B. EXERCISE OF TANDEM SARS. Tandem SARs may be exercised for all or part of the Shares subject to the related Option upon the surrender of the right to exercise the equivalent portion of the related Option. A Tandem SAR may be exercised only with respect to the Shares for which its related Option is then exercisable.

Notwithstanding any other provision of this Plan to the contrary, with respect to a Tandem SAR granted to an Employee in connection with an ISO: (i) the Tandem SAR will expire no later than the expiration of the underlying ISO; (ii) the value of the payout with respect to the Tandem SAR may be for no more than one hundred percent (100%) of the difference between the Option Price of the underlying ISO and the Fair Market Value of the Shares subject to the underlying ISO at the time the Tandem SAR is exercised; and (iii) the Tandem SAR may be exercised only when the Fair Market Value of the Shares subject to the ISO exceeds the Option Price of the ISO.

At the discretion of the Committee, the payment upon SAR exercise may be in cash, in Shares of equivalent value, or in some combination thereof. The Committee’s determination regarding the form of SAR payout shall be set forth in the Award Agreement pertaining to the grant of the SAR.

G. TERMINATION OF EMPLOYMENT BY A PARTICIPANT WHO IS AN EMPLOYEE.

All rights with respect to the Restricted Stock granted to a Participant under the Plan shall be available during his or her lifetime only to such Participant or the Participant’s legal representative for the Period of Restriction.

D. OTHER RESTRICTIONS. Subject to Article XI herein, the Committee may impose such other conditions and/or restrictions on any Shares of Restricted Stock granted pursuant to the Plan as it may deem advisable including, without limitation, a requirement that Participants pay a stipulated purchase price for each Share of Restricted Stock, restrictions based upon the achievement of specific performance goals (Company-wide, divisional and/or individual), time-based restrictions on vesting following the attainment of the performance goals and/or restrictions under applicable federal or state securities laws.

The Company may retain the certificates representing Shares of Restricted Stock in the Company’s possession until such time as all conditions and/or restrictions applicable to such Shares have been satisfied.

F. DIVIDENDS AND OTHER DISTRIBUTIONS. During the Period of Restriction, Participants holding Shares of Restricted Stock granted hereunder shall be credited with regular cash dividends paid with respect to the underlying Shares while they are so held. The Committee may apply any restrictions to the dividends that the Committee deems appropriate. Without limiting the generality of the preceding sentence, if the grant or vesting of Restricted Stock granted to a Covered Employee is designed to comply with the requirements of the Performance-Based Exception, the Committee may apply any restrictions it deems appropriate to the payment of dividends declared with respect to such Restricted Stock, such that the dividends and/or the Restricted Stock maintain eligibility for the Performance-Based Exception. Notwithstanding anything to the contrary herein, (i) dividends accrued on Restricted Stock will only be paid if the Restricted Stock vests; and (ii) for any Award that is governed by Code Section 409A regarding non-qualified deferred compensation, the Committee shall establish the schedule of any payments of dividends in accordance with the requirements of Code Section 409A or any guidance promulgated thereunder.

G. TERMINATION OF EMPLOYMENT BY A PARTICIPANT WHO IS AN EMPLOYEE. With respect to a Participant who is an Employee, each Restricted Stock Award Agreement shall set forth the extent to which the Participant shall have the right to receive nonvested Restricted Shares following termination of the Participant’s employment with the Company. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Shares of Restricted Stock issued pursuant to the Plan and may reflect distinctions based on the reasons for termination of employment.

H. VESTING OF RESTRICTED STOCK AWARDS. Unless otherwise provided in the Plan or under an Award Agreement: (1) all Awards of Restricted Stock that vest based on the passage of time which are granted to a Participant shall vest no more rapidly than pro-rata over a three (3) year period from the date of grant (the “Time-Based Restricted Stock”); and (2) all Awards of Restricted Stock that vest based on the achievement of specific measures designed to satisfy the Performance-Based Exception or other performance measures which are

granted to a Participant shall vest no more rapidly than one (1) year from the date of grant (the “Performance-Based Restricted Stock”); provided, however: (1) up to ten percent (10%) of the Time-Based Restricted Stock Awards, Performance-Based Restricted Stock Awards, or both, may by designation of the Committee (as reflected in the Restricted Stock Award Agreement), be subject to a more accelerated time-based vesting schedule or performance-based vesting schedule, as the case may be; and (2) Restricted Stock Awards which fully vest upon certain termination events as determined by the Committee and specified in the Employee’s Restricted Stock Award Agreement (or as a result of termination from the Board as a Non-Employee Director pursuant to Section VIII.I.3.f.) or a Change in Control shall not count as part of this ten percent (10%) pool.

