                                  THE COMPANY

     The Company is a diversified engineering company providing engineering
services and engineered systems to a broad range of industrial, commercial and
institutional clients throughout the United States and internationally. The
Company's multidisciplined expertise enables it to offer its clients total
design and engineering solutions extending from project inception through
completion, start-up and operation, within multiple industries and across
diverse geographic markets. During 1997, the Company was involved in engineering
projects in 26 states and over 21 countries worldwide, generating pro forma
combined revenues of approximately $169.1 million, of which $119.5 million, or
70.7%, was from domestic projects, and $49.6 million, or 29.3%, was from
international work.

     OEI was formed in October 1997 by Petrocon's management to conduct the
Offering, simultaneously consummate the Pending Acquisitions and continue
Petrocon's successful acquisition program. The Company, through Petrocon, has
grown significantly through acquisitions, having acquired more than 13
engineering firms since 1988. As a result of the Pending Acquisitions and the
Offering, the Company believes it will have greater financial, technical and
professional resources, which will enable it to aggressively continue its
successful acquisition strategy, enhance its technical capabilities and expand
its already diversified client base.

     The Company operates in two principal segments: engineering services and
engineered systems. The Company's engineering services encompass all aspects of
the process, civil, structural, mechanical, instrument, electrical, geotechnical
and environmental engineering and design disciplines, providing its clients with
a single source for all their design, engineering and permitting needs. The
Company has designed and engineered facilities ranging from refineries,
petrochemical plants, pulp and paper processing plants and wastewater treatment
facilities, to food and beverage processing plants, pharmaceutical plants and
laboratories, electronics manufacturing facilities, hotels and casinos. The
Company's engineered systems are primarily custom designed, built, programmed
and installed on a fixed-price, turnkey basis and include control and
instrumentation systems and modular processing plants primarily for the oil and
gas, refining and chemical processing industries. During 1997, approximately
$124.5 million, or 73.6%, of the Company's pro forma combined revenues were
attributable to engineering services and $44.6 million, or 26.4%, were
attributable to engineered systems. The Company provides engineering services
and engineered systems to a number of Fortune 100 companies through a staff of
over 1,600 employees, including approximately 1,100 engineers and design
professionals as of December 31, 1997.

     The Company has developed a strategic plan to:

            o   EXPAND AND DIVERSIFY THROUGH ACQUISITIONS.  By continuing to
     acquire well-established and highly respected local and regional firms
     within the U.S., as well as foreign firms, the Company intends to (i)
     expand into new geographic markets, (ii) broaden its areas of acknowledged
     technical

                                       3
<PAGE>
     expertise, (iii) continue to strengthen its presence within existing
     geographic markets and specialties and (iv) enhance its cross-marketing
     opportunities.

            o   ACCELERATE INTERNAL GROWTH.  The principal elements of the
     Company's internal growth strategy are to (i) attract larger, higher margin
     projects, (ii) leverage the Company's capabilities and expertise through
     cross-marketing and (iii) develop partnering relationships and other
     strategic alliances.

            o   IMPROVE OPERATING MARGINS.  The Company intends to capitalize on
     opportunities to achieve operating efficiencies and cost savings by
     implementing strategies to (i) increase its overall staff utilization rate
     by more effectively deploying and allocating its professional resources,
     (ii) consolidate administrative functions and (iii) use its increased
     purchasing power to gain volume discounts for itself and in connection with
     its procurement services for its clients.

            o   OUTSOURCE CONSTRUCTION ACTIVITIES.  The Company believes it can
     offer clients the advantages of turnkey, lump sum projects, without
     directly performing the construction activities associated with these
     projects, by forming joint ventures and other partnering relationships with
     construction firms. The Company believes it will benefit from such a
     strategy by limiting its exposure to construction risks.

            o   OPERATE ON A DECENTRALIZED BASIS.  The Company intends to manage
     its operating companies on a decentralized basis, with local management
     retaining responsibility for day-to-day operations, profitability and
     growth. The Company believes that combining a decentralized management
     structure with strong, centralized operating and financial controls geared
     to accountability, will support the entrepreneurial and creative culture at
     each of the operating companies, while allowing the Company to capitalize
     on the local and regional market knowledge, goodwill, name recognition and
     client relationships of each of the operating companies.

     In recent years, the Company has observed and benefitted from a growing
demand for its services and systems due to, among other reasons, (i) an industry
trend towards outsourcing engineering functions as a result of reduced in-house
engineering staffs, (ii) rapid technological advancements in construction,
manufacturing and processing operations, (iii) the increased scope and
complexity of governmental, and particularly environmental, regulations and (iv)
increased capital expenditures resulting from aging infrastructures of the
United States and Western Europe, as well as the rapid growth and
industrialization of the lesser developed countries. According to ENGINEERING
NEWS-RECORD ("ENR"), its "Top 500 Design Firms," which include U.S.-based
engineer-constructor, engineer-architect and other hybrid organizations, as well
as exclusively design and planning firms, billed their clients an aggregate
$    billion in 1997. ENR also reports that the world's "Top 200 International
Design Firms" had worldwide revenues aggregating more than $    billion in
1997. Industry consultants estimate there are more than 28,000 engineering firms
in the U.S. alone, and the Company believes there are significant opportunities
for an established, professionally managed and well-capitalized engineering
company to consolidate regional, local and foreign engineering firms.

     The Company's executive offices are located at 2727 North Loop West, Suite
400, Houston, Texas 77009, and its telephone number is (713) 880-6200.

                                  RISK FACTORS

     Prior to making an investment decision, prospective purchasers of the
Common Stock offered hereby should consider carefully all of the information set
forth in this Prospectus and, particularly, should evaluate the following risk
factors.

LIMITED COMBINED OPERATING HISTORY; RISKS RELATED TO INTEGRATION AND INTERNAL
GROWTH

     Petrocon and the Acquired Companies have operated, and will continue to
operate prior to the closing of the Pending Acquisitions, as separate,
independent businesses. Consequently, the pro forma financial information
contained herein may not be indicative of the Company's future operating results
and financial condition. The Company will rely initially on the separate
accounting and information systems of Petrocon and each of the Acquired
Companies, but the success of the Company will depend, in part, on the extent to
which it is able to centralize and integrate necessary systems and functions,
including accounting, financial reporting and job costing systems, among the
Acquired Companies. The inability of the Company to successfully centralize and
integrate these systems and functions could have a material adverse effect on
the Company's business, financial condition and results of operations, and could
adversely affect the Company's implementation of its acquisition and operating
strategies. See "Business -- Operations."

     The success of the Company's internal growth strategy will depend on
various factors, including the demand for the Company's services and systems and
the Company's ability to (i) attract larger, higher margin projects, (ii)
leverage its capabilities and expertise through cross-marketing, (iii) develop
partnering relationships and other strategic alliances and (iv) achieve client
acceptance of project processes through which the Company intends to share work,
professionals and other resources among its operating companies. These factors
are, at least in part, beyond the Company's control, and there can be no
assurance the Company's internal growth strategy will be successful.

DEPENDENCE ON INDUSTRY SPENDING

     The demand for the Company's services and systems depends on the level of
capital and maintenance expenditures by its industrial, commercial and
institutional clients, particularly those private sector clients involved in the
oil and gas, refining and petrochemical industries. In 1997, the revenues
attributable to the oil and gas, refining and petrochemical industries
represented $141.2 million, or 83.5% of the Company's pro forma combined
revenues. These industries historically have been cyclical in nature and
vulnerable to many of the same national and regional economic factors that
affect the economy in general. In addition, if the current or any future decline
in energy prices were to be sustained over a significant period of time, the
capital and maintenance expenditures within these industries may be adversely
affected, which could have a material adverse effect on the Company's operating
results. Other factors influencing private and public spending levels include
general economic conditions, inflation, interest rates, the availability of
financing, the availability and price of raw materials, and political
considerations.

DEPENDENCE ON LARGE PROJECTS

     The Company historically has not had a continuing dependence on any single
client or a limited group of clients; however, one or a few clients have
contributed in the past, and may in the future contribute, a substantial portion
of the Company's revenues in any one year or over a period of several
consecutive years due to the size of particular engineering projects. In 1997,
the Company's five largest projects represented $14.4 million, or 8.5%, of the
Company's pro forma combined revenues. Accordingly, the Company must continually
obtain significant new engineering projects, whether from existing or new
clients, in order to generate revenues in the future as existing projects are
completed. The failure to do so would have a material adverse effect on the
Company's operating results. See "Business -- Clients."

FOREIGN OPERATIONS

     In 1997, the Company derived approximately $49.6 million, or approximately
29.3%, of its pro forma combined revenues from foreign projects. Also, Petrocon
Arabia Limited ("PAL"), in which the Company has a 50% interest, had 1997
revenues of approximately $16.5 million, which are not included in the

                                       8
<PAGE>
Company's 1997 pro forma combined revenues because the Company accounts for its
interest in PAL by the equity method. Most of PAL's revenues were derived from
work in the Middle East. International engineering and design work involves
risks that are normally associated with doing business overseas, such as risks
of war, terrorism, expropriation, civil unrest, political and economic
instability, nationalization of assets, currency fluctuation and repatriation
risks, overlap of different tax structures and sometimes ill-defined or
underdeveloped systems of contract laws and commercial codes. Additionally,
certain international risks are particular to engineering and construction,
including (i) open-ended bonds or other security instruments to guarantee bids
and performance, (ii) reliance on host country subcontractors, suppliers and
personnel, (iii) permitting, construction and payment delays occasioned by
bureaucratic inefficiencies, and (iv) difficulties in obtaining required or
appropriate insurance. See "Business -- Foreign Operations."

DEPENDENCE ON ACQUISITIONS FOR GROWTH

     The Company intends to grow primarily by acquiring engineering and design
firms which expand or complement the Company's existing operations. The
Company's acquisition strategy presents risks that, singly or in combination,
could materially adversely affect its business and financial performance. These
risks include those inherent in assessing the value, strengths, weaknesses,
contingent or other liabilities and potential profitability of acquisition
candidates, the possibility of an adverse effect on existing operations of the
Company from the diversion of management attention and resources to
acquisitions, and the possible loss of acquired client bases and key personnel,
including engineers, designers, scientists and other professionals. The success
of the Company's acquisition strategy will depend on the extent to which
acquisition candidates continue to be available and whether the Company will be
able to acquire, successfully integrate and profitably manage additional
businesses. The Company believes that competitive and other pressures are
causing engineering firms of all sizes to combine at the local, regional,
national and international levels. Therefore, competition for acquisition
candidates could materially increase their cost. The timing, size and success of
the Company's acquisition efforts, and the associated capital commitments,
cannot readily be predicted. Accordingly, no assurance can be given the
Company's acquisition strategy will succeed. See "Business -- Business
Strategy" and "Business -- Acquisition Strategy."

NEED FOR ADDITIONAL FINANCING

     All of the net proceeds of the Offering will be used in connection with the
Pending Acquisitions. See "Use of Proceeds." The Company's acquisition
strategy will require substantial additional capital. The Company currently
intends to use cash and shares of Common Stock in making future acquisitions.
Using internally generated cash or debt to complete acquisitions could
substantially limit the Company's operational and financial flexibility. The
extent to which the Company will be able or willing to use Common Stock for
acquisitions will depend on the market value of the Common Stock from time to
time and the willingness of potential sellers to accept the Common Stock as full
or partial payment. Using Common Stock for acquisitions may result in a
significant dilution to then existing Company stockholders. To the extent the
Company is unable to use Common Stock to make future acquisitions, its growth
may be limited by its ability to raise capital for this purpose through debt or
additional equity financings. The Company cannot assure that it will be able to
obtain the necessary capital to finance a successful acquisition program while
meeting its other cash needs. If the Company is unable to obtain additional
capital on acceptable terms, it may be required to reduce the scope of its
presently anticipated expansion. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Pro Forma Combined -- Liquidity
and Capital Resources."

     The Company has recently received a commitment letter from
                           to provide the Company with a $     million credit
facility (the "New Credit Facility"), which may be used for refinancing of
certain indebtedness of the Company, acquisitions, working capital and other
general corporate purposes. The Company expects the New Credit Facility will
require compliance with various affirmative and negative covenants (including
maintenance of certain financial ratios) which could limit the Company's
operational and financial flexibility. The New Credit Facility is subject to
negotiation of definitive documentation and certain other customary conditions,
and there can be no assurance that the

                                       9
<PAGE>
Company will be able to obtain the New Credit Facility on terms acceptable to
the Company. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Pro Forma Combined -- Liquidity and Capital
Resources."

PRICING AND RELATED RISK SHARING

     Historically, a high percentage of the Company's projects have been
undertaken on a relatively riskless cost plus fee (either fixed or a percentage)
basis. However, project owners are increasingly seeking, and the Company and its
competitors are accepting and even initiating, pricing alternatives designed to
shift to the service provider, or requiring the service provider to at least
share in, the risks of cost overruns and inefficiencies in the delivery of
services. These alternatives include fixed-price, guaranteed maximum price,
incentive fee, competitive bidding and other "value based" pricing
arrangements. The Company expects this trend to continue in the future, with the
result that the Company will be required to maintain and continually improve,
relative to its competitors, both the precision of its cost estimates and the
efficiency with which it delivers its services. If the Company's discipline in
either of these areas declines or fails to keep pace with that of its
competitors, both the volume of awarded projects and their margins may be
affected adversely. See "-- Competition," "Business -- Contracts" and
"Business -- Competition."

COMPETITION

     The Company competes nationally and internationally with many engineering
and construction management firms that are substantially larger and have
substantially greater financial, professional and other resources than the
Company. The Company also faces competition from many regional and local firms.
Barriers to entry for engineering firms are relatively low, and the risk of new
competitors entering the market, particularly in local and regional areas, and
particularly with respect to speciality areas, is high. See
"Business -- Competition."

NATURE OF BACKLOG

     At December 31, 1997, the Company's combined backlog was $100.5 million
compared to $63.3 million at December 31, 1996. The combined backlog, most of
which is expected to be completed within the next 12 months, includes only
contracts for which the Company has received authorization to proceed with the
work. Although this backlog represents only work which is under contract, it is
not necessarily indicative of the Company's future revenues or earnings related
to the performance of the work included in backlog. The Company's contracts are
subject to standard industry cancellation provisions, including cancellation on
short notice or upon completion of designated stages. Authorizations to proceed
are for periods generally shorter than the duration of the work the Company
expects to perform for a particular client, and substantial scope-of-work
adjustments are common. For these and other reasons beyond the Company's
control, work represented in backlog may be delayed or cancelled, and backlog
should not be relied upon as an indicator of the Company's future performance.
See "Business -- Backlog."

COMPLETION GUARANTEES

     In certain instances, the Company guarantees project completion by a
scheduled date or by achievement of certain acceptance and performance testing
or milestone levels. At December 31, 1997, the Company had underway projects
aggregating approximately $46.9 million in contract amount, which are subject to
some form of completion or performance guarantee. If the Company fails to meet
any required completion or performance requirement and is unable to remedy the
failure within any applicable cure period, the Company could incur financial
penalties in the form of liquidated damages or could be required to redesign or
repeat the service or replace or repair the system. While the Company has in the
past undertaken a limited number of guaranteed projects and has not incurred
material obligations with respect to such projects, the Company may in the
future undertake more guaranteed projects, which could have a material adverse
effect on the Company if it is unable to satisfy future guarantee requirements.

                                       10
<PAGE>
RELIANCE ON SKILLED PROFESSIONALS AND MANAGEMENT PERSONNEL

     The Company derives its revenues from, and its reputation is based on, the
efforts of engineers, scientists, chemists, designers and other highly skilled
and experienced technical personnel. Demand for these professionals is high,
their qualifications render them particularly mobile, and they are particularly
attentive to their workplace environment. The on-going risk of losing qualified
and experienced professionals from the Company could increase because of actual
or perceived changes resulting from becoming part of a larger and perhaps
culturally different organization. The business of the Company could be affected
adversely if the Company's ability to retain skilled professionals becomes
impaired for any reason.

     The Company also depends in large part on the continuing efforts of its
executive officers and senior management, and will likely depend on the senior
management of any significant business it acquires in the future. That
dependence may be intensified by the Company's decentralized operating strategy.
If members of senior management leave the Company, until the Company attracts
and retains qualified replacements, the Company's business or prospects could be
affected adversely. Further, the historical growth of the Company can in some
measure be attributed to the entrepreneurial spirit of its senior management. To
the extent the circumstances of the Pending Acquisitions are perceived by
certain members of senior management as an impediment to this entrepreneurial
attitude, the impetus for the Company's continued growth following the Pending
Acquisitions could diminish.

PROCEEDS OF OFFERING PAYABLE TO AFFILIATES AND ASSOCIATES

     The net proceeds from the Offering will be used: (i) to pay the cash
portion of the aggregate purchase price for the Pending Acquisitions
(approximately $27.8 million); (ii) to repay certain outstanding indebtedness of
the Company (approximately $21.8 million); (iii) to place in escrow
approximately $3.4 million, which will be subject to a maximum three year
earnout arrangement with respect to one of the Pending Acquisitions; and (iv) to
pay certain expenses of the Offering and the Pending Acquisitions. See "Use of
Proceeds." The cash payable to the former stockholders of Petrocon and the
Acquired Companies will include approximately $2.7 million payable to persons
who will become directors or executive officers of OEI. The Offering will enable
the Company to repay $2.5 million of advances by Equus II Incorporated ("Equus
II"), which were used to pay expenses of the Offering, and will benefit the
existing stockholders of the Company by creating a public market for the Common
Stock. For a more detailed discussion of the use of proceeds of the Offering,
and the benefits to be received by persons who are or will become directors or
executive officers of OEI or beneficial holders of 5% or more of the Common
Stock on consummation of the Offering and the Pending Acquisitions, see "Use of
Proceeds" and "Certain Transactions -- Pending Acquisitions Involving Certain
Officers, Directors and Stockholders."

LIABILITY CLAIMS AND INSURANCE

     Providing engineering and design services involves the risk of contract,
professional errors and omissions and other liability claims, as well as adverse
publicity. Further, many of the Company's contracts with its clients require the
Company to indemnify the clients not only for the Company's negligence, but also
for the concurrent negligence of the clients. While the Company maintains
liability insurance coverage, including for professional errors and omissions,
in amounts it considers adequate, there can be no assurance that claims outside
of or exceeding its insurance coverage will not be made, or that the Company
will be able to continue to obtain adequate insurance coverage at rates it
considers reasonable. See "Business -- Risk Management; Litigation."

SEASONALITY

     Holidays and inclement weather during the Company's fourth quarter exert
downward pressure on the Company's revenues for that quarter, which is only
partially offset by the year-end efforts on the part of many of the Company's
clients, particularly in the energy and public sectors, to spend any remaining
funds budgeted for capital expenditures during the year. The annual budgeting
and approval process under which these clients operate is normally not completed
until after the beginning of each new year, which, when combined with continuing
inclement weather, can depress the Company's operating results for the first

                                       11
<PAGE>
quarter. Principally due to these factors, the Company's revenues during its
first and fourth quarters tend to be, but are not always, lower than in its
second and third quarters.

GOVERNMENT REGULATION

     The Company and its clients are subject to various foreign, federal, state
and local laws and regulations, including those relating to the environment,
health and safety. To date, the Company has mostly benefited from these laws and
regulations because of their impact on its clients, and the cost of the
Company's own compliance has not been material, but the fact that such laws and
regulations are changed frequently makes uncertain both the Company's future
benefits and costs associated with such laws and regulations. The modification
of existing laws or regulations or the adoption of new laws or regulations
affecting the Company's clients or its own operations or industry could
adversely affect the Company.

SIGNIFICANT INTANGIBLE ASSETS

     As a result of the Pending Acquisitions, goodwill will account for a
material portion of the Company's total assets. On a pro forma combined basis,
goodwill was recorded at approximately $68.4 million at December 31, 1997,
representing approximately 55.2% of the Company's total assets. The Company's
goodwill is to be amortized over a 40-year period resulting in annual non-cash
amortization charges against income of approximately $1.7 million. The Company
may record additional goodwill and related amortization charges in connection
with the implementation of its acquisition strategy. See "-- Dependence on
Acquisitions for Growth."

YEAR 2000 COMPLIANCE

     The Company uses computer software programs and operating systems in its
internal operations, including applications used in financial business systems
and various administration functions, and also utilizes software programs in
providing certain engineering services and engineered systems. To the extent
that these software applications contain code that is unable to appropriately
interpret upcoming calendar year 2000, some level of modification of such source
code or applications will be necessary. The Company is currently in the process
of evaluating its computer software programs and operating systems to ensure
such programs and systems will be able to process transactions in the year 2000.
However, the Company does not believe that the costs to modify its programs or
systems will be material to its financial condition or results of operations.
The Company does not currently have information concerning the year 2000
compliance of its clients and suppliers. The failure of the Company's clients
and suppliers to achieve year 2000 compliance could have a material adverse
effect on the Company's financial condition and results of operations.

SIGNIFICANT VOTING CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS

     Upon closing of the Pending Acquisitions and the Offering, the respective
stockholders of Petrocon and the Acquired Companies, OEI's initial financing
source (Equus II) and the executive officers of OEI (all but one of whom is also
an executive officer of Petrocon), will beneficially own in the aggregate
approximately     % of the outstanding Common Stock. If these persons were to
act in concert, they would be able to exercise control over the Company's
affairs, including the election of the entire Board of Directors and, subject to
Section 203 of the Delaware General Corporation Law (the "DGCL"), any matter
submitted to a vote of stockholders. See "Principal Stockholders."

POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON STOCK

     Upon closing of the Pending Acquisitions and the Offering,
shares of Common Stock will be outstanding. The           shares sold in the
Offering (other than shares purchased by affiliates of the Company) will be
freely tradable. The remaining shares outstanding may be resold publicly only
following their effective registration under the Securities Act of 1933, as
amended (the "Securities Act"), or under an available exemption from the
registration requirements of the Securities Act, such as the exemption provided
by Securities Act Rule 144 promulgated by the Securities and Exchange Commission
(the "SEC"). Under Rule 144, all those remaining shares will be eligible for
Rule 144 sales, subject to certain

                                       12
<PAGE>
volume limitations and other requirements, on the day following the first
anniversary of the date the Offering closes. The holders of a substantial number
of those remaining shares have certain registration rights granted by OEI in
connection with the Pending Acquisitions, subject to a two-year lockup period.

     Upon closing of the Offering, options and warrants to purchase up to a
total of           shares of Common Stock will be outstanding, of which options
and warrants to purchase 566,076 shares will be exercisable immediately after
the closing. The Company intends to register all the shares subject to options
granted under the Incentive Plan and the Company's 1998 Employee Stock Purchase
Plan (the "Employee Purchase Plan") under the Securities Act for public
resale.

     The Company, the OEI directors, executive officers and current stockholders
(including Equus II) and all persons who acquire shares of Common Stock in
connection with the Pending Acquisitions have agreed not to offer, sell or
otherwise dispose of any shares for a period of two years following the date of
this Prospectus without the prior written consent of Smith Barney Inc., except
that the Company may issue, subject to certain conditions, Common Stock in
connection with acquisitions and pursuant to awards under the Incentive Plan and
the Employee Purchase Plan (see "Management -- Incentive Plan").

     The Company intends to register           additional shares of Common Stock
under the Securities Act during 1998, for use in connection with future
acquisitions. These shares generally will be freely tradable after their
issuance by persons not affiliated with the Company, unless the Company is able
to contractually restrict their resale. Sales of these shares during the Lockup
Period would require the prior written consent of Smith Barney, Inc.

     Availability for sale, or sale, of the shares of Common Stock eligible for
future sale could adversely affect the market price of the Common Stock from
time to time. See "Shares Eligible for Future Sale."

IMMEDIATE AND SUBSTANTIAL DILUTION

     Purchasers of Common Stock in the Offering (i) will experience immediate,
substantial dilution in the net tangible book value of their stock of $     per
share and (ii) may experience further dilution in that value from future
issuances of shares of Common Stock. See "Dilution."

NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

     Before the Offering, no public market for the Common Stock has existed, and
the initial public offering price negotiated by the Company and the
representatives of the Underwriters may not be indicative of the price at which
the Common Stock will trade after the Offering. See "Underwriting" for the
factors to be considered in determining the initial public offering price. The
Company has applied for listing of the Common Stock on the New York Stock
Exchange, but no assurance can be given that an active trading market for the
Common Stock will develop or, if it does, that it will continue after the
Offering. The market price of the Common Stock after the Offering may be subject
to significant fluctuations from time to time in response to many factors,
including variations in the reported financial results of the Company and
changing conditions in the economy in general, in the Company's industry in
particular, or in the industry of one of the Company's major client groups. In
addition, the stock markets experience significant price and volume volatility
from time to time which may affect the market price of the Common Stock for
reasons unrelated to the Company or its performance.

POTENTIAL ANTI-TAKEOVER EFFECTS

     OEI's Certificate of Incorporation, as amended (the "Charter"),
authorizes the issuance, without stockholder approval, of one or more series of
preferred stock having such preferences, powers and relative, participating,
optional and other rights (including preferences over the Common Stock
respecting dividends, distributions and voting rights) as the board of directors
of OEI (the "Board of Directors") may determine. See "Description of Capital
Stock -- Preferred Stock."

     Certain provisions of the Charter, OEI's bylaws and the DGCL may delay,
discourage, inhibit, prevent or render more difficult an attempt to obtain
control of the Company, whether by means of a tender offer, business
combination, proxy contest or otherwise. These provisions include the Charter
authorization of

                                       13
<PAGE>
"blank check" preferred stock, classification of the Board of Directors, a
limitation on the removal of directors only for cause, and then only on approval
of holders of two-thirds of the outstanding voting stock, a restriction on the
ability of stockholders to take actions by written consent and a DGCL
restriction on business combinations with certain interested parties. See
"Description of Capital Stock."

FORWARD-LOOKING STATEMENTS

     With the exception of historical information, the matters discussed in this
Prospectus may include forward-looking statements that involve risks and
uncertainties. Discussions containing such forward-looking statements may be
found in the material set forth under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business," "Business -- Business Strategy,"
"Business -- Acquisition Strategy," "Business -- Business Development and
Marketing" and "Business -- Clients," as well as in this Prospectus
generally. While forward-looking statements are sometimes presented with
numerical specificity, they are based on a variety of assumptions made by
management regarding future circumstances over which the Company has little or
no control. A number of important factors, including those identified in this
paragraph or discussed elsewhere in this Prospectus, could cause the Company's
actual results to differ materially from those depicted in forward-looking
statements or financial information. Actual results may differ from
forward-looking results for a number of reasons, including the following: (i)
changes in world economic conditions (including, but not limited to, the
potential instability of governments and legal systems in countries in which the
Company conducts business, and significant changes in energy prices and currency
valuations); (ii) changes in client demands as they affect levels of capital and
maintenance expenditures (including, but not limited to, the effect of strikes
at clients' facilities, variations in backlog and the impact of changes in
business cycles); (iii) competitive factors (including, but not limited to,
changes in client contract terms and procedures and the introduction of new
design and other processes by existing and new competitors); (iv) changes in
operating costs (including, but not limited to, the effect of changes in the
Company's engineering processes, changes in costs associated with varying levels
of operations, changes resulting from different levels of clients' demands and
changes in cost of labor and benefits); (v) the success of the Company's
operating plan (including, but not limited to, its ability to achieve the total
planned benefits of its strategic plan, its ability to integrate acquisitions
into Company operations, and the ability of recently acquired companies to
achieve satisfactory operating results); and (vi) unanticipated litigation,
claims or assessments (including, but not limited to, claims or problems related
to contract, professional errors and omissions and other liability claims).

                                  THE COMPANY

     OEI was formed in October 1997 by Petrocon's management to conduct the
Offering, simultaneously consummate the Pending Acquisitions and continue
Petrocon's successful acquisition program. Petrocon is a multidisciplined
engineering company, which provides a full range of process, civil, structural,
mechanical, instrument and electrical engineering and design services,
principally to the oil and gas, petroleum processing and pulp and paper
industries both domestically and abroad. Petrocon also designs, engineers,
programs and installs automated control systems for specific applications,
primarily for the downstream petroleum and chemical processing industries.
Petrocon, formed in 1988, is headquartered in Beaumont, Texas, with offices in
Houston, Texas, Lake Charles and Baton Rouge, Louisiana, Saudi Arabia and Abu
Dhabi. At December 31, 1997, Petrocon had approximately 1,144 employees,
including 854 engineers, designers and draftsmen and 125 construction managers,
inspectors and technicians. Petrocon has experienced significant growth in its
ten-year history, having increased its revenues from approximately $4.0 million
in 1988, to approximately $92.6 million in 1997, in large part through
acquisitions. Since 1988, Petrocon has made more than 13 acquisitions, gaining
in the process valuable experience in negotiating, closing and successfully
integrating acquisitions. According to ENR'S 1997 ranking of the top 500
engineering and design firms in the United States, Petrocon ranked   th in terms
of client billings.

     Concurrently with, and as a condition to, the closing of the Offering, OEI
will consummate the Pending Acquisitions. For a description of the transactions
in which Petrocon and the Acquired Companies will be acquired and the
consideration to be paid by OEI for each of them, see "-- Summary of Terms of
the Pending Acquisitions" and "Certain Transactions -- Organization of OEI."
The Acquired Companies are:

     PS&S:  Paulus, Sokolowski and Sartor, Inc. ("PS&S") provides total
design, engineering, geotechnical and environmental services to the
pharmaceutical, industrial, entertainment and utility industries, as well as to
commercial, institutional and public sector clients in the United States and

                                       15
<PAGE>
     C&I:  Chemical & Industrial Engineering, Inc. ("C&I") provides full
engineering, procurement and construction management services, with
state-of-the-art 3D modeling capabilities, principally to the refining,
chemical, food and beverage, pharmaceutical and utility industries, both
domestically and internationally. C&I was founded in 1983 and maintains its

ranked          th, based on client billings, in ENR'S 1997 ranking of the top
500 engineering and design firms in the United States.

     SUMMARY OF TERMS OF THE PENDING ACQUISITIONS:  Subject to certain
adjustments described below, the aggregate consideration payable to consummate
the Pending Acquisitions consists of (i) approximately $27.8 million in cash,
(ii) 5,053,027 shares of Common Stock, (iii) 654,099 shares of Common Stock and
approximately $3.4 million, which will be placed in escrow, and which will be
subject to a maximum three-year earnout arrangement with respect to one of the
Pending Acquisitions, (iv) options to purchase 768,384 shares of Common Stock to
be issued in connection with the Petrocon acquisition (the "Replacement
Options") and (v) warrants to purchase 357,579 shares of Common Stock to be
issued in connection with the Petrocon acquisition (the "Replacement
Warrants"). The Replacement Options and Replacement Warrants will be in the
money at the closing of the Offering in the aggregate amount of approximately
$   million (assuming an initial public offering price of $     per share).

     The Company will assume and repay upon or shortly after the Closing of the
Offering, certain of the then outstanding indebtedness of Petrocon and the
Acquired Companies, which as of December 31, 1997 aggregated approximately $28.1
million ($21.8 million of which will be repaid from proceeds of the Offering and
$6.3 million of which will be repaid from cash on hand), attributable as
follows: Petrocon -- $16.4 million; PS&S -- $1.9 million; GEI -- $3.6 million;
W-I -- $6.1 million; and C&I -- $0.1 million. The Company will also repay to
Equus II funds advanced to OEI to pay expenses of the Offering (estimated to be
approximately $2.5 million as of the closing of the Offering). Before the
closing of the Pending Acquisitions, W-I and PS&S, each of which is an S
corporation, are expected to distribute cash to their respective stockholders in
amounts accumulated in their respective accumulated adjustment accounts ("AAA
accounts") after December 31, 1997. An AAA account generally represents
undistributed earnings of an S corporation on which taxes have been or will be
paid by its stockholders. Before the closing of the Pending Acquisitions,
certain of the Acquired Companies will make other distributions to their
stockholders of certain assets and related liabilities with an aggregate net
book value of approximately $9.0 million.

     The Replacement Options and Replacement Warrants to be issued in the
Petrocon acquisition will replace options and warrants to purchase shares of
Petrocon common stock granted to employees and issued in connection with a prior
Petrocon acquisition. The aggregate purchase price which would have otherwise
been payable for Petrocon has been reduced by $4.2 million as a result of the
grant of the Replacement Options and Replacement Warrants.

     The purchase price for Petrocon was reduced by $2.0 million based on a
negotiated discounted value of projected annual earnout payments due by Petrocon
to the former shareholders of RPM Engineering, Inc. ("RPM") through 2001 in
connection with the RPM acquisition in October 1996. The additional earnout
payments, if any, will be accounted for as additional goodwill and amortized
over the applicable amortization period. See Note 15 to the Notes to the
Petrocon Consolidated Financial Statements.

     A portion of the purchase price for GEI will be subject to a maximum
three-year earnout arrangement. Upon the closing of the GEI acquisition,
approximately $3.4 million in cash and 654,099 shares of Common Stock will be
placed in escrow and held for subsequent distribution to the former GEI
stockholders, or returned to the Company, depending on the future financial
performance of GEI. Distributions from the escrow will be made annually to the
former GEI stockholders if certain cumulative financial performance thresholds
are achieved by GEI within the three-year period, or earlier if those thresholds
are achieved sooner. The additional earnout payments, if any, will be accounted
for as additional goodwill and amortized

                                       16
<PAGE>
over the applicable amortization period. Any escrowed stock and cash not
distributed to the former GEI stockholders after three years will be returned by
the escrow agent to the Company.

     The consideration being paid by the Company for each Acquired Company was
determined by customary and usual negotiations between the Company and
representatives of that Acquired Company. The consideration being paid for
Petrocon was determined using the same valuation methodology used to negotiate
the consideration being paid to the stockholders of the Acquired Companies,
except that in the determination of the Petrocon consideration, a higher pricing
multiple was applied to Petrocon's adjusted earnings. See "Certain
Transactions."

     The closing of each Pending Acquisition is subject to customary conditions.
They include, among others: the continuing accuracy of the respective
representations and warranties made by Petrocon and the Acquired Companies,
their respective principal stockholders and OEI; the performance of each of
their respective covenants included in the agreements relating to the Pending
Acquisitions; and the absence of a material adverse change in the results of
operations, financial condition or business of Petrocon and each Acquired
Company.

     No assurance can be given that the conditions to the closing of all the
Pending Acquisitions will be satisfied or waived or that each of the Pending
Acquisitions will close. For information regarding the employment agreements to
be entered into by certain key officers of Petrocon and the Acquired Companies,
see "Management -- Employment Agreements."

     STRATEGIC BENEFITS OF ACQUIRED COMPANIES:  The Company believes the
Acquired Companies provide the following strategic benefits, among others: PS&S
provides the Company with additional engineering services expertise in the
geotechnical and environmental disciplines, as well as broadening the Company's
client base to include the pharmaceutical and entertainment industries. GEI
contributes modular plant systems expertise, which the Company believes can be
cross-marketed to clients of certain of the other operating companies. W-I
enhances the Company's control systems capabilities, while at the same time
expanding the Company's client base into the upstream oil and gas market. C&I
expands the geographic coverage of the Company's engineering services segment,
broadens the Company's client base into the food and beverage and pharmaceutical
industries and provides the Company with state-of-the-art 3D modeling
capabilities that can be utilized at other operating companies.

                                USE OF PROCEEDS

     The net proceeds to the Company from the sale of the shares of Common Stock
offered by this Prospectus, after deducting underwriting discounts and
commissions and estimated offering expenses payable by the Company (including
the repayment of approximately $2.5 million of advances by Equus II to fund a
portion of the Offering expenses), are estimated to be approximately $53.0
million (approximately $61.4 million if the Underwriters exercise their
over-allotment option in full), assuming an initial public offering price of
$     per share (the midpoint of the estimated initial public offering price
range). Of the net Offering proceeds, approximately $27.8 million will be used
to pay the cash portion of the purchase prices for the Pending Acquisitions,
approximately $21.8 million will be used concurrently for the repayment of
certain outstanding indebtedness of Petrocon and the Acquired Companies
(excluding the repayment of the $2.5 million of advances by Equus II referred to
above) and approximately $3.4 million will be placed in escrow with respect to
one of the Pending Acquisitions. See "The Company -- Summary of Terms of the
Pending Acquisitions" and "Certain Transactions -- Organization of OEI."

     The indebtedness to be repaid from the proceeds of the Offering (some of
which has been guaranteed by stockholders of the Acquired Companies) bears
interest at rates ranging from 5.9% to 10.0% per annum. Such indebtedness would
otherwise mature at various dates through January 2004.

                                DIVIDEND POLICY

     It is the Company's current intention to retain earnings to finance the
expansion of its business. Any future dividends will be at the discretion of the
Board of Directors after taking into account various factors, including, among
others, the Company's financial condition, results of operations, cash flows
from operations, current and anticipated cash needs and expansion plans, the
income tax laws then in effect, the requirements of Delaware law, the
restrictions imposed by the New Credit Facility and any restrictions that may be
imposed by the Company's future credit facilities. The Company expects that its
New Credit Facility will require compliance with various loan covenants,
including restrictions on the payment of dividends. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Pro
Forma Combined -- Liquidity and Capital Resources."

(1) The pro forma combined balance includes $27.8 million of cash consideration
    payable in connection with the Pending Acquisitions.

(2) Includes an aggregate 654,099 shares which will be placed in escrow and will
    be subject to a maximum three-year earnout arrangement with respect to one
    of the Pending Acquisitions (see "The Company -- Summary of Terms of the
    Pending Acquisitions"), and excludes (i) an aggregate of          shares
    subject to options to be granted or allocated for grant on or prior to the
    closing of the Offering under the Incentive Plan,        of which will have
    an exercise price equal to the initial public offering price per share and
    768,384 of Replacement Options which will have a weighted average exercise
    price per share of $7.68, and (ii) an aggregate of 357,579 shares subject to
    the Replacement Warrants to be issued in connection with the Petrocon
    acquisition and which have an exercise price per share of $9.42. See

                                    DILUTION

     The deficit in pro forma combined net tangible book value of the Company as
of December 31, 1997 was approximately $   million, or approximately $   per
share, after giving effect to the Pending Acquisitions and the net incurrence of
indebtedness by the Company since December 31, 1997. The deficit in pro forma
net tangible book value per share represents the amount by which the Company's
pro forma total liabilities exceeded the Company's pro forma net tangible assets
as of December 31, 1997, divided by the number of shares to be outstanding after
giving effect to the Pending Acquisitions. After giving effect to the sale of
the          shares offered hereby and deducting the estimated underwriting
discounts and commissions and estimated offering expenses payable by the
Company, the Company's pro forma net tangible book value as of December 31, 1997
would have been approximately $   million, or approximately $   per share, based
on an assumed initial public offering price of $     per share (the midpoint of
the estimated initial public offering price range). This represents an immediate
increase in pro forma net tangible book value of approximately $   per share to
existing stockholders and an immediate dilution of approximately $     per share
to new investors purchasing shares in the Offering. The following table
illustrates this per share pro forma dilution:

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

     The following discussion should be read in conjunction with the financial
statements and related notes thereto and "Selected Historical and Pro Forma
Combined Financial Data" appearing elsewhere in this Prospectus.

INTRODUCTION

     The Company's revenues are primarily derived from engineering, design and
related services provided to its clients. Direct costs consist primarily of
labor, material and other related expenses necessary to complete the various
engineering and design projects. General and administrative expenses consist
primarily of executive compensation and related benefits, administrative
salaries and benefits, office supplies, rent, utilities, insurance and
professional fees.

     Petrocon and the Acquired Companies have been managed throughout the
periods discussed below as independent private companies, and their results of
operations reflect different tax structures (S corporations and C corporations),
which have influenced, among other things, their historical levels of owners'
compensation. Some owners of these companies and certain key employees have
prospectively agreed to certain reductions in their compensation and benefits in
connection with the Pending Acquisitions.

     OEI has conducted no operations to date other than in connection with the
Offering and the Pending Acquisitions. The Company intends to integrate these
businesses and their operations and administrative functions. The integration
process may present opportunities to reduce costs through the elimination of
duplicate functions and through economies of scale, but will necessitate
additional costs and expenditures for corporate management and administration.
The Company will also incur corporate expenses related to being a public
company, implementation of an acquisition program and systems integration. These
various costs and possible cost-savings may make comparison of historical
operating results not comparable to, nor indicative of, future performance. No
such cost savings were reflected in the pro forma combined statement of
operations data, except for compensation reductions provided for in the
agreements entered into in connection with certain of the Pending Acquisitions
and other known cost eliminations.

     In October 1997 and March 1998, OEI sold         shares of Common Stock to
its management, all but one of whom are members of the management of Petrocon.
As a result, the Company recorded a non-recurring, non-cash compensation charge
of $6.4 million and $0.4 million in the fourth quarter of 1997 and first quarter
of 1998, respectively, representing the difference between the amount paid for
the shares and the estimated fair value of the shares, which value has been
discounted from the estimated initial public offering price due primarily to
restrictions on the sale and transferability of the shares issued.

     In July 1996, the SEC issued Staff Accounting Bulletin No. 97 ("SAB 97")
relating to business combinations immediately prior to an initial public
offering. SAB 97 requires that these combinations be accounted for using the
purchase method of accounting. Under the purchase method, the owners of the
company that receive the largest portion of voting rights in the combined
enterprise as a result of the Pending Acquisitions are presumed to be the
accounting acquirer. Accordingly, Petrocon has been designated as the accounting
acquirer. For the Acquired Companies, $59.1 million, representing the excess of
the fair value of the merger consideration to be received over the fair value of
the net assets to be acquired, will be recorded as goodwill on the Company's
balance sheet. This goodwill will be amortized over a 40-year period as a
non-cash charge to the Company's statements of operations. The pro forma impact
of this amortization expense, which is non-deductible for federal income tax
purposes, is $1.5 million per year on an after-tax basis.

PRO FORMA COMBINED -- LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 1997, on a pro forma combined basis, after giving effect to
(i) the net incurrence of indebtedness by the Company since December 31, 1997,
(ii) the Pending Acquisitions, (iii) the closing of the Offering and the
Company's application of the net proceeds therefrom to repay certain
indebtedness of Petrocon and the Acquired Companies (approximately $21.8
million), (iv) the repayment of an additional

                                       23
<PAGE>
$6.3 million of Petrocon indebtedness from cash on hand and (v) $0.1 million of
advances by Equus II, which have been used to pay a portion of the expenses of
the Offering (which advances are estimated to aggregate $2.5 million at the time
the Offering closes), the Company would have had an aggregate of $3.7 million of
cash and short-term investments, $18.0 million of working capital and no
long-term debt obligations.

     The Company has recently received a commitment letter from          to
provide the New Credit Facility, which would be available upon the closing of
the Offering. According to the proposed New Credit Facility terms, the Company
would have a line of credit of up to $       million, which may be used for
general corporate purposes, including refinancing of certain indebtedness of
Petrocon and the Acquired Companies, acquisitions, capital expenditures and
working capital. The Company expects the New Credit Facility will require
compliance with various affirmative and negative covenants, including, among
others, (i) maintenance of certain financial ratios, (ii) a restriction on
additional indebtedness and (iii) restrictions on liens, guarantees, advances,
dividends and business activities unrelated to the Company's existing
operations. Failure to comply with such covenants and restrictions would
constitute a default under the New Credit Facility. The New Credit Facility is
subject to negotiation of definitive documentation and certain other customary
conditions, and there can be no assurance that the Company will be able to
obtain the New Credit Facility on terms acceptable to the Company.

     The Company intends to pursue further acquisition opportunities. The
Company expects to fund future acquisitions through the issuance of additional
Common Stock, borrowings (including amounts available under the New Credit
Facility) and cash flow from operations. To the extent the Company funds a
significant portion of the consideration for future acquisitions with cash, it
may have to increase the amount available under the New Credit Facility or
obtain other sources of financing. There can be no assurance such financing will
be available on terms acceptable to the Company. The Company expects that its
cash flow from operations will provide cash sufficient to meet the Company's
normal working capital needs, debt service requirements and planned capital
expenditures for property and equipment (exclusive of acquisitions of other
businesses) for at least the next several years. On a combined basis, the
Company made capital expenditures for property and equipment of approximately
$1.6 million and $1.9 million in 1996 and 1997, respectively. The Company's
capital expenditures for 1998 are expected to be approximately $1.3 million,
primarily for computer equipment and software, excluding capital expenditures
for acquisitions.

     Due to the relatively low levels of inflation experienced in 1997,
inflation did not have a significant effect on the pro forma combined results of
operations of the Company in that period.

SEASONALITY

     The Company historically has experienced quarterly fluctuations in
revenues, operating income and cash flows. In recent years, the Company has
experienced greater revenue, operating income and cash flows in the second and
third calendar quarters as compared with the other two calendar quarters,
primarily as a result of holidays and inclement weather during the first and
fourth calendar quarters and delays in expenditures until after completion of
the Company's clients annual budgeting process, which normally occurs during the
first calendar quarter.

IMPACT OF YEAR 2000

     The Company is currently in the process of evaluating its computer software
programs and operating systems to ensure such programs and systems will be able
to process transactions in the year 2000. However, the Company does not believe
that the costs to modify its programs or systems will be material to its
financial condition or results of operations. The Company does not currently
have information concerning the year 2000 compliance of its clients and
suppliers. The failure of the Company's clients and suppliers to achieve year
2000 compliance could have a material adverse effect on the Company's financial
condition and results of operations.

</TABLE>

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

     Revenues for 1997 increased by $30.7 million, or 49.6% to $92.6 million
from $61.9 million for 1996. This increase was principally due to the
acquisitions of Alliance Engineering, Inc. ("AEI"), RPM/Barnard & Burke
("RPM") and Triangle Engineers & Constructors, Inc. ("TE&C") in February
1997, October 1996 and July 1996, respectively. These entities contributed
revenues of $39.7 million in 1997 as compared to $6.1 million in 1996. This
increase was partially offset by a reduction in revenues at Petrocon (excluding
revenues attributable to the acquisitions) primarily as a result of the transfer
of an aggregate of approximately $3.5 million of revenues to PAL and the
acquired companies.

     Gross profit for 1997 increased by $8.3 million, or 65.9%, to $20.9 million
from $12.6 million for 1996. The gross margin increased to 22.6% in 1997 from
20.4% in 1996. This increase was principally due to the acquisitions of AEI and
RPM, which achieved generally higher gross margins than the other Petrocon
subsidiaries. AEI, RPM and TE&C contributed aggregate gross profit for 1997 of
$10.6 million as compared to $1.6 million for 1996.

     General and administrative expenses for 1997 increased by $5.9 million to
$15.5 million from $9.6 million for 1996, primarily as a result of the AEI, RPM,
and TE&C acquisitions, the addition during June 1996 of a corporate acquisition
staff and an increase in office work as contrasted with in-plant assignments.
AEI, RPM and TE&C accounted for $7.4 million of general and administrative
expenses for 1997 as compared to only $1.2 million in 1996. In addition, office
work generally carries higher general and administrative expenses but also
generates higher margins than in-plant assignments.

     Other income (expense) for 1997 increased by $(0.6) million to $(1.1)
million from $(0.5) million for 1996. This increase was primarily due to (i) a
$1.0 million increase in interest expense resulting from increased borrowings
needed to fund acquisitions, a shareholder preferred stock buy-back program and
working capital requirements and (ii) a $0.4 million charge related to the
write-off of certain leasehold improvements and other property. These expense
increases were partially offset by a $1.0 million increase in the earnings of
PAL reported under the equity method.

     Income from continuing operations for 1997 increased by $1.3 million, or
86.7%, to $2.8 million from $1.5 million for 1996.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

     Revenues for 1996 increased by $9.5 million, or 18.1%, to $61.9 million
from $52.4 million in 1995. This increase was primarily the result of the
acquisitions of RPM and TE&C, which contributed revenues of $6.1 million in
1996. In addition, internal growth accounted for an increase of $3.4 million
based in part on the receipt of significant incentive payments on several large
projects completed in 1996.

     Gross profit for 1996 increased by $2.4 million, or 23.5%, to $12.6 million
from $10.2 million for 1995, primarily due to the increase in revenues and from
the RPM and TE&C acquisitions. The gross

                                       25
<PAGE>
margin increased to 20.4% in 1996 from 19.6% in 1995. This improvement was
principally due to the RPM acquisition, which achieved generally a higher gross
margin than the other Petrocon subsidiaries.

     General and administrative expenses for 1996 increased by $1.2 million to
$9.6 million from $8.4 million for 1995, primarily as a result of the RPM and
TE&C acquisitions and the addition of the corporate acquisition staff in June
1996. RPM and TE&C accounted for $1.2 million of general and administrative
expenses in 1996.

     Other income (expense) for 1996 increased by $(0.4) million to $(0.5)
million from $(0.1) million for 1995. This increase related principally to (i) a
$0.1 million increase in interest expense due to increased borrowings to fund
acquisitions and the shareholder preferred stock buy-back program and (ii) a
$0.5 million decrease in the earnings of PAL reported under the equity method.
The decrease in the earnings of PAL resulted primarily from the imposition of
quota requirements under certain client contracts that have since been resolved.

     Income from continuing operations for 1996 increased $0.3 million to $1.5
million from $1.2 million for 1995.

PETROCON -- LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 1997, Petrocon had cash and cash equivalents of $2.3
million. In addition, Petrocon has a $14 million revolving credit facility, of
which $11.6 million was outstanding at December 31, 1997. This credit facility
is secured by the Company's accounts receivable and requires Petrocon to
maintain certain financial covenants regarding net worth and cash flow, as well
as certain financial ratios, including fixed charge coverage and specified
levels of certain other items. The credit facility expires in August 1999. The
Company intends to repay this credit facility with proceeds from the Offering
and enter into the New Credit Facility. See "Use of Proceeds" and "-- Pro
Forma Combined -- Liquidity and Capital Resources."

     For 1997, net cash provided by operations totaled $3.3 million as compared
to $4.6 million for 1996. Cash provided by operations for 1997 consisted of net
income of $2.8 million, plus non-cash revenue and expenses of $1.8 million, less
changes in working capital of $(1.3) million in the aggregate.

     Non-cash revenue and expenses for 1997 included depreciation and
amortization expense of $1.8 million. Changes in working capital included a $3.3
million increase in accounts receivable as a result of the higher revenues in
1997, and a $1.4 million increase in costs and estimated earnings in excess of
billings on uncompleted contracts due to an increase in projects in progress but
not completed at year end. This use of working capital was partially offset by
increases in accounts payable of $0.8 million and accrued salaries and fringe
benefits of $2.8 million, primarily due to the higher revenues in 1997 and the
AEI acquisition.

     Capital expenditures for 1997 were $1.2 million, principally for the
purchase of computer equipment and software and certain AEI leasehold
improvements.

     In February 1997, a wholly-owned subsidiary of Petrocon merged with AEI.
Cash used for the acquisition, net of cash acquired, was $3.1 million in the
aggregate. In August 1997, Petrocon repurchased 154,531 shares of its
outstanding Series A preferred stock in exchange for cash of $0.9 million and
other consideration. At December 31, 1997, net increases in amounts outstanding
under PEI's credit facility and notes payable were $3.8 million in the
aggregate, principally to fund the AEI acquisition and for working capital
requirements.

     Petrocon capital expenditures for 1998 are expected to be approximately
$1.0 million, primarily for Petrocon computer equipment and software.

                               INDUSTRY OVERVIEW

GENERAL

     Engineering is an integral part of virtually every type of construction,
manufacturing, processing, natural resource extraction, power generation or
transportation activity. Firms providing engineering services range from small,
local firms employing several or even a single engineer, to global organizations
whose professionals number in the thousands and which have worldwide
capabilities. Some engineering firms confine their activities to "pure"
planning and design functions, while many combine their engineering work with
varying degrees of construction, architectural and other activities. Some
engineering firms are specialized, either on a discipline or industry basis, and
others are multidisciplined and serve a broader base of clients.

     Given the breadth of activities constituting "engineering" and the
diversity of the firms conducting these activities, generalizations and
characterizations are difficult and largely subjective. ENR annually reports on
and ranks by client billings what it calls "The Top 500 Design Firms," which
include U.S.-based engineer-constructor, engineer-architect and other hybrid
organizations, as well as exclusively design and planning firms. Ranked
companies classify themselves as concentrating in specified areas of work.
According to ENR'S report for 1997, its 500 top ranked firms as a group billed
their clients $         billion in 1997, representing a    % [INCREASE]
[DECREASE] over 1996. For 1996, the "Top 500's" total reported client billings
by areas of work were as follows [UPDATE W/'97 NUMBERS]:

     Of the total 1997 billings reported by ENR'S "Top 500," $
billion, or    %, was represented by domestic billings, and $
billion, or    %, was represented by international work. Out of the "Top 500"
firms,       firms reported increases in their professional staff during 1997,
versus          firms which reported losses or no change in professional staff,
and          firms reported higher backlogs at the end of the year, while
firms reported lower or unchanged backlog levels.

INDUSTRY CONDITIONS

     The markets served by the ENR ranked firms and the many thousands of
unranked U.S. and foreign-based design and engineering firms make up a global
construction market estimated to exceed $3 trillion annually. In the United
States, over the last decade, the annual value of construction put in place has
been assessed by the U.S. Department of Commerce at over $400 billion in current
dollars. The market for engineering services has experienced significant growth
in recent years as reflected by an increase in annual billings by ENR'S "Top
500" of $[*] billion, or [*]%, from $29.4 billion in 1995 to $[*] billion in
1997. The Company believes there will be a continued strong demand for
engineering services within the United States and internationally due to, among
other things, the following factors:

          ANTICIPATED SPENDING ON INFRASTRUCTURES.  The United States
     infrastructure needs have been much publicized. Upgrades and expansions of
     the existing infrastructure, including highways, water and sewer lines and
     gas and other power utilities are currently estimated by the Associated
     General Contractors of America to require more than $3 trillion over the
     next 20 years, averaging approximately $180 billion each year. Similarily,
     significant infrastructure expenditures are expected in

                                       27
<PAGE>
     Europe, with construction spending estimated at approximately $500 billion
     per year. In lesser developed countries, increasing urbanization and the
     growing demand for an improved standard of living are expected to generate
     substantial engineering and construction infrastructure projects.

          CONTINUED IMPROVEMENT OF INDUSTRIAL OPERATING AND PROCESSING
     EFFICIENCIES.  The industrial construction market both within the United
     States and abroad is expected to continue to be driven by competitive and
     technological forces. Global competition is believed by management to be
     motivating plant owners to increase their spending on solutions that
     further automate and streamline their businesses. As a result, the global
     demand for technically diverse engineering services is expected to continue
     to increase.

          CONTINUED INCREASES IN REGULATORY REQUIREMENTS IMPACTING U.S.
     INDUSTRY.  Regulations regarding the environmental and safety compliance of
     U.S. businesses continue to create significant construction and engineering
     opportunities. For example, the EPA currently estimates that U.S. pulp and
     paper manufacturers will be required to make more than $1.8 billion in
     total capital expenditures and $277 million annually to comply with surface
     water discharge limitations currently in effect. The EPA further estimates
     that approximately $140 billion must be spent over the next 20 years to
     conform U.S. wastewater and hazardous waste disposal sites to comply with
     current regulatory requirements.

          CONTINUED TRENDS IN OUTSOURCING OF PLANT OPERATION AND
     MAINTENANCE.  Technical staffing by engineering firms should continue to
     expand as refineries and manufacturing and processing plants rely
     increasingly on outside firms to provide engineering services related to
     plant operations and maintenance. Industrial clients have continued to
     reduce their in-house engineering staffs related to these areas as a result
     of outsourcing non-core business functions and industry downsizing.
     Industry studies estimate that between 20% and 50% of the total cost of
     running a plant is represented by maintenance and that the total potential
     plant maintenance market ranges from $300 billion to $500 billion annually.

TREND TOWARD CONSOLIDATION

     The Company believes that more than 28,000 U.S. firms, and an even greater
number of foreign firms, offer some form of engineering and design services. The
Company also believes that these firms are combining at the local, national and
international levels as they seek to expand their geographic coverage, broaden
their professional capabilities, expand within existing geographic markets and
specialties, and leverage their engineering capabilities through
cross-marketing. The Company believes that the same motivating factors that have
led some of Europe's largest firms to acquire or obtain controlling interests in
some of the largest and best known engineering firms in the United States, and
VICE VERSA, will continue to induce combinations among local, regional, national
and foreign firms of every size and type.

     The Company further believes that at the mid-size and regional firm level,
several other factors are contributing to an increasing number of firms seeking
to combine with other, larger organizations. Frequently, the founders and
principals of these firms are engineers or designers first, and professional
business managers second. Their firm's growth has imposed on them greater
management responsibilities at the expense of their professional practice, and
many are seeking either relief from or assistance with their management burdens.
Also, regardless of their legal form, many such firms, over the life of their
development, have assumed partnership-like characteristics as growing numbers of
professionals have become equity owners in the firm, a process which often
raises difficult governance and other issues that can be solved by a combination
with a larger, professionally managed firm. Furthermore, many of these firms
recognize their need for overhead reductions, but feel constrained in making
them by what often are non-economic factors. The Company believes that in many
instances, such firms may view their acquisition as an opportunity to achieve
appropriate and necessary overhead reductions without having to self-impose
them. Finally, the growth opportunities of these firms are often limited by
bonding and other performance guarantee requirements which are beyond their
financial capabilities, but which could be satisfied by access to greater
financial resources through association with a larger firm.

                                    BUSINESS

GENERAL

     The Company is a diversified engineering company providing engineering
services and engineered systems to a broad range of industrial, commercial and
institutional clients throughout the United States and internationally. The
Company's multidisciplined expertise enables it to offer its clients total
design and engineering solutions extending from project inception through
completion, start-up and operation, within multiple industries and across
diverse geographic markets. During 1997, the Company was involved in engineering
projects in 26 states and over 21 countries worldwide, generating pro forma
combined revenues of $169.1 million, of which $119.5 million, or 70.7%, was from
domestic projects, and $49.6 million, or 29.3%, was from international work.

     OEI was formed in October 1997 by Petrocon's management to conduct the
offering, simultaneously consummate the Pending Acquisitions and continue
Petrocon's successful acquisition program. The Company, through Petrocon, has
grown significantly through acquisitions, having acquired more than 13
engineering firms since 1988. As a result of the Pending Acquisitions and the
Offering, the Company believes it will have greater financial, technical and
professional resources, which will enable it to aggressively continue its
successful acquisition strategy, enhance its technical capabilities and expand
its already diversified client base.

     The Company operates in two principal segments: engineering services and
engineered systems. The Company's engineering services encompass all aspects of
the process, civil, structural, mechanical, instrument, electrical, geotechnical
and environmental engineering and design disciplines, providing its clients with
a single source for all their design, engineering and permitting needs. The
Company has designed and engineered facilities ranging from refineries,
petrochemical plants, pulp and paper processing plants and wastewater treatment
facilities, to food and beverage processing plants, pharmaceutical plants and
laboratories, electronics manufacturing facilities, hotels and casinos. The
Company's engineered systems are primarily custom designed, built, programmed
and installed on a fixed-price, turnkey basis and include control and
instrumentation systems and modular processing plants primarily for the oil and
gas, refining and chemical processing industries. During 1997, approximately
$124.5 million, or 73.6%, of the Company's pro forma combined revenues were
attributable to engineering services and $44.6 million, or 26.4%, were
attributable to engineered systems. The Company provides engineering services
and engineered systems to a number of Fortune 100 companies through a staff of
over 1,600 employees, including approximately 1,100 engineers and design
professionals as of December 31, 1997.

BUSINESS STRATEGY

     The Company has developed a strategic plan to:

     EXPAND AND DIVERSIFY THROUGH ACQUISITIONS.  The Company intends to
aggressively continue its acquisition program targeted at well-established,
profitable engineering companies offering engineering services and engineered
systems similar or complementary to those offered by the Company. See
"-- Acquisition Strategy" and "-- Acquisition History." The key elements of
the Company's acquisition strategy are to:

          ENTER NEW GEOGRAPHIC MARKETS.  The Company intends to expand its
     geographic coverage by acquiring well-established and highly respected
     local and regional firms within the U.S., as well as foreign firms, with
     operations in geographic areas not currently served by the Company.

          EXPAND AREAS OF TECHNICAL EXPERTISE.  The Company intends to expand
     the scope of its technical expertise by acquiring firms with acknowledged
     expertise and experience in specialized service areas that are not offered
     by the Company or in which the Company does not enjoy a widely recognized
     reputation. This would provide the Company's existing and future clients
     with a broader range of services.

                                       29
<PAGE>
          STRENGTHEN PRESENCE WITHIN EXISTING GEOGRAPHIC MARKETS AND
     SPECIALTIES.  The Company intends to acquire firms in markets currently
     served and specialties currently offered by the Company in order to
     increase the professional resources available to the Company and secure
     larger projects.

          ENHANCE CROSS-MARKETING OPPORTUNITIES  The Company also intends to
     enhance its cross-marketing opportunities by acquiring other engineering
     firms whose services and systems can be packaged or cross-marketed with the
     Company's existing services and systems.

     ACCELERATE INTERNAL GROWTH.  The principal elements of the Company's
internal growth strategy are to (i) attract larger, higher-margin projects by
virtue of increased financial, professional and technical resources, (ii)
leverage the Company's capabilities and expertise through cross-marketing and
(iii) develop new partnering relationships and other strategic alliances.

     IMPROVE OPERATING MARGINS.  The Company believes that combining Petrocon
and the Acquired Companies will provide significant opportunities to increase
the Company's profitability. The key components of this strategy are to:

          INCREASE OPERATING EFFICIENCIES.  The Company believes that it will be
     able to increase its overall staff utilization rate by more effectively
     deploying and allocating its professional resources. The Company intends to
     accomplish this goal with the aid of computer networking, which will allow
     work to be sent instantly by computer to the location of available
     resources, and by extending the concepts of the Company's "Vision 2000,"
     a project-driven approach which the Company has had in place for almost
     four years and which has helped Petrocon lower significantly its
     non-billable hours and maximize its rate of chargeability. The Company also
     expects improvements in its overall staff utilization rate as a result of:
     (i) increased utilization of highly specialized personnel based upon a
     larger number of Company-wide engineering projects; (ii) increased
     flexibility to make staff adjustments at those operating companies located
     in geographic areas with more limited talent pools; and (iii) the
     Company-wide application of Petrocon's operating experience in the Texas
     Gulf Coast area, which is one of the country's most competitive
     environments for engineering services.

          CENTRALIZE APPROPRIATE ADMINISTRATIVE FUNCTIONS.  The Company believes
     that opportunities exist to improve operating margins by consolidating the
     administrative functions of the Company, such as finance, insurance,
     employee benefits and accounting.

          EXPLOIT PURCHASING POWER.  The Company expects to use its increased
     purchasing power to gain volume discounts both for itself and in connection
     with its procurement services for its clients. These discounts will enable
     the Company to secure larger margins on its turnkey projects and
     fixed-price contracts, and to potentially secure additional contracts in
     situations where these discounts can be passed through to its clients.

     OUTSOURCE CONSTRUCTION ACTIVITIES.  While the Company recognizes the
current trend among project owners and operators toward turnkey projects, under
which a single firm provides all engineering, procurement and construction
services associated with a project, the Company believes it can offer clients
these projects, without assuming all of their associated construction risks, by
forming joint ventures and other partnering relationships with specialized
construction firms. Similarly, in instances where the Company is asked or
required to take an equity interest in a project, the Company intends to seek
financial partners with capital available for that purpose, rather than
deploying its own capital in meeting any project equity requirements. The
Company believes that combining Petrocon and the Acquired Companies will result
in a larger firm, both financially and in terms of professional resources, and
thus a more attractive partnering candidate for potential construction and
financial partners.

     OPERATE ON A DECENTRALIZED BASIS.  The Company intends to manage its
operating companies and subsequently acquired companies on a decentralized
basis, with local management retaining responsibility for day-to-day operations,
profitability and growth. The Company's executive management intends to closely
monitor operating results of its operating companies and will provide direction
and guidance on operational matters, such as staff utilization rates, backlog
control and marketing and cross-selling opportunities, in an effort to improve
profitability at each operating level. The Company believes that

                                       30
<PAGE>
combining a decentralized management structure with strong, centralized
operating and financial controls geared to accountability will support the
entrepreneurial and creative culture at each of its operating companies, while
allowing the Company to capitalize on the local and regional market knowledge,
goodwill, name recognition and client relationships of each of the operating
companies.

ACQUISITION STRATEGY

     The Company intends to aggressively continue its acquisition program
targeting well-established and profitable companies offering engineering
services and engineered systems similar or complementary to those offered by the
Company. Acquisitions will be expected to expand the Company's geographic
coverage, broaden its technical capabilities or expertise, improve its market
share within existing geographic markets or specialties, or provide increased
cross-selling opportunities. Certain acquisitions will be large enough to
maintain their own operating and management structure, while other smaller
acquisitions will be folded into an existing operation without significantly
increasing the Company's infrastructure. From among the many thousands of
engineering companies estimated to be active in the United States, and the many
more thousands of foreign firms, the Company believes there will be no shortage
of acquisition candidates. The Company will selectively pursue acquisition
candidates based on the Company's acquisition criteria, such as profitability,
revenue growth potential, similar or complementary services, systems and client
bases that provide potential cross-selling opportunities, established
reputation, qualified and experienced management, professional and technical
personnel and geographic and cultural compatibility.

     The Company believes it will be regarded by acquisition candidates as an
attractive acquirer because of: (i) the Company's strategy for creating a
professionally managed engineering firm of internationally recognized stature;
(ii) the Company's decentralized operating strategy which emphasizes an ongoing
role for owners, management and key personnel of acquired firms, as well as
meaningful equity positions for these individuals which will enable them to
participate in the Company's growth and realize improved liquidity; (iii) the
Company's objective of maintaining a professional environment which will attempt
to preserve and capitalize on the entrepreneurial spirit, creativity and
ingenuity of the acquired firms' owners and professional personnel; (iv) the
potential for growth of both the acquired entity and the Company overall by
virtue of increasing the scope and variety of services which the acquired firm
and the Company can together make available to their existing client bases, as
well as increasing the size and variety of the projects which can be undertaken
by the acquired firm as a result of its access to greater financial, technical
and professional resources; and (v) the potential for increased profitability of
the acquired company due to centralization of administrative functions, enhanced
information and design systems capabilities and purchasing economies.

     The Company intends to use various combinations of its Common Stock, cash
and notes as consideration for future acquisitions. The consideration for each
future acquisition will vary on a case-by-case basis. The Company will finance
future acquisitions through funds provided by operations, by the New Credit
Facility and from the proceeds of future equity and debt financings. During
1998, the Company intends to register                shares of Common Stock
under the Securities Act for use in connection with future acquisitions.

ACQUISITION HISTORY

     Since 1988, the Company has experienced substantial growth through
acquisitions. Key members of the Company's management team have worked together
for several years at Petrocon, which has made over 13 acquisitions to date. In
the process, the Company's management has gained valuable experience in
sourcing, negotiating, closing and successfully integrating acquisitions. The
following table describes eight of the more strategically significant
acquisitions by the Company since 1988:

(1) Represents unaudited revenues for the fiscal year ending in the year
    immediately preceding the year of the acquisition.

(2) Acquisition of a 50% interest in what is now PAL.

(3) Represents 100% of PAL's revenues. No PAL revenues are included in the
    Company's revenues because it uses the equity method to account for PAL.

     Through these acquisitions, the Company has demonstrated the ability to
implement its acquisition strategy. The Company expanded internationally through
its acquisition of a 50% interest in PAL (formerly Eagleton Saudi Arabia
Limited), which has provided the Company with a presence in the Middle East and
surrounding countries. PAL has also provided cross-selling opportunities by
assisting the Company in securing engineering projects for its U.S-based
operating companies. The Company broadened its technical expertise in control
systems through a series of acquisitions, including DLH Associates and HTC,
Inc., which enabled the Company to immediately compete for a growing number of
control system project opportunities. The Company acquired Coastal Technical
Corporation to take advantage of an industry trend of outsourcing certain
in-plant engineering functions and as a hedge against cyclical downturns. The
acquisitions of RPM/Barnard & Burke, Triangle Engineers & Constructors, Inc. and
Alliance Engineering, Inc. have strengthened the Company's position in the Gulf
Coast region, while at the same time expanding the Company's engineering
capabilities in the upstream oil and gas market. These acquisitions also
permitted the Company to gain additional plant engineering projects with certain
of its long-term alliance clients by adding new office locations in close
proximity to their plants.

ENGINEERING ACTIVITIES

     The Company groups its engineering activities into two principal segments:
engineering services and engineered systems. The following table sets forth, for
the periods indicated, the contribution to the Company's combined revenues from
each of these segments:

     ENGINEERING SERVICES.  The Company's engineering service capabilities
encompass all aspects of the process, civil, structural, mechanical, instrument,
electrical, geotechnical and environmental engineering disciplines, providing
its clients with a single source for all their design, engineering and
permitting needs. This multidisciplined expertise enables the Company to offer
total design and engineering solutions extending from product inception through
completion, start-up and operation, within multiple industries and across
diverse geographic markets.

     The Company's services include feasibility studies, conceptual design,
detail engineering, site and environmental planning, evaluation and permitting,
procurement, project and construction management, inspection and verification,
maintenance, plant operations, quality assurance/control and information
technology. The Company has designed and engineered facilities ranging from
refineries, petrochemical plants, pulp and paper processing plants and
wastewater treatment facilities, to food and beverage processing plants,
pharmaceutical plants and laboratories, electronics manufacturing facilities,
hotels and casinos.

     The nature and variety of the Company's engineering services are
illustrated by the following representative listing of projects completed by the
Company:

      o   Total design, integration and project management for a substantial
          refinery upgrade project for Lyondell-Citgo in the Houston, Texas
          area.

      o   Total design, procurement, installation supervision and startup of a
          fruit processing plant in southern India.

      o   Engineering, procurement and construction management services for a
          significant distributed control system upgrade for a major refinery in
          the Middle East.

      o   Engineering, design, procurement, construction support and startup
          services for a process system to blend coffee for Pepsi-Cola
          International.

      o   Full range of environmental planning, permitting and engineering
          consulting services relating to a 25,000 seat waterfront amphitheater
          located in New Jersey.

      o   Design and permitting services related to a gas/odor collection system
          project for a major New York landfill.

      o   Total engineering and design services for a marine research
          laboratory, which includes a state-of-the-art 32,000 gallon aquarium
          with seawater filtration and water temperature and lighting controls
          for simulation of various aquatic conditions.

      o   Process engineering services for a substantial chemical plant project
          in mainland China for a major U.S. chemical company.

     The Company also provides engineers, designers and draftsmen to its clients
for assignment inside the clients' facilities. These staffing arrangements,
primarily with refineries and petrochemical and processing plants in the Texas
and Louisiana Gulf Coast region, include: partnering relationships with clients;
in-plant task forces operating under the Company's supervision; and
employee-lending arrangements where Company employees work under the client's
supervision. At December 31, 1997, approximately 400 Company

                                       33
<PAGE>
personnel were contracted for some form of in-plant assignment. The Company
intends to continue pursuing a strategy of placing employees on in-plant
assignments in order to take advantage of what it believes to be a sustained
trend toward outsourcing and single sourcing among plant owners and operators,
and as a hedge against cyclical slumps resulting from general economic or
industry specific conditions.

     ENGINEERED SYSTEMS.  The Company provides two primary types of engineered
systems: control and instrumentation systems and modular processing plants.

