MASTER LEASE AGREEMENT No. S7620, Dated January 27, 2000 ("Lease")

FINOVA Capital Corporation ("we", "us" or "FINOVA"), having its principal place
of business at FINOVA Corporate Center, 4800 North Scottsdale Road, Scottsdale,
Arizona 85251, agrees to lease to TRITON NETWORK SYSTEMS, INC. ("you" or
"Lessee") and you agree to lease from us, the equipment ("Equipment") described
in any schedule to this Lease (a "Schedule"). The Equipment also includes any
replacement parts, repairs, additions and accessories that you may add to the
Equipment. We may treat any Schedule as a separate lease containing all of the
provisions of this Lease.

     1.  PURCHASING AND INSTALLING THE EQUIPMENT.

     We will purchase the Equipment from (a) you directly, in the case of
     previously acquired Equipment (4 months old or newer as of the beginning of
     the Term of the applicable Schedule), or (b) the Supplier you chose. The
     Supplier will deliver the Equipment to you at your expense. You will
     properly install the Equipment at your expense at the location(s) indicated
     in the Schedule. All equipment is subject to review and acceptance by us
     prior to the beginning of the Term of the applicable Schedule.

     2.  TERM.

         (a) The Term of each Schedule begins when any of the Equipment on that
             Schedule is delivered to you, or a later date that we agree to in
             writing.

         (b) The Term continues until you fully perform all of your obligations
             under this Lease and the Schedule.

         (c) If the Equipment is not delivered, installed and accepted by you by
             the Expiration Date indicated in the Schedule, we may terminate
             this Lease and the Schedule as to the Equipment that was not
             delivered, installed and accepted by giving you 10 days written
             notice of termination.

         (d) Before we make any progress payment or final payment for the
             Equipment on any Schedule, we require the following:

             (1) That no payment is past due to us under any lease, loan or
                 other financial arrangement that you or any guarantor have with
                 us.

             (2) That you are complying with all the terms of this Lease.

             (3) That we have received all the documents we requested, including
                 the signed Schedule and Delivery and Acceptance Certificate.

             (4) That there has been no material adverse change in your
                 financial condition, business or operations from the condition
                 that you disclosed to us.

     3.  RENT.

         (a) The rent is indicated on the Schedule. The rent is payable
             periodically in advance from time to time (for example, monthly).
             You agree that you owe us the total of all of these rent payments
             over the Term of the Schedule.

         (b) The first rent payment is due at the beginning of the Term or at a
             later date that we agree to in writing. Subsequent rent payments
             are due on the same day of each successive period until you pay us
             in full all of the rent and any other charges or expenses you owe
             us.

         (c) If the first rent payment is due later than the beginning of the
             Term, you will also pay us interim rent on the first rent payment
             date. The interim rent will be for the period from the beginning of
             the Term until the date that the first rent payment is due. Interim
             rent will be calculated at the same rate as the regular rent
             payment, but on a daily basis for the number of days for which
             interim rent is due, based upon a 30 day month.

         (d) YOUR OBLIGATION TO PAY US ALL RENT IS ABSOLUTE AND UNCONDITIONAL.
             YOU ARE NOT

<PAGE>   2
             EXCUSED FROM PAYING THE RENT, IN FULL, FOR ANY REASON. YOU AGREE
             THAT YOU HAVE NO DEFENSE FOR FAILURE TO PAY THE RENT AND YOU WILL
             NOT MAKE ANY COUNTERCLAIMS OR SETOFFS TO AVOID PAYING THE RENT.

     4. NON-CANCELABLE LEASE. YOU AGREE THAT YOU MAY NOT CANCEL OR TERMINATE
        THIS LEASE OR ANY SCHEDULE.

     5. PROTECTION OF OUR INTEREST IN THE EQUIPMENT; FEES.

         (a) The Equipment is our property. It will remain our property. You
             will not own the Equipment unless the Schedule gives you an option
             to purchase the Equipment and you have exercised that option and
             paid us in full for the Equipment and any other amounts you may owe
             us. If we request, you will put labels stating "PROPERTY OF FINOVA"
             on the significant and large dollar amount items of Equipment where
             they are clearly visible.

         (b) You give us permission to add to this Lease or any Schedule the
             serial numbers and other information about the Equipment.

         (c) While this Lease is intended to be a lease (and not a loan), to
             secure all of your now existing or hereafter arising obligations to
             us, you grant us a security interest in the Equipment (and all
             accessions and additions thereto, substitutions for and
             replacements of the Equipment) and all proceeds of the foregoing,
             including, without limitation, insurance proceeds, to protect our
             interest in the Equipment. If this Lease is later determined to be
             a security agreement. This security interest will be a first
             security interest covering the Equipment. You give us permission to
             file this Lease or Uniform Commercial Code financing statements, at
             your expense, in order to perfect this security interest. You also
             give us permission to sign your name on the Uniform Commercial
             Code financing statements where this is permitted by law.

         (d) You will pay our costs and reasonable fees for documentation,
             closing, administration and termination of this Lease. These fees
             include such items as reasonable attorneys fees and expenses
             incurred in preparing this Lease and all amendments, supplements
             and waivers hereto, as well as due diligence searches and fees for
             preparing and filing UCC terminations and releases. You will also
             pay any filing, recording or stamp fees or taxes resulting from
             filing this Lease or Uniform Commercial Code financing statements.

         (e) At your expense, you will defend our ownership rights in the
             Equipment against, and keep the Equipment free of, any legal
             process, liens, attachments, levies and executions. You will give
             us immediate written notice of any legal process, liens,
             attachments, levies or executions, and you will indemnify us
             against any loss that results to us from these causes.

         (f) You will notify us at least 15 days before you change the address
             of your principal executive office.

         (g) You will notify us at least 15 days before you change your state of
             incorporation.

         (h) You will promptly sign and return additional documents that we may
             request in order to protect our interest in the Equipment.

