Incorporation of Documents by Reference Calpine Corporation (the "Registrant") hereby incorporates by reference into this Registration Statement the following documents previously filed with the Securities and Exchange Commission (the "SEC"): (a) The Registrant's Prospectus filed with the SEC pursuant to Rule 424(b) of the Securities Act of 1933, as amended (the "1933 Act"), in connection with Registration Statement No. 333-07497 on Form S-1, filed with the SEC on July 3, 1996, and the amendments thereto, in which there is set forth audited financial statements for the Registrant's fiscal year ended December 31, 1995; and (b) The Registrant's Quarterly Reports on Form 10-Q for the fiscal quarters ended June 30, 1996 and September 30, 1996, filed with the SEC on August 14, 1996 and November 14, 1996, respectively. (c) The Registrant's Registration Statement No. 00-112079 on Form 8-A filed with the SEC on August 20, 1996 pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the "1934 Act"), in which there is described the terms, rights and provisions applicable to the Registrant's outstanding Common Stock. All reports and definitive proxy or information statements filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of this Registration Statement and prior to the filing of a post-effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold shall be deemed to be incorporated by reference into this Registration Statement and to be a part hereof from the date of filing of such documents. Any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any subsequently filed document which also is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement. Item 4. Description of Securities Not Applicable. Item 5. Interests of Named Experts and Counsel Not Applicable. 4 Item 6. Indemnification of Directors and Officers The Registrant's Certificate of Incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that a director of a corporation will not be personally liable for monetary damages for breach of such individual's fiduciary duties as a director except for liability (i) for any breach of such director's duty of loyalty to the corporation, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which a director derives an improper personal benefit. The Registrant's Bylaws provide that the Registrant will indemnify its directors and may indemnify its officers, employees and other agents to the full extent permitted by law. The Registrant believes that indemnification under its Bylaws covers at least negligence and gross negligence on the part of an indemnified party and permits the Registrant to advance expenses incurred by an indemnified party in connection with the defense of any action or proceeding arising out of such party's status or service as a director, officer, employee or other agent of the Registrant upon an undertaking by such party to repay such advances if it is ultimately determined that such party is not entitled to indemnification. The Registrant has entered into separate indemnification agreements with each of its directors and officers. These agreements require the Registrant, among other things, to indemnify such director or officer against expenses (including attorneys' fees), judgments, fines and settlements (collectively, "Liabilities") paid by such individual in connection with any action, suit or proceeding arising out of such individual's status or service as a director or officer of the Registrant (other than Liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest) and to advance expenses incurred by such individual in connection with any proceeding against such individual with respect to which such individual may be entitled to indemnification by the Registrant. The Registrant believes that its Certificate of Incorporation and Bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. At present the Registrant is not aware of any pending litigation or proceeding involving any director, officer, employee or agent of the Registrant where indemnification will be required or permitted. The Registrant is not aware of any threatened litigation or proceeding that might result in a claim for such indemnification. Item 7. Exemption from Registration Claimed Not Applicable.

Item 9. Undertakings A. The undersigned Registrant hereby undertakes: (1) 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 1933 Act, (ii) to reflect in the prospectus any facts or events arising after the effective date of this 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 this Registration Statement and (iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are incorporated by reference into this Registration Statement; (2) that for the purpose of determining any liability under the 1933 Act each such post- II-3. 6 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; and (3) 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 Registrant's 1996 Stock Incentive Plan and/or Employee Stock Purchase Plan. B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the 1933 Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is incorporated by reference into this 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. C. Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers, or controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the 1933 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 1933 Act and will be governed by the final adjudication of such issue. II-4. 7 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 this 15th day of November, 1996.

