                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and consolidated financial statements and notes thereto appearing
elsewhere in this Prospectus.
 
                                  THE COMPANY
 
  Hanger Orthopedic Group, Inc. is a professional practice management company
focused on the orthotic and prosthetic ("O&P") segment of the orthopedic
rehabilitation industry. The Company acquires and operates the practices of
orthotists and prosthetists, medical professionals who design, fabricate, fit
and supervise the use of external musculoskeletal support devices and
artificial limbs. The Company has acquired over 60 O&P businesses since 1986
and currently employs 280 certified O&P practitioners and owns and operates 240
O&P patient-care centers in 30 states and the District of Columbia. The Company
has also developed OPNET, Inc. ("OPNET"), a national preferred provider network
of O&P service professionals. OPNET has contractual relationships with 358 O&P
patient-care centers (240 of which are owned and operated by the Company),
serving 291 managed care plans. In addition to its practice management and
patient-care services, the Company manufactures custom-made and prefabricated
O&P devices and is the largest distributor of O&P components and finished O&P
patient-care products in the United States. The combination of practice
management and patient-care services, OPNET, distribution and manufacturing
operations positions the Company as a fully-integrated provider of O&P
services.
 
  The Company has been an active acquiror of O&P practices since 1986. In 1995,
the Company launched its OPNET network and, on November 1, 1996, acquired J.E.
Hanger, Inc. of Georgia ("JEH"), an O&P provider with 96 patient-care centers
in 15 states and the largest O&P distribution business in the United States.
The acquisition essentially doubled the Company's number of patient-care
centers and certified practitioners and significantly expanded its distribution
capabilities. Since January 1, 1998, the Company has acquired the assets of
five additional O&P companies, representing an aggregate of 25 patient-care
centers and 33 certified practitioners.
 
  The Company estimates that the O&P patient-care services industry in the
United States represented approximately $2.3 billion in sales in 1997. Key
trends expected to increase the demand for O&P services include: (i) the
growing elderly population; (ii) more active lifestyles and emphasis on
physical fitness; (iii) cost savings achieved through the use of outpatient O&P
treatments to reduce hospitalization; (iv) advancing technologies in the design
and manufacture of O&P devices; and (v) the inherent need for replacement of
O&P devices and continuing care.
 
  The O&P services market is highly fragmented and relatively underpenetrated
by professional practice management companies. Hanger is one of the two largest
companies in the O&P industry which, combined, accounted for less than 15% of
the total estimated O&P industry revenue in 1997. There are an estimated 3,300
certified prosthetists and/or orthotists and approximately 2,850 O&P patient-
care centers in the United States. The Company believes that the O&P industry
will continue to consolidate as a result of a variety of factors, including:
(i) increased pressures from growth in managed care; (ii) demonstrated benefits
from economies of scale; and (iii) desire by independent orthotists and
prosthetists to obtain financial liquidity and concentrate on providing patient
care.
 
  The Company's objective is to build a major national orthopedic
rehabilitation company focused on the acquisition and operation of O&P
practices and the manufacturing and distribution of O&P products. The Company's
strategy for achieving this objective is to: (i) acquire and integrate O&P
practices in targeted geographic areas across the United States; (ii) develop
new O&P patient-care centers in existing markets; (iii) expand and improve O&P
practice management operations at existing and acquired patient-care centers;
(iv) increase OPNET's number of O&P patient-care service members and
contractual relationships with managed care organizations; and (v) leverage and
expand the Company's O&P manufacturing and distribution operations.

    this offering upon the sale by the Company of 2,400,000 shares of Common
    Stock offered hereby at an assumed public offering price of $20.13, as if
    all such transactions had occurred on January 1, 1997. See "Use of

(2) Adjusted to give effect to: (i) acquisitions which occurred during the
    five months ended May 31, 1998; and (ii) the reduction in interest expense
    resulting from the application of the estimated net proceeds of this
    offering upon the sale by the Company of 2,400,000 shares of Common Stock

(3) During the fourth quarter of 1997, the Company adopted the provisions of
    Statement of Financial Accounting Standard ("SFAS") 128 and, as required,
    has restated all prior period per common share data. Diluted net income
    per common share amounts are computed using the weighted average number of
    common shares outstanding during the period and dilutive potential common
    shares. Dilutive potential common shares consist of stock options and
    stock warrants and are calculated using the treasury stock method. Diluted
    net income per common share amounts have been adjusted for preferred stock
    dividends.
(4) Adjusted to give effect to acquisitions which occurred during the five
    months ended May 31, 1998. See "Selected Unaudited Pro Forma Condensed
    Consolidated Financial Information."
(5) Adjusted to give effect to the sale by the Company of 2,400,000 shares of
    Common Stock offered hereby at an assumed public offering price of $20.13
    and the application of the estimated net proceeds therefrom. See "Use of
    Proceeds."
(6) Numbers of patient-care centers, certified practitioners and states are
    determined as of period end.
(7) "EBITDA" is defined as net income (loss) before interest expense, taxes,
    depreciation and amortization, discontinued operations, non-recurring
    charges, extraordinary item and accounting change. EBITDA is not a measure
    of performance under GAAP. While EBITDA should not be considered in
    isolation or as a substitute for net income, cash flows from operating
    activities and other income or cash flow statement data prepared in
    accordance with GAAP, or as a measure of profitability or liquidity,
    management understands that EBITDA is customarily used as a criteria in
    evaluating health care companies. Moreover, substantially all of the
    Company's financing agreements contain covenants in which EBITDA is used
    as a measure of financial performance. EBITDA margin is defined as EBITDA
    as a percent of net sales. See "Management's Discussion and Analysis of
    Financial Condition and Results of Operations" for a discussion of
    measures of performance determined in accordance with GAAP.
(8) Operating margin is defined as net income (loss) before interest expense,
    taxes, discontinued operations, non-recurring charges, extraordinary item
    and accounting change as a percent of net sales.
(9) Payor mix data for the years ended December 31, 1996 and 1997 and for the
    quarters ended March 31, 1997 and 1998 is based on a sampling of
    approximately 75% of the patient-care centers in each such period. Payor
    mix data is not available for the years ended December 31, 1993 and 1994.

                                 RISK FACTORS
 
  In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in shares
of the Common Stock offered by this Prospectus. This discussion also
identifies important cautionary factors that could cause the Company's actual
results to differ materially from those described in forward-looking
statements made in this Prospectus, including those regarding the acquisition
of additional patient-care centers and related businesses, the adequacy of the
Company's capital resources and other statements regarding trends. These
forward-looking statements could be affected by a number of risks and
uncertainties including those described below.
 
RISKS ASSOCIATED WITH ACQUISITION STRATEGY
 
  The Company's business strategy contemplates the continued acquisition and
integration of O&P businesses. The success of the Company's acquisitions will
be determined by numerous factors, including the Company's ability to identify
O&P patient-care practices and other O&P businesses suitable for acquisition,
to acquire and finance such businesses on acceptable terms and to integrate
and operate such businesses profitably after acquisition. No assurance can be
given that future acquisitions by the Company will be successfully consummated
and integrated or that such acquisitions will favorably affect the Company's
business or operations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources" and
"Business--Acquisitions."
 
ADDITIONAL FINANCINGS
 
  The Company's acquisition program requires substantial capital resources. No
assurance can be given that the Company's available bank facility and other
sources of capital will be sufficient to provide for the Company's cash
requirements for future acquisitions. The Company may issue additional debt or
equity securities in connection with the acquisition of additional O&P
patient-care centers. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources" and
"Business--Acquisitions."
 
RAPID GROWTH
 
  The Company has pursued, and plans to continue to pursue, an aggressive
growth strategy. The rapid growth may place significant demands on the
Company's financial and managerial resources. There can be no assurance that
the Company will be able to manage this growth effectively. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources" and "Business."
 
REIMBURSEMENT LIMITATIONS
 
  Approximately 62.0% and 52.0% of the Company's net sales in 1997 and the
first quarter of 1998, respectively (based on a sampling of approximately 75%
of the patient-care centers in both periods), were derived from Medicare,
Medicaid, the United States Veterans Administration (the "VA") and certain
state agencies, each of which sets maximum reimbursement levels for O&P
services and products. No assurance can be given that reimbursement levels
under such programs will not be lowered in the future or that the percentage
of the Company's net sales derived from sources limiting reimbursement levels
will not increase. Furthermore, the health care industry is experiencing a
trend towards cost containment as government and other third-party payors seek
to impose lower reimbursement rates and negotiate reduced contract rates with
service providers, which may adversely affect the Company's financial
condition or results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Other" and "Business--
Patient Reimbursement Sources."
 
RETENTION OF KEY PERSONNEL
 
  The success of the Company will depend in part on its continued ability to
retain Ivan R. Sabel, Chairman of the Board, President and Chief Executive
Officer of the Company, qualified O&P practitioners and other managerial and
technical personnel. There can be no assurance that the Company will be able
to continue to retain all of the personnel necessary for continued growth. The
loss of the services of key personnel could have a material adverse effect on
the Company. See "Management."
 
                                       8
<PAGE>
 
VARIABILITY OF QUARTERLY OPERATING RESULTS
 
  The Company's operating results have varied from quarter to quarter and may
continue to vary. Quarterly variations may result from, among other things,
the non-recurring costs associated with the acquisition of O&P patient-care
centers and seasonal factors. The Company's operating results for any
particular quarter may not be indicative of results for future periods.
 
POTENTIAL LIABILITY AND INSURANCE
 
  The provision of O&P services and products, as is the case with other health
care services and products, involves an inherent risk of liability that could
have a material adverse effect on the Company. No assurance can be given that
insurance coverage will continue to be available at commercially reasonable
prices or that such insurance will cover actual future liabilities.
 
POTENTIAL ADVERSE CONSEQUENCES FROM CHANGE IN MANAGEMENT INFORMATION SYSTEMS
 
  The Company plans to upgrade its management information systems sometime
during late 1998 and early 1999. The systems that will be upgraded include the
systems utilized in the Company's corporate headquarters and patient-care
centers for billing purposes. The Company believes that it may experience some
disruptions, including possible increases in accounts receivable due to
billing delays, in connection with the transition from the existing systems to
the new systems. The Company expects to run parallel systems until management
is confident that the new systems are fully functional. The Company has hired
a Director of Information Systems to oversee the transition.
 
GOVERNMENT REGULATION
 
  Most states do not require separate licensure for O&P practitioners.
However, several states currently require practitioners to be certified by an
organization such as the American Board for Certification in Orthotics and
Prosthetics (the "ABC"). While the Company endeavors to comply with all state
licensure requirements, no assurance can be given that the Company will be in
compliance at all times with these requirements. The Company is subject to
various federal and state laws pertaining to health care fraud and abuse,
including antikickback laws, false claims laws and physician self-referral
laws. Antikickback laws make it illegal to solicit, offer, receive, or pay any
remuneration in exchange for, or to induce, the referral of business. False
claims laws prohibit anyone from knowingly and willfully presenting claims for
payment that contain false or fraudulent information. Physician self-referral
laws restrict the ability of a physician to refer patients to entities with
which the physician has a financial relationship, as well as the ability of an
entity to claim reimbursement for services furnished pursuant to a prohibited
referral. Violations of these laws are punishable by criminal and/or civil
sanctions, including, in some instances, imprisonment and exclusion from
participation in federal health care programs, including Medicare, Medicaid,
VA health programs and the Civilian Health and Medical Program for the
Uniformed Services ("CHAMPUS"). There can be no assurance that one or more of
the Company's practices will not be challenged by governmental authorities
under certain of these laws, that the Company would not be required to alter
its practices as a result, or that the occurrence of one or more of these
events would not result in a material adverse effect on the Company's
financial condition and results of operations. The Company is subject to
federal and state antitrust laws which prohibit, among other things, the
establishment of ventures that result in certain anticompetitive conduct.
These laws have been applied to the establishment of certain networks of
otherwise competing health care providers. There can be no assurance that
governmental authorities would not bring an investigation or proceeding
challenging this or some other aspect of the Company's operations under these
laws, or that such an investigation or proceeding would not result in a
material adverse effect on the Company's financial condition and results of
operations. See "Business--Government Regulation."
 
COMPETITION
 
  The business of providing O&P patient-care services is highly competitive.
In addition to many local O&P practices, there are several regional and multi-
regional competitors which operate numerous patient-care centers. The
competition among O&P patient-care centers is primarily for referrals from
physicians, therapists, employers, health maintenance organizations ("HMOs"),
preferred provider organizations ("PPOs"), hospitals,
 
                                       9
<PAGE>
 
rehabilitation centers, outpatient clinics and insurance companies on both a
local and regional basis. Hanger also competes with other providers of O&P
services such as hospitals, physicians and therapists. In connection with its
efforts to acquire additional O&P patient-care practices, the Company
encounters competition from several other companies. The Company also
encounters competition from other manufacturers of non-customized O&P
components. Finally, although the Company is the country's largest distributor
of O&P products, a majority of which are manufactured by other companies,
Hanger encounters competition from numerous smaller companies engaged in the
distribution of O&P products. There can be no assurance that levels of
competition will not increase or that such competition will not have a
material adverse effect on the Company's O&P patient-care services,
manufacturing or distribution activities or O&P patient-care practice
acquisition program. See "Business--Competition."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  As of May 31, 1998, the Company had 15,740,631 shares of Common Stock
outstanding, of which 14,641,631 shares are freely tradeable without
restriction under the federal securities laws, except for shares held by
affiliates of the Company. Of the currently outstanding shares, 1,099,000
shares constitute "restricted securities" as that term is defined under Rule
144 under the Securities Act of 1933, with 1,042,295 shares being eligible for
resale at this time, subject to compliance with volume limitations and other
restrictions under Rule 144, and the balance of 56,705 shares to be eligible
for resale under Rule 144 commencing December 31, 1998. In addition, the
Company has an outstanding note which is convertible into Common Stock
beginning on March 31, 1999. If the holder of this note exercises his right to
convert one-fifth of the principal amount of the note annually, an additional
23,143 shares would be eligible for resale on each of March 31, 1999, 2000,
2001, 2002 and 2003. As of May 31, 1998, there were a total of 1,550,071
shares of Common Stock underlying outstanding options (of which options for
371,647 shares are presently exercisable) and 1,190,649 shares underlying
currently exercisable warrants to purchase shares from the Company. The shares
underlying substantially all of the outstanding options will be freely
tradeable upon issuance as a result of a currently effective registration
statement relating to certain of the Company's stock option plans and the
holders of substantially all of the outstanding warrants have rights to
require the Company to register the underlying shares. The Company and its
executive officers and directors and certain stockholders owning an aggregate
of 2,117,104 shares of Common Stock and options and warrants to purchase
1,321,149 shares have agreed that they will not sell any shares of Common
Stock held by them for a period of 90 days from the date of this Prospectus
without the prior written consent of BT Alex. Brown Incorporated. No
prediction can be made as to the effect, if any, that sales of shares of
Common Stock, or the availability of such shares for sale, will have on the
market prices of the Company's Common Stock prevailing from time to time. The
possibility that substantial amounts of shares may be sold in the public
market may adversely affect prevailing market prices for the Common Stock and
could impair the Company's ability to raise capital through the sale of its
equity securities.
 
ABSENCE OF DIVIDENDS
 
  The Company has never declared or paid, nor does it intend to declare or pay
in the foreseeable future, cash dividends on its Common Stock, but intends
instead to retain any future earnings to finance expansion and operations. In
addition, the Company's agreement with its senior bank lender contains a
minimum net worth covenant and prohibits the payment of cash dividends. See
"Dividend Policy" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
UNCERTAINTIES RELATING TO YEAR 2000 CONSEQUENCES
 
  Although the Company believes that its internal management information
systems are Year 2000 compliant, no assurance can be given that its business
will not be adversely affected by possible Year 2000 problems of third
parties. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from this offering, after deducting
estimated underwriting discounts and offering expenses, are estimated to be
approximately $45.1 million ($54.6 million if the Underwriters' over-allotment
option is exercised), based on an assumed public offering price of $20.13 per
share. The Company will not receive any of the proceeds from the sale of
shares of Common Stock by the Selling Stockholders.
 
  The Company intends to use the net proceeds of the offering to repay,
without penalty, existing indebtedness primarily incurred under a credit
agreement (the "Credit Agreement") with a syndicate of banks (collectively,
the "Banks") that provides for: (i) an A-Term Loan Commitment of up to $29.0
million (the "A-Term Loan"); (ii) a B-Term Loan Commitment of up to $28.0
million (the "B-Term Loan"); (iii) an acquisition loan of up to $25.0 million
(the "Acquisition Loan"); and (iv) a revolving loan of up to $8.0 million (the
"Revolving Loan"). The Company's long-term debt at March 31, 1998, including a
current portion of approximately $10.3 million, was approximately $39.6
million, with such indebtedness consisting of: (i) approximately $8.3 million
borrowed under the A-Term Loan, which bears interest at the rate of 7.188% per
annum and matures on December 31, 2001; (ii) approximately $8.6 million
borrowed under the B-Term Loan, which bears interest at the rate of 7.438% per
annum and matures on December 31, 2003; (iii) $5.0 million borrowed under the
Acquisition Loan, which bears interest at the rate of 6.938% per annum and
matures on November 1, 2001; (iv) $4.0 million borrowed under the Revolving
Loan, which bears interest at the rate of 6.938% per annum and matures on
November 1, 2001; and (v) approximately $13.7 million of other indebtedness,
primarily consisting of subordinated seller notes.
 
  Of the approximately $39.6 million principal amount of existing indebtedness
of the Company, the following amounts will be repaid out of the net proceeds
to the Company of this offering: (i) approximately $8.3 million principal
amount of the A-Term Loan; (ii) approximately $8.6 million principal amount of
the B-Term Loan; (iii) $5.0 million principal amount of the Acquisition Loan;
(iv) $4.0 million principal amount of the Revolving Loan; and (v)
approximately $1.7 million of other indebtedness, primarily consisting of
subordinated seller notes.
 
  The remaining net proceeds to the Company from this offering will be used
for general corporate purposes, which may include future acquisitions.
Although the Company regularly reviews strategic opportunities, the Company
currently has no binding agreements with respect to any material acquisitions.

                                DIVIDEND POLICY
 
  The Company has never declared or paid, nor does it intend to declare or pay
in the foreseeable future, cash dividends on the Common Stock, but intends
instead to retain future earnings to finance expansion and operations. In
addition, certain financial covenants in the Company's loan agreement with the
Banks limit the ability of the Company to pay dividends or make other
distributions on the Common Stock.
 
                          PRICE RANGE OF COMMON STOCK
 
  The Common Stock of the Company has been included for quotation on the
American Stock Exchange under the symbol "HGR" since April 1991. The following

(1) The 1994 results include restructuring costs of $460,000 associated with
    the closing of unprofitable patient-care centers and a loss from the
    disposal of assets of $2.2 million resulting from the sale of the
    Company's southern California patient-care centers. The 1996 results
    include acquisition and integration costs of $2.5 million incurred in
    connection with the purchase of JEH effective November 1, 1996.
(2) Loss from discontinued operations consists of the loss from discontinued
    operations and the sale of the discontinued operation of the Company's
    Apothecaries, Inc. subsidiary, the assets of which were sold in 1994.
(3) During the fourth quarter of 1997, the Company adopted the provisions of
    SFAS 128 and, as required, has restated all prior period per common share
    data. Basic per common share amounts are computed using the weighted
    average number of common shares outstanding during the period. Diluted per
    common share amounts are computed using the weighted average number of
    common shares outstanding during the period and dilutive potential common
    shares. Dilutive potential common shares consist of stock options and
    stock warrants and are calculated using the treasury stock method. Both
    basic and diluted per common share amounts have been adjusted for
    preferred stock dividends.
(4) Adjusted to give effect to: (i) acquisitions which occurred during 1997
    and the five months ended May 31, 1998; and (ii) the reduction in interest
    expense resulting from the application of the estimated net proceeds of
    this offering upon the sale by the Company of 2,400,000 shares of Common
    Stock offered hereby at an assumed public offering price of $20.13, as if
    all such transactions had occurred on January 1, 1997. See "Use of

certain assumptions management believes are reasonable. These adjustments are
directly attributable to the transactions and are expected to have a
continuing impact on the financial condition and results of operations of the

 (1) The historical statements of income data for the 1998 Acquired Companies
     for the quarter ended March 31, 1998 represent the results of operations
     of such companies from January 1, 1998 to the earlier of their respective
     dates of acquisition or March 31, 1998. Each of the acquisitions has been
     accounted for as a purchase. Accordingly, the results of operations for
     each of the 1998 Acquired Companies are included in the historical
     results of operations of the Company from the date of its acquisition.
 
 (2) The adjustments to reduce sales ($148,174) and cost of sales ($143,456)
     reflect the elimination of profit on intercompany sales during the period
     presented.
 
 (3) The adjustments to reduce selling, general and administrative ($21,957),
     interest income ($14,581) and other income ($7,618) reflect the
     elimination of historical income and expenses generated from 1998
     Acquired Companies assets not acquired.
 
 (4) Reflects increases in historical amounts of the 1998 Acquired Companies
     for both amortization expense resulting from the revaluation in purchase
     accounting of intangible assets and additional amortization over a 40-
     year period, as if such 1998 Acquired Companies were acquired as of the
     beginning of the period presented.
 
