         EXHIBIT A  Plan of Premises

                                   ARTICLE II
                                PREMISES AND TERM

2.1 PREMISES.

         Landlord hereby leases to Tenant, and Tenant leases from Landlord the
Premises for the rents hereinafter reserved, and upon and subject to the terms
and conditions of this Lease.

2.2 APPURTENANT RIGHTS AND RESERVATIONS.

         Tenant shall have, as appurtenant to the Premises, the nonexclusive
right to use and to permit its invitees to use in common with others the Parking
Spaces Allocated to Tenant and the other Common Areas (as defined below) of the
Property. Such rights shall always be subject to reasonable rules and
regulations from time to time established by Landlord by written notice to
Tenant in advance and to the right of Landlord to reasonably designate and
change from time to time any Common Areas provided (i) Tenant is given written
notice before any such change and (ii) any such change does not materially
adversely affect Tenant's ability to use the Premises for the Permitted Uses.

         As used in this Lease, "Common Areas" shall mean all areas within the
Property which are not part of the rentable areas of the Buildings, including,
but not limited to, lobbies, loading docks, parking areas, driveways, sidewalks,
access roads, landscaping, and planted areas.

2.3 TERM.

         The Premises are leased for the Term unless the Term shall sooner
terminate pursuant to any of the terms of this Lease or pursuant to Law.

                                  ARTICLE III
                       DELIVERY OF PREMISES; CONSTRUCTION

3.1 AS IS DELIVERY.

         Landlord is leasing and delivering the Premises to Tenant "as is,"
without any representations or warranties of any kind (including, without
limitation, any express or implied warranties of merchantability, fitness or
habitability), subject to all recorded matters, laws, ordinances, and
governmental regulations and orders. Tenant acknowledges that it has been the
tenant of the Premises prior to the execution of this



                                       3
<PAGE>   7


Lease and the Commencement Date and that it is fully aware of, and accepts the
condition of, the Premises as they are on the date hereof.

3.2 GENERAL PROVISIONS APPLICABLE TO CONSTRUCTION.

         Tenant shall not make any installations, alterations, additions, or
improvements in or to the Premises, including, without limitation, any apertures
in the walls, partitions, ceilings or floors, without, on each occasion where
such installations, alterations, additions or improvements will cost in excess
of $50,000, obtaining the prior written consent of Landlord which shall not be
unreasonably withheld. Tenant shall reimburse Landlord for all costs incurred by
Landlord or any Superior Mortgagee (as defined below) in reviewing Tenant's
proposed installation, alterations, additions or improvements. Any such work so
approved by Landlord shall be performed only in accordance with plans and
specifications therefor approved by Landlord. Tenant shall procure at Tenant's
sole expense all necessary permits and licenses before undertaking any work on
the Premises and shall perform all such work in a good and workmanlike manner
employing materials of good quality and so as to conform with all applicable
insurance requirements, laws, ordinances, regulations and orders of governmental
authorities. Tenant shall employ for such work only contractors reasonably
approved by Landlord and shall require all contractors employed by Tenant to
carry worker's compensation insurance in accordance with statutory requirements
and commercial general liability insurance covering such contractors on or about
the Premises with a combined single limit not less than $2,000,000 and shall
submit certificates evidencing such coverage to Landlord prior to the
commencement of such work. Landlord acknowledges that Tenant may use its own
employees to perform work and maintenance at the Premises. Tenant shall
indemnify and hold harmless Landlord from all injury, loss, claims or damage to
any person or property occasioned by or growing out of such work. Landlord may
inspect the work of Tenant at reasonable times and give notice of observed
defects. Upon completion of any such work, Tenant shall provide Landlord with
"as built" plans, copies of all construction contracts and proof of payment for
all labor and materials. Notwithstanding the foregoing, Landlord's consent shall
not be required for any alterations or improvements to the Premises which do not
affect the structural integrity of the Premises or any of the Building systems
and which cost less than $50,000.

                                   ARTICLE IV
                                      RENT

4.1 BASE RENT.

         Beginning on the Commencement Date, Tenant agrees to pay base rent to
Landlord without notice or demand and without any offset or reduction whatever
(except as made in accordance with the express provisions of this Lease), equal
to the Base Rent in equal monthly installments in advance on the first day of
each calendar month included in the Term. If the Commencement Date occurs on a
day other than the first day of a calendar month, Tenant shall pay to Landlord,
on the Commencement



                                       4
<PAGE>   8


Date, Base Rent for the partial month after the Commencement Date at the
proportionate rate payable for such portion.

