 EMPLOYMENT AGREEMENT 
 This EMPLOYMENT AGREEMENT (the “Agreement”) made as of this 13th day
of July, 2006, and shall be effective October 1, 2005 (the “Effective Date”), by and between the MOHEGAN TRIBAL GAMING AUTHORITY (the “Authority” or the “Employer”), an instrumentality of THE MOHEGAN TRIBE OF
INDIANS OF CONNECTICUT (the “Tribe”), a sovereign Indian nation having an address of One Mohegan Sun Boulevard, Uncasville, Connecticut 06382, and LEO M CHUPASKA, residing at 68 Swanty Johnson Road, Uncasville, Connecticut 06382
(“Executive”). 
 WITNESSETH: 
 WHEREAS, the Employer owns and operates, among other things, the Mohegan Sun casino and resort in Uncasville, Connecticut, a harness racetrack located in Wilkes-Barre, Pennsylvania known as Pocono Downs, along with several off-track
wagering facilities located in the State of Pennsylvania, as well as investments in other proposed gaming enterprises and other businesses (as presently existing and hereafter developed, the “Business”); and 
 WHEREAS, the Employer and Executive entered into that certain employment agreement dated the 22nd day of March 1999 (but effective October 1, 1998), providing for the continued employment of Executive by the Tribe (the “1999 Agreement”); and

 WHEREAS, the parties hereto have agreed to terminate the 1999 Agreement and to enter into this Agreement; and 
 WHEREAS the Employer is desirous of assuring that Executive has the authority to fully carry out his duties hereunder by being responsible to the
Employer, acting through its Chief Executive Officer. 
 NOW, THEREFORE, in consideration of the promises and the mutual covenants, terms and
conditions hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency whereof is specifically acknowledged, the parties hereto hereby agree as follows: 
 1. Termination of the 1999 Agreement

 Page 1 of 9 

 
Executive Officer hereafter assign to him. Such duties shall include, but not be limited to, cash management, investments with financial institutions,
banking relationships, administering corporate financial functions and supervising the financial accounting department. For purposes of clarification, such duties shall apply to the entire Business of the Employer, including any portion of the
Business operated by Employer or through its direct or indirect subsidiaries, including but not limited to The Mohegan Sun. Executive shall serve as Chief Financial Officer of The Mohegan Sun. Executive shall report exclusively to the Chief
Executive Officer of the Employer. The Employer shall not restrict, reduce or otherwise limit Executive’s responsibility or authority without his consent. 
 (C) Executive shall devote his best efforts and ability and all required business time to the performance of his duties and responsibilities hereunder to achieve the goals set forth in the Employer’s annual
business plan. Executive shall perform all of his duties to the Employer faithfully, competently, and diligently. 
 (D) Except for actions
of the Executive that could be the basis for termination for Cause as set forth in Paragraph 9(C), below, the Employer shall indemnify, defend, and hold Executive harmless, including the payment of reasonable attorney fees, if the Employer does not
directly provide Executive’s defense, from and against all claims made by anyone, including, but not limited to, a corporate entity, company, other employee, agent, patron, tribal member, or any member of the general public with respect to any
claim that asserts as a basis, any acts, omissions, or other circumstances involving the performance of Executive. 
 3. Effective
Date 
 This Agreement shall be effective from the date set forth in the opening paragraph of this Agreement (the “Effective
Date”). 
 4. Term 
 This Agreement shall govern Executive’s employment with the Employer from the Effective Date through and including December 31, 2008. This Agreement, including this paragraph, shall automatically renew for an additional term of
five years unless either party shall notify the other of its intention to terminate, or unless otherwise terminated as provided herein. Any such notice of intention to terminate shall be delivered not later than one hundred and twenty
(120) days prior to the end of the then current term and shall be effective at the end of such term, except as otherwise provided herein. 
 5. Base Annual Salary 
 Commencing with the Effective Date and until December 31, 2006, the Employer shall pay
Executive a Base Annual Salary in the amount of $547,000.00 in equal weekly installments. Commencing January 1, 2007, and on each January 1 thereafter during the term of this Agreement, the Base Annual Salary shall be increased in an
amount mutually agreed to by Executive and the Employer, which amount shall in no event be less than 5% of the then current Base Annual Salary. 
  

 Page 2 of 9 

 6. Annual Bonus 
 The Employer shall determine an annual bonus payable to Executive, the amount of which shall be based upon the business plan and financial goals of the
Employer as established at the beginning of each fiscal year. The annual bonus shall be not less than 33 1/3% of
the Annual Base Salary in effect for the period for which the annual bonus is to be paid. The annual bonus for the previous fiscal year shall be paid no later than October 31 of each year during the term. 
 7. Life Insurance 
 (A) The
Employer may, within its discretion, at any time during the term of this Agreement apply for and procure as owner and for its own benefit insurance on the life of Executive, in such amounts and in such form as the Employer may choose. Executive
shall have no interest whatsoever in any such policies, but he shall upon request by the Employer submit to such medical examinations, supply such information, and execute such documents as may be required by the Employer or the insurance companies
to whom the Employer has made application. 
 (B) So long as Executive is employed hereunder, the Employer shall maintain a life insurance
policy on the life of Executive in the face amount of $168,000. The Employer shall be and remain the owner of such policy of life insurance and shall enjoy all incidents of ownership including the right to designate the beneficiary and the right to
borrow on such policy; provided, however, that the beneficiary of such policy shall be the spouse of the Executive, his child or children, trustees for their benefit, his estate or any one or more of them; and provided further, that the Employer
agrees (if such policy has a cash surrender value) that it will not exercise its right to borrow on such policy. The Employer shall pay all premiums on such policy when due, and, in the event of the death of Executive during employment, the Employer
shall be a beneficiary of the policy to the extent of the aggregate amount of premium paid. 
 8. Reimbursement of Certain Expenses;
Vacation; Medical Benefits 
 (A) The Employer will reimburse Executive for necessary and reasonable business expenses incurred by him
in the performance of his duties hereunder, provided, that he shall obtain the approval for such expenditures in accordance with the procedures adopted by the Employer from time to time and generally-applicable to its executive-level employees,
including such procedures with respect to submission of appropriate documentation and receipts. Failure by Executive to follow such procedures shall entitle the Employer to refuse to reimburse Executive for such expenses until such time as such
failure has been cured. It is understood and agreed that Employer shall not be responsible for any expense of Executive for leasing or operation of a vehicle for Executive (except that Executive shall be entitled to reimbursement for the expenses,
including mileage, actually incurred in connection with his use of his automobile for the business-related purposes of the Employer), nor for any expense of Executive for legal expenses or tax planning expenses incurred by Executive in interpreting
this or any other agreement between Executive and Employer. 
 (B) Executive shall be entitled to four weeks paid vacation per fiscal year.

 (C) Executive shall participate in such employee benefit plans and programs (including but not limited to medical and life insurance
programs) as are now or may hereafter be adopted 

  

 Page 3 of 9 

 
by the Employer for its executive employees and their families. Employer shall continue to provide such medical insurance coverage for a period of one
(1) year after any termination by Employer of Executive’s employment hereunder if such termination was without Cause, as hereinafter defined. 
 9. Disability; Termination 
 (A) If Executive shall become unable to perform all of his duties
set forth in Paragraph 1 of this Agreement due to mental or physical disability, all compensation and benefits provided in this Agreement shall continue to be paid and provided in full for a period not exceeding one hundred and eighty
(180) consecutive days. Upon completion of such one hundred and eighty (180) days (or if Executive shall be disabled by the same incapacity for an aggregate period of one hundred and eighty (180) days in any period of three hundred
and sixty (360) consecutive days by the same incapacity) the Employer may, at its sole option, suspend Executive’s employment until Executive is recovered (as reasonably certified by a physician designated by the Employer) from such mental
or physical disability. During any period of suspension on account of disability, Executive shall receive only such compensation as may be provided under the disability insurance described in Paragraph 9(B). If the physician designated by the
Employer certifies that Executive is permanently disabled, Employer’s obligations under this Agreement shall cease; provided, however, Executive shall be entitled to the disability benefits set forth in Paragraph 9(B), below. 
 (B) Employer, at the sole expense of Employer, shall provide disability insurance coverage for Executive. Such policy shall provide payment of 50% of
Executive’s Base Annual Salary commencing with suspension or termination of employment, pursuant to Paragraph 9(A), above, by reason of physical or mental disability, and for a period of two (2) years if such disability was the result of
injury, and to age 65 if such disability was the result of physical or mental illness. In the event the Employer is unable to obtain disability insurance in the amount required, or is unable to obtain all or part of such insurance at standard rates,
the Employer shall at its option obtain part or all of such insurance at non-standard rates or shall self-insure in whole or in part for the time periods set forth in this paragraph. 
 (C) Subject to the provisions of this paragraph, the Employer may terminate Executive’s employment for Cause, defined as (i) Executive’s
violation of the restriction contained in Paragraph 10 of this Agreement, (ii) the loss or suspension by the State of Connecticut or by the Mohegan Tribal Gaming Commission of Executive’s license for Class III gaming for a period of thirty
(30) consecutive days, (iii) Executive’s conviction of any crime involving fraud, theft or moral turpitude, or (iv) Executive’s intentional or material breach of his obligations under this Agreement. Employer may suspend
Executive without pay upon Executive’s arrest for any alleged felony against the Employer or the Tribe. In the event that Executive is found not guilty or otherwise exonerated for an alleged crime against Employer or the Tribe,
Executive’s suspended pay shall be reimbursed to him. 
 Except in the event of suspension upon Executive’s arrest, if
Employer desires to terminate Executive for Cause, Employer shall give written notice specifying the act(s) claimed to constitute cause and specifying an effective date of termination, which date shall be no sooner than thirty (30) days after
the giving of such notice. Upon the written request of Executive, the Management Board of the Employer shall meet with Executive to discuss the reasons for 

  

