AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION (this “Agreement”) is made and entered into as of April 18, 2017, by and among NIVALIS THERAPEUTICS, INC., a Delaware corporation (“Nautilus”), NAUTILUS MERGER SUB, INC., a Delaware corporation and wholly owned subsidiary of Nautilus (“Merger Sub”), and ALPINE IMMUNE SCIENCES, INC., a Delaware corporation (the “Company”). Certain capitalized terms used in this Agreement are defined in Exhibit A.

RECITALS

A. Nautilus and the Company intend to effect a merger of Merger Sub with and into the Company (the “Merger”) in accordance with this Agreement and the DGCL. Upon consummation of the Merger, Merger Sub will cease to exist and the Company will become a wholly owned subsidiary of Nautilus.

B. The Parties intend that the Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

C. The Nautilus Board has (i) determined that the Contemplated Transactions are fair to, advisable and in the best interests of Nautilus and its stockholders, (ii) approved and declared advisable this Agreement and the Contemplated Transactions, including the issuance of shares of Nautilus Common Stock to the stockholders of the Company pursuant to the terms of this Agreement and (iii) determined to recommend, upon the terms and subject to the conditions set forth in this Agreement, that the stockholders of Nautilus vote to approve this Agreement and the Contemplated Transactions, including the issuance of shares of Nautilus Common Stock to the stockholders of the Company pursuant to the terms of this Agreement and, if deemed necessary by the Parties, an amendment to Nautilus’ certificate of incorporation to effect the Nautilus Reverse Stock Split.

D. The Merger Sub Board has (i) determined that the Contemplated Transactions are fair to, advisable, and in the best interests of Merger Sub and its sole stockholder, (ii) approved and declared advisable this Agreement and the Contemplated Transactions and (iii) determined to recommend, upon the terms and subject to the conditions set forth in this Agreement, that the stockholder of Merger Sub vote to adopt this Agreement and thereby approve the Contemplated Transactions.

E. The Company Board has (i) determined that the Contemplated Transactions are fair to, advisable and in the best interests of the Company and its stockholders, (ii) approved and declared advisable this Agreement and the Contemplated Transactions and (iii) determined to recommend, upon the terms and subject to the conditions set forth in this Agreement, that the stockholders of the Company vote to adopt this Agreement and thereby approve the Contemplated Transactions.

F. Concurrently with the execution and delivery of this Agreement and as a condition and inducement to the Company’s willingness to enter into this Agreement, the officers, directors and stockholders of Nautilus listed on Section A of the Nautilus Disclosure Schedule (solely in their capacity as stockholders of Nautilus) are executing support agreements

in favor of the Company in substantially the form attached hereto as Exhibit B (the “Nautilus Stockholder Support Agreement”), pursuant to which such Persons have, subject to the terms and conditions set forth therein, agreed to vote all of their shares of capital stock of Nautilus in favor of the approval of this Agreement and thereby approve the Contemplated Transactions and against any competing proposals.

G. Concurrently with the execution and delivery of this Agreement and as a condition and inducement to Nautilus’ willingness to enter into this Agreement, the officers, directors and 5% or greater stockholders (together with their Affiliates) of the Company listed on Section A of the Company Disclosure Schedule (solely in their capacity as stockholders of the Company) are executing support agreements in favor of Nautilus in substantially the form attached hereto as Exhibit C (the “Company Stockholder Support Agreement”), pursuant to which such Persons have, subject to the terms and conditions set forth therein, agreed to vote all of their shares of Company Capital Stock in favor of the adoption of this Agreement and thereby approve the Contemplated Transactions and against any competing proposals.

H. It is expected that the issuance of shares of Nautilus Common Stock to the stockholders of the Company pursuant to the Merger will result in a change of control of Nautilus.

I. It is expected that within two Business Days after the Registration Statement is declared effective under the Securities Act, the holders of shares of Company Capital Stock sufficient to adopt and approve this Agreement and the Merger as required under the DGCL and the Company’s certificate of incorporation and bylaws will execute and deliver an action by written consent adopting this Agreement in a form reasonably acceptable to Nautilus, in order to obtain the Required Company Stockholder Vote (each, a “Company Stockholder Written Consent” and collectively, the “Company Stockholder Written Consents”).

J. Immediately prior to the execution and delivery of this Agreement, and as a condition of the willingness of Nautilus to enter into this Agreement, certain investors have executed the Subscription Agreement, in the form attached hereto as Exhibit D, with the Company, pursuant to which such investors have agreed to purchase certain shares of Company Capital Stock prior to the Closing in connection with the Company Pre-Closing Financing.

AGREEMENT

The Parties, intending to be legally bound, agree as follows:

Section 1. DESCRIPTION OF TRANSACTION

1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, Merger Sub shall be merged with and into the Company, and the separate existence of Merger Sub shall cease. The Company will continue as the surviving corporation in the Merger (the “Surviving Corporation”).

1.2 Effects of the Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the DGCL. As a result of the Merger, the Company will become a wholly owned subsidiary of Nautilus.

1.3 Closing; Effective Time. Unless this Agreement is earlier terminated pursuant to the provisions of Section 9.1, and subject to the satisfaction or waiver of the conditions set forth in Sections 6, 7 and 8, the consummation of the Merger (the “Closing”) shall take place at the offices of Xxxxxx & Xxxxxxx LLP, 000 Xxxxx Xxxxx, Xxxxx Xxxx, Xxxxxxxxxx 00000, as promptly as practicable (but in no event later than the second Business Day following the satisfaction or waiver of the last to be satisfied or waived of the conditions set forth in Sections 6, 7 and 8, other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of each of such conditions), or at such other time, date and place as Nautilus and the Company may mutually agree in writing. The date on which the Closing actually takes place is referred to as the “Closing Date.” At the Closing, the Parties shall cause the Merger to be consummated by executing and filing with the Secretary of State of the State of Delaware a certificate of merger with respect to the Merger, satisfying the applicable requirements of the DGCL and in a form reasonably acceptable to Nautilus and the Company (the “Certificate of Merger”). The Merger shall become effective at the time of the filing of such Certificate of Merger with the Secretary of State of the State of Delaware or at such later time as may be specified in such Certificate of Merger with the consent of Nautilus and the Company (the time as of which the Merger becomes effective being referred to as the “Effective Time”).

