               $69,000,000 PRINCIPAL AMOUNT OF 6 1/2% CONVERTIBLE
                        SUBORDINATED DEBENTURES DUE 2002
                   (Interest payable June 15 and December 15)
 
                        3,499,937 SHARES OF COMMON STOCK
                               ------------------
 
    This Prospectus relates  to (i)  $69,000,000 aggregate  principal amount  of
6  1/2% Convertible Subordinated  Debentures due 2002  (the "Debentures") of PHP
Healthcare Corporation, a  Delaware corporation ("PHP"  or the "Company"),  (ii)
2,532,110  shares of  the Common  Stock, par value  $.01 per  share (the "Common
Stock"), of the  Company which  are initially  issuable upon  conversion of  the
Debentures  plus such additional indeterminate number  of shares of Common Stock
as may  become  issuable  upon conversion  of  the  Debentures as  a  result  of
adjustments  to the  conversion price  (the "Conversion  Shares"), and  (iii) an
additional 967,827 shares of  Common Stock (including  shares issuable upon  the
exercise   of  options  or  the   conversion  of  convertible  securities)  (the
"Additional Shares").  The  Conversion  Shares and  the  Additional  Shares  are
collectively  referred to herein as the "Shares." The Debentures, the Conversion
Shares and the  Additional Shares  that are being  registered hereby  are to  be
offered  for the account of the holders thereof (the "Selling Securityholders").
The Debentures were  acquired from  the Company by  Smith Barney  Inc. and  Dean
Witter  Reynolds Inc. (the "Initial Purchasers")  in December 1995 in connection
with a  private offering  (the "Debenture  Offering"). See  "Description of  the
Debentures."  The Additional Shares  were acquired from  the Company by Shamrock
Investments, Charles P. Reilly, Michael E. Gallagher, Jonathan J. Spees and John
P. Cole in September  1994 in connection  with the issuance  of Common Stock  to
Shamrock  Investments and the merger of J.P. Cole & Associates, Inc. and Paragon
Ambulatory Surgery, Inc. into the Company.
 
   
    The Debentures are convertible into Common Stock of the Company at any  time
after the 60th day following the date of original issuance of the Debentures and
at  or before  maturity, unless  previously redeemed,  at a  conversion price of
$27.25 per share, subject  to adjustment in certain  events. On March 15,  1996,
the closing price of the Common Stock on the New York Stock Exchange was $26 1/4
per share. The Common Stock is traded under the symbol PPH.
    
 
    The  Debentures  do  not provide  for  a  sinking fund.  The  Debentures are
redeemable at the option of the Company, in whole or in part, at the  redemption
prices set forth in this Prospectus, together with accrued interest, except that
no  redemption may be made  prior to December 17,  1998. Upon a Repurchase Event
(as defined herein),  each holder  of Debentures shall  have the  right, at  the
holder's  option, to require the Company  to repurchase such holder's Debentures
at a purchase price equal to 100% of the principal amount thereof, plus  accrued
interest. See "Description of Debentures -- Certain Rights to Require Repurchase
of Debentures."
 
    The Debentures are unsecured obligations of the Company and are subordinated
to all present and future Senior Indebtedness (as defined herein) of the Company
and  will be  effectively subordinated  to all  indebtedness and  liabilities of
subsidiaries of the Company. The Indenture  does not restrict the incurrence  of
any  other indebtedness or  liabilities by the Company  or its subsidiaries. See
"Description of Debentures -- Subordination."
 
    The Debentures have been  designated for trading  in the Private  Offerings,
Resales  and  Trading  through  Automated  Linkages  ("PORTAL")  Market.  For  a
description of certain income tax consequences to holders of the Debentures, see
"Certain United States Federal Income Tax Consequences." The Initial  Purchasers
have  advised the Company that  they intend to make  a market in the Debentures.
The Initial Purchasers, however, are not obligated to do so and any such  market
making may be discontinued at any time without notice, in the sole discretion of
the  Initial  Purchasers. No  assurance can  be  given that  any market  for the
Debentures will develop or be maintained.
 
    The Debentures  and the  Conversion Shares  are being  registered to  permit
public  secondary trading of the Debentures and, upon conversion, the underlying
Common Stock, by the holders  thereof from time to time  after the date of  this
Prospectus.  The Company  has agreed, among  other things, to  bear all expenses
(other than  underwriting  discounts,  selling  commissions  and  fees  and  the
expenses  of counsel and other advisors to  the holders of the Debentures or the
underlying Common Stock)  in connection with  the registration and  sale of  the
Debentures  and  the underlying  Common Stock  covered  by this  Prospectus. The
holders of the Additional Shares have agreed to pay their own expenses and bear,
on a pro rata basis, all incremental registration expenses that result from  the
inclusion  of the Additional Shares in  the Registration Statement of which this
Prospectus is a part.
 
    The Company will  not receive  any of  the proceeds  from the  sales of  the
Debentures  or the Shares by the Selling Securityholders. The Debentures and the
Shares may be offered in negotiated transactions or otherwise, at market  prices
prevailing  at the time of sale or at negotiated prices. In addition, the Shares
may be offered from time to time through ordinary brokerage transactions on  the
New York Stock Exchange. See "Plan of Distribution." The Selling Securityholders
may  be deemed to be "Underwriters" as defined in the Securities Act of 1933, as
amended (the "Securities Act").  If any broker-dealers are  used by the  Selling
Securityholders,  any commissions paid to  broker-dealers and, if broker-dealers
purchase any Debentures or  Shares as principals, any  profits received by  such
broker-dealers  on the resale  of the Debentures  or Shares may  be deemed to be
underwriting discounts or commissions under the Securities Act. In addition, any
profits realized by the Selling Securityholders may be deemed to be underwriting
commissions.

                                  THE COMPANY
 
   
    PHP  Healthcare Corporation ("PHP"  or the "Company")  designs, develops and
operates patient-oriented Integrated Systems of  Care ("ISOCs") which serve  the
needs  of  managed  care  organizations,  self-insured  employers,  health  care
providers and provider  systems, and government  agencies. The Company  develops
and operates each integrated system by: (i) developing and maintaining a network
of  physicians, hospitals, and other providers; (ii) organizing and managing the
individual and group  practices of  physicians who participate  in the  network;
(iii)  operating information systems  to coordinate and  integrate the services,
measure outcomes, and provide financial results of the system; and (iv) entering
into contracts  with various  third  party payors,  such as  health  maintenance
organizations  ("HMOs"), insurers, or employee health benefit plans on behalf of
the network. The  Company manages  ISOCs for its  clients, owns  a Medicaid  HMO
primarily serving the District of Columbia, and manages inpatient and outpatient
health care services under government contracts.
    
 
    PHP was organized as a Delaware corporation in January 1986 and succeeded to
the business of a predecessor corporation by merger in March 1986. The Company's
corporate  headquarters  is  located  at  11440  Commerce  Park  Drive,  Reston,
Virginia, 22091, and  its telephone number  at that address  is (703)  758-3600.
Unless  the context otherwise  requires, all references  herein to the "Company"
include PHP and its subsidiaries.

                                  RISK FACTORS
 
    In addition to the other information contained in this Prospectus and in the
documents incorporated  herein  by  reference,  prospective  purchasers  of  the
Debentures  and the Shares should carefully consider the factors set forth below
before purchasing the Debentures or the Shares.
 
RECENT ENTRY INTO COMMERCIAL MANAGED HEALTH CARE MARKET
 
    Until fiscal 1994, PHP operated almost  exclusively as a provider of  health
care  services to federal, state and  local government agencies. During the past
two fiscal years,  however, the  Company has invested  significant resources  in
developing  its ISOC  product for the  commercial managed health  care market in
order to refocus its  business from that  of a government  contractor to a  full
service  managed  care company.  There can  be no  assurance that  the Company's
strategy will continue to  be successful or that  modifications to its  strategy
will not be required.
 
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. Although  the Company  was
profitable  for the  fiscal year ended  April 30,  1995 and for  the nine months
ended January 31,  1996, there  can be  no assurance  that it  will continue  to
operate  profitably, or have earnings or cash flow sufficient to comply with the
financial covenants  to which  it is  subject  or to  cover its  fixed  charges,
including  those attributable to the Debentures.  As a consequence of the losses
reported in fiscal  1993 and  1994, 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
the  effect of  blocking payments  on the Debentures  and could  have a material
adverse effect on  the Company's  business, financial condition  and results  of
operations.
    
 
DEPENDENCE ON CERTAIN CONTRACTS
 
   
    For the year ended April 30, 1995, and for the nine months ended January 31,
1996,  39% and 38%, 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
(concerning the Company's  Medicaid HMO in  the District of  Columbia) and  with
Medigroup,  Inc., a wholly owned subsidiary of Blue Cross and Blue Shield of New
Jersey, Inc. ("BCBSNJ") (concerning the development and management of ten  ISOCs
in  New Jersey), and accounted  for 22% and 17%,  respectively, of the Company's
revenues in fiscal 1995.  For the nine months  ended January 31, 1996,  revenues
derived  from  these  contracts represented  29%  and 9%,  respectively,  of the
Company's revenue. The loss of either  of these contracts would have a  material
adverse  effect on  the Company's business,  financial condition  and results of
operations.
    
 
    The agreement  with  BCBSNJ  provides  BCBSNJ the  right  to  terminate  the
agreement  upon 90 days notice  without cause upon the  payment of a termination
fee  to  the  Company.  The   agreement  also  contains  provisions   permitting
termination by BCBSNJ for cause in the event of a material breach by PHP or upon
the  occurrence of certain other circumstances, including PHP's failure to cause
all ten centers to be fully operational by March 31, 1995. Although nine of  the
ten  centers were fully operational by March  31, 1995, one center was not fully
operational until September  1995. The  Company believes,  for various  reasons,
that  BCBSNJ may  not validly  terminate the  agreement based  upon the  date of
completion of the tenth center. The parties have also discussed the  possibility
of  renegotiating the  agreement or otherwise  altering their  relationship on a
mutually agreeable  basis,  although no  specific  proposal is  presently  under
consideration.  There can be no assurance that BCBSNJ will not seek to terminate
the agreement based upon the  date of completion of the  tenth center or on  any
other  basis  or  that, if  BCBSNJ  does seek  to  do  so, the  Company  will be
successful in preventing such a termination.

