FOR VALUE RECEIVED, DATREK MILLER INTERNATIONAL, INC. , a Florida corporation (the “ Company ” ), hereby certifies that Stanford International Bank Ltd. (the “ Holder ” ) is entitled, subject to the provisions of this Warrant, to purchase from the Company up to Six Hundred Thousand (600,000) shares of common stock (the “ Common Shares ” ), par value $0.001 per share ( “ Common Stock ” ), of the Company at an exercise price per Common Share equal to the par value now or hereafter per Common Share as the same may be changed as a result of a reverse split, a split or reclassification (the “ Exercise Price ” ), during the period commencing July 18, 2005 and expiring at 5:00 P.M., Eastern Standard time, on July 17, 2010 (5 years from the date of issuance).

The number of Common Shares to be received upon the exercise of this Warrant may be adjusted from time to time as hereinafter set forth. The Common Shares deliverable upon such exercise, or the entitlement thereto upon such exercise, and as adjusted from time to time, are hereinafter sometimes referred to as “ Warrant Stock .” The Warrants issued on the same date hereof bearing the same terms and conditions as this Warrant shall be collectively referred to as the “ Warrants ” .

The Holder agrees with the Company that this Warrant is issued, and all the rights hereunder shall be held subject to, all of the conditions, limitations and provisions set forth herein.

1. EXERCISE OF WARRANT. This Warrant may be exercised by its presentation and surrender to the Company at its principal office (or such office or agency of the Company as it may designate in writing to the Holder hereof), commencing on July 18, 2005

( “ Date of Issuance ” ) and expiring at 5:00 P.M., Eastern Standard time, on July 17, 2010 (5 years from the Date of Issuance), with the Warrant Exercise Form attached hereto duly executed and accompanied by payment (either in cash or by certified or official bank check or by wire transfer, payable to the order of the Company) of the Exercise Price for the number of shares specified in such Form.

The Company agrees that the Holder hereof shall be deemed the record owner of such Common Shares as of the close of business on the date on which this Warrant shall have been presented and payment made for such Common Shares as aforesaid whether or not the Company or its transfer agent is open for business. Certificates for the Common Shares so purchased shall be delivered to the Holder hereof within a reasonable time, not exceeding 15 days, after the rights represented by this Warrant shall have been so exercised. If this Warrant should be exercised in part only, the Company shall, upon surrender of this Warrant for cancellation, execute and deliver a new Warrant evidencing the rights of the Holder hereof to purchase the balance of the shares purchasable hereunder as soon as reasonably possible.

2. COVENANTS BY THE COMPANY

The Company covenants and agrees as follows:

(a) Reservation of Shares. During the period within which the rights represented by this Warrant may be exercised, the Company shall, at all times, reserve and keep available out of its authorized capital stock, solely for the purposes of issuance upon exercise of this Warrant, such number of its Common Shares as shall be issuable upon the exercise of this Warrant. If at any time the number of authorized Common Shares shall not be sufficient to effect the exercise of this Warrant, the Company will take such corporate action as may be necessary to increase its authorized but unissued Common Shares to such number of shares as shall be sufficient for such purpose. The Company shall have analogous obligations with respect to any other securities or property issuable upon exercise of this Warrant.

(b) Valid Issuance, etc. All Common Shares which may be issued upon exercise of the rights represented by this Warrant included herein will be, upon payment thereof, validly issued, fully paid, non-assessable and free from all taxes, liens and charges with respect to the issuance thereof.

(c) Taxes. All original issue taxes payable in respect of the issuance of Common Shares upon the exercise of the rights represented by this Warrant shall be borne by the Company, but in no event shall the Company be responsible or liable for income taxes or transfer taxes upon the issuance or transfer of this Warrant or the Warrant Stock.

(d) Fractional Shares. The Company shall not be required to issue certificates representing fractions of Common Shares. In lieu of any fractional interests, the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction.

3. EXCHANGE OR ASSIGNMENT OF WARRANT

This Warrant is exchangeable, without expense, at the option of the Holder, upon presentation and surrender hereof to the Company for other Warrants of different denominations,

entitling the Holder to purchase in the aggregate the same number of Common Shares purchasable hereunder. Subject to the provisions of this Warrant and the receipt by the Company of any required representations and agreements, upon surrender of this Warrant to the Company with the Warrant Assignment Form annexed hereto duly executed and funds sufficient to pay any transfer tax, the Company shall, without additional charge, execute and deliver a new Warrant in the name of the assignee named in such instrument of assignment and this Warrant shall promptly be canceled. In the event of a partial assignment of this Warrant, the new Warrants issued to the assignee and the Holder shall make reference to the aggregate number of shares of Warrant Stock issuable upon exercise of this Warrant.

4. RIGHTS OF THE HOLDER

The Holder shall not, by virtue hereof, be entitled to any voting or other rights of a stockholder of the Company, either at law or in equity, and the rights of the Holder are limited to those expressed in this Warrant.

5. ADJUSTMENT OF EXERCISE PRICE

(a) Common Stock Dividends; Common Stock Splits; Reclassification. If the Company, at any time while this Warrant is outstanding, (a) shall pay a stock dividend on its Common Stock, (b) subdivide outstanding shares of Common Stock into a larger number of shares (or combine the outstanding shares of Common Stock into a smaller number of shares) or (c) issue by reclassification of shares of Common Stock any shares of capital stock of the Company, then (i) the Exercise Price shall be multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding after such event and (ii) the number of shares of the Warrant Stock shall be multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately after such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such event. Any adjustment made pursuant to this Section 5.1 shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution or, in the case of a subdivision or re-classification, shall become effective immediately after the effective date thereof.

Such adjustment shall be made whenever such rights, options, warrants or other securities are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights, options, warrants or other securities.

(c) Subscription Rights. If the Company, at any time while this Warrant is outstanding, shall fix a record date for the distribution to holders of its Common Stock, evidence of its indebtedness or assets or rights, options, warrants or other security entitling them to subscribe for or purchase, convert to, exchange for or otherwise acquire any security (excluding those referred to in Sections 5(a) and 5(b) above), then in each s
