the applicable members of the Parent Group to grant, Sub and the applicable
members of the Sub Group a license (the "Space License") to use and occupy the
office space at the Leased Premises as indicated on Schedule B attached hereto
                                                    ----------
(collectively, the "Space"), including the right to utilize all rest rooms,
cafeteria and fitness center facilities, outdoor facilities generally available
to employees of Parent and/or the applicable member of the Parent Group,
sidewalks, driveways, parking lots and any other common areas available to

<PAGE>

Areas"), subject in all cases to the provisions of this Agreement. In order to

cause the applicable member of its Group to execute and deliver herewith an

be other than in its present condition. The parties expressly acknowledge that
this Agreement does not constitute a demise by Parent or a Parent Group member
of any real property interest in the Leased Premises (including, without
limitation, the Space) and, consequently, neither Sub nor any Sub Group member
shall be entitled to any rights or remedies to which a subtenant may be entitled
at law or in equity, unless such party shall have been expressly afforded such
rights and remedies pursuant to the provisions of this Agreement. This Agreement
is subject and subordinate to the Master Leases and, consequently, if any Master
Lease expires or terminates for any reason whatsoever, the Space License with
respect to the Leased Premises thereunder shall expire.

     Section 2.2  Related Services.  During the term of this Agreement, Parent
                  ----------------
will provide, or cause to be provided, the following services (the "Related
Services") related to Sub's use and occupancy of the Space:

             (a)  all utilities consumed on or in connection with the use and
     occupancy of the Space, including but not limited to water, sewer, gas,
     electricity, heat, ventilation and air conditioning;

             (b)  maintenance services for the applicable building (e.g.,
     janitorial/custodial, repairs, elevators, plants) and for the grounds on
     the Leased Premises (e.g., landscaping, snow removal, paving) with respect
     to the Space (including all rest rooms located in the building and all
     parking lots and walkways, sidewalks, and driveways providing for access to
     and from the Space);

             (c)  receipt and distribution of Sub's incoming and outgoing mail
     and other shipments and deliveries; and

             (d)  reception and security services.

Parent will provide, or cause a member of the Parent Group to provide, each of
the Related Services with respect to the Space and Sub's operations conducted
thereat to the extent required to accommodate Sub's reasonable needs, and in the
same manner of quality, quantity and timeliness as such services are provided to
the rest of the building and the Leased Premises and the operations conducted
therein, but in no event in a materially lesser manner than such services were
provided prior to the date hereof.

     Section 2.3  Consents.  Parent and Sub shall cooperate and use reasonable
                  --------
efforts to obtain, and cause the members of their respective Group to obtain,
any required consents of Landlords or other Persons with respect to the Space
License granted hereunder. All fees and

                                       3
<PAGE>

expenses incurred by the parties (including the reasonable fees and expenses of
counsel to the parties) in connection with obtaining third party consents shall
be paid by Sub.

            -----------
"License Fee") for the use and occupancy of the Space, including the Common
Areas and the provision of the Related Services, in the aggregate amount as set
forth on any Schedule B attached hereto, in each case payable on the first
             ----------
business day of each calendar month during the term of this Agreement. Sub shall
pay the License Fee with respect to a particular Leased Premise until the
termination of the License for such Leased Premise.  The parties acknowledge and
agree that the License Fee with respect to the Space shall be based on the
applicable rent for such Leased Premises and Sub's proportionate use and
occupancy of Space at such Leased Premises, and shall be computed in accordance
with the parties' past practices in respect of similar facilities fees relating
to the Leased Premises prior to the Effective Date.  With respect to any period
of use or occupancy of the Space, which is less than a full calendar month, the
License Fee with respect to such period shall be appropriately pro-rated.

