ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     Cliffs Drilling Company (the "Company") completed the transaction
associated with the Asset Purchase Agreement dated as of December 29, 1997 by
and among Cliffs Drilling Trinidad Offshore Limited, a Trinidad and Tobago
private limited company ("Purchaser") which is wholly owned by the Company and
one of its affiliates, Well Services (Marine) Ltd., a Trinidad and Tobago
private limited company ("Seller"), Charles A. Brash of San Fernando, Trinidad,
W.I. and Phillip A. Pollonais of San Fernando, Trinidad, W.I.

     The Purchaser acquired 2 offshore platform drilling rigs, one
self-propelled jack-up drilling/workover rig and substantially all of the assets
used in the offshore contract drilling business in Trinidad previously operated
by the Seller. The total cost of the acquisition included cash of $23.5 million
and the issuance by the Company of 437,939 shares of the Company's Common Stock,
$0.01 par value per share. An additional $3.0 million of contingent cash
consideration may be paid to the Seller if certain post-closing criteria are
met. The outcome of the contingency is not determinable at this time, and
relates to the ultimate valuation of the assets acquired. As such, the
contingent consideration, if paid, would be an adjustment to the purchase price
of the assets acquired. The purchase price was based on the fair market value of
the assets. The Company used available cash to fund the cash portion of the
purchase price.

     The 2 platform rigs and the jack-up drilling/workover rig are currently
operating under contracts in Trinidad. Substantially all of the employees of the
Seller used in its offshore business have become employees of the Company.

         1.03    PURCHASE PRICE.  The purchase price for the Assets (the

                 (A)      the sum of  FORTY-SEVEN MILLION AND NO/100 DOLLARS
($47,000,000), exclusive of value added tax, minus,

                 (B)      the amount of the Closing Adjustment, as hereinafter
defined.

         1.04    PAYMENT OF PURCHASE PRICE.  The Purchase Price shall be
payable to Seller as follows:

                 At the Closing, Purchaser shall deliver to Seller the
following:  (i) by check or wire transfer, in immediately available funds, the
amount of TWENTY THREE MILLION FIVE HUNDRED THOUSAND DOLLARS ($23,500,000) of
the Purchase Price, (ii) such number of shares of the common voting stock of
Cliffs ($.01 par value per share) which is equal to the quotient obtained (and
expressed in number of shares) by dividing $23,500,000 by the Five-Day Average
for the five (5) days immediately preceding (but not including) the Closing
Date ("Stock Portion"), less the Closing Adjustment, if any and (iii) by check
or wire transfer, the amount of value added tax required by law on the amount
of the Purchase Price, less the Closing Adjustment, if any, for payment by
Seller to the appropriate Trinidadian Governmental Body.

                 Notwithstanding the foregoing, at the Closing Purchaser shall
deliver to Seller a facsimile of the stock certificate from the stock transfer
agent of Purchaser evidencing the Stock Portion of the Purchase Price (the
"Stock Certificate") and Purchaser shall cause the Stock Certificate to be
delivered to Seller by the stock transfer agent of Purchaser in a commercially
reasonable time and manner.

         1.05    CLOSING ADJUSTMENT.  The Closing Adjustment, if any, will be
determined as follows (collectively, "Closing Adjustment"):

                 (A)      Rig 1 Adjustment.  If, prior to Closing, Seller has
not obtained the Rig 1 Increased Rate set forth in Section 1.16(A), the Stock
Portion of the Purchase Price shall be reduced at Closing by an amount of stock
equal in value to the difference between (i) the sum of EIGHTEEN THOUSAND NINE
HUNDRED FIFTY-NINE DOLLARS ($18, 959) per day being paid by Amoco for Rig 1
under the Current Contract ("Current Amoco Rate") during the Rig 1 Increased
Rate Period (as defined in Section 1.16(A)) and (ii) the Rig 1 Increased Rate
for Rig 1 during the Rig 1 Increased Rate Period.

                 (B)      Rig 2 Adjustment.  If, prior to Closing, Seller has
not obtained the Rig 2 Increased Rate set forth in Section 1.16(B), the Stock
Portion of the Purchase Price shall, in addition to any reduction set forth in
(A) above, be reduced by an amount of stock equal in value to the difference
between (i) the sum of FIVE THOUSAND SEVEN HUNDRED TWENTY-FIVE DOLLARS ($5,725)
per day being paid by Trinmar for Rig 2 under the Current Contract ("Current
Trinmar Rate") during the Rig 2 Increased Rate Period (as defined





                                     - 12 -
<PAGE>   18
in Section 1.16(B)) and (ii) the Rig 2 Increased Rate for Rig 2 during the Rig
2 Increased Rate Period.

                 (C)      Post Closing Adjustments.  If (i) at Closing, the
Stock Portion payable by Purchaser to Seller is reduced as required by the
provisions of either or both of (A) or (B) above and (ii) at anytime subsequent
to the Closing, but during the term of the current Amoco contract for Rig 1 or
the current Trinmar contract for Rig 2, as appropriate ("Current Contract(s)"),
either or both of Amoco and Trinmar increase the day rate for Rig 1 payable to
Purchaser during the Rig 1 Increased Rate Period or the day rate for Rig 2
during the Rig 2 Increased Rate Period, to a rate and on terms reasonably
acceptable to Purchaser, in its sole discretion ("Post Closing Increased
Rate"), Purchaser shall pay to Seller additional cash ("Additional Cash") as
follows:

                          (1)     With respect to Rig 1, Additional Cash in an
                                  amount equal to the difference between the
                                  Current Amoco Rate and the Post Closing
                                  Increased Rate for Rig 1, multiplied by the
                                  number of days which is the lesser of (a) the
                                  number of days in the Rig 1 Increased Rate
                                  Period or (b) the number of days from the
                                  date on which the Post Closing Increased Rate
                                  becomes effective until January 15, 1999.

                          (2)     With respect to Rig 2, Additional Cash in an
                                  amount equal to the difference between the
                                  Current Trinmar Rate and the Post Closing
                                  Increased Rate for Rig 2, multiplied by the
                                  number of days which is the lesser of (a) the
                                  number of days in the Rig 2 Increased Rate
                                  Period or (b) the number of days from the day
                                  on which the Post Closing Increased Rate
                                  becomes effective until February 8, 1999.

provided, however, that for the purposes of (1) and (2) above, the total amount
of any Additional Cash paid by Purchaser to Seller shall be adjusted to permit
Purchaser to recover, on an amortized basis over the Agreed Amortization
Period, Purchaser's good faith estimate of its losses and additional costs of
and for (a) any reduced standby rates payable by Amoco or Trinmar,
respectively, during any refurbishment work, plus (b) Purchaser's costs of
upgrading Rig 1 and Rig 2; and provided, further, that Purchaser shall never be
required to pay to Seller Additional Cash of an amount which exceeds a value
(stated in Dollars) equal to the amount of the Closing Adjustment which was
deducted from the Stock Portion of the Purchase Price at Closing.

