3.   Grant of Rights to NEC:
     -----------------------

     a)   Licensed Products:  On or before February 16, 2001, the parties will
          -----------------
          agree to standards for the Licensed Products and include said
          standards on Schedule A (the "Standards"). As soon as practical
          thereafter, NetSolve shall deliver to NEC the Licensed Products,
          within thirty (30) days after NEC's receipt of the Licensed Products
          from NetSolve, NEC will inspect the Licensed Products for conformity
          with the Standards. NEC shall notify NetSolve in writing within such
          thirty (30) day period (subject to extension by force majeure) as to
          whether the licensed Products conform to such Standards. If the
          Licensed Products conform to such Standards, NEC may use the Licensed
          Products pursuant to Section 3b) below and the other provisions of
          this Agreement. If the Licensed Products do not conform to such
          Standards, NEC must identify specific defects that cause the Licensed
          Products not to meet the Standards. If NEC does not provide written
          notice of specific defects within said thirty (30) day period, the
          initial U.S. $* installment of the License Fee shall not be refundable
          to NEC, NetSolve shall have thirty (30) days (subject to extension by
          force majeure) from its receipt of written notice of such defects to
          cure the defects. If NetSolve timely offers a cure for the defects,
          NEC will again inspect the Licensed Products for conformity with the
          Standards within thirty (30) days. If the Licensed Products conform to
          such Standards, NEC may use the Licensed Products pursuant to Section
          3b) below and the other provisions of this Agreement. If the Licensed
          Products, as modified, do not conform to such Standards, this
          Agreement shall terminate immediately upon NEC's written notice of
          nonconformity and NEC shall have no right to use the Licensed Products
          in any manner and shall immediately return the Licensed Products to
          NetSolve. Notwithstanding the foregoing, if NetSolve is unable to cure
          the defects identified by NEC in accordance herewith, NetSolve shall
          refund the U.S. $* installment of the License Fee to NEC. If NEC does
          not accept the Licensed Products due to problems within NEC's control,
          the U.S. $* initial installment of the License Fee shall be non-
          refundable to NEC. If the defects are attributable to causes outside
          the control of either party, then U.S. $* of the initial installment
          of the License Fee shall be refunded to NEC.

     b)   Grant of License:  NetSolve hereby grants NEC an exclusive and non-
          ----------------
          transferable right to use the Licensed Products in object code form
          solely for the purpose of rendering NEC Services to Customers and for
          the management of NEC and its subsidiaries' own network (the
          "Permitted Use"). In addition, NEC may make a copy of software
          included within the Licensed Products for enhancing NEC Services for
          capacity, performance, and redundancy reasons and for archival
          purposes, and of documentation included within the Licensed Products
          to the extent reasonably necessary for exercising the rights granted
          under this Section 3b) In addition, NEC have the right to translate
          NetSolve copyrighted documentation from English to Japanese.
          Notwithstanding anything else herein to the contrary, NEC shall not
          use the Licensed Products for, or make available services involving
          the Licensed Products to, any entity that does not qualify as a
          Customer as defined above. Nothing in this Agreement shall prevent
          NetSolve from granting rights in the Licensed Products to other
          parties for any other purpose, including the provision of network
          management services to entities which are not Customers but, so long
          as NEC keeps exclusivity under c) below, NetSolve is prohibited to
          license the Licensed Products for Permitted Use to Customers in Japan.
          The exclusive nature of NEC's rights granted hereunder with respect to
          the Permitted Use shall be subject to Section c) below. NEC is
          expressly prohibited from decompiling, disassembling, or reverse
          engineering the Licensed Products in any manner whatsoever, and NEC is
          expressly prohibited from designing another product or system,
          including, without limitation, a

          competing product, that is based upon, any of the Licensed Products;
          provided, however, that NEC may continue to provide its existing
          network management service in its current form.

     c)   Exclusive Right:  In order to maintain the exclusive nature of the
          ---------------
          right to use the Licensed Products for the Permitted Use as described
          in Section b) above, NEC must pay NetSolve minimum annual payments in
          each of the years during the three year period described below of
          US$*, US$* and US$*, respectively(the "Exclusivity Amounts"). For this
          purpose, the first year shall begin upon the earlier of completion of
          the installation of NEC's Network Operation Center in Japan or June
          30, 2001, unless delay of installation of the NEC Network Operations
          Center is due to NetSolve's fault, in which case the Initiation Date
          shall be extended to the extent of the delay caused by NetSolve. The
          Exclusivity Amounts shall be comprised of the One Time License Fee
          (amortized over a 36 month life commencing with the Initiation Date),
          Royalty Fees, and Maintenance Fees due to NetSolve under this
          Agreement as described on Schedule B attached hereto and made a part
          hereof for all purposes by NEC. In the event NEC has not incurred the
          Exclusivity Amounts in any year, NEC shall have the right to either
          (i) pay the differences between the actual amounts incurred and the
          applicable Exclusivity Amount within thirty (30) days after the end of
          the applicable year period, or (ii) lose its exclusive right described
          in Section 3b) above while retaining its license rights as set forth
          herein to render NEC services to Customers on a non-exclusive basis.

     d)   Governmental Approvals: Notwithstanding anything herein seemingly to
          ----------------------
          the contrary, this Agreement, the license granted herein and the
          delivery of the Licensed Products are conditioned on the attainment of
          any required governmental approvals relating to the importation or
          exportation of the Licensed Products.