 (5) Includes a net reduction to historical amounts of $321,163 for employee
     and practitioner salaries of the 1998 Acquired Companies to reflect the
     difference between such historical amounts and amounts either specified
     in employment contracts for comparable employment positions with the
     Company or to reflect positions eliminated which will not subsequently be
     filled by the Company. Such employment agreements or eliminations were
     signed or executed concurrent with the signing of the respective purchase
     agreements.
 
 (6) The additional interest expense of $170,666 reflects what would have been
     incurred if the consideration (in the form of cash and promissory notes)
     for the 1998 Acquired Companies had been paid at January 1, 1998. The
     interest rate used to calculate pro forma interest (7.0%) on the assumed
     additional debt required to fund the cash payments reflects the Company's
     approximate borrowing rate.
 
 (7) Reflects income taxes as if the Company and the acquired companies were
     each a C Corporation for the period presented.
 
 (8) Reflects the application of the estimated net proceeds of this offering
     as if this transaction occurred as of March 31, 1998. Pro forma net
     interest expense, net income and net income per common share amounts do
     not include approximately $205,000 of interest income that would have
     been earned assuming the $16.6 million increase in cash had been invested
     in cash equivalents earning 5.0%. If interest income had been reflected,
     basic and diluted per common share amounts, on a pro forma as adjusted
     basis, would have been $0.12 and $0.11, respectively. The following
     reflects the debt to be repaid by the Company from the net proceeds of
     the offering and the debt to be outstanding as of March 31, 1998 on a pro
     forma as adjusted basis:

 (9) Represents the adjustments to income taxes which would have been provided
     on a pro forma as adjusted income before income taxes basis using an
     effective tax rate of 41%.
 
(10) Basic per common share amounts are computed using the weighted average
     number of common shares outstanding during the year. Diluted per common
     share amounts are computed using the weighted average number of common
     shares outstanding during the year and dilutive potential common shares.
     Dilutive potential common shares consist of stock options and stock
     warrants and are calculated using the treasury stock method. The shares
     used in computations of net income per common share on a pro forma as
     adjusted basis also include Common Stock being sold pursuant to this
     offering. Both basic and diluted per common share amounts have been
     adjusted for preferred dividends.
 
(11) The unaudited pro forma amounts exclude the impact of potential future
     contingent consideration to be paid to former shareholders of acquired
     companies based on prescribed formulas. Contingent consideration is to be
     accounted for as additional purchase price consideration if and when it
     becomes probable.

 (1) The historical statements of income for the 1997 Acquired Companies and
     the 1998 Acquired Companies for the year ended December 31, 1997
     represent the results of operations for such companies from January 1,
     1997 to the earlier of their respective dates of acquisition or December
     31, 1997. Each of the acquisitions has been accounted for as a purchase.
     Accordingly, the results of operations for each of the 1997 Acquired
     Companies and the 1998 Acquired Companies are included in the historical
     results of operations of the Company from the date of its acquisition.
 
 (2) The adjustments to reduce sales ($978,387) and cost of sales ($947,235)
     reflect the elimination of profit on intercompany sales during the period
     presented.
 
 (3) The adjustments to reduce selling, general and administrative ($204,764),
     interest income ($48,654) and other income ($28,902) reflect the
     elimination of historical income and expenses generated from the 1997
     Acquired Companies and 1998 Acquired Companies assets not acquired.
 
 (4) Reflects increases in historical amounts of the 1997 Acquired Companies
     and the 1998 Acquired Companies for both amortization expense resulting
     from the revaluation in purchase accounting of intangible assets and
     additional amortization over a 40-year period, as if such 1997 Acquired
     Companies and 1998 Acquired Companies were acquired as of the beginning
     of the period presented.
 
 (5) Includes a net reduction to historical amounts of $1,654,279 for employee
     and practitioner salaries of the 1997 Acquired Companies and the 1998
     Acquired Companies to reflect the difference between such historical
     amounts and amounts either specified in employment contracts for
     comparable employment positions with the Company. Such employment
     agreements or eliminations were signed or executed concurrent with the
     signing of the respective purchase agreements.
 
 (6) The additional interest expense of $2,144,219 reflects what would have
     been incurred if the consideration (in the form of cash and promissory
     notes) for the 1997 Acquired Companies and the 1998 Acquired Companies
     had been paid at January 1, 1997. The interest rate used to calculate pro
     forma interest (approximately 7.7%) on the assumed additional debt
     required to fund the cash payments reflects the Company's approximate
     borrowing rate.
 
 (7) Reflects income taxes as if the Company and the acquired companies were
     each a C Corporation for the period presented.
 
 (8) Represents the assumed application of estimated net proceeds of this
     offering as of the beginning of the period presented. Pro forma net
     interest expense, net income and net income per common share amounts do
     not include approximately $730,000 of interest income that would have
     been earned assuming the $14.6 million increase in cash had been invested
     in cash equivalents earning 5.0%. If interest income had been reflected,
     basic and diluted per common share amounts, on a pro forma as adjusted
     basis, would have been $0.73 and $0.67, respectively. The following
     reflects the debt to be repaid by the Company from the net proceeds of
     this offering and the debt to be outstanding as of December 31, 1997 on a

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
  The following discussion is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements and Notes thereto
appearing elsewhere in this Prospectus.
 
OVERVIEW
 
  The significant growth in the Company's O&P professional practice management
net sales has resulted from an aggressive program of acquiring and developing
O&P patient-care centers. Similarly, growth in the Company's O&P distribution
and manufacturing net sales is attributable primarily to acquisitions. Since
1986, when the Company acquired its first O&P practice, the Company has
acquired over 60 businesses and presently owns and operates 240 patient-care
centers, six distribution facilities, three of which contain central
fabrication operations, and two manufacturing facilities. Since 1995, the
Company has significantly expanded OPNET, its national O&P preferred provider
network, in order to facilitate contracting with managed care organizations on
a national level.
 
COMPANY EXPANSION
 
  During late 1994 and 1995, the Company closed or sold nine unprofitable
patient-care centers and temporarily discontinued its acquisition program.
Following a change in executive management in mid-1995 and a refinancing in
1996, the Company's acquisition program was resumed. The significant increase
in the number of patient-care centers and certified practitioners in 1996 is
attributable primarily to the Company's acquisition of JEH. The following
table sets forth the number of patient-care centers, certified practitioners
and states (including the District of Columbia) in which the Company operated
at the end of each of the past five years and at March 31, 1997 and 1998:

</TABLE>
 
NON-RECURRING CHARGES
 
  The Company's results of operations prior to 1997 were adversely affected by
certain non-recurring charges, the most significant of which were associated
with: (i) the sale or closure of unprofitable patient-care centers and related
restructuring charges recorded in 1994; and (ii) non-recurring acquisition and
integration costs incurred in 1996 in connection with the acquisition of JEH.

RECENT ACQUISITIONS
 
  During 1997, the Company acquired nine O&P companies for an aggregate
consideration, excluding potential earn-out provisions, of $21.4 million.
These O&P companies, which operate 29 patient-care centers and
 
                                      24
<PAGE>
 
employ 175 persons, had combined net sales of $19.2 million in the year ended
December 31, 1997. During the five months ended May 31, 1998, the Company
acquired five O&P companies for an aggregate consideration, excluding
potential earn-out provisions, of approximately $14.9 million. These O&P
companies, which operate 25 patient-care centers and employ 110 persons, had
combined net sales of approximately $14.6 million in the year ended December
31, 1997.
 
SAME-CENTER SALES GROWTH
 
  In addition to acquisitions of new patient-care centers, the growth in the
Company's net sales from O&P patient-care services is attributable to a lesser
degree to increases in net sales from existing patient-care centers. In 1994,
the Company's decline in same-center net sales growth was primarily a result
of poor operating performance at several centers that the Company subsequently
sold or closed, the loss of several practitioners and severe weather
conditions in the first quarter. The following table sets forth, for the
periods indicated, the percent increase (decrease) in net sales contributed by
those patient-care centers that were open during the entire period as well as
the prior year's entire comparable period:

CENTER-LEVEL RESULTS BY YEAR
 
  The Company generally experiences rapid growth in net sales in the first two
calendar years following an acquisition or a new patient-care center opening,
with rates of growth moderating in the following years. The following table
represents the aggregate net sales growth of the Company's patient-care
centers that have been acquired or opened since 1990:
 
<TABLE>
<CAPTION>

Aggregate net sales growth................   12.7%    7.5%   1.1%   0.1%   5.6%
</TABLE>
- --------
(1) Year 1 represents the second full year of operation by the Company
    following the center's acquisition or opening divided by the first full
    year of operation by the Company.
 
  The Company also tracks profitability as measured by center-level EBITDA
contribution before corporate overhead allocation, as shown in the following
table:
 
<TABLE>
<CAPTION>
                                           YEAR 1(2) YEAR 2 YEAR 3 YEAR 4 YEAR 5

EBITDA contribution margin................   23.5%   19.7%  23.9%  21.5%  24.9%
</TABLE>
- --------
(2) Year 1 represents the first full year of operations by the Company
    following the center's acquisition or opening. EBITDA contribution margin
    is defined as net income (loss) before interest expense, taxes,
    depreciation and amortization, discontinued operations, non-recurring
    charges, extraordinary item and accounting change as a percent of center-
    level net sales.
 
  Aggregate net sales growth for year 3 and 4, and EBITDA contribution margin
for year 4, were negatively affected due to the underperformance in the years
ended December 31, 1994 and 1995 of centers acquired in 1990 and 1991,
respectively. This underperformance is primarily attributable to the loss of
certain O&P practitioners and the underperformance by certain of the Company's
patient-care centers. As previously discussed, the Company closed or sold nine
unprofitable patient-care centers and replaced previously vacant practitioner
positions beginning in late 1994 through 1995.

  Although the Company's net sales continue to be most significantly derived
from O&P practice management activities, including patient-care services, the
percent of the Company's total net sales attributable to O&P distribution
activities has increased. The following table sets forth the percent
contributed to net sales in each of the periods indicated by the principal
sources of the Company's net sales. The increase in the
 
                                      25
<PAGE>
 
percent of net sales contributed by distribution activities in 1997 is
attributable to the Company's acquisition of JEH in late 1996 and increased
sales to O&P practitioners in the Company's OPNET network. Manufacturing as a
percent of net sales declined to 5.3% in 1997 versus 12.0% in 1996. However,
there was a slight increase in the actual dollar amount of net sales
attributable to manufacturing.

PAYOR MIX
 
  The Company receives payments for O&P services rendered to patients from
private insurers, HMOs, PPOs, the patients directly and governmental payors,
including Medicare, Medicaid and the VA. The sources and amounts of the
Company's net sales derived from its patient-care centers are determined by a
number of factors, including the number and nature of O&P services rendered
and the rates of reimbursement among payor categories. Generally, private
insurance and other third-party reimbursement levels are greater than managed
care (HMO/PPO), Medicare, Medicaid and VA reimbursement levels. Changes in the
Company's payor mix can affect its profitability. The following table sets
forth the percent contributed to net sales in each of the following periods by
the principal categories of payors:

(1) Payor mix data for the years ended December 31, 1996 and 1997 and for the
    quarters ended March 31, 1997 and 1998 is based on a sampling of
    approximately 75% of the patient-care centers in each of such years.
 
EBITDA AND OPERATING MARGIN TRENDS
 
  The Company's EBITDA and operating margins have fluctuated over the past
five years. In 1994, margins decreased due to the loss of several
practitioners, poor operating performance at several centers and severe
weather in the first quarter of the year. In 1995, margins increased to 1993
levels due to the sale and/or closing of the unprofitable practices. In 1996,
margins declined slightly compared to 1995 as a result of the JEH acquisition.
JEH derived a larger percent of its net sales from distribution as compared to
the Company, and its distribution operations had lower gross profit margins
than its patient-care services. Also causing the decline in margins in 1996
was a decision by the management of the Company not to eliminate any
duplicative expenses during the two months ended December 31, 1996 following
the JEH acquisition. Exclusive of the JEH acquisition, EBITDA margins
increased in 1996 as compared to 1995. In 1997, margins were higher than 1996
primarily from the integration of JEH and the elimination of duplicative
expenses. In the first quarter of the year, margins are typically lower than
full-year margins due to seasonal trends in the O&P industry. The EBITDA
margin in the first quarter of 1998 decreased compared to the first quarter of
1997 as a result of the increase in the provision for bad debt expense as a
percent of net sales. The following table tracks the trends in the Company's
EBITDA and operating margins:

SEASONALITY
 
  The Company's results of operations are affected by seasonal considerations.
The adverse weather conditions often experienced in certain geographic areas
of the United States during the first quarter of each year, together with a
greater degree of patients' sole responsibility for their insurance deductible
payment obligations during the beginning of each calendar year, have
contributed to lower Company net sales during that quarter.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31,
1997
 
  Net Sales. Net sales for the three months ended March 31, 1998 were
approximately $40.8 million, an increase of approximately $9.8 million, or
31.7%, over net sales of approximately $30.9 million for the three months
ended March 31, 1997. Contributing to the increase were: (i) a 13.8% increase
in sales by those Hanger patient-care centers operating in both periods
("same-center sales"); and (ii) sales by patient-care centers acquired by
Hanger subsequent to March 31, 1997.
 
  Gross Profit. Gross profit during the three months ended March 31, 1998 was
approximately $19.4 million, an increase of approximately $4.7 million, or
32.1%, over gross profit of approximately $14.7 million for the three months
ended March 31, 1997. Gross profit as a percent of net sales for the three
months ended March 31, 1998 and 1997 remained approximately the same at 47.7%
and 47.6%, respectively.
 
  Selling, General and Administrative. Selling, general and administrative
expenses in the three months ended March 31, 1998 were approximately $14.7
million, an increase of approximately $3.8 million, or 34.8%, compared to
$10.9 million for the three months ended March 31, 1997. The increase in
selling, general and administrative expenses was primarily a result of the
Company's acquisition program. Selling, general and administrative expenses as
a percent of net sales for the three months ended March 31, 1998 and 1997
increased to 36.1% from 35.3%, respectively.
 
 
                                      27

  Income from Operations. Principally as a result of the above, income from
operations in the three months ended March 31, 1998 was approximately $3.5
million, an increase of approximately $822,000, or 31.2%, over income from
operations of $2.6 million for the three months ended March 31, 1997. Income
from operations as a percent of net sales for the three months ended March 31,
1998 and 1997 remained the same at 8.5%.
 
  Interest Expense. Interest expense in the first three months of 1998 was
approximately $615,000, a decrease of approximately $912,000, or 59.7%, from
the approximately $1.5 million of interest expense incurred in the first three
months of 1997. Interest expense as a percent of net sales for the three
months ended March 31, 1998 and 1997 decreased to 1.5% from 4.9%,
respectively. The decrease was primarily attributable to the repayment of
$58.0 million of indebtedness in July and August 1997 using the net proceeds
of an underwritten public offering in which the Company sold 5,750,000 shares
of Common Stock at $11.00 per share.
 
  Provision for Income Taxes. The Company's effective tax rate was 41% in the
first three months of 1998 versus 42% for the first three months of 1997. The
provision for income taxes in the first three months of 1998 was approximately
$1.2 million compared to approximately $447,000 in the first three months of
1997.
 
  Net Income. As a result of the above, the Company recorded net income of
approximately $1.7 million, or $0.10 per common dilutive share on
approximately 17,082,000 shares outstanding for the three months ended March
31, 1998, compared to net income of approximately $618,000, or $0.06 per
common dilutive share on approximately 9,941,000 shares outstanding in the
three months ended March 31, 1997.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
  Net Sales. Net sales for the year ended December 31, 1997 were approximately
$145.6 million, an increase of approximately $78.8 million, or 117.9%, over
net sales of approximately $66.8 million for the year ended December 31, 1996.
The increase was primarily a result of: (i) the acquisition of J.E. Hanger,
Inc. of Georgia ("JEH") on November 1, 1996, as well as other acquisitions
during 1997; and (ii) an 11.7% increase in net sales attributable to patient-
care centers and facilities operating during both periods.
 
  Gross Profit. Gross profit for the year ended December 31, 1997 was
approximately $72.1 million, an increase of approximately $37.5 million, or
108.4%, over gross profit of approximately $34.6 million for the year ended
December 31, 1996. The cost of products and services sold for the year ended
December 31, 1997 was approximately $73.5 million compared to $32.2 million
for the year ended December 31, 1996. Gross profit as a percent of net sales
for patient-care services for the years ended December 31, 1997 and 1996
remained the same at 55.1%. Gross profit as a percent of net sales for
manufacturing and distribution was 44.9% and 16.0% for those years,
respectively. The total Company gross profit as a percent of net sales
declined from 51.8% in 1996 to 49.5% in 1997. The 2.3% decrease in the
Company's gross profit as a percent of net sales is primarily attributable to
the acquisition of JEH, which operated a large distribution division that had
lower gross profit margins than those of patient-care services.
 
  Selling, General and Administrative. Selling, general and administrative
expenses for the year ended December 31, 1997 were approximately $49.1
million, an increase of approximately $24.5 million, or 99.9%, compared to
approximately $24.5 million for the year ended December 31, 1996. The increase
in selling, general and administrative expenses was primarily a result of the
acquisition of JEH and other acquisitions. Selling, general and administrative
expenses as a percent of net sales decreased to 33.7% in 1997 from 36.7% in
1996. The selling, general and administrative expenses as a percent of net
sales decreased primarily as a result of cost- cutting measures completed
during the fourth quarter of 1996 and the first six months of 1997.
 
  Income from Operations. Principally as a result of the above, income from
operations for the year ended December 31, 1997 was approximately $18.3
million, an increase of $13.6 million, or 290.0%, compared to approximately
$4.7 million for the year ended December 31, 1996. Income from operations as a
percent of net sales increased to 12.6% in 1997 from 7.0% in 1996.
 
  Interest Expense. Interest expense for the year ended December 31, 1997 was
approximately $4.9 million, an increase of approximately $2.4 million, or
93.7%, compared to approximately $2.5 million of interest expense incurred
during the year ended December 31, 1996. Interest expense as a percent of net
sales decreased to 3.4%
 
                                      28
<PAGE>
 
in 1997 from 3.8% for 1996. The increase in interest expense was primarily
attributable to the increase in bank debt resulting from the acquisition of
JEH in November 1996, which was offset in part by the repayment of bank debt
out of the proceeds of the public equity offering in the third quarter of
1997.
 
  Provision for Income Taxes. The Company's effective tax rate was 42% in 1997
versus 45% in 1996. The decrease in 1997 is a result of the disproportionate
impact of the amortization of the excess costs over net assets acquired in
relation to taxable income in 1996.
 
  Extraordinary Item. A pre-tax extraordinary item of $4.6 million ($2.7
million, net of tax benefit) in 1997, represents entirely a write-off of debt
issue costs and debt discount as a result of extinguishing approximately $58.3
million of bank debt from the net proceeds of the third-quarter public equity
offering.
 
  Net Income. As a result of the above, the Company recorded net income from
operations before extraordinary item of $7.6 million for the year ended
December 31, 1997, compared to $1.1 million for the prior year. A pre-tax
extraordinary item of $4.6 million ($2.7 million, net of tax benefit) on early
extinguishment of debt was recognized in 1997 compared to $139,000 ($83,000,
net of tax benefit) in 1996. Both extraordinary items were in connection with
refinancings of bank indebtedness.
 
  As a result of the above, the Company reported net income of $4.9 million,
or $0.37 per common dilutive share, for the year ended December 31, 1997, as
compared to net income of $998,000, or $0.11 per common dilutive share, for
the year ended December 31, 1996.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Net Sales. Net sales for the year ended December 31, 1996 were approximately
$66.8 million, an increase of approximately $14.3 million, or 27.3%, over net
sales of approximately $52.5 million for the year ended December 31, 1995. The
increase was primarily a result of: (i) an increase of $12.1 million
attributable to the acquisition of JEH; and (ii) an increase of $2.2 million,
or 5.6%, in net sales attributable to patient-care centers and facilities that
were in operation during both periods. Of the $2.2 million increase in net
sales, $1.8 million was attributable to patient-care centers and $293,000 was
attributable to manufacturing and distribution activities.
 
  Gross Profit. Gross profit in 1996 increased approximately $6.7 million, or
23.9%, over the prior year. Gross profit as a percent of net sales decreased
from 53.2% in 1995 to 51.8% in 1996. The 1.4% decrease in gross profit as a
percent of net sales is primarily attributable to the acquisition of JEH,
which operated a large distribution division that had lower gross profit
margins than patient-care services. The cost of products and services sold for
the year ended December 31, 1996 was $32.2 million compared to $24.6 million
in 1995.
 
  Selling, General and Administrative. Selling, general and administrative
expenses in 1996 increased approximately $5.2 million, or 26.8%, compared to
1995. The increase in selling, general and administrative expenses was
primarily a result of the acquisition of JEH. Selling, general and
administrative expenses as a percent of net sales stayed approximately the
same at 37%.
 
  Acquisition and Integration Costs. Non-recurring acquisition and integration
costs totaling $2.5 million in 1996 consisted of: (i) $1.3 million of bonuses
and legal and consulting expenses incurred to acquire JEH; and (ii) $1.2
million of costs to integrate the operations of JEH with the Company,
including costs of severance and the conversion of its health insurance plan
and computer systems.
 
  Income from Operations. Principally as a result of the above, income from
operations in 1996 was approximately $4.7 million, a decrease of $1.1 million
from the prior year. Income from operations as a percent of net sales in 1996
decreased to 7.0% from 11.1% in 1995.
 
