                                  TALLAN, INC.

                        2000 EMPLOYEE STOCK PURCHASE PLAN

ARTICLE 1 - PURPOSE.

      This 2000 Employee Stock Purchase Plan (the "Plan") is intended to
encourage stock ownership by all eligible employees of Tallan, Inc. (the
"Company"), a Delaware corporation, and its participating subsidiaries (as
defined in Article 17) so that they may share in the growth of the Company by
acquiring or increasing their proprietary interest in the Company. The Plan is
designed to encourage eligible employees to remain in the employ of the Company
and its participating subsidiaries. The Plan is intended to constitute an
"employee stock purchase plan" within the meaning of Section 423(b) of the
Internal Revenue Code of 1986, as amended (the "Code").

ARTICLE 2 - ADMINISTRATION OF THE PLAN.

      The Plan may be administered by a committee appointed by the Board of
Directors of the Company (the "Committee"). The Committee shall consist of not
less than two members of the Company's Board of Directors. The Board of
Directors may from time to time remove members from, or add members to, the
Committee. Vacancies on the Committee, howsoever caused, shall be filled by the
Board of Directors. The Committee may select one of its members as Chairman, and
shall hold meetings at such times and places as it may determine. Acts by a
majority of the Committee, or acts reduced to or approved in writing by a
majority of the members of the Committee, shall be the valid acts of the
Committee.

      The interpretation and construction by the Committee of any provisions of
the Plan or of any option granted under it shall be final, unless otherwise
determined by the Board of Directors. The Committee may from time to time adopt
such rules and regulations for carrying out the Plan as it may deem best,
provided that any such rules and regulations shall be applied on a uniform basis
to all employees under the Plan. No member of the Board of Directors or the
Committee shall be liable for any action or determination made in good faith
with respect to the Plan or any option granted under it.

      In the event the Board of Directors fails to appoint or refrains from
appointing a Committee, the Board of Directors shall have all power and
authority to administer the Plan. In such event, the word "Committee" wherever
used herein shall be deemed to mean the Board of Directors.

ARTICLE 3 - ELIGIBLE EMPLOYEES.

      All employees of the Company or any of its participating subsidiaries
shall be eligible to receive options under the Plan to purchase common stock of
the Company, and all eligible employees shall have the same rights and
privileges hereunder. Persons who are eligible employees on the first business
day of any Payment Period (as defined in Article 5) shall receive their options
as of such day. Persons who become eligible employees after any date on which
options are granted under the Plan shall be granted options on the first day of
the next succeeding Payment Period on which options are granted to eligible
employees under the Plan. In no event, however, may an employee be granted an
option if such employee, immediately after the option was granted, would be
treated as owning stock possessing five percent or more of the total combined
voting power or value of all classes of stock of the Company or of any parent
corporation or subsidiary corporation, as the terms "parent corporation" and
"subsidiary corporation" are defined in Section 424(e) and (f) of the Code. For
purposes of determining stock ownership under this paragraph, the rules of
Section 424(d) of the Code shall apply, and stock which the employee may
purchase under outstanding options shall be treated as stock owned by the
employee.

      For the purposes of this Article 3, the term "employee" shall mean an
employee whose customary employment is more than twenty (20) hours per week and
for more than five (5) months in any calendar year.

ARTICLE 4 - STOCK SUBJECT TO THE PLAN.

      The stock subject to the options under the Plan shall be shares of the
Company's authorized but unissued common stock, par value $.01 per share (the
"Common Stock"), or shares of Common Stock reacquired by the Company, including
shares purchased in the open market. The aggregate number of shares which may be
issued pursuant to the Plan is 1,200,000, subject to adjustment as provided in
Article 12. If any option granted under the Plan shall expire or terminate for
any reason without having been exercised in full or shall cease for any reason
to be exercisable in whole or in part, the unpurchased shares subject thereto
shall again be available under the Plan.

ARTICLE 5 - PAYMENT PERIOD AND STOCK OPTIONS.

      Payment Periods during which payroll deductions will be accumulated under
the Plan shall consist of the six-month periods from September 1 to the last day
of February and from March 1 to August 31 of each calendar year, beginning with
the first Payment Period. The first Payment Period under the Plan shall commence
on the effective date of an initial public offering of Common Stock of the
Company (the "Effective Date") and shall end on the following August
<PAGE>   3
                                      -3-

31st. Payroll deductions made from bonus and commission payments will be deemed
accumulated under the Plan during the Payment Period during which such payments
are made. All other payroll deductions will be deemed accumulated under the Plan
during the Payment Period during which the regular payroll period to which it
relates ends.

      Twice each year, on the first business day of each Payment Period, the
Company will grant to each eligible employee who is then a participant in the
Plan an option to purchase on the last day of such Payment Period, at the Option
Price hereinafter provided for, a maximum of 500 shares, on condition that such
employee remains eligible to participate in the Plan throughout the remainder of
such Payment Period. The participant shall be entitled to exercise the option so
granted only to the extent of the participant's accumulated payroll deductions
on the last day of such Payment Period. If the participant's accumulated payroll
deductions on the last day of the Payment Period would enable the participant to
purchase more than 500 shares except for the 500 share limitation, the excess of
the amount of the accumulated payroll deductions over the aggregate purchase
price of the 500 shares shall be promptly refunded to the participant by the
Company, without interest. The Option Price per share for each Payment Period
shall be the lesser of (i) 85% of the average market price of the Common Stock
on the first business day of the Payment Period and (ii) 85% of the average
market price of the Common Stock on the last business day of the Payment Period,
in either event rounded up to avoid fractions of a dollar other than 1/4, 1/2
and 3/4. The foregoing limitation on the number of shares subject to option and
the Option Price shall be subject to adjustment as provided in Article 12.

      For purposes of the Plan, the term "average market price" on any date
means (i) the average (on that date) of the high and low prices of the Common
Stock on the principal national securities exchange on which the Common Stock is
traded, if the Common Stock is then traded on a national securities exchange; or
(ii) the last reported sale price (on that date) of the Common Stock on the
Nasdaq National Market, if the Common Stock is not then traded on a national
securities exchange; or (iii) the average of the closing bid and asked prices
last quoted (on that date) by an established quotation service for
over-the-counter securities, if the Common Stock is not reported on the Nasdaq
National Market; or (iv) if the Common Stock is not publicly traded, the fair
market value of the Common Stock as determined by the Committee after taking
into consideration all factors which it deems appropriate, including, without
limitation, recent sale and offer prices of the Common Stock in private
transactions negotiated at arm's length.

      For purposes of the Plan, the term "business day" means a day on which
there is trading on the Nasdaq National Market or the aforementioned national
securities exchange, whichever is applicable pursuant to the preceding
paragraph; and if neither is applicable, a day that is not a Saturday, Sunday or
legal holiday in the State of Connecticut.
<PAGE>   4
                                      -4-

      No employee shall be granted an option which permits the employee's right
to purchase stock under the Plan, and under all other Section 423(b) employee
stock purchase plans of the Company and any parent or subsidiary corporations,
to accrue at a rate which exceeds $25,000 of fair market value of such stock
(determined on the date or dates that options on such stock were granted) for
each calendar year in which such option is outstanding at any time. The purpose
of the limitation in the preceding sentence is to comply with Section 423(b)(8)
of the Code. If the participant's accumulated payroll deductions on the last day
of the Payment Period would otherwise enable the participant to purchase Common
Stock in excess of the Section 423(b)(8) limitation described in this paragraph,
the excess of the amount of the accumulated payroll deductions over the
aggregate purchase price of the shares actually purchased shall be promptly
refunded to the participant by the Company, without interest.

ARTICLE 6 - EXERCISE OF OPTION.

      Each eligible employee who continues to be a participant in the Plan on
the last day of a Payment Period shall be deemed to have exercised his or her
option on such date and shall be deemed to have purchased from the Company such
number of full shares of Common Stock reserved for the purpose of the Plan as
the participant's accumulated payroll deductions on such date will pay for at
the Option Price, subject to the 500 share limit of the option and the Section
423(b)(8) limitation described in Article 5. If the individual is not a
participant on the last day of a Payment Period, the he or she shall not be
entitled to exercise his or her option. Only full shares of Common Stock may be
purchased under the Plan. Unused payroll deductions remaining in a participant's
account at the end of a Payment Period by reason of the inability to purchase a
fractional share shall be carried forward to the next Payment Period.

ARTICLE 7 - AUTHORIZATION FOR ENTERING THE PLAN.

      An employee may elect to enter the Plan by filling out, signing and
delivering to the Company an authorization:

            A. Stating the percentage to be deducted regularly from the
      employee's pay;

            B. Authorizing the purchase of stock for the employee in each
      Payment Period in accordance with the terms of the Plan; and

            C. Specifying the exact name or names in which stock purchased for
      the employee is to be issued as provided under Article 11 hereof.
<PAGE>   5
                                      -5-

Such authorization must be received by the Company at least ten days before the
first day of the next succeeding Payment Period and shall take effect only if
the employee is an eligible employee on the first business day of such Payment
Period.

      Unless a participant files a new authorization or withdraws from the Plan,
the deductions and purchases under the authorization the participant has on file
under the Plan will continue from one Payment Period to succeeding Payment
Periods as long as the Plan remains in effect.

      The Company will accumulate and hold for each participant's account the
amounts deducted from his or her pay. No interest will be paid on these amounts.

ARTICLE 8 - MAXIMUM AMOUNT OF PAYROLL DEDUCTIONS.

      An employee may authorize payroll deductions in an amount (expressed as a
whole percentage) not less than one percent (1%) but not more than ten percent
(10%) of the employee's total compensation, including base pay or salary and any
overtime, bonuses or commissions.

ARTICLE 9 - CHANGE IN PAYROLL DEDUCTIONS.

      Deductions may not be increased or decreased during a Payment Period.
However, a participant may withdraw in full from the Plan.

ARTICLE 10 - WITHDRAWAL FROM THE PLAN.

      A participant may withdraw from the Plan (in whole but not in part) at any
time prior to the last day of a Payment Period by delivering a withdrawal notice
to the Company.

      To re-enter the Plan, an employee who has previously withdrawn must file a
new authorization at least ten days before the first day of the next Payment
Period in which he or she wishes to participate. The employee's re-entry into
the Plan becomes effective at the beginning of such Payment Period, provided
that he or she is an eligible employee on the first business day of the Payment
Period.

ARTICLE 11 - ISSUANCE OF STOCK.

      Certificates for stock issued to participants shall be delivered as soon
as practicable after each Payment Period by the Company's transfer agent.

      Stock purchased under the Plan shall be issued only in the name of the
participant, or if the participant's authorization so specifies, in the name of
the participant and another person of legal age as joint tenants with rights of
survivorship.

                                      -6-

ARTICLE 12 - ADJUSTMENTS.

      Upon the happening of any of the following described events, a
participant's rights under options granted under the Plan shall be adjusted as
hereinafter provided:

              A. In the event that the shares of Common Stock shall be
      subdivided or combined into a greater or smaller number of shares or if,
      upon a reorganization, split-up, liquidation, recapitalization or the like
      of the Company, the shares of Common Stock shall be exchanged for other
      securities of the Company, each participant shall be entitled, subject to
      the conditions herein stated, to purchase such number of shares of Common
      Stock or amount of other securities of the Company as were exchangeable
      for the number of shares of Common Stock that such participant would have
      been entitled to purchase except for such action, and appropriate
      adjustments shall be made in the purchase price per share to reflect such
      subdivision, combination or exchange; and

              B. In the event the Company shall issue any of its shares as a
      stock dividend upon or with respect to the shares of stock of the class
      which shall at the time be subject to option hereunder, each participant
      upon exercising such an option shall be entitled to receive (for the
      purchase price paid upon such exercise) the shares as to which the
      participant is exercising his or her option and, in addition thereto (at
      no additional cost), such number of shares of the class or classes in
      which such stock dividend or dividends were declared or paid, and such
      amount of cash in lieu of fractional shares, as is equal to the number of
      shares thereof and the amount of cash in lieu of fractional shares,
      respectively, which the participant would have received if the participant
      had been the holder of the shares as to which the participant is
      exercising his or her option at all times between the date of the granting
      of such option and the date of its exercise.

      Upon the happening of any of the foregoing events, the class and aggregate
number of shares set forth in Article 4 hereof which are subject to options
which have been or may be granted under the Plan and the limitations set forth
in the second paragraph of Article 5 shall also be appropriately adjusted to
reflect the events specified in paragraphs A and B above. Notwithstanding the
foregoing, any adjustments made pursuant to paragraphs A or B shall be made only
after the Committee, based on advice of counsel for the Company, determines
whether such adjustments would constitute a "modification" (as that term is
defined in Section 424 of the Code). If the Committee determines that such
adjustments would constitute a modification, it may refrain from making such
adjustments.

      If the Company is to be consolidated with or acquired by another entity in
a merger, a sale of all or substantially all of the Company's assets or
otherwise (an "Acquisition"), the Committee or the board of directors of any
entity assuming the
<PAGE>   7
                                      -7-

obligations of the Company hereunder (the "Successor Board") shall, with respect
to options then outstanding under the Plan, either (i) make appropriate
provision for the continuation of such options by arranging for the substitution
on an equitable basis for the shares then subject to such options either (a) the
consideration payable with respect to the outstanding shares of the Common Stock
in connection with the Acquisition, (b) shares of stock of the successor
corporation, or a parent or subsidiary of such corporation, or (c) such other
securities as the Successor Board deems appropriate, the fair market value of
which shall not materially exceed the fair market value of the shares of Common
Stock subject to such options immediately preceding the Acquisition; or (ii)
terminate each participant's options in exchange for a cash payment equal to the
excess of (a) the fair market value on the date of the Acquisition, of the
number of shares of Common Stock that the participant's accumulated payroll
deductions as of the date of the Acquisition could purchase, at an option price
determined with reference only to the first business day of the applicable
Payment Period and subject to the 500 share limit, Code Section 423(b)(8) and
fractional-share limitations on the amount of stock a participant would be
entitled to purchase, over (b) the result of multiplying such number of shares
by such option price.

      The Committee or Successor Board shall determine the adjustments to be
made under this Article 12, and its determination shall be conclusive.

ARTICLE 13 - NO TRANSFER OR ASSIGNMENT OF EMPLOYEE'S RIGHTS.

      An option granted under the Plan may not be transferred or assigned and
may be exercised only by the participant.

ARTICLE 14 - TERMINATION OF EMPLOYEE'S RIGHTS.

      Whenever a participant ceases to be an eligible employee because of
retirement, voluntary or involuntary termination, resignation, layoff,
discharge, death or for any other reason, his or her rights under the Plan shall
immediately terminate, and the Company shall promptly refund, without interest,
the entire balance of his or her payroll deduction account under the Plan.
Notwithstanding the foregoing, eligible employment shall be treated as
continuing intact while a participant is on military leave, sick leave or other
bona fide leave of absence, for up to 90 days, or for so long as the
participant's right to re-employment is guaranteed either by statute or by
contract, if longer than 90 days. If a participant's payroll deductions are
interrupted by any legal process, a withdrawal notice will be considered as
having been received from the participant on the day the interruption occurs.

ARTICLE 15 - TERMINATION AND AMENDMENTS TO PLAN.

