(b) (i) Each share of Radius Series A-1 Stock issued and outstanding immediately prior to the Effective Time (other than shares cancelled and extinguished pursuant to this Section 2.2 and Dissenting Shares) shall automatically be converted into and exchangeable for a fraction of a fully paid and nonassessable share of MPMAC Series A-1 Stock equal to one multiplied by the Preferred Exchange Ratio;

(iii) Each share of Radius Series A-3 Stock issued and outstanding immediately prior to the Effective Time (other than shares cancelled and extinguished pursuant to this Section 2.2 and Dissenting Shares) shall automatically be converted into and exchangeable for a fraction of a fully paid and nonassessable share of MPMAC Series A-3 Stock equal to one multiplied by the Preferred Exchange Ratio;

(iv) Each share of Radius Series A-4 Stock issued and outstanding immediately prior to the Effective Time (other than shares cancelled and extinguished pursuant to this Section 2.2 and Dissenting Shares) shall automatically be converted into and

(c) All shares of Radius Common Stock and Radius Preferred Stock held at the Effective Time by Radius as treasury stock will be cancelled and extinguished and no payment will be made with respect to those shares;

(d) Each share of Radius Common Stock and Radius Preferred Stock issued and outstanding immediately prior to the Effective Time and owned by Merger Sub or MPMAC, if any, shall be cancelled and extinguished without any conversion thereof and no payment shall be made with respect thereto;

The Options shall be assumed in accordance with the terms and conditions of the Stock Option Plan, except that, from and after the Effective Time: (i) all actions to be taken under the Stock Option Plan or the Options by the Board of Directors of Radius or a committee thereof shall be taken by the Board of Directors of MPMAC or a committee thereof, (ii) each Option shall evidence the right to purchase a number of shares of MPMAC Common Stock (rounded to the nearest whole share) equal to the number of shares of Radius Common Stock into which such Option is exercisable immediately prior to the Effective Date multiplied by the Common Exchange Ratio, (iii) the new option price for each share of MPMAC Common Stock issuable upon exercise of an Option shall be determined by dividing the option exercise price immediately prior to the Effective Date by the Common Exchange Ratio (rounded to the nearest cent) and (iv) all references in the Options and the Stock Option Plan to Radius and Radius Common Stock shall be deemed to be references to MPMAC

and MPMAC Common Stock, respectively, after giving effect to the adjustments pursuant to clauses (ii) and (iii). Notwithstanding the provisions set forth in clause (iii) above, with respect to each Option intended to be an “incentive stock option” under Section 422 of the Code, if the new option price calculated pursuant to clause (iii) would cause any such Option not to satisfy the requirements of Section 424(a) of the Code and Treasury Regulation § 1.425-1(a)(1)(i), the new exercise price with respect to that Option will be increased to the minimum price that it could be and still satisfy the requirements of that regulation. MPMAC agrees to use its best efforts to take such other steps as are necessary to ensure that those Options which are deemed “incentive stock options” under Section 422 of the Code remain “incentive stock options;”

(g) MPMAC shall assume the rights and obligations under Radius’s outstanding warrants listed in Schedule 2.2(g) hereof (the “Warrants”), if any, to purchase shares of Radius Common Stock or Radius Preferred Stock. The Warrants shall be assumed in accordance with their terms and conditions. Each Warrant shall, from and after the Effective Time, evidence the right to purchase a number of shares of MPMAC Common Stock or MPMAC Preferred Stock (rounded to the nearest whole share) equal to the number of shares of Radius Common Stock or Radius Preferred Stock into which such Warrant is exercisable immediately prior to the Effective Date multiplied by the Common Exchange Ratio or Preferred Exchange Ratio, as applicable. The new exercise price of the Warrants shall be determined by dividing the exercise price of the Warrants immediately prior to the Effective Date by the Common Exchange Ratio or Preferred Exchange Ratio, as applicable. All references in the Warrants to Radius and Radius Common Stock or Radius Preferred Stock, as the case may be, shall be deemed to be references to MPMAC and MPMAC Common Stock or MPMAC Preferred Stock, as the case may be, respectively, after giving effect to the adjustments pursuant to this Section.

2.3 Rights of Holders of Certificates Evidencing Radius Capital Stock.

(a) On and after the Effective Date and until surrendered for exchange, each outstanding stock certificate that immediately prior to the Effective Date represented shares of Radius Common Stock (except Dissenting Shares and shares cancelled or extinguished pursuant to Section 2.2(d)) shall be deemed for all purposes, to evidence ownership of and to represent the number of whole shares of MPMAC Common Stock into which such shares of Radius Common Stock shall have been converted pursuant to Section 2.2(a) above. The record holder of each such outstanding certificate representing shares of Radius Common Stock, shall, after the Effective Date, be entitled to vote the shares of MPMAC Common Stock into which such shares of Radius Common Stock shall have been converted on any matters on which the holders of record of MPMAC Common Stock, as of any date subsequent to the Effective Date, shall be entitled to vote. In any matters relating to such certificates of Radius Common Stock, MPMAC may rely conclusively upon the record of stockholders maintained by Radius containing the names and addresses of the holders of record of Radius Common Stock on the Effective Date.

(b) On and after the Effective Date, each share of Radius Preferred Stock outstanding immediately prior to the Effective Time (except Dissenting Shares and shares cancelled or extinguished pursuant to Section 2.2(d)), each of which shall be uncertificated as of the Effective Date, as recorded on the books and records of Radius, shall be deemed for all

purposes, to evidence ownership of and to represent the number of whole shares of MPMAC Preferred Stock into which such shares of Radius Preferred Stock shall have been converted pursuant to Section 2.2(b) above. Shares of the MPMAC Preferred Stock shall have the terms, rights and preferences substantially set forth in the Certificate of Designation. The record holder of each such share of Radius Preferred Stock, shall, after the Effective Date, be entitled to vote the shares of MPMAC Preferred Stock into which such shares of Radius Preferred Stock shall have been converted on any matters on which the holders of record of MPMAC Preferred Stock, as of any date subsequent to the Effective Date, shall be entitled to vote. In any matters relating to the ownership of Radius Preferred Stock, MPMAC may rely conclusively upon the record of stockholders maintained by Radius containing the names and addresses of the holders of record of Radius Preferred Stock on the Effective Date.

2.4 Procedure for Exchange of Radius Capital Stock.

(a) After the Effective Time, holders of certificates theretofore evidencing outstanding shares of Radius Common Stock (except Dissenting Shares and shares cancelled or extinguished pursuant to Section 2.2(d)), upon surrender of such certificates together with the delivery of a letter of transmittal in the form of Exhibit C hereto (the “Letter of Transmittal”) duly completed and validly executed in accordance with the instructions thereto to the Secretary of MPMAC, shall be entitled to receive certificates representing the number of shares of MPMAC Common Stock into which shares of Radius Common Stock theretofore represented by the certificates so surrendered are exchangeable as provided in Section 2.2(a) hereof. MPMAC shall not be obligated to deliver any such shares of MPMAC Common Stock to which any former holder of shares of Radius Common Stock is entitled until such holder surrenders the certificate or certificates representing such shares. Upon surrender, each certificate evidencing Radius Common Stock shall be cancelled. No certificates or scrip representing fractional shares of MPMAC Common Stock or MPMAC Preferred Stock shall be issued in the Merger, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of the Surviving Corporation. Upon surrender of Radius Common Stock or Radius Preferred Stock, as the case may be, each holder of a fractional MPMAC Common Stock or MPMAC Preferred Stock interest that would have been issued in the Merger but for the foregoing sentence shall be paid by MPMAC an amount in cash equal to the product obtained by multiplying (i) such fractional share interest to which such holder (after taking into account all fractional share MPMAC Common Stock or MPMAC Preferred Stock interests, as applicable, then held by such holder) would otherwise be entitled, by (ii) $8.142. If there is a transfer of Radius Common Stock ownership which is not registered in the transfer records of Radius, a certificate representing the proper number of shares of MPMAC Common Stock may be issued to a person other than the person in whose name the certificate so surrendered is registered if: (x) upon presentation to the Secretary of MPMAC, such certificate shall be properly endorsed or otherwise be in proper form for transfer, (y) the person requesting such payment shall pay any transfer or other Taxes required by reason of the issuance of shares of MPMAC Common Stock to a person other than the registered holder of such certificate or establish to the reasonable satisfaction of MPMAC that such Tax has been paid or is not applicable, and (z) the issuance of such MPMAC Common Stock shall not, in the sole discretion of MPMAC, violate the requirements of the Regulation D “safe harbor” of the Securities Act with respect to the private placement of MPMAC Common Stock that will result from the Merger.

