ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

        On November 16, 1999, Lone Star Technologies, Inc., a Delaware
corporation ("Lone Star"), and its newly-formed and wholly-owned subsidiary
Fintube Technologies, Inc., an Oklahoma corporation ("Purchaser"), executed
an asset purchase agreement for the acquisition (the "Acquisition") by
Purchaser of substantially all of the assets of Fintube Limited Partnership,
a Delaware limited partnership, and its subsidiaries ("FLP").   Certain
liabilities of FLP were excluded. The Acquisition was closed on January 3,
2000 effective as of January 1, 2000 for a base purchase price of $82 million
plus a $2.5 million adjustment for working capital and approximately $1.5
million in acquisition related expenses. The purchase price adjustments were
estimated at the closing and are expected to be adjusted on an actual,
post-closing basis by approximately March 31, 2000. The consideration for the
Acquisition was determined following a competitive bidding process in
arm's-length negotiations between Lone Star and FLP.

        The acquired business involves the design and production of finned
tubes and other products used in a variety of heat recovery applications.
Lone Star intends to operate and to use the assets acquired in the
Acquisition in substantially the same manner as they were used by FLP prior
to the Acquisition.

        Lone Star and Purchaser utilized three different sources of financing
to pay the purchase price. Lone Star used $20 million of cash that it
received from Lone Star Steel Company, a wholly owned subsidiary of Lone Star
("Lone Star Steel"), in connection with Lone Star Steel's repayment of a $20
million subordinated loan from Lone Star.  Lone Star Steel borrowed the $20
million that it repaid to Lone Star under Lone Star Steel's $90 million
revolving line of credit with the CIT Group/Business Credit, Inc., acting on
its own behalf and as agent for other banks.  Additionally, Lone Star issued
approximately $20 million of Lone Star common stock directly to the limited
partners or other beneficial owners of FLP.  Finally, Purchaser entered into
a new Credit Agreement with Bank of America, acting on its own behalf and as
agent for other banks, in connection with the Acquisition and borrowed (i)
approximately $7 million under the revolving credit facility and (ii)  $39
million under the term loan facility.

         2.2 RETAINED ASSETS. Notwithstanding the provisions of Section 2.1,

         2.3 PAYMENT OF PURCHASE PRICE. As consideration for the purchase of the
Assets, Purchaser will pay to Fintube, for the account of all of the Sellers, at
Closing, the sum of $82,000,000 (the "BASE PURCHASE Price"), plus or minus the
Estimated Base Purchase Price Adjustment specified by Section 2.4 (hereinafter
collectively referred to as the "PURCHASE PRICE"), payable as follows: either
(a) by delivery of: (i) twenty million dollars ($20,000,000) of Lone Star Common
Stock (the "STOCK CONSIDERATION"), valued at the Valuation Price (as hereafter
defined); and (ii) the balance of the Purchase Price by cashier's check or wire
transfer acceptable to Fintube (or to AyB as provided in Section 2.1); or (b) if
a Material Adverse Effect has occurred with respect to Lone Star pursuant to
Section 7.2(c), by cashier's check or wire transfer acceptable to Fintube in the
full amount of the Purchase Price; provided, however, if the issuance of the
Stock Consideration pursuant to clause (i) above would result in a Material
Adverse Effect on Lone Star for 1999 or any subsequent taxable years (such
determination to be based on a reasoned opinion of Lone Star's legal counsel or
independent public accountants), Lone Star may, at its option: (A) reduce the
Stock Consideration by removing such number of shares of Lone Star Common Stock
therefrom as is reasonably necessary to avoid the occurrence of such Material
Adverse Effect and (B) correspondingly increase the cash portion of the Purchase
Price by the Valuation Price multiplied by that number of shares of Lone Star
Common Stock removed from the Stock Consideration pursuant to this proviso. The
value of each of the shares of Lone Star Common Stock to be delivered by the
Purchaser at Closing, if any, shall be computed by dividing the sum of the
closing price of Lone Star Common Stock for thirty (30) trading days ending on
the third trading day immediately


                                       12
<PAGE>


preceding the Closing Date, by thirty (30) (the "VALUATION PRICE"). The closing
price of Lone Star Common Stock on a trading day, for purposes of this
calculation, shall be the day's last trade price as reported under New York
Stock Exchange Composite Transactions in The Wall Street Journal. Any shares of
Lone Star Common Stock issued as a part of the Purchase Price shall be delivered
to Fintube at the Closing, in the form of a Lone Star stock certificate or
certificates, registered in the name of Fintube or the Designated Recipients (as
herein defined) bearing the restrictive legends in the form of EXHIBIT 2.3(a)
attached hereto. None of the shares, if any, of Lone Star Common Stock issued as
part of the Purchase Price shall be issued in consideration of those Assets
purchased by a subsidiary of Purchaser from AyB, and all of such Assets shall be
deemed to be purchased for the cash portion of the Purchase Price. The shares of
Lone Star Common Stock to be issued as a part of the Purchase Price shall be
registered by Lone Star under the Securities Act and approved for listing on the
NSYE, pursuant to the terms of the stock registration agreement attached hereto
as EXHIBIT 2.3(b) (the "STOCK REGISTRATION AGREEMENT").

                 (a) If there is a Securities Law Exemption (as herein defined),
         Lone Star will issue the Stock Consideration: (i) to those persons
         designated by Fintube on SCHEDULE 1.1 hereto (the "DESIGNATED
         RECIPIENTS"), as the persons to whom Fintube is directing the Stock
         Consideration be paid; and(ii) in such proportions among the Designated
         Recipients as Fintube shall designate not less than five (5) business
         days prior to the Closing Date;

                 (b) If there is not a Securities Law Exemption, Lone Star will
         so advise Fintube and Fintube will remove such number of "unaccredited
         investors" (as contemplated by Rule 501 of Regulation D of the SEC)
         from the list of Designated Recipients so that Lone Star may reasonably
         determine there is a Securities Law Exemption (in which event Lone Star
         will issue the Stock Consideration to those persons on the revised list
         of Designated Recipients);

provided, however, Lone Star may: (i) round that portion of the Stock
Consideration issuable to any Designated Recipient down to the nearest whole
share to avoid the issuance of fractional shares ; and (ii) correspondingly
increase the cash portion of the Purchase Price payable to Fintube by an amount
equal to (x), the total fractional shares multiplied by (y), the Valuation
Price. For purposes hereof, there will be a Securities Law Exemption unless Lone
Star, based upon legal authority set forth in a reasoned legal opinion of Lone
Star's counsel delivered to Fintube, determines that based on the list of
Designated Recipients and the properly completed and executed Investment
Letters, as defined below, obtained by Fintube from Designated Recipients and
forwarded to Lone Star at least five (5) business days prior to the Closing
Date, that the issuance of the Stock Consideration to each such Designated
Recipient is not exempt from registration under: (i) the Securities Act of 1933
by virtue of Rule 506 of Regulation D of the SEC and (ii) any applicable state
securities law (the "SECURITIES LAW EXEMPTION").

         2.4     BASE PURCHASE PRICE ADJUSTMENT.

                 (a) The Working Capital Base Purchase Price Adjustment shall be
either: (i) the amount, if any, by which the Closing Net Working Capital exceeds
the Benchmark Net Working


                                       13
<PAGE>


Capital calculated in SCHEDULE 2.4(a), which amount will increase the Base
Purchase Price, or (ii) the amount, if any, by which Benchmark Net Working
Capital exceeds Closing Net Working Capital, which amount will decrease the Base
Purchase Price. Fintube's methodology in computing its reserves and accruals has
been reviewed by Purchaser and is acceptable to Purchaser. The IRB Debt Base
Purchase Price Adjustment shall be the amount, if any, of the IRB Debt assumed
by Purchaser on the Closing Date, which amount will decrease the Base Purchase
Price. The Working Capital Base Purchase Price Adjustment and the IRB Debt Base
Purchase Price Adjustment are collectively called the Base Purchase Price
Adjustment ("BASE PURCHASE PRICE ADJUSTMENT").

                 (b) At least four (4) business days prior to the Closing Date,
Fintube shall deliver to Lone Star a statement (the "ESTIMATED ADJUSTMENT
STATEMENT") reflecting the Sellers' best good faith estimate, after consultation
with Lone Star, of: (i) the Closing Net Working Capital; and (ii) the amount of
the Base Purchase Price Adjustment. The Estimated Adjustment Statement shall set
forth in reasonable detail the calculation of the Sellers' estimates of the
amounts referred to in clauses (i) and (ii) above and, based thereon, a
calculation of the estimated Base Purchase Price Adjustment (the "ESTIMATED BASE
PURCHASE PRICE ADJUSTMENT"). The payment to be made by the Purchaser pursuant to
Section 2.3 hereof at the Closing shall be an amount equal to the Base Purchase
Price ($82,000,000) plus or minus the Estimated Base Purchase Price Adjustment,
as the case may be.

                 (c) Within fifteen (15) days after the Closing Date, Fintube
and its independent public accountants shall prepare and deliver to all Parties
a draft of a statement (the "DRAFT CLOSING STATEMENT") consisting of the audited
balance sheet of the Business as of the Closing Date, prepared in accordance
with GAAP. The Draft Closing Statement shall set forth the Closing Net Working
Capital, as of the Closing Date. The Draft Closing Statement shall also set
forth in reasonable detail a calculation of the actual Base Purchase Price
Adjustment (the "ACTUAL BASE PURCHASE PRICE ADJUSTMENT"); and a calculation of
the post-closing payment to be paid by Purchaser to Fintube, or by Fintube to
Purchaser, as the case may be, resulting from the foregoing calculations, after
consideration of the Estimated Base Purchase Price Adjustment paid at Closing,
(the "POST-CLOSING PAYMENT"). The fees and expenses of Fintube's independent
public accountants in connection with the Draft Closing Statement shall be borne
by Fintube. Promptly after its receipt of the Draft Closing Statement, Purchaser
shall engage a "Big Five" firm of independent public accountants to review the
Draft Closing Statement and, within thirty (30) days after Purchaser's receipt
of the Draft Closing Statement, to propose such revisions therein as are
required by GAAP. Within the fifteen (15) day period immediately following
Fintube's receipt of the proposed revisions from Purchaser's independent public
accountants, Fintube and Purchaser shall meet and endeavor in good faith to
agree on the final closing statement (the "CLOSING STATEMENT"). The fees and
expenses of Purchaser's independent public accountants shall be borne by
Purchaser. If Fintube and Purchaser are unable to agree on and finalize the
Closing Statement within such fifteen (15) day period, Fintube and Purchaser
shall on such fifteenth (15th) day agree on another "Big Five" firm of
independent public accountants to review the Draft Closing Statement and the
proposed revisions thereto and, within thirty (30) days after the engagement of
such firm, to issue the Closing Statement. Such Closing Statement shall be final
and binding on Fintube and Purchaser and shall not be subject to arbitration or
further appeal. The fees and expenses of the third, mutually engaged firm of
independent public accountants shall be borne equally by Fintube and Purchaser.
Both Fintube and


                                       14
<PAGE>


Purchaser will cooperate with each of the independent public accountants and
provide such accountants with the information necessary to prepare the Closing
Statement together with the information relating thereto. Sellers and Purchaser
shall use their individual and collective best efforts to cause all such
independent public accountants to determine the Closing Statement as soon as is
reasonably practicable after the Closing. The Party owing the Post-Closing
Payment shall deliver the Post-Closing Payment by wire transfer of immediately
available funds or by any other manner reasonably acceptable to the other Party,
no later than ten (10) days after the date on which the determination of the
Post-Closing Payment is finally made.

                 (d) The Post-Closing Payment, or any unpaid portion thereof,
payable pursuant to clause (c) of this Section 2.4, shall be increased by an
amount equal to interest thereon at a rate equal to 8% per annum, compounded
annually, from the Closing Date until actually paid.