I. ADDITIONAL PROVISIONS RELATED TO RESTRICTED STOCK AWARDS TO NON-EMPLOYEE DIRECTORS.

1. AWARD DATES. Effective as of the date specified by the Committee in its sole discretion, each Non-Employee Director will be awarded such number of Shares of Restricted Stock as determined by the Board, after consideration of the recommendation of the Committee. Non-Employee Directors may, but need not, be awarded the same number of Shares of Restricted Stock. A Non-Employee Director who is first elected to the Board on a date subsequent to the date specified by the Committee in its sole discretion will be awarded such number of Shares of Restricted Stock as of such date of election as determined by the Board, after consideration of the recommendation of the Committee.

2. DIVIDEND RIGHTS OF HOLDERS OF RESTRICTED STOCK. Notwithstanding Section VIII.F., upon issuance of a Restricted Stock Agreement, the Non-Employee Director in whose name the Restricted Stock Agreement is registered will, subject to the provisions of the Plan have the right to receive cash dividends and other cash distributions thereon.

3. PERIOD OF RESTRICTION. Restricted Stock will be subject to the restrictions set forth in Section VIII.I.4. and the other provisions of the Plan during the Period of Restriction commencing on the date as of which the Restricted Stock is awarded (the “Award Date”) and ending on the earliest of the first to occur of the following:

a. the retirement of the Non-Employee Director from the Board in compliance with the Board’s retirement policy as then in effect;

b. the termination of the Non-Employee Director’s service on the Board as a result of the Non-Employee Director’s not being nominated for reelection by the Board;

c. the termination of the Non-Employee Director’s service on the Board because of the Non-Employee Director’s resignation or failure to stand for reelection with the consent of the Company’s Board (which means approval by at least 80% of the Directors voting, with the affected Non-Employee Director abstaining);

d. the termination of the Non-Employee Director’s service on the Board because the Non-Employee Director, although nominated for reelection by the Board, is not reelected by the stockholders;

e. the termination of the Non-Employee Director’s service on the Board because of (i) the Non-Employee’s Director’s resignation at the request of the Nominating and Governance Committee of the Board (or successor committee), (ii) the Non-Employee Director’s removal by action of the stockholders or by the Board, or (iii) a Change in Control of the Company;

f. the termination of the Non-Employee Director’s service on the Board because of Disability or death; or

g. the vesting of the Restricted Stock.

Section VIII.I.3.a. through g. above are subject to the further restrictions that a removal or resignation for “Cause” will be deemed to not constitute completion of the Period of Restriction and will result in a forfeiture of

Restricted Stock not previously vested under Section VIII.I.4. For purposes of this Plan, “Cause” will be a good faith determination by the Board that the Non-Employee Director (i) failed to substantially perform his or her duties (other than a failure resulting from his or her incapacity due to physical or mental illness) after a written demand for substantial performance has been delivered to him or her by the Board, which demand specifically identifies the manner in which the Board believes such Non-Employee Director has not substantially performed his or her duties; (ii) has engaged in conduct the consequences of which are materially adverse to the Company, monetarily or otherwise; or (iii) has pleaded guilty or nolo contendere to or been convicted of a felony. The Non-Employee Director will not be deemed to have been terminated for Cause unless there will have been delivered to the Non-Employee Director a letter from the Board setting forth the reasons for the Company’s termination of the Non-Employee Director for Cause and, with respect to (i) or (ii), stating that the Non-Employee Director has failed to cure such reason for termination within thirty (30) days after the Non-Employee Director’s receipt of such notice.

4. FORFEITURE OF RESTRICTED STOCK. As of the date (“Termination Date”) a Non-Employee Director ceases to be a member of the Board for any reason, including but not limited to removal or resignation for Cause, the Non-Employee Director shall forfeit to the Company all Restricted Stock awarded to the Non-Employee Director for which the Period of Restriction has not ended pursuant to Section VIII.I.3. as of or prior to the Termination Date.

IX. RESTRICTED STOCK UNITS

A. GRANT OF RESTRICTED STOCK UNITS. Subject to the terms of the Plan, RSUs may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee. For purposes of this Article IX, the term “Participant” shall include Non-Employee Directors of the Company.