      Unless terminated sooner as provided below, the Plan shall terminate on
January 27, 2009. The Plan may be terminated at any time by the Company's Board
of Directors but
<PAGE>   8
                                      -8-

such termination shall not affect options then outstanding under the Plan. It
will terminate in any case when all or substantially all of the unissued shares
of stock reserved for the purposes of the Plan have been purchased. If at any
time shares of stock reserved for the purpose of the Plan remain available for
purchase but not in sufficient number to satisfy all then unfilled purchase
requirements, the available shares shall be apportioned among participants in
proportion to the amount of payroll deductions accumulated on behalf of each
participant that would otherwise be used to purchase stock, and the Plan shall
terminate. Upon such termination or any other termination of the Plan, all
payroll deductions not used to purchase stock will be refunded, without
interest.

      The Committee or the Board of Directors may from time to time adopt
amendments to the Plan provided that, without the approval of the stockholders
of the Company, no amendment may (i) increase the number of shares that may be
issued under the Plan; (ii) change the class of employees eligible to receive
options under the Plan, if such action would be treated as the adoption of a new
plan for purposes of Section 423(b) of the Code; or (iii) cause Rule 16b-3 under
the Securities Exchange Act of 1934 to become inapplicable to the Plan.

ARTICLE 16 - LIMITS ON SALE OF STOCK PURCHASED UNDER THE PLAN.

      The Plan is intended to provide shares of Common Stock for investment and
not for resale. The Company does not, however, intend to restrict or influence
any employee in the conduct of his or her own affairs. An employee may,
therefore, sell stock purchased under the Plan at any time the employee chooses,
subject to compliance with any applicable federal or state securities laws and
subject to any restrictions imposed under Article 21 to ensure that tax
withholding obligations are satisfied. THE EMPLOYEE ASSUMES THE RISK OF ANY
MARKET FLUCTUATIONS IN THE PRICE OF THE STOCK.

ARTICLE 17 - PARTICIPATING SUBSIDIARIES.

      The term "participating subsidiary" shall mean any present or future
subsidiary of the Company, as that term is defined in Section 424(f) of the
Code, which is designated from time to time by the Board of Directors to
participate in the Plan. The Board of Directors shall have the power to make
such designation before or after the Plan is approved by the stockholders.

ARTICLE 18 - OPTIONEES NOT STOCKHOLDERS.

      Neither the granting of an option to an employee nor the deductions from
his or her pay shall constitute such employee a stockholder of the shares
covered by an option until such shares have been actually purchased by the
employee.
<PAGE>   9
                                      -9-

ARTICLE 19 - APPLICATION OF FUNDS.

      The proceeds received by the Company from the sale of Common Stock
pursuant to options granted under the Plan will be used for general corporate
purposes.

ARTICLE 20 - NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.

      By electing to participate in the Plan, each participant agrees to notify
the Company in writing immediately after the participant transfers Common Stock
acquired under the Plan, if such transfer occurs within two years after the
first business day of the Payment Period in which such Common Stock was
acquired. Each participant further agrees to provide any information about such
a transfer as may be requested by the Company or any subsidiary corporation in
order to assist it in complying with the tax laws. Such dispositions generally
are treated as "disqualifying dispositions" under Sections 421 and 424 of the
Code, which have certain tax consequences to participants and to the Company and
its participating subsidiaries.

ARTICLE 21 - WITHHOLDING OF ADDITIONAL INCOME TAXES.

      By electing to participate in the Plan, each participant acknowledges that
the Company and its participating subsidiaries are required to withhold taxes
with respect to the amounts deducted from the participant's compensation and
accumulated for the benefit of the participant under the Plan, and each
participant agrees that the Company and its participating subsidiaries may
deduct additional amounts from the participant's compensation, when amounts are
added to the participant's account, used to purchase Common Stock or refunded,
in order to satisfy such withholding obligations. Each participant further
acknowledges that when Common Stock is purchased under the Plan the Company and
its participating subsidiaries may be required to withhold taxes with respect to
all or a portion of the difference between the fair market value of the Common
Stock purchased and its purchase price, and each participant agrees that such
taxes may be withheld from compensation otherwise payable to such participant.
It is intended that tax withholding will be accomplished in such a manner that
the full amount of payroll deductions elected by the participant under Article 7
will be used to purchase Common Stock. However, if amounts sufficient to satisfy
applicable tax withholding obligations have not been withheld from compensation
otherwise payable to any participant, then, notwithstanding any other provision
of the Plan, the Company may withhold such taxes from the participant's
accumulated payroll deductions and apply the net amount to the purchase of
Common Stock, unless the participant pays to the Company, prior to the exercise
date, an amount sufficient to satisfy such withholding obligations. Each
participant further acknowledges that the Company and its participating
subsidiaries may be required to withhold taxes in connection with the
disposition of stock acquired under the Plan and agrees that the Company or any
participating subsidiary may take whatever action it considers appropriate to
satisfy such withholding requirements, including deducting from compensation
otherwise
<PAGE>   10
                                      -10-

payable to such participant an amount sufficient to satisfy such withholding
requirements or conditioning any disposition of Common Stock by the participant
upon the payment to the Company or such subsidiary of an amount sufficient to
satisfy such withholding requirements.

ARTICLE 22 - GOVERNMENTAL REGULATIONS.

      The Company's obligation to sell and deliver shares of Common Stock under
the Plan is subject to the approval of any governmental authority required in
connection with the authorization, issuance or sale of such shares.

      Government regulations may impose reporting or other obligations on the
Company with respect to the Plan. For example, the Company may be required to
identify shares of Common Stock issued under the Plan on its stock ownership
records and send tax information statements to employees and former employees
who transfer title to such shares.

ARTICLE 23 - GOVERNING LAW.

      The validity and construction of the Plan shall be governed by the laws of
Delaware, without giving effect to the principles of conflicts of law thereof.

ARTICLE 24 - APPROVAL OF BOARD OF DIRECTORS AND STOCKHOLDERS OF THE COMPANY.

      The Plan was adopted by the Board of Directors on January 27, 2000 and was
approved by the stockholders of the Company on [_____ ___, 2000].<PAGE>   1

     2.   LEASE OF PREMISES AND TERM. Landlord hereby leases to Tenant, and
Tenant accepts the premises ("Premises"), having an address of 628 Hebron
Avenue, Suite 502, Town of Glastonbury, County of Hartford, State of
Connecticut, being described in the plan attached hereto as Exhibit "A" in the
Building for the Term commencing on the Commencement Date and ending on the

used by Tenant for the Use and no other purpose, subject to the agreements
herein contained. Within thirty (30) days after the Commencement Date (as

and Termination Dates of the initial Lease Term. This Notice of Lease shall be
conclusive as to the terms stated therein and may be recorded by Tenant, at
Tenant's sole cost and expense, on the land records of the Town of Glastonbury.
Tenant hereby agrees to execute a release and/or termination in recordable form
of the Notice of Lease upon the expiration or early termination of this Lease.

     3.   RENT. Tenant shall pay as rent hereunder the Total Base Rent plus the
Rent Adjustments, as hereinafter defined, plus all other sums herein required to
be paid to Landlord (collectively, the "Rent"), to Agent at Agent's Address or
to such other person or at such other place as Landlord may from time to time
direct in writing. Tenant shall pay to Landlord the Total Base Rent in equal
monthly installments in the amount of the Monthly Base Rental, in advance on or
before the first day of each month of the Term, and at the same rate for
fractions of a month if the Term shall begin on any day except the first day of
a calendar month or shall end on any day except the last day of a calendar
month. The Monthly Base Rental set forth in Section 1F hereof represents the
Monthly Base Rental for the first year of the Term commencing on the

The payment of Rent hereunder is independent of each and every other covenant
and agreement contained herein. All Rent shall be paid without any notice,
set-off or deduction whatsoever.

     If Landlord has not received Tenant's Rental payment by the fifth (5th) day

Section 26F hereof from the date due until paid.

     4.   BASE RENT ADJUSTMENT. In addition to the Total Base Rent, Tenant shall
pay, as part of Rent, the Rent Adjustments described in this Section 4 without

                    portion thereof during the Term.

               (ii) The term "Expenses" shall mean and include all reasonable
                    expenses paid or incurred by Landlord or its employees,

                    under the Building, appurtenances and personal property used

                    Expenses shall not include costs of alterations of the
                    premises of tenants of the Building, interest and principal
                    payments on mortgages, ground rental payments, real estate
                    brokerage and leasing commissions, advertising or
                    promotional expenditures, any expense for which Landlord is
                    reimbursed by another party or by any insurance company, the
                    cost of any services furnished to any other tenant in the
                    Building which Landlord does not generally make available to
                    all tenants in the Building, costs incurred as a result of a
                    violation by Landlord of any lease for the Building, costs
                    and disbursements, including attorney's fees, incurred in
                    connection with negotiations or disputes with tenants or
                    other occupants of the Building or associated with the
                    enforcement of any leases, costs incurred by Landlord in
                    renovating, decorating, painting or otherwise improving
                    vacant space or space for tenants other than Tenant, or
                    costs incurred by Landlord regarding compliance with
                    Environmental Laws (as defined in Section 28) or ADA (as
                    defined in Section 29). Notwithstanding any of the
                    foregoing, the cost of any capital improvements to the
                    Building which are intended to reduce Expenses or which are
                    required under any governmental laws, regulations or
                    ordinances which were not applicable to the Building or not
                    in effect at the time the Building was constructed shall be
                    included in Expenses provided, however, Landlord agrees that
                    only the amortized portion of the cost of such capital
                    improvement will be included in Expenses each year and
                    Landlord shall amortize such costs over the useful life of
                    such improvements. If the Building is not fully occupied
                    during all or a portion of any Calendar Year, then Landlord
                    may elect to make an appropriate adjustment of the Expenses
                    for such year employing sound accounting and management
                    principles to determine the amount of Expenses that would
                    have been paid or incurred by Landlord had the Building been
                    ninety-five percent (95%) occupied and the amount so
                    determined shall be the amount of Expenses attributable to
                    such Calendar Year. If any Project expense, though paid in
                    one Calendar Year, relates to more than one Calendar Year,
                    at the option of Landlord, such expenses may be
                    proportionately allocated among such related Calendar Years.

              (iii) The term "Rent Adjustments" shall mean all amounts owed by
                    Tenant as additional rent as defined in Subparagraph 4B
                    hereof.

                                       3
<PAGE>   7

               (iv) The term "Rent Adjustment Deposit" shall mean an amount
                    equal to the estimate of Rent Adjustments due for any
                    Calendar Year after 1998 as reasonably estimated by Landlord
                    from time to time during the Term. The Rent Adjustment
                    Deposit shall be payable by Tenant in equal monthly
                    installments in the same manner as and contemporaneously
                    with the pay merit of Total Base Rent on the first day of
                    each month of the Term beginning January 1, 1999.

               (v)  The term "Taxes" shall mean real estate taxes, assessments,
                    sewer rents, rates and charges, transit taxes, taxes based
                    upon the receipt of rent, and any other federal, state or
                    local governmental charge, general, special, ordinary or
                    extraordinary (but not including general income or franchise
                    taxes or any other taxes imposed upon or measured by income
                    or profits, unless the same shall be imposed in lieu of
                    Taxes as herein defined or unless same shall be specifically
                    imposed upon income derived from rents), which may now or
                    hereafter be levied or assessed against the Project or any
                    portion thereof which are payable in any Calendar Year
                    during the Term. In case of special taxes or assessments
                    which may be payable in installments, only the amount of
                    each installment and interest thereon required to be paid
                    during a calendar year shall be included in Taxes for that
                    year. Taxes shall also include any personal property taxes
                    (attributable to the year in which paid) imposed upon the
                    furniture, fixtures, machinery, equipment, apparatus,
                    systems and appurtenances used in connection with the
                    operation of the Building. In the event the Project is not
                    assessed as fully improved for any year, then Taxes shall be
                    adjusted to the taxes which would have been payable in such
                    Calendar Year if the assessment had been made on a fully
                    improved basis, based on Landlord's adjustment of the
                    "Taxes" for such year, employing sound management
                    principles. Taxes also include Landlord's reasonable costs
                    and expenses (including reasonable attorneys' fees) in
                    contesting or attempting to reduce any Taxes. Taxes shall be
                    reduced by any recovery or refund received of Taxes
                    previously paid by Landlord, provided such refund relates to
                    Taxes paid during the Term. Notwithstanding anything set
                    forth above to the contrary, if at any time the method of
                    taxation then prevailing shall be altered so that any new or
                    additional tax, assessment, levy, imposition or charge or
                    any part thereof shall be imposed upon Landlord in place of
                    or partly in place of any Taxes or contemplated increase
                    therein, or in addition to Taxes, and shall be measured by
                    or be based in whole or in part upon the Project, the rents
                    or other income therefrom or any leases of any pan thereof,
                    then all such new taxes, assessments, levies, impositions

                                       4
<PAGE>   8

                    or charges or part thereof, to the extent that they are so
                    measured or based, shall be included in Taxes.

               (vi) The term "Base Year Expenses" shall mean Expenses applicable
                    during the 1998 Calendar Year. If the Landlord elects to
                    "Gross-Up" expenses for any Calendar Year as provided in
                    Section 4(A)(ii) above, and if the Building is not fully
                    occupied during the 1998 Calendar Year, then Landlord shall
                    make an appropriate adjustment of the Expenses for the 1998
                    Calendar Year employing sound accounting and management
                    principles to determine the amount of Expenses that would
                    have been paid or incurred by Landlord had the Building been
                    ninety-five percent (95%) occupied and the amount so
                    determined shall be the amount of Expenses attributable to
                    the 1998 Calendar Year. Tenant shall not be entitled to any
                    credit or rebate in the event Expenses in any one (1) year
                    are lower than the Base Year Expenses.

              (vii) The term "Base Year Taxes" shall mean Taxes payable during
                    the 1998 Calendar Year. Tenant shall not be entitled to any
                    credit or rebate in the event Taxes in any one (1) year are
                    lower than Base Year Taxes.

           B.  The amount of Rent Adjustment shall be calculated as follows:

               (i)  Tenant shall pay to Landlord, during each Calendar Year (or
                    fraction thereof), Tenant's Proportion of the amount by
                    which the Expenses for each such Calendar Year exceed Base
                    Year Expenses.

               (ii) Tenant shall pay to Landlord, during each Calendar Year (or
                    fraction thereof), Tenant's Proportion of the amount by
                    which the Taxes for each such Calendar Year exceed Base Year
                    Taxes. The amount of Taxes attributable to a Calendar Year
                    shall be the amount payable during any such Calendar Year,
                    even though the assessment for such Taxes may be for a
                    different Calendar Year.

           C.  Landlord shall provide Tenant with the amount of the Rent
               Adjustment Deposit for the 1999 Calendar Year on or before
               January 1, 1999 and Tenant shall thereon pay same to Landlord in
               equal monthly installments commencing on January 1, 1999.

           D.  Landlord shall use reasonable efforts to deliver to Tenant a
               statement ("Adjustment Statement"), within one hundred and eighty
               (180) days after the expiration of each Calendar Year, showing in
               reasonable detail the following:

                                       5
<PAGE>   9

              (i)   Expenses and Taxes for the Calendar Year last ended;

              (ii)  The amount of Rent Adjustments due Landlord for the Calendar
                    Year last ended, less credits for Base Year Expenses, Base
                    Year Taxes and Rent Adjustment Deposits paid, if any; and

              (iii) The Rent Adjustment Deposit due in the current Calendar
                    Year.

          E.  Within thirty (30) days after Tenant's receipt of each Adjustment
     Statement, Tenant shall pay to Landlord;

              (i)   The amount of Rent Adjustments shown on said statement to be
                    due Landlord for the Calendar Year last ended, if any; plus

              (ii)  The amount which, when added to the Rent Adjustment Deposit
                    theretofore paid in the current Calendar Year, would provide
                    that Landlord has then received such portion of the Rent
                    Adjustment Deposit as would have theretofore been paid to
                    Landlord had Tenant paid on a monthly basis one-twelfth
                    (1/12) of the Rent Adjustment Deposit for the current
                    Calendar Year.

