Press Release

Allergan, Inc. to Acquire MAP Pharmaceuticals, Inc.

Acquisition Enhances Allergan Leadership Position in Neurology and Migraine Specialty

IRVINE, Calif. & MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Allergan, Inc. (NYSE:AGN) and MAP Pharmaceuticals, Inc. (Nasdaq: MAPP) today jointly announced that they have entered into a definitive merger agreement whereby Allergan will acquire 100% of the shares of MAP Pharmaceuticals for a price of $25.00 per share. MAP Pharmaceuticals is a biopharmaceutical company focused on developing and commercializing new therapies in Neurology, including LEVADEX®, an orally inhaled drug for the potential acute treatment of migraine in adults. LEVADEX® is currently under review with the U.S. Food and Drug Administration (FDA).

The transaction, which has been unanimously approved by the boards of directors of both companies, will be accomplished pursuant to a cash tender offer followed by a second step merger. The per share cash offer price represents a 60% premium over MAP’s closing stock price on the Nasdaq Stock Market of $15.58 on January 22, 2013, and represents a total equity value of approximately $958 million, on a fully-diluted basis. The acquisition is expected to close late in the first quarter or in the second quarter of 2013.

“One of the key drivers of Allergan’s continued success is our focus on medical specialties where we have extensive knowledge of physician and patient needs, and can provide a broad portfolio of products,” said David E.I. Pyott, Chairman of the Board, President and Chief Executive Officer, Allergan. “Allergan has a record of leadership in the Neurosciences field and, according to a recent physician survey, is now perceived as the #1 company in prophylactic migraine management by physicians. During the past few years, Allergan has received regulatory approvals in 56 countries for BOTOX® for use in the treatment of chronic migraine. As a result, thousands of patients who suffer from chronic migraine have benefited from this important treatment option. We plan to capitalize on this depth of expertise in Neurology as we continue the global development of LEVADEX® as a potential acute treatment for migraine that is complementary to BOTOX® and use MAP’s proprietary drug particle and inhalation technologies to generate new pipeline opportunities.”

“Through our dedicated employees at MAP Pharmaceuticals, we have made tremendous progress to date with our lead product candidate, LEVADEX®, enabling us to realize substantial value for our stockholders through this transaction,” said Timothy S. Nelson, President and Chief Executive Officer, MAP Pharmaceuticals. “We are pleased that we and Allergan share similar values and a common vision in neuroscience that make for a strong cultural and scientific fit between our companies. We believe this acquisition by our partner Allergan will increase the potential for our product candidates to make a meaningful difference for patients we have worked so hard to serve.”

In January 2011, Allergan entered into a collaboration agreement with MAP to co-promote LEVADEX®, contingent upon potential regulatory authority approvals in the U.S. and Canada, to neurologists and pain specialists in these markets. In May 2011, MAP initially submitted a New Drug Application (NDA) for LEVADEX® to the FDA. In October 2012, MAP resubmitted its NDA, which included additional data and provided responses to FDA comments. In November 2012, MAP announced that its NDA resubmission for LEVADEX® was accepted for filing by the FDA and that the FDA has classified the resubmission as a complete Class 2 response and has set a goal date of April 15th, 2013 under the Prescription Drug User Fee Act (PDUFA).

Assuming this transaction closes as planned, and approval of LEVADEX® occurs on or before the PDUFA date of April 15th, 2013, Allergan anticipates that this transaction will be dilutive to 2013 earnings per share by approximately $0.07 and accretive to earnings per share by the second half of 2014. Allergan will provide 2013 guidance on its February 5, 2013 earnings call. Allergan currently anticipates that, excluding this transaction, 2013 earnings per share growth expectations will fall within our mid-teens growth aspiration.

Allergan expects to fund the transaction with a combination of cash on hand, cash equivalents and short-term borrowings under its commercial paper program. The transaction is not subject to any financing contingency.

About the Cash Tender Offer

Under the terms of the definitive merger agreement, Allergan will commence a cash tender offer to purchase all of MAP’s outstanding shares for $25.00 per share, net to the seller in cash, without interest and less any applicable withholding taxes. The tender offer will remain open for at least 20 business days. The completion of the tender offer is subject to the tender of at least a majority of MAP’s outstanding shares of common stock (on a fully diluted basis), the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act, and other customary closing conditions. The merger agreement also provides for the parties to effect, subject to customary conditions, a merger following the completion of the tender offer which would result in all shares not tendered in the tender offer being converted into the right to receive $25.00 per share, net to the holder in cash, without interest and less any applicable withholding taxes. The board of directors of MAP has unanimously agreed to recommend that MAP’s stockholders tender their shares to Allergan in the tender offer. All of MAP’s directors and executive officers and a major stockholder of MAP affiliated with a director, collectively owning approximately 9 percent of MAP’s outstanding common stock, have entered into a tender and support agreement with Allergan committing to tender all of their MAP shares in the tender offer and, if applicable, to vote in favor of the merger.

In connection with this transaction, Goldman, Sachs & Co. is acting as financial advisor and Gibson, Dunn & Crutcher LLP as legal advisor to Allergan. Centerview Partners LLC is acting as exclusive financial advisor and provided a fairness opinion to MAP Pharmaceuticals, and Latham & Watkins LLP as legal advisor to MAP.

Allergan will host a 30-minute conference call on Wednesday, January 23, 2013, commencing at 8:00 a.m. Pacific Time (11:00 a.m. Eastern Time) to discuss and provide additional information regarding the proposed acquisition of MAP Pharmaceuticals.

AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants and premises contained in this Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties to this Agreement, intending to be legally bound, agree as follows:

ARTICLE 1

THE OFFER AND THE MERGER

1.1 The Offer.

(a) As promptly as practicable (and in any event within seven Business Days) after the date hereof, the Purchaser shall (and Parent shall cause Purchaser to) commence, within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”), the Offer to purchase all the outstanding Shares at the Offer Price, subject to: (i) there being validly tendered in the Offer and not properly withdrawn prior to the Expiration Date that number of Shares which, together with the number of Shares (if any) then owned of record by Parent or the Purchaser or with respect to which Parent or the Purchaser otherwise has, directly or indirectly, sole voting power, represents at least a majority of the Shares then outstanding (determined on a fully diluted basis assuming conversion or exercise of all derivative securities regardless of the conversion or exercise price, the vesting schedule or other terms and conditions thereof) (the “Minimum Condition”); and (ii) the satisfaction, or waiver by Parent or the Purchaser, of the other conditions set forth herein and in Annex I.

(b) Subject to the satisfaction of the Minimum Condition and the satisfaction, or waiver by Parent or the Purchaser, of the other conditions set forth herein and in Annex I, the Purchaser shall (and Parent shall cause the Purchaser to) accept for payment and pay for all Shares validly tendered and not properly withdrawn pursuant to the Offer as promptly as practicable after Purchaser is legally permitted to do so under applicable Law. The Offer Price payable in respect of each Share validly tendered and not properly withdrawn pursuant to the Offer shall be paid net to the seller in cash, without interest.

(c) The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) that describes the terms and conditions of the Offer in accordance with this Agreement, including the Minimum Condition and the other conditions set forth in Annex I. Parent and the Purchaser expressly reserve the right to increase the Offer Price or to make any other changes in the terms and conditions of the Offer; provided, however, that unless otherwise contemplated by this Agreement or as previously approved by the Company in writing, the Purchaser shall not (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) reduce the maximum number of Shares sought to be purchased in the Offer, (iv) amend or waive the Minimum Condition, (v) amend any of the other conditions to the Offer set forth in Annex I in a manner adverse to the holders of Shares or (vi) extend the Expiration Date in a manner other than in accordance with this Agreement.

(d) Unless extended in accordance with the terms of this Agreement, the Offer shall expire at midnight (New York City time) on the date that is 20 Business Days from and including the date of the commencement of the Offer (the “Initial Expiration Date”) or, if the Initial Expiration Date has been extended in accordance with this Agreement, the date on which the Offer has been so extended (the Initial Expiration Date, or such later date to which the Initial Expiration Date has been extended in accordance with this Agreement, the “Expiration Date”).

