Adverse Effect, and has the corporate power and authority to own its properties

<PAGE>   21

SECTION 4.03. NO CONFLICTS OR CONSENTS.

      Except as disclosed on Schedule 4.03, neither the execution and delivery
of the Loan Documents, nor the consummation of any of the transactions therein
contemplated, nor compliance with the terms and provisions thereof, will
contravene or materially conflict with any judgment, license, order or permit
applicable to Borrower, or any indenture, loan agreement, mortgage, deed of
trust, or other agreement or instrument to which Borrower is a party or by which
Borrower is or becomes bound, or to which Borrower is or becomes subject, or
violate any provision of the charter or bylaws of Borrower or trigger any
preemptive rights or rights of first refusal of any third party, in each case,
the failure of which to so comply with would not have a Material Adverse Effect
on Borrower or any of the transactions contemplated by any Loan Document. No
consent, approval, authorization or order of any court or governmental authority
or third party is required in connection with the execution and delivery by
Borrower of the Loan Documents or to consummate the transactions contemplated
hereby or thereby except those that have been obtained.

SECTION 4.04. ENFORCEABLE OBLIGATIONS.

      The Loan Documents have been duly executed and delivered by Borrower and
are the legal, valid and binding obligations of Borrower, enforceable in
accordance with their respective terms except as limited by bankruptcy,
insolvency or other laws of general application relating to or affecting the
enforcement of creditors' rights generally and general principals of equity.

SECTION 4.05. NO LIENS.

      Except for Permitted Liens, all of the properties and assets owned or

unaudited balance sheet of Borrower as of December 31, 1999 and the related
unaudited statement of income, stockholders' equity and statement of cash flow
for the twelve (12) months then ended. Such financial statements fairly present

<PAGE>   22

and have been prepared in accordance with GAAP (except that unaudited financial
statements omit certain footnotes); and as of the date hereof, there are no
obligations, liabilities or Indebtedness (including contingent and indirect
liabilities and obligations) of Borrower which are (separately or in the
aggregate) material and are not reflected in such financial statements or
otherwise disclosed herein or in the Schedules. Since the date of the
above-referenced year end financial statements and quarterly financial

under this Agreement.

SECTION 4.08. MATERIAL AGREEMENTS.

both, would constitute a default, under any contract, lease, loan agreement,
indenture, mortgage, security agreement, license agreement or other agreement or
obligation to which it is a party or by which any of its properties is subject
which could reasonably be expected to have a Material Adverse Effect, except as
described on Schedule 4.08. To the best knowledge of Borrower, it is not a party
to, or bound by, any contract or agreement, the faithful performance of which is
so onerous so as to create or to likely create a Material Adverse Effect on the
business, operations or financial condition of Borrower.


<PAGE>   23

best knowledge of Borrower, threatened, against Borrower, and there has been no
change in the status of any of the actions, suits, investigations, litigation or
proceedings disclosed to the Lenders which could reasonably be expected have a
Material Adverse Effect on Borrower or on any transactions contemplated by any
Loan Document. Borrower has not received any claim that Borrower currently
violates any federal, state or local law, ordinance, rule or regulation, which
could have an adverse effect on its business and, to the best of Borrower's

case, except where the same are being contested in good faith by appropriate
proceedings, as disclosed on Schedule 4.10.

      Except as disclosed on Schedule 4.10, Borrower has not received any notice
of deficiency or other adjustment from any taxing authority that is unresolved
as of the Loan Closing. No audit or examination, claim or proposed assessment by
any taxing authority is pending or, to the best knowledge of Borrower,
threatened against Borrower or any of its properties. All ad valorem and other
property taxes imposed on Borrower, or that may become a lien on Borrower's
assets and that are due and payable, have been paid in full. Borrower has
withheld or collected from each payment made to each of its U.S. employees the
amount of all taxes (including federal income taxes, Federal Insurance
Contributions Act taxes, and state and local income, payroll, and wage taxes,
among others) required to be withheld or collected.