4.2 ADDITIONAL RENT.

         All sums payable by Tenant under this Lease other than Base Rent shall
be deemed "Additional Rent;" the term "Rent" shall mean Base Rent and Additional
Rent. Landlord shall reasonably estimate in advance by written notice to Tenant
at least thirty days in advance and charge to Tenant the following costs (the
"Total Operating Costs"), to be paid with the Base Rent throughout the Term in
equal monthly installments based on Landlord's most recent reasonable estimate:
(i) all Real Property Taxes for which Tenant is liable under Section 4.3 of the
Lease, (ii) all utility costs (if not separately metered) for which Tenant is
liable under Section 6.1.1 of the Lease, (ill) all insurance premiums for which
Tenant is liable under Section 5.1.2 of the Lease and (iv) all roof and parking
lot repair and maintenance costs for which Tenant is liable under Section 5.1.3
of the Lease. Landlord may adjust its estimates of Total Operating Costs at any
time based upon Landlord's experience and reasonable anticipation of costs, upon
at least ten business days prior written notice specifying the reasons for any
adjustments. Such adjustments shall be effective as of the next Rent payment
date after notice to Tenant. Within 120 days after the end of each fiscal year
(which shall be January 1 through December 31 for this Lease) during the Term,
Landlord shall deliver to Tenant a statement (the "Statement") prepared in
accordance with generally accepted accounting principles setting forth, in
reasonable detail, the Total Operating Costs paid or incurred by Landlord during
the preceding fiscal year. Within thirty days after Tenant's receipt of such
Statement, there shall be an adjustment made in good faith between Landlord and
Tenant, with payment to or credit given by Landlord (as the case may be) in
order that Landlord shall have received the actual amount of Total Operating
Costs for such period. Tenant (and its accountants and representatives) shall
have the right, within thirty days of receipt of the Statement, to notify
Landlord that it would like to audit Landlord's books and records with respect
to the Total Operating Costs. Such audit is to be at Tenant's sole cost and
expense (except as provided in the following sentence) and is to performed and
completed within two months of the receipt of the Statement by Tenant. If such
audit reveals that the Total Operating Costs billed to Tenant exceed the actual
Total Operating Costs by more than five percent, Landlord shall pay the
reasonable costs of such audit.

         In addition to its obligation to pay Base Rent and Total Operating
Expenses, Tenant is required hereunder to pay directly to suppliers, vendors,
carriers, contractors, etc. certain maintenance expenses, insurance premiums,
utility costs, personal property taxes, cleaning and other expenses
(collectively "Additional Expenses"). If Landlord pays for any Additional
Expenses in accordance with the terms of this Lease, Tenant's obligation to
reimburse such costs shall be an Additional Rent obligation. Unless this Lease
provides otherwise, Tenant shall pay all Additional Rent then due with the next
monthly installment of Base Rent due after Tenant received written notice of the
amount of such Additional Rent.




                                       5

4.3 REAL PROPERTY TAXES.

         Tenant shall pay to Landlord Tenant's Pro Rata Share of all Real
Property Taxes on the Premises attributable to any period included in the Term;
provided, however, if the Term includes only a portion of a fiscal tax period,
the Real Property Taxes for such period shall be prorated according to the
fraction of the total days in such period falling within the Term, and Tenant
shall be responsible for paying only such prorated amount. The term "Real
Property Taxes" shall mean taxes, assessments (special, betterment, or
otherwise), levies, fees, rent taxes, impositions, excises, charges, water and
sewer rents and charges, and all other government levies and charges, general
and special, ordinary and extraordinary, foreseen and unforeseen, which are
imposed or levied upon or assessed against the Premises or any Rent or other
sums payable by any tenants or occupants thereof. If at any time during the term
the present system of ad valorem taxation of real property shall be changed so
that in lieu of the whole or any part of the ad valorem tax on real property, or
in lieu of increases therein, there shall be assessed on Landlord a capital levy
or other tax on the gross rents received with respect to the Property or a
federal, state, county, municipal, or other local income, franchise, excise or
similar tax, assessment, levy, or charge distinct from any now in effect)
measured by or based, in whole or in part, upon gross rents, then all of such
taxes, assessments, levies, or charges, to the extent so measured or based,
shall be deemed to be a Real Property Tax. Notwithstanding any other provision
of this Lease, Real Property Taxes shall not include, and Tenant shall have no
obligation to pay, any taxes on Landlord's net income.

