SERENA SOFTWARE, INC.

AMENDED AND RESTATED 2006 STOCK INCENTIVE PLAN

STOCK OPTION AGREEMENT

(Time Option)

Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Stock Option Agreement, Serena Software, Inc. (the “Company”) has granted you a stock option under its Amended and Restated 2006 Stock Incentive Plan (as amended from time to time, the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in your Grant Notice at the exercise price indicated in your Grant Notice. Capitalized terms not defined in this Stock Option Agreement or in the Grant Notice but defined in the Plan shall have the same definitions as in the Plan. For the avoidance of doubt, the terms and conditions of the Grant Notice are a part of the Stock Option Agreement, unless otherwise specified.

The details and terms and conditions of this Stock Option Agreement shall govern your Option, notwithstanding any less favorable terms and conditions on the same matter set forth in the Plan (subject, however, to Section 15 hereof):

1. Vesting.

(a) Subject to the limitations contained herein, your Option will vest as set forth in your Grant Notice, provided that vesting will cease upon the termination of your Continuous Service.

(b) Notwithstanding any provision of this Stock Option Agreement to the contrary, in the event of a Change in Control, the Option shall, to the extent not then vested and not previously cancelled, become fully vested and exercisable immediately prior to the consummation of such Change in Control.

2. Number of Shares and Exercise Price. The number of shares of Common Stock subject to your Option and your exercise price per share referenced in your Grant Notice may be adjusted from time to time for various adjustments in the Company’s equity capital structure, as provided in the Plan.

3. Method of Payment.

(a) Payment of the exercise price is due in full upon exercise of all or any part of your Option. You may elect to make payment of the exercise price in cash or by check. Alternatively, provided that at the time of exercise there is a public market for the shares of Common Stock, your exercise may be implemented pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. Notwithstanding the terms of the previous sentence, you may not be permitted to exercise your Option pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board if such exercise would violate the provisions of Section 402 of the Sarbanes-Oxley Act of 2002.

3

(b) You may elect to make payment of the exercise price, in whole or in part, in shares of Common Stock having a Fair Market Value equal to the amount of the aggregate exercise price or such portion thereof, as applicable; provided, however, that you must satisfy all such requirements as may be imposed by the Board including without limitation that you have held such shares for not less than six months (or such other period as established from time to time by the Board in order to avoid a supplemental charge to earnings for financial accounting purposes).

(c) Where you elect to pay the exercise price of an Option and/or taxes relating to the exercise of an Option by delivering shares of Common Stock, you may, subject to procedures satisfactory to the Board, satisfy such delivery requirement by presenting proof that you are the Beneficial Owner of such shares of Common Stock, in which case the Company shall treat the Option as exercised without further payment and shall withhold such number of shares from the Shares acquired by the exercise of the Option.

(d) The Company may permit you to make payment of the exercise price in any other form of legal consideration that may be acceptable to the Board in its sole discretion.

4. Whole Shares. You may exercise your Option only for whole shares of Common Stock.

5. Compliance.

(a) Securities Law Compliance. Notwithstanding anything to the contrary contained herein, you may not exercise your Option unless the Shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such Shares are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your Option must also comply with other applicable laws and regulations governing your Option, and you may not exercise your Option if the Company determines that such exercise would not be in material compliance with such laws and regulations.

(b) Plan Compliance. Notwithstanding anything to the contrary contained herein, you may not exercise your Option if the terms of the Plan do not permit the exercise of Options, or if the Company exercises its rights under the Plan to suspend, delay or restrict the exercise of Options.

6. Term. You may not exercise your Option before the commencement of its term on the Date of Grant or after its term expires. Subject to the provisions of the Plan and this Stock Option Agreement, you may exercise all or any part of the vested portion of the Option at any time prior to the earliest to occur of:

(a) the date on which your Continuous Service is terminated for Cause;

(b) three (3) months after you terminate your Continuous Service by resigning without Good Reason;

(c) twelve (12) months after the termination of your Continuous Service without Cause or after you terminate your Continuous Service by resigning for Good Reason;

4

(d) twelve (12) months after the termination of your Continuous Service due to your Disability;

(e) twelve (12) months after the termination of your Continuous Service due to your death; or

(f) the Expiration Date indicated in the Grant Notice.

Notwithstanding the foregoing, if the exercise of your Option is prevented within the applicable time periods set forth in Sections 6(b), (c) or (d) for any reason, your Option shall not expire before the date that is thirty (30) days after the date that you are notified by the Company that the Option is again exercisable, but in any event no later than the Expiration Date indicated in your Grant Notice.

7. Exercise Procedures.

(a) Subject to Section 5 above and other relevant terms and conditions of the Plan and this Stock Option Agreement, you may exercise the vested portion of your Option during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Company’s Chief Financial Officer, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then reasonably require.

