applications used by the Borrower (or its suppliers and vendors) may be unable
to recognize and perform properly date-sensitive functions involving certain
dates prior to and any date after December 31, 1999), (ii) developed a plan and
timeline for addressing the Year 2000 Problem on a timely basis, and (iii) to
date, implemented that plan in accordance with that timetable. The Borrower
reasonably believes that all computer applications (including those of its
suppliers and vendors) that are material to its business and operations will on
a timely basis be able to perform properly date-sensitive functions for all
dates before and after January 1, 2000 (that is, be "Year 2000 compliant"),
except to the extent that a failure to do so could not reasonably be expected to
have Material Adverse Effect.

               SECTION 4.14. TAXES. Borrower has properly completed and timely
filed all income tax returns it is required to file, and all Taxes, assessments,
fees and other governmental charges for periods beginning prior to the date of
this Agreement have been timely paid (or, if not yet due or being disputed in
good faith, adequate reserves therefor have been established in accordance with
GAAP) and Borrower has no liability for Taxes in excess of the amounts so paid
or reserves so established. No-deficiencies for Taxes have been claimed,
proposed or assessed by any taxing or other governmental agency or authority
against Borrower and no notice of any tax lien has been filed. There are no
pending or (to the best knowledge of Borrower) threatened audits, investigations
or claims for or relating to any liability for Taxes and there are no matters
under discussion with any governmental agency or authority which could result in
an additional material liability for Taxes.

               SECTION 4.15. FINANCIAL STATEMENTS. Borrower has provided to the
Lender complete and accurate Financial Statements, which have been prepared in
accordance with GAAP (except for the absence of footnotes and subject to normal
year-end adjustments with respect to unaudited financial statements)
consistently applied throughout the periods involved and fairly present the
financial position and results of operations of Borrower for each of the periods
covered, subject, in the case of any quarterly financial statements, to normal
year-end adjustments and the absence of notes. Borrower has no Contingent
Obligation or liability for Taxes, unrealized losses, unusual forward or
long-term commitments or long-term leases, which is not reflected in such
Financial Statements or the footnotes thereto. Since the last date covered by
such Financial Statements, there has been no sale, transfer or other disposition
by Borrower of any material part of its business or property and no purchase or
other acquisition of any business or property (including any capital stock of
any other Person) material in relation to the financial condition of Borrower at
said date. Since said date, (i) there has been no change, occurrence,
development or event which has had or could reasonably be expected to have a
Material Adverse Effect and (ii) none of the capital stock of Borrower has been
redeemed, retired, purchased or otherwise acquired for value by Borrower.

               STOCK 4.16. ACCURACY AND COMPLETENESS OF INFORMATION. All data,
reports, and information heretofore, contemporaneously, or hereafter furnished
by or on behalf of the Borrower in writing to the Lender or for purposes of or
in connection with this Agreement or any other Loan Document, or any
transaction contemplated hereby or thereby, are or will be true and accurate in
all material respects on the date as of which such data, reports, and
information are dated or certified and not incomplete by omitting to state any
material fact necessary to make such data, reports, and information not
misleading at such time. There are no facts now known to the Borrower which
individually or in the aggregate would reasonably be expected to have a
Material Adverse Effect and which have not been specified herein, in the
Financial Statements, or in any certificate, opinion, or other written
statement previously furnished by the Borrower to the Lender.

          SECTION 5. COVENANTS OF THE BORROWER.

               SECTION 5.1. EXISTENCE, ETC. The Borrower shall: (a) retain its
existence and its current yearly accounting cycle, (b) maintain in full force
and effect all licenses, bonds, franchises, leases, trademarks, patents,
contracts, and other rights necessary or desirable to the profitable conduct of
its business unless the failure to do so could not reasonably be expected to
have a Material Adverse Effect on the Borrower, (c) continue in and limit its
operations to, the same general lines of business as those presently conducted
by it, and




                                       8
<PAGE>
(d) comply with all applicable laws and regulations of any federal, state, or
local governmental authority, except for such laws and regulations the
violations of which would not, in the aggregate, have a Material Adverse Effect
on the Borrower.

               SECTION 5.2. NOTICE TO THE LENDER. As soon as possible, and in
any event within five days after the Borrower learns of the following, the
Borrower will give written notice to the Lender of the following:

               (a) any proceeding instituted or threatened to be instituted by
or against the Borrower in any federal, state, local, or foreign court or
before any commission or other regulatory body (federal, state, local, or
foreign) involving a sum, together with the sum involved in all other similar
proceedings, in excess of $100,000 in the aggregate,

               (b) any contract that us terminated or amended and which has had
or could reasonable be expected to have a Material Adverse Effect on the
Borrower;

               (c) the occurrence of any Material Adverse Change with respect
to the Borrower;

               (d) the occurrence of any Event of Default or Event or condition
which, with notice or lapse of time or both, would constitute an Event of
Default, together with a statement of the action which the Borrower has taken
or proposes to take with respect thereto;

               (e) of any discovery or determination by Borrower that any
computer application (including those of its suppliers and vendors) that is
material to its business and operations will not be Year 2000 compliant on a
timely basis, except to the extent that such failure could not reasonably be
expected to have a Material Adverse Effect;

               (f) of any material damage to, the destruction of or any other
material loss to any Collateral owned or used by Borrower other than any such
Collateral with a net book value (individually or in the aggregate) less than
$10,000 or any condemnation, confiscation or other taking, in whole or in part,
or any event that otherwise diminishes so as to render impracticable or
unreasonable the use of such Collateral owned or used by Borrower together with
the amount of the damage, destruction, loss or diminution in value;

               (g) of any copyright registration made by it, any rights
Borrower may obtain to any copyrightable works, new trademarks or any new
patentable inventions, and of any renewal or extension of any trademark
registration, or if it shall otherwise become entitled to the benefit of any
patent or patent application or trademark or trademark application; and

               (h) of the opening of any new bank account or other deposit
account, and any new securities account.

