IV. ADMINISTRATION (a) Composition of Committee. The Plan shall be administered by a committee which shall be (i) appointed by the Board and (ii) constituted so as to permit the Plan to comply with Rule 16b-3. (b) Powers. The Committee shall have sole authority, in its discretion, to determine which employees of the Company and its Subsidiaries shall receive an Award, the time or times when such Award shall be made, whether an Incentive Stock Option, nonqualified Option or Stock Appreciation Right shall be granted, the number of shares of Common Stock which may be issued under each Option, Stock Appreciation Right and Restricted Stock Award, and the value of each Performance Share Award and Stock Value Equivalent Award. In making such determinations the Committee may take into account the nature of the services rendered by the respective employees, their present and potential contribution to the Company's success and such other factors as the Committee in its discretion shall deem relevant. (c) Additional Powers. The Committee shall have such additional powers as are delegated to it by the other provisions of the Plan. Subject to the express provisions of the Plan, the Committee is authorized to construe the Plan and the respective agreements executed thereunder, to prescribe such rules and regulations relating to the Plan as it may deem advisable to carry out the Plan, and to determine the terms, restrictions and provisions of each Award, including such terms, restrictions and provisions as shall be requisite in the judgment of the Committee etermuse designated Options to qualify as Incentive Stock Options, and to make all other determinations necessary or advisable for administering the Plan. The Committee may correcn any defect or supply any omission or reconcile any inconsistency in any agreement relating to an Award in the manner and to the extent it shall deem expedient to carry it into effecn. The determinations of the Committee on the matters referred to in this Article IV shall be conclusive. V. GRANT OF OPTIONS, STOCK APPRECIATION RIGHTS, RESTRICTED STOCK AWARDS, PERFORMANCE SHARE AWARDS AND STOCK VALUE EQUIVALENT AWARDS; SHARES SUBJECT TO THE PLAN (a) Award Limits. The Committee may from time to time grant Awards to one or more employees determined by it to be eligible for participation in the Plan in accordance with the provisions of Article VI. The aggregate number of shares of Common Stock that may be issued under the Plan shall not exceed 5,500,000 shares and no more than 1,600,000 of such shares may be issued in the form of Restricted Stock Awards. Notwithstanding anything contained herein to the contrary, the number of Option shares or Stock Appreciation Rights, singly or in combination, granted to any employee in any one calendar year shall not in the aggregate exceed 500,000. Any of such shares which remain unissued and which are not subject to outstanding Options or Awards at the termination of the Plan shall cease to be subject to the Plan, but, until termination of the Plan, the Company shall at all times reserve a sufficient number of shares to meet the requirements of the Plan. Shares shall be deemed to have been issued under the Plan only to the extent actually issued and delivered pursuant to an Award. To the extent that an Award lapses or the rights of its Holder terminate or the Award is paid in cash, any shares of Common Stock subject to such Award shall again be available for the grant of an Award. The aggregate number of shares which may be issued under the Plan shall be subject to adjustment in the same manner as provided in Article XII with respect to shares of Common Stock subject to Options then outstanding. Separate stock certificates shall be issued by the Company for those shares acquired pursuant to the exercise of an Incentive Stock Option and for those shares acquired pursuant to the exercise of any Option which does not constitute an Incentive Stock Option. (b) Stock Offered. The stock to be offered pursuant to the grant of an Award may be authorized but unissued Common Stock or Common Stock previously issued and outstanding and reacquired by the Company. VI. ELIGIBILITY Awards made pursuant to the Plan may be granted only to individuals who, at the time of grant, are key employees of the Company or any Parent Corporation or Subsidiary of the Company. Awards may not be granted to any director of the Company who is not an employee of the Company or to any member of the Committee. An Award made pursuant to the Plan may be granted on more than one occasion to the same person, and such Award may include an Incentive Stock Option, an Option which is not an Incentive Stock Option, an Award of Stock Appreciation Rights, a Restricted Stock Award, a Performance Share Award, a Stock Value Equivalent Award or any combination thereof. Each Award shall be evidenced by a written instrument duly executed by or on behalf of the Company. VII. STOCK OPTIONS (a) Stock Option Agreement. Each Option shall be evidenced by an Option Agreement between the Company and the Optionee which shall contain such terms and conditions as may be approved by the Committee. The terms and conditions of the respective Option Agreements need not be identical. Specifically, an Option Agreement may