                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

BASIS OF PRESENTATION OF INTERIM FINANCIAL STATEMENTS

          The accompanying unaudited consolidated financial statements of
Landmark Graphics Corporation and subsidiaries (the "Company") have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission.  Accordingly, certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted. These financial
statements should be read in conjunction with the audited financial statements
and accompanying notes included in the Company's 1994 Annual Report on Form
10-K.

          The Consolidated Statements of Operations for the three month and six
month periods ended December 31, 1993 and the Consolidated Balance Sheet as of
June 30, 1994 have been restated to include the accounts of Stratamodel Inc.
("Stratamodel").  On September 28, 1994, the Company acquired all of the equity
interests of Stratamodel in a transaction accounted for as a pooling of
interests.

         The unaudited consolidated financial statements reflect all
adjustments (consisting only of normal recurring adjustments and adjustments to
reflect the pooling of interests) which the Company considers necessary for a
fair presentation of the interim periods.  Results for the interim periods are
not necessarily indicative of results for the year.  All significant
intercompany balances and transactions have been eliminated.

RECLASSIFICATIONS

         Certain prior year amounts have been reclassified to conform to the
current year presentation.

ACQUISITIONS

Stratamodel

       Stratamodel is engaged in the development of reservoir characterization
and modeling software products designed to aid geoscientists in oil and gas
exploration and production.  In connection with the acquisition, the Company
issued a total of 413,911 shares of its common stock, in exchange for all of
the equity interests of Stratamodel, which included common stock, stock options
and warrants.  In addition, the Company retired all of Stratamodel's
outstanding debt of approximately $510,000 and paid certain acquisition-related
expenses of Stratamodel of approximately $293,000.

          Stratamodel previously reported its financial results on a December
31 fiscal year-end basis.  In connection with the acquisition, Stratamodel
changed its fiscal year-end from December 31 to June 30.  As a result, the
financial statements presented combine both entities' financial results for the
same periods.  In addition to the adjustments made to effect the change in
fiscal years, certain adjustments were made in order to conform Stratamodel's
method of accounting for  software development costs and income taxes to the
Company's method.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         The Company capitalizes software development costs when an operative
version of the product is ready for initial testing, whereas Stratamodel
capitalized costs at points prior to initial testing.  Additionally, the
Company accounted for income taxes under Accounting Principles Board Opinion
No. 11 until it was required to adopt Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes" ("SFAS 109").  Stratamodel had
applied Statement of Financial Accounting Standards No. 96, "Accounting for
Income Taxes" until adopting SFAS 109.  In connection with the acquisition,
Stratamodel conformed it's accounting policies to those of the Company.  The
effect of these conforming adjustments decreased Stratamodel's net income for
the three months and six months ended December 31, 1993 by approximately
$190,000 and $33,000, respectively.

         The Stratamodel acquisition was consummated on September 28, 1994.
The following summarizes the revenues and net income (loss) of the separate
companies included in the results of operations for the three months ended
September 30 (in thousands) (unaudited):

MGA

         On September 29, 1994, the Company purchased all the issued and
outstanding capital stock of MGI Associates, Inc., ("MGA").  The acquisition
was recorded using the purchase method of accounting and, accordingly, the
acquired operations of MGA have been included in the results of operations
since the date of acquisition.

         MGA, based in Dallas, Texas, develops personal computer-based
economics and reservoir engineering software products designed to aid
geoscientists in oil and gas exploration. The Company acquired MGA for
consideration of approximately $13.3 million which consisted of cash of $10.5
million paid to acquire the stock, cash of $1.3 million paid to retire certain
related party debt and the accrual of approximately $1.6 million of
acquisition-related costs.  The acquisition was accounted for using the
purchase method of accounting and, accordingly, the purchase price has been
allocated to the net assets acquired based on estimated fair market values at
the date of acquisition.

         In addition to the $1.6 million software development costs capitalized
in the six months ended December 31, 1994, the Company recorded approximately
$573,000 of software development costs in connection with the MGA acquisition.
The amounts recorded in connection with the MGA acquisition reflect the fair
market value of the software acquired.

GOODWILL

         Goodwill represents the cost in excess of the fair market value of the
net assets of companies acquired and is being amortized on a straight-line
basis over eight years.  During the current quarter, the Company finalized the
purchase price allocation for the acquisition of MGA and adjusted the goodwill
recorded to $11.6 million.

         The valuation allowance is offset against the total deferred tax
assets to reflect the net deferred tax assets.  The net deferred tax assets
reflect the portion which the Company believes there is a greater than 50
percent probability of realization.

MERGER COSTS

         Merger costs included in the Consolidated Statements of Operations
consist primarily of accounting, legal and investment banking costs related to
the completion of the Stratamodel acquisition.

RESTRUCTURING CHARGES AND NON-RECURRING COSTS

         In connection with the Stratamodel acquisition, the Company adopted a
restructuring plan designed to eliminate redundancies and consolidate
operations.  Under the plan, the Company recorded approximately $1.2 million in
restructuring charges consisting of severance costs for terminated employees
and lease costs associated with duplicate facilities.  Additionally,
non-recurring costs of approximately $600,000 were incurred in connection with
the acquisition including relocation and other acquisition-related costs.

INCOME PER COMMON AND COMMON EQUIVALENT SHARE

         Income per common and common equivalent share is computed using the
weighted average number of shares of common stock and common stock equivalents
outstanding during the period.  Common stock equivalents include the number of
shares issuable upon exercise of stock options, less the number of shares that
could have been repurchased with the exercise proceeds using the treasury stock
method.

PRO FORMA PROVISION FOR INCOME TAXES

         Prior to the merger, Advance Geophysical Corporation ("Advance"), a
wholly-owned subsidiary acquired on March 25, 1994, had elected S Corporation
status for federal income tax purposes; therefore, the tax liability associated
with its income was the responsibility of the shareholders.  To reflect the
earnings of Advance on an after-tax basis, an unaudited pro forma provision for
income taxes has been included in the accompanying Consolidated Statements of
Operations for the three months and six months ended December 31, 1993.  This
provision was computed as if Advance were a C Corporation and responsible for
its federal and state income taxes.

</TABLE>


         During the six month period ended December 31, 1993, there were
non-cash investing activities of approximately $1.5 million relating to stock
issued in connection with the purchase of the corporate headquarters.

         During the six month periods ended December 31, 1994 and 1993, there
were non-cash financing activities of $267,000 and $375,000, respectively,
relating to tax benefits received from the exercise of non-qualified stock
options by employees.

CONTINGENCIES

         Under the terms of the MGA acquisition agreement, the Company may be
obligated to make earn-out payments over a period of four years with a net
present value of up to $6.0 million.  The amount of earn-out payments made,
which is dependent upon the operating income of MGA in each of the twelve month
periods ending June 30, 1995 through 1998, may range from zero to approximately
$8.7 million.  Under the terms of the agreement, the Company has the option to
prepay the earn-out payments at any time at their net present value, computed
as defined in the agreement.

         Additionally, in connection with the MGA transaction, the Company
acquired an option to purchase the equity interests of a related party in
exchange for a line of credit guarantee.  The option is exercisable no later
than October 31, 1997 at an exercise price which is based upon the related
party's financial results.  In no event will the net present value of the
option price be less than $8.0 million.

SUBSEQUENT EVENT

         On February 2, 1995 the Company signed a letter of intent to purchase
certain assets of DRD Corporation, of Tulsa, Oklahoma in exchange for cash of
approximately $6.0 million.  The transaction is subject to, among other
conditions, a due-diligence examination by the Company, the signing of a
definitive agreement and final approval of the Board of Directors.  It is
anticipated that the transaction will be consummated in February 1995.  Due to
the significant uncertainties inherent in the due-diligence process, no
assurance can be given as to whether this transaction will be consummated.

            ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

GENERAL

         Management's Discussion and Analysis of Financial Condition and
Results of Operations is the Company's analysis of its financial performance
and of significant trends which may impact future performance.  It should be
read in conjunction with the consolidated financial statements of the Company
and the related notes thereto.  The financial statements for the fiscal 1994
periods presented have been restated to account for the acquisition of
Stratamodel, Inc.  ("Stratamodel") on a pooling-of-interests basis.

         A significant portion of the Company's revenue is derived from sales
into certain geographic or market sectors which, due to regulatory requirements
and other constraints, may have lengthy sales cycles.  Accordingly, the timing
of revenue recognition on these transactions may have a noticeable effect on
the quarter-to-quarter and year-to-year financial performance.


RESULTS OF OPERATIONS

         Total revenues.  Total revenues for the second quarter of fiscal 1995
increased approximately 15% compared to the same quarter in the prior year.
Sales for the first half of fiscal 1995 were up approximately $6.7 million, or
10% over the comparable period in fiscal 1994.  The increase in total revenues
was due to the growth experienced in software maintenance revenues and the
impact of the MGA acquisition.  Decreased domestic spending by customers
combined with continued expansion into developing markets in Europe and Latin
America has resulted in international revenues increasing from 54% of total
revenues for the first six months of fiscal 1994 to 59% for the same period in
fiscal 1995.

         Software product sales.  Software product sales consist of licensing
fees for the Company's proprietary and third party software.  Software product
sales increased approximately $2.8 million and $1.5 million during the second
quarter and first six months of fiscal 1995, respectively, an increase of 16%
and 5% over the comparable periods in fiscal 1994.  The increase was primarily
attributable to the inclusion of several large international orders and
revenues related to MGA's applications.  These increases were somewhat offset
by reduced spending by customers in the domestic market.  Software product
sales as a percentage of total revenues, or software mix, continues to remain a
significant percentage of the Company's revenues.  Management expects this
trend to continue; however, future revenue growth is, in part, dependent on the
Company's ability to bring innovative software products to the market ahead of
its competitors.  The Company intends to release several new software products
during the remainder of fiscal 1995; however, there can be no assurance that
these new products will result in significant revenue growth.

         Hardware product sales.  Hardware product sales relate to the resale
of third party computer hardware.  Hardware product sales decreased
approximately $1.0 million and $300,000 during the second quarter and first six
months of fiscal 1995, respectively, a decrease of 10% and 2% over the
comparable periods in fiscal 1994.  The decreases are primarily a result of
reduced spending by major oil companies in the domestic market.





                                 Page 12 of 18
<PAGE>   13
         Maintenance and other.   Maintenance and other revenues relate to
maintenance and support of the Company's hardware and software products as well
as revenues from other services, including consulting, offered to customers.
Maintenance and other revenues increased approximately $3.8 million and $5.5
million during the second quarter and first six months of fiscal 1995,
respectively, an increase of 40% and 30% over the comparable periods in fiscal
1994.  The increase is a result of increased software maintenance revenues,
which continue to increase as the installed base of applications under service
contracts grow.  This increase was partially offset by decreased processing
services revenues, which result from the Company's decision to discontinue
offering processing services in fiscal 1994.