     Commencing on the first day of the first month after Tenant's receipt of
     each Adjustment Statement, and on the first day of each month thereafter
     until Tenant receives a more current Adjustment Statement, Tenant shall pay
     to Landlord one-twelfth (1/12) of the Rent Adjustment Deposit shown on said
     statement. During the last complete Calendar Year of the Term, Landlord may
     include in the Rent Adjustment Deposit its estimate of the Rent Adjustment
     which may not be finally determined until after the expiration of the Term.
     In no event will the Landlord's failure to deliver the Adjustment Statement
     to Tenant within the one hundred and eighty (180) day time period relieve
     Tenant of its obligation to pay the Rent Adjustments specified above.
     Tenant's obligation to pay the Rent Adjustments shall survive the
     expiration or sooner termination of the Term.

          F.  Tenant's payment of the Rent Adjustment Deposit for each Calendar
     Year shall be credited against the Rent Adjustments for such Calendar Year.
     All Rent Adjustment Deposits may be co-mingled and no interest shall be
     paid to Tenant thereon. If the Rent Adjustment Deposit paid by Tenant for
     any Calendar Year exceeds the Rent Adjustments for such Calendar Year, then
     Landlord shall give a credit to Tenant in an amount equal to such excess
     against the Rent Adjustments due for the next succeeding Calendar Year,
     except that if any such excess relates to the last Calendar Year of the
     Term, then Landlord shall refund such excess to Tenant within sixty (60)
     days following the Landlord's determination of the amount of the excess
     payment by Tenant, provided that all of the following have first occurred:

               (i)  The Term has expired or otherwise been terminated;

                                       6
<PAGE>   10

            (ii)  Tenant has vacated the Premises and removed all of its
                  property and improvements therefrom in accordance with this
                  Lease;

            (iii) Tenant has surrendered the Premises to Landlord in accordance
                  with this Lease; and

            (iv)  Tenant has paid all Total Base Rent and Rent Adjustments due
                  under this Lease and has fully performed and observed each
                  and every covenant and condition of this Lease required to be
                  performed or observed by Tenant.

      G.    Tenant or its representative shall have the right to examine
Landlord's books and records with respect to the items in the Adjustment
Statement during normal business hours at any time within one (1) year following
the furnishing by Landlord to Tenant of such Adjustment Statement. Unless Tenant
shall take written exception to any item within such six (6) month period after
the furnishing of the foregoing statement, such statement shall be considered as
final and accepted by Tenant. Any amount due to Landlord as shown on any such
statement, whether or not written exception is taken thereto, shall be paid by
Tenant within thirty (30) days after Landlord shall have submitted the

                  Tenant with Landlord's prior written consent, and warm water
                  for lavatory purposes from the regular supply of the Building.
                  Tenant shall pay Landlord at rates fixed by Landlord for water
                  furnished for any other purposes, and Landlord may install a
                  water meter at Tenant's sole cost to measure such usage.
                  Tenant shall not waste or permit the waste of water.

            (iii) Customary janitor service and cleaning in and about the
                  Premises Saturdays, Sundays and holidays excepted. Tenant
                  shall not provide any janitor services or cleaning without
                  Landlord's written consent, which consent shall not be
                  unreasonably withheld, and then only subject to supervision of
                  Landlord and at Tenant's sole responsibility.

            (iv)  Passenger elevator service in common with Landlord and other
                  tenants, daily from 8:00 A.M. to 6:00 P.M. Monday through

                  determined by Landlord, Saturdays, Sundays and holidays
                  excepted. Landlord shall provide limited passenger elevator
                  service daily at all times during which such normal passenger
                  service is not furnished. Operatorless automatic elevator
                  service shall be deemed "elevator service" within the meaning
                  of this paragraph.

            Landlord hereby agrees to use reasonable efforts to maintain the
Building and the Property in good order and repair reasonable wear and tear
excepted.

            B.    All electricity, telecommunication, signal and other similar
      services used in the Premises shall be supplied by utility companies
      serving the Building through a separate meter and the cost of said service
      is included in the Tenant's Monthly Base Rental payment. Landlord shall
      not in any way be liable or responsible to Tenant for any loss, damage or
      expense which Tenant may sustain or incur if either the quantity or
      character of such service is changed or is no longer available or suitable
      for Tenant's requirements. If such service be discontinued, such
      discontinuance shall not in any way affect this Lease or the liability of
      Tenant hereunder or cause a diminution of Base Rent or Rent Adjustments
      and the same shall not be deemed to be a lessening or diminution of
      services within the meaning of any law, rule or regulation now or
      hereafter enacted, promulgated or issued. Tenant shall receive such
      service directly from the utility companies and Landlord hereby permits
      its wires and conduits, to the extent available, suitable and safely
      capable, to be used for such purposes. Landlord agrees to use

                                       8
<PAGE>   12

      reasonable efforts to restore the services to the Premises as soon as
      reasonably possible provided, that, the restoration of the service is
      under the sole control of Landlord and that no third party is involved in
      restoring service to the Premises in any way. If a third party is involved
      in the restoration of the service, Landlord agrees to use reasonable
      efforts to encourage the third party to restore the service in a timely
      manner. For purposes of this Section, the term "reasonable efforts" shall
      not include the payment of money or the filing of any law suit.

            C.    Landlord does not warrant that any of the services above
      mentioned will be free from interruption caused by war, insurrection,
      civil commotion, riots, acts of God or the enemy, governmental action,
      repairs, renewals, improvements, alterations, strikes, lockouts,
      picketing, whether legal or illegal, accidents, inability of Landlord to
      obtain fuel, energy or supplies or any other cause or causes beyond the
      reasonable control of Landlord. No such interruption of service shall be
      deemed an eviction (or a constructive eviction) or disturbance of Tenant's
      use and possession of the Premises or any part thereof, or render Landlord
      liable to Tenant for damages, by abatement of Rent or otherwise, or
      relieve Tenant from performance of Tenant's obligations under this Lease.
      Tenant hereby waives and releases all claims against Landlord for damages
      from interruption or stoppage of service. Tenant agrees to cooperate fully
      with Landlord, at all times, in abiding by all regulations and
      requirements which Landlord may prescribe for the proper functioning and
      protection of all utilities and services reasonably necessary for the
      operation of the Project and the Building.

      6.    CONDITION OF PREMISES. Except for (i) the work to be completed by
Landlord as provided in Exhibit D "Landlord's Work" attached hereto and
incorporated herein by reference; (ii) heating air-conditioning, and electrical
facilities provided by Landlord to service the Premises; (iii) Landlord
obtaining a certificate of occupancy and delivering a copy thereof to Tenant;
and (iv) hidden and latent defects which are discovered by Tenant within the
initial six (6) months of the Term and reported to Landlord in writing within
such six (6) month period, Tenant's taking possession of the Premises, shall be
deemed to be Tenant's acceptance of the Premises, "As-Is, .... Where-Is," in the
order and condition as then exists. No promise of Landlord to alter, remodel,
decorate, clean or improve the Premises or the Building and no representation
respecting the condition of the Premises or the Building have been made by
Landlord to Tenant, unless the same is contained herein.

      7.    INABILITY TO DELIVER POSSESSION. If Landlord shall be unable to give
possession of the Premises on the Commencement Date for any reason other than as
a result of any act or omission on the part of Tenant, the Rent reserved and
covenanted to be paid herein shall not commence until the Premises are available
for occupancy by Tenant. No such failure to give possession on the Commencement
Date shall subject Landlord to any liability for failure to give possession nor
shall same affect the validity of this Lease or the obligation of Tenant
hereunder, nor shall the same be construed to extend the Term or Termination
Date. At the option of Landlord, to be exercised within thirty (30) days of the
delayed delivery of possession to Tenant, this Lease shall be amended so that
the Term shall be extended by the period of time possession is delayed. If the
Premises are ready for occupancy prior to the Commencement Date and Tenant
occupies the Premises prior to said date, Tenant shall pay proportionate Monthly
Base

                                       9
<PAGE>   13

Rental and Rent Adjustments. The Premises shall not be deemed to be unready for
Tenant's occupancy or incomplete if only minor or insubstantial details of
construction, decoration or mechanical adjustments remain to be done in the
Premises or any part thereof, or if the delay in the availability of the
Premises for occupancy shall be due to special work, changes, alterations or
additions required or made by Tenant in the layout or finish of the Premises, or
any part thereof or shall be caused in whole or in part by Tenant through the
delay of Tenant in submitting plans, supplying information, approving plans,
specifications or estimates, giving authorizations or shall be otherwise caused
in whole or in part by delay and/or default on the part of Tenant. In the event
of any dispute as to whether the Premises are ready for Tenant's occupancy, said
dispute shall be resolved by the mutual agreement of the architects representing
the Landlord and Tenant and this decision shall be final and binding on Landlord
and Tenant. In the event the architects representing the Landlord and Tenant can
not reach an agreement, then Landlord and Tenant shall mutually select an
independent architect with no less than ten (10) years experience designing
office spaces in the Glastonbury, Connecticut metropolitan area to resolve the
dispute. The decision of the independent architect shall be final and binding on
Landlord and Tenant. The cost of hiring the independent architect shall be
divided equally among the parties.

      8.    CARE AND MAINTENANCE. Subject to the provisions of Sections 13 and
14 hereof, Tenant shall, at Tenant's own expense, keep the Premises in good
order, condition and repair and shall pay for the repair of any damages caused
by Tenant, its agents, contractors, employees or invitees. Tenant shall promptly
arrange with Landlord, at Tenant's sole cost and expense, for the repair of all
damage to the Premises and the replacement or repair of all damaged or broken
glass (including signs thereof), fixtures and appurtenances (including hardware,
heating, cooling, ventilating, electrical, plumbing and other mechanical
facilities in the Premises), with materials equal in quality and class to the
original materials damaged or broken, within any reasonable period of time
specified by Landlord, all repairs and replacements to be made under the
supervision and with the prior written approval of Landlord, using contractors
or persons acceptable to Landlord. If Tenant does not promptly make such
arrangements, Landlord may, but need not, make such repairs and replacements
upon three (3) days prior notice to Tenant, and one hundred ten percent (110%)
of Landlord's cost for such repairs and replacements shall be deemed Additional
Rent reserved under this Lease due and payable forthwith. Tenant shall pay
Landlord or the managing agent of the Building, as Landlord may direct, a fee
for supervision and coordination of all work performed by Tenant as well as all
costs for overtime and for any other expense incurred in the event repairs,
alterations, decorating or other work in the Premises are not made during
ordinary business hours at Tenant's request. Notwithstanding the above, the
Landlord shall not impose a supervision fee on Tenant for any work performed by
the Tenant in the Premises which will cost less than Ten Thousand Dollars
($10,000.00) to perform.

      9.    ALTERATIONS.

            A. Tenant shall not do any painting or decorating, or erect any
      partitions, make any alterations in or additions to the Premises or do any
      nailing, boring or screwing into the ceilings, walls or floors, without
      Landlord's prior written consent in each and every instance, which consent
      will not be unreasonably withheld. Notwithstanding the above,

                                       10
<PAGE>   14

      Tenant shall be allowed to make alterations in or additions to the
      Premises, without the prior consent of Landlord, provided said alterations
      or additions do not require changes to, or in any way effect, any of the
      structural elements or mechanical systems of the Building and do not cost
      more than Ten Thousand and 00/100 Dollars ($10,000.00) per calendar year.
      Unless otherwise agreed by landlord and Tenant in writing, all such work
      shall be performed either by or under the direction of Landlord, but at
      the sole cost and expense of Tenant..Landlord's decision to refuse such
      consent shall be conclusive. If Landlord consents to such alterations or
      additions, before commencement of the work or delivery of any materials
      into the Premises or into the Building, Tenant shall furnish to Landlord
      for approval: (A)plans and specifications; (B) names and addresses of
      contractors; (C) copies of construction or other contracts; (D)all
      necessary permits; (E) evidence reasonably satisfactory to Landlord of
      Tenant's ability to pay for the cost of such alterations or additions
      provided, however, Tenant shall not be required to post any bond, letter
      of credit, or provide any other monetary deposit to Landlord unless the
      total cost of the proposed alterations equal or exceed Twenty-Five
      Thousand Dollars ($25,000.00); and (F) indemnification and insurance in
      form and amount satisfactory to Landlord from all contractors performing
      labor or furnishing materials, insuring against any and all claims, costs,
      damages, liabilities and expenses which may arise in connection with the
      alterations or additions.

            B. Within thirty (30) days following the Landlord's receipt of the
      plans and specifications for the proposed alterations, Landlord shall
      notify the Tenant of the Landlord's approval or disapproval of said plans.
      If Landlord does not communicate its approval or disapproval of said plans
      to the Tenant within the thirty (30) day period the plans and
      specifications shall be deemed to be approved by the Landlord. Landlord
      may withhold approval of any alterations or additions if the plans and
      specifications therefor are not acceptable to Landlord or Landlord's
      architect or engineer (if any). In connection with any request for
      approval of any alterations or additions by Tenant, Landlord may retain
      the services of an outside architect and/or engineer and the reasonable
      fees of such architect and/or engineer to Landlord shall be reimbursed to
      Landlord by Tenant upon demand. Landlord's approval of any plans or
      specifications shall not be construed to be an agreement or representation
      on Landlord's part as to the adequacy or suitability of Tenant's
      alterations or additions and creates no responsibility or liability on the
      part of Landlord for the compliance of such plans or specifications with
      statutes, laws, ordinances, orders, codes, rules and regulations of
      governmental authorities.

            C. In the event Landlord permits the alterations or additions to be
      completed by Tenant's contractor, Landlord reserves the right to require
      that Tenant terminate its contract with any such contractor in the event
      said contractor is engaged in a labor dispute which disrupts said
      contractor's work. Landlord shall also have the right to order any
      contractor of Tenant who violates any of Landlord's requirements or
      standards of work to cease work and to remove himself, his equipment and
      his employees from the Building. Landlord or the managing agent of the
      Building shall be entitled to charge a fee for supervision and
      coordination of all such alterations which require Landlord's consent.
      Tenant agrees that its contractors shall not conduct their work in such a
      manner

                                       11
<PAGE>   15

      so as to interfere with or cause any interruption of either: (A)
      Landlord's construction; (B) another tenant's occupancy or construction;
      or (C) other phases of Landlord's operation of the Building.

            D. Whether Tenant furnishes Landlord the foregoing or not, Tenant
      hereby agrees to indemnify and hold Landlord, its trustees, partners and
      their respective agents and employees harmless from any and all
      liabilities of every kind and description which may arise out of or be
      connected in any way with said alterations or additions. Any mechanic's
      lien filed against the Premises or the Building for work claimed to have
      been furnished to Tenant shall be discharged of record by Tenant within
      thirty (30) days thereafter, at Tenant's sole cost and expense. Upon
      completing any alterations or additions, Tenant shall furnish Landlord
      with contractors' affidavits and full and final waivers of lien and
      receipted bills covering all labor and materials expended and used. All
      alterations and additions shall comply with all insurance requirements and
      with all ordinances and regulations of any pertinent governmental
      authority. All alterations and additions shall be constructed in a good
      and workmanlike manner and only high grades of materials shall be used.