                 (e) In connection with the preparation of the Estimated
Adjustment Statement and the Draft Closing Statement, the preparing Party shall
provide the other Party (and its respective advisors and representatives), prior
to the delivery of the relevant statement, with reasonable access (in each case
subject to receipt of reasonable advance notice and during normal business
hours) to work papers related to the calculation of Estimated Base Purchase
Price Adjustment and the Actual Base Purchase Price Adjustment, and to all books
and records that are required to verify the same, and with an opportunity to
comment on the same prior to the finalization of the statement. With respect to
the Estimated Adjustment Statement, Fintube will provide such access and
opportunity to comment no later than four (4) business days prior to the Closing
Date. At all times prior to the final determination of the Post-Closing Payment,
Purchaser and Fintube will cooperate with each other in connection with matters
contemplated by this Section 2.4.

                 (f) Except to the extent Purchaser, at its option, elects to
assume the IRB Debt, Purchaser's assumption of the Assumed Liabilities (defined
below) shall not reduce the Purchase Price.

         2.5 ASSUMPTION OF LIABILITIES. On the terms and subject to the

                               Section 9.4; and

                               obligation to obtain the release at Closing of
                               Sellers' banks and bonding companies pursuant to
                               said stand-by letters of credit and bonds.

         2.6 LIABILITIES NOT ASSUMED BY THE PURCHASER. Neither Lone Star nor the
Purchaser will assume any of the following liabilities (the "RETAINED
LIABILITIES") and the Sellers will satisfy or perform when due, the Retained
Liabilities (it being agreed that if there is a conflict between Section 2.5 and
this Section 2.6, this Section 2.6 shall govern, and neither Lone Star nor
Purchaser will assume or perform any of the liabilities set forth in this
Section 2.6):

                 (a) any liabilities of the Sellers or any of their Affiliates

organized, validly existing and in good standing under the laws of the State of
Delaware, and has the requisite power and authority to own, lease and operate
its properties, to conduct the Business as it is presently being conducted, and
to enter into and perform its obligations under this Agreement. Fintube is duly
qualified to do business as a foreign limited partnership, and is in good
standing, in the State of Oklahoma and Canada, which are the only jurisdictions
where the character of the properties owned or leased by it or the nature of its
activities makes such qualification necessary. Copies of the Certificate and

Purchaser, and such copies are accurate and complete as of the date hereof.
Subsidiaries are duly organized, validly existing and in good standing under the
laws of the jurisdiction of their organization, and have the requisite power and
authority to own, lease and operate their respective properties, to conduct the
Business as it is presently being conducted, and to enter into and perform their
respective obligations under this Agreement. Each of the Subsidiaries (other
than AyB) is duly qualified to do business, and is in good standing in Oklahoma,
which is the only jurisdiction where the character of the properties owned or
leased by them or the nature of their respective activities makes such
qualification necessary.

                 (b) AUTHORITY. Fintube has full power and authority to execute
and deliver this Agreement and the Ancillary Documents, and to perform Fintube's
obligations hereunder and thereunder. The execution, delivery and performance of
this Agreement by Fintube and the Ancillary Documents by Fintube or the
Subsidiaries has been duly authorized by all necessary partnership and other
action, and no further partnership or other action is necessary on the part of
Fintube or Sellers for Fintube or the Sellers to execute and deliver this
Agreement or the Ancillary Documents, and to consummate and perform the
obligations hereunder and thereunder.

                 (c) VALIDITY AND BINDING EFFECT. This Agreement has been duly
executed and delivered on behalf of Fintube and constitutes, and each Ancillary
Document executed or to be executed by Fintube or its Subsidiaries has been, or
when executed will be, duly executed and delivered by Fintube or its
Subsidiaries, and constitutes, or when executed and delivered will constitute,
the legal, valid and binding obligation of Fintube or its Subsidiaries,
enforceable against Fintube or its Subsidiaries in accordance with its terms,
except as the same may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and general equitable principles, regardless of
whether enforceability is considered a proceeding at law or in equity.

                 (d) NO VIOLATIONS. Except as set forth in SCHEDULE 4.1(d), the
execution and delivery of this Agreement and the Ancillary Documents does not,
and the consummation of the transaction contemplated hereby and thereby and
compliance by Fintube with the provisions hereof and thereof will not, conflict
with, result in any violation of or default (with or without notice or lapse of
time or both) under, give rise to a right of termination, cancellation or
acceleration of any obligation or to the loss of a material benefit under, or
result in the creation of any Lien on any of the Assets under any provision of:
(i) the Certificate or Agreement of Limited Partnership of Fintube or any
analogous documents regarding corporate governance of each of the respective
Subsidiaries; (ii) any loan or credit agreement, note, bond, mortgage,
indenture, lease, permit, concession, franchise, license or other contract,
agreement or instrument applicable to Fintube or to any of the Subsidiaries,
other than the Bank Debt; or (iii) any United States (or to the knowledge of
Sellers, any Mexican or Canadian) judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Sellers, or any of their respective
properties or assets.

                 (e) CONSENTS AND APPROVALS. Except as set forth in SCHEDULE
4.1(e): (i) no consent, approval, order or authorization of, registration,

required by or with respect to Sellers in connection with the execution and
delivery of this Agreement or any Ancillary Document by Fintube or the

thereby, except for the filing of a pre-merger notification report by Sellers
under the HSR Act and the expiration or termination of the applicable waiting
period thereunder; and (ii) no Third Party Consent is required by or with
respect to any of the Sellers in connection with the execution and delivery of

have good and marketable title to all of the Assets, and the Assets are being
conveyed to Purchaser, free and clear of any Liens (other than Permitted Liens).
The Assets (a) in the case of Tangible Personal Property, are in good operating
condition (ordinary wear and tear excepted); and (b) constitute all of the
property, rights and assets necessary for Purchaser to own, operate, use and
enjoy the Assets and the Business for the same or similar purposes for which,
and in the same or similar manner in which, the Assets and the Business have
been owned, operated and used and enjoyed by Sellers prior to the transaction

31, 1997 and December 31, 1996 and the related audited consolidated or combined
statements of income and cash flows for Sellers for the years ended December 31,

consolidated or combined balance sheet of Sellers for the eight months ended

Except as set forth on SCHEDULE 4.1(h), and except for the omission of footnotes
and routine annual adjustments consistent with past practices that are not
material, the Sellers' Financial Statements and the Subsidiary Financial
Statements were prepared in accordance with GAAP applied on a consistent basis
during the period involved, and fairly present in all material respects the
financial position and results of operations of Fintube and the Subsidiaries as
of the date specified and the results of operations and the cash flows of
Fintube and the Subsidiaries for the period presented therein. Except as set
forth on SCHEDULE 4.1(h), or in the Sellers' Financial Statements or the
footnotes attached thereto, the statements of income included in the Sellers
Financial Statements do not contain any items of special or nonrecurring income,
and the balance sheets included in the Sellers Financial Statements do not
reflect any write-up or revaluation increasing the book value of any assets, nor
have there been any transactions since August 31, 1999 giving rise to special or
nonrecurring income or any such write-up or revaluation. Except as set forth on
SCHEDULE 4.1(h), as of the date of this Agreement, to their knowledge, none of
the Sellers have any liability or obligation of any nature (whether absolute,
accrued, contingent or otherwise) which should be reflected as a liability on
Fintube's or such Sellers' balance sheet as of the Balance Sheet Date under
GAAP, except as and to the extent: (i) reflected or reserved against in the
Sellers' Financial Statements or the Subsidiary Financial Statements; (ii)
disclosed in one or more Schedules to this Agreement; (iii) of liabilities and
obligations under this Agreement; or (iv) of liabilities and obligations
incurred in the ordinary course of the Business (none of which is a material
liability for breach of contract, breach of warranty, tort or intellectual
property right infringement) since the Balance Sheet Date. Except for the
Subsidiaries' obligations pursuant to the Bank Debt, neither Fintube nor any
Subsidiary is a guarantor, surety, co-maker or other obligor with respect to the
debt or liability of any other Person (including Fintube). All receivables
(including accounts and notes receivable, employee advances and accrued interest
receivables) of the Sellers, as reflected on the Sellers Financial Statements as

the Closing Date, are valid obligations of the respective makers thereof, have
arisen in the ordinary course of business for goods or services delivered or
rendered, are not subject to any valid defenses, counterclaims or set offs and
have been collected or are collectible in full at their recorded


                                       22

amounts in the ordinary course of business without resort to litigation or other
extraordinary collection efforts, net of all cash discounts and reserves for
doubtful accounts reflected on the Sellers Financial Statements (in the case of
receivables so reflected) or on the books of the Fintube or the applicable
Subsidiary (in the case of receivables arising since the date thereof).

                 (i) CAPITAL STRUCTURE OF THE SUBSIDIARIES. Except as set forth
in SCHEDULE 4.1(i), all of the Interests are owned of record and beneficially by
Fintube, free and clear of any and all Liens. Except as set forth in the
SCHEDULE 4.1(i), the Interests constitute all of the ownership interests in the
Subsidiaries, and there are no options or any other securities outstanding that
are convertible into, are exchangeable for, or represent a right to acquire,
interests in the Subsidiaries.

         4.1(j)(vi) shall not apply to products sold, leased, transferred,

         authorized under applicable Environmental Laws to transport such
         materials, and have been disposed of only at treatment, storage and
         disposal facilities authorized under applicable Environmental Laws to

         that now or with the passage of time could reasonably be expected to
         give rise to any obligation to investigate or remediate such conditions
         under any Environmental Laws; and

                       (xiv) Fintube has provided to Purchaser all available
         internal and available external environmental audits and studies and

complete and accurate list of all Intellectual Property Rights that are owned by
the Sellers. Except as set forth in SCHEDULE 4.1(R), Sellers hold valid and
continuing authority in connection with the use of such Intellectual Property
Rights. To Fintube's knowledge, the conduct of the businesses of Sellers, and
any Intellectual Property Right of Sellers, do not infringe any intellectual
property or any other proprietary right of any Person. None of the Sellers has
received any written notice from any other Person pertaining to or challenging
the right of Sellers to use any of the Intellectual Property Rights. To Sellers'
knowledge, there are no material Intellectual Property Rights that are necessary
for the operation or continued operation of the Assets, for which Sellers do not

Rights. Except as set forth in SCHEDULE 4.1(R), all current employees of the
Sellers have executed written agreements with one or more of Sellers, that
assign to one or more of Sellers all rights to any inventions, improvements,
discoveries, information or other Intellectual Property Rights relating to the
Business, and none of the Sellers has cause to believe such agreements would not
be enforceable. To Fintube's knowledge, no employee of Sellers is subject to any
agreement with a prior employer or other Person that in any way adversely
affects or will adversely affect the Business or the performance of the
employee's duties as an employee. Sellers have taken reasonable precautions to
protect the secrecy, confidentiality and value of their trade secrets and other
confidential intellectual property rights.

                 (s) INSURANCE. Fintube maintains insurance with financially
sound and reputable insurers, covering the Sellers, in such amounts and covering
such risks as are in accordance with normal industry practice for companies
engaged in businesses similar to those of Sellers relating to the Assets and
owning properties in the same general area in which Sellers conduct the
Business. SCHEDULE 4.1(S) sets forth a complete and accurate list of all
insurance policies that are maintained by Fintube. There is no material default
with respect to any provision contained in any policy or binder with respect to
such insurance. There are no billed but unpaid premiums past due under any such
policy or binder.

available to the Purchaser. To the knowledge of the Sellers, each of the
Contracts is a valid and binding agreement of the parties thereto, enforceable
against them in accordance with its terms. None of the Sellers are in breach or
in default of the Contracts, and to the knowledge of the Sellers, no breach or
default exits with respect to any of the other Parties to such Contracts, and no
event has occurred which, after the giving of notice or the passage of time or

SCHEDULE 4.1(T), Fintube has not received notice of any plan or intention of any
other party to any of Contracts to exercise any right of off set with respect
to, or any right to cancel or terminate any of the Contracts, and Fintube does
not know of any fact or circumstance that would justify the exercise by any such
other party of such a right other than the automatic termination of such
Contracts in accordance with their terms. Fintube does not currently
contemplate, or have reason to believe any other Person currently contemplates
any amendment or change to any of the Contracts, which amendment or change could
have a Material Adverse Effect on Fintube.

