1.    Establishment, Purpose and Types of Awards

Endgame Systems, Inc., a Delaware corporation (the “Company”), hereby establishes the Endgame Systems, Inc. Amended and Restated 2010 Stock Incentive Plan (the “Plan”). The purpose of the Plan is to promote the long-term growth and profitability of the Company by (i) providing key people with incentives to improve stockholder value and to contribute to the growth and financial success of the Company through their future services, and (ii) enabling the Company to attract, retain and reward the best-available persons. This Plan is a continuation, and amendment and restatement, of the Company’s 2010 Stock Incentive Plan.

The Plan permits the granting of stock options (including incentive stock options qualifying under Code section 422 and nonstatutory stock options), stock appreciation rights, or other stock-based awards, or any combination of the foregoing.

2.    Definitions

(a)    ”Administrator” means the Board or the committee(s) or officer(s) appointed by the Board that have authority to administer the Plan as provided in Section 3 hereof.

(b)    ”Affiliate” means any entity, whether now or hereafter existing, which controls, is controlled by, or is under common control with, the Company (including, but not limited to, joint ventures, limited liability companies, and partnerships). For this purpose, “control” shall mean ownership of 50% or more of the total combined voting power or value of all classes of stock or interests of the entity, or has the power to direct the management and policies of the entity, by contract or otherwise.

(f)    ”Change in Control” means: (i) the acquisition (other than from the Company) in one or more transactions by any Person, as defined in this Section 2(f), of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) of 50% or more of (A) the then outstanding shares of the securities of the Company, or (B) the combined voting power of the then outstanding securities of the Company entitled to vote generally in the election of directors (the “Company Voting Stock”); (ii) the closing of a sale or other conveyance of all or substantially all of the assets of the Company; or (iii) the effective time of any merger, share exchange, consolidation, or other business combination involving the Company if immediately after such transaction persons who hold a majority of the outstanding voting securities entitled to vote generally in the election of directors of the surviving entity (or the entity owning 100% of such surviving entity) are not persons who, immediately prior to such transaction, held the Company Voting Stock; provided, however, that a Change in Control shall not include any transaction primarily for equity financing purposes or a public offering of capital stock of the Company; and provided, further, that for purposes of any Award or subplan that constitutes a “nonqualified deferred compensation plan,” within the meaning of Code section 409A, the Administrator, in its discretion, may specify a different definition of Change in Control in order to comply with the provisions of Code section 409A. For purposes of this Section 2(f), a “Person” means any individual, entity or group within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended, other than: employee benefit plans sponsored or maintained by the Company and by entities controlled by the Company or an underwriter of the Common Stock in a registered public offering.

(h)    ”Common Stock” means shares of the common stock of the Company, par value of $0.001 per share.

(i)    ”Fair Market Value” means, with respect to a share of the Company’s Common Stock for any purpose on a particular date, the value determined by the Administrator in good faith. However, if the Common Stock is registered under Section 12(b) or 12(g) of the Securities Exchange Act of 1934, as amended, and listed for trading on a national exchange or market, “Fair Market Value” means, as applicable, (i) the closing price quoted on the New York Stock Exchange, the American Stock Exchange, the Nasdaq Global Select Market, or the Nasdaq Global Market; (ii) the last sale price on the relevant date quoted on the Nasdaq Capital Market; (iii) the average of the high bid and low asked prices on the relevant date quoted on the Nasdaq OTC Bulletin Board Service or by the National Quotation Bureau, Inc. or a comparable service as determined in the Administrator’s discretion; or (iv) if the Common Stock is not quoted by any of the above, the average of the closing bid and asked prices on the relevant date furnished by a professional market maker for the Common Stock, or by such other source, selected by the Administrator. If no public trading of the Common Stock occurs

on the relevant date but the shares are so listed, then Fair Market Value shall be determined as of the next preceding date on which trading of the Common Stock did occur. For all purposes under this Plan, the term “relevant date” as used in this Section 2(i) means either the date as of which Fair Market Value is to be determined or the next preceding date on which public trading of the Common Stock occurs, as determined in the Administrator’s discretion.

(j)    ”Grant Agreement” means a written document, including an electronic writing acceptable to the Administrator, memorializing the terms and conditions of an Award granted pursuant to the Plan and which shall incorporate the terms of the Plan.

3.    Administration

(a)    Administration of the Plan. The Plan shall be administered by the Board or by such committee or committees as may be appointed by the Board from time to time. To the extent allowed by applicable state law, the Board by resolution may authorize an officer or officers to grant Awards (other than stock Awards) to any person eligible to participate in the Plan, and, to the extent of such authorization, such officer or officers shall be the Administrator.

(b)    Powers of the Administrator. The Administrator shall have all the powers vested in it by the terms of the Plan, such powers to include authority, in its sole and absolute discretion, to grant Awards under the Plan, prescribe Grant Agreements evidencing such Awards and establish programs for granting Awards.

The Administrator shall have full power and authority to take all other actions necessary to carry out the purpose and intent of the Plan, including, but not limited to, the authority to: (i) determine the eligible persons to whom, and the time or times at which Awards shall be granted; (ii) determine the types of Awards to be granted; (iii) determine the number of shares to be covered by or used for reference purposes for each Award; (iv) impose such terms, limitations, restrictions and conditions upon any such Award as the Administrator shall deem appropriate; (v) modify, amend, extend or renew outstanding Awards, or accept the surrender of outstanding Awards and substitute new Awards; provided, however, that, except as otherwise permitted under Section 7(d) of the Plan, any modification, amendment, extension, renewal or substitution that would materially adversely affect any outstanding Award shall not be made without the consent of the holder, but if any of the foregoing actions results in a change in the tax consequences with respect to an Award such change shall not be considered to be a material adverse affect on the Award; (vi) accelerate or otherwise change the time in which an Award may be exercised or becomes payable and to waive or accelerate the lapse, in whole or in part, of any restriction or condition with respect to such Award, including, but not limited to, any restriction or condition with respect to the vesting or exercisability of an Award following termination of any grantee’s employment or other relationship with the Company; (vii) establish objectives and conditions, if any, for earning Awards and determining whether Awards will be paid with respect to a performance period; and (viii) for any purpose, including but not limited to, qualifying for preferred tax treatment under foreign tax laws or otherwise complying with the regulatory requirements of local or foreign jurisdictions, to establish, amend, modify, administer or terminate sub-plans, and prescribe, amend and rescind rules and regulations relating to such sub-plans.