SECTION 4.  LIMITATION OF LIABILITY; INDEMNIFICATION.
            ----------------------------------------

CONSEQUENTIAL, INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES OR LOST PROFITS, HOWEVER
CAUSED AND ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE) ARISING IN ANY WAY

OF SUCH DAMAGES.  Notwithstanding the foregoing, each of Parent and Sub shall
indemnify and hold harmless the other against any claims, liability, loss,
damage or expense (including reasonable attorneys' fees and disbursements)

               -------------------------------------------
confirm that Parent and the members of the Parent Group own all right, title and
interest in and to the Covered Intellectual Property, and that other than the
Licenses granted to Sub hereunder, Parent and the members of the Parent Group

all times during the Term, Sub shall, and shall cause the other members of the
Sub Group to, at Parent's request, assist Parent in the procurement and
maintenance of Parent's rights in the Covered Intellectual Property, including,
without limitation, the execution and delivery of all documents and instruments
that Parent deems reasonably necessary to protect its rights in the Covered
Intellectual Property, and any legends or notices on Sub materials and products
as may be required by applicable law or reasonably requested by Parent. In
addition, Sub shall not, and shall cause the other members of the Sub Group not

or record any such security interest in the United States Patent and Trademark
Office or elsewhere.

Agreement, Parent, as licensor, does hereby grant to Sub, as licensee,
commencing on the Effective Date, a perpetual, irrevocable, fully paid-up,
royalty-free, world-wide license to use and display the Covered Marks in any
medium in connection with the promotion, marketing, advertising, publicity and
operation of the Sub Business (the "Marks License"). The Marks License shall be
exclusive to Sub with respect to the Designated Industry during the Exclusivity
Period, and thereafter shall be non-exclusive for all purposes.

         2.3.  Technology License.
               ------------------

         (a)   Subject to the terms and conditions of this Agreement, Parent, as

paid-up, royalty-free, world-wide license to use, publicly perform, display,
copy, have copied, modify, have modified, market, distribute and sublicense the

the operation of the Sub Business (the "Technology License"). Sub may exercise
the Licenses set forth in this Section 2.3 directly or indirectly through
resellers, distributors, sales representatives or remarketers. The Technology
License shall be exclusive to Sub with respect to the Designated Industry during

         2.4.  Name License.  Subject to the terms and conditions of this
               ------------
Agreement, Parent, as licensor, does hereby grant to Sub, as licensee,
commencing on the Effective Date and continuing until the date which is the
fifth anniversary of the IPO Closing Date, subject to earlier termination as
provided herein (the "Name License Term"), a fully paid-up, royalty-free, world-
wide license to use and display the Parent Name in connection with the operation
of the Sub Business (the "Name License"). The Name License shall be exclusive to
Sub with respect to the Designated Industry during the Exclusivity Period, and
thereafter shall be non-exclusive for all purposes.

         2.5.  Prohibited Uses.  All rights not specifically granted hereunder
               ---------------
shall be considered specifically excluded from the grant of the Licenses.
Without limiting the generality of the foregoing, Sub shall not, and shall cause
each other member of the Sub Group not to:

               2.5.1.  sub-license the use of the Covered Intellectual Property
to any Person other than a member of the Sub Group; and

               2.5.2.  use the Covered Intellectual Property in a manner which
is inconsistent with its use by Parent and Sub on the Effective Date.

