Form of Change in Control Agreement

 Exhibit 10.21 
 CHANGE IN CONTROL AGREEMENT 
 This Change in Control Agreement (“Agreement”)
is made and entered into between Serena Software, Inc., a Delaware corporation (“Serena”), and                     
(“Executive”) as of                      (“Effective Date”). Terms that are not defined in the text of this Agreement are
defined in Exhibit A attached hereto. 
 1. TERM, PURPOSE, AND GOVERNING
DOCUMENTS. This Agreement shall remain in effect until the first anniversary of the Effective Date, at and after which time it will automatically renew for subsequent one-year terms unless Serena provides written notice of its
intention not to renew at least one month prior to the end of the applicable one-year term; however, Serena may not provide such notice of non-renewal for a one-year period following a Change in Control and such notice of non-renewal shall be void
ab-initio if Serena consummates a Change in Control in the six month period following the date of such notice. This Agreement shall supersede any and all written or verbal agreements related to severance benefits in the event of a Change in
Control; provided, however, that all other terms contained in Serena’s offer letter and or employment agreement with Executive (including Executive’s at-will employment relationship with Serena) and the documentation for the
Executive’s Equity Awards shall remain unchanged. If Executive is entitled to general severance benefits independent of a Change in Control pursuant to the terms of any offer letter and/or employment agreement between Serena and its affiliates
and Executive, then Executive shall not be entitled to severance benefits under this Agreement to the extent duplicative of the severance benefits provided under such offer letter and/or employment agreement. Furthermore, to the extent that any
federal, state or local laws, including, without limitation, so-called “plant closing” laws, require Serena to give advance notice or make a payment of any kind to Executive because of Executive’s involuntary termination due to a
layoff, reduction in force, plant or facility closing, sale of business, change of control, or any other similar event or reason, the benefits otherwise payable hereunder shall be reduced dollar for dollar by any such required payments made to
Executive. The benefits provided hereunder are intended to satisfy any and all statutory obligations that may arise out of Executive’s involuntary termination of employment for the foregoing reasons. 
 2. SEVERANCE BENEFITS IN THE EVENT OF A CHANGE
IN CONTROL. If Executive’s employment with Serena (or, upon a Change in Control, the successor company or its affiliates, as applicable) terminates because of a Termination Without Cause or a Resignation for
Good Reason within twelve (12) months after consummation of a Change in Control, and if Executive complies with the Restrictive Covenant set forth below, then Executive shall be entitled to receive the following severance benefits: 

(a) Salary Continuation. Executive shall continue to receive Executive’s base salary in effect on the date of Executive’s termination
of employment (the “Termination Date”) for a period of                     
(            ) months from the Termination Date. Payments will be made on Serena’s standard payroll dates and will be subject to applicable deductions, taxes and withholdings.

  

 1 

 (b) Target Bonus Consideration. Executive shall receive Target Bonus consideration based on the
Target Bonus in effect for Executive immediately prior to the Change in Control, consisting of the following: (1) a prorated portion of Executive’s Target Bonus based on the number of days that Executive has been employed by Serena (and
the successor company or its affiliate, if applicable) during the fiscal year in which the Termination Date occurs, which amount shall be paid in a lump sum within thirty (30) days following the Termination Date, whether or not the performance
goals or objectives upon which such bonus might otherwise be contingent are attained; and (2) Executive’s Target Bonus for an additional period of
                     (            ) fiscal year(s) commencing with the
fiscal year immediately following the fiscal year in which the Termination Date occurs, payable in a lump sum within forty-five (45) days following the end of the applicable fiscal year(s), whether or not the performance goals or objectives
applicable to each such Target Bonus are attained. Payments of the Target Bonus consideration will be subject to applicable deductions, taxes and withholdings. 
 (c) Benefits. To the extent provided by the federal COBRA law or, if applicable, state insurance laws, and group health insurance policies, Executive will be eligible for continuation of Executive’s group
health insurance. If Executive timely elects such continuation by completing and returning the necessary COBRA enrollment forms, Serena shall pay the premiums necessary to continue Executive’s then-current health insurance coverage (medical,
dental and vision) for Executive and Executive’s eligible dependents for a period of                     
(            ) months after the Termination Date or, if earlier, until the Executive and his dependents are covered under another employer’s health care benefit plan without
exclusion for any pre-existing medical condition. 
 (d) Equity Awards. The acceleration of vesting of any outstanding Equity Awards
in connection with a Change in Control shall be governed solely by the terms of the applicable Plan and award agreement. 
 (e)
Restrictive Covenant. The severance benefits described in this section are subject to a restrictive covenant. Specifically, in consideration of the foregoing benefits, Executive agrees to the following: (1) Executive shall execute and
deliver to Serena (or a successor company, as applicable) a general waiver and release in substantially the form attached hereto as Exhibit B, and such release must become effective in accordance with its terms; (2) during the
                     (            ) month period that Executive receives
salary continuation benefits, Executive shall be available if requested by Serena to provide consulting services to Serena (or a successor company, as applicable) during such period for not more than ten (10) hours per month, for which services
Executive shall receive no additional compensation other than the severance benefits set forth herein; (3) during the
                     (            ) month period that Executive receives
salary continuation benefits, Executive shall (i) refrain from making any adverse, derogatory or disparaging statement about Serena, its board of directors, officers, management, shareholders, practices, procedures or business operations to any
person or entity, and (ii) not directly or indirectly perform services for any entity that is a Competing Business; and (4) Executive shall continue to comply with the terms and conditions of Executive’s Agreement Regarding
Confidential Information and 

