9.2 Value of Performance Units/Performance Shares. Each Performance Unit shall have an
initial value that is established by the Board at the time of grant. Each Performance Share shall have an initial value equal to the Fair Market Value of a Share on the date of grant. The Board shall set performance goals in its discretion which,
depending on the extent to which they are met, will determine the value and/or number of Performance Units/Performance Shares that will be paid out to the Participant.

9.3 Earning of Performance Units/Performance Shares. Subject to the terms of this Plan, after the applicable Performance Period has ended, the holder of Performance Units/Performance Shares shall be
entitled to receive payout on the value and number of Performance Units/Performance Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance goals have
been achieved.

9.4 Form and Timing of Payment of Performance Units/Performance Shares. Payment of earned Performance
Units/Performance Shares shall be as determined by the Board and as evidenced in the Award Agreement. Subject to the terms of this Plan, the Board, in its sole discretion, may pay earned Performance Units/Performance Shares in the
form of cash or in Shares (or in a combination thereof) equal to the value of the earned Performance Units/Performance Shares at the close of the applicable Performance Period, or as soon as practicable after the end of the Performance Period. Any
Shares may be granted subject to any restrictions deemed appropriate by the Board. The determination of the Board with respect to the form of payout of such Awards shall be set forth in the Award Agreement pertaining to the grant of the Award.

to retain Performance Units and/or Performance Shares following termination of the Participants employment with or provision of services to the Company, its Affiliates, and/or its Subsidiaries, as the case may be. Such provisions shall be
determined in the sole discretion of the Board, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Awards of Performance Units or Performance Shares issued pursuant to this Plan, and may

conditions, as the Board shall determine. Such Awards may involve the transfer of actual Shares to Participants, or payment in cash or otherwise of amounts based on the value of Shares and may include, without limitation, Awards designed to comply
with or take advantage of the applicable local laws of jurisdictions other than the United States.

10.3 Value of Cash-Based and Other
Stock-Based Awards. Each Cash-Based Award shall specify a payment amount or payment range as determined by the Board. Each Other Stock-Based Award shall be expressed in terms of Shares or units based on Shares, as determined by the Board.

depend on the extent to which the performance goals are met.

Awards. Payment, if any, with respect to a Cash-Based Award or an Other Stock-Based Award shall be made in accordance with the terms of the Award, in cash or Shares as the Board determines.

11



---

case may be. Such provisions shall be determined in the sole discretion of the Board, such provisions may be included in an agreement entered into with each
Participant, but need not be uniform among all Awards of Cash-Based Awards or Other Stock-Based Awards issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination.

Article 11. Transferability of Awards

11.1 Transferability.Except as provided in Section 11.2 below, during a Participants lifetime, his or her Awards shall be exercisable only by the Participant. Awards shall not be transferable other than by will or
the laws of descent and distribution; no Awards shall be subject, in whole or in part, to attachment, execution, or levy of any kind; and any purported transfer in violation hereof shall be null and void. The Board may establish such procedures as
it deems appropriate for a Participant to designate a beneficiary to whom any amounts payable or Shares deliverable in the event of, or following, the Participants death, may be provided.

11.2 Board Action. The Board may, in its discretion, determine that notwithstanding Section 11.1, any or all Awards (other than ISOs)
shall be transferable to and exercisable by such transferees, and subject to such terms and conditions, as the Board may deem appropriate; provided, however, no Award may be transferred for value (as defined in the General Instructions to Form S-8
under the Securities Act of 1933, as amended).

11.3 Domestic Relations Orders.Without limiting the generality of
Section 11.1, and notwithstanding Section 11.2, no domestic relations order purporting to authorize a transfer of an Award shall be recognized as valid.

Article 12. Performance Measures

Measures as compared to the performance of a group of comparator companies, or published or special index that the Board, in its sole discretion, deems appropriate, or the Company may select Performance Measure (j) above as compared to various
stock market indices. The Board also has the authority to provide for accelerated vesting of any Award based on the achievement of performance goals pursuant to the Performance Measures specified in this Article 12.

12.2 Evaluation of Performance. The Board may provide in any such Award that any evaluation
of performance may include or exclude any of the following events that occurs during a Performance Period: (a) asset write-downs, (b) litigation or claim judgments or settlements, (c) the effect of changes in tax laws, accounting
principles, or other laws or provisions affecting reported results, (d) any reorganization and restructuring programs, (e) extraordinary nonrecurring items as described in Accounting Principles Board Opinion No. 30 and/or in
managements discussion and analysis of financial condition and results of operations appearing in the Companys annual report to shareholders for the applicable year, (f) acquisitions or divestitures, and (g) foreign exchange
gains and losses. To the extent such inclusions or exclusions affect Awards to Covered Employees, they shall be prescribed in a form that meets the requirements of Code Section 162(m) for deductibility.