provide for the payment of the option price, in whole or in part, by the delivery of a number of shares of Common Stock (plus cash if necessary) having a Fair Market Value equal to such option price. Each Option Agreement shall provide that the Option may not be exercised earlier than six months from the date of grant and shall specify the effecn of termination of employment on the exercisability of the Option. (b) Option Period. The term of each Option shall be as specified by the Committee at the date of grant. (c) Limitations on Exercise of Option. An Option shall be exercisable in whole or in such installments and at such times as determined by the Committee. (d) Special Limitations on Incentive Stock Options. To the extent that the aggregate Fair Market Value (determined at the time the respective Incentive Stock Option is granted) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by an individual during any calendar year under all incentive stock option plans of the Company and its Parent Corporation and Subsidiaries exceeds $100,000, such excess Incentive Stock Options shall be treated as Options which do not constitute Incentive Stock Options. The Committee shall determine, in accordance with applicable provisions of the Code, Treasury Regulations and other administrative pronouncements, which of an Optionee's Incentive Stock Option will not constitute Incentive Stock Options because of such limitation and shall notify the Optionee of such determination as soon as practicable after such determination. No Incentive Stock Option shall be granted to an individual if, at the time the Option is granted, such individual owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of its Parent Corporation or a Subsidiary, within the meaning of section 422(b)(6) of the Code, unless (i) at the time such Option is granted the option price is at least 110% of the Fair Market Value of the Common Stock subject to the Option and (ii) such Option by its terms is not exercisable after the expiration of five years from the date of grant. (e) Option Price. The purchase price of Common Stock issued under each Option shall be determined by the Committee, but such purchase price shall not be less than the Fair Market Value of Common Stock subject to the Option on the date the Option is granted. (f) Options and Rights in Substitution for Stock Options Granted by Other Corporations. Options and Stock Appreciation Rights may be granted under the Plan from time to time in substitution for stock options held by employees of corporations who become, or who became prior to the effecnive date of the Plan, key employees of the Company or of any Subsidiary as a result of a merger or consolidation of the employing corporation with the Company or such Subsidiary, or the acquisition by the Company or a Subsidiary of all or a portion of the assets of the employing corporation, or the acquisition by the Company or a Subsidiary of stock of the employing corporation with the result that such employing corporation becomes a Subsidiary. VIII. STOCK APPRECIATION RIGHTS (a) Stock Appreciation Rights. A Stock Appreciation Right is the right to receive an amount equal to the Spread with respect to a share of Common Stock upon the exercise of such Stock Appreciation Right. Stock Appreciation Rights may be granted in connection with the grant of an Option, in which case the Option Agreement will provide that exercise of Stock Appreciation Rights will result in the surrender of the right to purchase the shares under the Option as to which the Stock Appreciation Rights were exercised. Alternatively, Stock Appreciation Rights may be granted independently of Options in which case each Award of Stock Appreciation Rights shall be evidenced by a Stock Appreciation Rights Agreement between the Company and the Holder which shall contain such terms and conditions as may be approved by the Committee. The terms and conditions of the respective Stock Appreciation Rights Agreements need not be identical. The Spread with respect to a Stock Appreciation Right may be payable either in cash, shares of Common Stock with a Fair Market Value equal to the Spread or in a combination of cash and shares of Common Stock. With respect to Stock Appreciation Rights that are subject to Section 16 of the Exchange Act, however, the Committee shall, except as provided in Paragraphs (e) and (f) of Article XII, retain sole discretion (i) to determine the form in which payment of the Stock Appreciation Right will be made (i.e., cash, securities or any combination thereof) or (ii) to approve an election by a Holder to receive cash in full or partial settlement of Stock Appreciation Rights. Upon the exercise of any Stock Appreciation Rights granted hereunder, the number of shares reserved for issuance under the Plan shall be reduced only to the extent that shares of Common Stock are actually issued in connection with the exercise of such Right. Each Stock Appreciation Rights Agreement shall provide that the Stock Appreciation Rights may not be exercised earlier than six months from the date of grant and shall specify the effecn of termination of employment on the exercisability of the Stock Appreciation Rights. (b) Exercise Price. The exercise price of each Stock Appreciation