EFFECT OF THE MERGER ON CAPITAL STOCK; EXCHANGE OF CERTIFICATES

Section 3.1 Effect on Securities. At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Acquisition Sub or the holders of any securities of the Company or Acquisition Sub:

(a) Cancellation of Treasury Stock and Buyer-Owned Stock. Each share of common stock of the Company, par value $0.02 per share, including the associated Company Rights (as defined herein) (the “Company Common Stock”), owned by the Company or any of its wholly-owned subsidiaries or held by Buyer or any of its wholly-owned subsidiaries immediately prior to the Effective Time shall automatically be cancelled, retired and shall cease to exist, and no consideration or payment shall be delivered in exchange therefor or in respect thereof.

(b) Conversion of Company Securities.

(i) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares cancelled pursuant to Section 3.1(a) hereof and Dissenting Shares) shall be converted into the right to receive the Merger Consideration, in cash, without interest. As of the date hereof, prior to any adjustments pursuant to Section 3.1(c), and without giving effect to (i) any change in the number of outstanding Company Common Stock, Restricted Stock Units or Company Options, and (ii) the equitable adjustment to the exercise prices of the

Company Options or the number of outstanding Company Options and Restricted Stock Units, in each case that will be effected in connection with the Spin-Off pursuant to Article V of the Employee Matters Agreement (the “Equity Adjustment”), the Merger Consideration would be equal to $15.02 per share of Company Common Stock. “Merger Consideration” shall mean the quotient obtained by dividing (a) the sum of (i) the Aggregate Purchase Price and (ii) product of (1) the weighted average exercise price for all In-the-Money Options immediately following the Equity Adjustment (the “Equity Adjustment Date”), multiplied by (2) the aggregate number of shares of Company Common Stock into which all In-the-Money Options are convertible as of the Equity Adjustment Date, by (b) the result of subtracting (i) the number of shares of Company Common Stock into which all Out-of-the-Money Options would be convertible as of the Equity Adjustment Date from (ii) the aggregate number of shares of Company Common Stock on a fully diluted basis (including all Company Options and Restricted Stock Units) as of the Equity Adjustment Date. “Aggregate Purchase Price” shall mean $360,000,000 (three hundred and sixty million dollars), as may be adjusted by application of Section 3.1(c).

(ii) Each share of Company Common Stock to be converted into the right to receive the applicable Merger Consideration pursuant to Section 3.1(b)(i) shall be automatically cancelled and shall cease to exist and the holders of certificates (the “Certificates”) or book-entry shares (“Book-Entry Shares”) that immediately prior to the Effective Time represented such Company Common Stock shall cease to have any rights with respect to such Company Common Stock other than the right to receive, upon surrender of such Certificates or Book-Entry Shares in accordance with Section 3.2 of this Agreement, the Merger Consideration, without interest thereon.

(i) As soon as practicable prior to the Effective Time, but in any event at least 14 days prior to the Stockholders’ Meeting, the Company shall provide Buyer with a schedule setting forth the determination of the CPEX Value, which determination shall be final and binding on the Company and Buyer for purposes of this Agreement.

(ii) The Aggregate Purchase Price shall be reduced by the sum of (A) the product of (i) the excess, if any, of (x) the CPEX Value over (y) the sum of (1) $65,000,000 and (2) the amount determined under clause (B) below, and (ii) the applicable Tax rate(s) as would be imposed by Section 11(b)(1) of the Code assuming no taxable income other than the excess determined under clause (A)(i) above, and (B) the product of (i) the excess, if any, of (x) the CPEX Value over (y) $34,000,000 and (ii) 8.5%.

(d) Conversion of Acquisition Sub Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of common stock, par value of $0.01 per share, of Acquisition Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one (1) fully paid share of common stock, par value $0.01 per share, of the Surviving Corporation and constitute the only outstanding shares of capital stock of the Surviving Corporation.

(e) Adjustments. Without limiting the other provisions of this Agreement, if at any time during the period between the date of this Agreement and the Effective Time, any change in the number of outstanding shares of Company Common Stock shall occur as a result of a reclassification, recapitalization, stock split (including a reverse stock split), or combination, exchange or readjustment of shares, or any stock dividend or stock distribution with a record date during such period, in each case, other than pursuant to the Spin-Off, the applicable Merger Consideration as provided in Section 3.1(b) shall be equitably adjusted to reflect such change.

Section 3.2 Exchange of Company Common Stock.

(a) Designation of Paying Agent; Deposit of Exchange Fund. Prior to the Effective Time, Buyer shall designate a paying agent (the “Paying Agent”) reasonably acceptable to the Company for the payment of the applicable Merger Consideration as provided in Section 3.1(b)(i). At or prior to the Effective Time, Buyer shall deposit, or cause to be deposited with the Paying Agent for the benefit of holders of shares of Company Common Stock, cash constituting an amount equal to the Merger Consideration (such Merger Consideration as deposited with the Paying Agent, the “Exchange Fund”). The Exchange Fund shall not be used for any purpose that is not expressly provided for in this Agreement.

(b) As promptly as practicable following Effective Time, the Surviving Corporation shall cause the Paying Agent to mail (and to make available for collection by hand) to each holder of record of a Certificate or Book-Entry Share, which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (x) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares, as applicable, shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof) or Book-Entry Shares to the Paying Agent and which shall be in the form and have such other provisions as Buyer and the Company may reasonably specify and (y) instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the applicable Merger Consideration into which the number of shares of Company Common Stock previously represented by such Certificate or Book-Entry Shares shall have been converted pursuant to this Agreement (which instructions shall provide that at the election of the surrendering holder, Certificates or Book-Entry Shares may be surrendered, and the applicable Merger Consideration in exchange therefor collected, by hand delivery).