     CONTROL AND INSTRUMENTATION SYSTEMS.  The Company designs, engineers,
assembles, programs, installs, integrates and services control and
instrumentation systems for specific applications, principally in various energy
and processing related industries. The Company's control and instrumentation
systems are custom designed and include both conventional pneumatic and
hydraulic control systems and sophisticated electronic, microprocessor-based
controls employing programmable logic. Typical applications for the Company's
control and instrumentation systems include oil and gas production safety
systems, fire and gas detection systems, pipeline compressor station and data
acquisition systems, surface controls for subsea production systems and control
systems for oil and gas wells, engine and gas turbine driven compressors, pumps,
boilers and heaters, and processing equipment. The Company offers turnkey
electrical and instrumentation field construction services for equipment
packages, offshore oil and gas production facilities, pipeline compressor
stations, refineries and processing plants. All facets of control and
instrumentation system design, engineering, assembly and testing are performed
in-house by the Company, and the Company's full service field installation and
technical staff performs complete electrical and instrumentation installation
projects, start-up and commissioning services, modifications to existing
systems, on-site training and routine maintenance procedures for client
operating personnel. The Company's control systems unit does not produce
products for inventory and purchases component parts for its systems only on an
as-needed basis.

     MODULAR PROCESSING PLANTS.  The Company designs, engineers, fabricates and
installs modular processing plants for the oil and gas and petrochemical
industries. The Company specializes in cryogenic turbo-expander units which
employ extreme low temperatures in the processing of natural gas for the
extraction of ethane and heavier gas liquids and the removal of nitrogen and
other inerts. The Company also designs and builds extraction plants using
conventional refrigeration to remove propane and heavier gas liquids from
natural gas. Other modular plants designed and built by the Company include
plants for gas treatment, sulfur, dehydration and fractionation, crude
stabilization and production, MTBE, waste heat recovery and cogeneration, and
amine treatment. The Company has designed and built plants ranging in capacity
up to 450 million standard cubic feet per day for extraction plants, 250 million
standard cubic feet per day for gas treatment plants, 600 tons per day for
sulfur plants, 60,000 barrels per day for fractionation plants and 1.2 billion
cubic feet per day for gas dehydration plants.

     All mechanical, structural, civil, piping, electrical and instrumentation
engineering incorporated in the Company's modular plants is performed by the
Company. The Company's modular plants are constructed at its fabrication
facility in Houston, Texas. The plants are built on skids and transported to
their site either by the Company or its client depending on the client's
preference. If requested by the client, the Company provides full on-site
installation, testing and commissioning services for its modular plants.

     The Company believes that its modular plants offer advantages over
comparable plants constructed on site, including quicker and more predictable
delivery schedules, higher quality assurance due to the controlled environment
in which the plants are built, and lower costs attributable to simplified
materials delivery, quantifiable labor costs and simplified field installation.

     Historically, the Company has undertaken only a small number of high-margin
modular plant projects annually, and most of its plants were for installation in
the oil and gas producing regions of the United States, principally in Texas,
Louisiana, Oklahoma and New Mexico. In recent years, the Company has been
concentrating on building plants for foreign clients, for installation abroad,
since the Company believes foreign projects generally offer greater profit
opportunities. In 1997, the Company's two largest foreign projects were built
for installation in Argentina and the Ivory Coast, respectively.

                                       34

BUSINESS DEVELOPMENT AND MARKETING

     The Company believes marketing and business development are Company-wide
responsibilities, and all of the Company's project and other managers are
formally encouraged to be actively involved in business development efforts
through the maintenance of professional and personal relationships and through
the identification and pursuit of new business opportunities. Company managers
closely monitor the Company's client list to insure that all existing clients
are contacted on a regular basis so that the Company remains before the client
and aware of all current and proposed client projects.

     The Company also has 20 full-time business development managers who are
responsible for both maintaining existing client relationships and identifying
new clients, projects and markets. The Company business development managers are
located in Houston (six) and Beaumont (four), Texas; Baton Rouge (four) and Lake
Charles (one), Louisiana; Louisville, Kentucky (three); and Warren, New Jersey
(two). The Company has two full-time business development managers responsible
primarily for international business development. In addition, the Company
retains business development agents in Mexico City, three Saudi Arabia locations
and Lagos, Nigeria.

     In addition to the regional business development managers, the Company has
recently created the position of Executive Vice President of Marketing and
Development to implement, control, monitor, report and evaluate marketing
policies and procedures to be adopted on a corporate level and approved by the
President. These policies and procedures will be set after consultation with
management of the Company's primary operating locations and will be modified
from time to time as market and Company conditions warrant. Other
responsibilities of the Executive Vice President of Marketing and Development
will include developing, implementing, monitoring and evaluating policies and
procedures relating to cost-effective integration techniques at the operating
company level with emphasis on resource allocation, such as staff utilization,
work-load variances and man-hour cost-to-billing differentials, in an effort to
achieve periodic and long-term consolidated financial planning objectives, while
at the same time maintaining acceptable internal growth rates at the operating
companies.

OPERATIONS

     The Company intends to operate on a decentralized basis, with the
management of each operating company responsible for day-to-day operations,
profitability and growth. However, the Company intends to centralize certain
administrative activities from its executive offices. Centralized activities
will include accounting for the consolidated group, financing, business
development support, management information systems support, contract
administration, insurance and safety administration and audits. In addition, all
operating locations will be required to adhere to Company-wide policies and
procedures relating to financial reporting, internal controls, purchasing and
human resources and administration.

     The Company will also initiate "best practices" among all the operating
companies for project monitoring and cost controls, backlog reporting, risk
management and, where determined by the Company to be advisable, engineering
policies and procedures. The Company intends to establish a President's Council,
comprised of the president of OEI and the presidents of each of the Company's
significant operating companies, to meet periodically for the purpose of
implementing "best practices" and identifying areas where opportunities for
synergies may be realized.

     The Company intends to integrate in the near term the existing computer
system of Petrocon with each of the primary facilities of the Company's
significant operations. This system should increase the Company's overall staff
utilization rate by allowing the Company to instantly transmit work to the
location of available resources. The Company has recently retained an
integration coordinator to implement the integration of this system and other
centralized administrative functions.

COMPETITION

     In its engineering services segment, the Company competes nationally and
internationally with a large number of other firms of all sizes, ranging from
the industry's largest firms which operate on a worldwide basis to much smaller
regional and local firms. Among the firms larger than the Company, many offer a

                                       35
<PAGE>
broader range of services than does the Company, many concentrate their services
in one or more of the Company's service areas, and many have greater financial
and professional resources than the Company. The Company does not believe that
any one firm dominates or contributes a significantly large percentage of the
total volume of work performed in any particular service area.

     Competition in the Company's engineering services segment is primarily
centered on performance and the ability to provide the engineering, planning and
project execution skills required to complete projects in a timely and cost
efficient manner, as well as price. The high level of competition in this area
of the Company's business has fostered a trend away from the relatively riskless
cost-plus fee arrangements to pricing alternatives designed to shift to the
service provider, or requiring the service provider to at least share in, the
risks of cost overruns and inefficiencies in the delivery of services. These
alternatives include fixed-price, guaranteed maximum price, incentive fee,
competitive bidding, and other "value based" pricing arrangements. See "Risk
Factors -- Pricing and Related Risk Sharing" and "-- Contracts."

     In its engineered systems segment, the Company emphasizes, and believes it
is known for, the engineering quality and performance characteristics of its
systems, its total turnkey capabilities, its innovative design solutions and its
ability to meet promised delivery dates. The emphasis both clients and the
Company place on pricing tends to vary with cyclical conditions in the oil and
gas, petroleum and processing industries, with pricing becoming a more important
factor during industry downturns. The Company's control systems and modular
processing plants compete with similar systems built by other companies both
larger and smaller than the Company, some of which compete primarily on the
basis of pricing.

FOREIGN OPERATIONS

     The Company has performed engineering and construction management services
in over 25 countries, both directly and through its 50% interest in PAL, which
is headquartered in Al Khobar, Saudi Arabia and serves the entire Arabian Gulf
Region. In addition to its Al Khobar headquarters, PAL has branch offices in
Riyadh, Yanbu and Abu Dhabi, from which it services clients in Bahrain, Kuwait,
Oman, Qatar, Saudi Arabia and the United Arab Emirates. Through agents and
partners, the Company maintains offices in Mexico City, Mexico and Lagos,
Nigeria.

     For the years ended December 31, 1995, 1996 and 1997, combined revenues
from Company projects outside of the United States, excluding all PAL projects,
were approximately 19.2%, 29.3% and 29.3% of total revenues, respectively. The
Company accounts for its 50% interest in PAL by the equity method, and therefore
no PAL revenues are included in the Company's revenues. For the years ended
December 31, 1995, 1996 and 1997, PAL had revenues of approximately $9.2
million, $8.1 million and $16.5 million, respectively.

CONTRACTS

     The price provisions of the Company's contracts with its clients vary
greatly. However, these provisions can generally be grouped into one of three
categories: cost-plus; guaranteed maximum price; and fixed-price.

     COST-PLUS contracts provide for reimbursement of costs incurred by the
Company plus a predetermined fee or a fee based on a percentage of costs
incurred. This pricing arrangement presents the least risk to the Company.

     GUARANTEED MAXIMUM PRICE contracts are performed in the same manner as cost
plus contracts, except the total actual cost plus the fee cannot exceed the
guaranteed price negotiated between the Company and its client. If it does, then
the Company may bear all or a portion of the excess. Where the cost and fee are
less than the guaranteed price, the Company may share the savings with the
client on a predetermined basis.

     FIXED-PRICE contracts include both negotiated fixed-price contracts and
lump sum bid contracts that require the Company to perform work for a stated
amount. Under a negotiated fixed-price contract, the Company is first selected
as the contractor, and then the contract price is negotiated. Negotiated
fixed-price contracts are frequently agreed to in turnkey arrangements where the
Company has the opportunity to

                                       36
<PAGE>
perform feasibility studies and design work before negotiating the price. Under
lump sum bid contracts, the Company must bid against other firms based upon
specifications furnished by the client. Contract bidding carries certain
inherent risks, including the possibility of ambiguities in specifications,
problems with new technologies, strike delays, work stoppages and other
unforseen developments and changes that may occur over the contract period, that
are reallocated through the negotiation process. Although both forms of contract
involve a firm price for the customer, the lump sum bid contract presents the
greater degree of risk to the Company.

     The Company's control systems and modular processing plants are contracted
primarily on a lump sum, turnkey basis either FOB the Company or installed on
site. For modular processing plants, the client typically makes an initial
payment upon commencement of the project and progress payments at various stages
of the project. Retainages beyond the completion date, designed to insure plant
performance and compliance with specifications, are common.

     Most of the Company's contracts related to its engineering services
activities have historically been undertaken on a cost-plus basis. However, the
trend in the industry is away from this form of relatively riskless pricing,
with project owners increasingly requiring pricing alternatives that shift to
the service provider certain or all of the risk associated with cost overruns
and other service delivery inefficiencies. These alternatives include guaranteed
maximum price, fixed-price, incentive fee and other forms of "value-based"
pricing arrangements. The Company expects this trend to continue in the future,
with the result that the Company will be required to maintain and continually
improve, relative to its competitors, both the precision of its cost estimates
and the efficiency with which it delivers services. If managed properly, these
forms of pricing arrangements provide the Company with the potential for higher
margins. However, if the Company's discipline in either its cost estimates or
service efficiency declines or fails to keep pace with that of its competitors
the volume of awarded projects and their margins may be affected adversely. See
"-- Competition."

     The following table reflects the amount and approximate percentage of the
Company's combined revenues for each of the last three years, derived from each
of the Company's three basic types of contract pricing provisions:

</TABLE>

     In cases relating to the Company's engineering service projects where the
Company is responsible for equipment or materials procurement and places a
markup on the procurement costs, the Company records on its accounts the
revenues and expenses associated with the procurement services. On other
projects involving procurement services where the Company charges no mark-up on
the equipment or materials provided to its client, the revenues and expenses
associated with the Company's procurement services are not recorded on its
accounts.

     In accordance with industry practice, most of the Company's contracts are
subject to termination at the discretion of the client. Most contracts provide
for reimbursement of costs incurred and payment of fees earned by the Company
through the date of termination. Many of the Company's contracts also provide
indemnification to the client for losses and expenses incurred by the client as
a result of the Company's negligence and, in certain instances, the concurrent
negligence of the client. While the Company historically has not incurred
material losses with respect to these claims and maintains insurance in amounts
it considers adequate, no assurance can be given that the Company will not have
significant indemnification claims in the future, that claims made will not be
outside or exceed the Company's insurance coverage or that the

                                       37
<PAGE>
Company will be able to continue to obtain insurance coverage at rates it
considers reasonable. See "-- Risk Management; Litigation."

     Under certain contracts, the Company guarantees project completion by a
scheduled date or by achievement of certain acceptance and perfomance testing or
milestone levels. At December 31, 1997, the Company had underway projects
aggregating approximately $46.9 million in contract amount, which are subject to
some form of completion or performance guarantee. If the Company fails to meet
any required completion or performance requirements and is unable to remedy the
failure within the applicable cure period, the Company could incur financial
penalties in the form of liquidated damages or could be required to design or
repeat the service or repair or replace the system. See "Risk
Factors -- Completion Guarantees."

CLIENTS

     During 1997, the Company provided engineering, design, construction
management and procurement services to more than 702 industrial, commercial and
institutional clients, involving more than 1,780 projects in the private sector
and 90 projects in the public sector. The following table reflects the
approximate percentage of combined revenues derived from the Company's major
client groups for each of the last three years:

     The Company's engineering services group has many clients representing a
broad range of industries and institutions, most of whom are repeat clients, and
historically has not had a continuing dependence on any single client or any
limited group of clients. However, one or a few clients have in the past and may
in the future contribute a substantial portion of the Company's revenues in any
one year or over a period of several consecutive years due to the size of major
engineering projects. The Company's business is not necessarily dependent upon
sustaining the level of revenues contributed by particular clients in any given
year or period of consecutive years. Historically, the Company has not generated
significant revenues from governmental clients, which accounted for only
approximately $4.4 million, $4.4 million and $3.6 million of the Company's
combined revenues during 1995, 1996 and 1997, respectively. In the Company's
experience, once it begins work on a particular project, it is unlikely the
client will terminate the Company's involvement before completion of the
project, unless the project itself is cancelled or postponed. Historically, the
Company has undertaken new projects for prior clients and has provided ongoing
services to clients following completion of their projects. Nonetheless, the
Company must continually obtain new engineering projects, whether from existing
or new clients, in order to generate revenues in future years as existing
projects are completed.

     In recent years, the continuing trend among the Company's engineering
services clients and their industry counterparts toward outsourcing,
single-sourcing and downsizing has fostered the development of arrangements with
clients which are less oriented toward specified projects and more focused on
ongoing, longer-term relationships. These arrangements, often referred to as
partnering relationships or alliances, and, in some cases, sole source
contracts, vary in their scope, duration and degree of commitment. Some provide
the Company with a minimum number of work man-hours over specified periods; some
assure the Company of at least a designated percentage of the client's
requirements for engineering services at one or more locations; and some
establish the Company as the client's sole source of engineering services at a

                                       38
<PAGE>
specific location or locations. Other agreements express only a client's
non-binding preference or intent with respect to the Company and its services,
or establish a general contractual framework for what the parties expect will be
an ongoing relationship. Despite their variety, the collective effect of these
partnering relationships or alliances is to exert a stabilizing influence on the
Company's engineering services revenues. At present, the Company has some form
of partnering or alliance arrangement with several major refineries and chemical
companies. At December 31, 1997, approximately an aggregate $31.2 million of
future work under the Company's partnering or alliance contracts was considered
to be sufficiently firm for inclusion in the Company's backlog at that date. See
"-- Backlog".

     The Company's engineered systems clients include both end users, such as
drilling companies, oil and gas producers, pipelines, compressor stations,
chemical companies and processing plants, that own or operate the facilities for
which the systems are designed, and equipment manufacturers, construction
contractors and other engineering firms that incorporate the Company's control
systems into facilities and products of their own design, construction and
manufacture. In the past, the Company has undertaken only a small number of
modular processing plant projects each year, seeking out and choosing only those
which offer the greatest profit margin opportunities. As in the Company's
engineering services segment, in any given year, a small number of clients may
account for a large percentage of the engineered systems revenues for that year,
depending on the number of major projects undertaken by the Company. Though the
engineered systems segment frequently receives work from repeat clients, its
client list may vary greatly from year to year.

     No single client accounted for 10% or more of the Company's 1997 pro forma
combined revenues.

BACKLOG

     The following table sets forth the Company's combined backlog at December
31, 1996 and 1997, for each of its two major segments and by geographic regions:

                                       =========  =========

     The Company's combined backlog at December 31, 1997, most of which is
expected to be completed within the next 12 months, includes only contracts for
which the Company has received authorization to proceed with the work. Although
this backlog represents only work which is under contract, it is not necessarily
indicative of the Company's future revenues or earnings related to the
performance of the work included in backlog. The Company's contracts are subject
to standard industry cancellation provisions, including cancellation on short
notice or upon completion of designated stages. Authorizations to proceed are
for periods generally shorter than the duration of the work the Company expects
to perform for a particular client, and significant scope-of-work adjustments
are common. For certain risks associated with the Company's backlog, see "Risk
Factors -- Nature of Backlog."

FACILITIES

     For its professional, technical and administrative staff, the Company
leases 16 offices in the U.S. and foreign locations totaling approximately
358,000 square feet, and owns two office buildings in Baton Rouge, Louisiana
totaling approximately 40,500 square feet. The leases have remaining terms
ranging from one to four years and are at what the Company considers to be
commercially reasonable rental rates. The Company's principal office locations
are in Houston, Beaumont and Nederland, Texas; Baton Rouge and

                                       39
<PAGE>
Lake Charles, Louisiana; Warren and Atlantic City, New Jersey; Miami and Tampa,
Florida; Louisville, Kentucky; Al-Khobar, Riyadh and Yanbu, Saudi Arabia; and
Abu Dhabi, United Arab Emirates. The Company's Warren, New Jersey offices,
comprising approximately 90,300 square feet, are leased from entities controlled
by certain of the former stockholders of PS&S under several leases expiring in
2008.

     Engineering and assembly of the Company's control and instrumentation
systems is performed at its approximately 21,000 square foot leased facility in
Beaumont, Texas, and at its approximately 30,000 square foot owned facility in
Houston. The Beaumont property is leased from a partnership owned one-third by
each of Petrocon, Michael L. Burrow and another Petrocon shareholder, which
lease expires in 2000.

     The Company builds its modular gas processing plants in Houston, Texas at a
five-acre site, which includes approximately 33,000 square feet of owned office
and shop space and an adjacent 2,300 square foot leased paint and sandblasting
building, which is leased from a former GEI stockholder.

     The Company believes its office and other facilities are well-maintained
and adequate for the Company's existing and planned operations at each operating
location.

EMPLOYEES

     As of December 31, 1997, the Company had approximately 1,614 regular,
full-time employees, including 1,120 engineers, scientists, chemists, designers
and draftsmen, 145 construction managers, inspectors and technicians, 128
production support staff, and 221 administrative and clerical personnel. At that
date, approximately 1,605 Company employees were based in the United States, of
which approximately 400 were placed on assignment in client facilities, and
approximately 9 employees were based in foreign countries. In addition, at
December 31, 1997, PAL employed 272 foreign-based employees. The table below
shows the number of regular, full-time employees in each of the Company's
engineering segments at the dates indicated.

     The Company is not a party to any collective bargaining agreements, has not
experienced any strikes or work stoppages and believes its relationship with its
employees is good.

GOVERNMENT REGULATION

     The Company and its clients are subject to various evolving foreign,
federal, state and local laws and regulations, including those relating to the
environment, health and safety. To date, the Company has mostly benefited from
these laws and regulations and their impact on its clients, and the cost of the
Company's own compliance has not been material, but the fact that such laws and
regulations are changed frequently makes uncertain both the Company's expected
continuing benefits and costs associated with such laws and regulations. The
modification of existing laws or regulations or the adoption of new laws or
regulations affecting the Company's clients or its own operations or industry
could adversely affect the Company.

     The Company and members of its professional staff are subject to a variety
of state, local and foreign licensing, registration and other regulatory
requirements governing the practice of engineering. Company professionals are
licensed or registered in approximately 46 states and foreign jurisdictions. The
Company endeavors to be in compliance with all applicable licensing and
registration requirements, and does not believe that any failure to be in such
compliance at any given time will have a material adverse effect on its
operations or revenues. Nor does the Company believe that such licensing or
registration requirements will offer any material impediment to the Company's
proposed geographic expansion due to the prevalence of reciprocity arrangements,
the relative ease of the licensing process in most jurisdictions, and the number
and varied disciplines and qualifications of its professional staff.

RISK MANAGEMENT; LITIGATION

     In performing services for its clients, the Company could potentially be
liable for breach of contract, personal injury, property damage or negligence,
including professional errors and omissions. The Company often agrees to
indemnify its clients for losses and expenses incurred by them as a result of
the Company's negligence and, in certain instances, the concurrent negligence of
the clients. A portion of the Company's activities relate to environmental
services which involve significant risks to the Company with respect to
environmental damage, personal injury, fines and costs imposed by regulatory
agencies. Although liabilities arising from environmental regulations are more
directly applicable to the Company's clients, under certain circumstances those
regulations could impose liability on the Company, including on a joint and
several liability basis. The Company's quality control and assurance program
includes a control function to establish standards and procedures for
performance and documentation of performance project tasks, and an assurance
function to audit the control function and to monitor compliance with procedures
and quality standards. The Company maintains liability insurance for bodily
injury and third-party property damage, professional errors and omissions, and
workers compensation coverage which it considers sufficient to insure against
these risks, subject to self-insured amounts.

     The Company is, from time to time, a party to litigation arising in the
ordinary course of its business, most of which involves contract claims,
professional errors and omissions claims and claims for personal injury or
property damage incurred in connection with its operations. The Company is not
currently involved in any litigation that the Company believes will have a
material adverse effect on its financial condition or results of operations.

     No assurance can be given that the Company's insurance will be sufficient
under all circumstances to protect the Company against significant claims for
damages. The occurrence of a significant event not fully insured against could
materially and adversely affect the Company's financial condition and results of
operations. Moreover, no assurance can be given that the Company will be able to
maintain adequate insurance in the future at commercially reasonable rates or on
acceptable terms.

CLASSES OF DIRECTORS; DIRECTOR COMPENSATION

     The Board of Directors is divided into three classes. Following a
transitional period, the directors of each class will serve for three years,
with one class being elected each year at the annual stockholders' meeting.
During the transitional period, the terms of the Class I directors will expire
at the 1999 meeting, the terms of the Class II directors will expire at the 2000
meeting and the terms of the Class III directors will expire at the 2001
meeting. Classification of the Board could lengthen the time necessary to change
the composition of a majority of the members comprising the Board. In general,
at least two annual meetings of

                                       43
<PAGE>
stockholders will be necessary for stockholders to effect a change in a majority
of the members of the Board.

     Directors who are employees of the Company do not receive additional
compensation for serving as directors. Following the closing of the Offering,
each director who is not an employee of the Company initially will receive a fee
of $2,500 for each board meeting attended and $1,500 for each board committee
meeting attended and will periodically be granted options under the Incentive
Plan for the purchase of Common Stock. See "-- Incentive Plan." When the
Offering closes, each of OEI's five outside directors will be granted options to
purchase 10,000 shares of Common Stock at an exercise price per share equal to
the initial public offering price. The Company will reimburse directors for
out-of-pocket expenses incurred in attending Board of Directors or Board
committee meetings in their capacity as directors.

EXECUTIVE COMPENSATION; EMPLOYMENT AGREEMENTS

     On closing of the Offering, the Company will have employment agreements
with Messrs. Burrow, Coury, Berry, Swindler and Raiford, which provide for
annual base salaries of $300,000, $250,000, $175,000, $200,000 and $150,000,
respectively. As of the closing of the Pending Acquisitions, certain Acquired
Companies will enter into employment agreements with a total of 13 of their key
officers, including Jerry G. Gulsby, the President of GEI, William Paulus, Jr.,
Anthony J. Sartor and Philip A. Falcone, the principal stockholders and
executive officers of PS&S, Kenneth W. Castlebury, T.L. Lynn, Kenneth W. Oliver
and John W. White, the principal stockholders and executive officers of W-I, and
James W. Kerr and Jamie Ghazi, stockholders and executive officers of C&I. The
following summary of the employment agreements of these executives and key
officers does not purport to be complete and is qualified by reference to such
employment agreements, a form of which has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part. Each of these
agreements has a three-year term subject to the right of the Company to
terminate the employee's employment at any time after one year. If the
employee's employment is terminated by the Company within the first three years
without cause (as defined), the employee will be entitled to the payment of any
annual base salary and continuation of health insurance benefits for one year
following termination. Each employment agreement contains a covenant limiting
competition with the Company following the termination of employment for a
period of (i) four years from the effective date of the employment agreement if
employment is terminated for cause (as defined) or voluntarily by the executive
or (ii) six months following the termination if employment is terminated without
cause or due to disability, subject to the right of the Company, in the latter
circumstances, to extend the period of restricted competition for up to an
additional one year by continuing the executive's annual base salary and
insurance benefits for the additional year.

     The Company will also pay one-time cash bonuses in the amount of $60,000 to
each of Messrs. Coury and Swindler for their efforts and assistance in
connection with, and conditioned on the closing of, the Pending Acquisitions and
the Offering.

INCENTIVE PLAN

     The description set forth below summarizes the principal terms and
conditions of the Incentive Plan, does not purport to be complete and is
qualified in its entirety by reference to the Incentive Plan, a copy of which
has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part.

     GENERAL.  The objectives of the Incentive Plan, which was approved by the
Board of Directors and stockholders, are to attract and retain selected key
employees, consultants and outside directors, encourage their commitment,
motivate their performance, facilitate their obtaining ownership interests in
the Company (aligning their personal interests to those of the Company's
stockholders) and enable them to share in the long-term growth and success of
the Company.

     SHARES SUBJECT TO INCENTIVE PLAN.  Under the Incentive Plan, the Company
may issue Incentive Awards (as defined below) covering at any one time an
aggregate of the greater of (i) 2,000,000 shares of Common Stock and (ii) 10% of
the number of shares of Common Stock issued and outstanding on the last day of
the then preceding calendar quarter. No more than 2,000,000 shares of Common
Stock will be

                                       44
<PAGE>
available for ISOs (as defined below). As of the closing of the Pending
Acquisitions, options covering           shares of Common Stock will be
outstanding or allocated for grant and          shares of Common Stock then will
be available for subsequent Incentive Awards. The number of securities available
under the Incentive Plan and outstanding Incentive Awards are subject to
adjustments to prevent enlargement or dilution of rights resulting from stock
dividends, stock splits, recapitalization or similar transactions or resulting
from a change in applicable laws or other circumstances.

     ADMINISTRATION.  The Incentive Plan will be administered by the
compensation committee of the Board of Directors (the "Committee"). Following
the Offering, the Committee will consist solely of directors ("Outside
Directors") each of whom is (i) an "outside director" under Section 162(m) of
the Internal Revenue Code of 1986, as amended (the "Code"), and (ii) a
"non-employee director" under Rule 16b-3 under the Securities Exchange Act of
1934, as amended (the "Exchange Act"). The Committee may delegate to the chief
executive officer or other senior officers of the Company its duties under the
Incentive Plan, except with respect to any authority to grant Incentive Awards
or take other action with respect to persons who are subject to Section 16 of
the Exchange Act or Section 162(m) of the Code. In the case of an Incentive
Award to an Outside Director, the Board of Directors shall act as the Committee.
Subject to the express provisions of the Incentive Plan, the Committee is
authorized to, among other things, select grantees under the Incentive Plan and
determine the size, duration and type, as well as the other terms and conditions
(which need not be identical), of each Incentive Award. The Committee also
construes and interprets the Incentive Plan and any related agreements. All
determinations and decisions of the Committee are final, conclusive and binding
on all parties. The Company will indemnify members of the Committee against any
damage, loss, liability, cost or expenses arising in connection with any claim,
action, suit or proceeding by reason of any action taken or failure to act under
the Incentive Plan, except for any such act or omission constituting willful
misconduct or gross negligence.

     ELIGIBILITY.  Key employees, including officers (whether or not they are
directors), and consultants of the Company and non-employee directors are
eligible to participate in the Incentive Plan. A key employee generally is any
employee of the Company who, in the opinion of the Committee, is in a position
to contribute materially to the growth and development and to the financial
success of the Company.

     TYPES OF INCENTIVE AWARDS.  Under the Incentive Plan, the Committee may
grant (i) incentive stock options ("ISOs"), as defined in Section 422 of the
Code, (ii) "nonstatutory" stock options ("NSOs"), (iii) stock appreciation
rights ("SARs"), (iv) shares of restricted stock, (v) performance units and
performance shares, (vi) other stock-based awards, and (vii) supplemental
payments dedicated to the payment of income taxes (collectively, "Incentive
Awards"). ISOs and NSOs are sometimes referred to collectively herein as
"Options." The terms of each Incentive Award will be reflected in an agreement
(the "Incentive Agreement") between the Company and the participant.

     OPTIONS.  Generally, Options must be exercised within 10 years of the grant
date. ISOs may be granted only to employees, and the exercise price of each ISO
may not be less than 100% of the fair market value of a share of Common Stock on
the date of grant. The Committee will have the discretion to determine the
exercise price of each NSO granted under the Incentive Plan. To the extent the
aggregate fair market value of shares of Common Stock with respect to which ISOs
are exercisable for the first time by any employee during any calendar year
exceeds $100,000, those Options must be treated as NSOs.

     The exercise price of each Option is payable in cash or, in the discretion
of the Committee, by the delivery of shares of Common Stock owned by the
Optionee, or the withholding of shares that would otherwise be acquired on the
exercise of the Option, or by any combination of the foregoing.

     An employee will not recognize any income for federal income tax purposes
at the time an ISO is granted, or on the qualified exercise of an ISO, but
instead will recognize capital gain or loss (as applicable) upon the subsequent
sale of shares acquired in a qualified exercise. The exercise of an ISO is
qualified if a participant does not dispose of the shares acquired by the
participant's exercise within two years after the ISO grant date and one year
after such exercise. The Company is not entitled to a tax deduction as a result
of the grant or qualified exercise of an ISO.

                                       45
<PAGE>
     An optionee will not recognize any income for federal income tax purposes,
nor will the Company be entitled to a deduction, at the time an NSO is granted.
However, when an NSO is exercised, the optionee will recognize ordinary income
in an amount equal to the difference between the fair market value of the shares
received and the exercise price of the NSO, and the Company will generally
recognize a tax deduction in the same amount at the same time.

     The foregoing federal income tax information is a summary only, does not
purport to be a complete statement of the relevant provisions of the Code and
does not address the effect of any state, local or foreign taxes.

     SARS.  Upon exercise of an SAR, the holder will receive cash, shares of
Common Stock or a combination thereof, as specified in the related Incentive
Agreement, the aggregate value of which equals the amount by which the fair
market value per share of the Common Stock on the date of exercise exceeds the
exercise price of the SAR, multiplied by the number of shares underlying the
exercised portion of the SAR. An SAR may be granted in tandem with or
independently of an NSO. SARs will be subject to such terms and conditions and
will be exercisable at such times as determined by the Committee, provided, that
the exercise price per share must equal at least 100% of the fair market value
of a share of a Common Stock on the date of grant. The value of an SAR may be
paid in cash, shares of Common Stock or both in combination, as determined by
the Committee.

     RESTRICTED STOCK.  Restricted stock may be subject to substantial risk of
forfeiture, a restriction on transferability or rights of repurchase or first
refusal of the Company, as determined by the Committee. Unless otherwise
determined by the Committee, during the period of restriction, the grantee will
have all other rights of a stockholder, including the right to vote and receive
dividends on the shares.

     PERFORMANCE UNITS AND PERFORMANCE SHARES.  Performance units and
performance shares may be granted only to employees and consultants. For each
performance period (to be determined by the Committee), the Committee will
establish specific financial or non-financial performance objectives, the number
of performance units or performance shares and their contingent values, which
values may vary depending on the degree to which such objectives are met.

     OTHER STOCK-BASED AWARDS.  Other stock-based awards are awards denominated
or payable in, valued in whole or in part by reference to or otherwise related
to shares of Common Stock. Subject to the terms of the Incentive Plan, the
Committee may determine any terms and conditions of other stock-based awards,
provided that, in general, the amount of consideration to be received by the
Company shall be either (i) no consideration other than services actually
rendered or to be rendered (in the case of the issuance of shares) or (ii) in
the case of an award in the nature of a purchase right, consideration (other
than services rendered) at least equal to 50% of the fair market value of the
shares covered by such grant on the date of grant. Payment or settlement of
other stock-based awards will be in shares of Common Stock or in other
consideration related to such shares.

     SUPPLEMENTAL PAYMENTS FOR TAXES.  The Committee may grant, in connection
with an Incentive Award (except for ISOs), a supplemental payment in an amount
not to exceed the amount necessary to pay the federal and state income taxes
payable by the grantee with respect to the Incentive Award and the receipt of
the supplemental payment.

     OTHER TAX CONSIDERATIONS.  Upon accelerated exercisability of Options and
accelerated lapsing of restrictions upon restricted stock or other Incentive
Awards in connection with a Change in Control (as defined in the Incentive
Plan), certain amounts associated with such Incentive Awards could, depending
upon the individual circumstances of the participant, constitute "excess
parachute payments" under Section 280G of the Code, thereby subjecting the
participant to a 20% excise tax on those payments and denying the Company a
corresponding deduction. The limit on the deductibility of compensation under
Section 162(m) of the Code is also reduced by the amount of any excess parachute
payments. Whether amounts constitute excess parachute payments depends upon,
among other things, the value of the Incentive Awards accelerated and the past
compensation of the participant.

                                       46
<PAGE>
     Taxable compensation earned by executive officers who are subject to
Section 162(m) of the Code in respect of Incentive Awards is subject to certain
limitations set forth in the Incentive Plan generally intended to satisfy the
requirements for "qualified performance-based compensation," but no assurance
can be given that OEI will be able to satisfy these requirements in all cases,
and the Company may, in its sole discretion, determine in one or more cases that
it is in its best interest not to satisfy these requirements even if it is able
to do so.

     TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL.  Except as otherwise
provided in the applicable Incentive Agreement, if a participant's employment or
other service with the Company (or its subsidiaries) is terminated (i) other
than due to his death, Disability, Retirement or for Cause (each capitalized
term as defined in the Incentive Plan), his then exercisable Options will remain
exercisable for 60 days after such termination, (ii) by reason of Disability or
death, his then exercisable Options will remain exercisable for one year
following such termination, (iii) due to his retirement, his then exercisable
Options will remain exercisable for six months (except for ISOs, which will
remain exercisable for three months), or (iv) for Cause, all his Options will
expire at the commencement of business on the date of such termination.

     Upon a Change in Control of OEI, any restrictions on restricted stock and
other stock-based awards will be deemed satisfied, all outstanding Options and
SARs may become immediately exercisable and all the performance shares and units
and any other stock-based awards may become fully vested and deemed earned in
full, at the discretion of the Committee. These provisions could in some
circumstances have the effect of an "anti-takeover" defense because, as a
result of these provisions, a Change in Control of OEI could be more difficult
or costly.

     INCENTIVE AWARDS NONTRANSFERABLE.  No Incentive Award may be assigned, sold
or otherwise transferred by a participant, other than by will or by the laws of
descent and distribution, or be subject to any encumbrance, pledge, lien,
assignment or charge. An Incentive Award may be exercised during the
participant's lifetime only by the participant or the participant's legal
guardian.

     AMENDMENT AND TERMINATION.  The Board of Directors may amend or terminate
the Incentive Plan at any time, except that the Incentive Plan may not be
modified or amended, without stockholder approval, if such amendment would (i)
increase the number of shares of Common Stock which may be issued thereunder,
except in connection with a recapitalization of the Common Stock, (ii) amend the
eligibility requirements for employees to purchase Common Stock under the
Incentive Plan, (iii) increase the maximum limits on Incentive Awards that may
be issued to executive officers who are subject to Section 162(m) of the Code,
(iv) extend the term of the Incentive Plan or (v) decrease the authority granted
to the Committee under the Incentive Plan in contravention of Rule 16b-3 under
the Exchange Act. No termination or amendment of the Incentive Plan shall
adversely affect in any material way any outstanding Incentive Award previously
granted to a participant without his consent.

     On the closing of the Offering, the Company expects Options to purchase a
total of           shares of Common Stock will be outstanding or allocated for
grant. Of these Options, 768,384 Options represent Replacement Options
(including 2,722, 238,038, 146,734 and 153,288 options held by Messrs. Burrow,
Coury, Raiford and Swindler, respectively). These replacement options have a
weighted exercise per share of $7.68. On or prior to closing of the Offering,
additional Options to purchase shares of Common Stock will be granted or
allocated for grant to the following persons to purchase the respective number
of shares indicated: (i) Mr. Burrow (       shares); (ii) Mr. Coury, (
shares); (iii) Mr. Berry (       shares); (iv) Mr. Swindler (       shares); (v)
Mr. Raiford (     shares); (vi) Messrs. Lehmann, Forbes, Pieper, Gower and Haden
(10,000 shares each); and (vii) other employees as a group (        shares). All
these additional options will have an initial exercise price per share equal to
the initial public offering price and will become exercisable as to 25% of such
shares six months after the date the Offering closes and as to 25% of such
shares on each anniversary of that date.

EMPLOYEE STOCK PURCHASE PLAN

     The Company's Employee Stock Purchase Plan for United States employees (the
"Employee Purchase Plan") was adopted by the Board of Directors in April 1998.
A total of 300,000 shares of Common Stock

                                       47
<PAGE>
has been reserved for issuance under the Employee Purchase Plan. The Employee
Purchase Plan, which is intended to qualify under Section 423 of the Code, has
quarterly offering periods each year beginning on the first trading day on or
after January 1, April 1, July 1 and October 1, respectively, except for the
first such offering period which commences on the first trading day on or after
the effective date of the Offering and ends on the last trading day on or before
              , 1998. The Employee Purchase Plan is administered by the Board of
Directors or by a committee appointed by the Board. A United States employee is
eligible to participate if the employee is (i) customarily employed by the
Company or any participating subsidiary for at least 20 hours per week and more
than five months in any calendar year and (ii) employed by the Company or any
participating subsidiary on the effective date of the Employee Purchase Plan, or
if not employed on such effective date, has completed at least six consecutive
months of employment with the Company or any participating subsidiary. The
Employee Purchase Plan permits eligible employees to purchase Common Stock
through payroll deductions of up to 15% of an employee's compensation (including
commissions and overtime, but excluding other bonuses and incentive
compensation), up to a maximum of $25,000 for all offering periods ending within
the same calendar year. The price of stock purchased under the Employee Purchase
Plan is 90% of the lower of the fair market value of the Common Stock at the
beginning or at the end of each offering period. Employees may end their
participation at any time during an offering period, and they will be repaid
their payroll deductions to date. Participation ends automatically upon
termination of employment with the Company or any participating subsidiary.

     Rights granted under the Employee Purchase Plan are not transferable by a
participant other than by will, the laws of descent and distribution, or as
otherwise provided under the Employee Purchase Plan. The Employee Purchase Plan
provides that, in the event of a merger of OEI with or into another corporation
or a sale of substantially all of OEI's assets, the Board of Directors shall
shorten the offering period then in progress (so that employees' rights to
purchase stock under the Plan are exercised prior to the merger or sale of
assets). The Employee Purchase Plan will terminate in April 2008. The Board of
Directors has the authority to amend or terminate the Employee Purchase Plan,
except that no such action may adversely affect any outstanding rights to
purchase stock under the Employee Purchase Plan.

BONUS AWARDS; OTHER PLANS

     The 1998 bonuses for officers and key employees of the Company, if any,
will be based upon the performance standards to be established by the
Compensation Committee. The Company expects the Compensation Committee to
establish such performance standards for the remainder of 1998 following the
closing of the Offering.

     The Company has adopted or intends to adopt deferred compensation,
supplemental disability, supplemental life and retirement or other benefit or
welfare plans in which executive officers of the Company will be eligible to
participate.

     The Compensation Committee will be established on the closing of the
Offering. In the past, matters with respect to the compensation of executive
officers of OEI were determined by its Board of Directors, including those
members who serve as executive officers.

                              CERTAIN TRANSACTIONS

ORGANIZATION OF OEI

     OEI was formed in October 1997 by Petrocon's management to conduct the
Offering, simultaneously consummate the Pending Acquisitions and continue
Petrocon's successful acquisition program. OEI was initially capitalized with
$1,000 provided by Messrs. Burrow, Coury, Berry and Swindler and Equus II, in
exchange for          shares of Common Stock. Mr. Lehmann, a director of OEI, is
a director and the President of Equus II, and Mr. Forbes, also an OEI director,
is a Vice President of Equus II.

     Since October 1997, Equus II has advanced funds to OEI under a $2.5 million
short-term promissory note (the "Equus Note") for use in connection with OEI's
efforts to conduct the Offering and consummate the Pending Acquisitions. The
Equus Note bears interest at a designated prime rate plus 1/2%. At December 31,
1997, approximately $0.1 million was outstanding under the Equus Note. OEI
expects to borrow an additional $2.4 million under the Equus Note before the
Offering closes. The Company intends to repay the Equus Note in full from
proceeds of the Offering.

     Concurrently with the closing of the Offering, OEI will consummate the
Pending Acquisitions. The consideration to be paid by the Company in the Pending
Acquisitions consists of (i) approximately $27.8 million in cash, (ii) 5,053,027
shares of Common Stock and (iii) approximately $3.4 million and 654,099 shares
to be placed in escrow with respect to one of the Pending Acquisitions. In
addition, the Company will assume certain of the indebtedness of Petrocon and
the Acquired Companies (approximately $28.1 million as of December 31, 1997).

     Subject to certain adjustments described below, the following table sets
forth for Petrocon and each Acquired Company the cash and shares of Common Stock
to be paid and issued to its stockholders in the Pending Acquisitions.

     The Company will also assume and repay an aggregate of $28.1 million of
indebtedness of Petrocon and certain of the Acquired Companies ($21.8 million of
which will be repaid from proceeds of the Offering and $6.3 million of which
will be repaid from cash on hand), as follows: Petrocon -- $16.4 million; 
PS&S -- $1.9 million; GEI -- $3.6 million; W-I -- $6.1 million; and C&I -- $0.1
million. In addition, the Company will place approximately $3.4 million and
654,099 shares of Common Stock in escrow in connection with the GEI acquisition,
which will be paid to the former GEI stockholders, or returned to the Company,
depending on the future financial performance of GEI. See "The Company --
Summary of Terms of the Pending Acquisitions."

     Prior to the closing of the Pending Acquisitions, certain Acquired
Companies may make additional distributions to their stockholders of certain
assets and related liabilities with an aggregate net book value of approximately
$9.0 million.

     Pursuant to the acquisition agreements, certain stockholders of each of
Petrocon and the Acquired Companies have agreed not to compete with the Company
for a period of three years commencing on the date of closing of the Pending
Acquisitions.

     In connection with the Pending Acquisitions, OEI will grant certain
registration rights to former stockholders of Petrocon and the Acquired
Companies. OEI has also granted certain registration rights to Equus II. See
"Shares Eligible for Future Sale."

REAL ESTATE AND OTHER TRANSACTIONS

     The Company leases space in Beaumont, Texas from a partnership owned
one-third by each of Petrocon, Mr. Burrow and another Petrocon shareholder. The
lease expires in 2000 and has a present annual rental rate of approximately
$115,000.

     The Company believes the rentals paid under the lease described above
represent fair market rates.

COMPANY POLICY

     In the future, any transactions with directors, officers, employees or
affiliates of the Company are anticipated to be minimal and will, in any case,
be approved in advance by a majority of the Board of Directors, including a
majority of disinterested members of the Board of Directors.

    Mr. Lehmann and Mr. Forbes disclaim beneficial ownership of any of those
    shares.

                        SHARES ELIGIBLE FOR FUTURE SALE

     On closing of the Pending Acquisitions and the Offering,            shares
of Common Stock will be outstanding. The shares sold in the Offering (other than
to affiliates of the Company) will be freely tradable by the public. The
remaining outstanding shares of Common Stock (collectively, the "Restricted
Shares") have not been registered under the Securities Act and may be resold
publicly only following their effective registration under the Securities Act or
under an available exemption from the registration requirements of the
Securities Act, such as Rule 144. In general, under Rule 144 as now in effect,
if a minimum of one year elapses from the later of the date of acquisition of
the Restricted Shares from OEI or from an affiliate of OEI, a person (or persons
whose shares of Common Stock are aggregated), including persons who may be
deemed "affiliates" of OEI, would be entitled to sell in any three-month
period a number of Restricted Shares which does not exceed the greater of (i) 1%
of the then outstanding shares of Common Stock and (ii) the average weekly
trading volume of the Common Stock during the period of the four preceding
calendar weeks. 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, if a period
of at least two years elapses from the later of the date Restricted Shares were
acquired from OEI or the date they were acquired from an affiliate of OEI, a
stockholder who is not an affiliate of OEI at the time of sale and has not been
an OEI affiliate for at least three months before the sale would be entitled to
sell shares of Common Stock in the public market immediately, without compliance
with the foregoing Rule 144 requirements. Rule 144 does not require the same
person to hold the Restricted Shares for the applicable periods under certain
circumstances. This Rule 144 summary is not intended to be a complete
description of the Rule. The SEC has proposed amendments to Rule 144 that would,
among other things, eliminate the manner of sale requirements and revise the
notice provisions of the Rule. The SEC has also solicited comments on other
possible changes to Rule 144, including possible revisions to its one- and two-
year holding periods and its volume limitations.

     The Company has agreed not to directly or indirectly sell, offer to sell,
solicit an offer to buy, contract to sell, grant any option to purchase or
otherwise transfer or dispose of any shares of Common Stock or any security
convertible or exchangeable for Common Stock for a period of two years (the
"Lockup Period") following the date of this Prospectus, without the prior
written consent of Smith Barney Inc., except that the Company may issue Common
Stock in connection with acquisitions, pursuant to awards under the Incentive
Plan or pursuant to the exercise of warrants outstanding as of the closing of
the Offering (consisting only of the Replacement Warrants). Further, all of
OEI's officers, directors and current stockholders (including Equus II), and all
persons who acquire shares in connection with the Pending Acquisitions, have
agreed generally not to offer, sell or otherwise dispose of any of their shares
for two years following the date of this Prospectus, without the prior written
consent of Smith Barney Inc.

     OEI will enter into a registration rights agreement (the "RRA") with the
former stockholders of Petrocon and the Acquired Companies, which will provide
certain registration rights with respect to the Common Stock issued to such
stockholders in the Pending Acquisitions. The RRA will provide for a single
demand registration right, exercisable by the holders of at least 51.0% of the
shares of Common Stock initially subject to the RRA, to require the Company to
file a registration statement under the Securities Act to register the sale of
not less than 1,000,000 shares by the requesting stockholders and any other
holders of Common Stock parties to the RRA who desire to sell pursuant to such
registration statement. The demand request may not be made until           ,
     . The demand registration rights conferred by the RRA will terminate on
                 . Subject to certain conditions and limitations, the RRA will
also give its parties the right to participate in registrations by the Company
of OEI equity securities in underwritten offerings commencing on
                 . In a separate registration rights agreement with Equus II,
OEI has granted Equus II the right to demand two registrations of shares of
Common Stock, and the right to include for its own account, or for the account
of others, subject to certain exceptions, shares of Common Stock in certain
registrations in which the Company registers shares for its account.

     The RRA requires the Company to pay the costs associated with an offering
subject to the RRA, other than underwriting discounts and commissions and
transfer taxes attributable to the shares sold on behalf of

                                       52
<PAGE>
the selling stockholders. The RRA provides that the number of shares of Common
Stock that must be registered on behalf of selling stockholders is subject to
limitation if the managing underwriter determines that market conditions require
such a limitation. Pursuant to the RRA, OEI will indemnify the selling
stockholders, and the selling stockholders will indemnify OEI, against certain
liabilities in respect of any registration statement or offering covered by the
RRA.

     The Company intends to register                shares of Common Stock under
the Securities Act during 1998 for its use in connection with future
acquisitions. These shares generally will be freely tradable after their
issuance by persons not affiliated with the Company; however, sales of these
shares during the Lockup Period would require the prior written consent of Smith
Barney Inc.

     The Company intends to file a registration statement on Form S-8 under the
Securities Act to register the shares of Common Stock reserved or to be
available for issuance pursuant to the Incentive Plan and Employee Purchase
Plan. Shares of Common Stock issued pursuant to the Incentive Plan and Employee
Purchase Plan after the effective date of that registration statement generally
will be available for sale in the open market by holders who are not affiliates
of OEI and, subject to the volume and other limitations of Rule 144, by holders
who are affiliates of OEI.

                          DESCRIPTION OF CAPITAL STOCK

     OEI's authorized capital stock consists of 40,000,000 shares of Common
Stock and 1,000,000 shares of preferred stock, par value $.001 per share (the
"Preferred Stock"). At April 7, 1998,                shares of Common Stock
and no shares of Preferred Stock were issued and outstanding. On closing of the
Pending Acquisitions and the Offering,                  shares of Common Stock
(                 if the underwriters' over-allotment option is exercised in
full) will be issued, outstanding and nonassessable, and                shares
of Common Stock will then be reserved for issuance under all then outstanding
options, warrants and other rights (consisting only of Incentive Plan options
and the Replacement Warrants issued in connection with the Petrocon
acquisition). The following summary is qualified in its entirety by reference to
the Charter, which is filed as an exhibit to the Registration Statement of which
this Prospectus is a part.

COMMON STOCK

     The Common Stock possesses ordinary voting rights for the election of
directors and in respect of other corporate matters. Each share has one vote.
The Common Stock affords no cumulative voting rights, and the holders of a
majority of the shares voting for the election of directors can elect all
directors if they so choose. The Common Stock carries no preemptive rights and
is not convertible, redeemable, assessable or entitled to the benefits of any
sinking fund. The holders of Common Stock are entitled to dividends in such
amounts and at such times as may be declared by the Board of Directors out of
funds legally available for that purpose, subject to the dividend preference of
any stock ranking senior to the Common Stock, including the Preferred Stock. See
"Dividend Policy" for information regarding the Company's initial dividend
policy.

PREFERRED STOCK

     The Preferred Stock may be issued from time to time by the Board of
Directors as shares of one or more classes or series. Subject to the provisions
of the Charter and limitations prescribed by law, the Board of Directors is
expressly authorized to adopt resolutions to issue the shares, fix the number of
shares and change the number of shares constituting any series, and provide for
the powers, designations, preferences and relative, participating, optional or
other rights, and the qualifications, limitations or restrictions thereof,
including without limitation, voting powers, dividend rights (including whether
dividends are cumulative), dividend rates, terms of redemption (including
sinking fund provisions), redemption prices, conversion rights and liquidation
preferences of the shares constituting any class or series of the Preferred
Stock, in each case without any further action or vote by the holders of Common
Stock. Although OEI has no present intention to issue 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

                                       53
<PAGE>
example, 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 the transaction; or such an issuance might facilitate a business
combination by including voting rights that would supply 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. The Board of Directors could act in a manner that would discourage
an acquisition attempt or other transaction that some or 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 its then market price.
The Board of Directors does not presently intend to seek stockholder approval
before any issuance of currently authorized stock, unless otherwise required by
law or the rules of any exchange on which OEI's securities are traded.

STATUTORY BUSINESS COMBINATION PROVISION

     OEI is a Delaware corporation and is subject to Section 203 of the DGCL. In
general, Section 203 prevents an "interested stockholder" (defined generally
as a person owning 15% or more of a corporation's outstanding voting stock) from
engaging in a "business combination" (as defined) with a Delaware corporation
for three years following the date the person became an interested stockholder
unless: (i) before the person became an interested stockholder, the board of
directors of the corporation approved the transaction in which the interested
stockholder became an interested stockholder or approved the business
combination; (ii) upon consummation of the transaction that resulted in the
person becoming an interested stockholder, that person owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding stock held by directors who are also officers of the
corporation and by employee stock plans that do not permit employees to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer); or (iii) following the transaction in
which such person became an interested stockholder, the business combination was
approved by the board of directors of the corporation and authorized at a
meeting of stockholders by the affirmative vote of the holders of 66% of the
outstanding voting stock of the corporation not owned by the interested
stockholder. Under Section 203, its restrictions also do not apply to certain
business combinations proposed by an interested stockholder following the
announcement or notification of one of certain extraordinary transactions
involving the corporation and a person who had not been an interested
stockholder during the previous three years or who became an interested
stockholder with the approval of the majority of the corporation's directors, if
the extraordinary transaction is approved or not opposed by a majority of the
directors who were directors before any person becoming an interested
stockholder during the previous three years or were recommended for election or
elected to succeed such directors by a majority of such directors.

OTHER MATTERS

     Delaware law authorizes a Delaware corporation to limit or eliminate the
personal liability of its directors to the corporation and its stockholders for
monetary damages for breach of a director's fiduciary duty of care. The duty of
care requires that directors, when acting on behalf of the corporation, must
exercise an informed business judgment based on all material information
reasonably available to them. Absent the limitations authorized by Delaware law,
directors are accountable to a Delaware corporation and its stockholders in
monetary damages, for conduct constituting gross negligence in the exercise of
their duty of care. Delaware law enables a Delaware corporation to limit
available relief to equitable remedies such as injunction or rescission. The
Charter limits the liability of directors of OEI to OEI or its stockholders to
the fullest extent permitted by Delaware law. Specifically, no member of the
Board of Directors will 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 member's duty of loyalty to OEI 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 as provided in Section 174 of the DGCL or (iv)
for any transaction from which the member derived an improper personal benefit.
This Charter provision 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 OEI

                                       54
<PAGE>
and its stockholders. The Charter and bylaws provide indemnification to OEI's
officers and directors and certain other persons with respect to certain
matters, and the Company has entered into agreements with each of OEI's
directors and executive officers providing for indemnification with respect to
certain matters.

     The Charter provides that (i) stockholders may act only at an annual or
special meeting of stockholders and not by written consent and (ii) special
meetings of the stockholders can be called only by the chairman of the board,
the chief executive officer, the president or a majority of the Board of
Directors. The Charter also provides that the Board of Directors shall consist
of three classes of directors serving for staggered terms. It is currently
contemplated that approximately one-third of the Board of Directors will be
elected each year. The classified board provision could prevent a party who
acquires control of a majority of the outstanding voting stock of OEI from
obtaining control of the Board of Directors until the second annual
stockholders' meeting following the date the acquirer obtains the controlling
interest. See "Management -- Directors and Executive Officers." The Charter
provides that the number of directors shall be as determined by the Board of
Directors from time to time, but shall not be less than three. It also provides
that directors may be removed only for cause, and then only by the affirmative
vote of the holders of at least two-thirds of all outstanding voting stock. This
provision, in conjunction with the Charter provisions authorizing the Board of
Directors to fill vacant directorships, will prevent stockholders from removing
incumbent directors without cause and then filling the resulting vacancies with
their own nominees.

STOCKHOLDER PROPOSALS

     OEI's bylaws contain provisions requiring that advance notice be delivered
to OEI of any business to be brought by a stockholder before an annual meeting
of stockholders and establishing certain procedures to be followed by
stockholders in nominating persons for election to the Board of Directors.
Generally, the advance notice provisions provide that written notice must be
given to the secretary of OEI by a stockholder (i) in the event of business to
be brought by a stockholder before an annual meeting and (ii) in the event of
nominations of persons for election to the Board of Directors by any
stockholder, in each case not less than 60 nor more than 180 days prior to the
anniversary date of the immediately preceding annual meeting of stockholders
(with certain exceptions if the date of the annual meeting is different by more
than specified periods from the anniversary date). The stockholder's notice must
set forth specific information regarding the stockholder and his business or
director nominee, as described in OEI's bylaws. The foregoing summary is
qualified in its entirety by reference to OEI's bylaws, which are filed as an
exhibit to the Registration Statement of which this Prospectus is a part.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company, 40 Wall Street, New York, New York 10005.

                                  UNDERWRITING

     Upon the terms and subject to the conditions stated in the Underwriting
Agreement, each of the Underwriters named below has severally agreed to purchase
from the Company, and the Company has agreed to sell to such Underwriter, the
number of shares of Common Stock set forth opposite the name of such
Underwriter.

              UNDERWRITER                  OF SHARES

Sanders Morris Mundy Inc................

                                          ------------
          Total.........................
                                          ============

     The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock are
subject to approval of certain legal matters by their counsel and to certain
other conditions. The Underwriters are obligated to take and pay for all shares
of Common Stock offered hereby (other than those covered by the over-allotment
option described below) if any such shares are taken.

     The Underwriters, for whom Smith Barney Inc., CIBC Oppenheimer Corp. and
Sanders Morris Mundy Inc. are acting as representatives (the
"Representatives"), propose to offer part of the shares of Common Stock
directly to the public at the offering price set forth on the cover page of this
Prospectus and part of the shares to certain dealers at a price which represents
a concession not in excess of $     per share under the public offering price.
The Underwriters may allow, and such dealers may reallow, a concession not in
excess of $     per share to certain other dealers. After the initial offering
of the shares to the public, the public offering price and such concessions may
be changed by the Representatives. The Representatives of the Underwriters have
advised the Company that the Underwriters do not intend to confirm any shares to
any accounts over which they exercise discretionary authority.

     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an additional
shares of Common Stock at the price to the public set forth on the cover page of
this Prospectus, minus the underwriting discounts and commissions. The
Underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, in connection with the Offering. To the extent such
option is exercised, each Underwriter will be obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number of shares set forth opposite each Underwriter's name in the
preceding table bears to the total number of shares listed in such table.

     OEI's officers or directors when the Offering closes, its current
stockholders (including Equus II) and all persons who acquire shares of Common
Stock and receive Replacement Options and Replacement Warrants in the Pending
Acquisitions who, immediately following the Offering, collectively will
beneficially own an aggregate of at least           shares of Common Stock
(including shares issuable upon the exercise of outstanding options and warrants
exercisable within 60 days of the closing of the Offering), have agreed that for
a period of two years after the date of this Prospectus they will not, without
the prior written consent of Smith Barney Inc., directly or indirectly sell,
offer to sell, solicit an offer to buy, contract to sell, grant any option to
purchase or otherwise transfer or dispose of any shares of Common Stock, options
or warrants to acquire shares of Common Stock, or any securities exchangeable or
exercisable for or convertible into shares of Common Stock. OEI has also agreed
not to directly or indirectly sell, offer to sell, solicit an offer to buy,
contract to sell, grant any option to purchase or otherwise

                                       56
<PAGE>
transfer or dispose, or announce the offering of, or file any registration
statement under the Securities Act in respect of, any shares of Common Stock,
options or warrants to acquire shares of the Common Stock or securities
exchangeable or exercisable for or convertible into shares of Common Stock, for
a period of two years after the date of this Prospectus without the prior
written consent of Smith Barney Inc., except (i) shares of Common Stock issued
in connection with the Pending Acquisitions, (ii) shares of Common Stock issued
on the exercise of Options awarded under the Incentive Plan, the Employee
Purchase Plan or the Replacement Warrants, (iii) additional Options awarded
under the Incentive Plan and (iv) shares of Common Stock issued in connection
with future acquisitions (but not greater than an aggregate of           shares
during the first year of the two-year lock-up period), so long as, (a) in the
case of issuances described in the preceding clauses (ii) and (iii), the
recipient agrees to remain subject to the lock-up until the end of the two-year
period (or, if the recipient is an employee of the Company but is neither an
officer or director of OEI nor the holder of 5% or more of the outstanding
shares of Common Stock, until the lapse of the first 180 days of the two-year
period) and (b) in the case of issuances described in the preceding clause (iv),
the recipient agrees to remain subject to a negotiated lock-up period.

     Prior to the Offering, there has not been any public market for the Common
Stock of the Company. Consequently, the initial public offering price for the
shares of Common Stock included in the Offering has been determined by
negotiations between the Company and the Representatives. Among the factors
considered in determining such price are the history of and prospects for the
Company's business and the industry in which it competes, an assessment of the
Company's management and the present state of the Company's development, the pro
forma combined revenues and earnings of the Company, the historical revenues and
earnings of Petrocon and the Acquired Companies, the prospects for the growth of
the Company's revenues and earnings, the current state of the economy in the
United States and the current level of economic activity in the industry in
which the Company competes and in related or comparable industries, and
currently prevailing conditions in the securities in the securities markets,
including current market valuations of publicly traded companies that are
comparable to the Company.

     The Company has agreed to indemnify the Underwriters and certain related
persons against certain liabilities, including liabilities under the Securities
Act, or to contribute to payments that the Underwriters may be required to make
in respect thereof.

     The Representatives have advised the Company that, pursuant to Regulation M
under the Exchange Act, certain persons participating in the Offering may engage
in transactions, including stabilizing bids, syndicate covering transactions or
the imposition of penalty bids, which may have the effect of stabilizing or
maintaining the market price of the Common Stock at a level above that which
might otherwise prevail in the open market. A "stabilizing bid" is a bid for
or the purchase of the Common Stock on behalf of the Underwriters for the
purpose of fixing or maintaining the price of the Common Stock. A "syndicate
covering transaction" is the bid for or the purchase of the Common Stock on
behalf of the Underwriters to reduce a short position incurred by the
Underwriters in connection with the Offering. A "penalty bid" is an
arrangement permitting the Representatives to reclaim the selling concession
otherwise accruing to an Underwriter or syndicate member in connection with the
Offering if the Common Stock originally sold by such Underwriter or syndicate
member is purchased by the Representatives in a syndicate covering transaction,
and has therefore not been effectively placed by such Underwriter or syndicate
member. The Representatives have advised the Company that such transactions may
be effected on The New York Stock Exchange or otherwise and, if commenced, may
be discontinued at any time.

                                 LEGAL MATTERS

     Certain legal matters in connection with the sale of the Common Stock
offered hereby are being passed upon for OEI by Porter & Hedges, L.L.P.,
Houston, Texas, and for the Underwriters by Morgan, Lewis & Bockius LLP, New
York, New York.

        OEI INTERNATIONAL, INC. AND PETROCON AND THE ACQUIRED COMPANIES

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
                             BASIS OF PRESENTATION

     The following unaudited pro forma combined financial statements give effect
to (i) the acquisitions by OEI International, Inc. (OEI), of the outstanding
capital stock of Petrocon Engineering, Inc. and Subsidiaries (Petrocon), Paulus,
Sokolowski and Sartor Inc. (PS&S), Gulsby Engineering, Inc. and Subsidiary
(GEI), W-Industries, Inc. (W-I) and Chemical & Industrial Engineering, Inc.
(C&I) (together, the Pending Acquisitions), and related transactions and (ii)
the Offering. The Pending Acquisitions will occur simultaneously with the
closing of OEI's initial public offering (the Offering) and will be accounted
for using the purchase method of accounting. Petrocon has been identified as the
accounting acquiror for financial statement presentation purposes as its
stockholders will represent the largest voting interest within OEI.

     The unaudited pro forma combined balance sheet gives effect to the Pending
Acquisitions and related transactions, and the Offering, as if they had occurred
on December 31, 1997. The unaudited pro forma combined statements of operations
give effect to these transactions as if they had occurred on January 1, 1997.

     OEI has preliminarily analyzed the savings expected to be realized from
reductions in salaries, bonuses and certain benefits to the owners and other
known cost eliminations. To the extent the owners of Petrocon and the Acquired
Companies have contractually agreed to prospective reductions in salary,
bonuses, benefits and lease payments, these reductions and other known cost
eliminations have been reflected in the unaudited pro forma combined statements
of operations. With respect to other potential cost savings, OEI has not and
cannot quantify these savings until completion of the Pending Acquisitions. It
is anticipated that these savings will be offset by costs related to OEI's new
corporate management and by the costs associated with being a public company.
However, because these costs cannot be accurately quantified at this time, they
have not been included in the pro forma financial information of OEI.

     The pro forma adjustments are based on preliminary estimates, available
information and certain assumptions that Company management deems appropriate
and may be revised as additional information becomes available. The pro forma
financial data do not purport to represent what OEI's financial position or
results of operations would actually have been if such transactions in fact had
occurred on those dates and are not necessarily representative of OEI's
financial position or results of operations for any future period. Since
Petrocon and the Acquired Companies were not under common control or management,
historical combined results may not be comparable to, or indicative of, future
performance. The unaudited pro forma combined financial statements should be
read in conjunction with the other financial statements and notes thereto
included elsewhere in this Prospectus. See also "Risk Factors" included
elsewhere herein.

        OEI INTERNATIONAL, INC. AND PETROCON AND THE ACQUIRED COMPANIES
           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

1.  GENERAL:

     The Company is a diversified engineering company providing engineering
services and engineered systems to a broad range of industrial, commercial and
institutional clients throughout the United States and internationally. The
Company's multidisciplined expertise enables it to offer its clients total
design and engineering solutions extending from project inception through
completion, start-up and operation, within multiple industries and across
diverse geographic markets. OEI has conducted no operations to date and will
acquire Petrocon and the Acquired Companies concurrently with and as a condition
of the closing of this Offering.

     The historical financial statements reflect the financial position and
results of operations of Petrocon and the Acquired Companies' and were derived
from Petrocon and the Acquired Companies' respective financial statements where
indicated. The periods included in these financial statements for Petrocon and
the Acquired Companies are as of and for the year ended December 31, 1997. The
audited historical financial statements included elsewhere in this Prospectus
have been included in accordance with Securities and Exchange Commission (SEC)
Regulation S-X. I. Rule 3-05.

2.  ACQUISITION OF PETROCON AND THE ACQUIRED COMPANIES:

     Concurrently with and as a condition to the closing of the Offering, OEI
will acquire all of the outstanding capital stock of the Petrocon and Acquired
Companies. The acquisitions will be accounted for using the purchase method of
accounting with Petrocon being reflected as the accounting acquiror as its
stockholders will represent the largest voting interest within OEI.

     The following table sets forth the consideration to be paid (a) in cash and
(b) in shares of Common Stock to the common stockholders of Petrocon and
Acquired Companies. For purposes of computing the estimated purchase price for
accounting purposes, the value of the shares was determined using an estimated
fair value of $     per share, which is less than the initial public offering
price due primarily to restrictions on the sale and transferability of the
shares issued. The total estimated purchase price of $84.4 million for the
acquisitions is based upon preliminary estimates and is subject to certain
purchase price adjustments at and following closing.

                                                    SHARES OF
                                         CASH      COMMON STOCK

4.  UNAUDITED PRO FORMA COMBINED STATEMENTS OF OPERATIONS ADJUSTMENTS:

     (a)  Reduces compensation expense to the contractual levels the owners and
          key employees of the Petrocon and the Acquired Companies have agreed
          to receive subsequent to the Pending Acquisitions. Additionally,
          reflects the reversal of the $6.4 million non-recurring non-cash
          compensation charge by OEI related to the issuance of shares of Common
          Stock to management. The historical financial statements of OEI
          include a compensation charge representing the differences between the
          amounts paid for the shares issued to OEI's management and their
          estimated value on the date of the sale as if the Pending Acquisitions
          had occurred.

     (b)  Records goodwill amortization expense using a 40-year estimated life.

     (c)  Reduces interest expense for repayment of certain debt obligations
          which will be repaid from the net proceeds of the Offering and
          existing cash.

     (d)  Records a reduction of rent expense of $236 net of depreciation of $74
          for property to be acquired in connection with the Pending
          Aquisitions.

     (e)  Reflects the incremental provision for federal and state income taxes
          relating to the other statements of operations adjustments and for
          income taxes on S Corporation income.

     (f)  The number of shares estimated to be outstanding on completion of the
          Offering includes the following (reflects the           , 1998 stock
          split) (in thousands):

Issued to management.................

  (including escrowed shares)........        5,707

          subject to options granted under OEI's Incentive Plan which have an
          exercise price equal to the initial Offering price per share. See

                         NOTES TO FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BUSINESS ACTIVITY

     OEI International, Inc. (OEI or the Company), a Delaware corporation, was
founded on October 9, 1997. The Company is a diversified engineering company
providing engineering services and engineered systems to a broad range of
industrial, commercial and institutional clients throughout the United States
and internationally. OEI intends to acquire five engineering companies (the
Acquisitions), complete an initial public offering (the Offering) of its common
stock and, subsequent to the Offering, continue to acquire, through merger or
purchase, similar companies to expand its national and international operations.

     OEI's primary assets at December 31, 1997, are cash and deferred offering
costs. OEI has not conducted any operations, and all activities to date have
related to the Acquisitions and the Offering. Cash of $980 was generated from
the initial capitalization of the Company (see Note 2). There is no assurance
that the Acquisitions discussed below will be completed and that OEI will be
able to generate future operating revenues. Funding for the deferred offering
costs has been provided by Equus II Incorporated (Equus II). OEI is dependent
upon the Offering to fund the amounts due to Equus II, the Acquisitions and
future operations.

  INCOME TAX

     The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109.
Under this method, deferred income taxes are recorded based upon the differences
between the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
underlying assets or liabilities are recovered or settled.

  STOCK OPTIONS

     Effective September 4, 1997, the Company adopted SFAS No. 123, "Accounting
for Stock-Based Compensation." This pronouncement allows two methods of
calculating the fair market value of equity instruments issued to employees, in
accordance with Accounting Principles Board (APB) Opinion No. 25 or using an
option-pricing model. The fair market value of equity instruments issued to
employees may be calculated using an option-pricing model such as the
Black-Scholes model that takes into account, as of the grant date, the exercise
price and expected life of the equity instrument, the current price of the
underlying stock, expected dividends on the stock and the risk-free interest
rate for the expected term of the equity instrument. The Company has elected to
calculate compensation expense in accordance with APB No. 25 which calculates
compensation expense as the difference between the employee's exercise price and
the current price of the underlying stock. There were no financial statement
effects from the adoption of this pronouncement.

  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The Company enters into various types of financial instruments in the
normal course of business. The Company does not hold or issue financial
instruments for trading purposes, nor does it hold interest rate, leveraged or
other types of derivative financial instruments. The carrying amounts of the
Company's financial instruments approximate their fair values.

  USE OF ESTIMATES

     The preparation of the Company's 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
disclosures of contingent assets and liabilities at the date of the financial
statements

                            OEI INTERNATIONAL, INC.
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

2.  STOCKHOLDERS' EQUITY:

     On April 6, 1998, OEI effected a 1,828.368-for-one stock split for each
share of common stock of the Company ("Common Stock") then outstanding. In
addition, the Company increased the number of authorized shares of Common Stock
to 40,000,000 and authorized 1,000,000 shares of $.001 par value preferred
stock. The effects of the Common Stock split and the increase in the shares of
authorized Common Stock have been retroactively reflected on the balance sheet
and in the accompanying notes. In connection with the organization and initial
capitalization of OEI, the Company issued 1,218,973 shares of common stock at $1
per share to Equus II at an aggregate purchase price of $667.67.

     In October 1997, the Company issued a total of 572,831 shares of common
stock to management at an aggregate purchase price of $980.00. As a result, the
Company recorded a non-recurring, non-cash compensation charge of $6.4 million
at December 31, 1997, representing the difference between the amount paid for
the shares and the estimated fair value of the shares, which value has been
discounted from the estimated initial public offering price due primarily to
restrictions on the sale and transferability of the shares issued. The shares
issued to Equus II and members of management were issued to engage such parties
in providing services related primarily to the Company's public offering
activities, including financial advisory and other consulting services. The fair
value of such shares was based on specific factors related to the Company and
the transactions including restrictions on transferability and sale of the
shares issued and the limited vote provisions of such shares.

3.  INCENTIVE PLAN:

     In April 1998, the Company's stockholders and Board of Directors approved
the Company's Incentive Plan which provides for the granting of incentive or
nonstatutory stock options, stock appreciation rights, restricted stock,
performance units and performance shares and other stock-based awards
(collectively, "Incentive Awards") to key employees, officers, non-employee
directors and consultants to the Company. Under the Incentive Plan, the Company
may issue Incentive Awards covering at any one time an aggregate of the greater
of (i) 2,000,000 shares of Common Stock and (ii) 10% of the number of shares of
Common Stock issued and outstanding on the last day of the then preceding
calendar quarter. No more than 2,000,000 shares of Common Stock will be
available for incentive stock options.

