ITEM 5.   OTHER EVENTS

MERGER FINANCING.  
- ----------------                                                       

On March 2, 1998, La-Man Corporation (the "Company") consummated a series of
transactions with Renaissance Capital Growth & Income Fund III, Inc., a Texas
corporation, and Renaissance US Growth & Income Trust PLC, a public limited
company registered in England and Wales (individually, "Lender" and,
collectively, "Lenders"), that yielded gross proceeds to the Company of
$4,500,000. The transactions with the Lenders were as follows:

     1.   Convertible Loan Agreement.  
          --------------------------                                 

          Pursuant to a Convertible Loan Agreement between the Company and the
          Lenders dated as of March 2, 1998 ("Convertible Loan Agreement"), each
          of the Lenders purchased from the Company $1,750,000 principal amount
          of the Company's 8.75% Convertible Debentures Due March 2, 2005
          ("Debentures"). If not sooner redeemed or converted, the Company is
          required to pay to the holders of the Debentures, commencing March 2,
          2001 and continuing on the first day of each successive month
          thereafter prior to maturity, mandatory principal redemption
          installments in the amount of $10.00 per $1,000 of the then remaining
          principal amount of the Debentures. The Debentures are redeemable at
          the option of the holders under certain conditions, such as a change
          in control of the Company's voting stock, or delisting of the
          Company's common stock. The Debentures are also redeemable at the
          option of the Company on any interest payment date at 101% of par
          together with accrued and unpaid interest if the Company's common
          stock maintains a certain average trading price for a period prior to
          the delivery of the redemption notice and the average daily trading
          volume of the Company's common stock maintains a specified average for
          a period prior to the redemption notice. Holders of the Debentures
          have the right at any time to convert all, or multiples of $100,000,
          of the Debentures into common stock of the Company at an initial
          conversion price of $4.75 per share, subject to adjustment as provided
          by the terms of the Debentures. The Convertible Loan Agreement
          provides holders of the Debentures both demand and piggyback
          registration rights with respect to the shares of common stock
          issuable upon conversion of the Debentures, and also obligates the
          Company to file a shelf registration statement covering such shares
          not later than March 2, 1999. The Convertible Loan Agreement also
          contains certain covenants requiring the Company to maintain various
          financial ratios on a quarterly basis. Copies of the Convertible Loan
          Agreement and the Debentures are filed with this Report as Exhibits
                                                                     --------
          10.1, 10.2 and 10.3, respectively.
          -------------------

     2.   Sale of Common Stock.  
          --------------------                                            

          On March 2, 1998, the Company also issued and sold to each of the
          Lenders 115,741 shares of the Company's common stock in a private
          offering for total gross proceeds to the Company of $1,000,000.

     3.   Common Stock Purchase Warrants.  
          ------------------------------                                  

          As additional consideration for the Lenders' purchase of the
          Debentures and common stock, the Company granted each of the Lenders a
          warrant to purchase 100,000 shares of the Company's common stock at
          the exercise price of $4.32 per share, in whole or in part at any time
          through March 2, 2003. The exercise price of the warrants is subject
          to customary anti-dilution adjustments. Copies of the Stock Purchase
          Warrants are filed with this Report as Exhibits 10.4 and 10.5,
                                                 ----------------------
          respectively.
                         

     4.   Lock-Up Agreements.  
          ------------------                                        

          As a condition to the purchase of the Debentures and the common stock,
          the Lenders also required that Messrs. J. Melvin Stewart, the Chairman
          of the Company's Board of Directors, and J. William Brandner, the
          Company's President and Chief Executive Officer, enter into agreements
          not to sell or otherwise dispose of any shares of the Company's common
          stock beneficially owned or controlled by them prior to March 2, 1999
          and, for the 12-month period thereafter, only to sell or dispose of
          such shares pursuant to SEC Rule 144. Copies of the respective Lock-Up
          Agreements are filed with this Report as Exhibits 10.6 and 10.7,
                                                   ----------------------
          respectively.


     The obligations of the Company under the Convertible Loan Agreement and the
Debentures are secured by a pledge to the Lenders of all of the outstanding
shares of capital stock of the Company's subsidiaries pursuant to a Pledge
Agreement dated as of March 2, 1998 between the Company and the Lenders, the
joint and several guarantees of each of the Company's subsidiaries, and security
interests in various tangible and intangible personal assets of the Company and
its subsidiaries. Copies of the Pledge Agreement, the Security Agreement between
the Company and the Lenders, the form of Continuing Guaranty of each of the
Company's subsidiaries, and the form of Security Agreement executed and
delivered by each of such subsidiaries to the Lenders, are filed with this
Report as Exhibits 10.8, 10.9, 10.10 and 10.11, respectively.
          ------------------------------------               

     On February 18, 1998, the Company acquired Electronic Sign Corporation, a
California corporation ("ESC"), pursuant to a merger of ESC into Ad Art
Displays, Inc., a wholly owned Florida subsidiary of the Company ("Ad Art"). The
proceeds from the transactions with the Lenders were used in part to retire ESC
indebtedness of $3 million to certain of its former shareholders and to provide
working capital to Ad Art.

AMENDMENTS TO LA-MAN CORPORATION STOCK OPTION AND APPRECIATION RIGHTS PLAN.
- -------------------------------------------------------------------------- 

     Effective August 29, 1997, the Company's Board of Directors adopted
Amendment No. 2 to the Company's 1992 Stock Option and Appreciation Rights Plan,
as amended (the "1992 Plan"). This amendment modified Section 2.5 of the 1992
Plan to increase from 2,000 to 10,000 the number of options granted annually to
non-employee directors and to change the time of grant of such options from June
of each year to the date as soon as practicable following each annual meeting of
the Company's shareholders.

                                       3
<PAGE>
 
     Also effective August 29, 1997, the Company's Board of Directors approved
Amendment No. 3 to the 1992 Plan. This amendment modified Section 6.4 of the
1992 Plan by requiring that Non-Qualified Options outstanding upon death of an
optionee must be exercised by optionee's heirs within six months following the
date of the optionee's death. Amendment No. 3 also modified Section 7.6 of the
1992 Plan by providing for exercise of options by surrendering such options and
receiving in exchange an amount equal to the difference between the then fair
market value of the shares of the Company's common stock issuable upon exercise
of the options surrendered and the option price payable upon exercise of the
option or portion thereof surrendered.

     Copies of Amendment No. 2 and Amendment No. 3 to the 1992 Plan are filed
with this Report as Exhibits 10.12 and 10.13, respectively.
                    ------------------------

AMENDMENT TO LA-MAN CORPORATION AMENDED AND RESTATED 1994 EMPLOYEE AND
- ----------------------------------------------------------------------
CONSULTANT STOCK COMPENSATION PLAN
- ----------------------------------

     Effective August 29, 1997, the Board of Directors of the Company adopted
Amendment No. 2 to the La-Man Corporation Amended and Restated 1994 Employee and
Consultant Stock Compensation Plan, as amended (the "1994 Plan"). This amendment
added certain procedures relative to exercise of options granted under the 1994
Plan, including provisions that permit optionees to surrender options in
exchange for a number of shares equal to the difference between the fair market
value of the shares issuable upon exercise of the options and the option price
payable upon the exercise of such options. The amendment also provides that in
the event the employment or service of an option holder by the Company
terminates as the result of disability, any outstanding options terminate on the
earlier of the applicable expiration date of such options or 12 months following
the date of such termination of employment or service. Also, any options held by
a person at the time of such person's death must be exercised by his heirs or
estate prior to the earlier of the applicable expiration date of such options or
six months following the date of death (or such shorter time as may be provided
in the applicable option agreement). A copy of Amendment No. 2 to the 1994 Plan
is filed with this Report as Exhibit 10.14.
                             -------------

The above summaries of the terms and provisions of the above-described documents
are qualified in their entirety by reference to the actual terms and provisions

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 involving any employee
benefit plan (other than routine non-contested claims for benefits).

the failure of which to obtain could reasonably be expected to have a Material
Adverse Effect.  Except as set forth on Schedule 4.15, neither Borrower nor any
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, which individually or in
the aggregate could have a Material Adverse Effect.  Except as set forth on
Schedule 4.15, Borrower and the Subsidiaries have not received any notice or
communication from any federal, state or local governmental or regulatory
authority or otherwise of any such violation or noncompliance, which
individually or in the aggregate could have a Material Adverse Effect.  To the
best of their knowledge, Borrower and the Subsidiaries have not engaged in any
practices in violation of any antitrust law or regulation of any federal, state
or local Governmental Authority.

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

such license agreements in any material respect, and no event has occurred and

terms and has not been canceled, abandoned or terminated, nor has Borrower
received notice thereof. There are no claims for trademark or copyright

respective officers or directors. Neither Borrower nor any Subsidiary is

     (b) Borrower has delivered to the Lenders true and correct copies of all of
its leases or subleases and all related amendments, supplements and
modifications and related documents (the "Scheduled Lease Documents"), which
require payments or contingent payments by Borrower of any of the Subsidiaries
subsequent to the date hereof in excess of $25,000.  There are 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
Borrower's business.

     (c) On the Loan Closing Date, Borrower will hold of record good, marketable
and insurable title to the property described in Schedule 4.27 free and clear of
all title defects, liens, pledges, claims, charges, rights of first refusal,
security interests or other encumbrances and not, in the case of the real
property, subject to any rights-of-way, building or use restrictions,
exceptions, variances, reservations or limitations of any nature whatsoever,
except with respect to all such properties, (i) matters set forth in Schedule
4.27, and (ii) liens for current taxes and assessments not in default
(collectively, the "Permitted Encumbrances").  Notwithstanding the foregoing,
Borrower's representations and warranties regarding title defects with respect
to the real property is limited to defects arising by, through or under
Borrower, but not otherwise.  Borrower and the Subsidiaries have adequate title
insurance coverage for such properties.  All real property and structures owned
or leased by Borrower, and all equipment owned or leased by Borrower, are in
good operating condition and repair (ordinary wear and tear excepted), taking
into account their respective ages and consistent with their past uses, and are
adequate for the uses to which they are being put.  Except as set forth on
Schedule 4.27, to Borrower's best knowledge, the buildings and improvements
owned or leased by Borrower are structurally sound.  Borrower has not received
any notice of any violation of any building,

structures or their use by Borrower. To Borrower's best knowledge, there is no
existing, proposed or contemplated plan to modify or realign any street or
highway or any existing, proposed or contemplated eminent domain proceeding that
would result in the taking of all or any part of the real property or that would
materially adversely affect the current or planned use of the real property or
any part thereof. The facilities consisting of owned personal property are
subject to no liens or encumbrances except the security interests of record set
forth on Schedule 4.27, which Schedule is a copy of a Uniform Commercial Code
("UCC") search duly obtained by Borrower in the last thirty (30) days and which
search shows security interests of record relating to such facilities in the
States of Florida, California and Nevada. Borrower agrees to remove all security
interests reflected on such UCC search, if any, prior to the Loan Closing
(except those approved by the Lenders in writing) and to remove any other
security interests filed with respect to such facilities between the date of
such UCC search and the date of the Loan Closing. Schedule 4.27 also describes
all construction work, if any, which Borrower has contracted for and which is
presently in progress in respect of the business, and also contains a good faith
estimate, as of the date of this Agreement, of the cost and timetable to
complete each such project. Copies of the architect's, and the contractor's, if
any, plans and specifications with respect to such construction in progress have
been delivered to the Lenders.

