"Statement of Work" and shall be signed by (and may only be modified in writing
and signed by) an authorized representative of Customer and EMC. Professional
Services shall be provided by EMC in accordance with the agreed Statement of
Work. Both parties anticipate that the Professional Services will be performed
in several phases, where the results of a preliminary phase will likely impact
the scope of services provided during a subsequent phase.

B. STAFF RESPONSIBILITY AND REPLACEMENT: EMC shall assume sole responsibility
for the supervision of its consultants assigned to perform the Professional
Services. If one of EMC's consultants resigns or is unable to complete his or
her assigned portion of the Professional Services for any reason, EMC shall
replace such consultant with a consultant of substantially equivalent
qualifications under the same terms and conditions as are set forth in the
Statement of Work.

C. ADJUSTMENTS TO MILESTONE COMPLETION DATES: If Customer is unable to provide
information, support or assistance reasonably requested by EMC to perform the
Professional Services in a timely manner as described in the applicable
Statement of Work, then the completion date(s) for milestones identified in such
Statement of Work shall be extended by the amount of time equal to the delay in
Customer's response, as reasonably determined by EMC. Similarly, if Customer
requests in writing the replacement of one of EMC's consultants, then the
completion date(s) for milestones identified in such Statement of Work shall be
extended by the amount of time required by EMC to replace that consultant (not
to exceed 30 days) and the amount of time required to acclimate the replacement
consultant to the Professional Services to be performed pursuant to that
Statement of Work, as reasonably determined by EMC.

6. GENERAL TERMS

A. ORDERS: Any Order must refer to the Agreement Number and must include
information necessary to complete the associated transaction.

B. SOFTWARE:

(1). EMC grants to Customer a non-exclusive, non-transferable license to use the
Software solely in conjunction with the Designated EMC System or Host CPU, as
applicable, for which the Software was licensed.

(2). Customer shall not, without EMC's prior written consent, provide, disclose
or otherwise make available Software in any form to any person other than
Customer's employees, independent contractors or consultants, who shall use the
Software solely for Customer's internal business purposes in a manner consistent
with this Agreement. Customer shall be fully responsible to EMC for the actions
of its employees, independent contractors and consultants.

(3). Customer may make one copy of the Software for back-up and archival
purposes for use only in the case of a malfunction of Software, EMC Designated
System or Host CPU, as applicable.

(4). Customer may, only after written notice to EMC, change the location of a
Designated EMC System or Host CPU upon which the licensed Software is used to a
replacement location. If Customer moves the Software to another Designated EMC
System or Host CPU which has a different model number than the originally
Designated EMC System or Host CPU, Customer agrees to pay, if applicable, an
upgrade fee based on EMC's then-current

                                    Page 55
<PAGE>   56

price and upgrade policy and, at the next support anniversary date, agrees to
pay applicable fees based upon the replacement model number.

(5). If Customer is granted a license to use Software in conjunction with a
Statement of Work (a "Project License"), Customer shall have a non-transferable
right to use the Software only for the purpose of conducting a specific project
under such Statement of Work. The Project License term shall be for one (1) year
or the completion of the project, whichever occurs first.

(6). Customer shall not use the Software on any device other than the Designated
EMC System or Host CPU, as applicable, except that the Enterprise Storage
Software may be temporarily transferred to a replacement Designated EMC System
or Host CPU, as applicable (and deleted from the original Designated EMC System

malfunction or initiation of a disaster recovery program or is otherwise not
able to use the Enterprise Storage Software.

(7). Ownership: No title to, or ownership of, the Software is transferred to
Customer, and any references to "sale" or "purchase" of the Products, with
respect to the Software, shall be deemed to mean "license on the terms contained
in this Agreement." Customer shall reproduce and include EMC's copyright and
other proprietary notices on and in any copies, including but not limited to
partial, physical or electronic copies of the Software. Neither Customer nor any
of its agents, independent contractors or consultants shall modify, enhance,
supplement, create derivative works from, reverse assemble, reverse engineer,
reverse compile or otherwise reduce to human readable form the Software without
EMC's prior written consent. If Customer requires access to the source code of
the Software in order to achieve interoperability of the Software with other
software in the European Union or Norway, Customer shall provide EMC with
written notice. EMC can then decide either: (i) to perform the work in order to
achieve such interoperability and charge EMC's then-current rates for such work
to Customer; or (ii) to permit Customer to reverse engineer parts of the
Software in order to obtain such source code, but only to the extent necessary
to achieve such interoperability. Customer shall promptly report to EMC any
violation of this clause and shall take such further steps as may be reasonably
requested by EMC to remedy any such violation and to prevent future violations.