PURPOSE OF THE PLAN This 1996 Stock Incentive Plan is intended to promote the interests of Calpine Corporation, a Delaware corporation, by providing eligible persons with the opportunity to acquire a proprietary interest, or otherwise increase their proprietary interest, in the Corporation as an incentive for them to remain in the service of the Corporation. Capitalized terms shall have the meanings assigned to such terms in the attached Appendix. II. STRUCTURE OF THE PLAN A. The Plan shall be divided into five separate equity programs: - the Discretionary Option Grant Program under which eligible persons may, at the discretion of the Plan Administrator, be granted options to purchase shares of Common Stock, - the Salary Investment Option Grant Program under which eligible employees may elect to have a portion of their base salary invested each year in special option grants, - the Stock Issuance Program under which eligible persons may, at the discretion of the Plan Administrator, be issued shares of Common Stock directly, either through the immediate purchase of such shares or as a bonus for services rendered the Corporation (or any Parent or Subsidiary), - the Automatic Option Grant Program under which eligible non- employee Board members shall automatically receive option grants at periodic intervals to purchase shares of Common Stock, and - the Director Fee Option Grant Program under which non- employee Board members may elect to have all or any portion of their annual retainer fee otherwise payable in cash applied to a special option grant. 2 B. The provisions of Articles One and Seven shall apply to all equity programs under the Plan and shall govern the interests of all persons under the Plan. III. ADMINISTRATION OF THE PLAN A. Prior to the Section 12 Registration Date, the Discretionary Option Grant and Stock Issuance Programs shall be administered by the Board. Beginning with the Section 12 Registration Date, the Primary Committee shall have sole and exclusive authority to administer the Discretionary Option Grant and Stock Issuance Programs with respect to Section 16 Insiders and shall have sole and exclusive authority to administer the Salary Investment Option Grant Program with respect to all eligible individuals. B. Administration of the Discretionary Option Grant and Stock Issuance Programs with respect to all other persons eligible to participate in those programs may, at the Board's discretion, be vested in the Primary Committee or a Secondary Committee, or the Board may retain the power to administer those programs with respect to all such persons. The members of the Secondary Committee may be Board members who are Employees eligible to receive discretionary option grants or direct stock issuances under the Plan or any other stock option, stock appreciation, stock bonus or other stock plan of the Corporation (or any Parent or Subsidiary). C. Members of the Primary Committee or any Secondary Committee shall serve for such period of time as the Board may determine and may be removed by the Board at any time. The Board may also at any time terminate the functions of any Secondary Committee and reassume all powers and authority previously delegated to such committee. D. Each Plan Administrator shall, within the scope of its administrative functions under the Plan, have full power and authority (subject to the provisions of the Plan) to establish such rules and regulations as it may deem appropriate for proper administration of the Discretionary Option Grant, Salary Investment Option Grant and Stock Issuance Programs and to make such determinations under, and issue such interpretations of, the provisions of such programs and any outstanding options or stock issuances thereunder as it may deem necessary or advisable. Decisions of the Plan Administrator within the scope of its administrative functions under the Plan shall be final and binding on all parties who have an interest in the Discretionary Option Grant, Salary Investment Option Grant and Stock Issuance Programs under its jurisdiction or any option or stock issuance thereunder. E. Service on the Primary Committee or the Secondary Committee shall constitute service as a Board member, and members of each such committee shall accordingly be entitled to full indemnification and reimbursement as Board members for their service on such committee. No member of the Primary Committee or the Secondary 2. 3 Committee shall be liable for any act or omission made in good faith with respect to the Plan or any option grants or stock issuances under the Plan. F. Administration of the Automatic Option Grant and Director Fee Option Grant Programs shall be self-executing in accordance with the terms of those programs, and no Plan Administrator shall exercise any discretionary functions with respect to any option grants or stock issuances made under those programs. IV. ELIGIBILITY A. The persons eligible to participate in the Discretionary Option Grant and Stock Issuance Programs are as follows: (i) Employees, (ii) non-employee members of the Board or the board of directors of any Parent or Subsidiary, and (iii) consultants and other independent advisors who provide services to the Corporation (or any Parent or Subsidiary). B. Only Employees who are Section 16 Insiders or other highly compensated individuals shall be eligible to participate in the Salary Investment Option Grant Program. C. Each Plan Administrator shall, within the scope of its administrative jurisdiction under the Plan, have full authority to determine, (i) with respect to the option grants under the Discretionary Option Grant Program, which eligible persons are to receive option grants, the time or times when such option grants are to be made, the number of shares to be covered by each such grant, the status of the granted option as either an Incentive Option or a Non-Statutory Option, the time or times when each option is to become exercisable, the vesting schedule (if any) applicable to the option shares and the maximum term for which the option is to remain outstanding and (ii) with respect to stock issuances under the Stock Issuance Program, which eligible persons are to receive stock issuances, the time or times when such issuances are to be made, the number of shares to be issued to each Participant, the vesting schedule (if any) applicable to the issued shares and the consideration for such shares. D. The Plan Administrator shall have the absolute discretion either to grant options in accordance with the Discretionary Option Grant Program or to effect stock issuances in accordance with the Stock Issuance Program. E. The individuals who shall be eligible to participate in the Automatic Option Grant Program shall be limited to (i) those individuals serving as non-employee 3. 4 Board members on the Underwriting Date who have not previously received a stock option grant from the Corporation, (ii) those individuals who first become non-employee Board members after the Underwriting Date, whether through appointment by the Board or election by the Corporation's stockholders, and (iii) those individuals who continue to serve as non-employee Board members at one or more Annual Stockholders Meetings held after the Underwriting Date. A non-employee Board member who has previously been in the employ of the Corporation (or any Parent or Subsidiary) shall not be eligible to receive an option grant under the Automatic Option Grant Program at the time he or she first becomes a non-employee Board member, but shall be eligible to receive periodic option grants under the Automatic Option Grant Program while he or she continues to serve as a non-employee Board member. F. All non-employee Board members shall be eligible to participate in the Director Fee Option Grant Program. V. STOCK SUBJECT TO THE PLAN A. The stock issuable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Corporation on the open market. The maximum number of shares of Common Stock initially reserved for issuance over the term of the Plan shall not exceed 4,041,858 shares. Such authorized share reserve is comprised of (i) the number of shares which remain available for issuance, as of the Plan Effective Date, under the Predecessor Plan as last approved by the Corporation's stockholders, including the shares subject to the outstanding options to be incorporated into the Plan and the additional shares which would otherwise be available for future grant, plus (ii) an additional increase of 1,444,935 shares authorized by the Board but subject to stockholder approval prior to the Section 12 Registration Date. B. The number of shares of Common Stock available for issuance under the Plan shall automatically increase on the first trading day of each calendar year during the term of the Plan, beginning with the 1997 calendar year, by an amount equal to one percent (1%) of the shares of Common Stock outstanding on the last trading day of the immediately preceding calendar year. No Incentive Options may be granted on the basis of the additional shares of Common Stock resulting from such annual increases. C. No one person participating in the Plan may receive options, separately exercisable stock appreciation rights and direct stock issuances for more than 500,000 shares of Common Stock in the aggregate per calendar year, beginning with the 1996 calendar year. D. Shares of Common Stock subject to outstanding options (including options incorporated into this Plan from the Predecessor Plan) shall be available for subsequent issuance under the Plan to the extent those options expire or terminate for any reason prior to exercise in full. Unvested shares issued under the Plan and subsequently cancelled or repurchased by the Corporation, at the original issue price paid per share, 4. 5 pursuant to the Corporation's repurchase rights under the Plan shall be added back to the number of shares of Common Stock reserved for issuance under the Plan and shall accordingly be available for reissuance through one or more subsequent option grants or direct stock issuances under the Plan. However, should the exercise price of an option under the Plan be paid with shares of Common Stock or should shares of Common Stock otherwise issuable under the Plan be withheld by the Corporation in satisfaction of the withholding taxes incurred in connection with the exercise of an option or the vesting of a stock issuance under the Plan, then the number of shares of Common Stock available for issuance under the Plan shall be reduced by the gross number of shares for which the option is exercised or which vest under the stock issuance, and not by the net number of shares of Common Stock issued to the holder of such option or stock issuance. E. If any change is made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the maximum number and/or class of securities issuable under the Plan, (ii) the number and/or class of securities for which any one person may be granted stock options, separately exercisable stock appreciation rights and direct stock issuances under this Plan per calendar year, (iii) the number and/or class of securities for which grants are subsequently to be made under the Automatic Option Grant Program to new and continuing non-employee Board members, (iv) the number and/or class of securities and the exercise price per share in effect under each outstanding option under the Plan and (v) the number and/or class of securities and price per share in effect under each outstanding option incorporated into this Plan from the Predecessor Plan. Such adjustments to the outstanding options are to be effected in a manner which shall preclude the enlargement or dilution of rights and benefits under such options. The adjustments determined by the Plan Administrator shall be final, binding and conclusive. 5. 6 ARTICLE TWO DISCRETIONARY OPTION GRANT PROGRAM I. OPTION TERMS Each option shall be evidenced by one or more documents in the form approved by the Plan Administrator; provided, however, that each such document shall comply with the terms specified below. Each document evidencing an Incentive Option shall, in addition, be subject to the provisions of the Plan applicable to such options. A. EXERCISE PRICE. 1. The exercise price per share shall be fixed by the Plan Administrator but shall not be less than eighty-five percent (85%) of the Fair Market Value per share of Common Stock on the option grant date. 2. The exercise price shall become immediately due upon exercise of the option and shall, subject to the provisions of Section I of Article Six and the documents evidencing the option, be payable in one or more of the forms specified below: (i) cash or check made payable to the Corporation, (ii) shares of Common Stock held for the requisite period necessary to avoid a charge to the Corporation's earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date, or (iii) to the extent the option is exercised for vested shares, through a special sale and remittance procedure pursuant to which the Optionee shall concurrently provide irrevocable written instructions to (a) a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes required to be withheld by the Corporation by reason of such exercise and (b) the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale. Except to the extent such sale and remittance procedure is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. B. EXERCISE AND TERM OF OPTIONS. Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by 6. 7 the Plan Administrator and set forth in the documents evidencing the option. However, no option shall have a term in excess of ten (10) years measured from the option grant date. C. EFFECT OF TERMINATION OF SERVICE. 1. The following provisions shall govern the exercise of any options held by the Optionee at the time of cessation of Service or death: (i) Any option outstanding at the time of the Optionee's cessation of Service for any reason shall remain exercisable for such period of time thereafter as shall be determined by the Plan Administrator and set forth in the documents evidencing the option, but no such option shall be exercisable after the expiration of the option term. (ii) Any option exercisable in whole or in part by the Optionee at the time of death may be subsequently exercised by the personal representative of the Optionee's estate or by the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution. (iii) Should the Optionee's Service be terminated for Misconduct, then all outstanding options held by the Optionee shall terminate immediately and cease to be outstanding. (iv) During the applicable post-Service exercise period, the option may not be exercised in the aggregate for more than the number of vested shares for which the option is exercisable on the date of the Optionee's cessation of Service. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee's cessation of Service, terminate and cease to be outstanding to the extent the option is not otherwise at that time exercisable for vested shares. 2. The Plan Administrator shall have complete discretion, exercisable either at the time an option is granted or at any time while the option remains outstanding, to: (i) extend the period of time for which the option is to remain exercisable following the Optionee's cessation of Service from the limited exercise period otherwise in effect for that option to such greater period of time as the Plan Administrator shall deem appropriate, but in no event beyond the expiration of the option term, and/or 7. 8 (ii) permit the option to be exercised, during the applicable post-Service exercise period, not only with respect to the number of vested shares of Common Stock for which such option is exercisable at the time of the Optionee's cessation of Service but also with respect to one or more additional installments in which the Optionee would have vested had the Optionee continued in Service. D. STOCKHOLDER RIGHTS. The holder of an option shall have no stockholder rights with respect to the shares subject to the option until such person shall have exercised the option, paid the exercise price and become a holder of record of the purchased shares. E. REPURCHASE RIGHTS. The Plan Administrator shall have the discretion to grant options which are exercisable for unvested shares of Common Stock. Should the Optionee cease Service while holding such unvested shares, the Corporation shall have the right to repurchase, at the exercise price paid per share, any or all of those unvested shares. The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall be established by the Plan Administrator and set forth in the document evidencing such repurchase right. F. LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of the Optionee, Incentive Options shall be exercisable only by the Optionee and shall not be assignable or transferable other than by will or by the laws of descent and distribution following the Optionee's death. However, a Non-Statutory Option may, in connection with the Optionee's estate plan, be assigned in whole or in part during the Optionee's lifetime to one or more members of the Optionee's immediate family or to a trust established exclusively for one or more such family members. The assigned portion may only be exercised by the person or persons who acquire a proprietary interest in the option pursuant to the assignment. The terms applicable to the assigned portion shall be the same as those in effect for the option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate. II. INCENTIVE OPTIONS The terms specified below shall be applicable to all Incentive Options. Except as modified by the provisions of this Section II, all the provisions of Articles One, Two and Seven shall be applicable to Incentive Options. Options which are specifically designated as Non-Statutory Options when issued under the Plan shall not be subject to the terms of this Section II. A. ELIGIBILITY. Incentive Options may only be granted to Employees. 8. 9 B. EXERCISE PRICE. The exercise price per share shall not be less than one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. C. DOLLAR LIMITATION. The aggregate Fair Market Value of the shares of Common Stock (determined as of the respective date or dates of grant) for which one or more options granted to any Employee under the Plan (or any other option plan of the Corporation or any Parent or Subsidiary) may for the first time become exercisable as Incentive Options during any one calendar year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee holds two (2) or more such options which become exercisable for the first time in the same calendar year, the foregoing limitation on the exercisability of such options as Incentive Options shall be applied on the basis of the order in which such options are granted. D. 10% STOCKHOLDER. If any Employee to whom an Incentive Option is granted is a 10% Stockholder, then the exercise price per share shall not be less than one hundred ten percent (110%) of the Fair Market Value per share of Common Stock on the option grant date, and the option term shall not exceed five (5) years measured from the option grant date. III. CORPORATE TRANSACTION/CHANGE IN CONTROL A. In the event of any Corporate Transaction, each outstanding option shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become fully exercisable with respect to the total number of shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. However, an outstanding option shall not so accelerate if and to the extent: (i) such option is, in connection with the Corporate Transaction, either to be assumed by the successor corporation (or parent thereof) or to be replaced with a comparable option to purchase shares of the capital stock of the successor corporation (or parent thereof), (ii) such option is to be replaced with a cash incentive program of the successor corporation which preserves the spread existing on the unvested option shares at the time of the Corporate Transaction and provides for subsequent payout in accordance with the same vesting schedule applicable to those option shares or (iii) the acceleration of such option is subject to other limitations imposed by the Plan Administrator at the time of the option grant. The determination of option comparability under clause (i) above shall be made by the Plan Administrator, and its determination shall be final, binding and conclusive. B. All outstanding repurchase rights shall also terminate automatically, and the shares of Common Stock subject to those terminated rights shall immediately vest in full, in the event of any Corporate Transaction, except to the extent: (i) those repurchase rights are to be assigned to the successor corporation (or parent thereof) in connection with such 9. 10 Corporate Transaction or (ii) such accelerated vesting is precluded by other limitations imposed by the Plan Administrator at the time the repurchase right is issued. C. Immediately following the consummation of the Corporate Transaction, all outstanding options shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof). D. Each option which is assumed in connection with a Corporate Transaction shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to the Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction. Appropriate adjustments to reflect such Corporate Transaction shall also be made to (i) the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same, (ii) the maximum number and/or class of securities available for issuance over the remaining term of the Plan and (iii) the maximum number and/or class of securities for which any one person may be granted stock options, separately exercisable stock appreciation rights and direct stock issuances under the Plan per calendar year. E. The Plan Administrator shall have full power and authority to grant options under the Discretionary Option Grant Program which will automatically accelerate in the event the Optionee's Service subsequently terminates by reason of an Involuntary Termination within a designated period (not to exceed eighteen (18) months) following the effective date of any Corporate Transaction in which those options are assumed or replaced and do not otherwise accelerate. Any options so accelerated shall remain exercisable for fully-vested shares until the earlier of (i) the expiration of the option term or (ii) the expiration of the one (1)-year period measured from the effective date of the Involuntary Termination. In addition, the Plan Administrator may provide that one or more of the Corporation's outstanding repurchase rights with respect to shares held by the Optionee at the time of such Involuntary Termination shall immediately terminate, and the shares subject to those terminated repurchase rights shall accordingly vest in full. F. The Plan Administrator shall have full power and authority to grant options under the Discretionary Option Grant Program which will automatically accelerate in the event the Optionee's Service subsequently terminates by reason of an Involuntary Termination within a designated period (not to exceed eighteen (18) months) following the effective date of any Change in Control. Each option so accelerated shall remain exercisable for fully-vested shares until the earlier of (i) the expiration of the option term or (ii) the expiration of the one (1)-year period measured from the effective date of the Involuntary Termination. In addition, the Plan Administrator may provide that one or more of the Corporation's outstanding repurchase rights with respect to shares held by the Optionee at the time of such Involuntary Termination shall immediately terminate, and the shares subject to those terminated repurchase rights shall accordingly vest in full. 10. 11 G. The portion of any Incentive Option accelerated in connection with a Corporate Transaction or Change in Control shall remain exercisable as an Incentive Option only to the extent the applicable One Hundred Thousand Dollar limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the Federal tax laws. H. The outstanding options shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. IV. CANCELLATION AND REGRANT OF OPTIONS The Plan Administrator shall have the authority to effect, at any time and from time to time, with the consent of the affected option holders, the cancellation of any or all outstanding options under the Discretionary Option Grant Program (including outstanding options incorporated from the Predecessor Plan) and to grant in substitution new options covering the same or different number of shares of Common Stock but with an exercise price per share based on the Fair Market Value per share of Common Stock on the new grant date. V. STOCK APPRECIATION RIGHTS A. The Plan Administrator shall have full power and authority to grant to selected Optionees tandem stock appreciation rights and/or limited stock appreciation rights. B. The following terms shall govern the grant and exercise of tandem stock appreciation rights: (i) One or more Optionees may be granted the right, exercisable upon such terms as the Plan Administrator may establish, to elect between the exercise of the underlying option for shares of Common Stock and the surrender of that option in exchange for a distribution from the Corporation in an amount equal to the excess of (a) the Fair Market Value (on the option surrender date) of the number of shares in which the Optionee is at the time vested under the surrendered option (or surrendered portion thereof) over (b) the aggregate exercise price payable for such shares. (ii) No such option surrender shall be effective unless it is approved by the Plan Administrator, either at the time of the actual option surrender or at any earlier time. If the surrender is so approved, then the distribution to which the Optionee shall be entitled may be made in shares of Common Stock valued at Fair Market Value on the option 11. 12 surrender date, in cash, or partly in shares and partly in cash, as the Plan Administrator shall in its sole discretion deem appropriate. (iii) If the surrender of an option is not approved by the Plan Administrator, then the Optionee shall retain whatever rights the Optionee had under the surrendered option (or surrendered portion thereof) on the option surrender date and may exercise such rights at any time prior to the later of (a) five (5) business days after the receipt of the rejection notice or (b) the last day on which the option is otherwise exercisable in accordance with the terms of the documents evidencing such option, but in no event may such rights be exercised more than ten (10) years after the option grant date. C. The following terms shall govern the grant and exercise of limited stock appreciation rights: (i) One or more Section 16 Insiders may be granted limited stock appreciation rights with respect to their outstanding options. (ii) Upon the occurrence of a Hostile Take-Over, each individual holding one or more options with such a limited stock appreciation right shall have the unconditional right (exercisable for a thirty (30)-day period following such Hostile Take-Over) to surrender each such option to the Corporation, to the extent the option is at the time exercisable for vested shares of Common Stock. In return for the surrendered option, the Optionee shall receive a cash distribution from the Corporation in an amount equal to the excess of (A) the Take-Over Price of the shares of Common Stock which are at the time vested under each surrendered option (or surrendered portion thereof) over (B) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following the option surrender date. (iii) Neither the approval of the Plan Administrator nor the consent of the Board shall be required in connection with such option surrender and cash distribution. (iv) The balance of the option (if any) shall remain outstanding and exercisable in accordance with the documents evidencing such option. 12. 13 ARTICLE THREE SALARY INVESTMENT OPTION GRANT PROGRAM I. OPTION GRANTS The Primary Committee shall have the sole and exclusive authority to determine the calendar year or years (if any) for which the Salary Investment Option Grant Program is to be in effect and to select the Section 16 Insiders and other highly compensated Employees eligible to participate in the Salary Investment Option Grant Program for those calendar year or years. Each selected individual who elects to participate in the Salary Investment Option Grant Program must, prior to the start of each calendar year of participation, file with the Plan Administrator (or its designate) an irrevocable authorization directing the Corporation to reduce his or her base salary for that calendar year by an amount not less than Ten Thousand Dollars ($10,000.00) nor more than Fifty Thousand Dollars ($50,000.00). The Primary Committee shall have complete discretion to determine whether to approve the filed authorization in whole or in part. To the extent the Primary Committee approves the authorization, the individual who filed that authorization shall be granted an option under the Salary Investment Grant Program on or before the last trading day in January for the calendar year for which the salary reduction is to be in effect. All grants under the Salary Investment Option Grant Program shall be at the sole discretion of the Primary Committee. II. OPTION TERMS Each option shall be a Non-Statutory Option evidenced by one or more documents in the form approved by the Plan Administrator; provided, however, that each such document shall comply with the terms specified below. A. EXERCISE PRICE. 1. The exercise price per share shall be thirty-three and one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock on the option grant date. 2. The exercise price shall become immediately due upon exercise of the option and shall be payable in one or more of the alternative forms authorized under the Discretionary Option Grant Program. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. B. NUMBER OF OPTION SHARES. The number of shares of Common Stock subject to the option shall be determined pursuant to the following formula (rounded down to the nearest whole number): 13. 14 X = A / (B x 66-2/3%), where X is the number of option shares, A is the dollar amount of the approved reduction in the Optionee's base salary for the calendar year, and B is the Fair Market Value per share of Common Stock on the option grant date. C. EXERCISE AND TERM OF OPTIONS. The option shall become exercisable in a series of twelve (12) successive equal monthly installments upon the Optionee's completion of each calendar month of Service in the calendar year for which the salary reduction is in effect. Each option shall have a maximum term of ten (10) years measured from the option grant date. D. EFFECT OF TERMINATION OF SERVICE. Should the Optionee cease Service for any reason while holding one or more options under this Article Three, then each such option shall remain exercisable, for any or all of the shares for which the option is exercisable at the time of such cessation of Service, until the earlier of (i) the expiration of the ten (10)-year option term or (ii) the expiration of the two (2)-year period measured from the date of such cessation of Service. Should the Optionee die while holding one or more options under this Article Three, then each such option may be exercised, for any or all of the shares for which the option is exercisable at the time of the Optionee's cessation of Service (less any shares subsequently purchased by Optionee prior to death), by the personal representative of the Optionee's estate or by the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution. Such right of exercise shall lapse, and the option shall terminate, upon the earlier of (i) the expiration of the ten (10)-year option term or (ii) the two (2)-year period measured from the date of the Optionee's cessation of Service. However, the option shall, immediately upon the Optionee's cessation of Service for any reason, terminate and cease to remain outstanding with respect to any and all shares of Common Stock for which the option is not otherwise at that time exercisable. III. CORPORATE TRANSACTION/CHANGE IN CONTROL A. In the event of any Corporate Transaction while the Optionee remains in Service, each outstanding option held by such Optionee under this Salary Investment Option Grant Program shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become fully exercisable with respect to the total number of shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. Each such outstanding option shall be assumed by the successor corporation (or parent thereof) in the Corporate Transaction and shall remain exercisable 14. 15 for the fully-vested shares until the earlier of (i) the expiration of the ten (10)-year option term or (ii) the expiration of the two (2)-year period measured from the date of the Optionee's cessation of Service. B. In the event of a Change in Control while the Optionee remains in Service, each outstanding option held by such Optionee under this Salary Investment Option Grant Program shall automatically accelerate so that each such option shall immediately become fully exercisable with respect to the total number of shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. The option shall remain so exercisable until the earlier or (i) the expiration of the ten (10)-year option term or (ii) the expiration of the two (2)- year period measured from the date of the Optionee's cessation of Service. C. Upon the occurrence of a Hostile Take-Over, the Optionee shall have a thirty (30)-day period in which to surrender to the Corporation each of his or her outstanding option grants. The Optionee shall in return be entitled to a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over Price of the shares of Common Stock at the time subject to each surrendered option (whether or not the Optionee is otherwise at the time vested in those shares) over (ii) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following the surrender of the option to the Corporation. No approval or consent of the Board or any Plan Administrator shall be required in connection with such option surrender and cash distribution. D. The grant of options under the Salary Investment Option Grant Program shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. III. REMAINING TERMS The remaining terms of each option granted under the Salary Investment Option Grant Program shall be the same as the terms in effect for option grants made under the Discretionary Option Grant Program. 15. 16 ARTICLE FOUR STOCK ISSUANCE PROGRAM I. STOCK ISSUANCE TERMS Shares of Common Stock may be issued under the Stock Issuance Program through direct and immediate issuances without any intervening option grants. Each such stock issuance shall be evidenced by a Stock Issuance Agreement which complies with the terms specified below. A. PURCHASE PRICE. 1. The purchase price per share shall be fixed by the Plan Administrator, but shall not be less than one hundred percent (100%) of the Fair Market Value per share of Common Stock on the issuance date. 2. Subject to the provisions of Section I of Article Seven, shares of Common Stock may be issued under the Stock Issuance Program for any of the following items of consideration which the Plan Administrator may deem appropriate in each individual instance: (i) cash or check made payable to the Corporation, or (ii) past services rendered to the Corporation (or any Parent or Subsidiary). B. VESTING PROVISIONS. 1. Shares of Common Stock issued under the Stock Issuance Program may, in the discretion of the Plan Administrator, be fully and immediately vested upon issuance or may vest in one or more installments over the Participant's period of Service or upon attainment of specified performance objectives. The elements of the vesting schedule applicable to any unvested shares of Common Stock issued under the Stock Issuance Program, namely: (i) the Service period to be completed by the Participant or the performance objectives to be attained, (ii) the number of installments in which the shares are to vest, 16. 17 (iii) the interval or intervals (if any) which are to lapse between installments, and (iv) the effect which death, Permanent Disability or other event designated by the Plan Administrator is to have upon the vesting schedule, shall be determined by the Plan Administrator and incorporated into the Stock Issuance Agreement. 2. Any new, substituted or additional securities or other property (including money paid other than as a regular cash dividend) which the Participant may have the right to receive with respect to the Participant's unvested shares of Common Stock by reason of any stock dividend, stock split, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration shall be issued subject to (i) the same vesting requirements applicable to the Participant's unvested shares of Common Stock and (ii) such escrow arrangements as the Plan Administrator shall deem appropriate. 3. The Participant shall have full stockholder rights with respect to any shares of Common Stock issued to the Participant under the Stock Issuance Program, whether or not the Participant's interest in those shares is vested. Accordingly, the Participant shall have the right to vote such shares and to receive any regular cash dividends paid on such shares. 4. Should the Participant cease to remain in Service while holding one or more unvested shares of Common Stock issued under the Stock Issuance Program or should the performance objectives not be attained with respect to one or more such unvested shares of Common Stock, then those shares shall be immediately surrendered to the Corporation for cancellation, and the Participant shall have no further stockholder rights with respect to those shares. To the extent the surrendered shares were previously issued to the Participant for consideration paid in cash or cash equivalent (including the Participant's purchase-money indebtedness), the Corporation shall repay to the Participant the cash consideration paid for the surrendered shares and shall cancel the unpaid principal balance of any outstanding purchase-money note of the Participant attributable to the surrendered shares. 5. The Plan Administrator may in its discretion waive the surrender and cancellation of one or more unvested shares of Common Stock which would otherwise occur upon the cessation of the Participant's Service or the non-attainment of the performance objectives applicable to those shares. Such waiver shall result in the immediate vesting of the Participant's interest in the shares as to which the waiver applies. Such waiver may be effected at any time, whether before or after the Participant's cessation of Service or the attainment or non-attainment of the applicable performance objectives. 17. 18 II. CORPORATE TRANSACTION/CHANGE IN CONTROL A. All of the Corporation's outstanding repurchase/cancellation rights under the Stock Issuance Program shall terminate automatically, and all the shares of Common Stock subject to those terminated rights shall immediately vest in full, in the event of any Corporate Transaction, except to the extent (i) those repurchase/cancellation rights are to be assigned to the successor corporation (or parent thereof) in connection with such Corporate Transaction or (ii) such accelerated vesting is precluded by other limitations imposed in the Stock Issuance Agreement. B. The Plan Administrator shall have the discretionary authority, exercisable either at the time the unvested shares are issued or any time while the Corporation's repurchase/cancellation rights remain outstanding under the Stock Issuance Program, to provide that those rights shall automatically terminate in whole or in part, and the shares of Common Stock subject to those terminated rights shall immediately vest, in the event the Participant's Service should subsequently terminate by reason of an Involuntary Termination within a designated period (not to exceed eighteen (18) months) following the effective date of any Corporate Transaction in which those repurchase/cancellation rights are assigned to the successor corporation (or parent thereof). C. The Plan Administrator shall have the discretionary authority, exercisable either at the time the unvested shares are issued or any time while the Corporation's repurchase/cancellation rights remain outstanding under the Stock Issuance Program, to provide that those rights shall automatically terminate in whole or in part, and the shares of Common Stock subject to those terminated rights shall immediately vest, in the event the Participant's Service should subsequently terminate by reason of an Involuntary Termination within a designated period (not to exceed eighteen (18) months) following the effective date of any Change in Control. III. SHARE ESCROW/LEGENDS Unvested shares may, in the Plan Administrator's discretion, be held in escrow by the Corporation until the Participant's interest in such shares vests or may be issued directly to the Participant with restrictive legends on the certificates evidencing those unvested shares. 18. 19 ARTICLE FIVE AUTOMATIC OPTION GRANT PROGRAM I. OPTION TERMS A. GRANT DATES. Option grants shall be made on the dates specified below: 1. Each individual serving as a non-employee Board member on the Underwriting Date shall automatically be granted at that time a Non-Statutory Option to purchase 10,000 shares of Common Stock, provided that individual has not previously been in the employ of the Corporation or any Parent or Subsidiary and has not previously received a stock option grant from the Corporation. 2. Each individual who is first elected or appointed as a non- employee Board member at any time after the Underwriting Date shall automatically be granted, on the date of such initial election or appointment, a Non-Statutory Option to purchase 10,000 shares of Common Stock, provided that individual has not previously been in the employ of the Corporation or any Parent or Subsidiary. 3. On the date of each Annual Stockholders Meeting held after the Underwriting Date, each individual who is to continue to serve as an Eligible Director, whether or not that individual is standing for re-election to the Board at that particular Annual Meeting, shall automatically be granted a Non-Statutory Option to purchase 1,500 shares of Common Stock, provided such individual has served as a non-employee Board member for at least six (6) months. There shall be no limit on the number of such 1,500- share option grants any one Eligible Director may receive over his or her period of Board service, and non-employee Board members who have previously been in the employ of the Corporation (or any Parent or Subsidiary) or who have otherwise received a stock option grant from the Corporation prior to the Underwriting Date shall be eligible to receive one or more such annual option grants over their period of continued Board service. B. EXERCISE PRICE. 1. The exercise price per share shall be equal to one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. 2.

