transition of his responsibilities, litigation or proceedings related to his work period with that employer, or other similar matters. Executive also agrees that he shall not take personal advantage of any business opportunities which arise during

Agreement and with due regard for his position, Executive shall be subject to the Bylaws, policies, practices, procedures and rules of the Company, including those policies and procedures explained in the Company’s Employee Handbook, but in no
event shall anything in such documents expand the definition of a “Cause” termination hereunder. Notwithstanding the foregoing, the Board shall amend the Bylaws as soon as practicable following the execution of this Agreement so that
roles, responsibilities, authority, and reporting lines of the Executive Vice President and Chief Administrative and Legal Officer as described therein are consistent with the terms of this Agreement.

payment such that after the payment of all taxes on the commuting expenses and the additional payment Executive retains the amount of the commuting expenses. During the Term, the Company will also provide up to $65,000 to be applied to the cost of a

on the Company’s regularly-scheduled paydays as it is earned. Executive’s Salary will be reviewed at least annually by the Board following the first anniversary date of the Effective Date and may be adjusted upward (in which case such

Bonus”); provided, however, that the failure of the Board to award any such bonus shall not give rise to any claim against the Company. The timing of the payment of any Discretionary Cash Bonus shall be determined in the
Board’s sole discretion; however, in no event will any Discretionary Cash Bonus be paid later than March 15 following the year in which it vests.

 8. Other Tax Matters. 

8.1 The Company shall withhold all applicable federal, state and local taxes, social security and workers’
compensation contributions and other amounts as may be required by law with respect to compensation payable to Executive pursuant to this Agreement. 

8.2 Notwithstanding anything herein to the contrary, this Agreement is intended to be interpreted and applied so that
the payment of the benefits set forth herein either shall either be exempt from the requirements of Section 409A of the Code (“Section 409A”) or shall comply with the requirements of such provision. Notwithstanding any provision of
this Agreement to the contrary, if Executive is a “specified employee” within the meaning of Section 409A, any payments or arrangements due upon a termination of Executive’s employment under any arrangement that constitutes a
“nonqualified deferral of compensation” within the meaning of Section 409A and which do not otherwise qualify under the exemptions under Treas. Regs. Section 1.409A-1 (including without limitation, the short-term deferral
exemption or the 
  

 13 








 
permitted payments under Treas. Regs. Section 1.409A-1(b)(9)(iii)(A)), shall be delayed and paid or provided on the earlier of (i) the date which is six months after Executive’s
“separation from service” (as such term is defined in Section 409A and the regulations and other published guidance thereunder) for any reason other than death, and (ii) the date of Executive’s death. The Company
acknowledges and agrees that if any payment, award, benefit or distribution (or any acceleration of any payment, award, benefit or distribution) made or provided to Executive or for Executive’s benefit in connection with this Agreement, or
Executive’s employment with the Company or the termination thereof (the “Payments”) are determined to be subject to the additional taxes, interest or penalties imposed by Section 409A, or any interest or penalties with
respect to such additional taxes, interest or penalties (such additional taxes, together with any such interest and penalties, are referred to collectively as the “Section 409A Tax”), then the Executive will be entitled to receive
an additional payment (an “409A Gross-Up Payment”) from the Company such that the net amount the Executive retains after paying any applicable Section 409A Tax and any federal, state or local income or FICA taxes on such 409A
Gross-Up Payment, shall be equal to the amount the Executive would have received if the Section 409A Tax were not applicable to the Payments. All determinations of the Section 409A Tax and 409A Gross-Up Payment, if any, will be made by tax
counsel or other tax advisers designated by Executive and approved by the Company, which approval won’t be unreasonably withheld or delayed. For purposes of determining the amount of the 409A Gross-Up Payment, if any, Executive will be deemed
to pay federal income tax at the actual marginal rate of federal income taxation in the calendar year in which the total Payments are made and state and local income taxes at the actual marginal rate of taxation in the state and locality of
Executive’s residence on the date the total Payments are made, net of the maximum reduction in federal income taxes that could be obtained from deduction of such state and local taxes. If the Section 409A Tax is determined by the Internal
Revenue Service, on audit or otherwise, to exceed the amount taken into account hereunder in calculating the 409A Gross-Up Payment (including by reason of any payment the existence or amount of which cannot be determined at the time of the 409A
Gross-Up Payment), the Company shall make another 409A Gross-Up Payment in respect of such excess (plus any interest, penalties or additions payable by Executive with respect to such excess). The Company and Executive shall each reasonably cooperate
with the other in connection with any administrative or judicial proceedings concerning the existence or amount of liability for Section 409A Tax with respect to the total Payments. The 409A Gross-Up Payments provided to Executive shall be made
no later than the tenth (10th) business day following the last date the Payments are made but in all events within the time period specified in Section 8.5 also. 

