AGREEMENT AND PLAN OF MERGER (hereinafter called this "Agreement"), dated as of September 2, 2012, among Medicis Pharmaceutical Corporation, a Delaware corporation (the "Company"), Valeant Pharmaceuticals International, a Delaware corporation ("Parent"), Merlin Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub," the Company and Merger Sub sometimes being hereinafter collectively referred to as the "Constituent Corporations"), and Valeant Pharmaceuticals International, Inc., a Canadian corporation ("Parent Holdco").

RECITALS

WHEREAS, the respective boards of directors of each of Parent, Merger Sub and the Company have approved the merger of Merger Sub with and into the Company (the "Merger") upon the terms and subject to the conditions set forth in this Agreement and have approved and declared advisable this Agreement; and

WHEREAS, the Company, Parent and Merger Sub desire to make certain representations, warranties, covenants and agreements in connection with this Agreement.

NOW, THEREFORE, in consideration of the premises, and of the representations, warranties, covenants and agreements contained herein, the parties hereto agree as follows:

ARTICLE I

The Merger; Closing; Effective Time

1.1. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into the Company and the separate corporate existence of Merger Sub shall thereupon cease. The Company shall be the surviving corporation in the Merger (sometimes hereinafter referred to as the "Surviving Corporation"), and the separate corporate existence of the Company, with all its rights, privileges, immunities, powers and franchises, shall continue unaffected by the Merger, except as set forth in Article II. The Merger shall have the effects specified in the Delaware General Corporation Law, as amended (the "DGCL").

1.2. Closing. Unless otherwise mutually agreed in writing between the Company and Parent, the closing for the Merger (the "Closing") shall take place at the offices of Sullivan & Cromwell LLP, 1888 Century Park East, 21^st Floor, Los Angeles, California, at 9:00 A.M. on the fourth (4th) business day (the "Closing Date") following the day on which the last to be satisfied or waived of the conditions set forth in Article VII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions) shall be satisfied or

-1-

waived in accordance with this Agreement; provided, however, that, notwithstanding the satisfaction or waiver of the conditions set forth in Article VII, Parent and Merger Sub shall not be obligated to effect the Closing prior to the second (2nd) business day following the final day of the Marketing Period, unless Parent shall request an earlier date on two (2) business days prior written notice (but, subject in such case, to the satisfaction or waiver of the conditions set forth in Article VII (other than any such conditions which by their terms cannot be satisfied until the Closing Date, which shall be required to be so satisfied or waived on Parent's requested Closing Date)). For purposes of this Agreement, the term "business day" shall mean any day ending at 11:59 p.m. (Eastern Time) other than a Saturday or Sunday or a day on which banks are required or authorized to close in the City of New York. "Marketing Period" shall mean the first period of twenty (20) consecutive calendar days, commencing not less than two (2) days after the delivery of the Required Information, throughout which (a) Parent shall have the Required Information that the Company is required to provide to Parent pursuant to Section 6.14; provided that if the Company shall in good faith reasonably believe it has provided the Required Information, it may deliver to Parent a written notice to that effect (stating when it believes it completed such delivery), in which case the Company shall be deemed to have complied with this clause (a) unless Parent in good faith reasonably believes the Company has not completed the delivery of the Required Information and, within four (4) business days after the delivery of such notice by the Company, delivers a written notice to the Company to that effect (stating with specificity which Required Information the Company has not delivered); for the avoidance of doubt, the Marketing Period shall begin when the Company has provided such information and (b) prior to the completion of such twenty (20) consecutive calendar day period, Ernst & Young LLP shall not have withdrawn or qualified its audit opinion with respect to any of the Required Information; provided, that the Marketing Period shall end on any earlier date that is the date on which the Debt Financing or the Bond Financing, as applicable, is consummated, and, for purposes of such Marketing Period (i) the days from and including November 21, 2012 through November 25, 2012 shall not be considered calendar days and (ii) if such period has not ended prior to December 20, 2012, such period shall be deemed not to have commenced until January 2, 2013.

1.3. Effective Time. As soon as practicable following the Closing, the Company and Parent will cause a Certificate of Merger (the "Delaware Certificate of Merger") to be executed, acknowledged and filed with the Secretary of State of the State of Delaware as provided in Section 251 of the DGCL. The Merger shall become effective at the time when the Delaware Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or at such later time as may be agreed by the parties in writing and specified in the Delaware Certificate of Merger (the "Effective Time").

ARTICLE II

Certificate of Incorporation and By-Laws

of the Surviving Corporation

2.1. The Certificate of Incorporation. At the Effective Time, the certificate of incorporation of the Surviving Corporation (the "Charter") shall be amended in its entirety to be identical to the certificate of incorporation of Merger Sub, until thereafter amended as provided therein or by applicable Law (as defined in Section 5.1(i)).

2.2. The By-Laws. The parties hereto shall take all actions necessary so that the by-laws of Merger Sub in effect immediately prior to the Effective Time shall be the by-laws of the Surviving Corporation (the "By-Laws"), until thereafter amended as provided therein or by applicable Law.

ARTICLE III

Directors and Officers of the Surviving Corporation

3.1. Directors and Officers. The parties hereto shall take all actions necessary so that (a) the board of directors of Merger Sub at the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Charter and the By-Laws and (b) the officers of the Company at the Effective Time shall, from and after the Effective Time, be the officers of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Charter and the By-Laws.

ARTICLE IV

Effect of the Merger on Capital Stock;

Exchange of Certificates

4.1. Effect on Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of the holder of any capital stock of the Company:

(a) Merger Consideration. Each share of the Class A Common Stock, par value $0.014 per share, of the Company (a "Share" or, collectively, the "Shares") issued and outstanding immediately prior to the Effective Time (other than (i) Shares owned by Parent Holdco, Merger Sub or any other direct or indirect wholly owned subsidiary of Parent Holdco and Shares owned by the Company, and in each case not held on behalf of third parties, and (ii) Shares that are owned by stockholders ("Dissenting Stockholders") who have perfected and not withdrawn a demand for appraisal rights pursuant to Section 262 of the DGCL (each, an "Excluded Share" and

-3-

collectively, "Excluded Shares")) shall be converted into the right to receive $44.00 per Share (the "Per Share Merger Consideration"). At the Effective Time, all of the Shares shall cease to be outstanding, shall be cancelled and shall cease to exist, and each certificate (a "Certificate") formerly representing any of the Shares and each non-certificated share represented by book entry (a "Book Entry Share") (other than, in each case, Excluded Shares) shall thereafter represent only the right to receive the Per Share Merger Consideration, without interest.

(b) Cancellation of Excluded Shares. Each Excluded Share shall, by virtue of the Merger and without any action on the part of the holder of the Excluded Share, cease to be outstanding, be cancelled without payment of any consideration therefor and shall cease to exist, subject to any rights the holder thereof may have under Section 4.2(f) and the DGCL.

(c) Merger Sub. At the Effective Time, each share of Common Stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock, par value $0.01 per share, of the Surviving Corporation.

4.2. Exchange of Certificates.

(a) Paying Agent. At the Effective Time, Parent shall deposit, or shall cause to be deposited, with a paying agent selected by Parent with the Company's prior approval (such approval not to be unreasonably withheld or delayed) (the "Paying Agent"), for the benefit of the holders of Shares, a cash amount in immediately available funds necessary for the Paying Agent to make payments under Section 4.1(a) (such cash being hereinafter referred to as the "Exchange Fund"). The Paying Agent shall invest the Exchange Fund as directed by Parent; provided that such investments shall be in obligations of or guaranteed by the United States of America in commercial paper obligations rated A-1 or P-1 or better by Moody's Investors Service, Inc. or Standard & Poor's Corporation, respectively, in certificates of deposit, bank repurchase agreements or banker's acceptances of commercial banks with capital exceeding $1 billion, or in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of acquisition or a combination of the foregoing and, in any such case, no such instrument shall have a maturity exceeding three months. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable under Section 4.1(a) shall be promptly returned to Parent. No investment of the funds shall relieve Parent, the Surviving Corporation or the Paying Agent from making the payments required by this Article IV, and following any net losses from any such investment, Parent shall promptly provide additional funds to the Paying Agent for the benefit of the applicable holders of Shares immediately prior to the Effective Time in the amount of such net losses, which additional funds shall be deemed to be part of the funds. No investment of the funds shall have maturities that could prevent or delay payments to be made pursuant to this Agreement.