(b) For each outstanding share of Radius Preferred Stock recorded on the books and records of Radius immediately prior to Effective Time (except Dissenting Shares and shares cancelled or extinguished pursuant to Section 2.2(d)), MPMAC shall record in its books and records, immediately after the Effective Time (or as soon thereafter as reasonably practicable), in the respective name of such holder as set forth in the Radius books and records, the number of shares of MPMAC Preferred Stock into which the shares of Radius Preferred Stock are exchangeable as provided in Section 2.2(b) hereof. Upon surrender of a Letter of Transmittal duly completed and validly executed in accordance with the instructions thereto to the Secretary of MPMAC, holders of Radius Preferred Stock shall be entitled to receive certificates representing the number of shares of MPMAC Preferred Stock into which shares of Radius Preferred Stock are exchangeable as provided in Section 2.2(b) hereof. If there is a transfer of Radius Preferred Stock ownership which is not registered in the transfer records of Radius, the proper number of shares of MPMAC Preferred Stock subject to such transfer may be recorded in the name of a person other than the person in whose name the shares so surrendered are registered if: (x) upon presentation to the Secretary of MPMAC, the transfer of such shares shall be properly endorsed or otherwise be in proper form for transfer, (y) the person requesting such payment shall pay any transfer or other Taxes required by reason of the issuance of shares of MPMAC Preferred Stock to a person other than the registered holder of such shares or establish to the reasonable satisfaction of MPMAC that such Tax has been paid or is not applicable, and (z) the issuance of such MPMAC Preferred Stock shall not, in the sole discretion of MPMAC, violate the requirements of the Regulation D “safe harbor” of the Securities Act with respect to the private placement of MPMAC Preferred Stock that will result from the Merger.

(c) All shares of MPMAC Common Stock and MPMAC Preferred Stock issued upon the surrender for exchange of Radius Common Stock and Radius Preferred Stock, respectively, in accordance with the above terms and conditions shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such shares of Radius Common Stock and Radius Preferred Stock, respectively.

(d) Any shares of MPMAC Common Stock or MPMAC Preferred Stock issued in the Merger will not be transferable except (1) pursuant to an effective registration statement under the Securities Act or (2) upon receipt by MPMAC of a written opinion of counsel for the holder reasonably satisfactory to MPMAC to the effect that the proposed transfer is exempt from the registration requirements of the Securities Act and relevant state securities laws. Restrictive legends shall be placed on all certificates representing shares of MPMAC Common Stock and MPMAC Preferred Stock, as applicable, issued in the Merger, substantially as follows:

“NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE MADE EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND REGULATIONS IN EFFECT THEREUNDER AND ALL APPLICABLE STATE SECURITIES OR

“BLUE SKY” LAWS (SUCH FEDERAL AND STATE LAWS, THE “SECURITIES LAWS”) OR (B) IF THE CORPORATION HAS BEEN FURNISHED WITH AN OPINION OF COUNSEL FOR THE HOLDER, WHICH OPINION AND COUNSEL SHALL BE REASONABLY SATISFACTORY TO THE CORPORATION, TO THE EFFECT THAT SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION IS EXEMPT FROM THE PROVISIONS OF THE SECURITIES LAWS.

(e) In the event any certificate for Radius Common Stock or any certificate or similar instrument evidencing Radius Preferred Stock, Options, Warrants or Convertible Securities shall have been lost, stolen or destroyed, MPMAC shall issue and pay in exchange for such lost, stolen or destroyed certificate, promptly following its receipt of an affidavit of that fact by the holder thereof, such shares of the MPMAC Common Stock or MPMAC Preferred Stock, as applicable, as may be required pursuant to this Agreement; provided, however, that MPMAC, in its discretion and as a condition precedent to the issuance and payment thereof, may require the owner of such lost, stolen or destroyed certificate to deliver a bond in such sum as it may direct as indemnity against any claim that may be made against MPMAC or any other party with respect to the certificate alleged to have been lost, stolen or destroyed.

2.5 Dissenting Shares. Shares of capital stock of Radius held by stockholders of Radius who have properly exercised and preserved appraisal rights with respect to those shares in accordance with Section 262 of the DGCL (“Dissenting Shares”) shall not be converted into or represent a right to receive shares of MPMAC Common Stock or MPMAC Preferred Stock, as applicable, pursuant to Section 2.2 above, but the holders thereof shall be entitled only to such rights as are granted by Section 262 of the DGCL. Each holder of Dissenting Shares who becomes entitled to payment for such shares pursuant to Section 262 of the DGCL shall receive payment therefor from the Surviving Company in accordance with such laws; provided, however, that if any such holder of Dissenting Shares shall have effectively withdrawn such holder’s demand for appraisal of such shares or lost such holder’s right to appraisal and payment of such shares under Section 262 of the DGCL, such holder or holders (as the case may be) shall forfeit the right to appraisal of such shares and each such share shall thereupon be deemed to have been cancelled, extinguished and exchanged, as of the Effective Time, into and represent the right to receive from MPMAC shares of MPMAC Common Stock or MPMAC Preferred Stock, as applicable, as provided in Section 2.2 above. Any payments in respect of Dissenting Shares will be deemed made by the Surviving Company.

All of the persons serving as directors of MPMAC immediately prior to the Closing and will not continue in such capacity after the Closing shall resign immediately following the election of the new directors, all subject to compliance with Rule 14f-1 promulgated under the Exchange Act. Subject to applicable law, MPMAC shall take all action reasonably requested by Radius, but consistent with the Certificate of Incorporation and Bylaws of MPMAC, that is reasonably necessary to effect any such election or appointment of the designees of Radius to MPMAC’s Board of Directors, including promptly hereafter mailing to MPMAC’s stockholders an information statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. Radius shall supply MPMAC all information with respect to it and its nominees, officers, directors and Affiliates required by such Section 14(f) and Rule 14f-1.

The copies of the Certificate of Incorporation and Bylaws of MPMAC and Merger Sub that have been made available to Radius on or prior to the date of this Agreement are correct and complete copies of such documents as in effect as of the date hereof, and shall be in effect on the Effective Date. MPMAC and Merger Sub are, and on the Effective Date each will be, licensed or qualified to do business in every jurisdiction which the nature of their respective businesses or their respective ownership of properties require each to be licensed or qualified, except where the failure to be so licensed or qualified would not have a Material Adverse Effect on MPMAC or Merger Sub, respectively.

4.2 Authority Relative to this Agreement; Non-Contravention. Each of MPMAC and Merger Sub has the requisite corporate power and authority to enter into this Agreement, and to carry out its obligations hereunder. The execution and delivery of this Agreement by MPMAC and Merger Sub, and the consummation by MPMAC and Merger Sub of the transactions contemplated hereby have been duly authorized by the Boards of Directors of MPMAC and Merger Sub. Subject only to the adoption of this Agreement by MPMAC as the sole stockholder of Merger Sub, with respect to which MPMAC will take appropriate action promptly following the date hereof, no further corporate proceedings on the part of MPMAC or Merger Sub are necessary to authorize the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby or will otherwise be sought by MPMAC. This Agreement has been duly executed and delivered by MPMAC and Merger Sub and, assuming it is a valid and binding obligation of Radius, constitutes a valid and binding obligation of MPMAC and Merger Sub enforceable in accordance with its terms except as enforcement may be limited by

general principles of equity whether applied in a court of law or a court of equity and by bankruptcy, insolvency and similar laws affecting creditors’ rights and remedies generally. Except for (x) approvals under applicable Blue Sky laws and the filing of Form D with the Securities and Exchange Commission and (y) the filing of the Certificate of Merger with the Delaware Secretary of State, no authorization, consent or approval of, or filing with, any public body, court or authority is necessary on the part of MPMAC or Merger Sub for the consummation by MPMAC or Merger Sub of the transactions contemplated by this Agreement, except for such authorizations, consents, approvals and filings as to which the failure to obtain or make the same would not, in the aggregate, reasonably be expected to have a Material Adverse Effect on MPMAC or Merger Sub, or adversely affect the consummation of the transactions contemplated hereby.

4.3 No Conflicts. Neither MPMAC nor Merger Sub is subject to, or obligated under, any provision of (a) their respective Certificates of Incorporation or Bylaws, (b) any agreement, arrangement or understanding, (c) any license, franchise or permit, nor (d) subject to obtaining the approvals referred to in the next sentence, any law, regulation, order, judgment or decree, which would conflict with, be breached or violated, or in respect of which a right of termination or acceleration or any security interest, charge or encumbrance on any of their respective assets would be created, by the execution, delivery or performance of this Agreement or the consummation of the transactions contemplated hereby, other than any such conflicts, breaches, violations, rights of termination or acceleration or security interests, charges or encumbrances which, in the aggregate, could not reasonably be expected to have a Material Adverse Effect on MPMAC or Merger Sub.

