This Separation Agreement (the “Agreement”) by and between Ms. Marcee Maroney (“Executive”) and KalVista Pharmaceuticals, Inc., formerly known as Carbylan Therapeutics, Inc., (the “Company”) is made effective eight (8) days after Executive’s signature hereto (the “Effective Date”), unless Executive revokes his or her acceptance of this Agreement as provided in Section 5(c) below.  Any reference to the Company throughout this Agreement shall include the Company, its subsidiaries and any successors thereto.

A.The Company anticipates closing those certain transactions (the “Transactions”) with KalVista Pharmaceuticals Ltd. (“KalVista”) contemplated by that certain Share Purchase Agreement (the “Share Purchase Agreement”) dated as of June 15, 2016, by and between the Company, KalVista, the shareholders of KalVista and, solely for the purposes of being bound by certain provisions therein and solely in such person’s capacity as the Seller Representative, Andrew Crockett.

B.Executive’s employment with the Company and status as an officer, director and employee of the Company and each of its affiliates will end effective upon the Termination Date (as defined below).

C.Executive and the Company want to end their relationship amicably and also to establish the obligations of the parties including, without limitation, all amounts due and owing to Executive.

D.The payments and benefits being made available to Executive pursuant to this Agreement are intended to satisfy all outstanding obligations under that certain employment letter agreement by between Executive and the Company, dated as of July 21, 2014 (the “Employment Agreement”).

NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties agree as follows:

1.Termination Date.  Executive acknowledges and agrees that Executive’s status as an officer, director and employee of the Company and as an officer and/or director of the Company’s subsidiaries will end effective as of the close of business on the closing of the Transactions (the “Termination Date”).  Executive hereby agrees to execute such further document(s) as shall be determined by the Company as necessary or desirable to give effect to the termination of Executive’s status as an officer and, if applicable, director of the Company and each of its subsidiaries; provided that such documents shall not be inconsistent with any of the terms of this Agreement.  If the Transactions do not close and the Share Purchase Agreement is terminated, this Agreement will be null and void, and Executive’s relationship with the Company will continue under those agreements that pre-date this Agreement as if this Agreement has never existed.

2.Final Paycheck; Payment of Accrued Wages and Expenses.

(a)Final Paycheck.  As required by law, the Company will pay Executive all accrued but unpaid base salary and all accrued and unused vacation earned through the Termination Date, subject to standard payroll deductions and withholdings.  Executive is entitled to these payments regardless of whether Executive executes this Agreement.

(b)Business Expenses.  Executive agrees that Executive has submitted Executive’s final documented expense reimbursement statement reflecting all business expenses Executive incurred through the Termination Date, if any, for which Executive seeks reimbursement.  The Company will reimburse Executive for these expenses, if any, pursuant to its regular business practice.

(c)Equity Awards: Pursuant to, and subject to the terms and conditions of, the Share Purchase Agreement, the vesting of each option to purchase Company common stock held by Executive shall accelerate in full as of immediately prior to the closing of the Transactions, and at the time of closing (i) if the option(s) is “in-the-money”, it will be net exercised such that Executive will automatically receive Company common stock (subject to an offset for withholding obligations) and (ii) if the option(s) is not “in-the-money” it will be terminated for no consideration.  An option will be considered “in-the-money” if it has an exercise price per share less than the volume weighted average closing trading price of a share of Company common stock on The NASDAQ Global Market for the ten trading days ending the trading day immediately prior to the date upon which the Transaction becomes effective.

3.Separation Payments and Benefits.  Without admission of any liability, fact or claim, the Company hereby agrees, subject to Executive’s execution and non-revocation of this Agreement and Executive’s performance of his or her continuing obligations pursuant to this Agreement, the Employment Agreement and that certain Confidential Information and Invention Assignment Agreement entered into between Executive and the Company (the “Confidentiality Agreement”), to provide Executive the severance benefits set forth below.  Specifically, the Company and Executive agree as follows:

(a)Severance.  The Company shall continue to pay to Executive his or her base salary at the rate in effect as of immediately prior to the Termination Date for the period of time commencing on the Termination Date and ending on the six (6)-month anniversary of the Termination Date (such period, the “Severance Period” and such payments, the “Cash Severance”).  Such Cash Severance payments shall be made in accordance with the Company’s standard payroll practices, less applicable withholdings and deductions, with each payment deemed to be a separate payment for purposes of Section 409A of the Code.  The first such Cash Severance payment shall commence on the first payroll date following the Effective Date, which shall include amounts otherwise due and payable under this Section 3(a) on or before such date.  In the event of Executive’s death during the Severance Period, the remaining Cash Severance shall be paid to Executive’s estate.

