3.       THE PURCHASER'S REPRESENTATIONS AND WARRANTIES.

         Each Purchaser severally and not jointly represents and warrants to the
Company as follows:

         a. Purchase for Own Account. The Purchaser is purchasing the Shares for
the Purchaser's own account and not with a present view towards the distribution
thereof. The Purchaser understands that the Purchaser must bear the economic
risk of this investment, unless the Common Stock underlying the Shares (i) is
registered pursuant to the Securities Act and any applicable state securities or
blue sky laws or an exemption from such registration is available, and (ii) the
Shares are converted into Common Stock pursuant to the terms of the Certificate
of Designation. Notwithstanding anything in this Section 3(a) to the contrary,
by making the foregoing representation, the Purchaser does not agree to hold the
Shares, or the Common Stock underlying the Shares, for any minimum or other
specific term and reserves the right to dispose of the Shares, or the Common
Stock underlying the Shares, at any time in accordance with or pursuant to a
registration statement or an exemption from registration under the Securities
Act and any applicable state securities laws; provided, that in the case of any
transfer of the Shares, or the Common Stock underlying the Shares, pursuant to
an exemption, such transfer is made in accordance with the provisions of Section
3(e).

         b. Information. The Purchaser has been furnished all materials
(excluding any material nonpublic information) relating to the business,
finances and operations of the Company and its Subsidiaries and materials
relating to the offer and sale of the Shares that have been requested by the
Purchaser. The Purchaser has been afforded the opportunity to ask questions of
the Company.

         c. Governmental Review. The Purchaser understands that no United States
federal or state agency or any other government or governmental agency has
passed upon or made any recommendation or endorsement of the Shares.

         d. Authorization; Enforcement. The Purchaser has the requisite power
and authority to enter into and perform its obligations under this Agreement and
to purchase the Shares in accordance with the terms hereof. This Agreement has
been duly and validly authorized, executed and delivered on behalf of the
Purchaser and is a valid and binding agreement of the Purchaser enforceable
against the Purchaser in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
other laws affecting creditors' rights and remedies generally and

                                       3

<PAGE>

to general principles of equity (regardless of whether enforcement is sought in
a proceeding at law or in equity).

         e. Transfer or Resale. The Purchaser understands that (i) except as
provided in Section 5(h) hereof, the Shares, and the Common Stock underlying the
Shares, have not been and are not being registered under the Securities Act or
any state securities laws, and may not be transferred unless (a) subsequently
registered thereunder or sold pursuant to Rule 144 under the Securities Act, or
(b) the Purchaser shall have delivered to the Company an opinion of counsel
reasonably acceptable to the Company (which opinion shall be in form, substance
and scope customary for opinions of counsel in comparable transactions) to the
effect that the Shares, or the Common Stock underlying the Shares, to be sold or
transferred may be sold or transferred under an exemption from such
registration.

         f. Legends. The Purchaser understands that the Shares, and upon any
conversion of the Shares to Common Stock, the Common Stock underlying the
Shares, may bear a restrictive legend in substantially the following form:

                  NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE
                  SECURITIES ARE CONVERTIBLE HAVE BEEN REGISTERED WITH THE
                  SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES
                  COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM
                  REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                  "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE OF THE
                  UNITED STATES. THE SECURITIES REPRESENTED HEREBY MAY NOT BE
                  OFFERED OR SOLD IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
                  STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS
                  UNLESS OFFERED, SOLD OR TRANSFERRED UNDER AN AVAILABLE
                  EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS.
                  NOTWITHSTANDING THE FOREGOING, THESE SECURITIES AND THE
                  SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES MAY BE
                  PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER
                  FULL RECOURSE LOAN OR FINANCING ARRANGEMENT SECURED BY SUCH
                  SECURITIES.

          Certificates evidencing Shares shall not be required to contain such
legend or any other legend (i) while a registration statement covering the
resale of the Common Stock underlying the Shares is effective under the
Securities Act provided the Purchasers at the time any of the Purchasers request
a removal of the Legend on any certificate evidencing all or any portion of the
Shares or to transfer any of the same (or a broker acting on such Purchaser's
behalf) provides to the Company (or to the Transfer Agent on the Company's
behalf) reasonable written assurances to the effect that any of the Shares sold
or to be sold by such Purchasers have been, or will be, sold in accordance with
the plan of distribution set forth in the prospectus and in compliance with the
prospectus delivery requirements under the Securities Act, or (ii) following any
sale of such Shares, or assuming

                                       4

<PAGE>

conversion of the Shares, the Common Stock underlying the Shares, pursuant to
Rule 144, or (iii) if such Shares, or assuming conversion, the Common Stock
underlying the Shares, are eligible for sale under Rule 144(k), or (iv) if such
legend is not required under applicable requirements of the Securities Act
(including judicial interpretations and pronouncements issued by the Staff of
the SEC). Following such time as a legend is no longer required for certain
Shares, or the Common Stock underlying the Shares assuming conversion, the
Company will no later than three (3) Business Days following the delivery by a
Purchaser to the Company or the Transfer Agent of a legended certificate
representing such Shares, or assuming conversion, the Common Stock underlying
the Shares, deliver or cause to be delivered to such Purchaser a certificate
representing such Shares, or assuming conversion, the Common Stock underlying
the Shares, that is free from all restrictive and other legends. The Company may
not make any notation on its records or give instructions to any transfer agent
of the Company that enlarge the restrictions on transfer set forth in this
Section 3(f).

          The Company acknowledges and agrees that a Purchaser may from time to
time pledge or grant a security interest in some or all of the Shares, or
assuming conversion, the Common Stock underlying the Shares, in connection with
a bona fide margin agreement or other full recourse loan or financing
arrangement secured by the Shares, or assuming conversion, the Common Stock
underlying the Shares, and if required under the terms of such agreement, loan
or arrangement, such Purchaser may transfer pledged or secured Shares, or the
Common Stock underlying the Shares, to the pledgees or secured parties. Such a
pledge or transfer would not be subject to approval of the Company and no legal
opinion of the pledgee, secured party or pledgor shall be required in connection
therewith, but such legal opinion may be required in connection with a
subsequent transfer following default by the Purchaser transferee of the pledge.
Further, no notice shall be required of such pledge. At the appropriate
Purchaser's expense, the Company will execute and deliver such reasonable
documentation as a pledgee or secured party of Shares, or assuming conversion,
the Common Stock underlying the Shares, may reasonably request in connection
with a pledge or transfer of the Shares, or assuming conversion, the Common
Stock underlying the Shares, including the preparation and filing of any
required prospectus supplement under Rule 424(b)(3) of the Securities Act or
other applicable provision of the Securities Act to appropriately amend the list
of selling stockholders thereunder.

         g. Investor Status. The Purchaser is an "ACCREDITED INVESTOR" within
the meaning of Rule 501 Regulation D under the Securities Act. In the normal
course of its business, it invests in or purchases securities similar to the
Shares and it has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of purchasing the
Shares.

         h. Restricted Securities. The Purchaser understands that the Shares are
characterized as "restricted securities" under the U.S. federal securities laws
inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under such laws and applicable regulations
such securities may be resold without registration under the Securities Act only
in certain limited circumstances.

4.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company represents and warrants to each Purchaser as follows:

                                       5

<PAGE>

         a. Organization and Qualification. Each of the Company and its
Subsidiaries is a corporation duly organized and existing under the laws of the
jurisdiction in which it is incorporated, and has the requisite corporate power
to own its properties and to carry on its business as now being conducted. Each
of the Company and its Subsidiaries is duly qualified as a foreign corporation
to do business and is in good standing in every jurisdiction in which the nature
of the business conducted by it makes such qualification necessary and where the
failure so to qualify would have a Material Adverse Effect. The Company has no
direct or indirect Subsidiaries other than those listed in Schedule 4(a). Except
as disclosed in Schedule 4(a), the Company owns, directly or indirectly, all of
the capital stock or comparable equity interests of each Subsidiary free and
clear of any Lien, and all the issued and outstanding shares of capital stock or
comparable equity interests of each Subsidiary are validly issued and are fully
paid, non-assessable and free of preemptive and similar rights.

         b. Authorization; Enforcement. (i) The Company has the requisite
corporate power and authority to enter into and perform its obligations under
this Agreement, to issue and sell the Shares in accordance with the terms hereof
and to issue Common Stock upon exercise of the Shares in accordance with the
terms of the Certificate of Designation; (ii) the execution, delivery and
performance of this Agreement by the Company and the consummation by it of the
transactions contemplated hereby and thereby (including, without limitation, the
reservation for issuance and issuance of the Shares and the reservation for
issuance and issuance of the Common Stock issuable upon conversion of the Shares
in accordance with the Certificate of Designation) have been duly authorized by
the Company's Board of Directors and no further consent or authorization of the
Company, its Board of Directors or its shareholders is required; (iii) this
Agreement has been duly executed and delivered by the Company; and (iv) this
Agreement constitutes a valid and binding obligation of the Company enforceable
against the Company in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
other laws affecting creditors' rights and remedies generally and to general
principles of equity (regardless of whether enforcement is sought in a
proceeding at law or in equity).

         c. Capitalization. The capitalization of the Company as of the date
hereof is set forth on Schedule 4(c), including the authorized capital stock,
the number and type or class of shares issued and outstanding, the number of
shares issuable and reserved for issuance pursuant to the Company's stock option
plans, the number of shares issuable and reserved for issuance pursuant to
securities exercisable for, or convertible into or exchangeable for any shares
of capital stock. All of such outstanding shares of the Company's capital stock
have been, or upon issuance will be, validly issued, fully paid and
nonassessable. Except as set forth on Schedule 4(c), no shares of capital stock
of the Company (including, but not limited to, the Shares and the Common Stock)
or any of the Subsidiaries are subject to preemptive rights or any other similar
rights of the shareholders of the Company or any Liens or encumbrances. Except
for the Shares and as disclosed in Schedule 4(c), as of the date of this
Agreement, (i) there are no outstanding options, warrants, scrip, rights to
subscribe to, calls or commitments of any character whatsoever to which the
Company or any of its Subsidiaries is a party relating to the issuance by the
Company or any of its Subsidiaries of securities or rights convertible into or
exercisable or exchangeable for any shares of capital stock of the Company or
any of its Subsidiaries, or arrangements by which the Company or any of its
Subsidiaries is or may become bound to issue additional shares of capital stock
of the Company or such Subsidiaries, and (ii) there are no agreements or
arrangements under which the Company or any of its Subsidiaries is obligated to
register the sale of any of its or their securities under the Securities

                                       6

<PAGE>

Act (except pursuant to Section 5(h) hereof). Except as set forth on Schedule
4(c), there are no securities or instruments containing anti-dilution or similar
provisions that may be triggered by the issuance of the Shares in accordance
with the terms of this Agreement and the holders of the securities and
instruments listed on such Schedule 4(c) have waived any rights they may have
under such anti-dilution or similar provisions in connection with the issuance
of the Shares in accordance with the terms of this Agreement. The Company has
made available to each Purchaser true and correct copies of the Company's
Articles of Incorporation as in effect on the date hereof ("ARTICLES OF
INCORPORATION"), the Company's By-laws as in effect on the date hereof (the
"BY-LAWS"), the Certificate of Designation and all other instruments,
certificates of designation and agreements governing securities convertible into
or exercisable or exchangeable for capital stock of the Company, except for
stock options granted under any benefit plan of the Company.

         d. Issuance of Shares. The Shares are duly authorized and when issued
and paid for in accordance with the terms hereof, will be validly issued, fully
paid and non-assessable, and free from all taxes and Liens (other than those
imposed through acts or omissions of the Purchaser thereof) and will not be
subject to preemptive rights or other similar rights of shareholders of the
Company. The Common Stock issuable to the Purchaser upon conversion of the
Shares is duly authorized and reserved for issuance, and, upon conversion of the
Shares in accordance with the terms of the Certificate of Designation, will be
validly issued, fully paid and non-assessable and free from all taxes and Liens
(other than those imposed through acts or omissions of the Purchaser thereof)
and will not be subject to preemptive rights or other similar rights of
shareholders of the Company.

