P II, Inc.
 
                                  THE COMPANY
 
    UtiliMed is the nation's leading manager of diagnostic imaging services,
providing a comprehensive approach to managing cost, quality and utilization for
payors with large memberships. The Company's products aim to manage the delivery
of quality necessary diagnostic imaging services by qualified physicians to
patients on a cost effective basis. UtiliMed's products manage costs by
decreasing the volume and increasing the quality of imaging services. Quality
improvement can decrease costs through fewer repeat or extra exams necessitated
by poor quality initial exams. At March 31, 1996, the Company managed diagnostic
imaging services for 16 clients representing over 2.5 million lives in 13
states. In addition, the Company signed a new RMP contract in March 1996
covering 220,000 lives which will be implemented in June 1996.
 
    Founded in December 1989, the Company has achieved rapid growth, with
revenues growing from approximately $2.6 million in 1991 to $96.4 million in
1995 and covered lives, increasing from 102,000 at December 31, 1991 to 2.5
million at March 31, 1996. The Company believes that an opportunity exists for
payors to reduce costs while maintaining quality through more effective
management of these services. As the leading comprehensive provider of
diagnostic imaging management services, the Company believes that it is well
positioned to take advantage of the relatively unpenetrated market for
outsourced management of diagnostic imaging services.
 
    The Company offers its clients a capitated product and a fee-based product,
each of which is designed to reduce excess or improper utilization and improve
the quality of service. The core program elements of the Company's two products
include diagnostic imaging assessment and privileging, diagnostic imaging
pre-certification processes, clinical- and claims-based retrospective
utilization database tools and structured physician education. In its Capitated
Diagnostic Imaging Program ("CDIP"), the Company establishes and maintains
networks of diagnostic imaging providers which meet the Company's assessment
requirements and agree to receive payment from the Company based on appropriate
utilization levels and financial incentives. The Company receives a per member
per month ("pmpm") fee, consisting of compensation for the assumption of
responsibility for medical costs and claims processing, and a fee for the
provision of network management services. In its recently introduced Resource
Management Program ("RMP"), the Company provides network management services in
return for a fee from participating clients. RMP clients are responsible for
establishing and maintaining networks of physicians and retain risk for medical
costs payable to physician providers. The RMP fee does not include payment for
medical costs since RMP does not alter the payment relationship between UtiliMed
clients and providing physicians. The Company maintains a database of claims
data, clinical reports, and assessment information which is an important tool
for network and utilization management. At March 31, 1996, the database
contained claims data for over eight million lives, assessment data for over
10,000 imaging sites and over one million clinical reports. The number of
monthly clinical reports added to the database has grown from approximately
35,000 in March 1995 to approximately 54,000 in March 1996. The database enables
the Company to develop protocols, produce outcomes and benchmarking analyses
(both provider-specific and diagnosis-specific) and to create educational
programs for physicians and other providers. Use of the Company's CDIP product
can result in cost savings of approximately 20% to clients within the first year
and the Company anticipates its RMP product will result in comparable savings to
its clients in the first year.
 
    UtiliMed's objective is to enhance its leading position in diagnostic
imaging managed care services and continue its growth by pursuing a wide range
of significant new opportunities. The Company believes its ability to combine
utilization management, quality management, outcomes management and network
management provides an attractive alternative for payors in managing diagnostic
imaging services. The Company sees opportunities for growth both in establishing
new client relationships and expanding relationships with existing clients--by
extending coverage to additional local health plans of regional and national
payors, such as CIGNA Healthcare, Inc. and United HealthCare, Inc. and by
serving additional membership populations of existing clients, such as members
covered under Medicare and Medicaid programs. The Company will also seek to
market RMP to payors other than HMOs, such as self-funded employers and
indemnity insurers, and to market its products directly to large employer
groups, benefits administrators, and benefits consulting groups.

(1) Represents seven CDIP contracts that were terminated in the third and fourth
    quarters of 1995 (the "Terminated Contracts"). Five of the Terminated
    Contracts were unprofitable contracts terminated by the Company's new
    management team as part of the initiatives being implemented subsequent to
    the 1995 Transaction (as defined herein). These unprofitable contracts were
    entered into without establishment of appropriate provider networks, thereby
    placing the Company at significant financial risk. The other two Terminated
    Contracts were terminated prior to their completion by mutual agreement of
    the Company and the clients. See "Management's Discussion and Analysis of
    Financial Condition and Results of Operations" and "Business--Clients;
    Capitation Contracts and Provider Contracts; RMP Contracts."
 
(2) Net loss per share is computed by dividing net loss by the number of common
    and common equivalent shares outstanding during the periods in accordance
    with the applicable rules of the Securities and Exchange Commission (the
    "Commission"). All stock options and restricted common stock issued have
    been considered as outstanding common stock equivalents for all periods
    presented, even if anti-dilutive, under the treasury stock method (based on
    initial public offering price). Shares of common stock issuable upon
    conversion of the Series A Preferred Stock and Class B Stock are assumed to
    be common share equivalents for all periods presented.
 
(3) The information set forth in Statistical Data reflects only continuing CDIP
    and RMP contracts. Including the Terminated Contracts, the number of
    capitated lives were 102,000, 314,000, 625,000, 1,514,000 and 1,152,000 and
    the number of CDIP contracts were 4, 6, 11, 17 and 12 at December 31, 1991,
    1992, 1993, 1994 and 1995, respectively, and the number of RMP contracts at
    December 31, 1995 was three. See "Management's Discussion and Analysis of
    Financial Condition and Results of Operations."
 
(4) Calculated as cost of services divided by continuing contract revenue
    excluding RMP revenue.
 
(5) Adjusted to reflect the sale by the Company of 2,500,000 shares of Common
    Stock offered hereby and the application of the net proceeds therefrom as
    described under "Use of Proceeds."

                                  RISK FACTORS
 
HEALTH CARE AND REGULATORY ENVIRONMENT
 
    Political, economic and regulatory influences are subjecting the health care
industry in the United States to fundamental change. Although Congress has
failed to pass comprehensive health care reform legislation thus far in 1996,
the Company anticipates that Congress and state legislatures will continue to
review and assess alternative health care delivery and payment systems. The
number of health care proposals considered by state legislatures has increased
in recent years. Potential approaches that have been considered include mandated
basic health care benefits, controls on health care spending through limitations
on the growth of private health insurance premiums and Medicare and Medicaid
spending, the creation of large insurance purchasing groups, the formation of
regional delivery markets and other fundamental changes to the health care
delivery system. Private sector providers and payors have embraced certain
elements of reform, resulting in increased consolidation of medical groups and
competition among managers of medical practice groups as these providers and
payors seek to form alliances in order to provide cost-effective, quality care.
The Company cannot predict whether federal or state health care reform will be
adopted and, if so, what effect any such measures or any private sector reform
may have on its business.
 
    In addition to the possibility of comprehensive health care reform, the
health care industry and physicians' medical practices are highly regulated at
the state and federal levels. The Company believes its operations are in
compliance with applicable law. Nevertheless, because of the rapidly evolving
structure of existing and potential relationships between the Company and
insurers, self-funded employers, health plans and government-sponsored and other
health care cost payors, including health maintenance organizations ("HMOs") and
preferred provider organizations ("PPOs"), many aspects of these relationships
have not been the subject of regulatory interpretation. There can be no
assurance that the review of the Company's business by state or federal courts
or health care and other regulatory authorities will not result in
determinations that could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business--Regulation."
 
    INSURANCE REGULATION
 
    The laws of many states regulate the sharing of risk through capitation. In
many cases, placing providers of diagnostic imaging services at risk outside the
context of a licensed HMO will be deemed to require the obtaining of an
insurance license. In the states in which the Company currently operates,
licensed HMOs can enter into capitation agreements with networks established by
the Company that are comprised of (i) individual providers or (ii) a group of
providers who are linked through certain contractual arrangements ("provider
networks") without the possibility that the associated compensation mechanisms
will require the Company to obtain an insurance license. Due to state insurance
regulations, the Company only offers its CDIP product to HMOs. While the Company
believes that its participation in a capitated provider network does not require
insurance licensure in the states in which it does business, there are a number
of states which may require such licensure which in turn may restrict the
Company's ability to expand its business in such jurisdictions. There can be no
assurance that any state in which the Company does business or may do business
in the future will not impose insurance licensing requirements on all capitated
arrangements and, if it does, there can be no assurance that such insurance
licensing requirements will not have a material adverse effect on the Company's
business, operating results and financial condition. See
"Business--Regulation--State Regulation-- Insurance Regulation."
 
    THIRD PARTY ADMINISTRATOR
 
    Many states regulate third party administrators ("TPAs") or organizations
that provide certain administrative services, such as claims adjustment, claims
processing and premium collection. The administrative services provided by a TPA
include services normally provided by insurers. A TPA that provides services to
group benefit plans and self-insured employers may be subject to state
regulation. The Company believes it is not subject to regulation as a TPA as it
is not engaged in providing services which define a TPA in the states in which
the Company does business. However, there can be no assurance that any state in
which the Company does business or may do business in the future will not seek
to regulate the activities of the Company as a TPA and, if it does, that such
regulations will not
 
                                       7
<PAGE>
have a material adverse effect on the Company's business, operating results and
financial condition. See "Business--Regulation--State Regulation--Third Party
Administrator."
 
    PRIVATE UTILIZATION REVIEW
 
    Some state laws regulate provider network organizations that perform
prospective, concurrent or retrospective reviews of the health care services
provided through the network. Such regulations typically require application and
licensure as a prerequisite to performing utilization review services on
residents of the state and may place restrictions on the types of personnel that
may conduct utilization review. While the Company believes that it is not
currently subject to regulation under utilization review statutes in certain
states, the Company has pending applications for licensure in other states in
which its review procedures fall within the scope of such utilization review
statutes. There can be no assurance that any state in which the Company does
business or may do business in the future will not seek to further regulate the
activities of the Company under such statutes and, if it does, that such
regulation will not have a material adverse effect on the Company's business,
operating results and financial condition. See "Business--Regulation--State
Regulation--Private Utilization Review Agent."
 
    MEDICARE FRAUD AND ABUSE PROVISIONS; THE "STARK LAW"
 
    Federal laws prohibit the offer, payment, solicitation or receipt of any
form of remuneration in return for the referral of Medicare or state health
program patients or patient care opportunities, or in return for the purchase,
lease or order of items or services that are covered by Medicare or state health
programs. Violations of these laws are felonies punishable by fines and
imprisonment for up to five years. The United States Department of Health and
Human Services ("HHS") or state health departments may also impose civil
penalties excluding violators from participation in Medicare or state health
programs. Some state laws include similar prohibitions which apply to private
pay patients as well. In addition, the "Stark Law" prohibits the referral of
Medicare and Medicaid patients by a physician for certain designated health
services, including radiology services, to an entity in which the physician has
an ownership or other financial relationship. Civil monetary penalties may be
imposed for certain prohibited referrals. Some state laws also have similiar
provisions. Although the Company believes that its operations do not violate or
are not subject to these laws, commonly known as the "anti-kickback statutes,"
there can be no assurance that its activities will not be challenged by
regulatory authorities. See "Business--Regulation--Federal Regulation--Medicare
Fraud and Abuse Provisions" and "Business--Regulation--Federal
Regulation--Prohibitions on Certain Referrals--The 'Stark Law.' "
 
    CORPORATE PRACTICE OF MEDICINE AND FEE SPLITTING
 
    The laws of many states prohibit non-physician entities (such as the
Company) from practicing medicine or physicians from splitting fees with
non-physicians. The Company, through its utilization management services, makes
recommendations concerning procedures to be performed by providers throughout
the United States. The Company does not believe that it engages in the practice
of medicine or the delivery of medical services. However, these laws and their
interpretations vary from state to state and are enforced by regulatory
authorities with broad discretion. There can be no assurance that the Company's
existing or future agreements will not be successfully challenged as
constituting the unlicensed practice of medicine or prohibited splitting of fees
with non-physicians. In addition, there can be no assurance that the Company
will not be subject to allegations that the Company engages in the practice of
medicine or the delivery of medical services or subject to claims or litigation
related to the grant or denial of claims for payment of benefits. A successful
challenge with respect to the Company's activities or claims or litigation
related to the grant or denial of claims could have a material adverse effect on
the Company's business, operating results and financial conditions. See
"Business-- Regulation--State Regulation--Corporate Practice of Medicine and Fee
Splitting."
 
    REGULATORY COMPLIANCE
 
    Health care regulations affecting the Company will continue to change and
vary on a state by state basis. The Company believes it will be able to continue
to structure its agreements and operations in accordance with applicable law or,
if necessary, modify its agreements and operations to comply with
 
                                       8
<PAGE>
changing regulations. However, there can be no assurance that regulatory changes
will not have a material adverse effect on the Company's business, operating
results and financial condition. See "Business--Regulation--Regulatory
Compliance."
 
DEPENDENCE ON AND CONTRACT RISKS WITH CLIENTS
 
    The Company's revenues depend entirely on fees and payments received from
the clients with which it contracts. Any material loss of revenue from such
clients could have a material adverse effect on the Company's business,
operating results and financial condition. The Company does not control the
marketing or administration of health care services by its clients or their
compliance with regulatory requirements directly applicable to them. In
addition, fees earned pursuant to contracts with ChoiceCare Health Plans, Inc.,
United HealthCare of Ohio, Inc-Western Region and CIGNA HealthCare of Northern
New Jersey, Inc. accounted for approximately 20.2%, 14.1% and 13.7%,
respectively, of the Company's total revenues in 1995, and approximately 20.0%,
14.6% and 16.0%, respectively, of the Company's total revenues for the first
quarter of 1996. Similarly, although the Company's contracts with clients
affiliated with CIGNA Healthcare, Inc. ("CIGNA") are independently negotiated
and operated, the Company had five such contracts in 1995 that represented, in
the aggregate, 29.3% of total revenues for the year ended December 31, 1995 and,
with the commencement of a sixth contract with a CIGNA affiliated client in
1996, such contracts represented, in the aggregate, 40.7% of the Company's total
revenues for the first quarter of 1996. The Company expects that a majority of
its revenues will continue to be attributable to a limited number of clients.
See "Business--Clients; Capitation Contracts and Provider Contracts; RMP
Contracts."
 
    UtiliMed offers two products to payors: CDIP, a capitated product; and RMP,
a fee-based product. Under CDIP contracts, the Company receives a monthly
payment from its clients comprised of compensation for the assumption of
responsibility for medical costs and claims processing, and a fee for the
provision of network management services. By taking responsibility for the
payment of fees to physicians, the Company must fund any losses that arise in
the event the revenues it receives from clients do not exceed the amounts
payable by the Company to providers. Under RMP contracts, the Company provides
network management services in return for a fee from participating clients. A
portion or all of the Company's RMP fee may have to be refunded if the client
does not realize agreed upon cost savings. Under RMP, the Company makes an
appropriate accrual depending upon whether or not it believes it will meet the
utilization and cost reduction levels in a particular contract. There can be no
assurance that under CDIP contracts revenues from a particular contract will
exceed the Company's payment requirements to providers under such contract, or
that under RMP contracts there will not be negative adjustments in revenues for
future periods. See "Business--Company Products."
 
SHAREHOLDERS' DEFICIT; HISTORY OF OPERATING LOSSES
 
    While the Company had a net deficit in shareholders' equity at March 31,
1996, following the consummation of this offering the Company will have positive
shareholders' equity. See "Capitalization." The Company has incurred operating
losses in each of the last five years. While the Company believes that it is
positioning itself for profitability, there can be no assurance that the Company
will achieve profitability, maintain working capital sufficient to support
operating cash requirements or maintain positive shareholders' equity. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
UNCERTAIN ACCEPTANCE OF NEW PRODUCT
 
    The Company expects to derive an increasing amount of revenue from RMP. To
date, there is insufficient experience with this product to determine its
acceptance in the marketplace. Failure of RMP to achieve market acceptance would
have a material adverse effect on the Company's business, operating results and
financial condition.

NEW MANAGEMENT TEAM; KEY MANAGEMENT
 
    The Company assembled a new executive management team during the second half
of 1995. Although each member of this new management team has experience in the
managed care industry, they have not worked together as a team for a significant
period of time and there can be no assurance that they will continue to perform
or contribute to the business of the Company. The Company is dependent upon its
key management, and the loss of their services, coupled with any inability to
attract and retain qualified replacements could have a material adverse effect
on the Company's business, operating results and financial condition. See
"Management."
 
COMPETITION
 
    The Company faces current and potential competition from a number of diverse
sources and in differing degrees with respect to its two products. There can be
no assurance that other companies will not expand the scope or geographical
range of their services in the future, or that payors will not increasingly
internalize functions similar to those provided by the Company. Many of the
Company's potential competitors are significantly larger and have greater
financial, personnel and marketing resources than those of the Company, and
there can be no assurance that the Company will continue to maintain its
existing performance with respect to either product or be successful in any new
geographical markets it may enter. See "Business--Competition."
 
POSSIBLE LITIGATION AND INSURANCE
 
    The Company does not believe that it engages in the practice of medicine or
the delivery of medical services. There can be no assurance, however, that the
Company will not be subject to claims or litigation related to the provision of
medical services, or that, in the future, certain states or courts will not seek
to assign liability to the Company in connection with its activities that would
subject the Company to the attendant risk of substantial damage awards. In
addition, there can be no assurance that the Company will not be subject to
other litigation that could have a material adverse effect on the Company's
business, operating results and financial condition. The Company maintains
professional liability insurance in the amount of $10 million in the aggregate.
While the Company believes it has adequate professional liability insurance
coverage, there can be no assurance that a future claim or claims will not be
deemed applicable to the Company and successful, or if successful, will not
exceed the limits of available insurance coverage or that such coverage will
continue to be available at acceptable costs and on favorable terms. See
"Business--Insurance."
 
MATERIAL BENEFIT TO INSIDERS; CONTROL BY PRIVATE EQUITY INVESTORS
 
    Of the proceeds to be received by the Company from the sale of the shares of
Common Stock offered hereby, approximately $7 million will be used to repay the
Company's Senior Promissory Notes due March 6, 1997 (the "Senior Notes") issued
to Chase Capital Partners ("CCP") and J.H. Whitney & Co. ("Whitney") and to pay
certain associated deferred fees to CCP and Whitney and approximately $10
million will be used to repay the Company's Senior Subordinated Promissory Notes
due November 3, 2001 (the "Senior Subordinated Notes") issued to CCP and the
Whitney Subordinated Debt Fund, L.P. ("Whitney Debt Fund"). See "Use of
Proceeds" and "Certain Transactions." Two directors of the Board, Jeffrey R.
Jay, M.D. and Peter M. Castleman, are general partners of the Whitney Debt Fund
and Whitney. Two other directors, Mitchell J. Blutt, M.D. and Jonas L. Steinman,
are executive partner and principal, respectively, of CCP. See "Management."
 
    Upon the completion of this offering, CCP, Whitney, Whitney Debt Fund and
the Whitney 1990 Equity Fund, L.P. (collectively, the "Private Equity
Investors") together will beneficially own approximately 47.8% of the
outstanding shares of Common Stock. See "Principal Shareholders." In addition,
as noted above, four of the six members of the Board are also employees of the
Private Equity Investors. Accordingly, the Private Equity Investors and their
affiliates will be able to determine the outcome of all corporate actions
requiring approval by the members of the Board or shareholders and will be able
to control the election of the members of the Board and the determination of the
Company's policies. Such control may have the effect of delaying or preventing a
change in control of the Company.
 
                                       10
<PAGE>
DILUTION
 
    The Company has a net deficit in shareholders' equity and a net tangible
deficit. Purchasers of Common Stock in this offering will experience immediate
and substantial dilution in the net tangible book value of $         per share
based upon an assumed initial public offering price of $         per share. See
"Dilution."
 
    In addition, on September 6, 1995 the Company issued the Stock Purchase
Warrants to certain shareholders for the purchase of an aggregate of 641,236
shares of Common Stock at an exercise price of $.05 per share. Although the
Stock Purchase Warrants will not become exercisable upon the completion of this
offering, they will become exercisable if, on or prior to June 30, 1997 (or,
under certain conditions, prior to September 30, 1997), there occurs a sale of
the capital stock of the Company held by the Private Equity Investors or a
merger, consolidation or other business combination, such that the Private
Equity Investors receive cash proceeds (net of certain expenses and fees) that
exceed $75 million for their shares of Common Stock. See "Certain
Transactions--1995 Transaction" and "Capitalization." If the Stock Purchase
Warrants are exercised, all shareholders purchasing in this offering would
experience further additional dilution as up to 641,236 shares of Common Stock
would become outstanding.
 
NO PRIOR MARKET; POTENTIAL VOLATILITY
 
    Prior to this offering, there has been no public market for the Common
Stock, and there can be no assurance that an active trading market will develop
or be sustained after this offering. The initial public offering price will be
determined by negotiation among the Company and the Representative of the
Underwriters and may not be indicative of prices that will prevail in the
trading market. Consequently, there can be no assurance that the market price
for the Common Stock will not fall below the public offering price. See
"Underwriters" for a discussion of the factors to be considered in determining
the initial public offering price. Although application has been made to have
the Common Stock listed on the Nasdaq National Market, there can be no assurance
that an active public market will develop or, if developed, will be sustained
following this offering. There has been significant volatility in the market
price of securities of companies involved in the health care industry that often
has been unrelated to the operating performance of such companies. The Company
believes that certain factors, such as legislative and regulatory developments,
lower revenues or earnings than those anticipated by securities analysts, the
overall economy and the financial markets, could cause the price of the Common
Stock to fluctuate substantially.
 
SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT ON MARKET PRICE
 
    4,262,147 shares representing 63% of the number of shares of Common Stock
outstanding after the completion of this offering are or will be eligible for
future sale in the public market at prescribed times pursuant to Rule 144 or
Rule 701 under the Securities Act of 1933, as amended (the "Securities Act"), or
pursuant to the exercise of registration rights. Sales of such shares in the
public market, or the perception that such sales may occur, could adversely
affect the market price of the Common Stock or impair the Company's ability to
raise additional capital in the future through the sale of equity securities.
See "--Dilution," "Shares Eligible for Future Sale," "Underwriters" and
"Description of Capital Stock--Registration Rights."
 
ANTI-TAKEOVER CONSIDERATIONS
 
    Certain provisions of the Company's Articles of Incorporation and Bylaws and
the Illinois Business Corporation Act of 1983 ("IBCA") could, together or
separately, discourage potential acquisition proposals or delay or prevent a
change in control of the Company, even when shareholders, other than the Private
Equity Investors, consider such a transaction to be in their best interest.
Accordingly, such provisions may limit the price that certain investors might be
willing to pay in the future for shares of the Common Stock. See "--Material
Benefit to Insiders; Control by Private Equity Investors," "Description of
Capital Stock--Preferred Stock" and "Description of Capital Stock--Illinois
Takeover Statute." In addition, the equity ownership position of, and control of
the Board by, the Private Equity Investors may have the effect of delaying or
preventing a change in control of the Company. See "-- Material Benefit to
Insiders; Control by Private Equity Investors."

                                  THE COMPANY
 
    UtiliMed is the nation's leading manager of diagnostic imaging services,
providing a comprehensive approach to managing cost, quality and utilization for
payors with large memberships. The Company's products aim to manage the delivery
of quality necessary diagnostic imaging services by qualified physicians to
patients on a cost effective basis. UtiliMed's products manage costs by
decreasing the volume and increasing the quality of imaging services. Quality
improvement can decrease costs through fewer repeat or extra exams necessitated
by poor quality initial exams. The Company offers its clients a capitated
product and a fee-based product, each of which is designed to reduce excess or
improper utilization and improve the quality of service. The core program
elements of the Company's two products include diagnostic imaging assessment and
privileging, diagnostic imaging pre-certification processes, clinical- and
claims-based retrospective utilization database tools and structured physician
education.
 
    In November 1994, the Company redeemed outstanding shares of capital stock
from then existing management. To finance this transaction, the Company issued
debt in the principal amount of $10 million and shares of Common Stock and
instruments convertible into Common Stock to the Private Equity Investors. The
redemption and investment (together, the "Recapitalization") were undertaken to
provide limited liquidity for certain of the Company's founders, to align the
organizational and capital structure of the Company with that of other private
companies that have professional investors, to attract experienced and qualified
directors, to access the financial and managerial advice and experience of the
Private Equity Investors and to facilitate capital investment by other
professional investors that would not ordinarily invest in a closely-held
company. See "Certain Transactions-- Recapitalization."
 
    Following the Recapitalization, the Company grew rapidly in terms of gross
revenues derived from new CDIP contracts. During the third quarter of 1995,
however, the then existing management and the Private Equity Investors
recognized significant problems in managing the rapid growth of the business and
that the financial condition of the Company had deteriorated during 1995 as
evidenced by substantial operating losses. As a result, the Private Equity
Investors and certain shareholders of the Company completed a capital
transaction in September 1995 that resulted in changes to the capitalization,
management and business of the Company (collectively, the "1995 Transaction").
In connection with the 1995 Transaction, a new management team, led by Dr. Carl
Adkins, the former CEO of United HealthCare of Ohio-Western Region (a subsidiary
of United HealthCare, Inc.), was asssembled. Since the new management team was
assembled, the Company has improved its operating condition through the
implementation of certain initiatives: implementation of the RMP product, the
Terminated Contracts, the renegotiation of six continuing CDIP contracts, and
the recruitment of new professional leadership in finance, operations, claims
management and professional relations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations," "Business-Strategy" and
"Certain Transactions--1995 Transaction."
 
    The Company was incorporated in Illinois in December 1989. On May 22, 1996,
the Company changed its name from Medicon, Inc. to UtiliMed, Inc. The principal
executive offices of the Company are located at 40 Skokie Boulevard, Northbrook,
Illinois 60062-1618 and its telephone number is (847) 564-8500.
 
                                DIVIDEND POLICY
 
    The Company has never declared or paid any dividend on its Common Stock
since its incorporation and does not expect to pay cash dividends on its Common
Stock in the foreseeable future. The Company currently intends to retain all of
its earnings for the operation and expansion of its business. Payment of any
future dividends will depend on the profitability, future earnings and working
capital requirements

of the Company and other factors that the Board considers appropriate. See "Risk
Factors--Shareholders' Deficit; History of Operating Losses" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
                                USE OF PROCEEDS
 
    The net proceeds to be received by the Company from the sale of the Common
Stock offered hereby, based on an assumed initial public offering price of
$         per share, are estimated to be approximately $         million (or
approximately $         million if the Underwriters' over-allotment option is
exercised in full). Approximately $17.6 million of the net proceeds will be used
to repay indebtedness, approximately $1 million will be used for certain
computer hardware enhancements (including the upgrade and purchase of
equipment), and the balance will be used for working capital. Of the net
proceeds to be used to repay indebtedness, approximately $6.1 million will be
used to repay the principal of and accrued interest on the Senior Notes due
March 6, 1997 which have a variable interest rate and currently bear interest at
14% per annum issued to CCP and Whitney; $1 million to pay certain associated
deferred fees to CCP and Whitney incurred in connection with the issuance of the
Senior Notes; approximately $10.1 million to repay the principal of and accrued
interest on the Senior Subordinated Notes due November 3, 2001 issued to CCP and
Whitney Debt Fund and bearing interest at 10.101% per annum (see "Certain
Transactions" and "Risk Factors--Material Benefit to Insiders; Control by
Private Equity Investors"); and approximately $416,000 to repay the principal of
and accrued interest on a promissory note issued by the Company to Jack M.
Korsower, M.D. (the "Korsower Note") that matures by its terms upon the
consummation of this offering and bears interest at 8.5% per annum. See "Certain
Transactions--1995 Transaction." Approximately $   million of the net proceeds
will be used to achieve positive working capital to support the implementation
of the Company's growth strategy. These funds are expected to remain invested in
short-term investment grade interest bearing securities. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

                                 CAPITALIZATION
 
    The following table sets forth the (i) the capitalization of the Company at
March 31, 1996 (as if the 5.361849 for-one-reverse stock split declared by the
Board and the conversion of the $10.6 million principal amount Junior
Subordinated Promissory Notes (the "Junior Subordinated Notes") issued in
connection with the Recapitalization into 94,039 shares of Common Stock in
accordance with the terms thereof had occurred prior to March 31, 1996); (ii)
the pro forma capitalization as of such date, after giving effect to (a) the
conversion of the Series A Preferred Stock, no par value (the "Series A
Preferred Stock") and the Class B Stock, no par value (the "Class B Stock") into
3,231,507 shares of Common Stock and (b) the authorization by the Board on
            , 1996 of a new class of preferred stock (see "Certain Transactions"
and "Description of Capital Stock"); and (iii) as adjusted to give effect to the
issuance of 2,500,000 shares of Common Stock offered hereby and the application
of the net proceeds therefrom as described under "Use of Proceeds." This table

                                    DILUTION
 
    The deficit in net tangible book value of the Company at March 31, 1996, was
approximately $62.9 million or $14.75 per share, as determined by dividing the
Company's total tangible assets less total liabilities by the number of shares
of Common Stock outstanding at that date (assuming conversion of the Company's
Series A Convertible Preferred Stock and Class B Stock into shares of Common
Stock). The pro forma net tangible book value of the Company at March 31, 1996,
would have been approximately $   million or $         per share after giving
effect to this offering (at an assumed initial public offering price of
$         per share) and the application of the estimated net proceeds to the
Company therefrom as set forth in "Use of Proceeds." This represents an
immediate increase of $         per share in the net tangible book value to
existing holders of the Common Stock and an immediate dilution in net tangible
book value of $         per share to new investors purchasing shares of Common
Stock in this offering. "Dilution in net tangible book value" means the
difference between the price per share paid by investors purchasing shares of
Common Stock in this offering and the deficit in pro forma net tangible book
value per share at March 31, 1996. The following table illustrates this per
share dilution:

(1) Represents seven CDIP contracts that were terminated in 1995 (the
    "Terminated Contracts"). Five of the Terminated Contracts were unprofitable
    contracts terminated by the Company's new management team as part of the
    initiatives being implemented subsequent to the 1995 Transaction (as defined
    herein). These unprofitable contracts were entered into without
    establishment of appropriate provider networks, thereby placing the Company
    at significant financial risk. The other two Terminated Contracts were
    terminated prior to their completion by mutual agreement of the Company and
    the client. See "Management's Discussion and Analysis of Financial Condition
    and Results of Operations" and "Business-- Clients; Capitation Contracts and
    Provider Contracts; RMP Contracts."
 
(2) Net loss per share is computed by dividing net loss by the number of common
    and common equivalent shares outstanding during the periods in accordance
    with the applicable rules of the Commission. All stock options and
    restricted common stock issued have been considered as outstanding common
    stock equivalents for all periods presented, even if anti-dilutive, under
    the treasury stock method (based on initial public offering price). Shares
    of common stock issuable upon conversion of the Series A Preferred Stock and
    Class B Stock are assumed to be common share equivalents for all periods
    presented.
 
(3) The December 31, 1992 total assets include $157,000 of deferred contract
    development costs.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    The Company derives its revenue and operating income from service contracts
with clients for the management of diagnostic imaging services. The Company
offers a capitated product, CDIP, as well as a fee-based product, RMP. Under
each of these products, the Company receives a fixed per member per month
("pmpm") payment in return for the provision of services. In connection with the
1995 Transaction, five unprofitable contracts with unfavorable terms were
terminated by the Company in the third and fourth quarters of 1995. In addition,
two other CDIP contracts were terminated during 1995. All seven of such
contracts are referred to herein as the "Terminated Contracts." See "Selected
Consolidated Financial Information." The following table sets forth the number
of covered lives and contracts managed by the Company as of the dates indicated:

    indicated, covered lives in this table and this Prospectus are rounded to
    the nearest thousand.
 
(2) In addition, the Company signed a new RMP contract in March 1996 covering
    220,000 million lives which will be implemented in June 1996.
 
    During the third quarter of 1995, the then existing management and the
Private Equity Investors recognized that there were significant problems
managing the rapid growth of the business and that the financial condition of
the Company had deteriorated during 1995 as evidenced by substantial operating
losses. As a result of the rapid growth of the Company, inadequate financial
performance and limited experience of the then existing management, the Company
began implementing the following business initiatives in the third quarter of
1995:
 
    . A new Chief Executive Officer was hired.
 
    . New, more experienced professionals were recruited in operations, claims
      management, finance and client relations and a new management team was
      assembled.
 
    . A new operating strategy was developed that focused on (i) introducing the
      new RMP product; (ii) expanding the CDIP product; (iii) evaluating the
      current and future profitability of all existing contracts; (iv) reducing
      operating costs and (v) improving financial controls.
 
    . Five unprofitable contracts which had unfavorable terms were terminated.
 
    . The Company initiated discussions to renegotiate six other contracts in an
      effort to improve the profitability of such contracts. Two of such
      contract renegotiations were completed on favorable terms, two additional
      renegotiations are substantially completed, and two are in process.

    . General and administrative expenses were reduced through a 15.6% reduction
      in the workforce from 224 full-time employees at June 30, 1995 to 189
      full-time employees at March 31, 1996. In addition, expense controls were
      implemented in other areas such as travel, legal, consulting, printing and
      temporary services. As a result, the Company reduced its selling, general
      and administrative expenses by 20.9% for the quarter ended March 31, 1996
      compared to the quarter ended June 30, 1995.
 
    . The Company developed and implemented an activity-based cost model for
      evaluating potential business opportunities and improving financial
      forecasting.
 
    As a result of the ongoing implementation of these initiatives, the Company
has positioned itself for improved financial results. However, there can be no
assurance that the Company will be successful in continuing to improve its
financial performance.
 
REVENUE
 
    The Company receives revenue in the form of pmpm payments from clients
pursuant to CDIP and RMP contracts with terms of one to five years. The pmpm
payment received under CDIP contracts includes an administrative fee associated
with the Company's management services and compensation for assuming the
responsibility for medical costs and claims processing related to the provision
of diagnostic imaging services. Eight of the CDIP contracts allow for annual
changes of the pmpm payment tied to changes in the Consumer Price Index ("CPI").
The pmpm received under RMP contracts consists solely of an administrative fee
associated with the Company's management services. Consequently, pmpm revenue
from the CDIP contracts is significantly greater than pmpm revenue from RMP
contracts.
 
    Under RMP, the Company does not process claims for payments to providers
and, consequently, the RMP pmpm payment consists solely of an administrative fee
associated with the Company's management services. The Company includes an
incentive arrangement in its RMP contracts, whereby the Company and the client
set mutually agreed upon goals for achieving cost savings for the covered
population as a whole after the implementation of certain operational changes by
the client. In the event cost savings for the client exceed specified levels,
the Company and the client share in the savings. If the cost savings are not
achieved after the client has implemented certain operational changes, the
Company may be required to refund a portion, or in two RMP contracts, up to all
of the monthly pmpm payment. Under two RMP contracts, performance settlement is
made on an annual basis. A third RMP contract requires performance settlement at
the end of the three year term of the contract, with an interim settlement on or
about the second anniversary date of the contract. The fourth RMP contract does
not include an incentive arrangement nor is the pmpm payment subject to
reduction or refund. The Company's policy with RMP contracts is to accrue for
estimated incentive payments to the Company or refunds by the Company which may
be received or incurred, respectively, in accordance with the terms of each
contract. Because the RMP contracts are new, no such accruals have yet been
recognized. The Company intends to accrue for each RMP contract, if required,
once the client implements certain operational changes and experience patterns
are developed and identified. Adjustments relating to the accruals may be
material to the operating results of the Company.
 
    Growth in revenue is expected to be achieved primarily through securing and
implementing new RMP and CDIP contracts. The Company believes that growth in
revenue will also be achieved through membership growth of its existing client
base, expanding relationships with current clients and by expanding program
offerings with health plans for additional population segments. See "Business--
Strategy."
 
EXPENSES
 
    As a result of different program designs and financial risks, CDIP and RMP
have different expense levels. Under the CDIP contracts, the Company assumes the
responsibility for the processing and payment of claims for the provision of
diagnostic imaging services. These payments, which are cost of
 
                                       18
<PAGE>
services, are generally made to providers on a monthly basis in accordance with
the provider contracts and payment methodologies. Under certain payment
methodologies, providers receive additional reimbursement on a quarterly or
annual basis. See "Business--Clients; Capitation Contracts and Provider
Contracts; RMP Contracts."
 
    Payables to plans and providers under CDIP contracts include estimates of
unpaid reported and unreported services provided, accrued capitation fees and
adjustments. These estimates of payables are based on statistical information
and revised as additional information becomes available. Actual results
inevitably will differ from these estimates and such differences may have a
material effect on the Company's business, financial condition and results of
operations for a particular period. See Notes 1 and 3 to the Consolidated
Financial Statements. The Company's medical loss ratio (which is calculated as
cost of services divided by contract revenue, excluding RMP revenue) includes
both the actual payments made to providers and the estimate of amounts which
have been earned by providers but are either unpaid by or not yet reported to
the Company. Accordingly, while the Company's CDIP revenues are primarily fixed,
the cost of services will vary based upon the services rendered, the estimates
of payables and the contractual relationship with the provider.
 
    Selling, general and administrative expenses include the costs of client
relations, clinical coding, claims processing, precertification, assessment,
provider services, utilization analysis and fixed costs such as information
systems, finance, marketing, administration, human resources and legal expenses.
Generally, CDIP contract expenses are higher than RMP expenses because of the
additional costs associated with claims processing and payment and provider
network management.
 
    The Company incurs start-up costs before implementation of contracts, which
are expensed as incurred. Such costs, which include contracting provider
networks, interfacing of information systems and provider assessment and
training of new employees, are typically expensed beginning at least three
months prior to the initial recognition of revenue under a new contract. See
Note 1 to the Consolidated Financial Statements. Although RMP contracts do not
involve the cost of contracting provider networks, the cost of interfacing
information systems tends to be greater for RMP than for CDIP. Certain start-up
costs of CDIP and RMP contracts vary as a function of the size of the membership
of the client.
 
NET OPERATING LOSS CARRYFORWARDS
 
    The Company's net operating loss carryforwards of $13.7 million, which will
expire in the years 2009 and 2010, are available to offset future taxable
income. See Note 5 to the Consolidated Financial Statements.

(1) Total 1994 cost of services includes a charge of $3.2 million related to the
    estimated cost of services in excess of revenues for four contracts, two of
    which are Terminated Contracts, one of which has been renegotiated and the
    other is being renegotiated. Total 1995 cost of services includes a $1.7
    million reduction in cost of services related to the change in estimate
    arising from the early termination of the two Terminated Contracts.
 
THREE MONTHS ENDED MARCH 31, 1996 AND 1995
REVENUE
 
    Revenue from continuing contracts increased from $18.1 million in the
quarter ended March 31, 1995 to $24.1 million in the quarter ended March 31,
1996, an increase of $6.0 million or 33.1%. Of this increase, $1.7 million was
attributable to the addition of one CDIP contract in the first quarter of 1996.
The introduction of the RMP product resulted in the implementation of three RMP
contracts in the third and fourth quarters of 1995 which generated revenue of
$2.1 million in the first quarter of 1996. The remainder relates to increases in
the number of covered lives under continuing contracts. The total number of
covered lives managed under CDIP contracts increased by 25.7% from March 31,
1995 to 1,380,000 at March 31, 1996. The covered lives under RMP contracts
aggregated 1,166,000 at March 31, 1996.
 
    Revenue from Terminated Contracts decreased from $8.6 million in the quarter
ended March 31, 1995 to $0 in the quarter ended March 31, 1996 because revenues
from these contracts ended in 1995.
 
                                       20
<PAGE>
    COST OF SERVICES
 
    Cost of services for continuing contracts was $20.6 million, or 85.8% of
continuing contract revenue, in the first quarter of 1996 compared to $17.9
million, or 98.5%, in the first quarter of 1995. The decrease in cost of
services as a percentage of continuing contract revenue resulted from the
addition of three RMP contracts in the third and fourth quarters of 1995, which
do not have the cost of services component of CDIP, and an improved medical loss
ratio. The medical loss ratio improved to 94.0% in the first quarter of 1996
compared to 98.5% for the comparable quarter in 1995 primarily due to cost
reductions on three contracts.
 
    Cost of service for Terminated Contracts was $0 in the first quarter of 1996
compared to $9.0 million in the first quarter of 1995. No cost of services for
Terminated Contracts was incurred in the first quarter of 1996 because these
contracts were terminated in 1995.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSE
 
    Selling, general and administrative expenses decreased to $4.1 million, or
17.1% of total contract revenue, in the first quarter of 1996, compared to $4.8
million, or 18.0%, in the first quarter of 1995.
 
    Salaries, wages and related employee expenses were $3.2 million, or 13.2% of
total revenue, in the first quarter of 1996 compared to $3.1 million, or 11.6%,
in the first quarter of 1995. The increase of $.1 million resulted from the
increase in compensation expense related to employee restricted common stock
agreements offset in part by lower hiring expenses. The Company also did not
incur the level of expenses related to severance that was incurred in the second
half of 1995.
 
    Outside services expense, which consists primarily of management consulting,
information systems consulting, temporary labor and legal, audit and tax costs
was $187,000, or 0.8% of total revenue, in the first quarter of 1996 compared to
$555,000, or 2.1%, in the first quarter of 1995. The decrease of $368,000
resulted primarily from temporary labor and management consulting costs. The
Company does not anticipate that the levels of temporary labor and management
consulting costs incurred in 1995 will be representative of expenditures for
such items in 1996.
 
    Other selling, general and administrative expenses, which primarily consist
of travel, rent, printing, communications and marketing were $749,000, or 3.1%
of total revenue, in the first quarter of 1996 compared to $1.1 million, or
4.3%, in the first quarter of 1995. The decrease in the first quarter of 1996
resulted primarily from continued implementation of the new business
initiatives.
 
    DEPRECIATION AND AMORTIZATION
 
    Depreciation and amortization expense was $210,000 or 0.9% of total revenue,
in the first quarter of 1996 compared to $163,000, or 0.6%, in the first quarter
of 1995. Depreciation and amortization expense increased primarily due to
capital expenditures relating to office equipment, computer hardware and
software, and leasehold improvements.
 
    INTEREST EXPENSE
 
    Interest expense decreased to $419,000, or 1.7% of total revenue, in the
first quarter of 1996 compared to $592,000, or 2.2%, in the first quarter of
1995. The decrease in interest expense resulted primarily from the conversion of
the Junior Subordinated Notes into Common Stock. See "Certain Transactions--1995
Transaction."
 
    INTEREST INCOME
 
    Interest income decreased to $144,000, or 0.6% of total revenue, in the
first quarter of 1996 compared to $258,000, or 1.0%, in the first quarter of
1995. This decrease resulted primarily from decreased interest from short-term
investments.
 
                                       21
<PAGE>
    NET LOSS
 
    As a result of the foregoing, the Company incurred a net loss for the first
quarter of 1996 of $1.2 million compared to a net loss of $5.4 million for the
first quarter of 1995. The first quarter of 1996 represented an improvement in
financial performance which resulted from several factors that the Company
expects to continue. These factors include improvement in the medical loss ratio
due to decreased payments for out-of-network costs and improved management of
in-network costs, new RMP and CDIP contracts and realization of the effects of
the cost reduction initiative. Since the effect of these factors is ongoing,
there can be no assurance that such improvements will continue or that the
Company will become profitable.
 
YEARS ENDED DECEMBER 31, 1995 AND 1994
REVENUE
 
    Revenue from continuing contracts increased from $50.9 million in 1994 to
$76.5 million in 1995, an increase of $25.6 million or 50.3%. Of this increase,
$21.3 million was related to services provided for a full year under CDIP
contracts entered into with three clients during 1994. The introduction of RMP
in the third quarter of 1995 resulted in three new RMP contracts which generated
revenue of $1.8 million. The remaining $2.5 million resulted from increases in
revenue from existing CDIP contracts related to increases in the number of
covered lives under clients' plans and, to a lesser extent, annual CPI-based
increases in pmpm rates in CDIP contracts. The number of lives managed under
continuing CDIP contracts increased by 11.3%, from 1,035,000 at December 31,
1994 to 1,152,000 at December 31, 1995. Covered lives under three RMP contracts
aggregated 1,111,000 at December 31, 1995.
 
    Revenue from Terminated Contracts increased from $15.7 million in 1994 to
$20.0 million in 1995, an increase of $4.3 million or 27.4%. This increase
resulted primarily from two contracts which commenced operations in the fourth
quarter of 1994 and were in effect for the first three quarters of 1995 and two
contracts which commenced and were terminated in 1995. Such increase was offset
in part by a decline in revenue from a contract which was terminated in 1995,
but was in effect for all of 1994.
 
    COST OF SERVICES
 
    Cost of services for continuing contracts was $72.4 million, or 94.6% of
continuing contract revenue, in 1995 compared to $49.8 million, or 97.9%, in
1994. This increase was primarily attributable to services provided for a full
year under those CDIP contracts implemented in 1994. The decrease in cost of
services as a percentage of total revenue in 1995 resulted from the addition of
three RMP contracts during 1995 which do not have the cost of services component
of CDIP and an improved medical loss ratio. The medical loss ratio for CDIP
contracts improved from 97.9% during 1994 to 96.9% during 1995 primarily due to
cost reductions on two such contracts. In the fourth quarter of 1994, the
Company recognized cost of services in excess of revenue of $1.7 million for
such contracts through an estimated termination date. One of these contracts was
successfully renegotiated in 1996 and the Company is renegotiating the other
contract.
 
    Cost of services for Terminated Contracts was $18.4 million, or 92.4% of
Terminated Contract revenue, in 1995 compared to $16.7 million, or 106.4%, in
1994. In the fourth quarter of 1994, the Company recognized (i) cost of services
in excess of revenue on two CDIP contracts of $961,000 and (ii) estimated cost
of services in excess of revenues of $1.5 million for these two contracts
through estimated termination dates. As a result of the initiatives which the
Company began implementing in the third quarter of 1995, the two contracts were
terminated earlier than originally estimated. Consequently, the Company incurred
$1.7 million less costs of services than originally estimated. Excluding the
impact of these adjustments, cost of services was 100.8% of Terminated Contract
revenue in 1995 compared to 90.1% for 1994. This increase as a percentage of
revenue resulted primarily from cost overruns associated with one Terminated
Contract which commenced operations in 1995.
 
                                       22
<PAGE>
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general and administrative expenses increased to $22.0 million, or
22.8% of total revenue, in 1995 compared to $13.2 million, or 19.9% of total
revenue, in 1994.
 
    Salaries, wages and related employee benefits and expenses were $14.1
million, or 14.7% of total revenue, in 1995 compared to $9.1 million, or 13.7%,
in 1994. This increase was attributable to the addition of personnel to support
the Company's revenue growth. Also, as a result of the initiatives the Company
began implementing in the third quarter of 1995, salaries, wages and benefits
costs increased in 1995 as a result of severance and hiring expenses, each of
which represented $1.1 million, or 1.1% of total revenue, in 1995. The Company
considers the amount of these expenses to be non-recurring.
 
    Outside services expense, which primarily consists of management consulting,
information systems consulting, temporary labor and legal, audit and tax costs
was $3.5 million, or 3.7% of total revenue, in 1995 compared to $1.4 million, or
2.1%, in 1994. The increase in outside services expense resulted primarily from
information systems consulting and costs associated with implementing the
Company's new business initiatives.
 
    Other selling, general and administrative expenses, which primarily consist
of travel, rent, bad debts, printing, communications and marketing were $4.3
million, or 4.4%, in 1995 compared to $2.7 million, or 4.1%, in 1994. The
increase in other selling, general and administrative expenses resulted
primarily from greater support costs associated with the Company's revenue
growth. In addition, the Company expensed a $482,000 account receivable related
to a joint venture established in connection with one of the Terminated
Contracts.
 
    DEPRECIATION AND AMORTIZATION
 
    Depreciation and amortization expense was $740,000, or 0.8% of total
revenue, in 1995 compared to $493,000, or 0.7%, in 1994. Depreciation and
amortization expense increased due to the expansion of office facilities and
related leasehold improvements, as well as increased capital expenditures for
computer equipment and software.
 
    INTEREST EXPENSE
 
    Interest expense increased to $2.1 million, or 2.1% of total revenue, in
1995 compared to $572,000, or 0.8%, in 1994. The increase resulted from
additional long-term debt, including the Senior Subordinated Notes and the
Junior Subordinated Notes issued in November 1994 and capitalized lease
obligations. At December 31, 1995, long-term debt, including the Senior
Subordinated Notes and the Junior Subordinated Notes and capitalized lease
obligations, decreased $14.2 million, of which $10.6 million was attributable to
the conversion of Junior Subordinated Notes into Common Stock. See "Certain
Transactions--1995 Transaction" and Note 4 to the Consolidated Financial
Statements.
 
    INTEREST INCOME
 
    Interest income increased to $700,000, or 0.7% of total revenue, in 1995
compared to $311,000, or 0.5%, in 1994. This increase resulted from additional
interest from short-term investments.
 
    NET LOSS
 
    As a result of the foregoing, the net loss for 1995 was $18.8 million
compared to $13.9 million for 1994.

    Revenue from continuing contracts increased from $19.3 million in 1993 to
$50.9 million in 1994, an increase of $31.6 million or 163.7%. Of this increase,
$18.4 million was attributable to the addition of three CDIP contracts in 1994
and $11.7 million was related to services provided for a full year under CDIP
contracts entered into with four clients during 1993. The remaining $1.8 million
was the result of
 
                                       23
<PAGE>
increases in revenue from existing contracts related to increases in the number
of covered lives under clients' plans and, to a lesser extent, increases in
capitated rates received by the Company. The number of lives managed under CDIP
agreements increased by 113.4% from 485,000 at December 31, 1993 to 1,035,000 at
December 31, 1994.
 
    Revenue from Terminated Contracts increased from $7.1 million in 1993 to
$15.7 million in 1994, an increase of $8.6 million or 121.1%. This increase
resulted primarily from three contracts which commenced operations in 1994.
 
    COST OF SERVICES
 
    Cost of services for continuing contracts was $49.8 million, or 97.9% of
continuing contract revenue, in 1994 compared to $16.9 million, or 87.6%, in
1993. This increase was primarily attributable to services provided for a full
year under four CDIP contracts implemented in 1993. The increase in cost of
services as a percentage of continuing contract revenue in 1994 was primarily
attributable to cost of services in excess of revenue of $1.7 million, of which
one contract has subsequently been renegotiated. The remaining increase resulted
primarily from two contracts which had significantly higher medical loss ratios
than other continuing contracts, one of which commenced operations during 1994
and a second contract that commenced operations during the fourth quarter of
1993.
 
    Cost of services for Terminated Contracts was $16.7 million, or 106.4% of
Terminated Contract revenue, in 1994 compared to $5.8 million, or 81.7%, in
1993. In the fourth quarter of 1994, the Company recognized (i) cost of services
in excess of revenues on two CDIP contracts of $961,000 and (ii) estimated cost
of services in excess of revenues of $1.5 million for these two contracts
through estimated termination dates. Excluding the impact of these adjustments,
cost of services was 90.1% of Terminated Contract revenue in 1994 compared to
81.7% in 1993. This increase resulted primarily from an increase in the medical
loss ratio for one Terminated Contract.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general and administrative expenses increased to $13.2 million,
19.9% of total revenue, in 1994 compared to $6.1 million, or 23.2% of total
revenue, in 1993.
 
    Salaries, wages and related employee benefits and expenses remained
relatively consistent as a percentage of total revenue from 1993 to 1994. These
expenses were $9.1 million, or 13.7% of total revenue, in 1994 compared to $3.8
million, or 14.4%, in 1993. This increase of $5.4 million is primarily
attributable to an increase in the number of employees from 110 at December 31,
1993 to 172 at December 31, 1994.
 
    Outside services expense, which primarily consists of temporary labor,
management consulting, information systems consulting, and legal, audit and tax
costs was $1.4 million, or 2.1% of total revenue, in 1994 compared to $692,000,
or 2.6%, in 1993. The increase in outside services expense resulted primarily
from management consulting and information systems consulting to support the
Company's revenue growth.
 
    Other selling, general and administrative expenses, which primarily consist
of travel, rent, printing, communications and marketing, were $2.7 million, or
4.1% of total revenue, in 1994 compared to $1.6 million, or 6.1%, in 1993. The
decrease as a percentage of total revenue resulted from operating efficiencies
achieved through revenue growth.
 
    DEPRECIATION AND AMORTIZATION
 
    Depreciation and amortization expense was $493,000, or 0.7% of total
revenue, in 1994 compared to $209,000, or 0.8%, in 1993. The increase in
depreciation and amortization expense resulted from the expansion of office
facilities and related leasehold improvements, as well as increased capital
expenditures for computer equipment and software.
 
                                       24
<PAGE>
    INTEREST EXPENSE
 
    Interest expense increased to $572,000, or 0.8% of total revenue, in 1994
compared to $41,000, or 0.1%, in 1993. The increase in interest expense resulted
from additional long-term debt, including the Senior Subordinated Notes and the
Junior Subordinated Notes issued in November 1994 and capitalized lease
obligations. Long-term debt increased from $.7 million at December 31, 1993 to
$24.7 million at December 31, 1994. See "Certain
Transactions--Recapitalization."
 
    INTEREST INCOME
 
    Interest income increased to $311,000, or 0.5% of total revenue, in 1994
compared to $58,000, or 0.2%, in 1993. This increase resulted from additional
interest from short-term investments.
 
    NET LOSS
 
    As a result of the foregoing, the net loss was $13.9 million in 1994
compared to $2.6 million for 1993.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At March 31, 1996, the Company had a working capital deficit of $19.8
million and a total shareholders' deficit of $62.9 million. Of the net proceeds
of this offering, approximately $17.6 million will be used to repay
indebtedness, approximately $1 million will be used for certain computer
hardware and software enhancements (including the upgrade and purchase of
equipment), and the balance will be used for working capital. Of the net
proceeds to be used to repay indebtedness, approximately $6.1 million will be
used to repay the principal of and accrued interest on the Senior Notes; $1
million to pay certain associated deferred fees to CCP and Whitney incurred in
connection with the issuance of the Senior Notes; approximately $10.1 million to
repay the principal of and accrued interest on the Senior Subordinated Notes;
and approximately $416,000 to repay the principal of and accrued interest on the
Korsower Note. Approximately $   million of the net proceeds will be used to
achieve positive working capital to support the implementation of the Company's
growth strategy. These funds are expected to remain invested in short-term
investment grade interest bearing securities. See "Use of Proceeds."
 
    Immediately prior to consummation of this offering, the outstanding shares
of Series A Preferred Stock and Class B Stock will be converted into shares of
Common Stock. On a pro forma as adjusted basis at March 31, 1996, assuming such
conversion and application of the proceeds from this offering, the Company would
have had positive working capital, total indebtedness would have been reduced
from $17.8 million to approximately $507,000 and shareholders' equity would have
increased from a deficit of $62.9 million to positive shareholders' equity of
approximately $   million. See "Capitalization"
 
    The Company's historical operating cash requirements have been met through a
combination of cash provided by operating activities, financing from
shareholders and a bank line of credit which was discontinued. See "Certain
Transactions". Net cash provided from operating activities was $2.0 million and
$2.9 million for the years ended December 31, 1993 and 1994, respectively,
compared to $13.9 million of cash used in operating activities for the year
ended December 31, 1995. Although the Company had a net loss of $13.9 million in
1994, the increase in payables to providers of $16.7 million contributed to the
overall increase in cash flow from operations. The negative cash flow for 1995
was primarily related to the Company's net loss of $18.8 million.
 
    The Company's primary cash need is to pay provider diagnostic imaging claims
under CDIP agreements. The total amount due to providers was $20.6 million at
December 31, 1995, compared to $18.4 million at December 31, 1994 and $22.3
million at March 31, 1996. As the number of CDIP contracts increases, these
obligations will increase. In addition, the Company has been required to service
outstanding debt due to the Private Equity Investors, which aggregated $10.0
million at December 31, 1995 and $17.0 million at March 31, 1996, including a
$1.0 million transaction fee. A portion of the net proceeds of this offering
will be used to repay this indebtedness.
 
                                       25
<PAGE>
    Certain of the Company's RMP contracts include various performance criteria.
If these performance criteria are not met, the Company may be obligated to
refund a portion or all of the administrative fees received. Failure to achieve
contractual performance criteria could have a material adverse effect on the
Company's cash flows.
 
    Capital expenditures for 1995, 1994 and 1993 were $1.4 million, $1.3 million
and $1.3 million, respectively. Such expenditures primarily consisted of office
equipment, leasehold improvements and computer hardware and software. Other than
the $1 million for planned computer hardware and software expenditures in 1996,
which will be funded by a portion of the net proceeds from this offering, the
Company does not expect to incur any significant capital expenditure in 1996.
 
    The Company believes that cash flow from operating activities and the net
proceeds from this offering will be sufficient to fund the Company's working
capital needs through the end of 1996. The Company believes it has positioned
itself for further improvement in financial performance as a result of the
business initiatives being implemented since the 1995 Transaction. If the
Company does not achieve sustained profitability, however, it may not have
sufficient operating cash flow to meet its working capital needs over the next
twelve months. There can be no assurance that the Company will become profitable
or that the Company will maintain working capital sufficient to support the
Company's operating cash requirements or growth strategy. While the Private
Equity Investors committed to provide up to $3 million in 1996 should such
support be necessary, the commitment will expire upon the consummation of this
offering. If the Company requires additional funds to support its working
capital requirements or for other purposes, it may seek to raise such funds
through public or private equity financings or from other sources. There can be
no assurance that additional financing will be available or, if available, that
such financing will be obtainable on terms favorable to the Company and would
not be dilutive.
 
    In addition to the Terminated Contracts, the Company has, in an effort to
improve profitability, engaged in renegotiations regarding six other CDIP
contracts. This effort has resulted in two contracts being renegotiated,
negotiations with respect to two additional contracts being substantially
completed and two others in process. As part of the renegotiations with respect
to one contract that is substantially completed, the Company agreed to deposit
with the client the amount of the estimated payable to providers affiliated with
such client. Until the return to the Company of the deposit, such funds are not
available to the Company for working capital or other purposes. See
"Business--Clients; Capitation Contracts and Provider Contracts; RMP Contracts"
and "Certain Transactions--Senior Notes." The Company believes that the terms of
the business agreement with such client, which are subject to definitive
documentation, will improve the profitability and cash flow from the contract
and will facilitate implementation of the initiatives to position the Company
for improved financial results.
 
    From 1993 to 1995, the Company maintained a credit line providing for
maximum borrowings of $700,000. This credit line was not extended by the Company
in January 1995 following the Recapitalization. While the Company anticipates
that it will obtain a credit facility following the consummation of this
offering, the Company has not engaged in negotiations and no assurance can be
given that a credit facility will be obtained on terms acceptable to the
Company.
 
    The Company's net operating loss carryforwards of $13.7 million, which
expire in the years 2009 and 2010, are available to offset future taxable
income. See Note 5 to the Consolidated Financial Statements. Upon the
consummation of this offering, the Company will incur non-recurring, non-cash
charges of $874,000 offset in part by a reversal of the valuation allowance of
$287,000 for loss on employee notes. See "Certain Transactions--1995
Transaction."
 
SUMMARY OF OPERATIONS BY QUARTER
 
    The following table presents unaudited quarterly operating results for the
periods indicated. The Company believes all necessary adjustments, consisting
only of normal, recurring adjustments, have been included in the amounts stated
below to present fairly the quarterly results when read in conjunction with the
Consolidated Financial Statements and the notes thereto included elsewhere in
this
 
                                       26

Prospectus. Future quarterly results may fluctuate depending on the timing and
number of new contracts and start-up costs associated therewith, adjustments
relating to the accruals for incentive payments under RMP contracts and
adjustments resulting from changes to estimates of cost of services attributable
to fees due to providers. Results of operations for any particular quarter are
not necessarily indicative of results of operations for a full year or
predictive of future periods.

    The fourth quarter of 1994 includes charges aggregating $3.2 million
relating to the estimated loss for four contracts through the estimated
termination dates. Two of the contracts were terminated in connection with the
1995 Transaction. One of the four contracts has been renegotiated and the fourth
contract is being renegotiated.
 
    The third quarter and fourth quarter of 1995 include an adjustment to the
estimated loss accrual recorded in the fourth quarter of 1994 of $1.5 million
and $.2 million, respectively. These adjustments were recognized as a reduction
in cost of services.
 
    During the third quarter of 1995, the Company began implementing certain
business initiatives and as a result, incurred severance expense of $481,000 and
$620,000 and hiring expenses of $440,000 and $181,000, all in the third and
fourth quarters, respectively.

INDUSTRY OVERVIEW
 
    Diagnostic imaging services include, among other techniques, ultrasound,
diagnostic radiology (including mammography), magnetic resonance imaging
("MRI"), computed tomography ("CT") and nuclear medicine. Diagnostic imaging in
many instances enables physicians to provide early diagnostic capability to aid
in effective treatment. The Company believes that a significant amount of
diagnostic imaging utilization and associated cost is unnecessary and can be
reduced through comprehensive management (including utilization, quality,
outcomes and network management), physician education, and data analysis that
generate significant cost savings and improve the quality and utilization of
diagnostic imaging services for payors. Historically, however, utilization and
cost levels of diagnostic imaging services have increased and been largely
unmanaged, with minimal outsourcing to diagnostic imaging managed care
companies.
 
    It is estimated that health care spending in the United States in 1994
amounted to approximately $1.06 trillion dollars, $604 billion of which was
attributable to payments to physicians and hospitals. Based on its analysis of
industry data, the Company believes that total expenditures on radiology
services (which include both therapeutic radiology and diagnostic imaging) in
1994 amounted to approximately $52.0 billion, including $6.1 billion by HMOs,
$9.1 billion by PPOs, $16.8 billion for Medicare, $17.5 billion by indemnity
insurers and $2.5 billion for Medicaid. The Company believes that diagnostic
imaging accounted for more than $47.8 billion, or 90.0%, of expenditures on
radiology services.
 
    The Company, based on an analysis of its own data, estimates that in the
period from 1993 to 1995, per capita utilization of diagnostic imaging
procedures rose approximately 19.0%. Increases in utilization and expenditures
are expected to continue as the average age of the population of the United
States and the demand for diagnostic imaging services increases. Advances in
medical technology resulting in additional diagnostic imaging services and
increasing patient awareness of the variety of such services are also expected
to contribute to increased utilization and expenditures. The Company estimates
that radiology services can account for 8 to 10% of payors' medical costs.
 
    The rapidly evolving managed health care environment has created substantial
economic pressures on payors and providers, leading to an increased focus on the
management of medical costs. In areas such as worker's compensation, dental
care, eye care and oncology, payors look to outsource to specialized third party
health care managers that provide expertise to generate cost savings through
increasing utilization efficiency. This expertise, coupled with access to a
broad base of regional and national data, enables such specialized health care
managers to control costs more effectively and provide payors and affiliated
physicians with reports that benchmark performance against the best practices in
a given industry. In addition, certain payors seek to transfer the financial
risk for changes in utilization levels and associated costs to such third party
managers, which are better able to manage risk because of the information and
expertise available to them.
 
    Diagnostic imaging represents a complex segment of the health care industry.
The Company believes that the provision of such services has proven difficult
for payors to manage or fit into a management system that comprehensively
addresses quality, utilization and cost control. The cost management challenge
is related to: (i) the diversity of providers performing diagnostic imaging
services (including radiologists, primary care physicians, pediatricians and
orthopedists); (ii) the varied settings for these services (e.g., hospitals,
outpatient facilities, physician offices); and (iii) the diversity of symptoms
and disease states. For instance, the Company estimates that approximately 50%
of the volume of outpatient diagnostic imaging services (other than mammography)
are performed in-office by non-radiologists such as primary care physicians and
medical, surgical and pediatrics specialists. In the complex and highly
fragmented diagnostic imaging environment, there are few companies that have the
expertise, data resources and ability to provide an integrated, comprehensive
approach to managing cost, quality and utilization.

    UtiliMed is the nation's leading manager of diagnostic imaging services,
providing a comprehensive approach to managing cost, quality and utilization for
payors with large memberships. The Company's products aim to manage the delivery
of quality necessary diagnostic imaging services by qualified physicians to
patients on a cost effective basis. UtiliMed's products manage costs by
decreasing the volume and improving the quality of imaging services. Quality
improvement can decrease costs through fewer repeat or extra exams necessitated
by poor quality initial exams. At March 31, 1996, the Company managed diagnostic
imaging services for 16 clients representing over 2.5 million lives in 13
states. In addition, the Company signed a new RMP contract in March 1996
covering 220,000 lives which will be implemented in June 1996.
 
    Founded in December 1989, the Company has achieved rapid growth, with
revenues having grown from approximately $2.5 million in 1991 to $96.4 million
in 1995 and covered lives having increased from 102,000 at December 31, 1991 to
2.5 million at March 31, 1996. The Company believes that an opportunity exists
for payors to reduce costs while maintaining quality through more effective
management of these services. As the leading comprehensive provider of
diagnostic imaging management services, the Company believes that it is well
positioned to take advantage of the relatively unpenetrated market for
outsourced management of diagnostic imaging services.
 
    The Company offers its clients a capitated product and a fee-based product,
each of which is designed to reduce unnecessary or inappropriate utilization and
improve the quality of service. The core program elements of the Company's two
products include diagnostic imaging assessment and privileging, diagnostic
imaging pre-certification processes, clinical- and claims-based retrospective
utilization database tools and structured physician education. Use of the
Company's capitated product can result in cost savings of 20% to clients within
the first year and the Company anticipates that the use of its fee-based network
management product will result in comparable savings to its clients in the first
year.
 
    In its Capitated Diagnostic Imaging Program ("CDIP"), the Company
establishes and maintains networks of diagnostic imaging providers which meet
the Company's assessment requirements and agree to receive payment from the
Company based on appropriate utilization levels and financial incentives. The
Company receives a pmpm fee, consisting of compensation for the assumption of
responsibility for medical costs and claims processing, and a fee for the
provision of network management services. By taking responsibility for the
payment of fees to physicians providing such services, the Company experiences
the benefits and risks resulting from variations in utilization levels and
associated medical costs--the capitation risk. Due to certain regulatory
requirements, the Company offers its CDIP product only to HMOs. See
"Business--Regulation."
 
    In its recently introduced Resource Management Program ("RMP"), the Company
provides network management services in return for a fee from participating
clients. RMP clients are responsible for establishing and maintaining networks
of physicians and retain risk for medical costs payable to physician providers.
The RMP fee does not include payment for medical costs since RMP does not alter
the payment relationship between UtiliMed clients and the providing physicians.
RMP, which includes the core product elements of CDIP, can be provided to a wide
range of payors, including HMOs, self-funded employers and indemnity insurers.
 
    The Company maintains a database of claims data, clinical reports and
assessment information which is an important tool for network and utilization
management. At March 31, 1996, the database contained claims data for over 8
million lives, assessment data for over 10,000 imaging sites and over one
million clinical reports. The number of monthly clinical reports added to the
database has grown from approximately 35,000 in March 1995 to approximately
54,000 in March 1996. The database enables the Company to develop protocols,
produce outcomes and benchmarking analyses (both provider-specific and
diagnosis-specific) and to create educational programs for physicians and other
providers. See "--Information Systems."

STRATEGY
 
    UtiliMed's objective is to enhance its leading position in diagnostic
imaging managed care services and continue its growth by pursuing a wide range
of significant new opportunities. The Company believes its ability to combine
utilization management, quality management, outcomes management and network
management provides an attractive alternative for payors in managing diagnostic
imaging services. The Company sees opportunities for growth both in establishing
new client relationships and expanding relationships with existing clients--by
extending coverage to additional local health plans of regional and national
payors, such as CIGNA and United HealthCare, Inc. and by serving additional
membership populations of existing clients, such as members covered under
Medicare and Medicaid programs. The Company will also seek to market RMP to
payors other than HMOs, such as self-funded employers and indemnity insurers,
and to market its products directly to large employer groups, benefits
administrators, and benefits consulting groups.
 
    The key elements of the Company's strategy are to:
 
    Increase Penetration of RMP. Through the development of RMP, the Company has
targeted a substantially broader market opportunity. RMP focuses on the
management of utilization and quality of client networks without accepting
capitation risk. As a result, the Company is not restricted by insurance
licensing requirements in connection with the provision of RMP and is able to
pursue contracts to provide RMP to payors, other than HMOs. In addition, the
Company believes that payors are receptive to RMP as it allows them to maintain
established payment relationships and associated claims processing and payment
with their provider networks. The Company is aggressively marketing RMP to a
wide variety of payors, including managed care organizations, traditional
indemnity plans, PPOs and self-funded employers, which the Company believes
represented an additional market of approximately $26.6 billion in radiology
health care costs in 1994. At March 31, 1996, the Company had implemented three
RMP contracts covering approximately 1.2 million lives.
 