    The Company's accounts receivable as of January 31, 1996 include amounts due
from the District of Columbia Department of Human Services and the United States
Department of Health  and Human  Services as  follows: approximately  $8,000,000
related  to  the  cost  settlement  for  the  three-year  contract  period ended
September 30, 1994, and approximately $4,800,000 related to the cost  settlement
for  the one-year  contract period ended  September 30, 1995.  These amounts are
subject to audit and the audits are expected to be completed during the  current
fiscal  year.  In addition,  at January  31, 1996,  as a  result of  the current
federal budget and the District  of Columbia's fiscal difficulties, the  Company
has  past due amounts from the District of Columbia and the Department of Health
and Human Services of approximately $4.5 million due January 1, 1996, which  was
received  February 26, 1996, and an additional $4.5 million due February 1, 1996
and $4.5 million  due March 1,  1996 currently outstanding.  The Company  cannot
predict  when or whether these amounts will  be paid. The failure of the Company
to collect these 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 "shared risk"
contracts, are arrangements between the Company and a 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 shared-risk 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 system  of care.  The  Company competes  for exclusive  primary  care
physician  affiliations  with a  variety of  systems including  group practices,
individual practice  associations  ("IPAs"),  health  maintenance  organizations
("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 ISOCs effectively.
 
LIMITATIONS ON REIMBURSEMENT
 
   
    A  major  portion of  the Company's  revenues are  derived from  third party
payors, such as governmental programs, private insurance plans and managed  care
organizations.  In particular, for  the year ended  April 30, 1995  and the nine
months ended January 31, 1996, approximately  22% and 29%, 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
    
 
                                       5
<PAGE>
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.
 
    The  U.S. Congress has passed a  fiscal year 1996 budget reconciliation bill
that provides for  reductions in the  rate of spending  increases over the  next
seven  years  of approximately  $270 billion  in the  Medicare program  and $165
billion in the  Medicaid program.  The bill  provides for,  among other  things,
converting  the  federal share  of the  Medicaid  program to  a block  grant and
gradually reducing the overall  growth of the  federal share from  approximately
ten  percent annually  to approximately  four percent  by fiscal  year 2000. The
annual increase in the federal share would  vary from state to state based on  a
variety  of factors. Although the initial  reconciliation bill was vetoed by the
President, no assurance can be given that reductions in the rate of increase  in
spending  for these programs,  if ultimately signed  into law, would  not have a
material adverse effect on the Company's operations. Any loss of revenue  caused
by  trends in  the health  care industry  toward cost  containment and oversight
could have a material adverse effect on the Company's business.
 
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)  account  for  approximately  50%  of  the  Company's  revenues. 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. 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.
 
                                       6
<PAGE>
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.
 
HEALTH CARE REGULATION
 
    The health care industry is subject to extensive federal regulation relating
to licensure, conduct of operations and prices for services.
 
    The laws  of  many  states  prohibit physicians  from  splitting  fees  with
non-physicians  and  prohibit non-physician  entities from  practicing medicine.
These laws vary from state to state,  have been subject to limited judicial  and
regulatory  interpretation, and  are enforced  by the  courts and  by regulatory
authorities with broad discretion. Although  the Company seeks to structure  its
operations  so as to comply with these laws,  there can be no assurance that the
Company's present or future  operations will not  be successfully challenged  as
violating, or determined to have violated, such laws, or that the enforceability
of  the provisions of agreements governing  such operations will not be limited.
Any such result could have a material adverse effect on the Company.
 
    The laws in  most states  also regulate the  business of  insurance and  the
operation  of HMOs. Many states also regulate the establishment and operation of
networks of health care providers. Although  the Company seeks to structure  its
operations  so as  to comply  with these  laws in  the states  in which  it does
business, there can  be no  assurance that future  interpretations of  insurance
laws  and health care network laws by the regulatory authorities in these states
or in the states into which the Company may expand will not require licensure or
a restructuring  of some  or  all of  the  Company's operations.  The  Company's
Medicaid  HMO is not presently subject to licensure requirements in the District
of Columbia.  However, legislation  has been  proposed which  would require  the
licensure  of  HMOs in  the  District of  Columbia  and subject  the  Company to
additional regulatory requirements. The  Company is unable  to predict what  HMO
legislation  or  regulation,  if  any,  will  be  adopted  in  the  District  of
 
                                       7
<PAGE>
Columbia and what effect, if any,  such legislation or regulation would have  on
the Company's business. No assurance can be given that future HMO legislation or
regulation  in  the District  of Columbia  or in  other states  will not  have a
material adverse  effect  on  the Company's  business,  financial  condition  or
results of operation.
 
    Anti-fraud  and abuse amendments  codified under the  Social Security Act of
1935,  as  amended  (the  "Social  Security  Act"),  prohibit  certain  business
practices  and relationships  that may affect  the provision and  cost of health
care services  reimbursable  under the  Medicare  and Medicaid  programs.  These
amendments   include  anti-kickback  provisions  prohibiting  the  solicitation,
payment, receipt or  offering of  any direct  or indirect  remuneration for  the
referral  of Medicare or Medicaid  patients or for the  ordering or providing of
Medicare or  Medicaid  covered  services,  items  or  equipment.  Sanctions  for
violating  the  anti-kickback provisions  include  criminal penalties  and civil
sanctions, including fines and possible exclusion from the Medicare and Medicaid
programs. In addition, Section 1877 of the Social Security Act (the "Stark law")
restricts physician referrals  to certain providers,  including hospitals,  with
which  they have a  financial arrangement. Sanctions for  violation of the Stark
law include civil money penalties and  exclusion from the Medicare and  Medicaid
programs.  The Stark law and the anti-kickback provisions of the Social Security
Act are broadly worded and often  vague, and the future interpretation of  these
provisions  and  their  applicability  to  the  Company's  operations  cannot be
predicted with certainty.  Although the  Company seeks to  arrange its  business
relationships  so as to comply  with these laws, there  can be no assurance that
the Company's present or future operations will not be accused of violating,  or
be  determined to have violated,  such provisions. Any such  result could have a
material adverse effect on the Company.
 
HEALTH CARE REFORM
 
    In recent years,  an increasing  number of legislative  proposals have  been
introduced  in Congress and  in some state legislatures  that would effect major
changes in the health care system, either nationally or at the state level.  The
Company  is unable to predict what health  care reform legislation, if any, will
be adopted and what effect, if any,  such legislation may have on the  Company's
business.  No assurance can be given  that future health care reform legislation
will not have  a material adverse  effect on the  Company's business,  financial
condition or results of operations.
 
    Provisions  in the fiscal year 1996  reconciliation bill passed by Congress,
if  signed  into  law,  would   eliminate  the  federally  mandated   individual
entitlement  to Medicaid benefits  and give the states  wide latitude in setting
eligibility standards and benefit levels. In addition, the bill would reduce for
a number of  states the level  of state  spending necessary to  qualify for  the
maximum  federal matching. Such changes, if adopted, could result in a reduction
in the number of individuals participating in the Medicaid program. No assurance
can be given that such changes would  not have a material adverse effect on  the
Company's business.
 
SUBSTANTIAL INDEBTEDNESS
 
   
    The  Company's indebtedness is substantial  in relation to its stockholders'
equity. At January 31, 1996, the Company's total long-term debt, net of  current
portion, accounted for 71% of its total capitalization.
    
 
SUBORDINATION OF DEBENTURES
 
   
    The Debentures are subordinate in right of payment to all current and future
Senior  Indebtedness of  the Company.  Senior Indebtedness  includes all secured
indebtedness of  the  Company (other  than  claims  of trade  creditors  of  the
Company),  whether existing  on or  created or  incurred after  the date  of the
issuance of the Debentures, that is not  made subordinate to or pari passu  with
the Debentures by the instrument creating the indebtedness. At January 31, 1996,
the aggregate amount of Senior Indebtedness outstanding and the aggregate amount
of  indebtedness and  other liabilities of  the Company and  its subsidiaries to
which the  Debentures  are  effectively  subordinated  was  approximately  $14.2
million.  The Indenture  does not limit  the amount  of additional indebtedness,
including Senior Indebtedness, which  the Company can  create, incur, assume  or
guarantee. By reason of such
    
 
                                       8
<PAGE>
subordination  of the  Debentures, in the  event of  the insolvency, bankruptcy,
liquidation, reorganization, dissolution or  winding up of  the business of  the
Company  or upon a default in payment with respect to any Senior Indebtedness of
the Company or an event of  default with respect to such indebtedness  resulting
in  the acceleration thereof, the assets of the Company will be available to pay
the amounts due  on the  Debentures only after  all Senior  Indebtedness of  the
Company  has  been paid  in full.  In  addition, holders  of the  Debentures are
effectively  subordinated  to   the  claims  of   creditors  of  the   Company's
subsidiaries.   In  the  event  of   the  insolvency,  bankruptcy,  liquidation,
reorganization, dissolution or winding up of  the business of any subsidiary  of
the  Company, creditors of such  subsidiary generally will have  the right to be
paid in full before any  distribution is made to the  Company or the holders  of
the Debentures.
 
LIMITATIONS ON REPURCHASE OF DEBENTURES UPON A REPURCHASE EVENT
 
    In the event of a Repurchase Event, which includes a Change in Control and a
Termination  of Trading (each as defined  herein) each holder of Debentures will
have the right, at the holder's option, to require the Company to repurchase all
or a portion of such  holder's Debentures at a purchase  price equal to 100%  of
the  principal amount thereof plus accrued  interest to the repurchase date. The
Company's ability to repurchase  the Debentures upon a  Repurchase Event may  be
limited  by the terms of the Company's Senior Indebtedness and the subordination
provisions of the Indenture. Further, the  ability of the Company to  repurchase
Debentures  upon a  Repurchase Event  will be  dependent on  the availability of
sufficient funds and  compliance with applicable  securities laws.  Accordingly,
there  can  be no  assurance that  the Company  will be  able to  repurchase the
Debentures upon a Repurchase  Event. The term "Repurchase  Event" is limited  to
certain  specified  transactions and  may not  include  other events  that might
adversely affect the financial condition of the Company or result in a downgrade
of the  credit rating  of the  Debentures, nor  would the  requirement that  the
Company  offer to repurchase the Debentures  upon a Repurchase Event necessarily
afford holders of the Debentures protection  in the event of a highly  leveraged
transaction,   reorganization,  merger  or  similar  transaction  involving  the
Company. See "Description of Debentures."
 
ABSENCE OF PUBLIC MARKET
 
    There is no existing market for the Debentures and there can be no assurance
as to the  liquidity of any  markets that  may develop for  the Debentures,  the
ability of the holders to sell their Debentures or the price at which holders of
the  Debentures may be able  to sell their Debentures.  Future trading prices of
the Debentures  will depend  on  many factors,  including, among  other  things,
prevailing  interest rates,  the Company's operating  results, the  price of the
Common Stock and the market for similar securities. The Initial Purchasers  have
informed  the Company that the Initial Purchasers intend to make a market in the
Debentures; however, the Initial Purchasers are  not obligated to do so and  any
such  market making activity may be terminated at any time without notice to the
holders of the Debentures. See  "Description of the Debentures --  Registrations
Rights;  Liquidated Damages."  The Debentures  are eligible  for trading  in the
PORTAL Market; however, the Company does not intend to apply for listing of  the
Debentures on any securities exchange.
 