                 (u) CUSTOMERS AND SUPPLIERS. SCHEDULE 4.1(U) contains a

twenty (20) largest suppliers of the Sellers (considered as a whole), together
with the volume of purchases made from each such supplier, during 1998 and the
first nine months of 1999. To Fintube's knowledge, none of such customers or
suppliers intends to cease purchasing from, or selling to the successor to the

trespassers, nor does any person (other than the Sellers) have a lease, tenancy,
or other right of occupancy or use of any portion of the Real Property. The Real
Property has full and free access to and from public highways, streets, and
roads, and Fintube has no knowledge of any pending or threatened legal or
administrative proceeding or any other fact or condition which would limit or
result in the termination of such access. To Fintube's knowledge, there exists
no legal or administrative proceeding or court order which might in any way
impede or adversely affect the continued use of the Real Property in the manner

         Effect. All the Real Property is zoned for the various purposes for
         which such Real Property is being used, and there exists no pending or,
         to the knowledge of Fintube, threatened legal or administrative
         proceeding which might adversely affect the validity of such zoning.

         contemplated or threatened.

         the downtown Tulsa warehouse facility, there are no unpaid charges,
         debts, liabilities, claims, or obligations arising from the
         construction, occupancy, ownership, use, or operation of the Real
         Property, or the buildings, improvements, or fixtures situated thereon,
         or the business operated thereon, which could give rise to any
         mechanic's or materialmen's or other statutory lien against the Real
         Property, or the buildings, improvements, or fixtures situated thereon,
         or any part thereof, for which any of the Sellers will be responsible.

                       (v) To Sellers' knowledge, the buildings, improvements,
         and fixtures situated on the Real Property are in good condition and
         repair (ordinary wear and tear excepted).

                       (vi) Except as disclosed on SCHEDULE 4.1(V), to Sellers'
         knowledge, the Real Property is not within any area determined by the

off or written down to net realizable value in the Sellers Financial Statements.
Finished goods in such inventories conform to the applicable specifications, all
Sellers' warranties given in connection with the sales of such goods, and under
applicable laws, and are free from defects in workmanship and material.

                 (y)   SELLERS' EMPLOYEE BENEFIT PLANS.

                       (i) SCHEDULE 4.1(Y) sets forth a complete and accurate
         list of all Sellers' Employee Benefit Plans. Except for the Sellers'
         Employee Benefit Plans, neither Sellers nor any of the Subsidiaries has
         any employee benefit plans that are subject to ERISA.

                       (ii) There is no material violation of ERISA with respect
         to the filing of applicable reports, documents and notices regarding
         any Sellers' Employee Benefit Plan with any Governmental Authority or
         the furnishing of such documents to the participants or beneficiaries
         of the Sellers' Employee Benefit Plans.

                       (iii) With respect to the Sellers' Employee Benefit
         Plans, there exists no condition or set of circumstances that could
         reasonably be expected to result in liability that is reasonably likely
         to have a Material Adverse Effect on Sellers or any of the Subsidiaries
         under ERISA, the Code or any applicable law.

                       (iv) With respect to the Sellers' Employee Benefit Plans,
         individually and in the aggregate, there are no unfunded benefit
         obligations which have not been accounted for by reserves, or otherwise
         properly footnoted in accordance with GAAP, on the Sellers Financial
         Statements, that are reasonably likely to have a Material Adverse
         Effect on Sellers or any of the Subsidiaries.

                       (v) Neither Sellers nor any other Person that together
         with Sellers would be treated as a single employer under Section 414 of
         the Code, is a participant in or has ever contributed to any
         multi-employer plan within the meaning of ERISA. Sellers and all such
         other Persons have paid and discharged promptly when due all
         liabilities and obligations arising under ERISA or any provision of the
         Code of a character which if unpaid or unperformed might result in the
         imposition of a lien on the Assets.

                       (vi) The Sellers' Employee Benefit Plans have been
         maintained, in all material respects, in accordance with their terms
         and in accordance with all applicable federal and state laws, and
         neither Sellers, nor any "party in interest" or "disqualified person"
         with respect to the Sellers' Employee Benefit Plans, has engaged in any
         "prohibited transaction" within the meaning of Section 4975 of the Code
         or Section 406 of ERISA, which has or will result in any penalty or
         tax.

                       (vii) Neither the execution and delivery of this
         Agreement nor the consummation of the transaction contemplated hereby
         will result in any payment becoming due to any employee or group of
         employees of Sellers or any of the Subsidiaries.

                       (viii) Seller has made available to Purchaser accurate
         and complete copies of the Sellers' Employee Benefit Plans (and, if
         applicable, the related trust agreements) and all amendments thereto
         and any written interpretations thereof distributed to plan
         participants together with (i) the three most recent annual reports
         (Form 5500 including, if applicable, Schedule B thereto) prepared in
         connection with any Sellers' Employee Benefit Plan and (ii)

         any Sellers' Employee Benefit Plan.

                       (ix) Except as otherwise identified in SCHEDULE 4.1(Y),
         (i) no Sellers' Employee Benefit Plan is maintained in connection with
         any trust described in Section 501(c)(9) of the Code, (ii) no Sellers'
         Employee Benefit Plan is subject to Title IV of ERISA or to the minimum
         funding standards of ERISA and the Code, and (iii) no Sellers' Employee
         Benefit Plan provides post-retirement medical or health coverage except
         to the extent required by COBRA.

                       (x) Each Sellers' Employee Benefit Plan which is intended
         to be qualified under Section 401(a) of the Code is so qualified, and
         each trust forming a part thereof is exempt from federal income taxes
         pursuant to Section 501(a) of the Code. Sellers have made available to
         Purchaser accurate and complete copies of the most recent IRS
         determination letters with respect to each such Sellers' Employee
         Benefit Plan.

                       (xi) There are no pending, or to the knowledge of
         Sellers, threatened claims against any Sellers' Employee Benefit Plan
         by any current or former employee or beneficiary covered under any
         Sellers' Employee Benefit Plan (other than routine claims for benefits
         in the ordinary course).

         showing each such employee's total compensation paid to such employee
         during 1998 and 1999.

                       (iv) Except as set forth in SCHEDULE 4.1(AA), there is no
         pending or, to the knowledge of Fintube, threatened administrative or
         legal proceeding against or involving any of the Sellers by or before,
         and the Sellers are not subject to any judgment, order, writ,
         injunction, or decree of or inquiry from, the National Labor Relations

claims against any of the Sellers to return any products by reason of alleged

                 (ff) POWER OF ATTORNEY; AUTHORIZED SIGNATORS. SCHEDULE 4.1(FF)

Sellers relating to the Assets: (i) have been prepared, assembled and maintained
in accordance with usual and customary policies and procedures; and (ii) fairly

Sellers of the Assets and the Business.

                 (hh) YEAR 2000 COMPLIANCE. None of the Sellers nor the Business
will suffer a Material Adverse Effect attributable to a lack of Year 2000
Compliance in any system, process or equipment licensed or owned by any of the
Sellers. For purposes of this subsection,"YEAR 2000 COMPLIANCE" means a computer
will read and correctly interpret the year "00" as the year "2000", thus
avoiding any material failure in the computer systems of any of the Sellers due
to the inability to correctly interpret "00" or "2000". Sellers have a Year 2000
Compliance Plan which sets forth the


                                       35
<PAGE>


inventory, assessment and remediation of all hardware, software, processes and
embedded systems used by Sellers in connection with the Assets and the Business.
Sellers' Year 2000 Compliance Plan (i) encompasses the three primary areas:
business systems (both hardware and software), communications equipment and
manufacturing equipment; (ii) includes assessment (identifying systems which
need change), remediation (making changes in the software or hardware),
verification (testing the changes) and implementation of Year 2000 compliant
systems. Sellers have received written responses from each of their significant
suppliers regarding the state of their Year 2000 compliance readiness. With
respect to any significant suppliers who have identified a concern, Sellers have
addressed such concerns. None of the Sellers will suffer a Material Adverse
Effect attributable to a lack of Year 2000 compliance by any of Sellers'
significant suppliers.

                 (ii) ILLEGAL PAYMENTS. To the knowledge of Fintube, none of the
Sellers nor any director, officer, employee, or agent of any of the Sellers has,
directly or indirectly, paid or delivered any fee, commission, or other sum of
money or item of property, however characterized, to any broker, finder, agent,
government official, or other person, in the United States or any other country,
in any manner related to the Assets, or the Business, which any of the Sellers
or any such director, officer, employee, or agent knows or has reason to believe
to have been illegal under any applicable law, including the Foreign Corrupt
Practices Act and the Israeli Anti Boycott Law.

                 (jj) NOT A FOREIGN PERSON. Except as set forth on SCHEDULE
4.1(JJ), none of the Sellers is a "foreign person" within the meaning of the
Internal Revenue Code, as amended (hereinafter called the "CODE"), Sections 1445
and 7701 (i.e. none of the Sellers is a non-resident alien, foreign corporation,
foreign partnership, foreign trust or foreign estate as those terms are defined
in the Code and regulations promulgated thereunder).

                 (d) Except with the consent of Purchaser (which consent shall

otherwise become liable for or obligated to pay, any severance or termination
payments, bonuses or increases in compensation or benefits (other than payments,
bonuses or increases that are mandated by the terms of agreements existing as of
the date hereof which are described in SCHEDULE 4.1(Z) or that are paid in the
ordinary course of business, consistent with past practices), or to forgive any
indebtedness of any employee, representative, dealer, distributor or consultant,
or enter into any contract, agreement, commitment or arrangement to do any of

                 (e) Fintube will, and will cause the Sellers to, keep and

Sellers to incur or assume any Lien on any of the Assets, except for Permitted

                 (g) Fintube will, and will cause the Sellers to: (i) pay all
Taxes, assessments and other governmental charges imposed upon any of their
assets or with respect to their franchises, business, income or assets before
any penalty or interest accrues thereon; (ii) pay all claims (including claims
for labor, services, materials and supplies) that have become due and payable
and which by law have or may become a Lien upon any of their assets prior to the
time when any penalty or fine shall be incurred with respect thereto or any such
Lien shall be imposed thereon; and (iii) comply in all material respects with
the requirements of all applicable laws, rules, regulations and orders of any
Governmental Authority, obtain or take all Governmental Actions necessary in the
operation of their businesses, and comply with and enforce the provisions of all
Contracts, including paying when due all rentals, royalties, expenses and other
liabilities relating to their business or assets; provided, however, that the
Sellers may contest the imposition of any such Taxes, assessments and other
governmental charges, any such claim, or the requirements of any applicable law,
rule, regulation or order or any Contracts, if done in good faith by appropriate
proceedings and if adequate reserves are established in accordance with GAAP or
as may be determined as sufficient by Fintube's general partner.

                 (h) Fintube will, and will cause each of the Sellers at all
times to preserve and keep in full force and effect its legal existence and all
material rights and franchises.

<PAGE>


                 (i) Fintube will maintain in full force and effect the policies
or binders of insurance referred to in SCHEDULE 4.1(S).

                 (j) Fintube will not and will not permit any of the Sellers to
engage in any practice, take any action or permit by inaction any of the
representations and warranties contained in Section 4.1 to become untrue or that
might result in any of the conditions set forth in this Agreement not being
satisfied.