         (i) The Equipment is personal property and will remain personal
             property. You will not incorporate it into real estate and will not
             do anything that will cause the Equipment to become part of real
             estate or a fixture.

     6. CARE, USE, LOCATION AND ALTERATION OF THE EQUIPMENT.

         (a) You will make sure that the Equipment is maintained in good
             operating condition, and that it is serviced and repaired when this
             is necessary to keep the Equipment in good operating condition. All
             maintenance must be done according to the Supplier's or
             Manufacturer's requirements or recommendations. All maintenance
             must also comply with any legal or regulatory requirements.

         (b) You will maintain service logs for the Equipment, if applicable,
             and permit us and our agents to inspect the Equipment, the

                                       2

<PAGE>   3
             service logs and service reports. You give us and our agents
             permission to make copies of the service logs and service reports.

         (c) We will give you prior notice if we, or our agents, want to
             inspect the Equipment or the service logs or service reports. We
             may inspect it during regular business hours. If we find during an
             inspection that you are not complying with this Lease or if you
             are otherwise in default under this Lease, you (and not us) will
             pay our travel, meals, and lodging costs, our salary costs, and
             our costs and fees and those of our agents for inspection. You
             will promptly cure any problems with the Equipment that are
             discovered during our inspections.

         (d) You will use the Equipment only for business purposes. You will
             obey all legal and regulatory requirements in your use of the
             Equipment.

         (e) You will make all additions, modifications and improvements to the
             Equipment that are required by law or government regulation.
             Otherwise, you will not alter the Equipment without our written
             permission. You will replace all worn, lost, stolen, or destroyed
             parts of the Equipment with replacement parts that are as good or
             better than the original parts. The new parts will become our
             property upon replacement.

         (f) You will not remove the Equipment from the location indicated in
             the Schedule without our prior written permission.

         (g) You will not convey, assign, sell, mortgage, transfer, encumber,
             pledge, hypothecate, grant a first security interest in, grant
             options with respect to, lease or otherwise dispose of all or any
             part of any interest whatsoever in or to any or all of the
             Equipment or the location indicated in the Schedule, or any
             interest therein.

     7.  RETURN OF EQUIPMENT. Unless otherwise stated in the Schedule:

         (a) You must give us written notice at least 120 days before the end
             of the Term if you want to purchase the Equipment from us.

         (b) You must give us written notice at least 120 days before the end
             of the Term if you want to return the Equipment to us.

         (c) If you do not give us written notice at least 120 days before the
             end of the Term either that you want to purchase or that you want
             to return the Equipment, you will continue to rent the Equipment
             and this Lease and the Schedule will be automatically extended
             for a term of three (3) months and continue thereafter on a month
             to month basis until 120 days after we receive your notice. The
             rent will be the same monthly rental, subject to adjustment, as
             stated in the Schedule, including applicable sales and use taxes.

         (d) If you do give us 120 days written notice that you want to
             purchase the Equipment but you do not pay us the purchase price,
             you will continue to rent the Equipment. The rent will be the same
             monthly rental, subject to adjustment, as stated in the Schedule,
             including applicable sales and use taxes. You will continue to pay
             us this rent until you have paid the purchase price for the
             Equipment. The rent payments will not be credited to the purchase
             price.

         (e) If you do give us 120 days written notice that you want to return
             the Equipment to us, but you do not return the Equipment in
             compliance with the return conditions contained in the next
             paragraph, you will continue to rent the Equipment. The rent will
             be the same monthly rental, subject to adjustment, as stated in
             the Schedule, including applicable sales and use taxes. You will
             continue to pay us this rent until you have returned the Equipment
             to us in compliance with these return conditions.

         (f) Return conditions: - You will return the Equipment, freight and
             insurance prepaid by you, to us at a location we request in the
             continental United States of America. It will be returned in good
             operating condition normal wear and tear excepted, as required by
             Section 6 above. The Equipment will not be subject to any liens
             when it is returned, and

             (1) You will pack or crate the Equipment for shipping in the
             original containers, or comparable ones. You will do this
             carefully and follow all

                                       3

<PAGE>   4
         recommendations of the Supplier and the Manufacturer as to packing or
         crating.

         (2)    You will also return to us the plans, specifications, operating
         manuals, software documentation, discs, warranties and other documents
         furnished by the Manufacturer or Supplier. You will also return to us
         all service logs and service reports, as well as all written materials
         that you may have concerning the maintenance and operation of the
         Equipment.

         (3)    At our request, you will provide us with up to 60 days free
         storage of the Equipment at your location, and will let us (or our
         agent) have access to the Equipment in order to inspect it, display it
         to others for purchase and sell it.

         (4)    You will pay us what it costs us to repair the Equipment if you
         do not return it in the required condition.

    8.   RISK OF LOSS.

         (a)    You have the complete risk of loss or damage to the Equipment.
                Loss or damage to the Equipment will not relieve you of your
                obligation to pay rent.

         (b)    If any Equipment is lost or damaged, you have two choices
                (although if you are in default under this Lease, we and not you
                will have the two options).
                The choices are:

                (1)    Repair or replace the damaged or lost Equipment so that,
                once again, we own Equipment in good operating condition and
                have clear title to it.

                (2)    Pay us the present value (as of the date of payment) of
                the remaining rent payments and our residual interest in the
                Equipment. We will calculate the present value using a discount
                rate of five (5%) percent per year. Once you have paid us this
                amount and any other amount that you may owe us, you (or your
                insurer) may keep the Equipment for salvage purposes, on an "AS
                IS, WHERE IS" basis.

    9.   INSURANCE.

         (a)    Until you have properly returned the Equipment to us, you will
                keep it insured. The amount of the insurance, the coverage, and
                the insurance company must be acceptable to us.

