SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION On September 26, 2005, AHI, BWP Acquisition, Inc., a Delaware corporation and wholly-owned subsidiary of AHI (the "Merger Sub") and Party City entered into an Agreement and Plan of Merger (the "Merger Agreement") which provides that, subject to certain conditions, Merger Sub will be merged with and into Party City (the "Merger"), with Party City continuing as the surviving corporation after the Merger (the "Surviving Corporation"). In connection with the Merger Agreement, as a condition to the willingness of AHI to enter into the Merger Agreement, and as an inducement and in consideration therefore, AHI entered into a Voting Agreement, dated as of September 26, 2005 (the "Voting Agreement"), with Michael E. Tennenbaum, Tennenbaum Capital Partners, LLC, Tennenbaum & Co., LLC, Special Value Bond Fund, LLC, Special Value Absolute Return Fund, LLC and Special Value Bond Page 9 of 17 pages Fund II, LLC (the "Principal Stockholders"). By reason of AHI's entering into the Voting Agreement with the Principal Stockholders, AHI may be deemed to have acquired beneficial ownership of the shares of Party City Common Stock that are the subject of the Voting Agreement pursuant to Rule 13d-3(a)(1). By virtue of their direct and indirect ownership of all of AHI's capital stock, AAH, Fund V, Fund VI and Berkshire Investors may be deemed to have acquired beneficial ownership of the shares of Party City Common Stock that are the subject of the Voting Agreement. The transactions contemplated by the Voting Agreement do not require the expenditure of any funds. AHI anticipates that it will fund the transactions contemplated by the Merger Agreement through a combination of debt and equity financing. ITEM 4. PURPOSE OF TRANSACTION Merger Agreement As noted in Item 3 above, pursuant to the Merger Agreement, in order for AHI to fulfill its overall purpose of acquiring 100% of the outstanding common stock of Party City, AHI, Merger Sub and Party City have agreed to consummate the Merger in accordance with and subject to the terms and conditions of the Merger Agreement. At the effective time of the Merger (the "Effective Time") and as a result of the Merger, each share of common stock of Party City issued and outstanding immediately prior to the Effective Time (other than shares owned by AHI or Merger Sub, shares owned by any direct or indirect wholly-owned subsidiary of Party City and any dissenting shares whose holders have perfected their rights to dissent as described in the Merger Agreement) shall be automatically converted into the right to receive seventeen dollars and fifty cents ($17.50) in cash, without interest (the "Merger Consideration"). As of the Effective Time, all such shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and subject to rights of dissenting shares under the Merger Agreement, each holder of a certificate representing any such shares shall cease to have any rights with respect thereto except the right to receive Merger Consideration upon the surrender of such certificate in accordance with the Merger Agreement, without interest. Completion of the Merger is subject to the satisfaction of a number of conditions, including the receipt of regulatory approvals and approval of the Merger Agreement by a vote of the holders of not less than a majority of the outstanding shares of common stock of Party City. Voting Agreement As noted in Item 3 above, in connection with the Merger Agreement, as a condition to the willingness of AHI to enter into the Merger Agreement, and as an inducement and in consideration therefore, on September 26, 2005, AHI entered into the Voting Agreement with the Principal Stockholders. Note that our description of the terms of the Voting Agreement focuses on voting provisions and is not a complete description of the Voting Agreement. Please refer to the text of the Voting Agreement incorporated by reference herein. Pursuant to the Voting Agreement, the Principal Stockholders have agreed that, during the period from and including September 26, 2005 through and including the earliest to occur of (i) the Effective Time, (ii) the termination of the Merger Agreement in accordance with its terms, or (iii) written notice of termination of the Voting Agreement by AHI to the Principal Stockholders (the "Voting Period"), they will vote (or cause to be voted) with respect to the Covered Shares beneficially owned by them as of the applicable record date, at any meeting of the stockholders of the Company, however called, or at any adjournment thereof or in any other circumstances upon which a vote, consent or other approval (including by written consent) is sought, the Principal Stockholder shall (i) when a Page 10 or 17 pages meeting