The issued and outstanding shares of capital stock of MPMAC are, and on the Effective Date will be, duly authorized, validly issued, fully paid and nonassessable and not issued in violation of any preemptive rights and, to MPMAC’s Knowledge, free from any restrictions on transfer (other than restrictions under the Securities Act or state securities laws) or any option, lien, pledge, security interest, encumbrance or charge of any kind.

The

redemption of such shares shall become effective concurrently with the Effective Time. Other than the shares of MPMAC Common Stock and MPMAC Preferred Stock comprising the Merger Consideration, upon the consummation of such redemption, there will be no other shares of MPMAC Common Stock or MPMAC Preferred Stock outstanding. There are, and on the Effective Date there will be, no agreements or other obligations (contingent or otherwise) which may require MPMAC to repurchase or otherwise acquire any shares of its capital stock other than the Redemption Agreement.

4.5 Exchange Act Reports; Financial Statements.

(a) Since the filing of MPMAC’s Registration Statement on Form 10 on April 16, 2008 (the “MPMAC Form 10”), MPMAC has timely filed all reports, forms and documents that it was required to file with the SEC pursuant to Section 13(a), 14(a), 14(c) and 15(d) of the Exchange Act (together with the MPMAC Form 10, the “MPMAC Previous Filings”). MPMAC shall notify Radius promptly of the filing of any additional forms, reports or documents with the SEC by MPMAC after the date hereof and prior to the Effective Time (together with the MPMAC Previous Filings, the “MPMAC SEC Filings”). As of their respective filing dates, each of the MPMAC SEC Filings (i) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading and (ii) complied as to form in all material respects with the Exchange Act and the applicable rules and regulations of the SEC promulgated thereunder.

(b) The financial statements (including footnotes thereto) included in or incorporated by reference into the MPMAC SEC Filings (the “MPMAC Financial Statements”) were complete and correct in all material respects as of their respective filing dates, complied as to form in all material respects with the Exchange Act and the applicable accounting requirements, rules and regulations of the SEC promulgated thereunder as of their respective

dates and have been prepared in accordance with GAAP applied on a consistent basis during the periods involved (except as otherwise noted therein). The MPMAC Financial Statements fairly present the financial condition of MPMAC as of the dates thereof and results of operations for the periods referred to therein (subject, in the case of unaudited MPMAC Financial Statements, to normal recurring year-end adjustments). There has been no change in MPMAC accounting policies except as described in the notes to the MPMAC Financial Statements.

4.6 Litigation. There are no actions, suits, proceedings, orders or investigations pending or, to the Knowledge of MPMAC, threatened against MPMAC, Merger Sub, or MPMAC’s officers, directors or employees, individually or in the aggregate, at law or in equity, or before or by any federal, state or other governmental department, court, commission, board, bureau, agency or instrumentality, domestic or foreign, and to the Knowledge of MPMAC, there is no reasonable basis for any proceeding, claim, action or governmental investigation directly or indirectly involving MPMAC, Merger Sub, or MPMAC’s officers, directors, or employees, individually or in the aggregate. Neither MPMAC nor Merger Sub are a party to any order, judgment or decree issued by any federal, state or other governmental department, court, commission, board, bureau, agency or instrumentality, domestic or foreign.

4.7 Subsidiaries. Merger Sub is MPMAC’s only subsidiary, direct or indirect. MPMAC owns all of the outstanding shares of capital stock of Merger Sub and all such shares are duly authorized, validly issued, fully paid and nonassessable and not subject to preemptive rights or encumbrances.

4.8 No Brokers or Finders. None of MPMAC or any of its officers, directors, employees or Affiliates has employed any broker, finder, investment banker or investment advisor or Person performing a similar function, or incurred any liability for brokerage commissions, finders’ fees, investment advisory fees or similar compensation in connection with the transactions contemplated by this Agreement.

There has been no Tax audit or other administrative proceeding or court proceeding with regard to any Taxes or MPMAC Returns, nor is any such Tax audit or other proceeding pending, nor has there been any notice to MPMAC by any Taxing authority regarding any such Tax audit or other proceeding, or, to the Knowledge of MPMAC, is any such Tax audit or other proceeding threatened with regard to any Taxes or MPMAC Returns. MPMAC does not expect the assessment of any additional Taxes of MPMAC for any period prior to the date hereof and has no Knowledge of any unresolved questions, claims or disputes concerning the liability for Taxes of MPMAC which would exceed the estimated reserves established on its books and records.

(d) MPMAC is not a party to any agreement, contract or arrangement that would result, separately or in the aggregate, in the payment of any “excess parachute payments” within the meaning of Section 280G of the Code and the consummation of the transactions contemplated by this Agreement will not be a factor causing payments to be made by MPMAC not to be deductible (in whole or in part) under Section 280G of the Code. MPMAC is not liable for Taxes of any other Person, and is not currently under any contractual obligation to indemnify any Person with respect to Taxes, or a party to any Tax sharing agreement or any other agreement providing for payments by MPMAC with respect to Taxes. MPMAC is not a party to any joint venture, partnership or other arrangement or contract which could be treated as a partnership for federal income Tax purposes.

MPMAC has no property, sales or payroll in any state creating a Tax nexus. No claim has ever been made by a Taxing authority in a jurisdiction where MPMAC does not currently file MPMAC Returns that MPMAC is or may be subject to Tax imposed by that jurisdiction. There are no advance rulings in respect of any Tax pending or issued by any Taxing authority with respect to any Taxes of MPMAC. MPMAC has not entered into any gain recognition agreements under Section 367 of the Code and the regulations promulgated thereunder. MPMAC is not liable with respect to any indebtedness the interest of which is not deductible for applicable federal, foreign, state or local income Tax purposes.

In light of the foregoing, each party shall permit the other party full access on reasonable notice and at reasonable hours to its properties and shall disclose and make available (together with the right to copy) to the other party and its officers, employees, attorneys, accountants and other representatives (hereinafter collectively referred to as “Representatives”), all books, papers, and records relating to the assets, stock, properties, operations, obligations and liabilities of such party and its subsidiaries, including, without limitation, all books of account (including, without limitation, the general ledger), Tax records, minute books of directors’ and stockholders’ meetings, organizational documents, bylaws, contracts and agreements, filings with any regulatory authority, accountants’ work papers, litigation files (including, without limitation, legal research memoranda), attorney’s audit response letters, documents relating to assets and title thereto (including, without limitation, abstracts, title insurance policies, surveys, environmental reports, opinions of title and other information relating to the real and personal property), plans affecting employees, securities transfer records and stockholder lists, and any books, papers and records (collectively referred to herein as “Evaluation Material”) relating to other assets or business activities in which such party may have a reasonable interest, and otherwise provide such assistance as is reasonably requested in order that each party may have a full opportunity to make such investigation and evaluation as it shall reasonably desire to make of the business and affairs of the other party; provided, however, that the foregoing rights granted to each party shall, whether or not and regardless of the extent to which the same are exercised, in no way affect the nature or scope of the representations, warranties and covenants of the respective party set forth herein. In addition, each party and its Representatives shall cooperate fully (including providing introductions, where necessary) with such other party to enable the party to contact third parties, including customers, prospective customers, specified agencies or others as the party deems reasonably necessary to complete its due diligence; provided that such party agrees not to initiate such contacts without the prior approval of the other party, which approval will not be unreasonably withheld.

(b) Radius and MPMAC agree that each such party will not use the Evaluation Material for any purpose other than in connection with the Merger and the transactions contemplated hereunder. Each agrees not to disclose or allow disclosure to others of any Evaluation Material, except to such party’s Affiliates or Representatives, in each case, to the extent necessary to permit such Affiliate or Representative to assist such party in connection with the Merger and the transactions contemplated hereunder. Each agrees that it will, within ten (10) days of the other party’s request, re-deliver to such party all copies of that party’s Evaluation Material in its possession or that of its Affiliates or Representatives if the Merger does not close as contemplated herein.

(c) In the event any party or anyone to whom Evaluation Material has been transmitted in accordance with the terms herein is requested in connection with any proceeding to disclose any Evaluation Material, or a party has determined that it is required under applicable law or regulation to disclose Evaluation Material, such party will give the other party prompt notice of such request or determination so that the other party may seek an appropriate protective

order or other remedy or waive compliance with this Agreement, and such party will cooperate with the other party to obtain such protective order. In the event such protective order is not obtained, the other party waives compliance with the relevant provisions of this Section, such party (or such person to whom such request is directed) will furnish only that portion of the Evaluation Material which is required to be disclosed. The parties acknowledge that, upon execution and delivery, this Agreement (but not the exhibits and schedules thereto) will be filed by MPMAC with the SEC under cover of Form 8-K.