The Administrator shall have full power and authority, in its sole and absolute discretion, to administer, construe and interpret the Plan, Grant Agreements and all other documents relevant to the Plan and Awards issued thereunder, to establish, amend, rescind and interpret such rules, regulations, agreements, guidelines and instruments for the administration of the Plan and for the conduct of its business as the Administrator deems necessary or advisable, and to correct any defect, supply any omission or reconcile any inconsistency in the Plan or in any Award in the manner and to the extent the Administrator shall deem it desirable to carry it into effect.

(c)    Non-Uniform Determinations. The Administrator’s determinations under the Plan (including without limitation, determinations of the persons to receive Awards, the form, amount and timing of such Awards, the terms and provisions of such Awards and the Grant Agreements evidencing such Awards) need not be uniform and may be made by the Administrator selectively among persons who receive, or are eligible to receive, Awards under the Plan, whether or not such persons are similarly situated.

(d)    Limited Liability. To the maximum extent permitted by law, no member of the Administrator shall be liable for any action taken or decision made in good faith relating to the Plan or any Award thereunder.

(e)    Indemnification. To the maximum extent permitted by law and by the Company’s charter and by-laws, the members of the Administrator shall be indemnified by the Company in respect of all their activities under the Plan.

(f)    Effect of Administrator’s Decision. All actions taken and decisions and determinations made by the Administrator on all matters relating to the Plan pursuant to the powers vested in it hereunder shall be in the Administrator’s sole and absolute discretion and shall be conclusive and binding on all parties concerned, including the Company, its stockholders, any participants in the Plan and any other employee, consultant, or director of the Company, and their respective successors in interest.

4.    Shares Available for the Plan

(a)    Share Reserve. Subject to adjustments as provided in Section 7(d) of the Plan, the shares of Common Stock that may be issued with respect to Awards granted under the Plan shall not exceed an aggregate of 6,065,882 shares of Common Stock. The Company shall reserve such number of shares for Awards under the Plan, subject to adjustments as provided in Section 7(d) of the Plan. If any Award, or portion of an Award, under the Plan expires or terminates unexercised, becomes unexercisable, is settled in cash without delivery of shares of Common Stock, or is forfeited or otherwise terminated, surrendered or canceled as to any shares, or if any shares of Common Stock are repurchased by or surrendered to the Company in connection with any Award (whether or not such surrendered shares were acquired pursuant to any Award), or if any shares are withheld by the Company, the shares subject to such Award and the repurchased, surrendered and withheld shares shall thereafter be available for further Awards under the Plan; provided, however, that any such shares that are surrendered to or repurchased or withheld by the Company in connection with any Award or that are otherwise forfeited after issuance shall not be available for purchase pursuant to incentive stock options intended to qualify under Code section 422.

(b)    Incentive Stock Option Limit. Notwithstanding anything to the contrary in this Section 4 and subject to adjustments as provided in Section 7(d) of the Plan, the shares of Common Stock that may be issued pursuant to the exercise of incentive stock options intended to qualify under Code section 422 shall not exceed an aggregate of 6,065,882 shares of Common Stock.

5.    Participation

Participation in the Plan shall be open to all employees, officers, and directors of, and other individuals (including consultants and advisors) providing bona fide services to or for, the Company, or to any Affiliate of the Company, as may be selected by the Administrator from time to time; provided, however, that nonstatutory stock options and SARs (as defined in Section 6(b) of the Plan) may not be granted to employees, officers, directors, and other individuals (including consultants and advisors) who are providing services only to any “parent” of the Company, as such term is defined in Rule 405 promulgated under the Securities Act of 1933, as amended, unless the stock underlying such Award is treated as “service recipient stock” under Code section 409A because the Awards are granted pursuant to a corporate transaction (such as a spin off transaction) or unless such Awards comply with the distribution requirements of Code section 409A.

6.    Awards

The Administrator, in its sole discretion, establishes the terms of all Awards granted under the Plan. Awards may be granted individually or in tandem with other types of Awards, concurrently with or with respect to outstanding Awards. All Awards are subject to the terms and conditions provided in the Grant Agreement. The Administrator may permit or require a recipient of an Award to defer such individual’s receipt of the payment of cash or the delivery of Common Stock that would otherwise be due to such individual by virtue of the issuance of, exercise of, payment of, or lapse or waiver of restrictions respecting, any Award. If any such payment deferral is required or permitted, the Administrator shall, in its sole discretion, establish rules and procedures for such payment deferrals, subject to the provisions of Code section 409A.

(a)    Stock Options. The Administrator may from time to time grant to eligible participants Awards of incentive stock options as that term is defined in Code section 422 or nonstatutory stock options; provided, however, that Awards of incentive stock options shall be limited to employees of the Company or of any current or hereafter existing “parent corporation” or “subsidiary corporation,” as defined in Code sections 424(e) and (f), respectively, of the Company and any other individuals who are eligible to receive incentive stock options under the provisions of Code section 422. Options intended to qualify as incentive stock options under Code section 422 must have an exercise price at least equal to Fair Market Value as of the date of grant, but nonstatutory stock options may be granted with an exercise price less than Fair Market Value (subject to the provisions of Code section 409A). No stock option shall be an incentive stock option unless so designated by the Administrator at the time of grant or in the Grant Agreement evidencing such stock option.

(b)    Stock Appreciation Rights. The Administrator may from time to time grant to eligible participants Awards of Stock Appreciation Rights (“SAR”). A SAR entitles the grantee to receive, subject to the provisions of the Plan and the Grant Agreement, a payment having an aggregate value equal to the product of (i) the excess of (A) the Fair Market Value on the exercise date of one share of Common Stock over (B) the base price per share specified in the Grant Agreement, times (ii) the number of shares specified by the SAR, or portion thereof, which is exercised. The base price per share specified in the Grant Agreement shall not be less than the lower of the Fair Market Value on the grant date or the exercise price of any tandem stock option Award to which the SAR is related. No SAR shall have a term longer than 10 years duration. Payment by the Company of the amount receivable upon any exercise of a SAR may be made by the delivery of Common Stock or cash, or any combination of Common Stock and cash, as determined in the sole discretion of the Administrator. If upon settlement of the exercise of a SAR a grantee is to receive a portion of such payment in shares of Common Stock, the number of shares shall be determined by dividing such portion by the Fair Market Value of a share of Common Stock on the exercise date. No fractional shares shall be used for such payment and the Administrator shall determine whether cash shall be given in lieu of such fractional shares or whether such fractional shares shall be eliminated.

