                               PROSPECTUS SUMMARY
 
  The following summary should be read in conjunction with, and is qualified in
its entirety by, the more detailed information and financial statements,
including the notes thereto, appearing elsewhere in this Prospectus. Unless
otherwise indicated, the information in this Prospectus (i) gives effect to the
reclassification of the Company's outstanding shares of Class A Common Stock
and Class B Common Stock effected December 12, 1997, and subsequent   -for-one
stock split of its Class A Common Stock and Class B Common Stock outstanding
effected     , 1998, and (ii) assumes that the Underwriters' over-allotment
option is not exercised. Unless otherwise indicated by the context, references
herein to the "Company" or "Red Man" mean Red Man Pipe & Supply Co., an
Oklahoma corporation, and references to "Common Stock" shall mean both the
Class A and Class B Common Stock.
 
                                  THE COMPANY
 
  Red Man is a leading distributor of products and services to the energy
industry. The Company distributes more than 55,000 products and tubular goods
through 42 service and supply centers and 11 sales locations strategically
located close to major hydrocarbon producing and refining areas of the United
States. In addition, through its membership in an association of distributors
with distribution centers in 35 states, the Company participates in certain
national accounts with other members. Due to the breadth of its products and
services, Red Man is able to serve the needs of companies in the upstream
(i.e., drilling and producing), midstream (i.e., gathering and transporting)
and downstream (i.e., processing, refining and manufacturing) sectors of the
energy industry. The Company believes it is one of only two companies that can
provide products and services to customers engaged in upstream-to-downstream
operations in major hydrocarbon producing and refining areas of the United
States.
 
  The Company's operations involve the distribution of tubular goods, including
oil country tubular goods ("OCTG") and line pipe, and the operation of service
and supply centers which distribute maintenance, repair and operating ("MRO")
products utilized in the energy industry, as well as industrial products
consisting primarily of line pipe, valves, fittings and flanges ("PVF"). In
fiscal 1997, sales of tubular goods represented approximately 55% of total
sales, and sales of other products from service and supply centers represented
approximately 45% of total sales.
 
  The Company distributes a broad range of OCTG and line pipe for oilfield and
industrial applications. The Company purchases OCTG and line pipe manufactured
by 23 domestic mills and four foreign mills and distributes these products
directly from the mills or from the Company's own inventory maintained in
storage yards strategically located throughout major hydrocarbon producing
regions of the United States. A significant portion of the Company's tubular
goods sales is made pursuant to stocking program arrangements with its
customers. Under such arrangements, the Company provides various specifications
of tubular goods at an agreed upon price generally for a period from three to
18 months.
 
  The Company's oilfield and industrial service and supply centers provide MRO
and PVF products and various related services to the upstream, midstream and
downstream operations of the energy industry, as well as to engineering and
construction companies, fabricators, drilling contractors, utilities,
processing plants and energy industry service companies. In addition, the
Company markets gas measurement products, consisting of meter tubes and skid-
mounted meter stations, and distributes measurement-related products and
services from its various service and supply centers.
 
  As major integrated and large independent oil and gas companies have begun
implementing cost-cutting and efficiency initiatives to focus on their core
business activities, many of these companies have begun outsourcing their
procurement and inventory management requirements. In response to these
initiatives, the Company provides a number of value added services, including
inventory procurement and management,
 
                                       4
<PAGE>
 
warehouse management, integrated supply arrangements, management information
reporting and total project management. These value added services are designed
to enable the Company's customers to operate more efficiently by reducing their
total procurement costs and the number of suppliers utilized.
 
  In addition, a number of major integrated and large independent oil and gas
companies are seeking strategic alliances with their suppliers and service
providers to establish service programs which enhance operating efficiencies.
The Company has developed and is actively pursuing strategic alliances with its
customers whereby a number of the Company's value added services may be
combined as needed to enable these customers to operate more efficiently. Red
Man also benefits from these alliances due to the longer term relationships
created. These relationships generally provide greater consistency and
predictability with respect to customer procurement requirements, improved
utilization of assets and increased inventory turnover. The Company initially
developed alliances to meet the needs of the upstream operations of its major
integrated and large independent oil and gas companies. However, the Company
has expanded certain of these alliances to provide products and services to the
midstream and downstream operations of its integrated customers. The Company's
major customers with which it has strategic alliances include Amoco Production
Company, Chevron USA, Inc., Coastal Management Corporation, Exxon Company,
U.S.A., Mobil Oil Corporation, OXY USA, Inc., Phillips Petroleum Company, Shell
Offshore Inc., Texaco, Inc., The Williams Companies, Inc. and Union Pacific
Resources Group, Inc. In addition, the Company has commenced developing
strategic alliances with industrial customers, including Kaiser Aluminum &
Chemical Corporation. The Company considers its efforts to obtain strategic
alliances with customers to be of major importance to its future growth.
 
  The Company has grown its business operations both through acquisitions and
internal expansion. Sales have grown at a 25.3% compounded annual growth rate
from $184.2 million in fiscal 1993 to $454.4 million in fiscal 1997. Net income
has grown over the same period at a 39.0% compounded annual growth rate from
$1.9 million to $7.1 million.
 
  The Company believes it is well positioned to continue as a leading
distributor of products and services to the energy industry. The Company
considers its competitive strengths to include: (i) business and geographical
diversification; (ii) value added services; (iii) relationships with customers;
(iv) experienced and incentivized management team; (v) relationships with mills
and suppliers; and (vi) the ability to manage growth and integrate
acquisitions.
 
STRATEGY
 
  The Company's goal is to expand its existing market position in the upstream,
midstream and downstream sectors of the energy industry, while at the same time
increasing its earnings and cash flow per share to enhance overall stockholder
value. Key elements of the Company's strategy for achieving this goal are to:
(i) maintain and grow customer alliances; (ii) increase MRO agreements; (iii)
expand into selected international markets; (iv) increase integrated supply
arrangements; (v) increase tubular goods sales; and (vi) capitalize on the
Company's strong balance sheet.

(1) EBITDA, or "earnings from continuing operations before interest expense,
    interest income, other (net), income taxes, depreciation and amortization,"
    is not a generally accepted accounting principle measure, but is a
    supplemental financial measurement used by the Company in the evaluation of
    its business. EBITDA should not be construed as an alternative to net
    income or to cash flow from operations or any other measure of performance
    in accordance with generally accepted accounting principles, and is
    presented solely as supplemental disclosure. EBITDA is a supplemental
    financial measure commonly used by investors in the oil services industry
    and is being presented in this prospectus because management believes that
    EBITDA provides supplemental information about the Company's ability to
    meet its future requirements for debt service, capital expenditures and
    working capital. Management utilizes EBITDA to aid it in assessing the
    financial performance of the Company. Because EBITDA excludes some, but not
    all, items that affect net income and this measure may vary among
    companies, the EBITDA data presented above may not be comparable to
    similarly titled measures of other companies.
(2) Adjusted to give effect to the Offering and the application of the net
    proceeds to the Company therefrom of approximately $   million (assuming an
    initial public offering price of $   per share). See "Use of Proceeds" and
    "Capitalization."

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business before purchasing the Class A Common Stock offered hereby. All
statements other than statements of historical facts included in this
Prospectus, including, without limitation, statements regarding the Company's
business strategy, plans and objectives of management of the Company for
future operations and future industry conditions, are forward-looking
statements. Although the Company believes that the expectations reflected in
such forward-looking statements are reasonable, it can give no assurance that
such expectations will be met. Important factors that could cause actual
results to differ materially from the Company's expectations are disclosed
below and elsewhere in this Prospectus.
 
DEPENDENCE ON ENERGY INDUSTRY AND VOLATILITY OF OIL AND GAS PRICES
 
  The Company's business is substantially dependent upon the condition of the
energy industry and, in particular, the willingness of companies to make
capital expenditures on exploration, drilling, production, gathering,
transportation, refining and processing operations. The level of capital
expenditures is dependent in part on the prevailing view of future oil and gas
prices, which are influenced by numerous factors affecting the supply and
demand for oil and gas, including worldwide economic activity, interest rates
and the cost of capital, environmental regulation, tax policies, coordination
by the Organization of Petroleum Exporting Countries, the cost of exploring
for and producing oil and gas, the discovery rate of new oil and gas reserves
and technological advances. Oil and gas prices and the level of drilling and
production activity have been characterized by significant volatility in
recent years. Although hydrocarbon prices have improved in recent years and
the level of exploration, drilling and production activity has increased,
there can be no assurance that such price and activity levels will be
sustained and that there will not be continued volatility in the level of
drilling and production related activities. A significant and prolonged
decline in hydrocarbon prices would likely have a material adverse effect on
the Company's business, financial condition or results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview" and "Business--Industry Overview."
 
COMPETITION
 
  The oilfield and industrial distribution services business is highly
competitive. The Company's sales and earnings can be affected by competitive
actions such as price changes, improved delivery and other actions by
competitors. Certain of its primary competitors are diversified multinational
companies with substantially larger operating staffs and greater capital
resources than those of the Company. See "Business--Competition."
 
RELIANCE ON SIGNIFICANT CUSTOMERS
 
  The Company's business is dependent on securing and maintaining customers by
promptly delivering reliable, cost-efficient products and services. For fiscal
1997, one of the Company's customers, Chevron USA, Inc., accounted for
approximately 12% of total sales. In addition, sales to the Company's top ten
customers accounted for approximately 49% of total sales in fiscal 1997. While
the Company believes it has excellent relationships with these significant
customers, the loss of one or more of such customers could have a material
adverse effect on the Company's business, financial condition or results of
operations. The products that the Company may sell to any particular customer
depend in large part on the size of that customer's capital expenditure budget
in a particular year and on the results of competitive bids for major
projects. Consequently, a customer that accounts for a significant portion of
sales in one fiscal year may represent an immaterial portion of sales in
subsequent years. See "Business--Customers."
 
RELIANCE ON SIGNIFICANT SUPPLIERS
 
  A substantial portion of the Company's tubular goods sales are purchased
from two manufacturers. The Company has no long-term supply contracts with
either of these manufacturers which would assure the Company of a continued
supply of tubular good products in the future. Although the Company believes
there are numerous
 
                                       8
<PAGE>
 
manufacturers having the capacity to supply its tubular good products, the
loss of one of these major suppliers could have a material adverse effect on
the Company's business, financial condition or results of operations as such
loss would require the Company to rely more heavily on its other existing
suppliers or develop relationships with new suppliers, which may cause the
Company to pay higher prices for products due to a loss of the volume discount
benefits currently obtained from its two major suppliers.
 
FLUCTUATIONS IN PRODUCT PRICES
 
  A significant amount of the Company's sales is derived from stocking program
arrangements, blanket contracts and MRO pricing agreements, each of which may
obligate the Company to sell products at a set price for the length of such
arrangement or agreement. Accordingly, the Company's operating margin could be
materially adversely affected by a significant increase in prices from its
suppliers that the Company is not able to pass on to its customers due to the
existing contractual relationship. The Company believes it can negotiate with
its customers in these circumstances to reduce the effects of unforseen price
increases because the Company has strong existing relationships with major
customers. However, there is no assurance that material price fluctuations
will not have a material adverse effect on the Company's business, financial
condition or results of operations.
 
  The Company is also subject to the risk that the value of its inventory will
decline as a result of price reductions by mills or other manufacturers of
products sold by the Company. While the Company believes the risk of a
material reduction in the value of its inventory is mitigated due to the fact
that it does not carry a significant amount of speculative inventory and that
its significant supply commitments are generally for relatively short-term
periods, there is no assurance that a substantial decline in product prices
would not result in a write-down of the Company's inventory value having a
material adverse effect on the Company's business, financial condition or
results of operations.
 
MANAGEMENT OF GROWTH
 
  Over the last ten years the Company has acquired a total of 42 service and
supply centers through five acquisitions, and it expects to continue to
evaluate acquisitions that can provide meaningful benefits by expanding the
Company's business and leveraging its existing infrastructure. However, there
are various risks associated with pursuing an acquisition strategy of this
nature, including problems inherent in integrating new operations. There is no
assurance that suitable acquisition candidates will be available, that
acquisitions can be completed on reasonable terms, that the Company will
successfully integrate the operations of any acquired entities or that the
Company will have access to adequate funds to effect any desired acquisitions.
Any inability on the part of the Company to integrate and manage the
operations of acquired businesses could have a material adverse effect on the
Company's business, financial condition or results of operations. In addition,
if the Company were to make any significant acquisition, it may be required to
incur substantial indebtedness, which may impose a significant interest and
principal repayment burden on the Company's operations, or issue equity
securities, which may result in significant dilution of the Company's then-
current stockholders' net book value per share.
 
DEPENDENCE ON KEY EMPLOYEES
 
  The Company's success depends to a large extent on the continued services of
the Company's senior executive officers. The Company currently does not have
written employment agreements with any senior executive officer. The loss of
services of one or more of its senior officers could have a material adverse
effect on the Company's business, financial condition or results of
operations. Furthermore, there can be no assurance that the Company will
continue to attract and retain sufficient qualified personnel. See
"Management."
 
POTENTIAL PRODUCT LIABILITY CLAIMS
 
  Certain products sold by the Company are used in potentially hazardous
applications that can cause personal injury, product liability and
environmental claims. A catastrophic occurrence at a location where products
sold by the Company are used may result in the Company being named as a
defendant in lawsuits asserting potentially large claims. Certain of these
risks are reduced by the fact that the Company is a distributor of products
produced
 
                                       9
<PAGE>
 
by third-party manufacturers. In such circumstances, the Company generally
would have third-party indemnification and/or warranty claims against the
manufacturer of products alleged to have been defective. However, there is no
assurance that such third-party claims could fully protect the Company or that
the manufacturer would be able financially to provide such protection. The
Company also maintains insurance coverage that it believes is customary in the
industry. However, such insurance does not provide coverage for all
liabilities (including liability for certain events involving pollution), and
there is no assurance that its insurance coverage will be adequate to cover
claims that may arise or that the Company will be able to maintain adequate
insurance at rates it considers reasonable. Although the Company to date has
not experienced any losses from product liability claims, the occurrence of an
event not fully covered by insurance or indemnification could have a material
adverse effect on the business, financial condition or results of operations
of the Company.
 
CONTROL BY CERTAIN MEMBERS OF MANAGEMENT
 
  Upon completion of the Offering, L. Craig Ketchum, Chief Executive Officer
and President of the Company, and Betty J. Ketchum, Chairman of the Board of
the Company, collectively will beneficially own approximately  % ( % if the
Underwriters' over-allotment option is exercised in full) of the voting power
of all outstanding shares of Common Stock by virtue of their beneficial
ownership of all outstanding shares of Class B Common Stock. As a result, such
stockholders will be able to control the outcome of virtually all matters
requiring a stockholder vote, including the election of directors. In
addition, such ownership of Common Stock may have the effect of delaying or
preventing a change of control of the Company and may adversely affect the
voting and other rights of other stockholders. See "Management," "Certain
Transactions," "Principal and Selling Stockholders" and "Description of
Capital Stock."
 
INTERNATIONAL SALES
 
  Approximately 11% of the Company's fiscal 1997 sales were derived from
export sales to foreign markets. The Company markets its products and services
in certain foreign oil and gas producing areas and is, therefore, subject to
the risks customarily attendant to sales in foreign countries. These risks
include, among others, nationalization, restrictive actions by local
governments, changes in tariffs and the adoption of foreign or domestic laws
limiting exports to certain foreign countries, any of which could have a
material adverse effect on the Company's ability to market its products
internationally. To date, the Company has not experienced any significant
problems in foreign countries arising from local government actions or
political instability, but there is no assurance that such problems will not
arise in the future. The Company believes there is significant potential for
establishing service and supply centers in select foreign countries,
particularly in South America, and is evaluating establishing a distribution
network in certain of these countries. If the Company were to open and
maintain a service and supply center in a foreign country, it may more
directly face risks customarily encountered in doing business in foreign
countries, including risks of foreign currency fluctuations. See "Business--
Strategy."
 
GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS
 
  Many aspects of the Company's operations are affected by political
developments and are subject to both domestic and foreign governmental
regulations, including those relating to worker safety and the protection of
the environment. In addition, the Company depends on the demand for its
products from the energy industry and, therefore, is affected by changing
taxes, price controls and other laws and regulations relating to the energy
industry. The adoption of laws and regulations curtailing exploration and
development drilling for, or the transportation, processing and refining of,
oil and gas for economic or other policy reasons could have a material adverse
effect on the Company's business, financial condition or results of operations
by limiting demand for the Company's products. The Company cannot determine
the extent to which its future operations and earnings may be affected by new
legislation, new regulations or changes in existing regulations.
 
  Products sold by the Company can be used in applications by customers which
are affected by numerous federal, state and local environmental laws and
regulations. The technical requirements of these laws and regulations are
becoming increasingly expensive, complex and stringent. These laws may provide
for "strict liability" for damages to natural resources or threats to public
health and safety, rendering a party liable for environmental damage without
regard to negligence or fault on the part of such party. Sanctions for
 
                                      10
<PAGE>
 
noncompliance may include revocation of permits, corrective action orders,
administrative or civil penalties and criminal prosecution. Certain
environmental laws provide for joint and several strict liability for
remediation of spills and releases of hazardous substances. In addition,
companies may be subject to claims alleging personal injury or property damage
as a result of alleged exposure to hazardous substances, as well as damage to
natural resources. As a supplier of equipment utilized in petroleum and
industrial applications, the Company may have claims made against it as a
result of a failed or defective product which causes or contributes to
environmental damage that may have a material adverse effect on the Company's
business, financial condition or results of operations. See "Business--
Governmental Regulations."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon the completion of the Offering, the Company will have outstanding a
total of     shares of Class A Common Stock and     shares of Class B Common
Stock. Each share of Class B Common Stock may be converted into one share of
Class A Common Stock at any time at the election of the holder and will
automatically convert into Class A Common Stock upon transfer to a holder that
is not a member of the Ketchum Group. The Ketchum Group is defined in the
Company's Amended and Restated Certificate of Incorporation (the "Restated
Certificate of Incorporation") as Betty J. Ketchum and the lineal descendants
of Lewis B. Ketchum and Betty J. Ketchum (collectively, the "Ketchum Family"),
and any trusts, partnerships or other entities controlled by or for the
benefit of any member or members of the Ketchum Family. Of these outstanding
shares, the     shares of Class A Common Stock offered hereby (    shares if
the Underwriters' over-allotment option is exercised in full) will be freely
tradeable without restrictions or registration under the Securities Act of
1933, as amended (the "Securities Act"), by persons other than "affiliates" of
the Company, as defined under the Securities Act. The remaining     shares of
outstanding Class A Common Stock and all outstanding Class B Stock will be
restricted securities as that term is defined by Rule 144 as promulgated under
the Securities Act.
 
  Approximately     of the restricted shares of outstanding Class A Common
Stock and all of the restricted shares of outstanding Class B Common Stock
(assuming such shares are converted by the holders to Class A Common Stock)
will have been held for more than one year as of the date of this Prospectus
and will become eligible for sale 90 days after the closing of the Offering
subject to applicable conditions and limitations of Rule 144, including volume
limitations. In addition, a holder of     shares of Class A Common Stock has
the right, commencing two years following the consummation of the Offering, to
require the Company to register its shares for future sale at any time. The
current stockholders of the Company have agreed that they will not, directly
or indirectly, sell any shares of Common Stock for a period of 180 days from
the date of this Prospectus without the prior written consent of Morgan
Stanley & Co. Incorporated. Future sales of substantial amounts of Class A
Common Stock in the public market following the Offering or the availability
of such shares for sale could adversely affect the market price of the Class A
Common Stock. See "Shares Eligible for Future Sale," "Description of Capital
Stock--Registration Rights" and "Underwriters."
 
NO INTENTION TO PAY DIVIDENDS
 
  The Company currently intends to retain any earnings for the future
operation and development of its business and does not currently anticipate
paying any dividends in the foreseeable future. The Credit Facility restricts
the payment of dividends. See "Dividend Policy," "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources" and Notes to the Company's Consolidated Financial
Statements.
 
CERTAIN ANTI-TAKEOVER EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
  One of the effects of the Company's authorized but unissued shares of Class
A Common Stock, Class B Common Stock and undesignated preferred stock may be
to enable the Board of Directors to render more difficult or discourage an
attempt to obtain control of the Company by means of a merger, tender offer,
proxy contest or otherwise, and thereby protect the continuity of the
Company's management. The Company's Restated
 
                                      11
<PAGE>
 
Certificate of Incorporation grants the Board of Directors the broad power to
establish the rights and preferences of the authorized and unissued preferred
stock, one or more series of which could be issued entitling holders to vote
separately as a class on any proposed merger or consolidation, to convert
preferred stock into a larger number of shares of Class A Common Stock or
other securities, to demand redemption at a specified price under prescribed
circumstances related to a change in control or to exercise other rights
designed to impede a takeover. The issuance of shares of preferred stock
pursuant to the Board's authority described above may adversely affect the
rights of the holders of the Class A Common Stock. See "Description of Capital
Stock."
 
  In the event the Company were to issue shares of Class B Common Stock or
preferred stock, or take other corporate action, the effect of which would be
to nullify, restrict or disparately reduce the per share voting rights of the
holders of the Class A Common Stock, such action could lead to proceedings of
the New York Stock Exchange, Inc. to have the Class A Common Stock removed
from listing on the New York Stock Exchange (the "NYSE"). The delisting of the
Class A Common Stock by the NYSE would likely have a material adverse effect
on the market value of the Class A Common Stock.
 
ABSENCE OF PRIOR PUBLIC MARKET
 
  Prior to the Offering, there has been no public market for the Class A
Common Stock. The initial public offering price will be determined by
negotiation between the Company and the Underwriters and may not be indicative
of the price at which the Class A Common Stock will trade following the
completion of the Offering. See "Underwriters" for a discussion of the factors
to be considered in determining the initial public offering price. The
completion of the Offering provides no assurance that an active trading market
for the Class A Common Stock will develop or, if developed, that it will be
sustained. The market price of the Class A Common Stock could also be subject
to significant fluctuation and may be influenced by many factors, including
variations in results of operations, variations in oil and natural gas prices,
investor perceptions of the Company and the energy industry and general
economic and other conditions. The stock market has, on occasion, experienced
significant price and volume fluctuations that often have been unrelated or
disproportionate to the operating performance of the affected companies, and
such fluctuations could have a material adverse effect on the market price of
the Class A Common Stock. See "Underwriters."
 
DILUTION
 
  Purchasers of Class A Common Stock in the Offering will experience immediate
and substantial dilution in the net tangible book value of their stock of $
per share (assuming an initial public offering price of $   per share) . See
"Dilution."

                                  THE COMPANY
 
GENERAL
 
  Red Man was founded in 1976 by the late Lewis B. Ketchum, a member and
former Chief of the Delaware Indian Tribe headquartered in Oklahoma. The
heritage and tradition of the Delaware Indian was very important to Mr.
Ketchum and was the basis upon which he gave the Company the name "Red Man."
Mr. Ketchum had over nineteen years of experience in the oilfield supply
industry prior to founding the Company. Mr. Ketchum was committed to the
concept of growth through quality and service. After his death in 1995, Mr.
Ketchum was succeeded by his son, L. Craig Ketchum, current Chief Executive
Officer and President, and his wife, Betty J. Ketchum, Chairman of the Board,
both of whom had worked with Mr. Ketchum since the Company's earliest stages.
 
  The Company began operations in 1977 as a distributor of tubular goods for
United States Steel Corporation (now USX Corporation) and Lone Star Steel
Company and it subsequently opened one oilfield service and supply center in
Oklahoma. By March 1987, the Company had opened three additional service and
supply centers in Texas, Louisiana and California. In March 1987, the Company
acquired 22 supply centers from Superior Supply Company. Of these 22 supply
centers, eight were consolidated into existing Company operations or were
subsequently sold. This acquisition provided the Company with additional
geographic coverage in Alabama, Kansas, New Mexico and Utah and significantly
increased the Company's ability to service major petroleum companies.
 
  From 1988 to 1990, the Company made additional strategic acquisitions of
seven supply center locations (net after consolidations) in Mississippi, New
Mexico, Oklahoma and Texas and related equipment and inventory items which
further strengthened the Company's geographic coverage and competitive
position.
 
  In April 1995, the Company diversified its business operations with the
acquisition of the assets of nine supply center locations of the supply
division of Vinson Supply Company (the "Vinson Acquisition"). These supply
centers primarily provided PVF industrial supplies for the downstream
refining, processing and chemical operations of the energy industry and
serviced major projects through competitive bidding. The Vinson Acquisition
positioned the Company to service upstream, midstream and downstream customers
and provide "one stop" shopping for its major integrated customers and
enhanced its geographic coverage in the major hydrocarbon producing and
refining regions of the United States.
 
  The Company is incorporated in Oklahoma. The Company's principal executive
offices are located at 8023 East 63rd Place, Tulsa, Oklahoma 74133, and its
telephone number is (918) 250-8541.
 
RECLASSIFICATION AND STOCK SPLIT
 
  The Company's Certificate of Incorporation was amended and restated in
December 1997 to increase and reclassify the Company's authorized Common Stock
from 500,000 shares of Class A Common Stock, par value $1.00 per share, having
one vote per share and 500,000 shares of non-voting Class B Common Stock, par
value $1.00 per share, to 50,000,000 shares of Class A Common Stock, par value
$.01 per share, having one vote per share and 50,000,000 shares of Class B
Common Stock, par value $.01 per share, having ten votes per share,
respectively. Simultaneously therewith, certain stockholders effected an
exchange of Common Stock which, after giving effect to a   -for-one stock
split of the Class A and Class B Common Stock effected January  , 1998, has
resulted in     shares of Class A Common Stock and     shares of Class B
Common Stock being outstanding at the date of this Prospectus. As a result of
the foregoing, L. Craig Ketchum, Chief Executive Officer and President of the
Company, and Betty J. Ketchum, Chairman of the Board of the Company,
collectively beneficially own all of the outstanding shares of Class B Common
Stock and, upon completion of the Offering, will beneficially own
approximately  % ( % if the Underwriters' over-allotment option is exercised
in full) of the voting power of all outstanding shares of Common Stock. See
"Management," "Principal and Selling Stockholders" and "Description of Capital
Stock."

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the Offering, assuming an initial
public offering price of $   per share and after deducting underwriting
discounts, commissions and estimated expenses, are estimated to be
approximately $   million ($   million if the Underwriters' over-allotment
option is exercised in full). The Company intends to use the net proceeds to
repay approximately $       of the Company's outstanding indebtedness under
the Credit Facility and redeem all the outstanding shares of Class C Preferred
Stock held by Consolidated Investment Services, Inc. ("Consolidated"), for the
face amount of $5.0 million, plus accrued dividends of $  . The Company will
not receive any of the net proceeds from the sale of Class A Common Stock by
the Selling Stockholder.
 
  The Credit Facility terminates on October 31, 2000, subject to an automatic
one-year renewal. At October 31, 1997, $81.4 million was outstanding under the
Credit Facility, $10.0 million of which was outstanding under the term loan
(the "Term Loan") portion of the Credit Facility and $71.4 million of which is
outstanding under the revolving credit (the "Line of Credit") portion of the
Credit Facility. The Line of Credit bears interest at LIBOR plus a margin
based on a trailing 12-month calculation of EBITDA as defined in the Credit
Agreement (7.25% at October 31, 1997), and the Term Loan bears interest at the
interest rate on the Line of Credit plus .25%. The Company intends to repay
all of the Term Loan with the net proceeds to the Company from the Offering
and to reduce the Line of Credit by approximately $   million. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
  The Company issued the 2,000 outstanding shares of Class C Preferred Stock
in connection with the financing of the Vinson Acquisition. The Class C
Preferred Stock bears an annual cumulative dividend of 5%, payable quarterly,
and the dividends paid on Class C Preferred Stock during fiscal 1997 totaled
$250,000. The Class C Preferred Stock is non-voting and subordinate to
indebtedness of the Company, but bears full preference to the Common Stock as
to dividends and to redemption in the event of liquidation of the Company. The
Class C Preferred Stock is subject to mandatory redemption on March 31, 2000.
See "Certain Transactions."
 
                                DIVIDEND POLICY
 
  The Company currently intends to retain any earnings for the future
operation and development of its business and does not intend to pay cash
dividends on its Common Stock in the foreseeable future. The Board of
Directors will review this policy on a regular basis in light of the Company's
earnings, financial condition and market opportunities. The Credit Facility
restricts the payment of dividends on Common Stock. The holders of the
Company's issued and outstanding Class C Preferred Stock have received annual
dividends of $250,000 as required by the privileges designated to the Class C
Preferred Stock. However, the Company will utilize a portion of the net
proceeds to the Company from the Offering to redeem all outstanding Class C
Preferred Stock. See "Use of Proceeds," "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources" and "Description of Capital Stock."

                                   DILUTION
 
  As of October 31, 1997, the net tangible book value of the Company was
approximately $23.0 million, or approximately $   per share of Common Stock.
Net tangible book value per share represents the amount of the Company's
tangible book value (total book value of tangible assets less total
liabilities and redeemable preferred stock) divided by the total number of
shares of Common Stock outstanding. After giving effect to the Offering
(assuming an initial public offering price of $   per share and no exercise of
the Underwriters' over-allotment option), the pro forma net tangible book
value of the Common Stock outstanding at October 31, 1997, would have been $
per share, representing an immediate increase in net tangible book value of
$   per share to current stockholders and an immediate dilution of $   per
share (the difference between the assumed initial public offering price and
the net tangible book value per share after the Offering) to persons
purchasing Class A Common Stock at the assumed initial public offering price.
The following table illustrates such per share dilution:

  The following table sets forth, on a pro forma basis as of October 31, 1997,
differences between the number of shares of Class A Common Stock acquired from

(1) EBITDA, or "earnings from continuing operations before interest expense,
    interest income, other (net), income taxes, depreciation and
    amortization," is not a generally accepted accounting principle measure,
    but is a supplemental financial measurement used by the Company in the
    evaluation of its business. EBITDA should not be construed as an
    alternative to net income or to cash flow from operations or any other
    measure of performance in accordance with generally accepted accounting
    principles, and is presented solely as a supplemental disclosure. EBITDA
    is a supplemental financial measure commonly used by investors in the oil
    services industry and is being presented in this Prospectus because
    management believes that EBITDA provides supplemental information about
    the Company's ability to meet its future requirements for debt service,
    capital expenditures and working capital. Management utilizes EBITDA to
    aid it in assessing the financial performance of the Company. Because
    EBITDA excludes some, but not all, items that affect net income and this
    measure may vary among companies, the EBITDA data presented above may not
    be comparable to similarly titled measures of other companies.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following information should be read in conjunction with the Company's
Consolidated Financial Statements and the related Notes thereto included
elsewhere in this Prospectus.
 
OVERVIEW
 
  Red Man is a leading distributor of products and services to the energy
industry. The Company distributes more than 55,000 products and tubular goods
through 42 service and supply centers and 11 sales locations strategically
located close to major hydrocarbon producing and refining areas of the United
States. In addition, through its membership in an association of distributors
with distribution centers in 35 states, the Company participates in certain
national accounts with other members. Due to the breadth of its products and
services, the Company is able to serve the needs of companies in the upstream,
midstream and downstream sectors of the energy industry.
 
  The market for equipment, supplies and services used by energy companies is
driven primarily by the industry fundamentals affecting such companies. These
fundamentals have been improving in recent years, due in part to favorable oil
and gas prices. The key factors affecting the industry include (i) demand for
and supply of oil and natural gas, (ii) capital expenditures by upstream,
midstream and downstream energy companies, (iii) trends toward increased
outsourcing and formation of alliances, and (iv) consolidation of supply and
service companies.
 