 Page 4 of 9 

 
termination and to provide Executive with an opportunity to respond. Employer may, in its sole discretion, give Executive an opportunity to rectify the
reasons for termination. In the event Executive fails to rectify the act(s) claimed to constitute cause as set forth in the notice of termination, Executive’s employment with the Employer shall cease effective upon the date provided in the
notice of termination. If such termination is for Cause, then Executive shall not be entitled to any further compensation from and after the date of termination. 
 (D) Subject to the provisions of this paragraph, the Employer may terminate Executive’s employment other than for Cause, as defined above. In the event of termination other than for Cause, Executive shall be
paid, following termination, his Base Annual Salary, plus his Annual Bonus, from the date of termination to the expiration date of this Agreement (without regard to any renewal right after the date of termination); provided that such Base Annual
Salary and Annual Bonus shall be payable to Executive in the same amount and at the same intervals as would have been paid had his employment continued, and provided further that all payments of such Base Annual Salary and Annual Bonus shall be paid
to the Executive’s estate in the event of Executive’s death prior to the expiration date of this Agreement. 
 (E) In the event
that Executive voluntarily terminates his employment hereunder, Executive’s employment shall cease as of the date provided in Executive’s notice to Employer of his voluntary termination, and thereafter, provided that the Employer shall not
then be in material breach of this Agreement, Executive shall not be entitled to any further compensation hereunder. 
 10. Covenants
of Executive Not to Compete 
 Executive acknowledges that with respect to the Business, as defined above, and in the states of New
York, Connecticut, Massachusetts, Rhode Island, Vermont, New Hampshire and Maine (the “Restricted Area”) (i) the Employer is one of a limited number of entities engaged in the Business; (ii) his services to the Employer are
special and unique; (iii) his work for the Employer has given him and will continue to give him access to confidential information concerning the Employer; and (iv) he has the means to support himself and his dependents other than by
engaging in the Business of the Employer and the provisions of this Paragraph 10 will not impair such ability. Accordingly, in order to induce the Employer to enter into this Agreement, Executive covenants and agrees that: 
 (A) So long as Executive is employed by Employer and for a period of twelve (12) months following the voluntary or involuntary termination of his
employment (the “Restricted Period”), Executive shall not, in the Restricted Area, entertain or accept any offer of employment and shall not compete in any manner, either directly or indirectly, including, without limitation, as an
employee or independent contractor, investor, partner, shareholder, officer, director, principal, agent or trustee of any entity engaged in casino gaming, in the Restricted Area, without the express written approval of the Employer; provided,
however, that ownership of less than five percent (5%) of the shares of a publicly traded corporation engaged in casino gaming shall not be deemed to violate this paragraph. 
 (B) During the Restricted Period Executive shall not, directly or indirectly, hire or solicit any employee of the Employer or encourage any such employee
to leave such employment. 
  

 Page 5 of 9 

 11. Confidential Information 
 Executive agrees to receive Confidential Information (as hereinafter defined) of the Employer in confidence, and not to disclose to others, assist others
in the application of, or use for his own gain, such information, or any part thereof, unless and until it has become public knowledge, has come into the possession of such other or others by legal and equitable means, or if required to do so by
order of a court of competent jurisdiction. Executive further agrees that, upon termination of his employment with the Employer, all documents, records, notebooks and similar repositories of or containing Confidential Information, including copies
thereof, then in Executive’s possession, whether prepared by him or others, will be left with or returned to the Employer. For purposes of this Paragraph 11, “Confidential Information” means information disclosed to Executive or known
by Executive as a consequence of or arising from or out of his employment by the Employer, not generally known in the industry in which the Employer is or may become engaged about the Employer’s Business, products, processes and/or services.
Executive’s obligations under this Paragraph 11 shall survive any termination or expiration of this Agreement and Executive’s employment hereunder. 
 12. Rights and Remedies Upon Breach. 
 Executive acknowledges and agrees that a violation of
any provision of Paragraph 10 or 11 of this Agreement (the “Restrictive Covenants”) shall cause irreparable harm to the Employer, and the Employer shall be entitled to specific performance of this Agreement or an injunction without proof
of special damages, together with costs and attorney’s fees incurred by the Employer in enforcing its rights under this Agreement. If Executive breaches, or threatens to commit a breach of any of the Restrictive Covenants, the Employer shall
have the following rights and remedies, each of which rights and remedies shall be independent of the other and severally enforceable, and all of which rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies
available to the Employer under law or in equity: 
 (A) The right and remedy to have the Restrictive Covenants specifically enforced by any
court of competent jurisdiction including, without limitation, the right to entry against Executive of restraining orders and injunctions (preliminary, mandatory, temporary and permanent), without proof of special damages, against violations of such
covenants, threatened or actual, and whether or not then continuing, it being acknowledged and agreed that any such breach or threatened breach will cause irreparable injury to the Employer and that money damages will not provide an adequate remedy
to the Employer; and 
 (B) The right and remedy to require Executive to account for and pay over to the Employer all compensation, profits,
monies, accruals, increments or other benefits derived or received by Executive as the result of any transaction constituting a breach of the Restrictive Covenants. The Employer may set off any amounts due it under this Paragraph 12(B) against any
amounts owed to Executive under Paragraph 5, 6 or 9. 
 13. Notice 
 All notices hereunder shall be in writing. Any notice, request, information, legal process, or other instrument to be given or served hereunder by any
party to another shall be deemed given or served hereunder by any party to the other if either delivered personally or sent by prepaid 

  

 Page 6 of 9 

 
registered or certified mail, return receipt requested. Any such notice to the Employer shall be sent to the address set forth in the introductory paragraph
of this Agreement, to the attention of the Chief Executive Officer. Any such notice to Executive shall be sent to his residential address as set forth in the introductory paragraph of this Agreement. Either party may, through written notice to the
other party, change the address of notice as provided in this paragraph. 
 14. Entire Agreement; Modification 
 Except as otherwise provided herein, this Agreement supersedes and cancels any and all prior agreements between the parties hereto, express or implied,
relating to the subject matter hereof. This Agreement sets forth the entire agreement of the parties hereto with respect to the subject matter hereof. This Agreement may not be changed, modified, amended or altered except in a writing signed by both
parties. 
 15. Non-Waiver 
 The failure or refusal of either party to insist upon the strict performance of any provision of this Agreement or to exercise any right in any one or more instances or circumstances shall not be construed as a waiver or relinquishment of
such provision or right and shall in no way effect such provision or right, nor shall such failure or refusal be deemed a custom or practice contrary to such provision or right. 
 16. Severability 
 If any
paragraph, term or provision of this Agreement shall be held or determined to be unenforceable, the balance of this Agreement shall nevertheless continue in full force and effect and unaffected by such holding or determination. In addition, in any
such event, the parties agree that it is their intention and agreement that any such paragraph, term or provision which is held or determined to be unenforceable as written, shall nonetheless be enforced and binding to the fullest extent permitted
by law as though such paragraph, term or provision had been written in such a manner to such an extent as to be enforceable under the circumstances. Without limitation of the foregoing, with respect to any Restrictive Covenant contained herein, if
it is determined that any such provision is excessive as to duration or scope, it is intended that it nonetheless be enforced for such shorter duration or with such narrower scope as will render it enforceable. 
 17. Governing Law 
 This
Agreement shall be governed and construed in accordance with the laws of the State of Connecticut and the parties agree that, except as provided in Paragraph 20, only the federal and state courts located in the State of Connecticut shall have
jurisdiction to enforce the terms of this Agreement. 
 18. Limited Waiver of Sovereign Immunity 
 The Employer hereby waives its sovereign immunity from suit for claims by the Executive for the enforcement of this Agreement and any remedies for breach
thereof under Connecticut law. Nothing herein shall limit the Executive’s right to proceed with any claims otherwise allowed under the laws of the Mohegan Tribe of Indians of Connecticut. The 

  

 Page 7 of 9 

 
Employer hereby consents to personal jurisdiction and venue in any court of the State of Connecticut or any federal court sitting in the State of Connecticut
and the Mohegan Gaming Disputes Court and hereby waives any claim that it may have that such court is an inconvenient forum for the purposes of any proceeding arising under this Agreement as aforesaid and, with respect to a proceeding in a court of
the State of Connecticut or a federal court sitting in the State of Connecticut, any requirement that tribal remedies must be exhausted. 
 19. Dispute Resolution 
 Except as otherwise provided herein, whenever during the term of this Agreement, any
disagreement or dispute arises between the parties as to the interpretation of this Agreement or any rights or obligations arising hereunder, including the licensing of Executive by the Tribal Gaming Commission, such matters shall be resolved,
whenever possible, by meeting and conferring. Any party may request such a meeting by giving notice to the other, in which case such other party shall make itself available within seven (7) days thereafter. If such matters cannot be resolved
within ten (10) days after such meeting, either party may seek a resolution by binding arbitration in accordance with the then prevailing rules of the American Arbitration Association (or any successor thereto to the extent not inconsistent
herewith), upon notice to the other party of its intention to do so. The parties agree that in any such arbitration each party shall be entitled to discovery as provided by the Federal Rules of Civil Procedure. All hearings shall be conducted in
Hartford County, Connecticut within fifteen (15) days after the arbitrator is selected and shall be conducted in his or her presence. The decision of the arbitrator will be final and binding on the parties. The costs and expenses of the
arbitration shall be shared equally by the parties. 
 20. Gaming Disputes Court Jurisdiction 
 The parties agree that should any dispute arise under this Agreement or for the enforcement of the arbitration provisions in Paragraph 19, the Gaming
Disputes Court of the Mohegan Tribe of Indians shall be used as a forum only if a state or federal court denies jurisdiction, to (a) enforce the requirement that the parties submit disputes to arbitration as required by Paragraph 19, and
(b) enforce the arbitration decision as provided in Paragraph 19. 
 21. Headings 
 The headings of this Agreement are inserted for convenience only and shall not be considered in construction of the provisions hereof. 
 22. Assignment and Successors; Binding Effect 
 The rights and obligations of the Employer under this Agreement shall inure to the benefit of and shall be binding upon the successors of the Employer and may be assigned by the Employer, for all or any part of the
term hereof, provided that the Employer shall continue to be financially responsible to Executive hereunder. Executive shall have no right to assign, transfer, pledge or otherwise encumber any of the rights, nor to delegate any of the duties created
by this Agreement without prior written consent of the Employer. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Employer, its successors and assigns, and Executive, his heirs and legal representatives.