    Expand CDIP. The Company believes a significant opportunity exists for
capitated arrangements and will continue to aggressively market CDIP, targeting
those payors that seek to control costs and manage utilization through
capitation for large membership populations. The Company believes there is a
trend among HMOs to outsource management of diagnostic imaging services on a
capitated basis to fix their costs and reduce the internal burden of cost
management for these services. The limited penetration of capitated arrangements
in diagnostic imaging managed care to date will, in the Company's view, provide
the opportunity for increased implementation of CDIP. As of January 1, 1995,
total enrollment in HMOs is estimated to have been over 50 million lives. At
March 31, 1996, the Company had implemented 13 CDIP contracts covering
approximately 1.4 million lives.
 
    Leverage Existing Client Relationships. The Company's existing client base
provides a significant opportunity for additional RMP and CDIP contracts. For
example, the Company believes it can expand geographic coverage by building on
existing contracts with national and regional payors. As RMP and CDIP are
marketed to local and regional health plan executives, the Company's expertise
and reputation will enable it to pursue arrangements with other local plans of
geographically diverse payors or with such payors on a regional or national
basis. In addition, the Company intends to expand its product offerings by
contracting with clients for additional member segments, such as commercial
Medicare and Medicaid plans. In the event the Company enters into arrangements
involving Medicare or Medicaid, certain provisions of federal law with respect
to referrals will become applicable to the Company's business activities. See
"--Regulation--Federal Regulation."
 
    UtiliMed believes this strategy will enable it to remain the leading
provider of physician network management services in the diagnostic imaging
sector because of the advantages it offers to both providers and payors. Rather
than seeking to generate savings through discounted fees, the Company focuses on
utilization management, quality management, the education of physicians
regarding cost-effective protocols and the precertification of costly
procedures. The Company's products encourage consultation between the
radiologist and the referring physician in the clinical decision-making process
 
                                       30
<PAGE>
to reduce unnecessary utilization and ensure that the most appropriate
procedures are performed to meet the needs of the patient. By building
relationships with and providing educational resources to network physicians,
the Company seeks to ensure that its clients obtain efficient and cost-effective
diagnostic imaging services.
 
COMPANY PRODUCTS
    CDIP AND RMP
    The Company offers two products to payors, CDIP, its capitated product,
through which the Company manages provider networks and accepts capitation risk,
and RMP, its fee-based product, through which the Company provides network
management services to control costs and enhance the quality and service
rendered by providers. CDIP and RMP, which share certain core elements, are both
designed to reduce excess utilization of diagnostic imaging and to improve the
quality of care for those patients who require diagnostic imaging services in an
effort to reduce costs. Under both CDIP and RMP, the Company receives a pmpm
payment from clients. The pmpm payment under CDIP is larger because the Company
is compensated for assuming the financial risk for variations in utilization
levels and associated medical costs, while under RMP the Company does not alter
the pre-existing payment relationship between the client and its providers.
 
    Under CDIP, the Company receives a fixed pmpm payment from its client. The
Company, in turn, negotiates with providers to arrange for the provision of
diagnostic imaging services to the client's membership population. For each CDIP
client, the Company negotiates agreements with (i) individual providers or (ii)
a group of providers who are linked through certain contractual arrangements, in
the region served by the client and arrange payment structures with such
providers and provider networks. Depending upon the specific physician practices
and clinical entities involved, the Company uses variations of four provider
payment methods in its CDIP networks to manage capitation risk and appropriately
incentivize physicians to provide efficient utilization and quality care:
capitation, fee-for-service, fee-per-visit and episode-of-care. Under the
capitation method, providers receive a pmpm payment from the Company related to
the number of members under that provider's care. In the fee-for-service method,
providers receive a fee for each diagnostic imaging service rendered to a
member. In contrast, when the Company pays a provider through a fee-per-visit
method, the provider receives a fee for a member's visit, which may or may not
include the provision of diagnostic imaging services. The episode-of-care method
combines incentives to perform the most appropriate tests, while taking into
account the possibility of wide variations in the services required by
individual members. Under the episode-of-care methodology, the Company sets
aside a pool of funds each month based upon the capitation rate. Monthly
payments to the providers or distributions from the pool are based on the number
of appropriate and necessary procedures performed by the provider each month.
Such payments are modified according to the complexity of the diagnostic imaging
services performed in order to account for differences in patient illness
severity. In general, the Company employs capitation and episode-of-care payment
arrangements for payments to radiologists and for the use of their associated
diagnostic imaging facilities, and fee-for-service and fee-per-visit for
non-radiologists, such as podiatrists, orthopedic specialists and urologists. In
the event a client realizes significant savings in diagnostic imaging
expenditures under certain CDIP contracts, the client may receive a portion of
the pool of funds established by the Company to fund provider payments.
 
    Under RMP, the Company also receives a pmpm fee, but payments to providers
continue to be made directly by the clients. The Company works with RMP clients
to manage the quality and utilization of existing provider networks, but does
not organize or establish networks of providers. The Company and its RMP clients
agree upon annual utilization cost reductions to be realized by the client
following adoption by the client of certain operational changes and
implementation of RMP. In two of the three RMP contracts, the Company will
receive additional revenue if the client realizes cost savings that exceed the
specified levels for utilization cost reductions. In one contract, a portion of,
and in another contract, up to all of the total fees received by the Company
under such agreements are
 
                                       31
<PAGE>
dependent upon the realization by the client of the specified savings levels.
See "--Clients; Capitation Contracts and Provider Contracts; RMP Contracts."
 
    CORE PRODUCT ELEMENTS
    The following chart describes the product elements of CDIP and RMP:

</TABLE>
 
    The core product elements shared by CDIP and RMP are:
 
    Assessment. The Company provides a systematic review of the facility or
office of each provider affiliated with a client, assessing the integrity of the
provider's equipment, the quality and training of its personnel, and its
policies and procedures pertaining to quality and patient safety. The standards
for the Company's assessment are developed from the Company's own expertise, the
Occupational Health and Safety Act and applicable state guidelines, and are
finalized in consultation with the Company's clients. The Company's assessment
database enables it to identify imaging sites that do not conform to the quality
and safety standards determined by the Company through its analysis of
assessment data and in consultation with its client.
 
    Privileging. The Company uses its expertise in diagnostic imaging service
management to recommend to its clients that certain procedures be performed by
specific participating network providers, such as primary care physicians and
specialists. These recommendations are based on physician specialty and patient
needs. Using the Company's recommendations, a participating client determines
the final privileging decisions based on the incentives best suited for its
health plan.
 
    Precertification. Precertification is a process whereby referring physicians
are required to certify diagnostic imaging procedures with UtiliMed before they
are performed by providers. The Company's precertification process aims to
maintain or enhance the quality of care while reducing overutilization of
diagnostic imaging services. UtiliMed emphasizes precertification for more
expensive procedures such as MRI, CT and nuclear medicine, which according to
UtiliMed's data, account for approximately 11% of the volume of diagnostic
imaging performed but approximately 50% of the cost of diagnostic imaging.
 
    By using the Company's precertification process, providers can be
compensated solely for procedures that are medically necessary. For
participating clients, the Company's precertification service works together
with the Company's assessment and privileging services to enhance the cost
efficiency and the appropriate use of diagnostic imaging. The Company provides a
toll free number for referring physicians affiliated with its clients to
precertify certain diagnostic imaging exams. In general, when it is determined
by a referring physician that a patient may need to undergo a diagnostic imaging
procedure, the physician calls the toll free number and is connected with a
trained referral associate. Using the Company's database and information
concerning the specific plan and membership, the referral associate may approve
the procedure. If the referral associate is unable to certify the procedure,
then the request is referred to a nurse, who is permitted to exercise more
discretion in providing precertification. If the nurse cannot approve the
proposed procedure, then the request must be referred to one of the
 
                                       32
<PAGE>
Company's five medical directors (or, under one RMP contract, the physician who
is to perform the exam) to discuss the decision to approve or deny the
precertification request with the referring physician. Each of the Company's
medical directors is a licensed physician. Only a qualified physician may deny a
precertification request. A denial by a Company medical director (or, under one
RMP contract, the physician who is to perform the exam) may be appealed by the
referring physician to the client health plan.
 
    Retrospective Utilization Reporting. The Company maintains an extensive
database of both clinical information and claims data. The Company collects
clinical information from reports made by imaging providers whenever diagnostic
imaging services are rendered. Claims data is collected from clients and
potential clients in the process of assessing utilization levels and in the
Company's determination of appropriate product pricing. See "--Regulation--State
Regulation--Private Utilization Review Agent."
 
    Using the information in its database, the Company produces a series of
utilization management reports in which the Company analyzes (i) the diagnostic
imaging services that referring physicians order and the frequency with which
particular services are ordered and (ii) the practice patterns of providers.
These reports are distributed to clients as well as individual providers and
referring physicians. The Company focuses its utilization management reporting
and analysis on optimizing the use of diagnostic imaging procedures by allowing
clients to evaluate affiliated providers and enabling such providers to
benchmark themselves against their peer physicians. Utilization management
reports include the following:
 
 . Quarterly Client Reports;
 
 . Quarterly Radiologist Reports;
 
 . Semi-annual Referring Physician Reports;
 
 . Semi-annual In-office Provider Reports; and
 
 . Specialty Reports, with respect to specific symptom complexes or disease
entities.
 
    Physician Education. The Company uses its expertise in diagnostic imaging
and information derived from its database to educate physicians affiliated with
its clients concerning developments in diagnostic imaging and procedures that
enhance the efficient delivery of diagnostic imaging services. For each client
with which the Company contracts, the Company can establish Local Imaging
Advisory Councils (the "Councils") comprised of Company staff, employees of the
participating clients and physicians located in the contract area. Of its 16
contracts at March 31, 1996, the Company established Councils for eight of the
last nine contracts.
 
    The Company uses its database to provide physician-specific education and
diagnosis-specific information, allowing clients and the Councils to work with
particular physicians to refine their diagnostic imaging procedures and also to
work with all physicians with whom the clients are affiliated to ensure that
particular procedures are utilized in cost-effective and appropriate ways. To
this end, the Company, after consultations with its clients and the Councils,
assembles educational materials with respect to common clinical indications,
which materials are delivered to specific referring physicians within a given
client's network. Each set of materials typically includes a report describing
the clinical entity and appropriate practice patterns, care algorithms and
relevant medical literature. The Company makes available to the referring
physician a toll free number to provide feedback to the Company following
receipt of the materials. The Company typically undertakes an analysis of the
referring physician's practice pattern approximately six months after delivery
of the materials. This subsequent analysis is provided to the relevant client
and Council.
 
                                       33
<PAGE>
INFORMATION SYSTEMS
 
    The Company makes use of a database consisting of three integrated
components claims information covering radiology services performed on over
eight million lives since 1991; assessment data recorded since 1993 on over
10,000 imaging sites in the United States; and clinical data from over one
million imaging exams collected since 1992. The number of monthly clinical
reports added to the database has grown from approximately 35,000 in March 1995
to approximately 54,000 in March 1996. These components interact to provide the
Company with detailed information on the reasons for ordering imaging exams, the
clinical results of such exams, the demographics of the populations involved and
the quality of the delivery sites and examinations actually performed. The
Company collects data through the performance of core elements of each program
and interactions with potential clients. This process results in the
accumulation and updating of information. A portion of the net proceeds of this
offering will be used to upgrade the UtiliMed computer system from a limited
file server environment to an integrated server Unix platform environment
through the purchase of systems hardware and software. See "Use of Proceeds" and
"Management's Discussion and Analysis of Results of Operations--Liquidity and
Capital Resources."
 
    Access to the database is limited to certain employees of the Company. The
data is backed up daily, with a full copy kept off-site in a secure location.
 
CLIENTS; CAPITATION CONTRACTS AND PROVIDER CONTRACTS; RMP CONTRACTS
 
    At March 31, 1996, the Company had agreements with 16 clients, comprised of
13 CDIP contracts and three RMP contracts. Fees earned pursuant to contracts
with ChoiceCare Health Plans, Inc., United HealthCare of Ohio, Inc.--Western
Region and CIGNA HealthCare of Northern New Jersey, Inc. accounted for
approximately 20.2%, 14.1% and 13.7%, respectively, of the Company's total
revenues in 1995, and approximately 20.0%, 14.6% and 16.0%, respectively, of the
Company's total revenues for the first quarter of 1996. Similarly, although the
Company's contracts with affiliates of CIGNA are independently negotiated and
operated, the Company had five such contracts in 1995 that represented, in the
aggregate, approximately 29.3% of total revenues for the year ended December 31,
1995 and, with the commencement of a sixth contract with a CIGNA affiliated
client in 1996, such contracts represented, in the aggregate, 40.7% of the
Company's total revenues for the first quarter of 1996. The Company expects that
a majority of its revenues will continue to be attributable to a limited number
of clients.
 
    During the second half of 1996, the Company entered into discussions with a
client with respect to the renegotiation of a CDIP contract. Although willing to
consider proposed contract modifications, the client first required assurances
with respect to the Company's working capital position because of the Company's
financial condition at that time. On March 12, 1996, the Company and the client
executed a letter agreement (the "Letter Agreement"), requiring the Company to
deposit $6,200,000 with the client (the "Deposit"), which amount represented the
estimated amount of the payables to providers affiliated with the client. The
amount of the Deposit is subject to quarterly adjustment. At March 31, 1996, the
amount of the Deposit was adjusted by the Company to $5.6 million. The client is
required to return the Deposit when the Company's ratio of cash equivalents to
current liabilities has exceeded 1:1 for two consecutive fiscal quarters.
Following execution of the Letter Agreement, the Company and the client reached
a business agreement with respect to the renegotiation of the CDIP contract,
subject to completion of documentation. Until the return of the Deposit to the
Company, the Company is a general creditor of the client for the amount of the
Deposit. The Letter Agreement provides for the client to be paid interest on the
Deposit at short-term rates.
 
    CDIP CONTRACTS
 
    A CDIP contract is tailored to the particular structure and needs of a
specific client. Under these contracts, the Company arranges for providers to
render services to participating clients and their members, and maintains
networks to ensure that physicians provide timely service to client members. In
 
                                       34
<PAGE>
these contracts, UtiliMed warrants the due licensing and certification of the
physicians, and the client may cause the Company to exclude providers from a
given network or terminate agreements with such providers. The client pays the
Company on a capitated basis pursuant to a schedule agreed upon by UtiliMed and
the client, which normally allows for annual changes based upon changes in the
CPI. Payments to providers are the sole responsibility of UtiliMed, except for
services not covered by the patient's benefit contract, co-payments or
deductibles. Neither the Company nor the providers has any right to payment from
the client for services rendered by the providers, other than the Company's
right to receive its pmpm. The CDIP contracts require UtiliMed to maintain
liability insurance, and the physician providers with which the Company
contracts, to maintain malpractice insurance. UtiliMed is required to keep
confidential information gained from clients and network physicians under CDIP.
CDIP contracts have an initial term of one to five years, with automatic renewal
for terms of one to five years. CDIP contracts can generally be terminated by
either the Company or the client upon a material breach and notice, after giving
the breaching party a period to cure. Several of the CDIP contracts may be
assigned by the client without UtiliMed's consent.
 
    PROVIDER CONTRACTS
 
    For CDIP, UtiliMed also enters into contracts with networks established by
the Company that are comprised of (i) individual providers or (ii) groups of
providers who are linked through certain contractual arrangements, to arrange
for the delivery of services to the members of client plans. Under these
contracts, providers perform and interpret diagnostic imaging tests in
consultation with the referring physicians of the client and are generally
obligated to make reasonable efforts to respond within 24 hours of a referral
request and deliver to the referring physician all preliminary reports within 24
hours of the examination. Providers warrant to UtiliMed that they hold all
licenses necessary for the provision of services for the term of the provider
contract. UtiliMed may terminate the contract or exclude the services of a
provider or any employee of a provider in the event of a revocation or
suspension of licenses or any disciplinary action taken against such persons.
The provider contracts generally provide that all patient files, examination
reports and images be made available to the Company on request, which
information is kept confidential by UtiliMed. The provider is paid by the
Company pursuant to one of the four primary payment methods employed by the
Company to incentivize such physicians. See "--Company Products--CDIP and RMP."
Under these contracts, physicians agree that in no event shall they have any
recourse against the client, members of the client plan or persons other than
the Company for services provided. However, the physician is generally permitted
to collect co-payments in accordance with the client's agreement with its plan
members, or for services not covered under the provider contract. In the first
quarter of 1996, the Company began to require submission by providers of all
claims for payment within 90 days of rendering services as a prerequisite to
receiving payment. As the Company's existing provider contracts are renewed or
the Company enters into new provider contracts, the Company intends to implement
similar provisions in such contracts. Under the provider contracts, physicians
are required to maintain malpractice insurance and submit proof of such
insurance to the Company prior to the delivery of services. Provider contracts
generally have a one year term, which is automatically renewable for additional
one year terms. If a provider ceases to participate in a particular client plan
subject to a CDIP contract, then the related provider agreement may be
terminated at the Company's discretion.
 
    RMP CONTRACTS
 
    Under RMP, the Company agrees to provide management services to a client's
existing provider network. The Company and the client determine RMP
pre-implementation baselines for utilization costs, and mutually agree on
specified savings levels with respect to such utilization costs over the term of
the contract. The pmpm fee is paid at a flat monthly rate, with provision for
settlement after more extended periods (annually or at the end of term) that
varies from contract to contract. In two of the three RMP contracts, the Company
will receive additional revenue if the client realizes cost savings that exceed
the specified levels for utilization cost reductions. In one contract, a portion
of, and in another contract, up to all of the total fees received by the Company
are dependent upon the realization by the client of the specified savings
levels. Under RMP, the Company is obligated to maintain professional
 
                                       35
<PAGE>
liability insurance. RMP contracts generally have an initial term of up to five
years, allowing for renewal.
 
SALES AND MARKETING
 
    The Company seeks to contract with large, sophisticated health care payors,
such as HMOs, PPOs, managed indemnity organizations and other health care payors
with enrollments in excess of 100,000 members. The Company markets directly to
key decision makers of both existing and potential clients. UtiliMed has begun
marketing its products to consulting organizations and large national employers,
which bring the Company and its products to the attention of benefits
administrators and managed care companies. As relationships are established,
UtiliMed typically obtains data enabling it to assess the product and pricing
that is most suitable for the payor, and demonstrate the value of the services
the Company offers. The Company and its personnel also participate in national
and regional health care conferences, which the Company considers a valuable way
to describe UtiliMed's products to the managed care market. The Company
continues to develop additional business by building upon existing client
relationships within national health care organizations, including United
HealthCare, Inc., CIGNA and Blue Cross Blue Shield plans, and marketing to
regional health care payors.

<PAGE>
COMPETITION
 
    The Company faces current and potential competition from a number of diverse
sources and in differing degrees with respect to its two products. For CDIP,
certain health care providers have organized themselves into capitated networks,
while other companies have specialized in the capitation of radiology networks
on a more limited scale than the Company. In addition, certain companies have
established capitation programs with respect to disciplines outside of
radiology, which companies could expand the scope of services offered to include
diagnostic imaging. Finally, certain health care payors have chosen to establish
capitation programs on their own. For RMP, certain companies are attempting to
offer some of the same services as the Company in more limited geographical
areas, or with respect to certain components of the Company's business,
particularly for certification and utilization review. In addition, payors may
choose to reduce diagnostic imaging costs through the internal development of
aspects of the products offered by the Company. Other companies offer
utilization review of data analysis and reporting services (two of the Company's
core product elements) with respect to other health care specialties and
services. The Company competes on the basis of its specialized knowledge and
expertise in diagnostic imaging managed care, the effectiveness of its services,
its ability to offer a range of services in multiple markets, its database
management capability and pricing.
 
REGULATION
 
    GENERAL
 
    The Company's business is conducted within a highly regulated environment.
There are both state and federal regulatory programs relating to the provision
of health care services, access to health care, the cost of health care and the
manner in which health care providers are reimbursed for their services. The
state and federal health care and insurance laws and regulations to which the
Company may be subject in connection with its operations are summarized below.
As described herein, the regulatory obligations associated with the Company's
CDIP product are more extensive than under the RMP product. The Company believes
that it is in compliance with all regulatory requirements applicable to its
business.
 
    STATE REGULATION
 
    The Company's activities are regulated principally at the state level, so
that the Company must comply with regulatory requirements that vary from state
to state. The Company currently offers its CDIP and RMP products in the states
of Colorado, Connecticut, Florida, Illinois, Indiana, Kentucky, Missouri, New
Jersey, New York, Ohio and Oklahoma. In the states of Massachusetts and

    Insurance Regulation. There are significant state law obstacles to third
party payors sharing risk through capitation with provider networks like those
that the Company organizes in connection with its CDIP program. The evaluation
of the regulatory obligations imposed upon provider networks which assume risk
must be conducted on a state-by-state basis as the positions taken on this
subject by state regulators are not uniform. In most states, insurance risk is
regulated primarily through two distinct insurance statutes: the state insurance
code (as a health insurer) and the state health maintenance organization act.
Under each of these types of statutes, any person who engages in the business of
insurance risk on an indemnified or prepaid basis must typically secure a
certificate of authority from the state department of insurance ("DOI"). These
statutory provisions could be interpreted such that contractual arrangements for
the sharing of risk among providers could be deemed by the state DOI as
constituting a contract of insurance which may be issued only by a
state-licensed insurance company or HMO.
 
    On August 10, 1995, a working group of the National Association of Insurance
Commissioners ("NAIC") issued to state insurance commissioners a suggested
insurance bulletin which addressed the state regulation of risk-bearing provider
networks. Provider networks were described as groups of health care providers,
including integrated provider organizations, integrated provider arrangements,
physician hospital organizations and provider sponsored networks. The working
group's recommendations permitted provider networks to accept risk from licensed
insurance entities. The acceptance of risk
 
                                       37
<PAGE>
directly from employers or individuals, however, would require the provider
network to obtain some form of insurance license. The actions of the NAIC are
not binding upon state insurance commissioners, but, historically, the
regulatory positions taken by the NAIC have been adopted in many states.
 
    In the states in which the Company currently operates, state insurance
regulators have permitted HMOs to contract with provider networks on a capitated
basis. The rationale for this conclusion varies from state to state. Some states
view capitation arrangements between HMOs and provider networks as acceptable
without further licensure on the grounds that the HMO is properly structured to
monitor and oversee such arrangements and would ultimately be liable for any
losses. This is similar to traditional treatment of HMO contracts with physician
individual practice associations ("IPAs"). In other states, state insurance
regulators have concluded that the HMO licensure statute expressly authorizes
HMOs to enter into risk sharing arrangements with groups of providers. In still
other states, insurance regulators have concluded that HMO licensure is not
appropriate because provider networks do not market directly to the public, but
serve merely as subcontractors of health care services that comply with the
policies and procedures established by the HMO.
 
    The ability of traditional indemnity insurers and self-insured employers to
share risk with groups of providers is more constrained. Consequently, the
Company only offers the CDIP product to HMOs, and not other types of payors. In
addition, the Company has established two wholly-owned subsidiaries which
operate in the state of New York and which are certified as IPAs under special
regulations governing provider risk sharing arrangements with HMOs.
 
    In most states, HMOs are permitted by statute to capitate individual
providers or professional corporations established by providers. However, the
capitation of provider networks in which payors shift risk to organizations
providing healthcare services by unrelated providers may be interpreted in some
states as constituting the unlicensed business of insurance. Many states,
including states where the Company does business, currently are reviewing their
position on the issues described above relating to HMOs and insurance licensure.
 
    The Company believes that in the states where it currently operates, HMOs
can enter into capitation arrangements with provider networks without the
possibility that the associated compensation mechanisms will require the Company
to obtain an insurance license. The Company believes that its participation in a
capitated provider network does not require insurance licensure.
 
    Preferred Provider Organizations. Although the definition of a PPO may vary
from state to state, a PPO is generally a legal entity which has established a
provider network by entering into contractual arrangements with a variety of
health care providers. PPOs can also be established via a contractual
relationship among providers. The PPO, in turn, contracts with HMOs, health
insurers or self-insured employers to arrange for the provision of health care
services through the PPO's provider network. PPOs are typically organized under
state law as for-profit or not-for-profit corporations.
 
    In states which have enacted a PPO law, the establishment of a provider
network under CDIP may subject the Company to compliance with the PPO law. The
Company's RMP product is unaffected by PPO laws. Generally, state PPO laws are
not onerous. Such laws usually require the submission to regulators of provider
contracts and guarantees of patient accessibility to providers in a geographic
area. In some states which regulate PPOs sponsored by insurance companies, the
PPO laws (and in some states, HMO laws) include an "any willing provider"
provision, which requires the PPO (or HMO) to include any provider in the panel
who is willing to accept the financial terms offered to the panel provider.
However, the independent provider networks in which the Company participates are
not usually subject to these "any willing provider" requirements.
 
    The Company believes it has complied with all PPO laws which are applicable
to its operations.
 
    Third Party Administrator. A TPA is an organization that provides
administrative services, such as claims adjustment, case management and premium
collection, that are normally provided by an insurer. When a TPA that is not an
insurer provides these services to group benefit plans and the self-insured,
they are often regulated by the state. States require that the TPA act in a
fiduciary capacity, maintain financial reserves and keep records confidential.
Moreover, many states prohibit a TPA from
 
                                       38
<PAGE>
being compensated on the basis of claims experience. As such regulations are
currently interpreted in the states where the Company presently operates or
intends in the near term to operate, the Company believes it is not subject to
regulation as a TPA because the Company is not engaged in providing any of the
administrative services described above pursuant to either RMP or CDIP. In the
event the Company provides services in states where it would be subject to
regulation as a TPA, the Company intends to comply with such regulations.
 
    Private Utilization Review Agent. Provider network organizations that
perform prospective, concurrent or retrospective review of the health care
services provided through a provider network may be subject to state licensure
as "private utilization review agents." Typically, licensure as a private
utilization review agent requires the submission of an application to the state
and prior approval before performing utilization review services ("UR Services")
on residents of the state. The application typically requires the submission of
information about the types of personnel performing UR Services, policies on
confidentiality of medical records, access (5 or 7 days a week, business hours
or 24 hours, or a toll-free telephone number) and appeals procedures. In
addition, some states require the submission of the actual criteria used in
conducting UR Services; other states may only request a copy of the process by
which the criteria were developed.
 
    Potential limitations on the types of personnel who may perform UR Services
are emerging as an important regulatory concern for private utilization review
agents. For instance, some states mandate that only physicians and not nurses or
therapists may render denials to certification of health care service proposed
to be rendered by physicians. In addition, some states require that any denial
be made or any appeal be conducted only by a physician with board certification
in the same specialty as the physician requesting the health care services that
is the subject of the review. For example, in the Company's case, a radiologist
would be required to conduct appeals from denials of requests by radiologists.
Although the Company does (i) precertify the use of certain diagnostic imaging
techniques and (ii) perform certain retrospective utilization reviews under both
CDIP and RMP, these activities have generally not implicated the private
utilization review statutes of the states in which the Company operates; in
those states where such statutes are applicable to the Company's activities, the
Company has pending applications for licensure.
 
    Corporate Practice of Medicine and Fee Splitting. In some states, physician
licensure provisions are construed to prohibit physicians from practicing
medicine through business corporations. This prohibition, known as the
"corporate practice of medicine" doctrine is sometimes expressly stated in the
state's medical practice act and corresponding regulations. In other states, the
corporate practice of medicine doctrine exists only as a product of the
development of common law. The corporate practice of medicine doctrine is
generally grounded upon concerns over the ability of a physician to exercise his
or her independent medical judgment and to preserve doctor-patient
confidentiality when non-physicians have a pecuniary interest in the physician's
practice. The corporate practice of medicine doctrine is usually used to prevent
the employment of physicians by a corporation other than a professional
corporation. Contractual relationships, depending upon the level of control
exerted over the physician through the contract and the level of enforcement of
the doctrine in the state, may trigger corporate practice concerns. Many states
provide for the suspension or revocation of a physician's license if the
physician enters into fee-splitting or referral arrangements with a third party.
An arrangement in which a provider network receives a capitation payment from an
HMO or from the Company pursuant to the CDIP program for health care services
provided by the participating physician's of such network could be perceived as
a split-fee arrangement. However, no state in which the Company currently
operates has adopted this position with regard to participation in a capitated
provider network.
 
    The Company believes that its contractual relationships with providers
pursuant under CDIP are not violative of the "corporate practice of medicine" or
"fee splitting" prohibitions. These regulatory prohibitions are not applicable
in the context of RMP.
 
    Self-Referral. Many states have adopted their own versions of the federal
physician self-referral statute described below which apply to all patients
irrespective of whether payment for health care services is provided by the
Medicare or Medicaid programs. In such states, physicians are prohibited
 
                                       39
<PAGE>
from referring patients to certain health care services in which they have a
financial relationship. In those states that have enacted physician
self-referral prohibitions, an applicable statutory exception may permit certain
financial relationships with physicians. Alternatively, in other states the
physician's referral is not prohibited; provided, however, the physician must
provide the patient with a written disclosure that specifies the physician's
financial relationship or investment interest in an entity in which he or she
refers patients.
 
    Anti-kickback. Many states have promulgated anti-kickback provisions similar
to the federal anti-kickback statute described below, that broadly prohibit the
offer, payment, solicitation or remuneration to a physician in return for
referring patients. Moreover, in some states, these kickback provisions apply to
all health care payors, not merely the Medicare or Medicaid programs. Further,
while some states provide certain exceptions to the anti-kickback statutes
similar to the safe harbor regulations promulgated pursuant to the federal
anti-kickback law, other states do not incorporate the federal safe harbor
regulations nor do these states provide similar guidance.
 
    The Company believes the financial relationships between the Company and its
providers through the CDIP product are not violative of applicable state self
referral or anti-kickback laws.
 
    FEDERAL REGULATION
 
    The Company does not presently contract directly with the Medicare or
Medicaid programs. However, some of the entities with which the Company
contracts do provide services to beneficiaries of the Medicare and Medicaid
programs. Set forth below is a description of the federal laws and regulations
to which the Company may be subject through its contracts with clients providing
services to Medicare and Medicaid beneficiaries. See "--Strategy."
 
    Medicare Fraud and Abuse Provisions. The Medicare and Medicaid anti-kickback
amendments (the "Anti-Kickback Amendments") prohibit the knowing and willful
offer, payment, solicitation or receipt of any form of remuneration in return
for the referral of Medicare or state health program patients or patient care
opportunities, or in return for the purchase, lease or order of any item or
service that is covered by Medicare or a state health program. In addition to
federal criminal penalties, the Anti-Kickback Amendments also establish the
intermediate sanction of excluding violators from participation in the Medicare
or Medicaid programs.
 
    Pursuant to this law and in an effort to reduce potential fraud and abuse
relating to Medicare costs, the federal government has announced a policy of
increased scrutiny of various transactions among health care providers.
Nevertheless, the applicability of these provisions to many business practices
in the health care industry, including the Company's agreements with physician
groups and its agreements with HMOs, has not been subject to any enforcement
actions or judicial interpretation. In 1991, the Inspector General of HHS
adopted regulations defining safe harbors for certain arrangements that do not
violate the Anti-Kickback Amendments. On January 25, 1996, the HHS Office of
Inspector General issued the final managed care safe harbor regulations defining
certain managed care relationships that will not constitute a violation of the
anti-kickback amendments. The safe harbors address provider discounts to health
plans, incentives offered to enrollees to choose network providers, as well as
certain waivers of coinsurance amounts in connection with Medicare SELECT
policies. The safe harbors do not provide explicit protection for financial
arrangements engaged in by intermediary managed care organizations such as the
Company. However, the preamble to the safe harbors does address such financial
relationships with intermediary organizations in the context of fees charged to
participating providers. In addressing such relationships with providers, the
preamble states that PPOs can cover their marketing and administrative costs "in
fees charged to insurers or employers where the PPO administers the plan for
such entities", implying that such arrangements would not implicate the
anti-kickback statute in the first instance. The Company therefore believes that
the management fees payable to it by payors should not be viewed as remuneration
for referring or influencing referrals of Medicare or state health care program
patients as prohibited by the Anti-Kickback Amendments, as the Company is not
referring any patients to the payor which is paying the Company the management
fees. Rather, the only referrals the Company could be viewed as potentially
making is the referral of patients to its network providers.
 
                                       40
<PAGE>
    In any event, the safe harbor regulations are clear that failure to conform
to the terms of a particular safe harbor does not mean that the arrangement is
illegal. The preamble also states that compliance with the safe harbor
regulations is "purely voluntary."
 
    The Company receives compensation under its CDIP and RMP agreements with
payors for management services. The Company believes that the management fees
payable to it should not be viewed as remuneration for referring or influencing
referrals of patients or services covered by such programs as prohibited by the
Anti-Kickback Amendments as the Company is not referring patients to the payor
which is paying the Company the management fees. The Company is not presently a
provider or supplier of services or items reimbursed by Medicare or state health
programs.
 
    Prohibitions on Certain Referrals--The "Stark Law". The Omnibus Budget
Reconciliation Act of 1993 ("OBRA") includes a provision that significantly
expanded the scope of the Ethics in Patient Referral Act, also known as the
"Stark Law." The Stark Law originally prohibited a physician from referring a
Medicare or Medicaid patient to any entity for the provision of clinical
laboratory services if the physician or a family member of the physician had an
ownership interest or compensation relationship with the entity. The revisions
to the Stark Law included in OBRA prohibit a physician from referring Medicare
and Medicaid patients to an entity in which the physician or a family member has
an ownership interest or compensation relationship if the referral is for any of
a list of "designated health services." The list of designated health services
includes radiology services and radiation therapy. Under CDIP, the Company does
not currently contract with providers of therapeutic radiation services, only
diagnostic radiology services. As the Company is not owned by physicians, the
only financial relationship potentially relevant to the Stark Law between the
Company and its network physicians is the physicians' provider agreement. While
this agreement does constitute a financial relationship within the meaning of
the Stark Law, such a financial relationship only means that the physician
cannot refer Medicare and Medicaid patients to the Company for the furnishing of
designated health services, including radiology services. However, the Company
does not furnish designated health services; the Company merely contracts for
the provision of designated health services. Accordingly, the Company believes
that its contractual relationships with physicians do not implicate the Stark
Law. The Health Care Financing Administration has issued final regulations
regarding the Stark I clinical laboratory self-referral ban, but no final
regulations have yet been issued regarding the application of the Stark Law to
designated health services. The preamble to the Stark I regulations address
generally the issue of indirect financial relationships in the form of
compensation arrangements, but the regulations do not expressly address this
issue. In the event the Stark II regulations take the position that the
Company's contractual arrangements for the provision of radiology services do
implicate the Stark Law, then the Stark Law includes an exception for personal
services contracts, with which the Company should be able to conform its network
physician provider agreements.
 
    Physician Incentive Law--Managed Care Organizations. By statute, HMOs and
competitive medical plans ("CMPs") which have a risk-sharing agreement with the
Medicare program and certain HMOs and health insuring organizations ("HIOs")
which contract with the Medicaid program cannot operate a physician incentive
plan unless that physician incentive plan meets certain specified criteria.
Under the Medicare and Medicaid programs, there are three requirements that a
managed care organization must meet with regard to any physician incentive plan
if the managed care organization has a Medicare or Medicaid contract. First, the
plan cannot, directly or indirectly, make payments to physicians as an
inducement to limit or reduce medically necessary services provided to a
specific enrollee. Second, the plan cannot place a physician at substantial
financial risk for services the physician does not provide without adequate
stop-loss protection and periodic enrollee surveys. Third, the organization must
disclose the nature of its plan to the Secretary of HHS. Failure to comply with
these requirements could subject the organization, by statute, to sanctions and
civil monetary penalties. The Company has not entered into a risk contract with
the Medicare or Medicaid programs. To the extent the Company contracts with HMOs
that have a Medicare or Medicaid risk contract, the Company may be indirectly
affected by the physician incentive law. On March 28, 1996, the Health Care
Financing Administration issued final regulations regarding this law. The
Company believes that its capitation and episode-of-care compensation
arrangements with providers do not violate the requirements of the
 
                                       41
<PAGE>
physician incentive laws and, if necessary, can be restructured in a manner to
comply with the final physician incentive regulations. Such compensation
arrangements have been developed by the Company on the basis of the levels of
Medicare reimbursement and utilization by physicians prior to the implementation
of the Company's products. Therefore, these arrangements should not contain
improper financial incentives to reduce the utilization of health care services.
 
    REGULATORY COMPLIANCE
 
    The Company believes that health care regulations affecting the Company will
continue to change and, as a result, regularly monitors developments in health
care law. The Company believes it will be able to continue to structure all its
agreements and operations in accordance with applicable law or, if necessary,
modify its agreements and operations as regulations applicable to its business
undergo change. However, there can be no assurance that current or future
operations will not require compliance with additional governmental regulatory
schemes or be adversely affected by changes in regulatory requirements
applicable to the Company's business.
 
EMPLOYEES
 
    At March 31, 1996, the Company had 189 full-time employees, and two
part-time employees. The Company also has consulting arrangements with six
additional persons, four of whom are full-time. None of the Company's employees
is represented by a labor union or subject to a collective bargaining agreement.
The Company has never experienced a work stoppage and believes that its employee
relations are good.
 
PROPERTY
 
    The Company's principal executive offices, located at 40 Skokie Boulevard,
Northbrook, Illinois, 60062-1618 are leased. The Company occupies approximately
40,364 square feet under several leases, expiring at various times from August
31, 1996 to August 31, 1999. In addition, the Company leases storage space in
the same facility under a short term lease and is negotiating to lease
additional office space in the same facility, which it believes will be
sufficient for its operations in the future. See Note 7 to the Consolidated
Financial Statements.
 
LEGAL PROCEEDINGS
 
    No litigation is currently pending against the Company or its property, and
the Company is not aware of any outstanding claims against any participating
payors or providers, in either case, that would have a material adverse effect
on the Company's business, operating results or financial condition. The Company
expects its clients to be involved in legal proceedings incident to their
business, some of which may involve claims related to the practices of
affiliated health care providers. See "Risk Factors-- Possible Litigation and
Insurance."
 
INSURANCE
 
    The Company's agreements with clients generally require the Company to
maintain professional liability insurance in the amounts of $1 million per
occurrence and $3 million in the aggregate. However, the Company maintains at
its own expense professional liability insurance in the amounts of $10 million
per occurrence and $10 million in the aggregate. Separately, the Company
generally requires each physician with which it contracts under CDIP to maintain
professional liability insurance coverage of $1 million per occurrence and $3
million in the aggregate, except where state law allows lesser amounts.

(1) The salaries for Dr. Spiro and Messrs. Zechman and Rubinstein reflect
    short-term reductions in connection with the 1995 Transaction. The amounts
    of salaries for Dr. Spiro and Messrs. Zechman and Rubinstein will be
    increased to $200,000, $175,000 and $150,000, respectively, at such time as
    the net income of the Company is positive for any fiscal quarter. For the
    period prior to these reductions, the annual salaries for Dr. Spiro and
    Messrs. Zechman and Rubinstein were $200,000, $150,000 and $175,000,
    respectively. See "Certain Transactions--1995 Transaction."
 
(2) Dr. Adkins was awarded 245,149 restricted shares of Common Stock at $0.05
    per share pursuant to a restricted shares agreement dated as of November 17,
    1995 with the Company (and amended as of January 26, 1996). Of the
    restricted stock held by Dr. Adkins, 88,254 shares have already vested; the
    remaining 156,895 shares will vest pro rata on December 31, 1996, 1997, 1998
    and 1999, or earlier upon the occurrence of certain circumstances specified
    in Dr. Adkins' restricted shares agreement. Mr. Keller, Dr. Spiro and Mr.
    Zechman purchased 33,429, 25,995 and 109,434 restricted shares,
    respectively, of Common Stock at $0.05 per share pursuant to restricted
    shares agreements dated as of January 15, 1996, September 6, 1995 and
    September 6, 1995, respectively, with the Company. The restricted stock held
    by Mr. Keller, Dr. Spiro and Mr. Zechman will vest pro rata on December 31,
    1996, 1997, 1998, 1999, and 2000, or earlier upon the occurrence of certain
    circumstances specified in the respective restricted shares agreements.
 
(3) On September 6, 1995, the Company issued Stock Purchase Warrants to Dr.
    Adkins, Dr. Spiro, Messrs. Zechman and Rubinstein, Dr. Mintz and Ms. Lippert
    for the purchase of 33,429, 81,069, 79,842, 128,851, 184,057 and 29,250
    shares of Common Stock, respectively, which warrants become exercisable, if
    at all, on or prior to June 30, 1997 (or, under certain conditions, prior to
    September 30, 1997) if (i) the Company consummates an initial public
    offering of the Common Stock such that (a) the net cash proceeds to the
    Company from such offering exceed $30 million and (b) the price per share of
    Common Stock sold in such offering is at least $24.90 or (ii) there occurs a
    sale of the capital stock of the Company held by the Private Equity
    Investors or a merger, consolidation or other business combination, and in
    each case, (x) the Senior Subordinated Notes are repaid in full and (y) the
    Private Equity Investors receive cash proceeds (net of certain expenses and
    fees) that exceed $75 million for the Common Stock held by the Private
    Equity Investors. See "Risk Factors--Dilution" and "Certain
    Transactions--1995 Transaction." The Stock Purchase Warrants held by Drs.
    Spiro and Mintz and Mr. Rubinstein were issued in connection with the
    capital transaction portion of the 1995 Transaction and are not, therefore,
    reflected as compensation. An option was also issued to Dr. Mintz to
    purchase 4,457 shares of Common Stock in 1996 which will vest pro rata at
    August 15, 1996, 1997 and 1998.

    September 5, 1995 which provides for a base salary of $275,000 per annum.
    His salary compensation for the period from September 5, 1995 through

    above.
 
(7) Dr. Mintz served as President and Chief Executive Officer until September
    1995, and as Chairman of the Board until December 31, 1995. Dr. Mintz's
    annual salary was $350,000 until October 1, and was $250,000 for the

    Chief Financial Officer and the table reflects Ms. Lippert's salary for such
    period. See "Certain Transactions--1995 Transaction." See also footnotes 3

    an option to purchase 50,651 shares of Common Stock in April 1996 which will
    vest pro rata on January 15, 1997, 1998, 1999, 2000, and 2001.

Employment Agreement provides for Dr. Adkins to be paid a base salary of
$275,000. Under the CEO Employment Agreement, Dr. Adkins will also be paid an
annual bonus of up to 100% of the base salary if the Company achieves certain
annual performance targets to be established by the Compensation Committee of

    The CEO Employment Agreement also provides for the Company to issue 245,149
shares of Common Stock to Dr. Adkins pursuant to a restricted stock agreement
(See "--Restricted Shares Agreements"), and for the payment of certain fringe

with pay. Dr. Adkins has agreed to be bound by certain confidentiality,
non-competition and non-solicitation restrictions set forth in the CEO
Employment Agreement.
 
    OTHER EXECUTIVE EMPLOYMENT CONTRACTS
 
    The Company entered into employment contracts with Alan Spiro, M.D. and
Lawrence Rubinstein on January 1, 1994, and with James E. Zechman on June 10,
1994. Each such employment contract was amended in connection with the
Recapitalization and again in connection with the 1995 Transaction
(collectively, such employment contracts, as amended, the "Executive Employment
Contracts"). Each Executive Employment Contract provides for a term that ends on
December 31, 1996.
 
    As amended in connection with the 1995 Transaction, Dr. Spiro's Executive
Employment Contract provides for an annual salary of $160,000; Mr. Zechman's
Executive Employment Contract provides for an annual salary of $140,000; Mr.
Rubinstein's Executive Employment Contract provides for an annual salary of

the Executive Employment Contracts provide for the annual salaries of Dr. Spiro
and Messrs. Zechman and Rubinstein to be increased to $200,000, $175,000 and
$150,000, respectively.
 
    The Executive Employment Contracts provide for Dr. Spiro and Messrs. Zechman
and Rubinstein to be paid discretionary bonuses at the times and in the amounts
as are declared by the Board. Each of Dr. Spiro and Messrs. Zechman and
Rubinstein receive four weeks paid vacation.
 
    OTHER AGREEMENTS
 
    Alan P. Mintz, M.D. served as the President and Chief Executive Officer of
the Company from its incorporation until September 1995, and as Chairman of the
Board until December 31, 1995. In connection with the 1995 Transaction and the
addition of Dr. Adkins, Dr. Mintz reduced his role solely to that of Chairman of
the Board and Dr. Mintz and the Company entered into a severance agreement
effective December 31, 1995. See "Certain Transactions--1995 Transaction."
 
    Cheryl E. Lippert served as the Company's Chief Financial Officer from April
1995 to January 1996 and, following the termination of her employment, the
Company and Ms. Lippert entered into a severance agreement. See "Certain
Transactions--1995 Transaction."
 
    See Note 2 of Summary Compensation Table for a description of restricted
stock awards made to certain executive officers.
 
DIRECTORS OPTION PLAN
 
    Effective November 3, 1994, the Board and shareholders of the Company
approved the Company Stock Option Plan for Non-Employee Directors (the
"Directors Option Plan"). As amended, the Directors Option Plan provides for the
issuance of options to purchase up to 48,821 shares of Common Stock. All
non-employee directors of the Company are eligible to receive options under the
Directors Option Plan, subject to the discretion of the Compensation Committee
(as defined below). The exercise price of an option granted under the Directors
Option Plan shall be the fair market value of the Common Stock on the date of
grant and may be exercised at any time, in accordance with the individual option
agreement with the relevant non-employee director. All of the options under the
Directors Option Plan terminate on the earliest to occur of (i) ten years from
the date of the grant of the option, (ii) one year after termination of the
optionee's service with the Company due to disability, (iii) one year after the
optionee's death, if death occurs during, or within three months after, the
optionee's service with the Company, (iv) termination of the optionee's service
with the Company for cause (as defined in the Directors Option Plan), or (v)
three months after the termination of the optionee's service with the
 
                                       48
<PAGE>
Company. As of March 31, 1996, no options to purchase shares of Common Stock had
been granted under the Directors Option Plan.
 
TARSOP
 
    Effective October 28, 1994, the Board and shareholders of the Company
approved the TARSOP. As amended, the TARSOP provides for the issuance of options
to purchase up to 57,745 shares of Common Stock which either do not meet the
requirements of Section 422 of the Internal Revenue Code of 1986, as amended
("Nonqualified Options"), or options which do meet such requirements ("Incentive
Options"). All key employees and consultants of the Company are eligible to
receive options under the TARSOP. Options are granted to key employees
(including officers and directors of the Company) selected by the Compensation
Committee of the Company's Board (the "Compensation Committee") consisting of
directors who are not eligible to receive options under the TARSOP. The
Compensation Committee determines the number of shares subject to option and
whether the option is intended to be a Nonqualified Option or an Incentive
Option. The exercise price of an option may not be less than the fair market
value of the Common Stock on the date of grant. In the case of an Incentive
Option, if the grantee at the time of grant owns stock constituting 10% or more
of the total combined voting power of all classes of the Company's capital
stock, the exercise period may not extend beyond five years from the date of
grant and the option exercise price per share may not be less than 110% of the
fair market value of the Common Stock on the date of grant. Incentive Options
must also comply with the other requirements of Section 422 of the Internal
Revenue Code. None of such restrictions apply to the grant of Nonqualified
Options. All of the options under the TARSOP terminate on or shortly after
termination of the option holder's employment with the Company as described
below. As of March 31, 1996, options to purchase 57,745 shares of Common Stock
at an exercise price of $.05 per share had been granted under the TARSOP, all of
which were outstanding and no options had vested.
 
    Options granted under the TARSOP become fully exercisable no later than the
ninth anniversary of the date of grant and no option may have a term in excess
of ten years from the date of grant. The TARSOP provides for accelerated vesting
each year with respect to ten to twenty percent of the shares subject to the
option in the event certain financial tests are met, commencing with respect to
the fiscal year ended December 31, 1995. The Compensation Committee may require
all options to be terminated unless exercised within 30 days (or such longer
period as determined by the Compensation Committee), or provide that all or some
of the restrictions on options may lapse, in either case upon (i) a merger or
consolidation of the Company with another corporation such that there is a
change in the shares of the Common Stock by reason of such merger or
consolidation, (ii) a sale or conveyance of all or substantially all of the
assets of the Company, (iii) a reorganization or liquidation of the Company, or
(iv) a change in control of the Company, which includes, among other events, any
person becoming the beneficial owner of securities representing 50.0% or more of
the combined voting power of the then outstanding securities of the Company
ordinarily having the right to vote for the election of directors.
 
    Options are exercisable only while the optionee remains an employee of the
Company and terminate upon the optionee's termination of employment if the
optionee is terminated for cause. If any optionee's employment terminates
because the optionee becomes disabled or dies, such optionee's options remain
exercisable for one year after the optionee's termination of employment, unless
such options expire earlier by their own terms. If any optionee's employment is
terminated other than for cause, death or disability, such optionee's options
remain exercisable for 90 days after the optionee's termination of employment,
unless such options expire earlier by their terms. Options that are exercisable
following termination of employment are exercisable only to the extent that the
optionee was entitled to exercise such options on the date of such termination.
All options are non-transferable other than by will or the laws of descent and
distribution.

                              CERTAIN TRANSACTIONS
 
RECAPITALIZATION
 
    In November 1994, the Company entered into the Recapitalization whereby it
redeemed outstanding shares of capital stock from then existing management and
financed the transaction by issuing new capital stock and debt to the Private
Equity Investors in order to provide liquidity to the Company's founders and
senior management. By aligning the Company's organizational and capital
structure with professional investors, the Company believed the Recapitalization
would also allow the Company (i) to attract experienced and qualified directors,
such as Dr. Blutt, Mr. Castleman, Mr. Steinman and Dr. Jay who, based on their
prior business or related experience, could assist management with operational
issues as well as the strategic direction of the Company, (ii) to access the
financial and managerial advice and experience of CCP and Whitney, private
investment firms which have each invested in other similarly situated companies;
and (iii) to facilitate capital investment by other professional investors that
would not ordinarily invest in a closely-held company. See "Use of Proceeds."
 
    In the Recapitalization, the Company redeemed an aggregate of 56% of the
then outstanding shares of Common Stock from Alan P. Mintz, M.D., John E. Adams,
Lawrence Rubinstein, Nancie Blatt, Alan H. Spiro, M.D. and Sheldon K. Gulinson
(together, the "Redeemed Holders") for a total consideration of $39,874,059. The
consideration consisted of cash and an aggregate of $10,574,059 of Junior
Subordinated Notes due November 3, 2002 bearing interest at 10.0% per annum,
issued to each of the following in the specified principal amounts: Dr. Mintz,
$5,000,000; Mr. Adams, $2,500,000; Dr. Spiro, $574,059; and Mr. Rubinstein,
$2,500,000. In connection with the 1995 Transaction, the holders of the Junior
Subordinated Notes irrevocably waived the right to receive any and all accrued
but unpaid interest thereon and agreed that no further interest would accrue. On
May 24, 1996 the Junior Subordinated Notes were converted into 94,039 shares of
Common Stock in accordance with their terms.
 
    To finance the redemptions and related expenses of the Recapitalization, the
Company issued (i) 22,969 shares of Common Stock at $7.22 per share, 427,328
shares of Class B Stock at $17.55092 per share and 1,262,000 shares of Series A
Preferred Stock at $17.82884 per share representing, in the aggregate, 37.381%
of the Company's capital stock on a fully-diluted basis (giving effect to the
conversion of the Series A Preferred Stock and Class B Stock into shares of
Common Stock in accordance with their terms) to the Private Equity Investors;
and (ii) the Senior Subordinated Notes bearing interest at 10.101% per annum.
The Company has paid an aggregate of $1,422,557 in interest on the Senior
Subordinated Notes quarterly, and intends to use the net proceeds of this
offering to pay the outstanding principal amount of and accrued interest on the
Senior Subordinated Notes. See "Use of Proceeds."
 
1995 TRANSACTION
 
    Following the Recapitalization, the Company grew rapidly in terms of gross
revenues derived from new CDIP contracts. During the third quarter of 1995,
however, then existing management and the Private Equity Investors recognized
that there were significant problems managing the rapid growth of the business
and that the financial condition of the Company had deteriorated during 1995 as
evidenced by substantial operating losses. As a result, in September 1995 the
Company, together with the Redeemed Holders, the Private Equity Investors and
certain others completed the 1995 Transaction, which resulted in changes to the
capitalization, management and business of the Company. The principal components
of the 1995 Transaction included a return of capital to the Company by the
Redeemed Holders as well as significant adjustments to the relative equity
positions of the Company's shareholders, a new management team and development
and introduction of the RMP product. See "Business--Strategy."
 
    In the 1995 Transaction: (i) the Redeemed Holders subsequently reduced the
aggregate redemption price paid at the time of the Recapitalization by
$7,500,000 through a combination of cash payments and the delivery of
irrevocable letters of credit and promissory notes to the Company; (ii) the
 
                                       53
<PAGE>
holders of the Junior Subordinated Notes irrevocably waived their right to
receive any and all accrued and unpaid interest thereon and agreed that no
further interest would accrue; (iii) Whitney Debt Fund and CCP exchanged an
aggregate of 22,969 shares of Common Stock for 92,004 shares of Series A
Preferred Stock and 31,152 shares of Class B Stock and the conversion ratios
applicable to the conversion of Series A Preferred Stock and Class B Stock into
Common Stock were adjusted so that the Private Equity Investors' percentage
ownership of the Company, immediately prior to the consummation of this offering
and assuming conversion of all shares of Series A Preferred Stock and Class B
Stock into Common Stock, increased from 37.4% to 73.0% on a fully diluted basis;
(iv) the Private Equity Investors obtained control of the Board pursuant to an
amendment to the Shareholders' Agreement; and (v) Dr. Mintz resigned as
President and Chief Executive Officer and agreed to a $100,000 reduction in his
salary.
 
    The Company also issued the Stock Purchase Warrants to the Redeemed Holders
and certain other members of the management for the purchase of an aggregate of
641,236 shares of Common Stock that are exercisable at an exercise price of $.05
per share only if, on or prior to June 30, 1997 (or, under certain conditions,
prior to September 30, 1997), (i) the Company consummates an initial public
offering of the Common Stock such that (a) the net cash proceeds to the Company
from such offering exceed $30 million and (b) the price per share of Common
Stock sold in such offering is at least $24.90 or (ii) there occurs on or prior
to June 30, 1997 (or, under certain conditions, September 30, 1997), a sale of
the capital stock of the Company held by the Private Equity Investors or a
merger, consolidation or other business combination, and in each case, (x) the
Senior Subordinated Notes are repaid in full and (y) the Private Equity
Investors receive cash proceeds (net of certain expenses and fees) that exceed
$75 million for the Class B Stock and Series A Preferred Stock held by the
Private Equity Investors. If the Stock Purchase Warrants do not become
exercisable upon the consummation of this offering they may become exercisable
in the future upon a sale of the stock of the Company under the conditions
specified in clause (ii) above. See "Risk Factors--Dilution," "Capitalization"
and "Principal Shareholders."
 
    In connection with the 1995 Transaction, the Company entered into amendments
to the employment agreements of Alan H. Spiro, M.D., Lawrence Rubinstein and
James E. Zechman. See "Management--Employment Agreements."
 
    Dr. Spiro executed a promissory note (the "Spiro Note") in favor of the
Company to evidence (i) a demand loan in the original principal amount of
$150,000 advanced to Dr. Spiro by the Company on April 14, 1995 and (ii) an
initial advance of $374,625 on September 6, 1995 to satisfy certain of Dr.
Spiro's obligations arising out of the 1995 Transaction. The Spiro Note (i) is
secured by a pledge of 53,487 shares of Common Stock to the Company owned by Dr.
Spiro, (ii) matures on the earlier to occur of September 6, 2005 or Dr. Spiro
ceasing to be an employee of the Company (subject in some cases to a grace
period before repayment) and (iii) is subject to certain mandatory prepayment
events.
 
    Prior to the 1995 Transaction, the Company entered into long term employment
arrangements with Jack Korsower, M.D. and Maria McAfee to assist in the
development of physician networks for the Company. As these arrangements
contained economic terms that were unfavorable to the Company, the new
management team renegotiated Ms. McAfee's employment arrangement and reached a
mutually agreeable termination of Dr. Korsower's employment arrangement.
 
    The Company and Ms. McAfee agreed to shorten the term of her employment
agreement from five years to one year (subject to renewal each year) and to
reduce her base salary to less than 50% of its previous level. Simultaneously
therewith, the Company issued 55,298 shares of Common Stock to Ms. McAfee
pursuant to a restricted shares agreement, all of which will vest on June 30,
1996. Ms. McAfee also received a stock option, which has been exercised, for
3,029 shares of Common Stock and the Company made a loan to her in the amount of
$137,000 pursuant to a promissory note (the "McAfee Note") that is secured by a
pledge of 55,298 shares of the Common Stock of the Company owned by Ms. McAfee.
The McAfee Note bears interest at 6% per annum and is repayable on the earlier
of November 15, 1999 or the occurrence of certain events specified therein.
 
                                       54
<PAGE>
    On February 15, 1996 the Company and Dr. Korsower entered into a severance
agreement pursuant to which the parties agreed upon a mutual release. Dr.
Korsower agreed to certain noncompetition, nonsolicitation and confidentiality
covenants and the Company agreed to the issuance of certain stock options, the
payment over three fiscal quarters of severance totaling $72,604 and the
issuance of the Korsower Note. The Korsower Note bears interest at 8.5% per
annum and matures by its terms on the closing of this offering. The Company
intends to pay the outstanding principal amount and accrued interest of the
Korsower Note with the net proceeds of this offering. See "Use of Proceeds."
 
    Simultaneously with the hiring of Dr. Adkins to lead the Company's
management team, Dr. Mintz reduced his role solely to that of non-executive
Chairman and, effective as of December 31, 1995, the Company and Dr. Mintz
entered into a severance agreement (the "Mintz Severance Agreement"). Pursuant
to the Mintz Severance Agreement: (i) the Company agreed to allow Dr. Mintz to
reduce the amount of the letter of credit he posted with the Company in
connection with the 1995 Transaction by $430,898 in lieu of payment of any
severance or other monies to him, including with respect to any indebtedness for
personal funds previously deposited with the Company; (ii) Dr. Mintz agreed to
certain noncompetition, nonsolicitation and confidentiality obligations; and
(iii) the parties agreed to a mutual release. Simultaneously with the Mintz
Severance Agreement, the Company entered into a Settlement Agreement with Dr.
Michael P. Grossman, a former business partner of Dr. Mintz, pursuant to which
the Company paid Dr. Grossman, a former shareholder of a predecessor of the
Company, $100,000 as part of the settlement of a lawsuit between Dr. Grossman
and Dr. Mintz. The Company was not a party to such suit and received a release
of any potential claims Dr. Grossman may have had against the Company.
 
    The employment of Cheryl Lippert, who served as Chief Financial Officer from
May 1995 to January 1996, was terminated effective January 11, 1996. The Company
and Ms. Lippert entered into a settlement agreement and general release pursuant
to which Ms. Lippert (i) received cash payments totaling $95,500 and (ii) agreed
to release the Company from any and all claims related to her employment with
the Company and her termination therefrom.
 
SENIOR NOTES
 
    On March 6, 1996, the Company issued the Senior Notes to CCP and Whitney.
The Company used the proceeds of the Senior Notes issued to CCP and Whitney on
March 6, 1996 to fund a substantial amount of the deposit to a client in
connection with the renegotiation of a CDIP contract. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Clients; Capitation Contracts and Provider Contracts; RMP Contracts."
The Senior Notes bear interest at a rate of 14% per annum until September 6,
1996, after which time the rate increases to 16% per annum. The Company has paid
quarterly interest of $56,000 on the Senior Notes since March 31, 1996. The
Company intends to use a portion of the net proceeds of this offering to pay the
outstanding principal amount of and accrued interest on the Senior Notes, as
well as an additional $1 million representing certain deferred fees to the
Private Equity Investors incurred in connection with the issuance of the Senior
Notes. See "Use of Proceeds."
 
SHAREHOLDERS' AGREEMENT
 
    In connection with the Recapitalization, the Company entered into a
shareholders' agreement with the Private Equity Investors, the Redeemed Holders
and certain others governing the relationships among such shareholders (as
amended, the "Shareholders' Agreement"), which agreement will be terminated upon
the consummation of this offering. The Shareholders' Agreement provides for
restrictions on transfers of shares, rights of first refusal, tag-along
registration rights and election of directors. The members of the Board were
elected pursuant to the terms of the Shareholders' Agreement, which requires all
the parties to vote their shares in favor of a Board consisting of one member
designated by Whitney, two members designated by Whitney Equity Fund, three

shareholders of the Company and three members designated by the vote of a
majority of the other members of the Board.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market could adversely affect the prevailing market price from time to time.
Since only a limited number of shares will be available for sale shortly after
this offering because of certain contractual and legal restrictions on resale
(as described below), sales of substantial amounts of Common Stock in the public
market after the restrictions lapse could adversely affect the prevailing market
price.
 
    Upon completion of this offering, 6,762,147 shares of Common Stock will be
outstanding. Of these shares, the 2,500,000 shares of Common Stock sold in this
offering will be freely tradeable by persons other than "affiliates" of the
Company, without restriction under the Securities Act and the remaining
4,262,147 shares of Common Stock outstanding will be "restricted" securities
within the meaning of Rule 144 under the Securities Act and may not be sold in
the absence of registration under the Securities Act unless an exemption from
registration is available, including the exemption contained in Rule 144. As
defined in Rule 144, an "affiliate" of an issuer is a person that directly, or
indirectly through one or more intermediaries, controls, or is controlled by, or
is under common control with, such issuer.
 
    Upon completion of this offering, the holders of       shares of Common
Stock, or their transferees, will be entitled to certain registration rights for
such shares under the Securities Act. See "Description of Capital Stock --
Registration Rights." Registration of such shares under the Securities Act would
result in such shares (except for shares purchased by affiliates) being
available for sale immediately upon the effectiveness of such registration.
 
    All directors, executive officers and existing shareholders of the Company,
holding in the aggregate all of the shares of Common Stock outstanding prior to
this offering, have agreed with the Underwriters not to sell or otherwise
dispose of any shares of Common Stock for a period of 180 days after the date of
this Prospectus without the prior written consent of Morgan Stanley & Co.
Incorporated. However, Morgan Stanley & Co. Incorporated may in its sole
discretion and at any time without notice, release all or any portion of the
securities subject to such agreements. See "Underwriters." The number of shares
of Common Stock available for sale in the public market is further limited by
restrictions under the Securities Act. Separately, Dr. Mintz and Messrs. Adams
and Rubinstein have agreed that for a period of two years following the
consummation of this offering, except upon exercise of certain registration
rights (see "Description of Capital Stock--Registration Rights"), they will not
effect any public sale or distribution of Common Stock without the prior written
consent of Whitney and CCP.
 
    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least two years, including
persons who may be deemed "affiliates" of the Company, would be entitled to sell
within any three-month period a number of shares that does not exceed the
greater of one percent of the number of shares of Common Stock then outstanding
or the average weekly trading volume of the Common Stock as reported through
Nasdaq National Market during the four calendar weeks preceding the filing of a
Form 144 with respect to such sale. Sales under Rule 144 are also subject to
certain manner of sale provisions and notice requirements and to the
availability of current public information about the Company. In addition, a
person who is not deemed to have been an affiliate of the Company at any time
during the 90 days preceding a sale, and who has beneficially owned for at least
three years the restricted shares proposed to be sold, would be entitled to sell
such shares under Rule 144(k) without regard to the volume limitation, manner of
sale provisions, public information requirements or notice requirements. The
Commission has proposed to amend the holding periods of Rule 144 by reducing the
two year period referred to above to one year and the three year period referred
to above to two years. The proposed amendments have not yet been adopted.
 
    Subject to certain limitations on the aggregate offering price of a
transaction and certain other conditions, Rule 701 permits resales of shares
issued prior to the date the issuer becomes subject to the
 
                                       56
<PAGE>
reporting requirements of the Exchange Act pursuant to certain compensatory
benefit plans and contracts commencing 90 days after the issuer becomes subject
to the reporting requirements of the Exchange Act, in reliance upon Rule 144 but
without compliance with certain restrictions, including the holding period
requirements, contained in Rule 144. In addition, the Commission has indicated
that Rule 701 will apply to typical stock options granted by an issuer before it
becomes subject to the reporting requirements of the Exchange Act, along with
the shares acquired upon exercise of such options (including exercises after the
date of this Prospectus). Securities issued in reliance on Rule 701 are
restricted securities and, subject to the contractual restrictions described
above, beginning 90 days after the date of this Prospectus, may be sold by
persons other than affiliates pursuant to the manner of sale provisions of Rule
144 and by affiliates without compliance with the two-year minimum holding
period requirements under Rule 144.

                          DESCRIPTION OF CAPITAL STOCK
 
    The Company has amended and restated the Articles of Incorporation (the
"Articles") and Bylaws of the Company (the "Bylaws") to take effect upon the
effective date of the Registration Statement.
 
AUTHORIZED AND OUTSTANDING CAPITAL STOCK
 
    Prior to the consummation of this offering, the Company's capital stock
consisted of one series of preferred stock (1,354,004 Series A Preferred Stock,
all of which were issued and outstanding) and two classes of common stock
(27,158,071 shares of Common Stock, of which [       ] shares were issued and
outstanding and 458,480 shares of Class B Stock, all of which shares were issued
and outstanding). Immediately prior to the consummation of this offering, all of
the issued and outstanding shares of Series A Preferred Stock and Class B Stock
will be converted into shares of Common Stock and the Company will effectuate a
5.361849 for one reverse stock split. As a result of the foregoing, immediately
prior to the consummation of this offering and after such conversion and reverse
stock split, all shares of Series A Preferred Stock and Class B Stock shall be
cancelled, retired and eliminated from the Company's authorized shares of Series
A Preferred Stock and Class B Stock.
 
    Upon the consummation of this offering, the authorized capital stock of the
Company will consist of [      ] shares of Common Stock, of which 6,762,147 will
be issued and outstanding, and [      ] shares of preferred stock, no par value
("Preferred Stock"), none which will be issued. The description of the capital
stock below is qualified in its entirety by reference to the Articles and
Bylaws, which are filed as exhibits to the Registration Statement and
incorporated by reference herein.
 
COMMON STOCK
 
    Holders of Common Stock are entitled to one vote for each share of Common
Stock held of record by such holder on all matters on which shareholders
generally are entitled to vote under Illinois law. Voting rights are not
cumulative, so that the holders of a majority of the voting power of the Company
would elect all the directors standing for election at any annual or special
meeting of the shareholders, and the holders of the remaining shares may not be
able to elect any director.
 
    The holders of the Common Stock are entitled to receive ratably dividends
only when and if declared by the Board out of funds legally available for
payment thereof. The ability of the Board to declare or pay dividends on Common
Stock or to cause the Company to repurchase shares of its capital stock may be
subject to restrictions or limitations contained in the provisions of any series
of Preferred Stock which may hereafter be issued by the Company.
 
    Upon the liquidation, dissolution or winding up of the Company, or any
distribution of its assets, the holders of the Common Stock will be entitled to
receive ratably the assets of the Company available after the payment of all
debts and other liabilities and after the holders of any series of Preferred
Stock which may be issued have received the preferential amount fixed by the
Board for such shares.
 
    The holders of Common Stock have no preemptive rights to purchase shares of
capital stock of the Company. Shares of Common Stock are not subject to any
redemption provisions and are not convertible into any other securities or
property. The rights, preferences and privileges of the holder of Common Stock
are subject to, and may be adversely affected by, the rights of the holders of
the shares of any series of Preferred Stock which the Company may designate and
issue in the future. All outstanding shares of Common Stock are fully-paid and
non-assessable and the shares of Common Stock offered will be fully-paid and
non-assessable when issued.
 
PREFERRED STOCK
 
    Pursuant to the Articles, the Board, without further shareholder
authorization, is authorized to issue shares of Preferred Stock in one or more
series and to determine and fix the rights, preferences and privileges of each
series, including dividend rights and preferences over dividends on the Common
Stock
 
                                       58
<PAGE>
and one or more series of the Preferred Stock, conversion rights, voting rights
(in addition to those provided by law), redemption rights and the terms of any
sinking fund therefor, and rights upon liquidation, dissolution or winding up,
including preferences over the Common Stock and one or more series of the
Preferred Stock. Although the Company has no plan to issue any shares of
Preferred Stock, the issuance of shares of Preferred Stock, or the issuance of
rights to purchase such shares, may have the effect of delaying, deferring or
preventing a change in control of the Company or an unsolicited acquisition
proposal.
 
DIRECTOR'S AND OFFICER'S LIABILITY
 
    The Company has included in its Articles provisions to eliminate the
personal liability of its directors and officers for monetary damages resulting
from breaches of their fiduciary duty. This provision does not eliminate
liability for breaches of the duty of loyalty, acts or omissions not in good
faith or which involve gross negligence or willful misconduct. These provisions
will not limit the liability of the Company's directors under the Federal
securities laws. The Company believes that these provisions are necessary to
attract and retain qualified persons as directors and officers.
 
