NOW, THEREFORE, in consideration of the premises, mutual covenants and agreements contained herein and in the Merger Agreement, and for the purpose of protecting the interests of Citco in proceeding with the Merger, the parties hereto agree as follows: 1. Option. Subject to the terms and conditions set ------ forth in this Option Agreement, TCB hereby grants to Citco an irrevocable option ("Option") to purchase up to 223,156 shares ("Option Shares") of Common Stock, $1.00 par value, of TCB ("Shares"), being 19.9% of the number of Shares outstanding on the date of this Agreement before such issuance, at a purchase price of $15.50 per Option Share (such price, as adjusted as applicable, the "Purchase Price"). The number of Option Shares that may be received upon the exercise of the Option and the Purchase Price are subject to adjustment and other conditions as follows: (a) If not in Material breach of the Merger Agreement and provided that no preliminary or permanent injunction or other order against delivery of the Option Shares issued by any court of competent jurisdiction shall be in effect, Citco may exercise the Option, in whole or in part, at any time or from time to time following the occurrence of a Purchase Event (as defined below); provided that, except as otherwise provided in this Option Agreement, the Option shall terminate and be of no further force and effect upon the earliest to occur of (i) the Effective Time, (ii) 15 months after the first occurrence of a Purchase Event (or if, at the expiration of such 15 months, after the first occurrence of a Purchase Event, the Option cannot be exercised by reason of any applicable judgement, decree, order, law, or regulation, thirty (30) business days after such impediment to exercise shall have been removed), or (iii) 18 months after the date of this Agreement, although in the event a court or regulatory authority order is in place that would prevent the exercise of the Option, such date shall be extended for the period that such order is in place. Termination of the Option shall not effect any rights under the Merger Agreement which by their terms extend beyond the date of such termination. As used herein, a "Purchase Event" means the termination of this Agreement under any circumstance which would or could entitle Citco to terminate this Agreement pursuant to Sections 10.1 (b), (c), (d)(ii), or (f) of the Merger Agreement; provided, that a Purchase Event shall not occur unless and until TCB shall have entered into a definitive agreement 1 with a third party with respect to an Acquisition Proposal or an Acquisition Proposal shall have been consummated during the 12 months following such termination of this Agreement. (b) In the event Citco wishes to exercise the Option, it shall send written notice to TCB of the date of the closing of the exercise, which shall be not later than 20 business days from the date of the notice; provided, that such closing shall be held only if (i) such purchase would not otherwise violate or cause the violation of any applicable law, rule, or regulation or any restraining order injunction, decree or ruling issued by court or other governmental authority prohibiting the delivery of such Option Shares, and (ii) any prior notification to or approval of any regulatory authority required in connection with such purchase shall have been made or obtained. If the closing cannot be consummated by reason of the restrictions set forth in this paragraph, the closing shall be held within 10 days following the elimination of such restriction. 2. Reserved Shares. TCB hereby represents and warrants --------------- to Citco that it is taking all necessary corporate and other action to authorize and reserve and permit it to issue, and will have reserved issuance at all times from the date of this Option Agreement until the obligation to deliver Shares upon the exercise of the Option terminates, upon exercise of Option, Shares necessary for Citco to exercise the Option, and TCB will take all necessary corporate action to authorize and reserve for issuance all additional Shares or other securities which may be issued pursuant to any change in the capitalization of TCB. The shares to be issued upon due exercise of the Option, including all additional Shares or other securities which may be issuable upon exercise of Option pursuant to any change in capitalization, upon issuance pursuant to this Option Agreement, shall be duly issued, fully paid and non assessable, and shall be delivered free and clear of all liens, including any pre- emptive rights of any shareholder of TCB. In the event of any recapitalization of TCB, appropriate adjustments will be made in the Option Shares. 3. Repurchase. Not withstanding the other provisions ---------- of this Option Agreement, at any time commencing upon the first occurrence of a Repurchase Event (as defined below) and ending 12 months thereafter, TCB (or any successor entity) shall: (a) At the request of Citco, repurchase from Citco the Option (if and to the extent not previously exercised or terminated) at a price equal to the excess, if any, of (x) the Applicable Price (as defined below) as of the Request Date (as defined below) for a Share over (y) the Purchase Price (subject to adjustment for any recapitalizations as described above), multiplied by the number of Shares with respect to which the Option had not been exercised (the "Option Repurchase Price"); and (b) At the request of Citco, from time to time, repurchase, all but not less than all of the Option Shares owned directly or indirectly by Citco at a price equal to the Applicable Price as of the Request Date multiplied by number of Option Shares owned directly or indirectly by Citco (the "Option Share Repurchase Price"). At any time following the occurrence of Purchase Event, TCB (or any successor entity) may at its election, repurchase the Option (if and to the extent not previously exercised or terminated) or all but not less than all of the Option Shares at the Option Repurchase Price or the Option Share Repurchase Price, as the case may be.