(e) If at the scheduled Expiration Date, all of the conditions to the Offer (including the Minimum Condition and the other conditions and requirements set forth herein and in Annex I) have not been satisfied, or waived by Parent or the Purchaser, and if this Agreement shall not have been terminated in accordance with Article 7, the Purchaser may (in its sole discretion, without consent of the Company) and, to the extent requested by the Company in writing prior to such scheduled Expiration Date, shall (and Parent shall cause the Purchaser

2

to) extend the Offer for successive periods of up to 20 Business Days each, the length of each such period to be determined by Parent in its sole discretion, in order to permit the satisfaction of such conditions; provided, however, that the Purchaser shall not be required to extend the Offer if any condition to the Offer has not been satisfied on or prior to May 22, 2013 (the “Outside Date”), beyond the Outside Date. In addition, if this Agreement shall not have been terminated in accordance with Article 7, the Purchaser shall extend the Offer for any period or periods required by applicable Law or applicable rules, regulations, interpretations or positions of the U.S. Securities and Exchange Commission (the “SEC”) or its staff.

(f) Notwithstanding the foregoing, if necessary to obtain sufficient Shares (including Shares issuable upon the exercise of the Top-Up Option) to reach the Short Form Threshold, the Purchaser may, in its sole discretion (and Parent may cause the Purchaser to), provide for a “subsequent offering period” (and one or more extensions thereof) in accordance with Rule 14d-11 under the Exchange Act of up to 10 Business Days, the length of the initial “subsequent offering period” and each extension thereof to be determined by the Purchaser in its sole discretion. Subject to the terms and conditions of this Agreement and the Offer, the Purchaser shall (and Parent shall cause the Purchaser to) immediately accept for payment, and pay for, all Shares that are validly tendered pursuant to the Offer during such “subsequent offering period”. The Offer Documents will provide for the possibility of a “subsequent offering period” in a manner consistent with the terms of this Section 1.1(f).

(g) The Purchaser shall not terminate the Offer prior to any scheduled Expiration Date without the prior written consent of the Company, except if this Agreement is terminated pursuant to Article 7. If this Agreement is terminated pursuant to Article 7, the Purchaser shall (and Parent shall cause the Purchaser to) promptly (and in any event within 24 hours of such termination), irrevocably and unconditionally terminate the Offer. If the Offer is terminated or withdrawn by the Purchaser, or this Agreement is terminated prior to the purchase of Shares in the Offer, the Purchaser shall promptly return, and shall cause any depositary acting on behalf of the Purchaser to return, in accordance with applicable Law, all tendered Shares to the registered holders thereof.

(h) As soon as practicable on the date of the commencement of the Offer, Parent and the Purchaser shall file with the SEC, in accordance with Rule 14d-3 under the Exchange Act, a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, supplements and exhibits thereto, the “Schedule TO”). The Schedule TO shall include, as exhibits, the Offer to Purchase, a form of letter of transmittal and a form of summary advertisement (collectively, together with any amendments and supplements thereto, the “Offer Documents”). Parent and the Purchaser agree to cause the Offer Documents to be disseminated to holders of Shares, as and to the extent required by the Exchange Act. The Company shall promptly provide Parent and the Purchaser in writing, for inclusion in the Offer Documents, all information concerning the Company that is required under the Exchange Act to be included in the Offer Documents. Parent and the Purchaser, on the one hand, and the Company, on the other hand, agree to promptly correct any information provided by it for use in the Offer Documents, if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by applicable Law, and Parent and the Purchaser agree to cause the Offer Documents, as so corrected, to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act. The Company and its counsel shall be given a reasonable opportunity to review the Schedule TO and the Offer Documents before they are filed with the SEC, and Parent and the Purchaser shall give due consideration to the reasonable additions, deletions or changes suggested thereto by the Company and its counsel. In addition, Parent and the Purchaser shall provide the Company and its counsel with copies of any written comments, and shall inform them of any oral comments, that Parent, the Purchaser or their counsel may receive from time to time from the SEC or its staff with respect to the Schedule TO or the Offer Documents promptly after receipt of such comments, and any written or oral responses thereto. The Company and its counsel shall be given a reasonable opportunity to review any such written responses, and Parent and the Purchaser shall give due consideration to the reasonable additions, deletions or changes suggested thereto by the Company and its counsel.

1.2 Company Actions.

The Company, on the one hand, and Parent and the Purchaser, on the other hand, agree to promptly correct any information provided by it for use in the Schedule 14D-9, if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by applicable Law, and the Company agrees to cause the Schedule 14D-9, as so corrected, to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act. Parent, the Purchaser and their counsel shall be given a reasonable opportunity to review and comment on the Schedule 14D-9 before it is filed with the SEC, and the Company shall include all additions, deletions or changes thereto suggested by Parent and its legal counsel that the Company reasonably determines to be appropriate. In addition, the Company shall provide Parent, the Purchaser and their counsel with copies of any written comments, and shall inform them of any oral comments, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments, and any written or oral responses thereto.

(b) The Company shall promptly furnish or cause to be furnished to the Purchaser mailing labels, security position listings, non-objecting beneficial owner lists and any other listings or computer files containing the names and addresses of the record or beneficial holders of the Shares as of the most recent practicable date, and shall promptly furnish Purchaser with such information (including, but not limited to, updated lists of holders of the Shares and their addresses, mailing labels, security position listings and non-objecting beneficial owner lists) and such other assistance and information as the Purchaser or its agents may reasonably request in communicating with the record and beneficial holders of Shares.

1.3 Directors.

(a) After the Purchaser accepts for payment Shares tendered and not properly withdrawn pursuant to the Offer (the “Acceptance Time”), and at all times thereafter, Parent shall be entitled to elect or designate such number of directors, rounded up to the next whole number, on the Company Board as is equal to the product of the total number of directors on the Company Board (giving effect to the directors elected or designated by Parent pursuant to this sentence) multiplied by the percentage that the aggregate number of Shares beneficially owned by Parent, the Purchaser or any of their respective Subsidiaries bears to the total number of Shares then outstanding. After the Acceptance Time, the Company shall, upon Parent’s request, take all actions as are necessary or desirable to enable Parent’s designees to be so elected or appointed to the Company Board, including but not limited to promptly filling vacancies or newly created directorships on the Company Board, promptly increasing the size of the Company Board (including by amending the Company Bylaws if necessary to increase the size of the Company Board) or promptly securing the resignations of such number of its incumbent directors, and shall cause Parent’s designees to be so elected or appointed at such time. After the Acceptance

4

Time, the Company shall also, upon Parent’s request, cause the directors elected or designated by Parent to the Company Board to serve on and constitute the same percentage (rounded up to the next whole number) as is on the Company Board of (i) each committee of the Company Board, (ii) each board of directors (or similar body) of each Company Subsidiary and (iii) each committee (or similar body) of each such board, in each case to the extent permitted by applicable Law and the Marketplace Rules of The NASDAQ Global Market (the “Nasdaq”). After the Acceptance Time, the Company shall also, upon Parent’s request, take all action necessary to elect to be treated as a “controlled company” as defined by Nasdaq Marketplace Rule 5615(c)(1) and make all necessary filings and disclosures associated with such status. The provisions of this Section 1.3(a) are in addition to and shall not limit any rights that Parent, the Purchaser or any of their respective affiliates may have as a record holder or beneficial owner of Shares as a matter of applicable Law with respect to the election of directors or otherwise.

(b) The Company’s obligations to appoint Parent’s designees to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The Company shall promptly take all actions required pursuant to Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 1.3(b), including mailing to stockholders (together with the Schedule 14D-9) any information required by Section 14(f) and Rule 14f-1 to enable Parent’s designees to be elected or designated to the Company Board at the time or times contemplated by this Section 1.3. Parent shall supply or cause to be supplied to the Company any information with respect to Parent, the Purchaser, their respective officers, directors and affiliates and proposed designees to the Company Board required by Section 14(f) and Rule 14f-1.

