Assets shall be held by the Sellers in trust for the Buyer and shall be
performed by the Buyer in the name of the Sellers and all benefits and
obligations derived thereunder shall be for the account of the Buyer; provided,
however, that where entitlement of the Buyer to such Transferred Assets

                  (c) Within three days of the Closing Date, the Sellers and the

assets owned or used by the Sellers or their Affiliates in connection with,
relating to or arising out of the Sellers' Business and operations conducted at
5605 Grand Avenue, Neville Island, Pennsylvania including, without limitation,
those assets of the Sellers listed or described in Section 1.2 of the Disclosure
Schedule provided that any Proprietary Information which is used by Sellers in
such operations and which is being transferred under this Agreement shall not be
excluded (collectively, the "Excluded Assets").

         1.3 Closing. Subject to the conditions set forth in this Agreement, the
closing shall take place at such time, date and place as the parties hereto
shall mutually agree upon in writing (the "Closing Date"). Failure to consummate
the transactions contemplated hereby on such date shall not result in a
termination of

                                       2

Date, (e) assume the liabilities and obligations of the Sellers' customers'
deposits in the aggregate amount set forth on Section 1.4(e) of the Disclosure
Schedule (the "Assumed Liabilities") and (f) assume the obligations of the
Sellers under the express written terms of the Entitlements to the extent and
only to the extent such obligations are not Pre-Closing Obligations (the
"Assumed Entitlements"), all of which Assumed Entitlements are listed in Section
1.1(a)(vi) of the Disclosure Schedule, which shall be updated and delivered by
the Sellers to the Buyer as of and on the Closing Date. The Cash Payment, the
Weatherford Shares, the Third Party Debt, the Assumed Trade Payables, the
Assumed Liabilities and the Assumed Entitlements are herein collectively

         1.5 Escrowed Shares.

                  (a) The Escrowed Shares shall be issued in the name of Sellers
and shall be issued and outstanding for all purposes, including the right to
vote, the certificates of which shares shall be held in escrow by National City
Bank of Pennsylvania (the "Escrow Agent") from the Closing until 5:00 p.m.,
Houston, Texas time, on the first anniversary of the Closing Date, as subject to
extension pursuant to Section 1.5(b) below (the "Escrow Term"). On the first
Business Day immediately following the expiration of the Escrow Term, the Escrow
Agent shall, as directed by Sellers or Sellers' Representative, release from
escrow and deliver to the Sellers the remaining balance of the account, if any,
including all Escrowed Shares, any cash and any investments held in escrow by
the Escrow Agent relating to dividends or distributions on, or proceeds from the
sale of, the Escrowed Shares and investments or interest earned on such cash and
investments remaining in escrow on such date, less such number of Escrowed
Shares and the amount of cash and investments as provided in Section 1.5(b).

                  (b) Notwithstanding anything to the contrary in this
Agreement, if on the expiration of the Escrow Term, any claims for
indemnification for Buyer Losses remain unresolved, the Escrow Agent may retain
in escrow a number of Escrowed Shares, any cash and any investments held in
escrow under the Escrow Agreement with an aggregate value equal to or less than
the amount of such unresolved claims for indemnification for Buyer Losses for so
long as such claims remain unresolved. For purposes of Sections 1.5(b) and
1.5(d), (i) the value of the Escrowed Shares shall be determined by multiplying
the number of Escrowed Shares by the Closing Date Value of the Weatherford
Shares, and any calculation of the number of the Escrowed Shares shall be
rounded up to the nearest whole share, and (ii) the value of all other
investments shall be the market value thereof as of the date such value is
determined.

                  (c) If the Sellers at any time or from time to time during the
Escrow Term desire to sell any of the Escrowed Shares or any of the other
investments held in the Escrow Account, they may do so; provided that (i) with
respect to any sale of Escrowed Shares, such sale is made pursuant to a
transaction registered under the Securities Act or the Sellers have provided to
Weatherford an opinion of counsel

                                       3
<PAGE>

satisfactory to Weatherford that an exemption from such registration exists;
(ii) each sale is in compliance with all applicable securities laws; (iii) the
Sellers have delivered in writing irrevocable instructions to the broker,
underwriter, purchaser or other Person who will pay the consideration in respect
of such sale, with a copy to Weatherford, directing such Person to remit the
proceeds from such sale to the Escrow Agent to be held in escrow. Subject to
compliance with all applicable securities laws, Sellers may elect to invest the
proceeds from any sale of Escrowed Shares only in interest-bearing deposit
accounts or short-term U.S. Government Obligations such as Treasury Bills,
provided that all securities and proceeds resulting from such transactions shall
be held in escrow and shall be subject to this Section 1.5. It is the Sellers'
sole responsibility to seek the advice of their own representatives, advisors
and legal counsel to determine for themselves the advisability and legality of
entering into any such investments. The Sellers agree that neither the Buyer nor
Weatherford shall have any liability to the Sellers in connection with any such
investments.

                  (d) Whenever any number of Escrowed Shares or amount of cash
is to be withdrawn from the escrow by the Buyer pursuant to this Agreement, the
Escrow Agent shall (A) first withdraw cash, to the extent thereof, (B) the
remaining amount to be withdrawn, if any, shall next be withdrawn from
investments other than Escrowed Shares and cash, and such investments shall be
promptly liquidated by the Escrow Agent (at the Sellers' direction) to the
extent necessary to satisfy the rights of withdrawal of Buyer pursuant to this
Agreement, it being understood and agreed that it shall be deemed necessary to
liquidate any derivative securities relating to securities of Weatherford, and
(c) the remaining amount to be withdrawn, if any, shall be made from Sellers'
Escrowed Shares (based on the Closing Date Value).

                  (e) Any dividends or distributions paid or payable with
respect to the Escrowed Shares or any other securities or investments held in
escrow, cash proceeds resulting from any sale of the Escrowed Shares or any
other securities or investments pursuant to paragraph (c) of this Section 1.5
and any interest earned on any of those amounts shall be transferred to Escrow
Agent and held in escrow and shall be subject to the terms of this Section 1.5.
All cash deposited with the Escrow Agent shall earn interest at applicable rates
paid by the Escrow Agent from time to time to its best customers for deposits of
similar amount and tenor.

                  (f) Weatherford shall have the right to withdraw Escrowed
Shares by way of repurchase for an aggregate purchase price of $1.00,
investments (which must be reduced to cash) or cash or any combination of the
foregoing from the escrow to satisfy any payments required to be made to the
Buyer or Weatherford under Article 8; provided, that prior to any such
withdrawal, the Buyer or Weatherford shall have received from the Seller
Representative a certificate stating that the Buyer or Weatherford, as the case
may be, is entitled to receive a payment pursuant to Article 8 and stating the
dollar amount of such payment. If, however, the parties hereto agree that the
Buyer or Weatherford is entitled to receive a payment, but disagree as to the
amount of such payment, the Sellers agree that the Seller Representative shall
deliver such certificate authorizing the withdrawal of the amount not in
dispute. Notwithstanding the foregoing, no such certificate shall be required if
the Buyer or Weatherford delivers to the Seller Representative a copy of a
decision of an arbitration body selected and convened in accordance with Section
12.4 stating that the Buyer or Weatherford is entitled to indemnity pursuant to
this Agreement and stating the dollar amount of such indemnification.

