ITEM 1.   BUSINESS

GENERAL

ERC Industries, Inc., a Delaware corporation (the "Company"), is an oilfield
service company engaged in the manufacture, remanufacture and servicing of
oilfield wellhead equipment.

In October of 1992, the Company's predecessor, ERC Industries, Inc., a Delaware
corporation ("Old ERC") incorporated the Company as a wholly owned subsidiary.
Old ERC merged into this wholly owned subsidiary after the stockholders of Old
ERC approved the transaction at a special meeting held on April 16, 1993.
Effective with the merger, the Company changed its name to ERC Industries, Inc.
For further discussion, see "Merger" below.

On December 10, 1992, John Wood Group PLC ("Wood Group"), a corporation
registered in Scotland and incorporated under the laws of the United Kingdom,
completed the purchase of approximately 47% of the issued and outstanding shares
of Common Stock of Old ERC.  In March, 1996, Wood Group purchased additional
shares and now owns approximately 58% of the Company. The Company has been
advised that Wood Group is recognized as the United Kingdom's largest indigenous
oil service company, having over 20 years experience in servicing the oil and
gas industries. For further discussion, see "Merger - Background."

On November 16, 1993, the Company entered into an agreement with Barton
Industries, Inc. ("Barton") of Shawnee, Oklahoma, and three secured creditors of
Barton.  The agreement provided for the purchase of Barton's valve business and
certain of its assets.  The Barton business is now a division of the Company
known as "Barton Wood," the name of the founder of the valve and the name of the
principal stockholder of the Company.  For a further discussion, see "Barton
Wood Business Development" and "Barton Wood Operations" below and Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

Where the context requires, the term "Company" as used herein shall also refer
to Old ERC.


OPERATIONS

The equipment and components offered by the Company are comprised of items
manufactured by the Company in its own facilities, consisting principally of
wellhead equipment and valves, and items acquired and reconditioned under the
Company's wellhead management program and new products acquired from other
manufacturers.  The services offered by the Company consist of reconditioning
out-of-service equipment for others, installations and repairs.  The Company
also leases certain oilfield equipment to customers.

                                       3

ERC'S OPERATIONS

Old ERC's predecessor, Equipment Renewal Company, was founded in 1962 based on
the concept of remanufacturing and reemploying used, out-of-service wellhead
equipment.  Wellhead equipment is designed to support the casing and production
pipe on a completed well and includes casing heads, tubing heads and casing and
tubing hangers.  Valves are assembled with other components into a device known
as the "Christmas Tree" which is mounted on the wellhead equipment and is used
to control pressure and the flow of oil and gas from producing wells.  A
substantial portion of the Company's oilfield equipment business is conducted
through surplus wellhead equipment management programs.  Under these programs,
the Company collects out-of-service equipment at the wellhead or accepts
delivery from a given customer at a branch location.  All equipment is inspected
by the Company and classified based upon its condition and degree of
obsolescence upon receipt at the Company's service center.  If deemed
salvageable, the equipment is cleaned and disassembled, and, if needed, heat
treated.  Components are either replaced or repaired, usually by machining and
welding.  The equipment is then remachined on the Company's lathes, boring
mills, radial drills, milling machines and grinding machines to new equipment
standards.

The reconditioned equipment may then be reemployed by the customer in accordance
with its requirements.  Reconditioned equipment is accompanied by a warranty
similar to a manufacturer's warranty.  The customer is charged for this
reconditioning service based on an established price schedule, in addition to
charges for receiving, inspecting and classifying the equipment.  If the
customer so desires, the Company may purchase the customer's used equipment for
resale to other customers.  The resale price of the equipment is typically based
upon a percentage of the current list price of new equipment.  The payment for
the customer's equipment may be in the form of a merchandise credit to be
applied towards future purchases by that customer.

The branches, sales and service offices of the Company act, in part, as clearing
houses for oilfield operators.  If the operator, at a particular location,
requires a unique component held by the Company on behalf of another customer,
the Company may contact the customer and effect a purchase from the customer
that has the equipment and then resell the equipment to the customer that is in
need of it.

In addition to remanufacturing customer equipment, the Company purchases used
equipment for its own account from various sources which it then remanufactures
for sale.

The Company manufactures a complete line of wellhead equipment. Forgings and
other components and supplies required for manufacturing are available from
numerous sources, and the Company does not presently depend on any single
source.

As of March 1996, the Company's wellhead and related equipment operations are
conducted from 21 domestic locations, four international locations, and three
distributorships.  The Company's manufacturing facilities are located in
Shawnee, Oklahoma.

BARTON WOOD OPERATIONS

The Barton Wood Division has expanded its capabilities and is now able to offer
a complete line of gate valves and conventional wellhead equipment.  Valves are
available in 1-13/16" to 16" sizes for working pressures from 300 p.s.i. to
15,000 p.s.i. and are produced in eight basic material trims. Barton Wood also
produces "custom trims" to meet individual customer requirements.  The division
is licensed by the API to distribute its products with the API monogram in
accordance with API Specification 6A (wellhead valves), Specification 6D
(pipeline valves) and Specification 14D (surface safety valves for offshore
use).  The use of API monogram is considered by management to be essential to
compete successfully in the oil and gas valve market.  The Company achieved ISO
9001 registration for its manufacturing facility during 1995.  This provides
assurances, required by many customers, that ERC Barton Wood meets International
quality standards.