         e. No Conflicts. The execution, delivery and performance of this
Agreement by the Company, and the consummation by the Company of the
transactions contemplated hereby (including, without limitation, the reservation
for issuance and issuance of the Shares and the issuance of the Common Stock
upon conversion of the Shares) will not (i) conflict with or result in a
violation of the Articles of Incorporation or By-laws or (ii) conflict with, or
constitute a default (or an event which, with notice or lapse of time or both,
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of any agreement, indenture or
instrument to which the Company or any of its Subsidiaries is a party, or result
in a violation of any law, rule, regulation, order, judgment or decree
(including (assuming the accuracy of the representations and warranties of the
Purchasers) the United States federal and state securities laws and regulations)
applicable to the Company or any of its Subsidiaries or by which any property or
asset of the Company or any of its Subsidiaries is bound or affected (except,
with respect to clause (ii), for such conflicts, defaults, terminations,
amendments, accelerations, cancellations and violations as would not,
individually or in the aggregate, have a Material Adverse Effect). Neither the
Company nor any of its Subsidiaries is in violation of its Articles of
Incorporation, By-laws and other organizational documents and neither the
Company nor any of its Subsidiaries is in default (and no event has occurred
which, with notice or lapse of time or both, would put the Company or any of its
Subsidiaries in default) under, nor has there occurred any event giving others
(with notice or lapse of time or both) any rights of termination, amendment,
acceleration or cancellation of, any agreement, indenture or instrument to which
the Company or any of its Subsidiaries is a party, except for actual or possible
violations, defaults or rights as would not, individually or in the aggregate,
have a Material Adverse Effect. The businesses of the Company and its
Subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any governmental entity, except for actual or possible violations,
if any, the sanctions for which either singly or in the aggregate would

                                       7

<PAGE>

not have a Material Adverse Effect. Except as specifically contemplated by this
Agreement and as required under the Securities Act and any applicable state
securities laws and assuming the accuracy of the representations and warranties
of the Purchasers, the Company is not required to obtain any consent, approval,
authorization or order of, or make any filing or registration with, any court or
governmental agency or any regulatory or self regulatory agency in order for it
to execute, deliver or perform any of its obligations under this Agreement
(including without limitation the issuance and sale of the Shares as provided
hereby) in accordance with the terms hereof.

         f. SEC Documents; Financial Statements; Certain Arrangements.

                  (i) Since October 1, 2002, the Company has timely filed all
reports, schedules, forms, statements and other documents required to be filed
by it with the SEC pursuant to the Securities Exchange Act of 1934, as amended
(the "EXCHANGE ACT"), and has filed all registration statements and other
documents required to be filed by it with the SEC pursuant to the Securities Act
(all of the foregoing filed prior to the date hereof, and all exhibits included
therein and financial statements and schedules thereto and documents
incorporated by reference therein, being hereinafter referred to herein as the
"SEC DOCUMENTS"). The Company has made publicly available via the SEC's
Electronic Data Gathering, Analysis and Retrieval (EDGAR) system true and
complete copies of the SEC Documents. As of their respective dates, the SEC
Documents complied in all material respects with the requirements of the
Exchange Act or the Securities Act, as the case may be, and the rules and
regulations of the SEC promulgated thereunder applicable to the SEC Documents,
and none of the SEC Documents, at the time they were filed with the SEC,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Any statements made in any such SEC Documents that are or were
required to be updated or amended under applicable law have been so updated or
amended. As of their respective dates, the financial statements of the Company
included in the SEC Documents complied in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC
applicable with respect thereto. Such financial statements have been prepared in
accordance with United States generally accepted accounting principles,
consistently applied, during the periods involved (except in the case of
unaudited interim statements, to the extent they may not include footnotes or
may be condensed or summary statements) and fairly present in all material
respects the consolidated financial position of the Company and its Subsidiaries
as of the dates thereof and the results of their operations and cash flows for
the periods then ended (subject, in the case of unaudited statements, to normal
and recurring year-end audit adjustments). Except as set forth in the SEC
Documents, the Company has no liabilities, contingent or otherwise, other than
(i) liabilities incurred in the ordinary course of business subsequent to the
date of such SEC Documents and (ii) obligations under contracts and commitments
incurred in the ordinary course of business and not required under generally
accepted accounting principles to be reflected in such SEC Documents, which
liabilities and obligations referred to in clauses (i) and (ii), individually or
in the aggregate, would not have a Material Adverse Effect.

                  (ii) The Company does not have any "off-balance sheet
arrangements." For purposes of the preceding sentence, "OFF-BALANCE SHEET
ARRANGEMENT" means with respect to any Person, any securitization transaction to
which it is party and any other transaction, agreement or other contractual
arrangement to which an entity unconsolidated with that Person is a party, under
which it, whether or not a party to the arrangement, has, or in the future may
have: (a) any obligation under a

                                       8

<PAGE>

direct or indirect guarantee or similar arrangement; (b) a retained or
contingent interest in assets transferred to an unconsolidated entity or similar
arrangement; (c) derivatives to the extent that the fair value thereof is not
fully reflected as a liability or asset in the financial statements; or (d) any
obligation or liability, including a contingent obligation or liability, to the
extent that it is not fully reflected in the financial statements (excluding the
footnotes thereto) (for this purpose, obligations or liabilities that are not
fully reflected in the financial statements (excluding the footnotes thereto)
include, without limitation: (i) obligations that are not classified as a
liability according to generally accepted accounting principles; (ii) contingent
liabilities as to which, as of the date of the financial statements, it is not
probable that a loss has been incurred or, if probable, is not reasonably
estimable; or (iii) liabilities as to which the amount recognized in the
financial statements is less than the reasonably possible maximum exposure to
loss under the obligation as of the date of the financial statements, but
exclude contingent liabilities arising out of litigation, arbitration or
regulatory actions (not otherwise related to off-balance sheet arrangements)).
Schedule 4(f)(ii) identifies all outstanding guarantees, letters of credit,
performance bonds, assurance bonds, surety agreements, indemnity agreements and
any other legally binding forms of assurance or guaranty in connection with the
business of the Company.

         g. Absence of Certain Changes. Since the date of the latest audited
financial statements included within the SEC Documents, except as specifically
disclosed in the SEC Documents, (i) there has been no event, occurrence or
development that, individually or in the aggregate, has had or that could result
in a Material Adverse Effect, (ii) the Company has not incurred any liabilities
(contingent or otherwise) other than (A) trade payables and accrued expenses
incurred in the ordinary course of business consistent with past practice and
(B) liabilities not required to be reflected in the Company's financial
statements pursuant to generally accepted accounting principles or required to
be disclosed in filings made with the SEC, (iii) the Company has not altered its
method of accounting or the identity of its auditors, (iv) the Company has not
declared or made any dividend or distribution of cash or other property to its
stockholders or purchased, redeemed or made any agreements to purchase or redeem
any shares of its capital stock, and (v) the Company has not issued any equity
securities to any officer, director or Affiliate, except pursuant to existing
Company stock option and stock purchase plans.

         h. Absence of Litigation. Except as disclosed in the SEC Documents,
there is no action, suit, proceeding, inquiry or investigation before or by any
court, public board, government agency, self-regulatory organization or body
pending or, to the knowledge of the Company, threatened against or affecting the
Company, or any of its Subsidiaries, or any of their directors or officers in
their capacities as such which would have a Material Adverse Effect.

         i. Intellectual Property. The Company and each of its Subsidiaries owns
or is licensed to use all patents, patent applications, trademarks, trademark
applications, trade names, service marks, copyrights, copyright applications,
licenses, permits, know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures) and
other similar rights and proprietary knowledge (collectively, "INTANGIBLES")
necessary for the conduct of its business as now being conducted and as proposed
to be conducted. Except as disclosed in the SEC Documents, neither the Company
nor any of its Subsidiaries has received written notice that it is infringing
upon or in conflict with any third party Intangibles. Except as disclosed in the
SEC Documents, neither the Company nor any of its Subsidiaries has entered into
any consent, indemnification, forbearance to sue or settlement agreements with
respect to the validity

                                       9

<PAGE>

of the Company's or such Subsidiary's ownership or right to use its Intangibles.
The Intangibles are valid and enforceable, and, without the Company intending to
allow such result, no registration relating thereto has lapsed, expired or been
abandoned or canceled or is the subject of cancellation or other adversarial
proceedings, and all applications therefor are pending and in good standing. The
Company has complied with its contractual obligations relating to the protection
of the Intangibles used pursuant to licenses with such exceptions that would not
and will not have a Material Adverse Effect. To the Company's knowledge, no
Person is infringing on or violating the Intangibles owned or used by the
Company.

         j. Environment. Except as disclosed in the SEC Documents (i) there is
no environmental liability, nor factors likely to give rise to any environmental
liability, affecting any of the properties of the Company or any of its
Subsidiaries that, individually or in the aggregate, would have a Material
Adverse Effect and (ii) neither the Company nor any of its Subsidiaries has
violated any environmental law applicable to it now or previously in effect,
other than such violations or infringements that, individually or in the
aggregate, have not had and will not have a Material Adverse Effect.

         k. Title. The Company and each of its Subsidiaries has good title in
fee simple to all real property and good title to all personal property owned by
it which is material to its business, free and clear of all liens, encumbrances
and defects except for such defects in title that, individually or in the
aggregate, would not have a Material Adverse Effect. Any real property and
facilities held under lease by the Company or any of its Subsidiaries are held
by the Company or such Subsidiary under valid, subsisting and enforceable leases
with such exceptions which have not had and will not have a Material Adverse
Effect.

         l. Insurance. Except as disclosed in the SEC Documents, the Company and
its Subsidiaries maintain such insurance relating to their business, operations,
assets, key-employees and officers and directors as is appropriate to their
business, assets and operations, in such amounts and against such risks as are
customarily carried and insured against by owners of comparable businesses,
assets and operations, and such insurance coverage will be continued in full
force and effect to and including the Closing Date other than insurance coverage
in respect of which the failure to continue in full force and effect would not
reasonably be expected to have a Material Adverse Effect.

         m. No Brokers. No brokerage or finder's fees or commissions are or will
be payable by the Company to any broker, financial advisor or consultant,
finder, placement agent, investment banker, bank or other Person with respect to
the transactions contemplated by this Agreement and the Company has not taken
any action that would cause any Purchaser to be liable for any such fees or
commissions.

         n. Tax Status. The Company and each of its Subsidiaries has made or
filed all material federal, state and local income and all other tax returns,
reports and declarations required by any jurisdiction to which it is subject
(unless and only to the extent that the Company or the applicable Subsidiary has
set aside on its books provisions adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and has set aside on its books provisions adequate for the payment of all taxes
for periods subsequent to the periods to which such returns, reports or

                                       10
<PAGE>

declarations apply. There are no material unpaid taxes claimed to be due by the
taxing authority of any jurisdiction. The Company has not executed a waiver with
respect to any statute of limitations relating to the assessment or collection
of any federal, state or local tax. None of the Company's tax returns have been
or is being audited by any taxing authority.

         o. No General Solicitation. Neither the Company nor to the knowledge of
the Company any Person participating on the Company's behalf in the transactions
contemplated hereby has conducted any "general solicitation" or "general
advertising" as such terms are used in Regulation D, with respect to any of the
Shares being offered hereby.

         p. Securities Laws. Neither the Company, nor any Affiliate of the
Company, nor any Person acting on its behalf or on behalf of such Affiliate,
has, directly or indirectly, made any offers or sales of any security or
solicited any offers to buy any security under circumstances that would require
registration of the Shares being offered hereby under the Securities Act or
cause this offering of Shares to be integrated with any prior offering of
securities of the Company for purposes of the Securities Act. Assuming the truth
and accuracy of the Purchasers' representations and warranties, the offer, sale
and delivery of shares of Common Stock upon exercise of the Shares will be
exempt from the registration requirements of Section 5 of the Securities Act.

         q. Form S-3 Eligibility. The Company is currently eligible to register
the resale of its Common Stock on a registration statement on Form S-3 under the
Securities Act. The Company is not aware of any facts or circumstances
(including without limitation any required approvals or waivers of any
circumstances that may delay or prevent the obtaining of accountant's consents)
that would prohibit or delay the preparation and filing of a registration
statement on Form S-3 with respect to the Shares.

         r. Disclosure. All disclosure provided to the Purchasers regarding the
Company, its business and the transactions contemplated hereby, including the
SEC Documents and the Schedules to this Agreement, furnished by or on behalf of
the Company or filed with the SEC are true and correct and do not contain any
untrue statement of a material fact or omit to state any material fact necessary
in order to make the statements made therein, in the light of the circumstances
under which they were made, not misleading. No event or circumstance has
occurred or information exists with respect to the Company or any of its
Subsidiaries or its or their business, properties, prospects, operations or
financial conditions, which, under applicable law, rule or regulation, requires
public disclosure or announcement by the Company but which has not been so
publicly announced or disclosed. The Company acknowledges and agrees that no
Purchaser makes or has made any representations or warranties with respect to
the transactions contemplated hereby other than those specifically set forth in
Section 3.

         s. Internal Accounting Controls. The Company and the Subsidiaries
maintain a system of internal accounting controls sufficient to provide
reasonable assurance that (i) transactions are executed in accordance with
management's general or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles consistently applied and to maintain
asset accountability, (iii) access to assets is permitted only in accordance
with management's general or specific authorization, and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

                                       11

<PAGE>

         t. Transactions With Affiliates and Employees. Except as set forth on
Schedule 4(v), none of the officers or directors of the Company and, to the
knowledge of the Company, none of the employees of the Company is presently a
party to any transaction with the Company or any Subsidiary (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner. Since October 1, 2002, the Company has not (i) extended or maintained
credit, arranged for the extension of credit, or renewed an extension of credit,
in the form of a personal loan to or for any director or executive officer (or
equivalent thereof) of the Company, or (ii) materially modified any term of any
such extension or maintenance of credit. Schedule 4(v) identifies any loan or
extension of credit maintained by the Company or any of its Subsidiaries to
which the second sentence of Section 13(k)(1) of the Exchange Act applies.

