(c) The directors and officers of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are directors and officers of Merger Sub immediately prior to the Effective Time.

1.5 Conversion of Shares.

(a) Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of the Company:

(i) any shares of Company Common Stock held by any wholly-owned Subsidiary of the Company immediately prior to the Effective Time (or held in the Company’s treasury) shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) any shares of Company Common Stock held by Parent, Merger Sub or any other wholly-owned Subsidiary of Parent 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;

(iii) except as provided in clauses “(i)” and “(ii)” above and subject to Sections 1.5(c) and 1.5(d), each share of Company Common Stock outstanding immediately prior to the Effective Time shall be converted into the right to receive 0.7802 of a share of Parent Common Stock (such number as may be adjusted in accordance with Section 1.5(b), the “Exchange Ratio”); and

(iv) each share of the Common Stock, $0.001 par value per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Surviving Corporation.

(b) If, during the period from the date of this Agreement through the Effective Time, the outstanding shares of Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, or if a stock dividend is declared by the Company or Parent during such period, then the Exchange Ratio shall be adjusted to the extent appropriate to provide the same economic effect as contemplated by this Agreement prior to such action.

(c) If any shares of Company Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other Contract with the Company or under which the Company has any rights, then (except to the extent provided in any binding agreement between the Company and the holder thereof): (i) the shares of Parent Common Stock issued in exchange for such shares of Company Common Stock will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition; and (ii) the certificates representing such shares of Parent Common Stock may accordingly be marked with appropriate legends. Prior to the Effective Time, the Company shall use commercially reasonable efforts to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase agreement or other Contract.

(d) No fractional shares of Parent 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 Common Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender of such holder’s Company Stock Certificate(s) (as defined in Section 1.6), or non-certificated shares of Company Common Stock represented by book entry (“Book Entry Shares”) be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the closing price of a share of Parent Common Stock on the NASDAQ Global Market on the Closing Date.

1.6 Closing of the Company’s Transfer Books. At the Effective Time: (a) all shares of Company Common Stock outstanding immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and all holders of Book Entry Shares or of certificates representing shares of Company Common Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company, except the right to receive shares of Parent Common Stock as contemplated by Section 1.5, cash in lieu of any fractional share of Parent Common Stock pursuant to Section 1.5(d) and any dividends or other distributions pursuant to Section 1.7(c); and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Common 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 Common Stock outstanding immediately prior to the Effective Time (a “Company Stock Certificate”) or a Book Entry Share is presented to the Exchange Agent (as defined in Section 1.7) or to the Surviving Corporation or Parent, such Company Stock Certificate or Book Entry Share shall be canceled and shall be exchanged as provided in Section 1.7.

1.7 Exchange of Certificates.

(a) On or prior to the Closing Date, Parent shall select a reputable bank or trust company reasonably satisfactory to the Company to act as exchange agent in the Merger (the “Exchange Agent”). Promptly after the Effective Time, Parent shall cause to be deposited with the Exchange Agent: (i) certificates representing the shares of Parent Common Stock issuable pursuant to Section 1.5; and (ii) cash sufficient to make payments in lieu of fractional shares in accordance with Section 1.5(d). The shares of Parent 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 of Parent Common Stock, are referred to collectively as the “Exchange Fund.”

(b) Promptly after the Effective Time, the Exchange Agent will mail to the Persons who were record holders of Company Stock Certificates or Book Entry Shares immediately prior to the Effective Time: (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify and the Company shall reasonably approve prior to the Effective Time (including a provision confirming that delivery of Company Stock Certificates or Book Entry Shares shall be effected, and risk of loss and title to Company Stock Certificates or Book Entry Shares shall pass, only upon delivery of such Company Stock Certificates or Book Entry Shares to the Exchange Agent); and (ii) instructions for use in effecting the surrender of Company Stock Certificates or Book Entry Shares in exchange for certificates representing Parent Common Stock. Upon surrender of a Company Stock Certificate or Book Entry Shares 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 Parent: (A) the holder of such Company Stock Certificate or Book Entry Shares shall be entitled to receive in exchange therefor a certificate representing the number of whole shares of Parent Common Stock that such holder has the right to receive pursuant to the provisions of Section 1.5 (and cash in lieu of any fractional share of Parent Common Stock pursuant to Section 1.5(d) and any dividends or other distributions pursuant to Section 1.7(c)); and (B) the Company Stock Certificate or Book Entry Shares so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.7(b), each Company Stock Certificate and Book Entry Share shall be deemed, from and after the Effective Time, to represent only the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock) as contemplated by Section 1.5. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its reasonable discretion and as a condition to the issuance of any certificate representing Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and indemnification obligation against any claim that may be made against the Exchange Agent, Parent or the Surviving Corporation with respect to such Company Stock Certificate.