OPTION TERM. Each option shall have a term of ten (10) years measured from the option grant date. D. EXERCISE AND VESTING OF OPTIONS. Each option shall be immediately exercisable for any or all of the option shares. However, any shares purchased under the option shall be subject to repurchase by the Corporation, at the exercise price paid per share, upon the Optionee's cessation of Board service prior to vesting in those shares. Each initial 10,000-share grant shall vest, and the Corporation's repurchase right shall lapse, in a series of four (4) successive equal annual installments upon the Optionee's completion of each year of Board service over the four (4)-year period measured from the option grant date. Each annual 1,500-share grant shall vest, and the Corporation's repurchase right shall lapse, upon the Optionee's completion of one (1) year of Board service measured from the automatic grant date. E. TERMINATION OF BOARD SERVICE. The following provisions shall govern the exercise of any options held by the Optionee at the time the Optionee ceases to serve as a Board member: (i) The Optionee (or, in the event of Optionee's death, the personal representative of the Optionee's estate or the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution) shall have a twelve (12)-month period following the date of such cessation of Board service in which to exercise each such option. (ii) During the twelve (12)-month exercise period, the option may not be exercised in the aggregate for more than the number of vested shares of Common Stock for which the option is exercisable at the time of the Optionee's cessation of Board service. (iii) Should the Optionee cease to serve as a Board member by reason of death or Permanent Disability, then all shares at the time subject to the option shall immediately vest so that such option may, during the twelve (12)-month exercise period following such cessation of Board service, be exercised for all or any portion of those shares as fully-vested shares of Common Stock. (iv) In no event shall the option remain exercisable after the expiration of the option term. Upon the expiration of the twelve (12)-month exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee's cessation of Board service for any reason other than death or Permanent Disability, terminate and cease to be 20. 21 outstanding to the extent the option is not otherwise at that time exercisable for vested shares. II. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE- OVER A. In the event of any Corporate Transaction, the shares of Common Stock at the time subject to each outstanding option but not otherwise vested shall automatically vest in full so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become fully exercisable for all of the shares of Common Stock at the time subject to such option and may be exercised for all or any portion of those shares as fully-vested shares of Common Stock. Immediately following the consummation of the Corporate Transaction, each automatic option grant shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof). B. In connection with any Change in Control, the shares of Common Stock at the time subject to each outstanding option but not otherwise vested shall automatically vest in full so that each such option shall, immediately prior to the effective date of the Change in Control, become fully exercisable for all of the shares of Common Stock at the time subject to such option and may be exercised for all or any portion of those shares as fully-vested shares of Common Stock. Each such option shall remain exercisable for such fully-vested option shares until the expiration or sooner termination of the option term or the surrender of the option in connection with a Hostile Take-Over. C. Upon the occurrence of a Hostile Take-Over, the Optionee shall have a thirty (30)-day period in which to surrender to the Corporation each of his or her outstanding automatic option grants. The Optionee shall in return be entitled to a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over Price of the shares of Common Stock at the time subject to each surrendered option (whether or not the Optionee is otherwise at the time vested in those shares) over (ii) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following the surrender of the option to the Corporation. No approval or consent of the Board or any Plan Administrator shall be required in connection with such option surrender and cash distribution. D. Each option which is assumed in connection with a Corporate Transaction shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to the Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction. Appropriate adjustments shall also be made to the exercise price payable per share under each outstanding option, provided the aggregate exercise price payable for such securities shall remain the same. 21. 22 E. The grant of options under the Automatic Option Grant Program shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. III. REMAINING TERMS The remaining terms of each option granted under the Automatic Option Grant Program shall be the same as the terms in effect for option grants made under the Discretionary Option Grant Program. 22. 23 ARTICLE SIX DIRECTOR FEE OPTION GRANT PROGRAM I.

Such election must be filed with the Corporation's Chief Financial Officer prior to the first day of the calendar year for which the annual retainer fee which is the subject of that election is otherwise payable. Each non-employee Board member who files such a timely election shall automatically be granted an option under this Director Fee Option Grant Program on the first trading day in January in the calendar year for which the annual retainer fee which is the subject of that election would otherwise be payable. II. OPTION TERMS Each option shall be a Non-Statutory Option governed by the terms and conditions specified below. A. EXERCISE PRICE. 1. The exercise price per share shall be thirty-three and one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock on the option grant date. 2. The exercise price shall become immediately due upon exercise of the option and shall be payable in one or more of the alternative forms authorized under the Discretionary Option Grant Program. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. B. NUMBER OF OPTION SHARES. The number of shares of Common Stock subject to the option shall be determined pursuant to the following formula (rounded down to the nearest whole number): X = A / (B x 66-2/3%), where X is the number of option shares, A is the portion of the annual retainer fee subject to the non-employee Board member's election, and 23. 24 B is the Fair Market Value per share of Common Stock on the option grant date. C. EXERCISE AND TERM OF OPTIONS. The option shall become exercisable for fifty percent (50%) of the option shares upon the Optionee's completion of six (6) months of Board service in the calendar year for which his or her election under this Director Fee Option Grant Program is in effect, and the balance of the option shares shall become exercisable in a series of six (6) successive equal monthly installments upon the Optionee's completion of each additional month of Board service during that calendar year. Each option shall have a maximum term of ten (10) years measured from the option grant date. D. TERMINATION OF BOARD SERVICE. Should the Optionee cease Board service for any reason (other than death or Permanent Disability) while holding one or more options under this Director Fee Option Grant Program, then each such option shall remain exercisable, for any or all of the shares for which the option is exercisable at the time of such cessation of Board service, until the earlier of (i) the expiration of the ten (10)-year option term or (ii) the expiration of the two (2)-year period measured from the date of such cessation of Board service. However, each option held by the Optionee under this Director Fee Option Grant Program at the time of his or her cessation of Board service shall immediately terminate and cease to remain outstanding with respect to any and all shares of Common Stock for which the option is not otherwise at that time exercisable. E. DEATH OR PERMANENT DISABILITY. Should the Optionee's service as a Board member cease by reason of death or Permanent Disability, then each option held by such Optionee under this Director Fee Option Grant Program shall immediately become exercisable for all the shares of Common Stock at the time subject to that option, and the option may be exercised for any or all of those shares as fully-vested shares until the earlier of (i) the expiration of the ten (10)-year option term or (ii) the expiration of the two (2)-year period measured from the date of such cessation of Board service. Should the Optionee die after cessation of Board service but while holding one or more options under this Director Fee Option Grant Program, then each such option may be exercised, for any or all of the shares for which the option is exercisable at the time of the Optionee's cessation of Board service (less any shares subsequently purchased by Optionee prior to death), by the personal representative of the Optionee's estate or by the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution. Such right of exercise shall lapse, and the option shall terminate, upon the earlier of (i) the expiration of the ten (10)-year option term or (ii) the two (2)-year period measured from the date of the Optionee's cessation of Board service. 24. 25 III. CORPORATE TRANSACTION/CHANGE IN CONTROL A. In the event of any Corporate Transaction while the Optionee remains a Board member, each outstanding option held by such Optionee under this Director Fee Option Grant Program shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become fully exercisable with respect to the total number of shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. Each such outstanding option shall be assumed by the successor corporation (or parent thereof) in the Corporate Transaction and shall remain exercisable for the fully-vested shares until the earlier of (i) the expiration of the ten (10)-year option term or (ii) the expiration of the two (2)-year period measured from the date of the Optionee's cessation of Board service. B. In the event of a Change in Control while the Optionee remains in Service, each outstanding option held by such Optionee under this Director Fee Option Grant Program shall automatically accelerate so that each such option shall immediately become fully exercisable with respect to the total number of shares of Common Stock at the time subject to such option and may be exercised for any or all of those shares as fully-vested shares of Common Stock. The option shall remain so exercisable until the earlier or (i) the expiration of the ten (10)-year option term or (ii) the expiration of the two (2)-year period measured from the date of the Optionee's cessation of Service. C. Upon the occurrence of a Hostile Take-Over, the Optionee shall have a thirty (30)-day period in which to surrender to the Corporation each of his or her outstanding option grants. The Optionee shall in return be entitled to a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over Price of the shares of Common Stock at the time subject to each surrendered option (whether or not the Optionee is otherwise at the time vested in those shares) over (ii) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following the surrender of the option to the Corporation. No approval or consent of the Board or any Plan Administrator shall be required in connection with such option surrender and cash distribution. D. The grant of options under the Director Fee Option Grant Program shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. IV. REMAINING TERMS The remaining terms of each option granted under this Director Fee Option Grant Program shall be the same as the terms in effect for option grants made under the Discretionary Option Grant Program. 25. 26 ARTICLE SEVEN MISCELLANEOUS I. FINANCING The Plan Administrator may permit any Optionee or Participant to pay the option exercise price under the Discretionary Option Grant Program or the purchase price of shares issued under the Stock Issuance Program by delivering a full-recourse, interest bearing promissory note payable in one or more installments. The terms of any such promissory note (including the interest rate and the terms of repayment) shall be established by the Plan Administrator in its sole discretion. In no event may the maximum credit available to the Optionee or Participant exceed the sum of (i) the aggregate option exercise price or purchase price payable for the purchased shares plus (ii) any Federal, state and local income and employment tax liability incurred by the Optionee or the Participant in connection with the option exercise or share purchase. II. TAX WITHHOLDING A. The Corporation's obligation to deliver shares of Common Stock upon the exercise of options or the issuance or vesting of such shares under the Plan shall be subject to the satisfaction of all applicable Federal, state and local income and employment tax withholding requirements. B. The Plan Administrator may, in its discretion, provide any or all holders of Non-Statutory Options or unvested shares of Common Stock under the Plan (other than the options granted or the shares issued under the Automatic Option Grant or Director Fee Option Grant Program) with the right to use shares of Common Stock in satisfaction of all or part of the Taxes incurred by such holders in connection with the exercise of their options or the vesting of their shares. Such right may be provided to any such holder in either or both of the following formats: Stock Withholding: The election to have the Corporation withhold, from the shares of Common Stock otherwise issuable upon the exercise of such Non-Statutory Option or the vesting of such shares, a portion of those shares with an aggregate Fair Market Value equal to the percentage of the Taxes (not to exceed one hundred percent (100%)) designated by the holder. Stock Delivery: The election to deliver to the Corporation, at the time the Non-Statutory Option is exercised or the shares vest, one or more shares of Common Stock previously acquired by such holder (other than in connection with the option exercise or share vesting triggering the Taxes) with an aggregate Fair Market Value equal to the percentage of the Taxes (not to exceed one hundred percent (100%)) designated by the holder. 26. 27 III.