To manufacture products, Barton Wood purchases major raw material components
from foundries, forging houses, and steel suppliers, then machines such
materials into finished products using CNC machines, which are essentially
computer controlled lathes and machine centers, and other conventional machine
tools.  Special heat treatment and surface conditioning are applied as
appropriate to individual components to improve product performance and to meet
varying service condition requirements.

Barton Wood valves are typically used in the oil and gas industry on producing
wellheads, pipelines, processing plants, secondary and tertiary recovery
systems, and in gas storage fields.  The Barton Wood valve has also been used to
control many other common gases and liquids.

In addition to the Oil and Gas sectors, Barton Wood is a participant in applying
its products to the growing Geothermal market.  The Company's high temperature
valve design enjoys a technical preference for Geothermal Wellhead applications.
The valve is also used in pipelines between steam producing wells and power
plants.

Barton Wood also produces valves for steam injection, carbon dioxide service and
a line of chokes used to control the flow of fluid or gas through an orifice.

The Company's strategy, with regard to the Barton Wood division, is to continue
expanding its presence in the domestic market as well as to advance its presence
in the international market. Barton Wood opened sales offices in Europe, the
Middle East, Latin America, Australia and Southeast  Asia during 1995.  These
locations are managed by seasoned industry professionals with many years
international experience.  This local presence has generated a high degree of
customer interest and a growing backlog.  The division intends to focus on
increasing international sales in 1996.

                                       5

ENGINEERING RESEARCH AND DEVELOPMENT

The Company is involved in an active R & D program.  Barton Wood expects to file
for and receive patents on new products aimed at growth in target geographic and
product markets.  New wellhead products were launched during 1995 that enable
additional market participation.  Additionally, value engineering projects
focused on a broad range of cost reductions in 1996.

PATENTS AND SERVICE MARKS

The Company holds several patents and trademark/service marks.  Many of these
are registered with the United States Patent and Trademark Office and expire at
various times through 2003.  The Company believes that its patents and
trademark/service mark are important to its marketing efforts.


SALES AND MARKETING

The Company conducts its operations from its branch facilities located in most
major oil and gas producing areas in the United States requiring wellhead
equipment.  Each branch facility maintains a substantial inventory of new and
remanufactured wellhead equipment, a complete machine shop, welding and heat
treatment facilities and a staff of trained sales and service personnel.  This
gives each branch the capability to provide a full range of products and
services, including new or remanufactured equipment sales, renewals of customer
equipment, a wellhead equipment management program and an installation and
service capability.  Sales and service offices are located in areas served by a
branch but which require additional sales and service effort.  A sales and
service office operates in conjunction with a branch.  Sales offices are located
in metropolitan areas, principally Houston, Dallas, New Orleans, Denver and
Tulsa, where customers are typically headquartered or maintain regional offices.

The Company's marketing program emphasizes new equipment, remanufactured
equipment (with a new equipment warranty) available at a substantial cost
savings and surplus equipment management programs, along with installation and
service capabilities, renewal and repair services and a close proximity to most
customer locations.

The Company also offers a computer-based equipment management system, which
provides the customer with a listing of all of its equipment nationwide.  The
system can also be customized to satisfy individual customer requirements.

                                       6

COMPETITION

Oilfield equipment is sold by many manufacturers, distributors and dealers,
including those offering used equipment.  However, the Company believes that
relatively few competitors offer programs involving maintenance, reconditioning,
storage, distribution and management of equipment such as those offered by the
Company.  In offering its programs, the Company emphasizes its ability to
provide reconditioned oilfield equipment at favorable prices while at the same
time performing services which the customer would otherwise have to perform at a
substantial cost and inconvenience.

Numerous companies, some of which have substantially greater resources than the
Company, are engaged primarily in the manufacturing, installation and
maintenance of wellheads, valves and drilling equipment as well as other types
of oilfield equipment.  In addition, some foreign manufacturers make only
valves.  Over the past several years, severe price competition, as a result of
shrinking demand, has continued to have a substantial impact on profit margins.


GOVERNMENT REGULATION

The exploration, development and production of oil and gas in the United States
is affected by comprehensive federal and state regulations including those
governing allowable rates of production, marketing, environmental matters and
pricing.


EMPLOYEES

As of February 23, 1996, the Company had 284 employees, as compared to 293
employees as of February 16, 1995.  No employees of the Company are represented
by a union.


CUSTOMERS

The Company has no customers that comprised 10% or more of its 1995 and 1994
sales.  During the eleven months ended December 31, 1993, Conoco Incorporated
contributed approximately 10% of the Company's total revenues.

MERGER

Background.  On October 15, 1992, Quantum Fund N.V. ("Quantum"), then the
Company's largest stockholder, and Warren H. Haber (then a director of the
Company), Lawrence M. Pohly and John L. Teeger (collectively referred to, with
Quantum, as the "Sellers"), along with the Company, entered into a Stock
Purchase Agreement (the "Purchase Agreement") with Wood Group, whereby the
Sellers agreed to sell, and Wood Group agreed to purchase, subject to the terms
and conditions of the Purchase Agreement, an aggregate of 6,538,686 shares of
the Common Stock of the Company ("Common Stock").

