ARTICLE IV

CONVERSION OF SECURITIES

Section 4.1 Conversion of ESS Delaware Capital Stock. At the Effective Time of the Merger, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, ESS Delaware or any holder of any capital stock of any of ESS Delaware, Parent or Merger Sub:

(a) Conversion of ESS Delaware Common Stock. Each ESS Delaware Share, except for Exception Shares, shall be converted into the right to receive $1.64, payable to the holder thereof in cash, without interest (the “Merger Consideration”). From and after the Effective Time, all such ESS Delaware Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist. Except with respect to Exception Shares, each holder of a certificate representing any such ESS Delaware Share shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such certificate in accordance with Section 4.2, without interest thereon.

(b) Merger Sub Common Stock. Each issued and outstanding share of common stock of Merger Sub, par value $0.0001 per share, shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.0001 per share, of the Surviving Corporation.

Each share of ESS Delaware Common Stock owned by Parent, Merger Sub or any of their respective wholly owned subsidiaries shall be cancelled and shall cease to exist, and no consideration shall be delivered in exchange therefor. Each share of ESS Delaware Common Stock held by ESS Delaware or any Subsidiary of ESS Delaware (or held in the treasury of ESS Delaware) shall be cancelled and shall cease to exist, and no consideration shall be delivered in exchange therefor. Each Dissenting Share shall be treated as provided in Section 4.3.

(d) Adjustment to Merger Consideration. The Merger Consideration shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Common Stock or ESS Delaware Common Stock), cash dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Common Stock or ESS

Delaware Common Stock occurring on or after the date hereof and prior to the Effective Time of the Reincorporation Merger or the Effective Time of the Merger, as applicable.

Section 4.2 Payment and Exchange of Certificates.

(a) Paying Agent. Parent or Merger Sub shall designate a bank or trust company to act as the payment agent in connection with the Merger (the “Paying Agent”). At the Effective Time of the Merger, Parent or Merger Sub shall cause to be deposited with the Paying Agent the aggregate Merger Consideration. Such funds shall be invested by the Paying Agent as directed by Parent, in its sole discretion, pending payment thereof by the Paying Agent to the holders of the ESS Delaware Shares entitled thereto. Earnings from such investments shall be the sole and exclusive property of Parent, and no part of such earnings shall accrue to the benefit of holders of ESS Delaware Shares.

(b) Exchange Procedures. Promptly after the Effective Time of the Merger, the Paying Agent shall mail to each holder of record as of the Effective Time of the Merger of a certificate or certificates which immediately prior to the Effective Time represented outstanding ESS Delaware Shares (each such certificate, a “Certificate”) and whose ESS Delaware Shares were converted pursuant to Section 4.1(a) into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to Certificates shall pass, only upon delivery of Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for effecting the surrender of Certificates in exchange for payment of the Merger Consideration. Upon surrender of a Certificate for cancellation in accordance with the instructions set forth in the letter of transmittal to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each ESS Delaware Share formerly represented by such Certificate and the Certificate so surrendered shall forthwith be cancelled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition precedent of payment that (x) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and (y) the Person requesting such payment shall have paid any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered and shall have established to the satisfaction of the Surviving Corporation that such Tax either has been paid or is not required to be paid. As of the Effective Time of the Merger, and until surrendered as contemplated by this Section 4.2, each Certificate (except with respect to those ESS Delaware Shares represented thereby that are Exception Shares) shall be deemed at any time after the Effective Time of the Merger to represent only the right to receive the Merger Consideration in cash as contemplated by this Section 4.2, without interest thereon.

(c) Transfer Books; No Further Ownership Rights in ESS Delaware Capital Stock. At the Effective Time of the Merger, the stock transfer books of ESS Delaware shall be closed and thereafter there shall be no further registration of transfers of ESS Delaware Shares on the records of ESS Delaware. From and after the Effective Time of the Merger, the holders of Certificates outstanding immediately prior to the Effective Time of the Merger shall cease to have any rights with respect to such ESS Delaware Shares except as otherwise provided for

herein, including, without limitation, Section 4.3 hereof, or by applicable law. If, after the Effective Time of the Merger, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Article IV.