         1.6 Purchase Price Adjustment.

                  (a) The Buyer shall within 90 calendar days after the Closing
Date prepare or cause to be prepared a statement reflecting the Closing Date
Asset Value and the calculation thereof (the "Closing Statement") and shall
deliver such Closing Statement to the Representative. The Closing Statement
shall be prepared on a basis consistent with that used in calculating the Target
Asset Value. The Buyer shall provide the Representative with access to copies of
all work papers and other relevant documents to verify the information contained
in the Closing Statement. The Representative shall have a period of 30 calendar
days

                                       4
<PAGE>

after delivery to him of the Closing Statement to review it and make any
objections in writing to the Buyer. If written objections to the Closing
Statement are delivered to the Buyer within such 30-day period, then the Buyer
and the Representative shall attempt to resolve the matter or matters in
dispute. If no written objections are made within the time period provided
above, the Closing Statement shall become final and binding on the parties
hereto and the Cash Payment shall be adjusted as described in clause (c) below.

                  (b) If disputes with respect to the Closing Statement cannot
be resolved by the Buyer and the Representative within 15 calendar days after
the delivery of the objections to the Closing Statement, then either party with
notice to the other party may submit the specific matters in dispute to
PriceWaterhouseCoopers LLP or such other recognized independent accounting firm
as may be approved by the Buyer and the Representative, which firm shall render
its opinion as to such matters. Based on such opinion, such accounting firm will
then send to the Buyer and the Representative its determination in writing on
the specific matters in dispute, including any resulting revisions to the
Closing Statement, which determination shall be final and binding on the parties
hereto. The Closing Statement, including revisions, if any, made by such
accounting firm, shall then become final and binding on the parties hereto and
the Purchase Price shall be adjusted as described in clause (c) below. The fees
and other costs charged by the independent accounting firm shall be borne by the
Buyer and the Sellers equally.

                  (c) At the time the Closing Statement becomes final and
binding on the parties hereto, the Purchase Price will be:

                           (i) reduced by the amount, if any, by which the
         Target Asset Value exceeds the Closing Date Asset Value; and

                           (ii) increased by the amount, if any, by which the
         Closing Date Asset Value exceeds the Target Asset Value.

If the Purchase Price is reduced pursuant to clause (i) above, the Sellers
shall, within five days of the date that the Closing Statement becomes final and
binding on the parties hereto, pay to the Buyer cash in an amount equal to such
reduction. If the Purchase Price is increased pursuant to clause (ii) above, the
Buyer shall, within five days of the date that the Closing Statement becomes
final and binding on the parties hereto, pay to the Sellers cash in an aggregate
amount equal to such increase.

                  (d) All payments made pursuant to this Section 1.6 shall be
paid in immediately available funds by wire transfer to a bank account or
accounts to be designated by the party to receive the payments. All payments
made pursuant to this Section 1.6 shall be deemed to be adjustments to the
Purchase Price effective on the date that the Closing Statement becomes final
and binding on the parties hereto.

                  (e) For purposes of preparing the Closing Statement, (i) there
shall be no increases in the net book value of any of the Transferred Assets by
virtue of any adjustments made after December 31, 2001 other than as set forth
in this clause (e), (ii) except as provided for in (v), increases or decreases
in the Transferred Assets shall reflect only increases or decreases resulting
from transactions in the ordinary course of the Business after December 31,
2001, (iii) there shall be no increases in the assets of the Business due to the
recognition of any non-cash increases in the Transferred Assets (including
translation adjustments), other than in the ordinary course of business, (iv)
there shall be no adjustments for extraordinary charges or expenses after
December 31, 2001, (v) the net book value of Inventories shall be reduced for
Inventories which are damaged, obsolete or otherwise not salable, (vi) the net

older than 120 days; provided, however, that any such Account Receivable, or any
portion thereof, actually collected prior to 90 days after the Closing Date
shall be included in the Closing Date Asset Value, (vii) there shall be no
adjustments for increases in intangibles, (viii) the net book value of Equipment
shall be

                                       5
<PAGE>

reduced by the net book value of any Equipment which is not in good working
order or which is not in the Sellers' possession as of the Closing Date and (ix)
there shall be no increases in net book value of Equipment unless such Equipment
was acquired after December 31, 2001 with the consent of the Buyer.

Retained Liabilities.

acknowledge and agree that any and all sales, use, value added, stamp, transfer
or other similar Taxes imposed as a result of the consummation of the
transactions contemplated by this Agreement shall be borne equally by the Buyer,

                  (a) The Sellers and each of the Shareholders warrant that the
Transferred Assets are not, and on the Closing Date will not be, subject to or
liable for any special assessments or similar types of impositions. Any general
property Tax assessed against or pertaining to the Transferred Assets for the
taxable period that includes the Closing Date shall be prorated between the
Buyer and the Sellers as of the Closing

                                       6
<PAGE>

Date. In the event the amount of any such general property Tax cannot be
ascertained as of the Closing Date, proration shall be made on the basis of the
preceding year, the Buyer shall receive a credit against the Cash Payment for
the Sellers' pro rata portion of such general property Taxes, and to the extent
that such proration may be inaccurate, the Sellers and the Buyer agree to make
such payment to the other after the tax statements have been received as is

and other items of expense attributable to the conduct of the Business shall be
prorated as of the Closing Date to the extent the charges and expenses cannot be
identified as to the party that received the benefits to which such charges and
expenses relate. The Buyer shall receive a credit against the Cash Payment for
the Seller's pro rata portion of such charges and expenses. To the extent such
amounts are estimated on the Closing Date and such prorations are inaccurate,
the Seller and the Buyer agree to make such payment to the other after such
amounts are correctly computed as is necessary to allocate such charges properly
between the Sellers and the Buyer as of the Closing Date.

                  (c) The Sellers shall receive a credit, to be paid at Closing,
for the amount of prepaid expenses and deposits relating to the Entitlements, to
the extent and only to the extent that such prepaid expenses and deposits are
Transferred Assets and are not reflected on the Financial Statements. In
addition, the Sellers shall receive a credit on the final Closing Statement in
the amount of any prepaids collected by the Buyer within 90 calendar days after
the Closing Date in excess of their Closing Date Asset Value.

         1.11 Adjustments for Changes in Capitalization. For purposes of this
Article 1, references to the Common Stock and Weatherford Shares shall include
any stock, securities, cash or other property into which the Common Stock has
been converted or that may be received by a shareholder who held a share of
Common Stock on the Closing Date in respect of such share and all references to
the market value of the Common Stock as of any date shall mean the sum of the
market value of Common Stock and such other stock, securities, cash or other
property that may be received by a holder of Common Stock in respect of a share
of Common Stock as of the date of the Closing. The determination of the value of
any security shall be based on the closing sale price of that security on the
principal stock exchange on which it is listed if that security is traded on a
national securities exchange. If the principal market in which a security is
traded is an automated trading system, such as NASDAQ, the market value on any
day shall be the average of the high and low bid price for that security on that
day. If any other security or property is received, its value shall be
determined by agreement by a nationally recognized investment banking firm
selected in good faith by Weatherford. In the event of a reclassification of the
Common Stock into a greater or lesser number of shares of Common Stock, all
references to numbers of shares of Common Stock and all market prices for the
Common Stock shall be appropriately adjusted to reflect such reclassification.