(c) After the Effective Time, upon surrender of a Certificate (or affidavit of loss in lieu thereof) or Book-Entry Share for cancellation to the Paying Agent, together with a letter of transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the applicable Merger Consideration for each share of Company Common Stock formerly represented by such Certificate or Book-Entry Share, to be mailed (or made available for collection by hand if so elected by the surrendering holder) as soon as reasonably practicable, after which the Certificate (or affidavit of loss in lieu thereof) or Book-Entry Share so

surrendered shall be forthwith cancelled. The Paying Agent shall accept such Certificates (or affidavits of loss in lieu thereof) or Book-Entry Shares upon compliance with such reasonable terms and conditions as the Paying Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. No interest shall be paid or accrued for the benefit of holders of the Certificates or Book-Entry Shares on the applicable Merger Consideration (or the cash pursuant to Section 3.2(d)) payable upon the surrender of the Certificates or Book-Entry Shares.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of the Certificates or Book-Entry Shares for twelve (12) months after the Effective Time shall be delivered to Buyer (or its designee), upon demand, and any such holders prior to the Merger who have not theretofore complied with this Article III shall thereafter look only to Buyer (subject to abandoned property, escheat or other similar laws), as general creditors thereof for payment of their claim for cash, without interest, to which such holders may be entitled.

(e) No Liability. None of Buyer, Acquisition Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any person in respect of any cash held in the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificates or Book-Entry Shares shall not have been surrendered prior to one year after the Effective Time (or immediately prior to such earlier date on which any cash in respect of such Certificate or Book-Entry Share would otherwise escheat to or become the property of any Governmental Authority), any such cash in respect of such Certificate or Book-Entry Share shall, to the extent permitted by applicable Law, become the property of Buyer, free and clear of all claims or interest of any person previously entitled thereto.

(f) Investment of Exchange Fund. The Paying Agent shall invest the cash included in the Exchange Fund as directed by Buyer or, after the Effective Time, the Surviving Corporation in (i) direct obligations of the United States of America, (ii) obligations for which the full faith and credit of the United States of America is pledged to provide for payment of all principal and interest, or (iii) commercial paper obligations receiving the highest rating from either ▇▇▇▇▇’▇ Investor Services, Inc. or Standard & Poor’s, a division of The McGraw Hill Companies, or a combination thereof. Any interest and other income resulting from such investments shall be paid to and be income of Buyer. If for any reason (including losses) the cash in the Exchange Fund shall be insufficient to fully satisfy all of the payment obligations to be made in cash by the Paying Agent hereunder, Buyer shall promptly deposit cash into the Exchange Fund in an amount which is equal to the deficiency in the amount of cash required to fully satisfy such cash payment obligations.

Section 3.3 Stock Options and Restricted Stock Units.

(a) Treatment of Options. Each Company Option outstanding immediately prior to the Effective Time, whether vested or unvested, shall, by virtue of the Merger and without any action on the part of any holder of any Company Option, become fully vested and be cancelled and converted into the right to receive at the Effective Time, as promptly as reasonably practicable following the Effective Time, a cash payment with respect thereto equal to the

product of (a) the excess, if any, of the Merger Consideration over the exercise price per share of such Company Option multiplied by (b) the number of shares of Company Common Stock issuable upon exercise of such Company Option (the “Option Cash Payment”), less any applicable withholding taxes. If the applicable exercise price of any Company Option equals or exceeds the Merger Consideration, such Company Option shall be cancelled at the Effective Time without payment of consideration, and all rights with respect to such Company Option shall terminate as of the Effective Time. As of the Effective Time, all Company Options shall no longer be outstanding and shall automatically cease to exist, and each holder of a Company Option shall cease to have any rights with respect thereto, except the right to receive the Option Cash Payment, if any.

(b) Treatment of Restricted Stock Units. As of the Effective Time, each Restricted Stock Unit that is issued and outstanding immediately prior to the Effective Time, shall, by virtue of the Merger and without any action on the part of any holder of any Restricted Stock Unit, become fully vested and be cancelled and converted into the right to receive at the Effective Time, as promptly as reasonably practicable following the Effective Time, a cash payment with respect thereto equal to the Merger Consideration (the “Restricted Stock Unit Payment”), less any applicable withholding taxes. As of the Effective Time, all Restricted Stock Units shall no longer be outstanding and shall automatically cease to exist, and each holder of a Restricted Stock Unit shall cease to have any rights with respect thereto, except the right to receive the Restricted Stock Unit Payment.

(c) Necessary Action. Prior to the Effective Time, the Company shall take any and all actions necessary to effectuate the provisions of this Section 3.3, including, without limitation, providing holders of Company Options and Restricted Stock Units with notice of their rights with respect to any such Company Options and Restricted Stock Units as provided herein.

Section 3.4 Lost Certificates. If 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 the Surviving Corporation, the posting by such person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration to which the holder thereof is entitled pursuant to this Article III.

Section 3.5 Dissenting Shares. Notwithstanding Section 3.1(b) hereof, to the extent that holders thereof are entitled to appraisal rights under Section 262 of Delaware Law, shares of Company Common Stock issued and outstanding immediately prior to the Effective Time and held by a holder who has properly exercised and perfected his or her demand for appraisal rights under Section 262 of Delaware Law (the “Dissenting Shares”) shall not be converted into the right to receive the applicable Merger Consideration, but, instead, the holders of such Dissenting Shares shall be entitled to receive such consideration as shall be determined pursuant to Section 262 of Delaware Law; provided, however, that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost his or her right to appraisal and payment under Delaware Law, such holder’s shares of Company Common Stock shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the applicable Merger Consideration, without any interest thereon, and such shares shall not be

deemed to be Dissenting Shares. The Company shall give Buyer (i) prompt notice of any demands for appraisal filed pursuant to Section 262 of Delaware Law received by the Company, withdrawals of such demands and any other instruments served or delivered in connection with such demands pursuant to Delaware Law and received by the Company and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands made pursuant to Section 262 of Delaware Law. The Company shall not (x) make any payment with respect to any such demand, (y) offer to settle, settle or approve any withdrawal or other treatment of, any such demand or (z) waive any failure to timely deliver a written demand for appraisal or timely take any other action to perfect appraisal rights in accordance with Delaware Law, except in each case with the prior written consent of Buyer, which consent shall not be unreasonably withheld, delayed or conditioned; provided that no such consent shall be required if such actions are required by Delaware Law or court order. Any payments required to be made with respect to the Dissenting Shares shall be made by Buyer (and not the Company or Acquisition Sub) and the Merger Consideration shall be reduced, on a dollar for dollar basis, as if the holder of such Dissenting Shares had not been a stockholder on the Closing Date.