8.3 After any Termination Date, Executive shall have no duties or responsibilities that are inconsistent with having a
“separation from service” within the meaning of Section 409A as of the Termination Date and, notwithstanding anything in the Agreement to 

 

 14 








 
the contrary, distributions upon termination of employment of nonqualified deferred compensation may only be made upon a “separation from service” as determined under Section 409A
and such date shall be the Termination Date for purposes of this Agreement. Each payment under this Agreement or otherwise shall be treated as a separate payment for purposes of Section 409A. In no event may Executive, directly or indirectly,
designate the calendar year of any payment to be made under this Agreement which constitutes a “nonqualified deferral of compensation” within the meaning of Section 409A and to the extent an amount is payable within a time period, the
time during which such amount is paid shall be in the discretion of the Company. 
 8.4 Any amounts otherwise
payable to Executive following a termination of employment that are not so paid by reason of this Section 8 shall be paid as soon as practicable following, and in any event within thirty (30) days following, the date that is six months
after Executive’s separation from service (or, if earlier, the date of Executive’s death) together with interest on the delayed payment at the Company’s cost of borrowing. All reimbursements and in-kind benefits provided under this
Agreement shall be made or provided in accordance with the requirements of Section 409A. 
 8.5 To the
extent that any reimbursements pursuant to Section 4 or otherwise are taxable to Executive, any reimbursement payment due to Executive pursuant to such Section shall be paid to Executive on or before the last day of the Executive’s taxable
year following the taxable year in which the related expense was incurred. The reimbursements pursuant to Section 4 or otherwise are not subject to liquidation or exchange for another benefit and the amount of such reimbursements that Executive
receives in one taxable year shall not affect the amount of such reimbursements that Executive receives in any other taxable year. Any tax gross-up shall be made no later than the end of the calendar year next following the calendar year in which
the Executive remits the related tax. 
 9. Confidentiality, Invention Assignment and Non-Competition
Agreement. Executive agrees to be bound by the terms of the Employee Confidentiality, Invention Assignment and Non-Compete Agreement, a copy of which is attached hereto as Exhibit C and incorporated herein by reference (the
“Non-Compete Agreement”). Except as expressly set forth in this Agreement and the Non-Compete Agreement, Executive shall be subject to no contractual or similar restrictions on his right to terminate his employment hereunder or on
his activities after the Termination Date. 
 10. Non-Disparagement. During and after the Term, Executive
and the Company agree not to make any statement that criticizes, ridicules, disparages, or is otherwise derogatory of the other; provided, however, that nothing in this Agreement shall restrict either party from making truthful statements
(a) when required by law, subpoena, court order or the like; (b) when 
  

 15 








 
requested by a governmental, regulatory, or similar body or entity; (c) in confidence to a professional advisor for the purpose of securing professional advice; (d) in the course of
performing his duties during the Term; (e) from rebutting any statement made or written about them; or (f) from making normal competitive statements about the Company’s business or products. This provision shall not apply after three
(3) years from the date of termination of Executives employment with the Company. 
 11. Notices.
Except as otherwise specifically provided herein, any notice, consent, demand or other communication to be given under or in connection with this Agreement shall be in writing and shall be deemed duly given when delivered personally, when
transmitted by facsimile transmission, one (1) day after being deposited with Federal Express or other nationally recognized overnight delivery service or three (3) days after being mailed by first class mail, charges or postage prepaid,
properly addressed, if to the Company, at its principal office, and, if to Executive, at his address set forth following his signature below. Either party may change such address from time to time by notice to the other. 

12. Governing Law. This Agreement shall be governed by and construed and interpreted in accordance with the laws
of the State of North Carolina, exclusive of any choice of law rules. 
 13. Arbitration; Legal Fees.

 (a) Any dispute or controversy arising under or in connection with this Agreement (except with respect to
injunctive relief under Section 9) shall be settled exclusively by arbitration in North Carolina, in accordance with the rules of the American Arbitration Association for employment disputes as then in effect. Judgment may be entered on the
arbitrator’s award in any court having jurisdiction. 
 (b) In the event of any material contest or
dispute relating to this Agreement or the termination of Executive’s employment hereunder, each of the parties shall bear its own costs and expenses, except that the Company agrees to promptly reimburse Executive for his costs and expenses
(including reasonable attorneys’ fees and expenses) incurred by Executive in connection with such contest or dispute in the event Executive prevails, as determined by the arbitrator if in arbitration, by the court if pursuant to Section 9,
or as a separate arbitration if otherwise. The amount shall be paid within thirty (30) days of the award of the arbitration or court, which shall also specify the amount due. 

14. Amendments; Waivers. This Agreement may not be modified or amended or terminated except by an instrument in
writing, signed by Executive and a duly-authorized officer of the Company (other than Executive). By an instrument in writing similarly executed, either 

 