-4-

(b) Exchange Procedures. Promptly after the Effective Time (and in any event within two (2) business days), the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of Shares (other than holders of Excluded Shares) (i) a letter of transmittal in customary form specifying that delivery shall be effected, and risk of loss and title to the Certificates and Book Entry Shares shall pass, only upon delivery of the Certificates (or affidavits of loss in lieu of the Certificates as provided in Section 4.2(e)) or Book Entry Shares to the Paying Agent, such letter of transmittal to be in such form and have such other provisions as Parent and the Company may reasonably agree, and (ii) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu of the Certificates as provided in Section 4.2(e)) or Book Entry Shares in exchange for the Per Share Merger Consideration. Upon surrender of a Certificate (or affidavit of loss in lieu of the Certificate as provided in Section 4.2(e)) or Book Entry Shares to the Paying Agent in accordance with the terms of such letter of transmittal, duly executed, the holder of such Certificate or Book Entry Shares shall be entitled to receive in exchange therefor a cash amount in immediately available funds (after giving effect to any required Tax (as defined in Section 5.1(o)) withholdings as provided in Section 4.2(g)) equal to (A) the number of Shares represented by such Certificate (or affidavit of loss in lieu of the Certificate as provided in Section 4.2(e)) or Book Entry Shares multiplied by (B) the Per Share Merger Consideration and the Certificate or Book Entry Shares so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates or Book Entry Shares. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, a check for any cash to be exchanged upon due surrender of the Certificate or Book Entry Shares may be issued to such transferee if the Certificate or Book Entry Shares formerly representing such Shares is presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid or are not applicable.

(c) Transfers. From and after the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate is presented to the Surviving Corporation, Parent or the Paying Agent for transfer, it shall be cancelled and exchanged for the cash amount in immediately available funds to which the holder of the Certificate or Book Entry Shares is entitled pursuant to this Article IV.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments of the Exchange Fund) that remains unclaimed by the stockholders of the Company for one (1) year after the Effective Time shall be delivered to the Surviving Corporation. Any holder of Shares (other than Excluded Shares) who has not theretofore complied with this Article IV shall thereafter look only to the Surviving Corporation for payment of the Per Share Merger Consideration (after giving effect to any required Tax withholdings as provided in Section 4.2(g)) upon due surrender of its Certificates (or affidavits of loss in lieu of the Certificates) or Book Entry Shares, without any interest thereon. Notwithstanding the foregoing, none of the Surviving Corporation, Parent, the Paying Agent or any other

-5-

Person shall be liable to any former holder of Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. For the purposes of this Agreement, the term "Person" shall mean any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity (as defined in Section 5.1(d)(i)) or other entity of any kind or nature.

(e) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in customary amount and upon such terms as may be reasonably required by Parent as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent will issue a check in the amount (after giving effect to any required Tax withholdings as provided in Section 4.2(g)) equal to the number of Shares represented by such lost, stolen or destroyed Certificate multiplied by the Per Share Merger Consideration.

(f) Appraisal Rights. No Person who has perfected a demand for appraisal rights pursuant to Section 262 of the DGCL shall be entitled to receive the Per Share Merger Consideration with respect to the Shares owned by such Person unless and until such Person shall have effectively withdrawn or lost such Person's right to appraisal under the DGCL. Each Dissenting Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL with respect to Shares owned by such Dissenting Stockholder. The Company shall give Parent (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law that are received by the Company relating to stockholders' rights of appraisal and (ii) the opportunity to direct all negotiations and proceedings with respect to demand for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for appraisal, offer to settle or settle any such demands or approve any withdrawal of any such demands.

(g) Withholding Rights. Each of Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the "Code"), or any other applicable state, local or foreign Tax (as defined in Section 5.1(o)) Law. To the extent that amounts are so withheld by the Surviving Corporation, Parent or the Paying Agent, as the case may be, such withheld amounts (i) shall be remitted by Parent, the Surviving Corporation or the Paying Agent, as applicable, to the applicable Governmental Entity, and (ii) shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding was made by the Surviving Corporation, Parent or the Paying Agent, as the case may be. Parent, the Surviving Corporation or the Paying Agent, as applicable, shall provide commercially reasonable

-6-

notice to each applicable holder of Shares upon becoming aware of any such withholding obligation and shall cooperate with such holder to the extent reasonable to obtain reduction of or relief from such deduction and withholding.

4.3. Treatment of Stock Plans.

(a) Treatment of Options. Each option to purchase Shares granted under the Stock Plans (as defined in Section 5.1(b)(i)) (a "Company Option"), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall be cancelled and shall only entitle the holder thereof to receive, within eight (8) days following the Effective Time, an amount in cash equal to the product of (i) the total number of Shares subject to the Company Option multiplied by (ii) the excess, if any, of the Per Share Merger Consideration over the exercise price per Share under such Company Option less applicable Taxes required to be withheld with respect to such payment. For the avoidance of doubt, each Company Option that has an exercise price that equals or exceeds the Per Share Merger Consideration shall be cancelled and shall cease to exist without receiving any payment.

(b) Treatment of Stock Appreciation Rights. Each stock appreciation right relating to Shares granted under the Stock Plans (a "Company SAR"), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall be cancelled and shall only entitle the holder thereof to receive, within eight (8) days following the Effective Time, an amount in cash equal to the product of (i) the total number of Shares subject to the Company SAR multiplied by (ii) the excess, if any, of the Per Share Merger Consideration over the exercise price per Share under such Company SAR less applicable Taxes required to be withheld with respect to such payment. For the avoidance of doubt, each Company SAR that has an exercise price that equals or exceeds the Per Share Merger Consideration shall be cancelled and shall cease to exist without receiving any payment.

(c) Treatment of Restricted Shares. Each Share that is subject to restrictions and that was granted under the Stock Plans (a "Company Restricted Share"), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall only entitle the holder thereof to receive the Per Share Merger Consideration under Section 4.1(a) less applicable Taxes required to be withheld.

(d) Corporate Actions. At or prior to the Effective Time, the Company, the board of directors of the Company and the compensation committee of the board of directors of the Company, as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of Sections 4.3(a), 4.3(b) and 4.3(c). The Company shall take all actions necessary to ensure that from and after the Effective Time neither Parent nor the Surviving Corporation will be required to deliver Shares or other capital stock of the Company to any Person pursuant to or in settlement of Company Options, Company SARs or Company Restricted Shares.

4.4. Adjustments to Prevent Dilution. In the event that the Company changes the number of Shares or securities convertible or exchangeable into or

-7-

exercisable for Shares issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer, or other similar transaction, the Per Share Merger Consideration shall be equitably adjusted.

ARTICLE V

Except as set forth in the Company Reports (as defined below) filed with the SEC since January 1, 2011 and publicly available prior to the date of this Agreement (excluding, in each case, any disclosures set forth in any risk factor section or in any other section to the extent they are forward-looking statements or cautionary, predictive or forward-looking in nature) or in the corresponding sections of the disclosure schedule delivered to Parent by the Company immediately prior to entering into this Agreement (the "Company Disclosure Schedule") (it being agreed that disclosure of any item in any section of the Company Disclosure Schedule shall be deemed disclosure with respect to any other section to the extent (and only to the extent) that the relevance of such item is reasonably apparent from the face of such disclosure), the Company hereby represents and warrants to Parent and Merger Sub that:

The Company has delivered to Parent complete and correct copies of the Company's and its Subsidiaries' certificates of incorporation and by-laws or comparable governing documents, each as amended to the date of this Agreement, and each as so delivered is in full force and effect.