               SECTION 5.3. MAINTENANCE OF BOOKS AND RECORDS. Borrower shall (i)
maintain adequate books and records (including computer records) pertaining to
the Collateral in such detail, form and scope as is customary for companies in
similar businesses in similar situations and (ii) provide the Lender and its
agents access to the premises of Borrower at any time and from time to time
following notice, during normal business hours and upon reasonable notice under
the circumstances but in no event more than twice a year unless an Event of
Default has occurred and is continuing, and at any time on and after the
occurrence and during the existence of an Event of Default, or event or
condition which, with notice or lapse of time or both, would constitute an
Event of Default, for the purposes of (A) inspecting and verifying the
Collateral, (B) inspecting and copying (at Borrower's expense) any and all
records pertaining thereto, and (C) discussing the affairs, finances and
business of Borrower with any officer, employee or director of Borrower or with
Borrower's accountants. Borrower shall reimburse the Lender for the reasonable
travel and related expenses of the Lender's employees or, at the Lender's
option, of such outside accountants or examiners as may be retained by the
Lender to verify or inspect Collateral, records or documents of Borrower on a
regular basis or for a special inspection if the Lender deems the same
appropriate. If



                                       9
<PAGE>
the Lender's own employees are used, Borrower shall also pay therefor $600 per
person per day (or such other amount as shall represent the Lender's then
current standard charge for the same), or, if outside examiners or accountants
are used, Borrower shall also pay the Lender such reasonable sum as the Lender
may be obligated to pay as fees therefor.

               SECTION 5.4. INSURANCE. Borrower shall maintain public liability
insurance, business interruption insurance, third party property damage
insurance and replacement value insurance on its assets (including the
Collateral) under such policies of insurance, with such insurance companies, in
such amounts and covering such risks as are at all times reasonably
satisfactory to the Lender in its commercially reasonable judgment, all of
which policies covering the Collateral shall name the Lender as an additional
insured and lender loss payee in case of loss, and contain other provisions as
the Lender may reasonably require to protect fully the Lender's interest in the
Collateral and any payments to be made under such policies.

               SECTION 5.5. TAXES. The Borrower will pay, when due, all taxes,
assessments, claims, and other charges ("Taxes") lawfully levied or assessed
against the Borrower or the Collateral other than taxes that are being
diligently contested in good faith by the Borrower by appropriate proceedings
promptly instituted and for which an adequate reserve is being maintained by the
Borrower in accordance with GAAP. If any Taxes remain unpaid after the date
fixed for the payment thereof, or if any lien shall be claimed therefor, then,
without notice to the Borrower, but on the Borrower's behalf, the Lender may pay
such Taxes, and the amount thereof shall be included in the Obligations.

               SECTION 5.6. BORROWER TO DEFEND COLLATERAL AGAINST CLAIMS; FEES
ON COLLATERAL. The Borrower will defend the Collateral against all claims and
demands of all Persons at any time claiming the same or any interest therein.
The Borrower will not permit any notice creating or otherwise relating to liens
on the Collateral or any portion thereof to exist or be on file in any public
office other than Permitted Liens. The Borrower shall promptly pay, when
payable, all transportation, storage, and warehousing charges and license fees,
registration fees, assessments, charges, permit fees, and taxes (municipal,
state, and federal) which may now or hereafter be imposed upon the ownership,
leasing, renting, possession, sale, or use of the Collateral, other than taxes
on or measured by the Lender's income and fees, assessments, charges, and taxes
which are being contested in good faith by appropriate proceedings diligently
conducted and with respect to which adequate reserves are maintained to the
extent required by GAAP.

               SECTION 5.7. CHANGE OF LOCATION, STRUCTURE, OR IDENTITY. The
Borrower will give Lender at least 30 days prior written notice of any change
of Borrower's chief executive office or of the opening of any additional place
of business. The Borrower will not move or permit the movement of any item of
Collateral from the locations specified in the Schedule, except that the
Borrower keep Collateral at other locations within the United States provided
that the Borrower has delivered to the Lender (i) prior written notice thereof
and (ii) duly executed financing statements and other agreements and instruments
(all in form and substance satisfactory to the Lender) necessary or, in the
opinion of the Lender, desirable to perfect and maintain in favor of the Lender
a first priority security interest in the Collateral. Notwithstanding anything
to the contrary in the immediately preceding sentence, the Borrower may keep any
Collateral consisting of motor vehicles or rolling stock at any location in the
United States provided that the Lender's security interest in any such
Collateral is conspicuously marked on the certificate of title thereof and the
Borrower has complied with the provisions of Section 5.9.