4.   License Fees:
     -------------

     a)   License Fees and Charges:  NEC agrees to pay the License Fee, Royalty
          ------------------------
          Fees and Maintenance Fees (collectively, the "Fees") as set forth in
          Schedule B hereto. Except as otherwise provided herein, the Fees shall
          not be increased during the initial three year Term of this Agreement.
          After the initial three year term of this Agreement, any increase in
          NetSolve's Fees shall not be effective until ninety (90) days after
          notification by NetSolve to NEC. Any such increase shall apply only to
          devices or services using the Licensed Products which are ordered
          after the date of NetSolve's notice of Fee increase. In the event of a
          Royalty and/or Maintenance Fee decrease, all devices or services using
          the Licensed Products which had been ordered but not implemented as of
          the date of NetSolve's notice of Fee decrease will be adjusted to take
          into consideration the fee decrease. NetSolve agrees to consider, in
          good faith, adjustments to the Fees in the event that the Fees at any
          point in time do not agree with market conditions.

     b)   Minimum Fees During Term.  NEC agrees that, during the initial three
          ------------------------
          (3) year term of this Agreement, it shall pay NetSolve minimum Fees of
          US $* ("Minimum Term Fee"). If, upon the completion of the initial
          three (3) year term of this Agreement, or upon the earlier termination
          of this Agreement for any reason (other than NEC not accepting the
          Licensed Products pursuant to the provisions of, and the procedure set
          forth in, Section 3a) above or if NEC terminates the agreement
          pursuant to Section 9d), the aggregate Fees actually paid by NEC to
          NetSolve hereunder is less than the Minimum Term Fee, NEC shall
          promptly pay NetSolve the difference between the aggregate Fees
          actually paid and the Minimum Term Fee.

     c)   Taxes and Charges: The Fees for the Licensed Products do not include
          ------------------
          any taxes except income or withholding tax, duties or any other
          charges of any kind that may be applicable to the purchase or
          transportation, importation or exportation of the Licensed Products.
          In the event the Japanese Government imposes any income or withholding
          tax on NetSolve and requires NEC to withhold such tax from the payment
          of the Fees, NEC shall notify NetSolve in sufficient time in advance
          of such withholding to allow NetSolve to fully exercise any and all
          appeal rights with respect to the assessment of such tax and
          withholding. If, after such appeal NEC is required to withhold from
          the payments hereunder, or if NetSolve chooses not to appeal such tax
          and withholding, NEC may withhold from the said payment in accordance
          with legal requirements. NEC shall provide NetSolve a tax receipt
          received from such tax authority and shall assist NetSolve in claiming
          and receiving a foreign tax credit. All

          for any special packing requested by NEC, will be paid by NEC. NEC
          will also bear all applicable taxes, duties and similar charges,
          including any import or export duties or similar charges that may be
          assessed with respect to the delivery of the Licensed Products to NEC.

          Account Name:  *
          Account#:      *

5.   New Product Capabilities:
     ------------------------

     NetSolve agrees to offer to NEC any new product capabilities incorporating
     or relating to the Licensed Products on terms and conditions mutually
     agreeable to the parties hereto. NEC may request NetSolve to modify the
     Licensed Products to perform additional functions and NetSolve will use
     good faith efforts to provide NEC cost estimates for the development of
     such modifications; provided, however, that NetSolve shall have no
     obligation to develop or provide such modifications. If NetSolve does not

          otherwise not covered by, the limited warranty provided herein, NEC
          shall reimburse NetSolve at the rates set forth in Schedule C hereto,
          for all expenses incurred by NetSolve in evaluating and dealing with

     d)   Software Fixes:  During the term of this Agreement, NetSolve shall
          --------------
          provide NEC with notice of any Software Fixes and shall provide any
          such Software Fix per the rates identified for Software Maintenance
          Fee in Schedule B.

     e)   Other Support:  Any customization or support in addition to that
          -------------
          specified herein may be provided by NetSolve at NetSolve's sole
          discretion, at the rates and terms mutually agreed upon in each
          instance.

9.   Termination:
     ------------

     NetSolve acknowledges that NEC will expend substantial effort and resources
     in creating and maintaining the NEC Services and Customer base.
     Accordingly, NetSolve agrees that in the event of a termination of this
     agreement (except for termination as set forth in subsection a) below),
     that it will provide NEC sufficient time not to exceed 24 months to
     transition the NEC Services to another provider and minimize any negative
     impact on NEC's Customer base:

     a)   Termination for Cause:  If either party materially defaults in the
          ---------------------
          performance of any provision of this Agreement, then the non-
          defaulting party may give written notice to the defaulting party that
          if the default is not cured within thirty (30) days from the date of
          such notice the Agreement will be terminated. If the non-defaulting
          party gives such notice and the default is not cured during such
          thirty (30) day period, then the non-defaulting party may terminate
          the Agreement at the end of that period.

     b)   Termination for Insolvency:  This Agreement may be terminated,
          --------------------------
          immediately upon: (i) the institution by or against either party to
          the Agreement of insolvency, receivership or bankruptcy proceedings or
          any other proceedings for the general settlement of its debts, (ii)
          either Party's general assignment for the benefit of creditors, or
          (iii) either party's dissolution or ceasing to do business. Such
          termination shall be effective upon the delivery of written notice
          from the party not involved in any such proceedings or actions.

     c)   Termination for Change of Control:  This Agreement may be terminated
          ---------------------------------
          by either party if the identity of the other party or the nature of
          its business is materially changed by bulk transfer of assets, sale of
          its business, transfer of 50.1% or more of its outstanding stock, or
          merger to, by or with, as the case may be, a business entity that
          provides products and services in direct competition with the
          terminating party's products or services, and in the terminating
          party's sole judgment continuing the relationship with the surviving
          entity would create a conflict of interest (each, a "Change of
          Control"). Such termination must be given by written notice provided
          within thirty (30) days of being notified by the party with the Change
          of Control. In addition, NEC may terminate this Agreement in the event
          NEC determines, in its sole discretion, to discontinue its business
          relating to the Licensed Products within 1 year after the execution of
          this Agreement by providing NetSolve with ninety (90) days written
          notice in advance.

