Readers of this report should be aware that the following important factors,
among others, in some cases have affected, and in the future could affect the
Company's actual results and could cause the Company's actual consolidated
results for the first quarter of 1998, and beyond, to differ materially from
those expressed in any forward-looking statements made by, or on behalf of, the
Company:

  Reliance on Key Clients.  The Company's success is dependent upon its ability
to maintain its existing clients and obtain new clients.  The loss of one or
more of the Company's large clients or a significant reduction in business from
such clients could have a material adverse effect on the Company.  The Company's
largest client is General Motors Corporation ("GM").  The Company's various
contracts with GM accounted for 17%, 25% and 22% of the Company's revenues for
the years ended 1997, 1996 and 1995, respectively.  The Company's focus on
attracting larger projects and establishing long-term client relationships may
increase the Company's reliance on particular projects and clients.  Although
the Company's ongoing projects may generally be terminated by its clients at any
time, funds for work completed are normally recoverable.

  Fluctuations in Demand for Company Services.  Demand for the Company's
services can be affected by a number of factors outside the Company's control,
including marketing budgets, economic conditions, consolidations and other
industry-specific trends, and changes in management or ownership of a client.
As a result, the Company's revenues and operating results may fluctuate.

  Business Strategy Regarding Acquisitions and International Expansion.  Part of
the Company's business strategy is to expand domestically, internationally, and
to extend into related businesses through strategic acquisitions.  There can be
no assurance that the Company's services will be widely accepted as it seeks to
expand in international markets.  International expansion will also subject the
Company to risks inherent in doing business abroad, including adverse
fluctuations in currency exchange rates, limitations on asset transfer, changes
in foreign regulations and political turmoil.  Furthermore, there can be no
assurance that the Company will be able to integrate successfully the operations
of any subsequently acquired company with its own operations.

  Dependence on Key Personnel.  The Company is dependent upon the efforts and
skills of its Chairman and certain other key senior executives.  The loss of the
services of one or more of these individuals could have a material adverse
effect on the Company.

  Competition.  The Company faces competition in connection with most of the
individual services and products it provides.  Although the Company believes
that no single competitor offers a comparable combination of services and
products, there can be no assurance that other companies, some with greater
financial resources than the Company, will not attempt to offer a range of
services and products similar to those offered by the Company, or otherwise
compete more effectively in the business-to-business market research and
information services industry.  For consumer market research services, the
Company regularly experiences significant competition from a large number of
competitors, including consumer market research companies, advertising agencies
and business consulting firms.

Item 1.   Business
          --------

GENERAL

          Opinion Research Corporation (the "Company") was established in 1938
to apply the principles of general public opinion polling to marketing issues
facing America's largest companies.  The Company has evolved to provide primary
market research, information services, and marketing services, including a focus
on businesses selling primarily to other businesses.  The Company assists
clients in evaluating, monitoring and optimizing the effectiveness of their
marketing and sales.  The Company's services and products address issues such as
customer satisfaction, market demand and forecasting, corporate image,
competitive positioning, and telemarketing.

          In August 1993 the Company acquired all of the stock of Gordon Simmons
Research Group, Ltd. ("GSR"), substantially increasing the Company's presence in
the U.K. and expanding the international aspects of its business.  In April of
1994 the Company acquired all of the stock of Strategic Research and Consulting
("SRC").  The SRC acquisition gave the Company access to the U.S. automotive
industry.  In August of 1995 the Company opened a branch office in Hong Kong and
continued to expand internationally with the formation of GSR/SIA Limited
("GSR/SIA") in the U.K. in the latter part of 1996.  In purchasing the assets of
a division of an information technology company, GSR/SIA expanded the Company's
capabilities in servicing international clients and introduced the Company to
the U.K. public sector.  During 1997, as part of its globalization strategy, the
Company acquired a presence in Korea, Taiwan, and Mexico and created ORC
TeleServices, a telemarketing company in Tampa, Florida.  The year concluded
with the announcement of the acquisition of ProTel Marketing, Inc., a high
quality telemarketing company based in Lansing, Illinois.  This acquisition was
completed on January 6, 1998.  A Form 8-K was filed on January 20, 1998,
regarding this acquisition.

          The Company collects customer and market information through computer
assisted telephone interviews, personal interviews, mail questionnaires and
specialized techniques such as business panels.  Management believes that the
Company's substantive expertise in certain industries, including automotive,
financial services, and telecommunications enables it to provide reliable
customer and market information and advisory services to clients in those
industries.  The Company also believes that its recognized name and long-
standing reputation enable it to obtain information from senior executives who
are difficult to access.

          The Company's strategy focuses on client projects that require
periodic updating and tracking of information, thereby creating the potential
for higher-margin recurring revenues.  The portion of the Company's revenues
from such projects was approximately 51% in 1997.

THE COMPANY'S SERVICES AND PRODUCTS

          The Company offers a variety of services and products to assist
clients with their strategies and plans for marketing and selling their products
to businesses and consumers.

Services

          Customer Loyalty & Retention.  The Company assists its clients in
quantifying customer loyalty and increasing customer retention.  By capturing
and analyzing the perceptions and experiences of its clients, prospects and
employees, the Company provides analysis and feedback on customer loyalty which
drives superior customer retention and business performance.  The Company
provides its clients with information on the elements of products or services
which are most important to their customers; on how well these products and
services compare to the competition; and on which customers will continue to
purchase and recommend such products and services.

          Corporate Reputation & Branding.  The Company works with clients
worldwide to manage their corporate and brand images; identify and achieve
optimal positioning in the marketplace; and strengthen equity with customers,
employees and the financial community.  The strength of a client's image or
reputation is identified through interviews with constituency groups with whom
the client interacts and whose decisions influence the client's success.  These
groups may include customers, potential customers, distributors, suppliers, the
media and the investment community.

          Market Demand Analysis & Forecasting.  The Company works with clients
worldwide to analyze and forecast market demand for new products and services.
The Company combines sophisticated analytic techniques with global reach to
provide clients with insight regarding optimal product/services configuration
and pricing, as well as market size information.  This work supports clients'
business planning and capital generation for new ventures.

          Advanced Analytics & Data Modeling.  The Company's diagnostic and
statistical models are among the most sophisticated in market research and will
redefine the teleservices industry.  The Company applies advanced market
research techniques and uses predictive segmentation learning models to improve
teleservices success rates.  By focusing on its clients' business issues and the
application of the right analytic tools, the Company can effectively transform
data and analyses into intelligence and insight.  This approach holds whether
the Company is designing traditional market research surveys, "data mining"
client databases to optimize marketing efforts or building dynamic models to
guide telemarketers on selecting target prospects and product offerings.

                                      -2-
<PAGE>
 
          Employee Survey Programs.  The Company provides comprehensive
employee-related research services to measure satisfaction, increase staff
retention, reduce hiring and training costs, and improve customer service.
Using proprietary computer software, exclusive multi-industry benchmarking
databases and a combination of quantitative and qualitative methodologies, the
Company works with clients to identify strengths and weaknesses.  The Company
implements all stages of program management, from questionnaire design and
processing through reporting, final analysis and recommendations for action.

          Data Collection & Processing.  The Company's telephone interviewing
Call Centers in North America and Europe combine research expertise,
verification and advanced telecommunications technology.  These facilities,
staffed with multilingual interviewers, use Computer Assisted Telephone
Interviewing (CATI), which provides clients with highly efficient and cost
effective data and information collection.

          TeleServices. The Company combines its market research expertise in
predictive segmentation modeling and database management with top quality
teleservices to quantify buyer behavior, optimize targeting of its clients'
customers and provide feedback from its clients' customers for "continuous loop"
marketing to improve sales. This breakthrough capability -- ORC TeleScience(sm)
- -- applies sophisticated modeling techniques to cutting-edge teleservices to
increase the overall success rate of telemarketing as measured by higher sales
yields and lower costs of customer acquisition.

Industries

          Telecommunications and Information Technology.  The Company provides
market knowledge for a range of telecommunications and information technology
companies, from wireless communications companies and telephone carriers to
Internet service providers and computer hardware and software firms.  Its
services include market definition, segmentation, new product development,
customer retention, usage analysis, competitive profiling and market demand
analysis for satellite communications products.

          Among its services, the Company helps clients determine pricing and
distribution systems, tracks service performance, gauges the success of products
and services, designs and configures new products, predicts customer needs and
defines competitive positions in new markets.

          Financial Services. The Company provides market and customer
intelligence to banks, securities brokerage, insurance companies and other
financial institutions across a number of business issues: customer loyalty and
retention, image management, market segmentation and positioning, new product
development, pricing strategy and customer database management.

                                      -3-
<PAGE>
 
          By focusing its research efforts on key customer segments such as high
net worth individuals, corporate treasurers, active investors, policyholders,
etc. the Company can determine the specific factors that influence the target
groups' decisions, and design strategies to attract, retain and motivate them
effectively.

          Automotive.  Utilizing research methodologies developed for its
automotive industry clients, the Company has extensive experience working with a
wide range of companies around the world, including vehicle manufacturers,
original-equipment-manufacturers (OEM) suppliers, dealers, distributors,
trucking companies and heavy equipment manufacturers.

          The Company provides sophisticated segmentation research and long-term
studies on retailing sales and service; brand image and equity; product
development, design and performance; and dealer/manufacturer relations. The
Company's exclusive consumer market analysis evaluates and tracks customer needs
as they relate to new vehicle purchase, financing and leasing, buying behavior
and brand loyalty.

          Retail and Trade.  To shape marketing strategy, the Company's areas of
specialization  include understanding the determinants of store choice; customer
loyalty and satisfaction; mystery shopping; segmentation and positioning; store
location, layout, design and product positioning; merchandise performance;
development and appraisal of individual outlets and sites; and diversification
into new markets, both international and local.

          The Company also works in partnership with manufacturers and suppliers
of consumer goods to understand the needs, behavior and attitudes of customers
at all stages in the distribution channel.  The Company's aim is to enhance the
manufacturer/trade/consumer relationship.

          Health Care.  The Company's services include surveys and evaluations
to determine patient satisfaction, market segmentation and customer acquisition,
competitive analysis, community needs assessment, market segmentation and
corporate positioning.  For pharmaceutical companies and HMOs and for hospitals
and health care providers, the Company also conducts loyalty and retention
modeling research as part of its clients' patient and employee satisfaction
programs.

          Through its innovative methodologies, such as proprietary panels, the
Company establishes ongoing dialogues with difficult-to-reach decision-makers
such as physicians, plan administrators and benefits managers.

Products

          The following products are used by the Company to deliver some of the
services listed above and are also marketed as stand-alone products:

                                      -4-
<PAGE>
 
          Business Panels. The Company develops business panels to access
executives and professionals. Panels are composed of executives and
professionals who have agreed in advance to participate in an on-going series of
interviews with the Company for the purpose of gathering customer and market
information.

          The Company owns and operates a number of proprietary panels.  The
panels range in size from several hundred to several thousand panelists.  These
panels have been created with no predetermined end date.

          The creation of a business panel involves considerable planning, time
and expense.  Once established, however, it provides a significant amount of
reliable information that can be collected and updated from a relatively
constant source with less time and expense than would be otherwise required.  As
such, the Company believes that there are strong financial incentives for
clients to continue using a panel.

          Business panels produce up-to-date market intelligence that can be
used by the client for decisions ranging from marketing and sales strategies to
"micro-marketing" plans for specific market niches or segments.  Typical issues
addressed by business panels include customer satisfaction, pricing and sales
strategy, market receptivity to new or potential products or services and market
share information.

          Shared-Cost Programs.  For over 30 years, the Company has conducted
shared-cost telephone survey programs, marketed under the name "CARAVAN," in
which questions from a number of clients are combined in a series of interview
questionnaires.  The CARAVAN programs provide multiple clients with high-
quality, timely information at a relatively low cost.

          The general public CARAVAN is a weekly shared-cost national survey
combining questions of clients such as advertising agencies, public affairs
departments of large corporations and product managers.  Typically, the
information collected from the CARAVAN survey provides measurement and
evaluation of advertising and products.

          Developed in 1994, CORPerceptions profiles the image of major
corporations that serve the needs of other business establishments located in 16
countries around the world.  Telephone or in-person interviews are completed
annually with approximately 1,200 senior business executives selected from the
largest industrial and services companies within these countries.  Industries
profiled by executives include automotive, brokerage services, computer
hardware, electronics, information technology services, and management
consulting.

          CORPerceptions' sister-study, BrandPerceptions, is an international
brand equity study conducted among 4,250 consumers in 16 countries throughout
Asia Pacific, Europe and North America.  As a result of BrandPerceptions,
conducted for the first time in 1996, some of the world's leading companies
learn more about consumer awareness, preference, satisfaction and loyalty toward
their brand and competing brands in the international marketplace.