     (a) Borrower is currently in compliance with all Environmental Laws (as
defined below) which compliance includes, but is not limited to, the possession
by Borrower of all permits and other governmental authorization required under
applicable Environmental Laws, and compliance in all material respects with the
terms and conditions thereof, except in any case where the failure to be in
compliance would not have a Material Adverse Effect.

     (b) Except as set forth on Schedule 4.28, Borrower has not stored, disposed
of or arranged for disposal of any Materials of Environmental Concern (as
defined below) on any of the real property, except in compliance with applicable

     (c) Borrower has not received any communication (written or oral), whether
from a governmental authority, citizens group, employee or otherwise, that

there are no circumstances that may prevent or interfere with such full
compliance in the future.  There is no Environmental Claim (as defined below)
pending or, to Borrower's best knowledge, threatened against, or which has been
made known to, Borrower.

     (d) Except as set forth on Schedule 4.28, during the period the facilities
have been held by Borrower, its affiliates or, to Borrower's best knowledge, its
predecessors in interest, there have been no actions, activities, circumstances,
conditions, events or incidents, including, without limitation, the generation,
handling, transportation, treatment, storage, release, emission, discharge,
presence or disposal of any Hazardous Substance (as defined below), that could
form the basis of any Environmental Claim against Borrower under any
Environmental Law in effect at, or at any time prior to, the Loan Closing.

     (e) Without in any way limiting the generality of the foregoing, (i) there
are no underground storage tanks located on the property owned or leased by
Borrower or the Subsidiaries, (ii) there is no

collectively, the "Indemnitee") from and against (i) any and all claims,
demands, actions or causes of action that are asserted against any Indemnitee if

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

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 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.

     (a) Borrower hereby agrees to use its best efforts to register all or any
portion of the Registrable Securities on two occasions (but no more than one per
year) within 18 months after Loan Closing, 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 an 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

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

(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 senior to
those of any Persons 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) Notwithstanding the foregoing, Borrower may delay filing a registration
statement, and may withhold efforts to cause the registration statement to
become effective, for a period of not more than ninety (90) days if Borrower
determines in good faith that such registration might interfere with or affect
the negotiation or completion of any transaction involving Borrower.  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 registration
statements 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) Borrower shall have the right to exclude an underwriter not reasonably
acceptable to it.

     (f) No demand for registration may be made for a ninety (90)-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 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 

- --------------------------------------------------------------------------------
                                      35
<PAGE>
 
Agreement (Continued)
- --------------------------------------------------------------------------------

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 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;

     (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;

                                      36
<PAGE>
 
Agreement (Continued)
- --------------------------------------------------------------------------------

     (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 9.03.  SHELF REGISTRATION.
- ----------------------------------

     Borrower shall file a "shelf" registration statement under the 1933 Act
(the "Shelf Registration") covering all of the Registrable Securities within 360
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.  The holders of the Debentures shall utilize Rule 144 in their
sole discretion to the extent it meets their distribution requirements.
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, 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);

                                      37
<PAGE>
 
Agreement (Continued)
- --------------------------------------------------------------------------------

     (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 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

- --------------------------------------------------------------------------------
                                      38

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

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.
- ----------------------------------------

     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, 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 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 

- --------------------------------------------------------------------------------
                                      39
<PAGE>
 
Agreement (Continued)
- --------------------------------------------------------------------------------

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 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.

<PAGE>
 
Agreement (Continued)
- --------------------------------------------------------------------------------

     (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; 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 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 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.

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

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 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, information, correspondence and communications sent by
Borrower to members of the Board of Directors.  All costs and expenses incurred

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

States Code), and 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

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

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.

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

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

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.

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

        (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

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 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

                                       49

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

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 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

applicable laws now allow.

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

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.

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.

Affiliates of the Lenders or permitted transferees in multiples of $100,000.

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

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

any materialman, supplier, contractor, subcontractor, purchaser or lessee of any
property owned by Borrower, nor to any other person or entity other than

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 face 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:

     (b) Conversion Price.  On the issue date hereof and until such time as an
         -----------------                                                    
adjustment shall occur, the Conversion Price shall be $4.75 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.  Any such adjustment
shall be subject to the Company's optional right to redeem this Debenture as set
forth in Section 5(b) hereof, upon notice given in the manner set forth in
Section 5(c) hereof.

               (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 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.

               (iv)  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.

               (v)   Exceptions. The term "Additional Common Stock" herein shall
                     ----------
mean all shares of Common Stock hereafter issued by Borrower (including Common
Stock held in the treasury of Borrower), except (A) Common Stock issued upon the
conversion of any of the Debentures; (B) Common Stock issued upon exercise of
any outstanding

warrants, options or convertible debt instruments; (C) Common Stock issued upon
exercise of outstanding employee stock options; (D) up to 200,000 shares of
Common Stock issuable upon exercise of warrants issued to the Holders; and (E)
up to 200,000 shares of Common Stock to be issued upon exercise of options or
warrants to be granted to its investment advisors for consulting services or to
employees under its employee stock option and stock compensation plans.

     (c) Adjustment for Mergers, Sales 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 exercisable 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 an equal 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 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.

     7.  ONE-TIME ADJUSTMENT TO CONVERSION PRICE.  Notwithstanding the
         ---------------------------------------                      
provisions of Section 6 hereof, if the volume-weighted average closing bid price
of the Common Stock, as reported in The Wall Street Journal, for the 45
consecutive trading days (the "Trading Period") following Borrower's public
press release of its fourth quarter 1999 financial results (such volume-weighted
average closing bid price herein referred to as the "1999 Conversion Price
Adjustment") is a price less than the initial Conversion Price and if the
Company does not achieve June 30, 1999 fiscal year pre-tax income of $3,500,000
excluding extraordinary gains, then the Conversion Price shall be adjusted
downward to an amount equal to 100% of the 1999 Conversion Price Adjustment.  If
an adjustment is required 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, of the facts creating such adjustment and specifying the resultant
adjusted Conversion Price then in effect, which statement shall constitute an
amendment to the Debenture.  The Holder shall not convert this Debenture or sell
any shares of Common Stock during the Trading Period.  Such one-time adjustment
to the Conversion Price shall be subject to the Holder's optional right to
require the Company to redeem this Debenture at the sum equal to the Principal
Amount, together with an amount equal to an 15% annual yield on the Principal
Amount through the Redemption Date, upon notice given in the manner set forth in
Section 4(b) hereof, if the Company reports pre-tax income of less than
$3,500,000, excluding extraordinary gains, for the June 30, 1999 fiscal year.

     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.  REGISTRATION RIGHTS: The shares of Common Stock issued upon conversion
         --------------------                                                  
of this Debenture shall be restricted from transfer by the holder, unless the
shares are duly registered for sale pursuant to the Securities Act of 1933, as
amended, or the transfer is exempt from registration.  The Holder has certain
rights with respect to the registration of shares of Common Stock issued upon
the conversion of this Debenture pursuant to the terms of the Loan Agreement.
Borrower agrees that a copy of the executed Loan Agreement and all amendments
shall be available to the Holder at the offices of the Company.

     10. 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.)

     11. 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 or Agent may exercise any one or
more of the rights and remedies provided in the Loan Documents, as the Holder or
Agent, 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 agrees to pay and shall pay all costs and expenses
(including attorneys' fees and expenses) incurred by the Holder or Agent in
connection with the preservation and enforcement of Holder's rights under the
Loan Agreement, the Debenture, or any other Loan Document.

     12. 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.

     13. 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 appropriate 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.

     14. 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.

     15. 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 Lender is required hereunder and who shall be the sole 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:

     "The Securities represented by this Debenture have 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, donated or otherwise transferred unless the Company shall
     have received an opinion of Legal Counsel for the Company, or such other
     evidence as may be satisfactory to Legal Counsel for the Company, to the
     effect that any such transfer shall not require registration under 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.

     16.  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.

     17.  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 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.

     18.  RIGHTS UNDER LOAN AGREEMENT. This Debenture is issued pursuant to the
          ---------------------------                                          
Convertible Loan Agreement dated of even date herewith among the Company,
Renaissance III and Renaissance PLC, as Lenders, and Agent, and the holders
hereof are entitled to all the rights and benefits.  Both Borrower and Lenders
have participated in the negotiation and preparation of the Loan Agreement and

amendments, additions and substitutions therefor shall be available to the
Holders at the offices of Borrower.

($1,750,000) (the "Principal Amount") and to pay interest on the unpaid
Principal Amount at the rate of 8.75% per annum.  All payments of both principal
and interest shall be made at the address of the Holder hereof as it appears in
the books and records of the Borrower, or at such other place as may be
designated by the Holder hereof.

     1.  INTEREST:  Interest on the Principal Amount outstanding from time to
         ---------                                                           
time shall be payable in monthly installments commencing April 1, 1998, and
subsequent payments shall be made on the first day of each month thereafter

interest at the maximum rate permitted by applicable law.

     2.  MATURITY:  If not sooner paid, redeemed or converted, this Debenture
         ---------                                                           
shall mature on March 2, 2005 at which time the remaining unpaid Principal
Amount, and all accrued and unpaid interest and any other charges then due under
the Loan Agreement, shall be due and payable in full.  This Debenture may be

prepayments of Indebtedness (other than Senior Obligations) which is pari passu
with or subordinated to this Debenture.

