                                    AGREEMENT

         NOW, THEREFORE, in consideration of the foregoing recitals and other
good and valuable consideration, the receipt and adequacy of which is hereby
acknowledged, and intending to be legally bound, the parties hereto agree as
follows:

1. Definitions. Capitalized terms used but not defined in this Amendment shall
have the meanings given to them in the Loan Agreement.

2. Amendments to Third Amended and Restated Schedule to Loan and Security
Agreement.

         2.1 Section 1 (Credit Limit). The first paragraph of Paragraph 1 of
Section 1 is amended by deleting the existing first paragraph and replacing it
with the following:

                  "1. Accounts Loans. An amount not to exceed (a) the lesser of
                  (i) $3,000,000 at any one time outstanding (the "Maximum
                  Credit Limit"), or (ii) 80% (the "Advance Rate") of the amount
                  of Borrower's Eligible Accounts (as defined in Section 8
                  above); minus (b) the principal amount of all term loans due
                  to Silicon, subject to a maximum of $1,000,000; provided
                  however, that the term debt shall no longer be deducted after
                  Borrower has received equity contributions or Subordinated
                  Debt in the aggregate amount of not less than $2,000,000 from
                  and after August 1, 2006. The term "Subordinated Debt" means
                  indebtedness incurred by Borrower subordinated to all of
                  Borrower's now or hereafter Obligations to Silicon (pursuant
                  to a subordination, intercreditor, or other similar agreement
                  in form and substance satisfactory to Silicon entered into
                  between Silicon and the other creditor), on terms acceptable
                  to Silicon."

         2.2 Section 2 (Interest Rate). The first paragraph of Section 2 is
amended by deleting the existing paragraph and replacing it with the following:

                  "With respect to the Accounts Loans:

                  A rate equal to the following: (i) if the Liquidity Coverage
                  ratio is less than 1.5 to 1.0, then the interest rate is the
                  Prime Rate in effect from time to time, plus 1.50% per annum;
                  and (ii) if the Liquidity Coverage ratio is equal to or
                  greater than 1.5 to 1.0, then the interest rate is the Prime
                  Rate in effect from time to time, plus 1.00% per annum. If any
                  change in the interest rate is due to a change in the
                  Liquidity Coverage ratio, the change shall take effect on the
                  first day of the month following the month for which the
                  Liquidity Coverage Ratio was calculated. Interest shall be
                  calculated on the basis of a 360-day year for the actual

<PAGE>

                  number of days elapsed. "Prime Rate" means the rate announced
                  from time to time by Silicon as its "prime rate;" it is a base
                  rate upon which other rates charged by Silicon are based, and
                  it is not necessarily the best rate available at Silicon. The
                  interest rate applicable to the Obligations shall change on
                  each date there is a change in the Prime Rate."

         2.3 Section 5 (Financial Covenants). The Liquidity Coverage and
Tangible Net Worth covenants are amended by deleting the existing covenants and
replacing them with the following:


         "Liquidity Coverage:       Commencing with the month ending July 31,
                                    2006, through September 30, 2006, Borrower
                                    shall maintain Liquidity Coverage of not
                                    less than 1.0 to 1.0. Commencing with the
                                    month ending October 31, 2006, Borrower
                                    shall maintain Liquidity Coverage of not
                                    less than 1.5 to 1.0.

         Tangible Net Worth:        Through July 31, 2006, Borrower shall
                                    maintain a Tangible Net Worth of not less
                                    than $5,500,000, increasing by 75% of
                                    quarterly positive Net Income from January
                                    1, 2006, effective as of the last month of
                                    each quarter. In no event will the Tangible
                                    Net Worth covenant be reduced due to any net
                                    loss.

                                    Commencing with the month ending August 31,
                                    2006, Borrower shall maintain a Tangible Net
                                    Worth of not less than $4,500,000,
                                    increasing by 75% of quarterly positive Net
                                    Income from August 1, 2006, and 75% of any
                                    Subordinated Debt incurred by Borrower or
                                    equity or capital contributed to Borrower
                                    after August 1, 2006, effective as of the
                                    last month of each quarter. In no event will
                                    the Tangible Net Worth covenant be reduced
                                    due to any net loss."