            E. All additions, decorations, fixtures, hardware, wires, pipes,
      conduit, non-trade fixtures and all improvements, temporary or permanent,
      in or upon the Premises, whether placed there by Tenant or by Landlord,
      shall, unless Landlord requests their removal, become Landlord's property
      and shall remain upon the Premises at the termination of this Lease, by
      lapse of time or otherwise, without compensation, allowance or credit to
      Tenant. Landlord may, at its sole option, request Tenant, at Tenant's sole
      cost and expense, to remove same and if, upon Landlord's request, Tenant
      does not remove said additions, decorations, fixtures, hardware, non-trade
      fixtures and improvements, Landlord may remove the same, and Tenant shall
      pay the cost of such removal to Landlord upon demand. Notwithstanding the
      above, Landlord agrees that the Tenant will not be required to remove any
      permanent addition, fixture, improvement, etc. unless Landlord requests
      the removal of such items at the time Landlord approves the installation
      of said items. If Tenant is not required or fails to obtain the Landlord's
      consent for the installation of any item, Landlord shall have the right to
      require the Tenant to remove said item from the Premises upon notice to
      Tenant delivered no later than the date this Lease terminates, by lapse of
      time or otherwise.

      10.   ACCESS TO PREMISES. Tenant shall permit Landlord, its employees,
contractors, agents and designees to erect, use and maintain pipes, ducts,
wiring and conduits in and through the Premises and to have free access to the
Premises and any part thereof in the event of an emergency. Landlord or
Landlord's agents, employees and contractors shall have the right to enter upon
the Premises to inspect the same, to perform janitorial and cleaning services
and to make such decorations, repairs, alterations, improvements or additions to
the Premises or the Project as Landlord may deem necessary or desirable, and
Landlord shall be allowed to take all material into and upon the Premises that
may be required thereof without the same constituting an eviction of Tenant in
whole or in part, and the Rent reserved shall in no way abate (except as
provided in Sections 13 or 14 hereof) while said decorations, repairs,
alterations, improvements or additions are being made, by reason of loss or
interruption of business of Tenant, or

                                       12
<PAGE>   16

otherwise. In an emergency situation, if Tenant shall not be personally present
to open and permit an entry into the Premises Landlord or Landlord's agents or
employees may enter the same by a master key, or may forcibly enter the same,
without rendering Landlord or such agents or employees liable therefor (if
during such entry Landlord or Landlord's agents or employees shall accord
reasonable care to Tenant's property), and without in any manner affecting the
obligations and covenants of this Lease. Nothing herein contained, however,
shall be deemed or construed to impose upon landlord any obligations,
responsibility or liability whatsoever for the care, supervision or repair of
the Building or any part thereof, in the exercise of any rights herein provided.
Landlord shall also have the right at any time without the same constituting an
actual or constructive eviction and without incurring any liability to Tenant
therefor, to change the arrangement and/or location of entrances or passageways,
doors and doorways, and corridors, elevators, stairs, toilets or public parts of
the Building, and to close entrances, doors, corridors, elevators or other
facilities. Landlord shall not be liable to Tenant for any expense, injury, loss
or damage resulting from work done in or upon, or the use of, any adjacent or
nearby building, land, street or alley. In connection with the Landlord's
entering the Premises to exercise any of the foregoing rights, Landlord shall
take reasonable steps to minimize any interference with Tenant's business
operations in the Premises.

      11.   INSURANCE. Tenant shall carry insurance during the entire Term
hereof insuring Tenant, and insuring, as additional named insureds, Landlord
(including any partners thereof), any trustee of Landlord, the managing agent
for the Project and their respective agents, partners and employees, as their
respective interests may appear, with terms, coverages and in companies
satisfactory to Landlord, and with such increases in limits as Landlord may from
time to time request, but initially Tenant shall maintain the following
coverages in the following amounts:

            A. Commercial general liability insurance, including the broad or
      extended liability endorsement, during the Term with terms and in
      companies reasonably satisfactory to Landlord to afford protection to the
      limits of not less than Two Million Dollars ($2,000,000) for combined
      single limit personal injury and property damage liability per occurrence.

            B. Insurance against fire, sprinkler leakage, vandalism, and the
      extended coverage perils for the full insurable value on an "All Risk",
      basis of all additions, improvements and alterations to the Premises, and
      of all office furniture, trade fixtures, office equipment, merchandise and
      all other items of Tenant's property on the Premises.

            C. Business interruption insurance insuring Tenant's payment of Rent
      for not less than a twelve (12) month period.

            D. Workers compensation insurance in statutory amounts and employers
      liability insurance in an amount not less than Five Hundred Thousand
      Dollars ($500,000).

            E. Tenant shall, prior to the Commencement Date and throughout the
      Term not less than thirty (30) days prior to the expiration of Tenant's
      policies of insurance, furnish to Landlord evidence of such coverage (on
      Accord Form 27), together with copies of the

                                       13
<PAGE>   17

      underlying policies, which shall state that such insurance coverage may
      not be changed or cancelled without at least thirty (30) days' prior
      written notice to Landlord and Tenant.

Landlord agrees to keep in force and effect casualty insurance on the Building
in amounts customarily maintained for office buildings located in the
Glastonbury, Connecticut metropolitan area. The cost of said insurance shall be
included in Expenses.

      12.   SUBROGATION. Landlord and Tenant agree to have all fire and extended
coverage and material damage insurance which may be carried by either of them
endorsed with a clause providing that any release from liability of or waiver of
claim for recovery from the other party or any of the parties named in Paragraph
11 above entered into in writing by the insured thereunder prior to any loss or
damage shall not affect the validity of said policy or the right of the insured
to recover thereunder, and providing further that the insurer waives all rights
of subrogation which such insurer might have against the other party or any of
the parties named in Paragraph 11 above. Without limiting any release or waiver
of liability or recovery contained in any Section of this Lease but rather in
confirmation and furtherance thereof, Landlord and any trustees of landlord
waive all claims for recovery from Tenant, and Tenant waives all claims for
recovery from Landlord, any trustees of Landlord and the managing agent for the
Project and their respective agents, partners and employees, for any loss or
damage to any of its property insured under valid and collectible insurance
policies to the extent of any recovery collectible under such insurance
policies.

      Notwithstanding the foregoing or anything contained in this Lease to the
contrary, any release or any waiver of claims shall not be operative, nor shall
the foregoing endorsements be required, in any case where the effect of such
release or waiver is to invalidate insurance coverage or invalidate the right of
the insured to recover thereunder or increase the cost thereof (provided that in
the case of increased cost, either party shall have the right, within ten (10)
days following written notice, to pay such increased cost, thereby keeping such
release or waiver in full force and effect).

      13.   UNTENANTABILITY. If all or substantially all of the Premises or in
excess of thirty percent (30%) of the Building are made untenantable by fire or
other casualty, Landlord may, at its option, elect:

            A. To terminate this Lease as of the date of the fire or casualty by
      notice to Tenant within sixty (60) days after that date; or

            B. To repair, restore or rehabilitate the Building or the Premises
      (excluding leasehold improvements, fixtures and personal property paid for
      by Tenant) at Landlord's expense, in which event this Lease shall not
      terminate.

      If less than thirty percent (30%) of the Building or less than
substantially all of the Premises are made untenantable by fire or other
casualty, then (so long as there are more than twelve (12) months remaining in
the Term) Landlord shall proceed with reasonable promptness to repair, restore
or rehabilitate the Building and/or the Premises, as the case may be, at

                                       14
<PAGE>   18

Landlord's expense. If less than thirty percent (30%) of the Building or less
than all or substantially all of the Premises are made untenantable as aforesaid
during the last year of the Term hereof, Landlord shall have the right to
terminate this Lease as of the date of such fire or other casualty by giving
written notice thereof to Tenant within sixty (60) days after the date of fire
or other casualty, in which event the Rent shall be apportioned on a per diem
basis and be paid to the date of such fire or other casualty.

      If the Premises are not rebuilt and restored within one hundred eighty
(180) days after the date of the casualty, Landlord, within five (5) days of
Tenant's written demand, shall provide Tenant with Landlord's estimate of the
time period to complete the restoration of the Premises. If the Premises are not
rebuilt and restored within such one hundred eighty (180) day period and
thereafter within thirty (30) days after Tenant's demand or Landlord advises
Tenant that the Premises will not be rebuilt and restored within such one
hundred eighty (180) day period and thereafter within thirty (30) days after
receipt of the demand therefor, then either Landlord or Tenant may, within ten
(10) days after Landlord's response to Tenant or expiration of such thirty (30)
day period, terminate this Lease upon written notice to the other party. The
Lease shall terminate on the date stated in such notice of termination.

      If, during the last year of the Lease Term, a casualty occurs which causes
all or substantially all of the Premises to be untenantable and as a result of
said casualty Tenant does not use any portion of the Premises, Tenant shall have
the right to terminate this Lease as of the date of such fire or other casualty
by giving written notice thereof to Landlord within thirty (30) days after the
date of fire or other casualty, in which event the Rent shall be apportioned on
a per diem basis and be paid to the date of such fire or other casualty.

      Landlord shall be under no obligation to expend for repair, restoration or
rehabilitation any amounts in excess of insurance proceeds paid to Landlord in
connection with such fire or other casualty and available for such repair,
restoration or rehabilitation.

      In the event the Lease is not terminated pursuant to these provisions,
Rent shall abate only with respect to any portion of the Premises rendered
untenantable on a per diem basis during the period of untenantability. In the
event of the termination of this Lease pursuant to this Section, Rent shall be
apportioned on a per diem basis and be paid to the date of the fire or other
casualty.

      14.   EMINENT DOMAIN.

            A. If a portion of the Building or the Premises, shall be lawfully
      taken or condemned for any public or quasi-public use or purpose, or
      conveyed under threat of such condemnation, and as a result thereof, the
      Premises cannot be used for the same purpose and with the same utility as
      before such taking or conveyance, the Term shall end upon, and not before,
      the date of the taking of possession by the condemning authority, and
      without apportionment of the award. Tenant hereby assigns to Landlord
      Tenant's interest in such award, if any. Current Rent shall be apportioned
      as of the date of such termination. If any part of the Building shall be
      so taken or condemned, or if the grade of any street or alley adjacent to
      the Building is changed by any competent

                                       15
<PAGE>   19

      authority and such taking or change of grade makes it necessary or
      desirable to demolish, substantially remodel, or restore the Building,
      Landlord shall have the fight to cancel this Lease upon not less than
      ninety (90) days' prior notice to Tenant.

            B. If a portion of the Premises shall be lawfully taken or condemned
      or conveyed under threat of condemnation, but thereafter the Premises can
      be used by Tenant for the same purpose and with substantially the same
      utility, in Tenant's reasonable business judgement, this Lease shall not
      be terminated and Landlord shall repair the Premises, and this Lease shall
      be amended to adjust Tenant's Proportion and Monthly Base Rental on the
      basis of the number of rentable square feet remaining in the Premises.

            C. No money or other consideration shall be payable by Landlord to
      Tenant for any right of cancellation or temporary taking, and Tenant shall
      have no right to share in the condemnation award, whether for a partial or
      total taking, for loss of Tenant's leasehold or improvements, and Tenant
      shall have no right to share in any judgment for damages caused by a
      change of grade. Notwithstanding the above, the Tenant shall have the
      right to pursue and retain a claim for moving expenses, the taking of
      Tenant's trade fixtures and such other business losses as Tenant can
      separately and specifically establish provided, that, any award to Tenant
      shall not diminish, in any way, the award available to the Landlord or its
      lender(s).

      15.   WAIVER OF CLAIMS AND INDEMNITY. To the extent permitted by law,
Tenant releases Landlord, its trustees, and their respective agents, employees,
mortgagees and partners (all of said parties are, for the purposes of this
Section 15 collectively referred to as "indemnitees") from, and waives all
claims for, damage to person or property sustained by Tenant or any occupant of
the Building or Premises resulting from the Building or Premises or any part of
either or any equipment or appurtenance becoming out of repair, or resulting
from any accident in or about the Building, or resulting directly or indirectly,
from any act or neglect of any tenant or occupant of the Building or of any
other person, including the indemnitees. This Paragraph 15 shall apply
especially, but not exclusively, to the flooding of basements or other
subsurface areas, and to damage caused by refrigerators, sprinkling devices,
air-conditioning apparatus, water, snow, frost, steam, excessive heat or cold,
falling plaster, broken glass, sewage, gas, odors or noise, or the bursting or
leaking of pipes, or plumbing fixtures, and shall apply equally whether any such
damage results from the act or neglect of other tenants, occupants or servants
in the Building or of any other person, and whether such damage be caused or
result from any thing or circumstance above mentioned or referred to, or any
other thing or circumstance whether of a like nature or of a wholly different
nature, except if caused by Landlord's gross negligence or willful misconduct.
If any such damage, whether to the Premises or to the Building or any part
thereof, or whether to Landlord or to other tenants in the Building, results
from any act or neglect of Tenant, its employees, agents, invitees and
customers, Tenant shall be liable therefor and Landlord may, at Landlord's
option, repair such damage and Tenant shall, upon demand by Landlord, reimburse
Landlord forthwith for the total cost of such repairs. Tenant shall not be
liable for any damage caused by its act or neglect to the extent Landlord or a
tenant has recovered the full amount of the damage from insurance and the
insurance company has waived its right of subrogation against Tenant. All
property

                                       16
<PAGE>   20

belonging to Tenant or any occupant of the Premises that is in the Building or
the Premises shall be there at the risk of Tenant or other person only, and
Landlord shall not be liable for damage thereto or theft or misappropriation
thereof.

      To the extent permitted by law, Tenant agrees to indemnify and save the
indemnitees harmless against any and all claims, demands, costs and expenses,
including reasonable attorney's fees for the defense thereof, arising from
Tenant's occupation of the Premises or from any breach or default on the part of
Tenant in the performance of any covenant or agreement on the part of Tenant to
be performed pursuant to the terms of this Lease, or from any act or negligence
of Tenant, its agents, servants, employees or invitees, in or about the
Premises. In case of any action or proceeding brought against any indemnitees by
reason of any such claim, upon notice from Landlord, Tenant covenants to defend
such action or proceeding by counsel reasonably satisfactory to Landlord.

      To the extent permitted by law, Landlord agrees to indemnify and save
Tenant harmless against any and all claims, demands, costs and expenses,
including reasonable attorney's fees for the defense thereof, arising from
Landlord's operation and maintenance of those areas of the Building which are
not leased to tenants of the Building. In case of any action or proceeding
brought against Tenant by reason of any such claim, upon notice from Tenant,
Landlord covenants to defend such action or proceeding.

      16.   ASSIGNMENT/SUBLETTING.

            A. Tenant shall not, without Landlord's prior written consent, which
      in each instance, shall not be unreasonably withheld: (i) assign,
      transfer, hypothecate, mortgage, encumber, or convey or subject to or
      permit to exist upon or be subjected to any lien or charge this Lease or
      any interest under it; (ii) allow any transfer of, or any lien upon,
      Tenant's interest in this Lease by operation of law; (iii) sublet the
      Premises in whole or in part; or (iv) allow the use or occupancy of any
      portion of the Premises for a use other than the Use or by anyone other
      than Tenant or Tenant's employees.

            Notwithstanding the foregoing, should any law governing Landlord's
      consent to a sublease or assignment require Landlord to exercise reason in
      the consideration of the granting or denying of consent, Landlord may take
      into consideration the business reputation and credit worthiness of the
      proposed subtenant or assignee; any alterations of the Premises; the
      intended use of the Premises by the proposed subtenant or assignee and any
      alterations to the Premises or Building which might be required as a
      result of such use; the estimated pedestrian and vehicular traffic in the
      Premises and to the Building which would be generated by the proposed
      subtenant or assignee; and any other factors which Landlord shall deem
      relevant. Provided further, however, that if Landlord does not consent to
      a sublease or assignment to any subtenant or assignee which is a
      governmental agency, which is a present tenant in the Building or with
      whom Landlord or its agents has discussed tenancy within the Building,
      same shall not be deemed to be unreasonable.

