                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND FINANCIAL STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN
THIS PROSPECTUS. THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK.
SEE "RISK FACTORS."
 
                                  THE COMPANY
 
    Accredo Health, Incorporated ("Accredo" or the "Company") provides
specialized contract pharmacy and related services beneficial to patients with
certain costly, chronic diseases. Because of the unique needs of patients
suffering from chronic diseases, biotechnology drug manufacturers have
recognized the benefits of customized treatment programs to facilitate alternate
site drug administration, ensure compliance with treatment regimens, provide
reimbursement assistance and capture valuable clinical and patient demographic
information. The Company addresses the needs of the manufacturers by providing
specialized services that facilitate product launch and patient acceptance,
including timely drug utilization and patient compliance information, patient
education and monitoring, reimbursement expertise and overnight drug delivery.
The Company believes that its ability to accelerate market penetration and
increase revenues for new biotechnology drugs makes it the partner of choice for
manufacturers as evidenced by its preferred relationships with Genzyme
Corporation ("Genzyme"), Biogen, Inc. ("Biogen"), Genentech, Inc. ("Genentech")
and Centocor Inc. ("Centocor").
 
    The Company has designed its specialty services to focus primarily on
biotechnology drugs that: (i) are used on a recurring basis to treat chronic and
potentially life threatening diseases; (ii) are expensive, with an annual
therapy cost as high as $200,000 per patient; (iii) are administered through
injection; and (iv) require temperature control or other specialized handling as
part of their distribution process. Currently, the Company provides services
that address the needs of patients with the following diseases: Gaucher Disease,
a hereditary liver enzyme deficiency; hemophilia, a hereditary bleeding
disorder; Multiple Sclerosis, a debilitating disease of the central nervous
system; and growth hormone-related disorders. In addition, the Company has
recently entered into an agreement with Centocor to provide its services to
patients with Crohn's Disease, a chronic inflammatory disease affecting the
gastrointestinal tract. These diseases generally require life-long therapy,
except for growth hormone-related disorders which typically require treatment
for six to ten years.
 
    The Company believes that it is well positioned to take advantage of a large
drug development pipeline and is at the forefront of an increasing trend toward
specialized outsourcing by the biotechnology drug industry. Biotechnology
products represent the most expensive and rapidly growing part of the new drug
pipeline, with an estimated 240 products in late-stage clinical trials as of
mid-1998. The Company continuously monitors biotechnology drugs in various
phases of clinical development with a particular focus on identifying potential
new drugs for the treatment of costly, chronic diseases. Unlike many traditional
drugs, these products often possess specific characteristics that make
utilization and compliance increasingly difficult. They are often composed of
unstable proteins which must be taken by injection and require timely,
temperature maintained distribution, dosage monitoring, and controlled inventory
management. In addition, expert reimbursement management is crucial as a result
of their high cost. When addressing chronic diseases, the challenges facing
biotechnology drug manufacturers are often heightened by small patient
populations and the need for patients to remain on therapy for extended periods.
 
    In response to the challenges facing biotechnology drug manufacturers, which
include often limited resources, the unpredictability of the drug approval
process and the onset of significant competition, many manufacturers have sought
to outsource various stages of product development in order to realize a return
on investment prior to the expiration of any patent or orphan drug status
exclusivity. This has included discovery research by outsourcing genomics and
screening functions and clinical development through the use of contract
research organizations (CROs) and site management organizations (SMOs). This
trend has also extended to product commercialization and launch through the
outsourcing of manufacturing, sales and marketing, product detailing, pharmacy
and distribution services and patient support programs.
 
    The Company's objective is to be the leading provider of specialized
contract pharmacy and related services. Key elements of the Company's strategy
include: (i) expanding the number of chronic diseases served; (ii) leveraging
its expertise to expand its service offerings; (iii) establishing additional
relationships with academic medical centers and children's hospitals that treat
patients with costly, chronic diseases; (iv) increasing its number of payor
contracts; and (v) pursuing acquisitions of similar or complementary businesses.

- ------------------------
 
(1) The Company was incorporated on May 24, 1996. On May 31, 1996, the Company
    acquired Southern Health Systems, Inc. ("SHS"), a holding company, and its
    wholly-owned subsidiary, Nova Factor, Inc. ("Nova Factor" or the
    "Predecessor"). Since the Company was newly formed at May 24, 1996, and
    because the Predecessor had been in existence for several years, the Company
    is considered the successor to the Predecessor's operations. The balance
    sheet data of the Predecessor represents the historical cost basis of the
    Predecessor's assets and liabilities prior to its acquisition by the
    Company. The acquisition of the Predecessor by the Company resulted in a new
    basis of accounting such that the Predecessor's assets and liabilities were
    recorded at their fair value in the Company's consolidated balance sheet
    upon consummation of the acquisition. Additionally, the Company acquired
    Horizon Health Systems, Inc. ("HHS") on June 1, 1997. Accordingly, the
    Summary Financial Data are not strictly comparable for the periods
    presented. See Notes 1 and 3 of Notes to the Company's Consolidated
    Financial Statements.
 
(2) The Predecessor has been allocated expenses for certain services provided by
    its parent, SHS, including cash management, tax reporting, risk management
    and executive management services. Charges for these services were based
    upon a general allocation methodology determined by SHS (used to allocate
    all corporate overhead expenses to SHS subsidiaries), and were not
    necessarily allocated based on specific identification of expenses.
    Management believes the allocation methodology is reasonable. See Note 6 of
    Notes to the Nova Factor, Inc. Financial Statements.
 
(3) As adjusted to reflect the sale of the Common Stock offered hereby at an
    assumed initial public offering price of $        per share and the receipt
    and application of the estimated net proceeds therefrom as if such
    transactions had occurred on June 30, 1998. See "Use of Proceeds" and
    "Capitalization."

OF WHICH CANNOT BE PREDICTED WITH ACCURACY AND SOME OF WHICH MIGHT NOT EVEN BE
ANTICIPATED. FUTURE EVENTS AND ACTUAL RESULTS, FINANCIAL AND OTHERWISE, COULD
DIFFER MATERIALLY FROM THOSE SET FORTH IN OR CONTEMPLATED BY THE FORWARD-LOOKING
STATEMENTS CONTAINED HEREIN. IMPORTANT FACTORS THAT COULD CONTRIBUTE TO SUCH
DIFFERENCES ARE SET FORTH BELOW UNDER "RISK FACTORS" AND ELSEWHERE IN THIS
PROSPECTUS, INCLUDING IN "PROSPECTUS SUMMARY," "MANAGEMENT'S DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" AND "BUSINESS".
 
    DEPENDENCE ON RELATIONSHIPS WITH LIMITED NUMBER OF BIOTECHNOLOGY DRUG
MANUFACTURERS.  The Company's revenue and profitability are highly dependent on
its relationships with a limited number of biotechnology drug companies that
manufacture and supply drugs for the specific chronic diseases served by the
Company. The Company derives a substantial portion of its total revenue from its
relationships with its three largest suppliers, Genzyme, Biogen and Genentech.
For the fiscal year ended June 30, 1998, the Company derived approximately 46%,
23% and 6%, respectively, of its total revenue from its relationships with such
suppliers and approximately 64%, 14% and 9%, respectively, for the fiscal year
ended June 30, 1997. Due to the Company's focus on a limited number of chronic
diseases, the Company is likely to continue to experience a high degree of
concentration of business with several suppliers, which concentration may
increase from continuing consolidation in the biotechnology industry. The
Company's agreements with these suppliers generally limit the Company's ability
to supply competing drugs during (and in some cases for up to five years after)
the term of the agreement, allow the supplier to distribute directly or through
other parties, are generally short term and may be canceled by either party,
without cause, upon between 60 and 90 days prior notice. The Company and its
suppliers periodically adjust the Company's purchase price and other terms for
the drugs covered by such contracts as well as the scope and pricing of services
provided by the Company under such contracts. Any termination, adverse
adjustment of purchase price or other terms, change in the supplier's
distribution methods or adverse change in the Company's relationship with any of
its suppliers (including as a result of consolidation among drug suppliers)
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Disease Markets and
Manufacturer Relationships" and "--Suppliers."
 
    CONCENTRATION OF DRUGS AND CHRONIC DISEASES.  The Company currently focuses
almost exclusively on a limited number of complex and expensive drugs that treat
certain specific chronic diseases: Gaucher Disease, for which the Company offers
Ceredase-Registered Trademark- and Cerezyme-Registered Trademark- supplied by
Genzyme; Multiple Sclerosis, for which the Company primarily offers Biogen's
Avonex-Registered Trademark- (Interferon Beta-1a)
("Avonex-Registered Trademark-"); growth hormone-related disorders, for which
the Company primarily offers Protropin-Registered Trademark-,
Nutropin-Registered Trademark- and Nutropin AQ-Registered Trademark- supplied by
Genentech; and hemophilia, for which the Company offers all currently approved
clotting factor products. In addition, the Company recently entered into a
contract with Centocor to offer Remicade-TM- for the treatment of Crohn's
Disease. For the fiscal year ended June 30, 1998, the Company derived
approximately 46%, 23%, 6% and 23% of its total revenue from providing its
pharmacy services in respect of drugs for Gaucher Disease, Multiple Sclerosis,
growth hormone-related disorders and hemophilia, respectively, and approximately
64%, 14%, 9% and 9%, respectively, for the fiscal year ended June 30, 1997. The
drugs offered by the Company are complex (generally requiring injection, special
handling and patient education), are expensive (with small numbers of patients
representing large amounts of revenue), serve small patient populations in the
United States
 
                                       6
<PAGE>
and, other than drugs for hemophilia and growth hormone-related disorders, are
available only from single sources that generally restrict the Company from
offering competing drugs. As a result, the Company could be materially and
adversely affected by a variety of factors, such as the development of a new
treatment modality not requiring the Company's specialty pharmacy services, an
adverse reaction to or recall of a drug, the expiration of or challenge to a
drug patent, the loss of orphan drug status, the availability of a competing
treatment through a new drug or a new indication for an existing drug, the loss
of a managed care or other payor relationship covering a number of high revenue
patients, a disease cure or the death of a high revenue patient. For example, in
July 1996, Berlex Laboratories, Inc. ("Berlex") filed suit against Biogen
alleging patent infringement by Biogen in the production of
Avonex-Registered Trademark- and seeking, among other things, a permanent
injunction restraining Biogen from such alleged infringement. The granting of a
permanent injunction that restrains Biogen from manufacturing
Avonex-Registered Trademark- or the inability of Biogen to continue to supply
Avonex-Registered Trademark- on terms favorable to the Company could have a
material adverse effect on the Company's business, financial condition and
results of operations. Furthermore, due to the small patient populations of the
diseases serviced by the Company, future growth is highly dependent on the
Company expanding the base of drugs for which it provides its services,
expanding its relationships with its current suppliers and establishing
relationships with new suppliers, none of which can be assured. See
"Business--Disease Markets and Manufacturer Relationships" and "--Suppliers."
 
    DEPENDENCE ON MEDICAL CENTER RELATIONSHIPS.  The Company has certain joint
venture or business management relationships, as applicable, with eight medical
centers (or their affiliates) that involve services related to hemophilia and
growth hormone-related disorders. For the fiscal years ended June 30, 1998 and
1997, the Company derived an aggregate of approximately 22% and 39%,
respectively, of its income before income taxes from its equity in the net
income of these joint ventures, and, in particular, 12% and 24%, respectively,
from the Company's joint venture with Alternative Care Systems, Inc. located in
Dallas, Texas. The Company and each of the medical centers with which it has a
joint venture typically share in the profits and losses of the venture in
proportion to their respective capital contributions, with neither party having
voting control. The agreements with these medical centers are short-term,
ranging between one and five years in duration, and may be cancelled by either
party without cause with between one and twelve months prior notice. Any
termination, adjustment to terms or adverse change in the Company's
relationships with these medical centers, including as a result of consolidation
within the hospital industry, regulatory uncertainties inherent in the structure
of the relationships or restrictive changes to regulatory requirements, could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business--Strategic Relationships with Medical
Centers" and "--Government Regulation."
 
    DEPENDENCE ON BIOTECHNOLOGY DRUG INDUSTRY.  The Company's business is highly
dependent on research, development, manufacturing and marketing expenditures of
biotechnology drug companies and the ability of such companies to develop,
supply and generate demand for drugs that meet the Company's service model. The
Company has benefited to date from the willingness of such companies to
outsource specialty pharmacy services such as those offered by the Company, but
there can be no assurance that this trend will continue. Furthermore, the
Company would be materially and adversely affected by unfavorable developments
in the biotechnology drug industry generally, such as, among other things,
supply shortages, adverse drug reactions, drug recalls, increased competition
among biotechnology drug companies, the inability of drug companies to obtain
capital needed to finance product development, governmental or private market
initiatives to reduce the retail price of drugs, changes in the United States
Food and Drug Administration ("FDA") approval process or governmental or private
initiatives to regulate the manner in which drug manufacturers, health care
providers or pharmacies promote or sell their products and services. Any of
these factors could result in a decline in the development of drugs, a general
decline in research, development and marketing expenditures, a reduction in the
retail price of drugs sold by the Company, a shortage of drugs sold by the
Company or a reduction in the use by drug companies of the specialty pharmacy
services offered by the Company, any of which could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business-- Industry Overview."
 
                                       7
<PAGE>
    DEPENDENCE ON PAYORS AND REIMBURSEMENT RELATED RISKS.  The profitability of
the Company depends on payment and reimbursement from governmental and
nongovernmental third-party payors. The primary trend in the United States
health care industry is toward cost containment. The increasing prevalence of
managed care, centralized purchasing decisions, consolidation among and
integration of health care providers and competition for patients is continuing
to affect pricing, purchasing and usage patterns in health care. Decisions
regarding the use of a particular drug treatment are increasingly influenced by
large private payors, managed care organizations, group purchasing
organizations, pharmacy benefits management companies, regional integrated
delivery systems and similar organizations, and are becoming more economically
focused, with decisions taking into account product cost and whether a product
reduces the overall cost of treatment. For the fiscal years ended June 30, 1998
and 1997, the Company derived approximately 80% and 83%, respectively, of its
gross patient service revenue from private payors (including self-pay), which
included 7% and 10%, respectively, from sales to private physician practices
whose ultimate payor is typically Medicare. Furthermore, many private payors,
including large managed care organizations and some private physician practices,
have recently experienced financial difficulty. There can be no assurance that
the Company will not be adversely affected by cost containment measures exerted
by its third party payors, the influence of such organizations over decisions
regarding the use of drug treatments or the financial inability of any such
payors, including private physician practices, to satisfy their payment
obligations to the Company. See "Business--Payors."
 
    The Company also derives a significant portion of its revenue from
governmental programs such as Medicare and Medicaid. For the fiscal years ended
June 30, 1998 and 1997, the Company received reimbursement payments from federal
and state programs that accounted for approximately 20% and 17%, respectively,
of the Company's gross patient service revenue, excluding sales to private
physician practices whose ultimate payor is typically Medicare. Such programs
are highly regulated and subject to frequent and substantial changes and cost
containment measures. In recent years, changes in these programs have limited
and reduced reimbursement to providers and Congress recently enacted the
Balanced Budget Act of 1997 which establishes a plan to balance the federal
budget by fiscal year 2002 and which includes significant additional reductions
in spending levels for these programs. This legislation also replaced and
relaxed the federal Medicaid payment standard, thereby increasing state
discretion over the financial administration of Medicaid programs. Furthermore,
federal and state proposals are pending that would impose further limitations on
governmental payments and that would increase patient co-payments and
deductibles. Additionally, a number of states are considering legislation
designed to reduce their Medicaid expenditures and provide universal coverage
and additional care for certain populations, including proposals to impose
additional taxes on providers to help finance or expand such programs. Any of
these changes could result in significant reductions in payment levels for drugs
handled and services provided by the Company, which would have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Payors."
 
    VARIATION IN QUARTERLY OPERATING RESULTS; SEASONALITY.  The Company's
results of operations historically have fluctuated on a quarterly basis and can
be expected to continue to be subject to quarterly fluctuations. In particular,
the Company typically increases its operating expenses in anticipation of the
launch of a new drug, and if the new drug does not generate the levels of sales
during the periods anticipated by management, the Company's results in that and
future quarters could be adversely affected. Quarterly results can also
fluctuate as a result of the timing of periodic adjustments to prices and other
terms with the Company's drug suppliers, the accuracy of estimates of resources
required for ongoing programs, the timing and integration of acquisitions,
changes in regulations related to biotechnology companies, physician prescribing
patterns, and general economic conditions, none of which can be adequately
predicted by the Company. Quarterly operating results also fluctuate as a result
of the annual renewal (on a calendar year basis) of deductible and co-payment
requirements, thereby affecting patient ordering patterns in a manner that
creates a seasonal reduction in revenue from existing drug programs for the
Company's third fiscal quarter ending March 31. The Company believes that
quarterly comparisons of its financial results may not necessarily be meaningful
and should not be relied upon as an indication of future performance. In
addition, fluctuations in quarterly results could affect the market price of the
Common Stock in a manner unrelated to the longer term operating performance of
the Company. See
 
                                       8
<PAGE>
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Quarterly Fluctuations and Seasonality."
 
    JOINT VENTURE AND ACQUISITION RISKS.  As part of its strategy, the Company
continually evaluates joint venture and acquisition opportunities. Such
transactions involve numerous risks, including difficulties in the assimilation
of operations, costs incurred in connection with the transaction, diversion of
management's attention from other business concerns, potential loss of key
employees of an acquired company and delays to address regulatory requirements.
There can be no assurance that the Company will complete any future acquisitions
or joint ventures, or that such transactions, if completed, will be integrated
successfully or will contribute favorably to the Company's operations and
financial condition. In addition, acquisitions and joint ventures can expose the
Company to unknown or contingent liabilities of acquired businesses, including
liabilities for failure to comply with health care or reimbursement laws. In May
1996 the Company acquired all of the outstanding capital stock of SHS, which had
four subsidiaries (including Nova Factor), each of which had prior operating
histories in one or more health care businesses. Prior to closing the
acquisition, SHS divested all of its subsidiaries other than Nova Factor.
However, there can be no assurance that the Company will not be held liable for
matters relating to the operations of the divested subsidiaries for periods
prior to the divestiture. In addition, in June 1997, the Company acquired all of
the outstanding capital stock of HHS, which had an extensive operating history.
Liabilities relating to the prior operations of these and other acquired
companies could have a material adverse effect on the Company's business,
financial condition and results of operations. Furthermore, future acquisitions
or joint ventures may result in dilutive issuances of equity securities,
incurrence of additional debt, amortization of expenses related to acquired
goodwill and intangible assets and exposure to unknown or contingent
liabilities, any of which could have a material adverse effect on the Company's
business, financial condition and results of operations. See "The Company."
 
    GOVERNMENT REGULATION.  The conduct of marketing, selling and purchasing
drugs and medical supplies by and among manufacturers, distributors, health care
providers and patients is extensively regulated and periodically scrutinized by
state and federal governments for compliance with laws and regulations
regarding, among other things, inducements for referrals, prohibited financial
relationships with physicians, joint venture and management arrangements,
product discounts, incentives to patients and professional licensure. This
regulatory framework is complex and the laws are very broad in scope, subject to
differing interpretations and lack substantive court decisions addressing many
arrangements under which the Company has conducted and expects to conduct its
business. Any failure to comply or alleged failure to comply with applicable
laws and regulations could have a material adverse effect on the Company's
business, financial conditions and results of operations. See
"Business--Government Regulation."
 
    In particular, federal and state governments enforce a federal statute that
prohibits the offer, payment, solicitation or receipt of any remuneration,
directly or indirectly, overtly or covertly, to induce or in exchange for the
referral of patients covered by certain governmental programs, or the leasing,
purchasing, ordering or arranging for or recommending the lease, purchase or
order of any item, good, facility or service covered by such programs (the
"Anti-Kickback Law"). The Health Insurance Portability and Accountability Act of
1996 ("HIPAA") greatly expanded the prohibitions of the Anti-Kickback Law by
applying them to almost all health care programs that receive federal funding,
creating new violations for certain fraudulent activity applicable to both
public and private "health care benefit programs" and prohibiting inducements to
Medicare or Medicaid eligible patients. The Company is also subject to the
Ethics in Patient Referrals Act of 1989, as amended, commonly referred to as the
"Stark Law," which prohibits physician referrals for certain health-related
items, including those offered by the Company, to entities with which the
physician or an immediate family member has a "financial relationship," and
prohibits the recipient of any such referral from billing for the referred item.
Violations of these laws are punishable by civil sanctions, including
significant monetary penalties and exclusion from participation in the Medicare
and Medicaid programs, and criminal sanctions in the case of the Anti-Kickback
Law and HIPAA. Due to the breadth and complexity of these laws, there can be no
assurance that the Company, any of its personnel, or any significant customer or
business partner of the Company, will not become subject to sanctions that could
have a material adverse effect on the Company's business, financial condition
and
 
                                       9
<PAGE>
results of operations. Additionally, the sanctioning or exclusion of a
manufacturer or recipient of the Company's products or services, even for
activities unrelated to those of the Company, could also have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Government Regulation."
 
    In an attempt to clarify which arrangements are not subject to prosecution
under the Anti-Kickback Law, the Department of Health and Human Services
("DHHS") adopted certain "safe harbor" regulations and continues to publish
clarifications to such safe harbors. Arrangements that comply with all the
requirements of all applicable safe harbors are deemed not to violate the
Anti-Kickback Law. Several of the Company's business arrangements, such as joint
venture and management arrangements with medical centers, service arrangements
with physicians and product discount arrangements with its suppliers, do not
satisfy all of the requirements necessary to fall within the applicable safe
harbor. Furthermore, the Office of the Inspector General ("OIG") of DHHS has
published certain proposed regulations under HIPAA outlining certain permissible
patient incentives designed to promote preventative care or that are DE MINIMIS
under the HIPAA prohibition against beneficiary inducements. The Company
routinely provides certain items and services to its patients that may not fit
within the proposed regulation. It is possible that some of the Company's
practices could be challenged. Although failure of a transaction or arrangement
to fit within a specific safe harbor provision or the proposed regulation for
beneficiary inducements does not necessarily mean that the transaction or
arrangement is illegal or that prosecution will be pursued, there can be no
assurance that the Company's practices will not be challenged, or that the
Company will not be subject to sanctions or be required to alter or discontinue
certain of its practices, any of which could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Business--Government Regulation."
 
    State laws prohibit the practice of medicine, pharmacy and nursing without a
license. For example, many states interpret the practice of nursing to include
health teaching, health counseling, the provision of care supportive to or
restorative of life and well being and the administration of medical regimens
prescribed by a physician. Accordingly, to the extent that the Company assists
patients and providers in helping patients to comply with prescribed treatment
programs, such activities could be deemed by a state to be the practice of
medicine, pharmacy or nursing. There can be no assurance that the Company's
operations will not be challenged as constituting the unlicensed practice of
medicine or nursing or being outside the scope of its licensed pharmacists or
pharmacy licenses. If such a challenge were made successfully in any state, the
Company and its personnel could be subject to civil and criminal penalties under
such state's law and the Company could be required to reduce, restructure,
outsource or cease its business in that state. See "Business--Government
Regulation."
 
    Significant public attention recently has been focused on the health care
industry due to ongoing federal and state investigations related to among other
things joint ventures, referral and billing practices, product discount
arrangements, home health care services, dissemination of confidential patient
information, clinical drug research trials and gifts for patients. In addition,
state and federal agencies have initiated billing review projects in certain
states and are expected to extend such projects to additional states, including
states in which the Company does business. These enforcement actions increase
the likelihood of governmental investigations of the Company, its affiliates and
their respective predecessors and personnel, and parties with whom it conducts
business, and there can be no assurance that governmental investigators will not
take positions that are inconsistent with industry practices, including the
Company's or such other parties' practices. In addition to investigations and
enforcement actions by governmental agencies, QUI TAM (or "whistleblowers")
actions may be brought under the False Claims Act by private individuals on
behalf of the government. Because the health care industry will continue to be
subject to substantial regulation, there can be no assurance that the Company's
activities will not be challenged or that the Company will not be subject to
sanctions or be required to alter or discontinue certain of its practices, any
of which could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Government
Regulation."
 
    POSSIBLE HEALTH CARE REFORM.  Health care reform measures have been
considered by Congress and other federal and state bodies during recent years.
The intent of the proposals generally has been to reduce health care
 
                                       10
<PAGE>
costs and the growth of total health care expenditures, to expand health care
coverage for the uninsured and to eliminate fraud, waste and financial abuse.
Although comprehensive health care reform has been considered, only limited
proposals have been enacted. Comprehensive health care reform may be considered
again and efforts to enact reform bills are likely to continue. Implementation
of government health care reform may adversely affect development and marketing
expenditures by biotechnology companies, which could decrease the business
opportunities available to the Company or the demand for its specialty services.
The Company is unable to predict the likelihood of such legislation or similar
legislation being enacted into law or the effects that any such legislation
would have on the Company.
 
    MANAGEMENT OF GROWTH.  The Company's business has grown rapidly in its last
two fiscal years with total revenue increasing from $115.2 million in fiscal
year 1997 to $181.0 million in fiscal year 1998. This growth has resulted in a
substantial increase in the number of its employees (from 203 at June 30, 1997
to 271 at June 30, 1998), the size of its programs and the scope of its
operations. This growth has placed and, if such growth continues, will continue
to place a strain on operational, human and financial resources. The Company's
ability to manage such growth effectively will depend upon its ability to
enhance its management team and its ability to attract and retain skilled
employees. The Company's success will also depend on the ability of its officers
and key employees to continue to implement and improve its operational,
management information and financial control systems, and to expand, train and
manage its work force. There can be no assurance that the Company will be able
to manage any future growth successfully or provide the necessary resources to
successfully manage its business. Failure to manage growth effectively could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
    COMPETITION; INDUSTRY CONSOLIDATION.  The specialty pharmacy industry is
highly competitive and is experiencing both horizontal and vertical
consolidation. All of the drugs, supplies and services that the Company provides
are available from sources other than the Company. Current and potential
competitors of the Company include specialty pharmacy divisions of wholesale
drug distributors; specialty pharmacy distributors; pharmacy benefit management
companies; hospital-based pharmacies; retail pharmacies; home infusion therapy
companies; comprehensive hemophilia treatment centers; and other alternate site
health care providers. In addition, the Company's drug suppliers or their
competitors have developed and may continue to develop and implement their own
direct specialty pharmacy service programs in lieu of using the Company. In
addition, managed care companies, pharmacy benefit managers and other payors can
influence the source from which their enrollees may obtain drugs through
required formularies and may desire to use full-line providers on their provider
panels. Many of the Company's competitors and potential competitors have greater
financial, technical, marketing and managerial resources than the Company.
Furthermore, certain of the Company's competitors, such as hospitals and certain
hemophilia treatment centers, are eligible for federally mandated discounts for
drug purchases that are not available to the Company. There are relatively few
barriers to entry into the Company's specialty contract pharmacy service segment
and there can be no assurance that, as the segment continues to evolve,
additional competitors with greater resources than the Company will not enter
the market or that the Company's suppliers will not choose to provide such
specialty services directly or through other businesses that have a broader
range of sales, marketing and support services. There can be no assurance that
competitive pressures will not increase, including as a result of further
industry consolidation, or that such pressures will not have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Competition."
 
    RELIANCE ON TELEPHONE AND COMPUTER SYSTEMS; YEAR 2000 COMPLIANCE
RISK.  Because the Company believes that its success depends, in part, upon its
services provided over the telephone on a real-time basis, any continuing
disruption in either its computer system or its telephone system could adversely
affect its ability to receive and process customer orders, provide its service
to patients and ship products on a timely basis, and could adversely affect the
Company's relations with its patients and suppliers.
 
    Many currently installed computer systems and software products are coded to
accept only two-digit entries in the date code field. By the year 2000, these
date code fields will need to accept four-digit entries to
 
                                       11
<PAGE>
distinguish 21st century dates from 20th century dates. Computer systems that do
not accept four-digit entries could fail or produce erroneous results and cause
disruptions of operations. As a result, many software and computer systems may
need to be upgraded or replaced in order to comply with such "year 2000"
requirements. The Company is in the process of obtaining written verification
from vendors to determine whether the Company's computer systems and software
products are year 2000 compliant. Also, the Company is upgrading its pharmacy
management systems, including its billing and accounts receivable systems, to
address year 2000 issues. The failure of the Company's systems to be year 2000
compliant could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000 Issue."
 
    In addition, the Company has ongoing relationships with third-party payors,
suppliers, vendors, and others that may have computer systems with year 2000
problems that the Company does not control. There can be no assurance that the
Company's payors, including the fiscal intermediaries and governmental agencies,
with which the Company transacts business and which are responsible for payment
to the Company will not experience significant problems with year 2000
compliance. According to testimony before a U.S. House of Representatives
subcommittee, HCFA, which administers the Medicare and Medicaid programs, is far
behind in remedying year 2000 problems, which could delay payment of claims to
providers. The failure of third parties to remedy year 2000 problems could have
a material adverse effect on the Company's business, financial condition and
results of operations.
 
    RISKS RELATED TO SHIPPING.  The Company ships most of its orders by
overnight delivery, and typically bears the cost of shipment. Shipping is a
significant expense in the operation of the Company's business and principally
all of the Company's products are shipped by a single carrier, Federal Express
Corporation ("FedEx"). Accordingly, any significant increase in shipping rates
could have an adverse effect on the Company's results of operations. Similarly,
strikes or other service interruptions by FedEx, or by any other carrier that
may indirectly affect FedEx, would adversely affect the Company's ability to
deliver products on a timely basis and therefore its ability to generate
revenue. The drugs shipped by the Company require special handling, including
refrigeration to maintain temperatures within certain ranges. The Company does
not maintain insurance against product spoilage during shipment. Due to their
high cost, even small shipments of the Company's products can represent
significant dollar amounts of inventory. Accordingly, the spoilage of one or
more shipments of the Company's products could have a material adverse effect on
the Company's results of operations.
 
    DEPENDENCE ON KEY PERSONNEL.  The Company depends on a number of key
executives, the loss of the services of which could have a material adverse
effect on the Company. The Company does not maintain "key person" life insurance
policies on any of its executives. The Company also depends on its ability to
attract and retain qualified professional (including pharmacists) and technical
operating staff. There can be no assurance that the Company will be able to
continue to attract and retain such personnel, and its inability to do so could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
    NEED FOR FINANCING.  In order to implement its growth strategy, the Company
will require substantial capital resources and will need to maintain its
existing capital resources and incur, from time to time, additional short- and
long-term indebtedness, including purchasing terms from its suppliers. The
Company also may need to issue, in public or private transactions, equity or
debt securities, the terms of which will depend on market and other conditions.
There can be no assurance that existing or additional financing will be
available on terms acceptable to the Company, if at all. As a result, the
Company may not be able to implement fully its growth strategy. In addition, any
such financing may result in dilutive issuances of equity securities. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
    RISKS RELATED TO INTANGIBLE ASSETS.  The formation of the Company by WCAS
VII and certain of its affiliates (collectively, "Welsh Carson") and the
subsequent acquisitions by the Company of SHS and HHS have resulted in the
recording of a significant amount of goodwill on the Company's financial
statements. As of June 30, 1998, the Company had goodwill, net of accumulated
amortization, of approximately $56.7 million, or 48% of total assets. Goodwill
arises when an acquiror pays more for a business than the fair value of the
tangible
 
                                       12
<PAGE>
and separately measurable intangible net assets. Generally accepted accounting
principles require that goodwill and all other intangible assets be amortized
over the period benefited by such assets. Management has determined that period
to be no less than 40 years for goodwill and, therefore, the Company amortizes
goodwill on a straight line basis over a period of 40 years. In addition, the
Company's growth strategy will likely result in additional goodwill on the
Company's financial statements. There can be no assurance that the value of
goodwill will ever be realized by the Company. On an on-going basis, the Company
makes an evaluation to determine whether events and circumstances indicate that
all or a portion of the carrying value of goodwill may no longer be recoverable,
in which case a charge to earnings may be necessary to write off unrecoverable
goodwill. Any future determination requiring the write-off of a significant
portion of goodwill could have a material adverse effect on the Company's
business, financial condition and results of operations. See Note 3 of Notes to
the Company's Consolidated Financial Statements.
 
    POTENTIAL LIABILITY; AVAILABILITY OF INSURANCE.  The Company's business
exposes it to risks inherent in the provision of drugs and related services.
Although the Company currently maintains professional liability insurance, there
can be no assurance that the scope of coverage or limits of such insurance will
be adequate to protect it against future claims. In addition, there can be no
assurance that the Company will be able to maintain adequate liability insurance
in the future on acceptable terms or with adequate coverage against potential
liabilities.
 
    CONTROL BY AND USE OF PROCEEDS TO BENEFIT EXISTING STOCKHOLDERS.  Upon the
completion of this Offering, the Company's directors and executive officers and
their affiliates as a group (including shares held by Welsh Carson) will
beneficially own approximately   % of the outstanding voting Common Stock (or
approximately   % if the Underwriters' over-allotment option is exercised in
full). As a result, these stockholders, if acting together, will have effective
control over the Company through their ability to control the election of
directors and all other matters that require a vote by the Company's
stockholders. Such control by the existing stockholders may have the effect of
preventing a change in control of the Company. The existing stockholders'
ability to prevent such a change in control of the Company may have an adverse
effect on the market price of the Common Stock. See "Management--Directors and
Executive Officers," "Principal Stockholders," and "Description of Capital
Stock."
 
    The Company will use a portion of the net proceeds from this Offering to
redeem all outstanding shares of Series A Preferred Stock and to prepay in full
all principal and accrued interest on the Company's outstanding 10% Senior
Subordinated Notes due June 1, 2004 (the "Senior Subordinated Notes"). Welsh
Carson owns approximately 97% of the outstanding shares of Series A Preferred
Stock and substantially all outstanding Senior Subordinated Notes. In addition,
certain executive officers and directors of the Company own, in the aggregate,
approximately 2% of the outstanding shares of Series A Preferred Stock. See "Use
of Proceeds" and "Certain Transactions."
 