                                      -5-

          Customers for Life is a software-based customer retention tool
designed to build and strengthen customer relationships and long-term customer
loyalty.  Developed in 1997, Customers for Life is a comprehensive program that
provides the framework for direct customer feedback, real-time troubleshooting,
database management and structured reporting systems.

MARKETING

          In 1997, the Company increased the number of initiatives to further
market its services and products.  These include:
 
          Global Corporate Identity Program.  The Company established a unified
appearance and design to ensure the consistent delivery of marketing messages
and a uniform graphic treatment around the world.

          Marketing and Sales-Support Program.  The Company developed and
implemented a comprehensive communications program to support a systematic
business development effort.  Elements include advertising, direct marketing,
sales-support materials, media relations, seminars and telemarketing to gain
access to a large number of prospective clients.  The Company's web site allows
prospective clients to learn about its products and services at a time of their
choosing.

CLIENTS AND CLIENT RELATIONSHIPS

          Some of the Company's largest clients in terms of revenues generated
include Bell Atlantic, Coopers & Lybrand, Dean Witter, EDS Corp., GE, General
Motors, Moody's Investor Service, Inc., PNC Bank, SBC, and the U.S. Postal
Service.  In 1997, the Company served over 550 clients.  For many clients, the
Company performed multiple projects, sometimes for different subsidiaries or
business units of the same client.

          In 1997, the Company was engaged by 12 divisions of GM, including GM
Corporate, covering such issues as customer satisfaction, product positioning,
buyer behavior, and brand and corporate image.  Collectively, these projects
generated approximately 17% of the Company's revenues. GM has been a client of
ORC's automotive practice, since 1985.

COMPETITION

          Many other firms provide some of the services and products provided by
the Company, typically focusing on consumer markets.  However, the Company
believes that no single competitor offers a comparable combination of services
and products.

                                      -6-
<PAGE>
 
          For business to business market research, the Company believes that it
competes for clients based on a variety of factors, including name recognition,
reputation, expertise in a variety of industries, ability to access executives
and other key constituencies, ability to collect accurate and representative
information, ability to enhance the value of the data collected through analysis
and consulting, technological competence, reliability, promptness and
efficiency.  In the Company's experience, rather than price, its typical clients
are interested primarily in the quality and utility of the service received.

          For consumer market research services, the Company regularly
experiences significant competition from a large number of competitors,
including marketing and research departments of various companies, advertising
agencies and business consulting firms.  Price, reputation, and quality of
service are the dominant considerations.

          The Company considers the relationship with its clients as well as its
know-how and expertise as invaluable assets.  The Company seeks to safeguard
these assets by requiring each of its senior employees to execute
confidentiality and non-solicitation agreements.

BACKLOG

          As of December 31, 1997, revenues expected to be received by the
Company under its client contracts, which are based on budgeted amounts in those
contracts, were $26,092, as compared to $12,154 as of December 31, 1996.  This
increase in backlog is due to the timing associated with the renewal of certain
projects as well as increased sales activity in the fourth quarter of 1997.  All
of the 1997 amount is expected to be received by December 31, 1998.  The
Company's engagements generally are terminable by the Company's clients at any
time, with the expectation of cost recovery for work completed by the Company.

November 2004.  ORC's U.K. companies are housed in two leased locations in
London and a third location in Manchester, England.  One location is
approximately 16,000 square feet, and the lease for such premises expires in May
2002.  The second London lease is for 2,600 square feet and expires December
1998.  The Manchester lease is for 2,600 square feet and expires December 1998.
The ORC Automotive Group occupies approximately 25,000 square feet in Maumee
(Greater Toledo), Ohio under a lease that expires in June 2000 and 2,400 square
feet in Detroit, Michigan that expires in May 2000, with a five-year renewal
option.

          The Tucson and London centers presently have a combined total of 272
computer assisted telephone interviewing stations.  All of these facilities are
equipped with state-of-the-art hardware and software.  In a typical telephone
interview, the computer assisted telephone interviewing system prompts the
interviewer's sequence of questions depending on the previous answers.  All
responses are recorded directly into the computer, avoiding the need for
subsequent data entry and enabling prompt analysis of responses.  The
interviewees communicate with live interviewers at all times.

          Over the past several years the Company has installed database systems
and software to store information in its Toledo, Tucson, and London centers.
These systems and software expand the Company's reporting capabilities and
transform traditional tabular formats into graphic output, thereby improving the
utility and presentation of reports as well as the turnaround times.

          The Company believes that its properties are sufficient for its
current operational needs.

          ---------------------------------------------------------------
          
          Results of Operations
          ---------------------

OVERVIEW

          The Company was established in 1938 to apply the principles of general
public opinion polling to marketing issues facing America's largest companies.
The Company has evolved to provide primary market research, information
services, and marketing services, including a focus on businesses selling
primarily to other businesses.  The Company assists clients in evaluating,
monitoring and optimizing the effectiveness of their marketing and sales.  The
Company's services and products address issues such as customer satisfaction,
market demand and forecasting, corporate image, competitive positioning, and
telemarketing.

          In August 1993 the Company acquired all of the stock of GSR,
substantially increasing the Company's presence in the U.K. and expanding the
international aspects of its business.  In April of 1994 the Company acquired
all of the stock of SRC.  The SRC acquisition gave the Company access to the
U.S. automotive industry.  In August of 1995 the Company opened a branch office
in Hong Kong and continued to expand internationally with the formation of
GSR/SIA in the U.K. in the latter part of 1996.  In purchasing the assets of a
division of an information technology company, GSR/SIA expanded the Company's
capabilities in servicing international clients and introduced the Company to
the U.K. public sector.  During 1997, as part of its globalization strategy, the
Company acquired a presence in Korea, Taiwan, and Mexico and created ORC
TeleServices, a telemarketing company in Tampa, Florida.  The year concluded
with the announcement of the acquisition of ProTel Marketing, Inc., a high
quality telemarketing company based in Lansing, Illinois.  This acquisition was
completed on January 6, 1998.

RESULTS OF OPERATIONS - 1997 COMPARED TO 1996

Revenues

          Revenues from the U.S., GSR, and Hong Kong grew to $48,891, or 5.6%,
in 1997 from $46,299 in 1996.  Additionally, revenues increased by 19.9% to
$56,673 in 1997 from $47,273 in 1996.  $3,930, or 41.8% of this increase in
revenues resulted from the acquisition of Korea and Taiwan and the creation of
TeleServices in Tampa.  An additional $2,878, or 30.6%, of this increase is
attributed to the inclusion of the results of operations of GSR/SIA for all of
1997 as opposed to only three months in 1996.

Cost of Revenues

          Cost of revenues increased 13.5% to $34,374 in 1997 from $30,281 in
1996.  As a percentage of total revenues, cost of revenues decreased to 60.7% in
1997 from 64.0% in 1996.  The decrease in cost of revenues, as a percentage of
revenues, reflects the greatly increased revenues in 1997 generated by a
relatively stable workforce.  Additionally, change in the mix of business to
more value added engagements contributed to the relative decline in the cost of
revenues.

Selling, General, and Administrative Expenses

          Selling, general and administrative expenses ("SG&A") increased to
$16,844 in 1997 from $12,214 in 1996.  As a percentage of revenues, SG&A
increased to 29.7% in 1997 from 25.8% in 1996.  $2,240 or 48.4% of the absolute
increase in SG&A can be attributable to the addition of Korea, Taiwan, and the
creation of TeleServices and GSR/SIA being present for an entire year.  SG&A
expenditures increased throughout the year as the Company's performance improved
quarter over quarter.  Expenditures in 1997 for such items as indirect
personnel, recruitment, placement fees, public relations and promotions, and
legal and accounting fees all exceeded 1996 levels.

Depreciation and Amortization Expense

          Depreciation and amortization expense increased 12.8 % to $2,654 in
1997 from $2,353 in 1996.  As a percentage of revenues, depreciation and
amortization expense declined to 4.7% in 1997 from 5.0% in 1996.  The increase
in the absolute amount of depreciation and amortization is principally
attributable to the addition of Korea, Taiwan and the inclusion of GSR/SIA for
the full year in 1997.

Provision for Income Taxes

          The provision for income taxes for 1997 and 1996 are $976 and $840,
respectively. The provisions in 1997 and 1996 are higher than the amount which
results from applying the federal statutory rate to income primarily because of
the amortization of non-deductible goodwill generated from pre-1996 acquisitions
and the impact of state taxes.

Net Income
          As a result of the items described above, net income for 1997
increased to $1,151, up from $808 in 1996.

RESULTS OF OPERATIONS - 1996 COMPARED TO 1995

Revenues

          Revenues increased by 7.2% to $47,273 in 1996 from $44,101 in 1995.
$974, or 31% of this increase in revenues resulted from the acquisition of
GSR/SIA in London effective October 1, 1996.  An additional $848, or 26.7%, of
this increase can be attributed to an increase in the Company's Asian
operations.  The remaining increase in revenues was due to a general improvement
in business conditions.

          Cost of revenues increased 12.8% to $30,281 in 1996 from $26,854 in
1995.  As a percentage of total revenues, cost of revenues increased to 64.0% in
1996 from 60.9% in 1995.  The increase in the cost of revenues as a percentage
of total revenues was principally due to a management decision to maintain an
increased workforce despite experiencing delays in certain contract awards.

Selling, General, and Administrative Expenses

          SG&A decreased to $12,214 in 1996 from $12,422 in 1995.  As a
percentage of revenues SG&A decreased to 25.8% in 1996 from 28.2% in 1995.  The
decline in SG&A was the result of a deliberate strategy to control SG&A costs
and increase the leverage at the SG&A line as the Company continues to expand.

Depreciation and Amortization Expense

          Depreciation and amortization expense decreased 12.1% to $2,353 in
1996 from $2,677 in 1995.  As a percentage of revenues, depreciation and
amortization expense declined to 5.0% in 1996 from 6.1% in 1995.  The decline in
depreciation and amortization was the direct result of the write down of
capitalized production cost in the second quarter of 1995 which were amortized
over three years.

Unusual Charges

          There were no unusual charges in 1996. During the second quarter of
1995, the Company announced a plan to restructure and consolidate operations,
concentrate resources, and better position itself to achieve its strategic
growth objectives. This plan resulted in a pre-tax charge of $3,489. This charge
included a $1,958 write-down of capitalized production costs related to products
discontinued as a result of the restructuring; $178 for the disposal of obsolete
fixed assets; $460 of intangible assets associated with previous acquisitions;
$380 in severance costs; $414 provision for the abandonment of leases; and other
miscellaneous charges of $99. Management does not anticipate incurring an
additional charge such as this in the foreseeable future.

Interest Expense

          Net interest expense increased 4.3% to $777 in 1996 compared to $745
in 1995.

Provision for Income Taxes

          The provision/(benefit) for income taxes for 1996 and 1995 are $840
and ($417), respectively.  The tax benefit arising from the loss in 1995 was
less than the amount which results from applying the federal statutory rate to
the loss primarily because of foreign losses for which no tax benefit was
currently available.  The provision in 1996 is higher than the amount which
results from applying the federal statutory rate to income primarily because of
the amortization of non-deductible goodwill and state taxes.

          The Company has recognized for financial reporting purposes deferred
tax assets which consist primarily of a tax net operating loss carryforward.
These deferred tax assets are expected to be realized upon the reversal of
existing taxable temporary differences.

Net Income

          Net income (loss) for the periods ending December 31, 1996 and 1995
were $808 and ($1,669), respectively.  The Company's net income for the period
ended December 31, 1995 was materially impacted by the non-recurring unusual
item discussed previously.  There were no such non-recurring items in 1996.

LIQUIDITY AND CAPITAL RESOURCES

          As of December 31, 1997, working capital was $3,266, an increase of
$3,477 from December 31, 1996.  The increase in working capital is due primarily
to the refinancing of  $3,000 of subordinated debt and $1,203 of deferred
interest that were classified as current liabilities in 1996.  The $1,203
repayment of deferred interest was the principal reason for the Company having
generated less cash from operations in 1997 than 1996.  The cash generated from
operations in 1997 was $2,876 as compared to $3,392 in 1996.

          Cash used in investing activities for 1997 was $2,375, comprised of
$1,382 in payment for the various acquisitions and $1,011 in capital
expenditures.

          In 1997, the Company increased net borrowings from its senior lender
by $1,921.  A portion of these funds was used to supplement cash generated from
operations to repay $3,000 of subordinated debt and $1,203 of deferred interest,
to repay principal under capital lease arrangements of $240, and to finance the
acquisitions noted previously.