REGISTRATION RIGHTS
 
    At the completion of this offering, certain persons and entities the
("Rightsholders") will be entitled to certain rights with respect to the
registration under the Securities Act of a total of approximately
shares of Common Stock (the "Registerable Shares") under the terms of a
registration rights agreement entered into in connection with the
Recapitalization (the "Registration Rights Agreement"). In general, the
Registration Rights Agreement provides that in the event the Company proposes to
register any of its securities under the Securities Act for its own account or
for the account of other shareholders at any time or times subject to certain
exceptions, the Rightsholders shall be entitled to include certain Registerable
Shares in such registration, subject to the right of the managing underwriter of
any such offering to exclude for marketing reasons certain of such Registerable
Shares from such registration. Certain Rightsholders have the additional right
under the Registration Rights Agreement to require the Company to prepare and
file from time to time up to four registration statements under the Securities
Act with respect to their Registerable Shares if Rightsholders holding at least
25% of the Registerable Shares so request, and the Company is required to use
its best efforts to effect such registration, subject to certain conditions and
limitations. The Company is generally required to bear the expenses of all such
registrations. All the Registerable Shares are subject to the contractual
restrictions with respect to the sale or disposition of shares of Common Stock.
See "Shares Eligible for Future Sale."
 
ILLINOIS TAKEOVER STATUTE
 
    Upon the consummation of this offering, the Company will become subject to
Section 7.85 of the IBCA and, at such times as a certain amount of shares are
held by or a certain number of shareholders are Illinois residents, Section
11.75 of the IBCA. These statutes place restrictions on business combinations
between certain Illinois corporations and Interested Shareholders as defined in
the respective sections.
 
    Section 7.85 of the IBCA requires, in addition to any other requirements
imposed by law or a corporation's Articles of Incorporation, that a business
combination (as defined in the statute) involving a corporation and an
Interested Shareholder be approved by: (i) the affirmative vote of the holders
of at least 80% of the combined voting power of the voting shares (as defined in
the statute), voting together as a single class (but with the votes per share
specified in the corporation's Articles of Incorporation) and (ii) the
affirmative vote of a majority of the combined voting power of the then
outstanding voting shares held by disinterested shareholders voting together as
a single class. These voting requirements will not apply if the business
combination is approved by 66 2/3% of the disinterested directors, the price
paid to the shareholders of the corporation in such business combination is,
generally, the higher of fair market value (as defined in the statute) or the
price per share paid by the interested shareholder in
 
                                       59
<PAGE>
acquiring its shares, and certain other conditions are met relating to the form
of consideration paid, the absence of dividend defaults, the absence of special
benefits to the interested shareholder and the provision of information to
shareholders. Section 7.85 of the IBCA defines an Interested Shareholder as a
person who (i) beneficially owns, directly or indirectly, 10% or more of the
combined voting power of the outstanding voting shares of a corporation or (ii)
is an affiliate or associate (as those terms are defined in Rule 12b-2 of the
Exchange Act) of the corporation and was the beneficial owner, directly or
indirectly, of 10% or more of the combined voting power of the then outstanding
voting shares at any time in the previous two years.
 
    Section 11.75 of the IBCA prohibits a business combination (as defined in
the statute) involving a corporation and an Interested Shareholder for three
years after such shareholder becomes an Interested Shareholder unless: (i) prior
to such date, the Board of Directors approved the transaction that resulted in
the shareholder becoming an Interested Shareholder, (ii) upon completion of the
transaction that resulted in the shareholder becoming an Interested Shareholder,
the Interested Shareholder owned at least 85% of the voting shares outstanding
at the time such transaction commenced (excluding shares owned by directors who
are also officers and shares reserved under employee stock plans), or (iii) on
or after such date, the business combination is approved by the Board of
Directors and authorized at a meeting of the shareholders by 66 2/3% of the
outstanding voting shares not owned by the Interested Shareholder. For purposes
of Section 11.75 of the IBCA, an Interested Shareholder is a person who (i) owns
15% or more of the outstanding voting shares of a corporation or (ii) is an
affiliate or associate (as defined in the statute) of the corporation and was
the owner of 15% or more of the then outstanding voting shares at any time in
the previous three years.
 
    Section 8.85 of the IBCA permits directors and officers to consider the
interests of certain constituencies other than the shareholders when exercising
their duties, including in the consideration of actions which could result in a
change of control of the Company.

    The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by counsel
and to certain other conditions. The Underwriters are obligated to take and pay
for all the shares of Common Stock offered hereby (other than the shares of
Common Stock covered by the over-allotment option described below) if any such
shares are taken.
 
    The Underwriters initially propose to offer part of the shares of Common
Stock directly to the public at the public offering price set forth on the cover
page hereof and part to certain dealers at a price that represents a concession
not in excess of $    a share under the public offering price. Any Underwriter
may allow, and such dealers may reallow, a concession not in excess of $    a
share to other Underwriters or to certain other dealers. After the initial
offering of the shares of Common Stock, the offering price and other selling
terms may from time to time be varied by the Underwriters.
 
    The Company and the Underwriters have agreed in the Underwriting Agreement
to indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
    The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of 375,000
additional shares of Common Stock at the public offering price set forth on the
cover page hereof, less underwriting discounts and commissions. The Underwriters
may exercise such option solely for the purpose of covering over-allotments, if
any, made in connection with the offering of the shares of Common Stock offered
hereby. To the extent such option is exercised, each Underwriter will become
obligated, subject to certain conditions, to purchase approximately the same
percentage of such additional shares of Common Stock as the number set forth
next to such Underwriter's name in the preceding table bears to the total number
of shares of Common Stock offered by the Underwriters hereby.
 
    The Company and its executive officers and directors, and certain
shareholders of the Company have agreed that they will not (a) offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock, or (b) enter into any swap or other agreement that transfers, in
whole or in part, any of the economic consequences of ownership of the Common
Stock, whether any such transaction described in clause (a) or (b) above is to
be settled by delivery of Common Stock or other securities, in cash or otherwise
for a 180-day period after the date of this Prospectus, without the prior
written consent of Morgan Stanley & Co. Incorporated, except that the Company
may, without such consent, grant options or issue stock upon the exercise of
outstanding stock options, pursuant to the Company's stock option plans.
 
    Prior to this offering, there has been no public market for the Common
Stock. The initial public offering price was determined through negotiations
among the Company and the Underwriters. Among the factors considered in such
negotiations, in addition to prevailing market conditions, were price-earnings
ratios of publicly traded companies that the Company and the Underwriters
believe to be
 
                                       61
<PAGE>
comparable to the Company, the Company's results of operations in recent
periods, estimates of the business potential and earnings prospects of the
Company, the present state of the Company's development and the current state of
the Company's industry and the economy as a whole. The initial public offering
price set forth on the cover page of the Prospectus should not, however, be
considered an indication of the actual value of the Common Stock. Such price is
subject to change as a result of market conditions and other factors.
 
    The Company will apply for listing of the Common Stock on the Nasdaq
National Market, under the symbol "ULMD," subject to official notice of
issuance. In connection with the listing, the Underwriters have undertaken that
sales of Common Stock will meet the Nasdaq National Market's minimum
distribution standards.
 
                             ADDITIONAL INFORMATION
 
    The Company has filed with the Commission, a Registration Statement on Form
S-1 under the Securities Act with respect to the Common Stock offered hereby.
This Prospectus does not contain all of the information set forth in the
Registration Statement and the exhibits and schedules thereto. For further
information with respect to the Company and the Common Stock, reference is
hereby made to such Registration Statement and the exhibits and schedules
thereto. Statements contained in this Prospectus as to the contents of any
contract or other documents are not necessarily complete and, in each instance,
reference is made to the copy of such contract or document filed as an exhibit
to the Registration Statement, each such statement being qualified in all
respects by such reference. The Registration Statement, including exhibits
thereto, may be inspected and copied at the public reference facilities
maintained by the Commission at Judiciary Plaza, 450 Fifth Street, N.W., Room
1024, Washington, D.C. 20549 and at the Commission's Regional Offices located at

    During December 1995, the Board decided to retain Ernst & Young LLP as its
independent public accountants and dismissed the Company's former auditors. The
former auditors' report on the Company's financial statement for the two years
ended December 31, 1994 does not cover the consolidated financial statements of
the Company included in this Prospectus. Such report did not contain an adverse
opinion or disclaimer of opinion and was not modified as to uncertainty, audit
scope or accounting principles. There were no disagreements with the former
auditors on any matter of accounting principles or practices, financial
statement disclosure or auditing scope or procedure at the time of the change or
with respect to the Company's financial statements for fiscal years 1993 and
1994, which, if not resolved to the former auditors' satisfaction, would have
caused them to make reference to the subject matter of the disagreement in
connection with their report. Prior to retaining Ernst & Young LLP, the Company
had not consulted with Ernst & Young LLP regarding accounting principles.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors
UtiliMed, Inc.
 
    We have audited the accompanying consolidated balance sheets of UtiliMed,
Inc. (the Company) as of December 31, 1994 and 1995, and the related
consolidated statements of operations, changes in shareholders' equity (deficit)
and cash flows for each of the three years in the period ended December 31,
1995. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the Company
at December 31, 1994 and 1995, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1995, in
conformity with generally accepted accounting principles.

                     (MARCH 31, 1996 AMOUNTS ARE UNAUDITED)
 
1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
    UtiliMed, Inc. (formerly Medicon, Inc.) and subsidiaries (the Company)
contracts with managed care organizations and diagnostic imaging providers
throughout the United States to manage the utilization and quality of diagnostic
imaging services. Customers of the Company representing more than ten percent of
total contract revenues are as follows: 1993--32%, 23% and 22%; 1994--22%, 16%,
11% and 10%; 1995--20%, 14% and 14%; and 1996--20%, 15% and 16%.
 
    The accompanying consolidated financial statements have been prepared in
accordance with generally accepted accounting principles (GAAP). The preparation
of financial statements in conformity with GAAP requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates. The accompanying consolidated financial statements include the
accounts of the Company and its wholly owned subsidiaries, UtiliMed C I, Inc.
(formerly Medicon C I, Inc.) and UtiliMed P II, Inc. (formerly Medicon P II,
Inc.) All significant intercompany accounts and transactions have been
eliminated.
 
CONTRACT REVENUES AND COST OF SERVICES
 
    The Company's contract revenues are derived primarily from services rendered
under contracts with managed care organizations which pay a fixed monthly
capitated charge for each covered member. Cost of services represents payments
to providers for covered diagnostic imaging services. Certain full-service
network providers of diagnostic imaging services receive a contracted, fixed
monthly amount per covered managed care member, subject to various utilization
adjustments. The Company also pays other network providers of specialty
diagnostic imaging services a contracted fee per incident of care rendered.
Under certain managed care contracts, the Company is also obligated to pay
noncontracted providers of covered diagnostic imaging services on a
fee-for-service basis. Accordingly, the Company's revenues are primarily fixed
while the cost of services will vary based upon the services rendered and the
contractual relationship with the providers.
 
    During 1995, the Company began providing resource management services. Under
these agreements, the Company receives an administrative fee per covered managed
care member to provide various managed care services including credentialing,
pre-certification and utilization review. Under certain of these contracts, the
administrative fee received may be increased or decreased based upon the
achievement of various performance criteria. Included in 1995 and 1996 contract
revenues is $1,763,000 and $2,121,000, respectively, of administrative fee
revenue related to resource management services.
 
    Revenues and cost of services are recognized for financial reporting
purposes in the period in which the services are provided.
 
    "Contract revenues--terminated contracts" and "Costs of services--terminated
contracts" represent amounts related to certain unprofitable contracts
terminated during 1995.
 
LOSS CONTRACTS
 
    Based upon analysis of individual contracts, management establishes a loss
contract accrual for the excess of estimated future cost of services over
estimated future contract revenue for the remaining

contract period. Loss contract accruals are charged to earnings when known and
amortized over the remaining term of the specific contracts.
 
CONTRACT DEVELOPMENT COSTS
 
    All costs incurred related to obtaining and implementing client contracts
are expensed as incurred. These costs include marketing and business development
activities conducted before the client contract is probable, as well as direct
contract costs and indirect overhead costs associated with the implementation of
new client accounts.
 
    During 1992 and 1993, the Company capitalized contract development costs.
During 1994, in conjunction with the decision to seek equity financing, the
Company changed its method of accounting to expense contract development costs
as incurred. The consolidated financial statements for 1993 were restated to
give effect to this change.
 
STOCK-BASED COMPENSATION
 
    The Company measures the compensation cost of all stock-based employee
compensation using the intrinsic value based method of accounting prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees." Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation," which is effective for fiscal years beginning after
December 15, 1995, encourages, but does not require, all entities to adopt the
fair value based method of accounting for stock-based employee compensation.
While management continues to evaluate this new pronouncement, management
anticipates electing the option of continuing to use APB 25 in the preparation
of consolidated financial statements.
 
CASH EQUIVALENTS
 
    Cash equivalents consist of highly liquid short-term investments with a
maturity at date of acquisition of three months or less.
 
EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
    Equipment and leasehold improvements are stated at cost. Depreciation and
amortization are computed using straight-line methods for financial reporting
purposes and accelerated methods for tax purposes over the estimated useful
lives of the respective assets (3 -- 7 years) or, for capital leases, the terms
of the related leases.
 
DEPOSIT WITH MANAGED CARE ORGANIZATION
 
    Deposit with managed care organization represents interest bearing funds
deposited under the terms of one of the Company's contracts.
 
INCOME TAXES
 
    The Company accounts for income taxes using the liability method. Deferred
income taxes reflect the tax effects of temporary differences between the
carrying amounts of assets and liabilities for financial statement purposes and
amounts used for income tax purposes.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-- (CONTINUED)
 
1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES-- (CONTINUED)
PAYABLES TO PLANS AND PROVIDERS
 
    Payables to plans and providers include estimates of reported and unreported
services provided and accrued capitation fees and adjustments, which are unpaid
as of the balance sheet date. These payables estimates are based on statistical
information and revised as additional information becomes available. Any
adjustments resulting from these revisions are reflected in earnings currently.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The Company believes that it is not practicable to estimate the fair value
of redeemable, convertible Series A preferred stock, redeemable, convertible
Class B stock or long-term debt obligations due to the significant restrictions
imposed on these instruments and the absence of a market for these instruments.
 
DEFERRED DEBT ISSUANCE COSTS
 
    During 1994, the Company deferred approximately $758,000 of expenses
directly related to certain financing transactions completed during the year.
The junior subordinated notes payable were converted to equity effective as of
December 31, 1995, and the corresponding $376,000 of unamortized deferred debt
issuance costs were transferred to shareholders' deficit.
 
NET LOSS PER SHARE
 
    Net loss per share is computed by dividing net loss by the number of common
and common equivalent shares outstanding during the periods in accordance with
the applicable rules of the Securities and Exchange Commission. All stock
options and restricted common stock issued have been considered as outstanding
common stock equivalents for all periods presented, even if anti-dilutive, under
the treasury stock method (based on initial public offering price). Shares of
common stock issuable upon conversion of the Series A preferred stock and Class
B stock are assumed to be common share equivalents for all periods presented.
 
    Additionally, the number of shares used to compute the fully diluted net
loss per share includes shares issuable upon conversion of the junior
subordinated notes which have been treated as converted into common shares as if
such shares had been outstanding since January 1, 1995. All contingent warrants
for the purchase of shares of common stock have been considered as outstanding
common stock equivalents for all periods presented, even if anti-dilutive, under
the treasury stock method (based upon the contingent price specified in the
warrants). The net loss used to compute the fully diluted net loss per share has
been reduced by interest of $529,000 expensed in 1995 related to the junior
subordinated notes.
 
2. OPERATIONAL MATTERS
 
    The Company has experienced significant growth in new managed care contracts
and the number of covered lives. Revenues increased 45% from $66,579,000 in 1994
to $96,417,000 in 1995. The costs of negotiating new managed care contracts,
establishing provider networks to service the contracts, and implementing new
contracts are charged to operations as such costs are incurred. In addition,
certain contracts were not favorable to the Company. The Company experienced net
losses of $13,879,000 and $18,774,000 for the years 1994 and 1995, respectively,
and negative cash flows of $14,522,000 for the year ended December 31, 1995. At
December 31, 1995, the Company has an accumulated deficit of $76,165,000 and
current liabilities exceeded current assets by $18,644,000.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-- (CONTINUED)
 
2. OPERATIONAL MATTERS-- (CONTINUED)
    Beginning in mid-1995, the Company implemented a number of operational
initiatives to improve profitability, including the engagement of a new
executive management team with more experienced professionals in finance,
operations, claims management and professional relations; the termination of
certain unprofitable contracts and the amendment of other contracts to improve
profitability; and the reduction of costs through a specific program.
 
    In addition, certain shareholders provided financial support to the Company
in exchange for $6 million of senior promissory notes in March 1996 (see Note
4), and such shareholders have committed to provide additional financial support
of up to $3 million should such financial support be necessary in 1996. The
Company is in discussions with investment bankers and intends to raise
additional equity capital in 1996 to provide for its expansion and working
capital needs beyond 1996.
 
    Assurances cannot be given that the Company will be successful in raising
additional capital through an initial public offering or in achieving profitable
operations and generating positive cash flow.
 
3. RISKS AND UNCERTAINTIES
 
PAYABLES TO PLANS AND PROVIDERS
 
    While management has recorded their best estimate of payables to plans and
providers, considerable variability is inherent in this estimate given the
limited historical data available to project the liability. Actual results
inevitably will differ from these estimates, and such differences may adversely
affect the financial statements.
 
CONTRACT TERMINATIONS
 
    Certain of the Company's contracts with managed care organizations and
diagnostic imaging providers include termination provisions which provide for
unilateral contract termination prior to expiration of the contract term. Early
termination of contracts with managed care organizations or diagnostic imaging
providers could adversely affect the Company's operations and cash flows.
 
RESOURCE MANAGEMENT SERVICES PROGRAM
 
    Under the Company's Resource Management Program contracts, a portion or all
of the Company's administrative fee revenues may have to be refunded if the
contract does not result in specified cost savings. In the opinion of
management, the performance criteria will be met and, accordingly, a provision
for possible refund of administrative fees has not been made. Failure to achieve
the contractual performance criteria could adversely affect the Company's
operations and cash flows.

    On November 3, 1994, the Company completed a private debt and equity
placement resulting in a new debt structure. In connection with the placement,
certain Series A preferred and Class B shareholders loaned the Company
$10,000,000 under the terms of senior subordinated note agreements with a face
value of $10,000,000 and with 123,156 shares of common stock attached thereto.
The Company recorded a discount on the senior subordinated notes equal to the
estimated fair market value of the common shares which totaled approximately
$164,000.
 
    Payment of the senior subordinated notes is mandatory when certain events
occur, including a change in control of the Company, as defined, or the
completion of an initial public offering of the Company's stock.
 
    If the Company fails to achieve certain annual earnings before interest,
taxes, depreciation and amortization (EBITDA) and revenue targets, as defined,
the holders of the senior subordinated notes may request prepayment. Prepayments
are restricted to the amount by which the current assets of the Company
(excluding receivables and prepaid expenses) exceed 50% of the payables to
providers due within one month. During 1995, the Company did not achieve the
annual EBITDA and revenue targets, as defined. The holders of the notes have
waived their prepayment rights through December 31, 1996, except in the event of
an initial public offering. As a result, the senior subordinated notes have been
classified as a non-current liability.
 
    During 1994, the Company also entered into junior subordinated note
agreements with certain common shareholders in consideration of the redemption
of certain common shares. These junior subordinated notes had a face value of
approximately $10,574,000 and were convertible into common shares at a
conversion rate of $20.971 per share. During 1995, the Company did not achieve
the annual EBITDA and revenue targets specified in the agreements; thus the
junior subordinated notes have been treated as converted into common shares as
of December 31, 1995.

4. DEBT-- (CONTINUED)
    Aggregate maturities of long-term debt are as follows: 1996-$537,000 and
1997-$10,099,000.
 
    The Company paid interest of $158,000 and $2,046,000 in 1995 and 1994,
respectively.
 
    In March 1996, the Company issued $6,000,000 of senior promissory notes due
March 1997, held by certain shareholders. Costs of $1,000,000 were incurred and
capitalized but will not be paid until the debt is repaid in conjunction with
the issuance of these senior promissory notes.
 
5. INCOME TAXES
 
    The Company files a consolidated federal income tax return that includes
both wholly owned subsidiaries.
 
    In connection with certain debt and equity transactions on November 3, 1994,
the Company changed its tax status from that of an S Corporation to a C
Corporation. At the date that the Company became a C Corporation, net deferred
income tax assets, before valuation allowance, of approximately $3,605,000
existed relating to temporary differences.
 
    At December 31, 1995, the Company has net operating loss carryforwards of
$13,700,000 available to offset future taxable income, of which $900,000 expires
in 2009, and $12,800,000 expires in 2010.
 
    Full valuation allowances have been provided against net deferred income tax
assets at December 31, 1994 and 1995, respectively.
 
    The income tax provisions for the years ended December 31, 1994 and 1995,
are as follows:

6. CAPITAL STRUCTURE
 
    On November 3, 1994, the Company completed a private debt and equity
placement. In connection with the placement, the Company authorized a new class
structure, including Series A preferred stock, Class B stock and common stock.
The Company then revised its capital structure by converting each share of
existing common stock to 5,000 shares of common stock. The shares authorized,
issued and outstanding have been restated to give retroactive effect to this
common stock conversion.
 
    The placement also included the issuance of 1,262,000 shares of Series A
preferred stock for cash consideration of $22,500,000 and the issuance of
427,328 shares of Class B stock for cash consideration of $7,500,000.
 
    In connection with the placement, certain Series A preferred and Class B
shareholders loaned the Company $10,000,000 under the terms of senior
subordinated notes with a face value of $10,000,000 and with 123,156 shares of
common stock attached thereto. The Company recorded a discount on the senior
subordinated notes equal to the estimated fair market value of the common shares
(see Note 4). Accordingly, the common shares were valued at approximately
$164,000.
 
    On November 3, 1994, the Company redeemed 2,241,375 common shares for cash
consideration of $26,000,000 and junior subordinated notes totaling
approximately $13,874,000. The redemption of these shares increased the
Company's accumulated deficit by $39,874,000.
 
    On September 6, 1995, the Company completed a capital transaction. In
connection with the restructuring, certain shareholders converted 123,156 shares
of common stock into 31,152 shares of Class B stock and 92,004 shares of Series
A preferred stock. The conversion of these shares reduced common stock by
$164,000 and increased the Company's accumulated deficit by $2,023,000. In
connection with the transaction, certain common shareholders were obligated to
make capital contributions aggregating $7,500,000. As of December 31, 1995,
capital contributions aggregating $5,230,000 had been received by the Company.
The remaining capital contributions of $1,895,000 are backed by irrevocable
letters of credit.

7. LEASE COMMITMENTS
 
    The Company leases certain office facilities and equipment under
noncancellable operating leases. Rental expense was approximately $351,000,

1998-$54,000; and 1999-$2,000.
 
    The Company has a noncancellable office facilities operating lease which had
an initial rent-free period. Deferred rent provides for recognition of lease
expense ratably over the entire lease term.

8. EMPLOYEE BENEFIT PLANS
 
    During 1994, the Company adopted a defined contribution profit-sharing plan
which includes provisions under Section 401(k) of the Internal Revenue Code.
Full-time employees are eligible to participate in the plan after completing six
months of continuous service, as defined. Plan participants may defer up to 15%
of their annual compensation. The Company matches 50% of each participant's
contributions up to a maximum of 6% of the participant's compensation. The
Company may also make discretionary contributions to the plan. The Company's
contribution to the plan was approximately $100,000 and $83,000 during the year
ended December 31, 1995 and 1994, respectively.
 
    The Company has a Time Accelerated Restricted Stock Option Plan (TARSOP) for
certain key employees. All options outstanding under this plan were canceled in
February 1996 and new options for 269,618 shares of common stock with an
exercise price of $.01 per share were granted. The aggregate number of shares of
common stock available for grant under this plan is 269,618. The options granted
vest nine years from the grant date. Vesting may be accelerated if various
performance targets are achieved.
 
    During 1995, the Company granted an employee an option to purchase 16,243
shares of common stock at an exercise price of $.01 per share. The option vested
immediately and expires on November 30, 2004. The option terminates if the
employee leaves the Company's employment.
 
    During 1995, the Company issued 2,337,100 shares of restricted common stock
to employees for cash consideration of $8,000 and as compensation of $15,000.
During January 1996, the Company amended an agreement related to 1,051,561
shares of common stock. The amendment accelerated the vesting provisions of the
original agreement resulting in immediate vesting of 20% with the remainder
vesting over a four year period. Compensation expense is being recognized
related to the amended agreement.
 
    During the first quarter of 1996, the Company granted two former employees
options to purchase 58,899 shares of common stock at an exercise price of $.01
per share. The Company recorded compensation expense for the TARSOP grants and
grants to former employees.
 
    In April 1996, the Company amended the TARSOP increasing the aggregate
number of shares of common stock available for grant to 309,618 and granted
options for 40,000 shares of common stock with an exercise price of $.01. The
Company also granted an employee an option to purchase 271,581 shares of common
stock at an exercise price of $.01 per share. The option vests over five years.
The Company will record compensation expense related to these option grants.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Under Illinois law, a corporation may indemnify any person who was or is a
party or is threatened to be made a party to an action (other than an action by
or in the right of the corporation) by reason of his service as a director or
officer of the corporation, or his service, at the corporation's request, as a
director, officer, employee or agent of another corporation or other enterprise,
against expenses (including attorneys' fees) that are actually and reasonably
incurred by him ("Expenses"), and judgments, fines and amounts paid in
settlement that are actually and reasonably incurred by him, in connection with
the defense or settlement of such action, provided that he acted in good faith
and in a manner he reasonably believed to be in, or not opposed to the
corporation's best interests and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that his conduct was unlawful.
Although Illinois law permits a corporation to indemnify any person referred to
above against Expenses in connection with the defense or settlement of an action
by or in the right of the corporation, provided that he acted in good faith and
in a manner he reasonably believed to be in, or not opposed to the corporation's
best interests, if such person has been judged liable to the corporation,
indemnification is only permitted to the extent that the adjudicating court (or
the court in which the action was brought) determines that, despite the
adjudication of liability, such person is entitled to indemnity for such
Expenses as the court deems proper. The determination as to whether a person
seeking indemnification has met the required standard of conduct is to be made
(1) by a majority vote of a quorum of disinterested members of the board, or (2)
by independent legal counsel in a written opinion, if such a quorum does not
exist or if the disinterested directors so direct, or (3) by the shareholders.
The Business Corporation Act of Illinois also provides for mandatory
indemnification of any director, officer, employee or agent against Expenses to
the extent such person has been successful in any proceeding covered by the
statute. In addition, the Business Corporation Act of Illinois provides the
general authorization of advancement of a director's or officer's litigation
expenses in lieu of requiring the authorization of such advancement by the board
in specific cases, and that indemnification and advancement of expenses provided
by the statute shall not be deemed exclusive of any other rights to
 
                                      II-1
<PAGE>
which those seeking indemnification or advancement of expenses may be entitled
under any by-law, agreement, vote of shareholders or disinterested directors or
otherwise.
 
    The Company's Articles of Incorporation provides that the Company shall
indemnify its directors and officers, and to the extent authorized by the Board,
employees and agents of the Company, to the full extent permitted by the law of
the State of Illinois. In addition, the Articles of Incorporation also permit
the Board to authorize the Company to purchase and maintain insurance against
any liability asserted against any director, officer, employee or agent of the
Company arising out of his or her capacity as such. The Company currently has in
place a standard director and officer liability insurance which, subject to
customary exclusions and specified limits, insures its directors and officers
against certain losses and expenses suffered or incurred by such persons as a
result of serving in such capacity. The Company believes that these provisions
and agreements are necessary to attract and retain talented and experienced
directors and officers.
 
    The Company's Articles of Incorporation provides that the Company's
directors shall not be liable to the Company or its shareholders for monetary
damages for breach of fiduciary duty as a director, except to the extent that
exculpation from liabilities is not permitted under the Illinois Business
Corporation Act as in effect at the time such liability is determined.
 
    The Underwriting Agreement provides for indemnification by the Underwriters
of the Company and its officers and directors for certain liabilities arising
under the Securities Act, or otherwise.
 
    At present, there is no pending litigation or proceeding involving a
director, officer, employee or other agent of the Company in which
indemnification is being sought nor is the Company aware of any threatened
litigation that may result in a claim for indemnification by any director,
officer, employee or other agent of the Company.

ITEM 17. UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
for such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    The undersigned registrant hereby undertakes:
 
        (1) 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 this
    Registration Statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.
 
        (3) To provide to the underwriter at the closing specified in the
    underwriting agreements certificates in such denominations and registered in
    such names as required by the underwriter to permit prompt delivery to each
    purchaser.

          Each of the Purchasers, severally and not jointly, hereby represents
and warrants as follows:

          6.1  Authorization; No Contravention.  The execution, delivery and
               -------------------------------
performance by such Purchaser of this Agreement (a) is within such Purchaser's
power and authority and has been duly authorized by all necessary action,
(b) does not contravene the terms of such Purchaser's organizational documents
or any amendment thereof, and (c) will not violate, conflict with or result in
any breach or contravention of or the creation of any Lien under any Contractual

dispose of all or any part of its Shares or any shares of Class A Common Stock
issued upon conversion of Shares under an effective registration statement under
the Securities Act, or under an exemption from such registration available under
the Securities Act, and subject, nevertheless, to the disposition of such
Purchaser's property being at all times within its control.  If such Purchaser

Purchaser understands and agrees that it may do so only in compliance with the

          7.1  Indemnification.  In addition to all other sums due hereunder or
               ---------------
provided for in this Agreement, the Company and the Management Stockholders each
agree, on a joint and several basis, but subject to Section 7.3, to indemnify
and hold harmless each of the Purchasers and its Affiliates and their respective
officers, directors, agents, employees, subsidiaries, partners and controlling
persons (each, an "Indemnified Party") to the fullest extent permitted by law
                   -----------------
from and against any and all losses, claims, damages, expenses (including,
without limitation, reasonable fees, disbursements and other charges of counsel)
or other liabilities (collectively, "Liabilities") resulting from or arising out

the Company or any of the Management Stockholders in this Agreement, any other

Company or any equity holders of the Company or derivative actions brought by
any Person claiming through or in the Company's name), proceedings or investi-

act, willful misconduct or malpractice that occurred prior to the Closing and
that was performed by any Person in rendering any kind of medical services
whether in the course of their employment with the Company or any of its
Subsidiaries or while acting as their agent or pursuant to any arrangement, be
it contractual or otherwise (but only to the extent the Company's payments with
respect to such negligence, misconduct or malpractice are not covered by
insurance); provided, however, that neither the Company nor any of the
            --------  -------
Management Stockholders shall be liable under this Section 7.1 to an Indemnified
Party (a) for any amount paid in settlement of claims without the Company's
consent (which consent shall not be unreasonably withheld), (b) to the extent
that it is finally judicially determined that such Liabilities resulted
primarily from the willful misconduct or gross negligence of such Indemnified
Party or (c) to the extent that it is finally judicially determined that such
Liabilities resulted from the material breach by such Indemnified Party of any
representation, warranty, covenant or other agreement of such Indemnified Party
contained in this Agreement; provided, further, that if and to the extent that
                             --------  -------
such indemnification is unenforceable for any reason, first the Management
Stockholders shall, on a joint and several basis, make the maximum contribution
to the payment and satisfaction of such Liabilities which shall be permissible
under applicable laws and if and to the extent any such Liabilities are still
not fully satisfied, the Company shall thereafter make the maximum contribution
to the payment and satisfaction of such Liabilities which shall be permissible
under applicable laws.  In connection with the obligations of the Company and
the Management Stockholders to indemnify for expenses as set forth above, the
Company and the Management Stockholders further agree, on a joint and several
basis, upon presentation to the Company of appropriate invoices containing
reasonable detail, to reimburse each Indemnified Party for all such expenses
(including, without limitation, reasonable fees, disbursements and other charges
of counsel) as they are incurred by such Indemnified Party; provided, however,

that, if an Indemnified Party is reimbursed hereunder for any expenses, such
reimbursement of expenses shall be refunded to the extent it is finally judi-
cially determined that the Liabilities in question resulted (a) primarily from
the willful misconduct or gross negligence of such Indemnified Party or (b) from
the material breach by such Indemnified Party of any representation, warranty,
covenant or other agreement of such Indemnified Party contained in this
Agreement.  For the benefit of the Purchasers, the Management Stockholders also
agree to waive all right to contribution from the Company and agree that they
will in no event seek contribution from the Company resulting from or

arising out of the payment and satisfaction of Liabilities hereunder.

          7.2  Notification.  Each Indemnified Party under this Article 7 will,
               ------------
promptly after the receipt of notice of the commencement of any action,
investigation, claim or other proceeding against such Indemnified Party in
respect of which indemnity may be sought from the Company or any of the
Management Stockholders under this Article 7, notify the Company in writing of
the commencement thereof (and the Company shall so notify the Management
Stockholders).  The omission of any Indemnified Party to so notify the Company
of any such action shall not relieve the Company or any of the Management
Stockholders from any liability which any of them may have to such Indemnified
Party (a) other than pursuant to this Article 7 or (b) under this Article 7
unless, and only to the extent that, such omission results in the forfeiture of
substantive rights or defenses.  In case any such action, claim or other
proceeding shall be brought against any Indemnified Party and it shall notify
the Company of the commencement thereof, the Company (but not any Management
Stockholder) shall be entitled to assume the defense thereof at its own expense,
with counsel satisfactory to such Indemnified Party in its reasonable judgment;
provided, however, that any Indemnified Party may, at its own expense, retain
- --------  -------
separate counsel to participate in such defense.  Notwithstanding the foregoing,
in any action, claim or proceeding in which the Company or any of the Management
Stockholders, on the one hand, and an Indemnified Party, on the other hand, is,
or is reasonably likely to become, a party, such Indemnified Party shall have
the right to employ separate counsel at the Company's expense and to control its
own defense of such action, claim or proceeding if, in the reasonable opinion of
counsel to such Indemnified Party, a conflict or potential conflict exists
between the Company or any Management Stockholder, on the one hand, and such
Indemnified Party, on the other hand, that would make such separate representa-
tion advisable.  The Company and the Management Stockholders each agree that it,
she or he, as the case may be, will not, without the prior written consent of
the Purchasers, settle, compromise or consent to the entry of any judgment in
any pending or threatened claim, action or proceeding relating to the matters
contemplated hereby (if any Indemnified Party is a party thereto or has been
actually threatened to be made a party thereto) unless such settlement,
compromise or consent includes an unconditional release of the Purchasers and
each other Indemnified Party from all liability arising or that may arise out of
such claim, action or proceeding.  The Company and the Management Stockholders
shall not be liable for any settlement of any claim, action or proceeding
effected against an Indemnified Party without the Company's

accorded to Indemnified Parties hereunder shall be in addition to any rights
that any Indemnified Party may have at common law, by separate agreement or
otherwise.

          7.3  Limitations on Indemnification.  Notwithstanding any other
               ------------------------------
provision of this Article 7, the indemnification obligation of the Management
Stockholders and the Company hereunder shall be limited as follows:

                 (i)  the Management Stockholders and the Company shall not be
     obligated to make any payment for indemnification pursuant to
     Section 7.1(i) hereof until the aggregate amount of indemnification
     payments under this Agreement and the Subordinated Note and Stock Purchase
     Agreement (other than payments pursuant to Section 7.1(ii) of this
     Agreement and Section 7.1(ii) of the Subordinated Note and Stock Purchase
     Agreement) exceed $500,000.00 (the "Basket Amount"), whereupon the Company
                                         -------------
     and the Management Stockholders shall be obligated to pay in full all such
     amounts for indemnification, including the Basket Amount, subject to clause
     (iii) below; 

                (ii)  the Management Stockholders and the Company shall not be
     obligated to make any payment for indemnification pursuant to Section
     7.1(ii) hereof until the aggregate amount of indemnification payments under
     this Agreement and the Subordinated Note and Stock Purchase Agreement
     (other than payments pursuant to Section 7.1(i) of this Agreement and
     Section 7.1(i) of the Subordinated Note and Stock Purchase Agreement)
     exceed $500,000.00 (the "Insurance Basket Amount"), whereupon the Company
                              -----------------------
     shall be obligated to pay in full all such amounts for indemnification,
     including the Insurance Basket Amount, subject to clause (iii) below; and

               (iii)  none of the Management Stockholders shall be individually
     obligated to pay any amount for indemnification pursuant to Section 7
     hereof and under the Subordinated Note and Stock Purchase Agreement in
     excess of 100% of the aggregate payment received by such Management
     Stockholder from the Company pursuant to the Share Redemption Agreement.

(i) prepare and file SBA Form 468 and any other information requested or
required by any Governmental Authority asserting jurisdiction over such
Purchaser and (ii) confirm that the use of the proceeds of the sale of the
Shares contemplated hereby was as described in Section 8.3.  If the Company
breaches this covenant in any material respect, then in addition to all other
remedies available to the Purchasers, the Purchasers may demand that the Company
repurchase all of the Shares acquired by the Purchasers at the purchase price
thereof.

Affiliate of such Purchaser) to exchange all or any portion of the voting
Securities then held by such Person on a share-for-share basis for shares of a
class of nonvoting Securities of the Company, which nonvoting Securities shall
be identical in all respects to such voting Securities, except that such new
Securities shall be nonvoting and shall be convertible into voting Securities on
such terms as are requested by such Purchaser in light of regulatory
considerations then prevailing, and (iii) to continue and preserve the
respective allocation of the voting interests with respect to the Company
provided for in the Stockholders' Agreement and with respect to such Purchaser's
ownership of the Company's voting Securities.  Such actions may include, but
shall not necessarily be limited to:

                    (B)  entering into such additional agreements, adopting such
          amendments to the Amended and Restated Articles of Incorporation and
          Bylaws of the Company and taking such additional actions as are
          reasonably requested by such Purchaser in order to effectuate the
          intent of the foregoing.

               The Management Stockholders shall cooperate with the Company in
complying with this Section 8.6, including approving the amendment of the
Company's Restated Articles of Incorporation in a manner reasonably requested by
any Purchaser.

               (b)  In the event any Purchaser has the right to acquire any of
the Company's Securities (as the result of a preemptive offer, pro rata offer or
                                                               --- ----
otherwise), at such Purchaser's request the Company will offer to sell to such
Purchaser non-voting Securities on the same terms as would have existed had such
Purchaser acquired the Securities so offered and immediately requested their
exchange for non-voting Securities pursuant to paragraph (a) above.

               (c)  The Company shall grant to any subsequent holder of
Securities originally acquired by any Purchaser ("Subsequent Purchasers"), upon

substantially similar to this Section 8.6.

               (e)  For purposes of this Section 8.6, a "Regulatory Problem"

means any set of facts or circumstances wherein it has been asserted in writing
by any governmental regulatory agency (or there is a substantial risk of such
assertion) that such Purchaser is not entitled to hold, or exercise any
significant right with respect to, the Securities.

                                                  ----------

securities which are directly or indirectly convertible into, or exercisable or
exchangeable for, such Person's capital stock.  Whenever a reference herein to
Securities is referring to any derivative Securities, the rights of any
Purchaser and Subsequent Purchasers shall apply to such derivative Securities
and all underlying Securities directly

any of the Management Stockholders shall be liable under this Section 7.1 to an
Indemnified Party (a) for any amount paid in settlement of claims without the
Company's consent (which consent shall not be unreasonably withheld), (b) to the
extent that it is finally judicially determined that such Liabilities resulted
primarily from the willful misconduct or gross negligence of such Indemnified
Party or (c) to the extent that it is finally judicially determined that such
Liabilities resulted from the material breach by such Indemnified Party of any
representation, warranty, covenant or other agreement of such Indemnified Party
contained in this Agreement; provided, further, that if and to the extent that
                             --------  -------
such indemnification is unenforceable for any reason, first the Management
Stockholders shall, on a joint and several basis, make the maximum contribution
to the payment and satisfaction of such Liabilities which shall be permissible
under applicable laws and if and to the extent any such Liabilities are still
not fully satisfied, the Company shall thereafter make the maximum contribution
to the payment and satisfaction of such Liabilities which shall be permissible
under applicable laws.  In connection with the obligations of the Company and
the Management Stockholders to indemnify for expenses as set forth above, the
Company and the Management Stockholders further agree, on a joint and several
basis, upon presentation to the Company of appropriate invoices containing
reasonable detail, to reimburse each Indemnified Party for all such expenses
(including, without limitation, reasonable fees, disbursements and other charges
of counsel) as they are incurred by such Indemnified Party; provided, however,
                                                            --------  -------
that, if an Indemnified Party is reimbursed hereunder for any expenses, such
reimbursement of expenses shall be refunded to the extent it is finally judi-
cially determined that the Liabilities in question resulted (a) primarily from
the willful misconduct or gross negligence of such Indemnified Party or (b) from
the material breach by such Indemnified Party of any representation, warranty,
covenant or other agreement of such Indemnified Party contained in this
Agreement.  For the benefit of the Purchasers, the Management Stockholders also
agree to waive all right to contribution from the Company and agree that they
will in no event seek contribution from the Company resulting from or arising
out of the payment and satisfaction of Liabilities hereunder.

          7.2  Notification.  Each Indemnified Party under this Article 7 will,
               ------------
promptly after the receipt of notice of the commencement of any action,
investigation, claim or other proceeding against such Indemnified Party in
respect of which indemnity may be sought from the Company or any of the
Management Stockholders under this Article 7, notify the Company in writing of
the commencement thereof (and the 










             
<PAGE>
                                                                       32




Company shall so notify the Management Stockholders).  The omission of any
Indemnified Party to so notify the Company of any such action shall not relieve
the Company or any of the Management Stockholders from any liability which any
of them may have to such Indemnified Party (a) other than pursuant to this
Article 7 or (b) under this Article 7 unless, and only to the extent that, such
omission results in the forfeiture of substantive rights or defenses.  In case
any such action, claim or other proceeding shall be brought against any
Indemnified Party and it shall notify the Company of the commencement thereof,
the Company (but not any Management Stockholder) shall be entitled to assume the
defense thereof at its own expense, with counsel satisfactory to such Indem-
nified Party in its reasonable judgment; provided, however, that any Indemnified
                                         --------  -------
Party may, at its own expense, retain separate counsel to participate in such
defense.  Notwithstanding the foregoing, in any action, claim or proceeding in
which the Company or any of the Management Stockholders, on the one hand, and an
Indemnified Party, on the other hand, is, or is reasonably likely to become, a
party, such Indemnified Party shall have the right to employ separate counsel at
the Company's expense and to control its own defense of such action, claim or
proceeding if, in the reasonable opinion of counsel to such Indemnified Party, a
conflict or potential conflict exists between the Company or any Management
Stockholder, on the one hand, and such Indemnified Party, on the other hand,
that would make such separate representation advisable.  The Company and the
Management Stockholders each agree that it, she or he, as the case may be, will
not, without the prior written consent of the Purchasers, settle, compromise or
consent to the entry of any judgment in any pending or threatened claim, action
or proceeding relating to the matters contemplated hereby (if any Indemnified
Party is a party thereto or has been actually threatened to be made a party
thereto) unless such settlement, compromise or consent includes an unconditional
release of the Purchasers and each other Indemnified Party from all liability
arising or that may arise out of such claim, action or proceeding.  The Company
and the Management Stockholders shall not be liable for any settlement of any
claim, action or proceeding effected against an Indemnified Party without the
Company's written consent, which consent shall not be unreasonably withheld. 
The rights accorded to Indemnified Parties hereunder shall be in addition to any
rights that any Indemnified Party may have at common law, by separate agreement
or otherwise.

          7.3  Limitations on Indemnification.  Notwithstanding any other
               ------------------------------
provision of this Article 7, the indemnification obligation of the Management
Stockholders and the Company hereunder shall be limited as follows:

                                                                       33





                 (i)  the Management Stockholders and the Company shall not be
     obligated to make any payment for indemnification pursuant to
     Section 7.1(i) hereof until the aggregate amount of indemnification
     payments under this Agreement and the Stock Purchase Agreement (other than
     payments pursuant to Section 7.1(ii) of this Agreement and Section 7.1(ii)
     of the Stock Purchase Agreemnt) exceed $500,000.00 (the "Basket Amount"),
                                                              -------------
     whereupon the Company and the Management Stockholders shall be obligated to
     pay in full all such amounts for indemnification, including the Basket
     Amount, subject to clauses (iii) and (iv) below;

                (ii)  the Management Stockholders and the Company shall not be
     obligated to make any payment for indemnification pursuant to Section
     7.1(ii) hereof until the aggregate amount of indemnification payments under
     this Agreement and the Stock Purchase Agreement (other than payments
     pursuant to Section 7.1(i) of this Agreement Section 7.1(i) of the Stock
     Purchase Agreement) exceed $500,000.00 (the "Insurance Basket Amount"),
                                                  -----------------------
     whereupon the Company shall be obligated to pay in full all such amounts
     for indemnification, including the Insurance Basket Amount, subject to
     clauses (iii) and (iv) below; 

               (iii)  none of the Management Stockholders shall be individually
     obligated to pay any amount for indemnification pursuant to Section 7
     hereof and under the Stock Purchase Agreement in excess of 100% of the
     aggregate payment received by such Management Stockholder from the Company
     pursuant to the Share Redemption Agreement; and

                (iv)  the Company shall not be obligated to pay any amount for
     indemnification pursuant to Section 7 hereof in excess of $10,000,000.00
     plus accrued and unpaid interest on the Senior Subordinated Notes.

the Purchasers at the purchase price thereof plus accrued and unpaid interest on

          8.6.2  Regulatory Compliance Cooperation.
                 ---------------------------------

          (a)  In the event that any Purchaser determines that it has a
Regulatory Problem (as defined below), the Company agrees to take all such
actions as are reasonably requested by such Purchaser in order (i) to effectuate
and facilitate any transfer by such Purchaser of any Securities (as defined
below) of the Company then held by such Purchaser to any Affiliate of the
Purchaser designated by such Purchaser, (ii) to permit such Purchaser (or any
Affiliate of such Purchaser) to exchange all or any portion of the voting
Securities then held by such Person on a share-for-share basis for shares of a
class of nonvoting Securities of the Company, which nonvoting Securities shall
be identical in all respects to such voting Securities, except that such new
Securities shall be nonvoting and shall be convertible into voting Securities on
such terms as are requested by such Purchaser in light of regulatory
considerations then prevailing, and (iii) to continue and preserve the
respective allocation of the voting interests with respect to the Company
provided for in the Stockholders' Agreement and with respect to such Purchaser's
ownership of the Company's voting Securities.  Such actions may include, but
shall not necessarily be limited to:

               (A)  entering into such additional agreements as are requested by
          such Purchaser to permit any Person(s) designated by such Purchaser to
          exercise any voting power which is relinquished by such Purchaser upon
          any exchange of voting Securities for nonvoting Securities of the
          Company; and

               (B)  entering into such additional agreements, adopting such
          amendments to the Amended and Restated Articles of Incorporation and

               The Management Stockholders shall cooperate with the Company in
complying with this Section 8.6, including approving the amendment of the
Company's Restated Articles of Incorporation in a manner reasonably requested by
any Purchaser.

               (b)  In the event any Purchaser has the right to acquire any of
the Company's Securities (as the result of a preemptive offer, pro rata offer or
                                                               --- ----
otherwise), at such Purchaser's request the Company will offer to sell to such
Purchaser non-voting Securities on the same terms as would have existed had such
Purchaser acquired the Securities so offered and immediately requested their
exchange for non-voting Securities pursuant to paragraph (a) above.

               (c)  The Company shall grant to any subsequent holder of
Securities originally acquired by any Purchaser ("Subsequent Purchasers"), upon
                                                  ---------------------

substantially similar to this Section 8.6.

               (e)  For purposes of this Section 8.6, a "Regulatory Problem"

means any set of facts or circumstances wherein it has been asserted in writing
by any governmental regulatory agency (or there is a substantial risk of such
assertion) that such Purchaser is not entitled to hold, or exercise any
significant right with respect to, the Securities.

               (f)  As used in this Section 8.6, "Securities" means with respect
                                                  ----------
to any Person, such Person's capital stock or any options, warrants or other
securities which are directly or indirectly convertible into, or exercisable or
exchangeable for, such Person's capital stock.  Whenever a reference herein to
Securities is referring to any derivative Securities, the rights of any
Purchaser and Subsequent Purchasers shall apply to such derivative Securities
and all underlying Securities directly or indirectly issuable upon conversion,
exchange or exercise of such derivative Securities.

applicable law, any interest that shall accrue on overdue interest on this Note

                    ---------------------------------
any Event of Default under Sections 7(a)(ix) or (x) of this Note: 

                    (i)  Upon any payment or distribution of assets of the
Company to creditors of the Company, holders of Senior Indebtedness shall be
entitled to receive payment in full before the holders of Subordinated
Indebtedness shall be entitled to receive any payment in respect of the
Subordinated Indebtedness, except that the holders of Subordinated Indebtedness

<PAGE>







to receive payments or distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Subordinated
Indebtedness have been applied to the payment of Senior Indebtedness.  A
distribution made under this Section 8 to a holder of Senior Indebtedness which

a payment by the Company on Senior Indebtedness.

                    ---------------
of the holders of the Subordinated Indebtedness and the holders of Senior
Indebtedness.  Nothing in this Section shall:  (i) impair, as between the
Company and the holders of the Subordinated Indebtedness, the obligation of the
Company, which is absolute and unconditional, to pay principal of and interest
(including default interest) on Subordinated Indebtedness in accordance with its
terms; (ii) effect the relative rights of holders of Subordinated Indebtedness
and creditors of the Company other than holders of Senior Indebtedness; or (iii)
prevent the holders of Subordinated Indebtedness from exercising their available
remedies upon a default or Event of Default, subject to the rights, if any,
under this Section 8 of holders of Senior Indebtedness to receive distributions
otherwise payable to the holders of Subordinated Indebtedness.  

               (g)  Subordination May Not Be Impaired by the Company.  No right
                    ------------------------------------------------
of any holder of any Senior Indebtedness to enforce the subordination of the
Subordinated Indebtedness shall be impaired by any failure by the Company to
comply with this Note.

depositing of funds for the defeasance of the Subordinated Indebtedness and any
payment on account of mandatory prepayment or optional prepayment provisions.  

               (i)  Section Not to Prevent Events of Default.  The failure to
                    ----------------------------------------
make a payment on account of principal of or interest on or other amounts
constituting Subordinated Indebtedness by reason of any provision of this
Section 8 shall not be construed as preventing the occurrence of an Event of
Default under Section 7.

Junior Securities shall be made to the holders of the Subordinated Indebtedness

Subordinated Indebtedness shall have received any payment from or distribution
of assets of the Company in respect of the Subordinated Indebtedness in
contravention of the terms of this Section 8 before all Senior Indebtedness is

provisions are hereafter collectively referred to as the "Guarantied
                                                          ----------

requirement that the Purchasers, as a condition of payment by the Guarantor,

Obligations or any other Person, (ii) proceed against or exhaust any security
which may be received from the Company, any other guarantor of the Guarantied
Obligations or any other Person, or (iii) pursue any other remedy whatsoever in
the power of the Purchasers. 

               (b)  Continuing Guaranty.  This Guaranty shall remain in full
                    -------------------
force and effect until all of the Guarantied Obligations have been completely
performed and indefeasibly paid in full, notwithstanding that from time to time
prior thereto the Company may be free from any of the Guarantied Obligations. 
The Guarantor's payment of a portion, but not all, of the Guarantied Obligations
shall in no way limit, affect, modify or abridge the Guarantor's liability for
any portion of the Guarantied Obligations that has not been completely performed
or indefeasibly paid in full.

limitation, impairment, discharge or termination for any reason (other than the
complete performance and the indefeasible payment in full of the Guarantied
Obligations), including, without limitation, the occurrence of any one or more
of the following, whether or not the Guarantor shall have had notice or
knowledge of any of them:

Obligations;

Guarantied Obligations or the taking and holding of any security for the payment
of the Guarantied Obligations, this Guaranty, or any other guaranty of the
Guarantied Obligations or any release, impairment, surrender, exchange,
substitution, compromise, settlement, rescission or subordination thereof;

any time held by the Purchasers in respect of this Guaranty or the Guarantied
Obligations and any direction of the order or manner of sale thereof, or the
exercise of any other right or remedy that the Purchasers may have with respect
to any such security, as the Purchasers in their sole discretion may determine,
including foreclosure on any such security pursuant to one or more judicial or
nonjudicial sales;

                    (vii)  any failure or omission to exercise, assert or

respects more burdensome than that of the principal; 

                    (v)  any benefit of, or any right to participate in, or any
notices of exchange, sale, surrender or other handling of, any security or
collateral which may be given to the Purchasers to secure payment or performance
of the Guarantied Obligations or any other liability of the Company to the
Purchasers; and

                   (vi)  to the fullest extent permitted by law, any other
defenses or benefits that may be derived from or afforded by law which limit the
liability of, or exonerate, guarantors or sureties, or which may conflict with
the terms of this Guaranty, including, without limitation, failure of
consideration, breach of warranty, statute of frauds, statute of limitations,
accord and satisfaction, and usury.

          4.   Bankruptcy and Related Matters.
               ------------------------------

               (a)  No Proceedings Against the Company.  So long as any of the
                    ----------------------------------
Guarantied Obligations remain outstanding, the Guarantor shall not, without the
prior written consent of the Purchasers, commence or join with any other Person
in commencing any bankruptcy, liquidation, reorganization or insolvency
proceedings of, or against, the Company.  

               (b)  Guarantor Remains Obligated.  The obligations of the
                    ---------------------------
Guarantor hereunder shall not be reduced, limited, impaired, discharged,
deferred, suspended or terminated by any proceeding or action, voluntary or
involuntary, involving the bankruptcy, insolvency, receivership, reorganization,
marshalling of assets, assignment for the benefit of creditors, composition with
creditors, readjustment, liquidation or arrangement of the Company or similar
proceedings or actions or by any defense which the Company may have by reason of
the order, decree or decision of any court or administrative body resulting from
any such proceeding or action.  Without limiting the generality of the
foregoing, the Guarantor's liability shall extend to all

                                                                        7





amounts and obligations that constitute the Guarantied Obligations and would be
owed by the Company but for the fact that they are unenforceable or not
allowable due to the existence of any such proceeding or action.

               (c)  Stay of Acceleration.  The Guarantor agrees that, notwith-
                    --------------------
standing anything to the contrary herein, if, after the occurrence and during
the continuance of an Event of Default, the Purchasers are prevented by
applicable law from exercising their rights to accelerate the maturity of the
Guarantied Obligations, to collect any of the Guarantied Obligations or to
enforce or exercise any other right or remedy with respect to the Guarantied
Obligations, the Guarantor shall pay to the Purchasers upon demand therefor the
amount that would otherwise have been due and payable had such rights and
remedies been permitted to be exercised by the Purchasers.

               (d)  Post-Petition Interest.  Pursuant to, and without limiting
                    ----------------------
the foregoing, the Guarantor acknowledges and agrees that any interest on any
portion of the Guarantied Obligations which accrues after the commencement of
any proceeding or action referred to in Section 4(b) (or, if interest on any
portion of the Guarantied Obligations ceases to accrue by operation of law by
reason of the commencement of said proceeding or action, such interest as would
have accrued on such portion of the Guarantied Obligations if said proceedings
or actions had not been commenced) shall be included in the Guarantied
Obligations, it being the intention of the Guarantor and the Purchasers that the
Guarantied Obligations which are guarantied by the Guarantor pursuant to this
Guaranty shall be determined without regard to any rule of law or order which
may relieve the Company of any portion of such Guarantied Obligations.  The
Guarantor will permit any trustee in bankruptcy, receiver, debtor in possession,
assignee for the benefit of creditors or similar person to pay the Purchasers,
or allow the claim of the Purchasers, for the benefit of the Purchasers, in
respect of, any such interest accruing after the date on which such proceeding
is commenced.

               (e)  Reinstatement of Guaranty.  Notwithstanding anything to the
                    -------------------------
contrary contained herein, in the event that all or any portion of the
Guarantied Obligations are paid by the Company, the obligations of the Guarantor
hereunder shall continue and remain in full force and effect or be reinstated,
as the case may be, if all or any part of such payment(s) are rescinded or
recovered, directly or indirectly, from the Purchasers as a preference,
fraudulent transfer or otherwise, and any such payments which are so rescinded
or recovered shall constitute Guarantied Obligations for all purposes under this
Guaranty.

                                                                        8






          5.  No Subrogation.  Notwithstanding any payment or payments made by
              --------------
the Guarantor hereunder, or any set-off or application of funds of the Guarantor
by the Purchasers, the Guarantor hereby irrevocably waives any claim or other
rights that it may now or hereafter acquire against the Company or any other
insider guarantor that arise from the existence, payment, performance or
enforcement of the Guarantor's obligations under this Guaranty, or the Notes,
including, without limitation, any right of subrogation, reimbursement, exoner-
ation, contribution or indemnification and any right to participate in any claim
or remedy of the Purchasers against the Company or any other insider guarantor
or any collateral security, whether or not such claim, remedy or right arises in
equity or under contract, statute or common law, including, without limitation,
the right to take or receive from the Company or any other insider guarantor,
directly or indirectly, in cash or other property or by set-off or in any other
manner, payment or security on account of such claim, remedy or right.  If any
amount shall be paid to the Guarantor in violation of the preceding sentence,
such amount shall be held by the Guarantor in trust for the Purchasers,
segregated from other funds of the Guarantor, and shall, forthwith upon receipt
by the Guarantor, be turned over to the Purchasers in the exact form received by
the Guarantor (duly endorsed by the Guarantor to the Purchasers, if so requested
by the Purchasers), to be applied against the Guarantied Obligations, whether
matured or unmatured, in such order as the Purchasers may determine.

          6.   Limitation on Subsidiary Guaranty.  Notwithstanding Section 2 of
               ---------------------------------
this Guaranty, the liability of the Guarantor under this Guaranty shall not
exceed the sum of ninety-five percent (95%) of the excess of (a) the aggregate
Fair Saleable Value of the assets of such Guarantor as determined at the earlier
of the commencement of a case under Title 11 of the Bankruptcy Code in which the
Guarantor is a debtor and the date enforcement hereunder is sought (the
"Guaranty Date") over (b) the amount of the debts of such Guarantor on the
 -------------
Guaranty Date.

          7.   Subordination of Other Obligations.  The Guarantor hereby agrees
               ----------------------------------
that any indebtedness of the Company now or hereafter held by the Guarantor is
hereby subordinated in right of payment to the Guarantied Obligations, and any
such indebtedness of the Company to the Guarantor collected or received by the
Guarantor after an Event of Default has occurred and is continuing shall be held
in trust for the Purchasers and shall forthwith be paid over to the Purchasers
to be credited and applied against the Guarantied Obligations without in any way
affecting,

impairing or limiting the liability of the Guarantor under this Guaranty.

          8.   Subordination of Guaranty.  Notwithstanding any other provision

Lien under any Contractual Obligation of the Guarantor, or any Requirement of
Law applicable to the Guarantor.

               9.3  Governmental Authorization; Third Party Consents.  No

against, the Guarantor of this Guaranty or the consummation of the transactions
contemplated hereby.

               9.4  Binding Effect.  This Guaranty has been duly executed and
                    --------------
delivered by the Guarantor and constitutes the legal, valid and binding obliga-

to obtain information from the Company on a continuing basis concerning the
financial condition of the Company and the Company's ability to perform its
obligations under the Purchase Agreement and the Notes, and the Guarantor
covenants and agrees to keep informed of the financial condition of the Company

Obligations.  The Guarantor hereby waives and relinquishes any duty on the part
of the Purchasers to disclose any matter, fact or thing relating to the busi-
ness, operations or conditions of the Company, whether now known or hereafter

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

                    (i)  the Company shall default in the payment of the
principal of this Note, when and as the same shall become due and payable,

                   (iv)  the Company shall (a) voluntarily commence any
proceeding or file any petition seeking relief under Title 11 of the United
States Code, as now constituted or hereafter amended, or any other Federal or
state bankruptcy, insolvency, receivership or similar law, (b) consent to the
institution of or the entry of an order for relief against it, or fail to
contest in a timely and appropriate manner, any proceeding or the filing of any
petition described in paragraph (iii) of this Section 5(a), (c) apply for or

principal amount of this Note and the other Notes issued pursuant to the Share
Redemption Agreement, by written notice to the Company, may declare the
principal of and accrued interest on the Notes issued pursuant to the Share
Redemption Agreement to be due and payable immediately.  Upon such declaration,
such principal and interest shall become immediately due and payable.  The
holders of a majority of the aggregate outstanding principal amount of this Note
and the other Notes issued pursuant to the Share Redemption Agreement may
rescind an acceleration and its consequences if all existing Events of Default
have been cured or waived, except nonpayment of principal or interest that has
become due solely because of the acceleration, and if the rescission would not
conflict with any judgment or decree.  Any notice or rescission shall be given
in the manner specified in Section 9 hereof.

or otherwise) shall be made on account of the principal of or interest on this
Note or the other Notes issued pursuant to the Share Redemption Agreement or as
a sinking fund for such Notes or in respect of any redemption, retirement,
purchase or other acquisition of such Notes.

               (d)  Limitation on Remedies.  As long as any Senior Indebtedness
                    ----------------------
remains outstanding, the holder of this Note shall not declare or join in any
declaration of this Note to be due and payable by reason of any Event of Default
or otherwise take any action against the Company (including, without limitation,
commencing any legal action against the Company or filing or joining in the
filing of any insolvency petition against the Company).

               (e)  Subordination Upon Certain Events.  Upon the occurrence of

                    (i)  Upon any payment or distribution of assets of the
Company to creditors of the Company, holders of Senior Indebtedness shall be
entitled to receive payment in full in cash before the holders of Subordinated
Indebtedness shall be entitled to receive any payment in respect of the
Subordinated Indebtedness.

                   (ii)  Until all Senior Indebtedness is paid in full in cash,
any distribution to which the holders of Subordinated Indebtedness would be
entitled but for this Section 6 shall be made to holders of Senior Indebtedness,

               (f)  Payments and Distributions Received.  If the holders of the

Subordinated Indebtedness shall have received any payment from or distribution

be received and held in trust for and shall be paid over or delivered to 






























                                          6





<PAGE>







the holders of Senior Indebtedness (or their authorized agent) to the extent

                    -----------
of Senior Indebtedness are paid in full in cash, the holders of the Subordinated
Indebtedness shall be subrogated to the rights of holders of Senior Indebtedness
to receive payments or distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Subordinated
Indebtedness have been applied to the payment of Senior Indebtedness.  A
distribution made under this Section 6 to a holder of Senior Indebtedness which
otherwise would have been made to the holders of the Subordinated Indebtedness
is not, as between the Company and the holders of the Subordinated Indebtedness,
a payment by the Company on Senior Indebtedness.

               (h)  Relative Rights.  This Section defines the relative rights
                    ---------------
of the holders of the Subordinated Indebtedness and the holders of Senior
Indebtedness.  Nothing in this Section shall:  (i) impair, as between the
Company and the holders of the Subordinated Indebtedness, the obligation of the
Company, which is absolute and unconditional, to pay principal of and interest
on Subordinated Indebtedness in accordance with its terms; or (ii) effect the
relative rights of holders of Subordinated Indebtedness and creditors of the
Company other than holders of Senior Indebtedness.

               (i)  Subordination May Not Be Impaired by the Company.  No right
                    ------------------------------------------------
of any holder of any Senior Indebtedness to enforce the subordination of the
Subordinated Indebtedness shall be impaired by any failure by the Company to
comply with this Note.  

               (j)  Payments.  A payment with respect to principal of or
                    --------
interest on the Subordinated Indebtedness shall include, without limitation,
payment of principal of, and interest on the Subordinated Indebtedness, any
depositing of funds for the defeasance of the Subordinated Indebtedness and any
payment on account of mandatory prepayment or optional prepayment provisions.

                    ----------------------------------------------------
holder of this Note agrees and consents that without notice to or assent by such

compromised, supplemented, terminated, waived or released;

                     (ii)  the holders of Senior Indebtedness, and any
representative or representatives acting on behalf thereof, may exercise or
refrain from exercising any right, remedy or power granted by or in connection
with any agreements relating to the Senior Indebtedness; and

                    (iii)  any balance or balances of funds with any holder of
Senior Indebtedness at any time outstanding to the credit of the Company may,
from time to time, in whole or in part, be surrendered or released;

all as the holders of the Senior Indebtedness, and any representative or
representatives acting on behalf thereof, may deem advisable, and all without
impairing, abridging, diminishing, releasing or affecting the subordination of
the Subordinated Indebtedness to the Senior Indebtedness provided for herein.

               (l)  Modification of Subordination Provisions.  The subordination
                    ----------------------------------------
provisions of this Note are for the benefit of the holders from time to time of
Senior Indebtedness and, so long as any Senior Indebtedness remains unpaid,
these provisions may not be modified, rescinded or canceled in whole or in part
without the prior written consent thereto of the holders of a majority of the
aggregate principal amount outstanding of Senior Subordinated Notes and the
holders of a majority of the aggregate principal amount outstanding of any other
Senior Indebtedness which the Company may from time to time designate as
entitled to the benefits of this Section 5(l).

               (m)  Miscellaneous.

holders of the Senior Indebtedness and (2) all diligence in the collection or
protection of or realization upon the Senior Indebtedness.

                     (ii)  The Company and the holder of this Note hereby
expressly agree that the holders of Senior Indebtedness may enforce any and all
rights derived herein by suit, either in equity or law, for specific performance
of any agreement contained in these subordination provisions 































                                          8





<PAGE>







or for judgment at law and any other relief whatsoever appropriate to such
action or procedure.

                    (iii)  The holder of this Note acknowledges and agrees that
the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of Senior Indebtedness, whether
such Senior Indebtedness was created or acquired before or after the issuance of
this Note, and each holder of Senior Indebtedness shall be deemed conclusively
to have relied upon such subordination provisions in acquiring and continuing to
hold the Senior Indebtedness held by such holder, as the case may be.

9 of this Note.

                    (b)  Payment of Interest.  When all or any portion of this
                         -------------------
Note is converted, all interest accrued and unpaid (whether or not currently

converted and the right to receive cash in accordance with Section 7.1(b) in
respect of accrued and unpaid interest, if any, on the portion of this Note so
converted; and the portion of this Note so converted shall no longer be deemed
to be outstanding, whether or not this Note has been surrendered to the Company
for conversion.

               7.2  Adjustment of Conversion Price.  If the Company shall, at
                    ------------------------------
any time or from time to time, (a) declare a dividend on the Company Stock
payable in shares of its capital stock (including Company Stock), (ii) subdivide
the outstanding Company Stock, (iii) combine the outstanding Company Stock into
a smaller number of shares, or (iv) issue any shares of its capital stock in a
reclassification of the Company Stock (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
corporation), then in each such case, the Conversion Price in effect at the time
of the record date for such dividend or of the effective date of such
subdivision, combination or reclassification shall be adjusted to that price
which will permit the number of shares of Class A Common Stock into which this
Note may be 
































                                          10





<PAGE>







converted to be increased or reduced in the same proportion as the number of
shares of Company Stock are increased or reduced in connection with such
dividend, subdivision, combination or reclassification.  Any such adjustment
shall become effective immediately after the record date of such dividend or the
effective date of such subdivision, combination or reclassification.  Such
adjustment shall be made successively whenever any event listed above shall
occur.  If a dividend is declared and such dividend is not paid, the Conversion
Price shall again be adjusted to be the Conversion Price in effect immediately
prior to such record date.

               7.3  De Minimis Adjustments.  No adjustment in the Conversion
                    ----------------------
Price shall be made if the amount of such adjustment would result in a change in
the Conversion Price per share of less than $.02, but in such case any adjust-
ment that would otherwise be required to be made shall be carried forward and
shall be made at the time of and together with the next subsequent adjustment,
which together with any adjustment so carried forward, would result in a change
in the Conversion Price of $.05 per share.  If the Company shall, at any time or
from time to time, issue Company Stock by way of dividends on any stock of the
Company or subdivide or combine the outstanding shares of the Company Stock,
such amounts of $.02 and $.05 (as theretofore increased or decreased, if such
amounts shall have been adjusted in accordance with the provisions of this
clause) shall forthwith be proportionately increased in the case of a combina-
tion or decreased in the case of a subdivision or stock dividend so as appro-
priately to reflect the same.  Notwithstanding the provisions of the first
sentence of this Section 7.3, any adjustment postponed pursuant to this
Section 7.3 shall be made no later than the earlier of (i) three years from the
date of the transaction that would, but for the provisions of the first sentence
of this Section 7.3, have required such adjustment, (ii) a Conversion Date or
(iii) the Maturity Date.