Section 3.6 Transfers; No Further Ownership Rights. After the Effective Time, there shall be no registration of transfers on the stock transfer books of the Company of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If Certificates are presented to the Surviving Corporation for transfer following the Effective Time, they shall be cancelled against delivery of the applicable Merger Consideration, for each share of Company Common Stock formerly represented by such Certificates.

Section 3.7 Withholding Rights. Buyer, the Surviving Corporation or the Paying Agent, as applicable, shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock, Company Options or Restricted Stock Units, as applicable, such amounts as Buyer, the Surviving Corporation or the Paying Agent, as the case may be, is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and timely paid over to the appropriate taxing authority by Buyer, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock, Company Options or Restricted Stock Units, as applicable.

ARTICLE IV

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as expressly stated, no representations and warranties are being made in this Agreement by the Company with respect to CPEX or the Drug Delivery Business, including by referencing the Company’s subsidiaries, but solely to the extent that the matters relating to CPEX and the Drug Delivery Business that would otherwise be disclosed pursuant to such representations and warranties would not have any adverse impact on the Company after giving effect to the Spin-Off and would not reasonably be expected to prevent or materially delay the consummation of the transactions hereunder. Except as set forth in the disclosure schedule delivered by the Company to Buyer immediately prior to the execution of this Agreement (the

“Company Disclosure Schedule”) (with specific reference to the particular Section or subsection of this Agreement to which the information set forth in such disclosure schedule relates, provided, that the information in any section or paragraph of the Company Disclosure Schedule shall qualify the other Sections and subsections of this Agreement to the extent that the relevance of such information to such other Sections and subsections is reasonably apparent from a reading of such information), the Company represents and warrants to Buyer and Acquisition Sub as follows:

Section 4.1 Organization and Qualification; Subsidiaries.

(a) Each of the Company and its subsidiaries is a corporation or legal entity duly organized or formed, validly existing and in good standing, under the laws of its jurisdiction of organization or formation, and is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction in which the character of the properties owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary, except for such failures to be so qualified or licensed and in good standing as have not had, and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect. Each of the Company and its subsidiaries has the requisite corporate, partnership or limited liability company power and authority, as applicable, except where the failure to have such power and authority has not had, and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

(b) Section 4.1(b) of the Company Disclosure Schedule lists each of the Company’s subsidiaries (excluding CPEX) and, for each such subsidiary, the jurisdiction of incorporation or formation, as the case may be. All of the issued and outstanding shares of capital stock of, or other equity interests in, each such subsidiary of the Company have been validly issued and are fully paid and non-assessable and are owned directly or indirectly by the Company free and clear of all pledges, liens, charges, encumbrances or security interests of any kind or nature whatsoever, and free of any restriction on the right to vote, sell or otherwise dispose of such capital stock or other equity interests.

Section 4.2 Company Certificate and Company By-laws. The Company has made available to Buyer a complete and correct copy of the Certificate of Incorporation and the By-laws (or equivalent organizational documents) of the Company and each of its subsidiaries, each as amended to date. The Company Certificate and the Company By-laws (or equivalent organizational documents) of the Company and each of its subsidiaries are in full force and effect. None of the Company or any of its subsidiaries is in violation of any provision of the Company Certificate or the Company By-laws (or equivalent organizational documents).

Section 4.3 Capitalization.

(a) The authorized capital stock of the Company consists of 100,000,000 shares of Company Common Stock and 2,000,000 shares of the Company’s preferred stock, par value $1.00 per share (the “Company Preferred Stock”). As of the close of business on March 29, 2008 (the “Measurement Date”), (i) 22,495,814 shares of Company Common Stock were outstanding, of which 22,449,814 were issued and 46,000 were contingently issuable; (ii) no shares of Preferred Stock were issued and outstanding; and (iii) 492,452 shares of Company

As of the Measurement Date, there were 54,167 shares of Company Common Stock authorized and reserved for future issuance as matching contributions to the Company 401(k) Plan in lieu of cash contributions. Except as set forth above, as of the Measurement Date, no shares of capital stock of, or other equity or voting interests in, the Company, or options, restricted stock units, warrants or other rights to acquire any such stock or securities were issued, reserved for issuance or outstanding. All outstanding shares of capital stock of the Company are, and all shares that may be issued pursuant to the Company Option Plans or the Company 401(k) Plan will be, when issued in accordance with the terms thereof, duly authorized, validly issued, fully paid and non-assessable and not subject to preemptive rights (either statutory or pursuant to contracts or agreements to which the Company or any of its subsidiaries is a party).

(b) Section 4.3(b) of the Company Disclosure Schedule sets forth, as of the date of this Agreement, a true and complete list of each person in which the Company owns, directly or indirectly, any equity, membership, partnership, limited liability, voting or similar interest, and the percentage ownership of such person.

If at any time prior to the Effective Time any event or circumstance relating to the Company or Buyer or any of either the Company or Buyer’s subsidiaries, or their respective officers or directors, should be discovered by the Company or Buyer, respectively, which, pursuant to the Securities Act or Exchange Act, should be set forth in an amendment or a supplement to the Proxy Statement, such party shall promptly inform the other. Each of Buyer, Acquisition Sub and the Company agree to correct any material information provided by it for use in the Proxy Statement which shall have become false or misleading. All documents (including the Proxy Statement) that each of the Company and Buyer is responsible for filing with the SEC in connection with the Merger will comply as to form in all material respects with the applicable requirements of the Securities Act and the Exchange Act.