         Cost of software product sales.  Cost of software product sales, as a
percentage of software product sales, increased from 8% for the second quarter
and 9% for the first six months of fiscal 1994 to 11% and 12%, respectively, in
fiscal 1995.  This increase as a percentage of sales was primarily attributable
to the increase in royalty costs resulting from a significant increase in sales
of third party software applications over the prior fiscal year.  As customers
demand a broader range of applications, including those offered by third party
vendors, royalty costs and the resulting impact on software product margins may
continue.

         Cost of hardware product sales.  Cost of hardware product sales, as a
percentage of hardware product sales, decreased from 84% in the second quarter
of fiscal 1994 to 82% in the current quarter; however, for the six month period
the cost of hardware product sales remained relatively constant from year to
year at 83%.  The quarter to quarter decrease is a result of closing several
large orders with international customers which yielded higher than average
hardware margins.  Although the current quarter's hardware margin was
positively impacted by these orders, management believes price competition in
the computer hardware industry has negatively impacted the hardware product
margins and anticipates lower hardware margins may be realized in the future.
Although hardware has become less profitable as a result of price competition,
the Company will continue to offer hardware to accommodate sales of software
and services to customers who desire comprehensive CAEX solutions.

         Cost of maintenance and other.  Cost of maintenance and other has
decreased as a percentage of the related revenues from 62% in both the second
quarter and the first six months of fiscal 1994 to 58% and 59% in the current
quarter and the first six months of fiscal 1995, respectively.  This decrease
is attributable to the Company's decision to discontinue offering processing
services in fiscal 1994 which resulted in a reduction of the related costs.

         Research and development.  Whereas gross research and development
costs increased approximately 11% from the second quarter in the previous
fiscal year, gross costs for the six month period remained fairly constant.
The majority of the increase over the second quarter in the prior year relates
to the addition of the MGA development function.  The Company believes that
continued investments in research and development are important to its future
growth and competitive position in the marketplace.

         Selling, marketing and administrative.  Selling, marketing and
administrative expenses increased approximately $2.5 million over the second
quarter of fiscal 1994; however, as a percentage of revenue, the costs
increased approximately 1%.  For the six month period selling, marketing and
administrative costs increased approximately $4.3 million over the comparable
period in the prior fiscal year.  The increases in absolute costs relates to





                                 Page 13 of 18
<PAGE>   14
incremental costs associated with the MGA operations and selling costs
associated with expanding the international scope of the sales and distribution
function.

         Merger costs.  Merger costs, which approximate 2% of total revenues
for the first six months of fiscal 1995, consist of accounting, legal and
investment banking costs related to the acquisition of Stratamodel.

         Restructuring and other non-recurring charges.  Restructuring and
other non-recurring charges, which approximate 2% of revenues for the first six
months of fiscal 1995, relate to the Company's restructuring plan which was
designed to eliminate redundancies and consolidate the Stratamodel operations.
Under the plan, the Company accrued approximately $1.2 million of restructuring
charges consisting of approximately $500,000 of severance costs for terminated
employees and approximately $700,000 of lease costs associated with duplicate
facilities.  Management expects this restructuring plan to result in reduced
spending for the Company. Additionally, non-recurring costs of approximately
$600,000 were accrued in connection with the Stratamodel acquisition.  These
non-recurring costs include approximately $400,000 in relocation costs and
approximately $200,000 in other acquisition-related charges.

         Other, net. Other, net increased approximately $287,000 and $763,000
for the second quarter and the first six months of fiscal 1995, respectively,
from the same periods in fiscal 1994.  The fluctuations are primarily
attributable to higher net interest income.  For the six month period, the
increase was partially offset by increased foreign currency losses over the
first six months of fiscal 1994 due to unfavorable fluctuations in currency
exchange rates.

         Taxes.  During the second quarter of fiscal 1995, the effective tax
rate was lower than the statutory rate and higher than the prior year's rate.
The provision increased primarily due to the application of
pooling-of-interests accounting to the acquisition of a Subchapter S
Corporation in fiscal 1994.  This required the results of operations for the
acquired company for periods prior to the merger to be included in income
before income taxes, however the related income tax liability was excluded, as
it was the responsibility of the S Corporation's stockholders.  In the current
quarter the effective rate was less than the statutory rate due mainly to the
recognition of deferred tax benefits.


FINANCIAL CONDITION AND LIQUIDITY

         Cash and cash equivalents decreased approximately $8.0 million from
June 30, 1994.  A substantial amount of this decrease relates to amounts used
in connection with fiscal 1995 acquisitions.  After excluding the effect of
cash utilized for acquisitions during the six month period, cash generated
internally exceeded the cash required to support the Company's operations by
approximately $6.7 million.

         Trade accounts receivable increased by $156,000 due primarily to the
higher revenues recognized in the second quarter of fiscal 1995 as compared to
the fourth quarter of the previous fiscal year.  Management continued its focus
on collection efforts, resulting in a reduction of days sales outstanding
during the quarter from 98 days to 87 days.  Management intends to continue its
focus on maintaining days sales outstanding within these parameters.





                                 Page 14 of 18
<PAGE>   15
         Goodwill increased approximately $11.2 million from the balance at
June 30, 1994.  This amount relates to the MGA acquisition and represents the
cost in excess of fair value of the net assets acquired.  The goodwill recorded
is being amortized on a straight-line basis over a period of eight years.

         The Company's primary internal source of liquidity is cash flow
generated from operations.  External sources of liquidity include debt and
equity financing.  The Company believes funds generated from operations will be
sufficient to meet liquidity requirements in the foreseeable future.  Although
the Company normally covers capital expenditures with funds generated
internally, long-term financing vehicles may be used in connection with
unusually large capital expenditure programs.

         Subsequent to December 31, 1994, the Company signed a letter of intent
related to the acquisition of DRD Corporation which is expected to be accounted
for as a purchase.  Under the current terms of the transaction, management
expects to use approximately $6 million of the Company's cash and cash
equivalents to effect the transaction.  Aside from the planned acquisition,
management regularly evaluates opportunities to acquire or license products,
technologies or businesses complementary to the Company's business.  These
acquisition opportunities, if they arise, may involve the use of cash or,
depending upon the size and terms of the acquisition, may require debt or
equity financing.

         to the Borrower under the Revolving Note.

                  (3)     "Available Amount" shall mean, at any given time, the

         interest are announced.  The Base Rate is setby Lender as a general

         rate, it is not necessarily the lowest or best rate of interest
         actually charged on any loan, and that Lender may make various
         commercial or other loans at rates of interest having no relationship
         to the Base Rate.  If at any time the Base Rate of Lender is no longer

         Termination Date of the Revolving Note, no Interest Period relating to
         a LIBOR Rate Portion for the Term Note shall extend past the

                 authorized to receive such Optional Currency.

                          (C)     If Lender determines in good faith (which
                 determination shall be conclusive) at any time prior to an

                 Currency is not freely transferrable and convertible into
                 Dollars or that it will be illegal or impossible for Lender to
                 fund such portion of the principal amount of the Revolving

         are subject to the execution by Borrower of Lender's standard
         documentation therefor including, without limitation, provisions
         regarding capital adequacy.  The amount drawn or paid under any Letter

                 adoption after the date hereof of any legal requirement, or
                 any change therein after the date hereof, or any change after
                 the date hereof in the interpretation or administration
                 thereof by any governmental authority or (z) compliance by
                 Lender with any request or directive (whether or not having
                 the force of law) of any governmental authority made after the
                 date hereof;

                          (B)     any governmental authority imposes, modifies
                 or deems applicable any reserve (including without limitation,
                 any imposed by the Board of Governors of the United States
                 Federal Reserve System), special deposits or similar
                 requirement against assets of, deposits with, or for the
                 account of, or credit extended by, Lender, or imposes on
                 Lender any other condition affecting or in any way relating to
                 the LIBOR Deposits (to the extent any such action is not taken
                 into account by Lender in determining any LIBOR Rate) or
                 Optional Currency Deposits (to the extent any such action is
                 not taken into account by Lender in determining any Optional
                 Currency Rate);

                          (C)     any of the events set forth or described in
                 the definition of LIBOR Rate or Optional Currency Rate or in
                 this Agreement regarding making it unlawful or impossible for
                 Lender to obtain LIBOR Deposits or Optional Currency Deposits
                 or otherwise to accrue interest hereunder based on the LIBOR
                 Rate or Optional Currency Rate occurs;

                          (D)     Lender accelerates the maturity of either of
                 the Notes pursuant to a right to do so;

                          (E)     Borrower makes any prepayment under the 
                 Notes; or

                          (F)     Borrower fails to obtain an Advance under
                 this Agreement after it has requested an Advance pursuant to
                 Section 1 hereof (unless such failure is a result of Lender's
                 wrongful refusal to make any such Advance);

         and the result of any of the foregoing is to increase the cost to
         Lender of obtaining, establishing, maintaining or paying LIBOR
         Deposits or Optional Currency Deposits or to reduce the amount of any
         sum received, receivable or retainable by Lender under the Notes, this
         Agreement or any other Loan Document by a material amount, then

         Borrower shall pay to Lender such additional amount or amounts as will
         fully compensate Lender for such increased cost or reduction; provided
         however, in the case of any voluntary prepayment by Borrower of any
         LIBOR Rate Portion, the amount of such compensation shall be
         determined as follows:

                 The product obtained by multiplying (i) the amount (if any) by
                 which the LIBOR Rate for such LIBOR Rate Portion exceeds the
                 LIBOR Rate for such LIBOR Rate Portion as of the date of such
                 prepayment for the remaining term of the Interest Period for
                 such LIBOR Rate Portion, times (ii) the amount of such LIBOR
                 Rate Portion, times (iii) a fraction, the numerator of which
                 is the total number of days remaining in the Interest Period
                 relating to such LIBOR Rate Portion as of the date of such
                 prepayment and the denominator of which is 360.

A certificate of Lender claiming compensation under this Section 2(c)(1),
setting forth the additional amount or amounts to be paid to it by Borrower and
accompanied by reasonable verification by Lender of such additional amount
shall be presumptive evidence of the accuracy thereof, absent manifest error.
Any compensation or other payments to be made hereunder by Borrower to Lender
shall be payable by Borrower within sixty (60) days after receipt of such
certificate, shall bear interest at the Default Rate from the date which is
sixty (60) days after such certificate is delivered to Borrower until paid and
shall be secured by the Loan Documents.

