GOVERNMENT REGULATION
 
    REGULATORY ENVIRONMENT.
 
    Virtually  all aspects of the health  care industry are subject to extensive
federal and  state  regulation.  Various  federal  and  state  laws,  which  are
interpreted  and  enforced  by  courts  and  regulatory  authorities  with broad
discretion, regulate the  relationships between the  Company and its  affiliated
physicians,  hospitals and ancillary  health care providers.  These laws include
(i) the anti-fraud and abuse provisions  of the Medicaid and Medicare  statutes,
which  prohibit certain business practices and relationships that may affect the
provision and cost of health care  services reimbursable under the Medicaid  and
Medicare  programs, including the solicitation,  payment, receipt or offering of
any direct or  indirect remuneration  for the referral  of patients  or for  the
provision  of goods or services; (ii) the anti-kickback provisions of the Social
Security Act, which restrict physician referrals to certain providers, including
hospitals, with which the physician has a financial arrangement; (iii) the  laws
of   some   states,  which   prohibit  physicians   from  splitting   fees  with
non-physicians and prohibit non-physician entities from engaging in the practice
of medicine;  (iv) the  laws of  most  states, which  regulate the  business  of
insurance  and the operation of HMOs; (v) federal antitrust laws, which prohibit
anti-competitive conduct, including price fixing, concerted refusals to deal and
division of market; and (vi) federal and state civil and criminal statutes which
prohibit health  care providers  from  fraudulently or  wrongfully  overcharging
governmental or other third party payors for health care services. Violations of
these  laws could result  in substantial civil  or criminal penalties, exclusion
from the  Medicaid  and Medicare  programs,  and suspension  or  debarment  from
obtaining  government  contracts. Although  the Company  seeks to  structure its
operations and  arrange its  business relationships  so as  to comply  with  all
applicable  legal  requirements (including  the  laws and  regulations mentioned
above), there can be no assurance  that, upon review of the Company's  business,
courts  or regulatory authorities might not adopt or assert a contrary position,
that the  Company's  present or  future  operations might  not  be  successfully
challenged   as  violating,   or  determined   to  have   violated,  such  legal
requirements, or  that  new  laws  and regulations,  or  the  interpretation  of
existing laws and regulations, might not require the Company to restructure some
or   all  of  its   operations  or  adversely   effect  the  Company's  business
relationships. Any  such result  could have  a material  adverse effect  on  the
Company.
 
    While  the  Company's Medicaid  HMO is  not  presently subject  to licensure
requirements in  the  District of  Columbia,  a  bill which  would  require  the
licensure  of  HMOs in  the  District of  Columbia  and subject  the  Company to
additional regulatory  requirements was  approved by  the District  of  Columbia
Council  on November 7, 1996  and signed by the Mayor  on December 24, 1996. The
bill is currently pending for congressional review prior to approximately  April
11, 1997. If the final legislation includes the licensure provision contained in
the  current  bill, the  Company will  have to  apply for  a license.  While the
Company expects  that its  Medicaid HMO  in  the District  of Columbia  will  be
granted a license to operate as an HMO in the District of Columbia, there can be
no  assurance  that such  license will  be granted.  The Company's  inability to
obtain a license to operate as an HMO in the District for any reason would  have
a material adverse effect on the Company.
 
    FEDERAL  AND STATE INVESTIGATIONS.   As part of  the pervasive regulation of
the health care  industry by  federal and state  governments, these  governments
have  begun  intensive investigations  and audits  of  health care  providers to
determine whether  the  providers  are overcharging  for  medical  services  and
 
                                       3
<PAGE>
procedures   for  Medicare  and  Medicaid  patients.   In  cases  in  which  the
overcharging is  deemed intentional  and meets  other criteria,  the federal  or
state  government may seek criminal,  civil, or administrative sanctions against
health care providers.  This could  result in  exclusion from  the Medicare  and
Medicaid  programs and could  result in suspension  or debarment from government
contracts. Any such exclusion, suspension or debarment of the Company could have
a material adverse effect upon the Company's business.
 
    UNCERTAINTY RELATING  TO  HEALTH  CARE  REFORM.    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,  there  are  currently   numerous
initiatives  on the federal and state levels for comprehensive reforms affecting
the payment for and availability of health care services, including a number  of
proposals  that  would  significantly  limit  reimbursement  under  Medicare and
Medicaid. It is not clear at this  time what proposals, if any, will be  adopted
or, if adopted, what effect such proposals would have on the Company's business.
There  can  be  no  assurance  that currently  proposed  or  future  health care
legislation  or  other  changes  in  the  administration  or  interpretation  of
governmental  health  care  programs will  not  have  an adverse  effect  on the
Company.
 
DEPENDENCE ON CERTAIN CONTRACTS
 
    For the year ended April 30, 1996, and for the nine months ended January 31,
1997, 37% and 30%, respectively, of the Company's revenues, and an even  greater
percentage  of the  Company's gross  profits, were  derived from  two contracts.
These contracts are with the District  of Columbia Department of Human  Services
("DCDHS")  (concerning the Company's  Medicaid HMO in  the District of Columbia)
and with Medigroup, Inc.,  a wholly owned subsidiary  of BCBSNJ (concerning  the
development  and management of  ten integrated health  care delivery networks in
New Jersey),  and accounted  for  28% and  9%,  respectively, of  the  Company's
revenues  in fiscal 1996. For  the nine months ended  January 31, 1997, revenues
derived from  these  contracts represented  21%  and 9%,  respectively,  of  the
Company's  revenue.  As  described  below,  in  conjunction  with  the Company's
purchase  of  the  ten  primary  care  facilities  from  BCBSNJ,  the  Company's
relationship  with BCBSNS was substantially restructured. The loss of either the
DCDHS contract or the new BCBSNJ  contract would have a material adverse  effect
on the Company's business, financial condition and results of operations.
 
    On  February  28,  1997, the  Company  and  a real  estate  investment trust
subsidiary in which the Company owns  a minority interest (the "REIT")  acquired
ten  primary care facilities located throughout  New Jersey formerly operated by
BCBSNJ. The ten health  centers were originally designed,  built and managed  by
the  Company  under a  management agreement  with  BCBSNJ. Under  the management
agreement, the Company recruited physicians and other center staff, developed an
integrated referral network  of medical and  surgical specialists, and  designed
the  utilization, case management  and quality assurance  systems for the health
centers.
 
    The total  consideration  paid  by  the Company  and  the  REIT  to  BCBSNJ,
approximately  $35  million, was  determined  through arms'  length negotiations
between the  Company and  BCBSNJ. Of  the $35  million received  by BCBSNJ,  $22
million  was paid by the REIT and the balance was paid by the Company, including
$10.6 million  in cash  plus 90,000  shares of  the Company's  common stock.  In
addition,  in connection with  the transaction, the Company  made a $0.9 million
capital contribution  to  the REIT  and  advanced  the REIT  an  additional  $18
million,  including $16  million in short-term  secured loans and  $2 million in
long-term secured loans,  until permanent financing  is obtained. The  Company's
portion  of the cash consideration paid to BCBSNJ and the amounts contributed or
advanced to the REIT were obtained from a combination of cash on hand, equipment
lease financing and borrowings on its bank line of credit.
 
    The Company  intends to  use the  health  centers as  the cornerstone  of  a
provider  sponsored integrated health care delivery  network to be operated on a
non-exclusive basis for BCBSNJ,  and other third  party payors, including  HMOs.
The integrated health care delivery network will operate
 
                                       4
<PAGE>
under  the name Pinnacle Health Enterprises  and resemble other provider service
networks managed by  the Company  in Connecticut  and Georgia,  which align  the
Company with local hospital and physical partners.
 
    In  addition, the physicians  previously employed at  the health centers are
now employed  by  a professional  medical  group affiliated  with  the  Company.
Concurrent  with the  purchase agreement the  Company and BCBSNJ  entered into a
network services agreement pursuant to which the Company provides certain health
care services to enrolled BCBSNJ  beneficiaries through global capitation  based
on  market rates.  Under the network  services agreement,  BCBSNJ has guaranteed
certain global capitation payments to the Company over a three year period.
 
    In connection with the acquisition,  PHP's management agreement with  BCBSNJ
was  terminated and BCBSNJ  paid PHP for  all outstanding receivables, including
retroactive net capitation  payments (less  operating expenses)  for the  period
prior  to February 28,  1997 and after July  1, 1996, as  if the transaction had
been completed on that date.
 
    The Company's  accounts receivable  as  of January  31, 1997  include  gross
amounts  due from the DCDHS and the United States Department of Health and Human
Services totalling  $17.6  million  related  to  the  cost  settlement  for  the
three-year  contract period  ended September 30,  1994, and related  to the cost
settlement for the  contract period beginning  October 1, 1994.  In the  quarter
ending  January  31, 1997,  the Company  established a  reserve of  $9.8 million
against its medicaid  receivable from  DCDHS, principally  relating to  services
provided during the period 1992 through 1994. The Company cannot predict when or
whether  any of the unreserved amounts will  be paid. The failure of the Company
to collect such amounts  would have a material  adverse effect on the  Company's
business, financial condition and results of operations.
 
CAPITATED NATURE OF REVENUE
 
    The Company provides a portion of its services on a capitated basis, and the
Company  intends to negotiate additional  capitated agreements with managed care
organizations or assume such contracts  in connection with its affiliation  with
primary  care practices. Such contracts, typically referred to as "risk sharing"
contracts, are  arrangements  between  the  Company  and  another  managed  care
organization  under  which the  Company agrees  to  provide certain  health care
services, as required by members of such managed care organization, in  exchange
for  a fixed fee per member per  month. Under these contracts, the Company bears
the risk that the cost of the services it is required to provide will exceed the
fixed fees it is entitled to receive.  In order for such risk sharing  contracts
to  be  profitable for  the  Company, the  Company  must effectively  manage the
utilization rate of  primary care  services, specialty  physician services,  and
hospital  services delivered to members of  the managed care organization. There
can be no assurance  that the Company will  receive fees under such  shared-risk
arrangements  which  will permit  it to  recover  the costs  of the  health care
services it will be required to provide.
 
DEPENDENCE ON PRIMARY CARE PHYSICIANS
 
    Primary care  physicians are  a  key operating  component of  the  Company's
integrated  health care  delivery networks.  The Company  competes for exclusive
primary care physician affiliations with  a variety of networks including  group
practices, IPAs, HMOs, practice management companies and hospitals. Most primary
care  physicians have traditionally  practiced independently or  in small single
specialty groups. The competitive and operational disadvantages to the physician
of this type of  practice structure have compelled  many of these physicians  to
evaluate  alternatives. The process  of negotiating these  affiliations is often
competitive, complex and  time consuming.  There can  be no  assurance that  the
Company  will continue  to be  able to identify  and secure  affiliations with a
sufficient number of primary  care physicians to  operate its integrated  health
care delivery networks effectively.
 
                                       5
<PAGE>
LIMITATIONS ON REIMBURSEMENT
 
    A  major  portion of  the  Company's revenues  is  derived from  third party
payors, such as governmental programs, private insurance plans and managed  care
organizations.  In particular, for  the year ended  April 30, 1996  and the nine
months ended January 31, 1997, approximately  29% and 28%, respectively, of  the
Company's  revenues were derived from the Medicaid program, a cooperative state-
federal program for medical assistance to  the needy. Reflecting a trend in  the
health  care  industry, third  party  payors increasingly  are  negotiating with
health care providers  such as  the Company  concerning the  prices charged  for
medical services, with the goal of lowering reimbursement and utilization rates.
There can be no assurance that any future reduction in reimbursement rates would
be  offset through enhanced operating efficiencies, or that any such enhancement
of operating  efficiencies  would  occur.  Third  party  payors  may  also  deny
reimbursement if they determine that a treatment was not performed in accordance
with  the  cost-effective  treatment  methods established  by  such  payors, was
experimental, or  for  other  reasons. In  addition,  funding  for  governmental
programs, such as Medicaid, is under increased scrutiny.
 
    Congress  continues to make  cutbacks in the  Medicare and Medicaid programs
following its  failure  to enact  a  budget reconciliation  bill  providing  for
reductions  in  the rate  of  spending increases  in  the Medicare  and Medicaid
programs. These cutbacks, budgetary  constraints at both  the federal and  state
levels,  and increasing  public and private  sector pressures  to contain health
care costs  are  likely  to  continue  to  lead  to  significant  reductions  in
government  and other third party reimbursements for medical charges which could
adversely affect the Company.
 
MANAGEMENT INFORMATION SYSTEMS
    The Company's management information systems are critical to its ability  to
manage  care efficiently and to be competitive in the market. The Company relies
on these systems to support practice operations and to facilitate the management
and monitoring of clinical performance. Clinical guidelines, practice protocols,
case management  and  utilization  review  systems  are  all  essential  to  the
Company's  ability  to  secure,  and  operate  profitably  under,  capitated and
shared-risk contracts. There can be no  assurance that the Company will be  able
to refine and enhance these systems to keep them current and competitive.
 