               7.4  Reorganization, Reclassification, Merger and Sale of Assets.
                    -----------------------------------------------------------
If there occurs any capital reorganization or any reclassification of the
Company Stock, the consolidation or merger of the Company with or into another
Person (other than a merger or consolidation of the Company in which the Company
is the continuing corporation and which does not result in any reclassification
or change of outstanding shares of Company Stock) or the sale or conveyance of
all or substantially all of the assets of the Company to another Person, then
the holder of this Note will thereafter be entitled to receive, upon the
conversion of this Note in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable 































                                          11





<PAGE>







to the holders of outstanding Company Stock upon such reorganization,
reclassification, consolidation, merger, sale or conveyance, in respect of that
number of shares of Class A Common Stock into which this Note might have been
converted immediately prior to such reorganization, reclassification, consolida-
tion, merger, sale or conveyance; and, in any such case, appropriate adjustments
(as determined in good faith by the Board of Directors of the Company) shall be
made to assure that the provisions hereof (including provisions with respect to
changes in, and other adjustments of, the Conversion Price) shall thereafter be
applicable, as nearly as reasonably may be practicable, in relation to any
securities or other assets thereafter deliverable upon conversion of this Note.

               7.5  Certificate as to Adjustments.  Whenever the Conversion
                    -----------------------------
Price or the securities or other property deliverable upon the conversion of
this Note shall be adjusted pursuant to the provisions hereof, the Company shall
promptly give written notice thereof to the holder of this Note, in the manner
specified in Section 9 of this Note, stating the adjusted Conversion Price and
the securities or other property deliverable upon conversion of this Note calcu-
lated to the nearest cent or the nearest one-hundredth of a share and setting
forth in reasonable detail the method of calculation and the facts requiring
such adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

               7.6  Fractional Shares.  Notwithstanding any other provision of
                    -----------------
this Note, the Company shall not be required to issue fractions of shares upon
conversion of this Note or to distribute certificates which evidence fractional
shares.  In lieu of fractional shares, the Company may make payment to the
holder of this Note, at the time of conversion of this Note as herein provided,
of an amount in cash equal to such fraction multiplied by the Conversion Price.

               7.7  No Rights or Liability as a Stockholder.  This Note does not
                    ---------------------------------------
entitle the holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Company to convert this Note into shares of Class A Common Stock, and no
enumeration herein of the rights or privileges of the holder of this Note, shall
give rise to any liability to such holder as a stockholder of the Company.

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

                    (i)  the Company shall default in the payment of the
principal of this Note, when and as the same shall become due and payable,
whether at maturity or at a date fixed for prepayment or by acceleration or

under Title 11 of the United States Code, as now constituted or hereafter
amended, or any other Federal or state bankruptcy, insolvency, receivership or
similar law, (b) consent to the institution of or the entry of an order for
relief against it, or fail to contest in a timely and appropriate manner, any
proceeding or the filing of any petition described in paragraph (iii) of this

and payable, without presentment, demand, protest or notice of any kind, all of
which are expressly waived.  If any other Event of Default occurs and is
continuing, the holders of at least a majority of the aggregate outstanding
principal amount of this Note and the other Notes issued pursuant to the Share
Redemption Agreement, by written notice to the Company, may declare the
principal of and accrued interest on the Notes issued pursuant to the Share
Redemption Agreement to be due and payable immediately.  Upon such declaration,
such principal and interest shall become immediately due and payable.  The
holders of a majority of the aggregate outstanding principal amount of this Note
and the other Notes issued pursuant to the Share Redemption Agreement may
rescind an acceleration and its consequences if all existing Events of Default
have been cured or waived, except nonpayment of principal or interest that has
become due solely because of the acceleration, and if the rescission would not
conflict with any judgment or decree.  Any notice or rescission shall be given
in the manner specified in Section 9 hereof.

          6.   Subordination.  This Note and the other Notes issued pursuant to

          "Senior Indebtedness" shall mean (i) the principal of and interest on
           -------------------
(including without limitation any interest that accrues after the commencement
of any case, proceeding or other legal action relating to the bankruptcy,

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

or otherwise) shall be made on account of the principal of or interest on this
Note or the other Notes issued pursuant to the Share Redemption Agreement or as
a sinking fund for such Notes or in respect of any redemption, retirement,
purchase or other acquisition of such Notes.

               (d)  Limitation on Remedies.  As long as any Senior Indebtedness
                    ----------------------
remains outstanding, the holder of this Note shall not declare or join in any
declaration of this Note to be due and payable by reason of any Event of Default
or otherwise take any action against the Company (including, without limitation,
commencing any legal action against the Company or filing or joining in the
filing of any insolvency petition against the Company).

               (e)  Subordination Upon Certain Events.  Upon the occurrence of
                    ---------------------------------
any Event of Default under Sections 5(a)(iii) or (iv) of this Note:

                    (i)  Upon any payment or distribution of assets of the
Company to creditors of the Company, holders of Senior Indebtedness shall be
entitled to receive payment in full in cash before the holders of Subordinated
Indebtedness shall be entitled to receive any payment in respect of the
Subordinated Indebtedness.

                   (ii)  Until all Senior Indebtedness is paid in full in cash,
any distribution to which the holders of Subordinated Indebtedness would be
entitled but for this Section 6 shall be made to holders of Senior Indebtedness,
as their interests may appear.

Subordinated Indebtedness shall have received any payment from or distribution
of assets of the Company in respect of the Subordinated Indebtedness in
contravention of the terms of this Section 6 before all Senior Indebtedness is
paid in full in cash, then and in such event such payment or distribution shall
be received and held in trust for and shall be paid over or delivered to the
holders of Senior Indebtedness (or their authorized agent) to the extent
necessary to pay all such Senior Indebtedness in full in cash.

<PAGE>








               (g)  Subrogation.  After all amounts payable under or in respect
                    -----------
of Senior Indebtedness are paid in full in cash, the holders of the Subordinated
Indebtedness shall be subrogated to the rights of holders of Senior Indebtedness
to receive payments or distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Subordinated
Indebtedness have been applied to the payment of Senior Indebtedness.  A
distribution made under this Section 6 to a holder of Senior Indebtedness which
otherwise would have been made to the holders of the Subordinated Indebtedness
is not, as between the Company and the holders of the Subordinated Indebtedness,
a payment by the Company on Senior Indebtedness.

               (h)  Relative Rights.  This Section defines the relative rights
                    ---------------
of the holders of the Subordinated Indebtedness and the holders of Senior
Indebtedness.  Nothing in this Section shall:  (i) impair, as between the
Company and the holders of the Subordinated Indebtedness, the obligation of the
Company, which is absolute and unconditional, to pay principal of and interest
on Subordinated Indebtedness in accordance with its terms; or (ii) effect the
relative rights of holders of Subordinated Indebtedness and creditors of the
Company other than holders of Senior Indebtedness.

               (i)  Subordination May Not Be Impaired by the Company.  No right
                    ------------------------------------------------
of any holder of any Senior Indebtedness to enforce the subordination of the
Subordinated Indebtedness shall be impaired by any failure by the Company to
comply with this Note.  

               (j)  Payments.  A payment with respect to principal of or
                    --------
interest on the Subordinated Indebtedness shall include, without limitation,
payment of principal of, and interest on the Subordinated Indebtedness, any
depositing of funds for the defeasance of the Subordinated Indebtedness and any
payment on account of mandatory prepayment or optional prepayment provisions.  

               (k)  Subordination Not Impaired; Benefit of Subordination.  The
                    ----------------------------------------------------
holder of this Note agrees and consents that without notice to or assent by such
holder, and without affecting the liabilities and obligations of the Company and
such holder and the rights and benefits of the holders of the Senior
Indebtedness set forth herein:

                      (i)  the obligations and liabilities of the Company and
any other party or parties for or upon the Senior Indebtedness may, from time to
time, be increased, renewed, refinanced, extended, modified, amended, 































                                          7

restated, compromised, supplemented, terminated, waived or released;

                     (ii)  the holders of Senior Indebtedness, and any
representative or representatives acting on behalf thereof, may exercise or
refrain from exercising any right, remedy or power granted by or in connection
with any agreements relating to the Senior Indebtedness; and

                    (iii)  any balance or balances of funds with any holder of
Senior Indebtedness at any time outstanding to the credit of the Company may,
from time to time, in whole or in part, be surrendered or released;

all as the holders of the Senior Indebtedness, and any representative or
representatives acting on behalf thereof, may deem advisable, and all without
impairing, abridging, diminishing, releasing or affecting the subordination of
the Subordinated Indebtedness to the Senior Indebtedness provided for herein.

               (l)  Modification of Subordination Provisions.  The subordination
                    ----------------------------------------
provisions of this Note are for the benefit of the holders from time to time of
Senior Indebtedness and, so long as any Senior Indebtedness remains unpaid,
these provisions may not be modified, rescinded or canceled in whole or in part
without the prior written consent thereto of the holders of a majority of the
aggregate principal amount outstanding of Senior Subordinated Notes and the
holders of a majority of the aggregate principal amount outstanding of any other
Senior Indebtedness which the Company may from time to time designate as
entitled to the benefits of this Section 5(l).

               (m)  Miscellaneous.
                    -------------

                      (i)  To the extent permitted by applicable law, the holder
of this Note and the Company hereby waive (1) notice of acceptance hereof by the
holders of the Senior Indebtedness and (2) all diligence in the collection or
protection of or realization upon the Senior Indebtedness.

                     (ii)  The Company and the holder of this Note hereby
expressly agree that the holders of Senior Indebtedness may enforce any and all
rights derived herein by suit, either in equity or law, for specific performance
of any agreement contained in these subordination provisions or for judgment at
law and any other relief whatsoever appropriate to such action or procedure.

                    (iii)  The holder of this Note acknowledges and agrees that
the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of Senior Indebtedness, whether
such Senior Indebtedness was created or acquired before or after the issuance of
this Note, and each holder of Senior Indebtedness shall be deemed conclusively
to have relied upon such subordination provisions in acquiring and continuing to
hold the Senior Indebtedness held by such holder, as the case may be.

as provided below, the Company may, subject to the terms and conditions of this
Section 7, convert this Note, in whole or in part, into fully paid and

then being converted and (y) the Conversion Price.  The Company may convert this
Note (or a portion of the outstanding principal amount of this Note) by giving
written notice (a "Conversion Notice") of such mandatory conversion to the
                   -----------------
holder of this Note, at least five Business Days prior to the date fixed for
such conversion.  Such notice shall be given in the manner specified in Section
9 of this Note.

                    (b)  Payment of Interest.  When all or any portion of this
                         -------------------
Note is converted, all interest accrued and unpaid (whether or not currently
payable) to the date of such conversion on the portion of this Note converted
shall be immediately due and payable in cash, which payment shall accompany the
shares of Class A Common Stock issued upon such conversion.

                    (c)  Delivery of Shares and New Notes.  As soon as
                         --------------------------------
practicable after conversion of this Note (or a portion of the outstanding
principal amount of this Note) pursuant to Section 7.1(a), the Company shall
promptly (x) issue and deliver to the holder of this Note a certificate or
certificates for the number of shares of Class A Common Stock set forth in the
Conversion Notice, in such name or names as may be designated by such holder,
along with a check for the amount of cash to be paid in accordance with
Section 7.1(b) in respect of accrued and unpaid interest, if any, on the portion
of this Note then being 






























                                          9





<PAGE>







converted, against delivery to the Company of this Note accompanied by proper
instruments of transfer and (y) cancel this Note upon surrender hereof and, if
this Note is being converted in part only, execute and deliver a new Note in
replacement of the Note surrendered.  The new Note issued by the Company
pursuant to clause (y) of the preceding sentence shall be the same as the Note
submitted for conversion except that (1) it will be dated the date that the Note
submitted for conversion is cancelled and (2) it will be issued in the principal
amount of the unconverted portion of the Note submitted for conversion.

                    (d)  When Conversion Effective.  The conversion of this Note
                         -------------------------
shall be deemed to have been effective on the date fixed by the Company for such
conversion in the Conversion Notice (the "Conversion Date"), whether or not this
                                          ---------------
Note is actually surrendered for conversion, and the Person in whose name any
certificate for shares of Class A Common Stock shall be issuable upon such
conversion, as provided in Section 7.1(c), shall be deemed to be the record
holder of such shares of Class A Common Stock for all purposes on the Conversion
Date.  On and after the Conversion Date, all rights of the holder of this Note
with respect to the portion of this Note converted into shares of Class A Common
Stock, shall cease and terminate, except the right to receive a certificate for
shares of Class A Common Stock with respect to the portion of this Note so
converted and the right to receive cash in accordance with Section 7.1(b) in
respect of accrued and unpaid interest, if any, on the portion of this Note so
converted; and the portion of this Note so converted shall no longer be deemed
to be outstanding, whether or not this Note has been surrendered to the Company
for conversion.

               7.2  Adjustment of Conversion Price.  If the Company shall, at
                    ------------------------------
any time or from time to time, (a) declare a dividend on the Company Stock
payable in shares of its capital stock (including Company Stock), (ii) subdivide
the outstanding Company Stock, (iii) combine the outstanding Company Stock into
a smaller number of shares, or (iv) issue any shares of its capital stock in a
reclassification of the Company Stock (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
corporation), then in each such case, the Conversion Price in effect at the time
of the record date for such dividend or of the effective date of such
subdivision, combination or reclassification shall be adjusted to that price
which will permit the number of shares of Class A Common Stock into which this
Note may be converted to be increased or reduced in the same proportion as the
number of shares of Company Stock are increased or reduced in connection with
such dividend, subdivision, 
































                                          10

combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Conversion Price shall again be
adjusted to be the Conversion Price in effect immediately prior to such record
date.

               7.3  De Minimis Adjustments.  No adjustment in the Conversion
                    ----------------------
Price shall be made if the amount of such adjustment would result in a change in
the Conversion Price per share of less than $.02, but in such case any adjust-
ment that would otherwise be required to be made shall be carried forward and
shall be made at the time of and together with the next subsequent adjustment,
which together with any adjustment so carried forward, would result in a change
in the Conversion Price of $.05 per share.  If the Company shall, at any time or
from time to time, issue Company Stock by way of dividends on any stock of the
Company or subdivide or combine the outstanding shares of the Company Stock,
such amounts of $.02 and $.05 (as theretofore increased or decreased, if such
amounts shall have been adjusted in accordance with the provisions of this
clause) shall forthwith be proportionately increased in the case of a combina-
tion or decreased in the case of a subdivision or stock dividend so as appro-
priately to reflect the same.  Notwithstanding the provisions of the first
sentence of this Section 7.3, any adjustment postponed pursuant to this
Section 7.3 shall be made no later than the earlier of (i) three years from the
date of the transaction that would, but for the provisions of the first sentence
of this Section 7.3, have required such adjustment, (ii) a Conversion Date or
(iii) the Maturity Date.

               7.4  Reorganization, Reclassification, Merger and Sale of Assets.
                    -----------------------------------------------------------
If there occurs any capital reorganization or any reclassification of the
Company Stock, the consolidation or merger of the Company with or into another
Person (other than a merger or consolidation of the Company in which the Company
is the continuing corporation and which does not result in any reclassification
or change of outstanding shares of Company Stock) or the sale or conveyance of
all or substantially all of the assets of the Company to another Person, then
the holder of this Note will thereafter be entitled to receive, upon the
conversion of this Note in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Company Stock
upon such reorganization, reclassification, consolidation, merger, sale or
conveyance, in respect of that number of shares of 































                                          11





<PAGE>







Class A Common Stock into which this Note might have been converted immediately
prior to such reorganization, reclassification, consolidation, merger, sale or
conveyance; and, in any such case, appropriate adjustments (as determined in
good faith by the Board of Directors of the Company) shall be made to assure
that the provisions hereof (including provisions with respect to changes in, and
other adjustments of, the Conversion Price) shall thereafter be applicable, as
nearly as reasonably may be practicable, in relation to any securities or other
assets thereafter deliverable upon conversion of this Note.

               7.5  Certificate as to Adjustments.  Whenever the Conversion
                    -----------------------------
Price or the securities or other property deliverable upon the conversion of
this Note shall be adjusted pursuant to the provisions hereof, the Company shall
promptly give written notice thereof to the holder of this Note, in the manner
specified in Section 9 of this Note, stating the adjusted Conversion Price and
the securities or other property deliverable upon conversion of this Note calcu-
lated to the nearest cent or the nearest one-hundredth of a share and setting
forth in reasonable detail the method of calculation and the facts requiring
such adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

               7.6  Fractional Shares.  Notwithstanding any other provision of
                    -----------------
this Note, the Company shall not be required to issue fractions of shares upon
conversion of this Note or to distribute certificates which evidence fractional
shares.  In lieu of fractional shares, the Company may make payment to the
holder of this Note, at the time of conversion of this Note as herein provided,
of an amount in cash equal to such fraction multiplied by the Conversion Price.

               7.7  No Rights or Liability as a Stockholder.  This Note does not
                    ---------------------------------------
entitle the holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Company to convert this Note into shares of Class A Common Stock, and no
enumeration herein of the rights or privileges of the holder of this Note, shall
give rise to any liability to such holder as a stockholder of the Company.

          5.   Defaults and Remedies.  
               ---------------------

               (a)  Events of Default.  An "Event of Default" shall occur if:
                    -----------------

                    (i)  the Company shall default in the payment of the
principal of this Note, when and as the same shall become due and payable,
whether at maturity or at a date fixed for prepayment or by acceleration or
otherwise and such default shall continue for a period of ten days; or

                   (ii)  the Company shall default in the payment of any

same shall become due and payable and such default shall continue for a period
of 20 days; or

proceeding or file any petition seeking relief 





























                                          3





<PAGE>







under Title 11 of the United States Code, as now constituted or hereafter
amended, or any other Federal or state bankruptcy, insolvency, receivership or
similar law, (b) consent to the institution of or the entry of an order for
relief against it, or fail to contest in a timely and appropriate manner, any
proceeding or the filing of any petition described in paragraph (iii) of this
Section 5(a), (c) apply for or consent to the appointment of a receiver,

clauses (a)(iii) or (iv) of this Section 5, then the outstanding principal of
and all accrued interest on this Note shall automatically become immediately due
and payable, without presentment, demand, protest or notice of any kind, all of
which are expressly waived.  If any other Event of Default occurs and is
continuing, the holders of at least a majority of the aggregate outstanding
principal amount of this Note and the other Notes issued pursuant to the Share
Redemption Agreement, by written notice to the Company, may declare the
principal of and accrued interest on the Notes issued pursuant to the Share
Redemption Agreement to be due and payable immediately.  Upon such declaration,
such principal and interest shall become immediately due and payable.  The
holders of a majority of the aggregate outstanding principal amount of this Note
and the other Notes issued pursuant to the Share Redemption Agreement may
rescind an acceleration and its consequences if all existing Events of Default
have been cured or waived, except nonpayment of principal or interest that has
become due solely because of the acceleration, and if the rescission would not
conflict with any judgment or decree.  Any notice or rescission shall be given
in the manner specified in Section 9 hereof.

          6.   Subordination.  This Note and the other Notes issued pursuant to
               -------------
the Share Redemption Agreement shall at all times be wholly subordinate and

stated maturity.

          "Senior Indebtedness" shall mean (i) the principal of and interest on
           -------------------
(including without limitation any interest that accrues after the commencement
of any case, proceeding or other legal action relating to the bankruptcy,

monetary obligation of the Company arising out of or in connection with the
Senior Subordinated Notes or the Subordinated Note and Stock Purchase Agreement
and (iii) any indebtedness for borrowed money of the Company, whether

guaranteed by the Company, unless the instrument creating or evidencing the same

          "Subordinated Indebtedness" shall mean (i) the principal of and
           -------------------------
interest on this Note and the other Notes issued pursuant to the Share
Redemption Agreement; and (ii) any other monetary obligations of the Company
arising out of or in connection with the Share Redemption Agreement or such

                                          5

shall have occurred shall have been paid in full or duly provided for in a
manner satisfactory to the holders of the Senior Indebtedness, as the case may
be, no direct or indirect payment (in cash, property, securities or by set-off
or otherwise) shall be made on account of the principal of or interest on this
Note or the other Notes issued pursuant to the Share Redemption Agreement or as
a sinking fund for such Notes or in respect of any redemption, retirement,
purchase or other acquisition of such Notes.

               (d)  Limitation on Remedies.  As long as any Senior Indebtedness
                    ----------------------
remains outstanding, the holder of this Note shall not declare or join in any
declaration of this Note to be due and payable by reason of any Event of Default
or otherwise take any action against the Company (including, without limitation,
commencing any legal action against the Company or filing or joining in the
filing of any insolvency petition against the Company).

               (e)  Subordination Upon Certain Events.  Upon the occurrence of
                    ---------------------------------
any Event of Default under Sections 5(a)(iii) or (iv) of this Note:

                    (i)  Upon any payment or distribution of assets of the
Company to creditors of the Company, holders of Senior Indebtedness shall be
entitled to receive payment in full in cash before the holders of Subordinated
Indebtedness shall be entitled to receive any payment in respect of the
Subordinated Indebtedness.

                   (ii)  Until all Senior Indebtedness is paid in full in cash,
any distribution to which the holders of Subordinated Indebtedness would be
entitled but for this Section 6 shall be made to holders of Senior Indebtedness,
as their interests may appear.

                  (iii)  For purposes of this Section 6, a distribution may
consist of cash, securities or other property, by set-off or otherwise.

               (f)  Payments and Distributions Received.  If the holders of the
                    -----------------------------------
Subordinated Indebtedness shall have received any payment from or distribution
of assets of the Company in respect of the Subordinated Indebtedness in
contravention of the terms of this Section 6 before all Senior Indebtedness is
paid in full in cash, then and in such event such payment or distribution shall
be received and held in trust for and shall be paid over or delivered to the
holders of Senior Indebtedness (or their authorized agent) to the extent
necessary to pay all such Senior Indebtedness in full in cash.

<PAGE>








               (g)  Subrogation.  After all amounts payable under or in respect
                    -----------
of Senior Indebtedness are paid in full in cash, the holders of the Subordinated
Indebtedness shall be subrogated to the rights of holders of Senior Indebtedness
to receive payments or distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Subordinated
Indebtedness have been applied to the payment of Senior Indebtedness.  A
distribution made under this Section 6 to a holder of Senior Indebtedness which
otherwise would have been made to the holders of the Subordinated Indebtedness
is not, as between the Company and the holders of the Subordinated Indebtedness,
a payment by the Company on Senior Indebtedness.

               (h)  Relative Rights.  This Section defines the relative rights
                    ---------------
of the holders of the Subordinated Indebtedness and the holders of Senior
Indebtedness.  Nothing in this Section shall:  (i) impair, as between the
Company and the holders of the Subordinated Indebtedness, the obligation of the
Company, which is absolute and unconditional, to pay principal of and interest
on Subordinated Indebtedness in accordance with its terms; or (ii) effect the
relative rights of holders of Subordinated Indebtedness and creditors of the
Company other than holders of Senior Indebtedness.

               (i)  Subordination May Not Be Impaired by the Company.  No right
                    ------------------------------------------------
of any holder of any Senior Indebtedness to enforce the subordination of the
Subordinated Indebtedness shall be impaired by any failure by the Company to
comply with this Note.  

               (j)  Payments.  A payment with respect to principal of or
                    --------
interest on the Subordinated Indebtedness shall include, without limitation,
payment of principal of, and interest on the Subordinated Indebtedness, any
depositing of funds for the defeasance of the Subordinated Indebtedness and any
payment on account of mandatory prepayment or optional prepayment provisions.  

               (k)  Subordination Not Impaired; Benefit of Subordination.  The
                    ----------------------------------------------------
holder of this Note agrees and consents that without notice to or assent by such
holder, and without affecting the liabilities and obligations of the Company and
such holder and the rights and benefits of the holders of the Senior
Indebtedness set forth herein:

                      (i)  the obligations and liabilities of the Company and
any other party or parties for or upon the Senior Indebtedness may, from time to
time, be increased, renewed, refinanced, extended, modified, amended, 































                                          7





<PAGE>







restated, compromised, supplemented, terminated, waived or released;

                     (ii)  the holders of Senior Indebtedness, and any
representative or representatives acting on behalf thereof, may exercise or
refrain from exercising any right, remedy or power granted by or in connection
with any agreements relating to the Senior Indebtedness; and

                    (iii)  any balance or balances of funds with any holder of
Senior Indebtedness at any time outstanding to the credit of the Company may,
from time to time, in whole or in part, be surrendered or released;

all as the holders of the Senior Indebtedness, and any representative or
representatives acting on behalf thereof, may deem advisable, and all without
impairing, abridging, diminishing, releasing or affecting the subordination of
the Subordinated Indebtedness to the Senior Indebtedness provided for herein.

               (l)  Modification of Subordination Provisions.  The subordination
                    ----------------------------------------
provisions of this Note are for the benefit of the holders from time to time of
Senior Indebtedness and, so long as any Senior Indebtedness remains unpaid,
these provisions may not be modified, rescinded or canceled in whole or in part
without the prior written consent thereto of the holders of a majority of the
aggregate principal amount outstanding of Senior Subordinated Notes and the
holders of a majority of the aggregate principal amount outstanding of any other
Senior Indebtedness which the Company may from time to time designate as
entitled to the benefits of this Section 5(l).

               (m)  Miscellaneous.
                    -------------

                      (i)  To the extent permitted by applicable law, the holder
of this Note and the Company hereby waive (1) notice of acceptance hereof by the
holders of the Senior Indebtedness and (2) all diligence in the collection or
protection of or realization upon the Senior Indebtedness.

                     (ii)  The Company and the holder of this Note hereby
expressly agree that the holders of Senior Indebtedness may enforce any and all
rights derived herein by suit, either in equity or law, for specific performance
of any agreement contained in these subordination provisions or for judgment at
law and any other relief whatsoever appropriate to such action or procedure.

<PAGE>








                    (iii)  The holder of this Note acknowledges and agrees that
the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of Senior Indebtedness, whether
such Senior Indebtedness was created or acquired before or after the issuance of
this Note, and each holder of Senior Indebtedness shall be deemed conclusively
to have relied upon such subordination provisions in acquiring and continuing to
hold the Senior Indebtedness held by such holder, as the case may be.

          7.   Conversion.
               ----------

               7.1  Company Right to Require Conversion.
                    -----------------------------------

                    (a)  Conversion.  At any time or from time to time after the
                         ----------
occurrence of a Trigger Event and upon notice given to the holder of this Note
as provided below, the Company may, subject to the terms and conditions of this
Section 7, convert this Note, in whole or in part, into fully paid and
nonassessable shares of Class A Common Stock at the Conversion Price.  The
number of shares of Class A Common Stock to be issued upon conversion of this
Note shall be equal to the quotient of (x) the principal amount of this Note
then being converted and (y) the Conversion Price.  The Company may convert this
Note (or a portion of the outstanding principal amount of this Note) by giving
written notice (a "Conversion Notice") of such mandatory conversion to the
                   -----------------
holder of this Note, at least five Business Days prior to the date fixed for
such conversion.  Such notice shall be given in the manner specified in Section
9 of this Note.

                    (b)  Payment of Interest.  When all or any portion of this
                         -------------------
Note is converted, all interest accrued and unpaid (whether or not currently
payable) to the date of such conversion on the portion of this Note converted
shall be immediately due and payable in cash, which payment shall accompany the
shares of Class A Common Stock issued upon such conversion.

                    (c)  Delivery of Shares and New Notes.  As soon as
                         --------------------------------
practicable after conversion of this Note (or a portion of the outstanding
principal amount of this Note) pursuant to Section 7.1(a), the Company shall
promptly (x) issue and deliver to the holder of this Note a certificate or
certificates for the number of shares of Class A Common Stock set forth in the
Conversion Notice, in such name or names as may be designated by such holder,
along with a check for the amount of cash to be paid in accordance with
Section 7.1(b) in respect of accrued and unpaid interest, if any, on the portion
of this Note then being 






























                                          9





<PAGE>







converted, against delivery to the Company of this Note accompanied by proper
instruments of transfer and (y) cancel this Note upon surrender hereof and, if
this Note is being converted in part only, execute and deliver a new Note in
replacement of the Note surrendered.  The new Note issued by the Company
pursuant to clause (y) of the preceding sentence shall be the same as the Note
submitted for conversion except that (1) it will be dated the date that the Note
submitted for conversion is cancelled and (2) it will be issued in the principal
amount of the unconverted portion of the Note submitted for conversion.

                    (d)  When Conversion Effective.  The conversion of this Note
                         -------------------------
shall be deemed to have been effective on the date fixed by the Company for such
conversion in the Conversion Notice (the "Conversion Date"), whether or not this
                                          ---------------
Note is actually surrendered for conversion, and the Person in whose name any
certificate for shares of Class A Common Stock shall be issuable upon such
conversion, as provided in Section 7.1(c), shall be deemed to be the record
holder of such shares of Class A Common Stock for all purposes on the Conversion
Date.  On and after the Conversion Date, all rights of the holder of this Note
with respect to the portion of this Note converted into shares of Class A Common
Stock, shall cease and terminate, except the right to receive a certificate for
shares of Class A Common Stock with respect to the portion of this Note so
converted and the right to receive cash in accordance with Section 7.1(b) in
respect of accrued and unpaid interest, if any, on the portion of this Note so
converted; and the portion of this Note so converted shall no longer be deemed
to be outstanding, whether or not this Note has been surrendered to the Company
for conversion.

               7.2  Adjustment of Conversion Price.  If the Company shall, at
                    ------------------------------
any time or from time to time, (a) declare a dividend on the Company Stock
payable in shares of its capital stock (including Company Stock), (ii) subdivide
the outstanding Company Stock, (iii) combine the outstanding Company Stock into
a smaller number of shares, or (iv) issue any shares of its capital stock in a
reclassification of the Company Stock (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
corporation), then in each such case, the Conversion Price in effect at the time
of the record date for such dividend or of the effective date of such
subdivision, combination or reclassification shall be adjusted to that price
which will permit the number of shares of Class A Common Stock into which this
Note may be converted to be increased or reduced in the same proportion as the
number of shares of Company Stock are increased or reduced in connection with
such dividend, subdivision, 
































                                          10





<PAGE>







combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Conversion Price shall again be
adjusted to be the Conversion Price in effect immediately prior to such record
date.

               7.3  De Minimis Adjustments.  No adjustment in the Conversion
                    ----------------------
Price shall be made if the amount of such adjustment would result in a change in
the Conversion Price per share of less than $.02, but in such case any adjust-
ment that would otherwise be required to be made shall be carried forward and
shall be made at the time of and together with the next subsequent adjustment,
which together with any adjustment so carried forward, would result in a change
in the Conversion Price of $.05 per share.  If the Company shall, at any time or
from time to time, issue Company Stock by way of dividends on any stock of the
Company or subdivide or combine the outstanding shares of the Company Stock,
such amounts of $.02 and $.05 (as theretofore increased or decreased, if such
amounts shall have been adjusted in accordance with the provisions of this
clause) shall forthwith be proportionately increased in the case of a combina-
tion or decreased in the case of a subdivision or stock dividend so as appro-
priately to reflect the same.  Notwithstanding the provisions of the first
sentence of this Section 7.3, any adjustment postponed pursuant to this
Section 7.3 shall be made no later than the earlier of (i) three years from the
date of the transaction that would, but for the provisions of the first sentence
of this Section 7.3, have required such adjustment, (ii) a Conversion Date or
(iii) the Maturity Date.

               7.4  Reorganization, Reclassification, Merger and Sale of Assets.
                    -----------------------------------------------------------
If there occurs any capital reorganization or any reclassification of the
Company Stock, the consolidation or merger of the Company with or into another
Person (other than a merger or consolidation of the Company in which the Company
is the continuing corporation and which does not result in any reclassification
or change of outstanding shares of Company Stock) or the sale or conveyance of
all or substantially all of the assets of the Company to another Person, then
the holder of this Note will thereafter be entitled to receive, upon the
conversion of this Note in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Company Stock
upon such reorganization, reclassification, consolidation, merger, sale or
conveyance, in respect of that number of shares of 































                                          11

Class A Common Stock into which this Note might have been converted immediately
prior to such reorganization, reclassification, consolidation, merger, sale or
conveyance; and, in any such case, appropriate adjustments (as determined in
good faith by the Board of Directors of the Company) shall be made to assure
that the provisions hereof (including provisions with respect to changes in, and
other adjustments of, the Conversion Price) shall thereafter be applicable, as
nearly as reasonably may be practicable, in relation to any securities or other
assets thereafter deliverable upon conversion of this Note.

               7.5  Certificate as to Adjustments.  Whenever the Conversion
                    -----------------------------
Price or the securities or other property deliverable upon the conversion of
this Note shall be adjusted pursuant to the provisions hereof, the Company shall
promptly give written notice thereof to the holder of this Note, in the manner
specified in Section 9 of this Note, stating the adjusted Conversion Price and
the securities or other property deliverable upon conversion of this Note calcu-
lated to the nearest cent or the nearest one-hundredth of a share and setting
forth in reasonable detail the method of calculation and the facts requiring
such adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

               7.6  Fractional Shares.  Notwithstanding any other provision of
                    -----------------
this Note, the Company shall not be required to issue fractions of shares upon
conversion of this Note or to distribute certificates which evidence fractional
shares.  In lieu of fractional shares, the Company may make payment to the
holder of this Note, at the time of conversion of this Note as herein provided,
of an amount in cash equal to such fraction multiplied by the Conversion Price.

               7.7  No Rights or Liability as a Stockholder.  This Note does not
                    ---------------------------------------
entitle the holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Company to convert this Note into shares of Class A Common Stock, and no
enumeration herein of the rights or privileges of the holder of this Note, shall
give rise to any liability to such holder as a stockholder of the Company.

          5.   Defaults and Remedies.  
               ---------------------

               (a)  Events of Default.  An "Event of Default" shall occur if:
                    -----------------

                    (i)  the Company shall default in the payment of the
principal of this Note, when and as the same shall become due and payable,
whether at maturity or at a date fixed for prepayment or by acceleration or
otherwise and such default shall continue for a period of ten days; or

same shall become due and payable and such default shall continue for a period
of 20 days; or

                 (iii)  an involuntary proceeding shall be commenced or an

proceeding or file any petition seeking relief 





























                                          3





<PAGE>







under Title 11 of the United States Code, as now constituted or hereafter
amended, or any other Federal or state bankruptcy, insolvency, receivership or
similar law, (b) consent to the institution of or the entry of an order for
relief against it, or fail to contest in a timely and appropriate manner, any
proceeding or the filing of any petition described in paragraph (iii) of this
Section 5(a), (c) apply for or consent to the appointment of a receiver,

clauses (a)(iii) or (iv) of this Section 5, then the outstanding principal of
and all accrued interest on this Note shall automatically become immediately due
and payable, without presentment, demand, protest or notice of any kind, all of
which are expressly waived.  If any other Event of Default occurs and is
continuing, the holders of at least a majority of the aggregate outstanding
principal amount of this Note and the other Notes issued pursuant to the Share
Redemption Agreement, by written notice to the Company, may declare the
principal of and accrued interest on the Notes issued pursuant to the Share
Redemption Agreement to be due and payable immediately.  Upon such declaration,
such principal and interest shall become immediately due and payable.  The
holders of a majority of the aggregate outstanding principal amount of this Note
and the other Notes issued pursuant to the Share Redemption Agreement may
rescind an acceleration and its consequences if all existing Events of Default
have been cured or waived, except nonpayment of principal or interest that has
become due solely because of the acceleration, and if the rescission would not
conflict with any judgment or decree.  Any notice or rescission shall be given
in the manner specified in Section 9 hereof.

          6.   Subordination.  This Note and the other Notes issued pursuant to
               -------------

stated maturity.

          "Senior Indebtedness" shall mean (i) the principal of and interest on
           -------------------
(including without limitation any interest that accrues after the commencement
of any case, proceeding or other legal action relating to the bankruptcy,
insolvency or reorganization of the Company whether or not such interest

monetary obligation of the Company arising out of or in connection with the
Senior Subordinated Notes or the Subordinated Note and Stock Purchase Agreement
and (iii) any indebtedness for borrowed money of the Company, whether

guaranteed by the Company, unless the instrument creating or evidencing the same

          "Subordinated Indebtedness" shall mean (i) the principal of and
           -------------------------
interest on this Note and the other Notes issued pursuant to the Share
Redemption Agreement; and (ii) any other monetary obligations of the Company
arising out of or in connection with the Share Redemption Agreement or such

                                          5





<PAGE>







shall have occurred shall have been paid in full or duly provided for in a
manner satisfactory to the holders of the Senior Indebtedness, as the case may
be, no direct or indirect payment (in cash, property, securities or by set-off
or otherwise) shall be made on account of the principal of or interest on this
Note or the other Notes issued pursuant to the Share Redemption Agreement or as
a sinking fund for such Notes or in respect of any redemption, retirement,
purchase or other acquisition of such Notes.

               (d)  Limitation on Remedies.  As long as any Senior Indebtedness
                    ----------------------
remains outstanding, the holder of this Note shall not declare or join in any
declaration of this Note to be due and payable by reason of any Event of Default
or otherwise take any action against the Company (including, without limitation,
commencing any legal action against the Company or filing or joining in the
filing of any insolvency petition against the Company).

               (e)  Subordination Upon Certain Events.  Upon the occurrence of
                    ---------------------------------
any Event of Default under Sections 5(a)(iii) or (iv) of this Note:

                    (i)  Upon any payment or distribution of assets of the
Company to creditors of the Company, holders of Senior Indebtedness shall be
entitled to receive payment in full in cash before the holders of Subordinated
Indebtedness shall be entitled to receive any payment in respect of the
Subordinated Indebtedness.

                   (ii)  Until all Senior Indebtedness is paid in full in cash,
any distribution to which the holders of Subordinated Indebtedness would be
entitled but for this Section 6 shall be made to holders of Senior Indebtedness,
as their interests may appear.

                  (iii)  For purposes of this Section 6, a distribution may
consist of cash, securities or other property, by set-off or otherwise.

               (f)  Payments and Distributions Received.  If the holders of the
                    -----------------------------------
Subordinated Indebtedness shall have received any payment from or distribution
of assets of the Company in respect of the Subordinated Indebtedness in
contravention of the terms of this Section 6 before all Senior Indebtedness is
paid in full in cash, then and in such event such payment or distribution shall
be received and held in trust for and shall be paid over or delivered to the
holders of Senior Indebtedness (or their authorized agent) to the extent
necessary to pay all such Senior Indebtedness in full in cash.

<PAGE>








               (g)  Subrogation.  After all amounts payable under or in respect
                    -----------
of Senior Indebtedness are paid in full in cash, the holders of the Subordinated
Indebtedness shall be subrogated to the rights of holders of Senior Indebtedness
to receive payments or distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Subordinated
Indebtedness have been applied to the payment of Senior Indebtedness.  A
distribution made under this Section 6 to a holder of Senior Indebtedness which
otherwise would have been made to the holders of the Subordinated Indebtedness
is not, as between the Company and the holders of the Subordinated Indebtedness,
a payment by the Company on Senior Indebtedness.

               (h)  Relative Rights.  This Section defines the relative rights
                    ---------------
of the holders of the Subordinated Indebtedness and the holders of Senior
Indebtedness.  Nothing in this Section shall:  (i) impair, as between the
Company and the holders of the Subordinated Indebtedness, the obligation of the
Company, which is absolute and unconditional, to pay principal of and interest
on Subordinated Indebtedness in accordance with its terms; or (ii) effect the
relative rights of holders of Subordinated Indebtedness and creditors of the
Company other than holders of Senior Indebtedness.

               (i)  Subordination May Not Be Impaired by the Company.  No right
                    ------------------------------------------------
of any holder of any Senior Indebtedness to enforce the subordination of the
Subordinated Indebtedness shall be impaired by any failure by the Company to
comply with this Note.  

               (j)  Payments.  A payment with respect to principal of or
                    --------
interest on the Subordinated Indebtedness shall include, without limitation,
payment of principal of, and interest on the Subordinated Indebtedness, any
depositing of funds for the defeasance of the Subordinated Indebtedness and any
payment on account of mandatory prepayment or optional prepayment provisions.  

               (k)  Subordination Not Impaired; Benefit of Subordination.  The
                    ----------------------------------------------------
holder of this Note agrees and consents that without notice to or assent by such
holder, and without affecting the liabilities and obligations of the Company and
such holder and the rights and benefits of the holders of the Senior
Indebtedness set forth herein:

                      (i)  the obligations and liabilities of the Company and
any other party or parties for or upon the Senior Indebtedness may, from time to
time, be increased, renewed, refinanced, extended, modified, amended, 































                                          7





<PAGE>







restated, compromised, supplemented, terminated, waived or released;

                     (ii)  the holders of Senior Indebtedness, and any
representative or representatives acting on behalf thereof, may exercise or
refrain from exercising any right, remedy or power granted by or in connection
with any agreements relating to the Senior Indebtedness; and

                    (iii)  any balance or balances of funds with any holder of
Senior Indebtedness at any time outstanding to the credit of the Company may,
from time to time, in whole or in part, be surrendered or released;

all as the holders of the Senior Indebtedness, and any representative or
representatives acting on behalf thereof, may deem advisable, and all without
impairing, abridging, diminishing, releasing or affecting the subordination of
the Subordinated Indebtedness to the Senior Indebtedness provided for herein.

               (l)  Modification of Subordination Provisions.  The subordination
                    ----------------------------------------
provisions of this Note are for the benefit of the holders from time to time of
Senior Indebtedness and, so long as any Senior Indebtedness remains unpaid,
these provisions may not be modified, rescinded or canceled in whole or in part
without the prior written consent thereto of the holders of a majority of the
aggregate principal amount outstanding of Senior Subordinated Notes and the
holders of a majority of the aggregate principal amount outstanding of any other
Senior Indebtedness which the Company may from time to time designate as
entitled to the benefits of this Section 5(l).

               (m)  Miscellaneous.
                    -------------

                      (i)  To the extent permitted by applicable law, the holder
of this Note and the Company hereby waive (1) notice of acceptance hereof by the
holders of the Senior Indebtedness and (2) all diligence in the collection or
protection of or realization upon the Senior Indebtedness.

                     (ii)  The Company and the holder of this Note hereby
expressly agree that the holders of Senior Indebtedness may enforce any and all
rights derived herein by suit, either in equity or law, for specific performance
of any agreement contained in these subordination provisions or for judgment at
law and any other relief whatsoever appropriate to such action or procedure.

<PAGE>








                    (iii)  The holder of this Note acknowledges and agrees that
the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of Senior Indebtedness, whether
such Senior Indebtedness was created or acquired before or after the issuance of
this Note, and each holder of Senior Indebtedness shall be deemed conclusively
to have relied upon such subordination provisions in acquiring and continuing to
hold the Senior Indebtedness held by such holder, as the case may be.

          7.   Conversion.
               ----------

               7.1  Company Right to Require Conversion.
                    -----------------------------------

                    (a)  Conversion.  At any time or from time to time after the
                         ----------
occurrence of a Trigger Event and upon notice given to the holder of this Note
as provided below, the Company may, subject to the terms and conditions of this
Section 7, convert this Note, in whole or in part, into fully paid and
nonassessable shares of Class A Common Stock at the Conversion Price.  The
number of shares of Class A Common Stock to be issued upon conversion of this
Note shall be equal to the quotient of (x) the principal amount of this Note
then being converted and (y) the Conversion Price.  The Company may convert this
Note (or a portion of the outstanding principal amount of this Note) by giving
written notice (a "Conversion Notice") of such mandatory conversion to the
                   -----------------
holder of this Note, at least five Business Days prior to the date fixed for
such conversion.  Such notice shall be given in the manner specified in Section
9 of this Note.

                    (b)  Payment of Interest.  When all or any portion of this
                         -------------------
Note is converted, all interest accrued and unpaid (whether or not currently
payable) to the date of such conversion on the portion of this Note converted
shall be immediately due and payable in cash, which payment shall accompany the
shares of Class A Common Stock issued upon such conversion.

                    (c)  Delivery of Shares and New Notes.  As soon as
                         --------------------------------
practicable after conversion of this Note (or a portion of the outstanding
principal amount of this Note) pursuant to Section 7.1(a), the Company shall
promptly (x) issue and deliver to the holder of this Note a certificate or
certificates for the number of shares of Class A Common Stock set forth in the
Conversion Notice, in such name or names as may be designated by such holder,
along with a check for the amount of cash to be paid in accordance with
Section 7.1(b) in respect of accrued and unpaid interest, if any, on the portion
of this Note then being 






























                                          9





<PAGE>







converted, against delivery to the Company of this Note accompanied by proper
instruments of transfer and (y) cancel this Note upon surrender hereof and, if
this Note is being converted in part only, execute and deliver a new Note in
replacement of the Note surrendered.  The new Note issued by the Company
pursuant to clause (y) of the preceding sentence shall be the same as the Note
submitted for conversion except that (1) it will be dated the date that the Note
submitted for conversion is cancelled and (2) it will be issued in the principal
amount of the unconverted portion of the Note submitted for conversion.

                    (d)  When Conversion Effective.  The conversion of this Note
                         -------------------------
shall be deemed to have been effective on the date fixed by the Company for such
conversion in the Conversion Notice (the "Conversion Date"), whether or not this
                                          ---------------
Note is actually surrendered for conversion, and the Person in whose name any
certificate for shares of Class A Common Stock shall be issuable upon such
conversion, as provided in Section 7.1(c), shall be deemed to be the record
holder of such shares of Class A Common Stock for all purposes on the Conversion
Date.  On and after the Conversion Date, all rights of the holder of this Note
with respect to the portion of this Note converted into shares of Class A Common
Stock, shall cease and terminate, except the right to receive a certificate for
shares of Class A Common Stock with respect to the portion of this Note so
converted and the right to receive cash in accordance with Section 7.1(b) in
respect of accrued and unpaid interest, if any, on the portion of this Note so
converted; and the portion of this Note so converted shall no longer be deemed
to be outstanding, whether or not this Note has been surrendered to the Company
for conversion.

               7.2  Adjustment of Conversion Price.  If the Company shall, at
                    ------------------------------
any time or from time to time, (a) declare a dividend on the Company Stock
payable in shares of its capital stock (including Company Stock), (ii) subdivide
the outstanding Company Stock, (iii) combine the outstanding Company Stock into
a smaller number of shares, or (iv) issue any shares of its capital stock in a
reclassification of the Company Stock (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
corporation), then in each such case, the Conversion Price in effect at the time
of the record date for such dividend or of the effective date of such
subdivision, 




































                                          10





<PAGE>







combination or reclassification shall be adjusted to that price which will
permit the number of shares of Class A Common Stock into which this Note may be
converted to be increased or reduced in the same proportion as the number of
shares of Company Stock are increased or reduced in connection with such
dividend, subdivision, combination or reclassification.  Any such adjustment
shall become effective immediately after the record date of such dividend or the
effective date of such subdivision, combination or reclassification.  Such
adjustment shall be made successively whenever any event listed above shall
occur.  If a dividend is declared and such dividend is not paid, the Conversion
Price shall again be adjusted to be the Conversion Price in effect immediately
prior to such record date.

               7.3  De Minimis Adjustments.  No adjustment in the Conversion
                    ----------------------
Price shall be made if the amount of such adjustment would result in a change in
the Conversion Price per share of less than $.02, but in such case any adjust-
ment that would otherwise be required to be made shall be carried forward and
shall be made at the time of and together with the next subsequent adjustment,
which together with any adjustment so carried forward, would result in a change
in the Conversion Price of $.05 per share.  If the Company shall, at any time or
from time to time, issue Company Stock by way of dividends on any stock of the

Person (other than a merger or consolidation of the Company in which the Company
is the continuing corporation and which does not result in any reclassification

the holder of this Note will thereafter be entitled to receive, upon the
conversion of this Note in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Company Stock
upon such reorganization, reclassification, consolidation, merger, sale or
conveyance, in respect of that number of shares of

prior to such reorganization, reclassification, consolidation, merger, sale or
conveyance; and, in any such case, appropriate adjustments (as determined in
good faith by the Board of Directors of the Company) shall be made to assure
that the provisions hereof (including provisions with respect to changes in, and
other adjustments of, the Conversion Price) shall thereafter be applicable, as
nearly as reasonably may be practicable, in relation to any securities or other
assets thereafter deliverable upon conversion of this Note.

               7.5  Certificate as to Adjustments.  Whenever the Conversion
                    -----------------------------

this Note shall be adjusted pursuant to the provisions hereof, the Company shall
promptly give written notice thereof to the holder of this Note, in the manner
specified in Section 9 of this Note, stating the adjusted Conversion Price and
the securities or other property deliverable upon conversion of this Note calcu-
lated to the nearest cent or the nearest one-hundredth of a share and setting
forth in reasonable detail the method of calculation and the facts requiring
such adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

               7.6  Fractional Shares.  Notwithstanding any other provision of
                    -----------------
this Note, the Company shall not be required to issue fractions of shares upon
conversion of this Note or to distribute certificates which evidence fractional
shares.  In lieu of fractional shares, the Company may make payment to the
holder of this Note, at the time of conversion of this Note as herein provided,
of an amount in cash equal to such fraction multiplied by the Conversion Price.

               7.7  No Rights or Liability as a Stockholder.  This Note does not
                    ---------------------------------------
entitle the holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Company to convert this Note into shares of Class A Common Stock, and no
enumeration herein of the rights or privileges of the holder of this Note, shall
give rise to any liability to such holder as a stockholder of the Company.

          2.   Securities Subject to this Agreement.
               ------------------------------------

               (a)  Registrable Securities.  For the purposes of this Agreement,
                    ----------------------
Registrable Securities will cease to be Registrable Securities when (i) a
registration statement covering such Registrable Securities has been declared
effective under the Act by the SEC and such Registrable Securities have been
disposed of pursuant to such effective registration statement or (ii) the entire
amount of Registrable Securities proposed to be sold in a single sale are or, in
the opinion of counsel satisfactory to the Company and the Holder, each in their

basis of the instructions, notice or election received from the registered owner

          3.   Demand Registration.
               -------------------

               (a)  Request for Demand Registration.  At any time after 18
                    -------------------------------
months from the date of the execution of this Agreement, the Designated Holders
holding at least 25% of the Registrable Securities held by all of the Designated
Holders (the "Initiating Holders") may request the registration of Registrable
              ------------------
Securities under the Act, and under the securities or blue sky laws of any
jurisdiction designated by such holder or holders (each such registration under
this Section 3(a) that satisfies the requirements set forth in Section 3(b) is
referred to herein as a "Demand Registration").  Notwithstanding the foregoing,
                         -------------------
(i) the Company will not be required to effect a Demand Registration within the
period beginning on the effective date of a registration statement filed by the
Company on its behalf and ending on the expiration of any lock-up period
reasonably required by the underwriters, if any, in connection therewith,
(ii) in no event shall the Company be required to effect more than four Demand
Registrations and (iii) in no event shall the Company be required to effect a
registration pursuant to this Section 3 within the six-month period occurring
immediately subsequent to the effectiveness (within the meaning of Section 3(b))
of a registration statement filed pursuant to this Section 3(a).  For purposes
of clause (ii) of the preceding

                                                                        5


sentence, two or more registrations filed in response to one demand shall be
counted as one registration statement.  Each such request for a Demand
Registration by the Initiating Holders in respect thereof shall specify the
amount of the Registrable Securities proposed to be sold, the intended method of
disposition thereof and the jurisdictions in which registration is desired. 
Upon a request for a Demand Registration, the Company shall promptly take such
steps as are necessary or appropriate to prepare for the registration of the
Registrable Securities to be registered.  Within fifteen (15) days after the
receipt of such request, the Company shall give written notice thereof to all
other Designated Holders and include in such registration all Registrable
Securities held by a Designated Holder from whom the Company has received a
written request for inclusion therein within twenty (20) days after delivery of
the foregoing notice, which date shall be no later than ten (10) days prior to
the filing of the registration statement.  Each such request will also specify
the number of Registrable Securities to be registered, the intended method of
disposition thereof and the jurisdictions in which registration is desired. 
Unless the Initiating Holders holding the majority of the Registerable
Securities held by all Initiating Holders to be included in a requested Demand
Registration consent in writing, (i) no other party, including the Company (but
not including any other Designated Holder), shall be permitted to offer
securities under any such Demand Registration.  

               (b)  Effective Demand Registration.  The Company shall use its
                    -----------------------------
best efforts to cause any such Demand Registration to become effective not later
than ninety (90) days after it receives a request under Section 3(a); provided,
                                                                      --------
however, that with respect to a Demand Registration that is an Initial Public
- -------
Offering, the Company shall use its best efforts to cause such Demand
Registration to become effective not less than 150 days after it receives a
request under Section 3(a).

               (c)  Expenses.  In any registration initiated as a Demand
                    --------
Registration, the Company shall pay all Registration Expenses in connection
therewith, whether or not such requested Demand Registration becomes effective,
except that after the first three Demand Registrations become effective in
accordance with Section 3(b), the Company will no longer be obligated to pay the
Registration Expenses for any additional registrations initiated as Demand
Registrations. 

               (d)  Underwriting Procedures.  If the Initiating Holders holding
                    -----------------------
a majority of the Registrable Securities held by all Initiating Holders to which
the requested Demand Registration relates so elect, the offering of such
Registrable Securities pursuant to such requested Demand Registration shall be
in the form of a firm commitment underwritten offering and the managing
underwriter or underwriters selected for such offering shall be the Approved
Underwriter selected in accordance with Section 3(e).  In such event, if the
Approved Underwriter advises the Company in writing that, in its opinion, the
aggregate amount 































<PAGE>




                                                                        6


of such Registrable Securities requested to be included in such offering is
sufficiently large to have a material adverse effect on the success of such
offering, then the Company shall include in such registration only the aggregate
amount of Registrable Securities that in the opinion of the Approved Underwriter
may be sold without any such effect on the success of such offering (the
"Approved Underwriter Amount"), and each Designated Holder shall be entitled to
 ---------------------------
have included in such registration Registrable Securities equal to its pro rata
portion of the Approved Underwriter Amount, as based on the amounts of
Registrable Securities owned by each such Designated Holder.  

               (e)  Selection of Underwriters.  If any requested Demand
                    -------------------------
Registration is in the form of an underwritten offering, the Initiating Holders
holding a majority of the Registrable Securities held by all Initiating Holders
to be included in the requested Demand Registration shall select and obtain an
investment banking firm of national reputation to act as the managing
underwriter of the offering (the "Approved Underwriter").  Notwithstanding the
                                  --------------------
foregoing, however, in any Demand Registration that is an Initial Public
Offering, the Approved Underwriter so selected shall be subject to the approval
of the Company, such approval not to be unreasonably withheld.

          4.   Piggy-Back Registration.  
               -----------------------

               (a)  Piggy-Back Rights.  If the Company proposes to file a
                    -----------------
registration statement under the Act with respect to an offering by the Company
for its own account of any class of security (other than a registration
statement on Form S-4 or S-8 (or any successor form thereto) under the Act, then
the Company shall give written notice of such proposed filing to each of the
Holders at least thirty (30) days before the anticipated filing date, and such
notice shall describe in detail the proposed registration and distribution
(including those jurisdictions where registration under the securities or blue
sky laws is intended) and offer such Holders the opportunity to register the
number of Registrable Securities as each such Holder may request within seven
(7) days after delivery of the foregoing notice.  The Company shall use its best
efforts (within ten (10) days of the notice provided for in the preceding
sentence) to cause the managing underwriter or underwriters of an underwritten
offering proposed by the Company (the "Company Underwriter") to permit the
                                       -------------------
Holders who have requested to participate in the registration for such offering
to include such Registrable Securities in such offering on the same terms and
conditions as the securities of the Company included therein.  Notwithstanding
the foregoing, if the Company Underwriter delivers a written opinion to the
Holders of Registrable Securities that the total amount of securities which they
and the Company intend to include in such offering (the "Total Securities") is

of the Total Securities, then the securities proposed to be included in such
registration by all Holders (other than Designated Holders) shall be reduced pro
rata based on the amounts of Registrable

Securities owned by such Holders to the extent necessary to reduce the Total
Securities to the amount recommended by the Company Underwriter, and if the
amount of Total Securities is still sufficiently large so as to prevent the
Company from effecting a successful offering of the Total Securities, then the
securities to be included for the account of the Designated Holders shall be
reduced pro rata based on the amounts of Registrable Securities owned by such
Designated Holders to the extent necessary to reduce the Total Securities to the
amount recommended by the Company Underwriter.

               (b)  Priority of Registrations.  If the Company proposes to
                    -------------------------
register securities pursuant to Section 4(a) hereof on the same day that the
Designated Holders request a registration pursuant to Section 3(a) hereof, then
the Demand Registration requested pursuant to Section 3(a) hereof shall be given
priority.

               (c)  Expenses.  The Company shall bear all Registration Expenses
                    --------
in connection with any registration pursuant to this Section 4.

          5.   Holdback Agreements. 
               -------------------

               (a)  Restrictions on Public Sale by Holders.  To the extent not
                    --------------------------------------
inconsistent with applicable law, (i) each Holder agrees not to effect any
public sale or distribution of any Registrable Securities being registered or of
any securities convertible into or exchangeable or exercisable for such
Registrable Securities, including a sale pursuant to Rule 144 under the Act,
during the seven (7) days prior to, and during the 180-day period beginning on,
the effective date of such Demand Registration or Piggy-Back Registration or
other underwritten offering (except as part of such registration), if and to the
extent requested by any other Holder, in the case of a non-underwritten public
offering, or if and to the extent requested by the Company Underwriter, in the
case of an underwritten public offering and (ii) unless the prior written
consent of Whitney and CVCA is obtained, Mintz, Adams and Rubinstein agree not
to effect any public sale or distribution, other than pursuant to a registration
statement filed under the Act, of any Registrable Securities of any securities
convertible into or exchangeable or exercisable for such Registrable Securities
during the two years following the effective date of an Initial Public Offering,
including a sale pursuant to Rule 144 under the Act.

               (b)  Restrictions on Public Sale by the Company.  The Company
                    ------------------------------------------
agrees not to effect any public sale or distribution of any of its securities
for its own account (except pursuant to registrations on Form S-4 or S-8 (or any
successor form thereto) under the Act) during the ninety (90) day period
beginning on the later of (i) the effective date of any registration statement
in which the Holders are participating and (ii) the commencement of a public
distribution of Registrable Securities pursuant to such registration statement.

          6.   Registration Procedures.  
               -----------------------

               (a)  Obligations of the Company.  Whenever registration of
                    --------------------------
Registrable Securities has been requested pursuant to Section 3 or 4 of this
Agreement, the Company shall use its best efforts to effect the registration and
sale of such Registrable Securities in accordance with the intended method of

request, the Company shall, as expeditiously as possible:

                    (i)     prepare and file with the SEC (in any event not
later than sixty (60) Business Days after receipt of a request to file a
registration statement with respect to Registrable Securities) a registration
statement on any form for which the Company then qualifies, which counsel for
the Company and Holders' Counsel shall deem appropriate and which shall be
available for the sale of such Registrable Securities in accordance with the
intended method of distribution thereof, and use its best efforts to cause such
registration statement to become effective; provided, however, that before
                                            --------  -------
filing a registration statement or prospectus or any amendments or supplements
thereto, the Company shall (A) provide Holders' Counsel and any other Inspector

of such registration statement and each prospectus included therein (and each
amendment or supplement thereto) to be filed with the SEC, which documents shall
be subject to the review of Holders' Counsel, and (B) notify Holders' Counsel
and each seller of Registrable Securities pursuant to such registration
statement of any stop order issued or threatened by the SEC and take all
reasonable action required to prevent the entry of such stop order or to remove
it if entered;

                    (ii)    prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for

sold, but not before the expiration of the applicable period referred to in
Section 4(3) of the Act and Rule 174 thereunder, if applicable), and comply with
the provisions of the Act with respect to the disposition of all Registrable

accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement; 

                    (iii)   as soon as reasonably possible, furnish to each
seller of Registrable Securities, prior to filing a registration statement,

thereafter such number of copies of such registration statement, each amendment
and supplement thereto (in each case including all exhibits thereto),

                                                                        9


the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as each such seller may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such seller;

                    (iv)    use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions as any seller of Registrable Securities may reasonably request,
and to continue such qualification in effect in each such jurisdiction for as
long as is permissible pursuant to the laws of such jurisdiction, or for as long
as any such seller reasonably requests or until all of such Registrable
Securities are sold, whichever is shortest, and do any and all other acts and
things which may be reasonably necessary or advisable to enable any such seller
to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller; provided, however, that the Company shall not
                                 --------  -------
be required to (A) qualify generally to do business in any jurisdiction where it
would not otherwise be required to qualify but for this Section 6(a)(iv),
(B) subject itself to taxation in any such jurisdiction or (C) consent to
general service of process in any such jurisdiction;

                    (v)     use its best efforts to obtain all other approvals,

                    (vi)    notify each seller of Registrable Securities at any
time when a prospectus relating thereto is required to be delivered under the
Act, upon discovery that, or upon the happening of any event as a result of
which, the prospectus included in such registration statement contains an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they were made, and the Company shall
promptly prepare a supplement or amendment to such prospectus and furnish to
each such seller a reasonable number of copies of a supplement to or amendment
of such prospectus as may be necessary so that, after delivery to the purchasers
of such Registrable Securities, such prospectus shall not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they were made;

                    (vii)   enter into and perform customary agreements
(including an underwriting agreement in customary form with the Approved
Underwriter or Company Underwriter, if any, selected as provided in Section 3 or
4) and take such other actions as are reasonably required in order to expedite
or facilitate the disposition of such Registrable Securities;

                    (viii)  make available for inspection by any seller of
Registrable Securities, any managing underwriter participating in any
disposition pursuant to such registration statement, Holders' Counsel and any
attorney, accountant or other agent retained by any such seller or any managing
underwriter (each, an "Inspector" and, collectively, the "Inspectors"), all
                       ---------                          ----------
financial and other records, pertinent corporate documents and properties of the
Company and any subsidiaries thereof as may be in existence at such time
(collectively, the "Records") as shall be reasonably necessary to enable them to
                    -------
exercise their due diligence responsibility, and cause the Company's and any
subsidiaries' officers, directors and employees, and the independent public
accountants of the Company, to supply all information reasonably requested by
any such Inspector in connection with such registration statement.

                    (ix)    if such sale is pursuant to an underwritten
offering, obtain a "cold comfort" letter from the Company's independent public
accountants in customary form and covering such matters of the type customarily
covered by "cold comfort" letters, as Holders' Counsel or the managing
underwriter reasonably request; 

                    (x)     furnish, at the request of any seller of Registrable
Securities on the date such securities are delivered to the underwriters for
sale pursuant to such registration or, if such securities are not being sold
through underwriters, on the date the registration statement with respect to
such securities becomes effective, an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and to the seller making such request, covering such legal
matters with respect to the registration in respect of which such opinion is
being given as such seller may reasonably request and as are customarily
included in such opinions;

                    (xi)    otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable but no later than fifteen (15) months
after the effective date of the registration statement, an earnings statement
covering a period of twelve (12) months beginning after the effective date of
the registration statement, in a manner which satisfies the provisions of
Section 11(a) of the Act;

                    (xii)   cause all such Registrable Securities to be listed
on each securities exchange on which similar securities issued by the Company
are then listed or on which the Initiating Holders reasonably request that such
Registrable Securities be listed, subject to the satisfaction of the applicable
listing requirements of each such exchange;

                    (xiii)  keep each seller of Registrable Securities advised
in writing as to the initiation and progress of any registration under Section 3
or 4 hereunder; 






























<PAGE>




                                                                       11



                    (xiv)   provide officers' certificates and other customary
closing documents;

                    (xv)    cooperate with each seller of Registrable Securities
and each underwriter participating in the disposition of such Registrable
Securities and their respective counsel in connection with any filings required
to be made with the National Association of Securities Dealers, Inc. (the
"NASD"); and 
 ----

                    (xvi)   use its best efforts to take all other steps
necessary to effect the registration of the Registrable Securities contemplated
hereby.  

               (b)  Seller Information.  The Company may require each seller of
                    ------------------
Registrable Securities as to which any registration is being effected to furnish
to the Company such information regarding such Seller and the distribution of
such securities as the Company may from time to time reasonably request in
writing, and in the case of an underwritten offering, such Seller shall agree to
sell its Registrable Securities to the Underwriters in such offering.

               (c)  Notice to Discontinue.  Each Holder agrees that, upon
                    ---------------------
receipt of any notice from the Company of the happening of any event of the kind
described in Section 6(a)(vi), such Holder shall forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such Holder's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 6(a)(vi) and,
if so directed by the Company, such Holder shall deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities
which is current at the time of receipt of such notice.  If the Company shall
give any such notice, the Company shall extend the period during which such
registration statement shall be maintained effective pursuant to this Agreement
(including, without limitation, the period referred to in Section 6(a)(ii)) by
the number of days during the period from and including the date of the giving
of such notice pursuant to Section 6(a)(vi) to and including the date when the
Holder shall have received the copies of the supplemented or amended prospectus
contemplated by and meeting the requirements of Section 6(a)(vi). 

               (d)  Sale to Underwriter.  Subject to the limitations on
                    -------------------
inclusion of Registrable Securities in a registration under Sections 3(d) and
4(a), in lieu of converting any shares of Series A Preferred Stock or Class B
Common Stock into Registrable Securities to be included in a registration under
Section 3 or 4 prior to or simultaneously with the filing or the effectiveness
of any registration statement filed pursuant thereto, the holder of such
Series A Preferred Stock or Class B Common Stock may sell such Series A
Preferred Stock or Class B Common Stock to the Approved Underwriter or the
Company Underwriter, as the case may

                                                                       12


be, and any other underwriters of the offering being registered (collectively,
the Approved Underwriter or Company Underwriter, as the case may be, and such
other underwriters, the "Underwriters") if the Underwriters consent thereto and
                         ------------
if the Underwriters undertake to convert such shares of Series A Preferred Stock
or Class B Common Stock into Registrable Securities before making any
distribution pursuant to such registration statement and to include such
Registrable Securities among the Registrable Securities being offered pursuant
to such registration statement.  Assuming timely delivery by the Holder of the
Series A Preferred Stock certificates or Class B Common Stock certificates to or
for the account of the Underwriters, the Company agrees to cause the relevant
Registrable Securities to be issued so as to permit the Underwriters to make and
complete the distribution (including the distribution of such Registrable
Securities) contemplated by the underwriting.

          7.   Registration Expenses.  The Company shall pay all expenses (other
               ---------------------
than (i) underwriting discounts and commissions and (ii) the fees, charges and
expenses of any Inspector) arising from or incident to the performance of, or
compliance with, this Agreement, including, without limitation, (a) SEC, stock
exchange and NASD registration and filing fees, (b) all fees and expenses
incurred in complying with securities or blue sky laws (including, without
limitation, reasonable fees, charges and disbursements of counsel in connection
with blue sky qualifications of the Registrable Securities), (c) all printing,
messenger and delivery expenses and (d) the fees, charges and disbursements of
counsel to the Company and of its independent public accountants and any other
accounting and legal fees, charges and expenses incurred by the Company (includ-
ing, without limitation, any expenses arising from any special audits incident
to or required by any registration or qualification) in connection with any
requested Demand Registration or piggy-back registration pursuant to the terms
of this Agreement, regardless of whether the registration statement filed in
connection with such registration is declared effective.  In connection with
each registration hereunder, the Company shall reimburse the Holders of Regis-
trable Securities being registered in such registration for the reasonable fees,
charges and disbursements of not more than one Holders' Counsel.  All of the
expenses described in this Section 7 are referred to in this Agreement as
"Registration Expenses."  Notwithstanding the foregoing provisions of this
 ---------------------
Section 7, the Company's obligation to pay Registration Expenses shall be
limited as provided in Section 3(c). 

          8.   Indemnification; Contribution.
               -----------------------------

               (a)  Indemnification by the Company.  The Company agrees to
                    ------------------------------
indemnify and hold harmless each Holder, its directors, officers, partners,
employees, advisors and agents, and each Person who controls (within the meaning
of the Act or the Exchange Act) such Holder, to the extent permitted by law,
from and against any and all losses, claims, damages, expenses (including,
without limitation, reasonable costs of investigation

                                                                       13


and fees, disbursements and other charges of counsel) or other liabilities
resulting from or arising out of or based upon any untrue, or alleged untrue,
statement of a material fact contained in any registration statement, prospectus
or preliminary prospectus or notification or offering circular (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, except insofar as the same are caused by
or contained in any information furnished in writing to the Company by such
Holder expressly for use therein.  The Company shall also indemnify any
underwriters of the Registrable Securities, their officers, directors and
employees, and each Person who controls any such underwriter (within the meaning
of the Act and the Exchange Act) to the same extent as provided above with
respect to the indemnification of the Holders of Registrable Securities.