5.       COVENANTS AND OTHER AGREEMENTS.

         a. Satisfaction of Conditions. The parties shall use their reasonable
efforts to satisfy in a timely manner each of the conditions set forth in
Section 6 and Section 7 of this Agreement.

         b. Form D; Blue Sky Laws. The Company agrees to file a Form D with
respect to the Shares as required under Regulation D and to provide a copy
thereof to each Purchaser promptly after such filing. The Company shall, on or
before the Closing Date, take such action as the Company shall reasonably
determine is necessary to qualify the Shares for sale to the Purchasers pursuant
to this Agreement under applicable securities or "blue sky" laws of the states
of the United States or obtain exemption therefrom, and shall provide evidence
of any such action so taken to each Purchaser on or prior to the Closing Date.

         c. Reporting Status. So long as a Purchaser beneficially owns any
Shares or has the right to acquire any Shares pursuant to this Agreement, the
Company shall use all reasonable efforts to timely file all reports required to
be filed with the SEC pursuant to the Exchange Act, and shall not terminate its
status as an issuer required to file reports under the Exchange Act even if the
Exchange Act or the rules and regulations thereunder would permit such
termination.

         d. Use of Proceeds. The Company shall use the net proceeds from the
sale of the Shares for general corporate purposes and working capital.

         e. Financial Information. The Company agrees to send to each Purchaser
within ten (10) days after the filing with the SEC, to the extent not available
through the SEC's EDGAR system, a copy of its Annual Report on Form 10-K, its
Quarterly Reports on Form 10-Q, its proxy and information statements and any
Current Reports on Form 8-K.

         f. Reservation of Shares. The Company has and shall at all times have
authorized and reserved for the purpose of issuance a sufficient number of
shares of Common Stock to provide for the full conversion of the Shares and the
issuance of the Common Stock in connection therewith and as otherwise required
hereby and pursuant to the terms of the Certificate of Designation. The Company
shall not reduce the number of shares of Common Stock reserved for issuance
under this

                                       12

<PAGE>

Agreement (except as a result of the issuance of the Common Stock upon the
exercise of the Shares), without the consent of the Purchasers.

         g. Listing. The Company will apply for the listing of the Common Stock
issuable upon conversion of the Shares upon each national securities exchange
and automated quotation system, if any, upon which shares of Common Stock are
then listed or quoted and shall maintain, so long as any other shares of Common
Stock shall be so listed, such listing of all Common Stock issuable upon
conversion of the Shares from time to time issuable hereunder.

         h. No Integrated Offerings; Registration.

                  (i) The Company shall not make any offers or sales of any
security (other than the Shares) under circumstances that would require
registration of the Shares being offered or sold hereunder under the Securities
Act or cause this offering of Shares to be integrated with any other non-exempt
offering of securities.

                  (ii) Within ninety (90) days from the date hereof, the Company
shall file a registration statement on Form S-3 (or, if Form S-3 is not then
available, on such form of registration statement as is then available) under
the Securities Act (the "REGISTRATION STATEMENT") covering (i) all of the Common
Stock issuable upon conversion of the Shares, and (ii) all other "Registrable
Securities" under the Convertible Loan Agreement, as defined in Section 5(l)
below, and the Company shall use its best efforts to cause the Registration
Statement to be declared effective and to keep the Registration Statement
continuously effective until all of the Registrable Securities cease to be
Registrable Securities.

                  (iii) The Registration Statement, to the extent allowable
under the Securities Act and the rules promulgated thereunder, shall state that
the Registration Statement also covers such indeterminate number of additional
shares of Common Stock as may become issuable upon exercise of the Shares to
prevent dilution resulting from stock splits, stock dividends or similar
transactions. The Company agrees, if necessary, to supplement or amend the
Registration Statement, as required by the registration form utilized by the
Company or by the instructions applicable to such registration form or by the
Securities Act, and the Company agrees to furnish to the holders of the Shares
copies of any such supplement or amendment prior to its being used.

                  (iv) The covenants of the Company described in this Section
5(h) may be assigned by any Purchaser to any Person to whom such Purchaser
assigns or transfers any Shares, subject to the requirements of Section 8(g)
hereof.

         i. Furnishing of Information. As long as any Purchaser owns Shares, or
Common Stock issuable upon conversion of the Shares, the Company covenants to
timely file (or obtain extensions in respect thereof and file within the
applicable grace period) all reports required to be filed by the Company after
the date hereof pursuant to the Exchange Act. Upon the request of any Purchaser,
the Company shall deliver to such Purchaser a written certification of a duly
authorized officer as to whether it has complied with the preceding sentence.
During the earlier of (i) the date two (2) years from the Closing Date or (ii)
as long as any Purchaser owns Shares, or Common Stock issuable upon conversion
of the Shares, if the Company is not required to file reports pursuant to such
laws, it will prepare and furnish to the Purchasers and make publicly available
in accordance with paragraph (c)

                                       13

<PAGE>

of Rule 144 such information as is required for the Purchasers to sell the
Shares, or Common Stock issuable upon conversion of the Shares, under Rule 144.
The Company further covenants that it will take such further action as any
holder of Shares, or Common Stock issuable upon conversion of the Shares, may
reasonably request to satisfy the provisions of Rule 144 applicable to the
issuer of securities relating to transactions for the sale of securities
pursuant to Rule 144.

         j. Integration. The Company shall not, and shall use its best efforts
to ensure that no Affiliate of the Company shall, sell, offer for sale or
solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that would be integrated with the
offer or sale of the Shares in a manner that would require the registration
under the Securities Act of the sale of the Shares to the Purchasers.

         k. Indemnification. If any Purchaser or any of its Affiliates or any
officer, director, partner, controlling Person, employee or agent of a Purchaser
or any of its Affiliates (a "RELATED PERSON") becomes involved in any capacity
in any Proceeding brought by or against any Person in connection with or as a
result of any misrepresentation, breach or inaccuracy of any representation,
warranty, covenant or agreement made by the Company in any Transaction
Documents, the Company will indemnify and hold harmless such Purchaser or
Related Person for its reasonable legal and other expenses (including the costs
of any investigation, preparation and travel) and for any losses incurred in
connection therewith, as such expenses or losses are incurred, excluding only
losses that result directly from such Purchaser's or Related Person's gross
negligence or willful misconduct. The indemnification obligations of the Company
under this paragraph shall be in addition to any liability that the Company may
otherwise have and shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Purchasers and
any Related Persons. The Company also agrees that neither the Purchasers nor any
Related Persons shall have any liability to the Company or any Person asserting
claims on behalf of or in right of the Company in connection with or as a result
of the transactions contemplated by the Transaction Documents, except to the
extent that any losses incurred by the Company result from the gross negligence
or willful misconduct of the applicable Purchaser or Related Person in
connection with such transactions. If the Company breaches its obligations under
any Transaction Document, then, in addition to any other liabilities the Company
may have under any Transaction Document or applicable law, the Company shall pay
or reimburse the Purchasers on demand for all costs of collection and
enforcement (including reasonable attorneys fees and expenses). Without limiting
the generality of the foregoing, the Company specifically agrees to reimburse
the Purchasers on demand for all costs of enforcing the indemnification
obligations in this paragraph.

language used herein and therein shall be deemed to be the language chosen by
the parties hereto to express their mutual intent, and no rule of strict
construction will be applied against any party to this Agreement.

         l. Determinations. All consents, approvals and other determinations to
be made by the Purchasers pursuant to this Agreement and all waivers and
amendments to or of any provisions in

                                       18
<PAGE>

this Agreement to be binding upon a Purchaser shall be made by Purchasers that
have invested more than fifty percent (50%) of the aggregate Investment Amounts
invested by all Purchasers hereunder.

         m. Fees and Expenses. At the Closing, the Company shall pay to RENN
Capital Group, Inc. its legal fees and expenses incurred in connection with the
preparation and negotiation of the Transaction Documents. In lieu of the
foregoing payment, RENN Capital Group, Inc. may retain such amount at the
Closing or require the Company to pay such amount directly to Kirkpatrick &
Lockhart LLP. Except as expressly set forth in the Transaction Documents to the
contrary, each party shall pay the fees and expenses of its advisers, counsel,
accountants and other experts, if any, and all other expenses incurred by such
party incident to the negotiation, preparation, execution, delivery and
performance of this Agreement. The Company shall pay all transfer agent fees,
stamp taxes and other taxes and duties levied in connection with the issuance of
the Shares.

         n. Replacement of Shares. If any certificate or instrument evidencing
any Shares, or upon conversion of the Shares, any Common Stock, is mutilated,
lost, stolen or destroyed, the Company shall issue or cause to be issued in
exchange and substitution for and upon cancellation thereof, or in lieu of and
substitution therefor, a new certificate or instrument, but only upon receipt of
evidence reasonably satisfactory to the Company of such loss, theft or
destruction and customary and reasonable indemnity, if requested. The applicants
for a new certificate or instrument under such circumstances shall also pay any
reasonable third-party costs associated with the issuance of such replacement
Shares, or upon conversion of the Shares, any Common Stock.

         o. Remedies. In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the
Purchasers and the Company will be entitled to specific performance under the
Transaction Documents. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of
obligations described in the foregoing sentence and hereby agree to waive in any
action for specific performance of any such obligation the defense that a remedy
at law would be adequate.

         p. Adjustments in Share Numbers and Prices. In the event of any stock
split, subdivision, dividend or distribution payable in shares of Common Stock
(or other securities or rights convertible into, or entitling the holder thereof
to receive directly or indirectly shares of Common Stock), combination or other
similar recapitalization or event occurring after the date hereof, each
reference in any Transaction Document to a number of shares or a price per share
shall be amended to appropriately account for such event.

         q. Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser under any Transaction Document are several and not
joint with the obligations of any other Purchaser, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser under any Transaction Document. The decision of each Purchaser to
purchase Shares pursuant to this Agreement has been made by such Purchaser
independently of any other Purchaser and independently of any information,
materials, statements or opinions as to the business, affairs, operations,
assets, properties, liabilities, results of operations, condition (financial or
otherwise) or prospects of the Company or of the Subsidiary which may have been
made or given by any other Purchaser or by any agent or employee of any other
Purchaser, and no Purchaser or any of its agents or employees shall have any
liability to any other Purchaser (or any other Person) relating to or arising
from any such information, materials, statements or opinions. Nothing

                                       19
<PAGE>

contained herein or in any Transaction Document, and no action taken by any
Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert or as
a group with respect to such obligations or the transactions contemplated by the
Transaction Document. Each Purchaser acknowledges that no other Purchaser has
acted as agent for such Purchaser in connection with making its investment
hereunder and that no other Purchaser will be acting as agent of such Purchaser
in connection with monitoring its investment hereunder. Each Purchaser shall be
entitled to independently protect and enforce its rights, including without
limitation the rights arising out of this Agreement or out of the other
Transaction Documents, and it shall not be necessary for any other Purchaser to
be joined as an additional party in any proceeding for such purpose.

