<PAGE>
                            ASSET PURCHASE AGREEMENT


                     THIS AGREEMENT (the "Agreement") is made on November 6,
2001, between LANDRETH METAL FORMING, INC., a Texas corporation (the "Seller"),
INDUSTRIAL HOLDINGS, INC., a Texas corporation ("IHI") (the Seller and IHI
sometimes collectively referred to herein as the "Seller Parties"), and LANDRETH
FASTENER CORPORATION, a Texas corporation (the "Buyer").

                                   BACKGROUND


A.         IHI is the owner of all the issued and outstanding capital stock of
           the Seller.


B.         The Seller manufactures solid, semi-tubular & shoulder rivets,
           externally threaded-fasteners and other cold-headed special parts in
           diameters from 3/16" to 1/2" (the "Business"):

C.         The Seller is the sole remaining entity in IHI's Engineered Products
           Group division (the "EPG Division"). Rex Machinery Movers, Inc. d/b/a
           Ideal Products ("Ideal Products"), Philform, Inc. ("Philform"), the
           limited partnership OF Acquisition, L.P. d/b/a Orbitform
           ("Orbitform") and American Rivet Company, Inc. ("American Rivet"),
           which recently sold substantially all of their assets, were formerly
           part of the EPG Division (the Seller, Ideal Products, Philform,
           Orbitform and American Rivet, collectively, the "EPG Division
           Members"). As part of the strategic disposition of the assets of the
           EPG Division from IHI's core business, Ideal Products, Philform,
           Orbitform and American Rivet have sold substantially all of their
           assets to purchasers other than the Buyer. However, the acquirers
           thereof, as well as the Buyer, are interested in (i) maintaining the
           customer and manufactured part-base that the EPG Division Members
           have historically enjoyed, without the prospect of the solicitation
           of those customers by each other, and (ii) continuing to utilize
           certain computer hardware, software and services that they are
           currently provided or have access to but that are not included among
           the Purchased Assets. Therefore, as a condition precedent to the
           Closing (as that term is defined below), the Buyer shall succeed to
           Seller's rights and assume Seller's obligations under (i) a customer
           and manufactured part-based Nonsolicitation Agreement attached as
           EXHIBIT A (the "Nonsolicitation Agreement") and (ii) a transitional
           services agreement attached as EXHIBIT B (the "Transitional Services
           Agreement").

D.         IHI acquired all of the capital stock of the Seller from, among
           others, Thomas C. Landreth ("Landreth"), the President of the Buyer,
           in 1992. Since that time, Landreth has been involved in the operation
           of the Business in a management capacity as either the President of
           the Seller or as Chief Technology Officer of the EPG Division. The
           parties therefore hereby acknowledge that Landreth is in many cases
           as knowledgeable as the Seller Parties regarding the Business, the
           Purchased Assets (as defined in Section 1 below), and the financial
           statements of the Seller.

E.         Buyer desires to purchase, and Seller desires to sell to Buyer, the
           Purchased Assets on the terms and subject to the conditions of this
           Agreement.

                                   AGREEMENTS


           NOW, THEREFORE, consistent with the Background and in consideration
of the terms and conditions set forth in this Agreement, each of the Seller
Parties and Buyer agree as follows:


1. ASSETS PURCHASED. At the Closing, Seller shall sell, assign, convey,
transfer, set over, and deliver to Buyer all of the assets, rights, and
interests of every conceivable kind or character whatsoever, whether tangible or
intangible, that on the Closing Date (as that term is defined below) are owned
by Seller or in which Seller has an interest of any kind, that are used in the
Business, except (a) for the Excluded Assets (as that term is defined in Section
2 below); and (b) that only Equipment (as that term is defined in Section 1.1
below) physically located on the Seller's premises shall be conveyed to the
Buyer (the assets being so purchased, the "Purchased Assets"). Other than with
respect to warranties of title, Seller shall transfer the Purchased Assets to
Buyer, and Buyer shall accept the Purchased Assets from Seller on an "AS IS,
WHERE IS" basis, with no representations or warranties of any kind or nature,
including without limitation, as to the physical or operational condition of the
Purchased Assets.