                                       17
<PAGE>   21

            Notwithstanding anything contained in this Section 16 to the
      contrary, Tenant may, without Landlord's prior consent, assign this Lease
      (i) to an entity with which Tenant is merging or consolidating, (ii) to
      its parent, (iii) to any wholly-owned subsidiary corporation of Tenant,
      (iv) to an affiliate of Tenant, or (v) to any entity acquiring all or
      substantially all of the Tenant's assets or stock provided the following
      conditions are met:

                  (i)   Tenant is not in default of the Lease at the time of the
                        assignment;

                  (ii)  Tenant shall have given Landlord thirty (30) days prior
                        written notice of such assignment;

                  (iii) The net worth of the assignee is reasonably acceptable
                        to the Landlord; and

                  (iv)  The assignee furnishes to Landlord, at least thirty (30)
                        days prior to the effective date of said assignment, a
                        written instrument satisfactory to Landlord in which
                        assignee agrees to assume and be bound by all the
                        conditions, obligations and agreements contained in this
                        Lease.

            Notwithstanding any such assignment the Tenant shall remain fully
      and primarily liable for the performance of all conditions, obligations,
      and agreements of Tenant under this Lease.

            B. If Tenant shall, with Landlord's prior consent as herein
      required, sublet the Premises, any amount received by Tenant in excess of
      the Monthly Base Rental and any Additional Rent herein provided to be paid
      shall be for the sole benefit of Landlord and shall be paid to Landlord
      promptly when due under any such subletting as Additional Rent.

            C. If Tenant is an entity whose ownership is not publicly held, and
      if during the Term, the ownership of the control of Tenant changes, Tenant
      shall notify Landlord of such change within five (5) days thereof, and
      Landlord, at its option, may at any time thereafter terminate this Lease
      by giving Tenant written notice of said termination at least sixty (60)
      days prior to the date of termination stated in the notice. The term
      "control" as used herein means the power to directly or indirectly direct
      or cause the direction of the management or policies of Tenant. A change
      or series of changes in ownership of stock which would result in direct or
      indirect change in ownership by the stockholders or an affiliated group of
      stockholders of less than fifty percent (50%) of the outstanding stock
      shall not be considered a change of control.

            D. Tenant shall, by notice in writing, advise Landlord of its
      intention from, on and after a stated date (which shall not be less than
      sixty (60) days after the date of the giving of Tenant's notice to
      Landlord) to assign this Lease or sublet any part or all of the Premises,
      and, in such event, Landlord shall have the right, to be exercised by
      giving written notice to Tenant within thirty (30) days after receipt of
      Tenant's notice, to

                                       18
<PAGE>   22

      terminate this Lease with respect to the space described in Tenant's
      notice as of the date stated in Tenant's notice for the commencement of
      the proposed assignment or sublease. Tenant's notice shall include the
      name and address of the proposed assignee or subtenant, a true and
      complete copy of the proposed assignment or sublease and sufficient
      information as Landlord deems necessary to permit Landlord to determine
      the financial responsibility and character of the proposed assignee or
      subtenant. If Tenant's notice covers all of the Premises and if Landlord
      exercises its right to terminate this Lease as to such space, then the
      Term of this Lease shall expire and end on the date stated in Tenant's
      notice for the commencement of the proposed assignment or sublease. If,
      however, Tenant's notice covers less than all of the Premises, and if
      Landlord exercises its right to terminate this Lease with respect to such
      space described in Tenant's notice, then as of the date stated in Tenant's
      notice for the commencement of the proposed sublease, the Monthly Base
      Rental and Tenant's Proportion shall be adjusted on the basis of the
      number of rentable square feet retained by Tenant, and this Lease as so
      amended, shall continue thereafter in full force and effect.

            E. Landlord's consent to any assignment or subletting shall not
      release Tenant from liability under this Lease or permit any subsequent
      prohibited act, unless specifically provided in such written consent.
      Tenant agrees to pay to Landlord, on demand, all reasonable costs incurred
      by Landlord in connection with any request by Tenant of Landlord in
      connection with any consent to any assignment or subletting by Tenant in
      addition to any fee imposed by Landlord as a condition to granting its
      consent.

      17.   SUBORDINATION. Landlord may execute and deliver a mortgage or trust
deed in the nature of a mortgage (both sometimes hereinafter referred to as
"Mortgage") against the Building, the Project or any interest therein, including
a ground lease thereof ("Ground Lease") and sell and Leaseback the underlying
land. This Lease and the rights of Tenant hereunder shall be and are hereby made
expressly subject and subordinate at all times to any Ground Lease of the land
or the Building, or both, now or hereafter existing and all amendments, renewals
and modifications thereto and extensions thereof, and to the lien of any
Mortgage now or hereafter encumbering any portion of the Project, and to all
advances made or hereafter to be made upon the security thereof; provided that
any such subordination at all times shall be subject to the right of Tenant to
remain in possession of the Premises, under the terms of this Lease for the
Term, notwithstanding any default under the Ground Lease or Mortgage or after
termination of said Ground Lease or foreclosure of the Mortgage or any sale
pursuant thereto so long as Tenant is not in default under this Lease. Tenant
agrees to execute and deliver such instruments subordinating this Lease to any
such Ground Lease and to the lien of any such Mortgage as may be requested in
writing by Landlord from time to time; provided, however, such subordination
shall be self-operative without the execution and delivery by Tenant of such
instruments. Notwithstanding anything to the contrary contained herein, any
mortgagee under a Mortgage may, by notice in writing to Tenant, subordinate its
Mortgage to this Lease. Landlord agrees to use reasonable efforts to obtain a
nondisturbance agreement from any future mortgage lender provided, however,
Tenant shall pay any and all costs incurred by Landlord to obtain said
nondisturbance agreement.

                                       19
<PAGE>   23

      In the event of the cancellation or termination of any such Ground Lease
described above in accordance with its terms or by the surrender thereof,
whether voluntary, involuntary or by operation of law, or by summary
proceedings, or the foreclosure of any such Mortgage by voluntary agreement or
otherwise, or the commencement of any judicial action seeking such foreclosure,
Tenant, at the request of the then Landlord, shall attorn to and recognize such
ground lessor, mortgagee or purchaser in foreclosure as Tenant's Landlord under
this Lease. Tenant agrees to execute and deliver at any time upon request of
such ground lessor, mortgagee, purchaser, or their successors, any instrument to
further evidence such attornment.

      Tenant agrees to give the holder of any Mortgage, by registered or
certified mail, a copy of any notice of default served upon Landlord by Tenant,
provided that prior to such notice Tenant has received notice (by way of service
of assignment of rents and leases, or otherwise) of the address of such
mortgagees and containing a request therefor. Tenant further agrees that if
Landlord shall have failed to cure such default within the time provided for in
this Lease, then said Mortgagees shall have an additional thirty (30) days after
receipt of notice thereof within which to cure such default or, if such default
cannot be cured within that time, then such additional time as may be necessary,
if, within such thirty (30) days, any mortgagee has commenced and is diligently
pursuing the remedies necessary to cure such default (including but not limited
to commencement of foreclosure proceedings, if necessary to effect such cure).
Such period of time shall be extended by any period within which such mortgagee
is prevented from commencing or pursuing such foreclosure proceedings by reason
of Landlord's bankruptcy. Until the time allowed as aforesaid for said mortgagee
to cure such defaults has expired without cure, Tenant shall have no right to,
and shall not, terminate this Lease on account of default. This Lease may not be
modified or amended so as to reduce the Rent or shorten the Term, or so as to
adversely affect in any other respect to any material extent the rights of
Landlord, nor shall this Lease be cancelled or surrendered, without the prior
written consent, in each instance, of the ground lessor or the mortgagee.

      18.   CERTAIN RIGHTS RESERVED TO LANDLORD. Landlord reserves and may
exercise the following rights without prior notice to Tenant and without
affecting Tenant's obligations hereunder:

            A. To change the name or street address of the Building provided,
      however, if Landlord changes the street address of the Building (excluding
      any change in the street address imposed or required by any governmental
      entity having jurisdiction over the property) Landlord agrees to reimburse
      Tenant for the actual costs incurred by Tenant to replace its existing
      letterhead, stationary and business cards but in no event, will the
      Landlord's reimbursement exceed a total of Five Hundred Dollars ($500.00).
      Any request for payment by Tenant, pursuant to this provision, must
      include a copy of the paid invoice for which Tenant is seeking
      reimbursement;

            B. To install and maintain a sign or signs on the interior or
      exterior of the Building;

                                       20
<PAGE>   24

            C. To have access for Landlord and the other tenants of the Building
      to any mail chutes located on the Premises according to the rules of the
      United States Postal Service;

            D. To designate all sources furnishing sign painting and lettering,
      ice, drinking water, towels, food, beverages, and toilet supplies, lamps
      and bulbs used on the Premises;

            E. To decorate, remodel, repair, alter or otherwise prepare the
      Premises for reoccupancy if Tenant vacates the Premises;

            F. To retain at all times pass keys to the Premises;

            G. To grant to anyone the exclusive right to conduct any particular
      business or undertaking in the Building;

            H. To exhibit the Premises to others during the last twelve (12)
      months of the Lease Term;

            I. To close the Building after regular working hours and on the
      holidays; subject, however, to Tenant's and its invitees' rights to
      admittance, under such reasonable regulations as Landlord may prescribe
      from time to time, which may include by way of example but not of
      limitation, that persons entering or leaving the Building identify
      themselves to a watchman by registration or otherwise and that said
      persons establish their right to enter or leave the Building; provided,
      however, Landlord shall not be liable for the failure to admit any person
      to the Building;

            J. To approve the weight, size and location of safes or other heavy
      equipment or articles, which articles may be moved in, about or out of the
      Building or Premises only at such times and in such manner as Landlord
      shall direct and in all events, however, at Tenant's sole risk and
      responsibility;

            K. To take any and all reasonable measures, including inspections,
      repairs, alterations, decorations, additions and improvements to the
      Premises or to the Building and to temporarily close public entry ways or
      other areas of the Building and interrupt or temporarily suspend any
      services or facilities, as may be necessary or desirable for the safety,
      protection or preservation of the Premises or the Building or Landlord's
      interests or the interest of other tenants, or as may be necessary or
      desirable in the operation of the Building. In connection with the
      Landlord's entering the Premises to exercise any of the foregoing rights,
      Landlord shall take reasonable steps to minimize any interference with
      Tenant's business operations in the Premises.

      Landlord may enter upon the Premises and may exercise any or all of the
foregoing rights reserved without being deemed guilty of an eviction or
disturbance of Tenant's use or possession and without being liable in any manner
to Tenant and without abatement of Rent or affecting any of Tenant's obligations
hereunder.

                                       21
<PAGE>   25

      19.   HOLDING OVER. If Tenant retains possession of the Premises or any
part thereof after the termination of the Term or any extension thereof, by
lapse of time and otherwise, Tenant shall pay Landlord Monthly Base Rental at
one hundred fifty percent (150%) multiplied by the rent, payable for the month
immediately preceding said holding over (plus increases for Rent Adjustments
which Landlord may reasonably estimate), computed on a per-month basis, for each
month or part thereof (without reduction for any such partial month) that Tenant
thus remains in possession, and in addition thereto, Tenant shall pay Landlord
all damages, consequential as well as direct, sustained by reason of Tenant's
retention of possession.

      20.   DEFAULT AND LANDLORD'S REMEDIES.

            A. Each of the following shall constitute a breach of this Lease by
      Tenant: (i) failure of Tenant to pay when due any monthly Rental
      installment; provided, however, that only in the case of the first two (2)
      such failures during each full calendar year of the term, if such payment
      is not made within five (5) days after written notice of such failure from
      Landlord; (ii) failure of Tenant to pay any monetary rental obligation
      other than monthly Rent within five (5) days after written notice of such
      failure from Landlord; (iii) Tenant fails to observe or perform any of the
      other covenants, conditions or provisions of this Lease to be observed or
      performed by Tenant and fails to cure such default within thirty (30) days
      after written notice thereof to Tenant; (iv) the interest of Tenant in
      this Lease is levied upon under execution or other legal process; (v) a
      petition is filed by or against Tenant to declare Tenant bankrupt or
      seeking a plan of reorganization or arrangement under any Chapter of the
      Bankruptcy Act, and said petition is not dismissed within sixty (60) days
      of filing, or any amendment, replacement or substitution therefor, or to
      delay payment of, reduce or modify Tenant's debts, or any petition is
      filed or other action taken to reorganize or modify Tenant's capital
      structure or upon the dissolution of Tenant, and said petition is not
      dismissed within sixty (60) days of filing; (vi) Tenant is declared
      insolvent by law or any assignment of Tenant's property is made for the
      benefit of creditors; (vi) a receiver is appointed for Tenant or Tenant's
      property; or (vii) Tenant abandons the Premises and ceases to pay Rent.

            B. In the event of any breach of this Lease by Tenant, Landlord at
      its option, without further notice or demand to Tenant, may, in addition
      to all other rights and remedies provided in this Lease, at law or in
      equity:

               (i)   Landlord may terminate this Lease by giving to Tenant
                     notice of Landlord's election to do so, in which event
                     the Term of this Lease shall end, and all right, title
                     and interest of Tenant hereunder shall expire, on the
                     date stated in such notice;

               (ii)  Landlord may terminate the right of Tenant to possession
                     of the Premises without terminating this Lease by giving
                     notice to Tenant that Tenant's right to possession shall
                     end on the date stated in such notice, whereupon the
                     right of

                                       22
<PAGE>   26

                        Tenant to possession of the Premises or any part thereof
                        shall cease on the date stated in such notice; and

                  (iii) Landlord may enforce the provisions of this Lease and
                        may enforce and protect the rights of Landlord hereunder
                        by a suit or suits in equity or at law for the specific
                        performance of any covenant or agreement contained
                        herein, or for the enforcement of any other appropriate
                        legal or equitable remedy, including recovery of all
                        moneys due or to become due from Tenant under any of the
                        provisions of this Lease.

            C. If Landlord exercises either of the remedies provided in
      Sections 20.B(i) or (ii), Tenant shall surrender possession and vacate the
      Premises and immediately deliver possession thereof to Landlord, and
      Landlord may re-enter and take complete and peaceful possession of the
      Premises in accordance with law.