4.  EMPLOYEE STOCK PURCHASE PLAN:

     In April 1998, the Company's Board of Directors approved the Company's
Employee Stock Purchase Plan for the United States employees (the "Employee
Purchase Plan"). A total of 300,000 shares of Common Stock has been reserved
for issuance under the Employee Purchase Plan. The Employee Purchase Plan
permits eligible employees to purchase Common Stock through payroll deductions
of up to 15% of an employee's compensation (including commissions and overtime,
but excluding other bonuses and incentive compensation), up to a maximum of
$25,000 for all offering periods ending within the same calendar year. The price
of stock purchased under the Employee Purchase Plan is 90% of the lower of the
fair market value of the Common Stock at the beginning or at the end of each
offering period. Employees may end their participation at any time during an
offering period, and they will be repaid their payroll deductions to date.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Petrocon Engineering, Inc.:

     We have audited the accompanying consolidated balance sheets of Petrocon
Engineering, Inc. (a Texas corporation), and subsidiaries as of December 31,
1996 and 1997, and the related consolidated statements of income, stockholders'
equity and cash flows for each of the three years in the period ended December
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
misstatement. 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
the Company as of December 31, 1996 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

  PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the accounts of
Petrocon Engineering, Inc., and its wholly owned subsidiaries (collectively, the
Company). All significant intercompany transactions have been eliminated in
consolidation.

  REVENUE RECOGNITION

     The Company provides a majority of its services through cost-plus
contracts. Revenues are recognized to the extent of billable rates times hours
delivered plus other reimbursable expenses incurred. Accounts receivable include
amounts currently billable per cost-plus contracts that are not billed until the
following period. Fixed-price contracts represent approximately 5%, 8% and 14%
of revenues in 1995, 1996 and 1997, respectively. Revenue on fixed-price
contracts is recognized using the percentage-of-completion method of accounting.
Methods used to measure percentage of completion consist of labor hours or costs
incurred compared to total estimated labor hours or costs or other appropriate
bases of measurement. Revisions in revenue and cost projections are recorded in
the period in which the facts requiring the revision become known. When
estimates of projected revenues and costs indicate a loss, the total estimated
loss is accrued. Contract performance incentives are included in income when
earned. Potential additional revenues on projects from claims and unapproved
change orders are not recognized until amounts may be reliably estimated and
realization is virtually certain. The asset "Costs and estimated profits in
excess of

                  PETROCON ENGINEERING, INC., AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
billings on uncompleted contracts" represents revenues recognized in excess of
amounts billed. The liability "Billings in excess of costs and estimated
profits on uncompleted contracts" represents amounts billed in excess of
revenues recognized.

  CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include certificates of deposit with maturities
of three months or less.

  INVESTMENTS

     The Company has a one-third ownership interest in PEI Investments, a Texas
joint venture. The Company uses the equity method of accounting for this
investment. In addition, the Company accounts for its 50% interest in Petrocon
Arabia Limited (PAL) by the equity method. PAL, an engineering company located
in Saudi Arabia, provides general engineering services for oil field, pipeline,
gas plants and offshore facilities as well as refinery and petrochemical plants.
Results of operations for PAL are translated at the average exchange rate for
the year.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of income.

     The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." Accordingly, in the event that facts and
circumstances indicate that property and equipment may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flow associated with the asset is
compared to the asset's carrying amount to determine if a write-down to fair
value is necessary.

     During 1997, the Company wrote off approximately $241,000 of leasehold
improvements made to a leased facility which the Company vacated prior to the
expiration of the lease term. Additionally, the Company has, during 1997,
written down to fair value certain property which the Company elected to hold
for sale. The amount of the property write-down was approximately $122,000, and
the net realizable value of the property, based on an independent appraisal, was
$275,000 at December 31, 1997. These write-downs have been included in the
accompanying consolidated statement of income for the year ended December 31,
1997.

  INCOME TAX

     The Company follows the liability method of accounting for income taxes in
accordance with SFAS No. 109, "Accounting for Income Taxes." Under this
method, deferred income taxes are recorded based upon the differences between
the financial reporting and tax bases of assets and liabilities and are measured
using the enacted tax rates and laws that will be in effect when the underlying
assets or liabilities are recovered or settled.

  STOCK OPTIONS

     The Company has adopted SFAS No. 123, "Accounting for Stock-Based
Compensation," and, as permitted, has elected to calculate compensation expense
in accordance with Accounting Principles Bulletin

<PAGE>
                  PETROCON ENGINEERING, INC., AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
Opinion No. 25 which calculates compensation expense as the difference between
the employee's exercise price and the current price of the underlying stock. See
Note 10 for the financial statement effects from the adoption of this
pronouncement.

  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The Company enters into various types of financial instruments in the
normal course of business. The Company does not hold or issue financial
instruments for trading purposes, nor does it hold interest rate, leveraged or
other types of derivative financial instruments. The carrying amounts of the
Company's financial instruments approximate their fair values.

  INTANGIBLE ASSETS AND AMORTIZATION

     Goodwill represents the excess of cost over the fair value of net tangible
assets of businesses acquired. Goodwill is being amortized on a straight-line
basis over an expected useful life of 40 years. Other intangible assets,
included in other assets, are amortized over the period expected to be benefited
(five to seven years). Amortization expense for goodwill and other intangible
assets was $1,020, $53,651 and $336,375 for 1995, 1996 and 1997, respectively.
Accumulated amortization of goodwill at December 31, 1996 and 1997, was $55,606
and $391,981, respectively. See Note 12 for amortization of cost over equity in
net assets included in the equity in earnings of PAL.

  USE OF ESTIMATES

     The preparation of the Company's financial statements in conformity with
generally accepted accounting principles, particularly in the use of the
percentage-of-completion method of accounting, requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures 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.

2.  MAJOR CUSTOMERS AND CREDIT RISK:

     A significant portion of the Company's customers are engaged in the energy
industry. This concentration of customers may impact the Company's overall
exposure to credit risk, either positively or negatively, in that customers may
be similarly affected by changes in economic and industry conditions. The
Company performs ongoing credit evaluations of its customers and does not
generally require collateral in support of its trade receivables. The Company
maintains reserves for potential credit losses, and actual losses have
historically been within the Company's expectations. Foreign sales also present
various risks, including risks of war, civil disturbances and adverse
governmental activities. Most of the Company's foreign sales are to large
international companies or are secured by letters of credit or similar
arrangements. The Company does not believe itself to be dependent to any
material degree on any single customer.

5.  LINE OF CREDIT AND DEBT:

     The Company has a line of credit with a credit limit of $13,000,000, of
which $5,085,908 and $11,641,357 was outstanding at December 31, 1996 and 1997,
respectively. The line of credit is secured by an interest in all of the
Company's accounts receivable and expires on August 8, 1999. Advances on the
credit line accrue interest at a rate equal to one-half of 1% plus the prime
rate (9.0% at December 31, 1997), and the commitment fee on the unused line of
credit is 0.25%. Interest is payable monthly. The line of credit contains
covenants pertaining to the maintenance of certain ratios, including fixed
charge coverage, specified levels of certain other items, including tangible net
worth and EBITDA, and various other covenants as specified in the loan
agreement, as amended. In March 1998, the credit limit on the line of credit was
increased to $14,000,000.

     In August 1996, the Company refinanced its long-term debt. The refinancing
paid off all long-term debt and established two term loans and a new line of
credit. Debt financing costs of approximately $145,000 were incurred in
conjunction with the refinancing. These costs are being amortized over three
years, the life of the debt agreement.

     Debt consists of the following:

     Deferred income tax provisions result from temporary differences in the
recognition of income and expenses for financial reporting purposes and for tax
purposes. The tax effects of these temporary differences, representing deferred
tax assets and liabilities, result principally from the following:

and federal net operating loss carryforwards of $317,050, $3,108,557 and
$133,685, respectively, which will expire between 1998 and 2012. Most of the
federal and all of the state net operating loss carryforwards are expected to
expire unused. The valuation allowance is due to expected expiration of net
operating loss carryforwards. During 1997, the deferred tax asset and valuation
allowance were reduced by $10,689 due to the expiration of net operating losses
that were not expected to be utilized.

8.  STOCKHOLDERS' EQUITY:

     The Company has a common stock redemption agreement whereby, upon a
stockholder's employment termination, divorce or desire to sell, the Company has
right of first refusal to purchase the stock held by such stockholder. Upon the
death or disability of a stockholder, the Company is obligated to purchase the
stock held by such stockholder subject to certain limits as set forth by the
Company's amended and restated stockholders' agreement. The purchase price per
share is at fair market value, as determined by the Company's board of
directors, in its good faith, and as reasonably acceptable to the stockholder.

     In 1996, the Company issued 65,000 shares of common stock valued at $4.44
per share in connection with the acquisition of TE&C (see Note 15) and awarded a
stock bonus to management of 23,039 shares valued at $4.44 per share.

     In 1997, the Company issued 536,943 shares of common stock valued at $7.82
per share in connection with the acquisition of AEI (see Note 15).

9.  REDEEMABLE PREFERRED STOCK:

     The Company has authorized 3,000,000 shares of $.3333 par value preferred
stock, which may be divided into one or more series as determined by the board
of directors. The board is authorized to fix and determine the relative rights
and preferences of each series as to dividend rate, redemption, liquidation
preferences, sinking fund provision, convertibility and voting rights. As
described below, the board has established one series of redeemable preferred
stock consisting of 675,168 shares.

     The Company's Series A convertible preferred stock (Series A) was issued
for the purpose of acquiring PAL Series A is convertible into common shares at a
specified conversion ratio based upon a conversion price of $3.33 per share, and
the stock has a liquidation preference based upon a stated value of $4.44 per
share plus the greater of a valuation increment of 12% per annum compounded from
August 31, 1992, or the increment that would have occurred had the shares been
converted to common shares. The Series A shares have full voting rights
determined by the specified conversion ratio. Stockholders may demand redemption
of up to one-sixth of their shares on September 30, 1996, and an additional
one-sixth every six months thereafter until March 31, 1999. Such redemption
rights are cumulative for any amounts not previously redeemed. The redemption
price is equal to the stated value of $4.44 per share plus a redemption premium
computed as a 12% annualized compound rate of return on the stated value from
August 31, 1992, through the redemption date.

     During such time as any shares of Series A are outstanding, the Company may
not declare or pay any dividend on or otherwise acquire or retire for value any
shares of common stock, except as required under the stock redemption agreement
described above. As of December 31, 1997, the Company has charged accretion
toward the redemption value in the aggregate amount of $1,774,785 to retained
earnings and increased the redeemable preferred stock by the same amount.

     In August 1996, the Company redeemed 463,592 shares of its Series A at
$4.44 per share plus 12% per annum as provided in the stock agreement. In August
1997, the remaining 154,531 of the Series A shares were redeemed by the Company
in exchange for (a) cash of $939,463, (b) the issuance of 106,306 shares of
common stock and (c) the issuance of options to purchase 135,998 shares of
common stock of the Company for a price of $4.44 per share. At December 31,
1997, there are no shares of Series A outstanding.

10.  EMPLOYEE BENEFIT PLANS:

     Employees of the Company may participate in a 401(k) savings plan, whereby
the employees may elect to make contributions pursuant to a salary reduction
agreement upon meeting age and length-of-service requirements. The plan also
provides for discretionary contributions by the Company, as determined by the
board of directors. Under the plan, contributions to the 401(k) plan will be
made in the name of each participating employee in direct proportion to the
employee's 401(k) contribution. Contributions of $266,000 and $220,000 are
included in accrued expenses for the years ended December 31, 1996 and 1997,
respectively. No contributions were made related to the year ended December 31,
1995.

     The Company and its employees contribute to a health plan that is
self-insured by the Company up to $60,000 per claim and approximately $2,300,000
in the aggregate.

     The Company has a nonqualified stock option plan that provides for the
issuance of options up to 1,200,000 shares of the Company's common stock. The
exercise price per share at the date of grant is equal to the fair market value
of the Company's common stock; therefore, no compensation expense is recognized.
Vesting of the options is generally as follows: one-third after one year,
two-thirds after two years and all after three years. Other vesting schedules
can be followed. Some of the options granted during 1996 and 1997 vest 10% at
grant date, 10% at January 1 of the year following grant and 10% annually
thereafter until fully vested. Another option granted during 1997 vests 16.67%
at January 1, 1998, and is fully vested in six years. Options are canceled upon
termination of employment and lapse 10 years after grant. A summary of stock
option activity is as follows:

     The summary above does not include 135,998 options issued in consideration
for redemption of Series A preferred shares (see Note 9).

     Stock-based compensation costs, as calculated under SFAS No. 123, would
have reduced pretax income by approximately $357,533 and $47,301 in 1996 and
1997, respectively, if the fair values of the options granted in those years had
been recognized as compensation expense on a straight-line basis over the
vesting period of the grant. For the purposes of SFAS No. 123, the fair market
value of the options granted during 1996 and 1997 used a risk-free interest rate
of 6.8% and 5.8%, respectively, an expected life of 10 years and expected
dividends of 0%. The pro forma effect on net income for 1996 and 1997 may not be
representative of the pro forma effect on net income in future years because it
does not take into consideration pro forma compensation expense related to
grants made prior to 1995.

11.  RELATED-PARTY TRANSACTIONS:

     The Company leases office space from PEI Investments, a Texas joint
venture, of which the Company and an officer each own a one-third interest.
Rental paid under these leases was $105,632 for 1995, 1996

approximately $115,000. The Company is contingently liable as a guarantor for a
PEI Investments bank loan. The principal balance was $288,838 and $229,916 at
December 31, 1996 and 1997, respectively.

     During 1995, 1996 and 1997, the Company provided services to PAL which
totaled $176,521, $56,216 and $33,083, respectively, in revenue. A receivable of
$1,381 and $3,158 for these services was outstanding at December 31, 1996 and

owned by members of Company management, in the amount of $400,000 and $200,000
at December 31, 1996 and 1997, respectively.

12.  PETROCON ARABIA LIMITED:

13.  DISCONTINUED OPERATIONS:

     On October 19, 1995, the board of directors approved a resolution to
discontinue all operations of Petrocon Plant Services, Inc. (PPS), PCR and
Petrocon Instrument and Electrical, Inc. (PIE), except for the PCR and PPS
inspection operations. The related financial results are reported as

     For the period from October 19, 1995, through December 31, 1995, the
discontinued operations had a net loss of $286,705.

14.  COMMITMENTS AND CONTINGENCIES:

  LITIGATION

     The Company is involved in legal actions arising in the ordinary course of
business. Management does not believe the outcome of such legal actions will
have a material adverse effect on the Company's financial position or results of
operations.

  INSURANCE

     The Company carries a broad range of insurance coverage, including general
and business auto liability, commercial property, workers' compensation and a
general umbrella policy. The Company has not incurred significant claims or
losses in excess of insurance recoveries.

  EMPLOYMENT AGREEMENTS

     The Company has employment agreements with its executive officers, the
terms of which expire at various times through October 2001. Such agreements
provide for minimum salary levels, adjusted annually for co
st-of-living changes,
as well as for incentive bonuses that are payable if specified management goals
are attained. The aggregate commitment for future salaries at December 31, 1997,
excluding bonuses, was approximately $4,400,000.

15.  ACQUISITIONS:

     Effective July 1, 1996, the Company acquired all outstanding shares of TE&C
in exchange for 65,000 shares of Company stock valued at $4.44 per share.
Additional consideration given for TE&C included assumption of outstanding
liabilities by the Company. The combination was accounted for using the purchase
method. The total purchase price of approximately $1,206,000 resulted in
$689,000 of goodwill which is being amortized over 40 years using the
straight-line method. The Company also signed an employment agreement with
TE&C's sole stockholder that includes the right to additional shares of the
Company's common stock based on continued employment with the Company. For the
years ended December 31, 1996 and 1997, $18,315 and $24,420, respectively, of
compensation expense was recognized by the Company in relation to 11,000
additional shares to be issued under this agreement. TE&C's sole stockholder
also received commissions based on the gross billings of TE&C through December
31, 1997, and these amounts were accounted for as compensation expense in the
period earned.

     Effective October 17, 1996, the Company acquired all outstanding shares of
RPM for approximately $1,859,000 in cash and stock warrants for 525,386 shares
of the Company's stock at $6.50 per share. The

combination was accounted for using the purchase method and resulted in
approximately $1,843,556 of goodwill that is being amortized over 40 years using
the straight-line method. The warrants have an exercise price of $6.50 and an
exercise period from October 17, 1996, through October 17, 2003. RPM's
stockholders will receive additional compensation based on the earnings of RPM
through December 31, 2001. The additional compensation will be accounted for as
additional goodwill to be amortized over the remaining goodwill amortization
period when the required earnings levels are achieved. The Company also signed
three- and five-year employment agreements with two of RPM's stockholders. As of
December 31, 1997, approximately $955,781 of additional consideration had been
earned and accounted for as additional goodwill.

     Effective February 1, 1997, a wholly owned subsidiary of the Company merged
with AEI in exchange for cash of $4,500,000 and 536,943 shares of Company stock
valued at $7.82 per share. The combination was accounted for using the purchase
method, and the total purchase price of $8,700,000 resulted in approximately
$6,266,000 of goodwill, which is being amortized over 40 years using the
straight-line method. The Company also signed four-year employment agreements
with certain of the former officers of AEI. Pro forma information assuming that
this acquisition had taken place as of January 1, 1997, has not been presented
due to the insignificance of the results of operations of AEI for the one month
ended January 31, 1997.

     The results of operations of companies acquired are included in the
accompanying consolidated statements of income from their respective acquisition
dates.

16.  EXPORT SALES:

     Export sales were approximately $13,100,000, $15,500,000 and $24,100,000
for the years ended December 31, 1995, 1996 and 1997, respectively. Such sales
were in South America, Europe, Africa and the Middle East and the Far East.

17.  SUBSEQUENT EVENTS:

     In April 1998, the Company and its stockholders entered into a definitive
agreement with OEI providing for the acquisition of the Company by OEI.

     Concurrently with the acquisition, the Company will enter into agreements
with PEI Investments to lease land and buildings used in the Company's
operations for a negotiated amount and term.

To the Board of Directors
Paulus, Sokolowski and Sartor, Inc.
Warren, New Jersey

     We have audited the accompanying balance sheets of Paulus, Sokolowski and
Sartor, Inc. as of December 31, 1997 and 1996 and the related statements of
operations, changes in shareholders' equity and cash flows for each of the three
years in the period ended December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Paulus, Sokolowski and
Sartor, Inc. as of December 31, 1997 and 1996, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1997 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  a.  COMPANY PROFILE

     The Company, which is located in Warren, New Jersey, was established in
1962 to provide comprehensive consulting engineering services, including
studies, reports, and design and field inspections, in the areas of structural
engineering, civil engineering, mechanical and electrical engineering (including
HVAC systems), geology, geophysics, foundation design, site selection,
environmental studies, earth and rock structures, soil and foundation, air
quality control, water quality control, noise control, and solid waste disposal.
The Company conducts its business predominantly in New Jersey and New York.

     The Company and its shareholders intend to enter into a definitive
agreement with OEI International, Inc. ("OEI") pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of OEI common stock concurrently with the consummation of the initial
public offering (the "Offering") of the common stock of OEI.

  b.  PROPERTY AND EQUIPMENT

     Property and equipment are recorded at cost. Depreciation and amortization
are calculated using the straight-line and accelerated methods over the
estimated useful lives of the assets.

     Leasehold improvements are capitalized and amortized over the lesser of the
life of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statement of operations.

     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of." Accordingly, in
the event that facts and circumstances indicate that property and equipment may
be impaired, an evaluation of recoverability would be performed. If an
evaluation is required, the estimated future undiscounted cash flows associated
with the asset is compared to the asset's carrying amount to determine if a
write-down to market value is necessary. Adoption of this standard did not have
a material effect on the financial position or results of operations of the
Company.

  c.  REVENUE RECOGNITION

     The Company provides a majority of its services through cost-plus-markup
contracts. Revenues are recognized to the extent of billable rates times hours
delivered plus materials expense incurred. Fixed priced contracts represent
approximately 24.8 percent of the Company's revenues in 1997 and approximately
19.7 percent of revenues in 1996. Revenue on fixed priced contracts is accrued
through the recognition of projected revenues and costs on a percentage-of-
completion basis. Methods used to measure percentage of completion consist of
labor hours or costs incurred compared to total estimated labor hours or costs
or other appropriate bases of measurement. Revisions in revenue and cost
projections are recorded in the period in which the facts which require the
revision become known. When estimates of projected revenues and costs indicate a
loss, the total estimated loss is accrued. Contract performance incentives are
included in income when earned. Potential additional revenues on projects from
claims and unapproved change orders are not recognized until amounts may be
reliably estimated and realization is virtually certain.

     The balance billed but not paid by customers pursuant to retainage
provisions in contracts will be due upon completion of the contracts and
acceptance by the customer. Based on the Company's experience with similar
contracts in recent years, the retention balance will be billed and collected in
the upcoming fiscal year.

  d.  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The Company enters into various types of financial instruments in the
normal course of business. The Company does not hold or issue financial
instruments for trading purposes nor does it hold interest rate, leveraged or
other types of derivative financial instruments. The carrying amounts of the
Company's financial instruments approximate their fair values.

  e.  INCOME TAXES

     The Company elected by unanimous consent of its shareholders to be taxed
under the provisions of Subchapter S of the Internal Revenue Code. Under those
provisions, the Company does not pay Federal corporate income taxes on its
taxable income. Instead, the shareholders are liable for individual Federal
income taxes on their respective shares of the Company's taxable income. The
Company will terminate its S Corporation status concurrent with the effective
date of the offering.

     Deferred income taxes reflect temporary differences between financial
reporting and state income tax reporting of revenues and expenses. The principal
differences arise from the reporting of income and expenses under the accrual
method of accounting for financial statement purposes versus the modified
accrual method for income tax purposes. These deferred taxes are classified in
the balance sheet as current.

  f.  CONCENTRATION OF CREDIT RISK

     Financial instruments that are potentially subject to concentrations of
credit risk are cash and accounts receivable. The Federal Deposit Insurance
Corporation insures each of the Company's bank accounts up to a maximum of
$100,000 in each bank. Uninsured bank balances amounted to $57,168 at December
31, 1997.

     At December 31, 1997, one customer accounted for approximately 24% of
accounts receivable. As of the date of this report, approximately $434,000 had
been collected.

  g.  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
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the period.
Actual results could differ from those estimates.

  h.  RECLASSIFICATION

     Certain amounts in the financial statement have been reclassified to
conform to the current year's presentation.

2.  PROPERTY AND EQUIPMENT

     The following is a summary of property and equipment at December 31:

6.  COMMITMENTS AND CONTINGENCIES

  a.  LITIGATION

     During 1995 a suit was filed against the Company and other defendants. With
respect to the Company, the suit alleges design deficiencies. The Company's
responsibility for issues raised in the suit is minimal and this matter is
covered by the Company's professional liability insurance policy. The possible
loss, if any, is not determinable at this time. However, management expects that
this suit will not have a material effect on the Company's financial status.

     In addition, the Company is involved in legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  b.  INSURANCE

     The Company carries a broad range of insurance coverage, including general
and business auto liability, commercial property, worker's compensation and a
general umbrella policy. The Company has not incurred significant claims or
losses on any of its insurance policies.

  c.  LEASES

     The Company is the lessee under three long-term building leases and various
equipment leases with related entities. The controlling interests of the lessors
are the same as the controlling interests of the Company.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     On December 31, 1995, the Company entered into new building leases with its
related lessors which reflect current market conditions and expire in 2011 and
2017. In addition to base rents the leases require the Company to pay all
operating costs plus real estate tax increases over base year amounts pertaining
to the buildings. In connection with the previously existing leases, the lessors
forgave rents due in the amount of $1,124,500 in 1995. Furthermore, the lessors
reduced the 1995 total base rent from $2,065,616 to $1,371,532. The Company
predominantly leases the buildings for their offices and subleases certain space
to third parties.

     The equipment leases expire in various years through 2001 and require
monthly rent based upon the current prime rate plus six percentage points as
adjusted by Summit Bank.

     The following is a summary of rental expense of all operating leases:

statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Gulsby

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BUSINESS ACTIVITY

     Gulsby Engineering, Inc. (the Company), a Texas corporation, and its
subsidiary, Gulsby International Engineers, Limited (a U.S. Virgin Islands
Foreign Sales Corporation), are engineering, systems and construction management
contractors, servicing industrial customers with primary focus in the process
industries--oil, chemical and petrochemical products. The Company has operated
primarily in the domestic markets of Texas, Louisiana, Oklahoma and New Mexico.
The Company focus in 1996 and 1997 has changed to the foreign market (98% and
94% of revenues for 1996 and 1997, respectively).

     The Company and its stockholders intend to enter into a definitive
agreement with OEI International, Inc. (OEI), pursuant to which all outstanding
shares of the Company's common stock will be exchanged for cash and shares of
OEI common stock concurrent with the consummation of the initial public offering
(the Offering) of the common stock of OEI.

  PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
and its subsidiary. All significant intercompany transactions and balances have
been eliminated.

  REVENUE RECOGNITION

     The Company provides a majority of its services through fixed-price
contracts. Revenue on fixed-price contracts is recognized on the
percentage-of-completion method measured by the percentage of costs incurred to
total estimated costs for each contract. Revisions in revenue and cost
projections are recorded in the period in which the facts requiring the revision
become known. When estimates of projected revenues and costs indicate a loss,
the total estimated loss is accrued. Potential additional revenues on projects
from claims and unapproved change orders are not recognized until amounts may be
reliably estimated and realization is virtually certain. The asset "Costs and
estimated profits in excess of billings on uncompleted contracts" represents
revenues recognized in excess of amounts billed. The liability "Billings in
excess of costs and estimated profits on uncompleted contracts" represents
amounts billed in excess of revenues recognized.

  CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include certificates of deposit with maturities
of three months or less.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of income.

     The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." Accordingly, in the event that facts and
circumstances indicate that property and equipment may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset is
compared to the asset's carrying amount to determine if

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
a write-down to market value is necessary. Adoption of this standard did not
have a material effect on the financial position or results of operations of the
Company.

  INCOME TAX

     The Company follows the liability method of accounting for income taxes in
accordance with SFAS No. 109. Under this method, deferred income taxes are
recorded based upon the differences between the financial reporting and tax
bases of assets and liabilities and are measured using the enacted tax rates and
laws that will be in effect when the underlying assets or liabilities are
recovered or settled.

  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The Company enters into various types of financial instruments in the
normal course of business. The Company does not hold or issue financial
instruments for trading purposes, nor does it hold interest rate, leveraged or
other types of derivative financial instruments. The carrying amounts of the
Company's financial instruments approximate their fair values.

  USE OF ESTIMATES

     The preparation of the Company's financial statements in conformity with
generally accepted accounting principles, particularly in the use of the
percentage-of-completion method of accounting, requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures 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.

2.  PROPERTY AND EQUIPMENT:

     Property and equipment consist of the following:

8.  COMMITMENTS AND CONTINGENCIES:

  LITIGATION

     The Company and its stockholder were party to a suit in 1989 as defendants
against a customer. The suit sought reimbursement from the Company of amounts
paid by the customer in settlement with another general contractor in a patent
infringement suit. In 1991, a summary judgment against the Company for
approximately $1.6 million plus interest was rendered. The judgment accrues
simple interest at 10% from September 29, 1989, through the date of judgment
(October 21, 1991) and thereafter at the rate of 10% per annum compounded
annually until paid. The accompanying statements of income include accruals of
interest at the stated rate. No payments on the judgment have been made at this
time.

     The Company is involved in various other legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.

  INSURANCE

     The Company carries a broad range of insurance coverage, including general
and business, auto liability, commercial property, workers' compensation and a
general umbrella policy. The Company has not incurred significant claims or
losses on any of its insurance policies.

  OTHER COMMITMENTS

     The Company contributed $40,152 into a trust during 1996 on behalf of its
employees for a potential profit sharing plan. A plan has not been adopted as of
December 31, 1997.

9.  EXPORT SALES:

     Export sales were approximately $2,800,000, $19,900,000 and $17,900,000,
for the years ended December 31, 1995, 1996 and 1997, respectively. Such sales
were in South America, Europe, Africa and the Middle East.

10.  EVENTS SUBSEQUENT TO DATE OF REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
     (UNAUDITED):

     In April 1998, the Company and its stockholder entered into a definitive
agreement with OEI, providing for the acquisition of the Company by OEI. The
definitive agreement provides that the advances to stockholder (Note 6) and
accrued legal judgement (Note 8) will be paid from the proceeds of the sale of
the stockholder's shares under the agreement.

     Concurrently with the acquisition, the Company will enter into agreements
with the stockholder to lease facilities used in the Company's operations for a
negotiated amount and term.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To W-Industries, Inc.:

     We have audited the accompanying balance sheets of W-Industries, Inc. (a
Texas corporation), as of December 31, 1996 and 1997, and the related statements
of income, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of W-Industries, Inc., as of
December 31, 1996 and 1997, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1997, in conformity

                         NOTES TO FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BUSINESS ACTIVITY

     W-Industries, Inc. (the Company), a Texas corporation, is an engineering,
systems and construction management contractor, servicing industrial customers
with primary focus in the process industries -- oil, chemical and petrochemical.
W-Industries, Inc., primarily operates in Houston, Texas.

     The Company and its stockholders intend to enter into a definitive
agreement with OEI International, Inc. (OEI), pursuant to which all outstanding
shares of the Company's common stock will be exchanged for cash and shares of
OEI common stock concurrent with the consummation of the initial public offering
(the Offering) of the common stock of OEI.

  REVENUE RECOGNITION

     The Company generally provides its services under cost-plus contracts.
Revenues are recognized to the extent of billable rates times hours delivered
plus materials expense incurred. The Company reflects the costs of materials and
equipment as revenues which are reimbursable to the Company when it is
responsible for the engineering specification, procurement and management of
such cost components on behalf of the customer. The asset "Costs and estimated
profits in excess of billings on uncompleted contracts" represents revenues
recognized in excess of amounts billed.

  CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include certificates of deposit with maturities
of three months or less.

  INVENTORY

     Inventories consist of stainless steel tube fittings, valves and
accessories held for use in the course of business and are stated at the lower
of cost or market.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost, and depreciation is computed
using an accelerated method of depreciation.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of income.

     The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." Accordingly, in the event that facts and
circumstances indicate that property and equipment may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset is
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect on
the financial position or results of operations of the Company.

  INCOME TAX

     The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company is not subject to taxation for federal
purposes. Under S Corporation status, the stockholders report their shares of
the Company's taxable earnings or losses in their personal tax returns. The
Company will terminate its S Corporation status concurrently with the effective
date of the Offering.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The Company enters into various types of financial instruments in the
normal course of business. The Company does not hold or issue financial
instruments for trading purposes, nor does it hold interest rate, leveraged or
other types of derivative financial instruments. The carrying amounts of the
Company's financial instruments approximate their fair values.

  USE OF ESTIMATES

     The preparation of the Company's financial statements in conformity with
generally accepted accounting principles, particularly in the use of contract
accounting, requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosures 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.

2.  PROPERTY AND EQUIPMENT:

     Property and equipment consist of the following:

                                                                DECEMBER 31,

To Chemical & Industrial Engineering, Inc.:

     We have audited the accompanying balance sheets of Chemical & Industrial
Engineering, Inc. (a Kentucky corporation), as of December 31, 1996 and 1997,
and the related statements of income, stockholders' equity and cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Chemical & Industrial
Engineering, Inc., as of December 31, 1996 and 1997, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  BUSINESS ACTIVITY

     Chemical & Industrial Engineering, Inc. (the Company), a Kentucky
corporation, is an engineering and systems procurement management contractor,
servicing industrial customers with primary focus in the process industries -
oil, chemical, petrochemical and food products. Chemical & Industrial
Engineering, Inc., primarily operates in Kentucky.

     The Company and its stockholders intend to enter into a definitive
agreement with OEI International, Inc. (OEI), pursuant to which all outstanding
shares of the Company's common stock will be exchanged for cash and shares of
OEI common stock concurrent with the consummation of the initial public offering
(the Offering) of the common stock of OEI.

  REVENUE RECOGNITION

     The Company provides a majority of its services through cost-plus
contracts. Revenues are recognized to the extent of billable rates times hours
delivered plus materials expense incurred. The Company does not reflect the
costs of materials and equipment as revenues which are reimbursable to the
Company when it is responsible for the engineering specification, procurement
and management of such cost components on behalf of the customer. For the three
years ended December 31, 1995, 1996 and 1997, these amounts were $4,395,384,
$4,803,742 and $8,329,277, respectively. Fixed-price contracts represent
approximately 30% of the Company's revenues in 1996 and approximately 18% of
revenues in 1997. Revenue on fixed-price contracts are recognized on the
percentage-of-completion method measured by the percentage of costs incurred to
total estimated costs for each contract. Revisions in revenue and cost
projections are recorded in the period in which the facts requiring the revision
become known. When estimates of projected revenues and costs indicate a loss,
the total estimated loss is accrued. Potential additional revenues on projects
from claims and unapproved change orders are not recognized until amounts may be
reliably estimated and realization is virtually certain. The asset "Costs and
estimated profits in excess of billings on uncompleted contracts" represents
revenues recognized in excess of amounts billed. The liability "Billings in
excess of costs and estimated profits on uncompleted contracts" represents
amounts billed in excess of revenues recognized.

  CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include short-term cash investments with
maturities of three months or less.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of income.

     The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of." Accordingly, in the event that facts and
circumstances indicate that property and equipment may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset is
compared to the asset's carrying amount to determine if

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
a write-down to market value is necessary. Adoption of this standard did not
have a material effect on the financial position or results of operations of the
Company.

  INCOME TAX

     The Company follows the liability method of accounting for income taxes in
accordance with SFAS No. 109. Under this method, deferred income taxes are
recorded based upon the differences between the financial reporting and tax
bases of assets and liabilities and are measured using the enacted tax rates and
laws that will be in effect when the underlying assets or liabilities are
recovered or settled.

  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The Company enters into various types of financial instruments in the
normal course of business. The Company does not hold or issue financial
instruments for trading purposes, nor does it hold interest rate, leveraged or
other types of derivative financial instruments. The carrying amounts of the
Company's financial instruments approximate their fair values.

  USE OF ESTIMATES

     The preparation of the Company's financial statements in conformity with
generally accepted accounting principles, particularly in the use of the
percentage-of-completion method of accounting, requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures 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.

2.  PROPERTY AND EQUIPMENT:

     Property and equipment consist of the following:

4.  DEBT:

  LINE OF CREDIT

     The Company has a line of credit of $1,500,000, which was unused at
December 31, 1996 and 1997. The line of credit is secured by an interest in all
the Company's accounts receivable, contract rights and equipment and expires on
June 15, 1998. Advances on the line of credit accrue interest at a rate equal to
prime (8.5% at December 31, 1997). Interest is payable quarterly. Management
believes the line of credit can be renewed upon expiration.

     The line of credit contains covenants requiring the maintenance of a
borrowing base equal to the aggregate of 50% of the Company's net carrying value
of equipment plus 80% of the Company's then-current accounts receivable less
than 90 days old, and various other covenants as specified in the loan
agreement, as amended. The Company is in compliance with these covenants at
December 31, 1996 and 1997.

  NOTES PAYABLE FOR STOCK REDEMPTIONS

     Notes payable consist of amounts due to 12 terminated employees for stock
redemptions at book value at the date of termination. All notes payable have
maturities of one year from redemption (currently all are due in 1998) and bear
interest ranging from 8.25% to 8.5%. The Company paid interest of $49,757 and
$15,124 related to this debt for the years ended December 31, 1996 and 1997,
respectively.

5.  LEASES:

     The Company leases office space under an operating lease agreement which
expires in June 1999. Rent expense was $257,887, $302,176 and $366,308 for the
years ended December 31, 1995, 1996 and 1997, respectively.

     The Company leases vehicles for certain key members of management which
expire 1998-2000. The lease payments under these vehicle leases were
approximately $5,437, $19,471 and $16,124 for the years ended December 31, 1995,
1996 and 1997, respectively.

     Deferred income tax provisions result from temporary differences in the
recognition of income and expenses for financial reporting purposes and for tax
purposes. The cumulative effects of these temporary differences represent
deferred tax assets and liabilities and relate principally to the following:

7.  STOCKHOLDERS' EQUITY:

     An employee is eligible to invest upon board-of-director approval in the
voting shares of the Company upon becoming a full-time, benefited employee with
a total continuous service of one year. Nonvoting stock is restricted to
full-time employees. Redemption of shares is mandatory upon employee
termination, change in employment status or death of employee. Issuance and
redemption price of stock is based on (a) the price last fixed by the board of
directors as the stock price or (b) the book value (defined as total
stockholders' equity divided by the total shares outstanding) per share,
whichever is larger. Book value per share at December 31, 1997, is $62.25. Stock
is canceled upon redemption.

8.  EMPLOYEE BENEFIT PLANS:

     Employees of the Company may participate in a 401(k) plan, whereby the
employees may elect to make contributions pursuant to a salary reduction
agreement upon meeting age and length-of-service requirements. The plan provides
for the Company to match 50% of the first 6% contributed by each employee. Total
contributions by the Company under this plan were $132,895, $160,427 and
$165,345 during 1995, 1996 and 1997, respectively.

9.  RELATED-PARTY TRANSACTIONS:

     At December 31, 1997, the Company had advanced $27,083 to OEI in expenses
related to compliance with the letter-of-intent agreement with OEI dated
November 1997. These expenses are on behalf of the stockholders and are included
in the prepaid expenses. The current intent is for the monies advanced by the
Company to be reimbursed by the stockholders upon the consummation of the
Offering.

10.  SIGNIFICANT CUSTOMERS AND VENDORS:

     Significant customers and vendors are those that account for greater than
10% of the Company's revenues and expenses, respectively. During the year ended
December 31, 1995, two customers accounted for 50% and 13% of the Company's
total revenues. Receivables outstanding from these customers represented 16% and
6% of the Company's trade receivables at December 31, 1995. For the year ended
December 31, 1996, two customers accounted for 47% and 20% of total revenues.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law permits a corporation
to indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that he is or was a director, officer, employee or agent of the corporation or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against expenses, judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action. In an action brought to obtain a judgment in the corporation's favor,
whether by the corporation itself or derivatively by a stockholder, the
corporation may only indemnify for expenses, including attorney's fees, actually
and reasonably incurred in connection with the defense or settlement of such
action, and the corporation may not indemnify for amounts paid in satisfaction
of a judgment or in settlement of the claim. In any such action, no
indemnification may be paid in respect of any claim, issue or matter as to which
such person shall have been adjudged liable to the corporation except as
otherwise approved by the Delaware Court of Chancery or the court in which the
claim was brought. In any other type of proceeding, the indemnification may
extend to judgments, fines and amounts paid in settlement, actually and
reasonably incurred in connection with such other proceeding, as well as to
expenses.

     The statute does not permit indemnification unless the person seeking
indemnification has acted in good faith and in a manner he reasonably believed
to be in, or not opposed to, the best interests of the corporation and, in the
case of criminal actions or proceedings, the person had no reasonable cause to
believe his conduct was unlawful. The statute contains additional limitations
applicable to criminal actions and to actions brought by or in the name of the
corporation. The determination as to whether a person seeking indemnification
has met the required standard of conduct is to be made (1) by a majority vote of
the directors who are not parties to such action, suit or proceeding, even
though less than a quorum, or (2) if there are no such directors, or if such
directors so direct, by independent legal counsel in a written opinion, or (3)
by the stockholders.

                                      II-1
<PAGE>
     OEI's Certificate of Incorporation and Bylaws require OEI to indemnify its
directors and officers to the fullest extent permitted under Delaware law. OEI's
Certificate of Incorporation limits the personal liability of a director to the
corporation or its stockholders to damages for breach of the director's
fiduciary duty.

     OEI has not purchased insurance on behalf of its directors and officers
against certain liabilities that may be asserted against, or incurred by, such
persons in their capacities as directors or officers of the registrant, or that
may arise out of their status as directors or officers of the registrant,
including liabilities under the federal and state securities laws. OEI has
entered into indemnification agreements to indemnify its directors and executive
officers to the maximum extent permitted under Delaware law.

     The Underwriting Agreement provides for indemnification of the directors
and officers of the Company in certain circumstances.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     The following table reflects sales by OEI of unregistered securities within
the past three years. Share amounts have been adjusted for the       -for-one
stock split effected on                 , 1998. Except as otherwise disclosed,
the issuances by OEI of the securities sold in the transactions referenced below
were not registered under the Securities Act, pursuant to the exemption
contemplated in Section 4(2) thereof, for transactions not involving a public
offering. No underwriter was involved in the transactions and no commissions
were paid. The consideration for which the shares of Common Stock were sold, all
of which was payable in cash, is indicated below:

ITEM 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes to provide to the
Underwriters, at the closing specified in the Underwriting Agreement,
certificates representing the shares of Common Stock offered hereby in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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 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

                                      II-3
<PAGE>
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

     The undersigned registrant hereby undertakes that:

          (1)  For the purposes of determining any liability under the
     Securities Act of 1933, the information omitted from the form of prospectus
     filed as a part of this registration statement in reliance upon Rule 430A
     and contained in a 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.

          (2)  For the purpose of determining any liability under the Securities
     Act of 1933, 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.

        authority to execute and deliver this Agreement and each other
        Transaction Document to which the Stockholder is a party and to perform
        the Stockholder's obligations in this Agreement and in all other
        Transaction Documents to which the Stockholder is a party. This
        Agreement constitutes, and each such other Transaction Document, when
        executed in the Stockholder's individual capacity and delivered by the
        Stockholder, will constitute, the legal, valid and binding obligation of
        the Stockholder, enforceable against the Stockholder in accordance with
        its terms, except as their enforceability may be (i) limited by any
        applicable bankruptcy, insolvency, reorganization, moratorium or similar
        laws affecting the enforcement of creditors' rights generally and (ii)
        subject to general principles of equity (regardless of whether
        enforceability is considered in a proceeding in equity or at law). If
        the Stockholder is an Entity, the Stockholder has, in accordance with
        all applicable Governmental Requirements and its Charter Documents,
        obtained all approvals and taken all actions necessary for the
        authorization, execution, delivery and performance by the Stockholder of
        this Agreement and the other Transaction Documents to which the
        Stockholder is a party. If the Stockholder is acting otherwise than in
        his individual capacity (whether as an executor or a guardian or in any
        other fiduciary or representative capacity), all actions on the part of
        the Stockholder and all other Persons (including any court) necessary
        for the authorization, execution, delivery and performance by the
        Stockholder of this Agreement and the other Transaction Documents to

        entitled, by reason of the Company's Charter Documents or the
        Governmental Requirements of the Company's Organization State or for any
        other reason, to vote to approve or disapprove the consummation of the
        Merger, has voted, or has granted an irrevocable proxy to
        representatives of OEI to vote, all the shares of Company Capital Stock
        owned by him and entitled to a vote or votes on that matter, in any one
        or more of the manners prescribed or permitted by the Company's Charter
        Documents or the Governmental Requirements of the Company's Organization
        State, whichever are controlling, to approve this Agreement and the
        consummation of the Merger and the other transactions contemplated by
        this Agreement.

(b) breach or constitute a default under any agreement or instrument (other than
Guarantees, if any, listed on Schedule 8.05) to which the Stockholder is a party
or by which the Stockholder or any of the shares of Company Capital Stock owned
by the Stockholder is bound, (c) result in the creation or imposition of, or
afford any Person the right to obtain, any Lien upon any of the shares of
Company Capital Stock owned by the Stockholder (or upon any revenues, income or
profits of the Stockholder therefrom) or (d) if the Stockholder is an Entity,

Stockholder's obligations under any Transaction Document or (b) seeks (i) to
prevent or delay the consummation by the Stockholder of the transactions
contemplated by this Agreement to be consummated by the Stockholder or (ii)
Damages in connection with any consummation by the Stockholder of the
transactions contemplated by this Agreement.

        Section 3.05. NO BROKERS. The Stockholder has not, directly or
indirectly, in connection with this Agreement or the transactions contemplated

statutory or contractual preemptive or other right of any kind (including any
right of first offer or refusal) to acquire any shares of Company Capital Stock
or OEI Common Stock or (b) hereby irrevocably waives each such right of that
type the Stockholder has or may have.

        securities or blue sky laws, no Governmental Approvals are required to

        enforcement against the Company of its obligations thereunder or the
        effectuation of the Merger and the other transactions contemplated
        thereby.

transactions contemplated hereby will violate, breach or constitute a default
under any agreement or instrument described in Section 4.03 of the Disclosure
Statement, no act or omission by the Company or any of the Company Subsidiaries
has occurred, and to the knowledge of the Company, the Company Subsidiaries and
the Stockholders, no other condition or state of facts exists, or, with the
giving of notice or the lapse of time or both, would exist, which (a) entitles
any holder of any outstanding Indebtedness, or any Guaranty not constituting
Indebtedness, of any of the Company and the Company Subsidiaries, or a
representative of the holder, to accelerate the maturity, or require a mandatory
prepayment of that Indebtedness or Guaranty, or affords the holder or its

Person, and does not control, directly or indirectly through any Person or

        Section 4.07. CAPITAL STOCK OF THE COMPANY AND THE COMPANY SUBSIDIARIES.
All the issued and outstanding shares of Capital Stock of each of the Company
and the Company Subsidiaries have been duly authorized and validly issued in
accordance with the applicable Governmental Requirements of their issuer's
Organization State and Charter Documents and are fully paid and nonassessable.
Neither the Company nor any Company Subsidiary has issued or sold any shares of
its outstanding Capital Stock in breach or violation of (a) any applicable
statutory or contractual preemptive rights, or any other rights of any kind
(including any rights of first offer or refusal), of any Person or (b) the terms
of any of its Derivative Securities which then were outstanding. Except as
accurately set forth in Section 4.07 of the Disclosure Statement, no Person has,
otherwise than solely by reason of that Person's right, if any, to vote shares
of the Capital Stock of the Company or any Company Subsidiary it holds (to the
extent those shares afford their holder any voting rights) any right to vote on
any matter with the holders of Capital Stock of the Company or any Company
Subsidiary.

        Section 4.08. TRANSACTIONS IN CAPITAL STOCK. Except as accurately set
forth in Section 4.08 of the Disclosure Statement: (a) the Company has no fixed
or contingent obligation to purchase,


                                       20

redeem or otherwise acquire or reacquire any of its equity securities or any
interests therein or to pay any dividend or make any distribution in respect
thereof, and (b) no transaction has been effected, and no action has been taken,
respecting the equity ownership of either the Company or any Company Subsidiary,
in either case in contemplation of the transactions described in this Agreement.

        Section 4.09. NO BONUS SHARES. Except as accurately set forth in Section
4.09 of the Disclosure Statement, no outstanding share of Capital Stock of the
Company was issued for less than its fair market value at the time of its
issuance or was issued in exchange for any consideration other than cash.

        Section 4.10. PREDECESSOR STATUS; ETC. Section 4.10 of the Disclosure
Statement accurately lists all the legal and assumed names of all predecessor
companies for the past five years of the Company and each Company Subsidiary,
including the names of any Entities from which the Company previously acquired
material assets. Except as accurately disclosed in Section 4.10 of the
Disclosure Statement, the Company has not been a Subsidiary or division of
another corporation or a part of an acquisition that was later rescinded.

        Section 4.11. RELATED PARTY AGREEMENTS. Except as set forth in Schedule
4.11, each Related Party Agreement in effect on the date of this Agreement will
have been terminated as of the IPO Closing Date, and no Related Party Agreement
will exist then or thereafter.

        Section 4.12. LITIGATION. Except as accurately disclosed in Section 4.12
of the Disclosure Statement, no Litigation is pending or, to the knowledge of
the Company, any Company Subsidiary or any Stockholder, threatened to which the
Company or any Company Subsidiary is or, to the knowledge of the Company, any
Company Subsidiary or the Stockholders, may become a party.

        Section 4.13. FINANCIAL STATEMENTS; DISCLOSURE.

               (a) FINANCIAL STATEMENTS. The Financial Statements (including in
        each case the related schedules and notes) delivered to OEI by the
        Company present fairly, in all material respects, the financial position
        of the Company (or the consolidated financial position of the Company
        and the consolidated Company Subsidiaries, if any) at the respective
        dates of the balance sheets included therein and the results of its
        operations (or their consolidated operations, as the case may be) and
        its cash flows (or their consolidated cash flows, as the case may be)
        for the respective periods set forth therein and have been prepared in
        accordance with GAAP. As of the date of each balance sheet included in
        all previously delivered Financial Statements, neither the Company nor
        any Company Subsidiary then had any outstanding Indebtedness to any
        Person or any liabilities of any kind (including contingent obligations,
        Tax assessments or forward or long-term commitments), or any unrealized
        or anticipated loss, which in the aggregate then were Material to the
        Company and required by GAAP to be reflected in those Financial
        Statements or in the notes related thereto, which were not so reflected.

               untrue statement of a material fact or omit to state a material
               fact necessary in order to make the statements made therein, in
               the light of the circumstances under which the statements were
               made, not misleading; and

                      (ii) all financial budgets and projections that have been
               or are hereafter from time to time prepared by the Company or any

               projections referred to in this clause (ii) are derived from

               of future results based on reasonable assumptions of the
               Company's management made at the time of their preparation, and
               that there can be no assurance that the budgets or projections
               will be obtained or maintained or that actual results will not be
               different from those budgeted or projected).

        Compensation Plans (each, a "PLAN") (i) is in substantial compliance
        with all applicable


                                       32

        provisions of ERISA and the Code, as well as with all other applicable
        Governmental Requirements, and (ii) has been administered, operated and

               (b) QUALIFICATION. All Plans that are intended to qualify under
        Section 401(a) of the Code (the "QUALIFIED PLANS") are so qualified and
        have been determined by the IRS to be so qualified (or application for
        determination letters have been timely submitted to the IRS). The
        Company has provided OEI with true, complete and correct copies of the
        current plan determination letters, most recent actuarial valuation
        reports, if any, most recent Form 5500, or, as applicable, Form
        5500-C/R, filed with respect to each Qualified Plan and most recent
        trustee or custodian report. To the extent that any Qualified Plans have
        not been amended to comply with applicable Governmental Requirements,
        the remedial amendment period permitting retroactive amendment of these
        Qualified Plans has not expired and will not expire within 120 days
        after the Effective Time. All reports and other documents required to be
        filed with any governmental agency or distributed to plan participants
        or beneficiaries (including annual reports, summary annual reports,

        filed or distributed.

               (c) NO PROHIBITED TRANSACTIONS, ETC. None of the Stockholders,
        any Plan or the Company or any Company Subsidiary has engaged in any
        Prohibited Transaction. No Plan has incurred an accumulated funding
        deficiency, as defined in Section 412(a) of the Code and Section 302(a)
        of ERISA, and no circumstances exist under which the Company or any
        Company Subsidiary could have any liability (including being subject to
        any statutory Lien to secure payment of any such liability), to the PBGC
        under Title IV of ERISA or to the IRS for any excise tax or penalty with
        respect to any Plan maintained or contributed to by the Company or any
        of its ERISA Affiliates. Further:

                      (i) there have been no terminations, partial terminations
               or discontinuances of contributions to any Qualified Plan without
               a determination by the IRS that such action does not adversely
               affect the tax-qualified status of that plan;

                      (ii)   no Termination Event has occurred;

                      (iii) no Reportable Event has occurred with respect to any
               Plan which was not properly reported;

                      (iv) the valuation of assets of any Qualified Plan, as of
               the Effective Time, will equal or exceed the actuarial present
               value of all "BENEFIT LIABILITIES" (within the meaning of Section
               4001(a)(16) of ERISA) under that plan in accordance with the
               assumptions contained in the Regulations of the PBGC governing
               the funding of terminated defined benefit plans;


                                       33
<PAGE>
                      (v) with respect to Plans qualifying as "GROUP HEALTH
               PLANS" under Section 4980B of the Code or Section 607(l) or 609
               of ERISA and related regulations (relating to the benefit
               continuation rights imposed by "COBRA" or qualified medical child
               support orders), the Company and each Company Subsidiary have
               complied in all material respects with all reporting, disclosure,
               notice, election and other benefit continuation and coverage
               requirements imposed thereunder as and when applicable to those
               plans, and neither the Company nor any Company Subsidiary has
               incurred (or will incur) any liability or is (or will be) subject
               to any loss, assessment, excise tax penalty, loss of federal
               income tax deduction or other sanction, arising on account of or
               in respect of any failure by the Company or any Company
               Subsidiary, at any time prior to the Effective Time, to comply
               with any such federal or state benefit continuation or coverage
               requirement, which is capable of being assessed or asserted
               before or after the Effective Time against the Company, any
               Company Subsidiary, the Surviving Corporation or OEI with respect
               to any of those group health plans;

                      (vi) the Financial Statements as of the Current Balance
               Sheet Date reflect the approximate total pension, medical and
               other benefit liability for all Plans, and no material funding
               changes or irregularities are reflected thereon which would cause
               those Financial Statements to be not representative of prior
               periods;

                      (vii) neither the Company nor any Company Subsidiary has
               incurred liability under Section 4062 of ERISA;

                      (viii) there are no investigations or audits of any Plan
               by any Governmental Authority which are pending or, to the
               knowledge of the Company and the Stockholders, threatened, and
               there have been no such investigations or audits that have been
               concluded that resulted in any liability of the Company or any
               Company Subsidiary that has not been fully discharged; and

                      (ix) neither the Company nor any Company Subsidiary has
               participated in any voluntary compliance or self-correction
               program established by the IRS, or entered into any closing
               agreement with the IRS with respect to the form or operation of
               any Plan.

               (d) MULTIEMPLOYER PLANS. Except as set forth in Section 4.27(d)
        of the Disclosure Statement, neither the Company nor any Company
        Subsidiary, and no ERISA Affiliate of any of them, is, or at any time
        during the six-year period ended on the date of this Agreement was,
        obligated to contribute to a Multiemployer Plan. Neither the Company nor
        any Company Subsidiary, and no ERISA Affiliate of any of them, has made

               (e) CLAIMS AND LITIGATION. Except as accurately set forth in
        Section 4.27(e) of the Disclosure Statement, no Litigation or claims
        (other than routine claims for benefits) are pending or, to the
        knowledge of the Company, threatened against, or with respect to, any of
        the Plans or with respect to any fiduciary, administrator or sponsor
        thereof (in their capacities as such), or any party-in-interest thereof.

               (f) EXCISE TAXES, DAMAGES AND PENALTIES. No act, omission or
        transaction has occurred which would result in the imposition on the
        Company or any Company Subsidiary of (i) breach of fiduciary duty
        liability damages under Section 409 of ERISA, (ii) a civil penalty
        assessed pursuant to Section 502 of ERISA or (iii) any excise tax under
        applicable provisions of the Code with respect to any Plan.

               (g) VEBA WELFARE TRUST. Any trust funding a Plan which is
        intended to be exempt from federal income taxation pursuant to Section
        501(c)(9) of the Code, satisfies the requirements of that section and
        has received a favorable determination letter from the IRS regarding the
        Plan's exempt status and has not, since receipt of the most recent
        favorable determination letter, been amended or operated in a way that
        would adversely affect its exempt status.

        Section 4.28. TAXES.

               (a) Each of the following representations and warranties in this
        Section 4.28 is qualified to the extent set forth in Section 4.28 of the
        Disclosure Statement.

               (b) All Returns required to be filed with respect to any Tax for
        which any of the Company and the Company Subsidiaries is liable have
        been duly and timely filed with the appropriate Taxing Authority, and
        each such Return correctly reflects the Tax liability and all other
        information required to be reported thereon. Each Tax shown to be
        payable on each such Return has been paid, each Tax payable by the
        Company or a Company Subsidiary by assessment has been timely paid in
        the amount assessed, and adequate reserves have been established on the
        consolidated books of the Company and the Company Subsidiaries for all
        Taxes for which any of the Company and the Company Subsidiaries is
        liable, but the payment of which is not yet due. Neither the Company nor
        any Company Subsidiary is, or ever has been, liable for any Tax payable
        by reason of the income or property of a Person other than the Company
        or a Company Subsidiary. Each of the Company and the Company
        Subsidiaries has timely filed true, correct and complete declarations of
        estimated Tax in each jurisdiction in which any such declaration is
        required to be filed by it. No Liens for Taxes exist upon the assets of
        the Company or any Company Subsidiary except Liens for Taxes which are
        not yet due. Neither the Company nor any Company Subsidiary is, or ever
        has been, subject to Tax in any jurisdiction outside of the United
        States. No Litigation with respect to any Tax for which the Company or
        any Company Subsidiary is asserted to be liable is pending or, to the
        knowledge of the Company or any Stockholder, threatened, and no basis
        which the Company or any Stockholder believes to be valid exists on
        which any


                                       35
<PAGE>
        claim for any such Tax can be asserted against the Company or any
        Company Subsidiary. There are no requests for rulings or determinations
        in respect of any Taxes pending between the Company, or any Company
        Subsidiary, and any Taxing Authority. No extension of any period during
        which any Tax may be assessed or collected and for which the Company or
        any Company Subsidiary is or may be liable, and no extension of the time
        within which the Company or any Company Subsidiary must file any Return,
        has been granted to, or requested from, any Taxing Authority. Neither
        the Company nor any Company Subsidiary is or has been a party to any tax
        allocation or sharing agreement. All amounts required to be withheld by
        any of the Company and the Company Subsidiaries and paid to governmental
        agencies for income, social security, unemployment insurance, sales,
        excise, use and other Taxes have been collected or withheld and paid to
        the proper Taxing Authority. The Company and each Company Subsidiary
        have made all deposits required by law to be made with respect to
        employees' withholding and other employment Taxes.

               (c) Neither the Company nor any Stockholder is a "foreign
        person," as that term is referred to in Section 1445(f)(3) of the Code.

               (d) The Company has not filed a consent pursuant to Section 341
        (f) of the Code or any comparable provision of any other tax statute and
        has not agreed to have Section 341 (f)(2) of the Code or any comparable
        provision of any other Tax statute apply to any disposition of an asset.
        No asset of the Company or of any Company Subsidiary is subject to any
        provision of applicable law which eliminates or reduces the allowance
        for depreciation or amortization in respect of that asset below the
        allowance generally available to an asset of its type. No accounting
        method changes of the Company or of any Company Subsidiary exist or are
        proposed or threatened which could give rise to an adjustment under
        Section 481 of the Code.

        Section 4.29. GOVERNMENT CONTRACTS. Except as accurately set forth in
Section 4.29 of the Disclosure Statement, neither the Company nor any Company
Subsidiary is a party to any governmental contract subject to price
redetermination or renegotiation.

except as accurately set forth in Section 4.30 of the Disclosure Statement, none
of the following has occurred with respect to the Company or any Company

        Effective Time;

        Members and Affiliates;

        or Affiliate thereof, provided that the Company or a Company Subsidiary
        may negotiate and adjust bills in the course of good faith disputes with
        customers in a manner consistent with past practice, if the adjustments
        are (i) included in the Supplemental Information provided OEI pursuant
        to Section 6.07 or (ii) do not exceed $25,000 in the aggregate;

               (h) any plan, agreement or arrangement granting any preferential

               (b) Each of the Company and the Stockholders hereby (i) waives
        every right, if any, the Governmental Requirements of the Company's
        Organization State afford the Company or Stockholders to require the
        Company's directors (or their equivalents if the Company is not a

        liability he might otherwise have to the Company or any Stockholders but

        Section 6.06. NOTIFICATION OF CERTAIN MATTERS. The Stockholders and the
Company shall give prompt notice to OEI of (a) the existence or occurrence of
each condition or state of facts which becomes known to them and which will or
reasonably could be expected to cause any representation or warranty of the
Company or any Stockholder contained herein to be untrue or incorrect in any
material respect at or prior to the Closing or on the IPO Closing Date and (b)
any material failure of any Stockholder or the Company to comply with or satisfy
any covenant, condition or agreement


                                       46
<PAGE>
to be complied with or satisfied by that Person hereunder. OEI shall give prompt
notice to the Company of (a) the existence or occurrence of each condition or
state of facts which will or reasonably could be expected to cause any
representation or warranty of OEI or Newco contained herein to be untrue or
inaccurate at or prior to the Closing or on the IPO Closing Date and (b) any
material failure of OEI or Newco to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder. The
delivery of any notice pursuant to this Section 6.06 shall not be deemed to (a)
modify the representations or warranties herein of the party delivering that
notice, or any other party, which modification may be made only pursuant to
Section 6.07, (b) modify the conditions set forth in Article VII or (c) limit or
otherwise adversely affect the remedies available hereunder to the party
receiving that notice.

        Section 6.07. SUPPLEMENTAL INFORMATION. Each of the Company and the
Stockholders agrees that, with respect to its representations and warranties
contained in this Agreement, it will have the continuing obligation until the
Closing to provide OEI promptly with such additional supplemental Information
(collectively, the "SUPPLEMENTAL INFORMATION"), in the form of (a) amendments to
then existing Schedules or Sections of the Disclosure Statement or (b)
additional Schedules or Sections of the Disclosure Statement, as would be
necessary, in the light of the circumstances, conditions, events and states of
facts then known to the Company or any Stockholder, to make each of those
representations and warranties true and correct in all material respects as of
the Closing and on the IPO Closing Date. For purposes only of determining
whether the conditions to the obligations of OEI and Newco which are specified
in Sections 7.04(a)(ii)(A) and 7.04(b)(ii) have been satisfied, and not for any
purpose under Article IX, the Schedules and the Disclosure Statement as of the
Closing and on the IPO Closing Date shall be deemed to be the Schedules and the
Disclosure Statement as of the date hereof as amended or supplemented by the
Supplemental Information provided to OEI prior to the Closing pursuant to this
Section 6.07; PROVIDED, HOWEVER, that if the Supplemental Information so
provided discloses the existence of circumstances, conditions, events or states
of facts which, in any combination thereof, (a) have had a Material Adverse
Effect on the Company which was not reflected in the determination of the Merger
Consideration or (b) in the judgment of OEI (which shall be conclusive for
purposes of this Section 6.07 and Article XII, but not for any purpose of
Article IX), are having or will have a Material Adverse Effect on the Company or
the Surviving Corporation, as the case may be, OEI will be entitled either (i)
to terminate this Agreement pursuant to Section 12.01(a)(iv) or (ii) to treat as
OEI Indemnified Losses for all purposes of Article IX (which treatment will not
prejudice the right of any Stockholder under Article IX to contest Damage Claims
made by OEI in respect of those OEI Indemnified Losses) all Damages to the
Company or the Surviving Corporation which are attributable to the
circumstances, conditions, events and states of facts first disclosed herein
after the date hereof in the Supplemental Information; and PROVIDED FURTHER,
HOWEVER, that if the circumstances, conditions, events or states of facts
disclosed in the Supplemental Information and having or judged to have in the
future such a Material Adverse Effect (A) have not resulted from a breach by the
Company or the Stockholders of any of their covenants set forth in Article VI or
elsewhere in this Agreement and (B) do not indicate that any representation or
warranty of the Stockholders and the Company made in Articles III and IV shall
have been untrue or inaccurate at the date of this Agreement, then OEI shall

                                 INDEMNIFICATION

        Section 9.02. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All the
provisions of this Agreement will survive the Closing and the Effective Time
notwithstanding any investigation at any time made by or on behalf of any party
hereto or the provision of any Supplemental Information pursuant to Section
6.07, provided that the representations and warranties set forth in Articles IV,
V and VI and in any certificate delivered in connection herewith with respect to
any of those representations and warranties will terminate and expire two years
after the IPO Closing Date, except as follows: (a) the representations and
warranties of the Stockholders which relate expressly or by necessary
implication to Taxes or ERISA will survive until the expiration of the
applicable statutes of limitations (including all periods of extension and
tolling); (b) the representations and warranties of the Stockholders which
relate expressly or by necessary implication to the environment or Environmental
Laws will survive for a period of three years form the Effective Time; and (c)
the representations and warranties of OEI and the Company will terminate and
expire at the Effective Time. After a representation and warranty has terminated
and expired, no claim for indemnification will or may be sought on the basis of
that representation and warranty by any Person who would have been entitled
pursuant to this Article IX to indemnification on the basis of that
representation and warranty prior to its termination and expiration, provided
that, in the case of each representation and warranty that will terminate and
expire as provided in this Section 9.02, no claim presented in writing for
indemnification pursuant to this Article IX on the basis of that representation
and warranty prior to its termination and expiration will be affected in any way
by the termination and expiration.

        Section 9.03. INDEMNIFICATION OF OEI INDEMNIFIED PARTIES.

               (a) Subject to the applicable provisions of Sections 9.02 and
        9.07, the Stockholders covenant and agree that they, jointly and
        severally, will indemnify, protect and hold harmless each OEI
        Indemnified Party, and, solely with respect to clause (iii) of this
        Section 9.03(a), the Underwriters from and after the Effective Time,
        from and against all Damages that arise from, are based on or relate or
        otherwise are attributable to (i) any breach of the representations and
        warranties of the Stockholders or the Company set forth herein (other
        than in Article III) or in certificates delivered in connection herewith
        (other than in respect of certificates relating only to the
        representations and warranties in Article III), (ii) any nonfulfillment
        of any covenant or agreement on the part of the Stockholders or the
        Company under this Agreement, (iii) any liability under the Securities
        Act, the Exchange Act or other applicable Governmental Requirement which
        arises out of or is based on (A) any untrue statement of a material fact
        relating to the Company and the Company Subsidiaries, or any of them,
        which is (1) provided to OEI or its counsel, or the Underwriters and
        their counsel, by the Company or the Stockholders and (2) contained in
        any preliminary prospectus relating to the IPO, the Registration
        Statement or any prospectus forming a part thereof, or any amendment
        thereof or supplement thereto, or (B) any omission or alleged


                                       56
<PAGE>
        omission to state therein a material fact relating to the Company and
        the Company Subsidiaries, or any of them, required to be stated therein
        or necessary to make the statements made therein, in the light of the
        circumstances under which they were made, not misleading, and which is
        not provided to OEI or its counsel by the Company or the Stockholders
        (each such Damage Claim and each Damage Claim described in Section
        9.03(b) being an "OEI INDEMNIFIED LOSS").

               (b) Each Stockholder, severally and not jointly with any other
        Person, covenants and agrees that he will indemnify, protect and hold
        harmless each OEI Indemnified Party, and, solely with respect to clause
        (iii) of this Section 9.03(a), the Underwriters from and after the
        Effective Time, from and against, and hold each OEI Indemnified Party
        harmless from and in respect of, all Damage Claims that arise from, are
        based on or relate or otherwise are attributable to (i) any breach of
        the representations and warranties of that Stockholder solely as to that
        Stockholder set forth in Article III or in certificates delivered by
        that Stockholder and relating to those representations and warranties,
        (ii) any nonfulfillment of any several, and not joint and several,
        agreement on the part of that Stockholder under this Agreement or (iii)
        any liability under the Securities Act, the Exchange Act or other
        applicable Governmental Requirement which arises out of or is based on
        (A) any untrue statement or alleged untrue statement of a material fact
        relating solely to that Stockholder which is (1) provided to OEI or its
        counsel, or the Underwriters and their counsel, by that Stockholder and
        (2) contained in any preliminary prospectus relating to the IPO, the
        Registration Statement or any prospectus forming a part thereof, or any
        amendment thereof or supplement thereto, or (B) any omission or alleged
        omission to state therein a material fact relating solely to that
        Stockholder required to be stated therein or necessary to make the
        statements made therein, in the light of the circumstances under which
        they were made, not misleading, and which is not provided to OEI or its
        counsel, or the Underwriters and their counsel, by that Stockholder.

               (c) Notwithstanding anything to the contrary contained herein,
        the amount of any Damages sustained by any Indemnified Party shall be
        determined only after giving credit for the amount of the net monetary
        benefit received by such Indemnified Party from any insurance carrier
        with respect to any policy of insurance (not including any amounts the
        Indemnified Party is required to pay with respect to deductibles or to
        reimburse to such insurer), resulting from or attributable to, the
        event, occurrence, state of facts, actions or other circumstance causing
        or giving rise to such Damages.

               (d) The Underwriters shall be deemed third party beneficiaries of
        the indemnification obligations of the Stockholders set forth in
        paragraphs (a) and (b) of this Section 9.03, with respect to the matters
        specified therein as to which they are to be indemnified. The
        Stockholders agree to execute such documents as the Underwriters may
        reasonably request to confirm the Stockholders' indemnification
        obligations to the Underwriters.

        Section 9.04. INDEMNIFICATION OF STOCKHOLDER INDEMNIFIED PARTIES. OEI
covenants and agrees that it will indemnify each Stockholder Indemnified Party
against, and hold each Stockholder Indemnified Party harmless from and in
respect of, all Damage Claims (that arise from, are based on or relate or
otherwise are attributable to (i) any breach by OEI or Newco of their
representations and warranties set forth herein or in their certificates
delivered to the Company or the Stockholders in connection herewith, (ii) any
nonfulfillment of any covenant or agreement on the part of OEI or Newco under
this Agreement (each such Damage Claim being a "STOCKHOLDER INDEMNIFIED LOSS");
or (iii) any liability under the Securities Act, the Exchange Act or other
applicable Governmental Requirement which arises out of or is based on (A) any
untrue statement or alleged untrue statement of a material fact relating to OEI,
Newco or any of the Other Founding Companies contained in any preliminary
prospectus relating to the IPO, the Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto, or (B)
any omission or alleged omission to state therein a material fact relating to
OEI, Newco or any of the Other Founding Companies, or any of them, required to
be stated therein or necessary to make the statements made therein, in the light
of the circumstances under which they were made, not misleading.

        Section 9.05. CONDITIONS OF INDEMNIFICATION.

               (a) All claims for indemnification under this Agreement shall be
        asserted and resolved as provided in this Section 9.05.

               (b) A party claiming indemnification under this Agreement (an
        "INDEMNIFIED PARTY") shall promptly (i) notify the party from whom
        indemnification is sought (the "INDEMNIFYING PARTY") of any third-party
        claim or claims asserted against the Indemnified Party ("Third Party
        Claim") that could give rise to a right of indemnification under this
        Agreement and (ii) transmit to the Indemnifying Party a written notice
        ("CLAIM NOTICE") describing in reasonable detail the nature of the Third
        Party Claim, a copy of all papers served with respect to the claim (if
        any), an estimate of the amount of damages attributable to the Third
        Party Claim to the extent feasible (which estimate shall not be
        conclusive of the final amount of the claim) and the basis for the
        Indemnified Party's request for indemnification under this Agreement.
        Except as set forth in Section 9.02, the failure to promptly deliver a
        Claim Notice shall not relieve the Indemnifying Party of its obligations
        to the Indemnified Party with respect to the related Third Party Claim
        except to the extent that the resulting delay is materially prejudicial
        to the defense of the claim. Within 15 days after receipt of any Claim
        Notice (the "ELECTION PERIOD"), the Indemnifying Party shall notify the
        Indemnified Party (i) whether the Indemnifying Party disputes its
        potential liability to the Indemnified Party under this Article IX with
        respect to the Third Party Claim and (ii) if the Indemnifying Party does
        not dispute its potential liability to the Indemnified Party with
        respect to the Third Party Claim, whether the Indemnifying Party
        desires, at the sole cost and expense of the Indemnifying Party, to
        defend the Indemnified Party against the Third Party Claim.