                 (D)      Good Faith Estimate.  For the purposes of this
Section 1.05, Purchaser's "good faith estimate" shall be based on an appraisal
carried out prior to Closing (unless otherwise agreed between the Parties) by
DeHart, Hopkins & Rodriguez, of Houston, Texas, of all work required to be
performed on Rig 1 and Rig 2, respectively, and shall be conclusive, absent
manifest error.

                 (E)      Post Closing Expenses for Classification of Rig 2.
Seller and Owners agree to reimburse Purchaser for all reasonable and necessary
expenses incurred or to be incurred by Purchaser to obtain an appropriate
classification of Rig 2 by the American Bureau of Shipping ("ABS"), including
but not limited to, expenses related to satisfaction of ABS survey
recommendations and fees and expenses of ABS and any such reimbursement shall
be made by Seller and Owners within thirty (30) days after submission by
Purchaser of vouchers covering expenses for which Purchaser seeks
reimbursement.

                 (F)      Cooperation.  Seller, Owners  and Purchaser shall
cooperate with each other and utilize their internal resources in a manner
designed to minimize the fees and expenses of both Parties and their
accountants with regard to the calculation of all Closing Adjustments.

         1.06    LIMITED ASSUMPTION OF LIABILITIES.

                                           default as of the Closing Date; and

                                  (b)      the Sub-tenancy.

                                           held under a valid and binding lease
                                           or rental agreement that is in full
                                           force and effect, except that the
                                           Shore Base Facility is rented on a
                                           monthly basis and has no current
                                           written lease or rental agreement.
                                           Seller is not in default, and no
                                           notice of alleged default has been
                                           received by Seller, under any such
                                           lease or monthly tenancy and no

                                           be in default thereunder.  None of
                                           the rights of Seller under any
                                           tenancy will be impaired by the
                                           consummation of the Transactions
                                           contemplated by this Agreement,

                          As used in this Agreement,

                          (2)     No Untrue Statements.  No representation or
warranty of Seller or either of the Owners contained in this Agreement or
statement in the Seller's Disclosure Letter contains any untrue statement.  No
representation or warranty of Seller or either of the Owners contained in this
Agreement or statement in the Seller's Disclosure Letter omits to state a

light of the circumstances under which they were made, not misleading.

                          (3)     No Material Adverse Effects.  There is no
fact known to Seller or Owners which has specific application to any Seller or
the Business (other than general economic or industry conditions) and which
could have a Material Adverse Effect which has not been set forth in this
Agreement or the Seller's Disclosure Letter.

                          (4)     Seller's Disclosure Letter.  The disclosures
in the Seller's Disclosure Letter, and those in any supplement thereto, shall
relate only to the representations and warranties in the section of this
Agreement to which they expressly relate and to no other representation or
warranty in this Agreement.

                          (5)     Conflicts.  In the event of any inconsistency
between the statements in the body of this Agreement and those in the Seller's
Disclosure Letter (other than an exception expressly set forth as such in the
Seller's Disclosure Letter in relation to a specifically identified
representation or warranty), those in this Agreement shall control.

                 (U)      Investment Representations.

                          (1)     Investment.  Seller and each Owner represents
that it and he, as appropriate, are acquiring the Stock Portion for its or his
own account for investment and not with a view to, or for sale or other
disposition in connection with, any distribution of all or any part thereof,
except (i) in an offering covered by a registration statement filed with the
United States Securities and Exchange Commission under the United States
Securities Act covering the Stock Portion, or (ii) pursuant to an applicable
exemption under the United States Securities Act.  In acquiring the Stock
Portion none of Seller or either Owner is offering or selling, or will offer or
sell, for Cliffs in connection with any distribution of the Stock Portion, and
no such Seller or Owner has a participation or will participate in any such
undertaking or in any underwriting of such an undertaking except in compliance
with applicable United States federal securities laws.

                          (2)     Review and Advice.  Seller and each Owner
acknowledges that it or his representatives have been furnished with
substantially the same kind of information regarding Cliffs and its business,
assets, results of operations and financial condition as would be contained in
a registration statement prepared in connection with a public sale of Cliffs
shares which are included in the Stock Portion.  Seller and each Owner further
represents that it and he has had an opportunity to ask questions of and
receive answers from Cliffs regarding Cliffs and its





                                     - 32 -

business, assets, results of operations and financial condition and the terms
and conditions of the issuance of the Stock Portion.

                          (3)     Economic Risk.  Seller and each Owner
acknowledges that it and he can bear the economic risk of its and his
investment in the Stock Portion, and has such knowledge and experience in
financial and business matters that each is capable of evaluating the merits
and risks of an investment in the Stock Portion.

                          (4)     Unregistered Securities.  Seller and each
Owner understands that the Stock Portion, when issued, will not have been
registered pursuant to the United States Securities Act, that the Stock Portion
will be characterized as "restricted securities" under U.S. federal securities
laws, and that, under such laws and applicable regulations, the Stock Portion
cannot be sold or otherwise disposed of without registration under the United
States Securities Act or an exemption therefrom.  Seller and each Owner further
understands that, following consummation of the transactions contemplated by
this Agreement, it or he may be an "affiliate" of Cliffs for purposes of Rule
144 promulgated under the United States Securities Act.  In this regard, Seller
and each Owner represents that each has consulted with United States legal
counsel and understands the resale limitations imposed thereby and by the
United States Securities Act.  Stop transfer instructions may be issued to the

                          DISPOSE OF THE SHARES REPRESENTED BY THIS CERTIFICATE
                          IS SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN AN
                          ASSET PURCHASE AGREEMENT DATED DECEMBER ___, 1997
                          BETWEEN THE CORPORATION, WELL SERVICES (MARINE)
                          LIMITED, CHARLES A. BRASH AND PHILLIP A. POLLONAIS, A
                          COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL
                          EXECUTIVE OFFICES OF THE CORPORATION.

It is agreed and understood by Purchaser that the first legend will be removed
upon the registration of the shares represented by such certificate under the
United States Securities Act or upon delivery to Purchaser of a written opinion
of counsel, which opinion and counsel are reasonably satisfactory to Purchaser,
to the effect that such legend is not required.

         2.02    REPRESENTATIONS AND WARRANTIES OF PURCHASER.  Purchaser
represents and warrants to Seller and Owners that the following are true and
correct on and as of the Effective Date:

                 (A)      Purchaser is a company duly organized, validly
existing and in good standing under the laws of the Republic of Trinidad and
Tobago and is qualified to transact business and is in good standing as a
foreign company in the jurisdictions where it is required to qualify in order
to conduct its business as presently conducted.  Purchaser has the power and
authority to own, lease or operate the Rigs and Assets and to carry on the
Business after Closing.

                 (B)      Purchaser may execute, deliver and perform this
Agreement without the necessity of Purchaser obtaining any consent, approval,
authorization or waiver or giving any notice or otherwise, except for

                          (1)     those consents, approvals, authorizations and
waivers which have been obtained and are unconditional and in full force and
effect; and

                          (2)     notices that have been given.