  Sales. The Company sells various products, including oil country tubular
goods, line pipe, valves, fittings and flanges, pumps, production equipment,
gas measurement equipment and hand tools. Sales are recorded as products are
shipped or accepted by the customer.
 
  Sales of OCTG are derived either from shipments out of Company-owned
inventories maintained in strategically located storage yards or from
shipments directly from mill sources. The significant majority of OCTG sales
come from shipments out of these storage yards. There are two types of sales
transactions out of Company-owned inventories: "stocking program" sales and
"spot" sales. The Company believes the majority of its OCTG sales is derived
from stocking program arrangements. The Company enters into stocking program
arrangements with customers to provide various specifications of OCTG at an
agreed upon price generally covering a time-frame from three to 18 months. The
Company procures OCTG from its mill sources and agrees to stock the OCTG in a
designated area close to the exploration and development drilling operations
of the end-user customer. As OCTG is needed by the customer, the Company will
arrange for the delivery of the OCTG to the customer's designated location.
The other OCTG sales out of Company-owned inventories are derived from spot
sales into the market. These transactions typically are the result of the
Company's success in securing orders from customers who have sent the Company
"requests for quotation" for small quantities of OCTG needed for a single well
or for a small drilling program. The critical factors for success in obtaining
these orders are price and availability.
 
  Sales of line pipe are derived either from shipments out of Company-owned
inventories maintained in strategically located storage yards or shipments
directly from mill sources. Line pipe sales are generally split equally
between shipments out of Company-owned inventories and direct mill shipments.
The majority of the line pipe sales is derived from spot sales into the
market, a significant portion of which is sold through the Company's
42 service and supply centers. These centers are strategically located close
to major hydrocarbon producing and refining areas of the United States. The
critical factors for success in obtaining these orders are price and
availability.
 
  Sales of other products come primarily from sales through the Company's 42
service and supply centers. A significant amount of these sales is derived
from alliance relationships, blanket contracts and MRO pricing agreements. A
majority of these sales is based upon pre-determined pricing utilizing
manufacturers' list prices less discounts off of the list price. Sales are
also derived from spot sales of products through the quotation process.
 
                                      18
<PAGE>
 
  Approximately 11% of the Company's fiscal 1997 sales were derived from
products shipped from domestic locations to foreign markets. The Company is
evaluating establishing a distribution network in South America through the
opening of service and supply centers. The Company believes that there is
significant potential for increased sales through the establishment of
distribution operations in select foreign countries.
 
  Cost of Products Sold. The Company's cost of products sold represents the
amounts paid to various suppliers including manufacturers, pipe coaters and
threaders, third-party inspectors and freight haulers. The Company attempts to
pass on supplier price increases to its customers. Margins on sales vary
between periods primarily due to variances in the mix of products sold.
Historically, margins on sales of OCTG have been lower than margins obtained
from the sales of other products and services.
 
  Selling, General and Administrative Expenses. The Company's selling, general
and administrative expenses include all employee, marketing, sales,
warehousing, other distribution costs, other related administrative functions
and general corporate expenses. Historically, selling, general and
administrative expenses relating to the Company's tubular goods sales have
been relatively fixed in nature and have not varied significantly with the
level of tubular goods sales. Conversely, selling, general and administrative
expenses relating to the Company's service and supply center operations have
been more variable in nature and increase or decrease as sales from service
and supply centers increase or decrease.

  YEAR ENDED OCTOBER 31, 1997, COMPARED TO YEAR ENDED OCTOBER 31, 1996
 
  Sales. Sales increased 30.4% to $454.4 million in fiscal 1997 from $348.4
million in fiscal 1996. This increase was due to a 60.7% increase in sales of
OCTG and an 18.3% increase in sales of oilfield supplies and industrial
products, including MRO and PVF items. The increase in sales was primarily the
result of an increase in the volume of products sold. Activities in the
upstream, midstream and downstream sectors of the energy industry continued to
increase, which resulted in continued strong demand for the Company's products
and services.
 
  Cost of Products Sold. The cost of products sold increased 30.9% to $403.8
million in fiscal 1997 from $308.3 million in fiscal 1996. The increase in
cost of products sold was due primarily to the increase in sales volumes. The
cost of products sold as a percentage of sales increased to 88.9% in fiscal
1997 from 88.5% in fiscal 1996. This increase is due primarily to an increase
in OCTG sales as a percentage of sales in fiscal 1997 as compared to fiscal
1996, resulting in slightly lower margins.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 14.6% to $34.3 million in fiscal 1997 from
$29.9 million in fiscal 1996 primarily as a result of the increase in sales.
As a percentage of sales, these expenses decreased to 7.5% in fiscal 1997 from
8.6% in fiscal 1996. The decrease in selling, general and administrative
expenses as a percentage of sales resulted primarily because
 
                                      19
<PAGE>
 
OCTG sales as a percentage of sales were larger in fiscal 1997 as compared
with fiscal 1996. Additionally, selling, general and administrative expenses
in relation to sales in the oilfield and industrial store operations decreased
due primarily to increased quantities of supplies and products sold through
more efficiently run operations.
 
  Operating Income. Operating income increased 60.7% to $16.4 million in
fiscal 1997 from $10.2 million in fiscal 1996 primarily as a result of the
fiscal 1997 increase in sales and the decrease in selling, general and
administrative expenses as a percentage of sales. Operating income as a
percentage of sales increased to 3.6% in fiscal 1997 from 2.9% in fiscal 1996.
 
  Interest Expense. Interest expense increased 16.6% to $5.6 million in fiscal
1997 from $4.8 million in fiscal 1996. The increase was primarily attributable
to increased borrowings due to increased working capital levels needed to
support the overall increase in sales. This increase was partially offset by a
decrease in the effective borrowing rates on the Company's Credit Facility.
Interest expense as a percentage of sales decreased to 1.2% in fiscal 1997
from 1.4% in fiscal 1996.
 
  Income Tax Expense. Income tax expense increased to $4.4 million in fiscal
1997 from $2.1 million in fiscal 1996. The Company's effective tax rate was
38.1% for fiscal 1997 compared to an effective tax rate of 38.9% for fiscal
1996.
 
  YEAR ENDED OCTOBER 31, 1996, COMPARED TO YEAR ENDED OCTOBER 31, 1995
 
  Sales. Sales increased 38.3% to $348.4 million in fiscal 1996 from $251.9
million in fiscal 1995. This increase was due primarily to the Vinson
Acquisition which was consummated in April 1995. Also, overall activities in
the upstream and midstream sectors of the oil and gas business increased which
resulted in continued strong demand for the Company's products and services.
 
  Cost of Products Sold. The cost of products sold increased 37.8% to $308.3
million in fiscal 1996 from $223.8 million in fiscal 1995. The increase in
cost of products sold was due to the increase in sales. The cost of products
sold as a percentage of sales in fiscal 1996 was 88.5% compared to 88.8% in
fiscal 1995. The cost of products sold as a percentage of sales remained
relatively constant due to the relative stability of the mix of products sold.
 
  Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 34.4% to $29.9 million in fiscal 1996 from
$22.3 million in fiscal 1995 primarily as a result of the increase in sales.
Selling, general and administrative expenses decreased as a percentage of
sales to 8.6% in fiscal 1996 from 8.8% in fiscal 1995. The decrease in
selling, general and administrative expenses as a percentage of sales resulted
primarily from productivity and efficiency gains in administrative functions
and general corporate expenses.
 
  Operating Income. Operating income increased 74.2% to $10.2 million in
fiscal 1996 from $5.9 million in fiscal 1995 primarily as a result of the
fiscal 1996 increase in sales, the slight decrease in cost of products sold as
a percentage of sales and the decrease in selling, general and administrative
expenses as a percentage of sales. Operating income as a percentage of sales
increased to 2.9% in fiscal 1996 from 2.3% in fiscal 1995.
 
  Interest Expense. Interest expense increased 33.4% to $4.8 million in fiscal
1996 from $3.6 million in fiscal 1995. The increase was primarily attributable
to increased borrowings incurred in connection with the Vinson Acquisition, as
well as increased working capital levels needed to support the overall
increase in sales to the upstream and midstream sectors of the oil and gas
business. Interest expense as a percentage of sales remained steady at 1.4% in
fiscal 1996 and fiscal 1995.
 
  Income Tax Expense. Income tax expense increased to $2.1 million in fiscal
1996 from $1.0 million in fiscal 1995. This increase was primarily
attributable to the Company's greater pretax profit level in fiscal 1996. The
Company's effective tax rate of 38.9% in fiscal 1996 increased from the
effective rate of 34.5% in fiscal 1995 primarily because of nontaxable
proceeds received by the Company in fiscal 1995 from a life insurance policy
related to the death of Lewis B. Ketchum, the Company's former Chief Executive
Officer.

LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's primary needs for funds are to support working capital
requirements and, to a lesser extent, capital expenditures for information
systems, service and supply center facilities and equipment. Historically, the
Company has met its funding needs with cash flows from operations and
borrowings under the Credit Facility.
 
  Because the Company is in the distribution business, significant components
of the Company's assets are accounts receivable and inventories, which
historically have been financed with borrowings under the Credit Facility.
Generally, as the Company's operations expand and sales increase, long-term
borrowings under the Credit Facility will increase to finance the cash
utilized by the Company's operating activities. During fiscal 1995, 1996 and
1997, net cash used in operating activities was $14.7 million, $6.6 million
and $21.8 million, respectively. However, cash flows from operations before
changes in working capital was $2.4 million, $4.7 million and $8.4 million,
respectively, during the same periods. The Company is focusing its attention
on the continued improvement of these major assets. Accounts receivable are
managed through conservative credit granting guidelines and continual
monitoring of customer payment habits. Inventories are managed through various
inventory management procedures, including returning items to manufacturers,
transfers between Company locations, consolidations of product lines,
participation in customer planning requirements and improved replenishment
techniques with Company suppliers. During fiscal 1995, 1996 and 1997, the
average days sales outstanding of accounts receivable was 40.3, 43.6 and 40.6,
respectively, and the Company's inventory turnover was 2.5, 2.5 and 2.8 times,
respectively.
 
  Net cash used in investing activities was $14.7 million, $2.2 million and
$.5 million in fiscal 1995, 1996 and 1997, respectively. Capital expenditures
were $.3 million, $2.4 million and $2.7 million in fiscal 1995, 1996 and 1997,
respectively. These expenditures were primarily for information systems
requirements, service and supply center facilities, furniture, fixtures and
certain equipment. Of the $14.7 million cash used in fiscal 1995, $14.5
million was attributable to the Vinson Acquisition. The Company does not
anticipate significant capital expenditures over the next few years. The
expenditures that are anticipated will be of the same nature as those in
fiscal 1996 and 1997 as described above unless the Company participates in
another acquisition. The Company does not anticipate any material expenditures
being required to ensure its information systems do not encounter future
problems processing information in the year 2000.
 
  Net cash provided by financing activities was $28.8 million, $9.3 million,
and $22.9 million in fiscal 1995, 1996 and 1997, respectively. The cash
provided by these financing activities was almost exclusively obtained through
increased borrowings under the Credit Facility.
 
  The Credit Facility consists of both the Line of Credit and the Term Loan.
The Company is permitted to borrow under the Line of Credit amounts up to the
lesser of (i) $100.0 million less the outstanding principal balance of the
Term Loan or (ii) an amount equal to the borrowing base amount. The borrowing
base amount is determined through a computation of eligible accounts
receivable and inventories as defined in the Credit Facility. At October 31,
1997, the amount of borrowings available under the Credit Facility was $18.6
million. The Company pays a fee on the unused portion of the Line of Credit
equal to .375% per year. Following the Offering, the Company intends to
renegotiate the terms of the Credit Facility, including possibly reducing the
size of the facility.
 
  The Company intends to use the net proceeds to the Company from the Offering
to repay approximately $    of its outstanding indebtedness under the Credit
Facility and redeem the Class C Preferred Stock at its par value of $5.0
million, plus accrued dividends of $   . The Company believes that internally
generated cash from operations and availability under the Credit Facility will
be sufficient to finance the projected cash requirements of its current and
future operations over the next twelve months. The Company is continually
reviewing potential acquisitions in its markets. Depending upon the size,
nature and timing of an acquisition, the Company could require additional
capital in the form of either debt or equity.
 
                                      21
<PAGE>
 
IMPACT OF INFLATION
 
  Inflation has not had a significant effect on the Company's operating
results or financial condition in recent years. Management believes that price
increases from its various suppliers of products can generally be passed on to
its customers.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS No.
128"). SFAS No. 128 will change the computation, presentation and disclosure
requirements for earnings per share. This pronouncement requires the
presentation of "basic" and "diluted" earnings per share. This statement is
effective for financial statements issued for periods ending after December
15, 1997, including interim periods, and requires restatement of all prior
period earnings per share amounts. The Company will adopt SFAS No. 128 in the
second quarter of fiscal 1998; however, this pronouncement is not expected to
have a material effect on its earnings per share when adopted.

                                   BUSINESS
 
GENERAL
 
  Red Man is a leading distributor of products and services to the energy
industry. The Company distributes more than 55,000 products and tubular goods
through 42 service and supply centers and 11 sales locations strategically
located close to major hydrocarbon producing and refining areas of the United
States. In addition, through its membership in an association of distributors
with distribution centers in 35 states, the Company participates in certain
national accounts with other members. Due to the breadth of its products and
services, Red Man is able to serve the needs of companies in the upstream,
midstream and downstream sectors of the energy industry. The Company believes
it is one of only two companies that can provide products and services to
customers engaged in upstream-to-downstream operations in major hydrocarbon
producing and refining areas of the United States.
 
  The Company's operations involve the distribution of tubular goods,
including OCTG and line pipe, and the operation of service and supply centers
which distribute MRO products utilized in the energy industry, as well as
industrial products consisting primarily of line pipe, valves, fittings and
flanges. In fiscal 1997, sales of tubular goods represented approximately 55%
of total sales, and sales of other products from service and supply centers
represented approximately 45% of total sales.
 
  The Company distributes a broad range of OCTG and line pipe for oilfield and
industrial applications. The Company purchases OCTG and line pipe manufactured
by 23 domestic mills and four foreign mills and distributes these products
directly from the mills or from the Company's own inventory maintained in
storage yards strategically located throughout major hydrocarbon producing
regions of the United States. A significant portion of the Company's tubular
goods sales is made pursuant to stocking program arrangements with customers.
Under such arrangements, the Company provides various specifications of
tubular goods at an agreed upon price generally for a period from three to 18
months.
 
  The Company's oilfield and industrial service and supply centers provide MRO
and PVF products and various related services to the upstream, midstream and
downstream operations of the energy industry, as well as to engineering and
construction companies, fabricators, drilling contractors, utilities,
processing plants and energy industry service companies. In addition, the
Company markets gas measurement products, consisting of meter tubes and skid-
mounted meter stations, and distributes measurement-related products and
services from its various service and supply centers.
 
  As major integrated and large independent oil and gas companies have begun
implementing cost-cutting and efficiency initiatives to focus on their core
business activities, many of these companies have begun outsourcing their
procurement and inventory management requirements. In response to these
initiatives, the Company provides a number of value added services, including
inventory procurement and management, warehouse management, integrated supply
arrangements, management information reporting and total project management.
These value added services are designed to enable the Company's customers to
operate more efficiently by reducing their total procurement costs and the
number of suppliers utilized.
 
  In addition, a number of major integrated and large independent oil and gas
companies are seeking strategic alliances with their suppliers and service
providers to establish service programs which enhance operating efficiencies.
The Company has developed and is actively pursuing strategic alliances with
its customers whereby a number of the Company's value added services may be
combined as needed to enable these customers to operate more efficiently. Red
Man also benefits from these alliances due to the longer term relationships
created. These relationships generally provide greater consistency and
predictability with respect to customer procurement requirements, improved
utilization of assets and increased inventory turnover. The Company initially
developed alliances to meet the needs of the upstream operations of its major
integrated and large independent oil and gas companies. However, the Company
has expanded certain of these alliances to provide products and services to
the midstream and downstream operations of its integrated customers. The
Company's major customers with which it has strategic alliances include Amoco
Production Company, Chevron USA, Inc.,
 
                                      23
<PAGE>
 
Coastal Management Corporation, Exxon Company, U.S.A., Mobil Oil Corporation,
OXY USA, Inc., Phillips Petroleum Company, Shell Offshore Inc., Texaco, Inc.,
The Williams Companies, Inc. and Union Pacific Resources Group, Inc. In
addition, the Company has commenced developing strategic alliances with
industrial customers, including Kaiser Aluminum & Chemical Corporation. The
Company considers its efforts to obtain strategic alliances with customers to
be of major importance to its future growth.
 
  The Company has grown its business operations both through acquisitions and
internal expansion. Sales have grown at a 25.3% compounded annual growth rate
from $184.2 million in fiscal 1993 to $454.4 million in fiscal 1997. Net
income has grown over the same period at a 39.0% compounded annual growth rate
from $1.9 million to $7.1 million.
 
  The Company believes it is well positioned to continue as a leading
distributor of products and services to the energy industry. The Company
considers its competitive strengths to include the following:
 
 . Business and Geographical Diversification. The Company provides products and
  services to customers involved in the upstream, midstream and downstream
  operations of the energy industry. Accordingly, the Company can provide "one
  stop" shopping for its integrated customers while reducing its dependence on
  the exploration and production activities of oil and gas companies. In
  addition, the Company's 42 service and supply centers are located near major
  hydrocarbon and refining regions in the United States, which enhances the
  Company's ability to respond to customers quickly and reduces its dependence
  on the level of activity in any one region. Further, management of these
  centers is decentralized so that the Company can tailor its products and
  services to meet the specific needs and requirements of its customers in
  each location.
 
 . Value Added Services. The Company is a leader in providing comprehensive and
  innovative services to its customers, including inventory procurement and
  management, warehouse management, integrated supply arrangements, management
  information reporting and total project management. The Company has also
  developed significant long-term strategic alliances with certain of its
  customers whereby the Company may provide a combination of these services to
  enable its customers to operate more efficiently and reduce costs.
 
 . Relationships with Customers. Due to management's commitment to service, the
  Company has developed long-term relationships with a high quality customer
  base. These customers include major integrated and large independent oil and
  gas companies, as well as significant industrial companies. The Company
  believes it has generally been able to increase sales as its customers'
  operations have grown and increase its market share for certain products.
  The Company's ability to increase its sales and market share is due, in
  part, to its ability to provide a range of innovative, value added services
  in addition to quality equipment, supplies and products.
 
 . Experienced and Incentivized Management Team. The Company's senior
  management team has an average of 26 years experience in the oilfield and
  industrial supply business. After the completion of the Offering, certain
  officers of the Company will beneficially own all of the outstanding shares
  of Class B Common Stock and the Company's Employee Stock Ownership Plan will
  own   % of the outstanding shares of Class A Common Stock ( % if the
  Underwriters' over-allotment option is exercised in full).
 
 . Relationships with Mills and Suppliers. By virtue of being a leading
  distributor of oilfield tubular goods and MRO products, the Company believes
  it has developed excellent relationships with its domestic mill and MRO
  suppliers. The Company believes these relationships are crucial in order for
  it to quickly respond to the specific requirements of its customers. For
  fiscal 1997, the Company believes it was a leading distributor of tubular
  goods manufactured by CF&I Steel, Inc., Lone Star Steel Company and the
  U.S. Steel Group of USX Corporation.
 
 . Ability to Manage Growth and Integrate Acquisitions. Over the last ten
  years, the Company has acquired a total of 42 service and supply centers
  through five acquisitions. Seventeen of these service and supply centers
  were either subsequently consolidated with the Company's existing locations,
  sold or closed. In addition, pursuant to its internal growth plans the
  Company has opened 13 new service and supply centers over the
 
                                      24
<PAGE>
 
  same period. The Company believes its historical results of operations
  reflect its ability to carefully plan and manage its growth and successfully
  integrate the operations of acquired service and supply centers.
 
INDUSTRY OVERVIEW
 
  The market for equipment, supplies and services used by energy companies is
driven primarily by the industry fundamentals affecting such companies. These
fundamentals have been improving in recent years, due in part to favorable oil
and gas prices. The key factors affecting the industry include (i) demand for
and supply of oil and natural gas, (ii) capital expenditures by upstream,
midstream and downstream energy companies, (iii) trends toward increased
outsourcing and formation of alliances, and (iv) consolidation of supply and
service companies.
 
  Primary energy consumption in the United States from 1990 to 1995 has
outpaced production of crude oil and natural gas. During this period, oil
consumption increased from 16.3 million barrels of oil per day ("MMBPD") to
16.9 MMBPD, an annual growth rate of approximately .8%, compared to a decline
in production from 7.4 MMBPD to 6.6 MMBPD. Similarly, consumption of natural
gas increased from 51.3 billion cubic feet per day ("BCFD") to 59.3 BCFD, an
annual growth rate of approximately 3.0%, compared to an increase in natural
gas production from 49.5 BCFD to 53.8 BCFD, an annual growth rate of
approximately 1.7%. This has led to a significant increase in drilling
activity which has resulted in increased demand for oilfield equipment,
supplies and services. Since reaching a low of 718 in 1992, the U.S. average
rig count increased to 779 in 1996 and was in excess of 1,000 as of November
1997. Similarly, rig utilization rates increased from 59.7% in 1992 to 76.6%
in 1996 and were approximately 86.9% as of July 1997. Further, demand for
oilfield equipment, supplies and services has been favorably affected by the
trend toward drilling deeper wells, as shallow deposits have largely been
found and depleted. Deeper wells typically require more oilfield equipment,
supplies and services than shallow wells.
 
  In addition to basic supply and demand fundamentals, technological advances
in exploration, development and production techniques have contributed to
increased activity by oil and gas companies. These techniques, including new
seismic data collection (3D/4D seismic) and drilling (deviated, horizontal and
multilateral wells) methods, have lowered the cost of exploration and
development and have increased demand for supplies and services in many phases
of a hydrocarbon field's development. As hydrocarbon basins mature, the need
increases for artificial lift, secondary and tertiary recovery methods to
extend the production life of such basins. The Company believes this trend is
further benefiting the demand for oilfield equipment, supplies and services.
 
  Capital expenditures by energy companies have been increasing in recent
years. Exploration and production companies are increasing capital
expenditures as they focus on increasing reserves and production to meet
increased demand. Midstream companies are spending money to build gathering
facilities to connect new wells and gas gathering and natural gas liquids
plants to process the increased production. Downstream companies are focusing
their capital expenditures on increasing the productivity and yield of
refineries and chemical plants and on meeting increasingly stringent
environmental requirements. Drilling, exploration and production spending
increased from $16.0 billion in 1990 to $16.7 billion in 1996 and is projected
to continue to grow. Capital expenditures by downstream companies have grown
from $10.2 billion in 1990 to $10.6 billion in 1996.
 
  In the past decade, the energy industry has undergone a period of
restructuring and rationalization in response to low margins, cost
inefficiencies and poor returns. Many energy companies have been redefining
the core areas of their businesses and have downsized their organizations to
concentrate their resources, maximize returns from existing assets and focus
on finding and developing new reserves. As a result, energy companies are
increasingly outsourcing responsibility for certain activities, including
inventory procurement, management and reporting requirements. In addition,
energy companies are moving away from individual contracts with a variety of
separate suppliers of equipment and services, all coordinated and managed by
the buyer, to a limited number of more cooperative arrangements to improve
operating efficiencies. These new relationships, which include integrated
supply agreements, maintenance, repair and operating agreements, joint
ventures, partnerships and alliances, are being implemented as cost cutting
strategies to enhance productivity and reduce capital and
 
                                      25

operating costs. The trend of outsourcing and the formation of alliances has
created new opportunities for the equipment, supplies and service industry.
 
  The Company believes the oilfield and industrial equipment, supplies and
services industry in the United States is fragmented, with a few larger and
many smaller participants than the Company. The industry has undergone
consolidation due to the trend of energy companies towards reducing their
supplier base to focus on key suppliers who can service their requirements for
upstream, midstream and downstream operations and who have the broad product
line and financial resources to meet their needs in a number of geographic
regions. The Company believes this consolidation trend will continue and will
present opportunities to make strategic acquisitions.
 
STRATEGY
 
  The Company's goal is to expand its existing market position in the
upstream, midstream and downstream sectors of the energy industry, while at
the same time increasing its earnings and cash flow per share to enhance
overall stockholder value. Key elements of the Company's strategy for
achieving this goal are to:
 
 . Maintain and Grow Alliances. The Company has entered into and is seeking to
  enter into alliances to better serve its customers and enable these
  customers to operate more efficiently. The Company believes these alliances
  result in improved utilization of its assets due to the improved consistency
  and predictability of customer procurement requirements and increased
  profitability due to an expansion in the volume and range of products sold.
  In addition, these alliances often provide opportunities to supply
  additional products and services through the close working relationships
  developed. The Company plans to maintain and expand its alliances with major
  integrated and independent oil and gas companies and is also actively
  pursuing alliances with companies outside of the oil and gas industry. The
  Company believes it is well positioned to form alliances as a result of its
  (i) geographically diverse network of service and supply centers located in
  major hydrocarbon producing and refining areas of the United States, (ii)
  breadth of available product lines and value added services and (iii) strong
  relationships with customers, mills and suppliers.
 
 . Increase Maintenance, Repair and Operating Agreements. The Company has
  numerous MRO agreements in place, primarily with upstream customers. These
  agreements are generally non-exclusive contracts which provide a set price
  for certain of the Company's products which may be required by a customer.
  MRO agreements mutually benefit the customer and the Company by reducing the
  transaction costs associated with the submission of bids for each order. The
  Company believes there are additional opportunities to utilize MRO
  arrangements for servicing the requirements of its midstream and downstream
  customers and is actively pursuing such agreements.
 
 . Expand into Selected International Markets. The Company distributes its
  products to several foreign markets from certain domestic locations. The
  Company believes there is significant potential for establishing service and
  supply centers in select foreign countries, particularly in South America,
  and is evaluating establishing a distribution network in certain of these
  countries.
 
 . Develop Integrated Supply Arrangements. The Company has entered into and is
  pursuing integrated supply arrangements with certain of its customers. These
  arrangements generally designate the Company as the single source provider,
  either directly or indirectly, of the upstream, midstream and/or downstream
  requirements of customers. The Company believes these arrangements allow it
  to reduce the total costs to the customer and sell an increased volume of a
  broader range of products. The Company believes it is well positioned to
  obtain these arrangements due to its (i) geographically diverse network of
  service and supply centers, (ii) breadth of available product lines and
  value added services and (iii) strong relationships with customers, mills
  and suppliers.
 
 . Increase Tubular Goods Sales. The Company believes there exists an
  opportunity to expand its market position in the distribution of tubular
  goods, particularly with respect to line pipe. The Company believes that the
  strong demand for tubular goods experienced in fiscal 1997 will continue and
  that significant opportunities exist to grow this portion of the business,
  particularly line pipe sales to the midstream and
 
                                      26
<PAGE>
 
  downstream market. The Company believes that its (i) geographically diverse
  distribution network, (ii) favorable customer relationships, (iii) strong
  relationships with mills and (iv) purchasing leverage due to the volume of
  products sold favorably position the Company to capitalize on this
  opportunity.
 
 . Capitalize on Strong Balance Sheet. The Company plans to use the net
  proceeds to the Company from the Offering to repay indebtedness under the
  Credit Facility and redeem the outstanding shares of Class C Preferred
  Stock. The Company believes that its strong balance sheet will provide it
  with the financial flexibility to carry out its strategy to grow and develop
  new and existing markets both domestically and internationally. The Company
  intends to actively consider and pursue acquisition opportunities and
  evaluate opening new service and supply centers. Although the Company
  evaluates acquisition opportunities from time to time, it currently does not
  have any understanding, contract or agreement to acquire any business or
  assets.
 
PRODUCTS AND SERVICES
 
  TUBULAR GOODS
 
  The Company distributes a variety of widely used oil country tubular
products manufactured by third parties in diameters ranging in size from one-
inch tubing to 20-inch casing. OCTG primarily consists of well casing and
production tubing used in the drilling, completion and production of oil and
gas wells. Well casing is used to line walls of the well bore to provide
structural support. Production tubing provides the conduit through which the
oil or gas will be brought to the surface upon completion of the well.
 
  The Company maintains a broad range of line pipe products for oilfield and
industrial customers. Line pipe inventories include carbon steel, stainless
steel and coated pipe. Line pipe specifications range from one-eighth-inch
through 36-inch diameters, in seamless, continuous weld, electric weld and
double submerged arc weld and in a wide range of grades and wall thicknesses.
Line pipe is used to gather and transport oil and gas production from
producing well locations to gas processing plants, refineries, chemical plants
and storage facilities.
 
  Sales of OCTG are derived either from shipments out of Company-owned
inventories maintained in strategically located storage yards or from
shipments directly from mill sources. The significant majority of OCTG sales
come from shipments out of these storage yards. There are two types of sales
transactions out of Company-owned inventories: "stocking program" sales and
spot sales. The Company believes the majority of its OCTG sales is derived
from stocking program arrangements. The Company enters into stocking program
arrangements with customers to provide various specifications of OCTG at an
agreed upon price generally covering a time-frame from three to 18 months. The
Company procures OCTG from its mill sources and agrees to stock the OCTG in a
designated area close to the exploration and development drilling operations
of the end-user customer. As OCTG is needed by the customer, the Company will
arrange for the delivery of the OCTG to the customer's designated location.
The other OCTG sales out of Company-owned inventories are derived from "spot"
sales into the market. These transactions typically are the result of the
Company's success in securing orders from customers who have sent the Company
"requests for quotation" for small quantities of OCTG needed for a single well
or for a small drilling program.
 
  OCTG is stocked at over 64 third-party locations in grades ranging from J-55
to Q-125, threaded with American Petroleum Institute ("API") and premium
connections. The Company's inventory of line pipe is stored in 31 yards. A
majority of the line pipe is stored in five of the Company's service and
supply centers and the balance is maintained in independent yards.
 
  Substantially all of the Company's OCTG is marketed through the Company's
direct sales force operating out of 11 sales offices. Sales of line pipe are
made through the Company's direct sales force and through its 42 service and
supply centers. The Company believes its relationships with major domestic and
foreign mills
 
                                      27
<PAGE>
 
provide it with a competitive advantage in regard to pricing and availability
of tubular goods. The Company believes it is a leading distributor for CF&I
Steel, Inc., Lone Star Steel Company and the U.S. Steel Group of USX
Corporation. The majority of sales of tubular goods are to domestic companies.
 
  SERVICE AND SUPPLY CENTERS
 
  The Company's distribution network of 42 service and supply centers offer
55,000 products manufactured by over 7,000 manufacturers for distribution to
oilfield and industrial customers. Thirty-two service and supply centers are
located strategically in or near petroleum producing areas and through these
centers the Company concentrates sales and marketing efforts on MRO needs of
major petroleum exploration, production, refining and chemical companies. Ten
service and supply centers are strategically located near major refining and
other downstream operations areas and through these centers the Company
concentrates sales and marketing efforts on industrial supplies and product
needs of refineries, pipelines, chemical plants and fabricators.
 
  Each of the Company's service and supply centers offers a complete line of
MRO supplies as well as pipe, valves, fittings and flanges manufactured by
leading manufacturers in the industry. The supplies and equipment stocked at
the Company's service and supply centers vary by location depending on the
specific needs of the customers supported.
 
