ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.
 
  On July 23, 1998, Boots & Coots International Well Control, Inc. (the
"Company"), completed the acquisition of 100% of the outstanding shares of
common stock of Elmagco, Inc., a Delaware Corporation ("Elmagco") from
Begemann, Inc., a Delaware Corporation ("Begemann"). Elmagco and its
subsidiaries conduct business using the tradename Baylor Company ("Baylor").
Baylor is engaged in the design and manufacture of electrical braking and
control equipment predominantly used in the drilling and marine markets,
highly engineered specialty products such as SCR systems and custom pedestal
leg locking systems for the offshore market. Additionally, Baylor designs and
manufactures a broad line of custom AC generators, which are used in a variety
of industrial, commercial and governmental applications.
 
  Consideration for the acquisition of Baylor with a June 30, 1998 effective
date was $25,000,000 in cash, retirement of $7,654,000 in secured indebtedness
of Baylor and the issuance at closing of 540,443 shares of the Company's
common stock. Concurrent with the acquisition, and to provide the Company with
cash to fund the acquisition and for other corporate purposes, the Company
completed the sale of $15,000,000 Senior Secured Notes due January 23, 1999
(the "Senior Notes") to The Prudential Insurance Company of America
("Prudential") and $30,000,000 of 11.28% Senior Subordinated Notes due July
23, 2006 (the "Subordinated Notes"). Proceeds from these financing
transactions were used to fund the Baylor acquisitions, repay $5,000,000 in
bridge financing provided through Prudential Securities Credit Corporation on
July 6, 1998 and provide working capital.
 
  The Senior Notes bear interest at the Eurodollar Rate plus 5.5% during the
first ninety days after issuance, the Eurodollar Rate plus 7.5% for the next
thirty days, and thereafter the interest rate increases by an additional 1.0%
for each thirty day period. The Senior Notes are secured by a first priority
lien on substantially all of the assets of the Company and its subsidiaries
and are guaranteed by the domestic subsidiaries of the Company. The
Subordinated Notes are similarly secured and guaranteed but are subordinate in
right of repayment to the Senior Notes.
 
  The loan agreement relating to the Senior Notes requires that the Company
use its best efforts to cause the refinancing of the Senior Notes as soon as
possible and imposes certain restrictions on the Company's activities,
including, without limitation, with respect to the payment of dividends or
other distributions on its capital stock; incurring additional indebtedness;
granting liens to secure any other indebtedness; making loans or advances to,
or investments in, other persons or entities; liquidating, dissolving or
merging with another company; dispositions of assets; transactions with
affiliates; changing the nature of its business; and the issuance of
additional shares of preferred stock.
 
  The Subordinated Note and Warrant Purchase Agreement relating to the
Subordinated Notes imposes restrictions on the Company's activities which are
similar to those imposed by the Senior Loan Agreement but additionally
requires that the Company meet certain minimum financial tests so long as the
Subordinated Notes are outstanding.
 
  The Senior Loan Agreement and the Subordinated Note and Warrant Purchase
Agreement also provide for customary events of default, the occurrence of
which could result in the acceleration of the Company's obligations under such
agreements and foreclosure on the collateral securing such obligations.
 
  In conjunction with the sale of the Notes, the Company issued to Prudential
a warrant to purchase 3,165,396 shares of common stock (the "Warrant") of the
Company at an initial exercise price of $6.70 per share. The Warrant contains
anti-dilution and repricing provisions that may result in downward adjustments
to the exercise price upon the occurrence of certain events and a provision
for the "cashless" exercise of the Warrant. The Company granted Prudential a
one-time demand registration right and unlimited "piggyback" registration
rights for the shares of common stock issuable upon the exercise of the
Warrant. The Company and certain stockholders of the Company also agreed with
Prudential that in the event of significant sales of securities of the Company
by the Company or such stockholders, Prudential would be entitled to
participate in such sale.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
  The following unaudited pro forma consolidated balance sheet of the Company
as of March 31, 1998 and the unaudited pro forma consolidated statements of
operations of the Company for the three months ended March 31, 1998, the six
months ended December 31, 1997 and the twelve months ended June 30, 1997 (the
"Unaudited Pro Forma Consolidated Financial Statements") give effect to (i)
the Baylor acquisition under the purchase method of accounting, (ii) the
issuance of 540,443 shares of common stock by the Company (iii) the payment of
$25,000,000 in cash and repayment of $7,654,000 of Baylor secured debt from
proceeds provided by $45,000,000 senior secured and senior subordinated debt
financing for the Company closed on July 23, 1998. The Unaudited Pro Forma
Consolidated Financial Statements also give effect to (iv) the acquisition of
Boots & Coots L.P., ABASCO, Inc., ITS Supply Corporation and Code 3, Inc. (the
"Acquired Entities") under the purchase method of accounting, and (v) the
borrowing by the Company of $4,250,000 and $1,000,000 plus an estimated
$500,000 for a financial advisory arrangement, pursuant to which the note
holders are to provide advisory services over a three-year period, to finance
the acquisition of ITS Supply Corporation. The Unaudited Pro Forma
Consolidated Statements of Operations take into effect the issuance of shares
of common stock under a private placement, issuance of 12% senior subordinated
debt and the related costs of conversion into common shares and the addition
of debt for the year ended June 30, 1997, the six months ended December 31,
1997 and the three months ended March 31, 1998.
 
  The unaudited pro forma consolidated statements of operations for the three
months ended March 31, 1998, the six months ended December 31, 1997 and the
twelve months ended June 30, 1997 were prepared assuming that the transactions
described above were consummated as of the beginning of each period presented.
The unaudited pro forma consolidated balance sheet as of March 31, 1998
includes the pro forma purchase accounting entries for the Baylor acquisition
and was prepared assuming that the transactions described in (i), (ii) and
(iii) above were consummated as of March 31, 1998.
 
  The Unaudited Pro Forma Consolidated Financial Statements are based upon the
historical consolidated and combined financial statements of the Company,
Baylor and each of the Acquired Entities described above and should be read in
conjunction with those consolidated and combined financial statements and
historical summary and the notes thereto. The results of the interim periods
presented are not necessarily indicative of the results to be expected for the
full year.
 
  The pro forma adjustments and the resulting Unaudited Pro Forma Consolidated
Financial Statements have been prepared based upon available information and
certain assumptions and estimates deemed appropriate by the Company. A final
determination of required purchase accounting adjustments, and the allocation
of the purchase price to the assets acquired and liabilities assumed based on
their respective fair values, has not yet been made for the Baylor
acquisition. Accordingly, the purchase accounting adjustments for the Baylor
acquisition reflected in the pro forma information are preliminary and have
been made solely for purposes of developing such information. The Company's
management believes, however, that the pro forma adjustments and the
underlying assumptions and estimates reasonably present the significant
effects of the transactions reflected thereby and that any subsequent changes
in the underlying assumptions and estimates will not materially affect the
Unaudited Pro Forma Consolidated Financial Statements presented herein. The
Unaudited Pro Forma Consolidated Financial Statements do not purport to
represent what the Company's consolidated financial position or consolidated
results of operations that actually would have resulted had the Baylor
acquisition occurred on the dates indicated or to project the Company's
consolidated financial position or consolidated results of operations for any
future date or period. Furthermore, the Unaudited Pro Forma Consolidated
Financial Statements do not reflect changes that may occur as the result of
post-combination activities and other matters.

                    THE SIX MONTHS ENDED DECEMBER 31, 1997
                       AND THE YEAR ENDED JUNE 30, 1997
 
1. BASIS OF PRESENTATION
 
  The unaudited pro forma consolidated balance sheet is presented assuming the
Baylor acquisition occurred on March 31, 1998. The unaudited pro forma
consolidated statements of operations for the year ended June 30, 1997, the
six months ended December 31, 1997 and the three months ended March 31, 1998
are presented as if the Baylor acquisition and the Boots & Coots L.P., ABASCO,
Inc., ITS Supply Corporation, and Code 3, Inc. acquisitions (the
"Acquisitions") occurred at the beginning of each period presented. The
unaudited pro forma consolidated statements of operations may not necessarily
be indicative of the results which would actually have occurred if the
Acquisitions actually had been in effect on the date or for the periods
indicated or which may result in the future.
 
2. PRO FORMA ADJUSTMENTS
 
  (a) ABASCO, Inc.--The adjustments represent the revenues, operating

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholder
Elmagco, Incorporated:
 
  We have audited the accompanying consolidated balance sheets of Elmagco,
Incorporated dba Baylor Company and subsidiaries (wholly-owned by Begemann,
USA, Inc.) as of December 31, 1997 and 1996, and the related consolidated
statements of operations, stockholder's equity and cash flows for the years
then ended. These consolidated financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Elmagco,
Incorporated and subsidiaries as of December 31, 1997 and 1996, and the
results of their operations and their cash flows for the years then ended, in
conformity with generally accepted accounting principles.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 (a) Organization and Principal Business Activities
 
  Elmagco Incorporated and subsidiaries (the Company) was formed in the state
of Delaware in 1996 for the sole purpose of merging Baylor Company and
Subsidiaries (Baylor Company) into itself. The Company continues doing
business as Baylor Company. In 1996, the Company formed a subsidiary, Baylor
Company Limited (wholly-owned by Baylor Company) in Aberdeen, Scotland. The
Company is engaged in the design and manufacture of electrical braking and
control equipment used predominantly in the drilling and marine markets,
highly engineered specialty products such as SCR systems and custom pedestal
leg locking systems and thruster systems for the offshore market.
Additionally, the Company designs and manufactures a broad line of custom AC
generators which are used in a variety of industrial, commercial and
governmental applications. The Company's customers are in the petroleum, power
generation, government and utility industries at December 31, 1997 and 1996.
The Company's sales are made to both international and domestic concerns. The
majority of the trade receivables were with customers in the South Central
United States and various international locations, primarily Canada,
Singapore, and the North Sea.
 
  On December 23, 1997, the Company entered into an agreement with Schottel-
Werft Josef Becker Gmbh & Co. KG, a German company, to form a joint venture,
Schottel, Inc., a Delaware corporation. Each of the joint venture partners has
a 50% interest in Schottel, Inc. The joint venture is engaged in the selling
and servicing of thrusters to the drilling and marine markets in North
America.
 
  The Company is wholly-owned by Begemann, Inc. (Begemann) and was formed in
1989 under the name Baylor Technology, Inc. to acquire the business and
certain assets and liabilities of the Baylor Company. During 1992, the Company
changed its name to Baylor Company. Begemann is a wholly-owned subsidiary of
the Royal Begemann Group N.V. and was organized pursuant to the laws of the
state of Delaware.
 
 (b) Principles of Consolidation
 
  The consolidated financial statements include the accounts of Elmagco
Incorporated and its wholly-owned subsidiaries, Baylor Electronics, Inc.
(BEI), ICC/Baylor, Inc. (ICC) and Baylor, Ltd. All significant intercompany
balances and transactions have been eliminated in consolidation.
 
 (c) Cash and Cash Equivalents
 
  Cash and cash equivalents includes short-term investments with the original
maturity of three months or less.
 
 (d) Inventories
 
  Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out (FIFO) method.
 
 (e) Property and Equipment
 
  Property and equipment are stated at cost and are depreciated using the
straight-line method over the estimated useful lives of the assets of five to
twelve years.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 (f) Other Assets
 
  Included in other noncurrent assets is a brake design technology of
$1,600,000, which is being amortized using the straight-line basis over an
estimated useful life of fourteen years. Annual amortization expense amounted
to approximately $114,000 in 1997 and 1996.
 
 (g) Revenue Recognition
 
  The Company recognizes profits on long-term contracts on the percentage-of-
completion and completed contract methods of accounting on a contract per
contract basis.
 
  At December 31, 1997, all significant open contracts were accounted for
under the completed contract method. The completed contract method is used
when a lack of dependable estimates and inherent hazards may cause forecasts
to be unreliable. A contract is considered to be complete when all costs
except insignificant items have been incurred and the installation is
operating according to specifications or has been accepted by the customer.
 
  Contract costs include all direct material and labor costs and those
indirect costs related to contract performance, such as indirect labor,
supplies, tools, repairs, and depreciation costs. General and administrative
costs are charged to expense as incurred. Provisions for estimated losses on
uncompleted contracts are made in the period in which such losses are
determined.
 
  Costs in excess of amounts billed are classified as current assets under
costs in excess of billings on uncompleted contracts. Billings in excess of
costs are classified under current liabilities as billings in excess of costs
on uncompleted contracts. Contract retentions are included in accounts
receivable.
 
 (h) Income Taxes
 
  The Company is included in the consolidated federal income tax return of
Begemann. For financial reporting purposes, the Company records income tax
expense or benefit as if a separate return were filed.
 
  The Company follows the asset and liability method of accounting for income
taxes. Under the asset and liability method, deferred income taxes are
recognized for the tax consequences of "temporary differences" by applying
enacted statutory rates to applicable future years to differences between
financial statement carrying amounts and the tax bases of existing assets and
liabilities. The effect on deferred taxes of a change in tax rates is
recognized in income in the period that includes the enactment date.
 
 (i) Foreign Currency Translation
 
  The functional currency for the Company's foreign operations is the
applicable local currency. Translation from applicable foreign currencies to
U.S. dollars is performed on balance sheet accounts using exchange rates in
effect at the balance sheet date and for revenue and expense accounts using
primarily a weighted average exchange rate during the period. Adjustments
resulting from such translation are included as a separate component of
stockholder's equity.
 
 (j) Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
 
                                      22

                           STOCK PURCHASE AGREEMENT


     THIS STOCK PURCHASE AGREEMENT ("Agreement") is made as of the 22nd day of
June 1998, by and among Elmagco, Inc., a Delaware corporation ("Elmagco"), with
its principal place of business at 500 Industrial Blvd., Sugar Land, Texas
77478; Begemann, Inc., a Delaware corporation ("Seller"), with its principal
place of business at 500 Industrial Blvd., Sugar Land, Texas 77478 and Boots &
Coots International Well Control, Inc., a Delaware corporation, with its
principal place of business at 5151 San Felipe, Suite 450, Houston, Texas 77056
("Buyer").

                                R E C I T A L S

     WHEREAS, Seller is the owner of all of the outstanding capital stock of
Elmagco; and

     WHEREAS, on the terms and conditions set forth in this Agreement, Seller
desires to sell to Buyer, Elmagco desires to induce Buyer to purchase from
Seller and Buyer desires to purchase from Seller, all of the issued and
outstanding capital stock of Elmagco, which owns (except as set forth on
Schedule 3.5) all of the issued and outstanding capital stock of its
subsidiaries, Baylor Electronics, Inc., a Texas corporation; Baylor Controls,
Inc., a Texas corporation; Baylor Limited, a United Kingdom corporation; and
Schottel, Inc., a Delaware corporation (being collectively referred to herein as
the "Subsidiaries" and individually as a "Subsidiary");

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants, representations, warranties and conditions herein contained, the
parties hereby agree as follows:

                    ARTICLE I.  PURCHASE AND SALE OF SHARES

     1.1  Purchase and Sale. Upon the terms and subject to the conditions
provided herein in reliance on the representations, warranties and covenants
hereinafter set forth, on the Closing Date (as defined in Section 2.1 hereof),
Seller agrees to transfer and convey to Buyer,
<PAGE>
 
and Buyer agrees to acquire from Seller all of the issued and outstanding shares
of capital stock of Elmagco (the "Shares").
 
     1.2  Purchase Price. In consideration for the sale and transfer of the
Shares, Buyer shall pay to Seller, at the times and in the manner herein
provided, a purchase price of Thirty Million Dollars (US $30,000,000), less the
amount of the Dividend (as defined below) and subject to further adjustment as
herein provided (the "Purchase Price"), which Purchase Price shall consist of
(i) cash in the amount equal to (a) the lesser of $25,000,000 or the Purchase
Price (b) less the amount necessary to result in the issuance of shares of the
common stock, $.00001 par value per share ("Common Stock"), of Buyer to Seller
with a value, for purposes hereof, of at least $3,000,000, and (ii) shares of
Common Stock of Buyer with a value, for purposes hereof, equal to the greater of
(a) $3,000,000 or (b) the difference between the cash portion of the Purchase
Price and the Purchase Price. The number of shares of Common Stock to be issued
to Seller in satisfaction of the preceding sentence, shall be determined by
calculating the average of the last reported sales price per share (or the
average of the closing bid and asked prices if no sales have been reported) of
Buyer's Common Stock for each trading day within the thirty (30) calendar days
immediately preceding the Closing Date and dividing such number into the dollar
value thereof to be delivered to Seller as determined above. For example, if the
Dividend were $1,500,000, the Purchase Price would be $28,500,000, and the
difference between the Purchase Price and the cash portion of the Purchase Price
would be $3,500,000 (since the cash portion of the Purchase Price cannot exceed
$25,000,000). If the average of the last reported sales price per share for such
period were $5.00, the number of shares would be calculated as follows:
 
 
 

                                       2
<PAGE>
 
          Difference between cash portion of the Purchase Price
          and aggregate Purchase Price                             $ 3,500,000

          Divided by Average Sales Price                           $         5
                                                                   -----------
          Aggregate Shares                                             700,000

For the purposes hereof, the term "Dividend" shall mean the amount, not to
exceed $2,000,000, distributed by Elmagco to Seller prior to Closing (and after
the Effective Date) as a dividend (exclusive of the amount treated as a dividend
under Section 5.1(g)), which shall equal Seller's good faith estimate of
Elmagco's after tax net income from operations for the period from January 1,
1998 through June 30, 1998 (the "Effective Date") computed in accordance with
Generally Accepted Accounting Principles, consistently applied.

     1.3  Preparation of Initial and Final Effective Date Financial Statements.
Elmagco shall engage KPMG Peat Marwick LLP to prepare audited financial
statements of Elmagco as of the Effective Date (the "Initial Effective Date
Financial Statements").  The Initial Effective Date Financial Statements shall
include a closing balance sheet of Elmagco (the "Initial Effective Date Balance
Sheet") which shall reflect those assets and liabilities of Elmagco normally
reflected on a balance sheet prepared in accordance with generally accepted
accounting principles, consistently applied, and which assets and liabilities
are divided among the same categories of assets and liabilities contained on the
balance sheet of Elmagco as of December 31, 1997 (the "Base Balance Sheet").
The costs of such audit shall be paid one-half by Buyer and one-half by Seller.

     As soon as reasonably practicable after the Closing Date and in any event
no later than sixty (60) days after the Closing Date, the Initial Effective Date
Financial Statements shall be delivered to Buyer.  Upon receipt of the Initial
Effective Date Financial Statements, Buyer and its independent accountants
("Buyer's Accountants") shall be permitted during the succeeding thirty (30) day
period to examine such books, records and work papers as reasonably necessary 

                                       3
<PAGE>
 
in connection with its review of the Initial Effective Date Financial
Statements. If Buyer agrees to the Initial Effective Date Financial Statements,
they shall become the Final Effective Date Financial Statements. If Buyer cannot
agree to the Initial Effective Date Financial Statements it shall within such
thirty (30) day period prepare and deliver to Seller a list of disputed
adjustments (the "Disputed Adjustments") Buyer believes should have been
recorded on such financial statements. Buyer and Seller shall use their best
efforts to resolve the Disputed Adjustments. If Buyer and Seller are unable to
reach an agreement on the Disputed Adjustments within thirty (30) calendar days
after receipt by Seller of the Disputed Adjustments, then the Disputed
Adjustments shall be submitted by Buyer and Seller to their independent public
accountants on or before the thirty-first (31st) calendar day after receipt by
Seller of the Disputed Adjustments, and the parties shall use reasonable efforts
to cause these accounting firms to promptly review and assist the parties in
resolving the Disputed Adjustments. Buyer and Seller shall each be responsible
for the fees, costs and expenses of their respective public accountants. If the
independent accountants for Buyer and Seller are unable to reach an agreement on
the Disputed Adjustments within fifty (50) calendar days after receipt by Buyer
of such Disputed Adjustments, then the Disputed Adjustments shall be resolved by
a nationally-recognized firm of certified public accountants mutually acceptable
to the independent accountants of Buyer and Seller (the "Accounting Referee").
The parties shall use reasonable efforts to cause the Accounting Referee to
promptly review the Disputed Adjustments and determine the final value of each
of the Disputed Adjustments. In making such determination, the Accounting
Referee shall consider only the items or amounts in dispute (and any other items
or amounts relating thereto). Such determination shall be made within thirty
(30) calendar days after the date on which the Accounting Referee receives
notice of the Disputed Adjustments, or as soon thereafter as possible. Upon the
resolution of all Disputed Adjustments, the Initial Effective Date Financial
Statements

                                       4
<PAGE>
 
shall then be amended to reflect the determination of the final value of each of
the Disputed Adjustments and shall become the Final Effective Date Financial
Statements and the balance sheet contained therein shall become the Final
Effective Date Balance Sheet. The fees, costs and expenses of the Accounting
Referee in conducting such review shall be shared one-half by Buyer and one-half
by Seller.

     The Final Effective Date Financial Statements shall be deemed to be and
shall be conclusive and binding on the parties to this Agreement for purposes of
determining any adjustment of the Purchase Price pursuant to Section 1.4.