Section 4.1, Weatherford shall be permitted, on written notice to the Sellers,

time when Weatherford reasonably believes that the sale or distribution thereof
would adversely affect a pending or proposed public offering of securities of
Weatherford, an acquisition, amalgamation, merger, recapitalization,
consolidation, reorganization or similar transaction relating to Weatherford or
negotiations, discussions or pending proposals with respect thereto or require
premature disclosure of information not otherwise required to be disclosed to

or supplement thereto, by Weatherford may not be deferred pursuant to Section

as the Seller Group may reasonably request, in order to facilitate the public
sale or other disposition of the Weatherford Shares owned by the Seller Group;

                  (d) as expeditiously as practicable, use its best efforts to
register or qualify the Weatherford Shares under such other securities laws of
such United States jurisdictions as the Seller Group shall reasonably request

and things which may be necessary or desirable to enable the Seller Group to
consummate the public sale or other disposition in such jurisdictions of the
Weatherford Shares; provided, however, that Weatherford shall not be required to
qualify to transact business as a foreign corporation in any jurisdiction in
which it would otherwise not be required to be so qualified or to take any
action which would subject it to general service of process in any jurisdiction
in which it is not then so subject;

                  (e) bear all Registration Expenses (as defined below) in
connection with the registration hereunder; provided, however, that all Selling

shorter period of time until the transfer or sale of all the Weatherford Shares

         4.3 Indemnification.

                  (a) In the event of a registration of the Weatherford Shares
under the Securities Act pursuant to this Agreement, Weatherford will indemnify
and hold harmless the Seller Group and any other Person, if any, who controls
the Seller Group within the meaning of Section 15 of the Securities Act, against
any losses, claims, damages or liabilities, joint or several, to which the
Seller Group or such controlling Person may become subject under the Securities
Act or otherwise, insofar as such losses, claims, damages or liabilities or
actions in respect thereof arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained, on the effective
date thereof, in the Registration Statement, any preliminary prospectus
distributed with the consent of Weatherford or final prospectus contained
therein, or any amendment thereof or supplement thereto, including all documents
incorporated by reference therein, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will, unless Weatherford assumes the defense as provided in Section 4.3(c),
promptly following request and receipt of reasonable supporting documents, such
as invoices, reimburse the Seller Group and each such controlling Person for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that Weatherford will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in such Registration Statement, such preliminary prospectus, such
final prospectus or such amendment or supplement, including all documents
incorporated by reference therein, in reliance upon and in conformity with
written information furnished to Weatherford by or on behalf of the Seller Group
or a controlling Person thereof specifically for use in the preparation thereof.

                  (b) In the event of any registration of the Weatherford Shares
under the Securities Act pursuant to this Agreement, the Sellers and the
Shareholders will jointly and severally indemnify and hold harmless Weatherford
and the Buyer and each Person, if any, who controls Weatherford or the Buyer
within the meaning of Section 15 of the Securities Act, each officer of
Weatherford who signs the Registration Statement, each director of Weatherford
and each Person who controls any underwriter (if any) within the

                                       19
<PAGE>

meaning of Section 15 of the Securities Act, against any and all such losses,
claims, damages, liabilities or actions which Weatherford or such officer,
director, underwriter (if any) or controlling Person may become subject under
the Securities Act or otherwise, and will reimburse Weatherford, each such
officer, director, underwriter (if any) and controlling Person for any legal or
any other expenses reasonably incurred by such party in connection with
investigating or defending any such loss, claim, damage, liability or action, if
(i) such loss, claim, damage, liability or action in respect thereof arises out
of or is based upon any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement or any such prospectus, or
any amendment thereof or supplement thereto, or arises out of or is based upon
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading and
such statement or omission of a material fact was made in reliance upon and in
conformity with information furnished to Weatherford by or on behalf of the
Seller Group specifically for use in connection with the preparation of the
Registration Statement or prospectus or (ii) such loss, claim, damage, liability
or action in respect thereof arises out of or is based upon the Seller Group's
failure to deliver any required prospectus or otherwise comply with applicable
laws regarding the same. In addition, as a condition to the inclusion of any
Weatherford Shares held by any other member of the Selling Group in any
registration of the Weatherford Shares under the Securities Act pursuant to this
Agreement, such Person shall agree to be bound by the indemnification
obligations set forth in this Article 4, but only with respect to information
provided by or on behalf of such Person.

                  (c) Promptly after receipt by any indemnified Person of notice
of any claim or commencement of any action in respect of which indemnity is to
be sought against an indemnifying Person pursuant to this Agreement, such
indemnified Person shall notify the indemnifying Person in writing of such claim
or of the commencement of such action, and, subject to provisions hereinafter
stated, in case any such action shall be brought against an indemnified Person
and such indemnifying Person shall have been notified of the same, such
indemnifying Person shall be entitled to participate therein, and, to the extent
it shall wish, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified Person, and after notice from the indemnifying
Person to such indemnified Person of its election to assume the defense thereof,
such indemnifying Person shall not be liable to such indemnified Person in
connection with the defense thereof; provided, however, if there exists or will
exist a conflict of interest which would make it inappropriate in the reasonable
judgment of the indemnified Person for the same counsel to represent both the
indemnified Person and such indemnifying Person then such indemnifying Person
shall be entitled to retain its own counsel at the expense of such indemnifying
Person; provided further, however, the indemnifying Person shall not be required
to pay for more than one separate counsel for all of the indemnified Persons in
addition to any local counsel. Payment of any amounts due pursuant to this
Section 4.3 shall be made within ten Business Days after notice is sent by the
indemnified Person.

         4.4 Termination. If the holding period under Rule 144 or Rule 145 as
promulgated under the Securities Act or any successor or similar rule or statute
is reduced to permit the sale of the Weatherford Shares, the rights of the
Seller Group as to the registration provided for in this Agreement as to the
Weatherford Shares shall terminate immediately.

including soil and groundwater sampling, as it deems appropriate. No
investigations by the Buyer or its employees, representatives or agents shall
reduce or otherwise affect the obligation or liability of any of the Sellers or
any of the Shareholders with respect to any representations, warranties,
covenants or agreements made herein or in any exhibit, schedule or other
certificate, instrument, agreement or document, including the Disclosure
Schedule, executed and delivered in connection with this Agreement. Each of the

         full force and effect;

         by any of the Entitlements and all Taxes other than Taxes that are

Shareholders agree that from the date hereof until the Closing Date or the
termination of this Agreement pursuant to Section 10.1, such Person will not,
directly or indirectly, solicit, encourage or negotiate with any Person not a
party hereto or not affiliated with a party hereto with respect to a merger,
amalgamation, consolidation, asset or stock purchase or any similar transaction
with the Seller.

         5.4 Information. During the period from the date of this Agreement to
the Closing Date, the Buyer and the Sellers and each of the Shareholders will
promptly inform the others in writing of any claim, action or any proceeding
commenced against such party with respect to the transactions contemplated by
this Agreement or any assets or property of the Sellers or the Transferred
Assets.

         5.5 Delivery of Business Documents. At Closing, the Sellers and the
Shareholders shall deliver to the Buyer all Documents and Other Papers relating
to the Transferred Assets and the current and proposed operations of the
Business, including, without limitation, all files relating to the Accounts

Entitlements, copies of all insurance policies and all files relating thereto,
computer disks reflecting any books or records, documents or other papers, or

                                       22
<PAGE>

information or data relating to the operation of the Business or the Transferred
Assets stored on any electronic media, including computers. The Seller, however,
shall be entitled to retain the corporate minute books, stock books and tax
returns of the Seller and to have access to the books and records relating to
the Business to the extent such books and records are necessary for the
preparation of tax returns or other proper business purposes.

         5.6 Further Assurances. Each of the Sellers and each of the
Shareholders shall execute, acknowledge and deliver or cause to be executed,
acknowledged and delivered to the Buyer such bills of sale, assignments
(including but not limited to assignments of leases) and other instruments of
transfer, assignment and conveyance, in form and substance reasonably
satisfactory to counsel for the Buyer, as shall be necessary to vest in the
Buyer all the right, title and interest in and to the Transferred Assets free
and clear of all Liens (including the release of all Liens of record) and shall
use their best efforts to cause to be taken such other action as the Buyer
reasonably may require to more effectively implement and carry into effect the
transactions contemplated by this Agreement.

         5.7 Nondisclosure of Proprietary Information.

                  (a) Each of the Sellers and each of the Shareholders agree
that, from and after the Closing, such Seller or Shareholder and such Person's
Affiliates shall (i) hold in confidence and will not directly or indirectly at
any time reveal, report, publish, disclose or transfer to any Person other than
the Buyer any of the Proprietary Information that is not generally known to the
public or utilize any of the Proprietary Information for any purpose and (ii)
not for a period of three years solicit or hire any employees of the various
Sellers who are subsequently employed by the Buyer or offered employment by the
Buyer.