(b) By exercising your Option you agree that, as a condition to any exercise of your Option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company (including any Affiliate) arising by reason of (i) the exercise of your Option, or (ii) other applicable events.

(c) By exercising your Option you agree that, as a condition to any exercise of your Option, you and your spouse, if requested by the Company, contemporaneously with the exercise of your Option and prior to the issuance of any certificate representing the Shares of Common Stock purchased upon the exercise of your Option, shall execute the Management Stockholders Agreement, including any and all amendments to such agreement in effect at the time of such exercise.

(d) By exercising your Option you agree that the Company (or a representative of the underwriter(s)) may, in connection with the first underwritten registration of the offering of any equity securities of the Company under the Securities Act (or any underwritten registration of any securities of the Company prior to that time), require that for a specified period of time, you not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by you. You further agree to execute and deliver such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop transfer instructions with respect to your shares of Common Stock until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 7(d) and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.

5

(e) As a condition of any exercise of your Option, you and your spouse, if any, agree that prior to the effectiveness of the first underwritten registration of the Company’s equity securities under the Securities Act, you shall not transfer any or all of the shares of Common Stock purchased upon exercise of your Option unless permitted to do so under the terms of the Plan or the Management Stockholders Agreement.

8. Documents Governing Issued Common Stock. Shares of Common Stock that you acquire upon exercise of your Option are subject to the terms of the Plan, the Company’s bylaws, the Company’s certificate of incorporation, any agreement relating to such shares of Common Stock to which you become a party, or any other similar document. You should ensure that you understand your rights and obligations as a stockholder of the Company prior to the time that you exercise your Option.

9. Limitations on Transfer of Options. Your Option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your Option.

10. Rights Upon Exercise. You will not have any rights to dividends or other rights of a stockholder with respect to the Shares subject to the Option until you have given written notice of the exercise of the Option, paid in full for such Shares and, if applicable, satisfied any other conditions imposed by the Board pursuant to the Plan.

11. Option Not a Service Contract. Your Option is not an employment contract, and nothing in your Option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ or service of the Company or any of its Affiliates, or of the Company or any of its Affiliates to continue your employment. In addition, nothing in your Option shall obligate the Company or any of its Affiliates, their respective stockholders, Boards of Directors, officers or employees to continue any relationship that you might have as a Director or Consultant or otherwise for the Company or any of its Affiliates.

12. Withholding Obligations and Notice Requirement.

(a) At the time you exercise your Option, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “same day sale” program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company and applicable law, including, but not limited to, Section 402 of the Sarbanes-Oxley Act of 2002) any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any of its Affiliates, which arise in connection with your Option.

(b) You may not exercise your Option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied or appropriate arrangements (acceptable to the Company) are made therefor.

13. Notices. Any notices provided for in your Option or the Plan shall be given in writing and shall be deemed effectively given upon receipt, or in the case of notices delivered by mail to you, five (5) days after deposit in the United States mail (or with another delivery service), certified or registered mail, return receipt requested, postage prepaid, addressed to you at the last address you provided to the Company.

6

14. Signature in Counterparts. This Stock Option Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

15. Option Subject to Plan Document. By entering into this Stock Option Agreement, you agree and acknowledge that you have received and read a copy of the Plan and Management Stockholders Agreement. The Option is subject to the terms and provisions of the Plan and the Management Stockholders Agreement and such terms and provisions are hereby incorporated herein by reference. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan or the Management Stockholders Agreement, the applicable terms and provisions of the Plan or Management Stockholders Agreement, as applicable, will govern and prevail. In the event of a conflict between any term or provision of the Plan and any term or provision of the Management Stockholders Agreement, the applicable terms and provisions of the Management Stockholders Agreement will govern and prevail.

NOTICE OF EXERCISE

Ladies and Gentlemen:

This constitutes notice under my stock option that I, as Optionee, elect to purchase the number of Shares for the price set forth below.

By this exercise, I agree (i) to execute or provide such additional documents as Serena Software, Inc. (the “Company”) may reasonably require pursuant to the terms of this Notice of Exercise and the Company’s 2006 Stock Incentive Plan (the “Plan”), and (ii) to provide for the payment by me to the Company (in the manner designated by the Company) of the Company’s withholding obligation, if any, relating to the exercise of this Option.

I hereby make the following certifications and representations with respect to the number of shares of Common Stock of the Company listed above (the “Shares”):

I am aware that my investment in the Company is a speculative investment that has limited liquidity and is subject to the risk of complete loss. I am able, without impairing my financial condition, to hold the Shares for an indefinite period and to suffer a complete loss of my investment in the Shares.

I represent and warrant to the Company that I am acquiring and will hold the Shares for investment for my account only, and not with a view to, or for resale in connection with, any “distribution” of the Shares within the meaning of the Securities Act of 1933 (the “Securities Act”) or the similar laws of any state or foreign jurisdiction.