Obligations and (ii) the Maximum Revolving Loan Limit minus the Letter of Credit
Obligations. If at any time the outstanding Revolving Loans exceeds either the
Revolving Loan Limit or the Maximum Revolving Loan Limit, in each case minus the
Letter of Credit Obligations, or any portion of the Revolving Loans and Letter
of Credit Obligations exceeds any applicable sublimit within the Revolving Loan
Limit, Borrowers shall immediately, and without the necessity of demand by
Lender, pay to Lender such amount as may be necessary to eliminate such excess
and Lender shall apply such payment to the Revolving Loans to eliminate such
excess.

         Each Borrower hereby authorizes Lender, in its sole discretion, to
charge any of such Borrower's accounts or advance Revolving Loans to make any
payments of principal, interest, fees, costs or expenses required to be made
under this Agreement or the Other Agreements.

         A request for a Revolving Loan shall be made or shall be deemed to be
made, each in the following manner: the Borrower requesting such Revolving Loan
shall give Lender same day notice, no later than 1:00 P.M. (determined based on
the local time of each Borrower at its principal place of business) for such
day, of its request for a Revolving Loan as a Prime Rate Loan. In the event that
a Borrower maintains a controlled disbursement account at LaSalle Bank, each
check presented for payment against such controlled disbursement account and any
other charge or request for payment against such controlled disbursement account
shall constitute a request for a Revolving Loan as a Prime Rate Loan. As an
accommodation to Borrowers, Lender may permit telephone requests for Revolving
Loans and electronic transmittal of instructions, authorizations, agreements or
reports to Lender by Borrowers. Unless a Borrower specifically directs Lender in
writing not to accept or act upon telephonic or electronic communications from
such Borrower, Lender shall have no liability to Borrowers for any loss or
damage suffered by a Borrower as a result of Lender's honoring of any requests,
execution of any instructions, authorizations or agreements or reliance on any
reports communicated to it telephonically or electronically and purporting to
have been sent to Lender by a Borrower and Lender shall have no duty to verify
the origin of any such communication or the authority of the Person sending it.

         Each Borrower hereby irrevocably authorizes Lender to disburse the
proceeds of each Revolving Loan requested by such Borrower, or deemed to be
requested by such Borrower, as follows: the proceeds of each Revolving Loan
requested under Section 2(a) shall be disbursed by Lender in lawful money of the
United States of America in immediately available funds, in the case of the
initial borrowing, in accordance with the terms of the written disbursement
letter from such Borrower, and in the case of each subsequent borrowing, by wire
transfer or Automated Clearing House (ACH) transfer to such bank account as may
be agreed upon by such Borrower and Lender from time to time, or elsewhere if
pursuant to a written direction from such Borrower.

         (b) CAPITAL EXPENDITURE LOANS.

         Subject to the terms and conditions of this Agreement and the Other
Agreements, from time to time after the initial Loans are advanced hereunder,
Lender shall make advances to each Borrower up to eighty percent (80%) of the
purchase price (exclusive of sales taxes, delivery charges and other "soft"
costs related to such purchase) of Equipment to be purchased with the proceeds
of such advances, which Equipment is acceptable to Lender in its sole
discretion, and upon which Lender shall have a first priority perfected security
interest; provided, that (i) the aggregate amount advanced for such purchases
shall not exceed Five Hundred Thousand and No/100 Dollars ($500,000.00), (ii) at
least three (3) Business Days prior to any such advance hereunder, such Borrower
shall have furnished to Lender an invoice and acceptance letter for the
Equipment being purchased and shall have executed such documents and taken such
other actions as Lender shall require to assure that Lender has a first priority
perfected security interest in such Equipment, and (iii) each advance hereunder
shall be in an amount not less than Fifty Thousand and No/100 Dollars
($50,000.00). Amounts repaid with respect to the Capital Expenditure Loans may
not be reborrowed.

         (c) REPAYMENTS.

         The Liabilities shall be repaid as follows:

                  (i) Repayment of Revolving Loans. The Revolving Loans and all
         other Liabilities (other than the Term Loan) shall be repaid on the
         last day of the Original Term or any Renewal Term if this Agreement is
         renewed pursuant to Section 10 hereof.

                  (ii) Repayment of Capital Expenditure Loans. Each Capital
         Expenditure Loan shall be repaid in forty-eight (48) equal monthly
         installments in an amount sufficient to repay such Capital Expenditure
         Loan in full by the final payment. Such payments shall be made on the
         thirtieth (30th) day following the date of each such advance, and on
         the corresponding day of each month thereafter; provided, that any
         remaining outstanding principal balance of the Capital Expenditures
         Loan shall be repaid at the end of the Original Term or any Renewal
         Term if this Agreement is renewed pursuant to Section 10 hereof. If any
         such payment due date is not a Business Day, then such payment may be
         made on the next succeeding Business Day and such extension of time
         shall be included in the computation of the amount of interest and fees
         due hereunder.

                  (iii) Mandatory Prepayments of the Term Loan.

                           (a) Sales of Assets. Upon receipt of the proceeds of
                  the sale or other disposition of any Equipment or real
                  property of a Borrower which is subject to a mortgage in favor
                  of Lender, or if any of the Equipment or real

                                      -12-
<PAGE>

                  property subject to such mortgage is damaged, destroyed or
                  taken by condemnation in whole or in part, the proceeds
                  thereof shall be paid by such Borrower to Lender as a
                  mandatory prepayment of the Capital Expenditure Loan which was
                  advanced against the value of such asset, such payment to be
                  applied against the remaining installments of principal in the
                  inverse order of their maturities until such Capital
                  Expenditure Loan is repaid in full, and then against the other
                  Liabilities, as determined by Lender, in its sole discretion.

         (d) NOTES.

         The Loans shall, in Lender's sole discretion, be evidenced by one or
more promissory notes in form and substance satisfactory to Lender. However, if
such Loans are not so evidenced, such Loans may be evidenced solely by entries
upon the books and records maintained by Lender.

         3. LETTERS OF CREDIT.

         (a) GENERAL TERMS.

         Subject to the terms and conditions of this Agreement and the Other
Agreements, during the Original Term or any Renewal Term, Lender may, in its
sole discretion, from time to time cause to be issued and co-sign for or
otherwise guarantee, upon a Borrower's request, commercial and/or standby
Letters of Credit; provided, that the aggregate undrawn face amount of all such
Letters of Credit shall at no time exceed Two Million and No/100 Dollars
($2,000,000.00). Payments made by the issuer of a Letter of Credit to any Person
on account of any Letter of Credit shall be immediately payable by Borrowers
without notice, presentment or demand and each Borrower agrees that each payment
made by the issuer of a Letter of Credit in respect of a Letter of Credit shall
constitute a request by each Borrower for a Loan to reimburse such issuer. In
the event such Loan is not advanced by Lender for any reason, such reimbursement
obligations (whether owing to the issuer of the Letter of Credit or Lender if
Lender is not the issuer) shall become part of the Liabilities hereunder and
shall bear interest at the rate then applicable to Revolving Loans constituting
Prime Rate Loans until repaid. Borrowers shall remit to Lender a Letter of
Credit fee equal to two and one-half percent (2-1/2%) per annum on the aggregate
undrawn face amount of all Letters of Credit outstanding, which fee shall be
payable monthly in arrears on the last Business Day of each month. Borrowers
shall also pay on demand the normal and customary administrative charges of the
issuer of the Letter of Credit for issuance, amendment, negotiation, renewal or
extension of any Letter of Credit.

         (b) REQUESTS FOR LETTERS OF CREDIT.

         Each Borrower shall make requests for Letters of Credit in writing at
least two (2) Business Days prior to the date such Letter of Credit is to be
issued. Each such request shall specify the date such Letter of Credit is to be
issued, the amount thereof, the name and

                                      -13-
<PAGE>

address of the beneficiary thereof and a description of the transaction to be
supported thereby. Any such notice shall be accompanied by the form of Letter of
Credit requested and any application or reimbursement agreement required by the
issuer of such Letter of Credit. If any term of such application or
reimbursement agreement is inconsistent with this Agreement, then the provisions
of this Agreement shall control to the extent of such inconsistency.

         (c) OBLIGATIONS ABSOLUTE.

         Each Borrower shall be obligated to reimburse the issuer of any Letter
of Credit, or Lender if Lender has reimbursed such issuer on a Borrower's
behalf, for any payments made in respect of any Letter of Credit, which
obligation shall be unconditional and irrevocable and shall be paid regardless
of: (i) any lack of validity or enforceability of any Letter of Credit, (ii) any
amendment or waiver of or consent or departure from all or any provisions of any
Letter of Credit, this Agreement or any Other Agreement, (iii) the existence of
any claim, set off, defense or other right which a Borrower or any other Person
may have against any beneficiary of any Letter of Credit, Lender or the issuer
of the Letter of Credit, (iv) any draft or other document presented under any
Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in
any respect or any statement therein being untrue or inaccurate in any respect,
(v) any payment under any Letter of Credit against presentation of a draft or
other document that does not comply with the terms of such Letter of Credit, and
(vi) any other act or omission to act or delay of any kind of the issuer of such
Letter of Credit, the Lender or any other Person or any other event or
circumstance that might otherwise constitute a legal or equitable discharge of a
Borrower's obligations hereunder. It is understood and agreed by each Borrower
that the issuer of any Letter of Credit may accept documents that appear on
their face to be in order without further investigation or inquiry, regardless
of any notice or information to the contrary.

         (d) EXPIRATION DATES OF LETTERS OF CREDIT.

         The expiration date of each Letter of Credit shall be no later than the
earlier of (i) one (1) year from the date of issuance and (ii) the thirtieth
(30th) day prior to the end of the Original Term or any Renewal Term.
Notwithstanding the foregoing, a Letter of Credit may provide for automatic
extensions of its expiration date for one or more one (1) year periods, so long
as the issuer thereof has the right to terminate the Letter of Credit at the end
of each one (1) year period and no extension period extends past the thirtieth
(30th) day prior to the end of the Original Term or any Renewal Term.

         4. INTEREST, FEES AND CHARGES.

         (a) INTEREST RATE.

         Each Loan shall bear interest at the rate of one percent (1%) per annum
in excess of the Prime Rate in effect from time to time, payable on the last
Business Day of each

                                      -14-
<PAGE>

month in arrears. Said rate of interest shall increase or decrease by an amount
equal to each increase or decrease in the Prime Rate effective on the effective
date of each such change in the Prime Rate. Upon the occurrence of an Event of
Default and during the continuance thereof, each Loan shall bear interest at the
rate of two percent (2%) per annum in excess of the interest rate otherwise
payable thereon, which interest shall be payable on demand. All interest shall
be calculated on the basis of a 360-day year.

         (b) FEES AND CHARGES.

                  (i) Closing Fee: Borrowers shall jointly and severally pay to
         Lender a closing fee of One Hundred Thousand and No/100 Dollars
         ($100,000.00), which fee shall be fully earned and payable on the date
         of disbursement of the initial Loans hereunder.

                  (ii) Unused Line Fee: Borrowers shall jointly and severally
         pay to Lender an unused line fee of one-half of one percent (1/2 of 1%)
         of the difference between the Maximum Revolving Loan Limit and the
         average daily balance of the Revolving Loans plus the Letter of Credit
         Obligations for each month, which fee shall be fully earned by Lender
         and payable monthly in arrears on the first Business Day of each month.
         Said fee shall be calculated on the basis of a 360 day year.

                  (iii) Transaction Fee: Borrowers shall jointly and severally
         pay to Lender a transaction fee of Twenty Thousand and No/100 Dollars
         ($20,000.00) with respect to internal costs and expenses (in addition
         to any reimbursable out-of-pocket costs and expenses of Lender) related
         to the closing of the loan transaction contemplated hereby, which fee
         shall be fully earned and payable on the date that Lender makes its
         initial disbursement of Loans hereunder.