         5.2     ACCESS TO ASSETS, PERSONNEL AND INFORMATION.

                 (a) From the date hereof until the Closing Date, Fintube will
afford to Purchaser and the Purchaser Representatives, at Purchaser's sole risk
and expense, reasonable access to any of the assets, books and records,
contracts, employees, representatives, agents, consultants and facilities of the
Sellers, and shall, upon request, furnish to Purchaser, at Purchaser's expense,
a copy of any file, book, record, report, contract, permit, correspondence, or
other written information, document or data concerning the Assets, the Business,
or any of the Subsidiaries that is within the possession or control of any of
the Sellers.

                 (b) Purchaser and the Purchaser Representatives shall have the
right to make an environmental and physical assessment of the assets of the
Sellers and, in connection therewith, shall have the right to enter and inspect
such assets and all buildings and improvements thereon and conduct such tests,
examinations, investigations and studies as Purchaser and Fintube deem
necessary, desirable or appropriate for the preparation of engineering or other
reports relating to such assets, their condition and the presence of Hazardous
Materials. Fintube shall be provided not less than 48 hours prior notice of such
activities, and the Representatives shall have the right to witness all such
tests and investigations. Notice to Fintube shall contain a written description
of the test, examination, assessment or study contemplated by Purchaser. Fintube
shall use reasonable efforts to assist Purchaser in obtaining permission to
conduct such an assessment with respect to any property or facility which is
leased by Sellers. Purchaser shall (and shall cause the Purchaser
Representatives to) keep any data or information acquired by any such
examinations and the results of any analyses of such data and information
strictly confidential prior to the Closing Date, and prior to the Closing Date
will not (and will cause the Purchaser Representatives not to) disclose any of
such data, information or results to any Person unless otherwise required by law
or regulation, and then only after written notice to Fintube of the
determination of the need for disclosure. Purchaser shall indemnify, defend and
hold Fintube and the Sellers' Representatives harmless from and against any and
all claims to the extent arising out of or as a result of the activities of
Purchaser and the Purchaser Representatives with respect to the Assets in
connection with conducting such environmental and physical assessment, except to
the extent of and limited by the gross negligence or willful misconduct of
Fintube or any Sellers' Representative.

                 (c) Fintube will cause the Sellers' Representatives to
cooperate in all reasonable respects with Purchaser and the Purchaser
Representatives in connection with Purchaser's examinations, evaluations and
investigations described in this Section 5.2.

<PAGE>


                 (d) Except as required by law or regulation, Purchaser will not
(and will cause the Purchaser Representatives not to) use any information
obtained pursuant to this Section 5.2 for any purpose unrelated to the
consummation of the transaction contemplated by this Agreement.

         5.3 PAYMENT OF EXPENSES. Except as otherwise set forth in this
Agreement, each of Purchaser and Sellers shall bear its own expenses, including
fees of agents, representatives, counsel, financial advisors and accountants
incurred in connection with the transaction contemplated herein, whether or not
the Closing occurs. To the extent any provision of this Agreement refers to any
fee, expense or other cost to be borne by Fintube or Sellers, such expense shall
not be paid out of or credited against the cash accounts of Fintube being
acquired by Purchaser pursuant to this Agreement, but shall instead be borne out
of the proceeds receivable by Fintube from the sale of the Assets pursuant to
this Agreement.

         5.4 PUBLIC ANNOUNCEMENTS. Prior to the Closing, Fintube and Purchaser
shall consult with each other before issuing any press release or otherwise
making any public statement with respect to the transaction contemplated by this
Agreement and shall not issue any press release or make any such public
statement prior to obtaining the approval of the other Party, unless required by
applicable law or the regulations of any stock exchange on which the securities
of the disclosing Party are then listed, but only after prior notice of such
proposed publication to the other Party.

         5.5     NO SOLICITATION.

                 (a) Immediately following the execution of this Agreement,
Fintube will, and will cause the Subsidiaries and the Representatives to,
terminate any and all existing activities, discussions and negotiations with
third parties (other than Lone Star, the Purchaser and the Purchaser
Representatives) with respect to any possible transaction involving the sale of
any material portion of assets or the merger or other business combination of
any of the Sellers with or into any such third party or the sale of any of the
partnership interests in Fintube (Any existing or future proposal for any such
transaction, an "ACQUISITION PROPOSAL").

                 (b) From the date of this Agreement to the Closing Date,
Fintube will not, and will not permit the Subsidiaries or the Sellers'
Representatives to, solicit, initiate or knowingly encourage the submission of
any offer or proposal to acquire all or any material portion of the Business,
Assets (other than the transaction contemplated by this Agreement).

                 (c) From the date of the Agreement to the Closing Date, or the
date this Agreement is terminated, whichever date first occurs, Fintube will
not, and will not permit the Sellers or their Representatives to disclose any
information relating to Sellers or the Assets to any third party (other than
Purchaser, Lone Star and the Purchaser Representatives) that is considering
making or has made an Acquisition Proposal.

         5.6 ADDITIONAL ARRANGEMENTS. Subject to the terms and conditions herein
provided, each of Fintube and Purchaser shall take, or cause to be taken, all
action and shall do, or cause to be done, all things necessary, appropriate or
desirable under the HSR Act and any other applicable laws and regulations or
under applicable governing agreements, to consummate and make effective the


                                       42
<PAGE>


transaction contemplated by this Agreement, including using such Party's
reasonable efforts to obtain all necessary waivers, consents and approvals and
effecting all necessary registrations and filings. Each of Fintube and Purchaser
shall take, or cause to be taken, all action or shall do, or cause to be done,
all things necessary, appropriate or desirable to cause the covenants and
conditions applicable to the transaction contemplated hereby, to be performed or
satisfied as soon as practicable. In addition, if any Governmental Authority
shall have issued any order, decree, ruling or injunction, or taken any other
action that would have the effect of restraining, enjoining or otherwise
prohibiting or preventing the consummation of the transaction contemplated
hereby, each of Fintube and Purchaser shall use all reasonable efforts to have
such order, decree, ruling or injunction or other action declared ineffective as
soon as practicable.

         5.7 FURTHER ASSURANCES. From time to time after the Closing, each of
the Parties will execute and deliver such further instruments of conveyance and
transfer and take such other action as the other Party may reasonably request in
order more effectively to convey and transfer the Assets and to assist in
completing the transaction contemplated by this Agreement.

         5.8     EMPLOYEES.

                 (a) On the Closing Date, Sellers shall terminate each Person
who is an employee of any of the Sellers immediately prior to the Closing Date
(collectively, the "EMPLOYEES"). On the Closing Date, Purchaser shall hire each
of such terminated Employees, at the same or higher level of compensation as
paid by Sellers immediately prior to Closing. Purchaser shall not be required to
continue the employment of any such Person for any particular time period.
Sellers and Purchaser agree that as of the Closing Date, Purchaser shall assume
each Sellers' Employee Benefit Plan maintained by Sellers, including Sellers'
401(k) profit sharing plan, subject to the approval of any insurance company or
other third-party provider of the Sellers' Employee Benefit Plans. Purchaser
shall not be required to continue any Sellers' Employee Benefit Plan for any
particular time period.

                 (b) Purchaser further agrees that the Employees shall be
credited for their service with the Sellers before the Closing Date for purposes
of eligibility and vesting in the employee plans provided by Purchaser on and
after the Closing Date, including vacation, severance pay, 401(k), pension and
disability, health insurance plans, and other employee welfare benefit plans. In
determining the number of days of vacation to which Employees will be entitled,
service with the Sellers before the Closing Date shall be combined with service
with Purchaser and its Affiliates on and after the Closing Date. Purchaser shall
credit the Employees as of the Closing Date with the number of sick days which
each of such Employees would have earned as an employee of Purchaser having the
same amount of service as each of such Employees shall have with the Sellers as
of the Closing Date. The Employees' benefits under the group health plans
provided by Purchaser on and after the Closing Date shall not subject the
Employees to any new exclusions for pre-existing conditions or waiting periods,
but Purchaser may continue to impose any such exclusions and waiting periods in
effect on the Closing Date on those Employees then subject to them.

                 (c) Purchaser shall fulfill all coverage continuation
obligations imposed by Section 4980B of the Code and Section 601 of ERISA with
respect to all Employees and all former employees of Sellers who terminate
employment with Sellers on, before, or immediately after the


                                       43
<PAGE>


Closing Date, and all other individuals covered by Sellers' group health plans
who are entitled to continuation rights under the Code or ERISA, but only with
respect to claims incurred after the Closing (within the meaning of Section
5.8(e)).

                 (d) Upon adoption of Sellers' group health plans, Purchaser:
(i) shall cover all Employees covered under Sellers' group health plans and
Sellers' former employees, with continuation coverage under the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), and their
dependents (if applicable); (ii) shall provide such coverage effective as of the
Closing; (iii) shall provide benefits and reimbursements which as of the Closing
Date are no less favorable than the benefits and reimbursements afforded under
Sellers' group health plans; and (iv) shall otherwise ensure that there will be
no loss of coverage (as such term is used in COBRA) by any such employee covered
by Seller's group health plans as of the Closing or by any former employee of
Sellers with COBRA continuation coverage. Purchaser shall not be required to
continue any Sellers' group health plan for any particular time period. SCHEDULE
5.8(D) contains a list of: (i) all individuals who have elected or who are
eligible to elect COBRA continuation coverage under any of the Sellers' group
health plans; and (ii) the dates of each qualifying event and COBRA continuation
coverage periods for each such individual. Purchaser shall comply with all
provisions of federal and state law relating to the continuation of group health
plan benefits for Employees and former employees of Sellers (if applicable),
including, without limitation, provisions of COBRA continuation coverage notices
to those Employees and "qualified beneficiaries" (as defined under Code Section
4980B) who are entitled to such notices as a result of the transaction
contemplated hereby.

                 (e) Sellers will be responsible for all premiums, contributions
and other liabilities for benefits accrued and claims incurred but not yet paid
as of Closing under any employee welfare plan (as defined in Section 3(1) of
ERISA), any employee pension plan (as defined in Section 3(2) of ERISA) or any
other employee benefit plan, program or arrangement of Sellers which provides
benefits for Employees, their eligible dependents or their beneficiaries, and
for the payment of any wages and benefits accrued prior to or as of Closing
(excluding Sellers' 401(k) profit sharing plan, COBRA compliance obligations
with respect to Employees and former employees as set forth in Sections 5.8(c)
and 5.8(d) above, employee bonus plans, vacation benefits, sick leave benefits,
personal days and similar paid time off, in each such case accrued prior to
Closing and included on the Closing Statement as a current liability, which will
be assumed by Purchaser at Closing). A claim will be deemed incurred, in the
case of medical (other than hospitalization), dental or other group health plan
benefits, when the services that are the subject of the claim are performed. In
the case of hospitalization benefits, a claim will be deemed incurred on the
date that hospitalization begins, and claims for hospitalization which began
before the Closing will be the responsibility of Sellers even if such
hospitalization continues after the Closing. After the Closing and arising
solely from the employment relationship of the Employees by Purchaser, Purchaser
will be responsible with respect to all liabilities which accrue after the
Closing with respect to the Employees, including liabilities for benefits which
accrue or which become payable after the Closing pursuant to the terms of
Purchaser's benefit plans with respect to any of the Employees and which relate
to or arise from the employment of the Employees by Purchaser, which shall
include any obligation which Purchaser may have with respect to payment of any
benefits which become payable under Purchaser's benefit plans after the Closing,
and for the payment of any wages which accrue after the Closing, all severance
or other


                                       44
<PAGE>


termination related obligations to Employees which accrue after the Closing as
may be required by applicable law or otherwise, and all other obligations of any
kind whatsoever to Employees with respect to their services as employees of
Purchaser. After the Closing, Purchaser will also be responsible for all
liabilities for employee bonus plans, vacation benefits, sick leave benefits,
personal days and similar paid time off of the Employees and Sellers' former
employees, accrued prior to Closing and included on the Closing Statement as a
current liability.