  

 2 

 
Assignment of Inventions for the period specified therein. As used herein, a “Competing Business” means any entity that develops, manufactures,
sells, licenses, installs, maintains or supports any application lifecyle management, operations process management or project and portfolio management software or services. Executive acknowledges and agrees that Executive shall have had access to
highly confidential information during Executive’s employment with Serena and that the foregoing restrictive covenant is reasonable to protect this confidential information. Should Executive elect to receive these severance benefits, Executive
also understands that Executive is voluntarily electing to adhere to the restrictive covenant. In addition to the remedies provided under Section 5 hereof, all severance benefits provided for under this Agreement will be forfeited in the event
Executive elects to accept the benefits and later challenge the restrictive covenant. Executive further acknowledges and agrees that the promises and restrictive covenants provided herein do not, and will not, prevent or restrict Executive in any
way from engaging in any lawful profession, trade, or business. 
 3. DEFERRAL OF PAYMENTS.
Notwithstanding anything herein to the contrary, (i) if at the time of Executive’s termination of employment with Serena, Executive is a “specified employee” as defined in Section 409A of the Code and the deferral of the
commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then Serena will defer the
commencement of the payment of any such payments or benefits hereunder until the date that is six months following Executive’s “separation from service” with Serena, as determined in accordance with applicable Treasury Regulations
under Section 409A of the Code (or the earliest date as is permitted under Section 409A of the Code without the imposition of any accelerated or additional tax) and (ii) if any other payments of money or other benefits due to
Executive hereunder could cause the application of an accelerated or additional tax under Section 409A of the Code, such payments or other benefits shall be deferred if deferral will avoid such acceleration or additional tax, or otherwise such
payment or other benefits shall be restructured, to the extent possible, in a manner, determined by the Board, that does not cause such an accelerated or additional tax and that preserves, to the greatest extent possible, the value of such payment
or other benefits. During any period payment or payments to the Executive are deferred pursuant to the foregoing, the Executive shall be entitled to interest on the deferred payment or payments at a per annum rate equal to the highest rate of
interest applicable to six (6)-month money market accounts offered by the following institutions: Citibank N.A., Wells Fargo Bank, N.A. or Bank of America, on the date of such “separation from service”. Upon the expiration of the
applicable deferral period, any payments which would have otherwise been made during that period (whether in a single sum or in installments) in the absence of this paragraph shall be paid to the Executive or his beneficiary in one lump sum. Any
remaining amounts shall be paid as and when they become due under this Agreement. 
  

	4.	LIMITATION ON BENEFITS. 

 (a) In the event that any payments to which Executive becomes entitled in accordance with the provisions of this Agreement would otherwise constitute a parachute payment under Code Section 280G, then such
payments will be subject to reduction to 

  