    NO PRIOR TRADING MARKET; POTENTIAL VOLATILITY OF STOCK PRICE.  Prior to the
Offering, there has been no public market for the Common Stock, and there can be
no assurance that an active trading market for the Common Stock will develop or,
if one does develop, that it will be maintained. The initial public offering
price, which will be established by negotiations between the Company and the
representatives of the Underwriters, may not be indicative of prices that will
prevail in the trading market for the Common Stock. The market price of the
Common Stock could be subject to wide fluctuations in response to variations in
operating results from quarter to quarter, changes in earnings estimates by
analysts, market conditions in the industry and general economic conditions.
Furthermore, the stock market has experienced significant price and volume
fluctuations unrelated to the operating performance of particular companies.
These market fluctuations may have an adverse effect on the market price of the
Common Stock.
 
    SHARES ELIGIBLE FOR FUTURE SALE.  Sales of substantial amounts of Common
Stock in the public market, or the perception that such sales might occur, could
have a material adverse effect on the market price of the Common Stock.
Immediately following the Offering, the Company will have outstanding
shares of Common Stock (     shares if the Underwriters' over-allotment option
is exercised in full), excluding      shares reserved
 
                                       13
<PAGE>
for issuance upon the exercise of outstanding stock options. The      shares of
Common Stock offered hereby (     if the Underwriters' over-allotment option is
exercised in full) will be eligible for public sale without restriction under
the Securities Act by persons other than affiliates (as that term is defined in
Rule 144 under the Securities Act) of the Company. All of the remaining
     shares of Common Stock outstanding will be "restricted" within the meaning
of Rule 144 and may not be resold in the absence of registration under the
Securities Act or the availability of an exemption from such registration,
including the exemption provided by Rule 144. Taking into consideration the
effect of the 180-day "lock-up" agreements described herein (covering an
aggregate of      shares and options to purchase an additional      shares held
by executive officers, directors and certain existing stockholders of the
Company), approximately      restricted shares of Common Stock will be eligible
for sale in the public market immediately after the Offering and all
remaining restricted shares will be eligible for sale upon the expiration of the
180-day lock-up agreements, in each case subject to certain volume and other
limitations of Rule 144. Holders of      restricted shares of Common Stock have
contractual rights to have those shares registered for resale to the public. If
such holders, by exercising their registration rights after the 180-day lockup
period, cause a large number of shares to be registered and sold in the public
market, the market price of the Common Stock might be adversely affected.
 
    The Company intends to register on Form S-8 under the Securities Act, as
soon as practicable on or after the effective date of the Offering,      shares
of Common Stock reserved for issuance under the Company's stock option and
employee stock purchase plans. This registration statement will be effective
upon filing. Shares registered and issued pursuant to such registration
statement will be freely tradable except to the extent that the holders thereof
are deemed to be affiliates of the Company, in which case the transferability of
such shares will be subject to the volume limitations of Rule 144. Options for
the purchase of      shares of Common Stock are currently outstanding under the
Company's stock option plans. See "Shares Eligible for Future Sale."
 
    ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER, BYLAW AND OTHER
PROVISIONS.  Certain provisions of the Company's Amended and Restated
Certificate of Incorporation and Amended and Restated Bylaws, including the
classification of the Board of Directors into three classes, could have the
effect of making it more difficult for a third party to acquire, or of
discouraging a third party from attempting to acquire, control of the Company.
Such provisions could limit the price that certain investors might be willing to
pay in the future for shares of the Common Stock. Certain of such provisions
allow the Company to issue preferred stock with rights senior to those of the
Common Stock and impose various procedural and other requirements which could
make it more difficult for stockholders to effect certain corporate actions. In
addition, the Company is subject to the provisions of Section 203 of the
Delaware General Corporation Law ("DGCL"), which restricts certain business
combinations with any "interested stockholder" and may delay, defer or prevent a
change in control of the Company. See "Description of Capital Stock."
 
    IMMEDIATE AND SUBSTANTIAL DILUTION.  The purchasers of shares of Common
Stock pursuant to the Offering will experience immediate and substantial
dilution of the net tangible book value per share of Common Stock from the
initial public offering price. At an assumed initial public offering price of
$        per share, purchasers in the Offering will incur dilution of $
per share. See "Dilution."
 
    ABSENCE OF DIVIDENDS.  The Company has not and does not expect to declare or
pay any cash dividends in the foreseeable future. The Company intends to retain
all earnings, if any, in order to expand its operations. Furthermore, the
Company's bank credit agreement presently prohibits the payment of cash
dividends. The payment of cash dividends, if any, in the future is within the
discretion of the Company's Board of Directors and will depend upon the
Company's earnings, if any, capital requirements, financial condition, credit
agreements and other relevant factors. See "Dividend Policy."

                                  THE COMPANY
 
    Accredo provides specialized contract pharmacy and related services
beneficial to patients with certain costly, chronic diseases. Accredo's business
was founded in 1985 by Le Bonheur Health Systems, Inc., the former parent of a
not-for-profit children's hospital in Memphis, Tennessee ("Le Bonheur"). Le
Bonheur operated the business through its subsidiary, Southern Health Systems,
Inc. ("SHS"), and through Nova Factor, Inc., one of four subsidiaries of SHS
("Nova Factor"). In May 1996, Accredo (formerly known as Nova Holdings, Inc.)
was formed to acquire SHS and Nova Factor following the divestiture by SHS of
all of its subsidiaries other than Nova Factor. Accredo continues to own SHS as
a wholly owned subsidiary, and SHS continues to own Nova Factor as a wholly
owned subsidiary. In June 1997, Accredo acquired all of the outstanding stock of
Horizon Health Systems, Inc. (d/b/a Hemophilia Health Services) ("HHS"), which
became and continues to be a wholly owned subsidiary of Accredo. See "Risk
Factors--Joint Venture and Acquisition Risks" and Note 3 of Notes to the
Consolidated Financial Statements of the Company.
 
    The Company's principal executive offices are located at 1640 Century Center
Parkway, Suite 101, Memphis, Tennessee 38134, and its telephone number is (901)
385-3688.
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the      shares of Common
Stock offered hereby at an assumed initial public offering price of $        per
share, after deducting underwriting discounts and commissions and estimated
offering expenses payable by the Company, are estimated to be $        ($     if
the Underwriters' over-allotment option is exercised in full).
 
    The Company expects to use the net proceeds it receives from the Offering as
follows: (i) approximately $   million will be used to repay a portion of the
Company's outstanding indebtedness under its existing Loan and Security
Agreement with NationsBank of Tennessee, N.A. and First Tennessee Bank National
Association (the "Credit Agreement"); (ii) approximately $11.0 million will be
used to prepay in full all principal and accrued interest on the Company's
outstanding Senior Subordinated Notes; (iii) approximately $31.0 million will be
used to redeem all outstanding shares of Series A Preferred Stock, including all
accrued dividends thereon; and (iv) the balance will be used for working capital
and other general corporate purposes, including possible acquisitions. Pending
such uses, the balance of the net proceeds will be invested in short term,
investment grade, interest bearing obligations. The Company from time to time
considers various acquisition proposals, but currently has no commitments or
agreements with respect to any material acquisitions.
 
    The Credit Agreement provides that borrowings thereunder will bear interest
at the prime rate or the London Interbank Offered Rate ("LIBOR") plus, in each
case, a margin depending on the Company's ratio of funded debt to cash flow. The
Company has entered into an interest rate swap agreement with NationsBank of
Tennessee, N.A. to hedge against floating rate interest risk with respect to
amounts of up to $15.0 million outstanding under the Credit Agreement.
Accordingly, as of June 30, 1998, the effective interest rate on the first $15.0
million outstanding under the Credit Agreement was 8.15% per annum, and the
effective interest rate on borrowings in excess of $15.0 million under the
Credit Agreement was 7.625% per annum. All outstanding principal and interest on
borrowings under the Credit Agreement must be paid in full by October 31, 1999.
 
    The Senior Subordinated Notes bear interest at 10.0% per annum and mature on
June 1, 2004. The Series A Preferred Stock accrues dividends at an annual rate
of $8.00 per share. Such dividends are cumulative and accrue from the date of
issue. The mandatory redemption date of the Series A Preferred Stock is May 31,
2004.
 
                                DIVIDEND POLICY
 
    The Company has never declared or paid any cash dividends on its Common
Stock. The Company intends to retain any future earnings to finance the growth
and development of its business and therefore does not anticipate paying any
cash dividends in the forseeable future. The payment of cash dividends in the
future will be at the discretion of the Board of Directors and will depend upon
factors such as the Company's earnings levels, capital requirements, financial
condition and other factors deemed relevant by the Board of Directors. There can
be no assurance that the Company will pay any dividends in the future.

                                 CAPITALIZATION
 
    The following table sets forth as of June 30, 1998 (i) the actual
capitalization of the Company and (ii) the pro forma capitalization of the
Company as adjusted to give effect to (a) the exchange by WCAS VII of
shares of Common Stock for         shares of Non-Voting Common Stock pursuant to
the Recapitalization and (b) the sale by the Company of      shares of Common
Stock in the Offering at an assumed initial public offering price of $
per share and the application of the estimated net proceeds therefrom (after
deducting underwriting discounts and commissions and estimated offering expenses
payable by the Company). This table should be read in conjunction with the
Company's Consolidated Financial Statements and Notes thereto included elsewhere
in this Prospectus.

                                    DILUTION
 
    As of June 30, 1998, the Company's net deficit in tangible book value was
$        , or $  per share of Common Stock. Net deficit in tangible book value
per share represents the amount of the Company's total tangible assets, less
total liabilities and mandatorily redeemable cumulative preferred stock, divided
by the number of shares of Common Stock outstanding. After giving effect to the
sale by the Company of      shares of Common Stock in the Offering at an assumed
initial public offering price of $  per share and after deducting underwriting
discounts and commissions and estimated offering expenses payable by the
Company, the pro forma net tangible book value of the Company as of June 30,
1998 would have been approximately $        , or $  per share. This represents
an immediate increase in net tangible book value of $  per share to existing
stockholders and an immediate dilution in net tangible book value of $  per
share to new investors. The following table illustrates this per share dilution:

(1) The Company was incorporated on May 24, 1996. On May 31, 1996, the Company
    acquired SHS, a holding company, and its wholly-owned subsidiary, Nova
    Factor (the "Predecessor"). Since the Company was newly formed at May 24,
    1996, and because the Predecessor had been in existence for several years,
    the Company is considered the successor to the Predecessor's operations. The
    balance sheet data of the Predecessor represents the historical cost basis
    of the Predecessor's assets and liabilities prior to its acquisition by the
    Company. The acquisition of the Predecessor by the Company resulted in a new
    basis of accounting such that the Predecessor's assets and liabilities were
    recorded at their fair value in the Company's consolidated balance sheet
    upon consummation of the acquisition. Additionally, the Company acquired HHS
    on June 1, 1997. Accordingly, the Selected Financial Data are not strictly
    comparable for the periods presented. See Notes 1 and 3 of Notes to the
    Company's Consolidated Financial Statements.
 
(2) On July 1, 1994, the Predecessor was assigned contractual rights from a
    subsidiary of SHS relating to the distribution of certain drugs.
 
(3) The Predecessor has been allocated expenses for certain services provided by
    its parent, SHS, including cash management, tax reporting, risk management
    and executive management services. Charges for these services were based
    upon a general allocation methodology determined by SHS (used to allocate
    all corporate overhead expenses to SHS subsidiaries), and were not
    necessarily allocated based on specific identification of expenses.
    Management believes the allocation methodology is reasonable. See Note 6 of
    Notes to the Nova Factor, Inc. Financial Statements.
 
(4) In May 1996, the Predecessor settled various intercompany accounts with
    subsidiaries of SHS.

treatment of patients with certain costly, chronic diseases. The Company derives
revenues primarily from the sale of biotechnology drugs to patients.
Historically, the majority of the Company's revenues have been derived from
products and services provided with respect to four diseases: Gaucher Disease,
hemophilia, Multiple Sclerosis and growth hormone-related disorders. The
products provided by the Company are purchased directly from biotechnology drug
manufacturers pursuant to preferred relationship agreements in the case of
Gaucher Disease, Multiple Sclerosis, and growth hormone-related disorders and
purchase agreements in the case of hemophilia. Approximately 46%, 23% and 6% of
Accredo's total revenues in fiscal 1998 were generated from sales and services
provided with respect to Gaucher Disease, Multiple Sclerosis and growth
hormone-related disorders, respectively, and which sales and services were (and
will continue to be) dependent upon the Company's preferred relationships with
Genzyme, Biogen and Genentech, respectively. Sales and services provided with
respect to hemophilia represented approximately 23% of the Company's total
revenues in 1998.
 
    The Company's preferred relationship agreements describe certain services to
be provided by the Company, including contract pharmacy, information, clinical,
reimbursement and customized delivery services. The agreements generally limit
the Company's ability to supply competing drugs during (and in some cases for up
to five years after) the term of the agreement, allow the manufacturer to
distribute directly or through other parties, are generally short term and may
be cancelled by either party, without cause, upon between 60 and 90 days prior
notice. The agreements vary in level of exclusivity and scope of services
provided. The Company typically purchases products at prices below the
manufacturers' average wholesale sales prices, and the Company's resulting
contribution margins vary for each product line. Pricing is customized to
reflect specific services to be provided by Accredo and is subject to periodic
adjustments to reflect changing market conditions.
 
    The Company recognizes revenue at the time the biotechnology drug is
dispensed or when the contractual service has been performed. While the Company
may experience some revenue changes from price fluctuations on its existing
product lines, its revenue growth will depend principally on the introduction of
new drugs and to a lesser extent on volume growth in existing drug lines. In May
1996, the Company entered into a preferred relationship with Biogen and
initiated sales and services with respect to Avonex-Registered Trademark- for
the treatment of Multiple Sclerosis. In August 1998, the Company entered into a
preferred relationship with Centocor and will initiate sales and services with
respect to Remicade-TM- for the treatment of Crohn's Disease. Although the
introduction of new drugs is dependent on the regulatory approval process,
management believes the pipeline of biotechnology drugs for which the Company's
services may be utilized will continue to expand.
 
    In response to growing demand, the Company has expanded its existing
relationships with biotechnology manufacturers through the development of new or
complementary services that fit the specialized needs of the manufacturer and
the patients they serve. For example, the Company recently implemented a
referral triage service to provide a convenient single source for prescribing
physicians and help manufacturers increase market penetration. These services
have provided an additional source of revenue for the Company in fiscal 1998 and
 
                                       19

1997, and management believes that the need for additional services will
continue to expand and will constitute an increasing percentage of the Company's
revenues in the future.
 
    In addition to new services, Accredo may also grow through strategic
acquisitions and joint ventures. The acquisition of HHS in June 1997 enabled the
Company to significantly increase its presence in the hemophilia market.
Subsequent to the acquisition, the Company consolidated its existing hemophilia
operations into HHS to take advantage of volume purchasing discounts, disease
management systems and increased access to certain state Medicaid and managed
care relationships.
 
    Accredo has four joint venture agreements with various medical centers (or
their affiliates) in which the Company owns 50% or less of the venture. Many of
the Company's patient populations have diseases that are discovered before or
during adolescence and require on-going care from physician specialists, many of
whom are based at pediatric, academic and other acute care medical centers. To
date, these ventures have primarily derived revenues from the treatment of
patients with hemophilia and growth hormone-related disorders. The Company and
its joint venture partners share profits and losses in equal proportion to their
respective equity ownership. The Company accounts for its interests in the net
income or loss in these joint ventures under the equity method of accounting.
The Company's equity interest in the net income of these joint ventures
represented approximately 22% of the Company's income before income taxes for
fiscal 1998. In addition to joint venture relationships, the Company has
management agreements with four medical centers (or their affiliates) for the
provision of specialized contract pharmacy services. The Company receives a
management fee for these services which is classified as other revenue.
 
    Cost of services include drug acquisition costs, pharmacy and warehouse
personnel costs, freight and other direct costs associated with the delivery of
the products and costs of clinical services provided. General and administrative
expenses include the personnel costs of the reimbursement, sales, marketing,
administrative and support staffs as well as corporate overhead and other
general expenses. Bad debts include the Company's provision for patient accounts
receivable which prove to be uncollectable after routine collection efforts have
been exhausted. The Company typically hires personnel and incurs legal,
recruiting, marketing and other expenses in anticipation of the commercial
launch of a new biotechnology drug. In certain instances, a portion of these
expenses are reimbursed to the Company by the biotechnology drug manufacturer.
The Company historically has not capitalized any of these start up expenses.
 
    Due to the increasing sensitivity to drug cost within governmental and
private payors, the Company is continuously susceptible to reimbursement and
operating margin pressures. In recent years, pharmacy benefit managers and other
private payors have aggressively attempted to discount their reimbursement rates
for the Company's products. While this aggressive discounting has resulted in
some reduced margins for the Company's services, its preferred agreements with
biotechnology manufacturers typically provide for terms which allow the Company
to compensate for much of these discounts through negotiated adjustments in
product acquisition cost. These relationships have allowed the Company to remain
price competitive while maintaining relatively stable product margins in recent
quarters.

</TABLE>
 
FISCAL YEAR ENDED JUNE 30, 1998 COMPARED TO FISCAL YEAR 1997
 
    REVENUES.  Total revenues increased from $115.2 million to $181.0 million,
or 57%, from fiscal 1997 to fiscal 1998. Approximately $25.1 million, or 38%, of
this increase was attributed to increased sales volume of
Avonex-Registered Trademark-, which was launched in May 1996. Approximately
$30.0 million, or 46%, of the increase was attributed to the increased
hemophilia revenue associated with the acquisition of HHS in June 1997 and
increased patient volume. The remaining $10.7 million, or 16%, of the revenue
increase was attributable primarily to growth in the Company's
Ceredase-Registered Trademark- and Cerezyme-Registered Trademark- drug sales and
associated service fees. The Company's equity in net income of joint ventures
increased from approximately $1.0 million to approximately $1.2 million from
fiscal 1997 to fiscal 1998.
 
    COST OF SERVICES.  Cost of services increased from $101.1 million to $154.0
million, or 52%, from fiscal 1997 to fiscal 1998. This increase was attributable
primarily to the expanded revenue volume of Avonex-Registered Trademark-,
hemophilia clotting factor and Ceredase-Registered Trademark- and
Cerezyme-Registered Trademark- along with personnel and other direct expenses
associated with this growth. As a percentage of revenues, cost of services
decreased from 87.7% to 85.1% from fiscal 1997 to fiscal 1998 primarily as a
result of the increasing revenue growth in drugs with lower product acquisition
costs as a percentage of revenue.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
from $5.9 million to $12.4 million, or 108%, from fiscal 1997 to fiscal 1998.
Approximately $4.2 million, or 66%, of this increase was associated with the
acquisition of HHS in June 1997. The remaining $2.3 million of this increase was
primarily the result of increased salaries and benefits associated with the
expansion of the Company's reimbursement, sales, marketing, administrative and
support staffs in anticipation of revenue growth and new strategic sales and
marketing efforts. As a percentage of revenues, general and administrative
expenses increased from 5.2% to
 
                                       21
<PAGE>
6.8% from fiscal 1997 to fiscal 1998 primarily as a result of the acquisition of
HHS which involves a more cost intensive service model than that of the
Company's other drug therapies.
 
    BAD DEBTS.  Bad debts increased from $3.0 million to $3.2 million from
fiscal 1997 to fiscal 1998. As a percentage of revenue, bad debt expense
decreased from 2.6% to 1.7% from fiscal 1997 to fiscal 1998 primarily as a
result of the increased percentage of the Company's revenues being reimbursed by
prescription benefit managers and other payors which reduces the Company's
exposure to the uncollectability of patient co-payments.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation expense increased from $231,000
to $430,000 from fiscal 1997 to fiscal 1998. Of this increase, $94,000 was
attributable to the assets acquired as a result of the acquisition of HHS in
June 1997. The remaining increase is a result of approximately $992,000 of
capital expenditures made in fiscal 1998 for the purchases of property and
equipment associated with the Company's revenue growth and expansion of its
leasehold facility improvements. Amortization expense increased from $1.4
million to $2.1 million from fiscal 1997 to fiscal 1998, primarily as a result
of the acquisition of HHS, which resulted in approximately $24.4 million of
goodwill and other intangible assets. Approximately $628,000 of the increase was
attributable to the amortization of those intangibles.
 
    INTEREST EXPENSE, NET.  Interest expense, net increased from $984,000 to
$3.6 million, from fiscal 1997 to fiscal 1998 primarily as a result of the
issuance of $27.5 million of long-term notes payable and $10.0 million of Senior
Subordinated Notes payable issued as part of the acquisition of HHS in June
1997. The Company generated interest income of approximately $169,000 in fiscal
1998 and $100,000 in fiscal 1997 resulting from cash management programs which
utilized the Company's increased short-term excess cash balances.
 
    INCOME TAX EXPENSE.  The Company's effective tax rate decreased from 57.3%
to 46.9% from fiscal 1997 to fiscal 1998 as a result of increased income before
income taxes while nondeductible amortization expense remained constant. The
difference between the recognized effective tax rate and the statutory tax rate
is primarily attributed to approximately $1.3 million of nondeductible
amortization expense and state income taxes.
 
PERIOD FROM INCEPTION (MAY 24, 1996) TO JUNE 30, 1996
 
    Accredo was formed on May 24, 1996, for the purpose of acquiring SHS and its
wholly owned subsidiary Nova Factor, the Company's predecessor. This acquisition
was completed on May 31, 1996. Because the financial statements for the period
from inception (May 24, 1996) to June 30, 1996 reflect only one month of the
Company's operations, a comparison of the Company's financial statements for
that period to the Company's financial statements for fiscal year 1997 would not
be meaningful.
 
PERIOD FROM JULY 1, 1995 THROUGH MAY 31, 1996 (PREDECESSOR) COMPARED TO FISCAL
  YEAR 1995 (PREDECESSOR)
 
    The results of operations for the period July 1, 1995 through May 31, 1996
(eleven-months) and for the fiscal year ended June 30, 1995 (fiscal year 1995)
are reflective of the operations of Nova Factor, the Company's predecessor. Due
primarily to the differences in the length of the reporting periods, the
comparison of the operating results may not be meaningful. In addition, the
results of operations for these periods may not be indicative of the results of
operations had the Predecessor been operated on a stand alone basis.
 
    REVENUES.  Total revenues were $74.8 million for the eleven-month period
ended May 31, 1996, and were $78.9 million for fiscal year 1995.
 
    COST OF SERVICES.  Cost of services were $65.9 million for the eleven-month
period ended May 31, 1996, and were $68.3 million for fiscal year 1995.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses were $2.8
million for the eleven-month period ended May 31, 1996, and were $2.7 million
for fiscal year 1995.
 
                                       22
<PAGE>
    BAD DEBTS.  Bad debts were $1.9 million for the eleven-month period ended
May 31, 1996, and were $1.3 million for fiscal year 1995.
 
    DEPRECIATION EXPENSE.  Depreciation expense was $104,000 for the
eleven-month period ended May 31, 1996, and was $76,000 for fiscal year 1995.
 
    CORPORATE OVERHEAD ALLOCATION.  Corporate overhead allocation was $4.2
million for the eleven-month period ended May 31, 1996, and was $1.9 million for
fiscal year 1995.
 
    INTEREST EXPENSE, NET.  Interest expense, net was $266,000 for the
eleven-month period ended May 31, 1996, and was $943,000 for fiscal year 1995.
 
    INCOME TAX EXPENSE.  The effective tax rate used to record the tax benefit
for the eleven-month period ended May 31, 1996 was approximately 27%, and was
approximately 38% for fiscal year 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of June 30, 1998 and 1997, the Company had working capital of $23.4
million and $16.9 million, respectively. The increase in working capital at June
30, 1998, as compared to June 30, 1997, resulted principally from the increase
in patient accounts receivable resulting from the Company's revenue growth. The
Company's net cash provided by operating activities was approximately $1.9
million for the fiscal year ended June 30, 1998, which was due primarily to the
timing of receivables, inventory purchases and payables resulting from the
Company's continued growth. Net cash used in investing activities was $967,000
for the fiscal year ended June 30, 1998. Such cash was used primarily for the
purchase of property and equipment.
 
    For the period from inception (May 24, 1996) through June 30, 1996, the
Company used cash in the amount of approximately $37.7 million to purchase the
outstanding stock of SHS. In fiscal year 1997, the Company used cash in the
amount of approximately $29.7 million to purchase the outstanding stock of HHS.
During fiscal 1997, the Company's cash distributions from its joint ventures in
excess of its equity in the net income from these joint ventures was $378,000.
During the fiscal year ended June 30, 1998, the Company received cash
distributions from its joint ventures of approximately $1.2 million while its
associated equity in the net income of these joint ventures increased
approximately $1.2 million.
 
    For the period from inception (May 24, 1996) to June 30, 1996, the Company
received $40.0 million from the issuance of common and preferred stock. For the
fiscal year ended June 30, 1997, the Company received approximately $27.5
million from the issuance of long-term notes payable and $10.0 million from the
issuance of the Senior Subordinated Notes which were used to refinance
approximately $7.2 million of long-term debt and to fund the acquisition of HHS.
The Company issued         shares of Common Stock to the purchasers of the
Senior Subordinated Notes. During fiscal year 1998, the Company elected to issue
additional Senior Subordinated Notes of approximately $1.0 million which
represented the accrued interest on the Senior Subordinated Notes then
outstanding. The Company also received $500,004 from the sale of         shares
of Common Stock during 1998.
 
    Historically, the Company has funded its operations and continued internal
growth through cash provided by operations. The Company anticipates its capital
expenditures for the year ending June 30, 1999 will consist primarily of
additional leasehold improvements and equipment for the continuing expansion of
the Company's leasehold to accommodate personnel necessary to manage the
Company's growth. Upon consummation of the Offering, the Company plans to retire
a portion of its long-term senior debt, redeem all outstanding shares of Series
A Preferred Stock and retire the Senior Subordinated Notes. In connection with
the retirement of debt with the Offering proceeds, the Company will incur an
extraordinary charge of approximately $2.1 million to its operations for early
extinguishment of its debt.
 
    The Company's Credit Agreement consists of a $40.0 million revolving credit
facility, which includes a subfacility for letters of credit. The Credit
Agreement contains a $20.0 million sublimit for working capital loans and
letters of credit and is subject to a borrowing base limit that is based on the
Company's cash flow. All
 
                                       23
<PAGE>
outstanding principal and interest on loans made under the Credit Agreement is
due and payable on October 31, 1999. Interest on loans under the Credit
Agreement accrues at a variable rate index, at the Company's option, based on
the prime rate or LIBOR for one, two, three or six months (as selected by the
Company), plus an applicable margin. The Company has entered into an interest
rate swap agreement with NationsBank of Tennessee, N.A. to hedge against
floating rate interest risk. The swap agreement relates to borrowings under the
Credit Agreement of up to $15.0 million and expires on October 29, 1999.
Accordingly, as of June 30, 1998, the effective interest rate on the first $15.0
million outstanding under the Credit Agreement was 8.15% per annum, and the
effective interest rate on borrowings in excess of $15.0 million under the
Credit Agreement was 7.625% per annum. The Company's obligations under the
Credit Agreement are secured by a lien on substantially all of the assets of the
Company, including a pledge of all of the common stock of each direct or
indirect wholly owned subsidiary of the Company. Each wholly owned subsidiary
has also guaranteed all of the obligations of the Company under the Credit
Agreement, which guarantee obligations are secured by a lien on substantially
all of the assets of each such subsidiary. See Note 5 of Notes to the Company's
Consolidated Financial Statements.
 
    The Credit Agreement contains operating and financial covenants, including
requirements to maintain a certain debt to equity ratio and certain leverage and
debt service coverage ratios. In addition, the Credit Agreement includes
customary affirmative and negative covenants, including covenants relating to
transactions with affiliates, use of proceeds, restrictions on subsidiaries,
limitations on indebtedness, limitations on liens, limitations on capital
expenditures, limitations on certain mergers, acquisitions and sales of assets,
limitations on investments, prohibitions on payment of dividends and stock
repurchases, and limitations on certain debt payments (including payment of
subordinated indebtedness) and other distributions. The Credit Agreement also
contains customary events of default, including certain events relating to
changes in control of the Company.
 
    While the Company anticipates its cash from operations, along with the short
term use of the Credit Agreement and the net proceeds to be received from the
Offering, will be sufficient to meet its internal operating requirements and
growth plans for at least the next 12 months, the Company expects that
additional funds may be required in the future to successfully continue its
growth beyond that 12-month period or in the event that the Company grows more
than expected within such period. The Company may be required to raise
additional funds through sales of equity or debt securities or seek additional
financing from financial institutions. There can be no assurance, however, that
financing will be available on terms that are favorable to the Company or, if
obtained, will be sufficient for the Company's needs.

QUARTERLY FLUCTUATIONS AND SEASONALITY
 
    The Company's results of operations historically have fluctuated on a
quarterly basis and can be expected to continue to be subject to quarterly
fluctuations. In particular, the Company typically increases its operating
expenses in anticipation of the launch of a new drug, and if the new drug does
not generate the levels of sales during the periods anticipated by management,
the Company's results in that and future quarters could be adversely affected.
Quarterly results can also fluctuate as a result of the timing of periodic
adjustments to prices and other terms with the Company's drug suppliers, the
accuracy of estimates of resources required for ongoing programs, the timing and
integration of acquisitions, changes in regulations related to biotechnology
companies, physician prescribing patterns, and general economic conditions, none
of which can be adequately predicted by the Company. Quarterly operating results
also fluctuate as a result of the annual renewal (on a calendar year basis) of
deductible and co-payment requirements, thereby affecting patient ordering
patterns in a manner that creates a seasonal reduction in revenue from existing
drug programs for the Company's third fiscal quarter ending March 31. The
Company believes that quarterly comparisons of its financial results may not
necessarily be meaningful and should not be relied upon as an indication of
future performance. In addition, fluctuations in quarterly results could affect
the market price of the Common Stock in a manner unrelated to the longer term
operating performance of the Company.
 
THE YEAR 2000 ISSUE
 
    INTRODUCTION.  The term "year 2000 issue" is a general term used to describe
the various problems that may result from the improper processing of dates and
date-sensitive calculations by computers and other machinery as the year 2000 is
approached and reached. These problems arise from hardware and software unable
to distinguish dates in the "2000's" from dates in the "1900's" and from other
sources such as the use of special codes and conventions in software that make
use of a date field.
 
    THE COMPANY'S STATE OF READINESS.  The Company's efforts in addressing the
year 2000 issue are focused in the following three areas: (i) implementing
procedures to determine whether the Company's software systems and hardware
platforms are year 2000 compliant; (ii) communicating with suppliers and third
party payors to determine whether there will be any interruption in their
systems that could affect the Company's ability to receive timely shipments of
inventory or payment for services as a result of the year 2000 issue; and (iii)
 
                                       25
<PAGE>
evaluating and making necessary modifications to other systems that contain
imbedded chips, such as phone systems, which process dates and date sensitive
material.
 
    The Company is in the process of obtaining written verification from vendors
to the effect that the Company's software applications and hardware platforms
acquired from such vendors will correctly manipulate dates and date-related data
as the year 2000 is approached and reached. By March 31, 1999, the Company
expects to have completed upgrades on its pharmacy management systems, including
its billing and accounts receivable systems, in order to address the year 2000
issue. Nevertheless, there can be no assurance that the software applications
and hardware platforms on which the Company's business relies will correctly
manipulate dates and date-related data as the year 2000 is approached and
reached. Such failures could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    The Company's business relies heavily upon its ability to obtain
pharmaceuticals from a limited number of biotechnology manufactures and from its
ability to obtain reimbursement from third party payors, including Medicare and
Medicaid. The Company is in the process of obtaining written verification from
each of its suppliers, and certain significant third party payors, to determine
whether there will be any interruption in the provision of pharmaceuticals or
receipt of payment resulting from the year 2000 issue. The Company expects to
complete this process by March 31, 1999. At this time HCFA has testified to a
committee of the U.S. House of Representatives that it is far behind in
remedying year 2000 problems. The failure of HCFA or any of the Company's other
significant third party payors to remedy year 2000 related problems could result
in a delay in the Company's receipt of payments for services which could have a
material adverse impact on the Company's business, financial condition and
results of operations. Furthermore, a delay in receiving pharmaceuticals from
certain key biotechnology manufacturers could hinder the Company's ability to
provide services to its customers which could have a material adverse impact on
the Company's business, financial condition and results of operations.
 
    The Company is aware that certain of its systems, such as phone systems,
facsimile machines, heating and air conditioning, security systems and other
non-data processing oriented systems may include imbedded chips which process
dates and date sensitive material. These imbedded chips are both difficult to
identify in all instances and difficult to repair; often, total replacement of
the chips is necessary. The Company intends to perform an evaluation of its
systems to determine whether the Company needs to repair or replace any chips to
avoid year 2000 problems. Failure of the Company to identify or remediate any
embedded chips (either on an individual or an aggregate basis) on which
significant business operations depend, such as phone systems, could have a
material adverse impact on the Company's business, financial condition and
results of operations.
 
    COSTS TO ADDRESS THE COMPANY'S YEAR 2000 ISSUES.  Based on current
information, the Company has budgeted $100,000 for the cost of repairing,
updating or replacing software and equipment. Because additional funds may be
required as a result of future findings, the Company is not currently able to
estimate the final aggregate cost of addressing the year 2000 issue. The Company
expects to fund the costs of addressing the year 2000 issue from cash flows
resulting from operations and does not expect such costs to have a material
effect on the financial condition of the Company or its results of operations.
 
    RISKS PRESENTED BY YEAR 2000 ISSUES.  The Company is still in the process of
evaluating potential disruptions or complications that might result from year
2000 related problems. However, at this time the Company has not identified any
specific business functions that will suffer material disruption as a result of
year 2000 related events. It is possible, however, that the Company may identify
business functions in the future that are specifically at risk of year 2000
disruption. The absence of any such determination at this point represents only
the Company's current status of evaluating potential year 2000 related problems
and facts presently known to the Company, and should not be construed to mean
that there is no risk of year 2000 related disruption. Moreover, due to the
unique and pervasive nature of the year 2000 issue, it is impracticable to
anticipate each of the wide variety of year 2000 events, particularly outside of
the Company, that might arise in a worst case scenario which might have a
material adverse impact on the Company's business, financial condition and
results of operations.
 