I understand that the Shares have not been registered under the Securities Act, the Securities Exchange Act of 1934, or under the similar laws of any state or foreign jurisdiction (collectively, “Applicable Securities Laws”) by reason of a specific exemption therefrom and that the Shares must be held indefinitely, unless they are subsequently registered under the Applicable Securities Laws or I obtain an opinion of counsel (in form and substance satisfactory to the Company and its counsel) that registration is not required.

I acknowledge that the Company is under no obligation to register the Shares under Applicable Securities Laws.

I am aware of the adoption of Rule 144 by the Securities and Exchange Commission under the Securities Act, which permits limited public resales of securities acquired in a non-public offering, subject to the satisfaction of certain conditions. These conditions may include (without limitation) that certain current public information about the issuer is available, that the resale occurs only after the holding period required by Rule 144 has been satisfied, that the sale occurs through an unsolicited “broker’s transaction” and that the amount of securities being sold during any three-month period does not exceed specified limitations. I understand that the conditions for resale set forth in Rule 144 have not been satisfied and that the Company has no plans to satisfy these conditions in the foreseeable future.

I will not sell, transfer or otherwise dispose of the Shares in violation of the Plan, the agreement under which my right to acquire the Shares was granted, Applicable Securities Laws, or the rules promulgated thereunder, including Rule 144 under the Securities Act.

I acknowledge that I have received and had access to such information as I consider necessary or appropriate for deciding whether to invest in the Shares and that I had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the issuance of the Shares. I specifically acknowledge that I have reviewed or had the opportunity to review (i) the Plan, (ii) a summary of the Plan, and (iii) financial information and risk factors related to the Company and an investment in the Shares, including, without limitation, the Company’s most recent annual, quarterly and current reports, which are available from the Securities and Exchange Commission’s website at www.sec.gov.

I acknowledge that the Shares will be subject to certain encumbrances, including, but not limited to, drag along rights in favor of certain stockholders of the Company, repurchase rights in favor of the Company, limitations on transfer, and other encumbrances set forth in the Plan, Stock Option Agreement, Management Stockholders Agreement and other applicable agreements and/or described in the Company’s bylaws or certificate of incorporation in effect at such time as the Company or such other person elects to exercise its or his right.

I acknowledge that I am acquiring the Shares subject to all other terms of the Plan, the Stock Option Grant Notice, the Stock Option Agreement and the Management Stockholders Agreement.

I further agree that if required by the Company (or a representative of the underwriter(s)) in connection with the first underwritten registration of the offering of any equity securities of the Company under the Securities Act (or any underwritten registration of any securities of the Company prior to that time), for a specified period of time, I will not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Shares or other securities of the Company held by me. I further agree to execute and deliver such other agreements as may be

2

reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop transfer instructions with respect to my Shares until the end of such period.

I agree, and as a condition of exercise if I am married I will obtain the agreement of my spouse, that prior to the effectiveness of the first underwritten registration of the Company’s equity securities under the Securities Act, I will not transfer any or all of the Shares unless pursuant to an exception provided in the Plan or the Stock Option Agreement.

I agree that as a condition to this exercise, the certificates evidencing the Shares shall remain in the physical custody of the Company or its designee at all times prior to the last to occur of (i) the date on which all contractual restrictions set forth in the Plan, the Company’s Articles of Incorporation and/or bylaws, or in the documents evidencing the Stock Option Agreement lapse, or (ii) the date on which all contractual requirements set forth in the Plan, the Company’s Articles of Incorporation and/or bylaws, or in the documents evidencing the Stock Option Agreement are satisfied. As a condition to this exercise I agree to execute three (3) copies of the Assignment Separate From Certificate (with date and number of Shares blank) substantially in the form attached to this Notice of Exercise as Attachment A, and two (2) copies of the Joint Escrow Instructions substantially in the form attached to this Notice of Exercise as Attachment B, and to deliver the same to the Company, along with such additional documents as the Company may require.

I further acknowledge that all certificates representing any of the Shares subject to the provisions of my Option shall have endorsed thereon appropriate legends reflecting the foregoing limitations, as well as any legends reflecting restrictions pursuant to the Company’s Certificate of Incorporation, by-laws, and/or Applicable Securities Laws.

3

I agree to seek the consent of my spouse to the extent required by the Company to enforce the foregoing.

SPOUSAL CONSENT (if applicable):

The undersigned spouse of Optionee has read and hereby approves the terms and conditions of this Notice of Exercise. In consideration of the Company issuing his or her spouse the Shares, the undersigned hereby agrees to be irrevocably bound by the terms and conditions of the Plan, Management Stockholders Agreement and Joint Escrow Instructions (if applicable) and, if the undersigned resides in a community property state, further agrees that any community property interest shall be similarly bound.