On December 10, 1992, Wood Group completed the terms of the Purchase Agreement.
On April 16, 1993, Old ERC merged into the Company after the merger was approved
by Old ERC stockholders and the Company changed its name to "ERC Industries,
Inc."  The total of 6,538,686 shares purchased by Wood Group represented
approximately 47% of the outstanding  shares of Common Stock.  In March 1996,
Wood Group purchased an additional 1,544,518 shares of Common Stock in privately
negotiated transactions.  As a result, the Wood Group currently owns 8,083,204
shares representing approximately 58% of the outstanding shares of Common Stock
of New ERC.

Certain Information Concerning Wood Group.  Wood Group is engaged in the
businesses of oilfield logistics and supplies, oilfield drilling and production
services, gas turbine overhaul and repair, engineering contracting and design
and engineering services.  Wood Group employs approximately 4,200 personnel
worldwide. Wood Group's results of operations for 1995 reflected sales of
approximately 372.4 million pounds sterling and profit on ordinary activities
before taxation of approximately 23.1 million pounds sterling (as determined in
accordance with U.K. statutory accounting principles).

Principal Reasons for the Merger.  The Company effected the Merger primarily to
preserve and maximize the Company's ability to offset taxable income with the
Company's net operating losses available for carryforwards ("NOL
Carryforwards").  Under Section 382 of the Internal Revenue Code of 1986, as
amended (the "Code"), and the Regulations issued thereunder, a corporation's
future use of its federal income tax net operating losses available for
carryforwards to future periods may be limited after the occurrence of an
"ownership change."  An ownership change is a transaction or series of
transactions resulting in an increase of more than 50 percentage points in the
percentage of ownership interests of stockholders who, before or after such
ownership change, own, directly or indirectly, stock representing 5% or more of
the aggregate fair market value of the outstanding stock of such corporation.

The Certificate of Incorporation of the Company now contains certain stock
transfer restrictions in order to seek to preserve the Company's  NOL
Carryforwards.  The Certificate of Incorporation of the Company provides that no
person who, as a result of any attempted transfer of Common Stock of the
Company, would own, directly or indirectly, Common Stock having a fair market
value equal to 5% or more of the aggregate fair market value of the outstanding
shares of Common Stock, may acquire shares of Common Stock (or options, warrants
or rights or securities exercisable, convertible or exchangeable therefor),
unless such person obtains the approval of the Board of Directors of the
Company.  Each certificate representing shares of Common Stock issued in
connection with the

                                       8
<PAGE>
 
Merger bears a legend referencing this restriction on transfer.  Approval of the
Board of Directors must be obtained by written request addressed to the
Company's Board of Directors at the address of the Company's principal executive
offices.  Any attempted transfer without Board approval (or approval of a duly
appointed committee of the Board) would be void and without effect, and the
intended transferee would be deemed to have appointed the Company as exclusive
agent to sell such shares to a transferee eligible to acquire such shares or
otherwise approved by the Board of Directors of the Company (or a committee
thereof).  All proceeds from the sale of such shares shall be remitted to such
appointed transferee.  This restriction on transfer would terminate upon the
earliest to occur of (I) December 31, 2002, (ii) the date when the existing  NOL
Carryforwards expires or (iii) the date when the NOL Carryforwards becomes
subject to the limitations of Section 382 of the Code.

As of December 31, 1995, the Company had approximately $26,444,000 of NOL
Carryforwards which could be used to offset future taxable earnings.  The Board
of Directors believes that the protection of the NOL Carryforwards is important
to the Company's results of operations and financial position since it may
permit the retention of cash flows which would otherwise go to the payment of
federal income taxes.  The NOL Carryforwards are only useful to the Company to
the extent that the Company has taxable income to offset. $23,800,000 of these
NOL Carryforwards must be used, or will begin to expire in the fiscal year
ending on December 31, 2001, and they will expire in full during the fiscal year
ending December 31, 2003.  The balance of the NOL carryforwards will expire
during the fiscal year ending December 31, 2009.  The largest portion of the NOL
Carryforwards will expire in the fiscal year ending on December  31, 2002.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

GENERAL

On June 15, 1993, the Company changed its fiscal year end from January 31 to
December 31.  As a result, the Company is comparing the twelve months ended
December 31, 1995 ("Fiscal 1995") and December 31, 1994 ("Fiscal 1994") with the
eleven months ended December 31, 1993 ("Fiscal December 1993").  A complete
recasting of Fiscal December 1993 was not prepared due to the fact that the
Company believes the eleven month fiscal period ended December 31, 1993 is
sufficiently comparable for assessing the Company's results of operations
compared to Fiscal 1995 and Fiscal 1994.  Footnote 11 of the Notes to Financial
Statements contains a comparison of the twelve months ended December 31, 1995
with the twelve months ended December 31, 1994 and 1993.

Industry wide, the average active domestic rig count as reported by Baker Hughes
Incorporated decreased 6.7% to an average of 723 in Fiscal 1995, as compared to
775 for Fiscal 1994.   The active domestic rig count as of March 15, 1996 was
693.  The average active rig count is a clear indicator of the market in which
the Company operates, based on prior years' experience.

RESULTS OF OPERATIONS
FISCAL 1995 VS. FISCAL 1994 VS. FISCAL DECEMBER 1993

The Company's revenues increased by 5.8% to $34,840,000 for Fiscal 1995 compared
with $32,926,000 for Fiscal 1994, despite a decrease in the rig count.    Fiscal
1994's revenues increased by 42.1% to $32,926,000 compared with $23,167,000 for
Fiscal December 1993, with only a marginal improvement in the average rig count.