  Valves. Valves offered by the Company include ball, butterfly, gate, check
production, needle, plug and relief valves manufactured from cast steel,
stainless steel, forged steel, carbon steel or ductile iron. The Company
distributes valve products manufactured by more than 40 manufacturers. Valves
are generally used in oilfield and industrial applications to control
direction, velocity and pressure of liquids and gases within a transmission
line.
 
  Fittings. Fittings offered by the Company include welded carbon, welded
stainless, forged carbon, forged stainless, malleable and cast iron fittings,
manufactured by approximately 15 manufacturers. Fittings are generally
utilized to connect numerous arrays of piping configurations for hydrocarbon
transportation and processing.
 
  Flanges. Flanges offered by the Company include carbon and stainless steel
flanges manufactured by approximately eight manufacturers. Flanges are
utilized as spacers and sealers between connection points and valves on
transmission lines.
 
  The Company's service and supply centers generally employ from four to ten
persons, with larger centers employing up to 35 persons and the largest center
employing approximately 60 persons. Service and supply centers are
strategically located in major hydrocarbon and refining regions of the United
States which allows for short lead times between customer order and delivery.
In addition, each service and supply center is treated as an individual profit
center. Individual service and supply center managers are responsible for
certain management decisions, including product stocking decisions, marketing
and inventory control. The Company's service and supply centers generally are
available 24 hours a day, seven days a week, to serve the needs of its
petroleum and industrial customers. Each service and supply center will stock
specialty items at the request of the customer to provide "one stop" shopping
availability. The Company will also deliver its products directly to the field
locations of its customers.
 
  Since 1981, the Company has operated fabrication facilities in Tulsa,
Oklahoma, to fabricate and assemble quality gas measurement products. The
Company believes it is an industry leader in the fabrication of meter tubes,
skid-mounted meter runs and packaged measurement stations utilized for the
accurate measurement of natural gas flows. The Company offers a variety of
measurement accessories and custom piping products including bleed rings, flow
recorders, headers, hookup kits, manifolds, meter houses, orifice fittings,
orifice flanges and orifice plates.
 
  All meter tubes fabricated and assembled by the Company satisfy the
requirements of the latest American Gas Association ("AGA") and API standards.
Inventories maintained at the fabrication facility include Daniel
 
                                      28
<PAGE>
 
Simplex and senior orifice fittings, two-inch through eight-inch diameter
cold-drawn seamless meter tubing, new and reconditioned Barton flow recorders
and walk-in and line-type meter houses. The Company's measurement fabrication
facility currently includes 7,500 square feet of shop space and 20,000 square
feet of inventory storage area. In addition to a wide range of fabrication
equipment, the fabrication facility maintains a complete set of testing and
inspection tools to produce meter tubes to the latest AGA/API specifications.
 
  Sales of measurement products, which represent less than 5% of total sales,
have increased 200% from 1990 to 1997. Plans are currently being implemented
to relocate to a larger fabrication plant of more than 20,000 square feet
during the Spring of 1998 to increase the Company's capacity to produce larger
and more complex gas and liquid measurement packages.
 
  VALUE ADDED SERVICES
 
  As major integrated and large independent oil and gas companies have begun
implementing cost cutting and efficiency initiatives to focus on their core
business, many of these companies have begun outsourcing their procurement and
inventory management requirements. In response to these initiatives and to
satisfy customer service requirements, the Company provides a number of value
added services. These value added services include the following:
 
 . Inventory Procurement and Management. Inventory procurement and management
  services may range from procuring, storing and delivering products for
  customers, whereby the Company seeks to eliminate customers' need to
  maintain their own inventory storage facilities and related personnel, to
  entering into stocking program arrangements, whereby major integrated and
  large independent oil and gas companies will plan their OCTG and line pipe
  requirements and set up stocking programs for an entire year or until the
  completion of development programs for a major production or development
  area.
 
 . Warehouse Management. Warehouse management services generally provide for
  the Company's total operation of a customer's warehouse facility, including
  its related inventory, by providing personnel to work directly out of such
  facilities.
 
 . Integrated Supply Arrangements. Under integrated supply arrangements, the
  Company acts as the single source provider for all of the upstream,
  midstream and/or downstream requirements of its customers. In these
  arrangements, the Company coordinates the procurement of products for which
  it is the distributor as well as products provided by other suppliers.
 
 . Management Information Reporting. Management information reporting services
  include providing detailed product information reports, delivery and
  schedule reports, on-time reports and "score cards" to track customer
  savings resulting from services provided by the Company.
 
 . Total Project Management. The Company also provides total project management
  services whereby it will plan, schedule and stock the requirements of major
  projects of the Company's midstream and downstream customers.
 
CUSTOMERS
 
  The Company's principal customers are companies that actively participate in
the upstream, midstream and downstream sectors of the energy industry as well
as industrial companies.
 
  The Company is not dependent on any one customer or group of customers. In
fiscal 1997, the Company's top ten customers represented approximately 49% of
sales, with Chevron USA, Inc. accounting for approximately 12% of sales. The
number and variety of the Company's products required in a given year by any
one customer depends primarily upon that customer's capital expenditure budget
in any single year and on the results of competitive bids for major projects.
Consequently, a customer that accounts for a significant portion of sales in
one fiscal year may represent an immaterial portion of sales in subsequent
years.
 
  Due to the demanding operating conditions in the energy industry and high
costs associated with equipment failure, customers prefer highly reliable
products and vendors with established qualifications and experience. The
 
                                      29
<PAGE>
 
Company strives to build strong long-term relationships with its customers by
maintaining its reputation as a supplier of high-quality, efficient and
reliable products and by responding promptly to customer orders.
 
COMPETITION
 
  The oilfield and industrial distribution services business is highly
competitive. The primary competitive factors in the distribution of products
and services to the energy industry are price and the quality, breadth and
availability of products and services provided.
 
  The Company's sales and earnings can be affected by competitive actions such
as price changes, improved delivery and other actions by competitors. The
Company's principal competitors in the United States distribution services
industry include Continental Emsco Company, Dupre Supply Company, McJunkin
Corporation, National-Oilwell, Inc. and Wilson Supply Company. The Company
also competes with a number of regional or local oilfield supply stores in
each geographic market. The Company's North American OCTG distribution
business competes primarily with Bourland & Leverich, Inc., National-Oilwell,
Inc., Premier Pipe, Inc., Sooner Pipe and Supply Corp., Vinson Supply Company
and Wilson Supply Company. In sales of line pipe, the Company competes with
Dixie Pipe Sales, Inc., McJunkin Corporation, Texas Pipe and Tube Corp. and
Wilson Supply Company, as well as direct shipments from domestic mills.
Several of the Company's primary competitors are diversified multinational
companies with substantially larger operating staffs and greater capital
resources than those of the Company.
 
PROPERTIES
 
  The Company's principal office and headquarters is located in Tulsa,
Oklahoma, and consists of approximately 34,000 square feet of leased office
space. In addition, the Company owns or leases facilities at strategic
locations in ten states throughout the mid-southern, western and southwestern
United States. These facilities include 11 sales offices, 42 oilfield and
industrial service and supply centers and a single fabrication facility. Sales
offices are primarily responsible for the distribution of tubular goods,
whereas the service and supply centers maintain inventories of consumable
oilfield and industrial products and supplies and provide certain repair and
reworking services for down-hole pumps. See "Business--Products and Services."

Oklahoma, Texas and Utah.

  The total number of the Company's employees as of October 31, 1997 was 570,
all of which are located in the United States. Eighteen of the Company's
employees are covered by a collective bargaining agreement with the United
Steelworkers Union. This bargaining unit was in existence at one supply center
location acquired by the Company in the Vinson Acquisition. The Company
considers its employee relations to be good.
 
GOVERNMENTAL REGULATIONS
 
  Many aspects of the Company's operations are affected by political
developments and are subject to governmental regulations, including those
relating to oil field operations, worker safety and the protection of the
environment. In addition, the Company depends on the demand for its services
from the energy industry and, therefore, is affected by changing taxes, price
controls and other laws and regulations relating to the energy industry
generally, including those specifically directed to exploration, production,
transportation, processing and refining operations. The adoption of laws and
regulations curtailing exploration and development drilling for, or the
transportation, processing and refining of, oil and gas for economic or other
policy reasons could adversely affect the Company's operations by limiting
demand for the Company's products.
 
  Products sold by the Company can be used in applications by customers which
are affected by numerous federal, state and local environmental laws and
regulations. The technical requirements of these laws and regulations are
becoming increasingly expensive, complex and stringent. These laws may provide
for "strict liability" for damages to natural resources or threats to public
health and safety, rendering a party liable for the environmental damage
without regard to negligence or fault on the part of such party. Sanctions for
noncompliance may include revocation of permits, corrective action orders,
administrative or civil penalties and criminal prosecution. Certain
environmental laws provide for joint and several strict liability for
remediation of spills and releases of hazardous substances. In addition,
companies may be subject to claims alleging personal injury or property damage
as a result of alleged exposure to hazardous substances, as well as damage to
natural resources. As a supplier of equipment utilized in petroleum and
industrial applications, the Company may have claims made against it as a
result of a failure or defective product which causes or contributes to
environmental damage.
 
  Based on the Company's experience to date, the Company does not currently
anticipate any material adverse effect on its business or consolidated
financial position as a result of future compliance with existing
environmental laws and regulations controlling the discharge of materials into
the environment. However, future events, such as changes in existing laws and
regulations or their interpretation, more vigorous enforcement policies of
regulatory agencies or stricter or different interpretations of existing laws
and regulations, may require additional expenditures by the Company, which may
be material.
 
LEGAL PROCEEDINGS
 
  The Company is not a party to, nor is any of its property the subject of,
any pending legal proceedings that, in the opinion of management, are expected
to have a material adverse effect on the Company's business, financial
condition or results of operations.

initial members of both committees will be the Company's independent non-
employee directors who will be appointed to the Board of Directors after

results of procedures for internal auditing of the Company and the adequacy of
the Company's system of internal accounting controls. The Compensation
Committee will approve, or, in some cases, recommend to the Board,
remuneration arrangements and other compensation plans involving the Company's
directors, executive officers and certain other employees whose compensation

INCENTIVE PLAN
 
  General. The Company has established the Red Man Pipe & Supply Co. Incentive
Stock Plan (the "Incentive Plan"), the purpose of which is to provide those
persons selected to participate in such plan additional incentive to promote
the long-term success of Company, enable such persons to acquire an equity
interest in Company and enable Company to attract and retain individuals
instrumental in contributing to its success.
 
                                      34
<PAGE>
 
Officers, employees and directors are eligible to receive grants and awards
under the Incentive Plan. The total amount of Class A Common Stock initially
authorized and reserved for issuance under the Incentive Plan is     shares.
No awards have been granted under the Incentive Plan.
 
  The Incentive Plan is administered by the Board of Directors; provided,
however, that the Board of Directors may delegate any and all of its duties to
a committee of the Board of Directors (as used in this description of the
Incentive Plan, the "Committee"). The Company anticipates that the
Compensation Committee will administer the Incentive Plan following the
Offering except with respect to members of the Compensation Committee for
which the full Board of Directors will administer the Incentive Plan. In the
course of administering the Incentive Plan, the Committee is given broad
discretion to construe and interpret the Incentive Plan and to adopt such
rules, regulations, guidelines, subplans and procedures for carrying out the
Incentive Plan as it deems necessary. In addition, the Committee is authorized
to identify plan participants, determine the types and amounts of awards to be
granted, establish the terms, conditions and provisions of awards, prescribe
forms of award agreements, establish, amend and rescind rules and regulations
relating to the Incentive Plan.
 
  Summary of Awards. The Incentive Plan authorizes the grant of stock options
and award of restricted stock. Generally, awards under the Incentive Plan will
be granted for no consideration other than prior and future services. Stock
options granted to participants pursuant to the Incentive Plan may, at the
discretion of the Committee, be incentive stock options ("ISOs") within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), or non-qualified stock options. ISOs, however, may only be awarded to
employees of the Company. The exercise price of an ISO may not be less than
the fair market value of the Class A Common Stock on the date of grant (or
110% of such fair market value in the case of ISOs granted to employees who
own more than 10% of the combined voting power of all classes of stock of the
Company). In the case of non-qualified stock options, the exercise price shall
be as determined by the Committee in its sole discretion, except that such
price shall not be less than the fair market value of the Class A Common Stock
on the date of grant.
 
  Stock options granted under the Incentive Plan are exercisable in whole or
in part at such time or times as may be determined by the Committee, except
that ISOs may not be exercised after the expiration of ten years from the date
granted (or five years in the case of ISOs granted to employees who own more
than 10% of the combined voting power of all classes of stock of the Company).
Generally, stock options may be exercised by the payment of cash, stock,
promissory notes, the withholding of shares otherwise issuable upon exercise
or a combination thereof.
 
  A restricted stock award will consist of shares of Class A Common Stock that
are nontransferable or subject to risk of forfeiture until specific conditions
are met. The restrictions will lapse in accordance with the schedule or other
conditions as the Committee determines. During the restriction period, the
recipient of restricted stock will have certain rights as a stockholder,
including the right to vote the stock and receive dividends.
 
  Changes Affecting Stock. In the event of a merger, consolidation,
reorganization, recapitalization, stock split, or stock dividend, or a
combination or reclassification of shares, the number of shares of Class A
Common Stock reserved under the Incentive Plan, the number of shares covered
by outstanding stock options and restricted stock, and the exercise prices of
outstanding options shall be adjusted proportionately.
 
  Amendment to and Termination of the Incentive Plan. The Board of Directors
may amend, modify, suspend, discontinue or terminate the Incentive Plan
without the consent of stockholders or participants; provided, however, the
Board may not (i) increase the maximum number of shares reserved for issuance
under the Plan, except with stockholder approval, or (ii) decrease the
exercise price of any option previously granted. The Incentive Plan will
terminate on a date selected by the Board of Directors in its sole discretion.
 
EMPLOYEE BENEFIT PLANS AND ARRANGEMENTS
 
  401(k) Plan. The Company has established a qualified Retirement and Savings
Plan (the "401(k) Plan") covering the Company's employees. The 401(k) Plan
incorporates the provisions of Section 401(k) of
 
                                      35
<PAGE>
 
the Internal Revenue Code. The 401(k) Plan covers all employees who have
attained the age of 21 and have completed at least one year of service.
Participants are allowed to contribute a portion of their salary with employer
matching contributions based on the contributions of the participants.
 
  Employee Stock Ownership Plan. The Company maintains a qualified Employee
Stock Ownership Plan (the "ESOP"), which is a noncontributory defined
contribution plan established for the employees of the Company. The ESOP
covers substantially all employees who have attained the age of 21 and have
completed one year of service on or before the last day of the plan year.
Vesting in the ESOP is based on years of continuous service. Vesting begins
after three years of service and is continuous through seven years of service,
at which time the participant is 100% vested. The purpose of the ESOP is to
purchase Company stock and other investments for the benefit of the employees
or their beneficiaries. Employer contributions are discretionary and are
determined annually by the Board of Directors. The Company's contribution to
the ESOP is allocated to the participants based on the ratio of their
compensation to the total compensation of all eligible participants.
Compensation is defined as total salary and wages for the plan year and will
include salary reduction contributions. The Company had no allocated shares,
shares committed-to-be released, unallocated shares or unearned shares at
October 31, 1995, 1996 and 1997. ESOP shares are treated as outstanding common
stock in the computation of earnings per share.
 
  Discretionary Bonus Plan. It is the Company's philosophy to provide a
competitive salary structure within the industry for executive officers as
well as other employees and, based on performance standards of the Company, to
provide an annual cash bonus to substantially all employees of the Company.
Generally after fiscal year-end, certain executive officers and directors
review the Company's financial performance to determine the overall bonus
compensation for employees based primarily on growth in sales and net income.
The President generally determines a level of bonus for each of the Vice
Presidents and division managers and those individuals in turn determine bonus
compensation for employees within their divisions. The Compensation Committee
will determine bonus compensation for the Company's employee directors. Bonus
compensation has been paid to employees on a company-wide basis for all but
one year of the Company's 21-year existence.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  In the past, all matters with respect to the compensation of executive
officers of the Company were determined by the members of the Board of
Directors as a whole. Betty Ketchum and Messrs. Ketchum, Paige and Windham,
who also serve as executive officers of the Company, participated as Board
members in deliberations concerning compensation. Following the completion of
the Offering, the Company will establish a Compensation Committee to determine
compensation matters with respect to the Company's employee directors.

                             CERTAIN TRANSACTIONS
 
  The Company entered into an agreement effective October 30, 1997, with
Consolidated in connection with the Company's reclassification of its Common
Stock. Consolidated is the successor in interest under an agreement between
the Company and Otter, Inc., an Oklahoma corporation, effective July 12, 1988,
as amended effective October 24, 1990, and a purchase agreement between the
Company and Vinson Supply Company, a Delaware corporation, effective March 1,
1995. Pursuant to the agreement with Consolidated, Consolidated exchanged its
holdings of Class B Common Stock for Class A Common Stock and the Company
agreed to redeem all the outstanding shares of Class C Preferred Shares held
by Consolidated for $5.0 million, plus accrued dividends, with the net
proceeds to the Company from the Offering. See "Use of Proceeds." The
agreement further provided Consolidated with certain registration rights with
respect to its holdings of Class A Common Stock. See "Description of Capital
Stock--Registration Rights."
 
  The Company leases five service and supply center locations from Sammons
Realty Corporation, an affiliate of Consolidated. These leases were assumed in
connection with Vinson Acquisition. In fiscal years 1995, 1996 and 1997,
payments to Sammons Realty Corporation aggregated $178,000, $665,000 and
$422,000, respectively. In each of October 1996 and April 1997, the Company
purchased one service and supply center from Sammons Realty Corporation for
$1,550,000 and $650,000, respectively.
 
  The Company leases its fleet of vehicles for operations, including
approximately 156 light and heavy trucks, four forklifts and 36 passenger
automobiles, from Prideco, an Oklahoma limited partnership. Prideco is owned
by BJHK Limited Partnership, an Oklahoma limited partnership ("BJHK, L.P.").
The general partner of BJHK, L.P., is the Ketchum Family Trust, of which L.
Craig Ketchum is Trustee. Individual limited partners of BJHK, L.P., include
Kent H. Ketchum, Kevin B. Ketchum and Brian C. Ketchum, each of whom is a son
of Betty J. Ketchum and a brother of L. Craig Ketchum. Additional limited
partners include the Betty Jean Haun Ketchum Living Trust and the Lewis B.
Ketchum Living Trust, of which Mrs. Ketchum serves as Trustee, and the Lewis
Craig Ketchum Living Trust, of which L. Craig Ketchum and Susan L. Ketchum
serve as trustees. The Company believes that the leases with Prideco are on
terms at least as favorable to the Company as those obtainable from unrelated
third parties in the Company's area of operations. In fiscal years 1995, 1996
and 1997, the Company made aggregate payments to Prideco for vehicle leases of
$731,800, $755,800 and $874,800.
 
  The Company leases its measurement fabrication facility in Tulsa, Oklahoma,
from Prideco pursuant to a real property lease agreement dated November 1,
1990. The primary term of the lease expired in October 1996, and the lease
arrangement will continue on a month-to-month basis until the Company
completes its new fabrication facility in the Spring of 1998, at which time
the lease will terminate. The lease payments paid to Prideco by the Company in
each of the fiscal years 1995, 1996 and 1997 aggregated $31,200.
 
  In fiscal years 1995, 1996 and 1997, compensation paid to Kent H. Ketchum
totaled $103,675, $132,870 and $160,882, respectively, compensation paid to
Kevin B. Ketchum totaled $78,166, $97,950 and $125,000, respectively, and
compensation paid to Brian C. Ketchum totalled $74,635, $93,900 and $120,800,
respectively.
 
  In fiscal years 1995, 1996 and 1997, the Company paid the law firm Noss,
Monnet & Edmiston, of which David Noss, a Director of the Company, is a
partner, $122,000, $105,000 and $157,000, respectively, for legal services and
expenses.
 
  Betty J. Ketchum owns an undivided one-half interest in real property
located in Andrews, Texas, which is leased to the Company for use in its
operations. The term of the lease expires in January, 1998, and the Company
anticipates that such lease will be renewed. The aggregate lease payments made
to Mrs. Ketchum with respect to her ownership interest was $13,800 in each of
fiscal years 1995, 1996 and 1997. The Company believes that the lease terms
are at least as favorable to the Company as those obtainable from unrelated
third parties at such location.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon consummation of the Offering, the Company will have outstanding
shares of Class A Common Stock and     shares of Class B Common Stock
(assuming the Underwriters' over-allotment option is not exercised). Each
share of Class B Common Stock is convertible into one share of Class A Common
Stock at any time at the option of the holder thereof and will automatically
convert into Class A Common Stock upon transfer to a holder that is not a
member of the Ketchum Group. The shares of Class A Common Stock sold in the
Offering will be freely tradeable without restriction or further registration
under the Securities Act, except for certain manner of sale, volume
limitations and other restrictions with respect to any shares purchased by an
affiliate of the Company. All remaining outstanding shares of Class A Common
Stock and all Class B Common Stock and shares of Class A Common Stock into
which such Class B Common Stock is convertible will be restricted securities
as that term is defined by Rule 144 promulgated under the Securities Act.
 
  In general, under Rule 144 as currently in effect, beginning 90 days after
the Offering, a person (or persons whose shares are aggregated), including
persons who may be deemed "affiliates" of the Company, who has owned
restricted securities for at least one year is entitled to sell within any
three-month period a number of shares of Class A Common Stock that does not
exceed the greater of (i) 1% of the then-outstanding shares of Common Stock
(i.e.,     shares immediately after consummation of the Offering) and (ii) the
average weekly trading volume of the Class A Common Stock on the New York
Stock Exchange during the four calendar weeks preceding the date of the sale
is filed with the Commission. Sales under Rule 144 are also subject to certain
provisions as to the manner of sale, notice requirements and the availability
of current public information about the Company. In addition, under Rule
144(k), if a period of at least two years has elapsed since the later of the
date restricted securities were acquired from the Company or the date they
were acquired from an affiliate of the Company, a stockholder who is not an
affiliate of the Company at the time of sale and who has not been an affiliate
for at least three months prior to the sale would be entitled to sell shares
of Class A Common Stock in the public market immediately without compliance
with the foregoing requirements under Rule 144. Rule 144 does not require the
same person to have held the securities for the applicable periods. The
foregoing summary of Rule 144 is not intended to be a complete description
thereof.
 
  Subject to certain exceptions, the Company and the existing stockholders of
the Company have agreed that, without the prior written consent of Morgan
Stanley & Co. Incorporated on behalf of the Underwriters, they will not,
during the period ending 180 days after the date of this Prospectus, offer for
sale, sell or otherwise dispose of any shares of Class A Common Stock or any
securities convertible into or exercisable for shares of Class A Common Stock.
See "Underwriters."
 
  The Company has granted to Consolidated registration rights with respect to
    shares of Class A Common Stock. Pursuant to such registration rights, the
holder may demand, at any time after two years from completion of the
Offering, that its holdings be registered under the Securities Act.
Additionally, if the Company effects a registration of its Class A Common
Stock, the Company is obligated to register such shares of the holder that it
may request in such registration. See "Certain Transactions."
 
  Prior to the Offering, there has been no public market for the Class A
Common Stock and no prediction can be made as to the effect, if any, that
sales of Class A Common Stock or the availability of shares for sale will have
on the market price prevailing from time to time. Following the Offering,
sales of substantial amounts of Class A Common Stock in the public market or
otherwise, or the perception that such sales could occur, could have a
material adverse effect on the prevailing market price for the Class A Common
Stock.

                         DESCRIPTION OF CAPITAL STOCK
 
  The Company is authorized to issue (i) 50,000,000 shares of Class A Common
Stock, par value $.01 per share; (ii) 50,000,000 shares of Class B Common
Stock, par value $.01 per share; and (iii) 2,000 shares of preferred stock,
par value $2,500 per share. As of the date of this Prospectus, the Company had
issued and outstanding     shares of Class A Common Stock,     shares of Class
B Common Stock and 2,000 shares of Class C Preferred Stock. The following
summary does not purport to be complete, and reference is made to the more
detailed provisions of the Restated Certificate of Incorporation and Bylaws,
each of which is filed as an exhibit to the Registration Statement of which
this Prospectus is a part.
 
CLASS A AND CLASS B COMMON STOCK
 
  Voting Rights. Each share of Class A Common Stock is entitled to one vote
and each share of Class B Common Stock is entitled to ten votes on all matters
submitted to a vote of the stockholders. Subject to applicable limitations of
law, the Class A Common Stock and the Class B Common Stock vote together as a
single class on all matters presented for a vote of the stockholders. The
holders of a majority of all outstanding shares of Class A Common Stock or
Class B Common Stock, voting as separate classes, must also approve amendments
to the Restated Certificate of Incorporation that adversely affect the shares
of their class. Shares of Class A Common Stock and Class B Common Stock do not
have cumulative voting rights.
 
  Dividends. Each share of Class A Common Stock and Class B Common Stock is
entitled to dividends at the same rate if, as and when declared by the Board
of Directors from any assets legally available therefor, subject to any
preference in favor of any outstanding preferred stock. Any dividends so
declared and payable in cash, capital stock of the Company (other than Class A
Common Stock or Class B Common Stock) or other property will be paid pro rata
on the shares of Class A Common Stock and Class B Common Stock. If a dividend
or distribution is to be paid in shares of Common Stock, it must be declared
and paid proportionately to the holders of both classes of Common Stock either
(i) in Class A Common Stock to holders of both Class A and Class B Common
Stock or (ii) in Class A Common Stock to holders of Class A Common Stock and
in Class B Common Stock to holders of Class B Common Stock.
 
  Convertibility. Class A Common Stock has no conversion rights. Each share of
Class B Common Stock is convertible at any time, at the option of and without
cost to the stockholder, into one share of Class A Common Stock upon surrender
of the certificate or certificates evidencing the Class B Common Stock to be
converted. Shares of Class B Common Stock will automatically convert to equal
shares of Class A Common Stock if such shares are sold, transferred or
otherwise disposed of to any third party other than a member of the Ketchum
Group. Once shares of Class B Common Stock are converted into shares of Class
A Common Stock, such shares may not be converted back into Class B Common
Stock.
 
  Merger or Consolidation. The Company's Restated Certificate of Incorporation
further provides that upon any merger, consolidation, reorganization or other
business combination with any other entity, the consideration to be received
per share by the holders of Class A Common Stock and Class B Common Stock
shall be identical, except the voting rights of any securities received by
holders of Class A Common Stock may differ from the voting rights of any
securities received by holders of Class B Common Stock to the extent that the
voting rights differ between shares of Class A Common Stock and shares of
Class B Common Stock.
 
  Liquidation Rights. In the event of the dissolution of the Company, whether
voluntary or involuntary, after payment of all liabilities and distribution to
the holders of Preferred Stock, if any, of amounts to which they may be
preferentially entitled, the holders of Class A Common Stock and Class B
Common Stock are entitled to share ratably in the assets of the Company
legally available for distribution to its stockholders.
 
                                      40
<PAGE>
 
  Other Rights. The holders of Common Stock are not entitled to preemptive or
subscription rights, and there are no redemption or sinking fund provisions
applicable to the Common Stock. The Common Stock currently outstanding is, and
the Class A Common Stock to be issued in the Offering will be, validly issued,
fully paid and non-assessable.
 
PREFERRED STOCK
 
  The Board of Directors of the Company is empowered, without approval of the
stockholders, to cause shares of preferred stock to be issued in one or more
series, with the numbers of shares of each series to be determined by it. The
Board of Directors is authorized to fix and determine the powers,
designations, preferences and relative, participating, optional or other
rights (including, without limitation, voting powers, full or limited,
preferential rights to receive dividends or assets upon liquidation, rights of
conversion or exchange into Common Stock, preferred stock of any series or
other securities, redemption provisions and sinking fund provisions) between
series and between the preferred stock or any series thereof and the Common
Stock, and the qualifications, limitations or restrictions of such rights.
 
  The Company has issued a series of preferred stock designated Class C
Preferred Stock. All of the 2,000 shares of Series C Preferred Stock currently
outstanding will be redeemed by the Company from the net proceeds to the
Company of the Offering. See "Use of Proceeds." The Company has no present
intention to issue additional shares of preferred stock. The issuance of
shares of preferred stock, or the issuance of rights to purchase such shares,
could be used to discourage an unsolicited acquisition proposal. For instance,
the issuance of a series of preferred stock might impede a business
combination by including class voting rights that would enable the holders to
block such a transaction, or such issuance might facilitate a business
combination by including voting rights that would provide a required
percentage vote of the stockholders. In addition, under certain circumstances,
the issuance of preferred stock could adversely affect the voting power of the
holders of the Common Stock. Although the Board of Directors is required to
make any determination to issue such stock based on its judgment as to the
best interests of the stockholders of the Company, the Board of Directors
could act in a manner that would discourage an acquisition attempt or other
transaction that some or even a majority of the stockholders might believe to
be in their best interests or in which stockholders might receive a premium
for their stock over the then market price of such stock. The Board of
Directors does not at present intend to seek stockholder approval prior to any
issuance of currently authorized stock, unless otherwise required by law or
the rules of any market on which the Company's securities are traded.
 
RESTRICTIONS ON TRANSFER OF CLASS B COMMON STOCK
 
  The     shares of Class B Common Stock held by BJHK Limited Partnership (the
"Partnership"), an Oklahoma limited partnership controlled by the Ketchum
Group, are restricted under the limited partnership agreement of the
Partnership from being sold by the Partnership except in connection with the
sale of all Class B Common Stock, including the Class B Common Stock held by
K.F. Enterprises, L.L.C. This restriction may be amended by the affirmative
vote of holders of 80% of the total Partnership units upon the Company
becoming a "public" company under the Exchange Act. The     shares of Class B
Common Stock held of record by K. F. Enterprises, L.L.C., an Oklahoma limited
liability company ("Enterprises"), are also subject to substantially similar
restrictions prohibiting sale unless in connection with the sale of all the
shares of the Class B Common Stock. The operating agreement of Enterprises
provides that this restriction may be amended upon the affirmative vote of a
majority in ownership interests of Enterprises upon the Company becoming a
"public" company under the Exchange Act. Each of the limited partnership
agreement of the Partnership and operating agreement of Enterprises prohibit a
distribution of the shares of Class B Common Stock in kind to any person or
entity prior to the twentieth anniversary of the death of Betty J. Ketchum.

OKLAHOMA TAKEOVER STATUTES
 
  The Oklahoma General Corporation Act contains certain provisions (the
"Business Combination Provisions") that may have the effect of preventing,
discouraging or delaying a change in control of the Company. The Business
Combination Provisions prohibit certain business combinations between a
corporation and any person who has acquired 15% or more of the voting stock of
the corporation (an "interested stockholder") for a period of three years from
the date such stockholder became an interested stockholder, unless such
interested stockholder (a) prior to becoming an interested stockholder,
obtained the approval of the Board of Directors of either the business
combination or the transaction that resulted in such person becoming an
interested stockholder, (b) acquired at least 85% of the outstanding shares of
voting stock of the corporation (excluding shares owed by persons who are
directors or officers and by certain employee stock plans) in the same
transaction in which the interested stockholder became an interested
stockholder, or (c) if on or subsequent to the date the interested stockholder
became an interested stockholder, the business combination is approved by the
Board of Directors and is authorized at a meeting of stockholders by the
affirmative vote of at least two-thirds of the voting stock that is not owned
by the interested stockholder. The Business Combination Provisions define a
"business combination" to include (a) any merger of consolidation involving
the corporation and an interested stockholder, (b) any sale, transfer, pledge
or other disposition involving an interested stockholder of 10% or more of the
assets or outstanding stock of the corporation, (c) subject to certain
exceptions, any transaction which results in the issuance or transfer by the
corporation of any stock of the corporation to an interested stockholder, (d)
any transaction involving the corporation which has the effect of increasing
the proportionate share of the stock of any class or series of the corporation
beneficially owned by the interested stockholder, (e) the receipt by an
interested stockholder of any loans, guarantees, pledges or other financial
benefits provided by or through the corporation, or (f) any share acquisition
by the interested stockholder pursuant to certain provisions of the Oklahoma
General Corporation Act.
 