DEPENDENCE ON GOVERNMENT CONTRACTS
    Contracts   with  various  federal,  state  and  local  government  agencies
(excluding agreements concerning the Company's  Medicaid HMO in the District  of
Columbia)  accounted for approximately 47% and 45% of the Company's revenues for
the year ended  April 30,  1996, and  the nine  months ended  January 31,  1997,
respectively.  These contracts  are obtained  primarily through  the competitive
bidding process  as  governed  by  applicable federal  and  state  statutes  and
regulations,  and generally may be modified or terminated for the convenience of
the government agency at any time during the term of the contract. Contracts are
generally awarded for a base period of less than one year and corresponding with
the government agency's fiscal year,  have two-to-four one-year renewals at  the
option  of  the government  agency, and  are subject  to appropriation  of funds
annually by the appropriate legislative body. There is, therefore, no  assurance
that  the Company will be able to retain its contracts or, if retained, that all
of such contracts will be fully funded.
 
    Under the competitive bidding process, unsuccessful bidders may protest  the
award  of a contract to  another bidder in accordance  with a government appeals
process if they believe  the award was improper.  Such protests could result  in
the  rebidding,  delay  or  loss  of  contracts.  In  addition,  contracts  with
government agencies are generally complex  in nature and subject contractors  to
extensive regulation under federal, state and local law. For example, government
contractors  are subject to  audits which can result  in adjustments to contract
costs and fees.
 
    The Company believes  that it  has complied  in all  material respects  with
applicable   government  regulations.  In  certain   circumstances  in  which  a
contractor has not complied with the terms of a contract or with regulations  or
statutes,  the contractor  may be  debarred or  suspended from  obtaining future
contracts for a specified period of time. Moreover, pursuant to recent  statutes
and  regulations,  a  suspension  or  debarment  from  obtaining  future federal
contracts will also result in a reciprocal
 
                                       6
<PAGE>
suspension or debarment from participation in non-procurement federal  programs,
such  as Medicare, Medicaid, and other federally-funded grant programs. Any such
suspension or debarment of the Company could have a material adverse effect upon
the Company's business.
 
DEPENDENCE ON KEY PERSONNEL
    The Company  is highly  dependent on  the skill  and efforts  of its  senior
management.  The loss of  key management personnel or  the inability to attract,
retain and motivate sufficient numbers  of qualified management personnel  could
adversely affect the Company's business.
 
COMPETITION
 
    The managed care industry is highly competitive and is subject to continuing
changes  in how services are  provided and how providers  are selected and paid.
Increased enrollment in prepaid health care  plans due to health care reform  or
for  other reasons, increased participation by physicians in group practices and
other factors may attract new entrants into the managed care industry and result
in increased competition for the  Company. Certain of the Company's  competitors
are  significantly larger  and better  capitalized, provide  a wider  variety of
services, may  have  greater  experience in  providing  health  care  management
services and may have longer established relationships with payors.
 
EXPOSURE TO PROFESSIONAL LIABILITY
    Due to the nature of the Company's business, there are asserted from time to
time  medical malpractice lawsuits and other claims against the Company, some of
which are currently pending, which subjects the Company to the attendant risk of
substantial damage awards. The most significant source of potential liability in
this regard  is the  negligence  of physicians  employed  or contracted  by  the
Company.  To the  extent such  physicians are employees  of the  Company or were
regarded as  agents of  the Company  in the  practice of  medicine, the  Company
would,  in most instances, be held liable for their negligence. In addition, the
Company could be found in certain instances to have been negligent in performing
its management  services  under  contractual arrangements,  even  if  no  agency
relationship  with  the  physician  were  found to  exist.  In  some  cases, the
Company's contracts with hospitals and third party payors require the Company to
indemnify such  other  parties  for  losses resulting  from  the  negligence  of
physicians who were employed or managed by or affiliated with the Company.
 
    The  Company  maintains professional  and general  liability insurance  on a
claims made  basis  in  amounts  deemed  appropriate  by  management,  based  on
historical  claims and  the nature and  risks of  its business. There  can be no
assurances, however, that an existing or future claim or claims will not  exceed
the limits of available insurance coverage, that any insurer will remain solvent
and  able to  meet its  obligations to  provide coverage  for any  such claim or
claims or that  such coverage will  continue to be  available or available  with
sufficient limits and at a reasonable cost to adequately and economically insure
the Company's operations in the future. A judgment against the Company in excess
of such coverage could have a material adverse effect on the Company.
 
HISTORICAL LOSSES
    The  Company reported net losses of $3,756,000 and $9,334,000 for the fiscal
years ended April 30, 1993 and 1994, respectively, and a net loss of  $5,142,000
for  the nine months ended  January 31, 1997. There can  be no assurance that it
will operate profitably in the future, or have earnings or cash flow  sufficient
to  comply with the financial  covenants to which it is  subject or to cover its
fixed charges. As a consequence of the losses reported in fiscal 1993 and  1994,
and  the fiscal period ended January 31, 1997, the Company failed to comply with
certain financial covenants  under its  credit agreement.  The Company  obtained
waivers  for such noncompliance  and the Company's  bank modified the applicable
financial covenants. In the  future, any failure by  the Company to comply  with
the financial covenants contained in its credit agreement (or in any replacement
credit  facility) could result in a default under such facility which could have
a material adverse  effect on  the Company's business,  financial condition  and
results of operations.
 
SUBSTANTIAL INDEBTEDNESS
    The  Company's indebtedness is substantial  in relation to its stockholders'
equity. At January 31, 1997, the Company's total long-term debt, net of  current
portion, accounted for 72% of its total capitalization.
 
                                       7

POSSIBLE VOLATILITY OF STOCK PRICE
    The  market  price of  the Common  Stock  has experienced  a high  degree of
volatility. There can be no assurance that such volatility will not continue  or
become  more pronounced. In addition, recently the stock market has experienced,
and is  likely  to  experience  in the  future,  significant  price  and  volume
fluctuations  which could adversely affect the  market price of the Common Stock
without regard to the operating performance of the Company. The Company believes
that factors such  as quarterly  fluctuations in  the financial  results of  the
Company  or its competitors and general  conditions in the industry, the overall
economy and the financial markets could cause  the price of the Common Stock  to
fluctuate substantially.
 
CONTROL BY MANAGEMENT AND CERTAIN STOCKHOLDERS
    Certain  of  the  Company's  executive officers  and  directors  and related
entities (the "Shareholders") currently hold an aggregate of approximately 22.6%
of the  outstanding  Common Stock  (10.8%  including shares  issuable  upon  the
exercise  of options  or the conversion  of convertible securities  held by such
persons and  exercisable or  convertible  within 60  days)  and may  exercise  a
controlling  influence over  the outcome of  matters submitted  to the Company's
stockholders for approval. In addition, pursuant  to the terms of an  Employment
Agreement  (the "Employment  Agreement") entered  into as  of February  24, 1997
between the Company and  Charles H. Robbins, the  Company's former Chairman  and
Chief Executive Officer, Mr. Robbins and his wife, Ellen Robbins, agreed to vote
Common  Stock  beneficially  owned  by  them, at  their  option,  either  (i) in
accordance with the recommendation of the  Board of Directors of the Company  or
(ii)  pro  rata  in the  same  manner and  proportion  that votes  of  the other
stockholders of the Company have been cast.  The Robbins have agreed to vote  in
such  a manner until  the earlier of  (i) January 31,  1999 or (ii)  a Change of
Control (as defined  in the  Employment Agreement). Including  the Common  Stock
beneficially  owned by the  Robbins, the Shareholders have  voting control of an
aggregate 37.2% of the Outstanding Common Stock (14.5% including shares issuable
upon the exercise of options or the conversion of convertible securities held by
the Shareholders and the Robbins and exercisable or convertible within 60 days).
As  a  result,   such  executive  officers,   directors  and  related   entities
collectively  may have the power to delay,  defer or prevent a change in control
of the Company.
 
ANTI-TAKEOVER EFFECT OF DELAWARE LAW AND CHARTER AND BY-LAW PROVISIONS
    Certain provisions of  the Company's certificate  of incorporation,  by-laws
and Delaware law could, together or separately, discourage potential acquisition
proposals,  delay or prevent  a change in  control of the  Company and limit the
price that certain investors might be willing to pay in the future for shares of
the Common Stock. These provisions include a classified Board of Directors,  the
ability  of the  Board of Directors  to authorize the  issuance, without further
stockholder approval, of preferred stock with rights and privileges which  could
be  senior to the Common Stock, elimination of the stockholders' ability to take
any action  without  a meeting,  and  establishment of  certain  advance  notice
procedures  for  nomination  of candidates  for  election as  directors  and for
stockholder proposals to be considered  at stockholders' meetings. In  addition,
the  Company has distributed  preferred stock purchase  rights which could cause
substantial dilution to a person or group that attempts to acquire a controlling
interest in the  Company. The  Company is  also subject  to Section  203 of  the
Delaware   General  Corporation  Laws  which,  subject  to  certain  exceptions,
prohibits a  Delaware corporation  from engaging  in  any of  a broad  range  of
business  combinations with any  "interested stockholder" for  a period of three
years  following  the   date  that  such   stockholder  became  an   "interested
stockholder." See "Description of Capital Stock."
 
RISKS ASSOCIATED WITH "FORWARD-LOOKING" STATEMENTS
    This  Prospectus contains  and incorporates by  reference certain statements
that are "forward-looking statements" within the  meaning of Section 27A of  the
Securities  Act and Section  21E of the Exchange  Act. Those statements include,
among other  things, the  discussions  of the  Company's business  strategy  and
expectations  concerning  the  Company's  market  position,  future  operations,
margins, profitability, liquidity and capital resources. Investors in the Common
Stock  offered  hereby  are  cautioned  that  reliance  on  any  forward-looking
statement  involves  risks  and  uncertainties, and  that  although  the Company
believes that the assumptions on which the forward-looking statements  contained
herein  are based  are reasonable,  any of those  assumptions could  prove to be
inaccurate, and
 
                                       8
<PAGE>
as a  result, the  forward-looking statements  based on  those assumptions  also
could  be  incorrect. The  uncertainties  in this  regard  include, but  are not
limited to, those identified  in the risk factors  discussed above. In light  of
these  and  other uncertainties,  the inclusion  of a  forward-looking statement
herein should  not be  regarded as  a  representation by  the Company  that  the
Company's plans and objectives will be achieved.
 
                                  THE COMPANY
 
    PHP  Healthcare Corporation ("PHP" or  the "Company") develops, consolidates

    The  Committee acts as manager of, and  not trustee of, the Plan. Members of
the Committee  or the  Board  of Directors  receive  no compensation  for  their
services  in connection with their administration of the Plan. As of the date of
this Prospectus, the  members of the  Board of Directors  and the Committee  are
listed  in the  Company's Annual  Report on  Form 10-K.  Requests for additional
information should be directed  to Anthony M.  Picini, Executive Vice  President
and  Chief Financial  Officer, PHP  Healthcare Corporation,  11440 Commerce Park
Drive, Reston, VA, 20191.
 
ERISA; INTERNAL REVENUE CODE
 
    The Plan is not  subject to the Employee  Retirement Income Security Act  of
1974 ("ERISA") and is not qualified under Section 401(a) of the Internal Revenue
Code  of 1986, as amended (the "Code").  Options granted under the Plan may only
be nonqualified stock  options. See  "Certain United States  Federal Income  Tax
Consequences"  below for information concerning the tax treatment of Options and
the Shares issued upon the exercise thereof.
 
ELIGIBILITY
 
    The Plan provides  that Options  may be  granted to  any director,  officer,
employee,  consultant or  advisor of the  Company, any  Subsidiary, Affiliate or
Associate of  the  Company  or to  any  person  with whom  the  Company  or  any
Subsidiary,  Affiliate  or  Associate  has a  management  or  services agreement
including, without  limitation, (i)  any duly  licensed doctor  of medicine  who
provides  health  care services  in  any health  care  network, plan  or product
sponsored or  administered  by  the  Company or  any  Subsidiary,  Affiliate  or
Associate,  or (ii) any professional medical corporation, the employees of which
include a duly licensed doctor of medicine who provides health care services  in
any health care network plan or product sponsored or administered by the Company
or  any Subsidiary, Affiliate or  Associate ("Eligible Person"). Notwithstanding
the foregoing,  the term  "Eligible Person"  shall not  include any  officer  or
director  of the Company who is subject  to reporting under Section 16(a) of the
Exchange Act.
 
