and health plans that are fully funded through commercial insurance); and (ii)
any defined benefit "employee pension benefit plans" (as defined in ERISA).
Neither Borrower nor, to the best knowledge of Borrower, any other person has

Borrower or the Lender to a penalty under ERISA or a tax under the Internal
Revenue Code of 1986, as amended (the "Code"), except for those transactions
which could not reasonably be expected to have a Material Adverse Effect. Each

has been operated and administered in accordance with applicable law, including
without limitation ERISA, except for any such failure which would not subject
Borrower or the Lender to any penalty or other liability and except for any such
failure which would not have an adverse effect upon the applicable plan or any
participant therein. Borrower has not incurred, nor presently expects to incur,
any liability under Title IV of ERISA that could result in liability to the
Lenders or Borrower. Each employee benefit plan listed or required to be listed
on Schedule 4.14 that is a group health plan within the meaning of Section
5000(b)(1) of the Code, is in compliance with the provisions of Section 4980B(f)
of the Code, except for any such non-compliance which would not subject Borrower
or the Lender to any penalty or liability and except for any such failure which
would not have an adverse effect upon the applicable plan or any participant
therein. There is not any pending or, to the best knowledge of Borrower,
threatened claim by or on behalf of any employee benefit plan, by any employee
covered under any such plan or otherwise involving any employee benefit plan
(other than routine non-contested claims for benefits).

Subsidiary is in violation of any law, regulation or ordinance relating to its
business, operations and properties which, individually or in the aggregate,
could have a Material Adverse Effect, and the business and operations of
Borrower or any Subsidiary do not violate, in any material respect, any federal,
state, local or foreign laws, regulations or orders. Except as set forth on

communication from any federal, state, local or foreign governmental or
regulatory authority or agency including without limitation, the U.S. Food and

leased under any lease which the Lender has agreed to assume is subject to any
lien, encumbrance, easement, right-of-way, building or use restriction,
exception, variance, reservation or limitation as might in any respect
interfere with or impair the present and continued use thereof in the usual

are asserted against any Indemnitee if the claim, demand, action or cause of
action, directly or indirectly, relates to this Agreement and the other Loan
Documents issued pursuant thereto, the use of proceeds of the Loans, or the
relationship of Borrower and the Lender under this Agreement or any transaction
contemplated pursuant to this Agreement, (ii) any administrative or
investigative proceeding by any Governmental Authority, directly or indirectly,
related to a claim, demand, action or cause of action described in clause (i)
above, and (iii) any and all liabilities, losses, costs or expenses (including
reasonable attorneys' fees and disbursements) that any Indemnitee suffers or
incurs as a result of any of the foregoing; PROVIDED, HOWEVER, that Borrower
shall have no obligation under this Section 5.16 to the Lender with respect to
any of the foregoing arising out of the gross negligence or willful misconduct
of the Lender or its assignees or the breach by Lender or its assignees of this
Agreement or any other Loan Document or other document executed in connection
with any of the aforesaid, the breach by the Lender or its assignees of any
intercreditor or participation agreement or commitment with other parties, the
violation or alleged violation of any law, rule or regulation by the Lender or
its assignees, or from the transfer or disposition by the Lender of any
Debentures or the Common Stock issued upon conversion of the Debentures. If any
claim, demand, action or cause of action is asserted against any Indemnitee,
such Indemnitee shall promptly notify Borrower, but the failure to so promptly
notify Borrower shall not affect Borrower's obligations under this Section
unless such failure materially prejudices Borrower's right or ability to
participate in the contest of such claim, demand, action or cause of action, as
hereinafter provided. In the event that such Indemnitee's failure to properly
notify Borrower materially prejudices Borrower's right or ability to participate
in the contest of such claim, demand action or cause of action, then said
Indemnitee shall have no right to receive, and Borrower shall have no obligation
to pay, any indemnification amounts hereunder. Borrower may elect to defend any
such claim, demand, action or cause of action (at its own expense) asserted
against said Indemnitee and, if requested by Borrower in writing and so long as
no Default or Event of Default shall have occurred and be continuing, such
Indemnitee (at Borrower's expense) shall, in good faith, contest the validity,
applicability and amount of such claim, demand, action or cause of action and
shall permit Borrower to participate in such contest. Any Indemnitee that
proposes to settle or compromise any claim or proceeding for which Borrower may
be liable, for payment to or on behalf of an Indemnitee hereunder, shall give
Borrower written notice of the terms of such proposed settlement or compromise
reasonably in advance of settling or compromising such claim or proceeding and
shall obtain Borrower's written concurrence thereto. In the event that said
Indemnitee fails to obtain Borrower's prior written consent to any such
settlement or compromise, said Indemnitee shall have no right to receive, and
Borrower shall have no obligation to pay, any indemnification amounts hereunder.
Each Indemnitee may employ counsel, which counsel shall be reasonably acceptable
to Borrower, in enforcing its rights hereunder and in defending against any
claim, demand, action or cause of action covered by this Section 5.16; PROVIDED,
HOWEVER, that each Indemnitee

                                      26
<PAGE>

Agreement (Continued)
--------------------------------------------------------------------------------

shall endeavor in connection with any matter covered by this Section 5.16 which
also involves any other Indemnitee, use reasonable efforts to avoid unnecessary
duplication of effort by counsel for all Indemnitees, including allowing
Borrower to select one lawyer for all parties, such selection to be subject to
the approval of such parties, which approval shall not be unreasonably
withheld. Any obligation or liability of Borrower to any Indemnitee under this
Section 5.16 shall survive the expiration or termination of this Agreement and
the repayment of the Debentures.

excess of $5.00 per share.

forthwith due and payable, whereupon the same shall forthwith become due and
payable without presentment, demand, protest, notice of default, notice of
acceleration or of intention to accelerate or other notice of any kind, all of
which Borrower hereby expressly waives, anything contained herein or in the
Debentures to the contrary notwithstanding;

             (ii) reduce any claim to judgment; and

             (iii) without notice of default or demand, pursue and enforce
any of the Lender's rights and remedies under the Loan Documents and the
Subsidiary Documents, or otherwise provided under or pursuant to any applicable
law or agreement, all of which rights may be specifically enforced.

         (b) In the event of a violation by Borrower of the negative covenants
set forth in Article VI, the Lender may, in its sole discretion, (i) waive
compliance with the covenants, provided Borrower is in compliance with Section
7.01 hereof; or (ii) require Borrower to redeem the Debentures at the higher of
market value or the unpaid principal amount of the Debentures, together with an
amount equal to an 18% annual yield on the principal amount through the
Redemption Date, whichever is greater.

SECTION 8.03 PERFORMANCE BY THE LENDER.

         Should Borrower or any Subsidiary fail to perform any covenant, duty or
agreement contained herein or in any of the other Loan Documents or in any
Subsidiary Document, Lender or Agent may perform or attempt to perform such
covenant, duty or agreement on behalf of Borrower. In such event, Borrower
shall, at the request of Lender or Agent, promptly pay any amount reasonably
expended by Lender or Agent in such performance or attempted performance to
Lender or Agent at its principal office, together with interest thereon, at the
interest rate specified in the Debentures, from the date of such expenditure
until paid. Notwithstanding the foregoing, it is expressly understood that
Lender or Agent assumes no liability or responsibility for the performance of
any duties of Borrower or any Subsidiary hereunder or under any of the other
Loan Documents or under any Subsidiary Document.

SECTION 8.04 PAYMENT OF EXPENSES INCURRED BY THE LENDER.

         Upon the occurrence of a Default or an Event of Default, which
occurrence is not cured within the notice provisions, if any, provided herein,
Borrower agrees to pay and shall pay all costs and expenses (including
reasonable attorneys' fees and expenses) incurred by Lender or Agent in
connection with the preservation and enforcement of the Lender's rights under
this Agreement, the Debentures or any other Loan Document.

                       ARTICLE IX. - REGISTRATION RIGHTS

SECTION 9.01 DEMAND REGISTRATION.

         (a)      Borrower hereby agrees to register all or any portion of the
Registrable Securities on one occasion if, and only if, it shall receive a
written request from a Holder (the "Initiating Holder") that Borrower file a
registration statement under the 1933 Act covering the registration of at
least 25% of the Registrable Securities Then Outstanding. Borrower shall,
within 20 days of its receipt thereof, give written notice of such request to
all Holders of record of Registrable Securities. The Holders of said
Registrable Securities shall then have 15 days from the date of mailing of
such notice by Borrower to request that all or a portion of their respective
Registrable Securities be included in said registration.