     3.  MANDATORY PRINCIPAL INSTALLMENTS:  If this Debenture is not sooner
         ---------------------------------                                 
redeemed or converted as provided hereunder, Borrower shall pay to Holder,
commencing on March 2, 2001 and continuing on the first day of each successive
month thereafter prior to maturity, mandatory principal redemption installments,
each of such installments to be in the amount of Ten Dollars ($10) per Thousand
Dollars ($1,000) of the then remaining Principal Amount, and further, at
maturity, Borrower shall pay to Holder a final installment of the remaining
unpaid Principal Amount, and all accrued and unpaid interest and any other

     4.  OPTIONAL REDEMPTION BY HOLDER:  (a) If at any time after the date
         ------------------------------                                   
hereof (i) the Company's Common Stock, $.001 par value ("Common Stock"), is not
listed on the NASDAQ National Market System ("National Market"), the New York

subsidiaries are sold, without the consent of the Holder, or (v) the Company or
its subsidiaries are merged or consolidated with or into unaffiliated entities,

require this Debenture to be redeemed by the Company at the sum equal to the
Principal Amount, together with an amount equal to an 15% annual yield on the
Principal Amount through the date of redemption (the "Redemption Date").

     (b) If J. William Brandner does not continue to serve the Company in the

on the Principal Amount through the Redemption Date.

     (c) The Holder may exercise its right to require that the Company redeem
this Debenture pursuant to Section 4(a) or Section 4(b) 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 date shall not be less
than 30 days nor more than 60 days after the date of the notice.

     5.  OPTIONAL REDEMPTION BY COMPANY: (a) On any interest payment date, and
         -------------------------------                                      
after prior irrevocable notice as provided for below, this Debenture is
redeemable, in whole but not in part, at 101% of par, together with accrued and
unpaid interest through the Redemption Date, by the Company, if all of the
following conditions are satisfied:  (i) the closing bid price for the Common

bid price test shall be duly adjusted for stock splits, stock dividends,
subdivisions, combinations, mergers, consolidations, and other
recapitalizations.  The Company's right of redemption is subject to the Holder's
prior right of conversion of the Debenture.

     (b) In the event that the conditions for an adjustment in the Conversion
Price pursuant to Section 6(b) and (c) hereof are satisfied, this Debenture is

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

<PAGE>
 
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 face 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:

     (b) Conversion Price.  On the issue date hereof and until such time as an
         -----------------                                                    
adjustment shall occur, the Conversion Price shall be $4.75 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.  Any such adjustment
shall be subject to the Company's optional right to redeem this Debenture as set
forth in Section 5(b) hereof, upon notice given in the manner set forth in
Section 5(c) hereof.

             (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 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.

             (iv)  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.

             (v)   Exceptions.  The term "Additional Common Stock" herein shall
                   ----------          
mean all shares of Common Stock hereafter issued by Borrower (including Common
Stock held in the treasury of Borrower), except (A) Common Stock issued upon the
conversion of any of the Debentures; (B) Common Stock issued upon exercise of
any outstanding

warrants, options or convertible debt instruments; (C) Common Stock issued upon
exercise of outstanding employee stock options; (D) up to 200,000 shares of
Common Stock issuable upon exercise of warrants issued to the Holders; and (E)
up to 200,000 shares of Common Stock to be issued upon exercise of options or
warrants to be granted to its investment advisors for consulting services or to
employees under its employee stock option and stock compensation plans.

     (c) Adjustment for Mergers, Sales 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 exercisable 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 an equal 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 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.

     7.  ONE-TIME ADJUSTMENT TO CONVERSION PRICE.  Notwithstanding the
         ---------------------------------------                      
provisions of Section 6 hereof, if the volume-weighted average closing bid price
of the Common Stock, as reported in The Wall Street Journal, for the 45
consecutive trading days (the "Trading Period") following Borrower's public
press release of its fourth quarter 1999 financial results (such volume-weighted
average closing bid price herein referred to as the "1999 Conversion Price
Adjustment") is a price less than the initial Conversion Price and if the
Company does not achieve June 30, 1999 fiscal year pre-tax income of $3,500,000
excluding extraordinary gains, then the Conversion Price shall be adjusted
downward to an amount equal to 100% of the 1999 Conversion Price Adjustment.  If
an adjustment is required 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, of the facts creating such adjustment and specifying the resultant
adjusted Conversion Price then in effect, which statement shall constitute an
amendment to the Debenture.  The Holder shall not convert this Debenture or sell
any shares of Common Stock during the Trading Period.  Such one-time adjustment
to the Conversion Price shall be subject to the Holder's optional right to
require the Company to redeem this Debenture at the sum equal to the Principal
Amount, together with an amount equal to an 15% annual yield on the Principal
Amount through the Redemption Date, upon notice given in the manner set forth in
Section 4(b) hereof, if the Company reports pre-tax income of less than
$3,500,000, excluding extraordinary gains, for the June 30, 1999 fiscal year.

     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.  REGISTRATION RIGHTS: The shares of Common Stock issued upon conversion
         --------------------                                                  
of this Debenture shall be restricted from transfer by the holder, unless the
shares are duly registered for sale pursuant to the Securities Act of 1933, as
amended, or the transfer is exempt from registration.  The Holder has certain
rights with respect to the registration of shares of Common Stock issued upon
the conversion of this Debenture pursuant to the terms of the Loan Agreement.
Borrower agrees that a copy of the executed Loan Agreement and all amendments
shall be available to the Holder at the offices of the Company.

     10. 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.)

     11. 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 or Agent may exercise any one or
more of the rights and remedies provided in the Loan Documents, as the Holder or
Agent, 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 agrees to pay and shall pay all costs and expenses
(including attorneys' fees and expenses) incurred by the Holder or Agent in
connection with the preservation and enforcement of Holder's rights under the
Loan Agreement, the Debenture, or any other Loan Document.

     12. 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.

     13. 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 appropriate 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.

     14. 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.

     15. 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

to Lender is required hereunder and who shall be the sole 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,

to read as follows:

     hypothecated, donated or otherwise transferred unless the Company shall
     have received an opinion of Legal Counsel for the Company, or such other
     evidence as may be satisfactory to Legal Counsel for the Company, to the
     effect that any such transfer shall not require registration under 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.

     16.  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.

     17.  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 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.

     18.  RIGHTS UNDER LOAN AGREEMENT. This Debenture is issued pursuant to the
          ---------------------------                                          
Convertible Loan Agreement dated of even date herewith among the Company,
Renaissance III and Renaissance PLC, as Lenders, and Agent, and the holders
hereof are entitled to all the rights and benefits.  Both Borrower and Lenders

amendments, additions and substitutions therefor shall be available to the
Holders at the offices of Borrower.

THIS WARRANT AND THE SECURITIES ISSUABLE UPON THE EXERCISE HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933. THEY MAY NOT BE SOLD, OFFERED FOR
SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN

OF COUNSEL SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER
SUCH ACT OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT.


                            STOCK PURCHASE WARRANT
                            ----------------------

     This Stock Purchase Warrant (this "Warrant"), dated March 2, 1998, is
issued to RENAISSANCE CAPITAL GROWTH & INCOME FUND III, INC., a Texas
corporation (the "Holder"), by LA-MAN CORPORATION, a Nevada corporation (the
"Company").

     1.   Purchase of Shares.  Subject to the terms and conditions hereinafter
          ------------------                                                  
set forth, the Holder is entitled, upon surrender of this Warrant at the
principal office of the Company (or at such other place as the Company shall
notify the holder hereof in writing), to purchase from the Company 100,000 fully
paid and non-assessable shares of Common Stock, $.001 par value (the "Common
Stock"), of the Company (as adjusted pursuant to Section 7 hereof, the "Shares")
for the purchase price specified in Section 2 below.

     2.   Purchase Price.  The purchase price for the Shares is $4.32 per share.
          -------------- 
Such price shall be subject to adjustment pursuant to Section 7 hereof (such
price, as adjusted from time to time, is herein referred to as the "Warrant
Price").

     3.   Exercise Period.  This Warrant is exercisable in whole or in part at
          ---------------                                                     
any time from the date hereof through March 2, 2003.

     4.   Method of Exercise.  While this Warrant remains outstanding and
          ------------------                                             
exercisable in accordance with Section 3 above, the Holder may exercise, in
whole or in part, the purchase rights evidenced hereby.  Such exercise shall be
effected by:

          (a)  surrender of this Warrant, together with a duly executed copy of
the form of Exercise Notice attached hereto, to the Secretary of the Company at
its principal offices, and the payment to the Company of an amount equal to the
aggregate purchase price for the number of Shares being purchased; or

          (b)  if the Company's Common Stock is publicly traded as of such date,
the instruction to retain that number of Shares having a value equal to the
aggregate exercise price of the Shares as to which this Warrant is being
exercised and to issue to the Holder the remainder of such Shares computed using
the following formula:
<PAGE>
 
          X =  Y(A-B)
               ------
                 A

Where:    X =  the number of shares of Common Stock to be issued to the Holder.

          Y =  the number of shares of Common Stock as to which this Warrant is
               being exercised.

          A =  the fair market value of one share of Common Stock.

          B =  the Warrant Price.

     As used herein, the "fair market value of one share of Common Stock" shall
mean:

               (1)  Except in the circumstances described in clause (2) or (3)
hereof, the closing price of the Company's Common Stock, as reported in the Wall
Street Journal, on the trading day immediately prior to the date of exercise;

               (2)  If such exercise is in conjunction with a merger,
acquisition or other consolidation pursuant to which the Company is not the
surviving entity, the value received by the holders of the Common Stock pursuant
to such transaction for each share; or

               (3)  If such exercise is in conjunction with the initial public
offering of the Company, the price at which the Common Stock is sold to the
public in such offering.

     5.   Certificates for Shares.  Upon the exercise of the purchase rights
          -----------------------                                           
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued as soon as practicable thereafter, and in any event
within thirty (30) days of the delivery of the subscription notice.

     6.   Reservation of Shares.  The Company covenants that it will at all
          ---------------------                                            
times keep available such number of authorized shares of its Common Stock, free
from all preemptive rights with respect thereto, which will be sufficient to
permit the exercise of this Warrant for the full number of Shares specified
herein.  The Company further covenants that such Shares, when issued pursuant to
the exercise of this Warrant, will be duly and validly issued, fully paid and
non-assessable and free from  all taxes, liens and charges with respect to the
issuance thereof.