               SECTION 5.8. USE OF COLLATERAL; LICENSES; REPAIR. The Collateral
shall be operated by competent, qualified personnel in connection with the
Borrower's business purposes, for the purpose for which the Collateral was
designed and in accordance with applicable operating instructions, laws and
government regulations, and the Borrower shall use every reasonable precaution
to prevent loss or damage to the Collateral from fire and other hazards. The
Borrower shall procure and maintain in effect all orders, licenses,
certificates, permits, approvals, and consents required by federal, state, or
local laws or by any governmental body, agency, or authority in connection with
the delivery, installation, use, and operation of the Collateral.

               SECTION 5.9. FURTHER ASSURANCES. The Borrower will, promptly
upon request by the Lender, execute and deliver or use its best efforts to
obtain any document reasonably required by the Lender



                                       10
<PAGE>
(including, without limitation, warehouseman or processor disclaimers,
mortgagee waivers, landlord disclaimers, or subordination agreements with
respect to the Obligations and the Collateral), give any notices, execute and
file any financing statements, mortgages, or other documents (all in form and
substance reasonably satisfactory to the Lender), mark any chattel paper,
deliver any chattel paper or instruments to the Lender, and take any other
actions that are necessary or, in the opinion of the Lender, desirable to
perfect or continue the perfection and the first priority of the Lender's
security interest in the Collateral, to protect the Collateral against the
rights, claims, or interests of any Persons, or to effect the purposes of this
Agreement. The Borrower hereby authorizes the Lender to file one or more
financing or continuation statements, and amendments thereto, relating to all
or any part of the Collateral without the signature of the Borrower where
permitted by law. A carbon, photographic, or other reproduction of this
Agreement or any financing statement covering the Collateral or any part
thereof shall be sufficient as a financing statement where permitted by law. To
the extent required under this Agreement, the Borrower will pay all costs
incurred in connection with any of the foregoing.

               SECTION 5.10. NO DISPOSITION OF COLLATERAL. The Borrower will
not in any way hypothecate or create or permit to exist any lien, security
interest, charge, or encumbrance on or other interest in any of the Collateral,
except for the lien and security interest granted hereby and Permitted Liens.
In the event the Collateral, or any part thereof, is sold, transferred,
assigned, exchanged, or otherwise disposed of in violation of this Agreement,
the security interest of the Lender shall continue in such Collateral or part
thereof notwithstanding such sale, transfer, assignment, exchange, or other
disposition, and the Borrower will hold the proceeds thereof in a separate
account for the benefit of the Lender. Following such a sale, the Borrower will
transfer such proceeds to the Lender in kind.

               SECTION 5.11. NO LIMITATION ON LENDER'S RIGHTS. The Borrower
will not enter into any contractual obligations which may restrict or inhibit
the Lender's rights or ability to sell or otherwise dispose of the Collateral
or any part thereof.

               SECTION 5.12. PROTECTION OF COLLATERAL. Upon notice to the
Borrower (provided that if an Event of Default has occurred and is continuing
the Lender need not give any notice), the Lender shall have the right at any
time to make any payments and do any other acts the Lender may deem necessary
to protect its security interests in the Collateral, including, without
limitation, the rights to satisfy, purchase, contest, or compromise any
encumbrance, charge, or lien which, in the reasonable judgment of the Lender,
appears to be prior to or superior to the security interests granted hereunder,
and appear in, and defend any action or proceeding purporting to affect its
security interests in, or the value of, any of the Collateral. The Borrower
hereby agrees to reimburse the Lender for all payments made and expenses
incurred under this Agreement including reasonable fees, expenses, and
disbursements of attorneys and paralegals (including the allocated costs of
in-house counsel) acting for the Lender, including any of the foregoing
payments under, or acts taken to protect its security interests in, any of the
Collateral, which amounts shall be secured under this Agreement, and agrees it
shall be bound by any payment made or act taken by the Lender hereunder absent
the Lender's gross negligence or willful misconduct. The Lender shall have no
obligation to make any of the foregoing payments or perform any of the
foregoing acts.

               SECTION 5.13. DELIVERY OF ITEMS. The Borrower will (a) promptly
(but in no event later than one Business Day) after its receipt thereof,
deliver to the Lender any documents or certificates of title issued with
respect to any property included in the Collateral, and any promissory notes,
letters of credit or instruments related to or otherwise in connection with any
property included in the Collateral, which in any such case come into the
possession of the Borrower, or shall cause the issuer thereof to deliver any of
the same directly to the Lender, in each case with any necessary endorsements
in favor of the Lender and (b) deliver to the Lender as soon as available copies
of any and all press releases and other similar communications issued by the
Borrower.

               SECTION 5.14. SOLVENCY. The Borrower shall be and remain Solvent
at all times.