               (b)  Indemnification by Holders.  In connection with any
                    --------------------------
registration in which a Holder is participating pursuant to Section 3 or 4
hereof, each such Holder shall furnish to the Company in writing such informa-
tion with respect to such Holder as the Company may reasonably request or as may
be required by law for use in connection with any registration statement or
prospectus to be used in connection with such registration and each Holder
agrees to indemnify and hold harmless the Company, any underwriter retained by
the Company and their respective directors, officers, employees and each Person
who controls (within the meaning of the Act and the Exchange Act) the Company or
such underwriter to the same extent as the foregoing indemnity from the Company
to the Holders (subject to the proviso to this sentence and applicable law), but
only with respect to any such information furnished in writing by such Holder
expressly for use therein; provided, however, that the liability of any Holder
                           --------  -------
under this Section 8(b) shall be limited to the amount of the net proceeds
received by such Holder in the offering giving rise to such liability.

               (c)  Conduct of Indemnification Proceedings.  Any Person entitled
                    --------------------------------------
to indemnification hereunder (the "Indemnified Party") agrees to give prompt
                                   -----------------
written notice to the indemnifying party (the "Indemnifying Party") after the
                                               ------------------
receipt by the Indemnified Party of any written notice of the commencement of
any action, suit, proceeding or investigation or threat thereof made in writing
for which the Indemnified Party intends to claim indemnification or contribution
pursuant to this Agreement; provided, that, the failure so to notify the
                            --------  ----
Indemnifying Party shall not relieve the Indemnifying Party of any liability
that it may have to the Indemnified Party hereunder.  If notice of commencement
of any such action is given to the Indemnifying Party as above provided, the
Indemnifying Party shall be entitled to participate in and, to the extent it may
wish, jointly with any other Indemnifying Party similarly notified, to assume
the defense of such action at its own expense, with counsel chosen by 


































<PAGE>




                                                                       14


it and satisfactory to such Indemnified Party.  The Indemnified Party shall have
the right to employ separate counsel in any such action and participate in the
defense thereof, but the fees and expenses of such counsel (other than
reasonable costs of investigation) shall be paid by the Indemnified Party unless
(i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party
fails to assume the defense of such action with counsel satisfactory to the
Indemnified Party in its reasonable judgment, (iii) the named parties to any
such action (including any impleaded parties) have been advised by such counsel
that either (A) representation of such Indemnified Party and the Indemnifying
Party by the same counsel would be inappropriate under applicable standards of
professional conduct or (B) there may be one or more legal defenses available to
it which are different from or additional to those available to the Indemnifying
Party.  In either of such cases the Indemnifying Party shall not have the right
to assume the defense of such action on behalf of such Indemnified Party.  No
Indemnifying Party shall be liable for any settlement entered into without its
written consent, which consent shall not be unreasonably withheld.  The rights
accorded to any Indemnified Party hereunder shall be in addition to any rights
that such Indemnified Party may have at common law, by separate agreement or
otherwise.

               (d)  Contribution.  If the indemnification provided for in
                    ------------
Section 8(a) from the Indemnifying Party is unavailable to an Indemnified Party
in respect of any losses, claims, damages, expenses or other liabilities
referred to therein, then the Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages, expenses or other
liabilities in such proportion as is appropriate to reflect the relative fault
of the Indemnifying Party and Indemnified Party in connection with the actions
which resulted in such losses, claims, damages, expenses or other liabilities,
as well as any other relevant equitable considerations.  The relative faults of
such Indemnifying Party and Indemnified Party shall be determined by reference
to, among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact, was made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the Indemnifying Party's and
Indemnified Party's relative intent, knowledge, access to information and
opportunity to correct or prevent such action.  The amount paid or payable by a
party as a result of the losses, claims, damages, expenses or other liabilities
referred to above shall be deemed to include, subject to the limitations set
forth in Sections 8(a), 8(b) and 8(c), any legal or other fees, charges or
expenses reasonably incurred by such party in connection with any investigation
or proceeding.  

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by pro rata
allocation or by any other method of

                                                                       15


allocation which does not take account of the equitable considerations referred
to in the immediately preceding paragraph.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution pursuant to this Section 8(d).

          9.   Rule 144; Other Exemptions.  The Company covenants that it shall
               --------------------------
file any reports required to be filed by it under the Exchange Act and the rules
and regulations adopted by the SEC thereunder, and that it shall take such
further action as each Holder may reasonably request (including, but not limited
to, providing any information necessary to comply with Rules 144 and 144A under
the Act), all to the extent required from time to time to enable such Holder to
sell Registrable Securities without registration under the Act within the
limitation of the exemptions provided by (a) Rule 144 or Rule 144A under the
Act, as such rules may be amended from time to time, or (b) any other rules or
regulations now existing or hereafter adopted by the SEC.  The Company shall,
upon the request of any Holder, deliver to such Holder a written statement as to
whether the Company has complied with such requirements.

          10.  Miscellaneous.
               -------------

               (a)  Recapitalizations, Exchanges, etc.  The provisions of this
                    ---------------------------------
Agreement shall apply, to the full extent set forth herein with respect to the
Shares, to any and all shares of capital stock of the Company or any successor
or assign of the Company (whether by merger, consolidation, sale of assets or
otherwise) which may be issued in respect of, in exchange for or in substitution
of, the Shares and shall be appropriately adjusted for any stock dividends,
splits, reverse splits, combinations, recapitalizations and the like occurring

securities of the Company rights with respect to the registration of such

herein, the Company shall provide (by way of amendment to this Agreement or
otherwise) such more favorable terms or conditions to the Designated Holders
under this Agreement.

their rights under this Agreement.  The Company agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by it of the provisions of this Agreement and hereby agrees to waive in any
action for specific performance the defense that a remedy at law would be
adequate.

                              (d)  the Third Party Offeror shall have furnished
     evidence satisfactory to the Company in its reasonable judgment as to the
     financial ability of such Third Party Offeror to consummate the proposed

                              (a)  the Rightholders shall have the right to
     purchase all (but not less than all) of the Offered Securities at a
     purchase price equal to the Offer Price and upon the terms and conditions
     of the Third Party Offer.  Each Rightholder shall have the right to pur-
     chase that percentage of the Offered Securities determined by dividing (i)
     the total number of Shares then owned by such Rightholder by (ii) the total
     number of Shares then owned by all Rightholders participating in the
     purchase of the Offered Securities (including such Rightholder's Shares). 
     If any Rightholder does not fully subscribe for the number or amount of
     Offered Securities it is entitled to purchase, then each other
     participating Rightholder shall have the right to purchase that percentage
     of the Offered Securities not so subscribed for (the "Excess Offered

                              (b)  if the Rightholders do not elect to purchase
     all of the Offered Securities pursuant to clause (a) of this Section 3.1.3,
     the Investors (excluding any Investor that is a Selling Stockholder) shall
     have the right to sell, to the Third Party Offeror upon the terms set forth
     in the Third Party Offer, that number of Shares held by such Investor equal
     to that percentage of the Offered Securities determined by dividing (i) the
     total number of Shares then owned by such Investor by (ii) the total number
     of Shares owned by all Stockholders participating in the sale to the Third
     Party Offeror (including such Investor's Shares).  Shares to be sold to the
     Third Party Offeror by an Investor pursuant to this Section 3.1.3(b) shall
     be of the same class and series as the Offered Securities.  To the extent
     any Investor exercises its right to sell Shares pursuant to this
     Section 3.1.3(b), the number of shares of the Offered Securities to be sold
     to the Third Party Offeror by the Selling Stockholder shall be reduced; or

                              (c)  if any Rightholder or Rightholders (the
     "Purchasing Rightholders") elect to purchase all of the Offered Securities
      -----------------------
     pursuant to clause (a) of this Section 3.1.3, then, prior to the expiration
     of the Option Period, each other Rightholder who has declined to be a
     Purchasing Rightholder shall have the right to sell to the Purchasing
     Rightholders, upon the terms and conditions of the Third Party Offer, that
     number of Shares held by such Rightholder equal to that percentage of the
     Offered Securities determined by dividing (i) the total number of Shares
     then owned by such Rightholder by (ii) the total number of Shares then
     owned by all of the Stockholders requesting participation in the sale other
     than the Purchasing Rightholders.  Shares to be sold to the Purchasing
     Rightholders by a Rightholder pursuant to this Section 3.1.3(c) shall be of
     the same class and series as the Offered Securities.  To the extent any
     Rightholder exercises its rights to sell Shares pursuant to this Section
     3.1.3(c), the number of shares of the Offered Securities to be sold to the
     Purchasing Rightholders by the Selling Stockholder shall be reduced.

                           -------------------
under Section 3.1.3 shall be exercisable by delivering written notice of the
exercise thereof, prior to the expiration of the Option Period, to the Selling
Stockholder with a copy to the Company and the other Stockholders.  Such notice
shall state, as appropriate, (a) the number of Shares held by such Rightholder,

Section 3.1.3(a), (c) if such Rightholder is an Investor, the number of Shares
that such Investor desires to sell pursuant to Section 3.1.3(b) and (d) the
number of Shares that such Rightholder desires to sell pursuant to Sec-
tion 3.1.3(c).  The failure of a Rightholder to respond within the Option Period
to the Selling Stockholder shall be deemed to be a waiver of its, her or his
rights under Section 3.

                    3.1.5  Sale to the Purchasing Rightholders.  The closing of
                           -----------------------------------

under Section 3.1.3(a) shall be held at the principal office of the Company at

Offered Securities to the Purchasing Rightholders pursuant to Section 3.1.3(c)
shall deliver to the Purchasing Rightholders certificates representing the
Offered Securities, duly endorsed with a signature guarantee for transfer and
accompanied by all requisite transfer taxes, if any, and such Offered Securities
shall be free and clear of any liens, claims, options, charges, encumbrances or
rights ("Liens") (other than those arising hereunder), and the Selling Stock-
         -----
holder and such Stockholders who elect to participate in such sale pursuant to
Section 3.1.3(c) shall so represent and warrant, and each shall further
represent and warrant that it is the beneficial and record owner of such Offered
Securities.  Each Purchasing Rightholder shall, at the closing, deliver to the
Selling Stockholder and all other Stockholders who elect to participate in the
sale of the Offered Securities to the Purchasing Rightholders pursuant to
Section 3.1.3(c) payment in full in immediately available funds for the Offered
Securities purchased by it.  At such closing, all of the parties to the
transaction shall execute such additional documents as are otherwise necessary
or appropriate.

                    3.1.6  Sale to Third Party Offeror.   Unless the
                           ---------------------------
Rightholders elect to purchase all of the Offered Securities pursuant to
Section 3.1.3(a), the Selling Stockholder and all Investors who elect to
participate in the Third Party Offer pursuant to Section 3.1.3(b) may sell such
portions of their Shares as can be sold under Section 3.1.3(b) to the Third
Party Offeror on the terms and conditions of the Third Party Offer; provided,

Offered Securities may be made thereafter (other than to a Permitted Transferee)
by the Selling Stockholder without again offering the same to the Rightholders
in accordance with this Section 3.1.

               3.2  Sale of the Company.  If at any time following the
                    -------------------
occurrence of a Secondary Trigger Event, (i) the Investors receive a Third Party
Offer to purchase all of the Shares of the Company and all of the Investors
approve such Third Party Offer, or (ii) the Company receives a proposal to
effect a business combination with a Third Party Offeror (a "Merger Proposal")
                                                             ---------------
and the Board of Directors by a majority vote determines to accept such Merger
Proposal, then the Investors or the Board of Directors, as the case may be,
shall be entitled to deliver a written notice (the "Buyout Notice") with respect
                                                    -------------
to such Third Party Offer or Merger Proposal, as the case may be, to the other
Stockholders (in the case of any such notice delivered by the Investors) or all
of the Stockholders (in the case of any such notice delivered by the Board of
Directors) which shall state (a) the intention to effectuate such transaction,
(b) the name and address of the person or entity making the Third Party Offer or
Merger Proposal, as the case may be, and (c) the purchase price payable in
connection with such Third Party Offer or Merger Proposal.  The Buyout Notice
shall also state any other material terms and conditions of the Third Party
Offer or Merger Proposal and shall include a copy of all writings, if any,
necessary to establish the terms of such Third Party Offer or Merger Proposal. 
The Stockholders agree that, upon receipt of the Buyout Notice, they shall be
obligated to sell all of their Shares to the Third Party Offeror upon the terms
and conditions of the Third Party Offer or Merger Proposal, with the proceeds of
any such sale to be divided amongst the Stockholders as if the Company is being
liquidated (and otherwise take all necessary action to cause the Company to
consummate the proposed transaction, including voting their Shares in favor of
such sale transaction).

          The closing of any sale pursuant to this Section 3.2 shall be held at
the principal office of the Company no more than ninety (90) and no less than
ten (10) days after delivery of the Buyout Notice or at such other time and
place as the parties to the transaction may agree.

Transferred Shares as if the Involuntary Transfer had been a proposed voluntary
transfer by a Selling Stockholder, except that (a) the Option Period shall run
from the date of receipt by the Company and the Rightholders of notice of the
Involuntary Transfer, (b) the Closing Date shall be ninety (90) days after the
expiration of the Option Period, (c) such rights shall be exercised by notice to
the transferee of such Transferred Shares (the "Involuntary Transferee") rather

if such parties fail to agree as to such purchase price, the purchase price
shall be the fair market value thereof as determined in accordance with
Section 3.3.2.

                           -----------------
Transferred Shares shall be determined by a panel of three independent
appraisers, which shall be recognized investment banking firms or recognized
experts experienced in the valuation of corporations.  Within fifteen (15) days
after the notice to the Involuntary Transferee with respect to the exercise of
the right to purchase the Transferred Shares, the Involuntary Transferee and the
Board of Directors shall each designate one such appraiser that is willing and
able to conduct such determination.  If either the Involuntary Transferee or the
Board of Directors fails to make such designation within such period, the other
party that has made the designation shall have the right to make the designation
on its behalf.  The two appraisers designated shall, within a period of fif-
teen (15) days after the designation of the second appraiser, agree to designate
a third appraiser.  The three appraisers shall conduct their determination as
promptly as practicable, and the fair market value of the Transferred Shares
shall be the average of the determination of the two appraisers that are closer
to each other than to the determination of the third appraiser, which third
determination shall be discarded.  Such determination shall be final and binding
on the Involuntary Transferee and the Purchasing Rightholders.  The Involuntary
Transferee shall be responsible for the fees and expenses of the appraiser
designated by or on behalf of it and the Purchasing Rightholders shall be
responsible for the fees and expenses of the appraiser designated by or on
behalf of the Board.  The Involuntary Transferee and the Purchasing Rightholders
shall each share half the fees and expenses of the third appraiser designated by
the other appraisers.

other time and place as the parties to the transaction may agree.  At such
closing, the Involuntary Transferee shall deliver to the Purchasing Rightholders
certificates, if applicable, or other instruments or documents representing the
Transferred Shares being purchased under this Section 3.3, duly endorsed with a
signature guarantee for transfer and accompanied by all requisite transfer
taxes, if any, and such Transferred Shares shall be free and clear of any Lien
(other than that arising hereunder), including, without limitation, any Lien
arising through the action or inaction of the Involuntary Transferee, and the
Involuntary Transferee shall so represent and warrant, and shall further
represent and warrant that it is the beneficial owner of such Transferred
Shares.  Each Purchasing Rightholder shall deliver to the Selling Stockholder at
the closing payment in full in immediately available funds for such Transferred
Shares.  At such closing, all of the parties to the transaction shall execute
such additional documents as are otherwise necessary or appropriate.

                           -------
Section 3.3 shall be held to be unenforceable with respect to any particular
Involuntary Transfer, the Rightholders shall have the rights specified in
Section 3.1.3 with respect to any transfer by an Involuntary Transferee subject
to a bona fide offer from a third party for such Shares, and each Stockholder
agrees that any Involuntary Transfer shall be subject to such rights, in which
case the Involuntary Transferee shall be deemed to be the Selling Stockholder
for purposes of Section 3.1 of this Agreement and shall be bound by the
provisions of Section 3.1 and the other provisions of this Agreement.

of Shares then owned by all Stockholders participating in such purchase
(including such Stockholder's Shares).  If any Stockholder does not fully
subscribe for the number or amount of shares of capital stock or securities
convertible for or exchangeable into capital stock that it is entitled to
purchase pursuant to this Section 3.4, then each other Stockholder participating
in such purchase to the full extent provided for in the preceding sentence shall
have the right to purchase that percentage of the New Issuance not so subscribed
for, determined by dividing (a) the total number of Shares then owned by such
fully participating Stockholder by (b) the total number of Shares then owned by
all fully participating Stockholders who elect to purchase shares or other
securities pursuant to this Section 3.4 (including such Stockholder's Shares).

          The closing of any purchase pursuant to this Section 3.4 shall be held
at the time and place of the closing of, and on the same terms and conditions
as, the New Issuance, or at such other time and place as the parties to the
transaction may agree.

          4.   All Transfers in Compliance with Law and Subject to this
               --------------------------------------------------------
Agreement; Substitution of Transferee.  Notwithstanding any other provision of
- -------------------------------------
this Agreement, no transfer may be made under Sections 2.2 or 3 unless (a) each
transferee of Shares has agreed in writing to be bound by the terms and
conditions of this Agreement to the same extent and in the same manner as the
Stockholder transferring such Shares and (b) the transfer complies in all
respects with the applicable provisions of this Agreement and with applicable
federal and state securities laws including, without limitation, the Securities
Act.  Upon becoming a party to this Agreement, a transferee shall be substituted
fully for, and shall enjoy the same rights and be subject to the same obli-
gations as its predecessor hereunder, except that only a Permitted Transferee of
the Shares of Whitney shall have the rights of Whitney under Section 5, only a
Permitted Transferee of Whitney Equity Fund shall have the rights of Whitney
Equity Fund under Section 5, only a Permitted Transferee of CVCA shall have the
rights of CVCA under Section 5 and only a Permitted Transferee of a Management
Stockholder shall have the rights of such Management Stockholder under Section
5.

     and facilitate any transfer by such Stockholder of any Securities (as
     defined below) of the Company then held by such Stockholder to any

     any portion of the voting Securities then held by such Person on a share-

     Company provided for in this Agreement and with respect to such
     Stockholders' ownership of the Company's voting Securities.  Such actions
     may include, without limitation, (x) entering into such additional
     agreements as are reasonably requested by such Stockholder to permit any
     Person(s) designated by such Stockholder to exercise any voting power which
     is relinquished by such Stockholder upon any exchange of  voting Securities
     for nonvoting Securities of the Company; and (y) entering into such
     additional agreements, adopting such amendments to the Amended and Restated
     Articles of Incorporation and Bylaws of the Company and taking such
     additional actions as are reasonably requested by such Stockholder in order
     to effectuate the intent of the foregoing.

                      (b)     If a Stockholder has the right or opportunity to

     Stockholder to permit such seller to sell) such non-voting Securities on

     written request of any Stockholder made within 10 days after its receipt of
     such notice stating that after giving effect to such action such
     Stockholder would have a Voting Regulatory Problem (as defined below), the
     Company shall defer taking such action for such period (not to extend
     beyond 45 days after such Stockholder's receipt of the Company's original
     notice) as such Stockholder requests to permit it and its Affiliates to
     reduce the quantity of the Company's Securities they own or take other
     appropriate action in order to avoid the Voting Regulatory Problem.  In
     addition, the Company shall not be a party to any merger, consolidation,
     recapitalization or other transaction pursuant to which any Stockholder
     would be required to take any voting Securities, or any Securities
     convertible into, or exchangeable or exercisable for, voting Securities,

     which might reasonably be expected to cause such Stockholder to have a
     Voting Regulatory Problem.

                      (d)     In the event that any subsidiary of the Company
     ever offers to sell any of its Securities, then the Company will cause such

                           ---------------------
Stockholder agree not to amend or waive the voting or other provisions of this
Agreement or the Company's Amended and Restated Articles of Incorporation if
such amendment or waiver would cause any Stockholder to have a Voting Regulatory
Problem, provided that any such Stockholder notifies the Company that it would
have a Voting Regulatory Problem promptly after it has notice of such amendment
or waiver.  No provision of this Section 7.8 may be amended without the consent
of the Investors.

               (a)  Exercise.  This Warrant may be exercised, in whole or in
                    --------
part, by surrendering to the Company at its principal office this Warrant, with
the form of Election to Purchase Shares attached hereto as Exhibit A duly
                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

the number of shares of Class A Common Stock set forth in the Election to

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.

<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such

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

securities represented thereby, all of which taxes and expenses shall be paid by
the Company.

amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

addition to any other remedy to which such Holder may be entitled at law or in

                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such

securities represented thereby, all of which taxes and expenses shall be paid by
the Company.

               -------------------
amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such

amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such

securities represented thereby, all of which taxes and expenses shall be paid by
the Company.

          13.  Amendment or Waiver.  This Warrant and any term hereof may be
               -------------------
amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such

securities represented thereby, all of which taxes and expenses shall be paid by
the Company.

               -------------------
amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such

securities represented thereby, all of which taxes and expenses shall be paid by
the Company.

          13.  Amendment or Waiver.  This Warrant and any term hereof may be
               -------------------
amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

               (a)  Exercise.  This Warrant may be exercised, in whole or in
                    --------
part, by surrendering to the Company at its principal office this Warrant, with
the form of Election to Purchase Shares attached hereto as Exhibit A duly
                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as
                    ---------------------------------------------
practicable after surrender of this Warrant and receipt of payment the Company
shall promptly issue and deliver to the Holder a certificate or certificates for
the number of shares of Class A Common Stock set forth in the Election to
Purchase Shares, in such name or names as may be designated by such Holder,
along with a check for the amount of cash to be paid in lieu of issuance of

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-



<PAGE>







the rights or privileges of the Holder shall give rise to any liability to such
Holder as a stockholder of the Company.

          12.  Charges, Taxes and Expenses.  Issuance of certificates for shares
               ---------------------------
of Class A Common Stock upon the exercise of this Warrant shall be made without
charge to the Holder hereof for any issue or transfer tax, or other incidental
expense, in respect of the issuance or delivery of such certificates or the
securities represented thereby, all of which taxes and expenses shall be paid by
the Company.

          13.  Amendment or Waiver.  This Warrant and any term hereof may be
               -------------------
amended, waived, discharged or terminated only by and with the written consent
of the Company and the Holder.

          14.  Notices.  Any notice or other communication (or delivery)
               -------
required or permitted hereunder shall be made in writing and shall be by
registered mail, return receipt requested, telecopier, courier service or
personal delivery to the Company at its principal office at 40 Skokie Boulevard,
Northbrook, Illinois 60062-1618, and to the Holder at its address as it appears

personally delivered; when delivered by courier, if delivered by commercial
overnight courier service; five Business Days after being deposited in the mail,
postage prepaid, if mailed; and when receipt is acknowledged, if telecopied.

          15.  Certain Remedies.   The Holder shall be entitled to an injunction
               ----------------
or injunctions to prevent breaches of the provisions of this Warrant and to
enforce specifically the terms and provisions of this Warrant in any court of
the United States or any state thereof having jurisdiction, this being in
addition to any other remedy to which such Holder may be entitled at law or in
equity.

          16.  Governing Law.  This Warrant shall be governed by and construed
               -------------

                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

the number of shares of Class A Common Stock set forth in the Election to

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such
Holder as a stockholder of the Company.

                                                           ---------
executed by the Holder and accompanied by payment of the Purchase Price for the

               (b)  Delivery of Shares; Payment of Purchase Price.  As soon as

practicable after surrender of this Warrant and receipt of payment the Company

the number of shares of Class A Common Stock set forth in the Election to

<PAGE>







postal or express money order payable to the order of the Company.

               (c)  Partial Exercise.  If this Warrant is exercised for less
                    ----------------
than all of the shares of Class A Common Stock purchasable under this Warrant,
the Company shall cancel this Warrant upon surrender hereof and shall execute
and deliver to the Holder a new Warrant of like tenor for the balance of the
shares of Class A Common Stock purchasable hereunder.

               (d)  When Exercise Effective.  The exercise of this Warrant shall
                    -----------------------
be deemed to have been effective immediately prior to the close of business on
the Business Day on which this Warrant is surrendered to and the Purchase Price
is received by the Company as provided in this Section 2 (the "Exercise Date"),
                                                               -------------
and the Person in whose name any certificate for shares of Class A Common Stock
shall be issuable upon such exercise, as provided in Section 2(b), shall be
deemed to be the record holder of such shares of Class A Common Stock for all
purposes on the Exercise Date.

          3.   Adjustment of Purchase Price and Number of Shares.  The Purchase
               -------------------------------------------------
Price and the number of shares of Class A Common Stock issuable upon exercise of
this Warrant shall be adjusted from time to time upon the occurrence of the
following events:

               (a)  Dividend, Subdivision, Combination or Reclassification of
                    ---------------------------------------------------------
Common Stock.  If the Company shall, at any time or from time to time, (i)
- ------------
declare a dividend on the Common Stock payable in shares of its capital stock
(including Common Stock), (ii) subdivide the outstanding Common Stock,
(iii) combine the outstanding Common Stock into a smaller number of shares, or
(iv) issue any shares of its capital stock in a reclassification of the Common
Stock (excluding any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then in each such
case, the Purchase Price in effect at the time of the record date for such
dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock issuable on
such date shall be proportionately adjusted so that the Holder of any Warrant
exercised after such date shall be entitled to receive, upon payment of the same
aggregate amount as would have been payable before such date, the aggregate
number and kind of shares of capital stock which, if such Warrant had been
exercised immediately prior to such date, such Holder would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  Any such adjustment shall become effective
immediately after the record date of such dividend or the effective date of such
subdivision, combination or reclassification.  Such adjustment shall be made
successively whenever any event listed above shall occur.  If a dividend is
declared and such dividend is not paid, the Purchase Price shall 






























                                       -5-



<PAGE>







again be adjusted to be the Purchase Price in effect immediately prior to such
record date.

               (b)  De Minimis Adjustments.  No adjustment in the Purchase Price
                    ----------------------
shall be made if the amount of such adjustment would result in a change in the
Purchase Price per share of less than $.01, but in such case any adjustment that
would otherwise be required to be made shall be carried forward and shall be
made at the time of and together with the next subsequent adjustment, which
together with any adjustment so carried forward, would result in a change in the
Purchase Price of $.01 per share.  If the Company shall, at any time or from
time to time, issue Common Stock by way of dividends on any stock of the Company
or subdivide or combine the outstanding shares of the Common Stock, such amount
of $.01 (as theretofore increased or decreased, if such amounts shall have been
adjusted in accordance with the provisions of this clause) shall forthwith be
proportionately increased in the case of a combination or decreased in the case
of a subdivision or stock dividend so as appropriately to reflect the same. 
Notwithstanding the provisions of the first sentence of this Section 3(b), any
adjustment postponed pursuant to this Section 3(b) shall be made no later than
the earlier of (i) six months from the date of the transaction that would, but
for the provisions of the first sentence of this Section 3(b), have required
such adjustment or (ii) an Exercise Date.

          4.   Reorganization, Reclassification, Merger and Sale of Assets.  If
               -----------------------------------------------------------
there occurs any capital reorganization or any reclassification of the Common
Stock of the Company, the consolidation or merger of the Company with or into
another Person (other than a merger or consolidation of the Company in which the
Company is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Company to
another Person, then the Holder will thereafter be entitled to receive, upon the
exercise of this Warrant in accordance with the terms hereof, the same kind and
amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock
of the Company upon such reorganization, reclassification, consolidation,
merger, sale or conveyance, in respect of that number of shares of Class A
Common Stock then deliverable upon the exercise of this Warrant if this Warrant
had been exercised immediately prior to such reorganization, reclassification,
consolidation, merger, sale or conveyance.

          5.   Certificate as to Adjustments.  Whenever the Purchase Price and
               -----------------------------
the number of shares of Class A Common Stock issuable, or the securities or
other property deliverable, upon the exercise of this Warrant shall be adjusted
pursuant to the provisions hereof, the Company shall promptly give written
notice thereof to the Holder, in accordance with Section 14, in the form 






























                                       -6-



<PAGE>







of a certificate signed by the Chairman of the Board, President or one of the
Vice Presidents of the Company, and by the Chief Financial Officer, Treasurer or
one of the Assistant Treasurers of the Company, stating the adjusted Purchase
Price, the number of shares of Class A Common Stock issuable, or the securities
or other property deliverable, upon exercise of the Warrant calculated to the
nearest cent or the nearest one one-hundredth of a share and setting forth in
reasonable detail the method of calculation and the facts requiring such
adjustment and upon which such calculation is based.  Each adjustment shall
remain in effect until a subsequent adjustment is required.

          6.   Fractional Shares.  Notwithstanding an adjustment in the number
               -----------------
of shares of Class A Common Stock covered by this Warrant or any other provision
of this Warrant, the Company shall not be required to issue fractions of shares
upon exercise of this Warrant or to distribute certificates which evidence frac-
tional shares.  In lieu of fractional shares, the Company may make payment to
the Holder, at the time of exercise of this Warrant as herein provided, of an
amount in cash equal to such fraction multiplied by the Current Market Price of
a share of Class A Common Stock on the Exercise Date.

          7.   Notice of Proposed Actions.  In case the Company shall propose at
               --------------------------
any time or from time to time (a) to declare or pay any dividend payable in
stock of any class to the holders of Common Stock or to make any other
distribution to the holders of Common Stock (other than a regularly scheduled
cash dividend), (b) to offer to the holders of Common Stock rights or warrants
to subscribe for or to purchase any additional shares of Common Stock or shares
of stock of any class or any other securities, rights or options, to effect any
reclassification of its Common Stock, (d) to effect any consolidation, merger or
sale, transfer or other disposition of all or substantially all of the property,
assets or business of the Company which would, if consummated, adjust the
Purchase Price or the securities issuable upon exercise of the Warrants, or (e)
to effect the liquidation, dissolution or winding up of the Company, then, in
each such case, the Company shall give to the Holder, in accordance with Section
14, a written notice of such proposed action, which shall specify (i) the record
date for the purposes of such stock dividend, distribution of rights or
warrants, or if a record is not to be taken, the date as of which the holders of
shares of Common Stock of record to be entitled to such dividend, distribution
of rights or warrants is to be determined, or (ii) the date on which such
reclassification, consolidation, merger, sale, transfer, disposition, liquida-
tion, dissolution or winding up is expected to become effective, and such notice
shall be so given as promptly as possible but in any event at least five (5)
Business Days prior to the applicable record, determination or effective date
specified in such notice.
































                                       -7-



<PAGE>








          8.  No Dilution or Impairment.  The Company will not, by amendment of
              -------------------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this Warrant, but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the rights of the
Holder of this Warrant against dilution or other impairment.  Without limiting
the generality of the foregoing, the Company (a) will not increase the par value
of any shares of stock receivable on the exercise of this Warrant above the
amount payable therefor on such exercise, (b) will at all times reserve and keep
available the maximum number of its authorized shares of Class A Common Stock,
free from all preemptive rights therein, which will be sufficient to permit the
full exercise of this Warrant, and will take all such action as may be necessary
or appropriate in order that all shares of Class A Common Stock as may be issued
pursuant to the exercise of this Warrant will, upon issuance, be duly and
validly issued, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof.

          9.  Replacement of Warrants.  On receipt by the Company of an
              -----------------------
affidavit of an authorized representative of the Holder stating the
circumstances of the loss, theft, destruction or mutilation of this Warrant (and
in the case of any such mutilation, on surrender and cancellation of such
Warrant), the Company at its expense will promptly execute and deliver, in lieu
thereof, a new Warrant of like tenor; provided, however, that in the case of
loss, destruction or theft, the Board of Directors of the Company may in its
discretion require the Holder to indemnify the Company and give the Company a
bond, in such sum and in such form and with such surety or sureties as it may
direct.

          10.  Transfer.  Subject to the transfer conditions referred to in the
               --------
legend endorsed hereon and the transfer restrictions set forth in the
Stockholders' Agreement, this Warrant and all rights hereunder are
transferrable, in whole or in part, without charge to the Holder hereof upon
surrender of this Warrant with a properly executed Form of Assignment attached
hereto as Exhibit B at the principal office of the Company.  Upon any partial
          ---------
transfer the Company will, at its expense, issue and deliver to the Holder a
Warrant of like tenor in the name of the Holder, which shall be exercisable for
such number of shares of Class A Common Stock with respect to which rights under
this Warrant were not so transferred.

          11.  No Rights or Liability as a Stockholder.  This Warrant does not
               ---------------------------------------
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
the Holder hereof to purchase Class A Common Stock, and no enumeration herein of




























                                       -8-

the rights or privileges of the Holder shall give rise to any liability to such
Holder as a stockholder of the Company.

amended, waived, discharged or terminated only by and with the written consent

          of the validity or merit of any claim or defense of Medicon.

     5.   This agreement is binding on the Parties and on each and all of their
          respective assigns and successors in interest.

          belief and knowledge of the nature, extent and duration of the claims
          of Affiliated, and of the claims and defenses of Medicon, and that
          they have not been influenced to any extent whatsoever in entering
          into this Agreement by any representations or statements regarding
          said claims or defenses, or regarding any other matters made by the
          persons, firms, or corporations who are hereby released, or by any
          person or persons representing them.

     7.   Affiliated and Medicon each warrant that it is the owner of any claims
          or defenses that are released herein, and represents that it has not
          assigned or transferred any such claims or defenses to any other party
          or person.

     8.   Affiliated and Medicon each acknowledge that it has carefully read
          this Agreement and knows the contents hereof, and it signs the
          Agreement as its free act and intends to be legally bound hereby.

     9.   This Agreement constitutes the entire understanding of the parties
          with respect to the satisfaction, compromise and release of any and

     By agreement of the Parties, and it appearing that the Parties have entered
into a compromise  in settlement of  this matter including  the terms set  forth
herein, and the Court otherwise being sufficiently advised,
     IT IS HEREBY ORDERED:
     1.   Commencing June 16, 1996, defendant Medicon, Inc. ("Medicon"), and its
officers,  agents,  servants,  employees,  parent  or  subsidiary  corporations,
successors, and any other persons or entities in active concert or participation
with them, are enjoined from making  any use, or reference to any prior  use, of
the term MEDICON or  any other designation confusingly similar to MEDECON, shall
place no  advertisements in the publications  of others using the  MEDICON name,
and  shall  not use  "MEDICON" or  "formerly  MEDICON" in  direct mail  or other
advertising pieces or on sales calls.
     2.   Medicon shall no later  than June 15, 1996 remove,  replace or obscure
any reference to MEDICON or any  other confusingly similar designation from  its
facilities,  marketing materials, advertising  or other publications,  and other
documents.
     3.   Medicon  shall commence utilization of a  new name, which shall not be
confusingly  similar to MEDECON, no later than June 15, 1996.
     4.   Notwithstanding  the foregoing, Medicon may make the following limited
use of the MEDICON name after June 15, 1996:
          a.   Medicon  may  inform  its currently  existing  customers, service
               providers,  banks, insurance companies,  and other  entities with
               which  Medicon  currently  does business,  that  the  newly named
               company  was "formerly Medicon,  Inc." to and  including December
               15, 1996;
          b.   Medicon may  at any  time identify  itself as "formerly  Medicon,
               Inc." when doing so is legally necessary, but only to the limited
               extent so necessary, to allow Medicon to 


















<PAGE>
               conduct its business, such as where such use is required for
               Medicon's dealings with Medicare, Medicaid, state and federal
               regulatory agencies, health departments, or state insurance
               departments; and
          c.   Medicon may continue to use existing printed materials bearing
               the MEDICON mark to such and including September 15, 1996, but
               after June 15, 1996 shall use materials only with existing
               customers and service providers with which Medicon currently
               does business.
     5.   This action is dismissed with prejudice without costs to either of the
parties; however, the Court shall retain jurisdiction to monitor performance of
this Consent Decree and to adjudicate any disputes arising hereunder or under
the Settlement Agreement between MedEcon and Medicon dated May 14, 1996.

                           EARMARKING LETTER AGREEMENT


          EARMARKING LETTER AGREEMENT, dated as of March 12, 1996, between
Medicon, Inc. ("Medicon") and ChoiceCare Health Plans, Inc. ("ChoiceCare").

          WHEREAS, Medicon and ChoiceCare are parties to that certain Diagnostic
Imaging Services Agreement for HMO, effective as of April 1, 1995 (the
"ChoiceCare Agreement"), pursuant to which Medicon receives monthly payments in
exchange for providing the services described in the ChoiceCare Agreement;

          WHEREAS, pursuant to the ChoiceCare Agreement, Medicon is responsible
for utilizing the monthly payments to make payments to (i) PRP's (as defined in
the ChoiceCare Agreement) for imaging services rendered to persons enrolled in
ChoiceCare's prepaid health care plans and healthcare plans administered by
ChoiceCare, (ii) ChoiceCare and (iii) ChoiceCare self-funded customers
(collectively, "Provider Payments"); and

          WHEREAS, J.H. Whitney, & Co. ("JHW") and Chemical Venture Capital
Associates, L.P. ("CVCA," and together with JHW, the "Lenders") have made an
earmarking loan (the "Provider Payment Loan") in the aggregate principal amount
of $6,000,000 to Medicon that has been earmarked so that Medicon may pay a
liability owing to ChoiceCare for Provider Payments arising under the ChoiceCare
Agreement.

          NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth herein and for good and valuable consideration, the receipt
and adequacy of which is hereby acknowledged, the parties hereto agree as
follows:

          1.   Medicon hereby warrants and represents to ChoiceCare that Medicon
has taken appropriate steps to segregate the proceeds of the Provider Payment
Loan from the Lenders in a separate account pending execution of this Agreement
and that Medicon has no control, nor has it ever had control, except to the
extent of segregation of the proceeds, over the funds made available through the
Provider Payment Loan.

          2.   Concurrently with the execution and delivery hereof, Medicon
shall, by wire transfer of immediately available funds and as directed by the
Lenders, transfer the proceeds of the Provider Payment Loan to ChoiceCare, all
of which funds shall be the exclusive property of ChoiceCare and shall be under
the exclusive dominion and control of ChoiceCare (such funds, together with the
portion of the payment retained by ChoiceCare, as described in paragraph 3
hereof, shall, as adjusted from time to time pursuant to paragraph 4 hereof, be
referred to herein as the "ChoiceCare Payment").  Upon receipt of the ChoiceCare
Payment, ChoiceCare agrees that Medicon's financial liability under the
ChoiceCare Agreement for the Provider Payments shall be reduced by the amount of
the ChoiceCare Payment, as adjusted from time to time.  It is hereby 



















<PAGE>
                                                                        2




acknowledged and agreed that the amount of the ChoiceCare Payment shall
fluctuate as it is reduced by the amount of the Yearly Reconciliation (as
defined herein) for the contract year ended March 31, 1995 and subsequent
contract years,  and adjusted from time to time pursuant to paragraph 4
hereof.  Medicon hereby waives its right to seek to avoid and recover from
ChoiceCare the ChoiceCare Payment under chapter 5 of title 11 of the United
States Code in the event that Medicon voluntarily commences a case under
chapter 7 or chapter 11 of the Bankruptcy Code or an involuntary case is
commenced against Medicon under chapter 7 or chapter 11 of the Bankruptcy Code.

          3.   Immediately following receipt of the ChoiceCare Payment,
ChoiceCare shall, by wire transfer of immediately available funds, deposit into
an account designated by Medicon $2,964,908.90 (which equals the amount required
to be paid to Medicon for February, 1996 ($1,550,005.90) and March, 1996
($1,614,903.00), in each case under the ChoiceCare Agreement), less $200,000
which is being retained by ChoiceCare to reduce Medicon's financial liability
under the ChoiceCare Agreement for the Provider Payments. It is further agreed
that ChoiceCare shall continue to make payments to Medicon in accordance with
the terms of the ChoiceCare Agreement or any successor agreement thereto. 
ChoiceCare and Medicon specifically agree that the  payment referred to in this
paragraph 3 and any other subsequent payment made by ChoiceCare to Medicon under
this Agreement, the ChoiceCare Agreement or any subsequent agreements, shall
constitute new value to Medicon.

          4.   Within 45 days after each March 31, June 30, September 30 and
December 31 during the term of the ChoiceCare Agreement or any successor
thereto, Medicon shall use its best efforts to prepare in good faith and provide
to ChoiceCare a statement, the form of which is attached hereto as Exhibit A 
(the "Statement"), containing reasonable detail and setting forth a calculation
of the amount (the "Payout Amount") necessary to make the payment of funds for
the settlement and reconciliation of reserves on a once per contract year basis
(the "Yearly Reconciliation"), if any, and the Provider Payments as if the
contractual relationship between Medicon and ChoiceCare were terminated as of
such March 31, June 30, September 30 or December 31.  ChoiceCare shall be
entitled, for a period of 10 days following delivery of the Statement, to reject
such Statement if it is acting reasonably and in good faith.  If ChoiceCare,
acting in accordance with the previous sentence, rejects the Statement delivered
by Medicon, the parties shall cooperate and work together to prepare a Statement
that is mutually agreeable.

          Within 10 days after delivery of a Statement that is prepared and
agreed to in accordance with the preceding paragraph:

               (a)  if the Payout Amount is less than the amount of the
ChoiceCare Payment, as adjusted from time to time, ChoiceCare shall transfer the
amount by which the ChoiceCare Payment exceeds the Payout Amount to an account
designated by Medicon; or















<PAGE>
                                                                        3



               (b)  if the Payout Amount is greater than the ChoiceCare Payment,
as adjusted from time to time, Medicon shall pay to ChoiceCare the amount by
which the Payout Amount exceeds the ChoiceCare Payment.

          It is further agreed that if following termination of the contractual
relationship between Medicon and ChoiceCare, the amount of the ChoiceCare
Payment, as adjusted from time to time, (i) exceeds the amount necessary to make
final payment of all Yearly Reconciliations and all Provider Payments, the
excess of such ChoiceCare Payment which is due and payable to Medicon shall be
transferred by ChoiceCare to an account designated by Medicon or (ii) is less
than the amount necessary to make final payment of all Yearly Reconcilations and
all Provider Payments, the deficit of such ChoiceCare Payment which is due and
payable to ChoiceCare or ChoiceCare self funded customers or PRPs shall be
transferred by Medicon to an account designated by ChoiceCare.

          In the event that it is determined pursuant to an audit, whether
performed by ChoiceCare or a third party, that the amount of the ChoiceCare
Payment, as adjusted, and the Payout Amount differ by more than $10,000, the
parties agree to pay the difference, through the mechanisms set forth in
paragraph 4 of this Agreement, within ten (10) business days of receipt of
written notice of such difference.

          5.   Except with respect to Medicon's obligation to fund adjustments
to the ChoiceCare Payment pursuant to paragraph 4(b) hereof or in the event of
(i) a Termination Event and compliance by ChoiceCare with paragraph 6(a) or
(ii) termination of the ChoiceCare Agreement or any successor agreement thereto
and non-compliance by Medicon with the terms and provisions of paragraph 7
hereof, ChoiceCare hereby fully, finally and forever waives, releases and
discharges Medicon and its predecessors, subsidiaries, parent companies,
divisions, affiliated corporations, successors and assigns and any or all of
them from any and all financial liability for Provider Payments under the
ChoiceCare Agreement or any successor agreement, to the full extent of the
amount of the ChoiceCare Payment, as adjusted. Notwithstanding the foregoing,
ChoiceCare shall not release Medicon and its predecessors, subsidiaries, parent
companies, divisions, affiliated corporations, successors or assigns from any
obligations or liabilities to process or make Provider Payments under the
ChoiceCare Agreement or any successor agreement, or from the financial liability
for Provider Payments to the extent such financial liability exceeds the amount
of the ChoiceCare Payment.

          6.   Upon a Termination Event: 

               (a)  ChoiceCare shall promptly pay the amount of the ChoiceCare
Payment, as adjusted, to Medicon; and 

               (b)  Following the payment by ChoiceCare specified in
paragraph 6(a), Medicon shall re-assume financial liability for and remain
responsible for (I) the making of Provider Payments and (II) Yearly
Reconciliations.

          7.
               Upon the later of and in the event that a Termination Event has
not occurred, (a) the termination of the ChoiceCare  Agreement or (b) if a
successor agreement to the ChoiceCare Agreement is entered into, upon the
termination of such successor agreement, ChoiceCare shall promptly pay to
Medicon the amounts due under such agreement for the dates of service through
the termination of such agreement as said amounts become payable to the
ChoiceCare PRP's.  In connection therewith, Medicon shall provide to ChoiceCare
the explanations of payment, or a summary thereof ("EOPs") identifying the
ChoiceCare PRP's to receive payment and the amount(s) to be paid to each
ChoiceCare PRP.  In addition, prior to the disbursement of any additional funds
to Medicon to be paid to the ChoiceCare PRP's, Medicon shall provide ChoiceCare
with written certification that any and all prior funds advanced by ChoiceCare
to Medicon pursuant to this paragraph 7 have been paid by Medicon to the
ChoiceCare PRP's in accordance with the EOPs previously provided to ChoiceCare. 
Medicon agrees that it shall be solely responsible for the making of the
Provider Payments pursuant to this paragraph 7 and shall indemnify ChoiceCare
for any use of said funds not in accordance with the EOPs provided to
ChoiceCare.

          8.   Upon execution and delivery hereof, the parties acknowledge that
they will enter into good faith negotiations relating to terminating the
ChoiceCare Agreement and replacing it with a successor agreement.  The parties
agree that if they have not mutually terminated the ChoiceCare Agreement and
entered into a successor agreement thereto or amended the ChoiceCare Agreement
upon mutually agreeable terms on or before ten days after receipt of the
ChoiceCare Payment by ChoiceCare, or such other time as may be agreed to by the
parties, each of ChoiceCare and Medicon shall have the right, with five days'
written notice, to terminate the ChoiceCare Agreement; provided, however, that
Medicon and ChoiceCare shall promptly commence discussions to agree upon an
appropriate wind-up period following termination of the ChoiceCare Agreement.

          9.
               As used in this Agreement, the following terms have the following
meanings unless the context otherwise requires:

          "Current Liabilities"  shall mean, at any date, the aggregate of the
           -------------------
current liabilities of Medicon and its subsidiaries on a consolidated basis as
of such date, as determined in accordance with Generally Accepted Accounting
Principles.

          "Generally Accepted Accounting Principles" shall mean generally
           ----------------------------------------
accepted accounting principles, as recognized by the American Institute of
Certified Public Accountants, consistently applied and maintained on a
consistent basis for Medicon and its subsidiaries on a consolidated basis
throughout the period indicated.

          "Quick  Ratio" shall mean, at a quarter-end date, the ratio of the
           ------------
cash and cash equivalents of Medicon to the Current Liabilities of Medicon, as
computed from amounts as filed by Medicon with the Securities and Exchange
Commission (such as on Form 10-Q or 10-K) or on internally prepared financial
statements of Medicon.

          "Termination Event" shall mean a certification by Medicon's Chief

Financial Officer to ChoiceCare that, as of the date of such certification, the
Quick Ratio of Medicon has been in excess of 1:1 for two consecutive fiscal
quarters. 

          10.  This Agreement and the ChoiceCare Agreement contain the entire
agreement among the parties with respect to the subject matter hereof, and such
agreement supersedes all prior agreements, written or oral, whether binding or
non-binding, among any of the parties hereto, with respect to the subject matter
hereof.  No representations, warranties or inducements have been  made to the
parties hereto or their counsel concerning this Agreement and the agreements
related hereto other than those representations, warranties and covenants
contained herein and in the agreements related hereto.  No waiver, modification
or amendment of the terms of this Agreement shall be valid unless in writing
signed by the party to be charged and only to the extent therein set forth.  Any
failure by any party to insist upon the strict performance by any other party of
any of the provisions of this Agreement shall not be deemed a waiver of any of
the provisions hereof or thereof, and such party, notwithstanding such failure
shall have the right thereafter to insist upon the strict performance of any and
all of the provisions hereof or thereof to be performed by such other party.

          11.  ChoiceCare covenants and agrees that, after the date of this
Agreement, it shall not, and ChoiceCare will take reasonable steps to cause each
of its affiliates not to, take any action or make any statement, whether or not
in writing, that disparages or denigrates Medicon or its affiliates, agents,
employees, officers or directors (including, without limitation, by way of news
interview or the expression of personal views, opinions or judgments to the news
media); and Medicon covenants and agrees that, after the date of this Agreement,
it shall not, and Medicon will take reasonable steps to cause each, of its
agents, employees, officers or directors and all affiliates of Medicon not to
take any action or make any statement, whether or not in writing, that
disparages or denigrates ChoiceCare (including, without limitation, by way of
news interview or the expression of personal views, opinions or judgments to the
news media); provided, however, that if ChoiceCare or Medicon violates any
             --------  -------
provision of this paragraph 11, the other shall be relieved of his or its
obligations under this paragraph 11 to the extent necessary to respond to such
violation.  Notwithstanding the foregoing, however, nothing contained in this
paragraph 11 shall prohibit either party (the "Disclosing Party") from
disclosing the facts and circumstances surrounding the transactions contemplated
by this Agreement and the ChoiceCare Agreement, or any subsequent agreement
thereto, if required by law, the Securities and Exchange Commission or any other
administrative, governmental or regulatory agency or if the Disclosing Party
considers it necessary to include in any Securities and Exchange Commission or
other regulatory filings in order not to omit to state a material fact (the
determination of what constitutes a material fact to be made by the Disclosing
Party in its good faith judgement and in its sole discretion) or to cause a fact
stated not to be misleading (the determination of what will cause a stated fact
to be misleading to be made by the Disclosing Party in its good faith judgement
and in its sole discretion).

          12.  In making decisions with respect to the Provider Payment Loan,
the ChoiceCare Payment and in making the decision to enter into this Agreement,
or in taking any other actions related to or in connection with this Agreement,
and/or the ChoiceCare Agreement, ChoiceCare shall not be deemed to be in control
of the operations of Medicon or to be acting as a "responsible person" with
respect to the operation(s) and/or management of Medicon and shall have no
liability as a controlling or responsible person with respect to the
operation(s) and/or management of Medicon.

          13.  Medicon agrees to promptly provide to ChoiceCare audited

1996, a statement for the settlement of the ChoiceCare Agreement for the
contract year ending March 31, 1995.   It is acknowledged and agreed that an
estimate of the settlement amount has been included in the ChoiceCare Payment.

          15.  As further consideration for the parties entering into this
Agreement and as an additional fee under the ChoiceCare Agreement, or any
subsequent agreement thereto, until there occurs a Termination Event or the
amount of the ChoiceCare Payment has been reduced to zero in accordance with the
provisions of paragraphs 4 and 7 hereof, ChoiceCare agrees to pay to Medicon, on
a quarterly basis, an amount equal to interest on the amount of the ChoiceCare
Payment, as adjusted, calculated using the 30-day rate (as published in the Wall
Street Journal) on high grade commercial paper in effect on the first day of
each quarter for which interest is to be paid. 

          16.  All notices and other communications hereunder shall be  made in
writing and shall be by telecopier, courier service or personal delivery in
accordance with the notice provisions of the ChoiceCare Agreement or any
successor agreement thereto.

     17.This Agreement shall be governed by and construed in accordance with the
laws of the State of Ohio, without regard to the principles of the conflicts of
law of such State.

Period and the Second Abatement Period, and such appropriate amounts shall be
due and payable on the first day after the end of each of the First Abatement

and Tenant's obligation to make payments of Base Rent, Operating Cost Share 
Rent, and Tax Share Rent after the First Abatement Period shall commence

Abatement Period; and the Second abatement Period shall be deemed to consist 
of the initial partial calendar month, plus the next six consecutive calendar 
months, provided that only the following portion of the sixth full calendar 
month shall be included: there shall be included with respect to such sixth 
full calendar month, the number of days in such month so that the sum of such 
number plus the number of days in the first partial calendar month of the Second
Abatement Period shall equal 31 days, and Tenant's obligation to make payments 
of Base Rent, Operating Share Cost Rent, and Tax Share Rent after the Second

CONTINUATION OF SECTION 2A(1).
- -----------------------------

     If, at any time during either of the First Abatement Period or the Second
Abatement Period, Tenant shall be in default under the Lease, which default is
not cured within the applicable cure period set forth in Section 11A below, any
rights granted to Tenant under this Section 2A (1) of the Lease shall cease
during the period during which such default continues and shall not recommence
until such default is cured (the "Cessation Period"), and Tenant shall be
                                 -------------------
obligated to pay and shall be liable for any and all portions of Base Rent
falling due or accruing during such Cessation Period, together with any other
amounts due under this Lease. Any cessation of rights pursuant too this Section
2A (1) shall not in any way extend the length of either of the First Abatement
Period or the Second Abatement Period in the event that such cessation is caused
by a material default. On the other hand, if a cessation is caused by a non-
material default and Tenant timely cures such default, then the affected
Abatement Period shall be extended on a per diem basis for the number of days of
such Cessation Period.

will generally (but need not) be issued after the beginning of a fiscal year and
revised upon the determination of the final real estate tax assessment or final
real estate tax rate for the Project.

     Within  ten (10) days after notice  from Landlord setting forth an estimate
of Operating Costs  for a particular fiscal  year, Tenant shall pay  Landlord an
amount equal  to one-twelfth  (1/12th) of Tenant's  Proportionate Share  of such
estimated costs multiplied  by the number  of months that  have elapsed in  such
fiscal year to the date of  such payment, minus payments of estimated  Operating
Cost Share Rent previously paid for said  period. Thereafter on the first day of
each month, Tenant shall pay monthly until a new estimate of  Operating Costs is
applicable,   one-twelfth  (1/12th)  of  Tenant's  Proportionate  Share  of  the
estimated Operating Costs.

     Within ten (10) days  after notice from Landlord setting forth  an estimate
of Taxes for a particular fiscal year, Tenant shall pay Landlord an amount equal
to one-twelfth (1/12th) of Tenant's  Proportionate Share of such estimated Taxes
multiplied by the number of months that have elapsed in such fiscal year to  the
date of such payment, minus payments of estimated Tax Share Rent previously paid
for said  period. Thereafter on the  first day of  each month, Tenant  shall pay
monthly  until a new  estimate of Taxes  is applicable, one-twelfth (1/12th) of
Tenant's Proportionate Share of the estimated Taxes.

     (2)  Correction  of Operating  Cost  Share  Rent.  As  soon  as  reasonably
          -------------------------------------------
possible after the end of each  fiscal year, Landlord shall deliver to Tenant  a
report  (the "Operating  Cost Report")  setting forth  (a) the  actual Operating
Costs for the preceding fiscal year, (b) the amount of Operating Cost Share Rent
due to Landlord for such  preceding fiscal year, and (c) the amount of Operating
Cost Share Rent paid by the Tenant in and allocable  to such  fiscal year. On or
before twenty  (20)  days after  receipt of  such report,  Tenant  shall pay  to
Landlord the amount  of Operating Cost Share  Rent due for the  preceding fiscal
year (or a portion thereof if this Lease was not in effect for the entire fiscal
year) minus  any  payments made  by Tenant  for such  fiscal  year. If  Tenant's
estimated payments of Operating  Cost Share Rent exceed the  amount due Landlord
for the  fiscal year  in question,  Landlord shall apply  any such  amount as  a
credit against Tenant's  other obligations under this  Lease, or if the Term has
expired or this Lease has been terminated and Tenant has no  further obligations
under  this Lease  (including any  obligations which  survive the  expiration or
termination of  this  Lease), then  Landlord  shall refund  any  such amount  to
Tenant.

     (3)  Correction of Tax  Share Rent. At any time during any fiscal year when
          -----------------------------
such information  becomes available, Landlord  shall deliver to Tenant  a report
(the "Tax Report") setting  forth (a) the actual Taxes for  the preceding fiscal
year, (b) the amount of Tax Share Rent due to Landlord for such preceding fiscal
year, and (c) the  amount of Tax Share Rent paid by the  Tenant in and allocable
to such fiscal year. On or before twenty (20) days after receipt of such report,
Tenant shall pay to Landlord the amount of  Tax Share Rent due for the preceding
fiscal year (or a portion thereof if this Lease was not in effect for the entire
fiscal year) minus any payments made for such fiscal year. If Tenant's estimated
payments of Tax Share Rent














                                       -3-

<PAGE>
exceed the  amount due Landlord for the fiscal  year in question, Landlord shall
apply any such amount as a credit  against Tenant's other obligations under this
Lease, or if the Term has expired or this Lease  has been terminated and Tenant
has no further obligations under this Lease (including any obligations  which 
survive the expiration or  termination of this Lease), then Landlord shall 
refund any such amount to Tenant.

C.   Definitions:
     -----------

     (1)  Taxes.    "Taxes"  shall mean  any and  all federal,  state  and local
          -----
governmental taxes, assessments and charges  of  any  kind or  nature,  whether
general, special, ordinary or extraordinary,  which Landlord shall pay or become
obligated  to pay  because  of or  in connection  with  the ownership,  leasing,
renting, management, control  or operation  of the  Project or  of the  personal
property,  fixtures, machinery, equipment, systems and apparatus located therein
or used in  connection therewith. Taxes shall include,  without limitation, real
estate taxes, personal  property  taxes, sewer  rents, water rents, assessments,
(special or otherwise),  transit taxes  and ad valorem  taxes. Taxes shall  also
include  all fees, costs and expenses (including, without limitation, legal fees
and court costs) paid by  Landlord in connection with protesting or  contesting,
or seeking a refund  or reduction of, any of the aforesaid  Taxes, regardless of
whether the Landlord  is ultimately successful. If  at any time during  the term
hereof, a tax or excise on rents  or income or other tax however described  (the
"Rent Tax") is levied or assessed by the United States or the State of Illinois,
or any political subdivision  thereof, on account of the rents  hereunder or the
interest of  Landlord under this  Lease, such Rent  Tax shall constitute  and be
included in Taxes, provided, however, that in no event shall Tenant be obligated
(a) to pay  for any year any  greater amount as a  result of such Rent  Tax than
would have been payable  by Tenant had  the rentals paid  to Landlord under  all
Project leases (being  the rentals upon which  such taxes are imposed)  been the
sole taxable income  of Landlord for  the year in question  or (b) to pay  or to
reimburse Landlord for  any tax of any kind assessed against Landlord on account
of any such Rent Tax  having been reimbursed to Landlord by Tenant  or any third
party.

     For the purpose of determining Taxes for any given fiscal year,  the amount
to  be  included for  such fiscal  year  (a) from  special taxes  or assessments
payable in  installments,  shall be  the  amount of  the  installments (and  any
interest)  due and payable  during such fiscal  year, (b) from  all other Taxes,
shall be the amount accrued, assessed or  otherwise imposed for such fiscal year
without regard to when any such Taxes  are payable, and (c) from any  adjustment
(including, without limitation, a refund) to any Taxes  by the taxing authority,
when such adjustment has resulted in a corresponding adjustment payment by or to
Landlord, shall constitute an adjustment to Taxes for the fiscal year during 
which such adjustment is made or received by Landlord, as the case may be.

     Taxes shall not  include any  net income  (except Rent  Tax as  hereinabove
provided), capital,  stock, succession,  transfer, franchise,  gift, estate   or
inheritance taxes,  unless the  same  shall be  imposed in  lieu of  all or  any
portion of Taxes.














                                       -4-

<PAGE>

     (2)  Operating Costs.    "Operating Costs"  shall mean any  expenses, costs
          ---------------
and disbursements (other than Taxes) of every  kind and nature, paid or incurred
by Landlord in connection with  the ownership, leasing, management, maintenance,
operation and repair of all or any part of the Project (adjusted for vacancy  as
hereafter  provided)  and  of  the  personal  property,  fixtures,  machinery,
equipment, systems and apparatus  located in the  Project or used in  connection
therewith. Operating  Costs shall not include (a) costs of alterations of tenant
premises; (b) costs of capital improvements, except for any capital improvements
which are intended to reduce Operating Costs, and any capital improvements which
Landlord is required to make pursuant to, or which Landlord shall deem necessary
to keep the  Project in compliance  with, all applicable governmental  rules and
regulations applicable from time  to time to the Project  (the foregoing capital
improvements that are included within Operating Costs  are collectively referred
to herein  as the  "Included Capital  Items"); (c)  depreciation (except  on any
Included Capital Items);  (d) interest and principal  payments on mortgages   or
any rental payments  on any ground or  other underlying leases subject  to which
Landlord  holds  its   interest  in  the   Project  (hereinafter,  referred   to
individually as a "Ground Lease" and collectively as "Ground Leases"), and other
debt  costs,   if  any;  (e)   real  estate  brokers'  leasing   commissions  or
compensations;  (f) any  cost  or  expenditure (or  portion  thereof) for  which
Landlord is  reimbursed, whether by  insurance proceeds or  otherwise (Operating
Cost  Share Rent and  Tax Share Rent provided  for in any  tenant leases are not
reimbursements); (g) the  cost of  any kind  of service furnished  to any  other
office tenant of  the Project which Landlord  does not make available  to Tenant
hereunder*.

     If during all or  any portion of any  fiscal year the Project is  not fully
rented and  occupied  by tenants,  Landlord  may elect  to  make an  appropriate
adjustment of Operating  Costs for such fiscal year,  employing sound accounting
and management principles, to determine the Operating Costs that would have been
paid or incurred by Landlord had the  Project been fully rented and occupied for
the  entire fiscal year,  and the amount  so determined shall  be deemed to have
been the Operating Costs for such fiscal year. If Landlord is not furnishing any
particular  work or service  (the cost of  which if performed  by Landlord would
constitute an Operating  Cost) to a  tenant who has  undertaken to perform  such
work or  service in lieu of the  performance thereof by Landlord for  all or any
portion  of a fiscal year, Operating Costs for  such fiscal year shall be deemed
to be  increased by  an amount  equal to  the additional  Operating Costs  which
reasonably would have  been incurred during such  fiscal year by Landlord  if it
had,  at  its  own expense,  furnished  such  work or  service  to  such tenant.
Notwithstanding  anything contained  herein to the  contrary, the  provisions of
this paragraph with respect to adjustment  of Operating Costs for vacancy, or as
a result of the performance by tenants of certain services, shall apply only to 
Operating Costs which are variable and which increase as occupancy in the 
Project increases and shall not apply to any  Operating Costs  which do  not 
vary  with the  amount of  occupancy in  the Project.

     (3)  Fiscal Year.  The term  "fiscal year" shall  mean any  12-month period
          -----------
(including, without limitation, the calendar  year) which Landlord may from time
to time select as the fiscal year of the Project, provided that the first fiscal
year and the 

* See page 5a for continuation.













                                       -5-

<PAGE>
last fiscal year of the Term may contain less than twelve (12) months.

     (4)  Tenant's Proportionate  Share.  "Tenant's  Proportionate Share"  shall
          ------------------------------
mean the percentage set forth as Item 7 on the Schedule.

D.   Rules of Interpretation and Computation of Base Rent and Rent Adjustments:
     -------------------------------------------------------------------------

          (1)  If this Lease commences  on other than the first day  of a month,
     the Base Rent, Operating  Cost Share Rent and Tax Share Rent  for the month
     in which this Lease so begins shall  be prorated based upon the number   of
     days  of the  Term falling within  such month.  If the  Term of  this Lease
     commences  on any  day other than  the first  day of the  designated fiscal
     year,  or if the Term of the Lease ends  on any day other than the last day
     of the  designated fiscal year,  any Operating  Cost Share Rent,  Tax Share
     Rent due to the Landlord with respect to such fiscal year shall be prorated
     based on the number of days in the Term falling within such fiscal year.

          (2)  All rent shall  be paid to Landlord without  deduction or offset.
     The Tenant's  covenants to  pay rent  shall be  independent of every  other
     covenant set forth in this Lease.

          (3)  Any sum  due from Tenant to Landlord not  paid when due after the
     applicable  cure period has expired  shall bear interest  from the date due
     after the  applicable cure period  has expired until  the date paid  at the
     annual rate equal to the  lesser of: (i) the highest lawful rate, or (ii) a
     rate of interest equal to the sum of three percent (3%) plus the "Corporate
     Base Rate".  The phrase "Corporate  Base Rate" means that  rate of interest
     most  recently announced  by the  First  National Bank  of Chicago,  or its
     successor  (collectively, the "First") as the corporate base rate, changing
     automatically and simultaneously with each announced change by the First in
     the Corporate Base Rate, such change to  be effective as of and on the date
     announced  by  the  First as  the  effective  date for  the  change  in the
     Corporate Base Rate.  A certificate made by an officer of the First stating
     the Corporate Base Rate in effect on a certain day, or Corporate Base Rates
     in effect during a  certain period, shall, for the purposes  of this Lease,
     be conclusive evidence of the First's Corporate Base Rate or Rates on said
     day or during such period.  In the event that the First ceases to use the
     term Corporate Base Rate in setting a base rate of interest for commercial
     loans, then  the Corporate Base Rate herein shall  be determined by 
     reference to the rate  used by the First as  a base rate of interest for 
     commercial loans as the same shall be designated by the First to the 
     Landlord. The payment of such interest shall not excuse or cure any 
     default of Tenant under this Lease.

          (4)  If Tenant  is in  default of  any of  its obligations  under this
     Lease, Tenant  shall not be  entitled to  any refund of  any sum  which may
     otherwise be due it by application of any provision of this Lease until any
     and all of Tenant's defaults under this Lease are cured by Tenant*.

     (5)  If changes  are made  to this  Lease or  to the  Project changing  the
     number of rentable square feet contained in the Premises or in the Project,
     Tenant's  Proportionate Share  shall  be  appropriately  adjusted  and  the
     computations of rent shall be

                                       -6-


*    , provided, however, that if the amount of  a refund owed to Tenant exceeds
     the amount required to cure all such  Tenant defaults, then Tenant shall be
     entitled to such excess amount.

casualty, or caused by the exercise of the right of eminent domain to the extent
such costs are covered by Landlord's insurance; (i) legal and auditing fees
which are for the benefit of Landlord such as collecting delinquent rents,

otherwise improving, decorating or painting space for tenants or other occupants
or vacant space which is not part of the public areas of the Building; (k)
Landlord's costs of the electricity and other services sold to tenants and for

tenants as an additional charge or rental over and above the base rent  payable
under the lease with such tenant; (1) costs incurred by Landlord in connection
with the enforcement of any other lease in the Building; (m) overhead and profit
increment paid to subsidiaries or affiliates of Landlord for services on or to
the Project, to the extent only that the costs of such services exceed the
competitive costs of such services were they not so rendered by a subsidiary  or
affiliate; (n) Landlord's corporate overhead and general administrative
expenses; (o) any compensation paid to clerks, attendants or other persons in
commercial concessions operated by Landlord, if any; (p) advertising and

paintings, sculptures and other art work over $ 5,000.00 per year, except for 
costs of insuring and maintaining any paintings, sculptures or other art work
owned by Landlord and located in the public areas of the Building; (s) wages, 
salaries or other compensation paid to any executive employees above the grade 
of building manager; (t) costs of correcting defects in construction of the 
Building (as opposed to the cost of normal repair, maintenance and replacement 
expected with the construction materials and equipment installed in the Building
in light of their specifications); (u) repairs and replacements of any equipment
or component of the Project caused by deficient design, selection of materials,
construction or improper maintenance, but only to the extent that such costs are

to timely pay its Proportionate Share of Taxes and Operating Costs.































































<PAGE>
appropriately  adjusted  so as  to  take  into  account the  different  Tenant's
Proportionate Share  figures applicable  during each  portion of the  applicable
fiscal  year. Tenant's  Proportionate Share  is based  upon a  total of  105,924
rentable square  feet in the Building and a total of 19,025 rentable square feet
                                                     ------
in the Premises initially demised hereunder.

     (6)  Landlord shall maintain books and records in accordance with generally
accepted  accounting principles, consistently  applied, as  customarily modified
for income producing  real estate reflecting  the Operating Costs and  Taxes. In
the event of any dispute as to any  Operating Cost Share Rent or Tax Share Rent,
Tenant shall have the right to inspect Landlord's accounting records relative to
Operating Costs and Taxes at  Landlord's accounting office upon reasonable prior
notice during normal  business hours during the  thirty (30) days  following the
furnishing by Landlord to Tenant of either of the Operating Cost Report and  the
Tax Report.  Unless Tenant shall take written exception  to any item in any such
report within said  thirty (30) day period,  such report shall be  considered as
final  and accepted by Tenant. Any  payment due to the  Landlord as shown on the
Operating Cost  Report or the  Tax Report, whether  or not written  exception is
taken  thereto, shall be  made by the  Tenant within twenty  (20) days after the
Landlord shall have  submitted the Operating Cost  Report or the Tax  Report (as
the  case may  be) without prejudice  to any  such written exception.  If Tenant
makes such timely written exception, a certification as to the proper  amount of
Operating  Cost  Share Rent  and  Tax Share  Rent  shall be  made  by Landlord's
independent certified public  accountant (which shall be a  "Big Six" accounting
firm), which shall be final and conclusive. Tenant agrees to pay the cost of 
such certification unless it is determined that Landlord's original 
determination of the aggregate of Taxes and Operating Costs was in error by more
than  five percent (5%) of said amounts.