         (b)    If you do not provide us with written evidence of insurance that
                is acceptable to us, we may buy the insurance ourselves, at your
                expense. You will promptly pay us the cost of this insurance. We
                have no obligation to purchase any insurance. Any insurance that
                we purchase will be our insurance, and not yours, and we may
                insure the Equipment beyond the end of the Term.

         (c)    Insurance proceeds may be used to repair or replace damaged or
                lost Equipment or to pay us the present value of the rent and
                our residual interest in the Equipment. (See Section 8, "Risk of
                Loss", above).

         (d)    You appoint us as your "attorney-in-fact" to make claims under
                the insurance policies, to receive payments under the insurance
                policies, and to endorse your name on all documents, checks or
                drafts relating to insurance claims for Equipment.

    10.  TAXES.

         (a)    You will pay all sales, use, excise, stamp, documentary and ad
                valorum taxes, license and registration fees, assessments,
                fines, penalties and similar charges imposed on the ownership,
                possession, use or lease of the Equipment.

         (b)    You will pay all taxes (other than our federal or state net
                income taxes) imposed on you or on us or the rent payments.

                                       4
<PAGE>   5
        (c) You will reimburse us for any of these taxes that we pay or advance.

        (d) Unless we notify you otherwise, we will file and pay for any
            personal property taxes on the Equipment. You will reimburse us for
            the full amount of these taxes, without regard to early payment
            discount. We may estimate the amount of these taxes in advance and
            bill you periodically in advance for these taxes.

    11. INDEMNITY.

        (a) You will indemnify us, defend us and hold us harmless. This applies
            to any and all claims, expenses and attorney's fees concerning or
            arising from the Equipment, this Lease, or any Schedule. It includes
            any claims concerning the manufacture, selection, delivery,
            possession, use, operation or return of the Equipment.

        (b) This obligation of yours to indemnify us continues even after the
            Term is over.

    12. DEFAULT.

    You are in default if any of the following happens:

        (a) You do not pay us, when it is due, any rent payment or other payment
            that you owe us under this Lease, any Schedule, or any other lease,
            loan or other financial arrangement that you have with us.

        (b) Any of the financial information that you give us is not true and
            complete, or you fail to tell us anything that would make the
            financial information not misleading.

        (c) You do something you are not permitted to do, or you fail to do
            anything that is required of you, under this Lease, any Schedule
            or any other lease, loan or other financial arrangement that you
            have with us.

        (d) An event of default occurs under any other lease, loan or obligation
            of yours that exceeds $100,000 in the aggregate and continues beyond
            any applicable grace period provided therein unless the default is
            being contested in good faith.

        (e) You file bankruptcy or involuntary bankruptcy is filed against you
            and such involuntary bankruptcy is not dismissed within 60 days.

        (f) You are subject to any other insolvency proceeding other than
            bankruptcy (for example, a receivership action or an assignment for
            benefit of creditors) and such proceeding that is involuntary is not
            dismissed within 60 days.

        (g) Without our permission, you sell all or a substantial part of your
            assets, merge or consolidate, or a majority of your voting stock or
            interests is transferred. However, you may, without violating the
            provisions of this clause, consolidate with or merge with a
            corporation or other entity organized under the laws of one of the
            states of the United States or the District of Columbia (the
            surviving entity, a "successor", or sell (except by means of a sale
            and leaseback arrangement) all or substantially all of its business
            and assets to a transferee (the "transferee"), on the condition that
            any successor or transferee either expressly or by operation of law
            assume in writing all of your obligations pursuant to this Lease,
            and that the net tangible assets and the net worth (determined in
            accordance with generally accepted accounting principles) of the
            successor or transferee after the consolidation, merger or sale
            shall be at least equal to your net tangible assets, as the case may
            be, immediately prior to the consolidation, merger or sale.

                                       5
<PAGE>   6
          (h)  There is a material adverse change in your financial condition,
               business or operations.

13.  REMEDIES, DEFAULT INTEREST, LATE FEES.

If you are in default we may exercise one or more of our "remedies." Each of
our remedies is independent. We may exercise any of our remedies, all of our
remedies or none of our remedies. We may exercise them in any order we choose.
Our exercise of any remedy will not prevent us from exercising any other remedy
or be an "election of remedies." If we do not exercise a remedy, or if we delay
in exercising a remedy, this does not mean that we are forgiving your default
or that we are giving up our right to exercise the remedy. Our remedies allow
us to do one or more of the following:

          (a)  Require you to immediately pay us all rent for the entire Term
               for any or all Schedules.

          (b)  Require you to immediately pay us all amounts that you are
               required to pay us for the entire Term of any other leases, loans
               or other financial arrangements that you have with us.

          (c)  Sue you for all rent and other amounts you owe us plus the
               greater of (1) the actual residual value of the Equipment or (2)
               the residual value we assumed when we leased it to you. Future
               rent and residual value will be discounted to present value using
               a discount rate of five (5%) percent per year.

          (d)  Require you at your expense to return the Equipment and to comply
               with all of the terms of Section 7(f) hereof.

          (e)  Exercise any remedy under the Uniform Commercial Code or as
               otherwise permitted by law, including, without limitation, to the
               extent permitted, retaking and removing the Equipment. We have
               your permission to remove any physical obstructions to removal of
               the Equipment. We may also disconnect and separate all Equipment
               from other property. You will not be entitled to any damages
               resulting from removal or repossession of the Equipment. We may
               use, ship, store, repair or lease any Equipment that we
               repossess. We may sell any repossessed Equipment at private or
               public sale. You give us permission to show the Equipment to
               buyers at your location free of charge during normal business
               hours. If we do this, we do not have to remove the Equipment from
               your location. If we repossess the Equipment and sell it, we will
               give you a credit for the net sale price, after subtracting our
               costs of repossessing and selling the Equipment. If we rent the
               Equipment to somebody else, we will give you credit for the net
               rent received, after subtracting our costs of repossessing and
               renting the Equipment, but the credit will be discounted to
               present value using the discount rate that we used in calculating
               your rental payment under the Schedule for the Equipment. The
               credit will be applied against what you owe us under this Lease,
               the Schedules and any other leases, loans or other financial
               arrangements that you have with us. If the credit exceeds the
               amount you owe under this lease, the Schedules and any other
               leases, loans or other financial arrangements that you have with
               us, we will refund the amount of the excess to you.