    Subject to  the  terms and  conditions  of  the Plan,  the  Committee  shall
determine  the Eligible Persons to whom Options  shall be granted under the Plan
and the  number of  such Options  to be  granted, and  prescribe the  terms  and
conditions  of each such Option, including  the purchase price per Share subject
to each Option. The  Plan does not  provide for a maximum  or minimum number  of
shares of Common Stock that may be granted under Options to any Eligible Person.
 
TERMS AND CONDITIONS OF OPTIONS
 
    Each  grant of an Option under the Plan shall be evidenced by a Stock Option
Agreement ("Agreement") between the Optionee and the Company, and is subject  to
the following additional terms and conditions:
 
    PURCHASE  PRICE.   The purchase  price per  Share under  each Option granted
under the Plan shall be determined by  the Committee and shall not be less  than
the par value of a Share on the date the Option is granted.
 
    MAXIMUM  DURATION.  Options granted under the Plan shall be for such term as
the Committee shall determine, provided that an Option shall not be  exercisable
after the expiration of ten (10) years from the date it is granted.
 
    VESTING.   Each Option shall become  exercisable in such installments and at
such times as may be designated by the Committee and set forth in the  Agreement
and  may  be  exercised  in  whole  or  in  part,  at  any  time  after becoming
exercisable, but not later than the  date the Option expires. The Committee  may
accelerate the exercisability of any Option or portion thereof at any time.
 
    MODIFICATION.  The Committee may amend or modify any Agreement in any manner
consistent  with the  terms of  the Plan,  provided that  no modification  of an
Option may adversely alter or impair any rights or obligations under the  Option
without the Optionee's consent.
 
    NON-TRANSFERABILITY.  No Option granted under the Plan shall be transferable
by  the Optionee  to whom  granted except  by will  or the  laws of  descent and
distribution, and an Option may be exercised
 
                                       10
<PAGE>
during the lifetime of such Optionee only by the Optionee or his or her guardian
or legal representative. The  terms of such Option  shall be final, binding  and
conclusive   upon  the  beneficiaries,   executors,  administrators,  heirs  and
successors of the Optionee.
 
    METHOD OF EXERCISE.   The  exercise of  an Option shall  be made  only by  a
written notice delivered in person or by mail to the Secretary of the Company at
the  Company's principal executive office, specifying the number of shares to be
purchased and accompanied by payment  therefor and otherwise in accordance  with
the  Agreement pursuant to which the Option  was granted. The purchase price for
any Shares purchased pursuant to the exercise of an Option shall be paid in full
in cash upon such exercise.  Notwithstanding the foregoing, the Committee  shall
have  the discretion to determine at the time  of grant of each Option or at any
later date (up to and including the  date of exercise) that the form of  payment
acceptable  in respect of the  exercise of such Option  may consist of either of
the following (or  any combination thereof):  (i) cash or  (ii) the transfer  of
Shares  to  the Company  upon such  terms  and conditions  as determined  by the
Committee. Any Shares  transferred to  the Company  as payment  of the  purchase
price  under an  Option shall be  valued at their  Fair Market Value  on the day
preceding the  date of  exercise of  such Option.  In addition,  Options may  be
exercised  through a registered broker-dealer pursuant to such cashless exercise
procedures (other than Share withholding) which  are, from time to time,  deemed
acceptable  by the  Committee. No  fractional Shares  (or cash  in lieu thereof)
shall be issued upon exercise of an Option and the number of Shares that may  be
purchased upon exercise shall be rounded to the nearest number of whole Shares.
 
    RIGHTS  OF OPTIONEES.  No Optionee shall be deemed for any purpose to be the
owner of any Shares subject to any Option unless and until (i) the Option  shall
have  been exercised pursuant to the terms  thereof, (ii) the Company shall have
issued and delivered Shares to the Optionee and (iii) the Optionee's name  shall
have  been  entered as  a stockholder  of record  on the  books of  the Company.
Thereupon, the Optionee shall  have full voting,  dividend, and other  ownership
rights  with respect to such Shares, subject to such terms and conditions as may
be set forth in the applicable Agreement.
 
EFFECT OF A TERMINATION OF SERVICE
 
    The Agreement evidencing the grant of each Option shall set forth the  terms
and  conditions applicable to  such Option upon  a termination or  change in the
Optionee's status as an  Eligible Person, including a  termination or change  by
reason  of  the sale  of the  Company's interest  in any  Subsidiary, Affiliate,
Associate or Division, which shall be  as the Committee may, in its  discretion,
determine at the time the Option is granted or thereafter.
 
EFFECT OF CERTAIN TRANSACTIONS
 
    Except  as  otherwise provided  in an  Agreement,  in the  event of  (i) the
liquidation or dissolution of the Company  or (ii) a merger or consolidation  of
the  Company (a "Transaction"), the Plan and the Options issued thereunder shall
continue in  effect  in accordance  with  their respective  terms,  except  that
following a Transaction each Optionee shall be entitled to receive in respect of
each Share subject to any outstanding Options, upon exercise of any Options, the
same   number  and  kind   of  stock,  securities,   cash,  property,  or  other
consideration that  each  holder of  a  Share was  entitled  to receive  in  the
Transaction  in  respect  of  a  Share;  PROVIDED,  HOWEVER,  that  such  stock,
securities, cash, property, or other  consideration shall remain subject to  all
of  the conditions, restrictions and  performance criteria which were applicable
to the Options prior to such Transaction.
 
WITHHOLDING OF TAXES
 
    At such times as  an Optionee recognizes taxable  income in connection  with
the  receipt of Shares or cash under  the Plan (a "Taxable Event"), the Optionee
shall pay to the Company an amount equal to the federal, state and local  income
taxes  and other amounts as may be required by law to be withheld by the Company
in connection with  the Taxable  Event (the  "Withholding Taxes")  prior to  the
issuance,  or release from escrow,  of such Shares or  the payment of such cash.
The Company  shall have  the right  to deduct  from any  payment of  cash to  an
Optionee  an  amount  equal to  the  Withholding  Taxes in  satisfaction  of the
obligation to pay Withholding  Taxes. In satisfaction of  the obligation to  pay
 
                                       11
<PAGE>
Withholding  Taxes to  the Company,  the Optionee  may make  a written election,
which may be accepted  or rejected in  the discretion of  the Committee to  have
withheld a portion of the Shares then issuable to him or her having an aggregate
Fair Market Value equal to the Withholding Taxes.
 
ADJUSTMENT OF SHARES UPON CHANGES IN CAPITALIZATION OR REORGANIZATION
 
    In  the event of any Change  in Capitalization the Committee shall determine
the appropriate adjustments,  if any,  to the (i)  maximum number  and class  of
Shares or other stock or securities with respect to which Options may be granted
under  the  Plan and  (ii) the  number and  class  of Shares  or other  stock or
securities which are subject to outstanding  Options granted under the Plan  and
the  purchase price  therefor, if applicable.  A Change  in Capitalization could
result  from  a   reclassification,  recapitalization,  merger,   consolidation,
reorganization,   spin-off,  split-up,   issuance  of  warrants   or  rights  or
debentures, stock dividend, stock split  or reverse stock split, cash  dividend,
property  dividend,  combination or  exchange of  shares, repurchase  of shares,
change in corporate structure or similar event.
 
TERMINATION AND AMENDMENT OF THE PLAN
 
    The Plan shall terminate on the  day preceding the tenth anniversary of  the
date  of its adoption by the Board and  no Option may be granted thereafter. The
Board may sooner terminate the  Plan and may at any  time and from time to  time
amend,  modify or suspend the Plan;  PROVIDED, HOWEVER, that: no such amendment,
modification, suspension  or termination  shall impair  or adversely  alter  any
Options  theretofore  granted under  the Plan,  except with  the consent  of the
Optionee, nor  shall  any  amendment, modification,  suspension  or  termination
deprive  any Optionee of any Shares which he or she may have acquired through or
as a result of the Plan.
 
                          DESCRIPTION OF CAPITAL STOCK
 
    The Company's  authorized capital  stock consists  of 25,000,000  shares  of
Common  Stock, par value $.01 per share,  and 500,000 shares of Preferred Stock,
par value $.01 per share. No shares of Preferred Stock are outstanding.  Certain
Preferred  Stock  Purchase  Rights  were  distributed  pursuant  to  a  dividend
distribution declared April 10, 1992, and 50,000 shares of Preferred Stock  were
designated  and reserved  as Series A  Junior Participating  Preferred Stock for
issuance upon exercise of such rights. As of January 31, 1997, 11,014,444 shares
of Common Stock (including  88,572 shares held in  escrow) were outstanding  and
held by approximately 950 shareholders of record.
 
COMMON STOCK
 
    Subject  to the prior rights  of any shares of  Preferred Stock which may be
issued in the future, the  holders of the Common  Stock are entitled to  receive
dividends  as and when declared  by the Board of  Directors out of funds legally
available for  dividends,  and, in  the  event of  liquidation,  dissolution  or
winding  up  of the  Company, to  share  ratably in  all assets  remaining after
payment of liabilities. The holders of the Common Stock are entitled to one vote
for each share of Common Stock held of record on all matters submitted to a vote
of shareholders. Since  holders of Common  Stock do not  have cumulative  voting
rights,  holders of  more than  50% of  the outstanding  shares of  Common Stock
present and voting at an annual meeting  at which a quorum is present can  elect
all  the directors of the Company to be  elected at such meeting. The holders of
Common Stock have no preemptive rights or conversion rights and are not  subject
to  further calls  or assessments  by the  Company. There  are no  redemption or
sinking fund provisions applicable to the Common Stock.
 
    The Transfer Agent for the Company's Common Stock is The Bank of New York.
 
PREFERRED STOCK
 
    The Board of Directors is authorized to issue shares of Preferred Stock from
time to time  in one  or more  classes or  series and  to fix  by resolution  or
resolutions  (without further stockholder action) the voting rights, if any, and
the designations, preferences  and relative, participating,  optional and  other
special  rights, and  the qualifications, limitations  and restrictions thereof,
including, without limitation,  the dividend rights,  conversion rights,  rights
and terms of redemption (including sinking fund
 
                                       12
<PAGE>
provisions)  and liquidation rights  of each such class  or series. In addition,
the  Board  of  Directors  is  empowered  to  determine  the  number  of  shares
constituting each class and series of Preferred Stock and, subject to compliance
with  applicable law, to increase or decrease  the number of shares of each such
class or series. The Board of Directors may, without shareholder approval, issue
Preferred Stock with voting and  conversion rights which could adversely  affect
the voting power of holders of Common Stock.
 
PREFERRED STOCK PURCHASE RIGHTS
 
    The  description  of  certain Preferred  Stock  Purchase  Rights distributed
pursuant to a dividend distribution declared by the Company's Board of Directors
on April 10, 1992, and of the shares of Series A Junior Participating  Preferred
Stock  reserved for  issuance upon exercise  of such Rights,  is incorporated by
reference to Item 1 of the Company's Form 8-A, dated April 10, 1992, filed  with
the Securities and Exchange Commission on April 13, 1992.
 
    The  Preferred Stock Purchase Rights have certain anti-takeover effects. The
Rights will cause  substantial dilution to  a person or  group that attempts  to
acquire  the Company without  conditioning the offer on  a substantial number of
the Rights being acquired.  The Rights should not  interfere with any merger  or
other  business combination approved by the  Board of Directors since the Rights
may be redeemed by the Company.
 
CERTAIN PROVISIONS OF THE COMPANY'S CERTIFICATE AND BY-LAWS
 
    The Company's  Restated  Certificate of  Incorporation  (the  "Certificate")
provides  that the  Board of  Directors consists  of three  classes of directors
serving for staggered three-year terms. As a result, one-third of the  Company's
Board  of Directors  will be elected  each year. The  classified board provision
could prevent a  party who  acquires control of  a majority  of the  outstanding
voting  stock of the  Company from obtaining  control of the  Board of Directors
until the second  annual stockholders  meeting following the  date the  acquirer
obtains  the controlling interest. Subject to the rights of holders of Preferred
Stock of the Company, any vacancy on  the Board of Directors may be filled  only
by the remaining directors then in office.
 
    The  Company has 500,000 authorized and  unissued shares of Preferred Stock.
The Certificate  grants the  Board of  Directors broad  power to  establish  the
designations,  powers, preferences and rights of  any series of Preferred Stock.
Such stock  could be  used by  the Board  of Directors  for defensive  purposes,
including  its  issuance or  sale to  third parties  or use  in recapitalization
transactions.
 
    In order for a stockholder to  nominate a candidate for director, under  the
Company's  By-laws, timely notice of the nomination must be given to the Company
in advance of the meeting. Such notice  must be given in respect to an  election
to be held at an annual meeting of stockholders not less than 90 days before the
anniversary  of the immediately  preceding annual meeting, and  must be given in
respect to an election to be held at a special meeting of stockholders within 10
days after the notice of the  meeting is given to stockholders. The  stockholder
filing  the notice  of nomination  must describe  various matters  regarding the
nominee, including  such information  as name,  address, occupation  and  shares
held.
 