                 (2)      If (x) any legal requirement (or any change in the
         interpretation or administration thereof by any governmental
         authority), (y) any compliance by Lender with any request or directive
         of any governmental authority (whether or not having the force of law)
         or (z) any other circumstance whatsoever shall (1) make it illegal or
         impossible (in Lender's good faith judgment) for Lender to borrow the
         LIBOR Deposits or Optional Currency Deposits or to accrue interest
         hereunder based on the LIBOR Rate or the Optional Currency Rate or (2)
         require Lender to repay the LIBOR Deposits or the Optional Currency
         Deposits prior to the originally scheduled repayment date, then (A)
         the LIBOR Rate Portions affected, upon demand by Lender, shall bear
         interest from and after such demand is made as if no LIBOR Rate was in
         effect and the Stated Rate was based on the Base Rate for such LIBOR
         Rate Portions, Borrower shall pay all reasonable costs of Lender
         incurred as a result of such change in the manner of accruing interest
         hereunder and under the Notes and the LIBOR Rate Option

         shall terminate and be of no further force and effect and (B) the
         Optional Currency Portions affected (together with all accrued
         interest thereon) shall be due and payable in full upon demand by
         Lender, Borrower shall pay all reasonable costs of Lender incurred as
         a result of Borrower's payment of such Optional Currency Portion prior
         to its originally scheduled maturity and, at Lender's election,
         Borrower's right to request additional Optional Currency Advances
         under this Agreement and the other Loan Documents shall terminate and
         be of no further force and effect.  A certificate of Lender claiming
         compensation under this Section 2(c)(2), setting forth the amount of
         the reasonable costs of Lender incurred as the result of any such
         change in the manner of accruing interest hereunder or as a result of
         any such payment prior to maturity and accompanied by reasonable
         verification by Lender of the amount of such reasonable cost shall be
         presumptive evidence of the accuracy thereof.  Any compensation or
         other payments to be made hereunder by Borrower to Lender shall be
         payable by Borrower within sixty (60) days after receipt of such
         certificate, shall bear interest at the Default Rate from the date
         which is sixty (60) days after such certificate is delivered to
         Borrower until paid and shall be secured by the Loan Documents.

         (d)     General Provisions.  The following provisions shall apply to
both of the Notes, notwithstanding any provision to the contrary contained in
either of the Notes:

                 (1)      It is the intention of the parties hereto to comply
         with all applicable usury laws; accordingly, it is agreed that
         notwithstanding any provision to the contrary in this Agreement or any
         other Loan Document, no such provision shall require the payment or
         permit the collection of interest in excess of the maximum rate of
         interest permitted by applicable law ("Maximum Rate").  If any excess
         interest in such respect is provided for, or without taking into
         account the provisions of this Section 2(d)(1) shall be adjudicated to
         be so provided for, in this Agreement or in any other Loan Document,
         then, in such event, (i) the provisions of this Section 2(d)(1) shall
         govern and control, (ii) neither Borrower nor its heirs, legal
         representatives, successors or assigns nor  any other party liable for
         the payment of such excess interest shall be obligated to pay the
         amount of such interest to the extent that it is in excess of the
         Maximum Rate, (iii) any such excess which may have been collected
         shall be either applied as a credit against the then unpaid principal
         amount of the Loan  or refunded to Borrower and (iv) the provisions of
         the Loan

         Documents shall be automatically reformed so that the effective rate
         of interest shall be reduced to the Maximum Rate.  Determination of
         the rate of interest under this Agreement and the other Loan Documents
         for the purpose of determining whether the Loan is usurious shall be
         made by amortizing, prorating, allocating and spreading, during the
         time amounts are outstanding under the Loan, all interest at any time
         contracted for, charged or received in connection with the Loan.

                 (2)      Each determination of the amount of interest owing on
         the Loan shall be computed on the basis of actual days elapsed, but
         computed on the basis of a year consisting of 360 days for purposes of
         determining the Stated Rate.  Interest shall accrue from and including
         the day on which any borrowing is made to, but excluding, the day on
         which any amount is repaid to Lender.  Calculation of the Maximum Rate
         shall be based on a year consisting of the number of days actually
         contained in the year in question.

                 (3)      Lender shall determine the interest rates applicable
         to the Loan in accordance with the terms of this Agreement.

                 (4)      The Maximum Rate to be charged or collected pursuant
         to the Loan shall be the applicable indicated rate ceiling as defined
         in TEX. REV. CIV. STAT. ANN. art. 5069-1.04, provided that Lender may
         rely on other applicable laws, including without limitation, the laws
         of the United States, for calculation of the Maximum Rate if the
         application thereof results in a greater Maximum Rate.  The provisions
         of TEX. REV. CIV. STAT. ANN.  art. 5069-15.01, et seq, as may be
         amended, shall not apply to the Loan or any of the Loan Documents.

         (e)     Payment Provisions.  The Notes shall be payable in accordance
with their terms.  Additionally, the following provisions shall apply with
respect to payment of the Notes:

                 (1)      The Base Rate Portion may be prepaid in whole or in
         part, without penalty and without notice at any time.  No prepayments
         prior to the end of the applicable Interest Period shall be permitted
         for any Optional Currency Portion or any LIBOR Rate Portion unless
         Borrower pays the amount called for in Section 2(c)(1) of this
         Agreement.

                 (2)      Each payment payable by the Borrower under the Notes
         (i) denominated in Dollars shall be made in Dollars to the Lender's
         main office in Houston, Texas, U.S.A. in

         immediately available funds, on or prior to 11:00 a.m., Houston,
         Texas, U.S.A. time, on the due day of such payment or, (ii)
         denominated in any Optional Currency shall be made in the Optional
         Currency denominated in the Advance at a depository designated by the
         Lender in the country in which such Optional Currency is legal tender
         on or prior to 11:00 a.m., local time in the location of such
         depository, on the due date of such payment.  If any sum would, but
         for the provisions hereof, become due and payable hereunder on a day
         which is not a Business Day, then such sum shall become due and
         payable on the next succeeding Business Day.

                 (3)      If at any time the Deemed Outstanding Principal
         Amount is greater than the Maximum Amount, then Borrower shall make a
         prepayment on the Revolving Note in an amount sufficient to reduce the
         Deemed Outstanding Principal Amount to an amount not greater than the
         Maximum Amount within thirty (30) days after Lender requests Borrower
         to make such prepayment.  Borrower shall pay prepayments first against
         the Base Rate Portion, second against the Optional Currency Portions
         and third against the LIBOR Rate Portions.

         (f)     Fees.

                 (1)      Borrower has previously paid Lender a commitment fee
         in the amount of $18,750.00 in connection with the increase of the
         Revolving Credit Facility from $10,000,000.00 to $25,000,000.00.

                 (2)      Borrower shall pay Lender a commitment fee in the
         amount of one-fourth percent (1/4%) per annum of the average unused
         portion of the Revolving Credit Facility, payable quarterly in
         arrears.

                 (3)      Borrower shall pay Lender an amendment fee each time
         any of the Loan Documents is amended in the amount (if any) by which
         $2,500.00 exceeds the amount of Lender's legal fees and expenses paid
         by Borrower in connection with the negotiation and preparation of any
         such amendment.  By providing for payment of such fee, Lender is not
         agreeing to amend any of the Loan Documents in any respect.

         Section 3. Representation and Warranties.  The Borrowing Group hereby
represents and warrants to Lender that, as of the date hereof and as of the
date of each advance under the Revolving Credit Facility:

                 other Loan Documents to which any member of the Borrowing
                 Group is a party constitute the valid and binding obligations
                 of such member enforceable against it in accordance with their
                 terms (subject to any applicable bankruptcy, insolvency or
                 other laws generally affecting the enforcement of creditors'
                 rights).

                 other Loan Documents do not violate any provision of the
                 corporate charter or bylaws of any member of the Borrowing
                 Group, or any contract, agreement, law or regulation to which
                 any such member is subject, and the same do not require the

laws and ordinances, including without limitation the Comprehensive
Environmental Response, Compensation and Liability Act, as such laws and
ordinances may relate to any member of the Consolidated Borrowing Group or any
property or operations of any such member unless any such costs or expenses are
incurred by Lender solely as a result of Lender's gross negligence or willful
misconduct.

         (c)     Renewals and Extensions.  All provisions of this Agreement
shall apply with equal force and effect to each and all renewals and
extensions, in whole or in part, of the Notes or the Credit Facilities.

         (d)     No Waiver; Remedies Cumulative.  No course of dealing on the
part of Lender or its officers or employees, or any failure or delay by Lender
with respect to exercising any right, power, or privilege of Lender under this
Agreement or any other Loan Document shall operate as a waiver thereof.  The
rights and remedies of Lender under this Agreement and the other Loan Documents
shall be cumulative and the exercise or partial exercise of any such right or
remedy shall not preclude the exercise of any other right or remedy.

         (e)     Governing Law.  THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
SHALL BE DEEMED TO BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE
WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS FROM TIME TO TIME IN
EFFECT, EXCEPT TO THE EXTENT UNITED STATES FEDERAL LAW PERMITS LENDER TO
CONTRACT FOR, CHARGE OR RECEIVE A GREATER RATE OR AMOUNT OF INTEREST.

         (f)     Invalid Provisions.  In the event any one or more of the
provisions contained in this Agreement or any of the other Loan Documents
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any
other provision of this Agreement or the other Loan Documents.  Furthermore, in
lieu of such invalid, illegal or unenforceable provision, there shall
automatically be added a provision as similar in terms to such invalid, illegal
or unenforceable provision as may be possible and as may be valid, legal and
enforceable.

         (g)     Headings.  The captions, headings and arrangements used in
this Agreement are for convenience only and do not in any way affect, limit,
amplify or modify the terms and provisions hereof.

         (h)     Lender's Benefit.  All conditions to the obligations of Lender
to make advances hereunder are imposed solely and exclusively for the benefit
of Lender and its successors and assigns, as permitted hereunder, and no other
person shall have standing to require satisfaction of such conditions in
accordance with their terms or be entitled to assume that Lender will refuse to
make advances in the absence of strict compliance with any or all of such terms
and any or all of such conditions may be freely waived in whole or in part by
Lender at any time if in its discretion it deems it advisable to do so;
provided, however, this sentence shall not be deemed to reduce or eliminate the
obligations of Lender hereunder.  Borrower is not a joint venturer, agent or
representative of Lender, and Lender shall not be liable to any Person
asserting a claim against Borrower, or against any of the

Collateral.  The rights granted to Lender by Borrower in this Agreement are
granted for the protection of Lender and shall not be construed to be for the
benefit of any Person not a party to this Agreement.