12.3 Adjustment of Performance-Based Compensation. Awards that are intended to qualify as Performance-Based Compensation may not be adjusted
upward. The Board shall retain the discretion to adjust such Awards downward, either on a formula or discretionary basis or any combination, as the Board determines.

12.4 Board Discretion. In the event that applicable tax and/or securities laws change to permit Board discretion to alter the governing Performance Measures without obtaining shareholder approval of such
changes, the Board shall have sole discretion to make such changes without obtaining shareholder approval. In addition, in the event that the Board determines that it is advisable to grant Awards that shall not qualify as Performance-Based
Compensation, the Board may make such grants without satisfying the requirements of Code Section 162(m) and base vesting on Performance Measures other than those set forth in Section 12.1.

Article 13. Dividend Equivalents

Any
Participant selected by the Board may be granted dividend equivalents based on the dividends declared on Shares that are subject to any Award, to be credited as of dividend payment dates, during the period between the date the Award is granted and
the date the Award is exercised, vests or expires, as determined by the Board. Such dividend equivalents shall be converted to cash or additional Shares by such formula and at such time and subject to such limitations as may be determined by the
Board.

Article 14. Beneficiary Designation

Each Participant under this Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under this Plan is to be paid in case of his death
before he receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a form prescribed by the Board, and will be effective only when filed by the Participant in writing
with the Company during the Participants lifetime. In the absence of any such beneficiary designation, benefits remaining unpaid or rights remaining unexercised at the Participants death shall be paid or exercised by the
Participants executor, administrator, or legal representative.

Article 15. Rights of Participants

15.1 Employment. Nothing in this Plan or an Award Agreement shall interfere with or limit in any way the right of the Company, its
Affiliates, and/or its Subsidiaries, to terminate any Participants employment or service on the Board or to the Company at any time or for any reason not prohibited by law, nor confer upon any Participant any right to continue his employment
or service as a Director or Third Party Service Provider for any specified period of time.

Neither an Award nor any benefits arising under
this Plan shall constitute an employment contract with the Company, its Affiliates, and/or its Subsidiaries and, accordingly, subject to Articles 3 and 16, this Plan and the benefits hereunder may be terminated at any time in the sole and
exclusive discretion of the Board without giving rise to any liability on the part of the Company, its Affiliates, and/or its Subsidiaries.



13

15.2 Participation. No individual shall have the right to be selected to receive an
Award under this Plan, or, having been so selected, to be selected to receive a future Award.

15.3 Rights as a
Stockholder. Except as otherwise provided herein, a Participant shall have none of the rights of a stockholder with respect to Shares covered by any Award until the Participant becomes the record holder of such Shares.

Article 16. Amendment, Modification, Suspension, and Termination

16.1 Amendment, Modification, Suspension, and Termination. Subject to Section 16.3, the Board may, at any time and from time to time, alter, amend, modify, suspend, or terminate this Plan
and any Award Agreement in whole or in part; provided, however, that, without the prior approval of the Companys stockholders and except as provided in Section 4.4, Options or SARs issued under this Plan will not be repriced,
replaced, or regranted through cancellation, or by lowering the Option Price of a previously granted Option or the Grant Price of a previously granted SAR, and no material amendment of this Plan shall be made without stockholder approval if
shareholder approval is required by law, regulation, or stock exchange rule.

16.2 Adjustment of Awards Upon the Occurrence of Certain
Unusual or Nonrecurring Events.The Board may make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in
Section 4.4 hereof) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations, or accounting principles, whenever the Board determines that such adjustments are appropriate in order to
prevent unintended dilution or enlargement of the benefits or potential benefits intended to be made available under this Plan. The determination of the Board as to the foregoing adjustments, if any, shall be conclusive and binding on Participants
under this Plan.

16.3 Awards Previously Granted. Notwithstanding any other provision of this Plan to the contrary (other than
Section 16.4), no termination, amendment, suspension, or modification of this Plan or an Award Agreement shall adversely affect in any material way any Award previously granted under this Plan, without the written consent of the
Participant holding such Award.

16.4 Amendment to Conform to Law. Notwithstanding any other provision of this Plan to the
contrary, the Board of Directors may amend the Plan or an Award Agreement, to take effect retroactively or otherwise, as deemed necessary or advisable for the purpose of conforming the Plan or an Award Agreement to any present or future law relating
to plans of this or similar nature (including, but not limited to, Code Section 409A), and to the administrative regulations and rulings promulgated thereunder.