                                       58
<PAGE>
               (c) If the Indemnifying Party does not dispute its potential
        liability to the Indemnified Party and notifies the Indemnified Party
        within the Election Period that the Indemnifying Party elects to assume
        the defense of the Third Party Claim, then the Indemnifying Party shall
        have the right to defend, at its sole cost and expense, the Third Party
        Claim by all appropriate proceedings, which proceedings shall be
        prosecuted diligently by the Indemnifying Party to a final conclusion or
        settled at the discretion of the Indemnifying Party in accordance with
        this Section 9.05(c) and the Indemnified Party will furnish the
        Indemnifying Party with all information in its possession with respect
        to the Third Party Claim and otherwise cooperate with the Indemnifying
        Party in the defense of the Third Party Claim; PROVIDED, HOWEVER, that
        the Indemnifying Party shall not enter into any settlement with respect
        to any Third Party Claim that purports to limit the activities of, or
        otherwise restrict in any way, any Indemnified Party or any Affiliate of
        any Indemnified Party without the prior consent of that Indemnified
        Party (which consent may be withheld in the sole discretion of that
        Indemnified Party). The Indemnified Party is hereby authorized, at the
        sole cost and expense of the Indemnifying Party if found liable
        hereunder, to file, during the Election Period, any motion, answer or
        other pleadings that the Indemnified Party shall deem necessary or
        appropriate to protect its interests or those of the Indemnifying Party.
        The Indemnified Party may participate in, but not control, any defense
        or settlement of any Third Party Claim controlled by the Indemnifying
        Party pursuant to this Section 9.05(c) and will bear its own costs and
        expenses with respect to its participation; PROVIDED, HOWEVER, that if
        the named parties to any such action (including any impleaded parties)
        include both the Indemnifying Party and the Indemnified Party, and the
        Indemnified Party has been advised in writing by counsel that there may
        be one or more legal defenses available to it which are different from
        or additional to those available to the Indemnifying Party, then the
        Indemnified Party may employ separate counsel at the expense of the
        Indemnifying Party, and, on its written notification of that employment,
        the Indemnifying Party shall not have the right to assume or continue
        the defense of the action on behalf of the Indemnified Party.

               (d) If the Indemnifying Party (i) within the Election Period (A)
        disputes its potential liability to the Indemnified Party under this
        Article IX, (B) elects not to defend the Indemnified Party pursuant to
        Section 9.05(c) or (C) fails to notify the Indemnified Party that the
        Indemnifying Party elects to defend the Indemnified Party pursuant to
        Section 9.05(c) or (ii) elects to defend the Indemnified Party pursuant
        to Section 9.05(c) but fails diligently and promptly to prosecute or
        settle the Third Party Claim, then the Indemnified Party shall have the
        right to defend, at the sole cost and expense of the Indemnifying Party
        (if the Indemnified Party is entitled to indemnification hereunder), the
        Third Party Claim by all appropriate proceedings, which proceedings
        shall be promptly and vigorously prosecuted by the Indemnified Party to
        a final conclusion or settled. The Indemnified Party shall have full
        control of such defense and proceedings. Notwithstanding the foregoing,
        if the Indemnifying Party has delivered a written notice to the
        Indemnified Party to the effect that the Indemnifying Party disputes its
        potential liability to the Indemnified Party under this Article IX and
        if such dispute is resolved in favor of the Indemnifying Party, the
        Indemnifying Party


                                       59
<PAGE>
        shall not be required to bear the costs and expenses of the Indemnified
        Party's defense pursuant to this Section 9.05 or of the Indemnifying
        Party's participation therein at the Indemnified Party's request, and
        the Indemnified Party shall reimburse the Indemnifying Party in full for
        all reasonable and appropriate costs and expenses of such litigation.
        The Indemnifying Party may participate in, but not control, any defense
        or settlement controlled by the Indemnified Party pursuant to this
        Section 9.05(d), and the Indemnifying Party shall bear its own costs and
        expenses with respect to such participation.

               (e) If any Indemnified Party should have a claim against any
        Indemnifying Party hereunder that does not involve a Third Party Claim,
        the Indemnified Party shall transmit to the Indemnifying Party a written
        notice (the "INDEMNITY NOTICE") describing in reasonable detail the
        nature of the claim, an estimate of the amount of Damages attributable
        to that claim to the extent feasible (which estimate shall not be
        conclusive of the final amount of the claim) and the basis of the
        Indemnified Party's request for indemnification under this Agreement. If
        the Indemnifying Party does not notify the Indemnified Party within 30
        days from its receipt of the Indemnity Notice that the Indemnifying
        Party disputes the claim, the claim specified by the Indemnified Party
        in the Indemnity Notice shall be deemed a liability of the Indemnifying
        Party hereunder. If the Indemnifying Party has timely disputed the
        claim, as provided above, the dispute shall be resolved by proceedings
        in an appropriate court of competent jurisdiction if the parties do not
        reach a settlement of such dispute within 60 days after the date of
        delivery of the Indemnity Notice.

               (f) Payments of all amounts owing by an Indemnifying Party
        pursuant to this Article IX relating to a Third Party Claim shall be
        made within 30 days after the latest of (i) the settlement of that Third
        Party Claim, (ii) the expiration of the period for appeal of a final
        adjudication of that Third Party Claim or (iii) the expiration of the
        period for appeal of a final adjudication of the Indemnifying Party's
        liability to the Indemnified Party under this Agreement. Payments of all
        amounts owing by an Indemnifying Party pursuant to Section 9.05(e) shall
        be made within 30 days after the later of (i) the expiration of the
        60-day Indemnity Notice period or (ii) the expiration of the period for
        appeal of a final adjudication of the Indemnifying Party's liability to
        the Indemnified Party under this Agreement. If and after the aggregate
        amount of all Damage Claims paid by a Stockholder under this Article IX
        equals or exceeds the amount of cash included in the Merger
        Consideration received by that Stockholder, then that Stockholder, in
        payment and satisfaction of any remaining unsatisfied or subsequent
        Damage Claims in respect of which that Stockholder may be required to
        indemnify any OEI Indemnified Party, may transfer and surrender to the
        Company such number of shares of OEI Common Stock included in the Merger
        Consideration received by such Stockholder as shall equal (i) the amount
        of all such remaining unsatisfied or subsequent Damage Claims divided by
        (ii) $12 or, if at the time such Stockholder pays such remaining Damage
        Claim such Stockholder is prohibited from selling shares of the OEI
        Common Stock pursuant to Section 11.02, the greater of $12 or the
        Current Market Price.

        Section 9.06. REMEDIES EXCLUSIVE. Except as otherwise expressly provided
in this Agreement, the remedies provided in this Article IX are the exclusive
remedies available to one party against the other, either at law or in equity,
in respect of any matter indemnified against in this Article IX.

        Section 9.07. LIMITATIONS ON INDEMNIFICATION.

               (a) Notwithstanding the provisions of Section 9.03(a), neither
        the Company nor any of the Stockholders shall be required to indemnify
        or hold harmless any of the OEI Indemnified Parties on account of any
        OEI Indemnified Loss under Section 9.03(a) unless the liability of the
        Company and the Stockholders in respect of that OEI Indemnified Loss,
        when aggregated with the liability of the Company and the Stockholders
        in respect of all OEI Indemnified Losses under Section 9.03 (a),
        exceeds, and only to the extent the aggregate amount of all those OEI
        Indemnified Losses does exceed, the Threshold Amount. In no event shall
        (i) the aggregate joint and several liability of the Company and the
        Stockholders under this Agreement, including Section 9.03(a), exceed the
        Ceiling Amount or (ii) the aggregate liability of each Stockholder under
        this Agreement, including Sections 9.03(a) and 9.03(b), exceed the
        product of the Pro Rata Share of that Stockholder multiplied by the
        Ceiling Amount.

               (b) Notwithstanding the provisions of Section 9.04, OEI shall not
        be required to indemnify or hold harmless any of the Stockholder
        Indemnified Parties on account of any Stockholder Indemnified Loss
        unless the liability of OEI in respect of that Stockholder Indemnified
        Loss, when aggregated with the liability of OEI in respect of all
        Stockholder Indemnified Losses, exceeds, and only to the extent the
        aggregate amount of all those Stockholder Indemnified Losses does
        exceed, the Threshold Amount. In no event shall OEI be liable under this
        Agreement, including Section 9.04, for any amount in excess of the
        Ceiling Amount.

                                   ARTICLE XI

                               GENERAL PROVISIONS

        Section 11.01.TREATMENT OF CONFIDENTIAL INFORMATION.

               (a) Each of the Company and the Stockholders, severally and not
        jointly with any other Person, acknowledges that it has or may have had
        in the past, currently has and in the future may have access to
        Confidential Information of the Company and the Company Subsidiaries,
        the Other Founding Companies and their Subsidiaries and OEI and its
        Subsidiaries. Each of the Company and the Stockholders, severally and
        not jointly with any other Person, agrees that it will keep confidential
        all such Confidential Information furnished to it and, except with the
        specific prior written consent of OEI will not disclose such
        Confidential Information to any Person except (a) Representatives of
        OEI, (b) its own Representatives, provided that these Representatives
        (other than counsel) agree to the confidentiality provisions of this
        Section 11.01; and provided, further, that Confidential Information
        shall not include (i) such information which becomes known to the public
        generally through no fault of any Stockholder, (ii) information required
        to be disclosed by law or the order of any governmental authority under
        color of law, provided, that prior to disclosing any information
        pursuant to this clause (ii), each Stockholder shall, if possible, give
        prior written notice thereof to OEI and provide OEI with the opportunity
        to contest such disclosure, or (iii) the disclosing party reasonably
        believes that such disclosure is required in connection with the defense
        of a lawsuit against the disclosing party. In the event of a breach or
        threatened breach by any Stockholder of the provisions of this Section
        11.01 with respect to any Confidential Information, OEI shall be
        entitled to an injunction restraining such Stockholder from disclosing,
        in whole or in part, that Confidential Information. Nothing herein shall
        be construed as prohibiting OEI from pursuing any other available remedy
        for such breach or threatened breach, including the recovery of damages.

               (b) Because of the difficulty of measuring economic losses as a
        result of the breach of the foregoing covenants in Section 11.01(a), and
        because of the immediate and irreparable damage that would be caused to
        OEI for which it would have no other adequate remedy, each of the
        Company and the Stockholders agrees that OEI may enforce the provisions
        of Section 11.01(a) by injunctions and restraining orders against each
        of them who breaches any of those provisions.

               (c) The obligations of OEI set forth in Section 6.02(d) are
        incorporated in this Section 11.01 by this reference.

               (d) The obligations of the parties under this Section 11.01 shall
        survive the termination of this Agreement.

        Time, but which are not payable until a date subsequent to surrender,
        which are payable with respect to such number of whole shares of OEI
        Common Stock, subject in all cases to any applicable escheat laws. No

        Security outstanding on the date hereof, the name of the holder of such
        Derivative Security, the number of shares of Company Common Stock
        covered by such Derivative Security and the exercise price and
        expiration date of such Derivative Security. Each ISO, NSO and Warrant
        outstanding at the Effective Time shall be exchanged for a Substitute
        ISO, Substitute NSO and Substitute Warrant, respectively, which will
        entitle the holder of such Derivative Security to purchase a number of
        shares (rounded to the nearest whole share) of OEI Common Stock equal to
        the number of shares of Company Common Stock subject to the Derivative
        Security for which such Substitute Derivative Security is being
        exchanged multiplied by the Derivative Security Conversion Ratio. The
        exercise price per share of OEI Common Stock for each Substitute
        Derivative Security shall be an amount (rounded to the nearest whole
        cent) equal to the exercise price applicable to the Outstanding
        Derivative Security for which such Substitute Derivative Security is
        being exchanged divided by the Derivative Security Conversion Ratio.
        Each Substitute Derivative Security will have the same expiration date,
        and shall contain substantially the same terms (other than the exercise
        price), as the Derivative Security for which such Substitute Derivative
        Security is being exchanged. Each Substitute ISO and each Substitute NSO
        will be subject in all respects to


                                        8
<PAGE>
        the terms of the Incentive Plan. Each of the Substitute Warrants will be
        issued pursuant to, and will be subject in all respects to the terms of,
        the Substitute Warrant Agreement.

               (b) CONSENT TO EXCHANGE. By execution of this Agreement, each
        Stockholder and each Family Partnership Affiliate who is the holder of
        Outstanding Derivative Securities agrees that each such Outstanding
        Derivative Security which is outstanding at the Effective Time will be

        Stockholder has agreed in writing that each such Outstanding Derivative
        Security will be exchanged for a Substitute Derivative Security in

        the Business Corporation Act and providing that the Merger will become

(other than the Company) will comply with each covenant for which provision is

is incorporated herein by this reference) to be performed or observed by that
Party.

                                   ARTICLE IX

reference. For purposes of Sections 9.03(a) and 9.03(d), the term "Stockholders"

                           LIMITATIONS ON COMPETITION

        Section 10.01. PROHIBITED ACTIVITIES. Each Stockholder identified on
Schedule 10.01 (each a "Restricted Stockholder") and, in the case of paragraphs
(b) and (d) below of this Section 10.01, each Stockholder, severally agrees that
he will not during the period beginning on the date hereof and ending on the
third anniversary of the date hereof, directly or indirectly, for any reason,
for his own account or on behalf of or together with any other Person:

               (a) engage as an officer, director or in any other managerial
        capacity or as an owner, co-owner or other investor of or in, whether as
        an employee, independent contractor, consultant or advisor, in any
        business engaged in the Practice of Engineering in competition with the
        Company, any Company Subsidiary or OEI or any Subsidiary of OEI (OEI and
        its Subsidiaries collectively being called "OEI" for purposes of this
        Article X) within any territory surrounding any office or facility (each
        a "facility") in which any of the Company or the Company Subsidiaries
        was engaged in business on the date hereof or immediately prior to the
        Effective Time (for purposes of this Article X, the territory
        surrounding a facility shall be: (i) the city, town or village in which
        the facility is located, (ii) the county or parish in which the facility
        is located, (iii) the counties or parishes contiguous to the county or
        parish in which the facility is located, and (iv) the area located
        within 100 miles of the facility, all of such locations being herein
        collectively called the "TERRITORY");

               (b) call on any natural Person who is at that time employed by
        the Company, any Company Subsidiary or OEI with the purpose or intent of
        attracting that person from the employ of the Company, any Company
        Subsidiary or OEI, provided that a Stockholder may call on and hire any
        of his Immediate Family Members;

               (c) call on any Person that at that time is, or at any time
        within one year prior to that time was, a customer of the Company, any
        Company Subsidiary or OEI within the Territory, (i) for the purpose of
        soliciting or selling any product or service in competition with the
        Company, any Company Subsidiary or OEI within the Territory and (ii)
        with the knowledge of the customer relationship; or

               (d) call on any OEI Acquisition Candidate, with the knowledge of
        that Person's status as an OEI Acquisition Candidate, for the purpose of
        acquiring that Person or arranging the acquisition of that Person by any
        Person other than OEI.

Notwithstanding the foregoing, any Restricted Stockholder may own and hold as a
passive investment up to 1% of a class of the outstanding Capital Stock of a
competing Entity if that class of Capital Stock is publicly traded.

<PAGE>
        Section 10.02. DAMAGES. Because of the difficulty of measuring economic
losses to OEI as a result of any breach by a Restricted Stockholder or any other
Stockholder of his covenants in Section 10.01, and because of the immediate and
irreparable damage that could be caused to OEI for which it would have no other
adequate remedy, each Restricted Stockholder (and, in the case of paragraphs (b)
and (d) of Section 10.01, each Stockholder) agrees that OEI may enforce the
provisions of Section 10.01 by injunctions and restraining orders against the
Restricted Stockholder or Stockholder, as the case may be, if he breaches any of
those provisions.

        Section 10.03. REASONABLE RESTRAINT. The Parties each agree that
Sections 10.01 and 10.02 impose a reasonable restraint on the Restricted
Stockholder or Stockholders, as the case may be, in light of the activities and
business of OEI on the date hereof, the current business plans of OEI and the
investment by each Stockholder in OEI as a result of the Merger.

        Section 10.04. SEVERABILITY; REFORMATION. The covenants in this Article
X are severable and separate. The unenforceability of any specific covenant in
this Article X is not intended by any Party to, and shall not, affect the
provisions of any other covenant in this Article X. If any court of competent
jurisdiction determines that the scope, time or territorial restrictions set
forth in Section 10.01 are unreasonable as applied to any Restricted Stockholder
or Stockholder, as the case may be, the Parties, including the Restricted
Stockholder or Stockholder in question, acknowledge their mutual intention and
agreement that those restrictions be enforced to the fullest extent the court
deems reasonable, and thereby shall be reformed to that extent as applied to
that Restricted Stockholder or Stockholder, as the case may be, and any other
Restricted Stockholder or Stockholder, as the case may be, similarly situated.

        Section 10.05. INDEPENDENT COVENANT. All the covenants in this Article X
are intended by each Party to, and shall, be construed as an agreement
independent of any other provision in this Agreement, and the existence of any
claim or cause of action of any Restricted Stockholder or Stockholder against
OEI, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by OEI of any covenant in this Article X. It is
specifically agreed that the period specified in Section 10.01 shall be computed
in the case of each Restricted Stockholder and Stockholder by excluding from
that computation any time during which the Restricted Stockholder or Stockholder
is in violation of any provision of Section 10.01. The covenants contained in
this Article X shall not be affected by any breach of any other provision of
this Agreement by any Party.

        Section 10.06. MATERIALITY. The Company and each Stockholder, severally
and not jointly with any other Person, hereby agree that this Article X is a
material and substantial part of the transactions contemplated by this
Agreement.

        Section 11.02. RESTRICTIONS ON TRANSFERS OF OEI COMMON STOCK.

               (a) During the two-year period ending on the second anniversary
        of the IPO Closing Date (the "RESTRICTED PERIOD"), no Stockholder
        voluntarily will: (i) sell, assign, exchange, transfer, encumber,
        pledge, distribute, appoint or otherwise dispose of (A) any shares of
        OEI Common Stock received by any Stockholder in the Merger (including
        but not limited to shares issued or to be issued pursuant to any of the
        Substitute Derivative Securities received by such Stockholder pursuant
        to Section 2.07(a)) or (B) any interest in (including any option to buy
        or sell) any such shares of OEI Common Stock, in whole or in part, and
        OEI will have no obligation to, and shall not, treat any such attempted
        transfer as effective for any purpose; or (ii) engage in any
        transaction, whether or not with respect to any shares of OEI Common
        Stock or any interest therein, the intent or effect of which is to
        reduce the risk of owning the shares of OEI Common Stock acquired
        pursuant to Section 2.04 (including, for example engaging in put, call,
        short-sale, straddle or similar market transactions); PROVIDED, HOWEVER,
        that this Section 11.02 shall not restrict any transfer of OEI Common
        Stock acquired by a Stockholder pursuant to Section 2.04 to any of that
        Stockholder's Related Persons who agree in writing to be bound by the
        provisions of Section 11.01 and this Section 11.02. The certificates
        evidencing the OEI Common Stock delivered to each Stockholder pursuant
        to Section 2.05 will bear a legend substantially in the form set forth
        below and containing such other information as OEI may deem necessary or
        appropriate:

               EXCEPT PURSUANT TO THE TERMS OF THE AGREEMENT AND PLAN OF
               REORGANIZATION AMONG THE ISSUER, THE HOLDER OF THIS CERTIFICATE
               AND THE OTHER PARTIES THERETO, THE SHARES REPRESENTED BY THIS

        delivered to him pursuant to Section 2.04 (A) have not been and, except
        pursuant to the Registration Rights Agreement, if applicable, will not
        be registered under the Securities Act and therefore may not be resold
        by him without compliance with the Securities Act and (B) will, as a
        result of their restrictions on transferability which are imposed by
        this Agreement during the Restricted Period, have a value materially
        less at the Effective Time than the value of then freely tradeable
        shares of OEI Common Stock, and (ii) covenants that none of the shares
        of OEI Common Stock issued to him pursuant to Section 2.04 will be
        offered, sold, assigned, pledged, hypothecated, transferred or otherwise
        disposed of except after full compliance with all the applicable
        provisions of the Securities Act and the rules and regulations of the
        SEC and applicable state securities laws and regulations. All

               OTHERWISE TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THAT ACT
               AND OTHER APPLICABLE SECURITIES LAWS.

        In addition, certificates evidencing shares of OEI Common Stock issued
        to each Stockholder pursuant to Section 2.04 will bear any legend
        required by (i) the securities or blue sky laws of the state in which
        that Stockholder resides or (ii) the Underwriter in connection with any
        agreement of that Stockholder with the Underwriter to the effect set
        forth in Section 11.02(a).

        Section 11.03. BROKERS AND AGENTS. The Stockholders jointly and
severally represent and warrant to OEI that the Company has not directly or

of OEI, and the heirs and legal representatives of the Stockholders (and, in the
case of any trust, the successor trustees of the trust). Neither this Agreement

interpreted, to confer on any Person not a party hereto or thereto any rights or

subject matter of this Agreement. This Agreement may be amended, modified or
supplemented, and any right hereunder may be waived, if, but only if, the
amendment, modification, supplement or waiver is in writing and signed by the
Majority Stockholders, the Company and OEI. The waiver of any of the terms and
conditions of this Agreement shall not be construed or interpreted as, or deemed
to be, a waiver of any of its other term or conditions.

        Section 11.06. COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which will be an original, but all of which together will
constitute one and the same instrument.

the aggregate of Counsel for the Company and the Stockholders incurred in
connection with the subject matter of this Agreement and the Registration

Surviving Corporation, will pay all Taxes due upon receipt of the consideration
payable to the Stockholder pursuant to Article II.

oral or written, exists at the date hereof that the Registration Statement will

Representatives nor any prospective underwriters in the IPO will have any
liability to the Company, the Stockholders or any of their respective Affiliates

cause the Registration Statement to become effective prior to October 31, 1998)
or (ii) the IPO to occur at a particular price or within a particular range of
prices or to occur at all; and (c) the decision of Stockholders to enter into

Affiliate of such Family Partnership as a direct and primary obligation of such
Family Partnership Affiliate.

        date hereof and prior to the Effective Time there shall begin to run,
        any period of time (herein called a


                                       21
<PAGE>
        "LIMITATION PERIOD") within which any party bound by or entitled to the
        benefits of, or whose shares of the Common Stock are subject to, the
        Shareholders' Agreement must, under the terms of the Shareholders'
        Agreement, give any notice, offer such shares for sale, accept any offer
        to purchase any such shares, purchase shares, make any election or take
        any other action in order to preserve or maintain any right or benefit
        of such party, then such Limitation Period shall cease to run and shall
        be tolled as of the date of this Agreement, or, in the case of any
        Limitation Period beginning after the date hereof, shall not begin to
        run, unless and until such Limitation Period shall be resumed and
        reinstated as provided in the following Section 11.18(e);

               (d) so long as any Limitation Period is tolled pursuant to
        Section 11.18(c), no party to the Shareholders' Agreement may exercise
        any right or option such party would otherwise have but for the
        provisions of this Section 11.18; and

               (e) if this Agreement is terminated pursuant to Article XII, then
        as of the close of business on the date this Agreement is so terminated,
        the provisions of this Section 11.18 shall terminate and any Limitation
        Period shall resume and be reinstated or shall commence, as the case may
        be, ten days following such termination, and promptly thereafter, the
        Company shall notify each of the parties to the Shareholders' Agreement
        that the provisions of this Section 11.18 have terminated.

By their execution and delivery of this Agreement, pursuant to Section 20 of the
Shareholders' Agreement, the Company and the Stockholders (who hold more than
67% of the shares of Capital Stock subject to the Shareholders' Agreement)
hereby amend the Shareholders' Agreement as set forth in this Section 11.18.

                                   TERMINATION

        Section 12.01. TERMINATION OF THIS AGREEMENT.

               (a)     This Agreement may be terminated at any time prior to the
 Closing solely:

                       (i)  by the mutual written consent of OEI and the
               Company;

                       (ii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if the transactions
               contemplated by this Agreement to take place at the Closing shall
               not have been consummated by October 31, 1998, unless the failure
               of such transactions to be consummated results from the willful
               failure of the Party (or in the case of the Stockholders and the
               Company, any of them) seeking to terminate this Agreement to
               perform or adhere to any agreement required hereby to be
               performed or adhered to by that Party prior to or at the Closing
               or thereafter on the IPO Closing Date;


                                       22
<PAGE>
                       (iii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if a material breach or
               default shall be made by the other Party (or in the case of the
               Stockholders and the Company, any of them) in the observance or
               in the due and timely performance of any of the covenants,
               agreements or conditions contained herein; or

                       (iv) by OEI if it is entitled to do so as provided in
               Section 6.07;

               (b) This Agreement may be terminated after the Closing solely:

                       (i) by OEI or the Company if the Underwriting Agreement
               is terminated pursuant to its terms after the Closing and prior
               to the consummation of the IPO; or

                       (ii) automatically and without action on the part of any
               party hereto if the IPO is not consummated within 15 Business
               Days after the date of the Closing.

               (c) If this Agreement is terminated pursuant to this Section
        12.01, the Merger will be deemed for all purposes to have been abandoned
        and of no force or effect. If this Agreement is terminated pursuant to
        this Section 12.01 after the Certificate of Merger has been filed with
        the Secretary of State of the State of Texas, but before the IPO has
        been consummated, OEI will take all actions that Counsel for the Company
        and the Stockholders advises OEI are required by the applicable laws of
        the State of Texas to rescind the Merger.

        Section 12.02. LIABILITIES IN EVENT OF TERMINATION. If this Agreement is
terminated pursuant to Section 12.01, there shall be no liability or obligation
on the part of any Party except (a) as provided in Section 11.07, (b) to the
extent that such liability is based on the breach of that Party of any of its or
his representations, warranties or covenants set forth in of this Agreement.

        IN WITNESS WHEREOF, the Parties have executed this Agreement as of the
date first above written.

        purposes, be deemed to evidence ownership of the number of whole shares
        of OEI Common Stock included in the Merger Consideration payable in
        respect of that certificate pursuant to Section 2.04. All shares of OEI
        Common Stock issuable in the Merger will be deemed for all purposes to
        have been issued by OEI at the Effective Time. All cash included in the
        Merger Consideration shall be paid by OEI's company checks, certified or
        official bank checks, or wire transfers, at OEI's option. In the case of

        terminated pursuant to Article XII prior to the Effective Time, OEI or
        its agent will return all such certificates and other documents to the
        Stockholders. Each Stockholder shall cure any deficiencies in the
        endorsement of the certificates or other documents of conveyance
        respecting, or in the stock powers accompanying, the certificates
        representing Company Common Stock delivered by him.

               (c) No dividends (or interest) or other distributions declared or
        earned after the Effective Time with respect to OEI Common Stock and
        payable to the holders of record thereof after the Effective Time will
        be paid to the holder of any unsurrendered certificates representing
        shares of Company Common Stock for which shares of OEI Common Stock have
        been issued in the Merger until the unsurrendered certificates are
        surrendered as provided herein, but (i) on such surrender, OEI will
        cause to be paid, to the Person in whose name the certificates
        representing such shares of OEI Common Stock shall then be issued, the
        amount of dividends or other distributions previously paid with respect
        to such whole shares of OEI Common Stock with a record date, or which
        have accrued, subsequent to the Effective Time, but prior to surrender,

        fractional shares pursuant to Section 2.06 and (ii) at the appropriate
        payment date or as soon as practicable thereafter, OEI will cause to be
        paid to that Person the amount of dividends or other distributions with
        a record date, or which have been accrued, subsequent to the Effective
        Time, but which are not payable until a date subsequent to surrender,
        which are payable with respect to such number of whole shares of OEI
        Common Stock, subject in all cases to any applicable escheat laws. No
        interest will be payable with respect to the payment of such dividends
        or other distributions (or cash for and in lieu of fractional shares) on
        surrender of outstanding certificates.

        Section 2.06. FRACTIONAL SHARES. Notwithstanding any other provision of
this Article II, no fractional shares of OEI Common Stock will be issued, and
any Stockholder otherwise entitled to receive a fractional share of OEI Common
Stock but for this Section 2.06 will instead be entitled to receive a cash
payment for and in lieu thereof in the amount (rounded to the nearest whole
cent) equal to that Person's fractional interest in a share of OEI Common Stock
multiplied by $12.

               (e) INCORPORATION OF ARTICLE VII OF UNIFORM PROVISIONS. The text
        of Article VII of the Uniform Provisions hereby is incorporated herein
        by this reference.

                                         ARTICLE VIII

                            COVENANTS FOLLOWING THE EFFECTIVE TIME

        Section 8.01. OF EACH PARTY OTHER THAN THE COMPANY. From and after the
Effective Time, subject to the waiver provisions of Section 11.05, each Party
(other than the Company) will comply with each covenant for which provision is
made in Article VIII of the Uniform Provisions (the text of which Article hereby
is incorporated herein by this reference) to be performed or observed by that
Party.

                                          ARTICLE IX

                                        INDEMNIFICATION

        Section 9.01. INDEMNIFICATION RIGHTS AND OBLIGATIONS. The text of
Article IX of the Uniform Provisions hereby is incorporated herein by this
reference.

                                           ARTICLE X

                                  LIMITATIONS ON COMPETITION

        Section 10.01. PROHIBITED ACTIVITIES. Each Stockholder identified on
Schedule 10.01 (each a "Restricted Stockholder") and, in the case of paragraphs
(b) and (d) below of this Section 10.01, each Stockholder, severally agrees that
he will not during the period beginning on the date hereof and ending on the
third anniversary of the date hereof, directly or indirectly, for any reason,
for his own account or on behalf of or together with any other Person:

               (a) engage as an officer, director or in any other managerial
        capacity or as an owner, co-owner or other investor of or in, whether as
        an employee, independent contractor, consultant or advisor, in any
        business engaged in the Practice of Engineering in competition with the
        Company, any Company Subsidiary or OEI or any Subsidiary of OEI (OEI and
        its Subsidiaries collectively being called "OEI" for purposes of this
        Article X) within any territory surrounding any office or facility (each
        a "facility") in which any of the Company or the Company Subsidiaries
        was engaged in business on the date hereof or immediately prior to the
        Effective Time (for purposes of this Article X, the territory
        surrounding a facility shall be: (i) the city, town or village in which
        the facility is located, (ii) the county or parish in which the facility
        is located, (iii) the counties or parishes contiguous to the county or
        parish in which the facility is located, and (iv) the area located
        within 100 miles of the facility, all of such locations being herein
        collectively called the "TERRITORY");


                                              11
<PAGE>
               (b) call on any natural Person who is at that time employed by
        the Company, any Company Subsidiary or OEI with the purpose or intent of
        attracting that person from the employ of the Company, any Company
        Subsidiary or OEI, provided that a Stockholder may call on and hire any
        of his Immediate Family Members;

               (c) call on any Person that at that time is, or at any time
        within one year prior to that time was, a customer of the Company, any
        Company Subsidiary or OEI within the Territory, (i) for the purpose of
        soliciting or selling any product or service in competition with the
        Company, any Company Subsidiary or OEI within the Territory and (ii)
        with the knowledge of the customer relationship; or

               (d) call on any OEI Acquisition Candidate, with the knowledge of
        that Person's status as an OEI Acquisition Candidate, for the purpose of
        acquiring that Person or arranging the acquisition of that Person by any
        Person other than OEI.

Notwithstanding the foregoing, any Restricted Stockholder may own and hold as a
passive investment up to 1% of a class of the outstanding Capital Stock of a
competing Entity if that class of Capital Stock is publicly traded.

        Section 10.02. DAMAGES. Because of the difficulty of measuring economic
losses to OEI as a result of any breach by a Restricted Stockholder or any other
Stockholder of his covenants in Section 10.01, and because of the immediate and
irreparable damage that could be caused to OEI for which it would have no other
adequate remedy, each Restricted Stockholder (and, in the case of paragraphs (b)
and (d) of Section 10.01, each Stockholder) agrees that OEI may enforce the
provisions of Section 10.01 by injunctions and restraining orders against the
Restricted Stockholder or Stockholder, as the case may be, if he breaches any of
those provisions.

        Section 10.03. REASONABLE RESTRAINT. The Parties each agree that
Sections 10.01 and 10.02 impose a reasonable restraint on the Restricted
Stockholder or Stockholders, as the case may be, in light of the activities and
business of OEI on the date hereof, the current business plans of OEI and the
investment by each Stockholder in OEI as a result of the Merger.

        Section 10.04. SEVERABILITY; REFORMATION. The covenants in this Article
X are severable and separate. The unenforceability of any specific covenant in
this Article X is not intended by any Party to, and shall not, affect the
provisions of any other covenant in this Article X. If any court of competent
jurisdiction determines that the scope, time or territorial restrictions set
forth in Section 10.01 are unreasonable as applied to any Restricted Stockholder
or Stockholder, as the case may be, the Parties, including the Restricted
Stockholder or Stockholder in question, acknowledge their mutual intention and
agreement that those restrictions be enforced to the fullest extent the court
deems reasonable, and thereby shall be reformed to that extent as applied to
that Restricted Stockholder or Stockholder, as the case may be, and any other
Restricted Stockholder or Stockholder, as the case may be, similarly situated.


                                              12
<PAGE>
        Section 10.05. INDEPENDENT COVENANT. All the covenants in this Article X
are intended by each Party to, and shall, be construed as an agreement
independent of any other provision in this Agreement, and the existence of any
claim or cause of action of any Restricted Stockholder or Stockholder against
OEI, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by OEI of any covenant in this Article X. It is
specifically agreed that the period specified in Section 10.01 shall be computed
in the case of each Restricted Stockholder and Stockholder by excluding from
that computation any time during which the Restricted Stockholder or Stockholder
is in violation of any provision of Section 10.01. The covenants contained in
this Article X shall not be affected by any breach of any other provision of
this Agreement by any Party.

        Section 10.06. MATERIALITY. The Company and each Stockholder, severally
and not jointly with any other Person, hereby agree that this Article X is a
material and substantial part of the transactions contemplated by this
Agreement.

                                          ARTICLE XI

                                      GENERAL PROVISIONS

        Section 11.01. TREATMENT OF CONFIDENTIAL INFORMATION. Each Party will
comply with each covenant for which provision is made in Section 11.01 of the
Uniform Provisions (the text of which Section hereby is incorporated herein by
this reference) to be performed or observed by that Party.

        Section 11.02. RESTRICTIONS ON TRANSFERS OF OEI COMMON STOCK.

               (a) During the two-year period ending on the second anniversary
        of the IPO Closing Date (the "RESTRICTED PERIOD"), no Stockholder
        voluntarily will: (i) sell, assign, exchange, transfer, encumber,
        pledge, distribute, appoint or otherwise dispose of (A) any shares of
        OEI Common Stock received by any Stockholder in the Merger or (B) any
        interest in (including any option to buy or sell) any such shares of OEI
        Common Stock, in whole or in part, and OEI will have no obligation to,
        and shall not, treat any such attempted transfer as effective for any
        purpose; or (ii) engage in any transaction, whether or not with respect
        to any shares of OEI Common Stock or any interest therein, the intent or
        effect of which is to reduce the risk of owning the shares of OEI Common
        Stock acquired pursuant to Section 2.04 (including, for example engaging
        in put, call, short-sale, straddle or similar market transactions);
        PROVIDED, HOWEVER, that this Section 11.02 shall not restrict any
        transfer of OEI Common Stock acquired by a Stockholder pursuant to
        Section 2.04 to any of that Stockholder's Related Persons who agree in
        writing to be bound by the provisions of Section 11.01 and this Section
        11.02. The certificates evidencing the OEI Common Stock delivered to
        each Stockholder pursuant to Section 2.05 will bear a legend
        substantially in the form set forth below and containing such other
        information as OEI may deem necessary or appropriate:


                                              13
<PAGE>
               EXCEPT PURSUANT TO THE TERMS OF THE AGREEMENT AND PLAN OF
               REORGANIZATION AMONG THE ISSUER, THE HOLDER OF THIS CERTIFICATE
               AND THE OTHER PARTIES THERETO, THE SHARES REPRESENTED BY THIS
               CERTIFICATE MAY NOT BE VOLUNTARILY SOLD, ASSIGNED, EXCHANGED,
               TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR
               OTHERWISE DISPOSED OF, AND THE ISSUER SHALL NOT BE REQUIRED TO
               GIVE EFFECT TO ANY ATTEMPTED VOLUNTARY SALE, ASSIGNMENT,
               EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION,
               APPOINTMENT OR OTHER DISPOSITION OF ANY OF THOSE SHARES, DURING
               THE TWO-YEAR PERIOD ENDING ON [DATE THAT IS THE SECOND
               ANNIVERSARY OF THE IPO CLOSING DATE] (THE "RESTRICTED PERIOD").
               ON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE
               ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP
               ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE EXPIRATION OF THE
               RESTRICTED PERIOD.

               (b) Each Stockholder, severally and not jointly with any other
        Person, (i) acknowledges that the shares of OEI Common Stock to be
        delivered to him pursuant to Section 2.04 (A), if any, have not been
        and, except pursuant to the Registration Rights Agreement, if
        applicable, will not be registered under the Securities Act and
        therefore may not be resold by him without compliance with the
        Securities Act and (B) will, as a result of their restrictions on
        transferability which are imposed by this Agreement during the
        Restricted Period, have a value materially less at the Effective Time
        than the value of then freely tradeable shares of OEI Common Stock, and
        (ii) covenants that none of the shares of OEI Common Stock issued to him
        pursuant to Section 2.04 will be offered, sold, assigned, pledged,
        hypothecated, transferred or otherwise disposed of except after full
        compliance with all the applicable provisions of the Securities Act and
        the rules and regulations of the SEC and applicable state securities
        laws and regulations. All certificates evidencing shares of OEI Common
        Stock issued pursuant to Section 2.04 will bear the following legend in
        addition to the legend prescribed by Section 11.02(a):

               THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
               SECURITIES ACT OF 1933, AS AMENDED, AND MAY ONLY BE SOLD OR
               OTHERWISE TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THAT ACT
               AND OTHER APPLICABLE SECURITIES LAWS.

        In addition, certificates evidencing any shares of OEI Common Stock
        issued to each Stockholder pursuant to Section 2.04 will bear any legend
        required by (i) the securities or blue sky laws of the state in which
        that Stockholder resides or (ii) the Underwriter in connection with any
        agreement of that Stockholder with the Underwriter to the effect set
        forth in Section 11.02(a).

        Section 11.03. BROKERS AND AGENTS. The Stockholders jointly and
severally represent and warrant to OEI that the Company has not directly or
indirectly employed or become obligated to pay any broker or similar agent in
connection with the transactions contemplated hereby and agree, without regard
to the Threshold Amount limitations set forth in Article IX, to indemnify OEI
against

                                              14
<PAGE>
all Damage Claims arising out of claims for any and all fees and commissions of
brokers or similar agents employed or promised payment by the Company.

        Section 11.04. ASSIGNMENT; NO THIRD PARTY BENEFICIARIES. This Agreement
and the rights of its Parties may not be assigned (except by operation of law)
and shall be binding on and inure to the benefit of the Parties, the successors
of OEI, and the heirs and legal representatives of the Stockholders (and, in the
case of any trust, the successor trustees of the trust). Neither this Agreement
nor any other Transaction Document is intended, or shall be construed, deemed or
interpreted, to confer on any Person not a party hereto or thereto any rights or
remedies hereunder or thereunder, except as provided in Section 6.05(b) or
11.14, in Article IX, or as otherwise provided expressly herein or therein.

        Section 11.05. ENTIRE AGREEMENT; AMENDMENT; WAIVERS. This Agreement and
the documents delivered pursuant to it constitute the entire agreement and
understanding among the Parties and supersede all prior agreements and
understandings, both written and oral, relating to the subject matter of this
Agreement. This Agreement may be amended, modified or supplemented, and any
right hereunder may be waived, if, but only if, the amendment, modification,
supplement or waiver is in writing and signed by the Majority Stockholders, the
Company and OEI. The waiver of any of the terms and conditions of this Agreement
shall not be construed or interpreted as, or deemed to be, a waiver of any of
its other term or conditions.

        Section 11.06. COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which will be an original, but all of which together will
constitute one and the same instrument.

        Section 11.07. EXPENSES. Whether or not the transactions contemplated
hereby are consummated, (a) OEI will pay the fees, expenses and disbursements of
OEI and Newco and their Representatives which are incurred in connection with
the subject matter of this Agreement and any amendments to this Agreement
including all costs and expenses incurred in the performance of and compliance
with all conditions to be performed by OEI and Newco under this Agreement,
including the costs of preparing the Registration Statement, (b) the Company may
pay any fees, expenses and disbursements of Counsel for the Company and the
Stockholders incurred in connection with the subject matter of this Agreement
and the Registration Statement on or before the IPO Closing Date, up to a
maximum of $40,000 in the aggregate for all such fees, expenses and
disbursements incurred after January 16, 1998, and (c) the Stockholders will pay
from personal funds, and not from funds of the Company or any Company
Subsidiary, (i) all sales, use, transfer and other similar taxes and fees
(collectively, "TRANSFER TAXES") incurred in connection with the transactions
contemplated hereby, and (ii) the fees, expenses and disbursements in excess of
$40,000 in the aggregate of Counsel for the Company and the Stockholders
incurred in connection with the subject matter of this Agreement and the
Registration Statement after January 13, 1998, and on or before the IPO Closing
Date. The Stockholders will file all necessary documentation and Returns with
respect to all Transfer Taxes. In addition, each Stockholder acknowledges that
he, and not the Company, OEI or the Surviving Corporation, will pay all Taxes
due upon receipt of the consideration payable to the Stockholder pursuant to
Article II.

the Services Agreement dated effective as of March 5, 1993, between the Company

PC and its shareholders and each such document is in full force and effect on
the date hereof.

        Section 11.17. SUSPENSION AND TERMINATION OF SHAREHOLDERS AGREEMENT. The
outstanding shares of the Company Common Stock are subject to the Shareholders
Agreement which provides, INTER ALIA, options to purchase and to sell shares of
the Company Common Stock upon the occurrence of certain events specified

        Company shall notify each of the parties to the Shareholders Agreement
        that the provisions of this Section 11.17 have terminated.

By their execution and delivery of this Agreement, pursuant to Section 28 of the
Shareholders Agreement, the Company and the Stockholders (who hold 100% of the
shares of Capital Stock subject to the Shareholders Agreement) hereby amend the
Shareholders Agreement as set forth in this Section 11.17.

        Section 11.18. ERRORS AND OMISSIONS INSURANCE. Until the third

                                          TERMINATION

        Section 12.01. TERMINATION OF THIS AGREEMENT.

               (a) This Agreement may be terminated at any time prior to the
        Closing solely:

                       (i) by the mutual written consent of OEI and the Company;

                       (ii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if the transactions
               contemplated by this Agreement to take place at the Closing shall
               not have been consummated by October 31, 1998, unless


                                              19
<PAGE>
               the failure of such transactions to be consummated results from
               the willful failure of the Party (or in the case of the
               Stockholders and the Company, any of them) seeking to terminate
               this Agreement to perform or adhere to any agreement required
               hereby to be performed or adhered to by that Party prior to or at
               the Closing or thereafter on the IPO Closing Date;

                       (iii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if a material breach or
               default shall be made by the other Party (or in the case of the
               Stockholders and the Company, any of them) in the observance or
               in the due and timely performance of any of the covenants,
               agreements or conditions contained herein; or

                       (iv) by OEI if it is entitled to do so as provided in
               Section 6.07;

               (b) This Agreement may be terminated after the Closing solely:

                       (i) by OEI or the Company if the Underwriting Agreement
               is terminated pursuant to its terms after the Closing and prior
               to the consummation of the IPO; or

                       (ii) automatically and without action on the part of any
               party hereto if the IPO is not consummated within 15 Business
               Days after the date of the Closing.

               (c) If this Agreement is terminated pursuant to this Section
        12.01, the Merger will be deemed for all purposes to have been abandoned
        and of no force or effect. If this Agreement is terminated pursuant to
        this Section 12.01 after the Certificate of Merger has been filed with
        the Secretary of State of the State of New Jersey, but before the IPO
        has been consummated, OEI will take all actions that Counsel for the
        Company and the Stockholders advises OEI are required by the applicable
        laws of the State of New Jersey to rescind the Merger.

        Section 12.02. LIABILITIES IN EVENT OF TERMINATION. If this Agreement is
terminated pursuant to Section 12.01, there shall be no liability or obligation
on the part of any Party except (a) as provided in Section 11.07, (b) to the
extent that such liability is based on the breach of that Party of any of its or
his representations, warranties or covenants set forth in of this Agreement.

an amount equal to the difference between $4,521,905 and the amount, if any, by

        immediately prior to the Effective Time will be converted into one share
        of Common Stock, par value $1.00 per share, of the Surviving
        Corporation, and the shares of Common Stock of the Surviving Corporation
        issued on such conversion will constitute all the issued and outstanding
        shares of Capital Stock of the Surviving Corporation.

Each holder of a certificate representing shares of Company Common Stock
immediately prior to the Effective Time will, as of the Effective Time and
thereafter, cease to have any rights respecting those shares other than the
right to receive, without interest, the Initial Merger Consideration and the
additional cash, if any, owing with respect to those shares as provided in
Section 2.06.

        Section 2.05.  DELIVERY, EXCHANGE AND PAYMENT.

               (a) At or after the Effective Time: (i) each Stockholder, as the
        holder of certificates representing shares of Company Common Stock,
        will, on surrender of his certificates to OEI (or any agent which may be
        appointed by OEI for purposes of this Section 2.05), receive, and OEI
        will pay and issue to each Stockholder, in each case subject to the
        provisions of Section 2.06, the Initial Merger Consideration; and (ii)
        until any certificate representing Company Common Stock has been
        surrendered and replaced pursuant to this


                                              6
<PAGE>
        Section 2.05, that certificate will, for all purposes, be deemed to
        evidence ownership of the number of whole shares of OEI Common Stock
        included in the Initial Merger Consideration payable in respect of that
        certificate pursuant to Section 2.04. All shares of OEI Common Stock
        issuable in the Merger will be deemed for all purposes to have been
        issued by OEI at the Effective Time. All cash included in the Initial
        Merger Consideration shall be paid by OEI's company checks, certified or
        official bank checks, or wire transfers, at OEI's option. In the case of
        wire transfers, the transfers shall be to accounts designated by the
        respective Stockholders at least five Business Days before the IPO
        Closing Date.

               (b) Each Stockholder will deliver to OEI (or any agent that may
        be appointed by OEI for purposes of this Section 2.05), on or before the
        IPO Closing Date, the certificates representing Company Common Stock
        owned by the Stockholder, duly endorsed in blank by him, or accompanied
        by stock powers duly executed by him in blank, and with all necessary
        transfer tax and other revenue stamps, acquired at his expense, affixed
        and canceled. In the event this Agreement is terminated pursuant to
        Article XII prior to the Effective Time, OEI or its agent will return
        all such certificates and other documents to the Stockholders. Each
        Stockholder shall cure any deficiencies in the endorsement of the
        certificates or other documents of conveyance respecting, or in the
        stock powers accompanying, the certificates representing Company Common
        Stock delivered by him.

               (c) No dividends (or interest) or other distributions declared or
        earned after the Effective Time with respect to OEI Common Stock and
        payable to the holders of record thereof after the Effective Time will
        be paid to the holder of any unsurrendered certificates representing
        shares of Company Common Stock for which shares of OEI Common Stock have
        been issued in the Merger until the unsurrendered certificates are
        surrendered as provided herein, but (i) on such surrender, OEI will
        cause to be paid, to the Person in whose name the certificates
        representing such shares of OEI Common Stock shall then be issued, the
        amount of dividends or other distributions previously paid with respect
        to such whole shares of OEI Common Stock with a record date, or which
        have accrued, subsequent to the Effective Time, but prior to surrender,
        and the amount of any cash payable to such Person for and in lieu of
        fractional shares pursuant to Section 2.06 and (ii) at the appropriate
        payment date or as soon as practicable thereafter, OEI will cause to be
        paid to that Person the amount of dividends or other distributions with
        a record date, or which have been accrued, subsequent to the Effective
        Time, but which are not payable until a date subsequent to surrender,
        which are payable with respect to such number of whole shares of OEI
        Common Stock, subject in all cases to any applicable escheat laws. No
        interest will be payable with respect to the payment of such dividends
        or other distributions (or cash for and in lieu of fractional shares) on
        surrender of outstanding certificates.

        Section 2.06. FRACTIONAL SHARES. Notwithstanding any other provision of
this Article II, no fractional shares of OEI Common Stock will be issued, and
any Stockholder otherwise entitled to receive a fractional share of OEI Common
Stock but for this Section 2.06 will instead be entitled to receive a cash
payment for and in lieu thereof in the amount (rounded to the nearest whole
cent) equal to that Person's fractional interest in a share of OEI Common Stock
multiplied by $12.

        Section 2.07.  CONTINGENT CONSIDERATION AND RELATED ESCROW.

               (a) ESCROW. At the Effective Time, in addition to the Initial
        Merger Consideration to be delivered to the Stockholders: (i) OEI shall
        deposit with an escrow agent to be jointly selected by OEI and the
        Stockholders (the "ESCROW AGENT"), 654,099 shares of OEI Common Stock
        (the "CONTINGENT STOCK CONSIDERATION") and $3,363,939 in cash (the
        "CONTINGENT CASH CONSIDERATION" and, together with the Contingent Stock
        Consideration, the "CONTINGENT MERGER CONSIDERATION"); and (ii) OEI and
        the Stockholders shall enter into an Escrow Agreement (the "ESCROW
        AGREEMENT") with the Escrow Agent, which shall be in the form of Exhibit
        2.07, with its blanks appropriately completed; provided, however, that
        OEI may at any time on or before the date of Closing elect to substitute
        for all or any part of the Contingent Stock Consideration cash in an
        amount equal to $12 times the number of shares of OEI Common Stock for
        which OEI elects to substitute cash.

               (b) STOCKHOLDERS' RIGHTS. The Contingent Stock Consideration
        shall: (i) be issued and outstanding shares of OEI Common Stock and
        shall appear as such on the balance sheet of OEI; (ii) be entitled, PRO
        RATA with all other holders of OEI Common Stock, to all dividends
        declared with respect to the OEI Common Stock; and (iii) have voting
        rights equal to the voting rights of all other issued and outstanding
        shares of OEI Common Stock. Any cash dividends which may be declared and
        paid by OEI in respect of the Contingent Stock Consideration shall be
        paid by OEI to the Escrow Agent and shall become additional Contingent
        Cash Consideration. All shares of OEI Common Stock payable in respect of
        the Contingent Stock Consideration as a result of any stock split or
        other non-cash distribution (including a stock dividend) shall be held
        by the Escrow Agent and shall become additional Contingent Stock
        Consideration. The Escrow Agent shall vote the Contingent Stock
        Consideration during the time such shares are held in escrow pursuant to
        the written instructions of the Stockholders, in accordance with their
        respective Pro Rata Shares.

               (c) INVESTMENTS, INTEREST AND DIVIDENDS. All cash from time to
        time held in escrow shall be invested in bonds intended to be free of
        federal income tax or in bond funds invested primarily in such bonds, as
        mutually agreed by OEI and the Stockholders. The term "Contingent Cash
        Consideration" shall include all cash existing at any time in escrow,
        including interest, cash dividends and other cash proceeds paid on or
        with respect to Contingent Cash Consideration or Contingent Stock
        Consideration. The term "Contingent Stock Consideration" shall include
        all shares of OEI Common Stock held of record at any time by the Escrow
        Agent, including such shares issued as a result of any stock split or
        other non-cash distribution (including a stock dividend.)

               (d) ASSIGNMENT. The Stockholders may grant or assign to one or
        more employees of the Company the right to purchase or receive all or
        any part of the Contingent Merger Consideration upon its distribution
        from escrow, subject, in the case of Contingent Stock Consideration, to
        compliance with all applicable federal and state securities laws;
        PROVIDED, HOWEVER, that any such employee will take any Contingent Stock
        Consideration


                                              8
<PAGE>
        granted or assigned to him hereunder subject to the restrictions on
        transfer contained in Section 11.02.

        Section 2.08.  DISBURSEMENT FROM ESCROW.

               (a) INSTRUCTIONS TO ESCROW AGENT. OEI and the Stockholders agree
        to provide the Escrow Agent, from time to time, with joint written
        instructions to distribute the Contingent Merger Consideration in
        accordance with the provisions set forth in this Section 2.08.

               (b) EARN-OUT PERIOD. The Contingent Merger Consideration will be
        distributed to the Stockholders or returned to OEI, in each case in
        whole or in part, based on the Company's achievement of, or failure to
        achieve, within the three-year period beginning January 1, 1998 (the
        "EARNOUT PERIOD"), designated levels of Cumulative Post-Closing EBITDA
        (as defined below). The Earnout Period shall be divided into three
        successive one-year periods (each an "EARNOUT YEAR"), the first of which
        shall begin on January 1, 1998, with each Earnout Year thereafter to
        begin on the next succeeding anniversary of that day.

               (c) INTERIM DISTRIBUTIONS. If at the end of any Earnout Year,
        Cumulative Post-Closing EBITDA through the end of that Earnout Year
        exceeds the product of (x) $3,833,015 times (y) the number of full
        Earnout Years lapsed through the end of that Earnout Year, then there
        shall be distributed to the Stockholders a portion of the Contingent
        Merger Consideration (the "INTERIM DISTRIBUTION") determined by:

                       (i) subtracting (x) the product of (a) $3,833,015 times
               (b) the number of full Earnout Years lapsed through the end of
               the most recently ended Earnout Year, from (y) Cumulative
               Post-Closing EBITDA for that portion of the Earnout Period ended
               on the most recently completed Earnout Year;

                       (ii) multiplying $11,213,127 by a fraction the numerator
               of which is the result of the calculation made under clause (i)
               above and the denominator of which is $6,727,875; and

                       (iii) subtracting from that result the sum of (x) all
               Contingent Cash Consideration previously distributed to the
               Stockholders and (y) $12 multiplied by the number of shares of
               Contingent Stock Consideration, if any, previously distributed to
               the Stockholders;


                                              9
<PAGE>
        in which case:

                       (i) the amount of Contingent Cash Consideration
               distributed to the Stockholders shall equal 30% (subject to
               appropriate adjustment if OEI elects to substitute cash for any
               Contingent Stock Consideration) of the Interim Distribution; and

                       (ii) the number of shares of Contingent Stock
               Consideration distributed to the Stockholders shall be determined
               by first (x) subtracting (a) the amount of the Contingent Cash
               Consideration distributable to the Stockholders under clause (i)
               above from (b) the amount of the Interim Distribution, and (y)
               then dividing that result by $12.

        Any Interim Distribution shall be payable and issuable to the
        Stockholders PRO RATA in accordance with their respective Pro Rata
        Shares.

               (d) CUMULATIVE POST-CLOSING EBITDA. As used herein, the term
        "CUMULATIVE POST-CLOSING EBITDA" means for any period beginning on
        January 1, 1998, and ending on any specified date, consolidated earnings
        (including engineering income) of the Company and the Subsidiary before
        interest expense, foreign, federal and state income and franchise taxes
        (to the extent based on or measured by income), and depreciation and
        amortization expense, all determined in accordance with generally
        accepted accounting principles, adjusted to:

                       (i) eliminate any charges to the Company's earnings in
               respect of allocations of indirect corporate overhead expense
               (but not expenses directly attributable to the Company or its
               operations, such as charges for insurance) of OEI;

                       (ii) reflect a capital charge (computed at an annual rate
               equal to the average rate OEI is then paying on outstanding
               advances under its primary line of credit facility with a bank,
               plus 1%) for all funds advanced to the Company by OEI (x) for
               working capital purposes or (y) to fund capital expenditures of
               the Company for the purpose of improving, expanding or adding to
               (but not maintaining at its present level) the Company's
               property, plant and equipment;

                       (iii) reflect a 1% charge for all funds advanced to the
               Company under any bank credit facility guaranteed by OEI or in
               respect of which OEI is otherwise contingently liable;

                       (iv) eliminate any charges to the Company's earnings
               resulting from the Company being required to perform under any
               guaranty of any third party obligation if the guaranty is
               unrelated to the Company's business;


                                              10
<PAGE>
                       (v) exclude non-operating income and losses, such as, by
               way of example only, investment income and gains and losses from
               dispositions of capital assets; and

                       (vi) exclude all other non-recurring or extraordinary
               items of gain or loss.

        Section 2.09.  TERMINATION OF ESCROW.

               (a) INSTRUCTIONS TO ESCROW AGENT. OEI and the Stockholders agree
        to provide the Escrow Agent with joint written instructions to
        distribute the Contingent Merger Consideration in accordance with the
        provisions set forth in this Section 2.09.

               (b) EARLY TERMINATION OF EARN-OUT. If before the expiration of
        the Earnout Period:

                       (i) the Company's Cumulative Post-Closing EBITDA reaches
               or exceeds an amount equal to $18,226,920 then all of the
               previously undistributed Contingent Merger Consideration, plus
               all previously undistributed interest and dividends earned on it
               while in escrow, shall be distributed to the Stockholders, and
               the escrow shall terminate. The distribution on any such
               termination shall be payable and issuable to the Stockholders PRO
               RATA in accordance with their respective Pro Rata Shares.

                       (ii) Gulsby voluntarily terminates his employment with
               the Company or is discharged for "Cause" (as such term is defined
               in the New Employment Agreement), then all Contingent Cash
               Consideration and all Contingent Stock Consideration (including
               all interest, dividends and other proceeds paid on or with
               respect to amounts in escrow) which are then in escrow, shall be
               distributed to OEI, and the escrow shall terminate. Neither the
               death nor disability of Gulsby shall cause such an early
               termination of the escrow.

               (c) EXPIRATION OF EARNOUT PERIOD. If upon the expiration of the
        Earnout Period, the Company's Cumulative Post-Closing EBITDA has not
        reached or exceeded an amount equal to $18,226,920 then all previously
        undistributed Contingent Cash Consideration and all Contingent Stock
        Consideration shall be distributed to OEI, and the escrow shall
        terminate.

        Section 2.10. OEI COVENANTS DURING THE EARNOUT PERIOD. OEI agrees that
from the time of Closing through the first to occur of the expiration of the
Earnout Period or the termination of the escrow as provided in Section 2.09
above, OEI will not cause or permit the Company to:

               (a)     be liquidated or dissolved;

               (b)     sell all or substantially all of its assets;


                                              11
<PAGE>
               (c) relocate the Company's principal office and fabrication
        facility from its present location;

               (d) merge or consolidate with or into any corporation or other
        business entity; or

               (e) acquire another business entity or the assets or operations
        of another business entity.

        Except as specifically prohibited above in this Section 2.10, the
Company may at any time change or discontinue any of its present or future
assets or operations, or may close any of its present or future offices or
manufacturing facilities, or undertake new operations, or may take any and all
other steps which the Company's Board of Directors, in its judgment, shall deem
advisable and in the best interest of the Company, and if any such action
adversely affects Cumulative Post-Closing EBITDA, the Stockholders shall have no
claim or recourse by reason of such action.

        Section 2.11. ASSUMPTION OF CERTAIN OBLIGATIONS. As additional
consideration for the shares of the Company Common Stock, effective as of the
Effective Time, OEI will assume the obligation of the Stockholders to pay the
outstanding balance as of December 31, 1997, of the loans from the Company to
the Stockholders in the aggregate amount of $3,120,571.

        Section 2.12. PENDING JUDGMENT. If, prior to the IPO Closing Date, the
Company is released from all liability with respect to the judgment against the
Company in the cause reflected on the Current Balance Sheet and described in
footnote 9 to the Initial Financial Statements (the "Pending Judgment"), for
less than the amount of the Judgment Reserve, then the amount by which the
Judgment Reserve exceeds the amount paid to settle the Pending Judgment and to
obtain such release will be added to the cash portion of the Initial Merger
Consideration. If the Company is released from all liability in respect of the
Pending Judgment within three months after the date of the Closing for less than
the amount of the Judgment Reserve, then the amount by which the Judgment
Reserve exceeds the amount paid to settle the Pending Judgment and to obtain
such release will be paid to the Stockholders in accordance with their
respective Pro Rate Shares. If the Pending Judgment is not settled and released
within three months after the IPO Closing Date, the Company shall pay and obtain
the release of the Pending Judgment and there shall be no adjustment to the
Merger Consideration.

             THE CLOSING AND CONDITIONS TO CLOSING AND CONSUMMATION

        Section 7.01.  THE CLOSING AND CERTAIN CONDITIONS.

               (a) THE CLOSING. On or before the IPO Pricing Date, the Parties
        will take all actions necessary to (i) effect the Merger on the IPO
        Closing Date (including, as permitted by the Business Corporation Act,
        (A) the execution of a Certificate of Merger meeting the requirements of
        the Business Corporation Act and providing that the Merger will become
        effective on the IPO Closing Date and (B) the filing of the Certificate
        of Merger with the Secretary of State of the State of Texas), (ii)
        verify the existence and ownership of the certificates evidencing the
        Company Common Stock to be exchanged for the Initial Merger
        Consideration pursuant to Section 2.05, and (iii) satisfy the document
        delivery requirements to which the obligations of the Parties to effect
        the Merger and the other transactions contemplated hereby are
        conditioned by the provisions of this Article VII (all those actions
        collectively being the "CLOSING"). The Closing will take place at the
        offices of Porter & Hedges, L.L.P., 700 Louisiana, Houston, Texas at

        completed on or before the IPO Closing Date, including the surrender of
        the Company Common Stock in exchange for the Initial Merger
        Consideration will be closed or completed, as the case may be. During

        be terminated by the parties only pursuant to Section 12.01 (b)(i).

               (b) CERTAIN CONDITIONS TO THE OBLIGATIONS OF THE COMPANY AND THE
        STOCKHOLDERS. The obligations of the Company and the Stockholders with
        respect to the actions to be taken by them at or before the Closing are
        subject to the satisfaction on or before the date of the Closing, or
        waiver by them pursuant to Section 11.05, of all the conditions set
        forth in Sections 7.02(a) and 7.03. The obligations of the Stockholders
        with respect to the actions to be taken on the IPO Closing Date are
        subject to the satisfaction on that date of the following conditions:
        (i) each of the Transferors' Agreement, the New Employment Agreement and
        the Escrow Agreement then shall be in full force and effect; and (ii)
        all the conditions set forth in Sections 7.02(b) and 7.03.

               (c) CERTAIN CONDITIONS TO THE OBLIGATIONS OF OEI AND NEWCO. The
        obligations of OEI and Newco with respect to actions to be taken by them
        at or before the Closing are subject to the satisfaction on or before

        the following conditions: (i) the Company shall have delivered to OEI a
        copy of the articles or certificate of incorporation, as amended to the
        date of the Closing


                                              15
<PAGE>
        and certified by the Secretary of State of the State of Texas as of a
        Current Date, of the Company; and (ii) all the conditions set forth in
        Sections 7.02(a) and 7.04(a).

               (d) CERTAIN CONDITIONS TO BE MET BY IPO CLOSING DATE. The
        obligations of OEI and Newco with respect to the actions to be taken on
        the IPO Closing Date are subject to the satisfaction on that date of the
        following conditions: (i) each of the Transferors' Agreement, the New
        Employment Agreement, the Escrow Agreement, the Lease Agreement and the
        Right of First Refusal Agreement then shall be in full force and effect;
        and (ii) all the conditions set forth in Sections 7.02(b) and 7.04(b).

               (e) INCORPORATION OF ARTICLE VII OF UNIFORM PROVISIONS. The text
        of Article VII of the Uniform Provisions hereby is incorporated herein
        by this reference.

                                  ARTICLE VIII

                     COVENANTS FOLLOWING THE EFFECTIVE TIME

        Section 8.01. OF EACH PARTY OTHER THAN THE COMPANY. From and after the
Effective Time, subject to the waiver provisions of Section 11.05, each Party
(other than the Company) will comply with each covenant for which provision is

is incorporated herein by this reference) to be performed or observed by that
Party.

                                   ARTICLE IX

                                 INDEMNIFICATION

Article IX of the Uniform Provisions hereby is incorporated herein by this
reference.

                                    ARTICLE X

                           LIMITATIONS ON COMPETITION

        Section 10.01. PROHIBITED ACTIVITIES. Each Stockholder identified on
Schedule 10.01 (each a "Restricted Stockholder") and, in the case of paragraphs
(b) and (d) below of this Section 10.01, each Stockholder, severally agrees that
he will not during the period beginning on the date hereof and ending on the
third anniversary of the date hereof, directly or indirectly, for any reason,
for his own account or on behalf of or together with any other Person:

               (a) engage as an officer, director or in any other managerial
        capacity or as an owner, co-owner or other investor of or in, whether as
        an employee, independent contractor, consultant or advisor, any business
        engaged in the Practice of Engineering in competition with the Company,
        any Company Subsidiary or OEI or any Subsidiary of OEI (OEI and its


                                              16
<PAGE>
        Subsidiaries collectively being called "OEI" for purposes of this
        Article X) within any territory surrounding any office or facility (each
        a "facility") in which any of the Company or the Company Subsidiaries
        was engaged in business on the date hereof or immediately prior to the
        Effective Time (for purposes of this Article X, the territory
        surrounding a facility shall be: (i) the city, town or village in which
        the facility is located, (ii) the county or parish in which the facility
        is located, (iii) the counties or parishes contiguous to the county or
        parish in which the facility is located, and (iv) the area located
        within 100 miles of the facility, all of such locations being herein
        collectively called the "TERRITORY");

               (b) call on any natural Person who is at that time employed by
        the Company, any Company Subsidiary or OEI with the purpose or intent of
        attracting that person from the employ of the Company, any Company
        Subsidiary or OEI, provided that a Stockholder may call on and hire any
        of his Immediate Family Members;

               (c) call on any Person that at that time is, or at any time
        within one year prior to that time was, a customer of the Company, any
        Company Subsidiary or OEI within the Territory, (i) for the purpose of
        soliciting or selling any product or service in competition with the
        Company, any Company Subsidiary or OEI within the Territory and (ii)
        with the knowledge of the customer relationship; or

               (d) call on any OEI Acquisition Candidate, with the knowledge of
        that Person's status as an OEI Acquisition Candidate, for the purpose of
        acquiring that Person or arranging the acquisition of that Person by any
        Person other than OEI.

Notwithstanding the foregoing, any Restricted Stockholder may own and hold as a
passive investment up to 1% of a class of the outstanding Capital Stock of a
competing Entity if that class of Capital Stock is publicly traded.

        Section 10.02. DAMAGES. Because of the difficulty of measuring economic
losses to OEI as a result of any breach by a Restricted Stockholder or any other
Stockholder of his covenants in Section 10.01, and because of the immediate and
irreparable damage that could be caused to OEI for which it would have no other
adequate remedy, each Restricted Stockholder (and, in the case of paragraphs (b)
and (d) of Section 10.01, each Stockholder) agrees that OEI may enforce the
provisions of Section 10.01 by injunctions and restraining orders against the
Restricted Stockholder or Stockholder, as the case may be, if he breaches any of
those provisions.

        Section 10.03. REASONABLE RESTRAINT. The Parties each agree that
Sections 10.01 and 10.02 impose a reasonable restraint on the Restricted
Stockholder or Stockholders, as the case may be, in light of the activities and
business of OEI on the date hereof, the current business plans of OEI and the
investment by each Stockholder in OEI as a result of the Merger.

        Section 10.04. SEVERABILITY; REFORMATION. The covenants in this Article
X are severable and separate. The unenforceability of any specific covenant in
this Article X is not intended by any Party to, and shall not, affect the
provisions of any other covenant in this Article X. If any court of


                                              17
<PAGE>
competent jurisdiction determines that the scope, time or territorial
restrictions set forth in Section 10.01 are unreasonable as applied to any
Restricted Stockholder or Stockholder, as the case may be, the Parties,
including the Restricted Stockholder or Stockholder in question, acknowledge
their mutual intention and agreement that those restrictions be enforced to the
fullest extent the court deems reasonable, and thereby shall be reformed to that
extent as applied to that Restricted Stockholder or Stockholder, as the case may
be, and any other Restricted Stockholder or Stockholder, as the case may be,
similarly situated.

        Section 10.05. INDEPENDENT COVENANT. All the covenants in this Article X
are intended by each Party to, and shall, be construed as an agreement
independent of any other provision in this Agreement, and the existence of any
claim or cause of action of any Restricted Stockholder or Stockholder against
OEI, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by OEI of any covenant in this Article X. It is
specifically agreed that the period specified in Section 10.01 shall be computed
in the case of each Restricted Stockholder and Stockholder by excluding from
that computation any time during which the Restricted Stockholder or Stockholder
is in violation of any provision of Section 10.01. The covenants contained in
this Article X shall not be affected by any breach of any other provision of
this Agreement by any Party.

        Section 10.06. MATERIALITY. The Company and each Stockholder, severally
and not jointly with any other Person, hereby agree that this Article X is a
material and substantial part of the transactions contemplated by this
Agreement.

                                   ARTICLE XI

                               GENERAL PROVISIONS

        Section 11.01. TREATMENT OF CONFIDENTIAL INFORMATION. Each Party will
comply with each covenant for which provision is made in Section 11.01 of the
Uniform Provisions (the text of which Section hereby is incorporated herein by
this reference) to be performed or observed by that Party.

        Section 11.02. RESTRICTIONS ON TRANSFERS OF OEI COMMON STOCK.

               (a) During the two-year period ending on the second anniversary
        of the IPO Closing Date (the "RESTRICTED PERIOD"), no Stockholder
        voluntarily will: (i) sell, assign, exchange, transfer, encumber,
        pledge, distribute, appoint or otherwise dispose of (A) any shares of
        OEI Common Stock (including the Contingent Stock Consideration) received
        by any Stockholder in the Merger or (B) any interest in (including any
        option to buy or sell) any such shares of OEI Common Stock, in whole or
        in part, and OEI will have no obligation to, and shall not, treat any
        such attempted transfer as effective for any purpose; or (ii) engage in
        any transaction, whether or not with respect to any shares of OEI Common
        Stock or any interest therein, the intent or effect of which is to
        reduce the risk of owning the shares of OEI Common Stock acquired
        pursuant to Section 2.04 (including, for example engaging in put,


                                              18
<PAGE>
        call, short-sale, straddle or similar market transactions); PROVIDED,
        HOWEVER, that this Section 11.02 shall not restrict (x) any transfer of
        OEI Common Stock acquired by a Stockholder pursuant to Section 2.04 to
        any of that Stockholder's Related Persons who agree in writing to be
        bound by the provisions of Section 11.01 and this Section 11.02 or (y)
        any transfer pursuant to Section 2.07(d) of Contingent Stock
        Consideration to an employee of the Company who agrees in writing to be
        bound by the provisions of Section 11.01 and this Section 11.02. The
        certificates evidencing the OEI Common Stock delivered to each
        Stockholder pursuant to Section 2.05 will bear a legend substantially in
        the form set forth below and containing such other information as OEI
        may deem necessary or appropriate:

               EXCEPT PURSUANT TO THE TERMS OF THE AGREEMENT AND PLAN OF
               REORGANIZATION AMONG THE ISSUER, THE HOLDER OF THIS CERTIFICATE
               AND THE OTHER PARTIES THERETO, THE SHARES REPRESENTED BY THIS
               CERTIFICATE MAY NOT BE VOLUNTARILY SOLD, ASSIGNED, EXCHANGED,
               TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR
               OTHERWISE DISPOSED OF, AND THE ISSUER SHALL NOT BE REQUIRED TO
               GIVE EFFECT TO ANY ATTEMPTED VOLUNTARY SALE, ASSIGNMENT,
               EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION,
               APPOINTMENT OR OTHER DISPOSITION OF ANY OF THOSE SHARES, DURING
               THE TWO-YEAR PERIOD ENDING ON [DATE THAT IS THE SECOND
               ANNIVERSARY OF THE IPO CLOSING DATE] (THE "RESTRICTED PERIOD").
               ON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE
               ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP
               ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE EXPIRATION OF THE
               RESTRICTED PERIOD.