    In  order  for  a  stockholder  to bring  other  business  before  an annual
stockholder meeting, timely notice must be received by the Company not less than
60 days nor more than 90 days before the meeting (but if the Company gives  less
than  70 days notice of the meeting, then such notice must be received within 10
days after the notice of the meeting is mailed or other public disclosure of the
meeting is  made).  Such notice  must  include  a description  of  the  proposed
business, the reasons therefore, and other specified matters.
 
    Under  the By-laws, special  meetings of stockholders may  be called only by
the Board of Directors or the President of the Company, and may not be called by
stockholders. In addition, the Certificate provides that any action required  or
permitted to be taken by the stockholders of the Company at an annual or special
meeting of stockholders must be effected at a duly called meeting and may not be
taken or effected by a written consent of the stockholders in lieu thereof.
 
                                       13
<PAGE>
    The  By-laws may be amended by the Board of Directors or by affirmative vote
of the holders of two-thirds of the stock issued and outstanding and entitled to
vote thereon.  Certain  provisions  of  the  Certificate,  including  provisions
concerning  the classified Board of Directors and the ability of stockholders to
take action only at an  annual or special meeting  of stockholders, may only  be
amended by the affirmative vote of the holders of two-thirds of the stock issued
and outstanding and entitled to vote thereon. The foregoing summary is qualified
in  its entirety by reference to the  full text of the Company's Certificate and
By-laws.
 
    These provisions  are  designed  in  part to  make  it  more  difficult  and
time-consuming  to  obtain majority  control of  the Board  of Directors  of the
Company or otherwise to bring a  matter before stockholders without the  Board's
consent,  and thus  reduce the  vulnerability of  the Company  to an unsolicited
takeover proposal.  These  provisions are  designed  to enable  the  Company  to
develop  its business in a  manner which will foster  its long-term growth, with
the threat of a takeover not deemed by  the Board to be in the best interest  of
the Company and its stockholders and the potential disruption entailed by such a
threat  reduced to the  extent practicable. On the  other hand, these provisions
may have  an adverse  effect on  the ability  of stockholders  to influence  the
governance  of  the  Company and  the  possibility of  stockholders  receiving a
premium above market price for their securities from a potential acquiror who is
unfriendly to management.
 
DELAWARE GENERAL CORPORATION LAW SECTION 203
 
    As a corporation  organized under  the laws of  the State  of Delaware,  the
Company  is subject to Section 203 of the Delaware General Corporation Law which
restricts certain business combinations between  the Company and an  "interested
stockholder"  (in general,  a stockholder  owning 15%  or more  of the Company's
outstanding voting stock) or its affiliates or associates for a period of  three
years  following  the  date  on which  the  stockholder  becomes  an "interested
stockholder." The  restrictions do  not  apply if  (i)  prior to  an  interested
stockholder  becoming such, the Board of  Directors approves either the business
combination or the transaction  in which the  stockholder becomes an  interested
stockholder  (ii)  upon  consummation of  the  transaction in  which  any person
becomes an interested stockholder, such interested stockholder owns at least 85%
of the  voting stock  of the  Company outstanding  at the  time the  transaction
commences  (excluding shares owned by certain employee stock ownership plans and
persons who are  both directors  and officers  of the  Company) or  (iii) on  or
subsequent  to the  date an  interested stockholder  becomes such,  the business
combination is both  approved by  the Board of  Directors and  authorized at  an
annual or special meeting of the Company's stockholders, not by written consent,
by  the affirmative vote of at least 66 2/3% of the outstanding voting stock not
owned by the interested stockholders.
 
                              SELLING STOCKHOLDERS
 
    Medigroup beneficially owns 90,000 shares of Common Stock, all of which  are
being registered for sale pursuant to this Prospectus. The Company has agreed to
use  its best efforts to keep this  Prospectus effective as to such shares until
June 30, 1997. In the event that the Blue Cross Shares have not been sold  prior
to  June 30,  1997, the  Purchase Agreement  provides that  until July  10, 1997
Medigroup may  require the  Company  to purchase,  or  the Company  may  require
Medigroup  to sell, the Blue Cross Shares for $2,400,000 in cash (or any portion
of such Shares for a pro rata portion of the aggregate price). Medigroup has not
had a material relationship with the  Company within the past three years  other
than  as a result of  the ownership of the  Blue Cross Shares. Because Medigroup
may offer all  or some of  the Shares which  it holds pursuant  to the  offering
contemplated  by this Prospectus, and because there are currently no agreements,
arrangements or understandings with respect to the sale of any of the Blue Cross
Shares, no estimate can be given as to the number of Blue Cross Shares that will
be held by Medigroup after completion of this offering.
 
    Charles H. Robbins  ceased to be  an executive officer  and director of  the
Company  effective as of January  31, 1997, but will  continue as an employee of
the Company until January  31, 1998, unless terminated  earlier pursuant to  the
terms  of  the Employment  Agreement.  Mr. Robbins  beneficially  owns 1,710,076
shares of Common Stock, including 526,667  shares which Mr. Robbins can  acquire
 
                                       14
<PAGE>
upon  the exercise of  options granted by  the Company pursuant  to stock option
agreements. The 1,710,076 shares do not, however, include shares owned by  Ellen
E.  Robbins, individually  and as  trustee, described  below, or  139,000 shares
beneficially owned by Charles H. Robbins' son, Charles B. Robbins. The 1,710,076
shares beneficially owned by  Mr. Robbins represent  approximately 14.8% of  the
outstanding Common Stock of the Company. Pursuant to the terms of the Employment
Agreement, Mr. Robbins may require the Company to purchase 200,000 of his shares
prior  to April 30,  1997 at a price  equal to the average  closing price of the
Common Stock  for five  days preceding  the  sale (the  "Put Right").  Ellen  E.
Robbins,  individually and  as trustee  under trusts  established by  Charles H.
Robbins for the benefit of Caroline H. Robbins and Lee S. Robbins,  beneficially
owns  300,000 shares of Common Stock,  which represent approximately 2.7% of the
outstanding Common Stock of the Company.
 
    In the aggregate, Charles H. Robbins and Ellen E. Robbins (individually  and
as  trustee) beneficially own 2,010,076 shares  of Common Stock, which represent
approximately 17.4% of the outstanding Common Stock of the Company.
 
    Pursuant to Section 3.01 of the Employment Agreement, Charles H. Robbins and
Ellen E. Robbins have agreed not  to acquire beneficial ownership of  additional
securities  of the Company  prior to the earlier  of January 31,  1999 or (ii) a
change in control of the Company.
 
    In addition, Charles  H. Robbins and  Ellen E. Robbins,  have agreed not  to
dispose of their shares of the Company prior to November 1, 1997, other than the
shares  registered by this  Prospectus, pursuant to  the Put Right  or after the
occurence of certain events as set forth in the Employment Agreement.
 
    Charles B.  Robbins  beneficially  owns  139,000  shares  of  Common  Stock,
including  39,000  shares which  he  can acquire  upon  the exercise  of options
granted by the Company pursuant to  stock option agreements. The 139,000  shares
beneficially  owned by  Charles B.  Robbins represents  1.3% of  the outstanding
Common Stock of  the Company. Until  February 24, 1997,  Charles B. Robbins  was
employed by the Company as a Senior Vice President.
 
    Because  the Robbins  Family may  offer all  or some  of the  Robbins Family
Shares pursuant to the offering contemplated by this Prospectus, and because Mr.
Robbins may exercise all or a portion  of the Put Right prior to the  completion
of  this offering, no estimate  can be given as to  the number of Robbins Family
Shares that will be held after completion of this offering.
 
                              PLAN OF DISTRIBUTION
 
OPTION SHARES
 
    The Option Shares  may be  issued from  time to  time upon  the exercise  of
Options  granted under the  Plan and the  payment in full  of the exercise price
with respect  to  such Options.  The  Option Shares  will  be sold  directly  to
Optionees  exercising  Options under  the Plan  and no  person will  receive any
commission or  other compensation  in connection  with the  sale of  the  Option
Shares.  The Company will pay all expenses incident to the offer and sale of the
Option Shares.
 
WARRANT SHARES
 
    The Warrant Shares may be issued from  time to time prior to the  expiration
of  the Warrant upon exercise of the Warrant and payment in full of the exercise
price. The Warrant Shares will be sold directly to the holder of the Warrant and
no person will receive any commission  or other compensation in connection  with
the  sale of the Warrant  Shares. The Company will  pay all expenses incident to
the offer and sale of the Warrant Shares.
 
BLUE CROSS SHARES
 
    The Blue Cross Shares may  be offered and sold from  time to time by or  for
the account of Medigroup. The Company has agreed to use its best efforts to keep
this  Prospectus effective until June 30, 1997 as to the Blue Cross Shares after
which time this Prospectus may be amended to omit
 
                                       15
<PAGE>
any portion of such shares  that have not yet been  sold. The decision to  offer
and sell the Blue Cross Shares, and the timing and amount of any offers or sales
that are made, is and will be (subject to the limitation set forth below) within
the  sole discretion of Medigroup. Any Blue Cross Shares may be offered for sale
by Medigroup on  the New  York Stock  Exchange, or  otherwise, through  brokers'
transactions  at prices then prevailing  at the time of  sale. Sales of the Blue
Cross Shares may involve: (a) block  transactions in which the broker or  dealer
so  engaged will  attempt to  sell the Blue  Cross Shares  as an  agent, but may
position and  resell a  portion of  the  block as  principal to  facilitate  the
transactions;  (b) purchases by  a broker or  dealer as principal  and resale by
such broker or dealer for its account pursuant to this Prospectus; (c)  ordinary
brokerage  transactions;  or  (d)  transactions  in  which  the  broker solicits
purchasers. Pursuant to Section 6.10 of the Purchase Agreement, Medigroup cannot
sell more than 10,000 of  the Blue Cross Shares in  any one trading day  without
having  first received the consent of the  Company. To the extent required, this
Prospectus may  be amended  and supplemented  from time  to time  to describe  a
specific   plan  of   distribution.  In   connection  with   such  transactions,
broker-dealers or other financial institutions may engage in short sales of  the
Common Stock, to the extent permitted by law, in the course of hedging positions
they  assume with Medigroup. Medigroup may also pledge Shares to a broker-dealer
or other financial institution, and, upon a default, such broker-dealer or other
financial institution, may effect sales of  the pledged shares pursuant to  this
Prospectus  (as supplemented or amended to reflect such transaction). Brokers or
dealers engaged to  sell the Blue  Cross Shares will  receive compensation  from
Medigroup  in the form of  commissions or discounts in  amounts to be negotiated
immediately prior to the sale. Any gain  realized by such brokers or dealers  on
the  sale of  the Blue Cross  Shares which they  purchase as a  principal may be
deemed to  be  compensation  to  the  brokers or  dealers  in  addition  to  any
commissions  they will  receive from  Medigroup. Brokers  or dealers  engaged by
Medigroup may arrange for other brokers  or dealers to participate. Such  broker
or  dealer and  any other  participating broker  or dealer  may be  deemed to be
"underwriters" within the  meaning of the  Securities Act and  any discounts  or
commissions  received by them or any profit on  the resale of shares by them may
be deemed to be underwriting discounts and commissions thereunder.
 
    The Company will bear  all expenses in connection  with the registration  of
the Blue Cross Shares being offered and sold by Medigroup.
 
    The  Company has advised Medigroup that,  unless granted an exemption by the
Commission from  Regulation  M  under  the Exchange  Act,  or  unless  otherwise
permitted  under  Regulation M,  Medigroup  cannot engage  in  any stabilization
activity in  connection with  the Company's  securities and  cannot bid  for  or
purchase  any  securities of  the Company  or  attempt to  induce any  person to

Act. In addition, the Company will  make copies of this Prospectus available  to
Medigroup  and Medigroup will furnish each broker or dealer engaged by Medigroup
and each  other participating  broker or  dealer the  number of  copies of  this
Prospectus required by such broker or dealer.
 
