            "1. CREDIT LIMIT
                (Section 1.1):      An amount equal to the sum of 1 and 2 below:

                                    1. Revolving Loans. An amount not to exceed
                                    the lesser of: (i) $2,000,000 at any one
                                    time outstanding (the "Maximum Credit
                                    Limit") or (ii) 65% of the amount of the
                                    Eligible Receivables (as defined in Section
                                    8 above) of Rixon Networks, Inc. only.

                     Loans, if any, will be made to each Borrower based on the
                     Eligible Receivables of each Borrower, subject to the
                     Maximum Credit Limit set forth above for all Loans to all
                     Borrowers combined. Notwithstanding the foregoing, Borrower
                     agrees and understands that, absent further written
                     amendment hereto, Loans, if any, at this time will only be
                     made to Rixon Networks, Inc. based on the Eligible
                     Receivables of Rixon Networks, Inc.

                                    plus

                                    2. Cash Secured Letter of Credit No. 1.
                                    $300,000. Silicon previously issued for the
                                    account of Borrower a Standby Letter of
                                    Credit in the amount of $300,000 (the
                                    "Standby Letter of Credit No. 1"), which
                                    Standby Letter of Credit is secured by a
                                    certificate of deposit pledged to Silicon on
                                    Silicon's standard form documentation."

         2. Modified Minimum Monthly Interest. The Minimum Monthly Interest set
forth in that portion of the Schedule to Loan and Security Agreement entitled
"2. INTEREST." is hereby amended to read as follows:

            "Minimum Monthly
            Interest (Section 2.1): $3,000."

Security Agreement is hereby amended to read as follows:

         4. Modified Tangible Net Worth Financial Covenant. The Minimum Tangible
Net Worth Financial Covenant set forth in that portion of the Schedule to Loan
and Security Agreement entitled "5. FINANCIAL COVENANTS (Section 5.1)" is hereby
amended to read as follows:

            "Minimum Tangible
            Net Worth:              For each month ending after the date hereof,
                                    Borrower shall, on a consolidated basis,
                                    maintain a Tangible Net Worth of not less
                                    than $3,750,000 plus 50% of the Borrower's
                                    net income in each fiscal quarter ending
                                    after the date hereof. Increases in the
                                    Minimum Tangible Net Worth Covenant based on
                                    net income shall be effective on the last
                                    day of the fiscal quarter in which said net
                                    income is realized, and shall continue
                                    effective thereafter. In no event shall the
                                    Minimum Tangible Net Worth Covenant be
                                    decreased."

         5. Deposit Requirement. Borrower covenants and agrees that it shall at
all times maintain its primary banking relationship with Silicon. Without
limiting the generality of the foregoing, Borrower shall, at all times, maintain
not less than 85% of its total cash and investments on deposit with Silicon.

         6. Modification Regarding Interest Computation. The first sentence of
Section 9.1 of the Loan Agreement which currently reads as follows:

            "In computing interest on the Obligations, all checks, wire
            transfers and other items of payment received by Silicon (including
            proceeds of Receivables and payment of the Obligations in full)
            shall be deemed applied by Silicon on account of the Obligations two
            Business Days after receipt by Silicon of immediately available
            funds, and, for purposes of the foregoing, any such funds received
            after 12:00 Noon on any day shall be deemed received on the next
            Business Day."

is hereby amended to read as follows:

            "In computing interest on the Obligations, all checks, wire
            transfers and other items of payment received by Silicon (including
            proceeds of Receivables and payment of the Obligations in full)
            shall be deemed applied by Silicon on account of the Obligations
            three Business Days after receipt by Silicon of immediately
            available funds, and, for purposes of the foregoing, any such funds
            received after 12:00 Noon on any day shall be deemed received on the
            next Business Day."

         7. Fee. In consideration for Silicon entering into this Amendment,
Borrower shall concurrently pay Silicon a fee in the amount of $20,000.00, which
shall be non-refundable and in addition to all interest and other fees payable
to Silicon under the Loan Documents. Silicon is authorized to charge said fee to
Borrower's loan account.

         8. Representations True. Borrower represents and warrants to Silicon
that all representations and warranties set forth in the Loan Agreement, as
amended hereby, are true and correct.

         9. General Provisions. This Amendment, the Loan Agreement, any prior
written amendments to the Loan Agreement signed by Silicon and Borrower, and the
other written documents and agreements between Silicon and Borrower set forth in
full all of the representations and agreements of the parties with respect to
the subject matter hereof and supersede all prior discussions, representations,
agreements and understandings between the parties with respect to the subject
hereof. Except as herein expressly amended, all of the terms and provisions of
the Loan Agreement, and all other documents and agreements between Silicon and
Borrower shall continue in full force and effect and the same are hereby
ratified and confirmed.