B. RESTRICTED STOCK UNIT AGREEMENT. Each RSU grant shall be evidenced by a Restricted Stock Unit Award Agreement that shall specify the Period(s) of Restriction, the number of RSUs granted, and such other provisions as the Committee may determine.

C. VALUE OF RESTRICTED STOCK UNIT. Each RSU shall have a value that is equal to the Fair Market Value of a Share on the date of grant.

D. FORM AND TIMING OF PAYMENT OF RESTRICTED STOCK UNITS. Settlement of vested RSUs may be made in the form of (i) cash, (ii) Shares or (iii) any combination of both, as determined by the Committee at the time of the grant of the RSUs, in its sole discretion. Vested RSUs shall be settled in a lump sum as soon as administratively practicable after the vesting date, but in no event later than two and one-half (2 ¹/2) months following the vesting date. The amount of such settlement shall be equal to the Fair Market Value of the RSUs on the vesting date.

E. DIVIDEND EQUIVALENTS. Each RSU shall be credited with an amount equal to the dividends paid on a Share between the date of grant and the date such RSU is paid to the Participant (if at all). Dividend equivalents shall vest, if at all, upon the same terms and conditions governing the vesting of RSUs under the Plan. Payment of the dividend equivalent shall be made at the same time as payment of the RSU and shall be made without interest or other adjustment. If the RSU is forfeited, the Participant shall have no right to dividend equivalents.

F. VOTING RIGHTS. The holders of RSUs shall have no voting rights.

G. NONTRANSFERABILITY. RSUs may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by laws of descent and distribution.

X. PERFORMANCE UNITS AND PERFORMANCE SHARES

A. GRANT OF PERFORMANCE UNITS/SHARES. Subject to the terms of the Plan, Performance Units and/or Performance Shares may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee.

B. PERFORMANCE UNIT/SHARE AGREEMENT. Each Performance Unit or Performance Share grant shall be evidenced by a Performance Unit or Performance Share Award Agreement, as the case may be, that shall specify the number of Performance Units or Performance Shares granted and such other provisions as the Committee may determine.

C. VALUE OF PERFORMANCE UNITS/SHARES. Each Performance Unit shall have an initial value that is established by the Committee 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 Committee shall set performance goals in its discretion which, depending on the extent to which they are met, will determine the number and/or value of Performance Units/Shares that will be paid out to the Participant. For purposes of this Article X, the time period during which the performance goals must be met shall be called a “Performance Period.”

D. EARNING OF PERFORMANCE UNITS/SHARES. Subject to the terms of this Plan, after the applicable Performance Period has ended, the holder of Performance Units/Shares shall be entitled to receive payout on the number and value of Performance Units/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.

E. FORM AND TIMING OF PAYMENT OF PERFORMANCE UNITS/SHARES. Payment of earned Performance Units/Shares shall be made in a single lump sum following the close of the applicable Performance Period. Subject to the terms of this Plan, the Committee, in its sole discretion, may pay earned Performance Units/Shares in the form of cash or in Shares (or in a combination thereof) which have an aggregate Fair Market Value equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period. Such Shares may be granted subject to any restrictions deemed appropriate by the Committee. The determination of the Committee 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. Payment shall be made no later than two and one-half (2 ¹/2) months following the close of the Performance Period.

F. SEPARATION FROM SERVICE DUE TO DEATH OR DISABILITY. In the event the Participant incurs a Separation From Service by reason of death or Disability during a Performance Period, the Participant shall not receive a payout of the Performance Units/Shares, unless determined otherwise by the Committee or set forth in the Participant’s Award Agreement.

Payment of earned Performance Units/Shares shall be made at a time specified by the Committee in its sole discretion and set forth in the Participant’s Award Agreement.

G. TERMINATION OF EMPLOYMENT FOR OTHER REASONS. In the event that a Participant’s employment terminates for any reason other than those reasons set forth in Section X.F. herein, all Performance Units/Shares intended to qualify for the Performance-Based Exception shall be forfeited by the Participant to the Company.

H. NONTRANSFERABILITY. Except as otherwise provided in a Participant’s Award Agreement, Performance Units/Shares may not be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, except as otherwise provided in a Participant’s Award Agreement, a Participant’s rights under the Plan shall be exercisable during the Participant’s lifetime only by the Participant or the Participant’s legal representative.

