         Cutover Date:

         Mutual Understanding:

         Cutover Date is defined as the date at which Rainmaker will start to
         collect and receive credit for any sales made to customers within the
         [ ] target market. The cutover date will be the go-live date,
         (September 21st). [ ]. If Nortel has booked the contract prior to
         go-live, Nortel will receive credit for the sale. *See section 7. 5 `PO
         Assignment Process' for details on process.

         [                 ]

         Mutual Understanding

         Nortel's Premium Accounts - A Premium account is a Service account that
         has Enterprise Service Revenue greater than [ ]. Since Rainmaker is
         only responsible for Enterprise Service customers with service revenue
         less than [ ], Rainmaker will not contact these accounts without
         written authorization from Nortel. (Refer to Nortel Networks Premium
         Account list)

         Premium status is determined by several criteria. The major one is
         that, the [ ] annual revenue must result from maintenance on a central
         network and be supported by the same Technical Support Center at the
         customer's location. This may mean that not all maintenance business
         with an account qualifies for Premium status. Other non-related
         divisions, departments or entities of an account may be considered
         stand-alone business and may be referred to Rainmaker. For example,
         [ ]. The master name of [ ] is not enough information to determine if
         the particular contract is considered Premium.

     4.3  Rainmaker Fees and Customer Terms - Section 9.5, pg. 4 of Nortel
          Agreement 011145

          "Subject to Section 18.9 (Relationship of the Parties), Rainmaker may
          offer Service Contract to Customers at such fees and discounts as
          Rainmaker shall determine in its sole discretion, provided that any
          such discount shall reduce Rainmaker's margin with respect to such
          Service Contract by the amount of such discount. Rainmaker shall have
          the right to cancel any Customer's order for Service Contracts in the
          event that any such Customer fails to submit payment for such order,
          and Rainmaker will notify Nortel immediately upon such cancellation.
          if Rainmaker cancels any such order, Rainmaker shall bear the loss of
          the actual cost of the Service Contract provided to the customer for
          which the Customer has not paid. Nortel further agrees that, upon
          notice from Rainmaker, Nortel shall cease providing any services under
          a Service Contract to Customers who have defaulted on any payments due
          and owing to Rainmaker for such Service Contract."

          Mutual understanding

          Rainmaker processes annual payment for contracts. If a customer is
          unable to fulfill on an annual bill and requires a quarterly bill,
          Rainmaker will forward that client to Nortel for processing. Nortel
          will credit Rainmaker the GP from the customer contract fee. See
          section 7.5 for greater detail.

          Rainmaker will make every reasonable effort to collect funds for
          service contract orders. During the normal course of business,
          Rainmaker will follow its standard collections process to ensure
          timely and accurate collection of funds from Nortel's customers. If
          payment is not received from a customer within 120 days of invoice,
          Rainmaker will cancel the service agreement and notify Nortel to
          cancel said agreement.

          training, SAP query training, Service Program training, and General
          Contract Process training.

     5.3  Refund/Cancellation Policy

          Rainmaker will allow customers to cancel contracts per the Nortel
          Contract Agreement Termination clause.

          "Termination. Either party may terminate this Agreement if (i) the
          other party becomes insolvent, files or has filed against it a
          petition in bankruptcy, or ceases doing business; or (ii) the other
          party fails to cure a material breach of this Agreement within [ ]
          after receipt of written notice of such breach from the party not in
          default. Upon termination of this Agreement by Nortel Networks for
          Customer's breach, Nortel Networks may cancel all of Customer's
          unfulfilled orders without further obligation to furnish Services.
          Maintenance contracts that have been cancelled are eligible for a
          refund of billed and paid fees, less the [ ] cancellation period.
          Software contracts (service models BU2300 and SW8300 will not be c
          redited back to a customer if cancelled."

          Mutual Understanding

          If Rainmaker needs to issue a customer a credit for which they have
          invoiced, it will be done out of their SFA system. Since the amount
          due from Rainmaker Is processed out of the Clarify and SAP systems,
          this SFA credit memo will need to be processed by Nortel in their
          internal systems as well. In order for this credit to be deducted from
          the monthly amount due to Nortel, a credit memo request form must be
          completed and sent to Nortel to be processed in the SAP system. A
          credit memo will then be issued against the Rainmaker customer
          account, which will result in a reduction of the total Accounts
          Receivable balance due from Rainmaker to Nortel.