  Interest Expense. Interest expense for the year ended December 31, 1996 was
approximately $2.5 million, an increase of $490,000, or 23.9%, over the $2.1
million of interest expense incurred during the year ended December 31, 1995.
The increase in interest expense was primarily attributable to the increase in
bank debt resulting from the acquisition of JEH. Interest expense as a percent
of net sales was 3.8% for the year ended December 31, 1996, compared to 3.9%
for 1995.
 
                                      29
<PAGE>
 
  Provision for Income Taxes. The Company's effective tax rate was 45% in 1996
versus 42% in 1995. The increase in 1996 reflects both the recognition of a
state deferred tax benefit in 1995, which did not occur in 1996, and the
disproportionate impact of permanent differences in relation to taxable
income.
 
  Net Income. As a result of the above, the Company reported income from
operations before extraordinary item and accounting change of $1.1 million for
the year ended December 31, 1996, compared to $2.1 million for the prior year.
A pre-tax extraordinary item of $139,000 ($83,000, net of tax benefit) on
early extinguishment of debt was recognized in 1996 in connection with the
Company's refinancing of bank indebtedness.
 
  As a result of the above, the Company reported net income of $998,000, or
$0.11 per common dilutive share, for the year ended December 31, 1996, as
compared to net income of $2.1 million, or $0.25 per common dilutive share,
for the year ended December 31, 1995.
 
PRO FORMA RESULTS FOR THE YEAR ENDED DECEMBER 31, 1997 AND THE THREE MONTHS
ENDED MARCH 31, 1998
 
  The Unaudited Pro Forma Condensed Consolidated Statements of Income for the
year ended December 31, 1997 and the three months ended March 31, 1998 are
based on the historical consolidated statements of income of the Company,
adjusted to give effect to the acquisitions of both the 1997 Acquired
Companies and the 1998 Acquired Companies. The Unaudited Pro Forma Condensed
Consolidated Statements of Income for the year ended December 31, 1997 and the
three months ended March 31, 1998 have been prepared assuming such
acquisitions occurred as of January 1, 1997. The Unaudited Pro Forma Condensed
Consolidated Statements of Income also give effect to the reduction in
interest expense resulting from the expected application of the estimated net
proceeds of this offering to retire certain outstanding debt of the Company as
if such retirement occurred on January 1, 1997. See "Use of Proceeds."
 
  The Unaudited Pro Forma Condensed Consolidated Statements of Income do not
purport to represent what the Company's results of operations would have been
had the acquisitions of both the 1997 Acquired Companies and 1998 Acquired
Companies occurred as of the beginning of the period presented or to project
the Company's results of operations for any future date or period, nor do they
give effect to any matters other than those described in the notes thereto.
For a description of adjustments made to the historical financial statements,
see "Selected Unaudited Pro Forma Condensed Consolidated Financial
Information" and the notes thereto.
 
  The effect of the acquisitions of both the 1997 Acquired Companies and the
1998 Acquired Companies was to increase net sales by approximately $25.0
million in the year ended December 31, 1997 and $2.3 million in the three
months ended March 31, 1998 above the Company's historical results for such
periods. The 1997 Acquired Companies and 1998 Acquired Companies had a gross
profit margin of 50.6% of net sales in the year ended December 31, 1997 and
48.4% of net sales in the three months ended March 31, 1998. Gross profit
margins of the Company on a pro forma as adjusted basis were 49.9% of net
sales for the year ended December 31, 1997 and 47.9% of net sales for the
three months ended March 31, 1998. The Acquired Companies' selling, general
and administrative expenses as a percent of net sales were 43.5% in the year
ended December 31, 1997 and 54.2% of net sales for the three months ended
March 31, 1998. Selling, general and administrative expenses of the Company on
a pro forma as adjusted basis were 34.3% of net sales for the year ended
December 31, 1997 and 36.5% of net sales for the three months ended March 31,
1998 as a result of adjustments to eliminate Acquired Company compensation,
and other expenses. As a result of the above, the Company's income from
operations on a pro forma as adjusted basis was 13.0% of net sales for the
year ended December 31, 1997 and 8.3% for the three months ended March 31,
1998. Interest expense on a pro forma as adjusted basis decreased by
approximately $238,000 for the year ended December 31, 1997 and $348,000 for
the three months ended March 31, 1998 after the application of the estimated
net proceeds of this offering to retire certain indebtedness. See "Use of
Proceeds" and "Selected Unaudited Pro Forma Condensed Consolidated Financial
Information."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's consolidated working capital at March 31, 1998 was
approximately $35.9 million. Cash and cash equivalents available at that date
were approximately $5.7 million. The Company's cash resources were
satisfactory to meet its obligations for the three months ended March 31,
1998.
 
                                      30

  The Company has a credit agreement (the "Credit Agreement") with a syndicate
of banks, (collectively, the "Banks") that provides for: (i) the A-Term Loan
of up to $29.0 million; (ii) the B-Term Loan of up to $28.0 million; (iii) the
Acquisition Loan of up to $25.0 million; and (iv) the Revolving Loan of up to
$8.0 million.
 
  The Company's total long-term debt at March 31, 1998, including a current
portion of approximately $10.3 million, was approximately $39.6 million. Such
indebtedness included: (i) $16.9 million borrowed under the A-Term Loan and B-
Term Loan; (ii) $5.0 million borrowed under the Acquisition Loan; (iii) $4.0
million borrowed under the Revolving Loan; and (iv) approximately $13.7
million of other indebtedness, primarily consisting of subordinated seller
notes.
 
  The Credit Agreement with the Banks is collateralized by substantially all
the assets of the Company, restricts the payment of dividends, and contains
certain affirmative and negative covenants customary in an agreement of this
nature.
 
  The A-Term Loan, the Acquisition Loan and the Revolving Loan bear base
interest at the Company's option of either LIBOR plus 2.50% or the Bank's
prime rate plus 1.50%. The base interest rate is then reduced by 0.25% to
1.25% depending upon the ratio of the Company's total indebtedness to annual
earnings before interest, taxes, depreciation and amortization. The
outstanding amount of the A-Term Loan at March 31, 1998 was $8.3 million,
which is being amortized in quarterly amounts and will mature on December 31,
2001.
 
  The B-Term Loan bears base interest at the Company's option of either LIBOR
plus 2.75% or the Bank's prime rate plus 1.75%. The base interest rate is then
reduced by 0.25% to 1.25% depending upon the ratio of the Company's total
indebtedness to annual earnings before interest, taxes, depreciation and
amortization. The outstanding amount of the B-Term Loan at March 31, 1998 was
$8.6 million, which is being amortized in quarterly amounts and will mature on
December 31, 2003.
 
  All or any portion of outstanding loans under the Credit Agreement may be
repaid at any time and commitments may be terminated in whole or in part at
the option of the Company without premium or penalty, except that LIBOR-based
loans may only be repaid at the end of the applicable interest period.
Mandatory prepayments will be required in the event of certain sales of
assets, debt or equity financings and under certain other circumstances.
Reference is made to "Use of Proceeds" above for information regarding the
Company's planned prepayment of outstanding loans under the Credit Agreement.
 
  During the first three months of 1998, the Company acquired three O&P
companies. The aggregate purchase price was $13.2 million, comprised of $10.4
million in cash and $2.8 million in promissory notes.
 
  The Company plans to finance future acquisitions through internally
generated funds or borrowings under the Acquisition Loan, the issuance of
notes or shares of Common Stock of the Company, or through a combination
thereof.
 
  The Company is actively engaged in ongoing discussions with prospective
acquisition candidates. The Company plans to continue to expand its operations
aggressively through acquisitions.
 
OTHER
 
  Inflation has not had a significant effect on the Company's operations, as
increased costs to the Company generally have been offset by increased prices
of products and services sold.
 
  The Company will adopt the provisions of SFAS 131, "Disclosures about
Segments of an Enterprise and Related Information" effective with the
financial statements for the year ended December 31, 1998. SFAS 131
establishes standards for the way that public business enterprises report
information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports issued to stockholders. It also
establishes standards for related disclosures about products and services,
geographic areas, and major customers. Financial statement disclosures for
prior periods are required to be restated. The Company is in the process of
evaluating the disclosure requirements. The adoption of SFAS 131 affects
disclosure only and will not affect reported earnings, cash flows or financial
condition.

  The Company primarily provides services and customized devices throughout
the United States and is reimbursed, in large part, by the patients' third-
party insurers or governmentally funded health insurance programs. The ability
of the Company's debtors to meet their obligations is principally dependent
upon the financial stability of the insurers of the Company's patients and
future legislation and regulatory actions.
 
  The Company's management believes that its major financial and manufacturing
applications are Year 2000 compliant. The Company expects no material impact
on its internal information systems from the Year 2000 issue. The Company has
recently initiated communications with its significant suppliers to determine
the extent that the Company may be impacted by the third parties' failure to
address the issue. The Company will continue to monitor and evaluate the
impact of the Year 2000 issue on its operations.

OVERVIEW
 
  Hanger Orthopedic Group, Inc. is a professional practice management company
focused on the orthotic and prosthetic segment of the orthopedic
rehabilitation industry. The Company acquires and operates the practices of
orthotists and prosthetists, medical professionals that design, fabricate, fit
and supervise the use of external musculoskeletal support devices and
artificial limbs. The Company has acquired over 60 O&P businesses since 1986
and currently employs 280 certified O&P practitioners and owns and operates
240 O&P patient-care centers in 30 states and the District of Columbia. The
Company has also developed OPNET, a national preferred provider network of O&P
service professionals. OPNET has contractual relationships with 358 O&P
patient-care centers (240 of which are owned and operated by the Company),
serving 291 managed care plans. In addition to its practice management and
patient-care services, the Company manufactures custom-made and prefabricated
O&P devices and is the largest distributor of O&P components and finished O&P
patient-care products in the United States. The combination of practice
management and patient-care services, OPNET, distribution and manufacturing
operations positions the Company as a fully-integrated provider of O&P
services.
 
INDUSTRY BACKGROUND
 
  Orthotics is the design, fabrication, fitting and supervised use of custom-
made braces and other devices that provide external support to treat
musculoskeletal disorders. Musculoskeletal disorders are ailments of the back,
extremities or joints caused by traumatic injuries, chronic conditions,
diseases, congenital disorders or injuries resulting from sports or other
activities. Prosthetics is the design, fabrication and fitting of custom-made
artificial limbs for patients who have lost limbs as a result of traumatic
injuries, vascular diseases, diabetes, cancer or congenital disorders.
 
  Care of O&P patients is part of a continuum of rehabilitation services from
diagnosis to treatment and prevention of future injury. This continuum
involves the integration of several medical disciplines that begins with the
attending physician's diagnosis. Once a course of treatment is determined, the
physician, generally an orthopedic surgeon, vascular surgeon or psychiatrist,
refers a patient to an O&P patient-care service provider for treatment. An O&P
practitioner then consults with both the referring physician and the patient
to formulate the prescription for, and design of, an orthotic or prosthetic
device to meet the patient's needs.
 
  The Company estimates that the O&P patient-care services industry in the
United States represented approximately $2.3 billion in sales in 1997. Key
trends expected to increase the demand for O&P services include:
 
  Growing Elderly Population. The growth rate of the over-65 age group is
nearly triple that of the under-65 age group. With broader medical insurance
coverage, increasing disposable income, longer life expectancy, greater
mobility and improved technologies and devices, the elderly are expected to
seek orthopedic rehabilitation services more often.
 
  Cost-Effective Reduction in Hospitalization. As public and private payors
encourage reduced hospital admissions and length of stay, outpatient
rehabilitation is in greater demand. O&P services and devices have enabled
patients to become ambulatory more quickly after receiving medical treatment
in the hospital. The Company believes that significant cost savings can be
achieved through the early use of O&P services. The provision of O&P services
in many cases reduces the need for more expensive treatments, thus
representing a cost savings to the third-party payor.
 
  Growing Physical Health Consciousness. There is a growing emphasis on
physical fitness, leisure sports and conditioning, such as running and
aerobics, which has led to increased injuries requiring orthopedic
rehabilitative services and products. In addition, as the current middle-age
population ages, it brings its more active life-style and accompanying
emphasis on physical fitness to the over-65 age group. These trends are
evidenced by the increasing demand for new devices which provide support for
injuries, prevent further or new injuries or enhance physical performance.
 
  Advancing Technologies. The range and effectiveness of treatment options
have increased in connection with the technological sophistication of O&P
devices. Advances in design technologies and lighter, stronger and
 
                                      33
<PAGE>
 
more cosmetically acceptable materials have enabled the industry to produce
new O&P products, which provide greater comfort, protection and patient
acceptability. Therefore, treatment can be more effective and of shorter
duration, contributing to greater mobility and a more active lifestyle for the
patient. Orthotic devices are more prevalent and visible in many sports,
including skiing, running and golf.
 
  Need for Replacement and Continuing Care. Because the useful life of most
custom-fitted and fabricated O&P devices is approximately three to five years,
such devices need retrofitting and replacement. There is also an attendant
need for continuing patient-care services, which contributes to the increasing
demand for orthopedic rehabilitation.
 
INDUSTRY CONSOLIDATION
 
  The O&P services market is highly fragmented and relatively underpenetrated
by professional practice management companies. Hanger is one of the two
largest companies in the O&P industry which, combined, accounted for less that
15% of the total estimated O&P industry revenue in 1997. There are an
estimated 3,300 certified prosthetists and/or orthotists and approximately
2,850 O&P patient-care centers in the United States, with such facilities
generally being operated as small group practices. There are also several
regional and multi-regional competitors that operate numerous patient-care
centers. The Company believes that the O&P industry will continue to
consolidate as a result of a variety of factors, including:
 
  Increased Managed Care Penetration. The expanding geographic reach of the
large managed care organizations makes it increasingly important for them to
contract for their patient-care needs with counterparts who have large,
national operations. Managed care companies therefore prefer to contract with
a single professional practice management company to provide all of their O&P
patient-care services. As a result, small independent O&P practices feel
pressure to consolidate in order to access managed care referrals.
 
  Economies of Scale.  A significant portion of the cost of O&P services is
attributable to the cost of materials used in orthoses and prostheses.
Achieving purchase discounts through group purchasing can increase
profitability at each patient-care center. In addition, economies of scale
provide O&P practices with access to additional capital and personnel which
can be used in growing their businesses.
 
  Financial Liquidity for O&P Practices. The security of a large O&P network
is extremely appealing to small providers who desire to reduce the financial
and personal liabilities of their practices. Through consolidation, individual
providers are able to realize financial liquidity by turning their practices'
cash flows into cash assets. This consolidation allows smaller providers to
continue their O&P practices as employees of a national O&P professional
practice management provider.
 
COMPANY STRATEGY
 
  The Company's objective is to build a major national orthopedic
rehabilitation company focused on the acquisition and operation of O&P
practices and the manufacturing and distribution of O&P products. The
Company's strategy for achieving this objective is to:
 
  . Acquire and integrate O&P practices in targeted geographic areas across
    the United States;
  . Develop new O&P patient-care centers in existing markets;
  . Expand and improve O&P practice management operations at existing and
    acquired patient-care centers;
  . Increase OPNET's number of O&P patient-care service members and
    contractual relationships with managed care organizations; and
  . Leverage and expand the Company's O&P manufacturing and distribution
    operations.
 
  Acquire and Integrate O&P Practices in Targeted Geographic Areas across the
United States. The Company's expansion is focused on developing a national
network providing O&P patient-care coverage. Therefore, when identifying
patient-care centers for acquisition, the Company seeks to fill gaps in its
existing geographic coverage. By focusing on national development, the Company
is well-positioned to negotiate for national contracts as payors consolidate
and look to large providers for services.
 
                                      34
<PAGE>
 
  Develop New O&P Patient-Care Centers in Existing Markets. In addition to
acquiring patient-care centers, the Company intends to open new O&P patient-
care centers in existing markets. The Company plans to pursue this strategy by
opening satellite centers in areas where a need for O&P services has been
identified. In opening satellite patient-care centers, the Company's practice
is to staff on a part-time basis with professionals from a nearby existing
center so as to test the viability of a full-time practice.
 
  Expand and Improve O&P Practice Management Operations at Existing and
Acquired Patient-Care Centers. As the number of Hanger patient-care centers
continues to increase, the benefits of the Company's practice management
operations will be maximized. The Company will be able to spread
administrative fixed costs and capital expenditures for state-of-the-art
equipment such as CAD/CAM systems over a large number of patient-care centers.
Furthermore, sales can also be enhanced by the Company's use of marketing
programs not generally utilized by practitioners in smaller, independent
practices.
 
  Increase OPNET's Number of O&P Patient-Care Service Members and Contractual
Relationships with Managed Care Organizations. The Company intends to expand
OPNET membership towards the goal of achieving complete nationwide O&P
patient-care coverage. A national network will enable OPNET to negotiate for
contracts with any local, regional or national third-party payor seeking a
single source O&P provider regardless of the payor's geographic scope.
 
  Leverage and Expand the Company's O&P Manufacturing and Distribution
Operations. As the patient-care practice management division of the Company
expands, it can create captive demand for the Company's distribution business.
An increase in the number of OPNET members, to whom preferred purchasing
agreements are offered, can also increase net sales for the Company's
distribution business. The Company's manufacturing division can also benefit
from increased net sales at the distribution division by providing proprietary
products to meet the demand of an expanded captive market. The Company's
manufacturing efforts will focus on the acquisition and/or development of
proprietary patented products such as the Lenox Hill Knee Brace and the
Charleston Bending Brace.
 
PRACTICE MANAGEMENT AND PATIENT-CARE SERVICES
 
 Practice Management Services
 
  The Company provides all senior management, accounting, accounts payable,
payroll, sales and marketing, human resources and management information
systems for its patient-care centers. By providing these services on a
centralized basis, the Company is able to provide such services to its
patient-care centers and practitioners more efficiently and cost-effectively
than if such services had to be generated at each center. The centralization
of these services also permits the Company's certified practitioners to
allocate a greater portion of their time to patient-care activities by
reducing the administrative responsibilities of operating their businesses.
Billing and collections are handled on a decentralized basis, which the
Company believes enhances collectibility.
 
  The Company also develops and implements programs designed to enhance the
efficiency of its clinical practices. Such programs include: (i) sales and
marketing initiatives to attract new-patient referrals by establishing
relationships with physicians, therapists, employers, managed care
organizations, hospitals, rehabilitation centers, outpatient clinics and
insurance companies; (ii) professional management and information systems to
improve efficiencies of administrative and operational functions; (iii)
professional education programs for practitioners emphasizing new developments
in the increasingly sophisticated field of O&P clinical therapy; (iv) the
regional centralization of fabrication and purchasing activities, which
provides overnight access to component parts and products at prices that are
typically 25% lower than traditional procurement methods; and (v) access to
expensive, state-of-the-art equipment which is financially more difficult for
smaller, independent facilities to obtain.
 
  The Company believes that the application of sales and marketing techniques
is a key element of its O&P professional practice management strategy. Due
primarily to the fragmented nature of the industry, the success of an O&P
practice has been largely a function of its local reputation for quality of
care, responsiveness and
 
                                      35
<PAGE>
 
length of service in the community. Individual practitioners have relied
almost exclusively on referrals from local physicians or physical therapists
and typically have not used marketing techniques.
 
 Patient-Care Services
 
  The Company provides O&P patient-care services through 240 owned and
operated O&P patient-care centers in 30 states and the District of Columbia.
Hanger currently employs 373 patient-care practitioners, of whom 280 are
certified practitioners and 35 are candidates for formal certification by the
O&P industry certifying boards. Each of the Company's patient-care centers is
closely supervised by one or more certified practitioners. The balance of the
Company's patient-care practitioners are highly trained technical personnel
who assist in the provision of services to patients and fabricate various O&P
devices.
 
  A patient is referred to one of Hanger's patient-care centers for treatment
upon a determination by the attending physician of a course of treatment for a
patient in need of O&P patient-care services. A Hanger practitioner then
consults with both the referring physician and the patient to formulate the
prescription for, and design of, an orthotic or prosthetic device to meet the
patient's needs.
 
  The fitting process involves several stages in order to successfully achieve
desired functional and cosmetic results. The practitioner creates a cast and
takes detailed measurements of the patient to ensure an anatomically correct
fit. All of the prosthetic devices fitted by Hanger's practitioners are custom
designed and fabricated by skilled practitioners who can balance fit, support
and comfort. Of the orthotic devices provided by Hanger, approximately 75% is
custom designed, fabricated and fitted and the balance are prefabricated but
custom fitted.
 
  Custom devices are fabricated by the Company's skilled technicians using
castings, measurements and designs made by the practitioner. Technicians use
advanced materials and technologies to fabricate a custom device under quality
assurance guidelines. After final adjustments to the device by the
practitioner, the patient is instructed in the use, care and maintenance of
the device. A program of scheduled follow-up and maintenance visits is used to
provide post-fitting treatment, including adjustments or replacements as the
patient's physical condition and lifestyle change.
 
  A substantial portion of Hanger's O&P services involves treatment of a
patient in a non-hospital setting, such as a Hanger patient-care center, a
physician's office, an outpatient clinic or other facility. In addition, O&P
services are increasingly rendered to patients in hospitals, nursing homes,
rehabilitation centers and other alternate-site health care facilities. In a
hospital setting, the practitioner works with a physician to provide either
orthotic devices or temporary prosthetic devices that are later replaced by
permanent prostheses.
 
