ITEM 4 PURPOSE OF TRANSACTION The following is hereby added to the end of Item 4: The foregoing is qualified in its entirety by the following: Orphan Medical, Inc., a Delaware corporation (the "Company"), Jazz Pharmaceuticals, Inc., a Delaware corporation ("Buyer"), and Twist Merger Sub, Inc., a Delaware corporation ("Sub") entered into a Merger Agreement as of April 18, 2005 (the "Merger Agreement", attached hereto as Exhibit 9 and incorporated by reference herein), which provides for, upon the terms and subject to the conditions set forth therein, the merger of Sub with and into the Company (as set forth in the Merger Agreement) in exchange for a cash payment for all of the issued and outstanding shares of capital stock of the Company (the "Merger"). The Voting Agreement provides that approval of the Merger Agreement by (i) the holders of a majority of the issued and outstanding shares of the Company's Common Stock, $0.01 par value per share, voting together with the holders of the Company's Senior Convertible Preferred Stock, $0.01 par value per share ("Senior Preferred Stock"), voting on an as converted basis and (ii) the holders of a majority of the issued and outstanding shares of Senior Preferred Stock, voting as a separate class, among other things, is required in order to consummate the transactions contemplated by the Merger Agreement.

UBS further agrees not to enter into any agreement or understanding with any person to vote or give instructions in any manner inconsistent with or violative of the foregoing terms. Proxy.

Transfer of Subject Shares. Except as otherwise contemplated by the Merger Agreement, until the termination of the Voting Agreement, UBS agrees that it will be the beneficial owner of all of its Subject Shares and will hold such Subject Shares free and clear of all Liens and will not, directly or indirectly, without the prior written consent of Buyer: (a) offer for sale, sell, transfer, tender, pledge, encumber, assign or otherwise in any way dispose of, or enter into any contract, option or other agreement (oral or written) with respect to or consent to the offer for sale, sale, transfer, tender, pledge, encumbrance, assignment or any other disposition of, any or all of such Stockholder's Subject Shares, or any interest therein; (b) grant any proxies or powers of attorney, deposit any of the Subject Shares into a voting trust or enter into a voting agreement with respect to any of the Subject Shares; (c) take any action that would reasonably be expected to have the effect of preventing or disabling such Stockholder from performing its obligations under this Agreement or making any representation or warranty of such contained in this Agreement untrue or incorrect; or (d) enter into any agreement or arrangement providing for any of the actions described in clause (a), (b) or (c) above. Termination. The Voting Agreement terminates upon the earliest to occur of (i) the Merger Effective Time, (ii) the valid termination of the Merger Agreement in accordance with its terms, (iii) the execution of any amendment to the Merger Agreement that modifies the amount, form or timing of payment of the Merger Consideration in a manner adverse to any Stockholder without the prior written consent of such Stockholder or (iv) the mutual agreement of the parties hereto. Page 9 of 13 pages Certain Events. UBS agrees that the Voting Agreement and its obligations thereunder shall attach to its Subject Shares and shall be binding upon any person or entity to which legal or beneficial ownership of such Subject Shares shall pass, whether by operation of law or otherwise, including, without limitation, UBS' successors. Notwithstanding any transfer of Subject Shares, the transferor shall remain liable for the performance of all its obligations under the Voting Agreement. The preceding summary of certain provisions of the Voting Agreement is not intended to be complete and is qualified in its entirety by reference to the full text of the Voting Agreement and the Merger Agreement, copies of which are filed as exhibits hereto and are incorporated herein by reference. ITEM 5 INTEREST IN SECURITIES OF THE ISSUER Item 5 is hereby deleted in its entirety and replaced with the following: a. UBS is the beneficial owner of 289,986 shares of Common Stock, 8,706 shares of Senior Convertible Preferred Stock and 4,420 shares of Series B Convertible Preferred Stock which shares of Senior Convertible Preferred Stock and Series B Convertible Preferred Stock are currently convertible into an aggregate of 1,749,533 shares of Common Stock. In addition, UBS beneficially owns up to 2,050 shares of non-voting Series C Convertible Preferred Stock or 315,385 shares of Series D Non-Voting Convertible Preferred Stock or any combination thereof up to a maximum aggregate purchase price of $2,050,000 and 282,353 shares of Series D Non-Voting Convertible Preferred Stock, such shares are issuable upon exercise of the respective warrants. Upon issuance, such shares would currently be convertible into 315,385 shares and 282,353 shares, respectively, of Common Stock, subject to anti-dilution adjustments. UBS also beneficially owns 40,000 shares of Common Stock issuable pursuant to a stock option agreement. UBS, therefore, is the beneficial owner of shares of Common Stock and capital stock convertible into, on an aggregate basis, approximately 19.4% of the issued and outstanding shares of Common Stock of the Company (based on 11,430,066 shares outstanding as of March 10, 2004 plus shares of Common Stock issuable upon the conversion and exercise of the reported securities). Pursuant to the terms of the Certificate of Incorporation of the Company, the conversion price of the Preferred Stock had initially been equal to the lesser of (i) 10% above the 20-day average bid price immediately prior to July 23, 1998 and (ii) 10% above the 20-day average bid price immediately prior to October 21, 1998, but in no event was the initial conversion price to be less than $8.50 per share. In accordance with the initial terms of the Preferred Stock in connection with the sale of the Series B Preferred Stock, the conversion price on the Preferred Stock was reduced from its initial conversion price of $8.50 per share to $8.14 per share. Pursuant to the terms of the Certificate of Incorporation, the conversion price of the Series B Preferred Stock is initially $6.50 per share. The Warrant has an exercise price of $1,000 for the purchase of Series C Preferred Stock and $6.50 for the purchase of Series D Preferred Stock and the Financing Warrant has an exercise price of $4.25 for the purchase of Series D Preferred Stock. Of the vested options, 25,000 options have an exercise price of $7.81 per share, 5,000 options have an exercise price of $10.75 per share, 5,000 options have an exercise price of $7.20 per share and 5,000 options have an exercise price of $9.31 per share. All of the vested Page 10 of 13 pages options are exercisable at any time. Prior to exercise, neither the warrants nor the options are accorded any voting rights. By virtue of the fact that UBS AG owns 100% of Holdings, which owns 100% of UBS Capital II LLC, UBS AG and Holdings are each the beneficial owner of all such stock. UBS AG and Holdings each disclaim beneficial ownership of any equity securities of the Company. b. By virtue of the Proxy granted to Buyer pursuant to the Voting Agreement, all as described in Item 4 above, the Buyer may be deemed to share the power to vote or direct the vote of the securities identified in paragraph (a) above with UBS in accordance with the terms of the Voting Agreement, to the extent such shares have the power to vote, under the circumstances described in the Certificates of Designation; subject to the restrictions contained in the Voting Agreement with respect to the transfer of the Company's securities, UBS has the sole power to dispose or direct the disposition of all shares identified in paragraph (a) above. The information required by Item 2 with respect to Buyer can be found in the Schedule 13D filed by Buyer. c. Except as described herein, the Reporting Persons have not effected any transaction in the securities of the Company during the past 60 days. d. Not applicable. e. Not applicable. ITEM 6 CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO THE COMMON STOCK OF THE ISSUER The word "herein" in the first sentence of the second paragraph of Item 6 is hereby deleted and replaced with the words "in the Schedule 13D, as amended". 7.