 3 

 
the extent necessary to assure that Executive receives only the greater of (i) the amount of those payments that would not constitute a parachute
payment or (ii) the amount that yields Executive the greatest after-tax amount of benefits after taking into account any excise tax imposed on the payments provided to Executive under this Agreement (or on any other benefits to which Executive
may be entitled in connection with any change in control or ownership of Serena or the subsequent termination of Executive’s employment with Serena) under Code Section 4999. Should a reduction in benefits be required to satisfy the benefit
limit of the foregoing paragraph, Executive’s severance and Target Bonus payments shall accordingly be reduced to the extent necessary to comply with such benefit limit. Should such benefit limit still be exceeded following such reduction, then
the number of shares that would otherwise be purchasable under the vesting-accelerated portion of each of Executive’s Equity Awards (based on the amount of the parachute payment attributable to such Equity Awards under Code Section 280G)
shall be reduced to the extent necessary to eliminate such excess, with such acceleration of vesting being cancelled in the reverse order of the date of grant of the stock awards unless Executive elects in writing a different order of cancellation.
The accounting firm engaged by Serena for general audit purposes as of the day prior to the effective date of the Change in Control shall be retained by Serena to perform the foregoing calculations at Serena’s expense. 
 (b) Executive shall not be entitled to the further severance payments or benefits described herein in the event that Executive is rehired by
Serena or an affiliate of Serena prior to the date that all payments or benefits due hereunder have been paid or provided to Executive. 
 (c) In the event that Executive is indebted to Serena or its affiliates at the time of termination of employment, Serena reserves the right to offset any severance payment or benefits described in Section 2 hereof by the amount
of such indebtedness. 
 (d) Executive shall not be eligible to receive benefits hereunder other than in connection with the first
Change in Control transaction affecting Serena during the term of this Agreement. . 
 5. REMEDIES IN THE
EVENT OF EXECUTIVE’S BREACH. Executive acknowledges and agrees that any breach of Executive’s obligations hereunder shall
constitute a material breach of this Agreement and shall, in addition to any other remedies available in law or equity, allow Serena to cease performing its obligations hereunder, including its obligations to provide any of the benefits set forth in
Section 2 hereof. 
 6. SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall inure to the
benefit of, and shall be binding upon, (i) Serena and its successors and assigns, including any successor company by merger, consolidation or transfer of all or substantially all of Serena’s assets (whether or not such transaction
constitutes a Change in Control), and (ii) the Executive, the personal representative of Executive’s estate and Executive’s heirs and legatees. 
 7. NOTICES. Any and all notices, demands or other communications required or 

  

 4 

 
desired to be given hereunder by any party shall be in writing and shall be validly given or made to another party if delivered either personally or if
deposited in the United States mail, certified or registered, postage prepaid, return receipt requested. 
 8. GOVERNING
DOCUMENTS. This Agreement, and its Exhibits, together with (i) the award agreements evidencing Executive’s currently outstanding Equity Awards and any future Equity Awards made to Executive under a Plan, and
(ii) Executive’s current or subsequent Confidentiality and Intellectual Property Agreement, shall constitute the entire agreement and understanding of Serena and its affiliates and Executive with respect to the payment of benefits in the
event of a Change in Control and shall supersede all prior and contemporaneous written or verbal agreements and understandings between Executive and Serena and its affiliates relating to such subject matter. In the event of any conflict between this
Agreement and any of the aforementioned agreements, this Agreement shall govern. 
 9. AMENDMENT. This Agreement only may be amended by
written instrument signed by Executive and an authorized executive officer of Serena.  
 10. GOVERNING
LAW. The provisions of this Agreement shall be construed and interpreted under the laws of the state that is Executive’s principal place of employment at the time of Executive’s termination of employment
with Serena. 
 11. SEVERABILITY. If an arbitrator or court of competent jurisdiction determines that any term or provision of this
Agreement is invalid or unenforceable, in whole or in part, then the remaining terms and provisions hereof shall be unimpaired. Such arbitrator or court will have the authority to modify or replace the invalid or unenforceable term or provision with
a valid and enforceable term or provision that most accurately embodies the parties’ intention with respect to the invalid or unenforceable term or provision or, if such provision cannot be so amended without materially altering the intention
of the parties, then such provision will be stricken, and the remainder of this Agreement shall continue in full force and effect. The invalidity of any provision of this Agreement shall in no way affect (to the maximum extent permissible by law)
the application of such provision under circumstances different from those adjudicated by the arbitrator or court, the application of any other provision of this Agreement, or the enforceability or invalidity of this Agreement as a whole.

 12. DISPUTE RESOLUTION. Executive and Serena agree that any dispute arising out of or relating to this Agreement will
be resolved, to the fullest extent permitted by law, by final, binding and confidential arbitration in San Francisco, California conducted by Judicial Arbitration and Mediation Services (“JAMS”) under its then-existing rules and
procedures. Executive acknowledges that by agreeing to this arbitration procedure, both Executive and Serena waive the right to resolve any such dispute through a trial by jury or judge or by administrative proceeding. In addition to and
notwithstanding those rules, Executive and Serena agree that the arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and
(b) issue a written arbitration decision including the arbitrator’s essential findings and conclusions and a statement of 

  

 5 

 
the award. Serena shall pay all of the JAMS arbitration fees in excess of those administrative fees Executive would be required to pay if the dispute were
decided in a court of law. Nothing in this Agreement is intended to prevent either Executive or Serena from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. 
 IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
