NOW WHEREFORE, the parties agree to amend the Agreement as follows:

1.       End User Definition is modified to include U.S. Federal Government.

The following definition is modified:

         Product means Hardware and/or Software, as defined herein, included in
         Cisco's then-current published Global Price List, and are "commercial
         items" as defined under the Federal Acquisition Regulation ("FAR")
         2.101.

         Services means any maintenance, or technical support and any other
         services performed or to be performed by Cisco, as set forth in this
         Agreement or the Exhibits hereto and are "commercial items" as defined
         under the Federal Acquisition Regulation ("FAR") 2.101.

The following definition is hereby added:

         U.S. Federal Government is an executive, legislative or judicial branch
         of the United States Government or a U.S. Government corporation that
         was specifically formed and is currently existing under an Act of
         Congress, as well as any government owned contractor operated "GOCO"
         facilities and establishments.

2.       Scope 2.0, Subsection 2.2 Commercial Integration and Resale is modified
         to include U.S. Federal Government. Subsection 2.8 Resale to Government

                  Products or Services to the U.S. Federal Government End User
                  as expressly authorized in this Agreement. Integrator will not
                  Resell Products or Services under this Agreement through a
                  direct General Services Administration ("GSA") Schedule
                  contract.

                  2.8.1.   Integrator may resell Product and Services through

                           U.S. Federal Government subcontract arrangement,
                           Integrator must obtain Cisco's prior written approval
                           to resell such Product and Services. Cisco reserves
                           the right to determine if such IDIQ contract and
                           other prime or subcontract (if approved)
                           opportunities offer "Added Value" as defined herein.

8.0      PENETRATION DISCOUNT AND RESALE OF SERVICES.

         8.1      Discount for Initial Term. For the initial term of the
                  Equipment Schedule(s) to the Support Agreement, the price of
                  Services to Integrator is the then-current service list price
                  less the applicable discount based on Integrator's penetration
                  rate calculated as follows:

                  8.1.1    Determination of Service Penetration Rate. Service
                           penetration rate is calculated by Integrator's total
                           number of Products covered by Cisco brand services
                           (per Attachment 1) as a percentage of the total
                           number of Products purchased over the most recent
                           period of twelve (12) months.

                  8.1.2    Cisco will review Integrator's service sales
                           penetration rate at the time the Integrator renews
                           the Agreement with Cisco and at six-month intervals
                           during the term of the Agreement. Cisco reserves the
                           right to adjust Integrator's resale discount at the
                           time of review. Any adjustment to the resale discount
                           will be communicated in writing to the Integrator by
                           Cisco.

                  8.1.3    Integrator must have purchased Product for a minimum
                           of twelve months in order to determine the
                           penetration rate. If Integrator has less than twelve
                           months of Product purchases, Integrator's discount
                           will be ten percent (10%).

                  8.1.4    Integrator's discount on Services shall bb determined
                           by calculating the rate of Services penetration based
                           on the total amount of Product purchased by
                           Integrator from Cisco plus the total amount of
                           Product purchased by Integrator from Distributor(s).

         8.2      Upon renewal of the Equipment Schedule(s), the discount shall
                  be the corresponding discount associated with the Penetration
                  Rate.

         8.3      The discounts listed above do not apply when Integrator
                  resells Cisco brand services for Other Product. Integrator
                  discount for Other Product shall be fifteen percent (15%).

         8.4      The discounts listed above do not apply when Integrator
                  resells Other Services. Integrator Discount for Other Services
                  shall be fifteen (15%) percent.

         8.5      All Services are invoiced annually in advance, payable thirty
                  (30) days from the invoice date in U.S. Dollars unless
                  otherwise agreed to in the Agreement.

         8.6      All prices in the Equipment Schedule(s) are exclusive of any
                  taxes and duties which, if applicable, shall be paid by
                  Integrator. Applicable taxes are billed as a separate item. In
                  addition, the following items will be billed to Integrator:
                  (i) time and material fees for any additional services
                  performed by Cisco; and (ii) Product list price of replaced
                  Product not returned by End User pursuant to the terms as set
                  forth on the applicable Program Description.