     7.   Adjustment of Warrant Price and Number of Shares.  The number and kind
          ------------------------------------------------                      
of securities purchasable upon exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time as follows:

          (a)  Stock Dividends, Subdivisions, Combinations and Other Issuances.
               ---------------------------------------------------------------  
If the Company shall at any time prior to the expiration of this Warrant
subdivide its Common Stock, by stock split or otherwise, combine its Common
Stock or issue additional shares of its Common Stock 

                                       2
<PAGE>
 
as a dividend with respect to any shares of its Common Stock, the number of
Shares issuable on the exercise of this Warrant shall forthwith be
proportionately increased in the case of a subdivision or stock dividend and
proportionately decreased in the case of a combination. Appropriate adjustments
shall also be made to the purchase price payable per share, but the aggregate
purchase price payable for the total number of Shares purchasable under this
Warrant (as adjusted) shall remain the same. Any adjustment under this Section
7(a) shall become effective at the close of business on the date the subdivision
or combination becomes effective or as of the record date of such dividend, or,
in the event that no record date is fixed, upon the making of such dividend.

          (b)  Reclassification, Reorganization, Merger, Sale or Consolidation.
               ---------------------------------------------------------------  
In the event of any reclassification, capital reorganization or other change in
the Common Stock of the Company (other than as a result of a subdivision,
combination or stock dividend provided for in Section 7(a) above) or in the
event of a 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
reclassification, reorganization or change, 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 expiration of this Warrant to purchase, at a total price equal
to that payable upon the exercise of this Warrant immediately prior to such
event, the kind and amount of cash, securities or other property receivable in
connection with such reclassification, reorganization or change, consolidation,
merger or sale, by a holder of the same number of shares of Common Stock as were
exercisable by the Holder immediately prior to such reclassification,
reorganization or change, 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 an equal basis with holders of Common
Stock as if this Warrant had been exercised immediately prior to such event,
less the Warrant Price.  Upon receipt of such payment, if any, the rights of the
Holder shall terminate and cease, and this Warrant 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 Warrant, 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
Warrant.

          (c)  Certain Distributions.  In case the Company shall fix a record
               ---------------------                                         
date for the making of a dividend or distribution of cash, securities or
property to all holders of Common Stock (excluding any dividends or
distributions referred to in Sections 7(a) or 7(b) above, the number of Shares
purchasable upon an exercise of this Warrant after such record date shall be
adjusted to equal

                                       3
<PAGE>
 
the product obtained by multiplying the number of Shares purchasable upon an
exercise of this Warrant immediately prior to such record date by a fraction,
the numerator of which shall be the Warrant Price immediately prior to such
distribution, and the denominator of which shall be the Warrant Price
immediately prior to such distribution, less the fair market value per Share, as
determined by the Holder, of the cash, securities or property so distributed.
Such adjustment shall be made successively whenever any such distribution is
made and shall become effective on the effective date of distribution.

     8.   Pre-Exercise Rights.  Prior to exercise of this Warrant, the Holder
          -------------------                                                
shall not be entitled to any rights of a shareholder with respect to the Shares,
including without limitation, the right to vote such Shares, receive preemptive
rights or be notified of shareholder meetings, and the Holder shall not be
entitled to any notice or other communication concerning the business or affairs
of the Company.

     9.   Restricted Securities.  The Holder understands that this Warrant and
          ---------------------                                               
the Shares purchasable hereunder constitute "restricted securities" under the
federal securities laws inasmuch as they are being, or will be, acquired from
the Company in transactions not involving a public offering and accordingly may
not, under such laws and applicable regulations, be resold or transferred
without registration under the Securities Act of 1933, as amended, or an
applicable exemption from registration.  In this connection, the Holder
acknowledges that Rule 144 of the Securities and Exchange Commission is not now,
and may not in the future be, available for resales of the Shares purchased
hereunder.  The Holder further acknowledges that the Shares and any other
securities issued upon exercise of this Warrant shall bear a legend
substantially in the form of the legend appearing on the face hereof.

     10.  Certification of Investment Purpose.  Unless a current registration
          -----------------------------------                                
statement under the Securities Act of 1933, as amended, shall be in effect with
respect to the securities to be issued upon exercise of this Warrant, the Holder
hereof, by accepting this Warrant, covenants and agrees that, at the time of
exercise hereof, the Holder will deliver to the Company a written certification
that the securities acquired by the Holder are acquired for investments purposes
only and that such securities are not acquired with a view to, or for sale in
connection with, any distribution thereof.

     11.  Registration Rights.  This Warrant and the Shares shall be subject to
          -------------------                                                  
the registration rights set forth in the Convertible Loan Agreement of even date
herewith by and among La-Man Corporation, Renaissance Capital Growth & Income
Fund III, Inc., Renaissance US Growth & Income Trust PLC and Renaissance Capital
Group, Inc., as Agent, and the Holder shall be entitled to all rights and
benefits thereof.

     12.  Successors and Assigns.  The terms and provisions of this Warrant
          ----------------------                                           
shall inure to the benefit of, and be binding upon, the Company and the Holder
and their respective successors and assigns.

     13.  Governing Law.  This Warrant shall be governed by the laws of the
          -------------                                                    
State of Texas, excluding the conflicts of laws provisions thereof.

          ---------------                                                     
any time from the date hereof through March 2, 2003.

     4.   Method of Exercise.  While this Warrant remains outstanding and
          ------------------                                             
exercisable in accordance with Section 3 above, the Holder may exercise, in
whole or in part, the purchase rights evidenced hereby.  Such exercise shall be
effected by:

          (a) surrender of this Warrant, together with a duly executed copy of
the form of Exercise Notice attached hereto, to the Secretary of the Company at
its principal offices, and the payment to the Company of an amount equal to the
aggregate purchase price for the number of Shares being purchased; or

          (b) if the Company's Common Stock is publicly traded as of such date,
the instruction to retain that number of Shares having a value equal to the
aggregate exercise price of the Shares as to which this Warrant is being
exercised and to issue to the Holder the remainder of such Shares computed using
the following formula:
<PAGE>
 
          X =  Y(A-B)
               ------

                 A

Where:    X =  the number of shares of Common Stock to be issued to the Holder.

          Y=  the number of shares of Common Stock as to which this Warrant is
               being exercised.

          A =  the fair market value of one share of Common Stock.

          B =  the Warrant Price.

     As used herein, the "fair market value of one share of Common Stock" shall
mean:

               (1) Except in the circumstances described in clause (2) or (3)
hereof, the closing price of the Company's Common Stock, as reported in the Wall
Street Journal, on the trading day immediately prior to the date of exercise;

               (2) If such exercise is in conjunction with a merger, acquisition
or other consolidation pursuant to which the Company is not the surviving
entity, the value received by the holders of the Common Stock pursuant to such
transaction for each share; or

               (3) If such exercise is in conjunction with the initial public
offering of the Company, the price at which the Common Stock is sold to the
public in such offering.

     5.   Certificates for Shares.  Upon the exercise of the purchase rights
          -----------------------                                           
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued as soon as practicable thereafter, and in any event
within thirty (30) days of the delivery of the subscription notice.

     6.   Reservation of Shares.  The Company covenants that it will at all
          ---------------------                                            
times keep available such number of authorized shares of its Common Stock, free
from all preemptive rights with respect thereto, which will be sufficient to
permit the exercise of this Warrant for the full number of Shares specified
herein.  The Company further covenants that such Shares, when issued pursuant to
the exercise of this Warrant, will be duly and validly issued, fully paid and
non-assessable and free from  all taxes, liens and charges with respect to the
issuance thereof.

     7.   Adjustment of Warrant Price and Number of Shares.  The number and kind
          ------------------------------------------------                      
of securities purchasable upon exercise of this Warrant and the Warrant Price
shall be subject to adjustment from time to time as follows:

          (a) Stock Dividends, Subdivisions, Combinations and Other Issuances.
              ---------------------------------------------------------------  
If the Company shall at any time prior to the expiration of this Warrant
subdivide its Common Stock, by stock split or otherwise, combine its Common
Stock or issue additional shares of its Common Stock

                                       2
<PAGE>
 
as a dividend with respect to any shares of its Common Stock, the number of
Shares issuable on the exercise of this Warrant shall forthwith be
proportionately increased in the case of a subdivision or stock dividend and
proportionately decreased in the case of a combination. Appropriate adjustments
shall also be made to the purchase price payable per share, but the aggregate
purchase price payable for the total number of Shares purchasable under this
Warrant (as adjusted) shall remain the same. Any adjustment under this Section
7(a) shall become effective at the close of business on the date the subdivision
or combination becomes effective or as of the record date of such dividend, or,
in the event that no record date is fixed, upon the making of such dividend.

          (b) Reclassification, Reorganization, Merger, Sale or Consolidation.
              ---------------------------------------------------------------  
In the event of any reclassification, capital reorganization or other change in
the Common Stock of the Company (other than as a result of a subdivision,
combination or stock dividend provided for in Section 7(a) above) or in the
event of a 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
reclassification, reorganization or change, 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 expiration of this Warrant to purchase, at a total price equal
to that payable upon the exercise of this Warrant immediately prior to such
event, the kind and amount of cash, securities or other property receivable in
connection with such reclassification, reorganization or change, consolidation,
merger or sale, by a holder of the same number of shares of Common Stock as were
exercisable by the Holder immediately prior to such reclassification,
reorganization or change, 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 an equal basis with holders of Common
Stock as if this Warrant had been exercised immediately prior to such event,
less the Warrant Price.  Upon receipt of such payment, if any, the rights of the
Holder shall terminate and cease, and this Warrant 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 Warrant, 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
Warrant.

          (c) Certain Distributions.  In case the Company shall fix a record
              ---------------------                                         
date for the making of a dividend or distribution of cash, securities or
property to all holders of Common Stock (excluding any dividends or
distributions referred to in Sections 7(a) or 7(b) above, the number of Shares
purchasable upon an exercise of this Warrant after such record date shall be
adjusted to equal

                                       3
<PAGE>
 
the product obtained by multiplying the number of Shares purchasable upon an
exercise of this Warrant immediately prior to such record date by a fraction,
the numerator of which shall be the Warrant Price immediately prior to such
distribution, and the denominator of which shall be the Warrant Price
immediately prior to such distribution, less the fair market value per Share, as
determined by the Holder, of the cash, securities or property so distributed.
Such adjustment shall be made successively whenever any such distribution is
made and shall become effective on the effective date of distribution.

     8.   Pre-Exercise Rights.  Prior to exercise of this Warrant, the Holder
          -------------------                                                
shall not be entitled to any rights of a shareholder with respect to the Shares,
including without limitation, the right to vote such Shares, receive preemptive
rights or be notified of shareholder meetings, and the Holder shall not be
entitled to any notice or other communication concerning the business or affairs
of the Company.