                 (C)      The execution, delivery and performance of this
Agreement do not and will not

                          (1)     constitute a violation of the Memorandum and
Articles of Association of Purchaser; or

                          (2)     constitute a violation of any statute,
judgment, Order, decree or





                                     - 34 -
<PAGE>   40
regulation or rule of any court, governmental authority or arbitrator
applicable or relating to Purchaser.

                 (D)      This Agreement has been duly authorized, executed and
delivered by Purchaser.  This Agreement constitutes the legal, valid and
binding obligation of Purchaser, enforceable in accordance with its terms,
except as may be limited by bankruptcy, reorganization, insolvency and similar
laws of general application relating to, or affecting the enforcement of,
rights of creditors and subject to general principles of equity.

         2.03    RESTRICTIVE COVENANTS.

                 (A)      Reasonableness.  The Parties to this Agreement
stipulate and agree that the restraints on competition and the covenants agreed
to within this Section 2.03 are reasonable in time, geographical territory and
scope of activities affected, and that such restraints and covenants are
reasonably necessary to protect the Assets, Business and Rigs being sold to
Purchaser.

                 (B)      Covenants.  Except as provided below, each of Brash
and Pollonais agrees that, for a period of four (4) years from the Effective
Date, neither Brash nor Pollonais shall, anywhere within the territorial waters
of Trinidad and Tobago (including its Exclusive Economic Zone) ("Territory"),
without the prior written consent of the Purchaser, individually or by
association with others, directly or indirectly, through any form of ownership,
or as a director, officer, manager, partner, joint venturer, agent, employee,
consultant or otherwise engage in any business which is competitive with the
offshore oil and gas drilling and workover business conducted by the Purchaser
in the Territory, and agrees not to solicit or induce any employee of the
Purchaser to terminate his or her employment with Purchaser.

                 (C)      Remedies,  The restrictive covenants contained in
this Section 2.03 are independent of any other provision in this Agreement.
Brash and Pollonais agree that the Purchaser's remedies at law for any breach
or threat of breach by either Brash or Pollonais of the provisions of this
Section 2.03 will be inadequate and that Purchaser shall be entitled to an
injunction or injunctions to prevent breaches of the provisions of this Section
2.03 and to enforce specifically the terms and provisions of this Section 2.03
in addition to any other remedy to which it may be entitled at law or equity.
Should any provision of this Section 2.3 be adjudged to any extent invalid by
any competent tribunal, such provision will be deemed modified to the extent
necessary to make it enforceable.

                 (D)      Consideration.  Brash and Pollonais each agree that
the restrictive covenants contained in this Section 2.03 are a condition
precedent to Purchaser entering into this Agreement and purchasing the Assets
and Business from Seller and paying the Purchase Price therefor.

                 (E)      Exclusions.  Notwithstanding the foregoing, nothing
contained in this Agreement is intended to restrict Brash and Pollonais from
carrying on and operating other





                                     - 35 -
<PAGE>   41
businesses which perform oil and gas drilling and workover services on land,
from providing other products or services which are similar to those provided
by Purchaser, Cliffs or its Affiliates, or from owning and operating interests
in oil and gas concession farmouts and leases, provided they do not own any
interest in, or operate, offshore drilling or workover equipment, or provide
any similar products or services, in the Territory.

         2.04    CONSULTING AGREEMENT.  Brash agrees that for a period of
twenty-four (24) months after the Effective Date he shall act as a consultant
to the Purchaser.  In connection therewith, Brash shall perform such duties as
the Purchaser may reasonably request and shall use his best efforts to promote
the interests of the Purchaser and the Business.  In this regard, the Purchaser
agrees that it will not make unreasonable demands on Brash's time and
acknowledges that any such duties will always be subject to Brash's
availability.  Brash agrees that he shall not receive any additional
compensation for his consulting duties, and acknowledges that his consulting
services are given in partial consideration of Purchaser's agreement to
purchase the Assets and payment of the Purchase Price; provided, however,
Purchaser agrees to reimburse Brash for all reasonable amounts for hotel,
travel, entertainment and other expenses properly incurred or to be incurred by
Brash, with prior approval of any of the officers of Purchaser, in connection
with Brash's consulting services and any such reimbursement shall be made by
the Purchaser within thirty (30) days after submission to the Purchaser of
vouchers covering expenses for which Brash seeks reimbursement.

         3.02    NOTICE, PARTICIPATION AND DURATION.

                 (A)      If a claim by a third party is made against a Party
indemnified pursuant to this Article III ("Indemnitee"), and if such Indemnitee
intends to seek indemnity with respect thereto under this Article III, the
Indemnitee shall promptly, and in any event within sixty (60) days after the
assertion of any claim or the discovery of any fact upon which Indemnitee
intends to base a claim for indemnification under this Agreement ("Claim"),
notify the Party or Parties from whom indemnification is sought ("Indemnitor")
of such Claim.  In the event of any Claim, Indemnitor, at its option, may
assume (with legal counsel reasonably acceptable to the Indemnitee) the defense
of any Claim, demand, lawsuit or other proceeding in connection with the
indemnitee's Claim, and may assert any defense of Indemnitee or Indemnitor;
provided, however, that Indemnitee shall have the right at its own expense to
participate jointly with Indemnitor in the defense of any Claim, demand,
lawsuit or other proceeding in connection with the Indemnitee's Claim and
provided further that failure to give such notice shall not preclude Indemnitee
from making any Claim thereon if the failure or delay in giving such notice did
not prejudice Indemnitee.  In the event that Indemnitor elects to undertake the
defense of any Claim hereunder, Indemnitee shall cooperate with Indemnitor to
the fullest extent possible in regard to all matters relating to the Claim
(including, without limitation, corrective actions required by applicable law,
assertion of defenses and the determination, mitigation, negotiation and
settlement of all amounts, costs, actions, penalties, damages and the like
related thereto) so as to permit Indemnitor's management of same with regards
to the amount of damages by the Indemnitor hereunder.  Neither Purchaser,
Seller nor Owners shall be entitled to settle any Claim without the prior
written consent of the other, which consent shall not be unreasonably withheld.

                 (B)      No claim for indemnification under this section may
be made after the third anniversary of the Effective Date, except claims for
indemnification in respect of breaches of the representations and warranties
contained in Section 2.01(G) hereof may be made so long as any claim may be
made in respect of such matters under any applicable statute of limitations;
provided, however, that the foregoing shall not affect any claim made in good
faith prior to the date of such expiration.

INDEMNIFICATION PROVIDED IN THIS ARTICLE III SHALL BE APPLICABLE WHETHER OR NOT
NEGLIGENCE OF THE INDEMNITEE IS ALLEGED OR PROVEN.

         3.04    REIMBURSEMENT.  In the event that the Indemnitor shall
undertake, conduct or control the defense or settlement of any Claim and it is
later determined that such Claim was not a Claim for which the Indemnitor is
required to indemnify the Indemnitee under this Article III, the Indemnitee
shall reimburse the Indemnitor for all its costs and expenses with respect to
such settlement or defense, including reasonable attorneys' fees and
disbursements.