     d)   Payments by NEC Upon Termination:  Upon the termination of this
          --------------------------------
          Agreement, for any reason, NEC shall promptly pay NetSolve the
          following: (i) the amount required under Section 4b), if any, relating
          to the Minimum Term Fee (provided, however the Minimum Term Fee will
          be waived provided NEC terminates this Agreement on the first (1st)
          anniversary of the acceptance of the Licensed Products due to NEC's
          termination of its NEC Services business; (ii) any unpaid portion of
          the License Fee (unless the termination is the result of NEC not
          accepting the Licensed Products in accordance with the provisions of,
          and the procedure set forth in, Section 3a)); (iii) all Royalty Fees
          for NEC Services sold through the date of termination; and (iv) any
          unpaid portion of the Software Maintenance Fee for the year of the
          termination. Except for such payments, neither party shall be liable
          to the other for damages of any kind, including incidental or
          consequential damages, on account of the termination of this
          Agreement, and both parties waive any right they may have to receive
          any compensation or reparations on termination or expiration of this
          Agreement, which includes, but is not limited to, loss of goodwill,
          prospective profits

                                       6

          or anticipated orders, or an account of any expenditures, investments,
          leases or commitments made by either NetSolve or NEC.

     e)   Return of Licensed Products:  NEC shall, promptly upon the termination
          ---------------------------
          of this Agreement for any reason (regardless of the party causing or
          effecting such termination), cease all use of the Licensed Products
          and return the Licensed Products to NetSolve at NEC's sole cost and
          expense. NEC shall not retain any portion of the Licensed Products or
          any copies thereof. In the event that, following the termination of
          this Agreement, NEC discovers that it possesses any portion of the
          Licensed Products or any copies thereof, NEC will promptly return it
          to NetSolve at NEC's sole cost and expense. Notwithstanding the
          foregoing, if NetSolve should terminate this Agreement for any reason
          other than NEC's default or insolvency, NEC shall be entitled to (i)
          maintain for existing Customers for a period of three (3) years as of
          the termination date, and (ii) to sell to now Customers for a period
          of two (2) years as of the termination date and NEC shall be obligated
          to continue to pay the applicable Fees as set forth on Schedule B with
          respect to such continued service.

     f)   Survival of Certain Terms: The provisions of Sections 4, 7c), 7d), 9,
          -------------------------
          10, 11, 12, 13, 14, and 16a shall survive the termination of this
          Agreement for any reason. All other rights and obligations of the
          parties shall cease upon termination of this Agreement.

10.  Limitations On Liability:
     -------------------------

     EXCEPT FOR DAMAGES CAUSED BY A BREACH OF PROVISIONS OF SECTION 11 OR
     SECTION 13 BELOW, IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER
     PARTY OR ANY OTHER ENTITY FOR COSTS OF COVER, LOST PROFITS OR ANY OTHER
     SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE OR INDIRECT DAMAGES, HOWEVER
     CAUSED AND ON ANY THEORY OF LIABILITY, ARISING OUT OF THIS AGREEMENT, EVEN
     IF THE OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
     THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL
     PURPOSE OF ANY LIMITED REMEDY. ALL AGREEMENTS BETWEEN NEC AND CUSTOMERS
     SHALL INCLUDE PROVISIONS CONSISTENT WITH THIS SECTION 10 AND NEC SHALL
     INDEMNIFY AND HOLD NETSOLVE HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS,
     CAUSES OF ACTION, AND COSTS OF ANY KIND (INCLUDING ATT0RNEYS' FEES)
     INCURRED BY NETSOLVE IN CONNECTION WITH A CLAIM BY A CUSTOMER INCONSISTENT
     WITH THE PROVISIONS OF THIS SECTION 10.

11.  Proprietary Rights and Confidentiality:
     --------------------------------------

     a)   Proprietary Rights:  NEC acknowledges that, as between NEC and
          ------------------
          NetSolve, the Licensed Products are owned exclusively by NetSolve. NEC
          shall not claim, nor shall it have under any circumstances, any rights
          in, to or under the Licensed Products, product lines that include the
          Licensed Products, or any of NetSolve's patents, trademarks, service
          marks, trade names, inventions, copyrights, know-how, trade secrets or
          other intellectual and/or proprietary information, except for the
          limited right to use the Licensed Products as expressly permitted in
          this Agreement. As between NEC and NetSolve, NetSolve owns the entire
          and complete right, title, and interest in the Licensed Products,
          including but not limited to, all copyright, patent and other
          proprietary rights. The license and use by NEC of any of these
          proprietary rights is authorized only for the purposes expressly set
          forth herein, and upon termination of this Agreement for any reason
          such authorization shall immediately cease. NetSolve expressly
          disclaims any and all implied licenses to NEC with respect to any of
          its intellectual property and other rights related to the Licensed
          Products including, without limitation, all patent, trademark, service
          mark, trade name, copyright, and trade secret rights.

     b)   Confidentiality:  The parties acknowledge that by reason of their
          ---------------
          relationship to each other hereunder each will have access to certain
          information and materials concerning the other's business, plans,
          customers, processes, technology and/or products that is confidential
          and proprietary to that party ("Confidential Information"). The
          parties acknowledge further that disclosure of any such Confidential
          Information to third parties would cause irreparable harm.
          Accordingly, each party agrees that it will