               SECTION 5.15. INTELLECTUAL PROPERTY. Borrower shall do and cause
to be done all things necessary to preserve, maintain and keep in full force
and effect all of its registrations of trademarks, service marks and other
marks, trade names and other trade rights, patents, copyrights and other
intellectual property in accordance with prudent business practices, except to
the extent that the failure to preserve or maintain any of the



                                       11
<PAGE>
foregoing would not reasonably be expected to have a Material Adverse Effect.
Without limiting the generality of the foregoing, Borrower agrees promptly,
and in any event not later than 30 days after the date hereof, to have any of
its currently unregistered copyrightable software, computer programs and other
materials registered with the U.S. Copyright Office in Washington, D.C. (the
"Copyright Office") and to promptly provide TBCC with evidence of such
registration. Borrower will, on an ongoing basis, promptly register any future
unregistered copyrightable software, computer programs and other materials with
the Copyright Office.

               SECTION 5.16. FUNDAMENTAL CHANGES. The Borrower shall not (a)
amend or modify its name, unless the Borrower delivers to the Lender twenty
days prior to any such proposed amendment or modification written notice of
such amendment or modification and within ten days before such amendment or
modification delivers executed Uniform Commercial Code financing statements (in
form and substance satisfactory to the Lender) or (b) merge or consolidate with
any other entity or make any material change in its capital structure, in each
case without the Lender's prior written consent which shall not be unreasonably
withheld.

               SECTION 5.17. CONTINGENT OBLIGATIONS. Borrower will not, directly
or indirectly, incur, assume, or suffer to exist any Contingent Obligation,
excluding indemnities given in connection with this Agreement or the other Loan
Documents in favor of the Lender or in connection with the sale of inventory or
other asset dispositions permitted hereunder, except Contingent Obligations and
other similar third party credit support relating to obligations of vendors and
suppliers of Borrower in respect of transactions entered into in the normal
course of business, provided that the aggregate amount of any such guarantees
and other similar third party credit support shall not exceed $100,000 at any
time outstanding, and provided further that no Default or Event of Default shall
exist either immediately prior to or after giving effect to the making of the
foregoing guarantees or the entering into any third party credit support
transactions.

               SECTION 5.18. CHANGE IN NATURE OF BUSINESS. Borrower will not at
any time make any material change in the lines of its business as carried on at

that Borrower may enter businesses reasonably related or incidental to its
current lines of business.

               SECTION 5.19. SALES OF ASSETS. Borrower will not, directly or

               SECTION 5.20. LOANS TO OTHER PERSONS. Borrower will not at any
time make loans or advance any credit (except to trade debtors in the ordinary

credit to senior members of Borrower's management team to purchase restricted
stock of Borrower.

               SECTION 5.21. DIVIDENDS, STOCK REDEMPTIONS. Borrower will not,
directly or indirectly, pay any dividends or distributions on, purchase, redeem

outstanding ("Stock"), or make any payment on account of or set apart assets
for a sinking or other analogous fund for, the purchase, redemption,
defeasance, retirement or other acquisition of its Stock, or make any other
distribution in respect thereof, either directly or indirectly, whether in cash

to provide such financing.  Lender must reply to Borrower's notice within 15
days of the date of such notice, indicating whether Lender accepts or declines
to make such proposal.  Borrower will be required to accept Lender's proposal
if the terms and conditions of the proposal are no less favorable to Borrower
than any other proposal received by Borrower.  Subject to the foregoing Right
of First and Last Refusal, if Lender does not provide the additional financing,

be void, voidable, or invalid, or shall not be given the priority contemplated
by this Agreement; or

                                       14

          (n)  there is a change, which change results from a single
transaction or series of related transactions, but not from the sale of newly
issued securities to investors, in more than 35% of the ownership of any equity
interests of the Borrower on the date hereof or more than 35% of such interests
become subject to any contractual, judicial, or statutory lien, charge,
security interest, or encumbrance.

     SECTION 8.  REMEDIES.  If any Event of Default shall have occurred and be
continuing:

          (a)  The Lender may, without prejudice to any of its other rights
under any Loan Document or Applicable Law, declare all Obligations to be
immediately due and payable (except with respect to any Event of Default set
forth in Section 7(f) hereof, in which case all Obligations shall automatically
become immediately due and payable without necessity of any declaration)
without presentment, representation, demand of payment, or protest, which are
hereby expressly waived.

          (b)  The Lender may take possession of the Collateral and, for that
purpose may enter, with the aid and assistance of any person or persons, any
premises where the Collateral or any part hereof is, or may be placed, and
remove the same.

          (c)  The obligation of the Lender, if any, to make additional Loans
or financial accommodations of any kind to the Borrower shall immediately
terminate.

          (d)  The Lender may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein (or in any Loan
Document) or otherwise available to it, all the rights and remedies of a
secured party under the applicable Uniform Commercial Code (the "Code") whether
or not the Code applies to the affected Collateral and also may (i) require the
Borrower to, and the Borrower hereby agrees that it will at its expense and
upon request of the Lender forthwith, assemble all or part of the Collateral as
directed by the Lender and make it available to the Lender at a place to be
designated by the Lender that is reasonably convenient to both parties and
(ii) without notice except as specified below, sell the Collateral, or any part
thereof in one or more parcels at public or private sale, at any of the
Lender's offices or elsewhere, for cash, on credit, or for future delivery, and
upon such other terms as the Lender may deem commercially reasonable.

          (e)  The Lender may accelerate or extend the time of payment,
compromise, issue credits, or bring suit on all accounts receivable
("Receivables") and other Collateral (in the name of Borrower or the Lender)
and otherwise administer and collect the Receivables and other Collateral.