         (b)      If the Holders intend to distribute the Registrable
Securities covered by their request by means of a firm underwriting, they
shall so advise Borrower as a part of their request made pursuant to this
Agreement, and Borrower shall include such information in the written notice
to the other Holders of Registrable Securities referred to in Section 9.01(a).
In such event, the right of any Holder to include its Registrable Securities
in such registration shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by Borrower, the
underwriter, the Initiating Holder and such Holder) is limited to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall (together with Borrower as provided in Section
9.04(e)) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by mutual agreement
of Borrower and the Initiating Holder, which agreement shall not be
unreasonably withheld. Notwithstanding any other provision of this Section
9.01, if the underwriter advises the Initiating Holder and Borrower in writing
that marketing factors require a limitation of the number of shares to be
underwritten, then the Initiating Holder shall so advise all Holders of
Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares of Registrable Securities that may be included in the
underwriting shall be allocated on a pro rata basis among all Holders that
have requested to participate in such registration. The rights of the Holders
shall be PARI PASSU to those of any other Persons previously granted demand
registration rights and senior to those of any other Person subsequently
granted demand registration rights.

         (c)      Each such registration shall remain effective for a period
of 180 days, unless the Initiating Holder otherwise determines.
Notwithstanding the foregoing, if the Holders' elect not to sell all or any
portion of the Registrable Securities pursuant to a demand registration which
has become effective, such demand registration right shall nonetheless be
deemed satisfied.

         (d)      If, after a registration statement becomes effective,
Borrower advises the Holders that the registration statement is required to be
amended under applicable federal securities laws, the Holders shall suspend
any further sales of their Registrable Securities, until the Company advises
them that the

                                      33

<PAGE>

Agreement (Continued)
--------------------------------------------------------------------------------

registration statement has been amended, but not more than thirty (30) days.
The 180-day time period referred to in subsection (c) during which the
registration statement must be kept current after its effective date shall be
extended for an additional number of business days equal to the number of
business days during which the right to sell the Registrable Securities was
suspended pursuant to the preceding sentence.

         (e)      No demand for registration may be made for a one hundred
eighty (180)-day period following completion of another underwritten offering
of Borrower's equity securities.

SECTION 9.02 "PIGGY-BACK" REGISTRATION.

         If Borrower proposes to register any of its capital stock under the
1933 Act in connection with the public offering of such securities for its own
account or for the account of its security holders, other than Holders of
Registrable Securities pursuant hereto (a "Piggy-Back Registration Statement"),
except for (i) a registration relating solely to the sale of securities to
participants in Borrower's stock or stock option plans or employee benefit plans
or (ii) a registration relating solely to a transaction for which Form S-4 may
be used, then:

         (a)      Borrower shall give written notice of such determination to
each Holder of Registrable Securities, and each such Holder shall have the
right to request, by written notice given to Borrower within 15 days of the
date that such written notice was mailed by Borrower to such Holder, that a
specific number of Registrable Securities held by such Holder be included in
the Piggy-Back Registration Statement (and related underwritten offering, if
any) and the states in which such Registrable Securities are to be sold;

         (b)      If the Piggy-Back Registration Statement relates to an
underwritten offering, the notice given to each Holder shall specify the name
or names of the managing underwriter or underwriters for such offering. In
addition, such notice shall also specify the number of securities to be
registered for the account of Borrower and for the account of its shareholders
(other than the Holders of Registrable Securities), if any;

         (c)      If the Piggy-Back Registration Statement relates to an
underwritten offering, each Holder of Registrable Securities to be included
therein must agree (i) to sell such Holder's Registrable Securities on the
same basis as provided in the underwriting arrangement approved by Borrower,
and (ii) to timely complete and execute all questionnaires, powers of
attorney, indemnities, hold-back agreements, lock-up agreements, underwriting
agreements and other documents required under the terms of such underwriting
arrangements or by the SEC or by any state securities regulatory body;

         (d)      If the managing underwriter or underwriters for the
underwritten offering under the Piggy-Back Registration Statement determines
that inclusion of all or any portion of the Registrable Securities in such
offering would materially adversely affect the ability of the underwriters for
such offering to sell all of the securities requested to be included for sale
in such offering at the best price obtainable therefor, the aggregate number
of Registrable Securities that may be sold by the Holders shall be limited to
such number of Registrable Securities, if any, that the managing underwriter
or underwriters determine may be included therein without such adverse effect
as provided below. If the number of securities proposed to be sold in such
underwritten offering exceeds the number of securities that may be sold in
such offering, there shall be included in the offering, first, up to the
maximum number of securities to be sold by Borrower for its own account and
for the account of other stockholders (other than

                                      34

<PAGE>

Agreement (Continued)
--------------------------------------------------------------------------------

Holders of Registrable Securities), as they may agree among themselves, and
second, as to the balance, if any, Registrable Securities requested to be
included therein by the Holders thereof (pro rata as between such Holders
based upon the number of Registrable Securities initially proposed to be
registered by each), or in such other proportions as the managing underwriter
or underwriters for the offering may require; PROVIDED, HOWEVER, that in the
event that the number of securities proposed to be sold in such underwritten
offering exceeds the number of securities that may be sold in such offering
pursuant to the terms and conditions set forth above and the Piggy-Back
Registration Statement is a result of public offering by Borrower of its
securities for its own account, there shall be included in the offering,
first, up to the maximum number of securities to be sold by Borrower for its
own account and second, as to the balance, if any, securities to be sold for
the account of Borrower's stockholders (both the Holders of Registrable
Securities requested and such other stockholders of Borrower requested to be
included therein) on a PRO RATA basis;

         (e)      Holders of Registrable Securities shall have the right to
withdraw their Registrable Securities from the Piggy-Back Registration
Statement, but if the same relates to an underwritten offering, they may only
do so during the time period and on the terms agreed upon among the
underwriters for such underwritten offering and the Holders of Registrable
Securities;

         (f)      The exercise of the registration rights of the Holders with
respect to any specific underwritten offering shall be subject to a 90-day
delay at the request of the managing underwriter;

         (g)      All demand and piggy-back registration rights of the Holders
shall terminate when all of the Registrable Securities Then Outstanding may be
sold pursuant to Rule 144(k).

SECTION 9.03 SHELF REGISTRATION.

         Borrower shall file a "shelf" registration statement on Form S-3 under
the 1933 Act (the "Shelf Registration") covering all of the Registrable
Securities within 180 days of the date of the Debentures, and Borrower shall use
its best efforts to cause the Shelf Registration to be declared effective and to
keep the Shelf Registration continuously effective until all of the Registrable
Securities registered therein cease to be Registrable Securities. The securities
shall cease to be Registrable Securities (a) when the Shelf Registration shall
have become effective under the 1933 Act and such securities shall have been
disposed of pursuant to the Shelf Registration, or (b) such securities shall
have been sold as permitted by Rule 144 under the 1933 Act or the date on which
the Registrable Securities may be sold pursuant to Rule 144(k), whichever is the
first to occur. Borrower agrees, if necessary, to supplement or amend the Shelf
Registration, as required by the registration form utilized by Borrower or by
the instructions applicable to such registration form or by the 1933 Act, and
Borrower agrees to furnish to the holders of the Registrable Securities copies
of any such supplement or amendment prior to its being used.

SECTION 9.04 OBLIGATIONS OF BORROWER.

         Whenever required to effect the registration of any Registrable
Securities pursuant to this Agreement, Borrower shall, as expeditiously as
reasonably possible:

         (a)      Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use all reasonable efforts to cause
such registration statement to become effective, subject to the receipt of all
required information from the Holders, and keep such registration statement
effective until the sooner of all such Registrable Securities having been
distributed, or until 120 days have elapsed

                                      35

<PAGE>

Agreement (Continued)
--------------------------------------------------------------------------------

since such registration statement became effective (subject to an extension of
this period as provided below);

         (b)      Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the 1933 Act with respect to the disposition of all
securities covered by such registration statement, or 120 days have elapsed
since such registration statement became effective (subject to the extension
of this period as provided below);

         (c)      Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by them;

         (d)      Use all reasonable efforts to register and qualify the
securities covered by such registration statement under such other securities
or Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that Borrower shall not be required, in connection therewith
or as a condition thereto, to qualify as a broker-dealer in any states or
jurisdictions or to do business or to file a general consent to service of
process in any such states or jurisdictions;

         (e)      In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement with the managing
underwriter of such offering, in usual and customary form reasonably
satisfactory to Borrower and the Holders of a majority of the Registrable
Securities to be included in such offering. Each Holder participating in such
underwriting shall also enter into and perform its obligations under such an
agreement;

         (f)      Notify each Holder of Registrable Securities covered by such
registration statement, at any time when a prospectus relating thereto and
covered by such registration statement is required to be delivered under the
1933 Act, of the happening of any event as a result of which the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
the light of the circumstances then existing; and

         (g)      In the event of the notification provided for in Section
9.04(f) above, Borrower shall use its best efforts to prepare and file with
the SEC (and to provide copies thereof to the Holders) as soon as reasonably
possible an amended prospectus complying with the 1933 Act, and the period
during which the prospectus referred to in the notice provided for in Section
9.04(f) above cannot be used and the time period prior to the use of the
amended prospectus referred to in this Section 9.04(g) shall not be counted in
the 120 day period of this Section 9.04.