Section 6.3 Stockholders’ Meetings. Subject to Section 6.6 hereof, the Company shall, as promptly as reasonably practicable following the date of this Agreement establish a record date for, duly call, give notice of, convene and hold a meeting of its stockholders, for the purpose of voting upon the adoption of this Agreement and approval of the Merger (the “Stockholders’ Meeting”), and the Company shall hold the Stockholders’ Meeting; provided, however, that if the Spin-Off has not been completed prior to the date of the Stockholders’ Meeting, the Company shall be permitted to delay or postpone convening the Stockholders’ Meeting to a date that is 14 days following the completion of the Spin-Off. At such Stockholders’ Meeting, the Company shall, subject to Section 6.6(d) hereof, recommend to its stockholders the adoption of this Agreement and the other transactions contemplated by this Agreement and approval of the Merger (the “Company Recommendation”) and, subject to Section 6.6(d), the Company shall also (i) use all reasonable efforts to solicit or cause to be solicited from its stockholders proxies in favor of adoption of this Agreement and consummation of the Merger and (ii) take all other reasonable action necessary to secure the Requisite Stockholder Approval; provided, however, that the Company shall not be obligated to recommend to its Stockholders the adoption of this Agreement or approval of the Merger at its Stockholders’ Meeting to the extent that the board of directors of the Company makes a Change of Recommendation in accordance with Section 6.6(d).

Section 6.4 Appropriate Action; Consents; Filings; Spin-Off.

(a) The parties hereto will use their respective reasonable best efforts to consummate and make effective the transactions contemplated hereby and to cause the conditions to the Merger set forth in Article VII to be satisfied including (i) the obtaining of all necessary actions or nonactions, consents and approvals from Governmental Authorities or other persons necessary in connection with the consummation of the transactions contemplated by this Agreement and the making of all necessary registrations and filings (including filings with Governmental Authorities if any) and the taking of all reasonable steps as may be necessary to obtain an approval from, or to avoid an action or proceeding by, any Governmental Authority or other persons necessary in connection with the consummation of the transactions contemplated by this Agreement, (ii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions performed or consummated by such party in accordance with the terms of this Agreement, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed, and (iii) the execution and delivery of any additional instruments necessary to consummate the Merger and other transactions to be performed or consummated by such party in accordance with the terms of this Agreement and to fully carry out the purposes of this Agreement. Each of the parties hereto shall, as promptly as practicable, make its respective filings, and thereafter make any other required submissions under the Antitrust Laws with respect to the transactions contemplated hereby.

(b) Buyer and Acquisition Sub agree to use reasonable best efforts to obtain all consents under any antitrust, competition or pharmaceutical Law that may be required by any foreign or U.S. federal, state or local antitrust or competition Governmental Authority, or by the FDA or similar Governmental Authority, in each case with competent jurisdiction, so as to enable the parties to close the transactions contemplated by this Agreement as promptly as practicable, including committing to or effecting, by consent decree, hold separate orders, trust,

or otherwise, as is commercially reasonable, the sale or disposition of such assets or businesses as are required to be divested (the “Divestiture”) to avoid the entry of, or to effect the dissolution of or vacate or lift, any Order, that would otherwise have the effect of preventing or materially delaying the consummation of the Merger and the other transactions contemplated by this Agreement. Buyer shall have the sole and exclusive right, to propose, negotiate, offer to commit and effect, by consent decree, hold separate order or otherwise, the Divestiture of such assets of Buyer, the Company, or their respective subsidiaries or otherwise offer to take or offer to commit (and if such offer is accepted, commit to and effect) to take any action as may be required to avoid the entry of, dissolve, vacate or lift any such Order. Further, and for the avoidance of doubt, Buyer will take any and all commercially reasonable actions necessary in order to ensure that (x) no requirement for any non-action, a consent or approval of any State Attorney General or other Governmental Authority, (y) no decree, judgment, injunction, temporary restraining order or any other order in any suit or proceeding, and (z) no other matter relating to any antitrust or competition Law which would preclude consummation of the Merger by the Termination Date. Notwithstanding the foregoing, in no event shall any of Buyer, Acquisition Sub, the Company or their respective affiliates be required to take or agree to take any such action, that, individually or together with any other such actions, would reasonably be expected to have a material adverse effect on the financial condition, business, assets or results of operations of the Company and its subsidiaries taken as a whole, or an effect of similar magnitude on Buyer and its subsidiaries.

(c) Each of Buyer and the Company shall give (or shall cause its respective subsidiaries to give) any notices to third parties, and Buyer and the Company shall use, and cause each of its subsidiaries to use, its reasonable best efforts to obtain any third party consents not covered by paragraphs (a) and (b) above, necessary, proper or advisable to consummate the Merger. Each of the parties hereto will furnish to the other such necessary information and reasonable assistance as the other may request in connection with the preparation of any required governmental filings or submissions and will cooperate in responding promptly to any inquiry from a Governmental Authority, including promptly informing the other party of such inquiry, consulting in advance before making any presentations or submissions to a Governmental Authority (considering in good faith the views of the other party in any such presentation or submission), supplying each other with copies of all material correspondence, filings or communications between either party and any Governmental Authority with respect to this Agreement.

(d) The Company shall use its reasonable best efforts to complete the Spin-Off as promptly as practicable; provided that nothing in this Section 6.4(d) shall require the board of directors of the Company to take any action that would be inconsistent with its fiduciary duties under applicable Law.

(e) Each of Buyer and Acquisition Sub, on the one hand, and the Company on the other hand, covenants and agrees that between the date hereof and the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, each of Buyer, Acquisition Sub and the Company shall not, and shall not permit any of their respective subsidiaries to, take or agree to take any action that would prevent or materially delay the consummation of the transactions contemplated hereby.