          (f)  We will have all of our rights and remedies under this Lease, the
               Schedules and all agreements, instruments and documents executed
               in connection herewith and therewith and all of our rights and
               remedies under applicable law, whether as a secured party or
               otherwise.

          (g)  You will also pay us the following:

               (1)  All our expenses of enforcing our remedies. This

                                       6
<PAGE>   7
             includes all our expenses to repossess, store, ship, repair and
             sell the Equipment.

             (2) Our reasonable attorney's fees and expenses.

             (3) Default interest on everything you owe us from the date of your
             default to the date on which we are paid in full. The "default
             interest rate" will be one and one-half (1.5%) percent per month.
             If this interest rate exceeds the highest legal interest rate, you
             will only be required to pay us default interest at the highest
             legal interest rate.

         (h) You realize that the damages we could suffer as a result of your
             default are very uncertain. You also realize that the value of an
             unexpired lease Term is difficult or impossible to calculate. This
             is why we have agreed with you in advance on the discount rates and
             default interest rate to be used in calculating the payments you
             will owe us if you default. You agree that, for these reasons, the
             payments you will owe us if you default are "agreed" or
             "liquidated" damages. You understand that these payments are not
             "penalties" or "forfeitures."

         (i) You will pay us a late fee whenever you pay any amount that you owe
             us more than 10 days after it is due. You will pay the late fee
             within one month after the late payment was originally due. The
             late fee will be seven (7%) percent of the late payment. If this
             exceeds the highest legal amount we can charge you; you will only
             be required to pay the highest legal amount. The late fee is
             intended to reimburse us for our collection costs that are caused
             by late payment. It is charged in addition to all other amounts you
             are required to pay us, including default interest. However, no new
             late fee will be charged during any period that default interest is
             charged.

     14. PERFORMING YOUR OBLIGATIONS IF YOU DO NOT.

     If you do not perform one or more of your obligations under this Lease or
     Schedule, we may perform it for you. We will notify you in writing at least
     10 days before we do this. We do not have to perform any of your
     obligations for you. If we do choose to perform them, you will pay us all
     of our expenses to perform the obligations. You will also reimburse us for
     any money that we advance to perform your obligations, together with
     interest at the default interest rate on that amount. This will be
     additional "rent" that you will owe us and you will pay it at the same time
     that your next rent payment is due.

     15. INFORMATION SUPPLIED BY YOU.

         (a) You have supplied us with information about the Equipment. You
             promise to us that the amount we are paying for the Equipment is no
             more than the fair and usual price for this kind of Equipment,
             taking into account any discounts, rebates and allowances that you
             or any affiliate of yours may have been given for the Equipment.

         (b) During the Term you will promptly provide us with copies of any
             current, quarterly and annual reports and all proxy (or
             information) statements you file with the Securities and Exchange
             Commission (SEC).

         (c) You will also provide us with the following financial statements:

             (1) Quarterly balance sheet and statements of earnings and cash
             flow, within 45 days after the end of your first three fiscal
             quarters in each fiscal year. These will be certified by the chief
             financial officer.

             (2) Annual balance sheet and statements of earnings and cash flow,
             within 90 days after the end of each fiscal year. These will be

                                       7
<PAGE>   8
             audited by independent auditors from a national accounting firm
             (the "Big Five"). Their audit report must be unqualified.

             All financial statements will be prepared according to generally
             accepted accounting principles, consistently applied. All
             financial statements and SEC filings that you provide us will be
             true and complete. They will not fail to tell us anything that
             would make them not misleading.

         (d) At the same time you deliver the financial statements described in
             paragraphs 15(c)(1) and (2), you will also provide us with a
             certificate of your chief financial officer stating that no
             default exists, or, if he cannot certify this because a default
             does exist, he must specify in reasonable detail the nature of the
             default.

     16. COVENANT.

     You shall take all action necessary to assure that there will be no
     material adverse change to your business by reason of the advent of the
     year 2000, including, without limitation, that all computer-based systems,
     embedded microchips and other processing capabilities effectively
     recognize and process all dates after December 31, 1999. At our request,
     you shall provide to us assurance reasonably acceptable to us that your
     computer-based systems, embedded microchips and other processing
     capabilities are year 2000 compatible.

     17. REPRESENTATIONS AND WARRANTS.

             condition, business or operations, from the financial condition,
             business or operations that you disclosed to us.

         (c) You have complied with all "environmental laws" and will continue
             to comply with all "environmental laws." No "hazardous substances"
             are used, generated, treated, stored or disposed of by you or at
             your properties except in compliance with all environmental laws.

8529 Southpark Circle, Orlando, FL 32819, in one or more advances made from
time to time (individually, an "Advance" and collectively, the "Advances"), in
the aggregate principal amount of up to FIVE MILLION AND 00/100 Dollars
($5,000,000.00), under the terms and conditions contained in this Master Loan
and Security Agreement (this "Master Agreement"). The entire Loan will be
"cross collateralized" and secured by the collateral (the "Collateral")
described in each schedule (individually, a "Schedule" and collectively,
"Schedules") which will be executed in connection with each Advance and the
related Note (as hereinafter defined). The Collateral includes the Equipment
hereinafter described and any and all replacement parts, additions, accessories
and accessions that you may add to the Equipment, as well as all replacements
and substitutions of the Equipment and all proceeds of the Equipment,
including, without limitation, insurance proceeds. We may treat any Schedule as
a separate loan and security agreement containing all of the provisions of this
Master Agreement.