(c) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Effective Time shall be paid or otherwise delivered to the holder of any unsurrendered Company Stock Certificate or Book Entry Share with respect to the shares of Parent Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate or Book Entry Share 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 and Book Entry Shares as of the date that is one year after the date on which the Merger becomes effective shall be delivered to Parent upon demand, and any holders of Company Stock Certificates or Book Entry Shares who have not theretofore surrendered their Company Stock Certificates or Book Entry Shares in accordance with this Section 1.7 shall thereafter look only to Parent for satisfaction of their claims for Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to shares of Parent Common Stock.

(e) Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Common Stock such amounts as may be required to be deducted or withheld from such consideration under the Code or any provision of state, local or foreign tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld and timely paid to the appropriate Governmental Body, 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) Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Common Stock or to any other Person with respect to any shares of Parent 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 other Legal Requirement.

1.8 Tax Consequences. For U.S. federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of Section 368(a) of the Code. The parties to this Agreement adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

1.9 Further Action. If, at any time after the Effective Time, any further action is determined by Parent or 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 Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

39.

(c) Parent has delivered or Made Available to the Company an accurate and complete list, by country and as of the date hereof, of each Parent Employee Plan and each Parent Employee Agreement. None of the Accelrys Corporations intends, and none of the Accelrys Corporations has committed, to establish or enter into any new Parent Employee Plan or Parent Employee Agreement, or to modify any Parent Employee Plan or Parent Employee Agreement (except to conform any such Parent Employee Plan or Parent Employee Agreement to the requirements of any applicable Legal Requirements, in each case as previously disclosed to Parent in writing or as required by this Agreement).

(d) Parent has delivered or Made Available to the Company accurate and complete copies of: (i) all documents setting forth the terms of each Parent Employee Plan and each Parent Employee Agreement, including all amendments thereto and all related trust documents; (ii) the three most recent annual reports (Form Series 5500 and all schedules and financial statements attached thereto), if any, required under applicable Legal Requirements in connection with each Parent Employee Plan; (iii) if the Parent Employee Plan is subject to any minimum funding standards (including those of Section 302 of ERISA), the most recent annual and periodic accounting of Parent Employee Plan assets, if any; (iv) the most recent summary plan description together with the summaries of material modifications thereto, if any, required under ERISA or any similar Legal Requirement with respect to each Parent Employee Plan; (v) all material written Contracts relating to each Parent Employee Plan, including administrative service agreements and group insurance contracts; (vi) all discrimination tests required under the Code for each Parent Employee Plan intended to be qualified under Section 401(a) of the Code for the three most recent plan years; and (vii) the most recent IRS determination or opinion letter issued with respect to each Parent Employee Plan intended to be qualified under Section 401(a) of the Code.