               (b) Each Stockholder, severally and not jointly with any other
        Person, (i) acknowledges that the shares of OEI Common Stock to be
        delivered to him pursuant to Section 2.04 (A) have not been and, except
        pursuant to the Registration Rights Agreement, if applicable, will not
        be registered under the Securities Act and therefore may not be resold
        by him without compliance with the Securities Act and (B) will, as a
        result of their restrictions on transferability which are imposed by
        this Agreement during the Restricted Period, have a value materially
        less at the Effective Time than the value of then freely tradeable
        shares of OEI Common Stock, and (ii) covenants that none of the shares
        of OEI Common Stock issued to him pursuant to Section 2.04 will be
        offered, sold, assigned, pledged, hypothecated, transferred or otherwise
        disposed of except after full compliance with all the applicable
        provisions of the Securities Act and the rules and regulations of the
        SEC and applicable state securities laws and regulations. All
        certificates evidencing shares of OEI Common Stock issued pursuant to
        Section 2.04 will bear the following legend in addition to the legend
        prescribed by Section 11.02(a):

               THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE

               OTHERWISE TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THAT ACT
               AND OTHER APPLICABLE SECURITIES LAWS.


                                              19

        agreement of that Stockholder with the Underwriter to the effect set
        forth in Section 11.02(a).

        Section 11.03. BROKERS AND AGENTS. The Stockholders jointly and
severally represent and warrant to OEI that the Company has not directly or
indirectly employed or become obligated to pay any broker or similar agent in
connection with the transactions contemplated hereby and agree, without regard

against all Damage Claims arising out of claims for any and all fees and
commissions of brokers or similar agents employed or promised payment by the
Company.

        Section 11.04. ASSIGNMENT; NO THIRD PARTY BENEFICIARIES. This Agreement
and the rights of its Parties may not be assigned (except by operation of law)
and shall be binding on and inure to the benefit of the Parties, the successors
of OEI, and the heirs and legal representatives of the Stockholders (and, in the
case of any trust, the successor trustees of the trust). Neither this Agreement
nor any other Transaction Document is intended, or shall be construed, deemed or
interpreted, to confer on any Person not a party hereto or thereto any rights or
remedies hereunder or thereunder, except as provided in Section 6.05(b) or

the documents delivered pursuant to it constitute the entire agreement and
understanding among the Parties and supersede all prior agreements and

right hereunder may be waived, if, but only if, the amendment, modification,
supplement or waiver is in writing and signed by the Majority Stockholders, the
Company and OEI. The waiver of any of the terms and conditions of this Agreement
shall not be construed or interpreted as, or deemed to be, a waiver of any of
its other term or conditions.

        Section 11.06. COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which will be an original, but all of which together will
constitute one and the same instrument.

                                   TERMINATION

        Section 12.01. TERMINATION OF THIS AGREEMENT.

               (a)     This Agreement may be terminated at any time prior to the
 Closing solely:

                       (i)   by the mutual written consent of OEI and the 
               Company;

                       (ii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if the transactions
               contemplated by this Agreement to take place at the Closing shall
               not have been consummated by October 31, 1998, unless the failure
               of such transactions to be consummated results from the willful
               failure of the Party (or in the case of the Stockholders and the
               Company, any of them) seeking to terminate this Agreement to
               perform or adhere to any agreement required hereby to be
               performed or adhered to by that Party prior to or at the Closing
               or thereafter on the IPO Closing Date;

                       (iii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if a material breach or
               default shall be made by the other Party (or in the case of the
               Stockholders and the Company, any of them) in the observance or
               in the due and timely performance of any of the covenants,
               agreements or conditions contained herein; or

                       (iv) by OEI if it is entitled to do so as provided in
               Section 6.07;

               (b) This Agreement may be terminated after the Closing solely:

                       (i) by OEI or the Company if the Underwriting Agreement
               is terminated pursuant to its terms after the Closing and prior
               to the consummation of the IPO; or

                       (ii) automatically and without action on the part of any
               party hereto if the IPO is not consummated within 15 Business
               Days after the date of the Closing.

               (c) If this Agreement is terminated pursuant to this Section
        12.01, the Merger will be deemed for all purposes to have been abandoned
        and of no force or effect. If this Agreement is terminated pursuant to
        this Section 12.01 after the Certificate of Merger has been filed with
        the Secretary of State of the State of Texas, but before the IPO has
        been consummated, OEI will take all actions that Counsel for the Company
        and the Stockholders advises OEI are required by the applicable laws of
        the State of Texas to rescind the Merger.

on the part of any Party except (a) as provided in Section 11.07, (b) to the
extent that such liability is based on the breach of that Party of any of its or
his representations, warranties or covenants set forth in of this Agreement.

        IN WITNESS WHEREOF, the Parties have executed this Agreement as of the
date first above written.

        Time, but which are not payable until a date subsequent to surrender,
        which are payable with respect to such number of whole shares of OEI
        Common Stock, subject in all cases to any applicable escheat laws. No
        interest will be payable with respect to the payment of such dividends

        effective on the IPO Closing Date and (B) the filing of the Certificate
        of Merger with the Secretary of State of the State of Texas), (ii)
        verify the existence and ownership of the certificates evidencing the
        Company Common Stock to be exchanged for the Merger Consideration
        pursuant to Section 2.05, and (iii) satisfy the document delivery
        requirements to which the obligations of the Parties to effect the
        Merger and the other transactions contemplated hereby are conditioned by
        the provisions of this Article VII (all those actions collectively being
        the "CLOSING"). The Closing will take place at the offices of Porter &
        Hedges, L.L.P., 700 Louisiana, Houston, Texas at 10:00 a.m., Houston
        time, or at such later time on the IPO Pricing Date as OEI shall specify
        by written notice to John W. White. The actions taken at the Closing
        will not include the completion of either the Merger or the delivery of
        the Company Common Stock or the Merger Consideration pursuant to Section
        2.05. Instead, on the IPO Closing Date, the Certificate of Merger will
        become effective pursuant to Section 2.02, and all transactions
        contemplated by this Agreement to be closed or completed on or before
        the IPO Closing Date, including the surrender of the Company Common
        Stock in exchange for the Merger Consideration will be closed or
        completed, as the case may be. During the period from the Closing to the
        IPO Closing Date, this Agreement may be terminated by the parties only
        pursuant to Section 12.01 (b)(i).

               (b) CERTAIN CONDITIONS TO THE OBLIGATIONS OF THE COMPANY AND THE
        STOCKHOLDERS. The obligations of the Company and the Stockholders with
        respect to the actions to be taken by them at or before the Closing are
        subject to the satisfaction on or before the date of the Closing, or
        waiver by them pursuant to Section 11.05, of all the conditions set
        forth in


                                              9

        conditions set forth in Sections 7.02(a) and 7.04(a).

        full force and effect; and (ii) all the conditions set forth in Sections
        7.02(b) and 7.04(b).

               (e) INCORPORATION OF ARTICLE VII OF UNIFORM PROVISIONS. The text
        of Article VII of the Uniform Provisions hereby is incorporated herein
        by this reference.

                                  LIMITATIONS ON COMPETITION

        Section 10.01. PROHIBITED ACTIVITIES. Each Stockholder identified on
Schedule 10.01 (each a "Restricted Stockholder") and, in the case of paragraphs
(b) and (d) below of this Section 10.01, each Stockholder, severally agrees that
he will not during the period beginning on the date hereof and ending on the
third anniversary of the date hereof, directly or indirectly, for any reason,
for his own account or on behalf of or together with any other Person:

               (a) engage as an officer, director or in any other managerial
        capacity or as an owner, co-owner or other investor of or in, whether as
        an employee, independent contractor, consultant or advisor, in any
        business engaged in the Practice of Engineering in competition with the
        Company, any Company Subsidiary or OEI or any Subsidiary of OEI (OEI and
        its Subsidiaries collectively being called "OEI" for purposes of this
        Article X) within any territory surrounding any office or facility (each
        a "facility") in which any of the Company or the Company Subsidiaries
        was engaged in business on the date hereof or immediately prior to the
        Effective Time (for purposes of this Article X, the territory
        surrounding a facility shall be: (i) the city, town or village in which
        the facility is located, (ii) the county or parish in which the facility
        is located, (iii) the counties or parishes contiguous to the county or
        parish in which the facility is located, and (iv) the area located
        within 100 miles of the facility, all of such locations being herein
        collectively called the "TERRITORY");

               (b) call on any natural Person who is at that time employed by
        the Company, any Company Subsidiary or OEI with the purpose or intent of
        attracting that person from the employ of the Company, any Company
        Subsidiary or OEI, provided that a Stockholder may call on and hire any
        of his Immediate Family Members;

               (c) call on any Person that at that time is, or at any time
        within one year prior to that time was, a customer of the Company, any
        Company Subsidiary or OEI within the Territory, (i) for the purpose of
        soliciting or selling any product or service in competition with the
        Company, any Company Subsidiary or OEI within the Territory and (ii)
        with the knowledge of the customer relationship; or

               (d) call on any OEI Acquisition Candidate, with the knowledge of
        that Person's status as an OEI Acquisition Candidate, for the purpose of
        acquiring that Person or arranging the acquisition of that Person by any
        Person other than OEI.

Notwithstanding the foregoing, any Restricted Stockholder may own and hold as a
passive investment up to 1% of a class of the outstanding Capital Stock of a
competing Entity if that class of Capital Stock is publicly traded.

           Section 10.02. DAMAGES. Because of the difficulty of measuring
economic losses to OEI as a result of any breach by a Restricted Stockholder or
any other Stockholder of his covenants in


                                              11
<PAGE>
Section 10.01, and because of the immediate and irreparable damage that could be
caused to OEI for which it would have no other adequate remedy, each Restricted
Stockholder (and, in the case of paragraphs (b) and (d) of Section 10.1, each
Stockholder) agrees that OEI may enforce the provisions of Section 10.01 by
injunctions and restraining orders against the Restricted Stockholder or
Stockholder, as the case may be, if he breaches any of those provisions.

        Section 10.03. REASONABLE RESTRAINT. The Parties each agree that
Sections 10.01 and 10.02 impose a reasonable restraint on the Restricted
Stockholder or Stockholders, as the case may be, in light of the activities and
business of OEI on the date hereof, the current business plans of OEI and the
investment by each Stockholder in OEI as a result of the Merger.

        Section 10.04. SEVERABILITY; REFORMATION. The covenants in this Article
X are severable and separate. The unenforceability of any specific covenant in
this Article X is not intended by any Party to, and shall not, affect the
provisions of any other covenant in this Article X. If any court of competent
jurisdiction determines that the scope, time or territorial restrictions set
forth in Section 10.01 are unreasonable as applied to any Restricted Stockholder
or Stockholder, as the case may be, the Parties, including the Restricted
Stockholder or Stockholder in question, acknowledge their mutual intention and
agreement that those restrictions be enforced to the fullest extent the court
deems reasonable, and thereby shall be reformed to that extent as applied to
that Restricted Stockholder or Stockholder, as the case may be, and any other
Restricted Stockholder or Stockholder, as the case may be, similarly situated.

        Section 10.05. INDEPENDENT COVENANT. All the covenants in this Article X
are intended by each Party to, and shall, be construed as an agreement
independent of any other provision in this Agreement, and the existence of any
claim or cause of action of any Restricted Stockholder or Stockholder against
OEI, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by OEI of any covenant in this Article X. It is
specifically agreed that the period specified in Section 10.01 shall be computed
in the case of each Restricted Stockholder and Stockholder by excluding from
that computation any time during which the Restricted Stockholder or Stockholder
is in violation of any provision of Section 10.01. The covenants contained in
this Article X shall not be affected by any breach of any other provision of
this Agreement by any Party.

        Section 10.06. MATERIALITY. The Company and each Stockholder, severally
and not jointly with any other Person, hereby agree that this Article X is a
material and substantial part of the transactions contemplated by this
Agreement.

                                          ARTICLE XI

                                      GENERAL PROVISIONS

        Section 11.01. TREATMENT OF CONFIDENTIAL INFORMATION. Each Party will
comply with each covenant for which provision is made in Section 11.01 of the
Uniform Provisions (the text of which Section hereby is incorporated herein by
this reference) to be performed or observed by that Party.

        Section 11.02. RESTRICTIONS ON TRANSFERS OF OEI COMMON STOCK.

               (a) During the two-year period ending on the second anniversary
        of the IPO Closing Date (the "RESTRICTED PERIOD"), no Stockholder
        voluntarily will: (i) sell, assign, exchange, transfer, encumber,
        pledge, distribute, appoint or otherwise dispose of (A) any shares of
        OEI Common Stock received by any Stockholder in the Merger or (B) any
        interest in (including any option to buy or sell) any such shares of OEI
        Common Stock, in whole or in part, and OEI will have no obligation to,
        and shall not, treat any such attempted transfer as effective for any
        purpose; or (ii) engage in any transaction, whether or not with respect
        to any shares of OEI Common Stock or any interest therein, the intent or
        effect of which is to reduce the risk of owning the shares of OEI Common
        Stock acquired pursuant to Section 2.04 (including, for example engaging
        in put, call, short-sale, straddle or similar market transactions);
        PROVIDED, HOWEVER, that this Section 11.02 shall not restrict any
        transfer of OEI Common Stock acquired by a Stockholder pursuant to
        Section 2.04 to any of that Stockholder's Related Persons who agree in
        writing to be bound by the provisions of Section 11.01 and this Section
        11.02. The certificates evidencing the OEI Common Stock delivered to
        each Stockholder pursuant to Section 2.05 will bear a legend
        substantially in the form set forth below and containing such other
        information as OEI may deem necessary or appropriate:

               EXCEPT PURSUANT TO THE TERMS OF THE AGREEMENT AND PLAN OF
               REORGANIZATION AMONG THE ISSUER, THE HOLDER OF THIS CERTIFICATE
               AND THE OTHER PARTIES THERETO, THE SHARES REPRESENTED BY THIS
               CERTIFICATE MAY NOT BE VOLUNTARILY SOLD, ASSIGNED, EXCHANGED,
               TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR
               OTHERWISE DISPOSED OF, AND THE ISSUER SHALL NOT BE REQUIRED TO
               GIVE EFFECT TO ANY ATTEMPTED VOLUNTARY SALE, ASSIGNMENT,
               EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION,
               APPOINTMENT OR OTHER DISPOSITION OF ANY OF THOSE SHARES, DURING
               THE TWO-YEAR PERIOD ENDING ON [DATE THAT IS THE SECOND
               ANNIVERSARY OF THE IPO CLOSING DATE] (THE "RESTRICTED PERIOD").
               ON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE
               ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP
               ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE EXPIRATION OF THE
               RESTRICTED PERIOD.

               (b) Each Stockholder, severally and not jointly with any other
        Person, (i) acknowledges that the shares of OEI Common Stock to be
        delivered to him pursuant to Section 2.04 (A) have not been and, except
        pursuant to the Registration Rights Agreement, if applicable, will not
        be registered under the Securities Act and therefore may not be resold
        by him without compliance with the Securities Act and (B) will, as a
        result of their restrictions on transferability which are imposed by
        this Agreement during the Restricted Period, have a value materially
        less at the Effective Time than the value of then freely tradeable
        shares of OEI Common Stock, and (ii) covenants that none of the shares
        of OEI Common Stock issued to him pursuant to Section 2.04 will be
        offered, sold, assigned, pledged, hypothecated, transferred or otherwise
        disposed of except after full compliance with


                                              13
<PAGE>
        all the applicable provisions of the Securities Act and the rules and
        regulations of the SEC and applicable state securities laws and
        regulations. All certificates evidencing shares of OEI Common Stock
        issued pursuant to Section 2.04 will bear the following legend in
        addition to the legend prescribed by Section 11.02(a):

               THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
               SECURITIES ACT OF 1933, AS AMENDED, AND MAY ONLY BE SOLD OR
               OTHERWISE TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THAT ACT
               AND OTHER APPLICABLE SECURITIES LAWS.

        In addition, certificates evidencing shares of OEI Common Stock issued
        to each Stockholder pursuant to Section 2.04 will bear any legend
        required by (i) the securities or blue sky laws of the state in which
        that Stockholder resides or (ii) the Underwriter in connection with any
        agreement of that Stockholder with the Underwriter to the effect set
        forth in Section 11.02(a).

        Section 11.03. BROKERS AND AGENTS. The Stockholders jointly and
severally represent and warrant to OEI that the Company has not directly or
indirectly employed or become obligated to pay any broker or similar agent in
connection with the transactions contemplated hereby and agree, without regard
to the Threshold Amount limitations set forth in Article IX, to indemnify OEI
against all Damage Claims arising out of claims for any and all fees and
commissions of brokers or similar agents employed or promised payment by the
Company.

        Section 11.04. ASSIGNMENT; NO THIRD PARTY BENEFICIARIES. This Agreement
and the rights of its Parties may not be assigned (except by operation of law)
and shall be binding on and inure to the benefit of the Parties, the successors
of OEI, and the heirs and legal representatives of the Stockholders (and, in the
case of any trust, the successor trustees of the trust). Neither this Agreement
nor any other Transaction Document is intended, or shall be construed, deemed or
interpreted, to confer on any Person not a party hereto or thereto any rights or
remedies hereunder or thereunder, except as provided in Section 6.05(b) or
11.14, in Article IX, or as otherwise provided expressly herein or therein.

        Section 11.05. ENTIRE AGREEMENT; AMENDMENT; WAIVERS. This Agreement and
the documents delivered pursuant to it constitute the entire agreement and
understanding among the Parties and supersede all prior agreements and
understandings, both written and oral, relating to the subject matter of this
Agreement. This Agreement may be amended, modified or supplemented, and any
right hereunder may be waived, if, but only if, the amendment, modification,
supplement or waiver is in writing and signed by the Majority Stockholders, the
Company and OEI. The waiver of any of the terms and conditions of this Agreement
shall not be construed or interpreted as, or deemed to be, a waiver of any of
its other term or conditions.

        Section 11.06. COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which will be an original, but all of which together will
constitute one and the same instrument.

Surviving Corporation, will pay all Taxes due upon receipt of the consideration
payable to the Stockholder pursuant to Article II.

        of the Company's bylaws, the Shareholders' Agreement or the Buy-Sell
        Agreement but for the provisions of this Section 11.16; and

        Company shall notify each of the parties to the Stockholders that the
        provisions of this Section 11.16 have terminated.

                                          TERMINATION

        Section 12.01. TERMINATION OF THIS AGREEMENT.

               (a) This Agreement may be terminated at any time prior to the
        Closing solely:

                        (i) by the mutual written consent of OEI and the
                Company;

                       (ii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if the transactions
               contemplated by this Agreement to take place at the Closing shall
               not have been consummated by October 31, 1998, unless the failure
               of such transactions to be consummated results from the willful
               failure of the Party (or in the case of the Stockholders and the
               Company, any of them) seeking to terminate this Agreement to
               perform or adhere to any agreement required hereby to be
               performed or adhered to by that Party prior to or at the Closing
               or thereafter on the IPO Closing Date;

                       (iii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if a material breach or
               default shall be made by the other Party (or in the case of the
               Stockholders and the Company, any of them) in the observance or
               in the due and timely performance of any of the covenants,
               agreements or conditions contained herein; or

                       (iv) by OEI if it is entitled to do so as provided in
               Section 6.07;

               (b) This Agreement may be terminated after the Closing solely:

                       (i) by OEI or the Company if the Underwriting Agreement
               is terminated pursuant to its terms after the Closing and prior
               to the consummation of the IPO; or

                       (ii) automatically and without action on the part of any
               party hereto if the IPO is not consummated within 15 Business
               Days after the date of the Closing.

               (c) If this Agreement is terminated pursuant to this Section
        12.01, the Merger will be deemed for all purposes to have been abandoned
        and of no force or effect. If this Agreement is terminated pursuant to
        this Section 12.01 after the Certificate of Merger has been filed with
        the Secretary of State of the State of Texas, but before the IPO has
        been consummated, OEI will take all actions that Counsel for the Company
        and the Stockholders advises OEI are required by the applicable laws of
        the State of Texas to rescind the Merger.

        Section 12.02. LIABILITIES IN EVENT OF TERMINATION. If this Agreement is
terminated pursuant to Section 12.01, there shall be no liability or obligation
on the part of any Party except (a) as


                                              19
<PAGE>
provided in Section 11.07, (b) to the extent that such liability is based on the
breach of that Party of any of its or his representations, warranties or
covenants set forth in of this Agreement.

        IN WITNESS WHEREOF, the Parties have executed this Agreement as of the
date first above written.

        certificate pursuant to Section 2.04 and the amount of cash payable in
        respect of that certificate pursuant to Section 2.04. All shares of OEI

        have been issued by OEI at the Effective Time. All cash included in the
        Merger Consideration shall be paid by OEI's company checks, certified or
        official bank checks, or wire transfers, at OEI's option. In the case of

        owned by the Stockholder duly endorsed in blank by him, or accompanied
        by stock powers duly executed by him in blank, and with all necessary
        transfer tax and other revenue stamps, acquired at his expense, affixed
        and canceled. In the event this Agreement is terminated pursuant to
        Article XII prior to the Effective Time, OEI or its agent will return
        all such certificates and other documents to the Stockholders. Each
        Stockholder shall cure any deficiencies in the endorsement of the
        certificates or other documents of conveyance respecting, or in the
        stock powers accompanying, the certificates representing Company Common
        Stock delivered by him.

               (c) No dividends (or interest) or other distributions declared or
        earned after the Effective Time with respect to OEI Common Stock and
        payable to the holders of record thereof after the Effective Time will
        be paid to the holder of any unsurrendered certificates representing
        shares of Company Common Stock for which shares of OEI Common Stock have
        been issued in the Merger until the unsurrendered certificates are
        surrendered as provided herein, but (i) on such surrender, OEI will
        cause to be paid, to the Person in whose name the certificates
        representing such shares of OEI Common Stock shall then be issued, the
        amount of dividends or other distributions previously paid with respect
        to such whole shares of OEI Common Stock with a record date, or which
        have accrued, subsequent to the Effective Time, but prior to surrender,
        and the amount of any cash payable to such Person for and in lieu of
        fractional shares pursuant to Section 2.06 and (ii) at the appropriate
        payment date or as soon as practicable thereafter, OEI will cause to be
        paid to that Person the amount of dividends or other distributions with
        a record date, or which have been accrued, subsequent to the Effective
        Time, but which are not payable until a date subsequent to surrender,
        which are payable with respect to such number of whole shares of OEI
        Common Stock, subject in all cases to any applicable escheat laws. No
        interest will be payable with respect to the payment of such dividends
        or other distributions (or cash for and in lieu of fractional shares) on
        surrender of outstanding certificates.

        Section 2.06. FRACTIONAL SHARES. Notwithstanding any other provision of
this Article II, no fractional shares of OEI Common Stock will be issued, and
any Stockholder otherwise entitled to receive a fractional share of OEI Common
Stock but for this Section 2.06 will instead be entitled to receive a cash
payment for and in lieu thereof in the amount (rounded to the nearest whole
cent) equal to that Person's fractional interest in a share of OEI Common Stock
multiplied by $12.

        Section 9.01. INDEMNIFICATION RIGHTS AND OBLIGATIONS. The text of
Article IX of the Uniform Provisions hereby is incorporated herein by this
reference. For purposes of Section 9.07(a), the term "Stockholder Pro Rata
Share" shall be substituted for the term "Pro Rata Share." For purposes of
Section 9.07(b), the Ceiling Amount shall be 91.92% of the amount determined as
the Ceiling Amount for other purposes in this Agreement and the Uniform
Provisions.

                                           ARTICLE X

                                  LIMITATIONS ON COMPETITION

        Section 10.01. PROHIBITED ACTIVITIES. Each Stockholder identified on
Schedule 10.01 (each a "Restricted Stockholder") and, in the case of paragraphs
(b) and (d) below of this Section 10.01, each Stockholder, severally agrees that
he will not during the period beginning on the date hereof and ending on the
third anniversary of the date hereof, directly or indirectly, for any reason,
for his own account or on behalf of or together with any other Person:

               (a) engage as an officer, director or in any other managerial
        capacity or as an owner, co-owner or other investor of or in, whether as
        an employee, independent contractor, consultant or advisor, any business
        engaged in the Practice of Engineering in competition with the Company,
        any Company Subsidiary or OEI or any Subsidiary of OEI (OEI and its
        Subsidiaries collectively being called "OEI" for purposes of this
        Article X) within any territory surrounding any office or facility (each
        a "facility") in which any of the Company or the Company Subsidiaries
        was engaged in business on the date hereof or immediately prior to the
        Effective Time (for purposes of this Article X, the territory
        surrounding a facility shall be: (i) the city, town or village in which
        the facility is located, (ii) the county or parish in which the facility
        is located, (iii) the counties or parishes contiguous to the county or


                                              11
<PAGE>
        parish in which the facility is located, and (iv) the area located
        within 100 miles of the facility, all of such locations being herein
        collectively called the "TERRITORY");

               (b) call on any natural Person who is at that time employed by
        the Company, any Company Subsidiary or OEI with the purpose or intent of
        attracting that person from the employ of the Company, any Company
        Subsidiary or OEI, provided that a Stockholder may call on and hire any
        of his Immediate Family Members;

               (c) call on any Person that at that time is, or at any time
        within one year prior to that time was, a customer of the Company, any
        Company Subsidiary or OEI within the Territory, (i) for the purpose of
        soliciting or selling any product or service in competition with the
        Company, any Company Subsidiary or OEI within the Territory and (ii)
        with the knowledge of the customer relationship; or

               (d) call on any OEI Acquisition Candidate, with the knowledge of
        that Person's status as an OEI Acquisition Candidate, for the purpose of
        acquiring that Person or arranging the acquisition of that Person by any
        Person other than OEI.

Notwithstanding the foregoing, any Restricted Stockholder may own and hold as a
passive investment up to 1% of a class of the outstanding Capital Stock of a
competing Entity if that class of Capital Stock is publicly traded.

        Section 10.02. DAMAGES. Because of the difficulty of measuring economic
losses to OEI as a result of any breach by a Restricted Stockholder or any other
Stockholder of his covenants in Section 10.01, and because of the immediate and
irreparable damage that could be caused to OEI for which it would have no other
adequate remedy, each Restricted Stockholder (and, in the case of paragraphs (b)
and (d) of Section 10.01, each Stockholder) agrees that OEI may enforce the
provisions of Section 10.01 by injunctions and restraining orders against the
Restricted Stockholder or Stockholder, as the case may be, if he breaches any of
those provisions.

        Section 10.03. REASONABLE RESTRAINT. The Parties each agree that
Sections 10.01 and 10.02 impose a reasonable restraint on the Restricted
Stockholder or Stockholders, as the case may be, in light of the activities and
business of OEI on the date hereof, the current business plans of OEI and the
investment by each Stockholder in OEI as a result of the Merger.

        Section 10.04. SEVERABILITY; REFORMATION. The covenants in this Article
X are severable and separate. The unenforceability of any specific covenant in
this Article X is not intended by any Party to, and shall not, affect the
provisions of any other covenant in this Article X. If any court of competent
jurisdiction determines that the scope, time or territorial restrictions set
forth in Section 10.01 are unreasonable as applied to any Restricted Stockholder
or Stockholder, as the case may be, the Parties, including the Restricted
Stockholder or Stockholder in question, acknowledge their mutual intention and
agreement that those restrictions be enforced to the fullest extent the court
deems reasonable, and thereby shall be reformed to that extent as applied to
that Restricted


                                              12
<PAGE>
Stockholder or Stockholder, as the case may be, and any other Restricted
Stockholder or Stockholder, as the case may be, similarly situated.

        Section 10.05. INDEPENDENT COVENANT. All the covenants in this Article X
are intended by each Party to, and shall, be construed as an agreement
independent of any other provision in this Agreement, and the existence of any
claim or cause of action of any Restricted Stockholder or Stockholder against
OEI, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by OEI of any covenant in this Article X. It is
specifically agreed that the period specified in Section 10.01 shall be computed
in the case of each Restricted Stockholder and Stockholder by excluding from
that computation any time during which the Restricted Stockholder or Stockholder
is in violation of any provision of Section 10.01. The covenants contained in
this Article X shall not be affected by any breach of any other provision of
this Agreement by any Party.

        Section 10.06. MATERIALITY. The Company and each Stockholder, severally
and not jointly with any other Person, hereby agree that this Article X is a
material and substantial part of the transactions contemplated by this
Agreement.

                                          ARTICLE XI

                                      GENERAL PROVISIONS

        Section 11.01. TREATMENT OF CONFIDENTIAL INFORMATION. Each Party will
comply with each covenant for which provision is made in Section 11.01 of the
Uniform Provisions (the text of which Section hereby is incorporated herein by
this reference) to be performed or observed by that Party.

        Section 11.02. RESTRICTIONS ON TRANSFERS OF OEI COMMON STOCK.

               (a) During the two-year period ending on the second anniversary
        of the IPO Closing Date (the "RESTRICTED PERIOD"), no Stockholder
        voluntarily will: (i) sell, assign, exchange, transfer, encumber,
        pledge, distribute, appoint or otherwise dispose of (A) any shares of
        OEI Common Stock received by any Stockholder in the Merger or (B) any
        interest in (including any option to buy or sell) any such shares of OEI
        Common Stock, in whole or in part, and OEI will have no obligation to,
        and shall not, treat any such attempted transfer as effective for any
        purpose; or (ii) engage in any transaction, whether or not with respect
        to any shares of OEI Common Stock or any interest therein, the intent or
        effect of which is to reduce the risk of owning the shares of OEI Common
        Stock acquired pursuant to Section 2.04 (including, for example engaging
        in put, call, short-sale, straddle or similar market transactions);
        PROVIDED, HOWEVER, that this Section 11.02 shall not restrict any
        transfer of OEI Common Stock acquired by a Stockholder pursuant to
        Section 2.04 to any of that Stockholder's Related Persons who agree in
        writing to be bound by the provisions of Section 11.01 and this Section
        11.02. The certificates evidencing the OEI Common Stock delivered to
        each Stockholder pursuant to Section 2.05 will bear a legend
        substantially in the form set


                                              13
<PAGE>
        forth below and containing such other information as OEI may deem
        necessary or appropriate:

               EXCEPT PURSUANT TO THE TERMS OF THE AGREEMENT AND PLAN OF
               REORGANIZATION AMONG THE ISSUER, THE HOLDER OF THIS CERTIFICATE
               AND THE OTHER PARTIES THERETO, THE SHARES REPRESENTED BY THIS
               CERTIFICATE MAY NOT BE VOLUNTARILY SOLD, ASSIGNED, EXCHANGED,
               TRANSFERRED, ENCUMBERED, PLEDGED, DISTRIBUTED, APPOINTED OR
               OTHERWISE DISPOSED OF, AND THE ISSUER SHALL NOT BE REQUIRED TO
               GIVE EFFECT TO ANY ATTEMPTED VOLUNTARY SALE, ASSIGNMENT,
               EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION,
               APPOINTMENT OR OTHER DISPOSITION OF ANY OF THOSE SHARES, DURING
               THE TWO-YEAR PERIOD ENDING ON [DATE THAT IS THE SECOND
               ANNIVERSARY OF THE IPO CLOSING DATE] (THE "RESTRICTED PERIOD").
               ON THE WRITTEN REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE
               ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND (AND ANY STOP
               ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE EXPIRATION OF THE
               RESTRICTED PERIOD.

               (b) Each Stockholder, severally and not jointly with any other
        Person, (i) acknowledges that the shares of OEI Common Stock to be
        delivered to him pursuant to Section 2.04 (A) have not been and, except
        pursuant to the Registration Rights Agreement, if applicable, will not
        be registered under the Securities Act and therefore may not be resold
        by him without compliance with the Securities Act and (B) will, as a
        result of their restrictions on transferability which are imposed by
        this Agreement during the Restricted Period, have a value materially
        less at the Effective Time than the value of then freely tradeable
        shares of OEI Common Stock, and (ii) covenants that none of the shares
        of OEI Common Stock issued to him pursuant to Section 2.04 will be
        offered, sold, assigned, pledged, hypothecated, transferred or otherwise
        disposed of except after full compliance with all the applicable
        provisions of the Securities Act and the rules and regulations of the
        SEC and applicable state securities laws and regulations. All
        certificates evidencing shares of OEI Common Stock issued pursuant to
        Section 2.04 will bear the following legend in addition to the legend
        prescribed by Section 11.02(a):

               THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
               SECURITIES ACT OF 1933, AS AMENDED, AND MAY ONLY BE SOLD OR
               OTHERWISE TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THAT ACT
               AND OTHER APPLICABLE SECURITIES LAWS.

        In addition, certificates evidencing shares of OEI Common Stock issued
        to each Stockholder pursuant to Section 2.04 will bear any legend
        required by (i) the securities or blue sky laws of the state in which
        that Stockholder resides or (ii) the Underwriter in connection with any
        agreement of that Stockholder with the Underwriter to the effect set
        forth in Section 11.02(a).

        Section 11.03. BROKERS AND AGENTS. The Stockholders jointly and
severally represent and warrant to OEI that the Company has not directly or
indirectly employed or become obligated to pay


                                              14
<PAGE>
any broker or similar agent in connection with the transactions contemplated
hereby and agree, without regard to the Threshold Amount limitations set forth
in Article IX, to indemnify OEI against all Damage Claims arising out of claims
for any and all fees and commissions of brokers or similar agents employed or
promised payment by the Company.

        Section 11.04. ASSIGNMENT; NO THIRD PARTY BENEFICIARIES. This Agreement
and the rights of its Parties may not be assigned (except by operation of law)
and shall be binding on and inure to the benefit of the Parties, the successors
of OEI, and the heirs and legal representatives of the Stockholders (and, in the
case of any trust, the successor trustees of the trust). Neither this Agreement
nor any other Transaction Document is intended, or shall be construed, deemed or
interpreted, to confer on any Person not a party hereto or thereto any rights or
remedies hereunder or thereunder, except as provided in Section 6.05(b) or
11.14, in Article IX, or as otherwise provided expressly herein or therein.

        Section 11.05. ENTIRE AGREEMENT; AMENDMENT; WAIVERS. This Agreement and
the documents delivered pursuant to it constitute the entire agreement and
understanding among the Parties and supersede all prior agreements and
understandings, both written and oral, relating to the subject matter of this
Agreement. This Agreement may be amended, modified or supplemented, and any
right hereunder may be waived, if, but only if, the amendment, modification,
supplement or waiver is in writing and signed by the Majority Stockholders, the
Company and OEI. The waiver of any of the terms and conditions of this Agreement
shall not be construed or interpreted as, or deemed to be, a waiver of any of
its other term or conditions.

        Section 11.06. COUNTERPARTS. This Agreement may be executed in multiple
counterparts, each of which will be an original, but all of which together will
constitute one and the same instrument.

        Section 11.07. EXPENSES. Whether or not the transactions contemplated
hereby are consummated, (a) OEI will pay the fees, expenses and disbursements of
OEI and Newco and their Representatives which are incurred in connection with
the subject matter of this Agreement and any amendments to this Agreement
including all costs and expenses incurred in the performance of and compliance
with all conditions to be performed by OEI and Newco under this Agreement,
including the costs of preparing the Registration Statement, (b) the Company may
pay any fees, expenses and disbursements of Counsel for the Company and the
Stockholders incurred in connection with the subject matter of this Agreement
and the Registration Statement on or before the IPO Closing Date, up to a
maximum of $40,000 in the aggregate, and (c) the Stockholders will pay from
personal funds, and not from funds of the Company or any Company Subsidiary, (i)
all sales, use, transfer and other similar taxes and fees (collectively,
"TRANSFER TAXES") incurred in connection with the transactions contemplated
hereby, and (ii) the fees, expenses and disbursements in excess of $40,000 in
the aggregate of Counsel for the Company and the Stockholders incurred in
connection with the subject matter of this Agreement and the Registration
Statement on or before the IPO Closing Date. The undertaking of Stockholders to
pay amounts referred to in clause (c) of the preceding sentence shall not
preclude the Stockholders from recovering a portion of such amounts from Other
Stockholders who agree to pay a portion thereof, but failure of any Other
Stockholder to do so will not affect the


                                              15
<PAGE>
obligations of the Stockholders to pay such amounts which, as among OEI, the
Company and the Stockholders, shall be absolute. The Stockholders will file all
necessary documentation and Returns with respect to all Transfer Taxes. In
addition, each Stockholder acknowledges that he, and not the Company, OEI or the
Surviving Corporation, will pay all Taxes due upon receipt of the consideration
payable to the Stockholder pursuant to Article II.

        Section 11.08. NOTICES. All notices required or permitted hereunder
shall be in writing, and shall be deemed to be delivered and received (a) if

Agreement in all respects.

        Section 11.12. REFORMATION AND SEVERABILITY. If any provision of this
Agreement is invalid, illegal or unenforceable, that provision shall, to the
extent possible, be modified in such manner as to be valid, legal and

Stockholders acknowledges and agrees that: (a) no firm commitment, binding
agreement or promise or other assurance of any kind, whether express or implied,
oral or written, exists at the date hereof that the Registration Statement will
become effective or that the IPO will occur at a particular price or within a
particular range of prices or occur at all; (b) neither OEI or any of its
Representatives nor any prospective underwriters in the IPO will have any
liability to the Company, the Stockholders or any of their respective Affiliates
or associates for any failure of (i) the Registration Statement to become
effective (provided, however, that OEI will use its reasonable best efforts to
cause the Registration Statement to become effective prior to October 31, 1998)
or (ii) the IPO to occur at a particular price or within a particular range of
prices or to occur at all; and (c) the decision of Stockholders to enter into
this Agreement, or to vote in favor of or consent to the Merger, has been or
will be made independent of, and without reliance on, any statements, opinions
or other communications of, or due diligence investigations that have been or
will be made or performed by, any prospective underwriter relative to OEI or the
IPO. The Underwriter shall have no obligation to any of the Company and the
Stockholders with respect to any disclosure contained in the Registration
Statement.

        SECTION 11.15. APPOINTMENT OF PROXIES. EACH STOCKHOLDER HEREBY
IRREVOCABLY APPOINTS, CONSTITUTES AND NOMINATES EACH OF MICHAEL L. BURROW AND
GARY J. COURY AND EACH OF THEM ACTING SEPARATELY, THE TRUE AND LAWFUL ATTORNEY
AND PROXY FOR THE STOCKHOLDER, WITH FULL POWER OF SUBSTITUTION, IN THE NAME,
PLACE AND STEAD OF THE STOCKHOLDER, TO VOTE, AT THE SPECIAL MEETING OF
STOCKHOLDERS TO BE HELD PURSUANT TO SECTION 2.07 OF THIS AGREEMENT, AND ANY
ADJOURNMENT OR POSTPONEMENT OF SUCH SPECIAL MEETING, ALL SHARES OF COMPANY
COMMON STOCK WHICH ARE REGISTERED IN THE NAME OF THE STOCKHOLDER ON THE STOCK
TRANSFER RECORDS OF THE COMPANY, IN FAVOR OF THE MERGER AND THE PLAN OF MERGER
DESCRIBED IN THIS AGREEMENT. EACH STOCKHOLDER IS GRANTING THE PROXY AND THE
POWERS AND AUTHORITIES GRANTED IN THIS SECTION 11.15 IN CONSIDERATION OF OEI'S
AND NEWCO'S EXECUTION OF THIS AGREEMENT AND THEIR AGREEMENT TO CONSUMMATE THE
MERGER AND PAY THE MERGER CONSIDERATION, AND IN CONSIDERATION OF EACH OTHER
STOCKHOLDERS' EXECUTION OF THIS AGREEMENT. EACH STOCKHOLDER ACKNOWLEDGES AND
AGREES THAT THE PROXY GRANTED BY THE STOCKHOLDER UNDER THIS SECTION 11.15 IS
IRREVOCABLE AND IS COUPLED WITH AN INTEREST IN THAT (I) OEI AND NEWCO ARE
UNWILLING TO EXECUTE AND DELIVER THIS AGREEMENT UNLESS EACH STOCKHOLDER GRANTS
THE PROXY, (II) THE MERGER IS IN THE BEST INTERESTS OF THE COMPANY AND WILL
BENEFIT BOTH THE COMPANY AND ALL STOCKHOLDERS FROM A FINANCIAL POINT OF VIEW,
AND (III) ALL OF THE OTHER STOCKHOLDERS WISH TO BE ASSURED THAT THE MERGER WILL
BE APPROVED. ALL PREVIOUS PROXIES TO VOTE SHARES OF COMPANY COMMON STOCK OWNED
BY A STOCKHOLDER ARE HEREBY REVOKED BY THAT STOCKHOLDER.

        Section 11.16. BY-LAW AMENDMENT. Prior to the date hereof, the bylaws of

        between the Company and such Stockholder shall be terminated without any
        further action on the part of any party thereto;

               (b) the execution and delivery of this Agreement by the Company
        and the Stockholders shall not be affected by, or constitute a breach of
        or default under, such Stock Subscription Agreement;

               (c) if an Event of Termination (as such term is defined in such
        Stock Subscription Agreement) occurs at any time after the date hereof
        and prior to the Effective Time, the right and obligation of such
        Stockholder to be redeemed, and the right and obligation of the Company
        to redeem such Stockholder, pursuant to such Stock Subscription
        Agreement or pursuant to any other agreement or understanding, shall be
        tolled as of the date of this Agreement, and shall not begin to run,
        unless and until such right and obligation shall be reinstated as
        provided in Section 11.17 (e);

               (d) so long as the rights and obligations of the Company and such
        Stockholder are tolled pursuant to Section 11.17(c), neither party to
        such Stock Subscription Agreement may exercise any right or option such
        party would otherwise have but for the provisions of this Section 11.17;
        and

               (e) if this Agreement is terminated pursuant to Article XII, then
        (i) as of the close of business on the date this Agreement is so
        terminated, the provisions of this Section 11.17 shall terminate and the
        rights and obligations of the Company and such Stockholder with respect
        to the redemption of such Stockholder's shares of Company Common Stock
        shall be reinstated or shall commence, as the case may be, ten days
        following such termination, and (ii) promptly thereafter, the Company
        shall notify each of the Stockholders that the provisions of this
        Section 11.17 have terminated.

        Section 12.01. TERMINATION OF THIS AGREEMENT.

               (a) This Agreement may be terminated at any time prior to the
        Closing solely:

                        (i) by the mutual written consent of OEI and the
                Company;

                       (ii) by the Majority Stockholders or the Company, on the

               contemplated by this Agreement to take place at the Closing shall
               not have been consummated by October 31, 1998, unless the failure
               of such transactions to be consummated results from the willful
               failure of the Party (or in the case of the Stockholders and the
               Company, any of them) seeking to terminate this Agreement to
               perform or adhere to any agreement required hereby to be
               performed or adhered to by that Party prior to or at the Closing
               or thereafter on the IPO Closing Date;

                       (iii) by the Majority Stockholders or the Company, on the
               one hand, or by OEI, on the other hand, if a material breach or
               default shall be made by the other Party (or in the case of the
               Stockholders and the Company, any of them) in the observance or
               in the due and timely performance of any of the covenants,
               agreements or conditions contained herein; or

                       (iv) by OEI if it is entitled to do so as provided in
               Section 6.07;

               (b) This Agreement may be terminated after the Closing solely:

                       (i) by OEI or the Company if the Underwriting Agreement
               is terminated pursuant to its terms after the Closing and prior
               to the consummation of the IPO; or


                                              20

                       (ii) automatically and without action on the part of any
               party hereto if the IPO is not consummated within 15 Business
               Days after the date of the Closing.

               (c) If this Agreement is terminated pursuant to this Section

        and of no force or effect. If this Agreement is terminated pursuant to
        this Section 12.01 after the Certificate of Merger has been filed with

        Company and the Stockholders advises OEI are required by the applicable
        laws of the Commonwealth of Kentucky to rescind the Merger.

terminated pursuant to Section 12.01, there shall be no liability or obligation
on the part of any Party except (a) as provided in Section 11.07, (b) to the
extent that such liability is based on the breach of that Party of any of its or
his representations, warranties or covenants set forth in of this Agreement.

        IN WITNESS WHEREOF, the Parties have executed this Agreement as of the
date first above written.

                                          SECTION 1.

                            PLAN GOVERNANCE, COVERAGE AND BENEFITS

1.1     PURPOSE

        The purpose of the Plan is to foster and promote the long-term financial
success of OEI International, Inc. (the "Company") and its Subsidiaries and to
increase stockholder value by: (a) encouraging the commitment of selected key
Employees, Consultants and Outside Directors, (b) motivating superior
performance of key Employees, Consultants and Outside Directors by means of
long-term performance related incentives, (c) encouraging and providing key
Employees, Consultants and Outside Directors with a program for obtaining
ownership interests in the Company which link and align their personal interests
to those of the Company's stockholders, (d) attracting and retaining key
Employees, Consultants and Outside Directors by providing competitive incentive
compensation opportunities, and (e) enabling key Employees, Consultants and
Outside Directors to share in the long-term growth and success of the Company.

        The Plan provides for payment of various forms of incentive compensation
and it is not intended to be a plan that is subject to the Employee Retirement
Income Security Act of 1974, as amended (ERISA). The Plan shall be interpreted,
construed and administered consistent with its status as a plan that is not
subject to ERISA.

        Subject to approval by the Company's stockholders pursuant to SECTION
7.1, the Plan shall become effective as of April 8, 1998 (the "EFFECTIVE DATE").
The Plan shall commence on the Effective Date, and shall remain in effect,
subject to the right of the Board to amend or terminate the Plan at any time
pursuant to SECTION 7.7, until all Shares subject to the Plan have been
purchased or acquired according to its provisions. However, in no event may an
Incentive Award be granted under the Plan after the expiration of ten (10) years
from the Effective Date. Any Incentive Award granted prior to the Effective Date
shall be subject to the subsequent receipt of stockholder approval of the Plan
pursuant to SECTION 7.1.

        Unexercised and outstanding stock options that were previously granted
by companies that were acquired by, consolidated with, or merged into the
Company may be assumed and continued under this Plan, or such options may be
canceled and substitute options may be granted under this

                                              1

               (g) COMMITTEE. A committee appointed by the Board consisting of
        not less than two directors as appointed by the Board to administer the
        Plan. However, if the Company is a Publicly Held Corporation, the Plan
        shall be administered by a committee appointed by the Board consisting
        of not less than two directors who fulfill the "non-employee director"
        requirements of Rule 16b-3 under the Exchange Act and the "outside
        director" requirements of Section 162(m) of the Code. In either case,
        the Committee may be the Compensation Committee of the Board, or any
        subcommittee of the Compensation Committee, provided that the members of
        the Committee satisfy the requirements of the previous provisions of
        this paragraph. The Board shall have the power to fill vacancies on the
        Committee arising by resignation, death, removal or otherwise. The
        Board, in its sole discretion, may bifurcate the powers and duties of
        the Committee among one or more separate committees, or retain all
        powers and duties of the Committee in a single Committee. The members of
        the Committee shall serve at the discretion of the Board.

               Notwithstanding the preceding paragraph, the term "Committee" as
        used in the Plan with respect to any Incentive Award for an Outside
        Director shall refer to the Board. In the case of an Incentive Award for
        an Outside Director, the Board shall have all the powers and
        responsibilities of the Committee hereunder as to such Incentive Award,
        and any actions as to such Incentive Award may be acted upon only by the
        Board (unless it otherwise designates in its discretion). When the Board
        exercises its authority to act in the capacity as the Committee
        hereunder with respect to an Incentive Award for an Outside Director, it
        shall so designate with respect to any action that it undertakes in its
        capacity as the Committee.

               (h) COMMON STOCK. The common stock of the Company, $.001 par
        value per share, and any class of common stock into which such common
        shares may hereafter be converted, reclassified or recapitalized.

        individual who has agreed to become an Employee, or any other individual
        who is not an Outside Director or employee of the Company (or any Parent
        or Subsidiary) and who, in the opinion of the Committee, is in a
        position to contribute materially to the growth or financial success of
        the Company (or any Parent or Subsidiary).

               (k) COVERED EMPLOYEE. Only if the Company is a Publicly Held
        Corporation, a named executive officer who is one of the group of
        covered employees as defined in Section 162(m) of the Code and Treasury
        Regulation ss. 1.162-27(c) (or its successor).

        forth in the Incentive Agreement pertaining thereto.

               (m) DISABILITY. As determined by the Committee in its discretion
        exercised in good faith, a physical or mental condition of the Employee
        that would entitle him to payment of disability income payments under
        the Company's long term disability insurance policy or plan for
        employees, as then effective, if any; or in the event that the Grantee
        is not covered, for whatever reason, under the Company's long-term
        disability insurance policy or plan, "Disability" means a permanent and
        total disability as defined in Section 22(e)(3) of the Code. A
        determination of Disability may be made by a physician selected or
        approved by the Committee and, in this respect, the Grantee shall submit
        to an examination by such physician upon request.

               (n) EMPLOYEE. Any employee of the Company (or any Parent or
        Subsidiary) within the meaning of Section 3401(c) of the Code who, in
        the opinion of the Committee, is one of a select group of executive
        officers, other officers, or other key personnel of the Company (or any
        Parent or Subsidiary), who is in a position to contribute materially to
        the growth and development and to the financial success of the Company
        (or any Parent or Subsidiary), including, without limitation, officers
        who are members of the Board.

        issuing or assuming such Incentive Award, as the parent-subsidiary
        relationship shall be determined at the time of the corporate action
        described in Section 424(a) of the Code. In this regard, neither the
        transfer of a Grantee from Employment by the Company to Employment by
        any Parent or Subsidiary, nor the transfer of a Grantee from Employment
        by any Parent or Subsidiary to Employment by the Company, shall be
        deemed to be a termination of Employment of the Grantee. Moreover, the
        Employment of a Grantee shall not be deemed to have been terminated
        because of an approved leave of absence from active Employment on
        account of temporary illness, authorized vacation or granted for reasons
        of professional advancement, education, health, or government service,
        or during military leave for any period (if the Grantee returns to
        active Employment within 90 days after the termination of military
        leave), or during any period required to be treated as a leave of
        absence by virtue of any applicable statute, Company personnel policy or
        agreement. Whether an authorized leave of absence shall constitute
        termination of Employment hereunder shall be determined by the Committee
        in its discretion.

                                              4

               Unless otherwise provided in the Incentive Agreement, the term
        "Employment" for purposes of the Plan will also include compensatory

        its discretion exercised in good faith. In this respect, the Committee
        may rely on such financial data, valuations or experts as it deems
        advisable under the circumstances.

               If the Company is a Publicly Held Corporation, the Fair Market
        Value of one share of Common Stock on the date in question is deemed to

        exchange on which Shares are then listed or admitted to trading, or (ii)
        if not so reported, the average of the closing bid and asked prices for

        The Committee's decisions and determinations with respect to any
        Incentive Award need not be uniform and may be made selectively among
        Incentive Awards and Grantees, whether or not such Incentive Awards are
        similar or such Grantees are similarly situated.

               (d) MODIFICATION OF OUTSTANDING INCENTIVE AWARDS. Subject to the
        stockholder approval requirements of SECTION 7.7 if applicable, the
        Committee may, in its discretion, provide for the extension of the
        exercisability of an Incentive Award, accelerate the vesting or
        exercisability of an Incentive Award, eliminate or make less restrictive
        any restrictions contained in an Incentive Award, waive any restriction
        or other provisions of an Incentive Award, or otherwise amend or modify
        an Incentive Award in any manner that is either (i) not adverse to the
        Grantee to whom such Incentive Award was granted or (ii) consented to by
        such Grantee. The Committee may grant an Incentive Award to an
        individual who it expects to become an Employee within the next six
        months, with such Incentive Award being subject to such individual
        actually becoming an Employee within such time period, and subject to
        such other terms and conditions as may be established by the Committee
        in its discretion.

               (e) DELEGATION OF AUTHORITY. The Committee may delegate to the
        Chief Executive Officer and to other senior officers of the Company its
        duties under this Plan pursuant to such conditions or limitations as the
        Committee may establish from time to time, except that, if the Company
        is a Publicly Held Corporation, the Committee may not delegate to any
        person the authority to (i) grant Incentive Awards, or (ii) take any
        action which would contravene the requirements of Rule 16b-3 under the
        Exchange Act or the Performance-Based Exception under Section 162(m) of
        the Code.

               (f) EXPENSES OF COMMITTEE. The Committee may employ legal
        counsel, including, without limitation, independent legal counsel and
        counsel regularly employed by the Company, and other agents as the
        Committee may deem appropriate for the administration of the Plan. The
        Committee may rely upon any opinion or computation received from any
        such counsel or agent. All expenses incurred by the Committee in
        interpreting and administering the Plan, including, without limitation,
        meeting expenses and professional fees, shall be paid by the Company.

               (g) SURRENDER OF PREVIOUS INCENTIVE AWARDS. The Committee may, in
        its absolute discretion, grant Incentive Awards to Grantees on the
        condition that such Grantees surrender to the Committee for cancellation
        such other Incentive Awards (including, without limitation, Incentive
        Awards with higher exercise prices) as the Committee directs. Incentive
        Awards granted on the condition precedent of surrender of outstanding
        Incentive Awards

                                              9
<PAGE>
        shall not count against the limits set forth in SECTION 1.4 until such
        time as such previous Incentive Awards are surrendered and cancelled.

               (h) INDEMNIFICATION. Each person who is or was a member of the
        Committee, or of the Board, shall be indemnified by the Company against
        and from any damage, loss, liability, cost and expense that may be
        imposed upon or reasonably incurred by him in connection with or
        resulting from any claim, action, suit, or proceeding to which he may be
        a party or in which he may be involved by reason of any action taken or
        failure to act under the Plan, except for any such act or omission
        constituting willful misconduct or gross negligence. Such person shall
        be indemnified by the Company for all amounts paid by him in settlement
        thereof, with the Company's approval, or paid by him in satisfaction of
        any judgment in any such action, suit, or proceeding against him,
        provided he shall give the Company an opportunity, at its own expense,
        to handle and defend the same before he undertakes to handle and defend
        it on his own behalf. The foregoing right of indemnification shall not
        be exclusive of any other rights of indemnification to which such
        persons may be entitled under the Company's Articles of Incorporation or
        Bylaws, as a matter of law, or otherwise, or any power that the Company
        may have to indemnify them or hold them harmless.

1.4     SHARES OF COMMON STOCK AVAILABLE FOR INCENTIVE AWARDS

        Subject to adjustment under SECTION 6.5, there shall be available for
Incentive Awards under the Plan granted wholly or partly in Common Stock
(including rights or Options that may be exercised for or settled in Common
Stock) an aggregate of the greater of (a) Two Million (2,000,000) Shares of
Common Stock or (b) ten percent (10%) of the number of Shares issued and
outstanding on the last day of each fiscal quarter of the Company. No more than
1,000,000 Shares shall be available for Incentive Awards granted to Outside
Directors. No more than 2,000,000 Shares of Common Stock shall be available for
Incentive Awards of Incentive Stock Options.

        The number of Shares of Common Stock that are the subject of Incentive
Awards under the Plan, which are forfeited or terminated, expire unexercised,
are settled in cash in lieu of Common Stock or in a manner such that all or some
of the Shares covered by an Incentive Award are not issued to a Grantee or are
exchanged for Incentive Awards that do not involve Common Stock, shall again
immediately become available for Incentive Awards hereunder. The Committee may
from time to time adopt and observe such procedures concerning the counting of
Shares against the Plan maximum as it may deem appropriate. The Board and the
appropriate officers of the Company shall from time to time take whatever
actions are necessary to file any required documents with governmental
authorities, stock exchanges and transaction reporting systems to ensure that
Shares are available for issuance pursuant to Incentive Awards.


                                              10
<PAGE>
        If the Company is a Publicly Held Corporation, then unless and until the
Committee determines that a particular Incentive Award granted to a Covered
Employee is not intended to comply with the Performance-Based Exception, the
following rules shall apply to grants of Incentive Awards to Covered Employees:

               (a) Subject to adjustment as provided in SECTION 6.5, the maximum
        aggregate number of Shares of Common Stock (including Stock Options,
        SARs, Restricted Stock, Performance Units and Performance Shares paid
        out in Shares, or Other Stock-Based Awards paid out in Shares) that may
        be granted or that may vest, as applicable, in any calendar year
        pursuant to any Incentive Award held by any individual Covered Employee
        shall be one million (1,000,000) Shares.

               (b) The maximum aggregate cash payout (including SARs,
        Performance Units and Performance Shares paid out in cash, or Other
        Stock-Based Awards paid out in cash) with respect to Incentive Awards
        granted in any calendar year which may be made to any Covered Employee
        shall be Five Million Dollars ($5,000,000).

               (c) With respect to any Stock Option or Stock Appreciation Right
        granted to a Covered Employee that is canceled or repriced, the number
        of Shares subject to such Stock Option or Stock Appreciation Right shall
        continue to count against the maximum number of Shares that may be the
        subject of Stock Options or Stock Appreciation Rights granted to such
        Covered Employee hereunder and, in this regard, such maximum number
        shall be determined in accordance with Section 162(m) of the Code.

               (d) The limitations of subsections (a), (b) and (c) above shall
        be construed and administered so as to comply with the Performance-Based
        Exception.

1.5     SHARE POOL ADJUSTMENTS FOR AWARDS AND PAYOUTS.

        The following Incentive Awards and payouts shall reduce, on a one Share
for one Share basis, the number of Shares authorized for issuance under the
Share Pool:

               (a)    Stock Option;

               (b)    SAR (except a Tandem SAR);

               (c)    Restricted Stock;

               (d)    A payout of a Performance Share in Shares;

               (e)    A payout of a Performance Unit in Shares; and

                                              11
<PAGE>
               (f) A payout of an Other Stock-Based Award in Shares.

        The following transactions shall restore, on a one Share for one Share
basis, the number of Shares authorized for issuance under the Share Pool:

               (a) A Payout of an SAR, Tandem SAR, Restricted Stock Award, or
        Other Stock-Based Award in the form of cash;

               (b) A cancellation, termination, expiration, forfeiture, or lapse
        for any reason (with the exception of the termination of a Tandem SAR
        upon exercise of the related Stock Option, or the termination of a
        related Stock Option upon exercise of the corresponding Tandem SAR) of
        any Shares subject to an Incentive Award; and

               (c) Payment of an Option Price with previously acquired Shares or
        by withholding Shares which otherwise would be acquired on exercise
        (i.e., the Share Pool shall be increased by the number of Shares turned
        in or withheld as payment of the Option Price).

1.6     COMMON STOCK AVAILABLE.

        The Common Stock available for issuance or transfer under the Plan shall
be made available from Shares now or hereafter (i) held in the treasury of the
Company, (ii) authorized but unissued shares, or (iii) shares to be purchased or
acquired by the Company. No fractional shares shall be issued under the Plan;
payment for fractional shares shall be made in cash.

1.7     PARTICIPATION

               (a) ELIGIBILITY. The Committee shall from time to time designate
        those Employees, Consultants and/or Outside Directors, if any, to be
        granted Incentive Awards under the Plan, the type of Incentive Awards
        granted, the number of Shares, Stock Options, rights or units, as the
        case may be, which shall be granted to each such person, and any other
        terms or conditions relating to the Incentive Awards as it may deem
        appropriate to the extent consistent with the provisions of the Plan. A
        Grantee who has been granted an Incentive Award may, if otherwise
        eligible, be granted additional Incentive Awards at any time.

               (b) INCENTIVE STOCK OPTION ELIGIBILITY. No Consultant or Outside
        Director shall be eligible for the grant of any Incentive Stock Option.
        In addition, no Employee shall be eligible for the grant of any
        Incentive Stock Option who owns or would own immediately before the
        grant of such Incentive Stock Option, directly or indirectly, stock
        possessing more than ten percent (10%) of the total combined voting
        power of all classes of stock of the Company, or any Parent or
        Subsidiary. This restriction does not apply if, at the time such

                                              12
<PAGE>
        Incentive Stock Option is granted, the Incentive Stock Option exercise
        price is at least one hundred and ten percent (110%) of the Fair Market
        Value on the date of grant and the Incentive Stock Option by its terms
        is not exercisable after the expiration of five (5) years from the date
        of grant. For the purpose of the immediately preceding sentence, the
        attribution rules of Section 424(d) of the Code shall apply for the
        purpose of determining an Employee's percentage ownership in the Company
        or any Parent or Subsidiary. This paragraph shall be construed
        consistent with the requirements of Section 422 of the Code.

1.8     TYPES OF INCENTIVE AWARDS

        The types of Incentive Awards under the Plan are Stock Options, Stock
Appreciation Rights and Supplemental Payments as described in SECTION 2,
Restricted Stock and Supplemental Payments as described in SECTION 3,
Performance Units, Performance Shares and Supplemental Payments as described in
SECTION 4, Other Stock-Based Awards and Supplemental Payments as described in
SECTION 5, or any combination of the foregoing.

                                          SECTION 2.

                          STOCK OPTIONS AND STOCK APPRECIATION RIGHTS

2.1     GRANT OF STOCK OPTIONS

        The Committee is authorized to grant (a) Nonstatutory Stock Options to
Employees, Consultants and/or Outside Directors and (b) Incentive Stock Options
to Employees only, in accordance with the terms and conditions of the Plan, and
with such additional terms and conditions, not inconsistent with the Plan, as
the Committee shall determine in its discretion. Successive grants may be made
to the same Grantee whether or not any Stock Option previously granted to such
person remains unexercised.

2.2     STOCK OPTION TERMS

               (a) WRITTEN AGREEMENT. Each grant of an Stock Option shall be
        evidenced by a written Incentive Agreement. Among its other provisions,
        each Incentive Agreement shall set forth the extent to which the Grantee
        shall have the right to exercise the Stock Option following termination
        of the Grantee's Employment. Such provisions shall be determined in the
        discretion of the Committee, shall be included in the Grantee's
        Incentive Agreement, need not be uniform among all Stock Options issued
        pursuant to the Plan.

                                              13
<PAGE>
               (b) NUMBER OF SHARES. Each Stock Option shall specify the number
        of Shares of Common Stock to which it pertains.

               (c) EXERCISE PRICE. The exercise price per Share of Common Stock
        under each Stock Option shall be determined by the Committee; provided,
        however, that in the case of an Incentive Stock Option, such exercise
        price shall not be less than 100% of the Fair Market Value per Share on
        the date the Incentive Stock Option is granted. To the extent that the
        Company is a Publicly Held Corporation and the Stock Option is intended
        to qualify for the Performance-Based Exception, the exercise price shall
        not be less than 100% of the Fair Market Value per Share on the date the
        Stock Option is granted. Each Stock Option shall specify the method of
        exercise which shall be consistent with the requirements of SECTION
        2.3(A).

               (d) TERM. In the Incentive Agreement, the Committee shall fix the
        term of each Stock Option which shall be not more than ten (10) years
        from the date of grant. In the event no term is fixed, such term shall
        be ten (10) years from the date of grant.

               (e) EXERCISE. The Committee shall determine the time or times at
        which a Stock Option may be exercised in whole or in part. Each Stock
        Option may specify the required period of continuous Employment and/or
        the performance objectives to be achieved before the Stock Option or
        portion thereof will become exercisable. Each Stock Option, the exercise
        of which, or the timing of the exercise of which, is dependent, in whole
        or in part, on the achievement of designated performance objectives, may
        specify a minimum level of achievement in respect of the specified
        performance objectives below which no Stock Options will be exercisable
        and a method for determining the number of Stock Options that will be
        exercisable if performance is at or above such minimum but short of full
        achievement of the performance objectives. All such terms and conditions
        shall be set forth in the Incentive Agreement.

               (f) $100,000 ANNUAL LIMIT ON INCENTIVE STOCK OPTIONS.
        Notwithstanding any contrary provision in the Plan, to the extent that
        the aggregate Fair Market Value (determined as of the time the Incentive
        Stock Option is granted) of the Shares of Common Stock with respect to
        which Incentive Stock Options are exercisable for the first time by any
        Grantee during any single calendar year (under the Plan and any other
        stock option plans of the Company and its Subsidiaries or Parent)
        exceeds the sum of $100,000, such Incentive Stock Option shall be
        treated as a Nonstatutory Stock Option to the extent in excess of the
        $100,000 limit, and not an Incentive Stock Option, but all other terms
        and provisions of such Stock Option shall remain unchanged. This
        paragraph shall be applied by taking Incentive Stock Options into
        account in the order in which they are granted and shall be construed in
        accordance with Section 422(d) of the Code. In the absence of such
        regulations or other

                                              14
<PAGE>
        authority, or if such regulations or other authority require or permit a
        designation of the Options which shall cease to constitute Incentive
        Stock Options, then Incentive Stock Options, only to the extent of such
        excess and in the order in which they were granted, shall automatically
        be deemed to be Nonstatutory Stock Options but all other terms and
        conditions of such Incentive Stock Options, and the corresponding
        Incentive Agreement, shall remain unchanged.

2.3     STOCK OPTION EXERCISES

               (a) METHOD OF EXERCISE AND PAYMENT. Stock Options shall be
        exercised by the delivery of a signed written notice of exercise to the
        Company as of a date set by the Company in advance of the effective date
        of the proposed exercise. The notice shall set forth the number of
        Shares with respect to which the Option is to be exercised, accompanied
        by full payment for the Shares.

               The Option Price upon exercise of any Stock Option shall be
        payable to the Company in full either: (i) in cash or its equivalent, or
        (ii) subject to prior approval by the Committee in its discretion, by
        tendering previously acquired Shares having an aggregate Fair Market
        Value at the time of exercise equal to the total Option Price (provided
        that the Shares which are tendered must have been held for at least six
        (6) months prior to their tender to satisfy the Option Price), or (iii)
        subject to prior approval by the Committee in its discretion, by
        withholding Shares which otherwise would be acquired on exercise having
        an aggregate Fair Market Value at the time of exercise equal to the
        total Option Price, or (iv) subject to prior approval by the Committee
        in its discretion, by a combination of (i), (ii), and (iii) above. Any
        payment in Shares of Common Stock shall be effected by the delivery of
        such Shares to the Secretary of the Company, duly endorsed in blank or
        accompanied by stock powers duly executed in blank, together with any
        other documents as the Secretary shall require from time to time.

               The Committee, in its discretion, also may allow (i) "cashless
        exercise" as permitted under Federal Reserve Board's Regulation T, 12
        CFR Part 220 (or its successor), and subject to applicable securities
        law restrictions and tax withholdings, or (ii) by any other means which
        the Committee, in its discretion, determines to be consistent with the
        Plan's purpose and applicable law.

               As soon as practicable after receipt of a written notification of
        exercise and full payment, the Company shall deliver to or on behalf of
        the Grantee, in the name of the Grantee or other appropriate recipient,
        Share certificates for the number of Shares purchased under the Stock
        Option. Such delivery shall be effected for all purposes when a stock

                                              15
<PAGE>
        transfer agent of the Company shall have deposited such certificates in
        the United States mail, addressed to Grantee or other appropriate
        recipient.

               During the lifetime of a Grantee, each Option granted to him
        shall be exercisable only by the Grantee (or his legal guardian in the
        event of his Disability) or by a broker-dealer acting on his behalf
        pursuant to a cashless exercise under the foregoing provisions of this
        SECTION 2.3(A). No Option shall be assignable or transferable by Grantee
        otherwise than by will or by the laws of descent and distribution.

               (b) RESTRICTIONS ON SHARE TRANSFERABILITY. The Committee may
        impose such restrictions on any Shares acquired pursuant to the exercise
        of a Stock Option as it may deem advisable, including, without
        limitation, restrictions under (i) any buy/sell agreement or right of
        first refusal, (ii) any applicable federal securities laws, (iii) the
        requirements of any stock exchange or market upon which such Shares are
        then listed and/or traded, or (iv) any blue sky or state securities law
        applicable to such Shares. Any certificate issued to evidence Shares
        issued upon the exercise of an Incentive Award may bear such legends and
        statements as the Committee shall deem advisable to assure compliance
        with federal and state laws and regulations.

               Any Grantee or other person exercising an Incentive Award may be
        required by the Committee to give a written representation that the
        Incentive Award and the Shares subject to the Incentive Award will be
        acquired for investment and not with a view to public distribution;
        provided, however, that the Committee, in its sole discretion, may
        release any person receiving an Incentive Award from any such
        representations either prior to or subsequent to the exercise of the
        Incentive Award.

               (c) NOTIFICATION OF DISQUALIFYING DISPOSITION OF SHARES FROM
        INCENTIVE STOCK OPTIONS. Notwithstanding any other provision of the
        Plan, a Grantee who disposes of Shares of Common Stock acquired upon the
        exercise of an Incentive Stock Option by a sale or exchange either (i)
        within two (2) years after the date of the grant of the Incentive Stock
        Option under which the Shares were acquired or (ii) within one (1) year
        after the transfer of such Shares to him pursuant to exercise, shall
        promptly notify the Company of such disposition, the amount realized and
        his adjusted basis in such Shares.

               (d) PROCEEDS OF OPTION EXERCISE. The proceeds received by the
        Company from the sale of Shares pursuant to Stock Options exercised
        under the Plan shall be used for general corporate purposes.

                                              16

2.4     STOCK APPRECIATION RIGHTS IN TANDEM WITH NONSTATUTORY STOCK OPTIONS

               (a) GRANT. The Committee may, at the time of grant of a
        Nonstatutory Stock Option, or at any time thereafter during the term of
        the Nonstatutory Stock Option, grant Stock Appreciation Rights with
        respect to all or any portion of the Shares of Common Stock covered by
        such Nonstatutory Stock Option. A Stock Appreciation Right in tandem
        with a Nonstatutory Stock Option is referred to herein as a "TANDEM
        SAR."

               (b) GENERAL PROVISIONS. The terms and conditions of each Tandem
        SAR shall be evidenced by an Incentive Agreement. The Option Price per
        Share of a Tandem SAR shall be fixed in the Incentive Agreement and
        shall not be less than one hundred percent (100%) of the Fair Market
        Value of a Share on the grant date of the Nonstatutory Stock Option to
        which it relates.

               (c) EXERCISE. A Tandem SAR may be exercised at any time the
        Nonstatutory Stock Option to which it relates is then exercisable, but
        only to the extent such Nonstatutory Stock Option is exercisable, and
        shall otherwise be subject to the conditions applicable to such
        Nonstatutory Stock Option. When a Tandem SAR is exercised, the
        Nonstatutory Stock Option to which it relates shall terminate to the
        extent of the number of Shares with respect to which the Tandem SAR is
        exercised. Similarly, when a Nonstatutory Stock Option is exercised, the
        Tandem SARs relating to the Shares covered by such Nonstatutory Stock
        Option exercise shall terminate. Any Tandem SAR which is outstanding on
        the last day of the term of the related Nonstatutory Stock Option shall
        be automatically exercised on such date for cash, without the need for
        any action by the Grantee, to the extent of any Appreciation.

               (d) SETTLEMENT. Upon exercise of a Tandem SAR, the holder shall
        receive, for each Share with respect to which the Tandem SAR is
        exercised, an amount equal to the Appreciation. The Appreciation shall
        be payable in cash, Common Stock, or a combination of both, as specified
        in the Incentive Agreement (or in the discretion of the Committee if not
        so specified). The Appreciation shall be paid within 30 calendar days of
        the exercise of the Tandem SAR. The number of Shares of Common Stock
        which shall be issuable upon exercise of a Tandem SAR shall be
        determined by dividing (1) by (2), where (1) is the number of Shares as
        to which the Tandem SAR is exercised multiplied by the Appreciation in
        such shares and (2) is the Fair Market Value of a Share on the exercise
        date.

2.5     STOCK APPRECIATION RIGHTS INDEPENDENT OF NONSTATUTORY STOCK OPTIONS

               (a) GRANT. The Committee may grant Stock Appreciation Rights
        independent of Nonstatutory Stock Options ("INDEPENDENT SARS").

                                              17
<PAGE>
               (b) GENERAL PROVISIONS. The terms and conditions of each
        Independent SAR shall be evidenced by an Incentive Agreement. The
        exercise price per share of Common Stock shall be not less than one
        hundred percent (100%) of the Fair Market Value of a Share of Common
        Stock on the date of grant of the Independent SAR. The term of an
        Independent SAR shall be determined by the Committee.

               (c) EXERCISE. Independent SARs shall be exercisable at such time
        and subject to such terms and conditions as the Committee shall specify
        in the Incentive Agreement for the Independent SAR grant.