 16 








 
party may waive compliance by the other party with any provision of this Agreement that such other party was or is obligated to comply with or perform; provided, however, that such
waiver shall not operate as a waiver of, or estoppel with respect to, any other or subsequent failure. No failure to exercise and no delay in exercising any right, remedy, or power hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, remedy, or power hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, or power provided herein or by law or in equity. To be effective, any written waiver must
specifically refer to the condition(s) or provision(s) of this Agreement being waived. 
 15.
Inconsistencies. In the event of any inconsistency between any provision of this Agreement and any provision of any Company arrangement, the provisions of this Agreement shall control, unless Executive and the Company otherwise agree in a
writing that expressly refers to the provision of this Agreement that is being waived. 
 16. Assignment.
Except as otherwise specifically provided herein, neither party shall assign or transfer this Agreement nor any rights hereunder without the consent of the other party, and any attempted or purported assignment without such consent shall be void;
provided, however, that any assignment or transfer pursuant to a merger or consolidation, or the sale or liquidation of all or substantially all of the business and assets of the Company shall be valid, so long as the assignee or
transferee (a) is the successor to all or substantially all of the business and assets of the Company and (b) assumes the liabilities, obligations and duties of the Company, as contained in this Agreement, either contractually or as a
matter of law. Executive’s consent shall not be required for any such transaction. This Agreement shall otherwise bind and inure to the benefit of the parties hereto and their respective successors, penalties, assigns, heirs, legatees,
devisees, executors, administrators and legal representatives. 
 17. Voluntary Execution;
Representations. Executive acknowledges that (a) he has consulted with or has had the opportunity to consult with independent counsel of his own choosing concerning this Agreement and has been advised to do so by the Company and (b) he
has read and understands this Agreement, is competent and of sound mind to execute this Agreement, is fully aware of the legal effect of this Agreement, and has entered into it freely based on his own judgment and without duress. Executive
represents and covenants that his employment hereunder and compliance with the terms and conditions hereof will not conflict with or result in the breach by him of any agreement to which he is a party or by which he may be bound and in connection
with his employment with the Company he will not engage in any unauthorized use of any confidential or proprietary information he may have obtained in connection with his employment with any other employer. The Company represents and warrants that
it is fully authorized, by any person or body whose authorization is required, to enter into this Agreement and to perform its obligations under it. 
  

 17 








 18. Headings. The headings of the Sections and sub-sections contained
in this Agreement are for convenience only and shall not be deemed to control or affect the meaning or construction of any provision of this Agreement. 

19. Beneficiaries/References. Executive shall be entitled, to the extent permitted under applicable law, to select
and change a beneficiary or beneficiaries to receive any compensation or benefit hereunder following Executive’s death by giving written notice thereof. In the event of Executive’s death or a judicial determination of his incompetence,
references in this Agreement to Executive shall be deemed, where appropriate, to refer to his beneficiary, estate or other legal representative. 

20. Survivorship. Except as otherwise set forth in this Agreement, the respective rights and obligations of the
parties shall survive any termination of Executive’s employment. 
 21. Severability. Whenever
possible, each provision or portion of any provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law but the invalidity or unenforceability of any provision or portion of any provision of this
Agreement in any jurisdiction shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of this Agreement, including that provision or portion of any provision, in any
other jurisdiction. 
 22. No Mitigation/No Offset. Executive shall be under no obligation to seek other
employment or to otherwise mitigate the obligations of the Company under this Agreement, and there shall be no offset against amounts or benefits due to Executive under this Agreement or otherwise on account of any claim (other than any preexisting
debts then due in accordance with their terms) the Company may have against him or any remuneration or other benefit earned or received by Executive after such termination. 

23. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an
original, but all such counterparts shall together constitute one and the same instrument. Signatures delivered by facsimile or PDF shall be effective for all purposes. 

24. Entire Agreement. This Agreement and the agreements described in the attached Exhibits contain the entire
agreement of the parties and supersedes all prior or contemporaneous negotiations, correspondence, understandings and agreements between the parties, regarding the subject matter of this Agreement.

 Exhibit A 

FORM OF GENERAL RELEASE OF ALL CLAIMS 

THIS GENERAL RELEASE OF ALL CLAIMS (this “General Release”), dated as of
[____________________________], 2010, is made by and between Andrew I. Koven (the “Executive”) and Inspire Pharmaceuticals, Inc. (the “Company”). 

WHEREAS, the Company and Executive are parties to that certain Employment Agreement, dated as of April 2, 2010
(the “Employment Agreement”); 
 WHEREAS, Executive’s employment with the Company has
been terminated and Executive is entitled to receive severance and other benefits, as set forth in Section 5 of the Employment Agreement subject to the execution of this General Release; 

WHEREAS, in consideration for Executive’s signing of this General Release, the Company will provide Executive with
such severance and benefits pursuant to the Employment Agreement; and 
 WHEREAS, except as otherwise expressly
set forth herein, the parties hereto intend that this General Release shall effect a full satisfaction and release of the obligations described herein owed to Executive by the Company and to the Company by Executive. 

NOW, THEREFORE, in consideration of the premises, the mutual covenants of the parties hereinafter set forth and other
good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby covenant and agree as follows: 

1. Executive, for himself, Executive’s spouse, heirs, administrators, children, representatives, executors, successors, assigns, and
all other individuals and entities claiming through Executive, if any (collectively, the “Executive Releasers”), does hereby release, waive, and forever discharge the Company and each of its respective agents, subsidiaries,
parents, affiliates, related organizations, employees, officers, directors, attorneys, successors, and assigns in their capacities as such (collectively, the “Employer Releasees”) from, and does fully waive any obligations of
Employer Releasees to Executive Releasers for, any and all liability, actions, charges, causes of action, demands, damages, or claims for relief, remuneration, sums of money, accounts or expenses (including attorneys’ fees and costs) of
any kind whatsoever, whether known or unknown or contingent or absolute, which heretofore has been or which hereafter may be suffered or sustained, directly or indirectly, by Executive Releasers in consequence of, arising out of, or in any way
relating to: (a) Executive’s employment with the Company; (b) the termination of Executive’s employment with the Company; (c) the Employment Agreement; or (d) any events occurring on or prior to the date of this General
Release. The foregoing release 
  