         3.05    OFFSET.  Any Purchaser Indemnitee shall have the right to
offset any amounts for which it or any other Purchaser Indemnitee is entitled
to indemnification under this Article III against any amounts payable by any
Purchaser Indemnitee pursuant to this Agreement or any Operative Document or
otherwise.

         3.06    NO THIRD PARTY BENEFICIARIES.  The foregoing indemnification
is given solely for the purpose of protecting the Parties to this Agreement and
shall not be deemed extended to, or interpreted in a manner to confer any
benefit, right or cause of action upon, any other Person.

executed and delivered, such documents and instruments and shall take, or cause
to be taken, such further or other actions as may be reasonably necessary to
transfer, assign and deliver to Purchaser or its permitted assigns the Business
(or to evidence the foregoing) and to consummate and to effect the other
Transactions expressly required to be performed by Seller and Owners hereunder.

         4.02    NO BROKER.  Seller and Purchaser represent and warrant to the
other that they have no obligation or liability to any broker or finder by
reason of the Transactions which are the subject of this Agreement.  Each of
Seller, Owners and Purchaser agree to indemnify the other against, and to hold
the others harmless from, at all times after the date hereof any and all
liabilities and expenses (including, without limitation, legal fees) resulting
from, related to or arising out of any claim by any other Person for brokerage
commissions or finder's fees, or rights to similar compensation, on account of
services purportedly rendered on behalf of Seller or Purchaser, as the case may
be, in connection with this Agreement or the Transactions contemplated hereby.

         4.03    EXPENSES.  Except as otherwise specifically provided herein,
Seller, Owners and Purchaser shall each bear their own legal fees, accounting
fees and other costs and expenses with

respect to the negotiation, execution and the delivery of this Agreement and
the consummation of the Transactions hereunder.

         4.04    ENTIRE AGREEMENT.  This Agreement, the Exhibits hereto and the
Seller's Disclosure Letter contain, and are intended by the Parties as a final
expression of, the entire agreement between Seller, Owners and Purchaser with
respect to the Transactions contemplated by this Agreement and supersedes all
prior oral or written agreements, arrangements or understandings with respect
thereto.

         4.05    DESCRIPTIVE HEADINGS.  The descriptive headings of this
Agreement are for convenience only and shall not control or affect the meaning

         4.07    GOVERNING LAW.

                 (A)      Arbitration Provisions.  Section 4.08 shall be
governed by the procedural rules of the American Arbitration Association and,
to the extent applicable, the United States





                                     - 41 -
<PAGE>   47
Federal Arbitration Act, Title 9, United States Code.

                 (B)      Securities Law Provisions.  Sections 2.01(U) and 4.23
shall be governed, construed and interpreted by the securities laws of the
United States of America, and to the extent applicable, the laws of the State
of Texas, excluding conflicts of law principles.

                 (C)      Other Provisions. Except as set forth in subsections
(A) and (B) above, this Agreement shall be governed and interpreted by and
construed in accordance with the laws of the Republic of Trinidad and Tobago
(other than the choice of law principles thereof, which would refer the
resolution of any issue to the law of a jurisdiction other than Trinidad and
Tobago).

         4.08    ARBITRATION AND DISPUTE RESOLUTION.

                 (A)      Rules.  All disputes arising in connection with this
Agreement or the purchase, sale and lease transactions contemplated hereby
(whether any such dispute arises in contract, tort, Strict Liability or
otherwise) shall be finally settled by binding arbitration under the general
Commercial Arbitration Rules of the American Arbitration Association ("AAA"),
as same is supplemented and modified by its International Arbitration Rules and
Procedures, by three arbitrators appointed in accordance with subsection (B)
below; provided, however, that Purchaser shall always have the right to seek
the intervention of the courts of Trinidad and Tobago and any other applicable
jurisdiction, either at law or in equity,  in order to protect and enforce its
rights and benefits and, seek all necessary remedies, under the provisions of
Section 2.03 to this Agreement.

                 (B)      Powers and Selection.

                          (1)     The Party that submits a dispute to the AAA
under this Agreement shall name in its submission one arbitrator.  The Party
against whom the request for arbitration is filed must select an arbitrator and
notify the other Party and the AAA of its selection within ten (10) days after
receipt of written notice from the AAA of the other Party's demand for
arbitration.  If any Party fails to notify the AAA of its selection, within ten
(10) days after written notice by the AAA to do so, the AAA is empowered to
select an arbitrator for such Party.  The two arbitrators selected by the
Parties shall mutually select a third neutral arbitrator to chair the arbitral
panel and notify the AAA of their selection within fifteen (15) days after the
appointment of the two party-appointed arbitrators.  If the arbitrators
selected by the Parties are unable to agree on a third arbitrator within such
fifteen (15) days time period, then the AAA shall appoint the third arbitrator.

                          (2)     The arbitrators shall have the power to
gather such materials, documents, information, testimony and evidence as they
deem relevant to the dispute and the Parties shall provide such materials,
documents, information, testimony and evidence requested by the arbitrators,
except to the extent that it is proprietary, subject to third-party
confidentiality restrictions or subject to an attorney-client or other legal
privilege.  Any





                                     - 42 -
<PAGE>   48
challenge to a claim of privilege or the arbitrability of any issue shall be
resolved by the arbitrators.

                 (C)      Venue.  Arbitration conducted pursuant to this
Agreement shall be held in Houston, Texas.  Judgment on any award resulting
therefrom may be entered in and enforced by any federal or state court having
jurisdiction over any of the Parties (or the assets of any of the Parties)
against whom such award is rendered, and the Parties hereby waive any claim of
immunity to such enforcement.  Any awards hereunder shall be deemed to be
non-domestic and commercial affecting foreign commerce and may also be enforced
in accordance with the provisions of the New York Convention on the Enforcement
of Foreign Arbitral Awards (1958), as adopted and codified by the United States
of America.

                 (D)      Award.  The arbitrators shall commence and conclude
the arbitration and render their award within ninety (90) days of either
Party's demand for arbitration.  The award rendered by the arbitrators shall be
the sole and exclusive remedy of the Parties regarding any claims,
counterclaims, issues or accounting arising under this Agreement or the
Transactions  contemplated  hereby  (whether  sounding  in  contract,  tort  or
otherwise).  The arbitrators may make any award of money damages or provide
specific performance or injunctive relief, including awarding interest and
attorneys' fees.  Any award shall be final and binding on the Parties and
non-appealable, and the arbitrators shall give written reasons for their award.

                 (E)      Service.  Service of any and all notices of
arbitration hereunder may be made by either Party on the other in the manner
and to the address set forth in Section 4.06  of this Agreement and service
thus made shall be taken and held to be valid personal service upon such Party
by any Party to this Agreement on whose behalf such service is made.

                 (F)      Costs.  All administrative costs of the American
Arbitration Association together with all fees and expenses of the arbitrators
shall be borne equally by the Parties and all costs, fees and expenses incident
to enforcing any award shall be charged to and borne by the Party resisting the
award.