               (d) SETTLEMENT. Upon exercise of an Independent SAR, the holder
        shall receive, for each Share specified in the Independent SAR grant, an
        amount equal to the Spread. The Spread shall be payable in cash, Common
        Stock, or a combination of both, in the discretion of the Committee or
        as specified in the Incentive Agreement. The Spread shall be paid within
        30 calendar days of the exercise of the Independent SAR. The number of
        Shares of Common Stock which shall be issuable upon exercise of an
        Independent SAR shall be determined by dividing (1) by (2), where (1) is
        the number of Shares as to which the Independent SAR is exercised
        multiplied by the Spread in such Shares and (2) is the Fair Market Value
        of a Share on the exercise date.

2.6     RELOAD OPTIONS

        At the discretion of the Committee, the Grantee may be granted under an
Incentive Agreement, replacement Stock Options that permit the Grantee to
purchase an additional number of Shares equal to the number of previously owned
Shares surrendered by the Grantee to pay all or a portion of the Option Price
upon exercise of his Stock Options.

2.7     SUPPLEMENTAL PAYMENT ON EXERCISE OF NONSTATUTORY STOCK OPTIONS OR STOCK
        APPRECIATION RIGHTS

        The Committee, either at the time of grant or as of the time of exercise
of any Nonstatutory Stock Option or Stock Appreciation Right, may provide in the
Incentive Agreement for a Supplemental Payment by the Company to the Grantee
with respect to the exercise of any Nonstatutory Stock Option or Stock
Appreciation Right. The Supplemental Payment shall be in the amount specified by
the Committee, which amount shall not exceed the amount necessary to pay the
federal and state income tax payable with respect to both the exercise of the
Nonstatutory Stock Option and/or Stock Appreciation Right and the receipt of the
Supplemental Payment, assuming the holder is taxed at either the maximum
effective income tax rate applicable thereto or at a lower tax rate as deemed
appropriate by the Committee. The Committee shall have the discretion to grant
Supplemental Payments that are payable solely in cash or Supplemental Payments
that are payable

                                              18
<PAGE>
in cash, Common Stock, or a combination of both, as determined by the Committee
at the time of payment.

                                          SECTION 3.

                                       RESTRICTED STOCK

3.1     AWARD OF RESTRICTED STOCK

               (a) GRANT. In consideration of the performance of Employment by
        any Grantee who is an Employee, Consultant or Outside Director, Shares
        of Restricted Stock may be awarded under the Plan by the Committee with
        such restrictions during the Restriction Period as the Committee may
        designate in its discretion, any of which restrictions may differ with
        respect to each particular Grantee. Restricted Stock shall be awarded
        for no additional consideration or such additional consideration as the
        Committee may determine, which consideration may be less than, equal to
        or more than the Fair Market Value of the shares of Restricted Stock on
        the grant date. The terms and conditions of each grant of Restricted
        Stock shall be evidenced by an Incentive Agreement.

               (b) IMMEDIATE TRANSFER WITHOUT IMMEDIATE DELIVERY OF RESTRICTED
        STOCK. Unless otherwise specified in the Grantee's Incentive Agreement,
        each Restricted Stock Award shall constitute an immediate transfer of
        the record and beneficial ownership of the Shares of Restricted Stock to
        the Grantee in consideration of the performance of services as an
        Employee, Consultant or Outside Director, as applicable, entitling such
        Grantee to all voting and other ownership rights in such Shares subject
        to any restrictions thereon.

               As specified in the Incentive Agreement, a Restricted Stock Award
        may limit the Grantee's dividend rights during the Restriction Period in
        which the shares of Restricted Stock are subject to a "substantial risk
        of forfeiture" (within the meaning given to such term under Code Section
        83) and restrictions on transfer. In the Incentive Agreement, the
        Committee may apply any restrictions to the dividends that the Committee
        deems appropriate. Without limiting the generality of the preceding
        sentence, if the grant or vesting of Shares of Restricted Stock granted
        to a Covered Employee, if applicable, is designed to comply with the
        requirements of the Performance-Based Exception, the Committee may apply
        any restrictions that it deems appropriate to the payment of dividends
        declared with respect to such Shares of Restricted Stock, such that the
        dividends and/or the Shares of Restricted Stock maintain eligibility for
        the Performance-Based Exception. In the event that any dividend
        constitutes a derivative security or an equity security pursuant to the
        rules under Section 16 of the Exchange Act, if applicable, such dividend
        shall be subject to a vesting

                                              19
<PAGE>
        period equal to the remaining vesting period of the Shares of Restricted
        Stock with respect to which the dividend is paid.

               Shares awarded pursuant to a grant of Restricted Stock may be
        issued in the name of the Grantee and held, together with stock powers
        endorsed by the Grantee in blank, by the Committee or the Secretary of
        the Company (or their delegates) as a depository for safekeeping, as
        determined by the Committee, until such time as the forfeiture
        restrictions and the restrictions on transfer have lapsed. All such
        terms and conditions shall be set forth in the particular Grantee's
        Incentive Agreement. The Company or Committee (or their delegates) shall
        issue to the Grantee a receipt evidencing the certificates held by it
        which are registered in the name of the Grantee.

3.2     RESTRICTIONS

               (a) FORFEITURE OF RESTRICTED STOCK. Restricted Stock awarded to a
        Grantee may be subject to the following restrictions until the
        expiration of the Restriction Period: (i) a restriction that constitutes
        a "substantial risk of forfeiture" (as defined in Code Section 83), or a
        restriction on transferability; (ii) unless otherwise specified by the
        Committee in the Incentive Agreement, the Restricted Stock that is
        subject to restrictions which are not satisfied shall be forfeited and
        all rights of the Grantee to such Shares shall terminate; and (iii) any
        other restrictions that the Committee determines in advance are
        appropriate, including, without limitation, rights of repurchase or
        first refusal in the Company or provisions subjecting the Restricted
        Stock to a continuing substantial risk of forfeiture in the hands of any
        transferee. Any such restrictions shall be set forth in the particular
        Grantee's Incentive Agreement.

               (b) ISSUANCE OF CERTIFICATES. Coincident with or promptly after
        the date of grant with respect to Shares of Restricted Stock, the
        Company shall cause to be issued a stock certificate, registered in the
        name of the Grantee to whom such Shares of Restricted Stock were
        granted, evidencing such Shares; provided, however, that the Company
        shall not cause to be issued such a stock certificate unless it has
        received a stock power duly endorsed in blank by the Grantee with
        respect to such Shares. Each such stock certificate shall bear the
        following legend or any other legend approved by the Company:

               THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK
               REPRESENTED HEREBY ARE SUBJECT TO THE RESTRICTIONS, TERMS AND
               CONDITIONS (INCLUDING FORFEITURE AND RESTRICTIONS AGAINST
               TRANSFER) CONTAINED IN THE OEI INTERNATIONAL, INC. 1998 INCENTIVE
               PLAN AND AN INCENTIVE AGREEMENT ENTERED INTO BETWEEN THE
               REGISTERED OWNER OF SUCH SHARES AND OEI INTERNATIONAL, INC.. A
               COPY OF THE PLAN AND

                                              20
<PAGE>
               INCENTIVE AGREEMENT ARE ON FILE IN THE CORPORATE OFFICES OF OEI
               INTERNATIONAL, INC..

        Such legend shall not be removed from the certificate evidencing such
        Shares of Restricted Stock until such Shares vest pursuant to the terms
        of the Incentive Agreement.

               (c) REMOVAL OF RESTRICTIONS. The Committee, in its discretion,
        shall have the authority to remove any or all of the restrictions on the
        Restricted Stock if it determines that, by reason of a change in
        applicable law or another change in circumstance arising after the grant
        date of the Restricted Stock, such action is appropriate.

3.3     DELIVERY OF SHARES OF COMMON STOCK

        Subject to withholding taxes under SECTION 7.3 and to the terms of the
Incentive Agreement, a stock certificate evidencing the Shares of Restricted
Stock with respect to which the restrictions in the Incentive Agreement have
lapsed or otherwise been satisfied shall be delivered to the Grantee or other
appropriate recipient free of restrictions. Such delivery shall be effected for
all purposes when the Company shall have deposited such certificate in the
United States mail, addressed to the Grantee or other appropriate recipient.

3.4     SUPPLEMENTAL PAYMENT ON VESTING OF RESTRICTED STOCK

        The Committee, either at the time of grant or vesting of Restricted
Stock, may provide for a Supplemental Payment by the Company to the holder in an
amount specified by the Committee, which amount shall not exceed the amount
necessary to pay the federal and state income tax payable with respect to both
the vesting of the Restricted Stock and receipt of the Supplemental Payment,
assuming the Grantee is taxed at either the maximum effective income tax rate
applicable thereto or at a lower tax rate as deemed appropriate by the
Committee. The Committee shall have the discretion to grant Supplemental
Payments that are payable solely in cash or Supplemental Payments that are
payable in cash, Common Stock, or a combination of both, as determined by the
Committee at the time of payment.

                                              21

                                          SECTION 4.

                           PERFORMANCE UNITS AND PERFORMANCE SHARES

4.1     PERFORMANCE BASED AWARDS

               (a) GRANT. The Committee is authorized to grant Performance Units
        and Performance Shares to selected Grantees who are Employees or
        Consultants. Each grant of Performance Units and/or Performance Shares
        shall be evidenced by an Incentive Agreement in such amounts and upon
        such terms as shall be determined by the Committee. The Committee may
        make grants of Performance Units or Performance Shares in such a manner
        that more than one Performance Period is in progress concurrently. For
        each Performance Period, the Committee shall establish the number of
        Performance Units or Performance Shares and their contingent values
        which may vary depending on the degree to which performance criteria
        established by the Committee are met.

               (b) PERFORMANCE CRITERIA. At the beginning of each Performance
        Period, the Committee shall (i) establish for such Performance Period
        specific financial or non-financial performance objectives that the
        Committee believes are relevant to the Company's business objectives;
        (ii) determine the value of a Performance Unit or the number of Shares
        under a Performance Share grant relative to performance objectives; and
        (iii) notify each Grantee in writing of the established performance
        objectives and, if applicable, the minimum, target, and maximum value of
        Performance Units or Performance Shares for such Performance Period.

               (c) MODIFICATION. If the Committee determines, in its discretion
        exercised in good faith, that the established performance measures or
        objectives are no longer suitable to the Company's objectives because of
        a change in the Company's business, operations, corporate structure,
        capital structure, or other conditions the Committee deems to be
        appropriate, the Committee may modify the performance measures and
        objectives to the extent it considers to be necessary. The Committee
        shall determine whether any such modification would cause the
        Performance Unit or Performance Share to fail to qualify for the
        Performance-Based Exception, if applicable.

               (d) PAYMENT. The basis for payment of Performance Units or
        Performance Shares for a given Performance Period shall be the
        achievement of those performance objectives determined by the Committee
        at the beginning of the Performance Period as specified in the Grantee's
        Incentive Agreement. If minimum performance is not achieved for a
        Performance Period, no payment shall be made and all contingent rights
        shall cease. If minimum performance is achieved or exceeded, the value
        of a Performance Unit or

                                              22
<PAGE>
        Performance Share may be based on the degree to which actual performance
        exceeded the preestablished minimum performance standards. The amount of
        payment shall be determined by multiplying the number of Performance
        Units or Performance Shares granted at the beginning of the Performance
        Period times the final Performance Unit or Performance Share value.
        Payments shall be made, in the discretion of the Committee as specified
        in the Incentive Agreement, solely in cash or Common Stock, or a
        combination of cash and Common Stock, following the close of the
        applicable Performance Period.

               (e) SPECIAL RULE FOR COVERED EMPLOYEES. The Committee may
        establish performance goals applicable to Performance Units or
        Performance Shares awarded to Covered Employees in such a manner as
        shall permit payments with respect thereto to qualify for the
        Performance-Based Exception, if applicable. If a Performance Unit or
        Performance Share granted to a Covered Employee is intended to comply
        with the Performance-Based Exception, the Committee in establishing
        performance goals shall be guided by Treasury Regulation ss.
        1.162-27(e)(2) (or its successor).

4.2   SUPPLEMENTAL PAYMENT ON VESTING OF PERFORMANCE UNITS OR PERFORMANCE SHARES

        The Committee, either at the time of grant or at the time of vesting of
Performance Units or Performance Shares, may provide for a Supplemental Payment
by the Company to the Grantee in an amount specified by the Committee, which
amount shall not exceed the amount necessary to pay the federal and state income
tax payable with respect to both the vesting of such Performance Units or
Performance Shares and receipt of the Supplemental Payment, assuming the Grantee
is taxed at either the maximum effective income tax rate applicable thereto or
at a lower tax rate as seemed appropriate by the Committee. The Committee shall
have the discretion to grant Supplemental Payments that are payable in cash,
Common Stock, or a combination of both, as determined by the Committee at the
time of payment.

                                          SECTION 5.

                                   OTHER STOCK-BASED AWARDS

5.1     GRANT OF OTHER STOCK-BASED AWARDS

        Other Stock-Based Awards may be awarded by the Committee to selected
Grantees that are denominated or payable in, valued in whole or in part by
reference to, or otherwise related to, Shares of Common Stock, as deemed by the
Committee to be consistent with the purposes of the Plan and the goals of the
Company. Other types of Stock-Based Awards include, without limitation, Deferred
Stock, purchase rights, Shares of Common Stock awarded which are not subject to
any restrictions

or conditions, convertible or exchangeable debentures, other rights convertible
into Shares, Incentive Awards valued by reference to the value of securities of
or the performance of a specified Subsidiary, division or department, and
settlement in cancellation of rights of any person with a vested interest in any
other plan, fund, program or arrangement that is or was sponsored, maintained or
participated in by the Company or any Parent or Subsidiary. As is the case with
other Incentive Awards, Other Stock-Based Awards may be awarded either alone or
in addition to or in tandem with any other Incentive Awards.

5.2     OTHER STOCK-BASED AWARD TERMS

               (a) WRITTEN AGREEMENT. The terms and conditions of each grant of
        an Other Stock-Based Award shall be evidenced by an Incentive Agreement.

               (b) PURCHASE PRICE. Except to the extent that an Other
        Stock-Based Award is granted in substitution for an outstanding
        Incentive Award or is delivered upon exercise of a Stock Option, the
        amount of consideration required to be received by the Company shall be
        either (i) no consideration other than services actually rendered (in
        the case of authorized and unissued shares) or to be rendered, or (ii)
        in the case of an Other Stock-Based Award in the nature of a purchase
        right, consideration (other than services rendered or to be rendered) at
        least equal to 50% of the Fair Market Value of the Shares covered by
        such grant on the date of grant.

               (c) PERFORMANCE CRITERIA AND OTHER TERMS. In its discretion, the
        Committee may specify such criteria, periods or goals for vesting in
        Other Stock-Based Awards and payment thereof to the Grantee as it shall
        determine; and the extent to which such criteria, periods or goals have
        been met shall be determined by the Committee. All terms and conditions
        of Other Stock-Based Awards shall be determined by the Committee and set
        forth in the Incentive Agreement. The Committee may also provide for a
        Supplemental Payment similar to such payment as described in SECTION
        4.2.

               (d) PAYMENT. Other Stock-Based Awards may be paid in Shares of
        Common Stock or other consideration related to such Shares, in a single
        payment or in installments and on such dates as determined by the
        Committee, all as specified in the Incentive Agreement.

               (e) DIVIDENDS. The Grantee of an Other Stock-Based Award shall be
        entitled to receive, currently or on a deferred basis, dividends or
        dividend equivalents with respect to the number of Shares covered by the
        Other Stock-Based Award, as determined by the Committee and set forth in
        the Incentive Agreement. The Committee may also provide in the Incentive
        Agreement that such amounts (if any) shall be deemed to have been
        reinvested in additional Shares.

                           PROVISIONS RELATING TO PLAN PARTICIPATION

6.1     PLAN CONDITIONS

               (a) INCENTIVE AGREEMENT. Each Grantee to whom an Incentive Award
        is granted shall be required to enter into an Incentive Agreement with
        the Company, in such a form as is provided by the Committee. The
        Incentive Agreement shall contain specific terms as determined by the
        Committee, in its discretion, with respect to the Grantee's particular
        Incentive Award. Such terms need not be uniform among all Grantees or
        any similarly-situated Grantees. The Incentive Agreement may include,
        without limitation, vesting, forfeiture and other provisions particular
        to the particular Grantee's Incentive Award, as well as, for example,
        provisions to the effect that the Grantee (i) shall not disclose any
        confidential information acquired during Employment with the Company,
        (ii) shall abide by all the terms and conditions of the Plan and such
        other terms and conditions as may be imposed by the Committee, (iii)
        shall not interfere with the employment or other service of any
        employee, (iv) shall not compete with the Company or become involved in
        a conflict of interest with the interests of the Company, (v) shall
        forfeit an Incentive Award if terminated for Cause, (vi) shall not be
        permitted to make an election under Section 83(b) of the Code when
        applicable, and (vii) shall be subject to any other agreement between
        the Grantee and the Company regarding Shares that may be acquired under
        an Incentive Award including, without limitation, an agreement
        restricting the transferability of Shares by Grantee. An Incentive
        Agreement shall include such terms and conditions as are determined by
        the Committee, in its discretion, to be appropriate with respect to any
        individual Grantee. The Incentive Agreement shall be signed by the
        Grantee to whom the Incentive Award is made and by an Authorized
        Officer.

               (b) NO RIGHT TO EMPLOYMENT. Nothing in the Plan or any instrument
        executed pursuant to the Plan shall create any Employment rights
        (including without limitation, rights to continued Employment) in any
        Grantee or affect the right of the Company to terminate the Employment
        of any Grantee at any time without regard to the existence of the Plan.

               (c) SECURITIES REQUIREMENTS. The Company shall be under no
        obligation to effect the registration pursuant to the Securities Act of
        1933 of any Shares of Common Stock to be issued hereunder or to effect
        similar compliance under any state laws. Notwithstanding anything herein
        to the contrary, the Company shall not be obligated to cause to be
        issued or delivered any certificates evidencing Shares pursuant to the
        Plan unless and until the Company is advised by its counsel that the
        issuance and delivery of such certificates is in

                                              25
<PAGE>
        compliance with all applicable laws, regulations of governmental
        authorities, and the requirements of any securities exchange on which
        Shares are traded. The Committee may require, as a condition of the
        issuance and delivery of certificates evidencing Shares of Common Stock
        pursuant to the terms hereof, that the recipient of such Shares make
        such covenants, agreements and representations, and that such
        certificates bear such legends, as the Committee, in its discretion,
        deems necessary or desirable.

               If the Shares issuable on exercise of an Incentive Award are not
        registered under the Securities Act of 1933, the Company may imprint on
        the certificate for such Shares the following legend or any other legend
        which counsel for the Company considers necessary or advisable to comply
        with the Securities Act of 1933:

               THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933 OR UNDER THE
               SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD OR TRANSFERRED
               EXCEPT UPON SUCH REGISTRATION OR UPON RECEIPT BY THE CORPORATION
               OF AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION, IN FORM
               AND SUBSTANCE SATISFACTORY TO THE CORPORATION, THAT REGISTRATION
               IS NOT REQUIRED FOR SUCH SALE OR TRANSFER.

6.2     TRANSFERABILITY

               (a) NON-TRANSFERABLE AWARDS AND OPTIONS. No Incentive Award and
        no right under the Plan, contingent or otherwise, will be (i)
        assignable, saleable, or otherwise transferable by a Grantee except by
        will or by the laws of descent and distribution, or (ii) subject to any
        encumbrance, pledge, lien, assignment or charge of any nature.

               No transfer by will or by the laws of descent and distribution
        shall be effective to bind the Company unless the Committee has been
        furnished with a copy of the deceased Grantee's enforceable will or such
        other evidence as the Committee deems necessary to establish the
        validity of the transfer. Any attempted transfer in violation of this
        SECTION 6.2(A) shall be void and ineffective.

               (b) ABILITY TO EXERCISE RIGHTS. Subject to a valid beneficiary
        designation pursuant to SECTION 7.5, only the Grantee (or his legal
        guardian in the event of Grantee's Disability), or in the event of his
        death, his estate, may exercise Stock Options, receive cash payments and
        deliveries of Shares, and otherwise assume any rights of the Grantee
        hereunder.

                                              26

6.3     RIGHTS AS A STOCKHOLDER

               (a) NO STOCKHOLDER RIGHTS. Except as otherwise provided in his
        Incentive Agreement for the grant of Restricted Stock, a Grantee of an
        Incentive Award (or a permitted transferee of such Grantee) shall have
        no rights as a stockholder with respect to any Shares of Common Stock
        until the issuance of a stock certificate for such Shares.

               (b) REPRESENTATION OF OWNERSHIP. In the case of the exercise of
        an Incentive Award by a person or estate acquiring the right to exercise
        such Incentive Award by reason of the death or Disability of a Grantee,
        the Committee may require reasonable evidence as to the ownership of
        such Incentive Award or the authority of such person and may require
        such consents and releases of taxing authorities as the Committee deems
        advisable.

6.4     LISTING AND REGISTRATION OF SHARES OF COMMON STOCK

        The exercise of any Incentive Award granted hereunder shall only be
effective at such time as counsel to the Company shall have determined that the
issuance and delivery of Shares of Common Stock pursuant to such exercise is in
compliance with all applicable laws, regulations of governmental authorities and
the requirements of any securities exchange on which Shares are traded. The
Committee may, in its discretion, defer the effectiveness of any exercise of an
Incentive Award in order to allow the issuance of Shares to be made pursuant to
registration or an exemption from registration or other methods for compliance
available under federal or state securities laws. The Committee shall inform the
Grantee in writing of its decision to defer the effectiveness of the exercise of
an Incentive Award. During the period that the effectiveness of an Incentive
Award has been deferred, the Grantee may, by written notice to the Committee,
withdraw such exercise and obtain the refund of any amount paid with respect
thereto.

6.5     CHANGE IN STOCK AND ADJUSTMENTS

               (a) CHANGES IN LAW OR CIRCUMSTANCES. Subject to SECTION 6.7
        (which only applies in the event of a Change in Control), in the event
        of any change in applicable laws or any change in circumstances which
        results in or would result in any dilution of the rights granted under
        the Plan, or which otherwise warrants equitable adjustment because it
        interferes with the intended operation of the Plan, then, if the
        Committee should determine, in its absolute discretion, that such change
        equitably requires an adjustment in the number or kind of shares of
        stock or other securities or property theretofore subject, or which may
        become subject, to issuance or transfer under the Plan or in the terms
        and conditions of outstanding Incentive Awards, such adjustment shall be
        made in accordance with such determination. Such adjustments may include
        changes with respect to (i) the aggregate number of Shares that may be
        issued under the Plan, (ii) the number of Shares subject to


                                              27
<PAGE>
        Incentive Awards, and (iii) the price per Share for outstanding
        Incentive Awards. Any adjustment under this paragraph of an outstanding
        Incentive Stock Option shall be made only to the extent not constituting
        a "modification" within the meaning of Section 424(h)(3) of the Code
        unless otherwise agreed to by the Grantee in writing. The Committee
        shall give notice to each applicable Grantee of such adjustment which
        shall be effective and binding.

               (b) EXERCISE OF CORPORATE POWERS. The existence of the Plan or
        outstanding Incentive Awards hereunder shall not affect in any way the
        right or power of the Company or its stockholders to make or authorize
        any or all adjustments, recapitalization, reorganization or other
        changes in the Company's capital structure or its business or any merger
        or consolidation of the Company, or any issue of bonds, debentures,
        preferred or prior preference stocks ahead of or affecting the Common
        Stock or the rights thereof, or the dissolution or liquidation of the
        Company, or any sale or transfer of all or any part of its assets or
        business, or any other corporate act or proceeding whether of a similar
        character or otherwise.

               (c) RECAPITALIZATION OF THE COMPANY. Subject to SECTION 6.7, if
        while there are Incentive Awards outstanding, the Company shall effect
        any subdivision or consolidation of Shares of Common Stock or other
        capital readjustment, the payment of a stock dividend, stock split,
        combination of Shares, recapitalization or other increase or reduction
        in the number of Shares outstanding, without receiving compensation
        therefor in money, services or property, then the number of Shares
        available under the Plan and the number of Incentive Awards which may
        thereafter be exercised shall (i) in the event of an increase in the
        number of Shares outstanding, be proportionately increased and the Fair
        Market Value of the Incentive Awards awarded shall be proportionately
        reduced; and (ii) in the event of a reduction in the number of Shares
        outstanding, be proportionately reduced, and the Fair Market Value of
        the Incentive Awards awarded shall be proportionately increased. The
        Committee shall take such action and whatever other action it deems
        appropriate, in its discretion, so that the value of each outstanding
        Incentive Award to the Grantee shall not be adversely affected by a
        corporate event described in this subsection (c).

               (d) REORGANIZATION OF THE COMPANY. Subject to SECTION 6.7, if the
        Company is reorganized, merged or consolidated, or is a party to a plan
        of exchange with another corporation, pursuant to which reorganization,
        merger, consolidation or exchange, stockholders of the Company receive
        any Shares of Common Stock or other securities or property, or if the
        Company should distribute securities of another corporation to its
        stockholders, each Grantee shall be entitled to receive, in lieu of the
        number of unexercised Incentive Awards previously awarded, the number of
        Stock Options, Stock Appreciation Rights, Performance Shares or Units,
        Restricted Stock shares, or Other Stock-Based Awards, with a
        corresponding adjustment to the Fair Market Value of said Incentive
        Awards, to

                                              28
<PAGE>
        which he would have been entitled if, immediately prior to such
        corporate action, such Grantee had been the holder of record of a number
        of Shares equal to the number of the outstanding Incentive Awards
        payable in Shares that were previously awarded to him. For this purpose,
        Shares of Restricted Stock shall be treated the same as unrestricted
        outstanding Shares of Common Stock. In this regard, the Committee shall
        take whatever other action it deems appropriate to preserve the rights
        of Grantees holding outstanding Incentive Awards.

               (e) ISSUE OF COMMON STOCK BY THE COMPANY. Except as hereinabove
        expressly provided in this SECTION 6.5 and subject to SECTION 6.7, the
        issue by the Company of shares of stock of any class, or securities
        convertible into shares of stock of any class, for cash or property, or
        for labor or services, either upon direct sale or upon the exercise of
        rights or warrants to subscribe therefor, or upon any conversion of
        shares or obligations of the Company convertible into such shares or
        other securities, shall not affect, and no adjustment by reason thereof
        shall be made with respect to, the number of, or Fair Market Value of,
        any Incentive Awards then outstanding under previously granted Incentive
        Awards; provided, however, in such event, outstanding Shares of
        Restricted Stock shall be treated the same as outstanding unrestricted
        Shares of Common Stock.

               (f) ACQUISITION OF THE COMPANY. Subject to SECTION 6.7, in the
        case of any sale of assets, merger, consolidation or combination of the
        Company with or into another corporation other than a transaction in
        which the Company is the continuing or surviving corporation and which
        does not result in the outstanding Shares being converted into or
        exchanged for different securities, cash or other property, or any
        combination thereof (an "Acquisition"), in the absolute discretion of
        the Committee, any Grantee who holds an outstanding Incentive Award
        shall have the right (subject to any limitation applicable to the
        Incentive Award) thereafter and during the term of the Incentive Award,
        to receive upon exercise thereof the Acquisition Consideration (as
        defined below) receivable upon the Acquisition by a holder of the number
        of Shares which would have been obtained upon exercise of the Incentive
        Award immediately prior to the Acquisition. The term "Acquisition
        Consideration" shall mean the kind and amount of shares of the surviving
        or new corporation, cash, securities, evidence of indebtedness, other
        property or any combination thereof receivable in respect of one Share
        upon consummation of an Acquisition. The Committee, in its discretion,
        shall have the authority to take whatever action it deems appropriate to
        effectuate the provisions of this subsection (f).

               (g) ASSUMPTION OF OUTSTANDING INCENTIVE AWARDS UNDER THE PLAN.
        Notwithstanding any other provision of the Plan, the Committee, in its
        absolute discretion, may authorize the assumption and continuation under
        the Plan of outstanding and unexercised stock options or other types of
        stock-based incentive awards that were granted under a stock option plan
        (or other type of stock incentive plan or agreement) that is or was
        maintained by

                                              29
<PAGE>
        a corporation or other entity that was merged into, consolidated with,
        or whose stock or assets were acquired by, the Company as the surviving
        corporation. Any such action shall be upon such terms and conditions as
        the Committee, in its discretion, may deem appropriate, including
        provisions to preserve the holder's rights under the previously granted
        and unexercised stock option or other stock-based incentive award, such
        as, for example, retaining an existing exercise price under an
        outstanding stock option. Any such assumption and continuation of any
        such previously granted and unexercised incentive award shall be treated
        as an outstanding Incentive Award under the Plan and shall thus count
        against the number of Shares reserved for issuance pursuant to SECTION
        1.4. With respect to an incentive stock option (as described in Section
        422 of the Code) subject to this subsection (g), no adjustment to such
        option shall be made to the extent constituting a "modification" within
        the meaning of Section 424(h)(3) of the Code unless otherwise agreed to
        by the optionee in writing.

               (h) ASSUMPTION OF INCENTIVE AWARDS BY A SUCCESSOR. In the event
        of a dissolution or liquidation of the Company, a sale of all or
        substantially all of the Company's assets, a merger or consolidation
        involving the Company in which the Company is not the surviving
        corporation, or a merger or consolidation involving the Company in which
        the Company is the surviving corporation but the holders of Shares of
        Common Stock receive securities of another corporation and/or other
        property, including cash, the Committee shall, in its absolute
        discretion, have the right and power to:

                      (i) cancel, effective immediately prior to the occurrence
               of such corporate event, each outstanding Incentive Award
               (whether or not then exercisable), and, in full consideration of
               such cancellation, pay to the Grantee to whom such Incentive
               Award was granted an amount in cash equal to the excess of (A)
               the value, as determined by the Committee, in its discretion, of
               the property (including cash) received by the holder of a Share
               of Common Stock as a result of such event over (B) the exercise
               or purchase price, if any, of such Incentive Award; or

                      (ii) provide for the exchange of each Incentive Award
               outstanding immediately prior to such corporate event (whether or
               not then exercisable) for another award on some or all of the
               property for which such Incentive Award is exchanged and,
               incident thereto, make an equitable adjustment as determined by
               the Committee, in its discretion, in the exercise or purchase
               price, if any, of the Incentive Award, or the number of shares or
               amount of property (including cash) subject to the Incentive
               Award or, if deemed appropriate, provide for a cash payment to
               the Grantee in consideration for the exchange of his Incentive
               Award.

                                              30
<PAGE>
        The Committee, in its discretion, shall have the authority to take
        whatever action it deems appropriate to effectuate the provisions of
        this subsection (h).

6.6     TERMINATION OF EMPLOYMENT, DEATH, DISABILITY AND RETIREMENT

               (a) TERMINATION OF EMPLOYMENT. Unless otherwise expressly
        provided in the Grantee's Incentive Agreement, if the Grantee's
        Employment is terminated for any reason other than due to his death,
        Disability, Retirement or for Cause, any non-vested portion of any Stock
        Option or other outstanding Incentive Award at the time of such
        termination shall automatically expire and terminate and no further
        vesting shall occur. In such event, except as otherwise expressly
        provided in his Incentive Agreement, the Grantee shall be entitled to
        exercise his rights only with respect to the portion of the Incentive
        Award that was vested as of the termination date for a period that shall
        end on the earlier of (i) the expiration date set forth in the Incentive
        Agreement with respect to the vested portion of such Incentive Award or
        (ii) the date that occurs ninety (90) calendar days after his
        termination date.

               (b) TERMINATION OF EMPLOYMENT FOR CAUSE. Unless otherwise
        expressly provided in the Grantee's Incentive Agreement, in the event of
        the termination of a Grantee's Employment for Cause, all vested and
        non-vested Stock Options and other Incentive Awards granted to such
        Grantee shall immediately expire, and shall not be exercisable, as of
        the commencement of business on the date of such termination.

               (c) RETIREMENT. Unless otherwise expressly provided in the
        Grantee's Incentive Agreement, upon the Retirement of any Employee who
        is a Grantee:

                      (i) any non-vested portion of any outstanding Option or
               other Incentive Award shall immediately terminate and no further
               vesting shall occur; and

                      (ii) any vested Option or other Incentive Award shall
               expire on the earlier of (A) the expiration date set forth in the
               Incentive Agreement for such Incentive Award; or (B) the
               expiration of (1) one year after the date of Retirement in the
               case of any Incentive Award other than an Incentive Stock Option,
               or (2) three months after the date of Retirement in the case of
               an Incentive Stock Option.

               (d) DISABILITY OR DEATH. Unless otherwise expressly provided in
        the Grantee's Incentive Agreement, upon termination of Employment as a
        result of the Grantee's Disability or death:

                                              31
<PAGE>
                      (i) any nonvested portion of any outstanding Option or
               other applicable Incentive Award shall immediately terminate upon
               termination of Employment, as applicable, and no further vesting
               shall occur; and

                      (ii) any vested Incentive Award shall expire upon the
               earlier of either (A) the expiration date set forth in the
               Incentive Agreement or (B) the first anniversary of the Grantee's
               termination of Employment, as applicable, as a result of his
               Disability or death.

               In the case of any vested Incentive Stock Option held by an
        Employee following termination of Employment, notwithstanding the
        definition of "Disability" in SECTION 1.2, whether the Employee has
        incurred a "Disability" for purposes of determining the length of the
        Option exercise period following termination of Employment under this
        paragraph (d) shall be determined by reference to Section 22(e)(3) of
        the Code to the extent required by Section 422(c)(6) of the Code. The
        Committee shall determine whether a Disability for purposes of this
        subsection (d) has occurred.

               (e) CONTINUATION. Subject to the conditions and limitations of
        the Plan and applicable law and regulation in the event that a Grantee
        ceases to be an Employee, Outside Director or Consultant, as applicable,
        for whatever reason, the Committee and Grantee may mutually agree with
        respect to any outstanding Option or other Incentive Award then held by
        the Grantee (i) for an acceleration or other adjustment in any vesting
        schedule applicable to the Incentive Award, (ii) for a continuation of
        the exercise period following termination for a longer period than is
        otherwise provided under such Incentive Award, or (iii) to any other
        change in the terms and conditions of the Incentive Award. In the event
        of any such change to an outstanding Inventive Award, a written
        amendment to the Grantee's Incentive Agreement shall be required.

6.7     CHANGE IN CONTROL

        Notwithstanding any contrary provision in the Plan, in the event of a
Change in Control (as defined below), the following actions shall automatically
occur as of the day immediately preceding the Change in Control date unless
otherwise expressly provided in the Grantee's Incentive Agreement:

               (a) all of the Stock Options and Stock Appreciation Rights then
        outstanding shall become 100% vested and immediately and fully
        exercisable;

                                              32
<PAGE>
               (b) all of the restrictions and conditions of any Restricted
        Stock and any Other Stock-Based Awards then outstanding shall be deemed
        satisfied, and the Restriction Period with respect thereto shall be
        deemed to have expired; and

               (c) all of the Performance Shares, Performance Units and any
        Other Stock-Based Awards shall become fully vested, deemed earned in
        full, and promptly paid within thirty (30) days to the affected Grantees
        without regard to payment schedules and notwithstanding that the
        applicable performance cycle, retention cycle or other restrictions and
        conditions have not been completed or satisfied.

        Notwithstanding any other provision of this Plan, unless expressly
provided otherwise in the Grantee's Incentive Agreement, the provisions of this
SECTION 6.7 may not be terminated, amended, or modified to adversely affect any
Incentive Award theretofore granted under the Plan without the prior written
consent of the Grantee with respect to his outstanding Incentive Award subject,
however, to the last paragraph of this SECTION 6.7.

        For all purposes of the Plan, a "CHANGE IN CONTROL" of the Company shall
mean:

               (a) The acquisition by an individual, entity or group (within the
        meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act (a "PERSON")
        of beneficial ownership (within the meaning of Rule 13d-3 promulgated
        under the Exchange Act) of thirty percent (30%) or more of the total
        voting power of all the Company's then outstanding securities entitled
        to vote generally in the election of directors to the Board; provided,
        however, that for purposes of this subsection (a), the following
        acquisitions shall not constitute a Change in Control: (i) any
        acquisition by the Company or its Parent or Subsidiaries, (ii) any
        acquisition by any employee benefit plan (or related trust) sponsored or
        maintained by the Company or its Parent or Subsidiaries, or (iii) any
        acquisition consummated with the prior approval of the Board; or

               (b) During the period of two consecutive calendar years,
        individuals who at the beginning of such period constitute the Board,
        and any new director(s) whose election by the Board or nomination for
        election by the Company's shareholders was approved by a vote of at
        least two-thirds of the directors then still in office, who either were
        directors at the beginning of the two-year period or whose election or
        nomination for election was previously so approved, cease for any reason
        to constitute a majority of the Board; or

               (c) The Company becomes a party to a merger, plan of
        reorganization, consolidation or share exchange in which either (i) the
        Company will not be the surviving corporation or (ii) the Company will
        be the surviving corporation and any outstanding shares of the Company's
        common stock will be converted into shares of any other company (other

                                              33
<PAGE>
        than a reincorporation or the establishment of a holding company
        involving no change of ownership of the Company) or other securities,
        cash or other property (excluding payments made solely for fractional
        shares); or

               (d) The shareholders of the Company approve a merger, plan of
        reorganization, consolidation or share exchange with any other
        corporation, and immediately following such merger, plan of
        reorganization, consolidation or share exchange the holders of the
        voting securities of the Company outstanding immediately prior thereto
        hold securities representing fifty percent (50%) or less of the combined
        voting power of the voting securities of the Company or such surviving
        entity outstanding immediately after such merger, plan of
        reorganization, consolidation or share exchange; PROVIDED, HOWEVER, that
        notwithstanding the foregoing, no Change in Control shall be deemed to
        have occurred if one-half (1/2) or more of the members of the Board of
        the Company or such surviving entity immediately after such merger, plan
        of reorganization, consolidation or share exchange is comprised of
        persons who served as directors of the Company immediately prior to such
        merger, plan of reorganization, consolidation or share exchange or who
        are otherwise designees of the Company; or

               (e) Upon approval by the Company's stockholders of a complete
        liquidation and dissolution of the Company or the sale or other
        disposition of all or substantially all of the assets of the Company
        other than to a Parent or Subsidiary; or

               (f) Any other event that a majority of the Board, in its sole
        discretion, shall determine constitutes a Change in Control.

        Notwithstanding the occurrence of any of the foregoing events of this
SECTION 6.7 which would otherwise result in a Change in Control, the Board may
determine in its complete discretion, if it deems it to be in the best interest
of the Company, that an event or events otherwise constituting a Change in
Control shall not be considered a Change in Control. Such determination shall be
effective only if it is made by the Board prior to the occurrence of an event
that otherwise would be or probably would lead to a Change in Control; or after
such event if made by the Board a majority of which is composed of directors who
were members of the Board immediately prior to the event that otherwise would be
or probably would lead to a Change in Control.

6.8     EXCHANGE OF INCENTIVE AWARDS

        The Committee may, in its discretion, permit any Grantee to surrender
outstanding Incentive Awards in order to exercise or realize his rights under
other Incentive Awards or in exchange for the grant of new Incentive Awards, or
require holders of Incentive Awards to surrender outstanding

                                              34
<PAGE>
Incentive Awards (or comparable rights under other plans or arrangements) as a
condition precedent to the grant of new Incentive Awards.

6.9     FINANCING

        The Company may extend and maintain, or arrange for and guarantee, the
extension and maintenance of financing to any Grantee to purchase Shares
pursuant to exercise of an Incentive Award upon such terms as are approved by
the Committee in its discretion.

                                          SECTION 7.

                                            GENERAL

7.1     EFFECTIVE DATE AND GRANT PERIOD

        This Plan is adopted by the Board effective as of April 8, 1998 (the
"EFFECTIVE DATE"), subject to the approval of the stockholders of the Company by
April 7, 1999. Incentive Awards may be granted under the Plan at any time prior
to receipt of such stockholder approval; provided, however, if the requisite
stockholder approval is not obtained then any Incentive Awards granted hereunder
shall automatically become null and void and of no force or effect. Unless
sooner terminated by the Board, no Incentive Award shall be granted under the
Plan after ten (10) years from the Effective Date.

7.2     FUNDING AND LIABILITY OF COMPANY

        No provision of the Plan shall require the Company, for the purpose of
satisfying any obligations under the Plan, to purchase assets or place any
assets in a trust or other entity to which contributions are made, or otherwise
to segregate any assets. In addition, the Company shall not be required to
maintain separate bank accounts, books, records or other evidence of the
existence of a segregated or separately maintained or administered fund for
purposes of the Plan. Although bookkeeping accounts may be established with
respect to Grantees who are entitled to cash, Common Stock or rights thereto
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 cash, Common Stock or rights thereto. The Plan
shall not be construed as providing for such segregation, nor shall the Company,
the Board or the Committee be deemed to be a trustee of any cash, Common Stock
or rights thereto. Any liability or obligation of the Company to any Grantee
with respect to an Incentive Award shall be based solely upon any contractual
obligations that may be created by this Plan and any Incentive Agreement, and no
such liability or obligation of the Company shall be deemed to be secured by any
pledge or other

                                              35
<PAGE>
encumbrance on any property of the Company. Neither the Company, the Board nor
the Committee shall be required to give any security or bond for the performance
of any obligation that may be created by the Plan.

7.3     WITHHOLDING TAXES

               (a) TAX WITHHOLDING. The Company shall have the power and the
        right to deduct or withhold, or require a Grantee to remit to the
        Company, an amount sufficient to satisfy federal, state, and local
        taxes, domestic or foreign, required by law or regulation to be withheld
        with respect to any taxable event arising as a result of the Plan or an
        Incentive Award hereunder.

               (b) SHARE WITHHOLDING. With respect to tax withholding required
        upon the exercise of Stock Options or SARs, upon the lapse of
        restrictions on Restricted Stock, or upon any other taxable event
        arising as a result of any Incentive Awards, Grantees may elect, subject
        to the approval of the Committee in its discretion, to satisfy the
        withholding requirement, in whole or in part, by having the Company
        withhold Shares having a Fair Market Value on the date the tax is to be
        determined equal to the minimum statutory total tax which could be
        imposed on the transaction. All such elections shall be made in writing,
        signed by the Grantee, and shall be subject to any restrictions or
        limitations that the Committee, in its discretion, deems appropriate.

               (c) INCENTIVE STOCK OPTIONS. With respect to Shares received by a
        Grantee pursuant to the exercise of an Incentive Stock Option, if such
        Grantee disposes of any such Shares within (i) two years from the date
        of grant of such Option or (ii) one year after the transfer of such
        shares to the Grantee, the Company shall have the right to withhold from
        any salary, wages or other compensation payable by the Company to the
        Grantee an amount sufficient to satisfy federal, state and local tax
        withholding requirements attributable to such disqualifying disposition.

               (d) LOANS. The Committee may provide for loans, on either a short
        term or demand basis, from the Company to a Grantee who is an Employee
        or Consultant to permit the payment of taxes required by law.

7.4     NO GUARANTEE OF TAX CONSEQUENCES

        Neither the Company nor the Committee makes any commitment or guarantee
that any federal, state or local tax treatment will apply or be available to any
person participating or eligible to participate hereunder.

                                              36
<PAGE>
7.5     DESIGNATION OF BENEFICIARY BY PARTICIPANT

        Each Grantee may, from time to time, name any beneficiary or
beneficiaries (who may be named contingently or successively) to whom any
benefit under the Plan is to be paid in case of his death before he receives any
or all of such benefit. Each such designation shall revoke all prior
designations by the same Grantee, shall be in a form prescribed by the
Committee, and will be effective only when filed by the Grantee in writing with
the Committee during the Grantee's lifetime.

        A Grantee may, from time to time, revoke or change his beneficiary
designation by filing a new beneficiary designation form with the Committee (or
its delegate). The last valid designation received shall be controlling;
provided, however, that no beneficiary designation, or change or revocation
thereof, shall be effective unless received prior to the Grantee's death and in
no event shall it be effective as of a date prior to its receipt.
Notwithstanding any contrary provision of this SECTION 7.5, no beneficiary
designation made by a married Grantee, other than one under which the surviving
lawful spouse of such Grantee is designated as the sole beneficiary, shall be
valid and effective without the written consent of such spouse.

        As determined by the Committee, if no valid and effective beneficiary
designation exists at the time of the Grantee's death, no designated beneficiary
survives the Grantee, or if such designation conflicts with applicable law, the
payment of the Grantee's Incentive Award, if earned and payable hereunder, shall
be made to the Grantee's surviving lawful spouse, if any, or if there is no such
surviving spouse, to the executor or administrator of his estate. If the
Committee is in doubt as to the right of any person to receive such amount, the
Committee may direct that the amount be paid into any court of competent
jurisdiction in an interpleader or other action, and such payment, to the extent
thereof, shall be a full and complete discharge of any liability or obligation
therefor under the Plan and the Incentive Agreement.

7.6     DEFERRALS

        The Committee may permit a Grantee to defer such Grantee's receipt of
the payment of cash or the delivery of Shares that would, otherwise be due to
such Grantee by virtue of the lapse or waiver of restrictions with respect to
Restricted Stock, or the satisfaction of any requirements or goals with respect
to Performance Units, Performance Shares or Other Stock-Based Awards. If any
such deferral election is permitted, the Committee shall, in its discretion,
establish rules and procedures for such payment deferrals to the extent
consistent with the Code.

                                              37
<PAGE>
7.7     AMENDMENT AND TERMINATION

        The Board shall have complete power and authority to terminate or amend
the Plan at any time; provided, however, that the Board shall not, without the
approval of the stockholders of the Company within the time period required by
applicable law, (a) except as provided in SECTION 6.5, increase the maximum
number of Shares which may be issued under the Plan pursuant to SECTION 1.4, (b)
amend the requirements as to the class of Employees eligible to purchase Common
Stock under the Plan, (c) to the extent applicable, increase the maximum limits
on Incentive Awards to Covered Employees as set for compliance with the
Performance-Based Exception, (d) extend the term of the Plan, or (e) to the
extent applicable, decrease the authority granted to the Committee under the
Plan in contravention of Rule 16b-3 under the Exchange Act.

        No termination, amendment, or modification of the Plan shall adversely
affect in any material way any outstanding Incentive Award previously granted to
a Grantee under the Plan, without the written consent of such Grantee or other
designated holder of such Incentive Award.

        In addition, to the extent that the Committee determines that (a) the
listing for qualification requirements of any national securities exchange or
quotation system on which the Company's Common Stock is then listed or quoted,
if applicable, or (b) the Code (or regulations promulgated thereunder), require
stockholder approval in order to maintain compliance with such listing
requirements or to maintain any favorable tax advantages or qualifications, then
the Plan shall not be amended in such respect without approval of the Company's
stockholders.

7.8     REQUIREMENTS OF LAW

        The granting of Incentive Awards and the issuance of Shares under the
Plan shall be subject to all applicable laws, rules, and regulations, and to
such approvals by any governmental agencies or national securities exchanges as
may be required. Certificates evidencing shares of Common Stock delivered under
this Plan (to the extent that such shares are so evidenced) may be subject to
such stop transfer orders and other restrictions as the Committee may deem
advisable under the rules and regulations of the Securities and Exchange
Commission, any securities exchange or transaction reporting system upon which
the Common Stock is then listed or to which it is admitted for quotation, and
any applicable federal or state securities law. The Committee may cause a legend
or legends to be placed upon such certificates to make appropriate reference to
such restrictions.

7.9     RULE 16B-3 SECURITIES LAW COMPLIANCE

        With respect to Insiders to the extent applicable, transactions under
the Plan are intended to comply with all applicable conditions of Rule 16b-3
under the Exchange Act. Any ambiguities or inconsistencies in the construction
of an Incentive Award or the Plan shall be interpreted to give

                                              38
<PAGE>
effect to such intention. However, to the extent any provision of the Plan or
action by the Committee fails to so comply, it shall be deemed null and void to
the extent permitted by law and deemed advisable by the Committee in its
discretion.

7.10    COMPLIANCE WITH CODE SECTION 162(M)

        If the Company is a Publicly Held Corporation, then unless otherwise
determined by the Committee with respect to any particular Incentive Award, it
is intended that the Plan comply fully with and meet all the requirements of
Section 162(m) of the Code so that any applicable types of Incentive Awards that
are granted to Covered Employees shall qualify for the Performance-Based
Exception. If any provision of the Plan or an Incentive Agreement would
disqualify the Plan or would not otherwise permit the Plan or Incentive Award to
comply with the Performance-Based Exception as so intended, such provision shall
be construed or deemed amended to conform to the requirements of the
Performance-Based Exception to the extent permitted by applicable law and deemed
advisable by the Committee; provided that no such construction or amendment
shall have an adverse effect on the prior grant of an Incentive Award or the
economic value to a Grantee of any outstanding Incentive Award.

7.11    SUCCESSORS

        All obligations of the Company under the Plan with respect to Incentive
Awards granted hereunder shall be binding on any successor to the Company,
whether the existence of such successor is the result of a direct or indirect
purchase, merger, consolidation, or otherwise, of all or substantially all of
the business and/or assets of the Company.

7.12    MISCELLANEOUS PROVISIONS

               (a) No Employee, Consultant, Outside Director, or other person
        shall have any claim or right to be granted an Incentive Award under the
        Plan. Neither the Plan, nor any action taken hereunder, shall be
        construed as giving any Employee, Consultant, or Outside Director any
        right to be retained in the Employment or other service of the Company
        or any Parent or Subsidiary.

               (b) No Shares of Common Stock shall be issued hereunder unless
        counsel for the Company is then reasonably satisfied that such issuance
        will be in compliance with federal and state securities laws, if
        applicable.

               (c) The expenses of the Plan shall be borne by the Company.

                                              39
<PAGE>
               (d) By accepting any Incentive Award, each Grantee and each
        person claiming by or through him shall be deemed to have indicated his
        acceptance of the Plan.

7.13    SEVERABILITY

        In the event that any provision of this Plan shall be held illegal,
invalid or unenforceable for any reason, such provision shall be fully
severable, but shall not affect the remaining provisions of the Plan, and the
Plan shall be construed and enforced as if the illegal, invalid, or
unenforceable provision was not included herein.

7.14    GENDER, TENSE AND HEADINGS

        Whenever the context so requires, words of the masculine gender used
herein shall include the feminine and neuter, and words used in the singular
shall include the plural. Section headings as used herein are inserted solely
for convenience and reference and constitute no part of the interpretation or
construction of the Plan.

7.15    GOVERNING LAW

        The Plan shall be interpreted, construed and constructed in accordance
with the laws of the State of Texas without regard to its conflicts of law
provisions, except as may be superseded by applicable laws of the United States.

        IN WITNESS WHEREOF, OEI International, Inc. has caused this Plan to be 
duly executed in its name and on its behalf by its duly authorized officer.

        parent (as defined in Section 424(e) of the Code) and each current or
        future Subsidiary which has been designated by the Board or the
        Committee as a participating employer in the Plan.

               (m) "EMPLOYMENT" means Employment as an employee or officer by
        the Company or a Subsidiary as designated in such entity's payroll
        records, or by any corporation issuing or assuming rights or obligations
        under the Plan in any transaction described in Section 424(a) of the
        Code or by a parent corporation or a subsidiary corporation of such
        corporation. In this regard, neither the transfer of a Participant from
        Employment by the Company to Employment by a Subsidiary, nor the
        transfer of a Participant from Employment by a Subsidiary to Employment
        by the Company, shall be deemed to be a termination of Employment of the
        Participant. Moreover, the Employment of a Participant shall not be
        deemed to have been terminated because of absence from active Employment
        on account of temporary illness or during authorized vacation, temporary
        leaves of absence from active Employment granted by Company or a
        Subsidiary for reasons of professional advancement, education, health,
        or government service, or during military leave for any period if the
        Participant returns to active Employment within 90 days after the
        termination of military leave, or during any period required to be
        treated as a leave of absence which, by virtue of any valid law or
        agreement, does not result in a termination of Employment.

               Any worker treated as an independent contractor by the Employer
        who is later reclassified as a common-law employee shall not be in
        Employment during any period in which such worker was treated by the
        Employer as an independent contractor. Any "leased employee", as
        described in Section 414(n) of the Code, shall not be deemed an Employee
        hereunder.

               (n) "ENTRY DATE" means the first day of each Fiscal Quarter.

                                              2
<PAGE>

               (o) "FISCAL QUARTER" means a three-consecutive-month period
        beginning on each January 1, April 1, July 1, and October 1, during the
        period beginning on the Effective Date until the Plan is terminated.

               (p) "MARKET PRICE" means, subject to the next paragraph, the
        market value of a share of Stock on any date, which shall be determined
        as (i) the closing sales price on the immediately preceding business day
        of a share of Stock as reported on the New York Stock Exchange or other
        principal securities exchange on which shares of Stock are then listed
        or admitted to trading or (ii) if not so reported, the average of the
        closing bid and asked prices for a share of Stock on the immediately
        preceding business day as quoted on the National Association of
        Securities Dealers Automated Quotation System ("NASDAQ"), or (iii) if
        not quoted on NASDAQ, the average of the closing bid and asked prices
        for a share of Stock as quoted by the National Quotation Bureau's "Pink
        Sheets" or the National Association of Securities Dealers' OTC Bulletin
        Board System. If the price of a share of Stock shall not be so reported
        pursuant to the previous sentence, the fair market value of a share of
        Stock shall be determined by the Committee in its discretion provided
        that such method is appropriate for purposes of an employee stock
        purchase plan under Section 423 of the Code.

               Notwithstanding the previous paragraph of this definition, the
        Market Price of a share of Stock solely for purposes of determining the
        option price on the first or last day of the Fiscal Quarter in
        accordance with SECTION 7(B) shall be based on the Market Price on the
        first or last day of the Fiscal Quarter, as applicable, and not on the
        immediately preceding business day. For example, if the Stock is traded
        on the New York Stock Exchange, when determining the option price under
        SECTION 7(B) at which shares of Stock are purchased, the Market Price
        for determining this option price shall be based on either (i) the first
        business day of the Fiscal Quarter or (ii) the last business day of the
        Fiscal Quarter, whichever day has the lower closing sales price.

               (q) "PARTICIPANT" means any Employee who meets the eligibility
        requirements of SECTION 3 and who has elected to and is participating in
        the Plan.

               (r) "PLAN" means the OEI International, Inc. Employee Stock
        Purchase Plan, as set forth herein, and all amendments hereto.

               (s) "STOCK" means the Common Stock (as defined above).

               (t) "SUBSIDIARY" means any domestic or foreign corporation (other
        than the Company) (i) which, pursuant to Section 424(f) of the Code, is
        included in an unbroken chain of corporations beginning with the Company
        if, at the time of the granting of the option, each of the corporations
        other than the last corporation in the unbroken chain owns stock
        possessing fifty percent (50%) or more of the total combined voting
        power of all classes of capital stock in one of the other corporations
        in such chain and (ii) which has been

                                              3
<PAGE>
        designated by the Board or the Committee as a corporation whose
        Employees are eligible to participate in the Plan.

        3.     ELIGIBILITY.

               (a) ELIGIBILITY REQUIREMENTS. Participation in the Plan is
        voluntary. Each Employee (i) whose customary Employment is at least
        twenty (20) hours a week and more than five (5) months of Employment in
        any calendar year, and (ii) who is in Employment on the Effective Date,
        or if not employed on the Effective Date, who has completed at least six
        (6) consecutive months of continuous Employment with an Employer
        (calculated from his last date of hire to the termination of his
        Employment for any reason), will be eligible to participate in the Plan
        on the first day of the payroll period commencing on or after the
        earlier of (A) the Effective Date or (B) the Entry Date on which the
        Employee satisfies the aforementioned eligibility requirements. Each
        Employee whose Employment terminates and who is rehired by an Employer
        shall be treated as a new Employee for eligibility purposes under the
        Plan.

               (b) LIMITATIONS ON ELIGIBILITY. Any provision of the Plan to the
        contrary notwithstanding, no Employee will be granted an option under
        the Plan:

                      (i) if, immediately after the grant, the Employee would
               own stock, and/or hold outstanding options to purchase stock,
               possessing five percent (5%) or more of the total combined voting
               power or value of all classes of stock of the Company or of any
               Subsidiary; or

                      (ii) which permits the Employee's rights to purchase stock
               under this Plan and all other employee stock purchase plans
               (within the meaning of Section 423 of the Code) of the Company
               and its Subsidiaries to accrue at a rate which exceeds $25,000 of
               the fair market value of the stock (determined at the time such
               option is granted) for each Fiscal year in which such option is
               outstanding at any time, all as determined in accordance with
               Section 423(b)(8) of the Code.

        For purposes of SECTION 3(B)(I) above, pursuant to Section 424(d) of the
        Code, (i) the Employee with respect to whom such limitation is being
        determined shall be considered as owning the stock owned, directly or
        indirectly, by or for his brothers and sisters (whether by the whole or
        half blood), spouse, ancestors, and lineal descendants; and (ii) stock
        owned, directly or indirectly, by or for a corporation, partnership,
        estate, or trust, shall be considered as being owned proportionately by
        or for its shareholders, partners, or beneficiaries. In addition, for
        purposes of SECTION 3(B)(II) above, pursuant to Section 423(b)(8) of the
        Code, (1) the right to purchase stock under an option accrues when the
        option (or any portion thereof) first becomes exercisable during the
        calendar year, (2) the right to purchase stock under an option accrues
        at the rate provided in the option but in no case may such rate exceed
        $25,000 of fair market value of such stock (determined at the time such
        option is granted)

                                              4
<PAGE>
        for any one calendar year, and (3) a right to purchase stock which has
        accrued under one option granted pursuant to the Plan may not be carried
        over to any other option.

        4. SHARES SUBJECT TO THE PLAN. The total number of shares of Common
Stock that may be issued upon the exercise of options granted under the Plan
will not exceed Three Hundred Thousand (300,000) shares (subject to adjustment
as provided in SECTION 17). Such shares may be originally issued shares,
treasury shares, reacquired shares, shares bought in the market, or any
combination of the foregoing. If any option which has been granted under the
Plan expires or terminates for any reason without having been exercised in full,
the unpurchased shares will again become available for purposes of the Plan. Any
shares which are not subject to outstanding options upon the termination of the
Plan shall cease to be subject to the Plan.

        5.     PARTICIPATION.

               (a) PAYROLL DEDUCTION AUTHORIZATION. An Employee shall be
        eligible to participate in the Plan as of the first Entry Date following
        such Employee's satisfaction of the eligibility requirements of SECTION
        3, or, if later, the first Entry Date following the date on which the
        Employee's Employer adopted the Plan. At least 10 days (or such other
        period as may be prescribed by the Committee or a Benefits
        Representative) prior to the first Entry Date as of which an Employee is
        eligible to participate in the Plan, the Employee shall execute and
        deliver to the Benefits Representative, on the form prescribed for such
        purpose, an authorization for payroll deductions which specifies his
        chosen rate of payroll deduction contributions pursuant to SECTION 6,
        and such other information as is required to be provided by the Employee
        on such enrollment form. The enrollment form shall authorize the
        Employer to reduce the Employee's Base Pay by the amount of such
        authorized contributions. To the extent provided by the Committee or a
        Benefits Representative, each Participant shall also be required to open
        a stock brokerage account with a brokerage firm which has been engaged
        to administer the purchase, holding and sale of Common Stock for
        Accounts under the Plan and, as a condition of participation hereunder,
        the Participant shall be required to execute any form required by the
        brokerage firm to open and maintain such brokerage account.

               (b) CONTINUING EFFECT OF PAYROLL DEDUCTION AUTHORIZATION. Payroll
        deductions for a Participant will commence with the first payroll period
        beginning after the Participant's authorization for payroll deductions
        becomes effective, and will end with the payroll period that ends when
        terminated by the Participant in accordance with SECTION 6(C) or due to
        his termination of Employment in accordance with SECTION 11. Payroll
        deductions will also cease when the Participant is suspended from
        participation due to a withdrawal of payroll deductions in accordance
        with SECTION 10. When applicable with respect to Employees who are paid
        on a hourly wage basis, the authorized payroll deductions shall be
        withheld from wages when actually paid following the period in which the
        compensatory services were rendered. Only payroll deductions that are
        credited to the Participant's Account during the

                                              5
<PAGE>

        Fiscal Quarter will be used to purchase Common Stock pursuant to SECTION
        8 regardless of when the work was performed.

               (c) EMPLOYMENT AND STOCKHOLDERS RIGHTS. Nothing in the Plan will
        confer on a Participant the right to continue in the employ of the
        Employer or will limit or restrict the right of the Employer to
        terminate the Employment of a Participant at any time with or without
        cause. A Participant will have no interest in any Common Stock to be
        purchased under the Plan or any rights as a stockholder with respect to
        such Stock until the Stock has been purchased and credited to the
        Participant's Account.

        6.     PAYROLL DEDUCTIONS.

               (a) PARTICIPANT CONTRIBUTIONS BY PAYROLL DEDUCTIONS. At the time
        a Participant files his payroll deduction authorization form, the
        Participant will elect to have deductions made from the Participant's
        Base Pay for each payroll period such authorization is in effect in
        whole percentages at the rate of not less than one percent (1%) nor more
        than fifteen percent (15%) of the Participant's Base Pay.

               (b) NO OTHER PARTICIPANT CONTRIBUTIONS PERMITTED. All payroll
        deductions made for a Participant will be credited to the Participant's
        Account under the Plan. A Participant may not make any separate cash
        payment into such Account.

               (c) CHANGES IN PARTICIPANT CONTRIBUTIONS. Subject to SECTIONS 10
        AND 22, a Participant may increase, decrease, suspend, or resume payroll
        deductions under the Plan by giving written notice to a designated
        Benefits Representative at such time and in such form as the Committee
        or Benefits Representative may prescribe from time to time. Such
        increase, decrease, suspension or resumption will be effective as of the
        first day of the first payroll period which begins as soon as
        administratively practicable after receipt of the Participant's written
        notice, but not earlier than the first day of the payroll period of the
        Fiscal Quarter next following receipt and acceptance of such form.
        Notwithstanding the previous sentence, a Participant may completely
        discontinue contributions at any time during a Fiscal Quarter, effective
        as of the first day of the payroll period as soon as administratively
        practicable following receipt of a written discontinuance notice from
        the Participant on a form provided by a designated Benefits
        Representative. Following a discontinuance of contributions, a
        Participant cannot authorize any payroll contributions to his Account
        for the remainder of the Fiscal Quarter in which the discontinuance was
        effective.

        7.     GRANTING OF OPTION TO PURCHASE STOCK.

               (a) QUARTERLY GRANT OF OPTIONS. For each Fiscal Quarter, a
        Participant will be deemed to have been granted an option to purchase,
        on the first day of the Fiscal Quarter, as many whole and fractional
        shares as may be purchased with the payroll deductions (and any

                                              6
<PAGE>

        cash dividends as provided in SECTION 8) credited to the Participant's
        Account during the Fiscal Quarter.

               (b) OPTION PRICE. The option price of the Common Stock purchased
        with the amount credited to the Participant's Account during each Fiscal
        Quarter will be the lower of:

                      (i) Ninety percent (90%) of the Market Price of a share of
               Stock on the first day of the Fiscal Quarter; or

                      (ii) Ninety percent (90%) of the Market Price of a share
               of Stock on the last day of the Fiscal Quarter.

               Only the Market Price as of the first day of the Fiscal Quarter
        and the last day of the Fiscal Quarter shall be considered for purposes
        of determining the option purchase price; interim fluctuations during
        the Fiscal Quarter shall not be considered.

        8.     EXERCISE OF OPTION.

               (a) AUTOMATIC EXERCISE OF OPTIONS. Unless a Participant has
        elected to withdraw payroll deductions in accordance with SECTION 10,
        the Participant's option for the purchase of Common Stock will be deemed
        to have been exercised automatically as of the last day of the Fiscal
        Quarter for the purchase of the number of whole and fractional shares of
        Common Stock which the accumulated payroll deductions (and cash
        dividends on the Common Stock as provided in SECTION 8(B)) in the
        Participant's Account at that time will purchase at the applicable
        option price; provided, however, the number of shares purchased for the
        Fiscal Quarter shall not exceed 20,000 shares. Fractional shares may be
        issued under the Plan. As of the last day of each Fiscal Quarter, the
        balance of each Participant's Account shall be applied to purchase the
        number of whole and fractional shares of Stock as determined by dividing
        the balance of such Participant's Account as of such date by the option
        price determined pursuant to SECTION 7(B). The Participant's Account
        shall be debited accordingly. The Committee or its delegate shall make
        all determinations with respect to applicable currency exchange rates if
        a Participant's payroll deductions are not made in U.S. dollars.

               (b) DIVIDENDS GENERALLY. Cash dividends paid on shares of Common
        Stock which have not been delivered to the Participant pending the
        Participant's request for delivery pursuant to SECTION 9(C), will be
        combined with the Participant's payroll deductions and applied to the
        purchase of Common Stock at the end of the Fiscal Quarter in which the
        cash dividends are received, subject to the Participant's withdrawal
        rights set forth in SECTION 10. Dividends paid in the form of shares of
        Common Stock or other securities with respect to shares that have been
        purchased under the Plan, but which have not been delivered to the
        Participant, will be credited to the shares that are credited to the
        Participant's Account.

                                              7
<PAGE>
               (c) PRO-RATA ALLOCATION OF AVAILABLE SHARES. If the total number
        of shares to be purchased under option by all Participants exceeds the
        number of shares authorized under SECTION 4, a pro-rata allocation of
        the available shares will be made among all Participants authorizing
        such payroll deductions based on the amount of their respective payroll
        deductions through the last day of the Fiscal Quarter.

        9.     OWNERSHIP AND DELIVERY OF SHARES.

               (a) BENEFICIAL OWNERSHIP. A Participant will be the beneficial
        owner of the shares of Common Stock purchased under the Plan on exercise
        of his option and will have all rights of beneficial ownership in such
        shares; provided, however, the Participant may not transfer or otherwise
        dispose of the shares for a period of six (6) months following the date
        on which the shares were purchased. Any dividends paid with respect to
        such shares will be credited to the Participant's Account and applied as
        provided in SECTION 8 until the shares are delivered to the Participant.

               (b) CUSTODY OF SHARES DURING RESTRICTION PERIOD. The Company, or
        a brokerage firm or other entity selected by the Company, will retain
        custody of the certificates representing the shares until the expiration
        of the six-month period in SECTION 9(A).

               (c) REGISTRATION OF STOCK. Stock to be delivered to a Participant
        under the Plan will be registered in the name of the Participant, or if
        the Participant so directs by written notice to the designated Benefits
        Representative or brokerage firm, if any, prior to the purchase of Stock
        hereunder, in the names of the Participant and one such other person as
        may be designated by the Participant, as joint tenants with rights of
        survivorship or as tenants by the entireties, to the extent permitted by
        applicable law. Any such designation shall not apply to shares purchased
        after a Participant's death by the Participant's beneficiary or estate,
        as the case may be, pursuant to SECTION 11(B). If a brokerage firm is
        engaged by the Company to administer Accounts under the Plan, such firm
        shall provide such account registration forms as are necessary for each
        Participant to open and maintain a brokerage account with such firm.

               (d) DELIVERY OF STOCK CERTIFICATES. The Company, or a brokerage
        firm or other entity selected by the Company, shall deliver to each
        Participant a certificate for the number of shares of Common Stock
        purchased by the Participant hereunder as soon as practicable after the
        close of each Fiscal Quarter. Alternatively, in the discretion of the
        Committee, the stock certificate may be delivered to a designated stock
        brokerage account maintained for the Participant and held in "street
        name" in order to facilitate the subsequent sale of the purchased
        shares. As provided in SECTION 9(A), the Participant may not transfer or
        otherwise dispose of the shares for a period of six (6) months following
        the date on which the shares were purchased.

                                              8
<PAGE>
               (e) REGULATORY APPROVAL. In the event the Company is required to
        obtain from any commission or agency the authority to issue any stock
        certificate hereunder, the Company shall seek to obtain such authority.
        The inability of the Company to obtain from any such commission or
        agency the authority which counsel for the Company deems necessary for
        the lawful issuance of any such certificate shall relieve the Company
        from liability to any Participant, except to return to the Participant
        the amount of his Account balance used to exercise the option to
        purchase the affected shares.

        10. WITHDRAWAL OF PAYROLL DEDUCTIONS. At any time during a Fiscal
Quarter, but in no event later than 15 days (or such shorter prescribed by the
Committee or a Benefits Representative) prior to the last day of the Fiscal
Quarter, a Participant may elect to abandon his election to purchase Common
Stock under the Plan. By written notice to the designated Benefits
Representative on a form provided for such purpose, the Participant may thus
elect to withdraw all of the accumulated balance in his Account being held for
the purchase of Common Stock in accordance with SECTION 8(B). Partial
withdrawals will not be permitted. All such amounts will be paid to the
Participant as soon as administratively practical after receipt of his notice of
withdrawal. After receipt and acceptance of such withdrawal notice, no further
payroll deductions will be made from the Participant's Base Pay beginning as of
the next payroll period during the Fiscal Quarter in which the withdrawal notice
is received. The Committee, in its discretion, may determine that amounts
otherwise withdrawable hereunder by Participants shall be offset by an amount
that the Committee, in its discretion, determines to be reasonable to help
defray the administrative costs of effecting the withdrawal, including, without
limitation, fees imposed by any brokerage firm which administers such
Participant's Account. After a withdrawal, an otherwise eligible Participant may
resume participation in the Plan as of the first day of the Fiscal Quarter next
following his delivery of a payroll deduction authorization pursuant to the
procedures prescribed in SECTION 5(A).

        11.    TERMINATION OF EMPLOYMENT.

               (a)    GENERAL RULE.  Upon termination of a Participant's 
        Employment for any reason, his participation in the Plan will 
        immediately terminate.

               (b) TERMINATION DUE TO RETIREMENT, DEATH OR DISABILITY. If the
        Participant's termination of Employment is due to (i) retirement from
        Employment on or after his attainment of age 65, (ii) death or (iii)
        Disability, the Participant (or the Participant's personal
        representative or legal guardian in the event of Disability, or the
        Participant's beneficiary (as defined in SECTION 14) or the
        administrator of his will or executor of his estate in the event of
        death), will have the right to elect, either to:

                      (1) Withdraw all of the cash and shares of Common Stock
               credited to the Participant's Account as of his termination date;
               or

                      (2) Exercise the Participant's option for the purchase of
               Common Stock on the last day of the Fiscal Quarter (in which
               termination of Employment occurs)

                                              9
<PAGE>

               for the purchase of the number of shares of Common Stock which
               the cash balance credited to the Participant's Account as of the
               date of the Participant's termination of Employment will purchase
               at the applicable option price.

        The Participant (or, if applicable, such other person designated in the
        first paragraph of this SECTION 11(B)) must make such election by giving
        written notice to the Benefits Representative at such time and in such
        manner as prescribed from time to time by the Committee or Benefits
        Representative. In the event that no such written notice of election is
        received by the Benefits Representative within 30 days of the
        Participant's termination of Employment date, the Participant (or such
        other designated person) will automatically be deemed to have elected to
        withdraw the balance in the Participant's Account as of his termination
        date. Thereafter, any accumulated cash and shares of Common Stock
        credited to the Participant's Account as of his termination of
        Employment date will be delivered to or on behalf of the Participant as
        soon as administratively practicable.

               (c) TERMINATION OTHER THAN FOR RETIREMENT, DEATH OR DISABILITY.
        Upon termination of a Participant's Employment for any reason other than
        retirement, death, or Disability pursuant to SECTION 11(B), the
        participation of the Participant in the Plan will immediately terminate.
        Thereafter, any accumulated cash and shares of Common Stock credited to
        the Participant's Account as of his termination of Employment date will
        be delivered to the Participant as soon as administratively practicable.

               (d) REHIRED EMPLOYEES. Any Employee whose Employment terminates
        and who is subsequently rehired by an Employer shall be treated as a new
        Employee for purposes of eligibility to participate in the Plan.