(e) Each of the Accelrys Corporations and Parent Affiliates has performed in all material respects all obligations required to be performed by it under each Parent Employee Plan, and each Parent Employee Plan has been established and maintained in all material respects in accordance with its terms. Any Parent Employee Plan intended to be qualified under Section 401(a) of the Code has obtained a favorable determination letter (or opinion letter, if applicable) as to its qualified status under the Code. All Parent Employee Plans required to have been approved by any foreign Governmental Body have been so approved, no such approval has been revoked (or, to the knowledge of Parent, has revocation been threatened) and no event has occurred since the date of the most recent approval or application therefor relating to any such Parent Employee Plan that would reasonably be expected to materially affect any such approval relating thereto or materially increase the costs relating thereto. Each Parent Employee Plan intended to be tax qualified under applicable Legal Requirements is so tax qualified, and no event has occurred and no circumstance or condition exists that would reasonably be expected to result in the disqualification of any such Parent Employee Plan. No “prohibited transaction,” within the meaning of Section 4975 of the Code or Sections 406 and 407 of ERISA, and not otherwise exempt under Section 408 of ERISA, has occurred with respect to any Parent Employee Plan. Each Parent Employee Plan (other than any Parent Employee Plan to be terminated prior to the Effective Time in accordance with this Agreement) can be amended, terminated or otherwise discontinued after the Closing in accordance with its terms, without liability to Parent, any of the Accelrys Corporations or any Parent Affiliate (other than any liability for ordinary administration expenses). There are no audits or inquiries pending or, to the knowledge of Parent, threatened by the IRS, the DOL or any other Governmental Body with respect to any Parent Employee Plan. Except as set forth in Part 3.16 of the Parent Disclosure Schedule, there are no pending or, to the knowledge of Parent, threatened claims or Legal Proceedings involving any Parent Employee Plan other than routine claims for benefits. None of the Accelrys Corporations, and no Parent Affiliate, has ever incurred any material penalty or Tax with respect to any Parent Employee Plan under applicable Legal Requirements. Each of the Accelrys Corporations and Parent Affiliates has made all contributions and other payments required by and due under the terms of each Parent Employee Plan. Neither the terms nor the performance of any Parent Employee Agreement or Parent Employee Plan would reasonably be expected to result in gross income inclusion prior to, on or after the Effective Time pursuant to Section 409A(a)(1)(A) of the Code.

40.

(f) None of the Accelrys Corporations, and no Parent Affiliate, has ever maintained, established, sponsored, participated in or contributed to any: (i) Parent Pension Plan subject to Title IV of ERISA; (ii) “multiemployer plan” within the meaning of Section (3)(37) of ERISA; or (iii) plan described in Section 413 of the Code. No Parent Employee Plan is or has been funded by, associated with or related to a “voluntary employees’ beneficiary association” within the meaning of Section 501(c)(9) of the Code. None of the Accelrys Corporations, and no Parent Affiliate, has ever maintained, established, sponsored, participated in or contributed to any Parent Pension Plan in which stock of any of the Accelrys Corporations or any Parent Affiliate is or was held as a plan asset. The fair market value of the assets of each funded Parent Foreign Plan, the liability of each insurer for any Parent Foreign Plan funded through insurance, or the book reserve established for any Parent Foreign Plan, together with any accrued contributions, is sufficient to procure or provide in full for the accrued benefit obligations, with respect to all current and former participants in such Parent Foreign Plan according to the reasonable actuarial assumptions and valuations most recently used to determine employer contributions to and obligations under such Foreign Plan, and no Contemplated Transaction will cause any such assets or insurance obligations to be less than such benefit obligations. There are no liabilities of the Accelrys Corporations with respect to any Parent Employee Plan that are not properly accrued and reflected in the financial statements of Parent in accordance with GAAP.

(g) No Parent Employee Plan that is an employee welfare benefit plan (whether or not ERISA applies to such Parent Employee Plan) is, in whole or in part, self-funded or self-insured. No Parent Employee Plan provides (except at no cost to the Accelrys Corporations or any Parent Affiliate), or reflects or represents any liability of any of the Accelrys Corporations or any Parent Affiliate to provide, post-termination or retiree life insurance, post-termination or retiree health benefits or other post-termination or retiree employee welfare benefits to any Person for any reason, except as may be required by COBRA or other applicable Legal Requirements. Other than commitments made that involve no future costs to any of the Accelrys Corporations or any Parent Affiliate, none of the Accelrys Corporations nor any Parent Affiliate has ever represented, promised or contracted (whether in oral or written form) to any Parent Associate (either individually or to Parent Associates as a group) or any other Person that such Parent Associate(s) or other Person would be provided with post-termination or retiree life insurance, post-termination or retiree health benefit or other post-termination or retiree employee welfare benefits, except to the extent required by applicable Legal Requirements.

(h) Except as set forth in Part 3.16(h) of the Parent Disclosure Schedule, and except as expressly required or provided by this Agreement, neither the execution of this Agreement nor the consummation of the Contemplated Transactions will or would reasonably be expected to (either alone or upon the occurrence of termination of employment) constitute an event under any Parent Employee Plan, Parent Employee Agreement, trust or loan that will or may result (either alone or in connection with any other circumstance or event) in any payment (whether of severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any Parent Associate.