(d) Notwithstanding any of the foregoing, if prior to Closing, for any reason, the transactions contemplated by this Agreement are not consummated, neither MPMAC nor Radius nor any of their Representatives shall disclose to third parties or otherwise use any Evaluation Material or other confidential information received from the other party in the course of investigating, negotiating, and performing the transactions contemplated by this Agreement; provided, however, that nothing shall be deemed to be confidential information which:

(i) is or becomes generally available to the public other than as a result of a disclosure by such party, its affiliates or Representatives;

(ii) was available to such party on a non-confidential basis prior to its disclosure;

(iii) becomes available to such party on a non-confidential basis from a source other than the other party or its agents, advisors or Representatives;

(iv) developed by such party independently of any disclosure by the other party; or

(v) is disclosed in compliance with Section 6.3(c).

Nothing in this Section 6.3 shall prohibit the disclosure of information required to be made under federal or state securities laws. If any disclosure is so required, the party making such disclosure shall consult with the other party prior to making such disclosure, and the parties shall use all reasonable efforts, acting in good faith, to agree upon a text for such disclosure which is satisfactory to both parties.

(e) MPMAC and Radius each agree that money damages would not be sufficient to remedy any breach by the other party of this Section, and that, in addition to all other remedies, each party against which a breach of this Section has been committed shall be entitled to specific performance and injunctive or other equitable relief as a remedy of such breach.

6.4 Tax Treatment. It is intended by the parties hereto that the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Code. Each of the parties hereto adopts this Agreement as a “plan of reorganization” within the meaning of Treasury Regulation § 1.368-2(g) and 1.368-3(a). Both prior to and after the Closing, each party’s books and records shall be maintained, and all federal, state and local income Tax returns and schedules

thereto shall be filed in a manner consistent with the Merger being qualified as a reorganization under Section 368(a) of the Code (and comparable provisions of any applicable state or local laws); except to the extent the Merger is determined in a final administrative or judicial decision not to qualify as such a reorganization within the meaning of Code Section 368(a). Each of Radius and MPMAC and their respective Affiliates agree to provide the customary representations, assumptions and qualifications regarding the treatment of the Merger and this Agreement as a reorganization within the meaning of Section 368(a) of the Code.

6.5 Press Releases. Radius and MPMAC shall agree with each other as to the form and substance of any press release or public announcement related to this Agreement or the transactions contemplated hereby; provided, however, that nothing contained herein shall prohibit either party, following notification to the other party, from making any disclosure which is required by law or regulation. If any such press release or public announcement is so required, the party making such disclosure shall consult with the other party prior to making such disclosure, and the parties shall use all reasonable efforts, acting in good faith, to agree upon a text for such disclosure which is satisfactory to both parties.

6.6 Securities Reports. MPMAC shall timely file with the SEC all reports and other documents required to be filed under the Securities Act or Exchange Act. All such reports and documents (i) shall not, as of the date of such filing, contain any untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (ii) shall comply as to form, in all material respects, with the applicable rules and regulations of the SEC. MPMAC agrees to provide to Radius copies of all reports and other documents filed under the Securities Act or Exchange Act with the SEC by it between the date hereof and the Effective Date within two (2) days after the date such reports or other documents are filed with the SEC.

6.7 Private Placement. Each of Radius and MPMAC shall take all necessary action on its part such that the issuance of the Merger Consideration to Radius stockholders constitutes a valid “private placement” under the Securities Act. Without limiting the generality of the foregoing, Radius shall (1) provide each Radius stockholder with a stockholder qualification questionnaire in the form reasonably acceptable to both MPMAC and Radius (a “Stockholder Questionnaire”) and (2) use its commercially reasonably best efforts to cause each Radius stockholder to truthfully attest that (i) such stockholder is acquiring the Merger Consideration for his, her or its sole account, for investment and not with a view to the resale or distribution thereof and (ii) that stockholder either (A) is an “accredited investor” as defined in Regulation D of the Securities Act, (B) has such knowledge and experience in financial and business matters that the stockholder is capable of evaluating the merits and risks of receiving the Merger Consideration, or (C) has appointed an appropriate person reasonably acceptable to both MPMAC and Radius to act as the stockholder’s purchaser representative in connection with evaluating the merits and risks of receiving the Merger Consideration.

6.8 Radius Stockholders’ Meeting; Materials to Stockholders.

(a) Radius shall, in accordance with Section 251 of the DGCL and its certificate of incorporation and by-laws, duly call, give notice of, convene and hold a special

meeting of Radius Stockholders (the “Radius Stockholder Meeting”) as promptly as practicable after the date hereof for the purpose of considering and taking action upon this Agreement and the Merger. Alternatively, Radius shall use its best efforts to obtain, in lieu of holding the Radius Stockholder Meeting, the written consent of the number of Radius stockholders necessary under its Certificate of Incorporation, Bylaws and the DGCL to approve this Agreement and the Merger.

(b) Radius shall as promptly as practicable following the date of this Agreement prepare and mail to Radius stockholders all information as may required to comply with the DGCL, the Securities Act and the Exchange Act.

6.9 No Solicitation.

(a) Unless and until this Agreement shall have been terminated pursuant to Section 8.1, neither MPMAC nor its officers, directors or agents shall, directly or indirectly, encourage, solicit or initiate discussions or negotiations with, or engage in negotiations or discussions with, or provide non-public information to, any Person or group of Persons concerning any merger, sale of capital stock, sale of substantial assets or other business combination; provided, however, that MPMAC may engage in such discussion and provide such non-public information (subject to obtaining confidentiality agreements) in response to an unsolicited proposal from an unrelated party if the Board of Directors of MPMAC determines, in good faith, after consultation with counsel, that the failure to engage in such discussions and provide such non-public information (subject to obtaining confidentiality agreements) may constitute a breach of the fiduciary or legal obligations of the Board of Directors of MPMAC. MPMAC will promptly advise Radius if it receives a proposal or inquiry with respect to the matters described above.

(b) Unless and until this Agreement shall have been terminated pursuant to Section 8.1, neither Radius nor its officers, directors or agents shall, directly or indirectly, encourage, solicit or initiate discussions or negotiations with, or engage in negotiations or discussions with, or provide non-public information to, any Person or group of Persons concerning any merger, sale of capital stock, sale of substantial assets or other business combination; provided, however, that Radius may engage in such discussion in response to any unsolicited proposal from an unrelated party if the Board of Directors of Radius determines, in good faith, after consultation with counsel, that the failure to engage in such discussions and provide such non-public information (subject to obtaining confidentiality agreements) may constitute a breach of the fiduciary or legal obligations of the Board of Directors of Radius. Radius will promptly advise MPMAC if it receives a proposal or inquiry with respect to the matters described above.

In the event that either of the parties hereto determines that a condition to its respective obligations to consummate the transactions contemplated hereby cannot be fulfilled on or prior to the termination of this Agreement, it will promptly notify the other party.

6.11 Notification of Certain Matters. On or prior to the Effective Date, each party shall give prompt notice to the other party of (i) the occurrence or failure to occur of any event or the discovery of any information, which occurrence, failure or discovery would be likely to cause any representation or warranty on its part contained in this Agreement to be untrue, inaccurate or incomplete after the date hereof in any material respect or, in the case of any representation or warranty given as of a specific date, would be likely to cause any such representation or warranty on its part contained in this Agreement to be untrue, inaccurate or incomplete in any material respect as of such specific date, and (ii) any material failure of such party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereunder.

6.12 Customary Representations, Assumptions and Qualifications.

(d) If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series A-2 Stockholders the full amount to which each of them shall be entitled pursuant to Section 4(b) above and to pay to the holders of any other class or series of capital stock that is on a parity with the Series A-2 Stock upon Liquidation the full amount to which each of such holders shall be entitled pursuant to Section 4(b) or any other section of this Certificate as in effect from time to time, then the Series A-2 Stockholders and such holders shall share ratably in any distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series A-2 Stock and the shares of such other class or series of capital stock held upon such distribution if all amounts payable on or with respect to< all of> such shares were paid in full.

(e) If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series A-3 Stockholders, the Series A-5 Stockholders and the Series A-6 Stockholders the full amount to which each of them shall be entitled pursuant to Section 4(b) above and to pay to the holders of any other class or series of capital stock that is on a parity with the Series A-3, Series A-5 Stock and the Series A-6 Stock upon Liquidation the full amount to which each of such holders shall be entitled pursuant to Section 4(b) or any other section of this Certificate as in effect from time to time, then the Series A-3 Stockholders, the Series A-5 Stockholders, the Series A-6 Stockholders and such holders shall share ratably in any distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series A-3 Stock, Series A-5 Stock and Series A-6 Stock and the shares of such other class or series of capital stock, as the case may be, held upon such distribution if all amounts payable on or with respect to all of such shares were paid in full.