Options may be granted under the Discretionary Option Grant or Automatic Option Grant Program at any time on or after the Plan Effective Date. However, no options granted under the Plan may be exercised, and no shares shall be issued under the Plan, until the Plan is approved by the Corporation's stockholders. If such stockholder approval is not obtained within twelve (12) months after the Plan Effective Date, then all options previously granted under this Plan shall terminate and cease to be outstanding, and no further options shall be granted and no shares shall be issued under the Plan. B. The Plan shall serve as the successor to the Predecessor Plan, and no further option grants or direct stock issuances shall be made under the Predecessor Plan after the Section 12 Registration Date. All options outstanding under the Predecessor Plan on the Section 12 Registration Date shall be incorporated into the Plan at that time and shall be treated as outstanding options under the Plan. However, each outstanding option so incorporated shall continue to be governed solely by the terms of the documents evidencing such option, and no provision of the Plan shall be deemed to affect or otherwise modify the rights or obligations of the holders of such incorporated options with respect to their acquisition of shares of Common Stock. C. One or more provisions of the Plan, including (without limitation) the option/vesting acceleration provisions of Article Two relating to Corporate Transactions and Changes in Control, may, in the Plan Administrator's discretion, be extended to one or more options incorporated from the Predecessor Plan which do not otherwise contain such provisions. D. The Plan shall terminate upon the earliest of (i) July 16, 2006, (ii) the date on which all shares available for issuance under the Plan shall have been issued as fully-vested shares or (iii) the termination of all outstanding options in connection with a Corporate Transaction. Upon such plan termination, all outstanding option grants and unvested stock issuances shall thereafter continue to have force and effect in accordance with the provisions of the documents evidencing such grants or issuances. IV. AMENDMENT OF THE PLAN A. The Board shall have complete and exclusive power and authority to amend or modify the Plan in any or all respects. However, no such amendment or modification shall adversely affect the rights and obligations with respect to stock options or unvested stock issuances at the time outstanding under the Plan unless the Optionee or the Participant consents to such amendment or modification. In addition, certain amendments may require stockholder approval pursuant to applicable laws or regulations. 27. 28 B. Options to purchase shares of Common Stock may be granted under the Discretionary Option Grant and Salary Investment Option Grant Programs and shares of Common Stock may be issued under the Stock Issuance Program that are in each instance in excess of the number of shares then available for issuance under the Plan, provided any excess shares actually issued under those programs shall be held in escrow until there is obtained stockholder approval of an amendment sufficiently increasing the number of shares of Common Stock available for issuance under the Plan. If such stockholder approval is not obtained within twelve (12) months after the date the first such excess issuances are made, then (i) any unexercised options granted on the basis of such excess shares shall terminate and cease to be outstanding and (ii) the Corporation shall promptly refund to the Optionees and the Participants the exercise or purchase price paid for any excess shares issued under the Plan and held in escrow, together with interest (at the applicable Short Term Federal Rate) for the period the shares were held in escrow, and such shares shall thereupon be automatically cancelled and cease to be outstanding. V. USE OF PROCEEDS Any cash proceeds received by the Corporation from the sale of shares of Common Stock under the Plan shall be used for general corporate purposes. VI. REGULATORY APPROVALS A. The implementation of the Plan, the granting of any stock option under the Plan and the issuance of any shares of Common Stock (i) upon the exercise of any granted option or (ii) under the Stock Issuance Program shall be subject to the Corporation's procurement of all approvals and permits required by regulatory authorities having jurisdiction over the Plan, the stock options granted under it and the shares of Common Stock issued pursuant to it. B. No shares of Common Stock or other assets shall be issued or delivered under the Plan unless and until there shall have been compliance with all applicable requirements of Federal and state securities laws, including the filing and effectiveness of the Form S-8 registration statement for the shares of Common Stock issuable under the Plan, and all applicable listing requirements of any stock exchange (or the Nasdaq National Market, if applicable) on which Common Stock is then listed for trading. VII. NO EMPLOYMENT/SERVICE RIGHTS Nothing in the Plan shall confer upon the Optionee or the Participant 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 Corporation (or any Parent or Subsidiary employing or retaining such person) or of the Optionee or the Participant, which rights are hereby expressly reserved by each, to terminate such person's Service at any time for any reason, with or without cause. 28. 29 APPENDIX The following definitions shall be in effect under the Plan: A.

The Board has adopted the Plan for the purpose of retaining the services of selected Employees, non-employee members of the Board or of the board of directors of any Parent or Subsidiary and consultants and other independent advisors who provide services to the Corporation (or any Parent or Subsidiary). B. Optionee is to render valuable services to the Corporation (or a Parent or Subsidiary), and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Corporation's grant of an option to Optionee. C. All capitalized terms in this Agreement shall have the meaning assigned to them in the attached Appendix. NOW, THEREFORE, it is hereby agreed as follows: 1. GRANT OF OPTION. The Corporation hereby grants to Optionee, as of the Grant Date, an option to purchase up to the number of Option Shares specified in the Grant Notice. The Option Shares shall be purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price. 2. OPTION TERM. This option shall have a maximum term of ten (10) years measured from the Grant Date and shall accordingly expire at the close of business on the Expiration Date, unless sooner terminated in accordance with Paragraph 5 or 6. 3. LIMITED TRANSFERABILITY. This option shall be neither transferable nor assignable by Optionee other than by will or by the laws of descent and distribution following Optionee's death and may be exercised, during Optionee's lifetime, only by Optionee. However, if this option is designated a Non-Statutory Option in the Grant Notice, then this option may, in connection with the Optionee's estate plan, be assigned in whole or in part during Optionee's lifetime to one or more members of the Optionee's immediate family or to a trust established for the exclusive benefit of one or more such family members. The assigned portion shall be exercisable only by the person or persons who acquire a proprietary interest in the option pursuant to such assignment. The terms applicable to the assigned portion shall be the same as those in effect for this option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate. 4. DATES OF EXERCISE. This option shall become exercisable for the Option Shares in one or more installments as specified in the Grant Notice. As the option becomes 2 exercisable for such installments, those installments shall accumulate and the option shall remain exercisable for the accumulated installments until the Expiration Date or sooner termination of the option term under Paragraph 5 or 6. 5. CESSATION OF SERVICE. The option term specified in Paragraph 2 shall terminate (and this option shall cease to be outstanding) prior to the Expiration Date should any of the following provisions become applicable: (i) Should Optionee cease to remain in Service for any reason (other than death, Permanent Disability or Misconduct) while this option is outstanding, then Optionee shall have a period of three (3) months (commencing with the date of such cessation of Service) during which to exercise this option, but in no event shall this option be exercisable at any time after the Expiration Date. (ii) If Optionee dies while this option is outstanding, then the personal representative of Optionee's estate or the person or persons to whom the option is transferred pursuant to Optionee's will or in accordance with the laws of descent and distribution shall have the right to exercise this option. Such right shall lapse, and this option shall cease to be outstanding, upon the earlier of (A) the expiration of the twelve (12)- month period measured from the date of Optionee's death or (B) the Expiration Date. (iii) Should Optionee cease Service by reason of Permanent Disability while this option is outstanding, then Optionee shall have a period of twelve (12) months (commencing with the date of such cessation of Service) during which to exercise this option. In no event shall this option be exercisable at any time after the Expiration Date. (iv) During the limited period of post-Service exercisability, this option may not be exercised in the aggregate for more than the number of vested Option Shares for which the option is exercisable at the time of Optionee's cessation of Service. Upon the expiration of such limited exercise period or (if earlier) upon the Expiration Date, this option shall terminate and cease to be outstanding for any vested Option Shares for which the option has not been exercised. However, this option shall, immediately upon Optionee's cessation of Service for any reason, terminate and cease to be outstanding with respect to any Option Shares in which Optionee is not otherwise at that time vested or for which this option is not otherwise at that time exercisable. 2. 3 (v) Should Optionee's Service be terminated for Misconduct, then this option shall terminate immediately and cease to remain outstanding. 6. SPECIAL ACCELERATION OF OPTION. (a) This option, to the extent outstanding at the time of a Corporate Transaction but not otherwise fully exercisable, shall automatically accelerate so that this option shall, immediately prior to the effective date of the Corporate Transaction, become exercisable for all of the Option Shares at the time subject to this option and may be exercised for any or all of those Option Shares as fully-vested shares of Common Stock. No such acceleration of this option, however, shall occur if and to the extent: (i) this option is, in connection with the Corporate Transaction, either to be assumed by the successor corporation (or parent thereof) or to be replaced with a comparable option to purchase shares of the capital stock of the successor corporation (or parent thereof) or (ii) this option is to be replaced with a cash incentive program of the successor corporation which preserves the spread existing on the unvested Option Shares at the time of the Corporate Transaction (the excess of the Fair Market Value of those Option Shares over the aggregate Exercise Price payable for such shares) and provides for subsequent pay-out in accordance with the same option exercise/vesting schedule set forth in the Grant Notice. The determination of option comparability under clause (i) shall be made by the Plan Administrator, and such determination shall be final, binding and conclusive. (b) Immediately following the Corporate Transaction, this option shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) in connection with the Corporate Transaction. (c) If this option is assumed in connection with a Corporate Transaction, then this option shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. (d) This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 7. ADJUSTMENT IN OPTION SHARES. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be 3. 4 made to (i) the total number and/or class of securities subject to this option and (ii) the Exercise Price in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder. 8. STOCKHOLDER RIGHTS. The holder of this option shall not have any stockholder rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become a holder of record of the purchased shares. 9. MANNER OF EXERCISING OPTION.

(ii) Pay the aggregate Exercise Price for the purchased shares in one or more of the following forms: (A) cash or check made payable to the Corporation; (B) a promissory note payable to the Corporation, but only to the extent authorized by the Plan Administrator in accordance with Paragraph 13; (C) shares of Common Stock held by Optionee (or any other person or persons exercising the option) for the requisite period necessary to avoid a charge to the Corporation's earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date; or (D) to the extent the option is exercised for vested Option Shares, through a special sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising the option) shall concurrently provide irrevocable written instructions (I) to a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes required to be withheld by the Corporation by reason of such exercise and (II) to the Corporation to deliver the certificates for the purchased 4. 5 shares directly to such brokerage firm in order to complete the sale transaction. Except to the extent the sale and remittance procedure is utilized in connection with the option exercise, payment of the Exercise Price must accompany the Notice of Exercise delivered to the Corporation in connection with the option exercise. (iii) Furnish to the Corporation appropriate documentation that the person or persons exercising the option (if other than Optionee) have the right to exercise this option.

(b) The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the Corporation to be necessary to the lawful issuance and sale of any Common Stock pursuant to this option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. The Corporation, however, shall use its best efforts to obtain all such approvals. 11. SUCCESSORS AND ASSIGNS. Except to the extent otherwise provided in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Optionee, Optionee's assigns and the legal representatives, heirs and legatees of Optionee's estate. 5. 6 12.

CONSTRUCTION. This Agreement and the option evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan.