Right shall be determined by the Committee, but such exercise price shall not be less than the Fair Market Value of a share of Common Stock on the date the Stock Appreciation Right is granted. (c) Exercise Period. The term of each Stock Appreciation Right shall be as specified by the Committee at the date of grant. (d) Limitations on Exercise of Stock Appreciation Right. A Stock Appreciation Right shall be exercisable in whole or in such installments and at such times as determined by the Committee. IX. RESTRICTED STOCK AWARDS (a) Restricted Period To Be Established by the Committee. At the time a Restricted Stock Award is made, the Committee shall establish a period of time (the "Restriction Period") applicable to such Award; provided, however, that, except as set forth below and as permitted by Paragraph (b) of this Article IX, such Restriction Period shall not be less than three (3) years from the date of grant (the "Minimum Criteria"). An award which provides for the lapse of restrictions on shares applicable to such Award in equal annual installments over a period of at least three (3) years from the date of grant shall be deemed to meet the Minimum Criteria. The foregoing notwithstanding, with respect to Restricted Stock Awards of up to an aggregate 275,000 shares (subject to adjustment as set forth in Article XII), the Minimum Criteria shall not apply and the Committee may establish such lesser Restriction Periods applicable to such Awards as it shall determine in its discretion. Subject to the foregoing, each Restricted Stock Award may have a different Restriction Period, in the discretion of the Committee. The Restriction Period applicable to a particular Restricted Stock Award shall not be changed except as permitted by Paragraph (b) of this Article or by Article XII. (b) Other Terms and Conditions. Common Stock awarded pursuant to a Restricted Stock Award shall be represented by a stock certificate registered in the name of the Holder of such Restricted Stock Award or, at the option of the Company, in the name of a nominee of the Company. The Holder shall have the right to receive dividends during the Restriction Period, to vote the Common Stock subject thereto and to enjoy all other stockholder rights, except that (i) the Holder shall not be entitled to possession of the stock certificate until the Restriction Period shall have expired, (ii) the Company shall retain custody of the stock during the Restriction Period, (iii) the Holder may not sell, transfer, pledge, exchange, hypothecate or otherwise dispose of the stock during the Restriction Period and (iv) a breach of the terms and conditions established by the Committee pursuant to the Restricted Stock Award shall cause a forfeiture of the Restricted Stock Award. At the time of such Award, the Committee may, in its sole discretion, prescribe additional terms, conditions or restrictions relating to Restricted Stock Awards, including, but not limited to, rules pertaining to the termination of employment (by retirement, disability, death or otherwise) of a Holder prior to expiration of the Restriction Period. (c) Payment for Restricted Stock. A Holder shall not be required to make any payment for Common Stock received pursuant to a Restricted Stock Award, except to the extent otherwise required by law and except that the Committee may, in its discretion, charge the Holder an amount in cash not in excess of the par value of the shares of Common Stock issued under the Plan to the Holder. (d) Miscellaneous. Nothing in this Article shall prohibit the exchange of shares issued under the Plan (whether or not then subject to a Restricted Stock Award) pursuant to a plan of reorganization for stock or securities in the Company or another corporation a party to the reorganization, but the stock or securities so received for shares then subject to the restrictions of a Restricted Stock Award shall become subject to the restrictions of such Restricted Stock Award. Any shares of stock received as a result of a stock split or stock dividend with respect to shares then subject to a Restricted Stock Award shall also become subject to the restrictions of the Restricted Stock Award. X. PERFORMANCE SHARE AWARDS (a) Performance Period. The Committee shall establish, with respect to and at the time of each Performance Share Award, a performance period over which the performance applicable to the Performance Share Award of the Holder shall be measured. (b) Performance Share Awards. Each Performance Share Award may have a maximum value established by the Committee at the time of such Award. (c) Performance Measures. A Performance Share Award may be awarded to an employee contingent upon future performance of the employee, the Company or any Subsidiary, division or department thereof by or in which he is employed during the performance period, the Fair Market Value of Common Stock or the increase thereof during the performance period, combinations thereof, or such other provisions as the Committee may determine to be appropriate. The Committee shall establish the performance measures applicable to such performance prior to the beginning of the performance period but subject to such later revisions as the Committee shall deem appropriate to reflect