  The Company also operates in-patient O&P patient-care centers at The Rusk
Institute of Rehabilitation Medicine at the New York University Medical Center
in New York, New York and the Harmarville Rehabilitation Center in Pittsburgh,
Pennsylvania.
 
 OPNET
 
  In 1995, Hanger formed OPNET, a proprietary national preferred provider O&P
referral network serving managed care organizations, including HMOs and PPOs.
OPNET is the only PPO in the United States focusing solely on the O&P market.
Through this network, managed care organizations can contract for O&P services
with any O&P patient-care center in the OPNET network. OPNET has a network of
358 patient-care centers (240 of which are owned and operated by the Company),
serving 291 managed care plans. The Company intends to continue to extend the
network's reach nationwide through acquisitions and marketing. OPNET also
provides incentives to independent O&P service provider members to purchase
their O&P products from the Company. The Company receives upfront annual
payments from practitioners to enter the OPNET network and OPNET does not
receive payments from the managed care participants. Relationships with OPNET
participants have contributed positively to same-store sales growth. In
addition, OPNET has allowed the Company to leverage its existing manufacturing
and distribution infrastructure and increase sales of O&P products
manufactured and/or distributed by the Company. The Company believes that
OPNET's membership enables it to establish significant relationships with
practitioners otherwise not affiliated with the Company.
 
                                      36
<PAGE>
 
  In February 1998, the Company signed a contract with Beverly Enterprises,
Inc. to provide O&P services to patients in approximately 800 nursing homes
and rehabilitation centers throughout the United States. In July 1997, the
Company signed a contract to provide O&P services to FIRST HEALTH Group Corp.,
a major specialty managed care company focused on workers' compensation.
 
MANUFACTURING AND DISTRIBUTION
 
  In addition to on-site fabrication of custom O&P devices incidental to the
services rendered at its O&P patient-care centers, the Company manufactures
O&P components and finished patient-care products for both the O&P industry
and the Company's own patient-care practices. The Company manufactures
components and finished products under various name brands such as Lenox Hill,
CASH Brace, Ortho-Mold and Charleston Bending Brace. The principal products
manufactured are prefabricated and custom-made spinal orthoses as well as
custom-made and off-the-shelf derotation knee braces. The Company distributes
O&P components and finished patient-care products to the O&P industry and to
the Company's own patient-care practices. The Company inventories over 20,000
items, the majority of which are manufactured by other companies and are
distributed by Hanger.
 
  Hanger's distribution capability allows its personnel faster access to the
products needed to fabricate devices for patients. This is accomplished at
competitive prices, as a result of either manufacturing by Hanger or direct
purchases by Hanger from other manufacturers. As a result of faster access to
products, the length of a patient's treatment in the hospital can be reduced,
thereby contributing to health care cost containment.
 
  Marketing of Hanger's manufactured products and distribution services is
conducted on a national basis, primarily through approximately 34 sales
representatives, catalogues and exhibits at industry and medical meetings and
conventions. Hanger directs specialized catalogues to segments of the health
care industry, such as orthopedic surgeons and physical and occupational
therapists. In addition, the Company directs its broad-based marketing to the
O&P industry and the home health care industry.
 
  To provide timely custom fabrication and service to its patients, the
Company employs technical personnel and maintains laboratories at each of its
patient-care centers. The Company uses advanced computer-aided design and
computer-aided machinery (CAD/CAM) technology to produce precise and uniform
products. Hanger has several large, fully-staffed central fabrication
facilities to service its patient-care centers. These strategically located
facilities enable Hanger to fabricate those O&P products that are more easily
produced in larger quantities and in a more cost-effective manner, as well as
serving as an auxiliary production center for products normally fabricated at
individual patient-care centers.
 
ACQUISITIONS
 
  Since 1986, the Company has acquired over 60 businesses in 30 states and the
District of Columbia. In November 1996, Hanger acquired JEH, a Georgia
corporation that operated 96 patient-care centers in 15 states and was the
country's largest distributor of O&P products.
 
  During 1997, the Company acquired nine O&P companies and the remaining 20%
interest of its majority owned subsidiary, Columbia Brace, for an aggregate
consideration, excluding potential earn-out provisions, of $22.5 million.
These O&P companies, which operated 29 patient-care centers and employed 175
persons, had combined net sales of $19.2 million in the year ended December
31, 1997. During the five months ended May 31, 1998, the Company acquired five
O&P companies for an aggregate consideration, excluding potential earn-out
provisions, of approximately $14.9 million. These O&P companies, which operate
25 patient-care centers and employ 110 persons, had combined net sales of
approximately $14.6 million for the year ended December 31, 1997.
 
  The Company continues to be engaged in discussions with several O&P
companies relating to the Company's possible acquisition of their patient-care
practices. The Company's investigations of these businesses are in the
formative stages and no representations can be made as to whether, when or on
what terms such possible acquisitions may be effected.
 
                                      37
<PAGE>
 
  The Company considers both operating and financial factors in evaluating
prospective acquisitions. Operating factors include high standards of
professionalism and patient care, the presence of certified practitioners at
each of its facilities and reputation in the O&P industry. Financial factors
include earnings and cash flow history and the projected benefits of applying
Hanger's operating model to the acquired company's practice. In evaluating
acquisitions in geographic areas where the Company has an established
presence, Hanger targets businesses that complement its existing network of
patient-care centers. In geographic areas where the Company has not yet
established a presence, the Company generally focuses on acquiring strong
regional businesses which have multiple patient-care centers and experienced
practitioners.
 
  The Company's acquisition strategy also includes the retention and support
of the existing management of the acquired company, typically through the use
of employment contracts, non-compete agreements and incentive programs. Upon
the completion of an acquisition, the Company will integrate the business of
the acquired company by: (i) transferring all administrative and financial
management responsibilities to Hanger's corporate headquarters; (ii) providing
all new personnel with compensation and benefit packages and training by the
Company's Human Resources Department; and (iii) providing the management of
the acquired company with instruction on the Company's latest marketing and
sales techniques. Thereafter, the Company will provide the management and
staff of the newly acquired company with financial incentives to induce
greater financial performance.
 
NEW-CENTER DEVELOPMENT
 
  In addition to acquired patient-care centers, the Company develops new
satellite patient-care centers in existing markets with underserved demand for
O&P services. These satellite centers require less capital to develop than
complete O&P centers since the satellite centers usually consist of only a
waiting room and patient fitting rooms, but without a fabrication laboratory
for creating O&P devices. An O&P practitioner will spend one or two days each
week in a satellite center treating those patients who find it inconvenient to
visit the O&P practitioner's primary center.
 
  These satellite centers also tend to receive new patient referrals from
hospitals and physicians located near the newly-developed center, driving new
patient growth and center net sales. While a partial net sales shift occurs
from the O&P practitioner's main center to the satellite center because the
O&P practitioner is now seeing some of the same patients out of a new center,
the additional patient volume in the satellite center increases the O&P
practitioner's overall net sales. If demand for O&P services at a satellite
center increases beyond the ability of the O&P practitioner to service in one
or two days a week, the company will staff the satellite office on a full-time
basis. The Company estimates that the cost of opening a new patient-care
center is approximately $100,000, which includes equipment, leasehold
improvements and working capital. The Company expects a new patient-care
center to reach profitability, as measured by EBITDA, within one year of
opening. No assurance can be given that the Company will be successful in
achieving these start-up and profitability goals with regard to new patient-
care centers.
 
PATIENT REIMBURSEMENT SOURCES
 
  The principal reimbursement sources for Hanger's O&P services are: (i)
private payor/third-party insurer sources which consist of individuals,
private insurance companies, HMOs, PPOs, hospitals, vocational rehabilitation,
workers' compensation and similar sources; (ii) Medicare, which is a federally
funded health insurance program providing coverage for persons aged 65 or
older and certain disabled persons; (iii) Medicaid, which is a health
insurance program jointly funded by federal and state governments providing
coverage for certain persons in financial need, regardless of age, and which
may supplement Medicare benefits for financially needy persons aged 65 or
older; and (iv) the VA, with which Hanger has entered into contracts to
provide O&P services.
 
  Medicare, Medicaid, the VA and certain state agencies, which accounted for
approximately 56.8%, 62.0% and 52.0% of the Company's net sales in 1996, 1997
and the first quarter of 1998, respectively, (based on a sampling of
approximately 75% of the patient-care centers in each period) have set maximum
reimbursement levels for payments for O&P services and products. The health
care policies and programs of these agencies
 
                                      38
<PAGE>
 
have been subject to changes in payment and methodologies during the past
several years. There can be no assurance that future changes will not reduce
reimbursements for O&P services and products from these sources.
 
  The Company provides O&P services to eligible veterans pursuant to several
contracts with the VA. The VA establishes its reimbursement rates for itemized
products and services on a competitive bidding basis. The Company's contracts
with the VA expire in September 1998, with the option to renew for a one- or
two-year period. The contracts, awarded on a non-exclusive basis, establish
the amount of reimbursement to the eligible veteran if the veteran should
choose to use the Company's products and services. The Company has been
awarded VA contracts in the past and expects that it will obtain additional
contracts when its present agreements expire.

COMPETITION
 
  The competition among O&P patient-care centers is primarily for referrals
from physicians, therapists, employers, HMOs, PPOs, hospitals, rehabilitation
centers, outpatient clinics and insurance companies on both a local and
regional basis. The Company believes that distinguishing competitive factors
in the O&P industry are quality and timeliness of patient care and, to a
lesser degree, charges for services. While the Company believes it is one of
the largest suppliers of O&P services in the United States, certain
competitors may have greater financial and personnel resources than Hanger.
The Company competes with others in the industry for trained personnel. To
date, however, Hanger has been able to achieve its staffing needs and has
experienced a relatively low turnover rate of employees. In connection with
its efforts to acquire additional O&P patient-care practices, the Company
encounters competition from several other O&P companies.
 
GOVERNMENT REGULATION
 
 Certification and Licensure
 
  Most states do not require separate licensure for O&P practitioners.
However, several states currently require O&P practitioners to be certified by
an organization such as the ABC.
 
  The ABC conducts a certification program for practitioners and an
accreditation program for patient-care centers. The minimum requirements for a
certified practitioner are a college degree, completion of an accredited
academic program, one to four years of residency at a patient-care center
under the supervision of a certified practitioner and successful completion of
certain examinations. Minimum requirements for an ABC-accredited patient-care
center include the presence of a certified practitioner and specific plant and
equipment requirements. While the Company endeavors to comply with all state
licensure requirements, no assurance can be given that the Company will be in
compliance at all times with these requirements.
 
  Hanger provides services under various contracts to federal agencies. These
contracts are subject to regulations governing federal contracts, including
the ability of the government to terminate for its convenience. Revenue from
such contracts is not material to Hanger.
 
 Medical Device Regulation
 
  The Company manufactures and distributes products that are subject to
regulation as medical devices by the Food and Drug Administration ("FDA")
under the Federal Food, Drug, and Cosmetic Act and accompanying regulations.
The Company believes that the products it manufactures and/or distributes,
including O&P accessories and components, are exempt from FDA's regulations
for premarket clearance or approval requirements and from requirements
relating to "good manufacturing practices" (except for certain recordkeeping
and complaint handling requirements). The Company is required to adhere to
regulations regarding adverse event reporting, and is subject to inspection by
the FDA for compliance with all applicable requirements. Labeling and
promotional materials also are subject to scrutiny by the FDA and, in certain
circumstances, by the Federal Trade Commission. Although the Company has never
been challenged by FDA for noncompliance with FDA requirements, no assurance
can be given that the Company would be found to be or to have been in
compliance at all times. Noncompliance could result in a variety of civil
and/or criminal enforcement actions, which could have a material adverse
effect on the Company's financial condition and results of operations.
 
 Fraud and Abuse
 
  The Company is subject to various federal and state laws pertaining to
health care fraud and abuse, including antikickback laws, false claims laws,
and physician self-referral laws. Violations of these laws are punishable by
criminal and/or civil sanctions, including, in some instances, imprisonment
and exclusion from participation in federal health care programs, including
Medicare, Medicaid, VA health programs and CHAMPUS. The Company has never been
challenged by a governmental authority under any of these laws and believes
that, based on this history, its operations are in material compliance with
such laws. However, because
 
                                      40
<PAGE>
 
of the far-reaching nature of these laws, there can be no assurance that one
or more of the Company's practices would not be required to alter its
practices as a result, or that the occurrence of one or more of these events
would not result in a material adverse effect on the Company's financial
condition and results of operations.
 
  Antikickback Laws. The Company's operations are subject to federal and state
antikickback laws. The Federal Health Care Programs Antikickback Statute
(section 1128B(b) of the Social Security Act) prohibits persons or entities
from knowingly and willfully soliciting, offering, receiving, or paying any
remuneration in return for, or to induce, the referral of persons eligible for
benefits under a Federal Health Care Program (including Medicare, Medicaid,
the VA health programs and CHAMPUS), or the ordering, purchasing or leasing of
items or services that may be paid for, in whole or in part, by a Federal
Health Care Program. The statute may be violated when even one purpose (as
opposed to a primary or sole purpose) of a payment is to induce referrals or
other business. Regulations create a small number of "safe harbors." Practices
which meet all the criteria of an applicable safe harbor will not be deemed to
violate the statute; practices that do not satisfy all elements of a safe
harbor do not necessarily violate the statute, although such practices may be
subject to scrutiny by enforcement agencies. Several states also have
antikickback laws which vary in scope and may apply regardless of whether a
Federal Health Care Program is involved.
 
  These laws may apply to certain of the Company's operations. The Company has
instituted various types of discount programs for individuals or entities that
purchase its products and services. The Company also maintains financial
relationships with individuals and entities who may: (i) purchase the
Company's products and services; (ii) refer patients to Company-owned and
managed O&P patient-care centers; or (iii) receive referrals through OPNET.
These relationships include, among other things, lease arrangements with
hospitals and OPNET participation arrangements. Because some of these
arrangements may not satisfy all elements of an applicable safe harbor, they
could be subject to scrutiny and challenge under one or more such laws.
 
  False Claims Laws. The Company is also subject to federal and state laws
prohibiting individuals or entities from knowingly and willfully presenting,
or causing to be presented, claims for payment to third-party payors
(including Medicare and Medicaid) that are false or fraudulent or are for
items or services not provided as claimed. Each Company-owned and managed O&P
patient-care center is responsible for preparation and submission of
reimbursement claims to third-party payors for items and services furnished to
patients. In addition, Company personnel may, in some instances, provide
advice on billing and reimbursement for the Company's products to purchasers.
While the Company endeavors to ensure that its billing practices comply with
applicable laws, if claims submitted to payors are deemed to be false,
fraudulent, or for items or services not provided as claimed, the Company
could face liability for presenting or causing to be presented such claims.
 
  Physician Self-Referral Laws. The Company is also subject to federal and
state physician self-referral laws. With certain exceptions, the federal
Medicare/Medicaid physician self-referral law (the "Stark" law, section 1877
of the Social Security Act) prohibits a physician from referring Medicare and
Medicaid beneficiaries to an entity for "designated health services,"
including prosthetics, orthotics and prosthetic devices and supplies, if the
physician has either an investment interest in the entity or a compensation
arrangement with the entity. An exception is recognized for referrals made to
a publicly-traded entity in which the physician has an investment interest if,
among other things, the entity had stockholders' equity exceeding $75.0
million for its most recent fiscal year, or on average during the three
previous fiscal years. Although the Company does not provide stock to
referring physicians, the Company's stock is publicly-traded and the Company
is not in a position to know or control whether some referring physicians may
be investors. However, based upon the definition of stockholders' equity set
forth in proposed regulations implementing the Stark law, the Company believes
it has sufficient stockholders' equity to meet the exception that would allow
physician-investors to refer Medicare and Medicaid beneficiaries to Company-
owned and managed O&P patient-care centers in compliance with the Stark law.
 
 Antitrust
 
  The Company is subject to federal and state antitrust laws which prohibit,
among other things, the establishment of ventures that result in certain
anticompetitive conduct. These laws have been applied to the
 
                                      41
<PAGE>
 
establishment of certain networks of otherwise competing health care
providers. In September 1995, the Antitrust Division of the Department of
Justice ("DOJ") issued a business review letter which concluded, in part, that
the description of OPNET voluntarily furnished to the DOJ by the Company "did
not pose any significant competitive issues" and, therefore, DOJ "has no
present intention of challenging [OPNET]" under federal antitrust law.
Although the Company is not able to assure that the continued operation of
OPNET will comply in all respects with the terms specified in the business
review letter, noncompliance with these terms does not mean that the antitrust
authorities or private parties would challenge the conduct, and the Company
believes that the current operation of OPNET is not anticompetitive and
results in significant efficiencies. However, DOJ reserves the right to bring
an investigation or proceeding if it determines that OPNET is anticompetitive
in purpose or effect. There can be no assurance that DOJ will not bring an
investigation or proceeding challenging OPNET (or other aspects of the
Company's operations) under these laws, or that such an investigation or
proceeding would not result in a material adverse effect on the Company's
financial condition and results of operations.
 
PERSONNEL
 
  As of March 31, 1998, the Company employed 1,248 persons, including 1,168
full-time and 80 part-time employees. None of the Company's employees is
subject to a collective bargaining agreement. The Company believes that it has
satisfactory relationships with its employees and strives to maintain these
relationships by offering competitive benefit packages, training programs and
opportunities for advancement.
 
INSURANCE
 
  The Company currently maintains insurance of the type and in the amount
customary in the orthopedic rehabilitation industry, including coverage for
malpractice liability, product liability, workers' compensation and property
damage. Hanger's general liability insurance coverage is at least $500,000 per
incident. Based on the Company's experience and prevailing industry practices,
Hanger believes its coverage is adequate as to risks and amount.

</TABLE>
 
  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will
purchase all shares of Common Stock offered hereby if any such shares are
purchased.
 
  The Company and the Selling Stockholders have been advised by the
Representatives of the Underwriters that the Underwriters propose 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 concession not in excess of $  per share to certain
other dealers. After commencement of the offering, the offering price and
other selling terms may be changed by the Representatives of the Underwriters.
 
  The Company has granted to the Underwriters an option, exercisable not later
than 30 days after the date of this Prospectus, to purchase up to 495,000
additional shares of Common Stock at the public offering price less the
underwriting discounts and commissions set forth on the cover page of this
Prospectus. To the extent that the Underwriters exercise such option, each of
the Underwriters will have a firm commitment to purchase approximately the
same percentage thereof that the number of shares of Common Stock to be
purchased by each of them as shown in the above table bears to 3,300,000, and
the Company will be obligated, pursuant to such option, to sell such shares to
the Underwriters. The Underwriters may exercise such option only to cover
over-allotments made in connection with the sale of the Common Stock offered
hereby. If purchased, the Underwriters will offer such additional shares on
the same terms as those on which the 3,300,000 shares are being offered.
 
  In connection with the offering of the Common Stock, the Underwriters may
engage in transactions that stabilize, maintain or otherwise affect the market
price of the Common Stock. Specifically, the Underwriters may over-allot
shares of the Common Stock in connection with the offering, thereby creating a
short position in the Underwriters' account. Additionally, to cover such short
position or to stabilize the market price of the Common Stock, the
Underwriters may bid for, and purchase, shares of the Common Stock at a level
above that which might otherwise prevail in the open market. The Underwriters
are not required to engage in these activities, and, if commenced, any such
activities may be discontinued at any time. These activities may be effected
on the American Stock Exchange, in the over-the-counter market or otherwise.
The Underwriters also may impose a penalty bid whereby they may reclaim
selling concessions allowed to an Underwriter or dealer, if the Underwriters
repurchase, in stabilizing or covering transactions, shares distributed by
that Underwriter or dealer.
 
  The Underwriting Agreement contains covenants of indemnity and contribution
between the Underwriters and the Company and the Selling Stockholders with
respect to certain civil liabilities, including liabilities under the
Securities Act.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and
 Shareholders of Hanger
 Orthopedic Group, Inc.
 
  We have audited the accompanying consolidated balance sheets of Hanger
Orthopedic Group, Inc. and Subsidiaries as of December 31, 1996 and 1997 and
the related consolidated statements of income, changes in shareholders' equity
and cash flows for each of the three years in the period ended December 31,
1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Hanger
Orthopedic Group, Inc., and Subsidiaries as of December 31, 1996 and 1997, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 1997, in conformity with
generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A--THE COMPANY
 
  Hanger Orthopedic Group, Inc. is one of the nation's largest professional
practice management companies in the O&P rehabilitation industry. In addition
to providing O&P patient-care services through its operating subsidiaries, the
Company also manufactures and distributes components and finished patient-care
products to the O&P industry primarily in the United States. Hanger's largest
subsidiary, Hanger Prosthetics & Orthotics, Inc. formerly known as J.E.
Hanger, Inc., was founded in 1861 by a Civil War amputee and is the oldest
company in the O&P industry in the United States. Orthotics is the design,
fabrication, fitting and supervised use of custom-made braces and other
devices that provide external support to treat musculoskeletal disorders.
Prosthetics is the design, fabrication and fitting of custom-made artificial
limbs.
 
NOTE B--SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation: The consolidated financial statements include
the accounts of the Company and its wholly-owned subsidiaries. All significant
intercompany transactions and balances have been eliminated.
 