                  (iv) Costs and Expenses: Borrowers shall jointly and severally
         reimburse Lender for all costs and expenses, including, without
         limitation, legal expenses and reasonable attorneys' fees (whether for
         internal or outside counsel), incurred by Lender in connection with the
         (i) documentation and consummation of this transaction and any other
         transactions between Borrowers and Lender, including, without
         limitation, Uniform Commercial Code and other public record searches
         and filings, overnight courier or other express or messenger delivery,
         appraisal costs, surveys, title insurance and environmental audit or
         review costs; (ii) collection, protection or enforcement of any rights
         in or to the Collateral; (iii) collection of any Liabilities; and (iv)
         administration and enforcement of any of Lender's rights under this
         Agreement or any Other Agreement. Borrowers shall also pay all normal
         service charges with respect to all accounts maintained by each
         Borrower with Lender and LaSalle Bank and any additional services
         requested by a Borrower from Lender and LaSalle Bank. All such costs,
         expenses and charges shall, if owed to LaSalle Bank, be reimbursed by
         Lender and in such event or in the event such costs and expenses are
         owed to Lender, shall constitute Liabilities hereunder, shall be
         payable by Borrowers

                                      -15-
<PAGE>

         to Lender on demand, and, until paid, shall bear interest at the
         highest rate then applicable to Loans hereunder.

                  (v) Capital Adequacy Charge. If Lender shall have determined
         that the adoption of any law, rule or regulation regarding capital
         adequacy, or any change therein or in the interpretation or application
         thereof, or compliance by Lender with any request or directive
         regarding capital adequacy (whether or not having the force of law)
         from any central bank or governmental authority enacted after the date
         hereof, does or shall have the effect of reducing the rate of return on
         such party's capital as a consequence of its obligations hereunder to a
         level below that which Lender could have achieved but for such
         adoption, change or compliance (taking into consideration Lender's
         policies with respect to capital adequacy) by a material amount, then
         from time to time, after submission by Lender to Borrowers of a written
         demand therefor ("CAPITAL ADEQUACY DEMAND") together with the
         certificate described below, Borrowers shall pay to Lender such
         additional amount or amounts ("CAPITAL ADEQUACY CHARGE") as will
         compensate Lender for such reduction, such Capital Adequacy Demand to
         be made with reasonable promptness following such determination. A
         certificate of Lender claiming entitlement to payment as set forth
         above shall be conclusive in the absence of manifest error. Such
         certificate shall set forth the nature of the occurrence giving rise to
         such reduction, the amount of the Capital Adequacy Charge to be paid to
         Lender, and the method by which such amount was determined. In
         determining such amount, Lender may use any reasonable averaging and
         attribution method, applied on a non-discriminatory basis.

         (c) MAXIMUM INTEREST.

         It is the intent of the parties that the rate of interest and other
charges to each Borrower under this Agreement and the Other Agreements shall be
lawful; therefore, if for any reason the interest or other charges payable under
this Agreement are found by a court of competent jurisdiction, in a final
determination, to exceed the limit which Lender may lawfully charge such
Borrower, then the obligation to pay interest and other charges shall
automatically be reduced to such limit and, if any amount in excess of such
limit shall have been paid, then such amount shall be refunded to such Borrower.

         5. COLLATERAL.

         (a) GRANT OF SECURITY INTEREST TO LENDER.

         As security for the payment of all Loans now or in the future made by
Lender to Borrowers hereunder and for the payment or other satisfaction of all
other Liabilities, each Borrower hereby assigns to Lender and grants to Lender a
continuing security interest in the following property of such Borrower, whether
now or hereafter owned, existing, acquired or arising and wherever now or
hereafter located: (a) all Accounts (whether or not Eligible Accounts) and all
Goods whose sale, lease or other disposition by such Borrower has given

                                      -16-
<PAGE>

rise to Accounts and have been returned to, or repossessed or stopped in transit
by, such Borrower; (b) all Chattel Paper, Instruments, Documents and General
Intangibles (including, without limitation, all patents, patent applications,
trademarks, trademark applications, trade names, trade secrets, goodwill,
copyrights, copyright applications, registrations, licenses, software,
franchises, customer lists, tax refund claims, claims against carriers and
shippers, guarantee claims, contract rights, payment intangibles, security
interests, security deposits and rights to indemnification); (c) all Inventory
(whether or not Eligible Inventory); (d) all Goods (other than Inventory),
including, without limitation, Equipment, vehicles and Fixtures; (e) all
Investment Property; (f) all Deposit Accounts, bank accounts, deposits and cash;
(g) all Letter-of-Credit Rights; (h) Commercial Tort Claims listed on Exhibit C
hereto, (i) any other property of such Borrower now or hereafter in the
possession, custody or control of Lender or any agent or any parent, affiliate
or subsidiary of Lender or any participant with Lender in the Loans, for any
purpose (whether for safekeeping, deposit, collection, custody, pledge,
transmission or otherwise) and (j) all additions and accessions to,
substitutions for, and replacements, products and Proceeds of the foregoing
property, including, without limitation, proceeds of all insurance policies
insuring the foregoing property, and all of such Borrower's books and records
relating to any of the foregoing and to such Borrower's business.

         (b) OTHER SECURITY.

         Lender, in its sole discretion, without waiving or releasing any
obligation, liability or duty of a Borrower under this Agreement or the Other
Agreements or any Event of Default, may at any time or times hereafter, but
shall not be obligated to, pay, acquire or accept an assignment of any security
interest, lien, encumbrance or claim asserted by any Person in, upon or against
the Collateral, provided, that Lender may take such actions with respect to
Permitted Liens only after the occurrence and during the continuance of an Event
of Default. All sums paid by Lender in respect thereof and all costs, fees and
expenses including, without limitation, reasonable attorney fees, all court
costs and all other charges relating thereto incurred by Lender shall constitute
Liabilities, payable by Borrowers to Lender on demand and, until paid, shall
bear interest at the highest rate then applicable to Loans hereunder.

         (c) POSSESSORY COLLATERAL.

         Immediately upon a Borrower's receipt of any portion of the Collateral
evidenced by an agreement, Instrument or Document, including, without
limitation, any Tangible Chattel Paper and any Investment Property consisting of
certificated securities, such Borrower shall deliver the original thereof to
Lender together with an appropriate endorsement or other specific evidence of
assignment thereof to Lender (in form and substance acceptable to Lender). If an
endorsement or assignment of any such items shall not be made for any reason,
Lender is hereby irrevocably authorized, as each Borrower's attorney and
agent-in-fact, to endorse or assign the same on such Borrower's behalf.

                                      -17-
<PAGE>

         (d) ELECTRONIC CHATTEL PAPER.

         To the extent that a Borrower obtains or maintains any Electronic
Chattel Paper, such Borrower shall create, store and assign the record or
records comprising the Electronic Chattel Paper in such a manner that (i) a
single authoritative copy of the record or records exists which is unique,
identifiable and except as otherwise provided in clauses (iv), (v) and (vi)
below, unalterable, (ii) the authoritative copy identifies Lender as the
assignee of the record or records, (iii) the authoritative copy is communicated
to and maintained by the Lender or its designated custodian, (iv) copies or
revisions that add or change an identified assignee of the authoritative copy
can only be made with the participation of Lender, (v) each copy of the
authoritative copy and any copy of a copy is readily identifiable as a copy that
is not the authoritative copy and (vi) any revision of the authoritative copy is
readily identifiable as an authorized or unauthorized revision.

         6. PRESERVATION OF COLLATERAL AND PERFECTION OF SECURITY INTERESTS
THEREIN.

         Each Borrower shall, at Lender's request, at any time and from time to
time, authenticate, execute and deliver to Lender such financing statements,
documents and other agreements and instruments (and pay the cost of filing or
recording the same in all public offices deemed necessary or desirable by
Lender) and do such other acts and things or cause third parties to do such
other acts and things as Lender may deem necessary or desirable in its sole
discretion in order to establish and maintain a valid, attached and perfected
security interest in the Collateral in favor of Lender (free and clear of all
other liens, claims, encumbrances and rights of third parties whatsoever,
whether voluntarily or involuntarily created, except Permitted Liens) to secure
payment of the Liabilities, and in order to facilitate the collection of the
Collateral. Each Borrower irrevocably hereby makes, constitutes and appoints
Lender (and all Persons designated by Lender for that purpose) as such
Borrower's true and lawful attorney and agent-in-fact to execute and file such
financing statements, documents and other agreements and instruments and do such
other acts and things as may be necessary to preserve and perfect Lender's
security interest in the Collateral. Each Borrower further agrees that a carbon,
photographic, photostatic or other reproduction of this Agreement or of a
financing statement shall be sufficient as a financing statement. Each Borrower
further ratifies and confirms the prior filing by Lender of any and all
financing statements which identify such Borrower as debtor, Lender as secured
party and any or all Collateral as collateral.

         7. POSSESSION OF COLLATERAL AND RELATED MATTERS.

         Until otherwise notified by Lender following the occurrence of an Event
of Default, each Borrower shall have the right, except as otherwise provided in
this Agreement, in the ordinary course of such Borrower's business, to (a) sell,
lease or furnish under contracts of service any of such Borrower's Inventory
normally held by such Borrower for any such purpose; (b) use and consume any raw
materials, work in process or other materials normally

                                      -18-
<PAGE>

held by such Borrower for such purpose; and (c) dispose of obsolete or unuseful
Equipment so long as all of the proceeds thereof are paid to Lender for
application to the Liabilities (except for such proceeds which are required to
be delivered to the holder of a Permitted Lien which is prior in right of
payment); provided, however, that a sale in the ordinary course of business
shall not include any transfer or sale in satisfaction, partial or complete, of
a debt owed by such Borrower.

         8. COLLECTIONS.

         (a) Each Borrower shall direct all of its Account Debtors to make all
payments on the Accounts directly to a post office box (the "LOCK BOX")
designated by, and under the exclusive control of, Lender, at a financial
institution acceptable to Lender. Each Borrower shall establish an account (the
"LOCK BOX ACCOUNT") in Lender's name with a financial institution acceptable to
Lender, into which all payments received in the Lock Box shall be deposited, and
into which such Borrower will immediately deposit all payments received by such
Borrower on Accounts in the identical form in which such payments were received,
whether by cash or check. If a Borrower, any Affiliate or Subsidiary, any
shareholder, officer, director, employee or agent of a Borrower or any Affiliate
or Subsidiary, or any other Person acting for or in concert with a Borrower
shall receive any monies, checks, notes, drafts or other payments relating to or
as Proceeds of Accounts or other Collateral, such Borrower and each such Person
shall receive all such items in trust for, and as the sole and exclusive
property of, Lender and, immediately upon receipt thereof, shall remit the same
(or cause the same to be remitted) in kind to the Lock Box Account. The
financial institution with which the Lock Box Account is established shall
acknowledge and agree, in a manner satisfactory to Lender, that the amounts on
deposit in such Lock Box and Lock Box Account are the sole and exclusive
property of Lender, that such financial institution will follow the instructions
of Lender with respect to disposition of funds in the Lock Box and Lock Box
Account without further consent from Borrowers, that such financial institution
has no right to setoff against the Lock Box or Lock Box Account or against any
other account maintained by such financial institution into which the contents
of the Lock Box or Lock Box Account are transferred, and that such financial
institution shall wire, or otherwise transfer in immediately available funds to
Lender in a manner satisfactory to Lender, funds deposited in the Lock Box
Account on a daily basis as such funds are collected. Each Borrower agrees that
all payments made to such Lock Box Account or otherwise received by Lender,
whether in respect of the Accounts or as Proceeds of other Collateral or
otherwise (except for proceeds of Collateral which are required to be delivered
to the holder of a Permitted Lien which is prior in right of payment), will be
applied on account of the Liabilities in accordance with the terms of this
Agreement. Each Borrower agrees to pay all customary fees, costs and expenses in
connection with opening and maintaining the Lock Box and Lock Box Account. All
of such fees, costs and expenses if not paid by a Borrower, may be paid by
Lender and in such event all amounts paid by Lender shall constitute Liabilities
hereunder, shall be payable to Lender by Borrowers upon demand, and, until paid,
shall bear interest at the highest rate then applicable to Loans hereunder. All
checks, drafts, instruments and other items of

                                      -19-
<PAGE>

payment or Proceeds of Collateral shall be endorsed by the applicable Borrower
to Lender, and, if that endorsement of any such item shall not be made for any
reason, Lender is hereby irrevocably authorized to endorse the same on such
Borrower's behalf. For the purpose of this section, each Borrower irrevocably
hereby makes, constitutes and appoints Lender (and all Persons designated by

         expected to have a Material Adverse Effect on such Borrower.