                                       7
<PAGE>

          not use in any way for its own account or the account of any third
          party, nor disclose to any third party, any Confidential Information
          of the other party and shall take every reasonable precaution to
          protect the confidentiality of such Confidential Information. All
          information disclosed by one party to the other party hereunder which
          the disclosing party intends to be treated as Confidential Information
          shall be clearly marked. The parties acknowledge and agree that the
          Licensed Products and all surrounding information and documentation
          constitute the valuable Confidential Information of NetSolve. Upon
          request by either party, the other party shall advise whether or not
          it considers any particular information or materials to be
          confidential. In the event of termination of this Agreement for any
          reason, there shall be no use or disclosure by a party of any
          Confidential Information of the other party for a period of five (5)
          years from the date of such termination, and neither party shall
          produce or develop, nor have produced or developed, any product,
          software, service, device, component or assembly utilizing any of the
          other party's Confidential Information. Notwithstanding the prior
          sentence or anything else herein to the contrary, in no event shall
          NEC ever have the right to disclose to others or to use NetSolve's
          Confidential Information, either before or after termination of the
          Agreement, that remains a trade secret of NetSolve or that is
          protected through some other form of intellectual property protection
          such as, without limitation, patent, trademark or copyright
          protection. A recipient of Confidential Information from the other
          party shall not use the Confidential Information, or any part thereof
          in any manner for any purpose other than in connection with conducting
          business with or performing business in accordance with this
          Agreement. To the extent that a recipient of Confidential Information
          from the other party has or does develop intellectual property rights
          related to or based, in any manner, on such Confidential Information,
          such recipient hereby irrevocably grants the other party a
          nonexclusive, worldwide, fully paid-up license to any and all such
          intellectual property rights. Such intellectual property shall
          include, at least, all inventions, whether patentable or not,
          developments, improvement, trade secrets, trademarks, trade names,
          copyrights, patent applications, patents, and the like. At the
          termination of this Agreement, each party shall return all copies and
          associated materials, whether in tangible or electronic form,
          disclosing any Confidential Information of the other party to such
          other party. At such time, neither party shall retain copies or have
          access, either directly or through a third party, to the other party's
          Confidential Information. Both parties shall have the right to audit
          the other party to ensure compliance with the prior sentence and to
          request and receive a written certificate from an officer of the other
          party certifying compliance therewith.

     c)   Injunctive Relief:  Both parties acknowledge, understand, and agree
          -----------------
          that the breach or any provision of this Section 11 will result in
          immediate and irreparable harm to the other party and that monetary
          damages alone will be inadequate to compensate the other party for
          such breach. Accordingly, both parties agree that in such a case, the
          aggrieved party shall be entitled to any remedies available to it at
          law or in equity, including, without limitation, the right to
          temporary, preliminary, and permanent injunctive relief and specific
          performance to enforce the terms of this Section 11 without the
          necessity of proving inadequacy of legal remedies or irreparable harm,
          or posting bond.

12.  Trademarks and Trade Name:
     -------------------------

     a)   NetSolve and NEC each have and may adopt from time to time certain
          trademarks, service marks and trade names ("Trademarks"). Upon the
          prior written approval of NetSolve, NEC shall have the limited right
          to use the associated NetSolve Trademarks in connection with the
          Licensed Products either alone or in conjunction with any other
          Trademarks of NEC, solely in connection with marketing and
          distributing the Licensed Products to Customers within express
          guidelines established by NetSolve for such purpose. NEC shall make
          every reasonable effort to display recognition that NetSolve's
          technologies and processes are used in connection with the Licensed
          Products. Any use of the NetSolve name and logo or any of NetSolve's
          other Trademarks by NEC shall inure to the benefit of NetSolve, and
          any ownership that NEC may obtain though its use of the NetSolve name
          and logo or any of NetSolve's other Trademarks is hereby assigned
          fully and completely to NetSolve. Except as otherwise provided in this
          Section 12, nothing contained in this Agreement shall grant to either
          party any right, title or interest in the other party's Trademarks. At
          no time during the term of this Agreement shall either party challenge
          or assist others to challenge the other party's Trademarks or the
          registration thereof or attempt to register any Trademarks, marks or
          trade names confusingly similar to those of the

                                       8
<PAGE>

          other party. NEC shall have the right to name and/or register
          Trademarks for Licensed Products, provided that such names and/or
          Trademarks do not infringe on any names and/or Trademarks of NetSolve.
          Except for the use of the NEC name, NetSolve shall have a fully paid-
          up, royalty free, worldwide license to use any Trademark NEC uses or
          registers in connection with the Licensed Products.

13.  Patent, Copyright and Trademark Indemnity:
     -----------------------------------------

     a)   Representation:  NetSolve represents and warrants either that to the
          --------------
          best of NetSolve's actual knowledge: (i) the Licensed Products
          prepared for or submitted to NEC under this Agreement is original and
          no portion of such Licensed Products, or the use or distribution of
          copies thereof violates or is protected by a patent, copyright or
          other proprietary right of any third party in the United States or
          Japan; or (ii) to the extent third party software is incorporated
          within the Licensed Products, NetSolve has the right to incorporate
          said third party software within the Licensed Products and to grant to
          NEC all the rights and licenses to the Licensed Products expressly
          provided for and granted under this Agreement. To the extent third
          party software is used in conjunction with the Licensed Products, NEC
          must procure its own licenses with respect to such third party
          software.

     b)   Indemnification:  Except as provided below, NetSolve will indemnify,
          ---------------
          hold harmless and defend NEC, at NetSolve's expense, against any and
          all claims that any Licensed Products as provided by NetSolve
          hereunder infringes any published Japanese or U.S. patent, copyright,
          trademark or trade secret or other proprietary right of any third
          party in the U.S. or Japan. In such event NEC shall promptly notify
          NetSolve of any such claim after receiving service of process, provide
          all reasonable assistance to NetSolve and allow NetSolve to control
          any resulting litigation and/or settlement negotiations. If a claim of
          infringement described in this Section 13b does occur, or in
          NetSolve's opinion is likely to occur, NEC will permit NetSolve, at
          its option and expense:

          i)   To modify the system or Licensed Products so that it no longer
               infringes while performing substantially the same function and
               provided that it has minimal impact on the current Customers;

          ii)  To obtain for NEC the right to continue using the system or
               Licensed Products; or,

          iii) If i) or ii) are not reasonably procurable, require NEC to return
               the System or Licensed Products.

