Form of Executive Change of Control and Severance Agreement



 Exhibit 10.11 
 HYPERION THERAPEUTICS, INC. 
 EXECUTIVE CHANGE OF CONTROL AND SEVERANCE
AGREEMENT 
 This Change of Control and Severance Agreement (the “Agreement”) is made and entered into by
and between                      (the “Executive”) and Hyperion Therapeutics, Inc. (the “Company”), effective as of
the latest date set forth by the signatures of the parties hereto below (the “Effective Date”). 
 R E C I T
A L S 
 A. It is expected that the Company from time to time will consider the possibility of an acquisition by another
company or other change of control. The Board of Directors of the Company (the “Board”) recognizes that such consideration as well as the possibility of an involuntary termination or reduction in responsibility can be a distraction
to Executive and can cause Executive to consider alternative employment opportunities. The Board has determined that it is in the best interests of the Company and its stockholders to ensure that the Company will have the continued dedication and
objectivity of Executive, notwithstanding the possibility, threat or occurrence of such an event. 
 B. The Board believes that
it is in the best interests of the Company and its stockholders to provide Executive with an incentive to continue Executive’s employment and to motivate Executive to maximize the value of the Company upon a Change of Control (as defined below)
for the benefit of its stockholders. 
 C. The Board believes that it is imperative to provide Executive with severance benefits
upon certain terminations of Executive’s service to the Company that enhance Executive’s financial security and provide incentive and encouragement to Executive to remain with the Company notwithstanding the possibility of such an event.

 D. Capitalized terms used in this Agreement are defined in Section 7 below. 

The parties hereto agree as follows: 
 1. Term of Agreement. This Agreement shall become effective as of the Effective Date and terminate upon the date that all obligations of the parties hereto with respect to this Agreement have been
satisfied. 
 2. At-Will Employment. The Company and Executive acknowledge that Executive’s employment is and shall
continue to be “at-will,” which means that Executive’s employment may be terminated by either Executive or the Company at any time, for any legal reason, with or without cause, and with or without advance notice. Nothing in this
Agreement is intended to create or imply a promise or contract of employment for a specified term. The at-will nature of the employment relationship will remain in effect throughout Executive’s employment with the Company, and can be modified
only by a written agreement signed by both Executive and the Chief Executive Officer of the Company. The at-will nature of Executive’s employment relationship may not be modified by any oral or implied agreement, or by any Company policies,
practices or patterns of conduct. Except as provided in this Agreement, if Executive’s employment terminates for any reason, Executive shall not be entitled to any payments, benefits, damages, awards or compensation. 







 3. Termination Not in Connection With Change of Control. If, at any time other than
during the twelve (12) month period following a Change of Control, the Company terminates Executive’s employment with the Company without Cause or if Executive resigns from employment with the Company for Good Reason, and if Executive
executes a general release of all claims against the Company and its affiliates in a form similar to that which is attached hereto as Exhibit A (a “Release of Claims”), and if all applicable revocation periods have expired
without the Release of Claims being revoked, then in addition to any accrued but unpaid salary, bonus, vacation and expense reimbursement payable in accordance with applicable law, the Company shall provide Executive with the following within sixty
(60) days of such termination: 
 (a) Severance. Executive shall be entitled to receive an
amount equal to twelve (12) months of Executive’s base salary at the rate in effect immediately prior to Executive’s termination of employment payable in substantially equal installments in accordance with the Company’s normal
payroll policies, less applicable withholdings, with such installments to commence on the first payroll period following the sixtieth (60th) day after the date of Executive’s termination of employment (with the first such installment to include any
payments that otherwise would have been made if the Release of Claims were not subject to revocation on the date of termination), provided that Executive has complied with the requirements of Section 3. 

(b) Equity Awards. Each outstanding equity award, including, without limitation, each stock option and restricted stock award,
held by Executive shall automatically become vested and, if applicable, exercisable and any forfeiture restrictions or rights of repurchase thereon shall immediately lapse, in each case, with respect to that number of shares of Company common stock
subject to such equity award that otherwise would have vested had Executive’s employment with the Company continued for twelve (12) months following the date of Executive’s termination of employment. 