SECTION 9.05 FURNISH INFORMATION.

         (a)      It shall be a condition precedent to the obligations of
Borrower to take any action pursuant to this Article IX that the selling
Holders shall furnish to Borrower any and all information reasonably requested
by Borrower, its officers, directors, employees, counsel, agents or
representatives, the underwriter or underwriters, if any, and the SEC or any
other Governmental Authority, including, but not limited to: (i) such
information regarding themselves, the Registrable Securities held by them, and
the intended method of disposition of such securities, as shall be required to
effect the registration of their

                                      36

<PAGE>

Agreement (Continued)
--------------------------------------------------------------------------------

Registrable Securities; and (ii) the identity of and compensation to be paid
to any proposed underwriter or broker-dealer to be employed in connection
therewith.

         (b)      In connection with the preparation and filing of each
registration statement registering Registrable Securities under the 1933 Act,
Borrower shall give the Holders of Registrable Securities on whose behalf such
Registrable Securities are to be registered and their underwriters, if any,
and their respective counsel and accountants, at such Holders' sole cost and
expense (except as otherwise set forth herein), such access to copies of
Borrower's records and documents and such opportunities to discuss the
business of Borrower with its officers and the independent public accountants
who have certified its financial statements as shall be reasonably necessary
in the opinion of such Holders and such underwriters or their respective
counsel, to conduct a reasonable investigation within the meaning of the 1933
Act.

SECTION 9.06 EXPENSES OF REGISTRATION.

         Except for a demand registration statement, the cost of which shall be
borne by the Holders participating in such registration, all expenses, other
than underwriting discounts and commissions applicable to the Registrable
Securities sold by selling Holders, incurred in connection with the registration
of the Registrable Securities pursuant to this Article, including, without
limitation, all registration, filing and qualification fees, printer's expenses,
and accounting and legal fees and expenses of Borrower, shall be borne by
Borrower; provided, however, selling Holders shall be responsible for all costs
of their due diligence and legal counsel and other advisors in connection with a
registration of Registrable Securities.

SECTION 9.07 INDEMNIFICATION REGARDING REGISTRATION RIGHTS.

         If any Registrable Securities are included in a registration statement
under this Article:

         (a)      To the extent permitted by law, Borrower will indemnify and
hold harmless each Holder, the officers and directors of each Holder, any
underwriter (as defined in the 1933 Act) for such Holder and each person, if
any, who controls such Holder or underwriter within the meaning of the 1933
Act or the 1934 Act, against any losses, claims, damages, liabilities (joint
or several) or any legal or other costs and expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim,
damage, liability or action to which they may become subject under the 1933
Act, the 1934 Act or state law, insofar as such losses, claims, damages,
costs, expenses or liabilities (or actions in respect thereof) arise out of or
are based upon any of the following statements, omissions or violations (each
a "Violation"): (i) any untrue statement or alleged untrue statement of a
material fact with respect to Borrower or its securities contained in such
registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements therein; (ii)
the omission or alleged omission to state therein a material fact with respect
to Borrower or its securities required to be stated therein or necessary to
make the statements therein not misleading; or (iii) any violation or alleged
violation by Borrower of the 1933 Act, the 1934 Act, any state securities law
or any rule or regulation promulgated under the 1933 Act, the 1934 Act or any
state securities law. Notwithstanding the foregoing, the indemnity agreement
contained in this Section 9.07(a) shall not apply and Borrower shall not be
liable (i) in any such case for any such loss, claim, damage, costs, expenses,
liability or action to the extent that it arises out of or is based upon a
Violation which occurs in reliance upon, and in conformity with, written
information furnished expressly for use in connection with such registration
by any such Holder or its authorized agent, underwriter or controlling person,
or (ii) for amounts paid in settlement of any such

                                      37

<PAGE>

Agreement (Continued)
--------------------------------------------------------------------------------

loss, claim, damage, liability or action if such settlement is effected
without the prior written consent of Borrower, which consent shall not be
unreasonably withheld.

         (b)      To the extent permitted by law, each Holder who participates
in a registration pursuant to the terms and conditions of this Agreement shall
indemnify and hold harmless Borrower, each of its directors and officers who
have signed the registration statement, each Person, if any, who controls
Borrower within the meaning of the 1933 Act, the 1934 Act, any state
securities law or any rule or regulation promulgated under the 1933 Act, the
1934 Act or any state securities law, each of Borrower's employees, agents,
counsel and representatives, any underwriter and any other Holder selling
securities in such registration statement, or any of its directors or
officers, or any person who controls such Holder, against any losses, claims,
damages, costs, expenses or liabilities (joint or several) to which Borrower
or any such director, officer, controlling person, employee, agent,
representative, underwriter or other such Holder, or director, officer or
controlling person thereof, may become subject, under the 1933 Act, the 1934
Act or other federal or state law, only insofar as such losses, claims,
damages, costs, expenses or liabilities or actions in respect thereto arise
out of or are based upon any Violation, in each case to the extent, and only
to the extent, that such Violation occurs in reliance upon and in conformity
with written information furnished by such Holder expressly for use in
connection with such Registration. Each such Holder will indemnify any legal
or other expenses reasonably incurred by Borrower or any such director,
officer, employee, agent, representative, controlling person, underwriter or
other Holder, or officer, director or any controlling person thereof, in
connection with investigating or defending any such loss, claim, damage,
liability or action; PROVIDED, HOWEVER, that the indemnity agreement contained
in this Section 9.07(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, costs, expenses, liability or action if such
settlement is effected without the prior written consent of the Holder, which
consent shall not be unreasonably withheld.

         (c)      Promptly after receipt by an indemnified party under this
Section 9.07 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 9.07,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party
shall have the right to retain its own counsel, with the reasonable fees and
expenses of such counsel to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential conflict
of interests between such indemnified party and any other party represented by
such counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve the indemnifying party of its obligations under this
Section 9.07, except to the extent that the failure results in a failure of
actual notice to the indemnifying party and such indemnifying party is
materially prejudiced in its ability to defend such action solely as a result
of the failure to give such notice.

         (d)      If the indemnification provided for in this Section 9.07 is
unavailable to an indemnified party under this Section in respect of any
losses, claims, damages, costs, expenses, liabilities or actions referred to
herein, then each indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages, costs, expenses,
liabilities or actions in such proportion as is appropriate to reflect the
relative fault of Borrower, on the one hand and of the Holder, on the other,
in connection with the Violation that resulted in such losses, claims,
damages, costs, expenses, liabilities or actions. The relative fault of

                                      38

<PAGE>

Agreement (Continued)
--------------------------------------------------------------------------------

Borrower, on the one hand, and of the Holder, on the other, shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of the material fact or the omission to state a material fact
relates to information supplied by Borrower or by the Holder, and the parties'
relative intent, knowledge, access to information and opportunity to correct
or prevent such statement or omission.

         (e)      Borrower, on the one hand, and the Holders, on the other,
agree that it would not be just and equitable if contribution pursuant to this
Section 9.07 were determined by a PRO RATA allocation or by any other method
of allocation which does not take account of the equitable considerations
referred to in the immediately preceding paragraph. The amount paid or payable
by an indemnified party as a result of losses, claims, damages, costs,
expenses, liabilities and actions referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any reasonable legal or other expenses incurred by such indemnified
party in connection with defending any such action or claim. Notwithstanding
the provisions of this Section 9.07, neither Borrower nor the Holders shall be
required to contribute any amount in excess of the amount by which the total
price at which the securities were offered to the public exceeds the amount of
any damages which Borrower or each such Holder has otherwise been required to
pay by reason of such Violation. No person guilty of fraudulent
misrepresentations (within the meaning of Section 11(f) of the 1933 Act) shall
be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation.

SECTION 9.08 REPORTS UNDER THE 1934 ACT.

         So long as Borrower has a class of securities registered pursuant to
Section 12 of the 1934 Act, with a view to making available to the Holders the
benefits of Rule 144 promulgated under the 1933 Act ("Rule 144") and any other
rule or regulation of the SEC that may at any time permit a Holder to sell
securities of Borrower to the public without registration or pursuant to a
registration on Form S-3, if applicable, Borrower agrees to use its reasonable
efforts to:

         (a)      Make and keep public information available, as those terms
are understood and defined in Rule 144, at all times;

         (b)      File with the SEC, in a timely manner, all reports and other
documents required of Borrower under the 1933 Act and the 1934 Act;

         (c)      Use its best efforts to include all Common Stock covered by
such registration statement on NASDAQ if the Common Stock is then quoted on
NASDAQ; or list all Common Stock covered by such registration statement on
such securities exchange on which any of the Common Stock is then listed; or,
if the Common Stock is not then quoted on NASDAQ or listed on any national
securities exchange, use its best efforts to have such Common Stock covered by
such registration statement quoted on NASDAQ or, at the option of Borrower,
listed on a national securities exchange if eligible for listing; and

         (d)      Furnish to any Holder, so long as the Holder owns any
Registrable Securities, (i) forthwith upon request, a copy of the most recent
annual or quarterly report of Borrower and such other SEC reports and
documents so filed by Borrower, and (ii) such other information (but not any
opinion of counsel) as may be reasonably requested by any Holder seeking to
avail himself of any rule or regulation of the SEC which permits the selling
of any such securities without registration or pursuant to such form.