                 (f) Sellers will bear the entire cost and expense of all
worker's compensation claims made by Employees related to events occurring
before the Closing Date. Purchaser will bear the entire cost and expense of all
worker's compensation claims made by Employees related to events occurring on or
after the Closing Date. From and after the Closing Date, Purchaser will allow
the return to work of any Employees who were on disability leave on the Closing
Date as a result of a work related injury or illness, in a manner consistent
with Purchaser's treatment of other similarly situated Employees, provided that
such Employees are able to perform the essential functions of their respective
jobs (with or without reasonable accommodation).

         5.9 PRORATION OF PROPERTY TAXES. Fintube and Purchaser shall adjust and
apportion all ad valorem taxes on real and personal property or other like
charges levied, assessed or imposed upon any of the Assets, all as of the
Closing Date (prorated based upon the number of days during the applicable
taxing period such Assets were owned by: (i) any of the Sellers; and (ii)
Purchaser, respectively). Should any such tax, assessment or charge be
undetermined on the Closing Date, the last determined tax, assessment or charge
shall be used for the purpose of adjustment. All adjustments shall be made at
the Closing; provided, however, if such estimated adjustment relating to ad
valorem taxes is based on the last determined tax, assessment or charge for a
prior taxing period and the actual amount of ad valorem taxes for the current
period would result in an adjustment that is greater or less than the estimated
adjustment, Purchaser may withdraw from the Escrow Account, or promptly pay to
Fintube, as appropriate, an amount equal to the difference between the estimated
amount and the actual amount of such adjustment.

         5.10 TAXES. Purchaser shall bear and pay to Fintube one half of all
applicable Mexican, Canadian, Oklahoma sales and/or use taxes (whether national,
federal, state, provincial or local) payable in connection with this Agreement.
Seller shall be responsible for remitting all applicable sales and/or use taxes
and other transfer taxes collected from Purchaser to the appropriate state
agencies. In addition, Fintube shall be responsible for any federal or state
income taxes resulting from the transaction contemplated in this Agreement.
Purchaser shall pay any Taxes or fees required to register the change of
ownership of Assets from Fintube to Purchaser. Each Party shall prepare and file
with the Internal Revenue Service, along with its federal income tax return,
Form 8594, Asset Acquisition Statement, allocating the value to the Assets,
pursuant to SCHEDULE 2.11.

         5.11 CONFIDENTIALITY. The Confidentiality Agreement shall remain in
full force and effect following the execution of this Agreement until terminated
as described therein, and is hereby incorporated herein by reference and shall
constitute a part of this Agreement for all purposes. Lone Star and Purchaser
agree to be bound by the terms of the Confidentiality Agreement. Any and all
information received by Lone Star or Purchaser pursuant to the terms and
provisions of this Agreement shall be governed by the applicable terms and
provisions of the Confidentiality


                                       45

Agreement. Fintube will, and will cause the Subsidiaries and the Representatives
to, maintain the confidentiality of, and not disclose to any third party (other
than the Subsidiaries and the Representatives) any proprietary or confidential
information of any nature whatsoever provided by Lone Star, Purchaser or the
Purchaser Representatives without the disclosing party's prior written consent.
Fintube, Lone Star and Purchaser may, however, disclose any confidential or
proprietary information to the extent (i) such information is, or becomes part
of, the public domain other than by reason of disclosure by the receiving party;
(ii) such information is or becomes available from a third party source with the
right to disclose such information; and/or (iii) disclosure is required by
applicable law or stock exchange regulation.

         5.12 AMENDMENT OF SCHEDULES. Fintube agrees that, with respect to the
representations and warranties of Fintube contained in this Agreement, Fintube
shall have the continuing obligation until the Closing to supplement or promptly
amend the Schedules with respect to any matter hereafter arising or discovered
which, if existing or known at the date of this Agreement, would have been
required to be set forth or described in the Schedules. For all purposes of this
Agreement, including without limitation for purposes of determining whether the
condition set forth in Section 7.3(a) has been fulfilled, the Schedules hereto
shall be deemed to include only that information contained therein on the date
of this Agreement, and shall be deemed to exclude all information contained in
any supplement or amendment thereto; provided, however, that if the Closing
shall occur, then all matters disclosed pursuant to any such supplement or
amendment at or prior to the Closing shall be waived, and no party shall be
entitled to make a claim thereon pursuant to the terms of this Agreement.
Without limiting any of the foregoing, Sellers shall deliver at Closing a
supplemental schedule listing all contracts entered into on or after November 1,
1999, which would have been required to be scheduled on Schedule 4.1(t) under
paragraphs (xvii) and (xviii) of Section 4.1(t) had such contracts been entered
into prior to such date.

         5.13 NONCOMPETITION. Fintube and Purchaser shall enter into a

pursuant to which Fintube shall agree not to compete, directly or indirectly,
with Purchaser in the Business for a period of sixty (60) months from the
Closing Date in the area of interest and subject to the terms set forth therein,
for no consideration other than the Purchase Price. The Non-Competition
Agreement shall be in substantially the form set forth as EXHIBIT 5.13. Nothing
herein shall prevent Fintube from owning up to five percent of the outstanding
stock of any publicly traded entity, regardless of the business in which such
entity might be engaged.

         5.14 PRODUCT LIABILITY/DISCONTINUED OPERATIONS INSURANCE. For up to
three (3) years following the Closing Date, Fintube, at its option, shall have
the right to acquire and maintain product liability/discontinued operations
insurance, to cover any claims which may be made against the Sellers relating to
events occurring prior to the Closing Date. The cost of any such insurance shall
be borne solely by Fintube. Purchaser shall reasonably assist Fintube with its
insurance requirement.

         5.15 STOCK REGISTRATION AGREEMENT. The shares of Lone Star Common Stock
to be delivered pursuant to this Agreement will be registered by Lone Star, at
its sole expense, with the Securities and Exchange Commission ( the "SEC"), as
more fully set out in the Stock Registration Agreement attached hereto as

Partners and their respective owners to sell the shares of Lone Star Common

continuing for so long as such registration statement is effective.

set forth in SECTION 2.3, such Investment Letters shall include a sufficient
number of Investment Letters from those Designated Recipients who are accredited
investors under Rule 501 of Regulation D under the Securities Act to establish
that the number of the Designated Recipients that would be classified as
unaccredited investors under Rule 501 would be less than thirty-five (35).

                 (a) At least fifteen (15) days before Closing, Fintube shall
obtain and furnish at Fintube's expense to Purchaser (or, if so requested, its
subsidiary) a commitment for title insurance ("TITLE INSURANCE") from a title
insurance company mutually acceptable to Fintube and Purchaser, (the "TITLE
COMPANY") with respect to each parcel of Real Property described on SCHEDULE

referred to as exceptions to title in the Title Binders.

                 (b) Fintube shall obtain and furnish, at Fintube's expense, to

and clear of all Liens


                                       47

except for the Permitted Liens, and providing by way of appropriate endorsements
and supplemental coverages, insurance which is available under the title
insurance regulations of the State of Oklahoma.

                 (c) If title insurance is not legally or customarily available
in a particular jurisdiction, Fintube shall obtain and furnish at Fintube's
expense to Purchaser (or, if so requested, its subsidiary) at the Closing a
title opinion in such form as is customary in such jurisdiction and reasonably
satisfactory to Purchaser (or its subsidiary).

                 (d) At least fifteen (15) days before Closing, Fintube shall

provisions), or an estoppel letter, from the Port of Catoosa (which may be
included in the form of assignment used by the Port of Catoosa) and the landlord
of the downtown Tulsa warehouse location, consenting to the assignment of the
leased Port of Catoosa real estate and the downtown Tulsa warehouse location of
the Sellers to Purchaser and, to the extent the landlord is agreeable, providing
reasonable notice of default and an opportunity to cure to Purchaser's lender,
together with a certificate of the annual rent, security deposit and term of the
lease relating to such Real Property, and the existence of no default.

                 (e) At least fifteen (15) days before Closing, Fintube shall
deliver at Fintube's expense to Purchaser current surveys (the "SURVEYS" ) of
each parcel of Real Property described in SCHEDULE 2.1(A) (other than the Real
Property in Mexico, for which the Purchaser shall obtain a current survey). Each
Survey shall be prepared by a licensed professional engineer or surveyor
acceptable to Purchaser and to the Title Company. The Surveys (including
specifically the certificate of the engineer or surveyor forming a part thereof)

                 (f) At least fifteen (15) days before Closing, Fintube shall

"TITLE OPINIONS."

                 (g) In the event any Liens appear in the Title Binders, the
Title Opinions or the Surveys, other than the Permitted Liens, that would
unreasonably interfere with the Purchaser's use of the Real Property or
materially adversely affect its value, Purchaser shall, within seven (7) days
after receipt of the Title Binder or Title Opinion and the Survey of the Real
Property covered by such Title Binder or Title Opinion and copies of all
documents referred to therein as exceptions to title, notify Sellers in writing
of such fact (the "TITLE OBJECTION") in which event Sellers shall have seven (7)

accepted all exceptions to title shown on the Title Binder, the Title Opinions
or the Surveys, except for matters which are the subject of a notification
permitted under the preceding sentence, and such exceptions shall be included in
the term "Permitted Liens" as used herein.

EXHIBIT 5.19 attached hereto. All of the Options will be for a ten-year term and
will have an exercise price equal to the fair market value of the Lone Star
Common Stock on the date of the grant. One-half of the Options (the "EMPLOYMENT
OPTIONS") will vest 25% per year over four years. The remaining one-half of the
Options (the "PERFORMANCE OPTIONS") will vest: (i) 50% on the 10th day after the
completion of an audit of the Purchaser's financial statements for the year
ended December 31, 2000, if such audit establishes that the Business achieved
EBITDA of $21,100,000 for calendar year 2000, as set forth on page 91 of the
Confidential Information Memorandum, dated February 1999 (the "PROJECTIONS");
and (ii) 50% on the 10th day after completion of an audit of the Purchaser's
financial statements for the year ended December 31, 2001, if such audit
establishes that the Business achieved EBITDA of $26,700,000 for calendar year
2001, as set forth in the Projections. If the Projections are not met by the
specified dates, the Performance Options will lapse.

         5.20 CONSULTING AGREEMENT. Purchaser and Jerry E. Ryan shall enter into
a consulting agreement in the form of EXHIBIT 5.20 hereto (the "CONSULTING
AGREEMENT");

certain legal services to Purchaser with respect to the Business after the
Closing, at customary rates.

         5.23 SURVIVAL OF COVENANTS. Except for any covenant or agreement which
by its terms expressly terminates as of the date of Closing, the covenants and
agreements of the parties hereto contained in this Agreement shall survive the
Closing, but shall expire as of the date set out in Section 9.10.

         5.24 CHANGE OF NAME. Fintube and each of the Sellers agrees to change

"Altetas y Birlos, S.A. de C.V.", "Biraghi" and "Steel Coil Services".

         5.25 CORRECTION OF ENVIRONMENTAL CONDITIONS. Between the date hereof
and the Closing Date, Sellers shall endeavor in good faith to correct fully, in
accordance with applicable law, (i) those environmental conditions requiring
short term action set forth in the interim report of ERM Southwest dated
November 10, 1999 (the "ERM REPORT") and (ii) those environmental conditions
identified by Purchaser as a result of its conducting further environmental due
diligence prior to the Closing Date that Purchaser, in consultation with ERM,
hereinafter identifies as also requiring short term

<PAGE>


action (those environmental conditions described in clauses (i) and (ii) hereof
being herein called "ENVIRONMENTAL DEFICIENCIES"). To the extent any such
Environmental Deficiency is not so corrected to the reasonable satisfaction of
Purchaser by the third business day immediately preceding the Closing Date, a
current liability reserve will be established on the financial statements of
Fintube as of the Closing Date and reflected on the Closing Statement in an
amount mutually agreed by Fintube and Purchaser to be sufficient to correct the
Environmental Deficiencies in accordance with applicable law. Notwithstanding
the foregoing, if not less than three (3) business days prior to the Closing
Date, Fintube determines that the cost of correcting the Environmental
Deficiencies and/or establishing a current liability reserve therefor is not
reasonably acceptable to Fintube, Fintube may at its option elect not to close
the transaction contemplated by this Agreement without liability to Purchaser or
Lone Star.