(d) Termination of Fund; No Liability. At any time following six months after the Effective Time of the Merger, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed (or for which disbursement is pending subject only to the Paying Agent’s routine administrative procedures) to holders of Certificates, and thereafter such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation or the Paying Agent shall be liable to any holder of a Certificate for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Withholding Rights. Parent, Merger Sub, the Surviving Corporation and the Paying Agent, as the case may be, shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of ESS Delaware Shares such amounts that Parent, Merger Sub, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the extent that amounts are so withheld by Parent, Merger Sub, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by Parent, Merger Sub, the Surviving Corporation or the Paying Agent.

(f) Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to Section 4.1 hereof; provided, however, that Parent may, in its discretion and as a condition precedent to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Paying Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

Section 4.3 Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, if any stockholder of ESS Delaware Common Stock (each, a “Dissenting Stockholder”) shall demand to be paid the “fair value” of its shares of ESS Delaware Common Stock (“Dissenting Share”), as provided in Section 262(d)(2) of the DGCL, such Dissenting Shares shall not be converted into or exchangeable for the right to receive the Merger Consideration (except as provided in this Section 4.3) and shall entitle such Dissenting Stockholder only to be paid the “fair value” of such Dissenting Shares, in accordance with Section 262 of the DGCL, unless and until such

Dissenting Stockholder (a) withdraws (in accordance with Section 262(k) of the DGCL) or (b) effectively loses the right to dissent and receive the “fair value” of such Dissenting Shares under Section 262 of the DGCL. ESS Delaware shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment of “fair value” of Dissenting Shares prior to the Effective Time of the Merger. ESS Delaware shall give Parent prompt notice of any written demand by a Dissenting Stockholder to be paid the “fair value” of its Dissenting Shares received by ESS Delaware prior to the Effective Time of the Merger, any attempted withdrawals of such demands and any other instruments received by ESS Delaware relating to stockholders’ rights of appraisal, and Parent shall have the right to participate in all negotiations and proceedings with respect to any such demand or instrument. If any Dissenting Stockholder shall have effectively withdrawn (in accordance with Section 262(k) of the DGCL) or otherwise lost its right to dissent and receive the “fair value” of its Dissenting Shares, then as of the later of the Effective Time of the Merger or the occurrence of such event, the Dissenting Shares held by such Dissenting Stockholder shall be cancelled and converted into and represent solely the right to receive (upon the surrender of the Certificate representing such share) the Merger Consideration, without interest thereon, in accordance with Section 4.1.

(b) Notwithstanding any other provision of this Agreement to the contrary, any legal proceeding made or brought by any of the current or former shareholders of the Company asserting that ESS Delaware is required to purchase for cash at their fair market value any Dissenting Shares (and that have not lost their right to dissent) and that are owned by such shareholder may be considered for purposes of determining whether a Company Material Adverse Effect has occurred hereunder.

Section 4.4 Treatment of ESS Delaware Options and Other Equity Awards.

(a) At the Effective Time of the Merger, each ESS Delaware Option, by virtue of the Merger and without any further action on the part of any holder of any outstanding ESS Delaware Option, that is outstanding immediately prior to the Effective Time of the Merger, whether vested or unvested, exercisable or unexercisable, shall be deemed automatically converted into the right to receive an amount in cash equal to the product obtained by multiplying (x) the aggregate number of shares of ESS Delaware Common Stock subject to such ESS Delaware Option and (y) the excess, if any, of the Merger Consideration less the exercise price per share of ESS Delaware Common Stock subject to such ESS Delaware Option (the “Option Consideration”) after which it shall be cancelled and extinguished.