(8). Secondary Purchaser: Customer's right to use the Software may not be
assigned, sublicensed or otherwise transferred; provided however, that if

license the Core Software and to render Equipment and Core Software Product
Maintenance to any bona fide end user (hereinafter "Secondary Purchaser") to
whom Customer has transferred the Designated EMC System pursuant to EMC's
then-current standard terms and conditions, so long as such Secondary Purchaser
is not deemed, in EMC's reasonable discretion, to be a competitor of EMC's.
Whenever the Core Software is licensed to a Secondary Purchaser in accordance
with this Paragraph, EMC shall offer to provide de-installation services for
Customer and re-installation and certification for Equipment and Core Software
Product Maintenance for the Secondary Purchaser at EMC's then-current applicable

Equipment and/or Software.

H. PRODUCT CHANGES: EMC reserves the right, at its expense, to make changes to
the Products: (a) upon reasonable notice to Customer, when such changes do not
adversely affect interchangeability or performance of the Products; (b) when EMC
believes changes are required for purposes of safety or reliability; or (c) when
EMC is required by law to do so. Customer shall give EMC reasonable access to
the Products for such purpose; failure to permit EMC to effect these changes
shall allow EMC to terminate Product Maintenance for all affected Products
without liability and without refunding to Customer any fees already paid for
such Product Maintenance.

I. DOCUMENTATION: EMC will provide Customer with one (1) then-current end-user
manual set with each article of Equipment and Software shipped under this
Agreement. Additional manuals or updates may be obtained from EMC. Customer

only at the Designated Site for its own internal use. Customer shall have no
right (i) to permit any third party to access or use such documentation, or (ii)
to copy or create derivative works of such documentation, whether for Customer's
internal use or otherwise.

J. PATENT AND COPYRIGHT

(1). If Customer notifies EMC promptly in writing of any action (and all prior
related claims) brought against Customer alleging that Customer's sale, use or
other disposition of any Equipment, Customer's use of any Software or its
receipt of any Service infringes a valid United States patent or copyright, EMC
will defend that action at its expense and will pay the costs and damages
awarded against Customer in the action, provided (i) that EMC shall have sole
control of the defense of any such action and all negotiations for its
settlement or compromise and (ii) Customer provides all reasonable assistance
requested by EMC. If a permanent injunction is obtained in such action against
Customer's use or receipt of such Product or if in EMC's opinion such Product is
likely to become the subject of a permanent injunction, EMC will at its option
and expense either procure for Customer the right to continue using or receiving
such Product, replace or modify such Product so that it becomes non-infringing
or pay Customer a refund based on a straight line depreciation of the price of
such Equipment and/or Software over five (5) years upon return of the Equipment
and/or Software to EMC or refund the unused amounts paid to EMC for discontinued
Product Maintenance, as the case may be.

(2). EMC shall have no liability to Customer if the alleged infringement is
based on (i) use, sale or receipt of any of the Products in combination with
other equipment, software or services not provided by EMC; (ii) use of any of
the Products in a manner or for a purpose for which they were not designed;
(iii) use of the Software, when use of a Software Release which EMC has made
commercially available would have avoided such infringement; (iv) any
modification to any of the Products not made by EMC, or any modifications to any
of the Products made by EMC pursuant to Customer's specific instructions; or (v)
any intellectual property right owned or licensed by Customer or any of its
Affiliates.

(3). THIS PATENT AND COPYRIGHT SECTION STATES EMC'S ENTIRE LIABILITY WITH
RESPECT TO ALLEGED INFRINGEMENTS OF PATENTS, COPYRIGHTS AND OTHER INTELLECTUAL
PROPERTY RIGHTS BY THE PRODUCTS OR ANY PART OF THEM OR BY THEIR OPERATION, USE
OR RECEIPT.