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 (collectively,  the  "Voting Group")  currently  hold an  aggregate  of
approximately 25% of the outstanding Common Stock
 
                                       9
<PAGE>
(excluding  shares issuable  upon the exercise  of options or  the conversion of
convertible securities) and have  entered into a  voting agreement (the  "Voting
Agreement")  under  which  they  have  agreed  to  act  together  under  certain
circumstances. Assuming full conversion of the Debentures, the Voting Group will
hold approximately 21%  of the  outstanding Common Stock.  The Voting  Agreement
currently  provides that  it will  terminate on October  7, 1996.  If the Voting
Group acts together, they may exercise a controlling influence over the  outcome
of  matters submitted to the Company's  stockholders for approval. Moreover, the
Voting Group 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."
 
                                USE OF PROCEEDS
 
    The  Company will  not receive  any of  the proceeds  from the  sales of the
Debentures  or  the  Shares  by   the  Selling  Securityholders.  See   "Selling
Securityholders" for a list of those persons and entities receiving the proceeds
from the sales of the Debentures or the Shares.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
    The  Company's ratio of  earnings to fixed  charges for each  of the periods
indicated is as follows:

</TABLE>
    
 
    The ratio of earnings to fixed charges is computed by dividing fixed charges
into earnings from continuing operations before income taxes, minority  interest
and  extraordinary items plus  fixed charges. Fixed  charges consist of interest
expense, amortization of financing costs and the estimated interest component of
rent expense.

                           DESCRIPTION OF DEBENTURES
 
    The Debentures were issued under an indenture dated as of December 15,  1995
(the "Indenture"), between the Company and IBJ Schroder Bank & Trust Company, as
trustee  (the "Trustee"). The  following summaries of  certain provisions of the
Indenture do not purport to be complete and are subject to, and are qualified in
their entirety  by  reference  to,  all of  the  provisions  of  the  Indenture,
including  the definition therein of certain terms. Wherever particular sections
or defined terms  of the  Indenture are referred  to, such  sections or  defined
terms  are  incorporated  herein  by  reference.  Copies  of  the  Indenture are
available from  the Company  upon request  at  the address  provided on  page  3
herein.
 
GENERAL
 
    The  Debentures are  unsecured obligations  of the  Company, are  limited to
$69,000,000 in  aggregate principal  amount (including  the Initial  Purchasers'
over-allotment  option) and  mature on  December 15,  2002. The  Debentures bear
interest at the rate per annum shown on the front cover of this Prospectus  from
the  date of original issuance  of Debentures pursuant to  the Indenture or from
the most  recent  Interest Payment  Date  to which  interest  has been  paid  or
provided  for, payable semi-annually  on June 15  and December 15  of each year,
commencing June 15,  1996, to the  Person in  whose name the  Debenture (or  any
predecessor  Debenture) is registered at the  close of business on the preceding
June 1 or December  1, as the case  may be. Interest on  the Debentures will  be
paid on the basis of a 360-day year of twelve 30-day months.
 
    Principal  of, premium, if  any, and interest on,  the Debentures is payable
(i) in respect  of Debentures  held of record  by the  Depository Trust  Company
("DTC")  or its nominee in same day funds  on or prior to the payment dates with
respect to such  amounts and (ii)  in respect  of Debentures held  of record  by
holders other than DTC or its nominee, at the office of the Trustee in New York,
New  York,  and the  Debentures  may be  surrendered  for transfer,  exchange or
conversion at the office of the Trustee in New York, New York. In addition, with
respect to Debentures held of record by  holders other than DTC or its  nominee,
payment  of interest may be made, at the  option of the Company, by check mailed
to the address of the persons entitled thereto as it appears in the register for
the Debentures on the Regular Record Date for such interest.
 
    The Debentures are issued  only in registered form,  without coupons and  in
denominations of $1,000 or any integral multiple thereof. No service charge will
be  made for  any transfer or  exchange of  the Debentures, but  the Company may
require payment  of a  sum sufficient  to cover  any tax  or other  governmental
charge  and any other expenses (including the  fees and expenses of the Trustee)
payable in  connection therewith.  The Company  is not  required (i)  to  issue,
register the transfer of or exchange any Debentures during a period beginning at
the  opening of business  15 days before the  day of the mailing  of a notice of
redemption and ending at the  close of business on the  day of such mailing,  or
(ii)  to  register  the  transfer  of or  exchange  any  Debenture  selected for
redemption in whole  or in  part, except  the unredeemed  portion of  Debentures
being redeemed in part.
 
    All  moneys paid by the  Company to the Trustee or  any Paying Agent for the
payment of principal of and premium  and interest on any Debenture which  remain
unclaimed for two years after such principal, premium or interest become due and
payable  may be repaid to the Company.  Thereafter, the Holder of such Debenture
may, as an  unsecured general  creditor, look only  to the  Company for  payment
thereof.
 
    The  Indenture does not contain any provisions that would provide protection
to Holders of  the Debentures against  a sudden and  dramatic decline in  credit
quality  of the Company resulting from any takeover, recapitalization or similar
restructuring, except  as  described  below under  "Certain  Rights  to  Require
Repurchase of Debentures."
 
CONVERSION RIGHTS
 
    The  Debentures are convertible into Common Stock at any time after the 60th
day following  the date  of original  issuance of  the Debentures  and prior  to
redemption or final maturity, initially at the
 
                                       11
<PAGE>
conversion price of $27.25 per share. The right to convert Debentures which have
been called for redemption will terminate at the close of business on the second
business day preceding the Redemption Date. See "Optional Redemption" below.
 
    The  conversion price is subject to adjustment upon the occurrence of any of
the following events:  (i) the subdivision,  combination or reclassification  of
outstanding  shares of Common Stock; (ii) the  payment in shares of Common Stock
of a dividend  or distribution on  any class  of capital stock  of the  Company;
(iii)  the  issuance  of rights  or  warrants  to all  holders  of  Common Stock
entitling them to acquire shares of Common Stock at a price per share less  than
the  Current Market Price; (iv)  the distribution to holders  of Common Stock of
shares of capital stock other than Common Stock, evidences of indebtedness, cash
or assets (including securities, but  excluding dividends or distributions  paid
exclusively  in cash and dividends,  distributions, rights and warrants referred
to above); (v) a distribution consisting exclusively of cash (excluding any cash
distributions referred to in (iv)  above) to all holders  of Common Stock in  an
aggregate amount that, together with (A) all other cash distributions (excluding
any  cash distributions  referred to  in (iv) above)  made within  the 12 months
preceding such distribution and (B) any cash and the fair market value of  other
consideration  payable  in respect  of  any tender  offer  by the  Company  or a
subsidiary of the Company for the Common Stock consummated within the 12  months
preceding  such  distribution,  exceeds  12.5 percent  of  the  Company's market
capitalization (being the product of the  Current Market Price times the  number
of  shares of Common Stock  then outstanding) on the  date fixed for determining
the stockholders entitled to such distribution;  and (vi) the consummation of  a
tender offer made by the Company or any subsidiary of the Company for the Common
Stock which involves an aggregate consideration that, together with (X) any cash
and other consideration payable in respect of any tender offer by the Company or
a  subsidiary of  the Company  for the  Common Stock  consummated within  the 12
months preceding the  consummation of such  tender offer and  (Y) the  aggregate
amount  of all cash distributions (excluding  any cash distributions referred to
in (iv) above) to all holders of the Common Stock within the 12 months preceding
the consummation of  such tender offer,  exceeds 12.5 percent  of the  Company's
market  capitalization  at the  date of  consummation of  such tender  offer. No
adjustment of the conversion price will be required to be made until  cumulative
adjustments  amount to  at least  one percent of  the conversion  price, as last
adjusted. Any adjustment that  would otherwise be required  to be made shall  be
carried forward and taken into account in any subsequent adjustment.
 
    In  addition to the foregoing adjustments,  the Company will be permitted to
reduce the conversion price as  it considers to be  advisable in order that  any
event  treated for federal income  tax purposes as a  dividend of stock or stock
rights will not be taxable to the holders of the Common Stock or, if that is not
possible, to diminish  any income taxes  that are otherwise  payable because  of
such  event. In the case of any consolidation  or merger of the Company with any
other corporation (other  than one  in which  no change  is made  in the  Common
Stock), or any sale or transfer of all or substantially all of the assets of the
Company,  the  Holder  of  any Debenture  then  outstanding  will,  with certain
exceptions, have the right  thereafter to convert such  Debenture only into  the
kind  and amount  of securities,  cash and  other property  receivable upon such
consolidation, merger, sale or transfer by a  holder of the number of shares  of
Common  Stock into  which such Debenture  might have  been converted immediately
prior to such consolidation, merger, sale  or transfer; and adjustments will  be
provided  for  events  subsequent  thereto  that  are  as  nearly  equivalent as
practical to the conversion price adjustments described above.
 
    Fractional shares of Common Stock will  not be issued upon conversion,  but,
in  lieu thereof,  the Company will  pay a  cash adjustment based  upon the then
Closing Price  at  the close  of  business on  the  day of  conversion.  If  any
Debentures  are surrendered for  conversion during the period  from the close of
business on any Regular  Record Date through and  including the next  succeeding
Interest  Payment Date (except any such  Debentures called for redemption), such
Debentures when surrendered  for conversion  must be accompanied  by payment  in
next  day funds of an amount equal  to the interest thereon which the registered
Holder on  such  Regular  Date  is  to  receive.  Except  as  described  in  the
 
                                       12
<PAGE>
preceding  sentence, no  interest will  be payable  by the  Company on converted
Debentures with respect to any Interest  Payment Date subsequent to the date  of
conversion.  No other payment or  adjustment for interest or  dividends is to be
made upon conversion.
 
    The Indenture  provides that,  in the  event of  the occurrence  of  certain
events affecting the rights (the "Rights") distributed pursuant to the Company's
Rights  Agreement, dated as of April 10, 1992, with Riggs National Bank, NA (the
"Rights Agreement"), appropriate  adjustments to  the conversion  price will  be
made. In lieu of any such adjustment, the Company may amend the Rights Agreement
to  provide  that upon  conversion  of the  Debentures  the holder  thereof will
receive, in addition  to the  Common Stock  issuable upon  such conversion,  the
Rights  which attached to such shares of  Common Stock or would have attached to
such shares  if  the Rights  had  not become  separated  from the  Common  Stock
pursuant to the provisions of the Rights Agreement.
 