(b) The Company and Delaware Merger Sub, and, after the Reincorporation Merger, ESS Delaware, shall take all necessary actions, including obtaining any required consents from holders of outstanding Company Options and ESS Delaware Options, respectively, necessary to effect the transactions described in Sections 2.2 and 4.4(a) above pursuant to the terms of the applicable Company Stock Plans and agreements evidencing the Company Options and the ESS Delaware Options, as applicable. All amounts payable pursuant to Section 4.4(a) shall be paid without interest in accordance with this Agreement. Any payments made pursuant to this Section 4.4 shall be net of all applicable withholding Taxes that Parent, Merger Sub, the Surviving Corporation and the Paying Agent, as the case may be, shall be required to deduct and withhold from the relevant Option Consideration or Merger

Consideration under the Code, the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the extent that amounts are so withheld by Parent, Merger Sub, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by Parent, Merger Sub, the Surviving Corporation or the Paying Agent.

ARTICLE V

REPRESENTATIONS AND
WARRANTIES OF THE COMPANY

Except as set forth in the Company’s disclosure schedule delivered to Parent prior to the execution of this Agreement (the “Company Disclosure Schedule”) or (ii) any Company SEC Documents filed by the Company with the United States Securities and Exchange Commission (the “SEC”) after January 1, 2007, the Company represents and warrants to Parent and Merger Sub that the statements contained in this Article V are correct and complete as of the date of this Agreement. Each disclosure set forth in the Company Disclosure Schedule is identified by reference to, or has been grouped under a heading referring to, a specific section of this Agreement and disclosure made pursuant to any section thereof shall be deemed to be disclosed on each of the other sections of the Company Disclosure Schedule to the extent the applicability of the disclosure to such other section is reasonably apparent on its face from the disclosure made.

Section 5.1 Organization.

(a) The Company and each Subsidiary of the Company, including Delaware Merger Sub (each, a “Company Subsidiary”). is a corporation or other legal entity duly organized, validly existing and in good standing (with respect to jurisdictions which recognize such concept) under the laws of the jurisdiction in which it is organized and has the requisite corporate or other power, as the case may be, and authority to conduct its business as now being conducted, except, as to Company Subsidiaries, for those jurisdictions where the failure to be so organized, existing or in good standing would not, individually or in the aggregate, reasonably be expected to be material to the Company and the Company Subsidiaries taken as a whole. The Company and each of the Company Subsidiaries is duly qualified or licensed to do business and is in good standing (with respect to jurisdictions which recognize such concept) in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification or licensing necessary, except for those jurisdictions where the failure to be so qualified or licensed or to be in good standing would not, individually or in the aggregate, reasonably be expected to be material to the Company and the Company Subsidiaries taken as a whole. The Company has made available to Parent complete and correct copies of the articles of incorporation and bylaws of the Company and the similar organizational documents of each Company Subsidiary, and all amendments thereto, as currently in effect. Neither the Company nor any Company Subsidiary is in violation of its organizational or governing documents.

(b) Subsidiaries. Each outstanding share of capital stock or other Equity Interest of each Company Subsidiary is owned, directly or indirectly, by the Company and is duly authorized, validly issued, fully paid, nonassessable and free of preemptive rights and is held by the Company or a Company Subsidiary free and clear of all Liens, except for Permitted Liens (as defined in Section 5.14). There are no outstanding options, warrants, purchase rights, subscription rights, conversion rights, exchange rights or other agreements, contracts or commitments that could require any Company Subsidiary to issue, sell or otherwise cause to become outstanding any of its capital stock. Other than the Company Subsidiaries, the Company does not directly or indirectly beneficially own any Equity Interests in any other Person except for non-controlling investments made in the ordinary course of business in entities which are not individually or in the aggregate material to the Company and the Company Subsidiaries as a whole.

Section 5.2 Capitalization.

(a) The authorized capital stock of the Company consists of 100,000,000 shares of Common Stock and (ii) 10,000,000 shares of preferred stock, no par value (the “Preferred Stock”).