(c) After Parent’s designees are elected or appointed to, and constitute a majority of, the Company Board pursuant to Section 1.3(a), and prior to the Effective Time, the Company shall cause the Company Board to maintain at least three directors who are members of the Company Board on the date hereof, each of whom shall be an “independent director” as defined by Rule 5605(a)(2) of the Nasdaq Marketplace Rules and eligible to serve on the Company’s audit committee under the Exchange Act and Nasdaq rules and, at least one of whom shall be an “audit committee financial expert” as defined in Item 407(d)(5) of Regulation S-K and the instructions thereto (the “Continuing Directors”); provided, however, that if any Continuing Director is unable to serve due to death, disability or resignation, the Company shall take all necessary action (including creating a committee of the Company Board) so that the remaining Continuing Director or Continuing Directors shall be entitled to elect or designate another Person that satisfies the foregoing independence requirements to fill such vacancy, and such Person shall be deemed to be a Continuing Director for purposes of this Agreement. After Parent’s designees are elected or designated to, and constitute a majority of, the Company Board pursuant to Section 1.3(a), and prior to the Effective Time, in addition to any approvals of the Company Board or the stockholders of the Company as may be required by the Company Certificate, the Company Bylaws or applicable Law, subject to the terms hereof, the affirmative vote of a majority of the Continuing Directors shall be required (i) for the Company to terminate this Agreement or amend this Agreement, (ii) for the Company to exercise or waive any of the Company’s rights, benefits or remedies under this Agreement, (iii) except as otherwise contemplated by this Agreement, to amend the Company Certificate or the Company Bylaws or (iv) to take any other action of the Company Board under or in connection with this Agreement, in each case, if such termination, amendment, exercise, waiver or other action would reasonably be expected to adversely affect in any material respect the holders of Shares (other than Parent or the Purchaser); provided, however, that if there shall be no Continuing Directors as a result of such Persons’ deaths, disabilities or resignations, then such actions may be effected by majority vote of the entire Company Board.

1.6 Meeting of Stockholders to Approve the Merger.

(a) If required by applicable Law in order to consummate the Merger, the Company shall prepare a proxy statement or information statement for the Special Meeting (together with any amendments and supplements thereto and any other required proxy materials, the “Proxy Statement”) relating to the Merger and this Agreement, with the intention that the Proxy Statement be in a form ready, if necessary, to file with the SEC, print and mail to the stockholders of the Company as soon as practicable following the Acceptance Time. Parent, the Purchaser and their counsel shall be given a reasonable opportunity to review the Proxy Statement before it is filed with the SEC, and the Company shall give due consideration to the reasonable additions, deletions or changes suggested thereto by Parent, the Purchaser and their counsel. The Company shall include the Company Board Recommendation and the Fairness Opinion, together with a summary thereof in accordance with Item 1015(b) of Regulation M-A under the Exchange Act (regardless of whether such item is applicable), in the Proxy Statement. The Company, on the one hand, and Parent and the Purchaser, on the other hand, agree to promptly correct any information provided by it for use in the Proxy Statement, if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by applicable Law, and the Company agrees to cause the Proxy Statement, as so corrected, to be filed with the SEC and, if any such correction is made following the mailing of the Proxy Statement, mailed to holders of Shares, in each case as and to the extent required by the Exchange Act. The Company shall provide Parent, the Purchaser and their counsel with copies of any written comments, and shall inform them of any oral comments, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Proxy Statement promptly after the Company’s receipt of such comments, and any written or oral responses thereto. Parent, the Purchaser and their counsel shall be given the reasonable opportunity to review any such written responses and the Company shall give due consideration to the reasonable additions, deletions or changes suggested thereto by Parent, the Purchaser and their counsel.

(b) If approval of the stockholders of the Company is required under applicable Law to consummate the Merger, the Company, acting through the Company Board, shall, in accordance with and subject to the requirements of applicable Law: (i) as promptly as practicable after the Acceptance Time, in consultation with Parent, duly set a record date for, call and give notice of a special meeting of its stockholders (the “Special Meeting”) for the purpose of considering and taking action upon this Agreement (with the record date to be set in consultation with Parent for a date after the Acceptance Time); (ii) promptly after the Acceptance Time, file the Proxy Statement with the SEC, cause the Proxy Statement to be printed and mailed to the stockholders of the Company and convene and hold the Special Meeting; and (iii) use commercially reasonable efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and approval of the transactions contemplated hereby, including the Merger, and secure any approval of stockholders of the Company that is required by applicable Law to effect the Merger.

(c) At the Special Meeting or any postponement or adjournment thereof, Parent shall vote, or cause to be voted, all of the Shares then owned of record by Parent or the Purchaser or with respect to which Parent or the Purchaser otherwise has, directly or indirectly, sole voting power in favor of the adoption of this Agreement and approval of the transactions contemplated hereby, including the Merger, and to deliver or provide, in its capacity as a stockholder of the Company, any other approvals that are required by applicable Law to effect the Merger.

1.7 Merger Without Meeting of Stockholders. Notwithstanding the terms of Section 1.6, if after the Acceptance Time and, if applicable, the expiration of any “subsequent offering period” provided by the Purchaser in accordance with this Agreement and the exercise of the Top-Up Option, Parent and the Purchaser shall then own, in the aggregate, at least 90% of the outstanding shares of each class of capital stock of the Company entitled to vote on the adoption of this Agreement under applicable Law (the “Short Form Threshold”), the parties hereto agree to take all necessary and appropriate action to cause the Merger to become effective as promptly as practicable without a meeting of stockholders of the Company in accordance with Section 253 of the DGCL.

1.8 Top-Up Option.

(a) The Company hereby irrevocably grants to the Purchaser an option (the “Top-Up Option”), exercisable only upon the terms and subject to the conditions set forth in this Section 1.8, to purchase at a price per share equal to the Offer Price an aggregate number of Shares (the “Top-Up Option Shares”) equal to the lowest number of Shares that, when added to the number of Shares owned by Parent and the Purchaser at the time of such exercise, shall constitute one share more than 90% of the Shares then outstanding (after giving effect to the issuance of the Top-Up Option Shares); provided, however, that the Top-Up Option shall not be exercisable unless, (i) the Minimum Condition shall have been satisfied and (ii) immediately after such exercise and the issuance of Shares pursuant thereto, the Purchaser reasonably believes that the Short Form Threshold would be reached (assuming the issuance of the Top-Up Option Shares); provided, further, that in no event shall the Top-Up Option be exercisable for a number of Shares in excess of the Company’s then total authorized and unissued Shares, excluding any Shares that are reserved or otherwise committed for issuance. Upon Parent’s request, the Company shall use commercially reasonable efforts to cause its transfer agent to certify in writing to Parent the number of Shares issued and outstanding as of immediately prior to the exercise of the Top-Up Option and after giving effect to the issuance of the Top-Up Option Shares. The Purchaser shall pay the Company the aggregate price required to be paid for the Top-Up Option Shares in cash for the amount equal to the aggregate par value of the Top-Up Option Shares, with the balance payable by delivery of a non- negotiable and non-transferable promissory note (the “Promissory Note”). The Promissory Note shall be secured by the Top-Up Option Shares, be full recourse against Parent and the Purchaser, be due one year from the date the Top-Up Option Shares are issued and bear interest at the rate of 5% per annum and may be prepaid without premium or penalty.

(b) Provided that no applicable Law shall prohibit the exercise of the Top-Up Option or the issuance of the Top-Up Option Shares pursuant thereto, or otherwise make such exercise or issuance illegal, the Purchaser may exercise the Top-Up Option on one or more occasions, in whole or in part, after the Acceptance Time and prior to the earlier to occur of (i) the Effective Time and (ii) the termination of this Agreement in accordance with its terms.

(c) Each time that the Purchaser wishes to exercise the Top-Up Option, the Purchaser shall send to the Company a written notice (a “Top-Up Exercise Notice”) specifying the denominations of the certificate or certificates evidencing the Top-Up Option Shares that the Purchaser wishes to receive, and the place, time and date for the closing of the purchase and sale pursuant to the Top-Up Option (the “Top-Up Closing”). The Company shall, promptly after receipt of the Top-Up Exercise Notice, deliver a written notice to the Purchaser confirming the number of Top-Up Option Shares and the aggregate purchase price therefor (the “Top-Up Notice Receipt”). At the Top-Up Closing, the Purchaser shall deliver to the Company the consideration required to be delivered in exchange for the Top-Up Option Shares in an aggregate amount equal to the purchase price specified in the Top-Up Notice Receipt, and the Company shall cause to be issued and delivered to the Purchaser a certificate or certificates representing the Top-Up Option Shares. Such certificates may include any legends that are required by applicable Law. Parent and the Purchaser acknowledge that the Top-Up Option Shares which Parent or the Purchaser may acquire upon exercise of the Top-Up Option shall not be registered under the Securities Act, and shall be issued in reliance upon an exemption for transactions not involving a public offering. Parent and the Purchaser agree that the Top-Up Option, and the Top-Up Option Shares to be acquired upon exercise of the Top-Up Option, if any, are being and shall be acquired by the Purchaser for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof (within the meaning of the Securities Act).