         (i)     Controlling Document.  Should an inconsistency or conflict
exist between the specific terms of this Agreement, and those of the Note or
any of the other Loan Documents, then the relevant terms of this Agreement
shall govern and control.

         (j)     Setoff.  Upon the occurrence and during the continuance of any
Event of Default, Lender is hereby authorized at any time and from time to
time, without notice to Borrower or any other member of the Borrowing Group
(any such notice being expressly waived by Borrower and all other members of
the Borrowing Group), to setoff and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held by Lender to or
for the credit or the account of Borrower and all other members of the
Borrowing Group against any and all of the Obligations, irrespective of whether
or not Lender shall have made any demand under this Agreement or any other Loan
Documents and although such Obligations may be unmatured.  In that connection,
each member of the Borrowing Group hereby grants to Lender a lien on any of
such member's funds which may from time to time be deposited with Lender.  The
rights of Lender under this Section 11(j) are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which Lender
may have hereunder, at law or in equity.

         (k)     Further Assurances; Power of Attorney.  Each member of the
Borrowing Group, upon the request of Lender, shall execute, acknowledge,
deliver and record and/or file such further instruments (including security
agreements and financing statements covering all or portions of the Collateral
specified by Lender) and do such further acts as may be reasonably necessary,
desirable or proper to carry out more effectively the intent and purposes of
the Loan Documents and to subject to the Lender's liens any property intended
by the terms thereof to be covered thereby, including specifically but without
limitation, any renewals, additions, substitutions, replacements, betterments,
or appurtenances to the then  Collateral.  In this connection, each member of
the Borrowing Group does hereby irrevocably constitute and appoint Lender, with
full power of substitution, as its true and lawful attorney-in-fact and agent
with full power and authority to act in its name, place and stead in the
performance of such member's obligations under this Section 11(k), including
without limitation, the execution, acknowledgment, swearing to, delivering,
filing and recording of any instrument or other document, or the taking of any
other action, which Lender deems reasonably necessary, desirable or proper to
carry out more effectively the intents and purposes of this Agreement and the
other Loan Documents.  The power of attorney
<PAGE>   33

Page 33



granted hereby shall be deemed to be coupled with an interest, shall be
irrevocable, shall survive the death, disability, dissolution, liquidation or
other termination of each member of the Borrowing Group, shall be binding on
all heirs, legal representatives, successors and assigns of each member of the
Borrowing Group and shall inure to the benefit of and be enforceable by Lender
and its successors and assigns.  Lender shall not exercise any of its power of
attorney rights hereunder except during the existence of an Event of Default.

         (l)     Recording and Filing.  Borrower shall pay all recording,
filing, rerecording and refiling taxes, fees and other charges incurred in
connection with Lender or Lender's designee recording, filing, rerecording and
refiling of the Loan Documents and all amendments and supplements thereto and
substitutions therefor.

         (m)     Lender's Right to Perform the Obligations of Borrower.

                      (i)         If any member of the Borrowing Group shall
         fail, refuse or neglect to make any payment or perform any act
         required by the Loan Documents, then at any time thereafter, and
         without notice to or demand upon any member of the Borrowing Group and
         without waiving or releasing any other right, remedy or recourse
         Lender may have because of same, Lender may (but shall not be
         obligated to) make such payment or perform such act for the account of
         and at the expense of the Borrowing Group.  If Lender shall elect to
         pay any tax or other imposition or other sums due with reference to
         the Collateral, Lender may do so in reliance on any bill, statement or
         assessment procured from the appropriate governmental authority or
         other issuer thereof without inquiring into the accuracy or validity
         thereof.  Similarly, in making any payments to protect the security
         intended to be created by the Loan Documents, Lender shall not be
         bound to inquire into the validity of any apparent or threatened
         adverse encumbrance before making an advance for the purpose of
         preventing or removing the same.

                      (ii)        The Borrowing Group shall indemnify and
         reimburse Lender for all losses, expenses, damages, claims and causes
         of action, including reasonable attorneys' fees, incurred or accruing
         by reason of any acts performed by Lender pursuant to the provisions
         of this Section 11(m) or by reason of any other provision in the Loan
         Documents or otherwise arising out of in any way relating to the Loan,
         except for those losses, expenses, damages, claims and causes of
         action caused by Lender's willful misconduct or gross negligence.  All
         sums paid by Lender pursuant to this Section 11(m) or such other
         provision of the Loan Documents, and all other sums
<PAGE>   34
Landmark Graphics Corporation
October 31, 1994
Page 34



         expended by Lender to which it shall be entitled to be indemnified or
         reimbursed, together with interest thereon at the Default Rate, shall
         constitute additions to the Obligations, shall be secured by the
         Lender's liens and shall be paid by the Borrowing Group to Lender upon
         demand.  As used herein, the term "Default Rate" shall mean a rate of
         interest per annum equal to the lesser of (A) four percent (4%) above
         the Base Rate as it fluctuates, or (B) the Maximum Rate.

         (n)     Participations and Assignments.  The Lender shall have the
right, subject to the prior written consent of Borrower, to assign its entire
interest in, or to invite any person to participate in portions of, the Loan
and the Loan Documents.

         (o)     Concerning Representations and Warranties.  No investigation
at any time made by or on behalf of the Lender shall diminish its rights to
rely upon the representations and warranties contained herein.  All statements
contained in any certificate or other instrument delivered by the Borrower, any
Subsidiary or other person under or pursuant to this Agreement or in connection
with the transactions contemplated hereby, shall constitute additional
representations and warranties made by the Borrower.  The representations and
warranties contained herein shall be true and correct at all times during the
term hereof including, without limitation, at the time each financial statement
is submitted by Borrower to the Lender and at the time of each advance
hereunder.

         (p)     DTPA Waiver.  The Borrowing Group hereby represents, warrants
and agrees with Lender that (a) the Borrowing Group is not in a significantly
disparate bargaining position, (b) the Borrowing Group is represented by legal
counsel of its choice, in seeking or acquiring goods or services, other than
the purchase or lease of a family residence occupied or to be occupied as the
residence of a member of the Borrowing Group, by a purchase or a lease for a
consideration paid or to be paid that exceeds $500,000.00, (c) this Agreement
is being executed by the Borrowing Group in connection with such purchase or
lease in that the proceeds of the Loan will be used by members of the Borrowing
Group in purchasing Collateral for an aggregate consideration in excess of
$500,000.00, (d) the Borrowing Group, on a consolidated basis, is a business
consumer with assets of $5,000,000 or more according to the most recent
financial statements of members of the Borrowing Group prepared in accordance
with generally accepted accounting principles, (e) the Borrowing Group has

basis and represent the bargained- for agreement of the parties hereto.  THE
BORROWING GROUP HEREBY WAIVES THE PROVISIONS OF THE

         (q)     Final Agreement of the Parties.

                      (i)         THE LOAN DOCUMENTS ARE A WRITTEN LOAN
         AGREEMENT UNDER SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE.

                      (ii)        SUCH WRITTEN LOAN AGREEMENT (BEING ALL OF THE
         LOAN DOCUMENTS) REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES AND
         MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
         SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

                      (iii)       THERE ARE NO UNWRITTEN ORAL AGREEMENTS 
         AMONG THE PARTIES.

         (r)     Joinder by Guarantor.  Each Guarantor is executing this
Agreement and its Specific Guaranty in consideration for Lender's making the
Loan to Borrower.  Each Guarantor, by executing and delivering this Agreement,
its Specific Guaranty and any other Loan Documents that it executes, agrees,
acknowledges, represents and warrants that (i) such Guarantor is a Subsidiary,
(ii) such Guarantor will benefit, directly or indirectly, by the advancement of
funds under the Revolving Note, any advancement of funds under the other Loan
Documents, and the execution of this Agreement and the Second Modification
Agreement and (iii) but for the execution and delivery of this Agreement, the
Guaranty and any other Loan Document executed by Guarantor and Guarantor's
agreement to be bound by the provisions hereof and thereof, Lender would not
have entered into this Agreement and the Second Modification Agreement and
would not have advanced additional proceeds of the Revolving Note to Borrower.
Each Guarantor is joining in the execution of this Agreement to evidence its
agreement to the terms and provisions of this Agreement applicable to it and to
evidence its agreement to cause Borrower to be able to perform its obligations
under this Agreement and the other Loan Documents.

         (s)     Arbitration.

                      (i)         Any controversy or claim between or among the
         parties hereto, including but not limited to those arising out of or
         relating to this Agreement or the Loan Documents, including any claim
         based on or arising from an alleged tort, shall be determined by
         binding arbitration in accordance with the Federal Arbitration Act (or
         if not applicable, the applicable state law), the rules of practice
         and procedure for the arbitration of commercial disputes of Judicial
         Arbitration and Mediation

         Services, Inc. ("JAMS"), and the "special rules" set forth in
         paragraph (2) below.  In the event of any inconsistency, the special
         rules shall control.  Judgment upon any arbitration award may be
         entered in any court having jurisdiction.  Any party to this Agreement
         or other Loan Document may bring an action, including a summary or
         expedited proceeding, to compel arbitration of any controversy or
         claim to which this Agreement or any of the Loan Documents applies in
         any court having jurisdiction over such action.

                      (ii)        The arbitration shall be conducted in
         Houston, Texas, and administered by JAMS, who shall appoint an
         arbitrator; if JAMS is unable or legally precluded from administering
         the arbitration, then the American Arbitration Association shall
         serve.  All arbitration hearings shall be commenced within 90 days of
         the demand for arbitration; further, the arbitrator shall only, upon a
         showing of cause, be permitted to extend the commencement of such
         hearing for up to an additional 60 days.