1.4 Certificate of Incorporation and Bylaws; Directors and Officers. At the Effective Time:

(a) the certificate of incorporation of the Surviving Corporation shall be amended and restated in its entirety to read identically to the certificate of incorporation of Merger Sub as in effect immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such certificate of incorporation;

(b) the certificate of incorporation of Nautilus shall be identical to the certificate of incorporation of Nautilus immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such certificate of incorporation; provided, however, that at the Effective Time, Nautilus shall file an amendment to its certificate of incorporation to (i) change the name of Nautilus to “Alpine Immune Sciences, Inc.,” and (ii) effect the Nautilus Reverse Stock Split, such amendment to be in the form attached hereto as Exhibit E, with such changes as are mutually agreed by Nautilus and the Company (the “Nautilus Charter Amendment”);

(c) the bylaws of the Surviving Corporation shall be identical to the bylaws of Merger Sub as in effect immediately prior to the Effective Time, until thereafter amended as provided by the DGCL and such bylaws;

(d) the directors and officers of Nautilus, each to hold office in accordance with the certificate of incorporation and bylaws of Nautilus, shall be as set forth in Section 5.14; and

(e) the directors and officers of the Surviving Corporation, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation, shall

be the directors and officers of Nautilus as set forth in Section 5.14, after giving effect to the provisions of Section 5.14.

1.5 Conversion of Shares.

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Nautilus, Merger Sub, the Company or any stockholder of the Company or Nautilus:

(i) any shares of Company Capital Stock held as treasury stock or held or owned by the Company or Merger Sub, or any Subsidiary of the Company immediately prior to the Effective Time shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor; and

(ii) subject to Section 1.5(c), each share of Company Capital Stock (including any shares of Company Capital Stock issued pursuant to the Company Pre-Closing Financing) outstanding immediately prior to the Effective Time (excluding shares to be canceled pursuant to Section 1.5(a)(i) and excluding Dissenting Shares) shall be converted solely into the right to receive a number of shares of Nautilus Common Stock equal to the Exchange Ratio (the “Merger Consideration”).

(b) If any shares of Company Capital Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option or a risk of forfeiture under any applicable restricted stock purchase agreement or other similar agreement with the Company, then the shares of Nautilus Common Stock issued in exchange for such shares of Company Capital Stock will to the same extent be unvested and subject to the same repurchase option or risk of forfeiture, and such shares of Nautilus Common Stock shall accordingly be marked with appropriate legends. The Company shall take all actions that may be necessary to ensure that, from and after the Effective Time, Nautilus is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other agreement.

(c) No fractional shares of Nautilus Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Company Capital Stock who would otherwise be entitled to receive a fraction of a share of Nautilus Common Stock (after aggregating all fractional shares of Nautilus Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender by such holder of a letter of transmittal in accordance with Section 1.7 and any accompanying documents as required therein, be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the Nautilus Closing Price.

(d) All Company Options and Company Warrants outstanding immediately prior to the Effective Time under the Company Plan shall be treated in accordance with Section 5.5.

(e) Each share of common stock, $0.0001 par value per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and

exchanged for one validly issued, fully paid and nonassessable share of common stock, $0.0001 par value per share, of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall, as of the Effective Time, evidence ownership of such shares of common stock of the Surviving Corporation.

(f) If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Capital Stock or Nautilus Common Stock shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split (including the Nautilus Reverse Stock Split to the extent such split has not previously been taken into account in calculating the Exchange Ratio), combination or exchange of shares or other like change, the Exchange Ratio shall, to the extent necessary, be equitably adjusted to reflect such change to the extent necessary to provide the holders of Company Capital Stock and Nautilus Common Stock with the same economic effect as contemplated by this Agreement prior to such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or other like change; provided, however, that nothing herein will be construed to permit the Company or Nautilus to take any action with respect to Company Capital Stock or Nautilus Common Stock, respectively, that is prohibited or not expressly permitted by the terms of this Agreement.

1.6 Closing of the Company’s Transfer Books. At the Effective Time: (a) all shares of Company Capital Stock outstanding immediately prior to the Effective Time shall be treated in accordance with Section 1.5(a), and all holders of certificates representing shares of Company Capital Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company; and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Capital Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Capital Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Capital Stock outstanding immediately prior to the Effective Time (a “Company Stock Certificate”) is presented to the Exchange Agent or to the Surviving Corporation, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Sections 1.5 and 1.7.

1.7 Surrender of Certificates.

(a) On or prior to the Closing Date, Nautilus and the Company shall agree upon and select a reputable bank, transfer agent or trust company to act as exchange agent in the Merger (the “Exchange Agent”). At the Effective Time, Nautilus shall deposit with the Exchange Agent: (i) evidence of book-entry shares representing the Nautilus Common Stock issuable pursuant to Section 1.5(a) and (ii) cash sufficient to make payments in lieu of fractional shares in accordance with Section 1.5(c). The Nautilus Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares, are referred to collectively as the “Exchange Fund.”

(b) Promptly after the Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of shares of Company Capital Stock that were converted into the right to receive the Merger Consideration: (i) a letter of transmittal in

customary form and containing such provisions as Nautilus may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent); and (ii) instructions for effecting the surrender of Company Stock Certificates in exchange for book-entry shares of Nautilus Common Stock. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Nautilus: (A) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor book-entry shares representing the Merger Consideration (in a number of whole shares of Nautilus Common Stock) that such holder has the right to receive pursuant to the provisions of Section 1.5(a) (and cash in lieu of any fractional share of Nautilus Common Stock pursuant to the provisions of Section 1.5(c)); and (B) the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.7(b), each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive book-entry shares of Nautilus Common Stock representing the Merger Consideration (and cash in lieu of any fractional share of Nautilus Common Stock). If any Company Stock Certificate shall have been lost, stolen or destroyed, Nautilus may, in its discretion and as a condition precedent to the delivery of any shares of Nautilus Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an applicable affidavit with respect to such Company Stock Certificate and post a bond indemnifying Nautilus against any claim suffered by Nautilus related to the lost, stolen or destroyed Company Stock Certificate or any Nautilus Common Stock issued in exchange therefor as Nautilus may reasonably request.

(c) No dividends or other distributions declared or made with respect to Nautilus Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Nautilus Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate or provides an affidavit of loss or destruction in lieu thereof in accordance with this Section 1.7 (at which time such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar laws, to receive all such dividends and distributions, without interest).