ARTICLE 2

CONVERSION OF SECURITIES IN THE MERGER

2.1 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, the Purchaser, the Company or the holders of any of the following securities:

(a) Conversion of Company Common Stock. Each Share issued and outstanding immediately prior to the Effective Time, other than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares, shall be converted into the right to receive the Offer Price (the “Merger Consideration”), payable net to the holder in cash, without interest, upon surrender of the certificate formerly representing such Shares in accordance with Section 2.2.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are held in the treasury of the Company or owned of record by any Company Subsidiary, and all Shares owned of record by Parent, the Purchaser or any of their respective wholly-owned Subsidiaries shall be cancelled and shall cease to exist, with no payment being made with respect thereto.

(c) Purchaser Common Stock. Each share of common stock, par value $0.001 per share, of the Purchaser (the “Purchaser Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into and become one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

2.2 Payment for Securities; Surrender of Certificates.

(a) Paying Agent. At or prior to the Effective Time, Parent shall designate a reputable bank or trust company to act as the paying agent for purposes of effecting the payment of the Merger Consideration in connection with the Merger (the “Paying Agent”). At or promptly after the Effective Time, Parent or the Purchaser shall deposit, or cause to be deposited, with the Paying Agent the aggregate Merger Consideration to which holders of Shares shall be entitled at the Effective Time pursuant to this Agreement, together with the aggregate Option Payments, and RSU Payments. Such funds shall be invested by the Paying Agent as directed by Parent, in its sole discretion, pending payment thereof by the Paying Agent to the holders of the Shares. Earnings from such investments shall be the sole and exclusive property of Parent, and no part of such earnings shall accrue to the benefit of holders of Shares.

(b) Procedures for Surrender. As promptly as practicable after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of a certificate or certificates that represented Shares (the “Certificates”) or non-certificated Shares represented by book-entry (“Book-Entry Shares”), in each case, which Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement: (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent, and shall otherwise be in such form and have such other provisions as Parent or the Paying Agent may reasonably specify, and (ii) instructions for effecting the surrender of the Certificates or Book-Entry Shares in exchange for payment of the Merger Consideration. Upon surrender of Certificates and Book-Entry Shares for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, and upon delivery of a letter of transmittal, duly executed and in proper form, with respect to such Certificates or Book-Entry Shares, the holder of such Certificates or Book-Entry Shares shall be entitled to receive the Merger Consideration for each Share formerly represented by such Certificates and for each Book-Entry Share. Any Certificates and Book-Entry Shares so surrendered shall forthwith be cancelled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name any surrendered Certificate is registered, it shall be a condition precedent of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer, and the Person requesting such payment shall have paid any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate

9

so surrendered and shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not required to be paid. Payment of the Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered. Until surrendered as contemplated hereby, each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration in cash as contemplated by this Agreement, without interest thereon.

(c) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of Certificates and Book-Entry Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Agreement.

(d) Termination of Fund; Abandoned Property; No Liability. At any time following the first anniversary of the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed to holders of Certificates or Book-Entry Shares, and thereafter such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates or Book-Entry Shares and compliance with the procedures in Section 2.2(b), without interest. If, prior to six years after the Effective Time (or otherwise immediately prior to such time on which any payment in respect hereof would escheat to or become the property of any Governmental Entity pursuant to any applicable abandoned property, escheat or similar Laws), any holder of Certificates or Book-Entry Shares has not complied with the procedures in Section 2.2(b) to receive payment of the Merger Consideration to which such holder would otherwise be entitled, the payment in respect of such Certificates or Book-Entry Shares shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto. Notwithstanding the foregoing, none of Parent, the Surviving Corporation or the Paying Agent shall be liable to any holder of a Certificate or Book-Entry Shares for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(e) Withholding Rights. Parent, the Purchaser, the Surviving Corporation and the Paying Agent, as the case may be, shall be entitled to deduct and withhold from the relevant Offer Price, Merger Consideration, Option Payment, and RSU Payment otherwise payable pursuant to this Agreement to any holder of Shares, Company Options, or Company RSUs, as applicable, such amounts that Parent, the Purchaser, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or non-United States Tax Law or under the terms of any Company Benefit Plan. To the extent that amounts are so withheld and remitted to the appropriate Governmental Entity, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares, Company Options, or Company RSUs, as applicable, in respect of which such deduction and withholding was made.

(f) Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to Section 2.1(a) hereof; provided, however, that Parent may, in its discretion and as a condition precedent to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Purchaser, the Surviving Corporation or the Paying Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

10

2.3 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who is entitled to demand and has properly demanded appraisal for such Shares in accordance with, and who complies in all respects with, Section 262 of the DGCL (such Shares, the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration, and shall instead represent the right to receive payment of the fair value of such Dissenting Shares in accordance with and to the extent provided by Section 262 of the DGCL. If any such holder fails to perfect or otherwise waives, withdraws or loses his right to appraisal under Section 262 of the DGCL or other applicable Law, then the right of such holder to be paid the fair value of such Dissenting Shares shall cease and such Dissenting Shares shall be deemed to have been converted, as of the Effective Time, into and shall be exchangeable solely for the right to receive the Merger Consideration, without interest. The Company shall give Parent prompt notice of any demands received by the Company for appraisal of Shares, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to rights to be paid the fair value of Dissenting Shares, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, except with the prior written consent of Parent, make any payment with respect to, or settle or compromise or offer to settle or compromise, any such demands, or approve any withdrawal of any such demands, or agree to do any of the foregoing. The parties hereby agree and acknowledge that in any appraisal proceeding with respect to the Dissenting Shares and to the fullest extent permitted by applicable Law in any appraisal proceeding under Section 262 of the DGCL with respect to Dissenting Shares, the Surviving Company shall not assert that the exercise of the Top-Up Option, any issuance of the Top-Up Option Shares or any delivery by the Purchaser of the Promissory Note to the Company in payment for the Top-Up Option Shares should be considered in connection with a determination of the fair value of the Dissenting Shares in accordance with Section 262(h) of the DGCL.

2.4 Treatment of Company Options; Restricted Stock; Company RSUs; Stock Plans.

(a) Treatment of Company Options. Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof) shall adopt appropriate resolutions and take all other actions necessary and appropriate (including amendment of any equity plan or award agreement evidencing the grant of a Company Option, accelerating the vesting of any Company Option, and providing advance notice and an opportunity to exercise any Company Option) to provide that, immediately prior to the Effective Time, each unexpired and unexercised option to purchase Shares (the “Company Options”), under any stock option plan of the Company, including the 2004 Long-Term Incentive Plan, 2005 Equity Incentive Plan or the 2007 Equity Award Plan, or any other plan, agreement or arrangement (the “Company Stock Option Plans”), whether or not then exercisable or vested, shall be cancelled and, in exchange therefor, each former holder of any such cancelled Company Option shall, subject to its delivery to the Company of a duly executed option termination agreement with respect to Company Options granted under the 2004 Long-Term Incentive Plan, be entitled to receive, in consideration of the cancellation of such Company Option and in full settlement therefor, a payment in cash (subject to any applicable withholding or other Taxes or other amounts required by applicable Law to be withheld in accordance with Section 2.2(e)) of an amount equal to the product of (i) the total number of Shares previously subject to such Company Option and (ii) the excess, if any, of the Merger Consideration over the exercise price per Share previously subject to such Company Option; provided, that if the exercise price per share under any such Company Option is equal to or greater than the Merger Consideration, then such Company Stock Option shall be cancelled without any cash payment being made in respect thereof (such amounts payable hereunder being referred to as the “Option Payments”). From and after the Effective Time, any such cancelled Company Option shall no longer be exercisable by the former holder thereof, but shall only entitle such holder to the payment of the Option Payment.