-8-

(B) changes that are the result of factors generally affecting the pharmaceutical industry;

(D) any geopolitical conditions, the outbreak or escalation of hostilities, any acts of war, sabotage, terrorism or military actions, or any escalation or worsening of any such hostilities, acts of war, sabotage, terrorism or military actions threatened or underway as of the date of this Agreement;

(E) any general regulatory, legislative or political conditions or securities, credit, financial or other capital market conditions, in each case in the United States or any foreign jurisdiction;

(F) changes in Law, including rules, regulations and administrative policies of the FDA or interpretations thereof, in each case of general applicability;

(G) any legal proceedings made or brought by any of the current or former securityholders of the Company (on their own behalf or on behalf of the Company) arising out of or related to this Agreement or any of the transactions contemplated hereby;

(H) earthquakes, hurricanes, tornados or other natural disasters;

(I) a decline in the price of the Shares on the New York Stock Exchange ("NYSE"), provided that the exception in this clause shall not prevent or otherwise affect a determination that any change, effect, circumstance or development underlying such decline has resulted in, or contributed to, a Company Material Adverse Effect;

(J) the announcement or pendency of this Agreement or the transactions contemplated hereby, including the effect on employees, customers, suppliers, distributors and collaboration partners;

(K) any failure by the Company to meet any estimates of revenues or earnings or other financial or operating metrics (whether such projections were made by the Company or independent third parties) for any period ending on or after the date of this Agreement and prior to the Closing, provided that the exception in this clause shall not prevent or otherwise affect a

-9-

determination that any change, effect, circumstance or development underlying such failure has resulted in, or contributed to, a Company Material Adverse Effect;

(L) the approval or disapproval by, or the delay of a determination of approval or disapproval by, the FDA or any Governmental Entity, or any panel or advisory body empowered or appointed thereby, with respect to the Company Products; and

(M) any action expressly required to be taken or not taken with the consent of Parent or pursuant to or in accordance with this Agreement;

provided, further, that, with respect to clauses (A), (B), (C), (D), (E) and (F), such change, event, circumstance or development does not (i) primarily relate only to (or have the effect of primarily relating to) the Company and its Subsidiaries or (ii) have a disproportionate adverse effect on the Company and its Subsidiaries compared to other companies of similar size operating in the pharmaceutical industry.

The Company maintains internal control over financial reporting (as defined in Rule 13a-15 or 15d-15, as applicable, under the Exchange Act). Such internal control over financial reporting is effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on its financial statements.

(vi) Excluding non-material routine claims for benefits, there is no action, suit, audit, claim, proceeding or, to the knowledge of the Company, investigation pending against or involving or threatened against any Benefit Plan before any court or arbitrator or any Governmental Entity, or federal, state or local official that would, individually or in the aggregate, reasonably be likely to subject the Company or any of its Subsidiaries to a material liability.

(vii) Except for the cash-out of equity compensation awards under Section 4.3, none of the execution of this Agreement, the stockholder adoption of this Agreement or the consummation of the transactions contemplated hereby, will (whether alone or in connection with any other event(s)) (A) entitle any employee of the Company or any of its Subsidiaries to severance pay or any increase in severance pay (or other compensation or benefits) upon any termination of employment, (B) accelerate the time of payment or vesting or result in any payment or funding (through a grantor trust or otherwise) of any compensation or benefits under, or materially increase the amount payable under any of the Benefit Plans or result in any other material obligation pursuant to, any of the Benefit Plans, (C) limit or restrict the right of the Company or any of its Subsidiaries or, after the consummation of the transactions contemplated hereby, Parent or any of its Subsidiaries, to merge, amend or terminate any of the Benefit Plans, (D) result in payments under any of the Benefit Plans or otherwise which would constitute an "excess parachute payment" within the meaning of Section 280G of the Code or would disqualify any amount from being qualified performance-based compensation within the meaning of Section 162(m) of the Code; or (E) result in any material breach or other material violation of or under any employment agreement, or any other labor-related agreement concerning the employees of the Company or to which any of the Company or any of its Subsidiaries is a party or by which any such entity is bound.

(viii) There has been no amendment to, announcement by the Company or any of its Subsidiaries relating to, or change in employee participation or coverage under, any Benefit Plan which would increase materially the expense of maintaining such plan above the level of the expense incurred therefor for the most recent plan year.

Each Foreign Benefit Plan which, under the Laws of any jurisdiction outside of the United States, is required to be registered or approved by any governmental entity or agency, has been so registered and approved and has been maintained in good standing in all material respects with applicable governmental entities or agencies, and if intended to qualify for special tax treatment, meets all requirements for such treatment in all material respects.

This Agreement has been duly executed and delivered by each of Parent and Merger Sub and is a valid and binding agreement of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with its terms, subject to the Bankruptcy and Equity Exception.

(i) Assuming the truth and completeness of the representations and warranties of the Company contained in this Agreement, other than the filings and/or notices pursuant to Section 1.3 and under the HSR Act (the "Parent Approvals"), no notices, reports or other filings are required to be made by Parent or Merger Sub with, nor are any consents, registrations, approvals, permits or authorizations required to be obtained by Parent or Merger Sub from, any

-35-

Governmental Entity in connection with the execution, delivery and performance of this Agreement by Parent and Merger Sub and the consummation by Parent and Merger Sub of the Merger and the other transactions contemplated hereby, except those that the failure to make or obtain would not, individually or in the aggregate, reasonably be expected to prevent or materially delay the ability of Parent or Merger Sub to consummate the Merger and the other transactions contemplated by this Agreement.

(ii) The execution, delivery and performance of this Agreement by Parent and Merger Sub do not, and the consummation by Parent and Merger Sub of the Merger and the other transactions contemplated hereby will not, constitute or result in (A) a breach or violation of, or a default under, the certificate of incorporation or by-laws of Parent or Merger Sub or the comparable governing instruments of any of their respective Subsidiaries, (B) with or without notice, lapse of time or both, a breach or violation of, a termination (or right of termination) or a default under, the creation or acceleration of any obligations under or the creation of a Lien on any of the assets of Parent or any of its Subsidiaries pursuant to, any Contracts binding upon Parent or any of its Subsidiaries or any Laws or governmental or non-governmental permit or license to which Parent or any of its Subsidiaries is subject; or (C) any change in the rights or obligations of any party under any of such Contracts, except, in the case of clause (B) or (C) above, for any breach, violation, termination, default, creation, acceleration or change that would not, individually or in the aggregate, reasonably be expected to prevent or materially delay the ability of Parent or Merger Sub to consummate the Merger and the other transactions contemplated by this Agreement.

