("Tenant").

                             W I T N E S S E T H:
                             - - - - - - - - - -

      WHEREAS, Landlord is the owner of the real property and an office building
consisting of approximately 250,000 square feet, located within the Pope
Technical Park in Hillsborough County, New Hampshire, commonly known as Building

is attached hereto as Exhibit A;

      WHEREAS, pursuant to the terms of the Purchase Agreement between Landlord
and Tenant dated as of January 22, 1998 (together with all Exhibits, Schedules
and Attachments thereto, the "Purchase Agreement"), Tenant has agreed to lease
the Premises from Landlord on the terms and conditions set forth in this Lease;
and

      NOW, THEREFORE, in consideration of the mutual covenants and agreements of
the parties contained herein and contained in the Purchase Agreement, the
parties agree as follows:

                                   ARTICLE I
                                     TERM

      Section 1.01 Term. The term (the "Prime Term") of this Lease shall
commence on the date hereof (the "Commencement Date") and shall continue for a
period of two years thereafter (the "Expiration Date").

      Section 1.02 ADDITIONAL TERM. In the event that Tenant shall desire to
extend this Lease at the end of the Prime Term, Tenant shall be permitted to
extend this Lease for one additional term for a period of up to four years
following the expiration of the Prime Term (the "Additional Term"). Tenant shall
provide Landlord written notice of the intent to lease the Premises for the
Additional Term at least 90 days before the expiration of the Prime Term. Upon
receipt of such written notice by Landlord, Landlord and Tenant shall negotiate
in good faith a lease for the Premises for the Additional Term on terms and
conditions consistent with the general market for the lease of commercial
facilities of the type, location and size of the Premises at that time (the
"General Market Rate"). Notwithstanding the foregoing, in the event that despite
such good faith negotiations Landlord and Tenant are unable

                                    V-1

to agree on the General Market Rate for the Additional Term, the General Market
Rate shall be determined in accordance with the provisions of Section 1.03
below.

      Section 1.03.     APPRAISAL.

      (a) In the event that Landlord and Tenant cannot agree on the General
Market Rate within 60 days of the Expiration Date, then either party may invoke
its right to appraisal as set forth in this Section 1.03.

      (b) To invoke its right to appraisal, the invoking party (the "Invoking
Party") shall send written notice to the other party (the "Non-Invoking Party")
stating that it is invoking its right to appraisal and naming an appraiser with
substantial experience in commercial real estate matters in the general area in
which the CE Facility is located, who shall be a member of the Appraisal
Institute or some other comparable organization. Within 10 days after such
notice, the Non-Invoking Party shall name an appraiser who is also so qualified
and shall provide the Invoking Party with written notice of the same. Within 10
days thereafter, the two appraisers so selected (the "First Appraisers") shall
select a third appraiser (the "Outside Appraiser").

      (c) The appraisers (the First Appraisers and the Outside Appraiser) shall
attempt to determine the General Market Rate for the Premises. In making such
determination, the appraisers shall take into account that the Additional Rent
set forth in Section 3.02 of this Lease shall continue without interruption. In
the event that the First Appraisers are unable to determine a single General
Market Rate within 20 days after the date the Outside Appraiser was selected,
each of the First Appraisers shall set his or her own General Market Rate. In
the event that the General Market Rate determined by either of the First
Appraisers is within 10% (a "Close Appraisal") of the General Market Rate
established by the Outside Appraiser (the "Outside Appraisal"), the average of
the Close Appraisal or the Close Appraisals, as the case may be, and the Outside
Appraisal shall be the General Market Rate. In the event that neither appraisal
by the First Appraisers is a Close Appraisal, the General Market Rate shall be
(i) the Outside Appra.isal if it falls between the other two appraisals, (ii)
the average of the Outside Appraisal and the lower of the other two appraisals
if the outside Appraisal is lower than both of the other two appraisals, and
(iii) the average of the Outside Appraisal and the higher of the other two
appraisals if the Outside Appraisal is higher than both of the other two
appraisals. The General Market Rate so determined shall be conclusive and
binding upon the parties.

      (d) Each party shall bear all of the costs and expenses of the appraiser
selected by it and the parties shall share equally the costs of the outside
Appraiser.

                                    V-2

otherwise required by, applicable State of New Hampshire utilities laws. Any

Tenant of a written request for payment thereof and reasonable documentation
regarding such Additional Rent.

                        BANKRUPTCY, WAIVER OR DEFAULT

      Section 17.01 BANKRUPTCY, WAIVER OR DEFAULT. In the event Tenant files a
voluntary petition in bankruptcy, makes assignment for the benefit of creditors,
or is adjudged a bankrupt, or if a receiver, trustee or custodian is appointed
for Tenant by any court, or if Tenant files any petition for relief under any
section of the bankruptcy laws of the United States now in force or hereafter
enacted, or if Tenant takes advantage of any insolvency act, or if the interest
of Tenant shall be sold under any execution or other legal process issued out of
any court, or if Tenant shall abandon or vacate the Premises during the term of
this Lease, or if Tenant shall breach any promise or covenant herein, then in
any such event it shall be lawful for Landlord at any time thereafter, at its
option upon 10 days written notice to Tenant, to re-enter said premises and
again have possession thereof and occupy the same as if this Lease had not been
made, and thereupon this Lease shall cease and become null and void.