(f) If, upon any Liquidation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series A-4 Stockholders the full amount to which each of them shall be entitled pursuant to Section 4(b) above and to pay to the holders of any other class or series of capital stock that is on a parity with the Series A-4 Stock

upon Liquidation the full amount to which each of such holders shall be entitled pursuant to Section B.4(b) or any other section of this Certificate as in effect from time to time, then the Series A-4 Stockholders and such holders shall share ratably in any distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series A-4 Stock and the shares of such other class or series of capital stock held upon such distribution if all amounts payable on or with respect to all of such shares were paid in full.

(g) In the event of any Liquidation, after payment shall have been made to the Preferred Stockholders of the full amount to which they shall be entitled pursuant to Section 4(b) and to the holders of any class or series of capital stock that is senior to or on parity with the Preferred Stock, or any series, thereof, as in effect from time to time, the holders of each other class or series of capital stock (other than Common Stock) ranking on Liquidation junior to the Preferred Stock, but senior to the Common Stock, as a class, shall be entitled to receive an amount equal (and in like kind) to the aggregate preferential amount fixed for each such junior class or series of capital stock. If, upon any Liquidation, after payment shall have been made to the Preferred Stockholders of the full amount to which they shall be entitled pursuant to Section 4(b), the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay a class or series of capital stock (other than the Common Stock) junior to the Preferred Stock the full amount to which they shall be entitled pursuant to the preceding sentence, the holders of such other class or series of capital stock shall share ratably, based upon the number of then outstanding shares of such other class or series of capital stock, in any remaining distribution of assets according to the respective preferential amounts fixed for such junior class or series of capital stock or which would be payable to them in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(h) In the event of any Liquidation, after payments shall have been made first to the Preferred Stockholders and to the holders of any class or series of capital stock that is senior to or on parity with the Preferred Stock, or any series thereof, as in effect from time to time, and to the holders of class or series of capital stock that is junior to or on parity with the Preferred Stock but senior to the Common Stock, of the full amount to which they each shall be entitled as aforesaid, the holders of Common Stock, as a class, shall be entitled to share ratably with the holders of Participating Preferred Stock as provided in the last sentence in this Section 4(h)) in all remaining assets of the Corporation legally available for distribution to its stockholders. For purposes of calculating the amount of any payment to be paid upon any such Liquidation pursuant to the participation feature described in this Section 4(h), each share of such Participating Preferred Stock shall be deemed to be that number of shares (including fractional shares and any shares attributable to the payment of accrued and unpaid dividends upon conversion of such Participating Preferred Stock pursuant to Section 7(b)) of Common Stock into which it is then convertible, rounded to the nearest one-tenth of a share.

(i) (i) In the event of and simultaneously with the closing of an Event of Sale, the Corporation shall, unless waived by the Senior Majority or otherwise prevented by law, redeem all of the shares of Preferred Stock then outstanding for a cash amount per share determined as set forth in Sections Section 4(a) through (h) hereof (the “Special Liquidation Price,” said redemption being referred to herein as a “Special Liquidation”). In the event the Event of Sale involves consideration that does not consist of cash, then the Special Liquidation Price may be paid with such consideration having a value equal to the Special Liquidation Price. To the extent there is

any cash consideration in connection with an Event of Sale, at the option of the Senior Majority, the cash consideration will first (i) be applied to satisfy the Special Liquidation Price payable to the Series A-1 Stockholders and to the holders of any other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation; and then (ii) be applied to satisfy the Special Liquidation Price payable to the holders of Series A-2 Stock and to the holders of any other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the Series A-2 Stock as to Liquidation; and then (iii) be applied to satisfy the Special Liquidation Price payable to holders of Series A-3 Stock, Series A-5 Stock, Series A-6 Stock and any other class or series of capital stock that is junior to the Series A-2 Stock but senior to or on parity with the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock as to Liquidation (in relative proportion to the full liquidation preference the Series A-3 Stockholders, Series A-5 Stockholders, Series A-6 Stockholders and the holders of such other class or series of capital stock would have received had there been sufficient cash consideration to have paid their liquidation preference in full) and then (iv) be applied to satisfy the Special Liquidation Price payable to the holders of Series A-4 Stock and to the holders of any other class or series of capital stock that is junior to the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock but senior to or on parity with the Series A-4 Stock, in all cases, prior to the payment thereof to any other stockholders of the Corporation. For all purposes of this Section 4(i), the Special Liquidation Price shall be equal to that amount per share which would be received by each Preferred Stockholder if, in connection with an Event of Sale, all the consideration paid in exchange for the assets or the shares of capital stock (as the case may be) of the Corporation were actually paid to and received by the Corporation and the Corporation were immediately thereafter liquidated and its assets distributed pursuant to Sections 4(a) through (h) hereof. To the extent that one or more redemptions (as described in Section 5 hereof) and/or Special Liquidations are occurring concurrently, the Special Liquidation under this Section 4(i) shall be deemed to occur first. The date upon which the Special Liquidation shall occur is sometimes referred to herein as the “Special Liquidation Date”.

(ii) In the absence of an applicable waiver pursuant to Section 4(i) above, at any time on or after the Special Liquidation Date, a Preferred Stockholder shall be entitled to receive the Special Liquidation Price for each such share of Preferred Stock owned by such holder. Subject to the provisions of Section 4(i)(iii) hereof, payment of the Special Liquidation Price will be made to each such holder upon actual delivery to the Corporation or its transfer agent of the certificate of such holder representing such shares of Preferred Stock, as the case may be, or an affidavit of loss as to the same.

(iii) If on the Special Liquidation Date less than all the shares of Preferred Stock then outstanding may be legally redeemed by the Corporation, the Special Liquidation shall be made first as to the Series A-1 Stock (and any other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation), pro rata with respect to such Series A-1 Stock (or such other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation) based upon the number of outstanding shares of Series A-1 Stock (or such other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation) then owned by each such holder thereof until such holders are satisfied in full, and then to the Series A-2 Stock (and any other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the Series A-2 Stock as to Liquidation), pro rata with respect to such Series A-2 Stock (or such other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the

Series A-2 Stock as to Liquidation) based upon the number of outstanding shares of Series A-2 Stock (or such other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the Series A-2 Stock as to Liquidation) then owned by each such holder thereof until such holders are satisfied in full, and then to the holders of the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock pro rata with respect to such Series A-3, Stock Series A-5 Stock and Series A-6 Stock (and any other class or series of capital stock that is junior to the Series A-2 Stock but senior to or on parity with the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock as to Liquidation), based upon the number of outstanding shares of Series A-3 Stock, Series A-5 Stock and Series A-6 Stock <(or such other class or series of capital stock that is junior to the Series A-2 Stock but senior to or on parity with the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock as to Liquidation) then owned by each holder thereof, and then to the Series A-4 Stock (and any other class or series of capital stock that is junior to the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock but senior to or on parity with the Series A-4 Stock as to Liquidation), pro rata with respect to such Series A-4 Stock (or such other class or series of capital stock that is senior to or on parity with the Series A-4 Stock as to Liquidation) based upon the number of outstanding shares of Series A-4 Stock (or such other class or series of capital stock that is that is junior to the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock but senior to or on parity with the Series A-4 Stock as to Liquidation) then owned by each such holder thereof until such holders are satisfied in full.

(iv) On and after any Special Liquidation Date, all rights in respect of the shares of Preferred Stock to be redeemed shall cease and terminate except the right to receive the applicable Special Liquidation Price as provided herein, and such shares of Preferred Stock shall no longer be deemed to be outstanding, whether or not the certificates representing such shares of Preferred Stock have been received by the Corporation; provided, however, that, if the Corporation defaults in the payment of the Special Liquidation Price with respect to any Preferred Stock, the rights of the holder(s) thereof with respect to such shares of Preferred Stock shall continue until the Corporation cures such default.

(v) Anything contained herein to the contrary notwithstanding, all or any of the provisions of this Section 4(i) may be waived by the Senior Majority, by delivery of written notice of waiver to the Corporation prior to the closing of any Event of Sale.

(vi) Any notice required to be given to the holders of shares of Preferred Stock pursuant to Section 7(g) hereof in connection with an Event of Sale shall include a statement by the Corporation of (A) the Special Liquidation Price which each Preferred Stockholder shall be entitled to receive upon the occurrence of a Special Liquidation under this Section 4(i) and (B) the extent to which the Corporation will, if at all, be legally prohibited from paying each holder of Preferred Stock the Special Liquidation Price.

In any such vote, each share of Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share of Preferred Stock is then convertible, rounded up to the nearest one-tenth of a share, but not including any shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock.