Article 17. Withholding

The Company shall have the power and the right to deduct or withhold, or
require a Participant to remit to the Company, the minimum statutory amount to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this
Plan.

Article 18. Corporate Transactions

In the event of (a) a merger or consolidation in which the Company is not the surviving corporation; (b) a reverse merger in which the Company is the surviving corporation but the shares of the
Companys common stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash, or otherwise; (c) a strategic corporate event, such as a merger or
acquisition, where the Company is technically the surviving entity, but where other elements of a change of control are present, i.e., change in management team or Board composition; (d) a transaction which the Board determines in its sole
discretion to constitute a change in control of the Company; or (e) any capital reorganization in which fifty percent (50%) of the Shares of the Company entitled to vote are exchanged, then, the time during which Awards outstanding under
the Plan become vested shall be accelerated and all outstanding Awards shall become immediately exercisable upon such event and such Awards shall continue to be exercisable until the later of (i) twenty-four (24) months from the



14



---

effective date of such event, or (ii) the time specified in the Award Agreement during which the Award is exercisable following a Participants
termination of service; provided, however, that in no event shall the Award be exercisable after the expiration of its term.

Article
19. Successors

All obligations of the Company under this Plan with respect to Awards granted hereunder shall be binding on any
successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

Article 20. General Provisions

Forfeiture Events.



| | (a) | The Board may specify in an Award Agreement that the Participants rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation,

cause, termination of the Participants provision of services to the Company, Affiliate, and/or Subsidiary, violation of material Company, Affiliate, and/or Subsidiary policies, breach of noncompetition, confidentiality, or other restrictive

| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement
under the securities laws, if the Participant knowingly or grossly negligently engaged in the misconduct, or knowingly or grossly negligently failed to prevent the misconduct, or if the Participant is one of the individuals subject to automatic
forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, the Participant shall reimburse the Company the amount of any payment in settlement of an Award earned or accrued during the twelve (12) month period following the first
public issuance or filing with the United States Securities and Exchange Commission (whichever just occurred) of the financial document embodying such financial reporting requirement.

include the feminine, the plural shall include the singular, and the singular shall include the plural.

20.4
Severability.In the event any provision of this Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Plan, and this Plan shall be construed and enforced as
if the illegal or invalid provision had not been included.

20.5 Requirements of Law.The granting of Awards and the
issuance of Shares under this Plan shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required.

20.6 Delivery of Title.The Company shall have no obligation to issue or deliver evidence of title for Shares issued under this
Plan prior to:



| | (a) | obtaining any approvals from governmental agencies that the Company determines are necessary or advisable; and

15



---

| | (b) | completion of any registration or other qualification of the Shares under any applicable national or foreign law or ruling of any governmental body that the Company determines to be
necessary or advisable.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

20.7 Inability to Obtain Authority.The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is deemed by the Companys counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the
failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

20.8 Investment
Representations.The Board may require any individual receiving Shares pursuant to an Award under this Plan to represent and warrant in writing that the individual is acquiring the Shares for investment and without any present
intention to sell or distribute such Shares.

20.9 Employees Based Outside of the United States.Notwithstanding any provision
of this Plan to the contrary, in order to comply with the laws in other countries in which the Company, its Affiliates, and/or its Subsidiaries operate or have Employees, Directors, or Third Party Service Providers, the Board, in its sole
discretion, shall have the power and authority to:



| | (a) | determine which Affiliates and Subsidiaries shall be covered by this Plan;
| | --- | --------------------------------------------------------------------------



| | (b) | determine which Employees and/or Directors or Third Party Service Providers outside the United States are eligible to participate in this Plan;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | modify the terms and conditions of any Award granted to Employees, Directors or Third Party Service Providers outside the United States to comply with applicable foreign laws;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | establish subplans and modify exercise procedures and other terms and procedures, to the extent such actions may be necessary or advisable. Any subplans and modifications to Plan
terms and procedures established under this Section 20.9 by the Board shall be attached to this Plan document as appendices; and
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | take any action, before or after an Award is made, that it deems advisable to obtain approval or comply with any necessary local government regulatory exemptions or approvals.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Notwithstanding the above, the Board may not take any actions hereunder, and no Awards shall be granted, that would violate
applicable law.

transfer of Shares, the transfer of such Shares may be effected on a noncertificated basis, to the extent not prohibited by applicable law or the rules of any stock exchange.

its Subsidiaries, and/or its Affiliates may make to aid it in meeting its obligations under this Plan. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a
fiduciary relationship between the Company and any Participant, beneficiary, legal representative, or any other individual. To the extent that any person acquires a right to receive payments from the Company, its Subsidiaries, and/or its Affiliates
under this Plan, such right shall be no greater than the right of an unsecured general creditor of the Company, a Subsidiary, or an Affiliate, as the case may be. All payments to be made hereunder shall be paid from the general funds of the Company,
a Subsidiary, or an Affiliate, as the case may be and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in this Plan.