(c)    Stock Awards. The Administrator may from time to time grant stock Awards to eligible participants in such amounts, on such terms and conditions, and for such consideration, including no consideration or such minimum consideration as may be required by law, as it shall determine. A stock Award may be denominated in Common Stock or other securities, stock-equivalent units, securities or debentures convertible into Common Stock, or any combination of the foregoing and may be paid in Common Stock or other securities, in cash, or in a combination of Common Stock or other securities and cash, all as determined in the sole discretion of the Administrator.

7.    Miscellaneous

(a)    Withholding of Taxes. Grantees and holders of Awards shall pay to the Company or its Affiliate, or make provision satisfactory to the Administrator for payment of, any taxes required to be withheld in respect of Awards under the Plan no later than the date of the event creating the tax liability. The Company or its Affiliate may, in its sole discretion and to the extent permitted by law, deduct any such tax obligations from any payment of any kind otherwise due to the grantee or holder of an Award, including, but not limited to, withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the grantee or holder of such Award in connection with the Award. In the event that payment to the Company or its Affiliate of such tax obligations is made in shares of Common Stock, such shares shall be valued at Fair Market Value on the applicable date for such purposes and shall not exceed in amount the minimum statutory tax withholding obligation.

(b)    Loans. To the extent otherwise permitted by law, the Company or its Affiliate may make or guarantee loans to grantees to assist grantees in exercising Awards and satisfying any withholding tax obligations.

(c)    Transferability. Except as otherwise determined by the Administrator, and in any event in the case of an incentive stock option or a stock appreciation right granted with respect to an incentive stock option, no Award granted under the Plan shall be transferable by a grantee otherwise than by will or the laws of descent and distribution. Unless otherwise determined by the Administrator in accord with the provisions of the immediately preceding sentence, an Award may be exercised during the lifetime of the grantee, only by the grantee or, during the period the grantee is under a legal disability, by the grantee’s guardian or legal representative.

(d)    Adjustments for Corporate Transactions and Other Events.

(A)    accelerate (in part or in whole) the vesting and/or exercisability of such option or other Award;

(B)    unilaterally cancel such option in exchange for whole and/or fractional shares of Common Stock (or for whole shares and cash in lieu of any fractional share) that, in the aggregate, are equal in value to the excess of the Fair Market Value of the shares of Common Stock that could be purchased subject to such option determined as of the effective time of the Change in Control (not taking into account vesting and/or exercisability) over the aggregate exercise price for such shares of Common Stock;

(C)    unilaterally cancel such option in exchange for cash or other property equal in value to the excess of the Fair Market Value of the shares of Common Stock that could be purchased subject to such option determined as of the effective time of the Change in Control (not taking into account vesting and/or exercisability) over the aggregate exercise price for such shares of Common Stock. For purposes of clarity, this payment may be zero ($0) if the value of the property is equal to or less than the exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of the Common Stock in connection with the Change in Control is delayed as a result of escrows, earn outs, holdbacks, or any other contingencies;

(D)    unilaterally cancel such option after providing the holder of such option with (y) an opportunity to exercise such option within a specified period prior to the effective time of the Change in Control, and (z) notice of such opportunity to exercise prior to the commencement of such specified period;

(E)    unilaterally cancel such option and notify the holder of such option of such action, but only if the Fair Market Value of the shares of Common Stock that could be purchased subject to such option determined as of the effective time of the Change in Control (not taking into account vesting and/or exercisability) does not exceed the aggregate exercise price for such shares; and/or

(F)    unilaterally cancel any such option which has not vested and/or which has not become exercisable as of the effective time of the Change in Control.

The Administrator need not take the same action with respect to all Awards or with respect to all holders of such Awards. The Administrator may take different actions with respect to the vested and unvested portions of an Award.

(e)    Substitution of Awards in Mergers and Acquisitions. Awards may be granted under the Plan from time to time in substitution for awards held by employees, officers, consultants or directors of entities who become or are about to become employees, officers, consultants or directors of the Company or an Affiliate as the result of a merger or consolidation of the employing entity with the Company or an Affiliate, or the acquisition by the Company or an Affiliate of the assets or stock of the employing entity. The terms and conditions of any substitute Awards so granted may vary from the terms and conditions set forth herein to the extent that the Administrator deems appropriate at the time of grant to conform the substitute Awards to the provisions of the awards for which they are substituted.

(f)    Other Agreements. As a condition precedent to the grant of any Award under the Plan, the exercise pursuant to such an Award, or to the delivery of certificates for shares issued pursuant to any Award, the Administrator may require the grantee or the grantee’s successor or permitted transferee, as the case may be, to become a party to a stock restriction agreement, shareholders’ agreement, voting agreement, right of first refusal and co-sale agreement or other agreements regarding the Common Stock of the Company in such form(s) as the Administrator may determine from time to time.

(g)    Termination, Amendment and Modification of the Plan. The Board may terminate, amend or modify the Plan or any portion thereof at any time. Except as otherwise determined by the Board, termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

(h)    Non-Guarantee of Employment or Service. Nothing in the Plan or in any Grant Agreement thereunder shall confer any right on an individual to continue in the service of the Company or shall interfere in any way with the right of the Company to terminate such service at any time with or without cause or notice and whether or not such termination results in (i) the failure of any Award to vest; (ii) the forfeiture of any unvested or vested portion of any Award; and/or (iii) any other adverse effect on the individual’s interests under the Plan.

(i)    Compliance with Securities Laws; Listing and Registration. If at any time the Administrator determines that the delivery of Common Stock under the Plan is or may be unlawful under the laws of any applicable jurisdiction, or Federal, state or foreign securities laws, the right to exercise an Award or receive shares of Common Stock pursuant to an Award shall be suspended until the Administrator determines that such delivery is lawful. The

Company shall have no obligation to effect any registration or qualification of the Common Stock under Federal, state or foreign laws. The Company may require that a grantee, as a condition to exercise of an Award, and as a condition to the delivery of any share certificate, make such written representations (including representations to the effect that such person will not dispose of the Common Stock so acquired in violation of Federal, state or foreign securities laws) and furnish such information as may, in the opinion of counsel for the Company, be appropriate to permit the Company to issue the Common Stock in compliance with applicable Federal, state or foreign securities laws. The stock certificates for any shares of Common Stock issued pursuant to this Plan may bear a legend restricting transferability of the shares of Common Stock unless such shares are registered or an exemption from registration is available under the Securities Act of 1933, as amended, and applicable state or foreign securities laws.