(c) Continued Healthcare. If Executive elects to receive continued healthcare coverage pursuant to the provisions of the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall directly pay, or reimburse Executive for, the premium for Executive and Executive’ s covered dependents through the earlier of
(i) the eighteen (18) month anniversary of the date of Executive’s termination of employment and (ii) the date Executive and Executive’s covered dependents, if any, become eligible for healthcare coverage under another
employer’s plan(s). After the Company ceases to pay premiums pursuant to the preceding sentence, Executive may, for any remaining period of COBRA coverage, elect to continue healthcare coverage at Executive’s expense in accordance with the
provisions of COBRA. 
 (d) Annual Bonus. Executive shall be entitled to receive an amount equal to
twelve (12) months of Executive’s target annual bonus for the fiscal year in which Executive’s termination from the Company occurs. Such bonus shall be paid on the first payroll period following the sixtieth (60th) day after the date of Executive’s termination of
employment, provided Executive has complied with the requirements of Section 3. 
 (e) Transition Support. At the
election of Executive, the Company will either (i) pay Executive a lump sum amount of $15,000 to be used by Executive for outplacement assistance, tax planning, educational assistance, or similar transition support, or (ii) provide
Executive with the same or similar services through a professional outplacement firm selected by the Company. 

  
 2 








 (f) Handheld Device. Executive will be able to retain his or her blackberry,
smartphone or other handheld device purchased by the Company, including any personal calendars and personal contacts but not Company documents, data or e-mails stored thereupon, but Executive will have to pay any continued service costs related
thereto. 
 4. Termination Within 12 Months Following Change of Control. If Executive’s employment with the Company
is terminated by the Company without Cause or if Executive resigns from employment with the Company for Good Reason, in each case, within the twelve (12) month period following a Change of Control, and if Executive executes a general release of
all claims against the Company and its affiliates in a form similar to that which is attached hereto as Exhibit A, and if all applicable revocation periods have expired without the Release of Claims being revoked, within sixty (60) days
of such termination then in addition to any accrued but unpaid salary, bonus, vacation and expense reimbursement payable in accordance with applicable law, the Company shall provide Executive with the following: 

(a) Severance. Executive shall be entitled to receive an amount equal to twelve (12) months of
Executive’s base salary at the rate in effect immediately prior to Executive’s termination of employment payable in substantially equal installments in accordance with the Company’s normal payroll policies, less applicable
withholdings, with such installments to commence on the first payroll period following the sixtieth (60th) day after the date of Executive’s termination of employment (with the first such installment to include any payments that otherwise would have been made if the Release of Claims were not
subject to revocation on the date of termination), provided that Executive has complied with the requirements of Section 4. 
 (b) Equity Awards. Each outstanding equity award, including, without limitation, each stock option and restricted stock award, held by Executive shall automatically become vested and, if
applicable, exercisable and any forfeiture restrictions or rights of repurchase thereon shall immediately lapse. 
 (c)
Continued Healthcare. If Executive elects to receive continued healthcare coverage pursuant to the provisions of COBRA, the Company shall directly pay, or reimburse Executive for, the premium for Executive and Executive’ s covered
dependents through the earlier of (i) the eighteen (18) month anniversary of the date of Executive’s termination of employment and (ii) the date Executive and Executive’s covered dependents, if any, become eligible for
healthcare coverage under another employer’s plan(s). After the Company ceases to pay premiums pursuant to the preceding sentence, Executive may, for any remaining period of COBRA coverage, elect to continue healthcare coverage at
Executive’s expense in accordance with the provisions of COBRA. 
 (d) Annual Bonus. Executive
shall be entitled to receive an amount equal to twelve (12) months of Executive’s target annual bonus for the fiscal year in which Executive’s termination from the Company occurs. Such bonus shall be paid on the first payroll period
following the sixtieth (60th) day after the date of
Executive’s termination of employment, provided Executive has complied with the requirements of Section 4. 
 (e)
Transition Support. At the election of Executive, the Company will either (i) pay Executive a lump sum amount of $15,000 to be used by Executive for outplacement assistance, tax planning, educational assistance, or similar transition
support, or (ii) provide Executive with the same or similar services through a professional outplacement firm selected by the Company. 