SUBORDINATION
 
    The  payment of the  principal of and  premium, if any,  and interest on the
Debentures are, to the extent set forth in the Indenture, subordinated in  right
of  payment to the prior payment in full of all Senior Indebtedness. If there is
a  payment  or  distribution  of  assets  to  creditors  upon  any  liquidation,
dissolution,   winding  up,  reorganization,  assignment   for  the  benefit  of
creditors, marshalling  of  assets  or any  bankruptcy,  insolvency  or  similar
proceedings  of  the Company,  the holders  of all  Senior Indebtedness  will be
entitled to receive payment in full of all amounts due or to become due  thereon
or  provision for such payment  in money or money's  worth before the Holders of
the Debentures  will  be entitled  to  receive any  payment  in respect  of  the
principal  of or premium, if any, or interest on the Debentures. In the event of
the acceleration of the  Maturity of the Debentures,  the holders of all  Senior
Indebtedness  will first be entitled  to receive payment in  full in cash of all
amounts due thereon  or provision  for such payment  in money  or money's  worth
before the Holders of the Debentures will be entitled to receive any payment for
the  principal of or premium, if any, or interest on the Debentures. No payments
on account of principal of or premium, if any, or interest on the Debentures  or
on account of the purchase or acquisition of Debentures may be made if there has
occurred  and is  continuing a  default in  any payment  with respect  to Senior
Indebtedness, any acceleration of the maturity of any Senior Indebtedness of  if
any judicial proceeding is pending with respect to any such default.
 
    Senior  Indebtedness  is  defined  in  the  Indenture  as  (a)  all  secured
indebtedness of the Company  for money borrowed, excluding  the claims of  trade
creditors  of the Company, whether  outstanding on the date  of execution of the
Indenture or  thereafter created,  incurred or  assumed, except  any such  other
indebtedness  that by the terms  of the instrument or  instruments by which such
indebtedness was created or incurred expressly provides that it (i) is junior in
right of payment to the Debentures or (ii) ranks PARI PASSU in right of  payment
with   the   Debentures,   and  (b)   any   amendments,   renewals,  extensions,
modifications, refinancings and  refundings of  any of the  foregoing. The  term
"indebtedness  for  money borrowed"  when used  with respect  to the  Company is
defined to mean  (i) any  obligation of, or  any obligation  guaranteed by,  the
Company  for the repayment of borrowed money (including without limitation fees,
penalties and other obligations in respect thereof), whether or not evidenced by
bonds, debentures, notes or other written instruments, (ii) any deferred payment
obligation of, or any such obligation guaranteed by, the Company for the payment
of the purchase  price of  property or  assets evidenced  by a  note or  similar
instrument,  and (iii) any obligation of,  or any such obligation guaranteed by,
the Company for the payment of rent  or other amounts under a lease of  property
or  assets which obligation is required to  be classified and accounted for as a
capitalized lease on the balance sheet  of the Company under generally  accepted
accounting principles.
 
    The  Debentures are obligations exclusively of the Company. A portion of the
operations of the  Company are currently  conducted through subsidiaries,  which
are  separate and distinct legal entities  and have no obligation, contingent or
otherwise, to pay  any amounts due  pursuant to  the Debentures or  to make  any
funds  available therefor,  whether by  dividends, loans  or other  payments. In
addition,
 
                                       13
<PAGE>
the payment of dividends and certain loans  and advances to the Company by  such
subsidiaries  may be subject  to certain statutory  or contractual restrictions,
are contingent upon the earnings of such subsidiaries and are subject to various
business considerations.
 
    The Debentures are  effectively subordinated to  all indebtedness and  other
liabilities  and commitments (including trade payables and lease obligations) of
the Company's subsidiaries. Any  right of the Company  to receive assets of  any
such  subsidiary upon the  liquidation or reorganization  of any such subsidiary
(and the consequent  right of the  Holders of the  Debentures to participate  in
those   assets)  will  be  effectively  subordinated   to  the  claims  of  that
subsidiary's creditors,  except  to  the  extent  that  the  Company  is  itself
recognized  as a creditor  of such subsidiary,  in which case  the claims of the
Company would still  be subordinate to  any security interest  in the assets  of
such  subsidiary and any indebtedness of such  subsidiary senior to that held by
the Company.
 
   
    The  Indenture  does  not  limit  or  prohibit  the  incurrence  of   Senior
Indebtedness.  At January 31, 1996, the  aggregate amount of Senior Indebtedness
outstanding and the aggregate  amount of indebtedness  and other liabilities  of
the  Company  and  its  subsidiaries to  which  the  Debentures  are effectively
subordinated was approximately $14.2 million. The Company also expects to  incur
Senior Indebtedness from time to time in the future.
    
 
OPTIONAL REDEMPTION
 
    The  Debentures are  redeemable, at the  Company's option, in  whole or from
time to time in part, at any time  on or after December 17, 1998, upon not  less
than  15 nor more than 60 days' notice mailed to each Holder of Debentures to be
redeemed at its address appearing in the Security Register and prior to Maturity
at the following Redemption  Prices (expressed as  percentages of the  principal
amount)  plus accrued interest to  the Redemption Date (subject  to the right of
Holders of record on the relevant Regular Record Date to receive interest due on
an Interest Payment Date that is on or prior to the Redemption Date).
 
    If redeemed during the  12-month period beginning December  15, in the  year
indicated (December 17, in the case of 1998), the redemption price shall be:

    No sinking fund is provided for the Debentures.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
    The  Company will  not consolidate  with or merge  into any  other Person or
convey, transfer or lease its properties and assets substantially as an entirety
to any  Person, or  permit any  Person to  consolidate with  or merge  into  the
Company or convey, transfer or lease its properties substantially as an entirety
to   the  Company,  unless  (a)  if   applicable,  the  Person  formed  by  such
consolidation or into which the Company  is merged or the Person or  corporation
which  acquires the  properties and  assets of  the Company  substantially as an
entirety is a corporation, partnership  or trust organized and validly  existing
under  the laws  of the United  States or any  state thereof or  the District of
Columbia and expressly assumes payment of the principal of and premium, if  any,
and interest on the Debentures and performance and observance of each obligation
of  the Company under the Indenture,  (b) after consummating such consolidation,
merger, transfer or  lease, no Default  or Event  of Default will  occur and  be
continuing,  (c) such  consolidation, merger  or acquisition  does not adversely
affect the validity or enforceability of the Debentures and (d) the Company  has
delivered  to the  Trustee an Officer's  Certificate and an  Opinion of Counsel,
each stating  that such  consolidation, merger,  conveyance, transfer  or  lease
complies with the provisions of the Indenture.
 
                                       14
<PAGE>
CERTAIN RIGHTS TO REQUIRE REPURCHASE OF DEBENTURES
 
    In  the event of any Repurchase Event (as defined below) occurring after the
date of issuance of the Debentures and  on or prior to Maturity, each Holder  of
Debentures  will have the right, at the  Holder's option, to require the Company
to repurchase  all or  any part  of the  Holder's Debentures  on the  date  (the
"Repurchase  Date") that is 30  days after the date  the Company gives notice of
the Repurchase Event  as described  below at  a price  (the "Repurchase  Price")
equal  to 100% of the principal amount thereof, together with accrued and unpaid
interest to the Repurchase Date. On or prior to the Repurchase Date, the Company
shall deposit with the Trustee or a  Paying Agent an amount of money  sufficient
to  pay the  Repurchase Price of  the Debentures which  are to be  repaid on the
Repurchase Date.
 
    Failure by the Company  to provide timely notice  of a Repurchase Event,  as
provided  for below,  or to  repurchase the  Debentures when  required under the
preceding paragraph  will result  in an  Event of  Default under  the  Indenture
whether  or not such repurchase is  permitted by the subordination provisions of
the Indenture.
 
    On or before the 15th  day after the occurrence  of a Repurchase Event,  the
Company  is  obligated to  mail to  all Holders  of Debentures  a notice  of the
occurrence of such Repurchase Event, the Repurchase Date, the date by which  the
repurchase  right must be exercised, the Repurchase Price for Debentures and the
procedures which the Holder must follow to exercise this right. To exercise  the
repurchase right, the Holder of a Debenture must deliver, on or before the close
of  business on the  Repurchase Date, irrevocable written  notice to the Company
(or an agent designated by the Company  for such purpose) and to the Trustee  of
the  Holder's exercise of such right,  together with the certificates evidencing
the Debentures with respect to which the right is being exercised, duly endorsed
for transfer.
 
    A "Repurchase Event" shall have occurred upon the occurrence of a Change  in
Control (as defined below) or a Termination of Trading (as defined below).
 
    A  "Change in Control" shall occur when: (i) all or substantially all of the
Company's assets are  sold as  an entirety  to any  person or  related group  of
persons;  (ii) there  shall be  consummated any  consolidation or  merger of the
Company (A) in which the Company is not the continuing or surviving  corporation
(other  than a  consolidation or  merger with a  wholly owned  subsidiary of the
Company in which all shares of Common Stock outstanding immediately prior to the
effectiveness thereof are changed into or exchanged for the same  consideration)
or  (B)  pursuant  to which  the  Common  Stock would  be  converted  into cash,
securities or other property, in each case, other than a consolidation or merger
of the Company in which the holders of the Common Stock immediately prior to the
consolidation or merger have, directly or indirectly, at least a majority of the
total voting power of all classes of capital stock entitled to vote generally in
the election of directors of the continuing or surviving corporation immediately
after such consolidation or merger in substantially the same proportion as their
ownership of Common Stock immediately before such transaction; (iii) any person,
or any persons acting together which would constitute a "group" for purposes  of
Section  13(d) of the Exchange Act,  together with any affiliates thereof, shall
beneficially own (as defined in Rule 13d-3 under the Exchange Act) at least  50%
of  the  total voting  power  of all  classes of  capital  stock of  the Company
entitled to vote generally in the election of directors of the Company; (iv)  at
any  time  during  any  consecutive  two-year  period,  individuals  who  at the
beginning of  such period  constituted the  Board of  Directors of  the  Company
(together  with any new directors  whose election by such  Board of Directors or
whose nomination for election by the stockholders of the Company was approved by
a vote of 662 3% of the directors then still in office who were either directors
at the beginning of such period or whose election or nomination for election was
previously so approved)  cease for any  reason to constitute  a majority of  the
Board  of  Directors  of the  Company  then in  office;  or (v)  the  Company is
liquidated or dissolved or adopts a plan of liquidation or dissolution.
 
                                       15
<PAGE>
    A "Termination of Trading" shall occur if the Common Stock (or other  common
stock  into which  the Debentures  are then  convertible) is  neither listed for
trading on a U.S.  national securities exchange nor  approved for trading on  an
established automated over-the-counter trading market in the United States.
 
    The right to require the Company to repurchase Debentures as a result of the
occurrence  of a Repurchase Event could create  an event of default under Senior
Indebtedness of the Company, as a result of which any repurchase could, absent a
waiver, be  blocked  by the  subordination  provisions of  the  Debentures.  See
"Subordination."  Failure  by  the  Company to  repurchase  the  Debentures when
required will  result in  an Event  of Default  with respect  to the  Debentures
whether or not such repurchase is permitted by the subordination provisions. The
Company's ability to pay cash to the Holders of Debentures upon a repurchase may
be  limited by  certain financial  covenants contained  in the  Company's Senior
Indebtedness.
 