           The Purchased Assets include, without limitation:

           1.1 EQUIPMENT. All machinery, equipment, tools, fixtures,
workstations, computers, office equipment, manufacturing and engineering
drawings, and tangible personal property owned by Seller, and to the extent not
otherwise constituting equipment as defined above, all other items of tangible
personal property, all as physically located on the Premises (including, without
limitation, the items listed on SCHEDULE 1.1) (the "Equipment").

           1.2 INVENTORY. All raw materials inventory, work-in-process
inventory, and finished goods inventory owned by Seller (including, without
limitation, the items listed on SCHEDULE 1.2, except to the extent of changes
thereto in the Ordinary Course of Business (as that term is defined below) prior
to the Closing Date) (the "Inventory");

           1.3 RECEIVABLES. All accounts, chattel paper, documents, and
instruments (all as defined in the Uniform Commercial Code, as adopted in the
State of Texas (the "UCC")), and any security Seller holds for the payment
thereof (including, without limitation, the items described on SCHEDULE 1.3),
except to the extent of changes thereto in the Ordinary Course of Business prior
to the Closing Date) (the "Receivables"), and all of Seller's general

                     Seller Parties shall cause to be prepared and delivered to
                     the Buyer a Statement of Net Working Capital (as that term
                     is defined in subparagraph (c) below) of the Seller as of
                     the Closing Date (such statement, the "Closing Date
                     Statement"). The Closing Date Statement shall be prepared
                     in accordance with generally accepted accounting
                     principles, consistently applied ("GAAP") and shall set
                     forth the information required to calculate Net Working
                     Capital. The Buyer shall give the Seller Parties and their
                     representatives reasonable access to the books, records and
                     personnel of the Business for the purpose of preparing and

                     period of 30 calendar days after the delivery to it of the
                     Closing Date Statement, and during such time the Buyer
                     shall have access to all workpapers and other relevant
                     documents, to review the foregoing and to deliver in

ASSET PURCHASE AGREEMENT                                         EXECUTION COPY
<PAGE>
                     objections to the Closing Date Statement that the Buyer may
                     have. If Buyer does not deliver in writing any objections
                     to the Seller Parties within the 30-day period, the Closing
                     Date Statement shall be deemed to be accepted and approved
                     by the Buyer. If Buyer delivers within the 30-day period
                     written objections to the Seller Parties, then the Buyer
                     and Seller Parties shall attempt to resolve the matter or
                     matters in dispute. The Buyer shall quantify its objections
                     to the extent reasonably practicable in all written
                     objections delivered to the Seller Parties with respect to
                     the Closing Date Statement.

           (b)       If such disputes cannot be resolved by the Buyer and Seller
                     Parties within 20 calendar days after the delivery of the
                     objections to the Closing Date Statement, then the specific
                     matters in dispute shall be submitted to the Independent
                     Accountants, which firm shall render its opinion as to such
                     matters. Based on that opinion, the Independent Accountants
                     shall then send to the Buyer and to each of the Seller
                     Parties a written determination of the matters in dispute
                     and a written determination of the Purchase Price as
                     adjusted based upon such opinion, whereupon the confirmed
                     or revised Closing Date Statement shall be final and
                     binding upon the Buyer and each of the Seller Parties,
                     absent manifest error. All costs, fees and expenses charged
                     or incurred by the Independent Accountants, if any, shall
                     be borne equally by (i) the Seller Parties, jointly, and
                     (ii) the Buyer.

           (c)       For purposes hereof, "Net Working Capital" means, as of the
                     date of the Closing Date Statement and based thereon, an
                     amount equal to Seller's Receivables and Inventory minus
                     Seller's trade and other current accrued payables
                     (excluding accrued vacations) that the Buyer will assume at
                     the Closing under Section 3.1(a) and (b). The Inventory
                     shall be valued at the Seller's standard cost without
                     regard to any reserve for obsolescence or other
                     adjustments. The Purchase Price shall be increased by the
                     amount by which the Net Working Capital contained in the
                     Closing Date Statement is greater than $694,000, and shall
                     be decreased by the amount by which the Net Working Capital
                     contained in the Closing Date Statement is less than
                     $694,000 (whether an increase to or decrease from the
                     Purchase Price, the "Purchase Price Adjustment"). The
                     Purchase Price Adjustment shall be paid by the Seller
                     Parties to Buyer, or Buyer to the Seller Parties, as the
                     case may be, within 5 days of the determination of the
                     Purchase Price Adjustment. If Seller Parties are obligated
                     to pay the Purchase Price Adjustment to Buyer and if
                     payment is not made within 5 days of the determination of
                     the Purchase Price Adjustment, Buyer shall have the option
                     (but not the obligation) to set off the Purchase Price
                     Adjustment against obligations under the Note.