(d) Available Funds. As of the Effective Time, Parent and Merger Sub will have available to them, directly or through one or more Affiliates, all funds necessary to consummate the Merger and for the payment to the Paying Agent of the aggregate Per Share Merger Consideration and to satisfy all of their obligations under this Agreement. Parent has delivered to the Company true, complete and correct copies, including all exhibits, schedules or amendments thereto, of the fully executed commitment letter, dated as of the date hereof, among Parent Holdco, Parent, JPMorgan Chase Bank, N.A. and J.P. Morgan Securities LLC (collectively, the "Lender Parties") (the "Debt Commitment Letter"), pursuant to which the Lender Parties have committed, upon the terms and subject to the conditions set forth therein, to lend the amounts set forth in the Debt Commitment Letter (the "Debt Financing"). The Debt Commitment Letter has not been amended or modified in any manner prior to the date of this Agreement. Neither Parent Holdco, Parent nor Merger Sub has entered into any agreement, side letter or other arrangement relating to the financing of the payments to be made by them at the Effective Time or transactions contemplated by this Agreement, other than as set forth in the Debt Commitment Letter and the fee letter and engagement letters related thereto. The Debt Commitment Letter is in full force and effect and represents a valid, binding and enforceable obligation of Parent Holdco and Parent and, to the knowledge of the Parent, Parent Holdco and Merger Sub, the Lender Parties, to

-36-

provide the financing contemplated thereby subject only to the satisfaction or waiver of the conditions precedent set forth in the Debt Commitment Letter and, subject to the qualification that such enforceability may be limited by bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting rights of creditors. Parent Holdco and Parent have fully paid (or caused to be paid) any and all commitment fees and other amounts, if any, that are due and payable on or prior to the date of this Agreement in connection with the Debt Financing. As of the date of this Agreement, assuming the accuracy of the representations and warranties set forth in Section 5.1 such that the condition set forth in Section 7.2(a) is satisfied, no event has occurred which, with or without notice, lapse of time or both, would constitute a breach or default on the part of Parent Holdco or Parent, or, to the knowledge of Parent Holdco, Parent or Merger Sub, the Lender Parties thereto under the Debt Commitment Letter. As of the date of this Agreement, assuming the accuracy of the representations and warranties set forth in Section 5.1 such that the condition set forth in Section 7.2(a) is satisfied, and the performance by the Company of its obligations under this Agreement, neither Parent Holdco, Parent nor Merger Sub has any reason to believe that they or the Lender Parties will be unable to satisfy on a timely basis any term of the Debt Commitment Letter and the fee letters. There are no conditions precedent or other contingencies related to the funding of the full amount of the Debt Financing, other than the conditions precedent set forth in the Debt Commitment Letter and the Fee Letter (as defined in the Debt Commitment Letter). Parent Holdco, Parent and Merger Sub understand and acknowledge that under the terms of this Agreement, Parent's and Merger Sub's obligations to consummate the Merger are not in any way contingent upon or otherwise subject to Parent Holdco's, Parent's or Merger Sub's consummation of any financing arrangements, Parent Holdco's, Parent's or Merger Sub's obtaining of any financing or the availability, grant, provision or extension of any financing to Parent Holdco, Parent or Merger Sub.

(e) Proxy Statement. The information supplied by or on behalf of Parent, Merger Sub or any of their respective Affiliates or agents in writing, expressly for inclusion in the Proxy Statement will not, on the date of filing with the SEC or at the time the Proxy Statement is first mailed to the stockholders of the Company, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. Neither Parent nor Merger Sub makes any representation or warranty with respect to any information supplied by any other Person that is included in the Proxy Statement.

(f) Ownership of Merger Sub; No Prior Activities. Parent owns one hundred percent (100%) of the issued and outstanding capital stock of Merger Sub. Merger Sub was formed solely for the purpose of engaging in the transactions contemplated by this Agreement. Except for obligations or liabilities incurred in connection with its formation and the transactions contemplated by this Agreement, Merger Sub has not and will not have incurred, directly or indirectly, through any Subsidiary or Affiliate or otherwise, any obligations or liabilities or engaged in any business activities of any type or kind whatsoever or entered into any agreements or arrangements with any Person.

-37-

(g) Litigation. As of the date hereof, (i) there is no pending (or, to the knowledge of Parent, threatened in writing) Action before any Governmental Entity to which Parent or any of its Subsidiaries is a party or any Action by any Governmental Entity against or involving Parent or any of its Subsidiaries and (ii) neither Parent nor any of its Subsidiaries is subject to any outstanding Order, in each case that would, individually or in the aggregate, reasonably be expected to prevent or materially delay the ability of Parent or Merger Sub to consummate the Merger and the other transactions contemplated by this Agreement.

(h) Interested Stockholder. None of Parent, Merger Sub nor any of their respective Affiliates is, or has been at any time during the period commencing three (3) years prior to the date hereof through the date hereof, an "interested stockholder" of the Company, as such term is defined in Section 203 of the DGCL. As of the date of this Agreement, neither Parent nor any of its Subsidiaries owns (beneficially or otherwise) any shares of Common Stock or any other equity interests in the Company or any options, warrants or other rights to acquire Common Stock or any other equity interests in the Company (or any other economic interest through derivative securities or otherwise in the Company).

(i) Broker. The Company will not be responsible for any brokerage, finder's, financial advisor's or other fee or commission payable in connection with the transactions contemplated by this Agreement based upon arrangements made by and on behalf of Parent and Merger Sub.

(j) No Other Representations or Warranties. Except for the representations and warranties in this Section 5.2, neither Parent, Merger Sub nor any Person on behalf of Parent or Merger Sub makes any express or implied representation or warranty with respect to Parent or Merger Sub or with respect to any other information provided to the Company in connection with the transactions contemplated hereby.

6.2. Acquisition Proposals.

(a) No Solicitation or Negotiation. The Company agrees that, except as expressly permitted by this Section 6.2, neither it nor any of its Subsidiaries nor any of the officers and directors of it or its Subsidiaries shall, and that it shall use its commercially reasonable efforts to instruct and cause its and its Subsidiaries' employees, investment bankers, attorneys, accountants and other advisors or representatives (such directors, officers, employees, investment bankers, attorneys, accountants and other advisors or representatives, collectively, "Representatives") not to, directly or indirectly:

(i) initiate, solicit or knowingly facilitate or encourage any inquiries or the making of any Acquisition Proposal (as defined below); or

(ii) engage in, continue or otherwise participate in any discussions or negotiations regarding, or provide any non-public information or data to, or cooperate in any way with, any Person relating to, any Acquisition Proposal or any inquiry or proposal that could reasonably be expected to lead to any Acquisition Proposal; or

(iii) waive, terminate, modify or fail to enforce any "standstill" or confidentiality or similar obligation of any Person (other than any party hereto) with respect to the Company or any of its Subsidiaries.

Notwithstanding anything in the foregoing to the contrary, prior to the time, but not after, the Requisite Company Vote is obtained, the Company may (A) provide information in response to a request therefor by a Person who has made an unsolicited bona fide written Acquisition Proposal providing for a merger or consolidation or acquisition of assets representing at least 50% of the consolidated revenues, net income or assets of the Company or more than 50% of the total voting power of the equity securities of the Company; provided, that (x) prior to providing such information, the Company enters into a confidentiality agreement with such Person on terms not less restrictive to such Person than those contained in the Confidentiality Agreement (as defined in Section 6.5(c)) and (y) such confidentiality agreement shall not prohibit the Company from providing any information to Parent and such confidentiality agreement need not contain a standstill provision, and the Company promptly discloses (and, if applicable, provides copies of) any such information to Parent to the extent not previously provided to Parent; (B) engage or participate in any discussions or negotiations with any Person who has made such an unsolicited bona fide written Acquisition Proposal; or (C) after having complied with Section 6.2(c), approve, recommend, or otherwise declare advisable or propose to approve, recommend or declare advisable (publicly or otherwise) such an Acquisition Proposal, if and only to the extent that, (I) such Acquisition Proposal was not solicited, initiated, encouraged or facilitated in breach of this Section 6.2, (II) prior to taking any action described in clause (A), (B) or (C) above, the board of directors of the Company determines in good faith after consultation with outside legal counsel that failure to take such action would be inconsistent with the directors' fiduciary duties under applicable Law, (III) in each such case referred to in clause (A) or (B) above, the board of directors of the Company has determined in good faith based on the information then available and after consultation

-43-

with its financial advisor that such Acquisition Proposal either constitutes a Superior Proposal (as defined below) or is reasonably likely to result in a Superior Proposal, and (IV) in the case referred to in clause (C) above, the board of directors of the Company determines in good faith (after consultation with its financial advisor and outside legal counsel) that such Acquisition Proposal is a Superior Proposal. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 6.2(a) by any Representative of the Company or any of its Subsidiaries, whether or not such person is purporting to act on behalf of the Company or otherwise, shall be deemed to be a breach of this Section 6.2(a) by the Company. Notwithstanding the foregoing, the Company and its Representatives may in any event have discussions with any Person solely to clarify and understand the terms and conditions of any inquiry or proposal made by such Person.