    In the event a Repurchase Event occurs and the Holders exercise their rights
to require the Company to repurchase  Debentures, the Company intends to  comply
with applicable tender offer rules under the Exchange Act, including Rules 13e-4
and 14e-1, as then in effect, with respect to any such purchase.
 
    The  foregoing  provisions  would  not  necessarily  afford  Holders  of the
Debentures protection in  the event  of highly leveraged  or other  transactions
involving  the  Company  that may  adversely  affect Holders.  In  addition, the
foregoing provisions may discourage open market purchases of the Common Stock or
a non-negotiated tender or exchange offer  for such stock and, accordingly,  may
limit  a stockholder's ability to realize a premium over the market price of the
Common Stock in connection with any such transaction.
 
EVENTS OF DEFAULT
 
    The following are Events of Default under the Indenture with respect to  the
Debentures:  (a) default in  the payment of  principal of or  any premium on any
Debenture when due  (even if  such payment  is prohibited  by the  subordination
provisions  of the Indenture); (b) default in the payment of any interest on any
Debenture when due, which default continues for 30 days (even if such payment is
prohibited by the  subordination provisions  of the Indenture);  (c) failure  to
provide  timely notice of a  Repurchase Event as required  by the Indenture; (d)
default in the payment of  the Repurchase Price in  respect of any Debenture  on
the  Repurchase  Date  therefor  (even  if such  payment  is  prohibited  by the
subordination provisions of the  Indenture); (e) default  in the performance  of
any  other covenant of the Company in  the Indenture continued for 60 days after
written notice by the Trustee or Holders of at least 25% in aggregate  principal
amount  of the Outstanding Debentures as  provided in the Indenture; (f) default
under any bond,  debenture, note  or other  evidence of  indebtedness for  money
borrowed  by the Company or any subsidiary of the Company or under any mortgage,
indenture or instrument under which there may be issued or by which there may be
secured or evidenced any indebtedness for  money borrowed by the Company or  any
subsidiary  of  the  Company,  whether such  indebtedness  now  exists  or shall
hereafter be  created, which  default  shall constitute  a  failure to  pay  the
principal of indebtedness in excess of $5,000,000 when due and payable after the
expiration  of any  applicable grace period  with respect thereto  or shall have
resulted in indebtedness in excess of $5,000,000 becoming or being declared  due
and  payable prior to the  date on which it would  otherwise have become due and
payable, without such indebtedness having been discharged, or such  acceleration
having  been rescinded or annulled, within a period of 30 days after there shall
have been given to the Company by the Trustee or to the Company and the  Trustee
by  the Holders of at least 25% in aggregate principal amount of the Outstanding
Debentures a written notice specifying such default and requiring the Company to
cause such  indebtedness to  be  discharged or  cause  such acceleration  to  be
rescinded  or  annulled; and  (g) certain  events  in bankruptcy,  insolvency or
reorganization of the Company or any subsidiary of the Company.
 
    If an Event of  Default with respect  to the Debentures  shall occur and  be
continuing,  the  Trustee or  the  Holders of  not  less than  25%  in aggregate
principal amount of the Outstanding Debentures may
 
                                       16
<PAGE>
declare the principal of and premium, if  any, on all such Debentures to be  due
and  payable immediately, but if the Company cures all Events of Default (except
the nonpayment of interest on, premium, if any, and principal of any Notes)  and
certain  other conditions  are met,  such declaration  may be  canceled and past
defaults may be  waived by  the Holders  of a  majority in  principal amount  of
Outstanding  Debentures. If an  Event of Default  shall occur as  a result of an
event of  bankruptcy,  insolvency  or  reorganization  of  the  Company  or  any
subsidiary  of the  Company, the  aggregate principal  amount of  the Debentures
shall automatically become due and payable.  The Company is required to  furnish
to  the Trustee  annually a statement  as to  the performance by  the Company of
certain of its obligations  under the Indenture  and as to  any default in  such
performance.  The Indenture provides that the Trustee may withhold notice to the
Holders of the Debentures  of any continuing default  (except in the payment  of
the  principal of  or premium,  if any,  or interest  on any  Debentures) if the
Trustee considers it in the interest of Holders of the Debentures to do so.
 
MODIFICATION, AMENDMENTS AND WAIVERS
 
    Modifications and amendments of the Indenture may be made by the Company and
the Trustee without the consent of the Holders to: (a) cause the Indenture to be
qualified under the Trust Indenture Act; (b) evidence the succession of  another
Person  to the Company and the assumption by any such successor of the covenants
of the Company herein  and in the  Debentures; (c) add to  the covenants of  the
Company  for the benefit  of the Holders  or an additional  Event of Default, or
surrender any  right  or  power  conferred upon  the  Company;  (d)  secure  the
Debentures;  (e) make provision with respect to the conversion rights of Holders
in the event of a consolidation, merger or sale of assets involving the Company,
as required by  the Indenture; (f)  evidence and provide  for the acceptance  of
appointment  by a successor Trustee with respect  to the Debentures; or (g) cure
any ambiguity, correct  or supplement any  provision which may  be defective  or
inconsistent with any other provision, or make any other provisions with respect
to  matters  or  questions  arising  under  the  Indenture  which  shall  not be
inconsistent with the provisions  of the Indenture,  PROVIDED, HOWEVER, that  no
such  modification or amendment may adversely affect the interest of the Holders
in any material respect.
 
    Modifications and amendments of the Indenture may be made by the Company and
the Trustee with the consent of the Holders of a majority in aggregate principal
amount  of  the  Outstanding  Debentures;   PROVIDED,  HOWEVER,  that  no   such
modification  or  amendment  may, without  the  consent  of the  Holder  of each
Outstanding Debenture, (a) change  the Stated Maturity of  the principal of,  or
any  installment of interest on, such Debenture, (b) reduce the principal amount
of, or premium, if any, or interest on, such Debenture, (c) adversely affect the
right to convert such  Debenture or modify the  subordination provisions in  the
Indenture  in a manner adverse to the  Holders, (d) change the place or currency
of payment of principal of, or premium, if any, or interest on, such  Debenture,
(e)  adversely affect the right to require the Company to repurchase Debentures,
(f) impair the right to institute suit  for the enforcement of any such  payment
on  or with respect to such Debenture, or (g) reduce the percentage in principal
amount of Outstanding Debentures, the consent  of whose Holders is required  for
modification  or amendment  of the  Indenture or  for waiver  of compliance with
certain provisions of the Indenture or for waiver of certain defaults.
 
    The Holders of a majority in  aggregate principal amount of the  Outstanding
Debentures  may, on behalf of all Holders of Debentures, waive compliance by the
Company with certain restrictive provisions of  the Indenture. The Holders of  a
majority  in aggregate  principal amount of  the Outstanding  Debentures may, on
behalf of all Holders of Debentures, waive any past default under the  Indenture
with respect to the Debentures, except a default in the payment of principal of,
or  premium, if any,  or interest or in  respect of a  provision which under the
Indenture cannot be modified  or amended without consent  of the Holder of  each
Outstanding Debenture.
 
SATISFACTION AND DISCHARGE
 
    The  Company  may  discharge  its  obligations  under  the  Indenture  while
Debentures remain Outstanding if (a) all Outstanding Debentures will become  due
and payable at their scheduled
 
                                       17
<PAGE>
maturity  within one  year or (b)  all Outstanding Debentures  are scheduled for
redemption within one year,  and in either case  the Company has deposited  with
the Trustee an amount sufficient to pay and discharge all Outstanding Debentures
on the date of their scheduled maturity or the scheduled date of redemption.
 
DELIVERY AND FORM OF DEBENTURES
 
    The  Debentures were sold to Qualified  Institutional Buyers (each, a "QIB")
in reliance on Rule 144A under  the Securities Act and were initially  deposited
with,  or on behalf of,  The Depository Trust Company  ("DTC") and registered in
the name of Cede & Co., as DTC's nominee, in the form of a global Debenture (the
"Rule 144A Global Debenture"). Interests in the Rule 144A Global Debenture  will
be  shown  in, and  transfers  thereof will  be  effected only  through, records
maintained by DTC and its participants ("participants"). Only QIBs may elect  to
hold   Debentures   through  the   Depository.   Debentures  purchased   by  (i)
institutional accredited investors that  are not QIBs  and (ii) persons  outside
the  United States in  offshore transactions pursuant to  Regulation S under the
Securities Act ("Regulation S Purchasers") are represented by Debentures  issued
in  definitive registered form without  coupons (the "Certificated Debentures").
Only Debentures held by Qualified Institutional Buyers may be represented by the
Rule 144A Global Debenture. The Rule  144A Global Debenture will be (i)  reduced
in  principal amount to reflect the  subsequent transfer by owners of beneficial
interest in  the Rule  144A Global  Debenture  to a  Regulation S  Purchaser  or
another  person who is not a Qualified  Institutional Buyer or (ii) increased in
principal amount to reflect the subsequent transfer of a Certificated  Debenture
to  a Qualified  Institutional Buyer  from a  Regulation S  Purchaser or another
person who is not a Qualified  Institutional Buyer. Transfer of the  Debentures,
whether  as an  interest in  the Rule 144A  Global Debenture  or as Certificated
Debentures, must be made in accordance with the Indenture.
 
PAYMENTS OF PRINCIPAL AND INTEREST
 
    The Indenture requires that payments in respect of the Debentures (including
principal, premium,  if any,  and interest)  held of  record by  DTC  (including
Debentures  evidenced by  the Rule  144A Global Debenture)  be made  in same day
funds. Payments in  respect of the  Debentures held of  record by holders  other
than  DTC may, at the option of the Company, be made by check and mailed to such
holders of record as shown on the register for the Debentures.
 
GOVERNING LAW
 
    The Indenture and  Debentures are  governed by and  construed in  accordance
with  the laws of the  State of New York, without  giving effect to such State's
conflicts of laws principles.
 
INFORMATION CONCERNING THE TRUSTEE
 
    The Company and its subsidiaries  may maintain deposit accounts and  conduct
other banking transactions with the Trustee in the ordinary course of business.
 
REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
    Pursuant  to the Registration  Rights Agreement between  the Company and the
Initial Purchasers, the  Company has  filed with the  Commission a  registration
statement  on  Form  S-3 (the  "Shelf  Registration Statement"),  of  which this
Prospectus is a  part, to cover  resales of Transfer  Restricted Securities  (as
defined below) by the holders thereof who satisfy certain conditions relating to
the   provision  of  information  in  connection  with  the  Shelf  Registration
Statement. For purposes of the foregoing, "Transfer Restricted Securities" means
each Debenture and any underlying share of Common Stock until the date on  which
such  Debenture  or  underlying  share  of  Common  Stock  has  been effectively
registered under the Securities Act and disposed of in accordance with the Shelf
Registration Statement, the date on which such Debenture or underlying share  of
Common  Stock  is distributed  to  the public  pursuant  to Rule  144  under the
Securities Act or on  the date such  Debenture or share of  Common Stock may  be
sold  or transferred pursuant to Rule 144(k)  (or any similar provisions then in
force).
 
                                       18
<PAGE>
    The Registration Rights Agreement provides that if (i) the applicable  Shelf
Registration  Statement is not filed with the  Commission on or prior to 60 days
after the Closing Date, or the  applicable Shelf Registration Statement has  not
been  declared effective by the Commission within 90 days after the Closing Date
or (ii) the  Shelf Registration Statement  shall cease to  be effective  without
being  succeeded immediately by  an additional registration  statement filed and
declared effective  (each such  event referred  to in  clauses (i)  and (ii),  a
("Registration Default"), the Company will pay liquidated damages to each Holder
of  Transfer  Restricted Securities.  The amount  of liquidated  damages payable
during any period during which a Registration Default shall have occurred and be
continuing is that amount which is equal to one-quarter of one percent (25 basis
points) per annum per  $1,000 principal amount of  Debentures or $.07 per  annum
per  share of Common Stock (subject to  adjustment in the event of stock splits,
stock recombinations,  stock  dividends  and  the  like)  constituting  Transfer
Restricted  Securities. All accrued liquidated damages  shall be paid to holders
of Debentures by  wire transfer  of immediately  available funds  or by  federal
funds  check by  the Company  on each  Damages Payment  Date (as  defined in the
Registration Rights Agreement).  Following the cure  of a Registration  Default,
liquidated  damages  will  cease to  accrue  with respect  to  such Registration
Default.
 
    Holders of the Debentures will  be required to make certain  representations
to the Company (as described in the Registration Rights Agreement) in connection
with  the Shelf Registration Statement within the  time periods set forth in the
Registration Rights Agreement in order to have their Debentures and Common Stock
included in the Shelf Registration Statement.
 
    The Company shall cause the Shelf Registration Statement to be effective for
a period of three years from the  effective date thereof or such shorter  period
that  will terminate when each of  the Transfer Restricted Securities covered by
the Registration Statement ceases to be a Transfer Restricted Security.
 
    The foregoing  summary  of certain  provisions  of the  Registration  Rights
Agreement does not purport to be complete and is subject to, and is qualified in
its  entirety  by  reference  to,  the  provisions  of  the  Registration Rights
Agreement. Copies of the  Registration Rights Agreement  are available from  the
Company upon request.
 
ABSENCE OF PUBLIC MARKET
 
    There is no existing market for the Debentures and there can be no assurance
as  to the  liquidity of any  markets that  may develop for  the Debentures, the
ability of the holders to sell their Debentures or at what price holders of  the
Debentures  will be able to sell their  Debentures. Future trading prices of the
Debentures  will  depend  upon  many  factors  including,  among  other  things,
prevailing  interest rates,  the Company's operating  results, the  price of the
Common Stock and the market for similar securities. The Initial Purchasers  have
informed the Company that they intend to make a market in the Debentures offered
hereby;  however, the Initial Purchasers are not obligated to do so and any such
market making  activity may  be terminated  at any  time without  notice to  the
holders  of the Debentures.  See "Registration Rights;  Liquidated Damages." The
Debentures have been designated for trading  in the PORTAL Market; however,  the
Company does not intend to apply for listing of the Debentures on any securities
exchange.
 
                          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, 1996, 10,976,790 shares
of  Common Stock (including  88,572 shares held in  escrow) were outstanding and
held by approximately 950 shareholders of record.
    
 
                                       19
<PAGE>
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. 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 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 Certificate of  Incorporation (as amended, 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.
 
                                       20
<PAGE>
    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.
 
    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
 
                                       21
<PAGE>
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 stockholder.
 
REGISTRATION RIGHTS
 
    In  September 1994, the Company  entered into registration rights agreements
with certain stockholders  in connection with  the issuance of  common stock  to
Shamrock  Investments and the merger of J.P. Cole & Associates, Inc. and Paragon
Ambulatory Surgery,  Inc.  into the  Company.  Under these  registration  rights
agreements,  Shamrock Investments  has the right  to demand  one registration on
Form S-3  of the  shares  of Common  Stock held  by  it. In  addition,  Shamrock
Investments, Charles P. Reilly, Michael E. Gallagher, Jonathan Spees and John P.
Cole have certain "piggy-back" registration rights under the Securities Act with
respect  to  the Common  Stock held  by such  stockholders. Accordingly,  if the
Company proposes to  effect certain  registrations of its  securities under  the
Securities  Act,  the Company  is required  to notify  such stockholders  and to
include in such registration all of the  shares of Common Stock requested to  be
included   by  such  stockholders,  subject  to  the  right  of  an  underwriter
participating in the  offering to limit  the number of  shares included in  such
registration.  The Company shall  not be required  to include such  shares in an
underwriting unless the  holders thereof  enter into  an underwriting  agreement
upon terms and conditions agreed upon by the Company and the underwriter (except
as  to monetary obligations of the  holders not contemplated by the registration
rights agreements).  Any such  stockholders  requesting registration  shall  pay
their  own expenses and  shall bear, on  a pro rata  basis with other requesting
stockholders,  all  incremental  registration  expenses  that  result  from  the
inclusion of such shares in a registration.
 
    The Company may delay, suspend or withdraw any registration or qualification
of  securities required  pursuant to  the registration  rights agreements  for a
period not exceeding 120 days if the  Company determines in good faith that  any
such registration would adversely affect an offering or contemplated offering of
any  securities  of the  Company or  any  other contemplated  material corporate
event. In addition, the Company  shall not be required  to effect more than  one
registration in any twelve-month period in which such stockholders were afforded
the opportunity to register securities.
 
    The  holders of such registration rights,  covering in the aggregate 967,827
shares of Common Stock (including shares  issuable upon the exercise of  options
or  the  conversion of  convertible securities),  may  request that  the Company
include some or  all of the  registrable securities  held by them  in the  Shelf
Registration  Statement. See "Description of  Debentures -- Registration Rights;
Liquidated Damages."
 
                            SELLING SECURITYHOLDERS
 
   
    The following table  sets forth  certain information  as of  March 14,  1996
(except  as otherwise  indicated) as  to the  security ownership  of the Selling
Securityholders. Except as set forth below, none of the Selling  Securityholders
has  had a material relationship with the  Company or any of its predecessors or
affiliates within the past three years.

the  Company by The Depository Trust Company  ("DTC"), IBJ Schroder Bank & Trust
Company, trustee  under  the Indenture,  and  by or  on  behalf of  the  Selling
Securityholders.
 
    Information  concerning the Selling Securityholders  may change from time to
time and will be set forth in Supplements to this Prospectus. As of the date  of
this  Prospectus, the  aggregate principal  amount of  Debentures outstanding is
$69,000,000.
 
    Because the Selling Securityholders may offer all or some of the  Debentures
and  shares  of Common  Stock  issued upon  conversion  thereof 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 Debentures  or shares  of Common  Stock that  will be  held by  the  Selling
Securityholders  after completion of this offering,  no estimate can be given as
to the principal amount  of Debentures or  shares of Common  Stock that will  be
held by the Selling Securityholders after completion of this offering. See "Plan
of Distribution."

                              PLAN OF DISTRIBUTION
 
    The  Debentures  and  the  Shares  are  being  registered  to  permit public
secondary trading of such  securities by the holders  thereof from time to  time
after  the date of this Prospectus. The  Company has agreed, among other things,
to bear all expenses (other than underwriting discounts, selling commissions and
fees and expenses of counsel and other advisors to holders of the Debentures and
the underlying Common Stock) in connection with the registration and sale of the
Debentures and the Conversion Shares covered  by this Prospectus. The holder  of
the  Additional Shares have agreed  to pay their own expenses  and to bear, on a
pro rata basis, with other Selling Securityholders, all investment expenses that
result from the inclusion of the Additional Shares.
 
    The Company  will not  receive any  of  the proceeds  from the  offering  of
Debentures  and the Shares by the  Selling Securityholders. The Company has been
advised by the Selling Securityholders that the Selling Securityholders may sell
all or a portion  of the Debentures  and Shares beneficially  owned by them  and
offered  hereby from time  to time on  any exchange on  which the securities are
listed on  terms to  be  determined at  the times  of  such sales.  The  Selling
Securityholders  may also  make private  sales directly  or through  a broker or
brokers. Alternatively, any of the Selling Securityholders may from time to time
offer the  Debentures or  shares  of Common  Stock  beneficially owned  by  them
through  underwriters, dealers  or agents, who  may receive  compensation in the
form of  underwriting discounts,  commissions or  concessions from  the  Selling
Securityholders  and the purchasers of the  Debentures or shares or Common Stock
from whom  they  may  act  as  agent. The  aggregate  proceeds  to  the  Selling
Securityholders  from  the sale  of  the Debentures  of  shares or  Common Stock
offered by them hereby will be the  purchase price of such Debentures or  shares
of Common Stock less discounts and commissions, if any.
 
    The  Debentures and the Shares may be sold  from time to time in one or more
transactions at  fixed offering  prices, which  may be  changed, or  at  varying
prices  determined at the time of sale or at negotiated prices. Such prices will
be determined by  the holders of  such securities or  by agreement between  such
holders  and  underwriters or  dealers who  may receive  fees or  commissions in
connection therewith.
 
    The outstanding Common  Stock is listed  for trading on  the New York  Stock
Exchange,  and the Shares of Common Stock  have been approved for listing on the
New York Stock Exchange.  The Initial Purchasers have  advised the Company  that
they  are  making  and currently  intend  to  continue making  a  market  in the
Debentures; however, they are not obligated to do so and any such  market-making
may  be discontinued at any  time without notice, in  the sole discretion of the
Initial Purchasers. The  Company does  not intend to  apply for  listing of  the
Debentures on any securities exchange. Accordingly, no assurance can be given as
to  the development of liquidity of any  trading market that may develop for the
Debentures. See "Risk Factors -- No Prior Public Market for the Debentures."
 
    In  order  to  comply  with  the  securities  laws  of  certain  states,  if
applicable,  the Debentures and  Shares will be sold  in such jurisdictions only
through registered  or licensed  brokers  or dealers.  In addition,  in  certain
states  the  Debentures  and  Shares  may not  be  sold  unless  they  have been
registered or qualified for  sale in the applicable  state or an exemption  from
the registration or qualification requirement is available and is complied with.
 