---

20.12 No Fractional Shares. No fractional Shares shall be issued or delivered pursuant
to this Plan or any Award. The Board shall determine whether cash, Awards, or other property shall be issued or paid in lieu of fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated.

20.13 Retirement and Welfare Plans. Neither Awards made under this Plan nor Shares or cash paid pursuant to such
Awards, except pursuant to Covered Employee Annual Incentive Awards, may be included as compensation for purposes of computing the benefits payable to any Participant under the Companys or any Subsidiarys or Affiliates
retirement plans (both qualified and non-qualified) or welfare benefit plans unless such other plan expressly provides that such compensation shall be taken into account in computing a Participants benefit.

20.14 Deferred Compensation.No deferral of compensation (as defined under Code Section 409A or guidance thereto) is intended under this
Plan. Notwithstanding this intent, if any Award would be considered deferred compensation as defined under Code Section 409A and if the Plan fails to meet the requirements of Code Section 409A with respect to such Award, then such Award
shall be null and void. However, the Board may permit deferrals of compensation pursuant to the terms of a Participants Award Agreement, a separate plan or a subplan which meets the requirements of Code Section 409A and any related
guidance. Additionally, to the extent any Award is subject to Code Section 409A, notwithstanding any provision herein to the contrary, the Plan does not permit the acceleration of the time or schedule of any distribution related to such Award,
except as permitted by Code Section 409A, the regulations thereunder, and/or the Secretary of the United States Treasury.

20.15
Nonexclusivity of this Plan. The adoption of this Plan shall not be construed as creating any limitations on the power of the Board or Board to adopt such other compensation arrangements as it may deem desirable for any Participant.

20.16 No Constraint on Corporate Action. Nothing in this Plan shall be construed to: (a) limit, impair, or otherwise
affect the Companys or a Subsidiarys or an Affiliates right or power to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure, or to merge or consolidate, or dissolve, liquidate,
sell, or transfer all or any part of its business or assets; or (b) limit the right or power of the Company or a Subsidiary or an Affiliate to take any action which such entity deems to be necessary or appropriate.

20.17 Governing Law. The Plan and each Award Agreement shall be governed by the laws of the State of Delaware, excluding any conflicts or
choice of law rule or principle that might otherwise refer construction or interpretation of this Plan to the substantive law of another jurisdiction. Unless otherwise provided in the Award Agreement, recipients of an Award under this Plan are
deemed to submit to the exclusive jurisdiction and venue of the federal or state courts of Delaware, to resolve any and all issues that may arise out of or relate to this Plan or any related Award Agreement.

TERMS AND CONDITIONS



|1. | Grant of Option. The Company hereby irrevocably grants to the Optionee the right and option (the Option) to purchase the above number of Optioned Shares of the
Companys Common Stock in the manner and subject to the conditions provided herein and in the Plan.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Purchase Price and Payment.
|-- | ---------------------------



| | 2.1 | The purchase price (the Exercise Price) shall be the amount per share of the Optioned Shares shown above, which is the fair market value of the Common Stock on the Date
of Grant as determined under the Plan. To the extent that the Optionee being granted this Option owns stock possessing more than ten percent of the total combined voting power of all classes of stock of the Company or its subsidiary corporations,
then the Exercise Price has been established by the Company to be equal to at least one hundred ten percent of said fair market value.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.2. | Payment of the Exercise Price per Optioned Share shall be paid, to the extent permitted by applicable statutes and regulations, either (a) in cash, or (b) by delivery of
already-owned shares of Common Stock (which has been held by Optionee for at least six months), or a combination of cash and already-owned Common Stock, or (c) according to a deferred payment or other arrangement as agreed to between the
Optionee and the Company, or (d) pursuant to a broker assisted exercise same-day sales program, or (e) a combination of (a), (b), (c), and/or (d) above. With regard to delivery of shares of Common Stock under (b) above, such
shares of Common Stock (i) shall be valued for determination of the payment of the Exercise Price of such delivered shares of Common Stock at the shares fair market value on the Date of Exercise, and (ii) must be owned free and clear
of any liens, claims, encumbrances, or security interests on such date.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.3 | In the case of any deferred payment arrangement, interest shall be payable at least annually, and shall be charged at the minimum rate of interest necessary to avoid the treatment
as interest under any applicable provisions of the Code of any amounts other than amounts stated to be interest under the deferred payment arrangement.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2.4 | Notwithstanding the foregoing, this Option may be exercised pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board, which results in the
receipt of cash (or check) by the Company prior to the issuance of any of the Optioned Shares.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Vesting and Term of Option. The Optioned Shares shall be exercisable during the term of this Option Agreement but only on the terms hereof and pursuant to the following
exercise schedule:
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Twenty-eight percent of the Optioned Shares shall vest at 5:00 p.m., Mountain Standard Time
(MST), on the first anniversary of the Date of Grant and two percent of the remaining Optioned Shares shall vest at 5:00 p.m. MST, on each monthly anniversary date thereafter, provided that the Optionee was, during the entire period
prior to such vesting date, continuously employed as an employee of the Company or otherwise affiliated in a position qualifying for continued vesting under the Plan. With respect to Canadian employees, Optionees status as an employee shall
terminate upon delivery of a notice of termination by the Company.