                     become binding upon or an obligation, liability or
                     responsibility of Buyer in any way, financial or otherwise.
                     The Seller has not engaged in any action or omission which
                     may result in Buyer being a party to, or bound by, any
                     Employee Plan. No Employee Plan provides for payment of
                     termination, change of control or retiree benefits in any
                     manner such that Buyer would become liable to provide such
                     benefits.

           (b)       With respect to any Employee Plan that is subject to the
                     continuation requirements of Sections 601-608 of ERISA and
                     Section 4980B of the Code, or the continuation requirements
                     of any applicable state or local law, the Seller's
                     sponsoring, maintaining or contributing to such Employee
                     Plans has complied with all such applicable laws and
                     regulatory requirements with respect to the Seller's
                     current or former employees.

           (c)       No Employee Plan is either (i) a "multiemployer plan" (as
                     defined in Section 3(37) of ERISA) or (ii) a defined
                     benefit pension plan subject to Title IV of ERISA.

           (d)       During the five years preceding the Closing Date, (i) no
                     under-funded pension plan subject to Section 412 of the
                     Code has been transferred out of the Seller and (ii) Seller
                     has not participated in or contributed to, nor had an
                     obligation to contribute to, any multiemployer plan (as
                     defined in ERISA Section 3(37)) and Seller does not have
                     any withdrawal liability with respect to any multiemployer
                     plan.

           9.10 CONTRACTS. Except for (i) the contracts and commitments listed
on SCHEDULE 9.10 ("Contracts and Commitments"), (ii) contracts and commitments
specifying payment by the Seller or to the Seller of $25,000 or less over the
term of such contract or commitment; or (iii) the Outstanding Customer Purchase
Orders, the Seller is not a party to nor bound by any agreement or commitment
that materially affects the Business, the Purchased Assets, or the Assumed
Liabilities. All Contracts and Commitments are valid and binding obligations of
the Seller in accordance with their respective terms. No material default or
alleged material default exists on the part of the Seller or, to either Seller
Party's knowledge, on the part of any other party, under any of the Contracts
and Commitments. True and complete copies of all Contracts and Commitments have
been delivered to Buyer.

           9.11      TITLE TO PURCHASED ASSETS; LIENS.

           (a)       Seller is the owner of and has good title to all of the
                     Purchased Assets, free and clear of all liens, claims,
                     demands, charges, options, equity interests, leases,
                     pledges and security interests ("Liens"), except (i) as
                     described on SCHEDULE 9.11 and (ii) except for liens for
                     personal property taxes that are not yet due and payable.
                     When Buyer pays to the applicable creditor, at Seller's
                     direction, the amounts identified in the letters that will
                     be delivered to Buyer at the Closing pursuant to Section
                     8.2(a)(iii), Seller shall obtain a release of all Liens
                     except those described in Items No. 12 and 13 of SCHEDULE
                     9.11 .

           (b)       SCHEDULE 9.11 lists or describes all property used in the
                     conduct of the Business that is owned by or an interest in
                     which is claimed by any other person (whether a customer,
                     supplier, or other person) and for which Seller is
                     responsible, together with copies of all related
                     agreements.

           9.12      TAXES.

           (a)       "Tax" or "Taxes" shall mean any and all of the Seller's
                     foreign, federal, state, county, local, and other taxes
                     (including, without limitation, income taxes; premium
                     taxes; single-business taxes; excise taxes; sales taxes;
                     use taxes; value-added taxes; gross receipts taxes;
                     franchise taxes; ad valorem taxes; real estate taxes;
                     severance taxes; capital levy taxes; transfer taxes; stamp
                     taxes; employment, unemployment, and payroll-related taxes;
                     withholding taxes; and governmental charges and
                     assessments; and all transfer taxes and like charges
                     payable on and in connection with Seller's conveyance and
                     transfer of the Purchased Assets to Buyer), together with
                     interest, additions to tax, and penalties with respect
                     thereto.

