ITEM 9. UNDERTAKINGS

1. The undersigned registrant hereby undertakes:

(a) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

          (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the “Securities Act”);

          (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

          (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference herein.

     (b) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     (c) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

2.

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Jose, State of California, on June 19, 2007.

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection with the filing by eBay Inc. (the “Company”) of a Registration Statement on Form S-8 (the “Registration Statement”) with the Securities and Exchange Commission covering the offering of up to an aggregate of 192,899 shares of the Company’s common stock, $0.001 par value (the “Shares”), issuable or reserved for issuance pursuant to the StumbleUpon, Inc. 2006 Stock Plan (the “Plan”).

In connection with this opinion, we have examined the Registration Statement and related Prospectus, the Company’s Amended and Restated Certificate of Incorporation and Bylaws and such other documents, records, certificates, memoranda and other instruments as we deem necessary as a basis for this opinion. We have assumed the genuineness and authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as copies thereof, and the due execution and delivery of all documents where due execution and delivery are a prerequisite to the effectiveness thereof.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Shares, when sold and issued in accordance with the Plan, the Registration Statement and the related Prospectus, will be validly issued, fully paid, and nonassessable.

We consent to the filing of this opinion as an exhibit to the Registration Statement.

Very truly yours,

Cooley Godward Kronish LLP

StumbleUpon, inc. 2006 stock plan

SECTION 1. ESTABLISHMENT AND PURPOSE.

     The purpose of the Plan is to offer selected persons an opportunity to acquire a proprietary interest in the success of the Company, or to increase such interest, by purchasing Shares of the Company’s Stock. The Plan provides both for the direct award or sale of Shares and for the grant of Options to purchase Shares. Options granted under the Plan may include Nonstatutory Options as well as ISOs intended to qualify under Section 422 of the Code.

     Capitalized terms are defined in Section 12.

SECTION 2. ADMINISTRATION.

     (a) Committees of the Board of Directors. The Plan may be administered by one or more Committees. Each Committee shall consist of one or more members of the Board of Directors who have been appointed by the Board of Directors. Each Committee shall have such authority and be responsible for such functions as the Board of Directors has assigned to it. If no Committee has been appointed, the entire Board of Directors shall administer the Plan. Any reference to the Board of Directors in the Plan shall be construed as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular function.

     (b) Authority of the Board of Directors. Subject to the provisions of the Plan, the Board of Directors shall have full authority and discretion to take any actions it deems necessary or advisable for the administration of the Plan. All decisions, interpretations and other actions of the Board of Directors shall be final and binding on all Purchasers, all Optionees and all persons deriving their rights from a Purchaser or Optionee.

SECTION 3. ELIGIBILITY.

     (a) General Rule. Only Employees, Outside Directors and Consultants shall be eligible for the grant of Nonstatutory Options or the direct award or sale of Shares. Only Employees shall be eligible for the grant of ISOs.

     (b) Ten-Percent Stockholders. A person who owns more than 10% of the total combined voting power of all classes of outstanding stock of the Company, its Parent or any of its Subsidiaries shall not be eligible for designation as an Optionee or Purchaser unless (i) the Exercise Price is at least 110% of the Fair Market Value of a Share on the date of grant, (ii) the Purchase Price (if any) is at least 100% of the Fair Market Value of a Share and (iii) in the case of an ISO, such ISO by its terms is not exercisable after the expiration of five years from the date of grant. For purposes of this Subsection (b), in determining stock ownership, the attribution rules of Section 424(d) of the Code shall be applied.

SECTION 4. STOCK SUBJECT TO PLAN.

     (a) Basic Limitation. Not more than 591,105 Shares may be issued under the Plan (subject to Subsection (b) below and Section 8). The number of Shares that are subject to Options or other rights outstanding at any time under the Plan shall not exceed the number of

Shares that then remain available for issuance under the Plan. The Company, during the term of the Plan, shall at all times reserve and keep available sufficient Shares to satisfy the requirements of the Plan. Shares offered under the Plan may be authorized but unissued Shares or treasury Shares.