          In March of 1997, the Company negotiated a $15,000 senior debt
facility to be used for acquisitions, capital expenditures, and working capital.
The facility is comprised of a revolving credit line of $9,000 carrying an
interest rate of the bank's designated base rate (the "Base Rate") plus 25 basis
points and five year term notes of $6,000 of which (i.) one-third carries a
fixed interest rate of 10.25%; (ii.) one-third carries a fixed interest rate of
10.00%; and (iii.) one-third carries a variable rate of the Base Rate plus one
hundred and fifty basis points. In conjunction with the purchase of ProTel on
January 6, 1998, the Company's senior lender issued an additional five-year note
for $7,500. This note carries an interest rate of LIBOR plus 275 basis points or
the Base Rate plus 75 basis points. The agreement is for three years from the
date of the amendment and is secured by substantially all of the assets of the
Company. The Company believes that its current sources of liquidity and capital
will be sufficient to fund its long-term obligations and working capital needs
for the foreseeable future.

 
INFLATION AND FOREIGN CURRENCY EXCHANGE

          Inflation has not had a significant impact on the Company's operating
results to date, nor does the Company expect it to have a significant impact
through 1997.  As the Company continues to expand its international operations,
exposures to gains and losses from foreign currency fluctuations will increase.
The Company may choose to limit such exposure by the purchase of forward foreign
exchange contracts.

                                      -17-

IMPACT OF YEAR 2000

          The year 2000 issue is the result of computer programs being written
using two digits rather than four to define the year.  Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000.  This could result in a system
failure or miscalculation causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities.

          The Company has taken steps in recent years to ensure that all new
purchased software is year 2000 compliant.  A recently completed internal study
by the Company estimates approximately $250 will be needed to modify or replace
its existing software in order to alleviate the year 2000 issue.  The Company
estimates that by the end of 1998 all of its financial and operational computer
systems will be year 2000 compliant.

                         Report of Independent Auditors



The Board of Directors and Stockholders
Opinion Research Corporation

We have audited the accompanying consolidated balance sheets of Opinion Research
Corporation and Subsidiaries as of December 31, 1997 and 1996, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended December 31, 1997.  Our audits also
included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and schedule are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Opinion
Research Corporation and Subsidiaries at December 31, 1997 and 1996, and the
consolidated 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.  Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS AND BASIS OF PRESENTATION

Opinion Research Corporation and Subsidiaries (the Company, ORC), which was
founded in 1938, provides market research, marketing services, and business
information services.  The Company offers a variety of products and services for
clients in the North American, European, Asian, and Latin American markets.  The
Company offers such services as customer satisfaction, market demand and
forecasting, corporate image, competitive positioning, and telemarketing.  Some
products such as business panels and shared-cost programs are marketed
independently as well as used by the Company to deliver the above listed
services.  The Company operates in one industry segment.

The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries.  All intercompany transactions are eliminated
upon consolidation.

REVENUE RECOGNITION

Revenues from professional services are recognized at the time services are
performed on a percentage of completion basis.  Invoices to clients are
generated in accordance with the terms of the applicable contract, which are not
directly related to the performance of services.  Unbilled services are
classified as a current asset.  Advanced billings from clients in excess of
revenue earned are classified as a current liability.  The Company grants credit
primarily to large public companies and performs periodic credit evaluations of
its clients' financial condition.  The Company does not generally require
collateral.  Credit losses relating to clients consistently have been within
management's expectations.  As of December 31, 1997, two clients constituted 27%
of net accounts receivable.  These clients accounted for 22% of the revenues for
the year ended December 31, 1997.  As of December 31, 1996, two clients
constituted 21% of net accounts receivable and accounted for 29% of revenues for
the year ended December 31, 1996.  At December 31, 1995, one client constituted
33% of net accounts receivable.  Combined revenues for this client accounted for
22% of the Company's revenues for the year ended December 31, 1995.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and  liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

The Company considers as cash equivalents all highly liquid debt instruments
with an original maturity of three months or less when purchased.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost.  Depreciation is provided using the
straight-line method over the estimated useful lives of the related assets (3-10
years).  Leasehold improvements are amortized using the straight-line method
over their estimated useful lives or the remaining life of the lease, whichever
is shorter.

IMPAIRMENT OF LONG-LIVED ASSETS

The Company records impairment losses on long-lived assets used in operations or
expected to be disposed when events and circumstances indicate that the assets
might be impaired and the undiscounted cash flows estimated to be generated by
those assets are less than the carrying amounts of those assets (see Note 12).

CAPITALIZED PRODUCTION COSTS

The costs of producing the Company's standardized computer models are
capitalized and amortized using the straight-line method over three years or the
estimated remaining periods for which the models provide future economic
benefits, whichever is shorter.  The models are computer software which are
marketed and sold by the Company as separate products, along with research and
business information services.  Capitalization of costs begins upon the
establishment of technological feasibility.  The establishment of technological
feasibility and the ongoing assessment of recoverability of capitalized costs
require considerable judgment by management with respect to certain factors
including anticipated future gross revenues, estimated economic life and changes
in technology.  These factors are considered on a product-by-product basis.
Capitalized production costs were 0, $442, and $32 for the years ended December
31, 1997, 1996 and 1995, respectively.  The amortization expense of capitalized
production costs for these same periods was $371, $226, and $683, respectively.
During 1995, the Company recorded a pre-tax write-down of capitalized production
costs of $1,958 (see Note 12).

FOREIGN OPERATIONS

The functional currency for the Company's UK subsidiaries is the British Pound.
The functional currencies for Korea, Taiwan and Mexico are the Korean Won, the
New Taiwan Dollar, and the Mexican Peso.  The translation into U.S. dollars is
performed for assets and liabilities using the exchange rate in effect at the
balance sheet date and for revenue and expense accounts using a monthly average
exchange rate during the period.  Translation adjustments are shown as a
separate component of shareholder's equity.  Combined revenue, assets and other
financial information for foreign operations are as follows:

STOCK-BASED COMPENSATION

As permitted by FASB Statement No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123), the Company has elected to follow Accounting Principal
Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25) and
related interpretations in accounting for its employee option plans.  Under APB
25, no compensation expense is recognized at the time of option grant if the
exercise price of the Company's employee stock option equals or exceeds the fair
market value of the underlying common stock on the date of grant.

INCOME TAXES

The Company files a consolidated federal income tax return.  Separate income tax
returns are filed for foreign, state, and local income taxes.

EARNINGS PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share. Statement 128 replaced the calculation of primary and fully
diluted earnings per share with basic and diluted earnings per share.  Unlike
primary earnings per share, basic earnings per share excludes any dilutive
effects of options, warrants and convertible securities.  Diluted earnings per
share is very similar to the previously reported fully diluted earnings per
share.  All earnings per share amounts for all periods have been presented, and
where appropriate, restated to conform to the Statement 128 requirements.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income," and SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information."  The Company is required to adopt the
provisions of these Statements in fiscal year 1998.  SFAS No. 130 establishes
standards for reporting and display of comprehensive income and its components
in a primary financial statement.  The Company is currently evaluating the
reporting formats recommended under this Statement.  SFAS No. 131 establishes a
new method by which companies will report operating segment information.  This
method is based on the manner in which management organizes the segments within
a company for making operating decisions and assessing performance.  The Company
continues to evaluate the provisions of SFAS No. 131 and, upon adoption, the
Company may report operating segments.

2.  ACQUISITIONS

On April 29, 1994 the Company purchased the stock of Strategic Research and
Consulting, Inc., (SRC), an Ohio corporation, for a price of $3,000.  The
acquisition was accounted for as a purchase and accordingly, the purchase price
was allocated to the assets acquired and liabilities assumed. During 1995, cash
payments totaling $891 were made to the previous owners of SRC as part of the
purchase price which was contingent upon achieving specific performance
criteria.  The additional consideration is recorded as goodwill and is being
amortized over the 24 years remaining on the original goodwill.  Based on 1995
operating performance, a second payment of $667 was made to the principals of
Strategic Research and Consulting, Inc. during 1996.  This payment consisted of
a cash payment of $426 and the issuance of stock valued at $241.  This payment
has been recorded as goodwill and is being amortized over the 23 years remaining
on the original goodwill.  During 1997, a final cash payment of $171 was made
and recorded as goodwill and is being amortized over 22 years.

2.  ACQUISITIONS (CONTINUED)

During 1996, the Company created GSR/SIA, Limited, to purchase the assets of a
division of an information technology company.  This operating company is a
wholly owned subsidiary of ORC Holdings, Limited, a holding company created in
1996 to hold the shares of all the Company's U.K. holdings.  To that end, the
shares of Gordon Simmons Research Group were exchanged by the Company for shares
in ORC Holdings, Limited.  Also during 1996, the Company purchased the stock of
a Chicago based market research company that now serves as the Healthcare
Practice for the Company.

In 1997 the Company completed a stock purchase of a company in Korea and the
asset purchase of companies in Taiwan and Mexico.  Additionally, Gordon Simmons
Research Group was renamed ORC International, Limited, into which GSR/SIA,
Limited, was merged.

The Company has fully utilized its U.S. federal tax net operating loss
carryforwards at December 31, 1997.  At December 31, 1997 and 1996, unremitted
earnings of foreign subsidiaries were approximately $424 and $170, respectively.
Since it is the Company's intention to indefinitely reinvest these earnings, no
U.S. taxes have been provided.  Determination of the amount of unrecognized
deferred tax liability on these unremitted earnings is not practicable.

At December 31, 1997, the Company had a credit facility with a U.S. bank
totaling $15 million:  $9 million of revolving credit and $6 million in three,
five year notes.

As of December 31, 1997, the Company had outstanding $990 on the revolving
credit facility and $5,351 remaining on the term loans.  The revolving credit
facility carries an interest rate of the bank's designated base rate ("Base
Rate") (8.5% at December 31, 1997) plus 25 basis points.  Of the outstanding
term loans, 2/3 carry fixed interest rates of 10.25% and 10%, respectively.  The
remaining 1/3 carries an interest rate of the Base Rate plus one hundred and
fifty basis points.  Payments of interest only were required on these notes for
the first six months.  The weighted average interest rate on short term
borrowings at December 31, 1997 and 1996, were 9.49% and 8.98%, respectively.
The interest rates on the revolving credit facility and on one of the notes are
based on current market rates.  The rates on the remaining two notes were fixed
based on the bank's designated prime rate which has remained unchanged since the
issuance of the notes.  Consequently, the carrying value of the amounts due
under the credit facility approximates their fair value at December 31, 1997.

On August 13, 1993, the Company issued a subordinated 10% convertible note for
$3,000.  The $3,000 in principal and $1,203 of deferred interest were repaid
from the above mentioned credit facility in May 1997.

On January 6, 1998, the credit facility was extended by the Company's senior
lender to $21 million. An additional term loan was issued for $7.5 million
carrying an interest rate of the Base Rate plus

75 basis points or LIBOR plus 275 basis points.  The proceeds from this
additional note, as well as drawings on the revolving credit facility, were used
for the purchase of Pro Tel Marketing, Inc. (see Note 14).

Aggregate maturities of debt for the years ending December 31, inclusive of the
term loan discussed above, are as follows:

The Company paid interest of $679, $379, and $445 during the years ended
December 31, 1997, 1996, and 1995, respectively.  Also during 1997, the Company
paid $1,203 of deferred interest associated with the repayment of its
subordinated debt.

7.  PENSION

The Company maintains a defined contribution pension and profit sharing plan
covering substantially all employees.  Employees may contribute from 1% to 15%
of their annual salary, up to the maximum allowable under the Internal Revenue
Code.  The Board of Directors may elect to match employees' contributions or
contribute to the profit sharing plan.  Plan assets include 310,625 and 317,563
shares of common stock of the Company at December 31, 1997 and 1996,
respectively.  The Company contributed $104,  $75, and $65 to the plan in 1997,
1996, and 1995, respectively.

</TABLE>

Rent expense under operating leases was $2,178, $1,480, and $1,641, for the
years ended December 31, 1997, 1996 and 1995, respectively.  Real estate taxes,
insurance and maintenance expenses generally are obligations of the Company and,
accordingly, are not included as part of rental payments.  It is expected that,
in the normal course of business, leases that expire will be renewed or replaced
by leases on similar properties.

9.  STOCKHOLDERS' EQUITY

On May 8, 1995, the Board of Directors authorized the Company to buy back up to
500,000 shares of the Company's common stock. During the fourth quarter of 1995,
the Company repurchased 34,625 shares at a cost of $207. During 1996 the Company
repurchased 102,182 shares at a cost of $580. Also, during 1996, 48,949 shares
valued at $241 were issued to the three senior principals of SRC (see Note 2).
In December 1997, the Company sold 50,000 shares to a senior executive of the
Company for $269, the fair market value at the time of the transaction.