           (b)       Seller has filed on a timely basis all Tax returns it is
                     required to file under foreign, federal, state, or local
                     law, and has paid or established an adequate reserve with
                     respect to all Taxes for the periods covered by such
                     returns. No agreements have been made by or on behalf of
                     Seller for any waiver or for the extension of any statute
                     of limitations governing the time of assessment or
                     collection of any Taxes. Seller and its officers have not
                     received any notice of any pending or threatened audit by
                     the IRS or any state or local agency related to its Tax
                     returns or Tax liability for any period, and a claim for
                     assessment or collection of Taxes has not been asserted
                     against Seller. There are no foreign, federal, state, or
                     local Tax liens outstanding against any of Seller's assets
                     (including, without limitation, the Purchased Assets) or
                     the Business.

           (c)       The Seller's sale of the Purchased Assets to the Buyer
                     pursuant to this Agreement will not result in the
                     imposition of, or liability of the Buyer for, any Transfer
                     Taxes.

           9.13 LITIGATION. There are no claims, disputes, actions, suits,
proceedings, or investigations pending or, to Seller's knowledge, threatened,
against or affecting the Seller, the Business, or the Purchased Assets.

           9.14 PRODUCT LIABILITY. There are no known defects or deficiencies
existing in any of the products manufactured or sold by the Seller, or in any
finished Inventory of the Seller, that could give rise to any liabilities or
claims for product liability.

           9.15 BROKERS. Seller has not engaged, and is not responsible for any
payment to, any finder, broker, or consultant in connection with the
transactions contemplated by this Agreement, except as set forth on SCHEDULE
9.15.

           9.16 INTELLECTUAL PROPERTY. SCHEDULE 9.16 lists all patents,
processes, trademarks, trade names, copyrights, service marks, logos, trade
secrets and all applications and registrations therefor that are used in the
Business, and licenses thereof under which the Seller has any right to the use
or benefit of, or other rights with respect to, any of the foregoing
("Intellectual Property"). Except as set forth in SCHEDULE 9.16, the Seller is
the sole and exclusive owner of the Intellectual Property, free and clear of all
Liens. To the Seller Parties' knowledge, none of the Seller's Intellectual
Property infringes on any other person's intellectual property, and, to the
Seller Parties' knowledge, no activity of any other person infringes on any of
the Intellectual Property. To the Seller Parties' knowledge, the Seller has been
and is now conducting the Business in a manner that has not been

                                       15

Seller does not require a license or other proprietary right to so operate the
Business.

knowledge of such Seller Party's executive officers, except in the case of the
Seller, it means the actual knowledge of its executive officers other than
Landreth.

           10.5 BUYER'S KNOWLEDGE. Landreth has no actual knowledge (and the
knowledge of other persons, including individuals and corporations or other
entities, shall not be imputed to Landreth) of any facts or circumstances that
would indicate that any of the representations or warranties of Sellers Parties
are inaccurate or untrue in any material respects as of the date made. For
purposes of this Agreement, Landreth's knowledge of a fact or circumstance shall
in all cases be attributed to the Buyer.


11.        POST-CLOSING COVENANTS.

           11.1 POST-CLOSING RECEIPTS. From and after the Closing Date, Seller
Parties will promptly notify and transfer to Buyer any payments or other
receipts they receive with respect to any of the Purchased Assets. Pending any
such transfer, Seller Parties will segregate any such payments from their other
assets and will clearly mark or designate them as the property of Buyer.

           11.2 SELLER NAMES. Seller agrees that it will not use the Names
either directly or indirectly, alone or in combination with one or more other
words, in, or in connection with, any business, activities, or operations that
Seller directly or indirectly carries on or conducts.