(d) Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date that is 180 days after the Closing Date shall be delivered to Nautilus upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 1.7 shall thereafter look only to Nautilus for satisfaction of their claims for Nautilus Common Stock, cash in lieu of fractional shares of Nautilus Common Stock and any dividends or distributions with respect to shares of Nautilus Common Stock.

(e) Each of the Exchange Agent, Nautilus and the Surviving Corporation shall be entitled to deduct and withhold from any consideration deliverable pursuant to this Agreement to any holder of any Company Stock Certificate such amounts as are required to be deducted or withheld from such consideration under the Code or under any other applicable Law. To the extent such amounts are so deducted or withheld, and remitted to the appropriate taxing

authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f) No party to this Agreement shall be liable to any holder of any Company Stock Certificate or to any other Person with respect to any shares of Nautilus Common Stock (or dividends or distributions with respect thereto) or for any cash amounts delivered to any public official pursuant to any applicable abandoned property law, escheat law or similar Law.

1.8 Appraisal Rights.

(a) Notwithstanding any provision of this Agreement to the contrary, shares of Company Capital Stock that are outstanding immediately prior to the Effective Time and which are held by stockholders who have exercised and perfected appraisal rights for such shares of Company Capital Stock in accordance with the DGCL (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration described in Section 1.5 attributable to such Dissenting Shares. Such stockholders shall be entitled to receive payment of the appraised value of such shares of Company Capital Stock held by them in accordance with the DGCL, unless and until such stockholders fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL. All Dissenting Shares held by stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their right to appraisal of such shares of Company Capital Stock under the DGCL shall thereupon be deemed to be converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration attributable to such Dissenting Shares upon their surrender in the manner provided in Section 1.5.

(b) The Company shall give Nautilus prompt written notice of any demands by dissenting stockholders received by the Company, withdrawals of such demands and any other instruments served on the Company and any material correspondence received by the Company in connection with such demands. The Company shall not, without Nautilus’ prior written consent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

1.9 Further Action. If, at any time after the Effective Time, any further action is determined by the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of the Company, then the officers and directors of the Surviving Corporation shall be fully authorized, and shall use their and its commercially reasonable efforts (in the name of the Company, in the name of Merger Sub, in the name of the Surviving Corporation and otherwise) to take such action.

1.10 Tax Consequences. For United States federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of Section 368(a) of the Code. The Parties adopt this Agreement as a “plan of reorganization” within the meaning of Section 1.368-2(g) of the Treasury Regulations.

Section 2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Subject to Section 10.13(h), except as set forth in the written disclosure schedule delivered by the Company to Nautilus (the “Company Disclosure Schedule”), the Company represents and warrants to Nautilus and Merger Sub as follows:

2.1 Due Organization; Subsidiaries.

(a) Each of the Company and its Subsidiaries is a corporation or other legal entity duly incorporated or otherwise organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization and has all necessary power and authority: (i) to conduct its business in the manner in which its business is currently being conducted; (ii) to own or lease and use its property and assets in the manner in which its property and assets are currently owned or leased and used; and (iii) to perform its obligations under all Contracts by which it is bound.

(b) Each of the Company and its Subsidiaries is duly licensed and qualified to do business, and is in good standing (to the extent applicable in such jurisdiction), under the laws of all jurisdictions where the nature of its business requires such licensing or qualification other than in jurisdictions where the failure to be so qualified individually or in the aggregate would not be reasonably expected to have a Company Material Adverse Effect.

(c) The Company has no Subsidiaries, except for the Entities identified in Section 2.1(c) of the Company Disclosure Schedule; and neither the Company nor any of the Entities identified in Section 2.1(c) of the Company Disclosure Schedule owns any capital stock of, or any equity, ownership or profit sharing interest of any nature in, or controls directly or indirectly, any other Entity other than the Entities identified in Section 2.1(c) of the Company Disclosure Schedule. Neither the Company nor any of its Subsidiaries is or has otherwise been, directly or indirectly, a party to, member of or participant in any partnership, joint venture or similar business entity. Neither the Company nor any of its Subsidiaries has agreed or is obligated to make, or is bound by any Contract under which it may become obligated to make, any future investment in or capital contribution to any other Entity. Neither the Company nor any of its Subsidiaries has, at any time, been a general partner of, or has otherwise been liable for any of the debts or other obligations of, any general partnership, limited partnership or other Entity.

2.2 Organizational Documents. The Company has delivered to Nautilus accurate and complete copies of the Organizational Documents of the Company and each of its Subsidiaries. Neither the Company nor any of its Subsidiaries is in breach or violation of its Organizational Documents in any material respect.

2.3 Authority; Binding Nature of Agreement. The Company and each of its Subsidiaries have all necessary corporate power and authority to enter into and to perform its obligations under this Agreement and to consummate the Contemplated Transactions. The Company Board has (i) determined that the Contemplated Transactions are fair to, advisable and in the best interests of the Company and its stockholders, (ii) approved and declared advisable this Agreement and the Contemplated Transactions and (iii) determined to recommend, upon the terms and subject to the conditions set forth in this Agreement, that the stockholders of the Company vote to adopt this Agreement and thereby approve the Contemplated Transactions.

This Agreement has been duly executed and delivered by the Company and assuming the due authorization, execution and delivery by Nautilus and Merger Sub, constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to the Enforceability Exceptions. Prior to the execution of the Company Stockholder Support Agreements, the Company Board approved the Company Stockholder Support Agreements and the transactions contemplated thereby.

2.4 Vote Required. The affirmative vote (or written consent) of (a) the holders of a majority of the shares of Company Common Stock and Company Preferred Stock each outstanding on the record date for the Company Stockholder Written Consent and entitled to vote thereon, voting as a single class, and (b) the holders of a majority of the shares of Company Preferred Stock outstanding on the record date for the Company Stockholder Written Consent and entitled to vote thereon, voting as a separate class (collectively, the “Required Company Stockholder Vote”), is the only vote (or written consent) of the holders of any class or series of Company Capital Stock necessary to adopt and approve this Agreement and approve the Contemplated Transactions.

