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.