 20 








 
and discharge, waiver and covenant not to sue includes, but is not limited to, all waivable claims and any obligations or causes of action arising from such claims, under common law including
wrongful or retaliatory discharge, breach of contract (including but not limited to any claims under the Employment Agreement other than claims for unpaid severance benefits, bonus or Base Salary earned thereunder) and any action arising
in tort including libel, slander, defamation or intentional infliction of emotional distress, and claims under any federal, state or local statute including the Age Discrimination in Employment Act (“ADEA”), Title VII of the
Civil Rights Act of 1964, the Civil Rights Act of 1866 and 1871 (42 U.S.C. § 1981), the National Labor Relations Act, the Fair Labor Standards Act, the Employee Retirement Income Security Act, the Americans with Disabilities Act of
1990, the Rehabilitation Act of 1973, or the discrimination or employment laws of any state or municipality, and/or any claims under any express or implied contract which Executive Releasers may claim existed with Employer Releasees. This also
includes a release of any claims for wrongful discharge and all claims for alleged physical or personal injury, emotional distress relating to or arising out of Executive’s employment with the Company or any of its subsidiaries or affiliates or
the termination of that employment; and any claims under the WARN Act or any similar law, which requires, among other things, that advance notice be given of certain work force reductions. Notwithstanding anything contained in this
Section 1 above to the contrary, nothing contained in herein shall constitute a release by any Executive Releaser of any of his, her or its rights or remedies available to him, her or it, at law or in equity, related to, on account of,
in connection with or in any way pertaining to the enforcement of: (i) any right to indemnification, advancement of legal fees or directors and officers liability insurance coverage existing under the constituent documents of the Company
or applicable state corporate, limited liability company and partnership statutes or pursuant to any agreement, plan or arrangement; (ii) any rights to the receipt of employee benefits which vested on or prior to the date of this General
Release; (iii) the right to receive severance and other benefits under the Employment Agreement; (iv) the right to continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act; (v) any rights of
Executive under the Employment Agreement with respect to (A) the gross-up protections set forth in Sections 6 and 8.2 of the Employment Agreement, (B) amounts due upon a Change in Control occurring after a termination of employment that
occurs in anticipation of a Change in Control as set forth in Section 5.6, and (C) any equity rights; or (vi) this General Release or any of its terms or conditions. 

2. Excluded from this General Release and waiver are any claims which cannot be waived by applicable law, including but not limited to
the right to participate in an investigation conducted by certain government agencies. Executive does, however, waive Executive’s right to any monetary recovery should any government agency (such as the Equal Employment Opportunity
Commission) pursue any claims on Executive’s behalf. Executive represents and warrants that Executive has not filed any complaint, charge, or lawsuit against the Employer Releasees with any government agency or any court. 

3. Executive agrees never to seek personal recovery from any Employer Releasee in any forum for any claim covered by the above waiver and
release language, except that Executive 
  

 21 








 
may bring a claim under the ADEA to challenge this General Release. If Executive violates this General Release by suing an Employer Releasee (excluding any claim by Executive under the ADEA or as
otherwise set forth in Section 1 hereof), then Executive shall be liable to the Employer Releasee so sued for such Employer Releasee’s reasonable attorneys’ fees and other litigation costs incurred in defending against such a
suit. Nothing in this General Release is intended to reflect any party’s belief that Executive’s waiver of claims under ADEA is invalid or unenforceable, it being the intent of the parties that such claims are waived. 

4. Each party agrees that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed
or construed at any time to be an admission by any party of any improper or unlawful conduct. 
 5. Each party acknowledges and
recites that he or it has: 
 (a) executed this General Release knowingly and voluntarily; 

(b) had a reasonable opportunity to consider this General Release; 

(c) read and understands this General Release in its entirety; 

(d) been advised and directed orally and in writing (and this subparagraph (d) constitutes such written
direction) to seek legal counsel and any other advice such party wishes with respect to the terms of this General Release before executing it; and 

(e) relied solely on such party’s own judgment, belief and knowledge, and such advice as such party may have
received from such party’s legal counsel. 
 6. Section 13 of the Employment Agreement, which shall survive the
expiration of the Employment Agreement for this purpose, shall apply to any dispute with regard to this release. 
 7. Executive
acknowledges and agrees that (a) his execution of this General Release has not been forced by any employee or agent of the Company, and Executive has had an opportunity to negotiate the terms of this General Release and (b) he has been
offered twenty-one (21) calendar days after receipt of this General Release to consider its terms before executing
it.1 Executive shall have seven (7) calendar days
from the date he executes this General Release to revoke his or her waiver of any ADEA claims by providing written notice of the revocation to the Company, as provided in Section 11 of the Employment Agreement. 

8. Capitalized terms used but not defined in this General Release have the meanings ascribed to such terms in the Employment Agreement.