Section 6.5 Access to Information; Confidentiality.

(a) From the date hereof to the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, to the extent permitted by applicable Law, the Company will provide to Buyer (and its officers, directors, employees, accountants, consultants, legal counsel, agents and other representatives, collectively, “Representatives”) reasonable access during normal business hours to the Company’s and its subsidiaries’ properties, books, contracts and records, personnel and other information as Buyer may reasonably request regarding the business, assets, liabilities, employees and other aspects of the Company; provided, however, that the Company shall not be required to provide access to any information or documents which would, in the reasonable judgment of the Company, (i) breach any agreement with any third-party, (ii) constitute a waiver of the attorney-client or other privilege held by the Company, or (iii) otherwise violate any applicable Laws. For the avoidance of doubt, and notwithstanding the foregoing, the Company has not provided, shall not be required to provide, and following the Spin-Off the Company shall not have access to, the properties, books, contracts and records and other information as it relates to the business, assets, liabilities, employees and other aspects of the Drug Delivery Business, and neither the Company nor CPEX shall have any obligation at any time to grant such access to Buyer; provided, however, that the Company shall reasonably cooperate to provide requested information and access with respect to CPEX to the extent reasonably related to the transactions contemplated by this Agreement. The Company shall cause the officers, employees, consultants, agents, accountants, attorneys and other Representatives of the Company and its subsidiaries to reasonably cooperate with Buyer and Buyer’s Representatives in connection with such investigation and examination, and Buyer and its Representatives shall cooperate with the Company and its Representatives and shall use their reasonable efforts to minimize any disruption to the business.

(b) The parties shall comply with, and shall cause their respective Representatives to comply with, all of their respective obligations under the Confidentiality Agreement.

Section 6.6 No Solicitation of Competing Proposal.

(a) From and after the date of this Agreement until the earlier of the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, and except as otherwise provided for in this Agreement (including the other subsections of this Section 6.6), the Company agrees that it shall not, nor shall it authorize or knowingly permit any of its Representatives, or any of its subsidiaries, affiliates or any of their respective Representatives to, directly or indirectly: (i) solicit, initiate or knowingly facilitate or encourage (including by way of providing material nonpublic information), or agree to, approve or endorse, any Competing Proposal, (ii) enter into, continue or otherwise participate in any negotiations regarding, or furnish to any person any material nonpublic information with respect to, any Competing Proposal, (iii) enter into, continue or otherwise engage in discussions with any person with respect to, any Competing Proposal, (iv) approve or recommend any Competing Proposal, (v) enter into any letter of intent or similar document or any agreement or commitment to (x) facilitate or consummate any Competing Proposal, (y) approve or endorse any Competing Proposal, (z) in connection with any Competing Proposal, require it to abandon, terminate or fail to consummate the Merger, (vi) amend or grant any waiver or release or approve any transaction or redeem any Company Rights under the Company Rights Agreement, except in connection with the transactions contemplated by this Agreement, or (vii) resolve, propose or agree to take

any of the actions prohibited by clauses (i) through (vi) of this sentence. The Company shall, and shall cause its Representatives, subsidiaries, affiliates and their respective Representatives to, immediately cease and cause to be terminated all existing solicitations, discussions or negotiations with respect to any person conducted heretofore by the Company, any of its subsidiaries or affiliates or their respective Representatives with respect to any Competing Proposal, and shall demand the return or destruction of any information previously provided with respect to such activities, discussions or negotiations, subject to the restrictions set forth in any applicable confidentiality agreements. Notwithstanding anything to the contrary contained herein, the Company shall be permitted to terminate, amend, modify, waive or fail to enforce any provision of any “standstill” or similar obligation of any person in order that such person may submit a Competing Proposal if the board of directors of the Company determines in good faith after consultation with the Company’s outside legal and financial advisors that failure to take such action would be inconsistent with the directors’ exercise of their fiduciary duties to the Company’s stockholders under applicable Law.

(b) Notwithstanding the limitations set forth in Section 6.6(a), if the Company receives a bona fide written Competing Proposal that the board of directors of the Company determines in good faith after consultation with the Company’s outside legal and financial advisors (i) constitutes a Superior Proposal or (ii) could reasonably be expected to result in a Superior Proposal, the Company may, if its board of directors determines in good faith after consultation with the Company’s outside legal and financial advisors that failure to take such action would be inconsistent with its fiduciary duties under applicable Law, and subject to compliance with Section 6.6(e), take the following actions: (x) furnish nonpublic information with respect to the Company and its subsidiaries to the third party making such Competing Proposal and (y) engage in discussions or negotiations with the third party with respect to the Competing Proposal, in each case if, and only if, (A) all such information has previously been provided to Buyer or is provided to Buyer prior to or substantially concurrent with the time it is provided to such third party and (B) prior thereto, the Company and such third party enter into a confidentiality and standstill with such person that contains confidentiality and standstill provisions that are no less favorable in the aggregate to the Company than those contained in the Confidentiality Agreement (an “Acceptable Confidentiality Agreement”).

(c) Except as set forth in Section 6.6(d), neither the board of directors of the Company nor any committee thereof shall (i)(A) change, qualify, withhold or withdraw, or publicly propose to change, qualify, withhold or withdraw the Company Recommendation or (B) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Competing Proposal (any action described in this clause (i) being referred to as a “Change of Recommendation”) or (ii) approve or recommend, or propose to approve or recommend, or allow the Company or any of its affiliates to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement constituting or related to, any Competing Proposal (other than an Acceptable Confidentiality Agreement referred to in Section 6.6(b)) (each of the documents referred to in this clause (ii) shall be an “Acquisition Agreement”).