NetSolve shall have no obligation with respect to any such claim of infringement
based upon NEC's modification of any Licensed Products or other Licensed
Products or their combination, operation or use with apparatus, data or computer
programs not furnished by NetSolve. NEC will indemnify, hold harmless and defend
NetSolve at its own expense against any claim of patent, copyright, trademark or
trade secret infringement based on (A) algorithms or software code incorporated
in the Licensed Products at NEC's request; and (B) NEC's use of the Licensed
Products with other systems, software, algorithms, or similar items.

     c)   Limitation: Notwithstanding the provision of Subsection l3b above or
          ----------
          any other provision to the contrary, NetSolve assumes no liability for
          (i) any infringement in connection with any assembly, circuit,
          combination, method or process in which any Licensed Product is used
          when such infringement would not arise from the Licensed Products
          standing alone; (ii) any trademark, service mark or trade name
          infringement involving any marking or branding not applied by NetSolve
          or involving the modification or servicing of the Licensed Products,
          or any part thereof, unless such modification or servicing was done by
          NetSolve and not at the request of NEC; (iii) modifications made to
          Licensed Products at NEC's request.

     d)   Entire Liability: The foregoing provisions of this Section 13 state
          ----------------
          the entire liability and obligations of NetSolve and the exclusive
          remedy of NEC and its customers with respect to any alleged
          infringement of patents, copyrights, trademarks, trade secrets or
          other intellectual property rights by the Licensed Products or any
          part thereof.

          being a "Prohibited Payment"). NEC hereby represents and warrants
          that, in connection with the performance of this Agreement, NEC and
          its officers, directors, employees, and agents, have not and will not

          effect in the interpretation of this Agreement or in determination of
          the interests of either party hereto. Furthermore, the parties agree
          that all correspondence, notices, orders, claims, suits and other

           completely pay, perform and discharge when due all Excluded
           Obligations.

     3.    Acquisition Price and Certain Additional Payments
           -------------------------------------------------

     3.1.  Acquisition Price. Upon Closing (as that term is defined in Section
           -----------------
           8.3 below), Buyer will make a payment to Seller equal to * percent
           (*%) of the Aggregate Remaining Term Value (specified on Schedule 1.1
           hereto) of the Acquired Contracts ("Acquisition Price"). The parties
                                               -----------------
           understand and agree that the Aggregate Remaining Term Value shall
           not include any contracts pursuant to which Buyer performs services
           as a subcontractor of Seller under Section 7.7.

     3.2.  Additional Continuing Payments. In addition to the Acquisition Price,
           ------------------------------
           Buyer agrees to pay Seller the continuing payments described below.

           (a) Commencing as of the Service Date and continuing until such time
               as Buyer has collected aggregate fees from customers under the
               Acquired Contracts equal to the Aggregate Remaining Term Value of
               all Acquired Contracts, Buyer will, on or before the twentieth
               (20th) day of each month, pay Seller an amount equal to a certain
               percentage of the fees (specified on Schedule 1.1 hereto)
               collected by Buyer during the previous month for services
               previously rendered by Buyer under the Acquired Contracts. The
               first payment of fees by Buyer to Seller for each Acquired
               Contract under this subsection will be prorated so that Seller
               shall receive the pro rata portion allocable to that part of the
               first month that follows the Service Date. After Buyer has
               collected fees from the customers under the Acquired Contracts
               equal to the Aggregate Remaining Term Value of all Acquired
               Contracts, the additional monthly payment provided for in this
               paragraph shall be increased to * percent (*%) of the fees
               collected by Buyer during the previous month for services

               sold by Buyer to customers under the Acquired Contracts and
               booked by Buyer after March 31, 2002, Buyer will, on or before
               the twentieth (20th) day of each month, pay Seller * percent (*%)
               of the fees collected by Buyer during the previous month relating
               to such New Business. "New Business" shall mean additional
                                      ------------
               recurring network management services, including such services
               for new locations, not being purchased by the customer under the
               Acquired Contract at the time of Closing. In the event that the
               aggregate fees collected by Buyer under the Acquired Contracts
               for network management services are, at any point in time and on
               an ongoing basis, less than the amount of the anticipated fees
               that Buyer should have collected based on the Aggregate Remaining
               Term Value of the Acquired Contracts, due to early terminations
               not caused by Buyer performance or quality issues, Buyer will
               have the right to reduce the percentage applicable to New
               Business to * percent (*%).

           (c) The monthly payments provided for under Sections 3.2(a) and
               3.2(b) shall continue through the later of March 31, 2004, or the
               expiration or termination of the original term of the Acquired
               Contract. All Acquired Contracts, whether in their initial term
               or a renewal term, will be included in calculating such monthly
               payments for the period commencing as of the Service Date and
               ending March 31, 2004. For the period beginning April 1, 2004,
               only Acquired Contracts that are in their initial term will be
               included in the calculation of the payments.