  Use of Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Cash and Cash Equivalents: Cash includes currency on hand and demand
deposits with high quality financial institutions. Management considers all
highly liquid investments with original maturities of three months or less at
the date of purchase to be cash equivalents. At various times throughout the
year, the Company maintains cash balances in excess of FDIC limits.
 
  Fair Value of Financial Instruments: At December 31, 1996 and 1997, the
carrying value of financial instruments such as cash and cash equivalents,
trade receivables, trade payables, and debt approximates fair value.
 
  Inventories: Inventories, which consist principally of purchased parts, are
stated at the lower of cost or market using the first-in, first-out (FIFO)
method.
 
  Long-Lived Asset Impairment: The Company reviews its long-lived assets for
impairment on an exception basis whenever events or changes in circumstances
indicate that the carrying amount of the assets may not be recoverable through
future cash flows. If it is determined that an impairment loss has occurred
based on expected cash flows, then the loss is recognized in the income
statement.
 
  Property, Plant and Equipment: Property, plant and equipment are recorded at
cost. The cost and related accumulated depreciation of assets sold, retired or
otherwise disposed of are removed from the respective accounts, and any
resulting gains or losses are included in the statement of income.
Depreciation is computed for financial reporting purposes using the straight-
line method over the estimated useful lives of the related assets ranging from
5 to 20 years. Depreciation expense was approximately $1,136,000, $1,288,000
and $2,173,000 for the years ended December 31, 1995, 1996 and 1997,
respectively and $530,000 and $596,000 for the quarters ended March 31, 1997
and 1998, respectively.
 
  Intangible Assets: Intangible assets, including non-compete agreements, are
recorded based on agreements entered into by the Company and are being
amortized over their estimated useful lives ranging from 5 to 7 years
 
                                      F-7

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
using the straight-line method. Other intangible assets are recorded at cost
and are being amortized over their estimated useful lives of up to 16 years
using the straight-line method. Excess cost over net assets acquired
represents the excess of purchase price over the value assigned to net
identifiable assets of purchased businesses and is being amortized using the
straight-line method over 40 years. Fully amortized intangible assets
amounting to approximately $3,225,000 were removed from the financial
statements at December 31, 1996.
 
  Revenue Recognition: Revenue on the sale of orthotic and prosthetic devices
is recorded when the device is accepted by the patient. Revenues from referral
service contracts is recognized over the term of the contract. Deferred
revenue represents billings made prior to the final fitting and acceptance by
the patient and unearned service contract revenue. Revenue is recorded at its
net realizable value taking into consideration all governmental and
contractual discounts.
 
  Credit Risk: The Company primarily provides services and customized devices
throughout the United States and is reimbursed by the patients' third-party
insurers or governmentally funded health insurance programs. The Company
performs ongoing credit evaluations of its distribution customers. The
accounts receivable are not collateralized. The ability of the Company's
debtors to meet their obligations is dependent upon the financial stability of
the insurers of the Company's customers and future legislation and regulatory
actions. Additionally, the Company maintains reserves for potential losses
from these receivables that historically have been within management's
expectations.
 
  Income Taxes: Income taxes are determined in accordance with Statement of
Financial Accounting Standards ("SFAS") 109, which requires recognition of
deferred income tax liabilities and assets for the expected future tax
consequences of events that have been included in the financial statements or
tax returns. Under this method, deferred income tax liabilities and assets are
determined based on the difference between financial statement and tax bases
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse. SFAS 109 also provides for the
recognition of deferred tax assets if it is more likely than not that the
assets will be realized in future years.
 
  Stock-Based Compensation: Compensation costs attributable to stock option
and similar plans are recognized based on any difference between the quoted
market price of the stock on the date of the grant over the amount the
employee is required to pay to acquire the stock (the intrinsic value method
under Accounting Principles Board Opinion 25). SFAS 123, "Accounting for
Stock-Based Compensation," requires companies electing to continue to use the
intrinsic value method to make pro forma disclosures of net income and
earnings per share as if the fair value based method of accounting had been
applied. The Company has adopted the disclosure only provisions of SFAS 123.
 
  New Accounting Standards: Effective January 1, 1998 the Company adopted the
provisions of SFAS 130, "Reporting Comprehensive Income." SFAS 130 establishes
standards for reporting and display of comprehensive income and its components
in the financial statements. Reclassification of financial statements for
earlier periods provided for comparative purposes is required. The adoption of
SFAS 130 had no effect on the Company's consolidated financial statements.
 
  The Company will adopt the provisions of SFAS 131, "Disclosures about
Segments of an Enterprise and Related Information" effective with the
financial statements for the year ended December 31, 1998. SFAS 131
establishes standards for the way that public business enterprises report
information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports issued to shareholders. It also
establishes standards for related disclosures about products and services,
geographic areas, and major customers. Financial statement disclosures for
prior periods are required to be restated. The Company is in the process of
evaluating the disclosure requirements. The adoption of SFAS 131 affects
disclosure only and will not affect reported earnings, cash flows or financial
position.

  Interim Financial Information: The accompanying unaudited consolidated
interim financial statements have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they
do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the
opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the quarter ended March 31, 1998 are not necessarily
indicative of the results that may be expected for the year ending December
31, 1998.
 
  Reclassifications: Certain previously reported amounts have been
reclassified to conform with the current year presentation.

NOTE D--ACQUISITIONS
 
  During 1996, the Company acquired one orthotic and prosthetic company, J.E.
Hanger, Inc. of Georgia ("JEH"), pursuant to the terms of a Merger Agreement.
As of the acquisition date, JEH, headquartered in Alpharetta, Georgia,
operated 94 patient-care centers and five warehouses located primarily in the
Mid-Atlantic and Southeastern United States. Under the terms of the agreement,
which became effective on November 1, 1996, the Company paid JEH shareholders
$44.0 million in cash and issued 1.0 million shares of Company Common Stock
and paid an additional $1,783,000 to the former JEH shareholders on March 27,
1997 pursuant to provisions in the Merger Agreement calling for a post-closing
adjustment. In addition the Company issued 35,000 warrants to one JEH
noteholder in order to facilitate assumption of this debt under the same terms
and conditions that had existed prior to the acquisition.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  During 1997, the Company acquired nine orthotic and prosthetic companies and
the remaining 20% interest of its majority owned subsidiary, Columbia Brace.
The aggregate purchase price, excluding potential earn-out provisions was
$22,529,200 comprised of $13,715,000 in cash, $8,314,200 in promissory notes
and 64,000 shares of Common Stock of the Company valued at $500,000. The notes
are payable over two to five years with interest rates ranging from 6% to 8%.
The cash portion of these acquisitions was borrowed under the Company's
acquisition loan facility.
 
  All of the above acquisitions have been accounted for as business
combinations in accordance with the purchase method. The results of operations
for these acquisitions are included in the Company's results of operations
from their date of acquisition. Excess cost over net assets acquired in these
acquisitions amounting to approximately $36,699,000 and $20,451,000 in 1996
and 1997, respectively, are amortized using the straight-line method over 40
years.
 
  The following table summarizes the unaudited consolidated pro forma

  The pro forma results do not necessarily represent results which would have
occurred if the acquisitions had taken place at the beginning of each period,
nor are they indicative of the results of future combined operations.
 
  During the first quarter ended March 31, 1998, the Company acquired three
orthotic and prosthetic companies. The aggregate purchase price was
$13,230,000, comprised of $10,475,000 in cash and $2,755,000 in promissory
notes. Excess cost over net assets acquired amounted to approximately
$11,200,000 in connection with these acquisitions. The Company borrowed
$4,000,000 under the Revolving Loan Commitment and $5,000,000 under the
Acquisition Loan Commitment to finance the cash portion of the purchase price.

NOTE E--NET INCOME PER COMMON SHARE
 
  Basic per common share amounts are computed using the weighted average
number of common shares outstanding during the year. Diluted per common share
amounts are computed using the weighted average number of common shares
outstanding during the year and dilutive potential common shares. Dilutive
potential common shares consist of stock options and stock warrants and are
calculated using the treasury stock method.
 
  Earnings per share amounts have been restated in accordance with SFAS 128,
"Earnings Per Share." This restatement did not result in a material change
between diluted per share amounts and amounts previously reported. Earnings
per share are computed as follows:

  In November 1996, the Company entered into a new $90,000,000 Credit
Agreement "Credit Agreement" with a syndication of banks which provided for a:
(i) "A-Term Loan" in the principal amount of $29,000,000; (ii) "B-Term Loan"
in the principal amount of $28,000,000; (iii) $25,000,000 Acquisition Loan
Commitment and; (iv) $8,000,000 Revolving Loan Commitment.
 
  The Credit Agreement provided for an initial commitment fee of 2.625% on the
total $90,000,000 facility and an annual fee of 0.5% per year on the aggregate
unused portion of the Credit Agreement. As of December 31, 1996, the Company
had no outstanding balances on both the Acquisition and Revolving Loan
Commitments.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In November 1996, the Company also entered into a Senior Subordinated Note
Purchase Agreement in the principal amount of $8,000,000 whereby the Company
issued 1,600,000 warrants to noteholders. This transaction resulted in the
Company recording a debt discount of $2,038,500 which was being amortized over
the life of the notes.
 
  The Company used the proceeds of the A-Term Loan, B-Term Loan and Senior
Subordinated Notes to finance the acquisition of JEH and to repay all amounts
then outstanding under the Company's former Revolving credit facility, Senior
Financing Facility, the 8.5% Convertible Junior Subordinated Note and the
8.25% Convertible Junior Subordinate Note. In connection with this
transaction, the Company recorded an extraordinary charge of $138,724
($83,234, net of tax benefit) for the write-off of unamortized discounts and
financing costs, in 1996.
 
  During July and August of 1997, the Company sold 5,750,000 shares of Common
Stock in a underwritten public offering at $11.00 per share resulting in
approximately $58.3 million of net proceeds to the Company.
 
  The Company applied the net proceeds of the public offering to the repayment
of the Senior Subordinated Notes and certain indebtedness outstanding under
the Credit Agreement. Upon repayment of this debt and the Credit Agreement
being substantially modified, the Company incurred an extraordinary loss of
$4.6 million ($2.7 million net of tax benefit).
 
  The modified Credit Agreement is collateralized by substantially all the
assets of the Company, restricts the payment of dividends, and contains
certain affirmative and negative covenants customary in an agreement of this
nature.
 
  The remainder of the A-Term Loan, the $25,000,000 Acquisition Loan
Commitment and the 8,000,000 Revolving Loan Commitment bears base interest at
the Company's option of either LIBOR plus 2.50% or the Bank's prime rate plus
1.50%. The base interest rate is then reduced by 0.25% to 1.25% depending upon
the ratio of the Company's total indebtedness to annual earnings before
interest, taxes, depreciation and amortization. As of December 31, 1997, the
Company had no outstanding balances on both the Acquisition and Revolving Loan
Commitments.
 
  The remainder of the B-Term Loan bears base interest at the Company's option
of either LIBOR plus 2.75% or the Bank's prime rate plus 1.75%. The base
interest rate is then reduced by 0.25% to 1.25% depending upon the ratio of
the Company's total indebtedness to annual earnings before interest, taxes,
depreciation and amortization.
 
  The Company has entered into an interest rate swap agreement to reduce the
impact of changes in interest rates on amounts outstanding on its Credit
Agreement. At December 31, 1997, the Company had an outstanding interest rate
swap agreement with a commercial bank, having a total notional principal
amount of up to $26,950,000. The agreement effectively minimizes the Company's
base interest rate exposure between a floor of 5.32% and a cap of 7%. The
interest rate swap agreement matures on September 30, 1999. The Company is
exposed to credit loss in the event of non-performance by the other party to
the interest rate swap agreement. However, the Company does not anticipate
non-performance by the counterparties.

  For Federal tax purposes at December 31, 1997, the Company has available
approximately $789,000 of net operating loss carryforwards expiring from 1998
through 2007 and are subject to a limitation in their utilization of
approximately $149,000 per year as a result of several changes in shareholder
control.
 
  At December 31, 1995, the Company evaluated the realizability of the state
net operating losses and, based upon projections of taxable income by state,
concluded that a valuation allowance was not necessary. The remaining balance
of the deferred tax assets should be realized through future taxable income
and the reversal of taxable temporary differences.
 
NOTE I--DEFERRED COMPENSATION
 
  In conjunction with the JEH acquisition, the Company assumed the unfunded
deferred compensation plan that had been established for certain key JEH
officers. The plan accrues benefits ratably over the period of active
employment from the time the contract is entered into to the time the
participant retires. Participation had been determined by JEH's Board of
Directors. The Company has purchased individual life insurance contracts with
respect to each employee covered by this plan. The Company is the owner and
beneficiary of the insurance contracts. The accrual related to the deferred
compensation arrangements amounted to approximately $1,985,000 and $2,099,000
at December 31, 1996 and 1997, respectively.
 
NOTE J--COMMITMENTS AND CONTINGENT LIABILITIES
 
  The Company is engaged in legal proceedings in the normal course of
business. The Company believes that any unfavorable outcome from these suits
not covered by insurance would not have a material adverse effect on the
financial statements of the Company.

  Rent expense was approximately $2,144,000, $2,554,000 and $4,509,000 for the
years ended December 31, 1995, 1996 and 1997, respectively.
 
NOTE L--PENSION AND PROFIT SHARING PLANS
 
  Previously, the Company had a 401(k) Saving and Retirement Plan (the "Plan")
available to all employees of J.E. Hanger, Inc. ("J.E. Hanger"), a wholly-
owned subsidiary of the Company. The Company matched the participant's
contributions and made discretionary matching contributions. On January 1,
1993, the Company froze the Plan such that no new employees of J.E. Hanger
were able to participate. On December 31, 1995, the Company terminated the
Plan. There was no employer contribution made to the Plan in 1995.
 
  The Company maintains a separate defined contribution profit sharing and
401(k) plan ("JEH Plan") covering all the employees of JEH, a wholly-owned
subsidiary of the Company acquired November 1, 1996. On this date, the Company
froze the JEH Plan such that no new employees of JEH were able to participate.
The Company did not incur any expense in connection with this plan during the
years ended December 31, 1996 and 1997. On January 1, 1998 the JEH Plan was
merged into the Company's 401(k) Savings and Retirement Plan.
 
  The Company maintains a 401(k) Savings and Retirement plan to cover all of
the employees of the Company. The Company may make discretionary
contributions. Under this 401(k) plan, employees may defer such amounts of
their compensation up to the levels permitted by the Internal Revenue Service.
The Company has not made any contributions to this plan.
 
NOTE M--REDEEMABLE PREFERRED STOCKS
 
  The Company has 10,000,000 authorized shares of preferred stock, par value
$0.01 per share, which may be issued in various classes with different
characteristics.
 
  The 300 issued and outstanding shares of non-voting, non-convertible Class C
preferred stock have an aggregate liquidation value equal to $150,000 plus
accrued dividends at 9% and are required to be redeemed on February 1, 2000.
Accrued dividends at December 31, 1996 and 1997, were $616,124 and $642,176,
respectively.
 
  The 100,000 authorized shares of Class F preferred stock, accrues dividends
cumulatively at 16.5% and is required to be redeemed prior to any other class
of preferred stock, before September 1998, for the aggregate liquidation value
of $1,000 per share, plus accrued dividends. As of December 31, 1996 and 1997,
none of the Class F preferred stock was issued or outstanding.

NOTE N--WARRANTS AND OPTIONS
 
WARRANTS
 
  In November 1990, the Company entered into a $2,450,000 Note which required
the Company, based on certain repayment provisions, to issue to an affiliate
in 1991 warrants to purchase 297,883 and 322,699 shares of common stock at
$4.16 and $7.65 per share, respectively. These warrants are exercisable
through December 31, 2001. In May 1996, 71,969 warrants were exercised at
$4.16 per share which resulted in the issuance of 11,332 shares. In May 1997,
77,964 warrants were exercised at $7.65 per share which resulted in the
issuance of 11,694 shares.
 
  In November 1996, the Company issued warrants for 1.6 million shares of
common stock to the holders of the Senior Subordinated Notes. In August 1997,
the Company repaid these Notes with the proceeds from the public offering. In
accordance with the Senior Subordinate Note Agreement, 880,000 warrants were
terminated. The remaining 720,000 warrants provide that the noteholders may
purchase 418,365 shares and 301,635 shares for $4.01 and $6.375, respectively.
The warrants are exercisable through November 1, 2004.
 
  In November 1996, the Company issued warrants for 35,000 shares of common
stock as an incentive to one JEH noteholder to allow the notes to be assumed
by the Company under the same terms and conditions that had existed prior to
the acquisition. In January 1997, the noteholder exercised the warrants and
purchased 35,000 shares of common stock for $2.44 per share.
 
OPTIONS
 
  Under the Company's 1991 Stock Option Plan ("SOP"), 1,500,000 shares of
Common Stock are authorized for issuance under options that may be granted to
employees. The number of shares available for grant at December 31, 1996 was
113,501. There were no shares available for grant at December 31, 1997. Under
the SOP, options may be granted at an exercise price not less than the fair
market value of the Common Stock on the date of grant. Vesting and expiration
periods are established by the Compensation Committee of the Board of
Directors and generally vest three years following grant and generally expire
eight to ten years after grant.
 
  Under the Company's 1993 Non-Employee Director Stock Option Plan, 250,000
shares of Common Stock are authorized for issuance to directors of the Company
who are not employed by the Company or any affiliate of the Company. Under
this plan, an option to purchase 5,000 shares of Common Stock is granted
automatically on an annual basis to each eligible director on the third
business day following the date of each Annual Meeting of Stockholders of the
Company at which the eligible director is elected. The exercise price of each
option will be equal to 100% of the fair market value of the Common Stock on
the date of grant. Each option will vest at the rate of 25% each year for the
first four years after the date of grant of the option and each such option
expires ten years from the date of grant; provided, however, that in the event
of termination of a director's service other than by reason of total and
permanent disability or death, then the outstanding options of such holder
expires three months after such termination. Outstanding options remain
exercisable for one year after termination of service by reason of total and
permanent disability or death. The number of shares that remain available for
grant at December 31, 1996 and 1997 were 130,000 and 95,000, respectively.
 
  In addition to the SOP, non-qualified options may be granted with exercise
prices that are less than the current market value. Accordingly, compensation
expense for the difference between current market value and exercise price is
recorded at the date of grant.

  The Company applies APB Opinion 25 "Accounting for Stock Issued to
Employees," and related Interpretations in accounting for its plans.
Historically, the Company granted stock options at exercise prices equal to
the fair market value of the stock on the date of grant for fixed stock
options. Accordingly, no compensation cost has been recognized for its fixed
stock option plans. Had compensation cost for the Company's stock-based
compensation plans been determined based on the fair value at the grant dates
for awards under those plans consistent with the method of SFAS 123,
"Accounting for Stock-Based Compensations" the Company's net income and
earnings per share would have been reduced to the unaudited pro forma amounts

  The pro forma information regarding net income and earnings per share is
required by SFAS 123, and has been determined as if the Company had accounted
for its employee stock options under the fair value method of SFAS 123. The
fair value for these options was estimated at the date of grant using a Black-
Scholes option pricing model with the following weighted average assumptions
for 1995, 1996 and 1997:
 
<TABLE>

</TABLE>
 
  The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in
the subjective input assumptions can materially affect the fair value
estimate, in management's opinion, the existing models do not necessarily
provide a reliable single measure of the fair value of its employee stock
options.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Hanger is permitted by Delaware law and required by its Certificate of
Incorporation and its By-laws to indemnify any director or officer or former
director of officer against all expenses and liabilities reasonably incurred
by him in connection with any legal action in which such person is involved by
reason of his position with Hanger unless he is adjudged liable for negligence
or misconduct in the performance of his duties as a director or officer. If
any such action is settled, Hanger will provide indemnification only if the
Board of Directors approves such settlement after receiving an opinion of
counsel for Hanger that settlement is in Hanger's best interest.
 
  Reference is made to Section 8 of the Underwriting Agreement (included
herein as a part of Exhibit 1) which contains provisions for the
indemnification by the Underwriters of Hanger and directors, officers and
controlling persons of Hanger and the Selling Stockholders under certain
circumstances.

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes:
 
    (1) The undersigned registrant hereby undertakes that, for purposes of
  determining any liability under the Securities Act of 1933, each filing of
  the registrant's annual report pursuant to Section 13(a) or 15(d) of the
  Securities Exchange Act of 1934 (and, where applicable, each filing of an
  employee benefit plan's annual report pursuant to Section 15(d) of the
  Securities Exchange Act of 1934) that is incorporated by reference in the
  registration statement 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 that initial bona fide
  offering thereof.
 
                                     II-1
<PAGE>
 
    (2) For purposes of determining any liability under the Securities Act of
  1933, 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 the
  registration statement as of the time it was declared effective.
 
    (3) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.

     As the Representatives, you have advised the Company and the Selling

Option Shares (to the extent the aforementioned option is exercised) are herein
collectively called the "Shares."

     In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:

     1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE SELLING
          -------------------------------------------------------------
          STOCKHOLDERS.
          ------------ 

          (a) The Company represents and warrants to each of the Underwriters
     and the Selling Stockholders as follows:

          (i) A registration statement on Form S-3 (File No. ________) with
     respect to the Shares has been carefully prepared by the Company in
     conformity with the requirements of the Securities Act of 1933, as amended
     (the "Act"), and the Rules and Regulations (the "Rules and Regulations") of
     the Securities and Exchange Commission (the "Commission") thereunder and
     has been filed with the Commission. Form S-3 is available for use by the
     Company. Copies of such registration statement, including any amendments
     thereto, the preliminary prospectuses (meeting the requirements of the
     Rules and Regulations) contained therein and the exhibits, financial
     statements and schedules, as finally amended and revised, have heretofore
     been delivered by the Company to you. Such registration statement, together
     with any registration statement filed by the Company pursuant to Rule
     462(b) of the Act, herein referred to as the "Registration Statement,"
     which shall be deemed to include all information omitted therefrom in
     reliance upon Rule 430A and contained in the Prospectus referred to below,
     has become effective under the Act and no post-effective amendment to the
     Registration Statement has been filed as of the date of this Agreement.
     "Prospectus" means (a) the form of prospectus first filed with the
     Commission pursuant to Rule 424(b) or (b) the last preliminary prospectus
     included in the Registration Statement filed prior to the time it becomes
     effective or filed pursuant to Rule 424(a) under the Act that is delivered
     by the Company to the Underwriters for delivery to purchasers of the
     Shares, together with the term sheet or abbreviated term sheet filed with
     the Commission pursuant to Rule 424(b)(7) under the Act. Each preliminary
     prospectus included in the Registration Statement prior to the time it
     becomes effective is herein referred to as a "Preliminary Prospectus." Any
     reference herein to the Registration Statement, any Preliminary Prospectus
     or to the Prospectus shall be deemed to refer to and include any documents
     incorporated by reference therein, and, in the case of any reference herein
     to any Prospectus, also shall be deemed to include any documents
     incorporated by reference therein, and any supplements or amendments
     thereto, filed with the Commission after the date of filing of the
     Prospectus under Rules 424(b) or 430A, and prior to the termination of the
     offering of the Shares by the Underwriters.

          (ii)  The Company has been duly organized and is validly existing as a
     corporation in good standing under the laws of the State of Delaware, with
     corporate power and authority to own or lease its properties and conduct
     its business as described in 

                                       2
<PAGE>
 
     the Registration Statement. Each of the subsidiaries of the Company as
     listed in Exhibit A hereto (collectively, 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 Registration Statement. The Subsidiaries are the only
     subsidiaries, direct or indirect, of the Company. 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. The outstanding shares of capital stock of each of the
     Subsidiaries have been duly authorized and validly issued, are fully paid
     and non-assessable and are owned by the Company or another Subsidiary free
     and clear of all liens, encumbrances and equities and claims; and no
     options, warrants or other rights to purchase, agreements or other
     obligations to issue or other rights to convert any obligations into shares
     of capital stock or ownership interests in the Subsidiaries are
     outstanding.

          (iii)  The outstanding shares of Common Stock of the Company,
     including all Shares to be sold by the Selling Stockholders, have been duly
     authorized and validly issued and are fully paid and non-assessable; the
     portion of the Shares to be issued and sold by the Company have been duly
     authorized and when issued and paid for as contemplated herein will be
     validly issued, fully paid and non-assessable; and no preemptive rights of
     stockholders exist with respect to any of the Shares or the issue and sale
     thereof. Neither the filing of the Registration Statement nor the offering
     or sale of the Shares as contemplated by this Agreement gives rise to any
     rights, other than those which have been waived or satisfied, for or
     relating to the registration of any shares of Common Stock.

          (iv)  The information set forth under the caption "Capitalization" in
     the Prospectus is true and correct. All of the Shares conform to the
     description thereof contained in the Registration Statement. The form of
     certificates for the Shares conforms to the corporate law of the
     jurisdiction of the Company's incorporation.

          (v)  The Commission has not issued an order preventing or suspending
     the use of any Prospectus relating to the proposed offering of the Shares
     nor instituted proceedings for that purpose. The Registration Statement
     contains, and the Prospectus and any amendments or supplements thereto will
     contain, all statements which are required to be stated therein by, and
     will conform, to the requirements of the Act and the Rules and Regulations.
     The documents incorporated by reference in the Prospectus, at the time
     filed with the Commission, conformed in all material respects to the
     requirements of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act"), or the Act, as applicable, and the rules and regulations
     of the Commission thereunder. The Registration Statement and any amendment
     thereto do not contain, and will not contain, any untrue statement of a
     material fact and do not omit, and will not omit, to state any material
     fact required to be stated therein or necessary to make the statements
     therein not misleading. The Prospectus and any amendments and supplements
     thereto do not contain, and will not contain, any untrue statement of
     material fact; and do not omit, and will not omit, to 

                                       3
<PAGE>
 
     state any material fact required to be stated therein or necessary to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading; provided, however, that the Company makes no
     representations or warranties as to information contained in or omitted
     from the Registration Statement or the Prospectus, or any such amendment or
     supplement, in reliance upon, and in conformity with, written information
     furnished to the Company by or on behalf of any Underwriter through the
     Representatives, specifically for use in the preparation thereof.

          (vi)  The consolidated financial statements of the Company and the
     Subsidiaries, together with related notes and schedules as set forth or
     incorporated by reference in the Registration Statement, present fairly the
     financial position and the results of operations and cash flows of the
     Company and the consolidated Subsidiaries, at the indicated dates and for
     the indicated periods. Such financial statements and related schedules have
     been prepared in accordance with generally accepted principles of
     accounting, consistently applied throughout the periods involved, except as
     disclosed herein, and all adjustments necessary for a fair presentation of
     results for such periods have been made. The summary financial and
     statistical data included or incorporated by reference in the Registration
     Statement presents fairly the information shown therein and such data has
     been compiled on a basis consistent with the financial statements presented
     therein and the books and records of the company. The pro forma financial
     statements and other pro forma financial information included in the
     Registration Statement and the Prospectus present fairly the information
     shown therein, have been prepared in accordance with the Commission's rules
     and guidelines with respect to pro forma financial statements, have been
     properly compiled on the pro forma bases described therein, and, in the
     opinion of the Company, the assumptions used in the preparation thereof are
     reasonable and the adjustments used therein are appropriate to give effect
     to the transactions or circumstances referred to therein.

          (vii)  Coopers & Lybrand L.L.P., who have certified certain of the
     financial statements filed with the Commission as part of, or incorporated
     by reference in, the Registration Statement, are independent public
     accountants as required by the Act and the Rules and Regulations.

          (viii)  There is no action, suit, claim or proceeding pending or, to
     the knowledge of the Company, threatened against the Company or any of the
     Subsidiaries before any court or administrative agency or otherwise which
     if determined adversely to the Company or any of its Subsidiaries might
     result in any material adverse change in the earnings, business,
     management, properties, assets, rights, operations, condition (financial or
     otherwise) or prospects of the Company and of the Subsidiaries taken as a
     whole or to prevent the consummation of the transactions contemplated
     hereby, except as set forth in the Registration Statement.

          (ix)  The Company and the Subsidiaries have good and marketable title
     to all of the properties and assets reflected in the financial statements
     (or as described in the Registration Statement) hereinabove described,
     subject to no lien, mortgage, pledge, 

                                       4
<PAGE>
 
     charge or encumbrance of any kind except those reflected in such financial
     statements (or as described in the Registration Statement) or which are not
     material in amount. The Company and the Subsidiaries occupy their leased
     properties under valid and binding leases conforming in all material
     respects to the description thereof set forth or incorporated by reference
     in the Registration Statement.

          (x)  The Company and the Subsidiaries have filed all Federal, State,
     local and foreign income tax returns which have been required to be filed
     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 have become
     due and are not being contested in good faith. All tax liabilities have
     been adequately provided for in the financial statements of the Company and
     the Company does not know of any actual or proposed additional material tax
     assessments.

          (xi)  Since the respective dates as of which information is given in
     the Registration Statement, as it may be amended or supplemented, there has
     not been any material adverse change or any development involving a
     prospective material adverse change in or affecting the earnings, business,
     management, properties, assets, rights, operations, condition (financial or
     otherwise), or prospects of the Company and its Subsidiaries taken as a
     whole, whether or not occurring in the ordinary course of business, and
     there has not been any material transaction entered into or any material
     transaction that is probable of being entered into by the Company or the
     Subsidiaries, other than transactions in the ordinary course of business
     and changes and transactions described in the Registration Statement, as it
     may be amended or supplemented. The Company and the Subsidiaries have no
     material contingent obligations which are not disclosed in the Company's
     financial statements which are included in the Registration Statement.

          (xii)  Neither the Company nor any of the Subsidiaries is, or with the
     giving of notice or lapse of time or both, will be, in violation of or in
     default under its Charter or By-Laws or under any agreement, lease,
     contract, indenture or other instrument or obligation to which it is a
     party or by which it, or any of its properties, is bound and which default
     is of material significance in respect of the condition, financial or
     otherwise of the Company and its Subsidiaries taken as a whole or the
     business, management, properties, assets, rights, operations, condition
     (financial or otherwise) or prospects of the Company and the Subsidiaries
     taken as a whole. The execution and delivery of this Agreement and the
     consummation of the transactions herein contemplated and the fulfillment of
     the terms hereof will not conflict with or result in a breach of any of the
     terms or provisions of, or constitute a default under, any indenture,
     mortgage, deed of trust or other agreement or instrument to which the
     Company or any Subsidiary is a party, or of the Charter or By-Laws of the
     Company or any order, rule or regulation applicable to the Company or any
     Subsidiary of any court or of any regulatory body or administrative agency
     or other governmental body having jurisdiction.

                                       5
<PAGE>
 
          (xiii)  Each approval, consent, order, authorization, designation,
     declaration or filing by or with any regulatory, administrative or other
     governmental body necessary in connection with the execution and delivery
     by the Company of this Agreement and the consummation of the transactions
     herein contemplated (except such additional steps as may be required by the
     Commission, the National Association of Securities Dealers, Inc. (the
     "NASD") or such additional steps as may be necessary to qualify the Shares
     for public offering by the Underwriters under state securities or Blue Sky
     laws) has been obtained or made and is in full force and effect.

          (xiv)  The Company and each of the Subsidiaries holds all material
     licenses, certificates and permits from governmental authorities which are
     necessary to the conduct of their businesses; and neither the Company nor
     any of the Subsidiaries has infringed any patents, patent rights, trade
     names, trademarks or copyrights, which infringement is material to the
     business of the Company and the Subsidiaries taken as a whole. The Company
     knows of no material infringement by others of patents, patent rights,
     trade names, trademarks or copyrights owned by or licensed to the Company.

          (xv)  Neither the Company, nor to the Company's best knowledge, any of
     its affiliates, has taken or may take, directly or indirectly, any action
     designed to cause or result in, or which has constituted or which might
     reasonably be expected to constitute, the stabilization or manipulation of
     the price of the shares of Common Stock to facilitate the sale or resale of
     the Shares.

          (xvi)  Neither the Company nor any Subsidiary is an "investment
     company" within the meaning of such term under the Investment Company Act
     of 1940 and the rules and regulations of the Commission thereunder.

          (xvii)  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 generally accepted accounting
     principles 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.
     
          (xviii)  The Company and each of its Subsidiaries carry, or are
     covered by, insurance in such amounts and covering such risks as is
     adequate for the conduct of their respective businesses and the value of
     their respective properties and as is customary for companies engaged in
     similar industries.

          (xix)  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 ("ERISA"); no "reportable event" (as defined in
     ERISA) has occurred with respect to any "pension 

                                       6
<PAGE>
 
     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) Sections 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.

          (xx)  To the Company's knowledge, there are no affiliations or
     associations between any member of the NASD and any of the Company's
     officers, directors or 5% or greater securityholders, except as set forth
     in the Registration Statement.

          (xxi)  Neither the Company nor any Subsidiary has engaged in any
     activities which are prohibited, or are cause for civil penalties or
     mandatory or permissive exclusion from Medicare or Medicaid, under Sections
     1320a-7, 1320a-7a, 1320a-7b, or 1395nn of Title 42 of the United States
     Code, the federal CHAMPUS statute, or the regulations promulgated pursuant
     to such statutes or regulations or related state or local statutes or which
     are prohibited by any private accrediting organization from which the
     Company or any of its Subsidiaries seeks accreditation or by generally
     recognized professional standards of care or conduct. Neither the Company
     nor to the knowledge of the Company any other person who has a direct or
     indirect ownership or control interest in the Company or any Subsidiary or
     who is an officer, director, agent or managing employee of the Company or
     any Subsidiary: (1) has had a civil monetary penalty assessed against it
     under Section 1128A of the Social Security Act ("SSA"); (2) has been
     excluded from participation under the Medicare program or a Federal Health
     Care Program (as that term is defined in SSA Section 1128(B)(f)); or (3)
     has been convicted (as that term is defined in 42 C.F.R. (S) 1001.2) of any
     of the categories of offenses described in SSA Section 1128(a) and (b)(1),
     (2) and (3).

          (b)  Each of the Selling Stockholders severally represents and
     warrants as follows:

          (i)  Such Selling Stockholder now has and at the Closing Date (as such
     date is hereinafter defined) will have good and valid title to the Firm
     Shares to be sold by such Selling Stockholder, free and clear of any liens,
     encumbrances, equities and claims, and full right, power and authority to
     effect the sale and delivery of such Firm Shares; and upon the delivery of,
     against payment for, such Firm Shares pursuant to this Agreement, the
     Underwriters (assuming that they are bona fide purchasers within the
     meaning of the Uniform Commercial Code) will acquire good and valid title
     thereto, free and clear of any liens, encumbrances, equities and claims.

          (ii)  Such Selling Stockholder has full right, power and authority to
     execute and deliver this Agreement, the Power of Attorney, and the Custody
     Agreement referred to below and to perform its obligations under such
     Agreements. The execution and delivery 

                                       7
<PAGE>
 
     of this Agreement and the consummation by such Selling Stockholder of the
     transactions herein contemplated and the fulfillment by such Selling
     Stockholder of the terms hereof will not require any consent, approval,
     authorization, or other order of any court, regulatory body, administrative
     agency or other governmental body (except as may be required under the Act,
     state securities laws or Blue Sky laws or the rules and regulations of the
     National Association of Securities Dealers, Inc.) and will not result in a
     material breach of any of the terms and provisions of, or constitute a
     material default under, organizational documents of such Selling
     Stockholder, if not an individual, or any indenture, mortgage, deed of
     trust or other agreement or instrument to which such Selling Stockholder is
     a party, or of any order, rule or regulation applicable to such Selling
     Stockholder of any court or of any regulatory body or administrative agency
     or other governmental body having jurisdiction.

          (iii)  Such Selling Stockholder has not taken and will not take,
     directly or indirectly, any action 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 and, other than as permitted by the Act, the Selling Stockholder
     will not distribute any prospectus or other offering material in connection
     with the offering of the Shares.

          (iv)  Without having undertaken to determine independently or
     independently verify the accuracy or completeness of either the
     representations and warranties of the Company contained herein or the
     information contained in the Registration Statement, such Selling
     Stockholder has no reason to believe that the representations and
     warranties of the Company contained in this Section 1(a) are not true and
     correct, is familiar with the Registration Statement and has no knowledge
     of any material fact, condition or information not disclosed in the
     Registration Statement which has adversely affected or is reasonably likely
     to adversely affect the business of the Company and its Subsidiaries taken
     as a whole; and the sale of the Firm Shares by such Selling Stockholder
     pursuant hereto is not prompted by any material information concerning the
     Company or any of the Subsidiaries which is not set forth in the
     Registration Statement or the documents incorporated by reference therein
     and which is reasonably likely to have an affect on the business of the
     Company and its Subsidiaries, taken as a whole. The information pertaining
     to such Selling Stockholder under the caption "Principal and Selling
     Stockholders" in the Prospectus is complete and accurate in all material
     respects.

     2.   PURCHASE, SALE AND DELIVERY OF THE FIRM SHARES.
          ---------------------------------------------- 

          (a)  On the basis of the representations, warranties and covenants
     herein contained, and subject to the conditions herein set forth, the
     Sellers agree to sell to the Underwriters and each Underwriter agrees,
     severally and not jointly, to purchase, at a price of $______ per share,
     the number of Firm Shares set forth opposite the name of each Underwriter
     in Schedule I hereof, subject to adjustments in accordance with Section 9
     hereof. The number of Firm Shares to be purchased by each Underwriter from
     each Seller shall be as nearly as practicable in the same proportion to the
     total number of 

                                       8
<PAGE>
 
     Firm Shares being sold by each Seller as the number of Firm Shares being
     purchased by each Underwriter bears to the total number of Firm Shares to
     be sold hereunder. The obligations of the Company and of each of the
     Selling Stockholders shall be several and not joint.

          (b)  Certificates in negotiable form for the total number of the
     Shares to be sold hereunder by the Selling Stockholders have been placed in
     custody with ChaseMellon Bank as custodian (the "Custodian") pursuant to
     the Custody Agreement executed by each Selling Stockholder for delivery of
     all Firm Shares to be sold hereunder by the Selling Stockholders. Each of
     the Selling Stockholders specifically agrees that the Firm Shares
     represented by the certificates held in custody for the Selling
     Stockholders under the Custody Agreement are subject to the interests of
     the Underwriters hereunder, that the arrangements made by the Selling
     Stockholders for such custody are to that extent irrevocable, and that the
     obligations of the Selling Stockholders hereunder shall not be terminable
     by any act or deed of the Selling Stockholders (or by any other person,
     firm or corporation including the Company, the Custodian or the
     Underwriters) or by operation of law (including the death of an individual
     Selling Stockholder or the dissolution of a Selling Stockholder that is not
     an individual) or by the occurrence of any other event or events, except as
     set forth in the Custody Agreement. If any such event (other than as
     provided in the Custody Agreement) should occur prior to the delivery to
     the Underwriters of the Firm Shares hereunder, certificates for the Firm
     Shares shall be delivered by the Custodian in accordance with the terms and
     conditions of this Agreement as if such event has not occurred. The
     Custodian is authorized to receive and acknowledge receipt of the proceeds
     of sale of the Shares held by it against delivery of such Shares.

          (c)  Payment for the Firm Shares to be sold hereunder is to be made by
     wire transfer of immediately available funds to an account designated by
     the Company for the shares to be sold by it and to an account designated by
     ChaseMellon Bank "as Custodian" for the shares to be sold by the Selling
     Stockholders, in each case against delivery of certificates therefor to the
     Representatives for the several accounts of the Underwriters. Such payment
     and delivery are to be made at the offices of BT Alex. Brown Incorporated,
     One South Street, Baltimore, Maryland, at 10:00 a.m., Baltimore time, on
     the third business day after the date of this Agreement or at such other
     time and date not later than five business days thereafter as you and the
     Company shall agree upon, such time and date being herein referred to as
     the "Closing Date." (As used herein, "business day" means a day on which
     the New York Stock Exchange is open for trading and on which banks in New
     York are open for business and are not permitted by law or executive order
     to be closed.) The certificates for the Firm Shares will be delivered in
     such denominations and in such registrations as the Representatives request
     in writing not later than the second full business day prior to the Closing
     Date, and will be made available for inspection by the Representatives at
     least one business day prior to the Closing Date.

          (d)  In addition, on the basis of the representations and warranties
     herein contained and subject to the terms and conditions herein set forth,
     the Company hereby

                                       9
<PAGE>
 
     grants an option to the several Underwriters to purchase the Option Shares
     at the price per share as set forth in the first paragraph of this Section
     2. The option granted hereby may be exercised in whole or in part by giving
     written notice (i) at any time before the Closing Date and (ii) only once
     thereafter within 30 days after the date of this Agreement, by you, as
     Representatives of the several Underwriters, to the Company setting forth
     the number of Option Shares as to which the several Underwriters are
     exercising the option, the names and denominations in which the Option
     Shares are to be registered and the time and date at which such
     certificates are to be delivered. The time and date at which certificates
     for Option Shares are to be delivered shall be determined by the
     Representatives but shall not be earlier than three nor later than 10 full
     business days after the exercise of such option, nor in any event prior to
     the Closing Date (such time and date being herein referred to as the
     "Option Closing Date"). If the date of exercise of the option is three or
     more days before the Closing Date, the notice of exercise shall set the
     Closing Date as the Option Closing Date. The number of Option Shares to be
     purchased by each Underwriter shall be in the same proportion to the total
     number of Option Shares being purchased as the number of Firm Shares being
     purchased by such Underwriter bears to ____________, adjusted by you in
     such manner as to avoid fractional shares. The option with respect to the
     Option Shares granted hereunder may be exercised only to cover over-
     allotments in the sale of the Firm Shares by the Underwriters. You, as
     Representatives of the several Underwriters, may cancel such option at any
     time prior to its expiration by giving written notice of such cancellation
     to the Company. To the extent, if any, that the option is exercised,
     payment for the Option Shares shall be made on the Option Closing Date by
     wire transfer of immediately available funds to an account designated by
     the Company against delivery of certificates therefor at the offices of BT
     Alex. Brown Incorporated, One South Street, Baltimore, Maryland.

         (e)  If on the Closing Date, any Selling Stockholder fails to sell the
     Firm Shares which such Selling Stockholder has agreed to sell on such date
     as set forth in Schedule II hereto, the Company agrees that it will sell or
                     -----------                                                
     arrange for the sale of that number of shares of Common Stock to the
     Underwriters which represents Firm Shares which such Selling Stockholder
     has failed to so sell, as set forth in Schedule II hereto, or such lesser
                                            -----------                       
     number as may be requested by the Representatives.

     3.   OFFERING BY THE UNDERWRITERS.
          ---------------------------- 

          It is understood that the several Underwriters are to make a public
     offering of the Firm Shares as soon as the Representatives deem it
     advisable to do so. The Firm Shares are to be initially offered to the
     public at the initial public offering price set forth in the Prospectus.
     The Representatives may from time to time thereafter change the public
     offering price and other selling terms. To the extent, if at all, that any
     Option Shares are purchased pursuant to Section 2 hereof, the Underwriters
     will offer them to the public on the foregoing terms.

                                       10
<PAGE>
 
          It is further understood that you will act as the Representatives for
     the Underwriters in the offering and sale of the Shares in accordance with
     a Master Agreement Among Underwriters entered into by you and the several
     other Underwriters.

     4.   COVENANTS OF THE COMPANY AND THE SELLING STOCKHOLDERS.
          ----------------------------------------------------- 

          (a)  The Company covenants and agrees with the several Underwriters
     and each of the Selling Stockholders that:

          (i)  The Company will (A) use its best efforts to cause the
     Registration Statement to become effective or, if the procedure in Rule
     430A of the Rules and Regulations is followed, to prepare and timely file
     with the Commission under Rule 424(b) of the Rules and Regulations a
     Prospectus in a form approved by the Representatives containing information
     previously omitted at the time of effectiveness of the Registration
     Statement in reliance on Rule 430A of the Rules and Regulations, (B) not
     file any amendment to the Registration Statement or supplement to the
     Prospectus or document incorporated by reference therein of which the
     Representatives shall not previously have been advised and furnished with a
     copy or to which the Representatives shall have reasonably objected in
     writing or which is not in compliance with the Rules and Regulations, and
     (C) file on a timely basis all reports and any definitive proxy or
     information statements required to be filed by the Company with the
     Commission subsequent to the date of the Prospectus and prior to the
     termination of the offering of the Shares by the Underwriters.

          (ii)  The Company will advise the Representatives and the Selling
     Stockholders promptly (A) when the Registration Statement or any post-
     effective amendment thereto shall have become effective, (B) of receipt of
     any comments from the Commission, (C) of any request of the Commission for
     amendment of the Registration Statement or for supplement to the Prospectus
     or for any additional information, and (D) of the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or the use of the Prospectus or of the institution
     of any proceedings for that purpose. The Company will use its best efforts
     to prevent the issuance of any such stop order preventing or suspending the
     use of the Prospectus and to obtain as soon as possible the lifting
     thereof, if issued.

          (iii)  The Company will cooperate with the Representatives in
     endeavoring to qualify the Shares for sale under the securities laws of
     such jurisdictions as the Representatives may reasonably have designated in
     writing and will make such applications, file such documents, and furnish
     such information as may be reasonably required for that purpose, provided
     the Company shall not be required to qualify as a foreign corporation or to
     file a general consent to service of process in any jurisdiction where it
     is not now so qualified or required to file such a consent. The Company
     will, from time to time, prepare and file such statements, reports, and
     other documents, as are or may be required to continue such qualifications
     in effect for so long a period as the Representatives may reasonably
     request for distribution of the Shares.

                                       11
<PAGE>
 
          (iv)  The Company will deliver to, or upon the order of, the
     Representatives, from time to time, as many copies of any Preliminary
     Prospectus as the Representatives may reasonably request. The Company will
     deliver to, or upon the order of, the Representatives during the period
     when delivery of a Prospectus is required under the Act, as many copies of
     the Prospectus in final form, or as thereafter amended or supplemented, as
     the Representatives may reasonably request. The Company will deliver to the
     Representatives at or before the Closing Date, four signed copies of the
     Registration Statement and all amendments thereto including all exhibits
     filed therewith, and will deliver to the Representatives such number of
     copies of the Registration Statement (including such number of copies of
     the exhibits filed therewith that may reasonably be requested), including
     documents incorporated by reference therein, and of all amendments thereto,
     as the Representatives may reasonably request.

          (v)  The Company will comply with the Act and the Rules and
     Regulations, and the Securities Exchange Act of 1934 (the "Exchange Act"),
     and the rules and regulations of the Commission thereunder, so as to permit
     the completion of the distribution of the Shares as contemplated in this
     Agreement and the Prospectus. If during the period in which a prospectus is
     required by law to be delivered by an Underwriter or dealer, any event
     shall occur as a result of which, in the judgment of the Company or in the
     reasonable opinion of the Underwriters, it becomes necessary to amend or
     supplement the Prospectus in order to make the statements therein, in the
     light of the circumstances existing at the time the Prospectus is delivered
     to a purchaser, not misleading, or, if it is necessary at any time to amend
     or supplement the Prospectus to comply with any law, the Company promptly
     will either (i) prepare and file with the Commission an appropriate
     amendment to the Registration Statement or supplement to the Prospectus or
     (ii) prepare and file with the Commission an appropriate filing under the
     Securities Exchange Act of 1934 which shall be incorporated by reference in
     the Prospectus so that the Prospectus as so amended or supplemented will
     not, in the light of the circumstances when it is so delivered, be
     misleading, or so that the Prospectus will comply with the law.

          (vi)  The Company will make generally available to its security
     holders, as soon as it is practicable to do so, but in any event not later
     than 15 months after the effective date of the Registration Statement, an
     earning statement (which need not be audited) in reasonable detail,
     covering a period of at least 12 consecutive months beginning after the
     effective date of the Registration Statement, which earning statement shall
     satisfy the requirements of Section 11(a) of the Act and Rule 158 of the
     Rules and Regulations and will advise you in writing when such statement
     has been so made available.

          (vii)  Prior to the Closing Date, the Company will furnish to the
     Underwriters, as soon as they have been prepared by or are available to the
     Company, a copy of any unaudited interim financial statements of the
     Company for any period subsequent to the period covered by the most recent
     financial statements appearing in the Registration Statement and the
     Prospectus. The Company will, for a period of five years from the Closing
     Date, deliver to the Representatives copies of annual reports and copies of
     all other documents, reports and information furnished by the Company to
     its stockholders 

                                       12
<PAGE>
 
     or filed with any securities exchange pursuant to the requirements of such
     exchange or with the Commission pursuant to the Act or the Securities
     Exchange Act of 1934, as amended. The Company will deliver to the
     Representatives similar reports with respect to significant subsidiaries,
     as that term is defined in the Rules and Regulations, which are not
     consolidated in the Company's financial statements.

          (viii)  No offering, sale, short sale or other disposition of any
     shares of Common Stock of the Company (other than shares issuable upon the
     exercise of currently outstanding options and warrants) or other securities
     convertible into or exchangeable or exerciseable for shares of Common Stock
     or derivative of Common Stock (or agreement for such) will be made for a
     period of 90 days after the date of this Agreement, directly or indirectly,
     by the Company otherwise than hereunder or with the prior written consent
     of BT Alex. Brown Incorporated.

          (ix)  The Company will use its best efforts to list, subject to notice
     of issuance, the Shares on the American Stock Exchange.

          (x)  The Company has caused each of its officers and directors, Chase
     Venture Capital Associates, L.P. ("CVCA") and Banque Paribas to furnish to
     you, on or prior to the date of this agreement, a letter or letters, in
     form and substance satisfactory to the Underwriters, pursuant to which each
     of its officers and directors and CVCA shall agree not to offer, sell, sell
     short or otherwise dispose of any shares of Common Stock of the Company or
     other capital stock of the Company, or any other securities convertible,
     exchangeable or exerciseable for Common Shares or derivative of Common
     Shares owned by such person or request the registration for the offer or
     sale of any of the foregoing (or as to which such person has the right to
     direct the disposition of), and pursuant to which Banque Paribas shall
     agree not to offer, sell, sell short or otherwise dispose of any shares of
     Common Stock of the Company underlying warrants held by Banque Paribas, for
     a period of 90 days after the date of this Agreement, directly or
     indirectly, except with the prior written consent of BT Alex. Brown
     Incorporated ("Lockup Agreements").

          (xi)  The Company shall apply the net proceeds of its sale of the
     Shares as set forth in the Prospectus and shall file such reports with the
     Commission with respect to the sale of the Shares and the application of
     the proceeds therefrom as may be required in accordance with Rule 463 under
     the Act.

          (xii)  The Company shall not invest, or otherwise use the proceeds
     received by the Company from its sale of the Shares in such a manner as
     would require the Company or any of the Subsidiaries to register as an
     investment company under the Investment Company Act of 1940, as amended
     (the "1940 Act").

          (xiii)  The Company will maintain a transfer agent and, if necessary
     under the jurisdiction of incorporation of the Company, a registrar for the
     Common Stock.

                                       13
<PAGE>
 
          (xiv)  The Company will not take, directly or indirectly, any action
     designed to cause or result in, or that has constituted or might reasonably
     be expected to constitute, the stabilization or manipulation of the price
     of any securities of the Company.

          (xv)  The Company shall adopt and implement a compliance plan that
     will include all material elements of an effective program to prevent and
     detect violations of law as identified in Commentary 3(k) to Section 8A1.2
     of the federal Sentencing Guidelines.

          (b)  Each of the Selling Stockholders covenants and agrees with the
     several Underwriters that:

               (i)  No offering, sale, short sale or other disposition of any
          shares of Common Stock of the Company or other capital stock of the
          Company or other securities convertible, exchangeable or exercisable
          for Common Stock or derivative of Common Stock owned by the Selling
          Stockholder or request the registration for the offer or sale of any
          of the foregoing (or as to which the Selling Stockholder has the right
          to direct the disposition of) will be made for a period of 90 days
          after the date of this Agreement, directly or indirectly, by such
          Selling Stockholder otherwise than hereunder or with the prior written
          consent of BT Alex. Brown Incorporated.

               (ii)  In order to document the Underwriters' compliance with the
          reporting and withholding provisions of the Tax Equity and Fiscal
          Responsibility Act of 1982 and the Interest and Dividend Tax
          Compliance Act of 1983 with respect to the transactions herein
          contemplated, each of the Selling Stockholders agrees to deliver to
          you prior to or at the Closing Date a properly completed and executed
          United States Treasury Department Form W-9 (or other applicable form
          or statement specified by Treasury Department regulations in lieu
          thereof).

               (iii)  Such Selling Stockholder will not take, directly or
          indirectly, any action designed to cause or result in, or that has
          constituted or might reasonably be expected to constitute, the
          stabilization or manipulation of the price of any securities of the
          Company.

     5.   COSTS AND EXPENSES.
          ------------------ 

          The Company will pay all costs, expenses and fees incident to the
     performance of the obligations of the Sellers under this Agreement,
     including, without limiting the generality of the foregoing, the following:
     accounting fees of the Company; the fees and disbursements of counsel for
     the Company and the Selling Stockholders; the cost of printing and
     delivering to, or as requested by, the Underwriters copies of the
     Registration Statement, Preliminary Prospectuses, the Prospectus, this
     Agreement, the Underwriters' Selling Memorandum, the Underwriters'
     Invitation Letter, the Listing Application, the Blue Sky Survey and any
     supplements or amendments thereto; the filing fees of the Commission; the
     filing fees and expenses (including reasonable legal fees and

                                       14
<PAGE>
 
     disbursements) incident to securing any required review by the National
     Association of Securities Dealers, Inc. (the "NASD") of the terms of the
     sale of the Shares; the Listing Fee of the American Stock Exchange; and the
     expenses, including the reasonable fees and disbursements of counsel for
     the Underwriters, incurred in connection with the qualification of the
     Shares under State securities or Blue Sky laws. Any transfer taxes imposed
     on the sale of the shares to the several Underwriters will be paid by the
     Sellers pro rata. The Company agrees to pay all costs and expenses of the
     Underwriters including the fees and disbursements of counsel for the
     Underwriters incident to the offer and sale of directed shares of the
     Common Stock by the Underwriters to employees and persons having business

     however, be required to pay for any of the Underwriters expenses (other
     than, in the case of the Company only, those related to qualification under
     NASD regulation and State securities or Blue Sky laws) except that, if this
     Agreement shall not be consummated because the conditions in Section 6
     hereof are not satisfied, or because this Agreement is terminated by the
     Representatives pursuant to Section 11 hereof, or by reason of any failure,
     refusal or inability on the part of the Company or the Selling Stockholders
     to perform any undertaking or satisfy any condition of this Agreement or to
     comply with any of the terms hereof on their part to be performed, unless
     such failure to satisfy said condition or to comply with said terms be due
     to the default or omission of any Underwriter, then the Company shall
     reimburse the several Underwriters for reasonable out-of-pocket expenses,
     including fees and disbursements of counsel, reasonably incurred in
     connection with investigating, marketing and proposing to market the Shares
     or in contemplation of performing their obligations hereunder; but the
     Company and the Selling Stockholders shall not in any event be liable to
     any of the several Underwriters for damages on account of loss of
     anticipated profits from the sale by them of the Shares.
     
     6.   CONDITIONS OF OBLIGATIONS OF THE UNDERWRITERS.
          --------------------------------------------- 

          The several obligations of the Underwriters to purchase the Firm
     Shares on the Closing Date and the Option Shares, if any, on the Option
     Closing Date are subject to the accuracy, as of the Closing Date or the
     Option Closing Date, as the case may be, of the representations and
     warranties of the Company and the Selling Stockholders contained herein,
     and to the performance by the Company and the Selling Stockholders of their
     covenants and obligations hereunder and to the following additional
     conditions:

          (a)  The Registration Statement and all post-effective amendments
     thereto shall have become effective and any and all filings required by
     Rule 424 and Rule 430A of the Rules and Regulations shall have been made,
     and any request of the Commission for additional information (to be
     included in the Registration Statement or otherwise) shall have been
     disclosed to the Representatives and complied with to their reasonable
     satisfaction. No stop order suspending the effectiveness of the
     Registration Statement, as amended from time to time, shall have been
     issued and no proceedings for that purpose shall have been taken or, to the
     knowledge of the Company or the Selling Stockholders, shall be contemplated
     by the Commission and no injunction, restraining order, or order of 

                                       15
<PAGE>
 
     any nature by a Federal or state court of competent jurisdiction shall have
     been issued as of the Closing Date which would prevent the issuance of the
     Shares.

          (b)  The Representatives shall have received on the Closing Date or
     the Option Closing Date, as the case may be, the opinion of Freedman, Levy,
     Kroll & Simonds, counsel for the Company and the Selling Stockholders,
     dated the Closing Date or the Option Closing Date, as the case may be,
     addressed to the Underwriters (and stating that it may be relied upon by
     counsel to the Underwriters) to the effect that:

               (i)  The Company has been duly organized and is validly existing

          the jurisdiction of its incorporation, with corporate power and
          authority to own or lease its properties and conduct its business as
          described in the Registration Statement; 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, or in which the failure to qualify would have a
          materially adverse effect upon the business of the Company and the
          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; and, to the best of such counsel's
          knowledge, the outstanding shares of capital stock of each of the
          Subsidiaries is owned free and clear of all liens, encumbrances and
          equities and claims, 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.

               (ii)  The Company has authorized and outstanding capital stock as
          set forth under the caption "Capitalization" in the Prospectus; the
          authorized shares of the Company's Common Stock have been duly
          authorized; the outstanding shares of the Company's Common Stock,
          including the shares to be sold by the Selling Stockholders, have been

          assessable; all of the Shares conform to the description thereof
          contained in the Prospectus; the certificates for the Shares, assuming
          they are in the form filed with the Commission, are in due and proper
          form; the shares of Common Stock, including the Option Shares, if any,
          to be sold by the Company pursuant to this Agreement have been duly
          authorized and will be validly issued, fully paid and non-assessable
          when issued and paid for as contemplated by this Agreement; and no
          preemptive rights of stockholders exist with respect to any of the
          Shares or the issue or sale thereof.

               (iii)  Except as described in or contemplated by the Prospectus,
          to the knowledge of such counsel, there are no outstanding securities
          of the Company 

                                       16

          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 into or evidencing
          the right to purchase or subscribe for any shares of such stock; and
          except as described in the Prospectus, to the knowledge of such
          counsel, no holder of any securities of the Company or any other
          person has the right, contractual or otherwise, which has not been
          satisfied or effectively waived, to cause the Company to sell or
          otherwise issue to them, or to permit them to underwrite the sale of,
          any of the Shares or the right to have any Common Shares or other
          securities of the Company included in the Registration Statement or
          the right, as a result of the filing of the Registration Statement, to
          require registration under the Act of any shares of Common Stock or
          other securities of the Company.

               (iv)  The Registration Statement has become effective under the
          Act and, to the best of the knowledge of such counsel, no stop order
          proceedings with respect thereto have been instituted or are pending
          or threatened under the Act.

               (v)  The Registration Statement, the Prospectus and each
          amendment or supplement thereto and documents incorporated by
          reference therein comply as to form in all material respects with the
          requirements of the Act or the Securities Exchange Act of 1934, as
          applicable and the applicable rules and regulations thereunder (except
          that such counsel need express no opinion as to the financial
          statements and related schedules or material incorporated by reference
          therein). Form S-3 is available for use by the Company.

               (vi)  The statements under the caption "Risk Factors -- Shares
          Eligible for Future Sale" in the Prospectus, insofar as such
          statements constitute a summary of documents referred to therein or
          matters of law, fairly summarize in all material respects the
          information called for with respect to such documents and matters.

               (vii)  Such counsel does not know of any contracts or documents
          required to be filed as exhibits to or incorporated by reference in
          the Registration Statement or described in the Registration Statement
          or the Prospectus which are no so filed, incorporated by reference 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.

               (viii)  Such counsel knows of no material legal or governmental
          proceedings pending or threatened against the Company or any of the
          Subsidiaries except as set forth in the Prospectus.

               (ix)  The execution and delivery of this Agreement and the
          consummation of the transactions herein 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 

                                       17
<PAGE>
 
          Charter or By-Laws of the Company, or any agreement or instrument
          known to such counsel to which the Company or any of the Subsidiaries
          is a party or by which the Company or any of the Subsidiaries may be
          bound.

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

               (xi)  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 this Agreement and the consummation of the
          transactions herein contemplated (other than as may be required by the
          NASD or as required by State securities and Blue Sky laws as to which
          such counsel need express no opinion) except such as have been
          obtained or made, specifying the same.

               (xii)  The Company is not, and will not become, as a result of
          the consummation of the transactions contemplated by this Agreement,
          and application of the net proceeds therefrom as described in the
          Prospectus, required to register as an investment company under the
          1940 Act.

               (xiii)  This Agreement has been duly authorized, executed and
          delivered on behalf of the Selling Stockholders.

               (xiv)  Each Selling Stockholder has full legal right, power and
          authority, and any approval required by law (other than as required by
          the National Association of Securities Dealers, Inc., or by State
          securities and Blue Sky laws as to which such counsel need express no
          opinion), to sell, assign, transfer and deliver the portion of the
          Shares to be sold by such Selling Stockholder.

               (xv)  The Custody Agreement and the Power of Attorney executed
          and delivered by each Selling Stockholder is valid and binding.

               (xvi)  The Underwriters (assuming that they are bona fide
          purchasers within the meaning of the Uniform Commercial Code) have
          acquired good and valid title to the Shares being sold by each Selling
          Stockholder on the Closing Date, free and clear of all liens,
          encumbrances, equities and claims.

          In rendering such opinion Freedman, Levy, Kroll & Simonds may rely as
     to matters governed by the laws of States other than Delaware or Maryland
     or the District of Columbia or Federal laws on local counsel in such
     jurisdictions and, as to matters set forth in subparagraphs (xiii), (xiv)
     and (xv), on opinions of other counsel representing the respective Selling
     Stockholder, provided that in each case Freedman, Levy, Kroll & Simonds
     shall state that they believe that they and the Underwriters are justified
     in relying on such other counsel. In addition to the matters set forth
     above, such opinion shall also include a statement to the effect that
     nothing has come to the attention of such 

                                       18
<PAGE>
 
     counsel which leads them to believe that (i) the Registration Statement, at
     the time it became effective under the Act (but after giving effect to any
     modifications incorporated therein pursuant to Rule 430A under the Act) and
     as of the Closing Date or the Option Closing Date, as the case may be,
     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, and (ii) the Prospectus, or any
     supplement thereto, on the date it was filed pursuant to the Rules and
     Regulations and as of the Closing Date or the Option Closing Date, as the
     case may be, contained an untrue statement of a material fact or omitted to
     state a material fact necessary in order to make the statements, in the
     light of the circumstances under which they are made, not misleading
     (except that such counsel need express no view as to financial statements
     and schedules and other financial and statistical information included or
     incorporated therein). With respect to such statement, Freedman, Levy,
     Kroll & Simonds may state that their belief is based upon the procedures
     set forth therein, but is without independent check and verification.