 Page 9 of 9Separation Agreement

 Exhibit 10.1 
 SEPARATION AGREEMENT 
 This Separation Agreement documents the agreement between Dr. Hunter
Jackson and NPS Pharmaceuticals, Inc., its subsidiaries and affiliates (“NPS” or “the Company”) concerning the termination of Dr. Jackson’s status as an employee of the Company effective the close of business on
May 11, 2006. 
 RECITALS 
  

	 	A.	Dr. Jackson has been employed by NPS as its Chief Executive Officer through and including the Separation Date. 

  

	 	B.	Dr. Jackson and NPS have entered into a number of agreements governing employment and severance of that employment including, but not limited to, the following:

  

	 	(i)	Employee Agreement Concerning Invention Assignment, Non-Disclosure and Non-Competition (“Non-Disclosure and Non-Competition Agreement”), a copy of which is attached as
Exhibit A. 

  

	 	(ii)	Agreement Providing Specified Benefits Following Termination of Employment Incident to Merger, Acquisition or Other Change of Control or Some Other Strategic Corporate Event
(“Termination Agreement”), a copy of which is attached as Exhibit B. 

  

	 	(iii)	Indemnity Agreement, a copy of which is attached as Exhibit C. 

  

	 	C.	Dr. Jackson and NPS have agreed to terminate Dr. Jackson’s employment under the Termination Agreement, and have concluded that he is entitled to receive the severance
benefits provided in paragraph 2 of the Termination Agreement. 

 Based on the foregoing Recitals, and on the mutual covenants
contained herein, Dr. Jackson and NPS agree as follows: 
 1. Separation Date. Dr. Jackson’s status as an employee with
NPS is terminated effective the close of business on May 11, 2006 (the “Separation Date”). Dr. Jackson’s resignation as an employee does not affect his status as a member of the Board of Directors of the Company. 

2. Severance and Benefits. The severance and benefits to which Dr. Jackson is entitled as of the Separation Date are as follows:

 2.1 Severance Pay. The Duration of Severance Period under said Termination Agreement is twenty-four months
including, but not limited to, the salary benefit as provided under paragraph 2.1 of the Termination Agreement. With respect to such salary benefits, the Company will pay to Dr. Jackson the sum of $1,020,000 U.S. as follows: 
 You will receive salary continuation for 24 months at your straight-time salary rate (“Base Pay”), less applicable withholding taxes. In
accordance with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), these payments will not commence until six months after your Separation Date. Accordingly, your first payment will
occur in December 2006 in the amount of seven months of Base Pay. The remaining payments will be made in a single lump sum as soon as administratively practicable following January 1, 2007. This payment schedule cannot be accelerated or
postponed by you or the Company. 

 2.2 Insurance. Dr. Jackson shall continue to receive the Company’s
standard medical and dental insurance benefits as long as he continues to serve as a member of the Board of Directors and is not employed by an entity which offers health and dental coverage, or until he becomes eligible for Medicare. Attached, as
Exhibit D, is language from the Company’s insurance underwriter regarding this coverage. At such time as Dr. Jackson retires from the Board of Directors of the Company, he will be eligible to elect to receive continued medical and dental
insurance coverage under the Consolidated Omnibus Budget Reconciliation Act (COBRA). The Company will pay the full premium amount due for medical and dental coverage under COBRA for 18 months, as allowed by the Termination Agreement, or until the
date Dr. Jackson first becomes eligible to obtain benefits from a subsequent employer, Medicare, or as otherwise provided by COBRA. 
 2.3 Stock Options. Effective on the first day after the Separation Date, all outstanding stock options, which would have vested during the next two years, will receive accelerated vesting, and all other
stock options will continue to vest at their normal rate and maintain their original expiration date, as long as Dr. Jackson maintains his continuous status as an employee, director, or consultant of the Company, as shown on Exhibit E.

 2.4 Restricted Stock Grant. As provided for in the Restricted Stock Award Agreement of January 5, 2004
(attached hereto as Exhibit F), effective on the first day after the Separation Date, as provided for in the Termination Agreement, any unvested shares will receive accelerated vesting. At that time, Dr. Jackson will be responsible to pay taxes
on the fair market value of the shares as of the date of acceleration. The amount of taxes due will be communicated to Dr. Jackson and Dr. Jackson will pay the taxes directly to the Company. 
 3. Confidential Information. The terms of the Non-Disclosure and Non-Competition Agreement will continue in effect after the Separation Date.
Under that agreement, Dr. Jackson is required to protect and not disclose any information regarding the Company’s proprietary intellectual property, its financial condition, terms of its business relations, and all other Confidential
Information as defined in that agreement. 
 4. Property. It is understood that anything produced by Dr. Jackson as an
employee of the Company is the property of the Company. Dr. Jackson is obligated to leave with or return to the Company any such documents whether tangible property or in electronic form belonging to the Company including, but not limited to,
documents or tangible property which may contain or reflect confidential information or trade secrets of the Company. Such confidential information and trade secrets may include scientific data, proprietary ideas, financial information, knowledge of
specific business dealings or practices, or other matters which the Company attempts to maintain as confidential in the course of its business. By his signature below, Dr. Jackson certifies to the Company that he has returned all property of
the Company. 
 5. 401(k) Plan. Dr. Jackson’s rights regarding his participation in the Company’s 401(k) Plan are
governed by the terms of the plan. 
 6. Life Insurance. The Company currently is the owner of a group term life insurance policy
that includes Dr. Jackson, which may be converted to an individual policy (with certain limitations). A conversion form will be provided by the insurance carrier to Dr. Jackson with benefits information. Any supplemental life insurance may
also be converted to an individual policy. 
 7. Personal Time Off (PTO). PTO will continue to be accrued through the Separation
Date and Dr. Jackson will be paid in cash for all unused PTO, up to twenty days. 
 8. Short- and Long-Term Disability
Insurance. All Company arrangements for payment, either direct or through insurance, for short-term disability and long-term disability, will cease on the Separation Date. 
 9. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law,
public policy or may subject Dr. Jackson to the payment of additional tax under Section 409A, all other conditions and provisions of this Agreement shall nevertheless remain in full force and 

 
effect so long as the economic or legal substance of the transaction contemplated hereby is not affected in any manner materially adverse to either party.
Upon such determination that any term or other provision is invalid, illegal, incapable of being enforced or may subject Dr. Jackson to the payment of additional tax under Section 409A, the parties shall negotiate in good faith to modify
this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible and, to the extent applicable, then do
not constitute nonqualified deferred compensation subject to the requirements of Section 409A or satisfy such requirements. NPS has advised Dr. Jackson to seek his own business and legal advice concerning the terms hereof. 
 10. Release. In consideration of receiving the benefits described herein, Dr. Jackson and all persons claiming by, through or under him,
hereby release and discharge NPS, its subsidiaries, affiliates, successors, assigns, agents, directors, officers, employees, representatives, attorneys and all other persons acting by, through, under or in concert with it (hereinafter collectively

 EMPLOYEE AGREEMENT CONCERNING 
 INVENTION ASSIGNMENT, NON-DISCLOSURE 
 AND NON-COMPETITION 
 Employee: HUNTER JACKSON 
 In consideration of employment or continued employment by NPS Pharmaceuticals, Inc. (which together with its affiliates and subsidiaries, if any, are hereinafter referred to as the “Company”), the compensation paid by the Company
from time to time and other good and valuable consideration, Employee hereby represents to and agrees with the Company as follows: 
  

	1.	Scope of Company’s Business Interests. 

  

	 	1.1	Employee understands that the Company is engaged in a continuous program of research, development, production, and marketing with respect to the discovery and development of novel
pharmaceutical therapies for a variety of diseases. 

  

	2.	Definitions. 

  

	 	2.1	“Confidential Information” shall mean: 

  

	 	2.1.1	any and all Intellectual Property or information whether business, financial, technical or otherwise, of any type whatsoever, in any form whatsoever, which is (a) proprietary
to the Company; or (b) submitted or disclosed to the Company by a third party.

	 	2.1.3	Confidential Information shall not include anything that is publicly known or generally employed by the trade at or after the effective date of this Agreement.

  

	 	2.2	“Intellectual Property” shall mean, without limitation, all copyrights, patents, trademarks, service marks, trade secrets, know-how and other rights commonly referred to
as “moral rights” and all intellectual property rights of any type whatsoever. 

  

	3.	Assignment of Rights in Intellectual Property. 

  

	 	3.1	Employee hereby assigns to the Company all of Employee’s rights in all discoveries, inventions and other technology, all works of authorship, all data and information, and all
Intellectual Property rights therein and thereto, which are made, discovered, developed, assembled, created, or conceived, in whole or in part, previously or hereafter by Employee: (a) during the course of and within the scope of employment
with the Company; or (b) with the aid of Confidential Information or the facilities, resources or property of the Company. 

  

	 	3.2	All of said Intellectual Property assigned to the Company shall be Confidential Information except for anything that is publicly known or generally employed by the trade, without
the fault of Employee, at or after the effective date of this Agreement. 

  

	 	3.3	Employee agrees to disclose promptly and fully to the Company anything which qualifies as Confidential Information hereunder. 

	4.	Confidential Information. 

  

	 	4.1	Employee understands that Confidential Information is confidential and secret and agrees to respect the confidentiality and secrecy of the same. Employee also understands that all
Confidential Information is the property of the Company or of a third party submitting the same to the Company. Employee agrees to treat Confidential Information submitted to the Company by third parties as if confidential and proprietary to the
Company. 

  

	 	4.2	Except as lawfully authorized or as may be required in the performance of Employee’s responsibilities for the Company, Employee: 

  

	 	4.2.1	agrees not to directly or indirectly disclose, reveal, report, publish, or transfer possession of, or access to, any Confidential Information to any person or entity;

  

	 	4.2.2	agrees, at the expense of the Company, promptly at all times hereafter to execute and deliver any and all acts and instruments as may be necessary or desirable to perfect and
protect the Company’s interest in the Confidential Information; and 

  

	 	4.2.3	agrees not to directly or indirectly use the Confidential Information except for the benefit of the Company in the performance of Employee’s responsibilities for the Company.