ROBBINS FAMILY SHARES
 
    The  Robbins Family Shares may  be offered and sold from  time to time by or
for the  account of  the Robbins  Family. The  decision to  offer and  sell  the
Robbins Family Shares, and the timing and amount of any offers or sales that are
made,  is and  will be  within the  sole discretion  of the  Robbins Family. Any
Robbins Family Shares may be offered for  sale by the Robbins Family on the  New
York  Stock Exchange, or otherwise,  at prices and on  terms then obtainable, at
fixed prices, at prices then  prevailing at the time  of sale, or in  negotiated
transactions  at  negotiated prices,  or  otherwise. The  Robbins  Family Shares
offered hereby may  be offered in  any manner  permitted by law,  other than  an
underwritten  public offering, including through brokers, dealers or agents, and
directly to  one or  more purchasers.  Sales of  the Robbins  Family Shares  may
involve:  (a) block transactions in  which the broker or  dealer so engaged will
attempt to sell  the Robbins Family  Shares as  an agent, but  may position  and
resell  a portion of the block as  principal to facilitate the transactions; (b)
purchases by a broker or dealer as principal and resale by such broker or dealer
for  its  account   pursuant  to   this  Prospectus;   (c)  ordinary   brokerage
transactions;    or   (d)   transactions   in    which   the   broker   solicits
 
                                       16

purchasers.  To  the  extent  required,  this  Prospectus  may  be  amended  and
supplemented  from time to time to describe  a specific plan of distribution. In
connection  with   such   transactions,  broker-dealers   or   other   financial
institutions  may  engage in  short sales  of  the Common  Stock, to  the extent
permitted by law, in the  course of hedging the  positions they assume with  the
Robbins  Family. The Robbins Family may also pledge Shares to a broker-dealer or
other financial institution, and,  upon a default,  such broker-dealer or  other
financial  institution, may effect sales of  the pledged Shares pursuant to this
Prospectus  (as  supplemented  or  amended  to  reflect  such  transaction).  In
addition,  any Shares  that qualify for  sale pursuant  to Rule 144  may be sold
under Rule  144 rather  than pursuant  to this  Prospectus. Brokers  or  dealers
engaged  to sell  the Robbins Family  Shares will receive  compensation from the
Robbins Family  in  the  form of  commissions  or  discounts in  amounts  to  be
negotiated  immediately prior to the sale. Any  gain realized by such brokers or
dealers on  the sale  of the  Robbins Family  Shares which  they purchase  as  a
principal may be deemed to be compensation to the brokers or dealers in addition
to any commissions they will receive from the Robbins Family. Brokers or dealers
engaged  by  the Robbins  Family may  arrange  for other  brokers or  dealers to
participate. Such broker or dealer and any other participating broker or  dealer
may  be deemed to be "underwriters" within the meaning of the Securities Act and
any discounts or commissions  received by them  or any profit  on the resale  of
shares  by  them may  be  deemed to  be  underwriting discounts  and commissions
thereunder.
 
    The Company will bear  all expenses in connection  with the registration  of
the Robbins Family Shares being offered and sold by the Robbins Family.
 
    The Company has advised the Robbins Family that, unless granted an exemption
by  the Commission from Regulation M under the Exchange Act, or unless otherwise
permitted  under  Regulation  M,  the  Robbins  Family  cannot  engage  in   any
stabilization  activity in connection  with the Company's  securities and cannot
bid for or  purchase any  securities of  the Company  or attempt  to induce  any
person  to purchase any of  the Company's securities other  than as permitted by
the Exchange Act. In addition, the  Company will make copies of this  Prospectus
available  to the Robbins Family and the Robbins Family will furnish each broker
or dealer engaged by the Robbins  Family and each other participating broker  or
dealer  the  number of  copies of  this  Prospectus required  by such  broker or
dealer.
 
             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
    The following  is a  general  discussion of  certain United  States  federal
income  tax considerations  relevant to  holders of  the Options  and the Option
Shares received upon  the exercise thereof.  This discussion is  based upon  the
Internal  Revenue Code of  1986, as amended  (the "Code"), Treasury Regulations,
Internal Revenue Service ("IRS") rulings, and judicial decisions now in  effect,
all  of  which  are subject  to  change  (possibly with  retroactive  effect) or
different interpretations.
 
    This discussion does  not deal  with all  aspects of  United States  federal
income  taxation that may be  relevant to holders of  the Options and the Option
Shares and does not  deal with tax  consequences arising under  the laws of  any
foreign, state or local jurisdiction. This discussion is for general information
only,  and does not purport  to address all of the  tax consequences that may be
relevant to particular purchasers in  light of their personal circumstances,  or
to  certain  types  of  purchasers  (such  as  certain  financial  institutions,
insurance companies, tax-exempt entities, dealers  in securities or persons  who
hold  the Option  Shares in connection  with a  straddle) who may  be subject to
special rules. This discussion assumes that each holder holds the Option  Shares
as capital assets.
 
    For  the purpose of this discussion, the term "United States person" means a
citizen or resident of the United  States, a corporation or partnership  created
or  organized in the United States or any  state thereof, or an estate or trust,
the income of which is includible in income for United States federal income tax
purposes regardless of its source.
 
    PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING
THE   FEDERAL,    STATE,    LOCAL    AND    FOREIGN    TAX    CONSEQUENCES    OF
 
                                       17
<PAGE>
THEIR  PARTICIPATION IN THIS OFFERING, OWNERSHIP  AND DISPOSITION OF THE OPTIONS
AND THE OPTION SHARES  RECEIVED UPON THE EXERCISE  THEREOF, AND THE EFFECT  THAT
THEIR PARTICULAR CIRCUMSTANCES MAY HAVE ON SUCH TAX CONSEQUENCES.
 
GRANT AND EXERCISE OF OPTIONS
 
    An Optionee will not be deemed to have received any income subject to tax at
the time the Option is granted.
 
    Upon  exercise  of  an Option,  the  Optionee  will recognize  an  amount of
ordinary income equal to the  excess of the fair  market value of Option  Shares
purchased  on the  date of  exercise over  the exercise  price. In  general, the
Optionee's basis in the Option Shares acquired by exercising an Option is  equal
to their fair market value at the time of the exercise. A subsequent disposition
of  such Option Shares  in a taxable  transaction will produce  capital gain (or
loss) for the Optionee equal to the difference between his or her basis and  the
sale  proceeds. Provided the Option Shares are held as a capital asset, the gain
or loss realized on such disposition will be taxed as long-term capital gain  or
loss  if the  stock was held  for more  than one year  from the  date the Option
Shares were acquired pursuant to  the exercise of the  Option. If the stock  was
held  for one year or less, such gain or loss will be short-term capital gain or
loss.
 
    The Company  is required  to  withhold any  federal,  state or  local  taxes
required  by law to be  withheld on the amount  of ordinary income recognized by
the Optionee. Under the terms of the  Plan, as set forth in the Prospectus  (see
"Description of the Plan -- Withholding Taxes"), the Optionee is required to pay
to  the Company an amount equal to the Company's withholding obligation prior to
the issuance of the Shares.
 
USING STOCK TO EXERCISE OPTIONS
 
    Special rules apply if an Optionee  already owns shares of Common Stock  and
surrenders  those  shares to  pay all  or part  of the  exercise price  under an
Option. Such a transaction is treated as a tax-free exchange with respect to the
number of new  Option Shares that  is equal to  the number of  old shares  being
surrendered.  The Optionee's basis in the new shares received for the old shares
actually surrendered in exchange therefor is the same as his or her basis in the
old shares, and the capital gain  holding period runs without interruption  from
the  date the  old shares  were acquired.  The Optionee  will recognize ordinary
income on any additional new  Option Shares received in  an amount equal to  (1)
the fair market value of the additional new Option Shares at the time of receipt
less  (2) any  cash paid by  the Optionee  in connection with  the exercise. The
Optionee's basis in the  additional Shares is  equal to any  cash paid upon  the
exercise  of the  Option plus  any amount  includible in  gross income,  and the
capital gain holding  period commences on  the date of  exercise. The effect  of
these  rules  is to  defer the  date when  any gain  in the  old shares  must be
recognized for tax purposes. Stated  differently, these rules allow an  Optionee
to  finance the  exercise of an  Option by using  shares that he  or she already
owns, without paying current tax on any unrealized appreciation in the value  of
those old shares.
 
                                 LEGAL MATTERS
 
    The  validity of the  issuance of the  Shares offered hereby  will be passed
upon for the Company by Fried, Frank, Harris, Shriver & Jacobson (a  partnership
including professional corporations), Washington, D.C. 20004.
 
                         INDEPENDENT PUBLIC ACCOUNTANTS
 
    The consolidated financial statements of the Company as of and for the years
ended  April 30, 1996 and 1995, incorporated by reference in this Prospectus and
in the  Registration Statement  from the  Company's 1996  Form 10-K,  have  been
audited  by Coopers & Lybrand  L.L.P., independent certified public accountants,
as stated  in  its  reports  incorporated by  reference  herein,  and  upon  the
authority  of said firm as experts in accounting and auditing. Coopers & Lybrand
L.L.P.'s report included in the Company's  Form 8-K/A filed on January 11,  1996
includes an explanatory paragraph regarding the
 
                                       18
<PAGE>
adjustments  described in  the first paragraph  of Note 8  to those consolidated
financial statements that were applied  to retroactively restate the 1995,  1994
and  1993 consolidated  financial statements  and footnotes  thereto included in
that Form 8-K/A for the effects of a two-for-one stock split effected as a stock
dividend in  November 1995.  With  respect to  the unaudited  interim  financial
information  as  of January  31,  1997 and  1996,  and for  the  three-month and
nine-month periods then ended incorporated  by reference in this Prospectus  and
Registration  Statement,  Coopers  & Lybrand  L.L.P.  has reported  that  it has
applied limited  procedures  in accordance  with  professional standards  for  a
review  of  such  information.  However, its  separate  report  included  in the
Company's quarterly report on Form 10-Q for the quarter ended January 31,  1997,
including  amendments  numbers  1,  2,  3 and  4  thereto,  and  incorporated by
reference herein, states that Coopers & Lybrand L.L.P did not audit and it  does
not  express an opinion on that  interim financial information. Accordingly, the
degree of reliance  on its report  on such information  should be restricted  in
light  of the limited nature of the review procedures applied. Coopers & Lybrand
L.L.P is not subject to the liability provisions of Section 11 of the Securities
Act for  its report  on  unaudited interim  financial information  because  that
report  is not a "report" or "part"  of the Prospectus or Registration Statement
prepared or certified by Coopers & Lybrand L.L.P within the meaning of  Sections
7 and 11 of the Securities Act.
 
    The  consolidated financial  statements of  the Company  for the  year ended
April 30, 1994, have  been incorporated by reference  in this Prospectus and  in
the  Registration Statement from  the Company's 1996 Form  10-K in reliance upon
the report of KPMG  Peat Marwick LLP,  independent certified public  accountants
incorporated  by  reference therein,  and  upon the  authority  of said  firm as
experts in accounting and auditing. The consolidated financial statements of the
Company for the year ended April 30, 1994, included in the Company's Form  8-K/A
filed  on January 11, 1996, but prior  to the adjustments described in the first
paragraph of Note 8 to those consolidated financial statements that were applied
to  retroactively  restate  the  1994  consolidated  financial  statements   and
footnotes  thereto for the  effects of a  two-for-one stock split  effected as a
stock dividend in  November 1995, have  been incorporated by  reference in  this
Prospectus  and in  the Registration Statement,  in reliance upon  the report of
KPMG Peat Marwick LLP, independent certified public accountants, incorporated by
reference therein, and upon the authority of said firm as experts in  accounting
and auditing.
 
    On  January 9, 1995, the Company solicited Statements of Qualifications from
several independent  accounting  firms, including  KPMG  Peat Marwick  LLP,  the
Company's public accountants for the fiscal years ended April 30, 1994 and April
30,  1993, to provide  audit services for  its consolidated financial statements
for the year ended April  30, 1995. On January 11,  1995, KPMG Peat Marwick  LLP
indicated  that it had  decided not to stand  for re-appointment and, therefore,
would not  submit  a  Statement  of  Qualifications.  The  decision  to  solicit
proposals  to perform audit services was  recommended by the Audit Committee and
approved by the Board of Directors.
 
    The audit reports  of KPMG Peat  Marwick LLP on  the Company's  consolidated
financial  statements as of  and for the  fiscal years ended  April 30, 1994 and
1993 did not contain an adverse opinion or a disclaimer of opinion, and were not
qualified or modified  as to  uncertainty, audit scope  or accounting  principle
except  with  respect  to the  Company's  adoption of  the  Financial Accounting
Standards  Board's  Statement  of   Financial  Accounting  Standards  No.   109,
Accounting  for Income Taxes, in fiscal year  ended April 30, 1994. In addition,
during fiscal year 1993 and 1994 and any subsequent interim period during  which
KPMG  Peat Marwick LLP  served as the  Company's independent public accountants,
there were  no  disagreements  with KPMG  Peat  Marwick  LLP on  any  matter  of
accounting principles, or practices, financial statement disclosure, or auditing
scope  or  procedures  which,  if  not  satisfied  to  KPMG  Peat  Marwick LLP's
satisfaction, would have caused it to make a reference to the subject matter  of
the disagreement in connection with its reports. In connection with its audit of
the  Company's consolidated financial statements for the fiscal year ended April
30, 1994, KPMG Peat Marwick LLP issued a letter relating to internal controls to
the Board of Directors that identified what KPMG Peat Marwick LLP considered  to
be  a  reportable  condition  relating to  timely  financial  reporting  and the
Company's accounting decision-making process.
 