          (f)  The Lender may collect, receive, dispose of and realize upon any
investment property Collateral, including withdrawal of any and all funds from
any securities accounts.

          (g)  The Lender may (i) settle or adjust disputes or claims directly
with account debtors for amounts and upon terms which it considers advisable,
and (ii) notify account debtors on the Receivables and other Collateral that
the Receivables and Collateral have been assigned to the Lender, and that
payments in respect thereof shall be made directly to the Lender. If an Event
of Default has occurred and is continuing, Borrower hereby irrevocably
authorizes and appoints the Lender, or any Person the Lender may designate, as
its attorney-in-fact, at Borrower's sole cost and expense, to exercise, all of
the following powers, which are coupled with an interest and are irrevocable,
until all of the Obligations have been indefeasibly paid and satisfied in full
in cash:  (A) to receive, take, endorse, sign, assign and deliver, all in the
name of the Lender or Borrower, any and all checks, notes, drafts, and other
documents or instruments relating to the Collateral; (B) to receive, open and
dispose of all mail addressed to Borrower and to notify postal authorities to
change the address for delivery thereof to such address as the Lender may
designate; and (C) to take or bring, in the name of the Lender or Borrower, all
steps, actions, suits or proceedings deemed by the Lender necessary or desirable
to enforce or effect collection of Receivables and other Collateral or file and
sign Borrower's name on a proof of claim in bankruptcy or similar document
against any obligor of Borrower.

          (h)  The Borrower agrees that, to the extent notice of sale shall be
required by law, at

                                       15
<PAGE>
least ten days' notice to the Borrower of the time and place of any public sale
or the time after which any private sale is to be made shall constitute
reasonable notification. The Lender shall not be obligated to make any sale of
Collateral regardless of notice of sale having been given. The Lender may
adjourn any public or private sale from time to time by announcement at the
time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned. Borrower recognizes
that the Lender may be unable to make a public sale of any or all of any
investment property Collateral, by reason of prohibitions contained in
applicable securities laws or otherwise, and expressly agrees that a private
sale to a restricted group of purchasers for investment and not with a view to
any distribution thereof shall be considered a commercially reasonable sale.

          (i)  Unless expressly prohibited by any licensor thereof, the Lender
is hereby granted a license to use all computer software programs, data bases,
processes, trademarks, tradenames and materials used by Borrower in connection
with its businesses or in connection with the Collateral.

          (j)  All cash proceeds received by the Lender in respect of any
sale of, collection from, or other realization upon all or any part of the
Collateral may, in the discretion of the Lender, be held by the Lender as
collateral for, or then or at any time thereafter applied in whole or in part by
the Lender against, all or any part of the Obligations in such order as the
Lender shall elect. Any surplus of such cash or cash proceeds held by the
Lender and remaining after the full and final payment of all the Obligations
shall be paid over to the Borrower or to such other Person to which the Lender
may be required under applicable law, or directed by a court of comperent
jurisdiction, to make payment of such surplus.

         SECTION 9.  MISCELLANEOUS PROVISIONS.

               SECTION 9.1. NOTICES. Except as otherwise provided herein, all

               SECTION 9.2. HEADINGS. The headings in this Agreement are for

any provision of this Agreement.

               SECTION 9.3. ASSIGNMENTS AND PARTICIPATIONS. The Borrower shall
not have the right to assign any Note or this Agreement or any interest therein
unless the Lender shall have given the Borrower prior written consent and the
Borrower and its assignee shall have delivered assignment documentation in form
and substance satisfactory to the Lender in its sole discretion. The Lender may
assign (without the consent of Borrower) to one or more Persons all or a portion
of its rights and obligations under this Agreement and the other Loan Documents
(provided that such Person shall not be a direct or indirect competitor of the
Borrower). The Lender may sell participations in or to all or a portion of its
rights and obligations under this Agreement (including, without limitation, all
or a portion of any Loans); provided, however, that the Lender's obligations
under this Agreement shall remain unchanged. The Lender may, in connection with
any permitted assignment or participation or proposed assignment or
participation pursuant to this Agreement, disclose to the assignee or
participant or proposed assignee or participant any information relating to
Borrower furnished to the Lender by or on behalf of Borrower.

               SECTION 9.4. AMENDMENTS, WAIVERS, AND CONSENTS. Any amendment
or waiver of any provision of this Agreement and any consent to any departure
by the Borrower from any provision of this Agreement shall be effective only by
a writing signed by the Lender and shall bind and benefit the Borrower and the
Lender and their respective successors and assigns, subject, in the case of the
Borrower, to the first sentence of Section 9.3.

               SECTION 9.5. INTERPRETATION OF AGREEMENT. Time is of the
essence in each

                                       16
<PAGE>
provision of this Agreement of which time is an element. All terms not defined
herein or in a Note shall have the meaning set forth in the applicable Code,
except where the context otherwise requires. To the extent a term of provision
of this Agreement conflicts with any Note, or any term or provision thereof, and
is not dealt with herein with more specificity, this Agreement shall control
with respect to the subject matter of such term or provision. Acceptance of or
acquiescence in a course of performance rendered under this Agreement shall not
be relevant in determining the meaning of this Agreement even though the
accepting or acquiescing party had knowledge of the nature of the performance
and opportunity for objection.