(j) There is no agreement, plan, arrangement or other Contract covering any Parent Associate, and no payments have been made or will be made in connection with the Merger to any Parent Associate, that, considered individually or considered collectively with any other such Contracts or payments, will, or would reasonably be expected to, be characterized as a “parachute payment” within the meaning of Section 280G(b)(2) of the Code or give rise directly or indirectly to the payment of any amount that would not be deductible pursuant to Section 162(m) of the Code (or any comparable provision under state or foreign Tax laws).

(i) if: (A) the Company has not breached its obligations under Section 4.4(a) in connection with the Company Acquisition Proposal referred to in the following clause “(B);” (B) after the date of this Agreement, an unsolicited Company Acquisition Proposal is made to the Company and is not withdrawn; (C) the Company Board determines in its good faith judgment, after consulting with a financial advisor of nationally recognized reputation and outside legal counsel, that such Company Acquisition Proposal constitutes a Company Superior Offer; (D) the Company Board does not effect, or cause the Company to effect, a Company Change in Recommendation at any time within four business days after Parent receives written notice from the Company confirming that the Company Board has determined that such Company Acquisition Proposal is a Company Superior Offer; (E) during such four business day period, if requested by Parent, the Company engages in good faith negotiations with Parent to amend this Agreement in such a manner that the Company Acquisition Proposal that was determined to constitute a Company Superior Offer no longer constitutes a Company Superior Offer; (F) at the end of such four business day period, such Company Acquisition Proposal has not been withdrawn and continues to constitute a Company Superior Offer (taking into account any changes to the terms of this Agreement proposed by Parent as a result of the negotiations required by clause “(E)” or otherwise); and (G) the Company Board determines in good faith, after having consulted with its outside legal counsel, that, in light of such Company Superior Offer, a failure to make a Company Change in Recommendation would reasonably be expected to constitute a breach of the fiduciary duties of the Company Board to the Company’s stockholders under applicable law; or

(ii) if: (A) other than the development or circumstances contemplated by clause “(i)” of this Section 5.2(c), a material development or change in circumstances occurs or arises after the date of this Agreement that was neither known to any Symyx Corporation or any Representative of any Symyx Corporation nor reasonably foreseeable to any Symyx Corporation as of the date of this Agreement (such material development or change in circumstances being referred to as a “Company Intervening Event”); provided, however, that (1) in no event shall the receipt, existence of or terms of a Company Acquisition Proposal or a Company Superior Offer or any inquiry relating thereto or the consequences thereof constitute a Company Intervening Event and (2) in no event shall any event, occurrence, fact, condition, effect, change or development that has an adverse effect on the business, financial condition or results of operations of any Accelrys Corporation, constitute a Company Intervening Event, unless such event, occurrence, fact, condition, effect, change or development has had or would reasonably be expected to have a Parent Material Adverse Effect; (B) at least four business days prior to any meeting of the Company Board at which the Company Board will consider whether such Company Intervening Event requires the Company Board to effect, or cause the Company to effect, a Company Change in Recommendation, the Company provides Parent with a written notice specifying the date and time of such meeting and the reasons for holding such meeting; (C) during such four business day period, if requested by Parent, the Company engages in good faith negotiations with Parent to amend this Agreement in such a manner that obviates the need for the Company Board to effect, or cause the Company to effect, a Company Change in Recommendation as a result of such Company Intervening Event; and (D) the Company Board determines in good faith, after having consulted with its outside legal counsel, that, in light of such Company Intervening Event, a failure to make a Company Change in Recommendation would reasonably be expected to constitute a breach of the fiduciary duties of the Company Board to the Company’s stockholders under applicable law.

58.

(d) Notwithstanding any Company Change in Recommendation, unless earlier terminated in accordance with Section 8.1, this Agreement shall be submitted to the holders of Company’s Common Stock at the Company Stockholders’ Meeting for the purpose of voting on the adoption of this Agreement and nothing contained in this Agreement shall be deemed to relieve the Company of such obligation.