                  (b) Each of the Sellers and each of the Shareholders
acknowledge that all Documents and Other Papers and objects containing or
reflecting any Proprietary Information, whether developed by such Seller or
Shareholder or by someone else for such Seller or Shareholder or any of such
Person's Affiliates, will after the Closing become the exclusive property of the
Buyer and be delivered to the Buyer.

                  (c) Because of the unique nature of the Proprietary
Information, each of the Sellers and each of the Shareholders understand and
agree that the breach or anticipated breach of the obligations under this
Section 5.7 will result in immediate and irreparable harm and injury to the
Buyer and its Affiliates, for which it will not have an adequate remedy at law,
and that the Buyer and its Affiliates and their successors and assigns shall be
entitled to relief in equity to enjoin such breach or anticipated breach and to
seek any and all other legal and equitable remedies to which they may be
entitled.

         5.8 Covenant Not to Compete With the Business. As an inducement for the
Buyer to acquire the Business, each of the Sellers and each of the Shareholders
agree that, effective as of the Closing Date and for a period of five years
thereafter, none of the Sellers, the Shareholders nor any of their respective
Affiliates shall, without the consent of the Buyer, directly or indirectly,
develop, formulate, blend, manufacture, distribute, market, produce, sell or
provide specialty chemicals for use in the oilfield and gas services industry in
any geographical area of the world, or, except for the benefit of Buyer and its
Affiliates, assist any Person to do the same; provided, however, Buyer consents
to the loan in the principal amount of $75,000 made by a CWII Shareholder to
Bio-Science Corporation and the continuation of Sellers' operations at 5605
Grand Avenue, Neville Island, Pennsylvania, through March 31, 2003 or such
earlier time by which Sellers may be able to wind up such operations. Each of
the Sellers and each of the Shareholders acknowledge that a remedy at law for
any breach or attempted breach of this Section 5.8 will be inadequate and
further agree that any breach of this Section 5.8 will result in irreparable
harm to the Business and the Buyer shall, in addition to any other remedy that
may be available to it, be entitled to specific performance and injunctive and
other equitable relief in case of any such breach or attempted breach. Each of
the Sellers and each of the Shareholders acknowledge that this covenant not to
compete is being provided as an inducement to the Buyer to acquire the Business
and the

                                       23
<PAGE>

Transferred Assets and that this Section 5.8 contains reasonable limitations as
to time, geographical area and scope of activity to be restrained that do not
impose a greater restraint than is necessary to protect the goodwill or other
business interest of the Buyer. Whenever possible, each provision of this
Section 5.8 shall be interpreted in such a manner as to be effective and valid
under applicable law but if any provision of this Section 5.8 shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remaining provisions of this Section 5.8. If any provision of
this Section 5.8 shall, for any reason, be judged by any court of competent
jurisdiction to be invalid or unenforceable, such judgment shall not affect,
impair or invalidate the remainder of this Section 5.8 but shall be confined in
its operation to the provision of this Section 5.8 directly involved in the
controversy in which such judgment shall have been rendered. In the event that
the provisions of this Section 5.8 should ever be deemed to exceed the time or
geographic limitations permitted by applicable laws, then such provision shall
be reformed to the maximum time or geographic limitations permitted by
applicable law.

         5.9 Use of Names. All uses of the names "Clearwater, Inc.",
"Clearwater", "Clearwater Specialty Chemical Co.", "Transit Energy Systems,
Inc.", "Transit", "PriTech International, Inc." and "PriTech" or any derivations
thereof (collectively, the "Names") are being transferred to the Buyer hereunder
as part of the Transferred Assets; provided, however, that Buyer consents and
agrees to Sellers' continued use of the names "Clearwater" and Clearwater, Inc."
for the limited purpose of winding up its manufacturing operations at Neville
Island, Pennsylvania, for the five-month period immediately after Closing Date.
Each of the Sellers and each of the Shareholders agree not to take any action
which could reasonably be expected to adversely affect the Buyer's right to the
Names or cause confusion with respect to the Buyer's use of the Names. All
goodwill with respect to the use of the Names will inure to the benefit of the
Buyer, and none of the Sellers or any of the Shareholders will have any rights
to sue or recover against any person with respect to the use of the Names.
Within five months after Closing, each Seller agrees to take all necessary
action to change the Seller's name to one bearing no resemblance to any of the
Names or any derivation thereof and will forever cease the use of such names.

         5.10 Employee Matters

                  (a) The Buyer will, in its sole discretion, offer employment
to any or all of the employees of the Sellers listed on Schedule 5.10 hereof on
terms substantially similar to those offered by the Buyer to similarly situated
employees. Any such employees that the Buyer in fact employs immediately after
the Closing Date shall hereinafter be referred to as the "Transferred
Employees". All of the Sellers' employees who are not employed by the Buyer or
one of its Affiliates immediately after the Closing Date shall hereinafter be
referred to as the "Seller Retained Employees". The Sellers and the Shareholders
shall be responsible and liable for any and all severance obligations with
respect to the Seller Retained Employees, provided, however, that the Buyer
shall make COBRA coverage available to the Sellers' COBRA beneficiaries, at
Buyer's COBRA rates, from and after the date on which the Sellers terminate and
cease to provide a group health plan.

                  (b) The parties hereto do not intend to create any third-party
beneficiary rights respecting any employee of the Sellers as a result of the
provisions hereof and specifically hereby negate any such intention.

                  (c) In determining eligibility for and entitlement to vacation
and other normal benefits (excluding stock-based plans and incentive programs)
based on length of service by Transferred Employees under the Buyer's normal
policies, service with the Sellers shall be considered by the Buyer as service
with the Buyer.

         5.11 Continuation of Business by the Buyer. Nothing in this Agreement,
in any exhibit or schedule thereto or in any agreement, instrument or other
document executed or delivered in connection with this

                                       24
<PAGE>

Agreement shall require the Buyer to continue the Business or to manage and
operate the Transferred Assets with any duty or standard or care to any of the
Sellers or any of the Shareholders. Each of the Sellers and each of the
Shareholders acknowledge and agree that the Buyer in its sole discretion may
continue, manage, modify or discontinue the operations, liquidate or otherwise
change or cease the operations of the Business and the Transferred Assets.

         5.12 Title Policies. As soon as possible after Closing, Sellers shall
cause Stewart Title Guaranty Company (the "Title Company") to furnish to the
Buyer, at the Sellers' sole cost and expense, an Owner Policy of Title Insurance
covering the Elmendorf Property (the "Elmendorf Title Policy") which shall be in
the customary form prescribed by the Texas State Board of Insurance. The
Elmendorf Title Policy may contain as exceptions those matters as shown on a
commitment of title insurance issued by the Title Company (the "Permitted
Exceptions"); provided, however, that (i) the standard exception for
restrictions shall be deleted except for any restrictions that are Permitted
Exceptions, (ii) the exception for rights of parties in possession shall be
deleted, (iii) the standard exception for taxes shall be limited to the year in
which the Closing occurs (if such taxes are not yet due and payable), (iv) all
arbitration provisions shall be deleted, (v) all matters set forth on Schedule C
of the Title Commitment shall be deleted, and (vi) the "survey exception" shall
be modified to read "shortages in area." For purposes of this Section 5.12,
"Elmendorf Property" shall mean the Real Property owned by CWI set forth in
Section 1.1(a)(v) of the Disclosure Schedule located in Lot 6, Block 1, Braunig
Lake Estates, Elmendorf, Texas.

