NEC, HNSX and Cray are sometimes hereinafter collectively referred to as the
"parties."

                                    RECITALS

               A.     NEC and Cray are parties to a Distribution Agreement,
dated as of February 28, 2001 (the "Distribution Agreement"), pursuant to which
parties have agreed that Cray shall become the distributor of certain products
of NEC upon the terms and subject to the conditions set forth therein.

               B.     Cray is interested in obtaining from NEC and/or HNSX
certain services listed and described in Schedule A attached hereto commencing
from the Effective Date.

               NOW, THEREFORE, the parties, in consideration of the premises and
the mutual covenants and agreements contained herein, and intending to become
legally bound, hereby agree as follows:

                                    SECTION 1
                    AGREEMENT TO PROVIDE AND OBTAIN SERVICES

               1.1    Definitions. Except as otherwise defined in this
Agreement, all capitalized terms shall have the meanings assigned to them in the
Distribution Agreement.

               1.2    Scope of Services.

                      (a)    NEC or HNSX shall provide to Cray the services
described on Schedule A (the "Services") for the period set forth on Schedule A
for each such Service, in accordance with the terms, limitations and conditions
set forth herein and on Schedule A.

                      (b)    If Cray identifies any additional Service it
reasonably requires from NEC in order to perform the Distribution Agreement,
Cray may request such additional Service and Schedule A will be amended to
reflect any agreed additional service; provided, that this Section 1.2(b) shall
not require NEC to provide any additional Services without NEC's express written
consent, which NEC may withhold in its sole discretion.

<PAGE>   2

                      (c)    Any amendment, supplement, variation, alteration or
modification to any Service as described on Schedule A shall be made in writing
and duly executed by each party.

               1.3    Access. Each party shall take all actions and make
available on a timely basis all information and materials reasonably required
for the other parties to perform their obligations hereunder. No party shall be
liable for any claims, errors or omissions resulting from untimely or incorrect
information provided by another party. Each party shall give the other parties
access to its premises during regular business hours and at such other times as
are reasonably required, after prior consent has been obtained, to the extent
reasonably necessary for the other parties to perform their obligations
hereunder.

                                    SECTION 2
                    SERVICES; PAYMENT; INDEPENDENT CONTRACTOR

               2.1    Services to be Provided.

                      (a)    Unless otherwise agreed in writing by the parties,
each party shall use commercially reasonable efforts to perform its obligations
hereunder. Notwithstanding anything to the contrary contained herein, no party
shall be in default of its obligations hereunder to the extent the inability to
perform such obligations arises out of the another party's failure to perform in
a timely manner such tasks as are required to be performed to enable the
performing party to perform such obligations.

                      (b)    NEC and HNSX shall have the right to cease
temporarily for maintenance purposes the operation of the equipment or
facilities providing any Service whenever they determine in their reasonable and
good faith judgment such action is necessary. In the event such maintenance is
required, Cray shall be reasonably notified of such maintenance (which notice
may be given during or after any emergency maintenance). Notwithstanding the
above, NEC or HNSX shall give Cray as much advance notice of any shutdown as is
reasonably practicable. Where written notice is not feasible, oral notice may be
given. NEC and HNSX shall be relieved of their respective obligations to provide
any Service during the period that the necessary equipment or facilities are
shut down; provided, that NEC and HNSX shall use commercially reasonable efforts
to restart such equipment or reopen such facilities as promptly as practicable.

                      (c)    HNSX shall be excused from performance of the
Services to the extent that its ability to perform the Services is reduced or
eliminated by loss of personnel to Cray, and HNSX shall have no obligation to
hire any replacements for departing personnel.

               2.2    Payment. Invoices for Services shall be due 30 days after
receipt by the payor. All amounts due on invoices shall be paid in United States
Dollars by wire transfer to an account specified by the payee. Invoiced amounts
not paid when due shall be subject to late charges for each month and portion
thereof that the invoice is overdue, with such late charges


                                        2

calculated at the lesser of (i) 18% per annum and (ii) the maximum rate allowed
by applicable law.

               2.3    Independent Contractor. All Services required of NEC and
HNSX shall be performed by them as independent contractors, and employees of NEC
and HNSX providing Services shall at all times be under NEC's and HNSX's sole
direction and control. Neither NEC, HNSX nor any other person or entity
performing any Services hereunder on behalf of NEC or HNSX shall be deemed for
any purpose to be the agent, servant, employee or representative of Cray in the
performance of this Agreement. Nothing in this Agreement shall be construed to
mean that NEC or HNSX is a partner or a joint venturer of Cray. The relationship
under this Agreement of NEC and HNSX on the one hand and Cray on the other hand
with respect to the Services shall be that of an independent contractor.

                                    SECTION 3
                                      TERM

               The term of this Agreement shall be conditioned upon and commence
upon on the date (the "Effective Date") of the closing under the Stock Purchase
Agreement and shall terminate upon the earlier of (i) the expiration of the
Distribution Agreement, and (ii) any termination pursuant to Section 5.2 or 5.3;
provided that with respect to each Service listed in Schedule A, this Agreement
shall terminate as set forth in Section 5.1.

