SECTION 3.07                                                                                            Grant of Option.

(a)                                  The Shareholder hereby grants to Parent an irrevocable option (the “Option”) to purchase the Shares with respect to which the Shareholder has the power of disposition, other than those Transferred pursuant to the Permitted Transfers (the “Option Shares”), at a purchase price per share of $6.50 per Share (the “Exercise Price”), in the manner set forth in this Section.

5

(b)                                 At any time prior to the termination of the Option granted hereunder in accordance with the terms of this Agreement, Parent (or its designee) may exercise the Option, in whole but not in part, if, and only if, on or after the date hereof:

(i)                               Parent terminates the Merger Agreement pursuant to Section 7.1(c)(ii) thereof and within one hundred eighty (180) days thereafter the Company enters into a definitive written agreement with a party other than Parent or its affiliates in respect of an Acquisition Transaction or the Board of Directors of the Company recommends in favor of an Acquisition Transaction with a party other than Parent or its affiliates (either, a “Triggering Event”);

(ii)                            Company terminates the Merger Agreement pursuant to Section 7.1(d)(ii) thereof and within one hundred eighty (180) days thereafter a Triggering Event occurs;

(iii)                         if a Takeover Proposal (as defined in the Merger Agreement) is received or publicly disclosed after the date hereof, and thereafter Parent terminates the Merger Agreement pursuant to Section 7.1(c)(i) thereof and within one hundred eighty (180) days thereafter a Triggering Event occurs;

(iv)                        if a Takeover Proposal is received or publicly disclosed after the date hereof, and thereafter Parent terminates the Merger Agreement pursuant to Section 7.1(b)(i) thereof and within one hundred eighty (180) days thereafter a Triggering Event occurs; or

(v)                           if a Takeover Proposal is received or publicly disclosed after the date hereof, and thereafter Parent terminates the Merger Agreement pursuant to Section 7.1(b)(ii) thereof and within one hundred eighty (180) days thereafter a Triggering Event occurs.

In order to exercise the Option, Parent must give written notice (the “Option Notice”, with the date of the Option Notice being hereinafter called the “Notice Date”) to the Shareholder within ten (10) business days after the occurrence of a Triggering Event but during the term of the Option that it will purchase the Option Shares pursuant to the Option.  The Option Notice shall specify a place and date (not earlier than three (3) business days from the Notice Date and not later than twenty (20) business days from the Notice Date) for closing such purchase (a “Closing”).  Parent’s obligation to purchase the Option Shares upon any exercise of the Option, and the Shareholder’s obligation to sell the Option Shares upon any exercise of the Option, is subject (at the election of each of Parent or Shareholder) to the conditions that (i) no preliminary or permanent injunction or other order against the purchase, issuance or delivery of the Option Shares issued by any federal, state or foreign court of competent jurisdiction shall be in effect (and no action or proceeding shall have been commenced or threatened for purposes of obtaining such an injunction or order) and (ii) any applicable waiting period under the HSR Act shall have expired.  The Parent’s obligation to purchase the Option Shares upon any exercise of the Option is further subject (at its election) to the condition that there shall have been no material breach of the representations, warranties, covenants or agreements of the Shareholder contained in this Agreement or of the Company contained in the Merger Agreement.  Notwithstanding the foregoing, any failure by Parent to purchase Option Shares upon the proper exercise of the Option as set forth above at any Closing as a result of the non-satisfaction of any of the foregoing purchase conditions shall not affect or prejudice Parent’s right to purchase such Option Shares upon the subsequent satisfaction of such purchase conditions.  The Shareholder’s

6

obligation to sell its Option Shares upon any exercise of the Option (and such Shareholder’s obligations under Section 1 of this Agreement) is subject (at its election) to the further conditions that there shall have been no material breach of the representations, warranties, covenants or agreements of the Parent, Merger Sub, Merger LLC or FIS contained in this Agreement or contained in the Merger Agreement, which breach has not been cured within thirty days of the receipt of written notice thereof from the Shareholder.

At any Closing, (i) Shareholder will deliver to Parent the certificate or certificates representing the Option Shares in proper form for transfer upon exercise of the Option in the denominations designated by Parent in the Option Notice, and (ii) Parent shall pay the aggregate purchase price for the Option Shares to be purchased by wire transfer of immediately available funds to an account, which account shall be designated in writing to Parent within two business days after receipt of the Option Notice in the amount of the Exercise Price times the number of Option Shares to be purchased.

(c)                                  The Shareholder has granted the Option to the Parent in order to induce Parent to enter into and consummate the transactions contemplated by the Merger Agreement.

SECTION 3.08                                                                                            Stock Option Exercise.  The Shareholder agrees that prior to the Effective Time he shall Transfer all shares of the Option Common Stock acquired after     January 6, 2004, except for shares of Option Common Stock acquired pursuant to the exercise of any stock option or derivative security that would otherwise expire prior to the Effective Time.

SECTION 3.09                                                                                            Increase of Outstanding Indebtedness.  The Shareholder agrees that he shall not increase the amount outstanding under the Outstanding Indebtedness (other than interest and fees that may accrue by its terms) during the term of this Agreement.