                                 INDEMNIFICATION

         8.1 Indemnification by the Seller and the Shareholders. Except as
otherwise limited by this Article 8 and Article 9 hereof, each of the Sellers
and each of the Shareholders, jointly and severally, agree to indemnify, defend
and hold the Buyer and Weatherford, each of their respective Affiliates and each
of their respective officers, directors, employees, agents, stockholders and
controlling Persons and their respective successors and assigns harmless from
and against and in respect of Damages actually suffered, incurred or realized by
such party (collectively, "Buyer Losses"), arising out of or resulting from or
relating to:

                  (a) any misrepresentation, breach of warranty or breach of any
covenant or agreement made or undertaken by any of the Sellers or any of the
Shareholders in this Agreement or any misrepresentation in or omission from any
other agreement, certificate, exhibit or writing delivered to the Buyer or
Weatherford pursuant to this Agreement, including the Disclosure Schedule;

                  (b) any Environmental Liability arising from or attributable
to (i) any condition, event, circumstance, activity, practice, incident, action
or omission existing or occurring prior to the Closing Date and related in any
way to the Transferred Assets or the Business, or (ii) the use, storage,
disposal or treatment, or the transportation for storage, disposal or treatment,
of Hazardous Materials prior to the Closing Date and related in any way to the
Transferred Assets or the Business; or

                  (c) any Retained Liability.

For purposes of determining the Buyer's and Weatherford's right to
indemnification for a misrepresentation or breach of warranty made by any of the
Sellers or any of the Shareholders in this Agreement, all such representations
and warranties that have been made subject to a materiality qualification shall
be deemed to have been made without that qualification.

                                       28
<PAGE>

         8.2 Indemnification by the Buyer and Weatherford. Except as otherwise
limited by this Article 8 and Article 9 hereof, the Buyer and Weatherford,
jointly and severally, agree to indemnify, defend and hold the Sellers and the
Shareholders and each of their respective officers, directors, employees,
agents, shareholders and controlling Persons and successors and assigns harmless
from and against and in respect of Damages actually suffered, incurred or
realized by such party (collectively, "Seller Losses"), arising out of or
resulting from or relating to (a) any misrepresentation, breach of warranty or
breach of any covenant or agreement made or undertaken by the Buyer or
Weatherford in this Agreement or any misrepresentation in or omission from any
other agreement, certificate, exhibit or writing delivered to the Sellers or the
Shareholders pursuant to this Agreement, (b) any Assumed Liability, (c) any
Assumed Trade Payable or (d) any Assumed Entitlement.

         8.3 Procedure. All claims for indemnification under this Article 8
shall be asserted and resolved as follows:

                  (a) An Indemnitee shall promptly give the Indemnitor notice of
any matter which an Indemnitee has determined has given or could give rise to a
right of indemnification under this Agreement, stating the amount of the Losses,
if known, and method of computation thereof, all with reasonable particularity,
and stating with particularity the nature of such matter. Failure to provide
such notice shall not affect the right of the Indemnitee to indemnification
except to the extent such failure shall have resulted in liability to the
Indemnitor that could have been actually avoided had such notice been provided
within such required time period.

                  (b) The obligations and liabilities of an Indemnitor under
this Article 8 with respect to Losses arising from claims of any third party
that are subject to the indemnification provided for in this Article 8 ("Third
Party Claims") shall be governed by and contingent upon the following additional
terms and conditions: if an Indemnitee shall receive notice of any Third Party
Claim, the Indemnitee shall give the Indemnitor prompt notice of such Third
Party Claim and the Indemnitor may, at its option, assume and control the
defense of such Third Party Claim at the Indemnitor's expense and through
counsel of the Indemnitor's choice reasonably acceptable to Indemnitee. In the
event the Indemnitor assumes the defense against any such Third Party Claim as
provided above, the Indemnitee shall have the right to participate at its own
expense in the defense of such asserted liability, shall cooperate with the
Indemnitor in such defense and will attempt to make available on a reasonable
basis to the Indemnitor all witnesses, pertinent records, materials and
information in its possession or under its control relating thereto as is
reasonably required by the Indemnitor. In the event the Indemnitor does not
elect to conduct the defense against any such Third Party Claim, the Indemnitor
shall pay all reasonable costs and expenses of such defense as incurred and
shall cooperate with the Indemnitee (and be entitled to participate) in such
defense and attempt to make available to it on a reasonable basis all such
witnesses, records, materials and information in its possession or under its
control relating thereto as is reasonably required by the Indemnitee. Except for
the settlement of a Third Party Claim that involves the payment of money only
and for which the Indemnitee is totally indemnified by the Indemnitor, no Third
Party Claim may be settled without the written consent of the Indemnitee.

         8.4 Payment. Payment of any amounts due pursuant to this Article 8
shall be made in immediately available funds by wire transfer to a bank account
or accounts to be designated by the Indemnitee within ten Business Days after
notice is sent by the Indemnitee.

         8.5 Failure to Pay Indemnification. If and to the extent the Indemnitee
shall make written demand upon the Indemnitor for indemnification pursuant to
this Article 8 and the Indemnitor shall refuse or fail to pay in full within ten
Business Days of such written demand the amounts demanded pursuant hereto and in
accordance herewith, then the Indemnitee may utilize any legal or equitable
remedy to collect from the Indemnitor the amount of its Losses. Nothing
contained herein is intended to limit or constrain the Indemnitee's

                                       29
<PAGE>

rights against the Indemnitor for indemnity, the remedies herein being
cumulative and in addition to all other rights and remedies of the Indemnitee.

         8.6 Adjustment of Liability. The amount which an Indemnitee shall be
entitled to receive from an Indemnitor with respect to any indemnifiable Losses
under this Article 8 shall be net of any insurance recovery by the Indemnitee on
account of such Losses from an unaffiliated party.

         8.7 Express Negligence. THE INDEMNITIES SET FORTH IN THIS ARTICLE 8 ARE
INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS
TERMS AND SCOPE THEREOF NOTWITHSTANDING TEXAS' EXPRESS NEGLIGENCE RULE OR ANY
SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF
THE SIMPLE OR GROSS NEGLIGENCE (WHETHER SOLE, CONCURRENT, ACTIVE OR PASSIVE) OR
OTHER FAULT OR STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES.

         8.8 Indemnification Limitations.

                  (a) The Sellers and the Shareholders shall not be liable under
Section 8.1(a) in respect of a misrepresentation or breach of warranty until the
aggregate amount of any Buyer Losses for which the Buyer is entitled to
indemnification pursuant to such clause exceeds $100,000; provided, however, the
Sellers' and the Shareholders' liability under Section 8.1(a) shall not be so
limited if such Buyer Losses arise from a breach of any of the representations
set forth in Sections 2.1, 2.2, 2.4, 2.9, 2.13, or 2.15.

                  (b) The aggregate liability of the Sellers and Shareholders
under Section 8.1(a) for Buyer Losses arising from a breach of any
representation or warranty other than those set forth in Sections 2.1, 2.2, 2.4,
2.9, 2.13 and 2.15 shall not exceed $30,569,937.

                  (c) The liability of the Sellers and the Shareholders for
Buyer Losses arising from any Retained Liability, Environmental Liability under
Section 8.1(b), breach of any covenants or agreements, or breach of any of the
representations set forth in Sections 2.1, 2.2, 2.4, 2.9, 2.13, and 2.15 shall
not be subject to either the $100,000 deductible set forth in Section 8.8(a) or
the maximum limit contained in Section 8.8(b).