SECTION 9.09 ASSIGNMENT OF REGISTRATION RIGHTS.

          Subject to the terms and conditions of this Agreement, and the
Debentures, the right to cause Borrower to register Registrable Securities
pursuant to this Agreement may be assigned by Holder to any transferee or
assignee of such securities; provided that (i) such transferee or assignee is a
transferee or assignee of at least ten percent (10%) of the Registrable
Securities, (ii) such transferee or assignee is not a Person who is a direct,
material competitor of Borrower, (iii) Borrower is, within a reasonable time
after such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; and, (iv) such assignment shall be
effective only if, immediately following such transfer, the further disposition
of such securities by the transferee or assignee is restricted under the 1933
Act; it being the intention that, so long as Holder holds any Registrable
Securities hereunder, either Holder or its transferee or assignee of at least
ten percent may exercise the demand right to registration and piggy-back
registration rights hereunder. Other than as set forth above, the parties hereto
hereby agree that the registration rights hereunder shall not be transferable or
assigned and any contemplated transfer or assignment in contravention of this
Agreement shall be deemed null and void and of no effect whatsoever.

SECTION 9.10 OTHER MATTERS.

         (a)      Each Holder of Registrable Securities hereby agrees by
acquisition of such Registrable Securities that, with respect to each offering
of the Registrable Securities, whether each Holder is offering such
Registrable Securities in an underwritten or nonunderwritten offering, such
Holder will comply with Regulation M or such other or additional
anti-manipulation rules then in effect until such offering has been completed,
and in respect of any nonunderwritten offering, in writing will inform
Borrower, any other Holders who are selling shareholders, and any national
securities exchange upon which the securities of Borrower are listed, that the
Registrable Securities have been sold and will, upon Borrower's request,
furnish the distribution list of the Registrable Securities. In addition, upon
the request of Borrower, each Holder will supply Borrower with such documents
and information as Borrower may reasonably request with respect to the subject
matter set forth and described in this Section 9.10.

         (b)      Each Holder of Registrable Securities hereby agrees by
acquisition of such Registrable Securities that, upon receipt of any notice
from Borrower of the happening of any event which makes any statement made in
the registration statement, the prospectus or any document incorporated
therein by reference, untrue in any material respect or which requires the
making of any changes in the registration statement, the prospectus or any
document incorporated therein by reference, in order to make the statements
therein not misleading in any material respect, such Holder will forthwith
discontinue disposition of Registrable Securities under the prospectus related
to the applicable registration statement until such Holder's receipt of the
copies of the supplemented or amended prospectus, or until it is advised in
writing by Borrower that the use of the prospectus may be resumed, and has
received copies of any additional or supplemental filings which are
incorporated by reference in the prospectus.

Agreement (Continued)
--------------------------------------------------------------------------------

the event of a monetary Default under Section 8.01 hereof, the Agent shall
have the right to designate one (1) additional nominee to serve as a member of
the Board of Directors of Borrower. Borrower will nominate and use its best
efforts to secure the election of such designee(s) as Director(s) of Borrower.
During such time as Agent has not exercised such rights, the Agent shall have
the right to designate an observer, who shall be entitled to attend and
participate (but not vote) in all meetings of the Board of Directors and to
receive all notices, reports, information, correspondence and communications
sent by Borrower to members of the Board of Directors. All reasonable and
appropriate costs and expenses incurred in connection therewith by any such
designated Director or observer, or by Agent on behalf of such Director or
observer, shall be reimbursed by Borrower.

         (b)      Any such Director or observer shall, if requested to do so,
absent himself or herself from the meeting in the event of, and so long as,
the Directors are considering and acting on matters pertaining to any rights
or obligations of Borrower or the Lender under this Agreement, the Debentures,
the other Loan Documents or the Subsidiary Documents.

SECTION 10.02 LIMITATION OF AUTHORITY OF PERSONS DESIGNATED AS A DIRECTOR
              NOMINEE.

         It is provided and agreed that the actions and advice of any person
while serving pursuant to Section 10.01 as a Director or an observer at meetings
of the Board of Directors shall be construed to be the actions and advice of
that person alone and not be construed as actions of the Lender as to any notice
of requirements or rights of Lender under this Agreement, the Debentures, the
other Loan Documents or the Subsidiary Documents nor as actions of the Lender to
approve modifications, consents, amendments or waivers thereof; and all such
actions or notices shall be deemed actions or notices of the Lender only when
duly provided in writing and given in accordance with the provisions of this
Agreement.

SECTION 10.03 NONLIABILITY OF THE LENDER.

         The relationship between Borrower and the Lender is, and shall at all
times remain, solely that of borrower and lender. The Lender neither undertakes
nor assumes any responsibility or duty to Borrower to review, inspect,
supervise, pass judgment upon or inform Borrower of any matter in connection
with any phase of Borrower's business, operations or condition, financial or
otherwise. Borrower shall rely entirely upon its own judgment with respect to
such matters, and any review, inspection, supervision, exercise of judgment or
information supplied to Borrower by the Lender, or any representative or agent
of the Lender, in connection with any such matter is for the protection of the
Lender, and neither Borrower nor any third party is entitled to rely thereon.

lender, and based upon such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement, and will
make such investigation as it deems necessary to inform itself as to the Loan,
the Loan Documents, the Subsidiary Documents, Borrower and any collateral;
PROVIDED, HOWEVER, nothing contained in this Section shall limit Agent's
obligation to provide the Lender with the information and documents Agent is
expressly required to deliver under this Agreement;

         (a)      Lender hereby designates and appoints Renaissance Group as
its Agent under this Agreement and authorizes the Agent to take such action on
its behalf under the provisions of this Agreement and the other Loan Documents
and the Subsidiary Documents and to exercise such powers as are set forth
herein or therein, together with such other powers as are reasonably
incidental thereto. In performing its functions and duties under this
Agreement, the Agent shall act solely as agent of the Lender and does not
assume, and shall not be deemed to have assumed, any obligation toward or
relationship of agency or trust with or for Borrower. The Agent may perform

the Subsidiary Documents, by or through its agents or employees.

         (b)      The Agent shall have no duties or responsibilities except
those expressly set forth in this Agreement, in the other Loan Documents or in
the Subsidiary Documents. Except as expressly provided herein, the duties of
the Agent shall be mechanical and administrative in nature. The Agent shall
have, and may use, its sole discretion with respect to exercising or
refraining from taking any actions which the Agent is expressly entitled to
take or assert under this Agreement, the other Loan Documents and the
Subsidiary Documents. The Agent shall not have, by reason of this Agreement, a
fiduciary relationship with respect to the Lender. Nothing in this Agreement,
any of the other Loan Documents or any of the Subsidiary Documents, express or
implied, is intended to or shall be construed to impose upon the Agent any
obligations in respect of this Agreement, any of the other Loan Documents or
any of the Subsidiary Documents except as expressly set forth herein or
therein. If the Agent seeks the consent or approval of the Lender to the
taking or refraining from taking any action hereunder, the Agent shall send
notice thereof to the Lender. The Agent may employ agents, co-agents and

agents, for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.

         (c)      Neither the Agent nor any of its officers, directors,
employees or agents shall be liable to the Lender for any action taken or
omitted by it or any of them under this Agreement, any of the other Loan
Documents or any of the Subsidiary Documents, or in connection herewith or
therewith, except that no Person shall be relieved of any liability imposed by
law, intentional tort or gross negligence. The Agent shall not be responsible
to the Lender for any recitals, statements, representations or warranties
contained in this Agreement or for the execution, effectiveness, genuineness,
validity, enforceability, collectability or sufficiency of this Agreement, any
of the other Loan Documents or any of the Subsidiary Documents or any of the
transactions contemplated thereby, or for the financial condition of Borrower
or the Subsidiaries. The Agent shall not be required to make any inquiry
concerning either the performance or observance of any of the terms,
provisions or conditions of this Agreement, any of the other Loan Documents or
any of the Subsidiary Documents or the financial condition of Borrower, or the
existence or possible existence of any Default or Event of Default. Agent
shall give the Lender notice of any Default or Event of Default of which Agent
has actual notice. The Agent may, at any time, request instructions from the
Lender with respect to any actions or approvals which, by the terms of this
Agreement, of any of the other Loan Documents or of any of the Subsidiary
Documents, the Agent is permitted or required to take or to grant, and if such
instructions are promptly requested, the Agent shall be absolutely entitled to
refrain from taking any action or to withhold any approval and shall not be
under any liability whatsoever to any Person for refraining from any action or
withholding any approval under any of the Loan Documents or any of the
Subsidiary Documents until it shall have received such instructions from the
Lender. Without limiting the foregoing, the Lender shall not have any right of
action whatsoever against the Agent as a result of the Agent acting or
refraining from acting under this Agreement, any of the other Loan Documents
or any of the Subsidiary Documents in accordance with the instructions of the
Lender.