         8.7      Integrator is free to determine its prices for Services to End
                  Users unilaterally. Integrator understands that neither Cisco,
                  nor any employee or representative of Cisco, may give any
                  special treatment (favorable or unfavorable) to Integrator as
                  a result of Integrator's selection of resale prices. No
                  employee or representative of Cisco or anyone else has any
                  authority to specify what Integrator's resale prices for the
                  Services

                  discretion with respect to the Services.

         8.8      Support for Other Product. Integrator may support Other
                  Product under the following conditions: Integrator provides
                  Cisco (i) Notice to support Other Product; and (ii) a letter
                  from the End User including notification for Service from the
                  Integrator, which letter must include a list of the Product(s)
                  and serial numbers) to be supported.

         8.9      Unsupported End User List. Integrator must provide information
                  on all End Users who have purchased Product from Integrator
                  without also purchasing Services. In the event Integrator does
                  not provide this information for all Products, in each
                  quarter, Cisco will provide a report identifying the model
                  types and serial numbers of Product purchased by Integrator
                  for which the following information is required: End User name
                  and End User address and phone number. Integrator will
                  complete and return this information to Cisco no later than
                  twenty (20) business days from the date the report is provided
                  to Integrator.

                                    designated location. For Product that has
                                    been advance replaced pursuant to the
                                    Product warranty terms, Integrator shall
                                    return failed/defective Product within ten
                                    (10) days of receipt of the replacement
                                    Product; otherwise, Product will be invoiced
                                    to Integrator at the then current list
                                    price.

                                              alterations made to the Product.
                                              Product returned to Cisco will
                                              conform in quantity and serial
                                              number to the RMA request.

         4.6      Unsupported End User List. If Integrator elects not to support
                  Product under this Exhibit, Integrator shall refer End User
                  information, including but not limited to End User name,
                  address and phone number to Cisco at the time of Product
                  purchase or renewal of support via any of the means described
                  in section 1.4 above. If Product becomes unsupported due to
                  End User decision at some point subsequent to initial
                  deployment, Integrator shall refer End User information to
                  Cisco within 90 days of equipment becoming unsupported.

5.0      PRICE AND PAYMENT TERMS.

         5.1      DISCOUNTS.

                  5.1.1    UNIT-BASED MODEL. The price of Services to Integrator
                           for a period of twelve months from the Effective Date
                           ("Unit-Based Measurement Period") shall be calculated
                           by applying Cisco's then current service list price
                           less the applicable discount based on Integrator's
                           ability to have attached Service to Product purchased
                           ("Attach Rate") over the previous twelve (12) month
                           period on a units-based method ("Unit-Based") shown
                           below.

                           Determination of Unit-Based Attach Rate. Unit-Based
                           Attach Rate is established by calculating
                           Integrator's total number of Products covered by
                           Cisco brand services (per Attachment A) as a
                           percentage of the total number of Products purchased
                           over the most recent period of twelve (12) full
                           calendar months.

                  5.1.2    REVENUE-BASED MODEL. The price of Services to
                           Integrator for a period of twelve months from
                           expiration of the Unit-Based Measurement Period and
                           for subsequent twelve month period(s) ("Revenue-Based
                           Measurement Period") shall be calculated by applying
                           Cisco's then-current service list price less the
                           applicable discount based on Integrator's ability to
                           have attached Service to Product purchased ("Attach
                           Rate") over the previous twelve (12) month period on
                           a revenue based method ("Revenue-Based") shown below.

                           Determination of Revenue-Based Attach Rate. Attach
                           Rate is calculated by Integrator's total monetary
                           value (U.S. Dollar) of Service actually sold over a
                           period of twelve months as a percentage of the total
                           monetary (U.S. Dollar) value of Service that would
                           have been payable had support attached to every
                           device purchased over the same twelve month period,
                           based on SMARTnet NBD list price. The Attach Rate
                           calculation only applies to service coverage on
                           Product originally sold by the Integrator and any
                           multi-year service contracts are amortized over the
                           life of the service coverage. Other Product is not
                           covered.