                           (vii) Default; Material Adverse Change. Promptly
         advise Lender of any material adverse change in the business, property,
         assets, prospects, operations or condition, financial or otherwise, of
         such Borrower, the occurrence of any Event of Default hereunder or the
         occurrence of any event which, if uncured, will become an Event of
         Default after notice or lapse of time (or both).

All of the foregoing notices shall be provided by Borrowers to Lender in
writing.

                  (c) COMPLIANCE WITH LAWS AND MAINTENANCE OF PERMITS.

                  Each Borrower shall maintain all governmental consents,
franchises, certificates, licenses, authorizations, approvals and permits, the
lack of which would have a Material Adverse Effect on such Borrower and each
Borrower shall remain in compliance with all applicable federal, state, local
and foreign statutes, orders, regulations, rules and ordinances (including,
without limitation, Environmental Laws and statutes, orders, regulations, rules
and ordinances relating to taxes, employer and employee contributions and
similar items, securities, ERISA or employee health and safety) the failure with
which to comply would have a Material Adverse Effect on such Borrower. Following
any determination by Lender that there is non-compliance, or any condition which
requires any action by or on behalf of a Borrower in order to avoid
non-compliance, with any Environmental Law, at such Borrower's expense cause an
independent environmental engineer acceptable to Lender to conduct such tests of
the relevant site(s) as are appropriate and prepare and deliver a report setting
forth the results of such tests, a proposed plan for remediation and an estimate
of the costs thereof.

                  (d) INSPECTION AND AUDITS.

                  Each Borrower shall permit Lender, or any Persons designated
by it, to call at such Borrower's places of business at any reasonable times,
and, without hindrance or delay, to inspect the Collateral and to inspect,
audit, check and make extracts from such Borrower's books, records, journals,
orders, receipts and any correspondence and other data relating to such
Borrower's business, the Collateral or any transactions between the parties
hereto, and shall have the right to make such verification concerning such
Borrower's business as Lender may consider reasonable under the circumstances.
Each Borrower shall furnish to Lender such information relevant to Lender's
rights under this Agreement and the Other Agreements as Lender shall at any time
and from time to time request. Lender, through its officers, employees or agents
shall have the right, at any time and from time to time, in Lender's name, to
verify the validity, amount or any other matter relating to any of such
Borrower's Accounts, by mail, telephone, telecopy, electronic mail, or
otherwise, provided that prior to the occurrence of an Event of Default, Lender
shall conduct such verification in the name of a nominee of Lender or in such
Borrower's name. Each Borrower authorizes Lender to discuss the affairs,
finances and business of such Borrower with any officers, employees or directors
of such Borrower or with its Parent or any Affiliate or the officers, employees
or directors of its Parent or any Affiliate, and to discuss the financial
condition of such Borrower with such Borrower's independent public accountants.
Any such discussions shall be without liability to Lender or to Borrowers'
independent public accountants. Borrowers shall pay to Lender all customary fees
and all costs and out-of-pocket expenses incurred by Lender in the exercise of
its rights hereunder, and all of such fees, costs and expenses shall constitute
Liabilities hereunder, shall be payable on demand and, until paid, shall bear
interest at the highest rate then applicable to Loans hereunder.

                  (e) INSURANCE.

                  Each Borrower shall:

                           (i) Keep the Collateral properly housed and insured
         for the full insurable value thereof against loss or damage by fire,
         theft, explosion, sprinklers, collision (in the case of motor vehicles)
         and such other risks as are customarily insured against by Persons
         engaged in businesses similar to that of such Borrower, with such
         companies, in such amounts, with such deductibles, and under policies
         in such form, as shall be satisfactory to Lender. Original (or
         certified) copies of such policies of insurance have been or shall be,
         within ninety (90) days of the date hereof, delivered to Lender,
         together with evidence of payment of all premiums therefor, and shall
         contain an endorsement, in form and substance acceptable to Lender,
         showing loss under such insurance policies payable to Lender. Such
         endorsement, or an independent instrument furnished to Lender, shall
         provide that the insurance company shall give Lender at least thirty
         (30) days written notice before any such policy of insurance is altered
         or canceled and that no act, whether willful or negligent, or default
         of such Borrower or any other Person shall affect the right of Lender
         to

                                      -31-
<PAGE>

         recover under such policy of insurance in case of loss or damage. In
         addition, each Borrower shall cause to be executed and delivered to
         Lender an assignment of proceeds of its business interruption insurance
         policies. Each Borrower hereby directs all insurers under all policies
         of insurance to pay all proceeds payable thereunder directly to Lender.
         Each Borrower irrevocably makes, constitutes and appoints Lender (and
         all officers, employees or agents designated by Lender) as such
         Borrower's true and lawful attorney (and agent-in-fact) for the purpose
         of making, settling and adjusting claims under such policies of
         insurance, endorsing the name of such Borrower on any check, draft,
         instrument or other item of payment for the proceeds of such policies
         of insurance and making all determinations and decisions with respect
         to such policies of insurance, provided however, that if no Event of
         Default shall have occurred and is continuing, Borrowers may make,
         settle and adjust claims involving less than $500,000.00 in the
         aggregate without Lender's consent.

                           (ii) Maintain, at its expense, such public liability
         and third party property damage insurance as is customary for Persons
         engaged in businesses similar to that of such Borrower with such
         companies and in such amounts, with such deductibles and under policies
         in such form as shall be satisfactory to Lender and original (or
         certified) copies of such policies have been or shall be, within ninety
         (90) days after the date hereof, delivered to Lender, together with
         evidence of payment of all premiums therefor; each such policy shall
         contain an endorsement showing Lender as additional insured thereunder
         and providing that the insurance company shall give Lender at least
         thirty (30) days written notice before any such policy shall be altered
         or canceled.

If a Borrower at any time or times hereafter shall fail to obtain or maintain
any of the policies of insurance required above or to pay any premium relating
thereto, then Lender, without waiving or releasing any obligation or default by
Borrowers hereunder, may (but shall be under no obligation to) obtain and
maintain such policies of insurance and pay such premiums and take such other
actions with respect thereto as Lender deems advisable upon notice to such
Borrower. Such insurance, if obtained by Lender, may, but need not, protect such
Borrower's interests or pay any claim made by or against such Borrower with
respect to the Collateral. Such insurance may be more expensive than the cost of
insurance such Borrower may be able to obtain on its own and may be cancelled
only upon such Borrower providing evidence that it has obtained the insurance as
required above. All sums disbursed by Lender in connection with any such
actions, including, without limitation, court costs, expenses, other charges
relating thereto and reasonable attorneys' fees, shall constitute Loans
hereunder, shall be payable on demand by Borrowers to Lender and, until paid,
shall bear interest at the highest rate then applicable to Loans hereunder.

                  (f) COLLATERAL.

                  Each Borrower shall keep the Collateral in good condition,
repair and order and shall make all necessary repairs to the Equipment and
replacements thereof so that the

                                      -32-
<PAGE>

operating efficiency and the value thereof shall at all times be preserved and
maintained in all material respects. Each Borrower shall permit Lender to
examine any of the Collateral at any time and wherever the Collateral may be
located and, each Borrower shall, immediately upon request therefor by Lender,
deliver to Lender any and all evidence of ownership of any of the Equipment
including, without limitation, certificates of title and applications of title.
Each Borrower shall, at the request of Lender, indicate on its records
concerning the Collateral a notation, in form satisfactory to Lender, of the
security interest of Lender hereunder.

                  (g) USE OF PROCEEDS.

                  All monies and other property obtained by a Borrower from
Lender pursuant to this Agreement shall be used solely for business purposes of
such Borrower.

                  (h) TAXES.

                  Each Borrower shall file all required tax returns and pay all
of its taxes when due, subject to any extensions granted by the applicable
taxing authority, including, without limitation, taxes imposed by federal, state
or municipal agencies, and shall cause any liens for taxes to be promptly
released; provided, that such Borrower shall have the right to contest the
payment of such taxes in good faith by appropriate proceedings so long as (i)
the amount so contested is shown on such Borrower's financial statements; (ii)
the contesting of any such payment does not give rise to a lien for taxes; (iii)
such Borrower keeps on deposit with Lender (such deposit to be held without
interest) or a reserve is maintained against such Borrower's availability to
borrow money under subsection 2(a), in either case, in an amount of money which,
in the sole judgment of Lender, is sufficient to pay such taxes and any interest
or penalties that may accrue thereon; and (iv) if such Borrower fails to
prosecute such contest with reasonable diligence, Lender may apply the money so
deposited in payment of such taxes. If a Borrower fails to pay any such taxes
and in the absence of any such contest by such Borrower, Lender may (but shall
be under no obligation to) advance and pay any sums required to pay any such
taxes and/or to secure the release of any lien therefor, and any sums so
advanced by Lender shall constitute Loans hereunder, shall be payable by such
Borrower to Lender on demand, and, until paid, shall bear interest at the
highest rate then applicable to Loans hereunder.

                  (i) INTELLECTUAL PROPERTY.

                  Each Borrower shall maintain adequate licenses, patents,
patent applications, copyrights, service marks, trademarks, trademark
applications, tradestyles and trade names to continue its business as heretofore
conducted by it or as hereafter conducted by it unless the failure to maintain
any of the foregoing could not reasonably be expected to have a Material Adverse
Effect on such Borrower.

                  (j) CHECKING ACCOUNTS.

Each Borrower shall maintain all of its demand deposit accounts, including its
controlled disbursement account, with LaSalle Bank; provided that each Borrower
may maintain payroll accounts and petty cash accounts at other financial
institutions so long as the aggregate amount of funds contained in all such
petty cash accounts shall not exceed $100,000.00 at any time. Normal charges
shall be assessed thereon.

                  13. NEGATIVE COVENANTS.

                  Until payment and satisfaction in full of all Liabilities and
termination of this Agreement, unless Borrowers obtain Lender's prior written

specific instance, each Borrower agrees as follows:

                  (a) GUARANTIES.

                  No Borrower shall assume, guarantee or endorse, or otherwise

                  (b) INDEBTEDNESS.

                  No Borrower shall create, incur, assume or become obligated
(directly or indirectly), for any loans or other indebtedness for borrowed money
other than the Loans, except that a Borrower may (i) borrow money from a Person
other than Lender on an unsecured and subordinated basis if a subordination
agreement in favor of Lender and in form and substance satisfactory to Lender is
executed and delivered to Lender relative thereto; (ii) maintain its present
indebtedness listed on Schedule 11(n) hereto; (iii) incur unsecured indebtedness
to trade creditors in the ordinary course of business; (iv) incur purchase money

Year of Borrowers.

                  (c) LIENS.

                  No Borrower shall grant or permit to exist (voluntarily or
involuntarily) any lien, claim, security interest or other encumbrance
whatsoever on any of its assets, other than Permitted Liens.

without limitation, any purchase, redemption or retirement of any shares of any
class of its stock or any other equity interest, and any issuance of any shares
of, or warrants or other rights to receive or purchase any shares of, any class
of its stock or any other equity interest, provided that Digital may issue stock
in accordance with the terms of its 2003 Stock Option Plan in effect as of the
date hereof; provided further that Digital may issue shares, warrants or other
rights to receive or purchase any shares of any class of its stock or any other
equity interest so long as no Event of Default would occur as a result thereof.
No Borrower shall form any Subsidiaries or enter into any joint ventures or
partnerships with any other Person.

                  (e) DIVIDENDS AND DISTRIBUTIONS.