                                       26
<PAGE>
    THE COMPANY'S CONTINGENCY PLANS.  The Company intends to develop contingency
plans for significant business risks that might result from year 2000 related
events. Since the Company has not identified any specific business function that
will be materially at risk of significant year 2000 related disruptions, and
because a full assessment of the Company's risk from potential year 2000
failures is still in process, the Company has not yet developed detailed
contingency plans specific to year 2000 problems. Development of these
contingency plans is currently scheduled to occur before March 31, 1999 and as
otherwise appropriate.
 
IMPACT OF INFLATION
 
    Changes in prices charged by the biotechnology drug manufacturers for the
drugs dispensed by the Company, along with increasing labor costs, freight and
supply costs and other overhead expenses, affects the Company's cost of services
and general and administrative expenses. Historically, the Company has been able
to pass all, or a portion, of the effect of such increases to the biotechnology
drug manufacturers pursuant to negotiated adjustments made under its preferred
distribution agreements. As a result, changes due to inflation have not had
significant adverse effects on the Company's operations.

OVERVIEW
 
    Accredo provides specialized contract pharmacy and related services
beneficial to patients with certain costly, chronic diseases. Because of the
unique needs of these patients, biotechnology drug manufacturers have recognized
the benefits of customized treatment programs to facilitate alternate site drug
administration, ensure compliance with treatment regimens, provide reimbursement
assistance and capture valuable clinical and patient demographic information.
The Company addresses the needs of the manufacturers by providing specialized
services that facilitate product launch and patient acceptance, including timely
drug utilization and patient compliance information, patient education and
monitoring, reimbursement expertise and overnight drug delivery. The Company
believes that its ability to accelerate market penetration and increase revenues
for new biotechnology drugs makes it the partner of choice for drug
manufacturers as evidenced by its preferred relationships with Genzyme, Biogen,
Genentech and Centocor.
 
    The Company has designed its specialty services to focus primarily on
biotechnology drugs that: (i) are used on a recurring basis to treat chronic and
potentially life threatening diseases; (ii) are expensive, with an annual
therapy cost as high as $200,000 per patient; (iii) are administered through
injection; and (iv) require temperature control or other specialized handling as
part of their distribution process. Currently, the Company provides services
that address the needs of patients with the following diseases: Gaucher Disease,
a hereditary liver enzyme deficiency; hemophilia, a hereditary bleeding
disorder; Multiple Sclerosis, a debilitating disease of the central nervous
system; and growth hormone-related disorders. In addition, the Company has
recently entered into an agreement with Centocor to provide its services to
patients with Crohn's Disease, a chronic inflammatory disease affecting the
gastrointestinal tract. These diseases generally require life-long therapy,
except for growth hormone-related disorders which typically require treatment
for six to ten years.
 
INDUSTRY BACKGROUND
 
    The pace of drug discovery has accelerated in recent years due to
significant advances in disciplines such as molecular biology, genomics and
high-throughput screening. As a result, opportunities to develop therapies for
previously unmet needs are greater than ever before. Biotechnology products
represent the most expensive and rapidly growing part of the new drug pipeline,
with an estimated 240 new biotechnology products in late stage clinical trials
as of mid-1998. Unlike many traditional drugs, these products often possess
specific characteristics which make utilization and compliance increasingly
difficult. They are often composed of unstable proteins which must be taken by
injection and require timely, temperature maintained distribution, dosage
monitoring, and controlled inventory management. In addition, expert
reimbursement management is crucial as a result of the high cost and significant
support services associated with these products.
 
    As a result of increasing competitive pressure to introduce new drugs to
market quickly and the unpredictability of the approval and launch process for
new drugs, many drug manufacturers have sought to preserve often limited
internal resources by outsourcing various stages of product development. This
has included discovery research by outsourcing genomics and screening functions
and clinical development through the utilization of contract research
organizations (CROs) and site management organizations (SMOs). This trend has
also extended beyond development to product commercialization and launch through
the outsourcing of manufacturing, sales and marketing, product detailing,
pharmacy and distribution services and patient support programs.
 
    When addressing chronic diseases, the challenges facing biotechnology drug
manufacturers are often heightened by small patient populations, increased
difficulties in ensuring patient compliance and persistence with treatment
programs, the need to realize a return on investment prior to the expiration of
any patent or orphan drug status exclusivity and the onset of significant
competition. In addition, many traditional distribution channels including
wholesalers, hospitals, pharmacies and pharmacy benefit managers do not want to
maintain an inventory of expensive biotechnology products and lack the
specialized knowledge often needed to manage chronic disease patients. The
Company believes that it is well positioned to take advantage of a large drug
 
                                       28
<PAGE>
development pipeline and is at the forefront of an increasing trend toward
specialized outsourcing by the biotechnology drug industry.
 
ACCREDO STRATEGY
 
    Accredo's objective is to be the leading provider of specialized contract
pharmacy and related services. Key elements of the Company's strategy include:
 
    EXPAND NUMBER OF CHRONIC DISEASES SERVED.  The Company closely monitors
biotechnology drugs in development and seeks to increase the number of chronic
diseases for which it provides its services by developing new relationships with
additional manufacturers and leveraging its existing relationships to include
new drugs and new FDA indications for existing drugs. For example, the Company
has recently established a new preferred relationship with Centocor in which the
Company will provide its specialized services with respect to Remicade-TM- for
use in treating patients with Crohn's Disease.
 
    LEVERAGE EXPERTISE TO EXPAND SERVICE OFFERINGS.  The Company continually
seeks to develop new or complementary services that meet the specialized needs
of biotechnology drug manufacturers and the patients who use their products. The
Company believes that it is uniquely positioned to identify these needs and
develop customized solutions through its close relationships with leading drug
manufacturers. For example, the Company recently implemented a referral triage
service to provide a convenient single source for prescribing physicians and
help manufacturers increase market penetration. The Company believes that
biotechnology drug manufacturers will increasingly recognize the benefits of
outsourcing product development, launch and specialized pharmacy services as the
biotechnology market matures and competition increases.
 
    ESTABLISH ADDITIONAL RELATIONSHIPS WITH MEDICAL CENTERS.  The Company
intends to pursue additional strategic relationships with medical centers
through joint ventures and management contracts. Many of the Company's patient
populations have diseases that are discovered before or during adolescence and
require on-going care from physician specialists, who are often based at
pediatric, academic or other acute care medical centers. By establishing
strategic relationships with these centers, the Company believes it can obtain
access to a large number of patients and introduce them to the Company's
specialized services during the initial stages of their treatment program.
 
    INCREASE NUMBER OF PAYOR CONTRACTS.  The Company intends to pursue contracts
with additional payors, including managed care companies and employers, in order
to access and provide services to a greater number of patients. Because most
third party payor beneficiaries are restricted to using pharmacy providers
included in their plan's panel of providers, the Company is eligible to receive
reimbursement only for services provided to patients who are enrolled in plans
with which the Company maintains provider contracts. The Company maintains a
dedicated team of sales and marketing personnel that work exclusively on
pursuing additional payor relationships and has a variety of payor education
programs aimed at increasing awareness of the Company's specialized services
among private payors.
 
    PURSUE ACQUISITIONS OF SIMILAR OR COMPLEMENTARY BUSINESSES.  The Company
intends to pursue acquisitions that offer attractive growth opportunities and
that involve businesses that are similar to or that complement the Company's
present operations. For example, in June 1997 the Company significantly expanded
the scope of its hemophilia operations with the acquisition of HHS in Nashville,
Tennessee.
 
SERVICES
 
    The Company believes that its specialized services make it the partner of
choice for manufacturers of biotechnology drugs used in treating certain costly,
chronic diseases and the provider of choice for patients with these diseases.
These services include specialized contract pharmacy, clinical, reimbursement
and delivery services.
 
                                       29
<PAGE>
    CONTRACT PHARMACY SERVICES.  The Company offers customized services to
biotechnology drug manufacturers designed to meet specific needs that arise at
various stages in the life cycles of their products. During the pre-launch stage
of product development, the Company provides consulting services related to
strategic pricing decisions and the impact those decisions may have on private
insurance and Medicaid and Medicare reimbursement policies. The Company also
offers analyses and information to assist manufacturers in evaluating payor mix
and pricing strategies for their new drugs. The Company will test a
manufacturer's packaging to assess maintenance of product temperatures and to
determine whether the packaging system will maintain product integrity during
normal shipping conditions. In addition, the Company offers advice on ancillary
injection and infusion supplies and assists in procuring supplies and customized
packaging for infusion supply kits. The Company provides clinical protocols that
assist nurses and caregivers in learning how to safely and effectively
administer a drug, including aseptic techniques, supplies needed and infusion
time required. The Company also has extensive experience with patient assistance
programs for uninsured or underinsured patients and offers consulting services
that assist manufacturers in determining appropriate admission criteria for such
programs.
 
    Following product launch, the Company offers: (i) clinical hotlines that
allow the physician or patient caregiver to inquire about product usage, adverse
drug reactions and other clinical questions; (ii) reimbursement hotlines for
patients and health care professionals; (iii) support for manufacturers' patient
assistance programs for patients without the financial ability to otherwise
acquire needed drugs and services; (iv) replacement drug and supply programs
that replenish patients' inventory of products or supplies that become damaged;
(v) home care coordination programs that provide patient assistance in training,
the identification of home care providers and the transfer of clinical
information to all caregivers; and (vi) triage services that refer patients to
the appropriate provider based on the patients' insurance provider network.
Results of the Company's interaction with patients are coded and tracked to
compile valuable information, including side effects, drug interactions,
administration problems, supply issues, changes to new products, and reasons for
therapy discontinuation and non-compliance. The Company will also report on
adverse drug reactions, log the occurrence, and complete an initial preliminary
report of the occurrence to assist manufacturers in completing adverse event
reports in a timely manner. The Company can also create a wide variety of
additional reports that can be custom tailored to meet specific manufacturers'
needs. Examples of reports include sales by physician, sales by zip code, sales
trending, first time patient orders, Medicaid and Medicare sales, inventory
status and reasons for patient discontinuations. Due to the nature of the data
it collects, the Company has established procedures designed to ensure
compliance with laws regarding confidentiality of patient information.
 
    CLINICAL SERVICES.  At the initiation of service, the Company works with the
patient and the patient's physician to implement the prescribed plan of care.
Each patient is assigned to a team consisting of a pharmacist, a customer
service representative and a reimbursement specialist. Generally, each patient's
team members specialize only in that patient's disease and work only with payors
and providers in that patient's geographic region. In order to assist patients
with their complicated treatment program, the Company provides clinical
consultation and education regarding the patient's disease and treatment
program, helps patients set realistic expectations for their drug therapy, helps
coordinate backup care in the event of an acute episode, provides current
information on advances in technology and treatment regimens, coordinates
medication during travel and helps patients establish an inventory management
and record keeping system. Due to their limited stability, the drugs currently
handled by the Company are not mixed or reconstituted prior to shipment.
Accordingly, the Company does not mix or reconstitute any pharmaceuticals. This
makes the Company's patient education services particularly important for
patients just beginning drug therapy because they generally must learn to
reconstitute and administer products themselves. The Company maintains frequent
communication with patients to monitor and encourage compliance with the
prescribed plan of care and persistence in staying on therapy for the entire
course of treatment. The Company also helps patients understand their medication
and manage the potential side effects and adverse reactions that can occur so
that patients are less likely to discontinue therapy. In addition, the Company
assists patients and their families in coping with a variety of difficult social
and emotional challenges presented by their disease, participates in national,
state and local patient advocacy organizations, assists in the formation of
patient support groups, advocates legislation to advance specific patient
interests and publishes newsletters containing information relevant to its
patients.
 
                                       30
<PAGE>
    REIMBURSEMENT SERVICES.  By focusing on specific chronic diseases, the
Company has developed significant expertise in managing reimbursement issues
related to the patient's condition and treatment program. Due to the long
duration and high cost of therapy generally required to treat chronic disorders,
the availability of adequate health insurance is a continual concern for
chronically ill patients and their families. Generally, the Company contacts the
payor prior to each shipment to determine the patient's health plan coverage and
the portion of costs that the payor will reimburse. The Company's reimbursement
specialists review such issues as pre-certification or other prior approval
requirements, lifetime limits, pre-existing condition clauses and the
availability of special state programs. By identifying coverage limitations as
part of its initial consultation, the Company can assist the patient in planning
for alternate coverage, if necessary. From time to time, the Company negotiates
with payors to facilitate or expand coverage for the chronic diseases served by
the Company. In addition, the Company accepts assignment of benefits from
numerous payors, which substantially eliminates the claims submission process
for many patients.
 
    DELIVERY SERVICES.  The Company provides timely delivery of drugs and
ancillary supplies directly to the patient in packaging specially designed to
maintain appropriate temperatures and which typically contains all of the
supplies required for reconstitution and administration in the patient's home or
in other alternate sites. Substantially all products are shipped from the
Company's two primary pharmacy locations in Memphis and Nashville, Tennessee.
The Company also maintains satellite pharmacy locations in Dallas-Ft. Worth,
Texas and Birmingham, Alabama. The Company ships its products via FedEx and
believes that its proximity to FedEx's principal "hub" location in Memphis
provides the Company with a competitive advantage in meeting the time-sensitive
needs of its patients.
 
DISEASE MARKETS AND MANUFACTURER RELATIONSHIPS
 
    Generally, as part of the Company's preferred relationships, the
biotechnology drug manufacturers: (i) undertake promotional and marketing
efforts to generate prescriptions for their products, including direct marketing
to physicians and clinics, and then recommend the Company's services; (ii)
provide customized pricing that reflects the scope of services provided by the
Company; and (iii) review and adjust pricing periodically based on fluctuating
market conditions and changes in desired services. Currently, the Company
provides its specialty services with respect to the following diseases:
 
    GAUCHER DISEASE.  Type I Gaucher Disease is the most common form of Gaucher
Disease, affecting about 90% of all Gaucher patients. Type I Gaucher Disease is
a seriously debilitating, sometimes fatal, genetic disorder caused by a
deficiency of an important enzyme in the body called glucocerebrosidase ("GCR").
This deficiency results in the accumulation of the glucocerebroside lipid in the
cells of organs in the body. The disease is characterized by an enlarged liver
or spleen, anemia, bleeding problems, fatigue, bone and joint pain and other
orthopedic complications such as repeated fractures and bone erosion. Genzyme's
Ceredase-Registered Trademark- and Cerezyme-Registered Trademark- products are
the only FDA approved products used for treating Gaucher Disease.
 
    The Company (including former affiliates) has had a preferred relationship
with Genzyme relating to Ceredase-Registered Trademark- since its commercial
launch in 1994 and relating to Cerezyme-Registered Trademark- since its
commercial launch in 1994. Ceredase-Registered Trademark- is a modified form of
human GCR in which glycoprotein remodeling technology has been used to target
GCR to the cells where the lipid accumulation occurs.
Cerezyme-Registered Trademark- is a recombinant form of GCR which has been
remodeled in a similar manner. Ceredase-Registered Trademark- and
Cerezyme-Registered Trademark- are generally administered by intravenous
infusion. Dosing frequencies vary, but a typical dosing regimen involves
administration once every two weeks. The annual revenue to the Company during
its 1998 fiscal year from patients receiving this therapy was predominantly
within the range of $150,000 to $200,000 per patient depending on a patient's
weight, stage in the therapy cycle and severity of condition. As part of its
preferred relationship with Genzyme, the Company and Genzyme have entered into
two agreements (the "Genzyme Agreements"), pursuant to which the Company
dispenses Ceredase-Registered Trademark- and Cerezyme-Registered Trademark- in
the United States and pursuant to which the Company provides various information
and other services to Genzyme. The pricing of Ceredase-Registered Trademark- and
Cerezyme-Registered Trademark- under the Genzyme Agreements, as well as the
scope and pricing of services provided by the Company under such agreements, are
subject to periodic adjustment. The Genzyme Agreements automatically renew on an
annual basis unless either
 
                                       31
<PAGE>
party provides 90 days prior notice of non-renewal, and are terminable by either
party for any reason with 60 days prior notice. In addition, the Genzyme
Agreements provide that during the term of the agreements and for a period of
five years after termination, the Company may not sell any prescription drug for
the treatment of Gaucher Disease other than Ceredase-Registered Trademark- and
Cerezyme-Registered Trademark-. The Company does not have exclusive rights to
sell Ceredase-Registered Trademark- or Cerezyme-Registered Trademark-, and
Genzyme has reserved the right under the Genzyme Agreements to sell these
products directly or to appoint other distributors of these products.
 
    HEMOPHILIA.  Hemophilia is an inherited, genetic, lifelong bleeding disorder
caused by the absence or inactivity of an essential blood clotting protein or
"factor." Two major disease categories exist, hemophilia A, or Factor VIII
deficiency, and hemophilia B, or Factor IX deficiency. Hemophilia occurs almost
exclusively in males and severe cases are often diagnosed at birth or early
childhood. It is estimated that there are approximately 17,000 people with
hemophilia in the United States, and presently there is no known cure.
Individuals with hemophilia are susceptible to bleeding episodes which can occur
spontaneously or as a result of physical activity or trauma. While small surface
cuts can usually be treated with a pressure bandage, the most frequent
complication of hemophilia is internal bleeding into muscles and joints which
can cause arthritis and debilitating orthopedic problems. More serious
complications include internal bleeding in the head, neck, spinal cord or
internal organs which can cause death.
 
    Hemophilia is generally treated by infusing anti-hemophilic factor
concentrates intravenously when the symptoms of a bleed are detected. Products
are dispensed as freeze-dried factor concentrates which are reconstituted with
sterile water prior to use and dosage is determined by the patient's weight.
This therapy is generally administered by the patient or his or her family
members, without the assistance of a nurse, in response to bleeding episodes.
Approximately 60% of the persons with hemophilia in the United States have a
severe form of the disorder as measured by the level of factor naturally present
in the body. In general, the more severe the factor deficiency, the more
frequently the bleeding episodes may occur. On average, someone with severe
hemophilia will need to infuse factor weekly. In many individuals with severe
hemophilia, factor therapy is administered prophylactically to maintain high
enough circulating factor levels to minimize the risk of bleeding. The annual
revenue to the Company during its 1998 fiscal year from patients receiving this
therapy generally ranged from $50,000 to $100,000 per patient depending on a
patient's weight, severity of condition and the presence of complications such
as inhibitors.
 
    Today, with proper treatment, people with hemophilia can live relatively
long and healthy lives. However, in the recent past, many patients contracted
hepatitis or human immunodeficiency virus ("HIV") as a result of contaminated
plasma derivative therapies they received prior to the mid-1980's. Since then,
manufacturers of plasma-derived products have used advanced screening procedures
and viral inactivation methods. While such procedures and methods have
significantly reduced, if not eliminated, the risk of transmission of hepatitis
and HIV in current plasma-derived factor products, it is estimated that
approximately one-half of the hemophilia population who received anti-hemophilic
factor prior to the mid-1980's was exposed to HIV and is at risk of developing
acquired immune deficiency syndrome ("AIDS"). The Company offers medications
used in treating AIDS as a convenience to its hemophilia patients that have
contracted the HIV virus. In the early 1990's, recombinant clotting factor, a
biotechnological alternative to plasma-derived factor, was introduced and to
date has proved to be as effective as the plasma-derived products with virtually
no risk of viral transmission. Current utilization reflects increased use of
recombinant and monoclonal products by physicians because of the advantages of
increased purity. Issues related to the development of inhibitors, or antibodies
to the infused factor products, may influence future utilization of these
products.
 
    As one of the largest purchasers of clotting factor in the United States,
the Company has supply contracts with all major suppliers of factor in order to
maintain availability of adequate quantities of factor products and competitive
pricing. There are currently six major suppliers of FDA approved products used
for treating hemophilia. The Company purchases Kogenate-Registered Trademark-
from Bayer Corporation and Recombinate-Registered Trademark- from Baxter
Healthcare Corporation in the largest quantities, but no supplier is responsible
for a majority of the Company's hemophilia product purchases. In addition, the
Company purchases factor products from Alpha Therapeutic Corporation, Centeon
LLC, Genetics Institute, Inc. and the American Red Cross.

    MULTIPLE SCLEROSIS.  Multiple Sclerosis is a debilitating neurological
disease of the central nervous system that is characterized by episodic symptoms
followed by fixed neurologic deficits, increasing disability and physical
decline over a period of 30 to 40 years. The disease is believed to be caused by
the destruction of myelin sheaths by the body's own immune system. Myelin is the
fatty tissue that surrounds and protects the nerve fibers of the central nervous
system and facilitates the flow of nerve impulses to and from the brain. The
loss of myelin disrupts the conduction of nerve impulses, producing the symptoms
of Multiple Sclerosis including vision loss, incontinence, short-term memory
loss, fatigue, slurred speech, poor coordination, loss of balance, depression
and partial or complete paralysis. It is estimated that Multiple Sclerosis
affects between 250,000 and 350,000 people in the United States, approximately
two-thirds of whom are women. Ninety-five percent of the patients are caucasian
and the disease is more prevalent in the northern latitudes with the highest
rates in the Midwest and Northeast areas of the United States. The geography
risk for Multiple Sclerosis appears to be associated with where an individual
lived their first fifteen years of life. Disease onset typically occurs in young
adults between the ages of 20 and 40. Of the patients diagnosed with Multiple
Sclerosis in the United States, about 90% of patients initially have relapsing
Multiple Sclerosis and about half of those patients go on to develop a
progressive form of the disease. About 10% of patients exhibit a progressive
form of the disease at onset. There are currently three FDA approved products
used for treating relapsing Multiple Sclerosis: Avonex-Registered Trademark-,
which is manufactured by Biogen; Betaseron-Registered Trademark-, which is
manufactured by Chiron Corporation; and Copaxone-Registered Trademark-, which is
manufactured by Teva Pharmaceutical Industries Limited. Biogen's
Avonex-Registered Trademark- product is the only FDA approved product shown to
slow the accumulation of disability in patients with relapsing forms of Multiple
Sclerosis and, as a result, Avonex-Registered Trademark- is used by a majority
of such patients in the United States currently on drug therapy. The annual
revenue to the Company during its 1998 fiscal year from patients receiving this
therapy generally ranged from $10,000 to $11,000 per patient.
 
    The Company has had a preferred relationship with Biogen relating to
Avonex-Registered Trademark- since its commercial launch in 1996.
Avonex-Registered Trademark-, is a recombinant form of a protein produced by
fibroblast cells in response to viral infection. Avonex-Registered Trademark- is
generally administered via a single intramuscular injection once per week. As
part of its preferred relationship with Biogen, the Company and Biogen have
entered into an agreement (the "Biogen Agreement"), pursuant to which the
Company dispenses Avonex-Registered Trademark- and pursuant to which the Company
provides various services and information to Biogen. The scope of services
provided by the Company to Biogen has increased over the course of the Company's
relationship with the manufacturer as the Company has worked with Biogen to
further develop customized service offerings. The pricing of
Avonex-Registered Trademark- under the Biogen Agreement, as well as the scope
and pricing of services provided by the Company under such agreement, are
subject to periodic adjustment. The Biogen Agreement has an initial term of
three years ending May 1999 and is terminable by either party for any reason
with 90 days prior notice. In addition, the Biogen Agreement provides that as
long as the Company is the only preferred home delivery service provider
approved by Biogen (other than providers to Medicaid patients in certain
states), the Company may not without Biogen's approval sell any products that
compete with Avonex-Registered Trademark- for the treatment of Multiple
Sclerosis. The Company does not have any exclusive rights to sell
Avonex-Registered Trademark-, and Biogen has reserved the right under the Biogen
Agreement to sell Avonex-Registered Trademark- directly or to appoint other
providers of home delivery pharmacy services for Avonex-Registered Trademark-,
but such action would eliminate the Company's exclusivity obligations.
 
    GROWTH HORMONE-RELATED DISORDERS.  While growth delay in children may be
caused by a number of factors, including malnutrition, systemic illness,
psychosocial stress or endocrine deficiency, a major treatable cause of growth
delay is growth hormone deficiency. Growth hormone deficiency may result from
damage to or malfunction of the hypothalamus or pituitary gland. Growth hormone
has been used in a variety of conditions associated with short stature,
including growth retardation due to renal insufficiency and Turner's syndrome,
but the major indication for growth hormone therapy is growth hormone
deficiency. It is estimated that there are approximately 20,000 patients in the
United States who are candidates for growth hormone therapy. The use of growth
hormone to treat disorders caused by growth hormone deficiency has been
commercially available since 1985 and, therefore, the market for growth hormone
products is relatively mature. The annual revenue to the Company during its 1998
fiscal year from patients receiving this therapy generally ranged from $15,000
to $25,000 per patient depending on a patient's weight and severity of
condition. Currently, five manufacturers sell
 
                                       33
<PAGE>
nine FDA-approved growth hormone products for a variety of indications. However,
a majority of patients currently being treated with growth hormone products use
one of Genentech's growth hormone products, Protropin-Registered Trademark-,
Nutropin-Registered Trademark- or Nutropin AQ-Registered Trademark-.
 
    The Company has purchasing relationships with all five manufacturers of
growth hormone products used in the United States, including a preferred
relationship with Genentech that dates back (through former affiliates of the
Company) to the launch of Genentech's original growth hormone product,
Protropin-Registered Trademark-, in 1985. Growth hormone products are
administered by injection several times per week, and in some cases daily.
Typically, patients or family members are trained to administer the medication
at home without the presence of a nurse. As part of its preferred relationship
with Genentech, the Company and Genentech have entered into a distribution
agreement (the "Genentech Agreement"), pursuant to which the Company dispenses
Genentech's human growth hormone products, Protropin-Registered Trademark-,
Nutropin-Registered Trademark- and Nutropin AQ-Registered Trademark-, in the
United States and pursuant to which the Company provides various information and
other services to Genentech. The pricing of Protropin-Registered Trademark-,
Nutropin-Registered Trademark- and Nutropin AQ-Registered Trademark- under the
Genentech Agreement, as well as the scope and pricing of the services provided
by the Company under such agreement, are subject to periodic adjustment. The
Genentech Agreement has an initial term expiring on December 31, 1999, unless
extended by mutual agreement, and may only be terminated by either party for
cause following a 60-day right to cure or in the event of bankruptcy, insolvency
or similar events affecting the other party. In addition, the Genentech
Agreement provides that during the term of the agreement, the Company can
(subject to certain conditions) sell human growth hormone products other than
Protropin-Registered Trademark-, Nutropin-Registered Trademark- and Nutropin
AQ-Registered Trademark-. The Company does not have any exclusive rights to
distribute Protropin-Registered Trademark-, Nutropin-Registered Trademark- and
Nutropin AQ-Registered Trademark-.
 
    CROHN'S DISEASE.  Crohn's Disease is a chronic and debilitating disorder
involving inflammation of the gastrointestinal tract. Symptoms include abdominal
pain, diarrhea, fever, general fatigue and weight loss. Some patients develop
draining fistulae. Remicade-TM-, a drug developed by Centocor, has recently been
approved by the FDA for commercialization for the treatment of moderately to
severely active Crohn's Disease for the reduction of its signs and symptoms in
patients who have an inadequate response to conventional therapy. It has also
been approved as a treatment for patients with fistulizing Crohn's Disease for
reduction in the number of draining fistulae. It is believed that Remicade-TM-
reduces intestinal inflammation in patients with Crohn's Disease by binding to
and neutralizing TNF-A on the cell membrane and in the blood and by destroying
TNF-A producing cells. TNF-A is a key biologic response mediator implicated in
the inflammation process.
 
    Crohn's Disease is estimated to affect approximately 400,000 patients in the
United States, of which as many as 140,000 patients have moderate to severe
Crohn's Disease. Of those with moderate to severe Crohn's Disease, more than
40,000 suffer from fistulizing disease.
 
    The Company has recently established a preferred relationship with Centocor
relating to Remicade.-TM- Under an agreement between the Company and Centocor
(the "Centocor Agreement"), the Company will dispense Remicade-TM- and will
provide various information and other services to Centocor. The pricing of
Remicade-TM- under the Centocor Agreement, as well as the scope and pricing of
the services provided by the Company under such agreement, are subject to
periodic adjustment. The Centocor Agreement also contemplates extending the
Company's relationship with Centocor to an additional indication for
Remicade-TM- if the additional indication receives all required approvals. This
additional indication is currently in Phase III clinical trials. The Centocor
Agreement has an initial term of three years ending August 2001, with a renewal
provision, and it is terminable by either party for any reason with 90 days
prior notice. In addition, the Centocor Agreement provides that during the term
of the agreement and for a period of 90 days after termination of the agreement,
the Company may not sell any other company's treatment for inflammatory bowel
disease or any other indication for which the FDA has approved the use of
Remicade-TM-. The Company does not have any exclusive rights to sell
Remicade-TM-, and Centocor has reserved the right under the Centocor Agreement
to sell Remicade-TM- directly or to appoint distributors or other providers of
pharmacy services for Remicade-TM-. Centocor's decision to appoint other
providers of pharmacy services would eliminate the Company's exclusivity
obligations.

BUSINESS DEVELOPMENT
 
    The Company has 23 full time sales and marketing personnel who sell the
Company's therapies and services to physicians, patients and private payors. The
Company also creates special direct marketing programs to potential referral
sources who specialize in care and support of patients with chronic disorders.
The Company's sales and support personnel also work closely with each of the
referral sources with the goal of addressing the clinical and reimbursement
needs of their patients. The Company assists in clinical studies, professional
training seminars, distribution of patient support material, development of
patient support groups, and other programs designed to assist patients, payors,
manufacturers and physicians in enhancing the quality of care and quality of
life for patients and their families.
 
    The Company continually seeks to obtain contracts with additional payors,
including managed care companies and employers, in order to access and provide
services for a greater number of patients. Because most third party payor
beneficiaries are restricted to using pharmacy providers included in their
payor's provider panel, the Company is eligible to receive reimbursement only
for services provided to patients covered by payors with whom the Company
maintains provider contracts. The Company maintains a dedicated team of sales
and marketing personnel that work exclusively on pursuing additional payor
relationships and has a variety of payor education programs aimed at increasing
awareness of the Company's specialized services among private payors.
 
    In addition, the Company has a full time director of business development
whose responsibilities include tracking biotechnology drugs in development,
determining whether these drugs meet the Company's service criteria and are a
strategic fit for the Company, introducing the Company's services to the
manufacturers of these drugs and assisting in the development of customized
services for these manufacturers. There were an estimated 240 biotechnology
drugs in late stage development as of mid-1998. The Company targets
biotechnology drug manufacturers that have a need to outsource specialized
contract pharmacy and related services to an experienced provider of such
services rather than develop the capabilities internally.
 
SUPPLIERS
 
    Substantially all of the biotechnology drugs sold by the Company, other than
clotting factor products, are available only from single sources: Genzyme, with
respect to Ceredase-Registered Trademark- and Cerezyme-Registered Trademark-;
Biogen, with respect to Avonex-Registered Trademark-; Genentech, with respect to
Protropin-Registered Trademark-, Nutropin-Registered Trademark- and Nutropin
AQ-Registered Trademark-; and Centocor, with respect to Remicade-TM-. Although
there are four other manufacturers of FDA approved growth hormone products,
Genentech's products collectively enjoy a market share that exceeds the
aggregate of all other individual manufacturers of growth hormone products.
Accordingly, in the event that one or more of its current suppliers of products
(other than hemophilia products) were to cease selling products to the Company,
the Company's business, financial condition and results of operations would be
materially and adversely affected. Approximately 14% and 23% of the Company's
total revenues in the fiscal years ended June 30, 1997 and 1998, respectively,
were derived from sales of Avonex-Registered Trademark- and related services. In
addition, approximately 64% and 46% of the Company's total revenues in the
fiscal years ended June 30, 1997 and 1998, respectively, were derived from sales
of Ceredase-Registered Trademark- and Cerezyme-Registered Trademark- and related
services. The Company has supply contracts with all five major suppliers of
clotting factor in the United States, and no supplier is responsible for a
majority of the Company's hemophilia product purchases.
 
    The Company's agreements with its key suppliers (including Genzyme, Biogen,
Genentech and Centocor) generally may be canceled by either party, without
cause, upon between 60 and 90 days prior notice. Furthermore, the Company and
its suppliers periodically adjust the acquisition cost and other terms for the
drugs and related supplies covered by such contracts. In addition, the Company's
agreements with its suppliers generally provide that during the term of the
agreements (and in certain instances for as much as five years after termination
of the agreements), the Company may not distribute any competing products. The
Company does not have any exclusive rights to distribute its products, and its
suppliers have generally reserved the right under their agreements with the
Company to distribute their products directly or to appoint other distributors
of their
 
                                       35
<PAGE>
products. See "Risk Factors--Dependence on Relationships with Limited Number of
Biotechnology Drug Manufacturers" and "Business--Disease Markets and
Manufacturer Relationships."
 
STRATEGIC RELATIONSHIPS WITH MEDICAL CENTERS
 
    Many of the patients served by the Company have diseases that are discovered
before or during adolescence and require on-going care from specialist
physicians, who are often based at pediatric, academic or other acute care
medical centers. In order for the Company to obtain access to additional
patients and introduce them to the Company's specialized services during the
initial stages of their treatment program, the Company seeks to establish
strategic relationships, including joint ventures and management contracts, with
such medical centers.
 
    The Company currently has joint ventures with four medical centers (or their
affiliates): Zale Lipshy
University Hospital located in Dallas, Texas; Alternative Care Systems, Inc.
located in Dallas, Texas; Cook Childrens Medical Center located in Ft. Worth,
Texas; and Children's Memorial Hospital located in Chicago, Illinois. In the
typical joint venture arrangement, the Company and a medical center (or its
affiliate) form a joint venture entity that then enters into a management
agreement with the Company to obtain specialized contract pharmacy services.
Under the terms of the joint venture agreement, the Company manages the sales,
marketing and provision of specialty pharmacy services in exchange for a monthly
management fee and the reimbursement of certain expenses. Generally, the Company
and the medical center share in the profits and losses of the joint venture
entity in proportion to their respective capital contributions. The agreements
generally have initial terms of between one and five years and contain certain
restrictive covenants and rights of first refusal.
 