(b) Definitions. For purposes of this Agreement:

"Acquisition Proposal" means (i) any proposal or offer with respect to a merger, joint venture, partnership, consolidation, dissolution, liquidation, tender offer, recapitalization, reorganization, share exchange, business combination or similar transaction involving the Company or any of its Subsidiaries and (ii) any acquisition by any person resulting in, or proposal or offer, which if consummated would result in, any person becoming the beneficial owner of, directly or indirectly, in one or a series of related transactions, 20% or more of the total voting power or of any class of equity securities of the Company or those of any of its Subsidiaries, or assets (including, without limitation, equity securities of its Subsidiaries) representing 20% or more of the consolidated revenues, net income or assets of the Company, in each case other than the transactions contemplated by this Agreement.

"Superior Proposal" means an unsolicited bona fide Acquisition Proposal that would result in any person becoming the beneficial owner, directly or indirectly, of assets representing more than 50% of the consolidated revenues, net income or assets of the Company or more than 50% of the total voting power of the equity securities of the Company that the board of directors of the Company has determined in its good faith judgment is reasonably likely to be consummated in accordance with its terms, taking into account all legal, financial, regulatory and other aspects of the proposal and the Person making the proposal, and if consummated, would result in a transaction more favorable to the Company's stockholders from a financial point of view than the transaction contemplated by this Agreement (after taking into account any revisions to the terms of the transaction contemplated by Section 6.2(c) of this Agreement and the time likely to be required to consummate such Acquisition Proposal).

(c) No Change in Recommendation or Alternative Acquisition Agreement. The board of directors of the Company and each committee of the board of directors shall not:

(i) withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify), in a manner adverse to Parent,

-44-

the Company Recommendation with respect to the Merger (it being understood that the board of directors may take no position with respect to an Acquisition Proposal until the earlier of the close of business as of (A) the day prior to the Stockholders Meeting and (B) the tenth business day after the commencement of such Acquisition Proposal pursuant to Rule 14d-2 under the Exchange Act without such action being considered an adverse modification); or

(ii) except as expressly permitted by, and after compliance with, Section 8.3(a) hereof, cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (other than a confidentiality agreement referred to in Section 6.2(a) entered into in compliance with Section 6.2(a)) (an "Alternative Acquisition Agreement") relating to any Acquisition Proposal.

Notwithstanding anything to the contrary set forth in this Agreement, prior to the time, but not after, the Requisite Company Vote is obtained, the board of directors of the Company may withhold, withdraw, qualify or modify the Company Recommendation or approve, recommend or otherwise declare advisable any Superior Proposal made after the date of this Agreement that was not solicited, initiated, encouraged or facilitated in breach of Section 6.2 of this Agreement, if the board of directors of the Company determines in good faith, after consultation with outside counsel, that failure to take such action would be inconsistent with the directors' fiduciary duties under applicable Law (a "Change of Recommendation"); provided, however, that no Change of Recommendation may be made until after at least three (3) business days following Parent's receipt of notice from the Company advising that management of the Company currently intends to recommend to its board of directors that it take such action and the basis therefor, including all necessary information under Section 6.2(f). In addition, the Company may not exercise its termination rights pursuant to Section 8.3(a) unless, in addition to the conditions set forth in Section 8.3(a), (i) the Company notifies Parent in writing that it intends to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal, which notice shall include all of the necessary information under Section 6.2(f) and (ii) Parent does not make, within three (3) business days of receipt of the Company's written notification of its intention to enter into a binding agreement for a Superior Proposal, an offer that the board of directors of the Company determines, in good faith after consultation with its financial advisors, is at least as favorable, from a financial point of view, to the stockholders of the Company as the Superior Proposal. In determining whether to make a Change of Recommendation in response to a Superior Proposal or otherwise, the board of directors of the Company shall take into account any changes to the terms of this Agreement proposed by Parent and any other information provided by Parent in response to such notice. During the three (3) business day period referenced in this clause (c), the Company agrees, if requested by Parent, to negotiate in good faith with Parent with respect to any revisions to the terms of the transaction contemplated by this Agreement proposed by Parent. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.2(c), including with respect to the notice period referred to in this Section 6.2(c).

-45-

(d) Certain Permitted Disclosure. Nothing contained in this Section 6.2 shall be deemed to prohibit the Company from complying with its disclosure obligations under U.S. federal or state Law with regard to an Acquisition Proposal or otherwise; provided, however, that if such disclosure does not reaffirm the Company Recommendation or has the substantive effect of withdrawing or adversely modifying the Company Recommendation, such disclosure shall be deemed to be a Change of Recommendation and Parent shall have the right to terminate this Agreement as set forth in Section 8.4; provided, however, that it is understood and agreed that a factually accurate public statement by the Company concerning financial results, operations or business conditions or developments, or that describes the Company's receipt of an Acquisition Proposal and the operation of this Agreement with respect thereto, or any "stop, look and listen" communication by the board of directors of the Company pursuant to Rule 14d-9(f) of the Exchange Act, or any similar communication to the stockholders of the Company, shall not constitute a Change of Recommendation.

(e) Existing Discussions. The Company agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposal. The Company agrees that it will take the necessary steps to promptly inform the individuals or entities referred to in the first sentence hereof of the obligations undertaken in this Section 6.2 and in the Confidentiality Agreement. The Company also agrees that it will promptly request each Person that has heretofore executed a confidentiality agreement in connection with its consideration of acquiring it or any of its Subsidiaries to return all confidential information heretofore furnished to such Person by or on behalf of it or any of its Subsidiaries.

(f) Notice. The Company agrees that it will promptly (and, in any event, within 24 hours) notify Parent if any inquiries, proposals or offers with respect to an Acquisition Proposal are received by, any such information is requested from, or any such discussions or negotiation are sought to be initiated or continued with, it or any of its Representatives indicating, in connection with such notice, the name of such Person and the material terms and conditions of any proposals or offers (including, if applicable, copies of any written requests, proposals or offers, including proposed agreements, financing commitments, and written summaries of any material terms not made in writing) and thereafter shall keep Parent reasonably informed, on a current basis, of the status and terms of any such proposals or offers (including any amendments thereto) and the status of any such discussions or negotiations, including any change in the Company's intentions as previously notified.

6.3. Proxy Filing; Information Supplied. The Company shall prepare and file with the SEC, as promptly as reasonably practicable after the date of this Agreement, and in any event within 15 days after the date of this Agreement, a proxy statement in preliminary form relating to the Stockholders Meeting (as defined in

-46-

Section 6.4) (such proxy statement, including any amendment or supplement thereto, the "Proxy Statement"). The Company agrees, as to itself and its Subsidiaries, that (a) the Proxy Statement will comply as to form in all material respects with the applicable provisions of the Exchange Act and the rules and regulations thereunder and (b) none of the information supplied by it or any of its Subsidiaries for inclusion or incorporation by reference in the Proxy Statement will, at the date of mailing to stockholders of the Company or at the time of the Stockholders Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

6.4. Stockholders Meeting. The Company will take, in accordance with applicable Law and its certificate of incorporation and by-laws, all action necessary to convene a meeting of holders of Shares (the "Stockholders Meeting") as promptly as reasonably practicable after the execution of this Agreement, to consider and vote upon the adoption of this Agreement, and shall not postpone or adjourn such meeting except to the extent required by Law or if at the time for which the Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Stockholders Meeting or to provide the Requisite Company Vote or as may be reasonably necessary to solicit the adoption of this Agreement by the holders of Shares. Subject to Section 6.2(a) hereof, the board of directors of the Company shall recommend such adoption and shall take all lawful action to solicit such adoption of this Agreement. In the event that subsequent to the date hereof, the board of directors of the Company determines that this Agreement is no longer advisable and makes a Change of Recommendation, the Company shall nevertheless submit this Agreement to the holders of the Shares for adoption at the Stockholders Meeting unless this Agreement shall have been terminated in accordance with its terms prior to the Stockholders Meeting.