  
  

1
     In the event the Company determines that Employee’s termination constitutes “an exit incentive or other employment termination program offered to a
group or class of employees” under the ADEA, the Company will provide Employee with: (1) 45 days to consider the General Release; and (2) the disclosure schedules required for an effective release under the ADEA. 

 

 22 








 9. This General Release may be executed by the parties in one or more counterparts, each of
which shall be an original and all of which shall together constitute one and the same instrument. Each counterpart may be delivered by facsimile transmission or e-mail (as a .pdf, .tif or similar un-editable attachment), which
transmission shall be deemed delivery of an originally executed counterpart hereof. 
 IN WITNESS WHEREOF, the
parties hereto have executed this General Release as of the day and year first above written.

 Exhibit B 

PARACHUTE TAX INDEMNITY PROVISIONS 

This Exhibit B sets forth the terms and provisions applicable to the Executive pursuant to the provisions of Section 6 of the
Agreement. This Exhibit B shall be subject in all respects to the terms and conditions of the Agreement. Capitalized terms used without definition in this Exhibit B shall have the meanings set forth in the Agreement. 

(A) In the event that Executive shall become entitled to payments and/or benefits provided by this Agreement or any other amounts in the
“nature of compensation” (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, or any arrangement or agreement with any person whose actions result in a change of ownership or
effective control or a change in the ownership of a substantial portion of the assets of the corporation covered by Code Section 280G(b)(2) (a “280G Change of Control”) or any person affiliated with the Company or such person) as a
result of a 280G Change of Control (collectively the “Company Payments”), and such Company Payments will be subject to the tax (the “Excise Tax”) imposed by Code Section 4999 (and any similar tax that may hereafter be
imposed by any taxing authority), the Company shall pay to Executive at the time specified below (i) an additional amount (the “Gross-Up Payment”) such that the net amount retained by Executive, after deduction of any Excise Tax on
the Company Payments and any U.S. federal, state, and for local income or payroll tax upon the Gross-up Payment provided for by this paragraph, but before deduction for any U.S. federal, state, and local income or payroll tax on the Company
Payments, shall be equal to the Company Payments and (ii) an amount equal to the product of any deductions disallowed for federal, state or local income tax purposes because of the inclusion of the Gross-Up Payment in Executive’s adjusted
gross income multiplied by Executive’s actual marginal rate of federal, state or local income taxation, respectively, for the calendar year in which the Gross-Up Payment is to be made. 

(B) In the event that the Internal Revenue Service or court ultimately makes a determination that the excess parachute payments plus the
base amount is an amount other than as determined initially, an appropriate adjustment shall be made with regard to the Gross-Up Payment as applicable to reflect the final determination. 

(C) For purposes of determining whether any of the Company Payments and Gross-Up Payments (collectively the “Total Payments”)
will be subject to the Excise Tax and the amount of such Excise Tax, (i) the Total Payments shall be treated as “parachute payments” within the meaning of Code Section 280G(b)(2), and all “parachute payments” in excess
of the “base amount” (as defined under Code Section 280G(b)(3)) shall be treated as subject to the Excise Tax, unless and except to the extent that, in the opinion of the Company’s independent certified public accountants
appointed prior to any change in ownership (as defined under Code Section 280G(b)(2)) or tax counsel selected by such accountants or the Company (the “Accountants”) such Total Payments (in whole or in part) either do not constitute
“parachute payments,” including giving effect to the recalculation of stock options in accordance with Treasury 
  


 24 








 
Regulation Section 1.280G-1, Q&A 33, represent reasonable compensation for services actually rendered within the meaning of Code Section 280G(b)(4) in excess of the “base
amount” or are otherwise not subject to the Excise Tax, and (ii) the value of any non-cash benefits or any deferred payment or benefit shall be determined by the Accountants in accordance with the principles of Code Section 280G. To
the extent permitted under Revenue Procedure 2003-68, the value determination shall be recalculated to the extent it would be beneficial to Executive. In the event that the Accountants are serving as accountant or auditor for the individual, entity
or group effecting the Change in Control, Executive may appoint with the approval of the Company, which approval shall not be unreasonable or unreasonably delayed, another nationally recognized accounting firm to make the determinations hereunder
(which accounting firm shall then be referred to as the “Accountants” hereunder). All determinations hereunder shall be made by the Accountants which shall provide detailed supporting calculations both to the Company and Executive at such
time as it is requested by the Company or Executive supported by such opinions or other confirmations as will let the Company and the Executive rely therein for purposes of filing their tax returns. The determination of the Accountants shall be
final and binding upon the Company and Executive. 
 (D) For purposes of determining the amount of the Gross-Up Payment,
Executive’s actual U.S. federal income tax rate in the calendar year in which the Gross-Up Payment is to be made and state and local income taxes at Executive’s actual rate of taxation in the state and locality of Executive’s
residence for the calendar year in which the Company Payment is to be made, net of the maximum reduction in U.S. federal income taxes which could be obtained from deduction of such state and local taxes if paid in such year, shall be used. In the
event that the Excise Tax is subsequently determined by the Accountants to be less than the amount taken into account hereunder at the time the Gross-Up Payment is made, Executive shall repay to the Company, at the time that the amount of such
reduction in Excise Tax is finally determined, the portion of the prior Gross-Up Payment attributable to such reduction (plus the portion of the Gross-Up Payment attributable to the Excise Tax and U.S. federal, state and local income tax imposed on
the portion of the Gross-up Payment being repaid by Executive if such repayment results in a reduction in Excise Tax or a U.S. federal, state and local income tax deduction), plus interest on the amount of such repayment at the rate provided in Code
Section 1274(b)(2)(B). Notwithstanding the foregoing, in the event any portion of the Gross-Up Payment to be refunded to the Company has been paid to any U.S. federal, state and local tax authority, repayment thereof (and related amounts) shall
not be required until actual refund or credit of such portion has been made to Executive, and interest payable to the Company shall not exceed the interest received or credited to Executive by such tax authority for the period it held such portion.
Executive and the Company shall mutually agree upon the course of action to be pursued (and the method of allocating the expense thereof) if Executive’s claim for refund or credit is denied. 