     (b) Additional Shares. In the event that Shares previously issued under the Plan are reacquired by the Company, such Shares shall be added to the number of Shares then available for issuance under the Plan. In the event that an outstanding Option or other right for any reason expires or is canceled, the Shares allocable to the unexercised portion of such Option or other right shall be added to the number of Shares then available for issuance under the Plan.

SECTION 5. TERMS AND CONDITIONS OF AWARDS OR SALES.

     (a) Stock Purchase Agreement. Each award or sale of Shares under the Plan (other than upon exercise of an Option) shall be evidenced by a Stock Purchase Agreement between the Purchaser and the Company. Such award or sale shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Purchase Agreement. The provisions of the various Stock Purchase Agreements entered into under the Plan need not be identical.

     (b) Duration of Offers and Nontransferability of Rights. Any right to acquire Shares under the Plan (other than an Option) shall automatically expire if not exercised by the Purchaser within 30 days after the grant of such right was communicated to the Purchaser by the Company. Such right shall not be transferable and shall be exercisable only by the Purchaser to whom such right was granted.

     (c) Purchase Price. The Purchase Price of Shares to be offered under the Plan shall not be less than 85% of the Fair Market Value of such Shares, and a higher percentage may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors shall determine the Purchase Price at its sole discretion. The Purchase Price shall be payable in a form described in Section 7.

     (d) Withholding Taxes. As a condition to the purchase of Shares, the Purchaser shall make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with such purchase.

     (e) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares awarded or sold under the Plan shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the applicable Stock Purchase Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of a Purchaser who is not an officer of the Company, an Outside Director or a Consultant:

     (i) Any right to repurchase the Purchaser’s Shares at the original Purchase Price (if any) upon termination of the Purchaser’s Service shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the award or sale of the Shares;

2

     (ii) Any such right may be exercised only for cash or for cancellation of indebtedness incurred in purchasing the Shares; and

     (iii) Any such right may be exercised only within 90 days after the termination of the Purchaser’s Service.

SECTION 6. TERMS AND CONDITIONS OF OPTIONS.

     (a) Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company. The Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Option Agreement. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical.

     (b) Number of Shares. Each Stock Option Agreement shall specify the number of Shares that are subject to the Option and shall provide for the adjustment of such number in accordance with Section 8. The Stock Option Agreement shall also specify whether the Option is an ISO or a Nonstatutory Option.

     (c) Exercise Price. Each Stock Option Agreement shall specify the Exercise Price. The Exercise Price of an ISO shall not be less than 100% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b). The Exercise Price of a Nonstatutory Option shall not be less than 85% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b). Subject to the preceding two sentences, the Exercise Price under any Option shall be determined by the Board of Directors at its sole discretion. The Exercise Price shall be payable in a form described in Section 7.

     (d) Exercisability. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. No Option shall be exercisable unless the Optionee has delivered an executed copy of the Stock Option Agreement to the Company. In the case of an Optionee who is not an officer of the Company, an Outside Director or a Consultant, an Option shall become exercisable at least as rapidly as 20% per year over the five-year period commencing on the date of grant. Subject to the preceding sentence, the Board of Directors shall determine the exercisability provisions of the Stock Option Agreement at its sole discretion. All of an Optionee’s Options shall become exercisable in full if Section 8(b)(iv) applies.

     (e) Basic Term. The Stock Option Agreement shall specify the term of the Option. The term shall not exceed 10 years from the date of grant, and a shorter term may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors at its sole discretion shall determine when an Option is to expire.