(b) Treatment of Restricted Stock. Prior to the Effective Time, in accordance with the terms of the Company Stock Option Plans, each unvested Share subject to forfeiture restrictions, repurchase rights or other restrictions under the Company Stock Option Plans (“Restricted Stock”) shall vest in full and all restrictions (including forfeiture restrictions or repurchase rights) otherwise applicable to such Restricted Stock shall lapse

11

and the Restricted Stock shall be converted into the right to receive the Merger Consideration, without interest, as provided in Section 2.1(a), subject to any withholding of Taxes or other amounts required to be withheld by applicable Law in accordance with Section 2.2(e).

(c) Treatment of Company RSUs. Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof) shall adopt appropriate resolutions and take all other actions necessary and appropriate under the Company Stock Option Plans to provide that, immediately prior to the Effective Time, each outstanding restricted stock unit awarded pursuant to any Company Stock Option Plan (the “Company RSUs”), whether or not then vested, shall be cancelled and, in exchange therefor, each former holder of any such cancelled Company RSU shall be entitled to receive, in consideration of the cancellation of such Company RSU and in full settlement therefor, a payment in cash (subject to any applicable withholding or other Taxes required by applicable Law to be withheld in accordance with Section 2.2(e)) of an amount equal to the product of (i) the total number of Shares previously subject to such Company RSU and (ii) the Merger Consideration (such amounts payable hereunder being referred to as the “RSU Payments”). The holders of all canceled Company RSUs shall, as of the Effective Time, cease to have any further right or entitlement to acquire Shares under their canceled Company RSUs.

(d) Termination of Company Stock Option Plans. After the Effective Time, all Company Stock Option Plans shall be terminated and no further Company Options or other rights with respect to Shares shall be granted thereunder.

2.5 Treatment of Employee Stock Purchase Plan. The current offerings in progress as of the date hereof under the Company’s Employee Stock Purchase Plan (the “ESPP”) shall continue, and the shares of Company Common Stock shall be issued to participants thereunder on the next currently scheduled purchase dates thereunder occurring after the date hereof as provided under, and subject to the terms and conditions of, the ESPP. In accordance with the terms of the ESPP, any offering in progress as of the Effective Time shall be shortened, and the “Exercise Date” (as defined in the ESPP) shall be the business day immediately preceding the Effective Time. Each then outstanding option under the ESPP shall be exercised automatically on such Exercise Date. Notwithstanding any restrictions on transfer of stock in the ESPP, the treatment in the Merger of any stock under this provision shall be in accordance with Section 2.1(a). The Company shall terminate the ESPP as of or prior to the Effective Time. The Company shall promptly after the date hereof amend the ESPP as appropriate to avoid the commencement of any new offering of options thereunder at or after the date hereof and prior to the earlier of the termination of this Agreement or the Effective Time.

24

Property or the Material Intellectual Property owned by the Company, and to maintain the effectiveness of the Company Registered Intellectual Property and Material Intellectual Property owned by the Company.

Each of Parent and the Purchaser is duly qualified to do business in each jurisdiction where the ownership, leasing or operation of its properties or assets or the conduct of its business requires such qualification, except where the failure to be so qualified or in good standing, individually or in the aggregate, would not reasonably be expected to have a Parent Material Adverse Effect.

The Company shall immediately cease and cause to be terminated any and all existing activities, discussions or negotiations with any Persons conducted on or prior to the date of this Agreement with respect to any Acquisition Proposal, and shall promptly after the date of this Agreement instruct each Person that has in the twelve months prior to the date of this Agreement executed a confidentiality agreement relating to an Acquisition Proposal with or for the benefit of the Company to promptly return or destroy in accordance with the terms of such confidentiality agreement all information, documents and materials relating to the Acquisition Proposal or to the Company or any Company Subsidiary and their respective businesses previously furnished by or on behalf of the Company or any Company Subsidiary or any Company Representatives.

(b) From the date of this Agreement until the earlier of the Acceptance Time or the termination of this Agreement in accordance with its terms, the Company shall promptly (and in any event within three Business Days) provide Parent with: (i) an oral and a written description of any inquiry, expression of interest, proposal or offer relating to an Acquisition Proposal (including any modification thereto), or any request for information that would reasonably be expected to lead to an Acquisition Proposal, that is received by the Company or any Company Subsidiary or any Representative of the Company or any Company Subsidiary from any Person (other than Parent or the Purchaser) including in such description the identity of the Person from which such inquiry, expression of interest, proposal, offer or request for information was received (the “Other Interested Party”); and (ii) a copy of each material written communication and a summary of each material oral communication transmitted on behalf of the Other Interested Party or any of its Representatives to the Company or any Company Subsidiary or any of their Representatives or transmitted on behalf of the Company or any Company Subsidiary or any Representative of the Company or any Company Subsidiary to the Other Interested Party or any of its Representatives. Without limiting the foregoing, the Company shall promptly (and in any event within three Business Days) notify Parent orally and in writing if the Company determines to begin providing information or to engage in discussions or negotiations concerning an Acquisition Proposal pursuant to Section 5.3(c).

(c) Notwithstanding anything to the contrary contained in Section 5.3(a), if at any time following the date hereof and prior to the Acceptance Time (i) the Company has received a bona fide written Acquisition Proposal from a third party, (ii) the Company Board determines in good faith, after consultation with its financial advisors and outside counsel, that such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (iii) after consultation with its outside counsel, the Company Board determines in good faith that the failure to take such actions would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, then the Company may take the following actions: (A) furnish information with respect to the Company and any Company Subsidiary to the Person making such Acquisition Proposal and (B) participate in discussions or negotiations with the Person making such Acquisition Proposal regarding such Acquisition Proposal; provided that the Company (x) shall not, and shall not allow any Company Subsidiary or any Company Representative to, disclose any information to such Person without first entering into an Acceptable Confidentiality Agreement, and (y) shall promptly provide to Parent any information concerning the Company or any Company Subsidiary provided to such other Person which was not previously provided to Parent.

36

Acquisition Proposal, (iii) submit any Acquisition Proposal or any matter related thereto to the vote of the stockholders of the Company or (iv) resolve or agree to take any such actions (each such action set forth in this Section 5.3(d) being referred to as a “Change of Board Recommendation”).

(e) Notwithstanding anything to the contrary contained herein, the Company Board may, at any time prior to the Acceptance Time, make a Change of Board Recommendation for a reason unrelated to an Acquisition Proposal (it being understood and agreed that any Change of Board Recommendation proposed to be made in relation to an Acquisition Proposal may only be made pursuant to and in accordance with the terms of Section 5.3(f)) if the Company Board has determined in good faith, after consultation with its outside legal counsel, that, in light of facts, events and/or circumstances that have developed since the Agreement Date and prior to the Acceptance Time and of which the Company Board did not, as of the date hereof, have knowledge and that were not reasonably foreseeable by the Company Board as of or immediately prior to the date hereof after due inquiry of the Company’s executive management team (an “Intervening Event”) and taking into account the results of any negotiations with Parent as contemplated by subsection ii. below and any offer from Parent contemplated by subsection iii below, the failure to take such action would reasonably be expected to be inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law (it being agreed that, for the avoidance of doubt, the approval by the FDA of NDA Number 202-363 (or any resubmission of such NDA or any other NDA relating to the Levadex Product) shall be deemed not to constitute an Intervening Event); provided, however, that the Company Board may not withdraw, modify or amend the Company Board Recommendation in a manner adverse to Parent pursuant to the foregoing unless:

i. the Company shall have provided prior written notice to Parent, at least three Business Days in advance (the “Intervening Event Notice Period”) of the Company’s intention to make a Change of Board Recommendation (it being understood that the delivery of such notice and any amendment or update thereto and the determination to so deliver such notice, update or amendment shall not, by itself, constitute a Change of Board Recommendation or otherwise give rise to a Triggering Event), which notice shall specify the Company Board reason for proposing to effect such Change of Board Recommendation pursuant to this Section 5.3(e);

ii. prior to effecting such Change of Board Recommendation, the Company shall, and shall cause the Company Representatives to, during the Intervening Event Notice Period negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement in such a manner that would obviate the need for the Company Board to effect such Change of Board Recommendation; and

iii. Parent shall not have, within the aforementioned three Business Day period, made a written, binding and irrevocable (through the expiration of such period) offer to modify the terms and conditions of this Agreement, which is set forth in a definitive written amendment to this Agreement delivered to the Company and executed on behalf of Parent and the Purchaser, that the Company Board has in good faith determined (after consultation with its outside legal counsel and its financial advisor) would obviate the need for the Company Board to effect such Change of Board Recommendation.