     9.   Restricted Securities.  The Holder understands that this Warrant and
          ---------------------                                               
the Shares purchasable hereunder constitute "restricted securities" under the
federal securities laws inasmuch as they are being, or will be, acquired from
the Company in transactions not involving a public offering and accordingly may
not, under such laws and applicable regulations, be resold or transferred
without registration under the Securities Act of 1933, as amended, or an
applicable exemption from registration.  In this connection, the Holder
acknowledges that Rule 144 of the Securities and Exchange Commission is not now,
and may not in the future be, available for resales of the Shares purchased
hereunder.  The Holder further acknowledges that the Shares and any other
securities issued upon exercise of this Warrant shall bear a legend
substantially in the form of the legend appearing on the face hereof.

     10.  Certification of Investment Purpose.  Unless a current registration
          -----------------------------------                                
statement under the Securities Act of 1933, as amended, shall be in effect with
respect to the securities to be issued upon exercise of this Warrant, the Holder
hereof, by accepting this Warrant, covenants and agrees that, at the time of
exercise hereof, the Holder will deliver to the Company a written certification
that the securities acquired by the Holder are acquired for investments purposes
only and that such securities are not acquired with a view to, or for sale in
connection with, any distribution thereof.

     11.  Registration Rights.  This Warrant and the Shares shall be subject to
          -------------------                                                  
the registration rights set forth in the Convertible Loan Agreement of even date
herewith by and among La-Man Corporation, Renaissance Capital Growth & Income
Fund III, Inc., Renaissance US Growth & Income Trust PLC and Renaissance Capital
Group, Inc., as Agent, and the Holder shall be entitled to all rights and
benefits thereof.

     12.  Successors and Assigns.  The terms and provisions of this Warrant
          ----------------------                                           
shall inure to the benefit of, and be binding upon, the Company and the Holder
and their respective successors and assigns.

     13.  Governing Law.  This Warrant shall be governed by the laws of the
          -------------                                                    
State of Texas, excluding the conflicts of laws provisions thereof.

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

                                   --------

Secured Parties a security interest in the Shares, together with any additional

     6.   OCCURRENCE OF EVENT OF DEFAULT. If an Event of Default or a Default
          ------------------------------
occurs, subject to the rights of a prior Third-Party Pledgee, each Secured Party
shall have the right to vote the Pledged Shares, to receive dividends with
respect to the Pledged Shares and to exercise any one or more of the rights and
remedies provided in the Loan Agreement, as either Secured Party or Agent, in
its or their sole discretion, may deem necessary or appropriate. Each Secured
Party shall further have the right to exercise any remedies afforded a secured
party under the Uniform Commercial Code of Texas or any other applicable law

enforced in accordance with Texas law.

          b.   Binding Effect.  All of the terms, covenants, representations,

                              SECURITY AGREEMENT
                              ------------------

     This SECURITY AGREEMENT is made and entered into as of this 2nd day of
March, 1998, between LA-MAN CORPORATION, a Nevada corporation (the "Borrower"),
and RENAISSANCE CAPITAL GROWTH & INCOME FUND III, INC. and RENAISSANCE US GROWTH
& INCOME TRUST PLC (each a "Lender" and collectively, the "Lenders").
Capitalized terms used herein, unless otherwise defined herein, have the
definitions given them in the Loan Agreement (as defined below).

     WHEREAS, Lenders, Renaissance Capital Group, Inc. (the "Agent") and the
Borrower, have entered into a Convertible Loan Agreement of even date herewith
(the "Loan Agreement"), pursuant to which Lenders will lend to the Borrower the
aggregate principal amount of $3,500,000 evidenced by the Borrower's 8.75%
Convertible Debentures of even date herewith (the "Debentures");

     WHEREAS, as a condition for entering into the Loan Agreement and providing
the Loan, Lenders required that Borrower grant a security interest in its assets
as collateral for such Loan;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements set forth herein, the parties hereto and hereby agree as follows:

     1.   Grant of Security Interest.  In order to secure payment when due
          --------------------------                                      
of all obligations arising under the Loan Agreement and the Debentures (the
"Obligations"), now existing or hereafter incurred, Borrower hereby irrevocably
grants to Lenders a continuing security interest in the following property of
the Borrower (the "Collateral"), whether now owned or existing, or hereafter
acquired, owned, existing or arising (whether by contract or operation by law),
and wherever located, which shall be retained by Lenders until the Obligations
have been paid in full and the Loan Agreement has been terminated; provided,
however, that the security interest in certain of the Collateral will be
subordinate to existing security interests previously granted to SouthTrust
Bank, National Association:

          a.   All accounts, contract rights, chattel paper and rights of
payment of every kind (collectively, "Accounts") and instruments and general
intangibles of Borrower.

          b.   All bank accounts of Borrower.

          c.   All monies, residues and property of any kind, now or at any time
or times hereafter, in the possession or under the control of Lenders, Agent or
a bailee of Lenders.

          d.   All licenses, patents, patent applications, copyrights,
trademarks, trademark applications, trade names, assumed names, service marks
and service mark applications of Borrower.

          e.   All inventory, equipment (including any and all computer hardware
and components), machinery and fixtures of Borrower in all forms and wherever
located, and all parts and products thereof, all accessories thereto, and all
documents therefor.
<PAGE>
 
          f.   All books and records (including, without limitation, customer
lists, credit files, tapes, ledger cards, computer software and hardware,
electronic data processing software, computer programs, printouts and other
computer materials and records) of Borrower evidencing or containing information
regarding or otherwise pertaining to any of the foregoing.

          g.   All accessories to, substitutions for and all replacements,
products and proceeds of the foregoing, including, without limitation, proceeds
of insurance policies insuring the Collateral (including, but not limited to,
claims paid and premium refunds).

     2.   Insurance on Collateral.  Borrower further warrants and agrees that
          -----------------------                                       
in each case where the terms of any such Accounts require the Borrower or the
account debtor named in such Account to place or carry insurance in respect of
the property to which such Account relates, the Borrower or the account debtor
will pay for and maintain such insurance.

     3.   Delivery of Receivables.  Upon Lenders' or Agent's request, upon the
          -----------------------                                         
occurrence of an Event of Default, the Borrower will, at any reasonable time and
at Borrower's own expense, physically deliver to Lenders or Agent all Accounts
assigned to Lenders at any reasonable place or places designated by Lenders or
Agent. Failure to deliver any Account, or failure to deliver physical possession
of any instruments, documents or writings in respect of any Account shall not
invalidate Lenders' Lien and security interest therein, except to the extent
that possession may be required by applicable law for the perfection of said
Lien or security interest, in which latter case, the Account shall be deemed to
be held by the Borrower as the custodian agent of Lenders, for the benefit of
Lenders. Failure of Lenders or Agent to demand or require Borrower to include
any Account in any schedule, to execute any schedule, to assign and deliver any
schedule or to deliver physical possession of any instruments, documents or
writings related to any Account shall not relieve Borrower of its duty so to do.

     4.   Collection of Receivables.  Borrower hereby agrees that it shall use
          -------------------------                                       
commercially reasonable efforts, at its sole cost and expense and in its own
name, to promptly and diligently collect and enforce payment of all Accounts and
Borrower will defend and hold Lenders harmless from any and all loss, damage,
penalty, fine or expense arising from such collection or enforcement.

     5.   Financing Statements.  Borrower agrees to execute all financing
          --------------------                                           
statements and amendments thereto as Lenders or Agent may request from time to
time to evidence the security interest granted to Lenders hereunder and will pay
all filing fees and taxes, if any, necessary to effect the filing thereof.
Wherever permitted by law, Borrower authorizes Lenders or Agent to file
financing statements with respect to the Collateral without the signature of
Borrower. Without the written consent of Lenders or Agent, Borrower will not
allow any financing statement or notice of assignment to be on file in any
public office covering any Collateral, proceeds thereof or other matters subject
to the security interest granted to Lenders herein, unless such financing
statement relates to a Permitted Lien.

     6.   Lenders' Payment of Claims.  Lenders may, in their sole discretion,
          --------------------------                             
discharge or obtain the release of any security interest, lien, claim or
encumbrance asserted by any Person against

                                       2
<PAGE>
 
the Collateral, other than a Permitted Lien. All sums paid by Lenders in respect
thereof shall be payable, on demand, by Borrower to such Lenders and shall be a
part of the Obligations.

     7.   Default and Remedies.
          -------------------- 

          a.   Borrower shall be in default hereunder upon the occurrence of an
Event of Default, as set forth in the Loan Agreement.

          b.   Upon the occurrence of any Event of Default which shall be
continuing, (i) unless Lenders or Agent shall elect otherwise, the entire unpaid
amount of due under the Continuing Guaranty as are not then otherwise due and
payable shall become immediately due and payable without notice to Borrower or
demand by Lenders or Agent and (ii) any of Lenders or Agent may at its or their
option exercise from time to time any and all rights and remedies available to
them under the Uniform Commercial Code or otherwise, including the right to
foreclose or otherwise realize upon the Collateral and to dispose of any of the
Collateral at one or more public or private sales or other proceedings, and
Borrower agrees that any of Lenders, Agent or their nominee may become the
purchaser at any such sale or sales. Borrower agrees that ten (10) days shall be
reasonable prior notice of the date of any public sale or other disposition of
the same may be made. All rights and remedies granted Lenders hereunder or under
any other agreement between Lenders and Borrower shall be deemed concurrent and
cumulative and not alternative, and Lenders, or Agent on their behalf, may
proceed with any number of remedies at the same time or at different times until
all the Obligations are fully satisfied. The exercise of any one right or remedy
shall not be deemed a waiver or release of or an election against any other
right or remedy. Borrower shall pay to Lenders or Agent on demand any and all
expenses (including reasonable attorneys' fees and legal expenses) which may
have been incurred by Lenders or Agent (i) in the prosecution or defense of any
action growing out of or connected with the subject matter of this Agreement,
the Continuing Guaranty, the Collateral or any of Lenders' rights therein or
thereto; or (ii) in connection with the custody, preservation, use, operation,
preparation for sale or sale of the Collateral, the incurring of all of which
are hereby authorized to the extent Lenders or Agent deem the same advisable.
Borrower's liability to Lenders or Agent for any such payment shall be included
in the Obligations. The proceeds of any Collateral received by Lenders or Agent
at any time before or after default, whether from a sale or other disposition of
Collateral or otherwise, or the Collateral itself, may be applied to the payment
in full or in part of such of the Obligations and in such order and manner as
Lenders or Agent may elect.

