will supersede any proxy previously submitted by the individual member who created the LLC. If a member is uncertain whether a Letter of Confirmation will be issued prior to the merger vote, he or she should submit his or her INDIVIDUAL proxy. A proxy submitted by an individual member will be accepted as a valid proxy if no Letter of Confirmation is issued in advance of the merger BUT WILL BE DISREGARDED if a Letter of Confirmation is issued. Because abstentions will be counted as votes against the merger, members who favor the merger should ensure that managers of LLCs they create either appear in person to vote or provide a proxy on behalf of the LLC. 5 IMPORTANT ACQUISITION INFORMATION WITH RESPECT TO THE MERGER In connection with the proposed merger of the New York Stock Exchange, Inc.