2.5 Non-Contravention; Consents. Subject to obtaining the Required Company Stockholder Vote and the filing of the Certificate of Merger required by the DGCL, neither (x) the execution, delivery or performance of this Agreement by the Company, nor (y) the consummation of the Contemplated Transactions, will directly or indirectly (with or without notice or lapse of time):

(a) contravene, conflict with or result in a violation of any of the provisions of the Company’s Organizational Documents;

(b) contravene, conflict with or result in a material violation of, or to the Knowledge of the Company give any Governmental Body or other Person the right to challenge the Contemplated Transactions or to exercise any material remedy or obtain any material relief under, any Law or any order, writ, injunction, judgment or decree to which the Company or its Subsidiaries, or any of the assets owned or used by the Company or its Subsidiaries, is subject, except as would not be material to the Company or its business;

(c) contravene, conflict with or result in a material violation of any of the terms or requirements of, or to the Knowledge of the Company, give any Governmental Body the right to revoke, withdraw, suspend, cancel, terminate or modify, any Governmental Authorization that is held by the Company or its Subsidiaries, except as would not be material to the Company or its business;

Such Party shall keep the other Party reasonably informed with respect to the status and terms of any such Acquisition Proposal or Acquisition Inquiry and any material modification or proposed material modification thereto.

No notification given to a Party pursuant to this Section 4.5 shall change, limit or otherwise affect any of the representations, warranties, covenants or obligations of the Party providing such notification or any of such Party’s Subsidiaries contained in this Agreement or the Company Disclosure Schedule or the Nautilus Disclosure Schedule, as appropriate, for purposes of Sections 6, 7 and 8, as applicable.

Each of the Parties shall use commercially reasonable efforts to cause the Proxy Statement to be mailed to Nautilus’ stockholders as promptly as practicable after the Registration Statement is declared effective under the Securities Act. Each Party shall promptly furnish to the other Party all information concerning such Party and such Party’s Affiliates and such Party’s stockholders that may be required or reasonably requested in connection with any action contemplated by this Section 5.1. If Nautilus, Merger Sub or the Company become aware of any event or information that, pursuant to the Securities Act or the Exchange Act, should be disclosed in an amendment or supplement to the Registration Statement or Proxy Statement, as the case may be, then such Party, as the case may be, shall promptly inform the other Parties thereof and shall cooperate with such other Parties in filing such amendment or supplement with the SEC and, if appropriate, in mailing such amendment or supplement to the Nautilus stockholders.

(b) Prior to the Effective Time, Nautilus shall use commercially reasonable efforts to obtain all regulatory approvals needed to ensure that the Nautilus Common Stock to be issued in the Merger (to the extent required) shall be registered or qualified or exempt from registration or qualification under the securities law of every jurisdiction of the United States in which any registered holder of Company Capital Stock has an address of record on the applicable record date for determining the holders of Company Capital Stock entitled to notice of and to vote pursuant to the Company Stockholder Written Consent; provided, however, that Nautilus shall not be required: (i) to qualify to do business as a foreign corporation in any jurisdiction in which it is not now qualified; or (ii) to file a general consent to service of process in any jurisdiction.

(c) The Company shall reasonably cooperate with Nautilus and provide, and require its Representatives to provide, Nautilus and its Representatives, with all true, correct and complete information regarding the Company or its Subsidiaries that is required by law to be included in the Registration Statement or reasonably requested by Nautilus to be included in the Registration Statement. Without limiting the foregoing, the Company will use commercially reasonable efforts to cause to be delivered to Nautilus a letter of the Company’s independent accounting firm, dated no more than two Business Days before the date on which the Registration Statement becomes effective (and reasonably satisfactory in form and substance to Nautilus), that is customary in scope and substance for letters delivered by independent public accountants in connection with registration statements similar to the Registration Statement.

5.2 Company Stockholder Written Consent.

(a) Promptly after the Registration Statement shall have been declared effective under the Securities Act, and in any event no later than five Business Days thereafter, the Company shall obtain the approval by written consent from Company stockholders sufficient for the Required Company Stockholder Vote in lieu of a meeting pursuant to Section 228 of the DGCL, for purposes of (i) adopting and approving this Agreement and the Contemplated Transactions, (ii) acknowledging that the approval given thereby is irrevocable and that such stockholder is aware of its rights to demand appraisal for its shares pursuant to Section 262 of the DGCL, a copy of which will be attached thereto, and that such stockholder has received and read a copy of Section 262 of the DGCL, and (iii) acknowledging that by its approval of the Merger it is not entitled to appraisal rights with respect to its shares in connection with the Merger and thereby waives any rights to receive payment of the fair value of its capital stock under the DGCL. Under no circumstances shall the Company assert that any other approval or consent is necessary by its stockholders to approve this Agreement and the Contemplated Transactions.

(b) Reasonably promptly following receipt of the Required Company Stockholder Vote, the Company shall prepare and mail a notice (the “Stockholder Notice”) to every stockholder of the Company that did not execute the Company Stockholder Written Consent. The Stockholder Notice shall (i) be a statement to the effect that the Company Board determined that the Merger is advisable in accordance with Section 251(b) of the DGCL and in the best interests of the stockholders of the Company and approved and adopted this Agreement, the Merger and the other Contemplated Transactions, (ii) provide the stockholders of the Company to whom it is sent with notice of the actions taken in the Company Stockholder Written Consent, including the adoption and approval of this Agreement, the Merger and the other Contemplated Transactions in accordance with Section 228(e) of the DGCL and the certificate of incorporation and bylaws of the Company and (iii) include a description of the appraisal rights of the Company’s stockholders available under the DGCL, along with such other information as is required thereunder and pursuant to applicable Law. All materials (including any amendments thereto) submitted to the stockholders of the Company in accordance with this Section 5.2(b) shall be subject to Nautilus’ advance review and reasonable approval.

(c) The Company agrees that, subject to Section 5.2(d): (i) the Company Board shall recommend that the Company’s stockholders vote to adopt and approve this Agreement and the Contemplated Transactions and shall use commercially reasonable efforts to solicit such approval within the time set forth in Section 5.2(a) (the recommendation of the

Company Board that the Company’s stockholders vote to adopt and approve this Agreement being referred to as the “Company Board Recommendation”); and (ii) the Company Board Recommendation shall not be withdrawn or modified (and the Company Board shall not publicly propose to withdraw or modify the Company Board Recommendation) in a manner adverse to Nautilus, and no resolution by the Company Board or any committee thereof to withdraw or modify the Company Board Recommendation in a manner adverse to Nautilus or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed.