           (d) For each customer of Seller (excluding customers under the
               Acquired Contracts) which Seller refers to Buyer in writing and
               with which Buyer enters into a contract for the sale of Buyer's
               network management services (each, a "New Customer Contract"),
                                                     ---------------------
               Buyer will, on or before the twentieth (20th) day of each month,
               pay Seller an amount equal to * percent (*%) of the fees
               collected by Buyer during the previous month for services
               previously rendered by Buyer under each New Customer Contract.
               With respect to each New Customer Contract, the payments will
               continue for the longer of the initial term of such New Customer
               Contract or two (2) years from the date of the execution of such
               New Customer Contract, unless the New Customer Contract is
               terminated prior to such time, in which case Buyer's payments
               hereunder with respect to such New Customer Contract shall cease
               upon termination.

           (e) Notwithstanding any other provision of this Agreement, the
               parties understand and agree that the additional monthly payments
               provided for in this Section 3.2 shall be calculated solely on
               the basis of fees actually collected by Buyer for recurring
               network management services. In furtherance of this, the
               calculation of such additional monthly payments shall not include
               amounts received by Buyer for one-time implementation

               structures the pricing under a particular contract.

     3.3.  Audit.  Buyer shall keep true and accurate records relating to the
           -----
           Acquired Contracts in accordance with reasonable business practices.
           Buyer shall make such records available for audit by Seller semi-
           annually upon thirty (30) days prior written notice, during regular
           business hours at Buyer's principal place of business, provided that
           no such audit shall unreasonably interfere with Buyer's business.

           ------------------------------------------
           warranties made by Buyer and Seller are made as of the Closing and
           not on a continuous basis. All representations and warranties made by
           or on behalf of Seller in this Agreement shall be deemed to have been
           relied upon by Buyer (notwithstanding any investigation by Buyer).

     6.3.  Notice of Claims. An indemnified party shall give prompt written
           ----------------
           notice to the indemnifying party of any claim against the indemnified
           party which might give rise to a claim by the indemnified party
           against the indemnifying party under the indemnification provisions
           contained herein, stating the nature and basis of the claim and the
           actual or estimated amount thereof; provided, however, that failure
                                               -----------------
           to give such notice will not effect the obligation of the
           indemnifying party to provide indemnification in accordance with the
           terms of Section 6.1 unless, and only to the extent that, the
           indemnifying party is actually prejudiced thereby. In the event that
           any action, suit or proceeding is brought against any indemnified
           party with respect to which the indemnifying party may have liability
           under the indemnification provisions contained herein, the
           indemnifying party shall, upon written acknowledgement by the
           indemnifying party that such action, suit or proceeding is an
           indemnifiable loss pursuant to Section 6.1, have the right, at the
           cost and expense of the indemnifying party, to defend such action in
           the name and on behalf of the indemnified party (using counsel
           reasonably satisfactory to the indemnified party), and, in connection
           with any such action, the indemnified party and indemnifying party
           agree to render to each other such assistance as may reasonably be
           required in order to ensure proper and adequate defense of such

                                       10
<PAGE>

           action; provided, however, that an indemnified party shall have the
                   -----------------
           right to retain its own counsel, with fees and expenses paid by the
           indemnifying party, if representation of such indemnified party by
           counsel retained by the indemnifying party would be inappropriate
           because of an actual conflict of interest between such indemnified
           party and the indemnifying party in the particular matter at hand. If
           the indemnifying party shall fail to defend such action, suit or
           proceeding, then the indemnified party shall have the right to defend
           such action without prejudice to its rights to indemnification under
           Section 6.1 and, in connection therewith, the indemnified party and
           the indemnifying party agree to render to each other such assistance
           as may reasonably be required in an effort to provide for the
           appropriate defense of such action. Neither the indemnified party nor
           the indemnifying party shall make any settlement of any claim which
           might give rise to liability of the indemnifying party under the
           indemnification provisions contained herein without the written
           consent of each party, which consent shall not be unreasonably
           withheld, delayed or conditioned.

     7.    Additional Agreements
           ---------------------

     7.1.  Operations. Buyer intends to transfer network operations for the
           ----------
           Acquired Contracts from Seller's center in Wood Dale, Illinois to
           Buyer's center in Austin, Texas as soon as reasonably practical
           following the assignment of the Acquired Contracts to Buyer
           hereunder. Seller understands, however, that it will be required to
           retain and continue to operate its network operations center for the
           Acquired Contracts for a mutually agreeable period of time beyond
           Closing. The parties agree, however, that if Seller is required to
           continue to operate its network operations center beyond May 15, 2001
           in order to support any Acquired Contracts (excluding Acquired
           Contracts assigned to Buyer after April 15, 2001, or Acquired
           Contracts for which pertinent information necessary to transition the
           Acquired Contracts is not provided to Buyer as provided for in the
           last sentence of this Section 7.1 and contracts for which Buyer acts
           as a subcontractor), Buyer will reimburse Seller for all reasonable
           operational costs associated with the continued operation of Seller's
           network operations center so long as such continued operations are
           solely in connection with such Acquired Contracts. In no event will
           the reimbursement amount for any given month exceed the amount
           collected as fees for the Business under the Acquired Contracts for
           that month. In order to facilitate a smooth and timely transition of
           the Acquired Contracts to Buyer, Seller will upon Closing, and
           continuing weekly thereafter, provide Buyer with all requisite site
           implementation information for all of the Acquired Contracts in
           increments of a minimum of 1,000 sites per week.