      Schedule 4.14 lists (i) any "employee benefit plans" as described in the
Employee Retirement Income Security Act of 1974, as amended, and the rules and

pension plan not requiring any contribution by Borrower, paid time-off policy or
vacation/holiday/sick leave policy, and employee group life 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 engaged in a transaction

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 of the employee benefit plans
listed or required to be listed on Schedule 4.14 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
Lenders 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
Lenders 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

federal, state and local authorities necessary to conduct its business and own
and operate its assets (collectively, the "Permits") except such Permits, the
failure of which to so hold, would not have a Material Adverse Effect on
Borrower or any of the transactions contemplated by any Loan Document. Except as

Borrower has the right to use such intellectual property rights without
infringing or violating the rights of any third parties. No claim has been

challenging or questioning the validity or effectiveness of any such license or
agreement. Borrower is not in default of any such license agreements in any
material respect, and no event has occurred and is continuing which, with notice
or lapse of time or both, would constitute a material default. Each license
agreement is enforceable in accordance with its terms and has not been canceled,
abandoned or terminated, nor has Borrower received notice thereof. There are no
claims for trademark or copyright infringement pending or threatened against
Borrower or the Subsidiaries or their respective officers or directors. Neither

no other agreements, written or oral, between Borrower and any third parties
claiming an interest in Borrower's interest in the Scheduled Leases or otherwise
relating to Borrower's use and occupancy of any leased real property. All such
leases are valid and binding obligations of the parties thereto, are in full
force and effect and enforceable against the parties thereto in accordance with
their terms; and no event has occurred including, but not limited to, the
executed, delivery and performance of this Agreement and the consummation of the
transactions contemplated hereby which (whether with or without notice, lapse of
time or both) would constitute a default thereunder. No property leased under
any lease which the Lenders have 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 and normal conduct of

circumstances, conditions, events or incidents, including, without limitation,

properties, assets and business, now owned or hereafter acquired, against such
casualties, risks and contingencies, and in such types and amounts, as are
consistent with customary practices and standards of companies engaged in
similar businesses.


<PAGE>   37

SECTION 5.13. AUTHORIZATIONS AND APPROVALS.

      Borrower shall, and shall cause each of its Subsidiaries to, promptly
obtain, from time to time at its own expense, all such governmental licenses,
authorizations, consents, permits and approvals as may be required to enable it
to comply with its obligations hereunder and under the other Loan Documents.

SECTION 5.14. ERISA COMPLIANCE.

      Borrower shall (i) at all times, make prompt payment of all contributions
required under all Plans, if any, and shall meet the minimum funding standards
set forth in ERISA with respect to its Plans subject to ERISA, if any, (ii)
notify the Lenders immediately of any fact in connection with any of its Plans,
which might constitute grounds for termination thereof by the Pension Benefit
Guaranty Corporation or for the appointment by the appropriate United States
District Court of a trustee to administer such Plan, together with a statement,
if requested by the Lenders, as to the reason therefor and the action, if any,
proposed to be taken with respect thereto, and (iii) furnish to the Lenders,
upon their request, such additional information concerning any of its Plans as
may be reasonably requested.

SECTION 5.15. FURTHER ASSURANCES.

      Borrower shall, and shall cause each of its Subsidiaries to, make, execute
or endorse, and acknowledge and deliver or file or cause the same to be done,
all such notices, certifications and additional agreements, undertakings,
transfers, assignments, or other assurances, and take any and all such other
action, as the Lenders may, from time to time, deem reasonably necessary or
proper in connection with any of the Loan Documents, or the obligations of
Borrower or its Subsidiaries, if any, thereunder, which the Lenders may request
from time to time.

SECTION 5.16. INDEMNITY BY BORROWER.


<PAGE>   38

      Borrower shall indemnify, save, and hold harmless the Lenders and their
directors, officers, lenders, attorneys, and employees (singularly or
collectively, the "Indemnitee") from and against (i) any and all claims,
demands, actions or causes of action that 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 Lenders 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
Lenders with respect to any of the foregoing arising out of the gross negligence
or willful misconduct of the Lenders or their assignees or the breach by any
Lender or their assignees of this Agreement or any other Loan Document or other
document executed in connection with any of the aforesaid, the breach by the
Lenders or their 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 Lenders or their assignees, or from the transfer or
disposition by the Lenders of any Debenture or the Common Stock issued upon
conversion of the Debenture. 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


<PAGE>   39

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 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 by 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.

SECTION 5.17. RESERVATION OF SHARES.

      Borrower shall at all times reserve and keep available sufficient
authorized and unissued shares of Common Stock to effect the conversion of the
Debentures.

SECTION 5.18. OWNERSHIP OF SUBSIDIARIES.

      Borrower shall own at all times its current percentages of the capital
stock, or other equity interests in, of the Subsidiaries, except NWL
Laser-Technology GmbH.

SECTION 5.19. RETENTION OF STOCK OWNERSHIP.