is held, appear at such meeting or otherwise cause the Covered Shares to be counted as present thereat for the purpose of establishing a quorum and (ii) vote (or cause to be voted) in person or by proxy the Covered Shares in favor of the approval of the Merger, the Merger Agreement and the transactions contemplated by the Merger Agreement; and (iii) vote (or cause to be voted) the Covered Shares against any extraordinary corporate transaction (other than the Merger), such as a merger, consolidation, business combination, tender or exchange offer, reorganization, recapitalization, liquidation, sale or transfer of a material amount of the assets or securities of Party City or any of its subsidiaries (other than pursuant to the Merger) or any other Takeover Proposal (as defined below). "Covered Shares" means all of the shares of Common Stock of which the Principal Stockholders were beneficial owners as of September 26, 2005, as well as any securities issued or exchanged with respect to such shares of Common Stock upon any recapitalization, reclassification, merger, consolidation, spin-off, partial or complete liquidation, stock dividend, split-up or combination of the securities of Party City or any other change in Party City's capital structure or securities of which such stockholder acquires beneficial ownership after the date of the Voting Agreement and prior to the termination of the Voting Agreement, whether by purchase, acquisition, or upon exercise of options, warrants, conversion of other convertible securities or otherwise. "Takeover Proposal" means any inquiry, proposal or offer relating to (A) any business combination with or any direct or indirect acquisition, in a single transaction or a series of transactions and whether by way of a merger, consolidation, business combination, reorganization, share exchange, sale of assets, recapitalization, liquidation, dissolution or similar transaction or otherwise, of (i) Party City, (ii) twenty-five (25) percent or more of any class of Party City's outstanding shares of capital stock or any other voting securities of the Party City or its subsidiaries (iii) 25% or more of the fair market value of the assets of Party City and its subsidiaries taken as a whole; (B) any tender offer (including a self-tender offer) or exchange offer, as defined pursuant to the Exchange Act, that, if consummated, would result in any Person or group beneficially owning 25% or more of any class of the capital stock of Party City or the filing with the Securities and Exchange Commission (the "Commission") of a Schedule TO or a registration statement under the Securities Act in connection therewith, or (C) any combination of the foregoing. In connection with their performance under the Voting Agreement, each of the Principal Stockholders irrevocably appointed AHI (and the president, secretary or any other designee of AHI) as his or its attorney-in-fact, to vote (or cause to be voted) the Covered Shares during the Voting Period to the extent described above. The proxy and power of attorney granted pursuant to the Voting Agreement shall terminate automatically upon termination of the Voting Agreement. Each of the Principal Stockholders has agreed not to, other than pursuant to the terms of the Voting Agreement or the Merger Agreement and except with respect to item (ii) below, without the prior written consent of AHI or as otherwise provided in the Voting Agreement, during the term of the Voting Agreement, such Principal Stockholder agreed to not, directly or indirectly, (i) grant any proxies or enter into any voting trust or other agreement or arrangement with respect to the voting of any Covered Shares or (ii) sell, pledge, assign, transfer, encumber or otherwise dispose of (including by merger, Page 11 of 17 pages consolidation or otherwise by operation of law), or enter into any contract, option or other arrangement or understanding with respect to the direct or indirect assignment, transfer, encumbrance or other disposition of (including by merger, consolidation or otherwise by operation of law), any Covered Shares. The Principal Stockholders and AHI delivered joint written instructions to Party City and Party City's transfer agent stating that the owned shares subject to the Voting Agreement may not be sold, transferred, pledged, assigned, hypothecated, tendered or otherwise disposed of in any manner without the prior written consent of Parent or except in accordance with the terms and conditions of the Voting Agreement. If any Covered Shares are acquired after the date of the Voting Agreement by a Stockholder, the foregoing instructions shall be delivered upon acquisition of such Covered Shares. Under the terms of the Voting Agreement, AHI can direct the Principal