(d) Notwithstanding anything to the contrary contained in Section 5.2(c), and subject to compliance with Section 4.4 and Section 5.2, if at any time prior to approval and adoption of this Agreement by the Required Company Stockholder Vote, the Company receives a bona fide written Superior Offer, the Company Board may withhold, amend, withdraw or modify the Company Board Recommendation (or publicly propose to withhold, amend, withdraw or modify the Company Board Recommendation) in a manner adverse to Nautilus (collectively, a “Company Board Adverse Recommendation Change”) if, but only if, following the receipt of and on account of such Superior Offer, (i) the Company Board determines in good faith, based on the advice of its outside legal counsel, that the failure to withhold, amend, withdraw or modify such recommendation would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, (ii) the Company has, and has caused its financial advisors and outside legal counsel to, during the Company Notice Period (as defined below), negotiate with Nautilus in good faith to make such adjustments to the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Offer, and (iii) if after Nautilus shall have delivered to the Company a written offer to alter the terms or conditions of this Agreement during the Company Notice Period, the Company Board shall have determined in good faith, based on the advice of its outside legal counsel, that the failure to withhold, amend, withdraw or modify the Company Board Recommendation would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law (after taking into account such alterations of the terms and conditions of this Agreement); provided that Nautilus receives written notice from the Company confirming that the Company Board has determined to change its recommendation at least four Business Days in advance of the Company Board Adverse Recommendation Change (the “Company Notice Period”), which notice shall include a description in reasonable detail of the reasons for such Company Board Adverse Recommendation Change, and written copies of any relevant proposed transaction agreements with any party making a potential Superior Offer. In the event of any material amendment to any Superior Offer (including any revision in the amount, form or mix of consideration the Company’s stockholders would receive as a result of such potential Superior Offer), the Company shall be required to provide Nautilus with notice of such material amendment and the Company Notice Period shall be extended, if applicable, to ensure that at least three Business Days remain in the Company Notice Period following such notification during which the parties shall comply again with the requirements of this Section 5.2(d) and the Company Board shall not make a Company Board Adverse Recommendation Change prior to the end of such Company Notice Period as so extended.

(e) Other than in connection with a bona fide written Superior Offer (which shall be subject to Section 5.2(d)), the Company Board may make a Company Board Adverse Recommendation Change in response to a Company Change in Circumstance, if and only if:

(A) the Company Board determines in good faith, after consultation with the Company’s outside legal counsel, that the failure to do so would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law; (B) Nautilus receives written notice from the Company confirming that the Company Board has determined to change its recommendation at least four Business Days in advance of the Company Board Adverse Recommendation Change (the “Company Change in Circumstance Notice”); and (C) (1) the Company shall have specified the Company Change in Circumstance in reasonable detail, (2) the Company shall have given Nautilus four business days after the Company Change in Circumstance Notice to propose revisions to the terms of this Agreement or make another proposal so that such Company Change in Circumstance would no longer necessitate a Company Board Adverse Recommendation Change, and shall have negotiated in good faith with Nautilus with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of such negotiations and giving effect to the proposals made by Nautilus, if any, after consultation with outside legal counsel, the Company Board shall have determined, in good faith, that the failure to make the Company Board Adverse Recommendation Change in response to such Company Change in Circumstance would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law. For the avoidance of doubt, the provisions of this Section 5.2(e) shall also apply to any material change to the facts and circumstances relating to such Company Change in Circumstance and require a new Company Change in Circumstance Notice, except that the references to four business days shall be deemed to be three business days.

(f) The Company’s obligation to solicit the consent of its stockholders to sign the Company Stockholder Written Consent in accordance with Section 5.2(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or other Acquisition Proposal, or by any Company Board Adverse Recommendation Change.

5.3 Nautilus Stockholders’ Meeting.

(a) Nautilus shall take all action necessary under applicable Law to call, give notice of and hold a meeting of the holders of Nautilus Common Stock to consider and vote to approve this Agreement and the Contemplated Transactions, including the issuance of the shares of Nautilus Common Stock to the stockholders of the Company pursuant to the terms of this Agreement and the Nautilus Charter Amendment (collectively, the “Nautilus Stockholder Matters” and such meeting, the “Nautilus Stockholders’ Meeting”). The Nautilus Stockholders’ Meeting shall be held as promptly as practicable after the Registration Statement is declared effective under the Securities Act. Nautilus shall take reasonable measures to ensure that all proxies solicited in connection with the Nautilus Stockholders’ Meeting are solicited in compliance with all applicable Law. Notwithstanding anything to the contrary contained herein, if on the date of the Nautilus Stockholders’ Meeting, or a date preceding the date on which the Nautilus Stockholders’ Meeting is scheduled, Nautilus reasonably believes that (i) it will not receive proxies sufficient to obtain the Required Nautilus Stockholder Vote, whether or not a quorum would be present or (ii) it will not have sufficient shares of Nautilus Common Stock represented (whether in person or by proxy) to constitute a quorum necessary to conduct the business of the Nautilus Stockholders’ Meeting, Nautilus may postpone or adjourn, or make one or more successive postponements or adjournments of, the Nautilus Stockholders’ Meeting as

long as the date of the Nautilus Stockholders’ Meeting is not postponed or adjourned more than an aggregate of 30 calendar days in connection with any postponements or adjournments.

(b) Nautilus agrees that, subject to Section 5.3(c): (i) the Nautilus Board shall recommend that the holders of Nautilus Common Stock vote to approve the Nautilus Stockholder Matters and shall use commercially reasonable efforts to solicit such approval within the timeframe set forth in Section 5.3(a) above, (ii) the Proxy Statement shall include a statement to the effect that the Nautilus Board recommends that Nautilus’ stockholders vote to approve the Nautilus Stockholder Matters (the recommendation of the Nautilus Board being referred to as the “Nautilus Board Recommendation”); and (iii) the Nautilus Board Recommendation shall not be withheld, amended, withdrawn or modified (and the Nautilus Board shall not publicly propose to withhold, amend, withdraw or modify the Nautilus Board Recommendation) in a manner adverse to the Company, and no resolution by the Nautilus Board or any committee thereof to withdraw or modify the Nautilus Board Recommendation in a manner adverse to the Company or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed (the actions set forth in the foregoing clause (iii), collectively, a “Nautilus Board Adverse Recommendation Change”).