     (7)  In the  event of the  termination of this  Lease by expiration  of the
stated  Term  or  for  any  other  cause  or  reason  whatsoever  prior  to  the
determination of Operating Cost Share  Rent, Tax Share Rent or Additional  Rent,
Tenant's agreement to  pay any such sum  shall survive termination of  the Lease
and Tenant shall pay any  such amount due to Landlord within fifteen  (15)  days
after being  billed therefor.  Tenant's obligation to  pay Base Rent  shall also
survive  the expiration  or  termination of  this  Lease. In  the  event of  the
termination of this  Lease by expiration  of the stated  Term or for any  other
cause or reason  whatsoever, except the default by Tenant under any of the terms
or provisions of  this Lease, prior to the determination of Operating Cost Share
Rent or Tax Share  Rent as hereinabove set forth, Landlord's agreement to refund
any excess in the amount of the estimated payments made by Tenant on account of
Operating Cost Share Rent or Tax Share Rent over the actual amount thereof 
accruing or payable up to the time of the termination or expiration shall 
survive termination of the Lease and Landlord  shall pay the  amount due  to 
Tenant within  fifteen (15) days  of Landlord's determination of such amount.

     (8)  No calculation, determination or payment of Operating Cost  Share Rent
or Tax Share Rent,  by virtue of the operation of the rent adjustment provisions
under this Section 2  shall result in the payment  by Tenant in any fiscal  year
during the Term of less than the Base Rent shown on the Schedule.

<PAGE>
     (9)  If any Operating Cost though paid in one fiscal year, relates  to more
than one fiscal year, at the option  of the Landlord, such Operating Cost may be
proportionately allocated among such related fiscal years. If any Operating Cost
relates to more than  once parcel of  property, at the  option of the  Landlord,
such  Operating Cost  may  be  proportionately allocated  among  all parcels  of
property to which it relates.

     (10) All payments made  with respect  to Operating Cost  Share Rent or  Tax
Share  Rent (including  any monthly  payments made  on the  basis of  Landlord's
estimates thereof) may be commingled and need not be segregated by  the Landlord
and may be held and  utilized by the Landlord without  payment to the Tenant  of
interest or any sums for the use of any of said amounts.

3.   PREPARATION   AND  CONDITION  OF  PREMISES,  POSSESSION  AND  SURRENDER  OF
PREMISES.

     A.   Except to the  extent expressly indicated  in the Tenant  Improvements
item on  the  Schedule, Landlord  is leasing  the Premises  to  Tenant "as  is",
without  any  representations or  warranties  of  any  kind (including,  without
limitation, any  express or  implied warranties  of merchantability, fitness  or
habitability) and without any obligation  on the part of the Landlord  to alter,
remodel, improve, repair, decorate or clean the Premises or any part thereof. If
so indicated  in the Tenant  Improvements item on  the Schedule, Landlord  shall
cause the Premises to be completed in accordance with the plans, specifications,
and agreements  and on the terms, conditions and  provisions as provided in the
Tenant Improvement  Work Agreement (Appendix D)  and Exhibit A thereto (Building
Standards) both of which are attached hereto and made a part of this Lease.

     B.   During the term of this  Lease, Tenant shall maintain the  Premises in
as good  condition as when  Tenant took possession,  or as  when completed
after  possession  in  the  event that  Tenant  takes  possession  prior  to the
Completion Date  (loss or  damage caused  by  action of  the elements,  Acts of 
God  and the public  enemy, ordinary wear and  fire and other casualty insured 
against  by Landlord excepted), failing which  Landlord may but need not restore
the Premises to such  good condition and Tenant  shall pay the cost thereof.  At
the  termination of  this Lease  or  at the  termination  of Tenant's right  to 
possession  without termination of  the Lease, Tenant shall, subject to Sections
3C and 3D below, return the Premises to Landlord broom clean and  in good  
condition as described  in the immediately  preceding sentence* or Landlord may,
but  need not,  restore the  Premises to such  good condition  and Tenant shall 
pay the cost thereof.

     C.   Unless  otherwise provided by  written agreement, signed  by Landlord,
all Work (hereinafter defined), partitions, hardware, light fixtures,  and other
fixtures (except trade fixtures and movable furniture and equipment belonging to
Tenant) in or  upon the Premises,  whether placed there  by Landlord or  Tenant,
shall  be surrendered  with the Premises  at the  termination of this  Lease, by
lapse of time or otherwise, or at the termination of Tenant's right to 
possession without  termination of this Lease, and shall become Landlord's
property without compensation to Tenant; provided, however, that if prior to any
such termination of the Lease, or of the right to possession, or within ten (10)
days thereafter,  Landlord so directs  by written notice, Tenant  shall promptly
remove any Work,  partitions, hardware, light fixtures or  other fixtures placed
in  or upon the Premises by Tenant and  designated in such notice and repair any
damage to the Premises caused

     public enemy, ordinary wear and fire  and other casualty insured against by
     Landlord excepted)

by such  removal, failing  which Landlord  may remove  the same  and repair  the
Premises and Tenant shall pay the cost thereof to Landlord upon demand.

     D.   Tenant  shall  also  remove its  furniture,  movable  equipment, trade
fixtures and all other items of personal property from the Premises prior to the
end of the Term or  any extension thereof, or within thirty (30)  days after the
early termination  of  this Lease  for  any reason,  or  of the  termination  of
Tenant's right of  possession; and if Tenant  does not remove such  property, at
Landlord's election: (i) Tenant shall  be conclusively presumed to have conveyed
the same to Landlord under this Lease as a bill  of sale without further payment
or credit by Landlord  to Tenant, (ii) Tenant shall be  conclusively presumed to
have  forever abandoned  such  property, and  without  accepting title  thereto,
Landlord may (provided Landlord exercises reasonable care), at Tenant's expense,
remove, store, destroy, discard or otherwise dispose  of all or any part thereof
in any manner that  Landlord shall choose without incurring liability  to Tenant
or  to  any other  person  except  in  the  case of  Landlord's  negligence  and
intentional misconduct, and  Tenant shall pay to Landlord,  upon demand, any and
all reasonable  expenses incurred in  taking any of such  actions.  In  no event
shall Landlord ever become or accept  or be charged with  the duties of a bailee
(either voluntary or  involuntary) of any personal property; and  the failure of
Tenant to  remove all  such property  from the  Premises and  the Project  shall
forever bar  Tenant from bringing any action  or asserting any liability against
Landlord with respect to any such property which Tenant fails to remove.

     E.   All obligations of the Tenant and  the Landlord under this Lease shall
survive the expiration of the Term or sooner termination of this Lease.

     F.   Tenant's  taking possession  of the  Premises  or any  portion thereof
shall be conclusive evidence that the Premises or such portion were then in good
order, repair and satisfactory condition.  Landlord may authorize Tenant to take
possession of all  or any part of  the Premises prior to  the Commencement Date.
If tenant  does  take possession  pursuant  to such  authorization, all  of  the
covenants and  conditions of this  Lease shall apply  to and shall  control such
pre-term occupancy.    Rent  for such  pre-term  occupancy shall  be  paid  upon
occupancy and on the first day of each calendar month thereafter at the rate set
forth in  Section 2A  hereof.   If the  Premises are  occupied for  a fractional
month, such rent shall be prorated on a per diem basis.

     4.   PROJECT SERVICES.

     So long as Tenant is not in default hereunder and such default has not been
cured within the applicable cure period,  Landlord agrees to furnish services to
the Tenant without charge except for Operating Cost  Share Rent, electricity and
as otherwise specifically provided herein, as follows:

     A.   Heat and Air Conditioning.    Landlord  shall  furnish  heat  and  air
          -------------------------
conditioning   to  provide  a  temperature  condition  required,  in  Landlord's
reasonable  judgment, for  comfortable occupancy  of the  Premises under  normal
business operations in the absence of machines or equipment which may affect the
temperature  otherwise  maintained   in  the  Premises.    Such   heat  and  air
conditioning shall  be provided daily during  business hours (8:00  a.m. to 6:00
p.m.  Monday through Friday  and 8:00 a.m.  to 1:00 p.m.  Saturday), Sundays and
Holidays (hereinafter defined) excepted.  Tenant agrees  to keep and cause to be
kept closed all windows in the Premises and at all times to cooperate fully with
the Landlord in the operation of the heating and air conditioning systems and to
abide  by  all  reasonable  regulations  and  requirements  which  Landlord  may
prescribe to permit the proper functioning and protection



                                       -9-

<PAGE>
of  the heating and  air conditioning systems.   Landlord reserves  the right to
stop  the heating  and air  conditioning  systems when  necessary  by reason  of
accident or emergency or for repairs, alterations, replacements or improvements,
which  in the judgment  of the Landlord  are desirable or  necessary, until said
repairs,  alterations, replacements or  improvements shall have  been completed.
For purposes of this Lease "Holidays" shall mean any Legal Holiday as defined in
Ill. Rev. Stat.  1985, Ch. 17, pars. 2201,  2202, as amended from  time to time.
Landlord agrees to make any repairs to the heating  system promptly and with due
diligence.*

     Whenever heavy concentration  of personnel, motors, machines  or equipment,
including  telephone  equipment, used  in  the  Premises adversely  affects  the
temperature  otherwise maintained  by  the  air  conditioning  system,  Landlord
reserves  the right  to  install  supplementary air  conditioning  units in  the
Premises and  the  cost thereof,  including all  of the  costs  relating to  the
installation  and  the cost  of  operation  and  maintenance thereof,  shall  be
Additional Rent hereunder and shall be paid by Tenant to Landlord upon demand.

     Landlord shall also furnish heat and air conditioning after business hours,
on  the condition  that Tenant  gives Landlord  not less  than forty-eight  (48)
hours' prior  notice  of Tenant's  needs  for  such additional  heating  or  air
conditioning, and provided that Tenant pays to Landlord its then current charges
(not to  exceed Landlord's  actual costs)  for  such additional  heating or  air
conditioning.   Such  charges will  be prorated  by Landlord  between requesting
user-tenants if  more than one  tenant requests  such additional heating  or air
conditioning at the same  time and the proration shall  be based on the area  of
the Project leased to such tenants and their respective periods of use.

     B.   Elevators.     Landlord shall  provide passenger  elevator service  in
          ---------
common with the Landlord  and the other tenants,  daily, during business  hours,
Sundays and Holidays  excepted.  Tenant may request  additional freight elevator
service provided that such  service shall be at Tenant's sole  cost and expense.
Elevator service for  other than passenger service shall at all times be subject
to  reasonable  scheduling by  the  Landlord.   Notwithstanding  the  foregoing,
Landlord shall provide limited passenger elevator service at all times including
Sundays, (except  in the  case of  an emergency)  during which  normal passenger
elevator service is not furnished.

     C.   Electricity.   All  the  electricity  used in  the  Premises  shall be
          -----------
supplied by Commonwealth Edison Company or any other electricity company serving
the Project, and such electricity shall be supplied through a separate meter and
be  paid for  by Tenant, provided  that Landlord  shall pay for  the electricity
required for the operation of the Building's shared heating, ventilating and air
conditioning systems at  the times  specified in  Section 4A above.   The  meter
shall  be  installed  at the  expense  of  Tenant  or the  electricity  company.
Landlord shall  not in any  way be liable  to Tenant for  any loss or  damage or
expense Tenant may sustain or incur if either the  amount or quality of electric
service  is  changed  or  is  no  longer  available  or  suitable  for  Tenant's
requirements.  If such service  shall be discontinued, such discontinuance shall
not  in any way affect this Lease.   Tenant covenants and agrees that its use of
electric current shall  never exceed the capacity of the existing feeders to the
Building or  the  risers  or  the  wiring installed  thereon  when  reviewed  in
conjunction  with the  electrical usage  of the  other tenants  in the  Project.
Tenant shall make no alterations  or additions to the electric equipment  and/or
appliances  without the  prior written  consent  of Landlord  in each  instance.
Landlord shall maintain the light fixtures

Landlord shall furnish air conditioning such that the average temperature
condition of the Premises is 75 F +/- 2 F dry bulb with 50% +/- 5% relative 
humidity when the outdoor conditions are not above 90 F dry bulb, and Landlord 
shall furnish heat such that the average temperature condition of the Premises 
is 68 +/- 2 F dry bulb when the outdoor conditions are not below 5 F dry bulb. 
The above temperatures are based on an occupancy density of not more than one 
(1) person per one hundred (100) square feet of usable area and an average
electrical load of eight (8) watts per rentable square foot.

in the Premises and install any lamps, bulbs, ballasts or starters to be used by
Tenant in the Premises, all at Tenant's sole cost and expense.*

     Tenant shall pay for all electricity required during janitorial service and
alterations and repairs to the Premises and Tenant shall pay for all electricity
required for the operation of any special air conditioning or ventilating system
for its office machinery or equipment requiring special or extra current.

     D.   Water.    Landlord  shall furnish cold  water from City  of Northbrook
          -----
mains from regular Building outlets  for drinking, lavatory and toilet purposes,
drawn through fixtures installed by Landlord or by Tenant with  Landlord's prior
written consent,  and hot water  for public lavatory  purposes from the  regular
supply of the Building.   Tenant shall pay  Landlord at rates fixed  by Landlord
(not  to exceed  Landlord's  actual costs)  for water  furnished  for any  other
purpose  as Additional  Rent hereunder.   Tenant shall  not waste or  permit the
waste of water.

     E.   Janitorial Service. Landlord   shall  also   furnish  janitorial   and
          ------------------
cleaning services as set forth in Appendix B, on Monday through Friday, Holidays
excepted.  Tenant shall not provide  janitorial services in the Premises without
the  prior  written  consent  of  Landlord  and  then   only  at  Tenant's  sole
responsibility,  cost and  expense, by  contractors  or employees  at all  times
satisfactory to Landlord in its sole discretion.

     F.   Window Washing.     Landlord  shall  furnish  window  washing  of  all
          --------------
exterior windows, weather permitting, at intervals to be determined by Landlord,
but not less than three times during each calendar year.

     G.   Interruption of Service. Landlord does  not warrant  that any  service
          -----------------------
will  be  free  from  interruption caused  by  labor  controversies,  accidents,
inability to obtain fuel, steam, water or supplies, governmental regulations, or
other  causes  beyond  the  reasonable  control of  the  Landlord,  or  repairs,
alterations, replacements or improvements to such systems.  No such interruption
of  service shall  be deemed  an  eviction or  disturbance of  Tenant's  use and
possession of the  Premises or any  part thereof, or  render Landlord liable  to
Tenant for damages,  by abatement of rent  or otherwise, or relieve  Tenant from
performance of Tenant's obligations under this Lease.**

     Tenant   shall  make  arrangements  directly  with  the  telephone  company
servicing the  Building for  such telephone service  in the  Premises as  may be
desired by  Tenant.  Tenant shall pay the  entire cost of all telephone charges,
electricity consumed  within the  Premises, maintenance  of  light fixtures  and
replacement of lamps, bulbs, tubes, ballasts and starters.

     5.   ALTERATIONS AND REPAIRS.

     A.   Tenant shall not make any improvements or alterations in or additions,
changes  or installations  to the  Premises (collectively,  the "Work")  without
submitting plans  and specifications therefor  to Landlord, and in  the cause of
such  work  affecting the  structure  or  mechanical  systems of  the  Building,
obtaining  Landlord's prior  written consent  in  each instance.   Landlord  may
withhold such consent in its  sole discretion.  All Work shall  be performed (a)
at the sole  cost and expense of Tenant by employees  of or contractors employed
by Landlord, or, provided Tenant's use  of labor does not create any  disharmony
with trades  in the Building, by contractors employed  by Tenant under a written
contract previously



                                      -11-

*    Landlord represents that  the Building is capable of supplying  8 watts per

CONTINUATION OF SECTION 4G.
- --------------------------

     Notwithstanding anything to the contrary contained in this Section 4G, if
(i) Landlord ceases to furnish any service in the Building as a result of a
condition which affects only the Building (and does not affect office buildings
in general in the north suburban Chicago area), and Tenant notifies Landlord in
writing within one (1) business day after such cessation, (ii) such cessation is
within Landlord's reasonable control (that is, is not caused by Force Majeure
[hereinafter defined], (iii) such cessation does not arise as a result of an act
or omission of Tenant, and (iv) as a result of such cessation the Premises or a
material portion thereof, is rendered untenantable (meaning that Tenant is
unable to use such space in the normal course of its business) and Tenant in
fact so ceases to use such space, or material portion thereof, in the manner
used prior to such cessation, then, Tenant's remedy for such cessation shall be
as follows:  on the third business day after the affected space becomes
untenantable, Tenant ceases to use such space, and Tenant so notifies Landlord
in writing thereof, the rent payable hereunder shall be equitably abated based
upon the percentage of the space in the Premises so rendered untenantable and
not being so used by Tenant, and such abatement shall continue until the date
the Premises become tenantable again.












































<PAGE>
approved in writing by Landlord, and (b) on such terms and under such conditions
as  Landlord,  in its  sole  discretion,  shall determine  as  will protect  the
Premises,  the Building  and the  Project  from improper  contractors' work  and
against the imposition  of any lien  resulting from  Work; without limiting  the
foregoing, if Landlord  consents to any Work,  it shall be performed  subject to
the following requirements:

          (1)  If  the Work is to be done  by Tenant's contractors, Tenant shall
     furnish to  Landlord prior to  commencement thereof,  building permits  and
     certificates  of  appropriate  insurance  and  bonds  satisfactory  in  all
     respects to  Landlord.  Tenant shall also  furnish to Landlord, if Landlord
     so requests,  security  for the  payment of  all costs  to  be incurred  in
     connection with the Work.

          (2)  Upon completion of any  Work, Tenant shall furnish Landlord  with
     contractors' affidavits and full and final waivers of lien, each conforming
     to the applicable  Illinois statutory requirements,  as-built plans of  any
     Work  and receipted  bills covering  all labor  and materials  expended and
     used.   Insofar as applicable to the work or  material for which payment is
     requested or notice or lien claim is made, Landlord in its sole discretion
     shall make available for partial  or final payment or release thereof  such
     funds as may have  been deposited with it by Tenant for  the estimated cost
     of such Work.

          (3)  Any Work permitted to be undertaken by Tenant's contractors shall
     be performed in such a fashion and by such means as necessarily to maintain
     peace  and harmony among the other  contractors serving the Project and the
     other tenants  and so as not to cause  interference with the continuance of
     work to be performed or services to be rendered to the Project or the other
     tenants.

          (4)  All Work shall  comply with all  insurance requirements and  with
     all  applicable  laws, ordinances  and  regulations.    All Work  shall  be
     constructed in  a good  and workmanlike  manner,  and only  good grades  of
     material shall be used with a quality equal to or better than  that used in
     the Project.

          (5)  Tenant shall  permit Landlord  to supervise  all Work within  the
     Premises.   Landlord  shall charge  a  supervisory fee  not  to exceed  (a)
     fifteen  percent (15%)  of the total  cost of the  Work, including, without
     limitation,  all labor  and  material  costs,  if Landlord's  employees  or
     contractors perform the Work, and (b)  ten percent (10%) of the total  cost
     of the Work,  including, without limitation, all labor  and material costs,
     if Tenant's employees or contractors perform the Work.

     B.   If  Tenant desires  telegraphic, telephonic,  burglar alarm,  computer
installations or signal service (all of which shall be at Tenant's sole cost and
expense), Landlord shall, upon request, direct where and how all connections and
wiring for such service shall be introduced and run.  In the absence of any such
directions, Tenant shall make no borings, cutting  or install any wires or cable
in or about the Premises.

     C.   Tenant agrees to  protect, defend and  indemnify Landlord, its  agents
(including,  without  limitation,  the  building  manager)  and  employees,  the
Premises, the Building and the Project from and against any and  all liabilities
of every kind  and description (except for Landlord's  negligence or intentional
misconduct) which may arise








                                      -12-

<PAGE>
out of or be  connected in any way with any Work, whether  performed by or under
the direction of Landlord  and at the cost of Tenant or  performed by Tenant and
whether performed in compliance with this Section 5.

     D.   Any  mechanic's lien filed against the  Premises or the Project or any
notice which  is received  by either Landlord  or Tenant  or filed  for work  or
materials  furnished or claimed  to be furnished  and deriving from  Work or for
materials or work claimed to have been furnished to Tenant or the Premises shall
be released and  discharged of record by  Tenant, in either case,  within thirty
(30)  days after such  filing or  receipt, whichever  is applicable, at Tenant's
expense.  If Tenant chooses to contest such claim, notice or lien, Tenant may do
so in place of causing the  release and discharge thereof, provided that  within
said thirty (30) day period: (i) Tenant provides Landlord with a title indemnity
or bond or other adequate security covering any possible lien or claim that  may
arise from the failure to release and discharge such claim, notice or lien; (ii)
Tenant contests  such  claim,  notice  or lien  in  good  faith  by  appropriate
proceedings that operate to stay  enforcement thereof; and (iii) Tenant promptly
pays and discharges any final  adverse judgment entered in any  such proceeding.
If Tenant  has  not caused  the  release  or  discharge  or  begun  appropriate
proceedings to contest such claim, notice or lien, within said thirty (30) days,
Landlord may, but shall not be obligated to, pay  the amount necessary to remove
the  same  without being  responsible  for making  an  investigation  as to  the
validity or accuracy  thereof, and the amount  so paid, together with  all costs
and  expenses  (including,  without  limitation,  reasonable  attorneys'   fees)
incurred by  Landlord in connection  therewith, shall be deemed  Additional Rent
hereunder, payable upon demand.   Tenant has no  power or authority to  cause or
permit any lien or encumbrance of any kind whatsoever, whether created by act of
Tenant, operation of law or otherwise, to attach to or be placed upon Landlord's
title or  interest in the  Premises or the  Project, and any  and all liens  and
encumbrances created by Tenant shall attach to Tenant's interest only.

     E.   Except  for ordinary  wear and  as otherwise  provided in  this Lease,
Tenant shall, at all times during the Term hereof, at its sole expense, keep all
Tenant's  movable  and removable  fixtures  located  in  or appurtenant  to  the
Premises in good  order, repair and condition, and Tenant shall promptly arrange
with the Landlord to have Landlord or Landlord's agent make repairs of all other
damages to  the Premises and the replacement or repair of all  damaged or broken
glass (including signs thereon),  fixtures and appurtenances (including hardware
and heating,  cooling, ventilating,  electrical, plumbing  and other  mechanical
facilities in the  Premises), with materials equal  in quality and class  to the
original  materials damaged  or broken,  within  any reasonable  period of  time
specified by Landlord.   Upon reasonable advance oral notice,  Landlord may, but
shall not  be required to do so, enter the Premises during normal business hours
(except  in the case  of  an  emergency)  to  make  any  repairs,  alterations,
improvements  or additions, as Landlord  shall desire or  deem necessary for the
safety, protection, preservation  or improvement of the Project,  or as Landlord
may be required to  do by any governmental department or agency, or by the order
or decree  of any  court or  by any  other proper authority.   The  cost of  all
repairs  made by  Landlord  to the  Premises (except  those necessitated  by the
negligence or  intentional misconduct of Landlord or  its employees, contractors
or agents) shall  be immediately paid as  Additional Rent by Tenant  to Landlord
upon being billed for same.  Similarly, the cost of all repairs made by Landlord
to the Project (other than the Premises) which are made necessary as a result of
misuse  or  neglect  by  Tenant  or  Tenant's  employees,   invitees,  servants,
contractors or agents shall be immediately paid as Additional Rent by  Tenant to
Landlord upon being billed for the same.









                                      -13-

<PAGE>
The cost of all other repairs and replacements (except those caused  by Tenant's
misuse  or negligence  and  those  relating to  Tenant's  movable and  removable
fixtures) shall  be paid for  by the  Landlord and deemed  an item of  Operating
Costs.

     6.   USES OF PREMISES.   The  Premises shall be occupied and used by Tenant
only for general  office purposes, and for  no other purpose.   Without limiting
the generality of the foregoing, no  use shall be made of the Premises  nor acts
done  which will  increase the existing  rate of  insurance upon the  Project or
cause  cancellation of any  insurance policy  covering the  Project or  any part
thereof or require additional insurance coverage.  Tenant shall not permit to be
kept, used or sold  in or about the Premises any article which may be prohibited
by Landlord's insurance policies.

     7.   BUILDING RULES AND GOVERNMENTAL REGULATIONS. Tenant shall abide by all
applicable laws or governmental regulations  concerning its use of the Premises.
Tenant shall also abide by all uniform reasonable rules and regulations  adopted
or to be adopted  from time to time by Landlord pertaining  to the operation and
management  of the Project.   If any  rules and regulations  are contrary to the
terms of the Lease,  the terms of this  Lease shall prevail.  The  present rules
are contained  in Appendix C.  The violation of the Project rules or the laws or
regulations governing Tenant's use of the Premises shall be a default under this
Lease allowing Landlord all  remedies for default set forth under  Section 11 of
this Lease.*  Landlord shall not be responsible to Tenant for violation of rules
or regulations  or terms  of this  Lease or any  other lease  in the  Project by
another  tenant,  nor shall  failure  to obey  the  same  by others  or  lack of
enforcement by Landlord relieve Tenant from its obligations to comply therewith.

     8.   CLAIMS; INSURANCE; LIABILITY.

     A.   To the  extent permitted by law, Tenant waives  all claims it may have
against Landlord,  its officers, directors,  servants, agents  or  employees for
damage  to person  or property  sustained by  Tenant or  by any occupant  of the
Premises or the Project, or any other person, occurring in or about the Premises
or the  Project, resulting from the Premises or the  Project or any part of said
Premises or  Project becoming out  of repair or  resulting from any  existing or
future condition, defect,  matter or thing in  the Premises, the Project  or any
existing or future part of it, or from equipment  or appurtenances therein, or 
from the action  of the elements, or any accident  within or adjacent to the 
Premises  or Project or resulting  directly or indirectly  from any act  or 
omission of  Landlord or any occupant of the Premises or  Project or any other 
person while on the Premises or the Project.  If any such damage to the Premises
or the Project or any equipment or appurtenances  therein, or  to tenants 
thereof,  or their  agents, employees, contractors or invitees, results from any
act, omission or negligence of Tenant, its  agents, employees,  servants,  
contractors or  invitees,  Landlord may,  at Landlord's option, after  giving 
Tenant notice and an opportunity to cure during the applicable cure period, 
except in the event (i) of an emergency or (ii) that to  wait  for such  period
before  repairing such  damages would  cause further detriment to  Landlord or 
any other tenant, repair  such damage and Tenant shall upon demand by  Landlord
reimburse Landlord  for all costs  of such repairs  and damages.   All  property
on  the Project  or in  the  Premises belonging  to the Tenant,  its  agents, 
employees,  servants,  contractors or invitees or  to  any occupant of the 
Premises shall be there at the risk of the  Tenant or such other person only  
and Landlord shall not be liable for damage thereto or theft, misappropriation
or loss thereof.   Notwithstanding anything  contained in this Section 8 to the
contrary, no agreement of Tenant in this Section 8 shall be deemed to exempt 
Landlord  from liability for injury  to persons or damage  to property caused 
by or resulting from the negligence or intentional misconduct of Landlord or its
employees, contractors or agents, its agents or

                                      -14-

*    Landlord agrees that such rules and regulations will apply to all  tenants,
     and  Landlord  shall use  reasonable  efforts  to  enforce such  rules  and
     regulations, provided that



<PAGE>
employees in the operation or maintenance of the Premises or the Project.

     B.   Landlord  and Tenant  agree to  have all  property insurance  policies
which may be carried by either of them endorsed with a clause providing that any
release from liability of  or waiver of claim for recovery  from the other party
entered into in  writing by the insured thereunder  prior to any loss  or damage
shall  not affect the  validity of said  policy or the  right of  the insured to
recover thereunder.   Without  limiting any  release or  waiver of liability  or
recovery contained in any other section of this Lease but rather in confirmation
and  furtherance thereof, Landlord  and Tenant each  hereby waive  any and every
claim  for recovery  from the other  for any  and all loss  of or  damage to the
Project or the  Premises or to  the contents  thereof, which loss  or damage  is
covered by valid and collectible  fire and extended coverage insurance policies,
to the  extent that  such loss  or damage  is recoverable  under said  insurance
policies.  Inasmuch  as this mutual waiver  will preclude the assignment  of any
such claim  by subrogation (or otherwise) to an  insurance company (or any other
person), Landlord and Tenant each agree to  give to each insurance company which
has  issued, or  in the  future may  issue, its  policies of  fire and  extended
coverage insurance, written  notice of the terms  of this mutual waiver,  and to
have  said insurance  policies properly  endorsed, if  necessary to  prevent the
invalidation of said insurance coverage by reason of said waiver.

     C.   At all times during  the Term of this Lease, Tenant  shall at its sole
cost and expense maintain in full  force and effect insurance protecting  Tenant
and Landlord  and their respective agents  and employees, and any  other parties
designated by Landlord from time to time, with terms, coverages and in companies
at all times satisfactory to Landlord  and with such increases in limits as  
Landlord may, from  time to  time, request.   Initially,  such coverage  shall 
be in  the following amounts:

          (1)  Comprehensive   or   Commercial  General   Liability   Insurance,
     including  Contractual  Liability insuring  the  indemnification provisions
     contained in this Lease, with limits  of not less than One Million  Dollars
     ($1,000,000.00) combined  single limit  per occurrence  for Bodily  Injury,
     Death and  Property Damage,  and umbrella coverage  of not less  than Three
     Million Dollars ($3,000,000.00).   The Comprehensive or  Commercial General
     Liability policy shall include the Landlord and Landlord's building manager
     as additional insureds, with a severability of interest endorsement.

          (2)  Insurance against (a) "All Risks"  of physical loss covering  the
     tenant improvements  (if any)  described in  Item 12  of the Schedule,  the
     Work,  movable  fixtures,  office  equipment,  furniture,  trade  fixtures,
     merchandise and all other items  of Tenant's property on the Premises,  and
     (b) loss of use of the Premises.

     D.   Tenant hereby agrees  to, prior to the commencement of the Term hereof
and  prior  to the  expiration  of  any  policy, furnish  Landlord  certificates
evidencing  that  all required  insurance is  in force  and providing  that such
insurance  may not be  cancelled or changed  without at least  thirty (30) days'
prior written notice to Landlord and Tenant  (unless such cancellation is due to
nonpayment of premiums,  in which event ten (10) days' prior written notice 
shall be provided).

     E.   Tenant hereby agrees  to indemnify, defend and hold  harmless Landlord
and its officers,  directors, servants, agents and employees  against any claims
or liability for damage to person  or property (or for loss or  misappropriation
of  property) occurring in the Premises or Project arising from  any  breach or
default  on the part of Tenant during the Term  of this Lease or from any act or
omission of Tenant  or of any employee, agent, servant, invitee or contractor of
Tenant,  and from  any costs  relating thereto  (including, without  limitation,
attorneys' fees).
     *
     9.   FIRE AND OTHER CASUALTY.

     A.   In the event that (i) the Premises are made substantially untenantable
by fire  or other casualty, including damage or  casualties of war, and Landlord
shall decide  not to  restore or repair  the same,  or (ii)  the Building is  so
damaged by fire or other  casualty that Landlord shall decide to demolish or not
rebuild the  same, then,  in either of  such events,  either Landlord  or Tenant
shall  have the  right to  terminate this  Lease by notice  to the  other within
ninety (90) days after the date of such fire or other casualty.

     B.   If the Premises or the Building are made untenantable by fire or other
casualty, and  this  Lease is  not  terminated  pursuant to  Section  9A  above,
Landlord shall,  to the extent permitted by any  mortgages or Ground Leases with
respect to the  Premises and  the Project,  immediately take such  action as  is
necessary to make applicable insurance proceeds available and to use the same to
reconstruct, repair and restore the Building and the Premises, subject to zoning
laws and building  codes then in  effect, and  including only Building  Standard
Tenant Improvements (as provided in Exhibit A of Appendix D) or, if any  portion
of the Premises has been leased on an "as is" basis, including only improvements
similar to those  located in such  portion of the  Premises on the  Commencement
Date or  the date on which such portion was added to the Premises, if later than
the Commencement Date (herein, the improvements Landlord is required to make are
called  the "Required  Improvements"), and  at Landlord's  option Tenant  may be
permitted or  required to  devote  the proceeds  of its  insurance described  in
Section  8C(2)(a) to cause restoration of tenant improvements over and above the
Required Improvements, and pay  for the same to Landlord or  through Landlord as
if newly done pursuant to Section 5 of this Lease.  In the event a fire or other
casualty occurs and both Landlord and Tenant are insured, it is  agreed that the
coverage of the  Landlord shall be  primary and that  Landlord's recovery in  no
event shall be reduced by any insurance recovery to Tenant.

     C.   Notwithstanding  anything in  this Section 9  to the  contrary (except
that in the event of an  inconsistency, Section 9A shall supersede this  Section
9C), if all or any portion of the  Premises shall be made untenantable by a fire
or other casualty, Landlord shall with reasonable promptness, cause a registered
architect  selected by  Landlord  and licensed  to  do business  in  Illinois to
estimate  the amount  of  time  required to  substantially  complete repair  and
restoration  of the  Premises  and  make the  Premises  tenantable again,  using
standard working methods.  If the estimate indicates that the Premises cannot be
made tenantable within nine (9) months from the date the repair  and restoration
is started, either party shall have the right to terminate this  Lease by giving
to the other notice  of such election within ten (10) days  after its receipt of
the  architect's certificate.    If  the estimate  of  the registered  architect
indicates that the Premises  can be made tenantable within nine  (9) months from
the date the repair and restoration  is started, or if neither party  terminates
this Lease  pursuant to this Section 9C,  Landlord shall proceed with reasonable
promptness to repair

CONTINUATION OF SECTION 8E.
- --------------------------

Landlord hereby agrees to indemnify, defend and hold harmless Tenant and its
officers, directors, servants, agents and employees against any claims or
liability for injury to person, including death, or damage to property (or for
loss or misappropriation of property occurring in the Premises or the Building),
proximately caused by the intentional misconduct or sole negligence of Landlord
or of any employee, agent, servant, invitee or contractor of Landlord, and from
any costs relating thereto (including, without limitation, attorneys' fees);
provided, however, that such indemnification shall be effective only to the
extent of the sum of (i) amounts of Landlord's deductibles under the insurance
policy obtained by Landlord, and (ii) amounts of insurance proceeds recoverable
and recovered under such insurance policy.

                                      -36H-

    On January 1, 1995 (the "Third Availability Date"), Tenant shall have the 
                             -----------------------
right to expand into 5,376 rentable square feet (the "Third Expansion Space") on
                                                      ---------------------
the fourth floor of the Building.

     The initial Base Rent for the Expansion Space shall be at Market Rate
(defined in Section 28A).

     B.   Tenant's options to expand shall be exercised as follows:  Tenant
shall deliver an initial non-binding written notice to Landlord of its intent to
exercise its option to expand not less than six (6) full calendar months prior
to the First or Second Availability Date, and not less than twelve (12) full
calendar months prior to the Third Availability Date.  Tenant shall give final
binding written notice of its intent to exercise its option to expand no later
than five (5) full calendar months prior to the First or Second Availability 
Date, and no later than nine (9) full calendar months prior to the Third 
Availability Date.  If Tenant fails to give its initial non-binding written 
notice or its final binding written notice of intent to exercise its option to 
expand when due as hereinabove provided, Tenant will be deemed to have waived 
such option to expand.  Promptly after Tenant's exercise of its expansion
option pursuant to this Section 34, Landlord shall prepare an amendment to the
Lease to reflect changes in the size of the Premises, Base Rent, Tenant's
Proportionate Share and any other appropriate terms, due to the addition of the
Expansion Space.  Tenant shall execute and return such an amendment to the Lease
within fifteen (15) days after its submission to Tenant.

     C.   Tenant's right to exercise its option to expand pursuant to this
Section 34, is subject to the condition that on the date that Tenant delivers
its final binding written notice of its election to exercise its option to
expand, Tenant is not in default under any of the terms, covenants or conditions
of this Lease after having been given notice and an opportunity to cure within
the applicable cure period.

and  restore the  Premises,  provided that  if  the estimate  of  the registered
architect indicates  that the  Premises can be  made tenantable within  nine (9)
months from the date repair and restoration is started, and if Landlord does not
repair and restore  the Premises within two  (2) months after the  expiration of
said nine (9) month period, which nine (9) month period shall be extended to the
extent of any  Reconstruction Delays, then Tenant may  terminate this Lease upon
fifteen (15) days prior written notice to Landlord.  For purposes of this Lease,
the term  "Reconstruction Delays"  shall mean:   (i)  any delays  caused by  the
insurance adjustment  process; (ii) any delays  caused by Tenant; and  (iii) any
delays caused by events beyond Landlord's reasonable control.

     D.   In the event that this Lease  is terminated pursuant to Section 9A  or
Section 9C above, rent  shall be apportioned on a per diem basis  and be paid to
the date of the fire or other casualty.  In the event that such fire or casualty
renders  all or any portion  of the Premises untenantable  and this Lease is not
terminated  pursuant to  Section 9A  or  Section 9C,  then subject  to  the last
sentence of this Section 9D, the rent provided for in  this Lease shall abate on
a per diem basis during the period  of repair and restoration until the Premises
are tenantable  again, and the abatement shall be in  an amount bearing the same
ratio to  the total  amount of  rent due  for such  period  as the  untenantable
portion of  the Premises from time to time bears  to the entire Premises**.  Any
provision hereof notwithstanding, Tenant' rent shall not abate if its negligence
was the cause  of the fire  or other casualty; and  whether or not the  Lease is
terminated, Tenant's recovery  shall be limited to the amount necessary to cause
restoration of the tenant improvements as described in this Section 9.

     10.  RIGHTS  RESERVED TO  THE  LANDLORD.   Landlord reserves  the following
rights, exercisable  without  notice to  Tenant  except as  otherwise  expressly
provided  herein, and  without  liability  to Tenant  for  damage or  injury  to
property,  person or business (all such claims  being hereby released, except to
the  extent they  are caused  by Landlord's  negligence), and  without effecting
an eviction or disturbance  of Tenant's  use or possession or giving rise to any
claim  for  offsets,  or  abatements  of  rent  or  affecting  any  of  Tenant's
obligations  under this Lease.  Specification of the rights reserved to Landlord
herein shall not exclude  any right accruing to Landlord by operation  of law or

to be installed  in the Premises  by Tenant without  Landlord's approval of  the
sign  and  the  location thereof,  which  may  be  withheld in  Landlord's  sole
discretion.  Landlord reserves the right to remove at Tenant's expense  any such
sign not so approved by Landlord.

     C.   Windows:  To designate and  approve, prior to installation,  all types

,  provided,  however,  that if  at  least  20%  of  the  Premises  is  rendered
untenantable and  as a  consequence thereof Tenant  is not  able to  operate its
business, then Tenant  shall be  entitled to  total abatement of  Rent for  such
period of inoperation of Tenant's business.

supplies,  beverages,  food service,  shoe  shining  or  other services  on  the
Premises,  provided  that the  rates  for  such services  as  are designated  by

otherwise, in  and about the  Premises, the Project  or any part  thereof as set
forth in various sections of this Lease including, without limitation, Section 5
and Section 10N.*

     G.   Occupancy:   To decorate, remodel, repair,  alter or otherwise prepare
          ---------
the Premises for  reoccupancy at any time  after Tenant vacates or  abandons the
Premises.   Such acts of Landlord shall  not relieve Tenant of its obligation to
pay rent to the Termination Date.

     H.   Rights to Conduct Businesses: To grant to  anyone the exclusive  right
          ----------------------------
to conduct  any business  or render  any service  in the  Project provided  such
exclusive right shall  not operate to exclude  Tenant from the use  permitted by
this Lease.

     I.   Heavy Equipment:  To approve the weight, size or location of safes and
          ---------------
other heavy equipment and articles in and about the Premises and the Project and
to require all such items and furniture to be moved into and out of the Building
or anywhere else in the Project and the  Premises only at such times and in such
manner as Landlord shall direct in writing.   Movement of Tenant's property into
or out  of the  Project  and within  the Project  is entirely  at  the risk  and
responsibility  of  Tenant.   Any  furniture,  equipment, curtains  and  similar
articles desired to be removed from the Premises or the Building shall be listed
in a written notice from Tenant to  Landlord and a removal permit therefor shall
be obtained from Landlord prior to removal thereof.

     J.   Show Premises:  To show the Premises to prospective tenants or brokers

and occupancy of the Premises shall not materially be inconvenienced by any such
action of Landlord.

     K.   Close Project:  To close or restrict access to the Project during such
          -------------
hours as Landlord shall from time to  time reasonably determine, and on Holidays
subject,  however,  to Tenant's  right  to  admittance at  all times  under such
regulations as Landlord  may prescribe from time  to time which may  include, by
way of  example but  not of  limitation, that  persons entering  or leaving  the
Project identify themselves to a security guard by registration or otherwise and
that said persons establish their right to enter or leave the Project.


                                      -18-


*    Landlord  shall exercise its  right of access during  normal hours and upon
     reasonable advance oral notice, except (i) in the case of an  emergency and
     (ii) in connection with providing janitorial services.



<PAGE>
     M.   Use of  Lock Box by Landlord:  Landlord may from time to time elect to
          ----------------------------
designate  a  lock  box  collection  agent (independent  agent,  bank  or  other
financial institution) to act as Landlord's  agent for the collection of amounts
due Landlord.   In such  event the date  of payment of  rent or other  sums paid
Landlord through such agent shall be the date of agent's receipt of such payment
(or the date of collection of  any such sum if payment is made in the  form of a
negotiable  instrument  thereafter  dishonored upon  presentment);  however, for
purposes of this Lease, no such payment or collection shall be deemed "accepted"
by Landlord if Landlord issues a check payable to the order of the Tenant in the
amount sent  to the  lock box  and if  Landlord mails  the check  to the  Tenant
addressed to the  place designated  in this  Lease for notice  to Tenant  within
twenty-one (21) days after the amount sent by the Tenant is received by the lock
box collection agent or if the  Landlord returns a dishonored instrument  within
twenty-one (21)  days of its dishonor.   Return of any such sum  to Tenant by so
sending such a check of the Landlord or by so sending a dishonored instrument to
the Tenant within the appropriate twenty-one (21) day period shall be  deemed to
be rejection of Tenant's tender of such payment for all  purposes as of the date
of  Landlord's  lock  box  collection   agent's  receipt  of  such  payment  (or
collection).   The return  of Tenant's payment  in the manner  described in this
Section 10M shall be deemed  not to be a waiver of  any breach by Tenant of  any
term,  covenant or condition  of this  Lease nor a  waiver of any  of Landlord's
rights or remedies granted  in this Lease.  The possession of  Tenant's funds or
negotiation of Tenant's  negotiable instrument by  Landlord's agent or  Landlord
during the applicable  twenty-one (21) day  period shall be  deemed not to be  a
waiver of  any defaults of Tenant or any  rights of Landlord theretofore accrued
nor shall any  such possession  or negotiation  be considered  an acceptance  of
Tenant's tender.

     N.   Repairs and  Alterations:   At any time,  Landlord may  decorate, make
          ------------------------
alterations, additions  or improvements, structural  or otherwise, in or  to the
Project  or any  part  thereof, including  the Premises,  and  perform any  acts
required  or  permitted  hereunder,  or  related  to  the  safety,   protection,
preservation  or improvement  of the Project  or the  Premises, and  during such
operations Landlord shall have































                                      -19-

<PAGE>
the right to take  into and through the Premises or any part  of the Project all
material and equipment  required and to close and  temporarily suspend operation
of  entrances, doors,  corridors, elevators  and other  facilities, and  to have
access  to and  open all  ceilings,  without liability  to Tenant  by  reason of
interference, inconvenience, annoyance  or loss of business;  provided, however,
that Landlord shall cause as little  inconvenience or annoyance to Tenant as  is
reasonably possible  under the circumstances, shall  not do any  act which would
permanently reduce the size of the  Premises*.  Landlord shall do any  such work
during ordinary business  hours, and Tenant shall pay Landlord  for overtime and
for any  other expenses  incurred if  such work  is done  during other  hours at
Tenant's request.  Landlord may do or permit any work to be  done upon or along,
and any use of, any adjacent or nearby building, land, street, alley or way.

     O.   Mail Chutes:  To  have access for Landlord and other  occupants of the
          -----------
Building to  any mail chutes according to the  rules of the United States Postal
Service.

     P.   Other Rights:  All other  rights reserved by the Landlord  pursuant to
          ------------
the provisions of this Lease.

          --------
default hereunder:

          (1)  If Tenant  defaults in  the payment of  rent (whether  Base Rent,
     Operating Cost Share Rent, Tax Share Rent or Additional Rent), or any other
     sum  required to be  paid by this  Lease; provided, however,  that Landlord
     shall not be entitled to exercise its  remedies set forth herein or at  law
     or in  equity with  respect to  such default,  unless such  default is  not
     remedied  within five  (5) business  days after  written notice  thereof by
     Landlord to Tenant;

          (2)  If  Tenant  defaults  in  the  prompt  and  full  performance  or

     (except those  specified in Subsections (1),  (3), (4), (5), (6),  (7), (8)
     and (9) of this Section 11A); provided, however, that Landlord shall not be
     entitled to exercise its remedies set  forth herein or at law or in  equity
     with respect to such default, (i) if such default is remedied within thirty
     (30) days after written notice thereof by the Landlord, (or if such default
     involves a hazardous condition  and it is not  cured by Tenant  immediately
     upon written  notice to Tenant),  or (ii) with  respect to a  default which
     cannot reasonably be  cured within thirty (30) days,  if Tenant immediately
     commences  to cure  and diligently proceeds  to complete  the cure  of such
     default  within a  reasonable time  period which shall  in no  event extend
     beyond  ninety (90)  days  after  Tenant receives  written  notice of  such
     default;

          (3)  If  Tenant  abandons  or  vacates the  Premises  during  the Term
     hereof;

          (4)  If  the  leasehold  interest  of  Tenant  is  levied  upon  under
     execution or  is attached under  process of  law, which levy  or attachment
     continues for a period of thirty (30) days;


                                      -20-


*     ,  and  shall not  unreasonably  interfere with  Tenant's  normal business
     operations, except in the case of an emergency.






<PAGE>
          (5)  If  Tenant becomes insolvent  or bankrupt or  shall generally not
     pay its debts as they become due or shall admit in writing its inability to
     pay  its debts  or  shall make  a  general assignment  for  the benefit  of
     creditors;

          (6)  If  Tenant shall  commence any  case, proceeding or  other action
     seeking reorganization,  arrangement, adjustment,  liquidation, dissolution
     or composition of  it or its  debts under any  law relating to  bankruptcy,
     insolvency, reorganization or relief of debtors, or seeking  appointment of
     a receiver, trustee, custodian, or other similar official for it or for all
     or any substantial part of its property;

          (7)  If Tenant shall  take any corporate or other  action to authorize
     any  of the  actions set  forth above in  Subsections (5)  and (6)  of this
     Section 11A;

          (8)  If any case,  proceeding or other action against  Tenant shall be
     commenced seeking to have an order for relief entered against it as debtor,
     or   seeking   reorganization,    arrangement,   adjustment,   liquidation,
     dissolution or composition  of it or  its debts under  any law relating  to
     bankruptcy, insolvency,  reorganization or  relief of  debtors, or  seeking
     appointment of a receiver, trustee, custodian or other similar official for
     it or  for all  or any  substantial part  of its  property, and  such case,
     proceeding or other action (i) results in the entry of an  order for relief
     against it  which is not fully stayed within  seven (7) business days after
     the entry thereof  or (ii) remains undismissed  for a period of  sixty (60)
     days; or

          (9)  If Tenant does any act,  or other circumstance occurs, which this
     Lease provides is a default hereunder.

     B.   Landlord's Remedies.
          -------------------

          (1)  Upon  the occurrence  of  any  one or  more  defaults by  Tenant,
     Landlord may elect,  by written notice to  Tenant, to terminate  this Lease
     and Tenant's right to the Premises  as of the date set forth in  the notice
     or,  without  terminating  this  Lease,  to  terminate  Tenant's  right  to
     possession  of the Premises as of  the date set forth  in the notice.  Upon
     any termination of  this Lease, whether by  lapse of time or  otherwise, or
     upon any termination of Tenant's right to possession without termination of
     the Lease,  Tenant shall surrender  possession and vacate the  Premises and
     deliver  possession thereof  to  Landlord,  and  Tenant  hereby  grants  to
     Landlord  full and free  license to enter  into and upon  the Premises with
     process of law and  upon notice, and to repossess Landlord  of the Premises
     as of Landlord's former estate and to expel or remove Tenant and any others
     who may be occupying or  be within the Premises and  to remove any and  all
     property  therefrom using  such force  as  may be  necessary without  being
     deemed in any  manner guilty  of trespass,  eviction or  forcible entry  or
     detainer, and without relinquishing Landlord's  rights to rent or any other
     right given to Landlord hereunder or by law or in equity.















                                      -21-

<PAGE>
          (2)  If Tenant voluntarily abandons the Premises or otherwise entitles
     Landlord to  elect to terminate  Tenant's right to possession  only without
     terminating  the  Lease,  and  Landlord  does so  elect,  Landlord  may  at
     Landlord's option enter into the  Premises, remove Tenant's signs and other
     evidences of tenancy, and take and hold  possession thereof as set forth in
     subsection  B(1) of  this Section  11,  without such  entry and  possession
     terminating the  Lease or  releasing  Tenant, in  whole  or in  part,  from
     Tenant's obligation to  pay the rent hereunder  for the full Term,  and, at
     Landlord's option,  the present value of  the aggregate amount of  the Base
     Rent, Operating  Cost Share Rent and Tax Share  Rent (based upon the amount
     thereof for the calendar month immediately preceding the month in which the
     default has occurred)  for the period from  the date stated in  the written
     notice terminating possession to the stated  end of the Term (such  present
     value to be computed  on the basis  of a per annum  discount rate equal  to
     three (3) percentage  points below the Corporate  Base Rate at the  time of
     the default)  shall be immediately  due and payable by  Tenant to Landlord,
     together with any other monies due hereunder, and Landlord shall have right
     to immediate recovery of all  such amounts.*  In the  alternative, Landlord
     shall have the right from time to time, to recover from Tenant,  and Tenant
     shall  remain liable  for, all  rent not  theretofore accelerated  and paid
     pursuant to the  foregoing sentence and any other  sums thereafter accruing
     as  they become due under this Lease during the period from the date stated
     in the notice terminating  possession to the stated end of  the Term.  Upon
     and after entry  into possession without termination of  the Lease, subject
     to  Landlord's right  to first  rent other  vacant areas  in the  Building,
     Landlord may relet the Premises or any part  thereof to any person, firm or
     corporation other than Tenant for such rent, for such time (which may be  a
     period extending beyond the stated Term of this Lease) and upon  such terms
     as Landlord  in Landlord's  sole discretion  shall determine, and  Landlord
     shall not  be required to accept any tenant offered by Tenant or to observe
     any instructions  by Tenant relating to such reletting.   In any such case,
     Landlord may make repairs, alterations and additions in  or to the Premises
     and  redecorate the  same to the  extent deemed  necessary or  desirable by
     Landlord,  and in connection therewith Landlord may change the locks to the
     Premises,  and Tenant  shall  upon  written demand  pay  the cost  thereof,
     together  with Landlord's  expenses of  reletting.   Any proceeds  from the
     reletting of the  Premises by Landlord shall  be collected by Landlord  and
     shall first be  applied against  the cost  and expenses of  reentry and  of
     reletting  the  Premises including,  but  not  limited to,  all  brokerage,
     advertising, legal, alteration,  redecoration, repair and  other reasonably
     necessary  costs  and expenses  incurred to  secure  a new  tenant  for the
     Premises, and second to the payment of  rent herein provided to be paid  by
     the Tenant.    If the  consideration collected  by Landlord  upon any  such
     reletting, after payment of the expenses of reletting the Premises,  is not
     sufficient  to pay  monthly the full  amount of  the rent reserved  in this
     Lease, Tenant shall pay to Landlord  the amount of each monthly  deficiency
     as it becomes due  (as the case may be).  If the consideration collected by
     Landlord upon any such reletting for Tenant's  account after payment of the
     expenses of reletting the Premises is greater than



                                      -22-

*    Provided Landlord  recovers all such  amounts from Tenant  and subsequently
     relets the  Premises,  the  Tenant  shall  be entitled  to  a  refund  from
     Landlord,  but only  to the  extent  that Landlord  has mitigated  Tenant's
     damages.





<PAGE>
     the amount necessary to pay the full amount of Rent reserved in this Lease,
     the full  amount of such  excess shall be  retained by  Landlord and in  no
     event shall be payable to Tenant.   No such reentry, repossession, repairs,
     alterations, additions  or reletting shall  be construed as an  eviction or
     ouster of Tenant  or as an  election on Landlord's  part to terminate  this
     Lease, unless written notice of such intention is given to Tenant, or shall
     operate  to  release  Tenant in  whole  or  in part  from  any  of Tenant's
     obligations hereunder.*

          (3)  If  Landlord shall decide to terminate this Lease, Landlord shall
     be  entitled to recover from Tenant all of  the amounts of rent accrued and
     unpaid for the  period up to and including the date of the termination, as
     well as all other additional sums for which Tenant is liable, or in respect
     of  which  Tenant  has  agreed  to indemnify  Landlord  under  any  of  the
     provisions of this Lease, which may then be owing and unpaid, and all costs
     and expenses including without limitation,  court costs and attorneys' fees
     incurred  by  Landlord  in  the  enforcement of  its  rights  and  remedies
     hereunder, and in addition, Landlord, at its sole option, shall be entitled
     to  recover from Tenant,  in lieu of  any amounts due  under Section 11B(2)
     hereof,  and  Tenant  shall  pay  to Landlord,  on  demand,  as  final  and
     liquidated  damages (and not  as a penalty),  a sum equal to  the amount of
     Landlord's  reasonable  estimate  of  the aggregate  amount  of  Base Rent,
     Operating Cost Share Rent, Tax Share Rent and Additional Rent that would be
     payable  for the  period from  the  date of  such  termination through  the
     Termination  Date, reduced  by  the  then reasonable  rental  value of  the
     Premises for the same period, both discounted  to present value at the rate
     per annum  equal to three  (3) percentage points  below the  Corporate Base
     Rate at the time of the default.  If, before presentation of  proof of such
     liquidated damages to  any court, commission or tribunal,  the Premises, or
     any part thereof, shall have been relet by Landlord for such period, or any
     part  thereof, the  amount of  rent payable  upon such  reletting shall  be
     deemed to be the  reasonable rental value for the part or  the whole of the
     Premises relet during the term of the reletting.

          (4)  Landlord may but  shall not be obligated  to cure any  default by
     Tenant hereunder, but,  if Landlord so elects, all costs  and expenses paid
     by Landlord in curing  such default and legal fees in  connection therewith
     shall be Additional Rent due on demand by Landlord.**

          (5)  Notwithstanding  anything in the  Lease to the  contrary, any and
     all remedies set forth  in this Lease (i)  shall be in addition to  any and
     all other remedies Landlord may have at law or in equity, and (ii) shall be
     cumulative.   The waiver by Landlord of any breach of any term, covenant or
     condition herein contained shall only be effective  if it is in writing and
     shall not be deemed to be a waiver of a  continuing or subsequent breach of
     the same,  or of  any other term,  covenant or condition  herein contained.
     The acceptance of  rent or  any other  amounts due hereunder  shall not  be
     construed to be a waiver  of any breach by Tenant of any  term, covenant or
     condition  of this  Lease, and  if  the same  shall be  accepted  after the
     termination  of  this Lease,  by  lapse of  time  or otherwise,  or  of the
     Tenant's right  of possession hereunder, or after the giving of any notice,
     such acceptance shall not  reinstate, continue or extend  the Term of  this
     Lease or affect any notice given to Tenant prior to the


                                      -23-

*    Notwithstanding  anything to  the contrary  herein,  Landlord shall  make a
     reasonable effort to  mitigate any damages  incurred by Tenant,  including,
     without limitation, reletting the Premises.

**   Landlord  agrees  that in  the event  that Tenant  succeeds in  obtaining a
     judgment against Landlord based on a default by Landlord  under this Lease,
     such judgment may include Tenant's reasonable attorneys' fees.


<PAGE>
     receipt of  such amounts, it being agreed that  after the service of notice
     or the commencement of a suit or after final judgment for possession of the
     Premises, Landlord may receive and collect any rent and other sums due, and
     the payment  of the same  shall not  waive or affect  said notice,  suit or
     judgment.

          (6)  Notwithstanding any  provision in this Lease prohibiting Landlord
     from exercising its rights hereunder or at law or in equity if Tenant cures
     a default within a specified period of time, if Tenant shall default (i) in
     the timely payment of rent (whether any or all of Base Rent, Operating Cost
     Share  Rent, Tax Share Rent or Additional Rent)  three or more times in any
     period  of  12  consecutive months,  or  (ii)  in  the performance  of  any
     particular term, condition or covenant of this Lease three or more times in
     any  period  of six  consecutive  months, then,  notwithstanding  that such
     defaults shall have each been cured within any applicable cure period after
     notice, if  any, as provided  in this  Lease, any  further similar  default
     (including, without limitation,  with respect to  non-payment of rent,  the
     further non-payment of any kind of rent payable under this Lease) shall not
     be curable  by Tenant and Landlord shall have the  right to exercise all of
     the remedies provided in this Lease (including, without limitation, any and
     all remedies at law and in equity) immediately after the occurrence of such
     similar default.

          (7)  If  the term  of any lease,  other than  this Lease, made  by the
     Tenant for any demised premises in the Building or any other building owned
     by Landlord or  an affiliate of Landlord  in the Chicago Metropolitan  area
     shall be terminated or terminable after the making of this Lease because of
     any default  by the Tenant under such other  lease, such fact shall empower
     the Landlord, at Landlord's sole option, to terminate this Lease by written
     notice to the Tenant.

          (8)  In  the event  that Tenant  shall file  for protection  under the
     Bankruptcy Code now  or hereinafter in  effect, or a trustee  in bankruptcy
     shall  be appointed  for Tenant,  Landlord and Tenant  agree to  the extent
     permitted by law, to  request that the debtor-in-possession  or trustee-in-
     bankruptcy, if one  shall have been appointed, assume or  reject this Lease
     within sixty (60) days thereafter.

     12.  HOLDOVER. If Tenant  retains possession  of the  Premises or  any part
thereof after the termination of the Term or any extension thereof, by lapse  of
time or otherwise, Tenant  shall become a tenant  from month-to-month only  upon
each and all of the terms herein provided as may be applicable to such month-to-
month  tenancy and any  such holding over  shall not constitute  an extension of
this Lease;  provided, however, that during such  holding over, Tenant shall 
pay Base Rent, Operating Cost Share Rent and Tax Share Rent at 150% of the rate 
payable for  the fiscal  year, or  portion thereof,  immediately preceding  
said holding over, computed on a monthly basis for the time Tenant thus remains
in possession and, in addition, Tenant  shall pay Landlord all damages, 
consequential  as well as  direct, sustained by reason of Tenant's holding over.
Alternatively, after ninety (90) days  after expiration of  this Lease, at  the 
election of  Landlord expressed in a written notice to Tenant and not otherwise,
such retention of possession shall constitute a renewal of this Lease for one 
(1)  year; provided, however, that Tenant shall pay  Base Rent in an amount 
equal to the greater  of 150% of the rate payable for  the immediately preceding
fiscal year, or  portion thereof or 150% of the then current  market rate as 
determined by Landlord,  and Tenant shall continue to make all other payments 
required under this Lease,









                                      -24-

<PAGE>
including, without  limitation, Operating  Cost Share Rent  and Tax  Share Rent.
Neither  the acceptance  of rent  by  the Landlord  after  termination, nor  the
provisions of this Section:  (i) shall be construed as, or operate as, a renewal
or as a waiver of Landlord's right of re-entry or right to regain possession  by
actions  at law or in equity or by  any other right or remedy hereunder; or (ii)
shall be construed as, or operate  as, a waiver of any other right  or remedy of
Landlord.

     13.  SUBORDINATION TO MORTGAGES, TRUST DEEDS AND GROUND LEASES.

     A.   Subordination.  This Lease shall be subordinated to any and all Ground
          -------------
Leases now or hereafter  in force with respect to the Project at the election of
the ground lessor under any  such Ground Lease, provided that so  long as Tenant
is  not in default  under this Lease  its tenancy will  not be  disturbed.  This
Lease shall be subject to all of the terms and conditions of such Ground Leases,
which are hereby incorporated in this Lease by this reference,  and in the event
of any  conflict between  the terms  hereof and  the  terms of  any such  Ground
Leases, the  terms of  such Ground Leases  shall control.   This Lease  shall be
subordinated to  the lien  of any and  all mortgages  now or hereafter  in force
against (a) the Project  and (b) any and  all Ground Leases with respect  to the
Project, at the election of the mortgagee under any such mortgage, provided that
so long  as Tenant is not  in default under this  Lease its tenancy will  not be
disturbed.  Landlord hereby represents that as  of the date hereof there are no
Ground Leases with respect to the Project.

     The respective rights to  so subordinate this Lease at the  election of any
such ground  lessor or mortgagee  shall continue during any  amendment, renewal,
modification,  consolidation, replacement or extension of each such Ground Lease
or mortgage, and shall apply to  any and all advances made or hereafter  made on
the security of each such mortgage.

     Subordination shall be effective at  election of any such ground lessor  or
mortgagee.  Election shall  not be dependent on  receipt of notice by Tenant  of
the  election to  subordinate.   Without limiting the  foregoing, notice  of the
election to subordinate  may be given as  provided for notices pursuant  to this
Lease.

     Any subordination  at the election  of any such ground  lessor or mortgagee
shall be  self-operating.   Nevertheless, Tenant or  its successors  in interest
upon  request of  Landlord shall promptly  execute and deliver  (within ten (10)
days after  a request  therefor) at  any time  and from  time to  time upon  the
request of Landlord, such instruments as are reasonably necessary or appropriate
in Landlord's judgment to evidence such subordination.

     B.   Termination of  Ground Lease or  Foreclosure of Mortgage.   Should any
          --------------------------------------------------------
mortgage on the Project  or on any Ground Lease be foreclosed  or if any Ground
Lease be terminated and this Lease be continued:

          (1)  The  liability of the  mortgagee, ground  lessor or  purchaser at
     such  foreclosure sale  shall exist  only during  the time  such mortgagee,
     ground lessor or purchaser is the owner of the Project.

          (2)  Tenant  shall  attorn, as  Tenant under  this Lease,  without any
     deductions or setoffs whatsoever, to  the purchaser at the foreclosure sale
     (or the  mortgagee if  the mortgagee  becomes owner  of the  fee estate  or
     lessor under any  Ground Lease) or, if  any Ground Lease be  terminated for
     any reason, Tenant  shall be deemed to  have attorned as Tenant  under this
     Lease to







                                      -25-

<PAGE>
     the ground lessor under the Ground Lease, and this Lease shall  continue in
     full force and effect as a direct lease between and binding upon Tenant and
     such mortgagee or ground lessor, as the case may be.  Likewise, Tenant will
     attorn to a leasehold  mortgagee in the event a leasehold  mortgagee should
     ever become the  owner of the leasehold  estate covered by its  mortgage or
     should become the  owner of any new lease in replacement or substitution of
     such  leasehold estate.   Tenant  agrees  to promptly  execute and  deliver
     (within ten (10) days after a  request therefor) at any time and  from time
     to time upon  the request of  Landlord, or of  any ground lessor  under any
     such Ground  Lease, or of any holder of any such mortgage or leasehold
     mortgage, or of any such purchaser,  any instrument which, in the sole 
     judgment of such requesting party, may be necessary or  appropriate in any
     such  foreclosure or  termination proceeding  or otherwise  to evidence 
     such attornment.

          (3)  As used in this Section 13, "mortgage" shall include "trust deed"
     and "mortgagee" shall include "trustee"  and successors and assigns of such
     party (whether immediate or remote), the purchaser of any mortgage, whether
     at foreclosure or  otherwise and the successors, assigns  and mortgagees of
     such purchaser (whether immediate or remote).


     C.   Security Deposit.   The mortgagee  under  a mortgage  and  the  lessor
          ----------------
under  any  Ground Lease  shall have  no  responsibility for  the return  of the
security  deposit, if any, except to the extent  the security deposit is held by
such mortgagee or  ground lessor in which  case such mortgagee or  ground lessee
shall be obligated to return the security deposit.

     D.   Notice and  Right to Cure.   Landlord  hereby notifies Tenant that the
          -------------------------
Project  is subject to the mortgages,  if any, set forth  on Appendix E attached
hereto (Mortgages Currently Affecting the Project), and Landlord agrees promptly
to notify Tenant  of the placing of  any additional Ground Leases,  mortgages or
trust deeds against the real property or  leasehold estate of which the Premises
form a part.

     Tenant agrees to  give the  mortgagees shown  on Appendix E  and any  other
mortgagee or  holder  of a  deed of  trust or  lessor  of any  Ground Lease,  by
registered mail,  a copy  of any  notice of  default served  upon the  Landlord,
simultaneously with Tenant's delivery of notice to Landlord, provided that prior
to  such  notice Tenant  has been  notified,  in writing  (by  way of  notice of
Assignment of Rents and Leases, or otherwise), of the address of such mortgagee,
holder of a  deed of trust  or lessor  under any Ground  Lease.  Tenant  further
agrees that if Landlord shall have failed  to cure such default within the  time
provided for  in this Lease, then such  mortgagee, holder of a deed  of trust or
lessor under any Ground Lease shall have an additional ten (10) days within 
which to cure such default, or if such default cannot be  cured within that 
time, such mortgagee, holder of a deed of trust or lessor under any Ground 
Lease shall have such additional time  as may be  necessary to cure  such 
default, provided that within such ten (10) days, any mortgagee, holder of a 
deed of trust  or lessor under any  Ground Lease,  as the case  may be, has  
commenced and  is diligently pursuing the cure of such default (including  but 
not limited to commencement of foreclosure or lease forfeiture proceedings,  if
necessary to effect such cure), and Tenant shall not pursue any of the remedies
it may have for such default and this Lease shall not be terminated, while such
cure is being diligently pursued, so long as  the default is completely cured 
within a reasonable time thereafter. During the  period  between the  giving  
of such  notice  and the  remedying  of Landlord's default, the rent herein 
recited shall be abated and









                                      -26-

<PAGE>
apportioned to the extent that any part of the Premises shall be untenantable.

     14.  ASSIGNMENT AND SUBLETTING BY TENANT.

     A.   Tenant shall  not, without  the prior written  consent of  Landlord in
each instance, (i) assign,  transfer, mortgage, pledge, hypothecate or  encumber
or subject  to or permit to  exist upon or be  subjected to any lien  or charge,
this Lease or any interest under  it, (ii) allow to exist or occur  any transfer
of or lien upon this Lease or  the Tenant's interest herein by operation of law,
(iii)  sublet the  Premises or  any  part thereof,  or  (iv) permit  the use  or
occupancy  of the Premises or any part thereof  for any purpose not provided for
under Section 6 of  this Lease or by anyone  other than the Tenant and  Tenant's
employees.  In no event  shall this Lease or any interest herein  be assigned or
assignable by voluntary or involuntary bankruptcy proceedings or by operation of
law or otherwise, and in no  event shall this Lease or any rights  or privileges
hereunder  be   an  asset  of   Tenant  under  any  bankruptcy,   insolvency  or
reorganization proceedings, except to the extent provided by law.

     B.   Consent by  Landlord to  any assignment,  subletting, use,  occupancy,
transfer or encumbrance  shall not operate to relieve Tenant  from any covenant,
liability or obligation hereunder (whether  past, present or future), including,
without limitation, the  obligation to pay rent,  except to the extent,  if any,
expressly provided for in such consent, nor shall such consent be deemed to be a
consent to  any subsequent assignment,  subletting, use, occupancy,  transfer or
encumbrance.   Tenant shall pay  all of  Landlord's costs, charges  and expenses
(including, without limitation, reasonable attorneys' fees) not to exceed $1,000
incurred in connection with any assignment, subletting, use, occupancy, transfer
or encumbrance made or requested by Tenant.