10.  STOCK OPTIONS

The 1994 Stock Incentive Plan provided for the grant of up to 350,000 options to
purchase common stock to directors and key employees of the Company.  No
employee could be granted options to acquire more than 100,000 shares of Company
common stock in any one calendar year.  The options granted under the 1994 plan
had an exercise price that was at least equal to the fair market value of the
stock on the grant date and were exercisable for seven years.  Options granted
under this plan vested equally over a period of three years.  The plan
terminates on April 25, 2004.

The 1993 Stock Incentive Plan provided for the grant of up to 375,000 options to
purchase common stock to directors and key employees of the Company.  The
exercise price of options granted to employees under this plan was at least
equal to the fair market value of the stock on the date of grant.  These options
vested equally over a three year period.  The plan terminates in August 2003.
As amended in 1996, each Non-employee Director on the date of the Annual Meeting
of Stockholders is automatically granted options to acquire the "formula number"
of shares of common stock.  The option exercise price for these options will be
equal to the fair market value of the underlying shares on the date of the
grant.  The options granted under this provision will be non-qualified stock
options.  The Non-employee Directors' options will become exercisable on the

10.  STOCK OPTIONS (CONTINUED)

first anniversary of the date of grant provided the Non-employee Director is a
member of the Board of Directors on that date.  The  "formula number" for 1997
and 1996 was 15,000 shares for those Non-employee Directors who have served as a
member of the Board of Directors for a period of three full years or more, and
5,000 shares for all other Non-employee Directors.

Non-employee Directors' options terminate seven years from the date of grant or
90 days after the optionee ceases to serve as a member of the Board of Directors
for any reason.  Any options of a Non-employee Director that are not exercisable
when he or she ceases to serve as a member of the Board of Directors will
terminate as of the termination of the Non-employee Director's service on the
Board of Directors.

On June 17, 1997 the shareholders of the Company approved the merger of the 1993
and 1994 Stock Incentive Plans into the 1997 Stock Incentive Plan.  This merger
was undertaken in order to simplify administration and record keeping otherwise
required in operating the plans separately.  The 1997 Stock Incentive Plan was
also amended to increase the number of shares available for grant from 725,000
to 875,000.  The 1997 Stock Incentive Plan terminates on April 16, 2007.  Stock
option transactions for the 1997 Stock Incentive Plan (and its predecessors)
were as follows:

10.  STOCK OPTIONS (CONTINUED)

Included above in the 1997 figures are 307,706 options that were issued in 1993
and 1994, cancelled in December 1997, and reissued in December 1997.  The
reissued options retained all of the original attributes except for expiration
dates which are six years from the date of grant for options initially granted
in 1993 and seven years for those options originally granted in 1994.  All
reissued options have an exercise price equal to or greater than the market
value of the stock on the date of grant.

Additionally, in December 1997, 200,000 non-plan options were granted to three
senior executives. These non-plan options were issued with an exercise price
equal to the market value of the stock at the date of grant.  These options have
a vesting period of three years and a life of seven years.  These options are
included in the previously presented option table.

Options exercisable at December 31, 1997, 1996 and 1995 were 533,791, 386,709,
and 305,536, respectively.  Exercise prices for options outstanding as of
December 31, 1997 for the plan ranged from $3.63 to $8.38 per share.  The
weighted average remaining term of the outstanding options is 5.76 years.

During 1995 the Board of Directors voted to reduce the exercise price of the
options granted prior to 1994 from $8.00 to $5.875 per share.

In accordance with the provisions of SFAS No. 123, the Company applies APB 25
and related interpretations in accounting for its stock option plans and,
accordingly, does not recognize compensation expense.  If the Company had
elected to recognize compensation expense based on the fair value of the options
granted at grant date as prescribed by SFAS No. 123, net income (loss) and
earnings (loss) per share would have been reduced to the pro forma amounts
indicated in the table below:

12.  UNUSUAL CHARGE

During the second quarter of 1995, the Company announced a plan to restructure
and consolidate operations, concentrate resources, and better position itself to
achieve its strategic growth objectives.  This plan resulted in a pre-tax charge
of $3,489 in 1995.  This charge included a $1,958 write-down of capitalized
production costs; $178 for the disposal of obsolete fixed assets; $460 of
impaired intangible assets associated with previous acquisitions; $380 in
severance costs; $414 provision for the abandonment of leases; and other
miscellaneous charges of $99.

13.  SPLIT-DOLLAR LIFE INSURANCE

During 1995, the Company entered into certain agreements with trusts established
in the names of two officers of the Company.  Under these agreements, the
Company pays certain premiums on life insurance policies on the officers, to
which the trusts are the beneficiaries.  The Company has been assigned certain
rights to the assets of the trusts as collateral for the premiums paid on these
life insurance policies.  The amounts paid by the Company for the premiums on
these policies, an aggregate of $292 and $178 at December 31, 1997 and 1996,
respectively, are included in other assets in the accompanying consolidated
balance sheets.  In the event the policies are terminated, the officers have
guaranteed the repayment of the amounts due from their respective trusts, and
have pledged certain of their personal assets to the Company to collateralize
such guarantees.

14.  SUBSEQUENT EVENTS

Pursuant to an Asset Purchase Agreement dated January 6, 1998, ORC ProTel
("ProTel"), a newly created subsidiary of the Company, purchased certain assets
(not including cash or accounts receivable) and assumed certain liabilities of
Pro Tel Marketing, Inc.  The acquisition was accounted for as a purchase and
accordingly, the purchase price was allocated to the assets acquired and
liabilities assumed.  The purchase price was comprised of a $10,000 cash payment
and 400,000 options to purchase common shares of the Company's stock, with the
provision that such options may, at the option of the holders, be returned to
the Company for cash payment of $2,000 on the second anniversary of the closing.
The fair value of these options was $1,691 at the acquisition date.  The fair
value of the assets acquired and liabilities assumed was $632 and $143,
respectively. The Company incurred $543 of costs related to the acquisition.
Identifiable intangible assets valued at $1,250 are being amortized using the
straight-line method over a period of five years.  The excess consideration paid
over the estimated fair value of net assets acquired in the amount of $10,495
has been recorded as Goodwill to be amortized using the straight-line method
over a period of fifteen years. In addition, over the next three years, the
sellers may earn up to an additional $10,000 of cash payments, contingent upon
ProTel achieving certain future targets for revenues and earnings before
interest, income taxes, depreciation, and amortization.

incentive to certain Directors of the Company who are not employees of the

Directors may be granted Options under Section 8 of the Plan notwithstanding the
automatic grant of Options to such Non-employee Directors under Section 9.

          6.   Shares Subject to Plan.  The aggregate maximum number of Shares
               ----------------------                                         
for which Options and Awards may be granted pursuant to the Plan (taking into
account all Options and Awards granted under the 1993 Plan and the 1994 Plan
prior to their merger and restatement set forth herein) is eight hundred seventy
five thousand (875,000), subject to adjustment as provided in Section 11 of the
Plan.  The Shares shall be issued from authorized and unissued Common Stock or
Common Stock held in or hereafter acquired for the treasury of the Company.  If
an Option terminates or expires without having been fully exercised for any
reason, or if Shares granted pursuant to an Award are forfeited for any reason,
such Shares may again be the subject of one or more Options or Awards granted
pursuant to the Plan.

          7.   Term of the Plan.  This amended and restated Plan is effective as
               ----------------                                                 
of April 16, 1997, the date on which it was adopted by the Board of Directors,
subject to approval prior to April 16, 1998 by a majority of the votes cast by
stockholders entitled to vote, or by a method and in a degree that would be
treated as adequate under applicable state law in the case of an action
requiring shareholder approval.  No Option or Award may be granted under the
Plan after April 16, 2007.  If the Plan is not so approved on or before April
__, 1997, all Options granted under the Plan as amended and restated shall be
null and void, except to the extent such options could have been granted under
the 1993 Plan or the 1994 Plan as in effect without regard to this merger and
restatement.

          8.   Option Documents and Terms.  Each Option granted under the Plan
               --------------------------                                     
shall be a Non-qualified Stock Option unless the  Option shall be specifically
designated at the time of 

                                       7
<PAGE>
 
grant to be an ISO for federal income tax purposes. If any Option designated an
ISO is determined for any reason not to qualify as an incentive stock option
within the meaning of Section 422 of the Code, such Option shall be treated as a
Non-qualified Stock Option for all purposes under the provisions of the Plan.
Options granted pursuant to the Plan shall be evidenced by the Option Documents
in such form as the Committee shall from time to time approve, which Option
Documents shall comply with and be subject to the following terms and conditions
and such other terms and conditions as the Committee shall from time to time
require which are not inconsistent with the terms of the Plan.

          (a) Number of Option Shares.  Each Option Document shall state the
              -----------------------                                       
number of Shares to which it pertains.  An Optionee may receive more than one
Option, which may include Options which are intended to be ISO's and Options
which are not intended to be ISO's, but only on the terms and subject to the
conditions and restrictions of the Plan.  Notwithstanding anything to the
contrary contained herein, no employee shall be granted Options to acquire more
than one hundred thousand (100,000) Shares during any one calendar year.

          (b) Option Price.  Each Option Document shall state the Option Price
              ------------                                                    
which, for a Non-qualified Stock Option, may be less than, equal to, or greater
than the Fair Market Value of the Shares on the date the Option is granted and,
for an ISO, shall be at least 100% of the Fair Market Value of the Shares on the
date the Option is granted as determined by the Committee in accordance with
this Subsection 8(b); provided, however, that if an ISO is granted to an
Optionee who then owns, directly or by attribution under Section 424(d) of the
Code, shares possessing more than ten percent of the total combined voting power
of all classes 

                                       8
<PAGE>
 
of stock of the Company or an Affiliate, then the Option Price shall be at least
110% of the Fair Market Value of the Shares on the date the Option is granted.
If the Common Stock is traded in a public market, then the Fair Market Value per
Share shall be, if the Common Stock is listed on a national securities exchange
or included in the NASDAQ National Market System, the last reported sale price
thereof on the relevant date, or, if the Common Stock is not so listed or
included, the mean between the last reported "bid" and "asked" prices thereof on
the relevant date, as reported on NASDAQ or, if not so reported, as reported by
the National Daily Quotation Bureau, Inc. or as reported in a customary
financial reporting service, as applicable and as the Committee determines.

          (c) Exercise.  No Option shall be deemed to have been exercised prior
              --------                                                         
to the receipt by the Company of written notice of such exercise and of payment
in full of the Option Price for the Shares to be purchased.  Each such notice
shall specify the number of Shares to be purchased and shall (unless the Shares
are covered by a then current registration statement or a Notification under
Regulation A under the Securities Act of 1933, as amended (the "Act")), contain
the Optionee's acknowledgment in form and substance satisfactory to the Company
that (a) such Shares are being purchased for investment and not for distribution
or resale (other than a distribution or resale which, in the opinion of counsel
satisfactory to the Company, may be made without violating the registration
provisions of the Act), (b) the Optionee has been advised and understands that
(i) the Shares have not been registered under the Act and are "restricted
securities" within the meaning of Rule 144 under the Act and are subject to
restrictions on transfer and (ii) the Company is under no obligation to register
the Shares under the Act or to take any action which would make available to the
Optionee any exemption 

                                       9
<PAGE>
 
from such registration, (c) such Shares may not be transferred without
compliance with all applicable federal and state securities laws, and (d) an
appropriate legend referring to the foregoing restrictions on transfer and any
other restrictions imposed under the Option Documents may be endorsed on the
certificates. Notwithstanding the foregoing, if the Company determines that
issuance of Shares should be delayed pending (A) registration under federal or
state securities laws, (B) the receipt of an opinion of counsel satisfactory to
the Company that an appropriate exemption from such registration is available,
(C) the listing or inclusion of the Shares on any securities exchange or an
automated quotation system or (D) the consent or approval of any governmental
regulatory body whose consent or approval is necessary in connection with the
issuance of such Shares, the Company may defer exercise of any Option granted
hereunder until any of the events described in this sentence has occurred.

          (d) Medium of Payment.  An Optionee shall pay for Shares (i) in cash,
              -----------------                                                
(ii) by certified or cashier's check payable to the order of the Company, or
(iii) by such other mode of payment as the Committee may approve, including
payment through a broker in accordance with procedures permitted by Regulation T
of the Federal Reserve Board.  Furthermore, the Committee may provide in an
Option Document that payment may be made in whole or in part in shares of the
Company's Common Stock held by the Optionee.  If payment is made in whole or in
part in shares of Common Stock, then the Optionee shall deliver to the Company
certificates registered in the name of such Optionee representing the shares of
Common Stock owned by such Optionee, free of all liens, claims and encumbrances
of every kind and having an aggregate Fair Market Value on the date of delivery
that is at least as great as the Option Price of the Shares (or relevant portion
thereof) with respect to which such Option is 

                                       10
<PAGE>
 
to be exercised by payment in shares of Common Stock, the stock certificate
issued to the Optionee shall represent (i) the Shares in respect of which
payment is made, and (ii) such excess number of shares of Common Stock.
Notwithstanding the foregoing, the Committee may impose from time to time such
limitations and prohibitions on the use of shares of Common Stock to exercise an
Option as it deems appropriate.