The number of directors constituting the entire membership of the Board of Directors of the Corporation shall be set by the Board of Directors pursuant to the By-Laws of the Corporation.

(d) A vacancy in the directorships elected by the Series A-1 Stockholders, the G3 Holders or the MPM Holder pursuant to Section 6(b), may be filled by a vote at a meeting called in accordance with the by-laws of the Corporation or written consent in lieu of such meeting of the applicable holders of Preferred Stock, respectively, or by the remaining directors as provided in the Corporation’s By-Laws.

(c) If a Preferred Stockholder shall surrender more than one share of the same class of Preferred Stock for conversion at any one time, then the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Preferred Stock so surrendered.

(d) No fractional shares of Common Stock shall be issued upon conversion of Preferred Stock. The Corporation shall instead pay a cash adjustment for any such fractional interest in an amount equal to the Current Market Price thereof on the Conversion Date, as determined in accordance with Section 7(e)(vi) hereof.

(i) Subject to Section 7(e)(ii) and 7(e)(x) below, if the Corporation shall, at any time or from time to time after the Series A-1 Original Issuance Date, issue or sell any shares of Common Stock (which term, for purposes of this Section 7(e)(i), including all subsections thereof, shall be deemed to include all other securities convertible into, or exchangeable or exercisable for, shares of Common Stock (including, but not limited to, Preferred Stock) or options to purchase or other rights to subscribe for such convertible or exchangeable securities, in each case other than Excluded Stock (as defined in Section 7(e)(ii)

below), for a consideration per share less than the Series A-1 Conversion Price in effect immediately prior to the issuance of such Common Stock or other securities (a “Dilutive Issuance”), then (X) the Conversion Price of the Series A-1 Stock (the “Series A-1 Conversion Price”) in effect immediately prior to each such Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series A-1 Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series A-1 Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of additional stock so issued, (Y) the Conversion Price for the Series A-2 Stock (the “Series A-2 Conversion Price”) in effect immediately prior to each such Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series A-2 Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series A-2 Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of additional stock so issued, and (Z) the Conversion Price for the Series A-3 Stock (the “Series A-3 Conversion Price”) in effect immediately prior to each such Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series A-3 Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series A-3 Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of additional stock so issued. For purposes of this Section 7(e)(i), the number of shares of Common Stock deemed issuable upon conversion of such outstanding shares of Existing Preferred Stock shall be determined without giving effect to

any adjustments to the applicable Conversion Price resulting from the Dilutive Issuance that is the subject of this calculation.

b. In the case of the issuance of Common Stock for a consideration in whole or in part in property other than cash, the value of such property other than cash shall be deemed to be the fair market value of such property as determined in good faith by the Board of Directors, irrespective of any accounting treatment; provided, however, that such fair market value of such property as determined by the Board of Directors shall not exceed the aggregate Current Market Price (as defined in Section 7(e)(viii) hereof) of the shares of Common Stock or such other securities being issued, less any cash consideration paid for such shares, determined as provided in Section 7(e)(i)(a) hereof and less any other consideration received by the Corporation for such shares, determined as set forth in Section 7(e)(i)(c) hereof.

d. In the case of the issuance of options or other rights to purchase or subscribe for Common Stock or the issuance of securities by their terms convertible into or exchangeable or exercisable for Common Stock or options to purchase or other rights to subscribe for such convertible or exchangeable or exercisable securities:

i. the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections 7(e)(i)(a), (b) and (c) hereof), if any, received by the Corporation upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby (the consideration in each case to be determined in the manner provided in Sections 7(e)(i)(a), (b) and (c) hereof);

ii. the aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange for, any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in Sections 7(e)(i)(a), (b) and (c) hereof);

iii. if there is any change (whether automatic pursuant to the terms contained therein or as a result of the amendment of such terms) in the exercise price of, or number of shares deliverable upon exercise of, any such options or rights or upon the conversion or exchange of any such convertible or exchangeable securities (other than a change resulting from the original antidilution provisions thereof in place at the time of issuance of such security), then the applicable Conversion Price shall automatically be readjusted in proportion to such change (notwithstanding the foregoing, no adjustment pursuant to this clause shall have the effect of increasing the applicable Conversion Price to an amount which exceeds the lower of (i) the applicable Conversion Price on the original adjustment date, or (ii) the applicable Conversion Price that would have resulted from any Dilutive Issuances between the original adjustment date and such readjustment date);

iv. upon the expiration of any such options or rights or the termination of any such rights to convert or exchange such convertible or exchangeable securities (or in the event that the change that precipitated an adjustment pursuant to Section 7(e)(i)(d)(iii) hereof is reversed or terminated, or expires), then the applicable Conversion Price shall be automatically readjusted to the applicable Conversion Price that would have been obtained had such options, rights or convertible or exchangeable securities not been issued; and

v. if the terms of any option or convertible security (excluding options or convertible securities which, upon exercise, conversion or exchange thereof, would entitle the holder thereof to receive shares of Common Stock which are Excluded Stock), the issuance of which was not a Dilutive Issuance, are revised after the Series A-1 Original Issuance Date (either automatically pursuant the provisions contained therein or as a result of an amendment to such terms) to provide for either (1) any increase in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such option or convertible security or (2) any decrease in the consideration payable to the Corporation upon such exercise, conversion or exchange, then such option or convertible security, as so amended, and the shares of Common Stock subject thereto shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(iii) If the number of shares of Common Stock outstanding at any time after the Series A-1 Original Issuance Date (as defined in Section 8) is increased by a stock dividend payable in shares of Common Stock or by a subdivision or split-up of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such stock dividend, subdivision or split-up, the applicable Conversion Price shall be appropriately decreased in the form of a Proportional Adjustment (as defined in Section 8) so that the number of shares of Common Stock issuable on conversion of each share of Preferred Stock shall be increased in proportion to such increase in outstanding shares.

(iv) If the number of shares of Common Stock outstanding at any time after the Series A-1 Original Issuance Date is decreased by a combination of the outstanding shares of Common Stock (other than pursuant to the Reverse Split), then, following the record date for such combination, the applicable Conversion Price shall be appropriately increased in the form of a Proportional Adjustment so that the number of shares of Common Stock issuable on conversion of each share of Preferred Stock shall be decreased in proportion to such decrease in outstanding shares.

(vi) Subject to the provisions of Section 4(i) above, in the event, at any time after the Series A-1 Original Issuance Date, of any capital reorganization, or any reclassification of the capital stock of the Corporation (other than pursuant to the Reverse Split, other than as contemplated under this Certificate and the Series A-1 Purchase Agreement and other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or the consolidation or merger of the Corporation with or into another person (other than pursuant to the Merger Agreement and other than a consolidation or merger in which the Corporation is the continuing corporation and which does not result in any change in the powers, designations, preferences and rights, or the qualifications, limitations or restrictions, if any, of the capital stock of the Corporation) or of the sale or other disposition of all or substantially all the properties and assets of the Corporation in their entirety to any other person (any such transaction, an “Extraordinary Transaction”), then the Corporation shall provide appropriate adjustment in the form of a Proportional Adjustment to the applicable Conversion Price with respect to each share of Preferred Stock outstanding after the effectiveness of such Extraordinary Transaction such that each share of Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation, or of the corporation resulting from or surviving such Extraordinary Transaction, that a holder of the number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such share of Preferred Stock would have been entitled to receive upon such Extraordinary Transaction.

a. If the Common Stock is listed or admitted for trading on a national securities exchange, then the closing price for each day shall be the last reported sales price regular way or, in case no such reported sales took place on such day, the average of the last reported bid and asked prices regular way, in either case on the principal national securities exchange on which the Common Stock is listed or admitted to trading.

b.

c. If the Common Stock is not traded in such manner that the quotations referred to in this Section 7(e)(viii) are available for the period required hereunder, then the Current Market Price shall be the fair market value of such share, as determined in good faith by a majority of the entire Board of Directors.

(ix) In any case in which the provisions of this Section 7(e) shall require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of such event (A) issuing to the holder of any shares of Preferred Stock converted after such record date and before the occurrence of such event the additional shares of capital stock issuable upon such conversion by reason of the adjustment required by such event over and above the shares of capital stock issuable upon such conversion before giving effect to such adjustment, and (B) paying to such holder any cash amounts in lieu of fractional shares pursuant to Section 7(d) hereof; provided, however, that the Corporation shall deliver to such holder a due xxxx or other appropriate instrument evidencing such holder’s right to receive such additional shares and such cash upon the occurrence of the event requiring such adjustment.

(x) If a state of facts shall occur that, without being specifically controlled by the provisions of this Section 7, would not fairly protect the conversion rights of the holders of the Preferred Stock in accordance with the essential intent and principles of such provisions, then the Board of Directors shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such conversion rights.