     1.4  Purchase Price Adjustment. The Purchase Price shall be adjusted
downward to the extent that the Stockholder's Equity of Elmagco reflected on the
Final Effective Date Balance Sheet (adjusted as hereafter provided) is less than
$13,278,481 (which is the amount of Stockholder's Equity reflected on the Base
Balance Sheet); provided, however that such adjustment shall be made only if
such difference exceeds $300,000. The Stockholder's Equity reflected on the
Final Effective Date Balance Sheet shall be increased by the amount of any
Seller Liabilities (as defined in Section 9.1) reflected on the Final Effective
Date Balance Sheet, plus the amount of any reserves for Seller Liabilities (as
defined in Section 9.1) in excess of $317,000 which are established in
preparation of the Final Effective Date Balance Sheet. In the event the Final
Effective Date Balance Sheet has not been prepared by the Closing Date, Seller
shall make a good faith estimate of the Stockholder's Equity of Elmagco as of
such date and the parties shall adjust the Purchase Price accordingly;
thereafter, upon completion of the Final Effective Date Balance Sheet, Seller or
Buyer, as appropriate, shall pay the difference between the amount of the
adjustment for Stockholder's Equity made on the Closing Date and the amount of
the adjustment required based upon the Final Effective Date Balance Sheet. With
respect to the foregoing adjustment, the net amount of the required payment
shall be made in cash within

                                       5
<PAGE>
 
five business days after such determination has been made. The amount, if any,
required to be paid pursuant to this Section 1.4 shall bear interest, at the
prime rate announced from time to time by The Wall Street Journal from the
Closing Date through the date of payment of such amount, and the total amount of
such interest shall be paid at the same time and along with such payment.

     1.5  Method of Payment. On the Closing Date, Buyer shall pay to Seller the
cash portion of the Purchase Price by wire transfer of immediately available
funds to an account designated by Seller not fewer than three (3) business days
prior to the Closing Date and shall instruct its transfer agent to issue or
cause to be issued in the name of Seller the portion of the Purchase Price to be
paid in shares of Buyer's Common Stock.

     1.6  338(h)(10) Election; Tax Liability; Allocation of Purchase Price. At
the request of Buyer, Seller will cooperate with Buyer in making a timely and
effective election under Section 338(h)(10) of the Code, with respect to the
purchase and sale of the Shares hereunder. Upon presentation of Internal Revenue
Service Form 8023 by Buyer to Seller, Seller will, within fifteen (15) days
after the such presentation, execute and deliver said Form 8023 to Buyer. If any
changes or supplements are required to the Form 8023, Seller agrees to make such
changes or supplements. Except as specifically provided herein, any income or
Texas franchise tax liabilities of either Seller or Elmagco (including any
interest and penalties) incurred as a result of the Section 338(h)(10) election
will be the responsibility of Seller. Seller shall be responsible for the
payment of all taxes related to taxable income of the Company during the period
from January 1, 1998 until the Closing Date. Buyer and Seller agree that the
Purchase Price, as adjusted, shall be allocated among the Purchased Assets and
the Noncompete Agreement (as hereinafter defined) in such manner as Seller and
Buyer shall mutually agree at or prior to the Closing, provided such allocation
will be in accordance with the requirements of Section 1060 of the Internal
Revenue Code and the rules and regulations promulgated thereunder. Seller and
Buyer shall cooperate in

                                       6
<PAGE>
 
making a reasonable allocation of the Purchase Price and all tax returns and
reports filed by Seller, Elmagco and Buyer shall be consistent with the agreed
allocations.

                             ARTICLE II.  CLOSING

     2.1  The Closing. The transactions contemplated in this Agreement are to be
closed, and all deliveries to be made at such time in connection therewith are
to be made, at the offices of Brown, Parker & Leahy, L.L.P., 1200 Smith Street,
Suite 3600, Houston, Texas 77002 on July 15, 1998 at 10:00 a.m. local time, or
at such other place, date and/or time as may be mutually agreed upon in writing
by Seller and Buyer (said closing and the date thereof herein referred to as the
"Closing" and the "Closing Date," respectively). The Closing shall be deemed to
have occurred and be effective for all purposes as of 12:01 a.m., Houston time,
on the Closing Date.

     2.2  Termination.

     Notwithstanding anything contained in this Agreement to the contrary, this
Agreement may be terminated at any time prior to the Closing:

          (a) By the mutual written consent of Buyer and Seller;

          (b) By either Buyer or Seller by notice delivered to the other if the

     Closing shall not have occurred on or before July 15, 1998; provided,
     however, that any such termination of this Agreement pursuant to this
     Section 2.2 shall not relieve Buyer of any liability to Seller for any
     breach of the provisions of Section 2.3 hereof; or

          (c) By either Buyer or Seller by notice delivered to the other if
     there shall have been entered a final, nonappealable order or injunction of
     any governmental authority restraining or prohibiting the consummation of
     the transactions contemplated herein or any material part thereof.

                                       7
<PAGE>
 
In the event of termination of this Agreement each party hereto will pay all of
its own fees and expenses and there will be no further liability hereunder on
the part of any party hereto, except under Section 2.3.

     2.3  Breakup Fee. If Buyer fails to consummate the transactions
contemplated herein on or before July 15, 1998 (unless extended in writing by
Seller and Buyer), except for the reasons enumerated below, Buyer shall pay
Seller cash in the amount of $1,000,000. Buyer shall not be required to pay such
amount in the event such failure to close is the result of any of the following:

     (i)      a material adverse change occurs, in comparison with the same as
of December 31, 1997, in or to: the financial condition, operations or business
prospects of Elmagco and the Subsidiaries, taken as a whole; the fair market
value of Elmagco's and the Subsidiaries' assets; or the amount of Elmagco's and

     As an inducement to Buyer to enter into this Agreement and to consummate
the transactions contemplated herein, Seller and Elmagco, jointly and severally,
represent and warrant to Buyer as follows:

     3.1  Organization, Good Standing and Qualification. Seller is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority to own,
lease and operate its properties and conduct its business as currently being
conducted by it. Elmagco is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware and has all requisite
corporate power and authority to own, lease and operate its properties and
conduct its business as currently being conducted by it. Elmagco is duly
qualified to do business and is in good standing in such jurisdictions as the
nature of its business or ownership, leasing or operation of its assets so
requires, except where the failure to so qualify would not have a material
adverse effect on Elmagco or its business. Each jurisdiction in which Elmagco is
qualified to do business is listed on Schedule 3.1 hereto.

     3.2  Authorization. Each of Seller and Elmagco has the corporate power and
authority to execute, deliver and perform this Agreement and all other
instruments and documents required or contemplated pursuant to this Agreement
and to carry out its respective obligations hereunder and thereunder. Such
execution, delivery and performance by Seller or Elmagco have been duly
authorized by all necessary corporate and other action by each of Seller and
Elmagco as required under applicable law and this Agreement is, and such
instruments and documents when executed and delivered pursuant hereto will be,
the legal, valid and binding obligations of Seller and Elmagco, as the case may
be, enforceable against Seller and Elmagco, as the case may be, in

                                       9
<PAGE>
 
accordance with their respective terms, except as enforceability may be limited
by bankruptcy laws, insolvency laws and laws generally relating to the rights of
creditors.

     3.3  Capital of Elmagco. The authorized capital stock of Elmagco consists
of 2,000 shares of common stock, having a par value of $1.00 each, of which
1,000 shares are issued and outstanding and 1,000 shares of preferred stock,
having a par value of $1.00 each, none of which are issued and outstanding. All
of the Shares are validly issued, fully paid and non-assessable. There are no
outstanding subscriptions, options, rights, warrants, convertible securities, or
other agreements or commitments obligating Elmagco to issue or to transfer from
treasury any additional shares of its capital stock of any class.

     3.4  Title. Seller is the owner, beneficially and of record, of all the
Shares free and clear of all liens, encumbrances, security agreements, equities,
options, claims, charges and restrictions, except those set forth on Schedule
3.4.

interest or investment (whether equity or debt) in any corporation, partnership,
business, trust, or other entity, except the Subsidiaries. Except as set forth
on Schedule 3.5, Elmagco owns, beneficially and of record, all of the issued and
outstanding capital stock of each Subsidiary. Each Subsidiary is a corporation
duly organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation, has all necessary power to own its assets and to
carry on its business as presently conducted, and is duly qualified to do
business and is in good standing in each jurisdiction in which the nature of its
business or of its properties makes such qualification necessary, except where
the failure to so qualify would not have a material adverse effect on such
Subsidiary or its business. Each jurisdiction in which each Subsidiary is
qualified to do business is set forth on Schedule 3.5 hereto. All the issued and
outstanding shares of capital stock of each Subsidiary are validly issued, fully
paid and non-assessable, and are owned by Company, free and

                                       10
<PAGE>
 
clear of all liens, encumbrances, security agreements, equities, options,
claims, charges and restrictions. There are no outstanding subscriptions,
options, rights, warranties, convertible securities or other agreements or
commitments obligating any Subsidiary to issue or to transfer from treasury any
additional shares of its capital stock of any class.

     3.6  No Violation. Subject to Elmagco obtaining the Consents (as set forth
in Section 3.29), neither the execution, delivery or performance of this
Agreement or any instrument or document contemplated herein nor the consummation
of the transactions contemplated herein or therein will constitute a violation
of, or be in conflict with, or will result in a cancellation of, or constitute a
default under, or create (or cause the acceleration of the maturity of) any
debt, obligation or liability affecting, or result in the creation or imposition
of any security interest, lien, or other encumbrance upon the Shares or any of
the assets of Elmagco or any Subsidiary under:

          (a) any term or provision of the Certificate or Articles of
Incorporation or Bylaws of Seller, Elmagco or any Subsidiary;

          (b) any judgment, decree, order, regulation or rule of any court or
governmental authority;

          (c)  any statute or law;

          (d) any contract, agreement, indenture, lease or other commitment to
which Seller, Elmagco or any Subsidiary is a party or by which Seller, Elmagco
or any Subsidiary, as the case may be, is bound; or

          (e) cause any material change in the rights or obligations of any
party under any such contract, agreement, indenture, lease or commitment.

Except as provided in Section 3.29 hereof, no consent of, or notice to, any
federal, state or local authority, or any private person or entity, is required
to be obtained or given by Seller or Elmagco in

connection with the execution, delivery or performance of this Agreement or any
other instrument or document to be executed, delivered or performed hereunder by
Seller or Elmagco.

     3.7  Title to Assets. Elmagco and the Subsidiaries have good, marketable
and valid title in and to all of their respective assets, free and clear of any
lien, mortgage, security interest, pledge or other encumbrance, except for those
set forth on Schedule 3.7 (the "Permitted Liens").

     3.8  Condition of Assets. All of the tangible assets of Elmagco and the
Subsidiaries are in good operating condition and repair and are useable for the
purposes for which they were intended, except for reasonable wear and tear and
except to the extent of applicable reserves for repair or replacement of such
assets and, to the knowledge of Seller, such assets conform to all applicable
statutes, ordinances and regulations relating to their construction, use and
operation. All buildings and other similar structures used by Elmagco or the
Subsidiaries are free from material defects except to the extent of any
applicable reserves established for repair or replacement.

     3.9  Accounts Receivable. Attached hereto as Schedule 3.9 is an accurate
aging schedule of all accounts receivable of Elmagco and the Subsidiaries
through May 31, 1998, except for accounts receivable from Seller and its
affiliates. Such accounts receivable are collectible at the recorded amounts
thereof, net of any allowance for doubtful accounts reflected on the Base
Balance Sheet or subsequently recorded on the books and records of Elmagco and
the Subsidiaries. Such accounts receivable, and all accounts receivable created
after that date, arose from valid sales in the ordinary course of business and
are collectible in the ordinary course of business, subject in the aggregate to
any applicable allowance for doubtful accounts which is consistent with
historical levels.

     3.10 Insurance Policies. Schedule 3.10 is a true and accurate list and
summary of current insurance coverage or information concerning any self
insurance program with respect to

                                       12
<PAGE>
 
Elmagco and the Subsidiaries. Insurance policies providing such coverage will be
outstanding and in full force and effect through the Closing Date. Neither
Elmagco and the Subsidiaries nor Seller has received notice from any current
insurance carrier of the intention of such carrier (i) to discontinue any
material insurance coverage afforded to such companies; or (ii) to materially
increase the premium costs of such insurance. The types of insurance policies
maintained by Elmagco and the Subsidiaries or Seller with third parties for the
benefit of Elmagco and the Subsidiaries, and the coverage afforded by such
policies with respect to the operations of Elmagco and the Subsidiaries are, in
the opinion of Seller and Elmagco, reasonable in light of the nature of the
business conducted and the risks associated with such business. Except as listed
on Schedule 3.10, during the past year, no application by Seller or Elmagco or
the Subsidiaries for insurance or any bond has been denied for any reason.

Section 4971 through 4980B of the Code or civil liability 

                                       14

binding obligation of the parties thereto in accordance with the terms of such
Contract. There have been no material amendments, modifications or supplements
to any Contract, except as set forth on Schedule 3.20. There is no default or
claim of default under any Contract and, no event has occurred that, with the
passage of time or the given of notice (or both), would constitute a default by

lien, mortgage or any encumbrance on any of the assets of Elmagco or any

to be acquired by Seller as part of the Purchase Price pursuant to this
Agreement are being or will be acquired for its own account and with no
intention of distributing or reselling such securities or any part thereof in
any transaction that would be in violation of the securities laws of the United
States of America, or any state, without prejudice, however, to the rights of
Seller at all times to sell or otherwise dispose of all or any part of such
securities under an effective registration statement under the Securities Act,
or under an exemption from such registration available under

                                       26
<PAGE>
 
the Securities Act of 1933, as amended (the "Securities Act"), and subject,
nevertheless, to the disposition of Seller's property being at all times within
its control. If Seller should in the future decide to dispose of any of such
shares of Common Stock, Seller understands and agrees that it may do so only in
compliance with the Securities Act and applicable state securities laws, as then
in effect. Seller agrees to the imprinting, so long as required by law of a
legend on certificates representing such shares to the following effect:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE
     SECURITIES LAWS OF ANY STATE.  THE SECURITIES MAY NOT BE TRANSFERRED EXCEPT
     PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND
     APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION
     FROM THE REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS SUPPORTED BY A
     WRITTEN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH
     REGISTRATION IS NOT REQUIRED.

Seller understands that any shares of Common Stock of Buyer issued to it will
not be registered at the time of their issuance under the Securities Act for the
reason that the sale provided for in this Agreement is exempt pursuant to
Section 4(2) of the Securities Act and that the reliance of Buyer on such
exemption is predicated in part on the representations of Seller set forth
herein.  Seller represents that it is experienced in evaluating companies such
as Buyer, has such knowledge and experience in financial and business matters as
to be capable of evaluating the merits and risks of its investment and has the
ability to suffer the total loss of its investment.  Seller further represents
that it has had the opportunity to ask questions of and receive answers from
executive officers of Buyer concerning the terms and conditions of the offering
and to obtain additional information to the satisfaction of Seller.  Seller is
an "accredited investor  as that term is defined by Rule 501 of Regulation D
promulgated under the Securities Act.

     Buyer acknowledges and agrees that, subject to receipt by Buyer of an
opinion of counsel of Winstead Sechrest & Minick P.C. that the applicable
transfer may be made without registration 

                                       27
<PAGE>
 
under the securities laws of the United States of America or any state and will
not cause the initial issuance of the Common Stock to Seller to have been made
in violation of the securities laws of the United States of America or any
state, any one or more of the following transfers of such shares of Common Stock
may be made:

     (a)  Seller may transfer shares to one or more shareholders of Seller
          ("Shareholder") pursuant to a complete redemption of such
          Shareholder's stock in Seller and/or a payment on Seller's
          indebtedness owed to such Shareholder;
     (b)  Seller or a Shareholder may transfer shares to a direct or indirect
          80%-or-more-owned subsidiary of Seller or such Shareholder (and
          thereafter such subsidiary may retransfer such shares to Seller or
          such Shareholder);
     (c)  a Shareholder may transfer shares to one or more of its shareholders.

than 5% of the combined sales of Elmagco or the Subsidiaries during the year
ended as of the date of the Base Balance Sheet, or during the three Months ended

                        OTHER POST-CLOSING OBLIGATIONS

     9.1  General Indemnity.

          (a) Seller agrees to reimburse, hold harmless, indemnify and defend
Buyer and its officers, directors, controlling persons (if any), employees,
attorneys, agents, partners

                                       42
<PAGE>
 
representatives, successors and assigns (the "Buyer Indemnitees") from and
against any loss, suit, claim, action, cause of action, proceeding (formal or
informal), investigation, judgment, deficiency, actual or punitive damage,
settlement, liability, expense or cost of any kind or amount whatever, including
court costs and reasonable attorneys' fees (collectively, "Claims") which
results from or arises out of or is based upon:

              (i)    the inaccuracy of any representation or warranty made by
          Seller or Elmagco (other than Section 3.14 which is covered in Section
          9.1(a)(iii) below), or the failure to perform or breach by Seller or
          Elmagco of any covenant, obligation or agreement contained in this
          Agreement, the Exhibits or Schedules hereto, the bring-down
          certificate required by Section 8.1(d) and any amendments that may be
          entered into;

              (ii)   any pending or threatened litigation, claim or assessment
          against Elmagco (including but not limited to any claim based on tort
          liability, product liability, warranty, negligence or strict
          liability) designated by Buyer, in its sole discretion, and set forth
          on Schedule 9.1 which is to be delivered by Buyer to Seller at Closing
          ("Seller's Liabilities"); provided, however, that Seller shall have no
          liability under this Section 9.1(a)(ii) until and only to the extent
          that the aggregate Claims under this Section 9.1(a)(ii) exceed
          $317,000; and

              (iii)  any inaccuracy of the representation set forth in Section
          3.14 or the failure of Seller to pay any taxes, including, without
          limitation, any Texas franchise tax liability accruing to either
          Elmagco or Seller, and any liability for gain or loss on the sale of
          Shares pursuant to this Agreement arising out of or related to the
          transactions contemplated in this Agreement.

                                       43

     ; provided further, however, that notwithstanding the other provisions of
this Article IX, (1) Seller shall have no obligation to indemnify any Buyer
Indemnitees with respect to any Claim unless Buyer notifies Seller of the claim
or potential claim for indemnification not later than the first anniversary of
the Closing Date for matters covered by Section 9.1(a)(i) and the third
anniversary of the filing of Seller's 1998 United States federal income tax
return (with attached Section 338(h)(10) election) for matters covered by
Section 9.1(a)(iii); (2) Seller shall have no obligation to indemnify Buyer for
any Claim under Section 9.1(a)(i) until the amount of such Claim equals or
exceeds $50,000 or the sum of all Claims equals or exceeds $100,000, at which
time Buyer shall have the right to indemnification for the full amount of each
such Claim; and (3) Buyer's sole recourse for indemnification of Claims under
Sections 9.1(a)(i) and 9.1(a)(iii) shall be against the Escrow Fund established
pursuant to Section 9.2. Provided further, that of the amount held in the Escrow
Fund, no more than $1,500,000 thereof may be paid out to satisfy claims made
pursuant to Section 9.1(a)(i). The entire amount of the Escrow Fund shall be
subject to being paid out to satisfy claims made pursuant to Section
9.1(a)(iii).

     The Indemnity Agreement contained in this Section 9.1(a) shall remain
operative and in full force and effect regardless of any investigation made by
or on behalf of Buyer. Any indemnification payments made to Buyer shall be
deemed an adjustment to the Purchase Price.

          (b) Buyer agrees to hold harmless, indemnify and defend Seller and its
officers, directors, controlling persons, employees, attorneys, agents,
representatives, successors and assigns (the "Seller Indemnitees") from and
against any loss, claim, cause of action, damage, liability, expense or cost of
any kind or amount whatever including court costs and reasonable attorneys' fees
which result from or arise out of the inaccuracy of any representation or
warranty made by Buyer, or the failure to perform or breach by Buyer of any
covenant, obligation or agreement 

                                       44
<PAGE>
 
contained in this Agreement, the Exhibits or Schedules hereto, the bring-down
certificate required by Section 8.2(c) and any amendments that may be entered
into.

     The Indemnity Agreement contained in this Section 9.1(b) shall remain
operative and in full force and effect, regardless of any investigation made by
or on behalf of Seller or Elmagco.  Any indemnification payments made by Buyer
to Seller shall be deemed an adjustment to the Purchase Price.

     9.2  Escrow. (a) The indemnification obligations of Seller under Sections
9.1(a)(i) and (iii) shall be secured by an escrow fund of the number of shares
of the Common Stock of Buyer, which is a portion of the Purchase Price, having a
value, as determined in Section 1.2, of $3,000,000 (the "Escrow Fund"), which
shall be held by a federally insured savings or banking institution mutually
acceptable to Buyer and Seller (the "Escrow Agent") pursuant to the terms of an
escrow agreement in form and substance satisfactory to Buyer and Seller (the
"Escrow Agreement"). The Escrow Agreement shall provide that Seller shall have
the right to receive any cash dividends paid, if any, on the shares of Common
Stock in the Escrow Fund.

