                                the Purchase Shares and the Option (as defined

<PAGE>

                                security holders, the "Grantors") will issue to
                                Cypress an option (the "Option") to purchase
                                such securities then held by them for an
                                aggregate purchase price of $5,062,500 (the
                                "Option Exercise Price"). The Option will be
                                exercisable at any time prior to the first
                                anniversary of the closing date for the Stock
                                Purchase (the "Option Term"). The Option
                                Exercise Price will be payable in Cypress Common
                                Stock to the Grantors pro rata based upon the
                                number of shares of Common Stock held by such
                                Grantor. The Cypress Common Stock issued upon
                                exercise of the Option will be valued (i) at the
                                same price per share at which it was sold to the
                                public in Cypress' initial public offering, or
                                (ii) if Cypress has not completed an initial
                                public offering before exercising the Option, at
                                the same price per share at which it was valued
                                in the last bona fide third party sale of
                                Cypress Common Stock. In no event shall the
                                Cypress Common Stock issued upon exercise of the
                                Option be valued at less than $19.00 per share.

                                If, subsequent to the closing of the Stock
                                Purchase, the Company issues additional shares
                                of Common Stock, each holder of such additional
                                shares of Common Stock will issue to Cypress an
                                option to purchase such shares of Common Stock.
                                Such option will be deemed to be part of the
                                Option, and the aggregate Option Exercise Price
                                will be increased, dollar-for-dollar, for each
                                dollar of additional Common Stock issued
                                subsequent to the closing.

                                The Option Exercise Price shall be subject to
                                adjustment prior to the exercise of the Option.
                                For purposes of calculating these adjustments,
                                the base recurring revenues (excluding hardware
                                sales) upon which any growth rates would be
                                measured shall be determined by averaging the
                                recurring revenue (excluding hardware sales) for
                                the three months of October, November and
                                December 1999. All revenue amounts shall be
                                calculated by management and subject to audit by
                                Arthur Andersen, independent public accountants,
                                in accordance with Generally Accepted Accounting
                                Principles consistently applied. The
                                applicability of each adjustment shall be
                                determined independently from each other
                                adjustment.

                                The Option Exercise Price adjustments are as
                                follows:

                                        (i) if, commencing on December 1, 1999,
                                the Company's monthly growth rate for all
                                recurring revenues (excluding

                                hardware sales) exceeds 2.5% per month, then the
                                Option Exercise Price will be increased by the
                                product of (a) six, times (b) the dollar amount
                                by which the Annualized Growth (calculated by
                                annualizing the average growth rate for all
                                recurring revenues (excluding hardware sales)
                                for the month in which the option is exercised
                                and the immediately preceding month) exceeds a
                                2.5% per month growth rate;

                                        (ii) if the Company's monthly growth
                                rate for all recurring revenues (excluding
                                hardware sales) is less than 2.5%, then there
                                shall be a reduction in the Option Exercise
                                Price equal to the product of (a) six, times (b)
                                the dollar amount by which the Annualized Growth
                                (calculated by annualizing the average growth
                                rate for all recurring revenues (excluding
                                hardware sales) for the month in which the
                                option is exercised and the immediately
                                preceding month) falls short of a 2.5% per month
                                growth rate; and

                                        (iii) the Option Exercise Price will be
                                increased by an amount equal to ten cents
                                ($0.10) per square foot of rentable office space
                                (greater than 100,000 rentable square feet with
                                a minimum of ten tenants and in a geographical
                                location acceptable to Cypress) that becomes
                                subject to a binding license agreement,
                                substantially in the same form and substance as
                                the Company's current license agreements, after
                                the closing date of the Stock Purchase.

Stock Conversion:               So long as Cypress has not exercised the Option,
                                at any time prior to the first anniversary of
                                the closing date for the Stock Purchase, Cypress
                                may, in its sole discretion, convert the
                                Purchase Shares into a secured promissory note
                                of the Company in a principal amount of
                                $1,187,500 (the "Note"). The Note will bear
                                interest at the prime rate as reported from time
                                to time by The Wall Street Journal, compounded
                                quarterly. All interest and principal on the
                                Note shall be paid in full on the first
                                anniversary of the date of issuance of the Note.
                                If the shares held by Cypress are converted into
                                the Note, the Option shall automatically expire.

Additional Investment:          The Existing Stockholders and any third-party
                                investors selected by the Existing Stockholders
                                shall invest an additional $1,250,000 in Common
                                Stock of the Company (the "Additional

                                more that $347,284 in principal amount and
                                accrued interest of currently outstanding
                                promissory notes of the Company. The Company
                                agrees not to disclose any information regarding
                                Cypress' initial public offering in connection
                                with the Additional Investment prior to Cypress'
                                initial filing of its registration statement
                                relating to its public offering of common
                                stock.

                                If the Additional Investment is not completed,
                                the number of shares of Company Common Stock
                                purchased by Cypress, along with the number of
                                shares of Cypress Common Stock issued in
                                consideration therefor, shall be reduced
                                proportionately.

                                Subject to the Supermajority Voting Rights
                                described below, prior to the expiration of the
                                Option Term, the Company may issue Common Stock
                                having an aggregate value of no more than
                                $1,750,000 (including the Additional Investment)
                                without the consent of Cypress.

Capitalization; Ranking:        The current capitalization of the Company prior
                                to the Additional Investment is 1,070,000 shares
                                of Common Stock. The Common Stock purchased in
                                the Stock Purchase will rank pari passu with all
                                currently outstanding Common Stock in all
                                respects, including, without limitation, with
                                respect to dividends, liquidation and voting
                                rights.

                                Company shall provide such reasonable access to
                                Cypress' independent public accountants to the
                                Company's books, records and personnel as may be
                                required to complete a review and/or audit (the
                                "Financial Review') of the financial condition
                                of the Company. The Company acknowledges that
                                the Financial Review is necessary in connection
                                with Cypress' proposed initial public offering
                                of shares of Cypress Common Stock. Cypress will
                                have the right to receive unaudited quarterly
                                and year-to-date financial statements and