significant, unforeseen events or changes. (d) Awards Criteria. In determining the value of Performance Share Awards, the Committee may take into account an employee's responsibility level, performance, potential, other Awards and such other considerations as it deems appropriate. (e) Payment. Following the end of the performance period, the Holder of a Performance Share Award shall be entitled to receive payment of an amount, not exceeding the maximum value of the Performance Share Award, if any, based on the achievement of the performance measures for such performance period, as determined by the Committee in its sole discretion. Payment of a Performance Share Award (i) may be made in cash, Common Stock or a combination thereof, as determined by the Committee in its sole discretion, (ii) shall be made in a lump sum or in installments as prescribed by the Committee in its sole discretion and (iii) to the extent applicable, shall be based on the Fair Market Value of the Common Stock on the payment date. If a payment of cash is to be made on a deferred basis, the Committee shall establish whether interest shall be credited, the rate thereof and any other terms and conditions applicable thereto. (f) Termination of Employment. The Committee shall determine the effect of termination of employment during the performance period on an employee's Performance Share Award. XI. STOCK VALUE EQUIVALENT AWARDS (a) Stock Value Equivalent Awards. Stock Value Equivalent Awards are rights to receive an amount equal to the Fair Market Value of shares of Common Stock or rights to receive an amount equal to any appreciation or increase in the Fair Market Value of Common Stock over a specified period of time, which vest over a period of time as established by the Committee, without payment of any amounts by the Holder thereof (except to the extent otherwise required by law) or satisfaction of any performance criteria or objectives. Each Stock Value Equivalent Award may have a maximum value established by the Committee at the time of such Award. (b) Award Period. The Committee shall establish, with respect to and at the time of each Stock Value Equivalent Award, a period over which the Award shall vest with respect to the Holder. (c) Awards Criteria. In determining the value of Stock Value Equivalent Awards, the Committee may take into account an employee's responsibility level, performance, potential, other Awards and such other considerations as it deems appropriate. (d) Payment. Following the end of the determined period for a Stock Value Equivalent Award, the Holder of a Stock Value Equivalent Award shall be entitled to receive payment of an amount, not exceeding the maximum value of the Stock Value Equivalent Award, if any, based on the then vested value of the Award. Payment of a Stock Value Equivalent Award (i) shall be made in cash, (ii) shall be made in a lump sum or in installments as prescribed by the Committee in its sole discretion and (iii) shall be based on the Fair Market Value of the Common Stock on the payment date. Cash dividend equivalents may be paid during, or may be accumulated and paid at the end of, the determined period with respect to a Stock Value Equivalent Award, as determined by the Committee. If payment of cash is to be made on a deferred basis, the Committee shall establish whether interest shall be credited, the rate thereof and any other terms and conditions applicable thereto. (e) Termination of Employment. The Committee shall determine the effect of termination of employment during the applicable vesting period on an employee's Stock Value Equivalent Award. XII. RECAPITALIZATION OR REORGANIZATION (a) Except as hereinafter otherwise provided, in the event of any recapitalization, reorganization, merger, consolidation, combination, exchange, stock dividend, stock split, extraordinary dividend or divestiture (including a spin-off) or any other change in the corporate structure or shares of Common Stock occurring after the date of the grant of an Award, the Committee may, in its discretion, make such adjustment as to the number and price of shares of Common Stock or other consideration subject to such Awards as the Committee shall deem appropriate in order to prevent dilution or enlargement of rights of the Holders. (b) The existence of the Plan and the Awards granted hereunder shall not affect in any way the right or power of the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company's capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities having any priority or preference with respect to or affecting Common Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any other corporate act or proceeding. (c) The shares with respect to which Options may be granted are shares of Common Stock as presently constituted, but if, and whenever, prior to the expiration of an Option theretofore granted, the Company shall effect a subdivision or consolidation of shares of Common Stock or the payment of a stock dividend on Common Stock without receipt of consideration by the Company, the number of shares of Common Stock with respect to which such Option may thereafter be exercised (i) in the event of an increase in the number of outstanding shares shall be proportionately increased, and the purchase price