(E) In the event that the Excise Tax is later determined by the Accountant or the Internal Revenue Service to exceed the amount taken
into account hereunder at the time the Gross-Up Payment is made (including by reason of any payment the existence or amount of which cannot be determined at the time of the Gross-Up Payment), the Company shall make an additional

  

 25 








 
Gross-Up Payment in respect of such excess (plus any interest or penalties payable with respect to such excess) at the time that the amount of such excess is finally determined. 

(F) The Gross-up Payment or portion thereof provided for above shall be paid not later than the sixtieth (60) day following a 280G
Change of Control which subjects Executive to the Excise Tax; provided, however, that if the amount of such Gross-up Payment or portion thereof cannot be finally determined on or before such day, the Company shall pay to Executive on such day an
estimate, as determined in good faith by the Accountant, of the minimum amount of such payments and shall pay the remainder of such payments, as soon as the amount thereof can reasonably be determined, but in no event later than the ninetieth
(90th) day after the occurrence of the event subjecting Executive to the Excise Tax. Notwithstanding any other provision of this Agreement, all Gross-Up Payments under this Exhibit B shall be paid pursuant to Section 8 of the Agreement. In
the event that the amount of the estimated payments exceeds the amount subsequently determined to have been due, subject to Paragraph (G) below, such excess shall constitute a loan by the Company to Executive, payable on the fifth
(5th) day after demand by the Company (together with interest at the rate provided in Code Section 1274(b)(2)(B)). 

(G) In the event of any controversy with the Internal Revenue Service (or other taxing authority) with regard to the Excise Tax,
Executive shall permit the Company to control issues related to the Excise Tax (at its expense), but Executive shall control any other issues unrelated to the Excise Tax. In the event that the issues are interrelated, Executive and the Company shall
in good faith cooperate. In the event of any conference with any taxing authority as to the Excise Tax or associated income taxes, Executive shall permit the representative of the Company to accompany Executive, and Executive and his representative
shall cooperate with the Company and its representative. 
 (G) The Company shall be responsible for all charges of the
Accountant. 
 (I) The Company and Executive shall promptly deliver to each other copies of any written communications, and
summaries of any verbal communications, with any taxing authority regarding the Excise Tax covered by this provision. 
 (G)
Nothing in this Exhibit B is intended to violate the Sarbanes-Oxley Act and to the extent that any advance or repayment obligation hereunder would do so, such obligation shall be modified so as to make the advance a nonrefundable payment to
Executive and the repayment obligation null and void. 
  

 26 








 Exhibit C 

EMPLOYEE CONFIDENTIALITY, INVENTION ASSIGNMENT 

AND NON-COMPETE AGREEMENT 

THIS EMPLOYEE CONFIDENTIALITY, INVENTION ASSIGNMENT AND NON-COMPETE AGREEMENT (“Agreement”) is made as
of the date set forth on the signature page below between Inspire Pharmaceuticals, Inc. (“Inspire”), and the person whose name is set forth on the signature page below as Employee (“Employee”). 

In consideration of Employee’s employment or continued employment by Inspire, with the intention that this Agreement
shall apply to the entire period of Employee’s employment with Inspire (including the period prior to the date of this Agreement), Employee hereby agrees as follows: 

1. CONFIDENTIAL INFORMATION DEFINED. “Confidential Information” means trade secrets, proprietary information and
materials, and confidential knowledge and information which includes, but is not limited to, matters of a technical nature (such as discoveries, ideas, concepts, designs, drawings, specifications, techniques, models, diagrams, test data, scientific
methods and know-how, and materials such as reagents, substances, chemical compounds, subcellular constituents, cell or cell lines, organisms and progeny, and mutants, derivatives or replications derived from or relating to any of the foregoing
materials), and matters of a business nature (such as the identity of customers and prospective customers, the nature of work being done for or discussed with customers or prospective customers, suppliers, marketing techniques and materials,
marketing and development plans, pricing or pricing policies, financial information, plans for further development, and any other information of a similar nature not available to the public). 