  

	5.	Trust Relationship. 

  

	 	5.1	Employee understands that employment with the Company creates a relationship of confidence and trust between the Employee and the Company with respect to the Employee’s care,
use, and treatment of Intellectual Property and Confidential Information of the Company. 

  

	6.	Delivery to the Company. 

  

	 	6.1	Employee agrees to turn over any and all Confidential Information in Employee’s possession or control upon request of the Company and upon termination of employment with the
Company. Employee understands and agrees that Employee’s obligations under this Agreement survive the termination of Employee’s employment with the Company. 

  

	7.	No Contract of Employment. 

  

	 	7.1	Nothing herein is intended to constitute a contract of employment or alter or change the terms of Employee’s understanding with the Company concerning terms and duration of
employment. 

  

	 	7.2	This Agreement is not an employment agreement and does not give the Employee the right to be employed by the Company in any capacity. The Company reserves the right to terminate
Employee’s employment at any time for any reason. 

  

	8.	Non-Competition. 

  

	 	8.1	The Employee and the Company agree that the Company’s activities, including its interests in Confidential Information and Intellectual Property, are of a proprietary, unique
and special nature and that if Employee’s services were used in competition with the Company, such use could cause serious and possibly irreparable harm to the Company. Accordingly, Employee agrees to the commitments of non-competitive
activities as described herein. 

  

	 	8.1.1	Employee agrees that during the period of employment with the Company, Employee shall not directly or indirectly engage in any employment or activity (other than for the Company)
which competes with the business of the Company as now or hereinafter conducted. 

	 	8.1.2	Employee agrees that during the period of employment with the Company, and for a period of one year thereafter, Employee shall not directly or indirectly (a) call on, solicit,
take away, or attempt to take away for the benefit of Employee or of any other person or entity, any customer, supplier, or client of the Company with whom Employee became acquainted during employment with the Company, or (b) solicit, take
away, or attempt to take away, for the benefit of the Employee or of any other person or entity, any employee or officer of the Company. 

  

	 	8.1.3	Employee agrees that upon termination of employment with the Company, Employee shall not accept any position with another Company or engage directly or indirectly in any other
activity in which Employee would clearly use or disclose material Confidential Information of the Company. 

  

	9.	No Use of Other’s Intellectual Property. 

  

	 	9.1	Employee represents to the Company that Employee has not brought and has not used, and agrees that it will not bring to the Company and will not use in the performance of any
responsibilities for the Company, any information, materials or the like which are confidential and are proprietary to a former employer or to some other person or entity without written authorization from said former employer, person or entity.

  

	10.	Injunctive Relief. 

  

	 	10.1	Employee agrees that, because of the unique nature of this Agreement and the obligations of Employee regarding non-disclosure, non-use and assignment of inventions and Intellectual
Property, monetary damages alone will be an inadequate remedy for Employee’s breach of such obligations. As a result, Employee agrees that the Company shall be entitled to obtain injunctive and other equitable relief to protect the confidential
nature of its Confidential Information and its interest in such inventions and Intellectual Property, in addition to all other remedies which may be available at law or otherwise. 

  

	11.	Miscellaneous. 

  

	 	11.1	If any provision of this Agreement is determined by a court of competent jurisdiction to be invalid or unenforceable, the same shall be deemed severed from the remainder of this
Agreement and shall not cause the invalidity or unenforceability of the remainder of this Agreement. 

  

	 	11.2	This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors, beneficiaries or legatees. 

  

	 	11.3	This Agreement shall be governed by the laws of the State of Utah without reference to the conflicts of law principles thereof. 

  

	 	11.4	This Agreement constitutes the final, complete, and exclusive agreement between the Company and Employee concerning the subject matter of this Agreement and supersedes all prior
representations, agreements, understandings, negotiations and discussions, written or oral, between the Company and Employee with respect thereto. In the event Employee and the Company have previously entered into an agreement concerning the subject
matter hereof, this Agreement is considered a novation of that agreement. Employee agrees that all Confidential Information received by Employee prior to the “Date of Hire” shown below is governed hereby and is deemed received pursuant to
the terms hereof. Any inventions excluded by Employee thereunder are also deemed excluded hereunder unless stated otherwise in Exhibit A hereof. Any modification, recision or amendment of this Agreement shall not be effective unless made in writing
and executed by both parties. 

	 	11.5	Employee has identified in the space below all inventions, ideas, biological compounds, cell lines, and other items of Intellectual Property of interest to the Company as described
herein, and other items of Intellectual Property which have been made or conceived or first reduced to practice by Employee, alone or jointly with others, PRIOR to employment with the Company AND which Employee desires to exclude from the operation
of this Agreement. Employee claims an interest in the following PRIOR items of Intellectual Property: 

                                       
                                        
                                        
                                        
                                        
                                
                                       
                                        
                                        
                                        
                                        
                                
                                       
                                        
                                        
                                        
                                        
                                
 If no inventions, ideas, discoveries or other items of Intellectual Property are identified in the space above, then Employee represents that there are no
such inventions, ideas, discoveries or other items of Intellectual Property. 
  

	 	11.6	Employee agrees that adequate consideration to the Employee from the Company can be found in each of the following: 

  

	 	11.6.1 	continued employment with the Company; 

  

	 	11.6.2 	compensation paid to the Employee by the Company from time to time; and 

  

	 	11.6.3 	capital stock of the Company sold or granted to the Employee from time to time. 

  

	 	11.7	Employee acknowledges that his or her employment with the Company was expressly conditioned upon an understanding that an agreement covering the subject hereof was a condition of
employment and that this Agreement is the intended agreement and that if signed after the Date of Hire the Agreement is intended to relate back to the Employee’s Date of Hire and to be part of the terms of initial employment.

 WHEREAS, the Executive has been hired into or otherwise designated a member of the Company’s “Leadership Corps” due to his/her serving as
an officer, professional, or other senior executive of the Company; and 
 WHEREAS, the Company has previously adopted and currently
maintains, for the benefit of the Leadership Corps, a Severance Pay Plan (the “Plan”), a copy of which is attached hereto and incorporated by reference, which provides for certain post-employment benefits as specified therein; and

 WHEREAS, in furtherance of the purposes of the Plan and as further assurances to the Executive, the Company’s Board of Directors and
its Compensation Committee have previously determined that it is desirable and in the best interest of the Company, its shareholders, and other constituencies to execute this Agreement providing the Executive with specified benefits following
termination of Executive’s employment with the Company incident to a merger, acquisition or other form of a Change in Control or incident to some other Strategic Corporate Event or as otherwise set forth herein; 
 NOW THEREFORE, in consideration of one dollar and other good and valuable consideration, receipt and sufficiency whereof are hereby acknowledged, the
Company and Executive hereby agree as follows: 
 1. Termination of Employment. A covered termination of employment may occur hereunder as
follows: 
  

	 	1.1	Change in Control. If at any time within the Executive’s Determination Period (shown above) following a Change in Control (i) the Executive terminates his or
her employment with the Company (or any parent or subsidiary of the Company) for Good Reason, or (ii) the Company (or any parent or subsidiary of the Company) terminates Executive’s employment for other than Cause, death or permanent
disability, then the Company shall pay and provide to the Executive the specified Severance Benefit provided herein for the Severance Period (shown above). 

  

	 	1.2	 Strategic Corporate Event. If at any time within the Executive’s Determination Period, following a Strategic Corporate Event, as defined herein,
the Executive voluntarily implements a termination of his/her employment for Good Reason then the Company shall pay and provide to the Executive the specified Severance Benefit provided herein for the Severance Period. The Determination 

	 	 
Period for this purpose shall begin on the first date when the job prospects for the Executive have been materially altered as a result of such Strategic
Corporate Event. 

  

	 	1.3	Other. If at any time (i) Executive terminates his employment with Company (or any parent or subsidiary of Company) for Good Reason (as defined in Para. 2.10 of the
attached Plan), or (ii) Company (or any parent or subsidiary of Company) terminates Executive’s employment for other than Cause (as defined in Para. 2.4 of the attached Plan), then Executive shall receive as severance compensation for the
Severance Period his salary and other items of value as set forth in Paragraphs 2.1, 2.2, and 2.3 of this Agreement (a) regardless of whether a Change of Control or a Strategic Corporate Event is deemed to exist; (b) regardless of whether
Executive is deemed a Covered Employee under the Plan; and (c) regardless of whether the Plan is in effect, has been changed, or if the Plan otherwise fails to provide for Executive a severance compensation at least equal to the severance
compensation as set forth in Paragraphs 2.1, 2.2, and 2.3 of this Agreement. In the event that any conflict or ambiguity arises between the provisions of this Paragraph 1.3 and the provisions of the Plan, any other part of this Agreement, or any
other document, then the provisions of this Paragraph 1.3 shall supersede and control. 

 2. Severance Benefits. Upon
termination of an Executive’s employment due to a Change in Control or Strategic Corporate Event, during the Executive’s Determination Period, or as otherwise set forth in this Agreement, Executive will become entitled to the following
Severance Benefits for his/her Severance Period as follows: 
  

	 	2.1	Salary. The Company will continue to pay Executive his or her annual Base Pay (less applicable withholding taxes), as in effect immediately prior to the date of
termination, to be paid periodically in accordance with the Company’s normal payroll policies, or (ii) on mutual agreement of the Company and Executive, Executive shall be paid the aggregate of such pay in a lump sum single payment to be
made within the first 90 days of termination. Payments will not be terminated early or reduced in the event of death, disability or reemployment of the Executive prior to receipt of the full amount of this benefit. 