     8.   Representations and Covenants of Borrower.  Borrower hereby
          -----------------------------------------                  
represents to and agrees with Lenders as follows:

          a.   Except as referred to in Section 1, Borrower owns the Collateral
as sole owner, free and clear of any Liens.

          b.   So long as any amounts due pursuant to the Loan Agreement remain
unpaid, Borrower agrees not to sell, assign or transfer the Collateral and to
maintain it free and clear of any Liens.

                                       3
<PAGE>
 
     9.   Miscellaneous.
          ------------- 

          a.   This Agreement shall bind and inure to the benefit of the parties
and their respective heirs, personal representatives, successors and assigns,
except that Borrower shall not assign any of its rights hereunder without
Lenders' and Agent's prior written consent.

          b.   Any provision hereof which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without affecting the validity or
enforceability of the remainder of this Agreement or the validity or
enforceability of such provision in any other jurisdiction.

          c.   All issues arising hereunder shall be governed by the laws of the
State of Texas.

          d.   Borrower hereby consents to the jurisdiction of the courts of the
State of Texas in any action or proceeding which may be brought against it under
or in connection with this Agreement or any transaction contemplated hereby or
to enforce any agreement contained herein, and in the event any such action or
proceeding shall be brought against it, Borrower agrees not to raise any
objection to such jurisdiction or to the laying of venue in Dallas County, Texas
or, if applicable, any other county in any state in which Collateral is located.

     IN WITNESS WHEREOF, this Agreement has been duly executed as of the date
and year written above.

                              CONTINUING GUARANTY
                              -------------------

     WHEREAS, the undersigned guarantor (the "Guarantor") is a subsidiary of LA-
MAN CORPORATION, a Nevada corporation (the "Borrower");

     WHEREAS, Renaissance Capital Growth & Income Fund III, a Texas corporation,
and Renaissance US Growth & Income Trust PLC, a public limited company
registered in England and Wales (each a "Lender" and collectively, the
"Lenders"), are willing to make a loan to the Borrower only upon receiving a
continuing guaranty from each of the Borrower's wholly-owned subsidiaries; and

     WHEREAS, Guarantor acknowledges that it will receive a direct benefit by
the Borrower obtaining such a loan;

     NOW, THEREFORE, IN CONSIDERATION OF THE FOREGOING, the undersigned for
itself, its successors and assigns, unconditionally guarantees to the Lenders,
and its agents, successors, participants, endorsees and/or assigns, the due
performance and full and prompt payment, whether at maturity, by acceleration,
or otherwise, of any and all Obligations and Indebtedness of the Borrower to
Lenders pursuant to the Convertible Loan Agreement (as amended from time to
time, the "Loan Agreement"), of even date herewith among Borrower, Lenders and
Renaissance Capital Group, Inc., as Agent for the Lenders, including, but not
limited to, a loan (the "Loan") from Lenders to Borrower in the aggregate sum of
THREE MILLION FIVE HUNDRED THOUSAND AND NO/100 DOLLARS ($3,500,000.00),
evidenced by those certain 8.75% Convertible Debentures from Borrower in favor
of Lenders dated of even date herewith (the "Debentures").

     This is a Continuing Guaranty relating to said all such Indebtedness and
Obligations and is not limited as to amount.  Further, this Continuing Guaranty
shall remain in effect whether recovery on any such Indebtedness or Obligations
may become barred by any statute of limitations or equitable estoppel or whether
any such Indebtedness or Obligations may be or hereafter become otherwise
unenforceable.

     The obligations hereunder are independent of the obligations of Borrower,
and a separate action or actions may be brought and prosecuted against
Guarantor, whether or not action is brought against Borrower, Borrower may be
joined in any such action or actions.  If separate guaranties of the Borrower's
indebtedness to Lenders are executed by other guarantors, the obligations of
Guarantor hereunder shall be joint and several with those of the other
guarantors and may be enforced regardless of the enforcement of other
guaranties.  This is a guaranty of payment and not of collection.

     Guarantor acknowledges and agrees with Lenders that each indebtedness is a
valid and binding obligation of Borrower. Guarantor authorizes Lenders, without
notice or demand, and without affecting its liability hereunder, from time to
time, and on any number of occasions, to (a) renew, amend, compromise, extend,
accelerate, reinstate, or otherwise change the time for payment
<PAGE>
 
of, or otherwise change the terms of, the indebtedness or any part thereof,
including increasing or decreasing the interest rate thereon; (b) take and hold
security for the payment of this Continuing Guaranty or the indebtedness, and
exchange, enforce, waive and release any such security; (c) apply such security
and direct the order or manner of sale thereof as Lenders in their discretion
may elect from time to time; and (d) release or substitute any one or more of
the endorsers or guarantors. Guarantor acknowledges and agrees that no act or
omission of any kind by Lenders, including, but not limited to, the failure to
take or perfect a security interest in any security for the indebtedness shall
affect or impair this Continuing Guaranty, and the Lenders shall have no duties
with respect thereof to any Guarantor. Lenders may without notice assign this
Continuing Guaranty in whole or in part at any time.

     Guarantor waives any right to require Lenders to (a) proceed against
Borrower; (b) proceed against or exhaust any security held from Borrower; or (c)
pursue any other remedy whatsoever available to Lenders. Guarantor waives any
defense arising by reason of any disability or other defense of Borrower or by
reason of the cessation from any cause whatsoever of Borrower's liability or by
reason of Lenders releasing any security held from Borrower. Until all of
Borrower's indebtedness to Lenders shall have been paid in full, Guarantor shall
have no right of subrogation, and Guarantor waives any right to enforce any
remedy that Lenders now have or may hereafter have against Borrower, and shall
waive any benefit of, and any right to participate in, any security now or
hereafter held by Lenders. Guarantor waives all presentments, demands for
performance, notices of nonperformance, protests, notices of dishonor, and
notices of acceptance of this Continuing Guaranty and of the existence,
creation, or incurrence of new or additional indebtedness and all other defenses
to any action or proceeding to enforce this Continuing Guaranty, except the
single defense that the sum claimed has actually been paid to Lenders. Guarantor
covenants to maintain and preserve the enforceability of any instruments now or
hereafter executed by Guarantor in favor of the Lenders. Guarantor covenants and
agrees that no action of any kind taken by Borrower shall be the basis for a
claim that Guarantor has any defense hereunder other than payment in full of all
Borrower's indebtedness to Lenders. Guarantor hereby indemnifies Lenders against
any loss, cost, or expense by reason of the assertion by Guarantor of any
defense hereunder based upon any such action or inaction of Borrower. Guarantor
waives any right or claim of right to cause a marshaling of the Borrower's
assets. No delay on the part of Lenders in the exercise of any right, power or
privilege under the terms of any documentation between Lenders and Borrower or
under this Continuing Guaranty shall operate as a waiver of any such privilege,
power or right.

     In addition to all liens upon, and rights to set off against, the monies,
securities or other property of Guarantor given to Lenders by law, Guarantor
agrees that Lenders shall have a lien upon, and a right to set off against, all
monies, securities, and other property of Guarantor now or hereafter in
possession of or on deposit with Lenders, whether held in a general or special
account of deposit, or for safekeeping or otherwise; and, every such lien and
right to set off may be exercised without demand upon or notice to Guarantor.
No lien or right to set off shall be deemed to have been waived by any act or
conduct on the part of Lenders, or by any neglect to exercise such right to set
off or to enforce such lien, or by any delay in so doing; and every right to set
off and lien shall continue in full force and effect until such right to set off
or lien is specifically waived or released by an instrument in writing executed
by Lenders.

                                       2

     Guarantor acknowledges and agrees with Lenders that any and all
indebtedness of Borrower now or hereafter held by Guarantor is hereby
subordinated to the indebtedness of Borrower to Lenders; and such indebtedness
of Borrower to Guarantor, if Lenders so request, shall be collected, enforced
and received by Guarantor as trustee for Lenders and be paid over to Lenders on
account of the indebtedness of Borrower to Lenders, but without reducing or
affecting in any manner the liability of Guarantor under the other provisions of
this Continuing Guaranty.

     Guarantor agrees to pay all attorneys' fees and all other costs and
expenses that may be incurred or expended by Lenders in the enforcement of
Borrower's obligations and of this Continuing Guaranty, whether suit be brought
or not, and if suit is brought, then for all services in trial and appellate
courts.

     Upon default of Borrower in any of its obligations or liabilities to
Lenders, or if Borrower or Guarantor shall become insolvent or make an
assignment for the benefit of creditors, or if a petition in bankruptcy or for
corporate reorganization or for an arrangement be filed by or against Borrower
or Guarantor, or if there is the appointment of a receiver for Borrower or for
Guarantor or their property, or if a judgment is obtained or warrant of
attachment issued against Borrower or Guarantor, all of the indebtedness, shall,
without notice or demand, at the option of Lenders, become immediately due and
payable and shall be paid forthwith by Guarantor.

     If the Borrower is a corporation or a partnership, it shall not be
necessary for the Lenders to inquire into the existence or powers of the
Borrower, or the officers, directors, partners, or agents acting or purporting
to act on the Borrower's behalf, and any indebtedness made or created upon the
professed exercise of such existence or powers shall be guaranteed hereunder.

     Guarantor hereby submits to the jurisdiction of the state and federal
courts in the State of Texas for purposes of any action arising from or growing
out of this Continuing Guaranty, and further agrees that the venue of any action
may be laid in Dallas County or, if applicable, any other county in any state in
which real property which secures any of the indebtedness is located.  Nothing
contained in this Continuing Guaranty, however, shall be deemed to constitute,
or to imply the existence of, any agreement by Lenders to bring any action only
in said courts or to restrict in any way any of Lenders' remedies or rights to
enforce the terms of this Continuing Guaranty as, when and where Lenders shall
deem appropriate, in their sole discretion.

     Notwithstanding any provision herein or in any instrument now or hereafter
evidencing said indebtedness, the total liability for payments in the nature of
interest under this Continuing Guaranty shall not exceed the limits imposed from
time to time by applicable usury laws.  This Continuing Guaranty shall be
accepted, at the offices of Lenders in Dallas, Texas and for all purposes, be
governed by and construed with the laws of the State of Texas.