(d) Notwithstanding the provisions of Section 6.6(c), if at any time prior to obtaining the Requisite Stockholder Approval, the board of directors of the Company has

concluded in good faith (after consultation with the Company’s outside legal and financial advisors and after complying with and giving effect to all proposed adjustments to this Agreement offered by Buyer pursuant to this Section 6.6(d)) (i)(x) in response to a bona fide written Competing Proposal that was unsolicited, that such proposal is a Superior Proposal, and (y) that the failure of the board of directors of the Company to change, qualify, withhold or withdraw the Company Recommendation would be inconsistent with the directors’ exercise of their fiduciary duties to the Company’s stockholders under applicable Law, or (ii) in the absence of a Competing Proposal, the failure of the board of directors of the Company to take such action would be inconsistent with the directors’ exercise of their fiduciary duties to the Company’s stockholders under applicable Law, the board of directors of the Company may, subject to complying with Section 8.2(a), (1) change, qualify, withhold or withdraw the Company Recommendation and/or (2) in the case of clause (i) of this sentence, terminate this Agreement to enter into a binding written agreement with respect to such Superior Proposal in accordance with Section 8.1(g); provided, that the Company shall not terminate this Agreement pursuant to the foregoing clause (2) and any purported termination pursuant to the foregoing clause (2) shall be void and of no force or effect unless, in advance of or concurrently with such termination, the Company (X) pays the Company Termination Fee, as required by Section 8.2, and (Y) simultaneously with such termination enters into an Acquisition Agreement with respect to a Competing Proposal and terminates this Agreement pursuant to Section 8.1(g); provided, further that prior to taking any of the actions described in clauses (i) and (ii) of this sentence, the Company shall have given Buyer at least three (3) business days’ written notice (it being understood and agreed that any material amendment to the amount or form of consideration of the Superior Proposal shall require a new notice and a new three (3) business day period) of the material terms of the Superior Proposal and the Company’s intention to accept such Superior Proposal, and the Company shall, during such three (3) business day period, negotiate in good faith with Buyer to make such adjustments to the Merger Consideration and other terms and conditions of this Agreement such that such Competing Proposal would no longer constitute a Superior Proposal. The board of directors of the Company shall promptly consider in good faith (in consultation with its outside legal counsel and financial advisors) any proposed alteration of the terms of this Agreement or the Merger proposed by Buyer in response to any Competing Proposal.

(e) In addition to the obligations of the Company set forth in Section 6.6(a), (b) and (c), the Company shall promptly (but in any event within 24 hours of receipt) notify Buyer of any (i) Competing Proposal, (ii) the material terms and conditions of any such Competing Proposal (including any material changes thereto), and (iii) the identity of the person making any such Competing Proposal. The Company shall promptly provide to Buyer any non-public information concerning the Company provided to any other person in connection with any Competing Proposal that was not previously provided to Buyer and any such non-public information shall be held by Buyer subject to the terms of the Confidentiality Agreement.

(f) Nothing contained in this Section 6.6 shall prohibit the Company or the board of directors of the Company from (i) disclosing to the Company’s stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or (ii) making any disclosure to its stockholders if the board of directors of the Company has reasonably determined in good faith, after consultation with outside legal counsel, that the failure to do so would be inconsistent with any applicable Law. The disclosures under this Section 6.6(f) shall

not be a basis, in themselves, for Buyer to terminate this Agreement pursuant to Section 8.1(f) so long as any such disclosure rejects any Competing Proposal and reaffirms the Company Recommendation.

(g) As used in this Agreement, “Competing Proposal” shall mean any proposal or offer from any third party (other than a proposal or offer by Buyer or any of its subsidiaries) relating to, or any inquiry that would reasonably be expected to lead to (i) a merger, consolidation, recapitalization, liquidation, dissolution, joint venture, binding share exchange, business combination or similar transaction involving the Company or any of its significant subsidiaries pursuant to which any person or the stockholders of any person would own twenty-five percent (25%) or more of any class of equity securities of the Company or any of its significant subsidiaries or of any resulting parent company of the Company; or (ii) any direct or indirect acquisition or purchase by any person, in one transaction or a series of transactions, that would constitute twenty-five percent (25%) or more of the revenues, net income or assets of the Company and its subsidiaries, taken as a whole (but exclusive of CPEX), or twenty-five percent (25%) or more of any class of equity securities of the Company or any of its significant subsidiaries.

(h) As used in this Agreement, “Superior Proposal” shall mean a Competing Proposal for or in respect of, or that if consummated would be reasonably likely to result in the ownership of, at least a majority of, the outstanding Company Common Stock (or of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or all or substantially all of the Company’s and its subsidiaries’, taken as a whole (but exclusive of CPEX), assets, made by any person on terms that the board of directors of the Company determines in good faith, after consultation with the Company’s financial and legal advisors, and considering such factors as the board of directors of the Company in good faith considers to be appropriate (including the conditionality and the timing, the likelihood of consummation of such proposal and the financing thereof), to be more favorable to the Company and its stockholders than the transactions contemplated by this Agreement and the Merger. Reference to “this Agreement” and “the Merger” in this Section 6.6(h) shall be deemed to include any proposed alteration of the terms of this Agreement or the Merger that is agreed to by Buyer after it receives written notice from the Company pursuant to Section 6.6(e) of the existence of, the identity of the person making and the material terms and conditions of, any Competing Proposal.

Section 6.7 Directors’ and Officers’ Indemnification and Insurance.