      (a)   Borrower shall not offer, sell or otherwise dispose of any shares of
Common Stock or securities exercisable or convertible into shares of Common
Stock for a period of twelve (12) months following the Loan Closing without the
written approval of the Lenders, other than (i) Common Stock issued upon the
conversion of any of the Debentures; (ii) Common Stock issued upon exercise of
any presently outstanding employee stock options; and (iii) Common Stock issued
upon exercise of any presently outstanding warrants.

      (b)   Rudi Naumann and Eric M. Reuter will execute and deliver Lock-Up
Agreements at the Loan Closing which shall provide that they will not offer,
sell or otherwise dispose of the shares of Common Stock beneficially owned or
controlled by them (including subsequently acquired shares or securities
exercisable or convertible into shares), for a period of six (6) months
following the Loan Closing.

      (a)   Borrower will not increase the salary, bonus, or other compensation
programs (whether in cash, securities, or other property, and whether payment is

expended by any Lender or Agent in such performance or attempted performance to
any Lender or Agent at its principal office, together with interest thereon, at

                        ARTICLE IX - REGISTRATION RIGHTS

SECTION 9.01.  "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 plans or employee benefit plans or (ii) a
registration relating solely to an 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);

      (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


<PAGE>   47

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, 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 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;


<PAGE>   48

      (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)   The Holders will advise Borrower at the time a registration becomes
effective whether the Registrable Securities included in the registration will
be underwritten or sold directly by the Holders;

      (h)   If an underwriter requests a reasonable lock-up period of Borrower
and/or all sellers of Borrower's registered securities, the Holders will agree
to such lock-up, provided that this provision shall be limited to persons or
groups that hold ten percent (10%) or more of the Registrable Securities Then
Outstanding; and

      (i)   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 9.02.  SHELF REGISTRATION.

      Borrower shall file a "shelf" registration statement 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.


<PAGE>   49

SECTION 9.03.  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, and keep such registration statement
effective until the sooner of all such Registrable Securities having been
distributed, or until 120 days have elapsed since such registration statement
became effective (subject to 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


<PAGE>   50

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 9.04.  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 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 9.05.  EXPENSES OF REGISTRATION.

      All expenses, other than underwriting discounts and commissions applicable
to the Registrable Securities sold by selling Holders,


<PAGE>   51

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 reasonable
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 9.06.  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, underwriter or
controlling person, or (ii) for amounts paid in settlement of any such 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


<PAGE>   52

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, 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. 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 of 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


<PAGE>   53

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 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 9.07.  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


<PAGE>   54

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; 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 9.08.  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 said transferee or assignee is a transferee or
assignee of at least ten percent (10%) of the Registrable Securities and
provided that 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 provided, further, that 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


<PAGE>   55

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 9.9.  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.

                         ARTICLE X - BOARD OF DIRECTORS

SECTION 10.01. BOARD REPRESENTATION OR ATTENDANCE BY OBSERVER.

      (a)   Borrower herewith agrees that Agent shall have the right from time
to time to designate a nominee to serve as a member of the Board of Directors of
Borrower. In the event of a monetary Default under Section 8.01 hereof, the
Agent shall have the right to designate


<PAGE>   56

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 costs and expenses incurred in connection therewith
by any such designated Director or observer, or by Agent on behalf of such
Director of 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 LENDERS.

      The relationship between Borrower and the Lenders is, and shall at all
times remain, solely that of borrower and lender. The Lenders neither undertake
nor assume 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 Lenders, or any representative or agent of the
Lenders, in connection with any such matter is for the protection of the
Lenders, and neither Borrower nor any third party is entitled to rely thereon.

                 ARTICLE XI - AGENCY AND INTER-LENDER PROVISIONS

SECTION 11.01. THE LENDERS' REPRESENTATIONS AND WARRANTIES TO OTHER LENDERS.

      Each Lender represents and warrants to the other Lenders and the Agent:

      (a)   It is legal for it to make its portion of the Loan, and the making
of such portion of the Loan complies with laws applicable to it;

      (b)   It has made, without reliance upon any other Lenders, its own
independent review (including any desired investigations and inspections) of,
and it accepts and approves, the Loan, this Agreement and the associated
documents and all other matters and information which it deems pertinent. It
acknowledges that the Loan Documents and the Subsidiary Documents are a complete
statement of all understandings and respective rights and obligations between
and among the Lenders, Subsidiaries and Borrowers regarding the Loan;

      (c)   None of the Lenders have made any express or implied representation
or warranty to any other Lender with respect to this transaction;

      (d)   It will, independently and without reliance upon any other 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 other Lenders with the information and documents Agent is expressly
required to deliver under this Agreement;

      (e)   The relationship of each Lender is, and shall at all times remain,
solely that of each Lender of its respective Loan. The Lenders are not partners
or joint venturers in connection with the Loan; and

      (f)   The Loan Documents executed by the Lenders are valid and binding
obligations of the Lenders.