I. NO DIVIDEND AND VOTING RIGHTS. Participants will not be entitled to receive any dividends declared with respect to Shares which have been earned in connection with grants of Performance Units and/or Performance Shares, but not yet distributed to Participants nor shall Participants have voting rights with respect to such Shares.

XI. PERFORMANCE MEASURES

Unless and until the Committee proposes for stockholder vote and the Company’s stockholders approve a change in the general performance measures set forth in this Article XI, the attainment of which may determine the degree of payout and/or vesting with respect to Awards to Covered Employees which measures are designed to qualify for the Performance-Based Exception, the performance measure(s) to be used for purposes of such grants may be measured at the Company level, at a Subsidiary or Affiliate level, or at an operating unit level and shall be chosen from among the following: net income either before or after taxes (including adjusted net income), share price, earnings per share (basic or diluted), total stockholder return, return on assets, return on equity, operating income, return on capital or investment, cash flow or adjusted cash flow from operations, economic value added or adjusted cash flow per Share (net income plus or minus change in operating assets and liabilities), debt level, cost reduction targets, equity ratios, capital efficiency (adjusted EBITDA divided by production and divided by average funding and development cost per unit), operating and general and administrative expense per Mcfe (the sum of total lease operating expense, exploration general and administrative expense and corporate general and administrative expense divided by Mcfe (mcf equivalent for gas and oil)), average reserve replacement ratio (the sum of extensions and discoveries, revisions in previous estimates and purchase of reserves divided by the sum of the same), production (actual production volume for a specified period of time) (including, but not limited to, any or all of such measures in comparison to the Company’s competitors, the industry or some other comparator group), amount of the oil and gas reserves, oil and gas reserve additions, and costs of finding oil and gas reserves.

The Committee shall have the discretion to adjust the determinations of the degree of attainment of the preestablished performance goals; provided, however, that Awards which are designed to qualify for the Performance-Based Exception, and which are held by Covered Employees, may not be adjusted upward (the Committee shall retain the discretion to adjust such Awards downward).

In the event that applicable tax and/or securities laws or exchange listing standards change to permit Committee discretion to alter the governing performance measures without obtaining stockholder approval of such changes, the Committee shall have sole discretion to make such changes without obtaining stockholder approval. In addition, in the event that the Committee determines that it is advisable to grant Awards which shall not qualify for the Performance-Based Exception, the Committee may make such grants without satisfying the requirements of Code Section 162(m).

In the case of any Award which is granted subject to the condition that a specified performance measure be achieved, no payment under such Award shall be made prior to the time that the Committee certifies in writing that the performance measure has been satisfied, in accordance with Internal Revenue Service requirements. No such certification is required, however, in the case of an Award that is based solely on an increase in the value of a Share from the date such Award was made.

XII. BENEFICIARY DESIGNATION

Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under the Plan is to be paid in case of his or her death before he or she 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 Company, 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 designated beneficiary, benefits remaining unpaid at the Participant’s death shall be paid to the Participant’s estate.

XIII. DEFERRALS

The Committee may permit or require a Participant to defer such Participant’s receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant by virtue of the exercise of an Option or SAR, the lapse or waiver of restrictions with respect to Restricted Stock or Restricted Stock Units, or the satisfaction of any requirements or goals with respect to Performance Units/Shares. If any such deferral election is required or permitted, the Committee shall, in its sole discretion, establish rules and procedures for such payment deferrals, provided, however, all deferrals shall be made in accordance with all applicable requirements of Code Section 409A or any guidance promulgated thereunder.

XIV. RIGHTS OF EMPLOYEES

A. EMPLOYMENT. Nothing in the Plan shall interfere with or limit in any way the right of the Company to terminate any Participant’s employment at any time, nor confer upon any Participant any right to continue in the employ of the Company.

B. PARTICIPATION. No Employee 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.

XV. AMENDMENT, MODIFICATION, TERMINATION AND ADJUSTMENTS

A. AMENDMENT, MODIFICATION, AND TERMINATION. Subject to the terms of the Plan, the Board, upon recommendation of the Committee, may at any time and from time to time, alter, amend, suspend or terminate the Plan in whole or in part for any purpose which the Committee deems appropriate and that is otherwise consistent with Code Section 409A; provided, however, no amendment shall, without shareholder approval, (i) materially increase the benefits accruing to Participants under the Plan; (ii) materially increase the number of securities which may be issued under the Plan; or (iii) materially modify the requirements for participation in the Plan.