  In general, an Oklahoma corporation must specifically elect, through an
amendment to its bylaws or certificate, not to be governed by the Business
Combination Provisions. The Company has not made such election and, therefore,
is subject to the terms of the statute.
 
  The Oklahoma Control Shares Act provides that, except in limited
circumstances such as mergers, any person or group of persons that acquires
the power to vote one-fifth or more of certain corporations' shares shall not
have the right to vote such shares unless such person or group is granted
voting rights by the holders of a majority of the votes entitled to be cast
excluding "interested shares." If the approval of voting power for the shares
is obtained, additional stockholder approvals are required when a stockholder
acquires the power to vote one-third or more and a majority or more of the
voting power of the corporation's shares. In the absence of such approval, the
additional shares acquired by the stockholder may not be voted until the
expiration of three years after the date of a vote of stockholders failing to
approve the voting power of such shares.
 
  The Oklahoma Take-Over Disclosure Act (the "Disclosure Act") prohibits any
person from making a takeover offer to purchase the equity securities of a
target company as defined in the Disclosure Act, or to acquire any such
securities pursuant to such offer, unless such offer is properly filed with
and approved by the Administrator of the Oklahoma Department of Securities.
The definition of a "take-over offer" under the Disclosure Act is the offer to
acquire any equity securities of a target company where, pursuant to the
offer, either: (a) the offeror would be directly or indirectly beneficial
owner of more than ten percent of any class of the outstanding equity
securities of the target company, or (b) the beneficial ownership of the
offeror of any class of the outstanding equity securities of the target
company would be increased by more than five percent.
 
  The term "target company" is defined in the Disclosure Act as an "issuer of
publicly traded equity securities of which at least twenty percent of its
equity securities are beneficially held by residents of Oklahoma and which
have substantial assets in Oklahoma."
 
  The tender offer must be filed with the Administrator with a registration
statement setting forth detailed information regarding (a) the identity of the
offeror and all other persons on whose behalf the acquisition is being
 
                                      42
<PAGE>
 
affected; (b) the source or amount of funds to be used in the acquisition; (c)
if the purpose of the offer is to acquire control of the target company, all
plans to make material changes within the target, such as liquidation, changes
in management or changes in employment policies; (d) the number of equity
securities owned beneficially by the offeror; (e) the material terms of any
contractual arrangements whereby the persons filing the statement will
transfer or acquire additional securities to or from another; and (f) detailed
information regarding the offeror, including business activities for the past
three years.
 
  In addition to this registration statement filed with the Administrator, the
offeror must deliver a copy of the registration statement to the target
company and publicly disclose the material terms of the proposed offer no
later than the date of filing. The Disclosure Act also contains penalties for
its violation.
 
  The cumulative effect of the Business Combination Provisions, the Control
Share Act and the Disclosure Act may be to discourage or hinder a hostile
acquisition of the Company.
 
CERTAIN PROVISIONS OF THE RESTATED CERTIFICATE OF INCORPORATION AND BYLAWS
 
  Oklahoma law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of directors' fiduciary duty of care. The duty of care
requires that, when acting on behalf of the corporation, directors must
exercise an informed business judgment based on all material information
reasonably available to them. Absent the limitations authorized by Oklahoma
law, directors are accountable to corporations and their stockholders for
monetary damages for conduct constituting gross negligence in the exercise of
their duty of care. Oklahoma law enables corporations to limit available
relief to equitable remedies such as injunction or rescission. The Restated
Certificate of Incorporation limits the liability of directors of the Company
to the Company or its stockholders to the fullest extent permitted by the
Oklahoma General Corporation Act. Specifically, directors of the Company will
not be personally liable for monetary damages for breach of a director's
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Company or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for unlawful payments of dividends or unlawful
stock repurchases or redemptions or (iv) for any transaction from which the
director derived an improper personal benefit. The inclusion of this provision
in the Restated Certificate of Incorporation may have the effect of reducing
the likelihood of derivative litigation against directors, and may discourage
or deter stockholders or management from bringing a lawsuit against directors
for breach of their duty of care, even though such an action, if successful,
might otherwise have benefited the Company and its stockholders. The Company's
Bylaws provide indemnification to the Company's officers and directors and
certain other persons with respect to certain matters.
 
  The Company's Bylaws contain provisions requiring that advance notice be
delivered to the Company of any business to be brought by a stockholder before
an annual meeting of stockholders, and providing for certain procedures to be
followed by stockholders in nominating persons for election to the Board of
Directors of the Company. Generally, such advance notice provisions provide
that written notice must be given to the Secretary of the Company by a
stockholder (i) in the event of business to be brought by a stockholder before
an annual meeting, not less than 90 days prior to the anniversary date of the
immediately preceding annual meeting of stockholders of the Company (with
certain exceptions if the date of the annual meeting is different by more than
specified amounts from the anniversary date) and (ii) in the event of
nominations of persons for election to the Board of Directors by any
stockholder, (a) with respect to an election to be held at the annual meeting
of stockholders, not less than 90 days prior to the anniversary date of the
immediately preceding annual meeting of stockholders of the Company (with
certain exceptions if the date of the annual meeting is different by more than
specified amounts from the anniversary date) and (b) with respect to an
election to be held at a special meeting of stockholders for the election of
directors, not later than the close of business on the tenth day following the
day on which notice of the date of the special meeting was mailed to
stockholders or public disclosure of the date of the special meeting was made,
whichever first occurs. Such notice must set forth specific information
regarding such stockholder and such business or director nominee, as described
in the Company's Bylaws.

REGISTRATION RIGHTS
 
  The Company has entered into an agreement granting registration rights to
Consolidated with respect to       shares of Class A Common Stock. Under the
agreement, Consolidated may demand, at any one time after two years following
the consummation of the Offering, that such holdings of Class A Common Stock
be registered under the Securities Act, and may request at any time when the
Company registers additional shares of Class A Common Stock that such holdings
of Class A Common Stock be included in such registration.

  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Class A Common
Stock offered hereby are subject to the approval of certain legal matters by
their counsel and to certain other conditions. The Underwriters are obligated
to take and pay for all of the shares of Class A Common Stock offered hereby

  The Underwriters initially propose to offer part of the shares of Class A
Common Stock directly to the public at the public offering price set forth on

concession not in excess of $   a share under the public offering price. Any
Underwriter may allow, and such dealers may reallow, a concession not in
excess of $   a share to other Underwriters or to certain other dealers. After
the initial offering of the shares of Class A Common Stock, the offering price
and other selling terms may from time to time be varied by the Representative.
 
  The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of
additional shares of Class A Common Stock at the public offering price set
forth on the cover page hereof, less underwriting discounts and commissions.
The Underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, made in connection with the offering of the shares of
Class A Common Stock offered hereby. To the extent such option is exercised,
each Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional shares of Class
A Common Stock as the number set forth next to such Underwriter's name in the
preceding table bears to the total number of shares of Class A Common Stock
set forth next to the names of all Underwriters in the preceding table.
 
  The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Class A Common Stock offered by them.
 
  At the request of the Company, the Underwriters have reserved up to
shares of Class A Common Stock for sale at the initial public offering price
to the Company's employees, officers and directors and to other individuals
having relationships with the Company. The number of shares available for sale
to the general public will be reduced to the extent such individuals purchase
such reserved shares. Any reserved shares which are not so purchased will be
offered by the Underwriters to the general public on the same basis as the
other shares offered hereby. Reserved shares purchased by such individuals
will, except as restricted by applicable securities laws, be available for
resale following the Offering.

  The Company will apply to have the Class A Common Stock listed on the New
York Stock Exchange under the symbol "RMN."
 
  Each of the Company and the directors, executive officers and other
stockholders of the Company has agreed that, without the prior written consent
of the Representative on behalf of the Underwriters, it will not, during the
period ending 180 days after the date of this Prospectus, (i) offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase or
otherwise transfer, lend or dispose of, directly or indirectly, any shares of
Class A Common Stock or any securities convertible into or exercisable or
exchangeable for Class A Common Stock or (ii) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Class A Common Stock, whether any
such transaction described in clause (i) or (ii) above is to be settled by
delivery of Class A Common Stock or such other securities, in cash or
otherwise. The restrictions in this paragraph do not apply to transactions by
any person other than the Company relating to shares of Class A Common Stock
or other securities acquired in open market transactions after the completion
of the Offering.
 
  In order to facilitate the offering of the Class A Common Stock, the
Underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of the Class A Common Stock. Specifically, the Underwriters
may over-allot in connection with the Offering, creating a short position in
the Class A Common Stock for their own account. In addition, to cover over-
allotments or to stabilize the price of the Class A Common Stock, the
Underwriters may bid for, and purchase, shares of Class A Common Stock in the
open market. Finally, the underwriting syndicate may reclaim selling
concessions allowed to an Underwriter or a dealer for distributing the Class A
Common Stock in the Offering, if the syndicate repurchases previously
distributed Class A Common Stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the Class A Common Stock above
independent market levels. The Underwriters are not required to engage in
these activities, and may end any of these activities at any time.
 
  The Company, the Selling Stockholder and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
PRICING OF THE OFFERING
 
  Prior to the Offering, there has been no public market for the Class A
Common Stock. The initial public offering price will be determined by
negotiations between the Company and the Representative. Among the factors to
be considered in determining the initial public offering price will be the
future prospects of the Company and its industry in general, sales, earnings
and certain other financial operating information of the Company in recent
periods, and the price-earnings ratios, price-sales ratios, market prices of
securities and certain financial and operating information of companies
engaged in activities similar to those of the Company. The estimated initial
public offering price range set forth on the cover page of this Prospectus is
subject to change as a result of market conditions and other factors.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
Red Man Pipe & Supply Co.
 
  We have audited the accompanying consolidated balance sheets of Red Man Pipe
& Supply Co. and Subsidiaries as of October 31, 1996 and 1997, and the related
consolidated statements of operations, preferred stock and stockholders'
equity, and cash flows for each of the three years in the period ended October
31, 1997. 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 misstatements. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the consolidated 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 consolidated financial position
of Red Man Pipe & Supply Co. and Subsidiaries as of October 31, 1996 and 1997,
and the consolidated results of their operations and their cash flows for each
of the three years in the period ended October 31, 1997, in conformity with
generally accepted accounting principles.
 
  As discussed in Note 2, during 1997 the Company changed its method of
accounting for inventories from the Last-In, First-Out method to the First-In,
First-Out method. Accordingly, previously reported amounts have been restated
to reflect this change in accounting.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF OPERATIONS
 
  Nature of Operations--Red Man Pipe & Supply Co. (the "Company") is a
distributor of tubular goods, including oil country tubular goods and line
pipe, and the operation of service and supply centers which distribute
maintenance, repair and operating products utilized in the energy industry as
well as industrial products consisting primarily of line pipe, valves,
fittings and flanges. The Company distributes products and tubular goods
through 42 service and supply centers and 11 sales locations strategically
located close to the major hydrocarbon producing and refining areas of the
United States.
 
  Principles of Consolidation--The consolidated financial statements include
the accounts of Red Man Pipe & Supply Co. and its wholly-owned subsidiaries,
Red Man Ventures, Inc. and Red Man International, Inc. All significant
intercompany profits, transactions and balances have been eliminated. During
1995, 1996 and 1997, there were no significant assets or operations in these
subsidiaries.
 
  Inventories--The Company values its inventories, all of which are finished
goods, at the lower of cost or market. In fiscal 1997 the Company changed its
method of determining cost for inventories from the Last-In, First-Out
("LIFO") method to the First-In, First-Out ("FIFO") method (See Note 2). The
change was made to improve interim financial reporting and to achieve a better
presentation and comparability of period to period operating and financial
results.
 
  Property, Plant and Equipment--Property, plant and equipment are recorded at
cost and include expenditures for facilities as well as significant
improvements to existing facilities. When assets are retired or otherwise
disposed of, the cost and related accumulated depreciation are removed from
the accounts and any gain or loss is reflected in income for the period.
Maintenance and repairs are charged to expense as incurred.
 
  Depreciation and amortization are computed utilizing both straight-line and
accelerated methods over the estimated useful lives of the property. The
ranges of estimated useful lives for financial reporting are as follows:

                                                                           -----

</TABLE>
 
  Revenue Recognition--The Company recognizes revenue as products are shipped
or accepted by the customer.
 
  Income Taxes--The Company follows the provisions of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No. 109").
SFAS No. 109 requires the measurement of deferred tax assets and liabilities
based on the future tax consequences attributable to the differences between
the financial statement carrying amounts of existing assets and liabilities
and their respective tax bases.
 
  Treasury Stock--The Company utilizes the cost method for accounting for its
treasury stock acquisitions and dispositions.
 
  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 and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Earnings Per Share--Earnings per share amounts are based on the weighted
average number of shares of common stock outstanding during the respective
periods. Net income is adjusted for dividends on preferred stock.
 
  Reclassifications--Certain reclassifications have been made to the balances
reported for fiscal years 1995 and 1996 to conform to fiscal year 1997
reporting.
 
  Impact of New Financial Accounting Pronouncement--In February 1997, the
Financial Accounting Standards Board issued Statement of Financial Accounting
Standards No. 128, Earnings Per Share ("SFAS No. 128"). SFAS No. 128 will
change the computation, presentation and disclosure requirements for earnings
per share. Such pronouncement requires the presentation of "basic" and
"diluted" earnings per share. This statement is effective for financial
statements issued for periods ending after December 15, 1997, including
interim periods, and requires restatement of all prior period earnings per
share amounts. The Company will adopt SFAS No. 128 in the second quarter of
fiscal 1998; however, this pronouncement is not expected to have a material
effect on its earnings per share when adopted.
 
2. CHANGE IN ACCOUNTING FOR INVENTORIES
 
  At the beginning of fiscal 1997, the Company changed its method of valuation
for inventories from the LIFO method to the FIFO method. The financial
statements for fiscal 1995 and 1996 have been restated to reflect the change.
Accordingly, the value of inventories was increased by $164,000 for fiscal
1995 and was decreased by $420,000 for fiscal 1996. The effect of the change
in accounting for inventories was to decrease net income by $7,000 ($.04 per
share) and $362,000 ($1.89 per share) for fiscal 1995 and 1996, respectively.

(A) During fiscal 1997 the Credit Facility was amended permitting the Company
    to borrow amounts up to the lesser of (i) $100.0 million or (ii) an amount
    equal to the borrowing base plus the outstanding balance on the term loan
    portion. On the revolving credit portion of the Credit Facility, the
    Company is permitted to borrow amounts up to the lesser of (i) $100.0
    million less the outstanding principal balance of the term loan portion or
    (ii) an amount equal to the borrowing base amount. The borrowing base
    amount is determined through a computation of eligible accounts receivable
    and inventories as defined in the revolving credit facility. The amount of
    unused borrowings available under this facility at October 31, 1997 is
    $18,554,000. The borrowings under the revolving credit facility bear an
    interest rate equal to the lesser of the bank's prime rate plus .25%
    (8.75% at October 31, 1997) or LIBOR plus a margin based upon a trailing
    12-month calculation of EBITDA, as defined in the Credit Facility (7.25%
    at October 31, 1997). The $10,000,000 term loan portion of the revolving
    Credit Facility bears interest at the lesser of the bank's prime rate plus
    .5% (9.0% at October 31, 1997) or LIBOR plus a margin based upon a
    trailing 12-month calculation of EBITDA, as defined in the Credit Facility
    (7.50% at October 31, 1997). The Company pays a fee on the unused portion
    of the Credit Facility equal to .375% per year.
 
    During fiscal 1997, the term of the Credit Facility was extended to
  October 31, 2000. At the conclusion of the term, such facility shall be
  automatically extended by one year unless the Company or the lender does
  not desire to extend the agreement and as long as no default has occurred.
 
    The Company is advanced amounts under the revolving credit facility to
  meet vendor and other obligations and all collections of revenues are used
  to reduce the amount outstanding. The projected borrowing base during 1998
  is expected to be in excess of amounts required and, accordingly, the
  revolving credit facility is classified as long-term.
 
    The Company is subject to a number of covenants under the Credit
  Facility. The most restrictive covenants include maintenance of leverage
  ratios and current ratios, minimum pre-tax earnings from operations and a
  limit on new debt obligations. The Credit Facility is collateralized by
  substantially all assets of the Company including accounts receivable,
  inventories and equipment.
 
    Based upon the borrowing rates currently available to the Company for
  bank borrowings with similar terms, the Company believes that the carrying
  amount of these borrowings at October 31, 1997, approximates fair value.

5. STOCKHOLDERS' EQUITY
 
  The Company has two classes of common stock. One class consists of 500,000
authorized shares of $1 par value voting Class A Common Stock, and the other
class consists of 500,000 authorized shares of $1 par value non-voting Class B
Common Stock. (See Note 12).
 
  The Company also has 2,000 authorized and outstanding shares of $2,500 par
value Class C Preferred Stock. The Class C Preferred Stock bears an annual
cumulative dividend of 5%, payable quarterly. Dividends paid on Class C
preferred stock during 1995 totaled $125,000 and during both 1996 and 1997
totaled $250,000. The Class C Preferred Stock is non-voting and subordinate to
indebtedness of the Company, but bears full preference to the Common Stock as
to dividends and to redemption in the event of liquidation of the Company. The
Class C Preferred Stock is redeemable on March 31, 2000 at par value with no
option for early redemption. The stock was offered as part of the purchase
price in the Company's asset acquisition (See Notes 9 and 12).
 
6. LEASES
 
  The Company occupies facilities and operates motor vehicles under long-term
operating leases that expire during 1998 through 2004. Certain of these leases
are subject to renewal or purchase options and escalation clauses. The
following is a schedule by year of future minimum lease payments required
under the operating leases that have initial or remaining noncancellable lease
terms in excess of one year as of October 31, 1997:

8. EMPLOYEE BENEFIT PLANS
 
  The Company maintains a qualified Employee Stock Ownership Plan ("ESOP"),
which is a noncontributory defined contribution plan established for the
employees of the Company. The ESOP covers substantially all employees who have
attained the age of twenty-one (21) and have completed one year of service on
or before the last day of the plan year. Vesting in the ESOP is based on years
of continuous service. Vesting begins after three years of service and is
continuous through seven years of service, at which time the participant is
100% vested. The purpose of the ESOP is to purchase Company stock and other
investments for the benefit of the employees or their beneficiaries. Employer
contributions are discretionary and are determined annually by the Company's
Board of Directors. The employer's cash and accrued contributions to this plan
were approximately $84,000 in each of fiscal years 1995, 1996 and 1997. The
Company's contribution to the ESOP is allocated to the participants based on
the ratio of their compensation to the total compensation of all eligible
 
                                     F-11

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
participants. Compensation is defined as total salary and wages for the plan
year and will include salary reduction contributions. The Company had no
allocated shares, shares committed-to-be released, unallocated shares or
unearned shares at October 31, 1995, 1996 and 1997. ESOP shares are treated as
outstanding common stock in the computation of earnings per share.
 
  The Red Man Pipe & Supply Co. Retirement Savings Plan (the "Plan")
incorporates the provisions of Section 401(k) of the Internal Revenue Code.
The Plan covers all employees who have attained the age of twenty-one (21) and
have completed at least one year of service. Participants are allowed to
contribute a portion of their salary with employer matching contributions
based on the contributions of the participants. The employer matching
contributions were approximately $180,000, $222,000 and $254,000 for the years
ended October 31, 1995, 1996 and 1997, respectively.
 
  The Company also has an employee Medical Reimbursement Plan ("MRP") which
entitles eligible employees to be reimbursed for certain medical and dental
expenses incurred by them or their family up to $500 per employee, per year.
All full-time employees are eligible to participate in the MRP after having
completed six months of employment with the Company. The Company's Board of
Directors determines annually whether or not the MRP will be funded for the
current year. The Company's contributions to the MRP were approximately
$165,000, $190,000 and $202,000 for the years ended October 31, 1995, 1996 and
1997, respectively.
 
9. ASSET PURCHASE
 
  On April 3, 1995, the Company purchased substantially all of the inventory
and fixed assets of the supply division of Vinson Supply Company for a
purchase price of $19,526,000. Under the terms of the Purchase Agreement, the
Company gave cash, a short-term note, and 2,000 shares of Class C Preferred
Stock as consideration for the assets purchased.
 
10. RELATED PARTY TRANSACTIONS
 
  The Company leases certain equipment from Prideco, a partnership related by
common ownership and control. The Company also leases certain buildings from
Prideco. Amounts paid to Prideco for building and equipment rental were
$763,000, $787,000 and $906,000 for 1995, 1996 and 1997, respectively.
 
  In 1995, 1996 and 1997, the Company paid rent of approximately $178,000,
$665,000 and $422,000, respectively, to an affiliate of its Class C preferred
stockholder. In each of October 1996 and April 1997, the Company purchased one
service and supply store from an affiliate for $1,550,000 and $650,000,
respectively.
 
  In fiscal years 1995, 1996 and 1997, the Company paid a law firm, of which a
director of the Company is a partner, legal fees and expenses totaling
$122,000, $105,000 and $157,000, respectively.
 
  A stockholder leases a service and supply center to the Company for use in
its operations. The stated term of the lease will expire in January 1998. The
aggregate lease payments made to the stockholder totaled $13,800 in each of
fiscal years 1995, 1996 and 1997.
 
11. CONCENTRATION AND CREDIT RISK
 
  Most of the Company's business activity is with customers in the energy
industry. In the normal course of business, the Company grants credit to these
customers. Trade accounts receivable are primarily from these customers. The
Company generally does not require collateral on its trade receivables. During
1995, 1996 and 1997, the Company had sales to one customer amounting to
approximately 14%, 11% and 12% of sales, respectively.
 
                                     F-12
<PAGE>
 
                  RED MAN PIPE & SUPPLY CO. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  While the Company's normal business practice is to maintain minimal cash
balances on hand in its bank accounts, at October 31, 1997, the Company had
cash at one financial institution in excess of federal deposit insurance
limits. The account is swept each day and applied against the Company's
revolving credit facility; therefore, management believes that any risk
associated with cash deposits is negligible.
 
  A substantial portion of the Company's tubular goods sales is purchased from
two manufacturers. The Company has no long-term supply contracts with these
manufacturers which would assure the Company of a continued supply of tubular
good products in the future. Although the Company believes there are numerous
manufacturers having the capacity to supply its tubular goods products, the
loss of one of these major suppliers could have a material adverse effect on
the Company's business, financial condition or results of operations as such
loss would require the Company to rely more heavily on its other existing
suppliers or develop relationships with new suppliers, which may cause the
Company to pay higher prices for products due to a loss of the volume discount
benefits currently obtained from its two major suppliers.
 
12. SUBSEQUENT EVENTS
 
 Initial Public Offering
 
  In December 1997 the Company filed a registration statement with the
Securities and Exchange Commission to register the sale of shares of its Class
A common stock (the "Offering").
 
  In connection with the Offering, the Company's Certificate of Incorporation
was amended and restated in December 1997 to increase and reclassify the
Company's authorized Common Stock from 500,000 shares of Class A Common Stock,
par value $1.00 per share, having one vote per share and 500,000 shares of
non-voting Class B Common Stock, par value $1.00 per share, to 50,000,000
shares of Class A Common Stock, par value $.01 per share, having one vote per
share and 50,000,000 shares of Class B Common Stock, par value $.01 per share,
having ten votes per share, respectively. Simultaneously therewith, certain
stockholders effected an exchange of Common Stock. Additionally, in connection
with the Offering, the Company intends to effect a stock split of its Class A
Common Stock and Class B Common Stock. All shares and per share information
included within the audited financial statements and related footnotes reflect
historical amounts and have not been restated to reflect the increased and
reclassified common stock and stock split. Upon completion of the initial
public offering, the Company will reflect the increased and reclassified
common stock and stock split in the historical financial statements.
 
 
 Incentive Stock Plan
 
  In December 1997, the Company established the Red Man Pipe & Supply Co.
Incentive Stock Plan (the "Incentive Plan") in which officers, employees and
directors are eligible to participate. The Incentive Plan authorizes the grant
of incentive stock options, non-qualified stock options and awards of
restricted stock. Incentive stock options may only be awarded to employees and
the exercise price may not be less than the fair market value of the Class A
common stock on the date of grant (or 110% of such fair market value if
granted to employees who own more than 10% of the combined voting power of all
classes of the stock of the Company). The exercise price of non-qualified
stock options shall be determined by the Board of Directors or its committee
and shall not be less than the fair market value of the Class A Common Stock
on the date of grant. The vesting period for all options will be determined by
the Board of Directors or its committees at the time of the grant. The
incentive stock option may not be exercised after the expiration of 10 years
from the date of grant (or 5 years if granted to employees who own more than
10% of the combined voting power of all classes of stock of the Company). No
options have been granted under the Incentive Plan.

  A restricted stock award will consist of shares of Class A Common Stock that
are nontransferable or subject to risk of forfeiture until specific conditions
are met. The restrictions will lapse in accordance with the schedule or other
conditions as determined by the Board of Directors or its committee. During
the restriction period, the recipient of restricted stock will have certain
rights as a stockholder, including the right to vote the stock and receive
dividends. No awards have been granted under the Incentive Plan.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Company's Bylaws provide that the registrant shall indemnify its
officers and directors as permitted by the Oklahoma General Corporation Act.
Pursuant to Section 31 of the Oklahoma General Corporation Act, the registrant
generally has the power to indemnify its present and former directors and
officers against expenses and liabilities incurred by them in connection with
any suit to which they are, or are threatened to be made, a party by reason of
their serving in those positions so long as they acted in good faith and in a
manner they reasonably believed to be in, or not opposed to, the best
interests of the registrant, and with respect to any criminal action, they had
no reasonable cause to believe their conduct was unlawful. With respect to
suits by or in the right of the registrant, however, indemnification is
generally limited to attorneys' fees and other expenses and is not available
if the person is adjudged to be liable to the registrant unless the court
determines that indemnification is appropriate. The statute expressly provides
that the power to indemnify authorized thereby is not exclusive of any rights
granted under any bylaw, agreement, vote of stockholders or disinterested
directors, or otherwise. The Company also has the power to purchase and
maintain insurance for its directors and officers. The Company's Restated
Certificate of Incorporation also eliminates, subject to certain limitations,
the liability of the Company's directors for monetary damages for breach of
their fiduciary duty as directors.
 
  The preceding discussion of the registrant's bylaws and Section 31 of the
Oklahoma General Corporation Act is not intended to be exhaustive and is
qualified in its entirety by the Company's Bylaws and Section 31 of the

ITEM 17. UNDERTAKINGS.
 
  1. The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closings specified in the Underwriting Agreement
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
  2. Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  3. The undersigned Registrant hereby undertakes that:
 
    (i) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 430A and contained in the form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (ii) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
Red Man Pipe & Supply Co.
 
  In connection with our audits of the consolidated financial statements of
Red Man Pipe & Supply Co. and Subsidiaries as of October 31, 1996 and 1997,
and for each of the three years in the period ended October 31, 1997, which
financial statements are included in the Prospectus, we have also audited the
financial statement schedule listed in Item 16 herein.
 
  In our opinion, the financial statement schedule, when considered in
relation to the basic financial statements taken as a whole, presents fairly,
in all material respects, the information required to be included therein.

          (6)  The rights of the shares of that series in the event of voluntary

          (8)  Any other relative rights, preferences and limitations of that
               series.

     (b)  Dividends on outstanding shares of Preferred Stock shall be declared

     (c)  No holder of shares of Preferred Stock shall be entitled to any
          preemptive rights with respect to subscribing for or purchasing any
          part of any new or additional issue or sale or reservation of stock or
          securities of any class or kind whatsoever.

2.   Class A and Class B Common Stock.
     -------------------------------- 

     (a)  Neither the outstanding shares of Class A Common Stock nor the
          outstanding shares of Class B Common Stock may be subdivided,
          consolidated, reclassified or otherwise changed unless
          contemporaneously therewith the outstanding shares of the other class
          of common stock are subdivided, consolidated, reclassified or
          otherwise changed in the same proportion and in the same manner.

     (b)  The holders of Class A Common Stock and Class B Common Stock shall
          have the exclusive right to vote for the election of Directors (other
          than in the case of newly created directorships and vacancies, which
          may be filled by the remaining Directors) and on all other matters
          requiring Stockholder action, with each share of Class A Common Stock
          entitling the holder thereof to one (1) vote on any matter submitted
          to the Stockholders for a vote, and each share of Class B Common Stock
          entitling the holder thereof to ten (10) votes on any matter submitted
          to the Stockholders for a vote, provided that such holder of the Class
          B Common Stock is a member of the Ketchum Group (as hereinafter
          defined); and every reference in this Restated Certificate of
          Incorporation or the By-Laws of the Corporation, as in effect from
          time to time, to a majority or other portion of stock shall refer to
          such majority or other proportion of the votes of such stock;
          provided, however, that, except as required by law, holders of Class A
          Common Stock and Class B Common Stock shall, on every matter submitted
          to the Stockholders for a vote, vote as a single class, and in no
          case, except as required by law, shall the holders of Class A Common
          Stock or Class B Common Stock be entitled to vote separately as a
          class, and provided that the number of authorized shares of any class
          or classes of stock may be increased or decreased (but not below the
          number of shares thereof then outstanding) by the affirmative vote of
          a majority of the votes of the voting stock of the Corporation; and as
          used in this Restated Certificate of Incorporation, the "Ketchum
          Group" shall mean Betty J. Ketchum, and the lineal descendants of
          Lewis B. Ketchum and Betty J. Ketchum (collectively, the "Ketchum
          Family"), and trusts, partnerships or other entities controlled by or
          for the benefit of any member or members of the Ketchum Family.

     (c)  Upon any merger, consolidation, reorganization or other business
          combination of the Corporation and any other entity, the consideration
          to be received per share by the holders of the Class A Common Stock
          and Class B Common Stock as a result of such merger, consolidation,
          reorganization or other business combination shall be identical,
          except that the voting rights of any securities received by holders of
          Class A Common Stock may differ from the voting rights of

                                       3
<PAGE>
 
          any securities received by holders of Class B Common Stock to the
          extent that the voting rights differ between shares of Class A Common
          Stock and shares of Class B Common Stock.

     (d)  Upon the voluntary or involuntary liquidation, dissolution or winding
          up of the Corporation, the net assets of the Corporation shall be
          distributed pro rata to the holders of Class A Common Stock and Class
          B Common Stock, without distinction as to class, in accordance with
          the number of shares held by each such holder.

     (e)  There shall be no preemptive rights in the holders of shares of Class
          A Common Stock or Class B Common Stock with respect to subscribing for
          or purchasing any part of any new or additional issue or sale or
          reservation of stock or securities of any class or kind whatsoever.