                                SUBORDINATION

      Section 18.01 SUBORDINATION. This Lease shall be subject and subordinate
to any and all mortgages, deeds of trust and other instruments in the nature of
a mortgage, now or at any time hereafter recorded, other than the Mortgage and
Promissory Note dated July 28, 1982 between Hi-Tension Realty Corporation,
Mortgagor, and Ernest Chalifoux, Ethel Chalifoux and Mildred Chalifoux,
Mortgagees, which Landlord has represented and does represent to Tenant is
invalid, and Tenant shall, when requested, promptly execute and deliver such
written instruments as shall be necessary to show the subordination of this
Lease to said mortgages, deeds of trust or other such instruments in the nature
of a mortgage. Notwithstanding anything in this Lease to the contrary, a
condition precedent to the effectiveness of the subordination described in this
paragraph, shall be that the holder of any mortgage, ground lease or other
security instrument to which this Lease is to be subordinated or to whom Tenant
is to attorn, shall agree pursuant to a written agreement (hereinafter referred
to as a "Non-Disturbance Agreement") delivered to Tenant, that (i) so long as
Tenant is not in default under this Lease (beyond any period given to Tenant
hereunder to cure such default), Tenant's use and occupancy of the Premises and
its rights under this Lease shall not be disturbed or affected by the
termination of such ground or underlying lease prior to the expiration or
termination of this Lease or by any foreclosure or other action (or by the
delivery or acceptance of a deed or other conveyance or transfer in lieu
thereof) which may be instituted or undertaken in order to enforce any right or
remedy available to the holder of such instrument, (ii) Tenant shall not be
named as a party defendant in any foreclosure, summary or any other action
commenced by any such ground or underlying lessor or secured party, and (iii)
any party succeeding to the interest of Landlord as a result of any such
enforcement action or otherwise shall be bound to Tenant, and Tenant shall be
bound to it, under all of the terms, covenants and conditions of this Lease with
the same force and effect as if such party were the original Landlord under this
Lease. Landlord covenants and agrees that it will obtain and deliver to Tenant a
Non-Disturbance Agreement in accordance with the foregoing provisions from the
then holder(s) of any mortgage, deed of trust, ground lease or other security
instrument affecting the Premises on or before the date the Premises are ready
for occupancy, failing which tenant may, at its option, terminate this Lease
whereupon any prepaid rent or other prepaid charges or deposits paid by Tenant
to Landlord shall be immediately refunded.

      Section 19.02 EMINENT DOMAIN. If the whole or any part of the Premises
shall be taken by public authority under the power of eminent domain, then the
term of this Lease shall cease on the part so taken from the day that possession
of that part shall be required for any purpose by said public authority, and the
rent and the Additional Rent shall be paid up to that day, and if such portion
of the Premises are so taken as to, in Tenant's opinion, destroy the usefulness
of the Premises for the purpose for which the Premises were leased, then, from
that day, Tenant shall have the right either to terminate this Lease and declare
the same null and void, or to continue in the possession of the remainder of the
same under the terms herein provided, except that the rent shall be reduced in
proportion to the amount of the Premises taken based on the value of the portion
taken to the value of the remaining part. All damages awarded for such taking
shall belong to and be the property of Landlord, including such damages as shall
be awarded as compensation for diminution in value to the leasehold, provided,
however, that Landlord shall not be entitled to any portion of the award made to
Tenant for Tenant's furnishings or Tenant's business relocation expenses.

      Section 19.03 DESTRUCTION OF PREMISES. If, during the term of this Lease,
the Premises are totally or partially destroyed from any cause, rendering the
Premises totally or partially inaccessible or unusable, Landlord shall restore
the destruction if the restoration can be made under the existing laws and can
be completed within 120 working days after the destruction. Such destruction
shall not terminate the Lease. During the period that the Premises are being
restored Tenant shall neither pay nor owe the rent pursuant to either Section
3.01 or the Additional Rent to Landlord. If the restoration cannot be made
within 120 days, then within 10 days after such destruction Tenant or Landlord
can terminate this Lease immediately by giving written notice and neither party
shall have any further obligation to the other with respect to this Lease.

      Section 19.04 ENTIRE AGREEMENT. Except as otherwise expressly contemplated
by the Purchase Agreement, this Lease and the Purchase Agreement contain all
representations, understandings, agreements and commitments of Landlord and
Tenant. The Lease between Lockheed Sanders, Inc. and CE dated September 26,

type whatsoever shall be null and void and of no effect whatsoever in the
interpretation of this Lease.

      Section 19.05 APPLICABLE LAW; JURISDICTION. This Lease shall be construed
in accordance with the laws of the State of New Hampshire without reference to
the conflicts of laws principles

                                    V-14
