ARTICLE IV

EXERCISE OF OPTION

Section 4.1 Persons Eligible to Exercise

          During the lifetime of the Optionee, only the Optionee, or any person to whom the Option may be transferred pursuant to Section 6.2 below, may exercise the Option or any portion thereof. After the death of the Optionee, any exercisable portion of the Option may, prior to the time when the Option becomes unexercisable under Section 3.3, be exercised by his personal representative or by any person empowered to do so under the deceased Optionee’s will or under the then applicable laws of descent and distribution.

Section 4.2 Partial Exercise

          Any exercisable portion of the Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time when the Option or portion thereof becomes unexercisable under Section 3.3; provided, however, that each partial exercise shall be for not less than one hundred (100) shares of Common Stock and shall be for whole shares only.

Section 4.3 Manner of Exercise

          The Option, or any exercisable portion thereof, may be exercised solely by delivery to the Stock Option Administrator or an agent of the Stock Option Administrator, as designated by the Committee from time to time, of all of the following prior to the time when the Option or such portion becomes unexercisable under Section 3.3:

          (a) A written notice complying with the applicable rules established by the Committee stating that the Option, or a portion thereof, is exercised. The notice shall be signed by the Optionee or other person then entitled to exercise the Option or such portion. It shall be accompanied by payment in cash equal to the product of the per share exercise price times the number of shares of Common Stock with respect to which the option or portion is being exercised;

          (b) A bona fide written representation and agreement, in a form satisfactory to the Committee, signed by the Optionee or other person then entitled to exercise such Option or portion, stating that the shares of Common Stock are being acquired for his own account, for investment and without any present intention of distributing or reselling said shares or any of them except as may be permitted under the Securities Act and then applicable rules and regulations thereunder, and that the Optionee or other person then entitled to exercise such Option or portion will indemnify Catalyst against and hold it free and harmless from any loss, damage, expense or liability resulting to Catalyst if any sale or distribution of the shares of Common Stock by such person is contrary to the representation and agreement referred to above. The Committee may, in its absolute discretion, take whatever additional actions it deems appropriate to insure the observance and performance of such representation and agreement and to effect compliance with the Securities Act and any other federal or state securities laws or regulations. Without limiting the generality of the foregoing, the Committee may require an opinion of counsel acceptable to it to the effect that any subsequent transfer of shares of Common Stock acquired on an Option exercise does not violate the Securities Act, and may issue stop-transfer orders covering such shares. Share certificates evidencing stock issued on exercise of this Option shall bear an appropriate legend referring to the provisions of this subsection (b) and the agreements herein. The written representation and agreement referred to in the first sentence of this subsection (c) shall, however, not be required if the shares of Common Stock to be issued pursuant to such exercise have been registered under the Securities Act, and such registration is then effective in respect of such shares; and

          (c) Full payment to Catalyst of all amounts which, under federal, state or local tax law, it is required to withhold upon exercise of the Option; and

          (d) In the event the Option or any portion thereof shall be exercised pursuant to Section 4.1 by any person or persons other than the Optionee, appropriate proof of the right of such person or persons to exercise the Option.

Section 4.4 Conditions to Issuance of Stock Certificates

          The shares of Common Stock deliverable upon the exercise of the Option, or any portion thereof, may be either previously authorized but unissued shares or issued shares which have then been reacquired by Catalyst. Such shares of Common Stock shall be fully paid and nonassessable. Catalyst shall not be required to issue or deliver any certificate or certificates for shares of stock purchased upon the exercise of the Option or portion thereof prior to fulfillment of all of the following conditions:

          (a) The admission of such shares of Common Stock to listing on all stock exchanges on which such class of stock is then listed; and

          (b) The completion of any registration or other qualification of such shares of Common Stock under any state or federal law or under rulings or regulations of the Securities and Exchange Commission or of any other governmental regulatory body, which the Committee shall, in its absolute discretion, deem necessary or advisable; and

          (c) The obtaining of any approval or other clearance from any state or federal governmental agency which the Committee shall, in its absolute discretion, determine to be necessary or advisable; and

          (d) The receipt by Catalyst of full payment for such shares of Common Stock, including payment of all amounts which, under federal, state or local tax law, Catalyst (or other employer corporation) is required to withhold upon exercise of the Option; and

          (e) The lapse of such reasonable period of time following the exercise of the Option as the Committee may from time to time establish for reasons of administrative convenience.

Section 4.5 Rights as Shareholder

          The holder of the Option shall not be, nor have any of the rights or privileges of, a shareholder of Catalyst in respect of any shares of Common Stock purchasable upon the exercise of any part of the Option unless and until certificates representing such shares of Common Stock shall have been issued by Catalyst to such holder.