(j)    No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company and a grantee or any other person. To the extent that any grantee or other person acquires a right to receive payments from the Company pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company.

(k)    Governing Law. The validity, construction and effect of the Plan, of Grant Agreements entered into pursuant to the Plan, and of any rules, regulations, determinations or decisions made by the Administrator relating to the Plan or such Grant Agreements, and the rights of any and all persons having or claiming to have any interest therein or thereunder, shall be determined exclusively in accordance with applicable federal laws and the laws of the State of Delaware, without regard to its conflict of laws principles.

(l)    409A Savings Clause. The Plan and all Awards granted hereunder are intended to comply with, or otherwise be exempt from, Code section 409A. The Plan and all Awards granted under the Plan shall be administered, interpreted, and construed in a manner consistent with Code section 409A to the extent necessary to avoid the imposition of additional taxes under Code section 409A(a)(1)(B). Should any provision of the Plan, any Award agreement, or any other agreement or arrangement contemplated by the Plan be found not to comply with, or otherwise be exempt from, the provisions of Code section 409A, such provision shall be modified and given effect (retroactively if necessary), in the sole discretion of the Administrator, and without the consent of the holder of the Award, in such manner as the Administrator determines to be necessary or appropriate to comply with, or to effectuate an exemption from, Code section 409A. Notwithstanding anything in the Plan to the contrary, in no event shall the Administrator exercise its discretion to accelerate the payment or settlement of an Award where such payment or settlement constitutes deferred compensation within the meaning of Code section 409A unless, and solely to the extent, that such accelerated payment or settlement is permissible under Treasury Regulation section 1.409A-3(j)(4) or any successor provision.

(m)    Prior Plans. This Plan is the only plan or agreement of the Company with respect to the subject matter hereof and supersedes and replaces all prior plans, agreements and undertakings, both written and oral, with respect to such subject matter.

(n)    Effective Date; Termination Date. The Plan is effective as of the date on which the Plan is adopted by the Board, subject to approval of the stockholders within twelve months before or after such date. No Award shall be granted under the Plan after the close of business on the day immediately preceding the tenth anniversary of the effective date of the Plan, or if earlier, the tenth anniversary of the date this Plan is approved by the stockholders. Subject to other applicable provisions of the Plan, all Awards made under the Plan prior to such termination of the Plan shall remain in effect until such Awards have been satisfied or terminated in accordance with the Plan and the terms of such Awards.

APPENDIX A

PROVISIONS FOR CALIFORNIA RESIDENTS

With respect to Awards granted to California residents prior to a public offering of capital stock of the Company that is effected pursuant to a registration statement filed with, and declared effective by, the Securities and Exchange Commission under the Securities Act of 1933, as amended, and only to the extent required by applicable law, the following provisions shall apply notwithstanding anything in the Plan or a Grant Agreement to the contrary:

1.    With respect to any Award granted in the form of a stock option pursuant to Section 6(a) of the Plan:

(a)    The exercise period shall be no more than 120 months from the date the option is granted.

(b)    The options shall be non-transferable other than by will, by the laws of descent and distribution, or, if and to the extent permitted under the Grant Agreement, to a revocable trust or as permitted by Rule 701 of the Securities Act of 1933, as amended (17 C.F.R. 230.701).

(c)    Unless employment is terminated for “cause” as defined by applicable law, the terms of the Plan or Grant Agreement, or a contract of employment, the right to exercise the option in the event of termination of employment, to the extent that the Award recipient is entitled to exercise on the date employment terminates, will continue until the earlier of the option expiration date, or:

(1)    At least 6 months from the date of termination if termination was caused by death or disability.

(2)    At least 30 days from the date of termination if termination was caused by other than death or disability.

2.    With respect to an Award, granted pursuant to Section 6(c) of the Plan, that provides the Award recipient the right to purchase stock, the Award shall be non-transferable other than by will, by the laws of descent and distribution, or, if and to the extent permitted under the Grant Agreement, to a revocable trust or as permitted by Rule 701 of the Securities Act of 1933, as amended (17 C.F.R. 230.701).

3.    The Plan shall have a termination date of not more than 10 years from the date the Plan is adopted by the Board or the date the Plan is approved by the security holders, whichever is earlier.

4.    Security holders representing a majority of the Company’s outstanding securities entitled to vote must approve the Plan by the later of (a) 12 months after the date the Plan is adopted or (b) 12 months after the granting of any Award to a resident of California. Any option exercised or any securities purchased before security holder approval is obtained must be rescinded if security holder approval is not obtained within the period described in the preceding sentence. Such securities shall not be counted in determining whether such approval is obtained.

5.    At the discretion of the Administrator, the Company may reserve to itself and/or its assignee(s) in the Grant Agreement or any applicable stock restriction agreement a right to repurchase securities held by an Award recipient upon such Award recipient’s termination of employment at any time within six months after such Award recipient’s termination date (or in the case of securities issued upon exercise of an option after the termination date, within six months after the date of such exercise) for cash or cancellation of purchase money indebtedness, at:

(A)    no less than the Fair Market Value of such securities as of the date of the Award recipient’s termination of employment, provided, that such right to repurchase securities terminates when the Company’s securities have become publicly traded; or

(B)    the Award recipient’s original purchase price, provided, that such right to repurchase securities at the original purchase price lapses at the rate of at least 20% of the securities per year over 5 years from the date the option is granted (without respect to the date the option was exercised or became exercisable).

The securities held by an officer, director, manager or consultant of the Company or an affiliate may be subject to additional or greater restrictions.

6.    The Company will provide financial statements to each Award recipient annually during the period such individual has Awards outstanding, or as otherwise required under Section 260.140.46 of Title 10 of the California Code of Regulations. Notwithstanding the foregoing, the Company will not be required to provide such financial statements to Award recipients when the Plan complies with all conditions of Rule 701 of the Securities Act of 1933, as amended (17 C.F.R. 230.701); provided that for purposes of determining such compliance, any registered domestic partner shall be considered a “family member” as that term is defined in Rule 701.