                      (ii)        Nothing in this Agreement or other Loan
         Document shall be deemed to (i) limit the applicability of any
         otherwise applicable statutes of limitation or repose and any waivers
         contained in this Agreement or the other Loan Documents; or (ii) be a
         waiver by Lender of the protection afforded to it by 12 U.S.C.  Sec.
         91 or any substantially equivalent state law; or (iii) limit the right
         of the Lender hereto (A) to exercise self-help remedies such as (but
         not limited to) setoff, or (B) to foreclose against any real or
         personal property collateral, or (C) to obtain from a court
         provisional or ancillary remedies such as (but not limited to)
         injunctive relief, writ of possession or the appointment of a
         receiver.  Lender may exercise such self-help rights, foreclose upon
         such property, or obtain such provisional or ancillary remedies
         before, during, or after the pendency of any arbitration proceeding
         brought pursuant to this Agreement.  Neither this exercise of
         self-help remedies nor the institution or maintenance of an action for
         foreclosure or provisional or ancillary remedies shall constitute a
         waiver of the right of any party, including the claimant in any such
         action, to arbitrate the merits of the controversy or claim
         occasioning resort to such remedies.

employees of the Company and its Subsidiaries by offering such key employees
performance-based stock incentives and other equity interests in the Company
and other incentive awards that recognize the creation of value for the
stockholders of the Company and promote the Company's long-term growth and
success.  To achieve these purposes, eligible persons may receive stock
options, Stock Appreciation Rights, Restricted Stock, Performance Awards,
performance stock, Dividend Equivalent Rights and any other Awards, or any
combination thereof.

         limitation, such a Change in Control shall be deemed to have occurred
         if (a) any "person," as such term is used in Sections 13(d) and 14(d)
         of the Exchange Act (other than the Company, any trustee or other
         fiduciary holding securities under any employee benefit plan of the
         Company, or any company owned, directly or indirectly, by the
         stockholders of the Company in substantially the same proportions as
         their ownership of stock of the Company), is or becomes the
         "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act),
         directly or indirectly, of securities of the Company representing

         consecutive years, individuals who at the beginning of such period
         constitute the Board cease for any reason to constitute at least a
         majority thereof, unless the election by the Board or the nomination
         for election by the Company's stockholders was approved by a vote of
         at least two-thirds (2/3) of the directors then still in office who
         either were directors at the beginning of the two-year period or whose
         election or nomination for election was previously so approved; (ii)
         the stockholders of the Company approve a merger or consolidation of
         the Company with any other corporation, other than a merger or
         consolidation that would result in the voting securities of the
         Company outstanding immediately prior thereto continuing to represent
         (either by remaining outstanding or by being converted into voting
         securities of the surviving entity) more than eighty percent (80%) of
         the combined voting power of the voting securities of the surviving
         entity outstanding immediately after such merger or consolidation;
         provided, however, that a merger or consolidation effected to
         implement a reorganization or recapitalization of the Company, or a

         "person" acquires more than twenty percent (20%) of the combined
         voting power of the Company's then outstanding securities shall not
         constitute a Change in Control of the Company; or (iii) the

         the Company or an agreement for the sale or disposition by the Company
         of all or substantially all of the Company's assets.

         last for a continuous period of not less than twelve (12) months, as
         determined in the sole and absolute discretion of the Committee.

                 2.9      "Dividend Equivalent Right" shall mean the right of
         the holder thereof to receive credits based on the cash dividends that
         would have been paid on the Shares specified in an Award granting

         SECTION 3.       ADMINISTRATION OF THE PLAN

         interpreted by the Committee.

                 3.2      Awards.  Subject to the provisions of the Plan and
         directions from the Board, the Committee is authorized to:

                          (a)     determine the persons to whom Awards are to
                 be granted;

                          (b)     determine the types and combinations of
                 Awards to be granted, the number of Shares to be covered by
                 the Award, the pricing of the Award, the time or times when

                                      -3-
<PAGE>   4
                          (e)     determine whether, to what extent and under
                 what circumstances to provide loans from the Company to
                 participants to purchase Shares subject to Awards under the
                 Plan, and the terms and conditions of such loans;

                          (f)     rely upon employees of the Company for such
                 clerical and recordkeeping duties as may be necessary in
                 connection with the administration of the Plan; and

                          (g)     make all other determinations and take all
                 other actions necessary or advisable for the administration of
                 the Plan.

                 3.3      Procedures.  A majority of the Committee members
         shall constitute a quorum.  All determinations of the Committee shall
         be made by a majority of its members.  All questions of interpretation
         and application of the Plan or pertaining to any question of fact or
         Award granted hereunder shall be decided by the Committee, whose
         decision shall be final, conclusive and binding upon the Company and
         each other affected party.

         SECTION 4.       SHARES SUBJECT TO PLAN

                 4.1      Limitations.  The maximum number of Shares that may
         be issued with respect to Awards under the Plan shall not exceed
         1,000,000 unless such maximum shall be increased or decreased by
         reason of changes in capitalization of the Company as hereinafter
         provided.  The Shares issued pursuant to the Plan may be authorized
         but unissued Shares, or may be issued Shares which have been
         reacquired by the Company.

                 4.2      Changes.  To the extent that any Award under the
         Plan, or any stock option or performance award granted under any prior
         incentive plan of the Company, shall be forfeited, shall expire or
         shall be cancelled, in whole or in part, then the number of Shares
         covered by the Award or stock option so forfeited, expired or
         cancelled may again be awarded pursuant to the provisions of the Plan.
         In the event that Shares are delivered to the Company in full or
         partial payment of the exercise price for the exercise of a stock
         option granted under the Plan or any prior incentive plan of the
         Company, the number of Shares available for future Awards under the
         Plan shall be reduced only by the net number of Shares issued upon the
         exercise of the option.  Awards that may be satisfied either by the
         issuance of Shares or by cash or other consideration shall, until the
         form of consideration to be paid is finally determined, be counted
         against the maximum number of Shares that may be issued under the
         Plan. If the Award is ultimately satisfied by the payment of
         consideration other than Shares, as, for example, a stock option
         granted in tandem with a Stock Appreciation Right that is settled by a
         cash payment of the stock appreciation, such Shares may again be made
         the subject of an Award under the Plan.  Awards will not reduce the
         number of Shares that may be issued pursuant to the Plan if the
         settlement of the Award will not require the issuance of Shares, as,
         for example, a Stock Appreciation Right that can be satisfied only by
         the payment of cash.

         SECTION 5.       ELIGIBILITY

         Eligibility for participation in the Plan shall be confined to those
persons who are employed by the Company or a Subsidiary, and who are either
officers of the Company or a Subsidiary, or who are in managerial or other key
positions within the Company or a Subsidiary.  In making any determination as
to persons to whom Awards shall be granted, the type of Award, and/or the
number of Shares to be covered by the Award, the Committee shall consider the
position and responsibilities of the person, his or her importance to the
Company, the duties of such person, his or her past, present and potential
contributions to the growth and success of the Company, and such other factors
as the Committee shall deem relevant in connection with accomplishing the
purposes of the Plan.

         SECTION 6.       STOCK OPTIONS

                 6.1      Grants.  The Committee may grant stock options alone
         or in addition to other Awards granted under the Plan to any eligible
         officer or other key employee.  Each person so selected shall be
         offered an option to purchase the number of Shares determined by the
         Committee.  The Committee shall





                                      -4-
<PAGE>   5
         specify whether such option is an Incentive Stock Option or
         Non-Qualified Stock Option and any other terms or conditions relating
         to such Award.  To the extent that any stock option does not qualify
         as an Incentive Stock Option (whether because of its provisions or the
         time or manner of its exercise or otherwise), such stock option or the
         portion thereof which does not qualify shall constitute a separate
         Non-Qualified Stock Option.  Each such person so selected shall have a
         reasonable period of time within which to accept or reject the offered
         option.  Failure to accept within the period so fixed by the Committee
         may be treated as a rejection.  Each person who accepts an option
         shall enter into a written agreement with the Company, in such form as
         the Committee may prescribe, setting forth the terms and conditions of
         the option, consistent with the provisions of the Plan.  The Optionee
         and the Company shall enter into option agreements for Incentive Stock
         Options and Non-Qualified Stock Options.  At any time and from time to
         time, the Optionee and the Company may agree to modify an option
         agreement so that an Incentive Stock Option may be converted to a
         Non-Qualified Stock Option.

                 The Committee may require that an Optionee meet certain
         conditions before the option or a portion thereof may vest or be
         exercised, as, for example, that the Optionee remain in the employ of
         the Company or a Subsidiary for a stated period or periods of time
         before the option, or stated portions thereof, may vest or be
         exercised.

                 6.2      Option Price.  The option exercise price of the
         Shares covered by each stock option shall be determined by the
         Committee; provided, however, that the option exercise price of an
         Incentive Stock Option shall not be less than one hundred percent
         (100%) of the Fair Market Value of Shares on the date of the grant of
         such Incentive Stock Option.

                 6.3      Incentive Stock Options Limitations.

                          (a)     In no event shall any person be granted
                 Incentive Stock Options to the extent that the Shares covered
                 by any Incentive Stock Options (and any incentive stock
                 options granted under any other plans of the Company and its
                 Subsidiaries) that may be exercised for the first time by such
                 person in any calendar year have an aggregate Fair Market
                 Value in excess of $100,000.  For this purpose, the Fair
                 Market Value of the Shares shall be determined as of the dates
                 on which the Incentive Stock Options are granted.  It is
                 intended that the limitation on Incentive Stock Options
                 provided in this Subsection 6.3(a) be the maximum limitation
                 on options which may be considered Incentive Stock Options
                 under the Code.

                          (b)     Notwithstanding anything herein to the
                 contrary, in no event shall any employee owning more than ten
                 percent (10%) of the total combined voting power of the
                 Company or any Subsidiary be granted an Incentive Stock Option
                 hereunder unless the option exercise price shall be at least
                 one hundred ten percent (110%) of the Fair Market Value of the
                 Shares subject to such Incentive Stock Option at the time that
                 the Incentive Stock Option is granted and  the term of such
                 Incentive Stock Option shall not exceed five (5) years.

                 6.4      Option Term.  Subject to Subsection 6.3(b) hereof,
         the term of a stock option shall be for such period of months or years
         from the date of its grant as may be determined by the Committee;
         provided, however, that no Incentive Stock Option shall be exercisable
         later than ten (10) years from the date of its grant.  Furthermore, no
         Incentive Stock Option may be exercised unless, at the time of such
         exercise, the Optionee is, and has been continuously since the date of
         grant of his or her Incentive Stock Option, employed by the Company or
         a Subsidiary, except that:

                          (a)     An Incentive Stock Option may, to the extent
                 vested, be exercised within the period of three months after
                 the date the Participant ceases to be an employee of the
                 Company (or within such lesser period as may be specified in
                 the applicable option agreement), provided that the option
                 agreement may designate a longer exercise period and that the
                 exercise after such three-month period shall be treated as the
                 exercise of a Non-Qualified Stock Option under the Plan;





                                      -5-
<PAGE>   6
                          (b)     If the Optionee dies while in the employ of
                 the Company or a Subsidiary, or within three months after the
                 Optionee ceases to be such an employee, the Incentive Stock
                 Option may, to the extent vested, be exercised by the
                 Optionee's Designated Beneficiary within the period of one
                 year after the date of death (or within such lesser period as
                 may be specified in the applicable option agreement); and

                          (c)     If the Optionee ceases to be an employee of
                 the Company or a Subsidiary by reason of the Optionee's
                 Disability, the Incentive Stock Option may be exercised within
                 the period of one year after the date of Disability (or within
                 such lesser period as may be specified in the applicable
                 option agreement).