          (b) In the event that any Buyer Indemnitee has a claim for
indemnification under this Article IX, Buyer shall give written notice of same
to Seller. If Seller has not corrected or remedied such claim within thirty (30)
days following receipt of such notice and does not dispute such claim, then
Buyer shall be entitled to receive immediately from the Escrow Fund an amount of
shares from the Escrow Fund having a value equal to the amount of such claim. If
Seller disputes such claim, Buyer shall not be entitled to receive any amount
from the Escrow Fund with respect to such claim prior to resolution of such
dispute pursuant to Article XI or otherwise, but any such delay shall be without
prejudice to any extension of the Escrow Fund pursuant to Section 9.2(c) hereof.
For purposes of valuing the shares of Common Stock for payment of any Claim,
such value shall be determined by calculating the average of the last 

                                       45
<PAGE>
 
reported sales price per share (or the average of the closing bid and asked
prices if no sales have been reported) of Buyer's Common Stock for each trading
day within the thirty (30) calendar days immediately preceding the date of
Buyer's notice of such Claim, or, if no such reports are rendered, the fair
market value of such shares over such period determined in good faith by the
Board of Directors of Buyer.

          (c) Provided no dispute then exists as to any claim by Buyer of all or
a portion of the Escrow Fund and provided all obligations of Seller to Buyer
which are payable from the Escrow Fund are satisfied, the remaining Escrow Fund
will be released to Seller on the three (3) year anniversary of the filing of
Seller's 1998 United States federal income tax return.  To the extent a dispute
does exist as to a claim or claims on such anniversary date, an amount equal to
the amount of such claim or claims will be withheld from such remaining Escrow
Fund and will continue to be held by the Escrow Agent pursuant to the terms of
the Escrow Agreement until such claim or claims have been fully resolved.

     9.3  Defense of Claims. If any Buyer Indemnitee or Seller Indemnitee (the
"Indemnified Party") desires to make a claim against the party obliged to
provide indemnification to such Indemnified Party (the "Indemnitor"), the
Indemnified Party shall give prompt notice in writing (a "Claim Notice") to the
Indemnitor describing in reasonable detail the facts giving rise to any claim
for indemnification hereunder promptly after the receipt of knowledge of the
facts upon which such claim is based (but in no event later than 10 days prior
to the time any response to the asserted claim is required). Upon receipt by the
Indemnitor of a Claim Notice from an Indemnified Party with respect to any claim
of a third party, such Indemnitor may control negotiations towards the
resolution of any such claim without the necessity for litigation, and, if
litigation ensues, assume the defense thereof at such Indemnitor's cost and with
counsel reasonably satisfactory to the Indemnified Party and the Indemnified
Party shall extend reasonable 

                                       46
<PAGE>
 
cooperation in the defense or prosecution thereof and shall furnish such
records, information and testimony and attend all such conferences, discovery
proceedings, hearings, trials and appeals as may be reasonably requested in
connection therewith. The Indemnified Party shall have the right to employ its
own counsel in any such case, but the fees and expenses of such counsel shall be
at the expense of the Indemnified Party unless (i) the Indemnitor shall not have
promptly employed counsel reasonably satisfactory to such Indemnified Party to
take charge of the defense of such action or (ii) such Indemnified Party shall
have reasonably concluded, based upon the opinion of its outside legal counsel,
that there may be one or more legal defenses available to it, or to any other
Indemnified Party who has submitted a Claim Notice to the Indemnitor, which are
different from or additional to those available to the Indemnitor, in either of
which events such fees and expenses shall be borne by the Indemnitor (but in no
event shall the Indemnitor be required to pay the fees and expenses of more than
one counsel employed by more than one Indemnified Party with respect to any
claim) and the Indemnitor shall not have the right to direct the defense of any
such action on behalf of the Indemnified Party. The Indemnitor shall have the
right, in its sole discretion, to settle any claim for monetary damages for
which indemnification has been sought and is available hereunder; provided,
however, that neither Indemnitor nor the Indemnified Party shall settle,
compromise or make any disposition of any claim under this Article IX which
would or may result in liability to the Indemnified Party or Indemnitor,
respectively, without the written consent of Indemnitee or Indemnitor,
respectively. No claim for indemnification under Section 9.1(a)(i) or Section
9.1(b) may be made more than one year after the Closing Date. No claim to
indemnification under Section 9.1(a)(iii) may be made more than three years
after the date of filing of Seller's 1998 United States federal income tax
return.

the meanings set forth below:

              (i)    "Participating Distributees" shall mean shareholders and

     Stock constituting the Purchase Price.

              (iii)  "Section 9.1(a)(ii) Obligations" means Seller's
     obligations arising under Section 9.1(a), only insofar as they arise under
     Section 9.1(a)(ii).

percent of the Purchase Consideration, Seller shall designate as "Participating

          (c) Prior to the distribution of any Purchase Consideration by Seller,
Seller shall cause each Participating Distributee to execute and deliver to
Buyer agreements, in form and substance reasonably satisfactory to Buyer,
providing for the assumption of Seller's Section 9.1(a)(ii) Obligations upon the
following terms and conditions:

              (i)    Each Participating Distributee shall be liable for Seller's
     Section 9.1(a)(ii) Obligations to the extent, and only to the extent, of
     the Purchase Consideration distributed to it by Seller.

              (ii)   A Participating Distributee shall constitute an
     "Indemnitor" under Section 9.3 and shall have all other rights of Seller

<PAGE>
 
     relate to the Section 9.1(a)(ii) Obligations for which such Participating
     Distributee is liable.

              (iii)  Such other terms and conditions as Seller, Buyer or the
     Participating Distributee may reasonably require in order to carry out the
     intent of this Section 9.4.

Nothing in this Section 9.4 is intended to, nor shall it be construed to, limit
in any respect Seller's indemnification obligations under this Agreement.

     11.1  Dispute Resolutions. Except with respect to injunctive relief,
neither party shall institute a proceeding in any court or administrative agency
to resolve a dispute between the parties before that party has sought to resolve
the dispute through direct negotiation with the other party. If the dispute is
not resolved within two weeks after a demand for direct negotiation, the parties
shall attempt to resolve the dispute through mediation. If the parties do not
promptly agree on a mediator, the parties shall request the Association of
Attorney Mediators in Harris County, Texas to appoint a mediator certified by
the Supreme Court of Texas. If the mediator is unable to facilitate a settlement
of the dispute within a reasonable period of time, as determined by the
mediator, the mediator shall issue a written statement to the parties to that
effect and any unresolved dispute or controversy arising under or in connection
with this Agreement shall be settled exclusively by arbitration, conducted
before a panel of three arbitrators in Houston, Texas, in accordance with the
rules of the American Arbitration Association then in effect, subject to the

                                       52
<PAGE>
 
provisions of this Article. Each party shall appoint one arbitrator from the
panels of arbitrators of the American Arbitration Association within thirty days
after the statement issued by the mediator and these two arbitrators shall
appoint a third arbitrator within ten days after their selection. The
arbitration shall commence within thirty days after all of the arbitrators have
been selected and shall conclude within thirty days thereafter. The arbitrators
shall render their decision within thirty days after the conclusion of the
arbitration. A decision by a majority of the arbitration panel shall be final
and binding. Judgment may be entered on the arbitrators' award in any court
having jurisdiction. The costs and expenses, including reasonable attorneys'
fees, of the prevailing party in any dispute arising under this Agreement will
be promptly paid by the other party.

                                FIRST AMENDMENT
                          TO STOCK PURCHASE AGREEMENT

     This First Amendment to Stock Purchase Agreement (the "First Amendment")
dated July 15, 1998, is by and among Elmagco, Inc., a Delaware corporation
("Elmagco"), Begemann, Inc., a Delaware corporation ("Seller"), and Boots &
Coots International Well Control, Inc., a Delaware corporation ("Buyer").

                              W I T N E S S T H:

     WHEREAS, Elmagco, Seller, and Buyer have entered into that certain Stock
Purchase Agreement dated June 22, 1998 (the "Purchase Agreement") pursuant to
which Buyer is purchasing from Seller all of the issued and outstanding stock of
Elmagco; and

     WHEREAS, Elmagco, Seller, and Buyer desire to amend the Purchase Agreement
as herein set forth.

     NOW THEREFORE, in consideration of the premises herein contained and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

     1.   Definitions.  Unless the context hereof indicates otherwise, all
capitalized terms used herein shall have the same meaning as such capitalized
terms are defined in the Purchase Agreement.

     2.   Amendment to Defend Terms.  The parties hereto agree that the term
"Subsidiaries" and "Subsidiary" as used in the Purchase Agreement shall be
defined to include the following entities, both collectively and individually:
(i) Baylor Electronics, Inc. a Texas corporation, (ii) Baylor Controls, Inc., a
Texas corporation, (iii) Baylor Company, a Texas corporation, (iv) Baylor
Limited, a United Kingdom corporation, and (v) Schottel, Inc., a Delaware
corporation.

     3.   Amendment to Section 3.3.  The parties hereto agree that Section 3.3
of the Purchase Agreement shall be amended and replaced in its entirety by the
following paragraph:

          "3.3 Capital of Elmagco.  The authorized capital stock of Elmagco
     consists of 2,000 shares of common stock, having a par value of $1.00 each,
     of which 100 shares are issued and outstanding and 1,000 shares of
     preferred stock, having a par value of $1.00 each, none of which are issued
     and outstanding.  All of the Shares are validly issued, fully paid and non-
     assessable.  There are no outstanding subscriptions, options, rights,
     warrants, convertible securities, or other agreements or commitments
     obligating Elmagco to issue or to transfer from treasury any additional
     shares of its capital stock of any class."

     4.   Amendment to Schedule 3.5.  The attached Schedule 3.5 is incorporated
herein 
<PAGE>
 
and made a part of this Agreement and part of the Purchase Agreement by this
reference. Effective July 15, 1998, the amended Schedule 3.5 shall supersede the
Schedule 3.5 that was attached to the Purchase Agreement on June 22, 1998.

     5.   Ratification.  The terms and provisions as set forth in this First
Amendment shall modify and supersede all inconsistent terms and provisions set
forth in the Purchase Agreement. Except as expressly modified and superseded by
this First Amendment, the terms and provisions of the Purchase Agreement and any
instruments executed in connection with the Purchase Agreement are hereby
ratified and confirmed and shall continue in full force and effect.  Except as
expressly modified and superseded by this First Amendment, each of the parties
hereto specifically ratifies all representations and warranties made in the
Purchase Agreement and certifies that the representations and warranties made
therein remain true and correct as if the representations and warranties were
made herein as of the date hereof.  Buyer hereby waives any and all claims with
respect to any representation or warranty made in Section 3.3 of the Purchase
Agreement, Section 3.5 of the Purchase Agreement or Schedule 3.5 attached to the
Purchase Agreement, to the extent such claim is based on a representation or
warranty that has been superseded by this First Amendment.

     6.   Extension.

          (a)  The parties hereto agree that the Closing shall take place at
               such time and date, no later than 5:00 p.m. Houston time on July
               23, 1998, as may be mutually agreed upon by Seller and Buyer, or,
               if Seller and Buyer do not otherwise so agree, at 10:00 a.m.
               Houston time on July 23, 1998.  Five o'clock p.m. Houston time,
               on July 23, 1998 is hereinafter referred to as the "New Closing
               Deadline."

          (b)  In consideration of Seller's agreement to extend the date of
               Closing beyond July 15, 1998, Buyer shall pay to Seller upon
               execution of this First Amendment by Elmagco, Buyer, and Seller
               the amount of $500,000.00 (the "Extension Fee") by wire transfer
               to Seller's counsel, Winstead Sechrest & Minick P.C. Buyer
               unconditionally and irrevocably authorizes Winstead Sechrest &
               Minick P.C. to disburse the Extension Fee to Seller. The
               Extension Fee is non-refundable, but shall be applied to the cash
               portion of the Purchase Price at Closing if Seller receives the
               cash portion of the Purchase Price prior to the New Closing
               Deadline (receipt by Seller of the cash portion of the Purchase
               Price is hereinafter referred to as "Funding").

          (c)  If Funding does not occur by the New Closing Deadline, Seller
               shall be entitled to: (i) terminate the Purchase Agreement and
               retain the Extension Fee; (ii) receive and recover from Buyer the
               breakup fee pursuant to, and subject to the conditions of,
               Section 2.3 of the Purchase Agreement, except that the parties
               hereto agree that such break up fee shall be reduced by the
               amount of the Extension Fee.
<PAGE>
 
          (d)  In addition to the foregoing, the Purchase Price and the cash
               portion thereof due at Closing shall be increased by $27,000,000,
               multiplied by Comerica Bank-Texas' base rate on July 15, 1998,
               divided by 365, multiplied by the number of days after July 15,
               1998 through and including the date on which Funding occurs.

     7.   Execution Counterparts.  This First Amendment may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original
and all of which taken together shall constitute but one and the same
instrument.

     8.   Governing Law.  This First Amendment shall be governed by and
construed in accordance with the internal laws of the State of Texas.

     9.   Successors and Assigns.  This First Amendment is binding upon and
shall inure to the benefit of Elmagco, Seller, Buyer, and their respective
successors and assigns.

     10.  Headings.  The headings, captions and arrangements used in this First
Amendment are for convenience only and shall not affect the interpretation of
this First Amendment.

     11.  NO ORAL AGREEMENTS.  THIS FIRST AMENDMENT, WHEN TAKEN TOGETHER WITH
THE PURCHASE AGREEMENT AND THE SCHEDULES THERETO, CONSTITUTE THE ENTIRE
AGREEMENT AMONG THE PARTIES CONCERNING THE SUBJECT MATTER HEREOF AND SUPERSEDES
ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER
WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE

                               SECOND AMENDMENT
                          TO STOCK PURCHASE AGREEMENT


     This Second Amendment to Stock Purchase Agreement (the "Second Amendment")
dated July  23, 1998, is by and among Elmagco, Inc., a Delaware corporation
("Elmagco"), Begemann, Inc., a Delaware corporation ("Seller"), and Boots &
Coots International Well Control, Inc., a Delaware corporation ("Buyer").

                              W I T N E S S T H:

     WHEREAS, Elmagco, Seller, and Buyer have entered into that certain Stock
Purchase Agreement dated June 22, 1998 (the "Purchase Agreement") pursuant to
which Buyer is purchasing from Seller all of the issued and outstanding stock of
Elmagco;

     WHEREAS,  Elmagco, Seller and Buyer have entered into that certain First
Amendment to Stock Purchase Agreement dated July 21, 1998 (the "First
Amendment"); and

     WHEREAS, Elmagco, Seller, and Buyer desire to further amend the Purchase
Agreement as herein set forth.

     NOW, THEREFORE, in consideration of the premises herein contained and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

     1.   Definitions.  Unless the context hereof indicates otherwise, all
capitalized terms used herein shall have the same meaning as such capitalized
terms are defined in the Purchase Agreement.

     2.   Amendment.  As of the Closing Date, Seller is entitled to receive from
Elmagco, as a dividend, a tax sharing payment for the period through the Closing
Date.  The amount of such tax sharing payment is hereby recognized and approved
as a dividend from Elmagco to Seller as of the Closing Date.  The amount of the
tax sharing payment, net of certain other balances between Elmagco and Seller
which are being offset as of the Closing Date, is herein referred to as the
"Additional Distribution."  Pursuant to Section 1.6 of the Purchase Agreement,
Seller is responsible for all franchise taxes of Elmagco resulting from the
Section 338(h)(10) election described therein (the "Resulting Franchise Taxes").
As of the date hereof, the amount of the Resulting Franchise Taxes is unknown.
Accordingly, Buyer and Seller hereby agree that Elmagco shall withhold from the
Additional Distribution, as security for Seller's obligation to pay the
Resulting Franchise Taxes, the sum of $600,000 (the "Withheld Tax Amount").
Seller hereby authorizes Buyer and Elmagco to utilize the Withheld Tax Amount to
pay the Resulting Franchise Taxes, which Seller agrees shall be paid pursuant to
a timely filed franchise tax return (or returns, if Resulting Franchise Taxes
are due to more than one state).  If the Resulting Franchise Taxes exceed the
Withheld Tax Amount, Buyer and Elmagco will promptly notify Seller, and Seller
will wire transfer to Elmagco the balance of the Resulting Franchise Taxes.  If
the Withheld Tax Amount exceeds the Resulting Franchise Taxes reflected on such
return or returns, Buyer and Elmagco shall immediately release the excess to
Seller.
<PAGE>
 
     3.   Ratification.  The terms and provisions as set forth in this Second
Amendment shall modify and supersede all inconsistent terms and provisions set
forth in the Purchase Agreement as amended. Except as expressly modified and
superseded by this Second Amendment, the terms and provisions of the Purchase
Agreement, as amended and any instruments executed in connection with the
Purchase Agreement, as amended are hereby ratified and confirmed and shall
continue in full force and effect.  Each of the parties hereto specifically
ratifies all representations and warranties made in the Purchase Agreement, as
amended and certifies that the representations and warranties made therein
remain true and correct as if the representations and warranties were made
herein as of the date hereof.

     4.   Execution Counterparts.  This Second Amendment may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original
and of which taken together shall constitute but one and the same instrument.

     5.   Governing Law.  This Second Amendment shall be governed by and
construed in accordance with the internal laws of the State of Texas.

     6.   Successors and Assigns.  This Second Amendment is binding upon and
shall inure to the benefit of Elmagco, Seller, Buyer, and their respective
successors and assigns.

     7.   Headings.  The headings, captions and arrangements used in this Second
Amendment are for convenience only and shall not affect the interpretation of
this Second Amendment.

     8.   NO ORAL AGREEMENTS.  THIS SECOND AMENDMENT, WHEN TAKEN THERETO
TOGETHER WITH THE PURCHASE AGREEMENT AND THE FIRST AMENDMENT AND THE SCHEDULES
CONSTITUTES THE ENTIRE AGREEMENT AMONG THE PARTIES CONCERNING THE SUBJECT MATTER
HEREOF AND SUPERSEDES ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND

computation of such payment; provided, however, that, if such extension would
cause payment of interest on or principal of Advances to be made in the next
following calendar month, such payment shall be made on the next preceding
Business Day.

      SECTION 2.09.  TAXES.  (a) Any and all payments by the Borrower hereunder
or under the Notes shall be made, in accordance with Section 2.08, free and
clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding, in the case of each Lender, net income taxes that are
imposed by the United States and franchise taxes and net income taxes that are
imposed on such Lender by the state or foreign jurisdiction under the laws of
which such Lender is organized or any political subdivision thereof and, in the
case of each Lender, franchise taxes and net income taxes that are imposed on
such Lender by the state or foreign jurisdiction of such Lender's Applicable
Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "TAXES").  If the Borrower shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder or under any
Note to any Lender, (i) the sum payable shall be increased as may be necessary
so that after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.09) such Lender receives an amount
equal to the sum it would have received had no such deductions been made, (ii)
the Borrower shall make such deductions and (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

          (b) In addition, the Borrower shall pay any present or future stamp,
documentary, excise, property or similar taxes, charges or levies that arise
from any payment made hereunder or under the Notes or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or
under the other Loan Documents (hereinafter referred to as "OTHER TAXES").

          (c) The Borrower shall indemnify each Lender for the full amount of
Taxes and Other Taxes, and for the full amount of taxes imposed by any
jurisdiction on amounts payable under this Section 2.09, paid by such Lender and
any liability (including penalties, additions to tax, interest and expenses)
arising therefrom or with respect thereto. This indemnification shall be made
within 30 days from the date such Lender makes written demand therefor.

          (d) Within 30 days after the date of any payment of Taxes, the
Borrower shall furnish to each Lender, at its address referred to in Section
7.02, the original receipt of payment thereof or a certified copy of such
receipt.  In the case of any payment hereunder or under the Notes by the
Borrower through an account or branch outside the United States or on behalf of
the Borrower by a payor that is not a United States person, if the Borrower
determines that no Taxes are payable in respect thereof, the Borrower shall
furnish, or shall cause such payor to furnish, to each Lender, at such address,
an opinion of counsel acceptable to Prudential stating that such payment is
exempt from Taxes.  For purposes of this subsection (d) and subsection (e), the
terms 

                                       18
<PAGE>
 
"UNITED STATES" and "UNITED STATES PERSON" shall have the meanings specified in
Section 7701 of the Internal Revenue Code.

          (e) Each Lender organized under the laws of a jurisdiction outside the
United States shall, on or prior to the date of its execution and delivery of
this Agreement in the case of Prudential, and on the date on which it became a
Lender, in the case of each other Lender, and from time to time thereafter if
requested in writing by the Borrower (but only so long thereafter as such Lender
remains lawfully able to do so), provide the Borrower with Internal Revenue
Service form 1001 or 4224, as appropriate, or any successor form prescribed by
the Internal Revenue Service, certifying that such Lender is entitled to
benefits under an income tax treaty to which the United States is a party that
reduces the rate of withholding tax on payments under this Agreement or the
Notes or certifying that the income receivable pursuant to this Agreement or the
Notes is effectively connected with the conduct of a trade or business in the
United States.  If the form provided by a Lender at the time such Lender first
becomes a party to this Agreement indicates a United States interest withholding
tax rate in excess of zero, withholding tax at such rate shall be considered
excluded from Taxes unless and until such Lender provides the appropriate form
certifying that a lesser rate applies, whereupon withholding tax at such lesser
rate only shall be considered excluded from Taxes for periods governed by such
form; provided, however, that, if at the date on which a Lender assignee becomes
a party to this Agreement, the Lender assignor was entitled to payments under
subsection (a) in respect of United States withholding tax with respect to
interest paid at such date, then, to such extent, the term Taxes shall include
(in addition to withholding taxes that may be imposed in the future or other
amounts otherwise includable in Taxes) United States withholding tax, if any,
applicable with respect to the Lender assignee on such date.  If any form or
document referred to in this subsection (e) requires the disclosure of
information, other than information necessary to compute the tax payable and
information required on the date hereof by Internal Revenue Service form 1001 or
4224, that the Lender reasonably considers to be confidential, the Lender shall
give notice thereof to the Borrower and shall not be obligated to include in
such form or document such confidential information; provided, however, that the
Borrower shall have no obligation to "gross-up" under subsection (a) (with
respect to the Lender contemplated by clauses (x) - (z) below) in any case where
(x) the Lender is a person other than the Lender originally named herein and (y)
at the time the new Lender acquires, through assignment or otherwise, an
interest in the Advance, the Lender is unable to deliver either a Form 1001 or a
Form 4224 to the Borrower and (z) the assignor of such interest or other person
from whom the new Lender acquired its interest was, at such time of such
assignment or other transfer, able to deliver such forms.