     (f)  Holders of Class A Common Stock and Class B Common Stock shall be
          entitled to receive, on an equal basis, such dividends payable in cash
          or otherwise, as may be declared thereon by the Board of Directors
          from time to time out of the assets or funds to the Corporation
          legally available therefor.  With respect to any dividends or
          distributions in cash, stock or property, each share of Class A Common
          Stock shall have rights equal to the rights of Class B Common Stock;
          provided, however, that in the case of dividends or distributions
          payable in Common Stock of the Corporation, such dividend or
          distribution must be made proportionately to the holders of Class A
          Common Stock and Class B Common Stock, either: (i) in Class A Common
          Stock to holders of both Class A Common Stock and Class B Common
          Stock; or (ii) in Class A Common Stock to holders of Class A Common
          Stock and in Class B Common Stock to holders of Class B Common Stock.

3.   Conversion of Class B Common Stock to Class A Common Stock.  Each share of
     ----------------------------------------------------------                
     Class B Common Stock may be converted, at any time and at the election of
     the holder, into one share of Class A Common Stock.  In addition, each
     share of Class B Common Stock shall be converted automatically into one
     share of Class A Common Stock at the time it is sold, transferred or
     otherwise disposed of to any third party other than a member of the Ketchum
     Group.  Upon any conversion of the Class B Common Stock into Class A Common
     Stock, the holder thereof shall be entitled to only one (1) vote per share
     on any matter submitted to the Stockholders for a vote.

                                   ARTICLE V
                                   ---------

     In furtherance and not in limitation of the powers conferred by statute,
the Board of Directors is expressly authorized:

1.   To adopt, amend or repeal the By-Laws of the Corporation.

2.   By a majority of the whole Board of Directors, to designate one (1) or more
     committees, each committee to consist of one (1) or more of the Directors
     of the Corporation.  The Board may designate one (1) or more Directors as
     alternate members of any committee, who may replace any absent or
     disqualified member at any meeting of the committee.  Any such committee,
     to the extent provided in the resolution or in the By-Laws of the
     Corporation, shall have and may exercise the powers of the Board of

                                       4
<PAGE>
 
     Directors in the management of the business and affairs of the Corporation,
     and may authorize the seal of the Corporation to be affixed to all papers
     which may require it; provided, however, the By-Laws may provide that in
     the absence or disqualification of any member of such committee or
     committees, the member of members thereof present at any meeting and not
     disqualified from voting, whether or not he or they constitute a quorum,
     may unanimously appoint another member of the Board of Directors to act at
     the meeting in the place of any such absent or disqualified member.

                                  ARTICLE VI
                                  ----------

     Whenever a compromise or arrangement is proposed between this Corporation
and its creditors or any class of them and/or between this Corporation and its
shareholders or any class of them, any court of equitable jurisdiction within
the State of Oklahoma, on the application in a summary way of this Corporation
or of any creditor or shareholder thereof, or on the application of any receiver
or receivers appointed for this Corporation under the provisions of Section 1106
of Title 18 of the Oklahoma Statutes or on the application of trustees in
dissolution or of any receiver or receivers appointed for this Corporation under
the provisions of Section 1100 of Title 18 of the Oklahoma Statutes may order a
meeting of the creditors or class of creditors, and/or of the shareholders or
class of shareholders of this Corporation, as the case may be, to be summoned in
such manner as the court directs. If a majority in number representing three-
fourths (3/4ths) in value of the creditors or class of creditors, and/or of the
shareholders or class of shareholders of this Corporation, as the case may be,
agree to any compromise or arrangement and to any reorganization of this
Corporation as a consequence of such compromise or arrangement, the compromise
or arrangement and the reorganization shall, if sanctioned by the court to which
the application has been made, be binding on all the creditors or class of
creditors and/or on all the shareholders or class of shareholders of this
Corporation, as the case may be, and also on this Corporation.

                                  ARTICLE VII
                                  -----------

or in the By-Laws of the Corporation. Elections of Directors need not be by
written ballot unless the By-Laws of the Corporation shall so provide.

                                 ARTICLE VIII
                                 ------------

     To the fullest extent permitted by the Oklahoma General Corporation Act as
the same exists or may hereafter be amended, a Director of this Corporation
shall not be liable to the Corporation or its shareholders for monetary damages
for breach of fiduciary duty as a Director. No amendment to or repeal of this
Article shall apply to or have any effect on the liability or alleged liability
of any Director of the Corporation for or with respect to any acts or omissions
of such Director occurring prior to such amendment or repeal.

                                  ARTICLE IX
                                  ----------

     2.04.  SPECIAL MEETINGS.  Special meetings of the Shareholders of the
     -----------------------                                              
Corporation may be called at any time by the President, the Chairman of the
Board, if any, or a majority of the Board of Directors, for any purpose or
purposes for which meetings may be lawfully called.  At any time, upon written
request of any person or persons who have duly called a special meeting, which
written request shall state the purpose or purposes of the meeting, it shall be
the duty of the President to fix the date of the meeting to be held at such date
and time as the President may fix, not less than ten (10) nor more than sixty
(60) days after the receipt of the request, and to give due notice thereof.  If
the President shall neglect or refuse to fix the time and date of such meeting
and give notice thereof, the person or persons calling the meeting may do so.

     SECTION 2.05.  NOTICE OF MEETINGS.  Written notice of the place, date and
     ---------------------------------                                        
hour of every meeting of the Shareholders, whether annual or special, shall be
given by the Chairman of the Board, the President, a Vice President, the
Secretary or an Assistant Secretary of the Corporation to each Shareholder
having voting power with respect to the business to be transacted at such
meeting, not less than ten (10) nor more than sixty (60) days before the date of
the meeting.  Each notice of a special meeting shall state the purpose or
purposes for which the meeting is being called.  Any meeting at which all
Shareholders having voting power with respect to the business to be transacted
thereat are present, either in person or by proxy, shall be a valid

                                       4
<PAGE>
 
meeting for the transaction of business, notwithstanding that notice has not
been given as hereinabove provided.

     SECTION 2.06.  QUORUM, MANNER OF ACTING AND ADJOURNMENT.  A quorum at all
     -------------------------------------------------------                  
meetings of the Shareholders for the transaction of business except as otherwise
provided by statute, by the Certificate of Incorporation or by these By-Laws,
shall consist of forty percent (40%) of the outstanding shares of common stock
(excluding treasury shares)  present in person or represented by proxy,
multiplied by the number of votes represented by those shares.  If, however,
such quorum shall not be present or represented at any meeting of the
Shareholders, the Shareholders entitled to vote thereat, present in person or
represented by proxy, shall have power to adjourn the meeting from time to time,
without notice other than announcement at the meeting, until a quorum shall be
present or represented.  At any such adjourned meeting at which a quorum shall
be present or represented, any business may be transacted which might have been
transacted at the meeting as originally notified.  If the adjournment is for
more than thirty (30) days or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each Shareholder of record having voting power with respect to the
business to be transacted at such meeting.  When a quorum is present at any
meeting, the vote of the holders of the majority of the votes represented by the
stock having voting power with respect to a question present in person or
represented by proxy shall decide any such question brought before such meeting,
unless the question is one upon

                                       5
<PAGE>
 
which, by express provision of the applicable statute or these By-Laws, a
different vote is required, in which case such express provision shall govern
and control the decision on such question. Except upon those questions governed
by the aforesaid express provisions, the Shareholders present in person or by
proxy at a duly organized meeting can continue to do business until adjournment,
notwithstanding withdrawal of enough Shareholders to leave less than a quorum.

     SECTION 2.07.  ORGANIZATION.  At every meeting of the Shareholders, the
     ---------------------------                                            
President, or in the absence of the President, one of the following persons
present in the order stated:  Chairman of the Board, if any; a chairman
designated by the Board of Directors, or a chairman chosen by the Shareholders,
shall act as chairman, and the Secretary, or in his absence, an Assistant
Secretary or a person appointed by the chairman of the meeting, shall act as
secretary of the meeting.

     SECTION 2.08.  VOTING, PROXIES.  Except as provided in the Certificate of
     ------------------------------                                           
Incorporation or in a resolution adopted by the Board of Directors pursuant to
Section 1032 of the Oklahoma General Corporation Act and subject to Section 1058
of such Act, each Shareholder shall at every meeting of the Shareholders be
entitled to vote in person or by proxy each share of capital stock having voting
power held by such Shareholder.  No proxy shall be voted after three (3) years
from its date, unless the proxy provides for a longer period.  Each proxy shall
be executed in writing by the Shareholder or by his duly authorized attorney-in-
fact and filed with the Secretary of the Corporation or the

                                       6
<PAGE>
 
secretary of the meeting prior to being voted. A proxy, unless coupled with an
interest, shall be revocable at will, notwithstanding any other agreement or any
provision in the proxy to the contrary, but the revocation of a proxy shall not
be effective until notice thereof has been given to the Secretary of the
Corporation. A duly executed proxy shall be irrevocable if it states that it is
irrevocable and if, only as long as, it is coupled with an interest sufficient
in law to support an irrevocable power. A proxy may be made irrevocable
regardless of whether the interest with which it is coupled is an interest in
the stock itself or an interest in the Corporation generally. A proxy shall not
be revoked by death or incapacity of the maker unless, before the vote is
counted or the authority is exercised, written notice of such death or
incapacity is given to the Secretary of the Corporation.

     SECTION 2.09.  ACTION BY SHAREHOLDERS IN LIEU OF MEETING.  Any action which
     --------------------------------------------------------                   
may be or is required to be taken at an annual or special meeting of the
Shareholders of the Corporation may be taken without a meeting, without prior
notice and without a vote, only if all of the Shareholders of the Corporation
entitled to vote thereon consent to such action in writing.

     SECTION 2.10.  VOTING LISTS.  The officer who has charge of the stock
     ---------------------------                                          
ledger of the Corporation shall prepare and make, at least ten (10) days before
every meeting of Shareholders, a complete list of the Shareholders entitled to
vote at the meeting.  The list shall be arranged in alphabetical order and show
the address of each Shareholder and the number of shares

                                       7
<PAGE>
 
registered in the name of each Shareholder. Such list shall be open to the
examination of any Shareholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting either at a place within the city where the meeting is to be held, which
place shall be specified in the notice of the meeting, or, if not so specified,
at the place where the meeting is to be held. The list shall also be produced
and kept at the time and place of the meeting during the whole time thereof and
may be inspected by any Shareholder who is present.

included in the Corporation's proxy statement soliciting proxies for the
nominee's election as a Director.  Nominations, other than those made by or at

          anniversary date, not later than the tenth (10th) day following the

     (4)  The principal occupation or employment of each such nominee;

          beneficially owned by each such nominee;

     (6)  Such other information concerning each such nominee as would be

          a proxy statement soliciting proxies for the election of such
          nominees;

     (7)  A description of all arrangements or understandings between such
          Shareholder and any other person or persons (including their names) in

Such notice shall include a signed consent of each such nominee to serve as a
Director of the Corporation, if elected.  The Corporation shall not be obligated
to include in its proxy materials any person who is nominated by a Shareholder
as a candidate for election as a Director.  In the event that a person who is
validly designated as a nominee in accordance with this Section shall thereafter
become unable or unwilling to stand for election to the Board of Directors, the
Board of Directors may designate a substitute nominee.  If the Chairman of the
meeting determines that a nomination was not made in accordance with the
foregoing procedures, such nomination shall be void.

majority of the members of any committee who are present at any meeting thereof
at which a quorum is present shall be the act of such committee. Any vacancy in
any committee shall be filed by a vote of a majority of the Directors at the
time in office.

     Any such committee to the extent provided in the resolution establishing
such committee shall have and may exercise all the power and authority of the
Board of Directors in the management of the business and affairs of the

of Directors in reference to amending the Certificate of Incorporation,

of its meetings and its own rules of procedure and shall keep regular minutes of
its meetings and report from time to time to the Board of Directors.

the Certificate of Incorporation, the Board of Directors shall have the
authority to fix the compensation of Directors.  The Directors may be paid their
expenses, if any, of attendance at each meeting of the Board of Directors and
may be paid a fixed sum for attendance at each meeting of the Board of Directors
or a stated salary as Director.  No such payment shall preclude any Director
from serving the Corporation in any other capacity and receiving compensation
therefor.  Members of special or standing committees may be allowed like
compensation for attending committee meetings.

     SECTION 3.17.  HOLDERS OF PREFERRED STOCK.  Notwithstanding the foregoing,

not precede the date upon which the resolution fixing the record date is adopted
by the Board of Directors, and which date shall not be more than ten (10) days
after the date upon which the resolution fixing the record date is adopted by
the Board of Directors. If no record date has been fixed by the Board of
Directors, the record date for determining Shareholders entitled to consent to

                                  -----------

     SECTION 7.01. INDEMNIFICATION OF AUTHORIZED REPRESENTATIVES IN THIRD PARTY
     --------------------------------------------------------------------------
PROCEEDINGS.  The Corporation shall indemnify any person who was or is an
- -----------                                                              
"authorized representative" of the Corporation (which shall mean for purposes of
this Article VII a Director, officer, employee or agent of the Corporation, or a
person serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise) and who was or is a "party" (which shall include for purposes
of this Article VII the giving of testimony or similar involvement) or is
threatened to be made a party to any "third party proceeding" (which shall mean
for the purposes of this Article VII any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative, other than an action by or in the right of the Corporation) by
reason of the fact that such person was or is an authorized representative of
the Corporation, against expenses (which shall include for purposes of this
Article VII attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such third
party proceeding if such person acted in good faith and in a manner such person
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal third party proceeding, had no
reasonable cause to believe such conduct was unlawful. The termination of any
third party proceeding by judgment, order, 

                                       30
<PAGE>
 
settlement, indictment, conviction or upon a plea of nolo contendere or its
equivalent, shall not of itself create a presumption that the authorized
representative did not act in good faith and in a manner which such person
reasonably believed to be in or not opposed to, the best interests of the
Corporation, or, with respect to any criminal third party proceeding, did not
have reasonable cause to believe that such conduct was unlawful.

     SECTION 7.02.  INDEMNIFICATION OF AUTHORIZED REPRESENTATIVES IN CORPORATE
     -------------------------------------------------------------------------
PROCEEDINGS.  The Corporation shall indemnify any person who was or is an
- -----------                                                              
authorized representative of the Corporation and who was or is a party or is
threatened to be made a party to any "corporate proceeding" (which shall mean
for purposes of this Article VII any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor or
investigative proceeding by the Corporation) by reason of the fact that such
person was or is an authorized representative of the Corporation, against
expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection with the defense or settlement of such corporate proceeding
if such person acted in good faith and in a manner reasonably believed to be in,
or not opposed to, the best interests of the Corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that a district court or the court in which such
corporate proceeding was pending shall 

                                       31
<PAGE>
 
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such authorized representative is
fairly and reasonably entitled to indemnity for such expenses which the district
court or such other court shall deem proper.

     SECTION 7.03.  MANDATORY INDEMNIFICATION OF AUTHORIZED REPRESENTATIVES.  To
     ----------------------------------------------------------------------     
the extent that an authorized representative of the Corporation has been
successful on the merits or otherwise in defense of any third party or corporate
proceeding referred to in Sections 7.01 or 7.02 above or in defense of any
claim, issue or matter therein, such person shall be indemnified against
expenses, including attorneys' fees, actually and reasonably incurred by such
person in connection therewith.

     SECTION 7.04  DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION.  Any
     -------------------------------------------------------------      
indemnification under Sections 7.01, 7.02 or 7.03 of this Article VII (unless
ordered by a court) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of the authorized
representative is proper in the circumstances because such person has met the
applicable standard of conduct set forth in Sections 7.01, 7.02 or 7.03 of this
Article VII.  Such determination shall be made:

     A.   By the Board of Directors by a majority of a quorum consisting of
          Directors who were not parties to such action, suit or proceeding; or

     B.   If such a quorum is not obtainable, or, even if obtainable, a quorum
          of disinterested Directors so 

                                       32
<PAGE>
 
          directs, by independent legal counsel in a written opinion; or

     C.   By the Shareholders.

     SECTION 7.05.  BURDEN OF PROOF.  In the event a claim for indemnification
     ------------------------------                                           
by an authorized representative is denied by the Corporation (except for a claim
by a person described in Section 7.08 hereof), the Corporation shall, in any
subsequent legal proceedings relating to such denial, have the burden of proving
that indemnification was not required under Sections 7.01, 7.02 or 7.03 of these
By-Laws without regard to Section 7.04 hereof or under any other agreement or
undertaking between the Corporation and the authorized representative or was not
permitted under applicable law.

     SECTION 7.06.  ADVANCING EXPENSES.  Expenses incurred by an officer or
     ---------------------------------                                     
Director in defending a third party or corporate proceeding shall be paid by the
Corporation in advance of the final disposition of such third party or corporate
proceeding upon receipt of an undertaking by or on behalf of such officer or
Director to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the Corporation as authorized in
this Article VII.  Such expenses incurred by other employees and agents may be
so paid upon such terms and conditions, if any, as the Board of Directors deems
appropriate.

     SECTION 7.07.  EMPLOYEE BENEFIT PLANS.  For purposes of this Article VII,
     -------------------------------------                                    
the Corporation shall be deemed to have requested an authorized representative
to serve an employee benefit plan where

                                       33
<PAGE>
 
the performance by such person of duties to the Corporation also imposes duties
on, or otherwise involves services by, such person to the plan or participants
or beneficiaries of the plan; excise taxes assessed on an authorized
representative with respect to an employee benefit plan pursuant to applicable
law shall be included within the meaning of "fines;" and action taken or omitted
by such person with respect to an employee benefit plan in the performance of
duties for a purpose reasonably believed to be in the interest of the
participants and beneficiaries of the plan shall be deemed to be for a purpose
which is not opposed to the best interests of the Corporation.

     SECTION 7.08.  PERSONS OTHER THAN AUTHORIZED REPRESENTATIVES.  The
     ------------------------------------------------------------      
Corporation may, but is not required to, indemnify any person who is not also an
authorized representative if the determining group as specified in Section 7.04
A, B or C determines that such indemnification is proper in the specific case.

     SECTION 7.09.  SCOPE OF ARTICLE.  The indemnification of and advancement of
     -------------------------------                                            
expenses to any authorized representatives, as authorized by this Article VII,
shall not be deemed  exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any by-law,
agreement, vote of Shareholders or disinterested Directors or otherwise, both as
to action in an official capacity and as to action in another capacity while
holding such office.

     SECTION 7.10. RELIANCE ON PROVISIONS.  Each person who shall act as an
     ------------------------------------                                  
authorized representative of the Corporation shall be 

                                       34
<PAGE>
 
deemed to be doing so in reliance upon rights of indemnification provided by
this Article VII, and the provisions of this Article VII shall be deemed a
contract between the Corporation and the authorized representative.

     SECTION 7.11.  INSURANCE.  The Corporation shall have the power to, but
     ------------------------                                               
shall not be obligated to, purchase and maintain insurance on behalf of any
person who is or was an authorized representative of the Corporation, or is or
was serving at the request of the Corporation as an authorized representative or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against such person and incurred by
such person in any capacity, or arising out of such person's status as such,
whether or not the Corporation would have the power to indemnify such person
against such liability under the provisions of this Article VII.

     SECTION 7.12.  RIGHTS CONTINUE.  The indemnification and advancement of
     ------------------------------                                         
expenses provided by or granted pursuant to this Article VII, unless otherwise
provided when authorized or ratified, shall continue as to a person who has
ceased to be an authorized representative and shall inure to the benefit of the
heirs, executors and administrators of such a person.

     SECTION 7.13.  REFERENCES TO CORPORATION.  For purposes of this Article
     ----------------------------------------                               
VII, references to "the Corporation" shall be deemed to include all constituent
corporations absorbed in a consolidation or merger, as well as the resulting or
surviving corporation so that any person who is or was a director, officer,
employee or agent of such a constituent corporation or is or was 

                                       35
<PAGE>
 
serving at the request of such constituent corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
enterprise shall stand in the same position under the provisions of this Article
VII with respect to the resulting or surviving corporation in the same capacity.

                                 ARTICLE VIII
                                 ------------

be declared by the Board of Directors at any regular or special meeting, in

sums as the Board of Directors from time to time, in its absolute discretion,
thinks proper as a reserve or reserves to meet contingencies, or for repairing
or maintaining any property of the Corporation, or for such other purpose as the

the Board of Directors may modify or abolish any such reserve in the manner in
which it was created.

Directors may from time to time designate.

     SECTION 8.05.  CORPORATE SEAL.  The corporate seal shall have inscribed

IMPORTANT NOTICE:  When you sign your name to this Assignment Form without
filling in the name of your "Assignee" or "Attorneys," this stock certificate
becomes fully negotiable, similar to a check endorsed in blank.  Therefore, to
safeguard a signed certificate, it is recommended that you either (i) fill in
the name of the new owner in the "Assignee" blank or (ii) if you are sending the
certificate to your bank or broker, fill in the name of the bank or broker in
the "Attorney" blank.  Alternatively, instead of using this Assignment Form, you
may sign a separate "stock power" form (available from New York Stock Exchange,
commercial bank or trust company) and then mail the unsigned stock certificate
and the signed "stock power" in separate envelopes.  For added protection, use
certified or registered mail for a stock certificate.  If you have any questions
on the transfer procedure, please call the Registrar and Transfer Agent listed
on the face of this certificate.

Officers, Directors and key employees of the Company or any Subsidiary who shall

                                   SECTION 6
                                   ---------
                        TERMS AND CONDITIONS OF OPTIONS
                        -------------------------------

     The Administrator may, in its discretion, grant Options to any Participant
under the Plan.  Each Option shall be evidenced by a written agreement between
the Company and the Participant.  Unless the Administrator at the time of grant
specifically designates Options granted under the Plan as Incentive Stock
Options, all Options granted under the Plan shall be non-statutory options.
Each Option agreement, in such form as is approved by the Administrator, shall
be subject to the following express terms and conditions and to such other terms
and conditions, not inconsistent with the Plan as the Administrator may deem
appropriate:

     A.    Option Period: Each Option granted under the Plan shall be for such
           period as is established by the Board, except that each ISO shall
           expire no later than ten (10) years after the Option Date. Where
           Options are exercisable in installments, the right to purchase any
           shares shall be cumulative, so that when the right to purchase any
           shares has matured, such shares may be purchased thereafter until the
           expiration of the Option. The Board shall have the power to
           accelerate the exercisability of installments for any Option granted
           under the Plan.

     B.    Option Price: At the time when the Option is granted, the
           Administrator will fix the Option Price; provided, however, that the
           Option price shall be no less than the Fair Market Value on the
           Option Date.

                                       4
<PAGE>
 
     C.    Incentive Stock Options: ISO's may only be granted to employees of
           the Company or of a Subsidiary. No more than five thousand (5,000)
           shares of the Company's Class A Common Stock may be issued upon the
           exercise of ISO's granted under this Plan and no ISO may be granted
           under the Plan after the tenth (10th) anniversary of the date the
           Plan is approved by the shareholders of the Company. The aggregate
           Fair Market Value (determined as of the Option Date of the ISO) of
           the Common Stock with respect to which ISO's are first exercisable by
           a Company or Subsidiary employee during any calendar year under all
           Option Plans of the Company shall not exceed One Hundred Thousand
           Dollars ($100,000). An ISO granted to an employee who, at the time
           the ISO is granted, owns Common Stock possessing more than ten
           percent (10%) of the total combined voting power of all classes of
           capital stock of the Company or a Subsidiary thereof, shall have an
           exercise price equal to not less than one hundred ten percent (110%)
           of the Fair Market Value on the Option Date. Notwithstanding any
           other provision of this Plan, an ISO shall not be transferable or
           assignable otherwise than by will or the laws of descent and
           distribution. Any Participant who disposes of shares acquired upon
           the exercise of an ISO either (i) within two (2) years after the
           Option Date of the Option under which the shares were acquired, or
           (ii) within one (1) year after the acquisition of such shares shall
           notify the Company of such disposition and of the amount realized.
           Failure by a Participant to so notify the Company of such a
           disposition of shares shall entitle the Company to treat the shares
           of Common Stock issued to such Participant as void ab initio or to
           recover from the Participant the greater of the value of the shares
           disposed of as of the date of disposition or the value of the shares
           disposed of as of the date the Company learns of such disposition
           from either (i) any amounts due to such Participant from the Company
           or a Subsidiary, or (ii) otherwise. The Company may, at its
           discretion, place a legend noting the possible consequences of a
           Participant's failure to provide such disposition notice on shares of
           Common Stock delivered upon the exercise of an ISO.

     E.    No person shall have any rights of a shareholder with respect to any
           shares to be delivered upon the exercise of an Option until such time
           as such Option is validly exercised.

                                   SECTION 7
                                   ---------
                TERMS AND CONDITIONS OF RESTRICTED STOCK AWARDS
                -----------------------------------------------

     The Administrator may grant Restricted Stock to any Participant under the
Plan, the purchase price of which shall be established by the Administrator,
which purchase price may be financed by the Company on terms established by the
Administrator.  Each grant of Restricted Stock shall be evidenced by an Award
Agreement between the Company and the Participant.  All shares of Common Stock
awarded to Participants under the Plan as Restricted Stock shall be subject to
the following express terms and conditions and to such other terms and
conditions, not inconsistent with the Plan, as the Board shall deem appropriate:

     A.    Restrictions on Transfer:  Shares of Restricted Stock awarded to
           Participants shall contain such restrictions on transfer as the Board
           may determine in its sole discretion.  Except as may be

                                       5
<PAGE>
 
           permitted under Section 11 of the Plan, shares of Restricted Stock
           awarded to Participants may not be sold or transferred before such
           restrictions on transfer lapse, and may only be pledged to the
           Company or any Subsidiary to satisfy any obligations that the
           Participant may have to the Company or the Subsidiary with respect to
           the acquisition of such shares of Restricted Stock. Subject to the
           provisions of subparagraphs B and C below and any other restrictions
           imposed by law, the certificates for any shares of Restricted Stock,
           the restrictions on which have lapsed, will be transferred to the
           Participant, or in the event of his death, to the beneficiary or
           beneficiaries designated by writing filed by the Participant with the
           Board for such purpose or, if none, to his estate. Delivery of shares
           in accordance with the preceding sentence shall be made within the
           thirty (30) day period after such restrictions shall lapse.

     B.    Certificates Deposited with Company: Each certificate issued in
           respect of shares of Restricted Stock awarded under the Plan shall be
           registered in the name of the Participant and deposited with the
           Company. Each such certificate shall bear the following (or a
           similar) legend:

               "The transferability of this certificate and the shares of stock
               represented hereby are subject to the terms and conditions
               (including forfeiture) relating to Restricted Stock contained in
               the Red Man Pipe & Supply Co. Incentive Stock Plan 1997 and an
               agreement entered into between the registered owner and Red Man
               Pipe & Supply Co.  Copies of such Plan and Agreement are on file
               at the principal office of Red Man Pipe & Supply Co."

     C.    Shareholder Rights: Subject to the foregoing restrictions, each
           Participant shall have all the rights of a shareholder with respect
           to his shares of Restricted Stock, including, but not limited to, the
           right to vote such shares.

     D.    Dividends: On each Common Stock dividend payment date, each
           Participant shall receive an amount equal to the dividend paid on
           that date on a share of Common Stock, multiplied by his number of
           shares of Restricted Stock.

                                   SECTION 8

                         DEFERRAL OF RECEIPT OF SHARES
                         -----------------------------

     To exercise an Option in whole or in part, a Participant (or, after his
death, his executor or administrator) or his assignee (as contemplated in
Section 11 hereof) must give written notice to the Administrator, or the person
designated by the Administrator, stating the number of shares with respect to
which he intends to exercise the Option.  The Company will issue the shares with
respect to which the Option is exercised upon payment in full of the Option
Price.  The Option Price may be paid:

     A.    In cash;

     B.    In shares of Common Stock held by the Participant, his executor,
           administrator or assignee, and having an aggregate Fair Market Value,
           as determined as of the close of business on the day on which such
           Option is exercised, equal to the Option Price;

                                       6
<PAGE>
 
     C.   If permitted by the Administrator, a promissory note in the amount of
          the Option Price, which note shall provide for full personal liability
          of the maker and shall contain such other terms and provisions as the
          Administrator may determine, including without limitation the right to
          repay the note partially or wholly with Common Stock;

     D.   If authorized by the Administrator in the Award Agreement for the
          Option being exercised, by delivery of irrevocable instructions to a
          broker to promptly deliver to the Company the amount of sale or loan
          proceeds necessary to pay for all Common Stock acquired through such
          exercise and any tax withholding obligations resulting from such
          exercise;

     E.   If authorized by the Administrator in the Award Agreement for the
          Option being exercised, by the withholding by the Company, pursuant to
          a written election delivered by the Participant, his executor,
          administrator or assignee, to the Administrator on or prior to the
          date of exercise, from the shares of Common Stock issuable upon any
          exercise of the Option that number of shares having a Fair Market
          Value as of the close of business on the day on which such Option is
          exercised equal to such Option Price;

     F.   As authorized by the Administrator in the Award Agreement for the
          Option being exercised, by a combination of such methods.

                                   SECTION 9

                                    -------

     A Participant may not exercise an Option until it has become vested.  The
portion of an Option Award that is vested depends upon the vesting restrictions,
if any, established by the Administrator for such Option at the time of its
grant and the period that has elapsed since the Option Date.

                                  SECTION 10
                                  ----------
              ADJUSTMENTS TO REFLECT CHANGES IN CAPITAL STRUCTURE
              ---------------------------------------------------

     If there is any change in the corporate structure or shares of the Company,
adjustments will be made as necessary to prevent accretion, or to protect
against dilution, in the number and kind of shares authorized by the Plan and,
with respect to outstanding Options and/or Restricted Stock, in the number and
kind of shares covered thereby and in the applicable Option Price.  For the
purpose of this Section 10, a change in the corporate structure or shares of the
Company includes, without limitation, any change resulting from a
recapitalization, stock split, stock dividend, consolidation, rights offering,
spin-off, reorganization or liquidation and any transaction in which shares of
Common Stock are changed into or exchanged for a different number or kind of
shares of stock or other securities of the Company or another corporation.

A.   Unless otherwise expressly provided in this Section 11, by applicable law
     or by any Award Agreement, as the same may be amended, evidencing the grant
     or award of Restricted Stock or Options, Awards are non-transferable and
     shall not be subject in any manner to sale, transfer, anticipation,
     alienation, assignment, pledge, encumbrance or charge.  Awards shall be
     exercised only by the person to whom such Awards were

                                       7
<PAGE>
 
     granted or awarded (a "Recipient") and amounts payable or shares issuable
     pursuant to Awards shall be delivered only to or for the account of a
     Recipient.

B.   Except as precluded by any applicable law, the Administrator may permit
     Awards to be transferred to and exercised by and paid to certain persons or
     entities related to the Recipient, including but not limited to members of
     the Recipient's immediate family (parents, grandparents, children,
     grandchildren, spouse, siblings), charitable institutions or trusts or
     other entities whose beneficiaries or beneficial owners are members of the
     Recipient's immediate family and/or charitable institutions, or to such
     other persons or entities as may be approved by the Administrator, pursuant
     to such conditions and procedures as the Administrator may establish.  Any
     permitted transfer shall be subject to the condition that the Administrator
     receive evidence satisfactory to it that the transfer is being made for
     estate and/or tax planning purposes on a gratuitous or donative basis and
     without consideration other than nominal consideration.