            D. If Landlord terminates the right of Tenant to possession of the
      Premises without terminating this Lease, Landlord shall have the right to
      immediate recovery of all amounts then due hereunder. Such termination of
      possession shall not release Tenant, in whole or in part, from Tenant's
      obligation to pay Rent hereunder for the full Term, and Landlord shall
      have the right, from time to time, to recover from Tenant, and Tenant
      shall remain liable for, all Total Base Rent, Rent Adjustments and any
      other sums accruing as they become due under this Lease during the period
      from the date of such notice of termination of possession to the stated
      end of the Term. In any such case, Landlord may relet the Premises or any
      part thereof for the account of Tenant for such rent, for such time (which
      may be for a term extending beyond the Term of this Lease) and upon such
      terms as Landlord shall determine and may collect the rents from such
      reletting. Landlord shall not be required to accept any tenant offered by
      Tenant or to observe any instructions given by Tenant relative to such
      reletting. Also, in any such case, Landlord may make reasonable repairs,
      alterations and additions in or to the Premises and redecorate the same to
      the extent deemed by Landlord necessary or desirable and in connection
      therewith change the locks to the Premises, and Tenant upon demand shall
      pay the reasonable cost of all of the foregoing together with Landlord's
      reasonable expenses of reletting. The rents from any such reletting shall
      be applied first to the payment of the expenses of reentry, redecoration,
      repair and alterations and the expenses of reletting and second to the
      payment of Rent herein provided to be paid by Tenant. Any excess or
      residue shall operate only as an offsetting credit against the amount of
      Rent due and owing as the same thereafter becomes due and payable
      hereunder, and the use of such offsetting credit to reduce the amount of
      Rent due Landlord, if any, shall not be deemed to give Tenant any fight,
      title or interest in or to such excess or residue and any such excess or
      residue shall belong to Landlord solely, and in no event shall Tenant be
      entitled to a credit on its indebtedness to Landlord in excess of the
      aggregate sum (including Total Base Rent and Rent Adjustments) which would
      have been paid by Tenant for the period for which the credit to Tenant is
      being determined, had no default occurred. No such reentry or
      repossession, repairs, alterations and additions, or reletting shall be
      construed as an eviction or ouster of Tenant or as an election on

                                       23
<PAGE>   27

      Landlord's part to terminate this Lease, unless a written notice of such
      intention is given to Tenant, or shall operate to release Tenant in whole
      or in part from any of Tenant's obligations hereunder, and Landlord, at
      any time and from time to time, may sue and recover judgment for any
      deficiencies remaining after the application of the proceeds of any such
      reletting.

            E. If this Lease is terminated by Landlord pursuant to Section
      20.B(i), Landlord shall be entitled to recover from Tenant all Rent
      accrued and unpaid for the period up to and including such termination
      date, as well as all other additional sums payable by Tenant, or for which
      Tenant is liable or for which Tenant has agreed to indemnify Landlord
      under any of the provisions of this Lease, which may be then owing and
      unpaid, and all costs and expenses, including court costs and attorneys'
      fees incurred by Landlord in the enforcement of its rights and remedies
      hereunder, and, in addition, Landlord shall be entitled to recover as
      damages for loss of the bargain and not as a penalty (i) the unamortized
      portion of Landlord's contribution to the cost of tenant improvements and
      alterations, if any, installed by either Landlord or Tenant pursuant to
      this Lease, (ii) the aggregate sum which at the time of such termination
      represents the excess, if any, of the present value of the aggregate rents
      which would have been payable after the termination date had this Lease
      not been terminated, including, without limitation, Base Rent at the
      annual rate or respective annual rates for the remainder of the Term
      provided for in this Lease and the amount reasonably projected by Landlord
      to represent Rent Adjustments for the remainder of the Term pursuant to
      this Lease, over the then present value of the then aggregate fair rental
      value of the Premises for that portion of the Term, beginning on the date
      occurring six (6) months after the date on which this Lease is terminated
      by Landlord through the end of the Term, such present worth to be computed
      in each case on the basis of a ten percent (10%) per annum discount from
      the respective dates upon which such rentals would have been payable
      hereunder had this Lease not been terminated, and (iii) any damages in
      addition thereto, including reasonable attorneys' fees and court costs,
      which Landlord sustains as a result of the breach of any of the covenants
      of this Lease other than for the payment of Rent.

            F. Subject to the provisions of Section 21, all property of Tenant
      removed from the Premises by Landlord pursuant to any provision of this
      Lease or applicable law may be handled, removed or stored by Landlord at
      the cost and expense of Tenant, and Landlord shall not be responsible in
      any event for the value, preservation or safekeeping thereof. Tenant shall
      pay Landlord for all expenses incurred by Landlord with respect to such
      removal and storage so long as the same is in Landlord's possession or
      under Landlord's control. All such property not removed from the Premises
      or retaken from storage by Tenant within thirty (30) days after the end of
      the Term, however terminated, at Landlord's option, shall be conclusively
      deemed to have been conveyed by Tenant to Landlord as by bill of sale
      without further payment or credit by Landlord to Tenant.

            G. The nonprevailing party shall pay all of the prevailing party's
      costs, charges and expenses, including court costs and attorneys' fees,
      incurred by the prevailing party in enforcing the nonprevailing party's
      obligations under this Lease. In addition, Tenant shall pay all of
      Landlord's costs, charges and expenses (including costs and attorneys'

                                       24

<PAGE>   28

      fees incurred by Landlord) in any litigation, negotiation or transaction
      in which Tenant causes Landlord, without Landlord's fault, to become
      involved or concerned.

            H. If Tenant is adjudged bankrupt, or a trustee in bankruptcy is
      appointed for Tenant, Landlord and Tenant, to the extent permitted by law,
      agree to request that the trustee in bankruptcy determine within sixty
      (60) days thereafter whether to assume or to reject this Lease.

            I. If the term of any lease, other than this Lease and excluding the
      Tenant's right to use the Construction Office Space pursuant to Section 33
      of this Lease, made by Tenant for any premises in the Building shall be
      terminated or terminable after the making of this Lease because of any
      default by Tenant under such other lease, such fact shall empower
      Landlord, at Landlord's sole option, to terminate this Lease by notice to
      Tenant.

            J. Notwithstanding anything to the contrary contained in this Lease,
      Landlord and Tenant shall each use commercially reasonable efforts to
      mitigate any damages resulting from a default of the other party under
      this Lease.

            Landlord's obligation to mitigate damages after a default by Tenant
      under this Lease shall be satisfied in full if Landlord undertakes to
      lease the Premises to another tenant (a "Substitute Tenant") in accordance
      with the following criteria:

               (i)   Landlord shall have no obligations to solicit or
                     entertain negotiations with any other prospective
                     tenants for the Premises until Landlord obtains full and
                     complete possession of the Premises including, without
                     limitation, the final and unappealable legal right to
                     relet the Premises free of any claim of Tenant;

               (ii)  Landlord shall not be obligated to offer the Premises to
                     a prospective tenant when other premises in the Building
                     suitable for that prospective tenant's use are
                     available;

               (iii) Landlord shall not be obligated to lease the Premises to
                     a Substitute Tenant for a rental less than the current
                     fair market rental then prevailing for similar uses in
                     comparable building in the same market area as the
                     Building, nor shall Landlord be obligated to enter into
                     a new lease under other terms and conditions that are
                     unacceptable to Landlord under Landlord's then current
                     leasing policies for comparable space in the Building;

               (iv)  Landlord shall not be obligated to enter into a lease
                     with any tenant whose use would:

                                       25
<PAGE>   29

                        (A)   violate any restriction, covenant, or requirement
                              contained in the lease of another tenant of the
                              Building;

                        (B)   adversely affect the reputation of the Building;
                              or

                        (C)   be incompatible with the operation of the Building
                              as a first class office building;

                  (v)   Landlord shall not be obligated to enter into a lease
                        with any proposed Substitute Tenant which does not have,
                        in landlord's reasonable opinion, sufficient financial
                        resources or operating experience to operate the
                        Premises in a first class manner; and

                  (vi)  Landlord shall not be required to expend any amount of
                        money to alter, remodel, or otherwise make the Premises
                        suitable for use by a proposed Substitute Tenant unless:

                        (A)   Tenant pays any such sum to Landlord in advance of
                              Landlord's execution of a lease which such tenant
                              (which payment shall not be in lieu of any damages
                              or other sums to which Landlord may be entitled as
                              a result of Tenant's default under this Lease); or

                        (B)   Landlord, in Landlord's sole discretion,
                              determines that any such expenditure is
                              financially justified in connection with entering
                              into any such substitute lease.

            Upon compliance with the above criteria regarding the releasing of
      the Premises after a default by Tenant, Landlord shall be deemed to have
      fully satisfied Landlord's obligation to mitigate damages under this Lease
      and under any law or judicial ruling in effect on the date of this Lease
      or at the time of Tenant's default. Tenant waives and releases, to the
      fullest extent legally permissible, any right to assert in any action by
      Landlord to enforce the terms of this Lease, any defense, counterclaim, or
      rights of setoff or recoupment respecting the mitigation of damages by
      Landlord, unless and to the extent Landlord maliciously or in bad faith
      fails to act in accordance with the requirements of this Section 20.J.

            Tenant's right to seek damages from Landlord as a result of a
      default by Landlord under this Lease shall be conditioned on Tenant taking
      all actions reasonably required, under the circumstances, to minimize any
      loss or damage to Tenant's property or business, or to any of Tenant's
      officers, employees, agents, invitees, or other third parties that may be
      caused by any such default of Landlord.

      21.   SURRENDER OF POSSESSION. Upon the expiration or other termination of
the Term, Tenant shall quit and surrender to Landlord the Premises, broom clean,
in good order and

                                       26
<PAGE>   30

condition, ordinary wear and tear excepted, surrender all keys to the Premises
to Landlord, and Tenant shall remove all of its property except as otherwise
specifically provided herein.

      If Tenant does not remove its property of every kind and description from
the Premises prior to the end of the Term, however ended, at Landlord's option
and upon ten (10) days prior notice to Tenant, Tenant shall be conclusively
presumed to have conveyed the same to Landlord under this Lease as a bill of
sale without further payment or credit by Landlord to Tenant and Landlord may
remove the same and Tenant shall pay the cost of such removal to Landlord upon
demand. Tenant's obligation to observe or perform this covenant shall survive
the expiration or other termination of the Term.

      22.   INTENTIONALLY OMITTED.

      23.   COVENANT AGAINST LIENS. Tenant has no authority or power to cause or
permit any lien or encumbrance of any kind whatsoever, whether created by act of
Tenant, operation of law or otherwise, to attach to or be placed upon Landlord's
title or interest in the Building, the Project or Premises, and any liens and
encumbrances created by Tenant shall attach to Tenant's interest only. Tenant
covenants and agrees not to suffer or permit any lien of mechanics or
materialmen or others to be placed against the Land, Building or the Premises
with respect to work or services claimed to have been performed for or materials
claimed to have been furnished to Tenant or the Premises, and in case of any
such lien attaching, Tenant covenants and agrees to cause it to be released and
removed of record no later than thirty (30) days following notice of said lien.

      24.   TENANT'S PAYMENTS UPON EXECUTION.

            A. As additional security for the faithful and prompt performance of
      its obligation herein, Tenant has concurrently with the execution of this
      Lease delivered to Agent an irrevocable unconditional standby letter of
      credit (the "Letter of Credit") in the stated amount of One Hundred
      Thousand Dollars ($100,000.00). The Letter of Credit shall be issued by a
      financial institution and be in both form and substance acceptable to
      Landlord and shall have an expiry date of December 31, 1998. If a default
      shall occur, Landlord shall have the right (but not the obligation) to
      redeem all or any portion of the Letter of Credit to cure such default by
      notifying in writing both Tenant and the credit institution issuing the
      Letter of Credit of such default following expiration of the period to
      cure such default, if any. The amount of the Letter of Credit shall be
      reduced on a dollar-for-dollar basis by the amount of each Monthly Base
      Rental payment received by Landlord (as evidenced by delivery to Landlord
      of a substitute Letter of Credit as described in the immediately
      succeeding paragraph (except as to the applicable reduced stated amount))
      until the amount of the Letter of Credit is reduced to zero. Within thirty
      (30) days after the amount of the Letter of Credit has been reduced to
      zero, Landlord shall return such Letter of Credit to Tenant. If landlord
      shall sell or transfer its interest in the Building, Landlord shall have
      the right to obligate Tenant to amend said Letter of Credit so that it is
      payable to such purchaser or transferee, in which event Tenant shall look
      solely to such purchaser or transferee for the return of the Letter of
      Credit, and

                                       27
<PAGE>   31

      Landlord thereupon shall be released from all liability to Tenant for the
      return of the Letter of Credit.

      Provided Landlord receives at least thirty (30) days prior written notice
      thereof, Tenant shall have the right to deliver to Landlord a letter of
      credit in substitution for and in replacement of the Letter of Credit in
      accordance with the immediately preceding paragraph, issued by a financial
      institution and in a form and content reasonably acceptable to Landlord,
      and upon receipt of such substituted letter of credit, Landlord shall
      deliver the Letter of Credit to Tenant.

      In the event the Letter of Credit issuer or the issuer of any substitute
      letter of credit elects not to renew the Letter of Credit in accordance
      with its terms, if required hereunder, Landlord shall have the fight to
      draw the entire amount of the Letter of Credit no earlier than thirty (30)
      days prior to the expiration or termination of the Letter of Credit. Upon
      receipt of cash in the amount of such draw (the "Cash Deposit"), Landlord
      shall hold, apply, reduce and otherwise exercise its rights in connection
      with the Cash Deposit as security for performance by Tenant under this
      Lease in the same manner as Landlord shall hold, apply, reduce and
      otherwise exercise its rights in connection with the Letter of Credit
      pursuant to the terms of this Section 24(A). Landlord shall hold the Cash
      Deposit in the same manner as Landlord holds other cash security deposits
      of tenants of the Building. Once drawn, the Letter of Credit will not be
      reinstated to its original amount. Said deposit shall not be deemed an
      advance payment of Rent or measure of Landlord's damages for any default
      hereunder by Tenant.

            B. Notwithstanding anything to the contrary herein set forth, the
      Monthly Base Rental payable for the first month of the Term shall be due
      and paid to Landlord concurrently with the execution hereof by Tenant.

      25.   RULES AND REGULATIONS. Tenant shall occupy and use the Premises
during the Term for the purpose above specified and none other and shall comply
with the following provisions:

            A. Tenant will not make or permit to be made any use of the Premises
      which, directly or indirectly is forbidden by public law, ordinance, or
      governmental regulation or which may be dangerous to persons or property,
      or which may invalidate or increase the premium cost of any policy of
      insurance carried on the Building or covering its operations; Tenant shall
      not do, or permit to be done, any act or thing upon the Premises which
      will be in conflict with fire insurance policies covering the Building.
      Tenant, at its sole cost and expense shall comply with all rules,
      regulations or requirements of the local inspection and rating bureau, or
      any other similar body, and shall not do or permit anything to be done
      upon said Premises or bring or keep anything thereon in violation of
      rules, regulations, or requirements of the Fire Department, local
      inspection and rating bureau, fire insurance rating organization or other
      authority having jurisdiction and then only in such quantity and manner of
      storage as not to increase the rate of fire insurance applicable to the
      Building;

                                       28
<PAGE>   32

            B. Any sign installed in the Premises or anywhere within the
      Building shall be installed by Landlord at Tenant's cost and in such
      manner, character and style as Landlord may approve in writing, which
      approval shall not be unreasonably withheld;

            C. Tenant shall not advertise the business, profession or activities
      of Tenant conducted in the Building in any manner which violates the
      letter or spirit of any code of ethics adopted by any recognized
      association or organization pertaining to such business, profession or
      activities, and shall not use the name of the Building for any purpose
      other than that of business address of Tenant, and shall never use any
      picture or likeness of the Building in any circulars, notices;
      advertisements or correspondence without Landlord's express prior consent
      in writing, which consent shall not be unreasonably withheld;

            D. Tenant shall not obstruct, use for storage or use for any purpose
      other than ingress and egress, the sidewalks, entrances, passages, courts,
      corridors, vestibules, halls, elevators and stairways of the Building;

            E. No bicycle or other vehicle and no dog, other than a seeing eye
      dog, or other animal shall be brought or permitted to be in the Building
      or any part thereof;

            F. Tenant shall not make or permit any noise or odor that is
      objectionable to other occupants of the Building to emanate from the
      Premises, and shall not create or maintain a nuisance thereon, and shall
      not disturb, solicit or canvass any occupant of the Building, and shall
      not do any act tending to injure the reputation of the Building;