        12. INTEREST. No interest will be paid or allowed on any money paid into
the Plan or credited to the Account of any Participant.

        13.    ADMINISTRATION OF THE PLAN.

               (a) NO PARTICIPATION IN PLAN BY COMMITTEE MEMBERS. No options may
        be granted under the Plan to any member of the Committee during the term
        of his membership on the Committee.

               (b) AUTHORITY OF THE COMMITTEE. Subject to the provisions of the
        Plan, the Committee shall have the plenary authority to (a) interpret
        the Plan and all options granted under the Plan, (b) make such rules as
        it deems necessary for the proper administration of the Plan, (c) make
        all other determinations necessary or advisable for the administration
        of the Plan, and (d) correct any defect or supply any omission or
        reconcile any inconsistency in the Plan or in any option granted under
        the Plan in the manner and to the extent that the Committee deems
        advisable. Any action taken or determination made by the Committee
        pursuant to this and the other provisions of the Plan shall be
        conclusive on all parties. The

                                              10
<PAGE>

        act or determination of a majority of the Committee shall be deemed to
        be the act or determination of the Committee. By express written
        direction, or by the day-to-day operation of Plan administration, the
        Committee may delegate the authority and responsibility for the
        day-to-day administrative or ministerial tasks of the Plan to a Benefits
        Representative, including a brokerage firm or other third party engaged
        for such purpose.

               (c) MEETINGS. The Committee shall designate a chairman from among
        its members to preside at its meetings, and may designate a secretary,
        without regard to whether that person is a member of the Committee, who
        shall keep the minutes of the proceedings. Meetings shall be held at
        such times and places as shall be determined by the Committee, and the
        Committee may hold telephonic meetings. The Committee may take any
        action otherwise proper under the Plan by the affirmative vote of a
        majority of its members, taken at a meeting, or by the affirmative vote
        of all of its members taken without a meeting. The Committee may
        authorize any one or more of their members or any officer of the Company
        to execute and deliver documents on behalf of the Committee.

               (d) DECISIONS BINDING. All determinations and decisions made by
        the Committee shall be made in its discretion pursuant to the provisions
        of the Plan, and shall be final, conclusive and binding on all persons
        including the Company, Participants, and their estates and
        beneficiaries.

               (e) EXPENSES OF COMMITTEE. The Committee may employ legal
        counsel, including, without limitation, independent legal counsel and
        counsel regularly employed by the Company, consultants and agents as the
        Committee may deem appropriate for the administration of the Plan. The
        Committee may rely upon any opinion or computation received from any
        such counsel, consultant or agent. All expenses incurred by the
        Committee in interpreting and administering the Plan, including, without
        limitation, meeting expenses and professional fees, shall be paid by the
        Company.

               (f) INDEMNIFICATION. Each person who is or was a member of the
        Committee shall be indemnified by the Company against and from any
        damage, loss, liability, cost and expense that may be imposed upon or
        reasonably incurred by him in connection with or resulting from any
        claim, action, suit, or proceeding to which he may be a party or in
        which he may be involved by reason of any action taken or failure to act
        under the Plan, except for any such act or omission constituting willful
        misconduct or gross negligence. Such person shall be indemnified by the
        Company for all amounts paid by him in settlement thereof, with the
        Company's approval, or paid by him in satisfaction of any judgment in
        any such action, suit, or proceeding against him, provided he shall give
        the Company an opportunity, at its own expense, to handle and defend the
        same before he undertakes to handle and defend it on his own behalf. The
        foregoing right of indemnification shall not be exclusive of any other
        rights of indemnification to which such persons may be entitled under
        the Company's Articles of Incorporation or Bylaws, as a matter of law,
        or otherwise, or any power that the Company may have to indemnify them
        or hold them harmless.

                                              11

        14. DESIGNATION OF BENEFICIARY. At such time, in such manner, and using
such form as shall be prescribed from time to time by the Committee or a
Benefits Representative, a Participant may file a written designation of a
beneficiary who is to receive any Common Stock and/or cash credited to the
Participant's Account at the Participant's death. Upon the death of a
Participant, and receipt by the Benefits Representative of proof of the identity
of a beneficiary validly designated under the Plan, the Benefits Representative
will take appropriate action to ensure delivery of such Common Stock and/or cash
to such beneficiary.

        A Participant may, from time to time, revoke or change his beneficiary
designation by filing a new designation form with the Benefits Representative.
The last valid designation received shall be controlling; provided, however,
that no beneficiary designation, or change or revocation thereof, shall be
effective unless received prior to the Participant's death and in no event shall
it be effective as of a date prior to its receipt and acceptance by the Benefits
Representative. Notwithstanding any contrary provision of this SECTION 14, no
beneficiary designation made by a married Participant, other than one under
which the surviving lawful spouse of such Participant is designated as the sole
beneficiary, shall be valid and effective without the written consent of such
spouse.

        If no valid and effective beneficiary designation exists at the time of
the Participant's death, or if no designated beneficiary survives the
Participant, or if such designation conflicts with applicable law, the payment
of the Participant's Account balance shall be made to the Participant's
surviving lawful spouse, if any, of if there is no such surviving spouse, to the
executor or administrator of his estate. If the Committee is in doubt as to the
right of any person to receive such amount, the Committee may direct that the
amount be paid into any court of competent jurisdiction in an interpleader
action, and such payment shall be a full and complete discharge of any liability
or obligation under the Plan to the extent of such payment.

        15. TRANSFERABILITY. No amounts credited to a Participant's Account,
whether cash or Common Stock, nor any rights with regard to the exercise of an
option or to receive Common Stock under the Plan, may be assigned, transferred,
pledged, or otherwise disposed of in any way by the Participant other than by
will or the laws of descent and distribution. Any such attempted assignment,
transfer, pledge, or other disposition will be void and without effect.

        Each option shall be exercisable, during the Participant's lifetime,
only by the Employee to whom the option was granted. The Company shall not
recognize, and shall be under no duty to recognize, any assignment or purported
assignment by an employee of his option or of any rights under his option.

        16. NO RIGHTS OF STOCKHOLDER UNTIL CERTIFICATE ISSUED. With respect to
shares of Stock subject to an option, an optionee shall not be deemed to be a
stockholder, and the optionee shall not have any of the rights or privileges of
a stockholder. An optionee shall have the rights and privileges of a stockholder
when, but not until, a certificate for shares has been issued to the optionee
following exercise of his option.

                                              12

        17. CHANGES IN THE COMPANY'S CAPITAL STRUCTURE. The Board shall make or
provide for such adjustments in the maximum number of shares specified in
SECTION 4 and the number and option price of shares subject to options
outstanding under the Plan as the Board shall determine is appropriate to
prevent dilution or enlargement of the rights of Participants that otherwise
would result from any stock dividend, stock split, stock exchange, combination
of shares, recapitalization or other change in the capital structure of the
Company, merger, consolidation, spin-off of assets, reorganization, partial or
complete liquidation, issuance of rights or warrants to purchase securities, any
other corporate transaction or event having an effect similar to any of the
foregoing.

        In the event of a merger of one or more corporations into the Company,
or a consolidation of the Company and one or more corporations in which the
Company shall be the surviving corporation, each Participant, at no additional
cost, shall be entitled, upon his payment for all or part of the Common Stock
purchasable by him under the Plan, to receive (subject to any required action by
shareholders) in lieu of the number of shares of Common Stock which he was
entitled to purchase, the number and class of shares of stock or other
securities to which such holder would have been entitled pursuant to the terms
of the agreement of merger or consolidation if, immediately prior to such merger
or consolidation, such holder had been the holder of record of the number of
shares of Common Stock equal to the number of shares purchasable by the
Participant hereunder.

        If the Company shall not be the surviving corporation in any
reorganization, merger or consolidation (or survives only as a subsidiary of an
entity other than a previously wholly-owned subsidiary of the Company), or if
the Company is to be dissolved or liquidated or sell substantially all of its
assets or stock to another corporation or other entity, then (i) the date of
exercise for all options then outstanding may be accelerated to a date fixed by
the Committee prior to the effective date of such corporate event, (ii) a
Participant may, at his election by written notice to the Company, either (x)
withdraw from the Plan pursuant to SECTION 10 and receive a full distribution of
the cash and Stock balance credited to his Account, or (y) fully exercise
pursuant to SECTION 8(A) his outstanding options as of such exercise date to
purchase shares of Stock, at the option price, to the extent of the cash balance
in the Participant's Account pursuant to SECTION 8(A) and, in such event, the
date fixed by the Committee shall be deemed the last day of the Fiscal Quarter
for purposes of SECTION 8(A). If the Participant fails to provide the notice of
exercise within three business days after the date selected by the Committee,
the Participant shall be conclusively deemed to have requested to receive full
payment of the accumulated balance of his Account. After the date fixed by the
Committee, the six month holding period requirement of SECTION 9(A) will no
longer be effective and thus the shares may be transferred within such 6-month
period. The date the Committee selects for the exercise date shall be deemed to
be the exercise date for purposes of computing the option price pursuant to
SECTION 7(B). If the Participant elects to exercise his outstanding options, the
Company shall deliver to such Participant a stock certificate issued pursuant to
SECTION 9(D) for the number of shares with respect to which such options were
exercised. The Committee shall take such steps in connection with such
transactions as the Committee deems necessary or appropriate to assure that the
provisions of this SECTION 17 are effectuated for the benefit of the
Participants.

                                              13
<PAGE>

        Except as expressly provided in this SECTION 17, the issue by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, for cash or property, or for labor or services either
upon direct sale or upon the exercise of rights or warrants to subscribe
therefor, or upon conversion of shares or obligations of the Company convertible
into such shares or other securities, shall not affect, and no adjustment by
reason thereof shall be made with respect to, the number or price of shares of
Stock then available for purchase under the Plan.

        18. PLAN EXPENSES; USE OF FUNDS; NO INTEREST PAID. The expenses of the
Plan shall be paid by the Company except as otherwise provided herein or under
the terms and conditions of any agreement entered into between the Participant
and any brokerage firm engaged to administer Accounts. All funds received or
held by the Company under the Plan shall be included in the general funds of the
Company free of any trust or other restriction, and may be used for any
corporate purpose. No interest shall be paid to any Participant or credited to
his Account under the Plan.

        19. TERM OF THE PLAN. The Plan shall become effective as of April
8,1998, subject to approval by the holders of the majority of the Common Stock
present and represented at a special or annual meeting of the Company's
stockholders held on or before 12 months from April 8, 1998.

        Except with respect to options then outstanding, if not terminated
sooner under the provisions of SECTION 20, no further options shall be granted
under the Plan at the EARLIER of (i) April 7, 2008, or (ii) the point in time
when no shares of Stock reserved for issuance under SECTION 4 are available.

        20. AMENDMENT OR TERMINATION OF THE PLAN. The Board shall have the
plenary authority to terminate or amend the Plan; provided, however, that the
Board shall not, without the approval of the stockholders of the Company, (a)
increase the maximum number of shares which may be issued under the Plan
pursuant to SECTION 4, (b) amend the requirements as to the class of employees
eligible to purchase Stock under the Plan, or (c) permit the members of the
Committee to purchase Stock under the Plan. No termination, modification, or
amendment of the Plan shall adversely affect the rights of a Participant with
respect to an option previously granted to him under such option without his
written consent.

        In addition, to the extent that the Committee determines that, in the
opinion of counsel, (a) the listing for qualification requirements of any
national securities exchange or quotation system on which the Company's Common
Stock is then listed or quoted, or (b) the Code or Treasury regulations issued
thereunder, require stockholder approval in order to maintain compliance with
such listing or qualification requirements or to maintain any favorable tax
advantages or qualifications, then the Plan shall not be amended by the Board in
such respect without first obtaining such required approval of the Company's
stockholders.

        21. SECURITIES LAWS RESTRICTIONS ON EXERCISE. The Committee may, in its
discretion, require as conditions to the exercise of any option that the shares
of Common Stock reserved for issuance upon the exercise of the option shall have
been duly listed, upon official notice of issuance, upon a stock exchange, and
that either:

                                              14
<PAGE>

               (a) a Registration Statement under the Securities Act of 1933, as
        amended, with respect to said shares shall be effective; or

               (b) the participant shall have represented at the time of
        purchase, in form and substance satisfactory to the Company, that it is
        his intention to purchase the Stock for investment and not for resale or
        distribution.

        22. SECTION 16 COMPLIANCE. The Plan, and transactions hereunder by
persons subject to Section 16 of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), are intended to comply with all applicable conditions of
the exemption under Rule 16b-3 or any successor exemption provision promulgated
under the Exchange Act.

        23. WITHHOLDING TAXES FOR DISQUALIFYING DISPOSITION. Whenever shares of
Stock that were received upon the exercise of an option granted under the Plan
are disposed of within two years after the date of grant of such option or one
year from the date of exercise of such option (within the meaning of Section
423(a)(1)), the Company shall have the right to require the Participant to remit
to the Company in cash an amount sufficient to satisfy federal, state and local
withholding and payroll tax requirements, if any, attributable to such
disposition prior to authorizing such disposition or permitting the delivery of
any certificate or certificates with respect thereto.

        24. NO RESTRICTION ON CORPORATE ACTION. Subject to SECTION 20, nothing
contained in the Plan shall be construed to prevent the Board or any Employer
from taking any corporate action which is deemed by the Employer to be
appropriate or in its best interest, whether or not such action would have an
adverse effect on the Plan or any option granted under the Plan. No Employee,
beneficiary or other person shall have any claim against any Employer as a
result of any such action.

        25. USE OF FUNDS. The Employers shall promptly transfer all amounts
withheld under SECTION 6 to the Company or to any brokerage firm engaged to
administer Accounts, as directed by the Company. All payroll deductions received
or held by the Company under the Plan may be used by the Company for any
corporate purpose, and the Company will not be obligated to segregate such
payroll deductions.

        26.    MISCELLANEOUS.

               (a) OPTIONS CARRY SAME RIGHTS AND PRIVILEGES. To the extent
        required to comply with the requirements of Section 423 of the Code, all
        Employees granted options under the Plan to purchase Common Stock shall
        have the same rights and privileges hereunder.

               (b) HEADINGS. Any headings or subheadings in this Plan are
        inserted for convenience of reference only and are to be ignored in the
        construction or interpretation of any provisions hereof.

                                              15
<PAGE>

               (c) GENDER AND TENSE. Any words herein used in the masculine
        shall be read and construed in the feminine when appropriate. Words in
        the singular shall be read and construed as though in the plural, and
        vice-versa, when appropriate.

               (d) GOVERNING LAW. This Plan shall be governed and construed in
        accordance with the laws of the State of Texas without regard to its
        conflicts of law provisions, to the extent not preempted by federal law.

               (e) REGULATORY APPROVALS AND COMPLIANCE. The Company's obligation
        to sell and deliver Common Stock under the Plan is at all times subject
        to all approvals of and compliance with the (i) regulations of any
        applicable stock exchanges and (ii) any governmental authorities
        required in connection with the authorization, issuance, sale or
        delivery of such Stock, as well as federal, state and foreign securities
        laws.

               (f) SEVERABILITY. In the event that any provision of this Plan
        shall be held illegal, invalid, or unenforceable for any reason, such
        provision shall be fully severable, but shall not affect the remaining
        provisions of the Plan, and the Plan shall be construed and enforced as
        if the illegal, invalid, or unenforceable provision had not been
        included herein.

               (g) REFUND OF CONTRIBUTIONS ON NONCOMPLIANCE WITH TAX LAW. In the
        event the Company should receive notice that this Plan fails to qualify
        as an "employee stock purchase plan" under Section 423 of the Code, all
        then-existing Account balances will be paid to the Participants and the
        Plan shall immediately terminate.

               (h) NO GUARANTEE OF TAX CONSEQUENCES. The Board, Employer and the
        Committee do not make any commitment or guarantee that any tax treatment
        will apply or be available to any person participating or eligible to
        participate in the Plan, including, without limitation, any tax imposed
        by the United States or any state thereof, any estate tax, or any tax
        imposed by a foreign government.

               (i) COMPANY AS AGENT FOR THE EMPLOYERS. Each Employer, by
        adopting the Plan, appoints the Company and the Board as its agents to
        exercise on its behalf all of the powers and authorities hereby
        conferred upon the Company and the Board by the terms of the Plan,
        including, but not by way of limitation, the power to amend and
        terminate the Plan.

        IN WITNESS WHEREOF, this Plan is hereby executed by a duly authorized
officer of the Company, to be effective as of April 8, 1998.

                             OEI INTERNATIONAL, INC.

                              By: /s/ GARY J. COURY
                                  Gary J. Coury, President

                                              17



                                                                    EXHIBIT 10.3

                            INDEMNIFICATION AGREEMENT

        This Indemnification Agreement is entered into and effective as of the
______ day of ____________________, 1998 ("Agreement"), by and between OEI
International, Inc., a Delaware corporation ("Company"), and _____________
("Indemnitee"):

        WHEREAS, highly competent persons have become more reluctant to serve
corporations as directors, executive officers or in other capacities unless they
are provided, with adequate protection through insurance or adequate
indemnification against inordinate risks of claims and actions against them
arising out of their service to, and activities on behalf of, the corporation;

        WHEREAS, the Board of Directors of the Company (the "Board") has
determined that, in order to attract and retain qualified individuals, the
Company will attempt to maintain on an ongoing basis, at its sole expense,
liability insurance to protect persons' serving the Company and its subsidiaries
from certain liabilities. Although the furnishing of such insurance has been a
customary and widespread practice among United States-based corporations and
other business enterprises, the Company believes that, given current market
conditions and trends, such insurance may be available to it in the future only
at higher premiums and with more exclusions. At the same time, directors,
officers and other persons in service to corporations or business enterprises
are being increasingly subjected to expensive and time-consuming litigation
relating to, among other things, matters that traditionally would have been
brought only against the corporation or business enterprise itself;

        WHEREAS, the uncertainties relating to such insurance and to
indemnification have increased the difficulty of attracting and retaining such
persons;

        WHEREAS, the Board has determined that the increased difficulty in
attracting and retaining such persons is detrimental to the best interests of
the Company's stockholders and that the Company should act to assure such
persons that there will be increased certainty of such protection in the future;

        WHEREAS, it is reasonable, prudent and necessary for the Company
contractually to obligate itself to indemnify such persons to the fullest extent
permitted by applicable law so that they will serve or continue to serve the
Company free from undue concern that they will not be so indemnified; and

        WHEREAS, indemnitee is willing to serve, continue to serve and to take
on additional service for or on behalf of the Company on the condition that he
be so indemnified;

        NOW, THEREFORE, in consideration of the premises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:
<PAGE>
        SECTION 1. SERVICES BY INDEMNITEE. Indemnitee agrees to serve as a
director/executive officer of the Company and, as mutually agreed by Indemnitee
and the Company, as a director, officer, employee, agent or fiduciary of other
corporations, partnerships, joint ventures, trusts or other enterprises
(including, without limitation, employee benefit plans). Indemnitee may at any
time and for any reason resign from any such position (subject to any other
contractual obligation or any obligation imposed by operation of law), in which
event the Company shall have no obligation under this Agreement to continue
Indemnitee in that position. This Agreement shall not be deemed an employment
contract between the Company (or any of its subsidiaries) and Indemnitee.
Indemnitee specifically acknowledges that Indemnitee's employment with the
Company (or any of its subsidiaries), if any, is at will, and the Indemnitee may
be discharged at any time for any reason, with or without cause, except as may
be otherwise provided in any written employment contract between Indemnitee and
the Company (or any of its subsidiaries), other applicable formal severance
policies duly adopted by the Board or, with respect to service as a director of
the Company, by the Company's Certificate of incorporation, Bylaws and the
General Corporation Law of the State of Delaware. Notwithstanding, the
foregoing, this Agreement shall continue in force after Indemnitee has ceased to
serve as an officer or director of the Company and no longer serves at the
request of the Company as a director, officer, employee or agent of the Company
or any subsidiary of the Company.

        SECTION 2. INDEMNIFICATION--GENERAL. The Company shall indemnify, and
advance Expenses (as hereinafter defined) to, Indemnitee (a) as provided in this
Agreement and (b) to the fullest extent permitted by applicable law in effect on
the date hereof and as amended from time to time. The rights of Indemnitee
provided under the preceding sentence shall include, but shall not be limited
to, the rights set forth in the other Sections of this Agreement.

        SECTION 3. PROCEEDINGS OTHER THAN PROCEEDINGS BY OR IN THE RIGHT OF THE
COMPANY. Indemnitee shall be entitled to the rights of indemnification provided
in Section 2 and this Section 3 if, by reason of his Corporate Status (as
hereinafter defined), he is, or is threatened to be made, a party to or a
participant in any threatened, pending, or completed Proceeding (as hereinafter
defined), other than a Proceeding by or in the right of the Company. Pursuant to
this Section 3, the Company shall indemnify Indemnitee against, and shall hold
Indemnitee harmless from and in respect of, all Expenses, judgments, penalties,
fines (including excise taxes) and amounts paid in settlement (including all
interest, assessments and other charges paid or payable in connection with or in
respect of such Expenses, judgments, fines, penalties or amounts paid in
settlement) actually and reasonably incurred by him or on his behalf in
connection with such Proceeding or any claim, issue or matter therein, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Company and, with respect to any criminal
Proceeding, had no reasonable cause to believe his conduct was unlawful.

        SECTION 4. PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY. Indemnitee
shall be entitled to the rights of indemnification provided in Section 2 and
this Section 4 if, by reason of his Corporate Status, he is, or is threatened to
be made, a party to or a participant in any threatened, pending or completed
Proceeding brought by or in the right of the Company to procure a judgment in
its favor. Pursuant to this Section 4, the Company shall indemnify Indemnitee
against, and shall

                                              2
<PAGE>
hold Indemnitee harmless from and in respect of, all Expenses actually and
reasonably incurred by him or on his behalf in connection with, and any amounts
paid in settlement of, such Proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Company. Notwithstanding the foregoing, no indemnification against such Expenses
shall be made in respect of any claim, issue or matter in such Proceeding as to
which Indemnitee shall have been adjudged to be liable to the Company if
applicable law prohibits such indemnification; PROVIDED, HOWEVER, if applicable
law so permits, indemnification against such Expenses shall nevertheless be made
by the Company in such event if and only to the extent that the Court of
Chancery of the State of Delaware, or the court in which such Proceeding shall
have been brought or is pending, shall determine.

        SECTION 5. INDEMNIFICATION FOR EXPENSES OF A PARTY WHO IS WHOLLY OR
PARTLY SUCCESSFUL. Notwithstanding any other provision of this Agreement, to the
extent that Indemnitee is, by reason of his Corporate Status, a party to (or a
participant in) and is successful, on the merits or otherwise, in defense of any
Proceeding, he shall be indemnified against all Expenses actually and reasonably
incurred by him or on his behalf in connection therewith. If Indemnitee is not
wholly successful in defense of such Proceeding but is successful, on the merits
or otherwise, as to one or more but less than all claims, issues or matters in
such Proceeding, the Company shall indemnify Indemnitee against all Expenses
actually and reasonably incurred by him or on his behalf in connection with each
successfully resolved claim, issue or matter. For purposes of this Section and
without limitation, the termination of any claim, issue or matter in such a
Proceeding by dismissal, with or without prejudice, shall be deemed to be a
successful result as to such claim, issue or matter.

        SECTION 6. INDEMNIFICATION FOR EXPENSES AS A WITNESS. Notwithstanding
any other provision of this Agreement, to the extent that Indemnitee is, by
reason of his Corporate Status, a witness in any Proceeding to which Indemnitee
is not a party, he shall be indemnified against all Expenses actually and
reasonably incurred by him or on his behalf in connection therewith.

        SECTION 7. ADVANCEMENT OF EXPENSES. The Company shall advance all
reasonable Expenses incurred by or on behalf of Indemnitee in connection with
any Proceeding within ten (10) days after the receipt by the Company of a
statement or statements from Indemnitee requesting such advance or advances from
time to time, whether prior to or after final disposition of such Proceeding.
Such statement or statements shall reasonably evidence the Expenses incurred by
Indemnitee and shall include or be preceded or accompanied by an undertaking by
or on behalf of Indemnitee to repay any Expenses advanced if it ultimately shall
be determined, in accordance with this Agreement, that Indemnitee is not
entitled to be indemnified against such Expenses.

        SECTION 8. PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO 
                   INDEMNIFICATION.

        (a) To obtain indemnification under this Agreement, Indemnitee shall
submit to the Company a written request, including therein or therewith such
documentation and information as is reasonably available to Indemnitee and is
reasonably necessary to determine whether and to what extent Indemnitee is
entitled to indemnification. The Secretary of the Company shall, promptly upon
receipt of such a request for indemnification, advise the Board in writing that
Indemnitee has

                                              3
<PAGE>
requested indemnification.

        (b) On written request by Indemnitee for indemnification pursuant to the
first sentence of Section 8(a), a determination, if required by applicable law,
with respect to Indemnitee's entitlement thereto shall be made in the specific
case: (i) if a Change in Control (as hereinafter defined) shall have occurred
within two (2) years prior to the date of such written request, by Independent
Counsel (as hereinafter defined) in a written opinion to the Board, a copy of
which shall be delivered to Indemnitee; or (ii) if a Change of Control shall not
have occurred within two (2) years prior to the date of such written request,
(A) by a majority vote of the Disinterested Directors (as hereinafter defined),
even though less than a quorum of the Board, or (B) if there are no such
Disinterested Directors, or if such Disinterested Directors so direct, by
Independent Counsel in a written opinion to the Board, a copy of which shall be
delivered to Indemnitee; and, if it is so determined that Indemnitee is entitled
to indemnification, payment to Indemnitee shall be made within ten (10) days
after such determination. Indemnitee shall cooperate with the person, persons or
entity making such determination with respect to Indemnitee's entitlement to
indemnification, including providing to such person, persons or entity on
reasonable advance request any documentation or information which is not
privileged or otherwise protected from disclosure and which is reasonably
available to Indemnitee and reasonably necessary to such determination. Any
costs or expenses (including attorneys' fees and disbursements) incurred by
Indemnitee in so cooperating with the person, persons or entity making such
determination shall be borne by the Company (irrespective of the determination
as to Indemnitee's entitlement to indemnification) and the Company hereby
indemnifies and agrees to hold Indemnitee harmless therefrom.

        (c) In the event the determination of entitlement to indemnification is
to be made by Independent Counsel pursuant to Section 8(b), the Independent
Counsel shall be selected as provided in this Section 8(c). If a Change of
Control shall not have occurred within two (2) years prior to the date of
Indemnitee's written request for indemnification pursuant to Section 8(a), the
Independent Counsel shall be selected by the Board, and the Company shall give
written notice to Indemnitee advising him of the identity of the Independent
Counsel so selected. If a Change of Control shall have occurred within two (2)
years prior to the date of Indemnitee's written request for indemnification
pursuant to Section 8(a), the Independent Counsel shall be selected by
Indemnitee (unless Indemnitee shall request that such selection be made by the
Board, in which event the preceding sentence shall apply), and Indemnitee shall
give written notice to the Company advising it of the identity of the
Independent Counsel so selected in either event, Indemnitee or the Company, as
the case may be, may, within ten (10) days after such written notice of
selection shall have been given, deliver to the Company or to Indemnitee, as the
case may be, a written objection to such selection. Such objection may be
asserted only on the ground that the Independent Counsel so selected does not
meet the requirements of "Independent Counsel" as defined in section 17, and the
objection shall set forth with particularity the factual basis of such
assertion. If such written objection is so made and substantiated, the
Independent Counsel so selected may not serve as Independent Counsel unless and
until such objection is withdrawn or a court has determined that such objection
is without merit. If, within twenty (20) days after submission by Indemnitee of
a written request for indemnification pursuant to Section 8(a), no Independent
Counsel shall have been

                                              4
<PAGE>
selected and not objected to, either the Company or Indemnitee may petition the
Court of Chancery or other court of competent jurisdiction for resolution of any
objection which shall have been made by the Company or Indemnitee to the other's
selection of Independent Counsel and/or for the appointment as Independent
Counsel of a person selected by the petitioned court or by such other person as
the petitioned court shall designate, and the person with respect to whom all
objections are so resolved or the person so appointed shall act as Independent
Counsel under Section 8(b). The Company shall pay any and all reasonable fees
and expenses of Independent Counsel incurred by such Independent Counsel in
connection with acting pursuant to Section 8(b), and the Company shall pay all
reasonable fees and expenses incident to the procedures of this Section 8(c),
regardless of the manner in which such Independent Counsel was selected and
appointed. If (i) Independent Counsel does not make any determination respecting
Indemnitee's entitlement to indemnification hereunder within ninety (90) days
after receipt by the Company of a written request therefor and (ii) any judicial
proceeding or arbitration pursuant to Section 10(a)(iii) hereof is then
commenced, Independent Counsel shall be discharged and relieved of any further
responsibility in such capacity (subject to the applicable standards of
professional conduct then prevailing).

        SECTION 9.    PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS.

        (a) In making a determination with respect to entitlement to
indemnification hereunder, the Person, Persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under
this Agreement if Indemnitee has submitted a request for indemnification in
accordance with Section 8(a), and the Company shall have the burden of proof to
overcome that presumption in connection with the making by any person, persons
or entity of any determination contrary to that presumption.

        (b) The termination of any Proceeding or of any claim, issue or matter
therein, by judgment, order, settlement or conviction, or on a plea of NOLO
CONTENDERE or its equivalent, shall not (except as otherwise expressly provided
in this Agreement) of itself adversely affect the right of Indemnitee to
indemnification or create a presumption that Indemnitee did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Company or, with respect to any criminal Proceeding,
that Indemnitee had reasonable cause to believe that his conduct was unlawful.

        (c) Any action taken by Indemnitee in connection with any employee
benefit plan shall, if taken in good faith by Indemnitee and in a manner
Indemnitee reasonably believed to be in the interest of the participants in or
beneficiaries of that plan, be deemed to have been taken in a manner "not
opposed to the best interests of the Company" for all purposes of this
Agreement.

        SECTION 10.  REMEDIES OF INDEMNITEE.

        (a) In the event that (i) a determination is made pursuant to Section 8
that Indemnitee is not entitled to indemnification hereunder, (ii) advancement
of Expenses is not timely made pursuant to Section 7, (iii) Independent Counsel
is to determine Indemnitee's entitlement to indemnification hereunder, but does
not make that determination within ninety (90) days after receipt by the

                                              5
<PAGE>
Company of the request for that indemnification, (iv) payment of indemnification
is not made pursuant to section 5 or 6 within ten (10) days after receipt by the
Company of a written request therefor or (v) payment of indemnification is not
made within ten (10) days after a determination has been made that Indemnitee is
entitled to indemnification, Indemnitee shall be entitled to an adjudication
from the Court of Chancery of his entitlement to such indemnification or
advancement of Expenses. Alternatively, Indemnitee, at his option, may seek an
award in arbitration to be conducted by a single arbitrator pursuant to the
Commercial Arbitration Rules of the American Arbitration Association. Indemnitee
shall commence such Proceeding seeking an adjudication or an award in
arbitration within one hundred eighty (180) days following the date on which
Indemnitee first has the right to commence such proceeding pursuant to this
Section 10(a); PROVIDED, HOWEVER, that the foregoing clause shall not apply in
respect of a proceeding brought by Indemnitee to enforce his rights under
Section 5.

        (b) In the event that a determination shall have been made pursuant to
Section 8(b) that Indemnitee is not entitled to indemnification, any judicial
proceeding or arbitration commenced pursuant to this Section 10 shall be
conducted in all respects as a DE NOVO trial, or arbitration, on the merits and
Indemnitee shall not be prejudiced by reason of that adverse determination. In
any judicial proceeding or arbitration commenced pursuant to this section 10,
the Company shall have the burden of proving that Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be.

        (c) If a determination shall have been made pursuant to Section 8(b)
that Indemnitee is entitled to indemnification, the Company shall be bound by
such determination in any judicial proceeding or arbitration commenced pursuant
to this Section 10, absent (i) a misstatement by Indemnitee of a material fact,
or an omission by Indemnitee of a material fact necessary to make Indemnitee's
statement not materially misleading, in connection with the request for
indemnification, or (ii) a prohibition of such indemnification under applicable
law.

        (d) In the event that Indemnitee, pursuant to this Section 10, seeks a
judicial adjudication of or an award in arbitration to enforce his rights under,
or to recover damages for breach of, this Agreement, Indemnitee shall be
entitled to recover from the Company, and shall be indemnified by the Company
against, any and all expenses (of the types described in the definition of
Expenses in Section 17) actually and reasonably incurred by him in such judicial
adjudication or arbitration, but only if he prevails therein. If it shall be
determined in said judicial adjudication or arbitration that Indemnitee is
entitled to receive part but not all of the indemnification or advancement of
expenses sought, the expenses incurred by Indemnitee in connection with such
judicial adjudication or arbitration shall be appropriately prorated.

        SECTION 11.  NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; 
                     SUBROGATION.

        (a) The rights of indemnification and to receive advancement of Expenses
as provided by this Agreement shall not be deemed exclusive of any other rights
to which Indemnitee may at any time be entitled under applicable law, the
Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders
or a resolution of directors, or otherwise. No amendment, alteration or repeal

                                              6
<PAGE>
of this Agreement or of any provision hereof shall limit or restrict any right
of Indemnitee under this Agreement in respect of any action taken or omitted by
such Indemnitee in his Corporate Status prior to such amendment, alteration or
repeal. To the extent that a change in Delaware law (whether by statute or
judicial decision) permits greater indemnification by agreement than would be
afforded currently under this Agreement, it is the intent of the parties hereto
that Indemnitee shall enjoy by this Agreement the greater benefits so afforded
by such change.

        (b) To the extent that the Company maintains an insurance policy or
policies providing liability insurance for directors, officers, employees, or
agents of the Company or of any other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise which such person serves at the
request of the Company, Indemnitee shall be covered by such policy or policies
in accordance with its or their terms to the maximum extent of the coverage
available for any such director, Officer, employee or agent under such policy or
policies.

        (c) In the event of any payment under this Agreement, the Company shall
be subrogated to the extent of such payment to all the rights of recovery of
Indemnitee, who shall execute all papers required and take all action necessary
to secure such rights, including execution of such documents as are necessary to
enable the Company to bring suit to enforce such rights.

        (d) The Company shall not be liable under this Agreement to make any
payment of amounts otherwise indemnifiable hereunder if and to the extent that
Indemnitee has otherwise actually received such payment under any insurance
policy, contract, agreement or otherwise.

        (e) The Company's obligation to indemnify or advance Expenses hereunder
to Indemnitee with respect to Indemnitee's service at the request of the Company
as a director, officer, employee or agent of any other corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise shall be reduced
by any amount Indemnitee has actually received as indemnification or advancement
of Expenses from such other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise.

        SECTION 12. DURATION OF AGREEMENT. This Agreement shall continue until
and terminate upon the later of: (a) ten (10) years after the date that
Indemnitee shall have ceased to serve as a director or officer of the Company or
of any other corporation, partnership, joint venture, trust, employee benefit
plan or other enterprise which Indemnitee served on behalf of the Company; or
(b) the final termination of any Proceeding then pending in respect of which
Indemnitee is granted rights of indemnification or advancement of expenses
hereunder and of any Proceeding commenced by Indemnitee pursuant to Section 10
relating thereto. This Agreement shall be binding upon the Company and its
successors and assigns and shall inure to the benefit of Indemnitee and his
spouse (if Indemnitee resides in Texas or another community property state),
heirs, executors and administrators, and this Agreement does not, and shall not
be construed to confer any rights on any person that is not a party to this
Agreement, other than Indemnitee's spouse, and his heirs, executors and assigns.

                                              7

        SECTION 13. SEVERABILITY. If any provision or provisions of this
Agreement shall be held to be invalid, illegal or unenforceable for any reason
whatsoever: (a) the validity, legality and enforceability of the remaining
provisions of this Agreement (including, without limitation, each portion of any
Section of this Agreement containing any such provision held to be invalid,
illegal or unenforceable which is not itself invalid, illegal or unenforceable)
shall not in any way be affected or impaired thereby; (b) such provision or
provisions shall be deemed reformed to the extent necessary to conform to
applicable law and to give the maximum effect to the intent of the parties
hereto; and (c) to the fullest extent possible, the provisions of this Agreement
(including. without limitation, each portion of any Section of this Agreement
containing any such provision held to be invalid, illegal or unenforceable which
is not itself invalid, illegal or unenforceable) shall be construed so as to
give effect to the intent manifested thereby.

        SECTION 14. EXCEPTION TO RIGHT OF INDEMNIFICATION OR ADVANCEMENT OF
EXPENSES. Notwithstanding any other provision hereof, Indemnitee shall not be
entitled to indemnification or advancement of Expenses under this Agreement with
respect to any Proceeding brought by Indemnitee or any claim therein prior to a
Change in Control, unless the bringing of such Proceeding or making of such
claim shall have been approved by the Board of Directors.

        SECTION 15. IDENTICAL COUNTERPARTS. This Agreement may be executed in
one or more counterparts by means of original or facsimile signatures, each of
which shall for all purposes be deemed to be an original but all of which
together shall constitute one and the same Agreement. Only one such counterpart
signed by the party against whom enforceability is sought needs to be produced
to evidence the existence of this Agreement.

        SECTION 16. HEADINGS. The headings of the Sections hereof are inserted
for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction thereof.

        SECTION 17.  DEFINITIONS.  For purposes of this Agreement:

               (a) "Acquiring Person" means any Person who or which, together
        with all Affiliates and Associates of such Person, is or are the
        Beneficial Owner of twenty-five percent (25%) or more of the shares of
        Common Stock then outstanding, but does not include any Exempt Person;
        PROVIDED, HOWEVER, that a Person shall not be or become an Acquiring
        Person if such Person, together with its Affiliates and Associates,
        shall become the Beneficial Owner of twenty-five percent (25%) or more
        of the shares of Common Stock then outstanding solely as a result of a
        reduction in the number of shares of Common Stock outstanding due to the
        repurchase of Common Stock by the Company, unless and until such time as
        such Person or any Affiliate or Associate of such Person shall purchase
        or otherwise become the Beneficial Owner of additional shares of Common
        Stock constituting one percent (1%) or more of the then outstanding
        shares of Common Stock or any other Person (or Persons) who is (or
        collectively are) the Beneficial Owner of shares of Common Stock
        constituting one percent (1%) or more of the then outstanding shares of

<PAGE>
        Common Stock shall become an Affiliate or Associate of such Person,
        unless, in either such case, such Person, together with all Affiliates
        and Associates of such Person, is not then the Beneficial Owner of
        twenty-five percent (25%) or more of the shares of Common Stock then
        outstanding.

               (b) "Affiliate" has the meaning ascribed to that term in Exchange
        Act Rule 12b-2.

               (c) "Associate" means, with reference to any Person, (i) any
        corporation, firm, partnership, association, unincorporated organization
        or other entity (other than the Company or a subsidiary of the Company)
        of which that Person is an officer or general partner (or officer or
        general partner of a general partner) or is, directly or indirectly, the
        Beneficial owner of 10% or more of any class of its equity securities,
        (ii) any trust or other estate in which that Person has a substantial
        beneficial interest or for or of which that Person serves as trustee or
        in a similar fiduciary capacity and (iii) any relative or spouse of that

        Person.

               (d) A specified Person is deemed the "Beneficial Owner" of, and
        is deemed to "beneficially own," any securities:

                      (i) of which that Person or any of that Person's
               Affiliates or Associates, directly or indirectly, is the
               "beneficial owner" (as determined pursuant to Exchange Act Rule
               13d-3) or otherwise has the right to vote or dispose of,
               including pursuant to any agreement, arrangement or understanding
               (whether or not in writing); PROVIDED, HOWEVER, that a Person
               shall not be deemed the "Beneficial Owner" of, or to
               "beneficially own," any security under this subparagraph as a
               result of an agreement, arrangement or understanding to vote that
               security if that agreement, arrangement or understanding: (A)
               arises solely from a revocable proxy or consent given in response
               to a public (that is, not including a solicitation exempted by
               Exchange Act Rule 14a-2(b)(2)) proxy or consent solicitation made
               pursuant to, and in accordance with, the applicable provisions of
               the Exchange Act; and (B) is not then reportable by such Person
               on Exchange Act Schedule 13D (or any comparable or successor
               report);

                      (ii) which that Person or any of that Person's Affiliates
               or Associates, directly or indirectly, has the right or
               obligation to acquire (whether that right or obligation is
               exercisable or effective immediately or only after the passage of
               time or the occurrence of an event) pursuant to any agreement,
               arrangement or understanding (whether or not in writing) or on
               the exercise of conversion rights, exchange rights, other rights,
               warrants or options, or otherwise; PROVIDED, HOWEVER, that a
               Person shall not be deemed the "Beneficial Owner" of, or to
               "beneficially own," securities tendered

                                              9
<PAGE>
               pursuant to a tender or exchange offer made by that Person or any
               of that Person's Affiliates or Associates until those tendered
               securities are accepted for purchase or exchange; or

                      (iii) which are beneficially owned, directly or
               indirectly, by (A) any other Person (or any Affiliate or
               Associate thereof) with which the specified Person or any of the
               specified Person's Affiliates or Associates has any agreement,
               arrangement or understanding (whether or not in writing) for the
               purpose of acquiring, holding, voting (except pursuant to a
               revocable proxy or consent as described in the proviso to
               subparagraph (i) of this definition) or disposing of any voting
               securities of the Company or (B) any group (as that term is used
               in Exchange Act Rule 13d-5(b)) of which that specified Person is
               a member;

PROVIDED, HOWEVER, that nothing in this definition shall cause a Person engaged
in business as an underwriter of securities to be the "Beneficial Owner" of, or
to "beneficially own," any securities acquired through such Person's
participation in good faith in a firm commitment underwriting until the
expiration of forty (40) days after the date of that acquisition. For purposes
of this Agreement, "voting" a security shall include voting, granting a proxy,
acting by consent, making a request or demand relating to corporate action
(including, without limitation, calling a stockholder meeting) or otherwise
giving an authorization (within the meaning of Section 14(a) of the Exchange
Act) in respect of such security.

               (e) "Change of Control" means the occurrence of any of the
        following events that occurs after the IPO Closing Date: (i) any Person
        becomes an Acquiring Person; (ii) at any time the then Continuing
        Directors cease to constitute a majority of the members of the Board;
        (iii) a merger of the Company with or into, or a sale by the Company of
        its properties and assets substantially as an entirety to, another
        Person occurs and, immediately after that occurrence, any Person, other
        than an Exempt Person, together with all Affiliates and Associates of

        WHEREAS, on the date of this Agreement, the Company, Petrocon
Engineering, Inc. ("PETROCON"), PEI Acquisition, Inc., a Texas corporation and a
wholly owned subsidiary of OEI (the "MERGER SUBSIDIARY"), and the stockholders
of Petrocon, including the Executive, are entering into an Agreement and Plan of
Reorganization (the "ACQUISITION AGREEMENT"), under which Petrocon will merge
with the Merger Subsidiary in a merger (the "MERGER") of which Petrocon will be
the surviving corporation and as a result of which Petrocon will become a wholly
owned subsidiary of OEI; and

        WHEREAS the Company is entering into similar merger transactions with
W-Industries, Inc., a Texas corporation, Chemical & Industrial Engineering,
Inc., a Kentucky corporation, Gulsby Engineering, Inc., a Texas corporation and
Paulus Sokolowski and Sartor, Inc., a New Jersey corporation (collectively,
these corporations and Petrocon are the "Acquired Companies")

        WHEREAS, the Executive has been serving as an officer and director of
Petrocon, and has contributed substantially to Petrocon's growth and success;
and

        WHEREAS, OEI wishes to insure that the Company and the Acquired
Companies will have the continued benefit of the Executive's knowledge and
experience concerning the affairs of the Company, the Acquired Companies and the
engineering services industry generally, and to keep them from being availed of
by third parties, and has therefore required as a condition to its execution of
the Acquisition Agreement that the Executive enter into this Agreement to become
effective upon consummation of the Merger; and

        WHEREAS, the Executive is willing to accept employment by the Company on
the terms and conditions of this Agreement;

        NOW, THEREFORE, the Company and the Executive agree as follows:

        1.     EMPLOYMENT, DUTIES AND ACCEPTANCE.

               1.1 EMPLOYMENT BY THE COMPANY. The Company agrees to employ the
Executive as Chairman and Chief Executive Officer of the Company for the
duration of the Employment Term (as defined in Section 2 below), to render such
services and to perform such duties as are normally associated with and inherent
in the executive capacity in which the Executive will be serving, as well as
such other duties, which are not inconsistent with the Executive's position as
an executive of the Company, as shall from time to time reasonably be

<PAGE>
assigned to him by the Board of Directors of the Company (the "BOARD OF
DIRECTORS") or the officers of the Company senior to the Executive.

               1.2 ACCEPTANCE OF EMPLOYMENT BY THE EXECUTIVE. The Executive
accepts such employment for the Employment Term and agrees to render the
services required of him under Section 1.1. During the Employment Term, the
Executive shall devote his full business time, attention and energy to the
business of the Company and the performance of his duties under this Agreement.
The foregoing shall not, however, prohibit the Executive from making and
managing personal investments, or from engaging in civic or charitable
activities, that do not materially impair the performance of his duties under
this Agreement. If appointed or elected, as applicable, the Executive also shall
serve during all or any part of the Employment Term as any other officer and/or
as a director of the Company or any of its subsidiaries or affiliates, without
any additional compensation other than that specified in this Agreement.

               1.3 PLACE OF PERFORMANCE. The Executive shall be based in the
Houston/Beaumont, and nothing in this Agreement shall require the Executive to
relocate his base of employment or principal place of residence from the

               1.4 TERMINATION OF EXISTING CONTRACTS. The Executive agrees that
all agreements and contracts, whether written or oral, relating to the
employment of the Executive by the Company shall be terminated effective as of
the commencement of the Employment Term. However, nothing in this Section 1.4

extent such accruals were reflected in the Acquired Company's financial
statements delivered to OEI pursuant to the Acquisition Agreement), (ii) require
the Acquired Company to cease to make available to the Executive, and, subject
to his meeting all applicable eligibility requirements, the Executive shall be
entitled to continue to be covered under, all group health, medical and dental
insurance policies, plans and programs maintained by the Company for its
employees generally, in each case until replacement coverage is provided by the
Company, or (iii) impair or adversely affect any indemnification rights that
Executive may have under statutes empowering corporations in the Acquired
Company's state of incorporation to indemnify their officers and directors, or
under the Acquired Company's bylaws or any written indemnification agreement
between the Executive and the Acquired Company implementing such statutory
indemnification rights, but only with respect to third-party claims or
proceedings that relate to actions taken by the Executive as an officer or
director of the Acquired Company prior to the date hereof and that are disclosed
to OEI in the Disclosure Statement delivered to OEI pursuant to the Acquisition
Agreement or, if asserted or brought for the first time after the date hereof,
would not constitute a breach of the representations or warranties of the
Acquired Company or its stockholders under the Acquisition Agreement.

        2. EMPLOYMENT TERM. The term of the Executive's employment under this
Agreement (the "EMPLOYMENT TERM") shall commence on the date of consummation of
the Merger pursuant to the Acquisition Agreement (the "COMMENCEMENT DATE"), and
shall continue through and expire on the third anniversary of the Commencement
Date (the "EXPIRATION DATE"), unless earlier terminated as herein provided.
However, if the Acquisition Agreement is terminated under the terms of its
Article XII, then this Agreement shall also terminate, automatically and without
the requirement of any action on the part of either of its parties.

                      (iii) if after the Employment Term the Executive's
               employment terminates for any reason, the latest to occur of (a)
               the fourth anniversary of the Commencement Date if he is not
               eligible for severance benefits under Section 5.5 or (b) the
               expiration of the Severance Benefit Period if the Executive is

        including, without limitation, "know-how," trade secrets, customer

        shall the Executive exploit for his own benefit, or the benefit of
        others, personal relationships with customers, suppliers or agents of
        the Company in connection with or adversely affecting the Business
        formed previously during the course of his association with the Acquired
        Company or formed during the Restricted Period.

                      4.1.3 PROPERTY OF THE COMPANY. All memoranda, notes,
        lists, records and other documents or papers (and all copies thereof),
        including such items stored in computer memories, on microfiche or by
        any other means, made or compiled by or on behalf of the Executive, or
        made available to the Executive relating to the Company, other than
        purely personal matters, are and shall be the Company's property and
        shall be delivered to the Company promptly upon the termination of the
        Executive's employment (whether such termination is for Cause, as

        the Company.

                      4.1.4 EMPLOYEES OF THE COMPANY. During the Restricted
        Period and thereafter for as long as the Executive shall remain an
        employee of or consultant to the Company, the Executive shall not,
        directly or indirectly, hire or solicit any employee or consultant
        engineer of the Company away from the Company or encourage any such
        employee or agent to leave such employment.

                      4.1.5 CONSULTANTS OF THE COMPANY. During the Restricted

                      4.1.6 ACQUISITION CANDIDATES. During the Restricted Period
        and thereafter for as long as the Executive shall remain an employee of
        or consultant to the Company, the Executive shall not call on any
        Acquisition Candidate (as defined below in this Section 4.1.6), with the
        knowledge of such Acquisition Candidate's status as such, for the
        purpose of acquiring, or arranging the acquisition of, that Acquisition
        Candidate by any person or entity other than the Company. In this
        Section 4.1.6 "ACQUISITION CANDIDATE" means any person or entity engaged
        in any of the businesses of providing professional engineering services,
        and (i) which was called on by the Company, in connection with the
        possible acquisition by the Company of that person or entity, or (ii)
        with respect to which the Company has made an acquisition analysis.

               4.2 RIGHTS AND REMEDIES UPON BREACH. If the Executive breaches or
threatens to commit a breach of the Restrictive Covenants, the Company shall
have the following rights and remedies, each of which shall be independent of
the others and severally enforceable, and each of which is in addition to, and
not in lieu of, any other rights and remedies available to the Company under law
or in equity:

                      4.2.1 SPECIFIC PERFORMANCE. The right and remedy to have
        the Restrictive Covenants specifically enforced by any court of
        competent jurisdiction, it being agreed that any breach or threatened
        breach of the Restrictive Covenants would cause irreparable injury to
        the Company and that money damages would not provide an adequate remedy
        to the Company.

                      4.2.2 ACCOUNTING. The right and remedy to require the
        Executive to account for and pay over to the Company all compensation,
        profits, monies, accruals, increments or other benefits derived or
        received by the Executive as the result of any transaction constituting
        a breach of the Restrictive Covenants.

               4.3 SEVERABILITY OF COVENANTS. The Executive acknowledges and
agrees that the Restrictive Covenants are reasonable and valid in geographical
and temporal scope and in all other respects. If any court determines that any
of the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect, without regard to the invalid portions.

               4.4 REFORMATION. If any court determines that any Restrictive
Covenant, or any part thereof, is unenforceable because of the duration or
geographic scope of such provision, such court shall have the power to reduce
the duration or scope of such provision, as the case may be, and, in its reduced
form, such provision shall then be enforceable.

               4.5 ENFORCEABILITY IN JURISDICTIONS. The Company and the
Executive intend to and hereby confer jurisdiction to enforce the Restrictive
Covenants upon the courts of any jurisdiction within the geographical scope of
the Restrictive Covenants. If the courts of any one or more of such
jurisdictions hold the Restrictive Covenants unenforceable by reason of the
breadth of such scope or otherwise, it is the intention of the Company and the
Executive that such determination not bar or in any way affect the Company's
right to the relief provided above in the courts of any other jurisdiction
within the geographical scope of the Restrictive Covenants,

                                              6

<PAGE>
 as to breaches of such covenants in such other respective jurisdictions, such
covenants as they relate to each jurisdiction being, for this purpose, severable
into diverse and independent covenants.

        5.     TERMINATION.

               5.1 TERMINATION UPON DEATH. If the Executive dies during the
Employment Term, this Agreement shall terminate, except that the Executive's
legal representatives, successors, heirs or assigns shall be entitled to receive
the Annual Salary, the Additional Compensation and other accrued benefits, if
any, earned up to the date of the Executive's death; PROVIDED, HOWEVER, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company, any written agreement
contemplated thereunder or any other separate written agreement entered into
between the Executive and the Company, the terms and conditions of such plan,
policy or agreement shall control in the event of any discrepancy or conflict
with the provisions of this Agreement regarding such Additional Compensation or
other benefit upon the death, termination or disability of the Executive.

               5.2 TERMINATION FOR CAUSE. At any time during the Employment
Term, the Company shall have the right, exercisable by serving notice effective
in accordance with its terms, to terminate the Executive's employment under this
Agreement and discharge the Executive for Cause. If such right is exercised, the
Company's obligation to the Executive shall be limited to the payment of any
unpaid Annual Salary, Additional Compensation and other benefits, if any,
accrued up to the effective date specified in the Company's notice of
termination (which date shall not be retroactive). As used in this Section 5.2
and elsewhere in this Agreement, term "CAUSE" shall mean that a majority of the
Board of Directors shall have determined, and a majority of the Board of
Directors of OEI shall have concurred, that (i) after notice and a right to
cure, there has been a material breach by the Executive of the terms of this
Agreement, (ii) after receipt of a written warning, the Executive has willfully
and persistently failed or refused to follow the reasonable policies and
directives established by the Board of Directors or executive officers of the
Company senior to the Executive, (iii) the Executive has wrongfully
misappropriated money or other assets or properties of the Company or any
subsidiary or affiliate of the Company, (iv) the Executive has been convicted of
any felony or other serious crime, (v) the Executive's employment performance
has been substantially impaired by chronic absenteeism, alcoholism or drug
addiction, or (vi) the Executive has exhibited gross moral turpitude relevant to
his office or employment with the Company or any subsidiary or affiliate of the
Company.

               5.3 TERMINATION WITHOUT CAUSE. At any time during the period
beginning on the first anniversary of the Commencement Date and continuing
through the end of the Employment Term, the Company shall have the right,
exercisable by serving notice effective in accordance with its terms, to
terminate the Executive's employment under this Agreement and discharge the
Executive without Cause. If such right is exercised, the Company's obligation to
the Executive shall be as set forth in Section 5.5 below.

               5.4 TERMINATION UPON DISABILITY. If during the Employment Term
the Executive becomes physically or mentally disabled, whether totally or
partially, as evidenced by the written statement of a competent physician
licensed to practice medicine in the United States,

                                       7
<PAGE>
so that the Executive is unable to substantially perform his services hereunder
for (i) a period of six consecutive months, or (ii) for shorter periods
aggregating six months during any period of twelve consecutive months, the
Company may at any time after the last day of the six consecutive months of
disability or the day on which the shorter periods of disability equal an
aggregate of six months within a period of twelve consecutive months, by written
notice to the Executive, terminate the Executive's employment hereunder. If such
right is exercised, the Company's obligation to the Executive shall be as set
forth in Section 5.5 below.

               5.5 SEVERANCE BENEFIT. If at any time during or after the
Employment Term, the Executive's employment by the Company is terminated for any
reason other than (i) a termination for Cause under Section 5.2, (ii) his
voluntary resignation, or (iii) his death, then for a period of one year
following the date of termination of the Executive's employment (the "INITIAL
SEVERANCE BENEFIT PERIOD"), the Company shall continue to (a) pay to the
Executive, in payroll period installments in accordance with the Company's
normal payroll policies, the amount of Annual Salary in effect at the date of
termination of his employment and (b) at the Company's expense, continue to
include the Executive and his eligible dependents under the coverage of all
group health, medical and dental insurance policies, plans and programs
maintained by the Company during Initial Severance Benefit Period for the
Company's employees, or management employees, generally.

        The Company, at its option, which shall be exercisable by a written
notice sent to the Executive at least 60 days prior to the expiration of the
Initial Severance Benefit Period, may elect to extend the Initial Severance
Benefit Period for a period of an additional one year following the expiration
of the Initial Severance Benefit Period (the "SECOND SEVERANCE BENEFIT PERIOD").
If the Company so elects to extend the Initial Severance Benefit Period, the
Company, during the Second Severance Benefits Period, shall (i) pay to the
Executive, in payroll period installments in accordance with the Company's
normal payroll policies, an amount equal to 50% of the Annual Salary in effect
at the date of termination of his employment and (ii) at the Company's expense,
continue to include the Executive and his eligible dependants under the coverage
of all group health, medical and dental insurance policies, plans and programs
maintained by the Company during the Second Severance Benefit Period for the
Company's employees, or management employees, generally.

        For purposes of Section 4.1.1 of this Agreement, the term "TOTAL
SEVERANCE BENEFIT PERIOD" means the total period (including the Initial
Severance Benefit Period and, if applicable, the Second Severance Benefit
Period) during which the Company is obligated to pay and provide, and performs
its obligations to pay and provide, severance benefits to the Executive under
this Section 5.5

        6. INSURANCE. The Company may, from time to time, apply for and take
out, in its own name and at its own expense, naming itself or others as the
designated beneficiary (which it may change from time to time), policies for
health, accident, disability or other insurance upon the Executive or his life,
in any amount or amounts that it may deem necessary or appropriate to protect
its interest. The Executive agrees to aid the Company in procuring such
insurance by submitting to reasonable medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance

                                       8
<PAGE>
company or companies to which any application or applications for insurance may
be made by or for the Company.

<PAGE>
                              EMPLOYMENT AGREEMENT

        THIS AGREEMENT dated as of April 10, 1998, between OEI International,
Inc., a Delaware, corporation (the "COMPANY"), and Gary J. Coury, a resident of
League City, Texas the ("EXECUTIVE"),

                              W I T N E S S E T H:

        WHEREAS, on the date of this Agreement, the Company, Petrocon
Engineering, Inc. ("PETROCON"), PEI Acquisition, Inc., a Texas corporation and a
wholly owned subsidiary of OEI (the "MERGER SUBSIDIARY"), and the stockholders
of Petrocon, including the Executive, are entering into an Agreement and Plan of
Reorganization (the "ACQUISITION AGREEMENT"), under which Petrocon will merge
with the Merger Subsidiary in a merger (the "MERGER") of which Petrocon will be
the surviving corporation and as a result of which Petrocon will become a wholly
owned subsidiary of OEI; and

        WHEREAS the Company is entering into similar merger transactions with
W-Industries, Inc., a Texas corporation, Chemical & Industrial Engineering,
Inc., a Kentucky corporation, Gulsby Engineering, Inc., a Texas corporation and
Paulus Sokolowski and Sartor, Inc., a New Jersey corporation (collectively,
these corporations and Petrocon are the "Acquired Companies")

        WHEREAS, the Executive has been serving as an officer and director of
Petrocon, and has contributed substantially to Petrocon's growth and success;
and

        WHEREAS, OEI wishes to insure that the Company and the Acquired
Companies will have the continued benefit of the Executive's knowledge and
experience concerning the affairs of the Company, the Acquired Companies and the
engineering services industry generally, and to keep them from being availed of
by third parties, and has therefore required as a condition to its execution of
the Acquisition Agreement that the Executive enter into this Agreement to become
effective upon consummation of the Merger; and

        WHEREAS, the Executive is willing to accept employment by the Company on
the terms and conditions of this Agreement;

        NOW, THEREFORE, the Company and the Executive agree as follows:

        1.     EMPLOYMENT, DUTIES AND ACCEPTANCE.

               1.1 EMPLOYMENT BY THE COMPANY. The Company agrees to employ the
Executive as President and Chief Operating Officer of the Company for the
duration of the Employment Term (as defined in Section 2 below), to render such
services and to perform such duties as are normally associated with and inherent
in the executive capacity in which the Executive will be serving, as well as
such other duties, which are not inconsistent with the Executive's position as
an executive of the Company, as shall from time to time reasonably be


                                              1
<PAGE>
assigned to him by the Board of Directors of the Company (the "BOARD OF
DIRECTORS") or the officers of the Company senior to the Executive.

               1.2 ACCEPTANCE OF EMPLOYMENT BY THE EXECUTIVE. The Executive
accepts such employment for the Employment Term and agrees to render the
services required of him under Section 1.1. During the Employment Term, the
Executive shall devote his full business time, attention and energy to the
business of the Company and the performance of his duties under this Agreement.
The foregoing shall not, however, prohibit the Executive from making and
managing personal investments, or from engaging in civic or charitable
activities, that do not materially impair the performance of his duties under
this Agreement. If appointed or elected, as applicable, the Executive also shall
serve during all or any part of the Employment Term as any other officer and/or
as a director of the Company or any of its subsidiaries or affiliates, without
any additional compensation other than that specified in this Agreement.

               1.3 PLACE OF PERFORMANCE. The Executive shall be based in the
Houston/Beaumont, and nothing in this Agreement shall require the Executive to
relocate his base of employment or principal place of residence from the
Houston/Beaumont.

               1.4 TERMINATION OF EXISTING CONTRACTS. The Executive agrees that
all agreements and contracts, whether written or oral, relating to the
employment of the Executive by the Company shall be terminated effective as of
the commencement of the Employment Term. However, nothing in this Section 1.4
shall (i) affect accrued vacation, holiday or sick pay accruals (but only to the
extent such accruals were reflected in the Acquired Company's financial
statements delivered to OEI pursuant to the Acquisition Agreement), (ii) require
the Acquired Company to cease to make available to the Executive, and, subject
to his meeting all applicable eligibility requirements, the Executive shall be
entitled to continue to be covered under, all group health, medical and dental
insurance policies, plans and programs maintained by the Company for its
employees generally, in each case until replacement coverage is provided by the
Company, or (iii) impair or adversely affect any indemnification rights that
Executive may have under statutes empowering corporations in the Acquired
Company's state of incorporation to indemnify their officers and directors, or
under the Acquired Company's bylaws or any written indemnification agreement
between the Executive and the Acquired Company implementing such statutory
indemnification rights, but only with respect to third-party claims or
proceedings that relate to actions taken by the Executive as an officer or
director of the Acquired Company prior to the date hereof and that are disclosed
to OEI in the Disclosure Statement delivered to OEI pursuant to the Acquisition
Agreement or, if asserted or brought for the first time after the date hereof,
would not constitute a breach of the representations or warranties of the
Acquired Company or its stockholders under the Acquisition Agreement.

        2. EMPLOYMENT TERM. The term of the Executive's employment under this
Agreement (the "EMPLOYMENT TERM") shall commence on the date of consummation of
the Merger pursuant to the Acquisition Agreement (the "COMMENCEMENT DATE"), and
shall continue through and expire on the third anniversary of the Commencement
Date (the "EXPIRATION DATE"), unless earlier terminated as herein provided.
However, if the Acquisition Agreement is terminated under the terms of its
Article XII, then this Agreement shall also terminate, automatically and without
the requirement of any action on the part of either of its parties.


                                              2
<PAGE>
        3.     COMPENSATION AND OTHER BENEFITS.

               3.1 ANNUAL SALARY. As compensation for services to be rendered
under this Agreement, the Company shall pay the Executive a salary (the "ANNUAL
SALARY"), subject to such increases as the Board of Directors may, in its
discretion, approve, at a rate of $250,000 per annum. The Executive shall also
be eligible, during the Employment Term, to receive such other compensation,
whether in the form of cash bonuses, incentive compensation, stock options,
stock appreciation rights, restricted stock awards or otherwise (collectively,
the "ADDITIONAL COMPENSATION"), as the Board of Directors (or any committee of
the Board) may, in its discretion, approve. The Annual Salary and the Additional
Compensation shall be payable in accordance with the applicable payroll and/or
other compensation policies and plans of the Company as in effect from time to
time during the Employment Term, less such deductions as shall be required to be
withheld by applicable law and regulations.

               3.2 PARTICIPATION IN EMPLOYEE BENEFIT PLANS. The Executive shall
be permitted, during the Employment Term, if and to the extent he is and
continues to meet all applicable eligibility requirements, to participate in any
group life, hospitalization or disability insurance plan, health program,
pension plan, similar benefit plan or other "fringe benefits" of the Company,

        knowledge of that customer relationship; PROVIDED, HOWEVER, that nothing
        in this Section 4.1.1 shall prohibit the Executive from owning, directly
        or indirectly, solely as an investment, securities of any entity traded
        on any national securities exchange or over-the-counter market if the
        Executive is not a controlling person of, or a member of a group which
        controls, such entity and does not, directly or indirectly, own one

               employment terminates for any reason, the latest to occur of (a)
               the fourth anniversary of the Commencement Date if he is not
               eligible for severance benefits under Section 5.5

                                              4
<PAGE>
               or (b) the expiration of the Severance Benefit Period if the

        During the Restricted Period and thereafter, the Executive shall keep
        secret and retain in strict confidence, and shall not use for the

        or strategies, project development techniques or plans, business

        others, personal relationships with customers, suppliers or agents of
        the Company in connection with or adversely affecting the Business
        formed previously during the course of his association with the Acquired
        Company or formed during the Restricted Period.

                      4.1.3 PROPERTY OF THE COMPANY. All memoranda, notes,
        lists, records and other documents or papers (and all copies thereof),
        including such items stored in computer memories, on microfiche or by
        any other means, made or compiled by or on behalf of the Executive, or
        made available to the Executive relating to the Company, other than
        purely personal matters, are and shall be the Company's property and
        shall be delivered to the Company promptly upon the termination of the
        Executive's employment (whether such termination is for Cause, as
        hereinafter defined, or otherwise) or at any other time on request of
        the Company.

                      4.1.4 EMPLOYEES OF THE COMPANY. During the Restricted
        Period and thereafter for as long as the Executive shall remain an
        employee of or consultant to the Company, the Executive shall not,
        directly or indirectly, hire or solicit any employee or consultant
        engineer of the Company away from the Company or encourage any such
        employee or agent to leave such employment.

                      4.1.5 CONSULTANTS OF THE COMPANY. During the Restricted
        Period and thereafter for as long as the Executive shall remain an
        employee of or consultant to the Company, the Executive shall not,

        contract with the Company or encourage such consultant to terminate such
        relationship.

                      4.1.6 ACQUISITION CANDIDATES. During the Restricted Period
        and thereafter for as long as the Executive shall remain an employee of
        or consultant to the Company, the Executive shall not call on any
        Acquisition Candidate (as defined below in this Section 4.1.6), with the
        knowledge of such Acquisition Candidate's status as such, for the
        purpose of acquiring, or arranging the acquisition of, that Acquisition
        Candidate by any person or entity other than the Company. In this
        Section 4.1.6 "ACQUISITION CANDIDATE" means any person or entity engaged
        in any of the businesses of providing professional engineering services,
        and (i) which was called on by the Company, in


                                              5
<PAGE>
        connection with the possible acquisition by the Company of that person
        or entity, or (ii) with respect to which the Company has made an
        acquisition analysis.

               4.2 RIGHTS AND REMEDIES UPON BREACH. If the Executive breaches or
threatens to commit a breach of the Restrictive Covenants, the Company shall
have the following rights and remedies, each of which shall be independent of
the others and severally enforceable, and each of which is in addition to, and
not in lieu of, any other rights and remedies available to the Company under law
or in equity:

                      4.2.1 SPECIFIC PERFORMANCE. The right and remedy to have
        the Restrictive Covenants specifically enforced by any court of
        competent jurisdiction, it being agreed that any breach or threatened
        breach of the Restrictive Covenants would cause irreparable injury to
        the Company and that money damages would not provide an adequate remedy
        to the Company.

                      4.2.2 ACCOUNTING. The right and remedy to require the
        Executive to account for and pay over to the Company all compensation,
        profits, monies, accruals, increments or other benefits derived or
        received by the Executive as the result of any transaction constituting
        a breach of the Restrictive Covenants.

               4.3 SEVERABILITY OF COVENANTS. The Executive acknowledges and
agrees that the Restrictive Covenants are reasonable and valid in geographical
and temporal scope and in all other respects. If any court determines that any
of the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect, without regard to the invalid portions.

               4.4 REFORMATION. If any court determines that any Restrictive
Covenant, or any part thereof, is unenforceable because of the duration or
geographic scope of such provision, such court shall have the power to reduce
the duration or scope of such provision, as the case may be, and, in its reduced
form, such provision shall then be enforceable.

               4.5 ENFORCEABILITY IN JURISDICTIONS. The Company and the
Executive intend to and hereby confer jurisdiction to enforce the Restrictive
Covenants upon the courts of any jurisdiction within the geographical scope of
the Restrictive Covenants. If the courts of any one or more of such
jurisdictions hold the Restrictive Covenants unenforceable by reason of the
breadth of such scope or otherwise, it is the intention of the Company and the
Executive that such determination not bar or in any way affect the Company's
right to the relief provided above in the courts of any other jurisdiction
within the geographical scope of the Restrictive Covenants, as to breaches of
such covenants in such other respective jurisdictions, such covenants as they
relate to each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

        5.     TERMINATION.

               5.1 TERMINATION UPON DEATH. If the Executive dies during the
Employment Term, this Agreement shall terminate, except that the Executive's
legal representatives, successors, heirs or assigns shall be entitled to receive
the Annual Salary, the Additional Compensation and other accrued benefits, if
any, earned up to the date of the Executive's death; PROVIDED, HOWEVER, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company, any written agreement
contemplated thereunder or any other separate written agreement entered into
between the Executive and the Company, the terms and conditions of such plan,
policy or agreement shall control in the event of any discrepancy or conflict
with the provisions of this Agreement regarding such Additional Compensation or
other benefit upon the death, termination or disability of the Executive.

               5.2 TERMINATION FOR CAUSE. At any time during the Employment
Term, the Company shall have the right, exercisable by serving notice effective
in accordance with its terms, to terminate the Executive's employment under this
Agreement and discharge the Executive for Cause. If such right is exercised, the
Company's obligation to the Executive shall be limited to the payment of any
unpaid Annual Salary, Additional Compensation and other benefits, if any,
accrued up to the effective date specified in the Company's notice of
termination (which date shall not be retroactive). As used in this Section 5.2
and elsewhere in this Agreement, term "CAUSE" shall mean that a majority of the
Board of Directors shall have determined, and a majority of the Board of
Directors of OEI shall have concurred, that (i) after notice and a right to
cure, there has been a material breach by the Executive of the terms of this
Agreement, (ii) after receipt of a written warning, the Executive has willfully
and persistently failed or refused to follow the reasonable policies and
directives established by the Board of Directors or executive officers of the
Company senior to the Executive, (iii) the Executive has wrongfully
misappropriated money or other assets or properties of the Company or any
subsidiary or affiliate of the Company, (iv) the Executive has been convicted of
any felony or other serious crime, (v) the Executive's employment performance
has been substantially impaired by chronic absenteeism, alcoholism or drug
addiction, or (vi) the Executive has exhibited gross moral turpitude relevant to
his office or employment with the Company or any subsidiary or affiliate of the
Company.

               5.3 TERMINATION WITHOUT CAUSE. At any time during the period
beginning on the first anniversary of the Commencement Date and continuing
through the end of the Employment Term, the Company shall have the right,
exercisable by serving notice effective in accordance with its terms, to
terminate the Executive's employment under this Agreement and discharge the
Executive without Cause. If such right is exercised, the Company's obligation to
the Executive shall be as set forth in Section 5.5 below.

               5.4 TERMINATION UPON DISABILITY. If during the Employment Term
the Executive becomes physically or mentally disabled, whether totally or
partially, as evidenced by the written statement of a competent physician
licensed to practice medicine in the United States, so that the Executive is
unable to substantially perform his services hereunder for (i) a period of six
consecutive months, or (ii) for shorter periods aggregating six months during
any period of twelve consecutive months, the Company may at any time after the
last day of the six consecutive months of disability or the day on which the
shorter periods of disability equal an

                                       7
<PAGE>
aggregate of six months within a period of twelve consecutive months, by written
notice to the Executive, terminate the Executive's employment hereunder. If such
right is exercised, the Company's obligation to the Executive shall be as set
forth in Section 5.5 below.