C.   The exercise and transfer restrictions in this Section 11 shall not apply
     to:

     (1)  Transfers to the Company;

     (2)  The designation of a beneficiary to receive benefits in the event of
          the Recipient's death or, if the Recipient has died, transfers to or
          exercise by the Recipient's beneficiary, or, in the absence of a
          validly designated beneficiary, transfers by will or the laws of
          descent and distribution;

     (3)  Transfers pursuant to a domestic relations order;

     (4)  If the Recipient has suffered a disability, permitted transfers or
          exercises on behalf of the Recipient by his or her legal
          representative; or

     (5)  The authorization by the Administrator of "cashless exercise"
          procedures with third parties who provide financing for the purpose of
          (or who otherwise facilitate) the exercise of Awards consistent with
          applicable laws and the express authorization of the Administrator.

D.   In the event of a transfer of an Award pursuant to Subsection B or C of
     this Section 11, the Recipient will remain liable for any taxes (including
     withholding and social security taxes) due upon or as a consequence of the
     exercise of or lapse of any restrictions in respect of an Award and neither
     the Company nor the Administrator shall have any obligation to provide
     notice to a transferee of any event or information that has, will or could
     in any way affect an Award or its exercise.

                                  SECTION 12
                                  ----------
                             RIGHTS AS SHAREHOLDER
                             ---------------------

     No person shall have any rights of a shareholder as to shares of Common
Stock subject to an Award under the Plan until, after proper exercise of the
Award or other action required, such shares shall have been recorded on the
Company's official shareholder records as having been issued or transferred.
Upon exercise of the Award or any portion thereof, the Company will have thirty
(30) days in which to issue the shares, and the Participant will not be treated
as a shareholder for any purpose whatsoever prior to such issuance.  No
adjustment shall be made for cash dividends or other rights for which the

                                       8

record date is prior to the date such shares are recorded as issued or
transferred in the Company's official shareholder records, except as provided
herein or in an Agreement.

                                  SECTION 13
                                  ----------
                                WITHHOLDING TAX
                                ---------------

     Upon the exercise of an Option, or the lapse of restrictions on Restricted
Stock, requiring tax withholding, the Participant will be required to pay to the
Company for remittance to the appropriate taxing authorities an amount necessary
to satisfy the employee's portion of federal, state and local taxes, if any,
incurred by reason of the exercise of an Option or the lapse of such
restrictions.  A Participant may elect to have any tax withholding obligation
incurred upon the exercise of or lapse of restrictions in respect of an Award
satisfied by payment of cash by the Participant, by the withholding of cash
otherwise due the Participant, or, except in the case of ISO's, by the
withholding of shares of Common Stock issuable upon such occurrence and having
an aggregate Fair Market Value on the day prior to the day of exercise or lapse
sufficient to satisfy the applicable tax withholding requirement; provided,
however, that if the Participant elects to have shares of Common Stock withheld
from the shares deliverable upon such exercise or lapse, a Participant's
election must be delivered to the Administrator in writing on or prior to the
date of exercise of the Options or lapse of restrictions with respect to
Restricted Stock.

                                  SECTION 14
                                  ----------
                           TERMINATION OF EMPLOYMENT
                           -------------------------

     In the event of a Participant's Termination of Employment, the following
rules shall apply:

     A.   Resignation in order to assume employment, approved by the Company's
          Chief Executive Officer, with a governmental, charitable or
          educational institution, or business entity affiliated with the
          Company:  When a Participant resigns to assume employment, approved by
          the Company's Chief Executive Officer, with a governmental, charitable
          or educational institution, or business entity in which the Company
          has an equity interest, the Administrator may (i) authorize the
          continuation of Options granted or Restricted Stock awarded prior to
          termination as if the Participant were still employed by the Company
          and (ii) permit the exercise of such Options or lapse of restrictions
          in respect of Restricted Stock during periods after such Termination
          of Employment, but not beyond the original expiration date of the
          Option.  Such actions will not be authorized to the extent they would
          cause outstanding ISO's to be considered to have been modified for
          purposes of Section 424(h) of the Code.  Unless the Administrator
          determines otherwise, termination of such approved employment, except
          to rejoin the Company or accept other employment which would qualify
          under this Paragraph A, or divestiture by the Company of its equity
          interest in such business entity, shall be treated as a termination of
          employment pursuant to Paragraphs B, C or D of this Section 14.

     B.   Termination of Employment for any reason other than death, disability
          or resignation for approved employment pursuant to Paragraph A of this
          Section 14:  Any Option or Restricted Stock shall expire forthwith;
          provided, however, that with the approval of the Board evidenced by a
          writing signed by an executive officer

                                       9
<PAGE>
 
          of the Company other than the Participant, unvested Options may be
          accelerated to vest immediately; any Options exercisable at the time
          of such termination may be exercised up to a date after such
          termination that is determined by the Board, but not exceeding five
          (5) years from the date of such termination and not beyond the date
          the Option otherwise would have expired in accordance with the Award
          Agreement evidencing such Option and/or the restrictions on Restricted
          Stock may be eliminated so that such Restricted Stock is free of such
          restrictions at the time of Termination of Employment and not
          forfeited upon such Termination of Employment.

     C.   Death of a Participant:  A Participant's estate or beneficiaries shall
          have a period up to the later of one (1) year after the Participant's
          death or the expiration date specified in the Award Agreement within
          which to exercise the Option; provided, however, in the case of ISO's,
          the Participant's estate or beneficiaries may exercise an Option only
          until the expiration date specified in the Award Agreement.  Any
          Option may be immediately exercised in full by the Participant's
          estate or beneficiaries.  In the event the Participant's estate is
          closed with exercisable Options then unexercised, the rights under
          this Paragraph shall pass by will or the laws of descent and
          distribution.  In the case of Restricted Stock, the restrictions on
          such Restricted Stock shall be deemed to have lapsed immediately
          before such Participant's death.

     D.   Disability of a Participant:  In the event of a Participant's
          Disability during employment, the Participant, or his or her guardian
          or legal representative, shall have a period up to the expiration date
          specified in the Award Agreement within which to exercise the Option.
          In the case of Restricted Stock, the restrictions on such Restricted
          Stock shall be deemed to have lapsed immediately before the
          Termination of Employment of such Participant.

                                  SECTION 15
                                  ----------
                            NO RIGHT TO EMPLOYMENT
                            ----------------------

     Participation in the Plan will not give any Participant a right to be
retained as an employee of the Company or any Subsidiary, or any right or claim
to any benefit under the Plan, unless the right to claim has specifically
accrued under the Plan.

                                  SECTION 16
                                  ----------
                             AMENDMENT OF THE PLAN
                             ---------------------

     Except as provided in this Section 16, the Board may amend, modify, suspend
or discontinue this Plan for the purpose of meeting any changes in legal
requirements or for nay other purpose permitted by law.  Except for any
adjustments pursuant to Section 10, the Board may not:

     A.   Increase the maximum number of shares that may be issued under the
          Plan; or

     B.   Decrease the exercise price with respect to any Option previously
          granted.

The Board may from time to time amend or revise the terms of the Plan in whole
or in part and may, without limitation, adopt any amendment deemed necessary.

                                    NOTICE
                                    ------

     Any written notice to the Company required by any of the provisions of the
Plan shall be addressed to the Administrator, if so required under the Plan, and
otherwise to the Chairman of the Board or to the Chief Executive Officer of the
Company, and shall become effective when it is received by the office of such
Administrator, Chairman or the Chief Executive Officer.

                                  SECTION 18

                    COMPANY BENEFIT AND COMPENSATION PLANS
                    --------------------------------------

     Nothing contained in the Plan shall prevent any Participant prior to death,
or the Participant's dependents or beneficiaries after the Participant's death,
from receiving, in addition to any Options or Restricted Stock provided for
under the Plan, any salary, incentive or performance plan Awards, payments under
a Company retirement plan or other benefits that may be otherwise payable or
distributable to such Participant, or to the Participant's dependents or
beneficiaries under any other plan or policy of the Company or otherwise.  To
the extent permitted by law, grants of Options or awards of Restricted Stock
under the Plan may be made in combination with, or as alternatives to, grants,
Awards or payments under other Company plans.

                                  ----------
                        REPRESENTATIONS AND WARRANTIES
                        ------------------------------

     No person shall at any time have a right to be selected as a Participant in
the Plan, nor having been selected as a Participant for one Award, to be
selected as a Participant for any other Award, and no person shall have any
authority to enter into any agreement assuring such selection or making any
warranty or representation with respect thereto.  A Participant shall have no
rights to or interest in any Option or Restricted Stock except as set forth
therein.

                                  SECTION 20
                                  ----------
                                 UNFUNDED PLAN
                                 -------------

     Insofar as it provides for grants of Options and Awards of Restricted
Stock, the Plan shall be unfunded.  Although bookkeeping accounts may be
established with respect to Participants who are or may become entitled to
Common Stock under the Plan, any such accounts shall be used merely as a
bookkeeping convenience.  The Company shall not be required to segregate any
assets that may at any time be represented by Common Stock, nor shall the Plan
be construed as providing for such segregation, nor shall the Company nor the
Board be deemed to be a trustee of any Common Stock issuable or deliverable
under the Plan.  Any liability of the Company to a Participant with respect to a
grant of Options or award of Restricted Stock under the Plan shall be based
solely upon any contractual obligations that may be created by the Plan or an
Award Agreement; no such obligation of the Company shall be deemed to be secured
by any pledge or other encumbrance on any property of the Company.  Neither the
Company nor the Board shall be required to give any security or bond for the
performance of any obligation that may be created by the Plan.

                                  SECTION 21

                             SHAREHOLDER APPROVAL
                             --------------------

     Continuance of the Plan, and the validity of any Options granted or
Restricted Stock awarded under the Plan, shall be subject to approval by the
shareholders of the Company of the Plan within twelve (12) months after the date
the Plan is adopted by the Board.

                      CONDITIONS UPON ISSUANCE OF SHARES
                      ----------------------------------

     An Option shall not be exercisable, a share of Common Stock shall not be
issued pursuant to the exercise of an Option, and restrictions on Restricted
Stock awarded shall not lapse until such time as the Plan has been approved by
the shareholders of the Company and unless the Award of Restricted Stock,
exercise of such Option and the issuance and delivery of such share pursuant
thereto shall comply with all relevant provisions of law, including without
limitation, the Securities Act, the Exchange Act, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the shares of Common Stock may then be listed, and shall be further subject to
the approval of counsel for the Company with respect to such compliance.  As a
condition to the exercise of an Option, the Company may require the person
exercising such Option to represent and warrant at the time of any such exercise
that the Common Stock is being purchased only for investment and without present
intention to sell or distribute such shares if, in the opinion of counsel for
the Company, such a representation is required by any of the aforementioned
relevant provisions of law.

                    EFFECTIVE DATE AND TERMINATION OF PLAN
                    --------------------------------------

A.   Effective Date:  The Plan is effective as of the date of its adoption by
     the Board, subject to its approval by the Shareholders of the Company,
     pursuant to Section 21 hereof.

B.   Termination of the Plan:  The Board may terminate the Plan at any time with
     respect to any shares that are not then subject to Options or Restricted
     Stock.  Termination of the Plan will not affect the rights and obligations
     of any Participant with respect to Options or Restricted Stock awarded
     before termination.

SECTION 2.  CREDIT FACILITY

     2.1.  THE LOANS.  Provided that no Default or Event of Default has
occurred, Lender will make Loans on a revolving credit basis to Borrower from
time to time, in amounts as requested by Borrower, up to a maximum principal
amount at any time outstanding equal to the Borrowing Base at such time.  It is
expressly understood and agreed that Lender may use the Borrowing Base as a
maximum ceiling on Loans outstanding to Borrower at any time.  If the unpaid
balance of the Loans should exceed the Borrowing Base or any other limitation
set forth in this Agreement, such Loans shall nevertheless constitute
obligations that are secured by the Collateral and entitled to all benefits
thereof.  Insofar as Borrower may request and Lender may be willing in its
discretion to make Loans to Borrower at a time when the unpaid balance of Loans
exceeds, or would exceed with the making of any such Loan, the Borrowing Base
(any such Loan or Loans being herein referred to individually as an
"Overadvance" and collectively as "Overadvances"), Lender shall enter such
Overadvances as debits in the Loan Account.  All Overadvances shall be repaid ON
DEMAND.  In consideration of Lender making any Overadvance to Borrower, Borrower
agrees to pay to Lender, contemporaneously with the making of such Overadvance,
an amount equal to one percent (1%) of the Overadvance, provided that the
payment of such amount does not cause the interest on the obligations to exceed
the Maximum Legal Rate.  The Loans shall be used solely (i) for the satisfaction
of existing Indebtedness of Borrower to F&M Bank and Trust Company of Tulsa,
Oklahoma, (ii) for the satisfaction of certain trade payables and other
unsecured indebtedness owed to trade creditors of Borrower, (iii) for Borrower's
general operating capital needs to the extent not inconsistent with the
provisions of this Agreement, and (iv) for the payment of any of the fees
specified in Section 3.2 of this Agreement and, to the extent approved by
Lender, to the payment of any costs associated with the closing of the
transactions contemplated by this Agreement.

     2.2.  ALL LOANS TO CONSTITUTE ONE OBLIGATION.  All Loans shall constitute
one general obligation of Borrower, and shall be secured by Lender's security
interest in and Lien upon all of the Collateral, and by all other security
interests and Liens heretofore, now or at any time or times hereafter granted by
Borrower to Lender.

     2.3.  LOAN ACCOUNT.  Lender shall enter all Loans as debits to the Loan
Account and shall also record in the Loan Account all payments made by Borrower
on any Obligations and all proceeds of Collateral which are finally paid to
Lender, and may record therein, in accordance with customary accounting
practice, other debits and credits, including all charges and expenses properly
chargeable to Borrower and any other Obligation.

     2.4.  INCREASED COSTS AND CAPITAL.

     (A) If either (i) the introduction of or any change (including, without
limitation, any change by way of imposition or increase of reserve requirements)
in or in the interpretation of any law or regulation or (ii) the compliance by
Lender with any guideline or request from any central bank or other governmental
authority (whether or not having the force of law), shall result in any increase
in the cost to Lender of making, funding or maintaining any Loans, then Borrower
agrees to pay, from time to time, upon demand by Lender, to Lender additional
amounts sufficient to indemnify Lender against such increased cost.  A
certificate as to the amount of such increased cost, submitted to Borrower by
Lender, shall in the absence of manifest error, be conclusive.

     (B) If either (i) the introduction of or any change in or in the
interpretation of any law or regulation or (ii) compliance by Lender with any
guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by Lender and Lender determines
that the amount of such capital is increased by or based upon the existence of
Lender's commitment to lend hereunder and other commitments of this type, then,
upon demand by Lender, Borrower shall immediately pay to Lender, from time to
time as specified by Lender, additional amounts sufficient to compensate Lender
in the light of such circumstances, to the extent that Lender reasonably
determines such increase in capital to be allocable to the existence of Lender's
commitment to lend hereunder.  A certificate as to such amounts, submitted to
Borrower by Lender, shall, in the absence of manifest error, be conclusive and
binding for all purposes.

     (C) Notwithstanding anything contained herein to the contrary, in the event
that Lender makes demand on Borrower pursuant to Section 2.4(A) or (B) hereof
for the payment of any additional amounts as specified therein, Borrower may,
within ninety (90) days following the date of the delivery by Lender of the
certificate(s) described in Section 2.4(A) or (B) hereof, at Borrower's option,
terminate this Agreement upon ten (10) days prior written notice to Lender.
Upon the effective date of such termination, Borrower shall pay to Lender the
then outstanding principal, accrued interest and other charges owing under this
Agreement and any of the other Agreements, and the termination charges or
prepayment premium provided for in Section 3.3(C) of this Agreement shall not be
payable as a result of Borrower's termination pursuant to this Section 2.4(C).

SECTION 3.  INTEREST, FEES, TERM AND REPAYMENT

     3.1.  INTEREST AND CHARGES.

     (A) Subject to subsection (D) of this Section 3.1, interest shall accrue on
the principal amount of the Loans outstanding at the end of each day at a
fluctuating rate per annum equal to one and one-half percent (1.50%) above the
Base Rate.

     (B) After the date hereof, the Applicable Rate shall be increased or
decreased, as the case may be, by an amount equal to any increase or decrease in
the Base Rate, with such adjustments to be effective as of the opening of
business on the day that any such change in the Base Rate becomes effective.
The Base Rate in effect on the date hereof shall be the Base Rate effective as
of the opening of business on the date hereof, but if this Agreement is executed
on a day that is not a Business Day, the Base Rate in effect on the date hereof
shall be the Base Rate effective as of the opening of business on the last
Business Day immediately preceding the date hereof.  Interest on the unpaid
principal balance of the obligations shall be calculated on a daily basis
(computed on the actual number of days elapsed over a year of 360 days or, for
the purposes of determining interest at the Maximum Legal Rate, a year of 365 or
366 days, as applicable), commencing on the date hereof, and shall be payable
monthly, in arrears, on the first day of each month.

     (C) Subject to subsection (D) of this Section 3.1, upon and after the
occurrence of an Event of Default, and during the continuation thereof, the
principal amount of the obligations shall bear interest, calculated daily
(computed on the actual days elapsed over a year of 360 days), at a fluctuating
rate per annum equal to two percent (2%) above the Applicable Rate set forth in
Section 3.1(A) (the "Default Rate").

     (D) Notwithstanding the foregoing, (i) if at any time the amount of such
interest computed on the basis of the Applicable Rate would exceed the amount of
such interest computed upon the basis of the maximum rate of interest permitted
by applicable state or federal law in effect from time to time hereafter (the
"Maximum Legal Rate"), the interest payable under this Agreement shall be
computed upon the basis of the Maximum Legal Rate, but any subsequent reduction
in the Applicable Rate shall not reduce such interest thereafter payable
hereunder below the amount computed on the basis of the Maximum Legal Rate until
the aggregate amount of such interest accrued and payable under this Agreement
equals the total amount of interest which would have accrued if such interest
had been at all times computed solely on the basis of the Applicable Rate; and
(ii) unless preempted by federal law, the Applicable Rate from time to time in
effect hereunder may not exceed the "Indicated Rate Ceiling" from time to time
in effect

under Section (c) of Article 5069-1.04, Title 79, Revised Civil Statutes of
Texas, 1925, as amended.

     (E) No agreements, conditions, provisions or stipulations contained in this
Agreement or any other instrument, document or agreement between Borrower and
Lender or default of Borrower, or the exercise by Lender of the right to
accelerate the payment of the maturity of principal and interest, or to exercise
any option whatsoever contained in this Agreement or any other agreement between
Borrower and Lender, or the arising of any contingency whatsoever, shall entitle
Lender to collect, in any event, interest exceeding the Maximum Legal Rate and
in no event shall Borrower be obligated to pay interest exceeding such Maximum
Legal Rate and all agreements, conditions or stipulations, if any, which may in
any event or contingency whatsoever operate to bind, obligate or compel Borrower
to pay a rate of interest exceeding the Maximum Legal Rate, shall be without
binding force or effect, at law or in equity, to the extent only of the excess
of interest over such Maximum Legal Rate.  In the event any interest is charged
in excess of the Maximum Legal Rate ("Excess"), Borrower acknowledges and
stipulates that any such charge shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the principal then
unpaid hereunder; second, applied to reduce the obligations; and third, returned
to Borrower, it being the intention of the parties hereto not to enter at any
time into a usurious or otherwise illegal relationship.  Borrower recognizes
that, with fluctuations in the Applicable Rate and the Maximum Legal Rate, such
an unintentional result could inadvertently occur.  By the execution of this
Agreement, Borrower covenants that (i) the credit or return of any Excess shall
constitute the acceptance by Borrower of such Excess, and (ii) Borrower shall
not seek or pursue any other remedy, legal or equitable, against Lender, based
in whole or in part upon the charging or receiving of any interest in excess of
the maximum authorized by applicable law.  For the purpose of determining
whether or not any Excess has been contracted for, charged or received by
Lender, all interest at any time contracted for, charged or received by Lender
in connection with this Agreement, shall be amortized, prorated, allocated and
spread in equal parts during the entire term of this Agreement.

     (F) The provisions of Section 3.1(E) shall be deemed to be incorporated
into every document or communication relating to the obligations which sets
forth or prescribes any account, right or claim or alleged account, right or
claim of Lender with respect to Borrower (or any other obligor in respect of the
obligations), whether or not any provision of Section 3.1(E) is referred to
therein. All such documents and communications and all figures set forth therein
shall, for the sole purpose of computing the extent of the obligations and other
obligations of Borrower (or other obligor) asserted by Lender thereunder, be
automatically recomputed by Borrower or such obligor, and by any court
considering the same,


                                      -16-
<PAGE>
 
to give effect to the adjustments or credits required by Section 3.1(E).

     (G) If the applicable state or federal law is amended in the future to
allow a greater rate of interest to be charged under this Agreement or the other
Agreements than is presently allowed by applicable state or federal law, then
the limitation of interest hereunder shall be increased to the maximum rate of
interest allowed by applicable state or federal law as amended, which increase
shall be effective hereunder on the effective date of such amendment, and all
then accrued interest owing to Lender by reason thereof shall be payable UPON
DEMAND.

     (H) So long as no Default has occurred, in the event that Borrower achieves
the performance factors described below as of each of the calculation dates
specified below, then the Applicable Rate shall be reduced as follows:

     (i) Performance Factors to be Achieved as of October 31, 1991.  So long as
no Default has occurred, and so long as Borrower achieves the performance
factors set out below, upon the later of (i) receipt and review by Lender of
audited financial statements of Borrower provided pursuant to Section 9.1(J)
demonstrating compliance with the following performance factors, or (ii) receipt
by Lender of Borrower's Annual Business Plan for the twelve months ending
October 31, 1992, the Applicable Rate shall be reduced by 0.125%.  Such
reduction shall be made effective November 1, 1991 by (a) crediting the Loan
Account by the difference between the amount of interest paid by Borrower to
Lender since such effective date and the amount of interest which would have
been paid by Borrower to Lender since such effective date had the Applicable
Rate been so reduced, and (b) recalculating all accrued but unpaid interest, and
all interest to accrue with respect to future transactions, at the Applicable
Rate as so reduced.  The performance factors required to be achieved as of
October 31, 1991 in order to reduce the Applicable Rate are as follows:

     (A) The Average Daily Availability for the six months ending October 31,
1991 shall equal or exceed twenty-five percent (25%) of the Average Daily Loan
Balance for such period;

     (B) The Adjusted Net Earnings From Operations, plus taxes (to the extent
deducted therefrom), for the year ending October 31, 1991 shall be at least
$2,800,000; and

     (C) Borrower's Leverage Ratio as of October 31, 1991 shall not exceed 3.4
to 1.0.



                                      -17-
<PAGE>
 
Any rate reduction made pursuant to this Section 3.1(H)(i) shall remain in
effect only for so long as no Default has occurred and is continuing and
Borrower maintains the Leverage Ratio described in (C) above.

     (ii)     Performance Factors to be Achieved as of October 31, 1992. So long
as no Default has occurred, and so long as Borrower achieves the performance
factors set out below, upon the later of (i) receipt and review by Lender of
audited financial statements of Borrower provided pursuant to Section 9.1(J)
demonstrating compliance with the following performance factors, or (ii) receipt
by Lender of Borrower's Annual Business Plan for the twelve months ending
October 31, 1993, the Applicable Rate (as the same may or may not have been
reduced pursuant to Section 3.1(H)(i) above) shall be reduced by 0.25%. Such
reduction shall be made effective November 1, 1992 by (a) crediting the Loan
Account by the difference between the amount of interest paid by Borrower to
Lender since such effective date and the amount of interest which would have
been paid by Borrower to Lender since such effective date had the Applicable
Rate been so reduced, and (b) recalculating all accrued but unpaid interest, and
all interest to accrue with respect to future transactions, at the Applicable
Rate as so reduced. The performance factors required to be achieved as of
October 31, 1992 in order to reduce the Applicable Rate are as follows:

          (A) The Average Daily Availability for the months ending October 31,
     1992 shall equal or exceed twenty-five percent (25%) of the Average Daily
     Loan Balance for such period;

          (B) The Adjusted Net Earnings From operations, plus taxes (to the
     extent deducted therefrom), for the year ending October 31, 1992 shall be
     at least $2,500,000; and

          (C) Borrower's Leverage Ratio as of October 31, 1992 shall not exceed
     3.3 to 1.0.

Any rate reduction made pursuant to this Section 3.1(H)(ii) shall remain in
effect only for so long as no Default has occurred and is continuing and
Borrower maintains the Leverage Ratio described in (C) above.

     (iii)    Performance Factors to be Achieved by as of April 30, 1993. So
long as no Default has occurred, Borrower achieves the performance factors
described below, and the Applicable Rate has been and remains reduced pursuant
to each of Section 3.1(H)(i) and (ii) above, upon review and analysis by Lender
of the results of financial performance of Borrower for the period ending April
30, 1993 demonstrating compliance with the following performance factors, the
Applicable Rate


                                      -18-
<PAGE>
 
shall be further reduced by 0.125%.  Such reduction shall be made effective
May 1, 1993 by (a) crediting the Loan Account by the difference between the
amount of interest paid by Borrower to Lender since such effective date and the
amount of interest which would have been paid by Borrower to Lender since such
effective date had the Applicable Rate been so reduced, and (b) recalculating
all accrued but unpaid interest, and all interest to accrue with respect to
future transactions, at the Applicable Rate as so reduced.  The performance
factors required to be achieved as of April 30, 1993 in order to reduce the
Applicable Rate are as follows:

          (A) The Average Daily Availability for the six months ending April 30,
     1993 shall equal or exceed twenty-five percent (25%) of the Average Daily
     Loan Balance for such period;

          (B) The Adjusted Net Earnings From operations, plus taxes (to the
     extent deducted therefrom), for the six months ending April 30, 1993 shall
     be at least $1,250,000; and

          (C) Borrower's Leverage Ratio as of April 30, 1993 shall not exceed
     3.2 to 1.0.

Any rate reduction made pursuant to this Section 3.1(H)(iii) shall remain in
effect only for so long as no Default has occurred and is continuing and
Borrower maintains the Leverage Ratio described in (C) above.  In addition, in
the event that following any reduction in the Applicable Rate pursuant to this
Section 3.1(H)(iii), Borrower's annual audited financial statements delivered to
Lender pursuant to this Agreement reflect that Borrower was not entitled to such
reduction (notwithstanding that Borrower's unaudited financial statements
reflected that Borrower was entitled to such reduction), then Borrower shall (i)
immediately pay to Lender the difference between (a) the amount of interest paid
by Borrower to Lender since the date of the reduction of the Applicable Rate,
and (b) the amount of interest which would have been paid by Borrower to Lender
if the Applicable Rate had not been reduced, and (ii) the Applicable Rate shall
be immediately increased by 0.125% per annum with respect to all future
transactions.

     3.2. FEES.

          (A) Closing Fee. Borrower shall pay to Lender a closing fee of
$125,000, which shall be deemed fully earned and nonrefundable at the closing of
the transactions contemplated hereby and shall be paid concurrently with the
initial Loan hereunder. Such fee shall compensate Lender for the costs
associated with the origination, structuring, processing, approving and closing
of the transactions contemplated by this Agreement, including, but not limited
to, administrative, out-of-pocket,

                                      -19-
<PAGE>
 
general overhead and lost opportunity costs, but not including any expenses for
which Borrower has agreed to reimburse Lender pursuant to any other provision of
this Agreement (for example, reasonable attorney's fees incurred by Lender) or
any other Agreement.

          (B) Audit Fee. Borrower agrees to pay to Lender an audit fee payable
on a semiannual basis beginning on November 1, 1991 and continuing regularly
thereafter on the first day of each six-month period during the term of this
Agreement and upon termination hereof. The audit fee payable at any date shall
equal $2,000 plus all out of pocket costs and expenses incurred by Lender during
the preceding six month period in connection with administering the Loans,
provided the audit fee paid in any twelve-month period shall not exceed
$5,000.00 and shall not at any time be equal to or in excess of the amount which
would cause the interest on the obligations to exceed the Maximum Legal Rate.
This fee shall compensate Lender for certain aspects of administering the Loans,
including, without limitation, certain internal audits, appraisals and
collateral monitoring functions deemed necessary or appropriate by Lender, but
shall not include any expenses for which Borrower has agreed to reimburse Lender
pursuant to any other provision of this Agreement or any Other Agreement.

          (C) Unused Facility Fee. Borrower agrees to pay to Lender a quarterly
unused facility fee, equal to one-half percent (0.50%) per annum of the average
daily unused portion of the Commitment, payable quarterly in arrears, beginning
August 1, 1991 and continuing regularly thereafter during the term of this
Agreement and upon the termination hereof.

     3.3. TERM OF AGREEMENT; TERMINATION.

          (A) The provisions of this Agreement shall be in effect for a period
of three (3) years from the date hereof, through and including May 3, 1994 (the
"Original Term"), unless terminated as provided in Section 3.3(B) hereof, or
extended pursuant to this Section 3.3(A). So long as no Default has occurred,
the original Term shall be automatically extended by one (1) year unless
Borrower has notified Lender, or Lender has notified Borrower, on or before
January 3, 1994, that it does not desire this Agreement to be extended pursuant
to this Section 3.3(A).

          (B) Upon at least ninety (9O) days prior written notice to Lender,
Borrower may, at its option, terminate this Agreement; provided, however, no
such termination shall be effective until Borrower has paid all of the
obligations in immediately available funds, together with the termination charge
or prepayment premium provided for in Section 3.3(C) hereof, if any. It is
understood that Borrower may elect to terminate this Agreement in its entirety
only; no section or lending facility may be terminated singly. Lender may
terminate this Agreement without notice upon or after the occurrence of an Event
of Default.

                                      -20-
<PAGE>
 
          (C) At the effective date of such termination by Borrower, Borrower
shall pay to Lender (in addition to the then outstanding principal, accrued
interest and other charges, fees and expenses owing under this Agreement and any
of the other Agreements), as liquidated damages for the loss of the bargain and
not as a penalty, an amount equal to the applicable percentage set forth below
of the highest of the Average Daily Loan Balances outstanding for any month
during the applicable term set forth below during which such termination occurs:

     Applicable Term              Applicable Percentage
     ---------------              ---------------------

     The date hereof through                 3%
       May 2, 1992

     May 3, 1992, through                    2%
       May 2, 1993

     May 3, 1993, through                    1%
       May 2, 1994

     Thereafter                              0%

If termination occurs on the last day of the original Term, Borrower shall not
be obligated to pay Lender any liquidated damages.

          (D) All of the obligations shall be forthwith due and payable upon any
termination of this Agreement.  Except as otherwise expressly provided for in
this Agreement or any of the other Agreements, no termination or cancellation
(regardless of cause or procedure) of this Agreement or any of the other
Agreements shall in any way affect or impair the powers, obligations, duties,
rights, and liabilities of Borrower or Lender in any way relating to (i) any
transaction or event occurring prior to such termination or cancellation or (ii)
any of the undertakings, agreements, covenants, warranties or representations of
Borrower contained in this Agreement or any of the other Agreements. All such
undertakings, agreements, covenants, warranties and representations shall
survive such termination or cancellation and Lender shall retain its Liens in
the Collateral, and all of its rights and remedies under this Agreement and the
other Agreements notwithstanding such termination or cancellation, until
Borrower has paid the obligations to Lender, in full, in immediately available
funds.