SECTION 11.02. WAIVER OF LOAN PROVISIONS OR INTEREST OR PRINCIPAL PAYMENTS.


<PAGE>   58

      A waiver of an interest or principal payment, a declaration of a Default
or any amendment, modification or waiver of this Agreement or the Debentures
will require the consent of the Lenders.

SECTION 11.03. AGENCY.

      (a)   Each of the Lenders 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 reasonable
incidental thereto. In performing its functions and duties under this Agreement,
the Agent shall act solely as agent of the Lenders 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 any of its duties under this
Agreement, or under the other Loan Documents or 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 Lenders. 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 Lenders to the taking or refraining from taking any action
hereunder, the Agent shall send notice thereof to the Lenders. The Agent may
employ agents, co-agents and attorneys-in-fact and shall not be responsible to
the Lenders or Borrower, except as to money or securities received by it or its
authorized 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 Lenders 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 not be responsible to the Lenders for
any recitals, statements, representations or warranties contained


<PAGE>   59

in this Agreement or for the execution, effectiveness, genuineness, validity,
enforceability, collectibility, 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 any of
Borrowers. 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 Lenders
notice of any Default or Event of Default of which Agent has actual notice. The
Agent may at any time request instructions from the Lenders 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 Lenders. Without limiting the foregoing, the
Lenders 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 Lenders.

      (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 Lenders 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 Lenders under this
indemnification provision shall survive the payment in full of the Loans and the
termination of this Agreement.

                           ARTICLE XII - MISCELLANEOUS

SECTION 12.01. STRICT COMPLIANCE.

      Any waiver by the Lenders of any breach or any term or condition of this
Agreement, the other Loan Documents shall not be deemed a waiver of any other
breach, nor shall any failure to enforce any provision of this Agreement or the
other Loan 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 or the
other Loan Documents.

SECTION 12.02. WAIVERS AND MODIFICATIONS.

      All modifications, consents, amendments or waivers (herein "Waivers") of
any provision of this Agreement, the Debentures or any other Loan Documents, and
any consent to departure therefrom, shall be effective only if the same shall be
in writing by the Lenders 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 any 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 any other right. The rights of any Lender hereunder or under the other
Loan 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 each Lender to Borrower shall be
several and not joint, and Borrower shall have no legal or equitable cause of
action against any Lender (or its successors or assigns) for any liability of
any other Lender (or its successors or assigns).


<PAGE>   61

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 each
Lender 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 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 Debenture 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.

SECTION 12.05. ARBITRATION.

      (a)   Upon the demand of the Lenders or Borrower (collectively the
"parties"), made before the institution of any judicial proceeding or not more
than 60 days after service of a complaint, third party complaint, cross-claim or
counterclaim or any answer thereto or any amendment to any of the above, any
Dispute (as defined below) shall be resolved by binding arbitration in
accordance with the terms of this arbitration clause. A "Dispute" shall include
any action, dispute, claim, or controversy of any kind, whether founded in
contract, tort, statutory or common law, equity, or otherwise, now existing or
hereafter occurring between the parties arising out of, pertaining to or in
connection with this Agreement, any document evidencing, creating, governing, or
securing any indebtedness guaranteed pursuant to the terms hereof, or any
related agreements, documents, or instruments (the "Documents"). The parties
understand that by this Agreement they have decided that the Disputes may be
submitted to arbitration rather that being decided through litigation in court
before a judge or jury and that once decided by an arbitrator the claims
involved cannot later be brought, filed, or pursued in court. IF BORROWER SHALL

TO PAY) NOT LATER THAN FIVE (5) DAYS AFTER THE DUE DATE, ANY INSTALLMENT OF
INTEREST ON OR PRINCIPAL OF, ANY DEBENTURE OR ANY FEE, EXPENSE OR OTHER PAYMENT