         4.09    ASSIGNABILITY.  This Agreement shall not be assignable
otherwise than by operation of law by any Party without the prior written
consent of the other Parties, and any purported assignment by any Party without
the prior written consent of the other Parties shall be void.

         4.10    WAIVERS AND AMENDMENTS.  Any waiver of any term or condition
of this Agreement, or any amendment or supplementation of this Agreement, shall
be effective only if in writing.  A waiver of any breach or failure to enforce
any of the terms or conditions of this Agreement shall not in any way affect,
limit or waive a Party's rights hereunder at any time to enforce strict
compliance thereafter with every term or condition of this Agreement.

         4.11    THIRD PARTY RIGHTS.  Notwithstanding any other provision of
this Agreement, this





                                     - 43 -
<PAGE>   49
Agreement shall not create benefits on behalf of any Person who is not a party
to this Agreement (including, without limitation, any broker or finder,
notwithstanding the provisions of Section 4.02 hereof), and this Agreement
shall be effective only as between the Parties hereto, their successors and
permitted assigns; provided, however, that Purchaser Indemnitees and Seller
Indemnitees are intended third party beneficiaries hereof to the extent
provided in Sections 3.01 and 3.06.

         4.12    ILLEGALITIES.  In the event that any provision contained in
this Agreement shall be determined to be invalid, illegal or unenforceable in
any respect for any reason, the validity, legality and enforceability of any
such provision in every other respect and the remaining provisions of this
Agreement shall not, at the election of the Party for whose benefit the
provisions exists, be in any way impaired.

         4.13    COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, and each such counterpart hereof shall be deemed to be an
original instrument, but all such counterparts together shall constitute but
one Agreement.

         4.14    SURVIVAL; EXCLUSIVELY OF REMEDIES.  The representations and
warranties, covenants and agreements of the Parties hereto shall survive the
Closing of the Transaction contemplated by this Agreement, and the
indemnification provided by Section 3.01 shall not be the exclusive remedy
available to the Parties hereto.

         4.15    EMPLOYEES.

                 (A)      SELLER AND OWNERS WILL CAUSE THE EMPLOYMENT OF ALL
THE OFFICERS AND EMPLOYEES ("EMPLOYEES") PERFORMING SERVICES RELATING TO THE
BUSINESS TO BE TERMINATED PRIOR TO THE CLOSING DATE.  SELLER AND OWNERS  SHALL
BE JOINTLY AND SEVERALLY RESPONSIBLE FOR, AND JOINTLY AND SEVERALLY INDEMNIFY

THIS SECTION SHALL BE IN ADDITION TO THE INDEMNITY PROVIDED IN SECTION 3.01.

                 (B)      Seller will permit Purchaser to offer employment to
some or all of the Employees prior to or on the Closing Date.  Purchaser may
offer employment as of the Closing  Date to the employees listed on Exhibit

                                     - 44 -
<PAGE>   50
intended to create any claim or right on the part of any Employee of Seller or
any Affected Employee, and no such Employee or Affected Employee shall be
entitled to assert any claim or right hereunder.

                 (D)      Seller and Owners shall be jointly and severally
responsible for causing  each of the Affected Employees to be paid at the same
time each such Affected Employee receives his or her last payroll check from
Seller or any Affiliate of Seller or Owners, a cash amount equal to such

payments required under the laws of the Republic of Trinidad and Tobago.  For
periods subsequent to December 31, 1997, Affected Employees shall be subject to
the vacation policies of Purchaser, but shall be credited, for purposes of
vacation, with the seniority attained during such employee's employment by
Seller or any Affiliate of Seller or Owners.

                 (F)      Prior to the Closing Date, Seller and Owners shall be
jointly and severally responsible for causing all Employee Plans to be
terminated.  To the extent, if any, that Purchaser offers coverage under any of
its employee benefit plans to Affected Employees, Purchaser, Seller and Owners
shall cooperate to integrate such employees into the Purchaser's employee
benefits plans, with respect to those employees who elect to participate
therein.  Any Affected Employee who becomes an employee of the Purchaser on or
after the Closing Date, shall, to the extent permitted by applicable law, be
treated as a new hire and subject to the terms and conditions for coverage as
set out under such Plans as Purchaser may, in its sole option, implement in
carrying on the Business and no other, unless specifically required otherwise
under local or other applicable law.

         4.16    ACCESS TO RECORDS.

                 (A)      Following the Effective Date, Seller shall give to
Purchaser free and unrestricted access to (and the right to make copies at the
expense of Seller) the Records and to the extent that such are being purchased

         (l)     The term "Stockholders" means the persons defined as such in
the preamble to this Agreement to whom registration rights are hereby granted,
and any Qualified Transferee to whom the rights granted under this Agreement
are assigned in accordance with Section 11 hereof.

         2.      SECURITIES SUBJECT TO THIS AGREEMENT.

                 The securities entitled to the benefits of this Agreement are
the Registrable Securities.

         3.      REGISTRATION RIGHTS

         (a)     Piggy-back Registration.

                 (i)      For a period of one (1) year from the date after the
closing of the transactions contemplated by the Asset Purchase Agreement, if
the Company proposes to file a registration statement under the Securities Act
with respect to an offering by the Company for its own account or for the
account of any other Person of any class of equity security, including any
security convertible into or exchangeable for any equity security (other than a
registration statement on Forms S-4 or S-8 (or their successor forms) or filed
in connection with an exchange offer or an offering of securities solely to the
Company's existing stockholders, and other than as



                                      2
<PAGE>   3
set forth in Section 3(a)(ii) below, then the Company shall in each case give
written notice of such proposed filing to the Stockholders of Registrable
Securities at least twenty days before  the anticipated filing date, and such
notice shall offer such Stockholders the opportunity to register such number of
Registrable Securities as each such Stockholder may request (a "Piggy-back
Registration").  The Company shall use reasonable efforts to cause the managing
underwriter or underwriters of a proposed underwritten offering to permit the
Stockholders of Registrable Securities requested to be included in the
registration for such offering to include such securities in such offering on
the same terms and conditions as any similar securities of the Company included
therein.  Notwithstanding the foregoing, if the managing underwriter or
underwriters of such offering delivers an opinion to the Stockholders of
Registrable Securities that the total amount of securities which they and any
other Persons (other than the Company) intend to include in such offering is
sufficiently large to materially and adversely affect the success of such
offering, then the amount of Registrable Securities to be offered for the
accounts of Stockholders of Registrable Securities shall be reduced in inverse
order of the priority of registration rights held by holders of securities
requesting inclusion therein to the extent necessary, in the opinion of such
managing underwriter, to reduce the total amount of securities to be included
in such offering to the amount recommended by such managing underwriter;
provided, that the reduction imposed upon Stockholders of Registrable
Securities shall not be greater, on a percentage basis with respect to the
Registrable Securities requested to be included, than the reduction imposed
upon other Persons whose Piggy-back registration rights are pari passu with
those granted hereby with respect to the amount of securities requested for
inclusion in such registration.