All of the outstanding shares of the Company’s capital stock are, and all Common Stock which may be issued pursuant to the ESPP and the exercise of outstanding Company Options will be, when issued in accordance with the terms thereof, duly authorized, validly issued, fully paid and non-assessable, free of preemptive rights. Except for issuances of Common Stock pursuant to Company Options described in the first sentence of Section 5.2(b) and issuances of Common Stock pursuant to the ESPP, since its initial public offering, the Company has not issued any Common Stock or designated or issued any shares of Preferred Stock. There are no bonds, debentures, notes or other indebtedness having general voting rights (or convertible into securities having such rights) (“Voting Debt”) of the Company or any Company Subsidiary issued and outstanding. Other than the Company Options described in the first sentence of Section 5.2(b) and the rights outstanding under the ESPP, there are no Equity Interests or outstanding contractual obligations of the Company or any Company Subsidiary to repurchase, redeem or otherwise acquire any Common Stock or any capital stock of, or other Equity Interests in, the Company or any Company Subsidiary or to provide funds to make any investment (in the form of a loan, capital contribution or otherwise) in the Company or any Company Subsidiary. No Company Subsidiary owns any Common Stock.

(b) All of such Company Options have been granted to employees, consultants and directors of the Company and the Company Subsidiaries in the ordinary course of business pursuant to the Company Stock Plans. Section 5.2(b) of the Company Disclosure Schedule sets forth a listing of all outstanding Company Options as of February 21, 2008 and (i) the date of their grant and the portion of which that is vested as of February 21, 2008 and if applicable, the exercise price therefor, (ii) the date upon which each Company Option would normally be expected to expire absent termination of employment or other acceleration, and (iii)

(c) Each Company Option that is designated as an “incentive stock option” is intended to qualify as an “incentive stock option” under the Code. Each grant of a Company Option was duly authorized no later than the date on which the grant of such Company Option was by its terms to be effective (the “Grant Date”) by all necessary corporate action, including, as applicable, approval by the Board of Directors of the Company (or a duly constituted and authorized committee thereof) and any required shareholder approval by the necessary number of votes or written consents, and: (i) each such grant was made in accordance with the terms of the applicable Company Stock Plan, the Exchange Act and all other applicable laws and the rules of NASDAQ; (ii) the per share exercise price of each Company Option was equal to the fair market value of a share of Common Stock on the applicable Grant Date; and (iii) each such grant was properly accounted for in accordance with GAAP (as defined in Section 5.6(b)) in the financial statements (including the related notes) of the Company and disclosed in the Company SEC Documents (as defined in Section 5.6(a)) in accordance with the Exchange Act and all other applicable laws.

(d) Section 5.2(d) of the Company Disclosure Schedule sets forth the maximum number of shares of Common Stock that could be purchased with accumulated payroll deductions under the ESPP at the close of business on last day of current offering/purchase period (assuming the fair market value of a share of Common Stock on such date is equal to $1.64 per share and payroll deductions continue at the rate in effect on the date of this Agreement).

(f) There are no voting trusts or other agreements to which the Company or any Company Subsidiary is a party with respect to the voting of the Common Stock or any capital stock of, or other equity interest of the Company or any of the Company Subsidiaries. Neither the Company nor any Company Subsidiary has granted any preemptive rights, anti-dilutive rights or rights of first refusal or similar rights.

No payment or benefit which has been, will or may be made by the Company or any Company Subsidiary with respect to any current or former employee located in the United States in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated by this Agreement would fail to be deductible under Section 162(m) of the Code. Neither this Agreement (or the consummation of the transactions contemplated by this Agreement) nor any other agreement, plan, arrangement or other contract between the Company or any Company Subsidiary and an employee or other service provider that, considered individually or considered collectively with any other such agreements, plans, arrangements or other contracts, will give rise directly or indirectly to the payment of any amount that would be characterized as an “excess parachute payment” within the meaning of Section 280G(b)(1) of the Code.

(g) Correct and complete copies have been delivered or made available to Parent by the Company of all Benefit Plans (including all amendments and attachments thereto); all insurance contracts or other funding arrangements to the degree applicable; the most recent annual information filings (Form 5500) and annual financial reports for those Benefit Plans (where required); the most recent determination letter from the Internal Revenue Service (where required); all material written agreements and contracts relating to each Benefit Plan, including administrative service agreements and group insurance contracts; and the most recent summary plan descriptions for the Benefit Plans (where required) and in respect of Benefit Plans, the most recent actuarial valuation and any subsequent valuation or funding advice (where required, including draft valuations).