  

	 	2.2	Insurance. If Executive, and any spouse and/or dependents of Executive (“Family Members”) has/have medical and/or dental coverage on the date of
Executive’s termination of employment under a group health plan sponsored by the Company, the Company will reimburse Executive for the total applicable premium cost for medical and dental coverage under the Consolidated Omnibus Budget
Reconciliation Act of 1986, 29 U.S.C. Sections 1161-1168; 26 U.S.C. Section 4980B(f), as amended, and all applicable regulations (referred to collectively as “COBRA”) for Executive and Family Members for the Determination Period (to
the extent COBRA coverage lasts for the full term); provided, that the Company shall have no obligation to reimburse Executive for the premium cost of COBRA coverage beginning on or after the date Executive and Family Members first become eligible
to obtain comparable benefits from a subsequent employer. 

  

	 	2.3	Stock Options. Effective on the first day of the Executive’s Severance Period, the Executive’s existing stock options will receive accelerated vesting for the
longer of (i) the period ending on the last day of the Executive’s Severance Period, or (ii) such other period as the Executive may be entitled under any stock option plan or grant or retirement plan or other provision of any
applicable Company practice. The Executive will have the right to exercise all stock options previously vested or vested hereunder beginning of the first day of the Executive’s Severance Period and continuing for the longer of (i) the
duration of the Executive’s Severance Period, or (ii) such other period as the Executive may be entitled under any stock option plan or grant or retirement plan or other provision of any applicable Company policy or practice.
Notwithstanding the foregoing, the Executive will be required to abide by the terms of any existing “lock-up” agreement to which he/she is a party and by the applicable terms of the Company’s Insider Trading Policy for the period of
time otherwise required, and all applicable securities law and regulations. 

 3. Stipulation. The Executive hereby agrees and
stipulates that except as specified in this Agreement, the terms of employment of the Executive remain as they were before this Agreement was executed and 

	 	 
acknowledges that this Agreement is not the entire statement of the terms of employment of the Executive but rather constitutes the entire and sole agreement
for the subject matter addressed herein. 

 4. Interpretation and Definitions. 
  

	 	4.1	Interpretation. The provisions of this Agreement are intended to advance the purposes of the Plan and except to the extent any provision hereof supersedes or conflicts
with a provision of the Plan, this Agreement and the Plan should be interpreted so has to make them harmonious. 

  

	 	4.2	Incorporation of the Plan in this Agreement. To the extent applicable to the Executive, the Plan is incorporated herein and made a part hereof. 

 

	 	4.3	Definitions. Capitalized terms used herein that are not defined herein have the meaning given in the Plan, unless the context specifies otherwise.

 5. Severability. In case any of the provisions contained in this Agreement shall for any reason be held to be invalid, illegal
or unenforceable in any respect, any such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid, illegal or unenforceable provision had been
limited or modified (consistent with its general intent) to the extent necessary to make it valid, legal and enforceable, or if it shall not be possible to so limit or modify such invalid, illegal or unenforceable provision or part of a provision,
this Agreement shall be construed as if such invalid, illegal or unenforceable provision or part of a provision had never been contained in this Agreement. 
 6. Amendment. This Agreement shall not be amended, modified or discharged in whole or in part except in writing signed by both of the parties hereto. The failure of either of the parties to require the performance of a term or
obligation or to exercise any right under this Agreement or the waiver of any breach hereunder shall not prevent subsequent enforcement of such term or obligation or exercise of such right or the enforcement at any time of any other right hereunder
or be deemed a waiver of any subsequent breach of the provision so breached, or of any other breach hereunder. 
 7. Successors and Assigns. This
Agreement shall inure to the benefit of (i) successors of the Company by way of merger, consolidation or transfer of all or substantially all of the assets of the Company and may not be assigned by Executive; and (ii) the heirs, executors,
administrators, legal representatives and successors of Executive. 
 8. Entire Agreement. This Agreement constitutes the entire agreement
between the parties concerning the subjects hereof and supersedes all prior understandings and agreements between the parties relating to the subject matter hereof. 
 9. Governing Law. This Agreement shall be construed and regulated in all respects under the laws of the State or Province where Executive is domiciled on the date hereof. 
 10. Counterparts. This Agreement may be executed in counterparts, each of which when so executed and delivered shall be taken to be an original, but such
counterparts shall together constitute one and the same document. 
 11. Examples of Change in Control and Other Strategic Corporate Events. By
way of illustration and not limitation, provided below are examples to aid in the interpretation of this Agreement. 
  

	 	11.1.	Change in Control. Many circumstances that constitute a Change in Control are provided in the Plan. The Compensation Committee of the Board of Directors may declare
other circumstances, from time to time. 

	 	11.2	Strategic Corporate Event. A Strategic Corporate Event occurs, in general when an individual Executive’s job prospects within the Company are materially altered
without Cause. Circumstances that constitute a Strategic Corporate Event leading to a material alteration in the Executive’s job prospects must be determined on a case-by-case basis. Such an event may occur for this Executive and not for
another executive who has signed a similar severance agreement with the Company and vice-versa. For example, if the Company signs a major product out-license agreement, that event by its terms might constitute a Strategic Corporate Event if it
resulted in a material alteration of another executive’s job prospects (given other circumstances) and not for this Executive or vice-versa. Also, the failure in the clinic of one or more late stage programs might constitute a Strategic
Corporate Event for this Executive (given relevant circumstances) and a concomitant alteration in this Executive’s job prospects while not constituting a Strategic Corporate Event and not producing a concomitant alteration in the job prospects
for another executive and vice-versa. Additionally, a substantial acquisition for cash (with attendant properties and personnel) might cause a re-alignment of duties of senior personnel in a way that caused a material alteration in the job prospects
of this Executive (given relevant circumstances) thus constituting a Strategic Corporate Event for this Executive and not for another executive and vice-versa. In circumstances where doubt or uncertainties attend for this Executive, about the
occurrence of a Strategic Corporate Event and the required attendant material alteration in this Executive’s job prospects, the Executive and the Company expect that discussion and evaluation will usually bring required clarity and agreement.
Where such is not timely obtained, the Company or the Executive may petition the Compensation Committee of the Board of Directors by written correspondence directed to the Chairman of the Committee to resolve any difference. Alternatively, the
Executive may use the claims procedure under the Plan. 

 12. Indemnity. Indemnity is the subject of a separate agreement between the
Company and the Executive executed on or about the date of hire. 
 IN WITNESS WHEREOF, the parties have executed this Agreement, effective
the Effective Date shown above.

acceleration of vesting upon a Change in Control as defined above are found in the Company’s Employee Stock Option Plans in effect on February 19, 2003 and options previously granted thereunder and then outstanding. Those Stock Option

employees generally and for Covered Employees in particular. 
 4.2 Release. As a condition to receiving Severance
Benefits under this Plan, each Covered Employee will be required to sign a waiver and release of all claims arising out of his or her Involuntary Termination and employment with the Company and its subsidiaries and affiliates, in a form satisfactory
to the General Counsel of the Company. 
 5. Vacation Days. Any unused vacation pay accrued as of a Covered Employee’s date of
Involuntary Termination will be paid at the time the Covered Employee receives his or her first Severance Benefit. No Covered Employee may use any accrued but unused vacation pay to extend his or her Involuntary Termination date or to postpone or
delay the start of his or her Severance Period. 
 6. Withholding. The Company will withhold from any Severance Benefit all federal,
state, local and other taxes required to be withheld therefrom and any other required payroll deductions. 
 7. Administration. The
Company is the administrator of the Plan (within the meaning of section 3(16)(A) of ERISA). The Plan will be administered and interpreted by the Administrator (in his or her sole discretion). The Administrator is the “named fiduciary” of
the Plan for purposes of ERISA and will be subject to the fiduciary standards of ERISA when acting in such capacity. Any decision made or other action taken by the Administrator with respect to the Plan, and any interpretation by the Administrator
of any term or condition of the Plan, or any related document, will be conclusive and binding on all persons and be given the maximum possible deference allowed by law. The Administrator has the authority to act for the Company (in a non-fiduciary
capacity) as to any matter pertaining to the Plan; provided, however, that this authority does not apply with respect to (a) the Company’s power to amend or terminate the Plan or (b) any action that could reasonably be expected
to increase significantly the cost of the Plan is subject to the prior approval of the senior officer of NPS Pharmaceuticals, Inc. The Administrator may delegate in writing to any other person all or any portion of his or her authority or
responsibility with respect to the Plan. 
 8. Eligibility to Participate. The Administrator will not be excluded from participating
in the Plan if otherwise eligible, but he or she is not entitled to act or pass upon any matters pertaining specifically to his or her own benefit or eligibility under the Plan. The senior officer of NPS Pharmaceuticals, Inc. will act upon any
matters pertaining specifically to the benefit or eligibility of the Administrator under the Plan. 
 9. Amendment or Termination. The
Company reserves the right to amend or modify the Plan at any time, without advance notice to any Covered Employee. Notwithstanding the preceding, no amendment or modification of the Plan shall impair the rights of any Covered Employee, unless
mutually agreed otherwise between the Covered Employee and the Company, which agreement must be in writing and signed by the Covered Employee and the Company. The Plan will automatically terminate on March 31, 2008 unless the Company determines
otherwise; provided, however, if there are any outstanding Determination Period or Severance Period on March 31, 2008, then the Plan will remain in effect until all Severance Benefits have been paid with respect to any such Determination
Periods and Severance Periods. The Company shall not have the power to terminate the Plan prior to March 31, 2008 without the consent of the affected Covered Employees. 
 10. Claims Procedure. Any employee or other person who believes he or she is entitled to any payment under the Plan may submit a claim in writing
to the Administrator. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Plan on which the denial is based. The notice
will also describe any additional information needed to support the claim. The denial notice will be provided within 90 days after the claim is received. If special 

 
circumstances require an extension of time (up to 90 days), written notice of the extension will be given within the initial 90-day period. 