                 (ii)     Notwithstanding anything to the contrary contained in
this Agreement, the Company shall not be required to include Registrable
Securities in any registration statement if the proposed registration is (i) a
registration of a stock option or other employee incentive compensation or
employee benefit plan or of securities issued or issuable pursuant to any such
plan, or a registration statement relating to warrants, options or shares of
capital stock granted  or to be granted or sold primarily to employees,
directors or officers of the Company, (ii) a registration of securities issued
or issuable pursuant to a stockholder reinvestment plan or other similar plan,
(iii) a registration of securities issued in exchange for any securities or any
assets of, or in connection with a merger or consolidation with, an
unaffiliated company, (iv) a registration of securities pursuant to a "rights"
or other similar plan designed to protect the Company's stockholders from a
coercive or other attempt to cause a change in control of the Company, (v) a
registration of securities filed pursuant to Rule 145 under the Securities Act
or any successor rule, or (vi) a registration of preferred stock or securities
issued in connection with any debt or preferred stock financing of the Company.

                 (iii)    The Company may withdraw any registration statement
and abandon any proposed offering initiated by the Company without the consent
of any Stockholder of Registrable Securities, notwithstanding the request of
any such Stockholder to participate therein in accordance with this provision,
if the Company determines in its sole discretion that such action is in the
best interests of the Company and its stockholders (for this purpose, the
interest of the Stockholders shall not be considered).

         (b)     Shelf Registration.

                 The Company shall file a "shelf" registration statement on any
appropriate form pursuant to Rule 415 (or any similar rule that may be adopted
by the Commission) under the Securities Act, as promptly as practicable and in
no event later than sixty (60) calendar days after





                                       3
<PAGE>   4
the closing of the transactions contemplated by the Asset Purchase Agreement.
The Company agrees to use its best efforts to cause such shelf registration
statement to become effective as promptly as practicable after the filing
thereof and thereafter to keep it continuously effective, for a period of one
(1) year from the date after the closing of the transactions contemplated by
the Asset Purchase Agreement.  Notwithstanding anything herein to the contrary,
the period during which the Company is obligated to maintain the effectiveness
of a registration statement hereunder will terminate when all the Registrable
Securities covered by the registration statement have been sold.

         4.      REGISTRATION PROCEDURES.

                 In connection with the Company's Piggy-back or shelf
registration obligations pursuant to Section 3 hereof, the Company shall as
expeditiously as reasonably practicable:

         (a)     Prepare and file with the Commission a registration statement
on an appropriate form under the Securities Act and use its best efforts to
cause such registration statement to become effective; provided, that before
filing a registration statement or prospectus or any amendments or supplements
thereto, the Company will furnish to the Stockholders and the underwriters, if
any, as soon as practicable, copies of all such documents proposed to be filed,
which documents will be subject to the review of the Stockholders and the
underwriters, and the Company will not file any registration statement or
amendment thereto, or any prospectus or any supplement thereto, to which the
underwriters, if any, or the holders of a majority of the Registrable
Securities shall reasonably object in light of the requirements of the
Securities Act and any other applicable laws and regulations.

         (b)     Prepare and file with the Commission such amendments and
post-effective amendments to a registration statement as may be necessary to
keep such registration statement effective for the applicable period; cause the
related prospectus to be filed pursuant to Rule 424(b) under the Securities
Act; cause such prospectus to be supplemented by any required prospectus
supplement and, as so supplemented, to be filed pursuant to Rule 424(b) under
the Securities Act; and comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement during the applicable period in accordance with the intended methods
of disposition set forth in such registration statement or supplement to such
prospectus.

         (c)     Notify the Stockholders and the managing underwriters, if any,
promptly, and (if requested by any such Person) confirm such advice in writing,
(i) when a prospectus or any prospectus supplement or post-effective amendment
has been filed, and, with respect to a registration statement or any
post-effective amendment, when the same has become effective, (ii) of any
request by the Commission for amendments or supplements to a registration
statement or related prospectus or for additional information, (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of a
registration statement or the initiation of any proceeding for that purpose,
(iv) if at my time the representations and warranties of the Company
contemplated by Section 4(l) cease to be true and correct, (v) of the receipt
by the Company of any notification with respect to the suspension or
qualification of any of the Registrable Securities for sale in any jurisdiction
or the initiation of any proceeding for such purpose, (vi) of the happening of
any event which requires the making of any changes in a registration statement
or related prospectus so that such documents will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements





                                       4
<PAGE>   5
therein not misleading, and (vii) of the Company's reasonable determination
that a post-effective amendment to a registration statement would be
appropriate or that there exist circumstances not yet disclosed to the public
which make further sales under such registration statement inadvisable pending
such disclosures and post-effective amendment.

         (d)     Exercise its best efforts to obtain the withdrawal of any
order suspending the effectiveness of a registration statement, or the lifting
of any suspension of the qualification of any of the Registrable Securities for
sale in any jurisdiction, at the earliest possible moment.

         (e)     If requested by the managing underwriters or the holders of a
majority of the Registrable Securities in connection with an underwritten
offering, promptly incorporate in a prospectus supplement or post-effective
amendment such information as the managing underwriters and the holders of a
majority of the Registrable Securities agree should be included therein
relating to such sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of shares of
Registrable Securities being sold to such underwriters and the purchase price
being paid therefor by such underwriters and with respect to any other terms of
the underwritten (or best efforts underwritten) offering of the Registrable
Securities to be sold in such offering; make all required filings of such
prospectus supplement or post-effective amendment as soon as notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment; and supplement or make amendments to any registration statement if
requested by the holders of a majority of the Registrable Securities or any
underwriter of such Registrable Securities.

         (f)     Furnish to the Stockholders and each managing underwriter, if
any, without charge, at least one signed copy of the registration statement,
any post-effective amendment thereto, including financial statements and
schedules, all documents incorporated therein by reference and all exhibits
(including those incorporated by reference).

         (g)     Deliver without charge to the Stockholders and the
underwriters, if any, as many copies of the prospectus or prospectuses
(including each preliminary prospectus) and any amendment or supplement thereto
as such Persons may reasonably request; and the Company consents to the use of
such prospectus or any amendment or supplement thereto by the Stockholders and
the underwriters, if any, in connection with the offer and sale of the
Registrable Securities covered by such prospectus or any amendment or
supplement thereto.

         (h)     Prior to any public offering of Registrable Securities,
register or qualify or cooperate with the Stockholders, the underwriters, if
any, and respective counsel in connection with the registration or
qualification of such Registrable Securities for offer and sale under the
securities or blue sky laws of such jurisdictions as the Stockholders or an
underwriter reasonably requests in writing; keep each such registration or
qualification effective during the period such registration statement is
required to be kept effective and do any and all other acts or things necessary
or advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by the applicable registration statement; provided, however,
that the Company will not be required in connection therewith or as a condition
thereto to qualify generally to do business or subject itself to general
service of process in any such jurisdiction where it is not then so subject.