  
 3 








 (f) Handheld Device. Executive will be able to retain his or her blackberry,
smartphone or other handheld device purchased by the Company, including any personal calendars and personal contacts but not Company documents, data or e-mails stored thereupon, but Executive will have to pay any continued service costs related
thereto. 
 5. Other Termination. If Executive’s employment with the Company is terminated by the Company for Cause
or by Executive under circumstances that do not constitute Good Reason, then Executive shall not be entitled to any benefits hereunder other than (i) payment of all accrued but unpaid salary, bonus, vacation and expense reimbursement in
accordance with applicable law and (ii) election, at Executive’s own expense, of any continued healthcare coverage as may be required under COBRA or similar state law. 

6. Limitation on Payments. In the event that the severance and other benefits provided for in this Agreement or otherwise payable
to Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and (ii) but for this Section, would be subject to the excise
tax imposed by Section 4999 of the Code, then Executive’s severance benefits under this Agreement shall be payable either 
 (a) in full, or 
 (b) as to such lesser amount which would result in no portion of
such severance benefits being subject to excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999,
results in the receipt by Executive on an after-tax basis, of the greatest amount of severance benefits under this Agreement, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code.
Unless the Company and Executive otherwise agree in writing, any determination required under this Section shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall
be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely
on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order
to make a determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section. 

7. Definition of Terms. The following terms referred to in this Agreement shall have the following meanings: 

(a) Cause. “Cause” means a reasonable determination by the Board that Executive has (i) engaged in theft,
dishonesty or falsification of any employment or Company records; (ii) maliciously or recklessly disclosed the Company’s confidential or proprietary information; (iii) committed any immoral or illegal act or any gross or willful
misconduct, which the Board reasonably determines has (A) seriously undermined the ability of the Company’s Board or management to entrust Executive with important matters or otherwise work effectively with Executive, (B) contributed
to the Company’s loss of significant revenues or business opportunities, or (C) significantly and detrimentally affected the business or reputation of the Company or any of its 

  
 4 








 
subsidiaries; and/or (iv) failed or refused to follow the reasonable and lawful directives of the Board, provided such failure or refusal continues after Executive’s receipt of
reasonable notice in writing of such failure or refusal and an opportunity to correct the problem. 
 (b) Change of
Control. “Change of Control” shall mean the occurrence of any of the following events: (i) the approval by shareholders of the Company of a merger or consolidation of the Company with any other corporation, other than a
merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity)
more than fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; (ii) the approval by the shareholders of the
Company of a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; (iii) any “person” (as such term is used in Sections 13(d)
and 14(d) of the Securities Exchange Act of 1934, as amended) becoming the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of
the total voting power represented by the Company’s then outstanding voting securities; or (iv) a change in the composition of the Board, as a result of which fewer than a majority of the directors are Incumbent Directors.
“Incumbent Directors” shall mean directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for election, to the Board with the affirmative votes of at least a majority of
those directors whose election or nomination was not in connection with any transactions described in subsections (i), (ii) or (iii) or in connection with an actual or threatened proxy contest relating to the election of directors of the
Company. 
 Notwithstanding the foregoing, a transaction shall not constitute a Change of Control if: (1) its sole purpose is to change the
state of the Company’s incorporation; (2) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction;
(3) it constitutes the initial public offering of the Company’s securities; or (4) it is a transaction effected primarily for the purpose of financing the Company with cash (as determined by the Board acting in good faith and without
regard to whether such transaction is effectuated by a merger, equity financing or otherwise). 
 (c) Good Reason.
“Good Reason” means Executive’s resignation from employment with the Company after the occurrence, without Executive’s express written consent, of any of the following: (i) a material breach by the Company of this
Agreement; (ii) a change in Executive’s position with the Company that materially reduces Executive’s level of authority, responsibilities or duties (including, without limitation, any change in Executive’s position such that
Executive is no longer employed in substantially the same position and with substantially the same level of authority, responsibilities or duties at the ultimate parent corporation in an affiliated group of companies); (iii) a reduction in
Executive’s base salary by more than ten percent (10%); or (iv) a change in Executive’s primary place of work in a manner that increases Executive’s average daily commute by at least 25 miles. Notwithstanding the foregoing,
Executive’s resignation shall not constitute a resignation for “Good Reason” unless Executive notifies the Company of the events considered to create Good Reason within ninety (90) days of the occurrence of such events and gives
the Company at least thirty (30) days to cure such events (the “Company Cure Period”). Executive’s continued employment thirty (30) days after the expiration of the Company Cure Period shall constitute
Executive’s consent to, or waiver of rights with respect to, any circumstances constituting Good Reason. Executive may, however, rely on a waived condition to demonstrate that any subsequent, separate, event or circumstance constitutes Good
Reason. For example, and 