Fiscal 1995 revenues increased by $1,914,000 over Fiscal 1994 due to a net
increase in customer activity and market share gains.  Fiscal 1994 revenues
dramatically increased over Fiscal December 1993 due to market share gains and
increased sales activity related to the valve manufacturing business and related
assets of Barton Wood, which was acquired from Barton Industries' secured
creditors on November 16, 1993, as more fully described in Item 1.  This
acquisition added revenues of approximately $4,563,000 in Fiscal 1994, compared
with $730,000 in Fiscal December 1993. All subsequent references to this
purchase shall be referred to as the "Barton Wood" acquisition.

In connection with revenues over the three year period, cost of goods sold were
$27,399,000 in Fiscal 1995, $25,058,000 in Fiscal 1994, and $16,053,000 for
Fiscal December 1993.  The gross profit percentage was 21.4% in Fiscal 1995,
compared with 23.9% in Fiscal 1994 and 30.7% in Fiscal December 1993.

Fiscal 1995's gross margin percentage was affected by unfavorable manufacturing
cost variances at the Barton Wood facility and one-time severance expenses.  The
Company has implemented certain process improvements to the Barton Wood
manufacturing facility.

                                       13
<PAGE>
 
The decrease in margins in Fiscal 1994, compared with Fiscal December 1993 was
due to (I) costs associated with the closing of the manufacturing facility in
Houston during the first two quarters of Fiscal 1994, (ii) additional fixed
costs associated with the new Barton Wood facility, (iii) cost increases in used
equipment purchased for resale, and (iv) a product mix shift toward lower-margin
products.  As anticipated, Barton Wood's new equipment sales have been at lower
margins than ERC's previous mix, effectively lowering the Company's overall
gross margin.  Additionally, as expected, there has been a shift toward new
equipment in ERC's traditional markets as the availability of used equipment for
repair has tightened.

Selling, General and Administrative expenses ("SG&A") increased by $1,079,000 to
$8,116,000 in Fiscal 1995 compared with $7,037,000 for Fiscal 1994.  This
increase is due to costs incurred to open additional domestic sales offices,
increases in international sales personnel, and a one-time relocation and
severance expense.  SG&A, as a percentage of sales, was 23.3% in Fiscal 1995 and
21.4% in Fiscal 1994.

SG&A increased to $7,037,000 in Fiscal 1994 compared with $6,063,000 in Fiscal
December 1993. Contributing to the increase was additional sales personnel and
the related expenses to advance new business and support continuing business,
additional SG&A expenses related to the Barton Wood operation and additional bad
debt reserves.  SG&A, as a percentage of sales, was 21.4% in Fiscal 1994 and
26.2% in Fiscal December 1993.

Net loss before provision for income tax was $1,048,000 in Fiscal 1995, compared
to net income of $628,000 in Fiscal 1994.  The decrease in Fiscal 1995 is
primarily due to the following factors: (i) lower gross margin percentage
resulting from unfavorable manufacturing cost variances at the Barton Wood
facility, (ii) increased SG&A costs incurred to open additional domestic sales
offices, increases in international sales personnel, and a one-time relocation
and severance expenses, and (iii) increased interest expenses due to a higher
borrowing level to support increased inventory levels.

Income before provision for income taxes was $628,000 in Fiscal 1994 down from
$1,157,000 in Fiscal December 1993.  The decrease in Fiscal 1994 was primarily
due to three factors: (I) a less favorable product mix sold during the year,
(ii) increased SG&A expenses, primarily due to the addition of Barton Wood for
the full year, and (iii) increased interest expense due to borrowings used to
fund the Barton Wood acquisition and related increased inventory levels.

Fiscal 1995, 1994 and Fiscal December 1993 include (benefit)/provisions for
income taxes of ($273,000), $264,000 and $421,000, respectively.  Of these
amounts, $5,000, $127,000 and $809,000,  respectively, represent non-cash
charges which reflect the income tax benefit of the utilization of the Company's
NOL Carryforwards arising prior to a quasi-reorganization, and is included in
the respective balance sheets as increases in additional paid-in capital.

                                       14

LIQUIDITY AND CAPITAL RESOURCES

Working capital decreased to $6,650,000 at December 31, 1995 compared with
$7,937,000 at December 31, 1994.  This was primarily due to a $2,331,000
increase in short term bank debt, a $575,000 increase in accounts payables, an
offsetting increase in inventory of $1,663,000, and an increase in accounts
receivable of $1,007,000.  The increase in receivables is a reflection of an
increase in business volume over the prior year and a slowing in payment
practices of certain of the Company's customers.  The increase in inventory was
a planned effort to increase the faster moving raw material at the Barton Wood
facility and to increase the Company's levels of used equipment inventory.  The
increase in inventories also required the Company to further utilize its bank
line of credit facility.

In connection with the Barton Wood acquisition in Fiscal December 1993, the
Company entered into a 10-year $2,500,000 note payable with one of the Barton
secured lenders.  At December 31, 1995, the note required 32 remaining quarterly
installments of $62,500, plus interest at the bank's prime rate, payable each
February, May, August and November 16.  The note is collateralized by specified
general intangibles and proprietary rights (including certain patents and
trademarks).  The agreement contains cross-default provisions to the Company's
bank line of credit agreement.