               (e)  Termination of Options.
                    ---------------------- 
                    (i)  No Option shall be exercisable after the  first to
occur of the following:

                           (A) Expiration of the Option term specified in the
Option Document, which, in the case of an ISO, shall not occur after (1) ten
years from the date of grant, or (2) five years from the date of grant of an ISO
if the Optionee on the date of grant owns, directly or by attribution under
Section 424(d) of the Code, shares possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or of an
Affiliate;

                           (B) Expiration of two years from the date such 
employment or service with the Company or its Affiliates terminates due to the
Optionee's death or one year

                                       11
<PAGE>
 
from the date such employment or service with the Company or its Affiliates
terminates due to the Optionee's Disability;

                           (C) A finding by the Committee, after full
consideration of the facts presented on behalf of both the Company and the
Optionee, that the Optionee has materially breached his or her employment or
service contract with the Company or an Affiliate, or has been engaged in
disloyalty to the Company or an Affiliate, including, without limitation, fraud,
embezzlement, theft, commission of a felony or proven dishonesty in the course
of his or her employment or service, or has disclosed trade secrets or
confidential information of the Company or an Affiliate. In such event, in
addition to immediate termination of the Option, the Optionee shall
automatically forfeit all Shares for which the Company has not yet delivered the
share certificates upon refund by the Company of the Option Price.
Notwithstanding anything herein to the contrary, the Company may withhold
delivery of share certificates pending the resolution of any inquiry that could
lead to a finding resulting in a forfeiture;

                           (D) The date, if any, set by the Board of Directors
as an accelerated expiration date in the event of the liquidation or dissolution
of the Company; or
                           (E) The occurrence of such other event as may be
specified in the Option Document at the discretion of the Committee.

                   (ii)    Notwithstanding the foregoing, the Committee may 
extend the period during which all or any portion of an Option may be exercised
to a date no later than the Option term specified in the Option Document
pursuant to Subsection 8(e)(i)(A), provided that any change pursuant to this
Subsection 8(e)(ii) which would cause an ISO to become a Non-qualified Stock
Option may be made only with the consent of the Optionee. The terms of

                                       12
<PAGE>
 
an executive severance agreement or other agreement between the Company and an
Optionee, approved by the Committee, whether entered into prior or subsequent to
the grant of an Option, which provide for Option exercise dates later than those
set forth in Subsection 8(e)(i) but permitted by this Subsection 8(e)(ii) shall
be deemed to be Option terms approved by the Committee and consented to by the
Optionee.

                   (iii)   Except as may otherwise be provided in an Option
Document, no Option shall be exercisable after the date the Optionee's
employment or service with the Company or its Affiliates terminates to any
extent greater than such Option could have been exercised immediately prior to
the date such employment or service terminated.

             (f)   Transfers. No Option granted under the Plan may be 
                   ---------
transferred, except by will or by the laws of descent and distribution. During
the lifetime of the person to whom an Option is granted, such Option may be
exercised only by such person. Notwithstanding the foregoing, a Non-qualified
Stock Option may be transferred pursuant to the terms of a "qualified domestic
relations order," within the meaning of Sections 401(a)(13) and 414(p) of the
Code or within the meaning of Title I of the Employee Retirement Income Security
Act of 1974, as amended.

             (g)   Limitation on ISO Grants.  In no event shall the aggregate 
                   ------------------------
Fair Market Value of the Shares of Common Stock (determined at the time the ISO
is granted) with respect to which incentive stock options under all incentive
stock option plans of the Company or its Affiliates are exercisable for the
first time by the Optionee during any calendar year exceed $100,000, or such
other amount as may be specified in lieu of the $100,000 limit in applicable
provisions of the Code.

                                       13
<PAGE>
 
             (h)   Other Provisions.  Subject to the provisions of the Plan, the
                   ----------------                                             
Option Documents shall contain such other provisions including, without
limitation, provisions authorizing the Committee to accelerate the
exercisability of all or any portion of an Option granted pursuant to the Plan,
additional restrictions upon the exercise of the Option or additional
limitations upon the term of the Option, as the Committee shall deem advisable.

             (i)   Amendment.  Subject to the provisions of the Plan, the 
                   ---------
Committee shall have the right to amend Option Documents issued to an Optionee,
subject to the Optionee's consent if such amendment is not favorable to the
Optionee, except that the consent of the Optionee shall not be required for any
amendment made pursuant to Subsection 8(e)(i)(D) or Section 10 of the Plan, as
applicable.

        9.   Special Provisions Relating to Grants of Options to Non-employee
             ----------------------------------------------------------------
Directors.  Options granted pursuant to this Section 9 shall be granted only to
- ---------                                                                      
Non-employee Directors.  Options granted under this Section 9 shall be granted,
without any further action by the Committee, in accordance with the terms and
conditions set forth in this Section 9, and shall be evidenced by Option

grant of his or her Option under this Section 9.

              (b)  Termination of Options Granted Pursuant to Section 9.  All
                   ----------------------------------------------------

that payment may be made in whole or in part in Shares of Company Common Stock);
Subsection 8(f); and Subsection 8(i).

         10. Change of Control.  In the event of a Change of Control, the
             -----------------

to the Options and Awards outstanding (other than Options granted pursuant to
Section 9), including, without limitation, accelerating the expiration or
termination date in the respective Option Documents to a date no earlier than
thirty (30) days after notice of such acceleration is given to the Optionees.
In addition to the foregoing, in the event of a Change of Control, Options
granted pursuant to the Plan and held by Optionees who are employees or members
of the Board of Directors at the time of a Change of Control shall become
immediately exercisable in full and the restrictions applicable to Restricted
Stock awarded to Awardees who are employees or members of the Board of Directors
at the time of a Change of Control shall immediately lapse and the Restricted
Stock held by the Company shall be delivered to the Grantees.  Any amendment to
this Section 

                                       16
<PAGE>
 
10 which diminishes the rights of Optionees shall not be effective with respect

either case, a merger or consolidation of the Company in which holders of shares
of the Company's Common Stock immediately prior to the merger or consolidation
will have at least a majority of the ownership of common stock of the surviving
corporation (and, if one class of common stock is not the only class of voting
securities entitled to vote on the election of directors of the surviving
corporation, a majority of the voting power of the surviving corporation's
voting securities) immediately after the merger or consolidation, which common
stock (and, if applicable, voting securities) is to be held in the same
proportion as such holders' ownership of Common Stock of the Company immediately
before the merger or consolidation, or (iv) the date any entity, person or
group, within the meaning of Section 13(d)(3) or Section 14(d)(2) of the

beginning of such two (2) year period was approved by a vote of at least two-
thirds of the directors then still in office who were directors at the beginning
of such period.

          11.  Adjustments on Changes in Capitalization.  The aggregate number

hereunder, the number and class or classes of shares covered by each outstanding
Option and the Option Price thereof shall be appropriately adjusted in the event
of a stock dividend, stock split, recapitalization or other change in the number
or class of issued and outstanding equity securities of the Company resulting
from a subdivision or consolidation of the Common Stock and/or, if appropriate,
other outstanding equity securities or a recapitalization or other capital
adjustment (not including the issuance of Common Stock on the conversion of
other securities of the Company which are convertible into Common Stock)

discretion, shorten or waive any term or condition with respect to all or any
portion of any Award.

               (a) Number of Shares.  Each Award Agreement shall state the

in cash, (ii) by certified check payable to the order of the Company, or (iii)
by such other mode of payment as the Committee may approve.

               (c) Restrictions on Transfer and Forfeitures.  A stock

the expiration or termination of any period designated by the Committee
("Restricted Period") and the satisfaction of any other conditions prescribed by
the Committee; (ii) all distributions with respect to the Restricted Stock other

right to sell, exchange, transfer, pledge, hypothecate or otherwise dispose of
any of the Restricted Stock or distributions (other than cash dividends) with
respect thereto; and (iv) all of the Restricted Stock shall be forfeited and all
rights of the Awardee with respect to such Restricted Stock shall terminate
without further obligation on the part of the Company unless the Awardee has
remained an employee of the Company, any of its affiliates or any combination
thereof until the expiration or termination of the Restricted Period and the
satisfaction of any other conditions prescribed by the Committee applicable to
such Restricted Stock. Upon the forfeiture of any Restricted Stock, such
forfeited shares shall be transferred to the Company without further action by
the Awardee.

          (d) Lapse of Restrictions.  Upon the expiration or termination of the
              ---------------------                                            
Restricted Period and the satisfaction of any other conditions prescribed by the
Committee as provided for in the Plan, the restrictions applicable to the
Restricted Stock shall lapse and a stock certificate for the number of shares of
Common Stock with respect to which the restrictions have lapsed shall be
delivered, free of all such restrictions, except any that may be imposed by law,
to 

                                       20
<PAGE>
 
the Awardee or the beneficiary or estate, as the case may be. The Company shall
not be required to deliver any fractional share of Common Stock but will pay, in
lieu thereof, the fair market value (determined as of the date the restrictions
lapse) of such fractional share to the Awardee or the Awardee's beneficiary or
estate, as the case may be. The Award may provide for the lapse of restrictions
on transfer and forfeiture conditions in installments.

          (e) Section 83(b) Elections.  An Awardee shall agree as a condition to
              -----------------------                                           
receipt of any Award under the Plan, to make an election with the Internal
Revenue Service under Section 83(b) of the Code to include the fair market value
of any Restricted Stock in gross income while they are still subject to
restrictions ("83(b) Election"), only after obtaining the written consent of the
Company to such Election.  An Awardee who files an 83(b) Election shall promptly
furnish the Company with a copy of such Election together with the amount of any
federal, state, local or other taxes required to be withheld to enable the
Company to claim an income tax deduction with respect to such Election.

          (f) Breach of Contract or Disloyalty.  Upon a finding by the
              --------------------------------                        
Committee, after full consideration of the facts presented on behalf of both the
Company and the Awardee, that the Awardee has breached his or her employment or
service contract with the Company or an Affiliate, or has been engaged in
disloyalty to the Company or an Affiliate, including, without limitation, fraud,
embezzlement, theft, commission of a felony or proven dishonesty in the course
of his or her employment or service, or has disclosed trade secrets or
confidential information of the Company or an Affiliate, Awardee shall
automatically forfeit all Restricted Stock for which (1) the Company has not yet
delivered the Share certificates to the Awardee; (ii) the Restricted Period has
not expired or (iii) any restrictions applicable to the 

                                       21
<PAGE>
 
Restricted Stock have not lapsed. Notwithstanding anything herein to the
contrary, the Company may withhold delivery of Restricted Stock certificates
pending the resolution of any inquiry that could lead to a finding resulting in
a forfeiture.

          (g) Amendment.  Subject to the provisions of the Plan, the Committee
              ---------                                                       
shall have the right to amend Awards issued to an Awardee, subject to the
Awardee's consent if such amendment is not favorable to the Awardee, except that
the consent of the Awardee shall not be required for any amendment made pursuant
to Section 10 of the Plan.

     13.  Amendment of the Plan.  The Board of Directors of the Company may
          ---------------------                                            
amend the Plan from time to time in such manner as it may deem advisable.
Nevertheless, the Board of Directors of the Company may not change the class of
individuals eligible to receive an ISO or increase the maximum number of Shares
as to which Options may be granted without obtaining approval, within twelve
months before or after such action, by vote of a majority  of the votes cast at
a duly called meeting of the stockholders at which a quorum representing a
majority of all outstanding voting stock of the Company is, either in person or
by proxy, present and voting on the matter, or by a method and in a degree that
would be treated as adequate under applicable state law in the case of an action
requiring shareholder approval.  No amendment to the Plan shall adversely affect
any outstanding Option or Award, however, without the consent of the Grantee.

     14.  No Commitment to Retain.  The grant of an Option or Award
          ------------------------                                 
pursuant to the Plan shall not be construed to imply or to constitute evidence
of any agreement, express or implied, on the part of the Company or any
Affiliate to retain the Grantee in the employ of the 

                                       22
<PAGE>
 
Company or an Affiliate and/or as a member of the Company's Board of Directors
or in any other capacity.