(whether in cash or in kind) on any class of its stock (if such Borrower is a
corporation) or on account of any equity interest in such Borrower (if such
Borrower is a partnership, limited liability company or other type of entity).
Notwithstanding the foregoing and provided that (i) each such dividend payment
is permitted under all applicable laws; and (ii) no Event of Default shall have

                  No Borrower shall amend its organizational documents or change
its Fiscal Year or enter into a new line of business materially different from
such Borrower's current business unless (i) such actions would not have a
Material Adverse Effect on such Borrower; (ii) such actions would not affect the
obligations of such Borrower to Lender; (iii) such

                                      -35-

                  (n) CHANGE OF MANAGEMENT.

                  If David Turney shall cease to be the Chairman and President
of Digital or Executive Vice President of Digital Audio and TwinVision at any
time.

                  (o) MATERIAL ADVERSE CHANGE.

                  Any material adverse change in the Collateral, business,
property, assets, prospects, operations or condition, financial or otherwise of
any Obligor, as determined by Lender in its sole judgment or the occurrence of
any event which, in Lender's sole judgment, could have a Material Adverse
Effect.

                  16. REMEDIES UPON AN EVENT OF DEFAULT.

                  (a) Upon the occurrence and during the continuance of an Event
of Default described in subsection 15(g) hereof, all of the Liabilities shall
immediately and automatically become due and payable, without notice of any
kind. Upon the occurrence of any other Event of Default, all Liabilities may, at
the option of Lender, and without demand, notice or legal process of any kind,
be declared, and immediately shall become, due and payable.

                  (b) Upon the occurrence and during the continuance of an Event
of Default, Lender may exercise from time to time any rights and remedies
available to it under the Uniform Commercial Code and any other applicable law
in addition to, and not in lieu of, any rights and remedies expressly granted in
this Agreement or in any of the Other Agreements and all of Lender's rights and
remedies shall be cumulative and non-exclusive to the extent permitted by law.
In particular, but not by way of limitation of the foregoing, Lender may,
without notice, demand or legal process of any kind, take possession of any or
all of the Collateral (in addition to Collateral of which it already has
possession), wherever it may be found, and for that purpose may pursue the same
wherever it may be found, and may enter onto any of Borrowers' premises where
any of the Collateral may be, and search for, take possession of, remove, keep
and store any of the Collateral until the same shall be sold or otherwise
disposed of, and Lender shall have the right to store the same at any of
Borrowers' premises without cost to Lender. At Lender's request, each Borrower
shall, at Borrowers' expense, assemble the Collateral and make it available to
Lender at one or more places to be designated by Lender and reasonably
convenient to Lender and such Borrower. Each Borrower recognizes that if a
Borrower fails to perform, observe or discharge any of its Liabilities under
this Agreement or the Other Agreements, no remedy at law will provide adequate
relief to Lender, and agrees that Lender shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
actual damages. Any notification of intended disposition of any of the
Collateral required by law will be deemed to be a reasonable authenticated
notification of disposition if given at least ten (10) days prior to such
disposition and such notice shall (i) describe Lender and the applicable
Borrower(s), (ii) describe the Collateral that is the subject to the intended
disposition, (iii)

                                      -40-
<PAGE>

state the method of the intended disposition, (iv) state that the applicable
Borrower(s) is entitled to an accounting of the Liabilities and state the
charge, if any, for an accounting and (v) state the time and place of any public
disposition or the time after which any private sale is to be made. Lender may
disclaim any warranties that might arise in connection with the sale, lease or
other disposition of the Collateral and has no obligation to provide any
warranties at such time. Any Proceeds of any disposition by Lender of any of the
Collateral may be applied by Lender to the payment of expenses in connection
with the Collateral, including, without limitation, legal expenses and
reasonable attorneys' fees, and any balance of such Proceeds may be applied by
Lender toward the payment of such of the Liabilities, and in such order of
application, as Lender may from time to time elect.

                  17. CONDITIONS PRECEDENT.

                  The obligation of Lender to fund the Term Loan, to fund the
initial Revolving Loan, and to issue or cause to be issued the initial Letter of
Credit, is subject to the satisfaction or waiver on or before the date hereof of
the following conditions precedent:

                  (a) Lender shall have received each of the agreements,
opinions, reports, approvals, consents, certificates and other documents set
forth on the closing document list attached hereto as Schedule 17(a) (the
"CLOSING DOCUMENT LIST") in each case in form and substance satisfactory to
Lender;

                  (b) Since September 30, 2003, no event shall have occurred
which has had or could reasonably be expected to have a Material Adverse Effect
on any Obligor, as determined by Lender in its sole discretion, determined in
good faith;

                  (c) Lender shall have received payment in full of all fees and
expenses payable to it by Borrowers or any other Person in connection herewith,
on or before disbursement of the initial Loans hereunder;

                  (d) Lender shall have determined that immediately after giving
effect to (A) the making of the initial Loans, including without limitation the
Term Loan and the Revolving Loans, if any, requested to be made on the date
hereof, (B) the issuance of the initial Letter of Credit, if any, requested to
be made on such date, (C) the payment of all fees due upon such date and (D) the
payment or reimbursement by Borrowers of Lender for all closing costs and
expenses incurred in connection with the transactions contemplated hereby,
Borrowers have Excess Availability of not less than Five Hundred Thousand and
No/100 Dollars ($500,000.00);

                  (e) The Obligors shall have executed and delivered to Lender
all such other documents, instruments and agreements which Lender determines are
reasonably necessary to consummate the transactions contemplated hereby,
including, without limitation, a secured Continuing Unconditional Guaranty of
Robinson Turney International, Inc.; and

                                      -41-
<PAGE>

                  (f) Renaissance US Growth and Income Trust PLC, Renaissance
Capital Group, Inc., John D. Higgins and Begnt Bodin shall each execute and
deliver a Subordination Agreement in form and substance satisfactory to Lender.
In addition, the maturity dates with respect to all such indebtedness shall be
extended to a date subsequent to the Original Term.

                  18. JOINT AND SEVERAL LIABILITY.

                  (a) Notwithstanding anything to the contrary contained herein,
all Liabilities of each Borrower hereunder shall be joint and several
obligations of Borrowers.

                  (b) Notwithstanding any provisions of this Agreement to the
contrary, it is intended that the joint and several nature of the Liabilities of
Borrowers and the liens and security interests granted by Borrowers to secure
the Liabilities, not constitute a "Fraudulent Conveyance" (as defined below).
Consequently, Lender and Borrowers agree that if the Liabilities of a Borrower,
or any liens or security interests granted by such Borrower securing the
Liabilities would, but for the application of this sentence, constitute a
Fraudulent Conveyance, the Liabilities of such Borrower and the liens and
security interests securing such Liabilities shall be valid and enforceable only
to the maximum extent that would not cause such Liabilities or such lien or
security interest to constitute a Fraudulent Conveyance, and the Liabilities of
such Borrower and this Agreement shall automatically be deemed to have been
amended accordingly. For purposes hereof, "Fraudulent Conveyance" means a
fraudulent conveyance under Section 548 of Chapter 11 of Title II of the United
States Code (11 U.S.C. Section 101, et seq.), as amended (the "Bankruptcy Code")
or a fraudulent conveyance or fraudulent transfer under the applicable
provisions of any fraudulent conveyance or fraudulent transfer law or similar
law of any state, nation or other governmental unit, as in effect from time to
time.

                  (c) Each Borrower assumes responsibility for keeping itself
informed of the financial condition of each other Borrower, and any and all
endorsers and/or guarantors of any instrument or document evidencing all or any
part of such other Borrower's Liabilities and of all other circumstances bearing
upon the risk of nonpayment by such other Borrowers of their Liabilities and
each Borrower agrees that Lender shall not have any duty to advise such Borrower
of information known to Lender regarding such condition or any such
circumstances or to undertake any investigation not a part of its regular
business routine. If Lender, in its sole discretion, undertakes at any time or
from time to time to provide any such information to a Borrower, Lender shall
not be under any obligation to update any such information or to provide any
such information to such Borrower on any subsequent occasion.

                  (d) Lender is hereby authorized, without notice or demand and
without affecting the liability of a Borrower hereunder, to, at any time and
from time to time, (i) renew, extend, accelerate or otherwise change the time
for payment of, or other terms relating to a Borrower's Liabilities or otherwise
modify, amend or change the terms of any promissory note or other agreement,
document or instrument now or hereafter executed by a

                                      -42-
<PAGE>

Borrower and delivered to Lender; (ii) accept partial payments on a Borrower's
Liabilities; (iii) take and hold security or collateral for the payment of a
Borrower's Liabilities hereunder or for the payment of any guaranties of a
Borrower's Liabilities or other liabilities of a Borrower and exchange, enforce,
waive and release any such security or collateral; (iv) apply such security or
collateral and direct the order or manner of sale thereof as Lender, in its sole
discretion, may determine; and (v) settle, release, compromise, collect or
otherwise liquidate a Borrower's Liabilities and any security or collateral
therefor in any manner, without affecting or impairing the obligations of the
other Borrowers. Lender shall have the exclusive right to determine the time and
manner of application of any payments or credits, whether received from a
Borrower or any other source, and such determination shall be binding on such
Borrower. All such payments and credits may be applied, reversed and reapplied,
in whole or in part, to any of a Borrower's Liabilities as Lender shall
determine in its sole discretion without affecting the validity or
enforceability of the Liabilities of the other Borrowers.

                  (e) Each Borrower hereby agrees that, except as hereinafter
provided, its obligations hereunder shall be unconditional, irrespective of (i)
the absence of any attempt to collect a Borrower's Liabilities from any Borrower
or any guarantor or other action to enforce the same; (ii) the waiver or consent
by Lender with respect to any provision of any instrument evidencing Borrowers'
Liabilities, or any part thereof, or any other agreement heretofore, now or
hereafter executed by a Borrower and delivered to Lender; (iii) failure by
Lender to take any steps to perfect and maintain its security interest in, or to
preserve its rights to, any security or collateral for Borrowers' Liabilities;
(iv) the institution of any proceeding under the Bankruptcy Code, or any similar
proceeding, by or against a Borrower or Lender's election in any such proceeding
of the application of Section 1111(b)(2) of the Bankruptcy Code; (v) any
borrowing or grant of a security interest by any Borrower as
debtor-in-possession, under Section 364 of the Bankruptcy Code; (vi) the
disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of
Lender's claim(s) for repayment of any of Borrowers' Liabilities; or (vii) any
other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a guarantor.

                  (f) No payment made by or for the account of a Borrower
including, without limitations, (i) a payment made by such Borrower on behalf of
another Borrower's Liabilities or (ii) a payment made by any other person under
any guaranty, shall entitle such Borrower, by subrogation or otherwise, to any
payment from such other Borrower or from or out of such other Borrower's
property and such Borrower shall not exercise any right or remedy against such
other Borrower or any property of such other Borrower by reason of any
performance of such Borrower of its joint and several obligations hereunder.

                  19. INDEMNIFICATION.

                  Each Borrower agrees to defend (with counsel satisfactory to
Lender), protect, indemnify and hold harmless Lender, each affiliate or
subsidiary of Lender, and each of their respective shareholders, members,
officers, directors, managers, employees, attorneys and

                                      -43-
<PAGE>

agents (each an "INDEMNIFIED PARTY") from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, claims,
costs, expenses and disbursements of any kind or nature (including, without
limitation, the disbursements and the reasonable fees of counsel for each
Indemnified Party in connection with any investigative, administrative or
judicial proceeding, whether or not the Indemnified Party shall be designated a
party thereto), which may be imposed on, incurred by, or asserted against, any
Indemnified Party (whether direct, indirect or consequential and whether based
on any federal, state or local laws or regulations, including, without
limitation, securities laws and regulations, Environmental Laws and commercial
laws and regulations, under common law or in equity, or based on contract or
otherwise) in any manner relating to or arising out of this Agreement or any
Other Agreement, or any act, event or transaction related or attendant thereto,
the making or issuance and the management of the Loans or any Letters of Credit
or the use or intended use of the proceeds of the Loans or any Letters of
Credit; provided, however, that no Borrower shall have any obligation hereunder
to any Indemnified Party with respect to matters caused by or resulting from the
willful misconduct or gross negligence of such Indemnified Party. To the extent
that the undertaking to indemnify set forth in the preceding sentence may be
unenforceable because it is violative of any law or public policy, each Borrower
shall satisfy such undertaking to the maximum extent permitted by applicable
law. Any liability, obligation, loss, damage, penalty, cost or expense covered
by this indemnity shall be paid to each Indemnified Party on demand, and,
failing prompt payment, shall, together with interest thereon at the highest
rate then applicable to Loans hereunder from the date incurred by each
Indemnified Party until paid by Borrowers, be added to the Liabilities of
Borrowers and be secured by the Collateral. The provisions of this Section 18
shall survive the satisfaction and payment of the other Liabilities and the
termination of this Agreement.