         Landlord shall have the right, but not the obligation, to dispute any
Real Property Taxes attributable to any fiscal tax period included wholly or
partially within the Term. The cost of such contest shall be included in the
calculation of Total Operating Costs.

4.4 PAYMENTS.

         All payments of Rent shall be made to Landlord at the address specified
in Section 1.1, or to such other person as Landlord may from time to time
designate by written notice to Tenant. If any installment of Rent is paid more
than 5 days after the due date thereof, at Landlord's election, it shall bear
interest from such due date at a rate equal to the average prime commercial rate
from time to time established by BankBoston plus 4% per annum, which interest
shall be immediately due and payable as further Additional Rent. Notwithstanding
the foregoing, the first time in each Lease Year that Tenant is late in the
payment of any installment of Rent, interest shall not be charged until 10
business days after Tenant receives written notice of such non-payment.

                                   ARTICLE V
                              LANDLORD'S COVENANTS

         5.1.1 Quiet Enjoyment. That Landlord has the right to make this Lease
and that Tenant on paying the Rent and performing its obligations hereunder
shall peacefully and quietly have, hold and enjoy the Premises throughout the
Term without any manner of hindrance or molestation from Landlord or anyone
claiming under Landlord, subject however to all the terms and provisions hereof.

         5.1.2 Insurance. During the Term, Landlord shall maintain in effect all
risk insurance covering loss of or damage to the Buildings and other
improvements at the Property in the amount of its replacement value with such
endorsements and deductibles as Landlord shall reasonably determine from time to
time. Landlord shall have the right to obtain flood, earthquake, and such other
insurance as Landlord shall reasonably determine from time to time or shall be
required by any lender holding a security interest in the Premises. Landlord
shall not obtain insurance for Tenant's trade fixtures, equipment or building
improvements. During the Term, Landlord shall also maintain a rental income
insurance policy, with loss payable to Landlord, in an amount equal to one
year's Base Rent, plus estimated Real Property Taxes, operating costs for the
Property, and insurance premiums. Tenant shall not do or permit anything to be
done which shall invalidate any such insurance. Any policy obtained by Landlord
shall not be contributory, shall not provide primary insurance, and shall be
excess over any insurance maintained by Tenant. Landlord shall also maintain
during the Term a policy of general liability insurance with respect to the
Premises naming Tenant as an additional insured.

8.1 SUBORDINATION.

         This Lease and all rights of Tenant hereunder shall be subject and
subordinate in all respects to (a) all present and future ground leases,
operating leases, superior leases,


                                       14
<PAGE>   18


overriding leases and underlying leases and grants of term of the Premises or
any portion thereof (collectively, including the applicable items set forth in
Subdivision (d) of this Section 8.1, the "Superior Lease") whether or not the
Superior Lease shall also cover other lands or buildings, (b) all mortgages and
building loan agreements, including leasehold mortgages, which may now or
hereafter affect the Premises or the Superior Lease (collectively, including the
applicable items set forth in Subdivisions (c) and (d) of this Section 8.1, the
"Superior Mortgage"), whether or not any Superior Mortgage shall also cover
other lands or buildings or leases, (c) each advance made or to be made under
any Superior Mortgage, and (d) all renewals, modifications, replacements,

Lease shall have priority over such Superior Mortgage and, upon notification
thereof by such Superior Mortgagee to Tenant, this Lease shall be deemed to have
priority over such Superior Mortgage, whether this Lease is dated prior to or
subsequent to the date of such Superior Mortgage. If, in connection with the
obtaining, continuing or renewing of financing for which the Premises or the
interest of the lessee under the Superior Lease represents collateral, in whole
or in part, any bank, insurance company, pension fund or other lending
institution shall request reasonable modifications of this Lease as a condition
of its granting such financing, Tenant will not unreasonably withhold its
consent thereto, provided that such modifications do not increase the Base Rent,
materially and adversely increase the obligations of Tenant hereunder or
materially and adversely affect Tenant's rights hereunder. Tenant agrees that it
will take no steps to terminate this Lease or abate Rent payable hereunder
without giving each lessor under a Superior Lease (a "Superior Lessor"), and any
Superior Mortgagee requesting same, written notice of any default by Landlord
and the opportunity to cure such default (without any obligation on the part of
any such person to cure such default) within 45 days thereafter or, if such
Superior Lessor or Superior Mortgagee commences such cure within 30 business
days and diligently pursues such cure, such longer period as may be reasonably
necessary to effect such cure. Landlord shall endeavor to obtain a subordination
and non-disturbance agreement, in recordable form, for each present and future
Superior Mortgagee or Superior Lessor.