“Confidential Information” shall not include information that: (a) was in Employee’s possession or in
the public domain before receipt from the Company, as evidenced by the then existing publication or other public dissemination of such information in written or other documentary form; (b) becomes available to the public through no fault of
Employee; (c) is received in good faith by Employee from a third party who is known to the Employee to be not subject to an obligation of confidentiality to the Company or any other party; or (d) is required by a judicial or administrative
authority or court having competent jurisdiction to be disclosed by Employee, provided that Employee shall promptly notify the Company and not attempt to prevent the Company from opposing or limiting such order. 

2. NON-DISCLOSURE OF CONFIDENTIAL INFORMATION OF INSPIRE. Employee acknowledges that, during the period of Employee’s
employment with Inspire, Employee has had or will have access to Confidential Information of Inspire. Therefore, Employee agrees that both during and after the period of Employee’s employment with Inspire, Employee shall not, without the prior
written approval of Inspire, directly or indirectly (a) reveal, report, publish, 
  

 27 








 
disclose or transfer any Confidential Information of Inspire to any person or entity, or (b) use any Confidential Information of Inspire for any purpose or for the benefit of any person or
entity, except in the good faith performance of Employee’s work for Inspire. 
 3. NON-DISCLOSURE OF CONFIDENTIAL
INFORMATION OF OTHERS. Employee acknowledges that, during the period of Employee’s employment with Inspire, Employee may have had or will have access to Confidential Information of third parties who have given Inspire the right to use such
Confidential Information, subject to a non-disclosure agreement between Inspire and such third party. Therefore, Employee agrees that both during and after the period of Employee’s employment with Inspire, Employee shall not, without the prior
written approval of Inspire, directly or indirectly (a) reveal, report, publish, disclose or transfer any Confidential Information of such third parties to any person or entity, or (b) use any Confidential Information of such third parties
for any purpose or for the benefit of any person or entity, except in the good faith performance of Employee’s work for Inspire or to comply with an order from any court of competent jurisdiction. 

4. PROPERTY OF INSPIRE. Employee acknowledges and agrees that all Confidential Information of Inspire and all reports, drawings,
blueprints, materials, data, code, notes and other documents and records (other than Employee’s personal address book), whether printed, typed, handwritten, videotaped, transmitted or transcribed on data files or on any other type of media, and
whether or not labeled or identified as confidential or proprietary, made or compiled by Employee, or made available to Employee, during the period of Employee’s employment with Inspire (including the period prior to the date of this Agreement)
concerning Inspire’s Confidential Information are and shall remain Inspire’s property and shall be delivered to Inspire within five (5) business days after the termination of such employment with Inspire or at any earlier time on
request of Inspire. Employee shall not retain copies of such Confidential Information, documents and records. 
 5.
PROPRIETARY NOTICES. Employee shall not, and shall not permit any other person to, remove any proprietary or other legends or restrictive notices contained in or included in any Confidential Information. 

6. INVENTIONS. 

(a) Employee shall promptly, from time to time, fully inform and disclose to Inspire in writing all inventions,
copyrightable material, designs, improvements and discoveries of any kind which Employee now has made, conceived or developed (including prior to the date of this Agreement), or which Employee may later make, conceive or develop, during the period
of Employee’s employment with Inspire, which pertain to or relate to Inspire’s business or any of the work or businesses carried on by Inspire (“Inventions”). This covenant applies to all such Inventions, whether or not they are
eligible for patent, copyright, trademark, trade secret or other legal protection; and whether or not they are conceived and/or developed by Employee alone or 

 

 28 








 
with others; and whether or not they are conceived and/or developed during regular working hours; and whether or not they are conceived and/or developed at Inspire’s facility or not.

 (b) Inventions shall not include any inventions made, conceived or developed by Employee prior to
Employee’s employment with Inspire, a complete list of which is set forth on Schedule A attached. 
 (c)
All Inventions shall be the sole and exclusive property of Inspire, and shall be deemed part of the Confidential Information of Inspire for purposes of this Agreement, whether or not fixed in a tangible medium of expression. Employee hereby assigns
all Employee’s rights in all Inventions and in all related patents, copyrights and trademarks, trade secrets and other proprietary rights therein to Inspire. Without limiting the foregoing, Employee agrees that any copyrightable material shall
be deemed to be “works made for hire” and that Inspire shall be deemed the author of such works under the United States Copyright Act, provided that in the event and to the extent such works are determined not to constitute “works
made for hire”, Employee hereby irrevocably assigns and transfers to Inspire all right, title and interest in such works. 

(d) Employee shall assist and cooperate with Inspire, both during and after the period of Employee’s employment with
Inspire, at Inspire’s sole expense, to allow Inspire to obtain, maintain and enforce patent, copyright, trademark, trade secret and other legal protection for the Inventions. Employee shall sign such truthful documents, and do such things
necessary, to obtain such protection and to vest Inspire with full and exclusive title in all Inventions against infringement by others. Employee hereby appoints the Secretary of Inspire as Employee’s attorney-in-fact to execute any truthful
documents on Employee’s behalf for this purpose. 
 (e) Employee shall not be entitled to any additional
compensation for any and all Inventions made during the period of Employee’s employment with Inspire. 
 7. COVENANT NOT
TO COMPETE. If Employee is, at any time during Employee’s period of employment with Inspire, employed in the discovery or development areas of the Company in a non-clerical position, or as a director level or higher level senior manager of
the Company, then this Section 7 shall apply. Employee and Inspire agree that the services rendered by the Employee are unique and irreplaceable, and that competitive use and knowledge of any Confidential Information would substantially and
irreparably injure Inspire’s business, prospects and good will. Employee and Inspire also agree that Inspire’s business is global in nature due to the type of products and/or services being provided. Therefore, Employee agrees that during
the period of Employee’s employment with Inspire and for a period of one (1) year thereafter, Employee shall not, directly or indirectly, through any other person, firm, corporation or other entity (whether as an officer, director,
employee, partner, consultant, holder of equity or debt investment, lender or in any other manner or capacity): 
  