3

     (f) Termination of Service (Except by Death). If an Optionee’s Service terminates for any reason other than the Optionee’s death, then the Optionee’s Options shall expire on the earliest of the following occasions:

     (i) The expiration date determined pursuant to Subsection (e) above;

     (ii) The date three months after the termination of the Optionee’s Service for any reason other than Disability, or such later date as the Board of Directors may determine; or

     (iii) The date six months after the termination of the Optionee’s Service by reason of Disability, or such later date as the Board of Directors may determine.

The Optionee may exercise all or part of the Optionee’s Options at any time before the expiration of such Options under the preceding sentence, but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result of the termination). The balance of such Options shall lapse when the Optionee’s Service terminates. In the event that the Optionee dies after the termination of the Optionee’s Service but before the expiration of the Optionee’s Options, all or part of such Options may be exercised (prior to expiration) by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result of the termination).

     (g) Leaves of Absence. For purposes of Subsection (f) above, Service shall be deemed to continue while the Optionee is on a bona fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for this purpose is expressly required by the terms of such leave or by applicable law (as determined by the Company).

     (h) Death of Optionee. If an Optionee dies while the Optionee is in Service, then the Optionee’s Options shall expire on the earlier of the following dates:

     (i) The expiration date determined pursuant to Subsection (e) above; or

     (ii) The date 12 months after the Optionee’s death, or such later date as the Board of Directors may determine.

All or part of the Optionee’s Options may be exercised at any time before the expiration of such Options under the preceding sentence by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that such Options had become exercisable before the Optionee’s death (or became exercisable as a result of the death) and the underlying Shares had vested before the Optionee’s death (or vested as a result of the Optionee’s death). The balance of such Options shall lapse when the Optionee dies.

4

     (i) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares issued upon exercise of an Option shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the applicable Stock Option Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of an Optionee who is not an officer of the Company, an Outside Director or a Consultant:

     (i) Any right to repurchase the Optionee’s Shares at the original Exercise Price upon termination of the Optionee’s Service shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the option grant;

     (ii) Any such right may be exercised only for cash or for cancellation of indebtedness incurred in purchasing the Shares; and

     (iii) Any such right may be exercised only within 90 days after the later of (A) the termination of the Optionee’s Service or (B) the date of the option exercise.

     (j) Transferability of Options. An Option shall be transferable by the Optionee only by (i) a beneficiary designation, (ii) a will or (iii) the laws of descent and distribution, except as provided in the next sentence. If the applicable Stock Option Agreement so provides, a Nonstatutory Option shall also be transferable by gift or domestic relations order to a Family Member of the Optionee. An ISO may be exercised during the lifetime of the Optionee only by the Optionee or by the Optionee’s guardian or legal representative.

     (k) Withholding Taxes. As a condition to the exercise of an Option, the Optionee shall make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with such exercise. The Optionee shall also make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with the disposition of Shares acquired by exercising an Option.

     (l) No Rights as a Stockholder. An Optionee, or a transferee of an Optionee, shall have no rights as a stockholder with respect to any Shares covered by the Optionee’s Option until such person becomes entitled to receive such Shares by filing a notice of exercise and paying the Exercise Price pursuant to the terms of such Option.

     (m) Modification, Extension and Assumption of Options. Within the limitations of the Plan, the Board of Directors may modify, extend or assume outstanding Options or may accept the cancellation of outstanding Options (whether granted by the Company or another issuer) in return for the grant of new Options for the same or a different number of Shares and at the same or a different Exercise Price. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair the Optionee’s rights or increase the Optionee’s obligations under such Option.

SECTION 7. PAYMENT FOR SHARES.

     (a) General Rule. The entire Purchase Price or Exercise Price of Shares issued under the Plan shall be payable in cash or cash equivalents at the time when such Shares are purchased, except as otherwise provided in this Section 7.

     (b) Surrender of Stock. At the discretion of the Board of Directors, all or any part of the Exercise Price may be paid by surrendering, or attesting to the ownership of, Shares that are already owned by the Optionee. Such Shares shall be surrendered to the Company in good form for transfer and shall be valued at their Fair Market Value on the date when the Option is exercised. The Optionee shall not surrender, or attest to the ownership of, Shares in payment of the Exercise Price if such action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to the Option for financial reporting purposes.