                                    SECTION 4
                                   LIABILITIES

               4.1    Consequential and Other Damages. Neither NEC nor HNSX
shall be liable for, and Cray expressly waives any right to recover, whether in
contract, in tort (including, but not limited to, negligence and strict
liability) or otherwise, any punitive, exemplary, special, indirect, incidental
or consequential damages whatsoever, which in any way arise out of, relate to,
or are a consequence of, NEC's or HNSX's performance or nonperformance
hereunder, or the provision of or failure to provide any Service hereunder,
including, but not limited to, loss of profits, business interruptions and
claims of customers.

               4.2    Limitation of Liability. In any event, the liability of
any NEC Indemnitee (as defined in Section 4.4) which liability shall be several

herewith, including, but not limited to, the performance or breach hereof, or

               4.3    Obligation to Reperform. In the event that Cray becomes
aware of any material breach of this Agreement by NEC or HNSX with respect to
any error or defect in the provision of any Service, and Cray notifies NEC and
HNSX of said breach, NEC or HNSX (as applicable) shall promptly make
commercially reasonable efforts to correct such error or defect.

               4.4    Indemnity. Cray shall indemnify and hold harmless NEC and

liabilities, losses, damages, costs and expenses (collectively, "Losses")
arising from or relating to the presence of Cray employees, agents or
subcontractors on NEC's or HNSX's premises; provided, however, that no NEC
Indemnitee shall be entitled to indemnification hereunder to the extent its
claim for indemnification shall be finally adjudged to be attributable to its
gross negligence, bad faith or willful misconduct, as may be finally determined
by arbitration pursuant to Section 6.13. Subject to Sections 4.1 and 4.2, NEC
shall indemnify and hold harmless Cray, its subsidiaries, affiliates, successors
and assigns, directors, officers, shareholders, agents and employees

negligence, bad faith or willful misconduct, as may be finally determined by
arbitration pursuant to Section 6.13.

               4.5    Notification and Procedures. In connection with any
indemnity hereunder, the indemnified party shall: (i) promptly notify the
indemnifying party of any claim or proceeding, or threatened claim or
proceeding; (ii) permit the indemnifying party to take full control of such
claim or proceeding; (iii) cooperate in the investigation and defense of such
claim or proceeding; (iv) not compromise or otherwise settle such claim or
proceeding without the prior written consent of the indemnifying party, which
consent shall not be unreasonably withheld, conditioned or delayed; and (v) take
all reasonable steps to mitigate any loss or liability in respect of any such
claim or proceeding. In any action in which the indemnifying party assumes
control, the indemnifying party shall not enter into any settlement without the
prior written consent of the indemnified party, which shall not be unreasonably
withheld, conditioned or delayed.

                                    SECTION 5

Distribution Agreement, NEC shall provide Cray with sales and marketing
assistance on the terms and conditions set forth below:

                      1.1    Competitiveness. As part of NEC's formal high

                      1.2    Benchmark System Availability. Cray will purchase
from NEC a SX-5X to be used for benchmarking purposes. If Cray requires
benchmarking capacity on a larger system, NEC will, subject to advance
scheduling and task effort specification, make available a NEC system resource
and support person either remotely or on location. In the event that Cray needs
to benchmark a SX-5X prior to the date on which NEC delivers Cray's SX-5X, NEC
shall make available (subject to other NEC commitments) a SX-5X system installed
in Japan for the performance of benchmarks by Cray. The parties will discuss in
good faith and mutually agree on the scheduling of these benchmarks based on
overall system usage commitments, effort definition and support resource
availability. The cost of system usage, telecommunications, courier service and
travel, lodging and per diem for Cray personnel incurred in connection with the
activities conducted under this Section 1.2 will be borne by Cray.

                      1.3    Prospect/Customer Visits to Japan. NEC will
accommodate visits by Cray prospects and customers to NEC facilities on a
scheduled, best efforts basis, subject to availability of NEC personnel. Travel,
per diem and lodging costs will be borne by Cray.

                      1.4    Promotional Activity Coordination. At least yearly,
NEC will provide Cray with its promotional agenda and schedule.

                      1.5    Marketing and Promotional Literature. NEC will
provide to Cray without charge a reasonable number of copies of marketing and
promotional brochures, product briefs, product descriptions, marketing aids and
the like relating to the Products at such time and in such languages as NEC
makes them generally available to its direct high performance computing system
sales and marketing organizations throughout the world.

                      1.5.1. Cray may use the marketing and promotional
literature to prepare Cray-specific marketing and promotional literature.

                      1.5.2. Cray shall take all appropriate legal measures to

                      1.5.3. If Cray adds to or otherwise modifies the marketing
and promotion literature, Cray should provide to NEC a reasonable number of
copies of the modified or added literature.

               2.     Post-SX-5X Sales and Marketing Support. In the event that
NEC introduces a successor supercomputer system to the SX-5X, the parties
anticipate that they will engage in sales and marketing support activities
similar to the type contemplated by this Agreement with respect to such system
upon commercially reasonable terms to be mutually agreed.