    In addition to joint venture relationships, the Company has entered into
management agreements with medical centers (or their affiliates) to provide
specialized contract pharmacy services. The Company currently has contract
management relationships with four medical centers (or their affiliates):
Egleston Children's Hospital at Emory University located in Atlanta, Georgia;
duPont Hospital for Children located in Wilmington, Delaware; Children's
National Medical Center located in Washington D.C.; and Childrens Hospital of
Los Angeles located in Los Angeles, California. Pursuant to these management
agreements, the Company provides goods and services used in the medical center's
specialized pharmacy business, including drugs and related supplies, patient
education, clinical consultation and certain reimbursement services. While the
payment terms under such management agreements vary, the Company is generally
reimbursed for its costs and is paid a monthly management fee from the sale of
those products and services. These agreements usually have terms of between one
and five years and are terminable by either party, with or without cause, with
between one and twelve months prior notice. See "Risk Factors--Dependence on
Medical Center Relationships."
 
PAYORS
 
    The following are the approximate percentages of the Company's gross patient
service revenue attributable to various payor categories for the fiscal year
ended June 30, 1998:
 
<TABLE>
<S>                                                                     <C>
Private payors (including self pay)(1)................................         80%
Medicaid and other state programs.....................................         17%
Medicare and other federal programs...................................          3%
                                                                               --

                                                                               --
</TABLE>
 
- ------------------------------
 
(1) Includes sales to private physician practices, whose ultimate payor is
    typically Medicare, which accounted for approximately 7% of gross patient
    service revenue for fiscal 1998.
 
    The Company typically agrees to furnish drugs and services to substantially
all patients recommended to the Company by its referral sources. The Company
believes this approach is important to maintain the confidence, support, and
loyalty of referral sources. The Company acts on behalf of the patients it
serves to assist them in obtaining reimbursement from third-party payors,
including managed care companies. Generally, the Company contacts third-party
payors before the commencement of services or delivery of product in order to
 
                                       36
<PAGE>
determine the patient's coverage and the percentage of costs that the payor will
cover. The Company's reimbursement staff reviews issues such as lifetime limits,
pre-existing condition clauses, the availability of special state programs, and
other reimbursement-related matters. The Company often will negotiate with
third-party payors on the patient's behalf to obtain or extend coverage. The
Company typically obtains assignment of benefits from patients that enable it to
file claims for its services and be paid directly for the covered amounts of its
charges. Due to the high cost of the products distributed by the Company and the
complexity of payor systems, claims often cannot be submitted electronically,
which increases labor costs associated with obtaining reimbursement. As with
most health care providers, the Company can experience lengthly collection
periods as a result of third party payment systems and, consequently, management
of accounts receivable through patient registration, billing, collection and
reinbursement procedures is critical to the Company.
 
    The primary trend in the United States health care industry is toward cost
containment. The increasing prevalence of managed care, centralized purchasing
decisions, consolidation among and integration of health care providers and
competition for patients has and continues to affect pricing, purchasing and
usage patterns in health care. Decisions regarding the use of a particular drug
treatment are increasingly influenced by large private payors, including managed
care organizations, pharmacy benefit managers, group purchasing organizations,
regional integrated delivery systems and similar organizations and are becoming
more economically focused, with decisions taking into account product cost and
whether a product reduces the cost of treatment. Efforts by payors to eliminate,
contain or reduce costs through coverage exclusions, lower reimbursement rates,
greater claims scrutiny, closed provider panels, restrictions on required
formularies, claim delays or denials and other similar measures could adversely
affect the Company's revenues, profitability and cash flow. Certain payors set
lifetime limits on the amount reimbursable to patients for medical costs.
Certain of the Company's patients may reach these limits because of the high
cost of their medical treatment and associated pharmaceutical regimens. To date,
the Company has not had significant experience with patients reaching lifetime
limits. Certain payors may attempt to further control costs by selecting certain
firms to be their exclusive providers of pharmaceutical or other medical product
benefits. If any such arrangements were with the Company's competitors, the
Company would be unable to be reimbursed for purchases made by such patients.
 
    The Company derives a significant portion of its revenue from governmental
programs such as Medicare and Medicaid. Such programs are highly regulated and
subject to frequent and substantial changes and cost containment measures. In
recent years, changes in these programs have limited and reduced reimbursement
to providers and Congress recently enacted the Balanced Budget Act of 1997
(which establishes a plan to balance the federal budget by fiscal year 2002)
that includes significant additional reductions in spending levels for these
programs. This legislation also replaced and relaxed the federal Medicaid
payment standard thereby increasing state discretion over administration of
Medicaid programs. Furthermore, federal and state proposals are pending that
would impose further limitations on governmental payments and that would
increase patient co-payments and deductibles. Additionally, a number of states
are considering legislation designed to reduce their Medicaid expenditures and
provide universal coverage and additional care for certain populations,
including proposals to impose additional taxes on providers to help finance or
expand such programs. Any of these changes could result in significant
reductions in payment levels for drugs handled and services provided by the
Company, which would have a material adverse affect on the Company's business,
financial condition and results of operations. In addition, the Company may be
required to maintain a licensed pharmacy in certain states in order to qualify
for reimbursement under state administered reimbursement plans. See "Risk
Factors--Dependence on Payors and Reimbursement Risks."
 
    Certain of the medical centers with which the Company has a joint venture or
management relationship have hemophilia treatment centers ("HTC") that are
eligible to purchase factor from manufacturers at a discount pursuant to a
provision of the Public Health Service Act as enacted by the Veteran's Health
Care Act of 1992 ("PHS Pricing"). Manufacturers that sell outpatient drugs to
eligible entities sign an agreement with DHHS under which they agree to not
charge a price for covered outpatient drugs in excess of a statutorily set
amount. The Company does not directly own or operate an HTC that is eligible for
PHS Pricing, which may place it at a competitive disadvantage as a provider of
factor, except in the limited circumstances where its affiliated medical
 
                                       37
<PAGE>
centers are eligible for PHS Pricing. Under DHHS contract pharmacy guidelines,
an eligible HTC may obtain factor at PHS Pricing, and dispense it to patients of
the HTC through a contract pharmacy. However, eligible centers which fail to
comply with the contract pharmacy guidelines, or divert PHS Pricing factor to
non-patients of the HTC in violation of DHHS guidelines, may incur civil
penalties, or liability to drug manufacturers for the amount of discount
provided.
 
COMPETITION
 
    The specialty pharmacy services industry is highly competitive and is
experiencing both horizontal and vertical consolidation. The industry is
fragmented, with many public and private companies focusing on different product
or customer niches. Some of the Company's current and potential competitors
include specialty pharmacy divisions of national wholesale drug distributors;
specialty pharmacy distributors, such as Caremark Therapeutic Services (a
subsidiary of MedPartners, Inc.) and Olsten Corporation; pharmacy benefit
management companies; hospital-based pharmacies; retail pharmacies; home
infusion therapy companies; certain manufacturers that sell their products both
to distributors and directly to users, including clinics and physician offices;
and hospital-based comprehensive hemophilia care centers and other alternate
site health care providers. Some of the Company's competitors have greater
financial, technical, marketing and managerial resources than the Company.
 
    While competition is often based primarily on price and quality of care and
service, it can also be affected by the ability to develop and maintain
relationships with patients and referral sources, depth of product line,
technical support systems, specific patient requirements and reputation. There
can be no assurance that competitive pressures will not have a material adverse
effect on the Company's business, financial condition and results of operations.
 
    Through federal legislation such as the Social Security Act, as amended, the
Veterans Health Care Act of 1992, and the Public Health Services Act, and the
rules and regulations thereunder, manufacturers of certain types of outpatient
drugs, including clotting factor, are required to provide price discounts for
such drugs to various types of federally funded hemophilia treatment centers,
which is a competitive advantage to such providers not available to the Company.
 
COMPLIANCE PROGRAM
 
    The Company adopted a new corporate compliance program, entitled "Code of
Ethics and Business Conduct," in February 1998 (the "Compliance Program"). Upon
accepting a job with the Company, employees receive a written copy of the
Compliance Program and are asked to read the document prior to their first day
of employment. A training session is conducted during new employee orientation
and all employees are required to sign a written acknowledgment that he or she
has read and understands the Compliance Program and will adhere to the standards
set forth therein. The Company has a corporate compliance officer and a
compliance committee with representation from each operating subsidiary. The
compliance officer is responsible for administering the program, which includes
training, internal audits and reviews, and responding to reported issues with
the assistance of the compliance committee. Employees are encouraged to ask
questions or reveal potential compliance issues to either their supervisor or
their compliance committee member or via a toll free hotline number. These calls
can be made anonymously, if so desired. Employees also receive corporate
compliance training twice a year with respect to potential compliance issues.
Issues that are reported to the committee will normally be handled at the
committee level unless the compliance officer believes that the Company's Board
of Directors should be involved. At least once a year, the corporate compliance
officer will meet with or submit a written report to the Company's Board of
Directors. While there is not a standing compliance committee of the Board of
Directors, an outside director, Kenneth R. Masterson, has been designated as a
liaison from whom the compliance officer may seek advice.

<PAGE>
GOVERNMENT REGULATION
 
    The conduct of marketing, selling and purchasing drugs and medical supplies
by and among manufacturers, distributors, health care providers and patients is
extensively regulated and periodically scrutinized by state and federal
governments for compliance with laws and regulations regarding, among other
things, inducements for referrals, prohibited financial relationships with
physicians, joint venture and management arrangements, product discounts,
incentives to patients and professional licensure. This regulatory framework is
complex and the laws are very broad in scope, subject to differing
interpretations and lack substantive court decisions addressing many
arrangements under which the Company has and expects to conduct its business.
Because civil and criminal sanctions may be imposed for violations of these
laws, compliance is a significant operational requirement for the Company.
Because of the nature of this regulatory framework, there can be no assurance
that all of the Company's business practices would be construed to comply with
these laws in all respects, and any violation or alleged violation of these laws
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
    The Company is unable to predict the future course of federal, state and
local regulation, legislation or enforcement, and changes in this complex
regulatory framework or in the interpretation of these laws, rules and
regulations could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    LICENSURE AND REGISTRATION.  In general, the Company's pharmacy operations
are regulated by the statutes and regulations of Tennessee, where it is licensed
as a retail pharmacy and wholesale distributor of pharmaceuticals, as well as
the states of of Alabama, and Texas, where it operates satellite retail
pharmacies. In addition, the Company currently delivers prescription products
from its licensed pharmacies to patients in other states in which the Company
does not operate a pharmacy. Many of these states have laws or regulations
requiring out-of-state pharmacies to be licensed as a condition to the delivery
of prescription products to patients in such states. The Company believes that
it is in substantial compliance with such laws as are applicable.
 
    Various federal and state pharmacy associations and some boards of pharmacy
have attempted to promote laws or regulations directed at restricting the
activities of out-of-state pharmacies, thereby benefiting local pharmacies with
which the Company competes from time to time. In addition, a number of states
have laws or regulations which, if successfully enforced, would effectively
limit some of the financial incentives available to third-party payors that
offer managed care prescription drug programs. To the extent such laws or
regulations are found to be applicable to the Company, there is no assurance the
Company could comply, and noncompliance could adversely affect the Company's
pharmacy service operations.
 
    The federal and state controlled substances laws and regulations govern
manufacturers, distributors and dispensers of controlled substances. Any person
who manufactures, distributes, or dispenses controlled substances must obtain a
registration from the United States Attorney General and, where required, from
the appropriate state agency. A separate registration is required at each
principal place of business where the applicant manufactures, distributes, or
dispenses controlled substances. The laws and regulations also specify label and
packaging requirements for manufacturers and distributors and record-keeping and
reporting requirements for all registrants. Although the Company maintains
federal and applicable state regulations under these laws, it handles small
amount of inventory that are subject to controlled substances laws.
 
    PROFESSIONAL PRACTICE.  State laws prohibit the practice of pharmacy without
a license. Accordingly, the Company's pharmacists are all licensed in Tennessee,
and other states where required. The Company monitors the professional aspects
of their practice. However, to the extent that the Company's employees assist
patients and providers in helping patients comply with prescribed treatment
programs, such activities could be deemed by a state to be the practice of
medicine, nursing, or outside the scope of permitted pharmacy practice.
 
    PHARMACY COUNSELING LAW.  Federal support of state Medicaid programs for
covered outpatient drugs is conditioned on the state having a drug use review
("DUR") program. The DUR program must consist of prospective drug review,
retrospective drug use review, the application of predetermined standards, and
an
 
                                       39
<PAGE>
educational program. The purpose of the DUR program is to improve the quality of
pharmaceutical care by ensuring that prescriptions are appropriate and medically
necessary, and that they are not likely to result in adverse medical effects. As
part of the program, the state must develop standards containing the minimum
specified requirements for the counseling by pharmacists of patients or their
caregivers. The standards must address special situations where the patient or
the patient's representative is not readily available to receive an offer to
counsel, such as prescriptions delivered through the mail. The Company believes
that its pharmacists monitor these requirements and provide the requisite
counseling in the ordinary course of their activities.
 
    FEDERAL MAIL ORDER.  In addition to state regulations of pharmacies and
pharmacists, federal statutes and regulations establish standards for the
labeling, packaging, repackaging, advertising and adulteration of prescription
drugs and the dispensing of "controlled" substances and prescription drugs. To
the extent that the Company were to use the federal postal service, Federal
Trade Commission and United States Postal Service regulations require mail order
sellers to engage in truthful advertising, to stock a reasonable supply of
drugs, to fill mail orders within thirty days and, if that is impossible, to
inform the consumer of his or her right to a refund. The Company believes that
it is in substantial compliance with the above requirements.
 
    THE PRESCRIPTION DRUG MARKETING ACT.  The federal Prescription Drug
Marketing Act ("PDMA") provides that certain drugs and devices, generally those
requiring a prescription by a physician, are exempted from the federal labeling
and packing requirements, upon the condition that such drugs are not adulterated
or misbranded. The PMDA also generally prohibits the selling, purchasing, or
trading of any drug sample, which is not intended to be sold or intended to
promote the sale of the drug. The PMDA imposes certain documentation and record
keeping requirements, as well as proper drug storage and maintenance
requirements, in connection with the distribution of drug samples. In those
instances where the PMDA applies to drugs or services provided by the Company,
the Company believes that it complies with the PMDA through its ordinary course
of documentation, record keeping and storage procedures.
 
    ANTI-KICKBACK AND SELF-REFERRAL.  As a health care company, the Company is
subject to various federal laws that regulate the relationship between providers
of health care services and referral sources such as physicians and hospitals.
Under the Medicare, Medicaid and other programs of government payment and
reimbursement of health-related costs, the federal and state governments enforce
a federal statute that prohibits the offer, payment, solicitation or receipt of
any remuneration, directly or indirectly, overtly or covertly, in cash or in
kind to induce or in exchange for (i) the referral of patients covered by the
programs, or (ii) the leasing, purchasing, ordering or arranging for or
recommending the lease, purchase or order of any item, good, facility or service
covered by the programs (the "Anti-Kickback Law"). Penalties include criminal
fines, civil monetary penalties, and imprisonment, and the exclusion of anyone,
including an individual or an entity who has committed any of the prohibited
acts, from participation in the Medicare and Medicaid programs whether such
individual or entity participates in such governmental programs directly or
indirectly. If applied to the Company, any of its personnel, or any significant
customer or business partner of the Company, such sanctions could have a
material adverse effect on the Company's business, financial condition and
results of operations. Additionally, the sanctioning or exclusion of a
manufacturer or a recipient of the Company's services from those programs, for
activities unrelated to those of the Company, could also have a material adverse
effect on the Company's business, financial condition and results of operations.
 
    In addition, numerous states have existing or proposed laws that prohibit
financial arrangements among health care providers. These state laws are not
necessarily limited to items or services for which payment is made by Medicare
or Medicaid. Violations of these laws include civil and criminal penalties, as
well as the suspension or termination of a provider's ability to continue to
provide services in the state. Federal and state court decisions interpreting
these federal and state statutes are limited, but some courts have construed the
statutes to apply if "one purpose" of remuneration is to induce referrals or
other conduct within the proscriptions of the statute.
 
    In an effort to curb health care fraud, Congress included several anti-fraud
measures in the Health Insurance Portability and Accountability Act of 1996
("HIPAA"). HIPAA, among other things, amends existing
 
                                       40
<PAGE>
crimes and criminal penalties for Medicare fraud and enacts new federal health
care fraud crimes. HIPAA also expands the federal Anti-Kickback Law to apply to
all federal health care programs, which is any plan or program that provides
health benefits through insurance funded by the federal government. Under HIPAA,
the Secretary of the Department of Health and Human Services ("the Secretary")
may exclude from the Medicare program any individual who has a direct or
indirect ownership or control interest in a health care entity that has been
convicted of a health care fraud crime or that has been excluded from the
Medicare program, if the individual knew or should have known of the action
constituting the basis for the conviction or exclusion of the entity. HIPAA
directs the Secretary to establish a program to collect information on health
care fraud and abuse to encourage individuals to report information concerning
fraud and abuse against the Medicare program and provides for payment of a
portion of amounts collected to such individuals. HIPAA mandates the
establishment of a Fraud and Abuse Program, among other programs, to control
fraud and abuse with respect to health plans and to conduct investigations,
audits, evaluations, and inspections relating to the delivery of and payment for
health care in the United States.
 
    HIPAA prohibits any person or entity from knowingly and willfully committing
a federal health care offense relating to a health care benefit program. Under
HIPAA, a "health care benefit program" broadly includes "any public or private
plan or contract, affecting commerce, under which any medical benefit, item, or
service is provided to any individual." Among the "federal health care offenses"
prohibited by HIPAA are health care fraud and making false statements relative
to health care matters. Any person or entity that knowingly and willfully
defrauds or attempts to defraud a health care benefit program or obtains by
means of false or fraudulent pretenses, representations, or promises, any of the
money or property of any health care benefit program in connection with the
delivery of health care services is subject to a fine and/or imprisonment. In
addition, HIPAA provides that any person or entity that knowingly and willfully
falsifies or conceals or covers up a material fact or makes any materially false
or fraudulent statements in connection with the delivery of or payment of health
care services by a health care benefit plan is subject to a fine and/or
imprisonment. These provisions of HIPAA represent the criminalization of
situations which previously would have been handled civilly through the
administrative processes of repayments of overpayments, offsets, and fines.
 
    The Anti-Kickback Law and similar state statutes are broad in scope, subject
to frequent modification and differing interpretations. In an attempt to clarify
which arrangements are not subject to prosecution under the Anti-Kickback Law,
the Department of Health and Human Services ("DHHS") adopted a set of "safe
harbor" regulations and continues to publish clarifications to such safe
harbors. Arrangements that comply with all the requirements of all applicable
safe harbors are deemed not to violate the Anti-Kickback Law. The Company has
several business arrangements such as, without limitation, joint venture and
management arrangements with medical centers, service arrangements with
physicians and product pricing arrangements with suppliers, do not satisfy all
of the requirements necessary to fall within the safe harbors, and there is not
safe harbor protection for each and every Company arrangement. Due to the
breadth and complexity of these laws and regulations, and the absence in many
instances of court decisions addressing arrangements by which the Company has
conducted and expects to conduct its business, it is possible that some of the
Company's practices could be challenged. Although failure of a transaction or
arrangement to fit within a specific safe harbor provision does not necessarily
mean that the structure of the transaction is illegal or that prosecution under
the Anti-Kickback Law will be pursued, there can be no assurance that the
Company's practices will not be challenged, or that the Company will not be
subject to sanctions or be required to alter or discontinue certain of its
practices, any of which could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    OIG FRAUD ALERTS.  The Office of Inspector General ("OIG") has issued "Fraud
Alerts" identifying certain arrangements and practices which it believes may
implicate the federal fraud and abuse laws. The OIG has issued a Fraud Alert
providing its views on certain joint venture and contractual arrangements
between health care providers. The OIG has issued a Fraud Alert concerning
prescription drug marketing practices that could potentially violate federal
fraud and abuse laws. Pharmaceutical marketing activities may implicate the
federal fraud and abuse laws because drugs are often paid for by Medicare and
the Medicaid program. According to the
 
                                       41
<PAGE>
Fraud Alert, examples of practices that may implicate the fraud and abuse laws
include arrangements under which remuneration is made to pharmacists to
recommend the use of a particular pharmaceutical product. In addition, a number
of states have recently undertaken enforcement actions against pharmaceutical
manufacturers involving pharmaceutical marketing programs, including programs
containing incentives for pharmacists to dispense one particular product rather
than another. These enforcement actions arise under state consumer protection
laws which generally prohibit false advertising, deceptive trade practices and
the like. Further, a number of the states involved in these enforcement actions
have requested that the FDA exercise greater regulatory oversight in the area of
pharmaceutical promotional activities by pharmacists. It is not possible to
determine whether the FDA will act in this regard or what effect, if any, FDA
involvement would have on the Company's operations.
 
    THE STARK LAW.  The Company and any physician (or the physician's immediate
family members) with whom the Company may have business dealings are also
subject to the Ethics in Patient Referrals Act of 1989, commonly called the
"Stark Law." Unless excepted, the Stark Law prohibits physicians from making a
referral for the rendering of certain health-related items or services if such
practitioner or his or her family member has a financial relationship with the
entity receiving the referral. Correspondingly, such entity cannot bill for a
service or item provided pursuant to a prohibited referral. The prohibitions of
the Stark Law apply to the products and services provided by the Company. Among
other sanctions, a civil monetary penalty may be levied for each product or
service provided pursuant to a prohibited referral upon both the person making
the referral and the provider rendering the service. Such persons or entities
are also subject to exclusion from Medicare and Medicaid. The prohibitions of
the Stark Law apply to the Company's products and services. Due to the breadth
and complexity of the Stark Law and the absence of court decisions construing
such law, it is possible that some of the Company's practices could be
challenged and there can be no assurance that the Company will not be subject to
sanctions or be required to alter or discontinue certain of its practices, any
of which could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    BENEFICIARY INDUCEMENT.  HIPAA created new civil monetary penalties for
individuals and entities that offer remuneration or other inducements to the
beneficiaries of federal health care programs, such as Medicare, Medicaid and
CHAMPUS, which the provider knows or should know will influence the
beneficiaries' decision to seek specific governmentally reimbursable items or
services or to choose a particular provider to provide those items or medical
services. HIPAA provides an exception to this prohibition by excluding items
provided to promote the delivery of preventive care. Under the statutory
exemption, it would not be considered impermissible remuneration for a provider
to give certain types of incentives to a beneficiary to encourage the
beneficiary to receive preventive care. The statutory exception would apply
where "such care is provided or directly supervised by the medical provider that
has provided the incentive."
 
    The OIG has issued proposed regulations concerning the HIPAA prohibition
against inducements to beneficiaries (the "Proposed Regulations"). In contrast
to the statute, the OIG has taken the position that the statutory exception for
incentives to promote preventive care does not include the "direct rendering of
preventive medical care." The Preamble of the Proposed Regulations provides
examples of the type of preventive care incentives the OIG would consider
permissible under this statutory exemption: (i) transportation to and from
preventive care services; (ii) car seats, formula and other items for those
participating in prenatal or postnatal classes; (iii) tee shirts, videos and
water bottles for those participating in post-cardiac care fitness programs. The
OIG has indicated that items and services related to general health promotion
such as health club memberships, vitamins, nutritional supplements and the like
would not be permissible incentives under the statutory exception. The OIG has
also stated that permissible incentives would not include cash or cash
equivalents. As the OIG noted in the Preamble, the committee report on these
provisions had stated that the provision of items and services of nominal value
was permissible, offering as examples, "refreshments, medical literature,
complimentary local transportation services, or participation in free health
fairs." The OIG has interpreted this statement restrictively to mean that the
aggregate value of such services is nominal and that the provision of even
nominally priced incentives on a frequent basis would be impermissible. The
Company from time to time provides certain items at no charge to its patients in
connection with their drug therapies. Although the
 
                                       42
<PAGE>
Company believes these items fall within the scope of the statutory preventive
care exception, or are otherwise of nominal value, there can be no assurance
regarding the scope of any final regulations, or that the Company will not be
challenged on its practices and suffer applicable sanctions or be required to
alter or discontinue its "no charge" practices, any of which could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
    THE FALSE CLAIMS ACT.  The Company is also subject to federal and state
laws, including the federal False Claim Act, prohibiting an individual or entity
from knowingly and willfully presenting claims for payment (by Medicare,
Medicaid, or other third party payors) that contain false or fraudulent
information. These laws also provide for both criminal and civil penalties.
Furthermore, providers found to have submitted claims which they knew or should
have known were false, fraudulent, or for items or services that were not
provided as claimed, may be excluded from Medicare and Medicaid participation,
required to repay previously collected amounts, and subject to substantial civil
monetary penalties.
 
    GOVERNMENT INVESTIGATIONS.  There is increasing scrutiny by law enforcement
authorities, the OIG, the courts, and Congress of arrangements between health
care providers and potential referral sources to ensure that the arrangements
are not designed as a mechanism to exchange remuneration for patient care
referrals and opportunities. Investigators have demonstrated a willingness to
look behind the formalities of a business transaction to determine the
underlying purpose of payments between health care providers and potential
referral sources. Enforcement actions have increased, as evidenced by recent
highly publicized enforcement investigations. Although, to its knowledge, the
Company is not currently the subject of any investigation, there can be no
assurance that the Company will not be the subject of investigations or
inquiries in the future nor that any such investigation would not have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
    In addition to investigations and enforcement actions initiated by
governmental agencies, health care companies may also be the subject of qui tam
actions brought under the False Claims Act by private individuals on behalf of
the government. Furthermore, actions under the False Claims Act, commonly known
as "whistleblower" lawsuits are generally filed under seal to allow the
government adequate time to investigate and determine whether it will intervene
in the action, and defendant health care providers are often without knowledge
of such actions until the government has completed its investigation and the
seal is lifted.
 
    CONFIDENTIALITY.  Various federal and state laws establish minimum standards
for the maintenance of medical records and protect the confidentiality of
patient medical information. In the course of its business, the Company
maintains medical records for each patient to whom it dispenses drugs. As a
result, it is subject to one or more of these medical record and patient
confidentiality laws. In addition, the Company may become subject to new rules
recently mandated by the HIPAA, and proposed by the Health Care Financing
Administration ("HCFA") to ensure the integrity and confidentiality of patient
data by creating mandatory security standards for entities which maintain or
transmit health information electronically. Unauthorized disclosure of
confidential patient information, or other failure to comply with any applicable
laws and regulations regarding the maintenance of patient records and the
confidentiality of medical information, could have a material adverse effect on
the Company's business, financial condition and results of operation.
 
    BALANCED BUDGET ACT.  Each state has its own Medicaid program that is funded
jointly by the state and Federal government. Federal law governs how each state
manages its Medicaid program, but there is wide latitude for states to customize
Medicaid programs to fit the needs and resources to their citizens. As a result,
each state Medicaid plan has its own payment formula and recipient eligibility
criteria. In recent years, changes in Medicare and Medicaid programs have
resulted in limitations on, and reduced levels of, payment and reimbursement for
a substantial portion of health care goods and services. Congress recently
enacted the Balanced Budget Act of 1997, which establishes a plan to balance the
federal budget by fiscal year 2002, and includes significant additional
reductions in spending levels for the Medicare and Medicaid programs.
 
                                       43
<PAGE>
    The Medicare, Medicaid, CHAMPUS and other governmental programs are subject
to statutory and regulatory changes, administrative rulings, interpretations and
determinations, requirements for utilization review and new governmental funding
restrictions, all of which may materially increase or decrease program payments
as well a affect the cost of providing services and the timing of payments. The
final determination of amounts earned under the programs often requires many
years, because of audits by the program representatives, providers' rights of
appeal and the application of numerous technical provisions. The Company
believes adequate provision has been made for such adjustments. Until final
adjustment, however, significant issues remain unresolved and payments received
could be recouped.
 
    REFORM.  Political, economic and regulatory influences are subjecting the
health care industry in the United States to fundamental change. A variety of
new approaches have been proposed, including mandated basic health care
benefits, controls on health care spending through limitations on the growth of
private health insurance premiums and Medicare and Medicaid spending, and the
creation of large purchasing groups. In addition, some of the states in which
the Company operates have adopted or are considering various health care reform
proposals. The Company anticipates that Congress and state legislatures will
continue to review and assess alternative health care delivery systems and
payment methods and that public debate of these issues will likely continue in
the future. Because of uncertainty regarding the ultimate features of reform
initiatives and their enactment and implementation, the Company cannot predict
which, if any, of such reform proposals will be adopted, when they may be
adopted, or what impact they may have on the Company.
 
FACILITIES
 
    The Company's corporate headquarters is located in Memphis, Tennessee and
its primary pharmacy locations are in Memphis and Nashville, Tennessee. In
addition, the Company has a satellite pharmacy location in the Birmingham,
Alabama area and two satellite pharmacy locations in the Dallas/Ft. Worth, Texas
area.
 
    MEMPHIS, TENNESSEE.  The Company currently leases an aggregate of
approximately 42,000 square feet of space in an office/warehouse business park
in Memphis, Tennessee pursuant to two lease agreements that expire in 2003, each
with an option to extend the lease term for one additional five year period.
 
    NASHVILLE, TENNESSEE.  The Company currently leases approximately 24,000
square feet of space in Nashville, Tennessee pursuant to a lease agreement that
expires in October 1999, with an option to extend the lease term for one
additional five year period.
 
    BIRMINGHAM, ALABAMA.  The Company currently leases approximately 2,400
square feet of space in the Birmingham, Alabama area pursuant to a lease
agreement that expires in February 2000.
 
    DALLAS/FORT WORTH, TEXAS.  The Company currently leases an aggregate of
approximately 1,800 square feet of space in two locations in the Dallas/Ft.
Worth, Texas area pursuant to two lease agreements that expire in May 1999, each
with an option to extend the lease term for one additional three year period.
 
EMPLOYEES
 
    The Company had 242 full-time and 29 part-time employees at June 30, 1998.
None of the Company's employees are represented by a labor union, and management
considers its relations with its employees to be good.
 
LIABILITY INSURANCE
 
    Providing health care services and products entails an inherent risk of
liability. In recent years, participants in the health care industry have become
subject to an increasing number of lawsuits, many of which involve large claims
and significant defense costs. The Company may from time to time be subject to
such suits as a result of the nature of its business. The Company maintains
general liability insurance, including professional and product liability, in an
amount deemed adequate by management. There can be no assurance, however, that
 
                                       44
<PAGE>
claims in excess of, or beyond the scope of, the Company's insurance coverage
will not arise. In addition, the Company's insurance policies must be renewed
annually. Although the Company has not experienced difficulty in obtaining
insurance coverage in the past, there can be no assurance that it will be able
to do so in the future on acceptable terms or at all.
 
LEGAL PROCEEDINGS
 
    The Company is involved in various lawsuits and claims arising in the normal
course of business. In the opinion of Company management, although outcomes of
these lawsuits and claims are uncertain, in the aggregate they should not have a
material adverse effect on the Company's business, financial condition or
results of operations.

(1) These values were determined using the Black-Scholes methodology and the
    assumptions described in Note 10 to the Company's Consolidated Financial
    Statements included in this Prospectus.
 
(2) Mr. Callahan was granted an incentive stock option to purchase      shares
    of Common Stock (divided into      Tranche A option shares and      Tranche
    B option shares) and an incentive stock option to purchase      shares of
    Common Stock (divided into     Tranche A option shares and     Tranche B
    option shares) on September 3, 1997 and February 9, 1998, respectively. The
    exercise price per share of each option was equal to the fair market value
    of the Common Stock on the respective dates of grant, as determined by the
    Board of Directors. Pursuant to each option, the option shares subject to
    Tranche A will vest at an annual rate of 25%, and the option shares subject
    to Tranche B will vest in 2002 (or at an annual rate of 25% in the event the
    Company meets certain performance goals based upon target earning levels).
    The options will vest immediately upon certain changes in control of the
    Company. The term of each option expires ten years from the date of grant
    (or earlier, in the event the optionee ceases to be employed by the Company
    or any subsidiary or parent thereof).

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    Messrs. Welsh and Paul, who presently serve as members of the Compensation
Committee of the Board of Directors, served on the Compensation Committee during
the fiscal year ended June 30, 1998. Neither Messrs. Welsh or Paul, nor any
executive officer of the Company, serves as a member of a board of directors or
compensation committee of any entity that has one or more executive officers
serving as a member of the Company's Board of Directors.
 
EMPLOYMENT AGREEMENTS
 
    The Company has entered into employment agreements with Messrs. Stevens,
Grow and Kimbrough as of May 31, 1996, and with Mr. Bell as of July 10, 1998.
HHS, a wholly owned subsidiary of the Company, entered into an employment
agreement with Mr. Callahan as of June 5, 1997. The terms of such employment
agreements expire on May 31, 1999 (with respect to Messrs. Stevens, Grow and
Kimbrough), June 1, 2000 (with respect to Mr. Callahan), and June 30, 2001 (with
respect to Mr. Bell), although each employment agreement is subject to automatic
one-year renewals. The Company may terminate the employment agreements at any
time. Each employment agreement provides that in the event the Company
terminates the executive's employment without "cause" (as defined therein) and
other than by reason of his death or disability, or in the event the executive
terminates his or her employment for "good reason" (as defined therein), the
executive shall continue to receive his or her salary as a severance payment for
a certain period of time (one year, with respect to Messrs. Stevens, Grow,
Kimbrough and Bell, and 18 months, with respect to Mr. Callahan). In addition,
upon such termination, Messrs. Stevens, Grow, Kimbrough and Bell would be
entitled to continue to participate in the Company's benefit plans for a period
of one year (or until the commencement of other full-time employment, whichever
is earlier).
 
    The employment agreements entitle Messrs. Stevens, Grow, Kimbrough, Bell and
Callahan to annual base salaries presently set at $252,000, $170,000, $163,500,
$168,000 and $163,500, respectively. Each employment agreement also provides for
the payment of an annual bonus of up to 50% of salary with respect to Messrs.
Stevens, Grow, Kimbrough and Callahan and up to 40% of salary with respect to
Mr. Bell, based upon the extent to which the Company achieves certain
performance goals based upon target earning levels established by the Board.
Each of the employment agreements entitles the executive to all benefits
provided by the Company for its senior executives. In addition, the Company has
agreed to maintain $500,000 in term life insurance for each of Messrs. Stevens,
Grow, Kimbrough and Bell, payable to their respective named beneficiaries.
 