(c) Notwithstanding anything to the contrary contained in Section 5.3(b), and subject to compliance with Section 4.4 and Section 5.3, if at any time prior to the approval of Nautilus Stockholder Matters by the Required Nautilus Stockholder Vote, Nautilus receives a bona fide written Superior Offer, the Nautilus Board may make a Nautilus Board Adverse Recommendation Change if, but only if, following the receipt of and on account of such Superior Offer, (i) the Nautilus Board determines in good faith, based on the advice of its outside legal counsel, that the failure to make a Nautilus Board Adverse Recommendation Change would reasonably likely to be inconsistent with its fiduciary duties under applicable Law, (ii) Nautilus has, and has caused its financial advisors and outside legal counsel to, during the Nautilus Notice Period (as defined below), negotiate with the Company in good faith to make such adjustments to the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Offer, and (iii) if after the Company shall have delivered to Nautilus a written offer to alter the terms or conditions of this Agreement during the Nautilus Notice Period, the Nautilus Board shall have determined in good faith, based on the advice of its outside legal counsel, that the failure to withhold, amend, withdraw or modify the Nautilus Board Recommendation would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law (after taking into account such alterations of the terms and conditions of this Agreement); provided that the Company receives written notice from Nautilus confirming that the Nautilus Board has determined to change its recommendation at least four Business Days in advance of such Nautilus Board Adverse Recommendation Change, (the “Nautilus Notice Period”), which notice shall include a description in reasonable detail of the reasons for such Nautilus Board Adverse Recommendation Change and, if such reasons are related to a Superior Offer, written copies of any relevant proposed transaction agreements with any party making a potential Superior Offer. In the event of any material amendment to any Superior Offer, Nautilus shall be required to provide the Company with notice of such material amendment and the Nautilus Notice Period shall be extended, if applicable, to ensure that at least three Business Days remain in the Nautilus Notice Period following such notification during which the parties shall comply again with the requirements of this Section 5.3(c) and the Nautilus Board shall not

make a Nautilus Board Adverse Recommendation Change prior to the end of such Nautilus Notice Period as so extended.

(d) Other than in connection with a bona fide written Superior Officer (which shall be subject to Section 5.3(c)), the Nautilus Board may make a Nautilus Board Adverse Recommendation Change in response to a Nautilus Change in Circumstance, if and only if: (A) the Nautilus Board determines in good faith, after consultation with the Company’s outside legal counsel, that the failure to do so is reasonably likely to be inconsistent with its fiduciary duties under applicable Law; (B) the Company receives written notice from Nautilus confirming that the Nautilus Board has determined to change its recommendation at least four Business Days in advance of the Nautilus Board Adverse Recommendation Change (the “Nautilus Change in Circumstance Notice”); and (C) (1) Nautilus shall have specified the Nautilus Change in Circumstance in reasonable detail, (2) Nautilus shall have given the Company four business days after the Nautilus Change in Circumstance Notice to propose revisions to the terms of this Agreement or make another proposal so that such Nautilus Change in Circumstance would no longer necessitate a Nautilus Board Adverse Recommendation Change, and shall have negotiated in good faith with the Company with respect to such proposed revisions or other proposal, if any, and (3) after considering the results of such negotiations and giving effect to the proposals made by the Company, if any, after consultation with outside legal counsel, the Nautilus Board shall have determined, in good faith, that the failure to make the Nautilus Board Adverse Recommendation Change in response to such Nautilus Change in Circumstance is reasonably likely to be inconsistent with its fiduciary duties under applicable Law. For the avoidance of doubt, the provisions of this Section 5.3(d) shall also apply to any material change to the facts and circumstances relating to such Nautilus Change in Circumstance and require a new Nautilus Change in Circumstance Notice, except that the references to four business days shall be deemed to be three business days.

(e) Nautilus’ obligation to call, give notice of and hold the Nautilus Stockholders’ Meeting in accordance with Section 5.3(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or Acquisition Proposal, or by any withdrawal or modification of the Nautilus Board Recommendation.

(f) Nothing contained in this Agreement shall prohibit Nautilus or the Nautilus Board from complying with Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided however, that any disclosure made by Nautilus or the Nautilus Board pursuant to Rules 14d-9 and 14e-2(a) shall be limited to a statement that Nautilus is unable to take a position with respect to the bidder’s tender offer unless the Nautilus Board determines in good faith, after consultation with its outside legal counsel, that such statement would result in a breach of its fiduciary duties under applicable Law provided further, that any such disclosures (other than a “stop, look and listen” communication or similar communication of the type contemplated by Section 14d 9(f) under the Exchange Act) shall be deemed to be a change of the Nautilus Board Recommendation unless the Nautilus Board expressly publicly reaffirms the Nautilus Board Recommendation (i) in such communication or (ii) within three (3) Business Days after being requested in writing to do so by the Company.

5.4 Regulatory Approvals. Each Party shall use commercially reasonable efforts to file or otherwise submit, as soon as practicable after the date of this Agreement, all applications, notices, reports and other documents reasonably required to be filed by such Party with or otherwise submitted by such Party to any Governmental Body with respect to the Contemplated Transactions, and to submit promptly any additional information requested by any such Governmental Body.

5.5 Company Options and Company Warrants.

(a) Subject to Section 5.5(c), at the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time under the Company Plan, whether or not vested, shall be converted into and become an option to purchase Nautilus Common Stock, and Nautilus shall assume the Company Plans and each such Company Option in accordance with the terms (as in effect as of the date of this Agreement) of the Company Plans and the terms of the stock option agreement by which such Company Option is evidenced. All rights with respect to Company Common Stock under Company Options assumed by Nautilus shall thereupon be converted into rights with respect to Nautilus Common Stock. Accordingly, from and after the Effective Time: (i) each Company Option assumed by Nautilus may be exercised solely for shares of Nautilus Common Stock; (ii) the number of shares of Nautilus Common Stock subject to each Company Option assumed by Nautilus shall be determined by multiplying (A) the number of shares of Company Common Stock that were subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Nautilus Common Stock; (iii) the per share exercise price for the Nautilus Common Stock issuable upon exercise of each Company Option assumed by Nautilus shall be determined by dividing (A) the per share exercise price of Company Common Stock subject to such Company Option, as in effect immediately prior to the Effective Time, by (B) the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on the exercise of any Company Option assumed by Nautilus shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged; provided, however, that: (A) to the extent provided under the terms of a Company Option, such Company Option assumed by Nautilus in accordance with this Section 5.5(a) shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction with respect to Nautilus Common Stock subsequent to the Effective Time; and (B) the Nautilus Board or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to each Company Option assumed by Nautilus. Notwithstanding anything to the contrary in this Section 5.5(a), the conversion of each Company Option (regardless of whether such option qualifies as an “incentive stock option” within the meaning of Section 422 of the Code) into an option to purchase shares of Nautilus Common Stock shall be made in a manner consistent with Treasury Regulation Section 1.424-1, such that the conversion of a Company Option shall not constitute a “modification” of such Company Option for purposes of Section 409A or Section 424 of the Code.