GOVERNING LAW. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of California without resort to that State's conflict-of-laws rules. 16. EXCESS SHARES. If the Option Shares covered by this Agreement exceed, as of the Grant Date, the number of shares of Common Stock which may without stockholder approval be issued under the Plan, then this option shall be void with respect to those excess shares, unless stockholder approval of an amendment sufficiently increasing the number of shares of Common Stock issuable under the Plan is obtained in accordance with the provisions of the Plan. 17. ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION. In the event this option is designated an Incentive Option in the Grant Notice, the following terms and conditions shall also apply to the grant: - This option shall cease to qualify for favorable tax treatment as an Incentive Option if (and to the extent) this option is exercised for one or more Option Shares: (A) more than three (3) months after the date Optionee ceases to be an Employee for any reason other than death or Permanent Disability or (B) more than twelve (12) months after the date Optionee ceases to be an Employee by reason of Permanent Disability. 6. 7 - No installment under this option shall qualify for favorable tax treatment as an Incentive Option if (and to the extent) the aggregate Fair Market Value (determined at the Grant Date) of the Common Stock for which such installment first becomes exercisable hereunder would, when added to the aggregate value (determined as of the respective date or dates of grant) of the Common Stock or other securities for which this option or any other Incentive Options granted to Optionee prior to the Grant Date (whether under the Plan or any other option plan of the Corporation or any Parent or Subsidiary) first become exercisable during the same calendar year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate. Should such One Hundred Thousand Dollar ($100,000) limitation be exceeded in any calendar year, this option shall nevertheless become exercisable for the excess shares in such calendar year as a Non-Statutory Option. - Should the exercisability of this option be accelerated upon a Corporate Transaction, then this option shall qualify for favorable tax treatment as an Incentive Option only to the extent the aggregate Fair Market Value (determined at the Grant Date) of the Common Stock for which this option first becomes exercisable in the calendar year in which the Corporate Transaction occurs does not, when added to the aggregate value (determined as of the respective date or dates of grant) of the Common Stock or other securities for which this option or one or more other Incentive Options granted to Optionee prior to the Grant Date (whether under the Plan or any other option plan of the Corporation or any Parent or Subsidiary) first become exercisable during the same calendar year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate. Should the applicable One Hundred Thousand Dollar ($100,000) limitation be exceeded in the calendar year of such Corporate Transaction, the option may nevertheless be exercised for the excess shares in such calendar year as a Non-Statutory Option. - Should Optionee hold, in addition to this option, one or more other options to purchase Common Stock which become exercisable for the first time in the same calendar year as this option, then the foregoing limitations on the exercisability of such options as Incentive Options shall be applied on the basis of the order in which such options are granted. 18. LEAVE OF ABSENCE. The following provisions shall apply upon the Optionee's commencement of an authorized leave of absence: (a) The exercise schedule in effect under the Grant Notice shall be frozen as of the first day of the authorized leave, and this option shall not become exercisable for any additional installments of the Option Shares during the period Optionee remains on such leave. 7. 8 (b) Should Optionee resume active Employee status within sixty (60) days after the start date of the authorized leave, Optionee shall, for purposes of the exercise schedule set forth in the Grant Notice, receive Service credit for the entire period of such leave. If Optionee does not resume active Employee status within such sixty (60)-day period, then no Service credit shall be given for the period of such leave. (c) If the option is designated as an Incentive Option in the Grant Notice, then the following additional provision shall apply: - If the leave of absence continues for more than three (3) months, then this option shall automatically convert to a Non-Statutory Option under the Federal tax laws at the end of such three (3)-month period, unless the Optionee's reemployment rights are guaranteed by statute or by written agreement. Following any such conversion of the option, all subsequent exercises of such option, whether effected before or after Optionee's return to active Employee status, shall result in an immediate taxable event, and the Corporation shall be required to collect from Optionee the Federal, state and local income and employment withholding taxes applicable to such exercise. (d) In no event shall this option become exercisable for any additional Option Shares or otherwise remain outstanding if Optionee does not resume Employee status prior to the Expiration Date of the option term. 8. 9 EXHIBIT I NOTICE OF EXERCISE I hereby notify Calpine Corporation (the "Corporation") that I elect to purchase __________ shares of the Corporation's Common Stock (the "Purchased Shares") at the option exercise price of $ __________ per share (the "Exercise Price") pursuant to that certain option (the "Option") granted to me under the Corporation's 1996 Stock Incentive Plan on _______________, 199__ .

In return for the surrendered Option, Optionee shall receive a cash distribution from the Corporation in an amount equal to the excess of (A) the Take-Over Price of the shares of Common Stock which are at the time vested under the surrendered Option (or surrendered portion) over (B) the aggregate Exercise Price payable for such shares. - To exercise this limited stock appreciation right, Optionee must, during the applicable thirty (30)-day exercise period, provide the Corporation with written notice of the option surrender in which there is specified the number of Option Shares as to which the Option is being surrendered.

(ii) Should Optionee die while this option is outstanding, then the personal representative of Optionee's estate or the person or persons to whom the option is transferred pursuant to Optionee's will or in accordance with the laws of descent and distribution shall have the right to exercise this option. Such right shall lapse and this option shall cease to be outstanding upon the earlier of (i) the expiration of the two (2)-year period measured from the date of Optionee's cessation of Service or (ii) the Expiration Date. (iii) During the applicable post-Service exercise period, this option may not be exercised in the aggregate for more than the number of Option Shares for which the option is exercisable at the time of Optionee's cessation of Service. Upon the expiration of such limited exercise period or (if earlier) upon the Expiration Date, this option shall terminate and cease to be outstanding for any exercisable Option Shares for which the option has not been exercised. However, this option shall immediately, upon Optionee's cessation of Service for any reason, terminate and cease to be outstanding with respect to any and all Option Shares for which the option is not otherwise at that time exercisable. (iv) In the event of a Corporate Transaction or Change in Control, the provisions of Paragraph 6 or Paragraph 7 shall govern the period for which this option is to remain exercisable following Optionee's cessation of Service and shall supersede any provisions to the contrary in this Paragraph 5. 2. 3 6. CORPORATE TRANSACTION. (a) This option, to the extent outstanding at the time of a Corporate Transaction but not otherwise fully exercisable for all the Option Shares, shall automatically accelerate so that this option shall, immediately prior to the effective date of such Corporate Transaction, become exercisable for all the Option Shares at the time subject to this option and may be exercised for any or all of those Option Shares as fully-vested shares of Common Stock. (b) This option shall be assumed by the successor corporation (or parent thereof) in connection with such Corporate Transaction and shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. (c) This option, as so accelerated and assumed, shall remain exercisable until the earlier of (i) the expiration of the two (2)-year period measured from the date of Optionee's cessation of Service or (ii) the specified Expiration Date. (d) This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 7. CHANGE IN CONTROL/HOSTILE TAKE-OVER. (a) All Option Shares subject to this option at the time of a Change in Control but not otherwise vested shall automatically vest so that this option shall, immediately prior to the effective date of such Change in Control, become fully exercisable for all of the Option Shares at the time subject to this option and may be exercised for all or any portion of such shares as fully-vested shares of Common Stock. This option shall remain exercisable for such fully-vested Option Shares until the earliest to occur of (i) the specified Expiration Date, (ii) the sooner termination of this option in accordance with Paragraph 5 or 6 or (iii) the surrender of this option under Paragraph 7(b). (b) Optionee shall have an unconditional right (exercisable during the thirty (30)-day period immediately following the consummation of a Hostile Take-Over) to surrender this option to the Corporation in exchange for a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over Price of the Option Shares at the time subject to the surrendered option (whether or not those Option Shares are otherwise at the time vested) over (ii) the aggregate Exercise Price payable for such shares. This Paragraph 7(b) limited stock appreciation right shall in all events terminate 3. 4 upon the expiration or sooner termination of the option term and may not be assigned or transferred by Optionee. (c) To exercise the Paragraph 7(b) limited stock appreciation right, Optionee must, during the applicable thirty (30)-day exercise period, provide the Corporation with written notice of the option surrender in which there is specified the number of Option Shares as to which the option is being surrendered. Such notice must be accompanied by the return of Optionee's copy of this Agreement, together with any written amendments to such Agreement. The cash distribution shall be paid to Optionee within five (5) business days following such delivery date, and neither the approval of the Plan Administrator nor the consent of the Board shall be required in connection with such option surrender and cash distribution. Upon receipt of such cash distribution, this option shall be cancelled with respect to the shares subject to the surrendered option (or the surrendered portion), and Optionee shall cease to have any further right to acquire those Option Shares under this Agreement. The option shall, however, remain outstanding for the balance of the Option Shares (if any) in accordance with the terms and provisions of this Agreement, and the Corporation shall accordingly issue a new stock option agreement (substantially in the same form as this Agreement) for those remaining Option Shares. 8. STOCKHOLDER RIGHTS. The holder of this option shall not have any stockholder rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become a holder of record of the purchased shares. 9. ADJUSTMENT IN OPTION SHARES. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the number and/or class of securities subject to this option and (ii) the Exercise Price in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder. 10. MANNER OF EXERCISING OPTION. (a) In order to exercise this option with respect to all or any part of the Option Shares for which this option is at the time exercisable, Optionee (or any other person or persons exercising the option) must take the following actions: (i) Execute and deliver to the Corporation a Notice of Exercise for the number of Option Shares for which the option is exercised. (ii) Pay the aggregate Exercise Price for the purchased shares in one or more of the following forms: 4. 5 (A) cash or check made payable to the Corporation; (B) shares of Common Stock held by Optionee (or any other person or persons exercising the option) for the requisite period necessary to avoid a charge to the Corporation's earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date; or (C) through a special sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising the option) shall concurrently provide irrevocable written instructions (I) to a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes required to be withheld by the Corporation by reason of such exercise and (II) to the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale. Except to the extent the sale and remittance procedure is utilized in connection with the option exercise, payment of the Exercise Price must accompany the Notice of Exercise. (iii) Furnish to the Corporation appropriate documentation that the person or persons exercising the option (if other than Optionee) have the right to exercise this option. (iv) Make appropriate arrangements with the Corporation (or Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all Federal, state and local income and employment tax withholding requirements applicable to the option exercise. (b) As soon as practical after the Exercise Date, the Corporation shall issue to or on behalf of Optionee (or any other person or persons exercising this option) a certificate for the purchased Option Shares. (c) In no event may this option be exercised for any fractional shares. 5. 6 11. COMPLIANCE WITH LAWS AND REGULATIONS. (a) The exercise of this option and the issuance of the Option Shares upon such exercise shall be subject to compliance by the Corporation and Optionee with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange (or the Nasdaq National Market, if applicable) on which the Common Stock may be listed for trading at the time of such exercise and issuance. (b) The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the Corporation to be necessary to the lawful issuance and sale of any Common Stock pursuant to this option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. The Corporation, however, shall use its best efforts to obtain all such approvals. 12. SUCCESSORS AND ASSIGNS. Except to the extent otherwise provided in Paragraph 3, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Optionee, Optionee's assigns and the legal representatives, heirs and legatees of Optionee's estate. 13.

GOVERNING LAW. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of California without resort to that State's conflict-of-laws rules. 16. EXCESS SHARES. If the Option Shares covered by this Agreement exceed, as of the Grant Date, the number of shares of Common Stock which may without stockholder approval be issued under the Plan, then this option shall be void with respect to such excess shares, unless stockholder approval of an amendment sufficiently increasing the number of shares of Common Stock issuable under the Plan is obtained in accordance with the provisions of the Plan. 6. 7 17. LEAVE OF ABSENCE. The following provisions shall apply upon the Optionee's commencement of an authorized leave of absence: (i) The exercise schedule in effect under the Grant Notice shall be frozen as of the first day of the authorized leave, and the option shall not become exercisable for any additional installments of the Option Shares during the period Optionee remains on such leave. (ii) Should Optionee resume active Employee status within sixty (60) days after the start date of the authorized leave, Optionee shall, for purposes of the exercise schedule set forth in the Grant Notice, receive Service credit for the entire period of such leave. If Optionee does not resume active Employee status within such sixty (60)-day period, then Service credit shall be given for the period of the leave. (iii) If the option is designated as an Incentive Stock Option in the Grant Notice, then the following additional provision shall apply: (A) If the leave of absence continues for more than ninety (90) days, then the option shall automatically convert to a non-qualified option under the federal tax laws on the ninety-first (91st) day of such leave, unless the Optionee's reemployment rights are guaranteed by statute or by written agreement. Following any such conversion of the option, all subsequent exercises of such option, whether effected before or after Optionee's return to active Employee status, shall result in an immediate taxable event, and the Corporation shall be required to collect from Optionee the federal, state and local income and employment withholding taxes applicable to such exercise. (iv) In no event shall this option become exercisable for any additional Option Shares or otherwise remain outstanding if Optionee does not resume Employee status prior to the Expiration Date of the option term. 7. 8 APPENDIX The following definitions shall be in effect under the Agreement: A.

STOCKHOLDER RIGHTS. Until such time as the Corporation exercises the Repurchase Right, Participant (or any successor in interest) shall have all the rights of a stockholder (including voting, dividend and liquidation rights) with respect to the Purchased Shares, subject, however, to the transfer restrictions of this Agreement. 4.

A copy of such agreement is maintained at the Corporation's principal corporate offices." 3. TRANSFEREE OBLIGATIONS. Each person (other than the Corporation) to whom the Purchased Shares are transferred by means of a Permitted Transfer must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Corporation that such person is bound by the provisions of this Agreement and that the transferred shares are subject to the Repurchase Right to the same extent such shares would be so subject if retained by Participant. C. REPURCHASE RIGHT 1. GRANT. The Corporation is hereby granted the right (the "Repurchase Right"), exercisable at any time during the ninety (90)-day period following the date Participant ceases for any reason to remain in Service, to repurchase at the Purchase Price all or any portion of the Purchased Shares in which Participant is not, at the time of his or her cessation of Service, vested in accordance with the Vesting Schedule (such shares to be hereinafter referred to as the "Unvested Shares"). 2. EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right shall be exercisable by written notice delivered to each Owner of the Unvested Shares prior to the expiration of the ninety (90)-day exercise period. The notice shall indicate the number of Unvested Shares to be repurchased and the date on which the repurchase is to be effected, such date to be not more than thirty (30) days after the date of such notice. The certificates representing the Unvested Shares to be repurchased shall be delivered to the Corporation prior to the close of business on the date specified for the repurchase. Concurrently with the receipt of such stock certificates, the Corporation shall pay to Owner, in cash or cash equivalent (including the cancellation of any purchase-money indebtedness), an amount equal to the Purchase Price previously paid for the Unvested Shares to be repurchased from Owner. 3. TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall terminate with respect to any Unvested Shares for which it is not timely exercised under Paragraph C.2.