Except as provided in the Employment Agreement between Participant and
the Company dated October , 2005 (Employment Agreement), vesting will cease upon the termination of your continuous status as an employee, director or consultant (Continuous Service). Vesting of
the Stoack Appreciation Right granted hereunder may be accelerated on the occurrence of certain events set forth in the Employment Agreement.

The term of the Option is from the Date of Grant through the Expiration Date shown above. Except to the extent that a different Expiration Date is shown above, any portion of the Optioned Shares, which become exercisable shall remain in
effect and be exercisable thereafter during the term of the Option. The Option shall not be exercisable after the Expiration Date. Not less than one hundred shares of the Optioned Shares may be purchased at any time unless the number purchased is
the total number at the time purchasable under the Option. Notwithstanding the above, as to any Option granted to a person owning more than ten percent of the Companys voting stock on the Date of Grant, such Option shall expire five years from
the Date of Grant and said date shall be the Expiration Date.



---

|4. | Termination of Employment or Relationship as a Director or Consultant. In the event an Optionees continual status as an employee, director, or consultant (other
than upon the Optionees death or disability) shall terminate prior to the Expiration Date, then this Option shall expire ninety days after the termination of the later of employment with the Company or such affiliation with the Company for any
reason, or for no reason, unless:
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.1 | such termination of employment or affiliation is due to Optionees permanent or total disability (within the meaning of Section 422(c)(6) of the Code), in which event the
Option shall expire on the earlier of the Expiration Date set forth above, or twelve months following such termination of employment or affiliation;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.2 | such termination of employment or affiliation is due to Optionees death, in which event the Option shall expire on the earlier of the Expiration Date set forth above or
eighteen months after Optionees death;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.3 | exercise of the Option within ninety days after termination of employment or affiliation with the Company would result in liability of the Optionee under Section 16(b) of the
Securities Exchange Act of 1934 (arising, for example, from a non-exempt purchase), in which case the Option will expire on the earlier of (a) the Expiration Date set forth above, (b) the tenth day after the last day upon which exercise
would result in such liability, or (c) six months and ten days after the termination of Optionees employment or affiliation; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.4 | such termination of employment or affiliation is due to a termination without Cause by the Company or a resignation for Good Reason by Optionee, in which event the Option shall
expire on the earlier of the Expiration Date set forth above, or twenty-four months following such termination of employment or affiliation.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This Option may be exercised following termination of employment or affiliation only as to that number of Optioned Shares as to which it was exercisable on the date of termination of employment or affiliation under
the provisions of this Option Agreement.



|5. | Transferability.
|-- | ----------------



| | 5.1 | Incentive Stock Option (ISO). In the case of an ISO, this Option is not transferable, except by will or by the laws of descent and distribution, and is
exercisable during Optionees life, only by the Optionee. In the event an Optionee transfers such Option, such transfer shall constitute a disqualifying event and the Option shall no longer qualify as an ISO but shall be considered a
Non-Qualified Stock Option under the terms of this Plan.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5.2 | Non-Qualified Stock Option (NQSO). In the case of a NQSO, this Option is not transferable, except as follows:
| | --- | ---------------------------------------------------------------------------------------------------------------