          (f) For any period with respect to which a Lender has failed to
provide the Borrower with the appropriate form described in subsection (e)
(other than if such failure is due to a change in law occurring after the date
on which a form originally was required to be provided or if such form otherwise
is not required under subsection (e)), such Lender shall not be entitled to
indemnification under subsection (a) or (c) with respect to Taxes imposed by the
United States; provided, however, that should a Lender become subject to Taxes
because of its failure to deliver 

                                       19
<PAGE>
 
a form required hereunder, the Borrower shall take such steps as such Lender
shall reasonably request to assist such Lender to recover such Taxes.

          (g) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 2.09 shall survive the payment in full of principal and interest
hereunder and under the Notes.

      SECTION 2.10.  SHARING OF PAYMENTS, ETC.  If any Lender shall obtain at
any time any payment (whether voluntary, involuntary, through the exercise of
any right of set-off, or otherwise) (a) on account of Obligations due and
payable to such Lender hereunder and under the other Loan Documents at such time
in excess of its ratable share (according to the proportion of (i) the amount of
such Obligations due and payable to such Lender at such time to (ii) the
aggregate amount of the Obligations due and payable to all Lenders hereunder and
under the other Loan Documents at such time) of payments on account of the
Obligations due and payable to all Lenders hereunder and under the other Loan
Documents at such time obtained by all the Lenders at such time or (b) on
account of Obligations owing (but not due and payable) to such Lender hereunder
and under the other Loan Documents at such time in excess of its ratable share
(according to the proportion of (i) the amount of such Obligations owing to such
Lender at such time to (ii) the aggregate amount of the Obligations owing (but
not due and payable) to all Lenders hereunder and under the other Loan Documents
at such time) of payments on account of the Obligations owing (but not due and
payable) to all Lenders hereunder and under the other Loan Documents at such
time obtained by all the Lenders at such time, such Lender shall forthwith
purchase from the other Lenders such participations in the Obligations due and
payable or owing to them, as the case may be, as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each of them;
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each other
Lender shall be rescinded and such other Lender shall repay to the purchasing
Lender the purchase price to the extent of such other Lender's ratable share
(according to the proportion of (i) the purchase price paid to such Lender to
(ii) the aggregate purchase price paid to all lenders) of such recovery together
with an amount equal to such Lender's ratable share (according to the proportion
of (i) the amount of such other Lender's required repayment to (ii) the total
amount so recovered from the purchasing Lender) of any interest or other amount
paid or payable by the purchasing Lender in respect of the total amount so
recovered.  The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to this Section 2.10 may, to the fullest extent
permitted by law, exercise all of its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of the Borrower in the amount of such participation.

      SECTION 2.11.  USE OF PROCEEDS.  The proceeds of the Advances shall be
available (and the Borrower agrees that it shall use such proceeds) (i) to repay
all amounts due and payable under the Promissory Note dated July 31, 1997, made
by IWC Services, Inc., a Texas corporation ("IWC SERVICES") in the face amount
of $2,066,597 and approximately $300,000 owed to LaSalle Cattle Company, Ltd.
pursuant to a Stock Purchase Agreement dated December 1997 between the 

                                       20
<PAGE>
 
Borrower and LaSalle Cattle Company, Ltd., pursuant to which the Company
acquired all of the stock of ITS Supply Corporation and (ii) for working capital
purposes (but only to the extent of any excess over the amounts paid under
clause (i) of this Section 2.11).

     structure or capitalization.

          (b) No Material Adverse Change shall have occurred since March 31,
     1998, and no material inaccuracy in the financial statements prepared as of

     Section 3.01 shall exist.

          (c) Since March 31, 1998, the Borrower shall not have incurred any

     or otherwise, except as disclosed to the Lenders in the most recent
     Consolidated financial statements of the Borrower and its Subsidiaries, and
     the footnotes thereto, and except for liabilities or obligations incurred
     by the Borrower and its Subsidiaries taken as a whole in the ordinary
     course of business or which are not material to the Borrower and its
     Subsidiaries taken as a whole or as otherwise disclosed in Schedule 3.01(c)

     liabilities except those set forth in such financial statements or
     disclosed in the footnotes thereto.

          (d) Prior to the Closing Date, each of the Lenders shall have received

     Advances).

     lead them to believe that any disclosure made to them by the Borrower or
     any Subsidiary or other Affiliate thereof was or has become misleading,
     incorrect or incomplete in any material respect; without limiting the
     generality of the foregoing, the Lenders shall have been given such access
     to the management, records, books of account, contracts and properties of
     the Borrower, its Subsidiaries and other Affiliates as they shall have
     requested.

     (ii) is duly qualified and in good standing as a foreign corporation in
     each other jurisdiction in which the conduct of its business or ownership
     of property requires it to so qualify except where the failure to so
     qualify could not reasonably be expected to have a Material Adverse Effect
     and 

                                       24
<PAGE>
 
     (iii) has all requisite corporate power and authority to own or lease and

          (b) Set forth on Schedule 4.01(b) hereto is a complete and accurate
     list of all Subsidiaries of the Borrower, showing as of the date hereof (as
     to each such Subsidiary) the jurisdiction of its incorporation, the number
     of shares of each class of capital stock authorized, and the number
     outstanding, on the date hereof and the percentage of the outstanding
     shares of each such class owned (directly or indirectly) by the Borrower.
     Each such Subsidiary (i) is a corporation duly organized, validly existing
     and in good standing under the laws of the jurisdiction of its
     incorporation, (ii) is duly qualified and in good standing as a foreign
     corporation in each other jurisdiction in which the conduct of its business

     corporate powers, have been duly authorized by all necessary corporate
     action, and do not (i) contravene the Borrower's certificate of
     incorporation or bylaws, (ii) violate any law (including, without
     limitation, the Exchange Act and the Racketeer Influenced and Corrupt

     their properties or (iv) result in or require the creation or imposition of
     any Lien upon or with respect to any of the properties of the Borrower or
     any of its Subsidiaries.  Neither the Borrower nor any of its Subsidiaries
     is in violation of any such law, rule, regulation, order, writ, judgment,
     injunction, decree, determination or award or in breach of any such
     contract, loan agreement, indenture, mortgage, deed of trust, lease or
     other instrument, the violation or breach of which is reasonably likely to
     have a Material Adverse Effect.

          (d) No authorization or approval or other action by, and no notice to
     or filing with, any governmental authority or regulatory body or any other
     third party is required for (i) the due execution, delivery or performance
     by the Borrower of this Agreement, the Notes or any other Loan Document, or
     (ii) to the best knowledge of the Borrower, the exercise by any Lender of
     its rights under the Loan Documents.

          (e) This Agreement has been, and each of the Notes and each other Loan
     Document when delivered hereunder will have been, duly executed and
     delivered by the 

                                       25
<PAGE>
 
     Loan Party thereto. This Agreement is, and each of the Notes and each other
     Loan Document when delivered hereunder will be, the legal, valid and
     binding obligation of the Loan Party thereto, enforceable against such Loan
     Party in accordance with its terms.

          (f) The Consolidated financial statements of the Borrower and its
     Subsidiaries for and as of the end of the year ended June 30, 1997,

     accountants, copies of which have been furnished to each Lender, fairly
     present, the Consolidated financial condition of the Borrower and its
     Subsidiaries for the period ended on such date, all in accordance with GAAP
     applied on a consistent basis, and since March 31, 1998, there has been no
     Material Adverse Change.

          (g) The Borrower is, individually and together with its Subsidiaries,
     Solvent.

          (h) All written information, reports and other papers and data
     furnished to the Lenders by, on behalf of, or at the direction of the
     Borrower or any other Loan Party were, at the time the same were so
     furnished, complete and correct in all material respects, to the extent
     necessary to give the recipient true and accurate knowledge of the subject
     matter, or in the case of financial statements, present fairly, in
     accordance with GAAP consistently applied, the financial position of the
     Persons involved as at the date thereof and the results of operations for
     such periods.  Neither the Loan Documents nor any of the schedules,
     attachments, written statements, documents, certificates or other items
     prepared or supplied to the Lenders by or on behalf of the Borrower with

     terminated, within the meaning of Title IV of ERISA.

          (p) Neither the business nor the properties of the Borrower or any of
     its Subsidiaries are affected by any fire, explosion, accident, strike,
     lockout or other labor dispute, drought, storm, hail, earthquake, embargo,

     Effect.

          (q) The operations and properties of the Borrower and each of its
     Subsidiaries comply in all material respects with all Environmental Laws,
     all necessary Environmental Permits have been obtained and are in effect
     for the operations and properties of the Borrower and its Subsidiaries, the
     Borrower and its Subsidiaries are in compliance in all material respects
     with all such Environmental Permits, and no circumstances exist that would
     be reasonably likely to (i) form the basis of an Environmental Action
     against the Borrower or any of its Subsidiaries or any of their properties
     that could have a Material Adverse Effect or (ii) cause any such property
     to be subject to any restrictions on ownership, occupancy, use or
     transferability under any Environmental Law.

     material respects with all Environmental Laws and Environmental Permits.

          (s) None of the Borrower or any of its Subsidiaries is in violation of
     its respective organizational documents or in default in the performance or
     observance of any obligation, agreement, covenant or condition contained in
     any contract, indenture, mortgage, deed of trust, loan or credit agreement,
     note, lease or other agreement or instrument to which the Borrower or any
     such Subsidiary is a party or by which the Borrower or any such Subsidiary
     may be bound or to which any of the property or assets of the Borrower or
     any such Subsidiary is subject, except for such violations or defaults that
     could not result in a Material Adverse Effect.

          (t) The Borrower and each of its Subsidiaries has filed, has caused to
     be filed or has been included in all tax returns (Federal, state, local and

     underwriter" for, an "investment company," as such terms are defined in the
     Investment Company Act of 1940, as amended. Neither the making of any
     Advances nor the application of the proceeds or repayment thereof by the
     Borrower, nor the consummation of the other transactions contemplated
     hereby, will violate any provision of such Act or any rule, regulation or
     order of the Securities and Exchange Commission thereunder.

          (v) Neither the Borrower nor any of its Subsidiaries is a "holding
     company", or a "subsidiary company" of a "holding company" or an

     "holding company", as such terms are defined in the Public Utility Holding
     Company Act of 1935, as amended.

          (w) Each of the Borrower and its Subsidiaries has good and valid title
     in fee simple to all real property, and title to all personal property,

     Subsidiaries to conduct, all transactions otherwise permitted under the

     and the Insufficiency of any and all other Plans of the Borrower and its
     ERISA Affiliates with respect to which an ERISA Event shall have occurred
     and then exist (or the liability of the Borrower and its ERISA Affiliates
     related to such ERISA Event) exceeds $100,000; or

          (k) the Borrower or any of its ERISA Affiliates shall have been
     notified by the sponsor of a Multiemployer Plan that it has incurred
     Withdrawal Liability to such Multiemployer Plan in an amount that, when
     aggregated with all other amounts required to be paid to Multiemployer

     notified by the sponsor of a Multiemployer Plan of the Borrower or any of
     its ERISA Affiliates that such Multiemployer Plan is in reorganization or

     result of such reorganization or termination the aggregate annual
     contributions of the Borrower and its ERISA Affiliates to all Multiemployer
     Plans that are then in reorganization or being terminated have been or will
     be increased over the amounts contributed to such Multiemployer Plans for
     the plan years of such Multiemployer Plans immediately preceding the plan

payable, without presentment, demand, protest or further notice of any kind, all
of which are hereby expressly waived by the Borrower; provided, however, that
upon the occurrence of an Event of Default pursuant to the terms of subsection

shall automatically be terminated and (y) the Notes, all such interest and all
such amounts shall automatically become and be due and payable, without

      SECTION 7.03.  NO WAIVER; REMEDIES.  No failure on the part of any Lender,
and no delay in exercising, any right under any Loan Document shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right

right.  The remedies provided under any Loan Document are cumulative and not
exclusive of any remedies provided by law.

      SECTION 7.04.  COSTS AND EXPENSES; INDEMNIFICATION.  (a) The Borrower
agrees to pay on demand (i) all reasonable costs and expenses of the Lenders in
connection with the modification, amendment and syndication of the Loan
Documents (including, without limitation, the reasonable fees and expenses of
counsel for Prudential with respect thereto, with respect to advising the
Lenders as to its rights and responsibilities, or the perfection, protection or
preservation of rights or interests, under the Loan Documents, with respect to
negotiations with the Borrower or with other creditors of the Borrower or any of
its Subsidiaries arising out of any Default or any events of circumstances that
may give rise to a Default and with respect to presenting claims in or otherwise
participating in or monitoring any bankruptcy, insolvency or other similar
proceedings involving creditors' rights generally and any proceeding ancillary
thereto) and (ii) all costs and expenses of the Lenders in connection with the
enforcement of the Loan Documents, whether in any action, suit or litigation,
any bankruptcy, insolvency or other similar proceeding affecting creditors'
rights generally or otherwise (including, without limitation, the reasonable
fees and expenses of counsel for each Lender with respect thereto).

          (b)  (i)  The Borrower agrees that it will indemnify and hold harmless
     the Lenders to the fullest extent permitted by law, from and against any
     and all losses, claims, damages, obligations, penalties, judgments, awards,
     liabilities, costs, expenses and 

                                       40
<PAGE>
 
     disbursements (and any and all actions, suits, proceedings and
     investigations in respect thereof and any and all legal or other costs,
     expenses and disbursements in giving testimony or furnishing documents in
     response to a subpoena or otherwise), including, without limitation, the
     costs, expenses and disbursements, as and when incurred, of investigating,
     preparing or defending any such action, proceeding or investigation
     (whether or not in connection with litigation in which any of the Lenders
     is a party thereto), directly or indirectly, caused by, relating to, based
     upon, arising out of or in connection with (a) this Agreement and the other
     Loan Documents, or (b) any untrue statement or alleged untrue statement of
     a material fact contained in, or omissions or alleged omissions from any
     filing with any governmental agency or similar statements or omissions in
     or from any information furnished by the Borrower or any of its
     Subsidiaries or Affiliates to any of the Lenders or any other person in
     connection with this Agreement and the other Loan Documents; provided,
     however, that such indemnity agreement shall not apply to any such loss,
     claim, damage, obligation, penalty, judgment, award, liability, cost,
     expense or disbursement to the extent it is found in a final judgment by a
     court of competent jurisdiction (not subject to further appeal) to have
     resulted primarily and directly from the gross negligence or willful
     misconduct of any of the Lenders. The Borrower also agrees that the Lenders
     shall have no liability (whether direct or indirect, in contract or tort or
     otherwise) to the Borrower for or in connection with this Agreement and the
     other Loan Documents or the transactions contemplated thereby, except for
     any such losses, claims, damages, obligations, penalties, judgments,
     awards, liabilities, costs, expenses and disbursements that are finally
     judicially determined by a court of competent jurisdiction (not subject to
     further appeal) to have resulted from the bad faith or gross negligence of
     any of the Lenders.

          (ii) The indemnification provisions in this Section shall be in
     addition to any liability which the Borrower may have to the Lenders or the
     Persons indemnified below in this sentence and shall extend to the
     following: the Lenders, Prudential, their respective affiliated entities,
     directors, officers, employees, legal counsel, agents and controlling
     persons (within the meaning of the federal securities laws), and none of
     such indemnified persons shall be liable for any act or omission of any of
     the others. All references to "Lender(s)" in these indemnification
     provisions shall be understood to include any and all of the foregoing.

          (iii)  If any action, suit, proceeding or investigation is commenced,
     as to which any indemnified party proposes to demand indemnification, it
     shall notify the Borrower with reasonable promptness; provided, however,
     that any failure by any indemnified party to so notify the Borrower shall
     not relieve the Borrower from its obligations hereunder. Prudential, on
     behalf of the Lenders, shall have the right to retain counsel of its choice
     to represent the Lenders, and the Borrower shall pay the reasonable fees,
     expenses and disbursements of such counsel; and such counsel shall, to the
     extent consistent with its professional responsibilities, cooperate with
     the Borrower and any counsel designated by the Borrower.  The Borrower
     shall be liable for any settlement of any claim against any 

                                       41
<PAGE>
 
     of the Lenders made with the Borrower's written consent, which consent
     shall not be unreasonably withheld. The Borrower shall not, without the
     prior written consent of Prudential, settle or compromise any claim, or
     permit a default or consent to the entry of any judgment in respect
     thereof, unless such settlement, compromise or consent includes, as an
     unconditional term thereof, the giving by the claimant to each of the
     Lenders of an unconditional and irrevocable release from all liability in
     respect of such claim.

          (iv) In order to provide for just and equitable contribution, if a
     claim for indemnification pursuant to the indemnification provisions
     contained in this Section is made but is found in a final judgment by a
     court of competent jurisdiction (not subject to further appeal) that such
     indemnification may not be enforced in such case, even though the express
     provisions hereof provide for indemnification in such case, then the
     Borrower, on the one hand, and the Lenders, on the other hand, shall
     contribute to the losses, claims, damages, obligations, penalties,
     judgments, awards, liabilities, costs, expenses and disbursements to which
     the indemnified persons may be subject in accordance with the relative
     benefits received by the Borrower, on the one hand, and the Lenders, on the
     other hand, and also the relative fault of the Borrower, on the one hand,
     and the Lenders, on the other hand, in connection with the statements, acts
     or omissions which resulted in such losses, claims, damages, obligations,
     penalties, judgments, awards, liabilities, costs, expenses and
     disbursements and the relevant equitable considerations shall also be
     considered.  No person found liable for a fraudulent misrepresentation
     shall be entitled to contribution from any person who is not also found
     liable for such fraudulent misrepresentation.

          (v) Neither termination of the Commitments nor repayment of the
     Advances shall affect the indemnification provisions contained in this
     Section which shall then remain operative and in full force and effect.

          (c) If any payment of principal of any Advance is made by the Borrower
to or for the account of a Lender other than on the last day of the Interest
Period for such Advance, as a result of a payment or conversion pursuant to
Section 2.07(c), acceleration of the maturity of the Notes pursuant to Section
6.01 or for any other reason, the Borrower shall, upon demand by such Lender,
pay to such Lender any amounts required to compensate such Lender for any
additional losses, costs or expenses that it may reasonably incur as a result of
such payment, including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender to fund or
maintain such Advance.

          (d) If the Borrower fails to pay when due any costs, expenses or other
amounts payable by it under any Loan Document, including, without limitation,
fees and expenses of counsel and indemnities, such amount may be paid on behalf
of the Borrower by any Lender, in its sole discretion.

      SECTION 7.05.  RIGHT OF SET-OFF.  Upon (a) the occurrence and during the
continuance of any Event of Default and (b) the making of the request or the
granting of the consent specified by Section 6.01 to authorize Prudential to
declare the Notes due and payable pursuant to the provisions of Section 6.01,
each Lender is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and otherwise apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender to or for the
credit or the account of the Borrower against any and all of the Obligations of
the Borrower now or hereafter existing under this Agreement and the Note or
Notes held by such Lender, irrespective of whether such Lender shall have made
any demand under this Agreement or such Note or Notes and although such
obligations may be unmatured.  Each Lender agrees promptly to notify the
Borrower after any such set-off and application; provided, however, that the
failure to give such notice shall not affect the validity of such set-off and
application.  The rights of each Lender under this Section are in addition to
other rights and remedies (including, without limitation, other rights of set-
off) that such Lender may have.

      SECTION 7.06.  BINDING EFFECT.  This Agreement shall become effective when
it shall have been executed by the Borrower and Prudential and thereafter shall
be binding upon and inure to the benefit of the Borrower, Prudential and each
Lender party thereto from time to time and their respective successors and
assigns, except that the Borrower shall not have the right to assign its rights
hereunder or any interest herein without the prior written consent of the
Lenders.

      SECTION 7.07.  ASSIGNMENTS AND PARTICIPATIONS.  (a) Each Lender may assign
to one or more banks or other entities all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment or Commitments and the Advances owing to it and the
Note or Notes held by it.

     (b) Prudential shall maintain at its address referred to in Section 7.02 a
register for the recordation of the names and addresses of the Lenders and the
Commitment of, and principal amount of the Advances owing under the Facility to,
each Lender from time to time (the "REGISTER").  The entries in the Register
shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower and the Lenders may treat each Person whose name is recorded in the
Register as a Lender hereunder for all purposes of this Agreement.  The Register
shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

     (c) The Borrower hereby agrees to cooperate with the Lenders in connection
with the assignment of the Commitments and Advances under Section 7.07(a).
Within five Business Days after its receipt of notice, the Borrower, at its own
expense, shall execute and deliver to the applicable Lender in exchange for the
surrendered Note or Notes a new Note to the order of such Lender's assignee in
an amount equal to the Commitment assumed by it and, if the assigning Lender has
retained a Commitment hereunder, a new Note to the order of the assigning Lender
in an amount equal to the Commitment retained by it hereunder.  Such new Note or
Notes shall 

                                       43
<PAGE>
 
be in an aggregate principal amount equal to the aggregate principal amount of
such surrendered Note or Notes, shall be dated the effective date of such
assignment.