No Governmental Authority has any ownership interest in any Owned Company IP, and neither Company nor its Subsidiaries use or have used any funding, facilities, or personnel of any Governmental Authority in connection with the creation of the Owned Company IP in a manner that could give rise to an ownership interest in the Owned Company IP in favor of such Governmental Authority.

Except as otherwise set forth in this Section 11.2, in the event of a termination of this Agreement by either the Company or Parent as provided in Section 11.1, this Agreement shall forthwith become void and there shall be no liability or obligation on the part of Parent, Merger Sub, the Company or Delaware Merger Sub hereunder; provided, however, that the provisions of this Section 11.2, Sections 8.2(b), 11.3, 11.4 and Article XII shall remain in full force and effect and survive any termination of this Agreement. In no event shall any party be liable for punitive damages.

Section 11.4 Company Termination Fee.

(a) If this Agreement is terminated by the Company pursuant to Section 11.1(c)(ii), or by Parent pursuant to Section 11.1(d) but only in a case where the Company has breached its obligations and covenants in Section 7.3 by affirmatively soliciting a Takeover Proposal, then the Company shall pay to Parent (or as directed by Parent), by wire transfer of same day funds, $1,981,000 plus reimbursement of Parent’s and its affiliates’ reasonable expenses incurred in connection with the transactions contemplated by this Agreement up to, but not in excess of, $500,000 (collectively, the “Company Termination Fee”), as promptly as practicable (and, in any event, within two (2) business days following such termination). If this Agreement is terminated by either the Company or Parent pursuant to Section 11.1(b)(i) or by Parent pursuant to Section 11.1(d)(ii), then, in the event that, (a) at any time after the date of this

Agreement and prior to the occurrence of the action or event that gave rise to Parent’s right to terminate pursuant to Section 11.1(b)(i) or Section 11.1(d)(ii), as applicable, any Third Party shall have publicly made, proposed, communicated or disclosed an intention to make a bona fide Takeover Proposal, which bona fide Takeover Proposal was not retracted or rescinded prior to the occurrence of the action or event that gave rise to Parent’s right to terminate pursuant to Section 11.1(b)(i) or Section 11.1(d)(ii), as applicable, and (b) within nine (9) months of the termination of this Agreement, the Company enters into a definitive agreement with any Third Party with respect to a Takeover Proposal or any Takeover Proposal is consummated by such Third Party, then the Company shall pay, or cause to be paid, to Parent, by wire transfer of same day funds, the Company Termination Fee, such payment to be made upon the consummation of such Takeover Proposal. For purposes of this Section 11.4(a), each reference in the definition of Takeover Proposal to “20 percent (20%)” will be deemed to be references to “50 percent (50%).”

(b) If paid, the Company Termination Fee shall be the sole and exclusive remedy of Parent, Merger Sub and their affiliates against the Company, any Company Subsidiary and any Company Representative for any loss or damage suffered as a result of the breach of any representation, warranty or covenant contained in this Agreement by the Company, any Company Subsidiary or any Company Representative and the failure of the Reincorporation Merger or the Merger to be consummated and, upon payment of the Company Termination Fee in accordance with Section 11.4(a), none of the Company, any Company Subsidiary or any Company Representative shall have further liability or obligation to Parent, Merger Sub or any other Person relating to or arising out of this Agreement or the transactions contemplated by this Agreement. For the avoidance of doubt, in no event shall the Company be obligated to pay, or cause to be paid, the Company Termination Fee on more than one occasion.

(c) The Company acknowledges that the agreements contained in this Section 11.4 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, Parent and Merger Sub would not enter into this Agreement. If the Company fails to pay the Company Termination Fee when due, and, in order to obtain such payment Parent commences a suit which results in a judgment against the Company for all or any portion of the Company Termination Fee, the Company shall pay to Parent its reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) in connection with such suit.