8.2 SUCCESSOR LANDLORD.

         For purposes of this Section 8.2, the term "Successor Landlord" shall
mean and include (i) any person, including but not limited to any Superior
Lessor or Superior Mortgagee, who, prior to the termination of this Lease,
acquires or succeeds to the interest of Landlord under this Lease through
summary proceedings, foreclosure action, assignment, deed in lieu of foreclosure
or otherwise, and (ii) the successors and assigns of any person referred to in
clause (i) of this sentence. Upon any Successor Landlord's so acquiring, or so
succeeding to, the interest of Landlord tinder this Lease, Tenant shall, at the
election and upon the request of the Successor Landlord, fully attorn to and
recognize such Successor Landlord as Tenant's landlord under this Lease upon the
then executory terms of this Lease, but only if such Successor Landlord is bound
by a Non-Disturbance Agreement and only in accordance with such Non-Disturbance
Agreement. No Successor Landlord shall be bound by any prepayment of Rent for
more than one month in advance or any amendment or modification of this Lease
made without the


                                       15
<PAGE>   19


consent of the Superior Mortgagee or Superior Lessor from which such Successor
Landlord derives its interest in this Lease or the Premises. Upon demand of any
such Successor Landlord, Tenant agrees to execute instruments to evidence and
confirm the foregoing provisions of this Section reasonably satisfactory to any
such Successor Landlord.

prior to the due date thereof, no prepayment of the Rent (except one monthly
installment of Base Rent) or other charge, no assignment of this Lease and no
agreement to modify the Lease so as to reduce the Rent, change the Term, or
otherwise materially change the rights of Landlord under this Lease, or to
relieve Tenant of any obligations or liability under this Lease, shall be
enforceable against any Superior Mortgagees unless consented to in writing by
all Superior Mortgagees, if any.

         payment of Rent or any other monetary obligation to Landlord for more
         than 5 days, (b) in case of the delivery of any document to Landlord
         for more than 10 days or (c) in any other case for more than 30 days
         and such additional time, if any, as is reasonably necessary to cure
         the default if the default is of such a nature that it cannot
         reasonably be cured in 30 days and Tenant diligently commences and
         continues to cure such default and completes such cure within 90 days;

         similar petition under any insolvency law of any jurisdiction), or if
         such petition is filed against Tenant and not dismissed within 60 days;
         or

                  (iii) if Tenant proposes any dissolution, liquidation,
         composition, financial reorganization or recapitalization with
         creditors, makes an assignment or trust mortgage for benefit of
         creditors, or if a receiver, trustee, custodian or similar agent is
         appointed or takes possession with respect to any property of Tenant
         and such appointment or taking is not dismissed within 60 days; or if
         the leasehold hereby created is taken on execution or other process of
         law in any action against Tenant.

         If there shall be an Event of Default hereunder, Landlord and the
agents and servants of Landlord may, in addition to and not in derogation of any
remedies for any



                                       16
<PAGE>   20


preceding breach of covenant, immediately or at any time thereafter while such
Event of Default continues and without further notice, at Landlord's election,
do any one or more of the following:

                  (a) give Tenant written notice stating that the Lease is
terminated, effective upon the giving of such notice or upon a date stated in
such notice, as Landlord may elect, in which event the Lease shall be
irrevocably extinguished and terminated as stated in such notice without any
further action; or

                  (b) with process of law, in a lawful manner enter and
repossess the Premises and expel Tenant and those claiming through or under
Tenant, and remove its and their effects, without being guilty of trespass, in
which event the Lease shall be irrevocably extinguished and terminated at the
time of such entry; or

                  (c) pursue any other rights or remedies permitted by law.

         Any such termination of the Lease shall be without prejudice to any
remedies which might otherwise be used for arrears of Rent or prior breach of
covenant, and in the event of such termination Tenant shall remain liable under
this Lease as hereinafter provided. Tenant hereby waives all statutory rights
(including, without limitation, rights of redemption, if any) to the extent such
rights may be lawfully waived, and Landlord, without notice to Tenant, may store
Tenant's effects and those of any person claiming through or under Tenant at the
reasonable expense and risk of Tenant and, if Landlord so elects, may sell such
effects at public auction or private sale and apply the net proceeds to the
payment of all sums due to Landlord from Tenant, if any, and pay over the
balance, if any, to Tenant.