     (d) Each Lender may sell participations in or to all or a portion of its
rights and obligations under this Agreement (including, without limitation, all

     the foregoing clause (ii) shall be an offer to prepay, in accordance with

     held by each holder (in this case only, "holder" in respect of any Note
     registered in the name of a nominee for a disclosed beneficial owner shall
     mean such beneficial owner) on a date specified in such offer (the
     "PROPOSED PREPAYMENT DATE"). Such Proposed Prepayment Date shall be not
     less than 30 days and not more than 60 days after the date of such offer
     (if the Proposed Prepayment Date shall not be specified in such offer, the

     delivered to the Company at least five days prior to the Proposed
     Prepayment Date.  A failure by a holder of Notes to respond to an offer to

     amount, together with interest on such Notes accrued to the date of
     prepayment.  On the Business Day preceding the date of prepayment, the

     and setting forth the details of the computation of such amount.  The

     prepayment of Notes pursuant to this paragraph 4C, the principal amount of
     the required prepayment of the Notes becoming due under paragraph 4A on or
     after the date of such prepayment shall be reduced in the same proportion
     as the aggregate unpaid principal amount of Notes is reduced as a result of
     such prepayment.

          (vi) Officer's Certificate.  Each offer to prepay the Notes pursuant
     to this paragraph 4C shall be accompanied by a certificate, executed by a

     were the date of the prepayment) and the details of such calculation; (e)
     the interest that would be due on each Note offered to be prepaid, accrued
     to the Proposed Prepayment Date; (f) that the conditions of this paragraph
     4C have been fulfilled; and (g) in reasonable detail, the nature and date
     of the Change in Control.

Notes prepaid or otherwise retired or purchased or otherwise acquired by the
Company or any of its Subsidiaries or Affiliates other than by prepayment

of prepayment made pursuant to paragraph 4C in proportion to the respective

any of its Subsidiaries or Affiliates to, prepay or otherwise retire in whole or
in part prior to their stated final maturity (other than by prepayment pursuant

to paragraph 8A), or purchase or otherwise acquire, directly or indirectly,
Notes held by any holder unless the Company or such Subsidiary or Affiliate
shall have offered to prepay or otherwise retire or purchase or otherwise
acquire, as the case may be, the same proportion of the aggregate principal
amount of Notes held by each other holder of Notes at the time outstanding upon
the same terms and conditions.  Any Notes so prepaid or otherwise retired or
purchased or otherwise acquired by the Company or any of its Subsidiaries or
Affiliates shall not be deemed to be outstanding for any purpose under this
Agreement, except as provided in paragraph 4D.

     property, stock or obligations to the holders of the Notes is authorized by
     an order or decree giving effect, and stating in such order or decree that
     effect is given, to the subordination of the Notes to Senior Debt, and made
     in a reorganization proceeding under any applicable bankruptcy or
     reorganization law, no payment or delivery by the Company of such cash,
     property, stock or obligations payable or deliverable with respect to the
     Notes shall be made to the holders of Senior Debt; and

     under any single instrument when the same becomes due and payable, whether
     at maturity or at a date fixed for prepayment or by declaration of
     acceleration or otherwise, then, unless and until the date on which such
     default shall have been remedied by payment in full or waived, no holder of
     the Notes shall accept or receive any direct or indirect payment of or on
     account of any indebtedness in respect of the Notes.

          (iv) Upon the occurrence and during the continuance of any Default
     Subordination Event (other than under circumstances when the terms of

     have been due and payable on any date during such Stand-Still Period, the
     provisions of this subparagraph (iv) shall not prevent such payment on or
     after the date immediately following the termination of such Stand-Still
     Period.

          (v) If any payment or distribution of any character, whether in cash,
     securities or other property, shall be received by any holder of Notes in
     contravention of any of the terms of this paragraph 7 and before all the

surrender of the Note to be exchanged at the principal office of the Company.
Whenever any Notes are so surrendered for exchange, the Company shall, at its

neither gain nor loss of interest shall result from any such transfer or
exchange.  Upon receipt of written notice from the holder of any Note of the
loss, theft, destruction or mutilation of such Note and, in the case of any such
loss, theft or destruction, upon receipt of such holder's unsecured indemnity
agreement, or in the case of any such mutilation upon surrender and cancellation
of such Note, the Company will make and deliver a new Note, of like tenor, in
lieu of the lost, stolen, destroyed or mutilated Note.

  12E.        PERSONS DEEMED OWNERS; PARTICIPATIONS.  Prior to due presentment
for registration of transfer, the Company may treat the Person in whose name any
Note is registered as the owner and holder of such Note for the purpose of
receiving payment of principal of and interest on such Note and for all other
purposes whatsoever, whether or not such Note shall be overdue, and the Company
shall not be affected by notice to the contrary.  Subject to the preceding
sentence, the holder of any Note may from time to time grant participations in
such Note to any Person on such terms and conditions as may be determined by
such holder in its sole and absolute discretion, provided that any such
participation shall be in a principal amount of at least $100,000.

  12F.        SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.  All
representa tions and warranties contained herein or in the other Subordinated

execution and delivery of this Agreement, the Notes, the Warrants and the other
Subordinated Note Documents, the transfer by you of any Note or Warrant or
portion thereof or interest therein and the payment of any Note, and may be
relied upon by any Transferee, regardless of any investigation made at any time
by or on behalf of you or any Transferee.  Subject to the preceding sentence,
this Agreement, the Notes, the Warrants and the other Subordinated Note
Documents embody the entire agreement and understanding between you and the
Company and supersede all prior agreements and understandings relating to the
subject matter hereof.

  12M.        WAIVER OF JURY TRIAL; CONSENT TO JURISDICTION.

          (I) THE COMPANY AND EACH HOLDER OF SECURITIES HEREBY KNOWINGLY,

     OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT, THE NOTES, THE WARRANTS OR
     THE OTHER SUBORDINATED NOTE DOCUMENTS, OR ANY TRANSACTIONS RELATING HERETO
     OR THERETO, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
     (WHETHER ORAL OR WRITTEN), OR ACTIONS OF THE COMPANY, THE HOLDERS OF THE
     SECURITIES OR THE COLLATERAL AGENT.  THE COMPANY ACKNOWLEDGES THAT THIS
     PROVISION IS A MATERIAL INDUCEMENT FOR  YOU TO ENTER INTO THIS AGREEMENT.

          (II) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT,
     THE NOTES, THE WARRANTS, THE OTHER SUBORDINATED NOTE DOCUMENTS OR ANY

     NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS.  THE COMPANY AND EACH
     HOLDER OF SECURITIES HEREBY IRREVOCABLY WAIVES ANY OBJECTIONS, INCLUDING,

<PAGE>
 
     THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE
     JURISDICTIONS.

  12N.        SEVERABILITY.  Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

  12O.        DESCRIPTIVE HEADINGS.  The descriptive headings of the several
paragraphs of this Agreement are inserted for convenience only and do not
constitute a part of this Agreement.

  12P.        MAXIMUM INTEREST PAYABLE.  The Company, you and all other holders
of the Notes specifically intend and agree to limit contractually the amount of
interest payable under this Agreement, the Notes and all other instruments and
agreements related hereto and thereto to the maximum amount of interest lawfully
permitted to be charged under applicable law.  Therefore, none of the terms of
this Agreement, the Notes or any instrument pertaining to or relating to this
Agreement or the Notes shall ever be construed to create a contract to pay
interest at a rate in excess of the maximum rate permitted to be charged under
applicable law, and neither the Company, any guarantor nor any other party
liable or to become liable hereunder, under the Notes, any guaranty or under any
other instruments and agreements related hereto and thereto shall ever be liable
for interest in excess of the amount determined at such maximum rate, and the
provisions of this paragraph 12P shall control over all other provisions of this
Agreement, any Notes, any guaranty or any other instrument pertaining to or
relating to the transactions herein contemplated.  If any amount of interest
taken or received by you or any holder of a Note shall be in excess of said
maximum amount of interest which, under applicable law, could lawfully have been
collected by you or such holder incident to such transactions, then such excess
shall be deemed to have been the result of a mathematical error by all parties
hereto and shall be refunded promptly by the Person receiving such amount to the
party paying such amount, or, at the option of the recipient, credited ratably
against the unpaid principal amount of the Note or Notes held by you or such
holder, respectively.  All amounts paid or agreed to be paid in connection with
such transactions which would under applicable law be deemed "interest" shall,
to the extent permitted by such applicable law, be amortized, prorated,
allocated and spread throughout the stated term of this Agreement and the Notes.
"APPLICABLE LAW" as used in this paragraph means that law in effect from time to
time which permits the charging and collection of the highest permissible
lawful, nonusurious rate of interest on the transactions herein contemplated
including laws of the State of New York and of the United States of America, and
"MAXIMUM RATE" as used in this paragraph means, with respect to each of the
Notes, the maximum lawful, nonusurious rates of interest (if any) which under
applicable law may be charged to the Company from time to time with respect to
such Notes.

  12Q.        COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall be an original but all of which together shall
constitute one instrument.

     FOR VALUE RECEIVED, the undersigned, BOOTS & COOTS INTERNATIONAL WELL
CONTROL, INC. (the "COMPANY"), a corporation organized and existing under the
laws of the State of Delaware, hereby promises to pay to _____________________
___________________________, or registered assigns, the principal sum of
_____________ ______________ DOLLARS ($______________) on July 23, 2006, with
interest (computed on the basis of a 360-day year -- 30-day month) (a) on the
unpaid balance thereof at the rate of 11.28% per annum from the date hereof,
payable quarterly on the 23rd day of October, January, April and July in each
year, commencing with the October 23, January 23, April 23 or July 23 next
succeeding the date hereof, until the principal hereof shall have become due and
payable, and (b) so long as an Event of Default (as defined in the Note
Agreement referred to below) is continuing, on the unpaid balance thereof, any
overdue payment of interest and any overdue payment of any Yield Maintenance
Amount (as defined in the Note Agreement referred to below), payable quarterly
as aforesaid (or, at the option of the registered holder hereof, on demand), at
a rate per annum from time to time equal to the lesser of (a) the maximum rate
permitted by applicable law or (b) the greater of (i) 2.0% over the rate of
interest then in effect with respect to this Note or (ii) 2.0% over the rate of
interest publicly announced by The Bank of New York from time to time in New
York City as its Prime Rate.

     Payments of principal of, interest on and any Yield Maintenance Amount
payable with respect to this Note are to be made at the main office of The Bank
of New York in New York City or at such other place as the holder hereof shall
designate to the Company in writing, in lawful money of the United States of
America.

     This Note is one of a series of 11.28% Senior Subordinated Notes (the
"NOTES") issued pursuant to a Subordinated Note and Warrant Purchase Agreement,
dated as of July 23, 1998 (the "AGREEMENT"), between the Company and The
Prudential Insurance Company of America, is entitled to the benefits thereof and
is guaranteed by each of the Guaranty Agreements (as defined in the Agreement)
and secured by each of the Security Documents (as defined in the Agreement) in
favor of the Collateral Agent (as defined in the Agreement) for the benefit of
the holders of the Notes.  Capitalized terms used and not otherwise defined
herein have the meanings assigned to them in the Agreement.
<PAGE>
 
     This Note is a registered Note and, as provided in the Agreement, upon
surrender of this Note for registration of transfer, duly endorsed, or
accompanied by a written instrument of transfer duly executed, by the registered
holder hereof or such holder's attorney duly authorized in writing, a new Note
of like tenor for a like principal amount will be issued to, and registered in
the name of, the transferee.  Prior to due presentment for registration of
transfer, the Company may treat the person in whose name this Note is registered
as the owner hereof for the purpose of receiving payment and for all other
purposes, and the Company shall not be affected by any notice to the contrary.

     This Note is entitled to the benefits of the Security Documents and the
Guaranty Agreements. This Note is subject to required and optional prepayment,
in whole or from time to time in part, on the terms specified in the Note
Agreement.

     If an Event of Default, as defined in the Agreement, shall occur and be
continuing, the principal of this Note may be declared or otherwise become due
and payable in the manner and with the effect provided in the Agreement.

     The Company, and the purchaser and the registered holder of this Note
specifically intend and agree to limit contractually the amount of interest
payable under this Note to the maximum amount of interest lawfully permitted to
be charged under applicable law.  Therefore, none of the terms of this Note
shall ever be construed to create a contract to pay interest at a rate in excess
of the maximum rate permitted to be charged under applicable law, and neither
the Company nor any other party liable or to become liable hereunder shall ever
be liable for interest in excess of the amount determined at such maximum rate,
and the provisions of paragraph 12P of the Agreement shall control over any
contrary provision of this Note.

     THIS NOTE IS INTENDED TO BE PERFORMED IN THE STATE OF NEW YORK AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAW OF SUCH STATE.

                         REGISTRATION RIGHTS AGREEMENT



     REGISTRATION RIGHTS AGREEMENT, dated as of July 23, 1998, between BOOTS &
COOTS INTERNATIONAL WELL CONTROL, INC., a Delaware corporation (the "COMPANY"),
and THE PRUDENTIAL INSURANCE COMPANY OF AMERICA (the "PURCHASER").


     1.  Background.  The Company and the Purchaser have entered into that
certain Subordinated Note and Warrant Purchase Agreement (the "PURCHASE
AGREEMENT"), dated as of the date hereof, pursuant to which the Company has
agreed, among other things, to issue and sell its Common Stock Purchase Warrants
(the "WARRANTS"), evidencing rights to purchase an aggregate of 3,165,396
shares(subject to adjustment as provided therein) of the Company's common stock,
par value $0.00001 per share (the "COMMON STOCK"). This agreement shall become
effective upon the issuance of such Warrants.

     2.  Registration under Securities Act, etc.

     2.1.  Registration on Request.

     (a) Request by Holders of Warrants or Registrable Securities.  At any time
after July 23, 2000, the Requisite Holders may request in writing that the
Company effect the registration under the Securities Act of the number of
Registrable Securities held by the Requisite Holders and specified in such
request, provided, that such number shall constitute at least 33 1/3% of the
aggregate number of Registrable Securities.  Such request shall specify the
intended method of disposition thereof and whether or not such requested
registration is to be an underwritten offering. Promptly after receiving such
request, the Company will give written notice of such requested registration to
all other holders of Warrants or Registrable Securities and thereupon the
Company will use its best efforts to effect the registration under the
Securities Act of:

               (i) the Registrable Securities which the Company has been so
     requested to register by such holders, and

               (ii) all other Registrable Securities which the Company has been
     requested to register by such other holders of Warrants or Registrable
     Securities by written request given to the Company within 30 days after the
     giving of such written notice by the Company (which request shall specify
     the intended method of disposition of such 
<PAGE>
 
     Registrable Securities), all to the extent requisite to permit the
     disposition (in accordance with the intended methods thereof as aforesaid)
     of the Registrable Securities so to be registered.

Notwithstanding the foregoing, if at the time of any request to register
Registrable Securities pursuant to this Section 2.1(a) the Company is engaged in
a registered public offering or is otherwise engaged in a merger or acquisition
which, in the good faith determination of the Board of Directors of the Company,
would be materially adversely affected by the requested registration to the
material detriment of the Company, then the Company may at its option direct
that such request be delayed for a reasonable period not in excess of (x) 90
days from the effective date or termination of such offering or (y) 90 days from
the date of completion or termination of such merger or acquisition, as the case
may be, such right to delay a request to be exercised by the Company not more
than once during the period in which this Agreement is in effect; provided,
however, that if the Company does not file or abandons its plan for a registered
offering or merger or acquisition, then such request shall promptly proceed;
provided, further, that if the Company exercises its right to delay a request
within the one-year period immediately preceding the expiration date of the
Warrants, the Company, concurrently with the exercise of its right to delay such
request, shall extend such expiration date by an additional two years.

          (b) Registration of Other Securities.  Whenever the Company shall
effect a registration pursuant to this Section 2.1 in connection with an
underwritten offering by one or more holders of Registrable Securities, no
securities other than Registrable Securities shall be included among the
securities covered by such registration unless (a) the managing underwriter of
such offering shall have advised each holder of Registrable Securities to be
covered by such registration (and each holder of Warrants therefor) in writing
that the inclusion of such other securities would not adversely affect such
offering or (b) the holders of all Registrable Securities to be covered by such
registration (and the holders of all Warrants therefor) shall have consented in
writing to the inclusion of such other securities.

          (c) Registration Statement Form.  Registrations under this Section 2.1
shall be on such appropriate registration form of the Commission (i) as shall be
selected by the Company and as shall be reasonably acceptable to the Requisite
Holders and (ii) as shall permit the disposition of such Registrable Securities
in accordance with the intended method or methods of disposition specified in
their request for such registration.  The Company agrees to include in any such
registration statement all information which holders of Registrable Securities
being registered (or holders of Warrants therefor) shall reasonably request.

          (d) Expenses.  The Company will pay all Registration Expenses in
connection with any registration requested pursuant to this Section 2.1.

          (e) Effective Registration Statement.  A registration requested
pursuant to this Section 2.1 shall not be deemed to have been effected (i)
unless a registration statement with respect 

                                       2
<PAGE>
 
thereto has become effective, (ii) if after it has become effective, such
registration is interfered with by any stop order, injunction or other order or
requirement of the Commission or other governmental agency or court for any
reason, or (iii) if the conditions to closing specified in the purchase
agreement or underwriting agreement entered into in connection with such
registration are not satisfied.

          (f) Selection of Underwriters.  If a requested registration pursuant
to this Section 2.1 involves an underwritten offering, the underwriter or
underwriters thereof shall be selected by the Company with the approval of the
Requisite Holders.

          (g) Priority in Requested Registrations.  If a requested registration
pursuant to this Section 2.1 involves an underwritten offering, and the managing
underwriter shall advise the Company in writing (with a copy to each holder of
Warrants or Registrable Securities requesting registration) that, in its
opinion, the number of securities requested to be included in such registration
exceeds the number which can be sold in such offering within a price range
acceptable to the Requisite Holders, the Company will include in such
registration to the extent of the number which the Company is so advised can be
sold in such offering Registrable Securities requested to be included in such
registration, pro rata among the holders of Registrable Securities (or Warrants
therefor) requesting such registration on the basis of the percentage of such
Registrable Securities held by or issuable to such holders.  In connection with
any registration as to which the provisions of this clause (g) apply, no
securities other than Registrable Securities shall be covered by such
registrations, including, without limitation, securities that would otherwise be
includible under clause (b) of this Section 2.1.

          The holders of Warrants or Registrable Securities shall be entitled to
only one requested registration pursuant to this Section 2.1.

          2.2. Incidental Registration.

          (a) Right to Include Registrable Securities.  If the Company at any
time proposes to register any of its securities under the Securities Act (other
than by a registration on Form S-4 or S-8 or any successor or similar form and
other than pursuant to Section 2.1), whether or not for sale for its own
account, it will each such time give prompt written notice to all holders of
Warrants or Registrable Securities of its intention to do so and of such
holders' rights under this Section 2.2. Upon the written request of any such
holder made within 30 days after the receipt of any such notice (which request
shall specify the Registrable Securities intended to be disposed of by such
holder and the intended method of disposition thereof), the Company will use its
best efforts to effect the registration under the Securities Act of all
Registrable Securities which the Company has been so requested to register by
the holders thereof, provided that if, at any time after giving written notice
of its intention to register any securities and prior to the effective date of
the registration statement filed in connection with such registration, the
Company shall determine for any reason not to register or to delay registration
of such securities, the Company may, at its election, give written notice of

                                       3
<PAGE>
 
such determination to each holder of Warrants or Registrable Securities and,
thereupon, (i) in the case of a determination not to register, shall be relieved
of its obligation to register any Registrable Securities in connection with such
registration (but not from its obligation to pay the Registration Expenses in
connection therewith), without prejudice, however, to the rights of any holder
or holders of Warrants or Registrable Securities entitled to do so to request
that such registration be effected as a registration under Section 2.1, and (ii)
in the case of a determination to delay registering, shall be permitted to delay
registering any Registrable Securities, for the same period as the delay in
registering such other securities. No registration effected under this Section
2.2 shall be deemed to have been effected pursuant to Section 2.1 or shall
relieve the Company of its obligation to effect any registration upon request
under Section 2.1. The Company will pay all Registration Expenses in connection
with each registration of Registrable Securities requested pursuant to this
Section 2.2.

          (b) Priority in Incidental Registrations.  If (i) a registration
pursuant to this Section 2.2 involves an underwritten offering of the securities
so being registered, whether or not for sale for the account of the Company, to
be distributed (on a firm commitment basis) by or through one or more
underwriters of recognized standing under underwriting terms appropriate for
such a transaction, (ii) the Registrable Securities so requested to be
registered for sale are not also to be included in such underwritten offering
(because the Company has not been requested so to include such Registrable
Securities pursuant to Section 2.4 (b), or if so requested, is not obligated to
do so under Section 2.4 (b)), and (iii) the managing underwriter of such
underwritten offering shall inform the Company and the holders of Warrants or
Registrable Securities requesting such registration by letter of its belief that
the number of securities requested to be included in such registration exceeds
the number which can be sold in (or during the time of) such offering, then the
Company may include all securities proposed by the Company to be sold for its
own account and may decrease the number of Registrable Securities and other
securities of the Company so proposed to be sold and so requested to be included
in such registration (pro rata among the holders thereof on the basis of the
percentage of the securities of the Company held by such holders) to the extent
necessary to reduce the number of securities to be included in the registration
to the level recommended by the managing underwriter.