     SECTION 9.6.  CONTINUING SECURITY INTEREST.  This Agreement shall create a
continuing security interest in the Collateral and shall (i) remain in full
force and effect until the indefeasible payment in full of the Obligations,
(ii) be binding upon the Borrower and its successors and assigns and (iii)
inure, together with the rights and remedies of the Lender hereunder, to the
benefit of the Lender and its successors, transferees, and assigns.

     SECTION 9.7.  REINSTATEMENT.  To the extent permitted by law, this
Agreement and the rights and powers granted to the Lender hereunder and under
the Loan Documents shall continue to be effective or be reinstated if at any
time any amount received by the Lender in respect of the Obligations is
rescinded or must otherwise be restored or returned by the Lender upon the
insolvency, bankruptcy, dissolution, liquidation, or reorganization of the
Borrower or upon the appointment of any receiver, intervenor, conservator,
trustee, or similar official for the Borrower or any substantial part of its
assets, or otherwise, all as though such payments had not been made.

     SECTION 9.8.  SURVIVAL OF PROVISIONS.  All representations, warranties, and
covenants of the Borrower contained herein shall survive the execution and
delivery of this Agreement, and shall terminate only upon the full and final
payment and performance by the Borrower of the Obligations secured hereby.

     SECTION 9.9.  INDEMNIFICATION.  The Borrower agrees to indemnify and hold
harmless the Lender and its directors, officers, agents, employees, and counsel
from and against any and all costs, expenses, claims, or liability incurred by
the Lender or such Person hereunder and under any other Loan Document or in
connection herewith or therewith, unless such claim or liability shall be due to
willful misconduct or gross negligence on the part of the Lender or such Person.
In addition and without limiting the generality of the foregoing, Borrower
shall, upon demand, pay to the Lender all reasonable costs and expenses incurred
by the Lender (including the reasonable fees and disbursements of counsel and
other professionals) in connection with the preparation, execution, delivery,
administration, modification and amendment of the Loan Documents, and pay to the
Lender all reasonable costs and expenses (including the reasonable fees and
disbursements of counsel and other professionals) paid or incurred by the Lender
in order to enforce or defend any of its rights under or in respect of this
Agreement, any other Loan Document or any other document or instrument now or
hereafter executed and delivered in connection herewith, collect the Obligations
or otherwise administer this Agreement, foreclose or otherwise realize upon the
Collateral or any part thereof, prosecute actions against, or defend actions by,
account debtors; commence, intervene in, or defend any action or proceeding;
initiate any complaint to be relieved of the automatic stay in bankruptcy; file
or prosecute any probate claim, bankruptcy claim, third-party claim, or other
claim; examine, audit, copy, and inspect any of the Collateral or any of
Borrower's books and records; protect, obtain possession of, lease, dispose of,
or otherwise enforce the Lender's security interest in the Collateral; and
otherwise represent the Lender in any litigation relating to Borrower.

     SECTION 9.10.  COUNTERPARTS; SIGNATURES BY FACSIMILE.  This Agreement may
be executed in counterparts, each of which when so executed and delivered shall
be an original, but both of which shall together constitute one and the same
instrument. This Agreement and each of the other Loan Documents and any notices
given in connection herewith or therewith may be executed and delivered by
facsimile transmission all with the same force and effect as if the same was a
fully executed and delivered original manual counterpart.

     SECTION 9.11.  SEVERABILITY.  In case any provision in or obligation
under this Agreement or any Note or any other Loan Document shall be invalid,
illegal, or unenforceable in any jurisdiction, the validity, legality, and
enforceability of the remaining provisions or obligations, or of such provision
or

                                       17


<PAGE>
obligation in any other jurisdiction, shall not in any way be affected or
impaired thereby.

     SECTION 9.12.  DELAYS; PARTIAL EXERCISE OF REMEDIES.  No delay or omission
of the Lender to exercise any right or remedy hereunder, whether before or
after the happening of any Event of Default, shall impair any such right or
shall operate as a waiver thereof or as a waiver of any such Event of
Default.  No single or partial exercise by the Lender of any right or remedy
shall preclude any other or further exercise thereof, or preclude any other
right or remedy.

     SECTION 9.13.  ENTIRE AGREEMENT.  The Borrower and the Lender agree that
this Agreement, the Schedule hereto, and the Commitment Letter are the complete
and exclusive statement and agreement between the parties with respect to the
subject matter hereof, superseding all proposals and prior agreements, oral or
written, and all other communications between the parties with respect to the
subject matter hereof.  Should there exist any inconsistency between the terms
of the Commitment Letter and this Agreement, the terms of this Agreement shall
prevail.

     SECTION 9.14.  SETOFF.  In addition to and not in limitation of all rights
of offset that the Lender may have under Applicable Law, and whether or not the
Lender has made any demand or the Obligations of the Borrower have matured, the
Lender shall have the right to appropriate and apply to the payment of the
Obligations of the Borrower all deposits and other obligations then or
thereafter owing by the Lender to or for the credit or the account of the
Borrower.