9.2 TENANT'S OBLIGATIONS AFTER TERMINATION.

         In the event that this Lease is terminated under any of the provisions
contained in Section 9.1 or shall be otherwise terminated for breach of any
obligation of Tenant, Tenant covenants to pay forthwith to Landlord, as
compensation, the excess of the total rent reserved for the residue of the Term
over the rental value of the Premises for said residue of the Term. In
calculating the rent reserved and the rental value, there shall be included, in
addition to the Base Rent and all Additional Rent, the value of all other
consideration agreed to be paid or performed by Tenant for said residue. Tenant
further covenants as an additional and cumulative obligation after any such
termination to pay punctually to Landlord all the sums and perform all the
obligations which Tenant covenants in this Lease to pay and to perform in the
same manner and to the same extent and at the same time as if this Lease had not
been terminated. In calculating the amounts to be paid by Tenant under the next
foregoing covenant, Tenant shall be credited with any amount paid to Landlord as
compensation as provided in the first sentence of this Section 9.2 and also with
the net proceeds of any rents obtained by Landlord by reletting the Premises,
after deducting all Landlord's reasonable expenses in connection with such
reletting, including, without implied limitation, all repossession costs,
brokerage commissions, fees for legal services and expenses of preparing the
Premises for such reletting, it being agreed by Tenant that Landlord may (i)
relet the



                                       17
<PAGE>   21


Premises or any part or parts thereof for a term or terms which may at
Landlord's option be equal to or less than or exceed the period which would
otherwise have constituted the balance of the Term and may grant such
concessions and free rent as Landlord in its reasonable judgment considers
advisable or necessary to relet the same and (ii) make such alterations, repairs
and decorations in the Premises as Landlord in its sole judgment considers
advisable or necessary to relet the same, and no action of Landlord in
accordance with the foregoing or failure to relet or to collect rent under
reletting shall operate or be construed to release or reduce Tenant's liability
as aforesaid.

         Nothing contained in this Lease shall, however, limit or prejudice the
right of Landlord to prove and obtain in proceedings for bankruptcy or
insolvency by reason of the termination of this Lease, an amount equal to the
maximum allowed by any statute or rule of law in effect at the time when, and
governing the proceedings in which, the damages are to be proved, whether or not
the amount be greater, equal to, or less than the amount of the loss or damages
referred to above.

                                   ARTICLE X
                                  MISCELLANEOUS

10.1 NOTICES FROM ONE PARTY TO THE OTHER.

         All notices, requests and other communications required or permitted
under this Lease shall be in writing and shall be personally delivered or sent
by certified mail, return receipt requested, postage prepaid or by a national
overnight delivery service which maintains delivery records. Notices to Tenant
and Landlord shall be delivered to the address specified in Article I above. All
notices shall be effective upon delivery (or refusal to accept delivery). Either
party may change its notice address upon notice to the other party.

10.2 BIND AND INURE.

         The obligations of this Lease shall run with the land, and this Lease
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that the Landlord named herein and
each successive owner of the Property shall be liable only for the obligations
accruing during the period of its ownership. The obligations of Landlord shall
be binding upon the assets of Landlord which comprise the Property and the
proceeds of any insurance or action in the nature of eminent domain relating to
the Property, but not upon other assets of Landlord. No individual partner,
trustee, stockholder, officer, director, employee, member, beneficiary, agent or
advisor of Landlord shall be personally liable under this Lease and Tenant shall
look solely to Landlord's interest in the Property, and the proceeds of any
insurance or action in the nature of eminent domain relating to the Property
remedies upon an event of default hereunder, and the general assets of the
individual partners, trustees, stockholders, officers, employees, members or
beneficiaries of Landlord shall not be subject to levy, execution or other
enforcement procedure for the satisfaction of the remedies of Tenant.



                                       18
<PAGE>   22


10.3 NO SURRENDER.

         The delivery of keys to any employee of Landlord or to Landlord's agent
or any employee thereof shall not operate as a termination of this Lease or a
surrender of the Premises.

10.4 NO WAIVER, ETC.

         The failure of Landlord or of Tenant to seek redress for violation of,
or to insist upon the strict performance of any covenant or condition of this
Lease shall not be deemed a waiver of such violation nor prevent a subsequent
act, which would have originally constituted a violation, from having all the
force and effect of an original violation. The receipt by Landlord of Base Rent
or Additional Rent with knowledge of the breach of any covenant of this Lease
shall not be deemed a waiver of such breach by Landlord, unless such waiver is
in writing and signed by Landlord. No consent or waiver, express or implied, by
Landlord or Tenant to or of any breach of any agreement or duty shall be
construed as a waiver or consent to or of any other breach of the same or any
other agreement or duty.