7.    The Plan is intended to comply with Section 25102(o) of the California Corporations Code. Any provision of this Plan which is inconsistent with Section 25102(o), including without limitation any provision of this Plan that is more restrictive than would be permitted by Section 25102(o) as amended from time to time, shall, without further act or amendment by the Board, be reformed to comply with the provisions of Section 25102(o). If at any time the Administrator determines that the delivery of Common Stock under the Plan is or may be unlawful under the laws of any applicable jurisdiction, or federal or state securities laws, the right to exercise an Award or receive shares of Common Stock pursuant to an Award shall be suspended until the Administrator determines that such delivery is lawful. The Company shall have no obligation to effect any registration or qualification of the Common Stock under federal or state laws.

INCENTIVE STOCK OPTION AGREEMENT

UNDER THE

2.    Exercise of Options.

(a)    Exercisability. The Options will become exercisable in accordance with the Exercisability Schedule set forth in the Stock Option Notice, so long as you are in the Service of the Company from the Grant Date through the applicable exercisability dates. Except as otherwise provided by the Administrator or in the Stock Option Notice, none of the Options will become exercisable after your Service with the Company ceases.

(b)    Right to Exercise. You may exercise the Options, to the extent exercisable, at any time on or before 5:00 p.m. Eastern Time on the Expiration Date or the earlier termination of the Options, unless otherwise provided under applicable law. Section 3 below describes certain limitations on exercise of the Options that apply in the event of your death, Total and Permanent Disability, or termination of Service. The Options may be exercised only in multiples of whole Shares and may not be exercised at any one time as to fewer than one hundred Shares (or such lesser number of Shares as to which the Options are then exercisable) unless otherwise agreed to by the Administrator. No fractional Shares will be issued under the Options.

(c)    Exercise Procedure. In order to exercise the Options, you must provide the following items to the Secretary of the Company or his or her delegate before the expiration or termination of the Options:

An exercise will not be effective until the Secretary of the Company or his or her delegate receives all of the foregoing items, and such exercise otherwise is permitted under and complies with all applicable federal, state and foreign securities laws.

- 1 -

(d)    Method of Payment. You may pay the Exercise Price by:

(e)    Agreement to Execute Other Agreements. You agree to execute, as a condition precedent to the exercise of the Options and at any time thereafter, any and all agreements as may be requested by the Administrator that may be common among some or all of the Company’s stockholders, including, without limitation, a stock restriction agreement, shareholders’ agreement, voting agreement, and right of first refusal and co-sale agreement.

(f)    Issuance of Shares upon Exercise. As soon as practicable after exercise of the Options, the Company will deliver a share certificate to you, or deliver Shares electronically or in certificate form to your designated broker on your behalf, for the Shares issued upon exercise. Any share certificates delivered will, unless the Shares are registered or an exemption from registration is available under applicable federal and state law, bear a legend restricting transferability of such Shares and referencing any applicable agreement described in Section 2(e).

3.    Termination of Service.

(a)    Termination of Unexercisable Options. If your Service with the Company ceases for any reason, the Options that are then unexercisable, after giving effect to the exercise acceleration provisions set forth on the Stock Option Notice, if any, will terminate immediately upon such cessation.

(b)    Exercise Period Following Termination of Service. If your Service with the Company ceases for any reason other than discharge for Cause, the Options that are then exercisable, after giving effect to the exercise acceleration provisions set forth on the Stock Option Notice, if any, will terminate upon the earliest of:

(i)    the expiration of 90 days following such cessation, if your Service ceases on account of (1) your termination by the Company other than a discharge for Cause, or (2) your voluntary termination other than for Total and Permanent Disability or death;

(ii)    the expiration of 12 months following such cessation, if your Service ceases on account of your Total and Permanent Disability or death;

- 2 -

(iii)    the expiration of 12 months following your death, if your death occurs during the periods described in clauses (i) or (ii) of this Section 3(b), as applicable; or

(iv)    the Expiration Date.

In the event of your death, the exercisable Options may be exercised by your executor, personal representative, or the person(s) to whom the Options are transferred by will or the laws of descent and distribution.

(c)    Misconduct. The Options will terminate in their entirety, regardless of whether the Options are then exercisable, immediately upon your discharge from Service for Cause, or upon your commission of any of the following acts during the exercise period following your termination of Service: (i) fraud on or misappropriation of any funds or property of the Company, or (ii) your breach of any provision of any employment, non-disclosure, non-competition, non-solicitation, assignment of inventions, employee covenants or other similar agreement executed by you for the benefit of the Company, as determined by the Administrator, which determination will be conclusive.

(d)    Changes in Status. If you cease to be a “common law employee” of the Company but you continue to provide bona fide services to the Company following such cessation in a different capacity, including without limitation as a director, consultant or independent contractor, then a termination of Service shall not be deemed to have occurred for purposes of this Section 3 upon such change in capacity. Notwithstanding the foregoing, the Options shall not be treated as incentive stock options within the meaning of Code section 422 with respect to any exercise that occurs more than three months after such cessation of the common law employee relationship (except as otherwise permitted under Code section 421 or 422). In the event that your Service is with a business, trade or entity that, after the Grant Date, ceases for any reason to be part or an Affiliate of the Company, your Service will be deemed to have terminated for purposes of this Section 3 upon such cessation if your Service does not continue uninterrupted immediately thereafter with the Company or an Affiliate of the Company.

4.    Market Stand-Off Agreement. You agree that following the effective date of a registration statement of the Company filed under the Securities Act of 1933, you, for the duration specified by and to the extent requested by the Company and an underwriter of Common Stock or other securities of the Company, shall not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such securities, whether any such aforementioned transaction is to be settled by delivery of such securities or other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, in each case during the seven days prior to and the 180 days after the effectiveness of any underwritten offering of the Company’s equity securities (or such longer or shorter period as may be requested in writing by the managing underwriter and agreed to in writing by the Company) (the “Market Stand-Off Period”), except as part of such underwritten registration if otherwise permitted. In addition, you agree to execute any further letters, agreements and/or other documents requested by the Company or its underwriters that are consistent with the terms of this Section 4. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Stand-Off Period.