         (i)     Cooperate with the Stockholders and the managing underwriters,
if any, to facilitate the timely preparation and delivery of certificates
representing Registrable Securities to be sold and not bearing any restrictive
legends; and enable such Registrable Securities to be in





                                       5
<PAGE>   6
such denominations and registered in such names as the managing underwriters
may request at least two business days prior to any sale of Registrable
Securities to the underwriters.

         (j)     Use its best efforts to cause the Registrable Securities
covered by the applicable registration statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
if any, to consummate the disposition of such Registrable Securities.

         (k)     Upon the occurrence of any event contemplated by Section 4(c)
(ii) - (vii) above, prepare a supplement or post-effective amendment to the
applicable registration statement or related prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to the purchaser of the Registrable Securities being
sold thereunder, such prospectus will not contain an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein not misleading.

         (l)     Enter into such agreements (including an underwriting
agreement) and take all such other actions in connection therewith in order to
expedite or facilitate the disposition of such Registrable Securities and in
such connection, whether or not an underwriting agreement is entered into and
whether or not the Registrable Securities to be covered by such registration
are to be offered in an underwritten offering: (i) make such representations
and warranties to the Stockholders with respect to the registration statement,
prospectus and documents incorporated by reference, if any, in form, substance
and scope as are customarily made by issuers to underwriters in underwritten
offerings and confirm the same if and when requested; (ii) obtain opinions of
counsel to the Company and updates thereof with respect to the registration
statement and the prospectus in the form, scope and substance which are
customarily delivered in underwritten offerings; (iii) in the case of an
underwritten offering, enter into an underwriting agreement in form, scope and
substance as is customary in underwritten offerings and obtain opinions of
counsel to the Company and updates thereof (which counsel and opinions (in
form, scope and substance) shall be reasonably satisfactory to the managing
underwriters and not reasonably objected to by the holders of a majority of the
Registrable Securities) addressed to the Stockholders and the underwriters, if
any, covering the matters customarily covered in opinions delivered in
underwritten offerings and such other matters as may be reasonably requested by
the holders of a majority of the Registrable Securities and such underwriters;
(iv) obtain "cold comfort" letters and updates thereof from the Company's
independent certified public accountants addressed to the Stockholders and the
underwriters, if any, such letters to be in customary form and covering matters
of the type customarily covered in "cold comfort" letters by accountants in
connection with underwritten offerings; (v) if any underwriting agreement is
entered into, set forth in full in such underwriting agreement the
indemnification provisions and procedures customarily included in underwriting
agreements in underwritten offerings; and (vi) deliver such documents and
certificates as may be requested by the managing underwriters, if any, and the
holders of a majority of the Registrable Securities to evidence compliance with
clause (k) above and with any customary conditions contained in the
underwriting agreement or other agreement entered into by the Company.

         (m)     Make available for inspection by a representative of the
Stockholders, any underwriter participating in any disposition pursuant to such
registration, and any attorney or accountant retained by the Stockholders or
such underwriter, all financial and other records, pertinent corporate
documents and properties of the Company, and cause the Company's officers,
directors and employees to supply all information reasonably requested by any
such representative, underwriter, attorney or accountant in connection with
such registration; provided





                                       6
<PAGE>   7
that any records, information or documents that are designated by the Company
in writing as confidential shall be kept confidential by such Persons unless
disclosure of such records, information or documents is required by applicable
law or court or administrative order.

         (n)     Otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission and make generally available to its
security holders earnings statements satisfying the provisions of Section 11(a)
of the Securities Act and Rule 158 promulgated thereunder.

         5.      CONTENTS OF REGISTRATION STATEMENT.

                 In connection with any registration of Registrable Securities,
the Company may require each Stockholder to furnish to the Company such
information regarding itself and the distribution of such securities as the
Company may from time to time reasonably request in writing.  If the Company,
in the exercise of its reasonable judgment, objects to any information relating
to the Company requested by the Stockholders or the underwriters, if any, to be
included in any registration statement or prospectus or any amendments or
supplements thereto, the Company shall not be obligated to include such
objectionable information, and the Stockholders may withdraw the Registrable
Securities from such registration, in which event the shelf registration
statement or amendment thereto shall be filed as soon as agreement with respect
to any proposed change shall be reached among the Company, the holders of a
majority of the Registrable Securities, and the managing underwriter, if any.

         6.      STAND-OFF AGREEMENT.

                 Each Stockholder agrees by acquisition of Registrable
Securities that, upon receipt of any notice from the Company of the happening
of any event of the kind described in Section  4(c)(ii)-(vii) hereof, such
Stockholder will forthwith discontinue disposition of Registrable Securities
covered by such registration statement or prospectus until the Stockholder's
receipt of copies of the supplemented or amended prospectus contemplated by
Section 4(k) hereof, or until it is advised in writing by the Company that the
use of the applicable prospectus may be resumed, and has received copies of any
additional or supplemental filings which are incorporated by reference in such
prospectus, and, if so directed by the Company, each such Stockholder will
deliver to the Company all copies, other than permanent file copies then in
such Stockholder's possession, of the prospectus covering such Registrable
Securities current at the time of receipt of such notice.  In the event the
Company shall give any such notice, the time period regarding maintaining the
effectiveness of such registration statement set forth in Section 3 shall be
extended by the number of days during the time period from and including the
date of the giving of such notice pursuant to Section 4(c) hereof to and
including the date when the Stockholders shall have (i) received the copies of
the supplemented or amended prospectus contemplated by Section 4(k) hereof, or
(ii) been advised in writing by the Company that use of the prospectus may be
resumed.

         7.      EXPENSES OF REGISTRATION.

                 In connection with a registration, filing or qualification
pursuant to Section 3 hereof, Stockholders shall pay all underwriting
commissions and discounts attributable to sales of Registrable Securities,
registration fees payable to the Commission and the New York Stock Exchange,
and fees and expenses of Stockholder's counsel.  All other expenses of a
registration, filing or qualification pursuant to Section 3 hereof, including,
without limitation, printers' and accounting fees, and the fees and
disbursements of counsel for the Company, shall be borne and





                                       7
<PAGE>   8
paid by the Company.

         8.      UNDERWRITTEN REGISTRATIONS.

                 If any of the Registrable Securities covered by any
registration under Section 3 are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the offering may be selected by the Stockholders; provided, that
such investment bankers and managers must be reasonably satisfactory to the
Company.