11. Appeal Procedure. If the claimant’s claim is denied, the claimant (or his or her authorized representative) may apply in writing to
the Administrator for a review of the decision denying the claim. Review must be requested within 60 days following the date the claimant received the written notice of their claim denial or else the claimant loses the right to review. The claimant
(or representative) then has the right to review pertinent documents and to submit issues and comments in writing. The Administrator will provide written notice of his or her decision on review within 60 days after it receives a review request.
If additional time (up to 60 days) is needed to review the request, the claimant (or representative) will be given written notice of the reason for the delay. 
 12. Source of Payments. All Severance Benefits will be paid in cash from the general funds of the Company; no separate fund will be established under the Plan; and the Plan will have no assets. No right of any
person to receive any payment under the Plan will be any greater than the right of any other general unsecured creditor of the Company. 
 13. Inalienability. In no event may any current or former employee of the Company or any of its subsidiaries or affiliates sell, transfer, anticipate, assign or otherwise dispose of any right or interest under the Plan. At no time
will any such right or interest be subject to the claims of creditors nor liable to attachment, execution or other legal process. 
 14.
No Enlargement of Employment Rights. Neither the establishment or maintenance of the Plan, any amendment of the Plan, nor the making of any benefit payment hereunder, will be construed to confer upon any individual any right to be continued
as an employee of the Company. The Company expressly reserves the right to discharge any of its employees at any time, with or without cause. 
 15. Applicable Law. The provisions of the Plan will be construed, administered and enforced in accordance with ERISA and, to the extent applicable, the laws of the State of Utah. 
 16. Severability. If any provision of the Plan is held invalid or unenforceable, its invalidity or unenforceability will not affect any other
provision of the Plan, and the Plan will be construed and enforced as if such provision had not been included. 
 17. Headings.
Headings in this Plan document are for purposes of reference only and will not limit or otherwise affect the meaning hereof. 
 18.
Indemnification. The Company hereby agrees to indemnify and hold harmless the officers and employees of the Company, and the members of its boards of directors, from all losses, claims, costs or other liabilities arising from their acts or
omissions in connection with the administration, amendment or termination of the Plan, to the maximum extent permitted by applicable law. This indemnity will cover all such liabilities, including judgments, settlements and costs of defense. The
Company will provide this indemnity from its own funds to the extent that insurance does not cover such liabilities. This indemnity is in addition to and not in lieu of any other indemnity provided to such person by the Company. 
 19. Additional Information.

 20. Statement of ERISA Rights. As a Covered Employee under the Plan, you have certain
rights and protections under ERISA: 
 (a) You may examine (without charge) all Plan documents, including any amendments and
copies of all documents filed with the U.S. Department of Labor, such as the Plan’s annual report (IRS Form 5500). These documents are available for your review in the Company’s Human Resources Department. 
 (b) You may obtain copies of all Plan documents and other Plan information upon written request to the Plan Administrator. A reasonable
charge may be made for such copies. 
 In addition to creating rights for Covered Employees, ERISA imposes duties upon the people who are
responsible for the operation of the Plan. The people who operate the Plan (called “fiduciaries”) have a duty to do so prudently and in the interests of you and the other Covered Employees. No one, including the Company or any other
person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a benefit under the Plan or exercising your rights under ERISA. If your claim for a severance benefit is denied, in whole or in part, you must
receive a written explanation of the reason for the denial. You have the right to have the denial of your claim reviewed. (The claim review procedure is explained in Sections 10 and 11 above.) 
 Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request materials and do not receive them within
30 days, you may file suit in a federal court. In such a case, the court may require the Plan Administrator to provide the materials and to pay you up to $110 a day until you receive the materials, unless the materials were not sent because of
reasons beyond the control of the Plan Administrator. If you have a claim that is denied or ignored, in whole or in part, you may file suit in a state or federal court. If it should happen that you are discriminated against for asserting your
rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a federal court. 
 In any case, the court will
decide who will pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds that your
claim is frivolous. 
 If you have any questions regarding the Plan, please consult the Company’s Human Resources Department. If you
have any questions about this statement or about your rights under ERISA, you may contact the nearest area office of the Employee Benefits Security Administration (formerly the Pension and Welfare Benefits Administration), U.S. Department of Labor,
listed in your telephone director, or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue, N.W. Washington, D.C. 20210. 

 Exhibit C 
 to the 
 SEPARATION AGREEMENT 
 between 
 Hunter Jackson 
 and 
 NPS Pharmaceuticals, Inc.

  

 Indemnification Agreement 

 INDEMNITY AGREEMENT 
 THIS AGREEMENT is made and entered into this 17th day of February, 1994 by and between NPS Pharmaceuticals, Inc., a Delaware corporation (the “Corporation”), and Hunter Jackson, Ph.D. (“Agent”).

 RECITALS 
 WHEREAS, Agent
performs a valuable service to the Corporation in the capacity as a director and/or officer of the Corporation; 
 WHEREAS, the stockholders
of the Corporation have adopted bylaws (the “Bylaws”) providing for the indemnification of the directors, officers, employees and other agents of the Corporation, including persons serving at the request of the Corporation in such
capacities with other corporations or enterprises, as authorized by the Delaware General Corporation Law, as amended (the “Code”); 
 WHEREAS, the Bylaws and the Code, by their non-exclusive nature, permit contracts between the Corporation and its agents, officers, employees and other agents with respect to indemnification of such persons; and 
 WHEREAS, in order to induce Agent to continue to serve as an officer and/or director of the Corporation, the Corporation has determined and agreed to
enter into this Agreement with Agent; 
 NOW, THEREFORE, in consideration of Agent’s continued service as an officer and/or director
after the date hereof, the parties hereto agree as follows: 
 AGREEMENT 
 1. Services to the Corporation. Agent will serve, at the will of the Corporation or under separate contract, if any such contract exists, as an
officer and/or director of the Corporation or as a director, officer or other fiduciary of an affiliate of the Corporation (including any employee benefit plan of the Corporation) faithfully and to the best of his ability so long as he is duly
elected and qualified or appointed in accordance with the provisions of the Bylaws or other applicable charter documents of the Corporation or such affiliate; provided, however, that Agent may at any time and for any reason resign from such position
(subject to any contractual obligation that Agent may have assumed apart from this Agreement) and that the Corporation or any affiliate shall have no obligation under this Agreement to continue Agent in any such position. 
 2. Indemnity of Agent. The Corporation hereby agrees to hold harmless and indemnify Agent to the fullest extent authorized or permitted by the
provisions of the Bylaws, the Code, and applicable law as the same may be amended from time to time (but, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than the Bylaws, the Code, or
applicable law permitted prior to adoption of such amendment). 
 3. Additional Indemnity. In addition to and not in limitation of the
indemnification otherwise provided for herein, and subject only to the exclusions set forth in Section 4 hereof, the Corporation hereby further agrees to hold harmless and indemnify Agent: 
 (a) against any and all expenses (including attorneys’ fees), witness fees, damages, judgments, fines and amounts paid in settlement
and any other amounts that Agent becomes legally obligated to pay because of any claim or claims made against or by him in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative (including an action by or in the right of the Corporation) to which Agent is, was or at any time becomes a party, or is threatened to be made a party, by reason of the fact that Agent is, was or at any time becomes a
director, officer, employee or other agent of Corporation, or is or was serving or at any time serves at the request of the Corporation as a director, officer, employee or other agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise; and 

 (b) otherwise to the fullest extent as may be provided to Agent by the Corporation under
the non-exclusivity provisions of the Code and Section 11.5 of the Bylaws. 
 4. Limitations on Additional Indemnity. No
indemnity shall be paid by the Corporation under this agreement: 
 (a) on account of any claim against Agent for an
accounting of profits made from the purchase or sale by Agent of securities of the Corporation pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or similar provisions of any federal, state
or local statutory law; 
 (b) on account of Agent’s conduct that was knowingly fraudulent or deliberately dishonest or
that constituted willful misconduct; 
 (c) on account of Agent’s conduct that constituted a breach of Agent’s duty
of loyalty to the Corporation or resulted in any personal profit or advantage to which Agent was not legally entitled; 
 (d)
for which payment is actually made to Agent under a valid and collectible insurance policy or under a valid and enforceable indemnity clause, bylaw or agreement, except in respect of any excess beyond payment under such insurance, clause, bylaw or
agreement; 
 (e) if indemnification is not lawful (and, in this respect, both the Corporation and Agent have been advised
that the Securities and Exchange Commission believes that indemnification for liabilities arising under the federal securities laws is against public policy and is, therefore, unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication); or 
 (f) in connection with any proceeding (or part thereof) initiated by Agent, or any
proceeding by Agent against the Corporation or its directors, officers, employees or other agents, unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized by the Board of Directors of the
Corporation, (iii) such indemnification is provided by the Corporation, in its sole discretion, pursuant to the powers vested in the Corporation under the Code, or (iv) the proceeding is initiated pursuant to Section 9 hereof.

 5. Continuation of Indemnity. All agreements and obligations of the Corporation contained herein shall continue during the period
Agent is a director, officer, employee or other agent of the Corporation (or is or was serving at the request of the Corporation as a director, officer, employee or other agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as Agent shall be subject to any possible claim or threatened, pending or completed action, suit or proceeding, whether civil, criminal, arbitrational, administrative or
investigative, by reason of the fact that Agent was serving in the capacity referred to herein. 
 6. Partial Indemnification. Agent
shall be entitled under this Agreement to indemnification by the Corporation for a portion of the expenses (including attorneys’ fees), witness fees, damages, judgments, fines and amounts paid in settlement and any other amounts that Agent
becomes legally obligated to pay in connection with any action, suit or proceeding referred to in Section 3 hereof even if not entitled hereunder to indemnification for the total amount thereof, and the Corporation shall indemnify Agent for the
portion thereof to which Agent is entitled. 
 7. Notification and Defense of Claim. Not later than thirty (30) days after
receipt by Agent of notice of the commencement of any action, suit or proceeding, Agent will, if a claim in respect thereof is to be made against the Corporation under this Agreement, notify the Corporation or confirm that the Corporation has notice
of the commencement thereof; but the omission so to notify or so to confirm notice to the Corporation will not relieve it from any liability which it may have to Agent otherwise than under this Agreement. With respect to any such action, suit or
proceeding as to which Agent notifies the Corporation of the commencement thereof or confirms that the Corporation has such notice: 
 (a) the Corporation will be entitled to participate therein at its own expense; 