     (c) Services Rendered. At the discretion of the Board of Directors, Shares may be awarded under the Plan in consideration of services rendered to the Company, a Parent or a Subsidiary prior to the award.

     (d) Promissory Note. At the discretion of the Board of Directors, all or a portion of the Exercise Price or Purchase Price (as the case may be) of Shares issued under the Plan may be paid with a full-recourse promissory note. However, the par value of the Shares, if newly issued, shall be paid in cash or cash equivalents. The Shares shall be pledged as security for payment of the principal amount of the promissory note and interest thereon. The interest rate payable under the terms of the promissory note shall not be less than the minimum rate (if any) required to avoid the imputation of additional interest under the Code. Subject to the foregoing, the Board of Directors (at its sole discretion) shall specify the term, interest rate, amortization requirements (if any) and other provisions of such note.

     (e) Exercise/Sale. To the extent that a Stock Option Agreement so provides, and if Stock is publicly traded, payment may be made all or in part by the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities broker approved by the Company to sell Shares and to deliver all or part of the sales proceeds to the Company in payment of all or part of the Exercise Price and any withholding taxes.

     (f) Exercise/Pledge. To the extent that a Stock Option Agreement so provides, and if Stock is publicly traded, payment may be made all or in part by the delivery (on a form prescribed by the Company) of an irrevocable direction to pledge Shares to a securities broker or lender approved by the Company, as security for a loan, and to deliver all or part of the loan proceeds to the Company in payment of all or part of the Exercise Price and any withholding taxes.

SECTION 8. ADJUSTMENT OF SHARES.

     (a) Capitalization Adjustments. In the event that any dividend or other distribution, reorganization, merger, consolidation, combination, repurchase, or exchange of Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Stock (other than an Equity Restructuring) occurs such that an adjustment is determined by the Board (in its sole discretion) to be appropriate in order to prevent dilution or

6

enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Board shall, in such manner as it may deem equitable, adjust the number and class of Stock which may be delivered under the Plan, the exercise price per share and the number of shares covered by each Option which has not been exercised, and the numerical limits of Sections 4(a).

     (b) Mergers and Consolidations. In the event that the Company is a party to a merger or consolidation, all outstanding Options shall be subject to the agreement of merger or consolidation. Such agreement shall provide for one or more of the following:

     (i) The continuation of such outstanding Options by the Company (if the Company is the surviving corporation).

     (ii) The assumption of such outstanding Options by the surviving corporation or its parent in a manner that complies with Section 424(a) of the Code (whether or not such Options are ISOs).

     (iii) The substitution by the surviving corporation or its parent of new options for such outstanding Options in a manner that complies with Section 424(a) of the Code (whether or not such Options are ISOs).

     (iv) Full exercisability of such outstanding Options and full vesting of the Shares subject to such Options, followed by the cancellation of such Options. The full exercisability of such Options and full vesting of the Shares subject to such Options may be contingent on the closing of such merger or consolidation. The Optionees shall be able to exercise such Options during a period of not less than five full business days preceding the closing date of such merger or consolidation, unless the Board of Directors determines in good faith that (A) a shorter period is required to permit a timely closing of such merger or consolidation and (B) such shorter period still offers the Optionees a reasonable opportunity to exercise such Options. Any exercise of such Options during such period may be contingent on the closing of such merger or consolidation.