          2.3. Registration Procedures.  If and whenever the Company is required
to use its best efforts to effect the registration of any Registrable Securities
under the Securities Act as provided in Sections 2.1 and 2.2, the Company will
as expeditiously as possible:

          (i) prepare and (as soon thereafter as possible or in any event no
     later than 60 days after the end of the period within which requests for
     registration may be given to the Company) file with the Commission the
     requisite registration statement to effect such registration and thereafter
     use its best efforts to cause such registration statement to become
     effective, provided that the Company may discontinue any registration of
     its securities which are not Registrable Securities (and, under the
     circumstances specified in Section 2.2(a), its securities which are
     Registrable Securities) at any time prior to the effective date of the
     registration statement relating thereto;

                                       4
<PAGE>
 
          (ii) prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the Securities Act
     with respect to the disposition of all securities covered by such
     registration statement until such time as all of such securities have been
     disposed of in accordance with the intended methods of disposition by the
     seller or sellers thereof set forth in such registration statement;

          (iii)  furnish to each seller of Registrable Securities covered by
     such registration statement such number of conformed copies of such
     registration statement and of each such amendment and supplement thereto
     (in each case including all exhibits), such number of copies of the
     prospectus contained in such registration statement (including each
     preliminary prospectus and any summary prospectus) and any other prospectus
     filed under Rule 424 under the Securities Act, in conformity with the
     requirements of the Securities Act, and such other documents, as such
     seller may reasonably request;

          (iv) use its best efforts to register or qualify all Registrable
     Securities and other securities covered by such registration statement
     under such other securities or blue sky laws of such jurisdictions as each
     seller thereof shall reasonably request, to keep such registration or
     qualification in effect for so long as such registration statement remains
     in effect, and take any other action which may be reasonably necessary or
     advisable to enable such seller to consummate the disposition in such
     jurisdictions of the securities owned by such seller, except that the
     Company shall not for any such purpose be required to qualify generally to
     do business as a foreign corporation in any jurisdiction wherein it would
     not but for the requirements of this subdivision (iv) be obligated to be so
     qualified or to consent to general service of process in any such
     jurisdiction;

          (v) use its best efforts to cause all Registrable Securities covered
     by such registration statement to be registered with or approved by such
     other governmental agencies or authorities as may be necessary to enable
     the seller or sellers thereof to consummate the disposition of such
     Registrable Securities;

          (vi) furnish to each seller of Registrable Securities and each
     Requesting Holder a signed counterpart, addressed to such seller and such
     Requesting Holder (and underwriters, if any) of:

          (x) an opinion of counsel for the Company, dated the effective date of
          such registration statement (and, if such registration includes an
          underwritten public offering, dated the date of the closing under the
          underwriting agreement), reasonably satisfactory in form and substance
          to such seller, and

                                       5
<PAGE>
 
          (y) a "cold comfort" letter, dated the effective date of such
          registration statement (and, if such registration includes an
          underwritten public offering, dated the date of the closing under the
          underwriting agreement), signed by the independent public accountants
          who have certified the Company's financial statements included in such
          registration statement,

     covering substantially the same matters with respect to such registration
     statement (and the prospectus included therein) and, in the case of the
     accountants' letter, with respect to events subsequent to the date of such
     financial statements, as are customarily covered in opinions of issuer's
     counsel and in accountants' letters delivered to the underwriters in
     underwritten public offerings of securities and, in the case of the
     accountants' letter, such other financial matters, and, in the case of the
     legal opinion, such other legal matters, as such seller or such Requesting
     Holder, if any, may reasonably request;

          (vii)  notify each seller of Registrable Securities covered by such
     registration statement and each Requesting Holder, at any time when a
     prospectus relating thereto is required to be delivered under the
     Securities Act, upon discovery that, or upon the happening of any event as
     a result of which, the prospectus included in such registration statement,
     as then in effect, includes an untrue statement of a material fact or omits
     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances under which they were made, and at the request of any such
     seller or Requesting Holder promptly prepare and furnish to such seller or
     Requesting Holder a reasonable number of copies of a supplement to or an
     amendment of such prospectus as may be necessary so that, as thereafter
     delivered to the purchasers of such securities, such prospectus shall not
     include an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances under which they
     were made;

          (viii)  otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission, and make available to its security
     holders, as soon as reasonably practicable, an earnings statement covering
     the period of at least twelve months, but not more than eighteen months,
     beginning with the first full calendar month after the effective date of
     such registration statement, which earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act, and will furnish to each
     such seller at least five business days prior to the filing thereof a copy
     of any amendment or supplement to such registration statement or prospectus
     and shall not file any thereof to which any such seller shall have
     reasonably objected on the grounds that such amendment or supplement does
     not comply in all material respects with the requirements of the Securities
     Act or of the rules or regulations thereunder;

          (ix) provide and cause to be maintained a transfer agent and registrar
     for all Registrable Securities covered by such registration statement from
     and after a date not later than the effective date of such registration
     statement;

                                       6
<PAGE>
 
          (x) use its best efforts to cause all Registrable Securities covered
     by such registration statement to be listed on any securities exchange on
     which any of the Registrable Securities are then listed or to be quoted by
     the Nasdaq National Market (or any successor thereto or any comparable
     system) on which any of the Registrable Securities are then quoted; and

          (xi) enter into such agreements and take such other actions as the
     Requisite Holders shall reasonably request in order to expedite or
     facilitate the disposition of such Registrable Securities.

The Company may require each seller of Registrable Securities as to which any
registration is being effected to furnish the Company such information regarding
such seller and the distribution of such securities as the Company may from time
to time reasonably request in writing.

     Each holder of Registrable Securities agrees by acquisition of such
Registrable Securities that upon receipt of any notice from the Company of the
happening of any event of the kind described in the subdivision (vii) of this
Section 2.3, such holder will forthwith discontinue such holder's disposition of
Registrable Securities pursuant to the registration statement relating to such
Registrable Securities until such holder's receipt of the copies of the
supplemented or amended prospectus contemplated by subdivision (vii) of this
Section 2.3.

     2.4  Underwritten Offerings.

          (a) Requested Underwritten Offerings.  If requested by the
underwriters for any underwritten offering of Registrable Securities pursuant to
a registration requested under Section 2.1, the Company will enter into an
underwriting agreement with such underwriters for such offering, such agreement
to be satisfactory in substance and form to each holder of such Registrable
Securities (or Warrants therefor), the Company and the underwriters and to
contain such representations and warranties by the Company and such other terms
as are generally prevailing in agreements of this type, including, without
limitation, indemnities to the effect and to the extent provided in Section 2.7.
The holders of Registrable Securities to be distributed by such underwriters
shall be parties to such underwriting agreement and may, at their option,
require that any or all of the representations and warranties by, and the other
agreements on the part of, the Company to and for the benefit of such
underwriters shall also be made to and for the benefit of such holders of
Registrable Securities and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be conditions
precedent to the obligations of such holders of Registrable Securities.  Any
such holder of Registrable Securities shall not be required to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or agreements regarding such
holder, such holder's Registrable Securities and such holder's intended method
of distribution and any other representation required by law.

                                       7
<PAGE>
 
          (b) Incidental Underwritten Offerings.  If the Company at any time
proposes to register any of its securities under the Securities Act as
contemplated by Section 2.2 and such securities are to be distributed by or
through one or more underwriters, the Company will, if requested by any holder
of Warrants or Registrable Securities as provided in Section 2.2 and subject to
the provisions of Section 2.2(b), arrange for such underwriters to include all
the Registrable Securities to be offered and sold by such holder among the
securities to be distributed by such underwriters.  The holders of Registrable
Securities to be distributed by such underwriters shall be parties to the
underwriting agreement between the Company and such underwriters and may, at
their option, require that any or all of the representations and warranties by,
and the other agreements on the part of, the Company to and for the benefit of
such underwriters shall also be made to and for the benefit of such holders of
Registrable Securities and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be conditions
precedent to the obligations of such holders of Registrable Securities. Any such
holder of Registrable Securities shall not be required to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or agreements regarding such
holder, such holder's Registrable Securities and such holder's intended method
of distribution and any other representation required by law.

          2.5. Preparation; Reasonable Investigation.  In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the holders of Registrable
Securities registered under such registration statement (or the holders of
Warrants therefor), their underwriters, if any, and their respective counsel and
accountants, the opportunity to participate in the preparation of such
registration statement, each prospectus included therein or filed with the
Commission, and each amendment thereof or supplement thereto, and will give each
of them such access to its books and records and such opportunities to discuss
the business of the Company with its officers and the independent public
accountants who have certified its financial statements as shall be necessary,
in the opinion of such holders' and such underwriters' respective counsel, to
conduct a reasonable investigation within the meaning of the Securities Act.

          2.6. Rights of Requesting Holders.  The Company will not file any
registration statement (other than on Form S-4 or S-8 or any successor or
similar form) under the Securities Act, unless it shall first have given to all
holders of Warrants or Registrable Securities at least 30 days prior written
notice thereof and, if so requested by the Requisite Holders in connection with
a registration of Registrable Securities under the Securities Act in a
transaction subject to Section 2.1 or 2.2, shall have consulted with such
holders concerning the selection of underwriters, counsel and independent
accountants for the Company for such offering and registration, provided, that
after such consultation, in the case of a transaction subject to Section 2.2,
the decision of the Company shall be conclusive.  If a holder or holders of
Registrable Securities shall so request within 30 days after such notice, each
of them shall be a "REQUESTING HOLDER" hereunder and shall have, in addition to
all other rights it may have under this Agreement and otherwise under applicable
law, the rights of a Requesting Holder provided in this section 2.6 and in
sections 2.3, 2.5 and 2.7.  The Company 

                                       8
<PAGE>
 
further covenants that a Requesting Holder shall have the right to participate
in the preparation of any such registration or comparable statement and to
request the insertion therein of material furnished to the Company in writing,
which in such Requesting Holder's judgment should be included. In addition, if
any such registration statement refers to any Requesting Holder by name or
otherwise as the holder of any securities of the Company, then such Requesting
Holder shall have the right to require (a) the insertion therein of language, in
form and substance satisfactory to such Requesting Holder, to the effect that
the holding by such Requesting Holder of such securities does not necessarily
make such Requesting Holder a "controlling person" of the Company within the
meaning of the Securities Act and is not to be construed as a recommendation by
such Requesting Holder of the investment quality of the Company's debt or equity
securities covered thereby and that such holding does not imply that such
Requesting Holder will assist in meeting any future financial requirements of
the Company, or (b) in the event that such reference to such Requesting Holder
by name or otherwise is not required by the Securities Act or any rules and
regulations promulgated thereunder, the deletion of the reference to such
Requesting Holder.

          2.7. Indemnification.

          (a) Indemnification by the Company.  In the event of any registration
of any securities of the Company under the Securities Act, the Company will, and
hereby does, (i) in the case of any registration statement filed pursuant to
Section 2.1 or 2.2 indemnify and hold harmless the seller of any Registrable
Securities covered by such registration statement, its directors and officers,
each other Person who participates as an underwriter in the offering or sale of
such securities and each other Person, if any, who controls such seller or any
such underwriter within the meaning of the Securities Act, and (ii) in the case
of any registration statement of the Company, indemnify and hold harmless any
Requesting Holder, its directors and officers and each other Person, if any, who
controls such Requesting Holder within the meaning of the Securities Act, in
each case against any losses, claims, damages or liabilities, joint or several,
to which such seller or Requesting Holder or any such director or officer or
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or any other noncompliance or alleged noncompliance with
the Securities Act or the applicable underwriting agreement, and the Company
will reimburse such seller, such Requesting Holder and each such director,
officer, underwriter and controlling person for any legal or any other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, liability, action or proceeding; provided that the Company
shall not be liable in any such case to the extent that any such loss, claim,
damage, liability (or action or proceeding in respect thereof) or expense arises
out of or is based upon an untrue statement or alleged untrue statement or
omission 

                                       9
<PAGE>
 
or alleged omission made in such registration statement, any such preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company through an instrument duly executed by such seller or Requesting Holder,
as the case may be, specifically stating that it is for use in the preparation
thereof and, provided further that the Company shall not be liable to any Person
who participates as an underwriter, in the offering or sale of Registrable
Securities or any other Person, if any, who controls such underwriter within the
meaning of the Securities Act, in any such case to the extent that any such
loss, claim, damage, liability (or action or proceeding in respect thereof) or
expense arises out of such Person's failure to send or give a copy of the final
prospectus, as the same may be then supplemented or amended, to the Person
asserting an untrue statement or alleged untrue statement or omission or alleged
omission at or prior to the written confirmation of the sale of Registrable
Securities to such Person if such statement or omission was corrected in such
final prospectus. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller or any such
director, officer, underwriter or controlling person and shall survive the
transfer of such securities by such seller.

          (b) Indemnification by the Sellers.  The Company may require, as a
condition to including any Registrable Securities in any registration statement
filed pursuant to Section 2.3, that the Company shall have received an
undertaking satisfactory to it from the prospective seller of such securities,
to indemnify and hold harmless (in the same manner and to the same extent as set
forth in subdivision (a) of this Section 2.7) the Company, each director of the
Company, each officer of the Company and each other Person, if any, who controls
the Company within the meaning of the Securities Act, with respect to any
statement or alleged statement in or omission or alleged omission from such
registration statement, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, if such
statement or alleged statement or omission or alleged omission was made in
reliance upon and in conformity with written information furnished to the
Company through an instrument duly executed by such seller specifically stating
that it is for use in the preparation of such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement.  Such indemnity shall remain in full force and effect, regardless of
any investigation made by or on behalf of the Company or any such director,
officer or controlling Person and shall survive the transfer of such securities
by such seller.

          (c) Notices of Claims, etc.  Promptly after receipt by an indemnified
party of notice of the commencement of any action or proceeding involving a
claim referred to in the preceding subdivisions of this Section 2.7, such
indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the latter of the commencement of
such action, provided that the failure of any indemnified party to give notice
as provided herein shall not relieve the indemnifying party of its obligations
under the preceding subdivisions of this Section 2.7, except to the extent that
the indemnifying party is actually prejudiced by such failure to give notice.
In case any such action is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and 

                                       10
<PAGE>
 
indemnifying parties may exist in respect of such claim, the indemnifying party
shall be entitled to participate in and to assume the defense thereof, jointly
with any other indemnifying party similarly notified to the extent that it may
wish, with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party for any legal or other expenses subsequently incurred by
the latter in connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the consent of the
indemnified party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified party of a release from all liability
in respect to such claim or litigation.

          (d) Other Indemnification.  Indemnification similar to that specified
in the preceding subdivisions of this Section 2.7 (with appropriate
modifications) shall be given by the Company and each seller of Registrable
Securities with respect to any required registration or other qualification of
securities under any Federal or state law or regulation of any governmental
authority other than the Securities Act.

          (e) Indemnification Payments.  The indemnification required by this
Section 2.7 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense as and when bills are received or
expense, loss, damage or liability is incurred.

          2.8. Adjustments Affecting Registrable Securities.  The Company will
not effect or permit to occur any combination or subdivision of shares which
would adversely affect the ability of the holders of Registrable Securities or
Warrants therefor to include such Registrable Securities in any registration of
its securities contemplated by this Section 2 or the marketability of such
Registrable Securities under any such registration.

          2.9. Delay in Effectiveness of Registration Statement.
Notwithstanding anything to the contrary contained in this Agreement, the
Company shall be permitted to delay the effectiveness of any registration
statement filed pursuant hereto for a period of 180 days after the effective
date of any registration statement filed by the Company in which Main Street
Merchant Partners II, L.P., or Geneva Associates, L.L.C., included shares of
Common Stock.

                         PARTICIPATION RIGHTS AGREEMENT


          PARTICIPATION RIGHTS AGREEMENT, dated as of  July 23, 1998, by and
among BOOTS & COOTS INTERNATIONAL WELL CONTROL, INC., a Delaware corporation
(the "COMPANY"), THE PRUDENTIAL INSURANCE COMPANY OF AMERICA (the "PURCHASER")
and the holders of the Company's common stock, par value $0.00001 per share (the
"COMMON STOCK") listed in Schedule I attached hereto (each a "STOCKHOLDER" and
collectively the "STOCKHOLDERS").

     1.  Background; Term.  The Company and the Purchaser have entered into a
Subordinated Note and Warrant Purchase Agreement (the "PURCHASE AGREEMENT"),
dated as of the date hereof, pursuant to which the Company has agreed, among
other things, to issue and sell its Common Stock Purchase Warrants (the
"WARRANTS"), evidencing rights to purchase an aggregate of [3,165,396] shares
(subject to adjustment as provided therein) of Common Stock.  This Agreement
shall become effective upon the issuance of such Warrants and shall terminate
(i) with respect to shares of Common Stock issued upon the exercise of the
Warrants, three years after the issuance of such shares, and (ii) with respect
to any other shares of Common Stock or Common Stock Equivalents, three years
after the issuance thereof.

     2.  Transfers of Common Stock.

     2.1 Rights of Participation.

          (a)  Participation Offer. Except as provided in Section 2.1(c),  if
any Stockholder or any Affiliate thereof (other than the Company or a
Subsidiary), or if the Company, proposes to sell or otherwise transfer for value
shares of  the Common Stock or Common Stock Equivalents (each such Stockholder,
each such Affiliate thereof and the Company being referred to herein as a
"TRANSFEROR"), which shares of the Common Stock or Common Stock Equivalents:

               (i) in the case of any sale or other transfer for value by any
     Transferor other than the Company, together with all shares of the Common
     Stock or Common Stock Equivalents sold or otherwise  transferred for value,
     whether in one transaction or in a series of related transactions, by such
     Transferor and all other Transferors (other than the Company), constitute
     at least 10% of the Fully Diluted Common Stock, or

               (ii) in the case of any sale or other transfer for  value by any
     Transferor (including the Company), together with all shares of the Common
     Stock or Common Stock Equivalents sold or otherwise transferred for value,
     whether in one transaction or in a series of related transactions, by such
     Transferor and all other Transferors (including the Company), constitute at
     least 30% of the Fully Diluted Common Stock,
<PAGE>
 
     then such Transferor shall offer (the "PARTICIPATION OFFER") to include in
     the proposed sale or other transfer a number of shares of Common Stock or
     Common Stock Equivalents (regardless of whether such securities are of the
     same class being sold or otherwise transferred by the Transferor)
     designated by each Tagalong Holder, not to exceed, in respect of such
     Tagalong Holder, the number of shares equal to the product of (y) the
     aggregate number of shares of Common Stock or Common Stock Equivalents to
     be sold or otherwise transferred by the Transferor to the proposed
     transferee and (z) a fraction, the numerator of which shall be the number
     of shares of Fully Diluted Common Stock held by such Tagalong Holder and
     the denominator of which shall be the number of shares of Fully Diluted
     Common Stock held by the Transferor and all Tagalong Holders.  The
     Transferor shall give written notice to each Tagalong Holder of the
     Participation Offer (the "PARTICIPATION OFFER NOTICE") at least 30 days
     prior to the proposed sale or other transfer.  The Participation Offer
     Notice shall specify the proposed transferee, the number of shares of
     Common Stock or Common Stock Equivalents to be sold or otherwise
     transferred to such transferee, the amount and type of consideration to be
     received therefor, and the place and date on which the sale or other
     transfer is to be consummated.

          (b) Exercise.  Each Tagalong Holder who wishes to include shares of
Common Stock or Common Stock Equivalents in the proposed sale or other transfer
in accordance with this Section 2.1 shall so notify the Transferor not more than
15 days after the date of receipt of the Participation Offer Notice.  The
Participation Offer shall be conditioned upon the Transferor's sale or other
transfer of shares pursuant to the transactions contemplated in the
Participation Offer Notice with the transferee named therein.  If any Tagalong
Holder or Holders have accepted the Participation Offer, the Transferor shall
reduce to the extent necessary the number of shares it otherwise would have sold
or transferred in the proposed sale or other transfer so as to permit such
Tagalong Holder or Holders to sell or otherwise transfer the number of shares
that it or they are entitled to sell or otherwise transfer under this Section
2.1, and the Transferor and such Tagalong Holder or Holders shall sell or
otherwise transfer the number of shares specified in the Participation Offer to
the proposed transferee in accordance with the terms of such sale or other
transfer set forth in the Participation Offer Notice.

          (c) Excepted Transfers.  Section 2.1(a) and Section 2.1(b) shall not
apply to any sale pursuant to a public offering registered pursuant to the
Securities Act, any sale pursuant to Rule 144 under the Securities Act (as such
rule may be amended from time to time) or to any sale or other transfer for
value by a Transferor (other than the Company or a Subsidiary) to an Affiliate
thereof (other than the Company or a Subsidiary) or to any sale or other
transfer for value by the Company as consideration for the acquisition of a
business or property.