per share shall be proportionately reduced, and (ii) in the event of a reduction in the number of outstanding shares shall be proportionately reduced, and the purchase price per share shall be proportionately increased. (d) If the Company recapitalizes or otherwise changes its capital structure, thereafter upon any exercise of an Option theretofore granted the Optionee shall be entitled to purchase under such Option, in lieu of the number of shares of Common Stock as to which such Option shall then be exercisable, the number and class of shares of stock and securities and the cash and other property to which the Optionee would have been entitled pursuant to the terms of the recapitalization if, immediately prior to such recapitalization, the Optionee had been the holder of record of the number of shares of Common Stock then covered by such Option. (e) In the event of a Corporate Change, then no later than (i) two business days prior to any Corporate Change referenced in Clause (i), (ii), (iii) or (v) of the definition thereof or (ii) ten business days after any Corporate Change referenced in Clause (iv) of the definition thereof, the Committee, acting in its sole discretion without the consent or approval of any Optionee, shall act to effect one or more of the following alternatives with respect to outstanding Options which acts may vary among individual Optionees, may vary among Options held by individual Optionees and, with respect to acts taken pursuant to Clause (i) above, may be contingent upon effectuation of the Corporate Change: (A) accelerate the time at which Options then outstanding may be exercised so that such Options may be exercised in full for a limited period of time on or before a specified date (before or after such Corporate Change) fixed by the Committee, after which specified date all unexercised Options and all rights of Optionees thereunder shall terminate, (B) require the mandatory surrender to the Company by selected Optionees of some or all of the outstanding Options held by such Optionees (irrespective of whether such Options are then exercisable under the provisions of the Plan) as of a date (before or after such Corporate Change) specified by the Committee, in which event the Committee shall thereupon cancel such Options and pay to each Optionee an amount of cash per share equal to the excess, if any, of the Change of Control Value of the shares subject to such Option over the exercise price(s) under such Options for such shares, (C) make such adjustments to Options then outstanding as the Committee deems appropriate to reflect such Corporate Change (provided, however, that the Committee may determine in its sole discretion that no adjustment is necessary to Options then outstanding) or (D) provide that thereafter upon any exercise of an Option theretofore granted the Optionee shall be entitled to purchase under such Option, in lieu of the number of shares of Common Stock as to which such Option shall then be exercisable, the number and class of shares of stock or other securities or property (including, without limitation, cash) to which the Optionee would have been entitled pursuant to the terms of the agreement of merger, consolidation or sale of assets or plan of liquidation and dissolution if, immediately prior to such merger, consolidation or sale of assets or any distribution in liquidation and dissolution of the Company, the Optionee had been the holder of record of the number of shares of Common Stock then covered by such Option. (f) In the event of a Corporate Change, then no later than (i) two business days prior to any Corporate Change referenced in Clause (i), (ii), (iii) or (v) of the definition thereof or (ii) ten business days after any Corporate Change referenced in Clause (iv) of the definition thereof, the Committee, acting in its sole discretion without the consent or approval of any Holder of a Stock Appreciation Right, shall act to effect one or more of the following alternatives with respect to outstanding Stock Appreciation Rights which acts may vary among individual Holders, may vary among Stock Appreciation Rights held by individual Holders and, with respect to acts taken pursuant to Clause (ii) above, may be contingent upon effectuation of the Corporate Change: (A) accelerate the time at which Stock Appreciation Rights then outstanding may be exercised so that such Stock Appreciation Rights may be exercised in full for a limited period of time on or before a specified date (before or after such Corporate Change) fixed by the Committee, after which specified date all unexercised Stock Appreciation Rights and all rights of Holders thereunder shall terminate, (B) require the mandatory surrender to the Company by selected Holders of Stock Appreciation Rights of some or all of the outstanding Stock Appreciation Rights held by such Holders (irrespective of whether such Stock Appreciation Rights are then exercisable under the provisions of the Plan) as of a date (before or after such Corporate Change) specified by the Committee, in which event the Committee shall thereupon cancel such Stock Appreciation Rights and pay to each Holder an amount of cash equal to the Spread with respect to such Stock Appreciation Rights with the Fair Market Value of the