10.5 NO ACCORD AND SATISFACTION.

         No acceptance by Landlord of a lesser sum than the Rent then due shall
be deemed to be other than on account of the earliest installment of such Rent
due, nor shall any endorsement or statement on any check or any letter
accompanying any check or payment as Rent be deemed as accord and satisfaction,
and Landlord may accept such check or payment without prejudice to Landlord's
right to recover the balance of such installment or pursue any other remedy in
this Lease provided.

10.6 CUMULATIVE REMEDIES.

         The specific remedies to which Landlord may resort under the terms of
this Lease are cumulative and are not intended to be exclusive of any other
remedies or means of redress to which it may be lawfully entitled in case of any
breach or threatened breach by Tenant of any provisions of this Lease. In
addition to the other remedies provided in this Lease, Landlord shall be
entitled to the restraint by injunction of the violation or attempted or
threatened violation of any of the covenants, conditions or provisions of this
Lease or to a decree compelling specific performance of any such covenants,
conditions or provisions.

10.7 LANDLORD'S RIGHT TO CURE.

         If Tenant shall at any time default in the performance of any
obligation under this Lease, Landlord shall have the right, but shall not be
obligated, to enter upon the Premises and to perform such obligation,
notwithstanding the fact that no specific provision for such substituted
performance by Landlord is made in this Lease with respect to such default. In
performing such obligation, Landlord may make any payment of money or perform
any other act. All sums so paid by Landlord (together with interest at the rate
of 4% per annum in excess of the then average prime commercial rate of interest
being charged by BankBoston) and all necessary incidental costs and expenses in
connection with the performance of any such act by Landlord, shall be deemed to
be Additional Rent under this Lease and shall be payable to Landlord immediately
on demand. Landlord may exercise the foregoing rights without waiving any other
of its rights or releasing Tenant from any of its obligations under this Lease.

10.8 ESTOPPEL CERTIFICATE.

         Tenant agrees, from time to time, upon not less than 10 days' prior
written request by Landlord, to execute, acknowledge and deliver to Landlord a
statement in writing certifying that this Lease is unmodified and in full force
and effect; that, to Tenant's knowledge, Tenant has no defenses, offsets or
counterclaims against its obligations to pay the Rent and to perform its other
covenants under this Lease; that to the extent true, there is no default or
Event of Default then existing and Tenant has not received a notice of any
alleged default by Tenant under the Lease; that the Lease has not been modified
or amended (or, if there have been modifications, that this Lease is in full
force and effect as modified and stating the modifications, and, if there are
any defenses, offsets, counterclaims, or defaults, setting them forth in
reasonable detail); the dates to which the Base Rent, Additional Rent and other
charges have been paid; and such other factual matters as Landlord may
reasonably request. Any such statement delivered pursuant to this Section 10.8
shall be in a form reasonably acceptable to and may be relied upon by any
prospective purchaser or mortgagee of premises which include the Premises or any
prospective assignee of any such mortgagee.

10.9 WAIVER OF JURY TRIAL.

THE PARTIES HERETO WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
BROUGHT BY ANY PARTY(IES) AGAINST ANY OTHER PARTY(IES) ON ANY MATTER ARISING OUT
OF OR IN ANY WAY CONNECTED WITH THIS AGREEMENT OR THE RELATIONSHIP OF THE
PARTIES CREATED HEREUNDER.

10.10 ACTS OF GOD.

         In any case where either party hereto is required to do any act, delays
caused by or resulting from Acts of God, war, civil commotion, fire, flood or
other casualty, labor difficulties not limited to the Premises or Tenant's or
Landlord's business operations,


                                       20
<PAGE>   24


shortages of labor, materials or equipment, government regulations, unusually
severe weather, or other causes beyond such party's reasonable control shall not
be counted in determining the time during which work shall be completed, whether
such time be designated by a fixed date, a fixed time or a "reasonable time",
and such time shall be deemed to be extended by the period of such delay.

10.11 BROKERAGE.

         Tenant represents and warrants that it has dealt with no broker in
connection with this transaction other than the Brokers and agrees to defend,
with counsel reasonably approved by Landlord, indemnify and save Landlord
harmless from and against any and all cost, expense or liability for any
compensation, commissions or charges claimed by a broker or agent, other than
the Brokers, with respect to Tenant's dealings in connection with this Lease.
Landlord represents and warrants to Tenant that it has dealt with no broker in
connection with this transaction other than the Brokers and agrees to defend,
with counsel reasonably approved by Tenant, indemnify and save Tenant harmless
from and against any and all cost, expense or liability for any compensation,
commissions or charges claimed by a broker or agent with respect to Landlord's
dealings in connection with this Lease.