          15.  Withholding of Taxes.  Whenever the Company proposes or is
               --------------------                                      
required to deliver or transfer Shares in connection with the exercise of an
Option or Award, the Company shall have the right to (a) require the recipient
to remit or otherwise make available to the Company an amount sufficient to
satisfy any federal, state and/or local withholding tax requirements prior to
the delivery or transfer of any certificate or certificates for such Shares or
(b) take whatever other action it deems necessary to protect its interests with
respect to tax liabilities.  The Company's obligation to make any delivery or
transfer of Shares shall be conditioned on the Optionee's compliance, to the
Company's satisfaction, with any withholding requirement.

          16.  Interpretation.  The Plan is intended to enable transactions
               --------------                                              
under the Plan with respect to directors and officers (within the meaning of
Section 16(a) under the Securities Exchange Act of 1934, as amended) to satisfy
the conditions of Rule 16b-3; to the extent that any provision of the Plan would
cause a conflict with such conditions or would cause the administration of the
Plan as provided in Section 3 to fail to satisfy the conditions of Rule 16b-3,
such provision shall be deemed null and void to the extent permitted by
applicable law.  This section shall not be applicable if no class of the
Company's equity securities is then registered pursuant to Section 12 of the
Securities Exchange Act of 1934, as amended.

SECTION 2. THE LOANS

     2.1  Revolving Credit:
          ----------------   

          (a) Description.  Subject to the terms and conditions of this
              -----------                                              
Agreement, Lender hereby establishes for the benefit of Borrowers a revolving
credit facility (collectively, the "Revolving Credit") which shall include
Advances extended by Lender to or for the benefit of Borrowers from time to time
hereunder.  The aggregate principal amount of unpaid cash Advances, unreimbursed
draws on Letter(s) of Credit plus outstanding and undrawn Letter(s) of Credit
shall not, at any time exceed the lesser of (i) the Maximum Revolving Credit
Amount or (ii) the Borrowing Base.  Subject to such limitation, the outstanding
balance of Advances under the Revolving Credit may fluctuate from time to time,
to be reduced by repayments made by Borrowers, to be increased by future
Advances which may be made by Lender, to or for the benefit of Borrowers, and,
subject to the provisions of Section 8 below, shall be due and payable on the
Revolving Credit Maturity Date.  If the aggregate principal amount of unpaid
cash Advances, unreimbursed draws on Letters of Credit plus outstanding and
undrawn Letter(s) of Credit at any time exceeds the lesser of the Maximum
Revolving Credit Amount or the Borrowing Base (such excess referred to as
"Overadvance"), Borrowers shall immediately repay the Overadvance in full.  Any
outstanding advances under the revolving credit established under the Existing
Loan Agreement shall be deemed an Advance hereunder.

          (b) Revolving Credit Note.  At Closing, Borrowers shall execute and
              ---------------------                                          
deliver their amended and restated promissory note ("Revolving Credit Note") to
Lender for the total principal amount of the Revolving Credit.  The Revolving
Credit Note shall evidence each Borrower's absolute and unconditional obligation
to repay Lender for all Advances made under the Revolving Credit, with interest
as herein and therein provided.  The obligations of Borrowers under the
Revolving Credit and this Agreement shall at all times be joint and several.
The Revolving Credit Note shall be in form and substance satisfactory to Lender
and shall amend and restate (but shall not extinguish the absolute and
unconditional obligation to repay the Indebtedness evidenced by) the Existing
Revolving Credit Note.

          (c) Term.  The term of the Revolving Credit shall expire on the
              ----                                                       
Revolving Credit Maturity Date.  On the Revolving Credit Maturity Date, unless
having been sooner accelerated by Lender pursuant to the terms hereof, all sums
owing under the Revolving Credit shall be due and payable in full; and on and
after the Revolving Credit Maturity Date, Borrowers shall not request and Lender
shall not make any further Advances under the Revolving Credit.
<PAGE>
 
          (d)  Method of Advances.
                ------------------ 

          (i) All Advances requested by Borrowers under the Revolving Credit
must be requested by twelve o'clock (12:00) Noon, Philadelphia time, on the
Business Day such Advance is to be made.  Lender may rely upon any telephone
request made or purported to be made by an Authorized Officer of Opinion (or
such other Person designated to Lender in writing by an Authorized Officer of
Opinion), which request shall be confirmed in writing by an Authorized Officer
of Opinion (or such other Person designated to Lender in writing by such
Authorized Officer).  Such written confirmation may be sent by telecopy or
facsimile transmission on the same day as the request.  Any check presented
against any Borrower's controlled disbursement account with Lender shall be
deemed a written request for an Advance.

          (ii) Upon receiving a request for an Advance in accordance with
subparagraph (i) above, Lender shall make the requested Advance available to
Borrowers by crediting such amount to Borrowers' operating account with Lender
as soon as is reasonably practicable thereafter on the same Business Day the
requested Advance is made.  Any requests for an Advance received after twelve
o'clock (12:00) P.M., Philadelphia Time will be made available, as set forth
above on the next Business Day.

          (e) Commitment Reduction.  Borrowers shall have the right at any time
              --------------------                                             
and from time to time, upon five (5) Business Days prior written notice to
Lender, to permanently reduce, without premium or penalty, the Maximum Revolving
Credit Amount in the minimum amount of Two Million Dollars ($2,000,000.00) and
integral multiples of One Million Dollars ($1,000,000.00) in excess thereof;
provided that Borrowers may not reduce the Maximum Revolving Credit Amount below
the aggregate stated amount of outstanding Letters of Credit plus all
                                                             ----    
outstanding unpaid Reimbursement Obligations with respect to Letters of Credit
unless, at Lender's sole discretion, Borrowers have provided Lender with cash
collateral in an amount reasonably determined by Lender.  Any notice to reduce
the Maximum Revolving Credit Amount pursuant to this Section 2.1(e) shall be
permanent and may not be revoked.  In the event of any such reduction (but
subject to the proviso of the first sentence of this Section 2.1(e)),
outstanding cash Advances in an amount in excess of the Maximum Revolving Credit
Amount, as so reduced, shall be paid on the effective date of such reduction,
with interest accrued on the amount so paid to the date of reduction.

          (a) Establishment Letters of Credit.  As a part of the Revolving

the Borrowing Base), Lender shall make available to Borrowers Letter(s) of
Credit which shall not 
<PAGE>
 
exceed, in the aggregate at any one time outstanding, the L/C Commitment.
Notwithstanding the foregoing, all Letters of Credit shall be in form and
substance reasonably satisfactory to Lender and for purposes reasonably
satisfactory to Lender. No Letter of Credit shall be issued with an expiry date
later than the earlier of (i) three hundred sixty five (365) days from the date
of issuance or (ii) the Revolving Credit Maturity Date. Borrowers shall execute
and deliver to Lender all letter of credit agreements and other documents
reasonably required by Lender for such purposes, all such documents to be in
form and substance reasonably satisfactory to Lender in its sole discretion.

          (b) Existing L/C's.  All Letters of Credit issued by Lender under the
              --------------                                                   
Existing Loan Agreement prior to and undrawn on the Closing Date (the "Existing
L/Cs") shall be part of, to the extent thereof, the L/C Commitment and shall be
deemed to have been issued by Lender as of the Closing Date.  All Existing L/Cs
are listed on Schedule "2.2(b)" attached hereto and made a part hereof.
Borrowers hereby expressly assume all Reimbursement Obligations under, and adopt
all reimbursement agreements with respect to, the Existing L/Cs.

          (c) Reduction to Revolving Credit.  Each Letter of Credit issued from
              -----------------------------                                    
time to time under the Revolving Credit which remains undrawn (and the amounts
of draws on Letters of Credit prior to payment as hereinafter set forth),

Letter of Credit by the beneficiary thereof, Lender shall promptly notify
Borrowers and Borrowers shall immediately reimburse Lender on the day when such
drawing is honored, by either a cash payment by Borrowers, or, in the absence of
such payment by Borrowers, and at Lender's sole discretion, by Lender
automatically making, or having been deemed to have made, (without further
request or approval of Borrowers and irrespective of the existence of a Default
or Event of Default) a cash Advance under the Revolving Credit on such date to
reimburse Lender.  Borrowers' reimbursement obligation for draws under Letters
of Credit along with the obligation to pay L/C Fees shall herein be referred to
collectively as Borrowers' "Reimbursement Obligations".  All of Borrowers'
Reimbursement Obligations hereunder with respect to Letters of Credit shall
apply unconditionally and absolutely to, and shall be joint and several with

under the Letters of Credit 
<PAGE>
 
shall be unconditional and irrevocable and shall be paid strictly in accordance
with the terms of this Agreement under all circumstances including, without
limitation, the following circumstances:

          (i) any lack of validity or enforceability of any Letter of Credit;

          (ii) the existence of any claim, setoff, defense or other right that
Borrowers or any other Person may have at any time against a beneficiary or any
transferee of any Letter of Credit (or any persons or entities for whom any such
beneficiary or transferee may be acting), Lender or any other Person, whether in
connection with this Agreement, the transactions contemplated herein or any
unrelated transaction;

          (iii) any draft, demand, certificate or any other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect;

          (iv) payment by Lender under any Letter of Credit against presentation
of a demand, draft or certificate or other document that does not substantially
comply with the terms of such Letter of Credit unless Lender shall have acted
with willful misconduct or gross negligence in issuing such payment;

          (v) any other circumstance or happening whatsoever that is similar to
any of the foregoing; or

          (vi) the fact that a Default or Event of Default shall have occurred
and be continuing.

Date in applicable law, regulation, rule, decree or regulatory requirement or
any change in the interpretation or application by any Governmental Authority of
any law, regulation, rule, decree or regulatory requirement or (ii) compliance
by Lender with any direction, reasonable request or requirement (whether or not
having the force of law) of any monetary authority or Governmental Authority
including, without limitation, Regulation D of the Board of Governors of the
Federal Reserve System:

          (A) Lender shall be subject to any tax or other levy or charge of any
nature or to any variation thereof (except for changes in the rate of any tax on
the net income of Lender or its applicable lending office) or to any penalty
with respect to the maintenance or fulfillment of its obligations under this
Section 2.2, whether directly or by such being imposed on or suffered by Lender;
<PAGE>
 
          (B) any reserve, deposit or similar requirement is or shall be
applicable, imposed or modified in respect of any Letter of Credit issued by
Lender; or

          (C) there shall be imposed on Lender any other condition regarding
this Section 2.2, any Letter of Credit or any participation therein;

and the result of the foregoing is to directly or indirectly increase the cost
to Lender of issuing, creating, making or maintaining any Letter of Credit, or
to reduce the amount receivable in respect thereof by Lender, then and in any
such case Lender shall, after the additional cost is incurred or the amount
received is reduced, notify Borrowers and Borrowers shall pay on demand such
amounts as may be necessary to compensate Lender for such additional cost or
reduced receipt, together with interest on such amount from the date demanded
until payment in full thereof at a rate per annum equal at all times to the
applicable interest rate under the Revolving Credit.  A certificate signed by an
officer of Lender as to the amount of such increased cost or reduced receipt
showing in reasonable detail the basis for the calculation thereof, submitted to
Borrowers by Lender shall, be prima facie evidence of the amount due and absent
written notice from Borrowers to Lender within thirty (30) days from submission,
be final, conclusive and binding for all purposes.

provided in this Section 2.2, without duplication, Borrowers hereby agree to
protect, indemnify, pay and save Lender harmless from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable attorneys' fees) which Lender may incur or be subject to
as a consequence, direct or indirect, of (A) the issuance of the Letters of
Credit or (B) the failure of Lender to honor a drawing under any Letter of
Credit as a result of any act or omission, whether rightful or wrongful, of any
present or future de jure or de facto government or Governmental Authority (all
                  -------    --------                                          
such acts or omissions herein called "Government Acts").

          (ii)  As between Borrowers and Lender, Borrowers assume all risks of
the acts and omissions of, or misuse of the Letters of Credit issued by Lender
by the respective beneficiaries of such Letters of Credit.  In furtherance and
not in limitation of the foregoing, Lender shall not be responsible: (A) for the
form, validity, sufficiency, accuracy, genuineness or legal effects of any
document submitted by any party in connection with the application for and
issuance of such Letters of Credit, even if it should in fact prove to be in any
or all respects invalid, insufficient, inaccurate, fraudulent or forged; (B) for
the validity or sufficiency of any instrument transferring or 
<PAGE>
 
assigning or purporting to transfer or assign any such Letter of Credit or the
rights or benefits thereunder or proceeds thereof, in whole or in part, that may
prove to be invalid or ineffective for any reason; (C) for failure of the
beneficiary of any such Letter of Credit to comply fully with conditions
required in order to draw upon such Letter of Credit unless pursuant to Lender's
gross negligence or willful misconduct; (D) for errors, omissions, interruptions
or delays in transmission or delivery of any messages, by mail, cable,
telegraph, telex or otherwise, whether or not they are in cipher, unless any of
the foregoing are caused by Lender's gross negligence or willful misconduct; (E)
for errors in interpretation of technical terms; (F) for any loss or delay in
the transmission of any document required in order to make a drawing under any
such Letter of Credit or of the proceeds thereof, unless caused by Lender's
gross negligence or willful misconduct; (G) for the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of any drawing under
such Letter of Credit; and (H) for any consequences arising from causes beyond
the control of Lender, including, without limitation, any Government Acts. None
of the above shall affect, impair, or prevent the vesting of any of Lender's
rights or powers hereunder.