5.    Nontransferability of Options. These Options are nontransferable otherwise than by will or the laws of descent and distribution and during your lifetime, the Options may be exercised only by you or, during the period you are under a legal disability, by your guardian or legal representative. Except as provided above, the Options may not be assigned, transferred, pledged, hypothecated or disposed of in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process.

- 3 -

6.    Qualified Nature of the Options.

(a)    General Status. The Options are intended to qualify as incentive stock option within the meaning of Code section 422 (“Incentive Stock Option”), to the fullest extent permitted by Code section 422, and this Agreement shall be so construed. The Company, however, does not warrant any particular tax consequences of the Options. Code section 422 provides limitations, not set forth in this Agreement, respecting the treatment of the Options as Incentive Stock Options. You should consult with your personal tax advisors in this regard.

(b)    Code Section 422(d) Limitation. Pursuant to Code section 422(d), the aggregate fair market value (determined as of the Grant Date) of shares of Common Stock with respect to which all Incentive Stock Options first become exercisable by you in any calendar year under the Plan or any other plan of the Company (and its parent and subsidiary corporations, within the meaning of Code section 424(e) and (f), as may exist from time to time) may not exceed $100,000 or such other amount as may be permitted from time to time under Code section 422. To the extent that such aggregate fair market value exceeds $100,000 or other applicable amount in any calendar year, such stock options will be treated as nonstatutory stock options with respect to the amount of aggregate fair market value thereof that exceeds the Code section 422(d) limit. For this purpose, the Incentive Stock Options will be taken into account in the order in which they were granted. In such case, the Company may designate the shares of Common Stock that are to be treated as stock acquired pursuant to the exercise of Incentive Stock Options and the shares of Common Stock that are to be treated as stock acquired pursuant to nonstatutory stock options by issuing separate certificates for such shares and identifying the certificates as such in the stock transfer records of the Company.

(c)    Significant Stockholders. Notwithstanding anything in this Agreement or the Stock Option Notice to the contrary, if you own, directly or indirectly through attribution, stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of any of its subsidiaries (within the meaning of Code section 424(f)) on the Grant Date, then the Exercise Price is the greater of (a) the Exercise Price stated on the Stock Option Notice or (b) 110% of the Fair Market Value of the Common Stock on the Grant Date, and the Expiration Date is the last business day prior to the fifth anniversary of the Grant Date.

7.    Withholding of Taxes. At the time the Options are exercised, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll or any other payment of any kind due to you and otherwise agree to make adequate provision for foreign, federal, state and local taxes required by law to be withheld, if any, which arise in connection with the Options (including upon a disqualifying disposition within the meaning of Code section 421(b)). The Company may require you to make a cash payment to cover any withholding tax obligation as a condition of exercise of the Options or issuance of share certificates representing Shares.

The Administrator may, in its sole discretion, permit you to satisfy, in whole or in part, any withholding tax obligation which may arise in connection with the Options either by electing to have the Company withhold from the Shares to be issued upon exercise that number of Shares, or by electing to deliver to the Company already-owned shares, in either case having a Fair Market Value equal to the amount necessary to satisfy the statutory minimum withholding amount due.

8.    Adjustments. The Administrator may make various adjustments to your Options, including adjustments to the number and type of securities subject to the Options and the Exercise Price, in accordance with the terms of the Plan. In the event of any transaction resulting in a Change in Control of the Company, (i) such Options may be terminated, and in such case

- 4 -

you will be permitted, immediately before the Change in Control, to exercise or convert all such Options or you will receive Fair Market Value for any such Options as provided in the Plan, or (ii) provision may be made in connection with the transaction for the continuation or assumption of such Options by, or for the substitution of the equivalent awards of, the surviving or successor entity or a parent thereof. In the event of any transaction resulting in a Change in Control of the Company, the vesting of the outstanding Options under this Agreement shall automatically accelerate as set forth in the Plan or your Stock Option Notice.

9.    Non-Guarantee of Employment or Service Relationship. Nothing in the Plan or this Agreement will alter your at-will or other employment status or other service relationship with the Company, nor be construed as a contract of employment or service relationship between you and the Company, or as a contractual right for you to continue in the employ of, or in a service relationship with, the Company for any period of time, or as a limitation of the right of the Company to discharge you at any time with or without Cause or notice and whether or not such discharge results in the failure of any of the Options to become exercisable or any other adverse effect on your interests under the Plan.

10.    No Rights as a Stockholder. You shall not have any of the rights of a stockholder with respect to the Shares until such Shares have been issued to you upon the due exercise of the Options. No adjustment will be made for dividends or distributions or other rights for which the record date is prior to the date such Shares are issued.

11.    The Company’s Rights. The existence of the Options shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the Company’s assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

12.    Entire Agreement. This Agreement, together with the correlating Stock Option Notice and the Plan, contain the entire agreement between you and the Company with respect to the Option. Any oral or written agreements, representations, warranties, written inducements, or other communications made prior to the execution of this Agreement with respect to the Options shall be void and ineffective for all purposes.

13.    Amendment. This Agreement may be amended from time to time by the Administrator in its discretion; provided, however, that this Agreement may not be modified in a manner that would have a materially adverse effect on the Options or Shares as determined in the discretion of the Administrator, except as provided in the Plan or in a written document signed by you and the Company.

14.    Conformity with Plan. This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan. Any conflict between the terms of this Agreement and the Plan shall be resolved in accordance with the terms of the Plan. In the event of any ambiguity in this Agreement or any matters as to which this Agreement is silent, the Plan shall govern. A copy of the Plan is provided to you with this Agreement.

(c)    “Cause” has the meaning ascribed to such term in the Plan.

(d)    “Company” means Endgame, Inc. and its Affiliates, except where the context otherwise requires. For purposes of determining whether a Change in Control has occurred, Company shall mean only Endgame, Inc.

(e)    “Good Reason” means any material adverse change in your position (including status, offices, titles and reporting requirements), authority, duties or responsibilities (other than a change due to your Total or Permanent Disability or as an accommodation under the Americans With Disabilities Act) which results in a diminution in any material respect in your position, authority, duties, responsibilities or compensation, which diminution continues in time over at least thirty (30) days, such that it constitutes an effective demotion (provided, however, that no diminution of title, position, duties or responsibilities shall be deemed to occur solely because the Company becomes a subsidiary of another corporation or entity or because there has been a change in the reporting hierarchy incident thereto involving you); provided, however, that it shall not constitute Good Reason unless you shall have provided the Company with written notice of its alleged actions constituting Good Reason (which notice shall specify in reasonable detail the particulars of such Good Reason) and Company has not cured any such alleged Good Reason or substantially commenced its effort to cure such breach within 30 days of Company’s receipt of such written notice.