            G. Tenant shall not install any musical instrument or equipment in
      the Building or any antennas, aerial wires or other equipment inside or
      outside the Building, without, in each and every instance, prior approval
      in writing by Landlord, which approval shall not be unreasonably withheld.
      The use thereof, if permitted, shall be subject to control by Landlord to
      the end that others shall not be disturbed or annoyed;

            H. Tenant shall not waste water by tying, wedging or otherwise
      fastening open any faucet;

            I. No additional locks or similar devices shall be attached to any
      door or window. No keys for any door or window other than those provided
      by Landlord shall be made. If more than two keys for one lock are desired
      by Tenant, Landlord may provide the same upon payment by Tenant. Upon
      termination of this Lease or of Tenant's possession, Tenant shall
      surrender all keys of the Premises and shall make known to Landlord the
      explanation of all combination locks on safes, cabinets, and vaults;

            J. Tenant shall be responsible for protecting the Premises and all
      of its property located therein and for the safety of all persons therein;

                                       29
<PAGE>   33

            K. If Tenant desires telegraphic, telephonic, communications,
      burglar alarm or signal service, Landlord will, upon request, direct where
      and how connections and all wiring for such service shall be introduced
      and run. Without such directions, no boring, cutting or installation of
      wires or cables is permitted;

            L. Shades, draperies or other forms of inside window covering must
      be of such shape, color and material as are approved by Landlord;

            M. Tenant shall pay, as a late charge in the event any installment
      of Total Base Rental, Rent Adjustments, Rent Adjustment Deposits and any
      other charge owed by Tenant hereunder is not paid within five (5) days
      following Landlord's late payment notice to Tenant; provided, however,
      following the Landlord's second late payment notice to Tenant in any
      calendar year, any future late payment by Tenant in the calendar year
      shall incur the late charge from the date said payment was due, the
      greater of One Hundred Dollars ($100.00) or an amount equal to five
      percent (5%) of the amount due for each and every thirty (30) day period
      that said amount remains unpaid (but in no event shall the amount of such
      late charge exceed an amount based upon the highest legally permissible
      rate chargeable at any time by Landlord under the circumstances). Should
      Tenant make a partial payment of past due amounts, the amount of such
      partial payment shall be applied first to reduce all accrued and unpaid
      late charges, in inverse order of their maturity, and then to reduce all
      other past due amounts, in inverse order of their maturity;

            N. Tenant shall not overload any floor. Safes, furniture and all
      large articles shall be brought through the Building and into the Premises
      at such times and in such manner as Landlord shall direct and at Tenant's
      sole risk and responsibility. Tenant shall list all furniture, equipment
      and similar articles to be removed from the Building, and the list must be
      approved, which approval will not be unreasonably withheld, at the Office
      of the Building or by a designated person before building employees will
      permit any article to be removed;

            O. Unless Landlord gives advance written consent in each and every
      instance, Tenant shall not install or operate any steam or internal
      combustion engine, boiler, machinery, refrigerating or heating device or
      air-conditioning apparatus in or about the Premises, or carry on any
      mechanical business therein, or use the Premises for housing
      accommodations or lodging or sleeping purposes, or do any cooking therein
      or install or permit the installation of any vending machines, or use any
      illumination other than electric light, or use or permit to be brought
      into the Building any inflammable oils or fluids such as gasoline,
      kerosene, naptha and benzene, or any explosive or other articles hazardous
      to persons or property. The Landlord hereby acknowledges that the Tenant
      shall be allowed to install a full-size refrigerator, an ice maker, a
      microwave, computers and air conditioning equipment for the computers in
      the Premises subject to the Landlord's approval of the Tenant's Plans for
      the Premises;

                                       30
<PAGE>   34

            P. Tenant shall not place or allow anything to be against or near
      the glass of partitions, doors or windows of the Premises which may
      diminish the light in, or be unsightly from the exterior of the Building,
      public halls or corridors;

            Q. Tenant shall not install in the Premises any equipment which uses
      a substantial amount of electricity without the advance written consent of
      Landlord, which consent will not be unreasonably withheld. Tenant shall
      ascertain from Landlord the maximum amount of electric current which can
      safely be used in the Premises, taking into account the capability of the
      electric wiring in the Building and the Premises and the needs of other
      tenants in the Building and shall not use more than such safe capacity.
      Landlord's consent to the installation of electric equipment shall not
      relieve Tenant from the obligation not to use more electricity than such
      safe capacity;

            R. Tenant may not install carpet padding or carpet by means of a
      mastic, glue or cement without Landlord's prior written consent. Such
      installation shall be by tackless strip or double-faced tape only;

            S. Tenant shall not, without Landlord's prior written consent in
      each instance, do any cooking, baking, heating, preparation, serving or
      selling of any food or beverages in the Premises, or permit the same to
      occur, except for coffee service and microwave ovens to service Tenant.

            T. If Tenant breaches any covenant or condition of this Section 25,
      then in addition to all other liabilities, rights and remedies for breach
      of any covenant of this Section 25, Tenant shall pay to Landlord all
      damages caused by such breach and shall also pay to Landlord as Additional
      Rent an amount equal to any increase in insurance premium or premiums
      caused by such breach. Landlord shall have the right to make and Tenant
      shall observe, such reasonable rules and regulations as Landlord or its
      agent may from time to time adopt on such reasonable notice to be given as
      Landlord may elect. Nothing in this Lease shall be construed to impose
      upon Landlord any duty or obligation to enforce provisions of this Section
      25 or any rules and regulations hereafter adopted, or the terms, covenants
      or conditions of any other lease as against any other tenant, and Landlord
      shall not be liable to Tenant for violation of the same by any other
      tenant, its servants, employees, agents, visitors or licensees. Landlord
      shall enforce all rules and regulations in a uniform manner.

      26.   MISCELLANEOUS.

            A. No payment by Tenant or receipt by Landlord of a lesser amount
      than any installment or payment of Rent due shall be deemed to be other
      than a payment on account of the amount due and no endorsement or
      statement on any check or any letter accompanying any check or payment of
      Rent shall be deemed an 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 payment of Rent or pursue any other
      remedies available to Landlord. No receipt of money by landlord from
      Tenant after the termination of this Lease or after the service of any
      notice or after the commencement

                                       31
<PAGE>   35

      of any suit, or after final judgment for possession of the Premises shall
      reinstate, continue or extend the term of this Lease or affect any such
      notice, demand or suit.

            B. No waiver of any default of Tenant hereunder shall be implied
      from any omission by Landlord to take any action on account of such
      default and if such default be repeated, no express waiver shall affect
      any default other than the default specified in the express waiver and
      that only for the time and to the extent therein stated. Receipt of Rent
      by Landlord, with knowledge of any breach of this Lease by Tenant or of
      any default by Tenant in the observance or performance of any of the
      conditions or covenants of this Lease, shall not be deemed to be a waiver
      of any provision of this Lease.

            C. The words "Landlord" and "Tenant" wherever used in the Lease
      shall be construed to mean plural where necessary, and the necessary
      grammatical changes required to make the provisions hereof apply either to
      corporations, or individuals, men or women, shall in all cases be assumed
      as though in each case fully expressed. The term "Tenant" shall include
      Tenant's agents, employees, contractors, officers, invitees, successors
      and others using the Premises with the expressed or implied permission of
      Tenant.

            D. Each provision hereof shall extend to and shall, as the case may
      require, bind and inure to the benefit of Landlord and Tenant and their
      respective heirs, legal representative, successors and assigns in the
      event this Lease has been assigned with the express written consent of
      Landlord; provided, however, this provision shall not be construed to
      permit any assignment or subletting by Tenant.

            E. The execution of this Lease by Tenant and delivery of same to
      Landlord or Agent does not constitute a reservation of or option for the
      Premises or an agreement to enter into a Lease. This Lease shall become
      effective only if and when Landlord executes and delivers same to Tenant;
      provided, however, the execution and delivery by Tenant of this Lease to
      Landlord or Agent shall constitute an irrevocable offer by Tenant to lease
      the Premises on the terms and conditions herein contained, which offer may
      not be withdrawn or revoked for fifteen (15) days after such execution and
      delivery. If Tenant is a corporation, partnership, association or any
      other entity, it shall deliver to Landlord, concurrently with the delivery
      to Landlord of an executed Lease, certified resolutions of Tenant's
      directors or other governing person or body authorizing execution and
      delivery of this Lease and the performance by Tenant of its obligations
      hereunder and the authority of the party executing the Lease as having
      been duly authorized to so do.

            F. All amounts (unless otherwise provided herein, and other than the
      Total Base Rent and Rent Adjustments, which shall be due as hereinbefore
      provided) owed by Tenant to Landlord hereunder shall be deemed Additional
      Rent and be paid within thirty (30) days from the date Landlord renders
      statements of account therefor. All such amounts (including Total Base
      Rent and Rent Adjustments) shall bear interest from the date due until the
      date paid at the rate of two percent (2%) above the prime or base rate of
      interest published by The First National Bank of Chicago, Chicago,
      Illinois on the date

                                       32
<PAGE>   36

      that any payment is due or at the maximum legal rate of interest, allowed
      by law, if such maximum legal rate is applicable and lower. Whenever Rent
      is referred to in this Lease, it shall include (but not by way of
      exclusion) Total Base Rent, Rent Adjustments and Additional Rent.

            G. All riders and exhibits attached to this Lease referred to herein
      are hereby made a part of this Lease as though inserted in this Lease.

            H. The headings of sections are for convenience only and do not
      limit or construe the contents of the sections.

            I. If Tenant shall occupy the Premises prior to the beginning of the
      Term of this Lease with Landlord's consent, all of the provisions of this
      Lease shall be in full force and effect as soon as Tenant occupies the
      Premises.

            J. Should any mortgage, leasehold or otherwise, require a
      modification or modifications of this Lease, which modification or
      modifications will not bring about any increased cost or expense to Tenant
      or in any other way substantially change the rights and obligations of
      Tenant hereunder or reconfigure or relocate the Premises, then and in such
      event, Tenant agrees that this Lease may be so modified.

            K. Landlord and Tenant represent that they have dealt directly with
      and only with Agent and Cooperating Broker listed in Section 1 hereof, if
      any, as broker in connection with this Lease and that insofar as either
      Tenant or Landlord know, no other broker negotiated this Lease or is
      entitled to any commission in connection herewith. Both parties indemnify
      and hold the other party, its trustees, partners and agents, and their
      respective agents and employees harmless from all claims of any other
      broker or brokers in connection with this Lease.

            L. Both parties shall at any time and from time to time upon not
      less than fifteen (15) days prior written request from the other party
      execute, acknowledge and deliver to the requesting party, in form
      reasonably satisfactory to the requesting party and/or the requesting
      party's mortgagee, a written statement certifying (if true) that Tenant
      has accepted the Premises, that this Lease is unmodified and in full force
      and effect (or if there have been modifications, that the same is in full
      force and effect as modified and stating the modifications), that the
      requesting party is not in default hereunder, the date to which the Rent
      and other charges have been paid in advance, if any, and such other
      accurate certification as may reasonably be requested by the requesting
      party or the requesting party's mortgagee, and agreeing to give copies of
      all notices to any mortgagee of the requesting party. It is intended that
      any such statement delivered pursuant to this subsection may be relied
      upon by any prospective purchaser or mortgagee of the Premises and their
      respective successors and assigns.

            M. Landlord's title is and always shall be paramount to the title of
      Tenant, and nothing herein contained shall empower Tenant to do any act
      which can, shall or may encumber such title.

                                       33
<PAGE>   37

            N. The laws of the State of Connecticut shall govern the validity,
      performance and enforcement of this Lease and any proceedings brought to
      enforce this Lease or otherwise in connection with this Lease shall be
      brought within the State of Connecticut.

            O. If any term, covenant or condition of this Lease or application
      thereof to any person or circumstance shall, to any extent, be invalid or
      unenforceable, the remainder of this Lease, or the application of such
      term, covenant or condition to persons or circumstances other than those
      as to which it is held invalid or unenforceable, shall not be affected
      thereby and each term; covenant or condition of this Lease shall be valid
      and be enforced to the fullest extent permitted by law.

            P. Tenant warrants and represents that it has full power and
      authority to execute this Lease. In the event Tenant is a general
      partnership or consists of two or more individuals, all present and future
      partners or individuals, as applicable, shall be jointly and severally
      liable hereunder. Landlord warrants and represents that it has full power
      and authority to execute this Lease.

            Q. Landlord has no obligation pursuant to this Lease except as
      expressly provided for herein. Landlord's liability hereunder shall cease
      upon the transfer of Landlord's interest in this Lease. Nothing in this
      Lease shall restrict the right of Landlord to sell, convey or otherwise
      transfer the Building or assign this Lease subject only to the rights of
      Tenant under this Lease. Any such sale, conveyance or assignment shall
      operate to release Landlord from liability from and after the effective
      date thereof with respect to all of the covenants, terms and conditions of
      this Lease, express or implied, and Tenant shall thereafter look solely to
      Landlord's successor in interest in and to this Lease with respect to
      liability accruing thereafter under this Lease. This Lease shall not be
      affected by any such sale, conveyance or assignment and Tenant shall
      attorn to Landlord's successor in interest thereunder. Tenant shall have
      no obligation pursuant to this Lease except as expressly provided for
      herein.

            R. This Lease sets forth all the covenants, promises, agreements,
      conditions and understandings between Landlord and Tenant, concerning the
      Premises, and there are no covenants, promises, agreements, conditions or
      understandings, either oral or written, between them other than herein set
      forth, except as herein otherwise provided; no subsequent alteration,
      amendment, change or addition to this Lease shall be binding upon Landlord
      or Tenant unless reduced to writing and signed by them.

            S. Notices hereunder shall be in writing and shall be deemed given
      when received if:

               (i)   served by Landlord upon Tenant by leaving a notice at
                     the Premises or forwarding through certified or
                     registered mail, postage prepaid, or by recognized
                     overnight carrier, to Tenant at the Premises with a copy
                     to Rafael Santiago, Esq. at Robinson & Cole, LLP, One
                     Commercial Plaza, Hartford, Connecticut 06103-3597; and

                                       34
<PAGE>   38

                  (ii)  served by Tenant upon Landlord when addressed to
                        Landlord and served by forwarding through certified or
                        registered mail, postage prepaid, or by recognized
                        overnight carrier, to Agent at the address set forth in
                        Section 1 with a copy to: Rudnick & Wolfe, 203 North
                        LaSalle Street, Chicago, Illinois 60601, Attn: James T.
                        Mayer, Esq. or to such other address and such other
                        parties as notified by Landlord.

            T.    This Lease does not grant any rights to light or air over or
      about the real property of Landlord. Landlord specifically excepts and
      reserves to itself the use of any roofs, the exterior portions of the
      Project, all rights to the land and improvements below the improved floor
      level of the Project, to the improvements and air rights above the Project
      and to the improvements and air rights located outside the demising walls
      of the Project and to such areas within the Project required for
      installation of utility lines and other installations required to serve
      any occupants of the Project and to maintain and repair same, and no
      rights with respect thereto are conferred upon Tenant, unless otherwise
      specifically provided herein.

            U.    The preparation of this Lease has been a joint effort of the
      parties hereto and the resulting documents shall not, solely as a matter
      of judicial construction, be construed more severely against one of the
      parties than the other.

            V.    Tenant agrees to comply, at Tenant's sole cost and expense,
      with all statutes, laws, ordinances, orders, codes, rules, regulations and
      other acts having the force or effect of law, of all state, federal,
      municipal and other agencies, authorities or bodies having jurisdiction
      over the Premises or the Building, now or hereafter in force, relating to
      the Premises, including, but not limited to, the use, condition, occupancy
      or any alteration of the Premises.