         5.26 LONE STAR COMMON STOCK. Within three (3) days from the date

to such files and records and the right to make copies and extracts therefrom at
any time during normal business hours, and shall not dispose of any such files

                 (c) By Purchaser if: (i) there has been a material breach of

days prior written notice of such breach, and Fintube has failed to cure such
breach within said 30 day period); or (ii) Fintube has failed to comply in any
material respect with any of its covenants or agreements contained in this
Agreement, and such failure has not been, or cannot be, cured within a
reasonable time after notice and a demand for cure thereof; or

         8.2 EFFECT OF TERMINATION. If this Agreement is terminated by either
Fintube or Purchaser pursuant to the provisions of Section 8.1, this Agreement
shall forthwith become void, and there shall be no further obligation under this
Agreement on the part of any Party or its respective Affiliates, directors,
officers, or stockholders to the other Party, except pursuant to the provisions
of Sections 5.2(d), 5.3, 5.11, 8.3 and Article X, which provisions shall remain
in full force and effect; provided, however, that the termination of this
Agreement shall not relieve either Party from any


                                       54
<PAGE>


liability for damages incurred as a result of a breach by such Party of its
representations, warranties, covenants, agreements or other obligations
hereunder, occurring prior to such termination.

         8.3 CONSEQUENTIAL DAMAGES. If this Agreement is terminated for any
reason whatsoever, neither Fintube, Lone Star or the Purchaser shall recover any
consequential, incidental or special damages from the other Party.

                                   ARTICLE IX
                           INDEMNIFICATION AND CLAIMS

         9.1 INDEMNIFICATION. After the Closing, both Fintube and Purchaser
(each an "INDEMNIFYING PARTY") hereby agrees to indemnify, defend and hold
harmless the other Party, and its directors, officers, employees and controlled
and controlling persons (hereinafter collectively "RELATED PERSONS"), from and
against all Claims asserted against, resulting to, imposed upon or incurred by
such Party or such Party's Related Persons (an "INDEMNIFIED PERSON"), subject to
all of the provisions and limitations contained in this Article IX, to the
extent resulting from: (a) the inaccuracy or breach of any representation or
warranty of the Indemnifying Party contained in or made pursuant to this
Agreement; or (b) the breach of any covenant of the Indemnifying Party contained
in or made pursuant to this Agreement. For purposes of determining whether an
Indemnified Person is entitled to indemnification under this Article IX due to
the breach of an Indemnifying Party's representation or warranty, the
materiality qualification in such representation or warranty shall be
disregarded and such representation or warranty shall be read for purposes of
this Article IX as though such qualification was not included therein (it being
agreed by the Parties that the Basket described in Section 9.7(b) hereof was
intended to supplant such materiality qualification). As used in this Article
IX, the term "CLAIM" shall include, (x) all debts, liabilities and obligations,
(y) all losses, damages, costs and expenses, including pre- and post-judgment
interest, penalties, court costs and attorneys' fees and expenses, and (z) all
demands, claims, actions, costs of investigation causes of action, proceedings,
arbitrations, judgments, settlements and assessments.

         9.2 PRE-CLOSING OPERATIONS. Fintube further hereby agrees to indemnify,
defend and hold Purchaser and Purchaser's Related Persons harmless from and
against all Claims asserted against, resulting to, imposed upon or incurred by
Purchaser with respect to any liabilities of any of the Sellers, which are not
Assumed Liabilities, (including, but not limited to, Taxes accrued by any of the
Sellers for periods (or portions thereof) ending on or before the Closing Date);
provided however, that Fintube shall have no obligation to Purchaser until the
total amount of all Purchaser Claims exceeds the Basket set forth in Section
9.7(b), except for Fintube's obligations pursuant to Section 5.9, which shall
not be subject to the Basket.

         9.3 POST-CLOSING OPERATIONS. Purchaser further hereby agrees to
indemnify, defend and hold Fintube and Fintube's Related Persons harmless from
and against all Claims asserted against, resulting to, imposed upon or incurred
by Fintube with respect to: (a) any of the Assumed Liabilities; and (b) the
ownership, operation, use or enjoyment of the Assets or the Business by
Purchaser after the Closing.

         9.4 WARRANTY CLAIMS. Product or service warranty claims (whether
arising by contract or operation of law, including any implied warranties of
merchantability or fitness for a particular purpose) relating to products or
services provided by the Business on or after the Closing Date, shall be the
sole responsibility of the Purchaser. Product or service warranty claims
(whether arising by contract or operation of law, including any implied
warranties of merchantability or fitness for a particular purpose) that relate
to products or services provided by the Business before the Closing Date shall
be the responsibility of the Purchaser (the "WARRANTY CLAIMS"); provided,
however, the Purchaser shall have the right to recover any amounts that the
Purchaser pays for such Warranty Claims, by reimbursement from the Escrow
Account, on the terms and conditions set forth below:

         (a)      The first $200,000 of Warranty Claims incurred during each of
                  the periods: (i) from the Closing Date through December 31,
                  2000 (the "2000 PERIOD"); and (ii) from January 1, 2001
                  through the date described in Section 9.10 (the "2001
                  PERIOD"), shall be the sole responsibility of the Purchaser,
                  and the Purchaser agrees to satisfy and pay said Warranty
                  Claims without reimbursement from the Escrow Account, as and
                  when the Purchaser determines, in good faith, that said
                  Warranty Claims are valid.

         (b)      Any Warranty Claims over $200,000 but less than $400,000
                  incurred during each of (i) the 2000 Period and (ii) the 2001
                  Period, shall be satisfied by the Purchaser, as and when the
                  Purchaser determines, in good faith, that said Warranty Claims
                  are valid; and Purchaser shall be entitled to assert Warranty
                  Claims against the Escrow Account for the amount of such
                  Warranty Claims, without regard to the Basket, but only to the
                  extent such Warranty Claims are agreed to be valid Warranty
                  Claims by Fintube, or if the Purchaser and Fintube are unable
                  to agree upon the validity of said Warranty Claims, the
                  arbitrator described in Section 10.12(c) shall determine the
                  validity of such Warranty Claims.

         (c)      Any Warranty Claims over $400,000 but less than $600,000
                  incurred during each of (i) the 2000 Period and (ii) the 2001
                  Period, shall be satisfied by the Purchaser, as and when the
                  Purchaser determines, in good faith, that said Warranty Claims
                  are valid; and Purchaser shall be entitled to assert such
                  Warranty Claims against the Escrow Account for one-half of the
                  amount of such Warranty Claims, without regard to the Basket,
                  but only to the extent such claims are agreed to be valid
                  Warranty Claims by Fintube, or if the Purchaser and Fintube
                  are unable to agree upon the validity of said Warranty Claims,
                  the arbitrator described in Section 10.12(c) shall determine
                  the validity of such Warranty Claims.

         (d)      Any Warranty Claims over $600,000 incurred during each of (i)
                  the 2000 Period and (ii) the 2001 Period, shall be satisfied
                  by the Purchaser, as and when the Purchaser determines, in
                  good faith, that said Warranty Claims are valid; and Purchaser
                  shall be entitled to assert such Warranty Claims against the
                  Escrow Account for the amount of such Warranty Claims, without
                  regard to the Basket, but only to the extent such claims are
                  agreed to be valid Warranty Claims by Fintube, or if the
                  Purchaser and Fintube are unable to agree upon the validity of
                  said Warranty Claims, the arbitrator described in Section
                  10.12(c) shall determine the validity of such Warranty Claims.

         (e)      On the date described in Section 9.10, the ability of the
                  Purchaser to seek reimbursement from the Escrow Account for
                  Warranty Claims shall forever terminate (other than with
                  respect to any claims for reimbursement made, but not
                  resolved, prior to such date), and after said date, the
                  Purchaser shall pay any and all Warranty Claims, without
                  reimbursement, and shall indemnify and hold Fintube harmless
                  from and against all such Warranty Claims.

         The Purchaser's sole right to recover any amounts that the Purchaser
pays for Warranty Claims shall be to seek reimbursement for such claims from the
Escrow Account.

         Purchaser and Fintube agree that after the Closing Date, Purchaser
shall handle and resolve all Warranty Claims relating to the Business, whether
occurring before or after the Closing Date. Purchaser agrees to handle and
resolve said Warranty Claims in good faith, and to use its best efforts to
minimize the expense of said Warranty Claims to the extent consistent with
reasonable business practices. Purchaser further agrees that for any Warranty
Claims, it shall not assert any charge for any employee time or corporate
overhead of the Purchaser or Lone Star in administering the Warranty Claims.
Purchaser also agrees that the expense of resolving any valid Warranty Claim
shall be limited to actual cost to the Purchaser of resolving said Warranty
Claims.

         9.5 WARN ACT. Purchaser hereby agrees that for purposes of the WARN
Act, the Closing Date shall be the "effective date" as such term is used in the
WARN Act. Purchaser acknowledges and represents that it has no present intent to
engage in a "mass layoff" or "plant closing" with respect to the Business, as
defined in the WARN Act. Purchaser agrees that the Purchaser shall be
responsible for any notification required under the WARN Act with respect to the
Business in connection with any "employment loss," as defined in the WARN Act,
that may occur on or after the Closing Date, and shall indemnify the Fintube and
Fintube's Related Persons, and shall hold the Fintube and Fintube's Related
Persons harmless from and against all fines and other payments which may become
due under the WARN Act with respect to the Business in connection with any
"employment loss," as defined in the WARN Act, that may occur on or after the
Closing Date.

         9.6 DEFENSE OF THIRD PARTY CLAIMS. In the event any Claim is asserted
against any Indemnified Person by a third party, the Indemnified Person shall
with reasonable promptness notify the Indemnifying Party of such Claim. If the
Indemnified Person does not so notify the Indemnifying Party within fifteen (15)
days after becoming aware of such Claim, then the Indemnifying Party shall, if
such delay materially prejudices the Indemnifying Party with respect to the
defense of such Claim, be relieved of liability hereunder in respect of such
Claim to the extent of the damage caused by such delay. In any such proceeding,
following receipt of notice properly given, the Indemnifying Party shall be
entitled, at its sole discretion, to assume the entire defense of such Claim
(with counsel selected by it which is reasonably satisfactory to the Indemnified
Person or Persons), and the Indemnifying Party shall bear the entire cost of
defending such Claim. The Indemnifying Party shall not have the right to settle
any such Claim without the written consent of the Indemnified Person or Persons.
In the event of the assumption of the defense by the Indemnifying Party, the
Indemnifying Party shall not be liable for any further legal or other expenses
subsequently incurred by the Indemnified Persons in connection with such defense
unless otherwise agreed to in writing by the


                                       57
<PAGE>


Indemnifying Party or as herein provided; provided, however, the Indemnified
Persons shall have the right to participate in such defense, at their own cost,
and the obligation to cooperate therewith.

         9.7     LIMIT ON INDEMNITY OBLIGATIONS.

                 (a) No Indemnified Person shall be entitled to seek
indemnification from any Indemnifying Party pursuant to this Article IX with
respect to any Claim, unless such Indemnified Person notifies such Indemnifying
Party of such Claim in writing, on or before the 15th day after the completion
of the audit of the calendar year 2001 financial statements of the Business.
Purchaser hereby agrees to use reasonable best efforts to cause the audit of the
calendar year 2001 financial statements of the Business to be completed on or
before MARCH 31, 2002. The foregoing notwithstanding, no Indemnified Person
shall be entitled to seek indemnification from any Indemnifying Party pursuant
to this Article IX, unless such claim is presented to the Indemnifying Party on
or before APRIL 15, 2002.