10.12 SUBMISSION NOT AN OFFER.

         The submission of a draft of this Lease or a summary of some or all of
its provisions does not constitute an offer to lease or demise the Premises, it
being understood and agreed that neither Landlord nor Tenant shall be legally
bound with respect to the leasing of the Premises unless and until this Lease
has been executed by both Landlord and Tenant and a fully executed copy has been
delivered to each of them.

10.13 APPLICABLE LAW AND CONSTRUctiON.

         This Lease shall be governed by and construed in accordance with the
laws of the state in which the Premises are located. If any term, covenant,
condition or provision of this Lease or the application thereof to any person or
circumstances shall be declared invalid or unenforceable by the final ruling of
a court of competent jurisdiction having final review, the remaining terms,
covenants, conditions and provisions of this Lease and their application to
persons or circumstances shall not be affected thereby and shall continue to be
enforced and recognized as valid agreements of the parties, and in the place of
such invalid or unenforceable provision, there shall be substituted a like, but
valid and enforceable provision which comports to the findings of the aforesaid
court and most nearly accomplishes the original intention of the parties.

         There are no oral or written agreements between Landlord and Tenant
affecting this Lease, except as specified in this Lease. This Lease may be
amended, and the provisions hereof may be waived or modified, only by
instruments in writing executed by Landlord and Tenant.

         The titles of the several Articles and Sections contained herein are
for convenience only and shall not be considered in construing this Lease,



                                       21
<PAGE>   25


         Unless repugnant to the context, the words "Landlord" and "Tenant"
appearing in this Lease shall be construed to mean those named above and their
respective heirs, executors, administrators, successors and assigns, and those
claiming through or under them respectively to there be more than one tenant,
the obligations imposed by this Lease upon Tenant shall be joint and several.

10.14 SIGNS.

         Tenant may install, at its sole cost and expense, signs on the Building
and the monument sign as presently existing. All signage must comply with all
applicable laws, codes and regulations, including, without limitation, zoning
and building codes. Tenant shall be responsible for obtaining all necessary
permits and approvals. Any changes in the location, materials, design and method
of installation of all signage, or any new signage, shall be subject to
Landlord's prior written approval.

10.15 SECURITY DEPOSIT.

         Tenant has deposited with Landlord the Security Deposit as security for
the full, faithful and punctual performance by Tenant of all of the terms of
this Lease, whether in cash or by delivery to Landlord of a clean, irrevocable
letter of credit in the amount of the Security Deposit. In the event Tenant
defaults in the performance of any of the terms of this Lease, including the
payment of Rent, Landlord may use, apply or retain the whole or any part of the
Security Deposit to the extent required for the payment of any Rent or for any
sum which Landlord may expend or may be required to expend by reason of Tenant's
default in respect of any of the terms of this Lease, including any damages or
deficiency in the re-letting of the Premises, whether accruing before or after
summary proceedings or other re-entry by Landlord. In the case of every such
use, application or retention, Tenant shall, on demand, pay to Landlord the sum
so used, applied or retained which shall be added to the Security Deposit so
that the same shall be replenished to its former amount and Tenant's failure to
do so shall be a material breach of this Lease. If the monthly Rent shall, from
time to time, increase during the Term, Tenant shall then deposit with Landlord
an additional security deposit so that the amount of such Security Deposit held
by Landlord shall at all times bear the same proportion to current Rent as the
original security deposit bears to the original monthly Rent set forth in this
Lease. Landlord shall not be required to keep such deposit separate from its
general accounts and Tenant shall not be entitled to interest on the Security
Deposit. The Security Deposit shall not be deemed a limitation on Landlord's
damages or a payment of liquidated damages or a payment of the monthly Rent due
for the last month of the Term of this Lease. If Tenant shall fully and
punctually comply with all of the terms of this Lease, the Security Deposit, or
so much of it as has not been applied by Landlord, shall be returned to Tenant,
without interest or other increment for its use, after the termination of this
Lease and after delivery of exclusive possession of the Premises to Landlord. In
the event of a sale or lease of the Building, Landlord shall have the right to
transfer the Security Deposit to the vendee or lessee and Landlord shall
immediately be released by Tenant from all liability for the return of such
Security Deposit; and Tenant agrees to look solely to the new owner or landlord
for the return of said Security Deposit; and it is agreed that the provisions
hereof shall



                                       22
<PAGE>   26


apply to every transfer or assignment made of the Security Deposit to a new
owner or landlord. Tenant shall not assign or encumber or attempt to assign or
encumber the monies deposited herein as the Security Deposit and neither
Landlord nor its successors or assigns shall be bound by any such assignment,
encumbrance, attempted assignment or encumbrance. This Lease does not create a
trust relationship between Landlord and Tenant with respect to such Security
Deposit, and Landlord shall be entitled to treat such Security Deposit as
Landlord's own property, subject only to Tenant's right to receive repayment of
it as and to the extent provided in this Section.