          (iii)  In furtherance and extension and not in limitation of the
specific provisions hereinabove set forth, any action taken or omitted by Lender
in connection with the Letters of Credit issued by it or the related
certificates, if taken or omitted in good faith, shall not create any liability
on the part of Lender to Borrowers.

fiscal calendar quarters, beginning on the first Business Day of the first
fiscal calendar quarter after the Closing Date and on the day the Revolving

prepayment shall be accompanied by all accrued and unpaid interest thereon and a
prepayment premium equal to the amount, if any, by which the aggregate present

of Net Proceeds from any Offering, permanently prepay the Term Loans (in such
order as Borrowers may designate, but subject in any event to Section 2.11(b);
provided that if such prepayment may trigger a prepayment premium under Section
2.11(b), Borrowers may elect to have Lender retain such portion of the Net
Proceeds that would trigger a prepayment premium as cash collateral to be
released and applied to the applicable Term Loan in accordance with the
repayment schedule set forth in this Agreement) in an amount equal to such Net
Proceeds.  If the Term Loans have been prepaid in full then the Net Proceeds (or
balance thereof) shall be used to permanently reduce the Maximum Revolving
Credit Amount.  Any Overadvance resulting therefrom shall be paid in full on the
date of receipt of such Net Proceeds.  If a Default or Event of Default has
occurred and is continuing, the Net Proceeds may be applied to the Obligations
in such order as Lender may, in its discretion, determine but subject, in any
event to Section 2.11(b).

regulation, policy, guideline, directive or similar requirement (whether or not
having the force of law) imposes, modifies, or deems applicable any capital
adequacy, capital maintenance or similar requirement which affects the manner in
which Lender allocates capital resources to its commitments (including any
commitments hereunder), and as a result thereof, the rate of return on Lender's
capital with regard to the Loans is reduced to a level below that which Lender
could have achieved but for such circumstances, then in such case and upon
notice from Lender to Borrowers, from time to time, Borrowers shall pay Lender
such additional amount or amounts as shall compensate Lender for such reduction
in Lender's rate of return.  Such notice shall contain the statement of Lender
with regard to any such amount or amounts which shall, be prima facie evidence
of such amount owing from Borrowers.  In determining such amount, Lender may use
any reasonable method of averaging and attribution that it deems applicable.

     2.13  Use of Proceeds  :  Proceeds of the Loans shall be used to (a) repay
           ---------------

are indefeasibly paid and satisfied in full and the Revolving Credit has been
terminated that:

     6.1  Payment of Taxes and Claims  :  Each Borrower shall pay, before they
          ---------------------------                                         
become delinquent,

          (a) all taxes, assessments and governmental charges or levies imposed
upon it or upon such Borrowers' Property, and

          (b) all claims or demands of materialmen, mechanics, carriers,
warehousemen, landlords and other Persons entitled to the benefit of statutory
or common law Liens,

which, if unpaid, would result in the imposition of a Lien upon its Property;
provided, however, that such Borrower shall not be required to pay any such tax,
assessment, charge, levy, claim or demand if the amount, applicability or
validity thereof shall at the time be contested in good faith and by appropriate
proceedings by such Borrower, and if such Borrower shall have set aside on its
books adequate reserves in respect thereof, if so required in accordance with
GAAP, consistently applied; which deferment of payment is permissible so long as
no Lien has been entered and such Borrower's title to, and its right to use, its
Property are not materially adversely affected thereby.

          -------------------------------------------------

(including, without limitation, extended coverage, workmen's compensation,
boiler and machinery, with inflation coverage by endorsement) in such amounts
(but not less than 80% of the insurable value of the assets), with such
deductibles and with such insurers as are customarily used by companies
operating in the same or similar business located in the same or similar area as
Borrowers.  At or prior to Closing, Borrowers shall furnish Lender with
duplicate original policies of insurance or such other evidence of insurance as
Lender may require.  In the event Borrowers fail to procure or cause to be
procured any such insurance or to timely pay or cause to be paid the premium(s)
on any such insurance, Lender may do so for Borrowers, but Borrowers shall
continue to be liable for the same.  The policies of all such casualty insurance
shall contain standard Lender's Loss Payable Clauses issued in favor of Lender

may appear.  Such policies shall expressly provide that the requisite insurance
cannot be altered or canceled without thirty (30) days prior written notice to
Lender and shall insure Lender notwithstanding the act or neglect of any
Borrower.  Each Borrower hereby appoints Lender as such Borrower's attorney-in-

amount or amounts collected by Lender pursuant to the provisions of this
paragraph may be applied by Lender, in its sole discretion, to any Obligations
or to repair, reconstruct or replace the loss of or damage to Collateral as
Lender in its judgment may from time to time determine.  Borrowers further

its insurance company of any such policy.

liability, products liability and business interruption insurance in such
amounts as is customary for companies operating in the same or similar
businesses located in the same or similar area.

environmental-related laws, statutes, ordinances, rules, regulations and

governmental authorizations necessary to the ownership of its Property or to the
conduct of its businesses, which violation or failure to obtain may materially
adversely affect the business, Property, financial condition or prospects of
such Borrower.  Borrowers shall timely satisfy all assessments, fines, costs and

of any Borrower.

Agreement.

employer pension plan in which it participates and will promptly advise Lender
(x) upon its receipt of notice of the assertion against such Borrower of a claim
for withdrawal liability, (y) upon the occurrence of any event which, to the
best of each Borrower's knowledge, would trigger the assertion of a claim for
withdrawal liability against Borrower, and (z) upon the occurrence of any event
which, to the best of each Borrower's knowledge, would place any Borrower in a
Controlled Group as a result of which any member (including such Borrower)

ERISA, so that grounds exist to permit the appointment of a trustee under ERISA

proceedings to appoint a trustee to administer such plan(s), or to permit the
entry of a Lien to secure any deficiency or claim; or

          (p) Investigations - any evidence received by Lender that reasonably

necessary to the next 1/16 of 1%) determined pursuant to the following formula:

          Adjusted LIBOR Rate    =            LIBOR Rate
                                     ------------------------------
                                        (1 - Reverse Percentage)

of interest per annum (rounded upwards, if necessary to the next 1/16 of 1%) at
which Lender is offered deposits of United States Dollars in the London
interbank market on or about eleven o'clock (11:00) a.m. London Time two (2)
Business Days prior to the commencement of such LIBOR Interest Period on amounts
substantially equal to the LIBOR Based Rate Loan as to which Borrowers may elect
the Adjusted LIBOR Rate to be applicable with a maturity of comparable duration
to the LIBOR Interest Period selected by Borrowers for such LIBOR Based Rate
Loan.

Loan C and Term Loan D.

        c.  Upon the Effective Date, Section 2.7 of the Loan Agreement is
hereby amended and restated in its entirety and shall read as follows:

          2.7  Revolving Credit Interest
               -------------------------

               (a) Revolving Credit Base Rate - Subject to Section 2.7(b), the
                   ------------------------- 
unpaid principal balance of cash Advances under the Revolving Credit shall bear
interest, subject to the terms hereof, at the per annum rate equal to the
Revolving Credit Base Rate.  Interest on Base Rate Loans under the Revolving
Credit shall be payable monthly, in arrears, on the first day of each calendar
month, beginning on the first day of the first full calendar month after the
Closing Date and on the Revolving Credit Maturity Date.

               (b)  LIBOR Rate Option:
                    ----------------- 

                    (i) So long as no Default or Event of Default has occurred
and is continuing, Borrowers may choose to have all or a portion of the
Revolving Credit accrue interest at the Revolving Credit LIBOR Rate by giving
Lender at least two (2) Business Days' prior written notice. Such notice shall
specify the LIBOR Interest Period and the portion of outstanding Advances under
the Revolving Credit (but in no event less than $500,000), to bear interest at
the Revolving Credit LIBOR Rate.

                    (ii) Borrowers shall select a LIBOR Interest Period during
which the Revolving Credit LIBOR Rate is applicable; provided, however, that if
the LIBOR Interest Period would otherwise end on a day which shall not be a
London Business 

                                       4
<PAGE>
 
Day, such LIBOR Interest Period shall be extended to the next preceding or
succeeding London Business Day as is Lender's custom in the market in which such
LIBOR Based Rate Loan relates. Interest shall accrue from and including the
first day of each LIBOR Interest Period to, but excluding the day on which any
LIBOR Interest Period expires. For any LIBOR Interest Period which begins on the
last London Business Day of a calendar month (or on a day for which there is no
numerically corresponding day in the calendar month at the end of such LIBOR
Interest Period), the LIBOR Interest Period shall end on the last London
Business Day of a calendar month. All accrued and unpaid interest on a LIBOR
Based Rate Loan must be repaid in full on the last day of the applicable LIBOR
Interest Period. Interest shall also be due and payable for a six month LIBOR
Interest Period on the day that would have been the last day of a three month
LIBOR Interest Period. No LIBOR Interest Period with respect to the Revolving
Credit may end after the Revolving Credit Maturity Date. Subject to all of the
terms and conditions applicable to a request for a LIBOR Based Rate Loan,
Borrowers may convert an existing LIBOR Based Rate Loan as of the last day of
the LIBOR Interest Period to a new LIBOR Based Rate Loan provided all interest
accrued under the expiring LIBOR Interest Period has been paid. If Borrowers
fail to notify Lender of the LIBOR Interest Period for such a subsequent LIBOR
Based Rate Loan at least two (2) Business Days prior to the last day of the then
current LIBOR Interest Period of such an outstanding LIBOR Based Rate Loan, then
such outstanding LIBOR Based Rate Loan shall become a Base Rate Loan at the end
of the current LIBOR Interest Period and shall accrue interest at the Revolving
Credit Base Rate in accordance with Section 2.7(a) above.

                    (iii) The Adjusted LIBOR Rate may be automatically adjusted
by Lender on a prospective basis to take into account the additional or
increased cost of maintaining any necessary reserves for Eurodollar deposits or
increased costs due to changes in applicable law or regulation or the
interpretation thereof occurring subsequent to the commencement of the then
applicable LIBOR Interest Period, including but not limited to changes in tax
laws (except changes of general applicability in corporate income tax laws) and
changes in the reserve requirements imposed by the Board of Governors of the
Federal Reserve System (or any successor), excluding the Reserve Percentage
which has resulted in a payment pursuant to Section 2.17 below, that increase
the cost to Lender of funding the LIBOR Based Rate Loan. Lender shall promptly
give Borrowers notice of such a determination and adjustment, which
determination shall be, except for error, and absent written notice from
Borrowers to Lender within ten (10) days from submission, final, conclusive and
binding for all purposes; provided that Borrowers shall not be liable for any
amount payable with respect to any period more than 90 days before the date of
such notice.

                    (iv) If Borrowers have requested the rate based on the
Adjusted LIBOR Rate in accordance with Section 2.7(b), and Lender shall have
reasonably determined that Eurodollar deposits equal to the amount of the
principal of the requested LIBOR Based Rate Loan and for the LIBOR Interest
Period specified are unavailable, or

                                       5
<PAGE>
 
that the rate based on the Adjusted LIBOR Rate will not adequately and fairly
reflect the cost of the Adjusted LIBOR Rate applicable to the specified LIBOR
Interest Period, of making or maintaining the principal amount of the requested
LIBOR Based Rate Loan specified by Borrowers during the LIBOR Interest Period
specified, or that by reason of circumstances affecting Eurodollar markets,
adequate and reasonable means do not exist for ascertaining the rate based on
the Adjusted LIBOR Rate applicable to the specified LIBOR Interest Period,
Lender shall promptly give notice of such determination to Borrowers that the
rate based on the Adjusted LIBOR Rate is not available. A determination by
Lender hereunder shall be prima facie evidence of the correctness of the fact
and amount of such additional costs or unavailability. Upon such a
determination, (A) the obligation to establish, convert to, or maintain a LIBOR
Based Rate Loan at the rate based on the Adjusted LIBOR Rate shall be suspended
until Lender shall have notified Borrowers that such conditions shall have
ceased to exist (which notification shall be given promptly by Lender after such
cessation), and (B) the applicable Revolving Credit portion subject to the
requested conversion shall continue to accrue interest at the Revolving Credit
Base Rate in accordance with Section 2.7(a) above.