         2.6.  DISCLAIMER OF WARRANTIES.  NOTHING IN THIS AGREEMENT SHALL BE
               ------------------------
DEEMED TO BE A REPRESENTATION OR WARRANTY BY PARENT, AS LICENSOR, OF THE SCOPE,
VALIDITY, ENFORCEABILITY, VALUE OR FREEDOM FROM INFRINGEMENT OF THIRD PARTY
INTELLECTUAL PROPERTY RIGHTS OF ANY OF THE COVERED INTELLECTUAL PROPERTY.
PARENT, AS LICENSOR, SHALL NOT HAVE ANY LIABILITY WHATSOEVER TO SUB, AS
LICENSEE, OR TO ANY OTHER PERSON ON ACCOUNT OF ANY INJURY, LOSS OR DAMAGE, OF
ANY KIND OR NATURE, SUSTAINED BY, OR ANY DAMAGE ASSESSED OR ASSERTED AGAINST, OR
ANY OTHER LIABILITY INCURRED BY OR IMPOSED UPON SUB, AS LICENSEE, OR ANY OTHER
PERSON, ARISING OUT OF OR IN CONNECTION WITH OR RESULTING FROM (a) THE
PRODUCTION, USE OR SALE OF ANY APPARATUS OR PRODUCT THROUGH THE USE OR PRACTICE
OF ANY OF THE COVERED INTELLECTUAL PROPERTY, (b) THE OTHER USE OF ANY OF THE
COVERED INTELLECTUAL PROPERTY OR (c) ANY ADVERTISING OR OTHER PROMOTIONAL
ACTIVITIES WITH RESPECT TO ANY OF THE FOREGOING.

                                       4

         2.7.  Reorganization. The Licenses granted herein are part of the
               --------------
contribution by Parent to Sub of the Sub Business in a transaction or
transactions described in Section 351 of the Code, and as such, the
consideration given by Sub in exchange for the rights granted hereunder consists
solely of the Sub Shares and the assumption of the Assumed Liabilities as
described in the Reorganization Agreement.

         2.8.  Infringement of Covered Intellectual Property.  In the event that
               ---------------------------------------------
either Parent or Sub learns that any entity is or may be infringing in any way
on any of the Covered Intellectual Property licensed hereunder, or is engaged in
conduct which is liable to cause deception or confusion to the public, or is
diluting or infringing any right of the parties hereto, such party shall notify
the other party. Parent shall have the sole initial right to determine whether
or not any action shall be taken against such unauthorized use or infringement.
Parent shall promptly notify Sub of its determination and shall briefly describe
the action, if any, which it shall take. In the event that Parent initiates
litigation against any entity, Parent shall choose the attorneys, control the
litigation, pay the litigation expenses, and retain any settlement amount or
damages recovered as a result of any judgment in favor of Parent. In the event
that Parent takes no action to stop such alleged unauthorized use or
infringement within sixty (60) days following notice by Sub or Parent, as the
case may be (or such earlier date as Sub reasonably determines is necessary to
avoid prejudicing the parties' ability to bring an action with respect to such
alleged unauthorized use or infringement), of such unauthorized use or
infringement, then Sub may either (i) initiate litigation or such other action
with respect to protesting its rights granted hereunder against such
unauthorized use or infringement, or (ii) by written notice to Parent, request
that Parent bring an action with respect to such alleged unauthorized use or
infringement at the expense of Sub, in which event Parent shall promptly
commence such action, but only if Sub certifies to Parent that in Sub's good
faith judgment failure to take action against the unauthorized use or
infringement in question is likely to have a material adverse effect on the Sub
Business. Any settlement amount or damages awarded in any such suit referenced
in the preceding sentence shall, after payment of expenses incurred by the
parties, be paid to Sub.

         In any action taken pursuant to this Section 2.8, Sub shall reasonably
cooperate with Parent in all respects, to have the appropriate employees of Sub
assist in the preparation of the suit and testify if requested by Parent, and to
make available any records, papers, information, specimens and the like.

         Except as expressly provided herein, all expenses incurred in
connection with actions taken pursuant to this Section 2.8 shall be borne
independently by each of the parties, with each party being liable solely for
the fees and expenses it incurs in connection with such action.

                         3. NON-DISCLOSURE AGREEMENTS

         Sub shall, and shall cause the other members of the Sub Group, to cause
their respective employees, promptly after the Effective Date, to enter into and
execute non-disclosure agreements, in form and substance reasonably satisfactory
to Parent and on terms not least as restrictive as the confidentiality
provisions in the Reorganization Agreement, governing the use by such employees
of confidential information relating to Parent, including, without limitation,
confidential information relating to the Technology, and shall take all
reasonable steps necessary to enforce each such non-disclosure agreement after
its execution.