(f) Notwithstanding anything to the contrary contained in this Article 5, if the Company receives an Acquisition Proposal that the Company Board determines in good faith, after consultation with outside counsel and its financial advisors, constitutes a Superior Proposal, after giving effect to all of the adjustments to the terms and conditions of this Agreement that have been delivered to the Company by Parent in writing during the Notice Period provided pursuant to this Section 5.3(f), that are binding and have been irrevocably committed to by Parent in writing, and provided that such Acquisition Proposal did not result from or arise in connection with a material breach by the Company or any of its Representatives of this Section 5.3, the Company Board may at any time prior to the Acceptance Time, if the Company Board determines in good faith, after consultation with outside counsel, that the failure to take such actions would be inconsistent with the fiduciary duties owed by the Company Board to the stockholders of the Company under applicable Law, take the following action: (y) effect a Change of Board Recommendation with respect to such Superior Proposal or (z) terminate this Agreement to

37

enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing clause (z), and any purported termination pursuant to the foregoing clause (z) shall be void and of no force or effect, unless in advance of or concurrently with such termination the Company pays the Breakup Fee and otherwise complies with the provisions of Sections 7.1(f) and 7.2; and provided further that the Company Board may not withdraw, modify or amend the Company Board Recommendation in a manner adverse to Parent pursuant to the foregoing clause (y) or terminate this Agreement pursuant to the foregoing clause (z) unless:

i. the Company shall have provided prior written notice to Parent, at least three Business Days in advance (the “Notice Period”), of the Company’s intention to take such action with respect to such Superior Proposal (it being understood that the delivery of such notice and any amendment or update thereto and the determination to so deliver such notice, update or amendment shall not, by itself, constitute a Change of Board Recommendation or otherwise give rise to a Triggering Event), which notice shall specify the material terms and conditions of such Superior Proposal, (including the identity of the party making such Superior Proposal) and shall have contemporaneously provided a copy of the relevant proposed transaction agreements with the party making such Superior Proposal, including the definitive agreement with respect to such Superior Proposal; and

ii. prior to effecting such Change of Board Recommendation or terminating this Agreement to enter into a definitive agreement with respect to such Superior Proposal, the Company shall, and shall cause the Company Representatives to, during the Notice Period, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal. In the event of any material revisions to the Superior Proposal, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 5.3(e) with respect to such new written notice (provided that the Notice Period for any subsequent notice shall be shortened from three Business Days to one Business Day). The Company agrees that any violation of the restrictions set forth in this Section 5.3 by any of the Company Representatives shall be deemed to be a material breach of this Agreement (including this Section 5.3) by the Company.

(g) Nothing contained in this Section 5.3 shall prohibit the Company Board from (i) disclosing to the stockholders of the Company a position contemplated by Rule 14e-2(a) or complying with the provisions of Rule 14d-9 promulgated under the Exchange Act or (ii) making any disclosure to the stockholders of the Company that the Company Board determines to make in good faith (after consultation with its outside legal counsel) in order to fulfill its fiduciary duties under, or in order to otherwise comply with, Applicable Law; provided, however, that the content of any such disclosure shall be governed by the terms of this Agreement; and provided, further, that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed to be a Change of Board Recommendation unless the Company Board expressly reaffirms its recommendation to its stockholders in favor of the Offer and Merger in such disclosure.

(h) The Company agrees that any violation of the restrictions set forth in this Section 5.3 by any Company Representative, whether or not such Person is purporting to act on behalf of the Company or any Company Subsidiary or otherwise, shall be deemed to be a breach of this Agreement by the Company.

(i) The Company shall not, and shall cause the Company Subsidiaries not to, enter into any confidentiality agreement with any Person subsequent to the date of this Agreement that would restrict the Company’s ability to comply with any of the terms of this Section 5.3, and represents that neither it nor any of its Subsidiaries is a party to any such agreement.

5.4 Appropriate Action; Consents; Filings.

(a) The Company and Parent shall use their commercially reasonable efforts to (i) take, or cause to be taken, all appropriate action and do, or cause to be done, all things necessary, proper or advisable under

38

applicable Law or otherwise to consummate and make effective the transactions contemplated by this Agreement as promptly as practicable, (ii) obtain from any Governmental Entities any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained by Parent or the Company or any of their respective Subsidiaries, or to avoid any action or proceeding by any Governmental Entity (including those in connection with the HSR Act), in connection with the authorization, execution and delivery of this Agreement and the consummation of the transactions contemplated herein, including the Offer and the Merger and (iii) as promptly as reasonably practicable, and in any event within 10 Business Days after the date hereof, make all necessary filings, and thereafter make any other required submissions, and pay any fees due in connection therewith, with respect to this Agreement, the Offer and the Merger required under (A) the Exchange Act, and any other applicable federal or state securities Laws, (B) the HSR Act and (C) any other applicable Law; provided, that the Company and Parent shall cooperate with each other in connection with (x) preparing and filing the Offer Documents, the Schedule 14D-9, the Proxy Statement and any Other Filings, (y) determining whether any action by or in respect of, or filing with, any Governmental Entity is required, in connection with the consummation of the Offer or the Merger and (z) seeking any such actions, consents, approvals or waivers or making any such filings.

Each party hereto will consult and cooperate with the other parties and will consider in good faith the views of the other parties in connection with any filing, analysis, appearance, presentation, memorandum, brief, argument, opinion or proposal made or submitted in connection with the Offer, the Merger or any of the other transactions contemplated by this Agreement. In addition, except as may be prohibited by any Governmental Entity or by any Law, in connection with any such request, inquiry, investigation, action or legal proceeding, each party hereto will permit authorized representatives of the other parties to be present at each meeting or conference relating to such request, inquiry, investigation, action or legal proceeding and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Entity in connection with such request, inquiry, investigation, action or legal proceeding.

(d) Each of Parent, the Purchaser and the Company shall (i) cooperate and coordinate with the other in the making of any filings or submissions that are required to be made under any applicable Competition Laws or requested to be made by any Governmental Entity in connection with the transactions contemplated by this Agreement, (ii) supply the other or its outside counsel with any information that may be required or requested by any Governmental Entity in connection with such filings or submissions, (iii) supply any additional information that may be required or requested by the Federal Trade Commission, the Department of Justice or other Governmental Entities in which any such filings or submissions are made under any applicable Competition Laws as promptly as practicable, (iv) use their commercially reasonable efforts to cause the expiration or

In furtherance and not in limitation of the covenants of the parties contained in this Section 5.4, if any objections are asserted with respect to the transactions contemplated hereby under any Competition Law or if any suit is instituted (or threatened to be instituted) by the Federal Trade Commission, the Department of Justice or other Governmental Entities or any private party challenging any of the transactions contemplated hereby as violative of any Competition Law or that would otherwise prevent materially impede or materially delay the consummation of the transactions contemplated hereby, each of Parent, the Purchaser and the Company shall use its commercially reasonable efforts to resolve any such objections or suits so as to permit consummation of the transactions contemplated by this Agreement, including (i) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any non-material assets or business of the Company or its Subsidiaries taken as a whole and (ii) otherwise taking or committing to take any actions that after the Closing would not materially limit the freedom of action of Parent or its Subsidiaries (including the Surviving Corporation) with respect to, or its ability to retain, one or more of its or its Subsidiaries’ (including the Surviving Corporation’s) businesses, material product lines or assets, in each case as may be required in order to resolve such objections or suits by the Expiration Date; provided, however, that neither the Company nor any of its Subsidiaries nor Parent nor any of its Subsidiaries or affiliates shall be obligated to, and the Company shall not without Parent’s prior written consent, become subject to, or consent or agree to or otherwise take any action with respect to, any requirement, condition, understanding, agreement or order of a Governmental Entity to sell, hold separate, dispose of any assets or conduct or change its business unless such requirement, condition, understanding, agreement or order is binding on the Company or any of its Subsidiaries or on Parent or any of its Subsidiaries or affiliates, as the case may be, only in the event the Closing occurs.

