to grant Awards, to determine the terms and conditions applicable to Awards, to determine the persons to whom, and the time or times at which, Awards shall be granted and the number of Common Shares to be covered by each grant; to determine the terms and provisions of the Award Agreements entered into in connection with Awards under the Plan; to interpret the Plan; to prescribe, amend and rescind rules and regulations relating to the Plan; and to make all other determinations provided for in the Plan, or deemed necessary or advisable for the administration of the Plan.

Subject to the discretion of the Committee, Awards may be granted to any Employee of the Company and its Affiliates, a director of the Company, or a non-employee who provides service to the Company or its Affiliates, except that a non-employee shall not be granted an Incentive Stock Option. In determining the Employees to whom Awards shall be granted and the number of Common Shares or units to be covered by each Award, the Committee shall take into account the nature of the Employee’s duties, the present and potential contributions to the success of the Company, and such other factors as it shall deem relevant in connection with accomplishing the purposes of the Plan.

No award of Incentive Stock Options shall result in the aggregate Fair Market Value of Common Shares with respect to which Incentive Stock Options are exercisable for the first time by any Employee during any calendar year (determined at the time the Incentive Stock Option is granted) exceeding $100,000.

The purchase price of the Common Shares covered by each Option shall be determined by the Committee, but in the case of an Incentive Stock Option shall not be less than 100% of the Fair Market Value (110% in the case of a stockholder owning more than 10% of the combined voting power of all classes of Company stock) of the Common Shares on the date the Option is granted, or if there are no sales on such date, on the next preceding day on which there were sales.

The term of each Incentive Stock Option granted under the Plan shall not be more than 10 years (5 years in the case of a stockholder of the Company owning more than 10% of the combined voting power of all classes of Company stock) from the date of grant, as the

5

Committee shall determine, subject to earlier termination as provided in Sections 11 and 12. The term of each Non-Qualified Stock Option granted under the Plan shall be such period of time as the Committee shall determine, subject to earlier termination as provided in Sections 11 and 12.

(i) Subject to the provisions provided herein, an Option granted under the Plan shall become vested as determined by the Committee. The Committee may, in its discretion, determine as a condition of any Option, that all or a stated percentage of the Option shall become exercisable, in installments or otherwise, only after the completion of a specified service requirement, or the satisfaction or occurrence of other conditions. The Committee may also, in its discretion, accelerate the exercisability of any Option at any time and provide in any Award Agreement that the Option shall become immediately exercisable as to all Common Shares remaining subject to the Option upon a Change in Control.

(ii) Subject to applicable regulatory restrictions, an Option may be exercised at any time or from time to time (further subject, in the case of an Incentive Stock Option, to such restrictions as may be imposed by the Code), as to any or all full shares as to which the Option has become exercisable. Notwithstanding the foregoing provision, no Option may be exercised without the prior consent of the Committee by an Insider until the expiration of six months from the date of the grant of the Option.

(iii) Except as provided in Sections 11, 12 and 13, no Option may be exercised at any time unless the holder thereof is then an Employee, director or individual independent contractor of the Company or one of its Affiliates.

The purchase price of the Common Shares as to which an Option is exercised shall be paid in full at the time of exercise. Payment may be made (i) in cash, which may be paid by check, or other instrument acceptable to the Company, (ii) with the consent of the Committee or the Chief Executive Officer, in Common Shares, valued at the Fair Market Value on the date prior to exercise, or if there were no sales on such date, on the next preceding day on which there were sales, (iii) with the consent of the Committee and subject to such terms and conditions as it may determine, by surrender of outstanding Awards under the Plan, (iv) with the consent of the Committee, the delivery of a promissory note containing such terms as deemed acceptable to the Committee, or (v) any combination of the above. In addition, any amount necessary to satisfy applicable federal, state or local tax requirements shall be paid promptly upon notification of the amount due. The Committee may permit such amount to be paid in Common Shares previously owned by the Employee, or a portion of the Common Shares that otherwise would be distributed to such Employee upon exercise of the Option, or a combination of cash and such Common Shares.

6

Unless the Board determines otherwise, and except as otherwise provided herein, all Options outstanding under the Plan shall accelerate and become immediately exercisable for a period of fifteen days, or such longer or shorter period as the Board may prescribe, (the “notice period”) immediately prior to the scheduled consummation of a Change in Control, provided, however, that any such acceleration and any exercise of options during the notice period shall be (i) conditioned upon the consummation of the Change in Control and (ii) effective only immediately before the consummation of such Change in Control.