         (d)      The Agent shall be entitled to rely upon any written
notices, statements, certificates, orders or other documents or any telephone
message believed by it, in good faith, to be genuine and correct and to have
been signed, sent or made by the proper Person, and with respect to all
matters pertaining to this Agreement, any of the other Loan Documents or any
of the Subsidiary Documents and its duties hereunder or thereunder, upon
advice of counsel selected by it.

         (e)      To the extent that the Agent is not reimbursed and
indemnified by Borrower, the Lender will reimburse and indemnify the Agent for
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses, advances or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement, any
of the other Loan Documents, or any of the Subsidiary Documents or any action
taken or omitted by the Agent under this Agreement, any of the other Loan
Documents or any of the Subsidiary Documents. The obligations of the Lender
under this indemnification provision shall survive the payment in full of the
Loans and the termination of this Agreement.

SECTION 12.01 STRICT COMPLIANCE.

         Any waiver by the Lender of any breach or any term or condition of this
Agreement, the other Loan Documents or the Subsidiary Documents shall not be
deemed a waiver of any other breach, nor shall any failure to enforce any
provision of this Agreement, the other Loan Documents or the Subsidiary
Documents operate as a waiver of such provision or of any other provision, nor
constitute nor be deemed a waiver or release of Borrower for anything arising
out of, connected with or based upon this Agreement, the other Loan Documents or
the Subsidiary Documents.

SECTION 12.02 WAIVERS AND MODIFICATIONS.

         All modifications, consents, amendments or waivers (herein "Waivers")
of any provision of this Agreement, the Debentures, any other Loan Documents or
any Subsidiary Documents, and any consent to departure therefrom, shall be
effective only if the same shall be in writing by the Lender and then shall be
effective only in the specific instance and for the purpose for which given. No
notice or demand given, in any case, shall constitute a waiver of the right to
take other action in the same, similar or other instances without such notice or
demand. No failure to exercise, and no delay in exercising, on the part of Agent
or Lender, any right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right. The rights of Lender hereunder,
under the other Loan Documents and under the Subsidiary Documents shall be in
addition to all other rights provided by law.

SECTION 12.03 LIMITATION ON LIABILITY.

         The duties, warranties, covenants and promises arising from the Loan
Documents and the Subsidiary Documents of Lender or Agent to Borrower shall be

action against Lender or Agent (or their successors or assigns) for any
liability of the other (or its successors or assigns).

SECTION 12.04 CHOICE OF FORUM; CONSENT TO SERVICE OF PROCESS AND JURISDICTION.

         Any suit, action or proceeding against Borrower with respect to this
Agreement or the Debentures or any judgment entered by any court in respect
thereof, may be brought in the courts of the State of Texas, County of Dallas,
or in the United States federal courts located in the State of Texas, as Lender
or Agent, in its sole discretion, may elect, and Borrower hereby submits to the
nonexclusive jurisdiction of such courts for the purpose of any such suit,
action or proceeding. Borrower hereby agrees that service of all writs, process
and summonses in any such suit, action or proceeding brought in the State of
Texas may be brought upon, and Borrower hereby irrevocably appoints, CT
Corporation System, Dallas, Texas, as its true and lawful attorney-in-fact in
the name, place and stead of Borrower to accept such service of any and all such
writs, process and summonses. Borrower hereby irrevocably waives any objections
which it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or any Debentures
brought in such courts, and hereby further irrevocably waives any claim that any
such suit, action or proceeding brought in any such court has been brought in
any inconvenient forum.

Agreement (Continued)
--------------------------------------------------------------------------------

SECTION 12.05 INVALID PROVISIONS.

         If any provision of any Loan Document is held to be illegal, invalid or
unenforceable under present or future laws during the term of this Agreement,
such provision shall be fully severable; such Loan Document shall be construed
and enforced as if such illegal, invalid or unenforceable provision had never
comprised a part of such Loan Document; and the remaining provisions of such
Loan Document shall remain in full force and effect and shall not be affected by
the illegal, invalid or unenforceable provision or by its severance from such
Loan Document. Furthermore, in lieu of each such illegal, invalid or
unenforceable provision shall be added as part of such Loan Document a provision
mutually agreeable to Borrower and Lender as similar in terms to such illegal,
invalid or unenforceable provision as may be possible and be legal, valid and
enforceable. In the event Borrower and Lender are unable to agree upon a
provision to be added to the Loan Document within a period of ten (10) business
days after a provision of the Loan Document is held to be illegal, invalid or
unenforceable, then a provision acceptable to independent arbitrators, such to
be selected in accordance with the provisions of the American Arbitration
Association, as similar in terms to the illegal, invalid or unenforceable
provision as is possible and be legal, valid and enforceable shall be added
automatically to such Loan Document. In either case, the effective date of the
added provision shall be the date upon which the prior provision was held to be
illegal, invalid or unenforceable.

SECTION 12.06 MAXIMUM INTEREST RATE.

         (a)      Regardless of any provision contained in any of the Loan
Documents, Lender shall never be entitled to receive, collect or apply as
interest on the Debentures any amount in excess of interest calculated at the
Maximum Rate, and, in the event that Lender ever receives, collects or applies
as interest any such excess, the amount which would be excessive interest
shall be deemed to be a partial prepayment of principal and treated hereunder
as such; and, if the principal amount of the Obligation is paid in full, any
remaining excess shall forthwith be paid to Borrower. In determining whether
or not the interest paid or payable under any specific contingency exceeds
interest calculated at the Maximum Rate, Borrower and Lender shall, to the
maximum extent permitted under applicable law, (i) characterize any
nonprincipal payment as an expense, fee or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof, and (iii)
amortize, pro rate, allocate and spread, in equal parts, the total amount of
interest throughout the entire contemplated term of the Debentures; provided
that, if the Debentures is paid and performed in full prior to the end of the
full contemplated term thereof, and if the interest received for the actual
period of existence thereof exceeds interest calculated at the Maximum Rate,
Lender shall refund to Borrower the amount of such excess or credit the amount
of such excess against the principal amount of the Debentures and, in such
event, Lender shall not be subject to any penalties provided by any laws for
contracting for, charging, taking, reserving or receiving interest in excess
of interest calculated at the Maximum Rate.

         (b)      "Maximum Rate" shall mean, on any day, the highest
nonusurious rate of interest permitted by applicable law on such day that, at
any time or from time to time, may be contracted for, taken, reserved, charged
or received on the Indebtedness evidenced by the Debentures under the laws
which are presently in effect of the United States of America and the laws of
any other jurisdiction which are or may be applicable to the holder of the
Debentures and such Indebtedness or, to the extent permitted by law, under
such applicable laws of the United States of America and the laws of any other
jurisdiction which are or may be applicable to the holder of the Debentures
and which may hereafter be in effect and which allow a higher maximum
nonusurious interest rate than applicable laws now allow.

Agreement (Continued)
--------------------------------------------------------------------------------

SECTION 12.07 PARTICIPATIONS AND ASSIGNMENTS OF THE DEBENTURES.

         (a)      Lender and the Agent shall have the right to enter into a
participation agreement with any other party or its Affiliates with respect to
the Debentures, or to sell all or any part of the Debentures, but any
participation or sale shall not affect the rights and duties of Lender or the
Agent hereunder vis-a-vis Borrower. In the event that all or any portion of
the Loan shall be at any time, assigned, transferred or conveyed to other
parties, any action, consent or waiver (except for compromise or extension of
maturity), to be given or taken by Lender or the Agent hereunder (herein
"Action"), shall be such action as taken by the holder of a majority in amount
of the Principal Amount of the Debentures then outstanding, as such holder are
recorded on the books of Borrower and represented by the Agent as described in
subsection (b) below.

         (b)      Assignment or sale of the Debentures shall be effective on
the books of Borrower only upon (i) endorsement of the Debentures, or part
thereof, to the proposed new holder, along with a current notation of the
amount of payments or installments received and net Principal Amount yet
unfunded or unpaid, and presentment of such Debentures to Borrower for issue
of a replacement Debentures, in the name of the new holder; and (ii) delivery
of an opinion of counsel, reasonably satisfactory to Borrower, that transfer
shall not require registration or qualification under applicable state or
federal securities laws.

         (c)      The Debentures may be sold, transferred or assigned only to
Affiliates of Lender or permitted transferees in multiples of $100,000.