     3.4.  PAYMENTS.  Except where evidenced by notes or other instruments
issued or made by Borrower to Lender specifically containing payment provisions
which are in conflict with this Section 3.4 (in which event the conflicting
provisions of said notes or other instruments shall govern and control), that
portion of the obligations consisting of:

                                      -21-
<PAGE>
 
          (A) Principal, payable on account of Loans made by Lender to Borrower,
shall be payable by Borrower to Lender immediately upon the earliest of (i) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the Obligations, or (ii) termination of
this Agreement pursuant to Section 3.3 hereof; provided, however, that if the
principal balance of Loans outstanding at any time shall exceed the Borrowing
Base at such time, Borrower shall, ON DEMAND, repay the Loans in an amount
sufficient to reduce the aggregate unpaid principal amount of such Loans by an
amount equal to such excess;

          (B) Interest accrued on the obligations shall be due on the earliest
of (i) the first day of each month (for the immediately preceding month),
computed through the last calendar day of the preceding month, (ii) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the obligations or (iii) termination of
this Agreement pursuant to Section 3.3 hereof; provided, however, that Borrower
hereby irrevocably authorizes Lender, in Lender's sole discretion, to advance to
Borrower, and to charge to the Loan Account hereunder as a Loan, a sum
sufficient each month to pay all interest accrued on the obligations during the
immediately preceding month; and

          (C) The remainder of the obligations requiring the payment of money,
if any, shall be payable by Borrower to Lender as and when provided in this
Agreement or the other Agreements.

     3.5.  APPLICATION OF PAYMENTS AND COLLECTIONS.  Borrower irrevocably waives
the right to direct the application of any and all payments and collections at
any time or times hereafter received by Lender from or on behalf of Borrower,
and Borrower hereby irrevocably agrees that Lender shall have the continuing
exclusive right to apply and reapply any and all such payments and collections
received at any time or times hereafter by Lender or its agent against the
obligations, in such manner as Lender may deem advisable, notwithstanding any
entry by Lender upon any of its books and records.  If as the result of
collections of Accounts as authorized by Section 5.2 hereof, a credit balance
exists in the Loan Account, such credit balance shall not accrue interest in
favor of Borrower, but shall be available to Borrower at any time or times for
so long as no Default or Event of Default exists.

     3.6.  STATEMENTS OF ACCOUNT.  Lender will account to Borrower monthly with
a statement of Loans, charges and payments made pursuant to this Agreement, and
such account rendered by Lender shall be deemed final, binding and conclusive
upon Borrower, unless Lender is notified by Borrower in writing to the contrary
within thirty (30) days of the date each account was rendered.  Such notice
shall only be deemed an objection to those items specifically objected to
therein.

                                      -22-

SECTION 4.  COLLATERAL: GENERAL TERMS

     4.1.   SECURITY INTEREST IN COLLATERAL.  To secure the prompt payment and
performance to Lender of the Obligations, Borrower hereby grants to Lender a
continuing security interest in and Lien upon all the Property and interests in
Property of Borrower, whether now owned or existing or hereafter created,
acquired or arising and wheresoever located, including, without limitation, the
following Property and interests in Property:

            (A)  Accounts;

            (B)  Inventory;

            (C)  Equipment;

            (D)  General Intangibles;

            (E) All monies and other Property of any kind, now or at any time or
times hereafter, in the possession or under the control of Lender or a bailee of
Lender;

            (F) All accessions to, substitutions for and all replacements,
products and cash and non-cash proceeds of (A), (B), (C), (D) and (E) above,
including, without limitation, proceeds of and unearned premiums with respect to
insurance policies insuring any of the Collateral; and

            (G) All books and records (including, without limitation, customer
lists, credit files, computer programs, print-outs, and other computer materials
and records) of Borrower pertaining to any of (A), (B), (C), (D), (E) or (F)
above.

     4.2.   FINANCING STATEMENTS; WARRANTIES REGARDING PRIORITY OF THE LIENS OF
LENDER IN THE COLLATERAL.

            (A) Borrower agrees to execute the financing statements provided for
by the Code and by Chapter 9, together with any and all other instruments,
assignments or documents, and shall take such other action as may be required to
create, perfect or to continue the perfection of Lender's security interest in
the Collateral. Unless prohibited by applicable law, Borrower hereby authorizes
Lender to execute and file any such financing statement on Borrower's behalf.
The parties agree that a carbon, photographic or other reproduction of this
Agreement shall be sufficient as a financing statement and may be filed in any
appropriate office in lieu thereof.

          (B) Borrower is the owner of full legal and equitable title to the
Collateral, free and clear of any Liens, except Permitted Liens, and, other than
in connection with Permitted Liens, no financing statement covering the
Collateral or any part

                                      -23-
<PAGE>
 
or proceeds thereof is on file in any public office, and the execution by
Borrower of this Agreement and the other Agreements to which it is a party and
the filing of the relevant financing statements in the appropriate jurisdictions
will create in favor of the Lender a valid, perfected first Lien against the
Collateral, subject to the Permitted Liens.

     4.3.  LOCATION OF COLLATERAL.  All Collateral, other than Inventory in
transit and motor vehicles, will at all times be kept by Borrower at one or more
of the business locations set forth in Exhibit "A" and shall not, without the
prior written approval of Lender, be moved therefrom except, prior to an Event
of Default and Lender's acceleration of the maturity of the obligations in
consequence thereof, for sales of Inventory in the ordinary course of business,
dispositions of Equipment that are authorized by Section 7.2 hereof and
Inventory and Equipment in transit from one business location to another.

     4.4.  INSURANCE OF COLLATERAL.  Borrower agrees to maintain and pay for
insurance upon such of the Tangible Collateral as shall be required by Lender,
wherever located, in storage or in transit in vehicles, including goods
evidenced by documents, covering casualty, hazard, public liability and such
other risks and in such amounts and with such insurance companies as shall be
reasonably satisfactory to Lender to insure Lender's interest in the Collateral.
Borrower shall deliver certificates for such policies to Lender with
satisfactory lender's loss payable endorsements naming Lender loss payee.  Each
policy of insurance or endorsement shall contain a clause requiring the insurer
to give not less than thirty (30) days prior written notice to Lender in the
event of cancellation of the policy for any reason whatsoever and a clause, if
such a clause is permitted in policies issued in the State of Texas, that the
interest of Lender shall not be impaired or invalidated by any act or neglect of
Borrower or owner of the Property nor by the occupation of the premises for
purposes more hazardous than are permitted by said policy.  If Borrower fails to
provide and pay for such insurance, Lender may, at Borrower's expense, procure
the same, but shall not be required to do so. Borrower agrees upon request by
Lender, to deliver to Lender, promptly as rendered, true copies of all reports
made in any reporting forms to insurance companies.

     4.5.  PROTECTION OF COLLATERAL.  Borrower shall pay and discharge when due
all claims to and levies and charges upon any of the Collateral. Lender may, at
any time or times hereafter, in its sole discretion, without waiving or
releasing any obligations, liability or duty of Borrower under this Agreement or
the other Agreements, or any Event of Default, pay when due, acquire or accept
an assignment of any Lien or claim asserted by any Person against any of the
Collateral; provided, however, as long as no Event of Default has occurred,
Lender shall notify Borrower if any single such payment will be in excess of
$5,000.  All sums paid by

                                      -24-
<PAGE>
 
Lender in respect thereof and all costs, fees and expenses, including, without
limitation, attorney's fees and court costs, which are incurred by Lender on
account thereof, shall be payable UPON DEMAND by Borrower to Lender, together
with interest accruing at the Default Rate from the date of demand until paid
and shall be secured by the Collateral.  Lender shall not be liable or
responsible in any way for the safekeeping of any of the Collateral or for any
loss or damage thereto or for any diminution in the value thereof, or for any
act or default of any warehouseman, carrier, forwarding agency, or other Person
whomsoever, but the same shall be at Borrower's sole risk.

SECTION 5.  PROVISIONS RELATING TO ACCOUNTS

     5.1.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  With respect to all
Accounts, Borrower represents and warrants to Lender that Lender may rely, in
determining which Accounts are Eligible Accounts, on all statements and
representations made by Borrower with respect to any Account or Accounts, and,
unless otherwise indicated in writing to Lender, that with respect to each
Account:  it is genuine and in all respects what it purports to be, and it is
not evidenced by a judgment; it arises out of a completed, bona fide sale and
delivery of goods or rendition of services by Borrower in the ordinary course of
its business and in accordance with the terms and conditions of all purchase
orders, contracts or other documents relating thereto; it is for a liquidated
amount maturing as stated in the duplicate invoice covering such sale or
rendition of services; such Account, and Lender's security interest therein, is
not, and, to the best of Borrower's knowledge, will not be in the future,
subject to any offset, Lien, deduction, defense, dispute, counterclaim or any
other adverse condition, except for disputes resulting in returned goods where
the amount in controversy is deemed by Lender to be immaterial, and, to the best
of Borrower's knowledge, each such Account is absolutely owing to Borrower and
is not contingent in any respect or for any reason; Borrower has made no
agreement with any Account Debtor thereunder for any deduction therefrom, except
discounts or allowances which are granted by Borrower in the ordinary course of
its business for prompt payment; to the best of Borrower's knowledge, there are
no facts, events or occurrences which in any way impair the validity or
enforceability thereof or tend to reduce the amount payable thereunder from the
face amount of the invoice and statements delivered to Lender with respect
thereto; to the best of Borrower's knowledge, the Account Debtor thereunder (i)
had the capacity to contract at the time any contract or other document giving
rise to the Account was executed and (ii) such Account Debtor is Solvent; and
Borrower has no knowledge of any fact or circumstance which would impair the
validity or collectibility of the Account.

     5.2.   COLLECTION OF ACCOUNTS.  To expedite collection, Borrower shall
endeavor in the first instance to make collection of their Accounts for Lender.
All remittances received by Borrower on

                                      -25-
<PAGE>
 
account of Accounts shall be held as Lender's property by Borrower as trustee of
an express trust for Lender's benefit and Borrower shall deposit same in the
Dominion Account.  Lender retains the right, upon and after the occurrence of an
Event of Default, to notify Account Debtors that Accounts have been assigned to
Lender and to collect Accounts directly in its own name and to charge the
collection costs and expenses, including attorneys' fees, to Borrower.  Lender
has no duty to protect, insure, collect or realize upon the Accounts or preserve
rights in them.  For the purpose of computing interest hereunder, all items of
payment received by Lender shall be deemed applied by Lender on account of the
obligations (subject to final payment of such items) on the first Business Day
after Lender's withdrawal of such payment from the Dominion Account in
immediately available funds.  Whenever reasonably practicable, Lender shall
withdraw all funds contained in the Dominion Account on a daily basis, for
application of such funds to the payment of the obligations as provided herein.
Borrower shall deposit all proceeds of the Collateral or cause the same to be
deposited in kind in the Dominion Account pursuant to an arrangement with such
banks as may be selected by Borrower and be acceptable to Lender.  Borrower
shall deposit all payments or other remittances received by Borrower in their
operating accounts to the Dominion Account.  After the occurrence of an Event of
Default Lender may, and Borrower shall at Lender's request, notify Account
Debtors and all other parties obligated on the Collateral to make payments
directly to the Dominion Account.  All funds deposited in the Dominion Account
shall immediately become the Property of Lender, and Borrower shall obtain the
agreement by such banks to waive any offset rights against the funds so
deposited.  Lender assumes no responsibility for such account arrangement,
including, without limitation, any claim of accord and satisfaction or release
with respect to deposits accepted by any bank thereunder.

     5.3.   ADMINISTRATION OF ACCOUNTS.  Upon the granting of any discounts,
allowances or credits by Borrower that are not shown on the face of the invoice
for the Account involved, Borrower shall promptly report such discounts,
allowances or credits, as the case may be, to Lender and in no event later than
the time of its submission to Lender of the next Schedule of Accounts as
provided in Section 5.4.  If an Account includes a charge for any tax payable to
any governmental taxing authority, Lender is authorized, in its sole discretion,
to pay the amount thereof to the proper taxing authority for the account of
Borrower and to charge Borrower's Loan Account hereunder therefor.  Whether or
not a Default or an Event of Default has occurred, Lender shall have the right,
at any time or times hereafter, in the name of Lender, any designee of Lender or
Borrower, to verify the validity, amount or any other matter relating to any
Accounts, such verification to be in a format reasonably satisfactory to Lender
and Borrower or, if Lender decides, in its sole discretion, to use a different
format or method, such format or method regarding which Borrower shall have been
notified; provided, however, that after the occurrence of

                                      -26-
<PAGE>
 
an Event of Default, Lender shall have the right to determine, in its sole
discretion, the format and method for such verification without the obligation
of giving notice to the Borrower of the format and method decided upon by
Lender.  Borrower shall cooperate fully with Lender in an effort to facilitate
and promptly conclude any such verification process.

     5.4.   ASSIGNMENTS, RECORDS AND SCHEDULES OF ACCOUNTS.  Borrower shall keep
accurate and complete records of its Accounts and all payments and collections
thereon.  On or before the 20th day of each month from and after the date
hereof, Borrower shall deliver to Lender, in form acceptable to Lender, a
detailed aged trial balance of all Accounts existing as of the last day of the
preceding month, specifying the names, addresses, face value, dates of invoices
and due dates for each Account Debtor obligated on an Account so listed
("Schedule of Accounts"), along with, if requested by Lender, copies of proof of
delivery and the original copy of all documents, including, without limitation,
repayment histories and present status reports relating to the Accounts so
scheduled and such other matters and information relating to the status of then
existing Accounts as Lender shall reasonably request, and also with, if
requested by Lender, formal written assignments by Borrower to Lender of all of
Borrower's Accounts, together with copies of invoices or invoice registers
related thereto.  If any amounts due and owing in excess of $10,000 are in
dispute between Borrower and any Account Debtor, Borrower shall provide Lender
with written notice thereof at the time of submission of the next Schedule of
Accounts, explaining in detail the reason for the dispute, all claims related
thereto, and the amount in controversy.  In addition to and not in limitation of
the other provisions of this Section 5.4, if at any time a Default occurs,
Lender shall thereafter have the right to require that Borrower deliver to
Lender such other reports, information and materials regarding the Accounts as
shall be specified by Lender.

SECTION 6.  PROVISIONS RELATING TO INVENTORY

     6.1.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  With respect to
Inventory, Borrower represents and warrants to Lender that Lender may rely, in
determining which items of Inventory constitute Eligible Inventory, on all
statements and representations made by Borrower with respect to any Inventory
and, unless otherwise indicated in writing to Lender, that:  all Inventory is
presently and will continue to be located at Borrower's places of business
listed on Exhibit "A" and will not be removed therefrom, except as authorized by
Section 4.3 of this Agreement; no Inventory is now, nor shall any Inventory at
any time or times hereafter be, stored with a bailee, warehouseman or similar
party unless (i) Lender shall have granted its prior written consent thereto,
(ii) such bailee, warehousemen or similar party shall have delivered to Lender a
warehousemen's letter in the form requested by Lender, and (iii) all original
warehouse receipts or other documents relating

                                      -27-

will be sold by consignment by any Person without Lender's prior written
consent, except as otherwise disclosed on Exhibit "A".

     6.2.   INVENTORY REPORTS. On or before the 20th day of each month from and
after the date hereof, Borrower agrees to furnish Lender with Inventory reports.
Such reports shall be in form and detail satisfactory to Lender.  Borrower shall
conduct such physical inventory tests as are acceptable to the independent
certified public accountants of Borrower who are preparing the financial
statements referred to in Section 9.1(J) and Borrower shall provide to Lender,
upon request by Lender, an annual report regarding their physical inventory
based upon such testing procedures, as well as copies of any other inventory
tests conducted by or on behalf of Borrower, together with such supporting
information as Lender shall, in its discretion, request.  In addition to and not
in limitation of the other provisions of this Section 6.2, if at any time a
Default occurs, Lender shall thereafter have the right to require that Borrower
deliver to Lender such other reports, information and materials regarding the
Inventory as shall be specified by Lender.

     6.3.   RETURNS OF INVENTORY.  If at any time or times hereafter any Account
Debtor returns any Inventory with a cost or market value in excess of $10,000 to
Borrower, Borrower shall notify Lender of the same immediately, specifying the
reason for such return and the location and condition of the returned Inventory.

SECTION 7.  PROVISIONS RELATING TO EQUIPMENT

     7.1.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  With respect to the
Equipment, Borrower represents, warrants and covenants to and with Lender that
Borrower has good and marketable title to the Equipment, that the Equipment is
in good operating condition and repair, and all necessary replacements of and
repairs thereto shall be made so that the value and operating efficiency of the
Equipment shall be maintained and preserved, reasonable wear and tear excepted.
Borrower will not permit any of the Equipment to become affixed to any real
Property leased to Borrower, so that an interest arises therein under the real
estate laws of the applicable jurisdiction, unless the landlord of such real
Property has executed a landlord waiver in favor of Lender, and Borrower will
not permit any of the Equipment to become an accession to any personal Property,
other than Equipment subject to first priority Liens in favor of Lender, subject
only to Permitted Liens.  Immediately on request therefor by Lender, Borrower
shall deliver to Lender any and all evidence of ownership, if any, of any of the
Equipment (including, without limitation, certificates of title and applications
for title).  Borrower shall maintain accurate records itemizing and describing
the kind, type, quality, quantity and value of its Equipment and all
dispositions made in accordance with

                                      -28-
<PAGE>
 
Section 7.2 hereof, and shall furnish Lender with a current schedule containing
the foregoing information on at least an annual basis and more often if
requested by Lender.

     7.2.   DISPOSITIONS OF EQUIPMENT.  Borrower will not sell, lease or
otherwise dispose of or transfer any of the Equipment or any part thereof
without the prior written consent of Lender; provided, however, that the
foregoing restriction on the sale, lease, disposition or other transfer of any
Equipment shall not apply, for so long as no Default or Event of Default exists,
to (i) dispositions of Equipment which, in the aggregate during any consecutive
twelve-month period, has a fair market value or book value, whichever is less,
of $100,000 or less, provided that all proceeds thereof are turned over to
Lender to be applied by Lender in accordance with Section 3.5 hereof, or (ii)
replacement of Equipment that is substantially worn, damaged or obsolete with
Equipment of like kind, function and value, provided that the replacement
Equipment shall be acquired prior to or concurrently with any disposition of the
Equipment that is to be replaced, the replacement Equipment shall be free and
clear of Liens, other than Permitted Liens, Borrower shall give Lender at least
five (5) days prior written notice of such disposition, and Borrower shall turn
over to Lender all proceeds realized from any such disposition to be applied by
Lender in accordance with Section 3.5 hereof.

Borrower's Properties, except for Permitted Liens.

            (B) File all federal, state and local tax returns and other reports

Borrower or any other Person on behalf of Borrower, by Lender or any
Participating Lender, proceeds of Loans made by Lender to Borrower pursuant to
this Agreement, and (ii) the depositing for collection, by Lender

shall cause to be prepared and furnished to Lender a certificate from the Chief
Financial officer of Borrower certifying to Lender that, to the best of his
knowledge, Borrower has kept, observed, performed and fulfilled each and every

Borrower, a certificate (the "Compliance


                                      -34-
<PAGE>
 
Certificate"), which shall state the Borrower's compliance or non-compliance
with the financial covenants contained in Section 9.3 of this Agreement, the
Compliance Certificate to be substantially in the form of Exhibit "H" to this
Agreement, the Compliance Certificate for each of the first three fiscal
quarters in each fiscal year of the Borrower to be furnished to Lender on or

except in the ordinary course of and pursuant to the reasonable requirements of
Borrower's business and upon fair and reasonable terms which are fully disclosed

comparable arm's length transaction with a Person not an Affiliate or
stockholder of Borrower.

            (D) Guarantee, assume, endorse or otherwise, in any way, become
directly or contingently liable with respect to the Indebtedness of any Person,
except by endorsement of instruments or items of payment for deposit or
collection.

            (E) Create or suffer to exist any Lien upon any of its Property,
income or profits, whether now owned or hereafter acquired, except: (i) Liens at

imposed pursuant to any of the provisions of ERISA) not yet due or being
contested as permitted by Section 9.1(A) hereof, but only if in Lender's
judgment, such Lien does not affect adversely Lender's rights or the priority of
Lender's Lien in the Collateral; (iii) Liens securing the claims or demands of
materialmen, mechanics, carriers, warehousemen, and other like Persons for
labor, materials or


                                      -35-

the Liens in favor of Lender; (iv) deposits made in the ordinary course of
business in connection with worker's compensation, unemployment insurance,
social security and other like laws; (v) attachment, judgment and other similar
non-tax Liens arising in connection with court proceedings, but only if and for
so long as the execution or other enforcement of such Liens is and continues to
be effectively stayed and bonded on appeal in a manner satisfactory to Lender
for the full amount thereof, the validity and amount of the claims secured
thereby are being actively contested in good faith and by appropriate lawful
proceedings and such Liens do not, in the aggregate, materially detract from the
value of the Property of Borrower or materially impair the use thereof in the
operation of Borrower's business; (vi) Purchase Money Liens securing
indebtedness incurred for the payment of Capital Expenditures permitted by this
Agreement; (vii) reservations, exceptions, easements, rights of way, and other
similar encumbrances affecting real Property, provided that, in Lender's sole
judgment, they do not in the aggregate materially detract from the value of said
Properties or materially interfere with their use in the ordinary conduct of
Borrower's business and, if said real Property constitutes Collateral, Lender
has consented thereto; (viii) Liens permitted pursuant to the provisions of any
other Agreement; (ix) Landlord or warehouseman liens with respect to any
premises leased by Borrower or upon which Borrower's goods are stored, as long
as Lender pursuant to Section 10.1(C) of this Agreement has deducted as a
reserve from the amount of the Borrowing Base an amount equal to the total
rental for the remaining lease term for such premises; (x) Liens specified on
Exhibit "D" attached hereto and (xi) such other Liens as Lender may hereafter
approve in writing.

            (F) Make Distributions during any fiscal year, in excess of the
aggregate amount of $15O,OOO, other than (i) compensation of officers and
directors permitted pursuant to Section 9.2(M), and (ii) redemption of the
currently outstanding series B preferred stock of Borrower on October 31, 1993
pursuant to the terms of that certain Amended Financial Agreement dated October
24, l99O between otter, Inc. and Borrower (The "Financial Agreement"), provided,
immediately after giving effect to such redemption, the Borrowing Base as of
such date, less the aggregate amount of Loans outstanding as of such date,
equals or exceeds twenty-five percent (25%) of the Average Daily Loan Balance
for the six months preceding such date. Borrower shall not modify the terms of
the Financial Agreement.

            (G) Hereafter create any Subsidiary or divest itself of any material
assets by transferring them to any Subsidiary to whose existence Lender has
consented.

            (H) Make Capital Expenditures or payments on account of Capital
Leases which exceed in the aggregate (i) for the period from May 1, 1991 to

occurring.

            (I) Transfer its principal place of business or chief executive
office, or open manufacturing plants, or maintain or transfer Collateral or
records with respect to Accounts or Inventory, to or at any locations other than

parts of laws relative to the appraisement of the property seized and sold,
under executory process or other legal process, and consenting that the
Collateral be sold without appraisement, either in its entirety or in lots or
parcels, as Lender may determine, to the highest bidder for cash or on such
other terms as the plaintiff in such proceeding may direct. Furthermore, upon
the occurrence of an Event of Default, if Lender employs an attorney to enforce
Lender's rights in Louisiana against Borrower or any other Person which may be
obligated to Lender under this Agreement or any of the other Agreements,
Borrower agrees to pay Lender's reasonable attorney's fees in an amount equal to
5% of the unpaid obligations then due and owing.

     Borrower hereby waives (a) the benefit of appraisement provided for in
Articles 2332, 2336, 2723, and 2724 of the Louisiana Code of Civil Procedure and
all other laws conferring the same; (b) the demand and three (3) days notice of

due or sued for or claimed or sought to be protected, preserved or enforced in
the proceeding for the recognition or enforcement of this Loan and Security
Agreement, and shall be secured by the security interest herein granted.

control; and

this indemnity shall extend to any claims asserted against Lender by any Person
under any Environmental Laws or similar laws by reason of Borrower's or any
other Person's failure to comply with laws applicable to solid or hazardous
waste materials or other toxic substances. The obligation of Borrower under this
Section 12.2 shall survive the payment in full of the obligations and the
termination of this Agreement.

subsequent to the date hereof, regardless of whether or not an Event of Default

income of Lender) shall be payable on account of the execution or delivery of
this Agreement, or the execution, delivery, issuance or recording of any of the
other Agreements, or the creation of any of the obligations hereunder, by reason
of any existing or hereafter enacted federal or state statute, Borrower will pay
all such taxes, including, but not limited to, any interest and penalties
thereon, and will indemnify and hold Lender harmless from and against liability
in connection therewith. Borrower hereby irrevocably authorizes Lender to enter
any and all expenses or other amounts owing to Lender by Borrower pursuant to
this Section 12.4 as debits in the Loan Account.

     12.5.  INDULGENCES NOT WAIVERS. Lender's failure, at any time or times
hereafter, to require strict performance by Borrower of any provision of this
Agreement shall not waive, affect or diminish any right of Lender thereafter to
demand strict compliance and performance therewith. Any suspension or waiver by
Lender of an Event of Default under this Agreement or any of the other
Agreements shall not suspend, waive or affect any other Event of Default under
this Agreement or any of the other Agreements,

     2.   THE LOANS. Section 2.1 of the Agreement is hereby deleted, and in
place thereof shall be the following:

          "2.1.  THE LOANS AND LC GUARANTIES.

                 (A) Provided that no Default or Event of Default has occurred,
                 Lender will make Revolving Credit Loans to Borrower from time
                 to time, in amounts as requested by Borrower, up to a maximum


                                      -4-
<PAGE>
 
          principal amount at any time outstanding equal to the Borrowing Base
          at such time. It is expressly understood and agreed that Lender may
          use the Borrowing Base as a maximum ceiling on Revolving Credit Loans
          outstanding to Borrower at any time. If the unpaid balance of the
          Revolving Credit Loans should exceed the Borrowing Base or any other
          limitation set forth in this Agreement, such Revolving Credit Loans
          shall nevertheless constitute obligations that are secured by the
          Collateral and entitled to all benefits thereof. Insofar as Borrower
          may request and Lender may be willing in its discretion to make
          Revolving Credit Loans to Borrower at a time when the unpaid balance
          of Revolving Credit Loans exceeds, or would exceed with the making of
          any such Revolving Credit Loan, the Borrowing Base (any such Revolving
          Credit Loan or Loans being herein referred to individually as an
          "Overadvance" and collectively as "Overadvances", Lender shall enter
          such Overadvances as debits in the Loan Account. All Overadvances
          shall be repaid ON DEMAND. In consideration of Lender making any
          Overadvance to Borrower, Borrower agrees to pay to Lender,
          contemporaneously with the making of such overadvance, an amount equal
          to one percent (1%) of the Overadvance, provided that the payment of
          such amount does not cause the interest ON the obligations to exceed
          the Maximum Legal Rate. The Revolving Credit Loans shall be used
          solely (i) for the satisfaction of existing Indebtedness of Borrower
          to F&M Bank and Trust Company of Tulsa, oklahoma, (ii) for the
          satisfaction of certain trade payables and other unsecured
          indebtedness owed to trade creditors of Borrower, (iii) for Borrower's
          general operating capital needs to the extent not inconsistent with
          the provisions of this Agreement, and (iv) for the payment of any of
          the fees specified in Section 3.2 of this Agreement and, to the extent
          approved by Lender, to the payment of any costs associated with the
          closing of the transactions contemplated by this Agreement.

                 (B) Subject to the terms and conditions of this Agreement,
          Lender agrees to make a term loan to Borrower in the aggregate
          principal amount of up to $500,000, which shall bear interest and be
          repayable in accordance with the terms of the Term Note and shall be
          secured by the Collateral. The Term Loan may be advanced in two
          advances in the amounts of up to $385,000 and $115,000, respectively.
          The proceeds of the first advance shall be used by Borrower solely for
          the purpose of


                                      -5-
<PAGE>
 
          purchasing the Real Property other than the Real Property located in
          Conroe, Texas, and the proceeds of the second advance shall be used
          solely for the purpose of purchasing real Property.

                 (C) Provided that no Default or Event of Default has
          occurred, Borrower may request from time to time that Lender provide
          LC Guaranties to support Letters of Credit to be issued for the
          account of Borrower, not to exceed the face amount of $500,000
          outstanding at any time. Borrower acknowledges that execution of any
          LC Guaranty requested by Borrower shall be in the sole discretion of
          Lender, and that any Letter of Credit will be subject to the terms,
          conditions and requirements of the Person issuing such Letter of
          Credit. If at any time Lender is called upon under an LC Guaranty to
          reimburse to the issuer of any Letter of Credit any draft drawn upon
          such Letter of Credit, Borrower shall be deemed to have borrowed, as
          of the date of such reimbursement, a Revolving Credit Loan in the
          amount of such reimbursement."

     3.   INTEREST AND CHARGES.

          (a) Section 3.1(A) of the Agreement is hereby deleted, and in place

          "Annual Term Rate"), or (ii) the Maximum Legal Rate. The principal
          amount of the Revolving Credit Loans outstanding from day-to-day shall
          bear interest, calculated daily at a fluctuating rate per annum equal
          to the lesser of (i) 2.0% (or such lesser percentage as may be
          provided by subsection (H) hereof) above the Base Rate (the "Annual
          Revolving Rate"), or (ii) the Maximum Legal Rate."

          (b) All references in Section 3.1(H) of the Agreement to the
     "Applicable Rate" are hereby amended to be references to the "Annual
     Revolving Rate."

     4.   FEES. The following Sections 3.2(D) and 3.2(E) are hereby added to the
Agreement:

                    "(D)  Term Loan Closing Fee.  On or before the first Term
          Loan Closing Date, Borrower shall pay to Lender a Term Loan closing
          fee of $5,000, which shall be


                                      -6-
<PAGE>
 
     deemed fully earned and nonrefundable at the first Term Loan Closing Date
     and shall be paid concurrently with the first advance under the Term Loan.
     Such fee shall compensate Lender for the costs associated with the
     origination, structuring, processing, approving and closing of the Term
     Loan, including, but not limited to, administrative, out-of-pocket, general
     overhead and lost opportunity costs, but not including any expenses for
     which Borrower has agreed to reimburse Lender pursuant to any other
     provision of this Agreement (for example, reasonable attorney's fees
     incurred by Lender) or any other Agreement."

               "(E)  LC Guaranty Fee. Borrower agrees to pay to Lender a monthly
     LC Guaranty Fee, equal to 2.5% per annum of the face amount of the Letters
     of Credit (if any) outstanding during such month for which Lender has
     issued LC Guaranties. The LC Guaranty Fee shall be payable monthly in
     arrears, beginning July 1, 1992 and continuing regularly thereafter during
     the term of this Agreement and upon the termination hereof. Such LC
     Guaranty Fee shall be in addition to any fee charged by the issuer of any
     Letter of Credit."

     5.   PAYMENTS.  All references in Section 3.4 of the Agreement to "Loan" or
"Loans" are hereby amended to be references to "Revolving Credit Loan" or
"Revolving Credit Loans" and Section 3.4 is further amended by adding thereto
the following subsection (D):

               "(D) Notwithstanding Section 3.5, any payment received on the
     Loans by Lender from or on behalf of Borrower shall first be applied to the
     payment of any principal and interest then due and payable under either
     Loan in such manner as Lender shall determine in its sole discretion, with
     the balance of any such payment being applied by Lender pursuant to the
     provisions of Section 3.5. Borrower hereby irrevocably authorizes Lender,
     in Lender's sole discretion and without any obligation, to advance to
     Borrower, and to charge to the Loan Account hereunder as a Revolving Credit
     Loan, a sum sufficient on any date to pay all principal and interest then
     due and owing on any Loan.

