The Committee shall have the authority to determine the Participants to whom Cash Awards shall be granted, the amount, and the terms or conditions, if any, as additional compensation for the Participant's services to the Company or its Affiliates. A Cash Award may be granted (simultaneously or subsequently) separately or in tandem with another Award and may entitle a Participant to receive a specified amount of cash from the Company upon such other Award becoming taxable to the Participant, which cash amount may be based on a formula relating to the anticipated taxable income associated with such other Award and the payment of the Cash Award. (h) Other Stock-Based Awards. The Committee may also grant to Participants an Other Stock-Based Award, which shall consist of a right which is an Award denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Shares as is deemed by the Committee to be consistent with the purposes of the Plan.

The terms and conditions of substitute Awards granted may vary from the terms and conditions set forth in the Plan, to the extent the Committee, at the time of grant, deems it appropriate to conform, in whole or in part, to the provisions of awards in substitution for which they are granted. (j) General. (i) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for any other Award granted under the Plan or any award granted under any other plan of the Company or any Affiliate. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan of the Company or any Affiliate may be granted either at the same time as or at a different time from the grant of such other Awards or awards.

Subject to the terms of the Plan and of any applicable Award Agreement, payments or transfers to be made by the Company or an Affiliate upon the grant, exercise or payment of an Award may be made in such form or forms as the Committee shall determine, including, without limitation, cash, Shares, other securities, other Awards or other property, or any combination thereof, and may be made in a single payment or transfer, in installments, or on a deferred basis, in each case in accordance with rules and procedures established by the Committee. Such rules and -8-

9 procedures may include, without limitation, provisions for the payment or crediting of reasonable interest on installment or deferred payments. (iii) Limits on Transfer of Awards.

(B) Except as provided in (C) below, no Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution (or, in the case of Restricted Stock, to the Company) and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate. (C) Notwithstanding anything in the Plan to the contrary, to the extent specifically provided by the Committee with respect to a grant, a Nonqualified Stock Option may be transferred to immediate family members or related family trusts, limited partnerships or similar entities or on such terms and conditions as the Committee may establish. (iv) Term of Awards. The term of each Award shall be for such period as may be determined by the Committee; provided, that in no event shall the term of any Award exceed a period of 10 years from the date of its grant. (v) Share Certificates. All certificates for Shares or other securities of the Company or any Affiliate delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Shares or other securities are then listed, and any applicable Federal or state laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. (vi) Consideration for Grants. Awards may be granted for no cash consideration or for such consideration as the Committee determines including, without limitation, such minimal cash consideration as may be required by applicable law. (vii) Delivery of Shares or other Securities and Payment by Participant of Consideration. No Shares or other securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement (including, without limitation, any exercise price, tax payment or tax -9-

10 withholding) is received by the Company. Such payment may be made by such method or methods and in such form or forms as the Committee shall determine, including, without limitation, cash, Shares, other securities, other Awards or other property, withholding of Shares, cashless exercise with simultaneous sale, or any combination thereof; provided that the combined value, as determined by the Committee, of all cash and cash equivalents and the Fair Market Value of any such Shares or other property so tendered to the Company, as of the date of such tender, is at least equal to the full amount required to be paid pursuant to the Plan or the applicable Award Agreement to the Company. SECTION 7. Amendment and Termination. Except to the extent prohibited by applicable law and unless otherwise expressly provided in an Award Agreement or in the Plan: (i) Amendments to the Plan. The Board or the Committee may amend, alter, suspend, discontinue, or terminate the Plan without the consent of any stockholder, Participant, other holder or beneficiary of an Award, or other Person.

The Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4(c) of the Plan) affecting the Company, any Affiliate, or the financial statements of the Company or any Affiliate, 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. SECTION 8. Change in Control. Notwithstanding any other provision of this Plan to the contrary, in the event of a Change in Control of the Company all outstanding Awards automatically shall become fully vested immediately prior to such Change in Control (or such earlier time as set by the Committee), all restrictions, if any, with respect to such Awards shall lapse, and all performance criteria, if any, with respect to such Awards shall be deemed to have been met in full. For purposes of this Plan, a "Change in Control" shall be deemed to occur: -10-

11 (i) if any person, entity or group (as such terms are used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Act"), other than the Company or its subsidiaries or an employee benefit plan of the Company or its subsidiaries, acquires, directly or indirectly, the beneficial ownership (as defined in Section 13(d) of the Act) of any voting security of the Company and immediately after such acquisition such person is, directly or indirectly, the beneficial owner of voting securities representing 20% or more of the total voting power of all of the then outstanding voting securities of the Company entitled to vote generally in the election of directors; (ii) upon the first purchase of the Company's common stock pursuant to a tender or exchange offer (other than a tender or exchange offer made by the Company); (iii) if the stockholders of the Company shall approve a merger, consolidation, recapitalization or reorganization of the Company, or a reverse stock split of outstanding voting securities, or consummation of any such transaction if stockholder approval is not obtained, other than any such transaction which would result in at least 75% of the total voting power represented by the voting securities of the surviving entity outstanding immediately after such transaction being beneficially owned by the holders of all of the outstanding voting securities of the Company immediately prior to the transactions with the voting power of each such continuing holder relative to other such continuing holders not substantially altered in the transaction; (iv) if the stockholders of the Company shall approve a plan of complete liquidation or dissolution of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets; or (v) if, at any time during any period of two consecutive years, individuals who at the beginning of such period constitute the Board cease for any reason to constitute at least a majority thereof, unless the election or nomination for the election by the Company's stockholders of each new director was approved by a vote of at least two-thirds of the directors then still in office who were directors at the beginning of the period. SECTION 9. General Provisions. (a) No Rights to Awards. No Employee, Participant or other Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Employees, Participants, or holders or beneficiaries of Awards. The terms and conditions of Awards need not be the same with respect to each recipient. (b) Withholding. The Company or any Affiliate is authorized to withhold from any Award, from any payment due or transfer made under any Award or under the Plan or from any compensation or other amount owing to a Participant the amount (in cash, Shares, other securities, Shares that would otherwise be issued pursuant to such Award, other Awards or other property) of -11-

12 any applicable taxes payable in respect of an Award, its exercise, the lapse of restrictions thereon, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such taxes. In addition, the Committee may provide, in an Award Agreement, that the Participant may direct the Company to satisfy such Participant's tax obligation through the withholding of Shares otherwise to be acquired upon the exercise or payment of such Award. (c) No Right to Employment. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of the Company or any Affiliate. Further, the Company or an Affiliate may at any time dismiss a Participant from employment, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or in any Award Agreement. (d) Governing Law. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware and applicable Federal law. (e) Severability. 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 Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, 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, Person or Award and the remainder of the Plan and any such Award shall remain in full force and effect. (f) Other Laws. The Committee may refuse to issue or transfer any Shares or other consideration under an Award if, acting in its sole discretion, it determines that the issuance of transfer or such 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 a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary. (g) No Trust or Fund Created. Neither the Plan nor the Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company or any Affiliate. (h) No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be canceled, terminated, or otherwise eliminated. -12-

13 (i) Headings. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof. (j) Parachute Tax Gross-Up. To the extent that the grant, payment, or acceleration of vesting or payment, whether in cash or stock, of any Award made to a Participant under the Plan (a "Benefit") is subject to a golden parachute excise tax under Section 4999(a) of the Code (a "Parachute Tax"), the Company shall pay such person an amount of cash (the "Gross-up Amount") such that the "net" Benefit received by the person under this Plan, after paying all applicable Parachute Taxes (including those on the Gross-up Amount) and any federal or state taxes on the Gross-up Amount, shall be equal to the Benefit that such person would have received if such Parachute Tax had not been applicable. SECTION 10. Effective Date of the Plan. The Plan shall be effective as of the date of its original approval by the Board. SECTION 11. Term of the Plan. No Award shall be granted under the Plan after the 10th anniversary of the original approval date of the Plan. However, unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award granted prior to such termination, and the authority of the Board or the Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights under such Award, shall extend beyond such termination date. -13-