      (b)   Arbitrations conducted pursuant to this Agreement, including
selection of arbitrators, shall be administered by the American Arbitration
Association ("Administrator") pursuant to the Commercial Arbitration Rules of
the Administrator. Arbitrations conducted pursuant to the terms hereof shall be
governed by the provisions of the Federal Arbitration Act (Title 9 of the United
States Code), and


<PAGE>   62

to the extent the foregoing are inapplicable, unenforceable or invalid, the laws
of the State of Texas. Judgment upon any award rendered hereunder may be entered
in any court having jurisdiction; provided, however, that nothing contained
herein shall be deemed to be a waiver by any party that is a bank of the
protections afforded to it under 12 U.S.C. 91 or similar governing state law.
Any party who fails to submit to binding arbitration following a lawful demand
by the opposing party shall bear all costs and expenses, including reasonable
attorneys' fees, incurred by the opposing party in compelling arbitration of any
Dispute.

      (c)   No provision of, nor the exercise of any rights under, this
arbitration clause shall limit the right of any party to (i) foreclose against
any real or personal property collateral or other security, (ii) exercise
self-help remedies (including repossession and set off rights) or (iii) obtain
provisional or ancillary remedies such as injunctive relief, sequestration,
attachment, replevin, garnishment, or the appointment of a receiver from a court
having jurisdiction. Such rights can be exercised at any time except to the
extent such action is contrary to a final award or decision in any arbitration
proceeding. The institution and maintenance of an action as described above
shall not constitute a waiver of the right of any party, including the
plaintiff, to submit the Dispute to arbitration, nor render inapplicable the
compulsory arbitration provisions hereof. Any claim or Dispute related to
exercise of any self-help, auxiliary or other exercise of rights under this
section shall be a Dispute hereunder.

      (d)   Arbitrator(s) shall resolve all Disputes in accordance with the
applicable substantive law of the State of Texas. Arbitrator(s) may make an
award of attorneys' fees and expenses if permitted by law or the agreement of
the parties. All statutes of limitation applicable to any Dispute shall apply to
any proceeding in accordance with this arbitration clause. Any arbitrator
selected to act as the only arbitrator in a Dispute shall be required to be a
practicing attorney with not less than five (5) years practice in commercial law
in the State of Texas. With respect to a Dispute in which the claims or amounts
in controversy do not exceed five hundred thousand dollars ($500,000), a single
arbitrator shall be chosen and shall resolve the Dispute. In such case the
arbitrator shall have authority to render an award up to but not to exceed five
hundred thousand dollars ($500,000), including all damages of any kind
whatsoever, costs, fees and expenses. Submission to a single arbitrator shall be
a waiver of all parties' claims to recover more than five hundred thousand
dollars ($500,000). A Dispute involving claims or amounts in controversy
exceeding five hundred thousand dollars ($500,000) shall be decided by a
majority vote of a panel of three arbitrators ("Arbitration Panel"), one of whom
must possess the qualifications to sit as a single arbitrator in a Dispute
decided by one arbitrator. If the arbitration is consolidated with one conducted
pursuant to the terms


<PAGE>   63

of a guaranty of the Indebtedness, then the Arbitration Panel shall be one which
meets the criteria set forth between the Lenders and Borrower. Arbitrator(s)
may, in the exercise of their discretion, at the written request of a party, (i)
consolidate in a single proceeding any multiple party claims that are
substantially identical and all claims arising out of a single loan or series of
loans, including claims by or against borrower(s), guarantors, sureties and/or
owners of collateral if different from Borrower, and (ii) administer multiple
arbitration claims as class actions in accordance with Rule 23 of the Federal
Rules of Civil Procedure. The arbitrator(s) shall be empowered to resolve any
dispute regarding the terms of this Agreement or any Dispute or any claim that
all or any part (including this provision) is void or voidable but shall have no
power to change or alter the terms of this Agreement. The award of the
arbitrator(s) shall be in writing and shall specify the factual and legal basis
for the award.

      (e)   To the maximum extent practicable, the Administrator, the
arbitrator(s) and the parties shall take any action reasonably necessary to
require that an arbitration proceeding hereunder be concluded within 180 days of
the filing of the Dispute with the Administrator. The arbitrator(s) shall be
empowered to impose sanctions for any party's failure to proceed within the
times established herein. Arbitration proceedings hereunder shall be conducted
in Texas at a location determined by the Administrator. In any such proceeding a
party shall state as a counterclaim any claim which arises out of the
transaction or occurrence or is in any way related to the Loan Documents which
does not require the presence of a third party which could not be joined as a
party in the proceeding, The provisions of this arbitration clause shall survive
any termination, amendment, or expiration of the Loan Documents and repayment in
full of sums owed to the Lenders by Borrower unless the parties otherwise
expressly agree in writing. Each party agrees to keep all Disputes and
arbitration proceedings strictly confidential, except for disclosures of
information required in the ordinary course of business of the parties or as
required by applicable law or regulation.