6.5. Filings; Other Actions; Notification. (a) Proxy Statement. The Company shall promptly notify Parent of the receipt of all comments of the SEC with respect to the Proxy Statement and of any request by the SEC for any amendment or supplement thereto or for additional information and shall promptly provide to Parent copies of all correspondence between the Company and/or any of its Representatives and the SEC with respect to the Proxy Statement. The Company and Parent shall each use its reasonable best efforts to promptly provide responses to the SEC with respect to all comments received on the Proxy Statement by the SEC, and the Company shall cause the definitive Proxy Statement to be mailed as promptly as reasonably practicable after the date the SEC staff advises that it has no further comments thereon or that the Company may commence mailing the Proxy Statement.

(b) Cooperation. Subject to the terms and conditions set forth in this Agreement, the Company and Parent shall cooperate with each other and use (and shall cause their respective Subsidiaries to use) their respective reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under this Agreement and applicable Laws to

consummate and make effective the Merger and the other transactions contemplated by this Agreement as soon as practicable, including preparing and filing as promptly as practicable all documentation to effect all necessary notices, reports and other filings and to obtain as promptly as practicable all consents, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any third party and/or any Governmental Entity in order to consummate the Merger or any of the other transactions contemplated by this Agreement. Notwithstanding the foregoing, nothing in this Agreement, including this clause (b), shall require, or be construed to require, Parent to proffer to, or agree to, sell, divest, lease, license, transfer, dispose of or otherwise encumber or hold separate and agree to sell, divest, lease, license, transfer, dispose of or otherwise encumber before or after the Effective Time, any assets, licenses, operations, rights, product lines, businesses or interest therein of Parent, the Company or any of their respective Affiliates (or to consent to any sale, divestiture, lease, license, transfer, disposition or other encumberment by the Company of any of its assets, licenses, operations, rights, product lines, businesses or interest therein or to any agreement by the Company to take any of the foregoing actions) or to agree to any changes (including through a licensing arrangement) or restriction on, or other impairment of Parent's ability to own or operate, any such assets, licenses, operations, rights, product lines, businesses or interests therein or Parent's ability to vote, transfer, receive dividends or otherwise exercise full ownership rights with respect to the stock of the Surviving Company (any of the foregoing, "Detriments"); provided, however, that Parent's "reasonable best efforts" obligation shall require Parent to (i) sell, license or otherwise dispose of (or agree to sell, license or otherwise dispose of), businesses or assets of either Parent, the Company or their Subsidiaries that in the aggregate produced net revenues in an amount not in excess of $325,000,000 for Parent, the Company and their respective Subsidiaries during the 2011 fiscal year calculated in accordance with GAAP, on a basis consistent with the accounting principles used in preparing their respective 2011 audited financial statements as filed with the SEC (provided that (x) in the case of businesses or assets that were acquired during the 2011 fiscal year, the net revenues with respect to the business or assets that were so acquired shall include the net revenues produced by the transferee in the 2011 fiscal year prior to such acquisition, (y) with respect to a product that was introduced in the 2011 fiscal year or the 2012 fiscal year, aggregate produced net revenues for purposes of this calculation shall mean such amounts projected in the most recent regularly prepared budget for the first fiscal year following the year in which the product launches and (z) in the case of businesses or assets that were acquired during the 2012 fiscal year, the net revenues with respect to the businesses or assets that were so acquired shall include net revenues for the 2011 calendar year as reflected on the most recent regularly prepared audited financial statements of the transferee, calculated in accordance with GAAP) (the "Detriments Limit") and (ii) sell or otherwise dispose of businesses or assets that Parent or any Subsidiary of Parent agrees to acquire after the date of this Agreement, without regard to the Detriments Limit, and such sale or disposal shall not be included in the calculation of the Detriments Limit, in each case if such action should be reasonably necessary to (x) obtain any consent or approval required for the consummation of the Merger under Section 7.1(b) or (y) eliminate, terminate or remove the issuance of any Order described in Section 7.1(c), to the extent related to antitrust or competition matters, in each case prior to March 4, 2013 (if the Termination

-48-

Date is not extended as provided in Section 8.2) or June 3, 2013 (if the Termination Date is so extended). Notwithstanding the foregoing, however, Parent shall not be required to agree to any such dispositions (and shall be entitled in good faith to contest any threatened or pending litigation or proceeding brought by any Governmental Entity) unless failure to do so would result in the closing conditions not being met hereunder prior to the earlier of (1) the termination of this Agreement and (2) March 4, 2013 (if the Termination Date is not extended as provided in Section 8.2) or June 3, 2013 (if the Termination Date is so extended). If requested by Parent, the Company will agree to any action contemplated by this Section 6.5(b), provided that such agreement or action is conditioned on the consummation of the Merger. In furtherance and not in limitation of the foregoing, each party hereto agrees to make any appropriate filings, if necessary or advisable, pursuant to the HSR Act or other applicable foreign, federal, state or supranational antitrust, competition, fair trade or similar Laws with respect to the Merger as promptly as practicable and in any event within ten (10) business days of the date hereof (unless otherwise mutually agreed between the parties). The Company and Parent will each request early termination of the waiting period with respect to the Merger under the HSR Act. Subject to applicable Laws relating to the exchange of information and subject to the limitations and conditions set forth herein, (x) Parent and the Company shall jointly direct all matters with any Governmental Entity consistent with their obligations hereunder (with Parent's legal counsel taking the lead in such matters); provided, that to the extent Parent and the Company are unable to come to agreement on such matters, the respective Chief Executive Officers of the Company and Parent Holdco shall work in good faith to resolve such matters (it being understood that in the event the two Chief Executive Officers are unable to come to agreement, Parent shall have the right to make the determination (acting in good faith) with respect to such disputed matter) and (y) Parent and the Company shall each have the right to review in advance and, to the extent practicable, each will consult with the other on and consider in good faith the views of the other in connection with, all of the information relating to Parent or the Company, as the case may be, and any of their respective Subsidiaries, that appears in any filing made with, or written materials submitted to, any third party and/or any Governmental Entity in connection with the Merger and the other transactions contemplated by this Agreement (including the Proxy Statement). In exercising the foregoing rights, each of the Company and Parent shall act reasonably and as promptly as practicable.

(c) Information. Subject to the Laws relating to the exchange of information, the Company and Parent each shall, upon request by the other, furnish the other with all information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with the Proxy Statement or any other statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any third party and/or any Governmental Entity in connection with the Merger and the transactions contemplated by this Agreement; provided, however, that the Company shall not be obligated to provide such information if the Company determines, in its reasonable judgment, that doing so would (i) violate applicable Law, (ii) violate a Contract or obligation of confidentiality owing to a third party if the Company shall have used

-49-

commercially reasonable efforts to obtain the consent of such third party to such disclosure, or (iii) jeopardize the protection of an attorney-client privilege. Until the Effective Time, the information provided will be subject to the terms of the Confidentiality Agreement, dated as of July 14, 2011, as amended on February 27, 2012 and August 27, 2012, by and between Parent and the Company (as it may be amended from time to time, the "Confidentiality Agreement").