    On March  17, 1995,  the Company  engaged  Coopers &  Lybrand L.L.P  as  the
Company's  independent  accounting  firm  to  provide  audit  services  for  the
Company's consolidated financial statements.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Subsection (a) of Section 145 of the General Corporation Law of the State of
Delaware  (the "DGCL") empowers a corporation to indemnify any person who was or
is a party or  is threatened to be  made a party to  any threatened, pending  or
completed  action, suit or proceedings,  whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or  was a director, officer, employee or agent  of
the  corporation, or is  or was serving at  the request of  the corporation as a
director, officer, employee or agent of another corporation, partnership,  joint
venture,  trust  or  other enterprise,  against  expenses  (including attorneys'
fees), judgments, fines and amounts  paid in settlement actually and  reasonably
incurred  by him in connection with such  action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed  to
the  best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
 
    Subsection (b) of Section 145 empowers a corporation to indemnify any person
who was or is  a party or is  threatened to be made  a party to any  threatened,
pending  or completed action, or  suit by or in the  right of the corporation to
procure a judgment in its favor by reason of the fact that such person acted  in
any  of the capacities  set forth above,  against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection with the defense  or
settlement  of such action or suit if he acted  in good faith and in a manner he
reasonably believed  to be  in  or not  opposed to  the  best interests  of  the
corporation, except that no indemnification may be made in respect of any claim,
issue or matter as to which such person shall have been adjudged to be liable to
the  corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon  application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.
 
    Section  145 further provides that to the  extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
action, suit or  proceeding referred to  in subsections (a)  and (b) of  Section
145,  or  in  defense  of  any  claim, issue  or  matter  therein,  he  shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in  connection therewith; that  indemnification provided for  by
Section  145 shall  not be  deemed exclusive  of any  other rights  to which the
indemnified party may be entitled; that indemnification provided for by  Section
145 shall, unless otherwise provided when authorized or ratified, continue as to
a  person who has ceased to be a  director, officer, employee or agent and shall
inure to the benefit of such  persons' heirs, executors and administrators;  and
empowers  the  corporation to  purchase and  maintain insurance  on behalf  of a
director or officer of  the corporation against  any liability asserted  against
him  and incurred by him in  any such capacity, or arising  out of his status as
such, whether  or not  the corporation  would have  the power  to indemnify  him
against such liability under Section 145.
 
                                      II-1
<PAGE>
    Article  IX  of  the  Company's  By-laws  provides  that  the  Company shall
indemnify its directors  and officers to  the fullest extent  authorized by  the
DGCL.
 
    Section  102(b)(7) of DGCL provides that  a certificate of incorporation may
contain a provision eliminating or limiting the personal liability of a director
to the  corporation or  its  stockholders for  monetary  damages for  breach  of
fiduciary duty as a director provided that such provision shall not eliminate or
limit  the liability of a director (i) for  any breach of the director's duty of
loyalty to the corporation or its  stockholders, (ii) for acts or omissions  not
in  good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which
the director derived an  improper personal benefit. Article  X of the  Company's
Certificate  of Incorporation limits  the liability of  directors to the fullest
extent permitted by Section 102(b)(7).

ITEM 17.  UNDERTAKINGS.
 
    The undersigned registrant hereby undertakes:
 
    (1) To file, during any  period in which offers or  sales are being made,  a
post-effective  amendment to this registration statement to include any material
information with respect to the plan of distribution not previously disclosed in
the registration statement  or any material  change to such  information in  the
registration statement.
 
    (2)  That, for the purpose of determining any liability under the Securities
Act of 1933,  each such post-effective  amendment 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 remove from registration by  means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    (4) That, for purposes of determining any liability under the Securities Act
of 1933, each filing of the Registrant's annual report pursuant to Section 13(a)
or 15(d)  of  the  Securities Exchange  Act  of  1934 that  is  incorporated  by
reference in the registration statement shall be deemed to be a new registration
statement  relating to the securities offered  therein, and the offering of such
securities at that time  shall be deemed  to be the  initial bona fide  offering
thereof.

    Insofar  as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to  directors, officers and controlling persons of  the
Registrant  pursuant to the  foregoing provisions, or  otherwise, the Registrant
has been advised that in the  opinion of the Securities and Exchange  Commission
such  indemnification is against public  policy as expressed in  the Act and is,
therefore, unenforceable. In the event that a claim for indemnification  against
such  liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director,  officer or controlling person  of the Registrant in  the
successful  defense  of any  action,  suit or  proceeding)  is asserted  by such
director, officer or controlling person in connection with the securities  being
registered, the Registrant will, unless in the opinion of its counsel the matter
has  been settled  by controlling  precedent, submit  to a  court of appropriate
jurisdiction the question whether such  indemnification by it is against  public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Statement to  be  signed  on  its behalf  by  the  undersigned,  thereunto  duly

Plan. The Committee shall keep minutes  of its meetings. A quorum shall  consist
of  not fewer than two members  of the Committee and a  majority of a quorum may
authorize any  action. Any  decision  or determination  reduced to  writing  and
signed  by a majority of all  of the members of the  Committee shall be as fully
effective as if made by a majority vote  at a meeting duly called and held.  The
Committee  shall  consist of  at  least two  (2)  officers or  directors  of the
Company. No member of the Committee shall  be liable for any action, failure  to
act,  determination or  interpretation made in  good faith with  respect to this
Plan or any transaction hereunder, except for liability arising from his or  her
own  willful misfeasance, gross  negligence or reckless disregard  of his or her
duties. The Company hereby agrees to indemnify each member of the Committee  for
all  costs and  expenses and,  to the  extent permitted  by applicable  law, any
liability  incurred  in  connection  with  defending  against,  responding   to,
negotiating  for the settlement of or otherwise dealing with any claim, cause of
action or  dispute  of  any kind  arising  in  connection with  any  actions  in
administering  this  Plan  or in  authorizing  or denying  authorization  to any
transaction hereunder.
 
    3.2Subject to  the  express  terms  and conditions  set  forth  herein,  the
       Committee shall have the power from time to time to:
 
        (a)  determine those Eligible  Persons to whom  Options shall be granted
    under the Plan and the number of such Options to be granted and to prescribe
    the terms and conditions (which need not be identical) of each such  Option,
    including  the purchase price per Share subject to each Option, and make any
    amendment or modification to any Agreement consistent with the terms of  the
    Plan;
 
        (b) to construe and interpret the Plan and the Options granted hereunder
    and   to  establish,  amend  and  revoke   rules  and  regulations  for  the
    administration of the Plan,  including, but not  limited to, correcting  any
    defect  or supplying any  omission, or reconciling  any inconsistency in the
    Plan or in  any Agreement, in  the manner and  to the extent  it shall  deem
    necessary  or advisable so  that the Plan complies  with applicable law, and
    otherwise to make the Plan fully effective. All decisions and determinations
    by the Committee in the exercise of  this power shall be final, binding  and
    conclusive  upon the Company, its Subsidiaries, the Optionees, and all other
    persons having any interest therein;
 
                                       2
<PAGE>
        (c) to determine the duration and  purposes for leaves of absence  which
    may  be granted to an Optionee on an individual basis without constituting a
    termination of employment or service for purposes of the Plan;
 
        (d) to exercise  its discretion with  respect to the  powers and  rights
    granted to it as set forth in the Plan; and
 
        (e)  generally, to exercise such powers and  to perform such acts as are
    deemed necessary or advisable to promote  the best interests of the  Company
    with respect to the Plan.
 
    4.  STOCK SUBJECT TO THE PLAN.
 
    4.1The  maximum number  of Shares  that may be  made the  subject of Options
       granted under the Plan  is 100,000. Upon a  Change in Capitalization  the
maximum  number  of Shares  shall be  adjusted  in number  and kind  pursuant to
Section 7. The Company shall  reserve for the purposes of  the Plan, out of  its
authorized  but unissued Shares or out of Shares held in the Company's treasury,
or partly out  of each,  such number  of Shares as  shall be  determined by  the
Board.
 
    4.2Upon  the granting  of an  Option, the  number of  Shares available under
       Section 4.1 for the granting of  further Options shall be reduced by  the
number of Shares in respect of which the Option is granted or denominated.
 
    4.3Whenever  any outstanding Option or  portion thereof expires, is canceled
       or is otherwise terminated for  any reason without having been  exercised
in  respect of the entire Option, the  Shares allocable to the expired, canceled
or otherwise  terminated portion  of the  Option  may again  be the  subject  of
Options granted hereunder.
 
    5.  OPTION GRANTS FOR ELIGIBLE PERSONS.
 
    5.1   AUTHORITY OF  COMMITTEE.  Subject  to the provisions  of the Plan, the
Committee shall have full and final  authority to select those Eligible  Persons
who  will receive Options, the terms and  conditions of which shall be set forth
in an Agreement.
 
    5.2  PURCHASE PRICE.  The purchase price or the manner in which the purchase
price is to be determined  for Shares under each  Option shall be determined  by
the  Committee  and set  forth  in the  Agreement;  provided, however,  that the
purchase price per Share under each Option shall not be less than the par  value
of a Share on the date the Option is granted.
 
    5.3   MAXIMUM DURATION.  Options granted hereunder shall be for such term as
the Committee shall determine, provided that an Option shall not be  exercisable
after  the  expiration  of ten  (10)  years from  the  date it  is  granted. The
Committee may, subsequent to the granting of any Option, extend the term thereof
but in no event shall the term  as so extended exceed the maximum term  provided
for in the preceding sentence.
 
    5.4   VESTING.   Each Option  shall become exercisable  in such installments
(which need  not be  equal)  and at  such  times as  may  be designated  by  the
Committee  and  set  forth  in  the  Agreement.  To  the  extent  not exercised,
installments shall accumulate and  be exercisable, in whole  or in part, at  any
time after becoming exercisable, but not later than the date the Option expires.
The Committee may accelerate the exercisability of any Option or portion thereof
at any time.
 
    5.5   MODIFICATION.  No  modification of an Option  shall adversely alter or
impair any  rights  or  obligations  under the  Option  without  the  Optionee's
consent.
 
    5.6  NON-TRANSFERABILITY.  No Option granted hereunder shall be transferable
by  the Optionee  to whom  granted except  by will  or the  laws of  descent and
distribution, and  an  Option may  be  exercised  during the  lifetime  of  such
Optionee  only by the Optionee  or his or her  guardian or legal representative.
The terms  of  such Option  shall  be final,  binding  and conclusive  upon  the
beneficiaries, executors, administrators, heirs and successors of the Optionee.
 
                                       3
<PAGE>
    5.7   METHOD OF EXERCISE.  The exercise of an Option shall be made only by a
written notice delivered in person or by mail to the Secretary of the Company at
the Company's principal executive office, specifying the number of shares to  be
purchased  and accompanied by payment therefor  and otherwise in accordance with
the Agreement pursuant to which the  Option was granted. The purchase price  for
any Shares purchased pursuant to the exercise of an Option shall be paid in full
in  cash upon such exercise. Notwithstanding  the foregoing, the Committee shall
have discretion to determine at the time of grant of each Option or at any later
date (up  to and  including  the date  of exercise)  that  the form  of  payment
acceptable  in respect of the  exercise of such Option  may consist of either of
the following (or  any combination thereof):  (i) cash or  (ii) the transfer  of
Shares  to  the Company  upon such  terms  and conditions  as determined  by the
Committee. Any Shares  transferred to  the Company  as payment  of the  purchase
price  under an  Option shall be  valued at their  Fair Market Value  on the day
preceding the  date of  exercise of  such Option.  In addition,  Options may  be
exercised  through a registered broker-dealer pursuant to such cashless exercise
procedures (other than Share withholding) which  are, from time to time,  deemed
acceptable by the Committee. The Optionee shall deliver the Agreement evidencing
the  Option to the Secretary of the Company who shall endorse thereon a notation
of such exercise and return such Agreement to the Optionee. No fractional Shares
(or cash in lieu  thereof) shall be  issued upon exercise of  an Option and  the
number  of Shares that  may be purchased  upon exercise shall  be rounded to the
nearest number of whole Shares.
 
    5.8  RIGHTS OF OPTIONEES.  No Optionee shall be deemed for any purpose to be
the owner of any Shares  subject to any Option unless  and until (i) the  Option
shall  have been exercised pursuant to the terms thereof, (ii) the Company shall
have issued and delivered Shares to  the Optionee and (iii) the Optionee's  name
shall  have been entered as a stockholder of record on the books of the Company.
Thereupon, the Optionee shall  have full voting,  dividend, and other  ownership
rights  with respect to such Shares, subject to such terms and conditions as may
be set forth in the applicable Agreement.
 