  
 5 








 
without limitation, a reduction in Executive’s authorities that is deemed waived by operation of this clause may be considered for purposes of determining whether any subsequent reduction in
Executive’s authorities, when taken into consideration with the first reduction, constitutes a “material reduction.” Executive’s right to resign employment for Good Reason shall not be affected by Executive’s incapacity due
to physical or mental illness. 
 8. Successors. 

(a) Company’s Successors. Any successor to the Company (whether direct or indirect and whether by purchase, merger,
consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets shall assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same
manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under this Agreement, the term “Company” shall include any successor to the Company’s business
and/or assets which executes and delivers the assumption agreement described in this Section 8(a) or which becomes bound by the terms of this Agreement by operation of law. 

(b) Executive’s Successors. The terms of this Agreement and all rights of Executive hereunder shall inure to the benefit of,
and be enforceable by, Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. 
 9. Notices. Notices and all other communications contemplated by this Agreement shall be in writing and shall be deemed to have been duly given when personally delivered or one day following
mailing via Federal Express or similar overnight courier service. In the case of Executive, mailed notices shall be addressed to Executive at the home address that the Company has on file for Executive. In the case of the Company, mailed notices
shall be addressed to its corporate headquarters, and all notices shall be directed to the attention of the Company’s Chief Financial Officer. 
 10. Confidentiality. 
 (a) Confidentiality. Reference is made to the
Executive Confidential Information and Invention Assignment Agreement entered into between Executive and the Company (the “Confidential Information Agreement”). Executive shall continue to be subject to the Confidential Information
Agreement, and the confidentiality provisions of the Confidential Information Agreement shall apply to this Agreement. 
 (b)
Survival of Provisions. The provisions of this Section 10 shall survive the termination or expiration of the applicable Executive’s employment with the Company and shall be fully enforceable thereafter. If it is determined by a
court of competent jurisdiction in any state that any restriction in this Section 10 is excessive in duration or scope or is unreasonable or unenforceable under the laws of that state, it is the intention of the parties that such restriction
may be modified or amended by the court to render it enforceable to the maximum extent permitted by the law of that state. 

11. Miscellaneous Provisions. 

  
 6 








 (a) Section 409A. 

(i) Separation from Service. Notwithstanding any provision to the contrary in this Agreement, no amount
deemed deferred compensation subject to Section 409A of the Code shall be payable pursuant to Sections 3 or 4 unless Executive’s termination of employment constitutes a “separation from service” with the Company within the
meaning of Section 409A of the Code and the Department of Treasury regulations and other guidance promulgated thereunder and, except as provided under Section 11(a)(ii) of this Agreement, any such amount shall not be paid, or in the case
of installments, commence payment, until the first payroll period following the sixtieth (60th) day following Executive’s Separation from Service. Any installment payments that would have been made to Executive during the sixty (60) day period immediately following Executive’s
Separation from Service but for the preceding sentence shall be paid to Executive on the first payroll period following the sixtieth (60th) day after Executive’s Separation from Service and the remaining payments shall be made as provided in this
Agreement. 
 (ii) Specified Executive. Notwithstanding any provision to the contrary in this Agreement, if Executive is
deemed at the time of his separation from service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of any portion of the benefits to which Executive is entitled
under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of Executive’s benefits shall not be provided to Executive prior to the earlier of (a) the
expiration of the six (6)-month period measured from the date of Executive’s “separation from service” with the Company (as such term is defined in the Treasury Regulations issued under Section 409A of the Code) or (b) the
date of Executive’s death. Upon the first business day following the expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Section 11(a)(ii) shall be paid in a lump sum to Executive,
and any remaining payments due under this Agreement shall be paid as otherwise provided herein. 
 (iii) Expense
Reimbursements. To the extent that any reimbursements payable pursuant to this Agreement are subject to the provisions of Section 409A of the Code, any such reimbursements payable to Executive pursuant to this Agreement shall be paid to
Executive no later than December 31 of the year following the year in which the expense was incurred, the amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year, and
Executive’s right to reimbursement under this Agreement will not be subject to liquidation or exchange for another benefit. 
 (iv) Installments. For purposes of Section 409A of the Code (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), Executive’s right to
receive any installment payments under this Agreement shall be treated as a right to receive a series of separate payments and, accordingly, each such installment payment shall at all times be considered a separate and distinct payment. 