 (b) except as otherwise provided below, the Corporation may, at its option and jointly
with any other indemnifying party similarly notified and electing to assume such defense, assume the defense thereof, with counsel reasonably satisfactory to Agent. After notice from the Corporation to Agent of its election to assume the defense
thereof, the Corporation will not be liable to Agent under this Agreement for any legal or other expenses subsequently incurred by Agent in connection with the defense thereof except for reasonable costs of investigation or otherwise as provided
below. Agent shall have the right to employ separate counsel in such action, suit or proceeding but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of
Agent unless (i) the employment of counsel by Agent has been authorized by the Corporation, (ii) Agent shall have reasonably concluded that there may be a conflict of interest between the Corporation (or any other agent or agents for whom
the Corporation has assumed or may assume the defense) and Agent in the conduct of the defense of such action or (iii) the Corporation shall not in fact have employed counsel to assume the defense of such action, in each of which cases the fees
and expenses of Agent’s separate counsel shall be at the expense of the Corporation. The Corporation shall not be entitled to assume the defense of any action, suit or proceeding brought by or on behalf of the Corporation or as to which Agent
shall have made the conclusion provided for in clause (ii) above; and 
 (c) the Corporation shall not be liable to
indemnify Agent under this Agreement for any amounts paid in settlement of any action or claim effected without its written consent, which shall not be unreasonably withheld. The Corporation shall be permitted to settle any action except that it
shall not settle any action or claim in any manner which would impose any penalty or limitation on Agent without Agent’s written consent, which may be given or withheld in Agent’s sole discretion. 
 8. Expenses. Promptly following request for advancement of expenses and upon receipt of an undertaking by or on behalf of Agent to repay said
amounts on the terms hereof, the Corporation shall advance, prior to the final disposition of any proceeding, all expenses actually and reasonably incurred by Agent in connection with such proceeding, prior to the date (if at all) when the
Corporation has determined that such Agent has acted in bad faith or in a manner that the Agent did not believe to be in or not opposed to the best interests of the Corporation, that such Agent is not entitled to indemnification due to exclusion
under Section 4 hereof or, with respect to any criminal action or proceeding that such Agent acted without reasonable cause to believe that his conduct was lawful. Such determination may be made by the Corporation upon a finding that the facts
known to the decision-making party at the time such determination is made, clearly and convincingly support such a determination. Such determination may be made by the Corporation (i) as to an officer by a vote of all disinterested directors
provided such directors constitute a quorum of the Board of Directors; or (ii) (if such a quorum is not obtainable, or even if obtainable) upon direction of a majority of the disinterested directors as to an officer or director by independent
legal counsel (selected by said majority, or other representation of the Corporation, from a panel of five alternates approved for this purpose by the National Association of Corporate Directors) in a written opinion. This provision is adopted under
and is to be interpreted consistent with Delaware Code §145(f) and Bylaw 11.5. 
 9. Enforcement. 
 (a) Any right to indemnification or advances granted by this Agreement to Agent shall be enforceable by or on behalf of Agent in any court
of competent jurisdiction if (i) the claim for indemnification or advances is denied, in whole or in part, or (ii) no disposition of such claim is made within ninety (90) days of request therefor. Agent, in such enforcement action, if
successful in whole or in part, shall be entitled to be paid also the expense of prosecuting his claim. It shall be a defense to any action for which a claim for indemnification is made under Section 3 hereof (other than an action brought to
enforce a claim for expenses pursuant to Section 8 hereof, provided that the required undertaking has been tendered to the Corporation) that Agent is not entitled to indemnification because of the limitations set forth in Section 4 hereof.
Neither the failure of the Corporation (including its Board of Directors or its stockholders) to have made a determination prior to the commencement of such enforcement action that indemnification of Agent is proper in the circumstances, nor an
actual determination by the Corporation (including its Board of Directors or its stockholders) that such indemnification is improper shall be a defense to the action or create a presumption that Agent is not entitled to indemnification under this
Agreement or otherwise. 

 (b) Any determination, election, or authorization (a “Determination”) permitted
or required herein to be made by the Corporation when made by the Board of Directors, shall be made in the manner set out in the following sentence when the Determination is (i) to authorize the Agent to initiate a proceeding against the
Corporation under paragraph 4(f) hereof, (ii) to participate in a proceeding under paragraph 7(a) hereof, or (iii) to assume the defense under paragraph 7(b) hereof. A Determination made by the Board of Directors under the proceeding
sentence shall require only a quorum of one-third of the exact number of directors of the Corporation fixed from time to time in accordance with the Certificate of Incorporation if such Determination is to authorize the Agent to bring an action
under (i) above, to cause the Corporation to participate in a proceeding under (ii) above and/or to assume a defense of an action against the Agent under (iii) above. 
 10. Subrogation. In the event of payment under this Agreement, the Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Agent, who shall execute all documents required and shall do all acts that may be necessary to secure such rights and to enable the Corporation effectively to bring suit to enforce such rights. 
 11. Non-Exclusivity of Rights. The rights conferred on Agent by this Agreement shall not be exclusive of any other right which Agent may have or
hereafter acquire under any statute, provision of the Corporation’s Certificate of Incorporation or Bylaws, agreement, vote of stockholders or directors, applicable law or otherwise, both as to action in his official capacity and as to action
in another capacity while holding office. 
 12. Survival of Rights. 
 (a) The rights conferred on Agent by this Agreement shall continue after Agent has ceased to be a director, officer, employee or other
agent of the Corporation or to serve at the request of the Corporation as a director, officer, employee or other agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise and shall inure to the
benefit of Agent’s heirs, executors and administrators. 
 (b) The Corporation shall require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporation, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the
Corporation would be required to perform if no such succession had taken place. 
 13. Separability. Each of the provisions of this
Agreement is a separate and distinct agreement and independent of the others, so that if any provision hereof shall be held to be invalid for any reason, such invalidity or unenforceability shall not affect the validity or enforceability of the
other provisions hereof. Furthermore, if this Agreement shall be invalidated in its entirety on any ground, then the Corporation shall nevertheless indemnify Agent to the fullest extent provided by the Bylaws, the Code or any other applicable law.

 14. Governing Law. This Agreement shall be interpreted and enforced in accordance with the laws of the State of Delaware.

 15. Amendment and Termination. No amendment, modification, termination or cancellation of this Agreement shall be effective unless
in writing signed by both parties hereto. 
 16. Identical Counterparts. This Agreement may be executed in one or more counterparts,
each of which shall for all purposes be deemed to be an original but all of which together shall constitute but one and the same Agreement. Only one such counterpart need be produced to evidence the existence of this Agreement. 
 17. Headings. The headings of the sections of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction hereof. 
 18. Notices. All notices, requests, demands and other communications hereunder
shall be in writing and shall be deemed to have been duly given (i) upon delivery if delivered by hand to the party to whom such communication was 

 
directed or (ii) upon the third business day after the date on which such communication was mailed if mailed by certified or registered mail with
postage prepaid:

 NPS Pharmaceuticals, Inc.

  

 ULSBA Board of Directors
Guidelines 
 The Board of Directors plan that has been presented to the ULSBA has been created with the following guidelines: 
  

	1.	The Board of Directors plan (BDP) will be the same as the Active ULSBA Employee plan with Regence Blue Cross Blue Shield. 

  

	2.	Regence has given the BDP an exclusive group number. 

  

	3.	The BDP will not be given separate rates due to this exclusive group number. 

  

	4.	The BDP will be included in the underwriting procedures that are used to analyze the experience for the ULSBA. The BDP will not be underwritten as a single plan.

  

	5.	The employee who is transferred into the BDP from the current Active Employee plan, will receive new I.D. cards for both the medical and dental plans. The new I.D. cards will be the
only transition that the employee will endure. 

  

	6.	The BDP is exclusive to the ULSBA member companies that choose to adopt the plan for their own Board of Directors. If the ULSBA member company withdraws their membership from the
association, the BDP plan attached to that company will also be withdrawn. 

 The following guidelines must be met before an employee can be
added to the Board of Directors Plan: 
 “The following classes of individuals may be considered “eligible employees” for purposes of the
Contract if they otherwise meet the following requirements: sole proprietors, or partners of the employer if in an individual proprietor or partnership; corporate officers, managers, and employees of subsidiary or affiliated corporations if the
subsidiary or affiliated corporation is specifically named on the first page of this Contract; and a member of the Board of Directors may be eligible for coverage if the member; 1) is a United States citizen; 2) is not eligible for other group
coverage or Medicare; 3) was a full-time employee of the Group immediately prior to or concurrent with the board appointment; and 4) had coverage under the Group’s employer sponsored health insurance plan (to include COBRA coverage) without a
break in coverage for a minimum of one year immediately prior to or concurrent with the board appointment. Coverage as a board member will be paid by the Group under the standard employer contribution.”

 Exhibit F 
 to the 
 SEPARATION AGREEMENT 
 between 
 Hunter Jackson 
 and 
 NPS Pharmaceuticals, Inc.

  

 Restricted
Stock Award Agreement 
 dated January 5, 2004 

 NPS PHARMACEUTICALS, INC. 
 RESTRICTED STOCK AWARD AGREEMENT 
 1994 EQUITY INCENTIVE PLAN 

We are pleased to inform you that you have been awarded by NPS Pharmaceuticals, Inc., a Delaware corporation (the “Company”), a restricted
stock award (the “Restricted Stock Award”) under the Company’s 1994 Equity Incentive Plan, as amended to date (the “Plan”). 
 The terms of the Restricted Stock Award are as set forth in this Agreement and the Plan. Capitalized terms that are not defined in this Agreement have the meanings given to them in the Plan. The basic terms of the
Restricted Stock Award are summarized as follows: 
  

			
	Grantee:	  	Dr. Hunter Jackson
	Grant Date:	  	January 5, 2004
	Number of Shares:	  	4,000
	Fair Market Value Per Share on Grant Date:	  	$31.30
	Vesting Commencement Date:	  	January 5, 2004

  

	1.	Vesting 

 (a) The Restricted Stock Award is subject to
forfeiture upon termination of your employment or service relationship with the Company or a Related Corporation as described below. The Restricted Stock Award will vest and no longer be subject to forfeiture according to the following schedule:

  

			
	 Period of Your Continuous Employment or Service With the Company or a
Related Corporation
From the Vesting Commencement Date
	  	 Portion of Restricted Stock Award
 No Longer Subject to Forfeiture

	 After one year
	  	1,333 shares
	 After two years
	  	an additional 1,333 shares
	 After three years
	  	an additional 1,334 shares

 (b) Shares that have vested and are no longer subject to forfeiture according to the schedule above are referred
to herein as “Vested Shares.” Shares that have not vested and remain subject to forfeiture under the preceding schedule are referred to herein as “Unvested Shares.” The Unvested Shares will vest (and to the extent so vested cease
to be Unvested Shares remaining subject to forfeiture) in accordance with the above schedule. Collectively, the Unvested and Vested Shares are referred to herein as the “Shares.” 
 (c) Early lapse of the forfeiture restrictions may occur as described below. 