    6.  EFFECT OF A TERMINATION OF SERVICE.
 
    The Agreement evidencing the grant of each Option shall set forth the  terms
and  conditions applicable to  such Option upon  a termination or  change in the
Optionee's status as an Eligible Person,  (including a termination or change  by
reason  of  the sale  of the  Company's interest  in any  Subsidiary, Affiliate,
Associate or Division), which shall be as the Committee may, in its  discretion,
determine at the time the Option is granted or thereafter.
 
    7.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.
 
    (a)  In  the  event  of  a Change  in  Capitalization,  the  Committee shall
conclusively determine the appropriate adjustments,  if any, to the (i)  maximum
number  and class of Shares  or other stock or  securities with respect to which
Options may be granted under the Plan,  and (ii) the number and class of  Shares
or  other stock or  securities which are subject  to outstanding Options granted
under the Plan and the purchase price therefor, if applicable.
 
    (b) If,  by reason  of a  Change  in Capitalization,  an Optionee  shall  be
entitled  to exercise  an Option  with respect  to new,  additional or different
shares of stock or  securities, such new, additional  or different shares  shall
thereupon  be subject  to all  of the  conditions, restrictions  and performance
criteria which were applicable to the Shares subject to the Option, as the  case
may be, prior to such Change in Capitalization.
 
    8.  EFFECT OF CERTAIN TRANSACTIONS.
 
    Except  as  otherwise provided  in an  Agreement,  in the  event of  (i) the
liquidation or dissolution of the Company  or (ii) a merger or consolidation  of
the  Company (a "Transaction"), the Plan  and the Options issued hereunder shall
continue in  effect  in accordance  with  their respective  terms,  except  that
following a Transaction each Optionee shall be entitled to receive in respect of
each Share subject to any outstanding Options, upon exercise of any Options, the
same   number  and  kind   of  stock,  securities,   cash,  property,  or  other
consideration  that  each  holder  of  a  Share  was  entitled  to  receive   in
 
                                       4
<PAGE>
the  Transaction  in respect  of a  Share; provided,  however, that  such stock,
securities, cash, property, or other  consideration shall remain subject to  all
of  the conditions, restrictions and  performance criteria which were applicable
to the Options prior to such Transaction.
 
    9.  TERMINATION AND AMENDMENT OF THE PLAN.
 
    The Plan shall terminate on the  day preceding the tenth anniversary of  the
date  of its adoption by the Board and  no Option may be granted thereafter. The
Board may sooner terminate the Plan and the Board may at any time and from  time
to  time amend,  modify or  suspend the  Plan; provided,  however, that  no such
amendment, modification,  suspension or  termination shall  impair or  adversely
alter any Options theretofore granted under the Plan, except with the consent of
the  Optionee, nor shall any  amendment, modification, suspension or termination
deprive any Optionee of any Shares which he or she may have acquired through  or
as a result of the Plan.
 
    10.  NON-EXCLUSIVITY OF THE PLAN.
 
    The  adoption of the Plan  by the Board shall  not be construed as amending,
modifying or  rescinding any  previously approved  incentive arrangement  or  as
creating any limitations on the power of the Board to adopt such other incentive
arrangements  as  it  may  deem desirable,  including,  without  limitation, the
granting of stock options otherwise than  under the Plan, and such  arrangements
may be either applicable generally or only in specific cases.
 
    11.  LIMITATION OF LIABILITY.
 
    As  illustrative of  the limitations  of liability  of the  Company, but not
intended to be exhaustive thereof, nothing in the Plan shall be construed to:
 
        (i) give any person any right to be granted an Option other than at  the
    sole discretion of the Committee;
 
        (ii) give any person any rights whatsoever with respect to Shares except
    as specifically provided in the Plan;
 
       (iii)  limit  in  any way  the  right  of the  Company  to  terminate the
    employment of any person at any time; or
 
       (iv) be evidence of any agreement or understanding, expressed or implied,
    that  the  Company  will  employ  any  person  at  any  particular  rate  of
    compensation or for any particular period of time.
 
    12.  REGULATIONS AND OTHER APPROVALS; GOVERNING LAW.
 
    12.1
       Except  as to  matters of federal  law, this  Plan and the  rights of all
       persons  claiming  hereunder  shall   be  construed  and  determined   in
accordance  with the  laws of  the State  of Delaware  without giving  effect to
conflicts of laws principles thereof.
 
    12.2
       The obligation of the Company to  sell or deliver Shares with respect  to
       Options  granted under the Plan shall  be subject to all applicable laws,
rules and regulations,  including all  applicable federal  and state  securities
laws, and the obtaining of all such approvals by governmental agencies as may be
deemed necessary or appropriate by the Committee.
 
    12.3
       The  Board may make  such changes as  may be necessary  or appropriate to
       comply with the rules and regulations of any government authority.
 
    12.4
       Each Option  is subject  to the  requirement  that, if  at any  time  the
       Committee  determines, in its discretion,  that the listing, registration
or qualification of  Shares issuable  pursuant to the  Plan is  required by  any
securities  exchange  or under  any  state or  federal  law, or  the  consent or
approval of any  governmental regulatory  body is  necessary or  desirable as  a
condition  of, or in connection with, the grant  of an Option or the issuance of
Shares, no Options shall be granted or  payment made or Shares issued, in  whole
or in part, unless listing, registration, qualification, consent or approval has
been effected or obtained free of any conditions as acceptable to the Committee.
 
                                       5
<PAGE>
    12.5
       Notwithstanding  anything contained in  the Plan or  any Agreement to the
       contrary, in the event that  the disposition of Shares acquired  pursuant
to  the Plan is not  covered by a then  current registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), and is not  otherwise
exempt  from such registration, such Shares shall be restricted against transfer
to the extent required by the Securities  Act and Rule 144 or other  regulations
thereunder.  The Committee may require  any individual receiving Shares pursuant
to an Option granted under the Plan, as a condition precedent to receipt of such
Shares, to  represent and  warrant to  the Company  in writing  that the  Shares
acquired  by such  individual are  acquired without  a view  to any distribution
thereof and will not be sold or transferred other than pursuant to an  effective
registration thereof under said Act or pursuant to an exemption applicable under
the  Securities Act  or the  rules and  regulations promulgated  thereunder. The
certificates evidencing any  of such  Shares shall be  appropriately amended  to
reflect their status as restricted securities as aforesaid.
 
    13.  MISCELLANEOUS.
 
    13.1   MULTIPLE AGREEMENTS.  The terms  of each Option may differ from other
Options granted under  the Plan at  the same time,  or at some  other time.  The
Committee  may also grant more than one Option to a given Eligible Person during
the term of the Plan, either in addition to, or in substitution for, one or more
Options previously granted to that Eligible Person.
 
    13.2  WITHHOLDING OF  TAXES.  (a)  At such times  as an Optionee  recognizes
taxable  income in connection  with the receipt  of Shares or  cash hereunder (a
"Taxable Event"), the Optionee shall pay to  the Company an amount equal to  the
federal,  state and local income  taxes and other amounts  as may be required by
law to be  withheld by the  Company in  connection with the  Taxable Event  (the
"Withholding  Taxes") prior  to the  issuance, or  release from  escrow, of such
Shares or the payment of such cash.  The Company shall have the right to  deduct
from any payment of cash to an Optionee an amount equal to the Withholding Taxes
in  satisfaction of the obligation to  pay Withholding Taxes. In satisfaction of
the obligation to pay Withholding Taxes to the Company, the Optionee may make  a
written  election (the "Tax Election"), which may be accepted or rejected in the
discretion of  the Committee  to have  withheld  a portion  of the  Shares  then
issuable  to  him or  her having  an aggregate  Fair Market  Value equal  to the
Withholding Taxes.
 
    13.3  EFFECTIVE DATE.  The effective date of the Plan shall be as determined
by the Board.

solicit or divert the business of any persons or entities who are or were 
vendors, joint venturers, contractors, clients, customers, consultants, 
agents or representatives of EastWest or Purchaser during the one (1) year 
period prior to the Closing Date or with whom EastWest or Purchaser has 
discussed the possibility of becoming a vendor, joint venturer, contractor, 
client, customer, consultant, agent or representative (unless 

                                       14

<PAGE>
such person or entity shall have previously advised EastWest or Purchaser in 
writing that it has no interest in continuing such discussions) or plans to 
engage in such discussions, to his or her knowledge, or otherwise interfere 
with or attempt to interfere with the relationship between EastWest or 
Purchaser and any such person or entity, for a period of five (5) consecutive 
years from the date hereof anywhere EastWest or Purchaser currently conducts, 
or, to his or her knowledge, plans to conduct its business; provided, 
however, that the running of such time period shall be tolled during any 
period of time during which he or she violates this paragraph;
 
    (ii) He or she will not use or disclose to anyone except authorized
personnel of EastWest or Purchaser, whether or not for his or her benefit or
otherwise, any confidential matters concerning EastWest or its business or
Purchaser or its business, including, without limitation, secrets, lists of
vendors, joint venturers, contractors, clients, customers, consultants, agents,
representatives or employees, mailing lists, details of contracts, pricing
policies, operational methods, marketing plans or strategies, product
development and techniques or plans, research and development programs and
plans, business acquisition plans, recruitment plans, designs and design
projects and any other research or business information concerning EastWest or
Purchaser which EastWest or Purchaser currently deems to be confidential;
 
    (iii) He or she will not, directly or indirectly, solicit, encourage to
leave, or hire any officer of EastWest or Purchaser or any person who at the
time of such solicitation or hire has an employment agreement with EastWest or
Purchaser or is involved in sales, marketing or planning activities on behalf of
EastWest or Purchaser (a "Key Person") or who had been a Key Person within the
previous twelve (12) months.
 
    (b) He or she acknowledges that the foregoing restrictions have been 
negotiated with the advice of counsel, are reasonable in light of the 
previous and existing business relationships between EastWest and Purchaser 
and the acquisition of the Shares, including a substantial acquisition of 
goodwill, by the Purchaser, and agrees that in the event of any breach 
thereof the harm to Purchaser will be irreparable and without adequate remedy 
at law, and therefore that injunctive relief with respect thereto will be 
appropriate, and that Purchaser shall have no obligation to pay any amounts 
which may still be owing to him or her under this Agreement or any note 
executed in connection therewith.
 
    (c) If any court determines that any of the provisions of this Section 4.2,
or any part thereof, is invalid 

                                       15

<PAGE>
or unenforceable, the remainder of this Section 4.2 shall not be affected and 
shall be given full effect, without regard to the invalid portions;
 
    (d) If any court determines that any of the provisions of this Section 4.2,
or any part thereof, is unenforceable because of the scope of any of the
covenants contained therein, then the parties agree that such provision shall be
deemed reduced so that the covenants impose the maximum restraints permissible
under applicable law and, in its reduced form, such provision shall than be
enforceable and shall be enforced.
 
    4.3  GUARANTY.  Purchaser shall guaranty payment by EastWest to Sellers of
the base compensation amounts set forth in Section 3(a) of the Employment and
Non-Competition Agreements between EastWest and each of the Sellers.

                                       18

<PAGE> 
    7.3  SURVIVAL.  The respective representations and warranties made by the 
parties in this Agreement or in any certificate or other document delivered 
pursuant hereto or in connection herewith shall survive the Closing Date for 
a period of five (5) years, but thereafter shall expire unless a claim with 
respect thereto shall have been made in writing against the indemnifying 
party pursuant to Section 7.4 hereof; provided, that the foregoing limitation 
shall not apply to representations and warranties under Sections 2.1, 2.4, 
2.5, 2.7, 2.16, 2.18 and 2.23, which shall survive without limitation 
hereunder.
 
    7.4  NOTICE OF CLAIM.  In the event that any party hereto asserts a claim
for indemnification hereunder, such party seeking indemnification (the
"Indemnified Party") shall give written notice to the other party or parties
(the "Indemnifying Party") specifying the facts constituting the basis for such
claim and the amount, if known, of the claim asserted. The failure of the
Indemnifying Party, within a period of ninety (90) days after the giving of such
notice by the Indemnified Party, to give written notice to the Indemnified Party
of the intention to contest such claim shall be deemed an agreement that the
claim is a valid claim and at such time as it is known, the amount thereof shall
be paid promptly by the Indemnifying Party.
 