Upon consummation of any Change in Control, the Plan and all outstanding but unexercised Options shall terminate. Notwithstanding the foregoing, to the extent provision is made in writing in connection with such Change in Control for the continuation of the Plan and the assumption of Options under the Plan theretofore granted, or for the substitution for such Options of new options covering the stock of a successor company, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kinds of shares or units and exercise prices, then the Plan and Options theretofore granted shall continue in the manner and under the terms so provided, and the acceleration and termination provisions set forth in the first two sentences of this Section 6(e) shall be of no effect. The Company shall send written notice of a Change in Control to all individuals who hold Options not later than the time at which the Company gives notice thereof to its stockholders.

The Committee may award Stock Appreciation Rights to Employees of the Company or any of its Affiliates. Stock Appreciation Rights may be either Tandem Rights or Freestanding Rights. Tandem Rights may be awarded either at the time the Option is granted or at any time prior to the exercise of the Option.

(i) Each Tandem Right shall be subject to the same terms and conditions as the related Option and shall be exercisable only to the extent the Option is exercisable.

(ii) The price per share specified in a Freestanding Right shall be determined by the Committee, but in no event shall be less than the Fair Market Value of the Common Shares as of the date of grant. The term of each Freestanding Right shall be such period of time as the Committee shall determine. Subject to the provisions of the Plan, each Freestanding Right shall become vested as determined by the Committee. Prior to becoming 100% vested, each Freestanding Right shall become exercisable, in installments or otherwise, as the Committee shall determine. The Committee may also, in its discretion, accelerate the exercisability of any Freestanding Right at any time, including a Change in Control.

7

(i) Upon exercise of a Stock Appreciation Right, (subject, in the case of a Tandem Right, to the surrender of the related Option or any unexercised portion thereof which the Employee determines to surrender for this purpose) the Employee shall be entitled to receive, subject to the provisions of the Plan and such rules and regulations as from time to time may be established by the Committee, a payment having an aggregate value equal to (A) the excess of (i) the Fair Market Value on the exercise date of one Common Share over (ii) the Option price per share, in the case of a Tandem Right, or the price per share specified in the terms of a Freestanding Right, times (B) the number of Common Shares with respect to which the Stock Appreciation Right shall have been exercised.

(ii) Upon exercise of a Tandem Right, the number of Common Shares subject to exercise under the related Option shall automatically be reduced by the number of Common Shares represented by the Option or portion thereof surrendered.

(iii) A Tandem Right related to an Incentive Stock Option may only be exercised if the Fair Market Value of a Common Share on the exercise date exceeds the Option price.

(i) The payment described in subparagraph (c)(i) above shall be made in the form of cash, Common Shares, or a combination thereof, as elected by the Employee, provided that the Committee shall have sole discretion to consent to or disapprove the election of an officer or director to receive all or part of a payment in cash.

(ii) If upon exercise of a Stock Appreciation Right the Employee is to receive a portion of the payment in Common Shares, the number of shares received shall be determined by dividing such portion by the Fair Market Value of a share on the exercise date. The number of Common Shares received may not exceed the number of Common Shares covered by any Option or portion thereof surrendered. Cash will be paid in lieu of any fractional share.

(iii) Whether payments to Employees upon exercise of Tandem Rights or Freestanding Rights are made in cash, Common Shares or a combination thereof, the Committee shall have sole discretion as to timing of the payments, whether in one lump sum or in annual installments or otherwise deferred, which deferred payments may in the Committee’s sole discretion (i) bear amounts equivalent to interest or cash dividends, (ii) be treated as invested in the manner from time to time determined by the Committee, with dividends or other income thereon being deemed to have been so reinvested, or (iii) for the convenience of the Company, contributed to a trust, which may be revocable by the Company or subject to the claims of its creditors, for investment in the manner from time to time determined by the Committee and set forth in the instrument creating such trust, all as the Committee shall determine.

8

(iv) No payment will be required from the Employee upon exercise of a Stock Appreciation Right, except that any amount necessary to satisfy applicable federal, state or local tax requirements shall be withheld or paid promptly upon notification of the amount due and prior to or concurrently with delivery of cash or a certificate representing shares. The Committee may permit such amount to be paid in (i) Common Shares previously owned by the Employee, (ii) a portion of the Common Shares that otherwise would be distributed to such Employee upon exercise of the right, or (iii) a combination of cash and Common Shares.