The Company amended its line of credit in July 1995, effectively increasing its
line of credit by $1,000,000.  The loan facility now provides for maximum
borrowings of the lesser of $4,000,000 or eligible trade accounts receivable and
inventory (as defined in the line of credit).  Interest on outstanding balances
are payable monthly at the bank's prime rate minus one-half percent.  At
December 31, 1995 the bank's prime rate was 8.5%.  The Company also amended its
loan facility on December 7, 1995 to change the covenant of maximum debt to
total net worth from a 1 to 1 ratio to 1.2 to 1.  The facility is collateralized
by trade accounts receivable and inventory. Additionally, the terms of the
agreement restrict the Company from paying cash dividends.  At December 31,
1995, loan amounts outstanding under the agreement were $2,425,000.  In
addition, the Company had outstanding, against the revolving line of credit,
irrevocable letters of credit amounting to approximately $175,000.  At December
31, 1995, the Company's maximum amount available for additional borrowings was
$1,400,000.

Subsequent to December 31, 1995, the loan facility has been amended to extend
the line of credit through June 30, 1996.  Management intends to either continue
obtaining extensions on the current line of credit or negotiate a new long term
credit agreement depending on which is more advantageous for the Company.

Pursuant to the Company's long-term debt agreements, approximately $2,815,000 in
principal payments are due over the next twelve months.  The Company believes
its line of credit facility, combined with cash generated from operations, will
be adequate to fund its operations for at least the next twelve months.

                                       15

The Company currently anticipates incurring capital expenditures of
approximately $642,000, principally for machinery and equipment, plant
improvements and vehicle purchases, through the fiscal year ending December 31,
1996.  The Company expects to fund these expenditures from amounts available
under the line of credit facility, cash provided by operations and/or capital
lease transactions.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Shareholders and
Board of Directors of
ERC Industries, Inc.

We have audited the accompanying balance sheet of ERC Industries, Inc. as of
December 31, 1995 and 1994, and the related statements of operations,
shareholders' equity, and cash flows for the two years ended December 31, 1995
and the eleven month period ended December 31, 1993, and the related financial
statement schedule.  These financial statements and the financial statement
schedule are the responsibility of the Company's management.  Our responsibility
is to express an opinion on these financial statements and the financial
statement schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of ERC Industries, Inc. as of
December 31, 1995 and 1994, and the results of its operations and its cash flows
for the two years ended December 31, 1995 and the eleven month period ended
December 31, 1993, in conformity with generally accepted accounting principles.
In addition, in our opinion, the financial statement schedule referred to above,
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.

                         NOTES TO FINANCIAL STATEMENTS


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   NATURE OF OPERATIONS

   The financial statements include the accounts of  ERC Industries, Inc., an
   oilfield services company engaged in the manufacture, remanufacture and
   servicing of oilfield valves and wellhead equipment.  To a lessor extent, it
   also serves the geothermal valve market through its Barton Wood division.
   The Company primarily sells its products to customers in the oil and gas
   production industry located in the major oil and gas producing regions of the
   United States.  The Company intends to expand sales to international oil and
   gas producing regions.

   As of December 31, 1995, approximately 47% of the outstanding shares of ERC
   Industries, Inc.'s (the "Company") common stock was owned by John Wood Group
   PLC ("Wood Group"), a corporation registered in Scotland and incorporated
   under the laws of the United Kingdom. The Wood Group acquired an additional
   11% of the Company's stock subsequent to December 31, 1995.


   CASH AND CASH EQUIVALENTS

   Cash equivalents include highly liquid investments purchased with maturities
   of three months or less at the date of acquisition.  Cash equivalents are
   stated at cost which approximates market because of their short maturity.

 
   INVENTORY

   Inventory consists primarily of finished and semi-finished goods which are
   carried at the lower of cost (specific identification or standard cost which
   approximates FIFO) or market.


   PROPERTY, PLANT AND EQUIPMENT

   Property, plant and equipment are recorded at cost.  Depreciation is provided
   using the straight-line method over the estimated useful lives of the various
   classes of assets which ranges from 3 to 25 years.  Major renewals and
   betterments which extend the lives of equipment are capitalized while all
   other repairs and maintenance are charged to operations as incurred.
   Disposals are removed at cost less accumulated depreciation with any
   resulting gain or loss reflected in income.

                                      F-6
<PAGE>
 
   EXCESS COST OVER NET ASSETS ACQUIRED

   Excess cost over net assets acquired is carried at cost and is amortized
   using the straight-line method over the estimated useful life of 10 years.
   Accumulated amortization, as of December 31, 1995, amounted to approximately
   $458,000.  Periodically, the Company's management assesses recorded balances
   of excess cost over net assets of businesses acquired, for impairment in
   light of historic and projected operating results, trends and profitability,
   new product development and general economic conditions.  Should management
   adversely change its estimate as to recoverability of this asset from future
   operating cash flow, it would be reasonably possible that the carrying amount
   of this asset would change in the near term.

   During 1995, the Company adopted Statement of Financial Accounting Standard
   ("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets and for
   Long-Lived Assets To Be Disposed Of."  SFAS No. 121 addresses the accounting
   for the impairment of long-lived assets, such as property, plant and
   equipment, identifiable intangibles including patents and trademarks, and
   goodwill related to those assets.  In accordance with that standard, the
   Company estimates the future cash flows resulting from the use of that asset
   and its eventual disposition.  If the sum of the expected future cash flows
   is less than the carrying value of the asset, and impairment loss is
   recognized.  The impairment loss is measured as the amount by which the
   carrying amount exceeds the fair value of the asset as determined by quoted
   market prices when available, or the present value of the expected future
   cash flows.  Adoption of SFAS No. 121 has had no impact on net income of the
   Company in 1995.