 29 








 (a) develop, sell, market, offer to sell products and/or services anywhere
in the world that have the same or similar technological approach or technology platform (e.g., same receptors (such as P2Y), same mechanism of action (such as mucociliary clearance)) and have the same indication as those being developed, offered or
sold by Inspire on the date of the termination of Employee’s employment with Inspire for any reason, provided that the foregoing shall not be violated by Executive’s activities with an entity where the portion of the competitive business
involved is less than 5% of the revenues of the portion of the entity that is under the Employee’s supervision; 

(b) solicit, induce, encourage or attempt to induce or encourage any employee or consultant of Inspire to terminate his
or her employment or consulting relationship with Inspire, or to breach any other obligation to Inspire (other than advertising not specifically targeted at the Company’s employees and serving as a reference upon request), however,
notwithstanding the foregoing, Employee may engage in the activities described in this Section 7(b) with respect to one executive who worked with Employee in the past and joined the Company without it violating this provision; or 

(c) interfere with, disrupt, alter or attempt to disrupt or alter the relationship, contractual or otherwise, between
Inspire and any consultant, contractor, customer, potential customer, or supplier of Inspire. 
 Employee
acknowledges that the foregoing geographic, activity and time limitations contained in this Section 7 are reasonable and properly required for the adequate protection of Inspire’s business. In the event that any such geographic, activity
or time limitation is deemed to be unreasonable by a court, Employee shall submit to the reduction of either said activity or time limitation to such activity or period as the court shall deem reasonable. In the event that Employee is in violation
of the aforementioned restrictive covenants, then the time limitation thereof shall be extended for a period of time equal to the pendency of such proceedings, including appeals. 

8. DISCLOSURE OF THIS AGREEMENT. Employee hereby authorizes Inspire to notify others, including but not limited to customers of
Inspire and any of Employee’s future employers, of the terms of this Agreement and Employee’s responsibilities under this Agreement. 

9. SPECIFIC PERFORMANCE. Employee acknowledges that money damages alone would not adequately compensate Inspire in the event of a
breach or threatened breach by Employee of this Agreement, and that, in addition to all other remedies available to Inspire at law or in equity, Inspire shall be entitled to injunctive relief for the enforcement of its rights and to an accounting of
profits made during the period of such breach. 
 10. NO RIGHTS GRANTED. Employee understands that nothing in this
Agreement shall be deemed to constitute, by implication or otherwise, the grant by Inspire to the employee of any 
  

 30 








 
license or other right under any patent, patent application or other intellectual property right or interest belonging to Inspire. 

11. SEVERABILITY. 

(a) Each of the covenants provided in this Agreement are separate and independent covenants. If any provision of this
Agreement shall be determined to be invalid or unenforceable, the remainder of this Agreement shall not be affected thereby and any such invalid or unenforceable provision shall be reformed so as to be valid and enforceable to the fullest extent
permitted by law. 
 (b) It is not a defense to the enforcement of any provision of this Agreement that Inspire
has breached or failed to perform any obligation or covenant hereunder or under any other agreement or understanding between Employee and Inspire. 

12. GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of North Carolina
without regard to conflict of law rules. All suits and claims shall be made only in state or federal courts located in North Carolina. 

13. SUPERSEDES OTHER AGREEMENTS. This Agreement contains the entire agreement of the parties with respect to subject matter hereof
and supersedes all previous agreements and understandings between the parties with respect to its subject matter. 
 14.
AMENDMENTS. This Agreement may not be changed, modified, released, discharged, abandoned or otherwise terminated in whole or in part except by an instrument in writing, agreed to and signed by the Employee and a duly authorized officer of
Inspire. 
 15. ACKNOWLEDGEMENTS. THE EMPLOYEE ACKNOWLEDGES THAT (i) THE EMPLOYEE HAS READ AND FULLY UNDERSTANDS THIS
AGREEMENT; (ii) THE EMPLOYEE HAS BEEN GIVEN THE OPPORTUNITY TO ASK QUESTIONS; (iii) THE EMPLOYEE HAS RECEIVED A COPY OF THIS AGREEMENT, THE ORIGINAL OF WHICH WILL BE RETAINED IN THE EMPLOYEE’S PERSONNEL FILE; AND (iv) THE
EMPLOYEE’S OBLIGATIONS UNDER THIS AGREEMENT SURVIVE THE TERMINATION OF THE EMPLOYEE’S EMPLOYMENT WITH INSPIRE FOR ANY REASON.