    Each of the employment agreements prohibits the executive's disclosure and
use of confidential information and restricts, for certain periods of time
following termination of employment (12 months, with respect to Messrs. Stevens,
Grow, Kimbrough and Bell, and 36 months, with respect to Mr. Callahan), his
solicitation of certain employees of the Company, conduct of certain business
with the Company's five largest suppliers, or competition with the Company.
 
LONG-TERM INCENTIVE PLAN
 
    The Accredo Health, Incorporated 1998 Long-Term Incentive Plan (the
"Incentive Plan"), was adopted by the Board of Directors of the Company on
     , and was approved by the Company's stockholders on      . A summary of the
Incentive Plan is set forth below. The summary is qualified in its entirety by
reference to the full text of the Incentive Plan, a copy of which is included as
an exhibit to the Registration Statement of which this Prospectus is a part.
 
    The purpose of the Incentive Plan is to promote the success, and enhance the
value, of the Company by linking the personal interests of employees, officers,
consultants and directors to those of the stockholders, and by providing such
persons with an incentive for outstanding performance. As of      , there were
approximately      persons eligible to participate in the Incentive Plan.
 
                                       50
<PAGE>
    The Incentive Plan authorizes the granting of awards ("Awards") to
employees, officers, consultants and directors of the Company or its
subsidiaries in the following forms: (i) options to purchase shares of Common
Stock ("Options"), which may be incentive stock options that meet the
requirements of Section 422 of the Internal Revenue Code of 1986, as amended
(the "Code") ("ISOs") or non-qualified stock options ("NQSOs"), (ii) stock
appreciation rights ("SARs"); (iii) performance units ("Performance Units");
(iv) restricted stock ("Restricted Stock"); (v) dividend equivalent rights; and
(vi) other stock-based awards. Subject to adjustment as provided in the
Incentive Plan, the aggregate number of shares of Common Stock reserved and
available for Awards or which may be used to provide a basis of measurement for
or to determine the value of an Award (such as with a SAR or Performance Share)
is      . The maximum number of shares of Common Stock with respect to one or
more Options and/or SARs that may be granted during any one calendar year under
the Incentive Plan to any one participant is      . The maximum fair market
value of any Awards (other than Options and SARs) that may be received by a
participant (less any consideration paid by the participant for such Award)
during any one calendar year under the Incentive Plan is $        .
 
    The Incentive Plan is administered by the Compensation Committee, which has
the power, authority and discretion to designate participants; determine the
type or types of Awards to be granted to each participant and the terms and
conditions thereof; establish, adopt or revise any rules and regulations as it
may deem necessary or advisable to administer the Incentive Plan; and make all
other decisions and determinations that may be required under, or as it deems
necessary or advisable to administer, the Incentive Plan. The Board or the
Compensation Committee may, at any time and from time to time, terminate, amend
or modify the Incentive Plan without stockholder approval. No termination,
amendment, or modification of the Incentive Plan may adversely affect any Award
previously granted under the Incentive Plan, without the consent of the
participant.
 
    Upon the participant's death or disability during his or her employment or
his or her service as a director, all outstanding Options, SARs, and other
Awards in the nature of rights that may be exercised will become fully vested
and exercisable and all restrictions on outstanding Awards will lapse. In
addition, in the event of a Change in Control of the Company (as defined in the
Incentive Plan), all outstanding Options, SARs, and other Awards in the nature
of rights that may be exercised will become fully vested and exercisable and all
restrictions on all outstanding Awards will lapse. Unexercised or restricted
Awards generally will not be assignable or transferable by a participant other
than by will or the laws of descent and distribution or, except in the case of
an ISO, pursuant to a qualifying domestic relations order.
 
    Pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended
(the "Code"), the Company may not deduct compensation in excess of $1.0 million
paid to the Chief Executive Officer and the four next most highly compensated
executive officers of the Company. The Incentive Plan is designed to comply with
Code Section 162(m) so that the grant of Options and SARs under the Incentive
Plan, and other Awards, such as Performance Shares, that are conditioned on the
performance goals described in the Incentive Plan, will be excluded from the
calculation of annual compensation for purposes of Code Section 162(m) and will
be fully deductible by the Company.
 
STOCK OPTION AND RESTRICTED STOCK PURCHASE PLAN
 
    The Nova Holdings, Inc. and its Subsidiaries Stock Option and Restricted
Stock Purchase Plan, as amended and restated (the "Option Plan"), became
effective as of May 31, 1996, the date of its original adoption by the Board of
Directors of the Company. The amendment and restatement of the Option Plan was
approved by the Company's stockholders on June 30, 1997. A summary of the Plan
is set forth below. The summary is qualified in its entirety by reference to the
full text of the Plan, a copy of which is included as an exhibit to the
Registration Statement of which this Prospectus is a part.
 
    The Option Plan authorizes the granting of options to purchase shares of
Common Stock, which may be ISOs or NQSOs, and other related awards, to
employees, officers, and directors of the Company or its subsidiaries. Subject
to adjustment as provided in the Option Plan, the aggregate number of shares of
Common
 
                                       51
<PAGE>
Stock for which Options or awards may be granted under the Option Plan is      .
As of July 31, 1998, there were approximately 30 persons eligible to participate
in the Plan.
 
    The Option Plan is administered by the Compensation Committee, which has the
power, authority and discretion to designate participants, determine the type or
types of awards to be granted to each participant and the terms and conditions
thereof, and establish any other terms, restrictions and conditions applicable
to any option or award not inconsistent with the provisions of the Option Plan.
The Board or the Compensation Committee may, at any time and from time to time,
terminate, amend or modify the Option Plan without stockholder approval;
provided that stockholder approval shall be required in the case of an amendment
to increase the aggregate number of shares issuable subject to the Option Plan,
to decrease the minimum exercise price in respect of ISOs, or to change the
class of employees eligible to receive ISOs under the Option Plan. No
termination, amendment, or modification of the Option Plan may adversely affect
any option or award previously granted under the Option Plan, without the
consent of the participant.
 
EMPLOYEE STOCK PURCHASE PLAN
 
    The Accredo Health, Incorporated 1998 Employee Stock Purchase Plan (the
"ESPP") was adopted by the Board of Directors of the Company on      , and was
approved by the Company's stockholders on      . The purpose of the ESPP, which
is intended to qualify as an employee stock purchase plan under Section 423 of
the Code, is to enhance the proprietary interest among the employees of the
Company and its participating subsidiaries through ownership of Common Stock of
the Company. A summary of the ESPP is set forth below. The summary is qualified
in its entirety by reference to the full text of the ESPP, a copy of which is
included as an exhibit to the Registration Statement of which this Prospectus is
a part.
 
    Pursuant to the ESPP, eligible employees make contributions, through payroll
deductions, to a plan account during a six-month "offering period." The offering
periods commence and end on or about January 1 to June 30 and July 1 to December
31 of each year. On the first business day of each offering period, the Company
will grant to each participant in the ESPP an option to purchase, on the last
day of such offering period, a maximum of      shares of Common Stock. No option
will be granted to a participant if such option, when combined with all other
options granted under all of the Code Section 423 employee stock purchase plans
of the Company, its parents and its subsidiary corporations, would permit such
participant to purchase shares of Common Stock of the Company having a fair
market value in excess of $25,000 per year.
 
    The participant will be entitled to exercise such option to the extent of
the participant's accumulated payroll deductions on the last day of such
offering period; provided, however, that if the participant's accumulated
payroll deductions on the last day of the offering period would enable the
participant to purchase more than      shares, the excess of the amount of the
accumulated payroll deductions over the aggregate purchase price of the shares
will be refunded to the participant, without interest. The option price for each
offering period will be the lesser of (i) 85% of the fair market value of the
Common Stock on the first business day of the offering period, or (ii) 85% of
the fair market value of the Common Stock on the last business day of the
offering period. Employees may authorize payroll deductions in amounts not less
than one percent (1%) but not more than ten percent (10%) of their respective
total compensation, including base pay or salary and any bonuses or commissions.
 
    Each employee of the Company and each employee of any participating
subsidiary is eligible to participate in the ESPP, provided such employee: (i)
is regularly scheduled to work at least 20 hours each week and at least five
months in the calendar year, and (ii) immediately after the grant of an option
to him or her under the ESPP would own less than five percent of the total
combined voting power or value of all classes of stock of the Company or any of
its subsidiaries. As of              , there were approximately   employees
eligible to participate in the ESPP.
 
    Shares subject to the ESPP may be authorized but unissued shares or shares
that were once issued and subsequently reacquired by the Company. The total
number of shares of Common Stock for which options may be granted under the ESPP
is      shares, subject to adjustment in accordance with the ESPP.
 
                                       52
<PAGE>
    The ESPP will be administered by the Compensation Committee or the Board of
Directors, which will have authority to interpret and administer the ESPP. The
ESPP may be terminated at any time by the Board, but such termination will not
affect options then outstanding. The ESPP will terminate in any case when all or
substantially all of the unissued shares of stock reserved for the purposes of
the ESPP have been purchased. If at any time shares of stock reserved for the
ESPP remain available for purchase but not in sufficient number to satisfy all
then unfilled purchase requirements, the available shares will be apportioned
among participants in proportion to their options and the ESPP will terminate.
Upon termination, all payroll deductions not used to purchase stock will be
refunded. The Committee or the Board may from time to time amend the ESPP
provided that, without the approval of the stockholders, no amendment may (i)
materially affect the eligibility requirements or the definition of "Employer,"
(ii) increase the number of shares of Common Stock subject to any options issued
to participants, or (iii) materially increase the benefits to participants under
the Plan.
 
    An employee's rights under the ESPP will terminate when he or she ceases to
be an employee for any reason, and the cash balance in his or her contribution
account will be distributed to such employee (or his or her designated
beneficiary). An employee's rights under the ESPP may not be transferred other
than by will or the laws of descent and distribution. Any option granted under
the ESPP to an employee may be exercised, during the employee's lifetime, only
by the employee.
 
401(K) PLAN
 
    The Company sponsors a defined contribution plan (the "401(k) Plan") for
eligible employees of the Company under Section 401(k) of the Code. Participants
may contribute up to 18% of their annual compensation to the 401(k) Plan,
subject to certain limitations. All contributions made by participants are fully
vested and are not subject to forfeiture. The Company makes matching
contributions to the 401(k) Plan on behalf of each eligible participant based
upon the participant's total years of service with the Company. The Company
matches 25% of "eligible contributions" (as defined in the 401(k) Plan) made by
participants with less than five years of service, and 50% of eligible
contributions made by participants with five or more years of service.

                              CERTAIN TRANSACTIONS
 
INITIAL FORMATION, CAPITALIZATION AND ACQUISITION OF SHS.
 
    In May 1996, the Company (formerly known as Nova Holdings, Inc.) was formed
for the purpose of acquiring all of the outstanding equity securities of SHS,
then a subsidiary of Le Bonheur. In connection with the initial capitalization
of the Company, Welsh Carson purchased an aggregate of      shares of the
Company's Common Stock for $14,917,602 and an aggregate of 248,624 shares of
Series A Preferred Stock for $24,862,400. Additional investors purchased a total
of      shares of the Company's Common Stock for $82,398 and 1,376 shares of
Series A Preferred Stock for $137,600. In connection with the Recapitalization,
Welsh Carson will exchange      shares of Common Stock for      shares of
Non-Voting Common Stock. All outstanding shares of Series A Preferred Stock will
be redeemed by the Company with a portion of the net proceeds from the Offering.
 
    On May 31, 1996, the Company acquired all of the outstanding Class A Common
Stock and Class B Common Stock of SHS (the "SHS Common Stock"). Prior to the
Company's purchase of the SHS Common Stock, SHS spun-off its three subsidiaries
other than Nova Factor and repurchased certain shares of SHS Common Stock held
by persons other than Le Bonheur. In addition, Messrs. Grow, Kimbrough and
Stevens (in addition to certain other holders of SHS Common Stock) exchanged
their shares of SHS Common Stock for      ,      and      shares of the
Company's Common Stock, respectively, and 978 shares, 611 shares and 3,056
shares of Series A Preferred Stock, respectively.
 
REGISTRATION RIGHTS AGREEMENT
 
    In connection with the formation of the Company in May 1996, Welsh Carson
entered into a Registration Rights Agreement with the Company (the "Registration
Rights Agreement"). The Registration Rights Agreement provides for demand
registration rights that may be exercised on up to two occasions by the holders
of Restricted Stock (as defined therein, which definition includes substantially
all shares of Common Stock outstanding prior to the Offering) constituting at
least a majority of the total Restricted Stock outstanding at the time of
exercise. The Registration Rights Agreement also provides unlimited demand
registration rights to holders of Restricted Stock for registrations on Form
S-3, so long as the reasonably anticipated aggregate price to the public of such
offering is at least $1.0 million; provided, however, that such demand
registrations may not be exercised more than once every 180 days. No
registration effected pursuant to these unlimited demand registration rights on
Form S-3 will be counted toward the limit of two demand registration rights
referred to above.
 
    The Registration Rights Agreement also provides that, subject to certain
limitations including the discretion of the managing underwriter in an
underwritten offering, holders of Restricted Stock may request inclusion of
their shares in a registration of securities initiated by the Company. The
Company is required to pay all costs of any registration pursuant to the
Registration Rights Agreement, subject to certain limitations provided in the
agreement. All of the parties to the Registration Rights Agreement have waived
any right to participate in this Offering.
 
    All shares of Common Stock owned by the executive offices and directors of
the Company are shares of Restricted Stock as such term is defined in the
Registration Rights Agreement and are, therefore, subject to the above described
registration rights.
 
ACQUISITION OF HHS
 
    In June 1997, the Company purchased all of the outstanding shares of common
stock of HHS for an aggregate purchase price of approximately $29,996,000.
Dianne R. Griffith, one of the two stockholders of HHS and the mother of Mr.
Callahan, has received approximately $20,302,000 in connection with the sale of
her HHS stock to the Company. In addition, approximately $3,395,000 of
additional consideration to Ms. Griffith is currently being held in escrow
pending settlement of certain liabilities. Upon such settlement, any remaining
 
                                       54
<PAGE>
amounts in escrow will be paid to Ms. Griffith. Ms. Griffith also entered into a
three month consulting agreement with the Company pursuant to which she provided
certain consulting services to the Company in exchange for a total of $21,875
plus a percentage of the base salary of Sara Meyers, a former employee of HHS,
for each of those three months.
 
    Ms. Griffith leases approximately 24,000 square feet of office space located
in Nashville, Tennessee to HHS pursuant to a lease that expires on October 31,
1999. The Company is obligated under the lease to make annual rent payments to
Ms. Griffith in the amount of $302,277.
 
    Also in connection with the acquisition of HHS, the Company entered into an
employment agreement and a stock option agreement with Mr. Callahan. See
"Management--Executive Compensation" and "--Employment Agreements." Mr.
Callahan's employment agreement permits him to terminate his employment for
"good reason", including if he is willing to serve and he is not elected to the
Board of Directors of the Company while WCAS VII owns a majority of the
outstanding Common Stock and the Company has not consummated an initial public
offering. Pursuant to a letter dated June 3, 1997, WCAS VII agreed to vote its
shares of Common Stock to elect Mr. Callahan to the Board of Directors of the
Company, and Mr. Callahan was elected to the Board on June 30, 1997. Also, on
October 1, 1997, Mr. Callahan purchased      shares of Common Stock for a total
purchase price of $250,002 and was granted registration rights covering those
shares with the same terms and conditions as those granted to Welsh Carson in
the Registration Rights Agreement.
 
10% SENIOR SUBORDINATED NOTES DUE JANUARY 1, 2004
 
    On June 4, 1997, Welsh Carson purchased $10.0 million of the Company's
Senior Subordinated Notes. The Senior Subordinated Notes bear interest at 10%
and are due and payable in full on June 1, 2004, with interest payable thereon
quarterly in arrears on the first day of March, June, September and December of
each year commencing on September 1, 1997. At the option of the Company, the
amount of interest due and payable through June 1, 1999 may be added to the
unpaid principal balance of the Senior Subordinated Notes.
 
    Upon the Company's prior written notice to the holders of the Senior
Subordinated Notes, the Company may prepay all or any portion of the Senior
Subordinated Notes. The Company is required to make certain mandatory
prepayments of the Senior Subordinated Notes in full if at any time while the
Senior Subordinated Notes are outstanding: (i) the Company merges or
consolidates with or into another entity (subject to certain exceptions); (ii)
the Company sells or otherwise disposes of substantially all of its assets to a
third-party; or (iii) the Company consummates a public offering of equity
securities pursuant to an effective registration statement under the Securities
Act of 1933. The Company intends to prepay in full the entire principal balance
of the Senior Subordinated Notes and all accrued interest thereon with a portion
of the net proceeds of this Offering. See "Use of Proceeds."
 
    In connection with the issuance of the Senior Subordinated Notes, the
Company also issued to purchasers of the Senior Subordinated Notes      shares
of Common Stock for each $25 principal amount of Senior Subordinated Notes
purchased, for a total of      shares of Common Stock.
 
COMMON STOCK PURCHASES BY AFFILIATES
 
    In connection with the appointment of Mr. Melkus to the Company's Board of
Directors, his daughter, Lauren Melkus, acquired      shares of Common Stock for
$250,002 on October 27, 1997. In addition, Mr. Masterson, upon his appointment
to the Company's Board of Directors, acquired      shares of Common Stock for
$204,000 on July 24, 1998 pursuant to a subscription agreement entered into by
Mr. Masterson in April 1998. Both Ms. Melkus and Mr. Masterson were granted
registration rights covering those shares with the same terms and conditions as
those granted to Welsh Carson in the Registration Rights Agreement. See "--
Registration Rights Agreement."

    prior to the Offering and      shares of Common Stock (including Non-Voting
    Common Stock) outstanding after the Offering. Pursuant to the rules of the
    Commission, shares of Common Stock which a person has the right to acquire
    within 60 days pursuant to the exercise of stock options are deemed to be
    outstanding for the purpose of computing the percentage ownership of such
    person but are not deemed outstanding for the purpose of computing
    percentage ownership of any other person. Accordingly, the totals for the
    following persons include the following shares represented by options
    exercisable within 60 days of August 31, 1998: Mr. Stevens,      shares; Mr.
    Kimbrough,      shares; Mr. Callahan,      shares; Mr. Grow,      shares;

                          DESCRIPTION OF CAPITAL STOCK
 
    The following summary is a description of certain provisions of the
Company's Amended and Restated Certificate of Incorporation (the "Certification
of Incorporation"). Such summary does not purport to be complete and is subject
to, and is qualified in its entirety by, all of the provisions of the
Certificate of Incorporation, a copy of which is included as an exhibit to the
Registration Statement of which this Prospectus is a part.
 
    Upon completion of the Offering, the Company's authorized capital stock will
consist of   ,000,000 shares of Common Stock, $0.01 par value per share,
shares of Non-Voting Common Stock, $0.01 par value per share ("Non-Voting Common
Stock"), and   ,000,000 shares of preferred stock, $1.00 par value per share
("Preferred Stock"), Currently, there are outstanding      shares of Common
Stock and 255,361 shares of Series A Preferred Stock. All outstanding shares of
Series A Preferred Stock will be redeemed by the Company using a portion of the
net proceeds from the Offering. Upon completion of the Offering and, the Company
will have outstanding      shares of Common Stock (including      shares of
Non-Voting Common Stock) and no shares of Preferred Stock.
 
COMMON STOCK
 
    The holders of Common Stock are entitled to one vote per share on all
matters to be voted on by stockholders and are not entitled to cumulative voting
in the election of directors. The holders of Common Stock are entitled to share
ratably in dividends, if any, as may be declared from time to time by the Board
of Directors in its discretion out of funds legally available therefor. The
Company currently anticipates that all of its earnings will be retained to
finance the growth and development of its business and, therefore, does not
anticipate that any cash dividends will be declared on the Common Stock in the
foreseeable future. See "Dividend Policy". The holders of Common Stock are
entitled to share ratably in any assets remaining after satisfaction of all
prior claims upon liquidation of the Company. The Certificate of Incorporation
gives holders of Common Stock no preemptive or other subscription or conversion
rights, and there are no redemption provisions with respect to such shares. All
outstanding shares of Common Stock are, and the shares offered hereby will be,
when issued and paid for, fully paid and nonassessable. The rights, preferences,
and privileges of holders of Common Stock are subject to, and may be adversely
affected by, the rights of holders of shares of any series of Preferred Stock
which the Company may designate and issue in the future.
 
NON-VOTING COMMON STOCK
 
    The shares of Non-Voting Common Stock to be issued to WCAS VII pursuant to
the Recapitilization will be fully paid and nonassessable. Subject to the prior
rights of the holders of any Preferred Stock, and on a pro rata basis with the
holders of Common Stock, the holders of outstanding shares of Non-Voting Common
Stock are entitled to receive dividends out of assets legally available therefor
at such time and in such amounts as the Board of Directors may from time to time
determine. The shares of Non-Voting Common Stock are convertible into Common
Stock at any time provided that WCAS VII will not own 50% or more of the Common
Stock after such conversion. In the event WCAS VII sells any Non-Voting Common
Stock to third parties, such shares shall automatically convert to Common Stock.
The holders of Non-Voting Common Stock have no preemptive or subscription rights
to purchase any securities of the Company. Upon liquidation, dissolution or
winding up of the Company, and on a pro rata basis with the holders of Common
Stock, the holders of Non-Voting Common Stock are entitled to receive pro rata
the assets of the Company that are legally available for distribution after
payment of all debts and other liabilities and subject to the prior rights of
any holders of Preferred Stock then outstanding. Holders of outstanding shares
of Non-Voting Common Stock will not be entitled to vote such shares on any
matter submitted to a vote of stockholders.
 
PREFERRED STOCK
 
    Subject to conditions specified in the Certificate of Incorporation, the
Delaware General Corporation Law ("DGCL") and other applicable law, the Board of
Directors has the authority to issue undesignated Preferred
 
                                       57
<PAGE>
Stock in one or more class or series and to determine the dividend rights,
dividend rate, conversion rights, voting rights, redemption rights and terms,
liquidation preferences, sinking fund provisions, number of shares constituting
any class or series, and designations of such class or series without any
further vote or action by the stockholders of the Company. The Company has no
present intention to issue any shares of Preferred Stock.
 
    One of the effects of undesignated Preferred Stock is to enable the Board of
Directors to render more difficult or to discourage an attempt to obtain control
of the Company by means of a tender offer, proxy contest, merger or otherwise,
and thereby to protect the continuity of the Company's management. For example,
the Company could issue a series of Preferred Stock having characteristics that
would make a takeover prohibitively expensive. The issuance of shares of the
Preferred Stock pursuant to the Board of Directors' authority described above
may adversely affect the rights of the holders of Common Stock. For example,
Preferred Stock issued by the Company may rank senior to the Common Stock as to
dividend rights, liquidation preference or both, may have full or unlimited
voting rights and may be convertible into shares of Common Stock. Accordingly,
the issuance of shares of Preferred Stock may discourage bids for the Common
Stock or may otherwise adversely affect the market price of the Common Stock.
 
SPECIAL PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS AND DELAWARE LAW
 
    Certain provisions of the Certificate of Incorporation and the Company's
Amended and Restated Bylaws (the "Bylaws") may be deemed to have an
anti-takeover effect or may delay, defer or prevent a tender offer or takeover
attempt that a stockholder might consider in such stockholder's best interest,
including those attempts that might result in a premium over the market price
for the shares held by such stockholder.
 
    DELAWARE ANTI-TAKEOVER LAW.  Section 203 of the DGCL ("Section 203") applies
to the Company and generally provides that a person who, together with
affiliates and associates owns, or within three years did own, 15% or more of
the outstanding voting stock of a corporation subject to the statute (an
"Interested Stockholder"), but less than 85% of such stock, may not engage in
certain business combinations with the corporation for a period of three years
after the date on which the person became an Interested Stockholder unless (i)
prior to such date, the corporation's board of directors approved either the
business combination or the transaction in which the stockholder became an
Interested Stockholder, (ii) the Interested Stockholder acquired 85% or more of
the outstanding voting stock of the corporation in the same transaction that
makes such person an Interested Stockholder (excluding shares owned by persons
who are both officers and directors of the corporation, and shares held by
certain employee stock ownership plans), or (iii) subsequent to such date, the
business combination is approved by the corporation's board of directors and
authorized at a stockholders' meeting by a vote of at least two-thirds of the
corporation's outstanding voting stock not owned by the Interested Stockholder.
Section 203 defines the term "business combination" to encompass a wide variety
of transactions with or caused by an Interested Stockholder, including mergers,
asset sales, and other transactions in which the Interested Stockholder receives
or could receive a benefit on other than a pro rata basis with other
stockholders.
 
    The Company's stockholders, by adopting an amendment to the Certificate of
Incorporation, may elect not to be governed by Section 203, which election would
be effective 12 months after such adoption. Neither the Certificate of
Incorporation nor the Bylaws presently exclude the Company from the restrictions
imposed by Section 203, and the restrictions imposed by Section 203 apply to the
Company. The provisions of Section 203 could delay or frustrate a change in
control of the Company, deny stockholders the receipt of a premium on their
Common Stock and have a depressing effect on the market price of the Common
Stock. The provisions also could discourage, impede or prevent a merger, tender
offer or proxy contest, even if such event would be favorable to the interests
of stockholders.
 
    CLASSIFIED BOARD OF DIRECTORS.  The Certificate of Incorporation provides
for the Board of Directors to be divided into three classes of directors serving
staggered three-year terms. A director may be removed from office prior to the
expiration of his or her term only "for cause," so any person acquiring control
of the Company would need three annual meetings to replace all of the members of
the Board of Directors. The classified board provision of the Certificate of
Incorporation could have the effect of making the removal of incumbent directors
 
                                       58
<PAGE>
more time-consuming and difficult, and, therefore discouraging a third party
from making a tender offer or otherwise attempting to obtain control of the
Company, even though such an attempt might be beneficial to the Company and its
stockholders. Thus, the classified board provision could increase the likelihood
that incumbent directors will retain their positions. The Company believes that
a classified Board of Directors will help to assure the continuity and stability
of the Board of Directors and of the business strategies and policies of the
Company as determined by the Board of Directors. See "Management."
 
    NUMBER OF DIRECTORS; REMOVAL; FILLING VACANCIES.  The Certificate of
Incorporation and Bylaws provide that the number of directors will be fixed from
time to time with the consent of two-thirds of the Board of Directors. Moreover,
the Certificate of Incorporation provides that directors may only be removed
with cause by the affirmative vote of the holders of at least a majority of the
outstanding shares of capital stock of the Company then entitled to vote at an
election of directors. This provision prevents stockholders from removing any
incumbent director without cause and allows two-thirds of the incumbent
directors to add additional directors without approval of stockholders until the
next annual meeting of stockholders at which directors of that class are
elected.
 
    ADVANCE NOTICE OF NOMINATIONS AND STOCKHOLDER PROPOSALS.  The Bylaws contain
a provision requiring at least 60 but no more than 90 days' advance notice by a
stockholder of a proposal or director nomination that such stockholder desires
to present at any annual or special meeting of stockholders, which would prevent
a stockholder from making a proposal or a director nomination at a stockholder
meeting without the Company having advance notice of the proposal or director
nomination. This provision could make a change in control more difficult by
providing the directors of the Company with more time to prepare an opposition
to a proposed change in control.
 
    VOTE REQUIREMENT FOR CALLING SPECIAL MEETING.  The Bylaws also contain a
provision requiring the vote of the holders of two-thirds of the outstanding
Common Stock in order to call a special meeting of stockholders. This provision
would prevent a stockholder with less than a two-thirds interest from calling a
special meeting to consider a merger unless such stockholder had first garnered
adequate support from a sufficient number of other stockholders.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
    LIMITATIONS OF DIRECTOR LIABILITY.  Section 102 (b) (7) of the DGCL
authorizes corporations to limit or to eliminate the personal liability of
directors to corporations and their stockholders for monetary damages for breach
of directors' fiduciary duty of care. Although Section 102(b) of the DGCL does
not change directors' duty of care, it enables corporations to limit available
relief to equitable remedies such as injunction or rescission. The Certificate
of Incorporation limits the liability of directors to the Company or its
stockholders to the full extent permitted by such Section 102(b). Specifically,
directors of the Company are not to be personally liable for monetary damages
for breach of a director's fiduciary duty as a director, except for liability:
(i) for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for unlawful

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Offering, the Company will have outstanding
shares of Common Stock (     shares, if the Underwriters' over-allotment option
is exercised in full, excluding      shares reserved for issuance upon the
exercise of outstanding stock options). Of these shares, all of the      shares
sold in the Offering (     shares, if the Underwriters' over-allotment option is
exercised in full) will be freely tradable without restriction or further
registration under the Securities Act, unless held by "affiliates" of the
Company as that term is defined in Rule 144 under the Securities Act. The
remaining      shares outstanding are "restricted securities" as that term is
defined under Rule 144 and were issued by the Company in one or more private
transactions in reliance upon one or more exemptions under the Securities Act.
Such restricted securities may not be resold in the public market in the absence
of registration under the Securities Act or the availability of an exemption
from such registration, including the exemption provided by Rule 144.
 
    In general, under Rule 144 a person (or persons whose shares are
aggregated), including an affiliate of the Company, who has beneficially owned
restricted securities for at least one year is entitled to sell within any
three-month period a number of shares that does not exceed the greater of the
average weekly trading volume during the four calendar weeks preceding such sale
or 1% of the then outstanding shares of Common Stock, provided certain manner of
sale and notice requirements and requirements as to the availability of current
public information about the Company are satisfied. In addition, affiliates of
the Company must comply with the restrictions and requirements of Rule 144,
other than the one-year holding period, to sell unrestricted shares of Common
Stock. A person who is deemed not to have been an "affiliate" of the Company at
any time during the 90 days preceding a sale by such person, and who has
beneficially owned such shares for at least two years, would be entitled to sell
such shares without regard to the limitations described above. Taking into
consideration the effect of the 180-day lock-up agreements described below,
approximately      restricted shares of Common Stock will be eligible for sale
in the public market immediately after the Offering and all      remaining
restricted shares will be eligible for sale upon the expiration of the 180-day
lock-up agreements, in each case subject to the volume and other limitations of
Rule 144.
 
    In addition to the outstanding shares of Common Stock, the Company has
reserved for issuance      shares of Common Stock pursuant to the Company's
stock option and employee stock purchase plans, under which options to purchase
     shares will be outstanding upon completion of the Offering. The Company
intends to register on Form S-8 under the Securities Act as soon as practicable
on and after the effective date of the Offering all of the      shares reserved
for issuance pursuant to these plans. This registration statement will be
effective upon filing. Shares registered and issued pursuant to this
registration statement will be freely tradable except to the extent that the
holders thereof are deemed to be affiliates of the Company, in which case the
transferability of such shares will be subject to the volume limitations of Rule
144, and except to the extent that the holders thereof are subject to the
lock-up agreements described below.
 
    Subject to certain exceptions, the Company, its directors and executive
officers and certain holders of outstanding shares of Common Stock and optionees
holding options to purchase a total of      shares of Common Stock have agreed,
subject to certain exceptions, with the Underwriters not to sell or otherwise
dispose of any shares of Common Stock, any options to purchase Common Stock or
any securities convertible into or exchangeable for shares of Common Stock for a
period of 180 days after the date of this Prospectus without the prior written
consent of Hambrecht & Quist LLC.
 
    Following the consummation of the Offering and subject to the lock-up
agreements, certain stockholders will be entitled to require the Company to
register under the Securities Act a total of      shares of outstanding Common
Stock (the "Registrable Shares"). In addition, in the event the Company proposes
to register any of its securities under the Securities Act, either for its own
account or for the account of a security holder, such stockholders may be
entitled to include the Registrable Shares in such registration, subject to
certain limitations on the number of shares to be included in the registration
by the underwriter of such Offering. See "Certain Transactions--Registration
Rights Agreement."
 
    Sales of substantial amounts of shares of Common Stock in the public market,
or the perception that such sale might occur, could adversely affect the market
price of the Common Stock and could impair the Company's future ability to raise
capital through an offering of its equity securities. See "Risk Factors-Shares
Eligible for Future Sale."

</TABLE>
 
    The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent, including the absence of any
material adverse change in the Company's business and the receipt of certain
certificates, opinions and letters from the Company and its counsel and
independent auditors. The nature of the Underwriters' obligation is such that
they are committed to purchase all shares of Common Stock offered hereby if any
of such shares are purchased.
 
    The Underwriters propose to offer the shares of Common Stock directly to the
public at the initial public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession not in excess
of $        per share. The Underwriters may allow, and such dealers may reallow,
a concession not in excess of $        per share to certain other dealers. After
the initial public offering of the shares, the offering price and other selling
terms may be changed by the Representatives. The Representatives have informed
the Company that the Underwriters do not intend to confirm sales to accounts
over which they exercise discretionary authority.
 
    The Company has granted to the Underwriters an option, exercisable no later
than 30 days after the date of this Prospectus, to purchase up to
     additional shares of Common Stock at the initial public offering price,
less the underwriting discount, set forth on the cover page of this Prospectus.
To the extent that the Underwriters exercise this option, each of the
Underwriters will have a firm commitment to purchase approximately the same
percentage thereof that the number of shares of Common Stock to be purchased by
it shown in the table above bears to the total number of shares of Common Stock
offered hereby. The Company will be obligated, pursuant to the option, to sell
shares to the Underwriters to the extent the option is exercised. The
Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of Common Stock offered hereby.
 
    The Offering of the shares is made for delivery when, as and if accepted by
the Underwriters and subject to prior sale and to withdrawal, cancellation or
modification of the Offering without notice. The Underwriters reserve the right
to reject an order for the purchase of shares in whole or in part.
 
    The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, and to contribute
to payments the Underwriters may be required to make in respect thereof.