SECTION 12.08 CONFIDENTIALITY.

         (a)      All financial reports or information that are furnished to
Lender or Holders, or their respective director designees or other
representatives, pursuant to this Agreement or pursuant to the Debentures, the
other Loan Documents or the Subsidiary Documents shall be treated as
confidential unless and to the extent that such information has been otherwise
disclosed by Borrower, but nothing herein contained shall limit or impair the
Lender's or Holders' right to disclose such reports to any appropriate
Governmental Authority, or to use such information to the extent pertinent to
an evaluation of the Obligation, or to enforce compliance with the terms and
conditions of this Agreement, or to take any lawful action which the Lender or
Holders deem necessary to protect their respective interests under this
Agreement.

         (b)      Lender and the Agent shall use their reasonable efforts to
protect and preserve the confidentiality of such information, except for such
disclosure as shall be required for compliance by Lender or its respective
director designees with SEC reporting requirements or any administrative or
judicial proceeding or otherwise as a matter of law. The provisions of Section
5.01 notwithstanding, Borrower may refuse to provide information as required
pursuant thereto to an assignee or successor in interest to Lender, unless and
until such assignee or successor shall have executed an agreement to maintain
the confidentiality of the information as provided herein.

SECTION 12.09 BINDING EFFECT.

         The Loan Documents shall be binding upon and inure to the benefit of
Borrower and Lender and their respective successors, assigns and legal
representatives; PROVIDED, HOWEVER, that Borrower may not, without the prior
written consent of Lender, assign any rights, powers, duties or obligations
thereunder.

lessee of any property owned by Borrower, or for debts or claims accruing to any
such persons against Borrower. Notwithstanding anything contained herein, in the
Debentures, in any other Loan Document or in any Subsidiary Document, no conduct
by any or all of the parties hereto, before or after signing this Agreement, any
other Loan Document nor any Subsidiary Document, shall be construed as creating
any right, claim or cause of action against Lender, or any of its respective
officers, directors, agents or employees, in favor of any materialman, supplier,
contractor, subcontractor, purchaser or lessee of any property owned by
Borrower, nor to any other person or entity other than Borrower.

                           --------------------------

         A complaint was filed on November 27, 2000 in the Superior Court of
Forsyth County, N.C., by Flextronics International USA, INC. as plaintiff
("Flextronics"), claiming that Digital Recorders, Inc. ("DRI"), owed the sum of
$56,650.92 plus interest. (Flextronics had purchased the trade receivables of a
former vendor of Digital Recorders, Inc. with whom there were several problems;
the components received from the vendor were not acceptable, and the amounts
claimed had been specifically disputed in correspondence between the plaintiff's
collection agency and DRI.) Despite the actual knowledge of the current address
of DRI, Flextronics attempted service of process on the registered agent at a
former address, and then served through the Secretary of State, who also
acknowledged that the address listed was no longer valid, because DRI had moved.
Flextronics presented an "Entry of Default and Judgment by Default by Clerk"
which was signed by an assistant clerk of court and filed on March 7, 2001. On
May 14, 2001, Digital Recorders, Inc. received its first notice of the suit, by
execution on the default judgment issued by Flextronics at to DRI's correct,
current address. On May 24, 2001, DRI served a motion to set aside the default
and default judgment demonstrating the questionable service of process, the
absence of actual notice, and the existence of meritorious defenses to the
asserted claim. A hearing has been set for June 25, 2001. The company expects
the judgment to be set aside at the hearing.

         redemption (the "Redemption Date").

              (b)  The Holder may exercise its right to require that the
         Company redeem this Debenture pursuant to Section 4(a) prior to
         maturity by giving notice thereof to the Company, which notice shall
         specify the terms of redemption (including the place at which the
         Holder may obtain payment), the total redemption payment and the
         Redemption Date, which Redemption Date shall be within thirty (30) days
         of the date of such notice.

         5.   OPTIONAL REDEMPTION BY COMPANY.

              (a)  On any interest payment date, and after receipt of
         irrevocable notice from the Borrower as provided for below, this
         Debenture is redeemable, in whole but not in part, at 101% of the
         Principal Amount, together with accrued and unpaid interest through the
         Redemption Date, by the Company, if all of the following conditions are
         satisfied: (i) the average closing bid price for the Common Stock for
         the 20 consecutive trading days prior to the date of notice exceeds an
         amount equal to three times the Conversion Price then in effect, and
         the Common Stock is listed or quoted on the National Market, the
         SmallCap, AMEX or NYSE; (ii) the average daily trading volume for the
         20 consecutive trading days prior to the date of the irrevocable notice
         shall be no less than 40,000 shares; (iii) the market price for the
         Common Stock at the time of notice reflects a price-to-earnings ratio
         of no greater than 25 times fully diluted earnings per share, excluding
         any

                                       2
<PAGE>

         extraordinary gains; and (iv) the shares of Common Stock issuable
         upon conversion of this Debenture shall have been fully registered
         under applicable securities laws, or the Borrower shall have furnished
         to the Holder an opinion of counsel that such shares of Common Stock
         may be publicly sold pursuant to an exemption from registration under
         applicable securities laws. The Company's right of redemption is
         subject to the Holder's prior right of conversion of the Debenture.

              (b)  If the Holder shall notify the Company in writing of its
         intent to sell the Debenture, this Debenture is redeemable at the
         Borrower's option, in whole but not in part, at 101% of the Principle
         Amount, together with accrued and unpaid interest through the
         Redemption Date, by the Company for a period of up to 30 days after the
         date of notice.

              (c)  The Company may exercise its right to redeem this
         Debenture pursuant to Sections 5(a) and (b) prior to maturity by giving
         notice thereof to the Holder of this Debenture as such name appears on
         the books of the Borrower, which notice shall specify the terms of
         redemption (including the place at which the Holder may obtain
         payment), the total redemption payment and the Redemption Date.

         6.   CONVERSION RIGHT.

              (a)  The Holder of this Debenture shall have the right, at
         Holder's option, at any time, to convert all, or, in multiples of
         $100,000, any part of this Debenture into such number of fully paid and
         nonassessable shares of Common Stock as provided herein. The Holder of
         this Debenture may exercise the conversion right by giving written
         notice (the "Conversion Notice") to Borrower of the exercise of such
         right and stating the name or names in which the stock certificate or
         stock certificates for the shares of Common Stock are to be issued and
         the address to which such certificates shall be delivered. The
         Conversion Notice shall be accompanied by the Debenture. The number of
         shares of Common Stock that shall be issuable upon conversion of the
         Debenture shall equal the outstanding Principal Amount of the Debenture
         divided by the Conversion Price (as defined below) and in effect on the
         date the Conversion Notice is given; provided, however, that in the
         event that this Debenture shall have been partially redeemed, shares of
         Common Stock shall be issued pro rata, rounded to the nearest whole
         share. Conversion shall be deemed to have been effected on the date the
         Conversion Notice is received (the "Conversion Date"). In the case of
         any Debenture called for redemption, the conversion rights will expire
         at the close of business on the Redemption Date. Within 20 business
         days after receipt of the Conversion Notice, Borrower shall issue and
         deliver by hand against a signed receipt therefor or by United States
         registered mail, return receipt requested, to the address designated in
         the Conversion Notice, a stock certificate or stock certificates of
         Borrower representing the number of shares of Common Stock to which
         Holder is entitled and a check or cash in payment of all interest
         accrued and unpaid on the Debenture up to and including the Conversion
         Date. The conversion rights will be governed by the following
         provisions:

                                       3
<PAGE>

              (b)  CONVERSION PRICE. On the issue date hereof and until such
         time as an adjustment shall occur, the Conversion Price shall be $2.00
         per share; provided, however, that the Conversion Price shall be
         subject to adjustment at the times and in accordance with the
         provisions set forth below.

                   (i)   ADJUSTMENT FOR ISSUANCE OF SHARES AT LESS THAN THE
              CONVERSION PRICE. If and whenever any Additional Common Stock
              shall be issued by Borrower (the "Stock Issue Date") for a
              consideration per share less than the Conversion Price, then in
              each such case the initial Conversion Price shall be reduced to
              a new Conversion Price in an amount equal to the price per
              share for the Additional Common Stock then issued, if issued in
              connection with a sale of shares, or the value of the Additional
              Common Stock then issued, as determined in accordance with
              generally accepted accounting principles, if issued other than
              for cash, and the number of shares issuable to Holder upon
              conversion shall be proportionately increased; and, in the case
              of Additional Common Stock issued without consideration, the
              initial Conversion Price shall be reduced in amount and the
              number of shares issued upon conversion shall be increased in
              an amount so as to maintain for the Holder the right to convert
              the Debenture into shares equal in amount to the same percentage
              interest in the Common Stock of the Company as existed for the
              Holder immediately preceding the Stock Issue Date.