    7.5  RIGHT TO CONTEST CLAIMS OF THIRD PARTIES.  If an Indemnified Party
asserts a claim for indemnification hereunder because of a claim made by any
claimant not a party to this Agreement, the Indemnified Party shall give the
other party or parties reasonably prompt notice thereof, but in no event more
than ten (10) business days after said assertion is actually known to the
Indemnified Party; provided, however, that the right of an Indemnified Party to
be indemnified hereunder in respect of claims made by a third party shall not be
adversely affected by a failure to give such notice unless, and then only to the
extent that, an Indemnifying Party is materially prejudiced thereby. The
Indemnifying Party shall have the right, upon written notice to the Indemnified
Party, and using counsel reasonably satisfactory to the Indemnified Party, to
investigate, secure, contest or settle the claim alleged by such third party
(hereinafter called a "Third-Party Claim"), provided that the Indemnified Party
may participate voluntarily, at its own expense, in any such Third-Party Claim
through representatives and counsel of its own choice, and, provided further,
that the Indemnifying Party unconditionally acknowledges to the Indemnified
Party in writing his or its obligation to indemnify the Indemnified Party with
respect to all elements of such Third-Party Claim, and posts a bond in an
appropriate amount and that any action by the Indemnifying Party relating to the
Third-Party Claim shall be without prejudice to the Indemnified Party. The
Indemnified Party shall not settle or compromise any 

                                       19

<PAGE>
Third-Party Claim for which it is entitled to indemnification hereunder 
without the prior written consent of the Indemnifying Party (which shall not 
be unreasonably withheld) unless suit shall have been instituted against it 
and the Indemnifying Party shall not have taken control of the defense of 
such Third-Party Claim after notification thereof as provided in this Section 
7.5.
 
    Except as provided otherwise in the immediately preceding sentence, the
Indemnifying Party shall bear all costs of such Third-Party Claim and shall
indemnify and hold the Indemnified Party harmless against and from all costs,
fees and expenses of such Third-Party Claim. Unless and until the Indemnifying
Party elects to defend the Third-Party Claim, the Indemnified Party shall have
the full right, at its option, to do so and to look to the Indemnifying Party
under the provisions of this Purchase Agreement for the amount of the costs, if
any, of defending the Contest. The failure of the Indemnifying Party to respond
in writing to the aforesaid notice of the Indemnified Party with respect to such
Third-Party Claim within twenty (20) days after receipt thereof shall be deemed
an election not to defend the same. If the Indemnifying Party does not assume
the defense of any such Third-Party Claim, including any litigation resulting
therefrom, (a) the Indemnified Party may defend against such claim or
litigation, in such manner as it may deem appropriate, including, but not
limited to, settling such claim or litigation, after giving notice of the same
to the Indemnifying Party, on such terms as the Indemnified Party may deem
appropriate, and (b) the Indemnifying Party shall be entitled to participate in
(but not to control) the defense of such action, with its own counsel at its own
expense. If the Indemnifying Party thereafter seeks to question the manner in
which the Indemnified Party defended such Third-Party Claim or the amount or
nature of any such settlement, the Indemnifying Party shall have the burden to
prove by a preponderance of the evidence that the Indemnified Party did not
defend or settle such Third-Party Claim in a reasonably prudent manner.
 
    The parties hereto shall make mutually available to each other all relevant
information in their possession relating to any such Third-Party Claim and shall
cooperate in the defense thereof.

    7.6  ARBITRATION.
 
    (a) Resolution of any and all disputes between the parties to this Agreement
(each a "Party" and together the "Parties") arising from or in connection with
this Agreement whether based on contract, tort, common law, equity, statute,
regulation, order or otherwise ("Disputes"), shall be exclusively governed by
and settled in accordance with the provisions of this Section 7.6; provided,
that the foregoing shall not preclude equitable or other judicial relief to
enforce the provisions of this Section 7.6 or Section 4.2 or to preserve the
status quo pending resolution of Disputes hereunder.
 
    (b) The Parties hereby agree to submit to arbitration all Disputes, which
arbitration shall be final and binding upon the Parties, their successors and
assigns.
 
    (c) Either Party may initiate such arbitration by delivery of a demand
therefor (the "Arbitration Demand") to the other Party.
 
    (d) The arbitration shall be conducted in Alexandria, Virginia, by a sole
arbitrator selected by agreement of the Parties not later than 10 days after
delivery of the Arbitration Demand or, failing such agreement, appointed
pursuant to the Commercial Arbitration Rules of the American Arbitration
Association, as amended from time to time (the "AAA Rules"). If an arbitrator
becomes unable to serve, his successor(s) shall be similarly selected or
appointed.
 
    (e) The arbitration shall be conducted pursuant to the Federal Arbitration
Act and the Virginia Uniform Arbitration Act and such procedures as the Parties
may agree or, in the absence of or failing such agreement, pursuant to the AAA
Rules. Notwithstanding the foregoing, (i) each Party shall have the right to
audit the books and records of the other Party that are reasonably related to
the Dispute; (ii) each Party shall provide to the other, reasonably in advance
of any hearing, copies of all documents which a Party intends to present in such
hearing; (iii) all hearings shall be conducted on an expedited schedule; and
(iv) all proceedings shall be confidential, except that either Party may at its
expense make a stenographic record thereof.
 
    (f) The arbitrator shall complete all hearings not later than 90 days after
his selection or appointment, and shall make a final award not later than 30
days thereafter. The arbitrator shall apportion all costs and expenses of the
arbitration, including the arbitrator's fees and expenses and fees and expenses
of experts ("Arbitration Costs") between the 

                                       21

<PAGE>
prevailing and non-prevailing Party as the arbitrator shall deem fair and 
reasonable. In circumstances where a Dispute has been asserted or defended 
against on grounds that the arbitrator deems manifestly unreasonable, the 
arbitrator may assess all Arbitration Costs against the non-prevailing Party 
and may include in the award the prevailing Party's attorney's fees and 
expenses in connection with any and all proceedings under this Section 7.6.

THIS WARRANT IS NON-TRANSFERABLE. NEITHER THIS WARRANT NOR THE SHARES 
ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED UNDER THE 
SECURITIES ACT OF 1933 OR UNDER ANY APPLICABLE STATE SECURITIES LAW, AND THIS 
WARRANT AND SUCH SHARES MAY NOT BE SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED

                                       OF
                           PHP HEALTHCARE CORPORATION
 
    PHP Healthcare Corporation, a Delaware corporation (the "Company"),
certifies that, in accordance with a certain Stock Purchase Agreement of even
date herewith among the Company, David E. Berman (the "Registered Owner") and
Mary Ellen Michael-Fleming (David E. Berman and Mary Ellen Michael-Fleming
referred to collectively herein as the "Sellers"), the Registered Owner has been
granted on the date hereof (the "Grant Date") the right, subject to the terms of
this Warrant, to purchase from the Company a total of Twenty Two Thousand Five
Hundred (22,500) fully paid and nonassessable shares of its common stock, $.01
par value per share (the "Shares"), subject to adjustment as provided herein.

    This Warrant shall entitle the Registered Owner to purchase, in whole at any

Shares and Purchase Price in respect of which the Warrant is being exercised 
and shall be signed by the person or persons exercising the Warrant on behalf 
of the Registered Owner. Such person or persons shall deliver this Warrant to

take appropriate action to effect the transfer to the Registered Owner of the 
number of Shares as to which such exercise was effective.

    5. TERMINATION.

    5.1 This Warrant and all rights of the registered owner under this 
Warrant shall terminate (i) upon the expiration of the Exercise Term, to the 
extent not previously exercised; and (ii) if the employment of the Registered 
Owner by EastWest Research Corporation ("EastWest") under the Employment and 
Non-Competition Agreement of even date herewith between EastWest and the 
Registered Owner (or any amendment thereto) (the "Employment Agreement") is 
terminated pursuant to Section 4(a), (b), (c) or (d) thereof or the 
Registered Owner terminates the Employment Agreement prior to the expiration 
of its term.

    5.2 This Warrant and all rights of the Registered Owner under this 
Warrant shall terminate one (1) year after the Employment Agreement is

    6. DILUTION.

    6.1 If the Company shall (i) pay a dividend on its common stock in shares 
of its common stock, (ii) subdivide its outstanding common stock, or (iii) 
combine its outstanding common stock into a smaller number of shares, then 
the Purchase Price of any Shares not yet purchased hereunder shall be 
proportionately decreased in the case of such payment or subdivision, or 
increased in the case of such combination; and upon such adjustment of the 
Purchase Price, the Registered Owner shall thereafter be entitled to 
purchase, at the new purchase price, the number of shares, calculated to the 
nearest full share, obtained by multiplying the number of shares of common 
stock issuable upon exercise of this Warrant immediately prior to such 
adjustment by the Purchase Price in effect immediately prior to such 
adjustment and dividing the product so obtained by the new purchase price.

    6.2 Whenever any adjustment is required in the number of shares of common 
stock for which this Warrant is exercisable, the Company shall (i) file with 
its stock record books a statement describing in reasonable detail the 
adjustment and the calculation used in determining that adjustment and (ii) 
deliver a copy of that statement to the Registered Owner.

Registered Owner any right to continued employment by EastWest or to interfere
in any way with the right of EastWest to 

                                       3

terminate the Registered Owner's employment under the Employment Agreement at 
any time.
 
    8. TRANSFER RESTRICTIONS.
 
    This Warrant is binding upon and is solely for the benefit of the parties
hereto. It shall not be transferable other than by will or the laws of descent
and distribution and is binding upon the Registered Owner's executors, heirs and
administrators. Neither this Warrant nor the shares issuable upon exercise of
this Warrant have been registered under the Securities Act of 1933 or under any
applicable state securities law, and this Warrant and such shares may not be
sold, transferred, pledged, hypothecated or otherwise disposed of in whole or in
part in the absence of an effective registration statement under that Act and
applicable state securities law or an exemption from such registration.
 
    9. REGISTRATION RIGHTS.

    9.1 In the event the Company files a registration statement under the 
Securities Act of 1933 (the "Act") which relates to a public offering of its 
securities (except in connection with an offering to employees) and which 
offering is of a type and registered pursuant to a form of registration 
statement that permits registration of the Shares, the Company agrees, upon 
the written request of the Sellers, to have such registration statement and 
the prospectus included therein include and relate to, and meet the 
requirements of the Act with respect to, the public offering of the Shares 
owned by the Sellers (the "Included Shares") so as to permit the public sale 
thereof in compliance with the Act.

    9.2 The Company shall give written notice to the Sellers of its intention 
to file a registration statement under the Act relating to a public offering 
of the aforesaid securities at least thirty (30) days prior to the filing of 
such registration statement. The Sellers shall deliver their written request 
to include their Shares within fifteen (15) days thereafter. Neither the 
delivery of such notice by the Company nor of such request by the Sellers 
shall in any way obligate the Company to file such registration statement and 
notwithstanding the filing of such registration statement the Company may, at 
any time prior to the effective date thereof, determine to withdraw such 
registration statement without liability to the Sellers.

    9.3 The Company shall supply to the Sellers two (2) executed copies of 
each registration statement and that reasonable number of copies of the 
preliminary, final and other prospectus in conformity with requirements of 
the Act and the 

                                       4

<PAGE>
Rules and Regulations promulgated thereunder and such other documents as the 
Sellers shall reasonably request.

    9.4 The Company shall cooperate in taking such action as may be necessary 
to register or qualify the Included Shares under such other securities acts 
or blue sky laws of such jurisdictions as the Sellers shall reasonably 
request and to do any and all other acts and things which may be necessary or 
advisable to enable the Sellers to consummate such proposed sale or other 
disposition of the Included Shares in any such jurisdiction; provided that in 
no event shall the Company be obligated, in connection therewith, to qualify 
to do business or to file a general consent to service of process in any 
jurisdiction where it shall not then be qualified.

    9.5 The Company shall keep effective for a period of not less than ninety 
(90) days after the initial effectiveness thereof all such registrations 
under the Act and cooperate in taking such action as may be necessary to keep 
effective such other registrations and qualifications, and do any and all 
other acts and things for such period--not to exceed six (6) months--as may 
be necessary to permit the public sale or other disposition of the Included 
Shares.

    9.6 The Company shall pay the registration and filing fees, underwriting 
commissions, transfer taxes, and underwriter's expense allowance attributable 
to the Included Shares and the reasonable fees and expenses of the Sellers' 
counsel.

    9.7 In no event shall the Company be required to include Shares owned by 
the Sellers in a registration statement pursuant to the requirements of this 
Section 9 more than once. Such inclusion shall be conditioned upon a timely 
receipt by the Company in writing of information as to the terms of such 
public offering furnished by or on behalf of the Sellers, and such other 
information as the Company may reasonably require from the Sellers, or any 
underwriter for them, for inclusion in such registration statement.
 
    10. AMENDMENT.
 
    This Warrant may be amended or terminated, and any terms or condition hereof
may be waived, only by a written instrument executed on behalf of each party
hereto.
 
    11. NOTICE.
 
    All notices, requests, claims, demands and other communications hereunder
shall be in writing and shall be deemed to have been duly given when delivered