                 (b) If the total amount of all Claims which Purchaser, Lone
Star or any of their respective Related Persons have the right to assert against
Fintube under this Article IX (the "PURCHASER CLAIMS") does not exceed
seventy-five hundredths of one percent (.75%) of the Purchase Price (the
"BASKET"), then Fintube shall have no obligation under this Article IX with
respect to any such Purchaser Claims. If the total amount of all Purchaser
Claims exceeds the Basket, then Fintube's obligations under this Article IX
shall be limited to the amount by which the aggregate amount of all Purchaser
Claims exceeds seventy five hundredths of one percent (.75%) of the Purchase
Price, but such excess amount shall not exceed the Cap. Notwithstanding anything
in this Section 9.7 to the contrary, Purchaser Claims made pursuant to Sections
4.3(a), 5.9, 5.25 and 9.4 shall not be subject to the Basket.

                 (c) The total amount of Fintube's obligations with respect to
Purchaser Claims, under this Article IX shall not exceed forty percent (40%) of
the Purchase Price (the "CAP").

                 (d) The amount which an Indemnifying Party is required to pay
to, for, or on behalf of any other party pursuant to this Section 9.7 shall be
reduced (including, without limitation, retroactively): (i) by any insurance
proceeds actually recovered by or on behalf of any Indemnified Person; and (ii)
by any net tax benefit actually realized as a result of any indemnifiable loss.
If an Indemnified Person shall have incurred or shall have paid on its behalf an
indemnifiable loss, and shall subsequently receive insurance proceeds in respect
of such indemnifiable loss, or shall realize any net tax benefit as a result of
such indemnifiable loss, then the Indemnified Person shall promptly pay to the
Indemnifying Party such amount. Each Indemnified Person agrees to use reasonable
efforts (so long as such efforts would not have an adverse effect on such
Person) to obtain any such tax benefit and any such insurance proceeds.

                 (e) Purchaser agrees that Fintube, at Fintube's option and
expense, may obtain an insurance policy satisfactory to both Purchaser and
Sellers, with a coverage limit of not less than $27,800,000 and no deductible
other the Escrow Account, naming Purchaser (and any Indemnified Persons) as the
insured, to satisfy any and all Claims against Sellers under this Article IX, to
the extent such Claims have exceeded the amount of the Escrow Account. In the
event Sellers obtain


                                       58
<PAGE>


such insurance, after first exhausting the funds in the Escrow Account, the
Purchaser will look, and will cause all Indemnified Persons to look, solely to
such insurance policy for satisfaction of any and all Claims against Sellers in
excess of the amount of the Escrow Account. To the extent Sellers elect to
obtain the above described insurance, Sellers shall have no further liability to
Purchaser under this Article IX after the Closing in excess of the amount of the
Escrow Account.

         9.8 FINTUBE'S ESCROW. To satisfy any Purchaser Claim, Warranty Claim to
be paid by Fintube, any claim for any adjustment owed by Fintube for payment of
real property taxes or Brokers' Fees pursuant to Section 4.3(a) (any of such
Claims shall be an "ESCROW CLAIM") that the Purchaser has the right to recover
against Fintube hereunder, Fintube agrees that Purchaser shall transfer at
Closing, Five Million Dollars ($5,000,000) of the Purchase Price, directly to an
escrow account in the name of Fintube (the "ESCROW ACCOUNT"), at a mutually
agreed bank or other suitable financial institution in Tulsa, Oklahoma, (the
"ESCROW AGENT"). After the amount of Purchaser Claims has exceeded the Basket,
or upon the occurrence of other Escrow Claims without regard to the Basket, the
Purchaser shall be entitled to assert such Escrow Claims against the Escrow
Account, by written notice to Fintube and Escrow Agent. Such claims shall be
paid by the Escrow Agent within twenty (20) days of the date said written claims
are received by Fintube and Escrow Agent, unless Fintube objects to such claims
in writing within said twenty (20) day period. If there is a Fintube objection
to a an Escrow Claim, the claim shall be resolved by negotiation between Fintube
and the Purchaser within thirty (30) days from the date of Fintube's objection.
If not so resolved, either party may submit the Escrow Claim to arbitration
pursuant to Section 10.12. One-half of the balance of the Escrow Account, less
any unresolved Escrow Claims, will be disbursed to Fintube on the 15th day after
the completion of the audit of the calendar year 2000 financial statements of
the Business. Purchaser hereby agrees to use its reasonable best efforts to
cause the audit of the calendar year 2000 financial statements of the Business
to be completed on or before March 31, 2001. The balance of the Escrow Account,
less any unresolved Escrow Claims, will be disbursed to Fintube on or before the
15th day after the completion of the audit of the calendar year 2001 financial
statements of the Business. The funds in the Escrow Account shall be invested in
income producing securities to be selected by Fintube, and all income produced
thereby shall be distributed to Fintube on a quarterly basis. The terms of the
escrow arrangement shall be specified in the Escrow Agreement attached hereto as
EXHIBIT 9.7.

         9.9 EXCLUSIVE REMEDY. Purchaser's and Fintube's sole remedy for any
breach of any of the provisions of this Agreement shall be to exercise their
rights under Articles IX and X, subject to the procedures and limitations set
forth in Articles IX and X.

         9.10 SURVIVAL. The representations, warranties, covenants and
agreements made in this Agreement or in any certificate or instrument delivered
in connection herewith shall be in full force and effect, notwithstanding any
investigation made by or disclosure made to any Party, whether before or after
the date hereof, shall survive the execution and delivery of this Agreement, and
shall survive the Closing and continue to be applicable and binding, until the
15th day after the completion of the audit of the calendar year 2001 financial
statements of the Business, at which time said representations, warranties,
covenants and agreements shall forever terminate. The foregoing notwithstanding,
the representations, warranties, covenants and agreements made in this
Agreement, or in any certificate delivered in connection herewith, shall forever
terminate on April 15, 2002.

made in accordance with the Securities Act and applicable state securities laws.

part to an acquisition subsidiary of Purchaser or an Affiliate thereof; provided

Any Party may change its name or address for receiving notices by giving written
notice of such change to the other Parties in accordance with this Section 10.7.

         10.8 AMENDMENT. Except as allowed by Section 5.12, this Agreement may
be amended by the Parties hereto, only by a written instrument signed by all of
the Parties hereto.

         10.9 SEVERABILITY. Any term or provision of this Agreement that is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability, without
rendering invalid or unenforceable the remaining terms and provisions of


                                       61
<PAGE>


this Agreement or affecting the validity or enforceability of any of the terms
or provisions of this Agreement in any other jurisdiction. If any provision of
this Agreement is so broad as to be unenforceable, such provision shall be
interpreted to be only so broad as is enforceable.

         10.10 WAIVERS. The Parties hereto may, by mutual agreement, to the
extent legally allowed: (a) extend the time for the performance of any of the
obligations or other acts required herein; (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto; and (c) waive performance of any of the covenants or
agreements, or satisfaction of any of the conditions contained herein. Any
agreement on the part of a Party to any such extension or waiver shall be valid
only if set forth in a written instrument signed on behalf of any Party. Except
as provided in this Agreement, no action taken pursuant to this Agreement,
including any investigation by or on behalf of either Party, shall be deemed to
constitute a waiver by the Party taking such action of compliance with any
representations, warranties, covenants or agreements contained in this
Agreement. The waiver by any Party of a breach of any provision hereof shall not
operate or be construed as a waiver of any prior or subsequent breach of the
same or any other provisions hereof.

         10.11 ENFORCEMENT OF AGREEMENT. The Parties agree that irreparable
damage would occur in the event that any provision of this Agreement was not
performed in accordance with the terms hereof or was otherwise breached.
Accordingly, irrespective of the provisions of Section 10.12, the Parties hereto
agree that each Party shall be entitled to seek an injunction to prevent a
breach of this Agreement, and shall be entitled to specific performance of the
terms and provisions hereof.

         10.12   ARBITRATION.

                 (a) GOOD FAITH NEGOTIATION. Except as provided in Section
10.11, in the event that any Party asserts that there exists any disagreement,
dispute, controversy or claim arising out of or relating to this Agreement (a
"DISPUTE"), such Party shall deliver a written notice to each other Party
involved therein specifying the nature of the asserted Dispute and requesting a
meeting of the Responsible Officers of both Parties to attempt to resolve the
same. A face to face meeting of the Responsible Officers and their
representatives shall be held within twenty (20) days of delivery of the written
notice, and shall last for a minimum of three (3) hours. If no such resolution
is reached within fifteen (15) days after such face to face meeting, the Party
delivering such notice of Dispute (the "DISPUTING PERSON") may, within thirty
(30) days after such face to face meeting, commence arbitration hereunder by
delivering to the other Party a notice of arbitration (a "NOTICE OF
ARBITRATION"). Such Notice of Arbitration shall specify the matters as to which
arbitration is sought, the nature of any Dispute, the claims of each Party to
the arbitration and shall specify the amount and nature of any damages, if any,
sought to be recovered as a result of any alleged claim, and any other matters
required by the Commercial Arbitration Rules of the American Arbitration
Association as in effect from time to time to be included therein, if any.
Except for the enforcement provisions contained in Section 10.11 arbitration
shall be the sole remedy for the resolution of a Dispute.

                 (b) ARBITRATION RULES; LOCATION. The arbitration shall be
conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association, except as those rules conflict with the provisions of
this Section 10.12, in which event the provisions of this Section 10.12


                                       62
<PAGE>


shall control. Any arbitration hereunder shall be conducted at Tulsa, Oklahoma,
or at such other location as shall be agreed to by the Parties hereto in
writing.

                 (c) ONE NEUTRAL ARBITRATOR. The Dispute shall be resolved by
one neutral arbitrator who shall: (i) have general knowledge and experience in
the manufacturing industry and in the matters addressed in the Dispute; (ii)
have no affiliation with any Party; and (iii) be selected by the American
Arbitration Association office in Dallas, Texas ("AAA"); provided, that with
respect to the Dispute submitted to arbitration pursuant to a Notice of
Arbitration, each Party shall have the absolute right to reject one (but no more
than one) arbitrator selected by the AAA within fifteen (15) days of being
notified by the AAA as to the identity of the arbitrator, in which event such
person shall be de-selected and the AAA shall select another neutral arbitrator.

                 (d) DECISION OR AWARD. Any decision or award of the arbitrator
shall be final and binding upon the parties to the arbitration proceeding. The
Parties agree that the arbitration award may be enforced against the Parties to
the arbitration proceeding or their assets wherever they may be found, and that
a judgment upon the arbitration award may be entered in any court having
jurisdiction thereof.

                 (e) COSTS AND EXPENSES. All out of pocket costs and expenses
incurred by any Party in connection with an arbitration resolution of any
disagreement, dispute, controversy or claim pursuant to this Section 10.12,
including but not limited to reasonable attorney's fees and disbursements, shall
be borne by the Party incurring the same; provided, however, that the arbitrator
shall have the discretion to declare any Party to the arbitration proceeding as
the "prevailing party" with respect to one or more of the issues that were the
subject of the arbitration, and to require the other Party to the arbitration to
reimburse such "prevailing party" for the some or all of its costs and expenses
incurred in connection with such proceeding.

         10.13 PERFORMANCE BY SELLERS. Fintube agrees to cause each of the other
Sellers, not included as parties to this Agreement, to perform any obligations
of such Sellers described in this Agreement.

         9. The following is added as a new paragraph after Section 2.6(i):

                    "Notwithstanding the foregoing, Fintube will assume all of

         12. Purchaser affirms to Sellers that the Purchaser declines to assume
             the IRB Debt. Accordingly, the IRB Debt shall be paid and
             discharged by the Sellers at Closing, as set forth in Section
             3.2(b)(i).

         13. The third sentence of Section 5.10 of the Asset Purchase Agreement
             is hereby amended and replaced with the following:

                      "In addition, Fintube shall be responsible for any
                      United States, Canadian or Mexican federal, state or
                      provincial income taxes of the Sellers, resulting
                      from the transaction contemplated in this Agreement;
                      and Fintube shall cause the Designated Recipients to
                      be responsible for any United States, Canadian or
                      Mexican federal, state or provincial income taxes of
                      the Designated Recipients resulting from the
                      transaction contemplated in this Agreement."