               5.5 SEVERANCE BENEFIT. If at any time during or after the
Employment Term, the Executive's employment by the Company is terminated for any
reason other than (i) a termination for Cause under Section 5.2, (ii) his
voluntary resignation, or (iii) his death, then for a period of one year
following the date of termination of the Executive's employment (the "INITIAL
SEVERANCE BENEFIT PERIOD"), the Company shall continue to (a) pay to the
Executive, in payroll period installments in accordance with the Company's
normal payroll policies, the amount of Annual Salary in effect at the date of
termination of his employment and (b) at the Company's expense, continue to
include the Executive and his eligible dependents under the coverage of all
group health, medical and dental insurance policies, plans and programs
maintained by the Company during Initial Severance Benefit Period for the
Company's employees, or management employees, generally.

        The Company, at its option, which shall be exercisable by a written
notice sent to the Executive at least 60 days prior to the expiration of the
Initial Severance Benefit Period, may elect to extend the Initial Severance
Benefit Period for a period of an additional one year following the expiration
of the Initial Severance Benefit Period (the "SECOND SEVERANCE BENEFIT PERIOD").
If the Company so elects to extend the Initial Severance Benefit Period, the
Company, during the Second Severance Benefits Period, shall (i) pay to the
Executive, in payroll period installments in accordance with the Company's
normal payroll policies, an amount equal to 50% of the Annual Salary in effect
at the date of termination of his employment and (ii) at the Company's expense,
continue to include the Executive and his eligible dependants under the coverage
of all group health, medical and dental insurance policies, plans and programs
maintained by the Company during the Second Severance Benefit Period for the
Company's employees, or management employees, generally.

        For purposes of Section 4.1.1 of this Agreement, the term "TOTAL
SEVERANCE BENEFIT PERIOD" means the total period (including the Initial
Severance Benefit Period and, if applicable, the Second Severance Benefit
Period) during which the Company is obligated to pay and provide, and performs
its obligations to pay and provide, severance benefits to the Executive under
this Section 5.5

        6. INSURANCE. The Company may, from time to time, apply for and take
out, in its own name and at its own expense, naming itself or others as the
designated beneficiary (which it may change from time to time), policies for
health, accident, disability or other insurance upon the Executive or his life,
in any amount or amounts that it may deem necessary or appropriate to protect
its interest. The Executive agrees to aid the Company in procuring such
insurance by submitting to reasonable medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance company or companies to which any
application or applications for insurance may be made by or for the Company.

will have the benefit of the Executive's knowledge and experience concerning the
affairs of the Company, the Acquired Companies and the engineering services
industry generally, and to keep them from being availed of by third parties, and
has therefore required as a condition to its execution of the Acquisition
Agreement that the Executive enter into this Agreement to become effective upon
consummation of the Merger; and

      WHEREAS, the Executive is willing to accept employment by the Company on
the terms and conditions of this Agreement;

      NOW, THEREFORE, the Company and the Executive agree as follows:

      1.    EMPLOYMENT, DUTIES AND ACCEPTANCE.

            1.1 EMPLOYMENT BY THE COMPANY. The Company agrees to employ the
Executive as Chief Financial Officer of the Company for the duration of the
Employment Term (as defined in Section 2 below), to render such services and to
perform such duties as are normally associated with and inherent in the
executive capacity in which the Executive will be serving, as well as such other
duties, which are not inconsistent with the Executive's position as an executive
of the Company, as shall from time to time reasonably be assigned to him by the
Board of Directors of the Company (the "BOARD OF DIRECTORS") or the officers of
the Company senior to the Executive.

            1.2 ACCEPTANCE OF EMPLOYMENT BY THE EXECUTIVE. The Executive accepts
such employment for the Employment Term and agrees to render the services
required of him under Section 1.1. During the Employment Term, the Executive
shall devote his full business time, attention and energy to the business of the
Company and the performance of his duties under this Agreement. The foregoing
shall not, however, prohibit the Executive from making and managing personal
investments, or from engaging in civic or charitable activities, that do not
materially impair the performance of his duties under this Agreement. If
appointed or elected, as applicable, the Executive also shall serve during all
or any part of the Employment Term as any other officer and/or as a director of
the Company or any of its subsidiaries or affiliates, without any additional
compensation other than that specified in this Agreement.

            1.3 PLACE OF PERFORMANCE. The Executive shall be based in the
Greater Houston Metropolitan Area, and nothing in this Agreement shall require
the Executive to relocate his base of employment or principal place of residence
from the Greater Houston Metropolitan Area.

            1.4 TERMINATION OF EXISTING CONTRACTS. The Executive agrees that all
agreements and contracts, whether written or oral, relating to the employment of
the Executive by the Company shall be terminated effective as of the
commencement of the Employment Term. However, nothing in this Section 1.4 shall
(i) affect accrued vacation, holiday or sick pay accruals (but only to the
extent such accruals were reflected in the Acquired Company's financial
statements delivered to OEI pursuant to the Acquisition Agreement), (ii) require
the Acquired Company to cease to make available to the Executive, and, subject
to his meeting all applicable eligibility requirements, the Executive shall be
entitled to continue to be covered under, all group health, medical and dental
insurance policies, plans and programs maintained by the Company for its
employees generally, in each case until replacement coverage is provided by the
Company, or (iii) impair or adversely affect any indemnification rights that
Executive may have under statutes empowering corporations in the Acquired
Company's state of incorporation to indemnify their officers and directors, or
under the Acquired Company's bylaws or any written indemnification agreement
between the Executive and the Acquired Company implementing such statutory
indemnification rights, but only with respect to third-party claims or
proceedings that relate to actions taken by the Executive as an officer or
director of the Acquired Company prior to the date hereof and that are disclosed
to OEI in the Disclosure Statement delivered to OEI pursuant to the Acquisition
Agreement or, if asserted or brought for the first time after the date hereof,
would not constitute a breach of the representations or warranties of the
Acquired Company or its stockholders under the Acquisition Agreement.

      2. EMPLOYMENT TERM. The term of the Executive's employment under this
Agreement (the "EMPLOYMENT TERM") shall commence on the date of consummation of
the Merger pursuant to the Acquisition Agreement (the "COMMENCEMENT DATE"), and
shall continue through and expire on the third anniversary of the Commencement
Date (the "EXPIRATION DATE"), unless earlier terminated as herein provided.
However, if the Acquisition Agreement is terminated under the terms of its
Article XII, then this Agreement shall also terminate, automatically and without
the requirement of any action on the part of either of its parties.

      3.    COMPENSATION AND OTHER BENEFITS.

            3.1 ANNUAL SALARY. As compensation for services to be rendered under
this Agreement, the Company shall pay the Executive a salary (the "ANNUAL
SALARY"), subject to such increases as the Board of Directors may, in its
discretion, approve, at a rate of $175,000 per annum. The Executive shall also
be eligible, during the Employment Term, to receive such other compensation,
whether in the form of cash bonuses, incentive compensation, stock options,
stock appreciation rights, restricted stock awards or otherwise (collectively,
the "ADDITIONAL COMPENSATION"), as the Board of Directors (or any committee of
the Board) may, in its discretion, approve. The Annual Salary and the Additional
Compensation shall be payable in accordance with the applicable payroll and/or
other compensation policies and plans of the Company as in effect from time to
time during the Employment Term, less such deductions as shall be required to be
withheld by applicable law and regulations.

            3.2 PARTICIPATION IN EMPLOYEE BENEFIT PLANS. The Executive shall be
permitted, during the Employment Term, if and to the extent he is and continues
to meet all applicable eligibility requirements, to participate in any group
life, hospitalization or disability insurance plan, health program, pension
plan, similar benefit plan or other "fringe benefits" of the Company, which may
be available to all other similarly situated members of the Company's management
on generally the same terms.

            3.3 EXECUTIVE SUPPORT. The Company shall provide to the Executive
office facilities, furniture, and equipment, secretarial and support personnel
and other management level support services as the Executive shall reasonably
require in connection with his performance of his duties under this Agreement.

            3.4 REIMBURSEMENT OF BUSINESS EXPENSES. The Executive may incur
reasonable, ordinary and necessary business expenses in the course of his
performance of his duties under this Agreement, including expenses for travel,
food and entertainment. The Company shall reimburse the Executive for all such
business expenses if (i) the expenses are incurred by the Executive in
accordance with the Company's business expense reimbursement policy, if any, as
may be established and modified by the Company from time to time, and (ii) the
Executive provides to the Company a record of and appropriate receipts for (A)

            4.1 COVENANTS AGAINST COMPETITION. The Executive acknowledges that

      shall not (A) engage, anywhere within the Territory (as hereinafter

      business selling or providing any services which are sold or offered by
      the Company, within the territory surrounding each office or fabrication
      facility (each a "FACILITY") at which the Executive was employed by the
      Company within the three-year period immediately preceding the date of the
      Executive's termination of employment (for purposes of this Section 4.1,
      the territory surrounding a facility shall be: (1) the city, town or

      which is then sold or offered within the Territory by the Company if the
      Executive has knowledge of that customer relationship; PROVIDED, HOWEVER,
      that nothing in this Section 4.1.1 shall prohibit the Executive from
      owning, directly or indirectly, solely as an investment, securities of any
      entity traded on any national securities exchange or over-the-counter
      market if the Executive is not a controlling person of, or a member of a
      group which controls, such entity and does not, directly or indirectly,
      own one percent or more of any class of securities of such entity. As used
      in this Section 4, the term "RESTRICTED PERIOD" means the period beginning
      on the Commencement Date and ending:

                  (i) if during the Employment Term the Executive's employment
            terminates as a result of (a) a termination for Cause under Section
            5.2 or (b) the Executive's voluntary resignation, the fourth
            anniversary of the Commencement Date;

                  (ii) if during the Employment Term the Executive's employment

            severance benefits under Section 5.5

                                      4
<PAGE>
            or (b) the expiration of the Severance Benefit Period if the
            Executive is eligible for severance benefits under Section 5.5.

                  4.1.2 CONFIDENTIAL INFORMATION; PERSONAL RELATIONSHIPS. During
      the Restricted Period and thereafter, the Executive shall keep secret and
      retain in strict confidence, and shall not use for the benefit of himself
      or others, all confidential matters of the Company, including, without
      limitation, "know-how," trade secrets, customer lists, details of client
      or consultant contracts, pricing policies, bidding practices and
      procedures, operational methods, marketing plans or strategies, project
      development techniques or plans, business acquisition plans, new personnel
      acquisition plans, methods of production, manufacture and installation,
      technical processes, designs and design projects, inventions and research
      projects of the Company learned by the Executive heretofore or during the
      Restricted Period; nor shall the Executive exploit for his own benefit, or
      the benefit of others, personal relationships with customers, suppliers or
      agents of the Company in connection with or adversely affecting the
      Business formed previously during the course of his association with the
      Acquired Company or formed during the Restricted Period.

                  4.1.3 PROPERTY OF THE COMPANY. All memoranda, notes, lists,
      records and other documents or papers (and all copies thereof), including
      such items stored in computer memories, on microfiche or by any other
      means, made or compiled by or on behalf of the Executive, or made
      available to the Executive relating to the Company, other than purely
      personal matters, are and shall be the Company's property and shall be
      delivered to the Company promptly upon the termination of the Executive's
      employment (whether such termination is for Cause, as hereinafter defined,
      or otherwise) or at any other time on request of the Company.

                  4.1.4 EMPLOYEES OF THE COMPANY. During the Restricted Period
      and thereafter for as long as the Executive shall remain an employee of or
      consultant to the Company, the Executive shall not, directly or
      indirectly, hire or solicit any employee or consultant engineer of the
      Company away from the Company or encourage any such employee or agent to
      leave such employment.

                  4.1.5 CONSULTANTS OF THE COMPANY. During the Restricted Period
      and thereafter for as long as the Executive shall remain an employee of or
      consultant to the Company, the Executive shall not, directly or
      indirectly, hire or solicit any consultant then under contract with the
      Company or encourage such consultant to terminate such relationship.

                  4.1.6 ACQUISITION CANDIDATES. During the Restricted Period and
      thereafter for as long as the Executive shall remain an employee of or
      consultant to the Company, the Executive shall not call on any Acquisition
      Candidate (as defined below in this Section 4.1.6), with the knowledge of
      such Acquisition Candidate's status as such, for the purpose of acquiring,
      or arranging the acquisition of, that Acquisition Candidate by any person
      or entity other than the Company. In this Section 4.1.6 "ACQUISITION
      CANDIDATE" means any person or entity engaged in any of the businesses of
      providing professional engineering services, and (i) which was called on
      by the Company, in

                                      5
<PAGE>
      connection with the possible acquisition by the Company of that person or
      entity, or (ii) with respect to which the Company has made an acquisition
      analysis.

            4.2 RIGHTS AND REMEDIES UPON BREACH. If the Executive breaches or
threatens to commit a breach of the Restrictive Covenants, the Company shall
have the following rights and remedies, each of which shall be independent of
the others and severally enforceable, and each of which is in addition to, and
not in lieu of, any other rights and remedies available to the Company under law
or in equity:

                  4.2.1 SPECIFIC PERFORMANCE. The right and remedy to have the
      Restrictive Covenants specifically enforced by any court of competent
      jurisdiction, it being agreed that any breach or threatened breach of the
      Restrictive Covenants would cause irreparable injury to the Company and
      that money damages would not provide an adequate remedy to the Company.

                  4.2.2 ACCOUNTING. The right and remedy to require the
      Executive to account for and pay over to the Company all compensation,
      profits, monies, accruals, increments or other benefits derived or
      received by the Executive as the result of any transaction constituting a
      breach of the Restrictive Covenants.

            4.3 SEVERABILITY OF COVENANTS. The Executive acknowledges and agrees
that the Restrictive Covenants are reasonable and valid in geographical and
temporal scope and in all other respects. If any court determines that any of
the Restrictive Covenants, or any part thereof, is invalid or unenforceable, the
remainder of the Restrictive Covenants shall not thereby be affected and shall
be given full effect, without regard to the invalid portions.

            4.4 REFORMATION. If any court determines that any Restrictive
Covenant, or any part thereof, is unenforceable because of the duration or
geographic scope of such provision, such court shall have the power to reduce
the duration or scope of such provision, as the case may be, and, in its reduced
form, such provision shall then be enforceable.

            4.5 ENFORCEABILITY IN JURISDICTIONS. The Company and the Executive
intend to and hereby confer jurisdiction to enforce the Restrictive Covenants
upon the courts of any jurisdiction within the geographical scope of the
Restrictive Covenants. If the courts of any one or more of such jurisdictions
hold the Restrictive Covenants unenforceable by reason of the breadth of such
scope or otherwise, it is the intention of the Company and the Executive that
such determination not bar or in any way affect the Company's right to the
relief provided above in the courts of any other jurisdiction within the
geographical scope of the Restrictive Covenants, as to breaches of such
covenants in such other respective jurisdictions, such covenants as they relate
to each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

      5.    TERMINATION.

            5.1 TERMINATION UPON DEATH. If the Executive dies during the
Employment Term, this Agreement shall terminate, except that the Executive's
legal representatives, successors, heirs or assigns shall be entitled to receive
the Annual Salary, the Additional Compensation and other accrued benefits, if
any, earned up to the date of the Executive's death; PROVIDED, HOWEVER, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company, any written agreement
contemplated thereunder or any other separate written agreement entered into
between the Executive and the Company, the terms and conditions of such plan,
policy or agreement shall control in the event of any discrepancy or conflict
with the provisions of this Agreement regarding such Additional Compensation or
other benefit upon the death, termination or disability of the Executive.

            5.2 TERMINATION FOR CAUSE. At any time during the Employment Term,
the Company shall have the right, exercisable by serving notice effective in
accordance with its terms, to terminate the Executive's employment under this
Agreement and discharge the Executive for Cause. If such right is exercised, the
Company's obligation to the Executive shall be limited to the payment of any
unpaid Annual Salary, Additional Compensation and other benefits, if any,
accrued up to the effective date specified in the Company's notice of
termination (which date shall not be retroactive). As used in this Section 5.2
and elsewhere in this Agreement, term "CAUSE" shall mean that a majority of the
Board of Directors shall have determined, and a majority of the Board of
Directors of OEI shall have concurred, that (i) after notice and a right to
cure, there has been a material breach by the Executive of the terms of this
Agreement, (ii) after receipt of a written warning, the Executive has willfully
and persistently failed or refused to follow the reasonable policies and
directives established by the Board of Directors or executive officers of the
Company senior to the Executive, (iii) the Executive has wrongfully
misappropriated money or other assets or properties of the Company or any
subsidiary or affiliate of the Company, (iv) the Executive has been convicted of
any felony or other serious crime, (v) the Executive's employment performance
has been substantially impaired by chronic absenteeism, alcoholism or drug
addiction, or (vi) the Executive has exhibited gross moral turpitude relevant to
his office or employment with the Company or any subsidiary or affiliate of the
Company.

            5.3 TERMINATION WITHOUT CAUSE. At any time during the period
beginning on the first anniversary of the Commencement Date and continuing
through the end of the Employment Term, the Company shall have the right,
exercisable by serving notice effective in accordance with its terms, to
terminate the Executive's employment under this Agreement and discharge the
Executive without Cause. If such right is exercised, the Company's obligation to
the Executive shall be as set forth in Section 5.5 below.

            5.4 TERMINATION UPON DISABILITY. If during the Employment Term the
Executive becomes physically or mentally disabled, whether totally or partially,
as evidenced by the written statement of a competent physician licensed to
practice medicine in the United States, so that the Executive is unable to
substantially perform his services hereunder for (i) a period of six consecutive
months, or (ii) for shorter periods aggregating six months during any period of
twelve consecutive months, the Company may at any time after the last day of the
six consecutive months of disability or the day on which the shorter periods of
disability equal an

                                       7
<PAGE>
aggregate of six months within a period of twelve consecutive months, by written
notice to the Executive, terminate the Executive's employment hereunder. If such
right is exercised, the Company's obligation to the Executive shall be as set
forth in Section 5.5 below.

            5.5 SEVERANCE BENEFIT. If at any time during or after the Employment
Term, the Executive's employment by the Company is terminated for any reason
other than (i) a termination for Cause under Section 5.2, (ii) his voluntary
resignation, or (iii) his death, then for a period of one year following the
date of termination of the Executive's employment (the "INITIAL SEVERANCE
BENEFIT PERIOD"), the Company shall continue to (a) pay to the Executive, in
payroll period installments in accordance with the Company's normal payroll
policies, the amount of Annual Salary in effect at the date of termination of
his employment and (b) at the Company's expense, continue to include the
Executive and his eligible dependents under the coverage of all group health,
medical and dental insurance policies, plans and programs maintained by the
Company during Initial Severance Benefit Period for the Company's employees, or
management employees, generally.

      The Company, at its option, which shall be exercisable by a written notice
sent to the Executive at least 60 days prior to the expiration of the Initial
Severance Benefit Period, may elect to extend the Initial Severance Benefit
Period for a period of an additional one year following the expiration of the
Initial Severance Benefit Period (the "SECOND SEVERANCE BENEFIT PERIOD"). If the
Company so elects to extend the Initial Severance Benefit Period, the Company,
during the Second Severance Benefits Period, shall (i) pay to the Executive, in
payroll period installments in accordance with the Company's normal payroll
policies, an amount equal to 50% of the Annual Salary in effect at the date of
termination of his employment and (ii) at the Company's expense, continue to
include the Executive and his eligible dependants under the coverage of all
group health, medical and dental insurance policies, plans and programs
maintained by the Company during the Second Severance Benefit Period for the
Company's employees, or management employees, generally.

      For purposes of Section 4.1.1 of this Agreement, the term "TOTAL SEVERANCE
BENEFIT PERIOD" means the total period (including the Initial Severance Benefit
Period and, if applicable, the Second Severance Benefit Period) during which the
Company is obligated to pay and provide, and performs its obligations to pay and
provide, severance benefits to the Executive under this Section 5.5

      6. INSURANCE. The Company may, from time to time, apply for and take out,
in its own name and at its own expense, naming itself or others as the
designated beneficiary (which it may change from time to time), policies for
health, accident, disability or other insurance upon the Executive or his life,
in any amount or amounts that it may deem necessary or appropriate to protect
its interest. The Executive agrees to aid the Company in procuring such
insurance by submitting to reasonable medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance company or companies to which any
application or applications for insurance may be made by or for the Company.

                                     EMPLOYMENT AGREEMENT

        THIS AGREEMENT dated as of April 10, 1998, between OEI International,
Inc., a Delaware, corporation (the "COMPANY"), and Dana W. Swindler, a resident
of Dallas, Texas the ("EXECUTIVE"),

                                     W I T N E S S E T H:

        WHEREAS, on the date of this Agreement, the Company, Petrocon
Engineering, Inc. ("PETROCON"), PEI Acquisition, Inc., a Texas corporation and a
wholly owned subsidiary of OEI (the "MERGER SUBSIDIARY"), and the stockholders
of Petrocon, including the Executive, are entering into an Agreement and Plan of
Reorganization (the "ACQUISITION AGREEMENT"), under which Petrocon will merge
with the Merger Subsidiary in a merger (the "MERGER") of which Petrocon will be
the surviving corporation and as a result of which Petrocon will become a wholly
owned subsidiary of OEI; and

        WHEREAS the Company is entering into similar merger transactions with
W-Industries, Inc., a Texas corporation, Chemical & Industrial Engineering,
Inc., a Kentucky corporation, Gulsby Engineering, Inc., a Texas corporation and
Paulus Sokolowski and Sartor, Inc., a New Jersey corporation (collectively,
these corporations and Petrocon are the "Acquired Companies")

        WHEREAS, the Executive has been serving as an officer and director of
Petrocon, and has contributed substantially to Petrocon's growth and success;
and

        WHEREAS, OEI wishes to insure that the Company and the Acquired
Companies will have the continued benefit of the Executive's knowledge and
experience concerning the affairs of the Company, the Acquired Companies and the
engineering services industry generally, and to keep them from being availed of
by third parties, and has therefore required as a condition to its execution of
the Acquisition Agreement that the Executive enter into this Agreement to become
effective upon consummation of the Merger; and

        WHEREAS, the Executive is willing to accept employment by the Company on
the terms and conditions of this Agreement;

        NOW, THEREFORE, the Company and the Executive agree as follows:

        1.     EMPLOYMENT, DUTIES AND ACCEPTANCE.

               1.1 EMPLOYMENT BY THE COMPANY. The Company agrees to employ the
Executive as Executive Vice President-Manager of Mergers and Acquisitions of the
Company for the duration of the Employment Term (as defined in Section 2 below),
to render such services and to perform such duties as are normally associated
with and inherent in the executive capacity in which the Executive will be
serving, as well as such other duties, which are not inconsistent with the
Executive's position as an executive of the Company, as shall from time to time


                                              1
<PAGE>
reasonably be assigned to him by the Board of Directors of the Company (the
"BOARD OF DIRECTORS") or the officers of the Company senior to the Executive.

               1.2 ACCEPTANCE OF EMPLOYMENT BY THE EXECUTIVE. The Executive
accepts such employment for the Employment Term and agrees to render the
services required of him under Section 1.1. During the Employment Term, the
Executive shall devote his full business time, attention and energy to the
business of the Company and the performance of his duties under this Agreement.
The foregoing shall not, however, prohibit the Executive from making and
managing personal investments, or from engaging in civic or charitable
activities, that do not materially impair the performance of his duties under
this Agreement. If appointed or elected, as applicable, the Executive also shall
serve during all or any part of the Employment Term as any other officer and/or
as a director of the Company or any of its subsidiaries or affiliates, without
any additional compensation other than that specified in this Agreement.

               1.3 PLACE OF PERFORMANCE. The Executive shall be based in the
Dallas, and nothing in this Agreement shall require the Executive to relocate
his base of employment or principal place of residence from the Dallas.

               1.4 TERMINATION OF EXISTING CONTRACTS. The Executive agrees that
all agreements and contracts, whether written or oral, relating to the
employment of the Executive by the Company shall be terminated effective as of
the commencement of the Employment Term. However, nothing in this Section 1.4
shall (i) affect accrued vacation, holiday or sick pay accruals (but only to the
extent such accruals were reflected in the Acquired Company's financial
statements delivered to OEI pursuant to the Acquisition Agreement), (ii) require
the Acquired Company to cease to make available to the Executive, and, subject
to his meeting all applicable eligibility requirements, the Executive shall be
entitled to continue to be covered under, all group health, medical and dental
insurance policies, plans and programs maintained by the Company for its
employees generally, in each case until replacement coverage is provided by the
Company, or (iii) impair or adversely affect any indemnification rights that
Executive may have under statutes empowering corporations in the Acquired
Company's state of incorporation to indemnify their officers and directors, or
under the Acquired Company's bylaws or any written indemnification agreement
between the Executive and the Acquired Company implementing such statutory
indemnification rights, but only with respect to third-party claims or
proceedings that relate to actions taken by the Executive as an officer or
director of the Acquired Company prior to the date hereof and that are disclosed
to OEI in the Disclosure Statement delivered to OEI pursuant to the Acquisition
Agreement or, if asserted or brought for the first time after the date hereof,
would not constitute a breach of the representations or warranties of the
Acquired Company or its stockholders under the Acquisition Agreement.

        2. EMPLOYMENT TERM. The term of the Executive's employment under this
Agreement (the "EMPLOYMENT TERM") shall commence on the date of consummation of
the Merger pursuant to the Acquisition Agreement (the "COMMENCEMENT DATE"), and
shall continue through and expire on the third anniversary of the Commencement
Date (the "EXPIRATION DATE"), unless earlier terminated as herein provided.
However, if the Acquisition Agreement is terminated under the terms of its
Article XII, then this Agreement shall also terminate, automatically and without
the requirement of any action on the part of either of its parties.


                                              2

        3.     COMPENSATION AND OTHER BENEFITS.

               3.1 ANNUAL SALARY. As compensation for services to be rendered
under this Agreement, the Company shall pay the Executive a salary (the "ANNUAL
SALARY"), subject to such increases as the Board of Directors may, in its
discretion, approve, at a rate of $200,000 per annum. The Executive shall also
be eligible, during the Employment Term, to receive such other compensation,
whether in the form of cash bonuses, incentive compensation, stock options,
stock appreciation rights, restricted stock awards or otherwise (collectively,
the "ADDITIONAL COMPENSATION"), as the Board of Directors (or any committee of
the Board) may, in its discretion, approve. The Annual Salary and the Additional
Compensation shall be payable in accordance with the applicable payroll and/or
other compensation policies and plans of the Company as in effect from time to
time during the Employment Term, less such deductions as shall be required to be
withheld by applicable law and regulations.

               3.2 PARTICIPATION IN EMPLOYEE BENEFIT PLANS. The Executive shall
be permitted, during the Employment Term, if and to the extent he is and
continues to meet all applicable eligibility requirements, to participate in any
group life, hospitalization or disability insurance plan, health program,
pension plan, similar benefit plan or other "fringe benefits" of the Company,
which may be available to all other similarly situated members of the Company's
management on generally the same terms.

               3.3 EXECUTIVE SUPPORT. The Company shall provide to the Executive
office facilities, furniture, and equipment, secretarial and support personnel
and other management level support services as the Executive shall reasonably
require in connection with his performance of his duties under this Agreement.

               3.4 REIMBURSEMENT OF BUSINESS EXPENSES. The Executive may incur
reasonable, ordinary and necessary business expenses in the course of his
performance of his duties under this Agreement, including expenses for travel,
food and entertainment. The Company shall reimburse the Executive for all such
business expenses if (i) the expenses are incurred by the Executive in
accordance with the Company's business expense reimbursement policy, if any, as
may be established and modified by the Company from time to time, and (ii) the
Executive provides to the Company a record of and appropriate receipts for (A)
the amount of the expense, (B) the date, place and nature of the expense, (C)
the business reason for the expense and (D) the names, occupations and other
data concerning individuals entertained sufficient to establish their business
relationship to the Company. The Company shall have no obligation to reimburse
the Executive for expenses that are not incurred and substantiated as required
by this Section 3.4.

        4.     NON-COMPETITION.

               4.1 COVENANTS AGAINST COMPETITION. The Executive acknowledges

the Business and the goodwill of the Company; and (vi) the Restrictive Covenants
will not impair his ability to do so. Accordingly, the Executive agrees as

                      4.1.1 NON-COMPETE. During the Restricted Period, the
        Executive shall not (A) engage, anywhere within the Territory (as

        advisor, in any business selling or providing any services which are
        sold or offered by the Company, within the territory surrounding each
        office or fabrication facility (each a "FACILITY") at which the
        Executive was employed by the Company within the three-year period
        immediately preceding the date of the Executive's termination of
        employment (for purposes of this Section 4.1, the territory surrounding

        is located, (2) the county or parish in which the facility is located,
        (3) the counties or parishes contiguous to the county or parish in which
        the facility is located and (4) the area located within 100 miles of the

        Executive's employment was, a customer of the Company, for the purpose
        of soliciting or selling any product or service which is then sold or
        offered within the Territory by the Company if the Executive has
        knowledge of that customer relationship; PROVIDED, HOWEVER, that nothing
        in this Section 4.1.1 shall prohibit the Executive from owning, directly
        or indirectly, solely as an investment, securities of any entity traded
        on any national securities exchange or over-the-counter market if the
        Executive is not a controlling person of, or a member of a group which
        controls, such entity and does not, directly or indirectly, own one
        percent or more of any class of securities of such entity. As used in
        this Section 4, the term "RESTRICTED PERIOD" means the period beginning
        on the Commencement Date and ending:

               employment terminates for any reason, the latest to occur of (a)
               the fourth anniversary of the Commencement Date if he is not
               eligible for severance benefits under Section 5.5

                                              4
<PAGE>
               or (b) the expiration of the Severance Benefit Period if the
               Executive is eligible for severance benefits under Section 5.5.

                      4.1.2 CONFIDENTIAL INFORMATION; PERSONAL RELATIONSHIPS.

        including, without limitation, "know-how," trade secrets, customer

        bidding practices and procedures, operational methods, marketing plans
        or strategies, project development techniques or plans, business

        shall the Executive exploit for his own benefit, or the benefit of
        others, personal relationships with customers, suppliers or agents of
        the Company in connection with or adversely affecting the Business
        formed previously during the course of his association with the Acquired
        Company or formed during the Restricted Period.

                      4.1.3 PROPERTY OF THE COMPANY. All memoranda, notes,
        lists, records and other documents or papers (and all copies thereof),
        including such items stored in computer memories, on microfiche or by
        any other means, made or compiled by or on behalf of the Executive, or
        made available to the Executive relating to the Company, other than
        purely personal matters, are and shall be the Company's property and
        shall be delivered to the Company promptly upon the termination of the
        Executive's employment (whether such termination is for Cause, as
        hereinafter defined, or otherwise) or at any other time on request of
        the Company.

                      4.1.4 EMPLOYEES OF THE COMPANY. During the Restricted
        Period and thereafter for as long as the Executive shall remain an
        employee of or consultant to the Company, the Executive shall not,
        directly or indirectly, hire or solicit any employee or consultant
        engineer of the Company away from the Company or encourage any such
        employee or agent to leave such employment.

                      4.1.5 CONSULTANTS OF THE COMPANY. During the Restricted
        Period and thereafter for as long as the Executive shall remain an
        employee of or consultant to the Company, the Executive shall not,
        directly or indirectly, hire or solicit any consultant then under
        contract with the Company or encourage such consultant to terminate such
        relationship.

                      4.1.6 ACQUISITION CANDIDATES. During the Restricted Period
        and thereafter for as long as the Executive shall remain an employee of
        or consultant to the Company, the Executive shall not call on any
        Acquisition Candidate (as defined below in this Section 4.1.6), with the
        knowledge of such Acquisition Candidate's status as such, for the
        purpose of acquiring, or arranging the acquisition of, that Acquisition
        Candidate by any person or entity other than the Company. In this
        Section 4.1.6 "ACQUISITION CANDIDATE" means any person or entity engaged
        in any of the businesses of providing professional engineering services,
        and (i) which was called on by the Company, in

                                              5
<PAGE>
        connection with the possible acquisition by the Company of that person
        or entity, or (ii) with respect to which the Company has made an
        acquisition analysis.

               4.2 RIGHTS AND REMEDIES UPON BREACH. If the Executive breaches or
threatens to commit a breach of the Restrictive Covenants, the Company shall
have the following rights and remedies, each of which shall be independent of
the others and severally enforceable, and each of which is in addition to, and
not in lieu of, any other rights and remedies available to the Company under law
or in equity:

                      4.2.1 SPECIFIC PERFORMANCE. The right and remedy to have
        the Restrictive Covenants specifically enforced by any court of
        competent jurisdiction, it being agreed that any breach or threatened
        breach of the Restrictive Covenants would cause irreparable injury to
        the Company and that money damages would not provide an adequate remedy
        to the Company.

                      4.2.2 ACCOUNTING. The right and remedy to require the
        Executive to account for and pay over to the Company all compensation,
        profits, monies, accruals, increments or other benefits derived or
        received by the Executive as the result of any transaction constituting
        a breach of the Restrictive Covenants.

               4.3 SEVERABILITY OF COVENANTS. The Executive acknowledges and
agrees that the Restrictive Covenants are reasonable and valid in geographical
and temporal scope and in all other respects. If any court determines that any
of the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect, without regard to the invalid portions.

               4.4 REFORMATION. If any court determines that any Restrictive
Covenant, or any part thereof, is unenforceable because of the duration or
geographic scope of such provision, such court shall have the power to reduce
the duration or scope of such provision, as the case may be, and, in its reduced
form, such provision shall then be enforceable.

               4.5 ENFORCEABILITY IN JURISDICTIONS. The Company and the
Executive intend to and hereby confer jurisdiction to enforce the Restrictive
Covenants upon the courts of any jurisdiction within the geographical scope of
the Restrictive Covenants. If the courts of any one or more of such
jurisdictions hold the Restrictive Covenants unenforceable by reason of the
breadth of such scope or otherwise, it is the intention of the Company and the
Executive that such determination not bar or in any way affect the Company's
right to the relief provided above in the courts of any other jurisdiction
within the geographical scope of the Restrictive Covenants, as to breaches of
such covenants in such other respective jurisdictions, such covenants as they
relate to each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

        5.     TERMINATION.

               5.1 TERMINATION UPON DEATH. If the Executive dies during the
Employment Term, this Agreement shall terminate, except that the Executive's
legal representatives, successors, heirs or assigns shall be entitled to receive
the Annual Salary, the Additional Compensation and other accrued benefits, if
any, earned up to the date of the Executive's death; PROVIDED, HOWEVER, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company, any written agreement
contemplated thereunder or any other separate written agreement entered into
between the Executive and the Company, the terms and conditions of such plan,
policy or agreement shall control in the event of any discrepancy or conflict
with the provisions of this Agreement regarding such Additional Compensation or
other benefit upon the death, termination or disability of the Executive.

               5.2 TERMINATION FOR CAUSE. At any time during the Employment
Term, the Company shall have the right, exercisable by serving notice effective
in accordance with its terms, to terminate the Executive's employment under this
Agreement and discharge the Executive for Cause. If such right is exercised, the
Company's obligation to the Executive shall be limited to the payment of any
unpaid Annual Salary, Additional Compensation and other benefits, if any,
accrued up to the effective date specified in the Company's notice of
termination (which date shall not be retroactive). As used in this Section 5.2
and elsewhere in this Agreement, term "CAUSE" shall mean that a majority of the
Board of Directors shall have determined, and a majority of the Board of
Directors of OEI shall have concurred, that (i) after notice and a right to
cure, there has been a material breach by the Executive of the terms of this
Agreement, (ii) after receipt of a written warning, the Executive has willfully
and persistently failed or refused to follow the reasonable policies and
directives established by the Board of Directors or executive officers of the
Company senior to the Executive, (iii) the Executive has wrongfully
misappropriated money or other assets or properties of the Company or any
subsidiary or affiliate of the Company, (iv) the Executive has been convicted of
any felony or other serious crime, (v) the Executive's employment performance
has been substantially impaired by chronic absenteeism, alcoholism or drug
addiction, or (vi) the Executive has exhibited gross moral turpitude relevant to
his office or employment with the Company or any subsidiary or affiliate of the
Company.

               5.3 TERMINATION WITHOUT CAUSE. At any time during the period
beginning on the first anniversary of the Commencement Date and continuing
through the end of the Employment Term, the Company shall have the right,
exercisable by serving notice effective in accordance with its terms, to
terminate the Executive's employment under this Agreement and discharge the
Executive without Cause. If such right is exercised, the Company's obligation to
the Executive shall be as set forth in Section 5.5 below.

               5.4 TERMINATION UPON DISABILITY. If during the Employment Term
the Executive becomes physically or mentally disabled, whether totally or
partially, as evidenced by the written statement of a competent physician
licensed to practice medicine in the United States, so that the Executive is
unable to substantially perform his services hereunder for (i) a period of six
consecutive months, or (ii) for shorter periods aggregating six months during
any period of twelve consecutive months, the Company may at any time after the
last day of the six consecutive months of disability or the day on which the
shorter periods of disability equal an

<PAGE>
aggregate of six months within a period of twelve consecutive months, by written
notice to the Executive, terminate the Executive's employment hereunder. If such
right is exercised, the Company's obligation to the Executive shall be as set
forth in Section 5.5 below.

               5.5 SEVERANCE BENEFIT. If at any time during or after the
Employment Term, the Executive's employment by the Company is terminated for any
reason other than (i) a termination for Cause under Section 5.2, (ii) his
voluntary resignation, or (iii) his death, then for a period of one year
following the date of termination of the Executive's employment (the "INITIAL
SEVERANCE BENEFIT PERIOD"), the Company shall continue to (a) pay to the
Executive, in payroll period installments in accordance with the Company's
normal payroll policies, the amount of Annual Salary in effect at the date of
termination of his employment and (b) at the Company's expense, continue to
include the Executive and his eligible dependents under the coverage of all
group health, medical and dental insurance policies, plans and programs
maintained by the Company during Initial Severance Benefit Period for the
Company's employees, or management employees, generally.

        The Company, at its option, which shall be exercisable by a written
notice sent to the Executive at least 60 days prior to the expiration of the
Initial Severance Benefit Period, may elect to extend the Initial Severance
Benefit Period for a period of an additional one year following the expiration
of the Initial Severance Benefit Period (the "SECOND SEVERANCE BENEFIT PERIOD").
If the Company so elects to extend the Initial Severance Benefit Period, the
Company, during the Second Severance Benefits Period, shall (i) pay to the
Executive, in payroll period installments in accordance with the Company's

at the date of termination of his employment and (ii) at the Company's expense,
continue to include the Executive and his eligible dependants under the coverage
of all group health, medical and dental insurance policies, plans and programs
maintained by the Company during the Second Severance Benefit Period for the
Company's employees, or management employees, generally.

        For purposes of Section 4.1.1 of this Agreement, the term "TOTAL

Severance Benefit Period and, if applicable, the Second Severance Benefit

out, in its own name and at its own expense, naming itself or others as the
designated beneficiary (which it may change from time to time), policies for
health, accident, disability or other insurance upon the Executive or his life,
in any amount or amounts that it may deem necessary or appropriate to protect
its interest. The Executive agrees to aid the Company in procuring such
insurance by submitting to reasonable medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance company or companies to which any
application or applications for insurance may be made by or for the Company.

                                     EMPLOYMENT AGREEMENT

        THIS AGREEMENT dated as of April 10, 1998, between OEI International,
Inc., a Delaware, corporation (the "COMPANY"), and Robert W. Raiford, a resident
of Houston, Texas the ("EXECUTIVE"),

                                     W I T N E S S E T H:

        WHEREAS, on the date of this Agreement, the Company, Petrocon
Engineering, Inc. ("PETROCON"), PEI Acquisition, Inc., a Texas corporation and a
wholly owned subsidiary of OEI (the "MERGER SUBSIDIARY"), and the stockholders
of Petrocon, including the Executive, are entering into an Agreement and Plan of
Reorganization (the "ACQUISITION AGREEMENT"), under which Petrocon will merge
with the Merger Subsidiary in a merger (the "MERGER") of which Petrocon will be
the surviving corporation and as a result of which Petrocon will become a wholly
owned subsidiary of OEI; and

        WHEREAS the Company is entering into similar merger transactions with
W-Industries, Inc., a Texas corporation, Chemical & Industrial Engineering,
Inc., a Kentucky corporation, Gulsby Engineering, Inc., a Texas corporation and
Paulus Sokolowski and Sartor, Inc., a New Jersey corporation (collectively,
these corporations and Petrocon are the "Acquired Companies")

        WHEREAS, the Executive has been serving as an officer and director of
Petrocon, and has contributed substantially to Petrocon's growth and success;
and

        WHEREAS, OEI wishes to insure that the Company and the Acquired
Companies will have the continued benefit of the Executive's knowledge and
experience concerning the affairs of the Company, the Acquired Companies and the
engineering services industry generally, and to keep them from being availed of
by third parties, and has therefore required as a condition to its execution of
the Acquisition Agreement that the Executive enter into this Agreement to become
effective upon consummation of the Merger; and

        WHEREAS, the Executive is willing to accept employment by the Company on
the terms and conditions of this Agreement;

        NOW, THEREFORE, the Company and the Executive agree as follows:

        1.     EMPLOYMENT, DUTIES AND ACCEPTANCE.

               1.1 EMPLOYMENT BY THE COMPANY. The Company agrees to employ the
Executive as Controller of the Company for the duration of the Employment Term
(as defined in Section 2 below), to render such services and to perform such
duties as are normally associated with and inherent in the executive capacity in
which the Executive will be serving, as well as such other duties, which are not
inconsistent with the Executive's position as an executive of the Company, as
shall from time to time reasonably be assigned to him by the Board of Directors
of the Company (the "BOARD OF DIRECTORS") or the officers of the Company senior
to the Executive.

                                              1
<PAGE>
               1.2 ACCEPTANCE OF EMPLOYMENT BY THE EXECUTIVE. The Executive
accepts such employment for the Employment Term and agrees to render the
services required of him under Section 1.1. During the Employment Term, the
Executive shall devote his full business time, attention and energy to the
business of the Company and the performance of his duties under this Agreement.
The foregoing shall not, however, prohibit the Executive from making and
managing personal investments, or from engaging in civic or charitable
activities, that do not materially impair the performance of his duties under
this Agreement. If appointed or elected, as applicable, the Executive also shall
serve during all or any part of the Employment Term as any other officer and/or
as a director of the Company or any of its subsidiaries or affiliates, without
any additional compensation other than that specified in this Agreement.

               1.3 PLACE OF PERFORMANCE. The Executive shall be based in the
Houston/Beaumont Metropolitan Area, and nothing in this Agreement shall require
the Executive to relocate his base of employment or principal place of residence
from the Houston/Beaumont Metropolitan Area.

               1.4 TERMINATION OF EXISTING CONTRACTS. The Executive agrees that
all agreements and contracts, whether written or oral, relating to the
employment of the Executive by the Company shall be terminated effective as of
the commencement of the Employment Term. However, nothing in this Section 1.4
shall (i) affect accrued vacation, holiday or sick pay accruals (but only to the
extent such accruals were reflected in the Acquired Company's financial
statements delivered to OEI pursuant to the Acquisition Agreement), (ii) require
the Acquired Company to cease to make available to the Executive, and, subject
to his meeting all applicable eligibility requirements, the Executive shall be
entitled to continue to be covered under, all group health, medical and dental
insurance policies, plans and programs maintained by the Company for its
employees generally, in each case until replacement coverage is provided by the
Company, or (iii) impair or adversely affect any indemnification rights that
Executive may have under statutes empowering corporations in the Acquired
Company's state of incorporation to indemnify their officers and directors, or
under the Acquired Company's bylaws or any written indemnification agreement
between the Executive and the Acquired Company implementing such statutory
indemnification rights, but only with respect to third-party claims or
proceedings that relate to actions taken by the Executive as an officer or
director of the Acquired Company prior to the date hereof and that are disclosed
to OEI in the Disclosure Statement delivered to OEI pursuant to the Acquisition
Agreement or, if asserted or brought for the first time after the date hereof,
would not constitute a breach of the representations or warranties of the
Acquired Company or its stockholders under the Acquisition Agreement.

        2. EMPLOYMENT TERM. The term of the Executive's employment under this
Agreement (the "EMPLOYMENT TERM") shall commence on the date of consummation of
the Merger pursuant to the Acquisition Agreement (the "COMMENCEMENT DATE"), and
shall continue through and expire on the third anniversary of the Commencement
Date (the "EXPIRATION DATE"), unless earlier terminated as herein provided.
However, if the Acquisition Agreement is terminated under the terms of its
Article XII, then this Agreement shall also terminate, automatically and without
the requirement of any action on the part of either of its parties.

under this Agreement, the Company shall pay the Executive a salary (the "ANNUAL
SALARY"), subject to such increases as the Board of Directors may, in its
discretion, approve, at a rate of $162,000 per annum. The Executive shall also
be eligible, during the Employment Term, to receive such other compensation,
whether in the form of cash bonuses, incentive compensation, stock options,
stock appreciation rights, restricted stock awards or otherwise (collectively,
the "ADDITIONAL COMPENSATION"), as the Board of Directors (or any committee of
the Board) may, in its discretion, approve. The Annual Salary and the Additional
Compensation shall be payable in accordance with the applicable payroll and/or
other compensation policies and plans of the Company as in effect from time to
time during the Employment Term, less such deductions as shall be required to be
withheld by applicable law and regulations.

               3.2 PARTICIPATION IN EMPLOYEE BENEFIT PLANS. The Executive shall
be permitted, during the Employment Term, if and to the extent he is and
continues to meet all applicable eligibility requirements, to participate in any
group life, hospitalization or disability insurance plan, health program,
pension plan, similar benefit plan or other "fringe benefits" of the Company,
which may be available to all other similarly situated members of the Company's
management on generally the same terms.

               3.3 EXECUTIVE SUPPORT. The Company shall provide to the Executive
office facilities, furniture, and equipment, secretarial and support personnel
and other management level support services as the Executive shall reasonably
require in connection with his performance of his duties under this Agreement.

               3.4 REIMBURSEMENT OF BUSINESS EXPENSES. The Executive may incur
reasonable, ordinary and necessary business expenses in the course of his
performance of his duties under this Agreement, including expenses for travel,
food and entertainment. The Company shall reimburse the Executive for all such
business expenses if (i) the expenses are incurred by the Executive in
accordance with the Company's business expense reimbursement policy, if any, as
may be established and modified by the Company from time to time, and (ii) the
Executive provides to the Company a record of and appropriate receipts for (A)
the amount of the expense, (B) the date, place and nature of the expense, (C)
the business reason for the expense and (D) the names, occupations and other
data concerning individuals entertained sufficient to establish their business
relationship to the Company. The Company shall have no obligation to reimburse
the Executive for expenses that are not incurred and substantiated as required
by this Section 3.4.

               3.5 AUTOMOBILE. The Company shall provide the Executive with the
use of a Company-owned or leased automobile for use by the Executive in
connection with the performance of his duties under this Agreement, and shall
pay the reasonable costs of insuring, operating and maintaining the automobile,
or, in lieu thereof the Company, at is option, may pay to the Executive an
automobile allowance to help defray the Executive's cost of owning and operating
a personal automobile for such purpose.

        Company or formed during the Restricted Period.

        lists, records and other documents or papers (and all copies thereof),
        including such items stored in computer memories, on microfiche or by
        any other means, made or compiled by or on behalf of the Executive, or
        made available to the Executive relating to the Company, other than
        purely personal matters, are and shall be the Company's property and
        shall be delivered to the Company promptly upon the termination of the
        Executive's employment (whether such termination is for Cause, as
        hereinafter defined, or otherwise) or at any other time on request of
        the Company.

                      4.1.4 EMPLOYEES OF THE COMPANY. During the Restricted
        Period and thereafter for as long as the Executive shall remain an
        employee of or consultant to the Company, the Executive shall not,

        engineer of the Company away from the Company or encourage any such
        employee or agent to leave such employment.

                      4.1.6 ACQUISITION CANDIDATES. During the Restricted Period
        and thereafter for as long as the Executive shall remain an employee of
        or consultant to the Company, the Executive shall not call on any
        Acquisition Candidate (as defined below in this Section 4.1.6), with the
        knowledge of such Acquisition Candidate's status as such, for the
        purpose of acquiring, or arranging the acquisition of, that Acquisition

        the Restrictive Covenants specifically enforced by any court of
        competent jurisdiction, it being agreed that any breach or threatened
        breach of the Restrictive Covenants would cause irreparable injury to
        the Company and that money damages would not provide an adequate remedy
        to the Company.

                      4.2.2 ACCOUNTING. The right and remedy to require the
        Executive to account for and pay over to the Company all compensation,
        profits, monies, accruals, increments or other benefits derived or
        received by the Executive as the result of any transaction constituting
        a breach of the Restrictive Covenants.

               4.3 SEVERABILITY OF COVENANTS. The Executive acknowledges and
agrees that the Restrictive Covenants are reasonable and valid in geographical
and temporal scope and in all other respects. If any court determines that any
of the Restrictive Covenants, or any part thereof, is invalid or unenforceable,
the remainder of the Restrictive Covenants shall not thereby be affected and
shall be given full effect, without regard to the invalid portions.

               4.4 REFORMATION. If any court determines that any Restrictive
Covenant, or any part thereof, is unenforceable because of the duration or
geographic scope of such provision, such court shall have the power to reduce
the duration or scope of such provision, as the case may be, and, in its reduced
form, such provision shall then be enforceable.

               4.5 ENFORCEABILITY IN JURISDICTIONS. The Company and the
Executive intend to and hereby confer jurisdiction to enforce the Restrictive
Covenants upon the courts of any jurisdiction within the geographical scope of
the Restrictive Covenants. If the courts of any one or more of such
jurisdictions hold the Restrictive Covenants unenforceable by reason of the
breadth of such scope or otherwise, it is the intention of the Company and the
Executive that such determination not bar or in any way affect the Company's
right to the relief provided above in the courts of any other jurisdiction
within the geographical scope of the Restrictive Covenants,

                                              6
<PAGE>
 as to breaches of such covenants in such other respective jurisdictions, such
covenants as they relate to each jurisdiction being, for this purpose, severable
into diverse and independent covenants.

        5.     TERMINATION.

               5.1 TERMINATION UPON DEATH. If the Executive dies during the
Employment Term, this Agreement shall terminate, except that the Executive's
legal representatives, successors, heirs or assigns shall be entitled to receive
the Annual Salary, the Additional Compensation and other accrued benefits, if
any, earned up to the date of the Executive's death; PROVIDED, HOWEVER, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company, any written agreement
contemplated thereunder or any other separate written agreement entered into
between the Executive and the Company, the terms and conditions of such plan,
policy or agreement shall control in the event of any discrepancy or conflict
with the provisions of this Agreement regarding such Additional Compensation or
other benefit upon the death, termination or disability of the Executive.

               5.2 TERMINATION FOR CAUSE. At any time during the Employment
Term, the Company shall have the right, exercisable by serving notice effective
in accordance with its terms, to terminate the Executive's employment under this
Agreement and discharge the Executive for Cause. If such right is exercised, the
Company's obligation to the Executive shall be limited to the payment of any
unpaid Annual Salary, Additional Compensation and other benefits, if any,
accrued up to the effective date specified in the Company's notice of
termination (which date shall not be retroactive). As used in this Section 5.2
and elsewhere in this Agreement, term "CAUSE" shall mean that a majority of the
Board of Directors shall have determined, and a majority of the Board of
Directors of OEI shall have concurred, that (i) after notice and a right to
cure, there has been a material breach by the Executive of the terms of this
Agreement, (ii) after receipt of a written warning, the Executive has willfully
and persistently failed or refused to follow the reasonable policies and
directives established by the Board of Directors or executive officers of the
Company senior to the Executive, (iii) the Executive has wrongfully
misappropriated money or other assets or properties of the Company or any
subsidiary or affiliate of the Company, (iv) the Executive has been convicted of
any felony or other serious crime, (v) the Executive's employment performance
has been substantially impaired by chronic absenteeism, alcoholism or drug
addiction, or (vi) the Executive has exhibited gross moral turpitude relevant to
his office or employment with the Company or any subsidiary or affiliate of the
Company.

               5.3 TERMINATION WITHOUT CAUSE. At any time during the period
beginning on the first anniversary of the Commencement Date and continuing
through the end of the Employment Term, the Company shall have the right,
exercisable by serving notice effective in accordance with its terms, to
terminate the Executive's employment under this Agreement and discharge the
Executive without Cause. If such right is exercised, the Company's obligation to
the Executive shall be as set forth in Section 5.5 below.

               5.4 TERMINATION UPON DISABILITY. If during the Employment Term
the Executive becomes physically or mentally disabled, whether totally or
partially, as evidenced by the written statement of a competent physician
licensed to practice medicine in the United States,

<PAGE>
so that the Executive is unable to substantially perform his services hereunder
for (i) a period of six consecutive months, or (ii) for shorter periods
aggregating six months during any period of twelve consecutive months, the
Company may at any time after the last day of the six consecutive months of
disability or the day on which the shorter periods of disability equal an
aggregate of six months within a period of twelve consecutive months, by written
notice to the Executive, terminate the Executive's employment hereunder. If such
right is exercised, the Company's obligation to the Executive shall be as set
forth in Section 5.5 below.

               5.5 SEVERANCE BENEFIT. If at any time during or after the
Employment Term, the Executive's employment by the Company is terminated for any
reason other than (i) a termination for Cause under Section 5.2, (ii) his
voluntary resignation, or (iii) his death, then for a period of one year
following the date of termination of the Executive's employment (the "INITIAL
SEVERANCE BENEFIT PERIOD"), the Company shall continue to (a) pay to the
Executive, in payroll period installments in accordance with the Company's
normal payroll policies, the amount of Annual Salary in effect at the date of
termination of his employment and (b) at the Company's expense, continue to
include the Executive and his eligible dependents under the coverage of all
group health, medical and dental insurance policies, plans and programs
maintained by the Company during Initial Severance Benefit Period for the
Company's employees, or management employees, generally.

        The Company, at its option, which shall be exercisable by a written
notice sent to the Executive at least 60 days prior to the expiration of the
Initial Severance Benefit Period, may elect to extend the Initial Severance
Benefit Period for a period of an additional one year following the expiration
of the Initial Severance Benefit Period (the "SECOND SEVERANCE BENEFIT PERIOD").
If the Company so elects to extend the Initial Severance Benefit Period, the
Company, during the Second Severance Benefits Period, shall (i) pay to the
Executive, in payroll period installments in accordance with the Company's
normal payroll policies, an amount equal to 50% of the Annual Salary in effect
at the date of termination of his employment and (ii) at the Company's expense,
continue to include the Executive and his eligible dependants under the coverage
of all group health, medical and dental insurance policies, plans and programs
maintained by the Company during the Second Severance Benefit Period for the
Company's employees, or management employees, generally.

        For purposes of Section 4.1.1 of this Agreement, the term "TOTAL
SEVERANCE BENEFIT PERIOD" means the total period (including the Initial
Severance Benefit Period and, if applicable, the Second Severance Benefit
Period) during which the Company is obligated to pay and provide, and performs
its obligations to pay and provide, severance benefits to the Executive under
this Section 5.5

        6. INSURANCE. The Company may, from time to time, apply for and take
out, in its own name and at its own expense, naming itself or others as the
designated beneficiary (which it may change from time to time), policies for
health, accident, disability or other insurance upon the Executive or his life,
in any amount or amounts that it may deem necessary or appropriate to protect
its interest. The Executive agrees to aid the Company in procuring such
insurance by submitting to reasonable medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance
<PAGE>
company or companies to which any application or applications for insurance may
be made by or for the Company.

<PAGE>
                             EMPLOYMENT AGREEMENT

      THIS AGREEMENT dated as of April 10, 1998, between Gulsby Engineering,
Inc., a Texas corporation (the "COMPANY"), and Jerry G. Gulsby, a resident of
Kingwood, Texas, the ("EXECUTIVE"),

                             W I T N E S S E T H:

      WHEREAS, on the date of this Agreement, the Company, OEI International,
Inc., a Delaware corporation ("OEI"), GEI Acquisition, Inc., a Texas corporation
and a wholly owned subsidiary of OEI (the "MERGER SUBSIDIARY"), and the
stockholders of the Company, including the Executive, are entering into an
Agreement and Plan of Reorganization (the "ACQUISITION AGREEMENT"), under which
the Company will merge with the Merger Subsidiary in a merger (the "MERGER") of
which the Company will be the surviving corporation and as a result of which the
Company will become a wholly owned subsidiary of OEI; and

      WHEREAS, The Executive founded the Company, has served as an officer and
director of the Company since its inception, and has contributed substantially
to the Company's growth and success; and

      WHEREAS, OEI wishes to insure that the Company will have the continued
benefit of the Executive's knowledge and experience concerning the affairs of
the Company and the engineering services industry generally, and to keep them
from being availed of by third parties, and has therefore required as a
condition to its execution of the Acquisition Agreement that the Executive enter
into this Agreement to become effective upon consummation of the Merger; and

      WHEREAS, the Executive is willing to accept employment by the Company on
the terms and conditions of this Agreement;

      NOW, THEREFORE, the Company and the Executive agree as follows:

      1.    EMPLOYMENT, DUTIES AND ACCEPTANCE.

            1.1 EMPLOYMENT BY THE COMPANY. The Company agrees to employ The
Executive as the Chairman and Chief Executive Officer of the Company for the
duration of the Employment Term (as defined in Section 2 below), to render such
services and to perform such duties as are normally associated with and inherent
in the executive capacity in which the Executive will be serving, as well as
such other duties, which are not inconsistent with the Executive's position as
an executive of the Company, as shall from time to time reasonably be assigned
to him by the Board of Directors of the Company (the "BOARD OF DIRECTORS").

            1.2 ACCEPTANCE OF EMPLOYMENT BY THE EXECUTIVE. The Executive accepts
such employment for the Employment Term and agrees to render the services
required of him under Section 1.1. During the Employment Term, the Executive
shall devote his full business time,

                                      1
<PAGE>
attention and energy to the business of the Company and the performance of his
duties under this Agreement. The foregoing shall not, however, prohibit the
Executive from making and overseeing personal investments, including management
of his existing ownership interest in an ammonia plant in Gordon, Georgia
previously operated by Shoreline Chemical and the Patterson Gas processing Plant
in Patterson, Louisiana, or from engaging in civic or charitable activities,
that do not materially impair the performance of his duties under this
Agreement. If appointed or elected, as applicable, the Executive also shall
serve during all or any part of the Employment Term as any other officer and/or
as a director of the Company or any of its subsidiaries or affiliates, without
any additional compensation other than that specified in this Agreement.

            1.3 PLACE OF PERFORMANCE. The Executive shall be based in the
Greater Houston Metropolitan Area, and nothing in this Agreement shall require
the Executive to relocate his base of employment or principal place of residence
from the Greater Houston Metropolitan Area.

            1.4 TERMINATION OF EXISTING CONTRACTS. The Executive agrees that all
agreements and contracts, whether written or oral, relating to the employment of
the Executive by the Company shall be terminated effective as of the
commencement of the Employment Term. However, nothing in this Section 1.4 shall
(i) affect accrued vacation, holiday or sick pay accruals (but only to the
extent such accruals were reflected in the Acquired Company's financial
statements delivered to OEI pursuant to the Acquisition Agreement), (ii) require
the Acquired Company to cease to make available to the Executive, and, subject
to his meeting all applicable eligibility requirements, the Executive shall be
entitled to continue to be covered under, all group health, medical and dental
insurance policies, plans and programs maintained by the Company for its
employees generally, in each case until replacement coverage is provided by the
Company, or (iii) impair or adversely affect any indemnification rights that
Executive may have under statutes empowering corporations in the Acquired
Company's state of incorporation to indemnify their officers and directors, or
under the Acquired Company's bylaws or any written indemnification agreement
between the Executive and the Acquired Company implementing such statutory
indemnification rights, but only with respect to third-party claims or
proceedings that relate to actions taken by the Executive as an officer or
director of the Acquired Company prior to the date hereof and that are disclosed
to OEI in the Disclosure Statement delivered to OEI pursuant to the Acquisition
Agreement or, if asserted or brought for the first time after the date hereof,
would not constitute a breach of the representations or warranties of the
Acquired Company or its stockholders under the Acquisition Agreement.

      2. EMPLOYMENT TERM. The term of the Executive's employment under this
Agreement (the "EMPLOYMENT TERM") shall commence on the date of consummation of
the Merger pursuant to the Acquisition Agreement (the "COMMENCEMENT DATE"), and
shall continue through and expire on the third anniversary of the Commencement
Date (the "EXPIRATION DATE"), unless earlier terminated as herein provided.
However, if the Acquisition Agreement is terminated under the terms of its
Article XII, then this Agreement shall also terminate, automatically and without
the requirement of any action on the part of either of its parties.

            2.1 CONSULTING CONTRACT. On the Expiration Date, the Company, at it
sole and exclusive option, may offer to engage Executive in a consulting
capacity. If the Company elects to

                                      2
<PAGE>
offer such a consulting contract to Executive, the contract shall be for a
period of up to two years, and shall be on substantially the same salary and
benefit terms contained herein.

      3.    COMPENSATION AND OTHER BENEFITS.

            3.1 ANNUAL SALARY. As compensation for services to be rendered under
this Agreement, the Company shall pay the Executive a salary (the "ANNUAL
SALARY"), subject to such increases as the Board of Directors may, in its
discretion, approve, at a rate of $225,000 per annum. The Executive shall also
be eligible, during the Employment Term, to receive such other compensation,
whether in the form of cash bonuses, incentive compensation, stock options,
stock appreciation rights, restricted stock awards or otherwise (collectively,
the "ADDITIONAL COMPENSATION"), as the Board of Directors (or any committee of
the Board) may, in its discretion, approve. The Annual Salary and the Additional
Compensation shall be payable in accordance with the applicable payroll and/or
other compensation policies and plans of the Company as in effect from time to
time during the Employment Term, less such deductions as shall be required to be
withheld by applicable law and regulations.

            3.2 PARTICIPATION IN EMPLOYEE BENEFIT PLANS. The Executive shall be
permitted, during the Employment Term, if and to the extent he is and continues
to meet all applicable eligibility requirements, to participate in any group
life, hospitalization or disability insurance plan, health program, pension
plan, similar benefit plan or other "fringe benefits" of the Company, which may
be available to all other members of the Company's management on generally the
same terms.

            3.3 EXECUTIVE SUPPORT. The Company shall provide to the Executive
office facilities, furniture, and equipment, secretarial and support personnel
and other management level support services as the Executive shall reasonably
require in connection with his performance of his duties under this Agreement.

            3.4 REIMBURSEMENT OF BUSINESS EXPENSES. The Executive may incur
reasonable, ordinary and necessary business expenses in the course of his
performance of his duties under this Agreement, including expenses for travel,
food and entertainment. The Company shall reimburse the Executive for all such
business expenses if (i) the expenses are incurred by the Executive in
accordance with the Company's business expense reimbursement policy, if any, as
may be established and modified by the Company from time to time, and (ii) the
Executive provides to the Company a record of and appropriate receipts for (A)
the amount of the expense, (B) the date, place and nature of the expense, (C)
the business reason for the expense and (D) the names, occupations and other
data concerning individuals entertained sufficient to establish their business
relationship to the Company. The Company shall have no obligation to reimburse
the Executive for expenses that are not incurred and substantiated as required
by this Section 3.4.

            3.5 AUTOMOBILE. The Company shall provide the Executive with the use
of a Company-owned or leased automobile for use by the Executive in connection
with the performance of his duties under this Agreement, and shall pay the
reasonable costs of insuring, operating and maintaining the automobile, or, in
lieu thereof the Company, at is option, may pay to the Executive an automobile
allowance to help defray the Executive's cost of owning and operating a personal

                                      3
<PAGE>
automobile for such purpose. Such Company furnished automobile or such allowance
shall be comparable to the automobile or allowance that was taken into account
in determining the merger consideration that is to be paid by the Company to the
Company's stockholders pursuant to the Acquisition Agreement.

      4.    NON-COMPETITION.

            4.1 COVENANTS AGAINST COMPETITION. The Executive acknowledges that
(i) the Company, which for purposes of this Section 4 includes OEI and all of
its present and future subsidiaries and affiliates, including subsidiaries and
affiliates that may be formed or incorporated during the Restricted Period (as

protect the Business and the goodwill of the Company; (vi) he has means to
support himself and his dependents other than by engaging in the Business in

not impair his ability to do so. Accordingly, the Executive agrees as follows:

                  4.1.1 NON-COMPETE. During the Restricted Period, the Executive
      shall not (A) engage, anywhere within the Territory (as hereinafter

      business selling or providing any services which are sold or offered by
      the Company, within the territory surrounding each office or fabrication
      facility (each a "FACILITY") at which the Executive was employed by the
      Company within the three-year period immediately preceding the date of the
      Executive's termination of employment (for purposes of this Section 4.1,
      the territory surrounding a facility shall be: (A) the city, town or
      village in which the facility is located, (B) the county or parish in

      HOWEVER, that nothing in this Section 4.1.1 shall prohibit the Executive
      from owning, directly or indirectly, solely as an investment, securities
      of any entity traded on any national securities exchange or
      over-the-counter market if the Executive is not a controlling person of,
      or a member of a group which controls, such entity and does not, directly
      or indirectly, own one percent or more of any class of securities of such
      entity. As used in this Section 4, the term "RESTRICTED PERIOD" means the
      period beginning on the Commencement Date and ending:

                                      4

      consultant to the Company, the Executive shall not call on any Acquisition
      Candidate (as defined below in this Section 4.1.6), with the knowledge of
      such Acquisition Candidate's status as such, for the purpose of acquiring,
      or arranging the acquisition of, that Acquisition Candidate by any person
      or entity other than the Company. In this Section 4.1.6 "ACQUISITION
      CANDIDATE" means any person or entity engaged in any of the businesses of
      providing professional engineering services, and (i) which was called on
      by the Company, in connection with the possible acquisition by the Company
      of that person or entity, or (ii) with respect to which the Company has
      made an acquisition analysis.

            4.2 RIGHTS AND REMEDIES UPON BREACH. If the Executive breaches or
threatens to commit a breach of the Restrictive Covenants, the Company shall
have the following rights and remedies, each of which shall be independent of
the others and severally enforceable, and each of which is in addition to, and
not in lieu of, any other rights and remedies available to the Company under law
or in equity:

                  4.2.1 SPECIFIC PERFORMANCE. The right and remedy to have the
      Restrictive Covenants specifically enforced by any court of competent
      jurisdiction, it being agreed that any breach or threatened breach of the
      Restrictive Covenants would cause irreparable injury to the Company and
      that money damages would not provide an adequate remedy to the Company.

                  4.2.2 ACCOUNTING. The right and remedy to require the
      Executive to account for and pay over to the Company all compensation,
      profits, monies, accruals, increments or other benefits derived or
      received by the Executive as the result of any transaction constituting a
      breach of the Restrictive Covenants.

            4.3 SEVERABILITY OF COVENANTS. The Executive acknowledges and agrees
that the Restrictive Covenants are reasonable and valid in geographical and
temporal scope and in all other respects. If any court determines that any of
the Restrictive Covenants, or any part thereof, is invalid or unenforceable, the
remainder of the Restrictive Covenants shall not thereby be affected and shall
be given full effect, without regard to the invalid portions.

            4.4 REFORMATION. If any court determines that any Restrictive
Covenant, or any part thereof, is unenforceable because of the duration or
geographic scope of such provision, such court shall have the power to reduce
the duration or scope of such provision, as the case may be, and, in its reduced
form, such provision shall then be enforceable.

                                      6
<PAGE>
            4.5 ENFORCEABILITY IN JURISDICTIONS. The Company and the Executive
intend to and hereby consent to jurisdiction to enforce the Restrictive
Covenants upon the courts of any jurisdiction within the geographical scope of
the Restrictive Covenants. If the courts of any one or more of such
jurisdictions hold the Restrictive Covenants unenforceable by reason of the
breadth of such scope or otherwise, it is the intention of the Company and the
Executive that such determination not bar or in any way affect the Company's
right to the relief provided above in the courts of any other jurisdiction
within the geographical scope of the Restrictive Covenants, as to breaches of
such covenants in such other respective jurisdictions, such covenants as they
relate to each jurisdiction being, for this purpose, severable into diverse and
independent covenants.

      5.    TERMINATION.

            5.1 TERMINATION UPON DEATH. If the Executive dies during the
Employment Term, this Agreement shall terminate, except that the Executive's
legal representatives, successors, heirs or assigns shall be entitled to receive
the Annual Salary, the Additional Compensation and other accrued benefits, if
any, earned up to the date of the Executive's death; PROVIDED, HOWEVER, if any
Additional Compensation or other benefits are governed by the provisions of any
written employee benefit plan or policy of the Company, any written agreement
contemplated thereunder or any other separate written agreement entered into
between the Executive and the Company, the terms and conditions of such plan,
policy or agreement shall control in the event of any discrepancy or conflict
with the provisions of this Agreement regarding such Additional Compensation or
other benefit upon the death, termination or disability of the Executive.

            5.2 TERMINATION FOR CAUSE. At any time during the Employment Term,
the Company shall have the right, exercisable by serving notice effective in
accordance with its terms, to terminate the Executive's employment under this
Agreement and discharge the Executive for Cause. If such right is exercised, the
Company's obligation to the Executive shall be limited to the payment of any
unpaid Annual Salary, Additional Compensation and other benefits, if any,
accrued up to the effective date specified in the Company's notice of
termination (which date shall not be retroactive). As used in this Section 5.2
and elsewhere in this Agreement, term "CAUSE" shall mean that a majority of the
Board of Directors shall have determined, and a majority of the Board of
Directors of OEI shall have concurred, that (i) after notice and a right to
cure, there has been a material breach by the Executive of the terms of this
Agreement, (ii) after receipt of a written warning, the Executive has willfully
and persistently failed or refused to follow the reasonable policies and
directives established by the Board of Directors or executive officers of the
Company senior to the Executive, (iii) the Executive has wrongfully
misappropriated money or other assets or properties of the Company or any
subsidiary or affiliate of the Company, (iv) the Executive has been convicted of
any felony or other serious crime, (v) the Executive's employment performance
has been substantially impaired by chronic absenteeism, alcoholism or drug
addiction, or (vi) the Executive has exhibited gross moral turpitude relevant to
his office or employment with the Company or any subsidiary or affiliate of the
Company.

            5.3 TERMINATION UPON DISABILITY. If during the Employment Term the
Executive becomes physically or mentally disabled, whether totally or partially,
as evidenced by the written statement of a competent physician licensed to
practice medicine in the United States, so that the Executive is unable to
substantially perform his services hereunder for (i) a period of six consecutive

                                      7
<PAGE>
months, or (ii) for shorter periods aggregating six months during any period of
twelve consecutive months, the Company may at any time after the last day of the
six consecutive months of disability or the day on which the shorter periods of
disability equal an aggregate of six months within a period of twelve
consecutive months, by written notice to the Executive, terminate the
Executive's employment hereunder. If such right is exercised, the Company's
obligation to the Executive shall be as set forth in Section 5.4 below.

            5.4 SEVERANCE BENEFIT. If at any time during or after the Employment
Term, the Executive's employment by the Company is terminated for disability
pursuant to Section 5.3, then for a period of one year following the date of
termination of the Executive's employment (the "SEVERANCE BENEFIT PERIOD"), the
Company shall continue to (a) pay to the Executive the amount of Annual Salary
in effect at the date of termination of his employment and (b) at the Company's
expense, continue to include the Executive and his eligible dependents under the
coverage of all group health, medical and dental insurance policies, plans and
programs maintained by the Company during Severance Benefit Period for the
Company's employees, or management employees, generally.

      6. INSURANCE. The Company may, from time to time, apply for and take out,
in its own name and at its own expense, naming itself or others as the
designated beneficiary (which it may change from time to time), policies for
health, accident, disability or other insurance upon the Executive or his life,
in any amount or amounts that it may deem necessary or appropriate to protect
its interest. The Executive agrees to aid the Company in procuring such
insurance by submitting to reasonable medical examinations and by filling out,
executing and delivering such applications and other instruments in writing as
may reasonably be required by an insurance company or companies to which any
application or applications for insurance may be made by or for the Company.