     SECTION 9.15.  JOINT AND SEVERAL LIABILITY.  If Borrower consists of more
than one Person, their liability shall be joint and several, and the compromise
of any claim with, or the release of, any Borrower shall not constitute a
compromise with, or a release of, any other Borrower.

     SECTION 9.16.  MAXIMUM RATE.  Notwithstanding anything to the contrary
contained elsewhere in this Agreement or in any other Loan Document, the
parties hereto hereby agree that all agreements between them under this
Agreement and the other Loan Documents, whether now existing or hereafter
arising and whether written or oral, are expressly limited so that in no
contingency or event whatsoever shall the amount paid, or agreed to be paid, to
the Lender for the use, forbearance, or detention of the money loaned to
Borrower and evidenced hereby or thereby or for the performance or payment of
any covenant or obligation contained herein or therein, exceed the maximum
non-usurious interest rate, if any, that at any time or from time to time may be
contracted for, taken, reserved, charged or received on the Obligations, under
the laws of the State of Illinois (or the laws of any other jurisdiction whose
laws may be mandatorily applicable notwithstanding other provisions of this
Agreement and the other Loan Documents), or under applicable federal laws which
may presently or hereafter be in effect and which allow a higher maximum
non-usurious interest rate than under the laws of the State of Illinois (or such
other jurisdiction), in any case after taking into account, to the extent
permitted by applicable law, any and all relevant payments or charges under this
Agreement and the other Loan Documents executed in connection herewith, and any
available exemptions, exceptions and exclusions (the "Highest Lawful Rate"). If
due to any circumstance whatsoever, fulfillment of any provisions of this
Agreement or any of the other Loan Documents at the time performance of such
provision shall be due shall exceed the Highest Lawful Rate, then,
automatically, the obligation to be fulfilled shall be modified or reduced to
the extent necessary to limit such interest to the Highest Lawful Rate, and if
from any such circumstance the Lender should ever receive anything of value
deemed interest by applicable law which would exceed the Highest Lawful Rate,
such excessive interest shall be applied to the reduction of the principal
amount then outstanding hereunder or on account of any other then outstanding
Obligations and not to the payment of interest, or if such excessive interest
exceeds the principal unpaid balance then outstanding hereunder and such other
then outstanding Obligations, such excess shall be refunded to Borrower.  All
sums paid or agreed to be paid to the Lender for the use, forbearance, or
detention of the Obligations and other indebtedness of Borrower to the Lender
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated and spread throughout the full term of such indebtedness, until
payment in full thereof, so that the actual rate of interest on account of all
such indebtedness does not exceed the Highest Lawful Rate throughout the entire
term of such indebtedness.  The terms and provisions of this Section shall
control every other provision of this Agreement, the other Loan Documents and
all other agreements between the parties hereto.

<PAGE>
                         SECTION 9.17. WAIVER OF JURY TRIAL. THE BORROWER AND
THE LENDER IRREVOCABLY WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING, OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY
OTHER LOAN DOCUMENT, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

                         SECTION 9.18. GOVERNING LAW, THE VALIDITY,
INTERPRETATION, AND ENFORCEMENT OF THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF ILLINOIS WITHOUT GIVING
EFFECT TO THE CONFLICT OF LAW PRINCIPLES THEREOF.


                         SECTION 9.19. VENUE; SERVICE OF PROCESS. ANY LEGAL
ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
MAY BE BROUGHT IN THE COURTS OF THE STATE OF ILLINOIS SITUATED IN COOK COUNTY,
OR OF THE UNITED STATES OF AMERICA FOR THE NORTHERN DISTRICT OF ILLINOIS, AND,
BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER HEREBY ACCEPTS FOR
ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE
JURISDICTION OF THE AFORESAID COURTS. THE BORROWER HEREBY IRREVOCABLY WAIVES,
IN CONNECTION WITH ANY SUCH ACTION OR PROCEEDING, (a) ANY OBJECTION, INCLUDING,
WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, THAT IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS AND
(b) THE RIGHT TO INTERPOSE ANY NONCOMPULSORY SETOFF, COUNTERCLAIM, OR
CROSS-CLAIM. THE BORROWER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY
OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF
COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE
BORROWER AT THE ADDRESS FOR IT SPECIFIED IN SECTION 9.1 HEREOF. NOTHING HEREIN
SHALL AFFECT THE RIGHT OF THE LENDER TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST
THE BORROWER IN ANY OTHER JURISDICTION, SUBJECT IN EACH INSTANCE TO THE
PROVISIONS HEREOF WITH RESPECT TO RIGHTS AND REMEDIES.

                         IN WITNESS WHEREOF, the undersigned Borrower has
caused this Agreement to be duly executed and delivered by its proper and duly
authorized officer as of the date first set forth above.