    The executive officers and directors of the Company and certain
stockholders, have executed lock-up agreements in which they have agreed that
they will not, without the prior written consent of Hambrecht & Quist LLC,
directly or indirectly, offer, sell, pledge, contract to sell (including any
short sale), grant any option to purchase or otherwise dispose of any shares of
Common Stock (including, without limitation, shares of Common Stock which may be
deemed to be beneficially owned by the parties to the lock-up agreements in
accordance with the rules and regulations of the Securities and Exchange
Commission and shares of Common Stock which may be issued upon exercise of a
stock option or warrant or conversion of any convertible securities) or enter
into any short sale (whether or not against the box) or any purchase, sale or
grant of any right (including without limitation, any put or call option) with
respect to any security (other than a broad-based market basket or index) that
includes, relates to or derives any significant part of its value from the
Common Stock (each of the foregoing referred to as a "Disposition") for a period
from the date hereof and continuing until 180 days after the effective date of
the registration statements relating to the initial Public Offering (the
"Lock-Up Period"). The lock-up agreements are intended to preclude the Company's
officers, directors and certain of its stockholders from engaging in any
transaction which is designed to or reasonably expected to lead to or result in
a Disposition during the Lock-Up Period even if the securities would be disposed
of by someone other than the parties to the lock-up agreements. Sales of such
shares in the future could adversely affect the market price of the Common
Stock. Hambrecht & Quist LLC may, in its sole discretion, release any of the
shares subject to the lock-up agreements at any time without notice.
 
    Prior to the offering, there has been no public market for the Common Stock.
The initial public offering price for the Common Stock will be determined by
negotiation between the Company and the Representatives. Among the factors
considered in determining the initial public Offering price will be prevailing
market conditions, revenues and earnings of the Company, market valuations of
other companies engaged in activities similar to those of the Company, estimates
of the business potential and prospects of the Company, the present state of the
Company's business operations, the Company's management and other factors deemed
relevant.
 
    Certain persons participating in this Offering may overallot or effect
transactions which stabilize, maintain or otherwise affect the market price of
the Common Stock at levels above those which might otherwise prevail in the open
market, including by entering stabilizing bids, effecting syndicate covering
transactions or imposing penalty bids. A stabilizing bid means the placing of
any bid or effecting of any purchase, for the purpose of pegging, fixing or
maintaining the price of the Common Stock. A syndicate covering transaction
means the placing of any bid on behalf of the underwriting syndicate or the
effecting of any purchase to reduce a short position created in connection with
the Offering. A penalty bid means an arrangement that permits the Underwriters
to reclaim a selling concession from a syndicate member in connection with the
Offering when shares of Common Stock sold by the syndicate member are purchased
in syndicate covering transactions. Such transactions may be effected on the
Nasdaq Stock Market, in the over-the-counter market, or otherwise. Such
stabilizing, if commenced, may be discontinued at any time.
 
                                 LEGAL MATTERS
 
    Certain legal matters with respect to the validity of the issuance of the
shares of Common Stock offered hereby will be passed upon for the Company by
Alston & Bird LLP, Atlanta, Georgia. Certain other matters in connection with
this Offering will be passed upon for the Underwriters by Goodwin, Procter &
Hoar LLP, Boston, Massachusetts.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Accredo Health, Incorporated
 
    We have audited the accompanying consolidated balance sheets of Accredo
Health, Incorporated (formerly Nova Holdings, Inc.) (the "Company") as of June
30, 1997 and 1998, and the related consolidated statements of operations,
stockholders' equity and mandatorily redeemable cumulative preferred stock, and
cash flows for the period from inception (May 24, 1996) through June 30, 1996,
and for the years ended June 30, 1997 and 1998. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Accredo
Health, Incorporated at June 30, 1997 and 1998, and the results of its
operations and its cash flows for the period from inception (May 24, 1996)
through June 30, 1996, and for the years ended June 30, 1997 and 1998, in
conformity with generally accepted accounting principles.
 
                                                               Ernst & Young LLP

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND NATURE OF OPERATIONS
 
ORGANIZATION AND PRINCIPLES OF CONSOLIDATION
 
    Accredo Health, Incorporated (formerly Nova Holdings, Inc.) (the Company)
was incorporated on May 24, 1996. As more fully described in Note 3, on May 31,
1996, the Company acquired Southern Health Systems, Inc. (a holding company) and
its wholly-owned subsidiary, Nova Factor, Inc. Since the Company was newly
formed at May 24, 1996, and because Nova Factor, Inc. had been in existence for
several years, the Company is considered the successor to Nova Factor Inc.'s
operations.
 
    The consolidated financial statements include the accounts and transactions
of the Company and its subsidiaries for the period from inception (May 24, 1996)
through June 30, 1998, and its subsidiary Horizon Health Systems, Inc. (HHS) for
the period from its acquisition, June 1, 1997, through June 30, 1998.
Significant intercompany accounts have been eliminated in consolidation.
 
DESCRIPTION OF BUSINESS
 
    The Company provides specialized contract pharmacy and related services
beneficial to patients with certain costly chronic diseases. Because of the
unique needs of patients suffering from chronic diseases, biotechnology drug
manufacturers have recognized the benefits of customized programs to facilitate
alternate site drug administration, ensure compliance with treatment regimens,
provide reimbursement assistance and capture valuable clinical and patient
demographic information. The Company addresses the needs of the manufacturers by
providing specialized services that facilitate product launch and patient
acceptance including timely drug utilization and patient compliance information,
patient education and monitoring, reimbursement expertise and overnight drug
delivery.
 
    The Company has designed its specialty services to focus primarily on
biotechnology drugs that: (i) are used on a recurring basis to treat chronic,
and potentially life threatening diseases; (ii) are expensive; (iii) are
administered through injection; and (iv) require temperature control or other
specialized handling as part of their distribution process. Currently, the
Company provides specialized contract pharmacy and related services that address
the needs of patients with the following diseases: Gaucher Disease, a hereditary
liver enzyme deficiency; hemophilia, a hereditary bleeding disorder; Multiple
Sclerosis, a debilitating disease of the central nervous system; and growth
hormone related disorders. These diseases generally require life-long therapy,
except for the treatment of growth hormone-related disorders which typically
require treatment for six to ten years.
 
    Other revenues primarily consist of management fees from biotech
manufacturers and various management agreements with hospitals and joint
ventures.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with an initial maturity
of three months or less to be cash equivalents.
 
PATIENT ACCOUNTS RECEIVABLE
 
    The Company's primary concentration of credit risk is patient accounts
receivable, which consists of amounts owed by various governmental agencies,
insurance companies and private patients. The Company manages the receivables by
regularly reviewing its accounts and contracts and by providing appropriate
 
                                      F-7

allowances for uncollectible amounts. Significant concentrations of gross
patient accounts receivable consist of the following at June 30:

Medicare.......................................................           5%           3%
Medicaid.......................................................          17%          23%
</TABLE>
 
    Concentration of credit risk relating to accounts receivable is limited to
some extent by the diversity and number of patients and payors and the
geographic dispersion of the Company's operations The Company grants credit
without collateral to its patients.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (first-in, first-out method) or
market.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying value of receivables, accounts payable and notes payable
approximates fair value of these financial instruments at June 30, 1997 and
1998.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment is stated at cost. Provisions for depreciation are
computed primarily by the straight-line method based on the estimated useful
lives of the related assets of 2 to 7 years.
 
GOODWILL AND OTHER INTANGIBLE ASSETS
 
    Goodwill represents the excess of the cost of businesses acquired over fair
value of net tangible and identifiable intangible assets at the date of
acquisition. The Company recorded $23,396,095 in goodwill and $1,000,000 in
non-compete agreements on June 1, 1997, and $35,780,242 in goodwill, $1,117,783
in non-compete agreements and $361,416 in other intangible assets on May 31,
1996, in connection with business acquisitions. These assets are being amortized
using the straight-line method over their estimated useful lives of 40 years for
goodwill, 3 and 10 years for the non-compete agreements, and 10 years for the
other intangible assets. Goodwill is net of accumulated amortization of
$1,017,788 and $2,497,196 at June 30, 1997 and 1998, respectively. Non-compete
agreements and other intangible assets are net of accumulated amortization of
$459,115 and $1,078,291 at June 30, 1997 and 1998, respectively.
 
VALUATION OF LONG-LIVED ASSETS
 
    Management periodically evaluates carrying values of long-lived assets,
including property and equipment, strategic investments, goodwill and other
intangible assets, to determine whether events and circumstances indicate that
these assets have been impaired. An asset is considered impaired when
undiscounted cash flows to be realized from such asset are less than its
carrying value. In that event, a loss is determined based on the amount the
carrying value exceeds the fair market value of such asset.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
MANDATORILY REDEEMABLE CUMULATIVE PREFERRED STOCK
 
    The Company is authorized to issue up to 300,000 shares of nonvoting
mandatorily redeemable cumulative preferred stock (Series A). In connection with
its formation, the Company issued, at the $100 redemption amount, 250,000 shares
of the preferred stock on May 31, 1996, and 5,361 shares on the same date in
connection with the acquisition (see note 3), for a total of $25,536,100. The
nonvoting mandatorily redeemable cumulative preferred stock is entitled to an $8
per share annual dividend. Accumulated unpaid dividends of $2,213,121 and
$4,256,009 at June 30, 1997 and 1998, respectively, are included in the
mandatorily redeemable cumulative preferred stock in the accompanying
consolidated balance sheets. Accumulated unpaid dividends are $16.67 per share
at June 30, 1998.
 
    The Company may, at its option, redeem at any time a portion or all of the
preferred stock at the redemption price of $100 per share, plus any accrued but
unpaid dividends, with the consent of the bank holding the senior debt. On May
31, 2004, the Company must purchase and redeem, at the redemption price of $100
plus any accrued and unpaid dividends, all the then outstanding shares of the
redeemable preferred stock. If at any time the Company consummates a public
offering of its common stock, the Company shall apply any net cash proceeds of
such offering to redeem, at the redemption price, shares of the preferred stock.
 
STOCK-BASED COMPENSATION
 
    The Company recognizes stock-based compensation using the intrinsic value
method as permitted by Financial Accounting Standards Board Statement No. 123,
ACCOUNTING FOR STOCK-BASED COMPENSATION (Statement 123). Accordingly, no
compensation expense is recorded for stock-based awards issued at market value
at the date such awards are granted. The Company makes pro forma disclosures of
net income as if the market-value method was followed.
 
REVENUE RECOGNITION
 
    Net patient service revenues are reported at the net amounts billed to
patients, third-party payors and others in the period the services are rendered.
The Company has agreements with certain third-party payors that provide for
payments to the Company at amounts discounted from its established rates.
 
    Approximately 18%, 17% and 20% of gross patient service revenues for the
periods ended June 30, 1996, 1997 and 1998, respectively, is from participation
in the Medicare and state-sponsored Medicaid programs.
 
INTEREST RATE SWAP AGREEMENTS
 
    The Company enters into interest rate swap agreements as a means of managing
its interest rate exposure. The differential to be paid or received is
recognized over the life of the agreement as an adjustment to interest expense.
 
NET EARNINGS (LOSS) PER SHARE
 
    In 1997, the Financial Accounting Standards Board (FASB) issued Statement
No. 128. Earnings per Share. Statement 128 replaced the calculation of primary
and fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously

NET EARNINGS (LOSS) PER SHARE (CONTINUED)
 
reported fully diluted earnings per share. All earnings per share amounts for
all periods have been presented to conform to Statement 128 requirements.
 
USE OF ESTIMATES
 
    The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the consolidated
financial statements and accompanying notes. Actual results could differ from
those estimates. Estimates are used primarily in recording the allowance for
doubtful accounts.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In June 1997, the Financial Accounting Standards Board issued Statement No.
131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. The
Statement changes the way public companies report segment information in
financial statements and also requires those companies to report selected
segment information in interim financial reports to shareholders. The Statement
is effective for the Company beginning with its June 30, 1999, financial
statements. The Statement affects only disclosures presented in the financial
statements and will have no effect on consolidated financial position or results
of operations.
 
    In June 1998, the Financial Accounting Standards Board issued Statement No.
133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES, which is
required to be adopted in years beginning after June 15, 1999. Management of the
Company does not anticipate that the adoption of the new Statement will have a
significant effect on results of operations or the financial position of the
Company.
 
3. BUSINESS ACQUISITIONS
 
    On May 31, 1996, the Company acquired all of the outstanding shares of
Southern Health Systems, Inc. (SHS) common stock. SHS was a holding company
whose wholly-owned operating subsidiary was Nova Factor, Inc. In connection with
the acquisition of SHS common stock, the Company paid cash of $39,169,291 and
issued 107,253 shares of the Company's common stock and 5,361 shares of the
Company's mandatorily redeemable preferred stock with a value of $857,858. Total
assets acquired and liabilities assumed were $27,537,936 and $24,210,786,
respectively. This transaction was recorded by the Company using the purchase
method of accounting. The excess of the total purchase price of $40,586,591,
including acquisition costs of $559,442, over the fair market value of the net
assets acquired of $3,327,150 was allocated to goodwill and other identifiable
intangible assets. The Company recorded $35,780,242 in goodwill, $1,117,783 in
non-compete agreements and $361,416 in other intangible assets which are
included in the accompanying consolidated balance sheet.
 
    On June 1, 1997, the Company acquired substantially all the assets of HHS, a
Company engaged in the sale and distribution of blood clotting factors and
ancillary supplies to hemophilia patients, through an acquisition accounted for
using the purchase method of accounting. The consideration paid by the Company
related to this acquisition was $29,996,127. Total assets acquired and
liabilities assumed were $9,018,540 and $3,152,031, respectively. This
transaction was recorded by the Company using the purchase method of accounting.
The excess of the purchase price of $24,396,095, including acquisition costs of
$266,477, over the fair market value of the net assets acquired, was allocated
to goodwill and other identifiable intangible assets. The operating results of
HHS are included in the Company's consolidated statement of operations beginning
June 1, 1997.

5. NOTES PAYABLE
 
    At June 30, 1998, the Company has a revolving line of credit agreement for
up to $40 million with banks, which expires October 31, 1999. The Company's
borrowing base, as defined in the agreement, was approximately $33,155,000 and
$39,843,000 at June 30, 1997 and 1998, respectively. Amounts outstanding under
the line of credit bear interest at varying rates based upon a LIBOR or prime
rate of interest at the periodic election of the Company plus a variable margin
rate based on the Company's debt to cash flow ratio as defined by the banks (the
combination of a 2% margin and LIBOR base rate resulted in effective rates of
7.69% at June 30, 1997 and 7.625% at June 30, 1998). The Company entered into an
interest rate swap agreement with a bank in October 1997 in order to fix a
portion of its interest rate exposure on this line of credit. The terms of the
agreement require the Company to pay a fixed interest rate of 6.15% on a $15
million notional amount and receive the 30 day LIBOR rate in exchange. The
interest rate swap agreement terminates October 29, 1999. The line of credit is
secured by substantially all assets of the Company. The bank's security interest
in a portion of the Company's inventory is subordinate to the liens on that
inventory under the terms of a security agreement between the Company and one of
its vendors. The same vendor has a security interest in certain accounts
receivable of the Company which is subordinate to the rights of the banks. At
June 30, 1998, the balance outstanding under this line of credit was
$27,497,725.
 
    As defined in the credit agreements, the line of credit contains financial
covenants which require the Company to maintain certain levels of net worth,
tangible net worth, working capital, debt to net worth and liquidity ratios. The
credit agreement also restricts certain changes in management and ownership of
the Company.
 
    During June 1997, the Company issued $10 million in senior subordinated
notes (the Notes) to certain stockholders of the Company in connection with the
purchase of HHS. The Notes, which are due June 1, 2004,

have a stated interest rate of 10% and an effective rate of 16%. The Notes are
unsecured. Concurrently with the issuance of the Notes, the Company issued
400,000 shares of its common stock to the Note holders. The excess of the fair
market value of the 400,000 shares of common stock issued over the purchase
price of $4,000 was recorded as an original issue discount. This original issue
discount, which accretes over the life of the related obligation using the
effective interest method, is reflected as a reduction of the Notes in the
accompanying consolidated balance sheets.
 
    At the option of the Company, the amount of interest due and payable
September 1, 1998; December 1, 1998; March 1, 1999 and June 1, 1999, may be
added to the unpaid principal balance of the Notes. During 1997 and 1998, the
Company added $85,009 and $1,045,826, respectively, of accrued interest due
during 1997 and 1998 to the unpaid principal balance of the Notes.
 
    If at any time while the Notes are outstanding, the Company shall consummate
a public offering, as defined in the note purchase agreement, or merge or
consolidate, as defined in the note purchase agreement, the Company shall use
the net proceeds of such offering to repay the principal amount of the Notes,
plus accrued interest (see Note 12). On any interest payment date on or after
June 1, 2002, the Company shall pay an amount of accrued original issue discount
on the Notes as shall be necessary to ensure that such Notes shall not be
considered applicable high yield discount obligations as defined in the note

    The liability method is used in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse. The Company is indemnified for income tax
liabilities arising prior to May 31, 1996, by its former parent.
 
    Income tax expense (benefit) consist of the following for the periods ended
June 30:

common stock. All options granted have 10-year terms and vest and become fully
exercisable over a period of 1 to 6 years of continued employment. Certain
options granted with up to 6-year vesting terms also have provisions for
accelerated vesting over the first 4 years if certain Company income targets are
achieved during that period. Otherwise, these options become fully exercisable
at the end of up to 6 years of continued employment.
 
    Pro forma information regarding net income is required by Statement 123 and
has been determined as if the Company had accounted for its employee stock
options under the fair value method of Statement 123. Significant assumptions
used by the Company in the Black-Scholes option pricing model computations are
as follows for the periods ended June 30:

</TABLE>
 
    The Black-Scholes option model was developed for use in estimating the fair
value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information for the periods ended June 30 is as follows:

11. EARNINGS PER SHARE (CONTINUED)
(1) Historical diluted loss per share amounts for 1996 and 1997 have been
    calculated using the same denomination as used in the basic loss per share
    calculation as the inclusion of dilutive securities in the denominator would
    have an anti-dilutive effect.
 
12. SUBSEQUENT EVENTS
 
PUBLIC OFFERING

                         NOTES TO FINANCIAL STATEMENTS
 
                     ELEVEN-MONTH PERIOD ENDED MAY 31, 1996
 
1. ORGANIZATION AND NATURE OF OPERATIONS
 
ORGANIZATION
 
    Nova Factor, Inc. (the Company) is a wholly-owned subsidiary of Southern
Health Systems, Inc. (SHS), a holding company. Prior to May 31, 1996, Le Bonheur
Health Systems, Inc. was the majority shareholder of SHS. On May 31, 1996,
Accredo Health, Incorporated (Accredo) (formerly Nova Holdings, Inc.) purchased
from Le Bonheur Health Systems, Inc. all of the outstanding shares of SHS common
stock. The financial statements reflect the historical cost-basis financial
statements of the Company, the predecessor to Accredo, prior to the acquisition.
 
DESCRIPTION OF BUSINESS
 
    The Company provides specialized contract pharmacy and related services
beneficial to patients with certain costly chronic diseases. Because of the
unique needs of patients suffering from chronic diseases, biotechnology drug
manufacturers have recognized the benefits of customized programs to facilitate
alternate site drug administration, ensure compliance with treatment regimens,
provide reimbursement assistance and capture valuable clinical and patient
demographic information. The Company addresses the needs of the manufacturers by
providing specialized services that facilitate product launch and patient
acceptance including timely drug utilization and patient compliance information,
patient education and monitoring, reimbursement expertise and overnight drug
delivery.
 
    The Company has designed its specialty services to focus primarily on
biotechnology drugs that: (i) are used on a recurring basis to treat chronic,
and potentially life threatening diseases; (ii) are expensive; (iii) are
administered through injection; and (iv) require temperature control or other
specialized handling as part of their distribution process.
 
    Other revenues primarily consist of management fees from biotech
manufacturers and various management agreements with hospitals and joint
ventures.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
    Net patient service revenues are reported at the net amounts billed to
patients, third-party payors and others in the period the services are rendered.
The Company has agreements with certain third party-payors that provide for
payments to the Company at amounts discounted from its established rates.
 
    Approximately 18% of gross patient service revenue for the eleven-month
period ended May 31, 1996, is from participation in the Medicare and
state-sponsored Medicaid programs. The Company grants credit without collateral
to its patients.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (first-in, first-out method) or
market.

                     ELEVEN-MONTH PERIOD ENDED MAY 31, 1996
 
2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
DEPRECIATION
 
    Provisions for depreciation are computed by the straight-line method based
on the estimated useful lives of the related assets of 2 to 7 years.
 
USE OF ESTIMATES
 
    The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates. Estimates are used primarily in recording the allowance for doubtful
accounts.
 
3. INCOME TAXES
 
    The liability method is used in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax basis of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse. The Company is indemnified for income tax
liabilities arising prior to May 31, 1996, by Le Bonheur Health Systems, Inc.,
SHS's former parent.
 
    SHS files a consolidated federal income tax return. Financial Accounting
Standards Board Statement 109, ACCOUNTING FOR INCOME TAXES, requires the
allocation of federal income tax expense to the members of a control group that
file a consolidated income tax return for federal income tax purposes.
Therefore, SHS allocated federal income tax benefits of $72,090 to the Company
for the eleven-month period ended May 31, 1996, as if a separate federal income
tax return were filed for the Company.
 
    Income tax (expense) benefit consists of the following for the period ended
May 31, 1996:

5. DEFINED CONTRIBUTION PLAN
 
    The Company participates in a qualified defined contribution plan of SHS,
under Section 401(k) of the Internal Revenue Code (IRC). Substantially all full
time employees qualify for participation in the plan. The Company makes matching
contributions to the employees' accounts, as defined in the plan. The Company
made matching contributions of approximately $7,500 in the eleven-month period
ended May 31, 1996.
 
6. RELATED PARTIES
 
    In connection with the sale of SHS by Le Bonheur Health Systems, Inc. on May
31, 1996, the Company declared a non-cash dividend consisting of the amount owed
to the Company by SHS at May 31, 1996 of $7,796,012 by forgiving such amounts
due from SHS. This dividend was recorded as a reduction of stockholder's equity.
Dividends on a per share basis do not provide meaningful information and are not
disclosed herein.
 
    The Company received certain services provided by SHS that include cash
management, tax reporting, risk management and executive management. Allocated
expenses for such services, amounting to $2,753,268 for the eleven-month period
ended May 31, 1996, have been included in the accompanying statement of
operations. Charges for these corporate services were based upon a general
allocation methodology determined by SHS (used to allocate all corporate
overhead expenses to SHS subsidiaries), and were not necessarily allocated based
on specific identification of expenses. Management believes the allocation
methodology is reasonable, and results in amounts that approximate the amounts
that would have been incurred on a stand-alone basis. Additionally, SHS
allocated expenses of $1,453,006 incurred in connection with the sale of the
Company to Accredo.
 
    Texas Health Pharmaceutical Resources, Teddy Bear Home Care/Drug Therapies
and Children's Memorial Home Hemophilia Services are joint ventures in which the
Company has a 50% ownership interest. These joint ventures are accounted for by
the Company under the equity method of accounting.
 
    The Company provided management services to these joint ventures of
approximately $342,000 for the eleven-month period ended May 31, 1996. The
management fees are recorded as other revenues in the accompanying statement of
operations.

ORGANIZATION
 
    Prior to June 1, 1997, Horizon Health Systems, Inc. d/b/a Hemophilia Health
Services (the Company) was organized as an S corporation. On June 1, 1997,
Accredo Health, Incorporated (formerly Nova Holdings, Inc.) acquired
substantially all of the assets of the Company and the Company became a
wholly-owned subsidiary of Accredo Health, Incorporated.
 
DESCRIPTION OF BUSINESS
 
    The Company is engaged in the sale and distribution of clotting factors and
ancillary supplies to hemophilia patients located throughout the United States.
The Company provides value-added clinical and distribution services to patients
and payors such as insurance companies, health maintenance organizations, self
insured employers and through the federal Medicare and state-funded health care
programs.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
    Net patient service revenues are reported at the net amounts billed to
patients, third-party payors and others in the period the services are rendered.
The Company has agreements with certain third-party payors that provide for
payments to the Company at amounts discounted from its established rates. The
Company grants credit without collateral to its patients.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (first-in, first-out method) or
market.
 
DEPRECIATION AND AMORTIZATION
 
    Provisions for depreciation and amortization are computed principally by
accelerated and straight-line methods based on the estimated useful lives of the
related assets of 5 to 7 years.
 
USE OF ESTIMATES
 
    The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.
 
3. INCOME TAXES
 
    The Company, with the consent of its shareholders, has elected to be an S
Corporation under the Internal Revenue Code. Instead of the Company paying
federal corporate income taxes, the stockholders are taxed individually on the
Company's taxable income. Therefore no provision for federal income taxes has
been made. The Company is liable for state franchise and excise taxes and,
accordingly, a provision has been made for such taxes.

4. OPERATING LEASES
 
    The Company leases office space and equipment under various operating
leases. Rent expense for all operating leases was approximately $274,000 and
$226,000 for the years ended December 31, 1995 and 1996, respectively.
 
    Future minimum payments, by year and in the aggregate, under noncancelable

5. RELATED PARTIES
 
    The Company leased office space from the President and 79% owner of the
Company prior to June 1, 1997. Monthly payments on the lease, which expires
November 1999, are $17,988.
 
6. NOTES PAYABLE
 
    At December 31, 1995, the Company had a promissory note with a bank for
$750,000. The note carried interest at the bank's prime rate plus an additional
amount based on the Company's leverage rate, ranging from 0.25% to 1.0% (9.5% at
December 31, 1995). The note was paid in full during 1996.
 
7. UNAUDITED INTERIM FINANCIAL STATEMENTS
 
    The unaudited financial statements for the three-month periods ended March
31, 1996 and 1997, have been prepared in accordance with generally accepted
accounting principles for interim financial information and Article 10 of
Regulation S-X. Accordingly, they do not include all the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments, consisting
of recurring adjustments, necessary for a fair presentation have been included.
Operating results for the three-month periods ended March 31, 1996 and 1997, are
not necessarily indicative of the results that may be expected for the entire
year.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Partners
Texas Health Pharmaceutical Resources
 
    We have audited the accompanying balance sheet of Texas Health
Pharmaceutical Resources (the Partnership) as of June 30, 1997, and the related
statements of operations, partners' equity and cash flows for the year then
ended. These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Texas Health Pharmaceutical
Resources at June 30, 1997, and the results of its operations and cash flows for
the year then ended in conformity with generally accepted accounting principles.

                        (UNAUDITED AS TO 1996 AND 1998)
                    YEARS ENDED JUNE 30, 1996, 1997 AND 1998
 
1. ORGANIZATION AND NATURE OF OPERATIONS
 
ORGANIZATION
 
    Texas Health Pharmaceutical Resources (the Partnership) is a general
partnership formed on July 1, 1994. The Partnership has two general partners,
Nova Factor, Inc. (NFI) and Alternative Care Systems, Inc. (ACS), each of which
has a 50% ownership interest and shares equally in the profits and losses of the
Partnership. Under the partnership agreement, the partnership term will end on
March 31, 1999, unless extended by mutual agreement of the partners.
 
DESCRIPTION OF BUSINESS
 
    The purpose of the Partnership is to provide specialized contract pharmacy
services beneficial to patients with certain costly chronic diseases. The
Partnership markets, sells and distributes drugs such as growth hormone and
provides hemophilia therapy services and supplies.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
CASH AND CASH EQUIVALENTS
 
    The Partnership considers all highly liquid investments with an initial
maturity of three months or less to be cash equivalents.
 
PATIENT ACCOUNTS RECEIVABLE
 
    The Partnership's primary concentration of credit risk is patient accounts
receivable, which consists of amounts owed by various governmental agencies,
insurance companies and private patients. The Partnership manages the
receivables by regularly reviewing its accounts and contracts and by providing
appropriate allowances for uncollectible accounts. Significant concentrations of
gross patient accounts receivable are as follows at June 30:

                                                                            1997
                                                                          ---------     1998
                                                                                     -----------
                                                                                     (UNAUDITED)
<S>                                                                       <C>        <C>
Medicare................................................................        24%         14%
Medicaid................................................................        29%         32%
</TABLE>
 
    Concentration of credit risk relating to accounts receivable is limited to
some extent by the diversity and number of patients and payors, and could be
adversely affected by the geographic service area of the business which, under
the partnership agreement, is the area encompassed within the 50-mile radius of
Dallas, Texas, and within the city limits of Lubbock, Texas. The Partnership
grants credit without collateral to its patients.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (first-in, first-out method) or
market.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying value of receivables and accounts payable approximates fair
value of these financial instruments.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                        (UNAUDITED AS TO 1996 AND 1998)
                    YEARS ENDED JUNE 30, 1996, 1997 AND 1998
 
2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
FURNITURE AND EQUIPMENT
 
    Furniture and equipment are stated at cost. Provisions for depreciation are
computed by the straight-line method based on the estimated useful lives of the
related assets of three to seven years.
 
REVENUE RECOGNITION
 
    Net patient service revenues are reported at the net amounts billed to
patients, third-party payors and others in the period the services are rendered.
The Partnership has agreements with certain third-party payors that provide for
payments to the Partnership at amounts discounted from its established rates.
Approximately 59% (unaudited), 63% and 63% (unaudited) of gross patient service
revenues for the years ended June 30, 1996, 1997 and 1998, respectively, are
from participation in the Medicare and state-sponsored Medicaid programs.
 
    Other revenues primarily consist of management fees.
 
USE OF ESTIMATES
 
    The preparation of financial statements requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates. Estimates are used primarily in recording the allowances for doubtful
accounts.
 
3. OPERATING LEASES
 
    The Partnership leases office space and equipment under various operating
leases. Rent expense for all operating leases was approximately $1,700
(unaudited), $15,000 and $15,000 (unaudited), for the years ended June 30, 1996,
1997 and 1998, respectively.
 
    Future minimum payments, by year and in the aggregate, under noncancelable
operating leases with terms of one year or more, consist of the following for
the years ended June 30:

                                                                     $  27,000
                                                                     ---------
                                                                     ---------
</TABLE>
 
4. RELATED PARTIES
 
    During 1996, the Partnership forgave $1,635,143 (unaudited) of amounts due
from affiliates in which ACS and an affiliate of NFI were each 50% partners. Due
from affiliates of $183,239 and $192,096 (unaudited) at June 30, 1997 and 1998,
respectively, consists of accounts receivable from other entities affiliated
with NFI.
 
    The Partnership receives certain services provided by NFI that include cash
management, tax reporting, risk management, executive management, computer
processing, and accounting and reimbursement services. For these services, the
Partnership pays management, reimbursement and accounting fees to NFI.
Management, accounting and reimbursement fees were $771,085 (unaudited),
$245,967 and $194,198 (unaudited) for the years ended June 30, 1996, 1997 and

5. INCOME TAXES
 
    No provision is made in the accounts of the Partnership for federal and
state income taxes, as such taxes are liabilities of the partners. The
Partnership's tax returns and amounts of allocable Partnership revenues and
expenses are subject to examination by federal and state taxing authorities. If
such examinations occur and result in changes, the portion of the Partnership's
income or loss reported by the partners may also change.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Company's Amended and Restated Certificate of Incorporation provides
that the Company shall, to the fullest extent permitted by Section 145 of the
DGCL, as amended from time to time, indemnify its officers and directors.
 
    Section 145 of the DGCL permits a corporation, under specified
circumstances, to indemnify its directors, officers, employees or agents against
expenses (including attorney's fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by them in connection with any
action, suit or proceeding brought by third parties by reason of the fact that
they were or are directors, officers, employees or agents of the corporation, if
such directors, officers, employees or agents acted in good faith and in a
manner they 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
reason to believe their conduct was unlawful. In a derivative action, i.e., one
by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agents in connection with the defense or settlement of any action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnity for such expenses despite
such adjudication of liability.
 
    The Company's Amended and Restated Certificate of Incorporation contains a
provision which eliminates, to the fullest extent permitted by the DGCL,
director liability for monetary damages for breaches of the fiduciary duty of
care or any other duty as a director.
 
    The Company intends to purchase a policy of director's and officer's
insurance that would in certain instances provide the funds necessary for the
Company to meet its indemnification obligations under its Amended and Restated
Certificate of Incorporation.

indemnify the Underwriters and certain other persons against certain
liabilities.

ITEM 17. UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company 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 Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    The undersigned registrant hereby undertakes to provide to the
Representatives of the Underwriters at the closing specified in the underwriting
agreements certificates in such denominations and registered in such names as
required by the Representatives of the Underwriters to permit prompt delivery to
each purchaser.
 
    The undersigned registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this Registration Statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.

Section 3.  Distribution of Genentech HGH

3.1  Dispensing Obligation. Subject to Section 4.1 of this Agreement and to 
the extent in accordance with applicable laws and regulations, Nova Factor 
shall evaluate the reimbursement status of, and dispense Genentech HGH to, 
all patients with a prescription for Genentech HGH who are referred by any 
person or entity to Nova Factor. Within three (3) business days of Nova 
Factor's receipt of each prescription or other appropriate shipment request, 
Nova Factor shall dispense Genentech HGH to patients without regard to third 
party payer coverage of such patient's Genentech HGH; provided, however, that 
if the patient or physician specifically requests a delay in dispensing or if 
prior authorization is required for a Government Program patient, both as 
documented by written records of Nova Factor, said (3) day time frame 
shall not apply, and Nova Factor shall use its commercially reasonable best 
efforts to ship the requested Genentech HGH within thirty (30) days of such 
prescription or shipment request.