Common Stock at such time to be deemed to be the Change of Control Value or (C) make such adjustments to Stock Appreciation Rights then outstanding as the Committee deems appropriate to reflect such Corporate Change (provided, however, that the Committee may determine in its sole discretion that no adjustment is necessary to Stock Appreciation Rights then outstanding). (g) Except as hereinbefore expressly provided, the issuance by the Company of shares of stock of any class or securities convertible into shares of stock of any class, for cash, property, labor or services, upon direct sale, upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, and in any case whether or not for fair value, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Common Stock subject to Options or Stock Appreciation Rights theretofore granted, the purchase price per share of Common Stock subject to Options or the calculation of the Spread with respect to Stock Appreciation Rights. (h) Plan provisions to the contrary notwithstanding, with respect to any Stock Value Equivalent Awards which have been approved but which are unpaid at the time a Corporate Change occurs, the Committee may, in its discretion, provide (i) for full vesting of such Awards as of the date of such Corporate Change and (ii) for payment of the then value of such Awards as soon as administratively feasible following the Corporate Change with the value of such Awards to be based on the Change of Control Value of the Common Stock.

Neither the adoption of the Plan nor any action of the Board or of the Committee shall be deemed to give an employee any right to be granted an Option to purchase Common Stock, a Stock Appreciation Right, a right to a Restricted Stock Award or a right to a Performance Share Award or Stock Value Equivalent Award or any other rights hereunder except as may be evidenced by an Award or by an Option Agreement duly executed on behalf of the Company, and then only to the extent of and on the terms and conditions expressly set forth therein. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of funds or assets to assure the payment of any Award. (b) No Employment Rights Conferred. Nothing contained in the Plan or in any Award made hereunder shall (i) confer upon any employee any right with respect to continuation of employment with the Company or any Subsidiary or (ii) interfere in any way with the right of the Company or any Subsidiary to terminate his or her employment at any time. (c) Other Laws; Withholding. The Company shall not be obligated to issue any Common Stock pursuant to any Award granted under the Plan at any time when the offering of the shares covered by such Award has not been registered under the Securities Act of 1933 and such other state and federal laws, rules or regulations as the Company or the Committee deems applicable and, in the opinion of legal counsel for the Company, there is no exemption from the registration requirements of such laws, rules or regulations available for the issuance and sale of such shares. No fractional shares of Common Stock shall be delivered, nor shall any cash in lieu of fractional shares be paid. The Company shall have the right to deduct in connection with all Awards any taxes required by law to be withheld and to require any payments necessary to enable it to satisfy its withholding obligations. The Committee may permit the Holder of an Award to elect to surrender, or authorize the Company to withhold, shares of Common Stock (valued at their Fair Market Value on the date of surrender or withholding of such shares) in satisfaction of the Company's withholding obligation, subject to such restrictions as the Committee deems necessary to satisfy the requirements of Rule 16b-3. (d) No Restriction on Corporate Action. Nothing contained in the Plan shall be construed to prevent the Company or any Subsidiary from taking any corporate action which is deemed by the Company or such Subsidiary to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Award made under the Plan. No employee, beneficiary or other person shall have any claim against the Company or any Subsidiary as a result of any such action. (e) Restrictions on Transfer. An Award shall not be transferable otherwise than by will or the laws of descent and distribution and shall be exercisable during the lifetime of the Holder only by such Holder or the Holder's guardian or legal representative. The Option Agreement, Stock Appreciation Rights Agreement or other written instrument evidencing an Award shall specify the effect of the death of the Holder on the Award. (f) Rule 16b-3. It is intended that the Plan and any grant of an Award made to a person subject to Section 16 of the Exchange Act meet all of the requirements of Rule 16b-3. If any provision of the Plan or any such Award would disqualify the Plan or such Award under, or would otherwise not comply with, Rule 16b-3, such provision or Award shall be construed or deemed amended to conform to Rule 16b-3. (g) Governing Law. This Plan shall be construed in accordance with the laws of the State of Texas, except to the extent that it implicates matters which are the subject of the General Corporation Law of the State of Delaware which matters shall be governed by the latter law.