(e) Subject to the obligations under Section 5.4(d), (i) if any Governmental Entity issues an order, decree, injunction or ruling or takes any other action enjoining or otherwise preventing the consummation of the Offer or the Merger, or (ii) if any other administrative or judicial action or proceeding is instituted (or threatened to be instituted) by a Governmental Entity or private party that challenges, or seeks to prohibit, prevent or restrict the consummation of the Offer, the Merger or any other transaction contemplated by this Agreement, or any other agreement contemplated hereby, then (x) at their sole cost and expense, Parent and the Purchaser shall (1) use commercially reasonable efforts to have vacated, lifted, reversed or overturned any such order, decree, injunction or ruling and (2) defend, contest and resist any such action or proceeding, and (y) each of Parent, the Purchaser and the Company shall cooperate in a commercially reasonable manner with each other in connection therewith.

(f) Notwithstanding anything to the contrary in this Agreement, nothing contained in this Agreement shall give Parent or the Purchaser, directly or indirectly, the right to control or direct the operations of the Company prior to the consummation of the Offer. Prior to the consummation of the Offer, the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations.

5.5 Certain Notices.

(a) From and after the date of this Agreement until the Effective Time, each party hereto shall promptly notify the other party hereto of (i) the occurrence, or non-occurrence, of any event that would be likely to cause any condition to the obligations of any party to effect the Offer, the Merger or any other transaction contemplated by this Agreement not to be satisfied or (ii) the failure of the Company or Parent, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any party to effect the Offer, the Merger or any other transaction contemplated by this Agreement not to be satisfied; provided, however, that the delivery of any notice pursuant to this Section 5.5 shall not cure any breach of any representation, warranty, covenant or agreement contained in this Agreement or otherwise limit or affect the remedies available hereunder to the party receiving such notice.

40

(b) From and after the date of this Agreement until the Effective Time, the Company agrees to provide Parent with: (i) advance written notice of the Company’s intent to submit a major amendment to or resubmission of (as those terms are used in 21 C.F.R. 314.60) NDA Number 202-363 (a “Major Amendment”) at least 20 Business Days prior to the date that the Company submits such Major Amendment to the extent such Major Amendment is reasonably expected to delay the timeline for FDA review of the NDA in accordance with 21 C.F.R. 314.60; (ii) a copy of such Major Amendment at least five Business Days prior to submission to the FDA; (iii) except as may be prohibited by any Governmental Entity or by any Law, any communications with the FDA with respect to the Levadex Product that may reasonably be deemed to impact or potentially impact, in any material respect, the Levadex Product or the FDA Approval, including any communication that is reasonably expected to delay the timeline for FDA review of the NDA in accordance with 21 C.F.R. 314.60; and (iv) a reasonable opportunity to review and comment on any Major Amendment (such review and comment to occur within the five Business Day period after Parent’s receipt of such Major Amendment as contemplated in clause (ii)) and on any communication or proposed response to any communication with the FDA referenced in clause (iii).

(c) From and after the date of this Agreement until the Effective Time, the Company agrees to provide Parent with advance written notice of the Company’s intent to enter into or amend any material supply or manufacturing Contracts at least ten Business Days prior to entering into or amending such Contracts.

5.6 Public Announcements. Each of the Company, Parent and the Purchaser agrees that no public release or announcement concerning the transactions contemplated hereby shall be issued by any party without the prior written consent of the Company and Parent (which consent shall not be unreasonably withheld or delayed), except as such release or announcement may be required by applicable Law or the rules or regulations of any applicable United States securities exchange or regulatory or governmental body to which the relevant party is subject, in which case the party required to make the release or announcement shall use its commercially reasonable efforts to allow each other party reasonable time to comment on such release or announcement in advance of such issuance. The Company, Parent and the Purchaser agree that the press release announcing the execution and delivery of this Agreement shall be a joint release of, and shall not be issued prior to the approval of each of, the Company and Parent.

5.7 Employee Benefit Matters.

(a) From and after the Closing Date, and subject to the provisions of this Section 5.7, Parent shall provide Company Employees who remain employed by Parent following the Closing Date compensation opportunities and types of benefits that are substantially comparable in the aggregate (excluding equity-based compensation) to those provided to similarly situated employees of Parent, pursuant to compensation and benefit plans sponsored by Parent or its affiliates (“Parent Benefit Plans”). Except as expressly provided herein, nothing herein is intended to limit the right of Parent, Purchaser, or the Surviving Corporation to (A) terminate the employment of any Company Employee at any time, (B) change or modify any incentive compensation or employee benefit plan or arrangement at any time and in any manner, or (C) change or modify the terms or conditions of employment for any of their employees.

(b) Notwithstanding anything in Section 5.7(a) to the contrary, the Company shall, upon Parent’s written request delivered not less than fifteen days before the Closing Date, terminate the Company’s qualified defined contribution retirement plan (the “Company 401(k) Plan”) effective as of the day before the Closing Date (the “Plan Termination Date”). In the event of such request, (i) the Company shall amend the Company 401(k) Plan and/or take such other action as is necessary so that the account balances of affected participants shall become fully vested and non-forfeitable to the extent required under applicable Law as of the Plan Termination Date, (ii) all employee and employer contributions under the Company 401(k) Plan shall cease of the Plan Termination Date, and (iii) the trustee of the Company 401(k) plan shall not accept contributions to the Company 401(k) Plan other than contributions made on behalf of participants that are based on compensation earned prior to the Plan Termination Date and repayments of participant loans. In the event the Company terminates the

41

Company 401(k) Plan pursuant to Parent’s written request, Parent agrees to accept the individual employee-requested rollovers of 401(k) account balances (including outstanding loans) from Company Employees into Parent’s defined contribution retirement plan.

(c) Parent shall, or shall cause the Surviving Corporation to, recognize all service of the Company Employees with the Company or a Company Subsidiary for purposes of vesting, eligibility to participate, and level of benefits under all Parent Benefit Plans in which such Company Employees may be eligible to participate after the Closing Date, including, but not limited to accrual of vacation using Parent’s vacation policy, except that prior service with the Company or a Company Subsidiary shall not be recognized for purposes of eligibility to receive the employer contribution (other than any employer matching contributions) into the defined contribution retirement plan or tuition reimbursement sponsored by Parent. In addition, for purposes of each Parent Benefit Plan providing medical, dental, pharmaceutical or vision benefits, Parent shall cause all pre-existing condition exclusions and actively-at-work requirements (except for life, disability and accidental death and dismemberment insurances) of such Parent Benefit Plan to be waived for the Company Employees and their covered dependents, and Parent shall cause any eligible expenses incurred by any Company Employee and his or her covered dependents prior to such Covered Employee’s participation in the corresponding Parent Benefit Plan to be taken into account under such Parent Benefit Plan for purposes of satisfying all deductible and maximum out-of-pocket requirements for the applicable plan year, in each case as permitted by the terms and conditions of the Parent Benefit Plans.

(d) From and after the Acceptance Time, the Company or the Surviving Corporation, as applicable, will, and Parent will cause the Company or the Surviving Corporation to, honor, in accordance with their terms, all individual employment, severance and change of control agreements between the Company and any Company Employee, including bonuses and/or incentive compensation in existence on the date hereof, unless such agreements are superseded by agreements with Parent.

(e) This Section 5.7 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 5.7, express or implied, is intended to confer upon any other Person (including but not limited to Company Employees) any rights or remedies of any nature whatsoever under or by reason of this Section 5.7.

(f) If the Company enters into additional Company Compensation Arrangements after the date hereof and prior to the Effective Time, in compliance with the terms of this Agreement, the Compensation Committee of the Company Board shall promptly approve each Company Compensation Arrangement as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(1) under the Exchange Act and take all other action necessary to satisfy the requirements of the non-exclusive safe-harbor with respect to such Company Compensation Arrangements in accordance with Rule 14d-10(d)(2) under the Exchange Act.