(f) Whenever the applicable Conversion Price shall be adjusted as provided in Section 7(e) hereof, the Corporation shall forthwith file and keep on record at the office of the Secretary of the Corporation and at the office of its transfer agent or at such other place as may be designated by the Corporation, a statement, signed by both its President or Chief Executive Officer and its Treasurer or Chief Financial Officer, showing in detail the facts requiring such adjustment and the applicable Conversion Price that shall be in effect after such adjustment. The Corporation shall also cause a copy of such statement to be sent by first-class, certified mail, return receipt

requested, postage prepaid, to each Preferred Stockholder at such holder’s address appearing on the Corporation’s records. Where appropriate, such copy shall be given in advance of any such adjustment and shall be included as part of a notice required to be mailed under the provisions of Section 7(g) hereof.

(g) In the event the Corporation shall propose to take any action of the types described in Section 7(e)(i), (iii), (iv) or (v) hereof, or any other Event of Sale, other then the transactions contemplated by the Series A-1 Purchase Agreement and the Merger Agreement, the Corporation shall give notice to each Preferred Stockholder in the manner set forth in Section 7(f) hereof, which notice shall specify the record date, if any, with respect to any such action and the date on which such action is to take place.

In the case of any action (other than any action contemplated or required by the Series A-1 Purchase Agreement or Merger Agreement) that would require the fixing of a record date, such notice shall be given at least 20 days prior to the record date so fixed, and in the case of any other action, such notice shall be given at least 30 days prior to the taking of such proposed action.

(h) The Corporation shall pay all documentary, stamp or other transactional taxes attributable to the issuance or delivery of shares of capital stock of the Corporation upon conversion of any shares of Preferred Stock; provided, however, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the Preferred Stockholder in respect of which such shares of Preferred Stock are being issued.

(i) The Corporation shall reserve out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the Preferred Stock, sufficient shares of Common Stock to provide for the conversion of all outstanding shares of Preferred Stock.

(j) All shares of Common Stock which may be issued in connection with the conversion provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and nonassessable, not subject to any preemptive or similar rights, and free from all taxes, liens or charges with respect thereto created or imposed by the Corporation.

Upon receipt of such notice, each holder of such shares of Preferred Stock shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Preferred Stock so converted, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the time of the Special Mandatory Conversion (notwithstanding the failure of the holder or holders thereof to surrender the certificates for such shares at or prior to such time), except only the rights of the holders thereof, upon surrender of their certificate or certificates therefor (or lost certificate affidavit and agreement), to receive the items provided for in the next sentence of this Section 10(b). As soon as practicable after the Special Mandatory Conversion and the surrender of the certificate or certificates (or lost certificate affidavit and agreement) for Preferred Stock so converted, the Corporation shall issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof, together with cash as provided in Section 7(d) in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Preferred Stock converted, and a new certificate for the number of shares, if any, of Preferred Stock represented by such surrendered certificate and not converted pursuant to Section 10(a). Such converted Preferred Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may

thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Preferred Stock accordingly.

(c) Duration of Section. This Section 10 and the rights and obligations of the parties hereunder shall automatically terminate on the consummation of a Liquidation or an Event of Sale.

3. The undersigned further certifies that the authorized number of shares of Preferred Stock is Ten Million (10,000,000) and that the authorized number of shares of the Series A-1 Stock, none of which has been issued, is One Million (1,000,000), that the authorized number of shares of the Series A-2 Stock, none of which has been issued, is Nine Hundred Eighty-three Thousand Two Hundred Thirteen (983,213), that the authorized number of shares of the Series A-3 Stock, none of which has been issued, is One Hundred Forty-two Thousand Two Hundred Thirty (142,230), that the authorized number of shares of the Series A-4 Stock, none of which has been issued, is Four Thousand (4,000), that the authorized number of shares of the Series A-5 Stock, none of which has been issued, is Seven Thousand (7,000), and that the authorized number of shares of the Series A-6 Stock, none of which has been issued, is Eight Hundred Thousand (800,000).

IMPORTANT TAX INFORMATION

Circular 230 Disclosure: The statements contained herein were not intended or written to be used, and cannot be used, for the purpose of avoiding any federal tax penalties. Because the statements in this document might be viewed as a “marketed opinion” under the “Circular 230” rules set forth in applicable Treasury Regulations, holders are hereby informed that such statements were written to support the “promotion or marketing” of the matters described herein. Holders should seek advice from their independent tax advisers regarding the tax consequences of these matters based on their particular circumstances.

Under United States federal income tax law, a holder may be subject to backup withholding of 28% of the gross proceeds received by such holder from the Parent. In order to avoid such backup withholding, a U.S. holder must provide the Parent with such holder’s correct taxpayer identification number (“TIN”) and certify that such holder is not subject to such backup withholding by completing the Substitute Form W-9 provided herewith. If such holder is an individual, the TIN is his or her social security number. Failure to provide a holder’s TIN on the Substitute Form W-9, if applicable, may subject the holder (or other payee) to a $50 penalty imposed by the Internal Revenue Service (“IRS”). More serious penalties may be imposed for providing false information which, if willfully done, may result in fines and/or imprisonment. The depositary may withhold 28% on all payment of the Merger Consideration if the TIN is not certified on its records. In order for a foreign holder to qualify as an exempt recipient, that holder should submit an appropriate Form W-8 (generally, an IRS Form W-8BEN), signed under penalties of perjury, attesting to that holder’s exempt status. An IRS form W-8BEN has been included as part of these materials. Failure to provide the information on the appropriate form may subject holders to 28% United States federal income tax withholding on the payment of the Merger Consideration. Backup withholding is not an additional tax. Rather, the tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained by timely filing a tax return with the IRS. The Parent cannot refund amounts withheld by reason of backup withholding.

The IRS may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism. You must provide your TIN whether or not you are required to file a tax return. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to a payer. Certain penalties may also apply.

Penalties

(1) Failure to Furnish Taxpayer Identification Number. – If you fail to furnish your taxpayer identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for False Information With Respect to Withholding. – If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

(3) Criminal Penalty for Falsifying Information. – Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

This Agreement (the “Agreement”) is made as of April 25, 2011, by and between MPM Acquisition Corp., a Delaware corporation (the “Issuer”), and MPM Asset Management LLC, a Delaware limited liability company (the “Seller”).

W I T N E S S E T H:

WHEREAS, the Seller is the owner of five million (5,000,000) shares of the Issuer’s common stock, par value $0.0001 per share (“Common Stock”), and

WHEREAS, the Seller desires to sell to the Issuer, and the Issuer desires to re-purchase from the Seller, five million (5,000,000) shares of Common Stock (the “Shares”), on and subject to the terms of this Agreement;

WHEREFORE, the parties hereto hereby agree as follows:

1. Sale of the Shares. Subject to the terms and conditions of this Agreement, and in reliance upon the representations, warranties, covenants and agreements contained in this Agreement, the Seller shall sell the Shares to the Issuer, and the Issuer shall re-purchase the Shares from the Seller, for a purchase price equal to an aggregate sum of fifty thousand dollars ($50,000) (the “Purchase Price”).

2. Closing.

(a) The purchase and sale of the Shares shall take place at a closing (the “Closing”), to occur concurrently with the completion of the merger transaction (the “Merger”) contemplated by that certain Agreement and Plan of Merger of even date herewith (the “Merger Agreement”) among the Issuer, Radius Health, Inc. and RHI Merger Corp. The parties hereto shall have no obligation to complete the Closing in the event the Merger is not consummated.

(b) At the Closing:

(i) The Seller shall deliver to the Issuer certificates representing the Shares, duly endorsed in form for transfer to the Issuer.

(ii) The Issuer shall pay to the Seller the Purchase Price for the Shares.

(iii) At, and at any time after, the Closing, the parties shall duly execute, acknowledge and deliver all such further assignments, conveyances, instruments and documents, and shall take such other action consistent with the terms of this Agreement to carry out the transactions contemplated by this Agreement.

3. Representations and Warranties of the Issuer. The Issuer hereby makes the following representations and warranties to the Seller:

(a) The Issuer is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. The Issuer has the corporate power to own its properties and to carry on its business as now being conducted and is duly qualified to do business and is in good standing in each jurisdiction in which the failure to be so qualified and in good standing would have a material adverse effect on the Issuer. The Issuer is not in violation of any of the provisions of its certificate of incorporation or by-laws. No consent, approval or agreement of any individual or entity is required to be obtained by the Issuer in connection with the execution and performance by the Issuer of this Agreement or the execution and performance by the Issuer of any agreements, instruments or other obligations entered into in connection with this Agreement.

(b) The Issuer has authorized capital stock consisting of 100,000,000 shares of Issuer Common Stock, and 10,000,000 shares of preferred stock, par value $0.0001 per share (the “Preferred Stock”), of which 5,000,000 shares of Common Stock, consisting of the Shares, and no shares of Preferred Stock, are the only shares presently issued and outstanding.

