                  tenant build-out, landlord's tenant design criteria and the

                  "Construction Management Fee") of:

                        Two Hundred Fifty-Two Thousand Dollars ($252,000). This

                  changes to existing stores or trouble shooting. If the Company
                  requests additional store design or construction services not
                  covered in the scope of this Agreement, such services will be
                  billed to the Company monthly at the rate One Hundred
                  Twenty-Five Dollars ($ 125.00) per hour if such services are
                  performed by a senior construction staff member, at the rate
                  of Seventy-Nine Dollars ($79.00) per hour for a construction
                  crew staff member and at the rate of Fifty-Six Dollars
                  ($56.00) per hour if such services are performed by support
                  staff to the construction staff member.

            (c)   The fee paid under paragraph 2(a) and 2(b) above does not
                  cover expenses. In addition, the Company shall pay all
                  out-of-pocket expenses of Hycel, however, travel and other
                  travel related expenses shall be reimbursed at their cost plus
                  overhead at ten percent (10%). Any single out-of-pocket
                  expense item in excess of $750.00 shall be pre-approved by the
                  Company. On a monthly basis, the Company will reimburse the
                  expenses within ten (10) days after receipt of an invoice.

      3.    Term

            The term of this agreement shall commence on January 1, 2004 and
            shall terminate on December 31, 2004. If Hycel's personnel have
            provided construction management or other services prior to the
            termination of this Agreement, the fees and expenses referred to
            above will be due and payable upon the completion of construction,
            as the case may be. Any of the Company's obligations that have
            accrued prior to the termination of this Agreement shall survive the
            termination of this Agreement.

      4.    Assignment

            without the prior written consent of the other party, such consent
            not to be unreasonably withheld; provided, however, if requested by
            Hycel, the Company will consent to the assignment of this Agreement
            to another entity so long as Hycel or Mark H. Zorensky owns at least
            fifty percent (50%) interest in such entity.