                 6.5      Vesting of Stock Options.

                          (a)     Each stock option granted hereunder may only
                 be exercised to the extent that the Optionee is vested in such
                 option.  Each stock option shall vest separately in accordance
                 with the option vesting schedule, if any, determined by the
                 Committee in its sole discretion, which will be incorporated
                 in the stock option agreement entered into between the Company
                 and each Optionee.  The option vesting schedule will be
                 accelerated if, in the sole discretion of the Committee, the
                 Committee determines that acceleration of the option vesting
                 schedule would be desirable for the Company.

                          (b)     In the event of the dissolution or
                 liquidation of the Company, each stock option granted under
                 the Plan shall terminate as of a date to be fixed by the
                 Board; provided, however, that not less than thirty (30) days'
                 written notice of the date so fixed shall be given to each
                 Optionee and each such Optionee shall be fully vested in and
                 shall have the right during such period to exercise the
                 option, even though such option would not otherwise be
                 exercisable under the option vesting schedule.  At the end of
                 such period, any unexercised option shall terminate and be of
                 no further effect.

                          (c)     In the event of a Reorganization (as defined
                 in Section 2.3 hereof):

                                  (1)      If there is no plan or agreement
                          respecting the Reorganization, or if such plan or
                          agreement does not specifically provide for the
                          change, conversion or exchange of the Shares under
                          outstanding and unexercised stock options for other
                          securities, then the provisions of Subsection 6.5(b)
                          shall apply as if the Company had dissolved or been
                          liquidated on the effective date of the
                          Reorganization; or

                                  (2)      If there is a plan or agreement
                          respecting the Reorganization, and if such plan or
                          agreement specifically provides for the change,
                          conversion or exchange of the Shares under
                          outstanding and unexercised stock options for
                          securities of another corporation, then the Board
                          shall adjust the Shares under such outstanding and
                          unexercised stock options (and shall adjust the
                          Shares remaining under the Plan which are then
                          available to be awarded under the Plan, if such plan
                          or agreement makes no specific provision therefor) in
                          a manner not inconsistent with the provisions of such
                          plan or agreement for the adjustment, change,
                          conversion or exchange of such Shares and such
                          options.

                          (d)     In the event of a Change in Control of the
                 Company, all stock options and any associated Stock
                 Appreciation Rights shall become fully vested and immediately
                 exercisable and the vesting of all performance-based stock
                 options shall be determined as if the performance period or
                 cycle applicable to such stock options had ended immediately
                 upon such Change in Control; provided, however, that if in the
                 opinion of counsel to the Company the immediate exercisability
                 of options when taken into consideration with all other
                 "parachute payments" as defined in Section 280G of the Code,
                 as amended, would result in an "excess parachute payment" as
                 defined in such section as well as an excise tax imposed by
                 Section 4999 of the Code, such options and any





                                      -6-
<PAGE>   7
                 associated Stock Appreciation Rights shall become fully vested
                 and immediately exercisable, except as and to the extent
                 the Committee, in its sole discretion, shall otherwise
                 determine, and which determination by the Committee shall
                 be based solely upon maximizing the after-tax benefits to be   
                 received by any such Optionee.

                          6.6     Exercise of Stock Options.

                          (a)     Stock options may be exercised as to Shares
                 only in amounts and at intervals of time specified in the
                 written option agreement between the Company and the Optionee.
                 Each exercise of a stock option, or any part thereof, shall be
                 evidenced by a notice in writing to the Company.  The purchase
                 price of the Shares as to which an option shall be exercised
                 shall be paid in full at the time of exercise, and may be paid
                 to the Company either:

                                  (1)      in cash (including check, bank draft
                          or money order);

                                  (2)      by the delivery of Shares having a
                          Fair Market Value equal to the aggregate option price;

                                  (3)      by a combination of cash and Shares;
                          or

                                  (4)      by other consideration deemed
                          acceptable by the Committee in its sole discretion.

                          (b)     If an Optionee delivers Shares (including
                 Shares of Restricted Stock) already owned by him or her in
                 full or partial payment of the exercise price for any stock
                 option granted under the Plan or any prior incentive plan of
                 the Company, or if the Optionee elects to have the Company
                 retain that number of Shares out of the Shares being acquired
                 through the exercise of the option having a Fair Market Value
                 equal to the exercise price of the stock option being
                 exercised, the Committee may authorize the automatic grant of
                 a new option (a "Reload Option") for that number of Shares as
                 shall equal the number of already owned Shares surrendered
                 (including Shares of Restricted Stock) or newly acquired
                 Shares being retained in payment of the option exercise price
                 of the underlying stock option being exercised.  The grant of
                 a Reload Option will become effective upon the exercise of the
                 underlying stock option.  The option exercise price of the
                 Reload Option shall be the Fair Market Value of a Share on the
                 effective date of the grant of the Reload Option.  Each Reload
                 Option shall be exercisable no earlier than six (6) months
                 from the date of its grant and no later than the time when the
                 underlying stock option being exercised could be last
                 exercised.  The Committee may also specify additional terms,
                 conditions and restrictions for the Reload Option and the
                 Shares to be acquired upon the exercise thereof.

                          (c)     The amount, as determined by the Committee,
                 of any federal, state or local tax required to be withheld by
                 the Company due to the exercise of a stock option shall be
                 satisfied, at the election of the Optionee, either (a) by
                 payment by the Optionee to the Company of the amount of such
                 withholding obligation in cash or other consideration
                 acceptable to the Committee in its sole discretion (the
                 "Non-Share Method") or (b) through either the retention by the
                 Company of a number of Shares out of the Shares being acquired
                 through the exercise of the option or the delivery of already
                 owned Shares having a Fair Market Value equal to the amount of
                 the withholding obligation (the "Share Retention Method").  If
                 an Optionee elects to use the Share Retention Method in full
                 or partial satisfaction for any tax liability resulting from
                 the exercise of a stock option, the Committee may authorize
                 the grant of a Reload Option for that number of Shares as
                 shall equal the number of Shares used to satisfy the tax
                 liabilities of the stock option being exercised on the price
                 and terms set forth in Subsection (b) above.  The cash payment
                 or the amount equal to the Fair Market Value of the Shares so
                 withheld, as the case may be, shall be remitted by the Company
                 to the appropriate taxing authorities.  The Committee shall
                 determine the time and manner in which an Optionee may elect
                 to satisfy a withholding obligation by either the Non-Share
                 Method or the Share Retention Method.

<PAGE>   8
                          (d)     An Optionee shall not have any of the rights
                 of a stockholder of the Company with respect to the Shares
                 covered by a stock option except to the extent that one or
                 more certificates representing such Shares shall have been
                 delivered to the Optionee, or the Optionee has been determined
                 to be a stockholder of record by the Company's transfer agent,
                 upon due exercise of the option.

                 6.7      Date of a Stock Option Grant.  The granting of a
         stock option shall take place only upon the execution and delivery by
         the Company and an optionee of an option agreement.  Neither any
         action taken by the Board nor anything contained in the Plan or in any
         resolution adopted or to be adopted by the Board or the stockholders
         of the Company shall constitute the granting of a stock option under
         the Plan.

         SECTION 7.       STOCK APPRECIATION RIGHTS

                 7.1      Grants.  The Committee may grant to any eligible
         employee either Non-Tandem Stock Appreciation Rights or Tandem Stock
         Appreciation Rights.  Stock Appreciation Rights shall be subject to
         such terms and conditions as the Committee shall impose.  The grant of
         the Stock Appreciation Right may provide that the holder may be paid
         for the value of the Stock Appreciation Right either in cash or in
         Shares, or a combination thereof, at the discretion of the Committee.
         In the event of the exercise of a Stock Appreciation Right payable in
         Shares, the holder of the Stock Appreciation Right shall receive that
         number of whole Shares of stock of the Company having an aggregate
         Fair Market Value on the date of exercise equal to the value obtained
         by multiplying (i) either (a) in the case of a Tandem Stock
         Appreciation Right, the difference between the Fair Market Value of a
         Share on the date of exercise over the per share exercise price of the
         related option, or (b) in the case of a Non-Tandem Stock Appreciation
         Right, the difference between the Fair Market Value of a Share on the
         date of exercise over the Fair Market Value on the date of the grant
         by (ii) the number of Shares as to which the Stock Appreciation Right
         is exercised.  However, notwithstanding the foregoing, the Committee,
         in its sole discretion, may place a ceiling on the amount payable upon
         exercise of a Stock Appreciation Right, but any such limitation shall
         be specified at the time that the Stock Appreciation Right is granted.

                 7.2      Exercisability.  A Tandem Stock Appreciation Right
         may be granted at the time of the grant of the related stock option
         or, if the related stock option is a Non-Qualified Stock Option, at
         any time thereafter during the term of the stock option.  A Tandem
         Stock Appreciation Right granted in connection with an Incentive Stock
         Option (i) may be exercised at, and only at, the times and to the
         extent the related Incentive Stock Option is exercisable, (ii) expires
         upon the termination of the related Incentive Stock Option, (iii) may
         not exceed 100% of the difference between the exercise price of the
         related Incentive Stock Option and the market price of the Shares
         subject to the related Incentive Stock Option at the time the Tandem
         Stock Appreciation Right is exercised and (iv) may be exercised at,
         and only at, such times as the market price of the Shares subject to
         the related Incentive Stock Option exceeds the exercise price of the
         related Incentive Stock Option.  The Tandem Stock Appreciation Right
         may be transferred at, and only at, the times and to the extent the
         related stock option is transferable.  If a Tandem Stock Appreciation
         Right is granted, there shall be surrendered and cancelled from the
         related option at the time of exercise of the Tandem Stock
         Appreciation Right, in lieu of exercise under the related option, that
         number of Shares as shall equal the number of Shares as to which the
         Tandem Stock Appreciation Right shall have been exercised.

                 7.3      Certain Limitations on Non-Tandem Stock Appreciation
         Rights.  A Non-Tandem Stock Appreciation Right will be exercisable as
         provided by the Committee and will have such other terms and
         conditions as the Committee may determine.  A Non-Tandem Stock
         Appreciation Right is subject to acceleration of vesting or immediate
         termination in certain circumstances in the same manner as stock
         options pursuant to Subsections 6.4 and 6.5 of the Plan.

                 7.4      Limited Stock Appreciation Rights.  The Committee is
         also authorized to grant "limited stock appreciation rights," either
         as Tandem Stock Appreciation Rights or Non-Tandem Stock Appreciation
         Rights.  Limited stock appreciation rights would become exercisable
         only upon the occurrence of a Change in Control or such other event as
         the Committee may designate at the time of grant or thereafter.