(b) Waiver. No provision of this Agreement shall be modified, waived or discharged unless the modification, waiver or discharge is
agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any breach of, or of compliance with, any condition or provision of this Agreement by the other party shall
be considered a waiver of any other condition or provision or of the same condition or provision at another time. 

  
 7 








 (c) Whole Agreement. This Agreement and the Confidential Information Agreement
represent the entire understanding of the parties hereto with respect to the subject matter hereof and supersede all prior arrangements and understandings regarding same including, without limitation, any severance provisions of the offer letter
agreement between Executive and the Company. 
 (d) Choice of Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the State of California. 
 (e) Severability. The
invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision hereof, which shall remain in full force and effect. 

(f) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which
together will constitute one and the same instrument.

 (ii) Other employment laws, such as the federal

the EEOC, the NLRB, the DFEH or similar state or local agencies. However, by entering into this Release, Executive understands and agrees that he is waiving any and all rights to recover any monetary relief or other personal relief as a result of
any such EEOC, NLRB, DFEH or similar state or local agency proceedings, including any subsequent legal action. 







 (d) Claims Not Released. The Released Claims do not include claims by
Executive for: (i) unemployment insurance; (ii) worker’s compensation benefits; (iii) state disability compensation; (iv) previously vested benefits under any the Company-sponsored benefits plan; and (v) any other

 (e) EXCEPT AS OUTLINED ABOVE, BY SIGNING THIS RELEASE, EXECUTIVE
WAIVES ANY RIGHT THAT HE MAY HAVE HAD TO PURSUE OR BRING A LAWSUIT OR MAKE ANY LEGAL CLAIM AGAINST THE COMPANY OR THE RELEASEES INCLUDING, BUT NOT LIMITED TO, CLAIMS THAT IN ANY WAY ARISE FROM OR RELATE TO HIS EMPLOYMENT OR THE TERMINATION OF THAT
EMPLOYMENT, UP TO AND INCLUDING THE DATE OF THE EXECUTION OF THIS RELEASE. EXECUTIVE AGREES NOT TO PURSUE OR BRING ANY SUCH LAWSUIT OR LEGAL CLAIM SEEKING MONETARY OR OTHER RELIEF. 

(f) Waiver of Rights Under California Civil Code Section 1542. Executive acknowledges that he has read Section 1542 of
the Civil Code of the State of California, which provides as follows: 
 A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH
THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR. 

Executive understands that for purposes of this Section 2(f), he is considered the “creditor” and the Company is considered the
“debtor.” Executive understands that Section 1542 gives him the right not to release existing claims of which he is not now aware, unless he voluntarily chooses to waive this right. Even though Executive is aware of this right,
Executive nevertheless hereby voluntarily waives the right described in Section 1542 with respect to the Released Claims, and elects to assume all risks for claims that now exist in his favor, known or unknown, arising from
the subject matter of the Release. 
 Executive acknowledges that different or additional facts may be discovered in addition to what he now
knows or believes to be true with respect to the matters herein released, and Executive agrees that this Release shall be and remain in effect in all respects as a complete and final release of the matters released, notwithstanding any such
different or additional facts. Executive represents and warrants that he has not previously filed or joined in any claims that are released herein and that he has not given or sold any portion of any claims released herein to anyone else.

 (g) Acknowledgments/Time Frames. 
 (i) Executive agrees and acknowledges that (A) he understands the language used in this Release and its legal effect, and (B) he will receive compensation and/or benefits under the Employment
Agreement to which Executive would not have been entitled without signing this Release. Executive further agrees and acknowledges that, with respect to the General Release in this Section 2, Executive is specifically releasing all claims and
rights under the Age Discrimination in Employment Act, as amended, 29 U.S.C. Section 621 et seq. Executive acknowledges that he has read and understands the foregoing Release and executes it voluntarily and without coercion.