          2.2  Restrictive Legend.  Contemporaneously with the execution and
delivery of this Agreement, each certificate representing shares of presently
outstanding Common Stock held by a Stockholder shall be stamped or otherwise

                                       2
<PAGE>
 
imprinted with a legend (or shall be exchanged for certificates bearing a
legend) in substantially the following form:

     restrictions set forth in a Participation Rights Agreement dated as of July
     23, 1998 among the Corporation, The Prudential Insurance Company of America
     and the holders of the Corporation's outstanding Common Stock parties
     thereto, and such shares may not be transferred except in compliance with
     such restrictions.  Such Participation Rights Agreement is on file at the
     office of the Corporation and a copy thereof will be furnished without
     charge to the holder of the shares represented by this certificate upon
     written request."

Each certificate issued upon the direct or indirect transfer of any such
outstanding Common Stock held by a Stockholder shall also be stamped or
otherwise imprinted with the foregoing legend.

          2.3  Effect of Violation.  Any purported transfer of Common Stock or
Common Stock Equivalents which is not permitted by this Agreement or which is in
violation of this Agreement shall be void and of no force and effect whatsoever.

                         COMMON STOCK PURCHASE WARRANT


                                                        NO. WA-1  JULY 23, 1998
PPN 099469 2 * 8


          BOOTS & COOTS INTERNATIONAL WELL CONTROL, INC. (the "COMPANY"), a
Delaware corporation, for value received, hereby certifies that THE PRUDENTIAL
INSURANCE COMPANY OF AMERICA or its registered assigns is entitled to purchase
from the Company 3,165,396 duly authorized, validly issued, fully paid and
nonassessable shares of the Company's common stock, par value $0.00001 per share
(the "ORIGINAL COMMON STOCK"), at an initial exercise price per share of $6.70
(subject to adjustment at the option of the Purchaser as set forth in section
1G), at any time or from time to time after July 23, 2000 (subject to the
exceptions set forth in section 1H), and prior to 5:00 p.m., New York City time,
on the later of (i) July 23, 2008 and (ii) six months after the date the Notes
(as defined below) are fully retired, all subject to the terms, conditions and
adjustments set forth below in this Warrant.

          This Warrant is one of the Common Stock Purchase Warrants (the
"WARRANTS", such term to include all Warrants issued in substitution therefor)
originally issued in connection with the issue and sale by the Company of the
Company's 11.28% Senior Subordinated Notes due July 23, 2006, in the aggregate
principal amount of $30,000,000 (the "NOTES") pursuant to that certain
Subordinated Note and Warrant Purchase Agreement dated of even date herewith
(the "PURCHASE AGREEMENT") between the Company and The Prudential Insurance
Company of America (the "PURCHASER").  The Warrants originally so issued
evidence rights to purchase an aggregate of 3,165,396 shares of Original Common
Stock, subject to adjustment as provided herein.  The term "NOTES" as used
herein shall include each Note delivered pursuant to any provision of the
Purchase Agreement and each Note delivered in substitution or exchange for any
such Note pursuant to any such provision.  Certain capitalized terms used in
this Warrant are defined in section 13.

     1.  Exercise of Warrant.

          1A.  Manner of Exercise.  This Warrant may be exercised by the holder
hereof, in whole or in part, during normal business hours on any Business Day on
or after July 23, 2000 (subject to the exceptions set forth in section 1H), and
prior to 5:00 p.m., New York City time, on the later of (a) July 23, 2008 and
(b) six months after the date the Notes are fully retired, by surrender of this
Warrant, with the form of subscription at the end hereof (or a reasonable
facsimile thereof) duly executed by such holder, to the Company at its principal
office (or, if such exercise shall be in connection with an underwritten public
offering of shares of Common Stock (or Other Securities) subject to this
Warrant, at the location at which the underwriters shall have agreed to accept
delivery thereof), accompanied by payment, in cash or by certified or official
bank check payable to the order of the Company, in the amount obtained by
multiplying (a) the number of shares of Original Common Stock (without giving
effect to any adjustment therein) designated in such form of subscription by (b)
the Exercise Price.  The number of duly authorized, validly issued, fully paid
and nonassessable shares of Common Stock which the holder of this Warrant shall
be entitled to receive upon each exercise hereof shall be determined by
multiplying the number of shares of Common Stock which would otherwise (but for
the provisions of section 2) be issuable upon such exercise, as designated by
the holder hereof pursuant to this section 1A, by a fraction of which (a) the
numerator is the Initial Exercise Price and (b) the denominator is the Exercise
Price in effect on the date of such exercise.  The "EXERCISE PRICE" shall
initially be the Initial Exercise Price per share, shall be adjusted and
readjusted from time to time as provided in section 2 (including, without
limitation, adjustments thereunder in the circumstances contemplated by the
final sentence of section 1G) and, as so adjusted and readjusted, shall remain
in effect until a further adjustment or readjustment thereof is required by
section 2.

          1B.  When Exercise Effective.  Each exercise of this Warrant shall be
deemed to have been effected and the Exercise Price shall be determined
immediately prior to the close of business on the Business Day on which this
Warrant shall have been surrendered to the Company as provided in section 1A,
and at such time the person or persons in whose name or names any certificate or
certificates for shares of Original Common Stock (or Other Securities) shall be
issuable upon such exercise as provided in section 1C shall be deemed to have
become the holder or holders of record thereof.

          1C.  Delivery of Stock Certificates, etc.  Promptly after the exercise
of this Warrant, in whole or in part, and in any event within five Business Days
thereafter (unless such exercise shall be in connection with an underwritten
public offering of shares of Common Stock (or Other Securities) subject to this
Warrant, in which event concurrently with such exercise), the Company at its
expense will cause to be issued in the name of and delivered to the holder
hereof or, subject to section 8, as such holder may direct,

               (a) a certificate or certificates for the number of duly
     authorized, validly issued, fully paid and nonassessable shares of Common
     Stock (or Other Securities) to which such holder shall be entitled upon
     such exercise, and

               (b) in case such exercise is in part only, a new Warrant or
     Warrants of like tenor, specifying on the face or faces thereof the number
     of shares of Common Stock 
<PAGE>
 
                                                                          Page 3

     equal to the number of such shares specified on the face of this Warrant
     minus the number of such shares designated by the holder upon such exercise
     as provided in section 1A.

          1D.  Company to Reaffirm Obligations.  The Company will, at the time
of or at any time after each exercise of this Warrant, upon the request of the
holder hereof or of any shares of Common Stock (or Other Securities) issued upon
such exercise, acknowledge in writing its continuing obligation to afford to
such holder all rights to which such holder shall continue to be entitled after
such exercise in accordance with the terms of this Warrant, provided that if any
such holder shall fail to make any such request, the failure shall not affect
the continuing obligation of the Company to afford such rights to such holder.

          1E.  Fractional Shares.  No fractional shares shall be issued upon
exercise of this Warrant and no payment or adjustment shall be made upon any
exercise on account of any cash dividends (except as provided in section 2B) on
the Common Stock or Other Securities issued upon such conversion.  If any
fractional interest in a share of Common Stock would, except for the provisions
of the first sentence of this section 1E, be deliverable upon the exercise of
this Warrant, the Company shall, in lieu of delivering the fractional share
therefor, pay to the holder exercising this Warrant an amount in cash equal to
the Market Price of such fractional interest.

          1F.  Cashless Exercise.   As an alternative to exercise of this
Warrant by payment in cash (or by certified or official bank check), as provided
above in section 1A, the holder of this Warrant may exercise its right to
purchase some or all of the shares of Common Stock pursuant to this Warrant, on
a net basis without the exchange of any funds (a "CASHLESS EXERCISE"), such that
the holder hereof receives the total number of shares of Common Stock subscribed
for pursuant to this Warrant reduced by that number of shares of Common Stock,
valued at Market Price, at the time of exercise equal to the aggregate Exercise
Price that would otherwise have been paid by the holder of this Warrant for such
total number of shares of Common Stock.

          1G.  Unilateral Change of Initial Exercise Price.  The holder hereof
shall have the unilateral right, but not the obligation, exercisable by written
notice (the "CHANGE NOTICE") to the Company given at any time after July 23,
2000 and prior to September 22, 2000 to change the Initial Exercise Price to the
amount that equals  the average Market Value of one share of Common Stock for
the thirty (30) trading days prior to July 23, 2000.  The change in the Initial
Exercise Price shall be retroactive to the date of this Warrant.  Upon the
change in the Initial Exercise Price, the Exercise Price  at the time of the
Change  Notice (but prior to giving effect thereto) shall be redetermined by
adjusting the Initial Exercise Price (as so changed) to take into account all
adjustments pursuant to section 2 hereof, other than adjustments for
transactions or events of the type addressed by sections 2B and 2F, that have
occurred after the date of this Warrant and prior to the Change Notice.

          1H.  Incidental Registrations; Participation Rights.  Notwithstanding
anything to the contrary contained in this Warrant, this Warrant shall be
exercisable prior to July 23, 2000 in
<PAGE>
 
                                                                          Page 4

connection with the exercise by the holder hereof of its rights under Section
2.2 of the Registration Rights Agreement or its rights under the Participation
Rights Agreement.

     2.   Protection Against Dilution or Other Impairment of Rights; Adjustment
of Exercise Price.

          2A.  Issuance of Additional Shares of Common Stock.  In case the
Company, at any time or from time to time after the date hereof (the "INITIAL
DATE"), shall issue or sell Additional Shares of Common Stock (including
Additional Shares of Common Stock deemed to be issued pursuant to section 2C or
2D but excluding Additional Shares of Common Stock issued upon the exercise of
Employee Options) without consideration or for a consideration per share
(determined pursuant to section 2E) less than the Market Price in effect on the
date of and immediately prior to such issue or sale, then, and in each such
case, subject to section 2H, the Exercise Price shall be reduced, concurrently
with such issue or sale, to a price (calculated to the nearest .001 of a cent)
determined by multiplying such Exercise Price by a fraction,

          (a) the numerator of which shall be (i) the number of shares of Common
     Stock outstanding immediately prior to such issue or sale plus (ii) the
     number of shares of Common Stock which the aggregate consideration received
     by the Company for the total number of such Additional Shares of Common
     Stock so issued or sold would purchase at such Market Price, and

          (b) the denominator of which shall be the number of shares of Common
     Stock outstanding immediately after such issue or sale,

provided that, for the purposes of this section 2A, (x) immediately after any
Additional Shares of Common Stock are deemed to have been issued pursuant to
section 2C or 2D, such Additional Shares shall be deemed to be outstanding, and
(y) treasury shares shall not be deemed to be outstanding.

          2B.    Extraordinary Dividends and Distributions.  In case the Company
at any time or from time to time after the date hereof shall declare, order, pay
or make a dividend or other distribution in respect of Common Stock or Other
Securities (including, without limitation, any distribution of other or
additional stock or other securities or property or Options by way of dividend
or spin-off, reclassification, recapitalization or similar corporate
rearrangement and any redemption or acquisition of any such stock or Options on
the Common Stock), other than (a) a dividend payable in Additional Shares of
Common Stock or in Options for Common Stock or (b) a regular periodic dividend
payable in cash then, and in each such case, the Company shall hold in trust,
for the benefit of the holder of this Warrant, commencing on the date such
dividend or other distribution is paid to the holders of Common Stock, the
securities and other property (including cash) which such holder would have
received if such holder had exercised this Warrant immediately prior to the
record date fixed in connection with such dividend or other distribution. The
Company will pay over to the holder of this Warrant, on any date this Warrant is
exercised, an amount of property held in such trust that is equal to the total
amount of property held in such trust on such
<PAGE>
 
                                                                          Page 5

date multiplied by a fraction, the numerator of which is the number of shares of
Common Stock issued pursuant to such exercise and the denominator of which is
the total number of shares of Common Stock the holder of this Warrant was
permitted to purchase upon the exercise hereof immediately prior to such
exercise. Upon the expiration of this Warrant (and compliance with the
immediately preceding sentence) such trust will be canceled and the property
held in such trust shall be returned to the Company.

          2C.  Treatment of Options and Convertible Securities.  In case the
Company, at any time or from time to time after the date hereof, shall issue,
sell, grant or assume, or shall fix a record date for the determination of
holders of any class of securities entitled to receive, any Options or
Convertible Securities, whether or not such Options or the right to convert or
exchange any such Convertible Securities are immediately exercisable, then, and
in each such case, the maximum number of Additional Shares of Common Stock (as
set forth in the instrument relating thereto, without regard to any provisions
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or, in the case of Convertible Securities and Options
therefor, issuable upon the conversion or exchange of such Convertible
Securities (or the exercise of such Options for Convertible Securities and
subsequent conversion or exchange of the Convertible Securities issued), shall
be deemed to be Additional Shares of Common Stock issued as of the time of such
issue, sale, grant or assumption or, in case such a record date shall have been
fixed, as of the close of business on such record date, provided, that such
Additional Shares of Common Stock shall not be deemed to have been issued (i) if
such Options constitute Employee Options or (ii) unless the consideration per
share (determined pursuant to section 2E) of such shares would be less than the
Market Price in effect on the date of and immediately prior to such issue, sale,
grant or assumption or immediately prior to the close of business on such record
date or, if the Common Stock trades on an ex-dividend basis, on the date prior
to the commencement of ex-dividend trading, as the case may be, and provided,
further, that in any such case in which Additional Shares of Common Stock are
deemed to be issued,

          (a) if an adjustment of the Exercise Price shall be made upon the
     fixing of a record date as referred to in the first sentence of this
     section 2C, no further adjustment of the Exercise Price shall be made as a
     result of the subsequent issue or sale of any Options or Convertible
     Securities for the purpose of which such record date was set;

          (b) no further adjustment of the Exercise Price shall be made upon the
     subsequent issue or sale of Additional Shares of Common Stock or
     Convertible Securities upon the exercise of such Options or the conversion
     or exchange of such Convertible Securities;

          (c) if such Options or Convertible Securities by their terms provide,
     with the passage of time or otherwise, for any change in the consideration
<PAGE>
 
                                                                          Page 6

     payable to the Company, or change in the number of Additional Shares of
     Common Stock issuable, upon the exercise, conversion or exchange thereof
     (by change of rate or otherwise), the Exercise Price computed upon the
     original issue, sale, grant or assumption thereof (or upon the occurrence
     of the record date with respect thereto), and any subsequent adjustments
     based thereon, shall, upon any such change becoming effective, be
     recomputed to reflect such change insofar as it affects such Options, or
     the rights of conversion or exchange under such Convertible Securities,
     which are outstanding at such time;

          (d) upon the expiration of any such Options or of the rights of
     conversion or exchange under any such Convertible Securities which shall
     not have been exercised (or upon purchase by the Company and cancellation
     or retirement of any such Options which shall not have been exercised or of
     any such Convertible Securities the rights of conversion or exchange under
     which shall not have been exercised), the Exercise Price computed upon the
     original issue, sale, grant or assumption thereof (or upon the occurrence
     of the record date with respect thereto), and any subsequent adjustments
     based thereon, shall, upon such expiration (or such cancellation or
     retirement, as the case may be), be recomputed as if:

               (i) in the case of Options for Common Stock or in the case of
          Convertible Securities, the only Additional Shares of Common Stock
          issued or sold (or deemed issued or sold) were the Additional Shares
          of Common Stock, if any, actually issued or sold upon the exercise of
          such Options or the conversion or exchange of such Convertible
          Securities and the consideration received therefor was (x) an amount
          equal to (A) the consideration actually received by the Company for
          the issue, sale, grant or assumption of all such Options, whether or
          not exercised, plus (B) the consideration actually received by the
          Company upon such exercise, minus (C) the consideration paid by the
          Company for any purchase of such Options which were not exercised, or
          (y) an amount equal to (A) the consideration actually received by the
          Company for the issue, sale, grant or assumption of all such
          Convertible Securities which were actually converted or exchanged,
          plus (B) the additional consideration, if any, actually received by
          the Company upon such conversion or exchange, minus (C) the excess, if
          any, of the consideration paid by the Company for any purchase of such
          Convertible Securities, the rights of conversion or exchange under
          which were not exercised, over an amount that would be equal to the
          Fair Value of the Convertible Securities so purchased if such
          Convertible Securities were not convertible into or exchangeable for
          Additional Shares of Common Stock, and

               (ii) in the case of Options for Convertible Securities, only the
     Convertible Securities, if any, actually issued or sold upon the exercise
     of 
<PAGE>
 
                                                                          Page 7

     such Options were issued at the time of the issue, sale, grant or
     assumption of such Options, and the consideration received by the Company
     for the Additional Shares of Common Stock deemed to have then been issued
     was an amount equal to (x) the consideration actually received by the
     Company for the issue, sale, grant or assumption of all such Options,
     whether or not exercised, plus (y) the consideration deemed to have been
     received by the Company (pursuant to section 2E) upon the issue or sale of
     the Convertible Securities with respect to which such Options were actually
     exercised, minus (z) the consideration paid by the Company for any purchase
     of such Options which were not exercised; and

          (e) no recomputation pursuant to subsection (c) or (d) above shall
     have the effect of increasing the Exercise Price then in effect by an
     amount in excess of the amount of the adjustment thereof originally made in
     respect of the issue, sale, grant or assumption of such Options or
     Convertible Securities.

          2D.  Treatment of Stock Dividends, Stock Splits, Etc.  In case the
Company, at any time or from time to time after the date hereof, shall declare
or pay any dividend or other distribution on any class of securities of the
Company payable in shares of Common Stock, or shall effect a subdivision of the
outstanding shares of Common Stock into a greater number of shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in Common
Stock), then, and in each such case, Additional Shares of Common Stock shall be
deemed to have been issued (a) in the case of any such dividend or other
distribution, immediately after the close of business on the record date for the
determination of holders of any class of securities entitled to receive such
dividend or other distribution, or (b) in the case of any such subdivision, at
the close of business on the day immediately prior to the day upon which such
corporate action becomes effective.

          2E.  Computation of Consideration.  For the purposes of this Warrant:

          (a) The consideration for the issue or sale of any Additional Shares
     of Common Stock or for the issue, sale, grant or assumption of any Options
     or Convertible Securities, irrespective of the accounting treatment of such
     consideration,

               (i) insofar as it consists of cash, shall be computed as the
          amount of cash received by the Company, and insofar as it consists of
          securities or other property, shall be computed as of the date
          immediately preceding such issue, sale, grant or assumption as the
          Fair Value of such consideration (or, if such consideration is
          received for the issue or sale of Additional Shares of Common Stock
          and the Market Price thereof is less than the Fair Value of such
          consideration, then such consideration shall be computed as the Market
          Price of such Additional Shares of Common 
<PAGE>
 
                                                                          Page 8

          Stock), in each case without deducting any expenses paid or incurred
          by the Company, any commissions or compensation paid or concessions or
          discounts allowed to underwriters, dealers or other performing similar
          services and any accrued interest or dividends in connection with such
          issue or sale, and

               (ii) in case Additional Shares of Common Stock are issued or sold
          or Options or Convertible Securities are issued, sold, granted or
          assumed together with other stock or securities or other assets of the
          Company for a consideration which covers both, shall be the proportion
          of such consideration so received, computed as provided in clause (i)
          above, allocable to such Additional Shares of Common Stock or Options
          or Convertible Securities, as the case may be, all as determined in
          good faith by the Board of Directors or the Company.

          (b) All Additional Shares of Common Stock, Options or Convertible
     Securities issued in payment of any dividend or other distribution on any
     class of stock of the Company and all Additional Shares of Common Stock
     issued to effect a subdivision of the outstanding shares of Common Stock
     into a greater number of shares of Common Stock (by reclassification or
     otherwise than by payment of a dividend in Common Stock) shall be deemed to
     have been issued without consideration.

          (c) Additional Shares of Common Stock deemed to have been issued for
     consideration pursuant to section 2C, relating to Options and Convertible
     Securities, shall be deemed to have been issued for a consideration per
     share determined by dividing

               (i) the total amount, if any, received and receivable by the
          Company as consideration for the issue, sale, grant or assumption of
          the Options or Convertible Securities in question, plus the minimum
          aggregate amount of additional consideration (as set forth in the
          instruments relating thereto, without regard to any provision
          contained therein for a subsequent adjustment of such consideration)
          payable to the Company upon the exercise in full of such Options or
          the conversion or exchange of such Convertible Securities or, in the
          case of Options for Convertible Securities, the exercise of such
          Options for Convertible Securities and the conversion or exchange of
          such Convertible Securities, in each case computing such consideration
          as provided in the foregoing subsection (a),

     by

               (ii) the maximum number of shares of Common Stock (as set forth
          in the instruments relating thereto, without regard to any provision
<PAGE>
 
                                                                          Page 9

          contained therein for a subsequent adjustment of such number) issuable
          upon the exercise of such Options or the conversion or exchange of
          such Convertible Securities.

          2F.  Adjustments for Combinations, Etc.  In case the outstanding
shares of Common Stock shall be combined or consolidated, by reclassification or
otherwise, into a lesser number of shares of Common Stock, the Exercise Price in
effect immediately prior to such combination or consolidation shall,
concurrently with the effectiveness of such combination or consolidation, be
proportionately increased.

          2G.  Dilution in Case of Other Securities.  In case any Other
Securities shall be issued or sold or shall become subject to issue or sale upon
the conversion or exchange of any stock (or Other Securities) of the Company (or
any issuer of Other Securities or any other Person referred to in section 2I) or
to subscription, purchase or other acquisition pursuant to any Options issued or
granted by the Company (or any such other issuer or Person) for a consideration
such as to dilute, on a basis to which the standards established in the other
provisions of this Warrant do not apply, the exercise rights granted by this
Warrant, then, and in each such case, the computations, adjustments and
readjustments provided for in this Warrant with respect to the Exercise Price
shall be made as nearly as possible in the manner so provided and applied to
determine the amount of Other Securities from time to time receivable upon the
exercise of this Warrant, so as to protect the holder of this Warrant against
the effect of such dilution.