RECAPITALIZATION. Any new, substituted or additional securities or other property (including cash paid other than as a regular cash dividend) which is by reason of any Recapitalization distributed with respect to the Purchased Shares shall be immediately subject to the Repurchase Right, but only to the extent the Purchased Shares are at the time covered by such right. Appropriate adjustments to reflect such distribution shall be made to the number and/or class of securities subject to this Agreement and to the price per share to be paid upon the exercise of the Repurchase Right in order to reflect the effect of any such Recapitalization upon the Corporation's capital structure; provided, however, that the aggregate purchase price shall remain the same. 5. CORPORATE TRANSACTION. (a) Immediately prior to the consummation of any Corporate Transaction, the Repurchase Right shall automatically lapse in its entirety and the Purchased Shares shall vest in full, except to the extent the Repurchase Right is to be assigned to the successor corporation (or parent thereof) in connection with the Corporate Transaction. (b) To the extent the Repurchase Right remains in effect following a Corporate Transaction, such right shall apply to the new capital stock or other property (including any cash payments) received in exchange for the Purchased Shares in consummation of the Corporate Transaction, but only to the extent the Purchased Shares are at the time covered by such right. Appropriate adjustments shall be made to the price per share payable upon exercise of the Repurchase Right to reflect the effect of the Corporate Transaction upon the Corporation's capital structure; provided, however, that the aggregate purchase price shall remain the same. D. SPECIAL TAX ELECTION 1. SECTION 83(b) ELECTION . Under Code Section 83, the excess of the fair market value of the Purchased Shares on the date any forfeiture restrictions applicable to such shares lapse over the Purchase Price paid for such shares will be reportable as ordinary 3. 4 income on the lapse date. For this purpose, the term "forfeiture restrictions" includes the right of the Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right. Participant may elect under Code Section 83(b) to be taxed at the time the Purchased Shares are acquired, rather than when and as such Purchased Shares cease to be subject to such forfeiture restrictions. Such election must be filed with the Internal Revenue Service within thirty (30) days after the date of this Agreement. Even if the fair market value of the Purchased Shares on the date of this Agreement equals the Purchase Price paid (and thus no tax is payable), the election must be made to avoid adverse tax consequences in the future. THE FORM FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO. PARTICIPANT UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE FORFEITURE RESTRICTIONS LAPSE. 2. FILING RESPONSIBILITY. PARTICIPANT ACKNOWLEDGES THAT IT IS PARTICIPANT'S SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN IF PARTICIPANT REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF. E. GENERAL PROVISIONS 1. ASSIGNMENT. The Corporation may assign the Repurchase Right to any person or entity selected by the Board, including (without limitation) one or more stockholders of the Corporation. 2. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement or in the Plan shall confer upon Participant 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 Corporation (or any Parent or Subsidiary employing or retaining Participant) or of Participant, which rights are hereby expressly reserved by each, to terminate Participant's Service at any time for any reason, with or without cause. 3. NOTICES. Any notice required to be given under this Agreement shall be in writing and shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, registered or certified, postage prepaid and properly addressed to the party entitled to such notice at the address indicated below such party's signature line on this Agreement or at such other address as such party may designate by ten (10) days advance written notice under this paragraph to all other parties to this Agreement. 4. NO WAIVER. The failure of the Corporation in any instance to exercise the Repurchase Right shall not constitute a waiver of any other repurchase rights that may subsequently arise under the provisions of this Agreement or any other agreement between the Corporation and Participant. No waiver of any breach or condition of this Agreement 4. 5 shall be deemed to be a waiver of any other or subsequent breach or condition, whether of like or different nature. 5. CANCELLATION OF SHARES. If the Corporation shall make available, at the time and place and in the amount and form provided in this Agreement, the consideration for the Purchased Shares to be repurchased in accordance with the provisions of this Agreement, then from and after such time, the person from whom such shares are to be repurchased shall no longer have any rights as a holder of such shares (other than the right to receive payment of such consideration in accordance with this Agreement). Such shares shall be deemed purchased in accordance with the applicable provisions hereof, and the Corporation shall be deemed the owner and holder of such shares, whether or not the certificates therefor have been delivered as required by this Agreement. F. MISCELLANEOUS PROVISIONS 1. PARTICIPANT UNDERTAKING. Participant hereby agrees to take whatever additional action and execute whatever additional documents the Corporation may deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on either Participant or the Purchased Shares pursuant to the provisions of this Agreement. 2.

The provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and upon Participant, Participant's assigns and the legal representatives, heirs and legatees of Participant's estate, whether or not any such person shall have become a party to this Agreement and have agreed in writing to join herein and be bound by the terms hereof. IN WITNESS WHEREOF, the parties have executed this Agreement on the day and year first indicated above. 5. 6 CALPINE CORPORATION By: Title: Address: PARTICIPANT Address: 6. 7 SPOUSAL ACKNOWLEDGMENT The undersigned spouse of the Participant has read and hereby approves the foregoing Stock Issuance Agreement.

The Corporation has implemented an automatic option grant program under the Corporation's 1996 Stock Incentive Plan pursuant to which eligible non-employee members of the Corporation's Board will automatically receive special option grants at designated intervals over their period of Board service in order to provide such individuals with a meaningful incentive to continue to serve as a member of the Board. B. Optionee is an eligible non-employee Board member, and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the automatic grant of a stock option to purchase shares of the Corporation's Common Stock under the Plan. C. The granted option is intended to be a non-statutory option which does not meet the requirements of Section 422 of the Internal Revenue Code. D. All capitalized terms in this Agreement, to the extent not otherwise defined in the Agreement, shall have the meaning assigned to them in the attached Appendix. NOW, THEREFORE, it is hereby agreed as follows: 1. GRANT OF OPTION. The Corporation hereby grants to Optionee, as of the Grant Date, a Non-Statutory Option to purchase up to the number of Option Shares specified in the Grant Notice. The Option Shares shall be purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price. 2. OPTION TERM. This option shall have a maximum term of ten (10) years measured from the Grant Date and shall accordingly expire at the close of business on the Expiration Date, unless sooner terminated in accordance with Paragraph 5, 6 or 7. 3. LIMITED TRANSFERABILITY. This option may, in connection with the Optionee's estate plan, be assigned in whole or in part during Optionee's lifetime to one or more members of the Optionee's immediate family or to a trust established for the exclusive benefit of one or more such family members. The assigned portion shall be exercisable only by the person or persons who acquire a proprietary interest in the option pursuant to such assignment. The terms applicable to the assigned portion shall be the same as those in effect for this option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Corporation may deem appropriate. Should the Optionee die while holding this option, then this option shall be transferred in accordance with Optionee's will or the laws of descent and distribution. 2 4. EXERCISABILITY/VESTING. (a) This option shall be immediately exercisable for any or all of the Option Shares, whether or not the Option Shares are vested in accordance with the Vesting Schedule set forth in the Grant Notice, and shall remain so exercisable until the Expiration Date or the sooner termination of the option term under Paragraph 5, 6 or 7. (b) Optionee shall, in accordance with the Vesting Schedule set forth in the Grant Notice, vest in the Option Shares in a series of installments over his or her period of Board service. Vesting in the Option Shares may be accelerated pursuant to the provisions of Paragraph 5, 6 or 7. In no event, however, shall any additional Option Shares vest following Optionee's cessation of service as a Board member. 5. CESSATION OF BOARD SERVICE. Should Optionee's service as a Board member cease while this option remains outstanding, then the option term specified in Paragraph 2 shall terminate (and this option shall cease to be outstanding) prior to the Expiration Date in accordance with the following provisions: (i) Should Optionee cease to serve as a Board member for any reason (other than death or Permanent Disability) while holding this option, then the period for exercising this option shall be reduced to a twelve (12)-month period commencing with the date of such cessation of Board service, but in no event shall this option be exercisable at any time after the Expiration Date. During such limited period of exercisability, this option may not be exercised in the aggregate for more than the number of Option Shares (if any) in which Optionee is vested on the date of his or her cessation of Board service. Upon the earlier of (i) the expiration of such twelve (12)-month period or (ii) the specified Expiration Date, the option shall terminate and cease to be exercisable with respect to any vested Option Shares for which the option has not been exercised. (ii) Should Optionee die during the twelve (12)- month period following his or her cessation of Board service, then the personal representative of Optionee's estate or the person or persons to whom the option is transferred pursuant to Optionee's will or in accordance with the laws of descent and distribution shall have the right to exercise this option for any or all of the Option Shares in which Optionee is vested at the time of Optionee's cessation of Board service (less any Option Shares purchased by Optionee after such cessation of Board service but prior to death). Such right of exercise shall terminate, and this option shall accordingly cease to be exercisable for such vested Option Shares, upon the earlier of (i) the expiration of the twelve (12)-month period measured from the date of Optionee's cessation of Board service or (ii) the specified Expiration Date of the option term. 2. 3 (iii) Should Optionee cease service as a Board member by reason of death or Permanent Disability, then all Option Shares at the time subject to this option but not otherwise vested shall immediately vest in full so that Optionee (or the personal representative of Optionee's estate or the person or persons to whom the option is transferred upon Optionee's death) shall have the right to exercise this option for any or all of the Option Shares as fully-vested shares of Common Stock at any time prior to the earlier of (i) the expiration of the twelve (12)-month period measured from the date of Optionee's cessation of Board service or (ii) the specified Expiration Date. (iv) Upon Optionee's cessation of Board service for any reason other than death or Permanent Disability, this option shall immediately terminate and cease to be outstanding with respect to any and all Option Shares in which Optionee is not otherwise at that time vested in accordance with the normal Vesting Schedule set forth in the Grant Notice or the special vesting acceleration provisions of Paragraph 6 or 7 below. 6. CORPORATE TRANSACTION. (a) In the event of a Corporate Transaction, all Option Shares at the time subject to this option but not otherwise vested shall automatically vest so that this option shall, immediately prior to the specified effective date for the Corporate Transaction, become fully exercisable for all of the Option Shares at the time subject to this option and may be exercised for all or any portion of such shares as fully-vested shares of Common Stock. Immediately following the consummation of the Corporate Transaction, this option shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation or its parent company. (b) If this option is assumed in connection with a Corporate Transaction, then this option shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. 7. CHANGE IN CONTROL/HOSTILE TAKE-OVER. (a) All Option Shares subject to this option at the time of a Change in Control but not otherwise vested shall automatically vest so that this option shall, immediately prior to the effective date of such Change in Control, become fully exercisable for all of the Option Shares at the time subject to this option and may be exercised for all or any portion of such shares as fully-vested shares of Common Stock. This option shall remain exercisable for such fully-vested Option Shares until the earliest to occur of (i) the 3. 4 specified Expiration Date, (ii) the sooner termination of this option in accordance with Paragraph 5 or 6 or (iii) the surrender of this option under Paragraph 7(b). (b) Optionee shall have an unconditional right (exercisable during the thirty (30)-day period immediately following the consummation of a Hostile Take-Over) to surrender this option to the Corporation in exchange for a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over Price of the Option Shares at the time subject to the surrendered option (whether or not those Option Shares are otherwise at the time vested) over (ii) the aggregate Exercise Price payable for such shares. This Paragraph 7(b) limited stock appreciation right shall in all events terminate upon the expiration or sooner termination of the option term and may not be assigned or transferred by Optionee. (c) To exercise the Paragraph 7(b) limited stock appreciation right, Optionee must, during the applicable thirty (30)-day exercise period, provide the Corporation with written notice of the option surrender in which there is specified the number of Option Shares as to which the option is being surrendered. Such notice must be accompanied by the return of Optionee's copy of this Agreement, together with any written amendments to such Agreement. The cash distribution shall be paid to Optionee within five (5) business days following such delivery date, and neither the approval of the Plan Administrator nor the consent of the Board shall be required in connection with such option surrender and cash distribution. Upon receipt of such cash distribution, this option shall be cancelled with respect to the shares subject to the surrendered option (or the surrendered portion), and Optionee shall cease to have any further right to acquire those Option Shares under this Agreement. The option shall, however, remain outstanding for the balance of the Option Shares (if any) in accordance with the terms and provisions of this Agreement, and the Corporation shall accordingly issue a new stock option agreement (substantially in the same form as this Agreement) for those remaining Option Shares. 8. ADJUSTMENT IN OPTION SHARES. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the number and/or class of securities subject to this option and (ii) the Exercise Price in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder; provided, however, that the aggregate Exercise Price shall remain the same. 9. STOCKHOLDER RIGHTS. The holder of this option shall not have any stockholder rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become a holder of record of the purchased shares. 4. 5 10. MANNER OF EXERCISING OPTION. (a) In order to exercise this option for all or any part of the Option Shares for which the option is at the time exercisable, Optionee or, in the case of exercise after Optionee's death, Optionee's executor, administrator, heir or legatee, as the case may be, must take the following actions: (i) To the extent the option is exercised for vested Option Shares, the Secretary of the Corporation shall be provided with written notice of the option exercise (the "Exercise Notice") in substantially the form of Exhibit I attached hereto, in which there is specified the number of vested Option Shares to be purchased under the exercised option. To the extent that the option is exercised for one or more unvested Option Shares, Optionee (or other person exercising the option) shall deliver to the Secretary of the Corporation a Purchase Agreement for those unvested Option Shares. (ii) The Exercise Price for the purchased shares shall be paid in one or more of the following alternative forms: - cash or check made payable to the Corporation's order; or - shares of Common Stock held by Optionee (or any other person or persons exercising the option) for the requisite period necessary to avoid a charge to the Corporation's earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date; or - to the extent the option is exercised for vested Option Shares, through a special sale and remittance procedure pursuant to which Optionee shall provide irrevocable written instructions (A) to a Corporation-designated brokerage firm to effect the immediate sale of the vested shares purchased under the option and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for those shares plus the applicable Federal, state and local income taxes required to be withheld by the Corporation by reason of such exercise and (B) to the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale. (iii) Appropriate documentation evidencing the right to exercise this option shall be furnished the Corporation if the person or persons exercising the option is other than Optionee. 5. 6 (iv) Appropriate arrangement must be made with the Corporation for the satisfaction of all Federal, state and local income tax withholding requirements applicable to the option exercise. (b) Except to the extent the sale and remittance procedure specified above is utilized in connection with the exercise of the option for vested Option Shares, payment of the Exercise Price for the purchased shares must accompany the Exercise Notice or Purchase Agreement delivered to the Corporation in connection with the option exercise. (c) As soon as practical after the Exercise Date, the Corporation shall issue to or on behalf of Optionee (or any other person or persons exercising this option) a certificate or certificates representing the purchased Option Shares. To the extent any such Option Shares are unvested, the certificates for those Option Shares shall be endorsed with an appropriate legend evidencing the Corporation's repurchase rights and may be held in escrow with the Corporation until such shares vest. (d) In no event may this option be exercised for fractional shares. 11. NO IMPAIRMENT OF RIGHTS. This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise make changes in its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. Nor shall this Agreement in any way be construed or interpreted so as to affect adversely or otherwise impair the right of the Corporation or the stockholders to remove Optionee from the Board at any time in accordance with the provisions of applicable law. 12. COMPLIANCE WITH LAWS AND REGULATIONS. (a) The exercise of this option and the issuance of the Option Shares upon such exercise shall be subject to compliance by the Corporation and Optionee with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange (or the Nasdaq National Market, if applicable) on which the Common Stock may be listed for trading at the time of such exercise and issuance. (b) The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the Corporation to be necessary to the lawful issuance and sale of any Common Stock pursuant to this option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. However, the Corporation shall use its best efforts to obtain all such applicable approvals. 6. 7 13. SUCCESSORS AND ASSIGNS. Except to the extent otherwise provided in Paragraph 3 or 6, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Optionee, Optionee's assigns and the legal representatives, heirs and legatees of Optionee's estate. 14. CONSTRUCTION/GOVERNING LAW. This Agreement and the option evidenced hereby are made and granted pursuant to the automatic option grant program in effect under the Plan and are in all respects limited by and subject to the express terms and provisions of that program. The interpretation, performance, and enforcement of this Agreement shall be governed by the laws of the State of California without resort to that State's conflict-of-laws rules. 15. NOTICES.