                                    ARTICLE 9

                 NATURE OF STATEMENTS AND SURVIVAL OF COVENANTS,
                   REPRESENTATIONS, WARRANTIES AND AGREEMENTS

         All statements of fact contained in any written statement (including
financial statements), certificate, instrument or document delivered by or on
behalf of any of the Sellers or any of the Shareholders pursuant to this
Agreement or that form a part of this Agreement, the Disclosure Schedule or the
closing documents shall be deemed representations and warranties of the Sellers
and the Shareholders. The several representations and warranties of the parties
to this Agreement shall survive the Closing Date for a period of two years from
the Closing Date (except that the representations and warranties set forth in
Sections 2.1, 2.2, 2.4, 2.9, 2.13, 2.15, 3.1, 3.3 and 3.4 shall survive the
Closing Date without limitation) (the period during which the representations
and warranties shall survive being referred to herein with respect to such
representations and warranties as the "Survival Period"), and shall be effective
with respect to any inaccuracy therein or breach thereof (and a claim for
indemnification under Article 8 hereof may be made thereon) if a written notice
asserting the claim shall have been given within the Survival Period with
respect to such matter. Any claim for indemnification made during the Survival
Period shall be valid and the representations and warranties relating thereto
shall remain in effect for purposes of such indemnification notwithstanding such
claim may not

                                       30
<PAGE>

be resolved within the Survival Period. The agreements and covenants set forth
herein and the Sellers' and the Shareholders' obligations to indemnify the Buyer
with respect to Environmental Liabilities under Section 8.1(b) and Retained
Liabilities under Section 8.1(c) shall survive without limitation. All
representations, warranties, covenants and agreements made by the parties shall
not be affected by any investigation heretofore or hereafter made by and on
behalf of either of them and shall not be deemed merged into any instruments or
agreements delivered in connection with this Agreement or otherwise in
connection with the transactions contemplated hereby. THE DISCLOSURE OF ANY ITEM
IN ANY EXHIBIT, SCHEDULE OR OTHER CERTIFICATE, INSTRUMENT, AGREEMENT OR
DOCUMENT, INCLUDING THE DISCLOSURE SCHEDULE, SHALL NOT RELIEVE THE SELLERS OR
THE SHAREHOLDERS OF ANY OBLIGATION HEREUNDER TO INDEMNIFY THE BUYER FOR ANY
BUYER LOSSES RESULTING FROM OR ARISING OUT OF ANY SUCH ITEM AND SHALL NOT AFFECT
THE CLASSIFICATION OF ANY SUCH ITEM AS A RETAINED LIABILITY.

                                   ARTICLE 10

                                   TERMINATION

         10.1 Termination. The obligation to close the transactions contemplated

and representations of the Sellers and the Shareholders herein contained, and
such default or breach has not been cured or has not been waived;

                  (c) the Sellers and the Shareholders, if a material default

timely performance by the Buyer or Weatherford of any agreements and covenants
of the Buyer and Weatherford herein contained, or if there shall have been a
breach by the Buyer or Weatherford of any of the warranties and representations
of the Buyer and Weatherford herein contained, and such default or breach has
not been cured or has not been waived; or

                  (d) the Buyer and Weatherford or the Sellers and the
Shareholders (provided the terminating parties have not materially breached any

         10.2 Liability Upon Termination. If the obligation to close the

provisions of this Agreement on the part of the Seller, the Shareholders, the
Buyer or Weatherford except and to the extent such termination results from the
willful breach by a party of any of its representations, warranties or
agreements hereunder and except that the termination of this Agreement shall not
relieve any party of its obligations under Section 5.1(b), Article 8 (but only
to the extent it applies to breaches of the warranties made in Section 2.13 and
Section 3.3), Section 12.2 and Section 12.7.

         BMC Software, Inc. 2002 Nonemployee Director Stock Option Plan

                               BMC SOFTWARE, INC.

                   2002 NONEMPLOYEE DIRECTOR STOCK OPTION PLAN

                                   I. PURPOSE

         The purpose of the BMC SOFTWARE, INC. 2002 NONEMPLOYEE DIRECTOR STOCK
OPTION PLAN (the "Plan") is to provide a means through which BMC SOFTWARE, INC.,
a Delaware corporation (the "Company"), may attract able persons to serve as
Nonemployee Directors and to provide a means whereby Nonemployee Directors can
acquire and maintain stock ownership, thereby strengthening their concern for
the welfare of the Company and its Affiliates. A further purpose of the Plan is
to provide such individuals with additional incentive and reward opportunities
designed to enhance the profitable growth of the Company and its Affiliates.
Accordingly, the Plan provides for the granting of Options to Nonemployee
Directors as provided herein.

                                II. DEFINITIONS

         The following definitions shall be applicable throughout the Plan
unless specifically modified by any paragraph:

         (a) "AFFILIATE" means any corporation, partnership, limited liability
company or partnership, association, trust or other organization which, directly
or indirectly, controls, is controlled by, or is under common control with, the
Company.

         (b) "BOARD" means the Board of Directors of the Company.

         (c) "CODE" means the Internal Revenue Code of 1986, as amended.
Reference in the Plan to any section of the Code shall be deemed to include any
amendments or successor provisions to such section and any regulations under
such section.

         (d) "COMMITTEE" means a committee of the Board that is selected by the
Board as provided in Paragraph IV(a).

         (e) "COMMON STOCK" means the common stock, par value $.01 per share, of
the Company, or any security into which such common stock may be changed by
reason of any transaction or event of the type described in Paragraph VIII.

         (f) "COMPANY" means BMC Software, Inc., a Delaware corporation.

         (g) "CORPORATE CHANGE" shall have the meaning assigned to such term in
Paragraph VIII(c) of the Plan.

         (h) "FAIR MARKET VALUE" means, as of any specified date, the mean of
the high and low sales prices of the Common Stock (i) reported on the stock
exchange composite tape on that date or (ii) if the Common Stock is not listed
on a national stock exchange, reported by the National Market System of NASDAQ
on that date (or such other reporting service approved by the Committee); or, in
either case, if no prices are reported on that date, on the last preceding

date on which such prices of the Common Stock are so reported. If the Common
Stock is traded over the counter at the time a determination of its fair market
value is required to be made hereunder, its fair market value shall be deemed to
be equal to the average between the reported high and low or closing bid and
asked prices of Common Stock on the most recent date on which Common Stock was
publicly traded. In the event Common Stock is not publicly traded at the time a
determination of its value is required to be made hereunder, the determination
of its fair market value shall be made by the Committee in such manner as it
deems appropriate.

and a Nonemployee Director with respect to an Option.

Option Plan, as amended from time to time.

         (n) "RULE 16b-3" means SEC Rule 16b-3 promulgated under the 1934 Act,
as such may be amended from time to time, and any successor rule, regulation or
statute fulfilling the same or a similar function.

term in Paragraph VII(d) of the Plan.

                  III. EFFECTIVE DATE AND DURATION OF THE PLAN

         The Plan shall become effective upon the date of its adoption by the
Board, provided the Plan is approved by the stockholders of the Company within
12 months thereafter. Notwithstanding any provision in the Plan or in any Option
Agreement, no Option shall be exercisable prior to such stockholder approval. No
further Options may be granted under the Plan after 10 years from the date the
Plan is adopted by the Board. The Plan shall remain in effect until all Options
granted under the Plan have been exercised or expired.

                               IV. ADMINISTRATION

         (a) COMPOSITION OF COMMITTEE. The Plan shall be administered by a
committee of, and appointed by, the Board that shall be comprised solely of two
or more nonemployee directors (within the meaning of the term "Non-Employee
Director" as defined in Rule 16b-3).

         (b) POWERS. Subject to the express provisions of the Plan, the
Committee shall have authority, in its discretion, to determine which
Nonemployee Directors shall receive an Option, the time or times when such
Option shall be granted, and the number of shares to be subject to each Option.
In making such determinations, the Committee shall take into account the nature
of the services rendered by the respective Nonemployee Directors, their present
and potential

                                      -2-
<PAGE>

contribution to the Company's success and such other factors as the Committee in
its discretion shall deem relevant.