1. THE CREDIT

   (A) ADVANCES. Each Advance shall be evidenced by and the specific terms
applicable thereto set forth in a Note and related Schedule. All of the Notes
and Schedules, taken together, will evidence the entire Loan. We will only make
the Loan to you if all the conditions in this Master Agreement have been met to
our satisfaction. We will rely on your representations and warranties contained
in this Master Agreement, in making the Loan. The terms of this Master Agreement
will each apply to the entire Loan.

   (B) USE OF PROCEEDS. The proceeds of the Advances will be used solely to
reimburse you for your payment of the purchase price for equipment which is
satisfactory to us and which is described in the applicable Schedule
("Equipment"). If you have not yet paid for the Equipment (but the same is
otherwise satisfactory to us), the proceeds of the Advance will be paid by us
directly to the supplier (which you have chosen) to pay the purchase price of
the Equipment.

   (C) NOTES. Your obligation to repay the Advance and to pay interest thereon
will be evidenced by separate secured promissory notes
<PAGE>   2
    (individually, a "Note" and collectively, the "Notes"). Each Note will be
    dated the date of the Schedule to which the Advance evidenced by the Note is
    related. The related Schedule will be deemed to be part of the Note.

         (D) TERM. The term ("Term") of each Schedule (and the related Advance)
    begins upon the date that we make payment for the Collateral covered under
    the Schedule (the "Closing Date"). The Term continues until you fully
    perform all of your obligations under this Master Agreement, each related
    Schedule and the related Notes(s).

         (E) LOAN ACCOUNT. We will keep a loan account on our books and records
    for the Loan. We will record all payments of principal and interest in the
    loan account. Unless the entries in the loan account are clearly in error,
    the loan account will definitively indicate the outstanding principal
    balance and accrued interest on the Loan.

         (F) PAYMENTS. The scheduled payments of principal and interest (the
    "Payments") are indicated on and due and payable in accordance with the
    terms of the applicable Note and Schedule. The Payments are payable in
    advance and otherwise on the dates and in the amounts set forth on the
    applicable Schedule.

         (G) FIRST PAYMENT AND SUBSEQUENT PAYMENTS. The first Payment under a
    Note and Advance ("First Payment") is due at the beginning of its Term and
    shall, at our option, either be deducted from the proceeds of the Advance or
    paid directly to us by you. Subsequent Payments are due on the thirtieth
    (30th) day of each successive month as set forth on the Schedule until you
    pay to us in full all of the Payments and any other fees, costs, charges and
    expenses that you owe us.

         (H) INTEREST. Prior to Maturity of an Advance, you will pay us interest
    on the Advance at the interest rate indicated in the applicable Schedule
    (the "Interest Rate"). "Maturity" means the scheduled maturity or any
    earlier date on which we accelerate the Loan. The Payment amount indicated
    in the Schedule includes interest at the applicable Interest Rate. Interest
    is calculated in advance using a year of 360 days with twelve months of 30
    days.

         (I) INTERIM INTEREST PAYMENT. If any Advance is made on a day other
    than the thirtieth (30th) or thirty-first (31st) day of a month, you will
    also pay to us, together with the First Payment, interest on the Advance at
    the applicable interest rate for the period from the date the Advance is
    made until the twenty-ninth (29th) day of the month in which the Advance is
    made. If an Advance is made on the thirty-first (31st) day of a month, you
    will also pay to us, together with the First Payment, interest on the
    Advance at the applicable interest rate for the period from the date the
    Advance is made until the twenty-ninth (29th) day of the following month. If
    an Advance is made on the thirtieth (30th) day of a month, no interim
    interest will be due.

         (J) DEFAULT INTEREST RATE. After Maturity of the Loan or any Advance,
    you will pay us interest thereon at a rate of three (3%) percent per year
    above the applicable Interest Rate. This is referred to as the "Default
    Rate."

         (K)  USURY. You and we intend to obey the law. If the Interest Rate
    charged would exceed the maximum legal rate, you will only have to pay the
    maximum legal rate. You do not have to pay any excess interest over and
    above the maximum legal rate of interest. However, if it later becomes legal
    for you to pay all or part of any excess interest, you will then pay it to
    us upon our request.

         (L) PAYMENT DETAILS. You will make all Payments due under this Master
    Agreement by 12:00 P.M., Connecticut time, on the day they are due. You will
    make all Payments in US Dollars (US$) in immediately available funds. We do
    not have to make or give "presentment, demand, protest or notice" to get
    paid. You waive "presentment, demand, protest and notice."

         (M) APPLICATION OF PAYMENTS. Each Payment under this Master Agreement
    is to be applied in the following order: first, to any fees, costs, expenses
    and charges you may owe us;

                                       2
<PAGE>   3
     second, to any interest due; and third to the principal balance.

       (N) PREPAYMENT. You may prepay the Loan as specifically permitted by
     Exhibit B to the applicable Schedule.

       (O) NO SETOFFS. Your obligation to pay us all Payments is absolute and
     unconditional. You are not excused from making the Payments, in full, for
     any reason. You agree that you have no defense for failure to make the
     Payments and you will not make any counterclaims or setoffs to avoid making
     the Payments.

     2.  SECURITY INTEREST

       (a) You grant us a first lien on and security interest in the Collateral.
     The Collateral secures the full and timely payment and performance of all
     of your now existing or hereafter arising indebtedness, liabilities and
     obligations to us, whether under this Master Agreement, the Schedules, the
     Notes and any other agreement, loan or lease that you may at any time or
     times have with us or otherwise (collectively, the "Obligations"). You also
     grant us a security interest in any additional collateral identified in any
     Schedule. Any additional collateral is considered to be "Collateral" and it
     secures all of the Obligations.

       (b) If we request, you will put labels supplied by us stating "PROPERTY
     SUBJECT TO A SECURITY INTEREST HELD BY FINOVA CAPITAL CORPORATION" on
     significant and large dollar amount items of Collateral where they are
     clearly visible.