                  20. NOTICE.

                  All written notices and other written communications with
respect to this Agreement shall be sent by ordinary, certified or overnight
mail, by telecopy or delivered in person, and in the case of Lender shall be
sent to it at 135 South LaSalle Street, Chicago, Illinois 60603-4105, attention:
Susan Hamilton, facsimile number: (312) 904-6450, and in the case of Borrowers
shall be sent to them at their respective principal places of business set forth
on Exhibit A hereto or as otherwise directed by Borrowers in writing. All
notices shall be deemed received upon actual receipt thereof or refusal of
delivery.

                  21. CHOICE OF GOVERNING LAW; CONSTRUCTION; FORUM SELECTION.

                  This Agreement and the Other Agreements are submitted by
Borrowers to Lender for Lender's acceptance or rejection at Lender's principal
place of business as an offer by Borrowers to borrow monies from Lender now and
from time to time hereafter, and shall not be binding upon Lender or become
effective until accepted by Lender, in writing, at said place of business. If so
accepted by Lender, this Agreement and the Other Agreements shall

                                      -44-
<PAGE>

be deemed to have been made at said place of business. THIS AGREEMENT AND THE
OTHER AGREEMENTS SHALL BE GOVERNED AND CONTROLLED BY THE INTERNAL LAWS OF THE
STATE OF ILLINOIS AS TO INTERPRETATION, ENFORCEMENT, VALIDITY, CONSTRUCTION,
EFFECT, AND IN ALL OTHER RESPECTS, INCLUDING, WITHOUT LIMITATION, THE LEGALITY
OF THE INTEREST RATE AND OTHER CHARGES, BUT EXCLUDING PERFECTION OF THE SECURITY
INTERESTS IN COLLATERAL LOCATED OUTSIDE OF THE STATE OF ILLINOIS, WHICH SHALL BE
GOVERNED AND CONTROLLED BY THE LAWS OF THE RELEVANT JURISDICTION IN WHICH SUCH
COLLATERAL IS LOCATED. If any provision of this Agreement shall be held to be
prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or remaining provisions of this
Agreement.

                  To induce Lender to accept this Agreement, each Borrower
irrevocably agrees that, subject to Lender's sole and absolute election, ALL
ACTIONS OR PROCEEDINGS IN ANY WAY, MANNER OR RESPECT, ARISING OUT OF OR FROM OR
RELATED TO THIS AGREEMENT, THE OTHER AGREEMENTS OR THE COLLATERAL SHALL BE
LITIGATED IN COURTS HAVING SITUS WITHIN THE CITY OF CHICAGO, STATE OF ILLINOIS.
EACH BORROWER HEREBY CONSENTS AND SUBMITS TO THE JURISDICTION OF ANY LOCAL,
STATE OR FEDERAL COURTS LOCATED WITHIN SAID CITY AND STATE. EACH BORROWER HEREBY
WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS AND AGREES THAT ALL SUCH SERVICE
OF PROCESS MAY BE MADE UPON SUCH BORROWER BY CERTIFIED OR REGISTERED MAIL,
RETURN RECEIPT REQUESTED, ADDRESSED TO SUCH BORROWER, AT THE ADDRESS SET FORTH
FOR NOTICE IN THIS AGREEMENT AND SERVICE SO MADE SHALL BE COMPLETE TEN (10) DAYS
AFTER THE SAME HAS BEEN POSTED. Lender agrees to endeavor to provide a copy of
such process to the law firm of Gray, Layton, Kersh, Solomon, Sigmon, Furr &
Smith, P.A. by mail at the address of 516 South New Hope Road, Gastonia, North
Carolina 28053-2636 or by facsimile transmission at facsimile number (704)
866-8010. Failure of Lender to provide a copy of such process shall not impair
Lender's rights hereunder, create a cause of action against Lender or create any
claim or right on behalf of Borrowers or any third party. EACH BORROWER HEREBY
WAIVES ANY RIGHT IT MAY HAVE TO TRANSFER OR CHANGE THE VENUE OF ANY LITIGATION
BROUGHT AGAINST SUCH BORROWER BY LENDER IN ACCORDANCE WITH THIS SECTION.

                  22. MODIFICATION AND BENEFIT OF AGREEMENT.

                  This Agreement and the Other Agreements may not be modified,
altered or amended except by an agreement in writing signed by each Borrower or
such other Person who is a party to such Other Agreement and Lender. No Borrower
may sell, assign or transfer this Agreement, or the Other Agreements or any
portion thereof, including, without

                                      -45-
<PAGE>

limitation, such Borrower's rights, titles, interest, remedies, powers or duties
hereunder and thereunder. Each Borrower hereby consents to Lender's sale,
assignment, transfer or other disposition, at any time and from time to time
hereafter, of this Agreement, or the Other Agreements, or of any portion
thereof, or participations therein, including, without limitation, Lender's
rights, titles, interest, remedies, powers and/or duties and agrees that it
shall execute and deliver such documents as Lender may request in connection
with any such sale, assignment, transfer or other disposition.

                  23. HEADINGS OF SUBDIVISIONS.

                  The headings of subdivisions in this Agreement are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of this Agreement.

                  24. POWER OF ATTORNEY.

                  Each Borrower acknowledges and agrees that its appointment of
Lender as its attorney and agent-in-fact for the purposes specified in this
Agreement is an appointment coupled with an interest and shall be irrevocable
until all of the Liabilities are satisfied and paid in full and this Agreement
is terminated.

                  25. CONFIDENTIALITY.

                  Lender hereby agrees to use commercially reasonable efforts to
assure that any and all information relating to such Borrower which is (i)
furnished by such Borrower to Lender (or to any affiliate of Lender); and (ii)
non-public, confidential or proprietary in nature, shall be kept confidential by
Lender or such affiliate in accordance with applicable law; provided, however,
that such information and other credit information relating to such Borrower may
be distributed by Lender or such affiliate to Lender's or such affiliate's
directors, managers, officers, employees, attorneys, affiliates, assignees,
participants, auditors, agents and regulators, and upon the order of a court or
other governmental agency having jurisdiction over Lender or such affiliate, to
any other party. Each Borrower and Lender further agree that this provision
shall survive the termination of this Agreement. Notwithstanding the foregoing,
each Borrower hereby consents to Lender publishing a tombstone or similar
advertising material relating to the financing transaction contemplated by this
Agreement. Notwithstanding anything to the contrary set forth herein or in any
other agreement to which the parties hereto are parties or by which they are
bound, the obligations of confidentiality contained herein and therein, as they
relate the transactions contemplated by this Agreement and the Other Agreements
(the "Transaction"), shall not apply to the federal tax structure or federal tax
treatment of the Transaction, and each party hereto (and any employee,
representative, agent or any party hereto) may disclose to any and all persons,
without limitation of any kind, the federal tax structure and federal tax
treatment of the Transaction. In addition, each party hereto acknowledges that
it has no proprietary or

                                      -46-
<PAGE>

exclusive rights to the federal tax structure of the Transaction or any federal
tax matter or federal tax treatment related to the Transaction.

                  26. COUNTERPARTS.

                  This Agreement, any of the Other Agreements and any
amendments, waivers, consents or supplements may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which, when so executed and delivered, shall be deemed an original, but all of
which counterparts together shall constitute but one agreement.

                  27. ELECTRONIC SUBMISSIONS.

                  Upon not less than thirty (30) days' prior written notice (the
"APPROVED ELECTRONIC FORM NOTICE"), Lender may permit or require that any of the
documents, certificates, forms, deliveries or other communications, authorized,
required or contemplated by this Agreement or the Other Agreements, be submitted
to Lender in "APPROVED ELECTRONIC FORM" (as hereafter defined), subject to any
reasonable terms, conditions and requirements in the applicable Approved
Electronic Forms Notice. For purposes hereof "ELECTRONIC FORM" means e-mail,
e-mail attachments, data submitted on web-based forms or any other communication
method that delivers machine readable data or information to Lender, and
"APPROVED ELECTRONIC FORM" means an Electronic Form that has been approved in
writing by Lender (which approval has not been revoked or modified by Lender)
and sent to Borrowers in an Approved Electronic Form Notice. Except as otherwise
specifically provided in the applicable Approved Electronic Form Notice, any
submissions made in an applicable Approved Electronic Form shall have the same
force and effect that the same submissions would have had if they had been
submitted in any other applicable form authorized, required or contemplated by
this Agreement or the Other Agreements.

                  28. WAIVER OF JURY TRIAL; OTHER WAIVERS.

                  (a) EACH BORROWER AND LENDER EACH HEREBY WAIVES ALL RIGHTS TO
TRIAL BY JURY IN ANY ACTION OR PROCEEDING WHICH PERTAINS DIRECTLY OR INDIRECTLY
TO THIS AGREEMENT, ANY OF THE OTHER AGREEMENTS, THE LIABILITIES, THE COLLATERAL,
ANY ALLEGED TORTIOUS CONDUCT BY A BORROWER OR LENDER OR WHICH, IN ANY WAY,
DIRECTLY OR INDIRECTLY, ARISES OUT OF OR RELATES TO THE RELATIONSHIP BETWEEN A
BORROWER AND LENDER. IN NO EVENT SHALL LENDER BE LIABLE FOR LOST PROFITS OR
OTHER SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES.

                  (b) Each Borrower hereby waives demand, presentment, protest
and notice of nonpayment, and further waives the benefit of all valuation,
appraisal and exemption laws.

                                      -47-
<PAGE>

                  (c) Each Borrower hereby waives the benefit of any law that
would otherwise restrict or limit Lender or any affiliate of Lender in the
exercise of its right, which is hereby acknowledged and agreed to, to set-off
against the Liabilities, without notice at any time hereafter, any indebtedness,
matured or unmatured, owing by Lender or such affiliate of Lender to such
Borrower, including, without limitation any Deposit Account at Lender or such
affiliate.

                  (d) EACH BORROWER HEREBY WAIVES ALL RIGHTS TO NOTICE AND
HEARING OF ANY KIND PRIOR TO THE EXERCISE BY LENDER OF ITS RIGHTS TO REPOSSESS
THE COLLATERAL OF SUCH BORROWER WITHOUT JUDICIAL PROCESS OR TO REPLEVY, ATTACH
OR LEVY UPON SUCH COLLATERAL, PROVIDED THAT IN THE EVENT THAT LENDER SEEKS TO
ENFORCE ITS RIGHTS HEREUNDER BY JUDICIAL PROCESS OR SELF HELP, LENDER SHALL
PROVIDE BORROWERS WITH SUCH NOTICES AS ARE REQUIRED BY LAW.

                  (e) Lender's failure, at any time or times hereafter, to
require strict performance by a Borrower of any provision of this Agreement or
any of the Other Agreements shall not waive, affect or diminish any right of
Lender thereafter to demand strict compliance and performance therewith. Any
suspension or waiver by Lender of an Event of Default under this Agreement or
any default under any of the Other Agreements shall not suspend, waive or affect
any other Event of Default under this Agreement or any other default under any
of the Other Agreements, whether the same is prior or subsequent thereto and
whether of the same or of a different kind or character. No delay on the part of
Lender in the exercise of any right or remedy under this Agreement or any Other
Agreement shall preclude other or further exercise thereof or the exercise of
any right or remedy. None of the undertakings, agreements, warranties, covenants
and representations of Borrowers contained in this Agreement or any of the Other
Agreements and no Event of Default under this Agreement or default under any of
the Other Agreements shall be deemed to have been suspended or waived by Lender
unless such suspension or waiver is in writing, signed by a duly authorized
officer of Lender and directed to Borrowers specifying such suspension or
waiver.