            W.    Provided Tenant shall not be in default of the terms and
      provisions of this Lease, during the Term, Landlord shall provide to
      Tenant on a first-come, first-serve basis, in common with other tenants of
      the Building and any other parties permitted by Landlord, fifty-six (56)
      unreserved surface parking spaces and four (4) reserved parking spaces
      designated as space numbers 80, 81, 82 and 83 without charge.

      27.   QUIET ENJOYMENT. Subject to the provisions of this Lease, Landlord
covenants that Tenant, on paying the Rent and performing the covenants of this
Lease on its part to be performed, shall and may peaceably have, hold and enjoy
the Premises for the Term.

      29.   ADA. The parties acknowledge that the Americans With Disabilities
Act of 1990 (42 U.S.C. {12101 ET SEQ.) and regulations and guidelines
promulgated thereunder, as all of the

                                       37
<PAGE>   41

same may be amended and supplemented from time to time (collectively referred to
herein as the "ADA") establish requirements under Title III of the ADA ("Title
III") pertaining to business operations, accessibility and barrier removal, and
that such requirements may be unclear and may or may not apply to the Premises
and Building depending on, among other things: (1) whether Tenant's business
operations are deemed a "place of public accommodation" or a "commercial
facility", (2) whether compliance with such requirements is "readily achievable"
or "technically infeasible", and (3) whether a given alteration, affects a
"primary function area" or triggers so-called "path of travel" requirements. The
parties acknowledge and agree that Tenant has been provided an opportunity to
inspect the Premises and Building sufficient to determine whether or not the
Premises and Building in their current condition as of the date hereof deviate
in any manner from the ADA Accessibility Guidelines ("ADAAG") or any other
requirements under the ADA or state or local law pertaining to the accessibility
of the Premises or the Project. Tenant further acknowledges and agrees that
except as may otherwise be specifically provided below, Tenant accepts the
Premises and Building in "as-is" condition and agrees that Landlord makes no
representation or warranty as to whether the Premises or Building conform to the
requirements of the ADAAG or any other requirements under the ADA or state or
local law pertaining to the accessibility of the Premises or the Project. Tenant
has prepared or reviewed the plans and specifications for the Tenant's Work and
has independently determined that such plans and specifications are in
conformance with the ADAAG, any other requirements of the ADA, state and local
law. Tenant further acknowledges and agrees that to the extent that Landlord
prepared, reviewed or approved any of those plans and specifications, such
action shall in no event be deemed any representation or warranty that the same
comply with any requirements of the ADA or other applicable law. Notwithstanding
anything to the contrary in this Lease, the parties hereby agree to allocate
responsibility for Title III compliance as follows: (a) Landlord shall be
responsible for performing ADA Title III compliance work required in the common
areas of the Building on the floors on which the Premises are located; (b)
Tenant shall be responsible for all Title III compliance and costs in connection
with the Premises, including structural work, if any, and including any
leasehold improvements or other work to be performed in the Premises under or in
connection with this Lease; and (c) Landlord shall perform, and Tenant shall be
responsible for the cost of, any so-called Title III "path of travel"
requirements triggered by any construction activities or alterations in the
Premises. Except as set forth above with respect to Landlord's Title III
obligations, Tenant shall be solely responsible for all other requirements under
the ADA or other applicable law relating to the Tenant or any affiliates or
persons or entities related to the Tenant (collectively, "Affiliates"),
operations of the Tenant or Affiliates, or the Premises, including, without
limitation, requirements under Title I of the ADA pertaining to Tenant's
employees.

      30.   WAIVER OF RIGHTS. Tenant hereby waives for itself and all those
claiming under it, any rights which it may have under any present or future
constitution, statute or rule of law: (i) to redeem the Premises after
termination of Tenant's right of occupancy by order or judgment of any court or
by any legal process or writ; (ii) which exempts property from liability for

prior to Landlord obtaining any prejudgment remedy; in connection herewith,

hereto against the other or any matters whatsoever arising out of or in any way
connected with this Lease.

      31.   TERMINATION OF EXISTING LEASE. Landlord and Tenant agree that, upon
the execution of this Lease by both Landlord and Tenant that certain lease dated
June 16, 1997 (the "Prior Lease") between Glastonbury Land Development Limited
Partnership, the predecessor-in-interest to Landlord, and Tenant (a/k/a BDS
Business Center, Inc.), shall expire as if by lapse of time and shall be of no
further force and effect; provided, however, that any obligations or
liabilities intended to survive the expiration or termination of the Prior Lease
shall remain the respective obligations or liabilities of the respective parties
to the Prior Lease.

      32.   OPTION TO EXTEND. Subject to the terms and provisions of this
Section 32, Tenant shall have one (1) option to extend (an "Option to Extend")
the Term with respect to the entire Leased Premises for a period of sixty (60)
months (the "Extension Period") commencing as of the day after the Termination
Date. Tenant shall exercise each Option to Extend by delivering written notice
("Tenant's Extension Notice") of such exercise to Landlord not less than six (6)
months prior to the Termination Date of the Term. Failure of Tenant to provide
such written notice within the time period set forth above shall be deemed
Tenant's waiver of its rights hereunder and shall result in Tenant losing the
right to extend pursuant to this Section 32. Upon the proper and timely exercise
of the Option to Extend, the term of this Lease with respect to the entire
Leased Premises shall be extended for sixty (60) months and all of the
covenants, conditions and provisions of this Lease shall thereupon be applicable
during the Extension Period except that the Monthly Base Rental to be paid by
Tenant to Landlord during the Extension Period shall be the then-current Market
Rental (hereinafter defined).

      For the purposes of this Lease, the term "Market Rental" shall mean the
rental rate charged by Landlord to renewing/extending tenants for space of
comparable size, location and conditions in comparable property within the
Glastonbury, Connecticut submarket, current as of no earlier than fifteen (15)
months prior to the scheduled expiration of the Term of this Lease. Landlord's
determination of Market Rental shall take into account, without limitation, the
following: locations; quality; age; floor levels; common area factors; finish
allowances; rental abatements; parking charges; lease assumptions; moving
allowances; space planning allowances; refurbishment allowances; and any other
concession or inducement, expense stop, other rental adjustments; credit
standing of tenants; lease term and any other terms that would be relevant, in
Landlord's reasonable judgment, in determining the Market Rental. Within thirty
(30) days after Landlord's receipt of Tenant's Extension Notice, Landlord and
Tenant shall meet to negotiate, in good faith, the Market Rental for the
Extension Period. If Landlord and Tenant, after good faith efforts, are unable
to agree on the Market Rental, and if Landlord's determination of Market Rental
exceeds Tenant's determination of Market Rental by more than twenty-five percent
(25%), then Tenant shall have the option, by delivering notice to Landlord
within three (3) days after the earlier to occur of (a) the expiration of the
aforementioned thirty (30) day period and (b) the termination of Landlord's and
Tenant's negotiations of the Market Rental, to revoke Tenant's Extension Notice
in which event Tenant shall forfeit and have no further extension rights under
this Lease and the Term shall expire as of the Termination Date. If Tenant
elects not to revoke Tenant's Extension Notice as aforesaid, or Landlord's

                                       39
<PAGE>   43

determination of Market Rental does not exceed Tenant's determination of Market
Rental by twenty-five percent (25%), the Market Rental shall be determined as
follows:

            A. Within fifteen (15) days after the expiration of the
      aforementioned thirty (30) day period, Landlord and Tenant each shall
      appoint one real estate broker (individually, a "Broker", and
      collectively, the "Brokers") who shall have been active over the ten (10)
      year period ending on the date of such appointment in the leasing of space
      in commercial properties in the Glastonbury, Connecticut submarket,
      provided that such Brokers shall not have been engaged or employed by the
      party appointing the same within such ten (10) year period (not including
      the engagement or compensation of a Broker by Landlord in such Broker's
      capacity as an outside tenant broker). Thereafter, Landlord and Tenant
      each shall deliver notice of their respective determinations to each other
      and the Brokers within five (5) days after the expiration of the
      aforementioned fifteen (15) day period, and such determinations shall be
      submitted for final determination in accordance with this Section 32. The
      determination of the Brokers shall be limited solely to the issue of
      whether Landlord's or Tenant's submitted determination of Market Rental
      for the Extension Period is the closest to the actual Market Rental for
      the Extension Period as determined by the Brokers, taking into account the
      aforementioned items used in determining Market Rental.

            B. The Brokers shall, within ten (10) days after the date of the
      appointment of the last appointed Broker, agree upon and appoint a third
      Broker who shall be qualified under the same criteria set forth above for
      qualification of the initial two (2) Brokers.

            C. The three (3) Brokers shall, within thirty (30) days of the
      appointment of the third Broker, reach a decision as to whether the
      parties shall use Landlord's or Tenant's submitted determination of Market
      Rental and shall notify Landlord and Tenant thereof.

            D. The decision of the majority of the three (3) Brokers shall be
      binding upon Landlord and Tenant.

            E. If either Landlord or Tenant fails to appoint a Broker within the
      aforementioned fifteen (15) day period, then the Broker appointed by the
      other party shall reach a decision, notify Landlord and Tenant thereof,
      and such Broker's decision shall be binding upon Landlord and Tenant.

            F. If the two (2) appointed Brokers fail to agree upon and appoint a
      third Broker, or both Landlord and Tenant fail to appoint a Broker, then
      the appointment of the third Broker or any Broker shall be dismissed and
      the matter to be decided shall be forthwith submitted to arbitration under
      the provisions of the American Arbitration Association, but subject to the
      instructions set forth in this Section 32.

            G. Landlord and Tenant shall each pay the cost of the Broker
      appointed by it and one-half (1/2) of the cost of the third Broker.

                                       40
<PAGE>   44

      If the Extension Period shall commence prior to the final determination of
the Market Rental, Tenant shall commence paying Monthly Base Rental and
adjustments thereto, if any, utilizing the Market Rental specified by Landlord
in its notice of the Market Rental for such space or period. Following
determination of the Market Rental in accordance with this Section 32, Landlord
and Tenant, by a cash payment within thirty (30) days after the date of such
determination, shall adjust between themselves the difference, if any, between
the Base Rental and adjustments thereto (including interest on such difference
at an interest rate equal to one percent (1%) per annum above the then-current
published prime or corporate base rate charged by First National Bank of
Chicago, or its successor), if any, paid by Tenant pursuant to the foregoing
sentence and the Monthly Base Rental and adjustments thereto, if any, actually
owed by Tenant pursuant to the terms of this Lease for the period prior to such
determination.

      Notwithstanding the foregoing, Tenant's right to exercise the Option to
Extend is, at Landlord's option, made expressly subject to the conditions that
(i) on the date Tenant delivers to Landlord Tenant's Extension Notice and (ii)
on the date upon which this Lease shall expire, neither this Lease nor Tenant's
right to possession of the Premises has been previously terminated and Tenant is
not in default under this Lease.

      33.   CONSTRUCTION OFFICE SPACE. During the period the Premises is being
constructed, Tenant shall have the right to continue to occupy the approximately
three thousand square feet (3,000 sq. ft.) of office space located on the third
floor of the Building (hereinafter referred to as "Construction Office Space").
Tenant acknowledges that it is currently using and occupying the Construction
Office Space, that it is taking the Construction Office Space in an "As Is",
"Where Is" condition, and that Landlord has made no promises to alter, remodel,
decorate, clean or improve the Construction Office Space and no representation
respecting the condition of the Construction Office Space has been made by
Landlord to the Tenant. Tenant shall not be required to pay any Rent for the
Construction Office Space. Tenant's right to use and occupy the Construction
Office Space shall terminate upon the Commencement Date of this Lease. Within
ten (10) days following the Commencement Date of this Lease, Tenant shall quit
and surrender to Landlord the Construction Office Space, broom clean, in good
order and condition, ordinary wear and tear excepted, surrender all keys to the
Construction Office Space to Landlord, and Tenant shall remove all of its
property. If Tenant does not remove its property of every kind and description
from the Construction Office Space prior to the Commencement Date of this Lease,
at Landlord's option and upon ten (10) days prior notice to Tenant, Tenant shall
be conclusively presumed to have conveyed the same to Landlord under without
further payment or credit by Landlord to Tenant and Landlord may remove the same
and Tenant shall pay the cost of such removal to Landlord upon demand. Tenant's
obligation to observe or perform this covenant shall survive the expiration or
other termination of the Lease.

      34.   SATELLITE DISH. Tenant, at its sole cost and expense, shall have the
right to install a receiving and/or transmitting satellite dish on the roof of
the Building. The location of the satellite dish shall be determined by Landlord
in its reasonable discretion. Tenant shall be responsible for obtaining all the
necessary permits required for the installation and operation of the satellite
dish. In the event Tenant elects to install said satellite dish, Tenant shall be
required to use the roofing contractor selected by Landlord to patch and/or
repair any damage to the roof caused by the installation of the satellite dish.
Tenant agrees that Tenant shall be solely

                                       41
<PAGE>   45

responsible for the repair, replacement, removal and maintenance of the
satellite dish and does hereby agree that the satellite dish shall not be
ins/ailed until Landlord has approved the size, location and manner of
installation of the satellite dish on the Building. Tenant shall remove the
satellite dish upon the expiration or earlier termination of this Lease and
shall repair any and all damage to the Building resulting from said removal.
Tenant agrees to indemnify and save the indemnitees (as defined herein) harmless
against any and all claims, demands, costs and expenses, including reasonable
attorney's fees for the defense thereof, arising from Tenant's installation,
use, repair, maintenance, replacement or removal of the satellite dish or from
any breach or default on the part of Tenant in the performance of any covenant
or agreement on the part of Tenant to be performed pursuant to the terms of this
Section 34, or from any act or negligence of Tenant, its agents, servants,
employees or invitees, with regard to the installation, use, repair,
maintenance, replacement or removal of the satellite dish. In case of any action
or proceeding brought against any indemnitees by reason of any such claim, upon
notice from Landlord, Tenant covenants to defend such action or proceeding by
counsel reasonably satisfactory to Landlord.

      Re:  Glastonbury Corporate Center
          Glastonbury, Connecticut

      Dear Ms. Paternoster:

      As you know, on July 27, 1998, your Glastonbury office opened its new
      quarters at Glastonbury Corporate Center located at 628 Hebron Avenue. On
      behalf of the owner, TR 628 Hebron Limited Partnership, we would like to
      welcome you to your new offices in the building.

      We are in receipt of the executed Exhibit C, "Notice of Lease", of the
      lease agreement between TR 628 Hebron Limited Partnership and BDS Business
      Center, Inc. However, the document we received does not set forth exact
      dates for lease commencement and expiration. Therefore, in order to
      finalize the lease agreement, we are sending this letter as confirmation
      that the term of the lease commenced on July 27, 1998 and shall end at
      midnight on November 26, 2004. This letter will become part of the lease
      agreement and these dates will be considered legally binding unless we
      receive an objection from you, in writing, within seven (7) days of
      receipt of this letter.

      Pro-rated monthly base rent is due in the amount of $2,446.30 for July
      1998. Beginning August 1, 1998, monthly base rent of $15,167.04 is due by
      the first of each month. Please instruct your accounting department to
      send monthly rent checks to the following address:

                         TR 628 Hebron Limited Partnership
                         c/o Cushman & Wakefield
                         P.O. Box 30412
                         Hartford, CT 06150-0412

      Please instruct your insurance agent to issue a certificate of insurance
      in compliance with the dollar amounts stipulated in your lease and with
      the Landlord and managing agent named as additional insureds. All the
      necessary information is as indicated on the following page:
