                               PROSPECTUS SUMMARY

     THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND THE CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO
APPEARING ELSEWHERE IN THIS PROSPECTUS. EXCEPT AS OTHERWISE NOTED OR UNLESS THE
CONTEXT OTHERWISE REQUIRES, THE INFORMATION CONTAINED IN THIS PROSPECTUS ASSUMES
NO EXERCISE OF THE OVER-ALLOTMENT OPTION GRANTED BY THE COMPANY TO THE
UNDERWRITERS.

                                  THE COMPANY

     HCIA is a leading health care information content company that develops and
markets integrated clinical information systems and products. The Company's
systems and products range from standardized data bases to highly focused
Decision Support Systems that assist its customers in evaluating the efficacy
and economics of health care delivery. HCIA currently sells its Decision Support
Systems to more than 325 customers, including hospitals, integrated delivery
systems, self-insured employers, pharmaceutical companies and managed care
organizations. The Company's Syndicated Products are sold to more than 7,000
customers.

     By utilizing its core collection of proprietary data standardization
methodologies, value-added clinical measurement tools and data bases, including
the International Classification of Clinical Services System(TM) (the "ICCS
System(TM)"), the Company creates clinical information systems and products from
its many large and disparate data streams. The ICCS System(TM) allows for the
standardization and comparison of detailed clinical data across a broad range of
data sources. The Company's proprietary disease management methodologies link
the costs, quality, utilization and outcomes of medical services delivered to
patients in various clinical settings. These methodologies and technical
resources permit the Company to provide a level of clinical information that is
substantially more detailed and useful in modifying clinical practice patterns
than information derived from traditional health care data sources.

   
     As a result of its unique ability to integrate health care data collected
from numerous sources and across varied treatment settings, the Company believes
that it is well positioned to offer the information systems and products
necessary to continue to increase average revenue per customer through the sale
of more sophisticated and comprehensive Decision Support Systems. The Company
continually seeks to enhance its systems and products through internal product
development efforts and acquisitions of other companies, product lines and data
resources, as well as through the creation of strategic relationships with key
health care industry participants. Since 1991 the Company has acquired, as part
of its overall growth strategy, a total of 15 health care information companies,
product lines and data resources. Most recently, on August 9, 1996 the Company
acquired LBA Health Care Management, Inc. ("LBA"), a provider of sophisticated
health care information products. See "Business -- Recent Developments."
    

     The Company utilizes a highly specialized direct field sales force to
market Decision Support Systems. The Company's marketing and pricing strategies
are focused on the generation of recurring revenue from Decision Support Systems
through multi-year agreements (typically two to three years) and through the
renewal of its Syndicated Products, which are updated annually. During 1995,
approximately 69% of the Company's revenue was recurring in nature. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview."

"HCIA" and the "Company" refer to HCIA Inc. and its predecessors and
subsidiaries. The Company's executive offices are located at 300 East Lombard
Street, Baltimore, Maryland 21202, and its telephone number is (410) 895-7470.

     LBA HEALTH CARE. On August 9, 1996, the Company acquired LBA for

consumption and (iii) optimizing labor utilization. LBA's principal products
include its VALUE ENHANCEMENT systems and Centers of Excellence programs which
utilize comparative data base analyses and a clinical implementation management
team to assist customers in reducing clinical resource consumption and improving
outcomes in specific practice areas, such as orthopaedics and cardiology. LBA's
proprietary data bases contain detailed data from approximately 250 providers
and provider groups that are LBA customers.
    

     RESPONSE HEALTHCARE. In May 1996, the Company acquired Response Healthcare
Information Management, Inc. ("Response") for approximately $6.2 million in
cash. The acquisition of Response provides the Company with expertise and
products in patient-centered data collection and represents a significant
enhancement of the Company's system and product offerings to the managed care
market.

(1) Effective as of January 1, 1994, the Company divested certain of its
    software product lines, which generated revenue of approximately $3.0
    million during 1993. During 1995 and 1996, the Company completed several
    acquisitions which were accounted for using the purchase method of
    accounting. In connection with certain of these acquisitions, the Company
    recorded one-time charges related to acquired in-process research and
    development costs. See "Pro Forma Financial Statements" and Note 1 of the
    Notes to Consolidated Financial Statements.

(2) Exclusive of a one-time charge incurred in 1995, operating income, net
    income and net income per share would have been $7,164,000, $4,843,000 and
    $0.60, respectively.

   
(3) As adjusted using the purchase method of accounting to give effect to the
    acquisitions of (i) Datis Corporation ("Datis"), (ii) the CHAMP unit

    interest in CHKS Limited ("CHKS"), (iv) Response and (v) LBA (together, the
    "Acquired Companies") as if such acquisitions had occurred immediately
    before the beginning of the period presented. Also adjusted to reflect the
    sale by the Company of 2,000,000 shares of Common Stock offered hereby at an
    assumed offering price of $60 per share, after deducting underwriting
    discounts and commissions and estimated offering expenses and the
    application of the estimated net proceeds therefrom as described under "Use
    of Proceeds." The pro forma information is not necessarily indicative of
    future results of operations of the Company or the results which would have
    occurred had the operations and management of the Company and the Acquired
    Companies been combined during the period presented. See "Pro Forma
    Financial Statements."
    

   
(4) Exclusive of a one-time charge incurred in 1996, operating income, net
    income and net income per share would have been $5,538,000, $3,631,000 and
    $0.38, respectively.
    

   
(5) As adjusted using the purchase method of accounting to give effect to the
    Response and LBA acquisitions as if they had occurred on December 31, 1995.

                                  RISK FACTORS

     IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING
FACTORS SHOULD BE CONSIDERED CAREFULLY BY PROSPECTIVE INVESTORS.

   
     ACQUISITIONS.  The Company has, in part, expanded its systems and products
through the acquisition of health care information companies, product lines and
data resources, including the Company's recent acquisitions of Response and LBA.
The Company intends to continue the acquisition of methodological, analytical
and technical resources that will further enhance and expand the Company's
systems and products. The Company currently has no agreements, commitments or
understandings with respect to any such acquisitions.
    

     Acquisitions involve numerous risks, including difficulties in the
assimilation of operations and products, the ability to manage geographically
remote units, the diversion of management's attention from other business
concerns, the risks of entering markets in which the Company has limited or no
direct expertise and the potential loss of key employees of the acquired
companies. In addition, acquisitions may involve the expenditure of significant
funds and the incurrence of significant charges associated with the amortization
of goodwill or other intangible assets, write-offs of acquired in-process
research and development costs and/or future write-downs of the recorded values
of assets acquired. There can be no assurance that any acquisition will result
in long-term benefits to the Company or that management will be able to manage
effectively the resulting business. See "Business -- Business Strategy."

     In connection with the LBA acquisition, the Company expects to incur a
one-time charge in the third quarter of 1996 of approximately $41.2 million
related to acquired in-process research and development costs. The Company also
will record significant goodwill and other intangible assets associated with the
LBA acquisition, which the Company intends to amortize over periods of six to
twenty years. In addition, the LBA acquisition will result in a significant
expansion of the Company's system and product offerings, and the integration of
LBA with the Company will require significant management time and resources.
There can be no assurance that the Company will be able to integrate LBA systems
with the Company's existing systems and products or achieve the operating
synergies necessary to make the acquisition successful.

     MANAGEMENT OF GROWTH.  The Company is currently experiencing a period of
rapid growth and expansion which could place a significant strain on the
Company's personnel and resources. The Company's growth has resulted in an
increase in the level of responsibility for both existing and new management
personnel. Many of the Company's management personnel have had limited or no
experience in managing companies as large as the Company. The Company has sought
to manage its current and anticipated growth through the recruitment of
additional management and technical personnel and the implementation of internal
systems and controls. However, the failure to manage growth effectively could
adversely affect the Company's operating results. See "Business -- Business
Strategy" and "Management."

     DEPENDENCE ON KEY PERSONNEL.  The Company depends to a significant extent
on key management, technical and marketing personnel. The Company's growth and
future success will depend in large part on its ability to attract, motivate and
retain highly qualified personnel, including management personnel of acquired
companies. Except for an agreement with George D. Pillari, its Chairman of the
Board, President and Chief Executive Officer, the Company does not have
employment agreements with any of its officers. The loss of key personnel or the
inability to hire or retain qualified personnel could have a material adverse
effect on the Company. See "Management."

   
     SHORT HISTORY OF PROFITABILITY; VARIATIONS IN QUARTERLY RESULTS.  After
achieving profitability during 1993 and 1994, the Company recorded a net loss
for 1995 as a result of the one-time charge incurred during the period related
to acquired in-process research and development costs in connection with the
CHAMP acquisition. The Company has recorded net income of approximately $964,000
for the six months ended June 30, 1996. However, there can be no assurance that
revenue growth or profitable operations can be sustained in the future. The
Company has experienced and expects to continue to experience variations in
quarterly results. Recent quarterly variations are primarily due to the effect
of one-time charges related to acquired in-process research and development
costs. Quarterly results are also influenced by the timing of release of certain
systems and products as a result of the annual release of certain external data
sources. The Company's operating results for any particular quarterly
    

                                       6

<PAGE>
or annual period may not be indicative of results for future periods. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Quarterly Results of Operations."

     DEPENDENCE ON INTELLECTUAL PROPERTY RIGHTS.  The Company has made
significant investments in the development and maintenance of its core
collection of proprietary data standardization methodologies, value-added
clinical measurement tools and technical resources that are used to transform
its many large and disparate data streams into clinically relevant information
products. See "Business -- Systems and Products." The Company relies largely on
its license agreements with customers and its own security systems,
confidentiality procedures and employee nondisclosure agreements to maintain the
trade secrecy of its proprietary information. There can be no assurance that the
legal protections and precautions taken by the Company will be adequate to
prevent misappropriation of the Company's proprietary information. In addition,
these protections do not prevent independent third-party development of
functionally equivalent or superior systems, products or methodologies. See
"Business -- Intellectual Property."

     COMPETITION.  The health care information market is intensely competitive
and rapidly changing. The Company competes for the sale of systems and products
and the resulting access to data with different companies in each of its target
markets. Competitors vary in size and in the scope and breadth of the products
and services offered. Many of the Company's competitors have significantly
greater financial, technical, product development and marketing resources than
the Company. There can be no assurance that future competition, or any
significant loss of access to data resulting therefrom, will not have a material
adverse effect on the Company. See "Business -- Competition."

     MAJOR CUSTOMERS.  In 1994, one customer, Amgen Inc., accounted for
approximately 12% of the Company's revenue. In 1995, no customer accounted for
10% or more of the Company's revenue. During 1994 and 1995, the Company's ten
largest customers accounted for approximately 29% and 36%, respectively, of the
Company's revenue. Many of the Company's contractual arrangements with its
customers are subject to annual renewal. The loss of one or more of the
Company's largest customers could have a material adverse effect on the Company.
See "Business -- Customers."

     INTEGRITY AND RELIABILITY OF DATA. The Company's success depends
significantly on the integrity of its data. Although the Company tests data for
completeness and consistency, it does not conduct independent audits of the
information provided by its customers. Moreover, while the Company believes that
the benchmarking and other clinical, cost and performance information contained
in its data base is representative of the operational aspects of various types
of health care industry participants, there can be no assurance that such
information is appropriate for comparative analysis in all cases or that the
data bases accurately reflect general or specific trends in the health care
market. If the information contained in the data were found, or were perceived,
to be inaccurate, or if such information were generally perceived to be
unreliable, the Company's business and operating results could be materially and
adversely affected.

     POTENTIAL COST OF PERFORMANCE GUARANTEES. As part of its VALUE ENHANCEMENT
systems, LBA has guaranteed that each customer will achieve a cost savings
identified as at least equal to the fees the customer pays for the system. To
the extent such cost savings are not achieved, LBA may be subject to claims
related to such guarantees. Although LBA has never incurred a claim under its
guarantee, there can be no assurance that this will continue to be the case.
Liabilities related to such claims could have a material adverse effect on the
Company's business and operating results could be materially and adversely
affected.

     VOLATILITY OF STOCK PRICE.  The stock market historically has experienced
volatility which has affected the market price of securities of many companies
and which has sometimes been unrelated to the operating performance of such
companies. The trading price of the Common Stock may be subject to significant
fluctuations in response to variations in quarterly results of operations,
announcements of acquisitions, new systems or products by the Company or its
competitors, governmental regulatory action, other developments or disputes with
respect to proprietary rights, general trends in the industry and overall market
conditions, and other factors.

     CHANGES IN THE HEALTH CARE INDUSTRY.  The health care industry is subject
to changing political, economic and regulatory influences that may affect the
procurement practices and operation of health care industry participants. During
the past several years, the U.S. health care industry has been subject to an
increase in governmental

                                       7

<PAGE>
regulation of, among other things, reimbursement rates and certain capital
expenditures. Various programs have been proposed to reform the U.S. health care
system. Many of these programs contain proposals to increase governmental
involvement in health care, lower reimbursement rates and otherwise change the
operating environment for the Company's customers. Health care industry
participants may react to these proposals and the uncertainty surrounding such
proposals by curtailing or deferring investments, including those for the
Company's systems and products. The Company cannot predict what impact, if any,
such factors might have on its business, financial condition and results of
operations. In addition, many health care providers are consolidating to create
larger health care delivery enterprises with greater regional market power. As a
result, the remaining enterprises could have greater bargaining power, which may
lead to price erosion of the Company's systems and products. See
"Business -- Industry Background."

     GOVERNMENT REGULATION. The U.S. Food and Drug Administration (the "FDA")
has promulgated a draft policy addressing the regulation of certain computer
products as medical devices under the Federal Food, Drug, and Cosmetic Act. The
FDA could determine in the future that certain applications of the Company's
systems and products are clinical decision tools subject to FDA regulation as
medical devices. In addition, the Company could become subject to future
regulation of the manufacture and marketing of medical devices and health care
software systems, or to legislation or regulation regarding the use of patient
records or of access to health care data. Compliance with such legislation and
regulation could be burdensome, time consuming and expensive. The Company cannot
predict the effect of possible future legislation and regulation. See
"Business -- Government Regulation."

     On August 8, 1996, there were 37 holders of record of the Company's Common
Stock. The number of record holders is not representative of the number of
beneficial holders since many shares are held by depositories, brokers or other
nominees. On August 8, 1996, the last reported sale price of the Company's
Common Stock on NASDAQ was $60 per share.
    

                                DIVIDEND POLICY

     The Company has never paid any cash dividends on the Common Stock and does
not anticipate paying any cash dividends on the Common Stock in the foreseeable
future. The Company currently intends to retain any future earnings to fund the
development and growth of its business.

                                USE OF PROCEEDS

   
     The net proceeds to the Company from the sale of the Common Stock offered
by it hereby at an assumed price of $60 per share (the last reported sale price
of the Company's Common Stock on August 8, 1996) are estimated to be $114.1
million ($133.2 million if the Underwriters' over-allotment option is exercised
in full), after deducting the estimated underwriting discounts and offering
expenses payable by the Company. The Company will not receive any proceeds from
the sale of Common Stock by the Selling Stockholders.
    

   
     The Company intends to use the net proceeds (i) to repay $86 million
borrowed under a credit facility with First Union National Bank of North
Carolina, as agent and as an issuing bank ("First Union"), in connection with
the acquisition of LBA and (ii) for general corporate purposes, including future
acquisitions and funding the increased working capital requirements of the
Company as a result of its growth. Any proceeds not utilized to repay
indebtedness or for the other above-described purposes will be invested in
short-term, interest-bearing securities.
    

   
     Borrowings under the credit facility bear interest at varying rates based
on an index tied to First Union's prime rate or LIBOR (currently 8.75%). Upon
application of the net proceeds to the Company of the Offering to repay the
borrowings outstanding under the credit facility, the Company will maintain a
$50 million revolving line of credit for general corporate purposes, including
future acquisitions and working capital requirements. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

     The following table sets forth the capitalization of the Company (i) as of
June 30, 1996, (ii) on a pro forma basis to give effect to the LBA acquisition
and (iii) as further adjusted to reflect the sale by the Company of the
2,000,000 shares of Common Stock offered hereby (at an assumed offering price of
$60 per share) and the application of the estimated net proceeds to be received
by the Company therefrom as described under "Use of Proceeds." This table should

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
   
     HCIA is a health care information content company that develops and markets
Decision Support Systems and Syndicated Products. In 1991, HCIA began a series
of acquisitions of health care information companies, product lines and data
resources. These acquisitions established the Company's ability to provide
systems and products which rely on the integration of detailed clinical and
financial data. Effective as of January 1, 1994, the Company divested certain of
its software product lines, which had generated revenue of approximately $3.0
million during 1993. During 1995, the Company completed several additional
acquisitions of health care information companies, including Datis and the CHAMP
unit of Mercer. In connection with the CHAMP acquisition, the Company recorded a
one-time charge related to acquired in-process research and development costs of
approximately $12.2 million. As a result of this charge, the Company recorded a
net loss for the year ended December 31, 1995. In May 1996, the Company acquired
Response for approximately $6.2 million in cash. In connection with the Response
acquisition, the Company recorded a one-time charge during the three months
ended June 30, 1996 of approximately $4.4 million related to acquired in-process
research and development costs. On August 9, 1996, the Company acquired LBA. In
connection with the LBA acquisition, the Company expects to incur a one-time
charge during the three months ended September 30, 1996 of approximately $41.2
million related to acquired in-process research and development costs. The
Company's results of operations include the results of the acquired or divested
entities or product lines since the date of acquisition or prior to the date of
divestiture, as applicable. See Note 1 of the Notes to Consolidated Financial
Statements.
    
 
     The Company has made a substantial investment in the acquisition and
development of its core collection of methodologies, clinical measurement tools
and technical resources. The Company's strategy is to leverage these resources
across substantially all of its systems and products, thereby giving it the
ability to increase revenue generated from these resources without a
commensurate increase in expenses. In addition to its internal product
development efforts, the Company seeks to continue the acquisition of other
health care information companies, product lines and data resources, and intends
to integrate and leverage these assets into product-line extensions across its
markets. The Company does not track profitability by product line since many of
the Company's resources are utilized throughout its systems and products.
 
   
     The Company's internal product development efforts are generally in
connection with customer contracts, and the related costs are included as a
component of operating expenses in the year incurred. The Company capitalizes
costs related to internal product development which is not in connection with a
specific customer contract from the point of technological feasibility to the
point of general availability. With respect to acquired companies, product lines
and data resources, the Company has historically completed the acquisitions
using available cash or a deferred payment plan, with recent acquisitions being
funded by the proceeds of the Company's public offerings. The cash portion of
the LBA acquisition was financed by a credit facility which will be repaid with
a portion of the proceeds to the Company from the Offering. The Company also
issued a total of 492,961 shares of Common Stock to the stockholders of the
parent company of LBA. See " -- Liquidity and Capital Resources."
    
 
   
     As a result of its acquisition of health care information companies,
product lines and data resources, the Company has acquired intangible assets,
the cost of which it amortizes over various useful lives. In addition, the
Company has capitalized internal development costs and acquired assets relating
to the development of methodologies, clinical measurement tools and technical
resources, including its data base, of $3.3 million, $3.4 million, $6.9 million
and $6.3 million during 1993, 1994, 1995 and the six months ended June 30, 1996,
respectively. Consequently, the Company has recorded amortization expense of
$3.9 million, $3.9 million, $5.2 million and $3.7 million during 1993, 1994,
1995 and the six months ended June 30, 1996, respectively. See Notes 2 and 4 of
the Notes to Consolidated Financial Statements. On a pro forma basis, assuming
the completion of the Response and LBA acquisitions at the beginning of the
respective periods, the Company would have recorded additional amortization
expense of $5.1 million and $2.6 million during 1995 and the six months ended
June 30, 1996, respectively.

     As a result of its unique ability to integrate health care data collected
from numerous sources and across varied treatment settings, the Company believes
that it is well positioned to offer the information systems and products
necessary to continue to increase average revenue per customer through the sale
of more sophisticated and comprehensive Decision Support Systems. With respect
to Syndicated Products and entry-level Decision Support Systems, pricing is
relatively fixed and is influenced by competitive systems and products. With
respect to high-end Decision Support Systems, pricing is often negotiated with
the customer and is based on a number of factors, including the value attributed
by the customer to the System.

     The Company's revenue is comprised of both recurring revenue from the
Company's installed customer base as well as from first time sales. The Company
seeks to generate recurring revenue from Decision Support Systems through
multi-year agreements (typically two to three years) and through renewals of its
Syndicated Products, which are updated annually. The Company defines its
recurring revenue percentage as revenue recognized during the period from a sale
of a system or product to a customer who purchased a similar system or product
in the prior period, divided by the Company's total revenue in the prior period.
In determining its recurring revenue percentage, the Company includes in its
revenue the revenue of entities acquired during the period as if such
acquisitions had occurred at the beginning of the prior period. The Company does
not classify revenue as recurring to the extent that it exceeds the revenue from
a similar system or product purchase in the prior period. The Company's
recurring revenue percentages for 1994 and 1995 were approximately 64% and 69%,
respectively.

SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO SIX MONTHS ENDED JUNE 30, 1995
    

   
     REVENUE. Revenue for the six months ended June 30, 1996 was $30.7 million,
an increase of $9.7 million or 46% over the six months ended June 30, 1995. The
increase was primarily the result of a 49% increase in revenue from the sale of
Decision Support Systems. Revenue from the sale of Decision Support Systems
represented 81% of the revenue for the six months ended June 30, 1996 and
Syndicated Products represented the remaining 19% of revenue.
    
 
                                       14
 
<PAGE>
   
     The increase in Decision Support Systems revenue was primarily the result
of the Company's continued success in expanding its customer relationships in
the provider and supplier markets, and as a result of the acquisitions of Datis
and CHAMP.
    
 
   
     SALARIES, WAGES AND BENEFITS. Salaries, wages and benefits decreased to 44%
of revenue for the six months ended June 30, 1996 from 48% for the six months
ended June 30, 1995. This decrease was a result of the continued leveraging of
the Company's historical investments in technology and basic infrastructure as
revenue increased.
    
 
   
     OTHER OPERATING EXPENSES. Other operating expenses, which include
occupancy, travel, and marketing expenses, decreased to 22% of revenue for the
six months ended June 30, 1996 from 26% for the six months ended June 30, 1995.
This decrease was a result of certain of these expenses growing at a slower rate
than revenue.
    
 
   
     DEPRECIATION AND AMORTIZATION. Depreciation and amortization increased to
16% of revenue for the six months ended June 30, 1996 from 14% for the six
months ended June 30, 1995. This increase was a result of the additional
amortization associated with the acquisitions of Datis and CHAMP as well as
depreciation of other acquired assets.
    
 
   
     WRITE-OFF OF ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT COSTS. In
connection with the acquisition of Response, the Company acquired Response's
ongoing research and development activities. The Company recorded a one-time
charge of $4.4 million during the six months ended June 30, 1996 related to
acquired in-process research and development costs.
    
 
   
     INTEREST INCOME AND EXPENSE. Net interest income was $424,000 for the six
months ended June 30, 1996 compared with net interest income of $378,000 for the
six months ended June 30, 1995. This increase was the result of a higher
invested balance in 1996.
    
 
   
     INCOME TAXES. The Company's effective tax rate was 39.4% for the six months
ended June 30, 1996 compared with 43.6% for the six months ended June 30, 1995.
The decrease was the result of a portion of the Company's investments being
placed in tax-exempt securities, as well as the tax benefit associated with the
exercise of certain non-qualified stock options. This decrease was partially
offset by an increase in non-deductible goodwill and the non-deductible
write-off of the in-process research and development costs resulting from the
Response acquisition.
    
 
1995 COMPARED TO 1994
 
     REVENUE.  Revenue for 1995 was $48.0 million, an increase of $17.3 million
or 56% over 1994. The increase was primarily the result of a 77% increase in
revenue from the sale of Decision Support Systems. Revenue from the sale of
Decision Support Systems represented 80% of revenue for 1995 and Syndicated
Products represented the remaining 20% of revenue.
 
     The Decision Support Systems revenue increase was primarily the result of
increased sales of Decision Support Systems to providers, particularly as a
result of the acquisition of Datis during the year, and to a lesser extent, due
to increased sales through CHKS, the Company's English subsidiary. Sales of the
Company's Systems to the buyer and supplier markets also increased. In
particular, the Company met several performance milestones pursuant to its
contract with CIGNA Healthcare during the year.
 
     SALARIES, WAGES AND BENEFITS.  Salaries, wages and benefits decreased to
46% of revenue for 1995 from 50% for 1994. This decrease was a result of the
leveraging of the Company's historical investments in technology and basic
infrastructure as revenue increased.
 
     OTHER OPERATING EXPENSES.  Other operating expenses, which include
occupancy, travel and marketing expenses, decreased to 25% of revenue for 1995
from 28% for 1994. This decrease was a result of certain of these expenses
growing at a slower rate than revenue.
 
                                       15
 
<PAGE>
     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization decreased to
14% of revenue for 1995 from 16% of revenue for 1994. The decrease was the
result of the fixed nature of a large component of the depreciation and
amortization, which is the result of prior acquisitions, being measured against
a larger revenue base.
 
     WRITE-OFF OF ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT COSTS.  In
connection with the acquisition of CHAMP, the Company acquired CHAMP's ongoing
research and development activities. At the time of the acquisition, the Company
recorded a one-time charge resulting from the write-off of the acquired
in-process research and development costs. This charge totaled approximately
$12.2 million or 25% of the Company's revenue for 1995. These costs related to
the development of a client server based system to process and deliver health
care data and analysis tools to CHAMP customers. The amount of the one-time
charge was equal to the estimated current fair value, based on the risk adjusted
cash flows (at a discount rate of 20%, which included cost of capital of 18% and
an incremental risk premium of 2%), of specifically identified technologies for
which technological feasibility had not yet been established pursuant to
Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed," and for which
future alternative uses did not exist.
 
     INTEREST INCOME AND EXPENSE.  Net interest income was $1.1 million or 2% of
revenue for 1995 compared with net interest expense of $20,000 for 1994. The
increase in net interest income was the result of a portion of the proceeds of
the Company's public offerings being utilized to repay the amount due under the
Company's credit agreement with the Company's former majority stockholder, AMBAC
Inc. ("AMBAC") (approximately $1.9 million), with the balance being invested in
cash equivalents and short-term investments.
 
     INCOME TAXES.  The Company's effective income tax rate was (39)% for 1995
compared with 43% for 1994. The change was a result of the Company recording a
net loss in 1995.
 
1994 COMPARED TO 1993
 
     REVENUE.  Revenue for 1994 was $30.7 million, an increase of $2.6 million
or 9% over 1993. Effective January 1, 1994, the Company divested certain of its
software product lines which generated revenue of approximately $3.0 million
during 1993. After eliminating the revenue from these product lines, revenue for
1994 increased by $5.6 million or 22% over 1993. Revenue increased in both of
the Company's product classifications. The increase in Decision Support Systems
revenue was primarily due to increased sales of high-end Decision Support
Systems, offset by a decrease in sales of certain entry-level Decision Support
Systems which the Company is no longer actively marketing. Syndicated Product
revenue increased primarily as a result of the increased penetration of existing
products and the introduction of new products, including THE OUTPATIENT
UTILIZATION PROFILE and THE DIRECTORY OF HEALTH CARE PROFESSIONALS.
 
     SALARIES, WAGES AND BENEFITS.  Salaries, wages and benefits decreased to
50% of revenue for 1994 from 51% for 1993. This decrease was a result of the
leveraging of the Company's historical investments in technology and basic
infrastructure as revenue increased. However, during 1994, the Company continued
to increase its investment in sales and marketing personnel at a rate in excess
of revenue growth in order to expand the market penetration of existing systems
and products and to allow for the introduction of new systems and products.
 
     OTHER OPERATING EXPENSES.  Other operating expenses, which include
occupancy, travel and marketing expenses, were 28% of revenue for 1994 and 1993.
Decreases in outside data processing and travel costs were offset by slightly
higher marketing and occupancy costs.
 
     PROVISION FOR DOUBTFUL ACCOUNTS.  The provision for doubtful accounts
decreased to less than 1% of revenue for 1994 from 2% for 1993. This decrease
was a result of enhanced credit and collection processes and additional
personnel resulting in reduced bad debt losses.
 
     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization was 16% of
revenue for 1994 and 1993. The depreciation and amortization is primarily
related to the Company's acquisitions and certain capitalized costs related to
the development of methodologies, clinical measurement tools and technical
resources.
 
     INCOME TAXES.  During 1994 and 1993, the Company's effective tax rates were
43% and 51%, respectively. These rates were in excess of statutory rates
primarily as a result of the non-deductibility of the amortization of certain
goodwill. The reduction in the effective rate was primarily due to the increased
earnings of the Company resulting in a reduced impact of the amortization of
certain goodwill.

     The Company has experienced quarterly fluctuations in operating results,
which it expects to continue for the foreseeable future. During the three months
ended December 31, 1995, the Company recorded a one-time charge related to
acquired in-process research and development costs in connection with the CHAMP
acquisition. In addition, during the three months ended June 30, 1996, the
Company recorded a $4.4 million one-time charge related to acquired in-process
research and development costs in connection with the Response acquisition.
Similarly, the Company expects to incur a $41.2 million charge in connection
with the LBA acquisition during the three months ended September 30, 1996.
Quarterly results are also influenced by the annual availability of certain data
sources, which affects the timing of the release of certain Syndicated Products
and entry-level Decision Support Systems. As a result, the Company generally
recognizes greater revenue from sale of these systems and products during the
second and third quarters of each year.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     In February 1995, the Company completed an initial public offering of
2,012,500 shares of Common Stock at an initial public offering price of $14.00
per share. The net proceeds to the Company from the offering were approximately
$25.7 million. The Company utilized approximately $1.9 million of the proceeds
to repay amounts due to AMBAC under a line of credit. During August 1995, the
Company completed an additional offering of 1.5 million shares of Common Stock
at a price of $28.50 per share. The net proceeds to the Company were
approximately $40.3 million. In May 1996, the Company issued 261,951 shares at a
price of $51.00 per share pursuant to the exercise of an over-allotment option
granted by the Company to the underwriters in connection with the sale of all of
the shares of Common Stock owned by AMBAC and its wholly owned subsidiary, AMBAC
Indemnity Corporation ("AIC"). The net proceeds to the Company from the exercise
of the over-allotment option were approximately $12.8 million.
    
 
   
     On August 8, 1996, the Company obtained from First Union a credit facility
totalling $100 million, consisting of a $50 million term loan and a $50 million
revolving line of credit. The Company incurred a one-time facility fee of
$500,000 and is also required to pay a commitment fee on the average daily
unused portion of the facility at a rate ranging from 0.25% to 0.375% per annum,
depending on the Company's debt/cash flow ratio. Borrowings bear interest at
varying rates based on an index tied to First Union's prime rate or LIBOR
(currently 8.75%). The Company has drawn down the entire $50 million term loan
and approximately $36 million of the revolving line of credit in connection with
the LBA acquisition and will repay these borrowings with a portion of the net
proceeds to the Company of the Offering. The Company will then maintain a $50
million revolving line of credit for general corporate purposes, including
future acquisitions and working capital requirements. Borrowings are
collateralized by substantially all of the Company's assets. The credit facility
also contains financial covenants applicable to HCIA, including a debt/cash flow
ratio and ratios of debt to capital. The Company was in compliance with these
covenants after drawing on the credit facility and expects to continue to be in
compliance thereafter.
    
 
   
     During 1993, 1994, 1995 and the six months ended June 30, 1996, the Company
generated net cash from operations of approximately $2.4 million, $4.4 million,
$3.1 million and $3.7 million, respectively. During 1995 and the six months
ended June 30, 1996, approximately $7.3 million and $6.8 million of cash
generated from operations was used to fund the increase in accounts receivable.
The increases in accounts receivable were primarily the result of revenue
growth, as well as the timing of receipt of payments from certain major
customers. During 1995, approximately $1.7 million of cash generated from
operations was used to fund the decrease in deferred revenue, which was the
result of the timing of delivery of products to Datis customers subsequent to
the acquisition of Datis by the Company, as well as a decrease in the revenue
from product lines generating a significant portion of the historical deferred
revenue balance. Net cash provided by financing activities during 1993, 1994,
1995 and the six months ended June 30, 1996 was approximately $3.7 million,
$568,000, $66.2 million and $12.4 million, respectively, primarily as a result
of borrowings under the line of credit from AMBAC, the issuance of preferred
stock to AMBAC and AIC (subsequently exchanged for shares of Common Stock) and
the Company's public offerings in February and August 1995 and May 1996. The net
cash provided by operations and financing activities has been utilized primarily
for capital expenditures and acquisitions.
    
 
   
     The Company made capital expenditures (including capitalized leases)
totaling $2.0 million, $1.6 million, $3.1 million and $2.4 million during 1993,
1994, 1995 and the six months ended June 30, 1996, respectively. As of June 30,
1996, the Company had net working capital of $42.0 million, including cash, cash
equivalents and short-term investments in the amount of $26.1 million, and did
not have any material commitments for capital expenditures.
    
 
     In March 1995, the Company completed the acquisition of substantially all
of the assets of John Froehlich Associates for the payment of approximately
$520,000 in cash and the issuance of a note payable in the amount of $480,000,
which was paid in full in February 1996. In April 1995, the Company acquired
certain assets from MetriCor Inc. for a payment of $485,000 in cash and the
assumption of certain liabilities. Also in April 1995, the Company completed the
acquisition of all of the outstanding capital stock of Datis. The purchase price
for the capital stock of Datis was approximately $14.6 million in cash, which
included approximately $14.25 million funded by the Company and $386,000 funded
with the proceeds received from the exercise of certain options to
 
                                       18
 
<PAGE>
purchase Datis stock. In addition, the Company repaid approximately $900,000 of
outstanding debt of Datis. In December 1995, the Company acquired the CHAMP unit
of Mercer for $17.5 million in cash and, in May 1996, the Company completed the
acquisition of Response for approximately $6.2 million in cash. Each of these
acquisitions has been accounted for using the purchase method of accounting and,
accordingly, the assets have been valued at their estimated fair market value.
Funding for the acquisitions was provided by the proceeds of the Company's
public offerings and cash generated by operations.
 
   
     The Company expects to incur additional costs of $7 to $10 million to
complete the development efforts related to systems and products obtained in
connection with the acquisitions of CHAMP, Response and LBA, and to integrate
these products with the Company's other products. Such costs are expected to
consist of direct labor and contracted labor costs and are expected to be
incurred over the next two to three years.
    
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
     In October 1995, Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-based Compensation" ("SFAS No. 123"), was issued. This
statement requires the fair value of stock options and other stock-based
compensation issued to employees to either be included as compensation expense
in the income statement, or the pro forma effect on net income and earnings per
share of such compensation expense to be disclosed in the footnotes to the
Company's consolidated financial statements commencing with the Company's 1996
fiscal year. The Company expects to adopt SFAS No. 123 on a disclosure basis
only. As such, implementation of SFAS No. 123 is not expected to impact the
Company's consolidated financial statements.
 
     In March 1995, Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of " ("SFAS No. 121"), was issued. This statement establishes
accounting standards for the impairment of long-lived assets, certain
identifiable intangibles, and goodwill related to those assets to be held and
used for long-lived assets and certain identifiable intangibles which are to be
disposed. Implementation of SFAS No. 121 is not expected to have a material
impact on the Company's consolidated financial statements.

GENERAL
 
     HCIA is a leading health care information content company that develops and
markets integrated clinical information systems and products. The Company's
systems and products range from standardized data bases to highly focused
Decision Support Systems that assist its customers in evaluating the efficacy
and economics of health care delivery. HCIA currently sells its Decision Support
Systems to more than 325 customers, including hospitals, integrated delivery
systems, self-insured employers, pharmaceutical companies and managed care
organizations. The Company's Syndicated Products are sold to over 7,000
customers. As a result of its unique ability to integrate health care data
collected from numerous sources and across varied treatment settings, the
Company believes that it is well positioned to offer the information systems and
products necessary to continue to increase average revenue per customer through
the sale of more sophisticated and comprehensive Decision Support Systems. The
Company's marketing and pricing strategies are focused on the generation of
recurring revenue from Decision Support Systems through multi-year agreements
(typically two to three years) and through the renewal of its Syndicated
Products, which are updated annually. During 1995, approximately 69% of the
Company's revenue was recurring in nature. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Overview."
 
     By utilizing its core collection of proprietary data standardization
methodologies, value-added clinical measurement tools and data bases, including
the ICCS System(TM), HCIA creates clinical information systems and products from
its many large and disparate data streams. The ICCS System(TM) allows for the
standardization and comparison of detailed clinical data across a broad range of
data sources. The Company's proprietary disease management methodologies link
the costs, quality, utilization and outcomes of medical services delivered to
patients in various clinical settings. These methodologies and technical
resources permit the Company to provide a level of clinical information which is
substantially more detailed and useful in modifying clinical practice patterns
than information derived from traditional health care data sources.

RECENT ACQUISITIONS
 
   
     LBA HEALTH CARE. On August 9, 1996, the Company acquired LBA for
approximately $130 million. LBA, which had revenue during the year ended
December 31, 1995 and the six months ended June 30, 1996 of approximately $16.6
million and $14.4 million, respectively, is a provider of health care
information products and services that combine data collection, benchmarking and
decision support tools to identify and quantify cost reduction and quality
improvement opportunities in clinical settings. LBA's principal products,
including its VALUE ENHANCEMENT systems and Health Care Financing Administration
("HCFA") Centers of Excellence program, utilize comparative data base analyses
and a clinical implementation management team to assist customers in reducing
clinical resource consumption and improving outcomes in specific practice areas,
such as orthopaedics and cardiology. LBA's proprietary data bases contain
detailed data on cost, quality, clinicial resource consumption and
labor/productivity obtained from approximately 250 providers and provider groups
that are LBA customers. The level of information contained in LBA's data bases
is similar to HCIA's ICCS-level data base. HCIA plans to utilize its ICCS
System(TM) to standardize the LBA data bases and integrate them with the
ICCS-level data base.
    
 
     LBA's systems enable its customers to achieve significant cost savings by
(i) improving quality of outcomes, (ii) reducing clinical resource consumption
and (iii) optimizing labor utilization. The Company believes that LBA's clinical
implementation methodologies will significantly enhance its ability to deliver
clinical solutions that identify and quantify cost reduction and quality
improvement opportunities. Typical LBA customers spend approximately $75,000 to
$100,000 per year on VALUE ENHANCEMENT systems, and approximately 75% of LBA's
customers have purchased at least two systems. As part of a VALUE ENHANCEMENT
system, LBA guarantees that each customer will achieve a cost savings at least
equal to the fees paid to LBA.
 
   
     Pursuant to the acquisition agreement, the Company acquired all of the
capital stock of LBA's parent company, HealthVISION, Inc. ("HealthVISION").
Prior to the acquisition, all of the assets and liabilities of HealthVISION not
associated with LBA were distributed to certain then-current stockholders of
HealthVISION. The purchase price for the acquisition was approximately $130
million (which included the payment of certain
    
 
                                       20
 
<PAGE>
   
liabilities, including bank debt and management bonuses), $100 million of which
was paid in cash and $30 million of which was paid by the delivery of 492,961
shares of Common Stock of HCIA. The Company utilized $86 million in borrowings
under a credit facility with First Union to fund the cash portion of the
purchase price, which the Company intends to repay with a portion of the net
proceeds to the Company of the Offering. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources." Pursuant to the acquisition agreement, the Company has
agreed to file and maintain under the Securities Act a shelf registration
statement for the benefit of certain former stockholders of HealthVISION.
    
 
     RESPONSE HEALTHCARE. In May 1996, the Company acquired all of the
outstanding capital stock of Response for approximately $6.2 million in cash.
Response, which had revenue of approximately $2.6 million for the year ended
December 31, 1995, specializes in capturing and analyzing point-of-care,
patient-centered data relating to disease-specific outcomes measurement,
member/patient satisfaction and functional status, as well as the development of
Internet applications. Response's primary customers include managed care
organizations and pharmaceutical companies.
 
INDUSTRY BACKGROUND
 
     Market driven efforts to contain rising health care costs have resulted in
an increasing demand for access to sophisticated heath care information. During
the five years ended in 1995, the average annual increase in U.S. health care
expenditures was approximately double the rate of general inflation as measured
by the Consumer Price Index. It is estimated that health care expenditures
exceeded $1 trillion, or approximately 14% of U.S. Gross Domestic Product, in
1995. Historically, cost containment efforts have focused on controlling
administrative costs even though approximately 65% of health care costs are
related to the clinical delivery of care (i.e., the costs directly associated
with the treatment of illness).
 
     Clinical costs are driven by the choice of therapeutic resources and the
intensity and frequency of the delivery of such resources. The inappropriate or
excess consumption of therapeutic resources is referred to as "clinical
inefficiency." Clinical inefficiency manifests itself in many ways, including
clinically unjustified lengths of stay, excessive readmission rates,
above-average clinical complication and mortality rates, and excessive primary
care physician referrals to specialists.
 
     Efforts to measure and control the clinical costs of health care
traditionally have been hampered by the lack of "benchmark" data required to
study the appropriateness, efficiency and effectiveness of health care delivery.
Structural changes and industry consolidation are driving the major health care
constituencies (providers, buyers and suppliers) to utilize information and
analytical tools to better measure clinical effectiveness. The increased
industry emphasis on "outcomes measurement" and "disease management" reflects
recognition of the need to properly understand and evaluate clinical costs.
 
     Each of the major health care constituencies demands clinical information
for different reasons. In order to compete more effectively, providers are
increasingly demanding information that allows them both to measure the cost,
quality and outcome of the care they are delivering and to "benchmark" data to
measure performance against the industry's best practices. Buyers are
increasingly demanding a quality outcome at a fixed or capitated price for a
bundle of medical services. As a result, the overall efficiency and
effectiveness of the services delivered has become the central issue in the
selection of providers and in the continued analysis of the performance of
existing providers. Suppliers are increasingly required to demonstrate the
clinical and economic utility of their products when compared with alternatives
because of the increasing emphasis on costs and efficiency and the growing use
of mechanisms such as formularies to restrict physician drug choice.

BUSINESS STRATEGY
 
     HCIA's strategy is to maintain and extend its position as a leading
provider of content-based clinical information systems and products to all
market constituencies. Key elements of the Company's strategy are to:
 
     BUILD RECURRING REVENUE. HCIA's marketing and pricing objectives are
focused on the generation of recurring revenue through multi-year contracts and
annually renewable contracts, as well as regular sales and updates of its
Syndicated Products. The Company's recurring revenue percentage for 1995 was
approximately 69%. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Overview." The Company believes that the
high level of sophistication of its systems and products, combined with the
costs associated with switching to substitute information suppliers, encourage
its customers to continue their relationships with HCIA.
 
     EXPAND THE SIZE AND SCOPE OF CUSTOMER RELATIONSHIPS. As a result of its
unique ability to integrate health care data collected from numerous sources and
across varied treatment settings, the Company believes that it is
well-positioned to offer the information systems and products necessary to
continue to increase average revenue per customer through the sale of more
sophisticated and comprehensive Decision Support Systems. The demand for more
sophisticated health care information systems and products has been driven by
the recognition of the need for more comprehensive information on costs,
outcomes and utilization to assess and manage risk while improving the quality
of care.
 
     DEVELOP AND ACQUIRE NEW DATA RESOURCES AND TECHNOLOGIES. HCIA seeks to
develop and acquire new methodological, analytical and technical resources that
will continue to enhance the Company's ability to deliver clinical solutions. In
addition to its internal product development efforts, the Company seeks to
continue the acquisition of other data resources and technologies. The Company
intends to integrate and leverage these assets into product-line extensions
across its markets. The Company believes that its management and product-line
infrastructures, as well as its historical success in acquiring and assimilating
new products and companies, will allow it to continue the successful development
and acquisition of new systems and products.
 
     DEVELOP STRATEGIC RELATIONSHIPS WITH KEY INDUSTRY PARTICIPANTS. HCIA seeks
to transcend the traditional customer-vendor relationship and forge long-term
alliances with key industry participants that are driving market evolution in
the health care industry. Through its strategic relationships with industry
leaders, the Company can add substantial value to its information systems and
products and promote the Company's proprietary data bases and methodologies as
an industry standard.
 
SYSTEMS AND PRODUCTS
 
   
     HCIA's information systems and products are broadly classified as Decision
Support Systems, which contributed approximately 80% and 81% of revenue for 1995
and the six months ended June 30, 1996, respectively, and Syndicated Products,
which contributed approximately 20% and 19% of revenue for the same respective
periods. The Company offers its information systems and products through a
variety of media and distribution channels, including print, magnetic media,
CD-ROM and on-line access through SoleSource(TM), its client/server workstation.
    
 
  DECISION SUPPORT SYSTEMS
 
     HCIA offers a range of Decision Support Systems, which are utilized by the
three major health care market constituencies:
 
       PROVIDERS, such as hospitals, physician groups and integrated delivery
systems, use the Company's Decision Support Systems to measure and analyze the
cost and quality of medical interventions. The Company's entry-level Systems
provide customers with competitor specific information such as market share by
specialty, local market utilization rates compared with regional and national
norms and customer specific analyses of product line and physician level
resource consumption. High-end Decision Support Systems incorporate benchmarks
for specific medical resource consumption and are designed to help providers
understand the best practice for a medical intervention.
 
                                       22
 
<PAGE>
       BUYERS, such as managed care organizations, indemnity insurers and
self-insured employers, utilize the information and analyses on medical resource
usage and outcomes derived from the Company's Decision Support Systems to select
and monitor the performance of network providers, channel specific types of
patients towards the most clinically effective providers, and negotiate fair
prices and appropriate utilization criteria, as well as to manage the overall
health status of a covered population. The acquisitions of CHAMP and Response
have increased the Company's access to self-insured employers and managed care
organizations.
 
       SUPPLIERS, such as pharmaceutical, biotechnology and medical supply and
device companies, utilize the Company's Decision Support Systems in market
analysis, product positioning and pharmacoeconomic analysis. Pharmacoeconomic
analysis provides suppliers with information needed to measure the specific
benefit/cost and outcome of an individual product against those of competing
products, alternative therapies or, in the case of a new drug or product, the
STATUS QUO therapy.
 
     The Company's entry-level Systems are generally priced from $25,000
annually, while high-end Systems are generally priced from $250,000 to more than
$1.0 million annually. HCIA has entered into a number of strategic relationships
with state hospital associations, business partners such as HBO & Company
("HBOC"), and large users of data such as CIGNA Healthcare, Amgen Inc. and
Columbia/HCA.

     HCIA's Decision Support Systems are based on the Company's DataBridge(TM)
collection of data bases and data handling technologies and SoleSource(TM)
desktop analytical software, and are supplemented by its clinical implementation
management team.

     DATABRIDGE.(TM)  DataBridge(TM) is HCIA's collection of proprietary data
bases and data-handling technologies. A typical Decision Support System customer
submits data in an electronic, computer-readable format. In creating the
interface for the customer's data stream, HCIA enables the transfer of customer
data and the subsequent application of the Company's proprietary software
algorithms and data-standardization technologies to the incoming data,
transforming the data into HCIA's proprietary standardized formats.
DataBridge(TM) has several components, including:

       DATA BASE. A large number of the Company's customers are also its data
suppliers. Most of the Company's Decision Support System contracts provide that
as the Company extracts data from the customer (as part of the process of
delivering a system to the customer), the data become part of the Company's data
base. The Company supplements its data base with data it purchases or licenses
from federal and state governments, trade groups and other industry sources. The
Company maintains more than a terabyte of live health care data, including data
from medical records, laboratory, pharmacy, imaging, outpatient clinics,
physician's offices, insurance claims, managed care encounters and point-of-care
member patient surveys.

     The Company's data base resides in a relational data base structure that
utilizes a network of large Sun Microsystems servers. The Company believes that
its current software and hardware platforms are scaleable and provide it with a
cost and flexibility advantage. The Company has made a significant investment in
an open-network architecture which links its several geographical locations and
provides customers with leased-line and dial-up access. The Company supports
most of the major relational data base platforms, such as Informix, Oracle, DB2,
Sybase and SQL Server.
 
     The Company has personnel drawn from several key health care disciplines
(e.g., pharmacists, clinical nurses and medical technologists) who are
responsible for the auditing, editing and standardizing of its data base, as
well as the upgrading and maintaining of its core methodologies. The Company
believes that its data base provides more clinical detail and better outcomes
measurement capabilities than competitive systems. Furthermore, the detailed
medical content of the data and HCIA's experience in collecting and
standardizing this information provide additional competitive advantages.
 
   
     The acquisitions of the CHAMP and Response data bases have significantly
expanded the Company's outpatient and episode-of-care capabilities. The recent
acquisition of LBA should significantly expand the Company's ICCS-level data
base through the addition of detailed clinical data from approximately 250
providers and provider groups which are LBA customers. As a result of
acquisitions and its internal growth, the Company believes that it has built one
of the largest and most sophisticated collections of integrated clinical,
financial and labor/productivity data in the health care industry.
    
 
                                       23
 
<PAGE>
       ICCS SYSTEM.(TM) The Company holds a perpetual and exclusive license to
the ICCS System(TM), subject only to the Company's obligation to use all
commercially reasonable efforts to maintain and upgrade the system. The ICCS
System(TM) assigns a discrete and clinically detailed 12-digit code to every
product and service consumed in the treatment of patients. The Company believes
that the ICCS System(TM) is the health care industry's most widely implemented
uniform classification system for tracking and measuring the use of medical
resources (e.g., drugs, devices, laboratory tests, blood units, diagnostic
imaging and clinical services) across health care providers. The ICCS System(TM)
allows for the standardization and comparison of detailed clinical data,
regardless of the original source of the data (e.g., medical records, insurance
claims, laboratory or pharmacy systems). As of December 31, 1995, there were
more than 69,600 separate ICCS codes, and, during the 12 months ended December
31, 1995, more than 4,100 new codes were added to the ICCS System(TM).

     The ICCS System(TM) is used by the Company to create the most clinically
detailed portion of its data base. The Company develops a set of proprietary
software interfaces with each customer who is a supplier of such data. The
interfaces are built by a series of proprietary "data-mapping" applications that
incorporate the ICCS System(TM) and a series of algorithms that allow the
mapping applications to "learn" each time a new clinical item is encountered. In
doing so, the applications are able to automatically standardize more data each
time a new interface is created. As the volume of ICCS-level data entering the
data base expands, the efficiency of the interface-creation process increases.
In 1990, the Company typically required more than six months to create an
interface to extract ICCS-level data. With more than 175 interfaces created to
date, the typical interface creation process has been reduced to less than six
weeks.

     Set forth below is an illustration of the application of the ICCS
System(TM) to the delivery of a common anti-infective drug.

</TABLE>
 
     SOLESOURCE.(TM) SoleSource(TM) is the Company's workstation that provides
customers with access to and analyses of information obtained with a Decision
Support System. SoleSource(TM) utilizes Microsoft Foundation Classes Software
and accesses a variety of data base configurations, including Microsoft SQL
Server, Microsoft Access and Informix. As the Company has worked with a variety
of different health care organizations during the last several years (e.g.,
hospitals, managed care organizations and pharmaceutical companies), it has
developed an extensive library of proprietary health care data base
applications. In addition, as a result of the CHAMP, Response and LBA
acquisitions, the Company has recently expanded, and will continue to expand,
the scope of its data base applications. Depending on the customer, the size of
the data base and the sophistication of the Decision Support System, the Company
licenses various SoleSource(TM) applications to customers as part of a Decision
Support System.

     CLINICAL IMPROVEMENT METHODOLOGY AND MANAGEMENT. In addition to providing
data bases and application software, the Company, utilizing proprietary
methodologies, assists customers with the implementation of clinical solutions.
The Company's knowledge-based clinical improvement methodologies allow HCIA to
leverage its ICCS-level information and enable clients to realize improved
clinical outcomes and lower costs through

                                       24

<PAGE>
the modification of medical and behavioral practice patterns. The Company's
methodologies link the costs, quality, utilization and outcomes of medical
services delivered to patients in various clinical settings and focus on
episodes of illness that offer the greatest opportunity for improving outcomes
and reducing costs.

     As a result of the LBA acquisition, the Company will significantly expand
its clinical improvement methodologies and implementation management
capabilities. The Company also intends to integrate LBA's data bases,
methodologies and staff with HCIA's, creating additional leverage from its
ICCS-level data base and SoleSource(TM) delivery platform. LBA's VALUE
ENHANCEMENT systems utilize data base analyses, clinical improvement
methodologies and an implementation management team of approximately 50 people
to assist customers in reducing clinical resource consumption and improving
outcomes in major specialties, including:

<TABLE>
<S>                                                <C>
(Bullet) invasive cardiovascular                   (Bullet) vascular

(Bullet) medical cardiology                        (Bullet) women's services
</TABLE>

     In addition to its VALUE ENHANCEMENT systems, LBA assists hospitals in
obtaining Center of Excellence designation by HCFA. Center of Excellence
designation by HCFA conveys select medical status to high volume, premier
facilities in the practice areas of cardiology and orthopaedics. LBA's Centers
of Excellence program provides the necessary metrics, methodologies and data
bases to assist hospitals in achieving Center of Excellence designation for
specific clinical practice areas. The Company intends to enhance LBA's Centers
of Excellence program following the acquisition and believes that it will be
uniquely positioned to work with hospitals in motivating physicians and other
clinical practitioners to change behavior and achieve measurable improvements in
costs, outcomes, and clinical resource consumption -- the fundamental
requirements for Center of Excellence designation.

  SYNDICATED PRODUCTS

     Syndicated Products include publications and standardized databases which
are generally priced between $100 to $2,000, with certain Products priced up to
$25,000. The Products are developed from specific portions of the Company's data
base, and feature particular industry niches. Most Syndicated Products are sold
as annually renewable subscriptions or as multi-year contracts. Syndicated
Products range from data base directories (e.g., health care industry
professionals, nursing homes and managed care organizations) to more complex
analyses (e.g., cost and outcome summaries for each U.S. hospital).

     HCIA also markets to managed care clients a number of more sophisticated
Syndicated Products containing national and regional normative data on length of
stay, costs and medical necessity. The Company markets these products directly
to managed care organizations, and through alliances with information systems
vendors, third-party administrators and other entities that process data streams
for managed care organizations and payors. These Syndicated Products generally
are used for utilization management, claims adjudication and actuarial
forecasting and generally result in annual revenue of $100,000 or more per
customer.

CUSTOMERS

     The Company's customers include numerous health care industry participants
located throughout the United States and the United Kingdom, including major
provider and provider groups, managed care organizations, and pharmaceutical,
biotechnology and medical device companies. As of December 31, 1995, the Company
had more than 325 Decision Support System customers and more than 7,000
Syndicated Product customers. In 1994, one customer, Amgen Inc., accounted for
approximately 12% of the Company's revenue. In 1995, no single customer
accounted for 10% or more of the Company's revenue. HCIA's ten largest customers
accounted for approximately 29% and 36% of its revenue during 1994 and 1995,
respectively.

SALES AND MARKETING
 
     HCIA markets its information systems and products through a variety of
means that are designed to enhance its name recognition and facilitate the
marketing of additional systems and products to its customer base. The Company
utilizes a direct sales approach with the existing customer base to market its
Decision Support Systems. The Company's field sales force is highly specialized
and frequently draws on the Company's clinical implementation management team.
The field sales force seeks to present proposals in face-to-face meetings at the
executive level. In addition, HCIA has recently entered into agreements with
HBOC, Transition Systems and ActaMed, whereby the Company's Systems are marketed
through their respective sales forces.
 
     The Company also approaches each of the major market constituencies through
the sale of lower-priced Syndicated Products. Many of these products, such as
the 100 TOP HOSPITALS study, are specifically designed to increase the
visibility of the Company as an industry-leading source of health care
information. The Company uses both telemarketing and direct-mail efforts in the
sales of its Syndicated Products.
 
     HCIA continually seeks opportunities to create name recognition as a
leading provider of health care information. As part of this strategy, the
Company is widely quoted in the media, including publications such as THE WALL
STREET JOURNAL and MODERN HEALTHCARE, and its senior officers are frequently
asked to speak at industry conferences and serve on the editorial boards of
industry newsletters and publications.
 
COMPETITION
 
     The Company believes that the principal competitive factors in the health
care information market are the breadth and quality of system and product
offerings, access to proprietary data, the proprietary nature of methodologies
and technical resources, price and the effectiveness of marketing and sales
efforts. In addition, the Company believes that the speed with which information
companies can anticipate and respond to the evolving health care industry
structure and identify information needs is an important competitive factor. The
Company believes that it competes favorably with respect to each of these
factors.
 
     The market for health care information products and services is intensely
competitive. Competitors vary in size and in the scope and breadth of products
and services offered, and the Company competes for the sale of systems and
products and the resulting access to data with different companies in each of
its target markets. Many of the Company's competitors have significantly greater
financial, technical, product development and marketing resources than the
Company. Furthermore, other major information companies not presently offering
clinical health care information services may enter the markets in which the
Company competes.
 
     The Company's potential competitors include specialty health care
information companies, health care information system and software vendors and
large data processing and information companies. Many of these competitors have
substantial installed customer bases in the health care industry and the ability
to fund significant product development and acquisition efforts.
 
INTELLECTUAL PROPERTY
 
     HCIA considers its methodologies, computer software and data bases to be
proprietary. The Company seeks to protect its proprietary information through
confidentiality agreements with its employees. The Company's policy is to have
employees enter into confidentiality agreements containing provisions
prohibiting the disclosure of confidential information to anyone outside the
Company, requiring employees to acknowledge, and, if requested, assist in
confirming the Company's ownership of any new ideas, developments, discoveries
or inventions conceived during employment, and requiring assignment to the
Company of proprietary rights to such matters that are related to the Company's
business.
 
     The Company also relies on a combination of trade secret, copyright and
trademark laws, contractual provisions in agreements with customers and
technical measures to protect its rights in various methodologies, systems and
products and data bases. The Company has not filed any patent applications or
copyright registration applications covering its software technology. Due to the
nature of its software applications, the Company believes that patent, trade
secret and copyright protection are less significant than the Company's ability
to further develop, enhance and modify its current systems and products.

GOVERNMENT REGULATION
 
   
     The FDA has promulgated a draft policy for the regulation of certain
computer products as medical devices. Although it is not possible to anticipate
the final form of the FDA's policy with regard to computer software, the Company
expects that, whether or not the draft policy is finalized, the FDA is likely to
become increasingly active in regulating computer software that is intended for
use in health care settings. The Company's products and product development
activities, therefore, could become subject to extensive regulation by the FDA.
The FDA regulates the introduction of new medical devices as well as activities
such as manufacturing, labeling and recordkeeping for such products. To the
extent that computer software is a medical device under FDA regulations or
policy, the Company would be required, depending on the product, to comply with
regulations, to (i) register and list the product with the FDA, (ii) notify the
FDA and demonstrate substantial equivalence to other products on the market
before marketing such products or (iii) obtain FDA approval by demonstrating
safety and effectiveness before marketing a product. In addition, such products
would be subject to the FDA's general controls, including those relating to good
manufacturing practices and adverse experience reporting.
    
 
   
     The process of obtaining clearance from the FDA can be costly and time
consuming, and there can be no assurance that, if required, such clearance would
be granted for the Company's existing and future products on a timely basis, if
at all, or that FDA review will not include delays that would adversely affect
the Company's ability to market new products or to expand permitted uses of
existing products. The FDA could also limit or prevent the manufacture or
distribution of the Company's products and has the power to require the recall
of such products. FDA regulations depend heavily on administrative and
scientific interpretation, and there can be no assurance that future
interpretation made by the FDA or other regulatory bodies, with possible
prospective and retroactive effect, will not adversely affect the Company.
    
 
     The confidentiality of patient records and the circumstances under which
such records may be released for inclusion in the Company's databases is subject
to substantial regulation by state governments. These state laws and regulations
govern both the disclosure and use of confidential patient medical record
information. Although compliance with these laws and regulations is principally
the responsibility of the hospital, physician or other health care provider
supplying the data to the Company, the Company's databases have been designed to
enable health care providers to comply with the confidentiality of state law.
The Company believes that its procedures comply with the laws and regulations
regarding the collection of patient data in substantially all jurisdictions.
However, additional legislation governing the dissemination of medical record
information has been proposed at both the state and federal level. This
legislation may require holders of such information to implement security
measures that may be of substantial cost to the Company. There can be no
assurance that changes to state or federal laws will not materially restrict the
ability of health care providers to submit information from patient records to
the Company.
 
EMPLOYEES
 
     As of June 30, 1996, the Company had 588 employees, including 59 in sales
and marketing, 335 in health care data, 110 in technology and 84 in finance and
administration. None of the Company's employees are represented by a union or
other bargaining group. The Company believes its relationships with its
employees to be satisfactory. As of June 30, 1996, LBA had 162 employees, none
of whom are represented by a union or other bargaining group.
 
PROPERTIES
 
   
     The Company's executive and corporate offices are located in Baltimore,
Maryland, in approximately 57,000 square feet of leased office space, under a
lease that expires on December 31, 2002, and which includes an option for an
additional term of up to five years. The Company also leases approximately
36,500 square feet of office space in Ann Arbor, Michigan, under a lease that
expires on March 31, 2000. The Company also maintains seven other offices in the
United States and three offices in Europe. LBA maintains corporate offices in
Denver, Colorado, in approximately 41,962 square feet of leased office space
under a lease that expires in September 2001. The Company believes that its
facilities are adequate for its current operations.

EMPLOYMENT AGREEMENT
 
     Effective as of January 1, 1995, the Company entered into an employment
agreement with Mr. Pillari pursuant to which the Company continued his
employment as Chairman of the Board, President and Chief Executive Officer.
Pursuant to the employment agreement, Mr. Pillari receives an annual base salary
of $265,000 and is entitled to participate in bonus arrangements under which he
is eligible to earn an annual bonus based on the Company's achieving certain
performance goals to be established by the Board of Directors. The employment
agreement has an initial term of two years, and unless the Board of Directors
notifies Mr. Pillari otherwise, the term of the agreement automatically renews
daily for succeeding two year periods.
 
     The employment agreement provides that in the event of the termination of
Mr. Pillari's employment for certain reasons, including certain terminations
resulting from a change in control of the Company (as defined in the employment
agreement), Mr. Pillari would be entitled to receive for the remainder of the
employment term contemplated in the agreement, compensation at an annualized
rate equal to the sum of his base annual salary and target bonus at the time of
termination (such sum being not less than 140% of such base annual salary). In
addition, he would continue to participate in all Company benefit plans until
the earlier of two years from the date of termination or such time as he is
covered by a comparable plan of a subsequent employer. Mr. Pillari is also
subject to certain restrictions under the agreement prohibiting him from
competing with the Company or any of its subsidiaries and from divulging any
confidential proprietary information obtained by him while in the employ of the
Company and for a period of time thereafter.
 
MANAGEMENT RETENTION AGREEMENTS
 
     The Company has entered into a management retention agreement with each of
its officers (other than Mr. Pillari). These agreements provide for payments and
other benefits if there is a change in control (as defined in the agreement) of
the Company and, within two years of such change in control, the officer's
employment is
 
                                       29
 
<PAGE>
terminated by the Company or its successor other than for cause (as defined in
the agreement), or the officer resigns for good reason (as defined in the
agreement). Under each agreement, the officer would receive, following
termination of employment under such circumstances, cash payments equal to two
times the sum of (i) the officer's highest annual rate of base salary, and (ii)
the product of the officer's highest bonus percentage (as a percentage of base
salary) times his highest base salary (such sum being the "Reference Amount").
The officer may elect to receive payment of one times the Reference Amount
either in a lump sum or in the form of periodic payments following his
termination of employment. Amounts in excess of one times the Reference Amount
will be made in the form of periodic payments, and will be subject to reduction,
on a dollar-for-dollar basis, by any compensation the officer earns from a
subsequent employer unrelated to the Company.
 
     In addition to the payments described above, the officer would be fully
vested in all stock options and other Awards under the HCIA 1994 Stock and
Incentive Plan (the "Stock Option Plan") upon a change in control and would
receive following termination of employment a lump-sum payment equal to the
amount that the Company would have contributed for the officer's account under
the Company's Savings Incentive Plan during the two years following termination
of employment. The officer and his family will remain eligible to participate in
the Company's medical and other welfare benefits programs for two years from the
officer's termination of employment (except that coverage will end to the extent
the officer begins coverage under the plans of a subsequent employer).
 
STOCK OPTIONS
 
     NON-PLAN OPTIONS.  The Company has granted non-qualified options (the
"Options"), pursuant to individual stock option award agreements, to certain of
its past and present employees (the "optionees") to purchase shares of the
Company's Common Stock. Options were granted in December 1992, and in February,
April and October 1994 (collectively the "Options"). The Options granted in
October 1994 expire on October 21, 2004. The remainder of the Options expire on
July 1, 2000.
 
     The Options have exercise prices ranging from $6.00 to $10.50 per share.
With respect to the Options granted in December 1992 and February and April
1994, 50% of the shares of Common Stock may be exercised on or after February
22, 1996 and the balance of the Options may be exercised on or after February
22, 1997. The Options granted in October 1994 become exercisable upon their
vesting, which is over a three-year period which commenced in October 1995.
Under the Options, if the optionee's employment with the Company terminates for
any reason other than death or permanent disability (as defined in the option
agreement), the Option shares not vested are forfeited. If the optionee's
employment terminates by reason of death or permanent disability prior to the
vesting of an Option, the Option is fully vested as of the date of death or
termination due to permanent disability. The Options granted in October 1994
also vest in full if the optionee's employment terminates due to retirement.
 
     The Company's Chief Executive Officer was granted, in connection with the
Company's initial public offering, a non-plan option to purchase 160,000 shares
of Common Stock at an exercise price equal to the initial public offering price
of $14.00 per share. This option is exercisable in full and will expire on
February 22, 2000.
 
   
     STOCK OPTION PLAN.  The Company's Stock Option Plan was approved by the
Board of Directors on December 22, 1994 and thereafter by the Company's
stockholders. The Stock Option Plan provides for the grant or award of stock
options, stock appreciation rights, restricted stock, restricted stock units and
other performance awards which may or may not be denominated in shares of Common
Stock or other securities (collectively, the "Awards"). Stock options granted
under the Stock Option Plan may be either incentive stock options or non-
qualified options. The purpose of the Stock Option Plan is to attract and retain
outstanding employees through the incentives of stock ownership and monetary
payments. Any regular full-time employee of the Company, including officers but
excluding directors who are not officers, is eligible to receive awards.
    
 
     The Stock Option Plan is administered by the Compensation Committee.
Subject to the provisions of the Stock Option Plan, the Compensation Committee
has the authority to designate participants, determine the types of Awards to be
granted, the number of shares to be covered by each Award, the time at which
each Award is exercisable or may be settled, the method of payment and any other
terms and conditions of the Awards. All Awards shall be evidenced by an Award
Agreement between the Company and the participant.
 
                                       30
 
<PAGE>
   
     While the Compensation Committee determines the prices at which options and
other Awards may be exercised under the Stock Option Plan, the exercise price of
an option shall be at least 100% of the fair market value (as determined under
the terms of the Stock Option Plan) of a share of Common Stock on the date of
grant. The aggregate number of shares of Common Stock available for awards under
the Plan is currently 1,350,000. No Awards may be made under the Stock Option
Plan after December 31, 2004.
    
 
   
     DIRECTORS OPTION PLAN. Under the HCIA 1995 Non-Employee Directors Stock
Option Plan (the "Directors Option Plan"), each director who is not an officer
or employee of the Company or its affiliates (an "outside director") is
initially granted an option to purchase 5,000 shares of Common Stock at an
exercise price equal to the fair market value of the Common Stock at the time of
grant. In addition, each current outside director, and each person who is
subsequently elected as an outside director, will be granted an option at each
annual meeting of stockholders to purchase 5,000 shares of Common Stock at an
exercise price equal to the fair market value on the date of grant. A total of
200,000 shares of Common Stock are currently available for awards under the
Plan.

                       PRINCIPAL AND SELLING STOCKHOLDERS
 
   
     The following table sets forth as of August 8, 1996, as adjusted to reflect
the sale of shares by the Company and the Selling Stockholders, certain
information with respect to the beneficial ownership of the Common Stock by: (i)
each of the Selling Stockholders; (ii) each person known by the Company to
beneficially own more than 5% of the Common Stock; (iii) each director and
executive officer of the Company; and (iv) all directors and executive officers
of the Company as a group. The Company believes that the beneficial owners of

     The Underwriters have advised the Company that they propose initially to
offer the shares of Common Stock to the public at the public offering price set
forth on the cover page of this Prospectus, and to certain dealers at such price
less a concession not in excess of $    per share. The Underwriters may allow,
and such dealers may reallow, a discount not in excess of $  per share to
certain other dealers. After the initial public offering, the public offering
price, concession and discount may be changed.
 
     The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of 332,505
additional shares of Common Stock at the public offering price set forth on the
cover page of this Prospectus, less the underwriting discount. The Underwriters
may exercise this option only to cover over-allotments, if any, made on the sale
of the shares of Common Stock offered hereby. If the Underwriters exercise this
option, each of the Underwriters will have a firm commitment, subject to certain
conditions, to purchase approximately the same percentage thereof which the
number of shares of Common Stock to be purchased by it shown in the foregoing
table is of the 2,216,696 shares initially offered hereby.
 
     The Company and certain officers of the Company and HealthVISION have
agreed not to offer, sell, contract to sell or otherwise dispose of, directly or
indirectly, or file or cause to be filed a registration statement under the
Securities Act with respect to, any shares of Common Stock, securities
convertible into, exchangeable for or repayable with such shares or rights or
warrants to acquire such shares, for a period of 90 days after the date of this
Prospectus without the prior written consent of Merrill Lynch, Pierce, Fenner &
Smith Incorporated, except that the Company may, without such consent, grant
options pursuant to the Stock Option Plan and the Directors Option Plan or issue

or file registration statements with respect to, up to a specified number of
shares of Common Stock in connection with acquisitions under certain
circumstances.
 
     In connection with the Offering, certain Underwriters (and selling group
members, if any) may engage in passive market making transactions in the Common
Stock on NASDAQ in accordance with Rule 10b-6A under the Exchange Act. Rule
10b-6A permits, upon satisfaction of certain conditions, underwriters and
selling group members participating in a distribution that are also NASDAQ
market makers in the security being distributed to engage in limited market
making transactions during the period when Rule 10b-6 under the Exchange Act
would otherwise prohibit such activity. Rule 10b-6A prohibits underwriters and
selling group members engaged in passive market making, generally, from entering
a bid or effecting a purchase at a price that exceeds the highest bid for those
securities displayed on NASDAQ by a market maker that is not participating in
the distribution. Under Rule 10b-6A, each underwriter or selling group member
engaged in passive market making is subject to a daily
 
                                       33

net purchase limitation equal to 30% of such entity's average daily trading
volume during the two full consecutive calendar months immediately preceding the
date of the filing of the registration statement under the Securities Act
pertaining to the security to be distributed.
 
     The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments the Underwriters may be required to
make in respect thereof.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
HCIA Inc.:

     We have audited the accompanying consolidated balance sheets of HCIA Inc.
and subsidiaries as of December 31, 1994 and 1995, and the related consolidated
statements of operations, changes in stockholders' equity and cash flows for
each of the years in the three-year period ended December 31, 1995. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of HCIA Inc.
and subsidiaries as of December 31, 1994 and 1995, and the results of their
operations and their cash flows for each of the years in the three-year period

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1993, 1994 AND 1995
 
(1)  BACKGROUND
 
  (a) DESCRIPTION OF BUSINESS
 
     HCIA Inc. ("HCIA" or the "Company") is a health care information content
company that develops and markets integrated clinical information systems and
products. The Company's systems and products range from standardized data bases
to highly focused Decision Support Systems that assist its customers in
evaluating the efficacy and economics of health care delivery. The Company's
customers include hospitals, integrated delivery systems, self-insured
employers, pharmaceutical companies and managed care organizations.
 
  (b) PUBLIC OFFERINGS
 
     During February 1995, the Company completed an initial public offering of
approximately 2.0 million shares of Common Stock at $14.00 per share. In August
1995, the Company completed a second public offering of approximately 2.6
million shares at $28.50 per share. The second public offering consisted of 1.5
million shares issued by the Company and approximately 1.1 million shares sold
by the Company's largest stockholder, AMBAC Inc. ("AMBAC").
 
  (c) ACQUISITIONS
 
     On April 28, 1995, the Company acquired all of the capital stock of Datis
Corporation ("Datis") for $14,250,000 in cash. Datis provides databases and
related analyses to hospitals and hospital systems. The acquisition was
accounted for using the purchase method of accounting and resulted in increases
in current assets of $1,338,000, furniture and equipment of $1,092,000, other
assets of $25,000, software of $233,000 and other intangible assets of
$16,503,000; offset by increases in current liabilities of $4,671,000 and long
term liabilities of $270,000. Substantially all of the other intangible assets
recorded in connection with this acquisition relate to goodwill. The goodwill is
being amortized over its estimated useful life of 20 years. The estimate of the
amortization period is based on the nature of the products and markets of Datis
and the historical rate of change in the products and markets. Funding for the
acquisition was provided from the proceeds of the Company's initial public
offering.
 
     During November 1995, the Company acquired an additional 36% interest in
CHKS Limited ("CHKS"). As a result of this acquisition, CHKS became a
wholly-owned subsidiary of the Company. The Company issued notes payable to the
former shareholders in the amount of $2,795,000. The purchase agreement also
provides for an additional payment to the former shareholders in the event that
certain operational performance targets are met by CHKS during 1996. This
acquisition was accounted for using the purchase method of accounting and
resulted in additional goodwill of $2,709,000. The goodwill is being amortized
over its estimated useful life of 15 years. The estimate of the amortization
period is based on the nature of the products and markets of CHKS and the
historical rate of change in the products and markets.
 
     On December 15, 1995, the Company acquired the assets constituting the
CHAMP unit of William M. Mercer, Incorporated for $17,500,000 in cash. The CHAMP
unit provides data base and analytical reporting services to large employers to
assist them in the management of their health care costs. The acquisition was
accounted for using the purchase method of accounting and resulted in an
increase in software of $859,000 and other intangible assets of $4,489,000. The
other intangible assets consist of trade names of $1,266,000, assembled
workforce of $1,102,000, customer base of $595,000 and goodwill of $1,526,000.
These assets are being amortized on a straight-line basis over 12 years. The
lives of these assets were determined by an independent appraiser based on,
among other things, employee turnover, historical customer retention rates and
the historical rate of change in the products and markets. At the date of the
acquisition, the Company recorded a non-recurring charge of $12,152,000 relating
to in-process research and development costs which were acquired in this
acquisition.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
These costs related to the development of a client server based system to
process and deliver health care data and analysis tools to CHAMP customers. The
amount of the non-recurring charge was equal to the estimated current fair
value, based on the risk adjusted cash flows (at a discount rate of 20%, which
included cost of capital of 18% and an incremental risk premium of 2%), of
specifically identified technologies for which technological feasibility had not
yet been established pursuant to Statement of Financial Accounting Standards No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased or
Otherwise Marketed," and for which future alternative uses did not exist.
Consideration of technological feasibility for purposes of this calculation was
done on a basis consistent with that normally utilized by the Company (See Note
2(d)). This charge is recorded as an operating expense on the accompanying
consolidated statement of operations for the year ended December 31, 1995.
Funding for this acquisition was provided from the proceeds of the Company's
public offerings.
 
     During 1995, the Company also acquired certain assets and assumed certain
liabilities of John Froehlich Associates, MetriCor Inc. and MetaGenerics. The
aggregate purchase price for these acquisitions was $1,677,000, consisting of
cash of $1,166,000 and notes payable of $511,000. These acquisitions were
accounted for using the purchase method of accounting and resulted in increases
in furniture and equipment of $75,000, increases in other intangible assets of
$1,938,000 and increases in current liabilities of $336,000. The other
intangible assets consist of goodwill which is being amortized on a
straight-line basis over estimated useful lives of 10 to 15 years. The estimate
of each amortization period is based on the nature of the products and markets
of the acquired entities and the historical rate of change in the products and
markets. Funding for these acquisitions was provided from the proceeds of the
Company's public offerings.
 
     Unaudited pro forma combined results of the operations of the Company for
the years ended December 31, 1995 and 1994 are presented below and have been
prepared assuming that the acquisitions discussed above had been made as of
January 1, 1994.

</TABLE>

     The pro forma results include the historical accounts of the Company and
the acquired entities adjusted to reflect the effects of the depreciation and
amortization of the acquired identifiable tangible and intangible assets based
on the new cost basis of the assets acquired, additional interest expense
related to notes payable issued in connection with certain acquisitions, the
reversal of the non-recurring write-off of acquired in-process research and
development costs recorded in connection with the CHAMP acquisition and the
related income tax effects. The pro forma results are not necessarily indicative
of actual results which might have occurred had the operations and management of
the Company and the acquired entities been combined in 1994 and 1995.
 
  (d) DIVESTITURE
 
     Effective January 1, 1994, the Company sold certain of its software product
lines at their approximate book value to a company formed by a group of the
Company's former employees. These product lines generated revenues of
approximately $3.0 million during the year ended December 31, 1993. In
connection with the sale, the Company received a note in the amount of
$1,659,000 and also purchased a 49% equity interest in the new entity for
$120,000. During 1995, the Company received payment in full on the balance
outstanding on the note and sold the equity interest back to the entity for
$139,000, representing the original investment of $120,000 plus interest for the
period the equity interest was held.

     The portfolio is carried at fair value in accordance with Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." All securities mature within one year. Gross
unrealized gains and losses were $44,000 and $0, respectively, and are included
as a separate component of stockholders' equity. Realized gains and losses are
recorded using the specific identification basis to determine costs. During
1995, proceeds from sales of the securities totalled $46,677,000, gross realized
gains totalled $2,000 and gross realized losses totalled $0.
 
  (c) FURNITURE AND EQUIPMENT
 
     Furniture and equipment are stated at cost. Included in furniture and
equipment are computer hardware, furniture and fixtures and leasehold
improvements. These costs are being depreciated on the straight-line method over
their estimated useful lives of three to five years.
 
  (d) COMPUTER SOFTWARE COSTS
 
     Computer software costs include the cost of internally developed software
and the fair market value assigned to computer software obtained in purchase
transactions. Costs for internally developed software are capitalized in
accordance with Statement of Financial Accounting Standards No. 86, "Accounting
for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed."
These costs relate primarily to the building of production systems and extending
existing applications to new markets or platforms using existing technologies
and programming methods. The Company capitalizes only those costs incurred after
a detailed program design or, in the absence of such, a working prototype has
been developed. The Company generally develops its applications in connection
with customer contracts and includes the related costs as a component of
operating expenses in the period incurred. The Company capitalized or purchased
a total of $2,236,000, $2,603,000 and $7,260,000 of computer software costs in
1993, 1994 and 1995, respectively, including $1,109,000 in 1995 related to
business acquisitions.
 
     Capitalized costs are amortized, beginning with market availability, over
the economic useful life of the product. Typically, this life is five years. The
annual amortization expense is the greater of the amount computed using (a) the
ratio that current gross revenues for a product bears to the total of current
and anticipated future gross revenues for that product or (b) the straight-line
method over the remaining estimated economic life of the product including the
period being reported. Amortization expense for computer software was
$1,540,000,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
$1,456,000 and $2,048,000 during 1993, 1994 and 1995, respectively. Accumulated
amortization for computer software was $4,462,000 and $6,510,000 at December 31,
1994 and 1995, respectively.
 
     The Company evaluates, on a quarterly basis, the recoverability of
capitalized software costs on the basis of whether such costs are fully
recoverable from projected undiscounted cash flows of individual system and
product lines.
 
  (e) REVENUE RECOGNITION
 
     Revenue from license fees for access to the Company's data bases is
recognized when access to the data base is made available to the customer.
Revenue from custom system or data base development and implementation contracts
is recognized on a percentage of completion basis using the cost to cost method.
On a quarterly basis, the Company assesses whether the current estimate of total
contract costs for each of these contracts indicates a loss is expected and
accrues any such losses on the entire contract in that quarter. Where the
Company has contracted to provide both access to a Company data base and
development of a custom data base, the contract value is segmented into its
discrete elements according to their relative values, and revenue is recognized
separately on each element in accordance with the above.
 
     Revenue from group data contracts, which obligate the Company to process
data, produce reports and update data bases on periodic intervals, is recognized
as the contracted obligations are fulfilled.
 
     Revenue from licensing of software products is recognized upon shipment,
provided that no vendor obligations remain outstanding. While the Company has no
significant post-contract support (PCS) obligations, any revenue related to
insignificant PCS obligations on software licenses is deferred and recognized
over the contract term. The Company determines the component of revenue
applicable to PCS obligations based upon its experience in fulfilling such
obligations.
 
     Revenue on all other products is recognized when the product is shipped.
 
     During 1993 and 1994, one customer accounted for 12% of the Company's
revenue. At December 31, 1994, receivables from that customer represented 12% of
the Company's trade accounts receivable. Consistent with Company policy, no
collateral or other security was held with respect to such trade accounts
receivable. During 1995, no single customer accounted for 10% or more of the
Company's revenue or trade accounts receivable.
 
  (f) FOREIGN CURRENCY TRANSLATION
 
     The assets and liabilities of CHKS are translated at year-end exchange
rates, while revenue and expenses are translated at rates prevailing during the
period. Accordingly, translation adjustments that arise due to fluctuations in
exchange rates are excluded from operations and are reported as a separate
component of stockholders' equity.
 
  (g) INCOME TAXES
 
     Prior to the completion of the Company's initial public offering in
February 1995, the Company was party to a federal tax-sharing agreement with
AMBAC and was included in AMBAC's consolidated federal income tax return. The
tax-sharing agreement provided for the determination of tax expense or benefit
based on the contribution of the Company to AMBAC's tax liability, computed
substantially as if the Company filed a separate income tax return. The tax
liability due AMBAC was settled quarterly, with a final settlement taking place
after the filing of the consolidated federal tax return. Commencing February 22,
1995, the Company is no longer included on a consolidated basis for tax purposes
with AMBAC and is responsible for filing its own federal income tax return.
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No. 109"),
and the cumulative effect of this change as of that date is reported in the
consolidated statement of operations for 1993.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Under SFAS No. 109, the Company uses the asset and liability method to
account for deferred income taxes. Under this method, deferred income taxes are
recognized for temporary differences between the financial reporting bases of
assets and liabilities and their respective tax bases and for operating loss and
tax credit carryforwards based on enacted rates expected to be in effect when
such amounts are realized or settled. The effects of changes in tax laws or
rates on deferred tax assets and liabilities are recognized in the period that
includes the enactment date.
 
  (h) EARNINGS PER SHARE
 
     Earnings per share has been calculated based upon the weighted average
number of shares outstanding and using the treasury stock method for outstanding
stock options. The number of shares used in this calculation has been adjusted
to reflect a one-for-three reverse stock split and the conversion of Class A and
Class B common stock into a single class of common stock (see note 10). For
1994, the fair market value per share for the purpose of the calculation of the
weighted average shares outstanding was assumed to be $11.00, which was the
mid-point of the initial public offering price range.
 
  (i) USE OF ESTIMATES
 
     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these financial statements in
conformity with generally accepted accounting principles. Actual results could
differ from those estimates.
 
  (j) RECLASSIFICATIONS
 
     Certain amounts for 1993 and 1994 have been reclassified to conform to the
presentation for 1995.

</TABLE>
 
     Data bases consist of the fair market value of various data bases acquired
through acquisitions, the cost of acquiring data and internal development costs
(direct labor and related overhead) incurred in standardizing data for use in
internally developed data bases. These assets are being amortized on a
straight-line basis over their estimated useful lives of five years.
Amortization expense for data bases was approximately $849,000, $839,000 and
$962,000 during 1993, 1994 and 1995, respectively.
 
     During 1992, the Company acquired an exclusive license to access and sell
the data bases and certain other assets of the Commission on Professional and
Hospital Activities ("CPHA"). This license was recorded at its estimated fair
value of $8,073,000 at the date of acquisition and is being amortized on a
straight-line basis over 17 years. The amortization period was determined to be
the estimated economic life cycle of the licensed properties, as corroborated by
an independent appraisal, and reflected the remainder of the existing term of
the license at the date of acquisition plus one renewal term provided under the
terms of the agreement.
 
     Under the terms of the license, the Company paid royalties to CPHA based on
revenues earned utilizing the licensed assets. Subsequent to the acquisition,
the Company and CPHA entered into a new license agreement. Under the terms of
the new agreement, the Company paid $5,958,000 to CPHA in lieu of future royalty
obligations. The payment is recorded as prepaid CPHA royalties and is being
amortized on a straight-line basis over 17 years, consistent with the estimated
economic life of the licensed properties.
 
     Goodwill represents the excess of the purchase price over the fair value of
net assets acquired. Goodwill is being amortized on a straight-line basis over
10 to 20 years. Such amortization periods are estimated based on the nature of
the products and markets of the acquired companies and the historical rates of
changes in these products and market areas.
 
     Other intangibles consist of noncompetition agreements and identifiable
intangible assets obtained through acquisitions. The noncompetition agreements
are amortized over their 1 to 2 year terms. Certain of the noncompetition
agreements are with the original stockholders of the acquired company who are
still employed by the Company or AMBAC as of December 31, 1995. Amortization of
these agreements, which are valued at $684,000, will commence when the
stockholders are no longer employees of AMBAC or the Company. The acquired
identifiable intangible assets consist of trade names, assembled workforce,
customer base and methodologies. The trade names, assembled workforce and
customer base were obtained through the CHAMP acquisition, and are being
amortized over 12 years. The lives of these assets were determined by an
independent appraiser based on factors such as going concern value, employee
turnover and historical customer retention rates. The methodologies are being
amortized over their estimated useful lives of 5 years.

sharing plan qualified under Section 401(a) of the Internal Revenue Code. All
employees of the Company who have completed one year of service are eligible to

(11)  RELATED PARTY TRANSACTIONS
 
     In January 1993 and 1994, the Company executed credit agreements with
AMBAC. The credit agreement entered into in January 1994 replaced the prior
agreement and extended a revolving line of credit of $2.5 million (subject to
certain borrowing base limitations) at a rate based upon the prime rate of
Citibank, N.A. in New York, New York. The Company was also required to pay AMBAC
a commitment fee on the average daily unused portion of the line of credit at a
rate of 0.25% per annum. The Company utilized approximately $1.9 million of the
proceeds from its initial public offering to repay the outstanding borrowings
under the credit agreement. The credit agreement was terminated in May 1995.
 
     Until August 1995, the Company maintained its business insurance, including
property, general liability, automobile, workers' compensation and fidelity and
fiduciary coverage (including officers' and directors' liability insurance)
through AMBAC, which purchased insurance coverage for the Company. The Company
was charged its pro rata share of premiums. The amounts of premiums paid to
AMBAC by the Company were $90,000, $72,000 and $89,000 for policy years 1993,
1994 and 1995, respectively.
 
     AIC purchases information services from the Company. Such purchases totaled
$262,000, $288,000 and $250,000 during 1993, 1994 and 1995, respectively.
 
(12)  DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amount of cash and cash equivalents, trade accounts
receivable, other current assets, accounts payable, accrued expenses and capital
lease obligations approximates fair value because of the short-term maturity of
these instruments. The fair value of short-term investments is estimated based
on quoted market prices for these or similar investments. The Company has notes
receivable from and notes payable to individuals relating to certain of its
business acquisitions. It is not practicable to estimate the fair value of these
notes since they are not traded, no quoted values are readily available for
similar financial instruments and the Company believes it is not cost-effective
to have valuations performed. However, management believes that there has been
no permanent impairment in the value of such notes.

"Accounting for Stock-based Compensation" ("SFAS No. 123"), was issued. This
statement requires the fair value of stock options and other stock-based
compensation issued to employees to either be included as compensation expense
in the income statement, or the pro forma effect on net income and earnings per
share of such compensation expense to be disclosed in the notes to the Company's
consolidated financial statements commencing with the Company's 1996 fiscal
year. The Company expects to adopt SFAS No. 123 on a disclosure basis only. As
such, implementation of SFAS No. 123 is not expected to impact the Company's
consolidated financial statements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In March 1995, Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of " ("SFAS No. 121"), was issued. This Statement establishes
accounting standards for the impairment of long-lived assets, certain
identifiable intangibles, and goodwill related to those assets to be held and
used for long-lived assets and certain identifiable intangibles which are to be
disposed. Implementation of SFAS No. 121 is not expected to have a material
impact on the Company's consolidated financial statements.
 
(14)  SUBSEQUENT EVENTS (UNAUDITED)
 
     In May 1996, the Company acquired all of the outstanding capital stock of
Response Healthcare Information Management, Inc. ("Response") for approximately
$6,200,000 in cash. Response specializes in capturing and analyzing
point-of-care, patient-centered data relating to disease-specific outcomes
measurement, member/patient satisfaction and functional status, as well as the
development of Internet applications. Response's primary customers include
managed care organizations and pharmaceutical companies. At the date of the
acquisition, the Company recorded a non-recurring charge of $4,372,000 relating
to acquired in-process research and development costs.
 
   
     On August 9, 1996, the Company acquired LBA Health Care Management, Inc.
("LBA") through the acquisition of all of the capital stock of its parent
company, HealthVISION, Inc., for approximately $130,000,000, $100,000,000 of
which is payable in cash and $30,000,000 of which is payable by the delivery of
492,961 shares of common stock of the Company. The Company utilized a
$100,000,000 bank credit facility to fund the cash portion of the purchase
price, which the Company intends to repay with the net proceeds of an offering
of its common stock soon after the date of acquisition. LBA is a provider of
health care information products and services that combine data collection,
benchmarking and decision support tools to identify and quantify cost reduction
and quality improvement opportunities in clinical settings.

THE BOARD OF DIRECTORS AND STOCKHOLDERS
LBA HEALTH CARE MANAGEMENT, INC.

     We have audited the accompanying combined balance sheet of LBA Health Care
Management, Inc. and Healthcare Data Source, Inc. (collectively, the
"Predecessor Business") as of December 31, 1994, the combined statements of
operations and retained earnings, and cash flows for the Predecessor Business
for each of the years ended December 31, 1993 and 1994 and for the period from
January 1, 1995 through September 27, 1995, the balance sheet of LBA Health Care
Management, Inc. as of December 31, 1995, and the statements of operations and
retained earnings, and cash flows of LBA Health Care Management, Inc. for the
period from September 28, 1995 through December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of LBA Health Care
Management, Inc. and Healthcare Data Source, Inc. at December 31, 1994 and 1995,
the combined results of their operations and retained earnings, and their cash
flows for each of the years ended December 31, 1993, 1994 and for the period
from January 1, 1995 through September 27, 1995, and the financial position of
LBA Health Care Management, Inc. at December 31, 1995, and the results of its
operations and retained earnings, and its cash flows for the period from
September 28, 1995 through December 31, 1995 in conformity with generally
accepted accounting principles.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  REVENUE RECOGNITION
 
     Revenue is recognized ratably over the estimated time to complete a
contract which is six to twelve months in duration.
 
     The Company has offered Value Enhancement systems to health care providers
throughout the United States. As part of the Value Enhancement Programs, the
Company has guaranteed that each customer will achieve cost savings. In the
event such cost savings are not achieved, the Company may be subject to claims
related to such guarantees. The Company or its predecessor did not incur any
such claims during the periods ended December 31, 1993, 1994 and 1995. No
reserves are maintained for any potential future claims.
 
  ACCOUNTS RECEIVABLE
 
     Receivable balances represent amounts due primarily from hospitals in the
United States for consulting work performed. The Company performs ongoing credit
evaluations of these companies and generally does not require collateral.

  UNBILLED RECEIVABLES
 
     Unbilled receivables represent recoverable costs and accrued profit related
to contracts on which revenue has been recognized, but billings have not been
presented to the customer.
 
  INTANGIBLES
 
     Intangibles reflect the allocation of excess purchase price resulting from
the acquisition of the Predecessor Business. Amortization is based upon the
periods of expected economic benefit which are as follows: goodwill -- 20 years,
covenants-not-to-compete -- 3 years, value enhancements -- 2.5 years,
backlog -- 1 year, and assembled workforce -- 3 years.
 
     Acquired technology which is in process, has not reached technological
feasibility, and has no alternative future use is written-off in the period in
which it is acquired. The write-off of in-process technology was $1,580,000 for
the period September 28, 1995 through December 31, 1995.
 
     Intangibles consist of the following:

     Amortization has been expensed in the accompanying statements of operations
as cost of revenue of $1,911,033 and general and administrative of $2,844,839.
 
     The Company performs evaluations as of each balance sheet date assessing
the recoverability and amortization of intangibles by determining whether the
intangibles can be recovered through the estimated undiscounted cash flows of
the businesses acquired over the remaining amortization period. The Company
considers external factors relating to each acquired business, including
technological advances, competition, regulatory developments and trends of the
businesses and other pertinent factors in making its assessment. The Company
does not believe there are currently any factors that would require an
adjustment to the carrying value of its intangibles or their remaining lives as
of December 31, 1995.
 
  BUILDING, EQUIPMENT AND FURNITURE
 
     Building, equipment and furniture are recorded at cost. Depreciation is
computed using the straight-line method over the estimated useful lives of the
assets which are as follows:

  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 amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  RECLASSIFICATIONS
 
     Certain prior year balances have been reclassified to conform to the 1995
presentation. Additionally, retained earnings at January 1, 1993 was restated to
properly account for a prior period adjustment in the amount of $518,940.
 
3. INCOME TAXES
 
     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 ("Statement 109"), "Accounting for Income
Taxes". Under Statement 109, the liability method is used to account for income
taxes. Under this method, deferred taxes and liabilities are determined based on
differences between the financial reporting and tax bases of assets and
liabilities and are measured using the enacted tax rates and laws that will be
in effect when the differences are expected to reverse.
 
     The Predecessor Business elected to be classified as an S corporation under
Section 1362 of the Internal Revenue Code for federal and state income tax
purposes. Accordingly, federal income taxes on any earnings were payable by the
Predecessor Business' stockholders and not the S corporations themselves; state
income taxes were immaterial and were payable by both the Predecessor Business
and its stockholders. The provision for income taxes for the years ended
December 31, 1993 and 1994 and for the period from January 1, 1995 through
September 27, 1995 were immaterial and are not separately disclosed in the
accompanying financial statements.
 
     Significant components of the Company's deferred tax liabilities and assets
as of December 31, 1995 are as follows:

LEGAL PROCEEDINGS
 
     The Company is currently a defendant to a civil complaint filed April 26,
1996, in the United States District Court of Colorado, by a former employee. The
complaint alleges that the former employee was unlawfully discharged from the
the Company. The Company believes that the suit is without merit and intends to
defend its position vigorously. While the ultimate outcome of this lawsuit can
not be determined at this time, management does not believe that this matter
will have a material adverse effect on the financial position, cash flows or
results of operations of the Company.
 
   
     In connection with the purchase by HealthVISION, Inc. in September 1995 of
the assets of the predecessor of LBA, a current minority stockholder of
HealthVISION, Inc. threatened suit. The Company and certain other parties
executed an agreement on July 30, 1996, which, upon consummation of the
Company's contemplated transaction with HCIA Inc., will resolve any
disagreements between the parties as of that date and provides for a release of
all claims.

includes the impact of using the treasury stock method for outstanding stock
options as such stock options are dilutive to earnings per share. In the columns
reflecting a loss for the period, the impact of the outstanding stock options is
not included in the calculation of weighted average shares outstanding as such
options are antidilutive.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 2-418 of the Maryland General Corporation Law (the "MGCL") provides
that the Registrant may indemnify any director who was, is or is threatened to
be made a named defendant or respondent to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative by reason of the fact that he is or was a director of the
Registrant, or while a director, is or was serving at the request of the
Registrant as a director, officer, partner, trustee, employee or agent of
another foreign or domestic corporation, partnership, joint venture, trust,
other enterprise or employee benefit plan, against reasonable expenses
(including attorneys' fees), judgments, penalties, fines and settlements,
actually incurred by the director in connection with such action, suit or
proceeding, unless it is established that: (i) the act or omission of the
director was material to the matter giving rise to such action, suit or
proceeding, and was committed in bad faith or was the result of active and
deliberate dishonesty; (ii) the director actually received an improper personal
benefit in money, property or services; or (iii) in the case of any criminal
proceeding, the director had reasonable cause to believe that the act or
omission was unlawful. If the action, suit or proceeding was one by or in the
right of the Registrant, no indemnification shall be made with respect to any
action, suit or proceeding in which the director shall have been adjudged to be
liable to the Registrant. A director also may not be indemnified with respect to
any action, suit or proceeding charging improper personal benefit to the
director, whether or not involving action in the director's official capacity,
in which the director is adjudged to be liable on the basis that a personal
benefit was improperly received. Unless limited by the Registrant's Charter: (i)
a court of appropriate jurisdiction, upon application of a director, may order
such indemnification as the court shall deem proper if it determines that the
director is fairly and reasonably entitled to indemnification in view of all of
the relevant circumstances, regardless of whether the director has met the
standards of conduct required by Section 2-418; and (ii) the Registrant shall
indemnify a director if such director is successful on the merits or otherwise
in defense of any action, suit or proceeding referred to above. However, with
respect to any action, suit or proceeding by or in the right of the Registrant
or in which the director was adjudged to be liable on the basis that a personal
benefit was improperly received, the Registrant may only indemnify the director
for any expenses (including, attorneys' fees) incurred in connection with such
action, suit or proceeding.

     Section 2-418 of the MGCL further provides that unless limited by the
Registrant's Charter, the Registrant: (i) shall (a) indemnify an officer of the
Registrant if such officer is successful on the merits or otherwise in defense
of any action, suit or proceeding referred to above, and (b) indemnify an
officer of the Registrant if a court of appropriate jurisdiction, upon
application of an officer, shall order indemnification; (ii) may indemnify and
advance expenses to an officer, employee or agent of the Registrant to the same
extent that it may indemnify

                                      II-1

<PAGE>
directors; and (iii) may indemnify and advance expenses to an officer, employee
or agent who is not a director to such further extent, consistent with law, as
may be provided by the Charter, Bylaws, general or specific action of the
Registrant's Board of Directors or contract.

     The Registrant's Bylaws provide that the Registrant shall indemnify: (i)
any individual who is a present or former director or officer of the Registrant;
or (ii) any individual who serves or has served in another corporation,
partnership, joint venture, trust, employee benefit plan or any other enterprise
as a director or officer, or as a partner or trustee of such partnership or
employee benefit plan, at the request of the Registrant and who by reason of
service in that capacity was, is or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, to the full extent permitted under
the MGCL. The Registrant may, with the approval of its Board of Directors,
provide such indemnification for a person who formerly served a predecessor of
the Registrant in any of the capacities described in (i) or (ii) above and for
any employee or agent of the Registrant or a predecessor of the Registrant.

     The Registrant's Bylaws also provide that the reasonable expenses incurred
by a director or officer who is or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, shall be paid or reimbursed by the
Registrant in advance of the final disposition of the proceeding upon receipt by
the Registrant of: (i) a written affirmation by the party seeking
indemnification that he has a good faith belief that the standard of conduct
necessary for indemnification by the Registrant has been met; and (ii) a written
undertaking by or on behalf of the party seeking indemnification to repay the
amount if it shall ultimately be determined that such standard of conduct has
not been met.

     The Registrant's Charter provides that, to the fullest extent permitted by
Maryland statutory or decisional law, as amended or interpreted, no director or
officer of the Registrant shall be personally liable to the Registrant or its
stockholders for monetary damages. The Registrant's Charter also provides that
except as the Bylaws of the Registrant may otherwise provide, no indemnification
shall be provided for any director or officer or for any employee or agent of
the Registrant or any predecessor of the Registrant or any other entity.

     The provisions in the Charter and Bylaws do not eliminate the duty of care.
In appropriate circumstances, equitable remedies such as injunctive or other
forms of non-monetary relief remain available under Maryland law. In addition,
each director will continue to be subject to liability for breach of the
director's duty of loyalty to the Registrant or its stockholders, for acts or
omissions not in good faith or involving intentional misconduct or knowing
violations of law, for actions leading to improper personal benefit to the
director and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under the MGCL. These provisions also do not
affect a director's or officer's responsibilities under any other law, such as
the federal or state securities laws or state or federal environmental laws.

     The Underwriting Agreement (a form of which is filed as Exhibit 1.1 hereto)
will provide that the Underwriters shall indemnify and hold harmless the Selling
Stockholders, the Registrant and each director, officer or controlling person of
the Registrant from and against any liability caused by any statement or
omission in the Registration Statement or Prospectus based upon certain
information furnished to the Registrant by the Underwriters for use in the
preparation thereof.

ITEM 17.  UNDERTAKINGS.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

                                      II-4

<PAGE>
     The undersigned Registrant hereby undertakes that:

          1. For purposes of determining any liability under the Securities Act,
     the information omitted from the form of prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.

          2. For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new Registration Statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

of Baltimore, State of Maryland, on August 13, 1996.

Ladies and Gentlemen:

         HCIA Inc.,  a Maryland  corporation  (the  "Company"),  and the persons
listed  in  Schedule  B  hereto  (the  "Selling  Stockholders"),  confirm  their
respective  agreements with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated ("Merrill Lynch"), Alex. Brown & Sons Incorporated, Hambrecht
& Quist  LLC,  Montgomery  Securities  and  Robertson,  Stephens  & Company  LLC
(collectively, the "Underwriters", which term shall also include any underwriter
substituted  as  hereinafter  provided in Section 10 hereof) with respect to the
sale by the Company  and the  Selling  Stockholders,  acting  severally  and not
jointly, and the purchase by the Underwriters, acting severally and not jointly,
of the respective  numbers of shares of Common Stock,  par value $.01 per share,
of the Company ("Common Stock"), set forth in Schedules A and B hereto, and with
respect  to the grant by the  Company  to the  Underwriters,  severally  and not
jointly,  of the option  described in Section 2(b) hereof to purchase all or any
part of 332,505 additional shares of Common Stock to cover  over-allotments,  if

                                       1

<PAGE>



shares of  Common  Stock  (the  "Initial  Securities")  to be  purchased  by the
Underwriters  and all or any part of the 332,505  shares of Common Stock subject
to the option  described in Section 2(b) hereof (the  "Option  Securities")  are
hereinafter called, collectively, the "Securities".

         The  Company  and  the  Selling   Stockholders   understand   that  the
Underwriters  propose to make a public offering of the Securities as soon as the
Underwriters   deem  advisable  after  this  Agreement  has  been  executed  and
delivered.

         The Company has filed with the Securities and Exchange  Commission (the
"Commission") a registration  statement on Form S-3 (No. 333-08639) covering the
registration of the Securities under the Securities Act of 1933, as amended (the
"1933 Act"),  including  the related  preliminary  prospectus  or  prospectuses.
Promptly after execution and delivery of this Agreement, the Company will either
(i) prepare and file a prospectus in accordance with the provisions of Rule 430A
("Rule 430A") of the rules and regulations of the Commission  under the 1933 Act
(the "1933 Act  Regulations")  and paragraph (b) of Rule 424 ("Rule  424(b)") of
the 1933 Act  Regulations  or (ii) if the  Company has elected to rely upon Rule
434 ("Rule 434") of the 1933 Act  Regulations,  prepare and file a term sheet (a
"Term Sheet") in accordance with the provisions of Rule 434 and Rule 424(b). The
information  included in such  prospectus or in such Term Sheet, as the case may
be,  that was omitted  from such  registration  statement  at the time it became
effective  but that is deemed to be part of such  registration  statement at the
time it became  effective (i) pursuant to paragraph (b) of Rule 430A is referred
to as "Rule 430A  Information"  or (ii) pursuant to paragraph (d) of Rule 434 is
referred  to as  "Rule  434  Information."  Each  prospectus  used  before  such
registration  statement became  effective,  and any prospectus that omitted,  as
applicable, the Rule 430A Information or the Rule 434 Information, that was used
after  such  effectiveness  and  prior to the  execution  and  delivery  of this
Agreement,  is  herein  called a  "preliminary  prospectus."  Such  registration
statement,  including the exhibits thereto,  schedules thereto,  if any, and the
documents  incorporated  by  reference  therein  pursuant to Item 12 of Form S-3
under the 1933 Act, at the time it became  effective and including the Rule 430A
Information and the Rule 434  Information,  as applicable,  is herein called the
"Registration  Statement."  Any  registration  statement  filed  by the  Company
pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the
"Rule  462(b)   Registration   Statement,"   and  after  such  filing  the  term
"Registration  Statement" shall include the Rule 462(b) Registration  Statement.
The final prospectus,  including the documents incorporated by reference therein
pursuant to Item 12 of Form S-3 under the 1933 Act, in the form first  furnished
to the Underwriters for use in connection with the offering of the Securities is
herein called the  "Prospectus." If Rule 434 is relied on, the term "Prospectus"
shall refer to the preliminary  prospectus dated July 26, 1996 together with the
Term Sheet and all  references in this  Agreement to the date of the  Prospectus
shall mean the date of the Term  Sheet.  For  purposes  of this  Agreement,  all
references  to the  Registration  Statement,  any  preliminary  prospectus,  the
Prospectus  or any  Term  Sheet or any  amendment  or  supplement  to any of the
foregoing shall be deemed to include the copy filed with the Commission pursuant
to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

         All references in this Agreement to financial  statements and schedules
and other  information  which is  "contained,"  "included"  or  "stated"  in the
Registration  Statement,  any preliminary prospectus or the Prospectus (or other
references of like import) shall be deemed to

                                       2

<PAGE>



mean  and  include  all  such  financial  statements  and  schedules  and  other
information  which is incorporated by reference in the  Registration  Statement,
any  preliminary  prospectus  or the  Prospectus,  as the case  may be;  and all
references in this Agreement to amendments or  supplements  to the  Registration
Statement,  any preliminary prospectus or the Prospectus shall be deemed to mean
and include the filing of any document under the Securities Exchange Act of 1934
(the  "1934  Act")  which  is  incorporated  by  reference  in the  Registration
Statement, such preliminary prospectus or the Prospectus, as the case may be.


         SECTION 1.        Representations and Warranties.

         (a)  Representations  and  Warranties  by  the  Company.   The  Company
represents  and warrants to each  Underwriter  as of the date hereof,  as of the
Closing Time referred to in Section 2(c) hereof, and as of each Date of Delivery
(if any) referred to in Section 2(b) hereof,  and agrees with each  Underwriter,
as follows:

                  (i) Compliance  with  Registration  Requirements.  The Company
         meets the  requirements for use of Form S-3 under the 1933 Act. Each of
         the Registration  Statement and any Rule 462(b) Registration  Statement
         has become  effective  under the 1933 Act and no stop order  suspending
         the  effectiveness  of the  Registration  Statement  or any Rule 462(b)
         Registration  Statement  has  been  issued  under  the  1933 Act and no
         proceedings for that purpose have been instituted or are pending or, to
         the knowledge of the Company,  are contemplated by the Commission,  and
         any request on the part of the Commission  for  additional  information
         has been complied with.

                  At the respective times the Registration  Statement,  any Rule
         462(b) Registration Statement and any post-effective amendments thereto
         became effective and at the Closing Time (and, if any Option Securities
         are purchased,  at the Date of Delivery),  the Registration  Statement,
         the  Rule  462(b)   Registration   Statement  and  any  amendments  and
         supplements  thereto complied and will comply in all material  respects
         with the  requirements of the 1933 Act and the 1933 Act Regulations and
         did not and will not contain an untrue  statement of a material fact or
         omit to  state  a  material  fact  required  to be  stated  therein  or
         necessary to make the statements  therein not  misleading.  Neither the
         Prospectus nor any amendments or supplements  thereto,  at the time the
         Prospectus or any such  amendment or  supplement  was issued and at the
         Closing Time (and, if any Option Securities are purchased,  at the Date
         of  Delivery),  included  or will  include  an  untrue  statement  of a
         material  fact or  omitted  or  will  omit to  state  a  material  fact
         necessary in order to make the statements  therein, in the light of the
         circumstances  under which they were made, not misleading.  If Rule 434
         is  used,  the  Company  will  comply  with  the  prospectus   delivery
         requirements  of Rule 434. The  representations  and warranties in this
         subsection  shall  not apply to  statements  in or  omissions  from the
         Registration Statement (or any amendment thereto) or Prospectus (or any
         amendment  or  supplement   thereto)  made  in  reliance  upon  and  in
         conformity with (x) information  furnished to the Company in writing by
         any  Underwriter  through  Merrill  Lynch  expressly  for  use  in  the
         Registration Statement (or any amendment thereto) or Prospectus (or any
         amendment or supplement  thereto) and (y) information  furnished to the
         Company in writing by or on behalf of any

                                       3

<PAGE>



         Selling Stockholder expressly for use in the Registration Statement (or
         any amendment  thereto) or  Prospectus  (or any amendment or supplement
         thereto).

                  Each  preliminary  prospectus and the prospectus filed as part
         of the  Registration  Statement as  originally  filed or as part of any
         amendment  thereto,  or filed  pursuant to Rule 424 under the 1933 Act,
         complied  when so  filed  in all  material  respects  with the 1933 Act
         Regulations  and  each   preliminary   prospectus  and  the  Prospectus
         delivered to the  Underwriters for use in connection with this offering
         was   identical  in  all  material   respects  to  the   electronically
         transmitted copies thereof filed with the Commission pursuant to EDGAR,
         except to the extent permitted by Regulation S-T.

                  (ii)  Incorporated  Documents.  The documents  incorporated or
         deemed to be  incorporated by reference in the  Registration  Statement
         and the Prospectus, when they became effective or at the time they were
         or hereafter are filed with the Commission, complied and will comply in
         all material  respects  with the  requirements  of the 1934 Act and the
         rules and  regulations  of the  Commission  thereunder  (the  "1934 Act
         Regulations"),  as  applicable,  and, when read together with the other
         information in the Prospectus,  at the time the Registration  Statement
         became  effective,  at the time the  Prospectus  was  issued and at the
         Closing Time (and, if any Option Securities are purchased,  at the Date
         of  Delivery),  did not and will not contain an untrue  statement  of a
         material  fact or omit to state a material  fact  required to be stated
         therein or necessary to make the statements therein not misleading.

                  (iii)  Independent Accountants.  The accountants who certified
         the financial statements and supporting schedules  of the  Company  and
         its subsidiaries, of Datis Corporation ("Datis"),  of  the  William  M.
         Mercer,  Incorporated  National  Health  Analysis  Unit  ("CHAMP"),  of

         therein and have been compiled on a basis consistent with that of the
         audited  financial  statements of the Company and its  subsidiaries

         respective  dates as of which  information is given in the Registration
         Statement and the Prospectus,  except as otherwise stated therein,  (A)
         there has been no material  adverse change in the condition,  financial
         or  otherwise,  or  in  the  earnings,  business  affairs  or  business
         prospects  of  the  Company  and  its  subsidiaries  considered  as one
         enterprise,  whether or not arising in the ordinary  course of business
         (a  "Material  Adverse  Effect"),  (B) there have been no  transactions
         entered  into by the  Company  or any of its  subsidiaries,  other than
         those in the  ordinary  course of  business,  which are  material  with
         respect  to  the  Company  and  its  subsidiaries   considered  as  one
         enterprise,  and (C) there has been no dividend or  distribution of any
         kind declared,  paid or made by the Company on any class of its capital
         stock.  The Company and its  subsidiaries  have no material  contingent
         liabilities or obligations  which are not disclosed in the Registration
         Statement.

                  (vi) Good  Standing of the Company.  The Company has been duly
         organized  and is validly  existing as a  corporation  in good standing
         under the laws of the State of  Maryland  and has  corporate  power and
         authority to own,  lease and operate its  properties and to conduct its
         business as described in the  Prospectus  and to enter into and perform
         its obligations under this Agreement; and the Company is duly qualified

         corporation to transact  business and is in good standing in each other
         jurisdiction in which such qualification is required, whether by reason
         of the  ownership  or leasing of property  or the conduct of  business,
         except where the failure so to qualify or to be in good standing  would
         not result in a Material Adverse Effect.

                  (vii) Good Standing of  Subsidiaries.  Each  subsidiary of the
         Company  listed  on  Schedule  D  hereto  (each  a  "Subsidiary"   and,
         collectively,  the  "Subsidiaries")  has  been  duly  organized  and is

         business,  except  where the  failure  so to  qualify  or to be in good
         standing  would not result in a  Material  Adverse  Effect;  except for
         directors'   qualifying  shares  and  as  otherwise  disclosed  in  the

         of each such Subsidiary has been duly authorized and validly issued, is
         fully paid and  non-assessable  and is owned by the  Company or another
         Subsidiary free and clear of any security interest,  mortgage,  pledge,
         lien,  encumbrance,  claim or equity; none of the outstanding shares of
         capital  stock  of  any  Subsidiary  was  issued  in  violation  of the
         preemptive or similar rights of any  securityholder of such Subsidiary.
         The only subsidiaries of the Company are (a) the subsidiaries listed on
         Schedule D hereto and (b) CHKS, S.A., a corporation  (societe  anonyme)
         organized under the laws of France.

         stock of the  Company  is as set  forth  in the  Prospectus  under  the

         employee benefit plans referred to in the Prospectus or pursuant to the
         exercise  of  convertible  securities  or  options  referred  to in the
         Prospectus).  The shares of  outstanding  capital stock of the Company,
         including the Initial  Securities  to be purchased by the  Underwriters
         from the Selling  Stockholders,  have been duly  authorized and validly
         issued and are fully paid and  non-assessable;  none of the outstanding
         shares  of  capital  stock  of  the  Company,   including  the  Initial
         Securities  to be  purchased  by  the  Underwriters  from  the  Selling
         Stockholders,  was  issued  in  violation  of the  preemptive  or other
         similar  rights  of  any  securityholder  of  the  Company  arising  by
         operation of law, under the charter or bylaws of the Company, under any
         agreement to which the Company or any of its subsidiaries is a party or
         otherwise.

                  (ix)  Authorization of Agreement. This Agreement has been duly
         authorized, executed and delivered by the Company.

                  (x)  Authorization  and  Description  of the  Securities.  The
         Securities  to be purchased by the  Underwriters  from the Company have
         been  duly  authorized  for  issuance  and sale by the  Company  to the
         Underwriters  pursuant to this Agreement and, when issued and delivered

         consideration  set forth herein,  will be validly issued and fully paid
         and non-assessable; the

                                       6

<PAGE>



         Common Stock conforms to all statements  relating thereto  contained in
         the Prospectus and such description conforms to the rights set forth in
         the instruments defining the same; and no holder of the Securities will
         be subject to personal  liability by reason of being such a holder; and
         the  issuance of the  Securities  is not subject to the  preemptive  or
         other similar rights of any securityholder of the Company.

                  (xi)  Absence of Defaults and  Conflicts.  Neither the Company
         nor any of its subsidiaries is in violation of its charter or bylaws or
         in  default  in  the  performance  or  observance  of  any  obligation,
         agreement,  covenant or condition contained in any contract, indenture,
         mortgage, deed of trust, loan or credit agreement, note, lease or other
         agreement or instrument to which the Company or any of its subsidiaries
         is a party or by which it or any of them may be bound,  or to which any
         of the property or assets of the Company or any  subsidiary  is subject
         (collectively,  "Agreements and Instruments")  except for such defaults
         that would not result in a Material Adverse Effect;  and the execution,
         delivery  and  performance  of this  Agreement  and  compliance  by the
         Company with its obligations hereunder have been duly authorized by all
         necessary  corporate  action and do not and will not,  whether  with or
         without the giving of notice or passage of time or both,  conflict with
         or  constitute a breach of, or default or  Repayment  Event (as defined
         below)  under,  or result in the  creation or  imposition  of any lien,
         charge or encumbrance upon any property or assets of the Company or any
         subsidiary pursuant to, the Agreements and Instruments (except for such
         conflicts,  breaches or defaults or liens, charges or encumbrances that
         would not result in a Material  Adverse  Effect),  nor will such action
         result in any  violation of the  provisions of the charter or bylaws of
         the Company or any subsidiary or any  applicable  law,  statute,  rule,
         regulation,   judgment,  order,  writ  or  decree  of  any  government,
         government  instrumentality  or  court,  domestic  or  foreign,  having
         jurisdiction over the Company or any subsidiary or any of their assets,
         properties or operations. As used herein, a "Repayment Event" means any
         event or  condition  which gives the holder of any note,  debenture  or
         other evidence of  indebtedness  (or any person acting on such holder's
         behalf) the right to require the repurchase, redemption or repayment of
         all or a portion of such indebtedness by the Company or any subsidiary.

                  (xii)  Absence of Labor  Dispute.  No labor  dispute  with the
         employees of the Company or any Subsidiary  exists or, to the knowledge
         of the  Company,  is  imminent,  and the  Company  is not  aware of any
         existing or imminent  labor  disturbance by the employees of any of its
         or any Subsidiary's  principal suppliers,  manufacturers,  customers or
         contractors,  which,  in either  case,  may  reasonably  be expected to
         result in a Material Adverse Effect.

                  (xiii)  Absence  of  Proceedings.  There is no  action,  suit,
         proceeding,  inquiry or investigation before or brought by any court or
         governmental agency or body, domestic or foreign,  now pending,  or, to
         the  knowledge of the  Company,  threatened,  against or affecting  the
         Company or any  subsidiary,  which is required to be  disclosed  in the
         Registration  Statement  (other than as  disclosed  therein),  or which
         might reasonably be expected to result in a Material Adverse Effect, or
         which might  reasonably be expected to materially and adversely  affect
         the properties or assets  thereof or the  performance by the Company of
         its obligations hereunder; the aggregate of all pending legal or

                                       7

<PAGE>



         governmental  proceedings  to which the Company or any  subsidiary is a
         party or of which  any of their  respective  property  or assets is the
         subject  which  are  not  described  in  the  Registration   Statement,
         including ordinary routine litigation incidental to the business, could
         not reasonably be expected to result in a Material Adverse Effect.

                  (xiv)  Accuracy  of  Exhibits.   There  are  no  contracts  or
         documents  which  are  required  to be  described  in the  Registration
         Statement,  the Prospectus or the documents  incorporated  by reference
         therein  or to be  filed as  exhibits  thereto  which  have not been so
         described or filed as required.

                  (xv) Possession of Intellectual  Property. The Company and its
         subsidiaries  own or  possess  rights  to  use  all  material  patents,
         licenses, inventions, copyrights, know-how (including trade secrets and
         other  unpatented  and/or  unpatentable   proprietary  or  confidential
         information,  systems or procedures),  trademarks, service marks, trade
         names  or  other  intellectual  property  (collectively,  "Intellectual
         Property") necessary to carry on the business now operated by them, and
         neither the Company nor any of its subsidiaries has received any notice
         or is otherwise aware of any  infringement of or conflict with asserted
         rights of others  with  respect  to any  Intellectual  Property,  which
         infringement or conflict (if the subject of any  unfavorable  decision,
         ruling  or  finding)  singly  or in the  aggregate,  would  result in a
         Material Adverse Effect.

                  (xvi)  Absence of Further  Requirements.  No filing  with,  or
         authorization,   approval,   consent,  license,  order,   registration,
         qualification  or decree of,  any court or  governmental  authority  or
         agency is necessary or required for the  performance  by the Company of
         its obligations hereunder, except such as have been already obtained or
         as may be required  under the 1933 Act or the 1933 Act  Regulations  or
         state securities laws.

                  (xvii) Possession of Licenses and Permits. The Company and its
         subsidiaries possess such permits,  licenses,  approvals,  consents and
         other authorizations (collectively,  "Governmental Licenses") issued by
         the appropriate federal, state, local or foreign regulatory agencies or
         bodies  necessary to conduct the  business  now  operated by them;  the
         Company  and its  subsidiaries  are in  compliance  with the  terms and
         conditions of all such Governmental Licenses,  except where the failure
         so to comply  would not,  singly or in the  aggregate,  have a Material
         Adverse Effect; all of the Governmental  Licenses are valid and in full
         force and  effect,  except  when the  invalidity  of such  Governmental
         Licenses  or the  failure of such  Governmental  Licenses to be in full
         force and effect would not have a Material Adverse Effect;  and neither
         the  Company nor any of its  subsidiaries  has  received  any notice of
         proceedings  relating to the  revocation  or  modification  of any such
         Governmental Licenses which, singly or in the aggregate, if the subject
         of an  unfavorable  decision,  ruling  or  finding,  would  result in a
         Material Adverse Effect.

                  (xviii)  Title to Property.  The Company and its  Subsidiaries
         own no real property.  The Company and its Subsidiaries have good title
         to all personal  property owned by them, free and clear of all pledges,
         liens, security interests,  claims, restrictions or encumbrances of any
         kind except such as (a) are described in the  Prospectus or (b) do not,
         singly  or in the  aggregate,  materially  affect  the  value  of  such
         property and do not interfere with the

                                       8

<PAGE>



         use made and proposed to be made of such property by the Company or any
         of its  Subsidiaries;  and all of the leases and subleases  material to
         the  business of the Company and its  subsidiaries,  considered  as one
         enterprise,  and under  which the  Company  or any of its  Subsidiaries
         holds  properties  described in the  Prospectus,  are in full force and
         effect,  and neither the Company nor any  subsidiary  has any notice of
         any material claim of any sort that has been asserted by anyone adverse
         to the rights of the Company or any Subsidiary  under any of the leases
         or subleases mentioned above, or affecting or questioning the rights of
         the  Company or such  Subsidiary  to the  continued  possession  of the
         leased or subleased premises under any such lease or sublease.

                  (xix) Compliance with Cuba Act. The Company has complied with,
         and is and will be in compliance  with,  the provisions of that certain
         Florida  act  relating  to  disclosure  of doing  business  with  Cuba,
         codified as Section 517.075 of the Florida statutes,  and the rules and
         regulations  thereunder  (collectively,  the  "Cuba  Act") or is exempt
         therefrom.

                  (xx)   Registration   Rights.   Except  as  described  in  the
         Registration Statement, there are no persons with registration or other
         similar  rights  to have  any  securities  registered  pursuant  to the
         Registration Statement or otherwise registered by the Company under the
         1933 Act.

                  (xxi)  Income  Taxes.  The Company and its  subsidiaries  have
         filed all Federal, state and foreign income tax returns which have been
         required to be filed,  other than those filings being contested in good
         faith,  and have  paid all  taxes  indicated  by said  returns  and all
         assessments  received  by them or any of them to the  extent  that such
         taxes  become due,  other than those being  contested in good faith and
         for which adequate  reserves have been provided in accordance with GAAP
         or  those  currently  payable  without  penalty  or  interest.  All tax
         liabilities are adequately  provided for on the books of the Company in
         accordance with GAAP.

                  (xxii) Accounting Controls.  The Company maintains a system of
         internal   accounting   controls   sufficient  to  provide   reasonable
         assurances  that (i)  transactions  are  executed  in  accordance  with
         management's general or specific  authorization;  (ii) transactions are
         recorded as necessary to permit preparation of financial  statements in
         conformity with GAAP and to maintain  accountability for assets;  (iii)
         access to assets is  permitted  only in  accordance  with  management's
         general or specific authorization; and (iv) the recorded accountability
         for assets is compared with existing assets at reasonable intervals and
         appropriate action is taken with respect to any differences.

                  (xxiii)  Insurance.  The Company and each of its  Subsidiaries
         and their  respective  properties  are insured in such amounts  against
         such losses and with such insurers as the Company  believes are prudent
         when considered in light of the nature of the properties and businesses
         of the Company and its Subsidiaries.

                  (xxiv)  ERISA  Matters.  The Company is in  compliance  in all
         material  respects  with all  presently  applicable  provisions  of the
         Employee Retirement Income Security Act of 1974, as amended,  including
         the regulations and published interpretations thereunder

                                       9

<PAGE>



         ("ERISA");  no  "reportable  event" (as defined in ERISA) has  occurred
         with respect to any "pension  plan" (as defined in ERISA) for which the
         Company would have any liability; the Company has not incurred and does
         not expect to incur  liability under (i) Title IV of ERISA with respect
         to  termination  of, or  withdrawal  from,  any "pension  plan" or (ii)
         Section 412 or 4971 of the Internal  Revenue Code of 1986,  as amended,
         including the regulations and published interpretations thereunder (the
         "Code");  and each "pension  plan" for which the Company would have any
         liability that is intended to be qualified  under Section 401(a) of the
         Code is so qualified in all material respects and nothing has occurred,
         whether by action or by failure to act,  which  would cause the loss of
         such qualification.

                  (xxv) No Stabilization  or  Manipulation.  The Company has not
         and will not take, directly or indirectly, any action which is designed
         to or which has  constituted  or which might  reasonably be expected to
         cause or result in the  stabilization  or  manipulation of the price of
         the  shares of  Common  Stock to  facilitate  the sale or resale of the
         Securities.

         (b)  Representations and Warranties by the Selling  Stockholders.  Each
Selling Stockholder  severally represents and warrants to each Underwriter as of
the date hereof and as of the Closing  Time  referred to in Section 2(c) hereof,
and agrees with each Underwriter, as follows:

                  (i) Accurate Disclosure.  The Registration Statement, any Rule
         462(b) Registration Statement or any post-effective amendments thereto,
         at the respective  times the  Registration  Statement,  any Rule 462(b)
         Registration Statement or any post-effective  amendments thereto became
         effective,  did not contain an untrue  statement of a material  fact or
         omit to  state  a  material  fact  required  to be  stated  therein  or
         necessary to make the statements therein not misleading. The Prospectus
         or any amendment or supplement  thereto, at the time the Prospectus was
         issued,  at the time any such amended or  supplemented  prospectus  was
         issued or at the Closing  Time,  did not and will not include an untrue
         statement  of a material  fact and did not and will not omit to state a
         material fact necessary in order to make the statements therein, in the
         light of the circumstances  under which they were made, not misleading.
         The foregoing  representations  and warranties in this subsection shall
         apply  only  to  statements  in  or  omissions  from  the  Registration
         Statement (or any amendment thereto) or Prospectus (or any amendment or
         supplement  thereto)  made in  reliance  upon  and in  conformity  with
         information furnished to the Company in writing by or on behalf of such
         Selling Stockholder  expressly for use under the caption "Principal and
         Selling  Stockholders" in the Registration  Statement (or any amendment
         thereto) or Prospectus (or any amendment or supplement  thereto).  Such
         Selling  Stockholder  is not prompted to sell the Securities to be sold
         by  such  Selling   Stockholder   hereunder  by  any  material  adverse
         information concerning HealthVISION or LBA.

                  (ii) Authorization of Agreements. Each Selling Stockholder has
         the full right,  power and authority to enter into this Agreement and a
         Power of Attorney  and Custody  Agreement  (the "Power of Attorney  and
         Custody Agreement") and to sell, transfer and deliver the Securities to
         be sold by such Selling Stockholder hereunder. The execution

                                       10

         Agreement  and the sale and  delivery of the  Securities  to be sold by
         such  Selling  Stockholder  and the  consummation  of the  transactions
         contemplated herein and compliance by such Selling Stockholder with its
         obligations  hereunder  have  been  duly  authorized  by  such  Selling
         Stockholder and do not and will not, whether with or without the giving
         of notice or passage of time or both,  conflict  with or  constitute  a
         breach of, or default under, or result in the creation or imposition of
         any tax, lien,  charge or encumbrance upon the Securities to be sold by
         such  Selling  Stockholder  or any  property or assets of such  Selling
         Stockholder  pursuant to any  contract,  indenture,  mortgage,  deed of
         trust,  loan  or  credit  agreement,  note,  license,  lease  or  other
         agreement or instrument to which such Selling Stockholder is a party or
         by which such Selling  Stockholder may be bound, or to which any of the
         property or assets of such  Selling  Stockholder  is subject,  nor will
         such action result in any violation of the provisions of the charter or
         by-laws or other organizational instrument of such Selling Stockholder,
         or any applicable law, statute, rule, regulation, judgment, order, writ
         or  decree  of any  government,  government  instrumentality  or court,
         domestic or foreign,  having jurisdiction over such Selling Stockholder
         or any of its properties.

                  (iii) Good and Marketable Title. Such Selling  Stockholder has
         and at the  Closing  Time will have  good and  marketable  title to the
         Securities to be sold by such Selling Stockholder  hereunder,  free and
         clear of any security interest,  mortgage, pledge, lien, charge, claim,
         equity  or  encumbrance  of any  kind,  other  than  pursuant  to  this
         Agreement;  and upon  delivery  of such  Securities  and payment of the
         purchase  price  therefor as herein  contemplated,  assuming  each such
         Underwriter   has  no  notice  of  any  adverse  claim,   each  of  the
         Underwriters  will receive good and marketable  title to the Securities
         purchased  by it from such Selling  Stockholder,  free and clear of any
         security interest,  mortgage,  pledge,  lien, charge,  claim, equity or
         encumbrance of any kind.

                  (iv) Due Execution of Power of Attorney and Custody Agreement.
         Such Selling  Stockholder has duly executed and delivered,  in the form
         heretofore  furnished  to the  Underwriters,  the Power of Attorney and

         attorney-in-fact  (in such  capacity,  the  "Attorney-in-Fact")  and as
         custodian  (in  such  capacity,  the  "Custodian");  the  Custodian  is
         authorized  to  deliver  the  Securities  to be sold  by  such  Selling
         Stockholder   hereunder  and  to  accept  payment  therefor;   and  the

         and the certificate referred to in Section 5(f) or that may be required
         pursuant  to Section  5(l) on behalf of such  Selling  Stockholder,  to
         sell, assign and transfer to the Underwriters the Securities to be sold
         by such Selling Stockholder hereunder,  to determine the purchase price
         to be paid by the Underwriters to such Selling Stockholder, as provided
         in Section 2(a) hereof,  to authorize the delivery of the Securities to
         be  sold by such  Selling  Stockholder  hereunder,  to  accept  payment
         therefor, and otherwise to act on behalf of such Selling Stockholder in
         connection with this Agreement.

<PAGE>



                  (v) No Stabilization or Manipulation. Such Selling Stockholder
         has not taken and will not take,  directly  or  indirectly,  any action
         which is designed to or which has constituted or which might reasonably
         be expected to cause or result in the  stabilization or manipulation of
         the price of the Common Stock of the Company to facilitate  the sale or
         resale of the Securities.

                  (vi)  Absence  of Further  Requirements.  No filing  with,  or
         authorization,   approval,   consent,  license,  order,   registration,
         qualification  or decree of,  any court or  governmental  authority  or
         agency,   domestic  or  foreign,  is  necessary  or  required  for  the
         performance by such Selling Stockholder of its obligations hereunder or
         in the Power of Attorney and Custody  Agreement,  or in connection with
         the  sale and  delivery  by such  Selling  Stockholder  of the  Initial
         Securities hereunder or the consummation by such Selling Stockholder of
         the  transactions  contemplated by this  Agreement,  except such as may
         have previously been made or obtained.

         not, without the prior written consent of Merrill Lynch,  offer,  sell,
         contract to sell or otherwise  dispose of, directly or indirectly,  any
         shares of Common Stock,  securities convertible into,  exchangeable for
         or  repayable  with  shares of Common  Stock,  or rights or warrants to
         acquire  shares of Common  Stock or cause to be filed any  registration
         statement under the 1933 Act with respect to any of the foregoing.  The

the Company and delivered to the Underwriters or to counsel for the Underwriters
in  connection   with  the  offering  of  the  Securities   shall  be  deemed  a

<PAGE>



Selling  Stockholder,  at the price per  share  set  forth in  Schedule  C, that
proportion of the number of Initial  Securities set forth in Schedule B opposite
the name of the Company or such Selling  Stockholder,  as the case may be, which
the number of Initial  Securities  set forth in Schedule A opposite  the name of
such Underwriter,  plus any additional  number of Initial  Securities which such
Underwriter  may become  obligated  to purchase  pursuant to the  provisions  of
Section 10 hereof,  bears to the total number of Initial Securities  subject, in
each case, to such  adjustments  among the  Underwriters as the  Underwriters in
their  sole  discretion  shall  make to  eliminate  any  sales or  purchases  of
fractional securities.

         (b)  Option  Securities.  On  the  basis  of  the  representations  and
warranties  herein contained and subject to the terms and conditions  herein set
forth,  the Company hereby grants an option to the  Underwriters,  severally and
not jointly,  to purchase up to an additional 332,505 shares of Common Stock, as
set forth in Schedule B, at the price per share set forth in Schedule C, less an
amount per share equal to any dividends or distributions declared by the Company
and payable on the Initial  Securities but not payable on the Option Securities.
The option  hereby  granted will expire 30 days after the date hereof and may be
exercised in whole or in part from time to time only for the purpose of covering
over-allotments   which  may  be  made  in  connection  with  the  offering  and
distribution of the Initial  Securities  upon notice by the  Underwriters to the
Company  setting  forth the number of Option  Securities as to which the several
Underwriters are then exercising the option and the time and date of payment and
delivery for such Option Securities. Any such time and date of delivery (a "Date
of Delivery")  shall be determined by the  Underwriters,  but shall not be later
than seven full business days (or, in the case of any exercise of said option by
notice given after the Closing Time (as hereinafter  defined),  earlier than two
full business days) after the exercise of said option, nor in any event prior to
the Closing  Time.  If the option is  exercised  as to all or any portion of the
Option Securities,  each of the Underwriters,  acting severally and not jointly,
will purchase  that  proportion  of the total number of Option  Securities  then
being purchased  which the number of Initial  Securities set forth in Schedule A
opposite  the name of such  Underwriter  bears to the total  number  of  Initial
Securities,  subject in each case to such  adjustments  as the  Underwriters  in
their  discretion  shall make to eliminate  any sales or purchases of fractional
shares.

         (c)  Payment.  Payment of the  purchase  price  for,  and  delivery  of
certificates for, the Initial  Securities shall be made at the office of Brown &
Wood LLP, One World Trade  Center,  New York,  New York 10048,  or at such other
place  as shall be  agreed  upon by the  Underwriters  and the  Company  and the
Selling Stockholders,  at 10:00 A.M. (Eastern Time) on the third (fourth, if the
pricing  occurs after 4:30 P.M.  (Eastern  Time) on any given day)  business day
after the date hereof  (unless  postponed in accordance  with the  provisions of
Section 10), or such other time not later than ten business days after such date
as shall be agreed  upon by the  Underwriters  and the  Company  and the Selling
Stockholders  (such time and date of payment and delivery  being  herein  called
"Closing  Time").  In  addition,  in the  event  that  any or all of the  Option
Securities are purchased by the Underwriters, payment of the purchase price for,
and delivery of certificates  for, such Option  Securities  shall be made at the
above-mentioned  offices,  or at such other place as shall be agreed upon by the
Underwriters  and the  Company,  on each Date of  Delivery as  specified  in the
notice from the Underwriters to the Company.


                                       13

<PAGE>



         Payment of the purchase price for the Initial  Securities shall be made
to the Company  and the Selling  Stockholders  by wire  transfer of  immediately
available  funds to the  Company  and the  Custodian  pursuant  to each  Selling
Stockholder's  Power of  Attorney  and  Custody  Agreement,  as the case may be,
against delivery to the Underwriters of certificates for the Initial  Securities
to be purchased by them. Payment of the purchase price for any Option Securities
shall be made to the Company by wire transfer of immediately  available funds to
the Company, against delivery to the Underwriters of certificates for the Option
Securities to be purchased by them. It is understood  that each  Underwriter has
authorized  Merrill Lynch, for its account,  to accept delivery of, receipt for,
and make  payment of the  purchase  price for,  the Initial  Securities  and the
Option  Securities,  if any,  which it has agreed to  purchase.  Merrill  Lynch,
individually and not as representative  of the Underwriters,  may (but shall not
be obligated to) make payment of the purchase  price for the Initial  Securities
or the Option Securities, if any, to be purchased by any Underwriter whose funds
have not been received by the Closing Time or the relevant Date of Delivery,  as
the case may be, but such payment  shall not relieve such  Underwriter  from its
obligations hereunder.

         (d)   Denominations;   Registration.   Certificates   for  the  Initial
Securities and the Option Securities, if any, shall be in such denominations and
registered in such names as the Underwriters may request in writing at least one
full business day before the Closing Time or the relevant  Date of Delivery,  as
the case may be. The  certificates  for the  Initial  Securities  and the Option
Securities,  if any, will be made available for examination and packaging by the
Underwriters in The City of New York not later than 10:00 A.M. (Eastern Time) on
the business day prior to the Closing Time or the relevant Date of Delivery,  as
the case may be.

         SECTION 3.        Covenants of the Company.  The Company covenants with
each Underwriter as follows:

                  (a)  Compliance  with  Securities  Regulations  and Commission
         Requests. The Company, subject to Section 3(b) hereof, will comply with
         the  requirements  of Rule 430A or Rule 434,  as  applicable,  and will
         notify the  Underwriters  promptly,  and confirm the notice in writing,
         (i) when any  post-effective  amendment to the  Registration  Statement
         shall become  effective,  or any  supplement  to the  Prospectus or any
         amended  Prospectus  shall have been filed,  (ii) of the receipt of any
         comments  from  the  Commission   with  respect  to  the   Registration
         Statement,  (iii) of any request by the Commission for any amendment to
         the  Registration  Statement  or any  amendment  or  supplement  to the
         Prospectus or for additional  information,  and (iv) of the issuance by
         the Commission of any stop order  suspending the  effectiveness  of the
         Registration Statement or of any order preventing or suspending the use
         of  any   preliminary   prospectus,   or  of  the   suspension  of  the
         qualification   of  the   Securities   for  offering  or  sale  in  any
         jurisdiction,  or of the initiation or  threatening of any  proceedings
         for any of such purposes.  The Company will promptly effect the filings
         necessary  pursuant to Rule 424(b) and will take such steps as it deems
         necessary  to  ascertain   promptly  whether  the  form  of  prospectus
         transmitted for filing under Rule 424(b) was received for filing by the
         Commission  and,  in the event that it was not, it will  promptly  file
         such  prospectus.  The  Company  will make every  reasonable  effort to
         prevent  the  issuance  of any stop  order  and,  if any stop  order is
         issued, to obtain the lifting thereof at the earliest possible moment.

                                       14

                  (b)  Filing  of   Amendments.   During  the  period  when  the
         Prospectus is required to be delivered  under the 1933 Act, the Company
         will give the  Underwriters  notice of its intention to file or prepare
         any amendment to the Registration Statement (including any filing under
         Rule 462(b)),  any Term Sheet or any amendment,  supplement or revision
         to either the prospectus included in the Registration  Statement at the
         time it became effective or to the Prospectus,  whether pursuant to the
         1933 Act, the 1934 Act, or  otherwise,  will  furnish the  Underwriters
         with copies of any such documents a reasonable  amount of time prior to
         such  proposed  filing or use, as the case may be, and will not file or
         use any such  document  to which the  Underwriters  or counsel  for the
         Underwriters shall reasonably object.

                  (c)  Delivery  of  Registration  Statements.  The  Company has
         furnished or will deliver to Merrill Lynch,  without  charge,  a signed
         copy of the  Registration  Statement  as  originally  filed and of each
         amendment thereto  (including  exhibits filed therewith or incorporated
         by  reference  therein  and  documents  incorporated  or  deemed  to be
         incorporated  by reference  therein) and signed  copies of all consents
         and  certificates  of  experts,  and will  also  deliver  to the  other
         Underwriters  and to counsel for the  Underwriters,  without charge,  a
         conformed copy of the Registration Statement as originally filed and of
         each  amendment   thereto   (including   exhibits  filed  therewith  or
         incorporated by reference therein and documents  incorporated or deemed
         to  be   incorporated  by  reference   therein).   The  copies  of  the
         Registration  Statement  and each  amendment  thereto  furnished to the
         Underwriters  will  be  identical  in  all  material  respects  to  the
         electronically  transmitted  copies  thereof filed with the  Commission
         pursuant to EDGAR, except to the extent permitted by Regulation S-T.

                  (d)  Delivery of  Prospectuses.  The Company has  delivered to
         each  Underwriter,  without charge,  as many copies of each preliminary
         prospectus as such Underwriter  reasonably  requested,  and the Company
         hereby consents to the use of such copies for purposes permitted by the
         1933 Act. The Company will furnish to each Underwriter, without charge,
         during the period when the Prospectus is required to be delivered under
         the 1933 Act or the 1934 Act,  such number of copies of the  Prospectus
         (as  amended  or  supplemented)  as  such  Underwriter  may  reasonably
         request.  The  Prospectus  and any  amendments or  supplements  thereto
         furnished  to the  Underwriters  will  be  identical  in  all  material
         respects to the  electronically  transmitted  copies thereof filed with
         the  Commission  pursuant to EDGAR,  except to the extent  permitted by
         Regulation S-T.

                  (e) Continued  Compliance  with  Securities  Laws. The Company
         will comply with the 1933 Act and the 1933 Act Regulations and the 1934
         Act and the 1934 Act  Regulations so as to permit the completion of the
         distribution  of the Securities as  contemplated  in this Agreement and
         the  Prospectus.  If at any time when a  prospectus  is required by the
         1933 Act to be delivered in  connection  with sales of the  Securities,
         any event shall occur or condition  shall exist as a result of which it
         is necessary, in the reasonable opinion of counsel for the Underwriters
         and counsel for the  Company,  to amend the  Registration  Statement or
         amend or supplement the  Prospectus in order that the  Prospectus  will
         not include any untrue statements of a material fact or omit to state a
         material  fact  necessary in order to make the  statements  therein not
         misleading in the light

                                       15

<PAGE>



         of  the  circumstances  existing  at  the  time  it is  delivered  to a
         purchaser, or if it shall be necessary, in the opinion of such counsel,
         at any  such  time to  amend  the  Registration  Statement  or amend or
         supplement the Prospectus in order to comply with the  requirements  of
         the 1933 Act or the 1933 Act  Regulations,  the Company  will  promptly
         prepare and file with the  Commission,  subject to Section  3(b),  such
         amendment or supplement  as may be necessary to correct such  statement
         or omission or to make the  Registration  Statement  or the  Prospectus
         comply with such  requirements,  and the Company  will  furnish to each
         Underwriter  such number of copies of such  amendment or  supplement as
         such Underwriter may reasonably request.

                  (f)  Blue  Sky  Qualifications.   The  Company  will  use  all
         reasonable  efforts,  in cooperation with the Underwriters,  to qualify
         the Securities  for offering and sale under the  applicable  securities
         laws of such states and other jurisdictions of the United States as the
         Underwriters  may  designate  and to maintain  such  qualifications  in
         effect  for a period  of not less  than one year  from the later of the
         effective  date  of the  Registration  Statement  and any  Rule  462(b)
         Registration Statement;  provided,  however, that the Company shall not
         be  obligated  to file any general  consent to service of process or to
         qualify as a foreign  corporation  or as a dealer in  securities in any
         jurisdiction  in which it is not so qualified  or to subject  itself to
         taxation in respect of doing business in any  jurisdiction  in which it
         is not  otherwise  so  subject.  In  each  jurisdiction  in  which  the
         Securities  have  been  so  qualified,   the  Company  will  file  such
         statements  and  reports  as  may  be  required  by the  laws  of  such
         jurisdiction to continue such  qualification  in effect for a period of
         not less  than one year  from the  effective  date of the  Registration
         Statement and any Rule 462(b) Registration Statement.

                  (g) Rule 158.  The  Company  will  timely  file  such  reports
         pursuant to the 1934 Act as are  necessary  in order to make  generally
         available to its security  holders as soon as  practicable  an earnings
         statement for the purposes of, and to provide the benefits contemplated
         by, the last paragraph of Section 11(a) of the 1933 Act.

                  (h)    Use of Proceeds.  The Company will use the net proceeds
         received by it from the sale of the Securities in the manner  specified
         in the Prospectus under "Use of Proceeds".

                  (i)  Restriction on Sale of Securities.  During a period of 90
         days from the date of the Prospectus, the Company will not, without the
         prior written consent of Merrill Lynch,  (x) offer,  sell,  contract to
         sell or otherwise  dispose of,  directly or  indirectly,  any shares of
         Common  Stock,   securities  convertible  into,   exchangeable  for  or
         repayable with shares of Common Stock, or rights or warrants to acquire
         shares of Common Stock or (y) file any registration statement under the
         1933 Act  with  respect  to any  shares  of  Common  Stock,  securities
         convertible  into,  exchangeable for or repayable with shares of Common
         Stock,  or rights or warrants to acquire  shares of Common  Stock.  The
         foregoing  sentence  shall not apply to (A) options to purchase  Common
         Stock granted  pursuant to the Company's  1994 Stock and Incentive Plan
         and 1995  Non-Employee  Director  Stock Option Plan  referred to in the
         Prospectus;  or (B) shares of Common  Stock  issued  upon  exercise  of
         options  outstanding  at the date of this  Agreement;  or (C) shares of
         Common

                                       16

         Stock  issued  in  connection   with  one  or  more   acquisitions   of
         privately-held companies,  provided that the number of shares so issued
         does not exceed,  in the aggregate,  2,000,000  (subject to appropriate
         adjustment for stock splits,  reverse stock splits and stock dividends)
         and  that  upon  issuance  all  such  shares   constitute   "restricted
         securities"  as defined in Rule  144(a)  under the 1933 Act; or (D) the
         filing  of  registration  statements  on Form  S-4  under  the 1933 Act
         covering, in the aggregate, the registration of not more than 2,000,000
         (subject to  appropriate  adjustment  for stock  splits,  reverse stock
         splits and stock dividends) shares of Common Stock.

                  (j)  Reporting  Requirements.  The Company,  during the period
         when the  Prospectus is required to be delivered  under the 1933 Act or
         the 1934 Act,  will file all  documents  required  to be filed with the
         Commission pursuant to the 1934 Act within the time periods required by
         the 1934 Act and the 1934 Act Regulations.

         SECTION 4.  Payment of  Expenses.  (a)  Expenses.  The  Company and the
Selling  Stockholders  will pay or cause to be paid all expenses incident to the

         SECTION 5. Conditions of Underwriters' Obligations.  The obligations of
the  several  Underwriters   hereunder  are  subject  to  the  accuracy  of  the
representations  and  warranties  of the Company  and the  Selling  Stockholders
contained  in  Section 1  hereof,  to the  accuracy  of the  statements  made in
certificates  of any  officer  of  the  Company  or on  behalf  of  any  Selling
Stockholder  delivered  pursuant to the provisions hereof, to the performance by
the  Company  of its  covenants  and  other  obligations  hereunder,  and to the
following further conditions:

                  (a) Effectiveness of Registration Statement.  The Registration
         Statement, including any Rule 462(b) Registration Statement, has become
         effective   and  at  Closing   Time  no  stop  order   suspending   the
         effectiveness  of the  Registration  Statement  shall have been  issued
         under the 1933 Act or proceedings  therefor  initiated or threatened by
         the  Commission,  and any  request  on the part of the  Commission  for
         additional  information  shall have been  complied  with.  A prospectus
         containing  the Rule 430A  Information  shall  have been filed with the
         Commission  in  accordance  with  Rule  424(b)  (or  a   post-effective
         amendment providing such information shall have been filed and declared
         effective in accordance with the  requirements of Rule 430A) or, if the
         Company has elected to rely upon Rule 434, a Term Sheet shall have been
         filed with the Commission in accordance with Rule 424(b).

                  (b)  Opinion  of  Counsel  for the  Company  and  the  Selling
         Stockholders. At Closing Time, the Underwriters shall have received the
         favorable  opinion,  dated as of Closing Time,  of Whiteford,  Taylor &
         Preston L.L.P.,  counsel for the Company and the Selling  Stockholders,
         in form  and  substance  reasonably  satisfactory  to  counsel  for the
         Underwriters,  to the  effect set forth in Exhibit A hereto and to such
         further effect as counsel to the Underwriters may reasonably request.

                  (c) Opinion of Counsel for Underwriters.  At Closing Time, the
         Underwriters  shall have  received the favorable  opinion,  dated as of
         Closing Time, of Brown & Wood LLP, counsel for the  Underwriters,  with
         respect to the matters  set forth in clauses  (i),  (v) through  (vii),
         inclusive, and the penultimate paragraph of Exhibit A hereto. In giving
         such opinion such counsel may rely,  as to all matters  governed by the
         laws of jurisdictions  other than the law of the State of New York, the
         federal law of the United States and the General Corporation Law of the
         State of  Delaware,  upon the opinions of counsel  satisfactory  to the
         Underwriters. Such counsel may also state that, insofar as such opinion
         involves  factual  matters,  they have relied,  to the extent they deem
         proper,   upon   certificates  of  officers  of  the  Company  and  its
         subsidiaries and certificates of public officials.

                  (d) Officers'  Certificate.  At Closing Time,  there shall not
         have been,  since the date hereof or since the  respective  dates as of
         which  information  is given in the  Prospectus,  any material  adverse
         change in the  condition,  financial or otherwise,  or in the earnings,
         business  affairs  or  business   prospects  of  the  Company  and  its
         subsidiaries  considered as one enterprise,  and the Underwriters shall
         have received a certificate of the President or a Senior Vice President
         of the Company and of the chief financial or chief  accounting  officer
         of the Company,  dated as of Closing Time, to the effect that (i) there
         has been no such material adverse change,  (ii) the representations and
         warranties  of the Company in Section  1(a) hereof are true and correct
         with the same force and effect as

                                       18

         though  expressly made at and as of Closing Time, (iii) the Company has
         complied with all  agreements  and satisfied all conditions on its part
         to be performed or satisfied at or prior to Closing  Time,  and (iv) no
         stop order suspending the  effectiveness of the Registration  Statement
         has  been  issued  and  no  proceedings  for  that  purpose  have  been
         instituted or, to their  knowledge,  are pending or are contemplated by
         the Commission.

                  (e) Certificate of Selling Stockholders.  At Closing Time, the
         Underwriters shall have received a certificate of the  Attorney-in-Fact
         on behalf of each Selling Stockholder, dated as of Closing Time, to the
         effect that (i) the  representations  and  warranties  of each  Selling
         Stockholder  contained in Section 1(b) hereof are true and correct with
         the same force and effect as though expressly made at and as of Closing

         shall be a date not more than three  business  days prior to Closing
         Time.

                  (h)      No Objection.   The  NASD  shall  not have raised any

         representations  and warranties of the Company contained herein and the
         statements in any certificates furnished by the Company hereunder shall
         be true and  correct as of each Date of Delivery  and, at the  relevant

         other party except as provided in Section 4 and except that Sections 1,
         6, 7 and 8 shall survive any such  termination and remain in full force
         and effect.

         SECTION 6.        Indemnification.

         (a)  Indemnification  of  Underwriters.   (1)  The  Company  agrees  to
indemnify  and hold  harmless  each  Underwriter  and each  person,  if any, who
controls  any  Underwriter  within the  meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act as follows:

                  (i) against  any and all loss,  liability,  claim,  damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged   untrue   statement  of  a  material  fact  contained  in  the
         Registration  Statement (or any amendment thereto),  including the Rule
         430A  Information and the Rule 434 Information,  if applicable,  or the
         omission or alleged  omission  therefrom of a material fact required to
         be stated  therein or  necessary  to make the  statements  therein  not
         misleading  or arising out of any untrue  statement  or alleged  untrue
         statement of a material fact contained in any preliminary prospectus or
         the  Prospectus  (or  any  amendment  or  supplement  thereto),  or the
         omission or alleged omission  therefrom of a material fact necessary in
         order to make the statements therein, in the light of the circumstances
         under which they were made, not misleading;

                  (ii) against any and all loss,  liability,  claim,  damage and
         expense whatsoever,  as incurred, to the extent of the aggregate amount
         paid  in  settlement  of  any  litigation,   or  any  investigation  or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim  whatsoever  based upon any such  untrue  statement  or
         omission, or any such alleged untrue statement or omission, referred to
         under (i) above; provided that (subject to Section 6(d) below) any such
         settlement is effected with the written consent of the Company; and

                  (iii)  against  any and all  expense  whatsoever,  as incurred
         (including  the fees and  disbursements  of  counsel  chosen by Merrill
         Lynch),  reasonably  incurred in investigating,  preparing or defending
         against any  litigation,  or any  investigation  or  proceeding  by any
         governmental  agency or body,  commenced  or  threatened,  or any claim
         whatsoever  based upon any such untrue  statement or  omission,  or any
         such alleged untrue statement or omission,  referred to under (i) above
         to the  extent  that any such  expense  is not paid  under  (i) or (ii)
         above;

provided,  however,  that this indemnity  agreement shall not apply to any loss,
liability,  claim,  damage or expense to the  extent  arising  out of any untrue
statement or omission or alleged  untrue  statement or omission made in reliance
upon and in conformity with (x) written information  furnished to the Company by
any  Underwriter  through  Merrill Lynch  expressly for use in the  Registration
Statement (or any amendment  thereto),  including the Rule 430A  Information and
the Rule 434 Information,  if applicable,  or any preliminary  prospectus or the
Prospectus (or any amendment or supplement  thereto) or (y) written  information
furnished  to the Company by or on behalf of any Selling  Stockholder  expressly
for  use  under  the  caption  "Principal  and  Selling   Stockholders"  in  the
Registration  Statement  (or any  amendment  thereto),  including  the Rule 430A
Information  and the Rule 434  Information,  if applicable,  or any  preliminary
prospectus  or the  Prospectus  (or any amendment or  supplement  thereof);  and
provided,  further,  that the  foregoing  indemnity is subject to the  condition
that,  insofar  as it relates to any untrue  statement  or  omission  or alleged
untrue  statement or omission made in any preliminary  prospectus but eliminated
in the

                                       21

<PAGE>



Prospectus (or any amendment or supplement  thereto),  such indemnity  shall not
inure  to the  benefit  of any  Underwriter  (or  any  person  controlling  such
Underwriter) if a copy of such  Prospectus (or amendment or supplement  thereto)
was not  delivered to the person  asserting any such loss,  liability,  claim or
damage,  if such delivery was required by the 1933 Act, and the delivery thereof
would have  cured the  defect  giving  rise to such  loss,  liability,  claim or
damage.

(2) Each Selling Stockholder, severally and not jointly, agrees to indemnify and
hold  harmless  each  Underwriter  and each  person,  if any,  who  controls any
Underwriter  within  the  meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act as follows:

                  (i) against  any and all loss,  liability,  claim,  damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged   untrue   statement  of  a  material  fact  contained  in  the
         Registration  Statement (or any amendment thereto),  including the Rule
         430A  Information and the Rule 434 Information,  if applicable,  or the
         omission or alleged  omission  therefrom of a material fact required to
         be stated  therein or  necessary  to make the  statements  therein  not
         misleading  or arising out of any untrue  statement  or alleged  untrue
         statement of a material fact contained in any preliminary prospectus or
         the  Prospectus  (or  any  amendment  or  supplement  thereto),  or the
         omission or alleged omission  therefrom of a material fact necessary in
         order to make the statements therein, in the light of the circumstances
         under which they were made, not misleading;

                  (ii) against any and all loss,  liability,  claim,  damage and
         expense whatsoever,  as incurred, to the extent of the aggregate amount
         paid  in  settlement  of  any  litigation,   or  any  investigation  or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim  whatsoever  based upon any such  untrue  statement  or
         omission, or any such alleged untrue statement or omission, referred to
         under (i) above; provided that (subject to Section 6(d) below) any such
         settlement  is  effected  with  the  written  consent  of such  Selling
         Stockholder; and

                  (iii)  against  any and all  expense  whatsoever,  as incurred
         (including  the fees and  disbursements  of  counsel  chosen by Merrill
         Lynch),  reasonably  incurred in investigating,  preparing or defending
         against any  litigation,  or any  investigation  or  proceeding  by any
         governmental  agency or body,  commenced  or  threatened,  or any claim
         whatsoever  based upon any such untrue  statement or  omission,  or any
         such alleged untrue statement or omission,  referred to under (i) above
         to the  extent  that any such  expense  is not paid  under  (i) or (ii)
         above;

provided,  however,  that this indemnity agreement shall apply only with respect
to untrue  statements or omissions,  or alleged untrue  statements or omissions,
made in the  Registration  Statement (or any amendment  thereto),  including the
Rule  430A  Information  and the Rule 434  Information,  if  applicable,  or any
preliminary  prospectus  or the  Prospectus  (or  any  amendment  or  supplement
thereto) in reliance upon and in conformity with written  information  furnished
to the Company by or on behalf of such  Selling  Stockholder  expressly  for use
under the caption  "Principal  and  Selling  Stockholders"  in the  Registration
Statement (or any amendment  thereto),  including the Rule 430A  Information and
the Rule 434 Information,  if applicable,  or any preliminary  prospectus or the
Prospectus (or any amendment or supplement thereto); and

                                       22

<PAGE>



provided,  further,  that the  foregoing  indemnity is subject to the  condition
that,  insofar  as it relates to any untrue  statement  or  omission  or alleged
untrue  statement or omission made in any preliminary  prospectus but eliminated
in the Prospectus (or any amendment or supplement thereto), such indemnity shall
not inure to the benefit of any  Underwriter  if a copy of such  Prospectus  (or
amendment or supplement  thereto) was not delivered to the person  asserting any
such loss, liability, claim or damage, if such delivery was required by the 1933
Act, and the delivery  thereof  would have cured the defect  giving rise to such
loss, liability, claim or damage.

         (b)  Indemnification  of Company,  Directors  and  Officers and Selling
Stockholders.  Each Underwriter  severally agrees to indemnify and hold harmless
the Company,  its  directors,  each of its officers who signed the  Registration
Statement,  each Selling Stockholder,  and each person, if any, who controls the
Company or any Selling  Stockholder within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act, against any and all loss,  liability,  claim,
damage and expense  described in the indemnity  contained in  subsection  (a) of
this  Section,  as  incurred,  but only with  respect  to untrue  statements  or
omissions,  or alleged untrue statements or omissions,  made in the Registration
Statement (or any amendment  thereto),  including the Rule 430A  Information and
the Rule 434 Information,  if applicable,  or any preliminary  prospectus or the
Prospectus  (or any  amendment or  supplement  thereto) in reliance  upon and in
conformity with written information furnished to the Company by such Underwriter
through  Merrill Lynch expressly for use in the  Registration  Statement (or any
amendment  thereto) or such  preliminary  prospectus or the  Prospectus  (or any
amendment or supplement thereto).

         (c) Actions against Parties; Notification. Each indemnified party shall
give notice as promptly as reasonably  practicable to each indemnifying party of
any action  commenced  against it in  respect of which  indemnity  may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying  party  from  any  liability  hereunder  to  the  extent  it is not
materially  prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  An  indemnifying  party may  participate  at its own  expense in the
defense  of any such  action.  If it so elects  within a  reasonable  time after
receipt  of  such  notice,  an  indemnifying  party,   jointly  with  any  other
indemnifying  parties  receiving  such  notice,  may assume the  defense of such
action  with  counsel  chosen  by it and  approved  by the  indemnified  parties
defendant in such action,  unless such indemnified  parties reasonably object to
such assumption on the ground that there may be legal defenses available to them
which are different from or in addition to those available to such  indemnifying
party.  If an  indemnifying  party  assumes  the  defense  of such  action,  the
indemnifying  parties  shall not be liable for any fees and  expenses of counsel
for the indemnified  parties incurred thereafter in connection with such action.
In no event shall the  indemnifying  parties be liable for fees and  expenses of
more than one counsel (in addition to any local counsel) separate from their own
counsel  for all  indemnified  parties  in  connection  with any one  action  or
separate but similar or related actions in the same jurisdiction  arising out of
the same general  allegations or  circumstances.  No  indemnifying  party shall,
without  the  prior  written  consent  of the  indemnified  parties,  settle  or
compromise  or  consent  to  the  entry  of any  judgment  with  respect  to any
litigation,  or any  investigation or proceeding by any  governmental  agency or
body,  commenced  or  threatened,  or any claim  whatsoever  in respect of which
indemnification  or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise

                                       23

<PAGE>



or consent (i) includes an unconditional  release of each indemnified party from
all liability arising out of such litigation, investigation, proceeding or claim
and  (ii)  does  not  include  a  statement  as  to or an  admission  of  fault,
culpability or a failure to act by or on behalf of any indemnified party.

         (d) Settlement without Consent if Failure to Reimburse.  If at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified  party for fees and  expenses of counsel,  such  indemnifying  party
agrees that it shall be liable for any settlement of the nature  contemplated by
Section 6(a)(1)(ii) and Section 6(a)(2)(ii) effected without its written consent
if (i) such  settlement  is entered into more than 60 days after receipt by such
indemnifying party of the aforesaid request,  (ii) such indemnifying party shall
have received  notice of the terms of such  settlement at least 45 days prior to
such settlement being entered into and (iii) such  indemnifying  party shall not
have reimbursed such indemnified  party in accordance with such request prior to
the date of such settlement.

         (e) The provisions of this Section shall not affect any agreement among
the Company and the Selling Stockholders with respect to indemnification.

         SECTION 7. Contribution. If the indemnification provided for in Section
6 hereof is for any reason  unavailable to or  insufficient  to hold harmless an
indemnified  party in respect of any  losses,  liabilities,  claims,  damages or
expenses referred to therein,  then each indemnifying  party shall contribute to
the aggregate amount of such losses,  liabilities,  claims, damages and expenses
incurred by such  indemnified  party, as incurred,  (i) in such proportion as is
appropriate  to reflect the  relative  benefits  received by the Company and the
Selling Stockholders on the one hand and the Underwriters on the other hand from
the  offering  of the  Securities  pursuant  to  this  Agreement  or (ii) if the
allocation  provided by clause (i) is not permitted by  applicable  law, in such
proportion as is appropriate to reflect not only the relative  benefits referred
to in clause  (i)  above  but also the  relative  fault of the  Company  and the
Selling  Stockholders on the one hand and of the  Underwriters on the other hand
in connection  with the  statements or omissions  which resulted in such losses,
liabilities,  claims,  damages  or  expenses,  as  well  as any  other  relevant
equitable considerations.

         The  relative   benefits  received  by  the  Company  and  the  Selling
Stockholders  on the  one  hand  and  the  Underwriters  on the  other  hand  in
connection with the offering of the Securities  pursuant to this Agreement shall
be deemed to be in the same  respective  proportions  as the total net  proceeds
from the offering of the Securities pursuant to this Agreement (before deducting
expenses)  received by the Company  and the Selling  Stockholders  and the total
underwriting discount received by the Underwriters, in each case as set forth on
the cover of the Prospectus, or, if Rule 434 is used, the corresponding location
on the Term Sheet bear to the aggregate  initial  public  offering  price of the
Securities as set forth on such cover.

         The relative fault of the Company and the Selling  Stockholders  on the
one hand and the Underwriters on the other hand shall be determined by reference
to, among other things, whether any such untrue or alleged untrue statement of a
material  fact or omission or alleged  omission to state a material fact relates
to information  supplied by the Company or the Selling  Stockholders  on the one
hand or by the Underwriters on the other hand and the parties' relative

                                       24

<PAGE>



intent,  knowledge,  access to information and opportunity to correct or prevent
such statement or omission.

         The Company,  the Selling  Stockholders and the Underwriters agree that
it would not be just and  equitable if  contribution  pursuant to this Section 7
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable  considerations  referred to above in this Section
7. The aggregate  amount of losses,  liabilities,  claims,  damages and expenses
incurred by an  indemnified  party and referred to above in this Section 7 shall
be deemed to include  any legal or other  expenses  reasonably  incurred by such
indemnified  party  in   investigating,   preparing  or  defending  against  any
litigation,  or any  investigation or proceeding by any  governmental  agency or
body,  commenced  or  threatened,  or any claim  whatsoever  based upon any such
untrue or alleged untrue statement or omission or alleged omission.

         Notwithstanding  the provisions of this Section 7, no Underwriter shall
be required to contribute  any amount in excess of the amount by which the total
price at which the Securities  underwritten  by it and distributed to the public
were  offered  to the  public  exceeds  the  amount of any  damages  which  such
Underwriter  has otherwise  been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this  Section 7, each  person,  if any, who controls an
Underwriter  within  the  meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each  director  of the  Company,  each  officer  of the  Company  who signed the
Registration Statement, and each person, if any, who controls the Company or any
Selling  Stockholder within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act shall have the same rights to  contribution as the Company or
such Selling Stockholder, respectively. The Underwriters' respective obligations
to contribute pursuant to this Section 7 are several in proportion to the number
of Initial  Securities set forth opposite their  respective  names in Schedule A
hereto and not joint.

         The  provisions of this Section shall not affect any agreement  between
the Company and the Selling Stockholders with respect to contribution.

         SECTION  8.  Representations,  Warranties  and  Agreements  to  Survive
Delivery.  All  representations,  warranties  and  agreements  contained in this
Agreement  or in  certificates  of  officers  of  the  Company  or  the  Selling
Stockholders submitted pursuant hereto, shall remain operative and in full force
and  effect,  regardless  of  any  investigation  made  by or on  behalf  of any
Underwriter  or  controlling  person,  or by or on behalf of the  Company or the
Selling  Stockholders,  and shall  survive  delivery  of the  Securities  to the
Underwriters.

         SECTION 9.           Termination of Agreement.

         (a)   Termination;   General.   The  Underwriters  may  terminate  this
Agreement, by notice to the Company and the Selling Stockholders, at any time at
or prior to Closing  Time (i) if there has been,  since the time of execution of
this Agreement or since the respective dates as of which information is given in
the  Prospectus,  any material  adverse  change in the  condition,  financial or
otherwise,  or in the earnings,  business  affairs or business  prospects of the
Company and its subsidiaries considered as one enterprise,  or (ii) if there has
occurred  any material  adverse  change in the  financial  markets in the United
States,  any outbreak of hostilities or escalation  thereof or other calamity or
crisis or any change or development  involving a prospective  change in national
or international political,  financial or economic conditions,  in each case the
effect  of  which  is such as to make  it,  in the  reasonable  judgment  of the
Underwriters, impracticable to market the Securities or to enforce contracts for
the sale of the Securities, or (iii) if trading in any securities of the Company
has been suspended or limited by the Commission,  the Nasdaq National Market, or
if  trading  generally  on the  American  Stock  Exchange  or the New York Stock
Exchange or in the Nasdaq  National  Market has been  suspended  or limited,  or
minimum or maximum  prices for trading  have been fixed,  or maximum  ranges for
prices  have been  required,  by any of said  exchanges  or by such system or by
order of the Commission,  the NASD or any other governmental  authority, or (iv)
if a  banking  moratorium  has  been  declared  by  either  Federal  or New York
authorities.

         (b)  Liabilities.  If this  Agreement  is  terminated  pursuant to this
Section,  such termination  shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6, 7 and 8 shall  survive  such  termination  and  remain  in full  force and
effect.

         SECTION 10. Default by One or More of the Underwriters.  If one or more
of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase
the  Securities  which it or they are obligated to purchase under this Agreement
(the "Defaulted  Securities"),  the  non-defaulting  Underwriters shall have the
right,  within 24 hours thereafter,  to make arrangements for one or more of the
non-defaulting Underwriters, or any other underwriters, to purchase all, but not
less than all, of the Defaulted Securities in such amounts as may be agreed upon
and  upon  the  terms  herein  set  forth;  if,  however,   the   non-defaulting
Underwriters  shall not have  completed  such  arrangements  within such 24-hour
period,  then this  Agreement  (or,  with respect to any Date of Delivery  which
occurs after the Closing Time,  the obligation of the  Underwriters  to purchase
and of the Company to sell the Option  Securities  to be  purchased  and sold on
such Date of  Delivery)  shall  terminate  without  liability on the part of any
non-defaulting Underwriter.

         No action taken  pursuant to this Section shall relieve any  defaulting
Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a termination
of this  Agreement  (or,  in the case of a Date of  Delivery  which is after the
Closing Time,  which does not result in a termination  of the  obligation of the
Underwriters to purchase and the Company to sell the relevant Option Securities)
either the non-defaulting  Underwriters or the Selling Stockholders (solely with
respect  to the  Initial  Securities)  or the  Company  shall  have the right to
postpone

                                       26

Closing Time or the relevant Date of Delivery,  as the case may be, for a period
not  exceeding  seven  days in order  to  effect  any  required  changes  in the
Registration  Statement or Prospectus or in any other documents or arrangements.
As used herein,  the term  "Underwriter"  includes any person substituted for an
Underwriter under this Section 10.

         SECTION 11. Default by One or More of the Selling  Stockholders  or the
Company.  (a) If one or more Selling  Stockholders shall fail at Closing Time to
sell and deliver the number of  Securities  which such  Selling  Stockholder  or
Selling  Stockholders  are obligated to sell  hereunder,  the remaining  Selling
Stockholders  shall have the right within 24 hours  thereafter to increase,  pro
rata or otherwise,  the number of Securities to be sold by them hereunder to the
total number to be sold by all Selling  Stockholders  as set forth in Schedule B
hereto;  if, however,  the  non-defaulting  Selling  Stockholders shall not have
exercised such right within such 24-hour period,  then the Underwriters  may, by
notice  from the  Underwriters  to the Company  and the  non-defaulting  Selling
Stockholders,  either (a) terminate this Agreement  without any liability on the
part of any non-defaulting  party,  except that the provisions of Sections 1, 4,
6, 7 and 8 shall  remain in full force and effect,  or (b) elect to purchase the
Securities which the  non-defaulting  Selling  Stockholders and the Company have
agreed to sell  hereunder.  No action  taken  pursuant to this  Section 11 shall
relieve any Selling Stockholder so defaulting from liability, if any, in respect
of such default.

         In the event of a default by any Selling  Stockholder as referred to in
this Section 11, each of the  Underwriters,  the Company and the  non-defaulting
Selling  Stockholders shall have the right to postpone Closing Time for a period
not  exceeding  seven  days in  order  to  effect  any  required  change  in the
Registration Statement or Prospectus or in any other documents or arrangements.

         (b) If the  Company  shall  fail  at  Closing  Time  or at the  Date of
Delivery  to  sell  the  number  of  Securities  that  it is  obligated  to sell
hereunder, then this Agreement shall terminate without any liability on the part
of any nondefaulting party;  provided,  however, that the provisions of Sections
1, 4, 6, 7 and 8 shall remain in full force and effect. No action taken pursuant
to this Section shall relieve the Company from liability,  if any, in respect of
such default.

         SECTION 12.  Notices.  All notices and other  communications  hereunder
shall be in  writing  and shall be  deemed to have been duly  given if mailed or
transmitted  by any  standard  form  of  telecommunication.  Notices  and  other
communications  to the  Underwriters  shall be directed to the  Underwriters c/o

                      FORM OF OPINION OF COMPANY'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                  SECTION 5(b)


           (i) The Company has been duly organized and is validly  existing as a
    corporation in good standing  under the laws of the State of Maryland,  with
    corporate power and authority to own or lease its properties and conduct its
    business as  described in the  Prospectus  and to enter into and perform its
    obligations under the Underwriting Agreement.

           (ii) Each of the  Subsidiaries has been duly organized and is validly
    existing  as  a  corporation   in  good  standing  under  the  laws  of  the
    jurisdiction of its incorporation, with corporate power and authority to own
    or lease its  properties  and  conduct  its  business  as  described  in the
    Prospectus;  the Company and each of the  Subsidiaries are duly qualified to
    transact  business  in all  jurisdictions  in  which  the  conduct  of their
    business  requires such  qualification,  unless the failure to qualify would
    not have a material  adverse  effect on the  business of the Company and its
    subsidiaries  taken as a whole; and the outstanding  shares of capital stock
    of each of the Subsidiaries have been duly authorized and validly issued and
    are  fully  paid  and  non-assessable  and are  owned  by the  Company  or a
    Subsidiary (except for directors' qualifying shares); and, to our knowledge,
    except for the lien in favor of First Union  National Bank of North Carolina
    ("First Union") created under that certain Credit  Agreement dated August 8,
    1996 by and between First Union, as Agent, and the Company,  the outstanding
    shares of capital stock of each of the Subsidiaries are owned free and clear
    of all liens,  encumbrances and security interests, and no options, warrants
    or other rights to purchase,  agreements  or other  obligations  to issue or
    other rights to convert any obligations  into any shares of capital stock or
    of ownership interests in the Subsidiaries are outstanding.

           (iii) The Company has authorized and outstanding capital stock as set
    forth under the caption "Capitalization" in the Prospectus;  the outstanding
    shares of the Company's Common Stock, including the Initial Securities to be
    purchased by the Underwriters from the Selling Stockholders,  have been duly
    authorized and validly issued and are fully paid and non-assessable;  all of
    the Securities conform to the description thereof  incorporated by reference
    in the Prospectus;  the Securities to be sold by the Company pursuant to the
    Underwriting Agreement have been duly authorized and will be validly issued,
    fully paid and  non-assessable  when issued and paid for as  contemplated by
    the Underwriting  Agreement;  and no preemptive rights of stockholders exist
    with respect to any of the Securities or the issue or sale thereof.

           (iv) Except as described in or contemplated by the Prospectus, to our
    knowledge, there are no outstanding securities of the Company convertible or
    exchangeable  into or evidencing  the right to purchase or subscribe for any
    shares of  capital  stock of the  Company  and there are no  outstanding  or
    authorized  options,  warrants  or rights of any  character  obligating  the
    Company  to  issue  any  shares  of its  capital  stock  or  any  securities
    convertible or exchangeable

                                      A-1

<PAGE>



    into or evidencing the right to purchase or subscribe for any shares of such
    stock, provided,  however, that certain former shareholders of CHKS Limited,
    an English private company  limited by shares  ("CHKS"),  have the option to
    require  repayments of  promissory  notes issued by the Company in shares of
    Common Stock in connection with the repurchase of such  shareholders'  stock
    in CHKS by the Company;  and except as described in the  Prospectus,  to our
    knowledge,  there is no holder of any securities of the Company or any other
    person who has the right,  contractual or otherwise, to cause the Company to
    sell or otherwise  issue to them, or to permit them to  underwrite  the sale
    of,  any  shares of Common  Stock or the right to have any  shares of Common
    Stock  or other  securities  of the  Company  included  in the  Registration
    Statement,  or to require  registration  under the 1933 Act of any shares of
    Common Stock or other securities of the Company.

           (v)    The  Underwriting Agreement has been duly authorized, executed
    and delivered by the Company.

           (vi)  The   Registration   Statement,   including   any  Rule  462(b)
    Registration Statement,  has been declared effective under the 1933 Act; any
    required  filing of the Prospectus  pursuant to Rule 424(b) has been made in
    the manner and within the time period  required by Rule 424(b);  and, to the
    best  of our  knowledge  and  information,  no  stop  order  suspending  the
    effectiveness of the  Registration  Statement has been issued under the 1933
    Act or proceedings therefor initiated or threatened by the Commission.

           (vii)  The   Registration   Statement,   including  any  Rule  462(b)
    Registration  Statement,   the  Rule  430A  Information  and  the  Rule  434
    Information,   as  applicable,  the  Prospectus,   excluding  the  documents
    incorporated by reference  therein,  and each amendment or supplement to the
    Registration Statement and Prospectus,  excluding the documents incorporated
    by reference therein, as of their respective effective or issue dates (other
    than the financial  statements,  supporting schedules and other financial or
    statistical  data  included  therein  or omitted  therefrom,  as to which we
    render no opinion)  complied as to form in all  material  respects  with the
    requirements of the 1933 Act and the 1933 Act Regulations.

           (viii) The  documents  incorporated  by reference  in the  Prospectus
    (other  than  the  financial  statements,  supporting  schedules  and  other
    financial or statistical data included therein or omitted  therefrom,  as to
    which we render no opinion),  when they became  effective or were filed with
    the  Commission,  as the case may be,  complied  as to form in all  material
    respects  with  the  requirements  of  the  1933  Act or the  1934  Act,  as
    applicable, and the rules and regulations of the Commission thereunder.

           (ix)  The form of  certificate  used to  evidence  the  Common  Stock
    complies  in  all   material   respects   with  all   applicable   statutory
    requirements, with any applicable requirements of the Charter and By-laws of
    the Company and the requirements of the Nasdaq National Market.

           (x) After  due  inquiry,  including  discussions  with the  Company's
    senior  management  and the  Company's  accountants,  we know of no material
    legal or governmental proceedings

                                      A-2

<PAGE>



    pending or threatened against the Company or any of the subsidiaries  except
    as set forth in the Prospectus.

           (xi) The statements under the captions "Risk  Factors--Dependence  on
    Intellectual   Property  Rights",   "Use  of  Proceeds,"   "Business--Recent
    Acquisitions;  Decision Support Systems;  Customers;  Intellectual Property;
    Government Regulation; Properties; Litigation",  "Management" and "Principal
    and  Selling  Stockholders",  in  the  Prospectus,  and  under  the  caption
    "Description  of Capital Stock" in the Company's  Registration  Statement on
    Form 8-A filed on January 13, 1995, insofar as such statements  constitute a
    summary of  documents  referred to therein or matters of law,  are  accurate
    summaries and fairly present in all material respects the information called
    for with respect to such  documents  and matters;  and there are no material
    statutes,  rules or  regulations  (including  any relating to health care or
    similar  matters) that are not described or referred to therein and that are
    necessary to make the  statements  in the  Prospectus  in the light in which
    they were made not materially misleading.

           (xii) We know of no contracts  or  documents  required to be filed as
    exhibits to the  Registration  Statement or  described  in the  Registration
    Statement or the Prospectus which are not so filed or described as required,
    and such  contracts  and  documents as are  summarized  in the  Registration
    Statement or the Prospectus are fairly summarized in all material respects.

           (xiii) To our  knowledge,  neither the Company or any  subsidiary  is
    presently  in breach  of, or in  default  under,  their  respective  Charter
    documents or Bylaws,  or any provision of any indenture,  mortgage,  deed of
    trust, loan agreement,  bond, debenture, note agreement or other evidence of
    indebtedness or any other agreement, lease, contract, instrument, franchise,
    license, authorization,  permit, approval,  registration,  judgment, decree,
    order,  statute,  rule or regulation of which we have knowledge to which the
    Company  or any  subsidiary  is a party  or by which  any of its  respective
    properties is bound,  which breach or default is material to the business or
    financial  condition of the Company and its  subsidiaries  taken as a whole,
    and to our knowledge,  the Company and its subsidiaries are conducting their
    respective businesses in compliance with all of the material laws, rules and
    regulations  applicable thereto except where  non-compliance,  together with
    all other  such  instances  of  non-compliance,  would  not have a  material
    adverse effect on the business,  properties,  rights, assets,  operations or
    condition (financial or otherwise) of the Company and its subsidiaries taken
    as a whole.

           (xiv)  No  approval,  consent,  order,  authorization,   designation,
    declaration  or filing by or with any  regulatory,  administrative  or other
    governmental body is necessary in connection with the execution and delivery
    of the  Underwriting  Agreement by the Company and the  consummation  by the
    Company  of the  transactions  therein  contemplated  (other  than as may be
    required  by state  securities  and Blue Sky laws as to which we  express no
    opinion), except such as have been obtained or made.

           (xv) The execution and delivery of the Underwriting  Agreement by the
    Company and the consummation of the transactions therein contemplated do not
    and will not  conflict  with or  result  in a breach  of any of the terms or
    provisions of, or constitute a default  under,  the Charter or Bylaws of the
    Company,  or any agreement or instrument known to us to which the Company or
    any of its subsidiaries is a party or by which the Company or any of the

                                      A-3

<PAGE>



    subsidiaries  may be bound,  except to the  extent  that any such  conflict,
    breach or default would not have a material  adverse effect on the earnings,
    business,  management,  properties,  assets, rights,  operations,  condition
    (financial  or  otherwise)  or  business  prospects  of the  Company and its
    subsidiaries taken as a whole.

           (xvi)  The  Company  is  not an  "investment  company"  or an  entity
    "controlled"  by an  "investment  company," as such terms are defined in the
    Investment Company Act of 1940, as amended.

           (xvii) To our  knowledge,  each of the Company  and its  subsidiaries
    owns,  or is  licensed  or  otherwise  has  sufficient  right  to  use,  all
    proprietary knowledge,  data bases, inventions,  trademarks,  service marks,
    logo marks and  copyrights  (collectively,  the "rights")  necessary for the
    conduct of its business as described in the Prospectus. To our knowledge, no
    claims have been asserted  against the Company or any of its subsidiaries by
    any person to the use of any such rights or challenging  or questioning  the
    validity or  effectiveness  of any such rights.  The use, in connection with
    the business and  operations  of the Company and its  subsidiaries,  of such
    rights does not, to our  knowledge,  infringe on the rights of any person or
    entity.

           (xviii) No filing with, or consent, approval, authorization, license,
    order,  registration,  qualification or decree of, any court or governmental
    authority  or agency,  domestic or foreign,  (other than the issuance of the
    order of the Commission  declaring the Registration  Statement effective and
    such  authorizations,  approvals or consents as may be necessary under state
    securities laws, as to which we express no opinion) is necessary or required
    to be obtained  by the  Selling  Stockholders  for the  performance  by each
    Selling  Stockholder of its obligations under the Underwriting  Agreement or
    in the Power of Attorney and Custody  Agreement,  or in connection  with the
    offer, sale or delivery of the Securities.

           (xix) Each Power of  Attorney  and  Custody  Agreement  has been duly
    executed and delivered by the respective  Selling  Stockholder named therein
    and  constitutes  the legal,  valid and binding  agreement  of such  Selling
    Stockholder.

           (xx) The Underwriting  Agreement has been duly  authorized,  executed
    and delivered by or on behalf of each Selling Stockholder.

           (xxi) The  Attorney-in-Fact  has been duly  authorized by the Selling
    Stockholders to deliver the Securities on behalf of the Selling Stockholders
    in accordance with the terms of the Underwriting Agreement.

           (xxii)  The  execution,  delivery  and  performance  by  the  Selling
    Stockholders  of the  Underwriting  Agreement  and the Power of Attorney and
    Custody Agreements and the sale and delivery of the Securities to be sold by
    the Selling Stockholders and the consummation by the Selling Stockholders of
    the  transactions  contemplated  in the  Underwriting  Agreement  and in the
    Registration Statement and compliance by the Selling Stockholders with their
    obligations  under the  Underwriting  Agreement have been duly authorized by
    all necessary action on the part of each Selling  Stockholder and do not and
    will not, whether with or without the giving of notice or passage of time or
    both, conflict with or constitute a breach of, or default under

                                      A-4

<PAGE>



    or  result  in the  creation  or  imposition  of any tax,  lien,  charge  or
    encumbrance  upon the Securities to be sold by the Selling  Stockholders  or
    any property or assets of any Selling Stockholder pursuant to, any contract,
    indenture, mortgage, deed of trust, loan or credit agreement, note, license,
    lease or other instrument or agreement to which any Selling Stockholder is a
    party or by which any Selling  Stockholder  may be bound, or to which any of
    the  property or assets of any Selling  Stockholder  may be subject nor will
    such action  result in any  violation  of the  provisions  of the charter or
    by-laws or other organizational  instrument of any Selling  Stockholder,  or
    any law,  administrative  regulation,  judgment or order of any governmental
    agency or body or any  administrative  or court decree  having  jurisdiction
    over any Selling Stockholder or any Selling Stockholder's properties.

           (xxiii) To our knowledge,  each Selling Stockholder has all rights in
    and to the Securities to be sold by such Selling Stockholder, free and clear
    of any "adverse  claims" within the meaning of Section 8-302 of the New York
    Uniform Commercial Code, and full right and authority to effect the sale and
    delivery of such Securities;  and upon delivery of the Securities to be sold
    by each Selling  Stockholder  and payment of the purchase  price therefor as
    contemplated   in  the   Underwriting   Agreement,   assuming  each  of  the
    Underwriters  is a "bona fide  purchaser" (as defined under Section 8-302 of
    the New York Uniform Commercial Code), each of the Underwriters will acquire
    all  rights  in and to the  Securities  purchased  by it from  each  Selling
    Stockholder,  free and clear of any "adverse  claims"  within the meaning of
    Section 8-302 of the New York Uniform Commercial Code.

           Nothing has come to our attention  that would lead us to believe that
    the  Registration  Statement or any amendment  thereto,  including Rule 430A
    Information and Rule 434 Information (if applicable),  (except for financial
    statements and schedules and other  financial or  statistical  data included
    therein or omitted therefrom, as to which we make no statement), at the time
    such  Registration   Statement  or  any  such  amendment  became  effective,
    contained  an untrue  statement  of a  material  fact or  omitted to state a
    material  fact  required  to be  stated  therein  or  necessary  to make the
    statements therein not misleading or that the Prospectus or any amendment or
    supplement thereto (except for financial  statements and schedules and other
    financial or statistical data included therein or omitted  therefrom,  as to
    which we make no statement),  at the time the Prospectus was issued,  at the
    time any such  amended  or  supplemented  prospectus  was  issued  or at the
    Closing Time, included or includes an untrue statement of a material fact or
    omitted or omits to state a  material  fact  necessary  in order to make the
    statements  therein, in the light of the circumstances under which they were
    made, not misleading.

    [In  rendering  such  opinion,  such  counsel may (A) rely as to all matters
involving the  application  of laws other than the laws of the State of Maryland
or the federal laws of the United States of America,  to the extent such counsel
deems proper and  specified in such  opinion,  upon the opinion of other counsel
whom such counsel believes to be reliable,  provided that such counsel furnishes
a copy  thereof to the  Underwriters  and states that such opinion of such local
counsel is  satisfactory  in form and  substance and that the  Underwriters  and
counsel for the Underwriters  are entitled to rely thereon,  (B) assume that the
laws of the State of New York, to the extent applicable to such opinion, will be
applied in a manner  similar  to, and  consistent  with the laws of the State of
Maryland, and (C) rely as to matters of fact, to the extent such counsel

                                      A-5

deems  proper,  on  certificates  of  responsible  officers  of the Company, its
subsidiaries, the Selling Stockholders and public officials.]

                  the  power to do any and all acts and  things  which a natural
                  person or partnership could do, as now or hereafter authorized
                  by law,  either alone or in partnership  or  conjunction  with
                  others.  In  furtherance  and not in  limitation of the powers
                  conferred by statute, the powers of the Corporation and of its
                  Board  of  Directors  and   stockholders   shall  include  the
                  following:

                           (a) The  Board of  Directors  of the  Corporation  is
                  hereby  empowered to authorize  the issuance from time to time
                  of shares of its stock of any class,  whether now or hereafter
                  authorized,  and  securities  convertible  into  shares of its
                  stock,  of any  class or  classes,  whether  now or  hereafter
                  authorized,  for such  consideration as the Board of Directors
                  may deem advisable.

                           (b) No contract  or other  transaction  between  this
                  Corporation and any other corporation, partnership, individual
                  or other  entity and no act of this  Corporation  shall in any
                  way be  affected  or  invalidated  by the fact that any of the
                  directors  of  this  Corporation  are  directors,  principals,
                  partners or officers of such other entity, or have a pecuniary
                  or otherwise are interested in such  contract,  transaction or
                  act;  provided that: (i) the existence of such relationship or
                  such interest  shall be disclosed to the Board of Directors or
                  to a  committee  of the  Board  of  Directors  if  the  matter
                  involves a committee decision,  and the contract,  transaction
                  or act shall be authorized, approved or ratified by a majority
                  of disinterested  directors on the Board or on such committee,
                  as the  case  may be,  even  if the  number  of  disinterested
                  directors   constitutes  less  than  a  quorum;  or  (ii)  the
                  contract, transaction or act shall be authorized,  ratified or

                                       2

<PAGE>

                  approved in any other manner permitted by the Maryland General
                  Corporation law.

                           (c) The Corporation  reserves the right to make, from
                  time to time,  any  amendments to its Charter which may now or
                  hereafter be authorized by law, including any amendments which
                  alter the contract rights of any class of outstanding stock as
                  expressly set forth in the Charter.

                           (d) The Board of  Directors  shall  have the power to
                  classify or  reclassify  any  unissued  stock,  whether now or
                  hereafter authorized,  by setting or changing the preferences,
                  conversion  or  other  rights,  voting  powers,  restrictions,
                  limitations  as  to  dividends,  qualifications  or  terms  or
                  conditions of redemption of such stock.

                           (e)  Notwithstanding  any  provision of law requiring
                  any action to be taken or authorized by the  affirmative  vote
                  of the holders of a designated  proportion of the votes of all
                  classes  or of any  class of stock  of the  Corporation,  such
                  action shall be effective  and valid if taken or authorized by
                  the  affirmative  vote of a  majority  of the total  number of
                  votes  entitled  to  be  cast  thereon,  except  as  otherwise
                  provided in this Charter.

                  SEVENTH:  Unless otherwise provided by the Board of Directors,
                  no holder of stock of any class or any other security shall be
                  entitled to preemptive  rights to subscribe for or purchase or
                  receive  any part of any new or  additional  issue of stock of
                  any class of the  Corporation or securities  convertible  into
                  stock of any class of the Corporation; provided, however, that
                  the Board of  Directors  may, in  authorizing  the issuance of
                  stock of any class, confer any preemptive right that the Board
                  of  Directors  may deem  advisable  in  connection  with  such
                  issuance,  and set the price and any other  terms the Board of
                  Directors, in its sole discretion, may fix.

                  EIGHTH: To the fullest extent permitted by Maryland  statutory
                  or decisional law, as amended or  interpreted,  no director or
                  officer of this Corporation  shall be personally liable to the
                  Corporation  or  its  stockholders   for  money  damages.   No
                  amendment of the Charter of the  Corporation  or repeal of any

                                LETTERS OF CREDIT

to and on the terms and  conditions of this  Agreement,  to make a loan (each, a

to the  Borrower,  from time to time on any  Business Day during the period from

such time  would  exceed the Total  Revolving  Credit  Commitment,  and (iii) no
advance of any  Borrowing  of  Revolving  Credit  Loans  shall be  required  if,
immediately  after giving effect thereto,  a Default or Event of Default exists.
Subject to and on the terms and conditions of this  Agreement,  the Borrower may
borrow,  repay and reborrow  Revolving  Credit Loans until the Revolving  Credit
Facility Termination Date.

         2.2.         Borrowings.

         (a) The Loans  shall,  at the option of the Borrower and subject to the
terms and conditions of this Agreement, be either Base Rate Loans or LIBOR Loans
(each such type of Loan, a "Type"),  provided that (i) all Loans  comprising the
same Borrowing shall, unless otherwise  specifically  provided herein, be of the
same Type and (ii)  notwithstanding  any other provision of this Agreement,  all
Loans made prior to the third (3rd) Business Day after the Closing Date shall be
made initially as Base Rate Loans.

         (b)  In  order  to  make  a  Borrowing  (other  than  continuations  of
outstanding  Loans which shall be made  pursuant to Section  2.9),  the Borrower
will give the Agent written notice (by telecopier or otherwise),  not later than
11:00 a.m.,  Charlotte,  North  Carolina local time, at least three (3) Business
Days prior to each Borrowing to be comprised of LIBOR Loans and at least one (1)
Business  Day  prior to each  Borrowing  to be  comprised  of Base  Rate  Loans;
provided,  however,  that  requests for the  Borrowing of the Term Loans and any
Revolving  Credit Loans to be made on the Closing Date may, at the discretion of
the Agent, be given later than the times specified hereinabove. Each such notice
(each, a "Notice of Borrowing") shall be irrevocable, shall be given in the form
of Exhibit B-1 and shall be appropriately  completed to specify (i) the Facility
under which such Borrowing is to be made,  (ii) the aggregate  principal  amount
and Type of the Loans to be made pursuant to such Borrowing (and, in the case of
a  Borrowing  of LIBOR  Loans,  the  initial  Interest  Period to be  applicable
thereto),  (iii) the proposed use of the proceeds of the Borrowing, and (iv) the
requested  date of the  Borrowing  (the  "Borrowing  Date"),  which  shall  be a
Business Day.

         Notwithstanding anything to the contrary contained herein:

                           (i) the aggregate  principal amount of each Borrowing
         hereunder (y) in the case of  Borrowings  comprised of Base Rate Loans,
         shall  not be less  than  $500,000  and,  if  greater,  shall  be in an
         integral multiple of $250,000 in excess thereof, and (z) in the case of
         Borrowings  comprised of LIBOR Loans, shall not be less than $5,000,000
         and, if  greater,  shall be in an integral  multiple of  $1,000,000  in
         excess thereof (or, in all cases of a Borrowing of Revolving  Loans, if
         less,  in the  amount  of the  aggregate  Unutilized  Revolving  Credit
         Commitments);


                                                       -25-

<PAGE>




                          (ii) if the  Borrower  shall have failed to  designate
         the Type of Loans comprising a Borrowing,  the Borrower shall be deemed
         to have requested a Borrowing comprised of Base Rate Loans;

                         (iii) if the  Borrower  shall have failed to select the
         duration of the Interest  Period to be  applicable  to any Borrowing of
         LIBOR  Loans,  then the  Borrower  shall be deemed to have  selected an
         Interest Period with a duration of one month; and

                          (iv) LIBOR Loans under the Revolving  Credit  Facility
         may not be  outstanding  under  more than three (3)  separate  Interest
         Periods at any one time and LIBOR  Loans  under the Term Loan  Facility
         may not be  outstanding  under  more than three (3)  separate  Interest
         Periods at any one time.

         (c) Upon its receipt of a Notice of Borrowing,  the Agent will promptly
notify each Lender with a Commitment under the relevant Facility of the proposed
Borrowing.  Not later than 1:00 p.m., Charlotte time, on the requested Borrowing
Date,  each such Lender will make available to the Agent at its office  referred
to in Section  10.4 (or at such other  location as the Agent may  designate)  an
amount,  in Dollars and in immediately  available funds,  equal to the amount of
the Loan to be made by such Lender. To the extent the relevant Lenders have made
such amounts available to the Agent as provided hereinabove, the Agent will make
the  aggregate of such amounts  available  to the  Borrower in  accordance  with
subsection  (d) below and in like funds as  received  by the Agent.  Each Lender
may, at its option,  make and maintain any LIBOR Loan by causing any domestic or
foreign  branch or Affiliate of such Lender to make or maintain such LIBOR Loan,
provided that any exercise of such option shall not affect the obligation of the
Borrower to repay such Loan in accordance with the terms of this Agreement.

         (d) The Borrower  hereby  authorizes the Agent to disburse the proceeds
of each Borrowing in accordance with the terms of any written  instructions from
any of the Authorized  Officers,  provided that the Agent shall not be obligated
under any  circumstances  to  forward  amounts to any  account  not listed in an
Account Designation Letter. The Borrower may at any time deliver to the Agent an
Account  Designation  Letter  listing any  additional  accounts or deleting  any
accounts listed in a previous Account Designation Letter.

         (e) Unless the Agent has received,  prior to 1:00 p.m., Charlotte time,
on the relevant  Borrowing  Date,  written notice from a Lender that such Lender
will not make available to the Agent such Lender's ratable  portion,  if any, of
the  relevant  Borrowing,  the Agent may assume  that such  Lender has made such
portion available to the Agent in immediately  available funds on such Borrowing
Date


                                                       -26-

<PAGE>



in accordance  with  subsection  (c) above,  and the Agent may, in reliance upon
such assumption,  make a corresponding  amount available to the Borrower on such
Borrowing  Date.  If and to the extent that such Lender shall not have made such
portion available to the Agent, and the Agent shall have made such corresponding
amount  available  to the  Borrower,  such  Lender,  on the  one  hand,  and the
Borrower, on the other,  severally agree to pay to the Agent forthwith on demand
such corresponding amount,  together with interest thereon for each day from the
date such amount is made available to the Borrower until the date such amount is
repaid to the Agent, (i) in the case of such Lender,  at the Federal Funds Rate,
and (ii) in the case of the Borrower, at the rate of interest applicable at such
time to Loans  comprising such Borrowing,  as determined under the provisions of
Section 2.6. If such Lender shall repay to the Agent such corresponding  amount,
such amount shall  constitute  such Lender's Loan as part of such  Borrowing for
purposes of this Agreement.  The failure of any Lender to make any Loan required
to be made by it as part of any Borrowing  shall not relieve any other Lender of
its  obligation,  if any,  hereunder to make its Loan as part of such Borrowing,
but no Lender shall be  responsible  for the failure of any other Lender to make
the Loan to be made by such other Lender as part of any Borrowing.

         2.3.         Notes.

         (a) The Loans made by each Lender shall be evidenced (i) if Term Loans,
by a Term Note appropriately completed in substantially the form of Exhibit A-1,
and (ii) if Revolving  Credit Loans,  by a Revolving  Credit Note  appropriately
completed in substantially the form of Exhibit A-2.

         (b) The Term Note  issued to each  Lender  with a Term Loan  Commitment
shall (i) be  executed  by the  Borrower,  (ii) be  payable to the order of such
Lender,  (iii) be dated as of the  Closing  Date (or,  in the case of Term Notes
issued pursuant to an Assignment and Acceptance,  as of the date thereof),  (iv)
be in a stated principal amount equal to such Lender's Term Loan Commitment, (v)
bear interest in accordance  with the provisions of Section 2.6, as the same may
be applicable to the Term Loans made by such Lender from time to time,  and (vi)
be  entitled  to all of the  benefits  of  this  Agreement  and the  other  Loan
Documents and subject to the provisions hereof and thereof.

Credit Commitment shall (i) be executed by the Borrower,  (ii) be payable to the

the date thereof),  (iv) be in a stated  principal amount equal to such Lender's
Revolving Credit Commitment, (v) bear interest in accordance with the provisions

         (d) Each Lender will record on its internal  records the amount of each
Loan made by it and each payment  received by it in respect thereof and will, in
the event of any  transfer  of any of its Notes,  either  endorse on the reverse
side thereof or on a schedule attached thereto (or any continuation thereof) the
outstanding  principal  amount of the Loans evidenced  thereby as of the date of
transfer or provide such information on Annex I to the Assignment and Acceptance
relating to such transfer;  provided, however, that the failure of any Lender to
make any such recordation or provide any such information,  or any error in such
recordation  or  information,  shall not affect the  Borrower's  obligations  in
respect of such  Loans.  The  register  maintained  by the Agent shall be deemed
correct absent manifest error.

         2.4.         Termination and Reduction of Commitments.

         (a)  The   Lenders'   obligation   to  advance   Term  Loans  shall  be
automatically and permanently terminated at 5:00 p.m., Charlotte time, on August
13, 1996.

         (b) The Lenders'  obligation to advance Revolving Credit Loans shall be
automatically  and  permanently  terminated  on the  Revolving  Credit  Facility
Termination Date unless sooner terminated
pursuant to subsection (d) below or Section 8.1.

         (c) The Revolving Credit  Commitment of each Lender shall be reduced as
of 12:01  a.m.  on July 31 in the years set out below in the  amounts  set forth
opposite such years, such amounts expressed as a percentage of the amount of the
Revolving Credit Commitment of each Lender as of the Closing Date:

                      Year                           Percentage Reduction

                      1999                                        25%
                      2000                                        25%

         (d) At any time and from time to time,  upon at least five (5) Business
Days' prior written notice to the Agent,  the Borrower may terminate in whole or
reduce in part the Total Unutilized  Revolving Credit Commitment,  provided that
any such  partial  reduction  shall be in an  aggregate  amount of not less than
$250,000 or, if greater, integral multiples in excess thereof. The amount of any
termination  or reduction  made under this  subsection (d) may not thereafter be
reinstated.

         (e)          Each reduction of the Revolving Credit Commitment under
this Section 2.4 shall be applied ratably among the Lenders according to their
relative Revolving Credit Commitments.  After


                                                       -28-

any such reduction, the fee provided in Sections 2.7(b) shall be calculated with
respect to the reduced Commitments.

         2.5.         Payments; Voluntary, Mandatory.

         (a) At any time and from  time to time,  the  Borrower  shall  have the
right to prepay  the  Loans,  in whole or in part,  without  premium  or penalty
(except as provided in clause (iii)  below),  upon  written  notice to the Agent
given not later than 11:00 a.m., Charlotte time, five (5) Business Days prior to
each intended prepayment,  provided that (i) each partial prepayment shall be in
an  aggregate  principal  amount of not less than  $500,000  or, if greater,  an
integral multiple of $250,000 in excess thereof,  (ii) no partial  prepayment of
LIBOR Loans made  pursuant to any single  Borrowing  shall reduce the  aggregate
outstanding  principal  amount of the remaining LIBOR Loans under such Borrowing
to less than  $5,000,000  or to any greater  amount not an integral  multiple of
$1,000,000  in excess  thereof,  and (iii) unless made together with all amounts
required  under Section 2.13 to be paid as a consequence of such  prepayment,  a
prepayment  of a LIBOR  Loan may be made  only on the  last day of the  Interest
Period applicable  thereto.  Each such notice shall specify the proposed date of
such prepayment and the aggregate principal amount and the Types of the Loans to
be  prepaid  (and,  in the case of  LIBOR  Loans,  the  Interest  Period  of the
Borrowing  pursuant to which made),  and shall be irrevocable and shall bind the
Borrower to make such prepayment on the terms specified therein.  Upon and after
the  occurrence  of an Event of Default or if the  Borrower  has not  designated
allocations,  all prepayments  pursuant to this subsection (a) shall be applied,
first, to the Term Loans, in inverse order of maturity, and then upon payment in
full of the Term Loans,  to the Revolving  Loans.  Revolving Loans (but not Term
Loans) prepaid pursuant to this subsection (a) may be reborrowed, subject to the
terms and conditions of this Agreement.

         (b) Each  prepayment of the Term Loans made pursuant to subsection  (a)
above shall be applied to reduce the aggregate  outstanding  principal amount of
the Term Loans,  ratably  among the Lenders  holding Term Loans in proportion to
the  principal  amount held by each,  with such  reduction  to be applied to the
scheduled principal payments on the Term Loans due under Section 2.5(c) on a pro
rata basis.  Each  prepayment of the Revolving Loans made pursuant to subsection
(a) above shall be applied to reduce the aggregate  outstanding principal amount
of the Revolving  Loans,  ratably among the Lenders  holding  Revolving Loans in
proportion to the principal amount held by each.

         (c) Except to the extent due or made sooner  pursuant to the provisions
of this Agreement,  the Borrower will repay the aggregate  outstanding principal
of the Term Loans in the amounts and on the dates set forth below:



                                                       -29-

                 Date                              Payment

             July 31, 1997                       $10,000,000
             July 31, 1998                       $10,000,000
             July 31, 1999                       $10,000,000
             July 31, 2000                       $10,000,000
             July 31, 2001                       $10,000,000

To the extent not previously  paid, the aggregate  outstanding  principal of the
Term Loans shall be due and payable on the Term Loan Facility Maturity Date.

         (d) Except to the extent due or made sooner  pursuant to the provisions
of this Agreement,  the Borrower will repay the aggregate  outstanding principal
amount of the Revolving Loans in full on the Revolving Credit Facility  Maturity
Date.

         (e) In the  event  that,  at any  time,  the sum of (i)  the  aggregate
principal amount of the Revolving Credit Loans outstanding on any date plus (ii)
the  aggregate  Letter of Credit  Outstandings  at such time  exceeds  the Total
Revolving Credit Commitment at such time (after giving effect to any termination
or reduction  thereof as of such date), the Borrower will immediately  repay the
principal  amount of the  Revolving  Credit  Loans on such date in the amount of
such excess; provided that, (A) such payment shall be accompanied by all amounts
required  under  Section 2.13 if applied to a LIBOR Loan and such payment is not
made on the last day of the Interest Period applicable  thereto,  and (B) to the
extent such excess  amount  required to be repaid is greater than the  aggregate
principal amount of the Revolving Credit Loans outstanding  immediately prior to
the application of such repayment, the amount so repaid shall be retained by the
Agent and held in the Cash  Collateral  Account as security  for the  Borrower's
Reimbursement  Obligations,  as more particularly  described in Section 2.17(i),
and thereupon  such cash shall be deemed to reduce the  aggregate  Reimbursement
Obligations by an equivalent amount.

         (f) On the date of receipt by the  Borrower or any of its  Subsidiaries
of any net cash proceeds from any issuance of equity  securities,  other than an
equity  infusion  for the sole purpose of funding a Permitted  Acquisition,  the
Borrower  shall make a mandatory  repayment of principal of the Term Loans in an
amount equal to one hundred percent (100%) of such net cash proceeds (net of any
underwriting  discounts and commissions and other  reasonable  costs  associated
with such issuance).

         (g) On the date of receipt by the  Borrower or any of its  Subsidiaries
of any net cash  proceeds  from any sale or  disposition  of assets,  other than
sales or dispositions  permitted under clauses (i), (ii) and (iv) of Section 6.5
or the sale of permitted  temporary  overnight  investments,  the Borrower shall
make a


                                                       -30-

<PAGE>



mandatory  repayment  of  principal  of the  Term  Loans in an  amount  equal to
one-hundred percent (100%) of such net cash proceeds.

         (h) Each  prepayment of the Loans made pursuant to subsections  (f) and
(g) above shall be applied to reduce the aggregate  outstanding principal amount
of the Term Loans, ratably among the Lenders holding Term Loans in proportion to
the  principal  amount held by each,  with such  reduction  to be applied to the
scheduled  principal  payments on the Term Loans due under subsection (c) above,
in the inverse  order of maturity.  Each payment or  prepayment  of a LIBOR Loan
made pursuant to the provisions of this Section 2.5 on a day other than the last
day of the Interest  Period  applicable  thereto shall be made together with all
amounts required under Section 2.13 to be paid as a consequence thereof.

         2.6.         Interest.

         (a) The Borrower  will pay interest in respect of the unpaid  principal
amount of each Loan,  from the date of Borrowing  thereof  until such  principal
amount shall be paid in full,  (i) at the Adjusted  Base Rate, as in effect from
time to time,  during such periods as such Loan is a Base Rate Loan,  or (ii) at
the Adjusted LIBOR Rate, as in effect from time to time,  during such periods as
such Loan is a LIBOR Loan.

         (b) Any  principal  amounts of the Loans not paid when due and,  to the
greatest  extent  permitted by law,  all  interest  accrued on the Loans and all
other  fees and  amounts  hereunder  not paid  when due  (whether  at  maturity,
pursuant to acceleration or otherwise),  shall bear interest at a rate per annum
equal to the Adjusted  Base Rate plus two  percentage  points  (2.0%),  and such
default interest shall be payable on demand. Further, but without duplication of
the foregoing, during the existence of any Event of Default in response to which
the Lenders do not elect to declare  the  outstanding  principal  amounts of the
Loans  immediately  due and payable,  if required by the Required  Lenders,  the
Borrower will pay interest on the dates  provided  pursuant to  subsection  (c),
below, in respect of the unpaid principal amount of each Loan, from the date the
Event of Default  first exists  until it is cured,  at a rate per annum equal to
the Adjusted Base Rate plus two percentage points (2.0%) and such interest shall
be payable on demand.  To the greatest extent  permitted by law,  interest shall
continue to accrue  after the filing by or against the  Borrower of any petition
seeking  any  relief  in  bankruptcy  or  under  any  act or law  pertaining  to
insolvency or debtor relief, whether state, federal or foreign.

         (c)          Accrued (and theretofore unpaid) interest shall be
payable as follows:

                           (i)      in respect of each Base Rate Loan (including
         any Base Rate Loan or portion thereof paid or prepaid pursuant


                                                       -31-

         to the provisions of Section 2.5, except as provided  hereinbelow),  in
         arrears on the last  Business Day of each calendar  quarter,  beginning
         with the first such day to occur after the Closing Date; provided, that
         in the  event the Loans  are  repaid or  prepaid  in full and the Total
         Commitment has been terminated, then accrued interest in respect of all
         Base Rate  Loans  shall be  payable  together  with such  repayment  or
         prepayment on the date thereof;

                          (ii) in  respect of each  LIBOR  Loan  (including  any
         LIBOR  Loan  or  portion  thereof  paid  or  prepaid  pursuant  to  the
         provisions of Section 2.5, except as provided hereinbelow),  in arrears
         (y) on the last Business Day of the Interest Period applicable  thereto
         (subject to the  provisions of clause (iv) in Section  2.8);  provided,
         that in the event all LIBOR Loans made  pursuant to a single  Borrowing
         are repaid or prepaid in full, then accrued interest in respect of such
         LIBOR Loans shall be payable together with such repayment or prepayment
         on the date thereof; and

                         (iii)      in respect of any Loan, at maturity (whether
         pursuant to acceleration or otherwise) and, after maturity, on
         demand.

         (d) Nothing  contained in this  Agreement or in any other Loan Document
shall be deemed to establish or require the payment of interest to any Lender in
an amount in excess of the maximum  amount  permitted by applicable  law. If the
amount of interest or other charges payable for the account of any Lender on any
payment date would exceed the maximum amounts  permitted by applicable law to be
charged by such Lender,  the amount of interest  payable for its account on such
payment date shall be automatically reduced to such maximum permissible amounts.
In the event of any such  reduction  affecting any Lender,  if from time to time
thereafter the amount of interest  payable for the account of such Lender on any
interest  payment  date  would be less than the  maximum  amounts  permitted  by
applicable law to be charged by such Lender, then the amount of interest payable
for its account on such subsequent payment date shall be automatically increased
to such maximum permissible amount, provided that at no time shall the aggregate
amount by which  interest paid for the account of any Lender has been  increased
pursuant to this sentence exceed the aggregate amount by which interest paid for
its account has theretofore been reduced pursuant to the previous sentence.  The
parties hereto  understand and believe that if Maryland law were to apply,  this
lending transaction complies with the usury laws of the State of Maryland. If at
any time, any amount of interest or other charges  actually paid by the Borrower
on or with  respect  to any Loan is  determined  to be in excess of the  maximum
amount  permitted by  applicable  law, such excess amount shall be credited as a
prepayment of the outstanding principal balance of the applicable


                                                       -32-

Loan as of the date paid or, if such Loan has been paid in full, refunded to the
Borrower.

         (e) The Agent shall  promptly  notify the Borrower and the Lenders upon
determining  the  interest  rate for each  Borrowing  of LIBOR  Loans  after its
receipt    of   the    relevant    Notice    of    Borrowing    or   Notice   of
Conversion/Continuation;  provided,  however,  that the  failure of the Agent to
provide the Borrower or the Lenders with any such notice  shall  neither  affect
any  obligations  of the  Borrower  or the Lenders  hereunder  nor result in any
liability  on the part of the Agent to the  Borrower  or any  Lender.  Each such
determination  (including  each  determination  of the  Reserve  Requirement  in
connection  with a Borrowing of LIBOR Loans) shall,  absent  manifest  error, be
final and conclusive and binding on all parties hereto.

         2.7.         Fees.  The Borrower agrees to pay:

         (a) To First Union, for its own account, on the date of this Agreement,
the fees  described in the Fee Letter,  in the amounts set forth  therein as due
and payable on the date of this Agreement and to the extent not theretofore paid
to First Union;

         (b) To the Agent,  for the  account  of each  Lender  with a  Revolving
Credit  Commitment,  a commitment  fee per annum for the period from the date of
this Agreement to the Revolving Credit Facility Termination Date at the rate per
annum as determined  under the following  matrix with  reference to the ratio of
Consolidated  Debt to Adjusted  EBITDA,  applied to the average daily Unutilized
Revolving Credit  Commitment of such Lender,  payable in arrears (i) on the last
Business  Day of each  calendar  quarter,  beginning  with the first such day to
occur  after  the  Closing  Date,  and  (ii) on the  Revolving  Credit  Facility
Termination Date:

         Ratio of Consolidated
         Debt to Adjusted EBITDA                    Fee Percentage

         Greater than 3.0 to 1.0                            0.375%

         Less than or equal to 3.0 to 1.0
         but greater than
           2.5 to 1.0                                       0.30%

         Less than or equal to 2.5 to 1.0                   0.25%

         From the Closing Date until the fifth (5)  Business Day after  delivery
of the  financial  statement  for the fiscal  quarter  ended  September 30, 1996
pursuant to Section 5.1(a) below, the fee percentage shall be .0375%

         (c) To the Agent, for the account of each L/C Participant,  a letter of
credit fee in respect of each  Letter of Credit for the period  from the date of
its  issuance to the date of its  termination,  at a rate per annum equal to the
Applicable Margin for LIBOR

Loans in effect  from time to time  during  such  period,  on the daily  average
Stated Amount  thereof,  payable in arrears (i) on the last Business Day of each
calendar  quarter,  beginning with the first such day to occur after the Closing
Date, and (ii) on the later of the Revolving Credit Facility Termination Date or
the date of termination of the last outstanding Letter of Credit;

         (d) To the Issuing Bank,  for its own account,  a facing fee in respect
of each  Letter of Credit for the period  from the date of its  issuance  to the
date of its  termination,  at the rate of 0.125% per annum, on the daily average
Stated Amount  thereof,  payable in arrears (i) on the last Business Day of each
calendar  quarter,  beginning with the first such day to occur after the Closing
Date, and (ii) on the later of the Revolving  Credit Facility  Termination  Date
and the date of termination of the last outstanding Letter of Credit;

         (e) To the  Issuing  Bank,  for  its  own  account,  such  commissions,
issuance fees,  transfer fees and other fees and charges  incurred in connection
with the issuance and administration of each Letter of Credit as are customarily
charged  from  time to time by the  Issuing  Bank  for the  performance  of such
services in connection  with similar  letters of credit,  or as may be otherwise
agreed to by the  Borrower,  but without  duplication  of amounts  payable under
subsection (d) above; and

         (f) To the Agent, for its own account,  the annual  administrative fees
provided  in the Fee Letter,  on the terms,  in the amounts and at the times set
forth therein.

         2.8.  Interest  Periods.  Concurrently with the giving of any Notice of
Borrowing  or Notice of  Conversion/Continuation  in  respect  of any  Borrowing
comprised of LIBOR Loans,  the Borrower shall have the right to elect,  pursuant
to  such  notice,  the  interest  period  (each,  an  "Interest  Period")  to be
applicable to such LIBOR Loans,  which Interest  Period shall,  at the option of
the Borrower,  be a one, two, or three month period  (subject to  availability);
provided, however, that:

                           (i) all LIBOR Loans comprising a single Borrowing
         shall at all times have the same Interest Period;

                          (ii) the  initial  Interest  Period for any LIBOR Loan
         shall commence on the date of the Borrowing of such Loan (including the
         date of any  continuation of, or conversion into, such LIBOR Loan), and
         each  successive  Interest  Period  applicable to such LIBOR Loan shall
         commence  on the  day on  which  the  next  preceding  Interest  Period
         applicable thereto expires;

                         (iii)      the Borrower may not select any Interest
         Period that begins prior to the Closing Date or that expires after


                                                       -34-

<PAGE>



         (y) the  Revolving  Credit  Facility  Maturity  Date,  with  respect to
         Revolving Credit Loans that are to be maintained as LIBOR Loans, or (z)
         Term Loan Facility  Maturity Date,  with respect to Term Loans that are
         to be maintained as LIBOR Loans;

                          (iv) if any Interest Period  otherwise would expire on
         a day that is not a Business Day, such Interest  Period shall expire on
         the next succeeding  Business Day unless such next succeeding  Business
         Day falls in another calendar month, in which case such Interest Period
         shall expire on the next preceding Business Day;

                           (v) no Interest Period may be selected that would end
         after a scheduled  date for  repayment  of  principal of the Term Loans
         occurring  on or after the first day of such  Interest  Period  unless,
         immediately  after  giving  effect  to such  selection,  the  aggregate
         principal  amount of Term  Loans  that are Base Rate Loans or that have
         Interest  Periods  expiring on or before such principal  repayment date
         equals or exceeds  the  principal  amount  required  to be paid on such
         principal repayment date;

                          (vi) if any Interest  Period begins on a day for which
         there is no numerically  corresponding day in the calendar month during
         which such Interest Period would otherwise expire, such Interest Period
         shall expire on the last Business Day of such calendar month; and

                         (vii) if, upon the  expiration  of any Interest  Period
         applicable  to a Borrowing  of LIBOR  Loans,  the  Borrower  shall have
         failed to elect a new Interest  Period to be  applicable  to such LIBOR
         Loans,  then the  Borrower  shall be deemed to have  elected to convert
         such LIBOR Loans into Base Rate Loans as of the  expiration of the then
         current Interest Period applicable thereto.

         2.9.         Conversions and Continuations.

         (a) The Borrower shall have the right, on any Business Day occurring on
or after the third (3rd)  Business Day after the Closing  Date,  to elect (i) to
convert all or a portion of the  outstanding  principal  amount of any Base Rate
Loans under  either  Facility  into LIBOR Loans under the same  Facility,  or to
convert any LIBOR Loans under either Facility the Interest Periods for which end
on the same  day into  Base  Rate  Loans  under  the same  Facility,  or (ii) to
continue all or a portion of the outstanding principal amount of any LIBOR Loans
under either Facility the Interest  Periods for which end on the same day for an
additional Interest Period, provided that (x) any such conversion of LIBOR Loans
into Base Rate Loans shall  involve an  aggregate  principal  amount of not less
than  $500,000  or, if  greater,  an  integral  multiple  of  $250,000 in excess
thereof; any such conversion of Base Rate Loans


                                                       -35-

into,  or  continuation  of, LIBOR Loans shall  involve an  aggregate  principal
amount of not less than  $5,000,000  or, if  greater,  an  integral  multiple of
$1,000,000  in excess  thereof;  and no partial  conversion  of LIBOR Loans made
pursuant to a single Borrowing shall reduce the outstanding  principal amount of
such  LIBOR  Loans to less  than  $5,000,000  or to any  greater  amount  not an
integral  multiple of  $1,000,000  in excess  thereof,  (y) except as  otherwise
provided in Section  2.11(d),  LIBOR Loans may be converted into Base Rate Loans
only on the last day of the Interest  Period  applicable  thereto  (and,  in any
event,  if a LIBOR Loan is converted into a Base Rate Loan on any day other than
the last day of the Interest Period applicable  thereto,  the Borrower will pay,
upon such  conversion,  all amounts  required under Section 2.13 to be paid as a
consequence  thereof) and (z) no  conversion of Base Rate Loans into LIBOR Loans
or  continuation  of LIBOR Loans shall be permitted  during the continuance of a
Default or Event of Default.

         (b) The  Borrower  shall  make each such  election  by giving the Agent
written  notice not later than 11:00 a.m.,  Charlotte  time,  three (3) Business
Days prior to the effective  date of any  conversion of Base Rate Loans into, or
continuation  of, LIBOR Loans and one (1)  Business  Day prior to the  effective
date of any  conversion  of LIBOR Loans into Base Rate  Loans.  Each such notice
(each, a "Notice of  Conversion/Continuation")  shall be  irrevocable,  shall be
given  in the  form  of  Exhibit  B-2 and  shall  specify  (x) the  date of such
conversion or continuation (which shall be a Business Day), (y) in the case of a
conversion  into, or a continuation  of, LIBOR Loans,  the Interest Period to be
applicable  thereto,  and (z) the  aggregate  amount and Type of the Loans being
converted or continued and the Facility  under which such Loans were made.  Upon
the  receipt of a Notice of  Conversion/Continuation,  the Agent  will  promptly
notify  each  Lender  having a  Commitment  under the  relevant  Facility of the
proposed  conversion or continuation.  In the event that the Borrower shall fail
to deliver a Notice of Conversion/  Continuation as provided herein with respect
to any  outstanding  LIBOR  Loans,  such  LIBOR  Loans  shall  automatically  be
converted to Base Rate Loans upon the  expiration  of the then current  Interest
Period applicable thereto (unless repaid pursuant to the terms hereof).

         2.10.        Method of Payments; Computations.

         (a) All  payments  by the  Borrower  hereunder  shall  be made  without
setoff,  counterclaim or other defense, in Dollars and in immediately  available
funds  to the  Agent,  for the  account  of the  Lenders  (except  as  otherwise
expressly  provided  herein as to payments  required to be made  directly to the
Issuing Bank and the Lenders) at its office  referred to in Section 10.4,  prior
to 12:00 noon,  Charlotte  time, on the date payment is due. Any payment made as
required  hereinabove,  but after 12:00 noon, Charlotte time, shall be deemed to
have been made on the next succeeding  Business Day. If any payment falls due on
a day that is not a Business Day,


                                                       -36-

<PAGE>



then such due date shall be extended to the next succeeding Business Day (except
that in the  case of LIBOR  Loans to which  the  provisions  of  clause  (iv) in
Section 2.8 are applicable,  such due date shall be the next preceding  Business
Day),  and such  extension of time shall then be included in the  computation of
payment of interest, fees or other applicable amounts.

         (b) The Agent will  distribute to the Lenders like amounts  relating to
payments made to the Agent for the account of the Lenders as follows: (i) if the
payment is received by 12:00 noon,  Charlotte  time,  in  immediately  available
funds,  the Agent will make available to each relevant  Lender on the same date,
by wire transfer of immediately  available funds, such Lender's ratable share of
such payment  (based on the percentage  that the amount of the relevant  payment
owing to such Lender bears to the total  amount of such payment  owing to all of
the relevant  Lenders),  and (ii) if such payment is received  after 12:00 noon,
Charlotte time, or in other than  immediately  available  funds,  the Agent will
make  available  to each such Lender its ratable  share of such  payment by wire
transfer of immediately  available funds on the next succeeding Business Day (or
in the case of uncollected  funds, as soon as practicable after  collected).  If
the Agent shall not have made a required distribution to the appropriate Lenders
as  required  hereinabove  after  receiving  a payment  for the  account of such
Lenders, the Agent will pay to each such Lender, on demand, its ratable share of
such payment with  interest  thereon at the Federal Funds Rate for each day from
the date such amount was  required to be  disbursed  by the Agent until the date
repaid to such  Lender.  The Agent  will  distribute  to the  Issuing  Bank like
amounts  relating to  payments  made to the Agent for the account of the Issuing
Bank in the same manner,  and subject to the same terms and  conditions,  as set
forth hereinabove with respect to distributions of amounts to the Lenders.

         (c)  Unless the Agent  shall  have  received  written  notice  from the
Borrower  prior to the date on which any payment is due to any Lender  hereunder
that  such  payment  will not be made in full,  the Agent  may  assume  that the
Borrower has made such payment in full to the Agent on such date,  and the Agent
may, in reliance on such assumption,  but shall not be obligated to, cause to be
distributed  to such Lender on such due date an amount  equal to the amount then
due to such  Lender.  If and to the extent the  Borrower  shall not have so made
such payment in full to the Agent,  and without  limiting the  obligation of the
Borrower to make such payment in accordance  with the terms hereof,  such Lender
shall repay to the Agent  forthwith on demand such amount so distributed to such
Lender, together with interest thereon for each day from the date such amount is
so distributed to such Lender until the date repaid to the Agent, at the Federal
Funds Rate.

         (d) Each Lender for whose  account any payment is to be made  hereunder
may,  but shall not be  obligated  to,  debit the amount of any such payment not
made as and when required hereunder to any


                                                       -37-

<PAGE>



ordinary deposit account of the Borrower with such Lender (with prompt notice to
the Agent and the Borrower);  provided,  however,  that the failure to give such
notice shall not affect the validity of such debit by such Lender.

         (e) With  respect to each  payment  hereunder,  except as  specifically
provided  otherwise  herein or in any of the other Loan Documents,  the Borrower
may designate by written notice to the Agent prior to or concurrently  with such
payment the Types of Loans that are to be paid, repaid or prepaid, provided that
(i) unless made together with all amounts required under Section 2.13 to be paid
as a consequence  thereof,  a prepayment of a LIBOR Loan may be made only on the
last day of the Interest  Period  applicable  thereto,  and (ii) each payment on
account of any  Obligations  to or for the  account  of any one or more  Lenders
shall be apportioned  ratably among such Lenders in proportion to the amounts of
such  Obligations  owed  to  them  respectively.  In the  absence  of  any  such
designation  by the  Borrower,  or if an Event of Default  has  occurred  and is
continuing,  the Agent shall make such  designation in its sole discretion or as
the  Required  Lenders may  direct,  subject to the  foregoing  and to the other
provisions of this Agreement.

         (f)  All  computations  of  interest  and  fees  hereunder   (including
computations  of the Reserve  Requirement)  shall be made on the basis of a year
consisting of 360 days and the actual number of days  (including  the first day,
but excluding the last day) elapsed;  provided,  however,  that interest on Base
Rate Loans shall be computed on the basis of a  365/366-day  year and the actual
days elapsed.

         2.11.        Increased Costs, Change in Circumstances, Etc.

         (a) If, at any time after the Closing  Date and from time to time,  the
adoption or  modification  of any  applicable  law, rule or  regulation,  or any
interpretation  or  administration  thereof  by any  Governmental  Authority  or
central  bank  (whether  or not  having  the  force  of law)  charged  with  the
interpretation,  administration  or  compliance  of the Lenders with any of such
requirements, shall:

                           (i) subject any Lender to, or increase the net amount
         of, any tax,  impost,  duty,  charge or withholding with respect to any
         amount  received or to be received  hereunder in connection  with LIBOR
         Loans  (other  than taxes  imposed on net income or profits  of, or any
         branch or franchise tax  applicable to, such Lender or a Lending Office
         of such Lender);

                          (ii)  change the basis of  taxation of payments to any
         Lender in  connection  with LIBOR Loans (other than changes in taxes on
         the net income or profits of, or any branch or franchise tax applicable
         to, such Lender or a Lending Office of such Lender);


                                                       -38-

<PAGE>




                         (iii) impose, increase or render applicable any reserve
         (other than the Reserve Requirement), capital adequacy, special deposit
         or similar  requirement  against  assets of,  deposits  with or for the
         account of, or loans, credit or commitments  extended by, any Lender or
         a Lending Office of such Lender; or

                         (iv)  impose on any Lender or in the London interbank
         Eurodollar market any other condition or requirement affecting this
         Agreement or LIBOR Loans;

and the result of any of the foregoing is to increase the costs to any Lender of
agreeing to make,  making,  funding or maintaining  any LIBOR Loans or to reduce
the yield or rate of return of such  Lender on any LIBOR  Loans to a level below
that which such Lender could have achieved but for the adoption or  modification
of any such  requirements,  the Borrower  will,  within  fifteen (15) days after
delivery to the Borrower by such Lender of written demand  therefor (with a copy
thereof to the Agent),  pay to such Lender such additional  amounts  relating or
directly  corresponding  to the Loans as shall  compensate  such Lender for such
increase in costs or reduction in return.

         (b) If, at any time after the Closing  Date and from time to time,  the
adoption or modification of any applicable federal,  state or local law, rule or
regulation  regarding  any Lender's  required  level of capital  (including  any
allocation of capital requirements or conditions,  but excluding federal,  state
or local income tax liability),  or the  implementation of any such requirements
previously  adopted  but not  implemented  prior  to the  Closing  Date,  or any
interpretation or administration  thereof by any Governmental Authority (whether
or not having the force of law) charged with the interpretation,  administration
or  compliance of such Lender with any of such  requirements,  has or would have
the  effect  of  reducing  the rate of  return  on such  Lender's  capital  as a
consequence of its  Commitments,  Loans or  participations  in Letters of Credit
hereunder  to a level below that which such Lender  could have  achieved but for
such  adoption,  modification,  implementation  or  interpretation  (taking into
account such Lender's policies with respect to capital  adequacy),  the Borrower
will,  within fifteen (15) days after delivery to the Borrower by such Lender of
written demand  therefor (with a copy thereof to the Agent),  pay to such Lender
such  additional  amounts as will  compensate  such Lender for such reduction in
return.

         (c) If, on or prior to the first day of any  Interest  Period,  (i) the
Agent shall have  determined  that Dollar deposits in the amount of any Lender's
required  LIBOR Loan pursuant to such  Borrowing are not generally  available in
the London  interbank  Eurodollar  market or that the rate at which such  Dollar
deposits are being offered will not  adequately  and fairly  reflect the cost to
such Lender of making or maintaining  its LIBOR Loan during such Interest Period
or (ii) the Agent shall have determined that


                                                       -39-

<PAGE>



adequate and reasonable means do not exist for ascertaining the applicable LIBOR
Rate for such Interest  Period,  the Agent will forthwith so notify the Borrower
and the  Lenders,  whereupon  the  obligation  of (y) in the case of clause  (i)
above, each such affected Lender,  and (z) in the case of clause (ii) above, all
Lenders,  in each case to make, to convert Base Rate Loans into, or to continue,
LIBOR Loans shall be  suspended  (including  pursuant to the  Borrowing to which
such  Interest  Period  applies),  and any  Notice  of  Borrowing  or  Notice of
Conversion/Continuation given at any time thereafter with respect to LIBOR Loans
shall be deemed to be a request  for Base Rate  Loans (but in the case of clause
(i) above,  only to the extent of such affected Lender's Pro Rata Share thereof)
until  the  Agent  or the  affected  Lender,  as the  case  may be,  shall  have
determined that the circumstances giving rise to such suspension no longer exist
(and the affected Lender, if making such  determination,  shall have so notified
the Agent), and the Agent shall have so notified the Borrower and the Lenders.

         (d) Notwithstanding  any other provision in this Agreement,  if, at any
time after the Closing Date and from time to time, the adoption or  modification
of  any  applicable  law,  rule  or  regulation,   or  any   interpretation   or
administration thereof by any Governmental Authority or central bank (whether or
not having the force of law) charged with the interpretation,  administration or
compliance  of any Lender with any of such  requirements,  has or would have the
effect of making it  unlawful  for such Lender to honor its  obligation  to make
LIBOR Loans or to continue to make or  maintain  LIBOR  Loans,  such Lender will
forthwith  so  notify  the Agent and the  Borrower,  whereupon  (i) each of such
Lender's outstanding LIBOR Loans shall automatically,  on the expiration date of
the respective  Interest  Period  applicable  thereto or, to the extent any such
LIBOR Loan may not lawfully be maintained as a LIBOR Loan until such  expiration
date,  upon  such  notice,  be  converted  into a Base  Rate  Loan  and (ii) the
obligation  of such  Lender to make,  to  convert  Base Rate Loans  into,  or to
continue,  LIBOR Loans shall be suspended, and any Notice of Borrowing or Notice
of  Conversion/Continuation  given at any time  thereafter with respect to LIBOR
Loans shall,  as to such Lender,  be deemed to be a request for Base Rate Loans,
until such Lender shall have  determined that the  circumstances  giving rise to
such  suspension  no longer exist and shall have so notified the Agent,  and the
Agent shall have so notified the Borrower.

         (e)  Determinations  by the Agent or any  Lender for  purposes  of this
Section of any  increased  costs,  reduction  in return,  market  contingencies,
illegality or any other matter shall,  absent  manifest  error,  be  conclusive,
provided  that such  determinations  are made in good faith.  Each Lender agrees
that,  upon the  occurrence  of any event  giving rise to the  operation of this
Section with respect to such Lender,  it will,  if requested by the Borrower and
to the extent  permitted  by law,  endeavor in good faith to  designate  another
Lending Office for its LIBOR Loans, but only if such


                                                       -40-

<PAGE>



designation would make it lawful for such Lender to continue to make or maintain
LIBOR Loans hereunder; provided that such designation is made on such terms that
such  Lender,  in its good faith  determination,  suffers no  increased  cost or
economic,  legal or  regulatory  disadvantage,  with the object of avoiding  the
consequence of the event giving rise to the operation of this Section.

         (f) Each demand for payment  under this Section  shall be preceded by a
notice to the Borrower of such anticipated demand, which notice shall specify in
reasonable  detail the basis for such  demand,  but the failure to provide  such
advance  notice  shall  not  relieve  the  Borrower  of any  of its  obligations
hereunder.  No  failure  by the Agent or any  Lender to  demand  payment  of any
amounts  payable  under this Section  shall  constitute a waiver of its right to
demand payment of any additional amounts arising at any subsequent time. Nothing
in this  Section  shall be construed or so operate as to require the Borrower to
pay any  interest,  fees,  costs or  charges  in  excess  of that  permitted  by
applicable law.

         2.12.        Taxes.

         (a) Any and all  payments by the  Borrower  hereunder or under any Note
shall be made, in accordance  with the terms hereof and thereof,  free and clear
of and  without  deduction  for any and all  present  or future  taxes,  levies,
imposts, deductions,  charges or withholdings,  and all liabilities with respect
thereto  (other than taxes imposed on net income or profits of, or any branch or
franchise taxes applicable to, the Agent, the Issuing Bank or any Lender) (y) by
the  jurisdiction  under the laws of which the Agent,  the Issuing  Bank or such
Lender,  as the case may be, is organized or any political  subdivision  thereof
and (z) in the case of each  Lender,  by the  jurisdiction  in which any Lending
Office of such Lender is located or any political  subdivision thereof (all such
non-excluded  taxes,  levies,  imposts,  deductions,  charges,  withholdings and
liabilities being hereinafter referred to as "Taxes").  If the Borrower shall be
required  by law to  deduct  any Taxes  from or in  respect  of any sum  payable
hereunder or under any Note to the Agent,  the Issuing  Bank or any Lender,  (i)
the sum payable  shall be increased as may be necessary so that after making all
required deductions  (including deductions applicable to additional sums payable
under this Section), the Agent, the Issuing Bank or such Lender, as the case may
be,  receives  an amount  equal to the sum it would  have  received  had no such
deductions been made, (ii) the Borrower will make such deductions, and (iii) the
Borrower will pay the full amount deducted to the relevant taxation authority or
other authority in accordance with applicable law. If and to the extent that any
Lender  subsequently  shall be refunded or otherwise  recover all or any part of
such deduction, it shall refund to the Borrower the amount so recovered.



                                                       -41-

<PAGE>



         (b) The Borrower will  indemnify  the Agent,  the Issuing Bank and each
Lender for the full amount of Taxes (including,  without  limitation,  any Taxes
imposed by any  jurisdiction  on amounts payable under this Section) paid by the
Agent,  the Issuing Bank or such Lender,  as the case may be, and any  liability
(including  penalties,  interest and expenses) arising therefrom or with respect
thereto.  This  indemnification  shall be made  within 30 days from the date the
Agent, the Issuing Bank or any Lender,  as the case may be, makes written demand
therefor.  Within  thirty  (30)  days  after  the date of any  payment  of Taxes
pursuant to this Section,  the Borrower  will furnish to the Agent,  the Issuing
Bank or the  relevant  Lender,  as the case may be, the  original or a certified
copy of a receipt  evidencing  payment  thereof.  If and to the extent  that any
Lender  subsequently  shall be refunded or otherwise  recover all or any part of
such payment of taxes, it shall refund to the Borrower the amount so recovered.

         (c) If any  Lender is a  "foreign  corporation,  partnership  or trust"
within  the  meaning  of the  Internal  Revenue  Code,  and such  Lender  claims
exemption from United States  withholding  tax under Section 1441 or 1442 of the
Internal Revenue Code, such Lender will deliver to the Agent and the Borrower:

                           (i) if such Lender  claims an  exemption  from,  or a
         reduction  of,  withholding  tax  under a  United  States  tax  treaty,
         properly  completed  IRS Forms 1001 and W-8  before the  payment of any
         interest  in the first  calendar  year,  and before the  payment of any
         interest in each third succeeding  calendar year, during which interest
         may be paid to such Lender under this Agreement;

                          (ii) if such Lender  claims that  interest  paid under
         this Agreement is exempt from United States  withholding tax because it
         is effectively connected with a United States trade or business of such
         Lender,  two properly  completed  and executed  copies of IRS Form 4224
         before the payment of any interest is due in the first  taxable year of
         such Lender, and in each succeeding taxable year of such Lender, during
         which interest may be paid to such Lender under this Agreement, and IRS
         Form W-9; and

                         (iii) such other form or forms as may be required under
         the  Internal  Revenue  Code or other  laws of the  United  States as a
         condition to exemption from, or reduction of, United States withholding
         tax.

         Each such Lender will promptly notify the Agent and the Borrower of any
changes  in  circumstances  that  would  modify or render  invalid  any  claimed
exemption or reduction.

         (d)          If any Lender is entitled to a reduction in the applicable
withholding tax, the Agent may withhold from any interest payment to such Lender
an amount equivalent to the


                                                       -42-

<PAGE>



applicable  withholding  tax after taking into account  such  reduction.  If the
forms or  other  documentation  required  under  subsection  (c)  above  are not
delivered to the Agent, then the Agent may withhold from any interest payment to
such Lender not providing such forms or other documentation an amount equivalent
to the applicable  withholding tax. For purposes of this Section, a distribution
hereunder  by the Agent to or for the  account of any  Lender  shall be deemed a
payment by the Borrower.

         (e)  If the  IRS  or any  other  Governmental  Authority,  domestic  or
foreign,  asserts  a claim  that the Agent did not  properly  withhold  tax from
amounts  paid  to or  for  the  account  of  any  Lender  (whether  because  the
appropriate  form was not delivered or was not properly  executed,  because such
Lender failed to notify the Agent of a change in circumstances that rendered the
exemption from, or reduction of,  withholding tax ineffective,  or for any other
reason),  such Lender  shall  indemnify  the Agent  fully for all amounts  paid,
directly or indirectly,  by the Agent as tax or otherwise,  including  penalties
and interest, and including any taxes imposed by any jurisdiction on the amounts
payable  to the Agent  under  this  subsection  (e),  together  with all  costs,
expenses  and  reasonable   attorneys'  fees  incurred  or  paid  in  connection
therewith.

         (f) If at any time the  Borrower  requests  any Lender to  deliver  any
forms or other documentation pursuant to subsection (c) above, then the Borrower
shall,  upon demand of such  Lender,  reimburse  such Lender for any  reasonable
costs or expenses incurred by such Lender in the preparation or delivery of such
forms or other documentation.

         (g) Each  Lender  agrees  that,  if the  Borrower  is  required  to pay
additional  amounts to or for the account of any Lender  pursuant to  subsection
(a) or (b)  above,  then such  Lender  will,  to the  extent  permitted  by law,
endeavor in good faith to designate  another Lending Office for its LIBOR Loans,
but only if such designation would make it lawful for such Lender to continue to
make or maintain LIBOR Loans  hereunder;  provided that such designation is made
on such terms that such  Lender,  in its good  faith  determination,  suffers no
increased cost or economic, legal or regulatory disadvantage, with the object of
avoiding  the  consequence  of the event  giving rise to the  operation  of this
Section.

         2.13.  Compensation.  The  Borrower  will  compensate  each Lender upon
demand for all losses, expenses and liabilities (including,  without limitation,
any  loss,  expense  or  liability  incurred  by reason  of the  liquidation  or
reemployment  of  deposits  or other  funds  required  by such Lender to fund or
maintain  LIBOR Loans) that such Lender may sustain (i) if for any reason (other
than a default by such Lender) a Borrowing of, or  conversion of or into,  LIBOR
Loans does not occur on a date specified therefor in a Notice of


                                                       -43-

<PAGE>



Borrowing  or  Notice  of   Conversion/Continuation,   (ii)  if  any  repayment,
prepayment  or conversion of any LIBOR Loan occurs on a date other than the last
day of an Interest  Period  applicable  thereto  (including as a consequence  of
acceleration  of the maturity of such Loans  pursuant to Section 8.1),  (iii) if
any  prepayment of any of its LIBOR Loans is not made on any date specified in a
notice of  prepayment  given by the Borrower,  or (iv) as a  consequence  of any
other  failure by the Borrower to make any payments  with respect to LIBOR Loans
when due hereunder. In addition, the Borrower will pay to the Agent, for its own
account,  an  administrative  fee of $100 concurrently with any payments made in
respect of any single  occurrence  pursuant to this Section.  Calculation of all
amounts  payable to a Lender  under this  Section  shall be made as though  such
Lender had  actually  funded its  relevant  LIBOR Loan through the purchase of a
Eurodollar  deposit bearing interest at the LIBOR Rate in an amount equal to the
amount of such LIBOR Loan, having a maturity comparable to the relevant Interest
Period and through  the  transfer of such  Eurodollar  deposit  from an offshore
Lending  Office of such Lender to a Lending  Office of such Lender in the United
States; provided,  however, that each Lender may fund each of its LIBOR Loans in
any manner it sees fit and the foregoing  assumption  shall be utilized only for
the  calculation of amounts  payable under this Section.  Determinations  by any
Lender for purposes of this Section of any such losses,  expenses or liabilities
shall,  absent manifest error, be conclusive,  provided that such determinations
are made in good faith.

         2.14. Use of Proceeds. The proceeds of the Term Loans and the Revolving
Credit Loans shall be used by the Borrower (i) to finance Permitted Acquisitions
pursuant to this Agreement; (ii) to provide working capital for the Borrower and
its Subsidiaries; and (iii) for general corporate purposes.

         2.15.        Recovery of Payments.

         (a) The Borrower agrees that to the extent the Borrower makes a payment
or payments to or for the account of the Agent, the Lenders or the Issuing Bank,
which  payment or payments or any part  thereof  are  subsequently  invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee,  receiver  or any other  party under any  bankruptcy,  insolvency  or
similar state or federal law, common law or equitable cause, then, to the extent
of such payment or  repayment,  the Credit  Obligation  intended to be satisfied
shall be revived and  continued  in full force and effect as if such payment had
not been received.

         (b)  If  any  amounts   distributed  by  the  Agent  to  a  Lender  are
subsequently   returned  or  repaid  by  the  Agent  to  the   Borrower  or  its
representative or successor in interest, whether by court order or by settlement
approved by the Lender in question,  such Lender will,  promptly upon receipt of
notice  thereof from the Agent,  pay the Agent such amount.  If any such amounts
are recovered by the Agent


                                                       -44-

from the Borrower or its  representative  or  successor  in interest,  the Agent
shall redistribute such amounts to the Lenders on the same basis as such amounts
were originally distributed.

         2.16.        Pro Rata Treatment.

         (a) All funding of Borrowings,  continuations  and conversions of Loans
shall be made by the Lenders pro rata on the basis of their relative Commitments
(in the case of the  funding  of the  Term  Loans  and the  initial  funding  of
Revolving  Loans)  or Loans (in the case of  continuations  and  conversions  of
Loans), as applicable from time to time.

         (b) Each Lender  agrees that if it shall  receive any amount  hereunder
(whether by voluntary payment,  realization upon security, exercise of the right
of  setoff  or  banker's  lien,  counterclaim  or cross  action,  or  otherwise,
applicable  to the  payment of any of the Credit  Obligations  that  exceeds its
ratable  share  (according  to the  proportion  of (i) the amount of such Credit
Obligations  due and payable to such  Lender at such time to (ii) the  aggregate
amount of such Credit  Obligations  due and payable to all Lenders at such time)
of payments on account of such Credit  Obligations then or therewith obtained by
all the Lenders to which such  payments  are  required  to have been made,  such
Lender shall forthwith  purchase from the other Lenders such  participations  in
such Credit Obligations as shall be necessary to cause such purchasing Lender to
share the excess payment or other recovery ratably with each of them;  provided,
however,  that  if all or any  portion  of such  excess  payment  is  thereafter
recovered from such purchasing Lender, such purchase from each such other Lender
shall be  rescinded  and each such other  Lender  shall repay to the  purchasing
Lender the  purchase  price to the  extent of such  recovery,  together  with an
amount equal to such other Lender's  ratable share  (according to the proportion
of (i) the amount of such other  Lender's  required  repayment to (ii) the total
amount so recovered from the purchasing  Lender) of any interest or other amount
paid or payable  by the  purchasing  Lender in  respect  of the total  amount so
recovered.  The Borrower  agrees that any Lender so  purchasing a  participation
from another Lender  pursuant to the provisions of this  subsection  may, to the
fullest  extent  permitted  by  law,  exercise  any and all  rights  of  payment
(including,  without  limitation,  setoff,  banker's lien or counterclaim)  with
respect  to such  participation  as fully as if such  participant  were a direct
creditor  of the  Borrower  in the  amount of such  participation.  If under any
applicable bankruptcy,  insolvency or similar law, any Lender receives a secured
claim in lieu of a setoff to which this subsection  applies,  such Lender shall,
to the extent practicable,  exercise its rights in respect of such secured claim
in a manner  consistent  with the  rights of the  Lenders  entitled  under  this
subsection to share in the benefits of any recovery on such secured claim.

         2.17.        Letters of Credit.

         (a) Subject to and upon the terms and conditions  herein set forth,  so
long as no Default or Event of  Default  has  occurred  and is  continuing,  the
Issuing  Bank will,  at any time and from time to time on and after the  Closing
Date and prior to the  Revolving  Credit  Facility  Termination  Date,  and upon
request by the Borrower in accordance  with the  provisions of Section  2.17(b),
issue for the account of the Borrower one or more irrevocable standby letters of
credit  denominated  in  Dollars  and in a form  customarily  used or  otherwise
approved by the Issuing Bank (together with all  amendments,  modifications  and
supplements  thereto,  substitutions  therefor  and  renewals  and  restatements
thereof,  collectively,  the  "Letters of  Credit").  The Stated  Amount of each
Letter of  Credit  shall  not be less  than  such  amount  as may be  reasonably
acceptable to the Issuing Bank. Notwithstanding the foregoing:

                           (i) No Letter of Credit  shall be issued  the  Stated
         Amount  upon  issuance  of which (i) when added to all other  Letter of
         Credit  Outstandings at such time, would exceed $5,000,000 or (ii) when
         added to all other Letter of Credit  Outstandings  at such time and the
         aggregate   principal   amount  of  all  Revolving  Credit  Loans  then
         outstanding, would exceed the Total Revolving Credit Commitment at such
         time;

                          (ii) No Letter of Credit  shall be issued  that by its
         terms  expires more than one (1) year after its date of issuance or the
         Revolving  Credit  Facility  Maturity  Date,   whichever  is  earliest;
         provided,  however,  that a Letter of Credit may, if  requested  by the
         Borrower and approved by the Issuing Bank, provide by its terms, and on
         terms  acceptable  to the Issuing  Bank,  for  renewal  for  successive
         periods of one year or less,  unless and until the  Issuing  Bank shall
         have delivered a notice of nonrenewal to the beneficiary of such Letter
         of Credit; and

                         (iii) The Issuing Bank shall be under no  obligation to
         issue any Letter of Credit if, at the time of such  proposed  issuance,
         (A) any order,  judgment  or decree of any  Governmental  Authority  or
         arbitrator shall purport by its terms to enjoin or restrain the Issuing
         Bank from  issuing  such Letter of Credit,  or any  Requirement  of Law
         applicable to the Issuing Bank or any request or directive  (whether or
         not  having  the force of law)  from any  Governmental  Authority  with
         jurisdiction over the Issuing Bank shall prohibit,  or request that the
         Issuing Bank refrain from, the issuance of letters of credit  generally
         or such Letter of Credit in particular or shall impose upon the Issuing
         Bank with respect to such Letter of Credit any  restriction  or reserve
         or capital  requirement  (for which the Issuing  Bank is not  otherwise
         compensated)  not in effect on the Closing  Date,  or any  unreimbursed
         loss,  cost or expense that was not  applicable,  in effect or known to
         the


                                                       -46-

<PAGE>



         Issuing  Bank as of the Closing  Date and that the Issuing Bank in good
         faith deems  material to it, or (B) the Issuing  Bank shall have actual
         knowledge,  or shall have received notice from any Lender, prior to the
         issuance of such  Letter of Credit  that one or more of the  conditions
         specified in Section 3.3 are not then satisfied or that the issuance of
         such Letter of Credit would violate the  provisions  of subsection  (i)
         above.

         (b) Whenever  the Borrower  desires the issuance of a Letter of Credit,
the Borrower will notify the Issuing Bank (with copies to the Agent) in writing,
by 1:00 p.m., Charlotte,  North Carolina local time, at least three (3) Business
Days (or such shorter  period as is  acceptable to the Issuing Bank in any given
case) prior to the requested date of issuance thereof.  Each such request (each,
a "Letter of Credit  Request") shall be irrevocable,  shall be given in the form
of Exhibit B-3 and shall be appropriately  completed to specify (i) the proposed
date of issuance  (which  shall be a Business  Day),  (ii) the  proposed  Stated
Amount and expiry  date of the Letter of Credit,  and (iii) the name and address
of the  proposed  beneficiary  or  beneficiaries  of the Letter of  Credit.  The
Borrower will also complete any application  procedures and documents reasonably
required by the Issuing  Bank in  connection  with the issuance of any Letter of
Credit. The Agent will, promptly upon its receipt thereof, notify each Lender of
the Letter of Credit  Request.  Upon its  issuance of any Letter of Credit,  the
Issuing Bank will  promptly  notify each Lender of such issuance and will notify
each  Lender  with  a  Revolving   Credit   Commitment  of  the  amount  of  its
participation therein under Section 2.17(c).

         (c) Immediately upon the issuance of any Letter of Credit,  the Issuing
Bank  shall  be  deemed  to have  sold and  transferred  to each  Lender  with a
Revolving Credit  Commitment,  and each such Lender (each, in such capacity,  an
"L/C  Participant")  shall be deemed  irrevocably  and  unconditionally  to have
purchased and received from the Issuing Bank,  without recourse or warranty,  an
undivided  interest and  participation,  pro rata to the extent of its Revolving
Credit  Percentage  at such time,  in such Letter of Credit,  each  drawing made
thereunder,  and the  obligations  of the  Borrower  under this  Agreement  with
respect thereto and any security therefor (including the Collateral) or guaranty
pertaining thereto; provided,  however, that the fees and other charges relating
to  Letters  of Credit  described  in  Sections  2.7(d) and (e) shall be payable
directly to the Issuing Bank as provided therein, and the L/C Participants shall
have no right to receive any portion  thereof.  Upon any change in the Revolving
Credit  Commitments of any of the Lenders pursuant to Section 10.5, with respect
to all outstanding  Letters of Credit and Reimbursement  Obligations there shall
be an automatic  adjustment  to the  participations  pursuant to this Section to
reflect the new Revolving  Credit  Percentages  of the assigning  Lender and the
Eligible Assignee.

         (d) The Borrower  hereby agrees to reimburse the Issuing Bank by making
payment to the  Agent,  for the  account of the  Issuing  Bank,  in  immediately
available  funds,  for any payment  made by the Issuing Bank under any Letter of
Credit  (each  such  amount so paid until  reimbursed,  together  with  interest
thereon  payable  as  provided   hereinbelow,   a  "Reimbursement   Obligation")
immediately after, and in any event on the date of, such payment,  together with
interest on the amount so paid by the Issuing Bank, to the extent not reimbursed
prior to 2:00 p.m.,  Charlotte,  North  Carolina local time, on the date of such
payment  or  disbursement,  (i) for the period  from the date of the  respective
payment to the date of receipt by the  Borrower  from the Issuing Bank of notice
of such payment, at the Adjusted Base Rate as in effect from time to time during
such  period,  and (ii) for the period from the date of receipt by the  Borrower
from the Issuing  Bank of notice of such  payment to the date the  Reimbursement
Obligation created thereby is satisfied,  at the Adjusted Base Rate as in effect
from time to time during such period plus two  percentage  points  (2.0%),  such
interest  also to be payable on demand.  The Issuing Bank will provide the Agent
and the Borrower  with prompt notice of any payment or  disbursement  made under
any Letter of Credit,  although the failure to give, or any delay in giving, any
such notice  shall not  release,  diminish or  otherwise  affect the  Borrower's
obligations under this Section or any other provision of this Agreement.

         (e) In the event  that the  Issuing  Bank makes any  payment  under any
Letter of Credit and the  Borrower  shall not have timely  satisfied in full its
Reimbursement Obligation to the Issuing Bank pursuant to Section 2.17(d), and to
the extent that any amounts then held in the Cash Collateral Account established
pursuant to Section 2.17(i) shall be insufficient to satisfy such  Reimbursement
Obligation  in full,  the Issuing Bank will promptly  notify the Agent,  and the
Agent will promptly notify each L/C Participant,  of such failure.  If the Agent
gives such notice prior to 11:00 a.m., Charlotte,  North Carolina local time, on
any  Business  Day to any  L/C  Participant,  such  L/C  Participant  will  make
available to the Agent,  for the account of the Issuing Bank, its Pro Rata Share
(calculated  with respect to its Revolving  Credit  Percentage) of the amount of
such payment on such Business Day in immediately  available  funds. If the Agent
gives such notice after 11:00 a.m., Charlotte, North Carolina local time, on any
Business Day to any such L/C  Participant,  such L/C Participant  shall make its
Pro Rata  Share of such  amount  available  to the Agent on the next  succeeding
Business Day. If and to the extent such L/C  Participant  shall not have so made
its Pro Rata Share of the amount of such payment  available  to the Agent,  such
L/C Participant agrees to pay to the Agent, for the account of the Issuing Bank,
forthwith on demand such amount,  together with interest  thereon,  for each day
from such date until the date such  amount is paid to the Agent,  at the Federal
Funds Rate.  The failure of any L/C  Participant  to make available to the Agent
its Pro Rata Share of any payment  under any Letter of Credit  shall not relieve
any other L/C  Participant of its obligation  hereunder to make available to the
Agent its Pro Rata


                                                       -48-

<PAGE>



Share of any  payment  under  any  Letter of  Credit  on the date  required,  as
specified above, but no L/C Participant  shall be responsible for the failure of
any  other  L/C  Participant  to make  available  to the  Agent  such  other L/C
Participant's  Pro Rata Share of any such  payment.  Each such payment by an L/C
Participant  under this Section  2.17(e) of its Pro Rata Share of an amount paid
by the Issuing Bank shall constitute a Revolving Credit Loan by such Lender (the
Borrower  being deemed to have given a timely Notice of Borrowing  therefor) and
shall be treated as such for all purposes of this  Agreement;  provided that for
purposes of  determining  the available  unused  portion of the Total  Revolving
Credit  Commitment  immediately prior to giving effect to the application of the
proceeds of such Revolving  Credit Loans,  the  Reimbursement  Obligation  being
satisfied thereby shall be deemed not to be outstanding at such time.

         (f)  Whenever  the  Issuing  Bank  receives  a payment  in respect of a
Reimbursement  Obligation as to which the Agent has received, for the account of
the Issuing  Bank,  any payments from the L/C  Participants  pursuant to Section
2.17(e),  the Issuing Bank will  promptly  pay to the Agent,  and the Agent will
promptly pay to each L/C  Participant  that has paid its Pro Rata Share thereof,
in  immediately  available  funds,  an  amount  equal to such L/C  Participant's
ratable share (based on the proportionate  amount funded by such L/C Participant
to the aggregate amount funded by all L/C  Participants)  of such  Reimbursement
Obligation.

         (g) The Reimbursement  Obligations of the Borrower, and the obligations
of the L/C  Participants  to make payments to the Agent,  for the account of the
Issuing Bank,  with respect to Letters of Credit,  shall be  irrevocable,  shall
remain in effect  until the Issuing  Bank shall have no further  obligations  to
make any payments or disbursements  under any circumstances  with respect to any
Letter of Credit,  and, except to the extent resulting from any gross negligence
or willful misconduct on the part of the Issuing Bank as finally determined by a
court of  competent  jurisdiction  and not subject to any appeal (or pursuant to
arbitration  as  set  forth  in  Section  10.3(b)),  shall  not  be  subject  to
counterclaim,  setoff or other defense or any other  qualification  or exception
whatsoever and shall be made in accordance with the terms and conditions of this
Agreement under all circumstances,  including,  without  limitation,  any of the
following circumstances:

                           (i)  Any lack of validity or enforceability of this
         Agreement, any of the other Loan Documents or any documents or
         instruments relating to any Letter of Credit;

                          (ii)  Any  change  in the  time,  manner  or  place of
         payment  of,  or in any  other  term  of,  all  or  any  of the  Credit
         Obligations  in respect  of any  Letter of  Credit,  whether or not the
         Borrower has notice or knowledge thereof;



                                                       -49-

<PAGE>



                         (iii) The  existence of any claim,  setoff,  defense or
         other  right  that  the  Borrower  may  have  at  any  time  against  a
         beneficiary  named in a Letter of Credit,  any transferee of any Letter
         of Credit (or any Person for whom any such  transferee  may be acting),
         the Agent,  the Issuing Bank,  any Lender or other  Person,  whether in
         connection with this Agreement,  any Letter of Credit, the transactions
         contemplated  hereby  or  any  unrelated  transactions  (including  any
         underlying  transaction  between the Borrower and the beneficiary named
         in any such Letter of Credit);

                          (iv) Any  draft,  certificate  or any  other  document
         presented under the 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,   any  errors,   omissions,
         interruptions or delays in transmission or delivery of any messages, by
         mail,  telecopier  or  otherwise,  or any errors in  translation  or in
         interpretation of technical terms, other than due to the Issuing Bank's
         gross negligence or willfull misconduct;

                           (v) Any defense based upon the failure of any drawing
         under a Letter  of  Credit to  conform  to the  terms of the  Letter of
         Credit (the Issuing Bank's sole obligation,  in determining  whether to
         pay under any Letter of Credit,  being to examine documents required to
         be  delivered  under such  Letter of Credit in good  faith and  without
         gross  negligence to ascertain that such documents appear on their face
         to comply with the terms of such Letter of Credit), any non-application
         or  misapplication by the beneficiary or any transferee of the proceeds
         of such  drawing or any other act or  omission of such  beneficiary  or
         transferee in connection with such Letter of Credit;

                          (vi)      The exchange, release, surrender or
         impairment of any Collateral or other security for the Credit
         Obligations;

                         (vii)      The occurrence of any Default or Event of
         Default; or

                        (viii)  Subject to the  Issuing  Bank's  obligation  set
         forth in the parenthetical in clause (v) above, any other  circumstance
         or  event  whatsoever,   including,   without  limitation,   any  other
         circumstance that might otherwise constitute a defense available to, or
         a discharge of, the Borrower or a guarantor.

None of the  foregoing  shall  impair,  prevent or  otherwise  affect any of the
rights and powers  granted to the Issuing  Bank  hereunder.  Any action taken or
omitted to be taken by the Issuing Bank under or in  connection  with any Letter
of Credit,  if taken or omitted in the  absence of gross  negligence  or willful
misconduct, shall be


                                                       -50-

<PAGE>



binding  upon the  Borrower  and each L/C  Participant  and shall not  create or
result  in any  liability  of  the  Issuing  Bank  to the  Borrower  or any  L/C
Participant.

         (h) If at any time after the Closing  Date the Issuing  Bank or any L/C
Participant  determines that the introduction of or any change in any applicable
law, rule,  regulation,  order, guideline or request or in the interpretation or
administration   thereof  by  any  Governmental   Authority   charged  with  the
interpretation or administration  thereof,  or compliance by the Issuing Bank or
any L/C Participant with any request or directive by any such authority (whether
or not  having  the  force of law)  shall  either  (i)  impose,  modify  or make
applicable any reserve, deposit, capital adequacy or similar requirement against
Letters  of Credit  issued by the  Issuing  Bank or  participated  in by any L/C
Participant or (ii) impose on the Issuing Bank or any L/C  Participant any other
conditions relating,  directly or indirectly, to this Agreement or any Letter of
Credit,  and the result of any of the  foregoing  is to increase the cost to the
Issuing Bank or L/C Participant of issuing,  maintaining or participating in any
Letter of Credit,  or to reduce the amount of any sum received or  receivable by
the Issuing Bank or such L/C Participant  hereunder or reduce the rate of return
on its capital with respect to Letters of Credit, then the Borrower will, within
fifteen (15) days after delivery to the Borrower by the Issuing Bank or such L/C
Participant of written demand  therefor (with a copy thereof to the Agent),  pay
to the Issuing Bank or such L/C  Participant  such  additional  amounts as shall
compensate the Issuing Bank or such L/C  Participant  for such increase in costs
or reduction in return.  A certificate  submitted to the Borrower by the Issuing
Bank or such L/C  Participant,  as the case may be (a copy of which  certificate
shall be sent by the Issuing Bank or such L/C Participant to the Agent), setting
forth the basis  for the  determination  of such  additional  amount or  amounts
necessary to compensate  the Issuing Bank or such L/C  Participant as aforesaid,
shall be conclusive and binding on the Borrower absent manifest error.

         (i) At any time and from time to time (i) during the  continuance of an
Event of Default,  the Agent,  at the  direction,  or with the  consent,  of the
Required  Lenders,  may  require  the  Borrower  to  deliver  to the Agent  such
additional  amount of cash as is equal to the  difference  between the aggregate
Stated Amount of all Letters of Credit at any time  outstanding  (whether or not
any  beneficiary  under any Letter of Credit  shall have drawn or be entitled at
such  time to draw  thereunder)  and the  amount  then on  deposit  in the  Cash
Collateral Account (as hereinafter defined) and (ii) in the event of a repayment
under Section 2.5(e),  the Agent will retain such amount as may then be required
to be  retained  under the proviso in Section  2.5(e),  such amount in each case
under  clauses  (i) and  (ii)  above to be held by the  Agent in a  non-interest
bearing cash collateral account (the "Cash Collateral Account") as security for,
and for application to, the Borrower's Reimbursement  Obligations.  In the event
of a drawing, and


                                                       -51-

subsequent  payment by the Issuing Bank,  under any Letter of Credit at any time
during which any amounts are held in the Cash Collateral Account, the Agent will
deliver to the  Issuing  Bank an amount  equal to the  Reimbursement  Obligation
created as a result of such  payment  (or,  if the amounts so held are less than
such  Reimbursement  Obligation,  all of such  amounts) to reimburse the Issuing
Bank therefor.  Any amounts  remaining in the Cash Collateral  Account after the
expiration  of all  Letters of Credit and  reimbursement  in full of the Issuing
Bank for all of its obligations  thereunder  shall be held by the Agent, for the
benefit of the  Borrower,  with such  amounts to be applied  against  the Credit
Obligations  in such order as (x) the  Borrower  may direct in the  absence of a
Default or an Event of Default, and (y) otherwise, the Agent may direct.

         (j)  Notwithstanding any termination of the Commitments or repayment of
the Loans,  or both,  the  obligations  of the Borrower  under this Section 2.17
shall  remain  in full  force and  effect  until  the  Issuing  Bank and the L/C
Participants  shall  have  no  further  obligations  to  make  any  payments  or
disbursements under any circumstances with respect to any Letter of Credit.

         In order to induce the Lenders to enter into this Credit Agreement,  to

makes the following  warranties and  representations  to the Agent,  the Issuing
Bank and each Lender:

         4.1.         Corporate Organization and Power.  The Borrower and each
of its Subsidiaries (a) is a corporation duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization; (b) is
qualified to do business and is in good standing in every other jurisdiction
where the nature of its business or the ownership of its properties requires it
to be so qualified and where the failure to be so qualified would have a
Material Adverse Effect, which jurisdictions are set forth on Schedule 4.1; (c)
except as set forth on Schedule 4.2 and except for Subsidiaries acquired or

Subsidiaries or Affiliates (other than its officers, directors and shareholders)

(d) has the corporate power to own and give a lien on and security interest in
its respective Collateral and to engage in the transactions contemplated hereby;
and (e) has the full corporate power, authority and legal right to execute and

to perform and observe the terms and provisions thereof.  Neither the Borrower
nor any of its Subsidiaries has, during the preceding


                                                       -57-

<PAGE>



five (5) years,  been known as or used any other corporate,  fictitious or trade
names in the United States other than as set forth on Schedule 4.1.

         4.2.  Subsidiaries.  Schedule 4.2 contains a complete and accurate list
of the Subsidiaries of the Borrower as of the Closing Date,  showing, as to each
Subsidiary,  the number of shares  and the owner of each class of capital  stock
authorized  and  outstanding.  Except as set forth on Schedule  4.2, all of such
issued  and  outstanding  shares  of  capital  stock  of all  of the  Borrower's
Subsidiaries  that are owned by the Borrower or its Subsidiaries  have been duly
authorized and validly issued, are fully paid and  nonassessable,  and are owned
by the Borrower,  free and clear of any liens, charges,  encumbrances,  security
interests, claims or restrictions of any nature whatsoever,  except for liens in
favor of the Agent,  for the  benefit  of the  Lenders,  granted  under the Loan
Documents, and there are no other equity securities of any Subsidiary issued and
outstanding or reserved for any purpose.

         4.3.   Enforceability   of  Loan   Documents;   Compliance  with  Other
Instruments.  Except as set forth on Schedule 4.3, each of the Loan Documents to
which the  Borrower or any  Guarantor  is a party,  as the case may be, has been
duly authorized by all necessary corporate action on the part of the Borrower or
such Guarantor,  has been validly executed and delivered by the Borrower or such
Guarantor and is the legal, valid and binding obligation of the Borrower or such
Guarantor, enforceable against the Borrower or such Guarantor in accordance with
its terms,  except as  enforceability  may be limited by applicable  bankruptcy,
insolvency,  reorganization,  moratorium  or similar laws  affecting  creditors'
rights  generally  or by general  principles  of equity.  Except as set forth in
Schedule 4.3,  neither the Borrower nor any of its Subsidiaries is in default in
any material  respect with respect to any indenture,  loan agreement,  mortgage,
lease,  deed or similar  agreement to which it is a party or by which it, or any
of its property, is bound. Neither the execution, delivery or performance of the
Loan  Documents  by the  Borrower  and the  Guarantors,  nor  compliance  by the
Borrower and the  Guarantors  therewith:  (a) conflicts or will conflict with or
results or will result in any breach of, or constitutes or will  constitute with
the passage of time or the giving of notice or both,  a default  under,  (i) any
Requirement  of Law or (ii) any material  agreement or  instrument  to which the
Borrower or any Guarantor is a party or by which it, or any of its property,  is
bound or (b) results or will result in the creation or  imposition  of any lien,
charge  or  encumbrance  upon  the  properties  of  the  Borrower  or any of its
Subsidiaries pursuant to any such agreement or instrument,  except for Permitted
Liens.

         4.4.         Use of Proceeds.  The Borrower's use of the proceeds of
any Loans made by the Lenders to the Borrower pursuant to this Agreement are and
will be legal and proper corporate uses, duly authorized by the Board of
Directors of the Borrower, and such uses


                                                       -58-

are and will be consistent with all applicable  laws and statutes,  as in effect
from time to time.

         4.5.         Governmental Authorization.

         (a) Except as set forth on Schedule 4.5, no  authorization,  consent or
approval  of, or  declaration  or filing  with,  any  Governmental  Authority is
required  for  the  valid  execution  and  delivery  by  the  Borrower  and  its
Subsidiaries of the Loan Documents to which they are a party or the consummation
by the Borrower and its Subsidiaries of the transactions contemplated hereby and
thereby,   including  repayment  of  the  Credit  Obligations  or  pledging  the
Collateral, except for the filing and recording of the Financing Statements. The
Borrower and its  Subsidiaries  have,  and are in good standing with respect to,
all  material  governmental  approvals,  permits,   certificates,   inspections,
consents and franchises  necessary to continue to conduct business as heretofore
conducted and to own or lease and operate its respective properties as now owned
or  leased  by it.  None  of such  material  approvals,  permits,  certificates,
consents,  or franchises contains any term,  provision,  condition or limitation
more burdensome than such as are generally  applicable to Persons engaged in the
same or similar  business  as the  Borrower or its  Subsidiaries,  except to the
extent that any such  increased  burden by such term,  provision,  condition  or
limitation will not have a Material Adverse Effect.