The Administrator may require such proof of Total and Permanent Disability as the Administrator in its sole discretion deems appropriate and the Administrator’s good faith determination as to whether you are totally and permanently disabled will be final and binding on all parties concerned.

(j)    “You”; “Your” means the recipient of the award of Options as reflected on the Stock Option Notice. Whenever the Agreement refers to “you” under circumstances where the provision should logically be construed, as determined by the Administrator, to apply to your estate, personal representative, or beneficiary to whom the Options may be transferred by will or by the laws of descent and distribution, the word “you” shall be deemed to include such person.

EXERCISE FORM

Administrator of Endgame, Inc. 2010 Amended and Restated Stock Incentive Plan

c/o Office of the Corporate Secretary

Endgame, Inc.

[                    ]

[                    ]

Gentlemen:

I hereby exercise the Options granted to me on             ,         , by Endgame, Inc. (the “Company”), subject to all the terms and provisions of the applicable grant agreement and of the Endgame, Inc. 2010 Amended and Restated Stock Incentive Plan (the “Plan”), and notify you of my desire to purchase                  shares of Common Stock of the Company at a price of $         per share pursuant to the exercise of said Options.

This will confirm my understanding with respect to the shares to be issued to me by reason of this exercise of the Options (the shares to be issued pursuant hereto shall be collectively referred to hereinafter as the “Shares”) as follows:

(a)    I am purchasing the Shares for my own account for investment only, and not with a view to, or for sale in connection with, any distribution of the Shares in violation of the Securities Act of 1933 (the “Securities Act”), or any rule or regulation under the Securities Act.

(b)    I understand that the Shares are being issued without registration under the Securities Act, in reliance upon one or more exemptions contained in the Securities Act, and such reliance is based in part on the above representation. I also understand that the Company is not obligated to comply with the registration requirements of the Securities Act or with the requirements for an exemption under Regulation A under the Securities Act for my benefit.

(c)    I have had such opportunity as I deemed adequate to obtain from representatives of the Company such information as is necessary to permit me to evaluate the merits and risks of my investment in the Company.

(d)    I have sufficient experience in business, financial and investment matters to be able to evaluate the risks involved in the purchase of the Shares and to make an informed investment decision with respect to such purchase.

(e)    I can afford a complete loss of the value of the Shares and am able to bear the economic risk of holding such Shares for an indefinite period.

(f)    I understand that (i) the Shares have not been registered under the Securities Act and are “restricted securities” within the meaning of Rule 144 under the Securities Act; (ii) the Shares cannot be sold, transferred or otherwise disposed of unless they are subsequently registered under the Securities Act or an exemption from registration is then available and, therefore, they may need to be held indefinitely; and (iii) there is now no registration statement on file with the Securities and Exchange Commission with respect to any stock of the Company and the Company has no obligation or current intention to register the Shares under the Securities Act. As a condition to any transfer of the Shares, I understand that the Company may require an opinion of counsel satisfactory to the Company to the effect that such transfer does not require registration under the Securities Act or any state securities law.

(g)    I understand that the certificates for the Shares to be issued to me will bear a legend substantially as follows:

The shares of stock represented by this certificate are subject to restrictions on transfer, an option to purchase and a market stand-off agreement set forth in one or more agreements between the corporation and the registered owner of this certificate (or his predecessor in interest), and no transfer of such shares may be made without compliance with such agreements. A copy of those agreements is available for inspection at the office of the corporation upon appropriate request and without charge.

The securities represented by this stock certificate have not been registered under the Securities Act of 1933 (the “Act”) or applicable state securities laws (the “State Acts”), and shall not be sold, pledged, hypothecated, donated, or otherwise transferred (whether or not for consideration) by the holder except upon the issuance to the corporation of a favorable opinion of its counsel and/or submission to the corporation of such other evidence as may be satisfactory to counsel for the corporation, to the effect that any such transfer shall not be in violation of the Act and the State Acts.

The Company will issue appropriate stop transfer instructions to its transfer agent.

(h)    I am a party to one or more agreements with the Company, including a grant agreement, pursuant to which I have agreed to certain restrictions on the transferability of the Shares and other matters relating thereto.

In the event that your Service is with a business, trade or entity that, after the Grant Date, ceases for any reason to be part or an Affiliate of the Company, your Service will be deemed to have terminated for purposes of this Section 3 upon such cessation if your Service does not continue uninterrupted immediately thereafter with the Company or an Affiliate of the Company.

4.    Market Stand-Off Agreement. You agree that following the effective date of a registration statement of the Company filed under the Securities Act of 1933, you, for the duration specified by and to the extent requested by the Company and an underwriter of Common Stock or other securities of the Company, shall not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of such securities, whether any such aforementioned transaction is to be settled by delivery of such securities or other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, in each case during the seven days prior to and the 180 days after the effectiveness of any underwritten offering of the Company’s equity securities (or such longer or shorter period as may be requested in writing by the managing underwriter and agreed to in writing by the Company) (the “Market Stand-Off Period”), except as part of such underwritten registration if otherwise permitted. In addition, you agree to execute any further letters, agreements and/or other documents requested by the Company or its underwriters that are consistent with the terms of this Section 4. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Stand-Off Period.

5.    Nontransferability of Options. These Options are nontransferable otherwise than by will or the laws of descent and distribution and during your lifetime, the Options may be exercised only by you or, during the period you are under a legal disability, by your guardian or legal representative. Except as provided above, the Options may not be assigned, transferred, pledged, hypothecated or disposed of in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process.

6.    Nonqualified Nature of the Options. The Options are not intended to qualify as incentive stock options within the meaning of Code section 422, and this Agreement shall be so construed. You hereby acknowledge that, upon exercise of the Options, you will recognize compensation income in an amount equal to the excess of the then Fair Market Value of the Shares over the Exercise Price and must comply with the provisions of Section 7 of this Agreement with respect to any tax withholding obligations that arise as a result of such exercise.