The Corporation has implemented a special director fee stock option program under the Plan pursuant to which non-employee Board members may, by prior irrevocable election, apply all or any portion of the annual retainer fee otherwise payable to them in cash to the acquisition of a special stock option grant. B. Optionee is a non-employee Board member who made the requisite election to apply a portion of his retainer fee to the acquisition of the special option, and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the grant of such special option to Optionee. C. All capitalized terms in this Agreement shall have the meaning assigned to them in the attached Appendix. NOW, THEREFORE, it is hereby agreed as follows: 1. GRANT OF OPTION. The Corporation hereby grants to Optionee, as of the Grant Date, a Non-Qualified Option to purchase up to the number of Option Shares specified in the Grant Notice. The Option Shares shall be purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price. 2. OPTION TERM. This option shall have a term of ten (10) years measured from the Grant Date and shall accordingly expire at the close of business on the Expiration Date, unless sooner terminated in accordance with Paragraph 5 or 6. 3. LIMITED TRANSFERABILITY. This option may, in connection with the Optionee's estate plan, be assigned in whole or in part during Optionee's lifetime to one or more members of the Optionee's immediate family or to a trust established for the exclusive benefit of one or more such family members. The assigned portion shall be exercisable only by the person or persons who acquire a proprietary interest in the option pursuant to such assignment. The terms applicable to the assigned portion shall be the same as those in effect for this option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Corporation may deem appropriate. Should the Optionee die while holding this option, then this option shall be transferred in accordance with Optionee's will or the laws of descent and distribution. 2 4. EXERCISABILITY/VESTING. This option shall become exercisable for the Option Shares in installments as specified in the Grant Notice. As the option becomes exercisable for those installments, the installments shall accumulate and the option shall remain exercisable for the accumulated installments until the Expiration Date or sooner termination of the option term under Paragraph 5 or 6. 5. CESSATION OF BOARD SERVICE. Should Optionee's service as a Board member cease while this option remains outstanding, then the option term specified in Paragraph 2 shall terminate (and this option shall cease to be outstanding) prior to the Expiration Date in accordance with the following provisions: (i) Should Optionee cease to serve as a Board member for any reason (other than death or Permanent Disability) while holding this option, then the period for exercising this option shall be reduced to a two (2)-year period (commencing with the date of such cessation of Board service), but in no event shall this option be exercisable at any time after the Expiration Date. During such limited exercise period, this option may not be exercised in the aggregate for more than the number of Option Shares (if any) for which the option is exercisable on the date of Optionee's cessation of Board service. Upon the earlier of (A) the expiration of such two (2)-year period or (B) the specified Expiration Date, the option shall terminate and cease to be exercisable with respect to any exercisable Option Shares for which the option has not been exercised. (ii) Should Optionee cease service as a Board member by reason of death or Permanent Disability, then this option shall automatically accelerate and become immediately exercisable for all the Option Shares at the time subject to this option so that Optionee (or the personal representative of Optionee's estate or the person or persons to whom the option is transferred upon Optionee's death) shall have the right to exercise this option for any or all of those Option Shares as fully-vested shares of Common Stock. Such right shall lapse upon the earlier of (A) the expiration of the two (2)-year period measured from the date of Optionee's cessation of Board service or (B) the specified Expiration Date. (iii) Upon Optionee's cessation of Board service for any reason other than death or Permanent Disability, this option shall immediately terminate and cease to be outstanding with respect to any and all Option Shares for which the option is not otherwise at that time exercisable. (iv) In the event of a Corporate Transaction or Change in Control, the provisions of Paragraph 6 or Paragraph 7 shall govern the period for which this option is to remain exercisable following Optionee's cessation of Board service and shall supersede any provisions to the contrary in this Paragraph 5. 2. 3 6. CORPORATE TRANSACTION. (a) This option, to the extent outstanding at the time of a Corporate Transaction but not otherwise fully exercisable for all the Option Shares, shall automatically accelerate so that this option shall, immediately prior to the effective date of such Corporate Transaction, become exercisable for all the Option Shares at the time subject to this option and may be exercised for any or all of those Option Shares as fully-vested shares of Common Stock. (b) This option shall be assumed by the successor corporation (or parent thereof) in connection with such Corporate Transaction and shall be appropriately adjusted, immediately after such Corporate Transaction, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Corporate Transaction had the option been exercised immediately prior to such Corporate Transaction, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. (c) This option, as so accelerated and assumed, shall remain exercisable until the earlier of (i) the expiration of the two (2)-year period measured from the date of Optionee's cessation of Board service or (ii) the specified Expiration Date. (d) This Agreement shall not in any way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 7. CHANGE IN CONTROL/HOSTILE TAKE-OVER. (a) All Option Shares subject to this option at the time of a Change in Control but not otherwise vested shall automatically vest so that this option shall, immediately prior to the effective date of such Change in Control, become fully exercisable for all of the Option Shares at the time subject to this option and may be exercised for all or any portion of such shares as fully-vested shares of Common Stock. This option shall remain exercisable for such fully-vested Option Shares until the earliest to occur of (i) the specified Expiration Date, (ii) the sooner termination of this option in accordance with Paragraph 5 or 6 or (iii) the surrender of this option under Paragraph 7(b). (b) Optionee shall have an unconditional right (exercisable during the thirty (30)-day period immediately following the consummation of a Hostile Take-Over) to surrender this option to the Corporation in exchange for a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over Price of the Option Shares at the time subject to the surrendered option (whether or not those Option Shares are otherwise at the time vested) over (ii) the aggregate Exercise Price payable for such shares. This Paragraph 7(b) limited stock appreciation right shall in all events terminate 3. 4 upon the expiration or sooner termination of the option term and may not be assigned or transferred by Optionee. (c) To exercise the Paragraph 7(b) limited stock appreciation right, Optionee must, during the applicable thirty (30)-day exercise period, provide the Corporation with written notice of the option surrender in which there is specified the number of Option Shares as to which the option is being surrendered. Such notice must be accompanied by the return of Optionee's copy of this Agreement, together with any written amendments to such Agreement. The cash distribution shall be paid to Optionee within five (5) business days following such delivery date, and neither the approval of the Plan Administrator nor the consent of the Board shall be required in connection with such option surrender and cash distribution. Upon receipt of such cash distribution, this option shall be cancelled with respect to the shares subject to the surrendered option (or the surrendered portion), and Optionee shall cease to have any further right to acquire those Option Shares under this Agreement. The option shall, however, remain outstanding for the balance of the Option Shares (if any) in accordance with the terms and provisions of this Agreement, and the Corporation shall accordingly issue a new stock option agreement (substantially in the same form as this Agreement) for those remaining Option Shares. 8. STOCKHOLDER RIGHTS. The holder of this option shall not have any stockholder rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become a holder of record of the purchased shares. 9. ADJUSTMENT IN OPTION SHARES. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the number and/or class of securities subject to this option and (ii) the Exercise Price in order to reflect such change and thereby preclude a dilution or enlargement of benefits hereunder. 10. MANNER OF EXERCISING OPTION. (a) In order to exercise this option with respect to all or any part of the Option Shares for which this option is at the time exercisable, Optionee (or any other person or persons exercising the option) must take the following actions: (i) Execute and deliver to the Corporation a Notice of Exercise for the Option Shares for which the option is exercised. (ii) Pay the aggregate Exercise Price for the purchased shares in one or more of the following forms: 4. 5 (A) cash or check made payable to the Corporation, (B) shares of Common Stock held by Optionee (or any other person or persons exercising the option) for the requisite period necessary to avoid a charge to the Corporation's earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date, or (C) through a special sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising the option) shall concurrently provide irrevocable written instructions (I) to a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate Exercise Price payable for the purchased shares plus all applicable Federal, state and local income taxes required to be withheld by the Corporation by reason of such exercise and (II) to the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale. Except to the extent the sale and remittance procedure is utilized in connection with the option exercise, payment of the Exercise Price must accompany the Notice of Exercise. (iii) Furnish to the Corporation appropriate documentation that the person or persons exercising the option (if other than Optionee) have the right to exercise this option. (b) As soon after the Exercise Date as practical, the Corporation shall issue to or on behalf of Optionee (or any other person or persons exercising this option) a certificate for the purchased Option Shares, with the appropriate legends affixed thereto. (c) In no event may this option be exercised for any fractional shares. 5. 6 11. COMPLIANCE WITH LAWS AND REGULATIONS.

(b) The inability of the Corporation to obtain approval from any regulatory body having authority deemed by the Corporation to be necessary to the lawful issuance and sale of any Common Stock pursuant to this option shall relieve the Corporation of any liability with respect to the non-issuance or sale of the Common Stock as to which such approval shall not have been obtained. The Corporation, however, shall use its best efforts to obtain all such approvals. 12. SUCCESSORS AND ASSIGNS. Except to the extent otherwise provided in Paragraph 3, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Corporation and its successors and assigns and Optionee, Optionee's assigns and the legal representatives, heirs and legatees of Optionee's estate. 13.