   INCOME TAXES

   The Company records deferred income tax liabilities and assets for the
   expected future tax consequences of events that have been included in the
   financial statements or tax returns. Under this method, deferred tax
   liabilities and assets are determined based on the difference between the
   financial statement carrying amounts and tax basis of assets and liabilities
   using enacted tax rates in effect in the years in which the differences are
   expected to reverse.


   EARNINGS PER COMMON SHARE

   Primary earnings per common share is based on the weighted average number of
   shares outstanding during the year.

                                      F-7
<PAGE>
 
   CONCENTRATION OF CREDIT RISK

   Financial instruments that potentially subject the Company to concentrations
   of credit risk consist principally of cash and cash equivalents and trade
   accounts receivable.  The Company maintains cash deposits with several major
   banks, which from time-to-time, may exceed federally insured limits.
   Management periodically assesses the financial condition of the institutions
   and believes that any possible credit risk is minimal.  The Company generally
   sells its products to customers in the oil and gas production industry
   located in the major oil and gas producing regions of the United States.
   Procedures are in effect to monitor the credit worthiness of customers and
   bad debts have not been significant in relation to the volume of revenues.
   The Company does not obtain collateral for accounts receivable.


   ESTIMATES AND ASSUMPTIONS

   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.


   RECLASSIFICATIONS

   Certain amounts included in the prior year financial statements have been
   reclassified to conform with current year presentation.

</TABLE>

   The aggregate maturities of long-term debt, including obligations under
   capital leases during the five years subsequent to December 31, 1995 are
   $2,815,000, $287,400, $250,000, $250,000 and $250,000, respectively.

   In connection with the Barton Wood acquisition, the Company entered into a
   10-year $2,500,000 note payable with one of the Barton secured lenders.  At
   December 31, 1995, the

                                      F-9
<PAGE>
 
   note required 32 remaining quarterly installments of $62,500, plus interest
   at the bank's prime rate (8.25% at December 31, 1995), payable each February,
   May, August and November 16. The note is collateralized by specified general
   intangibles and proprietary rights (including certain patents and
   trademarks).  The note also contains certain covenants, the most restrictive
   of which are contained in the Company's line of credit agreement through the
   cross-default provisions of this installment note payable.

   The Company's present line of credit loan facility, which expires June 30,
   1996, provides for maximum borrowings of the lesser of $4,000,000 or eligible
   trade accounts receivable and inventory (as defined in the loan facility).
   Interest on outstanding balances are payable monthly at the bank's prime rate
   minus one-half percent.  At December 31, 1995 the bank's prime rate was 8.5%.
   The facility is collateralized by trade accounts receivable and inventory.
   Additionally, the terms of the facility restrict the Company from paying cash
   dividends and require that the Company maintain a ratio of debt to total net
   worth of not more than 1.2 to 1. At December 31, 1995, amounts outstanding
   under this loan facility were $2,425,000.  In addition, the Company had
   outstanding, against the revolving line of credit facility, irrevocable
   letters of credit amounting to approximately $175,000.  At December 31, 1995,
   the Company's maximum amount available for additional borrowings was
   $1,400,000.


5. INCOME TAXES

   The Company records deferred income tax liabilities or assets for the net tax
   effects of temporary differences between the carrying amounts of assets and
   liabilities for financial reporting purposes and the amounts used for income
   tax purposes.  Significant components of the Company's deferred tax
   liabilities and assets are as follows:

</TABLE>

   The valuation allowance was increased during 1995 by $169,000.  At December
   31, 1995, the Company had federal net operating loss (NOL) carryforwards
   available to offset future taxable income in the approximate amount of
   $26,444,000.  Of these NOL carryforwards,

                                      F-10
<PAGE>
 
   approximately $23,800,000 expire between the years 2001 and 2003 with the
   balance expiring in 2009.  Special limitations exist under the law which may
   restrict the utilization of the net loss carryforwards, including the
   alternative minimum tax.

   The Company has recorded a net deferred tax asset of $548,000 reflecting the
   benefit of approximately $1,612,000 in temporary differences which will
   provide tax deductions on future income tax returns.  Realization of these
   assets is dependent on generating sufficient taxable income in the future to
   offset these tax deductions.  Although realization is not assured, management
   believes it is more likely than not that all of the deferred tax asset will
   be realized.  The amount of the deferred tax asset considered realizable,
   however, could be reduced in the near term if estimates of future taxable
   income are reduced.

   The following is a summary of the provision for income taxes:

   The non-cash charges in lieu of income taxes represents the amount of income
   taxes the Company would pay absent the NOL carryforwards which was generated
   before the Company affected a quasi-reorganization.  Such charges are offset
   within shareholders' equity by an increase in additional paid-in capital.

   The reconciliation between the actual (benefit)/provision recorded for income
   taxes and the (benefit)/provision for income taxes at the United States
   federal statutory rate for the years ended December 31, 1995 and 1994, and

6. RELATED PARTY TRANSACTIONS

   The Company and Wood Group have agreed to an annual provision for
   administrative and financial services fees in amounts to be determined on an
   annual basis.  The Company paid or accrued $173,000 and $155,000 for the
   years ended December 31, 1995 and 1994, respectively, and $96,000 in such
   fees for the eleven months ended December 31, 1993.