     5.4  Technical Support

          For non-contracted customers, technical support is available by

                      corresponding software model number if one applies. Upon
                      renewal, the SA-00 must be changed to SA0000 as the SA-00

                      obtained for exception items should be noted in Comments
                      section. This may include any/all EOL approvals, Board

               5.9.13 MONEY- Verify that the software lines/SW2300 do not carry
                      any dollars. Also check for lines that show $1.00 - those
                      lines will need to be researched. This usually means there
                      is no established Assurance Service pricing in the system.

                    received. Nortel will issue reimbursement checks to
                    Rainmaker on a weekly basis as needed. The check stub will
                    clearly indicate each Rainmaker invoice number and amount.
                    Each Nortel refund check should be payable to and mailed to:

                           Palatine, IL 60055-0937

                    o If the payment is in place of a PO and is intended to
                    activate a customer's contract, the contract must be booked
                    and activated upon Nortel's receipt of the payment. Nortel
                    will alert Rainmaker of the check and Rainmaker will
                    activate the contract. The activation cannot be based on
                    Rainmakers receipt of the payment from Nortel and the
                    customer's support should not be delayed during this payment
                    transition process.

                    Checks that come to Rainmaker that belong to Nortel

                    Rainmaker confirms they do not belong to Rainmaker.

                    If the payment is a live check, Rainmaker logs them in a
                    notebook (which the Rainmaker Collector has access to) and
                    mails them to:

                           Chicago, IL 60693

                    If checks were received through Rainmaker lockbox, the
                    Rainmaker Collector lists them in a spreadsheet and forwards
                    paperwork to the Rainmaker Accounts Payable Dept. The AP
                    department issues checks on a weekly basis as needed to
                    Nortel. Checks are payable to and mailed to:

                           Nortel Networks

                    The check stub clearly shows each Corporate Invoice number
                    and amount. The Rainmaker collector and the Nortel contact
                    will discuss any discrepancies by phone call.

                    overpayment from a Nortel Networks customer, Rainmaker will
                    refund the money to the customer using Rainmaker checks. The
                    refund check is sent directly to the customer name and
                    address with information advising the customer of the reason
                    for the refund.

               7.4  Vendor Name/Remit to Requirements for Customer Purchase
                    Orders (PO's)

                    In any case where the customer cannot or will not change the
                    vendor information to reflect NNESS (Rainmaker) at 1800
                    Green Hills Road, Scotts Valley, CA 95066 Nortel will
                    reassign the PO to Rainmaker.

               7.5  Quarterly Billing

                    If a customer wishes to continue with quarterly billing,
                    rather than the Rainmaker annual billing, Rainmaker will
                    forward the customer to Nortel for order processing. Nortel
                    will credit Rainmaker the GP from this contract. The Gross
                    Profit (GP) that Rainmaker would have normally received for
                    the contract will be billed to Nortel in a monthly invoice,
                    separate from the CPO, and Nortel will pay RMKR within [ ].
                    Nortel will supply a blanket PO that Rainmaker can bill
                    against each month.

               7.6  Contract Proration

                    Nortel does not offer contracts for less than a 1-year term.
                    If a customer has an existing maintenance agreement Nortel
                    will allow for additions to be prorated running coterminous
                    with the existing contract Prorating should be done to the
                    closest month.

               7.7  Discounts

                    Rainmaker may offer Service Contract to Customers at such
                    fees and discounts, as Rainmaker shall determine in its sole
                    discretion; provided that any such discount shall reduce
                    Rainmaker's margin with respect to such Service Contract by
                    the amount of such discount.

                    Example:
                            Rainmaker offers 10% discount to the customer.

                    Rainmaker is allowed to offer Multi-year discounts to their
                    customers without reducing their margin with respect to such
                    discount. The Multi-Year discounts are as follows:

                           [   ] for a 2-year contract
                           [   ] for a 3-year contract

                           Example:

                           Rainmaker sells 3-year contract for [ ] discount.