5.8 Indemnification of Directors and Officers.

(a) For a period of six years from and after the Effective Time, Parent and the Surviving Corporation shall indemnify and hold harmless all past and present directors, officers and employees of the Company to the same extent such Persons are indemnified as of the date of this Agreement by the Company pursuant to applicable Law, the Company Certificate, the Company Bylaws and indemnification agreements, if any, in existence on the date of this Agreement with any directors, officers and employees of the Company arising out of acts or omissions in their capacity as directors, officers or employees of the Company or any Company Subsidiary occurring at or prior to the Effective Time. Parent and the Surviving Corporation shall advance expenses (including reasonable legal fees and expenses) incurred in the defense of any claims, action, suit, proceeding or investigation with respect to the matters subject to indemnification pursuant to this Section 5.8(a) in accordance with the procedures set forth in the Company Certificate, the Company Bylaws and indemnification agreements, if any, in existence on the date of this Agreement; provided, however, that the

42

director, officer or employee of the Company to whom expenses are advanced undertakes to repay such advanced expenses to Parent and the Surviving Corporation within five Business Days if it is ultimately determined that such director, officer or employee is not entitled to indemnification pursuant to this Section 5.8(a).

(b) For a period of six years from and after the Effective Time, Parent shall cause the certificate of incorporation and bylaws of the Surviving Corporation to contain provisions no less favorable with respect to exculpation, indemnification and advancement of expenses of directors, officers and employees of the Company for periods at or prior to the Effective Time than are currently set forth in the Company Certificate and the Company Bylaws. Parent shall cause the indemnification agreements, if any, in existence on the date of this Agreement with any of the directors, officers or employees of the Company to continue in full force and effect in accordance with their terms following the Effective Time.

(c) For six years from and after the Effective Time, Parent shall cause the Surviving Corporation to maintain for the benefit of the Company’s directors and officers, as of the date of this Agreement and as of the Effective Time, an insurance and indemnification policy that provides coverage for events occurring prior to the Effective Time (the “D&O Insurance”) that is substantially equivalent to and in any event not less favorable in the aggregate than the Company’s existing policy (true and complete copies which have been previously provided to Parent) or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that the Surviving Corporation shall not be required to pay an annual premium for the D&O Insurance in excess of 300% of the last annual premium paid prior to the date of this Agreement. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if prepaid policies have been obtained prior to the Effective Time, which policies provide such directors and officers with coverage for an aggregate period of six years with respect to claims arising from facts or events that occurred on or before the Effective Time, including in respect of the transactions contemplated by this Agreement. If such prepaid policies have been obtained prior to the Effective Time, Parent shall cause the Surviving Corporation to maintain such policies in full force and effect, and continue to honor the obligations thereunder.

(d) In the event Parent or the Surviving Corporation (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then proper provision shall be made so that such continuing or surviving corporation or entity or transferee of such assets, as the case may be, shall assume the obligations set forth in this Section 5.8.

(e) The obligations under this Section 5.8 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 5.8 applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 5.8 applies shall be third party beneficiaries of this Section 5.8).

5.9 State Takeover Laws. The Company and the Company Board shall take no action to cause any “control share acquisition”, “fair price”, “business combination” or other anti-takeover Law to become applicable to the Company, Parent, the Purchaser, the Offer, the Merger, the Top-Up Option or any of the other transactions contemplated by this Agreement, and, if any such Law becomes or is deemed to be applicable to the Company, Parent or the Purchaser, the Offer, the Merger, the Top-Up Option or any of the other transactions contemplated by this Agreement, including the acquisition of Shares pursuant thereto, or the Support Agreements or any other transaction contemplated by this Agreement, then the Company and the Company Board shall take all action necessary to render such Law inapplicable to the foregoing.

5.10 Parent Agreement Concerning the Purchaser. Parent agrees to cause the Purchaser to comply with its obligations under this Agreement.

5.11 Section 16 Matters. Prior to the Effective Time, the Company Board, or an appropriate committee of non-employee directors thereof, shall adopt a resolution consistent with the interpretive guidance of the SEC so

43

that the disposition by any officer or director of the Company who is a covered Person of the Company for purposes of Section 16 of the Exchange Act and the rules and regulations thereunder (“Section 16”) of Shares or Company Options pursuant to this Agreement, and the Offer and the Merger shall be an exempt transaction for purposes of Section 16.

ARTICLE 6

(c) By either the Company or Parent, if the Offer (as it may have been extended pursuant to Section 1.1) expires as a result of the non-satisfaction of any condition to the Offer set forth in Annex I or is terminated or withdrawn pursuant to its terms without any Shares being purchased thereunder; provided, however, that the right to terminate this Agreement pursuant to this Section 7.1(c) shall not be available to any party whose material breach of this Agreement has been the primary cause or primarily resulted in the non-satisfaction of any condition to the Offer set forth in Annex I or the termination or withdrawal of the Offer pursuant to its terms without any Shares being purchased thereunder;

7.2 Effect of Termination.

(a) In the event of termination of this Agreement by either the Company or Parent as provided in Section 7.1, this Agreement shall forthwith become void and there shall be no liability or obligation on the part of Parent, the Purchaser or the Company or their respective Subsidiaries, officers or directors except (a) with

45

respect to Section 5.2(b), Section 5.6, this Section 7.2 and Article 8 and (b) with respect to any liabilities or damages incurred or suffered by a party as a result of the willful and material breach by another party of any of its representations, warranties, covenants or other agreements set forth in this Agreement or based on fraud.

(b) In the event that this Agreement is terminated pursuant to Section 7.1(e) or Section 7.1(f), then the Company shall pay to Parent concurrent with such termination, in the case of a termination by the Company, or within two Business Days thereafter, in the case of a termination by Parent, a termination fee of $36,000,000 (the “Breakup Fee”).

(c) In the event that this Agreement is terminated pursuant to Section 7.1(g), and prior to the date of termination of this Agreement an Acquisition Proposal shall have been made directly to the stockholders, otherwise publicly disclosed or otherwise publicly communicated to senior management of the Company or the Company Board, and on or prior to the first anniversary of the termination of this Agreement (i) such Acquisition Proposal is consummated, (ii) the Company enters into a definitive written agreement providing for the consummation of such Acquisition Proposal and such Acquisition Proposal is subsequently consummated (whether consummated before or after such anniversary), or (iii) the Company Board recommends or submits an Acquisition Proposal to its stockholders for adoption and such transaction is subsequently consummated (whether consummated before or after such anniversary), which, in the cases of clauses (i) through (iii), need not be the same Acquisition Proposal that shall have been made, publicly disclosed or communicated prior to termination hereof, then, concurrent with such consummation, the Company shall pay Parent the Breakup Fee (provided, that for purposes of this Section 7.2(c), the term “Acquisition Proposal” shall have the meaning assigned to such term in Section 8.4, except that the references to “25%” shall be deemed to be references to “50%”).

(d) All payments under this Section 7.2 shall be made by wire transfer of immediately available funds to an account designated in writing by Parent. Each of the Company, Parent and the Purchaser acknowledges that (i) the agreements contained in this Section 7.2 are an integral part of the transactions contemplated by this Agreement, (ii) without these agreements, Parent, the Purchaser and the Company would not enter into this Agreement and (iii) the Breakup Fee is not a penalty, but rather is liquidated damages in a reasonable amount that will compensate Parent and the Purchaser in the circumstances in which such Breakup Fee is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. If the Company fails promptly to pay the amounts due pursuant to this Section 7.2, and in order to obtain such payment, Parent or its designee commences a suit that results in a judgment against the Company for all or a portion of the Breakup Fee, the Company shall pay to Parent or its designees interest on such amount or amounts from the date such payment was required to be made until the payment date at the prime rate of Citibank, N.A., in effect on the date such payment was required to be made.

7.3 Amendment. Subject to Section 1.3(c), this Agreement may be amended by the Company, Parent and the Purchaser by action taken by or on behalf of their respective Boards of Directors at any time prior to the Effective Time; provided, however, that, after adoption of the Agreement by the Company’s stockholders, no amendment may be made which, by Law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders, without the approval of such stockholders in accordance with applicable Law. This Agreement may not be amended except by an instrument in writing signed by the parties hereto.

7.4 Waiver. Subject to Section 1.3(c), at any time prior to the Effective Time, Parent and the Purchaser, on the one hand, and the Company, on the other hand, may (i) extend the time for the performance of any of the obligations or other acts of the other, (ii) waive any uncured breaches of the representations and warranties of the other contained herein or in any document delivered pursuant hereto and (iii) waive compliance by the other with any of the agreements or conditions contained herein; provided, however, that after any approval of this Agreement by the Company’s stockholders, there may not be any extension or waiver of this Agreement which

46

decreases the Merger Consideration or which adversely affects the rights of the Company’s stockholders hereunder without the approval of such stockholders. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.