7. COMMITMENTS AND CONTINGENCIES

   The Company leases office space and various equipment under noncancelable
   operating leases expiring through the year 2000.  The leases provide for
   minimum monthly payments, plus in certain instances, payment for taxes,
   insurance and maintenance.  Certain leases also contain renewal options.  The
   Company is liable under noncancelable leases for minimum lease commitment
   amounts during the five years subsequent to December 31, 1995 as follows:
   $321,000, $295,000, $105,000, $30,000, and $30,000 respectively.

   Rental expenses for the years ended December 31, 1995 and 1994 and the eleven
   months ended December 31, 1993, were $447,000, $405,000, and $186,000,
   respectively.

   In connection with the Barton Wood acquisition in late 1993, the Company
   leased, and has an option to purchase, certain real property and equipment
   from the Barton secured lenders ("lessors") at any time during the term of
   the leases, which extend through February, 1998. In the event the Company
   does not exercise its option, it will be required to pay $150,000 to the
   lessors of the real property.  This obligation is collateralized by a
   commercial bank letter of credit issued for the benefit of the lessor, which
   is renewed annually.  Similarly, should the Company not exercise its option
   to buy the leased equipment, it will be required to pay $125,000 to the
   lessor.  Subsequent to year end, management decided not to exercise its
   option to buy the leased equipment.

   Effective January 1, 1994, the Company has authorized a long-term incentive
   program for its key employees.  The incentive payments will be based on the
   improvement in pre-tax earnings per share over a stated amount.  The program
   has been implemented, but had no impact on operations during 1995 and 1994.


8. PROFIT SHARING AND 401(K) PLANS

   The Company has a defined contribution 401(k) profit sharing plan.  The plan
   covers substantially all employees subject to certain length of service
   requirements.  Contributions are made at the discretion of the Board of
   Directors. The Company paid $49,000 during 1994 for contributions accrued at
   December 31, 1993. The Company paid $27,000 during 1995 for contributions
   accrued at December 31, 1994.  No contributions will be paid or accrued for
   the year ended December 31, 1995.

   during the 1995 and 1994 fiscal years.  The Company had one customer who
   accounted for approximately 10% of the total revenues for the eleven month
   period ended December 31, 1993.

                     SEVENTH AMENDMENT TO CREDIT AGREEMENT
                             (WITH BORROWING BASE)

July 3, 1995, (the "Effective Date") is by and between ERC INDUSTRIES, INC.
("Borrower"), and TEXAS COMMERCE BANK NATIONAL ASSOCIATION, a national banking

3.  The Borrower hereby represents and warrants to the Bank that after giving
    effect to the execution and delivery of this Amendment: (a) the
    representations and warranties set forth in the Credit Agreement are true
    and correct on the date hereof as though made on and as of such date; and
    (b) no Event of Default, or event which with passage of time, the giving of
    notice or both would become an Event of Default, has occurred and is

5.  Borrower further acknowledges that each of the other Loan Documents are in
    all respects ratified and confirmed, and all of the rights, powers and
    privileges created thereby or thereunder are ratified, confirmed, extended,
    carried forward and remain in full force and effect except as the Credit
    Agreement is amended by this Amendment.

6.  This Amendment may be executed in any number of counterparts and by
    different parties hereto in separate counterparts, each of which when so
    executed shall be deemed an original and all of which taken together shall
    constitute but one and the same agreement.

7.  THIS AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
    LAWS OF THE STATE OF TEXAS AND AS APPLICABLE, THE LAWS OF THE UNITED STATES

                                       2
<PAGE>
 
    Credit Agreement and "Agreement", as used in the Credit Agreement, shall
    mean the Credit Agreement as amended by this Amendment.

9.  WAIVER AGREEMENT. Pursuant to Section 5.2 of the Agreement, Borrower agreed
    to comply with and maintain the financial covenants set forth on Annex III
    of the Credit Agreement, including maintaining a maximum Debt to Net Worth
    ratio of not more than 1.0 : 1.0. Borrower has informed Bank that Borrower
    is out of compliance with this covenant for the periods ended June 30, 1995
    through October 31, 1995. Although Borrower is in default under the Credit
    Agreement because of the failure to comply with the above-referenced
    covenant as required, Bank is electing to waive this specific default but
    only for the time period ended June 30, 1995 through October 31, 1995. This
    waiver does not constitute a waiver of any other defaults that may currently
    exist or that may hereafter occur, including but not limited to the above
    cited Section of the Agreement. Bank's delay in exercising any of its rights
    under the Credit Agreement does not constitute a waiver of any rights or
    interests of Bank except as specifically agreed to in writing by Bank. This
    Section is not a general waiver of the above-referenced covenant or any
    other requirements contained in this Agreement or any other Loan Document.
    In the past Bank may have made advances under the Commitment at times when
    Borrower did not satisfy all of the conditions precedent to advances and/or
    because Borrower was in default under the Credit Agreement. Bank has the
    right to refuse to fund an advance at any time that Borrower is not in
    compliance with the terms of the Agreement. If Bank elects to make any
    advance to Borrower while Borrower is out of compliance with the Agreement,
    the making of such advances shall not constitute a waiver of any defaults
    then existing or thereafter arising under the Agreement, and will not
    constitute the agreement of Bank to make further advances in similar
    circumstances. This Section constitutes the only evidence of Bank's waiver
    of compliance with the above cited Section of the Credit Agreement.