     C.   Tenant shall, by  notice in writing, advise Landlord  of its intention
from, on and after  a stated date (which shall not be less  than sixty (60) days
after the date of Tenant's  notice) to assign this Lease  or sublet any part  or
all of the Premises for the balance or any part of the Term, and, in such event,
Landlord shall  (except in the event that the  proposed assignee or sublessee is
affiliated with Tenant such  that at least 20% of the interest  in such assignee
or sublessee  is held  by Tenant,  the owners  of Tenant,  or those  controlling
Tenant) have  the right,  to be  exercised by  giving written  notice to  Tenant
within thirty  (30) days after  receipt of  Tenant's notice,  to terminate  this
Lease with respect  to the  space described in  Tenant's notice as  of the  date
stated  in Tenant's  notice for the  commencement of the  proposed assignment or
sublease.*  Tenant's notice  shall include the name and address  of the proposed
assignee or subtenant,  a true and complete  copy of the proposed  assignment or
sublease  and  sufficient information  as  Landlord  deems necessary  to  permit
Landlord to determine the financial responsibility and character of the proposed
assignee  or subtenant.   If Tenant's notice  covers all of  the Premises and if
Landlord exercises its right  to terminate this Lease as to such space, then the
Term  of this Lease  shall expire  and end  on the  commencement date  stated in
Tenant's notice as fully and completely as if that date had been the Termination
Date.  If, however, Tenant's notice covers less than all of the Premises, and if
Landlord exercises its right to terminate this  Lease with respect to such space
described  in Tenant's  notice,  then  as of  the  commencement date  stated  in
Tenant's notice, the rent reserved herein shall be  adjusted on the basis of the
number of rentable square feet retained by Tenant, and this Lease as so amended,
shall continue thereafter in full force and effect.  If Landlord, upon receiving
Tenant's notice, does not exercise its right to terminate as aforesaid, Landlord
will  not unreasonably withhold its consent to Tenant's assignment of this Lease
or subletting the space covered by its notice.



                                      -27-

*    If  Landlord does not elect to  exercise Landlord's right to terminate with
     respect to such space, then Tenant may market such space thereafter without
     providing Landlord  further notice  or opportunity  to terminate,  provided
     Tenant has been continuously marketing such space.

<PAGE>
Without limitation, it shall  be deemed reasonable for Landlord  to withhold its
consent to Tenant's assignment of this Lease  or subletting the space covered by
its notice if the proposed assignee or sublessee is a  tenant or occupant of the
Building or an  affiliate (a person controlling,  controlled by or under  common
control  with) of  a tenant  or occupant  of the  Building, unless  there is  no
comparable  space  available  in  the  Building for  such  tenant,  occupant  or
affiliate.

     D.   If Tenant, having first obtained Landlord's consent to  any assignment
or sublease, or if Tenant or a trustee in bankruptcy  for Tenant pursuant to the
Bankruptcy Code, shall  assign this Lease  or sublet the  Premises, or any  part
thereof, at a  rental or for other  consideration in excess of the  aggregate of
the Base Rent, Operating Cost  Share Rent and Tax Share Rent due  and payable by
Tenant under this  Lease, then Tenant shall  pay to Landlord as  Additional Rent
40% of  such  excess rent  or other  consideration within  ten  (10) days  after
receipt thereof from time to time.

     E.   If Tenant  shall assign this  Lease as permitted herein,  the assignee
shall expressly  assume all of the obligations of  Tenant hereunder and agree to
comply with and be bound by all of  the terms, provisions and conditions of this
Lease,  in  a written  instrument  satisfactory  to  Landlord and  furnished  to
Landlord not later  than fifteen (15)  days prior to  the effective date  of the
assignment.  If Tenant  shall sublease the Premises as  permitted herein, Tenant
shall obtain and furnish to Landlord, not later than fifteen (15)  days prior to
the effective date  of such sublease and  in form satisfactory to  Landlord, the
written agreement of such  subtenant that it shall  comply with and be  bound by
all  of the  terms, provisions  and conditions of  this Lease  and that  it will
attorn to Landlord, at Landlord's option and written request, in the  event this
Lease terminates before the expiration of the sublease.

     F.   If Tenant  is a corporation  whose stock  is not publicly  traded, any
transaction  or series  of  transactions  (including,  without  limitation,  any
dissolution,  merger, consolidation  or other  reorganization of Tenant,  or any
issuance, sale,  gift, transfer or  redemption of any  capital stock of  Tenant,
whether voluntary, involuntary or by operation of law, or any combination of any
of the foregoing  transactions) resulting in the transfer of  control of Tenant,
other than by  reason of death or  to a descendant or spouse  of such transferor
for estate planning  purposes, shall be deemed  to be a voluntary  assignment of
this Lease by Tenant subject to the provisions of this Section 14.  If Tenant is
a partnership,  any  transaction or  series of  transactions (including  without
limitation  any  withdrawal or  admittance of  a  partner or  any change  in any
partner's interest in Tenant, whether  voluntary, involuntary or by operation of
law, or  any combination of any of the  foregoing transactions) resulting in the
transfer of control of Tenant, other than by reason of death, shall be deemed to
be a  voluntary assignment of this Lease by Tenant  subject to the provisions of
this Section 14.  The term "control" as used in this Section 14F means the power
to directly or  indirectly direct or  cause the direction  of the management  or
policies of Tenant.  If  Tenant is a corporation, a change or  series of changes
in ownership of stock which would result in direct or indirect change in 
ownership of less than fifty percent (50%) of the outstanding stock of Tenant
as  of  the date  of the  execution  and delivery  of  this Lease  shall  not be
considered a change of control.*

     G.   Any assignment, subletting, use, occupancy, transfer or encumbrance of
this Lease or  the Premises without Landlord's prior written consent shall be of
no effect and shall, at the option of Landlord, constitute  a default under this
Lease.**

CONTINUATION OF SECTION 14F
- ---------------------------

Notwithstanding the foregoing, an initial public offering by Tenant shall not be
deemed an assignment of this Lease.


CONTINUATION OF SECTION 14:
- --------------------------

     H.   Upon delivery to Landlord by any assignee to whom this Lease may be
assigned (and who has been approved by Landlord in accordance with this Section
14), of a written agreement of such assignee to assume all the terms, covenants
and conditions of this Lease to be performed by Tenant and to be bound thereby,
the Tenant so assigning this Lease shall thereafter be released and discharged
from any obligations thereafter arising under this Lease.

     I.   Landlord agrees that it shall be deemed unreasonable for Landlord to
withhold its consent to a proposed assignment or sublease based on the
creditworthiness of the proposed assignee or sublessee where such proposed
assignee or sublessee has a net equity (meaning total assets less total
liabilities) equal to or greater than $2,000,000.00













































<PAGE>
     15.  SALE BY LANDLORD.   In the event of sale or  conveyance or transfer by
Landlord of its interest in the Project or in the Building or in this Lease, the
same  shall operate  to release  Landlord (subject  to the  second paragraph  of
Section 17 hereof) from any future obligations and any future liability  for or
under  any of the covenants or  conditions, express or implied, herein contained
in  favor of Tenant,  and in such  event, and with  respect to such obligations,
covenants and  conditions, Tenant  agrees  to look  solely  to the  successor in
interest of Landlord in  and to this Lease which successor  Landlord shall, from
and after  the date of  transfer, become  liable for Landlord's  obligations and
covenants hereunder.    This Lease  shall  not be  affected  by any  such  sale,
conveyance or transfer.

     16.  ESTOPPEL CERTIFICATE.   Landlord shall, at the request  of Tenant, and
Tenant shall, at the request of Landlord at any time and from  time to time upon
not  less  than ten  (10) days'  prior written  notice, execute,  acknowledge in
recordable form, and deliver to the other (or for the Tenant to its auditor or a
prospective purchaser of its business or assets, or to its assignee or subtenant
if acceptable  to Landlord,  or for  the Landlord to  Landlord's mortgagee,  the
lessor  under  any Ground  Lease, auditors  or  a prospective  purchaser  of the
Project or any part thereof) a certificate stating that this Lease is unmodified
and in  full  force and  effect (or,  if modified,  stating the  nature of  such
modification and certifying  that this Lease, as  so modified, is in  full force
and effect),  and the dates to  which the rent  and other charges are  paid, and
that Tenant  is paying rent  on a current basis  with no offsets  or claims, and
there are not,  to Tenant's or  Landlord's knowledge,  as the case  may be,  any
uncured defaults on the part of Landlord or of Tenant (or specifying such 
offsets, claims or defaults, if any are claimed).  Such certificate may require
the party giving it to specify the date of commencement of rent, the 
Commencement Date, the Termination Date, the  Base Rent, current Operating Cost
Share  Rent and Tax Share  Rent estimates,  the date  to which  rent has been 
paid, whether  or not Landlord has completed any improvements required to be 
made to the  Premises and such other matters  as may be required.   It is 
expressly understood  and agreed that any  such statement  may be  relied upon
by any  prospective purchaser  or encumbrancer of all or any portion of the  
Project or by any ground lessor, or by a purchaser  or assignee  or lender  to 
Tenant or  to auditors  of either  party hereto or by any other person  to whom
it is delivered.  The  failure to deliver such statement within  the time 
required hereunder  shall, at the option  of the requesting party,  be a default
under this  Lease, or  be conclusive  evidence, binding upon  the  nonperforming
party  that this  Lease is  in  full force  and effect,  without modification  
except as  may be  represented by  the requesting party, that  there are no 
uncured defaults by  the requesting party and that not more than one (1) month's
rent has  been paid in advance, and the  nonperforming party shall be estopped 
from asserting any defaults known to it at that time.

     17.  SECURITY DEPOSIT.  Tenant has deposited with Landlord security for the
full and  faithful performance of every provision of  this Lease to be performed
by Tenant in the amount, if any, set forth as Item 9 in the Schedule.  If Tenant
defaults  with respect to any  provision of this Lease, Landlord  may use all or
any part  of this  security deposit for  the payment of  any rent and any other
sum due or in default, or for the payment of any other  amount which Landlord 
may spend or  become obligated to spend by reason  of Tenant's default, or to 
compensate  Landlord for any loss  or damage which Landlord may  suffer by
reason of  Tenant's default.   If any  portion of  such deposit is  to be  used,
Tenant shall  within five (5)  days after  written demand therefor  deposit cash
with Landlord  in an amount  sufficient to restore  the security deposit  to its
original amount and Tenant's failure to do so shall be a material breach of this
Lease.  Landlord shall not be









                                      -29-

<PAGE>
required  to keep this security  deposit separate from  its general funds Tenant
shall not be  entitled to interest on  such deposit.  If Tenant  shall fully and
faithfully  perform every  provision of this  Lease to  be performed by  it, the
security deposit  or any  balance thereof shall  be returned  to Tenant  (or, at
Landlord's  option, to the last assignee  of Tenant's interest hereunder) at the
expiration of this  Lease and upon vacation  of the Premises in  accordance with
the  provisions hereof.   Said security deposit  shall not be  deemed an advance
payment of rent or a measure of Landlord's damages  for any default hereunder by
Tenant.*

     Tenant acknowledges that Landlord has the right to transfer all or any part
of its  interest in  the Project or  this Lease, and  Tenant agrees that  in the
event of  any such  transfer, Landlord  shall have  the right  to transfer  such
security deposit to the transferee.  Upon delivery by Landlord to Tenant of such
transferee's  written acknowledgment  of its  receipt of such  security deposit,
Landlord shall  thereby be released  by Tenant from all  liability or obligation
for  the  return  of such  deposit  and Tenant  agrees  to look  solely  to such
transferee for the return of the security deposit.

     18.  EXCUSE OF  PARTY'S INABILITY TO  PERFORM; PARTY'S DEFAULT.   Except as
specifically  provided  to  the  contrary in  this  Lease,  this  Lease  and the
obligation of Tenant to pay rent hereunder and perform all of Tenant's covenants
and agreements hereunder shall  not be impaired nor shall Landlord  or Tenant be
in  default hereunder because Landlord or Tenant, as  the case may be, is unable
to fulfill any  of its obligations under  this Lease, if Landlord or  Tenant, as
the  case may be, is prevented or delayed  from so doing by any of the following
(which shall  be  referred  to  herein as  a  "Force  Majeure"):  any  accident,
breakage, repairs, alterations,  improvements, strike or labor troubles,  or any
other cause whatsoever beyond the reasonable control of Landlord, including, but
not limited to, energy shortages or governmental preemption in connection with a
national  emergency, or  by reason  of  government laws  or any  rule,  order or
regulation of any department of  subdivision thereof of any governmental agency,
or  by reason  of the conditions  of supply  and demand  which have been  or are
affected by war or other emergency.

     20.  NOTICES.  All  notices and approvals are  to be given by  one party to
the other party under this Lease shall be given in writing,  mailed or delivered
as follows:

Lease from Landlord.

          Attn:  Building Manager

or to such other person at such other address designated by notice to Tenant.

     B.   To Tenant at the place set forth as Item 10 on the Schedule until
Tenant takes possession of the Premises, and thereafter at the Premises or at
such other address designated by notice to Landlord.

     Mailed notices shall be sent by United States Certified or Registered Mail,
postage prepaid.  Mailed notices shall be deemed to have been given three (3)
business days after posting in the United States mails, and notices delivered
personally shall be deemed to have been given upon delivery or attempted
delivery.

     21.  QUIET POSSESSION.  So long as Tenant shall observe and perform the
covenants and agreements binding on it  hereunder, Tenant shall at all times
during the Term herein granted and subject to the provisions of this Lease
peacefully and quietly have and enjoy the possession of the Premises without any
encumbrance or hinderance by, from or through Landlord, its successors or
assigns.

     22.  REAL ESTATE BROKER.  Tenant represents that it has not dealt with any
real estate broker except for Miglin-Beitler Management Corporation and that
broker listed, if any, in Item 11 in the Schedule, with respect to this Lease
and, to its knowledge no other broker initiated or participated in the
negotiation of this Lease, submitted or showed the Premises to Tenant or is
entitled to any commission in connection with this Lease.  Tenant agrees to
indemnify and hold Landlord harmless from all claims from any other real estate
broker for commission or fees in connection with this Lease.

     23.  CONDEMNATION.  If all or any portion of the Project or Premises are
taken by eminent domain so that the Premises cannot be reasonably used by Tenant
for the purposes for which they are demised, then at the option of either party
this Lease may be terminated effective as to the date of such taking.  The
entire award for any total or partial taking shall be paid to and retained by
Landlord.  If any condemnation proceeding shall be instituted in which it is
sought to take or damage any part of the Project, or if the grade of any street
or alley adjacent to the project is changed by any competent authority and such
change of grade makes it necessary or desirable to remodel the Project to
conform to the changed grade, Landlord shall have the right to terminate this
Lease upon not less than ninety (90) days' notice prior to the date of
termination designated in the notice.  No money or other consideration shall be
payable by Landlord to Tenant for said termination. *

     24.  SPRINKLERS.  If the sprinkler system installed at the Project or any
of its appliances shall be damaged or injured or not in proper working order by
reason of any act or omission of Tenant, Tenant's agents, servants, employees,
licensees or invitees, Tenant shall forthwith restore the same to good working
condition at its own expense.  Tenant shall not do or permit anything to be done
upon the Premises, or bring or keep anything thereon which is in violation of

CONTINUATION OF SECTION 23:
- --------------------------

Nothing contained in this Section 23 shall prohibit Tenant from instituting
separate proceedings to pursue a separate award compensating it for relocation,
business loss and other costs incurred by Tenant in connection with a
condemnation or taking (including, but not limited to, rent differentials,
brokerage and attorney fees, and unamortized improvements in the Premises), as
long as such award in no way reduces the award otherwise payable to Landlord.

Bureau, Fire Insurance Rating Organization or any similar authority having 
jurisdiction over the Building, and if the Board of Fire Underwriters or Fire 
Insurance Exchange or any bureau, department or official of the state or city 
government, requires or recommends that any changes, modifications, alterations
or additional sprinkler heads or other equipment be made or supplied by reason 
of Tenant's business or acts or the location of partitions, trade fixtures, or 
other contents of the Premises, or if any such changes, modifications, 
alterations, additional sprinkler heads or other equipment, become necessary 
to prevent the imposition of a penalty or charge against the full allowance for
a sprinkler system in the fire insurance rate as fixed by said Exchange, or by
any fire insurance company, Tenant shall, at Tenant's expense, promptly make 
and supply such changes, modifications, alterations, additional sprinkler heads
or other equipment.

     25.  MISCELLANEOUS.

     A.   Covenants Binding on Successors.  Subject to the terms and provisions
          -------------------------------

thirty (30) days from the date Landlord renders statements of account therefor
and shall bear interest at the rate provided in Section 2D(3) from the date due
until paid.

     C.   Meaning of "Re-entry" and "Landlord".  The words "re-enter" and "re-
          ------------------------------------
entry" as used in this Lease are not restricted to their technical legal
meaning.  The term "Landlord," as used in this lease, means only the landlord
from time to time, and upon conveying or transferring its interest, such
conveying or transferring landlord shall be relieved from any further obligation
or liability pursuant to Section 13B(1), 13C, 15 and 17 of this Lease.

     D.   Time is of the Essence.  Time is of the essence of this Lease and each
          ----------------------
and all of its provisions.

     E.   No Option.  Submission of this instrument for examination or signature
          ---------
by Tenant does not constitute a reservation of or option for lease, and it is
not effective as a lease or otherwise until execution and delivery by both
Landlord and Tenant.

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

          ------------------
this Lease, which modification will not bring about any increased cost or 
expense to Tenant or in any other way substantially change the rights and 
obligations of Tenant hereunder, Tenant agrees that this Lease may be so 
modified.









                                      -32-

<PAGE>
     I.   No Oral Modification.  No subsequent alteration, amendment, change or
          --------------------

          --------------------------------
arbitration between the parties hereto with respect to the enforcement or
interpretation of this Lease, the nonprevailing party shall pay the attorney's
fees, court costs and other costs of the prevailing party, provided that Tenant
shall notify Landlord of any alleged breach of Landlord's obligations under this
Lease and shall take no action with respect to such breach as long as Landlord
immediately commences to cure and diligently proceeds to complete the cure of
said breach within a reasonable time period.  Each party hereto shall pay the
attorney's fees, court costs (if any) and other costs incurred by the other
party in any litigation, negotiation or transaction in which such party causes
the other party, without the other party's fault, to become involved or
concerned (including, without limitation, any request for Landlord's consent to
a sublet or assignment).

     K.   Captions.  The marginal headings and titles to the paragraphs of this
          --------

Authority to Execute This Lease.  All rights and remedies of Landlord under this
- -------------------------------
Lease, or that may be provided by law, may be exercised by Landlord in its own
name individually, or in its name by any agent thereof, and all legal
proceedings for the enforcement of any such rights or remedies may be commended
and prosecuted to final judgment and executed by Landlord in its own name
individually or in its name by any agent thereof.  Landlord and Tenant each
represents to the other that each has full power and authority to execute this
Lease and to make and perform the agreements herein contained.

     M.   Payments to Affiliates.  Nothing in this Lease shall be construed to
          ----------------------
prevent Landlord from paying for services rendered or materials delivered with
respect to the Project or to the Premises (including, without limitation,
management services and contracting out capital improvements or other capital
repairs or construction items) by affiliates of Landlord provided that the fees
or costs of such services and materials are at market rates in the Northbrook
area.  All such fees or costs paid by Landlord to such affiliates shall be
deemed to constitute Operating Costs on the same terms and conditions as if such
fees and costs were paid to non-affiliates of Landlord.

     N.   Entire Agreement.  This Lease (including, without limitation, any
          ----------------
Rider attached hereto and signed by both parties and Appendices A through E, all
                                                                          -
of which are incorporated herein by this reference) constitutes the entire
agreement between the Landlord and the Tenant.  Tenant acknowledges that it has
not been induced to enter this Lease by any promises, assurances, agreements,

relied on any such Representations, agrees that no such Representations shall 
be used in the construction or interpretation of this Lease and agrees that 
Landlord shall have no liability for any consequences arising as a result of 
any such Representations.

<PAGE>
     O.   Landlord's Title.  Landlord's title is and always shall be paramount
          ----------------
to the interest of Tenant, and nothing herein contained shall empower Tenant to
do any act which can, shall or may encumber Landlord's title.

     P.   Light and Air Rights.  This Lease does not grant any rights to light
          --------------------
or air over or about the Project.  Landlord specifically excepts and reserves to
itself the use of any roofs, the exterior portions of the Premises, all rights
to and the land and improvements below the improved floor level of the Premises,
the improvements and air rights above the Premises and the improvements and air
rights located outside the demising walls of the Premises, and such areas within
the Premises as were required for installation of utility lines and other
installations required to serve any occupants of the Building and the right to
maintain and repair the same, and no rights with respect thereto are conferred
upon Tenant unless otherwise specifically provided herein.

     Q.   Consents.  Except as otherwise expressly set forth herein (including,
          --------
without limitation, Sections 4E, 5B, 10B and 11B(2)), wherever the consent or

Lease, such party shall not unreasonably withhold or delay such consent or 
approval.

          -----------------
hereunder may be exercised by Landlord or any of its agents, employees,

          -----------------------------
whenever used in this Lease shall be construed to mean the plural where
necessary, and the necessary grammatical changes required to make the provisions
hereof apply either to entities or individuals, or men or women, shall in all
cases be assumed as though in each case fully expressed.

     T.   Rent Not Based on Income.  It is agreed by Landlord and Tenant that no
          ------------------------
rental or other payment for the use, occupancy or utilization of the Premises
demised hereunder shall be, or is, based in whole or in part on the net income
or profits derived by any person from the Building or the Premises so leased,
used, occupied, or utilized, and Tenant further agrees that it will not enter
into any sublease, license, concession or other agreements for any 
use, occupancy or utilization of the Premises which provides for a rental or 
other payment for such use, occupancy or utilization based in whole or in part 
on the net income or profits derived by any person from the Premises so leased,
used, occupied or utilized.

     U.   Exclusivity.  Tenant is not granted by this Lease and shall not be
          -----------
entitled to have any exclusive rights in the Building other than the rights of
its occupancy.

     V.   No Recording by Tenant.  Tenant shall not record or file in any public
          ----------------------
records this Lease or any portion thereof.

     26.  UNRELATED BUSINESS INCOME.

     A.   Landlord shall have the right at any time and from time to time to
unilaterally amend the provisions of this Lease, if Landlord is advised by its
counsel that all or any portion of the monies paid by Tenant to Landlord
hereunder are, or may be deemed to be, unrelated business income within the
meaning of the United States Internal Revenue Code or regulations issued
thereunder, and Tenant agrees that








                                      -34-


<PAGE>
it will execute all documents or instruments necessary to effect such amendment
or amendments, provided that no such amendment shall result in Tenant having to
pay in the aggregate more money on account of its occupancy of the Premises
under the terms of this Lease, as so amended, and provided further that no such
amendment shall result in Tenant receiving fewer services or services of a
lesser quality than it is presently entitled to receive under this Lease.

     B.   Any services which Landlord is required to furnish pursuant to the
provisions of this Lease may, at Landlord's option, be furnished from time to
time, in whole or in part, by employees of Landlord or the building manager of
the Project or its employees or by one or more third persons hired by landlord
or the building manager of the Project.  Tenant agrees that upon Landlord's
written request it will enter into direct agreements with the building manager
of the Project or other parties designated by Landlord for the furnishing of any
such services required to be furnished by Landlord hereunder, in form and
content approved by Landlord, provided, however, that no such contract shall
result in Tenant having to pay in the aggregate more money on account of its
occupancy of the Premises under the terms of this Lease, and provided further,
that no such contract shall result in (i) Tenant receiving fewer services or
services of a lesser quality than it is presently entitled to receive under this
Lease or (ii) a material adverse change to the benefits for which Tenant has
bargained.

     27.  EXCULPATORY PROVISIONS.  It is expressly understood and agreed by and
between the parties hereto, anything herein to the contrary notwithstanding,
that each and all of the representations, warranties, covenants, undertakings
and agreements herein made on the part of any Landlord while in form purporting
to be the representations, warranties, covenants, undertakings and agreements of
such Landlord are nevertheless each and every one of them made and intended, not
as personal representations, warranties, covenants, undertakings and agreements
by such Landlord, or for the purpose or with the intention of binding such
Landlord personally, but are made and intended for the purpose only of
subjecting such Landlord's interest in the Premises and the Project to the terms
of this Lease and for no other purpose whatsoever, and in case of default
hereunder by such Landlord (or default through, under or by any of the
beneficiaries of any Landlord which is a land trust, or any of the agents,
servants, employees or representatives of such Landlord or said beneficiaries),
Tenant shall look solely to the interests of such Landlord in the Premises and
the Project; that no Landlord nor any of the beneficiaries of any Landlord which
is a land trust shall have any personal liability to pay any indebtedness
accruing hereunder or to perform any covenant, either express or implied, herein
contained and no liability or duty shall rest upon any Landlord which is a land
trust to sequester the trust estate or the rents, issues and profits arising
therefrom, or the proceeds arising from any sale or other disposition thereof;
that no personal liability or personal responsibility of any sort is assumed by,
nor shall at any time be asserted or enforceable against, any Landlord, or
against any of the beneficiaries of any Landlord which is a land trust, on
account of this Lease or on account of any representation, warranty, covenant,
undertaking or agreement of Landlord in this Lease contained, either express or
implied, all such personal liability, if any being expressly waived and released
by Tenant and by all persons claiming by, through or under Tenant; that this
Lease, if executed by any Landlord which is a land trust, is executed and
delivered solely in the exercise of the powers conferred upon it as such
Trustee; and that as to any partnership which is a Landlord or the beneficiary
of a Landlord which is a land trust, a

     28.  EXTENSION OPTION.  Subject to Section 28c below, the Term of this
          ----------------
Lease may be extended, at the option of Tenant, for two (2) successive periods
of five (5) years each, each such period is sometimes called a "Renewal Term",
                                                                ------------
and the first such five (5) year period (if any) is sometimes called the "First
Renewal Term" and the second such five (5) year period (if any) is sometimes
called the "Second Renewal Term".  Each Renewal Term shall be upon the same
terms, covenants and conditions contained in this Lease, excluding the
provisions of Sections 28, 30, 31 and Appendix D of this Lease and except for
the payment of Base Rent during the Renewal Term; and any reference in the Lease
to the "Term" of the Lease shall be deemed to include any Renewal Term and apply
thereto unless it is expressly provided otherwise.  Tenant shall have no
extension options beyond the aforesaid two consecutive five year extension
options.  Any termination of this Lease during the initial Term of this Lease,
or during a Renewal Term shall terminate all rights under this section 28.

     A.   The Base Rent during a Renewal Term for any spaces then constituting a
portion of the Premises shall be at a rate equal to the greater of (i) the Base
Rent existing on the date Tenant delivers its initial non-binding notice, and
(ii) the Market Rate (defined hereinafter) for such space.  For purposes of this
Lease, "Market Rate" shall mean the fair net rental per annum (which shall be
        -----------
net of all taxes and operating expenses) for a period commending when the fair
net rental being determined would first be payable, assuming no rent abatements
of any kind, per rentable square foot for comparable space for a term equal to
the number of years remaining in the Term (including any Renewal Term with
respect to which Tenant has delivered its final binding written notice pursuant
to Section 28C), for a new tenant.  The calculation of Market Rate shall take
into account (and the fair net rental shall be decreased by) the present value
of any then market brokers' commission and of any then market tenant
improvement, free rent other concession which would be available to a new
tenant, and shall also take into account (and the fair net rental shall be
increased by) the present value of the cost of any actual brokers' commission or
actual tenant improvement or other concession agreed by the Landlord and Tenant
to be payable or to be granted to Tenant in connection with the particular
option with respect to which Tenant has given an initial non-binding notice. 
The calculation of Market Rate shall also take into account that Tenant pays
Tenant's Proportionate Share of the Operating Costs































<PAGE>
                                      -36B-


and Taxes in each fiscal year.  The calculation of Market Rate shall be made by
reference to comparable space in the Building, primarily, and in other buildings
within a two-mile radius of the Building which are comparable to the Building in
age and quality, secondarily, but excluding those leases where Tenant has an
equity interest in the property.

     B.   For purposes of this Lease, "Market Rate", as defined above, shall be
determined as follows:

          (i)  On or before five (5) days after the time at which Tenant must
     provide the Landlord with initial non-binding written notice under this
     Lease of its intent to exercise any of its rights to extend the Term of
     this Lease under this Section 28 or, on or before five (5) days after
     either Landlord or Tenant requests in writing a determination of Market
     Rate, which determination is required for purposes of enforcing any
     provision of this Lease, Landlord and Tenant shall commence negotiations to
     agree upon the Market Rate (to be multiplied by the rentable square feet in
     the Premises) applicable thereto.  If the Landlord and Tenant are unable to
     reach agreement on the Market Rate within twenty-one (21) days after the
     date negotiations commenced, then the Market Rate shall be determined in
     accordance with Section 28B(ii) below.

          (ii)  If the Landlord and Tenant are unable to reach agreement on the
     Market Rate within said twenty-one (21) day period, then within seven (7)
     days, the Landlord and Tenant shall each simultaneously submit to other in
     a sealed envelope its good faith estimate of the Market Rate.  If the
     higher of such estimates is not more than one hundred ten percent (110%) of
     the lower of such estimates then the Market Rate shall be the average of
     the two estimates.  Otherwise, within five (5) days either the Landlord or
     Tenant may submit the question to arbitration in accordance with Section
     28B (iii) below.

          (iii) If the Landlord and Tenant are unable to agree upon the Market
     Rate by exchange of estimates, then either may, by written notice of the
     other within five (5) days after the exchange of good faith estimate
     pursuant to Section 28B(ii) above, request to resolve the dispute by
     arbitration.  Within seven (7) days after the receipt of such request, the
     parties shall select, as an arbitrator, a mutually acceptable independent
     MAI appraiser with 




























<PAGE>

                                      -36C-

     experience in real estate activities, including at least five (5) years
     experience in appraising office space in the North Suburban Chicago area (a
     "Qualified Appraiser").  If the parties cannot agree on a Qualified
      -------------------
     Appraiser, then within a second period of seven (7) days, each shall elect
     a Qualified Appraiser and within ten (10) days thereafter the two appointed
     Qualified Appraisers shall select a third Qualified Appraiser and the third
     Qualified Appraiser shall be the arbitrator and shall determine the Market
     Rate.  If one party shall fail to make such appointment within said second
     seven (7) day period, then the Qualified Appraiser chosen by the other
     party shall be the sole arbitrator.

          (iv)  Once the arbitrator has been selected as provided in Section
     28B(iii) above, then, as soon thereafter as practicable but in any case
     within twenty-one (21) days, the arbitrator shall select one of the two
     estimates of Market Rate submitted by the Landlord and Tenant pursuant to
     Section 29B(ii), which shall be the one that is closer to the fair market
     net rental value as determined by the arbitrator.  The value so selected
     shall be the Market Rate.  The decision of the arbitrator as to the Market
     Rate shall be submitted in writing to, and the final and binding on, the
     Landlord and Tenant.  If the arbitrator believes that expert advice would
     materially assist him, he may retain one or more qualified persons,
     including but not limited to, legal counsel, brokers, architects or
     engineers, to provide such expert advice.  The party whose estimate is not
     chosen by the arbitrator shall pay the costs of the arbitrator and of any
     experts retained by the arbitrator.  Any fees of any counsel or expert
     engaged directly by the Landlord or Tenant, however, shall be borne by the
     party obtaining such counsel or expert.

          (v)  The Landlord and Tenant may, by agreement, submit any other
     number or amount in dispute under the Lease to determination by means of
     the arbitration procedure set forth in this section 28B.

     C.   Each option to extend shall be exercised by Tenant delivering an
initial non-binding written notice to Landlord not less than thirteen (13) full
calendar months prior to the expiration of the initial Term of this Lease, or 
the first Renewal Term, as the case may be.  Thereafter, the Market Rate for the
particular Renewal Term shall be calculated pursuant to Section 28B.  Such
calculation shall reflect the Market Rate that would be payable per annum for a
term commencing on the first day of the particular Renewal Term with respect to
which the calculation is being made, provided that such calculations shall


























<PAGE>

                                      -36D-


be final and shall not be recalculated at the actual commencement of such
Renewal Term (if any).  Tenant shall give Landlord final binding written notice
of intent to exercise an option to extend no later than six (6) months prior to
the expiration of the initial Term of the First Renewal Term of this Lease, as
the case may be.

     D.   Tenant's right to exercise a particular option to extend this Lease
pursuant to this Section 28, is subject to the following condition:  that on the
date that Tenant delivers its written notice of its election to exercise an
option to extend, Tenant is not in default under this Lease after having been
given notice and an opportunity to cure within the applicable cure period.

     E.   If Tenant fails to give its initial non-binding written notice of
intent or its final binding written notice of intent to exercise an option to
extend when due as provided in this Section 28, Tenant will be deemed to have
waived such option to extend.

     29.  PARKING.  Landlord shall provide Tenant with eight reserved parking
          -------
spaces in the parking lot adjacent to the Building.  Such parking spaces shall
be provided at no additional cost to Tenant.

     30.  RIGHT OF FIRST OFFER.  Subject to Section 30B below, and subject to
          --------------------
any expansion, renewal, right of first offer, or right of first refusal options
or other agreements pertaining to use or occupancy of any current tenant or
tenants in the Building (individually, the "Prior Tenant"), during the Term of
                                            ------------
this Lease, Tenant shall have and is hereby granted a right of first offer with
respect to the entire 3rd, 4th and 6th floors of the Building or any portion
thereof, (collectively the "ROFO Space"), which right shall be exercised in
                            ----------
accordance with the procedures set forth in Section 30A below.  Notwithstanding
the foregoing, with respect to all of the Expansion Space (defined in Section
34), such right of first offer shall be preempted by the Expansion Option
provided for in Section 34 and shall not be granted on any of the Availability
Dates (as set forth in Section 34), but shall subsequently be granted in the
event any Expansion Space is subsequently relet to a third party (such third
party shall be deemed a Prior Tenant for purposes of this Section 30)










<PAGE>

                                      -36E-


and such third party's lease (including any renewal or other options) expires
prior to the expiration of Tenant's Term of this Lease.

     A.   If at any time during the Term of this Lease any ROFO Space becomes
available for lease to anyone other than a Prior Tenant, Landlord shall give
written notice thereof to Tenant (the "Landlord's ROFO Notice") identifying that
                                       ----------------------
portion of the ROFO Space that is available (the "Subject ROFO Space"). 
                                                  ------------------
Landlord's ROFO Notice may be given at any time up to eight (8) months in
advance of such availability and shall contain the terms  upon which Landlord
intends to offer the Subject ROFO Space for lease to the market.  Tenant shall
notify Landlord within thirty (30) days of receipt of Landlord's ROFO Notice
whether it  desires to lease the Subject ROFO Space on the terms set forth in
Landlord's ROFO Notice; provided, however, the failure to notify Landlord within
said 30-day period shall be deemed a refusal by Tenant.  After any such refusal
or deemed refusal, Tenant shall have no further rights to such Subject ROFO
Space and Landlord shall be free to lease such space to any person or entity for
any term.  If Tenant exercises its right of first offer with respect to such
Subject ROFO Space, such space shall be added to the Premises for the remaining
Term of the Lease (including the Renewal Term, if any) on (a) all the terms,
covenants and conditions specified in the Landlord's ROFO Notice, and (b) the
terms, covenants and conditions of this Lease to the extent that such terms,
covenants and conditions of this Lease do not conflict with the terms, covenants
and conditions specified in the Landlord's ROFO Notice; provided, however, that
notwithstanding anything herein to the contrary, during the Renewal Term, if
any, Base Rent, Operating Cost Share Rent, Tax Share Rent and Additional Rent
and all other economic terms applicable to any ROFO Space shall be adjusted in
the manner provided in Section 28 hereof, and the rent and other economic terms
described in the Landlord's ROFO Notice shall not apply during any such Renewal
Term, but shall be in accordance with Section 28 above.  Any ROFO Space added to
the Premises pursuant to this Section 30 shall become a part of the Premises for
all purposes of this Lease, and any reference in this Lease to the term
"Premises" shall be deemed to refer to and include such portion of the ROFO
Space, except as expressly provided otherwise in this lease.

     B.   Tenant's right to exercise its right of first offer with respect to
any portion of the ROFO Space pursuant to this Section 30, is subject to the
following condition: that on the date that Tenant delivers its binding written
notice of its election to exercise its right of first offer, Tenant is not in
default under any of the terms, covenants or conditions of the 



























<PAGE>

                                      -36F-


Lease after having been given notice and an opportunity to cure within the
applicable cure period.

     C.   Promptly after Tenant's exercise of its right of first offer pursuant
to this Section 30, Landlord shall prepare an amendment to the Lease to reflect
changes in the size of the Premises, Base Rent, Tenant's Proportionate Share and
any other appropriate terms, due to the addition of the ROFO Space.  Landlord 
and Tenant shall execute and return such an amendment to the Lease within 
fifteen (15) days after its submission to Tenant.

     31.  TENANT CONSTRUCTION ALLOWANCE.  Landlord hereby agrees to provide
          -----------------------------
Tenant with an amount equal to Thirty-Five Thousand and NO/100 Dollars ($35,000)
(the "Tenant Construction Allowance") to be applied to the cost of the 
      -----------------------------
Build-Out (defined herein as defined in Appendix D) to be performed by Tenant. 
If the total cost incurred by Tenant in connection with that portion of the 
Build-Out approved by Landlord and Tenant as of the Commencement Date is less
than the Tenant Construction Allowance (the "Excess Construction Allowance"),
                                             -----------------------------
Landlord hereby agrees that, at Tenant's option, Excess Construction Allowance 
may be used as a credit against the first installments of Base Rent falling due
during the Term of the Lease.  If the total costs incurred by Tenant in 
connection with the Build-Out exceed the Tenant Construction Allowance, Tenant 
hereby agrees to pay the excess costs.

     32.  BUILDING NAME.  Landlord hereby agrees that Tenant may have the
          -------------
Building names after Tenant, subject to Landlord's reasonable approval of the
precise name and signage, provided that Tenant (i) is leasing at 38,050 rentable

all relevant governmental, zoning and regulatory bodies (including, without
limitation, the Village of Northbrook) to do so, and provided further that
Landlord shall have no obligation to take any action in connection therewith or
to participate in any proceedings, applications or requests.

     33.  SIGNAGE.  The parties hereby acknowledge that there is existing
          -------
exterior signage on a monument located on the east side of the Project. 
Provided that Tenant shall not have sublet all or any portion of its Premises or
assigned this Lease, upon full execution of this Lease by both parties, Tenant
shall have the right to put its signage on the existing monument, and the cost
of such sign and the installation thereof shall be paid by Landlord.  The
materials, size, shape, character, content and 




























<PAGE>

method of installation of such signage shall be subject to Landlord's prior
written approval, which approval will not be unreasonably withheld.  Upon
termination of this Lease, by lapse of time or otherwise, Tenant shall, at its
own cost, remove such signage and restore the monument to the condition that
existed prior to Tenant erecting its signage thereon pursuant to this Section
33.  Landlord and Tenant hereby agree that there shall be no monthly charge for
the rights granted to Tenant pursuant to this Section 33.

     34.  EXPANSION OPTIONS.  Subject to Section 34C below, Tenant shall have
          -----------------
and is hereby granted the options described in Section 34A below to add the
Premises the Expansion Space (hereinafter defined) for the remaining Term of

conditions contained in this Lease except Sections 29 and 31 of this Lease,
except for the abatement of Operating Cost Share Rent and Tax Share Rent
provided in Sections 2A(2) and 2A(3) which shall not be applicable to the
Expansion Space (with Tenant paying the full amount of Operating Cost Share Rent
and Tax Share Rent payable from time to time under this Lease with respect to
Expansion Space), and except for the payment of Base Rent (which shall be
payable in the amounts described hereinbelow); and provided that any space added
to the Premises pursuant to this Section 34 shall be delivered as is, and
Landlord shall have no obligation to contribute to the cost of any construction
or remodeling by Tenant, nor shall any work allowance be applicable to any such
space, nor shall Landlord be obligated to perform any construction in connection
with such space.  Tenant's obligations to pay Operating Cost Share Rent, Tax
Share Rent and Base Rent for any particular Expansion Space shall commence on
the date such space is actually made available to Tenant to be added to the
Premises.  In the event that Tenant exercises its expansion option pursuant to
this Section 34A, the Expansion Space thereby added to the  Premises shall
become a part of the Premises for all purposes of this Lease, and any reference
in this Lease to the term "Premises" shall be deemed to refer to and include any
such Expansion Space, except as expressly provided otherwise in this Lease.

                            SECOND AMENDMENT TO LEASE
                            -------------------------

     THIS SECOND AMENDMENT TO LEASE (this "Amendment") is made and entered into
as of this 24th day of April, 1995, by and between TEACHERS INSURANCE AND 
ANNUITY ASSOCIATION OF AMERICA (successor-in-interest to Teachers Realty 
Corporation), a New York corporation ("Landlord") and MEDICON, INC., an Illinois
corporation ("Tenant").

                                    RECITALS:
                                    --------

     A.  Tenant is currently occupying space in the building commonly known as
"Boulevard 40" situated at 40 Skokie Boulevard in Northbrook, Illinois (the
"Building") pursuant to that certain lease by and between Landlord and Tenant
commencing September 1, 1992, as amended by a First Amendment to Lease dated as
of August 11, 1993 (such lease as heretofore modified or amended from time to
time hereafter is called the "Lease"). Pursuant to the Lease, Landlord leased 
to Tenant certain premises (the "Premises") on the third (3rd), fourth (4th), 
fifth (5th), and sixth (6th) floors of the Building, as more particularly set 
forth in the Lease.

     B.  Landlord and Tenant desires to lease certain additional space on the
fourth (4th) floor of the Building, comprising approximately 2,572 rentable
square feet and commonly known as Suite 445 ("Suite 445") as more particularly
depicted on the space plan attached hereto as Exhibit A.
                                              ---------

     C.  Landlord and Tenant desire to amend the Lease according to the terms
hereof in order to document the leasing of Suite 445.

     NOW THEREFORE, for and in consideration of the mutual covenants contained
herein, and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

     1.   Controlling Language.  Insofar as the specific terms and provisions
          --------------------
and exhibits of this Amendment purport to amend or modify or are in conflict
with the specific terms, provisions and exhibits of the Lease, the terms,
provisions and exhibits of this Amendment shall govern and control; in all 
other respects, the terms provisions and exhibits of the Lease shall remain 
unmodified and in full force and effect.

     2.  Suite 445 Term.  Landlord leases to Tenant, and Tenant leases from
         --------------
Landlord, Suite 445 for a term (the "Suite 445 Term") commencing upon the 
Suite 445 Commencement Date and ending on August 31, 1996. The 
"Suite 445 Commencement Date" shall be the date which is thirty (30) calendar 
days after Landlord has tendered Suite 445 to Tenant in broom-clean condition. 
Except to the extent expressly modified by this Amendment, and except for
Sections 28,











































<PAGE>





31 and 34 and Appendix D of the Lease, the leasing of Suite 445 shall be subject
to all the terms and conditions of the Lease, and from and after the date
hereof, Suite 445 shall constitute a part of the "Premises," as such term is
defined in the Lease, for all purposes thereof.

     3.  Suite 445 Rent.  In addition to the rent otherwise reserved and payable
         --------------
under the Lease, Tenant agrees to pay the following with respect to Suite 445
throughout the Suite 445 Term:

          a.  Base Rent.  Base Rent in the amount of $2,036.17 per month ($9.50
              ---------
     x 2,572 rentable square feet/12).  If the Suite 445 Commencement Date is
     other than the first day of a month, the Base Rent for the month in which
     the Suite 445 Commencement Date occurs shall be adjusted on a pro rata
     basis.  The payment of Base Rent shall otherwise occur in the manner set
     forth in the Lease.

          b.  Operating Cost Share Rent and Tax Share Rent; Tenant's Suite 445
              ----------------------------------------------------------------
     Expansion Space Proportionate Share.  The term "Tenant's Suite 445
     -----------------------------------
     Proportionate Share" shall mean 2.4282% (2,572 rentable square feet in
     Suite 445 over 105,924 rentable square feet in the Building).  Tenant shall
     pay Operating Cost Share Rent and Tax Share Rent based on the Tenant's
     Suite 445 Proportionate Share, but otherwise in the manner set forth in the
     Lease. 

          c.  Additional Rent.  Additional rent shall be payable in the manner
              ---------------
     set forth in the Lease.

          d.  Abatement of Rent.  Notwithstanding the foregoing, no base or
              -----------------
     additional rent shall be payable with respect to Suite 445 until the Suite
     445 Commencement Date.

     4.  Condition of Suite 445 Expansion Space.  Suite 445 will be tendered to
         ---------------------------------------
Tenant in broom-clean condition upon the Suite 445 Commencement Date, but in all
other respects Landlord is leasing Suite 445 to Tenant "AS IS", without any
representations or warranties of any kind (including, without limitation, any
express or implied warranties of merchantability, fitness or habitability) and
without any obligation on the part of Landlord to alter, remodel, improve,
repair or decorate Suite 445 or any part thereof.  Tenant may alter or improve
Suite 445 at its cost and expense in accordance with the provisions of Section 5
of the Lease.

     5.  Condition Precedent to Effectiveness.  This amendment shall not be
         ------------------------------------
effective unless and until the current tenant of Suite 445 agrees to vacate and
actually vacates that space, and the space is tendered to Tenant as set forth in
paragraph 4 above.

          2.  Duties and Authority.

               4.2  Bonuses.
                    -------

                    4.2.1  Short-Term Incentive Bonuses.  The Executive is
                           ----------------------------
eligible to receive one of two potential cash bonuses based on the following
(which are in addition to the Annual Bonus described in Section 4.2.2 below):

                    (a)  If the Company (1) achieves positive quarterly net
income in either the first or second quarter of fiscal 1996 and (2) does not
                                                            ---
require additional capital before December 31, 1996 (excluding an initial public
offering ("IPO") or Board-approved investment by a non-affiliated corporate
partner) beyond the pending $7.5 million contribution of capital by the
principal selling shareholders of the 1994 recapitalization (the "Principals'
Contribution"), the Executive will receive a short-term incentive bonus ("Short-
Term Bonus Option One") equal to 100% of his Base Salary.  Such bonus will be
payable at the end of the fiscal year, but only if the Company has remained
profitable for the balance of the year.

                    (b)  If the Company does not satisfy 4.2.1(a) above but
instead (1) achieves positive quarterly net income in either the third or fourth
quarter of fiscal 1996 and (2) does not require additional capital before
                       ---
December 31, 1996 (excluding an IPO or Board-approved investment by a non-
affiliated corporate partner) beyond the Principals' Contribution, the Executive
will receive a short-term incentive bonus ("Short-term Bonus Option Two") equal
to 50% of his Base Salary.  Such bonus will be payable at the end of the fiscal
year, but only if the Company has remained profitable for the balance of the
year.

                    4.2.2  Annual Bonus.  For fiscal year ending December 31,
                           ------------
1996 and each fiscal year thereafter ending during the Employment Period, the
Employee will be eligible for a performance based annual bonus (the "Annual
Bonus," and together with Short-Term Bonus Option One and Short-Term Bonus
Option Two, the "Bonuses").  The Executive and the Compensation Committee will
meet during the fourth quarter of each fiscal year (beginning in the fourth
quarter of 1995) to agree upon and set appropriate performance targets for the
following year based on revenue growth, profitability per share and capital
required (the "Plan Targets").  These Plan Targets will be linked to the
Company's annual plan as approved by the Board (the "Annual Plan").  At the end
of each fiscal year the Executive's Annual Bonus payment will be as follows:

                    (a)  If the Company achieves the applicable Plan Targets, 
the Executive will receive an Annual Bonus equal to 50% of his Base Salary.

               (b)  If the Company exceeds the applicable Plan Targets, the
Executive's Annual Bonus payment may be increased up to an amount which equals
100% of his Base Salary according to a sliding scale based on extraordinary
performance.  This sliding scale will be determined each year by the
Compensation Committee based on the specific Annual Plan and Plan Targets for
that year, with the payment of an Annual Bonus equal to 100% Of Base Salary
occurring with achievement of extraordinary performance.

          The parties acknowledge that the Annual Bonus plan may have to be
revised in the event of an IPO.

          4.3  Benefits.
               --------

               4.3.1  Group Benefits.  Except as provided in the following
                      --------------

Period all health programs (including, without limitation, medical and dental
programs), 401-K programs, similar benefit plans, and other so-called "fringe

programs until the first fiscal quarter following the one-year  anniversary of
the Effective Date.  The Company agrees that each of the Fringe Benefits in
effect on the date hereof or at any time during the Employment Period shall not
be terminated, modified or replaced in any manner that materially reduces the
benefits to the Executive without the written consent of the Executive, unless
such termination or modification relates to a Fringe Benefit that is available
generally to employees of the Company or to executive employees of the Company
and such termination or modification affects all employees covered by such
Fringe Benefit.

               4.3.2  Relocation Expenses.

purchase the Executive's current residence, located at 8519 Eagle Ridge Road,
Springboro, Ohio 450066 (the "Current Residence"), at a price (the "Appraisal

any Confidential Information without the prior written consent of the Company,

Company and its subsidiaries.  Therefore, the Executive agrees that, during

following the termination of his employment with the Company, or five years if 
the Company terminates the Executive for Cause or if the Executive resigns, he 
shall not directly or indirectly own, manage, control, participate in, consult

of radiology providers or utilization review services) or are in process on the
date of the termination of the Executive's employment, within the United States.
Nothing herein shall prohibit the Executive from being a passive owner of not
more than 2.5% of the outstanding stock of any class of a corporation which is
publicly traded, so long as the Executive has no active participation in the
business of such corporation.

          ENCUMBRANCE OR OTHER DISPOSITION (EACH A "TRANSFER") AND
          VOTING OF ANY OF THE SECURITIES REPRESENTED BY THIS

attorney-in-fact, with full power of substitution of the Holder for the sole

all conveyances, assignments and transfers of the Restricted Shares, and the
Holder hereby

by virtue hereof, provided that the foregoing shall be solely for the purpose of
carrying out the provisions of this Agreement.  Nevertheless, the Holder shall,
if so requested by the Company, execute and deliver to the Company all such
instruments as may, in the reasonable judgment of the Company, be advisable for
the purpose hereof.

outstanding shares of Common Stock for all corporate purposes.  From and after
the date of original issuance, the Holder will have the right to vote the

that, until the Restricted Shares shall have become vested pursuant to the terms
hereof (i) the Holder will not be entitled to delivery of the stock certificate 
or certificates representing the Restricted Shares; (ii) the Company will retain
custody of the Restricted Shares; (iii) the Holder may, except as provided in 
Section 2.2 of the Stockholders' Agreement, dated as of November 3, 1994, and 
amended as of September 6, 1995, among the Company and the Stockholders named 
therein (the "Stockholders' Agreement") not sell, assign, transfer, pledge, 
exchange, encumber or dispose of the Restricted Shares.  A material breach of 
any of the foregoing restrictions or a material breach of any of the other 
restrictions, terms and conditions of this Agreement with respect to any of the 
Restricted Shares, except as waived by the Company, will cause a forfeiture of 
such Restricted Shares; and (iv) the Company will retain custody of all 
distributions ("Retained Distributions") made or declared with respect to the 
Restricted Shares (and such Retained Distributions will be subject to the same 
restrictions, terms and conditions as are applicable to the Restricted Shares)

Retained Distributions shall have been made, paid or declared shall have become 
vested, and such Retained Distributions shall not bear interest or be segregated
in separate accounts.

          5.  No Right to Employment.  Nothing in this Agreement shall be
              ----------------------
construed to give the Holder any right to be awarded any additional Restricted
Shares or to confer on the Holder any right to continue in the employ of the
Employer or to be evidence of any agreement or understanding, express or
implied, that the Company or any of its subsidiaries will employ the Holder in
any particular position or at any particular rate of remuneration, or for any
particular period of time or to interfere in any way with the right of the

          AGREEMENT made and entered into as of February 15, 1996, by and
between MEDICON, INC., an Illinois corporation (the "Company"), and JACK M.

                              W I T N E S S E T H:
                              - - - - - - - - - -

          WHEREAS, the Company previously employed the Optionee as an employee
of the Company; and

          WHEREAS, the Company and the Optionee entered into a Severance
Agreement, dated the date hereof, pursuant to which, among other things, the
Company and the Optionee agreed to terminate any options previously granted to
the Optionee in exchange for the options newly issued hereunder; and

          NOW, THEREFORE, in consideration of the foregoing promises and of the
mutual covenants and agreements herein contained, the parties hereby agree as
follows:

          1.  Grant of Option.  Subject to the terms and conditions set forth
              ---------------
herein, the Company grants to the Optionee an option (the "Option") to purchase
from the Company all or any part of an aggregate of 35,000 shares (the "Optioned
Shares") of Class A Common Stock, no par value (the "Common Stock").

          2.  Cancellation of Old Options.  As a condition to the granting of
              ---------------------------
this Option, the Optionee hereby consents to the cancellation and surrender of
the options previously granted to him and referred to in the second Whereas
clause above.

          3.  Exercise Price.  The purchase price for the Optioned Shares shall
              --------------
be $0.01 per share (the "Option Price").

          4.  Term of Option.  This Option shall be vested immediately and shall
              --------------
be exercisable, either in whole or in part, at any time after the date of this
Agreement, but in any event prior to February 15, 1999 (the "Expiration Date").

          5.  Method of Option Exercise.  The Option or any part thereof may be
              -------------------------
exercised only by giving to the Company written notice of exercise addressed and
delivered to the Company (Attention:  Chief Financial Officer) specifying the
number of shares of Common Stock to be purchased.  Full



<PAGE>
                                                                               2


payment of the purchase price shall be made on the option exercise date by
certified or official bank check or, in the Company's discretion, by personal
check (subject to collection), payable to the Company, by delivery of shares of
Common Stock already owned by the Optionee, or by a combination thereof.  The
Optionee shall have no right to pay the option exercise price, or to receive
shares of Common Stock with respect to an Option exercise, prior to the option
exercise date.  For purposes of this option agreement, the "option exercise
date" shall be deemed to be the first business day immediately following the
date written notice of exercise is received by the Company.

          6.  Termination.  This Option may not be exercised after the
              -----------
Expiration Date.

          7.  Shares for Investment.  The certificate representing the shares of
              ---------------------
Common Stock purchased upon exercise of any Option shall be issued as of the
exercise date and delivered by the Company to the Optionee free and clear of all
claims, liens and encumbrances, within five days following the exercise date or
as soon thereafter as practicable.  As a condition to the exercise of any
Option, the Company may require the Optionee to represent and warrant at the
time of any such exercise that the shares of Common Stock are being purchased
for investment purposes only, for the account of the Optionee and without any
intention to distribute such shares.  If the shares of Common Stock issuable
upon exercise of any Option have not previously been registered under the
Securities Act of 1933, as amended, each certificate evidencing shares of Common
Stock acquired upon exercise of the Option shall contain on its face, or on the
reverse side thereof, in addition to any other legends required pursuant to
applicable law or contractual agreements between the Company and the Optionee,
the following legend:

     "These shares have not been registered under the Securities Act of 1933 or
     under any applicable state law.  They may not be offered for sale, sold,
     transferred, or pledged without (1) registration under the Securities Act
     of 1933 and any applicable state law, or (2) an opinion (satisfactory to
     the corporation) that registration is not required."

          8.  Adjustment Upon Changes in Capitalization.  Subject to the
              -----------------------------------------
following provisions of this Section, in the event of any change in the number
of issued shares of Common Stock resulting from the subdivision or combination
of shares of Common Stock or other capital adjustment or the payment of a stock
dividend after the effective date of this Agreement, or other change in such
shares of Common Stock effective without receipt of consideration by the
Company, an appropriate and proportionate adjustment shall be made in

                                                                               3


the number of shares of Common Stock subject to the Option and the exercise
price of the Option granted under this Agreement and the amount payable by an
Optionee in respect of an Option.  Adjustments under this Section shall be made
by the Board of Directors or a Committee thereof whose determination as to what
adjustment shall be made, and the extent thereof, shall be final, binding and
conclusive.

          9.  Withholding Obligations.  In the event that the Company is
              -----------------------
required to satisfy withholding obligations under the Internal Revenue Code as a
result of the exercise of any Option, the Optionee may request that, in lieu of
requiring that the Optionee deliver a check in the amount of the withholding
obligation, the Company withhold that number of shares of Common Stock which
have a fair market value on the exercise date equal to the amount required to be
withheld.

          10.  Nontransferability.  All Options contained herein are not
               ------------------
transferable or assignable by the Optionee other than by will or by the laws of
descent and distribution and are exercisable during the lifetime of the Optionee
only by the Optionee.

          11.  Execution of Agreement.  Notwithstanding anything contained in
               ----------------------
this Agreement to the contrary, no option may be exercised until the Optionee
has returned an executed copy of this option agreement to the Company.

          12.  Compliance with Law.  By accepting any Option, the Optionee
               -------------------
agrees for Optionee and Optionee's legal representative that the Company shall
not be required to deliver any shares of Common Stock upon the exercise of any
Option until such shares have been qualified for delivery under applicable
securities laws and regulations as determined by the Company or its legal
counsel.  The Company will comply with applicable securities laws and
regulations to effectuate the terms of this provision.

          13.  Rights as a Stockholder.  The Optionee shall have no rights as a
               -----------------------
stockholder of the Company with respect to shares of Common Stock subject to the
Option until the Option has been exercised and payment made as herein provided
and certificates representing the shares as to which the Option has been
exercised have been delivered to the Optionee.

          14.  Notices.  Any notice to be given to the Company hereunder shall
               -------

hold for the benefit of the Company as Pledged Collateral and shall, if received
by the Pledgor, be received in trust for the benefit of the Company, be
segregated from the other property or funds of the Pledgor, and be delivered
immediately to the Company as Pledged Collateral in the same form as so received
(with any necessary endorsement); and

                    (ii)  The Company shall execute and deliver (or cause to be
executed and delivered) to the Pledgor all such proxies and other instruments as

gor may reasonably request for the purpose of enabling the Pledgor to receive
the dividends or interest payments which  she is authorized to receive and
retain pursuant to clause (i) above.
              
               (b)  After the occurrence of any condition, event or act which
constitutes an Event of Default or which with notice or lapse of time or both
would constitute an Event of Default:

                    (i)  All rights of the Pledgor to receive the dividends

of the Pledged Collateral without the prior written consent of the Company, or
(ii) create or permit to exist any Lien upon or with respect to any of the

Agreement.  Notwithstanding the foregoing, on the Maturity date (as defined in

margin all or any of the Pledged Collateral, provided that, in the case of any
such sale, transfer or margin, the proceeds thereof (or a portion thereof equal
to the outstanding principal amount of and accrued interest on the Promissory
Note) are first applied to the payment of the indebtedness of the Pledgor under
the Promissory Note.

               9.  Remedies. 
                   --------
                   
                    (a) The Company shall have, in addition to any other rights
given under this Pledge Agreement or by law, all of the rights and remedies with
respect to the Pledged Collateral of a secured party under the Uniform
Commercial Code as in effect in the State of Illinois.  In addition, after the
occurrence of an Event of Default, the Company shall have such powers of sale
and other powers as may be conferred by applicable law.  With respect to the

                                                                         5


Pledged Collateral or any part thereof which shall then be in or shall
thereafter come into the possession or custody of the Company or which the
Company shall otherwise have the ability to transfer under applicable law, the
Company may, in its sole discretion, without notice except as specified below
after the occurrence of an Event of Default, sell or cause the same to be sold
at any exchange, broker's board or at public or private sale, in one or more
sales or lots, at such price as the Company may deem best, for cash or on credit
or for future delivery, without assumption of any credit risk, and the purchaser
of any or all of the Pledged Collateral so sold shall thereafter own the same,
absolutely free from any claim, encumbrance or right of any kind whatsoever. 
The Company may, in its own name, or in the name of a designee or nominee, buy
the Pledged Collateral at any public sale and, if permitted by applicable law,
buy the Pledged Collateral at any private sale. The Pledgor will pay to the
company all reasonable expenses (including, without limitation, court costs and
reasonable attorneys' and paralegals' fees and expenses) of, or incidental to,
the enforcement of any of the provisions of this Pledge Agreement.  The Pledgor
shall not be liable for any deficiency following the sale of the Pledged
Collateral, except for the costs and expenses incurred by the Company or its
agent in connection with the enforcement of its remedies under this Section 9
and to the extent provided for in the Promissory Note.

                    (b)  Unless any of the Pledged Collateral threatens to
decline speedily in value or is or becomes of a type sold on a recognized
market, the Company will give the Pledgor reasonable notice of the time and
place of any public sale thereof, or of the time after which any private sale or
other intended disposition is to be made.  Notwithstanding any provision to the
contrary contained herein, the Pledgor agrees that any requirements of
reasonable notice shall be met if such notice is received by the Pledgor as
provided in Section 23 below at least five (5) Business Days (as hereinafter
            ----------
defined) before the time of the sale or disposition; provided, however, that
                                                     --------  -------
Company may give any shorter notice that is commercially reasonable under the
circumstances.  Any other requirement of notice, demand or advertisement for
sale is waived, to the extent permitted by law.  "Business Day" means any day
other than a Saturday, Sunday or other day on which banks are authorized or
required to be closed in New York City.

                    (c)   The Pledgor recognizes that federal and state
securities laws may impose certain restrictions on the method by which a sale of
the Pledged Collateral may be effected after an Event of Default, and the
Pledgor agrees that after the occurrence of an Event of Default (i) it will be
commercially reasonable if a private sale, upon at least



<PAGE>

                                                                         6



five (5) Business Days' notice to the Pledgor, is arranged so as to avoid a
public offering, even though the sales price established and/or obtained at such
private sale may be substantially less than prices which could have been
obtained for such security on any market or exchange or in any other public sale
and (ii) the Company may, from time to time, attempt to sell  all or any part of
the Pledged Collateral by means of a private placement restricting the bidders
and prospective purchasers to those who are qualified and will represent and
agree that they are purchasing for investment only and not for distribution.  In
so doing, the Company may solicit offers to buy the Pledged Collateral, or any
part of it, from a limited number of investors deemed by the Company, in its
reasonable judgment, to be financially responsible parties who might be
interested in purchasing the Pledged Collateral.  If the Company solicits such
offers from not less than four (4) such investors, then the acceptance by the
Company of the highest offer obtained therefrom shall be deemed to be a
commercially reasonable method of disposing of such Pledged Collateral;
provided, however, that this Section does not impose a requirement that the
- --------  -------
Company solicit offers from four or more investors in order for the sale to be
commercially reasonable.

          10.   Application of Proceeds.  The proceeds of any sale, public or
                -----------------------
private, of all or any portion of the Pledged Collateral shall be applied by the
Company as follows: (i) first, to the payment of the costs and expenses
incidental to the care or safekeeping of the Pledged Collateral and incurred in
such sale, including reasonable out-of-pocket costs and expenses of the Company
and the reasonable expenses of its agents and counsel; (ii) second, to the
payment of interest on the Promissory Note; (iii) third, to the payment in full
of the principal amount owed and outstanding under the Promissory Note.  The
balance, if any, remaining after payment in full of the Promissory Note, shall
be paid to the Pledgor, subject to any duty of the Company imposed by law to the
holder of any subordinate security interest in the pledged Collateral known to
the Company.

          11.  Security Interest Absolute.  All rights of the Company and
               --------------------------
security interests hereunder, and all obligations of the Pledgor hereunder,
shall be absolute and unconditional irrespective of (i) any change in the time,
manner or place of payment of, or in any other term of, all or any part of the
Liabilities, and (ii) any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Pledgor in Respect of the
Liabilities or of this Pledge Agreement.

Agreement shall be unconditional, irrespective of (i) the validity or
enforceability, avoidance or subordination of the Liabilities; (ii) the absence
of any attempt by, or on behalf of, the Company to collect or take any other
action to enforce, all or any part of the Liabilities; (iii) the election of any
remedy by, or on behalf of, the Company with respect to all or any part of the
Liabilities; (iv) the failure of the Company to take any steps to perfect and
maintain its security interests in, or to preserve its right to any of the
Pledged Collateral for all or any part of the Liabilities; or (v) any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of the Pledgor. 

               (b)  The Pledgor hereby waives any requirement of diligence,
presentment, demand of payment, protest or notice with respect to all or any
part of the Liabilities, the benefit of any statutes of limitation, and all
demands whatsoever, and covenants that this Pledge Agreement will not be
discharged, except by complete performance of the Liabilities.

               (c)  The Pledgor consents and agrees that neither the Company nor

                              Employment Agreement
                              --------------------

This EMPLOYMENT AGREEMENT (the  "Agreement") is dated September  6, 1995 and
effective as of October 1, 1995 (the "Effective  Date"), between MEDICON, Inc.,
an Illinois corporation (the "Company"), and Alan P. Mintz (the "Employee");

WHEREAS, the Board of Directors of the Company (the "Board") approved and
authorized the entry into this Agreement with the Employee;

WHEREAS, the parties desire to enter into this Agreement setting forth the terms
and conditions for the employment relationship between the Employee and the
Company.

NOW, THEREFORE, it is AGREED as follows:

1.   Employment.  The Employee is employed as Chairman of the Board of the
     ----------
     Company from the date hereof through the term of this Agreement. In this
     capacity, the Employee shall have such duties and responsibilities as the
     Board shall designate and as are not inconsistent with the Employee's
     position with the Company, including the performance of duties with respect
     to any subsidiaries of the company.

2.   Term.
     -----

     (a)  The term of employment under this Agreement shall commence on the
          Effective Date and end as provided below in this Section 2 (the
          "Employment Period"). The Employment Period shall end on December 31,
          1996, provided that (i) the employment of the Employee shall terminate
          prior to such date (a) upon the Employee's resignation or death or (b)
          upon the permanent disability or incapacity of the Employee that
          causes the Employee to be unable to perform his duties under this
          Agreement (as  determined by the Board of Directors in its good faith
          judgement) and (ii) the Employment Period may be terminated by the
          Company at any time without Cause (as  defined below) upon 90 days'
          prior written notice or for Cause at any time. Notwithstanding the
          foregoing, this Agreement will be renewed annually under similar
          general terms unless the Board of Directors delivers notice of its
          decision not to renew such Agreement to the Employee at least 90 days
          prior to the expiration of the then-applicable term of employment.

     (b)  If Employment period is terminated by the Company without Cause, the
          Employee shall be entitled to receive a severance payment equal to one
          year of Base Salary (as defined below) paid out monthly; provided,
          however, that the Company will cease paying such severance if the
          Employee becomes employed within such time period; provided, further,
          that the Company shall also cease paying such severance if the
          Employee materially breaches any provision of paragraphs 8 or 9
          hereof.


                                        1










<PAGE>







     (c)  If the Employment Period is terminated by the Company for Cause or is
          terminated pursuant to clause (a)(i) above, the Employee shall be
          entitled to receive his Base Salary through the date of termination.

     (d)  All of the Employee's rights to Fringe Benefits (as defined below) and
          Bonuses (as defined below) hereunder (if any) accruing after the
          termination of the Employment Period shall cease upon such
          termination.

     (e)  For purposes of this Agreement, "Cause" shall mean (i) the commission
          of a felony or a crime involving moral turpitude or the commission of
          any other act involving dishonesty, disloyalty or fraud with respect
          to the Company or any of its subsidiaries, (ii) conduct tending to
          bring the Company or any of its subsidiaries into substantial public
          disgrace or disrepute, (iii) failure to perform duties as reasonably
          and lawfully directed by the Board of Directors, (iv) gross negligence
          or willful misconduct with respect to the Company or any of its
          subsidiaries or (v) any other material breach of this Agreement which
          is not cured within 15 days after written notice thereof to the
          Employee, in each case as determined in the good faith judgment of
          the Board of Directors.

3.   Salary.  The Company agrees to pay the Employee during the term of this
     ------
     Agreement a salary at an annual rate of $250,000 (the "Base Salary"),
     payable in accordance with the payroll policy of the Company (but not less
     frequently than monthly), less such deductions or amounts to be withheld as
     shall be required by applicable law and regulations.  Participation in
     deferred compensation, performance bonus, retirement, and other employee
     benefit plans and in fringe benefits shall not reduce the Base Salary
     payable to the Employee under this Section 3.

4.   Performance Bonuses.
     -------------------

     (a)  Short-term Incentive Bonus.  The Employee is eligible to receive one
          --------------------------
          of two potential cash bonuses based on the following (which are in
          addition to the Annual Bonus described in Section 4(b) below):

          (i)  If the Company (1) achieves positive quarterly net income in
               either the first or second quarter of fiscal 1996 and (2) does
                                                                 ---
               not require additional capital before June 30, 1996 (excluding
               IPO or Board-approved investment by a non-affiliated corporate
               partner) beyond the pending $7.5 million contribution of capital
               by the principal selling shareholders of the 1994
               recapitalization (the "Principals' Contribution"), the Employee
               will receive a short-term incentive bonus ("Short-Term Bonus
               Option One") equal to 50% of his Base Salary.  Such bonus will
               be payable at the end of the fiscal year, but only if the Company
               has remained profitable for the balance of the year and has not
               required any additional cash investment.