Collateral:                         To secure the loans, Lender will require a
                                    first priority security interest in all
                                    assets of Borrower, including intellectual
                                    property, now owned or hereafter acquired,
                                    including, but not limited to, cash,

Location of Collateral:             California

Right of First and                  If and when, during the term of the Loan,
Last Refusal:                       Borrower seeks accounts receivable and/or
                                    inventory financing, Borrower will so notify
                                    Lender and permit Lender to make a proposal
                                    to provide such financing. Lender must reply
                                    to Borrower's notice within 15 days of the
                                    date of such notice, indicating whether
                                    Lender accepts or declines to make such
                                    proposal. Borrower will be required to
                                    accept Lender's proposal if the terms and
                                    conditions of the proposal received by
                                    Borrower. Subject to the foregoing Right of
                                    First and Last Refusal, if Lender does not
                                    provide the additional financing, Lender
                                    will subordinate priority of its security
                                    interest in accounts receivable and

                         forth above as of the date each Loan Term commences
                         proportionally to the change in the weekly average of
                         the interest rates of three-year U.S. Treasury
                         Securities (as published in the Wall Street Journal)
                         from the week ending March 12, 1999 (5.10%) to the

                         of the date each Loan Term commences, the Monthly
                         Payment will be fixed for that entire Loan Term. A
                         schedule of actual monthly payment amounts will be
                         provided by the Lender following commencement of each
                         Loan Term.

Interim Payment:         An Interim Payment will accrue from the date of funding
                         each Loan until the next following first day of a month
                         (unless the Loan is funded on the first day of a
                         month). The Interim Payment will be calculated at the
                         daily equivalent of the currently adjusted Monthly
                         Payment.

Prepayment:              Borrower will have the right to prepay the Loan at any
                         time after the first 12 months of each Loan Term. The
                         amount of any prepayment will be equal to the present
                         value of the remaining payments due under the Loan
                         discounted, on a simple interest basis, at the rate of
                         6% per annum during months 13-18, 7% per annum during
                         months 19-24, and 8% per annum during months 25-36.

Warrants:                As an inducement to the Lender to provide financing on
                         the terms generally outlined herein, Borrower will
                         grant to Lender Warrants to purchase 100,000 shares of
                         common stock of the Borrower at an exercise price
                         equal to $5.50 per share. The Warrants will be
                         exercisable for a period of seven (7) years. The
                         Lender will have the option to exercise the Warrants
                         without payment of the exercise price and receive only
                         that number of shares which represents the value of
                         the difference between the fair market value of the
                         shares and the exercise price (i.e., "net issuance" or
                         "cashless exercise").

If any installment of principal or interest is not paid within five days after
its due date, the Borrower agrees to pay TBCC a late charge, in addition to the
amount of such installment, in an amount equal to 5% of such installment.

     3.   GENERAL RELEASE. In consideration for TBCC entering into this
Amendment, the Borrower hereby irrevocably releases and forever discharges TBCC,
and its successors, assigns, agents, shareholders, directors, officers,
employees, agents, attorneys, parent corporations, subsidiary corporations,
affiliated corporations, affiliates, participants, and each of them, from any
and all claims, debts, liabilities, demands, obligations, costs, expenses,
actions and causes of action, of every nature and description, known and
unknown, which Borrower now has or at any time may hold, by reason of any
matter, cause or thing occurred, done, omitted or suffered to be done prior to
the date of this Agreement (collectively, the "Released Claims"). Borrower
hereby irrevocably waives the benefits of California Civil Code Section 1542
which provides: "A general release does not extend to claims which the creditor
does not know or suspect to exist in his favor at the time of executing the
release, which if known by him must have materially affected his settlement with
the debtor." This release is fully effective on the date hereof.

     4.   REPRESENTATIONS TRUE. Borrower represents and warrants to TBCC that
all representations and warranties set forth in the Loan Documents, as amended
hereby, are true and correct, except that any representations and warranties
made as of specified earlier date shall remain true and correct as of such
earlier date unless such representations and warranties are deemed to be have
been made as of a later date and, in such eventuality, they shall remain true
and correct as of such later date.

Corporate Controller
Repeater Technologies, Inc.
1150 Morse Avenue
Sunnyvale, California 94089

Re:  Loan and Security Agreement dated July 8, 1999 executed by Repeater
Technologies, Inc. ("Repeater") and Transamerica Business Credit Corporation
("TBCC") (together with all documents and agreements executed in connection
therewith, hereinafter referred to as the "Loan Agreement"); all capitalized
terms not otherwise defined herein shall have the meanings set forth in the
Loan Agreement.

Dear Elif:

This letter shall serve as notice to Repeater Technologies, Inc. that it is in
default of its Obligations to TBCC under the Loan Agreement for the sale of
assets on or about April 1, 2001, without notice or approval, with a value of
approximately $968,000. The failure to observe this requirement of the Loan
Agreement is a default pursuant to Section 7 of the Loan Agreement.

Therefore, this letter shall serve as notice that TBCC hereby accelerates all
amounts due and owing and makes demand for all amounts due to TBCC pursuant to
the terms and conditions of the Loan Documents. The payoff amount due TBCC, as
of June 29, 2001, is $2,675,464.17.

If Repeater does not pay all such amounts in full by the close of business on
July 2, 2001, or make other arrangements satisfactory to TBCC, TBCC will seek
to enforce its rights and remedies under the Loan Documents, law and equity.

This letter is without prejudice to, and TBCC specifically reserves all of its
rights and remedies against, Repeater under the Loan Documents, law and equity.
If you would like to discuss this matter, please call me immediately.


Very truly yours,

TRANSAMERICA BUSINESS CREDIT CORPORATION