SECTION 12.06. 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


<PAGE>   64

Document a provision mutually agreeable to Borrower and the Lenders 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 the Lenders 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 12.07. MAXIMUM INTEREST RATE.

      (a)   Regardless of any provision contained in any of the Loan Documents,
the Lenders 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 any 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 the Lenders 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 are 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, the Lenders 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, the Lenders 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


<PAGE>   65

may be applicable to the holders 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.

SECTION 12.08. PARTICIPATIONS AND ASSIGNMENTS OF THE DEBENTURES.

      (a)   The Lenders 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 any such 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 any Lender or the Agent hereunder (herein
"Action"), shall be such action as taken by the holders of a majority in amount
of the Principal Amount of the Debentures then outstanding, as such holders 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 Debenture, 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 Debenture to Borrower for issue of a replacement Debenture,
or 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 the Lenders or permitted transferees in multiples of $100,000.

SECTION 12.09. CONFIDENTIALITY.

<PAGE>   66

      (a)   All financial reports or information that are furnished to the
Lenders 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
Lenders' 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 Lenders or
Holders deem necessary to protect their respective interests under this
Agreement.

      (b)   The Lenders 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 the Lenders or their
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 the Lenders, unless and until such assignee or successor shall have executed
an agreement to maintain the confidentiality of the information as provided
herein.

SECTION 12.10. BINDING EFFECT.

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

SECTION 12.11. NO THIRD PARTY BENEFICIARY.

      The parties do not intend the benefits of this Agreement to inure to any
third party, nor shall this Agreement be construed to make or render the Lenders
liable to any materialman, supplier, contractor, subcontractor, purchaser or
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 the Lenders, or any of their
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.


<PAGE>   67

SECTION 12.12. ENTIRETY.

      This Agreement and the Debentures, the other Loan Documents, the
Subsidiary Documents and any other documents or instruments issued or entered
into pursuant hereto and thereto contain the entire agreement between the
parties and supersede all prior agreements and understandings, written or oral
(if any), relating to the subject matter hereof and thereof.

SECTION 12.13. HEADINGS.

      Section headings are for convenience of reference only and, except as a
means of identification of reference, shall in no way affect the interpretation
of this Agreement.

SECTION 12.14. SURVIVAL.

      All representations and warranties made by Borrower herein shall survive
delivery of the Debentures and the making of the Loans.

SECTION 12.15. MULTIPLE COUNTERPARTS.

      This Agreement may be executed in any number of counterparts, all of which
taken together shall constitute one and the same agreement, and any of the
parties hereto may execute this Agreement by signing any such counterpart.

SECTION 12.16. KNOWLEDGE OF BORROWER.

      As used herein or in any of the other Loan Documents, all references "to
Borrower's best knowledge" or "to the knowledge of Borrower" or words or phrases
of similar import (whether or not modified by any additional phrase) shall in
each case mean the knowledge of Borrower, the Subsidiaries or their respective
executive officers, directors and principal shareholders.

SECTION 12.17. NOTICES.

      (a)   Any notices or other communications required or permitted to be
given by this Agreement or any other documents and instruments referred to
herein must be (i) given in writing and personally delivered, mailed by prepaid
certified or registered mail or sent by overnight service, such as FedEx, or

                                FINANCIAL RATIOS


Borrower shall maintain the following financial covenants in accordance with the
definitions set forth below:

1.    DEBT TO TOTAL EQUITY. The ratio of total liabilities to total equity which
      shall not exceed 2.00 to 1.00 during each quarter prior to the sale of NWL
      Laser-Technology GmbH and 1.50 to 1.00 during each quarter thereafter.

2.    CURRENT RATIO. Maintain at all times a current ratio ("current ratio"
      being defined as the quotient of current assets divided by current
      liabilities) of 1.00 to 1.00.

3.    INTEREST COVERAGE. "Interest coverage" is defined as a fraction in which
      the numerator is the sum of the trailing twelve (12) months' net income
      before taxes, interest and depreciation and the denominator is the
      trailing twelve (12) months' interest expense. Interest coverage must not
      be less than 1.50 to 1.00.