3.2  Exceptions. Notwithstanding Section 3.1 above, Nova Factor shall not be 
obligated to dispense Genentech HGH to patients:

     (a) having no insurance or other third party payer coverage (or coverage 
     equal to an amount less than * percent (*%) of Nova Factor's 
     acquisition cost for Genentech HGH for such patient) for Genentech HGH 
     after a duly diligent evaluation by Nova Factor of such patient's 
     eligibility for all reasonable payer sources, including, without 
     limitation, a Government Program, or

     (b) where the patient, physician or payer repeatedly and consistently 
     refuses to assist with the reimbursement process, to complete the 
     required documentation necessary to process the reimbursement request, 
     or to process a request for coverage, as demonstrated by: (i) a failure 
     to respond to at least three (3) consecutive Nova Factor contacts, at 
     least one (1) of which is a written contact and all of which are 
     documented in Nova Factor's written records; or (ii) a failure to 
     substantially comply with the material requirements of a contract 
     between the payer and the patient or physician; or (iii) a failure by 
     the patient to pay Nova Factor within a reasonable time frame. Nova 
     Factor agrees that it shall use its commercially reasonable best efforts 
     to remedy the refusal, including, without limitation, contacting and 
     cooperating with Genentech to resolve the issue with the patients, payer 
     or provider, and exhausting all legal options under the federal, state, 
     ERISA or other applicable reimbursement standards to resolve the 
     coverage or claim request; provided, however, that the number of 
     patients denied service by Nova Factor each calendar year under this 
     Section 3.2(b) shall not exceed two percent (2%) of the total number of 
     patients with prescriptions or

     statements of medical necessity for Genentech HGH who are referred to, 
     or dispensed or serviced by, Nova Factor during such year. In the event 
     that such number of patients exceeds or threatens to exceed two percent 
     (2%) because of factors beyond the reasonable control of the Parties, 
     then the Parties shall meet to discuss methods to remedy such problems.

3.3  Notice to Genentech. Promptly (which means Nova Factor shall use its 
commercially reasonable best efforts to notify within three (3) business 
days) after Nova Factor learns that a patient either lacks or is not 
eligible for any third party payer coverage for Genentech HGH, or at least 
fifteen (15) business days prior to Nova Factor terminating or electing not 
to ship to a patient during Appeals or due to a refusal to cooperate or 
otherwise, Nova Factor shall notify Genentech of such patient and the reasons 
for such patient's non-eligibility or lack of coverage, or for Nova Factor's 
refusal to service, as the case may be, and Genentech may provide Genentech 
HGH to such patient through its Uninsured Patient's Program or in any other 
manner Genentech chooses.

3.4  Delivery Obligations. Nova Factor shall deliver Genentech HGH to the 
home of each patient or to such other delivery point as may be designated by 
the patient. Nova Factor may distribute Genentech HGH through its Affiliates 
and, with the prior written approval of Genentech, which approval may be 
withheld at Genentech's sole discretion, other third parties; provided, 
however, that Nova Factor hereby guarantees compliance by such Affiliates and 
third parties with the terms of this Agreement.

3.5  Appeals and Collections. Nova Factor shall use its commercially 
reasonable best efforts to obtain reimbursement from the patient and/or the 
third party payer or other payer, including in the event of a denial of 
insurance coverage, prosecuting all Appeals. Said Appeals shall include at 
least the following steps unless such step is not available: (a) obtaining a 
written denial of payment which sets forth the rationale for such denial; (b) 
sending a written appeal to the third party payer setting forth 
comprehensively the nature of the appeal and providing all relevant support 
for the appeal; and (c) sending a written appeal to the next higher level of 
appeal at that third party payer. As a general matter, Nova Factor will ship 
on first level Appeals, and on second level Appeals when the clinical 
information of the patient falls within reasonable medical review criteria 
for treating growth hormone inadequacy. Nova Factor is not required to ship 
on patients with pre-existing clauses, lack of coverage for injectables, or 
no Rx coverage.

3.6  Government Programs and UPP. For each patient who does not have third 
party payer coverage or for who insurance coverage is in doubt, Nova Factor 
will promptly and diligently assess that patient's eligibility for coverage 
of Genentech HGH under all appropriate Government Programs. Nova Factor shall 
use its best


                                        9

<PAGE>

efforts to inform patients about meeting, and for patients with Government 
Program coverage, maintaining eligibility and coverage by Government 
Programs. If third party payer or Government Program coverage for Genentech 
HGH is not available, Nova Factor shall promptly contact such patient to 
determine the patient's ability to pay for the Genentech HGH with his or her 
individual funds. In the event that such patient is unable to pay for the 
Genentech HGH individually, Nova Factor shall promptly advise Genentech so 
that Genentech may consider the patient for Genentech's Uninsured Patients 
Program.

3.7  Patient Assistance Program. Nova Factor shall develop and administer a 
patient assistance program in accordance with applicable law and regulations 
to assist patients financially unable to afford Genentech HGH therapy; 
provided, however, that Nova Factor shall not have any obligation related to 
patients having no third party payer coverage for Genentech HGH therapy as 
described in Section 3.2(b), which patients may be eligible for Genentech's 
Uninsured Patients Program. Nova Factor shall develop its own financial 
criteria for patients and shall review each patient's financial status on a 
case-by-case basis, all in conformance with applicable laws, rules and 
regulations.

Section 4.  Distribution Relationship

4.1  Exclusivity. In consideration of the benefits provided to Nova Factor 
under this Agreement, Nova Factor agrees for itself not to sell and shall 
cause its Affiliates not to sell during the term of this Agreement without 
Genentech's prior written consent any product (other than Genentech HGH) 
containing human growth hormone or an analog of human growth hormone, or 
whose principal effect is that of human growth hormone, whether 
naturally-occurring or manufactured by any process. Notwithstanding the 
foregoing, Nova Factor shall have the right to distribute or sell any third 
party's human growth hormone product measured in 2x5 mg unit cartons (or 
their equivalent) (a "Third Party Unit") in a volume equal to * percent 
(*%) of the combined Nova Factor and Affiliate sales volume, in 10 mg 
equivalent units of Genentech HGH, for the preceding year. This sales volume 
shall be adjusted, in a manner mutually agreed to by Genentech and Nova 
Factor, to account for current and future Affiliate sales, in 10 mg 
equivalent units of Genentech HGH, for the preceding year, payer formulary 
restrictions, and sales of competitive product for indications for which 
Genentech HGH does not have FDA approval. Said amount may be revised upward 
or downward upon mutual agreement of Genentech and Nova Factor. At the end of 
each calendar quarter, Nova Factor shall provide a statement to Genentech 
setting forth the number of Third Party Units distributed by Nova Factor and 
its Affiliates, which amount shall be subject to audit by Genentech in 
accordance with Section 2.7(a)(9). In the event that in any year, based upon 
such quarterly reports, Nova Factor and its Affiliates distribute Third Party 
Units above the * percent (*%) limit described in


* Omitted information is the subject of a request for confidential treatment 
  pursuant to Rule 406 under the Securities Act of 1933 and has been filed 
  separately with the Securities Exchange Commission.

the second sentence of this paragraph, Nova Factor shall pay to Genentech 85% 
of Nova Factor's average purchase price of Genentech HGH during that year for 
each Third Party Unit distributed by Nova Factor or its Affiliates during 
such year in excess of said amount. Nova Factor also agrees and shall cause 
its Affiliates not to distribute or sell Genentech HGH during the term of 
this Agreement outside of the United States or its territories or possessions 
without the prior written consent of Genentech, which consent shall be given 
or withheld in Genentech's sole discretion.

4.2  Substitution and Counter-Detailing of Human Growth Hormone Products. 
Except as may be required by applicable law, Nova Factor agrees that it shall 
not substitute, generically or therapeutically, any other human growth 
hormone product(s) for prescriptions written for Genentech HGH to patients 
covered under this Agreement, but specifically excluding patients who are 
covered under a Government Program. Nova Factor and its Affiliates shall not 
counter-detail Genentech HGH. Nova Factor and its Affiliates agree not to (1) 
promote against, counter-detail, or disparage the Genentech Single Point of 
Contact system to be administered by Genentech or its subcontractor for 
patients with prescriptions of Genentech HGH, (2) promote against, 
counter-detail, or disparage the Genentech Managed Distribution System 
operated by Healthcare Delivery Systems, Inc. and implemented by Genentech 
for the distribution of Genentech HGH through a network of pharmacies 
licensed to dispense Genentech HGH ("GMDS"), or (3) promote GMDS. Nova Factor 
may inform its customers of its status as an authorized dispensing pharmacy 
within GMDS; provided, however, that Nova Factor shall not so inform its 
customers in writing unless Genentech has previously approved, in writing, 
such written materials, which approval shall not be unreasonably withheld. 
Nova Factor and its Affiliates shall not convert or attempt to convert 
patients referred to Nova Factor as a GMDS provider to another delivery 
option. Nova Factor agrees that it shall make no representation, guarantee or 
warranty about Genentech HGH, whether in writing or orally, except as is 
contained in written materials delivered to Nova Factor by Genentech for use 
in promoting and selling Genentech HGH or as may otherwise be agreed to by 
Genentech in writing. Genentech shall have the right to approve Nova Factor 
promotional materials which contain pertinent facts relative to Genentech HGH 
and all such materials shall comply with applicable regulatory requirements 
and shall not contain misrepresentations, either about Genentech HGH or a 
competitive product, or disparage a competitive product.

Section 5.  Term; Termination

5.1  Term. The term of this Agreement shall commence as of the Effective Date 
and continue through December 31, 1999, unless extended by mutual agreement 
of the Parties for additional one-year periods.


                                       11

<PAGE>

5.2  Termination Events. The foregoing notwithstanding, this Agreement may be 
terminated by a Party: (a) upon any material breach of this Agreement by the 
other Party which breach is not cured within sixty (60) days of notice by the 
non-breaching Party; or (b) immediately upon giving notice (i) upon the 
institution by or against the other Party of insolvency, receivership or 
bankruptcy proceedings or any other proceedings for the settlement of the 
other Party's debts, (ii) upon the other Party's making an assignment for the 
benefit of its creditors, or (iii) upon the other Party's dissolution. This 
Agreement may also be terminated upon mutual agreement of the Parties hereto.

5.3  Effect of Termination. Upon termination, if requested by Genentech, Nova 
Factor shall return all unused Genentech HGH to Genentech and shall be 
reimbursed by Genentech for the reasonable shipping expenses of the return 
and the purchase price of the Genentech HGH returned if the purchase price 
was previously paid by Nova Factor. If Genentech does not request such unused 
Genentech HGH to be returned, Nova Factor may sell such unused Genentech HGH 
to patients or return it to Genentech for credit. Nova Factor shall also 
return, if so requested by Genentech, all sales aids and other associated 
material supplied to Nova Factor by Genentech. Termination shall not relieve 
either Party of obligations incurred prior to termination, including Nova 
Factor's obligation to pay for Genentech HGH ordered by and delivered to it 
under this Agreement, provided that Genentech has not requested return of 
that Genentech HGH, and Genentech's obligations of reimbursements accrued as 
of the termination date under the programs described in Section 2 above, 
which obligations of reimbursement shall first be set off against obligations 
of Nova Factor to Genentech, and if any reimbursement credits remain after 
set-off after a reasonable period for reconciliation of all outstanding 
claims, shall be paid in cash. The provisions of Sections 6.6 and 6.14 shall 
survive any termination of this Agreement.

5.4  Change In Control. If Nova Factor or any of its Affiliates or all or 
substantially all of either of their assets are to be acquired by whatever 
means, including merger with or into, another entity, including an Affiliate 
(the "Acquiring Entity") Nova Factor shall so notify Genentech in writing at 
least ninety (90) days prior to the date of occurrence of such event, and 
Genentech shall have the right to terminate this Agreement at any time until 
ninety (90) days after Genentech's receipt of written notice from Nova 
Factor. In addition Genentech shall have the right to terminate this 
agreement if Nova Factor or its Affiliates acquires all or substantially all 
of the assets of an entity or a division of any entity which in either case 
sold Genentech HGH within one year preceding such purchase. Nova Factor shall 
notify Genentech in writing at least sixty (60) days prior to the occurrence 
of such event. If Genentech so


                                       12

<PAGE>

terminates this Agreement, Nova Factor agrees for itself, its Affiliates and 
for any such entity that, without Genentech's prior written consent, neither 
it nor the Acquiring Entity nor any party affiliated with either of them 
shall sell to any patient receiving Genentech HGH at the time of said 
termination, for a period of two (2) years following the date of such 
acquisition, a human growth hormone product or a product which can be 
substituted for Genentech HGH using any of the assets or facilities or 
programs developed or used by Nova Factor under this Agreement.

independent, non-profit endowment to assist financially and medically needy 
patients, with prescriptions for Genentech HGH.

Parties hereto, and supersedes any and all prior agreements between the

the Agreement shall be binding on either Party unless reduced to writing and

the requirement for such disclosure and/or request confidential treatment. 
This Section 6.6 shall survive any termination of this Agreement for a period 
of five (5) years from disclosure to the receiving Party.

6.7  Publicity. Nova Factor shall not originate any news release or public 
announcement, written or oral, to any person relating to this Agreement or to

Inventory during each calendar quarter; provided that, Nova Factor agrees 
that at the option of Genzyme it will purchase adequate amounts of 
Cerezyme-TM- to bring the Combined Inventory to a *-day level prior to the 
end of any such calendar quarter, however, in no event will such purchase 
cause the inventory to exceed an average of * days for such calendar 
quarter; provided further that in no event shall Nova Factor be required to 
have on hand Combined Inventory in excess of * dollars.  The 
calculation of inventory will be based upon the average of the unit sales 
volume for the previous month, the projected unit sales volume for the 
current month, and the projected sales volume for the next month as described

its replacement (i.e., market) value against fire, theft, loss or 
destruction, and such other risks as are customarily insured against by 
prudent persons in a similar line of business, with an insurance carrier

permit Nova factor to file claims with a third party payor, if any, or to 
submit invoices to the appropriate Cerezyme-TM- Customer.

     3.6  Distribution and Pharmacy Services.

single or multiple doses, but only if such does(s) are to be administered to 
an Approved Patient(s).  Nova Factor shall not provide Cerezyme-TM- to any 
Cerezyme-TM- Customer without the prior authorization of Genzyme.

          (c)  Pharmacy Records.  Nova Factor shall maintain such pharmacy 
records as are required by applicable federal and state laws, regulations and

or other similar method of shipment selected by Nova Factor.

          (d)  Return of Cerezyme-TM-.  In the event that a shipment of 
Cerezyme-TM- is refused or rejected by the Cerezyme-TM- Customer, Nova Factor 
will cause the shipment of Cerezyme-TM- to be returned to the Warehouse at

that:

                     (i)   Nova Factor shall assume responsibility for and 
         shall indemnify and hold Genzyme harmless and defend Genzyme from 
         all losses (including claims for injuries to employees of Nova

         of Nova Factor, its agents or employees; or (C) any 
         misrepresentation or breach of any representation or warranty made 
         herein by Nova Factor; provided, however, that Nova Factor shall 
         have no liability to Genzyme for loss of profits to Genzyme in the 
         event Nova Factor is unable, through no fault of Nova Factor's, to 
         ship Cerezyme-TM- to a Cerezyme-TM- Customer; and

                     (ii)  Genzyme shall assume responsibility for and shall 
         indemnify and hold Nova Factor harmless and defend Nova Factor from 
         all losses (including claims for injuries to employees of Nova

         this Agreement; (B) the negligent acts or omissions or wrongful acts
         of Genzyme, its agents or employees; (C) any misrepresentation or

                                       20
<PAGE>

other party. In the event of such cancellation, termination, reduction or 
change of the coverage described herein, the party maintaining such insurance 
shall immediately obtain substitute or replacement coverage. Failure to

termination of this Agreement.

         4.2   Term, Renewal and Termination.

               (a)   Initial Term. Unless otherwise terminated pursuant to 
subsection (c) below, this Agreement shall be for an initial term expiring on 
December 31, 1995 (the "Initial Term").

               (b)   Renewal. Unless otherwise terminated pursuant to 
subsection (c) below, this Agreement will automatically renew at the 
expiration of the Initial Term for an additional period of one year and shall 
thereafter automatically renew from year to year for additional one-year 
periods, unless either party shall give written notice of cancellation to the 
other party at least 90 days prior to the end of the Initial Term or the 
expiration of any extension.

               (c)   Termination. This Agreement shall automatically 
terminate (i) upon the mutual agreement of the parties, (ii) at any time upon
sixty (60) days prior notice by either party hereto, (iii) upon the insolvency 
or bankruptcy of either party, the making by either party of an assignment 
for the benefit of creditors, the consent by either party to the appointment 
of a trustee or receiver, or the appointment without its consent, of a 
trustee or receiver for it or for a substantial part of its property, or (iv) 
upon the institution by or against either party of bankruptcy, 
reorganization, arrangement or insolvency proceedings. In addition, if either 
party hereto shall breach the terms of this Agreement, the nonbreaching party

Agreement shall at the option of the nonbreaching party be terminated

                                       21
<PAGE>

immediately upon the conclusion of such 30 day period. Late payment by Nova 
Factor under the terms of Section 3.2(c) hereof shall not constitute a breach 
of the terms of this Agreement sufficient to give rise to termination of this 
Agreement.

               (d)   Return of Cerezyme-TM-. In the event of termination of 
this Agreement, Nova Factor shall cause the inventory of Cerezyme-TM- then in

for the amount due from Nova Factor for that unit, except any units which are 
destroyed or damaged for which Nova Factor shall bear the risk of loss in 
accordance with Section 3.3(d) hereof. The services fees earned by Nova 
Factor for any Cerezyme-TM- returned to Genzyme pursuant to this Section 
4.2(c) shall be offset against such credit. To the extent the amount credited 
to Nova Factor pursuant to this paragraph exceeds the amount owed by Nova 
Factor to Genzyme at such time, such excess shall be promptly paid by Genzyme 
to Nova Factor.

               (e)   Survival of Obligations. Termination of this Agreement 
shall not relieve either party from any liability or obligation it had 
incurred prior to the date of such termination including, but not limited to, 
obligations to pay any outstanding unpaid amounts due pursuant to this 
Agreement and to accept returns of Cerezyme-TM- in accordance with the 
provisions of this Agreement. It is the express intention and agreement of 
the parties hereto that all the covenants, agreements, warranties and 
indemnities contained in Sections 4.1, 4.5 and 4.7 shall survive the 
termination of this Agreement.

         4.3   Force Majeure. Neither party shall be liable to the other for 
failure or delay in the performance of any of its obligations under this 
Agreement for the time, and to the extent, such failure or delay is caused by 
riots, civil commotion, wars, hostilities between nations, embargoes, acts of 
God, earthquakes, storms, fires, strikes, sabotage, explosions, shortages of 
raw materials or power, or

                                       22
<PAGE>

any other matter which is beyond the reasonable efforts of the party to 
control. This provision shall not excuse, or apply to, obligations of a party

violate the restrictions st out in Section 4.5 hereof, or interfere with the

contained herein and for other good and valuable consideration, the receipt 
and adequacy of which are hereby acknowledged, the parties hereto agree as 
follows:

                     
                                  ARTICLE I
                               Distributorship

         1.1   Appointment. Genzyme hereby appoints (1) PTI, for the period 
commencing on April 1, 1994 and ending on June 30, 1994, to act as a 
preferred distributor of Ceredase -Registered Trademark- enzyme in all the

1994, to act as a preferred distributor of Ceredase -Registered Trademark- 
enzyme in all the states of the United States (each of PTI and Nova Factor, 
during the period that the foregoing appointment is in effect with respect to

Distributor hereby accepts such appointment. During the period of time that 
this Agreement is in effect, the Distributor shall sell Ceredase -Registered 
Trademark- enzyme to third parties, and perform the other obligations set out 
herein.

         1.2   Territory. Subject to the rights of Genzyme under this Section 
1.2, the Distributor shall be a distributor of Ceredase -Registered 
Trademark- enzyme in all the states of the United States. The parties further 
agree and acknowledge that (1) Genzyme may distribute Ceredase -Registered

         1.3   Terms Applicable to Distributorship. The Distributor shall 
have sole responsibility and authority for determining the price at which it 
will resell Ceredase -Registered Trademark- enzyme to its customers. Genzyme 
shall not be involved in that determination in any way. In the event that the 
Distributor determines to sell Ceredase -Registered Trademark- enzyme at the 
price per unit at which it buys Ceredase -Registered Trademark- enzyme from 
Genzyme, the distributorship shall be subject to the terms and conditions set 
forth in Article III of this Agreement. In the event PTI determines to sell 
Ceredase -Registered Trademark- enzyme at a price other than the price per 
unit at which it buys Ceredase -Registered Trademark- enzyme from Genzyme, 
the purchase and sale of Ceredase -Registered Trademark- enzyme shall be 
conducted in the manner set forth in Article II of this Agreement. At or 
prior to the time of execution of this Agreement, the Distributor shall make

         1.4   Applicability of Unamended Distribution Agreement. The terms 
and conditions of the Unamended Distribution Agreement (subject, however, to

Distributor's Warehouse (as defined below) prior to or on October 31, 1992, 
all accounts receivable generated from sales of Ceredase -Registered 
Trademark- enzyme prior to November 1, 1992, and all accounts receivable 
generated from the sale of the inventory of Ceredase -Registered Trademark- 
enzyme located at the Distributor's Warehouse on or prior to October 31, 1992.

         1.5   Applicability of Amended Distribution Agreement. The terms and 
conditions of the Amended Distribution Agreement shall govern all

govern the sales of Ceredase -Registered Trademark- enzyme by the Distributor.

virtue of the Assignment, Nova Factor, to Genzyme under the Unamended 
Distribution Agreement and that the Amended and Restated Security Agreement 
secures the obligations of PTI and, by virtue of the Assignment, Nova Factor, 
to Genzyme under the Amended Distribution Agreement. In addition to the

          3.2   Purchase and Maintenance of Inventory of Ceredase-Registered 
                Trademark- Enzyme.
          
          (a)   Sale of Ceredase-Registered Trademark- Enzyme. The 
Distributor shall order Ceredase-Registered Trademark- from Genzyme, and 
Genzyme shall sell Ceredase-Registered Trademark- enzyme to the Distributor. 
Genzyme shall at its cost ship each order of Ceredase-Registered Trademark-

such calendar quarter, however, in no event will such purchase cause the 
inventory to exceed an average of * days for such calendar quarter; provided 
further that in no event shall the Distributor be required to have inventory 
of Ceredase-Registered Trademark- enzyme on hand in excess of *

Genzyme. The service fees earned by the Distributor for any 
Ceredase-Registered Trademark- enzyme returned to Genzyme pursuant to this 
Section 3.2(b) shall be credited against future service fees earned by the 
Distributor, or Genzyme may request that the Distributor reimburse it for

enzyme that is returned, as Genzyme may elect. The Distributor agrees to use 
the shortest dated Ceredase-Registered Trademark- enzyme first. The 
Distributor shall provide Genzyme weekly reports on inventory levels, which

shall be unused upon termination of the Distributor's election to be subject 
to Article III, the excess of the prepaid amounts over the amounts actually 
due to Genzyme shall be immediately returned to the Distributor.

(a "Patient)", physician, clinic or hospital (any of a Patient, physician, 
clinic or hospital may hereafter be referred to as a "Ceredase-Registered 
Trademark- Enzyme Customer"). Genzyme shall, at its cost, insure all 
Ceredase-Registered Trademark- enzyme against loss from the time of shipment 
until delivery to the Distributor. The Distributor shall, at its cost, insure 
all Ceredase-Registered Trademark- enzyme in its possession until the 
delivery of Ceredase-Registered Trademark- enzyme to a Ceredase-Registered 
Trademark- Enzyme Customer for its replacement (i.e., market) value against 
fire, theft, loss or destruction, and such other risks as are customarily 
insured against by prudent persons in a similar line of business, with an 
insurance carrier qualified to do business (in the State of Tennessee or such 
other place as Genzyme may authorize.) The Distributor shall provide Genzyme 
with certificates of such

                                       13

insurance prior to the Distributor's election to be subject to the terms of 
Article III.

materials as shall be deemed necessary by Genzyme to adequately promote and 
market Ceredase-Registered Trademark- enzyme. The Distributor shall have no 
responsibility for undertaking any sales efforts in connection with 
Ceredase-Registered Trademark- enzyme and all inquiries received by the 
Distributor concerning potential sales or prescriptions of 
Ceredase-Registered Trademark- enzyme shall be referred to Genzyme by the 
Distributor.

          3.5   Designation of Patients and Recipients.

          (a)   Patient Status. The Distributor shall sell 
Ceredase-Registered Trademark- enzyme under this Article III only to a 
Patient previously approved by Genzyme (an "Approved Patient") or to a 
physician, hospital or clinic for administration to an Approved Patient. If 
sale is made to an Approved Patient, shipment may nonetheless be made to a 
physician, hospital or clinic, which will dispense Ceredase-Registered 
Trademark- enzyme to the Approved Patient. Before approving the initial 
shipment to, or on behalf of, a Patient, Genzyme shall make such inquiries as 
Genzyme, in its sole discretion, deems appropriate to determine whether 
Ceredase-Registered Trademark- enzyme is indicated for such Patient, which 
inquiries shall include obtaining a letter or summary of medical necessity 
signed by Patient's physician where required by the third party payor and 
determining the availability of insurance or other source for payment for 
Ceredase-Registered Trademark- enzyme.

          (b)   Patient Tracking System. The Distributor shall establish a 
patient tracking system in a mutually acceptable format that tracks the dose,

Trademark- enzyme, and to permit the Distributor to file claims with a third 
party payor, if any, or to submit invoices to the appropriate 
Ceredase-Registered Trademark- Enzyme Customer.

          3.6   Distribution and Pharmacy Services.

          (a)   Physician Authorization. Following the inquiry provided for

shall obtain:

                (i)   a prescription which is either (A) in proper form 
signed by the Approved Patient's physician, which physician shall be duly 
licensed to practice medicine and dispense drugs in accordance with 
applicable state and federal law, or (B) communicated verbally by said 
physician if such communication is valid under applicable state law; or       

          (ii)  an authorized purchase order from an entity, such as a clinic 
or hospital, authorized under applicable state law to dispense drugs to the 
Approved Patient(s).

          In the event that shipment of Ceredase-Registered Trademark- enzyme 
is to be made to a Ceredase-Registered Trademark- Enzyme Customer who wishes

          sufficient amounts of Ceredase-Registered Trademark- enzyme to a 
physician, hospital or clinic to permit dispensing of single or multiple

prior authorization of Genzyme.

          (c)   Pharmacy Records. The Distributor shall maintain such 
pharmacy records as are required by applicable federal and state law, 
regulations and orders. Such records shall remain the property of the

with the Approved Patient's third party payor, if any, the necessary billing 
forms and billing procedures, including billing address, required to file any 
claim for the Ceredase-Registered Trademark- enzyme on the Distributor's or 
such Approved Patient's behalf, or, in the event the Distributor is acting as 
billing agent for a Ceredase-Registered Trademark- Enzyme Customer pursuant 
to an executed Sales Agreement, for such Ceredase-Registered Trademark- Enzyme 
Customer and (ii) make due inquiry whether it may lawfully dispense 
Ceredase-Registered Trademark- enzyme in the state to which shipment has been 
directed.

          (b)   Inventory Availability. The Distributor shall be required to 
ship Ceredase-Registered Trademark- enzyme only from Ceredase-Registered 
Trademark- enzyme inventory which Genzyme has previously delivered to the 
Distributor.

          (c)   Packaging. The Distributor shall pack Ceredase-Registered 
Trademark- enzyme in cold packs, cartons or other packaging with such 
insulation or other packing materials as required by the package insert or 
FDA-approved labeling, or as 

     
                                       16

otherwise agreed by the parties. The Distributor shall, at its cost, cause 
Ceredase-Registered Trademark- enzyme to be delivered to Ceredase-Registered 
Trademark- Enzyme Customers by common carrier, overnight courier or other 
similar method of shipment selected by the Distributor.

          (d)   Return of Ceredase-Registered Trademark- Enzyme. In the event 
that a shipment of Ceredase-Registered Trademark- enzyme is refused or 
rejected by the Ceredase-Registered Trademark- Enzyme Customer, the 
Distributor will cause the shipment of Ceredase-Registered Trademark- Enzyme 
to be returned to the Distributor's Warehouse at the Distributor's expense.

to a Ceredase-Registered Trademark- Enzyme Customer, the Distributor shall 
prepare and mail an invoice for such shipment within * (*) business days 
after receipt by the Distributor of the documentation necessary for billing 
to be provided by Genzyme under Section 3.5 of this Agreement and thereafter 
to any third party payor. Each invoice, as appropriate, shall be on a form 
agreed to by the parties or upon the standardized form (such as HCFA - 1500 - 
Health Insurance Claim Form) required by a third party payor or in such 
electronic billing format as may be required. In the event 
Ceredase-Registered Trademark- enzyme is dispensed to an Approved Patient, 
the Distributor shall submit the invoice to the Approved Patient or, if 
authorized to do so, to the applicable third party payor. If the Distributor 
has shipped Ceredase-Registered Trademark- enzyme to a Ceredase-Registered 
Trademark- Enzyme Customer which is not an Approved Patient, the Distributor 
shall submit the invoice to the Ceredase-Registered Trademark- Enzyme 
Customer (except a Ceredase-Registered Trademark- Enzyme Customer for which 
the Distributor acts as a billing agent). If the Distributor has shipped 
Ceredase-Registered Trademark-

Distributor under this Article III.

          3.11   Accounting and Financial Reporting. The Distributor shall 
maintain records and books of account, in the form of computer data or 
otherwise, which will identify the Distributor's inventory of 
Ceredase-Registered Trademark- enzyme, each sale and shipment of 
Ceredase-Registered Trademark- enzyme by the Distributor (showing recipient's 
name, amount of drug dispensed, and charges for said drug), and all revenue 
collected from the sale and distribution of Ceredase-Registered Trademark-

            (ii)  Genzyme shall assume responsibility for and shall indemnify

      4.2   Term, Renewal and Termination.

      (a)   Term. This Agreement shall be for an initial term of three years 
from the date of execution, unless otherwise terminated in accordance with 
this section. Unless otherwise terminated, this Agreement will automatically 
renew at the expiration of the initial three-year term for an additional 
period of one year and shall thereafter automatically renew from year to year

      (b)   Termination. This Agreement shall automatically terminate upon 
(i) the mutual agreement of Genzyme and the Distributor, (ii) at any time

may given written notice of the 

                                     26


<PAGE>

breach to the breaching party, and if said breach is not cured within 30 days 
following the giving of said notice, this Agreement shall at the option of 
the nonbreaching party be terminated. Late payment by the Distributor under 
the terms of Section 3.2(c) shall not constitute a breach of the terms of 
this Agreement sufficient to give rise to termination of this Agreement.

      (c)   Return of Ceredase-Registered trademark- Enzyme. The Distributor 
shall cause the inventory of Ceredase-Registered trademark- enzyme then in

Distributor shall bear the risk of loss in accordance with Section 3.3(d).

      (d)   Survival of Obligations. Termination of this Agreement shall not 
relieve either Genzyme or the Distributor from any liability or obligation it 
had incurred prior to the date of such termination including, but not limited

      4.3   Force Majeure. Neither Genzyme nor the Distributor shall be 
liable to the other for failure or delay in the performance of any of its 
obligations under this Agreement for the time, and to the extent, such 
failure or delay is caused by riots, civil commotion, wars, hostilities 
between nations, embargoes, acts of God, earthquakes, storms, fires, strikes, 
sabotage, explosions, shortages of raw materials or power, or any other 
matter which is


                                  27

beyond the reasonable efforts of the party to control. This provision shall 
not excuse, or apply to, obligations of a party to make monetary payments

by litigation discovery requests, subpoena, civil investigative demands or 
similar processes to disclose such information, nor shall it prohibit 
disclosure and use by PTI or Nova Factor or such information, if and as 
necessary in any litigation between PTI or Nova Factor and Genzyme. PTI shall 
continue to be bound by the terms of this Section 4.5, and by any comparable

      4.10 Specific Performance. Each of the parties hereto acknowledges that 
violation of Section 4.5 and 4.7 could cause irreparable damage to the party

event of a breach or threatened breach of any of these sections, the party 
alleging such breach shall be entitled to injunctive relief prohibiting such 
breach or threatened breach in any court of appropriate jurisdiction of the 
United States or of any state or other political subdivision thereof.

performance of certain of its obligations under this Agreement by a third 
party pursuant to an agreement between the Distributor and such third party.  
The Distributor shall not enter into such agreement without the prior written 
consent of Genzyme, which shall not be unreasonably withheld, provided that

2.   APPOINTMENT AS PREFERRED DISTRIBUTOR

2.1  Subject to the terms and conditions contained in this Agreement, Biogen 
     hereby appoints Nova Factor and Nova Factor hereby accepts appointment 
     as a nonexclusive, preferred distributor of Product to Home Delivery
     Customers. Nova Factor shall not sell Product other than to Home Delivery
     Customers without the prior written consent of Biogen. Biogen expressly
     reserves the right to appoint other distributors, to sell Product to 
     wholesalers, pharmacy benefit managers and other third parties and to 
     sell Product directly. Biogen shall provide Nova Factor with written 
     notice at least thirty (30) days prior to the effective date of any 
     agreement between Biogen and a third party under which Biogen grants the 
     third party the right to sell Product to Home Delivery Customers which 
     such notice shall specify the name of the third party.

3.   ORDERS, DELIVERY, FORECASTS

3.1  The parties hereto agree that, commencing upon Commercial Launch and 
     continuing during the term of this Agreement, Nova Factor shall purchase 
     Product from Biogen at the prices set forth in Section 8, and, subject 
     to the right of Biogen to allocate supplies of Product under Section 3.6,
     Biogen shall supply Product to Nova Factor, for sale and distribution to
     Home Delivery Customers. Nova Factor shall order Product from Biogen in 
     such quantities as are necessary to meet the demand for Product from 
     Nova Factor's Home Delivery Customers. On average during any month, Nova 
     Factor shall submit orders not more frequently than once per week. All 
     orders shall be firm and Nova Factor shall not change or cancel an order 
     without prior approval from Biogen. All purchases of Product by Nova 
     Factor shall be on the terms and conditions set forth in this Agreement.
     No purchase order, invoice or other form shall be deemed to vary the 
     terms of this Agreement. To assist Biogen in managing its manufacturing 
     operations, Nova Factor shall furnish to Biogen, on the first day of each
     month, a nonbinding forecast of Nova Factor's anticipated needs for 
     Product for such month and the following five months. Biogen shall assist
     Nova Factor in preparing forecasts for the first three months after 
     Commercial Launch. Each forecast shall represent Nova Factor's good faith
     best estimate of its Product needs. Notwithstanding anything herein to 
     the contrary, if Biogen receives an order in any month which would cause 
     the total amount ordered for such month to exceed the amount shown on 
     the first forecast for such month, Biogen shall have the right, in its 
     sole discretion, to reject the order. As soon as Nova Factor's inventory
     falls to a one-week supply of Product, Nova Factor shall submit an order 
     to Biogen for an additional two (2) weeks' supply of Product, based on 
     Nova Factor's most recent forecast. Biogen shall notify Nova Factor of 
     receipt from the FDA of approval to manufacture Product at Biogen's 
     Cambridge facility and of approval to market and sell Product in the 
     Territory and of the date of Commercial Launch.