                           3-Year List:             [                ]
                           Less 3 year discount     [                ]
                           3 Year Net               [                ]

                           Amount due to Nortel: [                          ]

               Renewal Service Margin - [    ]
               Rescue Service Margin - [    ]

               Mutual Understanding

               A contract that is originally a direct renewal cannot become a
               rescue. If the renewal opportunity given to Rainmaker expires and
               it is renewed after the expiration date, the renewal margin of
               [ ] still applies.

               Rainmaker Systems plans to pull from these views three different
               ways to accommodate its data needs.

               8.1.1 An initial, all-inclusive pull of Rainmaker Systems renewal
                     and rescue eligible contract data.

               8.1.2 A quote only pull. This pull will query all Rainmaker
                     Systems flagged contracts with a status of "quote" only.
                     Furthermore, these records will be pulled every 60 minutes
                     and target only those quotes where a recent insertion or
                     change on a time stamp within a related table (such as
                     "last_update", "last_save_dt", "create_dt", last_mod_dt",
                     etc.) has occurred.

               8.1.3 A newly eligible and recently closed contract opportunity
                     pull. This will comprise only those contracts that have
                     become recently available to Rainmaker Systems and those
                     contracts that Rainmaker Systems has rescued or renewed.
                     The frequency of this pull is dependent on how often Nortel
                     will flag or convert eligible contracts to Rainmaker
                     Systems. The best case for Rainmaker Systems is pulling
                     once a day to avoid a backlog of closed opportunities.

               Note: We also plan to test a variety of actual working scenarios
               to verify updates, modifications, and inserts are properly
               captured.

               8.2  Rainmaker Extract Project Plan

               Objective

               Rainmaker Systems will be renewing hardware maintenance support
               contracts for Nortel's Global Enterprise Services group. The
               target market at this time is direct end users with annual
               contract revenue less than [ ] of Assurance Service revenue.

               Overview

               Rainmaker Sales reps will be creating quotes and updating
               customer contract records within Nortel's Clarify ClearContracts
               application. Rainmaker will be handling all billing, back office
               processes, and reporting through our own application. Contract
               data that has been flagged for Rainmaker will be extracted from
               Nortel's Clarify database to populate Rainmaker's systems.

               The data points required to support Rainmaker's processes have
               been identified and Nortel has defined the fields within the
               Clarify database which correspond to

               the requested data points. Views have been defined which
               incorporate these Rainmaker significant fields and include only
               contract records that have been flagged, by Nortel as assigned to
               Rainmaker.

               The Rainmaker extract must support near to real-time pulls of
               quote data from Nortel's production system in order to
               accommodate the customer sales process and pricing. Rainmaker
               intends to access the data through the defined views every thirty
               minutes during working hours targeting contracts that have been
               created or updated during that day (sysdate).

               The select from the rmkr views will be done through a stored
               procedure that will reside within Nortel's database. Rainmaker
               will call the procedure through a cron job on Rainmaker's side,
               scheduled to run every half hour.

               Rainmaker sales reps will update the comment field on the
               ClearContracts screen header more info tab to force an updated
               timestamp in table_contract_last_update.

               Specifications

               Clarify extract used to feed Rainmaker's SFA tool will be run out
               of reporting environment as an interim process until system
               modifications are put into Clarify Production allowing for a
               `delta extract' to be run in order to minimize the size of the
               data extract.

               The Clarify reporting environment refreshes daily at 6 hour
               intervals beginning at 10:00 Eastern time. The refresh takes
               approximately 30 minutes.

               Once Clarify modifications are complete, the extract may be run
               at more frequent intervals agreed upon by both parties. These
               extracts will be run so as not to negatively impact system
               performance.

               Rainmaker login information:

               USER ID: rainmaker_extract
               Password: Contact [   ], or [   ]
               Rainmaker contracts flagged with Clarify Administrator: [   ]

               Delta extract will be triggered by Rainmaker's changing the
               defined Clarify field: Header More Info tab. When changes are
               made to Clarify `More Info' tab in the header, the time stamp is
               changed, triggering the Rainmaker extract.