    The Selling Securityholders and any broker and any broker-dealers, agents or
underwriters   that  participate   with  the  Selling   Securityholders  in  the
distribution of the Debentures or the Shares may be deemed to be  "underwriters"
within  the  meaning  of the  Securities  Act,  in which  event  any commissions
received by such broker-dealers, agents or underwriters any profit on the resale
of the  Debentures  or  the  Shares  purchased by  them  may  be  deemed  to  be
underwriting commissions or discounts under the Securities Act.
 
    In  addition, any  securities covered by  this Prospectus  which qualify for
sale pursuant to Rule 144 or Rule 144A  of the Securities Act may be sold  under
Rule 144 or Rule 144A rather than pursuant to
 
                                       27
<PAGE>
this Prospectus. There is no assurance that any Selling Securityholder will sell
any  or  all of  the  Debentures or  Shares  described herein,  and  any Selling
Securityholder may transfer, devise or gift  such securities by other means  not
described herein.
 
    The  Debentures were  originally sold to  Smith Barney Inc.  and Dean Witter
Reynolds Inc. in  December 1995 in  a private placement.  The Company agreed  to
indemnify  and hold  Smith Barney  Inc. and  Dean Witter  Reynolds Inc. harmless
against certain  liabilities  under  the  Securities Act  that  could  arise  in
connection  with the sale of the Debentures by Smith Barney Inc. and Dean Witter
Reynolds Inc.  The Company  and  the Selling  Securityholders are  obligated  to
indemnify  each other against  certain liabilities arising  under the Securities
Act.
 
    The Company will use its best efforts to cause the registration statement to
which this Prospectus relates to become effective as promptly as is  practicable
and  to keep the  registration statement effective  for a period  of three years
from the effective date thereof, or until the Shelf Registration Statement is no
longer required for transfer of the  Debentures or the underlying Common  Stock.
The  Company is permitted  to suspend the  use of this  Prospectus in connection
with the sales of Debentures and Conversion Shares by holders upon the happening
of an event or  if there exists  any fact that makes  any statement of  material
fact  made in this Prospectus untrue or that requires the making of additions to
or changes  in  the  Prospectus in  order  to  make the  statements  herein  not
misleading  until such time  as the Company  advises the Selling Securityholders
that use of  the Prospectus may  be resumed, in  which case the  period of  time
during  which the Company is required to maintain the effectiveness of the Shelf
Registration Statement shall be extended.  Expenses of preparing and filing  the
registration  statement and all  post-effective amendments will  be borne by the
Company.

             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 Debentures. 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 Debentures or shares  of
Common  Stock 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 Debentures or  Common Stock in connection with a  straddle)
who  may be subject to  special rules. This discussion  assumes that each holder
holds the Debentures  and the shares  of Common Stock  received upon  conversion
thereof as capital assets.
 
    For the purpose of this discussion, a "Non-U.S. Holder" refers to any holder
who  is not  a United  States person.  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 THEIR PARTICIPATION IN
THIS OFFERING, OWNERSHIP AND DISPOSITION OF THE DEBENTURES, INCLUDING CONVERSION
OF THE DEBENTURES, AND THE EFFECT  THAT THEIR PARTICULAR CIRCUMSTANCES MAY  HAVE
ON SUCH TAX CONSEQUENCES.
 
OWNERSHIP OF THE DEBENTURES
 
    INTEREST  ON DEBENTURES.  Interest paid on  a Debenture will be taxable to a
holder as ordinary interest income in accordance with the holder's method of tax
accounting  at  the  time  that  such  interest  is  accrued  or  (actually   or
constructively)  received. The Company anticipates  that the Debentures will not
be issued with original issue discount ("OID") within the meaning of the Code.
 
    CONSTRUCTIVE  DIVIDEND.      Certain   corporate   transactions,   such   as
distributions   of  cash  to  holders  of  Common  Stock,  may  cause  a  deemed
distribution to  the  holders of  the  Debentures  if the  conversion  price  or
conversion  ratio  of  the  Debentures is  adjusted  to  reflect  such corporate
transaction. Such deemed distributions will be taxable as a dividend, return  of
capital,  or  capital gain  in accordance  with the  earnings and  profits rules
discussed under "Dividends on Shares of Common Stock."
 
    SALE OR EXCHANGE OF  DEBENTURES OR SHARES  OF COMMON STOCK.   In general,  a
holder  of a Debenture  will recognize gain  or loss upon  the sale, redemption,
retirement or  other disposition  of the  Debenture measured  by the  difference
between  the amount of cash  and the fair market  value of any property received
(except to the extent attributable to  the payment of accrued interest) and  the
holder's  adjusted  tax  basis in  the  Debenture.  A holder's  tax  basis  in a
Debenture generally will equal the cost of the Debenture to the holder increased
by the amount of market  discount, if any, previously  taken into income by  the
holder or decreased by any bond premium theretofore amortized by the holder with
respect  to the Debenture. (For the basis and holding period of shares of Common
Stock, see "Conversion of Debentures.") In general, each holder of Common  Stock
into  which the Debentures have been converted  will recognize gain or loss upon
the sale, exchange, redemption, or other  disposition of the Common Stock  under
rules  similar to those applicable to the Debentures. Special rules may apply to
redemptions of Common Stock which may result in the amount paid being treated as
a dividend. Subject to  the market discount rules  discussed below, the gain  or
loss on the disposition of the
 
                                       29
<PAGE>
Debentures  or shares of Common  Stock will be capital gain  or loss and will be
long-term gain or loss  if the Debentures  or shares of  Common Stock have  been
held for more than one year at the time of such disposition.
 
    CONVERSION  OF DEBENTURES.  A holder of  a Debenture will not recognize gain
or loss on the conversion of the  Debenture into shares of Common Stock,  except
to  the extent that the Common Stock  issued upon the conversion is attributable
to accrued interest on  the Debenture. The holder's  aggregate tax basis in  the
shares  of Common Stock received upon conversion  of the Debenture will be equal
to the holder's aggregate  basis in the Debenture  exchanged therefor (less  any
portion  thereof allocable to cash received in  lieu of a fractional share). The
holding period  of  the shares  of  Common Stock  received  by the  holder  upon
conversion of the Debenture will include the period during which the holder held
the Debenture prior to the conversion.
 
    Cash  received  in lieu  of a  fractional  share of  Common Stock  should be
treated as  a  payment in  exchange  for such  fractional  share. Gain  or  loss
recognized  on  the receipt  of  cash paid  in  lieu of  such  fractional shares
generally will equal the difference between the amount of cash received and  the
amount of tax basis allocable to the fractional shares.
 
    MARKET  DISCOUNT.  The resale of a  Debenture may be affected by the "market
discount" provisions of  the Code. For  this purpose, the  market discount on  a
Debenture  will generally be  equal to the  amount, if any,  by which the stated
redemption price at maturity of the Debenture immediately after its  acquisition
exceeds  the  holder's tax  basis  in the  debenture.  Subject to  a  de minimis
exception, these provisions generally require  a holder of a Debenture  acquired
at  a market  discount to treat  as ordinary  income any gain  recognized on the
disposition of such Debenture to the extent of the "accrued market discount"  on
such  Debenture at  the time  of disposition. In  general, market  discount on a
Debenture will be treated as accruing on a straight-line basis over the term  of
such  Debenture,  or, at  the election  of  the holder,  under a  constant yield
method.
 
    In addition, any holder of a Debenture acquired at a market discount may  be
required to defer the deduction of a portion of the interest on any indebtedness
incurred or maintained to purchase or carry the Debenture until the Debenture is
disposed  of in a taxable transaction. The  foregoing rule will not apply if the
holder elects to include accrued market discount in income currently.
 
    If a holder acquires the Debenture at a market discount and receives  Common
Stock  upon conversion of  the Debenture, the amount  of accrued market discount
with respect to the converted Debenture through the date of the conversion  will
be  treated,  under  regulations  to  be  issued,  as  ordinary  income  on  the
disposition of the Common Stock.
 
    DIVIDENDS ON SHARES  OF COMMON  STOCK.   Distributions on  shares of  Common
Stock will constitute dividends for United States federal income tax purposes to
the  extent of  current or  accumulated earnings and  profits of  the Company as
determined under United States federal income tax principles. Dividends paid  to
holders   that   are   United   States   corporations   may   qualify   for  the
dividends-received deduction.  Individuals,  partnerships, trusts,  and  certain
corporations,  including certain foreign  corporations, are not  entitled to the
dividends-received deduction.
 
    To the extent, if any,  that a holder receives  a distribution on shares  of
Common  Stock  that  would otherwise  constitute  a dividend  for  United States
federal income tax purposes  but that exceeds  current and accumulated  earnings
and  profits  of the  Company,  such distribution  will  be treated  first  as a
non-taxable return  of capital  reducing the  holder's basis  in the  shares  of
Common  Stock. Any  such distribution  in excess  of the  holder's basis  in the
shares of Common Stock will be treated as a capital gain.
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS APPLICABLE TO NON-U.S. HOLDERS
 
    INTEREST ON DEBENTURES.   Generally, interest  paid on the  Debentures to  a
Non-U.S.  Holder will not be subject to United States federal income tax if: (i)
such interest  is not  effectively connected  with  the conduct  of a  trade  or
business  within the  United States by  such Non-U.S. Holder;  (ii) the Non-U.S.
 
                                       30
<PAGE>
Holder does not actually or constructively own  10% or more of the total  voting
power  of all  classes of stock  of the  Company entitled to  vote and  is not a
controlled foreign corporation with respect to  which the Company is a  "related
person"  within the meaning of  the Code; and (iii)  the beneficial owner, under
penalty of perjury, certifies that he or  she is not a United States person  and
provides his or her name and address. If certain requirements are satisfied, the
certification described in paragraph (iii) above may be provided by a securities
clearing  organization,  a  bank,  or  other  financial  institution  that holds
customers' securities in the ordinary course of its trade or business. For  this
purpose,  the holder of  a Debenture would  be deemed to  own constructively the
Common Stock into which it  could be converted. If a  holder is not exempt  from
tax under these rules, he or she will be subject to United States federal income
tax  withholding at a rate  of 30% unless the  interest is effectively connected
with the  conduct of  a  United States  trade or  business,  in which  case  the
interest  will be subject to the United  States federal income tax on net income
that applies to United States persons generally. Non-U.S. Holders should consult
applicable income tax treaties, which may provide different rules.
 