THIS WRITTEN AMENDMENT AND THE OTHER LOAN DOCUMENTS CONSTITUTE A "LOAN DOCUMENT"
AS DEFINED IN SECTION 26.02(A) OF THE TEXAS BUSINESS & COMMERCE CODE, AND
REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     THIS TENTH AMENDMENT TO CREDIT AGREEMENT (this "Amendment" or "Tenth
Amendment") dated as of April 1, 1996, ("Effective Date") is between ERC
INDUSTRIES, INC. ("Borrower"), and TEXAS COMMERCE BANK NATIONAL ASSOCIATION, a
national banking association ("Bank").

PRELIMINARY STATEMENT.  Bank and Borrower have entered into a Credit Agreement
(Borrowing Base), dated February 25, 1991, amended by a First Amendment dated
August 31, 1991, Second Amendment dated January 3, 1992, Third Amendment dated
May 31, 1992, Fourth Amendment dated December 30, 1992, Fifth Amendment dated
February 28, 1994, Sixth Amendment dated February 27, 1995, Seventh Amendment
dated July 3, 1995, Eighth Amendment dated December 7, 1995 and Ninth Amendment
dated February 26, 1996 (as amended, "Credit Agreement" or "Agreement).  All
defined terms and section, exhibit and annex references shall refer to the
Credit Agreement as amended. The Bank and the Borrower have agreed to amend the
Credit Agreement to the extent set forth herein, and in order to, among other
things, renew, extend and modify the Commitment and the Commitment 2.

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

1.  Subsection 1.1.A is amended to read as follows:

    "REVOLVING CREDIT NOTE 1.1.A. Subject to the terns and conditions hereof,
    Bank agrees to make loans to Borrower from time to time before the
    Termination Date, not to exceed at any one time outstanding the lesser of
    the Borrowing Base or $3,000,000.00 ("Commitment"). Loans shall take the
    form of advances under the note (as hereinafter defined) (each a "Loan"), or
    issuances by Bank of commercial letters of credit ("Commercial L/Cs") and/or
    standby letters of credit ("Standby L/Cs") (collectively, "Letters of
    Credit"). Borrower shall have the right to borrow, repay and reborrow under
    the note. Bank and Borrower agree that Chapter 15 of the Texas Credit Code
    shall not apply to this Agreement, the Note, or any Loan. Loans shall be
    evidenced by and shall bear interest and be payable as provided in
    Borrower's $3,000,000.00 promissory note dated the Tenth Amendment Effective
    Date (together with any and all renewals, extensions, modifications
    replacements, and rearrangements thereof and substitutions therefor,
    "Note"), given in renewal and modification of Borrower's $3,000,000.00
    promissory note dated February 26, 1996 (including all prior notes of which
    said note represents a renewal, extension, modification, increase, decrease,
    substitution, rearrangement or replacement thereof, a "Renewed Note"). As of
    March 27, 1996 there was an outstanding principal

                                       1

    balance of $2,800,000.00 under the Commitment, and an aggregate of
    $178,682.08 in L/C Obligations (representing Letter of Credit numbers
    1460191, 1451961, 1444134, 1455643 and 1456977 issued and outstanding as of
    such date) for a total outstanding against the Commitment of $2,978,682.08;
    leaving $21,317.92 available under the Commitment on such date for
    additional Loans and issuances of Letters of Credit subject to the terms and
    conditions of this Agreement. Loans and Letters of Credit under the
    Commitment shall be for the purpose of providing working capital and letters
    of credit for Borrower's regular business operations."

2.  Subsection 1.1.C is amended to read as follows:

    "REVOLVING CREDIT NOTE-2 1.1.C. Subject to the terms and conditions hereof
    the Bank agrees to make loans ("Loans 2") to the Borrower from time to time
    before June 30, 1996 not to exceed at any one time outstanding the lesser of
    the Borrowing Base or $1,000,000.00 ("Commitment 2"), Borrower having the
    right to borrow, repay and reborrow. Bank and Borrower agree that Chapter 15
    of the Texas Credit Code shall not apply to this Agreement, Note 2 (as
    hereinafter defined) or any Loan 2. Loans 2 shall be evidenced by and shall
    bear interest and be payable as provided in Borrower's $1,000,000.00
    promissory note dated the Tenth Amendment Effective Date (together with any
    and all renewals, extensions, modifications and replacements thereof and
    substitutions therefor, the "Note 2"), given in renewal and modification of
    Borrower's $1,000,000.00 promissory note dated July 3, 1995 (including all
    prior notes of which said note represents a renewal, extension,
    modification, increase, decrease, substitution, rearrangement or replacement
    thereof, a "Renewed Note"). As of March 27, 1996 there was an outstanding
    principal balance of $300,000.00 under the Commitment-2, leaving $700,000.00
    available under Commitment-2 for additional Loans 2 subject to the terms and
    conditions of this Agreement. Loans 2 shall be for the purpose of providing
    working capital for Borrower's regular business operations."

3.  Section 8.  The definition of Termination Date is amended by substituting
    "June 30, 1996" in place of "April 1, 1996", where the latter appears.

4.  Exhibit A is replaced with Exhibit A attached hereto.

    other interests granted to Bank in each and all security agreements executed
    in connection with, related to, or securing each Renewed Note, L/C