     (v) The cancellation of such outstanding Options and a payment to the Optionees equal to the excess of (A) the Fair Market Value of the Shares subject to such Options (whether or not such Options are then exercisable or such Shares are then vested) as of the closing date of such merger or consolidation over (B) their Exercise Price. Such payment shall be made in the form of cash, cash equivalents, or securities of the surviving corporation or its parent with a Fair Market Value equal to the required amount. Such payment may be made in installments and may be deferred until the date or dates when such Options would have become exercisable or such Shares would have vested. Such payment may be subject to vesting based on the Optionee’s continuing Service, provided that the vesting schedule shall not be less favorable to the Optionees than the schedule under which such Options would have become exercisable or such Shares would have vested. If the Exercise Price of the Shares subject to such Options exceeds the Fair Market Value of such Shares, then such Options may be cancelled without making a payment to the Optionees. For purposes of this Paragraph (v), the Fair Market Value of any security shall be determined without regard to any vesting conditions that may apply to such security.

7

     (c) Reservation of Rights. Except as provided in this Section 8, an Optionee or Purchaser shall have no rights by reason of (i) any subdivision or consolidation of shares of stock of any class, (ii) the payment of any dividend or (iii) any other increase or decrease in the number of shares of stock of any class. Any issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or Exercise Price of Shares subject to an Option. The grant of an Option pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

     (d) Equity Restructuring Adjustments. In connection with the occurrence of any Equity Restructuring, and notwithstanding anything to the contrary in Sections 8(a) and 8(b) the number and type of securities subject to each outstanding Option and the exercise price or grant price thereof will be equitably adjusted by the Board. The adjustments provided under this Section 8(d) shall be nondiscretionary and shall be final and binding on the affected Optionee and the Company.

SECTION 9. SECURITIES LAW REQUIREMENTS.

     (a) General. Shares shall not be issued under the Plan unless the issuance and delivery of such Shares comply with (or are exempt from) all applicable requirements of law, including (without limitation) the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, state securities laws and regulations, and the regulations of any stock exchange or other securities market on which the Company’s securities may then be traded.

     (b) Financial Reports. The Company each year shall furnish to Optionees, Purchasers and stockholders who have received Stock under the Plan its balance sheet and income statement, unless such Optionees, Purchasers or stockholders are key Employees whose duties with the Company assure them access to equivalent information. Such balance sheet and income statement need not be audited.

SECTION 10. NO RETENTION RIGHTS.

     Nothing in the Plan or in any right or Option granted under the Plan shall confer upon the Purchaser or Optionee any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining the Purchaser or Optionee) or of the Purchaser or Optionee, which rights are hereby expressly reserved by each, to terminate his or her Service at any time and for any reason, with or without cause.

SECTION 11. DURATION AND AMENDMENTS.

     (a) Term of the Plan. The Plan, as set forth herein, shall become effective on the date of its adoption by the Board of Directors, subject to the approval of the Company’s stockholders. If the stockholders fail to approve the Plan within 12 months after its adoption by the Board of Directors, then any grants, exercises or sales that have already occurred under the Plan shall be rescinded and no additional grants, exercises or sales shall thereafter be made under the Plan. The Plan shall terminate automatically 10 years after the later of (i) its adoption by the Board of Directors or (ii) the most recent increase in the number of Shares reserved under Section 4 that was approved by the Company’s stockholders. The Plan may be terminated on any earlier date pursuant to Subsection (b) below.

     (b) Right to Amend or Terminate the Plan. The Board of Directors may amend, suspend or terminate the Plan at any time and for any reason; provided, however, that any amendment of the Plan shall be subject to the approval of the Company’s stockholders if it (i) increases the number of Shares available for issuance under the Plan (except as provided in Section 8) or (ii) materially changes the class of persons who are eligible for the grant of ISOs. Stockholder approval shall not be required for any other amendment of the Plan. If the stockholders fail to approve an increase in the number of Shares reserved under Section 4 within 12 months after its adoption by the Board of Directors, then any grants, exercises or sales that have already occurred in reliance on such increase shall be rescinded and no additional grants, exercises or sales shall thereafter be made in reliance on such increase.

     (c) Effect of Amendment or Termination. No Shares shall be issued or sold under the Plan after the termination thereof, except upon exercise of an Option granted prior to such termination.