Stockholder to exercise the warrant to purchase 2,496,000 shares, at any time prior to the record date of the special meeting of shareholders. The voting provisions of the Voting Agreement will terminate upon the earliest to occur of (i) the Effective Time, (ii) the termination of the Merger Agreement in accordance with its terms, or (iii) written notice of termination of the Voting Agreement by AHI to the Principal Stockholders as provided therein. Pursuant to the Merger Agreement, immediately prior to the Effective Time, the directors of Merger Sub immediately prior to the Effective Time will be the initial directors of the surviving corporation. The officers of Party City immediately prior to the Effective Time shall be the officers of the surviving corporation. Additionally, at the Effective Time, the certificate of incorporation and bylaws of Merger Sub shall be the certificate of incorporation and bylaws of the Surviving Corporation. Following the consummation of the Merger, AHI intends that the Common Stock will be delisted from NASDAQ and will become eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended. The foregoing summaries of the Merger Agreement and the Voting Agreement are qualified in their entirety by reference to these agreements, copies of which are incorporated herein by reference to Exhibits 2.1 and 10.1 of Party City's 8-K filed with the Commission on September 27, 2005. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER As a result of the Voting Agreement, as of September 26, 2005, the Reporting Persons may be deemed to beneficially own 3,270,481 shares of Common Stock, 58,000 shares of Common Stock issuable upon the exercise of certain options and 2,496,000 shares of Common Stock issuable upon exercise of certain warrants, which represents approximately 29.3% of outstanding common stock, based on 17,319,386 shares of Common Stock issued and outstanding as of September 26, 2005 together with the 2,554,000 shares issuable upon exercise of certain stock options and warrants, which number is based on the representation regarding outstanding shares of Common Stock made by Party City in the Merger Agreement. The Reporting Persons share voting power over the shares beneficially owned pursuant to the Voting Agreement. To the best knowledge of the Reporting Persons, other than as set forth above, none of the Berkshire Principals or the executive officers or directors of any Reporting Person beneficially owns any shares of Party City Common Stock. Under the terms of the Voting Agreement, AHI can direct the Principal Stockholder to exercise the warrant to purchase 2,496,000 shares, at any time prior to the record date of the special meeting of shareholders. Page 12 of 17 Pages By virtue of the relationships described herein, the Reporting Persons may be deemed to constitute a "group" within the meaning of Rule 13d-5 under the Exchange Act. As a member of a group, each Reporting Person may be deemed to share voting and dispositive power with respect to, and therefore beneficially own, the shares beneficially owned by members of the group as a whole. The filing of this Statement shall not be construed as an admission that the Reporting Persons beneficially own those shares held by any other members of the group. As the ultimate general partner of Fund V, Fifth Berkshire may be deemed to beneficially own the securities subject to the Voting Agreement. The filing of this statement shall not be construed as an admission that Fifth Berkshire is, for the purpose of Section 13(d) of the Exchange Act, the beneficial owner of such securities. As the ultimate general partner of Fund VI, Sixth Berkshire may be deemed to beneficially own the securities subject to the Voting Agreement. The filing of this statement shall not be construed as an admission that Sixth Berkshire is, for the purpose of Section 13(d) of the Exchange Act, the beneficial owner of such securities. By virtue of their positions as managing members of Fifth Berkshire, Sixth Berkshire and Berkshire Investors the Berkshire Principals may be deemed to possess indirect beneficial ownership of the securities beneficially owned by Fund V, Fund VI or Berkshire Investors. None of the Berkshire Principals, acting alone, however, has voting or investment power with respect to the shares beneficially owned by the Fund V, Fund VI or Berkshire Investors, and, as a result, each Berkshire Principal disclaims beneficial ownership of such securities. Except as described above, none of the Reporting Persons, nor, to the best knowledge of the Reporting Persons, none of the Berkshire Principals or the executive officers or directors of any Reporting Person, has effected any transactions in the securities of Party City during the past sixty days.