     7.2.  Billing and Apportionment.  In order to effectuate an orderly billing
           -------------------------
           transition to Buyer, Seller shall continue to bill for services
           rendered by Buyer under the Acquired Contracts during the period
           commencing as of the Closing and ending June 30, 2001. After the
           invoice for the month of June is mailed out by Seller, Buyer shall be
           responsible for billing customers directly under all Acquired

                                       11
<PAGE>

           Contracts. Until May 31, 2001, Buyer will provide Seller with any
           changes to the standard monthly recurring billing information for
           services rendered by Buyer for the previous month under the Acquired
           Contracts fifteen (15) days prior to the date Seller sends its
           invoice to customers. On a monthly basis, Seller shall remit to Buyer
           the amount of any payment received from customers in the prior month
           attributable to the Acquired Contracts following the Service Date for
           the Acquired Contracts and will retain any amounts due to Seller
           pursuant to Section 3.2 hereof for Acquired Contracts fully
           transitioned to Buyer.

     7.3.  Transfer of Business.  For the period of time commencing with the
           --------------------
           Effective Date and ending March 31, 2004, Seller shall not, and shall
           cause its employees, agents, representatives, affiliates, officers
           and directors not to induce, incent, solicit or encourage, in any
           manner, any customer of Seller under an Acquired Contract to transfer
           to, or seek network management services as described in the Acquired
           Contracts from, a provider other than Buyer.

     7.4.  Confidentiality. Seller and Buyer shall abide by the terms of the
           ---------------
           non-disclosure provisions provided for in the Acquired Contracts.

     7.5.  Non-Compete. In consideration of the Acquisition Price and the
           -----------
           continuing payments provided for herein, Seller agrees that for a
           period of three (3) years from the Effective Date, Seller shall not
           directly or through any affiliate sell, as a stand-alone service, to
           customers under the Acquired Contracts remote monitoring or network
           management services similar in scope and function to the services
           described in the Acquired Contracts.

     7.6.  Employees. Buyer shall be permitted to discuss potential employment
           ---------
           arrangements with those employees of Seller identified on Schedule
           7.6. Buyer and Seller shall mutually agree to the employment start
           date for any such employee hired by Buyer if such start date is prior
           to May 15, 2001.

     7.7.  Subcontractor Agreement.  Seller shall use all reasonable efforts to
           -----------------------
           obtain any consents necessary to assign or otherwise transfer all the
           Seller's contracts in the Business to Buyer. In the event that any
           consent required with respect to a contract in the Business cannot be
           obtained, Seller may at its option and if permitted under the terms
           of each such contract subcontract all of its obligations relating to
           the Business under such contract to Buyer. In such event, Buyer and
           Seller shall enter into a Schedule under the Subcontractor Agreement
           attached hereto as Exhibit A (the "Subcontractor Agreement") covering
           each such contract subcontracted to Buyer. Seller will retain the
           billing obligation for all contracts subcontracted to Buyer.

     7.8.  Set-Off.  Buyer shall have the right to set-off the following amounts
           -------
           against the payments due Seller pursuant to Sections 3.2(a), (b) and
           (d):

                                       12
<PAGE>

               (i)    A pro rata portion of the Acquisition Price for a
                      particular Acquired Contract if: (i) the customer
                      terminates such Acquired Contract prior to the expiration
                      of the term stated on Schedule 1.1 for such contract; (ii)
                      such early termination right is provided for in the
                      Acquired Contract; and (iii) such termination is not
                      caused by Buyer performance or quality issues. The pro
                      rata portion of the Acquisition Price to be set-off shall
                      be * percent (*%) of the difference between the Aggregate
                      Remaining Term Value of the Acquired Contract as listed on
                      Schedule 1.1 and the actual aggregate remaining term value
                      of the Acquired Contract based on the early termination
                      date;

               (ii)   The amount of any credits, penalties, fee reductions or
                      reimbursements which are provided for in an Acquired
                      Contract and are exercised by a customer or otherwise
                      become applicable following the Service Date for such
                      Acquired Contract;

               (iii)  A pro rata portion of the Acquisition Price for a
                      particular Acquired Contract if: (i) the term of the
                      Acquired Contract actually expires earlier than the term
                      date stated on Schedule 1.1 for such Acquired Contract;
                      and (ii) the customer under the Acquired Contract does not
                      renew or extend such contract. The pro rata portion of the
                      Acquisition Price to be set-off shall be calculated by:
                      (i) multiplying the Acquisition Price of such Acquired
                      Contract by the ratio of the number of days in the actual
                      term of the Acquired Contract and the number of days in
                      the term stated on Schedule 1.1; and then (ii) subtracting
                      such amount from the Acquisition Price. If, however, a
                      set-off against the payments due Seller pursuant to
                      Sections 3(a), (b) and (d) is not sufficient to reimburse
                      Buyer the pro rata portion of the Acquisition Price due
                      Buyer pursuant to this subsection and such pro rata
                      portion of the Acquisition Price is greater than or equal
                      to * percent (*%) of the difference between the actual
                      remaining term value of the Acquired Contract based on the
                      actual term and the Aggregate Remaining Term Value of such
                      Acquired Contract as listed on Schedule 1.1, Seller shall
                      reimburse Buyer the pro rata portion of the Acquisition
                      Price within thirty (30) days of its receipt of written
                      notice of such amount; and

               (iv)   A pro rata portion of the Acquisition Price for a
                      particular Acquired Contract if the actual price per
                      device for an Acquired Contract is actually lower than the
                      price per device for such Acquired Contract listed on
                      Schedule 1.1. The pro rata portion of the Acquisition
                      Price to be set-off shall be * percent (*%) of the
                      difference between the Aggregate Remaining Term Value of

                      the Acquired Contract as listed on Schedule 1.1 and the
                      actual aggregate remaining term value of the Acquired
                      Contract based on the actual price per device amount. If,
                      however, a set-off against the payments due Seller
                      pursuant to Sections 3(a), (b) and (d) is not sufficient
                      to reimburse Buyer the pro rata portion of the Acquisition
                      Price due Buyer pursuant to this subsection and such pro
                      rata portion of the Acquisition Price is greater than or
                      equal to * percent (*%) of the difference between the
                      actual remaining term value of the Acquired Contract based
                      on the actual price per device and the Aggregate Remaining
                      Term Value of such Acquired Contract as listed on Schedule
                      1.1, Seller shall reimburse Buyer the pro rata portion of
                      the Acquisition Price within thirty (30) days of its
                      receipt of written notice of such amount.