         (c) ADDITIONAL POWERS. The Committee shall have such additional powers
as are delegated to it by the other provisions of the Plan. Subject to the
express provisions of the Plan, this shall include the power to construe the
Plan and the respective Option Agreements executed hereunder, to prescribe rules
and regulations relating to the Plan, to determine the terms, restrictions and
provisions of each Option Agreement, and to make all other determinations
necessary or advisable for administering the Plan. The Committee may correct any
defect or supply any omission or reconcile any inconsistency in the Plan or in
any Option Agreement in the manner and to the extent it shall deem expedient to
carry it into effect. The determinations of the Committee on the matters
referred to in this Paragraph IV shall be conclusive.

                V. SHARES SUBJECT TO THE PLAN; GRANT OF OPTIONS

         (a) SHARES SUBJECT TO THE PLAN. Subject to adjustment in the same
manner as provided in Paragraph VIII with respect to shares of Common Stock
subject to Options then outstanding, the aggregate number of shares of Common
Stock that may be issued under the Plan shall not exceed 1,000,000 shares.
Shares shall be deemed to have been issued under the Plan only (i) to the extent
actually issued and delivered pursuant to an Option or (ii) to the extent an
Option is settled in cash. To the extent that an Option lapses or the rights of
its holder terminate, any shares of Common Stock subject to such Option shall
again be available for the grant of an Option under the Plan.

         (b) GRANT OF OPTIONS. The Committee may from time to time grant Options
to one or more Nonemployee Directors determined by it to be eligible for
participation in the Plan in accordance with the terms of the Plan.

         (c) STOCK OFFERED. Subject to the limitations set forth in Paragraph
V(a), the stock to be offered pursuant to the grant of an Option may be
authorized but unissued Common Stock or Common Stock previously issued and
outstanding and reacquired by the Company. Any of such shares which remain
unissued and which are not subject to outstanding Options at the termination of
the Plan shall cease to be subject to the Plan but, until termination of the
Plan, the Company shall at all times make available a sufficient number of
shares to meet the requirements of the Plan.

                                VI. ELIGIBILITY

         Options may be granted only to persons who, at the time of grant, are
Nonemployee Directors. An Option may be granted on more than one occasion to the
same person.

                               VII. OPTION TERMS

         (a) OPTION PERIOD. The term of each Option shall be as specified by the
Committee at the date of grant, but in no event shall an Option be exercisable
after the expiration of 10 years from the date of grant.

                                      -3-
<PAGE>

         (b) LIMITATIONS ON EXERCISE OF OPTION. An Option shall be exercisable
in whole or in such installments and at such times as determined by the
Committee.

         (c) NO INCENTIVE STOCK OPTIONS. Options granted under the Plan shall
not be treated as incentive stock options within the meaning of section 422(b)
of the Code.

         (d) OPTION AGREEMENT. Each Option shall be evidenced by an Option
Agreement in such form and containing such provisions not inconsistent with the
provisions of the Plan as the Committee from time to time shall approve. Each
Option Agreement shall specify the effect of termination of membership on the
Board on the exercisability of the Option. An Option Agreement may provide for
the payment of the option price, in whole or in part, by the delivery of a
number of shares of Common Stock (plus cash if necessary) having a Fair Market
Value equal to such option price. Moreover, an Option Agreement may provide for
a "cashless exercise" of the Option by establishing procedures satisfactory to
the Committee with respect thereto. Further, an Option Agreement may provide for
the surrender of the right to purchase shares under the Option in return for a
payment in cash or shares of Common Stock or a combination of cash and shares of
Common Stock equal in value to the excess of the Fair Market Value of the shares
with respect to which the right to purchase is surrendered over the option price
therefor ("Stock Appreciation Rights"), on such terms and conditions as the
Committee in its sole discretion may prescribe. The terms and conditions of the
respective Option Agreements need not be identical. Subject to the consent of
the holder of an Option, the Committee may, in its sole discretion, amend an
outstanding Option Agreement relating to such Option from time to time in any
manner that is not inconsistent with the provisions of the Plan (including,
without limitation, an amendment that accelerates the time at which the Option,
or a portion thereof, may be exercisable).

         (e) OPTION PRICE AND PAYMENT. The price at which a share of Common
Stock may be purchased upon exercise of an Option shall be determined by the
Committee but, subject to adjustment as provided in Paragraph VIII, such
purchase price shall not be less than the Fair Market Value of a share of Common
Stock on the date such Option is granted. The Option or portion thereof may be
exercised by delivery of an irrevocable notice of exercise to the Company, as
specified by the Committee. The purchase price of the Option or portion thereof
shall be paid in full in the manner prescribed by the Committee.

         (f) RESTRICTIONS ON REPRICING OF OPTIONS. Except as provided in
Paragraph VIII, the Committee may not, without approval of the stockholders of
the Company, amend any outstanding Option Agreement to lower the option price
(or cancel and replace any outstanding Option Agreement with Option Agreements
having a lower option price).

         (g) STOCKHOLDER RIGHTS AND PRIVILEGES. The holder of an Option shall be
entitled to all the privileges and rights of a stockholder only with respect to
such shares of Common Stock as have been purchased under the Option and for
which certificates of stock have been registered in such holder's name.

         (h) OPTIONS AND RIGHTS IN SUBSTITUTION FOR OPTIONS GRANTED BY OTHER
ENTITIES. Options and Stock Appreciation Rights may be granted under the Plan
from time to time in substitution for options held by individuals providing
services to corporations or other entities

                                      -4-
<PAGE>

who become Nonemployee Directors as a result of a merger or consolidation or
other business transaction with the Company or any Affiliate.

                    VIII. RECAPITALIZATION OR REORGANIZATION

         (a) NO EFFECT ON RIGHT OR POWER. The existence of the Plan and the
Options granted hereunder shall not affect in any way the right or power of the
Board or the stockholders of the Company to make or authorize any adjustment,
recapitalization, reorganization or other change in the Company's or any
Affiliate's capital structure or its business, any merger or consolidation of
the Company or any Affiliate, any issue of debt or equity securities ahead of or
affecting Common Stock or the rights thereof, the dissolution or liquidation of
the Company or any Affiliate or any sale, lease, exchange or other disposition
of all or any part of its assets or business or any other corporate act or
proceeding.

         (b) SUBDIVISION OR CONSOLIDATION OF SHARES; STOCK DIVIDENDS. The shares
with respect to which Options may be granted are shares of Common Stock as
presently constituted, but if, and whenever, prior to the expiration of an
Option theretofore granted, the Company shall effect a subdivision or
consolidation of shares of Common Stock or the payment of a stock dividend on
Common Stock without receipt of consideration by the Company, the number of
shares of Common Stock with respect to which such Option may thereafter be
exercised (i) in the event of an increase in the number of outstanding shares
shall be proportionately increased, and the purchase price per share shall be
proportionately reduced, and (ii) in the event of a reduction in the number of
outstanding shares shall be proportionately reduced, and the purchase price per
share shall be proportionately increased. Any fractional share resulting from
such adjustment shall be rounded up to the next whole share.