       (c) You give us permission to add to this Master Agreement or any
     Schedule the serial numbers and other information about the Collateral.

       (d) You give us permission to file this Master Agreement or Uniform
     Commercial Code financing statements, at your expense, in order to perfect
     our security interest in the Collateral. You also give us permission to
     sign you name on the Uniform Commercial Code financing statements where
     this is permitted by law.

       (e) You will pay our reasonable costs and fees for documentation,
     closing, administration and termination of this Master Agreement, the Notes
     and Schedules. These fees include such items as reasonable attorneys fees
     and expenses incurred in preparing this Master Agreement and all
     agreements, instruments and documents executed in connection herewith, and
     all amendments, supplements and waivers hereto and thereto, as well as due
     diligence searches and fees for preparing and filing UCC terminations and
     releases. You will also pay any filing, recording or stamp fees or taxes
     resulting from filing this Master Agreement or Uniform Commercial Code
     financing statements.

       (f) At your expense, you will defend our first priority security interest
     in the Collateral against, and keep the Collateral free of, any legal
     process, liens, attachments, levies and executions. You will give us
     immediate written notice of any legal process, liens, attachments, levies
     or executions, and you will indemnify us against any loss that results to
     us from these causes.

       (g) You will notify us at least 15 days before you change the address of
     your principal executive office or principal place of business. Your
     principal executive office and principal place of business are set forth at
     the beginning of this Master Agreement.

       (h) You will notify us at least 15 days before you change your state of
     incorporation.

       (i) You will promptly sign and return additional documents that we may
     reasonably request in order to protect our first priority security interest
     in the Collateral.

       (j) Except as set forth in a Schedule, the Collateral is personal
     property and will remain personal property. Except as set forth in a
     Schedule, you will not incorporate it into real estate and will not do
     anything that will cause the Collateral to become part of real estate or a
     fixture.

     3.  CONDITIONS OF LENDING

                                       3

     consider to be a part of this Master Agreement. The terms and conditions
     of the Commitment Letter continue following the making of the first
     Advance, including, without limitation, conditions to the Loan. However,
     if there is a conflict between the terms and conditions of this Master
     Agreement, any Schedule or any Note and the terms and conditions of the
     Commitment Letter, then you and we agree that the terms and conditions of
     this Master Agreement, the Schedules and the Notes control over the
     Commitment Letter terms and conditions.

         (b) Before we disburse any proceeds of any Advance, we also require
     the following:

             (i) That no payment is past due to us under any other agreement,
     loan or lease that you have with us.

             (ii) That you are complying with all terms of this Master
     Agreement, the Schedules and the Notes and there are no defaults hereunder

     including the signed Schedule and Note.

     satisfied.

     granted a first perfected lien on and security interest in all of the
     Collateral.

         (e) You have supplied us with information about the Collateral. You
     promise to us that the amount of our Advance as to each item of Equipment
     is no more than the fair and usual price for this kind of Equipment,
     taking into account any discounts, rebates and allowances that you or any
     affiliate of yours may have been given for the Equipment.

         (g) All financial information and other information that you have given

         processing capabilities effectively recognize and process dates after
         December 31, 1999.

         5.  COVENANTS

         You agree to do the following things (or not to do the following things
         if so stated) until full payment of all amounts due to us under this
         Master Agreement, the Schedules and the Notes:

              (A) CARE, USE, LOCATION, TRANSFER, ENCUMBRANCE AND ALTERATION OF
         THE COLLATERAL.

              (i) You will make sure that the Collateral is maintained in good
         operating condition, and that it is serviced, repaired and overhauled
         when this is necessary to keep the Collateral in good operating
         condition, normal wear and tear excepted. All maintenance must be done
         according to the Supplier's or Manufacturer's requirements or
         recommendations. All maintenance must also comply with any legal or
         regulatory requirements.

              (ii) You will maintain service logs for Collateral, if applicable,
         and permit us or our agents to inspect the Collateral, the service logs
         and service reports. You give us and our agents permission to make
         copies of the service logs and service reports.

              (iii) We will give you prior notice if we, or our agents, want to
         inspect the Collateral or the service logs or service reports. We may
         inspect it during regular business hours. If we find during an
         inspection that you are not complying with this Master Agreement or if
         you are otherwise in default under this Master Agreement, you (and not
         us) will pay our travel, meals and lodging costs, our salary costs, and
         our costs and fees and those of our agents for reinspection. You will
         promptly cure any problems with the Collateral that are discovered
         during our inspections.

              (iv) You will use the Collateral only for business purposes. You
         will obey all legal and regulatory requirements in your use of the
         Collateral.

              (v) You will make all additions, modifications and improvements to
         the Collateral that are required by law or government regulation.
         Otherwise, you will not alter the Collateral without our written
         permission. You will replace all worn, lost, stolen or destroyed parts
         of the Collateral with replacement parts that are as good or better
         than the original parts. The new parts will become subject to our
         security interest upon replacement.

              (vi) You will not remove the Collateral from the location
         indicated in the Schedule without our prior written permission.

              (vii) You have and will have good and merchantable title to all of
         the Collateral.

              (viii) You will not convey, assign, sell, mortgage, transfer,
         encumber, pledge, hypothecate, grant a first security interest in,
         grant options with respect to, lease or otherwise dispose of all or any
         part of any interest whatsoever in or to any or all of the Collateral,
         or any interest therein.

              (B) YEAR 2000 COMPLIANT.

         You shall take all action necessary to assure that there will be no
         material adverse change to your business by reason of the advent of the
         year 2000, including, without limitation, that all computer-based
         systems, embedded microchips and other

                                       5
<PAGE>   6
processing capabilities effectively recognize and process all dates after
December 31, 1999. At our request, you shall provide to us assurance reasonably
acceptable to us that your computer-based systems, embedded microchips and
other processing capabilities are year 2000 compatible.

     (C)  RISK OF LOSS.