                           Examples:

                           Integrator purchased 8 devices (6 of Device A and 2
                           of Device B) and sold support on 4 of Device A and 2
                           of Device B. Regardless of the level of service
                           actually sold on the device, SNT NBD pricing is used
                           to determine coverage value for calculating Attach
                           Rate. The NBD price for the Device A is $50 and for
                           Device B is $10. The Attach Rate is actual Service
                           sold (4x$50 plus 2x$10) divided by total dollar value
                           of Service (6x$50 plus 2x$10). 220/320=69% represents
                           the Attach Rate with a corresponding discount of 20%.

                           Multi-Year Scenario: Integrator purchased 1 device (1
                           of Device A) and sold 3 year support on the 1 device.
                           The NBD three year price for the Device A is $150.
                           The Attach Rate is calculated by dividing the
                           multi-year price by the number of years covered (in
                           this case, three years or $150/3) and crediting the
                           first year Attach Rate actual performance and Attach
                           Rate opportunity ($50). The Attach Rate actual
                           performance is the one year NBD value of service sold
                           ($50) divided by the one year NBD value of the total
                           dollar value of Service ($50) and represents an
                           Attach Rate of 100% with a corresponding discount of
                           25%.

                  5.1.3    Cisco will review Integrator's actual service sales
                           Attach Rates at the time the Integrator renews the
                           Agreement with Cisco and at six month intervals using
                           a Revenue-Based Model approach during the term of the
                           Agreement. Cisco reserves the right to adjust
                           Integrator's resale discount at the time of review.
                           Any adjustment to the resale discount will be
                           communicated in writing to the Integrator by Cisco.

                  5.1.4    Integrator must have purchased Product for a minimum
                           of twelve months in order to determine the Attach
                           Rate. If Integrator has less than twelve months of
                           Product purchases, Integrator's discount will be ten
                           percent (10%).

                  5.1.5    Upon renewal of the Equipment List(s), the discount
                           will be the corresponding discount associated with
                           the Attach Rate.

                  5.1.6    The discounts listed above do not apply when
                           Integrator resells Cisco brand services for Other
                           Product. Integrator discount for Other Product shall
                           be fifteen percent (15%).

                  5.1.7    The discounts listed above do not apply when
                           Integrator resells Advanced Services. Integrator
                           Discount for Advanced Services shall be ten (10%)
                           percent.

         5.2      All Services are invoiced annually in advance and payable
                  within thirty (30) days from the invoice date in U.S. Dollars
                  unless otherwise agreed to in the Agreement in writing.

         5.3      All prices in the Equipment List(s) are exclusive of any taxes
                  and duties which, if applicable, shall be paid by Integrator.
                  Applicable taxes are billed as a separate item. In addition,
                  the following items will be billed to Integrator: time and
                  material fees and Product list price of replaced Product not
                  returned pursuant to the terms of End User's Support
                  Agreement.

         5.4      This Agreement may be terminated by Cisco and/or Cisco may
                  suspend its performance immediately upon Notice if (i)
                  Integrator does not provide the Unsupported End User List
                  pursuant to Section 4.3 within thirty (30) days after the end
                  of the previous quarter and after Notice from Cisco or (ii)
                  Integrator fails to pay for the Services when due and fails to
                  make such payment within fifteen (15) days after Notice from
                  Cisco of such past due payment. Notwithstanding the above,

                  shall have the right to seek payment for Services directly
                  from the End User in the event Integrator does not remit
                  payment to Cisco pursuant to the payment terms.

         5.5      Integrator is free to determine its resale prices
                  unilaterally. Integrator understands that neither Cisco, nor
                  any employee or representative of Cisco, may give any special
                  treatment (favorable or unfavorable) to Integrator as a result
                  of Integrator's selection of resale prices. No employee or
                  representative of Cisco or anyone else has any authority to
                  specify what Integrator's resale prices for the Services must
                  be, or to inhibit in any way, Integrator's pricing discretion
                  with respect to the Services.