(b)Retention Bonus.  The Company will pay to Executive $100,003, less applicable withholdings and deductions, which represents the cash bonus Executive is entitled to under the Company’s 2016 Retention Bonus Plan.  Such retention bonus shall be paid to Executive on the first payroll date following the Effective Date.

(c)Healthcare Continuation Coverage.  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 end of the Severance Period or (ii) the date Executive and Executive’s covered dependents, if any, become eligible for healthcare coverage under another employer’s plan(s); provided that, if the Company determines that it cannot provide such continued health benefits without potentially violating applicable law or incurring additional expense for non-compliance under applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will provide to Employee in lieu thereof a lump-sum payment in an amount equal to the then-remaining premiums for the remainder of the Severance Period of such continued health benefits, which payment will be made regardless of whether Employee elects COBRA continuation coverage.  After the Company ceases to pay premiums pursuant to the preceding sentence, Executive may, if eligible, elect to continue healthcare coverage at Executive’s expense in accordance with the provisions of COBRA.  Executive acknowledges that Executive shall be solely responsible for all matters relating to Executive’s continuation of coverage pursuant to COBRA, including, without limitation, Executive’s election of such coverage and Executive’s timely payment of premiums.

(d)Taxes.  Executive understands and agrees that all payments under this Section 3 will be subject to appropriate tax withholding and other deductions.  To the extent any taxes may be payable by Executive for the benefits provided to Executive by this Section 3 beyond those withheld by the Company, Executive agrees to pay them himself or herself and to indemnify and hold the Company and the other entities released herein harmless for any tax claims or penalties, and associated attorneys’ fees and costs, resulting from any failure by him or her to make required payments.  To the extent that any reimbursements payable pursuant to this Agreement are subject to the provisions of Section 409A of the Code, such reimbursements 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.

(e)SEC Reporting.  Executive acknowledges that to the extent required by the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Executive will have continuing obligations under Section 16(a) and 16(b) of the Exchange Act to report his or her transactions in Company common stock for six (6) months following the Termination Date.  Executive hereby agrees not to undertake, directly or indirectly, any reportable transactions which include, but are not limited to,

buying, selling or otherwise disposing of any common stock of the Company held by Executive until the end of such six (6) month period.

(f)Sole Separation Benefit.  Executive agrees that the payments provided by this Section 3 are not required under the Company’s normal policies and procedures and are provided as a severance solely in connection with this Agreement and the Employment Agreement.  Thus, for any Company sponsored employee benefits not referenced in this Agreement, Executive will be treated as a terminated employee effective on the Termination Date.  This includes but is not limited to the Company’s 40l(k) plan and Company sponsored life insurance and long-term disability insurance.  Executive acknowledges and agrees that the payments referenced in this Section 3 constitute adequate and valuable consideration, in and of themselves, for the promises contained in this Agreement.

4.Full Payment.  Executive acknowledges that the payment and arrangements herein shall constitute full and complete satisfaction of any and all amounts properly due and owing to Executive as a result of Executive’s employment with the Company and the termination thereof.  Executive further acknowledges that, other than the Confidentiality Agreement, this Agreement shall supersede each agreement entered into between Executive and the Company regarding Executive’s employment, including, without limitation, the Employment Agreement, and each such agreement shall be deemed terminated and of no further effect as of the Termination Date.

5.Executive’s Release of the Company.  Executive understands that by agreeing to the release provided by this Section 5, Executive is agreeing not to sue, or otherwise file any claim against, the Company or any of its employees or other agents for any reason whatsoever based on anything that has occurred as of the date Executive signs this Agreement.