          (i) You have the complete risk of loss or damage to the Collateral.
Loss or damage to the Collateral will not relieve you of your obligation to make
the Payments.

          (ii) If any Collateral is lost or damaged, you have two choices
although if you are in default under this Master Agreement, we and not you will
have the two options. The choices are:

          (A) Repair or replace the damaged or lost Collateral so that, once
again, the Collateral is in good operating condition and we have a perfected
first priority security interest in it.

          (B) Pay us the present value (as of the date of payment) of the
remaining Payments. We will calculate the present value using a discount rate of
five (5%) percent per year. Once you have paid us this amount and any other
amount that you may owe us, we will release our security interest in the damaged
or lost Collateral and you (or your insurer) may keep the Collateral for salvage
purposes, on an "AS IS, WHERE IS" basis and without any representation or
warranty whatsoever.

     (D) INSURANCE.

          (i) Until you have made all Payments to us under this Master
Agreement, the Schedules and the Notes and all Obligations have been satisfied
in full, you will keep the Collateral insured. The amount of insurance, the
coverage, and the insurance company must be acceptable to us.

          (ii) If you do not provide us with written evidence of insurance that
is acceptable to us, we may buy the insurance ourselves, at your expense. You
will promptly pay us the cost of this insurance. We have no obligation to
purchase any insurance. Any insurance that we purchase will be our insurance,
and not yours, and we may insure the Collateral beyond the date of satisfaction
of the Obligations.

          (iii) Insurance proceeds may be used to repair or replace damaged or
lost Collateral or to pay us the present value of the Payments, as provided
above.

          (iv) You appoint us as your "attorney-in-fact" to make claims under
the insurance policies, to receive payments under the insurance policies, and to
endorse your name on all documents, checks or drafts relating to insurance
claims for Collateral.

     (E) TAXES.

          (i) You will pay all sales, use, excise, stamp, documentary and ad
valorum taxes, license, recording and registration fees, assessments, fines,
penalties and similar charges imposed on the ownership, possession, use, lease
or rental of the Collateral or on the Loan.

          (ii) You will pay all taxes (other than our federal or state net
income taxes) imposed on you or on us regarding the Payments.

          (iii) You will reimburse us for any of these taxes that we pay or
advance.

          (iv) You will file and pay for any personal property taxes on the
Collateral.

     (F) INFORMATION SUPPLIED BY YOU.

          (i) During the Term you will promptly provide us with copies of any
current, quarterly and annual reports and all proxy (or information) statements
you file with the Securities and Exchange Commission ("SEC").

          (ii) You will also provide us with the following financial statements:

          (A) Quarterly balance sheet and statements of earnings and cash flow -
within 45 days after the end of your first three fiscal

                                       6
<PAGE>   7
quarters in each fiscal year. These will be certified by the chief financial
officer.

     (B) Annual balance sheet and statements of earnings and cash flow - within
90 days after the end of each fiscal year. These will be audited by independent
auditors from a national accounting firm ("Big Five"). Their audit report must
be unqualified.

All financial statements will be prepared according to generally accepted
accounting principles, consistently applied. All financial statements and SEC
filings that you provide us will be true and complete. They will not fail to
tell us anything that would make them not misleading.

     (iii) At the same time you deliver the financial statements described in
paragraph 5(f)(ii)(A) and (B), you will also provide us with a certificate of
your chief financial officer stating that no default exists, or, if he cannot
certify this because a default does exist, he must specify in reasonable detail
the nature of the default.

     6. DEFAULTS

     (A) DEFAULTS. You are in default if any of the following happens:

         (i) You do not pay us, when it is due, any Payment or other payment
that you owe us under this Master Agreement, any Schedule or any Note or that
you owe under any other agreement, loan, lease or other financial arrangement
that you have with us.

         (ii) Any of the financial information that you give us is not true and
complete, or you fail to tell us anything that would make the financial
information not misleading.

         (iii) You do something you are not permitted to do, or you fail to do
anything that is required of you, under this Master Agreement, any Schedule or
any other lease, loan or other financial arrangement that you have with us.

         (iv) An event of default occurs for any other lease, loan or obligation
of yours that exceeds $100,000 in the aggregate and continues beyond any
applicable grace period provided therein unless the default is being contested
in good faith.

         (v) You file bankruptcy or involuntary bankruptcy is filed against you
and such involuntary bankruptcy is not dismissed within sixty (60) days.

         (vi) You are subject to any other insolvency proceeding other than
bankruptcy (for example, a receivership action or an assignment for the benefit
of creditors) and such proceeding that is involuntary is not dismissed within
sixty (60) days.

         (vii) Without our permission, you sell all or a substantial part of
your assets, merge or consolidate, or a majority of your voting stock or
interests is transferred. However, you may, without violating the provisions of
this clause, consolidate with or merge with a corporation or other entity
organized under the laws of one of the states of the United States or the
District of Columbia (the surviving entity, a "successor", or sell (except by
means of a sale and leaseback arrangement) all or substantially all of its
business and assets to a transferee (the "transferee"), on the condition that
any successor or transferee either expressly or by operation of law assume in
writing all of your obligations pursuant to this Master Agreement, and that the
net tangible assets and the net worth (determined in accordance with generally
accepted accounting principles) of the successor or transferee after the
consolidation, merger or sale shall be at lease equal to your net tangible
assets, as the case may be, immediately prior to the consolidation, merger or
sale.

         (viii) There is a material adverse change in your financial condition,
business or operations.

     (B) REMEDIES, DEFAULT INTEREST, LATE FEES.

         If you are in default we may exercise one or more of our "remedies."
Each of our remedies is independent. We may exercise any of our remedies, all of
our remedies or none of our remedies. We may exercise them in any order we

                                       7
<PAGE>   8
    choose. Our exercise of any remedy will not prevent us from exercising any
    other remedy or be an "election of remedies." If we do not exercise a
    remedy, or if we delay in exercising a remedy, this does not mean that we
    are forgiving your default or that we are giving up our right to exercise
    the remedy. Our remedies allow us to do one or more of the following:

         (i) "Accelerate" the Loan balance under any or all Notes. This means
    that we may require you to immediately pay us the entire outstanding
    principal balance of the entire Loan.