                                    4. TERM

         Except for the Name License, which shall continue in effect until
expiration of the Name License Term, this Agreement shall continue in effect in
perpetuity from the Effective Date, unless earlier terminated by agreement among
the parties; provided, however, that the provisions of Sections 2.8, 3, 5.1 and
5.2 shall remain in effect indefinitely or until such time as the obligations of
both parties hereunder shall have been fully discharged.

                               5. MISCELLANEOUS

         5.1.  Confidentiality. The provisions of Section 8 of the
               ---------------
Reorganization Agreement relating to confidentiality shall apply with respect to
any information obtained or learned by either party from the other party in
connection with the assignments and licenses contemplated hereby. This Section
shall survive the termination of this Agreement.

         5.2.  Dispute Resolution. All disputes, controversies or claims between
               ------------------
Parent and Sub arising out of or relating to this Agreement, including, without
limitation, the breach, interpretation or validity of any term or condition
hereof, shall be resolved in accordance with the provisions of the
Reorganization Agreement relating to dispute resolution.

         5.3.  Amendment and Waiver.  The provisions of this Agreement,
               --------------------
including, without limitation, this Section, may not be waived and this
Agreement shall not be amended or modified except in accordance with this
Section. The provisions of this Agreement may be waived only by the written
consent of a majority of the Independent Directors of the party which is the
beneficiary of the particular provision being waived. No failure or delay by any
party in exercising any right or remedy hereunder shall operate as a waiver
thereof, and a waiver of a particular right or remedy on one occasion shall not
be deemed a waiver of any other right or remedy or a waiver on any subsequent
occasion. The provisions of this Agreement may be amended, modified or
supplemented only by the written consent of a majority of the Independent
Directors of each of the parties.

         5.4.  Notices.  Any notice to any party hereto given pursuant to this
               -------
Agreement shall be in writing and shall be given by the means, and to the
addresses, set forth in the "Notices" section of the Reorganization Agreement.

         5.5.  Successors and Assigns. This Agreement may not be assigned by
               ----------------------
either party without the prior written consent of the other party, and any
attempt to assign any rights or obligations hereunder without such consent shall
be void; provided, however, that either party may assign or transfer this
         --------  -------
Agreement without the consent of the non-assigning party to an entity that
succeeds to all or substantially all of the business, assets or capital stock of
such party or to another member of such party's Group (until such time as such
Person is no longer a member of such Group). This Agreement shall inure to the
benefit of, and be binding upon and enforceable against the respective
successors and assigns of the parties hereto.

         5.6.  Entire Agreement; Parties in Interest. This Agreement (including
               -------------------------------------
the Schedules hereto and the provisions of the Reorganization Agreement
incorporated herein by reference) comprises the entire agreement between the
parties hereto as to the subject matter hereof and supersedes all prior
agreements and understandings between them relating thereto and is not intended
to confer upon any person other than the parties hereto (including their
successors and permitted assigns) any rights or remedies hereunder.

         5.7.  Severability. If any term or provision of this Agreement or the
               ------------
application thereof to any person or circumstance shall to any extent be invalid
or unenforceable, the remainder of this Agreement or the application of such
terms or provisions to persons or circumstances other than those as to which it
is invalid or unenforceable shall not be affected thereby and each term and
provision of this Agreement shall be valid and enforced to the fullest extent
permitted by law.

         5.8.  Captions.  Captions and headings are supplied herein for
               --------
convenience only and shall not be deemed a part of this Agreement for any
purpose.

         5.9.  Governing Law.  This Agreement shall be governed by and construed
               -------------
in accordance with the internal substantive laws of the Commonwealth of
Massachusetts, without giving effect to the principles of conflicts of laws
thereof.

         5.10. Counterparts.  This Agreement may be executed in several
               ------------
counterparts, and all counterparts so executed shall constitute one agreement,
binding upon the parties hereto, notwithstanding that the parties are not
signatory to the same counterpart.