PURPOSE OF THE PLAN This Employee Stock Purchase Plan is intended to promote the interests of Calpine Corporation by providing eligible employees with the opportunity to acquire a proprietary interest in the Corporation through participation in a payroll-deduction based employee stock purchase plan designed to qualify under Section 423 of the Code. Capitalized terms herein shall have the meanings assigned to such terms in the attached Appendix. II. ADMINISTRATION OF THE PLAN The Plan Administrator shall have full authority to interpret and construe any provision of the Plan and to adopt such rules and regulations for administering the Plan as it may deem necessary in order to comply with the requirements of Code Section 423. Decisions of the Plan Administrator shall be final and binding on all parties having an interest in the Plan. III. STOCK SUBJECT TO PLAN A. The stock purchasable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares of Common Stock purchased on the open market. The maximum number of shares of Common Stock which may be issued over the term of the Plan shall not exceed Two Hundred Seventy Five Thousand (275,000) shares. B. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the maximum number and class of securities issuable under the Plan, (ii) the maximum number and class of securities purchasable per Participant on any one Purchase Date and (iii) the number and class of securities and the price per share in effect under each outstanding purchase right in order to prevent the dilution or enlargement of benefits thereunder. 2 IV. OFFERING PERIODS A. Shares of Common Stock shall be offered for purchase under the Plan through a series of successive offering periods until such time as (i) the maximum number of shares of Common Stock available for issuance under the Plan shall have been purchased or (ii) the Plan shall have been sooner terminated. B. Each offering period shall be of such duration (not to exceed twenty-four (24) months) as determined by the Plan Administrator prior to the start date. The initial offering period shall commence at the Effective Time and terminate on the last business day in August 1998. The next offering period shall commence on the first business day in September 1998, and subsequent offering periods shall commence as designated by the Plan Administrator. C. Each offering period shall be comprised of a series of one or more successive Purchase Intervals. Purchase Intervals shall run from the first business day in March each year to the last business day in August of the same year and from the first business day in September each year to the last business day in February of the following year. Accordingly, the first Purchase Interval in effect under the initial offering period shall commence at the Effective Time and terminate on the last business day in February 1997. D. Should the Fair Market Value per share of Common Stock on any Purchase Date within an offering period be less than the Fair Market Value per share of Common Stock on the start date of that offering period, then that offering period shall automatically terminate immediately after the purchase of shares of Common Stock on such Purchase Date, and a new offering period shall commence on the next business day following such Purchase Date. The new offering period shall have a duration of twenty four (24) months, unless a shorter duration is established by the Plan Administrator within five (5) business days following the start date of that offering period. V. ELIGIBILITY A. Each individual who is an Eligible Employee on the start date of any offering period under the Plan may enter that offering period on such start date or on any subsequent Semi-Annual Entry Date within that offering period, provided he or she remains an Eligible Employee. B. Each individual who first becomes an Eligible Employee after the start date of an offering period may enter that offering period on any subsequent Semi-Annual Entry Date within that offering period on which he or she is an Eligible Employee. C. The date an individual enters an offering period shall be designated his or her Entry Date for purposes of that offering period. 2. 3 D. To participate in the Plan for a particular offering period, the Eligible Employee must complete the enrollment forms prescribed by the Plan Administrator (including a stock purchase agreement and a payroll deduction authorization) and file such forms with the Plan Administrator (or its designate) on or before his or her scheduled Entry Date. VI. PAYROLL DEDUCTIONS A. The Plan Administrator shall, prior to the start of each offering period, determine the maximum percentage of Cash Earnings which each Participant may contribute to the Plan through payroll deductions during that offering period; provided, however, that the maximum percentage shall in no event exceed fifteen percent (15%) of such Cash Earnings. Each Participant may then authorize a level of payroll deduction to be in effect for such offering period in any multiple of one percent (1%) of the Cash Earnings paid to him or her during each Purchase Interval within that offering period, up to the maximum percentage established by the Plan Administrator for such offering period. The deduction rate authorized by the Participant shall continue in effect throughout the offering period, except to the extent such rate is changed in accordance with the following guidelines: (i) The Participant may, at any time during the offering period, reduce his or her rate of payroll deduction to become effective as soon as possible after filing the appropriate form with the Plan Administrator. The Participant may not, however, effect more than one (1) such reduction per Purchase Interval. (ii) The Participant may, prior to the commencement of any new Purchase Interval within the offering period, increase the rate of his or her payroll deduction by filing the appropriate form with the Plan Administrator. The new rate (which may not exceed the maximum percentage authorized by the Plan Administrator for that offering period) shall become effective on the start date of the first Purchase Interval following the filing of such form. B. Payroll deductions shall begin on the first pay day following the Participant's Entry Date into the offering period and shall (unless sooner terminated by the Participant) continue through the pay day ending with or immediately prior to the last day of that offering period; provided however, that for the initial offering period, payroll deductions shall not begin for any Participant until the first payday which is at least three (3) business days after the start date of such offering period. The amounts so collected shall be credited to the Participant's book account under the Plan, but no interest shall be paid on the balance from time to time outstanding in such account. The amounts collected from the Participant shall not be held in any segregated account or trust fund and may be commingled with the general assets of the Corporation and used for general corporate purposes. 3. 4 C. Payroll deductions shall automatically cease upon the termination of the Participant's purchase right in accordance with the provisions of the Plan. D. The Participant's acquisition of Common Stock under the Plan on any Purchase Date shall neither limit nor require the Participant's acquisition of Common Stock on any subsequent Purchase Date, whether within the same or a different offering period. VII. PURCHASE RIGHTS A. GRANT OF PURCHASE RIGHT. A Participant shall be granted a separate purchase right for each offering period in which he or she participates. The purchase right shall be granted on the Participant's Entry Date into the offering period and shall provide the Participant with the right to purchase shares of Common Stock, in a series of successive installments over the remainder of such offering period, upon the terms set forth below. The Participant shall execute a stock purchase agreement embodying such terms and such other provisions (not inconsistent with the Plan) as the Plan Administrator may deem advisable. Under no circumstances shall purchase rights be granted under the Plan to any Eligible Employee if such individual would, immediately after the grant, own (within the meaning of Code Section 424(d)) or hold outstanding options or other rights to purchase, stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Corporation or any Corporate Affiliate. B. EXERCISE OF THE PURCHASE RIGHT. Each purchase right shall be automatically exercised in installments on each successive Purchase Date within the offering period, and shares of Common Stock shall accordingly be purchased on behalf of each Participant (other than Participants whose payroll deductions have previously been refunded pursuant to the Termination of Purchase Right provisions below) on each such Purchase Date. The purchase shall be effected by applying the Participant's payroll deductions for the Purchase Interval ending on such Purchase Date to the purchase of whole shares of Common Stock at the purchase price in effect for the Participant for that Purchase Date. C. PURCHASE PRICE. The purchase price per share at which Common Stock will be purchased on the Participant's behalf on each Purchase Date within the offering period shall be equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of Common Stock on the Participant's Entry Date into that offering period or (ii) the Fair Market Value per share of Common Stock on that Purchase Date. D. NUMBER OF PURCHASABLE SHARES. The number of shares of Common Stock purchasable by a Participant on each Purchase Date during the offering period shall be the number of whole shares obtained by dividing the amount collected from the Participant through payroll deductions during the Purchase Interval ending with that Purchase Date by the purchase price in effect for the Participant for that Purchase Date. 4. 5 However, the maximum number of shares of Common Stock purchasable per Participant on any one Purchase Date shall not exceed three hundred (300) shares, subject to periodic adjustments in the event of certain changes in the Corporation's capitalization. E. EXCESS PAYROLL DEDUCTIONS. Any payroll deductions not applied to the purchase of shares of Common Stock on any Purchase Date because they are not sufficient to purchase a whole share of Common Stock shall be held for the purchase of Common Stock on the next Purchase Date. However, any payroll deductions not applied to the purchase of Common Stock by reason of the limitation on the maximum number of shares purchasable by the Participant on the Purchase Date shall be promptly refunded. F. TERMINATION OF PURCHASE RIGHT. The following provisions shall govern the termination of outstanding purchase rights: (i) A Participant may, at any time prior to the next scheduled Purchase Date in the offering period, terminate his or her outstanding purchase right by filing the appropriate form with the Plan Administrator (or its designate), and no further payroll deductions shall be collected from the Participant with respect to the terminated purchase right. Any payroll deductions collected during the Purchase Interval in which such termination occurs shall, at the Participant's election, be immediately refunded or held for the purchase of shares on the next Purchase Date. If no such election is made at the time such purchase right is terminated, then the payroll deductions collected with respect to the terminated right shall be refunded as soon as possible. (ii) The termination of such purchase right shall be irrevocable, and the Participant may not subsequently rejoin the offering period for which the terminated purchase right was granted. In order to resume participation in any subsequent offering period, such individual must re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before his or her scheduled Entry Date into that offering period. (iii) Should the Participant cease to remain an Eligible Employee for any reason (including death, disability or change in status) while his or her purchase right remains outstanding, then that purchase right shall immediately terminate, and all of the Participant's payroll deductions for the Purchase Interval in which the purchase right so terminates shall be immediately refunded. However, should the Participant cease to remain in active service by reason of an approved unpaid leave of absence, then the Participant shall have the right, exercisable up until the last business day of the Purchase Interval in which such leave commences, to (a) withdraw all the payroll deductions collected to date on his or her behalf for that Purchase 5. 6 Interval or (b) have such funds held for the purchase of shares on his or her behalf on the next scheduled Purchase Date. In no event, however, shall any further payroll deductions be collected on the Participant's behalf during such leave. Upon the Participant's return to active service, his or her payroll deductions under the Plan shall automatically resume at the rate in effect at the time the leave began, unless the Participant withdraws from the Plan prior to his or her return. G. CORPORATE TRANSACTION. Each outstanding purchase right shall automatically be exercised, immediately prior to the effective date of any Corporate Transaction, by applying the payroll deductions of each Participant for the Purchase Interval in which such Corporate Transaction occurs to the purchase of whole shares of Common Stock at a purchase price per share equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per share of Common Stock on the Participant's Entry Date into the offering period in which such Corporate Transaction occurs or (ii) the Fair Market Value per share of Common Stock immediately prior to the effective date of such Corporate Transaction. However, the applicable limitation on the number of shares of Common Stock purchasable per Participant shall continue to apply to any such purchase. The Corporation shall use its best efforts to provide at least ten (10)-days prior written notice of the occurrence of any Corporate Transaction, and Participants shall, following the receipt of such notice, have the right to terminate their outstanding purchase rights prior to the effective date of the Corporate Transaction. H. PRORATION OF PURCHASE RIGHTS. Should the total number of shares of Common Stock to be purchased pursuant to outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the payroll deductions of each Participant, to the extent in excess of the aggregate purchase price payable for the Common Stock pro-rated to such individual, shall be refunded. I. ASSIGNABILITY. The purchase right shall be exercisable only by the Participant and shall not be assignable or transferable by the Participant. J. STOCKHOLDER RIGHTS. A Participant shall have no stockholder rights with respect to the shares subject to his or her outstanding purchase right until the shares are purchased on the Participant's behalf in accordance with the provisions of the Plan and the Participant has become a holder of record of the purchased shares. VIII. ACCRUAL LIMITATIONS A. No Participant shall be entitled to accrue rights to acquire Common Stock pursuant to any purchase right outstanding under this Plan if and to the extent such 6. 7 accrual, when aggregated with (i) rights to purchase Common Stock accrued under any other purchase right granted under this Plan and (ii) similar rights accrued under other employee stock purchase plans (within the meaning of Code Section 423) of the Corporation or any Corporate Affiliate, would otherwise permit such Participant to purchase more than TwentyFive Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate Affiliate (determined on the basis of the Fair Market Value per share on the date or dates such rights are granted) for each calendar year such rights are at any time outstanding. B. For purposes of applying such accrual limitations to the purchase rights granted under the Plan, the following provisions shall be in effect: (i) The right to acquire Common Stock under each outstanding purchase right shall accrue in a series of installments on each successive Purchase Date during the offering period on which such right remains outstanding. (ii) No right to acquire Common Stock under any outstanding purchase right shall accrue to the extent the Participant has already accrued in the same calendar year the right to acquire Common Stock under one (1) or more other purchase rights at a rate equal to Twenty-Five Thousand Dollars ($25,000) worth of Common Stock (determined on the basis of the Fair Market Value per share on the date or dates of grant) for each calendar year such rights were at any time outstanding. C. If by reason of such accrual limitations, any purchase right of a Participant does not accrue for a particular Purchase Interval, then the payroll deductions which the Participant made during that Purchase Interval with respect to such purchase right shall be promptly refunded. D. In the event there is any conflict between the provisions of this Article and one or more provisions of the Plan or any instrument issued thereunder, the provisions of this Article shall be controlling. IX. EFFECTIVE DATE AND TERM OF THE PLAN A. The Plan was adopted by the Board on July 17, 1996 and shall become effective at the Effective Time, provided no purchase rights granted under the Plan shall be exercised, and no shares of Common Stock shall be issued hereunder, until (i) the Plan shall have been approved by the stockholders of the Corporation and (ii) the Corporation shall have complied with all applicable requirements of the 1933 Act (including the registration of the shares of Common Stock issuable under the Plan on a Form S-8 registration statement filed with the Securities and Exchange Commission), all applicable listing requirements of any stock exchange (or the Nasdaq National Market, if applicable) on which the Common Stock is listed for trading and all other applicable requirements established 7. 8 by law or regulation. In the event such stockholder approval is not obtained, or such compliance is not effected, within twelve (12) months after the date on which the Plan is adopted by the Board, the Plan shall terminate and have no further force or effect, and all sums collected from Participants during the initial offering period hereunder shall be refunded. B. Unless sooner terminated by the Board, the Plan shall terminate upon the earliest of (i) the last business day in August 2006, (ii) the date on which all shares available for issuance under the Plan shall have been sold pursuant to purchase rights exercised under the Plan or (iii) the date on which all purchase rights are exercised in connection with a Corporate Transaction.

AMENDMENT OF THE PLAN The Board may alter, amend, suspend or discontinue the Plan at any time to become effective immediately following the close of any Purchase Interval. However, the Board may not, without the approval of the Corporation's stockholders, (i) materially increase the number of shares of Common Stock issuable under the Plan or the maximum number of shares purchasable per Participant on any one Purchase Date, except for permissible adjustments in the event of certain changes in the Corporation's capitalization, (ii) alter the purchase price formula so as to reduce the purchase price payable for the shares of Common Stock purchasable under the Plan or (iii) materially increase the benefits accruing to Participants under the Plan or materially modify the requirements for eligibility to participate in the Plan. XI. GENERAL PROVISIONS A. All costs and expenses incurred in the administration of the Plan shall be paid by the Corporation. B. Nothing in the Plan shall confer upon the Participant any right to continue in the employ of the Corporation or any Corporate Affiliate for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Corporation (or any Corporate Affiliate employing such person) or of the Participant, which rights are hereby expressly reserved by each, to terminate such person's employment at any time for any reason, with or without cause.

EX-99.20 23 STOCK PURCHASE AGREEMENT 1 Exhibit 99.20 CALPINE CORPORATION STOCK PURCHASE AGREEMENT I hereby elect to participate in the Employee Stock Purchase Plan (the "ESPP") effective with the Entry Date specified below, and I hereby subscribe to purchase shares of Common Stock of Calpine Corporation (the "Corporation") in accordance with the provisions of this Agreement and the ESPP. I hereby authorize payroll deductions from each of my paychecks following my entry into the ESPP in the 1% multiple of my earnings (not to exceed a maximum of 15%) specified in my attached Enrollment Form. Each offering period is divided into a series of successive purchase intervals. The initial purchase interval is to begin at the time of the initial public offering of the Common Stock and end on February 28, 1997. Subsequent purchase intervals will each be of six (6) months duration and will run from the first business day of March to the last business day of August each year and from the first business day of September each year until the last business of February in the following year. My participation will automatically remain in effect from one offering period to the next in accordance with this Agreement and my payroll deduction authorization, unless I withdraw from the ESPP or change the rate of my payroll deduction or unless my employment status changes. I may reduce the rate of my payroll deductions on one occasion per purchase interval, and I may increase my rate of payroll deduction to become effective at the beginning of any subsequent purchase interval within the offering period. My payroll deductions will be accumulated for the purchase of shares of the Corporation's Common Stock on the last business day of each purchase interval within the offering period. The purchase price per share shall be equal to 85% of the lower of (i) the fair market value per share of Common Stock on my entry date into the offering period or (ii) the fair market value per share on the semi-annual purchase date. I will also be subject to ESPP restrictions (i) limiting the maximum number of shares which I may purchase on any one purchase date to 300 shares and (ii) prohibiting me from purchasing more than $25,000 worth of Common Stock for each calendar year my purchase right remains outstanding. I may withdraw from the ESPP at any time prior to the last business day of a purchase interval and elect either to have the Corporation refund all my payroll deductions for that purchase interval or to have those payroll deductions applied to the purchase of shares of the Corporation's Common Stock at the end of such interval. However, I may not rejoin that particular offering period at any later date. Upon the termination of my employment for any reason, including death or disability, or my loss of eligible employee status, my participation in the ESPP will immediately cease and all my payroll deductions for the purchase interval in which my employment terminates or my loss of eligibility occurs will automatically be refunded. If I take an unpaid leave of absence, my payroll deductions will immediately cease, and any payroll deductions for the purchase interval in which my leave begins will, at my election, either be refunded or applied to the purchase of shares of Common Stock at the end of that purchase interval. Upon my return to active service, my payroll deductions will automatically resume at the rate in effect when my leave began. A stock certificate for the shares purchased on my behalf at the end of each purchase interval will automatically be deposited into a brokerage account which the Corporation will open on my behalf. I will notify the Corporation of any sale or disposition of my ESPP shares, and I will satisfy all applicable income and employment tax withholding requirements at the time of such sale or disposition. The Corporation has the right, exercisable in its sole discretion, to amend or terminate the ESPP at any time, with such amendment or termination to become effective immediately following the exercise of outstanding purchase rights at the end of any current purchase interval. Should the Corporation elect to terminate the ESPP, I will have no further rights to purchase shares of Common Stock pursuant to this Agreement. I have received a copy of the official Plan Prospectus summarizing the major features of the ESPP. I have read this Agreement and the Prospectus and hereby agree to be bound by the terms of both this Agreement and the ESPP. The effectiveness of this Agreement is dependent upon my eligibility to participate in the ESPP.