           11.4 BOOKS AND RECORDS. Insofar as the Seller determines that any
books and records may be needed or useful in connection with federal, state or
local regulatory or tax matters, resolution of third-party disputes or contract
compliance issues, or other bona fide business purposes, for a period of seven
years after the Closing Date, Buyer will use its best efforts to preserve and
make available to the Seller, at the location of such books and records in the
Buyer's organization, access to and the right to copy such of the books and
records as such Buyer may then have in its possession or to which it may have
access upon written request of the Seller during normal business hours. The
Buyer agrees to make such of its employees and of the books and records as the
Seller may reasonably request, available at the Buyer's cost to assist in the
preparation of financial reports and tax returns for the Seller's fiscal year
ending in 2001.

           11.5 WAIVER. The Buyer hereby waives, releases, relinquishes and
acquits each of IHI, T-3 Energy Services, Inc., First Reserve Fund VIII, L.P.,

from and against all claims, counterclaims, demands, suits, rights, actions and
causes of action of any nature whatsoever, as a result of or in connection with
the sale by IHI or the EPG Division Members (other than Seller) of the assets or
capital stock of such EPG Division Members to persons other than the Buyer.

respect thereto for a period of one year beginning on the Closing Date. The
parties' covenants and agreements contained herein to be performed or observed
at or prior to the Closing shall expire at the Closing, along with all rights

           12.2      INDEMNIFICATION BY THE SELLER PARTIES.

           (a)       Subject to Section 12.3(b) below, the Seller Parties,

                     harmless Buyer and its directors, officers, shareholders,
                     successors, and assigns (the "Buyer Indemnitees") from and

                     penalties, damages (including in all cases consequential
                     and punitive damages) and expenses (including reasonable
                     legal fees) (collectively, "Damages") in connection with or
                     resulting from:

                     (i)       All debts, liabilities, and obligations of Seller
                               Parties, whether accrued, absolute, contingent,
                               known, unknown, or otherwise, but excluding any
                               Assumed Liabilities.

                     (ii)      Any inaccuracy in any representation or breach of
                               any warranty of Seller Parties contained in this
                               Agreement or any Related Agreement.

                     (iii)     Any failure by Seller Parties to perform or
                               observe in full, or to have performed or observed
                               in full, any post-Closing covenant, agreement, or
                               condition to be performed or observed by the
                               Seller Parties under this Agreement or any
                               Related Agreement.

           12.3 INDEMNIFICATION BY THE BUYER. Subject to Section 12.2(a)(ii)
above, the Buyer shall indemnify and hold harmless the Seller Parties and their
directors, officers, shareholder, agents, successors and assigns (the "Seller
Indemnitees") from and against any Damages as they are incurred or suffered by
any of them and caused by or arising out of:

           (a)       The Buyer's breach of or default in the performance of any
                     covenant or agreement in this Agreement or in any Related
                     Agreement; and

           (b)       The Buyer's breach of any representation or warranty in
                     this Agreement.

           12.4      PROCEDURE FOR INDEMNIFICATION; THIRD-PARTY CLAIMS.

           (a)       Any party claiming indemnification under this Section 12 is
                     referred to in this Agreement as an "Indemnified Person"
                     and any party against whom such claims are

                                       18
ASSET PURCHASE AGREEMENT                                         EXECUTION COPY
<PAGE>
                     asserted under this Section 12 is referred to in this
                     Agreement as an "Indemnifying Person."

           (b)       Within 15 days after receipt of notice of commencement of
                     any action by any third party evidenced by service of
                     process or other legal pleading, or with reasonable
                     promptness after the assertion in writing of any claim by a
                     third party, the Indemnified Person shall give the
                     Indemnifying Person written notice thereof, together with a
                     copy of such claim, process or other legal pleading. The
                     failure to so notify the Indemnifying Person within the
                     above time frame will not relieve the Indemnifying Person
                     of any liability it may have to the Indemnified Person,
                     except to the extent the Indemnifying Person demonstrates
                     that the defense of such action is unduly prejudiced by the
                     Indemnified Person's failure to give such notice, or except
                     if such notice is not delivered before the Expiration Date.
                     The Indemnifying Person shall have the right to undertake
                     and control the defense, settlement, compromise or other
                     disposition thereof at its own expense and through a legal
                     representative of its own choosing. The Indemnified Person
                     and its counsel shall have the right to be present at the
                     negotiation, defense and settlement of such action or
                     claim, and any settlement or compromise of any such action
                     or claim shall be subject to the approval of the

                     judgment by default in favor of the person asserting such
                     claim, has not notified the Indemnified Person of its
                     election to defend against such claim, the Indemnified
                     Person shall have the right to undertake the defense,
                     compromise or settlement of such claim through counsel of

                     or claim shall be subject to the approval of the
                     Indemnifying Party, which approval shall not be

indemnification is sought.