         SECTION 8.       RESTRICTED STOCK

                 8.1      Grants.  The Committee may grant Awards of Restricted
         Stock for no cash consideration, for such minimum consideration as may
         be required by applicable law, or for such other consideration as may
         be specified by the grant.  The terms and conditions of the Restricted
         Stock shall be specified by the grant agreement.  The Committee, in
         its sole discretion, may specify any particular rights which the
         person to whom an Award of Restricted Stock is made shall have in the
         Restricted Stock during the restriction period and the restrictions
         applicable to the particular Award, the vesting schedule (which may be
         based on service, performance or other factors) and rights to
         acceleration of vesting (including, without limitation, whether
         non-vested Shares are forfeited or vested upon termination of
         employment).  Further, the Committee may award performance-based
         Restricted Stock by conditioning the grant, or vesting or such other
         factors, such as the release, expiration or lapse of restrictions upon
         any such Award (including the acceleration of any such conditions or
         terms) of such Restricted Stock upon the attainment of specified
         performance goals or such other factors as the Committee may
         determine.  The Committee shall also determine when the restrictions
         shall lapse or expire and the conditions, if any, under which the
         Restricted Stock will be forfeited or sold back to the Company. Each
         Award of Restricted Stock may have different restrictions and
         conditions.  The Committee, in its discretion, may prospectively
         change the restriction period and the restrictions applicable to any
         particular Award of Restricted Stock.  Unless otherwise set forth in
         the Plan, Restricted Stock may not be disposed of by the recipient
         until the restrictions specified in the Award expire.

                 8.2      Awards and Certificates.  Any Restricted Stock issued
         hereunder may be evidenced in such manner as the Committee, in its
         sole discretion, shall deem appropriate including, without limitation,
         book-entry registration or issuance of a stock certificate or
         certificates.  In the event any stock certificate is issued in respect
         of Shares of Restricted Stock awarded hereunder, such certificate
         shall bear an appropriate legend with respect to the restrictions
         applicable to such Award.  The Company may retain, at its option, the
         physical custody of any stock certificate representing any awards of
         Restricted Stock during the restriction period or require that the
         Restricted Stock be placed in escrow or trust, along with a stock
         power endorsed in blank, until all restrictions are removed or expire.

         SECTION 9.       PERFORMANCE AWARDS

                 9.1      Grants.  A Performance Award may consist of either or
         both, as the Committee may determine, of (i) "Performance Shares" or
         the right to receive Shares, Restricted Stock or cash of an equivalent
         value, or any combination thereof as the Committee may determine, or
         (ii) "Performance Units," or the right to receive a fixed dollar
         amount payable in cash, Common Stock, Restricted Stock or any
         combination thereof, as the Committee may determine.  The Committee
         may grant Performance Awards to any eligible employee, for no cash
         consideration, for such minimum consideration as may be required by
         applicable law or for such other consideration as may be specified at
         the time of the grant.  The terms and conditions of Performance Awards
         shall be specified at the time of the grant and may include provisions
         establishing the performance period, the performance criteria to be
         achieved during a performance period, the criteria used to determine
         vesting (including the acceleration thereof), whether Performance
         Awards are forfeited or vest upon termination of employment during a
         performance period and the maximum or minimum settlement values.  Each
         Performance Award shall have its own terms and conditions, which shall
         be determined in the discretion of the Committee.  If the Committee
         determines, in its sole discretion, that the established performance
         measures or objectives are no longer suitable because of a change in
         the Company's business, operations, corporate structure or for other
         reasons that the Committee deems satisfactory, the Committee may
         modify the performance measures or objectives and/or the performance
         period.

                 9.2      Terms and Conditions.  Performance Awards may be
         valued by reference to the Fair Market Value of a Share or according
         to any formula or method deemed appropriate by the Committee, in its
         sole discretion, including, but not limited to, achievement of
         specific financial, production, sales, cost or earnings performance
         objectives that the Committee believes to be relevant to the Company's
         business and for remaining in the employ of the Company for a
         specified period of time, or the Company's





                                      -9-
<PAGE>   10
         performance or the performance of its Common Stock measured against
         the performance of the market, the Company's industry segment or its
         direct competitors.  Performance Awards may be paid in cash, Shares
         (including Restricted Stock) or other consideration, or any
         combination thereof.  If payable in Shares, the consideration for the
         issuance of the Shares may be the achievement of the performance
         objective established at the time of the grant of the Performance
         Award.  Performance Awards may be payable in a single payment or in
         installments and may be payable at a specified date or dates or upon
         attaining the performance objective, all at the Committee's
         discretion.  The extent to which any applicable performance objective
         has been achieved shall be conclusively determined by the Committee.

         SECTION 10.        DIVIDEND EQUIVALENT RIGHTS

         The Committee may grant a Dividend Equivalent Right, either as a
component of another Award or as a separate Award, and, in general, each such
holder of a Dividend Equivalent Right that is outstanding on a dividend record
date for the Company's Common Stock shall be credited with an amount equal to
the cash or stock dividends or other distributions that would have been
received had the Shares covered by the Award been issued and outstanding on the
dividend record date.  The terms and conditions of the Dividend Equivalent
Right shall be specified by the grant.  Dividend equivalents credited to the
holder of a Dividend Equivalent Right may be paid currently or may be deemed to
be reinvested in additional Shares (which may thereafter accrue additional
Dividend Equivalent Rights).  Any such reinvestment shall be at the Fair Market
Value at the time thereof.  Dividend Equivalent Rights may be settled in cash
or Shares, or a combination thereof, in a single payment or in installments.  A
Dividend Equivalent Right granted as a component of another Award may provide
that such Dividend Equivalent Right shall be settled upon exercise, settlement
or payment for or lapse of restrictions on such other Award, and that such
Dividend Equivalent Right shall expire or be forfeited or annulled under the
same conditions as such other Award.  A Dividend Equivalent Right granted as a
component of another Award may also contain terms and conditions different from
such other Award.

         SECTION 11.        OTHER AWARDS

         The Committee may grant to any eligible employee other forms of Awards
based upon, payable in or otherwise related to, in whole or in part, Shares, if
the Committee, in its sole discretion, determines that such other form of Award
is consistent with the purposes and restrictions of the Plan.  The terms and
conditions of such other form of Award shall be specified by the grant,
including, but not limited to, the price, if any, and the vesting schedule, if
any.  Such Awards may be granted for no cash consideration, for such minimum
consideration as may be required by applicable law or for such other
consideration as may be specified by the grant.

         SECTION 12.        COMPLIANCE WITH SECURITIES AND OTHER LAWS

         In no event shall the Company be required to sell or issue Shares
under any Award if the sale or issuance thereof would constitute a violation of
applicable federal or state securities laws or regulations or a violation of
any other law or regulation of any governmental or regulatory agency or
authority or any national securities exchange.  As a condition to any sale or
issuance of Shares, the Company may place legends on Shares, issue stop
transfer orders and require such agreements or undertakings as the Company may
deem necessary or advisable to assure compliance with any such laws or
regulations, including, if the Company or its counsel deems it appropriate,
representations from the person to whom an Award is granted that he or she is
acquiring the Shares solely for investment and not with a view to distribution
and that no distribution of the Shares will be made unless registered pursuant
to applicable federal and state securities laws, or in the opinion of counsel
of the Company, such registration is unnecessary.

         SECTION 13.        ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR
                            REORGANIZATION

         The value of an Award in Shares shall be adjusted from time to time as
follows:

                 (a)        Subject to any required action by stockholders, the
         number of Shares covered by each outstanding Award, and the exercise
         price, shall be proportionately adjusted for any increase or decrease
         in the number of issued Shares of the Company resulting from a
         subdivision or consolidation of Shares or





                                      -10-
<PAGE>   11
         the payment of a stock dividend (but only in Shares) or any other
         increase or decrease in the number of Shares effected without receipt
         of consideration by the Company.

                 (b)        Subject to any required action by stockholders, if
         the Company shall be the surviving corporation in any Reorganization,
         merger or consolidation, each outstanding Award shall pertain to and
         apply to the securities to which a holder of the number of Shares
         subject to the Award would have been entitled, and if a plan or
         agreement reflecting any such event is in effect that specifically
         provides for the change, conversion or exchange of Shares, then any
         adjustment to Shares relating to an Award hereunder shall not be
         inconsistent with the terms of any such plan or agreement.

                 (c)        In the event of a change in the Shares of the
         Company as presently constituted, which is limited to a change of par
         value into the same number of Shares with a different par value or
         without par value, the Shares resulting from any such change shall be
         deemed to be the Shares within the meaning of the Plan.

                 To the extent that the foregoing adjustments relate to stock
         or securities of the Company, such adjustments shall be made by the
         Board, whose determination shall be final, binding and conclusive.

                 Except as hereinbefore expressly provided in the Plan, any
         person to whom an Award is granted shall have no rights by reason of
         any subdivision or consolidation of stock of any class or the payment
         of any stock dividend or any other increase or decrease in the number
         of shares of stock of any class or by reason of any dissolution,
         liquidation, reorganization, merger or consolidation or spinoff of
         assets or stock of another corporation, and any issue by the Company
         of shares of stock of any class, or securities convertible into shares
         of stock of any class, shall not affect, and no adjustment by reason
         thereof shall be made with respect to, the number or exercise price of
         Shares subject to an Award.

                 The grant of an Award pursuant to the Plan shall not affect in
         any way the right or power of the Company to make adjustments,
         reclassifications, Reorganizations or changes of its capital or
         business structure or to merge or to consolidate or to dissolve,
         liquidate or sell or transfer all or any part of its business or
         assets.

         SECTION 14.        AMENDMENT OR TERMINATION OF THE PLAN

         14.1    Amendment of the Plan.  Notwithstanding anything contained in
the Plan to the contrary, all provisions of the Plan may at any time or from
time to time be modified or amended by the Board; provided, however, that no
Award at any time outstanding under the Plan may be modified, impaired or
cancelled adversely to the holder of the Award without the consent of such
holder; and provided, further, that the Plan may not be amended without
approval by the holders of a majority of the Shares of the Company represented
and voted at a meeting of the stockholders (a) to increase the maximum number
of Shares subject to the Plan, (b) to materially modify the requirements as to
eligibility for participation in the Plan, (c) to decrease the minimum exercise
price for options, (d) to otherwise materially increase the benefits accruing
to persons to whom Awards may be made under the Plan, as amended, or (e) if
such approval is otherwise necessary, to comply with Rule 16b-3 promulgated
under the Exchange Act, as amended, or to comply with any other applicable
laws, regulations or listing requirements, or to qualify for an exemption or
characterization that is deemed desirable by the Board.