          (c)  The Representatives shall have received from Hogan & Hartson
     L.L.P., counsel for the Underwriters, an opinion dated the Closing Date or
     the Option Closing Date, as the case may be, substantially to the effect
     specified in subparagraphs (ii), (iii), (iv) and (x) of Paragraph (b) of
     this Section 6, and that the Company is a duly organized and validly
     existing corporation under the laws of the State of Delaware. In rendering
     such opinion Hogan & Hartson L.L.P. may rely as to all matters governed
     other than by the laws of the States of Delaware or Maryland or the
     District of Columbia or Federal laws on the opinion of counsel referred to
     in Paragraph (b) of this Section 6. In addition to the matters set forth
     above, such opinion shall also include a statement to the effect that
     nothing has come to the attention of such counsel which leads them to
     believe that (i) the Registration Statement, or any amendment thereto, as
     of the time it became effective under the Act (but after giving effect to
     any modifications incorporated therein pursuant to Rule 430A under the Act)
     as of the Closing Date or the Option Closing Date, as the case may be,
     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, and (ii) the Prospectus, or any
     supplement thereto, on the date it was filed pursuant to the Rules and
     Regulations and as of the Closing Date or the Option Closing Date, as the
     case may be, contained an untrue statement of a material fact or omitted to
     state a material fact, necessary in order to make the statements, in the
     light of the circumstances under which they are made, not misleading
     (except that such counsel need express no view as to financial statements
     and schedules and other financial and statistical information included or
     incorporated therein). With respect to such statement, Hogan & Hartson
     L.L.P. may state that their belief is based upon the procedures set forth
     therein, but is without independent check and verification.

          (d)  The Representatives shall have received, on each of the dates
     hereof, the Closing Date and the Option Closing Date, as the case may be, a
     letter dated the date hereof, the Closing Date or the Option Closing Date,
     as the case may be, in form and substance satisfactory to you, of Coopers &
     Lybrand L.L.P. confirming that they are independent public accountants
     within the meaning of the Act and the applicable 

                                       19
<PAGE>
 
     published Rules and Regulations thereunder and stating that in their
     opinion the financial statements and schedules examined by them and
     included in the Registration Statement comply in form in all material
     respects with the applicable accounting requirements of the Act and the
     related published Rules and Regulations; and containing such other
     statements and information as is ordinarily included in accountants'
     "comfort letters" to Underwriters with respect to the financial statements
     and certain financial and statistical information contained in the
     Registration Statement and Prospectus.

          (e)  The Representatives shall have received on the Closing Date or
     the Option Closing Date, as the case may be, a certificate or certificates
     of the Chief Executive Officer and the Chief Financial Officer of the
     Company to the effect that, as of the Closing Date or the Option Closing
     Date, as the case may be, each of them severally represents as follows:

               (i)  The Registration Statement has become effective under the
          Act and no stop order suspending the effectiveness of the Registration
          Statement has been issued, and no proceedings for such purpose have
          been taken or are, to his knowledge, contemplated by the Commission;

               (ii)  The representations and warranties of the Company contained
          in Section 1 hereof are true and correct as of the Closing Date or the
          Option Closing Date, as the case may be;

               (iii)  All filings required to have been made pursuant to Rules
          424 or 430A under the Act have been made;

               (iv)  He has carefully examined the Registration Statement and
          the Prospectus and, in his opinion, as of the effective date of the
          Registration Statement, the statements contained in the Registration
          Statement were true and correct, and such Registration Statement and
          Prospectus did not omit to state a material fact required to be stated
          therein or necessary in order to make the statements therein not
          misleading, and since the effective date of the Registration
          Statement, no event has occurred which should have been set forth in a
          supplement to or an amendment of the Prospectus which has not been so
          set forth in such supplement or amendment; and

               (v)  Since the respective dates as of which information is given
          in the Registration Statement and Prospectus, there has not been any
          material adverse change or any development involving a prospective
          material adverse change in or affecting the condition, financial or
          otherwise, of the Company and its Subsidiaries taken as a whole or the
          earnings, business, management, properties, assets, rights,
          operations, condition (financial or otherwise) or prospects of the
          Company and the Subsidiaries taken as a whole, whether or not arising
          in the ordinary course of business.

                                       20

          (f)  The Company and the Selling Stockholders shall have furnished to
     the Representatives such further certificates and documents confirming the
     representations and warranties, covenants and conditions contained herein
     and related matters as the Representatives may reasonably have requested.

          (g)  The Firm Shares and Option Shares, if any, have been approved for
     listing upon notice of issuance on the American Stock Exchange.

          (h)  The Lockup Agreements described in Section 4(a)(x) are in full
     force and effect.

          The opinions and certificates mentioned in this Agreement shall be
     deemed to be in compliance with the provisions hereof only if they are in
     all material respects satisfactory to the Representatives and to Hogan &
     Hartson L.L.P., counsel for the Underwriters.

          If any of the conditions hereinabove provided for in this Section 6
     shall not have been fulfilled when and as required by this Agreement to be
     fulfilled, the obligations of the Underwriters hereunder may be terminated
     by the Representatives by notifying the Company and the Selling
     Stockholders of such termination in writing or by telegram at or prior to
     the Closing Date or the Option Closing Date, as the case may be.

          In such event, the Company, the Selling Stockholders and the
     Underwriters shall not be under any obligation to each other (except to the
     extent provided in Sections 5 and 8 hereof).

     7.   CONDITIONS OF THE OBLIGATIONS OF THE SELLERS.
          -------------------------------------------- 

          The obligations of the Sellers to sell and deliver the portion of the
     Shares required to be delivered as and when specified in this Agreement are
     subject to the conditions that at the Closing Date or the Option Closing
     Date, as the case may be, no stop order suspending the effectiveness of the
     Registration Statement shall have been issued and in effect or proceedings
     therefor initiated or threatened.

     8.   INDEMNIFICATION.
          --------------- 

          (a)  The Company agrees to indemnify and hold harmless, and Ivan R.
     Sabel and Richard A. Stein (the "Management Stockholders") agree to
     indemnify and hold harmless, each Underwriter and each person, if any, who
     controls any Underwriter within the meaning of the Act, against any losses,
     claims, damages or liabilities to which such Underwriter or any such
     controlling person may become subject under the Act or otherwise, insofar
     as such losses, claims, damages or liabilities (or actions or proceedings
     in respect thereof) arise out of or are based upon (i) any untrue statement
     or alleged untrue statement of any material fact contained in the
     Registration Statement, any Preliminary Prospectus, the Prospectus or any
     amendment or supplement thereto, (ii) the 

                                       21
<PAGE>
 
     omission or alleged omission to state therein a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, in the light of the circumstances under which they were made,
     or (iii) any oral untrue statement or alleged untrue statement of any
     material fact referred to in clause (i) or (ii) above by any Underwriter in
     connection with the offering contemplated hereby (provided, that the
     Company and the Management Stockholders shall not be liable under this
     clause (iii) to the extent that it is determined in a final judgment by a
     court of competent jurisdiction that such loss, claim, damage, liability or
     action resulted directly from any such acts or failures to act undertaken
     or omitted to be taken by such Underwriter through its gross negligence or
     willful misconduct); and will reimburse each Underwriter and each such
     controlling person upon demand for any legal or other expenses reasonably
     incurred by such Underwriter or such controlling person in connection with
     investigating or defending any such loss, claim, damage or liability,
     action or proceeding or in responding to a subpoena or governmental inquiry
     related to the offering of the Shares, whether or not such Underwriter or
     controlling person is a party to any action or proceeding; provided,
     however, that the Company and the Management Stockholders will not be
     liable in any such case to the extent that any such loss, claim, damage or
     liability arises out of or is based upon an untrue statement or alleged
     untrue statement, or omission or alleged omission made in the Registration
     Statement, any Preliminary Prospectus, the Prospectus, or such amendment or
     supplement, in reliance upon and in conformity with written information
     furnished to the Company by or through the Representatives specifically for
     use in the preparation thereof. Notwithstanding the foregoing, the
     obligations of the Management Stockholders to indemnify pursuant to this
     Section 8 shall not, in the case of each Management Stockholder, exceed the
     amount of offering proceeds received by such Management Stockholder as a
     Selling Stockholder. This indemnity agreement will be in addition to any
     liability which the Company or the Management Stockholders may otherwise
     have.

          (b)  CVCA agrees to indemnify and hold harmless each Underwriter and
     each person, if any, who controls any Underwriter within the meaning of the
     Act to the same extent as the foregoing indemnity of the Company to the
     Underwriters, but only with reference to information relating to CVCA
     included or incorporated by reference in the Registration Statement, any
     Preliminary Prospectus, the Prospectus or any amendment of supplement
     thereto.

          (c)  Each Underwriter agrees severally and not jointly to indemnify
     and hold harmless the Company, each of its directors, each of its officers
     who have signed the Registration Statement, the Selling Stockholders and
     each person, if any, who controls the Company or the Selling Stockholders
     within the meaning of the Act, against any losses, claims, damages or
     liabilities to which the Company or any such director, officer, Selling
     Stockholder or controlling person may become subject under the Act or
     otherwise, insofar as such losses, claims, damages or liabilities (or
     actions or proceedings in respect thereof) arise out of or are based upon
     (i) any untrue statement or alleged untrue statement of any material fact
     contained in the Registration Statement, any Preliminary Prospectus, the
     Prospectus or any amendment or supplement thereto, or 

                                       22
<PAGE>
 
     (ii) the omission or the alleged omission to state therein a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading in the light of the circumstances under which they were
     made; and will reimburse any legal or other expenses reasonably incurred by
     the Company or any such director, officer, Selling Stockholder or
     controlling person in connection with investigating or defending any such
     loss, claim, damage, liability, action or proceeding; provided, however,
     that each Underwriter will be liable in each case to the extent, but only
     to the extent, that such untrue statement or alleged untrue statement or
     omission or alleged omission has been made in the Registration Statement,
     any Preliminary Prospectus, the Prospectus or such amendment or supplement,
     in reliance upon and in conformity with written information furnished to
     the Company by or through the Representatives specifically for use in the
     preparation thereof. This indemnity agreement will be in addition to any
     liability which such Underwriter may otherwise have.

          (d)  In case any proceeding (including any governmental investigation)
     shall be instituted involving any person in respect of which indemnity may
     be sought pursuant to this Section 8, such person (the "indemnified party")
     shall promptly notify the person against whom such indemnity may be sought
     (the "indemnifying party") in writing.  No indemnification provided for in
     Section 8(a), (b) or (c) shall be available to any party who shall fail to
     give notice as provided in this Section 8(d) if the party to whom notice
     was not given was unaware of the proceeding to which such notice would have
     related and was materially prejudiced by the failure to give such notice,
     but the failure to give such notice shall not relieve the indemnifying
     party or parties from any liability which it or they may have to the
     indemnified party for contribution or otherwise than on account of the
     provisions of Section 8(a), (b) or (c).  In case any such proceeding shall
     be brought against any indemnified party and it shall notify the
     indemnifying party of the commencement thereof, the indemnifying party
     shall be entitled to participate therein and, to the extent that it shall
     wish, jointly with any other indemnifying party similarly notified, to
     assume the defense thereof, with counsel satisfactory to such indemnified
     party and shall pay as incurred (or within 30 days of presentation) the
     fees and disbursements of such counsel related to such proceeding.  In any
     such proceeding, any indemnified party shall have the right to retain its
     own counsel at its own expense.  Notwithstanding the foregoing, the
     indemnifying party shall pay as incurred the fees and expenses of the
     counsel retained by the indemnified party in the event (i) the indemnifying
     party and the indemnified party shall have mutually agreed to the retention
     of such counsel, (ii) the named parties to any such proceeding (including
     any impleaded parties) include both the indemnifying party and the
     indemnified party and representation of both parties by the same counsel
     would be inappropriate due to actual or potential differing interests
     between them or (iii) the indemnifying party shall have failed to assume
     the defense and employ counsel acceptable to the indemnified party within a
     reasonable period of time after notice of commencement of the action.  It
     is understood that the indemnifying party shall not, in connection with any
     proceeding or related proceedings in the same jurisdiction, be liable for
     the reasonable fees and expenses of more than one separate firm for all
     such indemnified parties.  Such firm shall be designated in writing by you
     in the case of parties indemnified pursuant to Section 8(a) 

                                       23
<PAGE>
 
     and 8(b) and by the Company in the case of parties indemnified pursuant to
     Section 8(c). The indemnifying party shall not be liable for any settlement
     of any proceeding effected without its written consent but if settled with
     such consent or if there be a final judgment for the plaintiff, the
     indemnifying party agrees to indemnify the indemnified party from and
     against any loss or liability by reason of such settlement or judgment. In
     addition, the indemnifying party will not, without the prior written
     consent of the indemnified party, settle or compromise or consent to the
     entry of any judgment in any pending or threatened claim, action or
     proceeding of which indemnification may be sought hereunder (whether or not
     any indemnified party is an actual or potential party to such claim, action
     or proceeding) unless such settlement, compromise or consent includes an
     unconditional release of each indemnified party from all liability arising
     out of such claim, action or proceeding.

          (e)  If the indemnification provided for in this Section 8 is
     unavailable to or insufficient to hold harmless an indemnified party under
     Section 8(a), (b) or (c) above in respect of any losses, claims, damages or
     liabilities (or actions or proceedings in respect thereof) referred to
     therein, then each indemnifying party shall contribute to the amount paid
     or payable by such indemnified party as a result of such losses, claims,
     damages or liabilities (or actions or proceedings in respect thereof) in
     such proportion as is appropriate to reflect the relative benefits received
     by the Sellers and the Underwriters from the offering of the Shares. If,
     however, the allocation provided by the immediately preceding sentence is
     not permitted by applicable law then each indemnifying party shall
     contribute to such amount paid or payable by such indemnified party in such
     proportion as is appropriate to reflect not only such relative benefits but
     also the relative fault of the Company and the Selling Stockholders on the
     one hand and the Underwriters on the other in connection with the
     statements or omissions which resulted in such losses, claims, damages or
     liabilities, (or actions or proceedings in respect thereof), as well as any
     other relevant equitable considerations. The relative benefits received by
     the Company, the Selling Stockholders and the Underwriters shall be deemed
     to be in the same respective proportions as the total net proceeds from the
     offering (before deducting expenses) received by each of the Company and
     the Selling Stockholders and the total underwriting discounts and
     commissions received by the Underwriters, in each case as set forth in the
     table on the cover page of the Prospectus, bear to the aggregate public
     offering price of the Shares. The relative fault 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 Company and the
     Selling Stockholders on the one hand or the Underwriters on the other and
     the parties' relative 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 contributions pursuant to this
     Section 8(e) 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 8(e). The amount paid or
     payable by an 

                                       24
<PAGE>
 
     indemnified party as a result of the losses, claims, damages or liabilities
     (or actions or proceedings in respect thereof) referred to above in this
     Section 8(e) shall be deemed to include any legal or other expenses
     reasonably incurred by such indemnified party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this subsection (e), (i) no Underwriter shall be required to
     contribute any amount in excess of the underwriting discounts and
     commissions applicable to the Shares purchased by such Underwriter, and
     (ii) no person guilty of fraudulent misrepresentation (within the meaning
     of Section 11(f) of the Act) shall be entitled to contribution from any
     person who was not guilty of such fraudulent misrepresentation. The
     Underwriters' obligations in this Section 8(e) to contribute are several in
     proportion to their respective underwriting obligations and not joint.

          (f)  In any proceeding relating to the Registration Statement, any
     Preliminary Prospectus, the Prospectus or any supplement or amendment
     thereto, each party against whom contribution may be sought under this
     Section 8 hereby consents to the jurisdiction of any court having
     jurisdiction over any other contributing party, agrees that process issuing
     from such court may be served upon him or it by any other contributing
     party and consents to the service of such process and agrees that any other
     contributing party may join him or it as an additional defendant in any
     such proceeding in which such other contributing party is a party.

          (g)  Any losses, claims, damages, liabilities or expenses for which an
     indemnified party is entitled to indemnification or contribution under this
     Section 8 shall be paid by the indemnifying party to the indemnified party
     as such losses, claims, damages, liabilities or expenses are incurred. The
     indemnity and contribution agreements contained in this Section 8 and the
     representations and warranties of the Company set forth in this Agreement
     shall remain operative and in full force and effect, regardless of (i) any
     investigation made by or on behalf of any Underwriter or any person
     controlling any Underwriter, the Company, its directors or officers or any
     persons controlling the Company, (ii) acceptance of any Shares and payment
     therefor hereunder, and (iii) any termination of this Agreement. A
     successor to any Underwriter, or to the Company, its directors or officers,
     or any person controlling the Company, shall be entitled to the benefits of
     the indemnity, contribution and reimbursement agreements contained in this
     Section 8.

          (h)  Notwithstanding anything to the contrary contained in this
     Agreement, the provisions of the Registration Agreement dated as of May 15,
     1989 shall govern rights to indemnification and contribution as between the
     Company and the Selling Stockholders, provided that the provisions of such
     Registration Agreement shall have no impact whatsoever on the rights of the
     Underwriters to indemnification under this Agreement.

     9.   DEFAULT BY UNDERWRITERS.
          ----------------------- 

          If on the Closing Date or the Option Closing Date, as the case may be,
     any Underwriter shall fail to purchase and pay for the portion of the
     Shares which such 

                                       25
<PAGE>
 
     Underwriter has agreed to purchase and pay for on such date (otherwise than
     by reason of any default on the part of the Company or a Selling
     Stockholder), you, as Representatives of the Underwriters, shall use your
     reasonable efforts to procure within 36 hours thereafter one or more of the
     other Underwriters, or any others, to purchase from the Company and the
     Selling Stockholders such amounts as may be agreed upon and upon the terms
     set forth herein, the Firm Shares or Option Shares, as the case may be,
     which the defaulting Underwriter or Underwriters failed to purchase. If
     during such 36 hours you, as such Representatives, shall not have procured
     such other Underwriters, or any others, to purchase the Firm Shares or
     Option Shares, as the case may be, agreed to be purchased by the defaulting
     Underwriter or Underwriters, then (a) if the aggregate number of shares
     with respect to which such default shall occur does not exceed 10% of the
     Firm Shares or Option Shares, as the case may be, covered hereby, the other
     Underwriters shall be obligated, severally, in proportion to the respective
     numbers of Firm Shares or Option Shares, as the case may be, which they are
     obligated to purchase hereunder, to purchase the Firm Shares or Option
     Shares, as the case may be, which such defaulting Underwriter or
     Underwriters failed to purchase, or (b) if the aggregate number of shares
     of Firm Shares or Option Shares, as the case may be, with respect to which
     such default shall occur exceeds 10% of the Firm Shares or Option Shares,
     as the case may be, covered hereby, the Company and the Selling
     Stockholders or you as the Representatives of the Underwriters will have
     the right, by written notice given within the next 36-hour period to the
     parties to this Agreement, to terminate this Agreement without liability on
     the part of the non-defaulting Underwriters or of the Company or of the
     Selling Stockholders except to the extent provided in Section 8 hereof. In
     the event of a default by any Underwriter or Underwriters, as set forth in
     this Section 9, the Closing Date or Option Closing Date, as the case may
     be, may be postponed for such period, not exceeding seven days, as you, as
     Representatives, may determine in order that the required changes in the
     Registration Statement or in the Prospectus or in any other documents or
     arrangements may be effected. The term "Underwriter" includes any person
     substituted for a defaulting Underwriter. Any action taken under this
     Section 9 shall not relieve any defaulting Underwriter from liability in
     respect of any default of such Underwriter under this Agreement.

    Re: Hanger Orthopedic Group, Inc. Registration Statement on Form S-3
 
Gentlemen:
 
  We are counsel to Hanger Orthopedic Group, Inc. (the "Company") and have
represented the Company in connection with the Registration Statement on Form
S-3 being filed by it today with the Commission (together with all exhibits
thereto, the "Registration Statement"). The Registration Statement relates to
an underwritten public offering of up to 3,795,000 shares of the Company's
common stock, par value of $.01 per share, (the "Shares") to be made through a
group of underwriters represented by BT Alex. Brown Incorporated, NationsBanc
Montgomery Securities LLC and Legg Mason Wood Walker, Incorporated. Such
amount includes 2,400,000 Shares being offered by the Company, 900,000 Shares
being offered by certain shareholders of the Company and 495,000 Shares
underlying an over-allotment option to be granted to the underwriters. A form
of underwriting agreement is filed as Exhibit 1 to the Registration Statement
(the "Underwriting Agreement").
 
  This opinion is being delivered to the Commission as Exhibit 5 to the
Registration Statement.
 
  We have examined (1) the Articles of Incorporation, and all amendments
thereto, certified by the Secretary of State of the State of Delaware, (2) the
By-Laws of the Company, certified by the Secretary of the Company as being
those currently in effect, (3) the Registration Statement, and (4) such other
corporate records, certificates, documents and other instruments as in our
opinion are necessary or appropriate in connection with expressing the
opinions set forth below.
 
  Based upon the foregoing, it is our opinion that:
 
  1. The Company is a corporation duly organized and validly existing under
     the laws of the State of Delaware.
 
  2. When the Shares shall have been paid for and issued in accordance with
     the terms of the Underwriting Agreement and as provided in the
     Registration Statement, the Shares thus sold will be legally issued,
     fully paid and non-assessable.
 
  This firm hereby consents to the reference to it under the heading "Legal
Matters" appearing in the Prospectus which is part of the Registration
Statement.
 
                                          Sincerely,
 
                                          Freedman, Levy, Kroll & Simonds

                      CONSENT OF INDEPENDENT ACCOUNTANTS
 
  We consent to the inclusion in and incorporation by reference in this
Registration Statement on Form S-3 of our report, dated March 13, 1998, on our
audits of the consolidated financial statements and financial statement
schedule of Hanger Orthopedic Group, Inc. as of December 31, 1996 and 1997,
and for the years ended December 31, 1995, 1996 and 1997, which report is both
included and incorporated by reference in this Registration Statement. We also
consent to the reference to our firm under the caption "Experts."