	2.	Termination of Employment or Services 

 If your employment or
service relationship with the Company or an Affiliate terminates for any reason, any portion of this Restricted Stock Award that has not vested will immediately terminate. You will be required to forfeit all Unvested Shares upon such occurrence
without the payment of any further consideration to you. 
  

	3.	Consideration for Restricted Stock Award 

 As required by
Delaware General Corporation Law, consideration not less than the par value of the Company’s common stock, which is $0.001 per share, has been paid by you to the Company for the Restricted Stock Award. 
  

	4.	Transfer Restrictions 

 Unvested Shares may not be sold,
transferred, assigned, pledged, encumbered or otherwise disposed of in contravention of the provisions of this Agreement. 
  

	5.	Acceleration 

 (a) Section 13.2 of the Plan shall apply
to this Restricted Stock Award. In summary, this means that in a transaction in which the vesting and exercisability of Stock Awards is accelerated pursuant to Section 13.2 of the Plan, the Shares will become vested and no longer subject to
forfeiture to the same extent that vesting and exercisability of Stock Awards is accelerated. If the Company splits or consolidates shares, pays any stock dividend or makes other similar capital adjustments, the Company will proportionately adjust
the number of Shares subject to this Agreement. 
 (b) Section 2.3 of the Agreement Providing Specialized Benefits Following Termination of Employment
Incident to a Merger, Acquisition or Other Change of Control or To Some Other Strategic Corporate Event shall apply to this Restricted Stock Award. In summary, this means that upon the occurrence of an event that would accelerate vesting of stock
options under the Severance Agreement, the occurrence of that event will also accelerate vesting of the Restricted Stock Award. 
  

	6.	Securities Law Compliance 

 Notwithstanding any other
provision of this Agreement, you may not sell the Shares unless they are registered under the Securities Act or, if such Shares are not then so registered, the Company has determined that such sale would be exempt from the registration requirements
of the Securities Act. The sale of the Shares must also comply with other applicable laws and regulations governing the Shares, and you may not sell the Shares if the Company determines that such sale would not be in material compliance with such
laws and regulations. 
  

	7.	Section 83(b) Election for Restricted Stock Award 

 You understand that under Section 83(a) of the Code, the excess of the Fair Market Value of the Unvested Shares on the date the forfeiture restrictions lapse over the purchase price, if any, paid for such Shares
will be taxed, on the date such forfeiture restrictions lapse, as ordinary income subject to payroll and withholding tax and tax reporting, as applicable. For this purpose, the term “forfeiture restrictions” means the right of the Company
to receive back any Unvested Shares upon termination of your employment or services with the Company or an Affiliate. You understand that you may elect under Section 83(b) of the Code to be taxed at the time the Unvested Shares are acquired,
rather than when and as the Unvested Shares cease to be subject to the forfeiture restrictions. Such election (an “83(b) Election”) must be filed with the Internal Revenue Service within 30 days from the Grant Date of the
Restricted Stock Award. 
 You understand that (a) you will not be entitled to a deduction for any ordinary income previously recognized
as a result of the 83(b) Election if the Unvested Shares are subsequently forfeited to the Company and (b) the 83(b) Election may cause you to recognize more ordinary income than you would have otherwise recognized if the value of the Unvested
Shares subsequently declines. 
 THE FORM FOR MAKING AN 83(b) ELECTION (AND FORM COVER LETTER TO BE SENT TO THE INTERNAL REVENUE SERVICE
ALONG WITH A COMPLETED SECTION 83(b) ELECTION) ARE ATTACHED TO THIS AGREEMENT AS EXHIBIT B. YOU UNDERSTAND THAT FAILURE TO FILE SUCH AN ELECTION WITHIN THE 30-DAY PERIOD MAY RESULT IN THE RECOGNITION OF 

 
ORDINARY INCOME BY YOU AS THE FORFEITURE RESTRICTIONS LAPSE. You further understand that an additional copy of such election form should be filed with your
federal income tax return for the calendar year in which the date of this Agreement falls. You acknowledge that the foregoing is only a summary of the federal income tax laws that apply to the purchase of the Unvested Shares under this Agreement and
does not purport to be complete. YOU FURTHER ACKNOWLEDGE THAT THE COMPANY HAS DIRECTED YOU TO SEEK INDEPENDENT ADVICE REGARDING THE APPLICABLE PROVISIONS OF THE CODE AND THE INCOME TAX LAWS OF ANY MUNICIPALITY OR STATE IN WHICH YOU MAY
RESIDE. 
 You agree to execute and deliver to the Company with this Agreement a copy of the Acknowledgment and Statement of Decision Regarding
Section 83(b) Election (the “Acknowledgment”) attached hereto as Exhibit A. You further agree that you will execute and deliver to the Company with this Agreement a copy of the 83(b) Election attached hereto as Exhibit B if
you choose to make such an election. 
  

	8.	Legends 

 You understand and agree that the
Shares are subject to forfeiture as set forth in this Agreement. You understand that the certificate(s) representing the Shares will bear legends in substantially the following form: 
 “The securities represented by this certificate are subject to certain restrictions on transfer and forfeiture and may not be sold, assigned,
transferred, encumbered or in any way disposed of except as set forth in a restricted stock award agreement between the issuer and the original recipient of these shares, a copy of which may be obtained at the principal office of the issuer. Such
transfer and forfeiture restrictions are binding on transferees of these shares.” 
  

	9.	Stop-Transfer Notices 

 You understand and
agree that, in order to ensure compliance with the restrictions referred to in this Agreement, the Company may issue appropriate “stop-transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own
securities, it may make appropriate notations to the same effect in its own records. The Company will not be required to (a) transfer on its books any Shares that have been sold or transferred in violation of the provisions of this Agreement or
(b) treat as the owner of the Shares, or otherwise accord voting, dividend or liquidation rights to, any transferee to whom the Shares have been transferred in contravention of this Agreement. 
  

	10.	Independent Tax Advice 

 You acknowledge that
determining the actual tax consequences to you of receiving or disposing of the Shares may be complicated. These tax consequences will depend, in part, on your specific situation and may also depend on the resolution of currently uncertain tax law
and other variables not within the control of the Company. You are aware that you should consult a competent and independent tax advisor for a full understanding of the specific tax consequences to you of receiving or disposing of the Shares. Prior
to executing this Agreement, you either have consulted with a competent tax advisor independent of the Company to obtain tax advice concerning the Shares in light of your specific situation or have had the opportunity to consult with such a tax
advisor but chose not to do so. 
  

	11.	Withholding and Disposition of Shares 

 You
agree to make arrangements satisfactory to the Company for the payment of any federal, state, local or foreign withholding tax obligations that arise either upon receipt of the Shares or as the forfeiture restrictions on any Shares lapse.
Notwithstanding the previous sentence, you acknowledge and agree that the Company and any Affiliate has the right to deduct from payments of any kind otherwise due to you any federal, state or local taxes of any kind required by law to be withheld
with respect this Restricted Stock Award. 

	12.	General Provisions 

 12.1 Assignment.
The Company may assign its rights under this Agreement at any time, whether or not such rights are then exercisable, to any person or entity selected by the Company’s Board of Directors, including, without limitation, one or more stockholders
of the Company. 
 12.2 Notices. Any notice required in connection with this Agreement will be given in writing and will be deemed
effective upon personal delivery or upon deposit in the U.S. mail, registered or certified, postage prepaid and addressed to the party entitled to such notice by 10 days’ advance written notice under this provision to all other
parties to this Agreement. 
 12.3 No Waiver. No waiver of any provision of this Agreement will be valid unless in writing and signed
by the person against whom such waiver is sought to be enforced, nor will failure to enforce any right hereunder constitute a continuing waiver of the same or a waiver of any other right hereunder. 
 12.4 Undertaking. You hereby agree to take whatever additional action and execute whatever additional documents the Company may deem necessary or
advisable in order to carry out or effect one or more of the obligations or restrictions imposed on either you or the Shares pursuant to the express provisions of this Agreement. 
 12.5 Agreement Is Entire Contract. This Agreement constitutes the entire contract between the parties hereto with regard to the subject matter
hereof. 
 12.6 Successors and Assigns. The provisions of this Agreement will inure to the benefit of, and be binding on, the Company
and its successors and assigns and you and your legal representatives, heirs, legatees, distributees, assigns and transferees by operation of law, whether or not any such person will have become a party to this Agreement and agreed in writing to
join herein and be bound by the terms and conditions hereof. 
 12.7 No Employment or Service Contract. This Agreement does not confer
upon you any right with respect to continuance of employment by the Company or any Affiliate, nor does it interfere in any way with the right of your employer to terminate your employment or services at any time. 
 12.8 Stockholder of Record. You will be recorded as a stockholder of the Company and will have, subject to the provisions of this Agreement, all
the rights of a stockholder with respect to the Shares. 
 12.9 Counterparts. This Agreement may be executed in two or more
counterparts, each of which will be deemed an original, but which, upon execution, will constitute one and the same instrument. 
 12.10
Governing Law. This Agreement will be construed and administered in accordance with and governed by the laws of the State of Utah. 
 IN
WITNESS WHEREOF, the parties have executed this Agreement on the day and year indicated above on the first page of this Agreement as the Grant Date.