Parent, in consultation with the Company shall set a record date for persons entitled to notice of, and to vote at, the Parent Stockholders’ Meeting and shall not change such record date without the prior written consent of the Company. The Parent Stockholders’ Meeting shall be held on the same date this Agreement would be submitted to the Company’s stockholders for adoption at the Company Stockholders’ Meeting (or, to the extent that Parent and the Company agree, as promptly as practicable thereafter). Parent shall ensure that all proxies solicited in connection with the Parent Stockholders’ Meeting are solicited in compliance with all applicable Legal Requirements. Notwithstanding anything to the contrary contained in this Agreement, Parent may after consultation with the Company adjourn or postpone the Parent Stockholders’ Meeting only: (i) to the extent necessary to ensure that any supplement or amendment to the Joint Proxy Statement/Prospectus that is required by applicable law is timely provided to Parent’s stockholders; (ii) if as of the time for which the Parent Stockholders’ Meeting is originally scheduled there are insufficient shares of Parent Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business to be conducted at the Parent Stockholders’ Meeting; or (iii) if additional time is reasonably required to solicit proxies in favor of the approval of the Parent Proposals.

(b) Subject to Section 5.3(c): (i) the Joint Proxy Statement/Prospectus shall include a statement to the effect that the Parent Board recommends that Parent’s stockholders vote to approve the Parent Proposals (the recommendation of the Parent Board that Parent’s stockholders vote to approve the Parent Proposals being referred to as the “Parent Board Recommendation”); (ii) the Parent Board Recommendation shall not, directly or indirectly, be withdrawn or modified in a manner adverse to the Company; (iii) neither the Parent Board nor any committee thereof shall: (A) fail to reaffirm the Parent Board Recommendation, or fail to publicly state that the Merger and this Agreement are in the best interest of Parent’s stockholders, within ten business days after the Company requests in writing that such action be taken; (B) fail to publicly announce, within ten business days after a tender offer or exchange offer relating to the securities of Parent shall have been commenced, a statement disclosing that the Parent Board recommends rejection of such tender or exchange offer; (C) fail to issue, within ten business days after a Parent Acquisition Proposal is publicly announced, a press release announcing its opposition to such Parent Acquisition Proposal; or (D) recommend, adopt or approve a Parent Acquisition Proposal; or (iv) resolve to take any action described in clauses “(ii)” or “(iii)” of this sentence (each of the foregoing actions described in clauses “(ii),” “(iii)” and “(iv)” being referred to as a “Parent Change in Recommendation”).

59.

(c) Notwithstanding anything to the contrary contained in Section 5.3(b) or elsewhere in this Agreement, at any time prior to the approval of the Parent Proposals by the Required Parent Stockholder Vote, the Parent Board may effect, or cause Parent to effect, as the case may be, a Parent Change in Recommendation:

(i) if: (A) Parent has not breached its obligations under Section 4.4(b) in connection with the Parent Acquisition Proposal referred to in the following clause “(B);” (B) after the date of this Agreement, an unsolicited Parent Acquisition Proposal is made to Parent and is not withdrawn; (C) the Parent Board determines in its good faith judgment, after consulting with a financial advisor of nationally recognized reputation and outside legal counsel, that such Parent Acquisition Proposal constitutes a Parent Superior Offer; (D) the Parent Board does not effect, or cause Parent to effect, a Parent Change in Recommendation at any time within four business days after the Company receives written notice from Parent confirming that the Parent Board has determined that such Parent Acquisition Proposal is a Parent Superior Offer; (E) during such four business day period, if requested by the Company, Parent engages in good faith negotiations with the Company to amend this Agreement in such a manner that the Parent Acquisition Proposal that was determined to constitute a Parent Superior Offer no longer constitutes a Parent Superior Offer; (F) at the end of such four business day period, such Parent Acquisition Proposal has not been withdrawn and continues to constitute a Parent Superior Offer (taking into account any changes to the terms of this Agreement proposed by the Company as a result of the negotiations required by clause “(E)” or otherwise); and (G) the Parent Board determines in good faith, after having consulted with its outside legal counsel, that, in light of such Parent Superior Offer, a failure to make a Parent Change in Recommendation would reasonably be expected to constitute a breach of the fiduciary duties of the Parent Board to Parent’s stockholders under applicable law; or