                   (ii)  SALE OF SHARES. In case of the issuance of
              Additional Common Stock for a consideration part or all of
              which shall be cash, the amount of the cash consideration
              therefor shall be deemed to be the gross amount of the cash
              paid to Borrower for such shares, before deducting any
              underwriting compensation or discount in the sale, underwriting
              or purchase thereof by underwriters or dealers or others
              performing similar services or for any expenses incurred in
              connection therewith. In case of the issuance of any shares of
              Additional Common Stock for a consideration part or all of
              which shall be other than cash, the amount of the consideration
              therefor, other than cash, shall be deemed to be the then fair
              market value of the property received.

                   (iii) STOCK SPLITS, SUBDIVISIONS OR COMBINATIONS. In the
              event of a stock split or subdivision of shares of Common Stock
              into a greater number of shares, the Conversion Price shall be
              proportionately decreased, and in the event of a combination of
              shares of Common Stock into a smaller number of shares, the
              Conversion Price shall be proportionately increased, such
              increase or decrease, as the case may be, becoming effective at
              the record date.

                   (iv)  STOCK DIVIDENDS. Shares of Common Stock issued as a
              dividend or other distribution on any class of capital stock of
              Borrower shall be deemed to have been issued without
              consideration.

                   (v)   EXCEPTIONS. The term "Additional Common Stock"
              herein shall mean all shares of Common Stock or securities
              convertible or exercisable into shares of Common Stock
              hereafter issued by Borrower (including Common Stock

                                       4
<PAGE>

              held in the treasury of Borrower), except (A) Common Stock issued
              upon the conversion of any of the Debentures; (B) Common Stock
              issuable upon exercise of presently outstanding amounts or stock
              options; or (C) up to 300,000 shares of Common Stock issuable
              upon exercise of employee or director stock options to be granted
              in the future at less than the initial Conversion Price.

              (c)  ADJUSTMENT FOR MERGERS AND CONSOLIDATIONS. In the event of
         any consolidation or merger of the Company with or into, or the sale of
         all or substantially all of the properties and assets of the Company,
         to any person, and in connection therewith, consideration is payable to
         holders of Common Stock in cash, securities or other property, then as
         a condition of such consolidation, merger or sale, lawful provision
         shall be made, and duly executed documents evidencing the same shall be
         delivered to the Holder, so that the Holder shall have the right at any
         time prior to the maturity of this Debenture to purchase, at a total
         price equal to the Conversion Price immediately prior to such event,
         the kind and amount of cash, securities or other property receivable in
         connection with such consolidation, merger or sale, by a holder of the
         same number of shares of Common Stock as were convertible by the Holder
         immediately prior to such consolidation, merger or sale. In any such
         case, appropriate provisions shall be made with respect to the rights
         and interest of the Holder so that the provisions hereof shall
         thereafter be applicable with respect to any cash, securities or
         property deliverable upon exercise hereof. Notwithstanding the
         foregoing, (i) if the Company merges or consolidates with, or sells all
         or substantially all of its property and assets to, any other person,
         and consideration is payable to holders of Common Stock in exchange for
         their Common Stock in connection with such merger, consolidation or
         sale which consists solely of cash, or (ii) in the event of the
         dissolution, liquidation or winding up of the Company, then the Holder
         shall be entitled to receive distributions on the date of such event on
         the same basis with holders of Common Stock as if this Debenture had
         been converted immediately prior to such event, less the Conversion
         Price. Upon receipt of such payment, if any, the rights of the Holder
         shall terminate and cease and this Debenture shall expire. In case of
         any such merger, consolidation or sale of assets, the surviving or
         acquiring person and, in the event of any dissolution, liquidation or
         winding up of the Company, the Company shall promptly, after receipt of
         this surrendered Debenture, make payment by delivering a check in such
         amount as is appropriate (or, in the case of consideration other than
         cash, such other consideration as is appropriate) to such person as it
         may be directed in writing by the Holder surrendering this Debenture.

              (d)  DISTRIBUTIONS. In the event of distribution to all Common
         Stock holders of any securities, cash or properties or assets or other
         rights to purchase securities or assets, then, after such event, this
         debenture will also be convertible into the kind and amount of
         securities, cash and other property which the Holder would have been
         entitled to receive if the Holder owned the Common Stock issuable upon
         conversion of the Debenture immediately prior to the occurrence of such
         event.

              (e)  CAPITAL REORGANIZATION AND RECLASSIFICATION. In case of
         any capital reorganization or reclassification of the Common Stock of
         Borrower (other than a change in par value or as a result of a stock
         dividend, subdivision, split up or combination of

                                       5
<PAGE>

         shares), this Debenture shall be convertible into the kind and
         number of shares of stock or other securities or property of
         Borrower to which the Holder of the Debenture would have been
         entitled to receive if the Holder owned the Common Stock issuable
         upon conversion of the Debenture immediately prior to the occurrence
         of such event. The provisions of the immediately foregoing sentence
         shall similarly apply to successive reorganizations, reclassifications,
         consolidations, exchanges, leases, transfers or other dispositions
         or other share exchanges.

              (f)  NOTICE. In the event Borrower shall propose to take any
         action which shall result in an adjustment in the Conversion Price,
         Borrower shall give notice to the Holder of this Debenture, which
         notice shall specify the record date, if any, with respect to such
         action and the date on which such action is to take place. Such notice
         shall be given on or before the earlier of 10 days before the record
         date or the date which such action shall be taken. Such notice shall
         also set forth all facts (to the extent known) material to the effect
         of such action on the Conversion Price and the number, kind or class of
         shares or other securities or property which shall be deliverable or
         purchasable upon the occurrence of such action or deliverable upon
         conversion of this Debenture.

              (g)  CERTIFICATE. Following completion of an event which
         results in an adjustment to the Conversion Price, Borrower shall
         furnish to the Holder of this Debenture a statement, signed by the
         Chief Executive Officer and the Secretary of the Borrower, of the
         facts creating such adjustment and specifying the resultant adjusted
         Conversion Price then in effect, which statement shall constitute an
         amendment to this Debenture.

              (h)  In the event of an adjustment to the Conversion Price due
         to a sale of securities by the Borrower below the Conversion Price
         which would result in the holders of all debentures evidencing the Loan
         having the right to acquire more than 20% of the then outstanding
         shares of Common Stock, the Borrower agrees to hold a vote of the
         shareholders within 120 days to authorize such an adjustment. In the
         event the shareholders reject the authorization, the Holder shall have
         the right to cause the Company to redeem the Debenture in accordance
         with the provisions of Section 4.

         7.   ONE-TIME ADJUSTMENT TO CONVERSION PRICE.

              (a)  Notwithstanding the provisions of Section 6 hereof, if the
         Company does not achieve operating income of at least $2,438,000 in
         fiscal year 2001 and the market price of the Common Stock is below the
         conversion price at the time of publication of the Company's results
         for that period, then the Conversion Price shall be automatically
         adjusted downward to an amount equal to volume-weighted average closing
         bid price of the Common Stock, as reported in THE WALL STREET JOURNAL,
         for the ten consecutive trading days (the "Trading Period") following
         Borrower's public press release of its fiscal year 2001 financial
         results; provided that the Conversion Price as adjusted shall not be
         less than $1.50 per share. If an adjustment occurs pursuant to this
         Section 7, then the Borrower shall furnish to the holder of this
         Debenture a statement, within ten days of the occurrence thereof,
         signed by the Chief Financial Officer and the Secretary of Borrower,

                                       6
<PAGE>

         of the facts creating such adjustment and specifying the adjusted
         Conversion Price then in effect. The Holder shall not convert this
         Debenture or sell any shares of Common Stock during the Trading Period,
         as well as nine days prior to the commencement of the Trading Period.
         This restriction also extends to any short selling of the shares of
         Common Stock by the Holder or any affiliate.

              (b)  Under no circumstance will this adjustment to the
         Conversion Price cause the holders of all debentures evidencing the
         Loan to acquire greater than 20% of the Borrower's then outstanding
         shares of Common Stock. In the event that this adjustment to the
         Conversion Price allows the holders of all debentures evidencing the
         Loan to acquire greater than 20% of the Borrower's then outstanding
         shares of Common Stock, then the debenture holders will be entitled to
         decrease the Conversion Price, so that their potential and actual
         ownership is equal to twenty percent (20%) of the issued and
         outstanding Common Stock at the time this adjustment becomes effective.

         8.   RESERVATION OF SHARES. Borrower warrants and agrees that it
shall at all times reserve and keep available, free from preemptive rights,
sufficient authorized and unissued shares of Common Stock or treasury shares
of Common Stock necessary to effect conversion of this Debenture.

         9.   TAXES. The Company shall pay any documentary or other
transactional taxes attributable to the issuance or delivery of this
Debenture or the shares of Common Stock issued upon conversion by the Holder
(excluding any federal, state or local income taxes and any franchise taxes
or taxes imposed upon the Holder by the jurisdiction, or any political
subdivision thereof, under which such Holder is organized or is qualified to
do business).