(d) Status. Subject to applicable Laws and as required by any Governmental Entity, the Company and Parent each shall keep the other apprised of the status of matters relating to completion of the transactions contemplated hereby, including promptly furnishing the other with copies of notices or other communications received by Parent or the Company, as the case may be, or any of its Subsidiaries, from any third party and/or any Governmental Entity with respect to the Merger and the other transactions contemplated by this Agreement. The Company shall give prompt notice to Parent of any change, fact or condition that is reasonably expected to result in a Company Material Adverse Effect or of any failure of any condition to Parent's obligations to effect the Merger; provided, however, that the Company's failure to comply with the foregoing shall not give rise to a termination right by Parent pursuant to Section 8.4(d). The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of (i) any notice or other communication received by such party from any Governmental Entity in connection with the Merger or from any Person alleging that the consent of such Person is or may be required in connection with the Merger, if the subject matter of such communication or the failure of such party to obtain such consent could be material to the Company, the Surviving Corporation or Parent and (ii) any actions, suits, claims, investigations or proceedings commenced or, to such party's knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries which relate to the Merger. Neither the Company nor Parent shall permit any of its officers or any other representatives or agents to participate in any in-person meeting with any Governmental Entity in respect of any filing, investigation or other inquiry relating to the transactions contemplated hereby unless it consults with the other party in advance. The Company shall not initiate any offer to any Government Entity with respect to any proposed Detriment.

6.6. Access and Reports. Subject to applicable Law, upon reasonable notice, the Company shall (and shall cause its Subsidiaries to) afford Parent's officers and other authorized Representatives reasonable access, during normal business hours throughout the period prior to the Effective Time, to its employees, properties, books, contracts and records (provided that Parent and its Representatives shall not conduct any activities in such a manner as to interfere unreasonably with the business or operations of the Company) and, during such period, the Company shall (and shall cause its Subsidiaries to) furnish promptly to Parent all information concerning its business, properties and personnel as may reasonably be requested, provided that no investigation pursuant to this Section 6.6 shall affect or be deemed to modify any representation or warranty made by the Company herein, and provided, further, that the foregoing shall not require the Company (i) to permit any inspection, or to disclose any information, that in

-50-

the reasonable judgment of the Company would result in the disclosure of any trade secrets of third parties or violate any of its obligations with respect to confidentiality if the Company shall have used reasonable best efforts to obtain the consent of such third party to such inspection or disclosure or (ii) to disclose any privileged information of the Company or any of its Subsidiaries. All requests for information made pursuant to this Section 6.6 shall be directed to the executive officer or other Person designated by the Company. All such information shall be governed by the terms of the Confidentiality Agreement.

6.7. Stock Exchange Delisting. Prior to the Closing Date, the Company shall cooperate with Parent and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of the NYSE to enable the delisting by the Surviving Corporation of the Shares from the NYSE and the deregistration of the Shares under the Exchange Act as promptly as practicable after the Effective Time, and in any event no more than ten (10) days after the Closing Date.

6.8. Publicity. The initial press release regarding the Merger shall be a joint press release to be reasonably agreed upon by Parent and the Company and thereafter the Company and Parent each shall consult with each other prior to issuing any press releases or otherwise making public announcements with respect to the Merger and the other transactions contemplated by this Agreement and prior to making any filings with any third party and/or any Governmental Entity (including any national securities exchange or interdealer quotation service) with respect thereto, except as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange or interdealer quotation service or by the request of any Governmental Entity and except for any public announcement contemplated by Section 6.2(d). Each of Parent and the Company may make any public statement in response to specific questions by the press, analysts, investors or those attending industry conferences or financial analyst conference calls, so long as such statements are substantially similar to previous press releases, public disclosures or public statements made by Parent and the Company. For the avoidance of doubt, the Company will no longer be required to obtain any prior consent of, or consult with, Parent in connection with any such press release or public announcement if the Company's board of directors has effected any Change of Recommendation or shall have resolved to do so.

6.9. Employee Benefits. (a) Parent agrees that, during a period of twelve (12) months immediately following the Closing Date, the employees of the Company and its Subsidiaries who remain employed following the Effective Time (the "Continuing Employees") will be provided with the retention bonuses, benefits and severance benefits set forth on Schedule 6.9(a).

(b) With respect to any employee benefit plans in which any Continuing Employee first becomes eligible to participate on or after the Effective Time (any such plans, the "New Plans"), the Surviving Corporation shall use commercially reasonable efforts to (i) waive all preexisting conditions, actively at work requirements,

-51-

exclusion and waiting periods with respect to participation and coverage requirements under the New Plans to the extent they were inapplicable to, or were satisfied under, the Benefit Plans, (ii) recognize service of the Continuing Employees prior to the Effective Time which was credited under the Benefit Plans for purposes of eligibility and vesting (but not benefit accrual) under the New Plans to the same extent such service was credited under the Benefit Plans (except to the extent it would result in a duplication of benefits), as if such service were with the Surviving Corporation, and (iii) cause any eligible expenses incurred by any Continuing Employee and his or her covered dependents under the Benefit Plans during the portion of the plan year ending on the date such Continuing Employee's participation in the corresponding New Plan benefits to be taken into account under such plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in connection with such New Plan.

(c) Prior to the Effective Time, if requested by Parent in writing, to the extent permitted by applicable Law and the terms of the applicable plan or arrangement, the Company shall (i) cause to be amended the Benefit Plans to the extent necessary to provide that no employees of Parent and its Subsidiaries shall commence participation therein following the Effective Time unless the Surviving Corporation or such Subsidiary explicitly authorizes such participation and (ii) cause the Medicis Pharmaceutical Corporation 401(k) Plan to be terminated effective three (3) days prior to the Effective Time.

(d) All formal written communications to the directors, officers or employees of the Company and any of its Subsidiaries pertaining to compensation or benefit matters that are affected by the transactions contemplated by this Agreement shall be subject to Parent's prior consent (not to be unreasonably withheld or delayed). The Company shall provide Parent with a reasonable period of time to review and comment on each such communication (not to be unreasonably withheld or delayed). Any formal group oral presentations with respect to the above shall be materially consistent with such formal written communications.

(e) Notwithstanding the foregoing, nothing contained herein shall (i) be construed as an amendment to any Benefit Plan, (ii) otherwise obligate Parent, the Company or any of their Affiliates to maintain any particular Benefit Plan, (iii) otherwise obligate Parent, the Company or any of their Affiliates to retain the employment of any particular Continuing Employee following the Effective Time or (iv) give any third party the right to enforce any of the provisions of this Section 6.9.

6.10. Expenses. Except as otherwise provided in Section 8.5, whether or not the Merger is consummated, all costs and expenses incurred in connection with the negotiation and effectuation of the terms of this Agreement and the Merger and the other transactions contemplated by this Agreement shall be paid by the party incurring such expense. Notwithstanding anything to the contrary contained herein, except as provided in Section 4.2(b), Parent shall be responsible for and shall pay the amount of any (a)

-52-

documentary, sales, use, real property transfer, real property gains, registration, value-added, transfer, stamp, recording and other similar Taxes ("Transfer Taxes") imposed on Parent, the Company or any of its Subsidiaries in connection with this Agreement and the transactions contemplated hereby and (b) any Transfer Taxes imposed on the stockholders of the Company in connection with this Agreement and the transactions contemplated hereby in respect of assets that are owned directly or indirectly by the Company or any of its Subsidiaries.

6.11. Indemnification; Directors' and Officers' Insurance. (a) From and after the Effective Time, each of Parent and the Surviving Corporation agrees that it will indemnify and hold harmless each present and former director and officer of the Company or any of its Subsidiaries (in each case, when acting in such capacity), determined as of the Effective Time (the "Indemnified Parties"), against any costs or expenses (including in connection with enforcing the indemnity and other obligations referred to in this Section 6.11 and including reasonable attorneys' fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent that the Company would have been permitted under Delaware Law and its certificate of incorporation or by-laws in effect on the date of this Agreement to indemnify such Person (and Parent or the Surviving Corporation shall also advance expenses as incurred to the fullest extent permitted under applicable Law; provided that the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification); and provided, further, that any determination required to be made with respect to whether an Indemnified Party's conduct complies with the standards set forth under Delaware Law and the Company's certificate of incorporation and by-laws shall be made by independent counsel selected by the Surviving Corporation.