Except in connection with a corporate transaction involving the Company (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the terms of outstanding Awards may not be amended to reduce the exercise price of outstanding Options or SARs or cancel outstanding Options or SARs in exchange for cash, other awards or Options or SARs with an exercise price that is less than the exercise price of the original Options or SARs without shareholder approval.

B. ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR NONRECURRING EVENTS. The Committee 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 IV.C. hereof) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan; provided that unless the Committee determines otherwise, no such adjustment shall be authorized to the extent that such authority would be inconsistent with the Plan or Awards meeting the requirements of Code Sections 162(m) and 409A, as from time to time amended.

C. AWARDS PREVIOUSLY GRANTED. Notwithstanding any other provision of the Plan to the contrary (but subject to Section XV.B. hereof), no termination, amendment or modification of the Plan shall adversely affect in any material way any Award previously granted under the Plan without the written consent of the Participant holding such Award.

D. COMPLIANCE WITH CODE SECTION 162(m). At all times when Code Section 162(m) is applicable, all Awards granted under this Plan shall comply with the requirements of Code Section 162(m); provided, however, that in the event the Committee determines that such compliance is not desired with respect to any Award or Awards available for grant under the Plan, then compliance with Code Section 162(m) will not be required. In addition, in the event that changes are made to Code Section 162(m) to permit greater flexibility with respect to any Award or Awards available under the Plan, the Committee may, subject to this Article XV, make any adjustments it deems appropriate consistent with the changes made to Code Section 162(m).

XVI. PAYMENT OF PLAN AWARDS AND CONDITIONS THEREON

A. EFFECT OF COMPETITIVE ACTIVITY. Anything contained in the Plan to the contrary notwithstanding, unless otherwise covered in an employment agreement by and between the Company and the Participant, with respect to any Participant who is an Employee, if the employment of any Participant shall terminate, for any reason other than death, while any Award to such Participant is outstanding hereunder, and such

Participant has not yet received the Shares covered by such Award or otherwise received the full benefit of such Award, such Participant, if otherwise entitled thereto, shall receive such Shares or benefit only if, during the entire period from the date of such Participant’s termination to the date of such receipt, such Participant shall have earned such Award by: (i) making himself or herself available, upon request, at reasonable times and upon a reasonable basis, to consult with, supply information to, and otherwise cooperate with the Company or any Subsidiary or Affiliate thereof with respect to any matter that shall have been handled by him or her or under his or her supervision while he or she was in the employ of the Company or of any Subsidiary or Affiliate thereof; and (ii) refraining from engaging in any activity within any county or parish, or adjacent to any county or parish, in which the Company owns any oil and gas interests that is directly or indirectly in competition with any gas, exploration and production activities, including oil and gas leasing or drilling activities of the Company or any Subsidiary or Affiliate thereof for a period of one (1) year following his or her termination of employment.

B. NONFULFILLMENT OF COMPETITIVE ACTIVITY CONDITIONS; WAIVERS UNDER THE PLAN. In the event of a Participant’s nonfulfillment of any condition set forth in Section XVI.A. hereof, such Participant’s rights under any Award shall be forfeited and canceled forthwith; provided, however, that the nonfulfillment of such condition may at any time (whether before, at the time of, or subsequent to termination of employment) be waived by the Committee upon its determination that in its sole judgment there shall not have been and will not be any substantial adverse effect upon the Company or any Subsidiary or Affiliate thereof by reason of the nonfulfillment of such condition.

XVII. CHANGE IN CONTROL

A. TREATMENT OF OUTSTANDING AWARDS. Notwithstanding any provisions in the Participant’s Employment Agreement to the contrary, but subject to Section XVII.B. herein or the Plan governing the particular Award, upon the occurrence of a Change in Control:

1. any and all Options and SARs granted hereunder shall become immediately exercisable;

2. any Periods of Restriction and restrictions imposed on Restricted Stock or RSUs which are not intended to qualify for the Performance-Based Exception shall lapse; and

3. any Award intended to qualify for the Performance-Based Exception shall be earned in accordance with the applicable Award Agreement.

