Exhibit 10.2.3 OPTION GRANT CERTIFICATE ENHANCE FINANCIAL SERVICES GROUP INC., a New York corporation (the "Company"), hereby grants to _________________ (the "Executive") an Incentive Stock Option (the "Option") to purchase _____ shares (the "Option Shares") of common stock, par value $.10 per share ("Common Stock"), pursuant to the Company's 1997 Long-Term Incentive Plan for Key Employees (as such may be amended from time to time, the "Plan"). 1. BASIC TERMS OF OPTION. (A) TERM OF OPTION. The option shall expire December 31, 2009. (b) EXERCISE PRICE. The exercise price shall be $16.4375 per Option Share (the "Purchase Price"). (c) VESTING. The Option shall become exercisable in equal installments in accordance with Article 3. (d) METHOD OF EXERCISE. The Option may be exercised by the Executive in accordance with the terms hereof and of the Plan for any and all Option Shares by written notice (the "Exercise Notice") from the Executive to the Company or its designee in such form as the Company shall prescribe. Payment of the Purchase Price may be made in the form of cash or shares of Common Stock, as permitted by the Plan, and shall accompany the Exercise Notice to the Company; provided that, if such Exercise Notice indicates that the Executive is simultaneously using the stock option exercise program of a financial services provider or other brokerage concern approved by the Company, the Purchase Price shall be payable on the fifth business day following the date of delivery of the Exercise Notice. 2. OPTION SHARES. (a) STATUS OF OPTION SHARES. Effective upon the exercise of the Option in whole or in part and the receipt by the Company of the Purchase Price for the Option Shares being purchased, the Executive shall be the holder of record of such shares and shall have all of the rights of a shareholder with respect thereto (including the right to vote such shares at any meeting at which the holders of the Common Stock may vote, the right to receive all dividends declared and paid upon such shares and the right to exercise any rights or warrants issued in respect of any such shares). The Company shall, upon receipt of the Purchase Price, issue in the name of the Executive a certificate representing the Option Shares purchased from time to time. (b) OPTION SHARES UNREGISTERED. As of the date of grant of the Option, the Option Shares have been registered under the Securities Act of 1933, as amended (the "Act"). However, the Company has no obligation to maintain the effectiveness of the registration of the Option Shares under the Act. Unless the Option Shares issuable upon a given exercise are then subject to an effective registration statement under the Act, the certificate representing such shares shall bear the following legend or such other legend as the Company's counsel may deem appropriate: "The shares represented by this certificate have not been registered under the Securities Act of 1933, as amended, and may in no event be offered, sold, transferred or assigned unless and until the shares have been so registered or, in the opinion of counsel to Enhance Financial Services Group Inc., an exemption from such registration is available." (c) INVESTMENT INTENT. If the certificate representing the Option Shares issuable upon a given exercise is required to bear the legend set forth above (or a legend to like effect), the Executive shall, by such exercise of the Option, be deemed conclusively to represent and to agree with the Company that he or she is acquiring the Option Shares then being purchased for his or her own account and not for the account of others, for investment only and not with a view to public sale or distribution. (d) RESTRICTION RELATING TO CERTAIN MERGERS. In the event of a merger or consolidation of the Company with a third party which is proposed to be accounted for as a pooling of interests, the Executive shall, if so requested by the Company and notwithstanding any other provision of this Certificate, agree not to sell, assign, or gift or in any other way reduce his or her risk relative to the Option Shares and all other shares of Common Stock owned by the Executive for such period after the consummation of such merger or consolidation as the Company shall, upon the advice of its outside accountants, conclusively determine as necessary to ensure that such merger or consolidation may be validly accounted for as a pooling of interests. (e)PRIOR CONDITIONS. The Company shall not be required to issue or deliver any certificate representing Option Shares prior to (i) the admission of such shares to listing on any stock exchange on which the Common Stock may then be listed, (ii) the completion of any registration or any other qualification of such shares under any federal or state law or any rulings or regulations of any governmental regulatory body, (iii) the obtaining of any consent or approval or other clearance from any governmental agency which the Company shall, in its sole discretion, determine to be necessary or advisable, and (iv) the payment to the Company, upon its request, of any amount requested by the Company for the purposes of satisfying its liability, if any, to withhold taxes of any kind or any other applicable assessment (plus interest or penalties thereon, if any, caused by a delay in making such payment) incurred by reason of the exercise of the Option. 2 3.

Should the Executive's employment be terminated before any given date set forth in Paragraph 3(a) upon his or her death, Disability or Retirement, then the installments of the Option which are vested at the time of such termination shall remain exercisable in accordance with the terms hereof as if such termination of employment shall not have occurred. Should the Executive's employment be terminated by the Company or a Subisidiary other than for Cause, the vested portion of the Option not subsequently exercised on or before the 90th day after such termination shall thereupon automatically terminate. Should the Executive's employment be terminated under any other circumstances, the vested portion of the Option shall thereupon automatically terminate. (c) EFFECT OF LEAVE OF ABSENCE.
