        As

Broker. The undersigned does not have, and shall not attempt to exercise, any influence
over how, when or whether to effect purchases of Warrants pursuant to this agreement.

        The
undersigned may notify Broker that all or part of the Maximum Warrant Purchase will be

Designee; provided, however, that the undersigned hereby agrees to make payment of the
purchase price of such purchase in the event that the Designee fails to make such payment.

        The

option of Roth, the certificates for such Warrants shall contain a legend indicating such
restriction on transferability, it being understood that the Warrants purchased will be

     This Amendment to Employment Agreement (this "Amendment") is entered into
as of September 1, 2005, by and between OpBiz, L.L.C. ("Employer"), and Donna
Lehmann ("Employee").

     Whereas, the Employer and Employee are parties to an Employment Agreement
dated September 1, 2004 (the "Agreement");

     Whereas, Employer and Employee wish to make certain amendments to the
Agreement as set forth below;

     Now, therefore, for good and valuable consideration, the Employer and
Employee agree to amend the Agreement as follows:

1.   The parties wish to delete Section 2 of the Agreement in its entirety and
     replace with the following:

     Effective Date; Specified Term. This Agreement shall be effective as of
     Employee's commencement date. Subject to earlier termination as provided
     herein, the term of the Employee's employment hereunder shall commence on
     September 1, 2004 and terminate on the third anniversary thereof (the
     "Specified Term"). If Employee remains employed by Employer following the
     Specified Term, any such employment shall be on an at-will basis, unless
     the parties agree in writing to extend the Specified Term.

2.   The parties wish to delete the third sentence of Section (8)(a) of the
     Agreement in its entirety and replace with the following:

     In recognition of their heightened need for protection from abuse of
     relationships formed or information garnered before and during the

     and agrees for the Specific Term of the Employee's employment hereunder and

     an affiliated company or entity, engaged in gaming or proposes to engage in

3.   The parties wish to delete Section 11 (b) in its entirety and replace with
     ---------------------------------------------------------------------------
     the following:
     --------------

     Termination by Employer without Cause. Employer may terminate Employee "at
     will" at any time upon fifteen (15) days prior written notice, or, in the
     Employer's sole discretion, the equivalent of two weeks of Base Salary in
     lieu of notice. If Employer terminates Employee at will under this
     paragraph, Employee shall have no right to receive any compensation or
     benefit hereunder or otherwise from Employer or any member of the Employer
     Group on and after the effective date of termination of employment other
     than (1) unpaid Base Salary and accrued paid time off earned to the date of
     termination of employment (which shall be paid on Employer's next scheduled
     payroll date), (2) expense reimbursement pursuant to Section 3(d), (3)

     replace with the following:

     Termination by Employee. Employee may terminate Employee's employment
     hereunder upon thirty (30) days' prior written notice to Employer. If
     Employee shall terminate her employment other than for (a) death, (b)
     Disability, (c) failure of Employer to pay Employee's compensation when
     due, or (d) material reductions in Employee's duties and responsibilities
     without her consent, Employee shall have no right to receive any
     compensation or benefit hereunder or otherwise from Employer or any member
     of the Employer Group on and after the effective date of termination of
     employment other than (1) unpaid Base Salary and accrued paid time off
     earned to the date of termination of employment (which shall be paid on

     then payable to Employee (which shall be paid on Employer's next scheduled
     payroll date), (3) business expense reimbursement pursuant to Section 3(d),
     and (4) benefits provided pursuant to Section 3(c), subject to the terms
     and conditions applicable thereto.

5.   Effect. This Amendment shall act to amend the terms as conditions set forth
     in the Agreement as set forth herein and all other terms and conditions of
     the Agreement shall remain in full force and effect. The Agreement, as so
     amended, shall supersede and replace any and all other prior discussions
     and negotiations as well as any and all agreements and arrangements that
     may have been entered into by and between Employee or any predecessor
     thereof, on the one hand, and Employee, on the other hand, prior to the
     date first written above relating to the subject matter hereof. Employee
     acknowledges that all rights under such prior agreements and arrangements