          2H.  Minimum Adjustment of Exercise Price.  If the amount of any
adjustment of the Exercise Price required hereunder would be less than one
percent of the Exercise Price in effect at the time such adjustment is otherwise
so required to be made, such amount shall be carried forward and adjustment with
respect thereto made at the time of and together with any subsequent adjustment
which, together with such amount and any other amount or amounts so carried
forward, shall aggregate at least one percent of such Exercise Price; provided,
that upon the exercise of this Warrant, all adjustments carried forward and not
theretofore made up to and including the date of such exercise shall be made to
the nearest .001 of a cent.

          2I.  Changes in Common Stock.  In case at any time the Company shall
be a party to any transaction (including, without limitation, a merger,
consolidation, sale of all or substantially all of the Company's assets,
liquidation or recapitalization of the Common Stock) in which the previously
outstanding Common Stock shall be changed into or exchanged for different
securities of the Company or common stock or other securities of another
corporation or interests in a noncorporate entity or other property (including
cash) or any combination of any of the foregoing or in which the Common Stock
ceases to be a publicly traded security either listed on the New York Stock
Exchange or the American Stock Exchange or quoted by the Nasdaq National Market
or any successor thereto or comparable system (each such transaction being
herein called the "TRANSACTION", the date on which the Transaction is first
<PAGE>
 
                                                                         Page 10

announced to the public being herein called the "ANNOUNCEMENT DATE", the date of
consummation of the Transaction being herein called the "CONSUMMATION DATE", the
Company (in the case of a recapitalization of the Common Stock or any other such
transaction in which the Company retains substantially all of its assets and
survives as a corporation) or such other corporation or entity (in each other
case) being herein called the "ACQUIRING COMPANY", and the common stock (or
equivalent equity interest) of the Acquiring Company being herein called the
"ACQUIRER'S COMMON STOCK", except that if the Acquiring Company shall not meet
the requirements set forth in subsections (d), (e) and (f) below and a
corporation which directly or indirectly controls the Acquiring Company (a
"PARENT") meets such requirements, "Acquiring Company" shall refer to such
Parent and "Acquirer's Common Stock" shall refer to such Parent's common stock
(or equivalent equity interests)) then, as a condition of the consummation of
the Transaction, lawful and adequate provisions (in form satisfactory to the
Required Holders) shall be made so that the holder of this Warrant, upon the
exercise thereof at any time on or after the Consummation Date (but subject, in
the case of an election pursuant to subsection (b) or (c) below, to the time
limitation hereinafter provided for such election) shall be entitled to receive,
and this Warrant shall thereafter represent the right to receive, in lieu of the
Common Stock issuable upon such exercise prior to the Consummation Date, either:

          (a) shares of the Acquirer's Common Stock at an Exercise Price per
     share equal to the Exercise Price in effect immediately prior to the
     Consummation Date multiplied by a fraction the numerator of which is the
     Market Price per share of the Acquirer's Common Stock determined as of the
     Consummation Date and the denominator of which is the Market Price per
     share of the Common Stock determined as of the Consummation Date (subject
     to adjustments from and after the Consummation Date as nearly equivalent as
     possible to the adjustments provided for in this Warrant); or,

          (b) at the election of the holder of this Warrant pursuant to notice
     given to the Company within six months after the Consummation Date, either
     (i) the greatest amount of cash, securities or other property given to any
     shareholder in consideration for any share of Common Stock at any time
     during the period from and after the Announcement Date to and including the
     Consummation Date by the Acquiring Company, the Company or any Affiliate of
     either thereof, or (ii) an amount in cash equal to the product obtained by
     multiplying (x) the number of shares of the Acquirer's Common Stock
     purchasable upon the exercise or conversion of such Warrant as shall result
     from adjustments thereto that would have been required pursuant to
     subsection (a) above times (y) the Market Price per share for the
     Acquirer's Common Stock, determined as of the day within the period from
     and after the Announcement Date to and including the Consummation Date for
     which the amount determined as provided in the definition of Market Price
     shall have been the greatest, or,

          (c) if neither the Acquiring Company nor the Parent meets the
     requirements set forth in subsections (d), (e) and (f) below, at the
     election of the holder of this Warrant 
<PAGE>
 
                                                                         Page 11

     pursuant to notice given to the Company within six months after the
     Consummation Date, within 30 days after such election, in full satisfaction
     of the exercise rights afforded under this Warrant to the holder thereof,
     an amount equal to the Fair Value of such exercise rights, such Fair Value
     to be determined with regard to all material relevant factors but without
     regard to any negative effects on such value of the Transaction.

The Company agrees to obtain, and deliver to each holder of Warrants a copy of
the determination of an independent investment banker (selected by the Required
Holders with the approval of the Company) necessary to permit elections under
subsection (c) above within 15 days after the Consummation Date of any
Transaction to which subsection (c) is applicable.

          The requirements referred to above in the case of the Acquiring
Company or its Parent are that immediately after the Consummation Date:

          (d) it is a solvent corporation organized under the laws of any State
     of the United States of America having its common stock listed on the New
     York Stock Exchange or the American Stock Exchange or quoted by the Nasdaq
     National Market or any successor thereto or comparable system, and such
     common stock continues to meet such requirements for such listing or
     quotation,

          (e) it is required to file, and in each of its three fiscal years
     immediately preceding the Consummation Date has filed, reports with the
     Commission pursuant to Section 13 or 15(d) of the Exchange Act, and

          (f) in the case of the Parent, such Parent is required to include the
     Acquiring Company in the consolidated financial statements contained in the
     Parent's Annual Report on Form 10-K as filed with the Commission and is not
     itself included in the consolidated financial statements of any other
     Person (other than its consolidated subsidiaries).

Notwithstanding anything contained herein to the contrary, the Company shall not
effect any Transaction unless prior to the consummation thereof each corporation
or entity (other than the Company) which may be required to deliver any
securities or other property upon the exercise of Warrants shall assume, by
written instrument delivered to each holder of Warrants, the obligation to
deliver to such holder such securities or other property as to which, in
accordance with the foregoing provisions, such holder may be entitled, and such
corporation or entity shall have similarly delivered to each holder of Warrants
an opinion of counsel for such corporation or entity, satisfactory to each
holder of Warrants, which opinion shall state that all the outstanding Warrants
shall thereafter continue in full force and effect and shall be enforceable
against such corporation or entity in accordance with the terms hereof and
thereof, together with such other matters as such holders may reasonably
request.

                                                                         Page 12

          2J.  Certain Issues Excepted.  Anything herein to the contrary
notwithstanding, the Company shall not be required to make any adjustment of the
Exercise Price in the case of the issuance of the Warrants and the issuance of
shares of Common Stock issuable upon exercise of the Warrants.

          2K.  Notice of Adjustment.  Upon the occurrence of any event requiring
an adjustment of the Exercise Price, then and in each such case the Company
shall promptly deliver to the holder of this Warrant an Officer's Certificate'
stating the Exercise Price resulting from such adjustment and the increase or
decrease, if any, in the number of shares of Common Stock issuable upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.  Within 90 days
after each fiscal year in which any such adjustment shall have occurred, or
within 30 days after any request therefor by the holder of this Warrant stating
that such holder contemplates the exercise of such Warrant, the Company will
obtain and deliver to the holder of this Warrant the opinion of its regular
independent auditors or another firm of independent public accountants of
recognized national standing selected by the Company's Board of Directors, which
opinion shall confirm the statements in the most recent Officer's Certificate
delivered under this section 2K.

          2L.  Other Notices.  In case at any time:

          (a) the Company shall declare to the holders of Common Stock any
     dividend other than a regular periodic cash dividend or any periodic cash
     dividend in excess of 115% of the cash dividend for the comparable fiscal
     period in the immediately preceding fiscal year;

          (b) the Company shall declare or pay any dividend upon Common Stock
     payable in stock or make any special dividend or other distribution (other
     than regular cash dividends) to the holders of Common Stock;

          (c) the Company shall offer for subscription pro rata to the holders
     of Common Stock any additional shares of stock of any class or other
     rights;

          (d) there shall be any capital reorganization, or reclassification of
     the capital stock of the Company, or consolidation or merger of the Company
     with, or sale of all or substantially all of its assets to, another
     corporation or other entity;

          (e) there shall be a voluntary or involuntary dissolution, liquidation
     or winding-up of the Company;

          (f) there shall be made any tender offer for any shares of capital
     stock of the Company; or
<PAGE>
 
                                                                         Page 13

          (g) there shall be any other Transaction;

then, in any one or more of such cases, the Company shall give to the holder of
this Warrant (i) at least 15 days prior to any event referred to in subsection
(a) or (b) above, at least 30 days prior to any event referred to in subsection
(c), (d) or (e) above, and within five days after it has knowledge of any
pending tender offer or other Transaction, written notice of the date on which
the books of the Company shall close or a record shall be taken for such
dividend, distribution or subscription rights or for determining rights to vote
in respect of any such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation, winding-up or Transaction or the date by which
shareholders must tender shares in any tender offer and (ii) in the case of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, winding-up or tender offer or Transaction known to the Company, at
least 30 days prior written notice of the date (or, if not then known, a
reasonable approximation thereof by the Company) when the same shall take place.
Such notice in accordance with the foregoing clause (i) shall also specify, in
the case of any such dividend, distribution or subscription rights, the date on
which the holders of Common Stock shall be entitled thereto, and such notice in
accordance with the foregoing clause (ii) shall also specify the date on which
the holders of Common Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, 
winding-up, tender offer or Transaction, as the case may be. Such notice shall
also state that the action in question or the record date is subject to the
effectiveness of a registration statement under the Securities Act or to a
favorable vote of security holders, if either is required.

          2M.  Certain Events.  If any event occurs as to which, in the good
faith judgment of the Board of Directors of the Company, the other provisions of
this Warrant are not strictly applicable or if strictly applicable would not
fairly protect the exercise rights of the holders of the Warrants in accordance
with the essential intent and principles of such provisions, then the Board of
Directors of the Company shall appoint its regular independent auditors or
another firm of independent public accountants of recognized national standing
which shall give their opinion upon the adjustment, if any, on a basis
consistent with such essential intent and principles, necessary to preserve,
without dilution, the rights of the holders of the Warrants.  Upon receipt of
such opinion, the Board of Directors of the Company shall forthwith make the
adjustments described therein; provided, that no such adjustment shall have the
effect of increasing the Exercise Price as otherwise determined pursuant to this
Warrant.  The Company may make such reductions in the Exercise Price as it deems
advisable, including any reductions necessary to ensure that any event treated
for Federal income tax purposes as a distribution of stock or stock rights not
be taxable to recipients.

          2N.  Prohibition of Certain Actions.  The Company will not, by
amendment of its certificate or articles of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of 
<PAGE>
 
                                                                         Page 14

the terms to be observed or performed hereunder by the Company, but will at all
times in good faith assist in the carrying out of all the provisions of this
Warrant and in the taking of all such action as may reasonably be requested by
the holder of this Warrant in order to protect the exercise privilege of the
holder of this Warrant against dilution or other impairment, consistent with the
tenor and purpose of this Warrant. Without limiting the generality of the
foregoing, the Company (a) will not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the Exercise
Price then in effect, (b) will take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock upon the exercise of all Warrants from
time to time outstanding, (c) will not take any action which results in any
adjustment of the Exercise Price if the total number of shares of Common Stock
or Other Securities issuable after the action upon the exercise of all of the
Warrants would exceed the total number of shares of Common Stock or Other
Securities then authorized by the Company's certificate or articles of
incorporation and available for the purpose of issue upon such conversion, and
(d) will not issue any capital stock of any class which has the right to more
than one vote per share or any capital stock of any class which is preferred as
to dividends or as to the distribution of assets upon voluntary or involuntary
dissolution, liquidation or winding-up, unless the rights of the holders thereof
shall be limited to a fixed sum or percentage (or floating rate related to
market yields) of par value or stated value in respect of participation in
dividends and a fixed sum or percentage of par value or stated value in any such
distribution of assets.

     3.   Stock to be Reserved.  The Company will at all times reserve and keep
available out of the authorized Common Stock, solely for the purpose of issue
upon the exercise of the Warrants as herein provided, such number of shares of
Common Stock as shall then be issuable upon the exercise of all outstanding
Warrants and the Company will maintain at all times all other rights and
privileges sufficient to enable it to fulfill all its obligations hereunder.
The Company covenants that all shares of Common Stock which shall be so issuable
shall, upon issuance, be duly authorized, validly issued, fully paid and
nonassessable, free from preemptive or similar rights on the part of the holders
of any shares of capital stock or securities of the Company or any other Person,
and free from all taxes, liens and charges with respect to the issue thereof
(not including any income taxes payable by the holders of Warrants being
exercised in respect of gains thereon), and the Exercise Price will be credited
to the capital and surplus of the Company.  The Company will take all such
action as may be necessary to assure that such shares of Common Stock may be so
issued without violation of any applicable law or regulation, or of any
applicable requirements of the National Association of Securities Dealers, Inc.
and of any domestic securities exchange upon which the Common Stock may be
listed.

     4.   Registration of Common Stock.  If any shares of Common Stock required
to be reserved for purposes of the exercise of Warrants require registration
with or approval of any governmental authority under any Federal or State law
(other than the Securities Act, registration under which is governed by the
Registration Rights 
<PAGE>
 
                                                                         Page 15

Agreement), before such shares may be issued upon the exercise thereof, the
Company will, at its expense and as expeditiously as possible, use its best
efforts to cause such shares to be duly registered or approved, as the case may
be. Shares of Common Stock issuable upon exercise of the Warrants shall be
registered by the Company under the Securities Act or similar statute then in
force if required by the Registration Rights Agreement and subject to the
conditions stated in such agreement. At any such time as the Common Stock is
listed on any national securities exchange or quoted by the Nasdaq National
Market or any successor thereto or any comparable system, the Company will, at
its expense, obtain promptly and maintain the approval for listing on each such
exchange or quoting by the Nasdaq National Market or such successor thereto or
comparable system, upon official notice of issuance, the shares of Common Stock
issuable upon exercise of the then outstanding Warrants and maintain the listing
or quoting of such shares after their issuance so long as the Common Stock is so
listed or quoted; and the Company will also cause to be so listed or quoted,
will register under the Exchange Act and will maintain such listing or quoting
of, any Other Securities that at any time are issuable upon exercise of the
Warrants, if and at the time that any securities of the same class shall be
listed on such national securities exchange by the Company.

     5.   Issue Tax.  The issuance of certificates for shares of Common Stock
upon exercise of this Warrant shall be made without charge to the holders hereof
for any issuance tax in respect thereto.

     6.   Closing of Books.  The Company will at no time close its transfer
books against the transfer of any Warrant or of any share of Common Stock issued
or issuable upon the exercise of any Warrant in any manner which interferes with
the timely exercise of such Warrant.

     7.   No Rights or Liabilities as Stockholders.  This Warrant shall not
entitle the holder thereof to any of the rights of a stockholder of the Company,
except as expressly contemplated herein.  No provision of this Warrant, in the
absence of the actual exercise of such Warrant and receipt by the holder thereof
of Common Stock issuable upon such conversion, shall give rise to any liability
on the part of such holder as a stockholder of the Company, whether such
liability shall be asserted by the Company or by creditors of the Company.

     8.   Restrictive Legends.  Except as otherwise permitted by this section 8,
each Warrant originally issued and each Warrant issued upon direct or indirect
transfer or in substitution for any Warrant pursuant to this section 8 shall be
stamped or otherwise imprinted with a legend in substantially the following
form:

     "This Warrant and any shares acquired upon the exercise of this Warrant
     have not been registered under the Securities Act of 1933 and may not be
     transferred in the absence of such registration or an exemption therefrom
     under such Act."

Except as otherwise permitted by this section 8, (a) each certificate for
Original Common Stock 
<PAGE>
 
                                                                         Page 16

(or Other Securities) issued upon the exercise of any Warrant, and (b) each
certificate issued upon the direct or indirect transfer of any such Original
Common Stock (or Other Securities) shall be stamped or otherwise imprinted with
a legend in substantially the following form:

     "The shares represented by this certificate have not been registered under
     the Securities Act of 1933 and may not be transferred in the absence of
     such registration or an exemption therefrom under such Act."

The holder of any Restricted Securities shall be entitled to receive from the
Company, without expense, new securities of like tenor not bearing the
applicable legend set forth above in this section 8 when such securities shall
have been (a) effectively registered under the Securities Act and disposed of in
accordance with the registration statement covering such Restricted Securities,
(b) sold pursuant to Rule 144 or any comparable rule under the Securities Act,
(c) transferred to a limited number of "qualified institutional buyers" (as such
term is defined in Rule 144A under the Securities Act), each of which shall have
represented in writing that it is acquiring such Restricted Securities for
investment and not with a view to the disposition thereof, or (d) when, in the
opinion (which opinion must be reasonably satisfactory to the Company and its
securities counsel) of independent counsel for the holder thereof experienced in
Securities Act matters, such restrictions are no longer required in order to
insure compliance with the Securities Act.  The Company will pay the reasonable
fees and disbursements of counsel for any holder of Restricted Securities in
connection with all opinions rendered pursuant to this section 8.

     9.   Availability of Information.  The Company will cooperate with each
holder of any Restricted Securities in supplying such information as may be
necessary for such holder to complete and file any information reporting forms
presently or hereafter required by the Commission as a condition to the
availability of an exemption from the Securities Act for the sale of any
Restricted Securities. The Company will furnish to each holder of any Warrants,
promptly upon their becoming available, copies of all financial statements,
reports, notices and proxy statements sent or made available generally by the
Company to its stockholders, and copies of all regular and periodic reports and
all registration statements and prospectuses filed by the Company with any
securities exchange or with the Commission.

     10.  Information Required By Rule 144A.  The Company will, upon the request
of the holder of this Warrant, provide such holder, and any qualified
institutional buyer designated by such holder, such financial and other

           BOOTS & COOTS COMPLETES $45 MILLION CREDIT FINANCING
                    CLOSES ACQUISITION OF BAYLOR COMPANY

HOUSTON, JULY 27, 1998 -- Boots & Coots International Well Control, Inc.
(AMEX:WEL), the leading provider of global prevention and emergency response
well control services and well restoration to the oil and gas industry, said
today it has completed, with the assistance of Prudential Securities
Incorporated, a $45 million financing package with the Global Energy division of
Prudential Capital Group, consisting of a $15 million line of credit and $30
million in senior subordinated notes in the first phase of its planned capital
structure.

Chairman and Chief Executive Officer Larry Ramming, commented "We are pleased to
have Prudential as a long-term financial partner and appreciate the confidence
they have in our business plan. Prudential provides the strong foundation needed
to execute Boots & Coots' strategy of becoming the leading provider to oil and
gas companies of end-to-end solutions for emergencies--from prevention to
restoration of operations, anywhere in the world."

The Company also announced that it had completed the previously announced 
acquisition of privately held Baylor Company (1997 revenues: $31 million and net
income: $3.5 million). Terms were not disclosed.

                                    -more-

The Company said that the proceeds from this financing will replace funds used 
in the recent acquisition of Abasco, manufacturer and distributor of 
environmental safety and spill remediation equipment; ITS, global supply and 
logistics project management and outsource purchasing agent for the 
petrochemical industry; and Code 3, a rapidly expanding emergency response, 
hazardous materials and full environmental service provider. The proceeds were 
also used to close the acquisition of Baylor and provide working capital and 
funds for future acquisitions.

Chairman and Chief Executive Officer Larry Ramming said: "Houston-based Baylor 
adds substantially to Boots & Coots' single-solution emergency response 
capabilities, both as a revenue-producing, stand-alone entity and as a vital 
contributor to its long-term strategic positioning. Baylor provides the 
equipment necessary to take that critical last step in the process of resuming 
normal operations after oil and gas well emergencies." Its heavy manufacturing 
capability will help Boots & Coots' oil and gas customers avoid backlog delays 
of many months or even years for the equipment they need, Ramming explained. 
Time is a crucial factor in oil and gas production and emergency restoration 
management, and "Baylor's products and demonstrated capabilities can make the 
significant difference in restoring production expeditiously," he said.

Ramming noted that Baylor, founded in 1954, is a highly regarded manufacturer of
a varied line of industrial products, many of them proprietary. As a supplier to
the oil and gas services industry, Baylor provides both manufactured equipment 
and custom solutions for the drilling, marine and power generation industries. 
He added, "by incorporating Baylor's highly talented management team and 
manufacturing capability in our restoration projects, we can add directly to 
Baylor's revenue stream and serve our customers most critical needs."

Baylor's base line of products include Elmagco (R) Brakes, brake controls, brake
monitors, closed loop cooling systems, Thyrig (TH) Drive Systems, deepwater
thrusters and mooring systems as well as AC generators sold under the trade
names EMD, Delco and Baylor, worldwide.

On a pro forma basis, the Baylor acquisition and other recent acquisitions would
have increased Boots & Coots' calendar year 1997 Revenues and EBITDA to about 
$95 million and $9 million, respectively, if all of the acquisitions had been 
completed by the beginning of 1997.