10.16 RENEWAL OPTIONS.

         10.16.1 Provided Tenant is not in default under this Lease and that no
event or condition exists which with notice and the expiration of any grace
period would constitute an Event of Default under this Lease at the time the
option may be exercised and at the time the Renewal Period commences, Landlord
grants Tenant options (the "Renewal Options") to extend this Lease with respect
to all of the Premises for two additional consecutive periods of five years
(each a "Renewal Period"). The first Renewal Option shall be exercised by Tenant
delivering written notice to Landlord at least 9 months prior to the Expiration
Date of the initial Term, and provided that Tenant has exercised the first
Renewal Option, the second Renewal Option may be exercised by Tenant delivering
written notice to Landlord at least 9 months prior to the Expiration Date of the
Term of the first Renewal Period.

         10.16.2 The rate of annual Base Rent (the "Renewal Rental Rate") for
each Renewal Period shall be the market rental rate, which shall be the rental
rate then being charged by landlords (including Landlord) in the metropolitan
area in which the Premises is located on new leases or on renewed leases to
tenants of a similar credit quality to Tenant for space of similar quality and
size as the Premises, but in no event shall the Renewal Rental Rate be less than
the Base Rent in effect for the last Lease Year of the initial Term.

         10.16.3 Within fifteen days after Tenant's exercise of each Renewal
Option, Landlord shall notify Tenant in writing of Landlord's proposed Renewal
Rental Rate as determined by the above formula. Tenant shall have ten days from
the receipt of Landlord's notice to either accept or dispute Landlord's
determination of the Renewal Rental Rate. In the event that Tenant disputes
Landlord's determination, Tenant shall so notify Landlord and advise Landlord of
Tenant's determination of the Renewal Rental Rate for the Renewal Period as
determined by the above formula. If Landlord and Tenant cannot agree upon the
Renewal Rental Rate within thirty days of Tenant's original notice of its intent
to exercise its Renewal Option, the following "Dispute Resolution Mechanism"
shall be utilized: The parties, within ten days after the expiration of said
thirty day period, shall jointly appoint as arbitrator, a certified commercial
real estate appraiser with a minimum of ten years experience in the applicable
market, employed by a major real estate firm operating in the Boulder, Colorado
area. If Landlord and Tenant cannot agree on an acceptable arbitrator, Landlord
and Tenant shall each choose, within an additional ten days thereafter, its own
arbitrator who meets the qualifications described above. The arbitrators shall
then



                                       23
<PAGE>   27


jointly select, within an additional ten days, an arbitrator to serve as the
arbitrator hereunder. Within twenty days after appointment, the arbitrator shall
choose either Landlord's or Tenant's determination of the Renewal Rental Rate.
The cost of the arbitrator(s) shall be borne by the party whose determination of
the Renewal Rental Rate was not selected by the arbitrator.

         10.16.4 Landlord and Tenant shall execute an amendment to this Lease
within fifteen days after the determination of the Renewal Rental Rate, which
amendment shall set forth the extended Term and the Renewal Rental Rate. Except
for any change in the rate of Base Rent, the Renewal Period shall be subject to
all of the terms and conditions of this Lease.

         10.16.5 Neither any option granted to Tenant to renew or extend the
Term, nor the exercise of any such option by Tenant, shall prevent Landlord from
exercising any option or right granted or reserved to Landlord in this Lease, or
that Landlord may otherwise have, to terminate this Lease or any renewal or
extension of the Term either during the original Term or during the renewed or
extended term. Any renewal or extension right granted to Tenant shall be
personal to Tenant and may not be exercised by any assignee, subtenant or legal
representative of Tenant. Any termination of this Lease shall serve to terminate
any such renewal or extension of the Term, whether or not Tenant shall have
exercised the option to renew or extend the Term. No option granted to Tenant to
renew or extend the Term shall be deemed to give Tenant any further option to
renew or extend.