7.    Withholding of Taxes. At the time the Options are exercised, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll or any other payment of any kind due to you and otherwise agree to make adequate

provision for foreign, federal, state and local taxes required by law to be withheld, if any, which arise in connection with the Options. The Company may require you to make a cash payment to cover any withholding tax obligation as a condition of exercise of the Options or issuance of share certificates representing Shares.

The Administrator may, in its sole discretion, permit you to satisfy, in whole or in part, any withholding tax obligation which may arise in connection with the Options either by electing to have the Company withhold from the Shares to be issued upon exercise that number of Shares, or by electing to deliver to the Company already-owned shares, in either case having a Fair Market Value equal to the amount necessary to satisfy the statutory minimum withholding amount due.

8.    Adjustments. The Administrator may make various adjustments to your Options, including adjustments to the number and type of securities subject to the Options and the Exercise Price, in accordance with the terms of the Plan. Section 7(d)(iii) of the Plan describes actions that the Administrator may take with respect to outstanding Options upon a Change in Control.

9.    Non-Guarantee of Employment or Service Relationship. Nothing in the Plan or this Agreement will alter your at-will or other employment status or other service relationship with the Company, nor be construed as a contract of employment or service relationship between you and the Company, or as a contractual right for you to continue in the employ of, or in a service relationship with, the Company for any period of time, or as a limitation of the right of the Company to discharge you at any time with or without Cause or notice and whether or not such discharge results in the failure of any of the Options to become exercisable or any other adverse effect on your interests under the Plan.

10.    No Rights as a Stockholder. You shall not have any of the rights of a stockholder with respect to the Shares until such Shares have been issued to you upon the due exercise of the Options. No adjustment will be made for dividends or distributions or other rights for which the record date is prior to the date such Shares are issued.

11.    The Company’s Rights. The existence of the Options shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or other stocks with preference ahead of or convertible into, or otherwise affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of the Company’s assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

12.    Entire Agreement. This Agreement, together with the correlating Stock Option Notice and the Plan, contain the entire agreement between you and the Company with respect to the Option. Any oral or written agreements, representations, warranties, written inducements, or other communications made prior to the execution of this Agreement with respect to the Options shall be void and ineffective for all purposes.

13.    Amendment. This Agreement may be amended from time to time by the Administrator in its discretion; provided, however, that this Agreement may not be modified in a manner that would have a materially adverse effect on the Options or Shares as determined in the discretion of the Administrator, except as provided in the Plan or in a written document signed by you and the Company.

14.    Conformity with Plan. This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan. Any conflict between the terms of this Agreement and the Plan shall be resolved in accordance with the terms of the Plan. In the event of any ambiguity in this Agreement or any matters as to which this Agreement is silent, the Plan shall govern. A copy of the Plan is provided to you with this Agreement.

EXERCISE FORM

Administrator of Endgame, Inc. 2010 Amended and Restated Stock Incentive Plan

c/o Office of the Corporate Secretary

Endgame, Inc.

[                    ]

[                    ]

Gentlemen:

I hereby exercise the Options granted to me on             , 20    , by Endgame, Inc. (the “Company”), subject to all the terms and provisions of the applicable grant agreement and of the Endgame, Inc. 2010 Amended and Restated Stock Incentive Plan (the “Plan”), and notify you of my desire to purchase                  shares of Common Stock of the Company at a price of $         per share pursuant to the exercise of said Options.

This will confirm my understanding with respect to the shares to be issued to me by reason of this exercise of the Options (the shares to be issued pursuant hereto shall be collectively referred to hereinafter as the “Shares”) as follows:

(a)    I am purchasing the Shares for my own account for investment only, and not with a view to, or for sale in connection with, any distribution of the Shares in violation of the Securities Act of 1933 (the “Securities Act”), or any rule or regulation under the Securities Act.

(b)    I understand that the Shares are being issued without registration under the Securities Act, in reliance upon one or more exemptions contained in the Securities Act, and such reliance is based in part on the above representation. I also understand that the Company is not obligated to comply with the registration requirements of the Securities Act or with the requirements for an exemption under Regulation A under the Securities Act for my benefit.

(c)    I have had such opportunity as I deemed adequate to obtain from representatives of the Company such information as is necessary to permit me to evaluate the merits and risks of my investment in the Company.

(d)    I have sufficient experience in business, financial and investment matters to be able to evaluate the risks involved in the purchase of the Shares and to make an informed investment decision with respect to such purchase.

(e)    I can afford a complete loss of the value of the Shares and am able to bear the economic risk of holding such Shares for an indefinite period.

(f)    I understand that (i) the Shares have not been registered under the Securities Act and are “restricted securities” within the meaning of Rule 144 under the Securities Act; (ii) the Shares cannot be sold, transferred or otherwise disposed of unless they are subsequently registered under the

Securities Act or an exemption from registration is then available and, therefore, they may need to be held indefinitely; and (iii) there is now no registration statement on file with the Securities and Exchange Commission with respect to any stock of the Company and the Company has no obligation or current intention to register the Shares under the Securities Act. As a condition to any transfer of the Shares, I understand that the Company may require an opinion of counsel satisfactory to the Company to the effect that such transfer does not require registration under the Securities Act or any state securities law.

(g)    I understand that the certificates for the Shares to be issued to me will bear a legend substantially as follows:

The shares of stock represented by this certificate are subject to restrictions on transfer, an option to purchase and a market stand-off agreement set forth in one or more agreements between the corporation and the registered owner of this certificate (or his predecessor in interest), and no transfer of such shares may be made without compliance with such agreements. A copy of those agreements is available for inspection at the office of the corporation upon appropriate request and without charge.

The securities represented by this stock certificate have not been registered under the Securities Act of 1933 (the “Act”) or applicable state securities laws (the “State Acts”), and shall not be sold, pledged, hypothecated, donated, or otherwise transferred (whether or not for consideration) by the holder except upon the issuance to the corporation of a favorable opinion of its counsel and/or submission to the corporation of such other evidence as may be satisfactory to counsel for the corporation, to the effect that any such transfer shall not be in violation of the Act and the State Acts.

The Company will issue appropriate stop transfer instructions to its transfer agent.

(h)    I am a party to one or more agreements with the Company, including a grant agreement, pursuant to which I have agreed to certain restrictions on the transferability of the Shares and other matters relating thereto.

Total Amount Enclosed: $