(ii) if: (A) other than the development or circumstances contemplated by clause “(i)” of this Section 5.3(c), a material development or change in circumstances occurs or arises after the date of this Agreement that was neither known to any Accelrys Corporation or any Representative of any Accelrys Corporation nor reasonably foreseeable to any Accelrys Corporation as of the date of this Agreement (such material development or change in circumstances being referred to as a “ Parent Intervening Event”); provided, however, that (1) in no event shall the receipt, existence of or terms of a Parent Acquisition Proposal or a Parent Superior Offer or any inquiry relating thereto or the consequences thereof constitute a Parent Intervening Event and (2) in no event shall any event, occurrence, fact, condition, effect, change or development that has an adverse effect on the business, financial condition or results of operations of any Symyx Corporation, constitute a Parent Intervening Event, unless such event, occurrence, fact, condition, effect, change or development has had or would reasonably be expected to have a Company Material Adverse Effect; (B) at least four business days prior to any meeting of the Parent Board at which the Parent Board will consider whether such Parent Intervening Event requires the Parent Board to effect, or cause Parent to effect, a Parent Change in Recommendation, Parent provides the Company with a written notice specifying the date and time of such meeting and the reasons for holding such meeting; (C) during such four business day period, if requested by the Company, Parent engages in good faith negotiations with the Company to amend this Agreement in such a manner that obviates the need for the Parent Board to effect, or cause Parent to effect, a Parent Change in Recommendation as a result of such Parent Intervening Event; and (D) the Parent Board determines in good faith, after having consulted with its outside legal counsel, that, in light of such Parent Intervening Event, the failure to make a Parent Change in Recommendation would reasonably be expected to constitute a breach of the fiduciary duties of the Parent Board to Parent’s stockholders under applicable law.

60.

(d) Notwithstanding any Parent Change in Recommendation, unless earlier terminated in accordance with Section 8.1, this Agreement shall be submitted to the holders of Parent Common Stock at the Parent Stockholders’ Meeting for the purpose of voting on the Parent Proposals and nothing contained in this Agreement shall be deemed to relieve Parent of such obligation.

5.4 Stock Options and Company ESPP.

(a) At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time, whether or not vested, shall be converted into and become an option to purchase Parent Common Stock, and Parent shall assume such Company Option in accordance with the terms (as in effect as of the date of this Agreement) of the applicable Company Option Plan and the terms of the Contract by which such Company Option is evidenced. All rights with respect to Company Common Stock under Company Options assumed by Parent shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time: (A) each Company Option assumed by Parent may be exercised solely for shares of Parent Common Stock; (B) the number of shares of Parent Common Stock subject to each Company Option assumed by Parent shall be determined by multiplying the number of shares of Company Common Stock that were subject to such Company Option immediately prior to the Effective Time by the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; (C) the per share exercise price for the Parent Common Stock issuable upon exercise of each Company Option assumed by Parent shall be determined by dividing the per share exercise price of Company Common Stock subject to such Company Option, 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 (D) any restriction on the exercise of any Company Option assumed by Parent shall continue in full force and effect and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged as a result of the assumption of such Company Option; provided, however, that Parent 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 Parent.

(b) Parent shall file with the SEC, no later than 30 days after the Closing Date, a registration statement on Form S-8, if available for use by Parent, relating to the shares of Parent Common Stock issuable with respect to the Company Options assumed by Parent in accordance with Section 5.4(a).

(c) At the Effective Time, Parent may (if Parent determines that it desires to do so) assume any or all of the Company Option Plans. If Parent elects to assume any Company Option Plan, then, under such Company Option Plan, Parent shall be entitled to grant stock awards, to the extent permissible under applicable Legal Requirements, using the share reserves of such Company Option Plan as of the Effective Time (including any shares returned to such share reserves as a result of the termination of Company Options that are assumed by Parent pursuant to Section 5.4(a)), except that: (i) stock covered by such awards shall be shares of Parent Common Stock; (ii) all references in such Company Option Plan to a number of shares of Company Common Stock shall be deemed amended to refer instead to a number of shares of Parent Common Stock determined by multiplying the number of referenced shares of Company Common Stock by the Exchange Ratio, and rounding the resulting number down to the nearest whole number of shares of Parent Common Stock; and (iii) the Parent Board or a committee thereof shall succeed to the authority and responsibility of the Company Board or any committee thereof with respect to the administration of such Company Option Plan.

61.