         10.  DEFAULT.

              (a)  EVENT OF DEFAULT. An "Event of Default" shall exist if an
         "Event of Default" (as defined in the Loan Agreement) shall occur and
         be continuing.

              (b)  REMEDIES UPON EVENT OF DEFAULT. If an Event of Default
         shall have occurred and be continuing, then the Holder may exercise any
         one or more of the rights and remedies provided in the Loan Documents,
         as the Holder, in its sole discretion, may deem necessary or
         appropriate.

              (c)  REMEDIES NONEXCLUSIVE. Each right, power or remedy of the
         Holder hereof upon the occurrence of any Event of Default as provided
         for in this Debenture or now or hereafter existing at law or in equity
         or by statute shall be cumulative and concurrent and shall be in
         addition to every other right, power or remedy provided for in this
         Debenture or now or hereafter existing at law or in equity or by
         statute, and the exercise or beginning of the exercise by the Holder or
         transferee hereof of any one or more of such rights, powers or remedies
         shall not preclude the simultaneous or later exercise by the Holder of
         any or all such other rights, powers or remedies.

              (d)  EXPENSES. Upon the occurrence of a Default or an Event of
         Default, which occurrence is not cured within the notice provisions, if
         any provided therefore, Borrower

                                       7
<PAGE>

         agrees to pay and shall pay all reasonable costs and expenses
         (including attorneys' fees and expenses) incurred by the Holder in
         connection with the preservation and enforcement of Holder's rights
         under the Convertible Loan Agreement, the Debenture, or any other
         Loan Document.

         11.  FAILURE TO ACT AND WAIVER. No failure or delay by the Holder
hereof to require the performance of any term or terms of this Debenture or
not to exercise any right or any remedy shall constitute a waiver of any such
term or of any right or of any default, nor shall such delay or failure
preclude the Holder hereof from exercising any such right, power or remedy at
any later time or times. By accepting payment after the due date of any
amount payable under this Debenture, the Holder hereof shall not be deemed to
waive the right either to require payment when due of all other amounts
payable, or to later declare a default for failure to effect such payment of
any such other amount. The failure of the Holder of this Debenture to give
notice of any failure or breach of the Borrower under this Debenture shall
not constitute a waiver of any right or remedy in respect of such continuing
failure or breach or any subsequent failure or breach.

         12.  CONSENT TO JURISDICTION. The Company hereby agrees and consents
that any action, suit or proceeding arising out of this Debenture may be brought
in any state or federal court in the State of Texas, including the United States
District Court for the Northern District of Texas, or in any other court having
jurisdiction over the subject matter, all at the sole election of the Holder
hereof, and by the issuance and execution of this Debenture, the Borrower
irrevocably consents to the jurisdiction of each such court. The Company hereby
irrevocably appoints CT Corporation System, Dallas, Texas, as agent for the
Borrower to accept service of process for and on behalf of the Borrower in any
action, suit or proceeding arising out of this Debenture. Except for default in
payment of interest or principal when and as they become due, and except as
otherwise specifically set forth herein or otherwise agreed to in writing by the
parties, any action, dispute, claim or controversy (all such herein called
"Dispute") between or among the parties as to the facts or the interpretation of
the Debenture shall be resolved by arbitration as set forth in the Loan
Agreement.

         13.  HOLDER'S RIGHT TO REQUEST MULTIPLE DEBENTURES. The Holder shall,
upon written request and presentation of the Debenture, have the right, at any
interest payment date, to request division of this Debenture into two or more
instruments, each of such to be in such amounts as shall be requested; provided
however, that no Debenture shall be issued in denominations of face amount less
than $100,000.

         14.  TRANSFER. Subject to Section 12.08 of the Loan Agreement, this
Debenture may be transferred on the books of the Borrower by the registered
Holder hereof, or by Holder's attorney duly authorized in writing, in multiples
of $100,000 only upon (i) delivery to the Borrower of a duly executed assignment
of the Debenture, or part thereof, to the proposed new Holder, along with a
current notation of the amount of payments received and net Principal Amount yet
unfunded, and presentment of such Debenture to the Borrower for issue of a
replacement Debenture, or Debentures, in the name of the new Holder, (ii) the
designation by the new Holder of the Lender's agent for notice, such agent to be
the sole party to whom Borrower shall be required to provide notice when notice
to Holder is required hereunder and who shall be the sole

                                       8
<PAGE>

party authorized to represent Lender in regard to modification or waivers
under the Debenture, the Loan Agreement, or other Loan Documents; and any
action, consent or waiver (other than a compromise of principal and interest)
when given or taken by Lender's agent for notice, shall be deemed to be the
action of the holders of a majority in amount of the Principal Amount of the
Debenture, as such holders are recorded on the books of the Borrower, and
(iii) in compliance with the legend to read as follows:

         "This Debenture has not been registered under the Securities Act of
         1933, as amended ("Act"), or applicable state securities laws ("State
         Acts"), and shall not be sold, hypothecated, or otherwise transferred,
         unless such transfer is made in compliance with the Act and the State
         Acts."

         The Company shall be entitled to treat any holder of record of the
Debenture as the Holder in fact thereof and of the Debenture and shall not be
bound to recognize any equitable or other claim to or interest in this Debenture
in the name of any other person, whether or not it shall have express or other
notice thereof, except as otherwise provided by applicable law.

         15.  NOTICES. All notices and communications under this Debenture
shall be in writing and shall be either delivered in person or by overnight
service, such as FedEx, and accompanied by a signed receipt therefor; or
mailed first-class United States certified mail, return receipt requested,
postage prepaid, and addressed as follows: (i) if to the Borrower at its
address for notice as stated in the Loan Agreement; and (ii) if to the Holder
of this Debenture, to the address (a) of such Holder as it appears on the
books of the Borrower or (b) in the case of a partial assignment to one or
more Holders, to the Lender's agent for notice, as the case may be. Any
notice of communication shall be deemed given and received as of the date of
such delivery if delivered; or if mailed, then three days after the date of
mailing.

         16.  MAXIMUM INTEREST RATE.

              (a)  Regardless of any provision contained in this Debenture,
         Lender shall never be entitled to receive, collect or apply as interest
         on the Debenture any amount in excess of interest calculated at the
         Maximum Rate, and, in the event that Lender ever receives, collects or
         applies as interest any such excess, the amount which would be
         excessive interest shall be deemed to be a partial prepayment of
         principal and treated hereunder as such; and, if the principal amount
         of the Debenture is paid in full, any remaining excess shall forthwith
         be paid to Borrower. In determining whether or not the interest paid or
         payable under any specific contingency exceeds interest calculated at
         the Maximum Rate, Borrower and Lender shall, to the maximum extent
         permitted under applicable law, (i) characterize any non principal
         payment as an expense, fee or premium rather than as interest, (ii)
         exclude voluntary prepayments and the effects thereof, and (iii)
         amortize, pro rate, allocate and spread, in equal parts, the total
         amount of interest throughout the entire contemplated term of the
         Debenture; provided that, if the Debenture is paid and performed in
         full prior to the end of the full contemplated term thereof, and if the
         interest received for the actual period of existence thereof exceeds
         interest calculated at the Maximum Rate, Lender shall refund to
         Borrower the amount of such excess or credit the amount of such excess
         against the principal amount of the Debenture and, in

                                       9

         such event, Lender shall not be subject to any penalties provided by
         any laws for contracting for, charging, taking, reserving or receiving
         interest in excess of interest calculated at the Maximum Rate.

              (b)  "Maximum Rate" shall mean, on any day, the highest
         nonusurious rate of interest (if any) permitted by applicable law on
         such day that, at any time or from time to time, may be contracted for,
         taken, reserved, charged or received on the Indebtedness evidenced by
         the Debenture under the laws which are presently in effect of the
         United States of America or by the laws of any other jurisdiction which
         are or may be applicable to the Holders of the Debenture and such
         Indebtedness or, to the extent permitted by law, under such applicable
         laws of the United States of America or by the laws of any other
         jurisdiction which are or may be applicable to the Holder of the
         Debenture and which may hereafter be in effect and which allow a higher
         maximum nonusurious interest rate than applicable laws now allow.

         17.  LOAN AGREEMENT, GUARANTY AND SECURITY AND PLEDGE AGREEMENTS. This
Debenture is issued pursuant to the Convertible Loan Agreement dated of even
date herewith among the Company and the other parties thereto, and the Holder is
entitled to all the rights and benefits thereunder. Both Borrower and the Holder

Company's subsidiaries pursuant to their Guaranty dated of even date herewith.

         18.  DEFINED TERMS. Capitalized terms used but not defined herein shall
have the meaning given them in the Loan Agreement.

         19.  GOVERNING LAW. This Debenture shall be governed by and construed