          (ii) If the Company does not satisfy 4(a)(i) above but instead (1)
               achieves positive quarterly net income in either the third or
               fourth quarter of fiscal 1996 and  (2) does not require
                                             ---
               additional capital before December 31, 1996 (excluding an IPO or
               Board-



                                        2

<PAGE>
               approved investment by a non-affiliated corporate partner) beyond
               the Principals' Contribution, the Employee will receive a short-
               term incentive bonus ("Short-term Bonus Option Two") equal to 25%
               of his Base Salary.  Such bonus will be payable at the end of the
               fiscal year only if the company has remained profitable for the
               balance of the year.

     (b)  Annual Bonus.  For fiscal years ending December 31, 1996 and beyond,
          ------------

          the Employee will be eligible for a performance based annual bonus
          (the "Annual Bonus," and together with Short-Term Bonus Option One and
          Short-Term Bonus Option Two, the "Bonuses").  The Compensation
          Committee will meet during the fourth quarter of each fiscal year
          (beginning in the fourth quarter of 1995) to agree upon appropriate
          performance targets for the following year based on revenue growth,
          profitability per share and capital required (the "Plan Targets").
          These Plan Targets will be linked to the Company's annual plan as
          approved by the Board of Directors (the "Annual Plan").  At the end of
          each fiscal year the Employee's Annual Bonus payment will  be as
          follows:

          (i)  If the Company achieves the applicable Plan Targets, the employee
               will receive an Annual Bonus equal to 25% of his Base Salary.

          (ii) If the Company exceeds the applicable Plan Targets, the
               Employee's Annual Bonus payment may be increased to an amount
               which equals up to 50% of his Base Salary according to a sliding
               scale based on extraordinary performance.  This sliding scale
               will be determined each year by the Compensation Committee based
               on the specific Annual Plan and Plan Targets for that year with
               the payment of an Annual Bonus equal to 50% of Base Salary
               occurring with achievement of extraordinary performance.

                    The parties acknowledge that the Annual Bonus plan may have
                    to be revised in the event of an IPO.

5.   Participation in Retirement and Employee Benefit Plans.  The Employee shall
     ------------------------------------------------------
     be entitled to participate in or receive benefits under any plan of the
     Company relating to pension, thrift, profit sharing, life insurance,
     medical coverage, disability, education, or other retirement or employee
     benefits that are available generally to executive employees of the Company
     (collectively "Fringe Benefits")

6.   Vacations.  The Employee shall be entitled to an annual paid vacation of
     ---------
     six weeks per year.  Any vacation days unused in any calendar year will be
     lost.  The timing of paid vacations shall be scheduled in a reasonable
     manner by the Employee, with approval of the Company, said approval to not
     be unreasonably withheld.

7.   Business Expenses.  The Employee shall be entitled to prompt reimbursement
     -----------------
     for all reasonable business expenses incurred by the Employee in the
     performance of his duties.


                                       3

<PAGE>




8.   Confidential Information.     The Employee acknowledges that the
     ------------------------
     information, observations and data obtained by him while employed by the
     Company concerning the business or affairs of the Company or any of its
     subsidiaries ("Confidential Information") are the property of the Company
     or such subsidiary.  Therefore, the Employee agrees that he shall not
     disclose to any unauthorized person or use for his own account any
     Confidential Information without the prior written consent of the Board of
     Directors of the Company, unless and to the extent that the aforementioned
     matters are or become generally known to and available for use by the
     members of the industry in which the Company operates other than as a
     result of the Employee's acts or omissions to act.  The Employee shall
     deliver to the Company at the termination of the Employment Period or at
     any other time that the Company requests, all memoranda, notes, plans,
     records, reports and other documents and data (and any copies thereof)
     relating to the Confidential Information or the business of the Company or
     any of its subsidiaries which he may then possess or have under his
     control.

9.   Noncompete, Nonsolicitation.
     ---------------------------

     (a)  The Employee acknowledges that during his employment with the Company
          he has become familiar with the Company's and its subsidiaries' trade
          secrets, and with other confidential information of the Company and
          its subsidiaries and that his services have been and will be of
          special, unique and extraordinary value to the Company and its
          subsidiaries.  Therefore, the Employee agrees that during the
          Employment Period and for a period (the "Noncompete Period") of three
          years following the termination of his employment with the Company, or
          five years if the Company terminates the employment for Cause or if
          the Employee resigns, he shall not directly or indirectly own, manage,
          control, participate in, consult with, render services for, or in any
          manner engage in any business competing with the business of the
          Company or its subsidiaries as such businesses exist (including,
          without limitation, diagnostic imaging management care services,
          diagnostic imaging practice management services, building or acquiring
          networks of radiology providers or utilization review services) or are
          in process on the date of the termination of the Employee's employment
          , within the United States.

     (b)  During the Noncompete Period, the Employee shall not directly or
          indirectly through another entity (i) induce or attempt to induce any
          employee of the Company or any of its subsidiaries to leave the employ
          thereof, or in any way interfere with the relationship between the
          Company or any of its subsidiaries and any employee thereof, (ii) hire
          any person who was an employee of the Company or any of its
          subsidiaries at any time during the Employment Period, other than an
          employee whose employment with such entity was terminated by such
          entity, or (iii) induce or attempt to induce any customer,client,
          supplier, licensee, vendor, physician or other business relation of
          the Company or any of its subsidiaries to cease doing business with
          the Company or such subsidiary, or in any way interfere with the
          relationship between any such customer, supplier, licensee, vendor or
          business relation and the Company or its subsidiaries.

     (c)  If, at the time of enforcement of this paragraph 9, a court shall hold
          that the duration, scope or area restrictions stated herein are
          unreasonable under circumstances then


                                        4

          existing, the parties agree that the maximum duration, scope or area

Gentlemen:

Please accept this letter as my resignation as Chairman and as a member of the
Board of Directors of Medicon effective December 21, 1995, in order to pursue
other business and personal interests.  This decision is made with great
difficulty, as I will immediately miss my association with the Company,
investors, officers, and employees, as well as the opportunity to participate
directly in the decisions ahead as the Company continues its course of dynamic
growth.

I extend my personal best wishes for the Company's future growth and success.

Sincerely,

 /s/ Alan P. Mintz, M.D.

                             STOCK OPTION AGREEMENT
                             ----------------------

               AGREEMENT made and entered into as of February 15, 1996, by and
between MEDICON, INC., an Illinois corporation (the "Company"), and ALAN P.
MINTZ, M.D. (the "Optionee").


                              W I T N E S S E T H :
                              - - - - - - - - - - 

               WHEREAS, the Company desires to issue an option to purchase
shares of Class A Common Stock, no par value ("Common Stock"), of the Company
pursuant to the terms and conditions specified herein.

               NOW, THEREFORE, in consideration of the foregoing promises and of
the mutual covenants and agreements herein contained, the parties hereby agree
as follows:

               1. Grant of Option. Subject to the terms and conditions set forth
                  ---------------
herein, the Company grants to the Optionee an option (the "Option") to purchase
from the Company all or any part of an aggregate of 23,899 shares of Common
Stock (the "Optioned Shares").

               2. Exercise Price. The purchase price for the Optioned Shares
                  --------------
shall be $0.01 per share (the "Option Price").

               3. Term of Option. This Option shall be exercisable, either in
                  --------------
whole of in part, with respect to one-third of the Optioned Shares at any time
after August, 15, 1996, with respect to the second one-third of the Optioned
Shares at any time after August, 15, 1997 and with respect to the remaining
one-third of the Optioned Shares at any time after August 15, 1998, but in each
case prior to February 15, 1999.

               4. Method of Option Exercise. The Option or any part thereof may
                  -------------------------
be exercised only by giving to the Company written notice of exercise addressed
and delivered to the Company (Attention: Chief Financial Officer) specifying the
number of shares of Common Stock to be purchased. Full payment of the purchase
price shall be made on the option exercise date by certified or official bank
check or, in the Company's discretion, by personal check (subject to
collection), payable to the Company, by delivery of shares of Common Stock
already owned by the Optionee, or by a combination thereof. The Optionee shall
have no right to pay the


<PAGE>



option exercise price, or to receive shares of Common Stock with respect to an
Option exercise, prior to the option exercise date. For purposes of this option
agreement, the "option exercise date" shall be deemed to be the first business
day immediately following the date written notice of exercise is received by the
Company.

               5. Shares for Investment. The certificate representing the shares
                  ---------------------
of Common Stock purchased upon exercise of any Option shall be issued as of the
exercise date and delivered by the Company to the Optionee free and clear of all
claims, liens and encumbrances, within five days following the exercise date or
as soon thereafter as practicable. As a condition to the exercise of any Option,
the Company may require the Optionee to represent and warrant at the time of any
such exercise that the shares of common Stock are being purchased for investment
purposes only, for the account of the Optionee and without any intention to
distribute such shares. If the shares of Common Stock issuable upon exercise of
any Option have not previously been registered under the Securities Act of 1933,
as amended, each certificate evidencing shares of Common Stock acquired upon
exercise of the Option shall contain on its face, or on the reverse side
thereof, in addition to any other legends required pursuant to applicable law or
contractual agreements between the Company and the Optionee, the following
legend:

        "These shares have not been registered under the Securities Act of 1933
        or under any applicable state law. They may not be offered for sale, 
        sold, transferred, or pledged without (1) registration under the 
        Securities Act of 1933 and any applicable state law, or (2) an opinion 
        (satisfactory to the corporation) that registration is not required."

               6. Adjustment Upon Changes in Capitalization. Subject to the
                  -----------------------------------------
following provisions of this Section, in the event of any change in the number
of issued shares of Common Stock resulting from the subdivision or combination
of shares of Common Stock or other capital adjustment or the payment of a stock
dividend after the effective date of this Agreement, or other change in such
shares of Common Stock effective without receipt of consideration by the
Company, an appropriate and proportionate adjustment shall be made in the number
of shares of Common Stock subject to the Option and the exercise price of the
Option granted under this Agreement and the amount payable by an Optionee in
respect of an Option. Adjustments under this Section shall be made by the Board
of Directors or a Committee thereof whose determination as to what adjustment
shall be made, and the extent thereof, shall be final, binding and conclusive.


<PAGE>



               7. Withholding Obligations. In the event that the Company is
                  -----------------------
required to satisfy withholding obligations under the Internal Revenue Code as
a result of the exercise of any Option, the Optionee may request that, in lieu
of withholding amounts from the Optionee's paycheck of requiring that the
Optionee deliver a check in the amount of the withholding obligation, the
Company withhold that number of share of Common Stock which have a fair market
value on the exercise date equal to the amount required to be withheld.

               8.  Nontransferability.  All Options contained herein are not
                   ------------------
transferable or assignable by the Optionee other than by will or by the laws of
descent and distribution and are exercisable during the lifetime of the Optionee
only by the Optionee.

               9.  Execution of Agreement.  Notwithstanding anything 
                   ----------------------
contained in this Agreement to the contrary, no option may be exercised until 
the Optionee has returned an executed copy of this option agreement to the 
Company.

               10. Compliance with Law. Buy accepting any Option, the Optionee
                   -------------------
agrees for Optionee and Optionee's legal representative that the Company shall
not be required to deliver any shares of Common Stock upon the exercise of any
Option until such shares have been qualified for delivery under applicable
securities law and regulations as determined by the Company or its legal
counsel. The Company will comply with applicable securities laws and regulations
to effectuate the terms of this provision.

               11. Rights as a Stockholder. The Optionee shall have no rights as
                   -----------------------
a stockholder of the Company with respect to shares of Common Stock subject to
the Option until the Option has been exercised and payment made as herein
provided and certificates representing the shares as to which the Option has
been exercised have been delivered to the Optionee.

               12. Notices. Any notice to be given to the Company hereunder 
                   -------

                 Notwithstanding the foregoing, in the event the Optionee is
unable to exercise the Option during any of the periods described in clauses
(ii) or (iii) above due to restrictions set forth in any trading policy of the
company which is then in effect, the Option shall remain exercisable until such

not defined therein or if there shall be no such agreement, as defined in the
Company's long-term disability plan as in effect from time to time, or if there
shall be no plan or if not defined therein, the Optionee's becoming physically
or mentally incapacitated and consequent inability for a period of six (6)

                 (i) Subject to Section 3(a), the Vested Portion of the
Option may be exercised by delivering to the Company at its principal office

exercised with respect to whole Shares only.  Such notice shall specify the
number of Shares for which the Option is being exercised and shall be
accompanied by payment in full of the Exercise Price.  The payment of the
Exercise Price shall be made in cash or its equivalent, or, if and to the extent
permitted by the Company's Compensation Committee, (i) by exchanging Shares 
owned by the Optionee (which are not the subject of any pledge or other 
security interest and which have been owned by the Optionee for at least 6 
months), or (ii) through delivery of irrevocable instructions to a broker 
to deliver promptly to the Company an amount equal to the aggregate exercise 
price, or by a combination of the foregoing, provided that the combined value 
                                             --------
of all cash and cash equivalents and the fair market value of any such Shares 
so tendered to the Company as of the date of such tender is at least equal to 
the aggregate Exercise Price.

                 (ii) Notwithstanding any other provision of this Agreement
to the contrary, the Option may not be exercised prior to the completion of any
registration or qualification of the Option or the Shares under applicable state
and federal securities or other laws, or under any ruling or regulation of any
governmental body or national securities exchange that the Company's
Compensation Committee shall in its sole discretion determine to be necessary or
advisable.


                                   3

<PAGE>

                 (iii) Upon the Company's determination that the Option has
been validly exercised as to any of the Shares, the Company shall issue
certificates in the Optionee's name for such Shares.  However, the Company shall
not be liable to the Optionee for damages relating to any delays in issuing the
certificates to him, any loss of the certificates, or any mistakes or errors in
the issuance of the certificates or in the certificates themselves.

                 (iv) In the event of the Optionee's death, the Vested
Portion of the Option shall remain exercisable by the Optionee's executor or
administrator, or the person or persons to whom the Optionee's rights under this
Agreement shall pass by will or by the laws of descent and distribution as the
case may be, to the extent set forth in Section 3(a).  Any heir or legatee of

conditions hereof.

              4.   No Right to Continued Employment.  This Agreement shall
                   --------------------------------

of, or in any consulting relationship to, the Company or any Affiliate. 
Further, the Company or an affiliate may at any time dismiss the Optionee or
discontinue any consulting relationship, free from any liability or any claim
under this Agreement, except as otherwise expressly provided herein.

              5.   Legend on Certificates.  The certificates representing the
                   ----------------------
Shares purchased by exercise of the Option shall be subject to such stop
transfer orders and other restrictions as the Company's Compensation Committee
may deem advisable under the rules, regulations, and other requirements of the
Securities and Exchange Commission, any stock exchange upon which such Shares
are listed, and any applicable Federal or state laws, and the Company's
Compensation Committee may cause a legend or legends to be put on any such
certificates to make appropriate reference to such restrictions.

              6.   Transferability.  This Option is not transferable or
                   ---------------
assignable by the Optionee other than by will or by the laws of descent and
distribution and is exercisable during the lifetime of the Optionee only by the

arrangements with the Company for satisfaction of any applicable federal, state
or local income tax, withholding requirements or like requirements, including
the payment to the Company at the time of exercise of, or other settlement in
respect of, the Option of all such taxes and requirements and the Company shall
be authorized to take such action as may be necessary in the opinion of the
Company's counsel (including, without limitation, withholding Shares otherwise
deliverable to the Optionee hereunder and/or withholding amounts from any
compensation or other amount owing from the Company to the Optionee) to satisfy

written representations, warranties and agreements as the Company's Compensation
Committee may reasonably request in order to comply with applicable securities
laws or with this Agreement.

          1.  Employment.  The Employee is employed as Executive Vice President
              ----------

              ------
this  Agreement  a salary  at  an annual  rate  of $175,000.    Participation in
deferred  compensation,  discretionary  bonus,  retirement,  and  other employee
benefit plans and in fringe benefits shall not reduce the base salary payable to
the Employee under  this Section 3.   The salary under  this Section 3  shall be
payable by the Company to the Employee not less frequently than monthly.

          4.  Discretionary  Bonuses.   During the term  of this Agreement,  the
              ----------------------
Employee  shall be  entitled to  participate in  bonuses as  may be  authorized,
declared, and  paid by  the Board in  its complete  discretion to  the executive
officers of the Company.   No other compensation provided for  in this Agreement
shall be  deemed a substitute  for the Employee's  right to participate  in such
bonuses when and as declared by such Board of Directors.

          5.   Participation  in Retirement  and  Employee Benefit  Plans.   The
               ----------------------------------------------------------
Employee shall be entitled to participate in or receive benefits under  any plan
of  the Company  relating to  pension, thrift,  profit sharing,  life insurance,
medical  coverage,  disability,  education,  or  other  retirement  or  employee
benefits  that the  Company has  adopted  or may  adopt for  the benefit  of its
employees.

only be terminated  for "Cause".  Termination  by the Company of  the Employee's
employment  for "Cause" shall mean termination upon (1) the continued failure by
the Employee to substantially





<PAGE>

perform his  duties with  the Company  after  a written  demand for  substantial
performance  is  delivered  to  him  by the  Board,  which  demand  specifically
identifies the manner  in which the Board believes that he has not substantially
performed his duties or (2) the substantial violation of any of  the substantive
terms of this Agreement, dishonesty, conviction of a felony, moral turpitude, or
any act that is demonstrably and materially injurious to the Company, monetarily
or otherwise.

hereto.   No party may  assign or delegate  any rights or  obligations hereunder
without  first  obtaining the  written  consent  of  the other  parties  hereto.

payments hereunder shall become rights of the Employee's estate.

enforceable  by  the  Employee  and  his  personal  or   legal  representatives,
executors,  administrators, successors, heirs, distributees, devisees and

payable to  him hereunder had he continued to live, all such  amounts, unless 
otherwise provided herein,  shall be paid  in accordance  with the terms  of 
this  Agreement to his devisee, legatee  or other designee  or, if there is  not
such designee,  to his estate.

   attorney-in-fact, with full power of substitution of the Holder for the sole
   purpose of carrying out the provisions of this Agreement and taking any
   action and executing any instrument which such attorney-in-fact may deem
   necessary or advisable to accomplish the purposes hereof, which appointment
   as attorney-in-fact is irrevocable and coupled with an interest.  The Company
   as attorney-in-fact is irrevocable and coupled with interest.   The Company
   as attorney-in-fact for the Holder may, in the name and stead of the Holder,
   make and execute all conveyances, assignments and transfers of the Restricted
   Shares, and the Holder hereby ratifies and confirms all that the Company, as
   said attorney-in-fact, shall do by virtue hereof, provided that the foregoing
   shall be solely for the purpose of carrying out the provisions of this
   Agreement.  Nevertheless, the Holder shall, if so requested by the Company,
   execute and deliver to the Company all such instruments as may, in the
   reasonable judgment of the Company, be advisable for the purpose hereof.

                  (d)  Certain Rights of Holder.     The Restricted Shares, when
                       ------------------------
   issued pursuant to the provisions hereof, shall constitute issued and
   outstanding shares of

   Common Stock for all corporate purposes.  From and after the date of original
   issuance, the Holder will have the right to vote the Restricted Shares and to
   exercise all other rights, powers and privileges of a holder of Common Stock
   with respect to the Restricted Shares, with the exception that, until the
   Restricted Shares shall have become vested pursuant to the terms hereof (i)
   the Holder will not be entitled to delivery of the stock certificate or
   certificates representing the Restricted Shares; (ii) the Company will retain
   custody of the Restricted Shares; (iii) the Holder may not sell, assign,
   transfer, pledge, exchange, encumber or dispose of the Restricted Shares.  A
   material breach of any of the foregoing restrictions or a material breach of
   any of the other restrictions, terms and conditions of this Agreement with
   respect to any of the Restricted Shares, except as waived by the Company,
   will cause a forfeiture of such Restricted Shares; and (iv) the Company will
   retain custody of all distributions ("Retained Distributions") made or
   declared with respect to the Restricted Shares (and such Retained
   Distributions will be subject to the same restrictions, terms and conditions
   as are applicable to the Restricted Shares) until such time, if ever, as the
   Restricted Shares with respect to which such Retained Distributions shall
   have been made, paid or declared shall have become vested, and such Retained
   Distributions shall not bear interest or be segregated in separate accounts. 

                  (e)  Stockholders' Agreement.  Concurrently with the execution
                       -----------------------
   of this Agreement, the Holder agrees, as a condition to the receipt of the
   Restricted Shares hereunder, to execute and become a party to the

                       ----------------------
   be construed to give the Holder any right to be awarded any additional

   position or at any particular rate of remuneration, or for any particular
   period of time or to interfere in any way with the right of the Employer (or
   the right of the Holder) to terminate the employment of the Holder at any
   time, with or without Cause (as defined in the Employment Agreement dated
   January 1, 1994, as amended, between the Company and the Holder),

   cooperate with the Company to effectuate the purpose of this provision.

                       (b)  Cause.    If the Holder's employment is terminated

shall be payable by Borrower in lawful money of the United States of America and

to the contrary contained herein, interest payable hereunder shall not exceed
the maximum rate permitted by applicable law.

          The obligation of Borrower hereunder shall be absolute and
unconditional notwithstanding any defense or claim that may arise hereunder or
in connection herewith, and Borrower shall

perform Borrower's obligations hereunder without notice or demand and without

   are asserted); and

                                        -5-


<PAGE>


                  (ii)  the Pledgee may, upon five (5) Business Days' prior
   written notice to the Pledgor of the time and place, with respect to the
   Collateral owned by the Pledgor it or any part thereof which shall then be
   or shall thereafter come into the possession, custody or control of the
   Pledgee or any of its agents, sell, lease, assign or otherwise dispose of all
   or any of such Collateral, at such place or places as the Pledgee deems best,
   and for cash or on credit or for future delivery (without thereby assuming
   any credit risk), at public or private sale, without demand of performance or
   notice of intention to effect any such disposition or of time or place
   thereof (except such notice as is required above or by applicable statute and
   cannot be waived) and the Pledgee or anyone else may be the purchaser,
   lessee, assignee or recipient of any or all of the Collateral so disposed of
   at public sale (or, to the extent permitted by law, at any private sale), and
   thereafter hold the same absolutely, free from any claim or right of
   whatsoever kind, including any equity of redemption, of the Pledgor, any such
   demand, notice or right and equity being hereby expressly waived and
   released.  The proceeds of each collection, sale or other disposition under
   this Section 7, shall be applied in accordance with Section 9.  The Pledgee
   may resort to the Collateral for payment of any of the Obligations whether or

   Obligations or shall have proceeded against any party primarily or
   secondarily liable on any of the Obligations.

        SECTION 8.   Private Sale and Compliance With Law.
                     ------------------------------------

        (a)  The Pledgee shall incur no liability as a result of the sale of the
   Collateral, or any part thereof, at any private sale conducted in a
   commercially reasonable manner.  The Pledgor hereby waives any claim against
   the Pledgee arising by reason of the fact that the price at which the
   Collateral may have been sold at such a private sale was less than the price
   which might have been obtained at a public sale or was less than the
   aggregate amount of the Obligations, even if the Pledgee accepts the first
   offer received and does not offer the Collateral to more than one offeree.

        (b)  The Pledgor agrees that in any sale of any of the Collateral
   whenever a Default hereunder shall have occurred and be continuing, the
   Pledgee is hereby authorized to comply with any limitation or restriction in
   connection with such sale as it may be advised by 

                                        -6-


<PAGE>

   counsel is necessary in order to avoid any violation of applicable law
   (including, without limitation, compliance with such procedures as may
   restrict the number of prospective bidders and purchasers or require that
   such prospective bidders and purchasers be persons who will represent and
   agree that they are purchasing for their own account for investment and not
   with a view to the distribution or resale of such Collateral), or in order to
   obtain any required approval of the sale or of the purchaser by any
   governmental regulatory authority or official, and the Pledgor further 
   agrees that such compliance shall not result in such sale being considered or
   deemed not to have been made in a commercially reasonable manner, nor shall
   the Pledgee be liable nor accountable to the Pledgor for any discount allowed
   by the reason of the fact that such Collateral is sold in compliance with any
   such limitations or restrictions.

                       -----------------------
   expressly provided, the proceeds of any collection, sale or other realization
   of all or any part of the Collateral, and any other cash at the time 
   held by the Pledgee under this Agreement, shall be applied by the Pledgee:

             First, to the payment in full of all costs and expenses of such
             -----
   collection, sale or other realization, including reasonable attorneys' fees
   and legal expenses incurred by the Pledgee in connection therewith, and all
   expenses and/or advances made or incurred by the Pledgee in connection
   therewith, or incidental thereto or to the care or safekeeping of any 
   of the Collateral or in any way relating to the rights of the Pledgee
   hereunder, including reasonable attorneys' fees and legal expenses;

             Second, to the payment in full of the Obligations; and
             ------

             Third,  to the payment to the Pledgor, or the Pledgor's
             -----
        successors or assigns, or as a court of competent jurisdiction may
        direct, of any surplus then remaining from such proceeds which relate to
        the Collateral.

        SECTION 10.    No Waiver.  No failure on the part of the Pledgee or any
                       ---------
   of its agents to exercise, and no course of dealing with respect to, and no
   delay in exercising, any right, power or remedy hereunder shall operate as a
   waiver thereof; nor shall any single or partial exercise by the Pledgee or
   any of its agents of any right, power or remedy hereunder preclude any other
   or further exercise thereof or the exercise of any other right, power or
   remedy.  The remedies herein are cumulative and are not exclusive of any
   remedies provided by law.

        SECTION 11.    Continuing Security Interest.   This Agreement creates a
                       ----------------------------
   continuing security interest in the Collateral and shall remain in full force
   and effect until all Obligations shall have been paid in full.

                                        -7-

   or incident to, the enforcement of any of the provisions of this Agreement,
   or performance by the Pledgee of any of the Pledgor's obligations in respect
   of the Collateral which the Pledgor has failed or refused to perform, or any
   actual or attempted sale, or any exchange, enforcement, collection, comproise
   or settlement in respect of any of the Collateral, and for the care of the
   Collateral and defending or asserting rights and claims of the Pledgee in
   respect thereof, by litigation or otherwise; and all such expenses shall be
   Obligations secured pursuant to Section 3.

        SECTION 13.    Further Assurances. The Pledgor agrees that, from time to
                       ------------------
   time upon the written request of the Pledgee, the Pledgor will execute and
   deliver such further documents and do such other acts and things as the
   Pledgee may reasonably request in order fully to effect the purposes of this
   Agreement.

        NOW, THEREFORE, in consideration of the mutual agreements herein
   contained and other good and valuable consideration, the receipt and
   sufficiency of which are hereby acknowledged, the parties hereto do agree to
   amend the Employment Agreement as follows:

        1.   Amendment.

        Commencing at the Triggered Period, the Company agrees to pay Employee

                                                                EXHIBIT 10.70



                                  MEDICON, INC.

                  STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

          MEDICON, Inc., an Illinois corporation (the "Company"), hereby
formulates and adopts the following Stock Option Plan for Non-Employee Directors
(the "Plan") of the Company.

          1.   Purpose.  The purpose of the Plan is to secure for the Company
               -------
the benefits of the addition incentive inherent in the ownership of Class A
Common Stock, no par value, of the Company ("Common Stock") by non-employee
directors of the Company and to help the Company secure and retain the services
of such non-employee directors.  The Plan is not intended to be a formula plan
under Rule 16b-3 (c)(2)(ii), under the Securities Exchange Act of 1934.

          2.   Administration.  The Plan shall be administered by the
               --------------
compensation committee (the "Committee") appointed by the Board of Directors of
the Company (the "Board of Directors"), which Committee shall consist of two or
more directors.  The members of the Committee shall be appointed by, and may be
changed at any time and from time to time in the discretion of, the Board of
Directors.

               Subject to the provisions of the Plan, the Committee shall have
the authority (a) to exercise all of the powers granted to it under the Plan,
(b) to construe, interpret and implement the Plan and any option agreements
executed pursuant to the Plan, (c) to prescribe, amend and rescind rules
relating to the Plan, (d) to make any determination necessary or advisable in
administering the Plan, and (e) to correct any defect, supply any omission and
reconcile any inconsistency in the Plan.  The determination of the Committee on
all matters relating to the Plan or any option agreement shall be conclusive. 
No member of the Committee shall be liable for any action or determination made
in good faith with respect to the Plan or any option granted hereunder.

               Notwithstanding anything to the contrary contained herein:
(a)  until the Board of Directors shall appoint the members of the Committee,
the Plan shall be administered by the Board of Directors, and (b) the Board of
Directors may, in its sole discretion, at any time and from time to time,
resolve to administer the Plan.  In either of the foregoing events, the term
Committee as used herein shall mean the Board of Directors.



<PAGE>



               Options for members of the Committee shall be granted by the
entire Board of Directors, rather than by the Committee.

          3.   Common Stock Subject to Options.  Subject to the adjustment
               -------------------------------
provisions of Section 13 below, a maximum of 48,487 shares of Common Stock may
be made subject to options granted under the Plan.  If, and to the extent that,
options granted under the Plan shall terminate, expire or be canceled for any
reason without having been exercised, new options may be granted in respect of
the shares covered by such terminated, expired or canceled options.  The
granting and terms of such new options shall comply in all respects with the
provisions of the Plan.

               Shares sold upon the exercise of any option granted under the
Plan may be shares of authorized and unissued Common Stock, shares of issued
Common Stock held in the Company's treasury or both.

               There shall be reserved at all times for sale under the Plan a
number of shares, of either authorized and unissued shares of Common Stock
shares of Common Stock held in the Company's treasury, or both, equal to the
maximum number of shares which may be purchased pursuant to options granted or
that may be granted under the Plan.

          4.   Eligibility.  Options under the Plan may be granted to such
               -----------
directors of the Company who are not employees of the Company or any affiliate
of the Company as the Committee shall from time to time in its sole discretion
select ("Eligible Directors").

          5.   Grant of Options.
               ----------------

               (a)  Awards.   Eligible Directors may be awarded, at the
                    ------
discretion of the Committee, options to purchase shares of Common Stock with the
number of such shares to be determined by the Committee, such grants to be made
at the time the person becomes a member of the Board of Directors, and/or at a
later date as selected by the Committee.

               (b) Type of Options.  All options granted under the Plan shall be
                   ---------------
"nonqualified" stock options subject to the provisions of section 83 of the
Internal Revenue Code of 1986, as amended (the "Code") and are not intended to
qualify for special tax treatment as incentive stock options subject to the
provisions of Code section 422.  A director receiving an option pursuant to the
Plan is hereinafter referred to as an "Optionee."



<PAGE>



          6.   Price.    The option price of each share of Common Stock
               -----
purchasable under any option granted pursuant to the Plan shall be the Fair
Market Value (as defined below) thereof at the time the option is granted.

          For purposes of the Plan, "Fair Market Value" shall mean, with respect
to each share of Common Stock for any day, (a) the last reported sale price
regular way or, in case no such sale takes place on such day, the average of the
closing bid and asked prices regular way, in either case as reported on the
principal national securities exchange on which such Common Stock is listed or
admitted for trading or (b) if such Common Stock is not listed or admitted for
trading on any national securities exchange, the last reported sale price or, in
case no such sale takes place on such day, the average of the highest reported
bid and the lowest reported asked quotation for such Common Stock, in either
case as reported on the Automatic Quotation System of NASDAQ or a similar
service if NASDAQ is no longer reporting such information.  If stock is not
listed or admitted for trading on any national securities exchange or quoted on
NASDAQ or a similar service on such date, Fair Market Value shall be determined
by the Committee in its sole discretion.

          7.   Exercisability of Options.  Each option granted to an Optionee
               -------------------------
hereunder shall become exercisable as set forth in the individual option
agreements.

          All outstanding options, to the extent not vested in accordance with
the foregoing, shall be forfeited on the date of termination of a director's
service as a director of the Company.

          8.   Duration of Options.     Notwithstanding any provision of the
               -------------------
Plan to the contrary, the unexercised portion of any vested option granted under
the Plan shall automatically and without notice terminate and become null and
void at the time of the earliest to occur of the following:

               (a) The expiration of 10 years from the date on which such option
was granted;
               (b) The expiration of one year from the date the Optionee's
service with the Company shall terminate by reason of "permanent and total
disability" within the meaning of Section 22(e)(3) of the Code ("Disability"),
provided, however, that if the Optionee shall die during such one-year period,
the provisions of subparagraph (c) below shall apply;

               (c) The expiration of one year from the date of the Optionee's
death, if such death occurs during service 



<PAGE>



as a director, during the one-year period described in subparagraph (b) above or
during the three-month period described in subparagraph (e) below;

               (d) The date the Optionee's service with the Company shall
terminate by reason of "cause" (as hereafter defined).  Termination by reason of
"Cause" shall mean termination by reason of participation and conduct during the
performance of services consisting of fraud, felony, willful misconduct or
commission of any act which causes or may reasonably be expected to cause damage
to the Company or any of its affiliates; and

               (e)  The expiration of three months from the date of the
Optionee's service with the Company (including advisory services) terminates
other than by reason of death, Disability or termination for Cause.

          9.   Method of Exercise.
               ------------------

               (a)  The option or any part thereof may be exercised in
accordance with Section 2 of the individual option agreements only by giving
written notice of exercise to the Company at its principal business office,
directed to the attention of its Chief Financial Officer and by specifying the
number of whole shares of Common Stock with respect to which the option is being
exercised.  Such notice must be accompanied by payment of the full purchase
price for the number of shares purchased.

               (b)  Payment of the purchase price shall be made by the Optionee
to the Company at the time of exercise by cash, check or money order or by
Common Stock owned by the Optionee (provided that, if the Committee so requires,
such Common Stock must be owned by the Optionee for at least six months prior to
exercise).  As soon as practicable after it receives payment of the purchase
price, subject to the withholding provisions of Section 21 of this Plan, the
Company shall deliver to the Optionee a certificate or certificates for the
shares of Common Stock so purchased.



<PAGE>



          10.  Nontransferability of Options.  No option or any right granted to
               -----------------------------
the Optionee shall be assignable or transferable (whether by operation of law or
otherwise and whether voluntarily or involuntarily) other than by will or the
laws of descent and distribution.  During the Optionee's lifetime, all rights
granted to the Optionee under the Plan shall be exercisable only by the Optionee
(or the Optionees' court-appointed legal representative).

          11.  Right of Discharge Reserved.  Nothing in the Plan or in any
               ---------------------------
option shall confer upon any Optionee the right to continue as a director of the
Company or affect any right that the Company or its shareholders may have to
terminate the Optionee's service as a director.

          12.  No Stockholder Rights.  No Optionee or other person shall have
               ---------------------
any of the rights of a stockholder of the Company with respect to any shares
subject to the option until the date of the issuance of a stock certificate or
certificates to him for such shares.  Except for adjustments made pursuant to
Section 14 no adjustment shall be made for dividends, distributions or other
rights (whether ordinary or extraordinary,  and whether in cash, securities or
other property) for which the record date is prior to the date such stock
certificate is issued.

          13.  Adjustments.
               -----------

               (a)  Upon Changes in Capitalization.  To the extent specified by
                    ------------------------------
the Board of Directors, the number of shares of Stock that may be issued
pursuant to options under the Plan, the number of shares of Stock subject to
options, the exercise price of options theretofore granted under the Plan and
the amount payable by a grantee in respect of an option shall be appropriately
adjusted (as the Board of Directors may determine) for any change in the number
of issued shares of Stock resulting from the subdivision or combination of
shares of Stock or other capital adjustments, or the payment of a stock dividend
after the effective date of the Plan, or other change in such shares of Stock
effected without receipt of consideration by the Company; provided that any
options covering fractional shares of Stock resulting from any such adjustment
shall be eliminated.  Adjustments under this Section 14 shall be made by the
Board of Directors, whose determination as to what adjustments shall be made,
and the extent thereof, shall be final, binding and conclusive.

               (b)  Other.  In the event of any acquisition, divestiture or any
                    -----
other corporate transaction of any kind involving the Company or its
subsidiaries which the Board of Directors, in its discretion, determines to be
of such a kind or nature as to make appropriate an amendment or 



<PAGE>

Plan, the Board of Directors, in its discretion, may make such amendment or
adjustment.  Without limiting the generality of the foregoing, the Board of
Directors, in its discretion, may, in connection with any such corporate
transaction, (a) reduce or increase the Minimum EBITDA Targets, the Maximum
EBITDA Targets and/or the EBITDA Factors and/or (b) amend any other terms or
provisions of the Plan, all as it deems appropriate to effectuate the intent and
purposes of the Plan.

          14.  Form of Agreements with Optionees.  Each option granted
               ---------------------------------
pursuant to the Plan shall be in writing and shall have such form, terms and 
provisions, not inconsistent with the provisions of the Plan, as the Committee
shall provide for such option.

          15.  Purchase for Investment.  Whether or not the options and shares
               -----------------------
covered by the Plan have been registered under the Securities Act of 1933, as 
amended, each person exercising an option under the Plan may be required by the 
Company to give a representation in writing that such person is acquiring such 
shares for investment and not with a view to, or for sale in connection with, 
the distribution of any part thereof.  The Company will endorse any 
necessary legend referring to the foregoing restriction upon the certificate or 
certificates representing any shares issued or transferred to the Optionee upon 
the exercise of any option granted under the Plan.

          16.  Puts and Calls.

such date, Fair Market Value as defined above; and if the Stock is not listed or

a similar service on such date, the value equal to four times the EBITDA for the
12-month period ending at the end of the month proceeding the put or call
exercise divided by the outstanding "Shares" (as such term is defined in the
Amended and Restated Articles of Incorporation) unless the Committee determines
that it does not reflect the Fair Market Value,in which case it shall mean the
Fair Market Value.

               (b)  Put Option.  During the 120-day period following the date
                    ----------

appointed legal representative (or the person or persons to whom such options
pass under the Optionee's will or, if applicable, pursuant to the laws of
descent and distribution) may cause the Company to purchase the option shares at
a purchase price per share equal to Put/Call Value (determined on the date of
the written notice described in Section 17(c)); provided, however, that this
                                                --------  -------
provision shall have no applicability if (i) the Common Stock is publicly traded
on a national securities exchange throughout such 120-day period or (ii) such
purchase by the Company would (x) constitute or cause a breach or violation of,
or a default (whether immediately or with notice or lapse of time or both)
under, any debt agreement of the Company or of any of its subsidiaries whether
currently in existence or entered into subsequent to the date hereof), (y)
require the consent or approval of the holders of any class of the Company's
capital stock pursuant to the Company's Amended and Restated Articles of
Incorporation and such consent or approval is not obtained, or (z) violate any 
law applicable to the Company.

               (c)  Closing.  To the extent applicable, the call and put options
                    -------
described in Sections 17(a) and (b) shall be exercisable by delivering to the
Optionee or the Company, as the case may be, within such 120-day period, written
notice of intention to exercise such option.  The closing of the purchase and
sale of shares of Common Stock pursuant to the exercise of such options shall
take place on the 11th day (or if not a business day, the next business day)

subsidiaries terminates, or in connection with a Change of Control (as defined
in the Amended and Restated Articles of Incorporation), the Committee, in its
discretion, by written notice to the Optionee may cancel all options then
exercisable (as determined under Section 7 hereof), or any part thereof, and the
Company shall pay to the Optionee, as soon as practicable thereafter, an amount
in cash equal to the excess of (i) the aggregate Fair Market Value of the shares
of Common Stock subject to the option or part hereof canceled (determined as of
the date the Committee, provide written notice thereof to the Optionee) over
(ii) the aggregate option exercise price of the shares of Common Stock subject
to the option or part thereof canceled.

          17.  Notices.  All notices and other communications hereunder shall be
               -------

Either party may, by notice, change the address to which notice to such party is
to be given.

          18.  Termination and Amendment of Plan and Options.  Unless the Plan
               ---------------------------------------------
shall theretofore have been terminated a hereinafter provided, options may be
granted under the Plan prior to the tenth anniversary of the Effective Date on
which the Plan will expire, except as to options then outstanding under the
Plan. Such options shall remain in effect until they have been exercised, have
expired or have been canceled.

          The Plan may be terminated or amended at any time by the Board of
Directors; provided, however, that (i) any such amendment shall comply with all
applicable laws and applicable stock exchange listing requirements, and (ii) any
amendment for which stockholder approval is required by law or in order to
maintain continued qualification of the Plan under Rule 16b-3 shall not be
effective until such approval has been obtained.



<PAGE>



          No termination, modification or amendment of the Plan, without the
consent of the Optionee, may adversely affect the rights of such person with
respect to such option.

          19.  Effective Date of Plan.  The Plan shall become effective upon its
               ----------------------
adoption by the Board of Directors (the "Effective Date"), subject, however, to
its approval by the Company's shareholders within 12 months after the date of
such adoption.

          20.  Government and Other Regulations.  The obligation of the Company
               --------------------------------
with respect to options granted under the Plan shall be subject to all
applicable laws, rules and regulations and such approvals by any governmental
agency as may be required, including, without limitation, the effectiveness of
any registration statement required under the Securities Act of 1933, as
amended, and the rules and regulations of any securities exchange on which the
Common Stock may be listed.

          21.  Withholding.  The Company's obligation to deliver the shares of
               -----------
Common Stock in respect of any option granted under the Plan shall be subject to
all applicable federal, state and local tax withholding requirements.  Federal,
state and local withholding tax due upon the exercise of any option, may be paid
in shares of Common Stock (including the withholding of shares subject to an
option).

          22.  Separability.  If any part of the Plan is declared by any court
               ------------
or governmental authority to be unlawful or invalid, such unlawfulness or
invalidity shall not invalidate any portion of the Plan not declared to be
unlawful or invalid. Any Section or part of a Section so declared to be unlawful
or invalid shall, if possible, be construed in a manner which will give effect
to the terms of such Section or part of a Section to the fullest extent possible
while remaining lawful and valid.

          23.  Non-Exclusivity of the Plan.  Neither the adoption of the Plan by
               ---------------------------
the Board of Directors nor the submission of the Plan to the Shareholders of the
Company for approval shall be construed as creating any limitation on the power
of the Board of Directors to adopt such other incentive arrangements as it may
deem desirable, including, without limitation, the granting of stock options and
the awarding of stock and cash otherwise than under the Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.
          24.  Exclusion from Pension and Profit-Sharing Computation.  By
               -----------------------------------------------------
acceptance of an option, each Optionee 



<PAGE>



shall be deemed to have agreed that such grant is special incentive compensation
that will not be taken into account, in any manner, as salary, compensation or
bonus in determining the amount of any payment under any pension, retirement or
other employee benefit plan of the Company or any of its affiliates.  In
addition, such option will not affect the amount of any life insurance coverage,
if any provided by the Company on the life of the Optionee.

          25.  Governing Law.  The Plan shall be governed by, and construed in
               -------------
accordance with, the laws of the State of Illinois.

               -------


          The purpose of this Plan (as defined in Section 5) is to promote the
interests of Medicon, Inc. (the "Company") by (a) attracting, motivating and
retaining executive personnel of outstanding ability; (b) focusing the attention
of executive management on achievement of sustained long term results; (c)

          2.1  The Plan shall be administered by the compensation committee (the
"Committee") appointed by the Board of Directors of the Company (the "Board"),
which Committee shall consist of two or more directors, and, to the extent
necessary to comply with Rule 16b-3 of the Securities Exchange Act of 1934 (the
"Act"), or any successor rule thereto, each director shall be a "disinterested
person" within the meaning of the Act.  To the extent necessary to comply with
section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"),

meaning of the Code; provided, however, that if such member is not an outside
director his or her action shall be valid nonetheless.  The members of the

time in the discretion of, the Board.

          2.2  The Committee shall have the authority (a) to exercise all of the
powers granted to it under the Plan,  (b) to construe, interpret and implement
the Plan and any option agreements executed pursuant to the Plan,  (c)  to
prescribe, amend and rescind rules relating to the Plan,  (d) to make any
determination  necessary or advisable in administering the Plan,  (e)  to
correct any defect, supply any omission and reconcile any inconsistency in the
Plan,  (f) to determine EBITDA (as defined in Section 5), and  
(g) to determine and to adjust Minimum and Maximum EBITDA Targets.

          2.3  The determination of the Committee on all matters relating to the
Plan or any option agreement shall be conclusive.

determination made in good faith with respect to the Plan or any option granted
hereunder.

          2.5  Notwithstanding anything to the contrary contained herein:  (a) 
until the Board shall appoint the members of the Committee, the Plan shall be

any time and from time to time, resolve to administer the Plan.  In either of
the foregoing events, the term Committee as used herein shall mean the Board.

for any reason (other than exercise or other than an option, or part thereof,
that is canceled by the Committee and for which cash is paid in respect thereof)
shall again become available for award under the Plan.

          4.2  Types of Shares.    Shares of Stock subject to issuance pursuant
               ---------------
to the Plan shall be authorized and unissued shares or treasury shares.

SECTION 6.     Stock Options.
               -------------

          6.1  Grant and Type of Stock Options.
               -------------------------------

               (a)  General.  Subject to the terms of the Plan, the Committee
                    -------
may grant options to purchase shares of Stock in such amounts and subject to
such terms and conditions as the Committee shall from time to time in its sole
discretion determine in accordance with applicable law.

               (b)  Types of Options Under Plan.  Options granted under the Plan
                    ---------------------------
may be either:  (i) "nonqualified" stock options subject to the provisions of
section 83 of the Code, or (ii) options intended to qualify for incentive stock
option treatment described in Code Section 422.

          6.2  Agreements Evidencing Options.
               -----------------------------

               (a)  General.  Options granted under the Plan shall be evidenced
                    -------
by written agreements, which shall (i) contain such provisions, not inconsistent
with the terms of the Plan, as the Committee may in its sole discretion deem
necessary or desirable and (ii) be referred to herein as "option agreements." 
If the grantee is party to an employment or consulting agreement the terms of
which relate to stock options and which are inconsistent with the terms of any
such option agreement, the terms of such employment or consulting agreement
shall govern with respect to any terms relating to options granted hereunder.

               (b)  Certain Terms. Each option agreement shall set forth the
                    -------------
number of shares of Stock subject to the option granted thereby and the amount
(the "option exercise price") payable by the grantee to the Company in
connection with the exercise of the option evidenced thereby.  Options shall be
granted with an exercise price of no less than Fair Market Value at the time of
grant.  Each option agreement shall set forth the period during which and the
conditions subject to which the option evidenced thereby shall become
exercisable.















<PAGE>







                                                                               5

          6.3  Special ISO Requirements.
               ------------------------

          In order for a grantee to receive special tax treatment with respect
to stock acquired under an option intended to be an incentive stock option, the
grantee of such option must be, at all times during the period beginning on the
date of grant and ending on the day three months before the date of exercise of
such option, an employee of the Company or any of the Company's parent or
subsidiary corporations (within the meaning of Code section 424), or of a
corporation or a parent or subsidiary corporation of such corporation issuing or
assuming a stock option in a transaction to which Code section 424(a) applies. 
The aggregate Fair Market Value, determined as of the date an option is granted,
of the Stock for which any grantee may be awarded incentive stock options which
are first exercisable by the grantee during any calendar year under the Plan
(and any other stock option plan to be taken into account under Code section
422(d) shall not exceed $100,000.  If an option granted under the Plan is
intended to be an incentive stock option, the option exercise price may not be
less than Fair Market Value of the Stock on the date of its grant, and if the
grantee at the time of grant, owns stock possessing 10% or more of the total
combined voting power of all classes of stock of the grantee's employer
corporation or of its parent or subsidiary corporation, then (i) the option
exercise price per share shall in no event be less than 110% of the Fair Market
Value of the Stock on the date of such grant and (ii) such option shall not be
exercisable after the expiration of five years after the date such option is
granted.

          6.4  Exercisability of Options.
               -------------------------

               (a)  Basic Exercisability Requirements. The options shall be
                    ---------------------------------
first exercisable with respect to the shares of stock subject thereto, only if
(i) the Nine Year Vesting Date is reached upon which time the options shall be
fully exercisable, or (ii) an earlier date at which the Cumulative
Exercisability Percentage is greater than zero.  An option may be exercised only
with respect to the applicable Cumulative Exercisability Percentage of the
number of shares covered by such option until reaching the Nine Year Vesting
Date, upon which time the option will be 100% exercisable.

               (b)  EBITDA Targets.  The Minimum EBITDA Target and the Maximum
                    --------------
EBITDA Target for any Fiscal Year are set forth in the individual option
agreements and are subject to Committee determination as set forth in such
option agreements.  The Minimum and Maximum EBITDA Targets for various Fiscal
Years can be adjusted by the Committee (prior to such Fiscal Year), but it is
the intention that if















<PAGE>








so adjusted by the Committee the Maximum EBITDA Target for each succeeding
Fiscal Year shall be no less 125% of the actual EBITDA for the prior Fiscal Year
and the Minimum EBITDA Target for each succeeding Fiscal Year shall be no less
than 121.25% of the actual EBITDA for the prior Fiscal Year.

               (c)  Determination of Cumulative Exercisability Percentage.
                    -----------------------------------------------------

                    (i)  Expiration.    If (A) a grantee's Minimum EBITDA Target
                         ----------
     is not achieved in any Fiscal Year and (B) a grantee's employment is
     terminated prior to the Nine Year Vesting Date, then none of the grantee's
     options which have been or may be granted under this Plan shall be
     exercisable and all such options shall be cancelled.

                    (ii) Cumulative Exercisability Percentage.   If the Minimum
                         ------------------------------------
     EBITDA Target is achieved for any Fiscal Year during the Performance Cycle,
     the Cumulative Exercisability Percentage will be increased by ten
     percentage points at the end of such Fiscal Year.  If the Maximum EBITDA
     Target is achieved for any Fiscal Year during the Performance Cycle, the
     Cumulative Exercisability Percentage will be increased by twenty percentage
     points at the end of such Fiscal Year.  If the actual EBITDA for such
     Fiscal Year falls between the Minimum EBITDA Target and Maximum EBITDA
     Target for any Fiscal Year during the Performance Cycle, the Cumulative
     Exercisability Percentage will be increased by between ten and twenty
     percentage points to be calculated on a straight-line interpolation basis.

               (d)  Carryover for Targets Not Met.     For each Fiscal Year
                    -----------------------------
during the Performance Cycle in which the Maximum EBITDA Target is not
satisfied, the difference between twenty percentage points and the actual
increase in the Cumulative Exercisability Percentage for such Fiscal Year (the
"Missed Target Percentage") shall be carried over to the subsequent five Fiscal
Years (regardless of whether or not they fall with the Performance Cycle).  One-
fifth of the Missed Target Percentage will be available for each such year if
the Maximum EBITDA Target is met for such year, one-tenth of the Missed Target
Percentage will be available for each such year if the Minimum EBITDA Target is
met for such year, and if the EBITDA falls between the Minimum EBITDA Target and
the Maximum EBITDA Target between one-fifth and one-tenth of the Missed Target
Percentage will be available calculated on a straight-line interpolation basis. 
The Committee will set the Minimum and Maximum EBITDA Targets for Fiscal Years
beyond the Performance Cycle.

               (e)  General Exercisablity Provisions.
                    --------------------------------

                    (i)  Each option shall terminate and cease to be exercisable
     on the tenth anniversary of the date of grant thereof; and

                    (ii) Each option, once exercisable, may be exercised from
     time to time as to all or part of the full number of shares as to which
     such option shall then be exercisable.

               (f)  Notice of Exercise; Exercise Date.
                    ---------------------------------

                    (i)  An option shall be exercisable by the filing of a
     written notice of exercise with the Company, on such form and in such
     manner as the Committee shall in its sole discretion prescribe, and by
     payment in accordance with Section 6.5.

                    (ii) For purposes of the Plan, the "option exercise date"
     shall be deemed to be the first business day immediately following the date
     written notice of exercise is received by the Company.

          6.5  Payment of Option Price.
               -----------------------

               (a)  Tender Due Upon Notice of Exercise.     Unless the
                    ----------------------------------
applicable option agreement otherwise provides or the Committee in its sole
discretion otherwise determines, (i) any written notice of exercise of an option
shall be accompanied by payment of the full purchase price for the shares being
purchased and (ii) the grantee shall have no right to receive shares of Stock
with respect to an option exercise prior to the option exercise date.

               (b)  Manner of Payment.  Payment of the option exercise price
                    -----------------
shall be made in any combination of the following:

                    (i)  by certified or official bank check payable to the
     Company (or the equivalent thereof acceptable to the Committee);

                    (ii) with the consent of the Committee in its sole
     discretion, by personal check (subject to collection); and

                    (iii)     if and to the extent provided in the applicable
     option agreement, by delivery of previously acquired shares of Stock owned
     by the grantee for at least six months having a Fair Market Value
     (determined as of the option exercise date) equal to the portion of the
     option exercise price being paid














<PAGE>







                                                                               8


     thereby, provided that the Committee may require the grantee to furnish 
     an opinion of counsel acceptable to the Committee to the effect that such
     delivery would not result in the grantee incurring any liability under
     Section 16(b) of the Act or any other federal or state securities laws,
     rules or regulations and does not require any Consent (as defined in
     Section 8.2).

               (c)  Issuance of Shares. As soon as practicable after receipt of
                    ------------------
full payment, the Company shall, subject to the provisions of Section 8, deliver
to the grantee one or more certificates for the shares of Stock so purchased,
which certificates may bear such legends as the Company may deem appropriate
concerning restrictions on the disposition of the shares in accordance with
applicable securities laws, rules and regulations or otherwise.

          6.6  Termination of Employment.
               -------------------------

               (a)  General Rule.   All options granted to a grantee shall
                    ------------
terminate and no longer be exercisable upon such grantee's termination of
employment for any reason, except to the extent post-employment exercise of the
exercisable portion of an option is permitted in accordance with this Section
6.6.

               (b)  Cause.  All options granted to a grantee shall terminate
                    -----
and expire on the day the grantee's employment with the Company and its
subsidiaries is terminated for Cause.  For purposes of the Plan, a grantee's
employment shall be deemed to be terminated for "Cause" if (i) such grantee is
discharged following the conviction of the grantee of any felony involving
intentional conduct on the part of the grantee, the conviction of the grantee of
any lesser crime or offense involving the illegal use or conversion of property
of the Company or its subsidiaries, the willful misconduct by the grantee in
connection with the performance of the grantee's duties or the violation of any
nonsolicitation, confidentiality or noncompetition covenant specified in an
employment agreement or other contractual arrangement, or (ii) such grantee
terminates his employment with the Company and its subsidiaries and the
Committee determines, within 90 days after the grantee's termination date, that
such grantee's employment could have been terminated for Cause pursuant to
clause (i).

               (c)  Death and Disability.    If a grantee's employment with the
                    --------------------
Company and its subsidiaries terminates by reason of death or disability (as
defined in section 22(e)(3) of the Code), such grantee's options shall be
exercisable, but only to the extent already exercisable immediately prior to
such death or disability, by the grantee under Section 6.4 hereof, or as the
case may be, by













<PAGE>





                                                                               9

such grantee's court-appointed legal representative or, in the case of the
grantee's death, by the person or persons to whom such options pass under the
grantee's will (or, if applicable, pursuant to the laws of descent and
distribution).  Such options shall remain exercisable through and until the
earlier of (i) in the case of a grantee who dies or becomes disabled, one year
after the grantee's termination by reason of death or disability, (ii) the date
on which such options terminate or expire in accordance with the other
provisions of the Plan and the option agreement.

               (d)  Regular Termination; Leaves of Absence. If the grantee's
                    --------------------------------------
employment terminates for reasons other than as provided in Section 6.6(b) or
(c), the portion, if any, of options granted to such grantee that were
exercisable immediately prior to such termination of employment may be exercised
until the earlier of (i) 90 days after the grantee's date of termination, and
(ii) the date on which such options terminate or expire in accordance with the
other provisions of the Plan and the option agreement.  The Committee may in its
discretion determine (x) whether any leave of absence (including short-term or
long-term disability or medical leave) shall constitute a termination of
employment for purposes of the Plan and (y) the impact, if any, of any such
leave on outstanding awards under the Plan.

          6.7  Puts and Calls.
               --------------

               (a)  Call Option.   Upon termination of the grantee's employment
                    -----------
with the Company and its subsidiaries, the Company shall have an option to
purchase from such grantee (or from any legal representative or transferee, by
will or the laws of descent and distribution or otherwise, of such grantee) all
or any portion of shares ("option shares") acquired by such grantee pursuant to
the exercise of options granted under this Plan (the "call option").  Such call
option may be exercised during the later of the following periods:  (i) the 120-
day period following the date of the grantee's termination of employment or (ii)
the 120-day period following the expiration of six months from the acquisition
of the option shares.  Such call option shall be at a purchase price per share
equal to (i) if the grantee's employment terminates other than for Cause,
"Put/Call Value" (as defined in the next sentence and as determined on the date
of the written notice described in Section 6.7(c)), and (ii) if the grantee's
employment with the Company and its subsidiaries terminates for Cause, the
lesser of Put/Call Value (determined on the date of the written notice described
in Section 6.7(c)) and the option exercise price.  Such call option shall have
no applicability if the Stock is publicly traded on a national securities
exchange, throughout such 120-day period except
















<PAGE>







                                                                              10

in the event the grantee's employment is terminated for Cause.  "Put/Call Value"
shall mean:  if the Stock is listed or admitted for trading on any national
securities exchange or quoted on NASDAQ or a similar service on such date, Fair
Market Value as defined above; and if the Stock is not listed or admitted for
trading on any national securities exchange or quoted on NASDAQ or a similar
service on such date, the value equal to four times the EBITDA for the 12-month
period ending at the end of the month proceeding the put or call exercise
divided by the outstanding "Shares" (as such term is defined in the Amended and
Restated Articles of Incorporation) unless the Committee determines that it does
not reflect the Fair Market Value, in which case it shall mean the Fair Market
Value.

               (b)  Pub Option Upon Death or Disability.    Upon termination of
                    -----------------------------------
the grantee's employment with the Company and its subsidiaries by reason of
death or disability, the grantee, the grantee's court-appointed legal
representative (or person or the persons to whom such options pass under the
grantee's will or, if applicable, pursuant to the laws of descent and
distribution) may cause the Company to purchase the option shares (the "put
option").  Such put option may be exercised during the later of the following
two periods:  (i) the 120-day period following the date that the grantee's
employment terminates by reason of death or disability, or (ii) the 120-period
following the expiration of six months from the acquisition of the option
shares.  Such put option shall be for a purchase price per share equal to
Put/Call Value (as defined in the previous paragraph and as determined on the
date of the written notice described in Section 6.7(c)).  Such put option shall
have no applicability if (i) the Stock is publicly traded on a national
securities exchange throughout such 120-day period or (ii) such purchase by the
Company would (x) constitute or cause a breach or violation of, or a default
(whether immediately or with notice or lapse of time or both) under, any debt
agreement of the Company or of any of its subsidiaries (whether currently in
existence or entered into subsequent to the date hereof), (y) require the
consent or approval of the holders of any class of the Company's capital stock
pursuant to the Company's Amended and Restated Articles of Incorporation and
such consent or approval is not obtained, or (z) violate any law applicable to
the Company.

               (c)  Closing.  To the extent applicable, the call and put options
                    -------
described in Sections 6.7(a) and (b) shall be exercisable by delivering to the
grantee or the Company, as the case may be, within such 120-day period, written
notice of intention to exercise such option.  The closing of the purchase and
sale of shares of Stock pursuant to the exercise of such options shall take
place on the 15th















<PAGE>





                                                                              11

day (or if not a business day, the next business day) following the date of the
written notice at the offices of the Company.  At such closing, the grantee
shall deliver to the Company, duly endorsed for transfer, certificates
representing all of the shares of Stock being purchased and sold at such closing
against payment therefor which, at the option of the Company, shall be made
either by certified or bank cashier's check for the purchase price.

               (d)  Option Cancellation.     During the 120-day period following
                    -------------------
the date the grantee's employment with the Company and its subsidiaries
terminates, or in connection with a Change of Control (as such term is defined
in the Amended and Restated Articles of Incorporation), the Committee, in its
discretion, by written notice to the grantee may cancel all options then
exercisable (as determined under Section 6.4 hereof), or any part thereof, and
the Company shall pay to the grantee, as soon as practicable thereafter, an
amount in cash equal to the excess of (i) the aggregate Fair Market Value of the
shares of Stock subject to the option or part thereof canceled (determined as of
the date the Committee provides written notice thereof to the grantee) over (ii)
the aggregate option exercise price of the shares of Stock subject to the option
or part thereof canceled.

SECTION 7.     Amendment of the Plan; Modification of Options.
               ----------------------------------------------

          7.1  Plan Amendments.    The Committee may, without shareholder
               ---------------
approval, at any time and from time to time, suspend, discontinue or amend the
Plan in any respect whatsoever, except that no such amendment shall materially
and adversely impair any rights under any option theretofore granted under the
Plan without the consent of the grantee of such option.  Furthermore, except as
and to the extent otherwise permitted by Section 11 or 17, no such amendment
shall, without shareholder approval:

               (a)  Subject to Section 7.2, materially increase the
     benefits accruing to grantees under the Plan;

               (b)  materially increase, beyond the amounts set forth in Section
     4, the number of shares of Stock in respect of which options may be issued
     under the Plan;

               (c)  materially modify the designation in Section 3 of the class
     of persons eligible to receive options under the Plan;


















<PAGE>







                                                                              12

               (d)  provide for the grant of options having an exercise price of
     less than a 100% of the Fair Market Value of Stock on the date of grant;

               (e)  permit any stock option to be exercisable more than ten
     years after the date of grant;

               (f)  extend the term of the Plan beyond the period set forth in
     Section 20;

               (g)  if the Company has a class of equity securities registered
     under Section 12 of the Act at the time of such proposed amendment result
     in an "material increase" in the benefits accruing to participants under
     the Plan, as provided in 17 C.F.R. Section 240.16(b)-3(b)(2)(C) as
     interpreted by the Securities and Exchange Commission in interpretative
     guidance; or

               (h)  would result in a material modification of the Plan within
     the meaning of Code section 162(m) that would require shareholder approval
     if the Plan is intended to qualify under section 162(m) of the Code as
     performance based compensation.

          7.2  Option Modifications.    With the consent of the grantee and
               --------------------
subject to the terms and conditions of the Plan, the Committee may, in its sole
discretion, amend outstanding option agreements with such grantee, including,
without limitation, any amendment that would (i) accelerate the time or times at
which an option may become exercisable and/or (ii) extend the scheduled
termination or expiration date of the option.


SECTION 8.     Restrictions.
               ------------

          8.1  Consent Requirements.    If the Committee shall at any time
               --------------------
determine that any Consent (as hereinafter defined) is necessary or desirable as

exemption from the requirement that any such listing, qualification or
registration be made, (d) any and all consents, waivers, clearances and

Incorporation.


SECTION 9.     Nontransferability.
               ------------------

          No option granted to any grantee shall be assignable or transferable
by the grantee (whether by operation of law or otherwise and whether voluntarily
or involuntarily) other than by will or by the laws of descent and distribution.
During the lifetime of the grantee, all rights with respect to any option
granted to the grantee shall be exercisable only by the grantee or the grantee's
court-appointed legal representative.


SECTION 10.    Withholding Taxes.

                                                                              14

thereto or to the delivery of any shares of Stock under the Plan.

          10.2 Use of Shares. Subject to the Committee's consent, a grantee may
               -------------
elect to satisfy all or part of the foregoing withholding requirements by
delivery of unrestricted shares of Stock owned by the grantee for at least six
months (or such other period as the Committee may determine) having a Fair
Market Value (determined as of the date of such delivery by the grantee) equal
to all or part of the amount to be so withheld, provided that the Committee may
require, as a condition of accepting any such delivery, the grantee to furnish
an opinion of counsel acceptable to the Committee to the effect that such
delivery would not result in the grantee incurring any liability under Section
16(b) of the Act or any other federal or state securities laws, rules or
regulations.


SECTION 11.    Adjustments.
               -----------

          11.1 Upon Changes in Capitalization.    To the extent specified by the
               ------------------------------
Committee, the number of shares of Stock that may be issued pursuant to options
under the Plan, the number of shares of Stock subject to options, the exercise
price of options theretofore granted under the Plan and the amount payable by a
grantee in respect of an option shall be appropriately adjusted (as the
Committee may determine) for any change in the number of issued shares of Stock
resulting from the subdivision or combination of shares of Stock or other
capital adjustments, or the payment of a stock dividend after the effective date
of the Plan, or other change in such shares of Stock effected without receipt of
consideration by the Company; provided that any options covering fractional
shares of Stock resulting from any such adjustment shall be eliminated. 
Adjustments under this Section 11 shall be made by the Committee, whose
determination as to what adjustments shall be made, and the extent thereof,
shall be final, binding and conclusive.

          11.2 Other.    In the event of any acquisition, divestiture or any
               -----
other corporate transaction of any kind involving the Company or its
subsidiaries which the Committee, in its discretion, determines to be of such a
kind or nature as to make appropriate an amendment or adjustment to the Plan in
order to effectuate the intent and purposes of the Plan, the Committee, in its
discretion, may make such amendment or adjustment.  Without limiting the
generality of the foregoing, the Committee, in its discretion, may, in
connection with any such corporate transaction, (a) reduce or increase the
Minimum EBITDA Targets and/or the Maximum EBITDA Targets and/or (b) amend any
other terms or provisions of the Plan, all as it deems

                                                                              15

appropriate to effectuate the intent and purposes of the Plan.


SECTION 12.    Right of Discharge Reserved.
               ---------------------------

          Nothing in the Plan or in any option agreement shall confer upon any
person the right to continue in the employment of the Company or any subsidiary
or affect or restrict any right which the Company or any subsidiary may have to
terminate the employment of such person.


SECTION 13.    No Rights as a Shareholder.
               --------------------------

          No grantee or other person shall have any of the rights of a
shareholder of the Company with respect to shares of Stock subject to an option
until the issuance of a stock certificate to such grantee for such shares of
Stock.  Except as otherwise provided in Section 11, no adjustment shall be made
for dividends, distributions or other rights (whether ordinary or extraordinary,
and whether in cash, securities or other property) for which the record date is
prior to the date such stock certificate is issued.


SECTION 14.    Nature of Payments.
               ------------------

          14.1 Consideration. All options, shares or payments hereunder shall be
               -------------
granted, issued, delivered or paid, as the case may be, in consideration of
services performed for the Company or for its subsidiaries by the grantee.

          14.2 Other Plans.   No options, shares or payments hereunder shall,
               -----------
unless otherwise determined by the Committee and expressly set forth in the
option agreement, be taken into account in computing the grantee's salary or
compensation for the purposes of determining any benefits under (a) any pension,
retirement, life insurance or other benefit plan of the Company or any
subsidiary or (b) any agreement between the Company or any subsidiary and the
grantee.

          14.3 Waiver.   By accepting an option under the Plan, the grantee
               ------
thereby waives any claim to the continued exercisability of an option or to
damages or severance entitlement related to non-continuation of the option
beyond the period provided herein or in the applicable option agreement,
notwithstanding any contrary provision in any written employment contract with
the grantee, whether any such contract is executed before or after the grant
date of the option.

SECTION 15.    Non-Uniform Determinations.
               --------------------------

          The Committee's determinations under the Plan need not be uniform and
may be made by it selectively among persons who receive, or are eligible to
receive, options under the Plan (whether or not such persons are similarly
situated).  Without limiting the generality of the foregoing, the Committee
shall be entitled, among other things, to make non-uniform and selective
determinations, and to enter into non-uniform and selective option agreements,
as to (a) the persons to receive options under the Plan, (b) the terms and
provisions of options under the Plan and (c) the treatment of leaves of absence
pursuant to Section 6.6(d).


SECTION 16.    Other Payments or Options.
               -------------------------

          Nothing contained in the Plan shall be deemed in any way to limit or
restrict the Company, any subsidiary or the Committee from making any option,
award or payment to any person under any other plan, arrangement or
understanding, whether now existing or hereafter in effect; provided, however,
that the option agreement may contain (but shall not be required to contain)
such provisions as the Committee deems appropriate to insure that the penalty
provisions of section 4999 of the Code will not apply with respect to any option
granted under the Plan.


SECTION 17.    Reorganization.
               --------------

          In the event that the Company is merged or consolidated with another
corporation and, whether or not the Company shall be the surviving corporation,
there shall be any change in the shares of Stock by reason of such merger or
consolidation, or in the event that all or substantially all of the assets of
the Company are acquired by another person, or in the event of a Change of
Control after the date of the adoption of this Plan or in the event of a
reorganization or liquidation of the Company (each such event being hereinafter
referred to as a "Reorganization Event") or in the event that the Board shall
propose that the Company enter into a Reorganization Event, then the Committee
may in its discretion, by written notice to a grantee, provide that such
grantee's options will be terminated unless exercised within 30 days (or such
longer period as the Committee shall determine in its sole discretion) after the
date of such notice.  The Committee also may in its discretion by written notice
to a grantee provide that all or some of the restrictions on any of his options
may lapse in the event of a Reorganization Event