                    (v) If, as a result of any changes in applicable law or
regulation or the interpretation thereof, it becomes unlawful for Lender to
maintain Eurodollar liabilities sufficient to fund any LIBOR Based Rate Loan
subject to the rate based on the Adjusted LIBOR Rate, then Lender shall
immediately notify Borrowers thereof and Lender's obligations hereunder to
convert to, or maintain a LIBOR Based Rate Loan at the rate based on the
Adjusted LIBOR Rate shall be suspended until such time as Lender may again cause
the rate based on the Adjusted LIBOR Rate to be applicable. Immediately upon
such occurrence, the portion of the Revolving Credit that was subject to the
Revolving Credit LIBOR Rate shall thereupon accrue interest at the Revolving
Credit Base Rate in accordance with Section 2.7(a) above. Promptly after coming
aware that it is no longer unlawful for Lender maintain such Eurodollar
liabilities, Lender shall notify Borrowers thereof and such suspension shall
cease to exist.

        d.  Upon the Effective Date, Section 2.9 of the Loan Agreement is
hereby amended and restated in its entirety and shall read as follows:

            2.9  Additional Interest Provisions.
                 ------------------------------ 

                    (a) Calculation of Interest. Interest on the Loans,
                        -----------------------
regardless of the rate option, shall be charged on the basis of a year of three
hundred sixty (360) days but charged for the actual number of days elapsed.
Changes in the interest rate applicable to Base Rate Loans shall become
effective on the same day as Lender announces a change in its Prime Rate or, if
applicable, the date the Fed Funds Rate change.

                    (b) Limitation on LIBOR Based Rate Loans. All Loans not
                        ------------------------------------
specifically designated by Borrowers, pursuant to the terms hereof or not
requested in conformity with the terms hereof, shall be Base Rate Loans. No
LIBOR Based Rate Loans 

                                       6
<PAGE>
 
shall be requested by Borrowers or made available by Lender if a Default or an
Event of Default has occurred and is continuing hereunder. There may not be more
than five (5) LIBOR Based Rate Loans outstanding at any one time.

                    (c) Default Rate. Upon the occurrence and during the
                        ------------
continuance of an Event of Default hereunder, the per annum effective rate of
interest on all outstanding principal under the Loans, regardless of the rate
option, and all fees for Letters of Credit, shall, be increased by three hundred
(300) basis points.

                    (d) Termination of LIBOR Based Rate Loans. Without impairing
                        -------------------------------------
Lender's rights under Section 2.9(c), all LIBOR Based Rate Loans shall
automatically convert to Base Rate Loans upon the occurrence of an Event of
Default.

                    (e) Continuation of Interest Charges. All contractual rates
                        --------------------------------
of interest chargeable on outstanding principal under the Loans, regardless of
the rate option, shall continue to accrue and be paid even after Default, Event
of Default, maturity, acceleration, judgment, bankruptcy, insolvency proceedings
of any kind or the happening of any event or occurrence similar or dissimilar.

                    (f) Applicable Interest Limitations: In no contingency or
                        -------------------------------   
event whatsoever shall the aggregate of all amounts deemed interest hereunder
and charged or collected pursuant to the terms of this Agreement exceed the
highest rate permissible under any law which a court of competent jurisdiction
shall, in a final determination, deem applicable hereto. In the event that such
court determines Lender has charged or received interest hereunder in excess of
the highest applicable rate, Lender shall apply, in its sole discretion, and set
off such excess interest received by Lender against other Obligations due or to
become due and such rate shall automatically be reduced to the maximum rate
permitted by such law.

          e.  Effective on the Effective Date, the following Section 2.16 is
hereby added to the Loan Agreement:

               2.16  Term Loan D:
                     ----------- 

                    (a) Description. Lender hereby advances to Borrowers,
                         -----------
subject to the terms of this Agreement, the original principal sum of Seven
Million Five Hundred Thousand Dollars ($7,500,000.00) ("Term Loan D").

                    (b) Term Loan D Note. As a condition to the effectiveness of
                        ----------------
this Amendment, Borrowers shall execute and deliver their promissory note (the
"Term Loan D Note") to Lender for the total principal amount of Term Loan D. The
Term Loan D Note shall evidence each Borrowers' absolute and unconditional
obligation to repay Lender for Term Loan D with interest as herein and therein
provided. The obligations of 

                                       7
<PAGE>
 
Borrowers under the Term Loan D Note shall at all times be joint and several.
The Term Loan D Note shall be in form and substance satisfactory to Lender.

                    (c) Amortization. The principal amount of Term Loan D shall
                        ------------
be payable in fifty three (53) equal consecutive monthly installments of
principal in the amount of $138,000 plus interest thereon at the rate set forth
herein. The first such installment shall be due and payable on July 1, 1998 and
the remaining such installments shall be due on the first Business Day of each
calendar month thereafter. A final fifty fourth (54th) installment of the
remaining outstanding principal, together with all accrued and unpaid interest
on Term Loan D, shall be due and payable on December 1, 2002, unless having been
sooner accelerated pursuant to the terms hereof.

                    (d)  Term Loan D Interest.
                         -------------------- 

                         (i) Term Loan Base Rate. Subject to Section
                             -------------------
2.16(d)(ii), the unpaid principal balance of Term Loan D shall bear interest,
subject to the terms hereof, at the per annum rate equal to the Term Loan D Base
Rate. Interest on Base Rate Loans under Term Loan D shall be payable monthly, in
arrears, on the first Business Day of each calendar month, beginning on the
first Business Day of the first full calendar month after the date hereof and on
December 1, 2002.

                         (ii)  LIBOR Rate Option.
                               ----------------- 

                               (A) So long as no Default or Event of Default has
occurred and is continuing, Borrowers may choose to have all or a portion of
Term Loan D accrue interest at the Term Loan D LIBOR Rate by giving Lender at
least two (2) Business Days' prior written notice. Such notice shall specify the
LIBOR Interest Period and the portion of Term Loan D (but in no event less than
$500,000), to bear interest at the Term Loan D LIBOR Rate. At no time, however,
may any LIBOR Rate Loan applicable to Term Loan D include any principal
installments on Term Loan D required to be made during the chosen LIBOR Interest
Period.

                               (B) Borrowers shall elect a LIBOR Interest Period
during which the Term Loan D LIBOR Rate is applicable; provided, however, that
if the LIBOR Interest Period would otherwise end on a day which shall not be a
London Business Day, such LIBOR Interest Period shall be extended to the next
preceding or succeeding London Business Day as is Lender's custom in the market
in which such LIBOR Based Rate Loan relates. Interest shall accrue from and
including the first day of each LIBOR Interest Period to, but excluding the day
on which any LIBOR Interest Period expires. For any LIBOR Interest Period which
begins on the last London Business Day of a calendar month (or on a day for
which there is no numerically corresponding day in the calendar month at the end
of such LIBOR Interest Period), the LIBOR Interest Period shall end on the last
London Business Day of a calendar month. All accrued and unpaid interest

                                       8
<PAGE>
 
on a LIBOR Based Rate Loan must be repaid in full on the last day the applicable
LIBOR Interest Period. Interest shall also be due and payable for a six month
LIBOR Interest Period on the day that would have been the last day of a three
month LIBOR Interest Period. No LIBOR Interest Period may end after December 31,
2002. Subject to all of the terms and conditions applicable to a request for a
LIBOR Based Rate Loan, Borrowers may convert an existing LIBOR Based Rate Loan
as of the last day of the LIBOR Interest Period to a new LIBOR Based Rate Loan
provided all interest accrued under the expiring LIBOR Interest Period has been
paid. If Borrowers fail to notify Lender of the LIBOR Interest Period for a
subsequent LIBOR Based Rate Loan at least two (2) Business Days prior to the
last day of the then current LIBOR Interest Period of an outstanding LIBOR Based
Rate Loan, then such outstanding LIBOR Based Rate Loan shall become a Base Rate
Loan at the end of the current LIBOR Interest Period for such outstanding LIBOR
Based Rate Loan and shall accrue interest at the Term Loan D Base Rate in
accordance with Section 2.16(d)(i) above.

                               (C) The Adjusted LIBOR Rate may be automatically
adjusted by Lender on a prospective basis to take into account the additional or
increased cost of maintaining any necessary reserves for Eurodollar deposits or
increased costs due to changes in applicable law or regulation or the
interpretation thereof occurring subsequent to the commencement of the then
applicable LIBOR Interest Period, including but not limited to changes in tax
laws (except changes of general applicability in corporate or other income tax
laws) and changes in the reserve requirements imposed by the Board of Governors
of the Federal Reserve System (or any successor), excluding the Reserve
Percentage which has resulted in a payment pursuant to Section 2.17 below, that
increase the cost to Lender of funding the LIBOR Based Rate Loan. Lender shall
promptly give Borrowers notice of such a determination and adjustment, which
determination shall be, except for error, and absent written notice from
Borrowers to Lender within ten (10 ) days from submission, final, conclusive and
binding for all purposes; provided that Borrowers shall not be liable for any
amount payable with respect to any period more than 90 days before the date of
such notice.

                               (D) If Borrowers have requested the rate based on
the Adjusted LIBOR Rate in accordance with Section 2.16(d)(ii) and Lender shall
have reasonably determined that Eurodollar deposits equal to the amount of the
principal of the requested LIBOR Based Rate Loan and for the LIBOR Interest
Period specified are unavailable, or that the rate based on the Adjusted LIBOR
Rate will not adequately and fairly reflect the cost of the Adjusted LIBOR Rate
applicable to the specified LIBOR Interest Period, of making or maintaining the
principal amount of the requested LIBOR Based Rate Loan specified by Borrowers
during the LIBOR Interest Period specified, or that by reason of circumstances
affecting Eurodollar markets, adequate and reasonable means do not exist for
ascertaining the rate based on the Adjusted LIBOR Rate applicable to the
specified LIBOR Interest Period, Lender shall promptly give notice of such
determination to Borrowers that the rate based on the Adjusted LIBOR Rate is not
available. A determination 

                                       9
<PAGE>
 
by Lender hereunder shall be prima facie evidence of the correctness of the fact
and amount of such additional costs or unavailability. Upon such a
determination, (A) the obligation to establish, convert to, or maintain a LIBOR
Based Rate Loan at the rate based on the Adjusted LIBOR Rate shall be suspended
until Lender shall have notified Borrowers that such conditions shall have
ceased to exist (which notification shall be given promptly by Lender after such
cessation), and (B) the portion of Term Loan D subject to the requested
conversion shall continue to accrue interest at the Term Loan Base D Rate in
accordance with Section 2.16(d)(i) above.

                              (E) If, as a result of any changes in applicable
law or regulation or the interpretation thereof, it becomes unlawful for Lender
to maintain Eurodollar liabilities sufficient to fund any LIBOR Based Rate Loan
subject to the rate based on the Adjusted LIBOR Rate, then Lender shall
immediately Borrowers thereof and Lender's obligations hereunder to convert to,
or maintain a LIBOR Based Rate Loan at the rate based on the Adjusted LIBOR Rate
shall be suspended until such time as Lender may again cause the rate based on
the Adjusted LIBOR Rate to be applicable. Immediately upon such occurrence, the
portion of Term Loan D that was subject to the Term Loan D LIBOR Rate, shall
thereupon accrue interest at the Term Loan D Base Rate in accordance with
Section 2.16(d)(i) above. Promptly after becoming aware that it is no longer
unlawful for Lender to maintain such Eurodollar liabilities, Lender shall notify
Borrowers thereof and such suspension shall cease to exist.

          f.  Effective on the Effective Date, the following Section 2.17 is
hereby added to the Loan Agreement:

            2.17 Indemnity. Borrowers shall indemnify, defend and hold harmless
                 ---------                                                      
Lender against any and all loss, liability, cost or expense which Lender may
sustain or incur (including, without limitation, loss of any merger with respect
to a LIBOR Based Rate Loan) as a consequence of (a) any failure of Borrowers to
convert or extend any LIBOR Based Rate Loan after proper notice thereof has been
given to Lender in accordance with the terms of this Agreement; or (b) any
payment, prepayment or conversion of a LIBOR Based Rate Loan by Borrowers made
for any reason (other than pursuant to Section 2.9(b)(v) and 2.16(d)(ii)(E)) on
a date other than the last day of the applicable LIBOR Interest Period.
Borrowers shall pay the full amount thereof to Lender on demand by Lender.