Whenever the words “include”, “includes” or “including” are used in this Agreement they shall be deemed to be followed by the words “without limitation.” As used in this Agreement, the term “affiliates” shall have the meaning set forth in Rule 12b-2 of the Exchange Act. All references to this Agreement shall be deemed to include references to the “agreement of merger” contained herein (as such term is used in the CCC). The table of contents and headings set forth in this Agreement are for convenience of reference purposes only and shall not affect or be deemed to affect in any way the meaning or interpretation of this Agreement or any term or provision hereof. When reference is made herein to a Person, such reference shall be deemed to include all direct and indirect Subsidiaries of such Person unless otherwise indicated or the context otherwise requires. Unless otherwise indicated, all references herein to the Subsidiaries of a Person shall be deemed to include all direct and indirect Subsidiaries of such Person unless otherwise indicated or the context otherwise requires.

Section 12.7 Counterparts. This Agreement may be executed manually or by facsimile by the parties hereto, in any number of counterparts, each of which shall be considered one and the same agreement and shall become effective when a counterpart hereof shall have been signed by each of the parties and delivered to the other parties.

Section 12.8 Entire Agreement; No Third-Party Beneficiaries. This Agreement (including the Company Disclosure Schedule) and the Confidentiality Agreement:

(a) constitute the entire agreement among the parties with respect to the subject matter hereof and thereof and supersede all other prior agreements (except that the Confidentiality Agreement shall be amended so that until the termination of this Agreement in accordance with Section 11.1 hereof, Parent and Merger Sub shall be permitted to take the action contemplated by this Agreement, including the making of any proposals as contemplated by Section 7.3) and understandings, both written and oral, among the parties or any of them with respect to the subject matter hereof and thereof, and

(b) except as provided in Section 8.5, are not intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

Section 12.9 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Reincorporation Merger and the Merger is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the Reincorporation Merger and the Merger are fulfilled to the extent possible.

Section 12.10 Governing Law; Jurisdiction.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to conflicts of laws principles that would result in the application of the law of any other state, except to the extent that mandatory principles of law require the application of the laws of the State of California.

(b) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Chancery Court of the State of Delaware, or, if no such state court has proper jurisdiction, any Federal court of the United States of America sitting in the State of Delaware, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, and each of the parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in such courts, (ii) agrees that any claim in respect of any such action or proceeding may be heard and determined in such Delaware State court or, if no such state court has proper jurisdiction, in such Federal court, (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any such Delaware State court or Federal court, and (iv) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such Delaware State court or Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 12.3. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. Each party hereto agrees not to commence any legal proceedings relating to or arising out of this Agreement or the transactions contemplated by this Agreement in any jurisdiction or courts other than as provided herein.

Section 12.11 Assignment.

(a) This Agreement shall not be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties, except that Merger Sub may assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to (i) Parent, (ii) to Parent and one or more direct or indirect

wholly owned Subsidiaries of Parent or (iii) to one or more direct or indirect wholly owned Subsidiaries of Parent. Subject to the preceding sentence, but without relieving any party hereto of any obligation hereunder, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Notwithstanding anything to the contrary contained herein, Parent, Merger Sub and their affiliates shall have the right to collaterally assign in whole or in part this Agreement and any ancillary agreements or documents related to the transactions contemplated by this Agreement and any of their respective rights thereunder as security to one or more lenders or purchasers of debt securities who, in each case, are being granted a collateral interest in this Agreement or any ancillary agreements or documents related to the transactions contemplated by this Agreement.

(b) Notwithstanding the foregoing, at the Effective Time of the Reincorporation Merger, ESS Delaware shall, by operation of law, succeed to all of the rights and obligations of each of the Company and Delaware Merger Sub hereunder, without any further action by any party to this Agreement and for all purposes hereunder shall be a party hereto.

Section 12.12 Enforcement; Remedies. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that the parties hereto shall be entitled seek an injunction or injunctions to prevent breaches of this Agreement and to specifically enforce the terms hereof, this being in addition to any other remedy to which they are entitled at law or in equity. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.
