(c) Dividend Equivalents. In the sole and complete discretion of the Committee, a Unit Award may provide the Participant with dividend equivalents payable in cash on a current or deferred basis. SECTION 6 (a) Stock Incentive Units. Subject to the provisions of the Plan, the Committee shall have sole and complete authority to determine the Employees to whom Units shall be granted, the number of Units to be granted to an Employee, the exercise price thereof and the conditions and limitations applicable to the exercise thereof. Units shall not be exercisable after the expiration of 10 years after the date of grant. Except in the case of a Unit granted in assumption of or substitution for an outstanding award of a company acquired by the Company or with which the Company combines, the exercise price of any Unit granted under this Plan shall not be less than 100% of the fair market value of a Share on the date of grant. (b) A Unit shall entitle the holder thereof to receive an amount in cash equal to the excess, if any, of the fair market value of a Share on the date of exercise of the Unit over the exercise price. In the event that the Unit is exercised during a period beginning not earlier than one day after the expiration date of an Offer and ending not more than ninety days after the expiration date of such Offer, a Unit shall entitle the holder thereof to receive upon exercise the higher of the amount described in the first sentence of this Section 6(b) and an amount in cash equal to the excess, if any, of the Offer Price on the date of exercise of the Unit over the exercise price. SECTION 7 (a) Amendments to the Plan. The Board may amend, suspend or terminate the Plan or any portion thereof at any time, provided that no amendment shall be made without stockholder approval if such approval is necessary to comply with any tax or regulatory requirement. Notwithstanding anything to the contrary contained herein, the Committee may amend the Plan in such manner as may be necessary for the Plan to conform with local rules and regulations in any jurisdiction outside the United States. (b) Amendments to Unit Award Agreements. The Committee may amend, modify or terminate any outstanding Unit Award Agreement with the holder's consent at any time prior to payment or exercise in any manner not inconsistent with the terms of the Plan, including without limitation, (i) to change the date or dates as of which a Unit Award becomes exercisable, or (ii) to cancel a Unit Award and grant a new Unit Award in substitution therefor under such different terms and conditions as it determines in its sole and complete discretion to be appropriate. (c) Adjustment of Unit Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Unit Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 5(b) hereof) affecting the Company, or the financial statements of the Company or any Subsidiary, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. (d) Cancellation. Any provision of this Plan or any Unit Award Agreement to the contrary notwithstanding, the Committee may cause any Unit Award granted hereunder to be cancelled in consideration of a cash payment made to the holder of such cancelled Unit Award equal in value to such cancelled Unit Award. The determinations of value under this subparagraph shall be made by the Committee in its sole discretion. SECTION 8 (a) Delegation. Subject to the terms of the Plan and applicable law, the Committee may delegate to the Chairman of the Board of the Company the authority, subject to such terms and limitations as the Committee shall determine, to grant Unit Awards to, or to cancel, modify or waive rights with respect to, or to alter, discontinue, suspend, or terminate Unit Awards held by, Employees who are not officers or directors of the Company for purposes of Section 16 of the Exchange Act, or any successor section thereto, or who are otherwise not subject to such Section. (b) Unit Award Agreements. Each Unit Award hereunder shall be evidenced by a writing delivered to the Participant that shall specify the terms and conditions thereof and any rules applicable thereto, including but not limited to the effect on such Unit Award of the death, retirement or other termination of employment of the Participant and the effect thereon, if any, of a change in control of the Company. (c) Withholding. The Company shall deduct from all amounts paid to a Participant (whether under the Plan or otherwise) any taxes required by law to be withheld in respect of Unit Awards hereunder to such Participant. The Committee may provide for additional cash payments to holders of Unit Awards to defray or offset any tax arising from the grant, vesting, exercise or payment of any Unit Award. (d) Transferability. No Unit Award shall be transferable by a Participant other than (i) by will, (ii) by the laws of descent and distribution, or (iii) pursuant to a domestic relations order, as defined in the Code, if permitted by the Committee and so provided in the Unit Award Agreement or an amendment thereto. The designation of a Designated Beneficiary shall not be a violation of this Section 8(d). (e) No Limit on Other Compensation Arrangements. Nothing contained in the Plan shall prevent the Company from adopting or continuing in effect other compensation arrangements, which may, but need not, provide for the grant of the type of awards provided for hereunder (subject to stockholder approval of any such arrangement if approval is required), and such arrangements may be either generally applicable or applicable only in specific cases. (f) No Right to Employment. The grant of a Unit Award shall not be construed as giving a Participant the right to be retained in the employ of the Company or any Subsidiary. The Company or any Subsidiary 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 Unit Award Agreement. No Employee, Participant or other person shall have any claim to be granted any Unit Award, and there is no obligation for uniformity of treatment of Employees, Participants or holders or beneficiaries of Unit Awards. (g) Governing Law. The validity, construction, and effect of the Plan, any rules and regulations relating to the Plan and any Unit Award or Unit Award Agreement shall be determined in accordance with the laws of the State of Delaware. (h) Severability. If any provision of the Plan or any Unit Award Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Unit Award, or would disqualify the Plan or any Unit Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to 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 Unit Award Agreement, such provision shall be stricken as to such jurisdiction, Person or Unit Award and the remainder of the Plan and any such Unit Award Agreement shall remain in full force and effect. (i) No Trust or Fund Created. Neither the Plan nor any Unit Award or Unit Award Agreement shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company pursuant to a Unit Award, such right shall be no greater than the right of any unsecured general creditor of the Company. (j) Headings. Headings are given to the 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. SECTION 9 Effective Date of the Plan. The Plan shall be effective as of the date of its approval by the Board. As amended effective February 4, 1997