         (b) The  Borrower  and  each of its  Subsidiaries  has,  to the  extent
applicable,  obtained (or been duly assigned) and maintains in good standing all
material  licenses as required by the  relevant  state and federal  Governmental
Authorities,  for the  ownership  and  operation of its  businesses as currently
operated.

         4.6.         Financial Statements.

         (a) The Borrower has heretofore  furnished to each Lender copies of the
Financial Statements.  The Financial Statements have been prepared in accordance
with Generally  Accepted  Accounting  Principles  (subject,  with respect to the
unaudited  Financial  Statements,  to the absence of notes required by Generally
Accepted  Accounting  Principles and to normal year-end audit  adjustments)  and
present fairly the financial  position of the Borrower and its Subsidiaries on a
consolidated  basis as of the dates  thereof  and the  consolidated  results  of
operations  of the  Borrower  and its  Subsidiaries  for the periods then ended.
Except as fully reflected in the most recent Financial  Statements and the notes
thereto, as of the Closing Date, and taking into account the Loans to be made on
the Closing Date and the other transactions  contemplated by the Loan Documents,
there  will be no  material  liabilities  or  obligations  with  respect  to the
Borrower or any of its Subsidiaries of any nature whatsoever  (whether absolute,
contingent  or  otherwise  and  whether or not due).  Since the date of the most
recent Financial Statements, there has been no Material Adverse Change,


                                                       -59-

<PAGE>



and, to the knowledge of the Borrower,  no Material Adverse Change is threatened
or reasonably likely to occur,  except as set forth on Schedule 4.6. Neither the
Borrower  nor any of its  Subsidiaries  has  directly  or  indirectly  declared,
ordered, paid, made or set apart any amounts or property for any dividend, share
acquisition  or other  distribution,  or agreed to do so, except as permitted by
Section 6.8.

         (b) The Borrower has  prepared,  and has  heretofore  furnished to each
Lender copies of, annual  projected  balance sheets and statements of income and
cash  flows  of the  Borrower  and its  Subsidiaries  for the  five-year  period
commencing on the date set forth therein (the "Projections").  In the opinion of
the  Borrower's   management,   the  assumptions  used  in  preparation  of  the
Projections were reasonable when made and are reasonable as of the Closing Date.
The Projections  have been prepared in good faith by the executive and financial
personnel of the Borrower in light of the  historical  financial  performance of
the Borrower and its Subsidiaries  and the financial and operating  condition of
the  Borrower  and its  Subsidiaries  at the time  prepared,  give effect to the
transactions  contemplated  by the Loan  Documents  and,  in the  opinion of the
Borrower's management,  represent, as of the Closing Date, a reasonable estimate
of the future  performance  and  financial  condition  of the  Borrower  and its
Subsidiaries,  subject to the uncertainties and  approximations  inherent in any
projections  and  without   representation   or  warranty  that  such  projected
performance and financial condition will actually be achieved.

         4.7.         Solvency.  The Borrower and each of its Domestic

each of its Subsidiaries is presently maintained.

         4.9. Leased Properties. Schedule 4.9 lists, as of the Closing Date, (i)
all real property  leased by the Borrower or any of its  Subsidiaries,  and (ii)
all  personal  property  leased  by the  Borrower  or  any  of its  Subsidiaries
requiring lease payments in excess of $100,000 per year,  including in each case
the name of the lessors and a description of the locations of such property. The
Borrower and each of its Subsidiaries enjoys peaceful and undisturbed possession
under all of its leases, and all such leases are valid


                                                       -60-

other properties and assets, including, without limitation, the assets reflected
in the most recent Financial Statements (except as sold or otherwise disposed of
since the date thereof in the ordinary  course of  business),  in each case free

any of its Subsidiaries has signed any other financing statement or any security

         4.14.  First  Priority.  The provisions of the Loan Documents  (whether
executed and delivered prior to or on the Closing Date or  thereafter),  are and
will be  effective  to  create in favor of the  Agent,  for the  benefit  of the
Lenders, upon the initial extension of credit hereunder and the proper filing of

         (b) Each such Plan is in compliance  in all material  respects with the
applicable  provisions of ERISA,  the Internal Revenue Code and other federal or
state law,  including all requirements  under the Internal Revenue Code or ERISA
for filing  reports  (which are true and correct in all material  respects as of
the date filed),  and benefits have been paid in accordance  with the provisions
of each such Plan.

         (c)          The form of each Plan intended to be qualified under
Section 401 of the Internal Revenue Code ("Qualified Plan") to the

knowledge of the Borrower  qualifies  under Section 401 of the Internal  Revenue
Code, and the trusts created  thereunder  are, to the knowledge of the Borrower,
exempt  from tax under the  provisions  of Section 501 of the  Internal  Revenue
Code, and to the knowledge of the Borrower nothing has occurred that would cause
the loss of such qualification or tax-exempt status.

         (d) There is no material outstanding  liability under Title IV of ERISA
with  respect  to any Plan  maintained  or  sponsored  by the  Borrower  and its
Subsidiaries  (as to which the Borrower or any of its  Subsidiaries is or may be
liable),  nor  with  respect  to any Plan to which  any of the  Borrower  or its
Subsidiaries  (wherein  the  Borrower  or any of its  Subsidiaries  is or may be
liable) contributes or is obligated to contribute.

         (e) None of the  Qualified  Plans  subject to Title IV of ERISA has any
material unfunded benefit  liability as defined in Section  4001(a)(18) of ERISA
(as to which the Borrower or any of its Subsidiaries is or may be liable).

         (f) No Plan  maintained  or  sponsored  by the  Borrower  or any of its
Subsidiaries  provides  medical or other  welfare  benefits or extends  coverage
relating to such  benefits  beyond the date of a  participant's  termination  of
employment with the Borrower or such  Subsidiary,  except to the extent required
by Section  4980B of the  Internal  Revenue  Code and at the sole expense of the
participant  or  the  beneficiary  of the  participant  to  the  fullest  extent
permissible  under such Section of the Internal  Revenue Code.  The Borrower and
its  Subsidiaries  have  complied in all material  respects  with the notice and
continuation  coverage  requirements  of Section  4980B of the Internal  Revenue
Code.

         (g) No ERISA Event has occurred or is reasonably expected to occur with
respect  to any Plan  maintained  or  sponsored  by the  Borrower  or any of its
Subsidiaries or to which the Borrower or any of its Subsidiaries is obligated to
contribute.

         (h) As of the Closing  Date,  there are no pending or, to the knowledge
of the  Borrower,  threatened  claims,  actions or lawsuits,  other than routine
claims for benefits in the usual and  ordinary  course,  asserted or  instituted
against  (i)  any  Plan   maintained  or  sponsored  by  the  Borrower  and  its
Subsidiaries or their assets, or (ii) any fiduciary with respect to any Plan for
which the  Borrower or any of its  Subsidiaries  may be  directly or  indirectly
liable, through indemnification obligations or otherwise.

         (i) Neither the Borrower nor any of its  Subsidiaries  has incurred or,
to the knowledge of the Borrower,  reasonably expects to incur (i) any liability
(and no event has occurred that, with the giving of notice under Section 4219 of
ERISA,  would result in such liability) under Section 4201 or 4243 of ERISA with
respect to a Multiemployer Plan or (ii) any liability under Title IV of ERISA

respect to a Plan.

         (j) Neither  the  Borrower  nor any of its  Subsidiaries  has  engaged,
directly or indirectly,  in a nonexempt  prohibited  transaction  (as defined in
Section 4975 of the Internal Revenue Code or Section 406 of ERISA) in connection
with any Plan that has a Material Adverse Effect.

         4.18.  Compliance with Laws. The Borrower and each of its  Subsidiaries

XIX of the Social Security Act (42 U.S.C. ss.ss. 1395 et seq. and ss.ss. 1396 et
seq.,  respectively,  as amended  from time to time),  except to the extent that
noncompliance will not have a Material Adverse Effect.

         4.19.        Environmental Matters.

         (a)  Except as set  forth on  Schedule  4.19  attached  hereto,  (i) no

any  part  of  the  Realty,   including  the  groundwater  located  thereon  and
thereunder,  with any Hazardous  Substance  during the  ownership,  occupancy or

order or other request to take "removal" or "remedial"  action (as defined under
Environmental Laws) or to pay for the costs of cleaning up such a site; and

         (b) All  activities  and  operations  of the  Borrower  and each of its
Subsidiaries  comply  in all  material  respects  with the  requirements  of all
applicable   Environmental   Laws  of  all   Governmental   Authorities   having

         (a) Neither the Borrower nor any of its  Subsidiaries  owns any "margin
stock"  within the meaning of  Regulation  U. None of the  proceeds of the Loans
will be used, directly or indirectly,  for the purpose of purchasing or carrying

incurred to purchase or carry margin  stock or for any other  purpose that would
violate  Regulation G,  Regulation U,  Regulation T or Regulation X or any other

circumstances under which they were made, not misleading.

         4.22. Contracts; Labor Disputes.  Neither the Borrower nor any of its
Subsidiaries is a party to any contract or agreement, or subject to any charge,
corporate restriction, judgment, injunction, decree, rule, regulation or order
of any court or other Governmental  Authority, that has or could  reasonably  be
expected to have a Material  Adverse  Effect. Neither the Borrower nor any of

occurred and is continuing.

         4.24.  Single  Business  Enterprise.  The Borrower  and the  Guarantors
operate,  and  intend to  operate,  as a single  business  enterprise.  Although
separate  entities,  the  Borrower  and the  Guarantors  operate  under a common
business plan. Each of the Borrower and the Guarantors will accordingly  benefit
from the  financing  arrangement  established  by this  Agreement.  The Borrower

Guarantor to execute and deliver the Guaranty  Documents  in  committing  to the
Facilities.

disclosures  provided  on any of  the  Schedules  attached  hereto  (other  than
Schedules  relating solely to  representations  and warranties made solely as of
the Closing Date) become outdated or incorrect in any material respect or in the
event additional disclosure is required in connection with any Acquisition,  the
Borrower  shall  promptly  provide the Agent in writing  with such  revisions or
updates to such Schedule as may be necessary or appropriate to update or correct
the  same;  provided,  however,  that no  Schedule  shall be deemed to have been
amended,  modified or  superseded  by any such  correction  or update that would
disclose the occurrence of an event or condition which  constitutes a Default or
Event of Default,  nor shall any breach of warranty or representation  resulting
from the  inaccuracy  or  incompleteness  of any such Schedule be deemed to have
been cured  thereby,  unless and until the Required  Lenders,  in their sole and
absolute discretion, shall have accepted in writing such revisions or updates to
such Schedule.

to such acquisition of assets;

         (h) The  occurrence  of a Change of Control  (such notice being sent to
the Agent and Lenders no later than five (5)  Business  Days after the  Borrower

(5) Business Days after the Change of Control);

         (i)          Any other matter that has resulted, or is likely to

         (a)  Maintain  and  preserve  in full force and  effect  its  corporate
existence,  except as  otherwise  permitted  by Section  6.1,  and all  material
rights,  privileges and  franchises;  provided,  however,  that the Borrower may
permit the dissolution of any of its  Subsidiaries  (and any such Subsidiary may
suffer such  dissolution) if, at the time of such  dissolution,  such Subsidiary
has no assets, engages in no business and otherwise has no activities other than
activities  related  to the  maintenance  of its  corporate  existence  and good
standing;

         (b) Conduct its business in an orderly and efficient  manner,  keep its
properties in good working order and condition  (normal wear and tear  excepted)
and from time to time make all needed repairs to, renewals of or replacements of
its properties (except to the extent that any of such properties are obsolete or
are being replaced) so that the efficiency of its business  operations  shall be
fully maintained and preserved; and

         (c)  File  or  cause  to be  filed  in a  timely  manner  all  reports,
applications,  estimates  and licenses  required by any  Governmental  Authority
that,  if not timely  filed,  could  reasonably  be  expected to have a Material
Adverse Effect.

         5.4.  Payment of Debt. The Borrower shall,  and shall cause each of its
Subsidiaries  to, pay all Debt when due within the terms  thereof  (unless being
contested in good faith by appropriate proceedings) and all other obligations in
accordance with customary trade practices.

         5.5.         Maintenance of Insurance.

         (a) The  Borrower  will,  and will cause each of its  Subsidiaries  to,

the Collateral,  wherever  located,  and all real property owned by it, covering
property  and  casualty,   commercial  general  liability,   product  liability,
professional

liability,  business interruption,  earthquake, flood, boiler, fidelity and such
other risks, and in such amounts and with such insurance companies,  as shall be
reasonably  satisfactory to the Agent (and in any event in such amounts as shall
be  adequate  to cover  the  Collateral),  and  will,  at the  Closing,  deliver
certificates  of such  insurance  to the Agent with  satisfactory  loss  payable
endorsements  naming the Agent as an additional loss payee,  additional  insured
and/or mortgagee  thereunder,  as its interests may appear,  as appropriate.  As
soon as  practicable  after the Closing Date,  the Borrower shall deliver to the
Agent  certified  copies  of  the  original  policies  of all  insurance  on the
Collateral.

         (b) Each such policy of insurance shall contain a clause  requiring the
insurer to give not less than thirty (30) days prior written notice to the Agent
before any cancellation of the policies for any reason whatsoever,  and a clause
that the interest of the Agent shall not be impaired or  invalidated  by any act
or  neglect  of the  Borrower  or any of its  Subsidiaries  or the  owner of the
property nor by the occupation of the premises  wherein such property is located
for purposes  more  hazardous  than are  permitted by such policy.  The Borrower
hereby directs,  and will cause each of its Subsidiaries to direct, all insurers
under  policies of property and casualty  insurance on the Collateral to pay all
proceeds  payable  thereunder  directly to the Agent when such  proceeds,  on an
aggregate  basis,  exceed $250,000.  The Agent, on behalf of the Lenders,  shall
hold all such proceeds for the account of the Borrower and its Subsidiaries.  So
long as no Default or Event of Default has occurred and is continuing, the Agent
shall,  at the  Borrower's  request,  disburse  such proceeds for the purpose of
replacing or repairing  destroyed or damaged assets,  as and when required to be
paid  and  upon  presentation  of  evidence  satisfactory  to the  Agent of such
required payments and such other documents as the Agent may reasonably  request,
or shall apply such  proceeds in whole or in part as a prepayment  of the Loans,
in such order as the Borrower may determine.  Upon and during the continuance of
a Default  or Event of  Default,  the  Agent  shall  apply  such  proceeds  as a
prepayment of the Term Loans in accordance  with  Sections  2.5(a)  (except that
such prepayment shall be applied to reduce the aggregate  outstanding  principal
amount of the Term  Loans,  ratably  among the  Lenders  holding  Term  Loans in
proportion  to the  principal  amount held by each,  with such  reduction  to be
applied  to the  scheduled  principal  payments  on the  Term  Loans  due  under
subsection  (c) above,  in the inverse  order of  maturity  and shall be applied
first to Base Rate  Loans and then to LIBOR  Loans)  and,  to the  extent of any
excess, as a prepayment of the Revolving Credit Loans in accordance with Section
2.5(a).  If an Event of Default has occurred,  the Borrower  hereby  irrevocably
makes, constitutes and appoints the Agent (and all officers, employees or agents
designated by the Agent) as its true and lawful agent (and attorney-in-fact) for
the purpose of making,  settling and  adjusting  claims  under such  policies of
insurance, endorsing its name or the name of any Subsidiary on any check, draft,

for making all determinations and decisions with respect to such
policies of insurance.

         (c) If the  Borrower  or any of its  Subsidiaries  fails to obtain  and
maintain any of the policies of insurance required to be maintained hereunder or
to pay any premium in whole or in part,  then the Agent may,  at the  Borrower's
expense,  without waiving or releasing any obligation or Default by the Borrower
hereunder,  procure  the same,  but shall not be  required to do so. All sums so
disbursed  by the Agent,  including  reasonable  attorneys'  fees,  court costs,
expenses and other charges  related  thereto,  shall be payable on demand by the
Borrower to the Lenders and shall be additional  Credit  Obligations  hereunder,
secured by the Collateral.

         (d) Upon the  reasonable  request of the Agent  from time to time,  the

Governmental Authority having jurisdiction over it.

         (b) The Borrower shall,  and shall cause each of its  Subsidiaries  to,

notice to inspect  its  properties  and to examine or audit its books,  records,
reports, accounts and other papers and make copies and memoranda of them, and to
discuss its affairs,  finances and accounts with its officers and employees and,
upon notice to the Borrower,  the independent public accountants of the Borrower
and its  Subsidiaries  (and by  this  provision  the  Borrower  and  each of its
Subsidiaries  authorizes said accountants to discuss the finances and affairs of
the Borrower or such  Subsidiary),  all at such reasonable times and as often as

its Subsidiaries  to: (i) make timely payment of contributions  required to meet
the minimum  funding  standards  set forth in ERISA with respect to any Employee

action or inaction  could be a material  liability of the Borrower or any of its
Subsidiaries to the Pension Benefit  Guaranty  Corporation or to a Multiemployer
Plan.  Borrower  shall  not,  nor shall it permit  any of its  Subsidiaries  to,
participate in any Prohibited Transaction

penalty  under  ERISA or  material  tax under the  Internal  Revenue  Code.  The
Employee Plans of the Borrower and each of its Subsidiaries shall be operated in
such a manner  that  neither  the  Borrower  nor any  Subsidiary  will incur any
material tax liability  under Section 4980B of the Internal  Revenue Code or any
material liability to any qualified beneficiary as defined in Section 4980B.

         5.8.  Payment of Taxes. The Borrower shall, and shall cause each of its
Subsidiaries  to, pay and  discharge  all taxes,  assessments  and  governmental
charges or levies  imposed  upon it or upon its income or  profits,  or upon any
properties  belonging to it, prior to the date on which  penalties  would attach
thereto,  and all lawful claims that,  if unpaid,  might become a lien or charge
upon any of its properties;  provided,  however, that the Borrower or any of its
Subsidiaries may in good faith by appropriate proceedings and with due diligence
contest  any such tax,  assessment,  charge,  levy or claim if the  Borrower  or

its Subsidiaries  to, (i) have all material  licenses,  permits,  certifications
approvals and authorizations  required by Governmental  Authorities necessary to
the  ownership,  occupation  or use  of its  properties  or the  conduct  of its
business, and maintain the same at all times in full force and effect, except to
the extent that a failure to have or maintain the same would not have a Material
Adverse Effect,  and (ii) comply with all  Requirements of Law in respect of the
conduct of its business, the ownership of its property and the Collateral, other
than those the failure to comply  with which  would not have a Material  Adverse
Effect.

         5.10. Name Change.  The Borrower shall notify the Agent and the Lenders
at least fifteen (15) days prior to the effective date of any change of the name
of the Borrower or any of its Subsidiaries, and prior to such effective date the
Borrower  or  such  Subsidiary  shall  execute  any  amended  or  new  Financing
Statements  and other Loan  Documents  necessary  to maintain  and  continue the
perfected security interest of the Agent in all of the Collateral and shall take
such other  actions and executed  such  documents as the Agent shall  reasonably
request.

intercompany  promissory  note with  respect to  advances  of any portion of the
Loans to any  Subsidiary  of the Borrower and any other  amounts  owing from any
Subsidiary of the Borrower to the Borrower from time to time, and shall promptly

         (b) Should any Subsidiary  become a debtor under the  Bankruptcy  Code,
the Agent, on behalf of the Lenders,  is authorized,  but not required,  to file
proofs of claim with respect to such intercompany Debt on behalf of the Borrower
and vote the rights of the Borrower in any plan of reorganization. The Agent, on
behalf of the  Lenders,  is further  empowered to demand,  sue for,  collect and
receive  every  payment and  distribution  on such Debt owing to the Borrower in
such Subsidiary's bankruptcy proceeding.

Investments,  loans,  or  other  distributions  from  the  Borrower  or  another
Subsidiary,  in excess of $250,000 in the case of an existing  Subsidiary  which
previously  had assets with a gross value less than  $250,000)  will execute and
deliver to the Agent (with  sufficient  copies for each  Lender) an amendment or
accession to the Guaranty Agreement,  in form and substance  satisfactory to the
Agent,  pursuant to which such new Subsidiary  shall become a party thereto,  as

with the  certificates  representing  such  capital  stock  or  other  ownership
interests and stock powers duly  executed in blank,  and (iii) the Borrower will
cause each such new  Subsidiary  to execute  and  deliver,  and will cause to be

enumeration of the Agent's and the Lenders' rights and remedies set forth in
this Agreement is not intended to be exhaustive, and the exercise by the  Agent

any other rights or remedies, all of which shall be cumulative,  and shall be in
addition to any other right or remedy  given  hereunder,  under the Loan
Documents or under any other  agreement  between the Borrower or any of its
Subsidiaries  and the Agent or the Lenders or that may now or hereafter exist in

the part of the Agent or any Lender in exercising any right,  power or privilege
shall operate as a waiver thereof,  nor shall any single or partial  exercise of
any such right, power or privilege preclude other or further exercise thereof or
the exercise of any other right,  power or privilege or shall be construed to be
a waiver of any Event of Default.  No course of dealing  between the Borrower or
any of its  Subsidiaries  and the  Agent  or the  Lenders  or  their  agents  or
employees  shall be effective to change,  modify or discharge  any  provision of
this  Agreement or any of the other Loan  Documents or to constitute a waiver of

Agreement  or any other Loan  Document,  express or  implied,  is intended to or
shall be so construed as to impose upon the Agent any obligations or liabilities
in respect of this Agreement or any other Loan Document  except as expressly set
forth  herein or therein.  The Agent may  execute  any of its duties  under this
Agreement or any other Loan Document by or through  agents or  attorneys-in-fact
and shall not be  responsible  for the negligence or misconduct of any agents or
attorneys-in-fact  that it selects  with  reasonable  care.  The Agent  shall be
entitled to consult with legal counsel, independent public accountants and other
experts selected by it with respect to all matters  pertaining to this Agreement
and the other Loan  Documents and its duties  hereunder and thereunder and shall
not be liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel,  accountants or experts. The Lenders
hereby  acknowledge  that the  Agent  shall  not be  under  any duty to take any
discretionary  action  permitted to be taken by it pursuant to the provisions of
this  Agreement  or any other  Loan  Document  unless it shall be  requested  in
writing to do so by the Required  Lenders (or, where a higher  percentage of the
Lenders is expressly required hereunder, such Lenders).

         9.3. Exculpatory Provisions. Neither the Agent nor any of its officers,
directors,  employees,  agents,  attorneys-in-fact  or  Affiliates  shall be (i)
liable for any action taken or omitted to be taken by it or such Person under or
in connection with the Loan Documents, except for its or such Person's own gross
negligence or willful  misconduct,  (ii) responsible in any manner to any Lender
for any recitals, statements, information,  representations or warranties herein
or in any other  Loan  Document  or in any  document,  instrument,  certificate,
report or other writing delivered in connection  herewith or therewith,  for the
execution,  effectiveness,  genuineness, validity, enforceability or sufficiency
of this Agreement or any other Loan Document,  or for the financial condition of
the  Borrower,  its  Subsidiaries  or any other  Person,  or (iii)  required  to
ascertain or make any inquiry concerning the performance or observance of any of
the terms, provisions or conditions of this Agreement or any other Loan Document
or the existence or possible existence of any Default or Event of Default, or to
inspect  the  properties,  books  or  records  of  the  Borrower  or  any of its
Subsidiaries.

         9.4.  Reliance by the Agent.  The Agent shall be entitled to rely,  and
shall be fully  protected  in relying,  upon any notice,  statement,  consent or
other communication  (including,  without limitation,  any thereof by telephone,
telecopy,  telex,  telegram or cable) believed by it in good faith to be genuine
and  correct  and to have  been  signed,  sent or made by the  proper  Person or
Persons.  The Agent may deem and treat each Lender as the owner of its  interest
hereunder  for all  purposes  hereof  unless  and until a written  notice of the
assignment,  negotiation or transfer  thereof shall have been given to the Agent
in accordance with the


                                                       -89-

<PAGE>



provisions of this Agreement. The Agent shall be entitled to refrain from taking
or omitting to take any action in  connection  with this  Agreement or any other
Loan Document (i) if such action or omission would, in the reasonable opinion of
the Agent,  violate any applicable law or any provision of this Agreement or any
other Loan  Document or (ii) unless and until it shall have received such advice
or  concurrence of the Required  Lenders (or,  where a higher  percentage of the
Lenders is expressly required  hereunder,  such Lenders) as it deems appropriate
or it shall  first have been  indemnified  to its  satisfaction  by the  Lenders
against any and all  liability  and expense that may be incurred by it by reason
of taking,  continuing  to take or  omitting  to take any such  action.  Without
limiting  the  foregoing,  no Lender  shall have any right of action  whatsoever
against the Agent as a result of the Agent's  acting or  refraining  from acting
hereunder or under any other Loan Document in accordance  with the  instructions
of the  Required  Lenders  (or,  where a higher  percentage  of the  Lenders  is
expressly  required  hereunder,  such Lenders),  and such  instructions  and any
action taken or failure to act pursuant thereto shall be binding upon all of the
Lenders (including all subsequent Lenders).

         9.5.  Non-Reliance  on Agent and Other Lenders.  Each Lender  expressly
acknowledges  that  neither  the  Agent  nor  any  of its  officers,  directors,
employees,  agents,  attorneys-in-fact or Affiliates has made any representation
or  warranty  to it and that no act by the  Agent or any such  Person  hereafter
taken, including any review of the affairs of the Borrower and its Subsidiaries,
shall be deemed to constitute any representation or warranty by the Agent to any
Lender.  Each Lender represents to the Agent that (i) it has,  independently and
without  reliance upon the Agent or any other Lender and based on such documents
and  information  as it has deemed  appropriate,  made its own  appraisal of and
investigation into the business, prospects,  operations,  properties,  financial
and other condition and  creditworthiness  of the Borrower and its  Subsidiaries
and made its own decision to enter into this  Agreement and extend credit to the
Borrower  hereunder,  and (ii) it will,  independently and without reliance upon
the Agent or any other Lender and based on such documents and  information as it
shall deem  appropriate at the time,  continue to make its own credit  analysis,
appraisals and decisions in taking or not taking action  hereunder and under the
other Loan  Documents and to make such  investigation  as it deems  necessary to
inform itself as to the business, prospects,  operations,  properties, financial
and other condition and  creditworthiness  of the Borrower and its Subsidiaries.
Except as expressly provided in this Agreement and the other Loan Documents, the
Agent shall have no duty or responsibility,  either initially or on a continuing
basis, to provide any Lender with any credit or other information concerning the
business,  prospects,  operations,  properties,  financial or other condition or
creditworthiness of the Borrower,  its Subsidiaries or any other Person that may
at any  time  come  into the  possession  of the  Agent or any of its  officers,
directors, employees, agents, attorneys-in-fact or Affiliates.

         9.6. Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the  occurrence of any Default or Event of Default unless the Agent
shall have received  written  notice from the Borrower or a Lender  referring to
this  Agreement,  describing  such  Default or Event of Default and stating that
such notice is a "notice of default." In the event that the Agent  receives such
a  notice,  the  Agent  will  give  notice  thereof  to the  Lenders  as soon as
reasonably practicable; provided, however, that if any such notice has also been
furnished  to the  Lenders,  the Agent  shall have no  obligation  to notify the
Lenders with respect thereto. The Agent shall (subject to Sections 9.4 and 10.8)
take such  action  with  respect  to such  Default  or Event of Default as shall
reasonably be directed by the Required Lenders;  provided that, unless and until
the Agent shall have received such  directions,  the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such  Default  or Event of Default  as it shall  deem  advisable  in the best
interests  of the  Lenders.  Each Lender  shall  promptly  give the Agent such a
notice upon its actual knowledge of a Default or an Event of Default;  provided,
however, that the failure of any Lender to deliver such notice shall not, in the
absence of gross negligence or willful  misconduct,  affect its rights hereunder
or under the other  Loan  Documents.  Each  Lender  agrees  that the  rights and
remedies  granted  under this  Agreement and the other Loan  Documents  shall be
exercised  solely by the  Agent,  at the  direction  or with the  consent of the
Required  Lenders,  and that no  Lender  shall  have any right  individually  to
exercise  any such  right or remedy  except  to the  extent,  if any,  expressly
provided herein or therein.

         9.7.  Indemnification.  To the extent the Agent is not reimbursed by or
on behalf of the Borrower,  and without  limiting the obligation of the Borrower
to do so,  the  Lenders  agree (i) to  indemnify  the  Agent  and its  officers,
directors,  employees,  agents,  attorneys-in-fact  and  Affiliates,  ratably in
proportion to their  respective  percentages as used in determining the Required
Lenders  as of  the  date  of  determination,  from  and  against  any  and  all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including, without limitation, attorneys' fees and expenses) or
disbursements  of any kind or nature  whatsoever that may at any time (including
at any time following the repayment in full of the Loans and the  termination of
the Commitments) be imposed on, incurred by or asserted against the Agent in any
way relating to or arising out of this  Agreement or any other Loan  Document or
any  documents  contemplated  by or  referred  to  herein  or  the  transactions
contemplated hereby or thereby or any action taken or omitted by the Agent under
or in connection with any of the foregoing, and (ii) to reimburse the Agent upon
demand,  ratably  in  proportion  to  their  respective  percentages  as used in
determining  the  Required  Lenders  as of the  date of  determination,  for any
expenses  incurred  by the  Agent for the  benefit  of the  Lenders  (including,
without limitation, attorneys' fees and expenses and compensation of agents and


                                                       -91-

<PAGE>



employees  paid for  services  rendered  on  behalf of the  Lenders);  provided,
however,  that no Lender  shall be liable for any  portion of such  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or  disbursements  to the extent resulting from the gross negligence or
willful misconduct of the party to be indemnified.

         9.8.  The  Agent  in  its  Individual  Capacity.  With  respect  to its
Commitments,  the Loans made by it, the  Letters of Credit  issued by it and the
Notes issued to it, the Agent in its individual  capacity and not as Agent shall
have the same rights and powers under the Loan Documents as any other Lender and
may  exercise  the same as  though  it were not  performing  the  agency  duties
specified  herein;  and the terms  "Lenders,"  "Required  Lenders,"  "holders of
Notes" and any  similar  terms  shall,  unless  the  context  clearly  otherwise
indicates,  include  the  Agent in its  individual  capacity.  The Agent and its
Affiliates may accept deposits from,  lend money to and generally  engage in any
kind of banking,  trust, financial advisory or other business with the Borrower,
any of its Subsidiaries or any of their respective  Affiliates as if it were not
performing  the agency duties  specified  herein,  and may accept fees and other
consideration  from any of them for services in connection  with this  Agreement
and otherwise without having to account for the same to the Lenders.

         9.9.  Successor  Agent.  Subject to the appointment and acceptance of a
successor as provided below, the Agent may resign at any time by giving ten (10)
Business  Days' prior written  notice to the Borrower and the Lenders.  Upon any
such notice of  resignation,  the  Required  Lenders will appoint from among the
Lenders a successor  to the Agent.  If no successor to the Agent shall have been
so appointed by the Required  Lenders and shall have accepted  such  appointment
within such  ten-Business Day period,  then the retiring Agent may, on behalf of
the Lenders,  appoint a successor  Agent,  which shall be a  commercial  bank or
trust  company  organized  under the laws of the United States of America or any
state   thereof  and  having  a  combined   capital  and  surplus  of  at  least
$1,000,000,000.  Upon the acceptance of any  appointment as Agent by a successor
Agent,  such successor Agent shall  thereupon  succeed to and become vested with
all the rights,  powers,  privileges and duties of the retiring  Agent,  and the
retiring Agent shall be discharged from its duties and obligations hereunder and
under the other Loan Documents. After any retiring Agent's resignation as Agent,
the  provisions  of this  Article  shall  inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent.

         9.10.        Collateral Matters.

         (a) The Agent is hereby  authorized  on behalf of the Lenders,  without
the necessity of any notice to or further consent from the Lenders, from time to
time (but  without  any  obligation)  to take any  action  with  respect  to the
Collateral and the Security


                                                       -92-

<PAGE>



Documents that may be necessary to perfect and maintain perfected the Liens upon
the Collateral granted pursuant to the Security Documents.

         (b) The Lenders  hereby  authorize the Agent,  at its option and in its
discretion,  to  release  any  Lien  granted  to or held by the  Agent  upon any
Collateral (i) upon termination of the Commitments and payment in full of all of
the Obligations, (ii) constituting property sold or to be sold or disposed of as
part of or in connection with any disposition  expressly  permitted hereunder or
under any other Loan Document or to which the Required Lenders have consented or
(iii)  otherwise  pursuant  to and in  accordance  with  the  provisions  of any
applicable  Loan  Document.  Upon request by the Agent at any time,  the Lenders
will confirm in writing the Agent's authority to release Collateral  pursuant to
this subsection (b).


                                    ARTICLE X

                                  MISCELLANEOUS

         10.1.        Survival.

         (a) The  representations  and  warranties  made by or on  behalf of the
Borrower or any of its  Subsidiaries  in this  Agreement  and in each other Loan
Document  shall survive the  execution  and delivery of this  Agreement and each
such other Loan Document. Notwithstanding any other provision herein or anything
provided  or implied by law to the  contrary,  no  termination  or  cancellation
(regardless of cause or procedure) of the Commitments,  this Agreement or any of
the other  Loan  Documents  shall in any way  affect or impair  the  rights  and
obligations  of the parties  hereto with respect to any of the provisions of (i)
Section  10.3,  (ii)  Section  2.15 or (iii) this  Agreement  and the other Loan
Documents  relating  to  indemnification  or  payment  of  costs  and  expenses,
including,  without  limitation,  all of the  provisions  of  Sections  2.11(a),
2.11(b),  2.12,  2.13,  2.17(h),  9.7,  10.6 and 10.7,  and, in each case,  such
provisions shall survive any such termination or cancellation and the making and
repayment of the Loans.

         (b) The Borrower, the Agent and the Lenders agree that: (i) Articles IV
and V and the other applicable  provisions of this Credit Agreement are intended
as the Agent's (on behalf of the Lenders)  written request for information  (and
the  Borrower's  response)  concerning the  environmental  condition of the real
property;  and (ii) each provision in this Credit  Agreement  (together with any
indemnity  applicable  to a breach of any such  provision)  with  respect to the
environmental  condition  of the  Realty  is  intended  to be an  "environmental
provision" and as such it is expressly  understood  that the Borrower's  duty to
indemnify the Agent and the Lenders hereunder shall survive the termination

or cancellation of the Commitments or this Agreement and the making
and repayment of the Loans.

         10.2.        Governing Law; Consent to Jurisdiction.  THIS AGREEMENT
SHALL BE DEEMED TO HAVE BEEN EXECUTED, DELIVERED AND ACCEPTED IN NORTH CAROLINA
AND SHALL BE INTERPRETED, AND THE RIGHTS AND LIABILITIES OF THE PARTIES HERETO
DETERMINED, IN ACCORDANCE WITH THE INTERNAL LAWS (AS OPPOSED TO CONFLICTS OF LAW
PROVISIONS) OF THE STATE OF NORTH  CAROLINA;  PROVIDED  THAT EACH LETTER OF
CREDIT  SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE LAWS OR RULES  DESIGNATED  IN SUCH  LETTER  OF  CREDIT  OR, IF NO SUCH
LAWS OR RULES ARE DESIGNATED,  THE UNIFORM  CUSTOMS AND  PRACTICES FOR
DOCUMENTARY  CREDITS (1993 REVISION),  INTERNATIONAL CHAMBER OF COMMERCE,
PUBLICATION NO. 500 (THE "UNIFORM CUSTOMS")  AND, AS TO MATTERS NOT GOVERNED
THEREBY,  THE  INTERNAL  LAWS OF THE STATE OF THE DOMICILE OF THE ISSUING BANK.
AS PART OF THE  CONSIDERATION FOR NEW VALUE THIS DAY RECEIVED, THE BORROWER
HEREBY CONSENTS TO THE JURISDICTION OF ANY STATE COURT  WITHIN  MECKLENBURG
COUNTY,  NORTH  CAROLINA OR ANY FEDERAL  COURT LOCATED  WITHIN THE  WESTERN
DISTRICT  OF THE STATE OF NORTH  CAROLINA  FOR ANY PROCEEDING  INSTITUTED
HEREUNDER OR UNDER ANY OF THE OTHER LOAN  DOCUMENTS,  OR ARISING OUT OF OR IN
CONNECTION  WITH THIS  AGREEMENT  OR ANY OF THE OTHER LOAN DOCUMENTS, OR ANY
PROCEEDING TO WHICH THE AGENT, THE ISSUING BANK, ANY LENDER OR THE BORROWER IS A
PARTY, INCLUDING ANY ACTIONS BASED UPON, ARISING OUT OF, OR IN CONNECTION  WITH
ANY COURSE OF CONDUCT,  COURSE OF DEALING,  STATEMENT  (WHETHER ORAL OR WRITTEN)
OR ACTIONS OF THE AGENT,  THE ISSUING  BANK,  ANY LENDER OR THE BORROWER.  THE
BORROWER IRREVOCABLY AGREES TO BE BOUND (SUBJECT TO ANY AVAILABLE RIGHT OF
APPEAL) BY ANY JUDGMENT  RENDERED OR RELIEF GRANTED THEREBY AND FURTHER WAIVES
ANY OBJECTION THAT IT MAY HAVE BASED ON LACK OF  JURISDICTION OR IMPROPER VENUE
OR FORUM  NON  CONVENIENS  TO THE  CONDUCT  OF ANY  SUCH  PROCEEDING.  THE
BORROWER CONSENTS THAT ALL SERVICE OF PROCESS BE MADE BY REGISTERED OR CERTIFIED
MAIL DIRECTED TO BORROWER (ATTENTION:  GENERAL COUNSEL) AT ITS ADDRESS SET FORTH
HEREINBELOW,  AND  SERVICE  SO MADE  SHALL BE  DEEMED TO BE  COMPLETED  UPON THE
EARLIER OF ACTUAL RECEIPT  THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE UNITED
STATES MAILS,  PROPER POSTAGE  PREPAID AND PROPERLY  ADDRESSED.  NOTHING IN THIS
SECTION  SHALL  AFFECT  THE RIGHT TO SERVE  LEGAL  PROCESS  IN ANY OTHER  MANNER
PERMITTED BY LAW OR AFFECT THE RIGHT TO BRING ANY ACTION OR  PROCEEDING  AGAINST
THE BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION.

         10.3.        Arbitration; Remedies.

         (a) Upon  demand  of any party  hereto,  whether  made  before or after
institution  of any  judicial  proceeding,  any  dispute,  claim or  controversy
arising out of,  connected with or relating to this Agreement or any of the Loan
Documents  ("Disputes")  between or among  parties  hereto or  thereto  shall be
resolved by binding  arbitration as provided  herein.  Institution of a judicial
proceeding by a party does not waive the right of that party to


                                                       -94-

<PAGE>



demand arbitration  hereunder.  Disputes may include,  without limitation,  tort
claims,  counterclaims,  claims  brought as class  actions,  claims arising from
documents executed in the future, or claims arising out of or connected with the
transaction  contemplated  by  this  Agreement  or any of  the  Loan  Documents.
Arbitration  shall be conducted  under and governed by the Commercial  Financial
Disputes Arbitration Rules (the "Arbitration Rules") of the American Arbitration
Association  (the "AAA") and Title 9 of the U.S. Code. All arbitration  hearings
shall be conducted in Charlotte,  North Carolina.  The expedited  procedures set
forth in Rule 51 et seq. of the Arbitration  Rules shall be applicable to claims
of less than  $1,000,000.  All applicable  statutes of limitation shall apply to
any  Dispute.  A  judgment  upon the award may be  entered  in any court  having
jurisdiction.  The  panel  from  which all  arbitrators  are  selected  shall be
comprised of licensed  attorneys.  The single arbitrator  selected for expedited
procedure   shall  be  a  retired  judge  from  the  highest  court  of  general
jurisdiction,  state  or  federal,  of the  state  where  the  hearing  will  be
conducted.  Notwithstanding the foregoing,  this arbitration  provision does not
apply to disputes under or related to any interest rate protection agreements.

         (b)  Notwithstanding  the  foregoing,  the Borrower  and the Agent,  on
behalf of the Lenders, agree to preserve, without diminution,  certain remedies,
more particularly  described below, that any party hereto may employ or exercise
freely,  either  alone,  in  conjunction  with or  during a  Dispute;  provided,
however,  that the  Borrower  preserves  its right to seek  injunctive  or other
appropriate judicial relief from a court of competent  jurisdiction with respect
to the foregoing  pending final resolution of the Dispute pursuant to subsection
(a) above. The Agent, on behalf of the Lenders,  shall have the right to proceed
in any court of proper jurisdiction or by self-help to exercise or prosecute the
following remedies, as applicable:  (i) all rights to foreclose against any real
or personal  property or other  security by  exercising  a power of sale granted
under any Loan Documents or under applicable law or by judicial  foreclosure and
sale,  including a proceeding to confirm the sale;  (ii) all rights of self-help
including peaceful occupation of real property and collection of rents,  setoff,
and peaceful  possession of personal  property;  (iii) obtaining  provisional or
ancillary remedies  including  injunctive  relief,  sequestration,  garnishment,
attachment,  appointment  of  receiver  and  filing  an  involuntary  bankruptcy
proceeding;  and (iv) when  applicable,  a judgment by  confession  of judgment.
Preservation  of these  remedies  does not limit the power of any  arbitrator to
grant similar remedies that may be requested by a party in a Dispute.

         The Borrower and the Agent,  on behalf of the Lenders,  agree that they
shall not have a remedy of punitive or  exemplary  damages  against the other in
any Dispute and hereby waive any right or claim to punitive or exemplary damages
they have now or which may


                                                       -95-

arise in the  future in  connection  with any  Dispute  whether  the  Dispute is
resolved by arbitration or judicially.

shall not be effective until received by the Agent.

         All wire  transfers to the Agent shall be sent to First Union  National
Bank of North  Carolina,  ABA Routing  #053000219,  to the credit of First Union
National  Bank  of  North  Carolina,   Charlotte,  North  Carolina,   Attention:
Syndication  Agency  Services,  G/L  #465906,  RC #5007,  RE: HCIA Inc.,  unless
otherwise instructed by the Agent.

         10.5.        Assignments, Participations.

         (a) With the prior consent of the Agent and the Borrower, which consent
shall not be unreasonably withheld,  each Lender may assign to one or more other
Persons  all or a portion  of its rights and  obligations  under this  Agreement
(including,  without  limitation,  all  or a  portion  of its  Commitments,  the
outstanding  Loans  made by it and  the  Note or  Notes  held by it);  provided,
however, that (i) each such assignment shall be of an equal, pro rata percentage
of such Lender's rights and obligations  (including its Commitments)  under each
Facility,  (ii)  except in the case of an  assignment  to an  Affiliate  of such
Lender or a Person that, immediately prior to such assignment, was a Lender, the
amount of the  Commitments of such assigning  Lender being assigned  pursuant to
each such assignment (determined as of the date of the Assignment and Acceptance
with respect to each such assignment)  shall in no event be less than the lesser
of (y) the  aggregate  Commitments  of such  Lender  immediately  prior  to such
assignment or (z) $5,000,000, (iii) each such assignment shall be to an Eligible
Assignee,  and (iv) the parties to each such assignment will execute and deliver
to the Agent,  for its acceptance  and recording in the Register,  an Assignment
and Acceptance,  together with any Note or Notes subject to such assignment, and
will pay a processing fee of $3,000 to the Agent for its own account.  Upon such
execution,  delivery, acceptance and recording of the Assignment and Acceptance,
from and after the effective date specified therein (a) the assignee  thereunder
shall be deemed a party  hereto and,  to the extent that rights and  obligations
hereunder have been assigned to it pursuant to such  Assignment and  Acceptance,
shall have the rights and  obligations  of such Lender  hereunder  with  respect
thereto,  and (b) the  assigning  Lender  shall,  to the extent  that rights and
obligations  hereunder have been assigned by it pursuant to such  Assignment and
Acceptance,  relinquish  its rights and be released from its  obligations  under
this Agreement (and, in the case of an Assignment and Acceptance covering all or
the remaining  portion of such assigning  Lender's rights and obligations  under
this Agreement, such Lender shall cease to be a party hereto).