         5.6      Support for Other Product. Integrator may support Other
                  Product under the following conditions: Integrator provides
                  Cisco (i) a request to support Other Product and (ii) a letter
                  from the End User including a request for Service from the
                  Integrator and a list of the Product(s) and serial number(s)
                  to be supported.

6.0      GENERAL.

         6.1      Entitlement. Integrator acknowledges that an End User is
                  entitled to receive support services only on Product for which
                  Integrator has paid the applicable license and support fees to
                  Cisco. Integrator agrees to assist Cisco with enforcement of
                  End User entitlement as necessary.

         6.2      Disclosure of Contract Information.Integrator acknowledges and

                  in this Exhibit or Integrator's Agreement number be disclosed
                  to any third party.

         6.3      Representations and Warranties. Integrator shall not make any
                  representations or warranties on behalf of Cisco, except as
                  expressly authorized herein or as expressly authorized by
                  Cisco in writing. Neither Integrator nor Cisco will make any
                  obligation to End Users on behalf of the other, nor commit the
                  resources of the other to End Users.

         6.4      Independent Contractors. The relationship of Cisco and
                  Integrator established by this Exhibit is that of independent
                  contractors, and nothing contained in this Exhibit shall be
                  construed to (i) give either party the power to direct and
                  control the day-to-day activities of the other, (ii)
                  constitute the parties as joint venturers, co-owners or

                  responsibility of Integrator. All sales and other agreements
                  between Integrator and its End Users are Integrator's
                  exclusive responsibility and shall have no effect on
                  Integrator's obligations under this Agreement. Integrator
                  shall be solely responsible for, and shall indemnify and hold
                  Cisco free and harmless from, any and all claims, damages or
                  lawsuits {including Cisco's attorneys' fees) arising out of
                  the acts of Integrator, its employees or its agents.

         6.5      Indemnification. Integrator hereby indemnifies and holds Cisco
                  harmless from any claim, loss, damage or expense, including

                                   APPENDIX A
              CISCO PROBLEM PRIORITIZATION AND ESCALATION GUIDELINE

To ensure that all problems are reported in a standard format, Cisco has
established the following problem priority definitions. These definitions will
assist Cisco in allocating the appropriate resources to resolve problems.
Integrator must assign a priority to all problems submitted to Cisco.

PROBLEM PRIORITY DEFINITIONS:

         Priority 1:       An existing network is down or there is a
                           critical impact to the End User's business operation.
                           Cisco, Integrator and End User will commit full-time
                           resources to resolve the situation.

         Priority 2:       Operation of an existing network is severely
                           degraded, or significant aspects of the End User's
                           business operation are being negatively impacted by
                           unacceptable network performance. Cisco, Integrator
                           and End User will commit full-time resources during
                           Standard Business Hours to resolve the situation.

         Priority 3:       Operational performance of the network is
                           impaired white most business operations remain
                           functional. Cisco, Integrator and End User are
                           willing to commit resources during Standard Business
                           Hours to restore service to satisfactory levels.

         Priority 4:       Information or assistance is required on Cisco
                           product capabilities, installation, or configuration.
                           There is clearly little or no impact to the End
                           User's business operation. Cisco, Integrator and End
                           User are willing to provide resources during Standard
                           Business Hours to provide information or assistance
                           as requested.

Cisco encourages Integrator to reference this guide when Integrator-initiated
escalation is required. If Integrator does not feel that adequate forward
progress or the quality of Cisco service is satisfactory, Cisco encourages
Integrator to escalate the problem ownership to the appropriate level of Cisco
management by asking for the TAC Duty Manager.

Note:    Priority 1 problem escalation times are measured in calendar hours 24
         hours per day, 7 days per week. Priority 2, 3 and 4 escalation times
         correspond with Standard Business Hours. The Cisco Manager to which the
         problem is escalated will take ownership of the problem and provide the
         Integrator with updates. Cisco recommends that Integrator-initiated
         escalation begin at the Customer Engineering Manager level and proceed
         upward using the escalation guideline shown above for reference. This
         will allow those most closely associated with the support resources to
         correct any service problems quickly.