         (ii) Require you to immediately pay us all amounts that you are
    required to pay us for the entire Term of any other agreements, loans,
    leases or financial arrangements that you have with us.

         (iii) Sue you for the entire outstanding principal balance of the Loan
    and all other amounts you owe us (including, without limitation, all accrued
    and unpaid interest, including interest at the Default Rate), outstanding
    fees, costs, expenses and charges, plus all prepayment premiums.

         (iv) Require you at your expense to assemble the Collateral at a
    location we occupy or you occupy within the United States of America.

         (v) Exercise any remedy under the Uniform Commercial Code or otherwise
    permitted by law including to the extent permitted retaking and removing the
    Collateral. If required, we may disconnect and separate the Collateral from
    your other property. You will not be entitled to any damages resulting from
    removal or repossession of the Collateral. We may use, ship, store, repair
    or lease any Collateral that we repossess. We may sell any repossessed
    Collateral at private or public sale. You give us permission to show the
    Collateral to buyers at your location free of charge during normal business
    hours. If we do this, we do not have to remove the Collateral from your
    location. If we repossess the Collateral and sell it, we will give you
    credit for the net sale price, after subtracting our costs of repossessing
    and selling the Collateral. If we rent the Collateral to somebody else, we
    will give you credit for the net rent received, after subtracting our costs
    of repossessing and renting the Collateral, but the credit will be
    discounted to present value using a discount rate equal to the Default Rate.
    The credit will be applied against what you owe us under this Master
    Agreement, the Schedules, the Notes and any other agreements, loans, leases
    and other financial arrangements that you have with us. If the credit
    exceeds the amount you owe under this Master Agreement, the Schedule, the
    Notes and any other agreements, loans, leases or financial arrangements that
    you have with us, we will refund the amount of the excess to you.

         (vi) We will have all of our rights and remedies under this Master
    Agreement, the Notes, the Schedules and all agreements, instruments and
    documents executed in connection herewith and therewith and all of our
    rights and remedies under applicable law, whether as a secured party or
    otherwise.

         (vii) Return conditions:

         (A) Following a default, at our request you will return the Collateral,
    freight and insurance prepaid by you, to us at a location we request in the
    continental United States of America. It will be returned in good operating
    condition, as required by Section 5 above. The Collateral will not be
    subject to any liens when it is returned.

         (B) You will pack or crate the Collateral for shipping in the original
    containers, or comparable ones. You will do this carefully and follow all
    recommendations of the Supplier and the Manufacturer as to packing or
    crating.

         (C) You will also return to us the plans, specifications, operating
    manuals, software, documentation, discs, warranties and other documents
    furnished by the Manufacturer or Supplier. You will also return to us all
    service logs and service reports, as well as all written materials that you
    may have concerning the maintenance and operation of the Collateral.

         (D) At our request, you will provide us with up to 60 days free storage
    of the Collateral at your location, and will let us (or our agent) have

                                       8
<PAGE>   9
access to the Collateral in order to inspect it, display it to others for
purchase and sell it.

     (E) You will pay us what it costs us to repair the Collateral if you do
not return it in the required condition, only when the condition is not part of
ordinary wear and tear.

     (viii) You will also pay us the following:

     (A) All our expenses of enforcing our remedies. This includes all our
expenses to repossess, store, ship, repair and sell the Collateral.

     (B) Our reasonable attorney's fees and expenses.

     (C) Default interest on everything you owe us from the date of your default
to the date on which we are paid in full at the Default Rate.

     (D) A premium in the amount equal to the prepayment premium as set forth
in Exhibit B to the applicable Schedule.

     (ix) You will pay us a late fee whenever you pay any amount that you owe
us more than ten (10) days after it is due. You will pay the late fee within
one month after the late Payment was originally due. The late fee will be seven
(7%) percent of the late Payment. If this exceeds the highest legal amount we
can charge you, you will only be required to pay the highest legal amount. The
late fee is intended to reimburse us for our collection costs that are caused
by late Payment. It is charged in addition to all other amounts you are
required to pay us, including Default Interest. However, no new late fee will
be charged during any period that Default Interest is being charged.

     (x) You realize that the damages we could suffer as a result of your
default are very uncertain. This is why we have agreed with you in advance on
the Default Rate to be used in calculating the payments you will owe us if you
default. You agree that, for these reasons, the payments you will owe us if you
default are "agreed" or "liquidated" damages. You understand that these
payments are not "penalties" or "forfeitures."

7.   PERFORMING YOUR OBLIGATIONS IF YOU DO NOT

If you do not perform one or more of your obligations under this Master
Agreement or a Schedule or Note, we may perform it for you. We will notify you
in writing at least ten (10) days before we do this. We do not have to perform
any of your obligations for you. If we do choose to perform them, you will pay
us all of our expenses to perform the obligations. You will also reimburse us
for any money that we advance to perform your obligations, together with
interest at the Default Rate on that amount. These will be additional "Payments"
that you will owe us and you will pay them at the same time that your next
Payment is due.

8.   INDEMNITY

(a)  You will indemnify us, defend us and hold us harmless from and against any
ana all claims, expenses and attorney's fees concerning or arising from the
Collateral, this Master Agreement, any Schedule or Note, or your breach of any
representation, warranty or covenant. It includes, without limitation, any
claims, losses or charges concerning, arising out of or in connection with the
manufacture, selection, delivery, possession, use, operation or return of the
Collateral and any claims, losses or damages concerning, arising out of or in
connection with this Master Agreement, any Schedule or the Notes.

     (b) This obligation of yours to indemnify us continues even after the
Term is over.