| | 5.2.1 | By will or by the laws of descent and distribution or pursuant to a qualified domestic relations order as defined by the Code or Title I of the Employee Retirement Income Security
Act, or the rules thereunder (a QDRO), and shall be exercisable during the lifetime Optionee only by such Optionee or any transferee pursuant to a QDRO; and
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5.2.2 | Transfers to the spouse, children, or grandchildren of the Optionee (Immediate Family Members), a trust or trusts for the exclusive benefit of such Immediate Family
Members, or a partnership in which such Immediate Family Members are the only partners, provided that (a) there may be no consideration for any such transfer, (b) subsequent transfers of transferred options shall be prohibited except those
occurring by will or the laws of descent and distribution, and (c) the Option shall continue to be subject to all the terms and conditions that applied prior to transfer. The Options shall be exercisable by the transferee only to the extent and
for the periods specified in this Option Agreement or the Plan. The Company expressly disclaims any obligation to provide notice to a transferee of the expiration of the Option.
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | 5.3 | Non-Qualifying Transfer. In the event of the transfer of the Optioned Shares obtained by exercise of an ISO in such manner as to disqualify the Optioned Shares for ISO
treatment, the provisions of this Grant and the Plan applicable to NQSOs shall be deemed to apply to the Optioned Shares as if the Grant had been an NQSO.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | No Employment Relationship. This Option is not an employment contract and nothing in this Option Agreement shall be deemed to create in any way whatsoever any obligation on
Optionees part to continue in the employ of the Company or as an affiliate of the Company, or of the Company to continue Optionees employment or affiliation with the Company. In the event that this Option is granted in connection with
the performance of services as a consultant or director, references to employment, employee, and similar terms shall be deemed to include the performance of services as a consultant or a director, as the case may be, provided however, that no rights
as an employee shall arise by reason of the use of such terms.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | Rights of Stockholder. No rights as a stockholder are created or conferred hereby until the date of issue of a stock certificate for the shares of the Optioned Shares covered
by a valid exercise of this Option.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | Restriction on Transfer. A purchaser of shares of Common Stock who purchases such Optioned Shares by exercise of this Option may not dispose of such Optioned Shares within
two years from the Date of Grant or within one year after the date of exercise without losing the purchasers right to treat such Optioned Shares as an ISO. Other contractual or legal restrictions may also apply to ISOs.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | Method of Exercising Option.
|-- | ----------------------------



| | 9.1 | Subject to the terms and conditions of this Option Agreement, the Option may be exercised by written notice (in a form designated by the Company) to the Company at its principal
office. Such notice shall state the election to exercise the Option and the number of Optioned Shares in respect of which it is being exercised, and shall be signed by the person or persons so exercising the Option. If the option being exercised was
granted partially as ISOs as to certain shares and as NQSOs as to the balance of the shares, the Company will assume that the shares being exercised are pro-rata ISO and NQSO unless specifically otherwise directed or elected by the Optionee. Such
notice shall either:
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.1.1 | be accompanied by payment of the full Exercise Price of such Optioned Shares, in which event the Company shall deliver a certificate promptly after the notice shall be received; or
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 9.1.2 | fix a date (not less than five nor more than ten business days from the date such notice is received by the Company unless a longer date or different arrangement has been
established under paragraph 2 hereof) for the payment of the full Exercise Price of such Optioned Shares, against delivery of a certificate or certificates representing such Optioned Shares.

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.

| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|-- | -------------------

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.
|-- | ------------------------

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.
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



2



---

| | 8.1.2 | Employee agrees that during the period of employment with the Company, and for a period of twenty four (24) months thereafter, Employee shall not directly or indirectly
(a) compete with the business of the company by calling on, soliciting, taking away, or attempting 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.

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.
|--- | ------------------

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

| | ---- | -------------------------------------------------------------------------------------------------------------------------------



| | 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:

RECITALS

WHEREAS, Agent performs a valuable service to the Corporation in the capacity as an
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 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 after the date hereof, the parties hereto agree as follows:



|1. | Services to the Corporation. With duties beginning as of the above date, Agent will serve, at the will of the Corporation or under separate contract, if any such contract
exists, as an officer 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 Agents ability so long as Agent 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:
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.1 | against any and all expenses (including attorneys fees), witness fees, damages, judgments, fines, 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 Agent 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
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.2 | 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.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



1



---

|4. | Limitations on Additional Indemnity. No indemnity shall be paid by the Corporation under this agreement:
|-- | --------------------------------------------------------------------------------------------------------



| | 4.1 | 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;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.2 | on account of Agents conduct that was knowingly fraudulent or deliberately dishonest or that constituted willful misconduct;
| | --- | -----------------------------------------------------------------------------------------------------------------------------



| | 4.3 | 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;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.4 | 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;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.5 | 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
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4.6 | 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:
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7.1 | the Corporation will be entitled to participate therein at its own expense;
| | --- | ---------------------------------------------------------------------------



2



---

| | 7.2 | 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
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7.3 | 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 that 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 Agent has
acted in bad faith or in a manner that Agent did not believe to be in or not opposed to the best interests of the Corporation, that Agent is not entitled to indemnification due to exclusion under Section 4 hereof or, with respect to any
criminal action or proceeding that Agent acted without reasonable cause to believe that Agents 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.
|-- | ------------



| | 9.1 | 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 Agents 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

NPS PHARMACEUTICALS, INC.

CHANGE IN CONTROL SEVERANCE PAY PLAN

ADOPTED BY THE BOARD OF DIRECTORS

FEBRUARY 10, 2005

1. Introduction.The purpose of the NPS Pharmaceuticals, Inc. Change in Control Severance Pay Plan (the Plan) is to provide severance benefits to eligible employees of NPS Pharmaceuticals, Inc. and its subsidiaries
(collectively Company) when there has been a change in control of the Company resulting in the eligible employees job prospects being materially altered. This Plan replaces any prior severance policy or
other policy or practice under which severance benefits have been provided to employees of the Company, except as provided in Section 13 herein. This document constitutes both the written instrument under which the Plan is maintained and the
summary plan description for the Plan.

2. Effective Date.The effective date of the Plan is January 1, 2005.

3. Term.The Plan shall be in effect until terminated by the Company.

4. ERISA. For Covered Employees in the United States, the Plan is intended to be, and shall be, administered and maintained as, a welfare benefit
plan under the Employee Retirement Income Security Act of 1974, as amended.

5. Employment Standards Act. For Covered
Employees in Canada, the Plan is intended to provide the severance benefits required under the Canadian Employment Standards Act, as amended from time to time (Employment Standards Act). To the extent that any provisions of the Plan
conflict with the Employment Standards Act, the Employment Standards Act shall govern Covered Employees in Canada.

6. Important Terms.The following words and phases shall have the following respective meanings unless the context clearly indicates otherwise:

6.1
Administrator means the Company, acting through its Vice President, Human Resources, or such other person appointed by the Board.

6.2 Base Pay means the Covered Employees annual regular straight-time salary as in effect on the date of termination of employment.

6.3 Board means the Board of Directors of the Company.

6.4 Cause means (i) an act of material dishonesty by the Covered Employee in connection with the Covered Employees responsibilities as an employee, (ii) the Covered Employees
conviction of, or plea of nolo contendere to, a felony, (iii) the Covered Employees gross misconduct in connection with the Covered Employees responsibilities as an employee, (iv) the Covered Employees violation of the
Companys written policies and procedures; or (v) the Covered Employees continued failure to perform his or her responsibilities as an employee after the Covered Employee has received a written demand for such performance.

6.5 Change in Control means (i) a dissolution or liquidation or sale of all or substantially all of the assets of
the Company; (ii) a merger or consolidation in which the Company is not the surviving corporation; (iii) a reverse merger in which the Company is the surviving corporation but the shares of the Companys common stock outstanding
immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash, or otherwise; (iv) a strategic corporate event, such as a merger or acquisition, where the Company is
technically the surviving entity, but which the Board determines in its sole discretion that other elements of a Change in Control are present, i.e., a substantial change in the management team or composition of the Board; (v) a transaction
which the Board determines in its sole discretion to constitute a Change in Control of the Company: or (vi) any other capital reorganization in which more than 50% of the shares of the Company entitled to vote are exchanged. A Change in Control
does not include the occurrence of an event described in (i), (ii), (iii) or (iv) where the sole parties to the event are NPS Pharmaceuticals, Inc. and one of its subsidiaries.

time within the Determination Period for a Covered Employee following a Change in Control (i) the Covered Employees job prospects are Materially Altered, or (ii) the Covered Employees employment is Involuntarily Terminated,

Upon timely exercise of his or her rights under the Plan, the Covered Employee will receive the following
Severance Benefit from the Company:

8.1.1 Total Cash Compensation Target.Within 30 days of the execution of the Release as

severance pay is governed by the Employment Standards Act will be the greater of that determined under Section 8.1.1 or the amount required under the Employment Standards Act.

8.1.3 Continued Medical Benefits.If Covered Employee, and any spouse and/or dependents of Covered Employee (Family Members), has
medical and dental coverage on the date of Covered Employees termination of employment under a group health plan sponsored by the Company, the Company will reimburse Covered Employee 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 11611168; 26 U.S.C. Section 4980B(f), as amended, and all applicable regulations (referred to collectively as COBRA) for Covered Employee
and his Family Members during the full term of the Severance Period (to the extent COBRA coverage lasts for the full term); provided, that the Company shall have no obligation to reimburse Covered Employee for the premium cost of COBRA coverage
beginning on or after the date Covered Employee and his Family Members first become eligible to obtain comparable benefits from a subsequent employer.