Restricted Stock or Restricted Stock Units may be awarded by the Committee in its sole discretion. At the time an award of Restricted Shares or Restricted Units is made, the Committee shall (i) establish a Restricted Period applicable to such award, (ii) prescribe conditions for the incremental lapse of restrictions during the Restricted Period, or for the lapse or termination of restrictions upon the satisfaction or occurrence of other conditions in addition to or other than the expiration of the Restricted Period, including a Change in Control, and (iii) determine all other terms and conditions of such award, including voting and dividend or dividend equivalent rights.

Upon the grant of Restricted Shares, a stock certificate representing the number of Common Shares equal to the number of Restricted Shares granted to an Employee shall be registered in the Employee’s name but shall be held in custody by the Company for the Employee’s account. The Employee shall not be entitled to delivery of the certificate or to sell, transfer, assign, pledge or otherwise encumber the Restricted Shares until the expiration of the Restricted Period and the satisfaction of any other conditions prescribed by the Committee. Upon the forfeiture of any Restricted Shares, such forfeited Restricted Shares shall be transferred to the Company without further action by the Employee.

Upon the expiration or termination of the Restricted Period and the satisfaction of any other conditions prescribed by the Committee or at such earlier time as provided for in Section 12, a stock certificate for the number of Common Shares with respect to which the restrictions have lapsed, or one Common Share for each Restricted Stock Unit with respect to which the restrictions have lapsed, shall be delivered, free of all such restrictions, except any that may be imposed by law, to the Employee or the Employee’s beneficiary or estate, as the case may be. Fractional Shares will be paid in cash.

9

No payment will be required from the Employee upon the issuance or delivery of any Common Shares, except that any amount necessary to satisfy applicable federal, state or local tax requirements shall be withheld or paid promptly upon notification of the amount due and prior to or concurrently with the issuance or delivery of a certificate representing such shares. The Committee may permit such amount to be paid in (i) Common Shares previously owned by the Employee, (ii) a portion of the Common Shares that otherwise would be distributed to such Employee upon the lapse of the restrictions applicable to the Restricted Shares or Restricted Units, or (iii) a combination of cash and Common Shares.

Performance Awards may be granted to any Employee by the Committee in its sole discretion. A Performance Award shall consist of a right that is (i) denominated in cash or Common Shares, (ii) valued, as determined by the Committee, in accordance with the achievement of such performance goals during such performance periods as the Committee shall establish, and (iii) payable at such time and in such form as the Committee shall determine.

Subject to the terms of the Plan and any applicable Award Agreement, the Committee shall (i) determine the performance goals to be achieved during any performance period, (ii) the length of any performance period, (iii) the amount of any Performance Award, (iv) the amount and kind of any payment or transfer to be made pursuant to any Performance Award, and (v) all other terms and conditions of any Performance Award, including the consequences of death, Total Disability, termination of employment and Change in Control.

Performance Awards may be paid in a lump sum or in installments following the close of the performance period or, in accordance with procedures established by the Committee, on a current or deferred basis.

The Committee shall have authority to grant to eligible Employees an “Other Stock-Based Award,” which shall consist of any right that is an Award of Common Shares or an Award denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Common Shares (including, without limitation, securities convertible into Common Shares), as deemed by the Committee to be consistent with the purposes of the Plan, other than an Award described in Sections 6 through 9 above.

10

Unless otherwise determined by the Committee, and subject to such restrictions as may be imposed by the Code in the case of any Incentive Stock Options, in the event that the employment of an Employee to whom an Option or Stock Appreciation Right has been granted under the Plan shall be terminated (except as set forth in Section 12), such Option or Stock Appreciation Right may, subject to the provisions of the Plan, be exercised, to the extent that the Employee was entitled to do so at the termination of his employment, at any time within three months after such termination, but in no case later than the date on which the Option or Stock Appreciation Right terminates.

Unless otherwise determined by the Committee, if an Employee to whom Restricted Stock or Restricted Stock Units have been granted ceases to be an Employee prior to the end of the Restricted Period and the satisfaction of any other conditions prescribed by the Committee for any reason other than death or Total Disability, the Employee shall immediately forfeit all Restricted Stock and Restricted Stock Units.

Unless otherwise determined by the Committee, if an Employee to whom an Option or Stock Appreciation Right has been granted under the Plan shall die or suffer a Total Disability while employed by the Company, such Option or Stock Appreciation Right may be exercised, to the extent it was exercisable at the date of such Employee’s death or Total Disability, at any time within one year after the date of the Employee’s death or Total Disability, but in no case later than the date on which the Option or Stock Appreciation Right otherwise terminates.