         (c) RECAPITALIZATIONS AND CORPORATE CHANGES. If the Company
recapitalizes, reclassifies its capital stock, or otherwise changes its capital
structure (a "recapitalization"), the number and class of shares of Common Stock
covered by an Option theretofore granted shall be adjusted so that such Option
shall thereafter cover the number and class of shares of stock and securities to
which the Nonemployee Director would have been entitled pursuant to the terms of
the recapitalization if, immediately prior to the recapitalization, the
Nonemployee Director had been the holder of record of the number of shares of
Common Stock then covered by such Option. If (i) the Company shall not be the
surviving entity in any merger or consolidation (or survives only as a
subsidiary of an entity), (ii) the Company sells, leases or exchanges or agrees
to sell, lease or exchange all or substantially all of its assets to any other
person or entity, (iii) the Company is to be dissolved and liquidated, (iv) any
person or entity, including a "group" as contemplated by Section 13(d)(3) of the
1934 Act acquires or gains ownership or control (including, without limitation,
power to vote) of more than 50% of the outstanding shares of the Company's
voting stock (based upon voting power), or (v) as a result of or in connection
with a contested election of directors, the persons who were directors of the
Company before such election shall cease to constitute a majority of the Board
(each such event is referred to herein as a "Corporate Change"), no later than
(x) 10 days after the approval by the stockholders of the Company of such
merger, consolidation, reorganization, sale, lease or exchange of assets or
dissolution or such election of directors or (y) 30 days after a Corporate
Change of the type described in clause (iv), the Committee, acting in its sole
discretion without the consent or approval of any Option holder, shall effect
one or more of the following alternatives, which

                                      -5-
<PAGE>

alternatives may vary among individual Option holders and which may vary among
Options held by any individual Option holder: (1) accelerate the time at which
Options then outstanding may be exercised so that such Options may be exercised
in full for a limited period of time on or before a specified date (before or
after such Corporate Change) fixed by the Committee, after which specified date
all unexercised Options and all rights of Option holders thereunder shall
terminate, (2) require the mandatory surrender to the Company by selected Option
holders of some or all of the outstanding Options held by such Option holders
(irrespective of whether such Options are then exercisable under the provisions
of the Plan) as of a date, before or after such Corporate Change, specified by
the Committee, in which event the Committee shall thereupon cancel such Options
and cause the Company to pay to each such holder an amount of cash per share
equal to the excess, if any, of the amount calculated in Subparagraph (d) below
(the "Change of Control Value") of the shares subject to such Option over the
exercise price(s) under such Options for such shares, or (3) make such
adjustments to Options then outstanding as the Committee deems appropriate to
reflect such Corporate Change (provided, however, that the Committee may
determine in its sole discretion that no adjustment is necessary to Options then
outstanding), including, without limitation, adjusting an Option to provide that
the number and class of shares of Common Stock covered by such Option shall be
adjusted so that such Option shall thereafter cover securities of the surviving
or acquiring corporation or other property (including, without limitation, cash)
as determined by the Committee in its sole discretion.

         (d) CHANGE OF CONTROL VALUE. For the purposes of clause (2) in
Subparagraph (c) above, the "Change of Control Value" shall equal the amount
determined in clause (i), (ii) or (iii), whichever is applicable, as follows:
(i) the per share price offered to stockholders of the Company in any such
merger, consolidation, sale of assets or dissolution transaction, (ii) the price
per share offered to stockholders of the Company in any tender offer or exchange
offer whereby a Corporate Change takes place, or (iii) if such Corporate Change
occurs other than pursuant to a tender or exchange offer, the fair market value
per share of the shares into which such Options being surrendered are
exercisable, as determined by the Committee as of the date determined by the
Committee to be the date of cancellation and surrender of such Options. In the
event that the consideration offered to stockholders of the Company in any
transaction described in this Subparagraph (d) or Subparagraph (c) above
consists of anything other than cash, the Committee shall determine the fair
cash equivalent of the portion of the consideration offered which is other than
cash.

         (e) OTHER CHANGES IN THE COMMON STOCK. In the event of changes in the
outstanding Common Stock by reason of recapitalizations, reorganizations,
mergers, consolidations, combinations, split-ups, split-offs, spin-offs,
exchanges or other relevant changes in capitalization or distributions to the
holders of Common Stock occurring after the date of the grant of any Option and
not otherwise provided for by this Paragraph VIII, such Option and the related
Option Agreement shall be subject to adjustment by the Committee at its
discretion as to the number and price of shares of Common Stock or other
consideration subject to such Option. In the event of any such change in the
outstanding Common Stock or distribution to the holders of Common Stock, or upon
the occurrence of any other event described in this Paragraph VIII, the
aggregate number of shares available under the Plan shall be appropriately
adjusted to the extent, if any, determined by the Committee, whose determination
shall be conclusive.

         (f) STOCKHOLDER ACTION. Any adjustment provided for in the above
Subparagraphs shall be subject to any required stockholder action.

         (g) NO ADJUSTMENTS UNLESS OTHERWISE PROVIDED. Except as hereinbefore
expressly provided, the issuance by the Company of shares of stock of any class
or securities convertible into shares of stock of any class, for cash, property,
labor or services, upon direct sale, upon the exercise of rights or warrants to
subscribe therefor, or upon conversion of shares or obligations of the Company
convertible into such shares or other securities, and in any case whether or not
for fair value, shall not affect, and no adjustment by reason thereof shall be
made with respect to, the number of shares of Common Stock subject to Options
theretofore granted or the purchase price per share.

                   IX. AMENDMENT AND TERMINATION OF THE PLAN

         The Board in its discretion may terminate the Plan at any time with
respect to any shares of Common Stock for which Options have not theretofore
been granted. The Board shall have the right to alter or amend the Plan or any
part thereof from time to time; provided that no change in the Plan may be made
that would impair the rights of the holder of an Option theretofore granted
without the consent of such holder, and provided, further, that the Board may
not, without approval of the stockholders of the Company, amend or delete
Paragraph VII(f).

                                X. MISCELLANEOUS

         (a) NO RIGHT TO AN OPTION. Neither the adoption of the Plan nor any
action of the Board or of the Committee shall be deemed to give a Nonemployee
Director any right to be granted an Option or any other rights hereunder except
as may be evidenced by an Option Agreement duly executed on behalf of the
Company, and then only to the extent and on the terms and conditions expressly
set forth therein. The Plan shall be unfunded. The Company shall not be required
to establish any special or separate fund or to make any other segregation of
funds or assets to assure the performance of its obligations under any Option
Agreement.

         (b) NO MEMBERSHIP RIGHTS CONFERRED. Nothing contained in the Plan shall
confer upon any individual any right with respect to continuation of membership
on the Board.

         (c) OTHER LAWS; WITHHOLDING. The Company shall not be obligated to
issue any Common Stock pursuant to any Option granted under the Plan at any time
when the shares covered by such Option have not been registered under the
Securities Act of 1933, as amended, and such other state and federal laws, rules
and regulations as the Company or the Committee deems applicable and, in the
opinion of legal counsel for the Company, there is no exemption from the
registration requirements of such laws, rules and regulations available for the
issuance and sale of such shares. No fractional shares of Common Stock shall be
delivered, nor shall any cash in lieu of fractional shares be paid. The Company
shall have the right to deduct in connection with all Options any taxes required
by law to be withheld and to require any payments required to enable it to
satisfy its withholding obligations.

         (d) NO RESTRICTION ON CORPORATE ACTION. Nothing contained in the Plan
shall be construed to prevent the Company or any Affiliate from taking any
action which is deemed by the Company or such Affiliate to be appropriate or in
its best interest, whether or not such action

                                      -7-
<PAGE>

would have an adverse effect on the Plan or any Option. No Nonemployee Director,
beneficiary or other person shall have any claim against the Company or any
Affiliate as a result of any such action.

         (e) RESTRICTIONS ON TRANSFER. An Option shall not be transferable
otherwise than (i) by will or the laws of descent and distribution, (ii)
pursuant to a qualified domestic relations order as defined by the Code or Title
I of the Employee Retirement Income Security Act of 1974, as amended, or the
rules thereunder, or (iii) with the consent of the Committee.

         (f) GOVERNING LAW. THE PLAN SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO CONFLICTS OF
LAW PRINCIPLES THEREOF.