     Guarantor acknowledges that Lenders have been induced by this Continuing
Guaranty to extend the credit to Borrower creating the indebtedness, and that
Lenders would not have extended said credit without this Continuing Guaranty,
and this Continuing Guaranty shall, without further 

                                       3
<PAGE>
 
reference or assignment, pass to, and may be relied upon and enforced by, any
successor or participant or assignee of Lenders.

     No amounts paid under this Continuing Guaranty shall in any way or at any
time entitle Guarantor to any right, claim or cause of action against the
Borrower, or to any right, title or interest in or to any of the indebtedness or
any rights of the Lenders, or in or to any instruments or documents evidencing
or securing or concerning the indebtedness, and Guarantor hereby waives, for the
benefit of the Lenders and the Borrower, any and all such rights (whether
arising by way of subrogation, exoneration, reimbursement, participation,
assignment, judicial decision, statute, constitutional provision, or otherwise)
which Guarantor might otherwise have had in the absence of this waiver and which
would have otherwise entitled Guarantor to be a "creditor" of the Borrower under
the provisions of the U.S. Bankruptcy Code (Title 11, U.S. Code) or any other
bankruptcy or insolvency law.

     Guarantor acknowledges and agrees that this Continuing Guaranty shall
remain in full force and effect until all indebtedness of Borrower to Lenders is
paid in full and that if Lenders are required by a court of competent
jurisdiction to refund or repay to the Borrower or on behalf of the Borrower any
amounts received in reduction or satisfaction of the indebtedness, then and in
that event the liabilities of Guarantor in regard to said amounts shall be
reinstated and this Continuing Guaranty shall remain in full force and effect in
respect thereto.  Furthermore, Guarantor agrees that this Continuing Guaranty
shall continue to be effective or shall be reinstated, as the case may be, at
any time payment, or any part thereof, of principal or interest charges, or
other related expenses of the obligations are rescinded or otherwise forgiven by
Lenders upon the bankruptcy or reorganization of Borrower or Guarantor.

     Guarantor agrees to furnish to Lenders within sixty (60) days after the end
of its fiscal year a complete financial statement of Guarantor, including a
statement of income and expenses and a balance sheet indicating net worth,
prepared by an independent certified public accountant and prepared in
accordance with generally accepted accounting principles, applied on a
consistent basis and certified by Guarantor as true and correct.

     This Continuing Guaranty may be executed in any number of counterparts,
each of which shall be deemed an original, but all of which together shall
constitute but one instrument.

     Each provision hereof is intended to be severable and the invalidity or
illegality of any portion of this Continuing Guaranty shall not affect the
validity or legality of the remainder hereof.

     Capitalized terms used but not defined herein shall have the respective
meanings set forth in the Loan Agreement.

     LENDERS BY THEIR ACCEPTANCE HEREOF AND GUARANTOR HEREBY VOLUNTARILY,

LEGAL ACTION OR PROCEEDING ARISING UNDER THIS GUARANTY OR CONCERNING THE
INDEBTEDNESS AND/OR COLLATERAL THEREFOR OR PERTAINING TO ANY TRANSACTION RELATED
TO OR CONTEMPLATED THEREBY, REGARDLESS OF WHETHER SUCH ACTION OR PROCEEDING
CONCERNS ANY CONTRACTUAL OR TORTIOUS OR OTHER CLAIM.  GUARANTOR ACKNOWLEDGES
THAT THIS WAIVER OF JURY TRIAL IS A MATERIAL INDUCEMENT TO THE LENDERS IN
EXTENDING CREDIT TO THE BORROWER, THAT THE LENDERS WOULD NOT HAVE EXTENDED SUCH
CREDIT WITHOUT THIS JURY TRIAL WAIVER, AND THAT GUARANTOR HAS BEEN REPRESENTED
BY AN ATTORNEY OR HAVE HAD AN OPPORTUNITY TO CONSULT WITH AN ATTORNEY IN
CONNECTION WITH THIS JURY TRIAL WAIVER AND UNDERSTAND THE LEGAL EFFECT OF THIS
WAIVER.

                              SECURITY AGREEMENT
                              ------------------

          This SECURITY AGREEMENT is made and entered into as of this 2nd day of
March, 1998, between CERTIFIED MAINTENANCE SERVICES, INC., a Florida corporation
(the "Guarantor"), and RENAISSANCE CAPITAL GROWTH & INCOME FUND III, INC. and
RENAISSANCE US GROWTH & INCOME TRUST PLC (each a "Lender" and collectively, the
"Lenders").  Capitalized terms used herein, unless otherwise defined herein,
have the definitions given them in the Loan Agreement (as defined below).

          WHEREAS, Lenders, Renaissance Capital Group, Inc. (the "Agent") and
La-Man Corporation (the "Borrower"), have entered into a Convertible Loan
Agreement of even date herewith (the "Loan Agreement"), pursuant to which
Lenders will lend to the Borrower the aggregate principal amount of $3,500,000
evidenced by the Borrower's 8.75% Convertible Debentures of even date herewith
(the "Debentures");

          WHEREAS, as a condition for entering into the Loan Agreement and
providing the Loan, Lenders required that Guarantor, a subsidiary of the
Borrower, guarantee the obligations of the Borrower and grant a security
interest in the assets of the Guarantor as collateral for such guaranty; and

          WHEREAS, the Guarantor executed a Continuing Guaranty of even date
herewith in favor of Lenders (the "Continuing Guaranty"), whereby Guarantor
guaranteed the due performance and full and prompt payment of all obligations
and indebtedness of the Borrower arising under the Loan Agreement;

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements set forth herein, the parties hereto and hereby agree
as follows:

          1.   Grant of Security Interest.  In order to secure payment when due
               --------------------------                                      
of all obligations arising under the Continuing Guaranty (the "Obligations"),
now existing or hereafter incurred, Guarantor hereby irrevocably grants to
Lenders a continuing security interest in the following property of the
Guarantor (the "Collateral"), whether now owned or existing, or hereafter
acquired, owned, existing or arising (whether by contract or operation by law),
and wherever located, which shall be retained by Lenders until the Obligations
have been paid in full and the Loan Agreement has been terminated; provided,
however, that the security interest in certain of the Collateral will be
subordinate to existing security interests previously granted to SouthTrust
Bank, National Association:

               a.   All accounts, contract rights, chattel paper and rights of
payment of every kind (collectively, "Accounts") and instruments and general
intangibles of Guarantor.

               b.   All bank accounts of Guarantor.

               c.   All monies, residues and property of any kind, now or at any
time or times hereafter, in the possession or under the control of Lenders,
Agent or a bailee of Lenders.
<PAGE>
 
               d.   All licenses, patents, patent applications, copyrights,
trademarks, trademark applications, trade names, assumed names, service marks
and service mark applications of Guarantor.

               e.   All inventory, equipment (including any and all computer
hardware and components), machinery and fixtures of Guarantor in all forms and
wherever located, and all parts and products thereof, all accessories thereto,
and all documents therefor.

               f.   All books and records (including, without limitation,
customer lists, credit files, tapes, ledger cards, computer software and
hardware, electronic data processing software, computer programs, printouts and
other computer materials and records) of Guarantor evidencing or containing
information regarding or otherwise pertaining to any of the foregoing.

               g.   All accessories to, substitutions for and all replacements,
products and proceeds of the foregoing, including, without limitation, proceeds
of insurance policies insuring the Collateral (including, but not limited to,
claims paid and premium refunds).

          2.   Insurance on Collateral.  Guarantor further warrants and agrees
               -----------------------                                        
that in each case where the terms of any such Accounts require the Guarantor or
the account debtor named in such Account to place or carry insurance in respect
of the property to which such Account relates, the Guarantor or the account
debtor will pay for and maintain such insurance.

          3.   Delivery of Receivables.  Upon Lenders' or Agent's request, upon
               -----------------------                                         
the occurrence of an Event of Default, the Guarantor will, at any reasonable
time and at Guarantor's own expense, physically deliver to Lenders or Agent all
Accounts assigned to Lenders at any reasonable place or places designated by
Lenders or Agent.  Failure to deliver any Account, or failure to deliver
physical possession of any instruments, documents or writings in respect of any
Account shall not invalidate Lenders' Lien and security interest therein, except
to the extent that possession may be required by applicable law for the
perfection of said Lien or security interest, in which latter case, the Account
shall be deemed to be held by the Guarantor as the custodian agent of Lenders,
for the benefit of Lenders.  Failure of Lenders or Agent to demand or require
Guarantor to include any Account in any schedule, to execute any schedule, to
assign and deliver any schedule or to deliver physical possession of any
instruments, documents or writings related to any Account shall not relieve
Guarantor of its duty so to do.

          4.   Collection of Receivables.  Guarantor hereby agrees that it shall
               -------------------------                                        
use commercially reasonable efforts, at its sole cost and expense and in its own
name, to promptly and diligently collect and enforce payment of all Accounts and
Guarantor will defend and hold Lenders harmless from any and all loss, damage,
penalty, fine or expense arising from such collection or enforcement.

          5.   Financing Statements.  Guarantor agrees to execute all financing
               --------------------                                            
statements and amendments thereto as Lenders or Agent may request from time to
time to evidence the security interest granted to Lenders hereunder and will pay
all filing fees and taxes, if any, necessary to effect the filing thereof.
Wherever permitted by law, Guarantor authorizes Lenders or Agent to file
financing statements with respect to the Collateral without the signature of
Guarantor. Without the

                                       2
<PAGE>
 
written consent of Lenders or Agent, Guarantor will not allow any financing
statement or notice of assignment to be on file in any public office covering
any Collateral, proceeds thereof or other matters subject to the security
interest granted to Lenders herein, unless such financing statement relates to a
Permitted Lien.

          6.   Lenders' Payment of Claims.  Lenders may, in their sole
               --------------------------                             
discretion, discharge or obtain the release of any security interest, lien,
claim or encumbrance asserted by any Person against the Collateral, other than a
Permitted Lien.  All sums paid by Lenders in respect thereof shall be payable,
on demand, by Guarantor to such Lenders and shall be a part of the Obligations.