(a) Buyer and Acquisition Sub agree that all rights to exculpation and indemnification for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time (including any matters arising in connection with the transactions contemplated by this Agreement), now existing in favor of the current or former directors, officers or employees, as the case may be, of the Company or its subsidiaries (other than CPEX) as provided in their respective articles of association, certificates of incorporation or bylaws (or comparable organization documents) or agreements shall survive the Merger and shall continue in full force and effect. The Surviving Corporation shall (and Buyer shall cause the Surviving Corporation to) indemnify, defend and hold harmless, and advance expenses to Indemnitees with respect to all acts or omissions by them in their capacities as such at any time prior to the Effective Time, to the fullest extent required by: (i) the Company

Certificate or Company By-Laws and the organizational documents of the Company’s subsidiaries (other than CPEX), each as in effect on the date of this Agreement; and (ii) any indemnification agreements of the Company or its subsidiaries (other than CPEX) as in effect on the date of this Agreement, copies of which have been made available to Buyer. For the avoidance of doubt, nothing in this Section 6.7(a) shall affect the rights of any employee of CPEX existing pursuant to (i) the Company Certificate or Company By-Laws and the organizational documents of the Company’s subsidiaries (other than CPEX), each as in effect on the date of this Agreement; and (ii) any indemnification agreements of the Company or its subsidiaries (other than CPEX) as in effect on the date of this Agreement.

(b) Without limiting the provisions of Section 6.7(a), during the period beginning as of the Effective Time and ending on the sixth anniversary of the Effective Time, Buyer will: (i) indemnify and hold harmless each Indemnitee against and from any costs or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, to the extent such claim, action, suit, proceeding or investigation arises out of or pertains to: (A) any action or omission or alleged action or omission in such Indemnitee’s capacity as a director, officer or employee of the Company or any of its subsidiaries or affiliates; or (B) the Merger, the Merger Agreement and any transactions contemplated hereby; and (ii) pay in advance of the final disposition of any such claim, action, suit, proceeding or investigation the expenses (including attorneys’ fees) of any Indemnitee upon receipt of an undertaking by or on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified; provided, however, that the Surviving Corporation will not be liable for any settlement effected without the Surviving Corporation’s prior written consent (which shall not be unreasonably withheld, delayed or conditioned) and will not be obligated to pay the fees and expenses of more than one counsel for all Indemnitees in any jurisdiction with respect to any single such claim, action, suit, proceeding or investigation; provided that in the event any Indemnitee’s interests conflict with those of another Indemnitee with respect to any single such claim, action, suit, proceeding or investigation, the Surviving Corporation will be obligated to pay fees and expenses of one separate counsel for each such Indemnitee. Notwithstanding anything to the contrary contained in this Section 6.7(b) or elsewhere in this Agreement, the Surviving Corporation shall not (and Buyer shall cause the Surviving Corporation not to) settle or compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, action, suit, proceeding or investigation for which indemnification may be sought under this Section 6.7(b) unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnitees from all liability arising out of such claim, action, suit, proceeding or investigation.

(c) For six (6) years after the Effective Time, (i) Buyer shall maintain, or shall cause the Surviving Corporation to maintain, in effect the Company’s current directors’ and officers’ liability insurance, as disclosed or made available to Buyer prior to the date hereof (or such other insurance that is no less favorable to the Indemnitees than the Company’s current directors’ and officers’ liability insurance), in respect of acts or omissions occurring at or prior to the Effective Time, covering each Indemnitee currently covered by the Company’s directors’ and officers’ liability insurance policy, on terms with respect to such coverage and amounts no less favorable than those of such policy in effect on the date hereof; or (ii) Buyer or the Surviving

Corporation may substitute therefor a single premium tail policy with respect to such directors’ and officers’ liability insurance, as disclosed to Buyer prior to the date hereof, from an insurance carrier with the same or better AM Best rating as the Company’s current insurance carrier for such insurance policy, with a claims period of six (6) years from the Effective Time, and policy limits, terms and conditions (including deductibles and exclusions) at least as favorable to the directors and officers covered under such insurance policy as the limits, terms and conditions in the existing policies of the Company; provided, that in connection with this Section 6.7(c), neither the Surviving Corporation nor Buyer shall be obligated to pay annual premiums (in connection with any directors’ and officers’ liability insurance policy described in clause (c)(i) above) in excess of the annual premiums set forth in Section 6.7(c)(i) of the Company Disclosure Schedule, or pay a one-time premium (in connection with a single premium tail policy described in clause (c)(ii) above) in excess of the amount set forth in Section 6.7(c)(ii) of the Company Disclosure Schedule. It is understood and agreed that in the event such coverage cannot be obtained for such amount or less, then the Surviving Corporation shall obtain the maximum amount of coverage as may be obtained for such amount.

(d) Notwithstanding anything contained in Section 9.1 or Section 9.6 hereof to the contrary, this Section 6.7 shall survive the consummation of the Merger and shall be binding, jointly and severally, on all successors and assigns of Buyer, the Surviving Corporation and its subsidiaries, and shall be enforceable by the Indemnitees and their successors, heirs or representatives. In the event that the Surviving Corporation or any of its successors or assigns 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 transfers or conveys all or a majority of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation shall succeed to the obligations set forth in this Section 6.7.

Section 6.8 Notification of Certain Matters. The Company shall give prompt notice to Buyer, and Buyer shall give prompt notice to the Company, of (i) any notice or other communication received by such party from any Governmental Authority in connection with the this Agreement, the Merger or the transactions contemplated hereby, or from any person alleging that the consent of such person is or may be required in connection with the Merger or the transactions contemplated hereby, 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 Buyer and (ii) any inaccuracy of any representation or warranty made by such party that would reasonably be expected to cause the condition set forth in Section 7.2(a) or 7.3(a), respectively, not to be satisfied. The Company shall give prompt notice to Buyer of, and cooperate with Buyer in connection with, (i) any actions, suits, claims, investigations or proceedings commenced, pending, relating to, involving or, to the Company’s knowledge, threatened against or otherwise affecting the Company, any of its subsidiaries or their respective officers, directors or employees, which relate to this Agreement, the Merger or the transactions contemplated hereby and (ii) any stockholder litigation or claims against the Company, any of its subsidiaries or their respective officers, directors or employees relating to this Agreement, the Merger or the transactions contemplated hereby. No settlement in connection with any claim, suit, hearing, proceeding or litigation referred to in clause (i) or (ii) above shall be agreed to without Buyer’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 6.9 Public Announcements. Buyer and the Company shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or otherwise making any public statements with respect to the transactions contemplated by this Agreement, including the Merger, and shall not issue any such press release or make any such public statement without the prior consent of the other (which consent shall not be unreasonably withheld or delayed), except as may be required by Law or any stock exchange listing agreement to which Buyer or the Company is a party. Notwithstanding the foregoing, the Company shall be permitted to make such announcements and disclosures as it reasonably deems necessary or advisable to the extent such statements relate solely to the Spin-Off or the Drug Delivery Business. The parties agree that all formal Company employee communication programs or announcements with respect to the transactions contemplated by this Agreement, including the Merger, shall be in the forms mutually agreed to by the parties (such agreement not to be unreasonably withheld, delayed or conditioned). The parties agree that the initial press release to be issued with respect to the transactions contemplated by this Agreement shall be in the form heretofore agreed to by the parties.