         (b)          By executing and delivering an Assignment and Acceptance,
the assigning Lender and the assignee thereunder confirm to and agree with each
other, and with the other parties hereto, as follows:  (i) other than as may be
provided in such


                                                       -97-

Assignment and  Acceptance,  such assigning  Lender makes no  representation  or
warranty  and  assumes  no  responsibility   with  respect  to  any  statements,
warranties or  representations  made in or in connection  with this Agreement or
any other Loan Document or the execution,  legality,  validity,  enforceability,
genuineness,  sufficiency  or value of this Agreement or any other Loan Document
or any other instrument or document  furnished hereto or pursuant thereto;  (ii)
such  assigning  Lender  makes no  representation  or  warranty  and  assumes no
responsibility with respect to the financial condition of the Borrower or any of
its  Subsidiaries or the performance or observance by the Borrower or any of its
Subsidiaries of any of their respective  obligations under this Agreement or any
other Loan  Document  or any other  instrument  or document  furnished  pursuant
hereto or thereto;  (iii) such  assignee has received a copy of this  Agreement,
together with copies of the Financial  Statements  and such other  documents and
information  as it has deemed  appropriate  to make its own credit  analysis and
decision to enter into this  Agreement;  (iv) such assignee will,  independently
and without  reliance upon the Agent,  the assigning Lender or any other Lender,
and based on such documents and information as it shall deem  appropriate at the
time,  continue to make its own credit  decisions in taking or not taking action
under this  Agreement;  (v) such  assignee  is an Eligible  Assignee;  (vi) such
assignee  appoints and  authorizes the Agent to take such action as agent on its
behalf and to exercise such powers and  discretion  under this Agreement and the
other Loan Documents and any other instruments and agreements referred to herein
or therein, and to exercise such powers and to perform such duties hereunder and
thereunder,  as are  specifically  delegated  to or required of the Agent by the
terms  hereof or thereof  and such  other  powers as are  reasonably  incidental
thereto; and (vii) such assignee will perform in accordance with their terms all
of the  obligations  that by the  terms of this  Agreement  are  required  to be
performed by it as a Lender.

         (c) The Agent will maintain a copy of each  Assignment  and  Acceptance
delivered to and accepted by it and a register for the  recordation of the names
and addresses of the Lenders and the Commitments of, and principal amount of the
Loans owing to, each Lender from time to time (the  "Register").  The entries in
the Register shall be conclusive and binding for all purposes,  absent  manifest
error,  and the Borrower,  the Agent, the Issuing Bank and the Lenders may treat
each Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this  Agreement.  The Register  shall be available for inspection by
the  Borrower,  the Issuing Bank or any Lender at any  reasonable  time and from
time to time upon reasonable prior notice.

         (d)          Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an assignee, together with any Note or Notes subject
to such assignment, the Agent will, if such Assignment and Acceptance has been
completed and is in substantially the form of Exhibit D, (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the
Register and (iii) give notice thereof to the Borrower.  Within


                                                       -98-

five (5) Business Days after its receipt of such notice, the Borrower,  at their
own  expense,  will  execute  and  deliver  to the  Agent  in  exchange  for the
surrendered  Note or Notes a new Note or Notes to the order of such  assignee in
an amount equal to the Commitment or Commitments  assumed by it pursuant to such
Assignment and Acceptance  and, to the extent the assigning  Lender has retained
its  Commitments  hereunder,  a new Note or Notes to the order of the  assigning
Lender  in an amount  equal to the  Commitment  or  Commitments  retained  by it
hereunder.  Such new Note or Notes  shall be in an  aggregate  principal  amount
equal to the aggregate principal amount of such surrendered Note or Notes, shall
be  dated  the  effective  date of such  Assignment  and  Acceptance  and  shall
otherwise be in substantially the forms of Exhibits A-1 and A-2, as appropriate.

         (e) Each Lender may sell to one or more other Persons participations in
any portion  comprising less than all of its rights and  obligations  under this
Agreement  (including,  without  limitation,  a portion of its Commitments,  the
outstanding  Loans  made by it and  the  Note or  Notes  held by it);  provided,
however,  that (i) such Lender's  obligations  under this Agreement shall remain
unchanged,  (ii) such Lender shall remain solely responsible for the performance
of such  obligations,  (iii) the Borrower,  the Issuing Bank,  the Agent and the
other  Lenders  shall  continue to deal solely and directly  with such Lender in
connection with such Lender's rights and obligations under this Agreement,  (iv)
any such participation shall be in an amount of not less than $3,000,000, (v) no
Lender shall sell any  participation  that,  when taken  together with all other
participations,  if any, sold by such Lender, covers all of such Lender's rights
and obligations under this Agreement (including,  without limitation, all of its
Commitments, the outstanding Loans made by it and the Note or Notes held by it),
(vi) each such  participation  shall be of an equal, pro rata percentage of such
Lender's rights and obligations (including its Commitments) under each Facility,
(vii) no Lender shall permit any  participant  to have any voting  rights or any
right  to  control  the  vote of such  Lender  with  respect  to any  amendment,
modification,  waiver, consent or other action hereunder or under any other Loan
Document  except as to actions of the type  described  in Section  10.8(a),  and
(viii) the  parties to each such  participation  shall pay a  processing  fee of
$3,000 to the Agent for its own  account.  In the case of a  participation,  the
participant  shall not have any rights under this  Agreement or any of the other
Loan Documents,  the participant's rights against the granting Lender in respect
of such participation to be those set forth in the participation  agreement, and
all amounts  payable by the Borrower  hereunder  shall be  determined as if such
Lender  had not sold  such  participation;  provided,  however,  that  each such
participant  shall have the rights of a Lender for purposes of Sections 2.11(a),
2.11(b),  2.12, 2.13 and 8.2, and shall be entitled to the benefits thereto,  to
the extent that the Lender selling such participation  would be entitled to such
benefits if the participation had not been sold.

<PAGE>



         (f) With the prior  consent of the Required  Lenders and the  Borrower,
which consent shall not be  unreasonably  withheld,  the Issuing Bank may assign
all, but not less than all, of its rights and  obligations as Issuing Bank under
this Agreement,  including,  without limitation, its commitment to issue Letters
of Credit, to any Eligible Assignee, and upon acceptance of such assignment, the
successor  Issuing  Bank shall  succeed to such rights and  obligations  and the
assigning Issuing Bank shall be discharged therefrom.

         (g) The Agent, the Issuing Bank and each Lender may, in connection with
any assignment or participation or proposed assignment or participation pursuant
to this Section,  disclose to the assignee or participant,  or proposed assignee
or participant,  any information  relating to the Borrower and its  Subsidiaries
furnished to it by or on behalf of any other party  hereto,  provided  that such
assignee or participant or proposed assignee or participant agrees in writing to
the Agent,  the Issuing  Bank or such  Lender,  as the case may be, to keep such
information  confidential  to the same  extent  required  of the  Lenders  under
Section 10.17.

         10.6.        Fees and Expenses.  Whether or not the transactions
contemplated by this Agreement shall be consummated, the Borrower
shall be obligated:

         (a) to pay or  reimburse  the Agent  upon  demand  and after  notice in
accordance  with Section 10.4 for all reasonable  expenses  (including,  without
limitation,  reasonable  attorneys' fees, but excluding  salaries of the Agent's
regularly  employed  personnel  and  overhead)  incurred or paid by the Agent in
connection  with:  (i) the  preparation,  execution,  delivery,  interpretation,
modification,  amendment  or  termination  of this  Agreement  or the other Loan
Documents  or any  consent or waiver  requested  by the  Borrower  hereunder  or
thereunder; (ii) charges for appraisers,  examiners,  environmental consultants,
auditors or similar  Persons whom the Agent may engage with respect to rendering
opinions   concerning   the   financial   condition  of  the  Borrower  and  its
Subsidiaries;  and (iii) any commercially reasonable attempt to inspect, verify,
protect,  preserve,  collect,  sell,  liquidate  or  otherwise  dispose  of  the
Collateral or any other assets of the Borrower or any Guarantor;

         (b) to pay or reimburse the Agent and each Lender upon demand and after
notice in accordance with Section 10.4 for all reasonable  expenses  (including,
without  limitation,  reasonable  attorneys' fees, but excluding salaries of the
Agent's or such Lender's  regularly employed personnel and overhead) incurred or
paid by the  Agent  or such  Lender  in  connection  with:  (i) any  litigation,
contest, dispute, suit or proceeding or action (whether instituted by the Agent,
the  Lenders,  or any of them,  the  Borrower  or any other  Person)  in any way
relating to this  Agreement or the other Loan  Documents or to the Borrower's or
any  Subsidiary's  affairs  (other  than a dispute  solely  between or among the
Lenders or the  Lenders  and the  Agent);  (ii) any attempt by the Agent or such
Lender to enforce any of its rights against the Borrower or


                                                       -100-

any other  Person that may be obligated to the Agent or such Lender by virtue of
this  Agreement  or the other  Loan  Documents;  and (iii)  any  refinancing  or
restructuring  of the credit  arrangement  provided  under this Agreement in the
nature of a "work-out" or in any insolvency or bankruptcy proceeding;

         (c) to pay and hold the Agent and each Lender harmless from and against
any and all liability and loss with respect to or resulting  from the nonpayment
or  delayed  payment  of any and all  intangibles,  documentary  stamp and other
similar taxes, fees and excises,  if any,  including any interest and penalties,
that may be, or be determined to be, payable in connection with the transactions
contemplated  by  this  Agreement  and  the  other  Loan  Documents  or  in  any
modification hereof or thereof;

         (d) to pay and hold the Agent and each Lender harmless from and against
any and all finder's or brokerage  fees and  commissions  that may be payable in
connection  with the  transactions  contemplated by this Agreement and the other
Loan Documents, other than any fees or commissions of finders or brokers engaged
by the Agent or any Lender, and

         10.7.  Indemnification.  From and at all  times  after the date of this
Agreement,  and in addition to the costs and expenses payable under Section 10.6
and all of the Agent's and the Lenders'  other  rights and remedies  against the
Borrower,  the Borrower  agrees to indemnify  and hold  harmless the Agent,  the
Issuing Bank and each Lender and each of their directors,  officers,  employees,
agents and  Affiliates  (each,  an  "Indemnified  Person")  against  any and all
claims, losses, damages,  liabilities,  costs and expenses of any kind or nature
whatsoever,  including, without limitation,  attorneys' fees, costs and expenses
(collectively,  "Indemnified  Costs")  incurred by or asserted  against any such
Indemnified  Person from and after the date hereof,  whether direct or indirect,
as a result of or arising  from or in any way  relating  to any suit,  action or
proceeding  (including  any inquiry or  investigation)  by any  Person,  whether
threatened  or  initiated,  asserting a claim for any legal or equitable  remedy
under any statute or regulation,  including,  without limitation, any federal or
state  securities laws, or under any common law or equitable cause or otherwise,
arising from or in  connection  with the  negotiation,  preparation,  execution,
performance  or enforcement of this Agreement or the other Loan Documents or any
of the  transactions  contemplated  herein or therein,  and  including,  without
limitation,  Environmental  Claims,  whether or not such Indemnified Person is a
party to any such action,  proceeding  or suit or the target of any such inquiry
or investigation;  provided,  however, that no Indemnified Person shall have the
right to be indemnified  hereunder for any Indemnified Costs resulting primarily
from the gross negligence or willful  misconduct of such Indemnified  Person (as
finally  determined  by  a  court  of  competent  jurisdiction  or  pursuant  to
arbitration  as set forth in Section 10.3).  Without  limiting the generality of
the foregoing,  the Indemnified Costs with respect to Environmental Claims shall
include,  without  limitation,   amounts  paid  in  settlement  of  claims,  all
consultant and expert fees and expenses


                                                       -101-

of any Indemnified  Person incurred in connection with any investigation of site
conditions, any abatement, cleanup, remediation, removal or restoration work, or
liability  for any damages or injuries of any Person or to land,  air,  water or
other  natural  resources.  All of the  foregoing  losses,  damages,  costs  and
expenses of any Indemnified Person shall be payable by the Borrower, as and when
incurred and upon demand, and shall be additional Credit Obligations  hereunder.
In the event that the foregoing indemnity is unavailable or insufficient to hold
each Indemnified  Person harmless,  then the Borrower will contribute to amounts
paid or payable by such Indemnified Persons in respect of their losses,  claims,
damages or liabilities in such proportions as appropriately reflect the relative
benefits  received by and fault of the Borrower and such Indemnified  Persons in
connection  with the  matters  as to  which  such  losses,  claims,  damages  or
liabilities relate and other equitable considerations.

         10.8. Amendments, Waivers, Etc. Except as may be otherwise specifically
set forth in this Agreement or the other Loan Documents,  neither this Agreement
nor any other Loan Document nor any provision  hereof or thereof may be amended,
modified,  waived, discharged or terminated,  and no consent to any departure by
the  Borrower  from any  provision  hereof or thereof may be given,  except in a
writing signed by the Required Lenders; provided, however, that:

         (a) no such amendment,  modification, waiver, discharge, termination or
consent shall,  without the consent of each Lender  holding  Credit  Obligations
directly  affected  thereby,  (i)  reduce  the  principal  amount of, or rate of
interest  on, any Loan,  or reduce any fees or other Credit  Obligations  (other
than fees  payable to the Agent for its own account) or any  obligations  of any
Person now or  hereafter  primarily or  contingently  liable with respect to the
Credit Obligations or (ii) postpone any date fixed for any payment of principal,
interest (other than additional interest payable under Section 2.6(b) during the
continuance of an Event of Default),  fees (other than fees payable to the Agent
for its own account) or any other Credit Obligations;

         (b) no such amendment,  modification, waiver, discharge, termination or
consent shall,  without the consent of all Lenders, (i) increase the Commitments
of any  Lender  (it being  understood  that a waiver of any  Default or Event of
Default or of any  mandatory  reduction  in either  Total  Commitment  shall not
constitute such an increase),  (ii) change the definition of "Required  Lenders"
or otherwise  change the number or  percentage of Lenders that shall be required
for the Lenders or any of them to take or approve,  or direct the Agent to take,
any action  hereunder,  (iii) amend,  modify or waive any of the  provisions for
extending,  or take action to extend,  the term of the Revolving Credit Facility
or Term  Loan  Facility,  (iv)  affect  the  obligation  of the  Lenders  having
Revolving Credit Commitments to become L/C Participants, (v) amend any provision
of this  Section,  (vi) release all or  substantially  all of the  Collateral or
(vii) consent to the  assignment  or transfer by the  Borrower,  or by any other
Person now or  hereafter  primarily or  contingently  liable with respect to the
Credit


                                                       -102-

<PAGE>



Obligations, of any of its rights and obligations under this
Agreement or any of the other Loan Documents;

         (c) no provision  relating to the rights or  obligations of the Issuing
Bank under this  Agreement  or any of the other Loan  Documents  may be amended,
modified or waived without the consent of the Issuing Bank; and

         (d) no  provision  relating to the rights or  obligations  of the Agent
under this Agreement or any of the other Loan Documents may be amended, modified
or waived without the consent of the Agent.

         10.9.        Rights and Remedies Cumulative, Non-Waiver, Etc.  The
enumeration of the Agent's and the Lenders' rights and remedies set forth in
this Agreement and the other Loan Documents is not intended to be exhaustive,
and the exercise by the Agent or any Lender of any right or remedy shall not
preclude the exercise of any other rights or remedies, all of which shall be
cumulative, and shall be in addition to any other right or remedy given
hereunder, under the other Loan Documents or under any other agreement between
the Borrower and the Lenders, or any of them (or the Agent on their behalf), or
that may now or hereafter exist in law or in equity or by suit or otherwise.  No
delay or failure to take action on the part of the Agent or any Lender in
exercising any right, power or privilege shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right, power or privilege
preclude other or further exercise thereof or the exercise of any other right,
power or privilege or shall be construed to be a waiver of any Event of Default.
No course of dealing between any of the Borrower and the Agent or the Lenders or
their agents or employees shall be effective to change, modify or discharge any
provision of this Agreement or to constitute a waiver of any Event of Default.
No notice to or demand upon the Borrower in any case shall entitle the Borrower
to any other or further notice or demand in similar or other circumstances or
constitute a waiver of the right of the Agent or any Lender to exercise any
right or remedy or take any other or further action in any circumstances without
notice or demand.

         10.10. Binding Effect,  Assignment.  All of the terms of this Agreement
shall  be  binding  upon,  inure to the  benefit  of and be  enforceable  by the
respective  successors and assigns of the Borrower,  the Agent, the Issuing Bank
and each Lender;  provided,  however, that (i) the Borrower may not sell, assign
or transfer this Agreement or any portion hereof or thereof, including,  without
limitation,  any of its rights, title,  interests,  remedies,  powers and duties
hereunder or thereunder and (ii) any assignees and  participants  of the Lenders
and any  successor  Issuing  Bank shall have such  rights and  obligations  with
respect to this  Agreement  and the other Loan  Documents as are provided for in
and pursuant to Section 10.5.

<PAGE>



         10.11.       Severability.  To the extent any provision of this
Agreement is prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or
the remaining provisions of this Agreement.

         10.12.   Entire  Agreement.   THIS  AGREEMENT  AND  THE  DOCUMENTS  AND
INSTRUMENTS EXECUTED AND DELIVERED  CONTEMPORANEOUSLY HEREWITH EMBODY THE ENTIRE
AGREEMENT AND  UNDERSTANDING  BETWEEN THE PARTIES HERETO AND SUPERSEDE ALL PRIOR
AGREEMENTS AND UNDERSTANDINGS OF SUCH PERSONS, ORAL OR WRITTEN,  RELATING TO THE
SUBJECT  MATTER HEREOF,  INCLUDING  WITHOUT  LIMITATION  THE COMMITMENT  LETTER,
EXCEPT  FOR THE FEE  LETTER  AND ANY PRIOR  ARRANGEMENTS  MADE WITH  RESPECT  TO
PAYMENT  BY THE  BORROWER  OF (OR ANY  INDEMNIFICATION  FOR) ANY FEES,  COSTS OR
EXPENSES  PAYABLE  TO OR  INCURRED  (OR TO BE  INCURRED)  BY OR ON BEHALF OF THE
AGENT,  THE ISSUING BANK OR ANY LENDER,  THE  PROVISIONS OF WHICH FEE LETTER AND
ANY SUCH PRIOR ARRANGEMENTS ARE HEREBY  INCORPORATED INTO THIS AGREEMENT BY THIS
REFERENCE.  THIS  AGREEMENT,  THE  NOTES,  THE  OTHER  LOAN  DOCUMENTS  AND  THE
INSTRUMENTS AND DOCUMENTS  EXECUTED IN CONNECTION  HEREWITH  REPRESENT THE FINAL
AGREEMENT  BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS  OR  SUBSEQUENT  ORAL  AGREEMENTS  OF THE PARTIES.  THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         10.13.  Interpretation.  The  captions  to  the  various  sections  and
subsections of this Agreement have been inserted for convenience  only and shall
not limit or affect  any of the  terms  hereof.  Unless  the  context  otherwise
requires,  words in the  singular  include  the  plural  and words in the plural
include  the  singular,  and the use of any gender  shall be  applicable  to all
genders.

         10.14.  Counterparts; Effectiveness.  This Agreement may be executed in
any number of counterparts and by different parties hereto on separate
counterparts,  each of which, when so executed and delivered,  shall be an
original,  but all of  which  shall  together  constitute  one and the  same
instrument.  This  Agreement  shall  become  effective  upon the  execution of a
counterpart hereof by each of the parties hereto.

         10.15.  Conflict of Terms.  The Exhibits and  Schedules  hereto and the
other Loan  Documents  are  incorporated  in this  Agreement  by this  reference
thereto.  Except as otherwise provided in this Agreement and except as otherwise
provided  in the  other  Loan  Documents,  if any  provision  contained  in this
Agreement is in conflict with, or inconsistent  with, any provision of the other
Loan Documents, the provision contained in this Agreement shall control.

         10.16.  Injunctive Relief.  The Borrower recognizes that in the event
it fails to perform, observe or discharge any of its obligations or liabilities
under this Agreement, any remedy of law may prove to be inadequate relief to the
Agent and the Lenders.  The Borrower therefore agrees that the Agent and the
Lenders, if the Agent so requests, shall be entitled to temporary and permanent
injunctive


                                                       -104-

<PAGE>



relief  without  the  necessity  of proving  actual  damages in any case where a
remedy at law, in the reasonable good faith opinion of the Required Lenders, may
prove to be inadequate relief.

         10.17.  Confidentiality.   Each  Lender  agrees  to  take  normal  and
reasonable  precautions and exercise due care to maintain the confidentiality of
all  nonpublic  confidential   information  provided  in  connection  with  this
Agreement or any other Loan Document and agrees and undertakes that it shall not
use any such information for any purpose or in any manner other than pursuant to
the  terms  contemplated  by  this  Agreement.  Any  Lender  may  disclose  such
information (i) at the request of any bank regulatory authority or in connection
with an  examination  of such  Lender by any such  authority,  (ii)  pursuant to
subpoena or other court process, (iii) when required to do so in accordance with
the  provisions  of any  applicable  law,  (iv) at the express  direction of any
agency of any State of the United States of America or of any other jurisdiction
in which such Lender  conducts its business or (v) to such Lender's  independent
auditors and other  professional  advisors that have a reasonable  need or basis
for  access  thereto.  The  Lenders  agree to notify  the  Borrower  of any such
disclosure.

         10.18.  Post-Closing Matters.  The Borrower will, and will cause each
of its Subsidiaries to, use its best efforts to assist the Agent in the
syndication of the Facilities and the resultant addition of Lenders after the
Closing Date.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed in their corporate names by their duly authorized corporate officers as
of the date first above written.

                                     (i)    Registration.  If the Company  shall
         determine to register any of its equity  securities  either for its own
         account or for the account of Persons who, by virtue of agreements with
         the  Company,  are  entitled  to  include  their securities in any such

         registration  form  which  does  not permit secondary sales or does not
         include  substantially  the same information as would be required to be
         included  in a  registration statement covering the sale of Registrable
         Securities, the Company will:

                                    (A) promptly give to each of  the Holders  a
              written  notice  thereof  (which  shall  include  a  list  of  the
              jurisdictions  in which the Company intends to attempt to  qualify
              such  securities  under the applicable  blue  sky  or  other state
              securities laws); and

                                    (B) include  in  such  registration (and any
              related qualification under blue sky laws  or  other  compliance),
              and  in any  underwriting  involved therein,  all the  Registrable
              Securities  specified in a written request  or  requests,  made by
              the Holders within fifteen (15) days after receipt of the  written
              notice from the Company  described in clause (i) above,  except as
              set forth in Section  2(a)(ii)  below.  Such  written  request

                                       3

<PAGE>


              may specify all or a part of the  Holders' Registrable Securities.

                           (ii)  Underwriting.  If the registration of which the
         Company gives notice is for a registered  public offering  involving an
         underwriting, the Company shall so advise each of the Holders as a part
         of the written  notice given  pursuant to Section  2(a)(i)(a).  In such
         event,  the right of each of the  Holders to  registration  pursuant to
         this Section 2(a) shall be conditioned upon such Holders' participation
         in such  underwriting  and the inclusion of such  Holders'  Registrable
         Securities  in the  underwriting  to the extent  provided  herein.  The
         Holders  whose  shares are to be  included in such  registration  shall
         (together  with the  Company  and the Other  Stockholders  distributing
         their securities through such underwriting)  enter into an underwriting
         agreement in customary form with the  representative of the underwriter
         or   underwriters   selected   for   underwriting   by   the   Company.
         Notwithstanding  any  other  provision  of this  Section  2(a),  if the
         representative  determines that marketing  factors require a limitation
         on the  number of shares to be  underwritten,  the  representative  may
         (subject to the  allocation  priority set forth below) limit the number
         of  Registrable  Securities  to be  included  in the  registration  and
         underwriting.  The Company  shall so advise all  holders of  securities
         requesting  registration,  and the number of shares of securities  that
         are entitled to be included in the registration and underwriting  shall
         be allocated in the  following  manner:  The  securities of the Company
         held by  officers,  directors  and Other  Stockholders  of the  Company
         (other than  Registrable  Securities and other than  securities held by
         holders who by contractual right demanded such  registration)  shall be
         excluded from such registration and underwriting to the extent required
         by such  limitation,  and, if a  limitation  on the number of shares is
         still  required,  the  number of  shares  that may be  included  in the
         registration  and underwriting by each of the Holders shall be reduced,
         on a pro  rata  basis  (based  on the  number  of  shares  held by such
         Holder),  by such  minimum  number of shares as is  necessary to comply
         with such limitation. If any of the Holders or any officer, director or
         Other Stockholder disapproves of the terms of any such underwriting, he
         may elect to withdraw  therefrom  by written  notice to the Company and
         the  underwriter.   Any  Registrable  Securities  or  other  securities
         excluded or withdrawn  from such  underwriting  shall be withdrawn from
         such registration.

                                     (b)  Shelf Registration;  Suspension of Use
         of Prospectus.

                           (i) Not later than the Filing Date, the Company shall
         prepare and file with the  Commission  a Shelf  Registration  Statement
         relating  to the offer and sale of the  Registrable  Securities  by the
         Holders  from  time  to  time  in

                                       4

<PAGE>

         accordance with the methods of distribution elected by such Holders and
         set forth in such Shelf Registration Statement.   The Company shall use
         its best efforts to have the  Shelf   Registration  Statement  declared
         effective  under  the Securities  Act not later than 60 days  following
         the  Filing  Date (the date the  Shelf  Registration  Statement  is  so
         declared  effective  is  hereinafter  referred  to as the "Registration
         Date").

                           (ii) The Company  shall use its best  efforts to keep
         the Shelf  Registration  Statement  continuously  effective in order to
         permit  the  Prospectus  forming  part  thereof to be usable by Holders
         until the  earlier of (A) the date after  which all of the  Registrable
         Securities  may be sold  pursuant to Rule 144(k)  under the  Securities
         Act, (B) the second  anniversary  of the  Registration  Date or (C) the
         date  when  all  the  Registrable   Securities  covered  by  the  Shelf
         Registration   Statement   have  been  sold   pursuant   to  the  Shelf
         Registration  Statement (in any such case, such period being called the
         "Shelf Registration Period").

                           (iii) The Company  shall not be  obligated  to effect
         any  registration  pursuant  to this  Section  2(b)  in any  particular
         jurisdiction  in which  the  Company  would be  required  to  execute a
         general  consent to service of process in effecting such  registration,
         qualification  or compliance,  unless the Company is already subject to
         service  in such  jurisdiction  and  except as may be  required  by the
         Securities Act or applicable rules or regulations thereunder.

                           (c)  Expenses  of  Registration.   All   Registration
Expenses  incurred  in  connection  with   any  registration,  qualification  or
compliance  pursuant to this Section 2  shall  be borne by the Company,  and all
Selling Expenses shall be borne by the Holders of the  securities  so registered
pro rata on the basis of the number of their shares so registered.

                           (d)  Registration Procedures.  In the  case of each
registration effected by the  Company  pursuant  to this  Section 2, the Company
will keep the  Holders advised in  writing as to the initiation of each
registration and as to the completion thereof. At its expense, the Company will:

                           (i)  keep such registration effective for a period
         of  one hundred  twenty (120) days (or,  in the case of a Shelf
         Registration Statement, for the Shelf Registration Period) or until the
         Holders,  as applicable,  have completed  the distribution described in
         the  registration  statement relating thereto,  whichever first occurs;
         provided, however, that the Shelf Registration Period shall be extended
         for  a  period  of  time equal to the  period  during  which use of the
         Prospectus is suspended in accordance  with provisions of  Section 2(j)
         hereof; and

                                       5

<PAGE>

                           (ii)  furnish  such  number of prospectuses and other
         documents incident thereto as each of the Holders  from  time to time
         may reasonably request.

                           (e)  Indemnification.

                           (i)  The Company will indemnify each of the Holders,
         each of its officers, directors  and partners, and each person
         controlling  each  of the Holders,  with  respect to each  registration
         which  has  been  effected   pursuant  to  this  Section  2,  and  each
         underwriter,  if any,  and each person who  controls  any  underwriter,
         against  all  claims,  losses, damages and liabilities (or  actions  in
         respect  thereof) arising out of or based on any untrue  statement  (or
         alleged  untrue  statement)  of  a  material  fact  contained  in   any
         prospectus, offering  circular or other document (including any related
         registration statement, notification or the like) incident  to any such
         registration and related  qualification or compliance,  or based on any
         omission  (or  alleged  omission)  to  state  therein  a  material fact
         required  to  be  stated  therein  or  necessary to make the statements
         therein  not  misleading,  or  any  violation  by  the  Company  of the
         Securities Act or the Exchange Act or any rule or regulation thereunder
         applicable to the Company and relating to action or  inaction  required
         of the Company  in  connection  with  any such registration and related
         qualification or compliance,  and  will reimburse  each of the Holders,
         each  of  its  officers,  directors  and  partners,  and  each   person
         controlling each of the Holders,  each such underwriter and each person
         who controls any such underwriter, for any legal and any other expenses
         reasonably incurred in connection  with investigating and defending any
         such  claim,  loss,  damage,  liability  or  action, provided  that the
         Company will not be liable in any such case to the extent that any such
         claim, loss,  damage,  liability or expense arises out of or  is  based
         on any untrue  statement  or  omission  based upon written  information
         furnished  to the Company by the Holders or underwriter in  writing and
         stated to be specifically for use therein.

                           (ii)  Each   of   the   Holders   will,  if
         Registrable Securities held by it are included in the  securities as to
         which  such  registration  and  related  qualification or compliance is
         being  effected,  indemnify  the  Company,  each  of  its directors and

<PAGE>

         such  Holder, or any omission (or alleged omission) to state therein  a
         material  fact  required  to be stated therein or necessary to make the
         statements by  such Holder therein  not misleading,  and will reimburse
         the Company and such Other Stockholders, directors, officers, partners,
         persons,  underwriters  or  control  persons for any legal or any other
         expenses  reasonably  incurred  in  connection  with  investigating  or

         to the net proceeds to such Holder of  securities  sold as contemplated
         herein.

                                     (iii)     Each     party     entitled    to
         indemnification under this Section 2(e) (the "Indemnified Party") shall
         give  notice  to  the  party required to provide indemnification   (the
         "Indemnifying   Party")  promptly  after  such  Indemnified  Party  has
         actual  knowledge  of any  claim  as to  which indemnity may be sought,
         and  shall permit the  Indemnifying  Party to  assume  the  defense  of
         any  such  claim  or any litigation  resulting therefrom; provided that
         counsel for the Indemnifying Party, who  shall conduct the  defense  of
         such claim or any  litigation   resulting therefrom,  shall be approved
         by  the  Indemnified  Party (whose approval shall not  unreasonably  be
         withheld)  and the  Indemnified  Party may participate in such  defense
         at its own expense  (unless the Indemnified Party shall have reasonably
         concluded  that  there  may  be  a  conflict  of  interest  between the
         Indemnifying  Party and the Indemnified  Party in such action, in which
         case  the  fees  and expenses of such counsel to the Indemnified  Party
         shall  be  at  the  expense  of  the Indemnifying  Party), and provided
         further  that  the  failure of any Indemnified  Party to give notice as
         provided  herein  shall  not  relieve  the  Indemnifying  Party  of its
         obligations  under  this  Section  2  unless the Indemnifying  Party is
         materially prejudiced thereby. No Indemnifying Party, in the defense of
         any such claim or  litigation  shall,  except  with the consent of each
         Indemnified  Party,  consent to entry of any judgment or enter into any
         settlement which does not include as an unconditional  term thereof the
         giving by the  claimant or  plaintiff  to such  Indemnified  Party of a
         release from all liability in respect to such claim or litigation. Each
         Indemnified  Party shall furnish such  information  regarding itself or
         the claim in question as an Indemnifying  Party may reasonably  request
         in writing and as shall be reasonably  required in connection  with the
         defense of such claim and litigation resulting therefrom.

                                     (iv)  If  the  indemnification provided for
         in this Section 2(e) is held by a court of competent jurisdiction to be
         unavailable  to  an  Indemnified  Party  with  respect  to  any   loss,
         liability,  claim,  damage or expense referred  to  herein,   then  the
         Indemnifying   Party,  in  lieu  of indemnifying such Indemnified Party
         hereunder,  shall  contribute  to  the  amount  paid or payable by such
         Indemnified  Party as a result of such loss,  liability,  claim, damage
         or  expense  in  such  proportion  as  is  appropriate  to  reflect the
         relative  fault  of  the Indemnifying  Party on the one hand and of the
         Indemnified  Party on the other in  connection with  the  statements or
         omissions   which  resulted  in  such  loss, liability,  claim,  damage
         or  expense,  as well as any other  relevant equitable  considerations.
         The  relative  fault  of  the Indemnifying Party and of the Indemnified
         Party shall be determined by reference to, among other  things, whether
         the  untrue (or  alleged  untrue)  statement  of a material fact or the
         omission (or  alleged  omission)  to  state  a material fact relates to
         information  supplied by the  Indemnifying  Party or by the Indemnified
         Party   and   the  parties'   relative  intent,   knowledge,  access to
         information  and  opportunity  to correct or  prevent such statement or
         omission.

                                     (v)  Notwithstanding the foregoing, to  the
         extent  that  the  provisions  on  indemnification   and   contribution
         contained  in  the  underwriting agreement  entered  into in connection
         with any  underwritten  public offering  contemplated by this Agreement
         are  in  conflict  with  the foregoing  provisions,  the  provisions in
         such  underwriting  agreement shall be controlling.

                                     (vi)  The foregoing indemnity agreement  of
         the Company and Holders is subject to the  condition  that,  insofar as
         they  relate  to  any  loss,  claim,  liability  or  damage  made  in a
         preliminary   prospectus  but  eliminated  or  remedied  in the amended
         prospectus  on  file  with the  Commission at the time the registration
         statement  in  question  becomes  effective or  the amended  prospectus
         filed  with  the   Commission   pursuant to Commission Rule 424(b) (the
         "Final  Prospectus"),  such indemnity or  contribution agreement  shall
         not  inure  to  the  benefit of any  underwriter if a copy of the Final
         Prospectus was furnished to the  underwriter  and was not furnished  to
         the person asserting the loss, liability,  claim or damage at or  prior
         to the time such action is required by the Securities Act.

                           (f)  Information by the Holders.  Each of the Holders
holding  securities  included  in any registration  shall furnish to the Company
such  information  regarding such Holder  and  the distribution proposed by such
Holder as  the  Company  may  reasonably  request  in writing  and  as  shall be
reasonably  required  in  connection  with  any  registration,  qualification or
compliance  referred to in this Section 2.

                           (g)  Rule 144 Reporting.

                  With a view to making  available the benefits of certain rules
and  regulations  of the  Commission  which may  permit  the sale of  restricted
securities to the public without registration, the Company agrees to:

                           (i) make and keep  public  information  available  as
         those terms are understood and defined in Rule 144 under the Securities
         Act ("Rule 144"), at all times from and after the date hereof;

                           (ii)  use its best efforts to file with the
         Commission in a timely manner all reports  and other documents required
         of  the  Company  under  the Securities Act and the Exchange Act at any
         time  after it has become subject to such reporting requirements; and

                           (iii)  so  long  as  the  Holder  owns  any
         Registrable Securities, furnish to the Holder  upon  request, a written
         statement  by  the  Company  as  to its compliance  with the  reporting
         requirements  of Rule 144,  and of the Securities  Act and the Exchange
         Act,  a  copy  of  the most recent annual or  quarterly  report  of the
         Company,  and  such  other  reports  and  documents  so  filed  as  the
         Holder  may  reasonably  request in  availing  itself  of  any  rule or
         regulation  of  the  Commission   allowing  the Holder to sell any such
         securities without registration.

                           (i)  Listing of Common  Stock.  The Company will use
its best efforts to list,  subject to official notice of issuance,  the Common
Stock to be  delivered to the Stockholders on the Nasdaq National Market System
on  or  prior  to  the  date  the  Shelf  Registration Statement becomes
effective.

                           (j)  Notice of Proposed Sale.  If any Holder  desires
to sell or otherwise transfer any of its Registrable Securities  pursuant to the
Shelf Registration  Statement in accordance  with this  Agreement,  such  Holder
shall  notify  the  Company  of  its  intention  to do so by written notice (the
"Notice")  received by the Company at least two business days prior to such sale
or transfer.  Such  Holder may  effect such  sale or transfer  within 20 days of
the delivery of such Notice unless, at least one business day prior thereto, the
Company shall furnish to such Holder a written  notice  stating that, either (i)
in  the  good  faith  judgment  of the Company's  General  Counsel or  principal
outside  legal  counsel,  the sale or transfer  of  the  Registrable  Securities
described in the Notice would, at such time, require the disclosure of  material
information that the Company has a bona fide  business  purpose  for  preserving
as  confidential  or the Company  would require  the  provision  of  information
required by the Commission or the Securities Act (or the  rules  and regulations
promulgated  thereunder),  such as pro

                                       9

<PAGE>

forma  financial  information,  that  at  such  time the Company would be unable
to provide or (ii) the Company has determined to engage in a public  offering of
its common equity  securities (an "Offering") and has been advised in writing by
a nationally recognized investment banking firm selected by the Company that, in
such firm's  opinion,  the sale of the Registrable  Securities  described in the
Notice pursuant to the Shelf  Registration  Statement would adversely affect the
Company's  immediately planned Offering. In such event, the Company's obligation
to prepare a prospectus to be used in connection with the sale or transfer or to
amend the Shelf  Registration  Statement  shall be  suspended  for a  reasonable
period  (but not in excess of 60 days) until the  Company  determines  that such
confidential  information  may be  disclosed  or is able  to  provide  any  such
information  required by the  Commission or the Securities Act (or the rules and
regulations  promulgated  thereunder) or that the sale of Registrable Securities
will not adversely affect the Offering,  as the case may be; provided,  however,
that the Company may only suspend its  obligation  once in any 12-month  period.
Each of the Company and each Holder agrees to keep confidential any notification
by any party  pursuant  to this  Section  2(j).  Each  Holder  agrees  that,  in
connection with any sale or transfer of any Registrable Securities,  such Holder
will  comply  with any  legal  requirement  such  Holder  may have to  deliver a
prospectus. Each Holder also agrees not to offer or sell any of such Registrable
Securities  in any  offering or sale that would  require the Company to amend or
supplement  the prospectus  prepared  pursuant to this Section 2 solely due to a
change in description of the plan of distribution of such Registrable Securities
contained in such prospectus.

                           3. ACKNOWLEDGMENT OF RESTRICTED NATURE OF REGISTRABLE
                              SECURITIES.

                           Each  Stockholder  hereby   acknowledges   that   the
Registrable Securities are subject to the following:

                           (a)      No Stockholder may, directly  or indirectly,
offer, sell, transfer, assign, pledge,  hypothecate or otherwise  dispose of the
Registrable Securities (or solicit any offers to purchase or otherwise   acquire
or take a pledge of such Registrable  Securities),  except  (A)  pursuant  to an
effective  registration statement  under the  Securities Act and the  rules  and
regulations  promulgated  thereunder,  (B)  Rule  144  of the Commission (or any
similar rule or rules then in force  ("Rule  144"))  if such  rule is  available
and (C) any other legally available means of transfer; provided,  however,  that
in  the  case  of  this clause (C) only and at the Company's written request and
expenses  (including,  without  limitation,  reasonable  fees  and  expenses  of
counsel),  the  Holder  thereof  shall  deliver  written  notice to the  Company
describing  in  reasonable  detail  the  transfer or proposed transfer, together
with an opinion  of counsel  which (to the Company's reasonable satisfaction) is
knowledgeable in securities law matters to the effect that such

                                       10

<PAGE>

transfer of Registrable  Securities may be effected without registration of such
Registrable Securities under the Securities Act;

                           (b)    Although the Company will use its best efforts
to  cause  the  Shelf  Registration  Statement to become effective in accordance
with this Agreement,  (A) the offer and sale of Registrable Securities have  not
been  registered  under  the  Securities  Act  or  registered or qualified under
any  "Blue  Sky"  state  securities  laws  as  of  the  date hereof and will not
be  registered  or  qualified  under  the Securities Act or any "Blue Sky" state
securities laws at the Effective Time of the Merger, (B) each  Stockholder  must
continue  to  bear  the  economic  risk  of  the  investment  in its  shares  of
Registrable  Securities  until the offer and sale of such Registrable Securities
are subsequently  registered  and/or qualified under the Securities Act and  any
applicable  "Blue Sky" state  securities laws  pursuant  to this Agreement or an
exemption from such  registration  and/or  qualification is available, (C) there
can be no assurance that the  offer  and sale of such Stockholder's  Registrable
Securities will be registered and/or qualified under the  Securities Act  or any
applicable  "Blue Sky" state  securities  laws at any time, (D) when and if such
Stockholder's  Registrable Securities may be disposed of without registration in
reliance  upon  Rule  144, the offer and sale of such Stockholder's  Registrable
Securities  may  not  qualify  under  Rule 144  since  dispositions  under  such
Rule  can  be  made  only  in  limited  amounts in accordance with the terms and
conditions  of such  Rule,  (E)  if  the  exemption  afforded by Rule 144 is not
available,  public   offer  or  sale  of  the   Registrable  Securities  without
registration willrequire the  availability  of an exemption under the Securities
Act, (F) a restrictive  legend in substantially  the  form hereinafter set forth
shall be placed upon the  Registrable  Securities,  and (G) a notation shall  be
made in the appropriate records of the  Company indicating  that the Registrable
Securities are subject to restrictions on transfer and appropriate stop-transfer
instructions will be issued to the transfer agent of the Company with respect to
the Registrable Securities;

                           (c)     If any Registrable Securities are disposed of
in accordance with Rule 144, the Holder shall deliver to the Company at or prior
to the time of such  disposition an  executed  copy  of  Form  144  (if required
by  Rule  144)  and  such  other  documentation  as  the Company may  reasonably
require in  connection  with such disposition; and

                           (d)      The  Registrable  Securities  shall  bear  a
legend in substantially the following form:

                  THE  SHARES   REPRESENTED   HEREBY  HAVE  BEEN   ACQUIRED  FOR
                  INVESTMENT AND HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES
                  ACT OF 1933 (THE "ACT"). SUCH SHARES MAY NOT BE OFFERED,  SOLD
                  OR OTHERWISE  TRANSFERRED,  PLEDGED OR

                  HYPOTHECATED UNLESS AND UNTIL  REGISTERED  UNDER  THE  ACT AND
                  ANY  APPLICABLE  STATE  SECURITIES  LAWS  OR  PURSUANT  TO  AN
                  EXEMPTION  THEREFROM  UNDER SAID  ACT  AND SUCH LAWS  AND  THE
                  RESPECTIVE   RULES  AND REGULATIONS  THEREUNDER.  THE TRANSFER
                  OF THESE SHARES IS ALSO SUBJECT  TO CERTAIN  RESTRICTIONS  SET

                  9, 1996, A COPY OF WHICH IS AVAILABLE FOR  INSPECTION  AT  THE
                  OFFICES OF HCIA INC.,  300 EAST  LOMABARD  STREET,  BALTIMORE,

                  AND  NO  TRANSFER  OF  THE  SHARES SHALL BE VALID OR EFFECTIVE
                  UNLESS AND UNTIL THE TERMS AND CONDITIONS OF SUCH REGISTRATION
                  IGHTS  AGREEMENT  SHALL HAVE BEEN COMPLIED WITH IN FULL.

                           4.       REPRESENTATIONS BY STOCKHOLDERS.

</TABLE>


(1) As of June 30, 1996, options to purchase 692,306 shares of common stock were
outstanding.  In the calculation of primary net income per share,  these options
were  included  in the average  number of common  shares  outstanding  using the
treasury  stock  method  based on the average  price of the common stock for the
period.

As the price of the Company's common stock on June 30, 1996 was in excess of the
average price for the six months ended June 30, 1996,  the number of shares used
to calculate net income per share on a fully diluted basis is increased as using
the treasury stock method with the period end price result in a higher number of
shares deemed outstanding.

As the Company had a loss for the three months  ended June 30,  1996,  the fully
diluted earnings per share is not applicable.

(2) In accordance with Accounting  Principle Board Opinion No. 15, any reduction
of less than 3% need not be considered dilutive.  Accordingly,  the consolidated
statements of operations  reflect net income per share and the weighted  average
number of shares used in the calculation on a primary basis only.