(b) Nautilus shall file with the SEC, promptly (and no later than 30 days) after the Effective Time, a registration statement on Form S-8, if available for use by Nautilus,

relating to the shares of Nautilus Common Stock issuable with respect to Company Options assumed by Nautilus in accordance with Section 5.5(a).

(c) Subject to Section 5.5(c), at the Effective Time, each Company Warrant that is outstanding and unexercised immediately prior to the Effective Time, shall become converted into and become a warrant to purchase Nautilus Common Stock and Nautilus shall assume each such Company Warrant in accordance with its terms. All rights with respect to Company Common Stock or Company Preferred Stock under Company Warrants assumed by Nautilus shall thereupon be converted into rights with respect to Nautilus Common Stock. Accordingly, from and after the Effective Time: (i) each Company Warrant assumed by Nautilus may be exercised solely for shares of Nautilus Common Stock; (ii) the number of shares of Nautilus Common Stock subject to each Company Warrant assumed by Nautilus shall be determined by multiplying (A) the number of shares of Company Common Stock, or the number of shares of Company Common Stock issuable upon conversion of the shares of Company Preferred Stock issuable upon exercise of the Company Warrant, as applicable, that were subject to such Company Warrant immediately prior to the Effective Time by (B) the Exchange Ratio and rounding the resulting number down to the nearest whole number of shares of Nautilus Common Stock; (iii) the per share exercise price for the Nautilus Common Stock issuable upon exercise of each Company Warrant assumed by Nautilus shall be determined by dividing the per share exercise price of Company Common Stock or Company Preferred Stock, subject to such Company Warrant, as in effect immediately prior to the Effective Time, by the Exchange Ratio and rounding the resulting exercise price up to the nearest whole cent; and (iv) any restriction on any Company Warrant assumed by Nautilus shall continue in full force and effect and the terms and other provisions of such Company Warrant shall otherwise remain unchanged.

(d) Prior to the Effective Time, the Company shall take all actions that may be necessary (under the Company Plans and otherwise) to effectuate the provisions of this Section 5.5 and to ensure that, from and after the Effective Time, holders of Company Options have no rights with respect thereto other than those specifically provided in this Section 5.5.

5.6 Nautilus Options. Prior to the Closing, the Nautilus Board shall have adopted appropriate resolutions and taken all other actions necessary and appropriate to provide that each unexpired and unexercised Nautilus Option, whether vested or unvested, shall be accelerated in full effective as of immediately prior to the Effective Time.

5.7 Employee Benefits. Nautilus and the Company shall cause Nautilus to comply with the terms of any employment, severance, retention, change of control, or similar agreement specified on Section 3.17(a) of the Nautilus Disclosure Schedule, subject to the provisions of such agreements.

5.8 Indemnification of Officers and Directors.

(a) From the Effective Time through the sixth anniversary of the date on which the Effective Time occurs, each of Nautilus and the Surviving Corporation shall indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director or officer of Nautilus or the Company, respectively (the “D&O Indemnified Parties”), against all claims, losses, liabilities,

damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements (collectively, “Costs”), incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the D&O Indemnified Party is or was a director or officer of Nautilus or of the Company, whether asserted or claimed prior to, at or after the Effective Time, in each case, to the fullest extent permitted under the DGCL for directors or officers of Delaware corporations. Each D&O Indemnified Party will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Nautilus and the Surviving Corporation, jointly and severally, upon receipt by Nautilus or the Surviving Corporation from the D&O Indemnified Party of a request therefor; provided that any such person to whom expenses are advanced provides an undertaking to Nautilus, to the extent then required by the DGCL, to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

(b) The provisions of the certificate of incorporation and bylaws of Nautilus with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of Nautilus that are presently set forth in the certificate of incorporation and bylaws of Nautilus shall not be amended, modified or repealed for a period of six years from the Effective Time in a manner that would adversely affect the rights thereunder of individuals who, at or prior to the Effective Time, were officers or directors of Nautilus. The certificate of incorporation and bylaws of the Surviving Corporation shall contain, and Nautilus shall cause the certificate of incorporation and bylaws of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers as those presently set forth in the certificate of incorporation and bylaws of Nautilus.

(c) From and after the Effective Time, (i) the Surviving Corporation shall fulfill and honor in all respects the obligations of the Company to its D&O Indemnified Parties as of immediately prior to the Closing pursuant to any indemnification provisions under the Company’s Organizational Documents and pursuant to any indemnification agreements between the Company and such D&O Indemnified Parties, with respect to claims arising out of matters occurring at or prior to the Effective Time and (ii) Nautilus shall fulfill and honor in all respects the obligations of Nautilus to its D&O Indemnified Parties as of immediately prior to the Closing pursuant to any indemnification provisions under Nautilus’ Organizational Documents and pursuant to any indemnification agreements between Nautilus and such D&O Indemnified Parties, with respect to claims arising out of matters occurring at or prior to the Effective Time.

(d) From and after the Effective Time, Nautilus shall maintain directors’ and officers’ liability insurance policies, with an effective date as of the Closing Date, on commercially available terms and conditions and with coverage limits customary for U.S. public companies similarly situated to Nautilus. In addition, Nautilus shall purchase, prior to the Effective Time, a six-year prepaid “tail policy” (the cost of which shall be a Nautilus Transaction Expense) for the non-cancellable extension of the directors’ and officers’ liability coverage of Nautilus’ existing directors’ and officers’ insurance policies for a claims reporting or discovery period of at least six years from and after the Effective Time with respect to any claim related to any period of time at or prior to the Effective Time with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under Nautilus’ existing policies

as of the date of this Agreement with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a director or officer of Nautilus by reason of him or her serving in such capacity that existed or occurred at or prior to the Effective Time (including in connection with this Agreement or the Contemplated Transactions or in connection with Nautilus’ initial public offering of shares of Nautilus Common Stock).