ARTICLE V

EFFECT OF CHANGES IN CAPITALIZATION

Section 5.1 Recapitalization

          If the outstanding shares of Common Stock of Catalyst are increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of Catalyst by reason of any recapitalization, reclassification, reorganization (other than as described in Section 5.2 below), stock split, reverse split, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock of Catalyst, or other increase or decrease in such shares effected without receipt of consideration by Catalyst, an appropriate and proportionate adjustment shall be made by the Committee in the number and kind of shares of Common Stock issuable upon exercise of this Option, and in the purchase price per share of this Option.

Section 5.2 Reorganization or Change in Control

          In the event of a Reorganization (as defined below) of Catalyst, this Option shall become immediately vested and, to the extent applicable, exercisable for such period of time specified in Section 3.3(a). For purposes of this Agreement a “Reorganization” of an entity shall be deemed to occur if such entity is a party to a merger, consolidation, reorganization, or other business combination with one or more entities in which said entity is not the surviving entity, if such entity disposes of substantially all of its assets, or if such entity is a party to a spin-off, split-off, split-up or similar transaction; provided, however, that the transaction shall not be a Reorganization if Catalyst, any parent or any subsidiary is the surviving entity.

Section 5.3 Dissolution or Liquidation

          Upon the dissolution or liquidation of Catalyst, this Option shall terminate. In the event of any termination of this Option under this Section 5.3, Optionee shall have the right, immediately prior to the occurrence of such termination and during such reasonable period as the Committee in its sole discretion shall determine and designate, to exercise this Option in whole or in part, whether or not this Option was otherwise exercisable at the time such termination occurs and without regard to any limitation on exercise imposed pursuant to Article III above.

Section 5.4 Adjustments

          Adjustments under this Article V related to stock or securities of Catalyst shall be made by the Committee, whose determination in that respect shall be final, binding, and conclusive. No fractional shares of Common Stock or units of other securities shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole share or unit.

Section 5.5 No Limitations

          The grant of this Option hereunder shall not affect or limit in any way the right or power of Catalyst to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge, consolidate, dissolve or liquidate, or to sell or transfer all or any part of its business or assets.

ARTICLE VI

OTHER PROVISIONS

Section 6.1 Administration

          All actions taken and all interpretations and determinations made by the Committee in good faith shall be final and binding upon the Optionee, Catalyst and all other interested persons. No member of the Committee shall be personally liable for any action, determination or interpretation made in good faith with respect to the Option. In its absolute discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Committee under the Plan and this Agreement except with respect to matters which under Rule 16b-3 or Section 162(m) of the Code, or any regulations or rules issued thereunder, are required to be determined in the sole discretion of the Committee.

Section 6.2 Option Not Transferable

          This Option shall not be assignable or transferable by the Optionee, other than by will or the laws of descent and distribution; provided, however, that this Option may be transferred or assigned to (i) family members or entities (including trusts) established for the benefit of the Optionee or the Optionee’s family members or (ii) any other person, as permitted by applicable securities law. Any Option assigned or transferred pursuant to this Section 6.2 shall continue to be subject to the same terms and conditions as were applicable to the Option immediately before the transfer; provided, however, that any Option transferred for value may not be exercised under any Registration Statement on Form S-8 and upon exercise of such transferred Option the holder will only be entitled to receive shares of restricted stock that have not been registered under the Securities Act.

Section 6.3 Shares to Be Reserved

          Catalyst shall at all times during the term of the Option reserve and keep available such number of shares of Common Stock as will be sufficient to satisfy the requirements of this Agreement.

Section 6.4 Notices

given beneath his signature hereto. By a notice given pursuant to this Section 6.4, either party may hereafter designate a different address for notices to be given to him. Any notice which is required to be given to the Optionee shall, if the Optionee is then deceased, be given to the Optionee’s personal representative if such representative has previously informed Catalyst of his status and address by written notice under this Section 6.4. Any notice shall be deemed duly given when enclosed in a properly sealed envelope or wrapper addressed as aforesaid, deposited (with postage prepaid) in a post office or branch post office regularly maintained by the United States Postal Service; provided, however, that any notice to be given by the Optionee relating to the exercise of the Option or any portion thereof shall be deemed duly given upon receipt by the Stock Option Administrator or his office.

Section 6.5 Titles

          Titles are provided herein for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

Section 6.6 Construction

          This Agreement shall be administered, interpreted and enforced under the internal laws of the State of Florida without regard to conflicts of laws thereof.

Section 6.7 Conformity to Securities Laws

          The Optionee acknowledges that this Agreement is intended to conform to the extent necessary with all provisions of the Securities Act and the Exchange Act and any and all regulations and rules promulgated by the Securities and Exchange Commission thereunder, including, without limitation, the applicable exemptive conditions of Rule 16b-3. Notwithstanding anything herein to the contrary, the Option is granted and may be exercised, only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by applicable law, this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.