Section 6.10 Employee Matters.

(a) As of the Effective Time, all rights and obligations arising from any employment contract or employment relationship existing in the Company or in any of its subsidiaries, shall be transferred to the Surviving Corporation.

(b) During the twelve (12) month period commencing on the Effective Time, Buyer shall provide or shall cause the Surviving Corporation to provide to (after giving effect to the Spin-Off) each current employee, officer, director or consultant of the Company and any of its subsidiaries at Closing (each, a “Company Employee” and collectively, the “Company Employees”) (i) compensation no less favorable than the compensation being provided to Company Employees immediately prior to the Effective Time (including equity-based compensation, as valued by Buyer in good faith), and (ii) benefits under employee benefit plans that are the same or substantially comparable in the aggregate to, in the sole discretion of Buyer, either (A) those currently provided by the Company and its Subsidiaries to such employees under the Company Benefit Plans as of the Closing Date (excluding equity-based plans) or (B) those provided by Buyer and its Subsidiaries to comparably situated employees from time to time during such twelve (12) month period.

(c) For purposes of eligibility, vesting, determination of the level of benefits and benefit accrual under the Employee Benefit Plans of Buyer, the Company, the Company’s subsidiaries and their respective affiliates providing benefits to any Company Employees after the Closing (the “New Plans”), and for purposes of accrual of vacation and other paid time off and severance benefits under New Plans, each Company Employee shall be credited with his or her years of service with the Company, the Company subsidiaries and their respective affiliates (and any additional service with any predecessor employer) before the Closing, to the same extent as such Company Employee was entitled, before the Closing, to credit for such service under any similar Company Benefit Plan. In addition, and without limiting the generality of the foregoing: (i) each Company Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan replaces coverage under a comparable Company Benefit Plan in which such Company Employee

participated immediately before the replacement; and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Company Employee, Buyer shall cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, and Buyer shall cause any eligible expenses incurred by such employee and his or her covered dependents under any Company Benefit Plan during the portion of the plan year of the New Plan ending on the date such employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan.

(d) Without limiting the generality of the foregoing, as of the Effective Time, Buyer shall cause the Surviving Corporation to honor in accordance with their terms all employment, change in control, severance and other compensation agreements and arrangements existing prior to the execution of this Agreement which are between the Company and any subsidiary and any Company Employee and set forth in Section 6.10(d) of the Company Disclosure Schedule (each, a “Company Executive Agreement”); subject, in each case, to any amendment or termination thereof that may be permitted by the terms of such agreements or arrangements; provided, that no such amendment or termination shall be effected by Buyer or the Surviving Corporation if it would adversely affect an employee’s (or former employee’s) rights resulting from the or relating to the Merger, this Agreement or the other transactions contemplated hereby. The Company and Buyer hereby agree that the occurrence of the Closing shall constitute a “Change in Control” for purposes of any Company Executive Agreement set forth in Section 6.10(d) of the Company Disclosure Schedule.

(e) Following the Effective Time, Buyer shall cause the Surviving Corporation and its subsidiaries to honor any Company collective bargaining agreements, and to preserve the status and functions of any union representative of the current Company Employees, or any current Company Employee serving as a liaison between the Company Employees and applicable unions, on the same terms and subject to the same conditions as existed prior to the Effective Time.

(f) If requested by Buyer at least five (5) business days prior to the Closing Date, the Company shall take (or cause to be taken) all actions reasonably necessary or appropriate to terminate, effective no later than the Effective Time, any Company Benefit Plan that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code (a “Company 401(k) Plan”). If the Company is required to terminate any Company 401(k) Plan, then the Company shall provide to Buyer prior to the Closing Date written evidence of the adoption by the Board of Directors of the Company of resolutions authorizing the termination of such Company 401(k) Plan (the form and substance of which resolutions shall be subject to the prior review and approval of Buyer, which approval shall not be unreasonably withheld or delayed).

(g) This Section 6.10 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 6.10, expressed or implied, is intended to confer upon any other person any rights or remedies of any nature whatsoever under

or by reason of this Section 6.10. Without limiting the foregoing, no provision of this Section 6.10 will create any third party beneficiary rights in any current or former employee, director or consultant of the Company or its subsidiaries in respect of continued employment (or resumed employment) or any other matter. Nothing in this Section 6.10 is intended to amend any Company Benefit Plan, or interfere with Buyer’s or the Surviving Corporation’s right from and after the Effective Time to amend or terminate any Company Benefit Plan or the employment or provision of services by any director, employee, independent contractor or consultant.

(h) For the avoidance of doubt, this Section 6.10 shall not apply to any current or former employees, officers, directors or consultants of CPEX.

(a) by mutual written consent of each of Buyer and the Company;

(b) by either Buyer or the Company, if (i) the Effective Time shall not have occurred on or before October 1, 2008 (the “Termination Date”) and (ii) the party seeking to

Section 9.5 Severability.