         14.2    Termination of the Plan.  The Board may suspend or terminate
the Plan at any time, and such suspension or termination may be retroactive or
prospective.  However, no Award may be granted on or after the tenth
anniversary of the adoption of the Plan.  Termination of the Plan shall not
impair or affect any Award previously granted hereunder and the rights of the
holder of the Award shall remain in effect until the Award has been exercised
in its entirety or has expired or otherwise has been terminated by the terms of
such Award.





                                      -11-
<PAGE>   12
         SECTION 15.        AMENDMENTS AND ADJUSTMENTS TO AWARDS

         The Committee may amend, modify or terminate any outstanding Award
with the Participant's consent at any time prior to payment or exercise in any
manner not inconsistent with the terms of the Plan, including, without
limitation, (i) to change the date or dates as of which (A) an option becomes
exercisable or (B) a performance-based Award is deemed earned, (ii) to amend
the terms of any outstanding Award to provide an exercise price per share which
is higher or lower than the then current exercise price per share of such
outstanding Award or (iii) to cancel an Award and grant a new Award in
substitution therefor under such different terms and conditions as it
determines in its sole and complete discretion to be appropriate including, but
not limited to, having an exercise price per share which may be higher or lower
than the exercise price per share of the cancelled Award.  The Committee is
also authorized to make adjustments in the terms and conditions of, and the
criteria included in, Awards in recognition of unusual or nonrecurring events
(including, without limitation, the events described in Section 13 hereof)
affecting the Company, or the financial statements of the Company or any
Affiliate, or of changes in applicable laws, regulations or accounting
principles, whenever the Committee determines that such adjustments are
appropriate in order to prevent reduction or enlargement of the benefits or
potential benefits intended to be made available under the Plan.  Any provision
of the Plan or any agreement regarding an Award to the contrary
notwithstanding, the Committee may cause any Award granted to be cancelled in
consideration of a cash payment or alternative Award made to the holder of such
cancelled Award equal in value to the Fair Market Value of such cancelled
Award.  The determinations of value under this Section 15 shall be made by the
Committee in its sole discretion.

         SECTION 16.        GENERAL PROVISIONS

         16.1    No Limit on Other Compensation Arrangements.  Nothing
contained in the Plan shall prevent the Company from adopting or continuing in
effect other compensation arrangements, and such arrangements may be either
generally applicable or applicable only in specific cases.

         16.2    No Right to Employment.  Nothing in the Plan or in any Award,
nor the grant of any Award, shall confer upon or be construed as giving any
recipient of an Award any right to remain in the employ of the Company.
Further, the Company may at any time dismiss a participant in the Plan from
employment, free from any liability or any claim under the Plan, unless
otherwise expressly provided in the Plan or in any Award agreement.  No
employee, participant or other person shall have any claim to be granted any
Award, and there is no obligation for uniformity or treatment of employees,
participants or holders or beneficiaries of Awards.

         16.3    GOVERNING LAW.  THE VALIDITY, CONSTRUCTION AND EFFECT OF THE
PLAN AND ANY RULES AND REGULATIONS RELATING TO THE PLAN SHALL BE DETERMINED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

         16.4    Severability.  If any provision of the Plan or any Award is or
becomes or is deemed to be invalid, illegal or unenforceable in any
jurisdiction or as to any person or Award, or would disqualify the Plan or any
Award under any law deemed applicable by the Committee, such provision shall be
construed or deemed amended to conform to applicable laws, or if it cannot be
construed or deemed amended without, in the sole determination of the
Committee, materially altering the intent of the Plan or the Award, such
provision shall be stricken as to such jurisdiction, person or Award and the
remainder of the Plan and any such Award shall remain in full force and effect.

         16.5    No Fractional Shares.  No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities or other property shall be paid or transferred
in lieu of any fractional Shares or whether such fractional Shares or any
rights thereto shall be cancelled, terminated or otherwise eliminated.

         16.6    Headings.  Headings are given to the Subsections of the Plan
solely as a convenience to facilitate reference.  Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.

         16.7    Effective Date.  The Plan shall be effective as of the date of
its approval by the holders of a majority of the Shares of the Company
represented and voting at the next Annual Meeting of Stockholders.  If the





                                      -12-
<PAGE>   13
Plan is not approved by the stockholders at the 1994 Annual Meeting, after such
date, the Plan and all Awards granted hereunder, if any, shall be void.

         16.8    Non-Transferability of Awards.  Awards shall not be
transferable otherwise than by will or the laws of descent and distribution,
and Awards may be exercised, during the lifetime of the holder, only by the
holder; provided, however, that with the approval of the Committee, Awards
other than Incentive Stock Options may be transferred as directed under a
qualified domestic relations order.   Any attempted assignment, transfer,
pledge, hypothecation or other disposition of an Award contrary to the
provisions hereof, or the levy of any execution, attachment or similar process
upon an Award shall be null and void and without effect.

         SECTION 17.        NAMED EXECUTIVE OFFICERS

         17.1    Applicability of Section 17.   The provisions of this Section
17 shall apply only to those executive officers (i) whose compensation is
required to be reported in the Company's proxy statement pursuant to Item
402(a)(3)(i) and (ii) of Regulation S-K under the general rules and regulations
under the Exchange Act, as amended, and (ii) whose total compensation,
including estimated Awards, is determined by the Committee to possibly be
subject to the limitations on deductions imposed by Section 162(m) of the Code
("Named Executive Officers").  In the event of any inconsistencies between this
Section 17 and the other Plan provisions as they pertain to Named Executive
Officers, the provisions of this Section 17 shall control.

         17.2    Establishment of Performance Goals.   Awards for Named
Executive Officers, other than stock options and Stock Appreciation Rights,
shall be based on the attainment of certain performance goals.  No later than
the earlier of (i) ninety (90) days after the commencement of the applicable
fiscal year or such other award period as may be established by the Committee
("Award Period") and (ii) the completion of twenty-five percent (25%) of such
Award Period, the Committee shall establish, in writing, the performance goals
applicable to each such Award for Named Executive Officers.  At the time the
performance goals are established by the Committee, their outcome must be
substantially uncertain.  In addition, the performance goal must state, in
terms of an objective formula or standard, the method for computing the amount
of compensation payable to the Named Executive Officer if the goal is obtained.
Such formula or standard shall be sufficiently objective so that a third party
with knowledge of the relevant performance results could calculate the amount
to be paid to the subject Named Executive Officer.  The material terms of the
performance goals for Named Executive Officers and the compensation payable
thereunder shall be submitted to the shareholders of the Company for their
review and approval if and to the extent required under Section 162(m) of the
Code, and the Treasury Regulations thereunder.  Shareholder approval, if
necessary, shall be obtained for such performance goals prior to any Award
being paid to such Named Executive Officer.  If shareholder approval is
required and not received with respect to such performance goals, no amount
shall be paid to such Named Executive Officer for such applicable Award Period
under the Plan.

         17.3    Components of Awards.   Each Award of a Named Executive
Officer, other than stock options and Stock Appreciation Rights, shall be based
on performance goals which are sufficiently objective so that a third party
having knowledge of the relevant facts could determine whether the goal was
met.  Except as provided in Subsection 17.8 herein, performance measures which
may serve as determinants of Named Executive Officers' Awards shall be limited
to the following measures:  earnings per share; return on assets; return on
equity; return on capital; net profit after taxes; net profit before taxes;
operating profits; stock price; and sales or expenses.  Within ninety (90) days
following the end of each Award Period, the Committee shall certify in writing
that the performance goals, and any other material terms were satisfied.
Thereafter, Awards shall be made for each Named Executive Officer as determined
by the Committee.  The Awards may not vary from the preestablished amount based
on the level of achievement.

         17.4    No Mid-Year Change in Awards.   Except as provided in
Subsections 17.8 and 17.9 herein, each Named Executive Officer's Awards shall
be based exclusively on the performance measures established by the Committee
pursuant to Subsection 17.2.

         17.5    No Partial Award Period Participation.   A Named Executive
Officer who becomes eligible to participate in the Plan after performance goals
have been established in an Award Period pursuant to Subsection 17.2





                                      -13-
<PAGE>   14
may not participate in the Plan prior to the next succeeding Award Period,
except with respect to Awards which are stock options or Stock Appreciation
Rights.

         17.6    Performance Goals.   Except as provided in Subsection 17.8
herein, performance goals shall not be changed following their establishment,
and Named Executive Officers shall not receive any payout, except with respect
to Awards which are stock options or Stock Appreciation Rights, when the
minimum performance goals are not met or exceeded.

         17.7    Individual Performance and Discretionary Adjustments.   Except
as provided in Subsection 17.8 herein, subjective evaluations of individual
performance of Named Executive Officers shall not be reflected in their Awards,
other than Awards which are stock options or Stock Appreciation Rights.  The
payment of such Awards shall be entirely dependent upon the attainment of the
preestablished performance goals.

         17.8    Amendments.   No amendment of the Plan with respect to any
Named Executive Officer may be made which would (i) increase the maximum amount
that can be paid to any one Participant under the Plan, (ii) change the
specified performance goal for payment of  Awards, or (iii) modify the
requirements as to eligibility for participation in the Plan, unless the
Company's shareholders have first approved such amendment in a manner which
would permit the deduction under Section 162(m) of the Code of such payment in
the fiscal year it is paid.  The Committee shall amend this Section 17 and such
other provisions as it deems appropriate, to cause amounts payable to Named
Executive Officers to satisfy the requirements of Section 162(m) and the
Treasury Regulations promulgated thereunder.

         17.9    Stock Options and Stock Appreciation Rights.   Notwithstanding
any provision of the Plan (including the provisions of this Section 17) to the
contrary, the amount of compensation which a Named Executive Officer may
receive with respect to stock options and Stock Appreciation Rights which are
granted hereunder is based solely on an increase in the value of the applicable
Shares after the date of grant of such Award.  Thus, no stock option may be
granted hereunder to a Named Executive Officer with an exercise price less than
the Fair Market Value of Shares on the date of grant.  Furthermore, the maximum
number of Shares (or cash equivalent value) with respect to which stock options
or Stock Appreciation Rights may be granted hereunder to any Named Executive
Officer during any calendar year may not exceed 200,000 Shares, subject to
adjustment as provided in Section 13 hereunder.

         17.10   Maximum Amount of Compensation.   The maximum amount of
compensation payable as an Award (other than an Award which is a stock option
or Stock Appreciation Right) to any Named Executive Officer during any calendar
year may not exceed $1,000.000.