    SALE OR EXCHANGE OF DEBENTURES OR SHARES OF COMMON STOCK.  A Non-U.S. Holder
generally will  not be  subject to  United  States federal  income tax  on  gain
recognized  upon the  sale or  other disposition  (including a  redemption) of a
Debenture or shares of Common Stock received upon conversion thereof  (including
the  receipt of cash in lieu of  a fractional share upon such conversion) unless
(i) the gain is effectively  connected with the conduct  of a trade or  business
within  the United  States by  the Non-U.S.  Holder, or  (ii) in  the case  of a
Non-U.S. Holder who is a nonresident alien individual and holds the Common Stock
as a capital asset, such holder is present in the United States for 183 or  more
days  in the taxable  year and certain  other circumstances are  present. If the
Company is  a "United  States  real property  holding corporation,"  a  Non-U.S.
Holder may be subject to federal income tax with respect to gain realized on the
disposition  of such Debentures or Common Stock, and the proceeds of disposition
would be subject  to withholding. Any  amount withheld pursuant  to these  rules
will  be creditable against such Non-U.S.  Holder's United States federal income
tax liability and may entitle such  Non-U.S. Holder to a refund upon  furnishing
the  required  information to  the  Internal Revenue  Service.  Non-U.S. Holders
should consult  applicable  income tax  treaties,  which may  provide  different
rules.
 
    CONVERSION  OF DEBENTURES.  A Non-U.S.  Holder generally will not be subject
to United States federal income tax on the conversion of a Debenture into shares
of Common Stock.  To the extent  a Non-U.S. Holder  receives cash in  lieu of  a
fractional  share on conversion, such  cash may give rise  to gain that would be
subject to the rules described above with  respect to the sale or exchange of  a
Debenture or Common Stock.
 
    DIVIDENDS  ON SHARES OF COMMON STOCK.  Generally, any distribution on shares
of Common Stock to a  Non-U.S. Holder will be  subject to United States  federal
income  tax withholding  at a  rate of  30% unless  the dividend  is effectively
connected with the conduct of  a trade or business  within the United States  by
the  Non-U.S. Holder, in which  case the dividend will  be subject to the United
States federal income tax  on net income that  applies to United States  persons
generally   (and,  with   respect  to   corporate  holders   and  under  certain
circumstances, the  branch profits  tax). Non-U.S.  Holders should  consult  any
applicable  income  tax  treaties,  which  may  provide  for  a  lower  rate  of
withholding or  other rules  different from  those described  above. A  Non-U.S.
Holder may be required to satisfy certain certification requirements in order to
claim  treaty  benefits or  otherwise  claim a  reduction  of or  exemption from
withholding under the foregoing rules.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    U.S. HOLDERS.   Information reporting  and backup withholding  may apply  to
payments  of  interest or  dividends on  or the  proceeds of  the sale  or other
disposition of the Debentures or shares of Common Stock made by the Company with
respect to certain noncorporate U.S.  holders. Such U.S. holders generally  will
be  subject to backup withholding at a rate  of 31% unless the recipient of such
payment supplies a taxpayer identification number, certified under penalties  of
perjury, as well as certain other
 
                                       31
<PAGE>
information,  or  otherwise establishes,  in the  manner  prescribed by  law, an
exemption from backup withholding. Any amount withheld under backup  withholding
is  allowable as  a credit  against the U.S.  holder's federal  income tax, upon
furnishing the required information.
 
    NON-U.S. HOLDERS.  Generally,  information reporting and backup  withholding
of  United States federal income tax  at a rate of 31%  may apply to payments of
principal, interest and premium (if any) to Non-U.S. Holders if the payee  fails
to  certify that he or she is a Non-U.S.  person or if the Company or any of its
paying agents has actual knowledge that the payee is a United States person.
 
    The 31% backup withholding tax generally will not apply to dividends paid to
foreign holders outside the  United States that are  subject to 30%  withholding
discussed  above or that  are not so  subject because a  tax treaty applies that
reduces  or  eliminates  such  withholding.  In  that  regard,  under  temporary
regulations,  dividends  payable at  an address  located  outside of  the United
States to a foreign holder are not subject to the backup withholding rules.
 
    The payment of the  proceeds on the disposition  of Debentures or shares  of
Common  Stock  to or  through the  United States  office of  a United  States or
foreign broker will be subject  to information reporting and backup  withholding
at  a rate of 31% unless the owner provides the certification described above or
otherwise establishes  an  exemption.  The  proceeds of  the  disposition  by  a
Non-U.S.  Holder of Debentures or shares of Common Stock to or through a foreign
office of a broker will not be  subject to backup withholding. However, if  such
broker  is a U.S. person, a controlled foreign corporation for United States tax
purposes, or a foreign person 50% or more of whose gross income from all sources
for certain periods  is from activities  that are effectively  connected with  a
United  States trade or  business, information reporting  will apply unless such
broker has documentary evidence in its  files of the owner's foreign status  and
has  no  actual  knowledge  to  the  contrary  or  unless  the  owner  otherwise
establishes an exemption. Both backup withholding and information reporting will
apply to the proceeds from such dispositions if the broker has actual  knowledge
that the payee is a U.S. holder.
 
                                 LEGAL MATTERS
 
    The validity of the issuance of the Debentures and 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  year
ended  April 30, 1995, incorporated  by reference in this  Prospectus and in the
Registration Statement from the  Company's 1995 Form 10-K  and Form 8-K/A  dated
January  11, 1996,  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
dated   January  11,  1996  includes  an  explanatory  paragraph  regarding  the
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, 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, 1996, 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
    
 
                                       32
<PAGE>
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 as  of April 30,  1994
and  1993 and for each of the years in the two-year period ended April 30, 1994,
incorporated by reference in this  Prospectus and in the Registration  Statement
from  the Company's 1995 Form 10-K, have  been audited by KPMG Peat Marwick LLP,
independent certified public accountants, as stated in their report incorporated
by reference  herein,  and  upon  the  authority of  said  firm  as  experts  in
accounting and auditing. The consolidated financial statements of the Company as
of  April 30, 1994  and 1993 and  for each of  the years in  the two-year period
ended  April  30,  1994,  incorporated  by  reference  in  this  Prospectus  and
Registration Statement from the Company's Form 8-K/A dated 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 and 1993 consolidated  financial statements and  footnotes thereto for  the
effects  of a 2-for-1 stock split effected as a stock dividend in November 1995,
have been  audited  by  KPMG  Peat Marwick  LLP,  independent  certified  public
accountants, as stated in their report appearing 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 was  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
 
                                      II-1
<PAGE>
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.
 
    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  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.

certifies that  it has  reasonable grounds  to  believe that  it meets  all  the
requirements  of  filing  on Form  S-3  and  has duly  caused  this Registration
Statement to  be  signed  on  its behalf  by  the  undersigned,  thereunto  duly
authorized, in the Town of Reston, Commonwealth of Virginia, on this 18th day of

PHP HEALTHCARE CORPORATION
11440 Commerce Park Drive
Suite 300
Reston, Virginia 20091

Gentlemen:

     We are acting as counsel to PHP Healthcare Corporation, a Delaware
corporation (the "Company"), in connection with the Registration Statement on
Form S-3 (as amended, the "Registration Statement") under the Securities Act of
1933 (the "Act"), covering (i) $69,000,000 aggregate principal amount of 6 1/2%
Convertible Subordinated Debentures due 2002 (the "Debentures") of the Company,
(ii) 2,532,110 shares of Common Stock, par value $.01 per share, of the Company
("Common Stock") initially issuable upon conversion of the Debentures plus an
indeterminate number of shares of Common Stock as may become issuable upon
conversion of the Debentures by means of an adjustment in the conversion price
(the "Conversion Shares"), (iii) 713,858 outstanding shares of Common Stock
issued by the Company to Shamrock Investments and certain former shareholders of
Paragon Ambulatory Surgery, Inc. and J.P. Cole & Associates, Inc. (the "Paragon
Shares"), (iv) 111,111 shares of Common Stock (the "Note Shares") issuable upon
conversion of the Company's Convertible Notes, dated September 29, 1994, in the
aggregate principal amount of $500,000 payable to certain former shareholders of
Paragon Ambulatory Surgery, Inc. (the "Convertible Notes"), and (v) 142,858
shares of Common Stock (the "Option Shares") issuable upon exercise of stock
options granted pursuant to Stock Option Agreements dated October 3, 1994 (the
"Stock Option Agreements") between the Company and certain former stockholders
of J.P. Cole & Associates, Inc.

     In connection with this opinion, we have (i) investigated such questions of
law, (ii) examined originals or certified, conformed or reproduced copies of
such agreements, instruments, documents and records of the Company and its
subsidiaries, such certificates of public officials and such other documents and
(iii) reviewed such information from officers and representatives of the Company
and its subsidiaries and others as we have deemed necessary or appropriate for
the purposes of this opinion.

     In all such examinations, we have assumed the legal capacity of all
natural persons executing documents, the genuineness of all signatures, the
authenticity of all original or certified documents, and the conformity to
original or certified documents of all copies submitted to us as conformed or
reproduced copies.  As to various questions of fact relevant to the opinions
expressed herein, we have relied upon, and assume the accuracy of, the
statements made in the certificate of an officer of the Company (the "Officers'
Certificate") attached hereto as Annex A and certificates and oral or written
statements and other information of or from public officials and officers and
representatives of the Company, its subsidiaries and others.

     To the extent that it may be relevant to the opinion expressed herein, we
have assumed, for purposes of the opinions expressed herein, that (i) the
trustee for the Debentures (the "Trustee") has the power and authority to enter
into and perform the indenture for the Debentures (the "Indenture"), (ii) the
Indenture has been duly authorized, executed and delivered by the Trustee and is
a valid and binding obligation of the Trustee, enforceable against the Trustee
in accordance with its terms, and (iii) the Debentures have been duly
authenticated and delivered by the Trustee.

     Based upon the foregoing, and subject to the limitations, qualifications
and assumptions set forth herein, we are of the opinion that:

     1.   The Debentures have been duly authorized, executed and delivered by
the Company and constitute valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms.

     2.   The Conversion Shares have been duly authorized and, when issued upon
the conversion of the Debentures in accordance with the terms of the Indenture,
will be validly issued, fully paid and non-assessable.

     3.   The Paragon Shares have been duly authorized and validly issued and
are fully paid and nonassessable.

     4.   The Note Shares have been duly authorized, and, when issued upon
conversion of the applicable Convertible Note in accordance with the terms
thereof, will be validly issued, fully paid and non-assessable.

     5.   The Option Shares have been duly authorized, and, when issued upon
exercise of the Options in accordance with the terms of the applicable Stock
Option Agreement, will be validly issued, fully paid and non-assessable.

     The opinions set forth above are subject to:

          (i)    applicable bankruptcy, insolvency, reorganization, moratorium

     generally; and

          (ii)   general principles of equity (including, without limitation,
     standards of materiality, good faith, fair dealing and reasonableness)
     whether such principles are considered in a proceeding in equity or at law.

     The opinions expressed herein are limited to the federal laws of the United
States and the laws of the State of New York and, to the extent relevant hereto,
the Delaware General Corporation Law.

     We hereby consent to the filing of this opinion letter as an exhibit to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the Prospectus forming a part of the Registration Statement.