(b) Any Indemnified Party wishing to claim indemnification under paragraph (a) of this Section 6.11, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Parent thereof, but the failure to so notify shall not relieve Parent or the Surviving Corporation of any liability it may have to such Indemnified Party except to the extent such failure materially prejudices the indemnifying party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) Parent or the Surviving Corporation shall have the right to assume the defense thereof and Parent and the Surviving Corporation shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if Parent or the Surviving Corporation elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise conflicts of interest between Parent or the Surviving Corporation and the Indemnified Parties, the Indemnified Parties may retain counsel satisfactory to them, and Parent or the Surviving Corporation shall pay all reasonable fees and expenses of such counsel for the Indemnified Parties promptly as

-53-

statements therefor are received; provided, however, that Parent and the Surviving Corporation shall be obligated pursuant to this paragraph (b) to pay for only one firm of counsel for all Indemnified Parties in any jurisdiction unless the use of one counsel for such Indemnified Parties would present such counsel with a conflict of interest, provided that the fewest number of counsels necessary to avoid conflicts of interest shall be used; (ii) the Indemnified Parties will cooperate in the defense of any such matter, and (iii) Parent and the Surviving Corporation shall not be liable for any settlement effected without their prior written consent; and provided, further, that Parent and the Surviving Corporation shall not have any obligation hereunder to any Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law.

(c) Prior to the Effective Time, the Company shall and, if the Company is unable to, Parent shall cause the Surviving Corporation as of the Effective Time to obtain and fully pay for "tail" insurance policies (providing only for the Side A coverage for Indemnified Parties where the existing policies also include Side B coverage for the Company) with a claims period of at least six years from and after the Effective Time from an insurance carrier with the same or better credit rating as the Company's current insurance carrier with respect to directors' and officers' liability insurance and fiduciary liability insurance (collectively, "D&O Insurance") with benefits and levels of coverage at least as favorable as the Company's existing policies with respect to matters existing or occurring at or prior to the Effective Time (including in connection with this Agreement or the transactions or actions contemplated hereby); provided, however, that in no event shall the Company expend for such policies a premium amount in excess of the amount set forth in Section 6.11(c) of the Company Disclosure Schedule. If the Company and the Surviving Corporation for any reason fail to obtain such "tail" insurance policies as of the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, continue to maintain in effect for a period of at least six years from and after the Effective Time the D&O Insurance in place as of the date of this Agreement with benefits and levels of coverage at least as favorable as provided in the Company's existing policies as of the date of this Agreement, or the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, use reasonable best efforts to purchase comparable D&O Insurance for such six-year period with benefits and levels of coverage at least as favorable as provided in the Company's existing policies as of the date of this Agreement; provided, however, that in no event shall Parent or the Surviving Corporation be required to expend for such policies an aggregate premium amount in excess of 300% of the annual premiums currently paid by the Company for such insurance; and, provided further that if the aggregate premiums of such insurance coverage exceed such amount, the Surviving Corporation shall obtain a policy with the greatest coverage available for a cost not exceeding such amount.

(d) If Parent or the Surviving Corporation or any of their respective successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and

-54-

assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Corporation shall assume all of the obligations set forth in this Section 6.11.

(e) The provisions of this Section 6.11 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and his or her heirs or representatives.

(f) The rights of the Indemnified Parties under this Section 6.11 shall be in addition to any rights such Indemnified Parties may have under the certificate of incorporation or by-laws of the Company or any of its Subsidiaries, or under any applicable Contracts or Laws.

(g) The obligations of Parent and the Surviving Corporation under this Section 6.11 shall not be terminated or modified in such a manner as to adversely affect the rights of any Indemnified Party to whom this Section 6.11 applies unless (i) such termination or modification is required by applicable Law or (ii) the affected Indemnified Party shall have consented in writing to such termination or modification (it being expressly agreed that the Indemnified Party to whom this Section 6.11 applies shall be a third party beneficiary of this Section 6.11).

Prior to the Effective Time, the Company and Parent shall take all necessary action to execute and deliver a supplemental indenture to the Trustee (as defined in each of the indentures under which the Convertible Senior Notes were issued (the "Indentures") to each Indenture to provide, among other things, that on and after the Effective Time, each holder of Convertible Senior Notes shall have the right to convert such Convertible Senior Notes into the conversion consideration determined by reference to the consideration receivable upon consummation of the Merger in respect of each Share in accordance with, and subject to, the provisions of the respective Indentures governing the conversions of the Convertible Senior Notes issued thereunder (including any applicable increase in the "Conversion Rate" or decrease in the "Conversion Price" thereunder in connection with the Merger). Prior to the Effective Time, the Company shall take good faith commercially reasonable efforts (a) to take all such actions as may be required in accordance with, and subject to, the terms of the applicable Convertible Senior Notes Indenture, including the giving of any notices that may be required in connection with any repurchases or conversions of the 1.375% Convertible Senior Notes occurring as a result of the transactions contemplated by this Agreement constituting a "Fundamental Change" and/or "Make-Whole Fundamental Change" as such terms are defined in the 1.375% Convertible Senior Notes Indenture, and delivery of any supplemental indentures, legal opinions, officers' certificates or other documents or instruments required in connection with the consummation of the Merger and (b) to facilitate the settlement of the Convertible Note Hedge Obligations and Warrants as reasonably requested by Parent (it being understood that any such settlement will be subject to the respective terms of the Convertible Note Hedge Obligations and Warrants, as such terms may be amended or modified from time to time with the prior written consent of Parent).

Without the Company's prior written consent (which shall not be unreasonably conditioned, withheld or delayed), Parent shall not agree to or permit any amendment, replacement, reduction, supplement, or other modification of, or waive any of its material rights under, the Debt Commitment Letter, if such amendment, replacement, supplement or other modification or waiver would reasonably be expected to prevent, materially delay, or materially impede the consummation of the Debt Financing (or would add any material additional conditions to the availability of the Debt Financing or any replacement financing); provided that, for the avoidance of doubt, Parent may (without the prior consent of the Company) replace and amend the Debt Commitment Letter to add lenders, lead arrangers, book runners, syndication agents, or similar entities that had not executed the Debt Commitment Letter as of the date of this Agreement or to reflect changes to the Debt Commitment Letter made pursuant to the terms set forth in the Fee Letter (as defined in the Debt Commitment Letter). Neither Parent nor Merger Sub shall consent to any assignment or rights or obligations under the Debt Commitment Letter (I) without the prior written approval of the Company, such approval not to be unreasonably withheld or (II) except for assignments under the terms of the Debt Commitment Letter. Parent and Merger Sub shall consult with and keep the Company reasonably informed of the status of their efforts to arrange the Debt Financing and the Bond Financing.

(b) Without limiting Parent's other obligations under this Section 6.15, if the Marketing Period shall not have been completed by April 3, 2013, then unless the Bond Financing or Debt Financing shall have been previously consummated, Parent shall use its commercially reasonable efforts, including through the payment of commercially reasonable fees, to obtain an amendment to the Debt Commitment Letter on or prior to April 3, 2013 to provide that the "outside date" of "March 4, 2013, subject to one extension to June 3, 2013 to the extent that the Termination Date (as defined in the Acquisition Agreement on the date of this Commitment Letter) is extended to June 3, 2013 in accordance with the terms of the Acquisition Agreement" as set forth in the Debt Commitment Letter may be further extended, in the event that the Marketing Period shall have begun but not been completed by the Termination Date, by a number of days equal to the lesser of (i) twenty (20) days plus four (4) business days following the Termination Date and (ii) the number of days then remaining in the Market Period plus four (4) business days (such extended date, the "Extension Date").

Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 9.3 without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto.

Any purported assignment in violation of this Agreement is void.