8.1.4 Stock Option Accelerated Vesting and Extended Exercise Period. Provisions for 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 Plans and Options also provide for an extended time for exercise of such Options upon an Involuntary Termination initiated by the
Covered Employee or a termination initiated by the Company in either case upon a Change in Control for Company employees generally and for Covered Employees in particular. The terms of such stock option plans and grants made thereunder remain in
full force and effect.

8.1.5 Short Term Incentive Earned Prior to Date of Termination. In the event that the Covered
Employees date of termination is prior to the date that the amount of short term incentive earned by employees of the Company for that year is determined, if any, the Covered Employee will be entitled to receive, in addition to the Total Cash
Compensation Target, a pro rata share of his or her actual short term incentive earned for such year, if any, e.g., if the Covered Employees date of termination is July 1, he or she will be entitled to receive 50% of his or her actual
short term incentive. Such pro rata short term incentive payment will be paid according to the terms of the Companys compensation program in effect for the calendar year in which the Involuntary Termination of the Covered Employee occurs. The
Covered Employees pro rata share of actual short term incentive for such year will be paid to the Covered Employee at the same time that it is paid to employees of the Company generally, regardless of the Covered Employees date of
termination of employment.

8.2 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 the termination of the Covered Employees employment with the Company and its subsidiaries and affiliates, in the form set forth on Exhibit B.

8.3 Vacation and PTO Days.Any unused vacation or personal time off (PTO) 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 Total Cash Compensation Target payment. No Covered Employee may use any accrued but unused vacation or PTO pay to extend his or her Involuntary Termination
date or to postpone or delay the start of his or her Severance Period.

9. 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.

---

10. 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, the authority to take such
actions is subject to the prior approval of the Board.

11. 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 chief executive officer of the Company will act upon
any matters pertaining specifically to the benefit or eligibility of the Administrator under the Plan.

12. Amendment or Termination.The Company reserves the right to amend or modify the Plan at any time, without advance notice to any Covered Employee, including but not limited to the Severance Periods set forth on Exhibit A.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 Periods or Severance Periods 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.

13. Severance Agreements for Certain Covered Employees. Certain Covered Employees have previously entered into
written severance agreements with the Company prior to December 1, 2004. Such Covered Employees will not be entitled to severance benefits under both the Plan and their written agreements. Within five (5) days of the Covered
Employees Involuntary Terminaion, the Covered Employee shall elect whether he or she will receive benefits under the written severance agreement or the Plan.

14. 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 or his or her designee. 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.

15. 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.

16. 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.

17. 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.

18. 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, including Covered Employees, at any time, with or without cause.

19. Applicable Law and Choice of Forum.The provisions
of the Plan will be construed, administered and enforced in accordance with ERISA and, to the extent applicable, the laws of Canada or the State of Utah. The Covered Employee agrees that any action brought under the Plan will be brought in the State
of Utah.

20. 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.

21.
Headings.Headings in this Plan document are for purposes of reference only and will not limit or otherwise affect the meaning hereof.

22. 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 by
written agreement, by-laws, incorporation documents or state law.

23. Breach and Attorneys Fees.In the event that a Covered
Employee breaches the waiver and release attached as Exhibit B, to the fullest extent permitted by law (including the Employment Standards Act), the Company shall be entitled to pursue all legal remedies against the Covered Employee and the Covered
Employee shall be liable to the Company for its reasonable attorneys fees and costs incurred in pursuing such legal remedies.

24. Representations by the Company.Except as provided in Section 12 above, no employee, officer, director, or agent of the Company has the authority to alter, vary, modify, or waive the terms and conditions of the Plan. Except
as provided in Section 13 above, no verbal or written representations that are in addition to or contrary to the terms of the Plan and its written amendments shall be binding on the Plan, the Administrator or the Company.

25. Return of Company Property. All property of the Company, including but not limited to keys, credit cards, documents, records, office
equipment, computers, cell phones, etc., must be returned by the Covered Employee to the Company within five (5) business days of the Covered Employees Involuntary Termination in order for the Covered Employee to receive the Severance
Benefit.

26. Additional Information.

27. Statement of ERISA Rights for U.S. Employees.Under ERISA, Covered Employees have
certain rights and protections:

27.1 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.

27.2 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.

27.3 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.)

27.4 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.

27.5 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.

27.6 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 directory, 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.

such legal remedies.