(e) From and after the Effective Time, Nautilus shall pay all expenses, including reasonable attorneys’ fees, that are incurred by the persons referred to in this Section 5.8 in connection with their successful enforcement of the rights provided to such persons in this Section 5.8.

(f) The provisions of this Section 5.8 are intended to be in addition to the rights otherwise available to the current and former officers and directors of Nautilus and the Company by law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the D&O Indemnified Parties, their heirs and their representatives.

(g) In the event Nautilus or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Nautilus or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 5.8. Nautilus shall cause the Surviving Corporation to perform all of the obligations of the Surviving Corporation under this Section 5.8.

5.9 Additional Agreements. The Parties shall use commercially reasonable efforts to cause to be taken all actions necessary to consummate the Contemplated Transactions. Without limiting the generality of the foregoing, each Party to this Agreement: (a) shall make all filings and other submissions (if any) and give all notices (if any) required to be made and given by such Party in connection with the Contemplated Transactions; (b) shall use commercially reasonable efforts to obtain each Consent (if any) reasonably required to be obtained (pursuant to any applicable Law or Contract, or otherwise) by such Party in connection with the Contemplated Transactions or for such Contract to remain in full force and effect; (c) shall use commercially reasonable efforts to lift any injunction prohibiting, or any other legal bar to, the Contemplated Transactions; and (d) shall use commercially reasonable efforts to satisfy the conditions precedent to the consummation of this Agreement.

5.10 Disclosure. Without limiting any Party’s obligations under the Confidentiality Agreement, no Party shall, and no Party shall permit any of its Subsidiaries or any Representative of such Party to, issue any press release or make any disclosure (to any customers or employees of such Party, to the public or otherwise) regarding the Contemplated Transactions unless: (a) the other Party shall have approved such press release or disclosure in writing, such approval not to be unreasonably conditioned, withheld or delayed; or (b) such Party shall have determined in good faith, upon the advice of outside legal counsel, that such disclosure is required by applicable Law and, to the extent practicable, before such press release or disclosure

is issued or made, such Party advises the other Party of, and consults with the other Party regarding, the text of such press release or disclosure; provided, however, that each of the Company and Nautilus may make any public statement in response to specific questions by the press, analysts, investors or those attending industry conferences or financial analyst conference calls, so long as any such statements are consistent with previous press releases, public disclosures or public statements made by the Company or Nautilus in compliance with this Section 5.10.

5.11 Listing. Nautilus shall use its commercially reasonable efforts: (a) to maintain its existing listing on NASDAQ until the Closing Date and to obtain approval of the listing of the combined company on NASDAQ; (b) without derogating from the generality of the requirements of clause “(a)” and to the extent required by the rules and regulations of NASDAQ, to (i) prepare and submit to NASDAQ a notification form for the listing of the shares of Nautilus Common Stock to be issued in connection with the Contemplated Transactions and (ii) to cause such shares to be approved for listing (subject to official notice of issuance); and (c) to the extent required by Nasdaq Marketplace Rule 5110, to file an initial listing application for the Nautilus Common Stock on NASDAQ (the “NASDAQ Listing Application”) and to cause such NASDAQ Listing Application to be conditionally approved prior to the Effective Time. Each Party will promptly inform the other Party of all verbal or written communications between NASDAQ and such Party or its representatives. The Parties will use commercially reasonable efforts to coordinate with respect to compliance with NASDAQ rules and regulations. The Company agrees to pay all NASDAQ fees associated with the NASDAQ Listing Application. The Company will cooperate with Nautilus as reasonably requested by Nautilus with respect to the NASDAQ Listing Application and promptly furnish to Nautilus all information concerning the Company and its stockholders that may be required or reasonably requested in connection with any action contemplated by this Section 5.11.

5.12 Tax Matters.

(a) The Parties shall not file any U.S. federal, state or local Tax Return in a manner that is inconsistent with the treatment of the Merger as a reorganization within the meaning of Section 368(a) of the Code for U.S. federal, state and other relevant Tax purposes, unless otherwise required by applicable Law.

(b) The Parties shall use their respective reasonable best efforts to cause the Merger to qualify, and will not take any action or cause any action to be taken which action would reasonably be expected to prevent the Merger from qualifying, as a reorganization within the meaning of Section 368(a) of the Code.

(c) Each of the Parties agrees to prepare and file all U.S. federal income Tax Returns in accordance with the foregoing provisions of this Section 5.12 and shall not take any position inconsistent therewith in the course of any audit, litigation or other Legal Proceeding with respect to U.S. federal income taxes, except as otherwise required by applicable Law or following a final determination by a court of competent jurisdiction or other final administrative decision by an applicable Governmental Body.

(d) The Company shall use its reasonable best efforts to obtain the opinion of Sidley Austin LLP or another firm of national reputation (“Tax Counsel”) to the effect that the Merger will be treated, for U.S. federal income tax purposes, as a reorganization within the meaning of Section 368(a) of the Code (the “Tax Opinion”), dated as of the Closing and also dated as of any earlier date as may be required by the SEC in connection with the effectiveness of the Registration Statement. As a condition precedent to the rendering of the Tax Opinion, Nautilus, Merger Sub and the Company shall use reasonable best efforts to execute and deliver to Tax Counsel tax representation letters (the “Tax Representation Letters”), with such customary representations as Tax Counsel shall reasonably request (taking into account the ownership and control of Nautilus following consummation of the Merger), dated and executed as of the date (or dates) of such Tax Opinion, on which such Tax Representation Letters Tax Counsel shall be entitled to rely in delivering the Tax Opinion.

5.13 Legends. Nautilus shall be entitled to place appropriate legends on the book entries and/or certificates evidencing any shares of Nautilus Common Stock to be received in the Merger by equityholders of the Company who may be considered “affiliates” of Nautilus for purposes of Rules 144 and 145 under the Securities Act reflecting the restrictions set forth in Rules 144 and 145 and to issue appropriate stop transfer instructions to the transfer agent for Nautilus Common Stock.

5.14 Directors and Officers.