     8.    Closing.
           -------

     8.1.  Initial Closing. The closing of the transactions contemplated by this
           ---------------
           Agreement shall take place by facsimile or at the offices of
           Comdisco, Inc. in Rosemont, Illinois on or before March 15, 2001
           unless extended by both parties. The date on which such closing
           actually takes place is herein referred to as the "Initial Closing".
                                                              ---------------
           Any subsequent closing will occur as provided for in Section 8.2.

     8.2.  Subsequent Closings.  For contracts related to the Business for which
           -------------------
           Seller was unable to obtain a necessary consent to assignment prior
           to the Initial Closing, there may be additional closings as such
           consents to assignment are obtained (each a "Subsequent Closing");
                                                        ------------------
           provided, however, that no such Subsequent Closing shall occur later
           than April 16, 2001, unless mutually extended by Buyer and Seller.
           Anything in this Agreement to the contrary notwithstanding, the
           network diagrams, ARS database images, escalation procedures,
           performance reports and contact lists for the contracts to be added
           as Acquired Contracts pursuant to Subsequent Closings must be
           provided to Buyer prior to April 16, 2001, unless mutually extended
           by Buyer and Seller.

     8.3.  Closing Procedures. Each date on which either the Initial Closing or
           ------------------
           a Subsequent Closing takes place shall be deemed a "Closing". Each
           Closing will result in the contract for which the necessary consent
           has been obtained becoming an Acquired Contract for all purposes
           hereof as of the Effective Date for the Initial Closing and the date
           that the customer under the Acquired Contract executes the necessary
           consent to assignment for Subsequent Closings. Upon each Subsequent
           Closing, Schedule 1.1 shall be modified and updated to reflect each
           such contract as an Acquired Contract. Upon each Closing, Buyer shall
           pay Seller an amount equal to the Acquisition Price for each Acquired
           Contract added to Schedule 1.1 for that Closing. All terms and
           conditions of this Agreement, including the representations and
           warranties of each party, will apply to each

<PAGE>

           Acquired Contract and will be updated and renewed as of each
           Subsequent Closing with respect to the applicable newly added
           Acquired Contract.

     8.4.  Post-Closing Obligations. Following each Closing, Buyer and Seller
           ------------------------
           shall execute and deliver such documents, and take such action as
           shall be reasonably requested by the other party to carry out the
           transactions herein contemplated.

     9.    General.
           -------

     9.1.  Expenses. Except as expressly provided for in Section 7.1, all
           --------
           expenses of the preparation, execution and consummation of this
           Agreement and of the transactions contemplated hereby including,
           without limitation, attorneys', accountants' and outside advisors'
           fees and disbursements, shall be borne by the party incurring such
           expenses.

     9.2.  Entire Agreement. This Agreement contains the entire understanding of
           ----------------
           the parties and supersedes all prior agreements and understandings
           relating to the subject matter hereof, including, without limitation,
           the letter of intent dated February 8, 2001, among the parties
           hereto, and shall not be amended or terminated except by a written
           instrument hereafter signed by all of the parties hereto. The
           Schedules to this Agreement are to be considered a part of this
           Agreement for all purposes.

     9.3.  Assignment. None of the parties hereto may assign its rights or
           ----------
           delegate its obligations under this Agreement without the prior
           written consent of the other party.

     9.4.  Further Action.  Each of the parties hereto shall use all reasonable
           --------------
           efforts to do, or cause to be done, all things necessary, proper or
           advisable under applicable law to carry out the provisions of this
           Agreement and shall execute and deliver such documents and other
           papers as may be required to carry out the provisions of this
           Agreement.

     9.5.  Notices. All notices will be in writing and will be sent by certified
           -------
           or registered United States mail, postage prepaid and return receipt
           requested, or via a prepaid nationally recognized overnight courier
           or facsimile transmission. Notices will be addressed to the party for
           which it is intended at the address in the first paragraph of this
           Agreement or to such other address as either party shall from time to
           time indicate in writing. Notices will be effective upon receipt. A
           facsimile counterpart of any notice may be delivered to the parties
           and each party adopts its signature on the facsimile as its original
           signature and agrees that the facsimile will have the same effect as
           if the document had been signed and delivered by mail or in person.

                                       15

     9.6.  Specific Performance. The parties agree that due to the unique
           --------------------
           subject matter of this transaction, monetary damages will be
           insufficient to compensate the non-breaching party in the event of a
           breach of any part of this Agreement. Accordingly, the parties agree
           that the non-breaching party shall be entitled (without prejudice to
           any other right or remedy to which it may be entitled) to an
           appropriate decree of specific performance, or an injunction
           restraining any violation of this Agreement or other equitable
           remedies to enforce this Agreement (without establishing the
           likelihood of irreparable injury or posting bond or other security),
           and the breaching party waives in any action or proceeding brought to
           enforce this Agreement the defense that there exists an adequate
           remedy at law.

     9.7.  Severability.  If any one or more of the provisions contained in this
           ------------
           Agreement or any document executed in connection herewith shall be
           invalid, illegal or unenforceable in any respect under any applicable
           law, the validity, legality and enforceability of the remaining
           provisions contained herein shall not (to the full extent permitted
           by law) in any way be affected or impaired.