         9.      INDEMNIFICATION.

                 In the event any Registrable Securities are included in a
registration statement under this Agreement:

         (a)     To the extent permitted by law, the Company will indemnify and
hold harmless each Stockholder, the officers and directors of such Stockholder,
each underwriter of Registrable Securities and each other Person, if any, who
controls such Stockholder or such underwriter within the meaning of Section 15
of the Securities Act, against any losses, claims, damages, liabilities or
expenses, joint or several, to which any such Person may become subject under
the Securities Act or otherwise, insofar as such losses, claims, damages,
liabilities or expenses (or actions in respect thereof) arise out of or are
based upon (i) any untrue statement or alleged untrue statement of a material
fact contained in any registration statement under which such Registrable
Securities were registered under the Securities Act pursuant hereto, or any
post-effective amendment thereof, or any omission or alleged omission therefrom
of a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (ii) any untrue statement or alleged
untrue statement of a material fact contained in any preliminary prospectus, if
used prior to the effective date of the registration statement and not
corrected in the final prospectus, or contained in the final prospectus (as
amended or supplemented, if the Company shall have filed with the Commission
any amendment thereof or supplement thereto), or any omission or alleged
omission therefrom of a material fact required to be stated therein or
necessary to make the statements therein not misleading; and will reimburse any
such Person for any legal or other expenses reasonably incurred by such Person
in connection with investigating or defending any such loss, claim, damage,
liability or expense; provided, however, that the indemnity agreement contained
in this Section 9(a) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or expense if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld); and provided further that the Company shall not be liable in any
such case to the extent that any such loss, claim, damage, liability or expense
arises out of or is based upon any such untrue statement or omission or alleged
untrue statement or omission which has been made in said registration
statement, preliminary prospectus, prospectus or amendment or supplement or
omitted therefrom in reliance upon and in conformity with information furnished
in writing to the Company by the Stockholders or such underwriter specifically
for use in the preparation thereof.

         (b)     To the extent permitted by law, each Stockholder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each Person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act,
each underwriter and each Person who controls any underwriter within the
meaning of Section 15 of the Securities Act, against any losses, claims,
damages, liabilities or expenses, joint or several, to which the Company or any
such Person, may become subject under the Securities





                                       8
<PAGE>   9
Act or otherwise, and will reimburse the Company or any such Person for any
legal or other expenses reasonably incurred by the Company or such Person in
connection with investigating or defending any such loss, claim, damage,
liability or expense, but only insofar as such losses, claims, damages,
liabilities or expenses (or actions in respect thereof) arise out of or are
based upon any untrue statement or omission or alleged untrue statement or
omission of a material fact referred to in clause (i) or (ii) of Section 9(a)
hereof, in each case to the extent (and only to the extent) that such untrue
statement or omission or alleged untrue statement or omission was made in
reliance upon and in conformity with information furnished in writing by or on
behalf of such Stockholder specifically for use in connection with such
registration; provided, however, that the indemnity agreement contained in this
Section 9(b) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or expense if such settlement is effected without the
consent of such Stockholder, which consent shall not be unreasonably withheld.

         (c)     Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 9,
notify the indemnifying party in writing of the commencement thereof; provided,
however, that the failure to so notify the indemnifying party shall not relieve
the indemnifying party from any liability hereunder except to the extent that
the indemnifying party is actually prejudiced by such failure to give notice.
The indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, to assume the defense thereof with
counsel mutually satisfactory to the parties; provided, however, that an
indemnified party shall have the right to retain its own counsel, with the fees
and expenses to be paid by the indemnifying party, if representation of such
indemnified party by the counsel retained by the indemnifying party would be
inappropriate due to actual or potential differing interests between such
indemnified party and any other party represented by such counsel in such
proceeding.

         (d)     If the indemnification provided for in this Section 9 from the
indemnifying party is unavailable to an indemnified party hereunder in respect
of any losses, claims, damages, liabilities or expenses referred to herein,
then the indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative benefits received by the
indemnifying party and the indemnified parties, the relative fault of the
indemnifying party and indemnified parties in connection with the actions which
resulted in such losses, claims, damages, liabilities or expenses, as well as
any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified parties shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact, has been made by, or relates to information supplied by,
such indemnifying party or indemnified parties, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such action. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Section 9(c) hereof, any legal
or other fees or expenses reasonably incurred by such party in connection with
any investigation or proceeding.  The parties hereto agree that it would not be
just and equitable if contribution pursuant to this Section 9(d) were
determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to in the
immediately preceding paragraph. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such





                                       9
<PAGE>   10
fraudulent misrepresentation.

         10.     REPORTS UNDER EXCHANGE ACT.

                 With a view to making available to the Stockholders the
benefits of Rule 144 under the Securities Act and any other rule or regulation
of the Commission that may at any time permit the Stockholders to sell
securities of the Company to the public without registration, the Company
agrees, for so long as any Stockholder holds shares of Common Stock acquired by
it pursuant to the Asset Purchase Agreement, to:

         (a)     file with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act, and the rules and regulations adopted by the Commission
thereunder; and

         (b)     furnish to the Stockholders forthwith upon request (i) a
written statement by the Company as to whether it has complied with the
reporting requirements of Rule 144, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents filed by
the Company pursuant to the Exchange Act, and (iii) such other information as
may be reasonably requested in availing the Stockholders of any rule or
regulation of the Commission which permits the sale of any securities without
registration.

         11.     ASSIGNMENT OF REGISTRATION RIGHTS.

                 The right to cause the Company to register Registrable
Securities pursuant to this Agreement may not be transferred or assigned, in
whole or in part, by any Stockholder without the prior written consent of the
Company, except to a Qualified Transferee of such Stockholder.  Any such
transferring Stockholder shall notify the Company in writing at least five
business days prior to effecting any such transfer or assignment, specifying
the name and address of the Qualified Transferee(s) and identifying the
securities with respect to which such rights are being assigned.

         12.     MISCELLANEOUS.

         (a)     Successors and Assigns; No Third Party Benefit. This Agreement
shall be binding upon and inure to the benefit of the parties and their
respective permitted successors and assigns. Nothing in this Agreement, express
or implied, is intended to confer upon any party other than the parties hereto
and their respective permitted successors and assigns any rights or remedies
under or by reason of this Agreement, except as expressly provided in this
Agreement.

         (b)     Governing Law. This Agreement, and the rights and obligations
of the parties hereunder, shall be interpreted, governed by, and construed and
enforced in accordance with, the substantive laws of the State of Texas,
without giving effect to the principles of conflicts of law thereof.

         (c)     Counterparts. This Agreement may be executed by the parties
hereto in separate counterparts, each of which when so executed and delivered
shall be deemed an original, but all such counterparts shall together
constitute one and the same instrument. Each counterpart may consist of a
number of copies hereof each signed by less than all, but together signed by
all, the parties hereto.

Agreement are inserted for convenience only and are not to be considered in

         (f)     Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
(which may be generally or in a particular instance and either retroactively or
prospectively) may not be given, unless the Company has obtained the written
consent of the holders of a majority of the Registrable Securities; provided,
however, that in the event any such amendment, modification, supplement, waiver
or consent shall materially and adversely affect the rights of a single
Stockholder or a similarly situated group of Stockholders (as opposed to the

consent shall not be effective as against such Stockholder or group of
Stockholders unless approved by such Stockholder or group of Stockholders.

         (g)     Severability. If any provision or any portion of any provision
of this Agreement or the application of such provision or any portion thereof
to any Person or circumstance shall be held invalid or unenforceable, the
remaining portion of such provision, as it applies to other Persons or
circumstances and the remaining provisions, shall not be affected or impaired
thereby.

Acquisition. This Agreement supersedes all prior agreements and understandings
between the parties with respect to such subject matter.