(d) Prior to the Effective Time, the Company shall take all action that may be necessary (under the Company Option Plans and otherwise) to effectuate the provisions of this Section 5.4 and to ensure that, from and after the Effective Time, holders of Company Equity Awards have no rights with respect thereto other than those specifically provided in this Section 5.4.

(e) Prior to the Designated Date, the Company shall take all action that may be necessary to: (i) cause any outstanding offering period (or similar period during which Company Common Stock may be purchased) under the Company ESPP to be terminated as of the last business day prior to the Closing Date (the last business day prior to the Closing Date being referred to as the “Designated Date”); (ii) make any pro-rata adjustments that may be necessary to reflect the shortened offering period (or similar period), but otherwise treat such shortened offering period (or similar period) as a fully effective and completed offering period for all purposes under the Company ESPP; (iii) cause the exercise as of the Designated Date of each outstanding purchase right under the Company ESPP; and (iv) provide that no further offering period (or similar period) or purchase period shall commence under the Company ESPP after the date of this Agreement; provided, however, that the actions described in clauses “(i)” through “(iv)” of this sentence shall be conditioned upon the consummation of the Merger. On the Designated Date, the Company shall apply the funds credited as of such date under the Company ESPP within each participant’s payroll withholding account to the purchase of whole shares of Company Common Stock in accordance with the terms of the Company ESPP. Immediately prior to and effective as of the Designated Date (and subject to the consummation of the Merger), the Company shall terminate the Company ESPP.

5.5 Employee Benefits.

(a) Parent agrees that, subject to any necessary transition period and subject to any applicable plan provisions, contractual requirements or Legal Requirements: (i) all employees of the Symyx Corporations who continue employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation after the Effective Time (“Continuing Employees”) shall be eligible to participate in Parent’s health, vacation and 401(k) plans, to substantially the same extent as similarly situated employees of Parent; and (ii) for purposes of determining a Continuing Employee’s eligibility to participate in such plans (but not for purposes of benefit accrual), such Continuing Employee shall receive credit under such plans for his or her years of continuous service with the Symyx Corporations prior to the Effective Time.

(b) Nothing in this Section 5.5 or elsewhere in this Agreement shall be construed to create a right in any Company Associate to employment with Parent, the Surviving Corporation or any other Subsidiary of Parent.

Except for Company Indemnified Persons (as defined in Section 5.6(a)) to the extent of their respective rights pursuant to Section 5.6, no Company Associate, and no Continuing Employee, shall be deemed to be a third party beneficiary of this Agreement. No Parent Associate shall be deemed to be a third party beneficiary of this Agreement.

62.

(c) If requested in writing by Parent at least five days prior to the Closing, the Company shall take (or cause to be taken) all actions necessary or appropriate to terminate, effective no later than the Designated Date, any Company Employee Plan that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code (a “Company 401(k) Plan”). If the Company is required to terminate any Company 401(k) Plan, then the Company shall provide to Parent prior to the Closing Date written evidence of the adoption by the Company Board of resolutions authorizing the termination of such Company 401(k) Plan (the form and substance of which resolutions shall be subject to the prior review and approval of Parent). The Company also shall take, prior to the Effective Time, such other actions in furtherance of terminating such Company 401(k) Plan as Parent may reasonably request.

In addition, Parent shall use commercially reasonable efforts to, or shall cause the Surviving Corporation to use commercially reasonable efforts to: (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Continuing Employees under any Parent Benefit Plan that is a welfare benefit plan in which such Continuing Employees may be eligible to participate after the Effective Time, other than preexisting condition limitations, exclusions or waiting periods that are already in effect with respect to such Continuing Employees and that have not been satisfied or waived as of the Effective Time under any welfare benefit plan maintained for the Continuing Employees immediately prior to the Effective Time; and (ii) provide each Continuing Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any applicable deductible or out-of-pocket requirements under any Parent Benefit Plan that is a welfare plans in which such Continuing Employees may be eligible to participate after the Effective Time.

Prior to the Effective Time, the Company shall not, and shall ensure that its Subsidiaries and the respective Representatives of the Symyx Corporations do not, communicate with any employees of the Symyx Corporations regarding post-Closing employment matters, including post-Closing employee benefits and compensation, without the prior written approval of Parent, which approval shall not be unreasonably withheld.