(c) There is no private or governmental action, suit, proceeding, claim, arbitration or investigation pending before any agency, court or tribunal, foreign or domestic, or, to the Issuer’s knowledge, threatened against the Issuer or any of its properties or any of its officers or directors (in their capacities as such). There is no judgment, decree or order against the Issuer that could prevent, enjoin, alter or delay any of the transactions contemplated by this Agreement. The term “Issuer’s knowledge” shall mean and include actual knowledge of the Seller or of any member, director or officer of the Issuer.

(d) There are no material claims, actions, suits, proceedings, inquiries, labor disputes or investigations (whether or not purportedly on behalf of the Issuer) pending or, to the Issuer’s knowledge, threatened against the Issuer or any of its assets, at law or in equity or by or before any governmental entity or in arbitration or mediation. No bankruptcy, receivership or debtor relief proceedings are pending or, to the best of the Issuer’s knowledge, threatened against the Issuer.

(e) The Issuer has complied with, is not in violation of, and has not received any notices of violation with respect to, any federal, state, local or foreign Law, judgment, decree, injunction or order, applicable to it, the conduct of its business, or the ownership or operation of its business. References in this Agreement to “Laws” shall refer to any laws, rules or regulations of any federal, state or local government or any governmental or quasi-governmental agency, bureau, commission, instrumentality or judicial body (including, without limitation, any federal or state securities law, regulation, rule or administrative order).

(f) The Issuer has properly filed all tax returns required to be filed and has paid all taxes shown thereon to be due. To the Issuer’s knowledge, all tax returns previously filed are true and correct in all material respects.

(g) The Issuer has no outstanding liabilities or obligations to any party except as reflected on the Issuer’s Form 10-K for the year ended December 31, 2010, other than charges since such date similar to those incurred in past periods and consistent with past practice, all of which will be discharged prior to or at the Closing so that, at the Closing, the Issuer will have no direct, contingent or other obligations of any kind or any commitment or contractual obligations of any kind and description.

(h) All of the business and financial transactions of the Issuer have been fully and properly reflected in the books and records of the Issuer in all material respects and in accordance with generally accepted accounting principles consistently applied.

(i) The Issuer is current with its reporting obligations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). None of the Issuer’s filings made pursuant to the Exchange Act (collectively, the “Issuer SEC Documents”) contain any misstatements of material fact or omit to state a material fact necessary to make the statements made therein not misleading. The Issuer SEC Documents, as of their respective dates, complied in all material respects with the requirements of the Exchange Act, and the rules and regulations of the Commission thereunder, and are available on the Commission’s XXXXX system. There has not occurred any material adverse change, or any development involving a prospective material adverse change, in the condition, financial or otherwise, or in the earnings, business or operations of the Issuer, from that set forth in the Issuer’s Annual Report on Form 10-K for the year ended December 31, 2010.

(j) As of the Closing, the Issuer will have assets sufficient to satisfy its payment obligations set forth in Section 1 hereof and the redemption contemplated hereby shall be permitted by the Delaware General Corporation Law. The execution and delivery of this Agreement by the Issuer and the Seller and the consummation of the transactions contemplated by this Agreement will not result in any violation of the Issuer’s certificate of incorporation or by-laws or any applicable Law, including without limitation, the Delaware General Corporation Law.

(k) All representations, covenants and warranties of the Issuer contained in this Agreement shall be true and correct on and as of the Closing Date with the same effect as though the same had been made on and as of such date.

The Seller is not in violation of any of the provisions of its constitutive or governing documents.

of this Agreement or the execution and performance by the Issuer of any agreements, instruments or other obligations entered into in connection with this Agreement.

Exhibit E

INDEMNIFICATION AGREEMENT

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of May , 2011 between Radius Health, Inc., a Delaware corporation (the “Company”), and (“Indemnitee”).

WITNESSETH THAT:

WHEREAS, highly competent persons have become more reluctant to serve corporations as directors or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation;

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Bylaws and Certificate of Incorporation of the Company require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (“DGCL”). The Bylaws, Certificate of Incorporation and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect to indemnification;

WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such persons;

WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future;

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified;

WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws and Certificate of Incorporation of the Company and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee

thereunder; and

WHEREAS, Indemnitee does not regard the protection available under the Company’s Bylaws and Certificate of Incorporation and insurance as adequate in the present circumstances, and may not be willing to serve as a director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified; and

NOW, THEREFORE, in consideration of Indemnitee’s agreement to serve as a director from and after the date hereof, the parties hereto agree as follows:

1. Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof:

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section l(a) if, by reason of his Corporate Status (as hereinafter defined), the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as hereinafter defined) other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by him, or on his behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful.

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this Section 1(b) if, by reason of his Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such indemnification may be made.

(c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the maximum extent permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than

all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

2. Additional Indemnity. In addition to, and without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf if, by reason of his Corporate Status, he is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful.

3. Contribution.

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee.

(b) Without diminishing or impairing the obligations of the Company set forth in the preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which the Law may require to be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who

are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is active or passive.

(c) The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee.

(d) To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s).

4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a witness, or is made (or asked to) respond to discovery requests, in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith.

5. Advancement of Expenses. Notwithstanding any other provision of this Agreement, the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free.

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement:

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine

whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board of Directors in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially prejudices the interests of the Company.

(b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the board: (1) by a majority vote of the disinterested directors, even though less than a quorum, (2) by a committee of disinterested directors designated by a majority vote of the disinterested directors, even though less than a quorum, (3) if there are no disinterested directors or if the disinterested directors so direct, by independent legal counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to the Indemnitee, or (4) if so directed by the Board of Directors, by the stockholders of the Company. For purposes hereof, disinterested directors are those members of the board of directors of the Company who are not parties to the action, suit or proceeding in respect of which indemnification is sought by Indemnitee.

(c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board of Directors. Indemnitee may, within 10 days after such written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 13 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any objection which shall have been made by the Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed.

(d) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to

overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct.

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise (as hereinafter defined) in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

(f) If the person, persons or entity empowered or selected under Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board of Directors or the Disinterested Directors, if appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat.

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and

which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board of Directors or stockholder of the Company shall act reasonably and in good faith in making a determination regarding the Indemnitee’s entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

(i) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful.

7. Remedies of Indemnitee.

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant to Section 6(b) of this Agreement within 90 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within ten (10) days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 7(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication.

(b) In the event that a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo

trial on the merits, and Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b).

(c) If a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law.

(d) In the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of his rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company shall pay on his behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably incurred by him in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery.

(e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be.

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding.

8. Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation.

(a) The rights of indemnification as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders, a resolution of directors or otherwise, of the Company. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Certificate of Incorporation, Bylaws and this Agreement, it is the

intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy.

(b) To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees, or agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies.

(c) In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

(d) Except as provided in paragraph (c) above, the Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

(e) Except as provided in paragraph (c) above, the Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee:

(a) for which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or

(b) for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section

16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law; or

(c) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board of Directors of the Company authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law.

10. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue during the period Indemnitee is an officer or director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and shall continue thereafter so long as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of his Corporate Status, whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives.

11. Security. To the extent requested by Indemnitee and approved by the Board of Directors of the Company, the Company may at any time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or released without the prior written consent of the Indemnitee.

12. Enforcement.

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it hereby in order to induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of the Company.

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof.

13. Definitions. For purposes of this Agreement:

(a) “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent or fiduciary of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person is or was serving at the express written request of the Company.

(b) “Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding in respect of which indemnification is sought by Indemnitee.

(c) “Enterprise” shall mean the Company and any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that Indemnitee is or was serving at the express written request of the Company as a director, officer, employee, agent or fiduciary.

(d) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs, fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding, or responding to, or objecting to, a request to provide discovery in any Proceeding. Expenses also shall include Expenses incurred in connection with any appeal resulting from any Proceeding and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement, including without limitation the premium, security for, and other costs relating to any cost bond, supersede as bond, or other appeal bond or its equivalent. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee.

(e) “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto.

(f) “Proceeding” includes any threatened, pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or otherwise and whether civil, criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of the fact that Indemnitee is or was an officer or director of the Company, by reason of any action taken by him or of any inaction on his part while acting as an officer or director of the Company, or by reason of the fact that he is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other Enterprise; in each case whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement; including one pending on or before the date of this Agreement, but excluding

one initiated by an Indemnitee pursuant to Section 7 of this Agreement to enforce his rights under this Agreement.

14. Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In the event any provision hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict.

15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

16. Notice By Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay materially prejudices the Company.

17. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.