           12.6      LIMITATIONS ON LIABILITY.

           (a)       No claim for indemnification shall be made hereunder unless

           16.7      ARBITRATION.

           (a)       Any dispute, controversy, or claim arising out of or

                     termination, or invalidity of this Agreement, whether

                     request of any party be resolved in binding arbitration.
                     Any arbitration shall proceed in accordance with Title 9 of
                     the United States Code, as it may be amended or recodified
                     from time to time ("Title 9"), and the current Commercial
                     Arbitration Rules (the "Arbitration Rules") of the American

                     under this Section. The institution and maintenance of any
                     such action or proceeding shall not constitute a waiver of
                     the right of any party (including the party taking the
                     action or instituting the proceeding) to submit a dispute,
                     controversy, or claim to arbitration under this Section.

<PAGE>

           (c)       Any award, order, or judgment made pursuant to arbitration
                     shall be deemed final and may be entered in any court
                     having jurisdiction over the enforcement of the award,
                     order, or judgment. Each party agrees to submit to the
                     jurisdiction of any court for purposes of the enforcement
                     of the award, order, or judgment.

           (d)       The arbitration shall be held before one neutral,
                     disinterested arbitrator knowledgeable in the general
                     subject matter of the dispute, controversy, or claim and
                     selected by AAA in accordance with the Arbitration Rules,
                     except that any arbitration in which the disputed,
                     controverted, or claimed amount (as reflected on the demand
                     for arbitration, as the same may be amended) exceeds
                     $1,000,000.00 shall be held before three arbitrators, one
                     arbitrator being selected by Buyer, one by the Seller
                     Parties, and the third by the other two from a panel of
                     persons identified by AAA who are knowledgeable in the
                     general subject matter of the dispute, controversy, or
                     claim.

           (e)       The arbitration shall be held at the office of AAA located
                     in Harris County, Texas (as the same may be from time to
                     time relocated), or at another place the parties agree on.

           (f)       In any arbitration proceeding under this Section 16.7,
                     subject to the award of the arbitrator(s), each party shall
                     pay all its own expenses, an equal share of the fees and
                     expenses of the arbitrator, and, if applicable, the fees
                     and expenses of its own appointed arbitrator. The
                     arbitrator(s) shall have the power to award recovery of
                     costs and fees (including reasonable attorney fees,
                     administrative and AAA fees, and arbitrators' fees) among
                     the parties as the arbitrators determine to be equitable
                     under the circumstances.

           (g)       The interpretation and construction of this Section 16.7,
                     including, but not limited to, its validity and
                     enforceability, shall be governed by Title 9 of the U.S.
                     Code, notwithstanding the choice of law set forth in
                     Section 16.4 of this Agreement.

           16.8 PUBLIC ANNOUNCEMENTS. The parties agree to advise and confer
with each other prior to the issuance of any public reports, statements or press
releases pertaining to this Agreement and the transactions contemplated hereby.
Each party will use its best efforts to maintain in strict confidence the
existence and terms of this Agreement and the transactions contemplated hereby.
Unless otherwise required by law or as set forth above, no party shall make any
public announcement or disclosure concerning this Agreement, except as mutually
agreed. The financial terms of the Agreement are to be kept confidential, except
to the extent that the disclosure is required under law. Nothing in the
foregoing is intended to prevent IHI from making any filings required with the
Securities and Exchange Commission.

           16.9 CERTIFICATE OF NO TAX DUE. Seller ordered on November 2, 2001, a
Certificate of No Tax Due (under Section 111.020 of the Texas Tax Code) from the
Comptroller of Public Accounts of the State of Texas with respect to each Tax
under Title 2 of the Texas Tax Code with respect to which Seller is or has been
liable or filed Tax returns (including, but not limited to, Texas franchise
Taxes and Texas sales and use Taxes). Seller covenants to deliver such
Certificate of No Tax due to Buyer as promptly as practicable after receipt of
such certificate.