          7.   Default and Remedies.
               -------------------- 

               a.   Guarantor shall be in default hereunder upon the occurrence
of an Event of Default, as set forth in the Loan Agreement.

               b.   Upon the occurrence of any Event of Default which shall be
continuing, (i) unless Lenders or Agent shall elect otherwise, the entire unpaid
amount of due under the Continuing Guaranty as are not then otherwise due and
payable shall become immediately due and payable without notice to Guarantor or
demand by Lenders or Agent and (ii) any of Lenders or Agent may at its or their
option exercise from time to time any and all rights and remedies available to
them under the Uniform Commercial Code or otherwise, including the right to
foreclose or otherwise realize upon the Collateral and to dispose of any of the
Collateral at one or more public or private sales or other proceedings, and
Guarantor agrees that any of Lenders, Agent or their nominee may become the
purchaser at any such sale or sales.  Guarantor agrees that ten (10) days shall
be reasonable prior notice of the date of any public sale or other disposition
of the same may be made.  All rights and remedies granted Lenders hereunder or
under any other agreement between Lenders and Guarantor shall be deemed
concurrent and cumulative and not alternative, and Lenders, or Agent on their
behalf, may proceed with any number of remedies at the same time or at different
times until all the Obligations are fully satisfied.  The exercise of any one
right or remedy shall not be deemed a waiver or release of or an election
against any other right or remedy.  Guarantor shall pay to Lenders or Agent on
demand any and all expenses (including reasonable attorneys' fees and legal
expenses) which may have been incurred by Lenders or Agent (i) in the
prosecution or defense of any action growing out of or connected with the
subject matter of this Agreement, the Continuing Guaranty, the Collateral or any
of Lenders' rights therein or thereto; or (ii) in connection with the custody,
preservation, use, operation, preparation for sale or sale of the Collateral,
the incurring of all of which are hereby authorized to the extent Lenders or
Agent deem the same advisable.  Guarantor's liability to Lenders or Agent for
any such payment shall be included in the Obligations.  The proceeds of any
Collateral received by Lenders or Agent at any time before or after default,
whether from a sale or other disposition of Collateral or otherwise, or the
Collateral itself, may be applied to the payment in full or in part of such of
the Obligations and in such order and manner as Lenders or Agent may elect.

          8.   Representations and Covenants of Guarantor.  Guarantor hereby
               ------------------------------------------                   
represents to and agrees with Lenders as follows:

               a.   Except as referred to in Section 1, Guarantor owns the
Collateral as sole owner, free and clear of any Liens.

               b.   So long as any amounts due pursuant to the Loan Agreement
remain unpaid, Guarantor agrees not to sell, assign or transfer the Collateral
and to maintain it free and clear of any Liens.

          9.   Miscellaneous.
               ------------- 

               a.   This Agreement shall bind and inure to the benefit of the
parties and their respective heirs, personal representatives, successors and
assigns, except that Guarantor shall not assign any of its rights hereunder
without Lenders' and Agent's prior written consent.

               b.   Any provision hereof which is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without affecting the validity or
enforceability of the remainder of this Agreement or the validity or
enforceability of such provision in any other jurisdiction.

               c.   All issues arising hereunder shall be governed by the laws
of the State of Texas.

               d.   Guarantor hereby consents to the jurisdiction of the courts
of the State of Texas in any action or proceeding which may be brought against
it under or in connection with this Agreement or any transaction contemplated
hereby or to enforce any agreement contained herein, and in the event any such
action or proceeding shall be brought against it, Guarantor agrees not to raise
any objection to such jurisdiction or to the laying of venue in Dallas County,
Texas or, if applicable, any other county in any state in which Collateral is
located.

          IN WITNESS WHEREOF, this Agreement has been duly executed as of the
date and year written above.

     As approved by the Board of Directors of La Man corporation (the "Company")
at a meeting held on August 29, 1997, the Company's 1992 Stock Option and 
Appreciation Rights Plan, as amended, is hereby further amended by deleting 
Section 2.5 thereof in its entirety and substituting in lien thereof the

                                AMENDMENT NO. 3
                                       TO
                               LA-MAN CORPORATION
           1992 STOCK OPTION AND APPRECIATION RIGHTS PLAN, AS AMENDED

     This Amendment No. 3 ("Amendment") to the La-Man Corporation 1992 Stock
Option and Appreciation Rights Plan (the "Plan") is deemed effective as of
August 29, 1997.

1.   DEFINITIONS.  Except as otherwise defined herein, all capitalized terms
used in this Amendment have the meanings ascribed to them in the Plan.

2.   AMENDMENT OF ARTICLE VI.  Article VI of the Plan is hereby amended by
deleting therefrom Section 6.4 in its entirety and substituting in lieu thereof
the following:

          "Section 6.4.  In the event of the death of an optionee, the option
     rights of such optionee under any then outstanding Non-Qualified Options
     shall be exercisable by the persons or persons to whom such rights pass by
     will, or by the laws of descent and distribution, at any time prior to the
     earlier of the expiration date of such option or six (6) months following
     the date of such optionee's death.  If a person or estate acquires the
     right to exercise a Non-Qualified Option by bequest or inheritance, the
     Committee may require reasonable evidence as to the ownership of such
     option, and may require such consents and releases of taxing authorities as
     the Committee may deem advisable."

3.   AMENDMENT OF ARTICLE VII.  Article VII is hereby amended by deleting
Section 7.6 thereof in its entirety and inserting in lieu thereof the following:

          "Section 7.6.  The holder of an option may also, at any time prior to
     the exercise thereof, surrender all or part of the option to the extent
     that such option is exercisable and receive in exchange an amount equal to
     the difference between the then fair market value of the shares issuable
     upon the exercise of the option or portion thereof surrendered and the
     option price payable upon the exercise of the option or portion thereof
     surrendered (the "Spread").  Such rights: (a) will expire no later than the
     expiration of the underlying option; (b) may be for no more than 100% of
     the Spread; (c) will be transferrable only if and when the underlying
     option is transferable, and under the same conditions; (d) shall be
     exercised only when the underlying option is eligible to be exercised; and
     (e) may be exercised only when the Spread is positive, i.e., when the
     market price of the Common Stock subject to the option exceeds the exercise
     price of the option."

     Except as amended by this Amendment, all terms and provisions of the Plan
shall remain in full force and effect.

                                AMENDMENT NO.2

                            AMENDMENT AND RESTATED
               LA-MAN CORPORATION 1994 EMPLOYEE AND CONSULTANT 
                      STOCK COMPENSATION PLAN, AS AMENDED

     This Amendment No.2 ("Amendment") to the La-Man Corporation Amended and 
Restated 1994 Employee and Consultant Stock Compensation Plan, as amended (the 
"Plan"), is deemed effective as of August 29, 1997.

1.   DEFINITIONS. The Plan is hereby amended by changing all references to 
"Finance Committee" therein to "Compensation Committee." Except as otherwise 
defined herein, all capitalized terms used in this Amendment have the meanings 
ascribed to them in the Plan.

2.   AMENDMENT OF ARTICLE VIII OF THE PLAN. Article VIII of the Plan is amended
by adding at the end thereof the following:


     "Subject to the provisions of the applicable option agreement, including
     any provisions relating to vesting of an Option an optionee may exercise an
     Option, in whole or in part, only by written notice to the Company stating
     in such written notice the number of shares such optionee elects to
     purchase under the Option, and the time of the delivery thereof, which time
     shall be at least 15 days after the giving of such notice, unless an
     earlier date shall have been mutually agreed upon. If after receipt of such
     information, the optionee desires to withdraw such notice of exercise, the
     optionee may withdraw such notice of exercise by notifying the Company, in
     writing, prior to the time set forth for delivery of the shares. In no
     event shall an Option be exercised after the expiration of its term. An
     optionee is under no obligation to exercise an Option or any part thereof.

     The consideration to be paid for shares to be issued upon exercise of an
     Option may consist in whole or in part of (a) cash, (b) check, or (c) other
     shares of Common Stock which (i) in the case of shares acquired upon
     exercise of an Option either have been owned by the optionee for more than
     six (6) months on the date of surrender or were not acquired, directly or
     indirectly, from the Company, and (ii) have a fair market value (as
     determined by the Board or the Compensation Committee) on the date of












<PAGE>
 
surrender equal to the aggregate exercise price of the shares as to which such 
Option is exercised.

Provided the optionee has delivered proper notice of exercise and full payment 
of the exercise price the Company shall undertake and follow all necessary 
procedures to make prompt delivery of the number of shares which the optionee
elects to purchase at the time specified in such notice. Such delivery, however,
may be postponed at the sole discretion of the Company to enable the Company to
comply with any applicable procedures, regulations or listing requirements of
any governmental agency, stock exchange or regulatory authority. As a condition
to the issuance of shares, the Company may require such additional payments from
the optionee or may, at its option, reduce the number of shares to be delivered
to the optionee, as may be required to allow the Company to withhold any income
taxes which the Company deems necessary to ensure the Company's compliance with 
federal or state income tax withholding requirements.

The holder of an Option may also, at any time prior to the exercise thereof, 
surrender all or part of the Option to the extent that such Option is 
exercisable and receive in exchange an amount equal to the difference between
the then fair market value of the shares issuable upon the exercise of the
Option or portion thereof surrendered and the option price payable upon the
exercise of the Option or portion thereof surrendered (the "Spread"). Such
rights: (a) will expire no later than the expiration of the underlying Option;
(b) may be for no more than 100% of the Spread; (c) will be transferrable only
if and when the underlying Option is transferable, and under the same
conditions; (d) shall be exercised only when the underlying Option is eligible
to be exercised; and (e) may be exercised only when the Spread is positive,
i.e., when the market price of the Common Stock subject to the Option exceeds
the exercise price of the Option.

In the event that any holder of an outstanding Option no longer meets the 
definition of Eligible Participant as the result of disability (as defined in 
Section 22 (?)(3) of the Internal Revenue Code of 1986, as amended), then all 
Option exercise rights of such holder hereunder shall be exercisable by such 
holder at any time prior to the earlier of the applicable expiration date of 
                                ----------
such Option or twelve (12) months following the date of termination of 
employment or service due to disability.

In the event that any holder of an outstanding Option no longer meets the 
definition of Eligible Participant as the result of death, then all Option 
exercise rights of such holder hereunder shall be exercisable by the person or 
persons to whom such rights pass by will or by the laws of descent and 

                                       2

     distribution, at any time prior to the earlier of (a) the applicable
                                            ----------
     expiration date of such Option or (b) six (6) months following the date of
     such holder's death (or such shorter period of time as may be provided in
     the option agreement pursuant to which such Option was granted). If a
     person or estate acquires the right to exercise an Option by bequest or
     inheritance, the Company may require reasonable evidence as to the
     ownership of the Option so acquired, and may require such consents and
     releases of taxing and other governmental authorities as the Company may
     deem advisable."

     Except as amended by this Amendment, all terms and provisions of the Plan
shall remain in full force and effect.