If an Employee to whom Restricted Stock or Restricted Stock Units have been granted shall die or suffer a Total Disability prior to the end of the Restricted Period and the satisfaction of any other conditions prescribed by the Committee, or in cases of other special circumstances, the Committee may, in its sole discretion, waive in whole or in part any or all remaining restrictions with respect to such Employee’s Restricted Stock or Restricted Stock Units.

Awards granted under the Plan shall not be transferable other than by will or the laws of descent and distribution, or pursuant to a qualified domestic relations order as defined by Section 414(p) of the Code except to the extent provided in any Award Agreement and permitted under applicable law.

11

(a) The existence of outstanding Options or other Awards shall not affect in any way the right or ability of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Shares or the rights hereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business or substantially all of the outstanding stock of the Company, or any other corporate act or proceeding, whether of a similar character or otherwise.

(b) If the Company shall effect a subdivision, consolidation or reclassification of the Common Shares or other capital readjustment or recapitalization, the payment of a stock dividend, or other increase or reduction in the number of the Common Shares outstanding, without receiving compensation therefor in money, services or property, then the number, class, and per share price of Common Shares shall be appropriately adjusted in such a manner as to entitle Employees to receive, for the same aggregate cash consideration, if applicable, the same total number and class of shares as he would have received as a result of the event requiring the adjustment and the number of shares of stock which may be issued under the Plan shall be appropriately adjusted in order to prevent dilution or enlargement of rights.

(c) Except as hereinbefore expressly provided, the issue by the Company of shares of stock of any class, for cash or property, or for labor or services, either upon direct sale or 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, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Common Shares then subject to outstanding options.

The Plan was effective as of September 1, 1999; provided that the adoption of the amended and restated Plan shall have been approved by the stockholders of the Company not later than 12 months after the date of such amendment and restatement. The Committee may, in its discretion, grant Awards under the Plan, the grant, exercise or payment of which shall be expressly subject to the conditions that, to the extent required at the time of grant, exercise or payment, (i) if the Company deems it necessary or desirable, a Registration Statement under the Securities Act of 1933, as amended, with respect to such Common Shares shall be effective, and (ii) any requisite approval or consent of any governmental authority of any kind having jurisdiction over Awards granted under the Plan shall be obtained.

(a) The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 14 relating to adjustments upon changes in the Common Shares, no

12

amendment shall be effective unless approved by the stockholders of the Company within twelve (12) months before or after the adoption of the amendment, where the amendment will:

(i) Increase the number of Common Shares reserved for Awards under the Plan;

(ii) Modify the requirements as to eligibility for participation in the Plan (to the extent such modification requires stockholder approval in order for the Plan to satisfy the requirements of Section 422(b) of the Code); or

(iii) Modify the Plan in any other way if such modification requires stockholder approval in order for the Plan to satisfy the requirements of Section 422(b) of the Code.

(b) The Board may in its sole discretion submit any other amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations promulgated thereunder regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation to certain executive officers.

(c) It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide optionees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to employee Incentive Stock Options and/or to bring the Plan and/or Options granted under it into compliance therewith.

(d) Rights and obligations under any Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan, unless: (i) the Company requests the consent of the person to whom the Award was granted; and (ii) such person consents in writing.

(a) The Board may suspend or terminate the Plan at any time. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated. No Incentive Stock Options may be granted under the Plan after August 31, 2009.

(b) Rights and obligations under any Awards granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except with the consent of the Person to whom the Award was granted.

Each Award hereunder shall be evidenced by an Award Agreement that shall contain such restrictions, terms and conditions as the Committee may require.

13

Nothing in the Plan or in any Award granted pursuant to the Plan shall confer upon any Employee any right to continue in the employ of the Company or any of its subsidiaries or interfere in any way with the right of the Company or any such subsidiary to terminate such employment at any time.

The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan and any Award Agreement shall be determined in accordance with the laws of the State of Delaware.

If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Employee or Award, or would disqualify the Plan or any Award under any law or regulations deemed applicable, or the compliance with which is deemed desirable, including any accounting rules or regulations, by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, rules or regulations, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Employee or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

The Committee may refuse to issue or transfer any Common Shares or other consideration under an Award if, acting in its sole discretion, it determines that the issuance or transfer of such Common Shares or such other consideration might violate any applicable law or regulation or entitle the Company to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by an Employee, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Employee, holder, or beneficiary.

14

IN WITNESS WHEREOF, the Company has caused its duly authorized officer to execute this Amended and Restated 1999 Equity Incentive Plan as of this 21^st day of May 2003.