         14. Purchaser confirms to Sellers that all Environmental
             Deficiencies identified in Section 5.25 of the Asset Purchase
             Agreement have been satisfied, corrected or resolved to the
             satisfaction of Purchaser. The foregoing notwithstanding,
             nothing contained in this Agreement will modify or amend the
             Sellers' representations and warranties contained in Section
             4.1(q) of the Asset Purchase Agreement.

         15. A new SECTION 5.27, "COVENANTS REGARDING AyB", shall be added
             to the Asset Purchase Agreement, and shall state as follows:

             "5.27    COVENANTS REGARDING AyB. Fintube covenants and agrees
                      that, at its own cost and expense, it will pay,
                      perform or otherwise discharge, as appropriate, those
                      known AyB liabilities listed below in clauses (i)
                      through (vii) inclusive (collectively the "MEXICAN
                      RETAINED LIABILITIES"), to be accomplished by the
                      respective target dates indicated below:

                      (i) Fintube will transfer the stock certificates
                      described in Section 3.2(a)(viii) of this Agreement
                      and not available at the Closing to AyB Mexicana,

<PAGE>

                       within one hundred and twenty (120) days of the
                       Closing and, to the extent necessary, will commence
                       and complete any Mexican judicial proceeding within
                       said period to effect said transfer;

                       (ii) Fintube will effect a recapitalization or other
                       mutually acceptable corporate reorganization of AyB
                       by February 15, 2000 that will: (a) cancel the Gomez
                       Shares; and (b) terminate any and all rights Roberto
                       Gomez Portugal may have in any of the equity of AyB,
                       except for his right to receive a pro rata share of
                       the purchase price of AyB;

                       (iii) Fintube will negotiate with, and make any
                       required payment to, Banco Internacional, S.A. (the
                       "BANK") to secure the complete and final release of
                       the three (3) liens (collectively the "MEXICAN
                       LIENS") against AyB or its assets in favor of the
                       Bank and securing credits in the respective amounts
                       of P$100,939 (recorded March 16, 1984), P$23,631
                       (recorded November 27, 1984) and P$15,542 (recorded
                       February 4, 1986). If through negotiation Fintube
                       does not obtain the complete and final release of the
                       Mexican Liens by February 15, 2000, Fintube will
                       initiate and prosecute a judicial proceeding on
                       behalf of AyB against the Bank to obtain the complete
                       and final release of the Mexican Liens by a date no
                       later than December 31, 2000;

                       (iv) Fintube will: (a) cooperate with Lone Star and
                       AyB, and will promptly review, in good faith, AyB's
                       records to determine whether AyB owes any unpaid
                       import duties or other payments in connection with
                       the Pitex program, with respect to any period
                       occurring prior to the Closing Date; and (b) pay any
                       duties or other payments due in connection therewith,
                       by January 31, 2000;


                       (v) Fintube will: (a) cooperate with Lone Star and
                       AyB, and will promptly review, in good faith, AyB's
                       records to determine whether AyB owes any unpaid
                       social security taxes or related payments due with


                                      -7-
<PAGE>


                           respect to any period occurring prior to the Closing
                           Date; and (b) pay any such social security taxes or
                           related payments due in connection therewith, by
                           January 31, 2000;

                           (vi) Fintube will use its best efforts on behalf of
                           AyB to successfully litigate to a conclusion by June
                           30, 2000, all environmental fines, penalties and
                           other payments due the Mexican Federal Environmental
                           Protection Office ("PROFEPA") to eliminate AyB being
                           categorized as a habitual offender by PROFEPA. If
                           Fintube has not succeeded in its litigation with
                           PROFEPA by June 30, 2000, Fintube will on such date
                           pay all fines, penalties and other payments due
                           PROFEPA; and

                           (vii) Fintube will respond in good faith on behalf of
                           AyB to the Hacienda tax audit of AyB for 1995, and
                           will pay any additional taxes, interest or penalties
                           required to be paid as a result of such audit.

             To the extent Fintube does not pay, perform or discharge any of the
             Mexican Retained Liabilities, Purchaser may assert any such Mexican
             Retained Liabilities against the Escrow Account, without regard to
             the Basket."

         16. A new SECTION 7.3(s), "MEXICAN OPINION", shall be added to the
             Asset Purchase Agreement, and shall state as follows:

                 "(s) MEXICAN OPINION.  Lone Star and Purchaser shall have
                 received the legal opinion(s) of Martinez, Rodriquez y
                 Asociados, S.C. and Rivadeneyra  y Trevio, S.C. in  form
                 and substance reasonably satisfactory to Lone Star and
                 Purchaser."

         17. Section 9.1 of the Asset Purchase Agreement is hereby amended and
             replaced with the following:


             "9.1   INDEMNIFICATION. After the Closing, both Fintube and
                    Purchaser (each an "INDEMNIFYING PARTY") hereby agree to
                    indemnify, defend and hold harmless the other Party, and its
                    directors, officers, employees and controlled and
                    controlling persons (hereinafter collectively "RELATED
                    PERSONS"), from and against all Claims asserted against,
                    resulting to, imposed upon or

                    incurred by such Party or such Party's Related Persons
                    (collectively an "INDEMNIFIED PERSON"), subject to all of
                    the provisions and limitations contained in this Article IX,
                    to the extent resulting from: (a) the inaccuracy or breach
                    of any representation or warranty of the Indemnifying Party
                    contained in or made pursuant to this Agreement; (b) the
                    breach of any covenant of the Indemnifying Party contained
                    in or made pursuant to this Agreement; or (c) in the
                    circumstance where Fintube is the Indemnifying Party, the
                    AyB Indemnified Liabilities (as defined below); provided,
                    however, the AyB Indemnified Liabilities shall not be
                    subject to the limitations of Section 9.7(b), but will be
                    subject to the other provisions and limitations of Article
                    IX. For purposes of determining whether an Indemnified
                    Person is entitled to indemnification under this Article IX
                    due to the breach of an Indemnifying Party's representation
                    or warranty, the materiality qualification in such
                    representation or warranty shall be disregarded and such
                    representation or warranty shall be read for purposes of
                    this Article IX as though such qualification was not
                    included therein (it being agreed by the Parties that the
                    Basket described in Section 9.7(b) hereof was intended to
                    supplant such materiality qualification). As used in this
                    Article IX, the term "CLAIM" shall include, (x) all debts,
                    liabilities and obligations, (y) all losses, damages, costs
                    and expenses, including pre- and post-judgment interest,
                    penalties, court costs and attorneys' fees and expenses, and
                    (z) all demands, claims, actions, costs of investigation
                    causes of action, proceedings, arbitrations, judgments,
                    settlements and assessments.

             "AyB INDEMNIFIED LIABILITIES" shall consist of any and all Claims
             related to or resulting from the following:

                    (a) The operation, management or conduct of the Business by
                        AyB, or the ownership or use of the assets of AyB, prior
                        to the Closing Date and any Retained Liabilities
                        applicable to AyB; provided, however, AyB Indemnified
                        Liabilities shall not include : (i) any Claims to the
                        extent of reserves established in Sellers Financial

                        expenses and obligations of AyB incurred in the ordinary

                        including ongoing contractual obligations; and (vi)
                        liabilities of AyB, the factual basis of which is
                        disclosed in the Schedules to Article IV of this
                        Agreement; or

                    (b) Subject to the provisions of Section 9.4 hereof, any
                        defective products manufactured, designed, distributed
                        or sold by AyB on or prior to the Closing Date,
                        including any damages, costs and losses related to
                        product recalls; provided, however, AyB Indemnified
                        Liabilities shall not include: (i) any Claims to the
                        extent of reserves established in Sellers Financial
                        Statements with respect to AyB, or in the Subsidiary
                        Financial Statements for AyB; and (ii) liabilities of
                        AyB, the factual basis of which is disclosed in the
                        Schedules to Article IV of this Agreement."

         18. The last sentence of Section 9.7(b) of the Asset Purchase Agreement
             is hereby amended and replaced with the following:

                    "Notwithstanding anything in this Section 9.7 to the
                    contrary, Purchaser Claims made pursuant to Sections 4.3(a),

         19. Section 9.7(c) of the Asset Purchase Agreement is hereby amended
             and replaced with the following:

                    "(c) The total amount of Fintube's obligations with respect

             is hereby amended and replaced with the following:

                    bank or other suitable financial institution in Tulsa,
                    Oklahoma (the "ESCROW AGENT")."

         21.      The sixth sentence of Section 9.8 of the Asset Purchase
                  Agreement is hereby amended and replaced with the following
                  three (3) sentences:

                    from the Escrow Account when the Mexican Liens are

                    the Escrow Account will be disbursed to Fintube from the
                    Escrow Account when the other Mexican Retained Liabilities,
                    described in clauses (i) through (vi) inclusive of Section

                    distributed to the Designated Recipients by the Escrow Agent
                    on a quarterly or other basis designated by Fintube. All
                    income produced by the Escrow Account shall be the sole and
                    exclusive property of Fintube, and shall not be subject to

                   LONE STAR TECHNOLOGIES, INC. COMPLETES THE
                    PURCHASE OF FINTUBE LIMITED PARTNERSHIP


Dallas, TX, January 3, 2000 ..... Lone Star Technologies, Inc. (Lone Star),
NYSE:LSS, announced that it has completed the purchase of Fintube Limited
Partnership's assets, a privately held, Tulsa-based manufacturer of finned
tubes used in a variety of heat recovery applications.

The purchase price was approximately $86 million which included the issuance
of 760,000 shares of Lone Star common stock valued at $20 million.  The
assets were purchased by Fintube Technologies, Inc.,  (Fintube) a new
wholly-owned subsidiary of Lone Star.  Fintube also executed a new $59
million credit agreement with a bank group.  The initial funding under the
credit agreement was approximately $46 million with the balance available for
working capital, and new capital investments subject to borrowing base
limitations.  The balance of the purchase price was provided by Lone Star
from additional borrowings.

Fintube is the leader in the design and production of finned tubes which are
used in a variety of heat recovery applications.  For the past five years,
Fintube has invested in additional capacity and research and development of
new products to better serve the growing world demand for heat recovery
systems.  Its share of domestic Heat Recovery Steam Generation (HRSG)
manufacturing capacity for finned tubes is approximately 70% and its share of
world HRSG capacity, including licensees of its manufacturing technology in
Japan, Korea, Italy and India, is estimated to be 50%.  Its customers include
suppliers of heat recovery boiler sections used in gas-fired, combined cycle
power generating plants.  Fintube anticipates this market will grow rapidly
in the near future.  Fintube also designs and manufactures other products,
such as boiler economizers, boiler tubing and enhanced-surface tubing.  Some
of these products will be marketed through the same distribution channels as
Lone Star's specialty tubing products.

Fintube's revenues and EBITDA for the 1998 calendar year were $61.2 million
and $9.1 million, respectively, and for the first nine months of 1999 were
$60.7 million and $14.8 million, respectively. The acquisition is expected to
be accretive to Lone Star's earnings per share.

Rhys J. Best, Chairman, President and Chief Executive Officer of Lone Star,
stated, "Fintube is a remarkable success story.  We are pleased to combine
its market leadership position in the design and production of finned tubes
for the power generation industry and other applications with Lone Star's
widely respected tubular expertise and leadership in oilfield and specialty
tubing products.  Fintube will operate with current management and the
employment is anticipated to continue at present levels."

Lone Star Technologies, Inc. is a holding company whose principal operating
subsidiaries are Lone Star Steel Company, which manufactures and markets
oilfield casing, tubing, and line pipe, specialty tubing products, flat
rolled steel and other tubular products and services, and Fintube
Technologies, Inc.