B. TERMINATION, AMENDMENT AND MODIFICATIONS OF CHANGE-IN-CONTROL PROVISIONS. Notwithstanding any other provision of the Plan or any Award Agreement provision, the provisions of this Article XVII may not be terminated, amended or modified on or after the date of an event, commencing upon material discussions by the Board respecting a possible transaction that would result in a Change in Control, which is likely to give rise to a Change in Control to affect adversely any Award theretofore granted under the Plan without the prior written consent of the Participant with respect to said Participant’s outstanding Awards.

XVIII. TAX PROVISIONS

A. TAX WITHHOLDING. The Company shall have the power and the right to deduct or withhold, or require a Participant who is an Employee to remit to the Company, an amount sufficient 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.

B. SHARE WITHHOLDING. With respect to withholding required upon the exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock or Restricted RSUs, upon achievement of the performance goals on Performance Shares or Performance Units or upon any other taxable event arising as a result of Awards granted hereunder, Participants who are Employees may elect, subject to the approval of the Committee, to satisfy the withholding requirement, in whole or in part, by having the Company withhold Shares having a Fair Market Value on the date the tax is to be determined at least equal to the minimum, but not more than the maximum, statutory tax which could be imposed on the transaction. All such elections shall be irrevocable, made in writing,

and signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

C. REQUIREMENT OF NOTIFICATION OF CODE SECTION 83(b) ELECTION. If any Participants shall make an election under Code Section 83(b) (to include in gross income in the year of transfer the amounts specified in Code Section 83(b)) or under a similar provisions of the laws of a jurisdiction outside the United States, such Participant shall notify the Company of such election within ten (10) days after filing notice of the election with the Internal Revenue Service or other government authority, in addition to any filing and notification required pursuant to regulations issued under Code Section 83(b) or other applicable provision.

D. REQUIREMENT OF NOTIFICATION UPON DISQUALIFYING DISPOSITION UNDER CODE SECTION 421(b). If any Participant shall make any disposition of shares of stock delivered pursuant to the exercise of an Incentive Stock Option under the circumstances described in Code Section 421(b) (relating to certain disqualifying dispositions), such Participant shall notify the Company of such disposition within ten (10) days thereof.

XIX. INDEMNIFICATION

Each person who is or shall have been a member of the Committee, or of the Board, shall be indemnified and held harmless by the Company against and from any loss, cost, liability or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such action, suit or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Articles of Incorporation or Bylaws, as a matter of law or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

XX. SUCCESSORS

All obligations of the Company under the 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 or assets of the Company.

XXI. LEGAL CONSTRUCTION

A. GENDER AND NUMBER. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular, and the singular shall include the plural.

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

C. REQUIREMENTS OF LAW. The granting of Awards and the issuance of Shares under the 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.

D. SECURITIES LAW COMPLIANCE. With respect to Insiders, transactions under this Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent any provision of the Plan or action by the Committee fails to so comply, it shall be deemed null and void, to the extent permitted by law and deemed advisable by the Committee.

E. CODE SECTION 409A COMPLIANCE. Notwithstanding any other provision of this Plan to the contrary, all Awards under this Plan that are subject to Code Section 409A shall be designed and administered in a manner that does not result in the imposition of tax or penalties under Code Section 409A. Accordingly, Awards under this Plan that are subject to Code Section 409A shall comply with the following requirements, as applicable.

1. Distribution to Specified Employees Upon Separation from Service. To the extent that payment under an Award which is subject to Code Section 409A is due to a Specified Employee on account of the Specified Employee’s Separation from Service from the Company or its Affiliate or Subsidiary, such payment shall be delayed until the first day of the seventh (7th) month following such Separation from Service (or as soon as practicable thereafter). The Committee, in its discretion, may provide in the Award document for the payment of interest at a rate set by the Committee for such six-month period. In the event that a payment under an Award is exempt from Code Section 409A, payment shall be made to a Specified Employee without any such six-month delay.

2. No Acceleration of Payment. To the extent that an Award is subject to Code Section 409A, payment under such Award shall not be accelerated from the date(s) specified in the Award documents as of the date of grant.

3. Subsequent Delay in Payment. To the extent that an Award is subject to Code Section 409A, payment under such Award shall not be deferred beyond the dates specified in the Award document as of the date of grant, unless the Committee or Participant, as the case may be, makes the decision to delay payment at least one year prior to the scheduled payment date, and payment is delayed at least five (5) years.

F. GOVERNING LAW. To the extent not preempted by federal law, the Plan, and all agreements hereunder, shall be construed in accordance with and governed by the laws of the State of Colorado.