     6.   APPLICATION OF PAYMENTS AND COLLECTIONS. A new sentence is hereby
added to the end of Section 3.5 of the Agreement, which sentence shall read as
follows:

     "In no event shall such credit balance be applied or be deemed to have been
     applied as a prepayment of the Term Loan unless as requested by Borrower,
     but Lender may offset such credit balance against the obligations upon or
     after the occurrence of an Event of Default."

interest at a rate based upon the Base Rate."

          "Borrowing Notice - as defined in Section 2.1.(D) of the Agreement."

          "Eurodollar Base Rate - with respect to a Eurodollar Loan for the
relevant Eurodollar Interest Period, a rate per annum equal to the quotient of
the following: (a) the rate at which deposits in U.S. dollars in immediately
available funds are offered by Lender or Barclays Bank PLC to first-class banks

          shall be deemed to be made, in the following manner: (a) Borrower may
          give 

                                      -4-
<PAGE>
 
          Lender notice of its intention to borrow in the form of Exhibit K
          hereto (a "Borrowing Notice"), in which notice Borrower shall specify
          (i) the aggregate amount of such Revolving Credit Loan, (ii) the
          requested date of such Revolving Credit Loan, (iii) the Annual
          Revolving Rate selected in accordance with Section 3.1 of this
          Agreement, and (iv) where Borrower selects a Eurodollar Loan, the
          Eurodollar Interest Period applicable thereto; (b) the becoming due of
          any amount required to be paid under this Agreement as interest shall
          be deemed irrevocably to be a request for a Base Rate Loan on the due
          date in the amount required to pay such interest; and (c) the becoming
          due of any other Obligations shall be deemed irrevocably to be a
          request for a Base Rate Loan on the due date in the amount then so

          the Borrowing Notice prior to 12:00 Noon on the Business Day which is
          the requested date of such Base Rate Loan. If Borrower selects a

          United States of America in immediately available funds by wire
          transfer to such bank account as may be agreed upon by Borrower and
          Lender from time to time; and (b) the proceeds of each Loan requested
          under Section 2.1(D)(l)(b) or (c) shall be disbursed by Lender by way
          of direct payment of the relevant obligation.

     3.   INTEREST AND CHARGES.

          (a) Section 3.1(A) of the Agreement is hereby deleted, and the

          to-day shall bear interest, calculated daily at a fluctuating rate per
          annum equal to the lesser of (i) 1.5% (or such lesser percentage as
          may be provided by subsection (H) hereof) above the Base Rate (the
          "Annual Term Rate"), or (ii) the Maximum Legal Rate. The principal
          amount of the Revolving Credit Loans 

                                      -5-
<PAGE>
 
          outstanding from day-to-day shall bear interest, calculated daily, at
          the following rates per annum (individually called, as applicable, an
          "Annual Revolving Rate"): (i) each Eurodollar Loan shall bear interest
          at a rate per annum equal to the lesser of (a) 3.5% (or such lesser
          percentage as may be provided by subsection (H) hereof) above the
          Eurodollar Base Rate for the Eurodollar Interest Period applicable
          thereto, or (b) the Maximum Legal Rate, and (ii) each Base Rate Loan
          shall bear interest at the lesser of (a) a fluctuating rate per annum
          equal to 1.0% (or such lesser percentage as may be provided by
          subsection (H) hereof) above the Base Rate, or (b) the Maximum Legal
          Rate."

          (b) Section 3.1(B) of the Agreement is hereby deleted, and the
     following shall be substituted therefor:

               "Each Base Rate Loan shall be increased or decreased, as the case
          may be, by an amount equal to any increase or decrease in the Base
          Rate, with such adjustments to be effective as of the opening of
          business on the day that any such change in the Base Rate becomes
          effective. The Base Rate in effect on the date hereof shall be the
          Base Rate effective as of the opening of business on the date hereof,
          but if this Agreement is executed on a day that is not a Business Day,
          the Base Rate in effect on the date hereof shall be the Base Rate
          effective as of the opening of business on the last Business Day
          immediately preceding the date hereof. Interest on the Loans shall be
          calculated daily, based on the actual days elapsed over a 360 day
          year. Further, for the purpose of computing interest, all items of
          payment received by Lender shall be applied by Lender (subject to
          final payment of all drafts and other items received in form other
          than immediately available funds) against the obligations on the first
          Business Day after receipt. The determination of when a payment is
          received by Lender will be made in accordance with Section 3.5."

          (c) Section 3.1(H) of the Agreement is hereby deleted, and the
     following shall be substituted therefor:

               "(H) So long as no Default or Event of Default has occurred, in
          the event that Borrower achieves the performance factors described
          below as of each of the calculation dates specified below, then the
          Applicable Rate shall be reduced as follows:

               (i) Performance Factors to be Achieved as of October 31, 1995. So
          long as no Default 


                                      -6-
<PAGE>
 
          or Event of Default has occurred, and so long as Borrower achieves the
          performance factors set out below, upon receipt and review by Lender
          of the audited financial statements of Borrower provided pursuant to
          Section 9.1(J) demonstrating compliance with the following performance
          factors, the Applicable Rate shall be reduced by 0.25%. Such reduction
          shall (a) with respect to Base Rate Loans, be made effective November
          1, 1995 by (i) crediting the Loan Account by the difference between
          the amount of interest paid by Borrower to Lender since such effective
          date and the amount of interest which would have been paid by Borrower
          to Lender since such effective date had the Applicable Rate been so
          reduced, and (ii) recalculating all accrued but unpaid interest, and
          all interest to accrue with respect to future transactions, at the
          Applicable Rate as so reduced, and (b) with respect to Eurodollar
          Loans, be effective only for Eurodollar Loans requested after the date
          on which Lender has received and reviewed Borrower's audited financial
          statements demonstrating compliance with the performance factors set
          out below. The performance factors required to be achieved as of
          October 31, 1995 in order to reduce the Applicable Rate are as
          follows:

                    (A) The Average Daily Availability for the six months ending
               October 31, 1995 shall equal or exceed thirty percent (30%) of
               the Average Daily Loan Balance for such period;

                    (B) The Adjusted Net Earnings from operations, plus taxes
               (to the extent deducted therefrom), for the year ending October
               31, 1995 shall be at least $1,800,000; and

                    (C) Borrower's Leverage Ratio as of October 31, 1995 shall
               not exceed 3.8 to 1.0.

          Any rate reduction made pursuant to this Section 3.1(H)(i) shall
          remain in effect only for so long as no Default or Event of Default
          has occurred and is continuing and Borrower maintains the Leverage
          Ratio described in (C) above."

     4.   EURODOLLAR LOANS.  The following Section 3.7. is hereby added to the
Agreement as follows:

               "3.7. Additional Provisions Regarding Eurodollar Loans.

                    (A) Selection of Eurodollar Loan. Borrower may select a
          Eurodollar Base Rate with respect to all or any portion of the
          Revolving Credit Loans as provided in this Section 3.7.; provided,
          however, that (i) each Eurodollar Loan shall be in a principal amount
          of not less than $1,000,000 (and, if greater than $1,000,000, in
          integral multiples of $100,000), (ii) if Borrower shall elect to have
          all or a portion of the Revolving Credit Loans bear interest at a
          Eurodollar Base Rate, the aggregate principal amount of Eurodollar
          Loans outstanding shall be no less than $1,000,000, (iii) no more than
          four (4) Eurodollar Interest Periods may be in existence at any one
          time, and (iv) Borrower may not select a Eurodollar Base Rate for a
          Revolving Credit Loan if there exists a Default or Event of Default.
          The Borrower shall select Eurodollar Interest Periods with respect to
          Eurodollar Loans so that no Eurodollar Interest Period expires after
          the end of the original Term, or if extended pursuant to Section 3.3,
          any Renewal Term. An outstanding Base Rate Loan may be converted to a
          Eurodollar Loan at any time subject to the provisions of this Section
          3.7.

                    (B) Interest on Eurodollar Loans. Each Eurodollar Loan shall
          bear interest from and including the first day of the Eurodollar
          Interest Period applicable thereto (but not including the last day of
          such Eurodollar Interest Period) at the interest rate determined as
          applicable to such Eurodollar Loan, but interest on such Eurodollar
          Loan shall be payable as provided in Section 3.4. If at the end of an
          Eurodollar Interest Period for an outstanding Eurodollar Loan Borrower
          has failed to deliver to Lender a new Borrowing Notice with respect to
          such Eurodollar Loan or to pay such Eurodollar Loan, then such
          Eurodollar Loan shall be converted to a Base Rate Loan on and after
          the last day of such Eurodollar Interest Period and shall remain a
          Base Rate Loan until paid or until the effective date of a new
          Borrowing Notice with respect thereto.

                    (C) Availability of Eurodollar Loans. If (i) Lender
          determines that maintenance of any of its Eurodollar Loans would
          violate any applicable law, 


                                      -8-
<PAGE>
 
          rule, regulation or directive, whether or not having the force of law,
          and (ii) there exists no other branch or office of Lender through
          which such Eurodollar Loans could be maintained without any such
          violation or other disadvantageous implications to Lender, Lender
          shall suspend the availability of Eurodollar Loans and require any
          Eurodollar Loans outstanding to be repaid; or if Lender determines
          that (i) deposits of a type or maturity appropriate to match fund
          Eurodollar Loans are not available or (ii) the Eurodollar Base Rate
          does not accurately reflect the cost of making a Eurodollar Loan, then
          Lender shall suspend the availability of Eurodollar Loans after the
          date of anY such determination.

                    (D) Funding Indemnification. If any payment of a Eurodollar
          Loan occurs on a date which is not the last day of the applicable
          Eurodollar Interest Period, whether because of acceleration,
          prepayment or otherwise, or a Eurodollar Loan is not made on the date
          specified by Borrower because Borrower has not satisfied the
          conditions precedent to such Eurodollar Loan contained in this
          Agreement or has otherwise breached the terms of this Agreement,
          Borrower will indemnify Lender for any loss or cost incurred by it
          resulting therefrom, including without limitation any loss or cost in
          liquidating or employing deposits acquired to fund or maintain the
          Eurodollar Loan.

                    (E) Lender Statements: Survival of Indemnity. Within sixty
          (60) days of the date upon which Lender suspends the availability of
          Eurodollar Loans under Section 3.7(C) hereof or learns of any loss or
          cost for which Borrower has indemnified Lender under Section 3.7(D)
          hereof, Lender shall deliver a written statement as to the amount due
          under Section 3.7(C) or (D). Such written statement shall set forth in
          reasonable detail the calculations upon which Lender determined such
          amount and shall be final, conclusive and binding on Borrower in the
          absence of manifest error. Determination of amounts payable under such
          Sections in connection with a Eurodollar Loan shall be calculated as
          though the Lender funded its Eurodollar Loan through the purchase of a
          deposit of the type and maturity corresponding to the deposit used as
          a reference in determining the Eurodollar Base Rate applicable to such
          Eurodollar Loan whether in fact that is the case or not. Unless
          otherwise provided herein, the amount specified in the written
          statement shall be payable on demand after receipt by Borrower of the
          written statement."

performance factors ('Performance Factors') set out below, upon receipt and
review by Lender of the audited financial statements of Borrower provided
pursuant to Section 9.1(J) demonstrating compliance with (x) the hereinafter
described Level I Performance Factors, the Applicable Rate shall be reduced by
0.25%; (y) the hereinafter described Level II Performance Factors, the

Rate with respect to the Base Rate Loans (as distinguished from the Eurodollar

Maximum Legal Rate. Such Performance Factors shall be measured on each of
October 31, l995, October 31, 1996, October 31, 1997 and October 31, 1998
(hereinafter, a 'Calculation Date'). Such reduction shall (a) with respect to
Base Rate Loans, be made effective on the November 1 following the relevant
Calculation Date, by (i) crediting the Loan Account by the difference between
the amount of interest paid by Borrower to Lender since such effective date and
the amount of interest which would have been paid by Borrower to Lender since
such effective date had the Applicable Rate been so reduced, and (ii)
recalculating all accrued but unpaid interest, and all interest to accrue with
respect to future transactions, at the Applicable Rate, as so reduced, and (b)
with respect to Eurodollar Loans, be effective only for Eurodollar Loans
requested after the date on which Lender has received and reviewed Borrower's
audited financial statements demonstrating compliance with the respective
Performance Factors set out below. The respective Level I Performance Factors,
Level II Performance Factors and Level III Performance Factors required to be
achieved as of the relevant Calculation Date, in order to attain the relevant
reduction in the Applicable Rate as described above, are as follows:

                          Level I Performance Factors:

               (A) The Average Daily Availability for the six months ending on
the relevant Calculation Date shall equal or exceed twenty percent (20%) of the
Average Daily Loan Balance for such period;
<PAGE>
 
               (B) The Adjusted Net Earnings from operations, plus taxes (to the
extent deducted therefrom), for the year ending on the relevant Calculation
Date shall be at least $1,800,000; and

               (C) Borrower's Leverage Ratio as of the relevant Calculation Date
shall not exceed 4.S to l.0.

                         Level II Performance Factors:

               (A) Achievement of Level I Performance Factors.

               (B) The Average Daily Availability for the six months ending on
the relevant Calculation Date shall equal or exceed twenty percent (20%) of the
Average Daily Loan Balance for such period;

               (C) The Adjusted Net Earnings from operations, plus taxes (to the
extent deducted therefrom), for the year ending on the relevant Calculation Date
shall be at least $3,000,000; and

               (D) Borrower's Leverage Ratio as of such Calculation Date shall
not exceed 4.0 to l.0.

                         Level III Performance Factors:

               (A) Achievement of Level II Performance Factors.

               (B) The Average Daily Availability for the six months ending on
the relevant Calculation Date shall equal or exceed thirty percent (30%) of the
Average Daily Loan Balance for such period;

               (C) The Adjusted Net Earnings from operations, plus taxes (to the
extent deducted therefrom), for the year ending on the relevant Calculation Date
shall be at least $5,000,000; and

               (D) Borrower's Leverage Ratio as of such Calculation Date shall
not exceed 3.0 to l.0.

     Borrower shall be entitled to the benefits of the respective rate reduction
at the first such Calculation Date it achieves the respective Performance
Factors necessary for such rate reduction and may achieve more than one level of
rate reduction at a specific Calculation Date. For example, if at October 31,
l995, Borrower is able to satisfy all of the Level I Performance Factors, Level
II Performance Factors, and Level III Performance Factors, Borrower shall
thereupon become entitled to the rate reduction provided for in connection with
each such Performance Factors level.
<PAGE>
 
     Any respective rate reduction made pursuant to this Section 3.1(H)(i) shall
remain in effect only for so long as no Default or Event of Default has occurred
and is continuing and Borrower maintains the respective Leverage Ratio required
for such rate reduction described above. If Borrower loses the benefit of a
specific rate reduction it shall have the opportunity to again achieve the
relevant rate reduction by meeting the relevant Performance Factors at the next
Calculation Date."

determination. The foregoing notwithstanding, in the event deposits of U.S.
dollars in amounts approximately equal to the outstanding principal balance of
all Revolving Credit Loans for a one month period are not offered to Bank in the

'Eurodollar Base Rate' shall be the thirty (30) day London interbank offered
rate as published from time to time by the Wall Street Journal, or if not

     4.   INTEREST AND CHARGES. Effective as of the date of the execution of
this Amendment:

          (a) Section 3.1(A) of the Agreement is amended and restated to read as
follows:

                                       4
<PAGE>
 
     "The principal amount of the Term Loan outstanding from day-to-day shall
bear interest, calculated daily at a fluctuating rate per annum, equal to the
lesser of (i) l.0% above the Base Rate (the 'Annual Term Rate') or (ii) the
Maximum Legal Rate. The principal amount of the Revolving Credit Loans
outstanding from day-to-day shall bear interest, calculated daily, at the
following rates per annum (individually called, as applicable an 'Annual
Revolving Rate'): (i) each Eurodollar Loan shall bear interest at a rate per
annum equal to the lesser of (a) 2.75% (or such lesser percentage as may be
provided by subsection (H) hereof) above the Eurodollar Base Rate or (b) the
Maximum Legal Rate, and (ii) each Base Rate Loan shall bear interest at the
lesser of (a) a fluctuating rate per annum equal to 0.5% above the Base Rate, or
(b) the Maximum Legal Rate. Borrower shall deliver to Lender a notice electing
to have the Revolving Credit Loans made hereunder accrue at the Eurodollar Base
Rate or the Base Rate (plus, in each case, the percentages set forth above), and
Borrower may subsequently change the manner in which interest accrues on the
Revolving Credit Loans (from Eurodollar Base Rate to Base Rate or from Base Rate
to Eurodollar Base Rate) by written notice to Lender, each such change being
effective three (3) Business Days after receipt of such notice by Lender. All
outstanding Revolving Credit Loans shall accrue interest in the same manner.
Borrower may not elect to have a portion of the Revolving Credit Loans accrue
interest based upon the Eurodollar Base Rate, and a portion accrue interest
based upon the Base Rate (plus, in each case, the percentages set forth above).
Until Lender receives the first such notice hereunder, all Revolving Credit
Loans shall be Base Rate Loans. Notwithstanding anything herein to the contrary,
unless otherwise agreed by Lender, the becoming due of any obligations (other
than requested Revolving Credit Loans) shall be deemed irrevocably to be a
request by Borrower for a Base Rate Loan on the due date on the amount then so
due."

          (b) Section 3.1(B) of the Agreement is amended and restated to read as
follows:

     "The interest rate on each Base Rate Loan shall be increased or decreased,
as the case may be, by an amount equal to any increase or decrease in the Base
Rate, with such adjustments to be effective as of the opening of business on the
day that any such change in the Base Rate becomes effective. The Base Rate in
effect on the date hereof shall be the Base Rate effective as of the opening of
business on the date hereof, but if this Agreement is executed on the day that
is not a Business Day, the Base Rate in effect on the date hereof shall be the
Base Rate effective as of the opening of business on the last Business Day
immediately preceding the date hereof. The interest rate on each Eurodollar Loan
shall be increased or decreased, as the case may be, by an amount equal to any
increase or decrease in the Eurodollar Base Rate, with such adjustments to be
effective as of the opening of business on the day that any such change in the
Eurodollar Base Rate becomes effective. The Eurodollar Base Rate in effect on
the date hereof shall be the Eurodollar Base Rate effective as of the opening of
business on the date hereof, but if this Agreement is executed on a day that is
not a Business Day, the Eurodollar Base Rate in effect on the date hereof shall
be the Eurodollar Base Rate effective as of the opening of business on the last
Business Day immediately preceding the date hereof.

                                       5

Interest on the Loans shall be calculated daily, based on the actual days
elapsed over a 360 day year. Further, for the purpose of computing interest, all
items of payment received by Lender shall be applied by Lender (subject to final
payment of all drafts and other items received in form other than immediately
available funds) against the obligations on the first Business Day after
receipt. The determination of when a payment is received by Lender will be made
in accordance with Section 3.5."

          (c) Section 3.1(H) of the Agreement is amended by deleting from
Subsection thereof the phrase "for the Eurodollar Interest Period applicable
thereto".

          (d) Section 3.7(A) and Section 3.7(B) of the Agreement are hereby
deleted in their entirety.

          (e) Section 3.7(D) of the Agreement is amended by deleting therefrom
the phrase "any payment of a Eurodollar Loan occurs on a date which is not the
last day of the applicable Eurodollar Interest Period, whether because of
acceleration, prepayment or otherwise, or".

     5.   CONDITIONS TO ADVANCES UNDER TERM LOAN. Effective as of the date of
execution of this Amendment, Section l0.3 of the Agreement is hereby amended by
deleting the present subsection (F) of such Section l0.3, and substituting

     such other satisfactory environmental studies, reports, and reviews as

          accrue interest in the same manner. Borrower may not elect to have a
          portion of the Revolving Credit Loans accrue interest based upon the
          Eurodollar Base Rate, and a portion accrue interest based upon the
          Base Rate (plus, in each case, the percentages set forth above).
          Borrower may not elect to have a portion of the outstanding principal
          amount of the Term Loan accrue interest based upon the Eurodollar Base
          Rate, and a portion accrue interest based upon the Base Rate (plus, in
          each case, the percentages set forth above). Notwithstanding anything
          herein to the contrary, unless otherwise agreed by Lender, the
          becoming due of any obligations (other than requested Revolving Credit
          Loans) shall be deemed irrevocably to be a request by Borrower for a
          Base Rate Loan on the due date on the amount then so due."

   may terminate this lease with respect to any Vehicle at any time upon return
   thereof and payment of damages as specified in paragraphs 12 and 13 hereof or
   upon such other terms and conditions as may then be mutually agreed to in
   writing by Lessor and Lessee.

        12. RETURN OF VEHICLE.  Upon the expiration or earlier termination by 
either party of the term of this lease with respect to any Vehicle:

a. Return. Unless the Lessee purchases the Vehicle, pursuant to paragraph 13a,
   the Lessee shall return the same to the Lessor, in as good condition as when
   first received, ordinary wear and tear excepted, at (i) the place where the
   Lessee first received the Vehicle, (ii) to Lessor's principal place of
   business if different from (i) above, or (iii) to such location as may be
   designated by Lessor.

b. Repossession. If Lessee neither purchases nor returns the Vehicle, the Lessor
   may repossess the same at any time wherever the same may be located, and may
   enter upon any premises of Lessee for the purpose, and shall hold the same
   when so repossessed free and clear of this lease and any rights of Lessee
   therein.

c. Lost Vehicle. If the Vehicle is lost, stolen or destroyed or is declared a
   total constructive loss (subject to Lessor's agreement as to such condition),
   Lessee shall promptly notify Lessor thereof and hold any wreckage for
   disposal by Lessor, and the Vehicle shall be deemed surrendered to Lessor as
   of Lessor's receipt of such notice. Lessor shall promptly cause any wreckage
   to be sold. Any wreckage not held by Lessee for disposal by Lessor shall be
   deemed sold at a price of zero dollars.

d. Sums Due. Upon any purchase, return or repossession, Lessee shall promptly
   pay Lessor all Monthly Rentals and other sums payable hereunder with respect
   to the Vehicle up to the time of such purchase, return or repossession.

e. Resale. As provided in paragraph 13a, Lessor shall sell the Vehicle and, if
   Net Proceeds are less than Depreciated Value, Lessee shall pay the difference
   to Lessor; if Net Proceeds exceed Depreciated Value, Lessor shall pay to
   Lessee the portion of such excess proceeds as agreed upon.

        13. DAMAGES UPON EARLY TERMINATION.  Upon the termination of this lease 
by either party as to any Vehicle prior to the expiration of its lease term, the
Lessee shall promptly pay Lessor all damages suffered by the Lessor by reason of
such termination (or by reason of any breach of this lease by Lessee). Such
damages shall include damages determined as follows:

a. Purchase or Resale. The Lessee shall promptly purchase and pay for the
   Vehicle, if Lessor so requests, at its Depreciated Value (i.e., its Original
   Value as specified in Schedule A, less a sum equal to its Monthly
   Depreciation specified in Schedule A, multiplied by the number of Monthly
   Rentals that have been paid). Lessee shall also take over any insurance on
   the Vehicle paid for by Lessor and pay Lessor for the unearned cost thereof
   on a daily apportionment basis. If the Lessor doe not request Lessee to
   purchase the Vehicle or if the Vehicle is not so purchased, Lessor shall sell
   the Vehicle (or wreckage under paragraph 12d) within 30 days after its
   surrender or repossession (or such other period a the parties may agree
   upon). The sale may be public or private and with or without notice to
   Lessee, shall be at wholesale, and shall be only for cash payable in full
   upon delivery of the Vehicle and its title papers to the purchaser. If the
   Net Proceeds of the sale are less than the Depreciated Value of the Vehicle
   such deficiency shall constitute part of Lessor's damages; if such Net
   Proceeds exceed Depreciated Value, the excess shall constitute an offset to
   Lessor's other damages.

        (i) "Net Proceeds" shall mean the amount received on the sale, less all
            direct expenses of Lessor in preparing and holding the Vehicle for
            sale and selling it and less all sums due Lessor under paragraph 12d
            if not otherwise paid, and less all debts incurred by Lessee which,
            if not paid, might constitute a lien on the Vehicle or a liability
            of Lessor.

b. Lost Income. Lessee shall pay Lessor as liquidated damages for loss of income
   a sum equal to the Monthly Rental less the amount of the Monthly Depreciation
   for each month of the original term of the lease remaining after the
   termination.

c. Expenses. Lessee shall reimburse Lessor all costs and expenses (including
   reasonable attorney's fees) incurred by Lessor in enforcing Lessor's rights
   hereunder.

d. Remedies Not Exclusive. Repossession and resale of any Vehicle shall not
   affect Lessor's rights to recover any damages from Lessee, and Lessor's
   rights and remedies in the event of any breach, termination or expiration of
   this lease with respect to any Vehicle (including damages herein specified)
   shall not be deemed exclusive but shall be cumulative and in addition to all
   other rights and remedies in Lessor's favor existing by law.

        14. ADDITIONAL VEHICLES; EXTENDED TERM.  Additional Vehicles may be 
included in this lease by addenda to Schedule A mutually executed by Lessor and 
Lessee from time to time.

        15. FORCE MAJEURE and NO CONSEQUENTIAL DAMAGES. Lessor shall not be 
liable for any failure or delay in delivering any Vehicle, or in performing any 
provision hereof, due to fire or other casualty, labor difficulty, governmental 
restriction or any cause beyond Lessor's control. In no event shall Lessor be 
liable for any loss of profits, other consequential damages or inconvenience due
to any theft, damage, loss, defect or failure of any Vehicle or the time 
consumed in recovering, repairing, servicing or replacing the same, and there 
shall be no abatement or apportionment of rental during such time.

        16. LEASE ONLY. This agreement is one of leasing only and Lessee shall 
not have or acquire any right, title or interest in any Vehicle except the right
to use the same as provided in this agreement.

        17. PROCEDURE on ACCIDENTS. Lessee shall furnish to Lessor and to the 
automobile liability insurer of any Vehicle, within 24 hours, a report of any 
accident involving the Vehicle on the form furnished by such insurer. If any 
claim is made or action commenced for death, personal injury or property damage,

thereof and furnish Lessor a copy of every demand, notice, summons, process and 
pleading received in connection therewith and cooperate with Lessor and the 
insurer in defending the same.

        18. ENTIRE AGREEMENT, LAW of AGREEMENT, ASSIGNMENT and SUBORDINATION. 
This lease constitutes the entire agreement between the parties and may not be 
changed except by an instrument in writing signed by the party to be charged.

        This lease may not be assigned, or any Vehicle subleased, by Lessee 
without Lessor's prior written consent.

        Lessor may assign this lease and any or all rentals or other sums 
payable by Lessee hereunder; upon notice of such an assignment. Lessee shall pay
such sums to the assignee without offset, counterclaim or defense of any kind. 
Lessor may also execute any type of security instrument with respect to any 
Vehicle and Lessee's rights shall be subordinate to the rights of the holder of 
such instrument. No assignment, or execution of a security instrument, by Lessor
shall relieve Lessor from any liability hereunder.

        The parties intend this agreement to be executed in, and interpreted, 
construed and enforced in accordance with the laws of, the state of Lessor's 
place of business first above stated.

        19. COUNTERPARTS and RECORDING. Lessor and Lessee shall execute this 
lease in as many counterparts (each constituting an original but together 
constituting only one agreement) as may be reasonably necessary for recording or
filing in any governmental office. Lessee shall pay the fees and Lessor's 
out-of-pocket expenses for any such recording or filing required by law and 
shall pay any stamp or documentary taxes assessed upon this lease.

        IN WITNESS WHEREOF, the parties have duly executed this lease
this __________________ day of ____________________, 1989.

                                   ---------


     THIS AGREEMENT ("Agreement") is made and entered into as of the 30th day of
October, 1997, by and between Consolidated Investment Services, Inc.
("Consolidated") and Red Man Pipe & Supply Co. ("Red Man").

                                   RECITALS
                                   --------

     On the 12th day of July, 1988, Otter, Inc., an Oklahoma corporation
("Otter"), and Red Man entered into a Financial Agreement, which agreement was
on October 24, 1990, amended by an agreement between those parties (the "Amended
Financial Agreement"); and Vinson Supply Company, a Delaware corporation
("Vinson") and Red Man entered into a Purchase Agreement as of the 2nd day of
March, 1995.

     Consolidated is successor in interest to the rights and obligations of
Otter and Vinson under both the Amended Financial Agreement and the Purchase
Agreement.
     Consolidated is the holder of the following securities of Red Man:

     23,276 shares Class A Common Stock
     34,344 shares Class B Common Stock
     2,000 shares Class C Preferred Stock

     Red Man anticipates a public offering (the "Offering") of approximately
thirty percent (30%) of its Common Stock computed after completion of the
Offering, and assuming exercise of the underwriter's over allotment option.  The
public offering will consist only of Class A Common Stock.

                                       1
<PAGE>
 
     IT IS THEREFORE AGREED AS FOLLOWS:

     1.  Prior to the Offering, the 34,344 shares of Class B Common Stock held
by Consolidated will be exchanged for 34,344 shares of Class A Common Stock.

     2.  That 82,000 shares of Class A Common Stock which were originally issued
to Lewis B. Ketchum and are now held by or for the Ketchum family, will be
exchanged for 82,000 shares of Class B Common Stock.

     3.  The Articles of Incorporation of Red Man will be amended to:

     A.   Accommodate the exchange of Class B Common Stock for Class A Common
          Stock and the exchange of eighty-two thousand (82,000) shares of Class
          A Common Stock beneficially owned by the Ketchum Family for Class B
          Common Stock;

     B.   Increase authorized capital to allow a stock split in order that
          present stockholders will own approximately seventy percent (70%) of
          the then outstanding capital stock of Red Man after the Offering;

     C.   Increase authorized capital to raise authorized capital for not less
          than the Offering;

     D.   Assign ten (10) votes for each share of Class B Common Stock and one
          (1) vote for each share of Class A Common Stock.

                                       2
<PAGE>
 
     4.  The Amended Financial Agreement and the Purchase Agreement shall be of
no further force and effect, except as follows:

     A.   All leases of real and personal property between the parties hereto
          and their predecessors in interest shall remain in full force and
          effect.

     B.   The characteristics, rights and preferences of Class C Preferred Stock
          as stated on the Certificate representing those shares shall remain in
          full force and effect.

     5.  Prior to the initial stock offering, the Board of Directors of Red Man
is authorized to establish and approve an incentive plan for not greater than
five percent (5%) of the authorized Class A Common Stock to be used for
incentive or non-qualified stock options or other stock incentive programs for
employees.

     6.  That at the time of, or prior to the Offering, Red Man will redeem and
retire the Preferred Stock owned by Consolidated at the face amount thereof,
with accrued dividends to the date of redemption.

     7.  That the Board of Directors of Red Man shall promptly take all action
required to cause the Red Man Common Stock owned by Consolidated to be
registered under the Securities Act of 1933 and/or the Oklahoma Securities Act
upon request by Consolidated, 

                                       3
<PAGE>
 
which request shall not be made until after the expiration of two (2) years from
the date of the Offering. Further and notwithstanding the foregoing, at any time
after the Offering, if the Board of Directors of Red Man causes or permits any
additional shares of Red Man stock to be registered under the Securities Act of
1933 and/or the Oklahoma Securities Act, Consolidated shall have the right to
have its Red Man Common Stock registered simultaneously therewith.

     8.  That should an Offering of Red Man Class A Common Stock not occur on or
before March 31, 1998, this Agreement will terminate and immediately thereafter
the parties shall be required to take such action as is necessary to effect the
restoration to the positions of the parties which existed on October 28, 1997.

     AGREED TO effective the 30th day of October, 1997.