3.2  Biogen shall ship Product to Nova Factor not more frequently than weekly 
     FOB Biogen's warehouse facility. Biogen shall ship Product to Nova 
     Factor by means of transportation




                                       3



<PAGE>


     (commercial truck or better) determined by Biogen and at Biogen's cost. 
     While Biogen shall use reasonable efforts to avoid any delay in 
     delivering Product on the delivery dates agreed upon by the parties, 
     failure to deliver Product by the agreed upon date will not be sufficient
     cause for termination of this Agreement by Nova Factor as long as the 
     delay does not extend beyond two (2) weeks from the agreed upon delivery
     date, nor will Biogen be liable to Nova Factor for late delivery.

3.3  Nova Factor shall unload each shipment of Product immediately upon 
     receipt from Biogen in accordance with the applicable SOP. The parties 
     acknowledge that preparation of the SOPs will continue after execution 
     of this Agreement and Biogen and Nova Factor shall each use reasonable 
     efforts and shall each cooperate with the other to develop a set of 
     mutually agreeable SOPs within three (3) months after execution of this 
     Agreement. Nova Factor shall store Product in a refrigerated storage 
     area at the Facility. Nova Factor shall notify Biogen prior to moving 
     Product to another location for storage and distribution. Nova Factor 
     shall use storage facilities and storage conditions for Product which 
     comply with applicable SOPs. Nova Factor shall at all times handle and 
     store Product in accordance with applicable SOPs. Nova Factor shall not 
     alter Product packaging without Biogen's consent (except to remove 
     Product from the shipping containers) and shall not alter Product 
     labeling except to add a prescription label to Product. Nova Factor 
     shall at all times comply with the information and recommendations 
     communicated by Biogen in writing with respect to the storage, handling 
     and shipment of Products, provided that if such information and 
     recommendations are materially different than those included in the SOPs 
     or otherwise set forth in this Agreement and result in a material 
     increase in the costs incurred by Nova Factor in performing its 
     obligations under this Agreement, the parties shall negotiate in good 
     faith *. Nova Factor shall be responsible for all costs associated with 
     storage, handling and shipment from the Facility of Product.

3.4  Nova Factor shall carefully examine Products upon delivery and shall 
     notify Biogen within one (1) business day of any nondelivery of a 
     portion of a shipment or any defect in any Product which is reasonably 
     discoverable upon visual inspection of the Product without unloading 
     individual shipping units. Along with notice of any defect, Nova Factor 
     shall furnish to Biogen a detailed description of the nature of the 
     defect. Upon receipt of notice of any defect or nondelivery, Biogen, at 
     its option, shall replace or repair any defective Product or issue Nova 
     Factor a credit in the amount of the purchase price paid for any 
     defective Product or replace or issue Nova Factor a credit in the amount 
     of purchase price paid for any undelivered Product. Except as set forth 
     in Section 16, the preceding sentence sets forth Biogen's sole liability 
     with respect to Product defects reasonably discoverable upon visual 
     inspection of the Product without unloading individual shipping units or 
     with respect to Product that is not in accordance with Nova Factor's 
     order and Section 9.1 sets forth Biogen's sole liability with respect to 
     other Product defects and Biogen shall not be otherwise liable to Nova 
     Factor. In the absence of written notice from Nova Factor to Biogen in 
     accordance with the terms of this Section 3.4, a shipment of Products 
     shall be deemed to have been delivered and accepted by Nova

  pursuant to Rule 406 under the Securities Act of 1933 and has been filed 
  separately with the Securities Exchange Commission.

     Factor as complete and in satisfactory condition. Nova Factor shall, at 
     Biogen's request and expense, follow Biogen's instructions to return to 
     Biogen or Biogen's third party disposal company any Products delivered 
     to Nova Factor which are not in compliance with the Specifications. Nova 
     Factor shall cooperate with Biogen in investigating the cause of any 
     defect in Product.

3.5  Title to Product shall transfer to Nova Factor upon delivery of Product 
     to the carrier for shipment to the Facility. Risk of loss of Product 
     shall transfer to Nova Factor upon delivery of Product to the Facility.

3.6  Notwithstanding anything herein to the contrary, in the event of a 
     shortage of Product, Biogen reserves the right to allocate available 
     supplies of Product in its sole discretion. If Biogen is not able to 
     supply Product to Nova Factor in the quantities ordered by Nova Factor 
     for more than twelve (12) weeks on any occasion during the term of this 
     Agreement because of a Product shortage, Nova Factor shall have the right
     to terminate this Agreement for material breach under Section 14.3 
     excluding the thirty (30) day cure period.

4.   CUSTOMER ORDERS AND HOME DELIVERY

4.1  Marketing and sales literature distributed by Biogen's sales force will 
     contain a Biogen toll-free number as the point of contact for all
     potential customers for Product. Biogen's customer service 
     representatives shall include Nova Factor in their description to 
     potential customers of various purchase and delivery options for 
     Product, and, if a potential customer expresses interest in Nova 
     Factor's home delivery program, the Biogen customer service 
     representative shall forward the call or direct the customer to Nova 
     Factor. Biogen and Nova Factor shall mutually agree on the description 
     of Nova Factor to be used by Biogen's customer service representatives. 
     Biogen shall provide Nova Factor with a copy of the script used by 
     Biogen's customer service representatives in describing Product 
     distribution options to potential customers. Nova Factor shall maintain 
     a telephone line dedicated to calls transferred from Biogen and to calls 
     from customers for Product. Nova Factor shall answer all calls from 
     customers for Product in accordance with a script mutually agreeable to 
     Biogen and Nova Factor. If the customer has volunteered information to 
     Biogen or has previously been in contact with Biogen's third party 
     reimbursement agency, Biogen or the agency shall transmit the 
     information to Nova Factor. At Biogen's request, Nova Factor shall 
     assist Biogen in developing a standard intake form for initial customer 
     contact. Nova Factor shall direct to Biogen's customer service operation 
     all potential users of Product who contact Nova Factor directly in 
     accordance with a script mutually agreeable to Biogen and Nova Factor.

4.2  Nova Factor shall ship Product to customers at their homes or to any 
     other residence, office or similar location designated by customer, not 
     including pharmacies, via Federal Express standard overnight delivery 
     service or another mutually agreed to overnight carrier. Nova Factor 
     shall package Products for shipment in insulated shipping units in


                                       5


<PAGE>

     accordance with the applicable SOP. Nova Factor shall use its best 
     efforts to ship Products such that Product having the earliest 
     expiration date is shipped first from available inventory. Nova Factor 
     shall track each shipment of Product to customer and confirm receipt. If 
     product is not received by the intended customer, Nova Factor shall use 
     reasonable efforts to track the missing shipment until found and, if 
     found, shall retrieve the missing shipment. Any shipment not delivered 
     to the intended recipient which is found shall be retrieved by Nova 
     Factor and, if determined by Nova Factor to be unusable, shall be 
     disposed of by Nova Factor.

4.3  Except for initial shipments made to a customer's home or designated 
     location and except where the customer's payor requires preapproval of 
     subsequent shipments. Nova Factor shall, subject to Product 
     availability, ship Product to a customer within 48 hours of receipt of 
     an order. Nova Factor shall use reasonable efforts to obtain 
     reimbursement clearance, if necessary, for anticipated subsequent orders 
     from a customer prior to actual receipt of the subsequent order. Nova 
     Factor shall ship each initial order and any subsequent order which 
     requires reimbursement clearance to a customer's home or designated 
     location within 48 hours of reimbursement clearance unless Biogen and 
     Nova Factor have agreed upon a first shipment program. At Biogen's 
     request, Biogen and Nova Factor shall work together to develop a first 
     shipment program to allow shipment of initial quantities of Product to a 
     patient prior to reimbursement clearance. If the parties have agreed 
     upon a first shipment program, Nova Factor shall comply with the 
     timelines for delivery of Product contained in the program.

4.4  Nova Factor shall be responsible for all billing and collection in 
     connection with its sales of Product. Nova Factor shall not bundle sales 
     of Product with other products or services, provided that Nova Factor 
     may list Product on the same invoice with other products for the same 
     customer, if required by the customer's insurance provider, as long as 
     the Product price and any negotiated discount from or allowance taken 
     with respect to the Product price are listed separately. Nova Factor may 
     bundle shipments of Product with other products for delivery to the same 
     customer, provided that such bundling is covered by an SOP.

4.5  Nova Factor shall be responsible for all costs associated with 
     distribution and delivery of Products to its customers.

5.   REIMBURSEMENT-RELATED SERVICES

5.1  To ensure a consistent, high level of services and to maintain 
     consistency of communications with end-users of Product, the parties 
     have agreed that Nova Factor will, as part of its commitment to its 
     customers, provide the following services for each potential or existing 
     Nova Factor customer who contacts Nova Factor for home delivery of 
     Product:


                                       6

<PAGE>


     (i)     Nova Factor shall collect the relevant insurance information 
             from each new customer who has insurance and shall obtain 
             confirmation of the existence and extent of insurance coverage 
             for Product from the customer's insurance provider or other 
             third party payor. Nova Factor shall use its best efforts to 
             confirm reimbursement coverage within one (1) week of receipt of 
             an order from a customer. Biogen understands that, despite Nova 
             Factor's best efforts, confirmation of reimbursement coverage 
             will often take longer than one (1) week.

     (ii)    Nova Factor shall accept assignment of benefits from each 
             customer with reimbursement coverage unless the customer's 
             insurance provider or other third party payor does not allow 
             assignment of benefits. To effect the assignment of benefits, 
             Nova Factor shall, within two (2) business days of initial 
             contact with each customer, provide to the customer the 
             applicable forms and instructions for assignment of benefits and 
             shall file the forms with the customer's insurance provider or 
             other third party payor at the time of Product shipment and 
             billing.

     (iii)   Upon receipt of the appropriate approval, Nova Factor shall bill 
             and submit the appropriate claims to each customer's insurance 
             provider, third party payor or other responsible party, 
             including Medicaid, but not including Medicare.

     (iv)    Consistent with applicable law and Nova Factor's standard 
             collection policy, a copy of which is attached hereto as 
             Schedule C (the "Nova Factor Collection Policy"). Nova Factor 
             shall use its best efforts to collect the amount allowed from 
             each customer's insurance provider or other third party payor, 
             and shall work with customers and negotiate with providers and 
             third party payors to maximize reimbursement coverage.

     (v)     Nova Factor shall bill patient co-payments, self-pays or 
             deductibles and shall use reasonable good faith efforts to 
             collect such payments consistent with applicable law and the 
             Nova Factor Collection Policy. Nova Factor shall provide Biogen 
             with a copy of any changes to the Nova Factor Collection Policy 
             prior to implementation of such changes.

     (vi)    Nova Factor shall make the intake coordinator function available 
             from 9:00 a.m. to 8:00 p.m., E.S.T, Monday through Friday, 
             except Nova Factor holidays, to answer customer, insurance 
             provider, third party payor and prescriber reimbursement 
             questions. Biogen will, in its sales and marketing material, 
             list Biogen's toll-free number as the number for users of the 
             Product to call with reimbursement questions. When Biogen 
             receives a telephone call from a Nova Factor customer with a 
             reimbursement question, the Biogen customer service 
             representative will transfer the telephone call to Nova Factor.

     (vii)   Nova Factor shall use its best efforts to resolve reimbursement 
             issues of customers who would like to purchase Product from Nova 
             Factor. If Biogen has engaged


                                       7


<PAGE>

             a third party to provide reimbursement support services to 
             Biogen, Nova Factor shall direct certain reimbursement inquiries 
             to such third party and share relevant information with such 
             third party, as specified in guidelines established by Biogen.

     (viii)  Biogen shall furnish to Nova Factor the criteria for 
             eligibility in Biogen's financial assistance program, and Nova 
             Factor shall direct potential customers who meet the criteria to 
             Biogen's customer service department.

5.2  Nova Factor shall not deny Product to customers who do not have insurance
     or who have insufficient insurance coverage if the customer has the
     ability to self-pay.

5.3  Nova Factor shall be responsible for all costs associated with the 
     services provided under this Section 5.

5.4  Nova Factor shall be responsible for assuring that the services provided 
     under this Section are carried out in a manner consistent with 
     applicable federal and state laws.

     p.m. E.S.T., Monday through Friday, except Nova Factor holidays, for

     new supply of Product.

6.3  Upon receipt of an order from a new customer, Nova Factor shall inquire 
     whether the customer has received Product administration training. If 
     the customer has not received Product administration training or would

     patient to Biogen's customer service department or such other contact as 
     Biogen shall designate.

6.4  Nova Factor shall maintain an inventory of Product educational materials 
     developed and provided by Biogen. Nova Factor shall, to the extent

      service representatives shall call each new customer one to three weeks

9.1   In the event Nova Factor or a Nova Factor customer returns or requests 
      to return a Product, Nova Factor shall promptly notify Biogen and 
      Biogen shall, upon return of Product, unless the customer requests 
      replacement Product, give Nova Factor a credit in the amount of the 
      purchase price paid by Nova Factor for the returned Product, provided 
      that the Product is returnable and returned under Biogen's then current 
      Return Goods Policy, a copy of which Biogen shall furnish to Nova 
      Factor, and provided that the reason for the return of the Product does 
      not arise from (i) the negligence or intentional misconduct of Nova 
      Factor or any of its agents or employees, (ii) failure of Nova Factor 
      to follow applicable SOPs or to otherwise comply with the terms  of 
      this Agreement or (iii) misdelivery or loss of Product by a carrier 
      used by Nova Factor. For any return of Product authorized by Biogen,

      the Product, to Biogen or Biogen's designated disposal company as 
      specified and in the manner described in the then current Return Goods

      determines not to supply replacement Product at no charge, Nova Factor 
      may purchase the replacement Product at the prices and on the terms set 
      forth in Section 8. Biogen shall not supply replacement Product to Nova 
      Factor at no charge if the need for replacement product arises from (i)

      agents or employees, (ii) failure of Nova Factor to follow applicable 
      SOPs or to otherwise  comply with the terms of this Agreement or (iii) 
      misdelivery or loss of Product by a carrier used by Nova Factor. Biogen 
      may change its Return Goods Policy in its sole discretion, provided

         regarding the cost of providing services to Biogen and the 
         information in the Database,and anything derived therefrom, 
         (collectively, the "Biogen Information") as the confidential and 
         exclusive property of Biogen, (except for the information in the 
         Database which shall be joint property of Biogen and Nova Factor), 
         and agrees not to disclose any of the Biogen Information to any 
         third party without first obtaining the written consent of Biogen. 
         Nova Factor agrees that it will use any Biogen Information only for 
         purposes of performing its obligations hereunder and for no other 
         purpose without the prior written consent of Biogen. Nova Factor 
         further agrees to take all practicable steps to ensure that the 
         Biogen Information will not be used by its directors, officers or 
         employees, except on like terms of confidentiality as aforesaid, and 
         will be kept confidential by them.

         The above provisions of confidentiality shall not apply to that part 
         of the Biogen Information which Nova Factor is able to demonstrate 
         by documentary evidence:

         (a)   was in Nova Factor's possession prior to receipt from Biogen; 
               or

         (b)   was in the public domain at the time of receipt from Biogen; or

         derived therefrom, (collectively, the "Nova Factor Information") as 
         the confidential and exclusive property of Nova Factor, and Biogen 
         agrees not to disclose any of the Nova Factor Information to any 
         third party without first obtaining the written consent of Nova 
         Factor, provided that Biogen may disclose Nova Factor Information to 
         any third party providing reimbursement-related services to Biogen 
         as long as the third party is obligated to Nova Factor to keep such 
         information confidential. Biogen agrees that it will use any Nova 
         Factor Information only for purposes of activities contemplated 
         hereunder and for no other purpose without the prior written consent 
         of Nova Factor. Biogen further agrees to take all practicable steps 
         to ensure that the Nova Factor Information will not be used by its 
         directors, officers or employees, except on like terms of 
         confidentiality as aforesaid, and will be kept confidential by them.

         The above provisions of confidentiality shall not apply to that part 
         of the Nova Factor Information which Biogen is able to demonstrate 
         by documentary evidence:

         
         (a)   was in Biogen's possession prior to receipt from Nova Factor;

               directors, officers or employees; or

               disclosing the information on behalf of Nova Factor and having a
               right of further disclosure; or

         (e)   is required by law to be disclosed.

         Biogen agrees that, at Nova Factor's request, it shall return to 
         Nova Factor all parts of the Nova Factor Information existing in 
         documentary form and will, at Nova Factor's request, return or

       reformation or deletion in which case this Agreement shall terminate.

22.9   Failure of either party to enforce a right under this Agreement shall

       this Agreement as a result of any subsequent default or breach.

22.10  This Agreement shall be construed and enforced in accordance with the

22.11  Unless waived by the parties, any dispute, controversy or claim 
       between the parties arising out of or relating to this Agreement 
       either during or after the term hereof (including the question as to 
       whether any particular matter is arbitrable) shall be solely and 
       finally settled by arbitration conducted in Memphis, Tennessee, if the 
       arbitration is initiated by Nova Factor or in the Boston, 
       Massachusetts metropolitan area, if the arbitration is initiated by 
       Biogen, in accordance with the Commercial Arbitration Rules of the 
       American Arbitration Association then in force (the "Rules"). The 
       party requesting arbitration shall serve upon the other party to the 
       controversy, dispute or claim a written demand for arbitration stating 
       the substance of the controversy, dispute or claim, the contention of 
       the party requesting arbitration, and the name and address of the 
       arbitrator appointed by it. The recipient of such demand shall within 
       twenty (20) days after such receipt appoint an arbitrator and notify 
       the party requesting arbitration of the identity of the arbitrator so 
       selected, and the two arbitrators shall appoint a third, and the 
       decision or award of any two arbitrators shall be final and binding 
       upon the parties. In the event that the two arbitrators fail to 
       appoint a third arbitrator within twenty (20) days of the appointment 
       of the second arbitrator, either arbitrator, or any party to the 
       arbitration, may apply to a judge of the United States District Court 
       for the district in which the arbitration is held for the appointment 
       of the third arbitrator and the appointment of such arbitrator by such 
       judge or such application shall have precisely the same force and 
       effect as if such arbitrator had been appointed by the two 
       arbitrators. If for any reason the third arbitrator cannot be 
       appointed in the manner prescribed by the preceding sentence, either 
       regularly appointed arbitrator, or either party to the arbitration, 
       may apply to the American Arbitration Association for appointment of 
       the third arbitrator in accordance with the Rules. If the parties upon 
       whom the demand for arbitration has been served fail or refuse to 
       appoint an arbitrator within twenty (20) days, the single arbitrator 
       shall have the right to decide alone, and such arbitrator's decision 
       or award shall be final and binding upon the parties. The decision of 
       the arbitrator shall be in writing and shall set forth the basis 
       therefor. The parties shall abide by all awards rendered in 
       arbitration proceedings, and all such awards may be enforced and 
       executed in any court having jurisdiction over the party against whom 
       enforcement of such award is sought. The party losing the dispute 
       which was submitted to arbitration shall pay the administrative 
       charges, arbitrator's fees, and related expenses of arbitration, and 
       each parties legal fees incurred in connection with any such 
       arbitration. This agreement to arbitrate shall be specifically 
       enforceable under the prevailing arbitration law.

WHEREAS, to reflect the additional services to be provided by Nova Factor, 
the parties desire to amend the Distribution Agreement as set forth herein;

     NOW THEREFORE, in consideration of the premises and mutual covenants

1.   Section 9 of the Distribution Agreement shall be amended to be and read

     "9.   REPLACEMENTS, RETURNS AND AVONEX-TM- ACCESS PROGRAM-TM

     9.1   In the event Nova Factor returns or requests to return a Product, 
           Nova Factor shall promptly notify Biogen and Biogen shall, upon 
           return of Product, unless the customer requests replacement 
           Product, give Nova Factor a credit in the amount of the purchase 
           price paid by Nova Factor for the returned Product, provided that 
           the Product is returnable and returned under Biogen's then current 
           Return Goods Policy, a copy of which Biogen shall furnish to Nova 
           Factor, and provided that the reason for the return of the Product 
           does not arise from (i) the negligence or intentional


<PAGE>

           misconduct of Nova Factor or any of its agents or employees, (ii) 
           failure of Nova Factor to follow applicable SOPs or to otherwise 
           comply with the terms of this Agreement or (iii) misdelivery or 
           loss of Product by a carrier used by Nova Factor. For any return 
           of Product authorized by Biogen, Nova Factor shall send the 
           Product, or shall instruct customers to send the Product, to 
           Biogen or Biogen's designated disposal company as specified and in 
           the manner described in the then current Return Goods Policy.

     9.2   Nova Factor shall refer any Nova Factor customer who requests 
           replacement Product to one of Biogen's customer support 
           specialists for authorization. Biogen's customer support 
           specialist shall authorize the supply of replacement Product at no 
           charge to a Nova Factor customer under appropriate circumstances 
           as determined by Biogen. Biogen shall not authorize the supply of 
           replacement Product to a Nova Factor customer at no charge if the 
           need for replacement product arises from (i) the negligence or 
           intentional misconduct of Nova Factor or any of its agents or 
           employees, (ii) failure of Nova Factor to follow applicable SOPs 
           or to otherwise comply with the terms of this Agreement or (iii) 
           misdelivery or loss of Product by a carrier used by Nova Factor. 
           If Biogen determines not to supply replacement Product to a Nova 
           Factor customer at no charge, Nova Factor may purchase replacement 
           product at the prices and on the terms set forth in Section 8.

     9.3   Biogen may change its Return Goods Policy in its sole discretion, 
           provided that if any change results in a material increase in the 
           costs incurred by Nova Factor in performing its obligations under 
           this Agreement, *.

     Components to end-users of Product (whether or not the end-users are Nova 
     Factor customers) who have requested Replacement Components and whose 
     requests have been approved by a Biogen customer support specialist. 
     Approval from a Biogen customer support specialist for Nova Factor to 
     supply Replacement Components shall be in the form of the transfer of the
     telephone call from the end-user on Biogen's customer support line to Nova
     Factor followed by same-day written confirmation from the Biogen customer

                                       2


<PAGE>
     user's physician within twenty-four (24) hours of the request. If Nova

     the request for Replacement Components or if Nova Factor otherwise 
     determines that the supply of Replacement Components to an end-user is not
     appropriate, Nova Factor shall notify a Biogen customer support specialist.

2.2  Nova Factor shall ship Replacement Components to end-users via 
     third-class mail unless the end-user requires an emergency supply in which
     case Nova Factor shall ship the Replacement Components via Federal Express
     standard overnight delivery service or another mutually agreed to
     overnight carrier (an "Emergency Shipment"). Nova Factor shall ship 
     Replacement Components within twenty-four (24) hours of receipt of the

     (24) hours of receipt of the applicable prescription. Nova Factor shall 
     package Replacement Components in accordance with industry standards, and

     Components are not received by the intended recipient, Nova Factor shall 
     use reasonable efforts to track and retrieve the missing shipment.

     supplies to end-users under this Section 2, at Nova Factor's cost. In 
     fulfilling its supply obligation under this Section 2, Nova Factor shall 
     use only those Replacement Components that conform to the Specifications. 
     Nova Factor shall perform appropriate quality control testing to confirm 
     that Replacement Components conform to Specifications, including but not 
     limited to (i) inspection of incoming inventory shipments to verify 
     conformance of Replacement Components to Specifications, (ii) documentation
     of such inspections and (iii) for each shipment to an end-user verification
     by a registered pharmacist or pharmacy technician acting under the direct 
     supervision of a registered pharmacist that the Replacement Components 
     being shipped are the Replacement Components that were requested and 
     authorized.

2.4  The parties agree that, notwithstanding anything herein to the contrary, 
     Section 9 of the Distribution Agreement, including the payment provisions
     of Section 9.7, shall no longer apply to the supply of replacement diluent,
     but rather replacement diluent shall be treated in the same manner as other
     Replacement Components under the terms of this Addendum.

     and shall notify a Biogen customer support specialist promptly in the event
     an Alliance Program Participant submits more than one voucher. Nova Factor

     contained in the Alliance Kits is required without having first obtained
     the necessary prescription. In the event Nova Factor determines that a 
     prescription

     Participant, Nova Factor shall use reasonable efforts to obtain a 
     prescription from the end-user's physician within twenty-four (24) hours of
     receipt of the voucher. If Nova Factor, having used reasonable efforts, is
     unable to obtain a prescription from an end-user's physician within five
     (5) business days of receipt of the voucher, Nova Factor shall notify a 
     Biogen customer support specialist.

3.2  Nova Factor shall ship Alliance Kits within two (2) business days of 
     receipt of the applicable voucher, unless Nova Factor determines that a 
     prescription is required in which case Nova Factor shall ship Alliance Kits
     within two (2) business days of receipt of the applicable prescription. 
     Nova Factor shall send Alliance Kits via third class mail, unless otherwise
     agreed by the parties. Nova Factor shall package Alliance Kits in 
     accordance with industry standards, and shall include on the Alliance Kit 
     a Nova Factor pharmacy label.

3.3  Nova Factor shall purchase the Replacement Components used in the 
     Alliance Kits and store the Alliance Kits, all at Nova Factor's cost. Prior
     to commencement of the Alliance Program by Biogen, Nova Factor shall have
     purchased *     of each Replacement Component contained in the Alliance Kit
     for use in the Alliance Kits (the "Initial Inventory"). At Nova Factor's
     request, in the event Nova Factor does not use the Initial Inventory by 
     December 31, 1997, Biogen shall repurchase the unused portion of the 
     Initial Inventory from Nova Factor, at a cost of $*    per repurchased 
     Alliance Kit. In fulfilling its supply obligation under this Section 3,
     Nova Factor shall use in the Alliance Kits only those Replacement 
     Components that conform to the Specifications. Nova Factor shall perform 
     appropriate quality control testing to confirm that Replacement Components
     contained in the Alliance Kits conform to Specifications, including but not
     limited to (i) inspection of incoming inventory shipments to verify 
     conformance of Replacement Components to Specifications, (ii) documentation
     of such inspections and (iii) for each shipment to an end-user verification
     by a registered pharmacist or a pharmacy technician acting under the direct
     supervision of a registered pharmacist that the Replacement Components 
     contained in the Alliance Kit are as specified under this Addendum.

2.    REIMBURSEMENT HOTLINE.
      ----------------------

      2.1    Hotline Services.  As additional services under the Distribution

             through which end-users, physicians, nurses, pharmacies, payors,

             the Reimbursement  Hotline shall include, but shall not be limited
             to, using reasonable efforts *

* Omitted information is the subject of a request for confidential treatment

                                         2
<PAGE>

             * If an end-user or other person referred to Nova Factor on the 
             Reimbursement Hotline has any questions related to Medicare 
             coverage for Product, Nova Factor shall, unless otherwise 
             specified by Biogen, transfer the person to the third party 
             service provider designated by Biogen to provide further 
             assistance on Medicare issues.

      2.2    Delivery Options.  In presenting the delivery options available 
             to an end-user referred to Nova Factor via the Reimbursement 
             Hotline, Nova Factor shall follow a script which accurately 
             describes all potential methods of delivery available to the 
             end-user and which is in a form mutually agreeable to Nova Factor
             and Biogen. If the end-user decides not to use Nova Factor's home
             delivery services for delivery of Product, Nova Factor shall use 
             reasonable efforts to obtain the name, telephone number and fax
             number of the desired dispensing pharmacy, and shall provide to 
             the dispensing pharmacy, by telephone or fax, all of the 
             information in Nova Factor's possession regarding the end-user.

      2.3    Staffing.   Nova Factor shall use qualified and properly trained 
             reimbursement specialists to answer calls on the Reimbursement 
             Hotline. The number of reimbursement specialists made available by
             Nova Factor to answer calls on the Reimbursement Hotline shall be
             determined by the volume of calls, and shall be that number which
             is sufficient to ensure a high level of customer service and 
             satisfaction. If Biogen believes that the number of reimbursement
             specialists made available by Nova Factor to answer calls on the 
             Reimbursement Hotline is not sufficient to ensure a high level of 
             customer service and satisfaction, Biogen shall notify Nova Factor
             and the parties shall meet to determine what corrective actions 
             Nova Factor shall take.

      2.4    Direct Delivery Customers.  Nothing in this Addendum or in the 
             operation of the Reimbursement Hotline shall be deemed to limit in 
             any way the obligation of Nova Factor to provide reimbursement-
             related services under the terms of Section 5 of the Distribution
             Agreement to those end-users who order Product from Nova Factor. 
             Services provided by Nova Factor to end-users under Section 5 of 
             the Distribution Agreement will not be considered Reimbursement 
             Hotline services for purposes of Section 7 of this Addendum.

      2.5    Customer Satisfaction Survey.   At Biogen's request from time to 
             time, Nova Factor shall, at no additional cost to Biogen, send 
             customer satisfaction surveys to Hotline Customers in a form 
             mutually agreed upon by the parties. The completed surveys shall 
             be sent to Biogen.

      2.6    Reliance on Payor Information.   Nova Factor shall have no 
             liability for relying upon information provided by third party 
             payors concerning coverage in the event that such information 
             shall subsequently prove to be incorrect, and Nova Factor may 
             include a disclaimer to that effect in any communication with 
             end-users or others regarding coverage by third party payors.

question being offered by the Partnership. However, if a Partner wishes to
provide therapies, services, supplies or goods of a type which is encompassed

and expenses of the Partnership shall be fifty percent (50%).

initial capital of the Partnership. Such contributions shall be made within a
reasonable period of time following execution of this Agreement as agreed upon
by the Partners.

of the business of the Partnership. All repayments shall be first applied
against interest due before reducing the principal balance of the loan.

or any of the Partners; and no such creditor or other person shall by reason of
any such foregoing provisions make any claim in respect of any debt, liability
or obligation (or otherwise) against the Partnership or any of the Partners.

Partnership without such competition constituting a breach of loyalty or other
duty owed by a Partner to the Partnership.

Committee. The presence of a quorum of the Steering Committee members shall be

the Steering Committee, approve in accordance with Section 7.02 hereof a budget

     7.04. Officers. The Steering Committee shall be authorized to appoint a
General Manager, and such other officers or agents of the Partnership, with such
titles and responsibilities, as the Steering Committee shall from time to time
designate in accordance with Section 7.01 hereof. To the extent that such duties
have not been contractually delegated to a third party, the Steering Committee
may authorize officers of the Partnership to exercise any of the powers or to
carry out any of the responsibilities of the Steering Committee set forth in
Section 7.01(b) hereof, provided, however, that the Steering Committee may not
delegate to any officer or officers of the Partnership the responsibility (i)
for making Partnership Major Decisions, or (ii) to carry out any of the
responsibilities of the Steering Committee described in Section 7.01(b)(x)

                                  ARTICLE VIII
                            OPERATIONS AND EMPLOYEES

                                     - 21 -

<PAGE>


     8.01. Operations. Notwithstanding the restriction that the Partnership
shall not enter into any separate agreement with either Partner without the
written consent of the Partner which is not a party to such agreement, both
Partners consent and agree that as needed the Partnership may contract with NF
or its parent, Southern Health Systems, Inc. ("SHS") for certain supplies,
equipment, solutions and other materials and for the performance of certain
services as may be needed and reasonably available from NF or SHS. Consent of
the Steering Committee shall be required for entering into these contracts.

     8.02. Employee Protection. During the term of this Agreement and for a
period of eighteen (18) months following termination of this Agreement, each
Partner agrees that neither it, nor any entity associated with it or under its
control will hire any employee of the Partnership who, immediately prior to
employment by the Partnership, was an employee of the other Partner (or its
corporate affiliates or subsidiaries). This limitation will be subject to waiver
based on written consent of both Partners.

     8.03. Proprietary Information. Each Partner is currently engaged in the
same business as the Partnership and each Partner has developed, or may develop
during the term hereof, certain formulas, products, methods of doing business,
customer lists and other proprietary information which the Partner deems to be

                                     - 22 -

<PAGE>


confidential and a trade secret. Some of these formulae, products, methods and
other proprietary information will be made available to the Partnership, and
thus become known to the other Partner. It is contemplated that each employee or
agent of the Partnership who will be exposed to such confidential information
will be required to execute a confidentiality agreement. Each Partner also
agrees that it will not duplicate, make use of, or disclose, in any manner
whatsoever, any information which is deemed to be confidential by the other
Partner, either during or after the term of this Agreement, without the express
prior written consent of the other Partner. Each Partner further agrees that it
will cause its employees and agents who will have access to such information to
execute a confidentiality agreement similar to that executed by employees and
agents of the Partnership.

     In the event that any information deemed to be confidential by a Partner is
provided to the Partnership or its employees or agents in writing, the Partner
providing same shall mark the writing as "confidential". In the event that such
information is provided in non-written form such as orally, by audio tape,
videotape or computer software or disc, the Partner claiming such information to
be confidential shall furnish to the other Partner and/or the Partnership's
employees and agents a written list containing a brief description of such item
and designating such item as confidential. Upon termination of this Agreement
all copies of any information hereunder deemed, or designated as, confidential
by a 

                                     - 23 -

<PAGE>



Partner shall be returned to the Partner who supplied the information, or who
designated same as confidential. Notwithstanding the preceding provisions the
following types of information provided by a Partner shall always be deemed
confidential whether or not so designated: Patient records; prescription files;
lists of patient names, addresses or phone numbers; lists of referring
practitioner names, addresses or phone numbers; costs of goods and supplies; and
financial records of the Partner.

     It is recognized and acknowledged that damages caused by a Partner's breach
of this Section would be difficult to ascertain and would not adequately
compensate the other Partner for its losses. Therefore, both Partners agree that
the Partner claiming a breach of this Section shall be entitled to injunctive
relief to restrain the commission or continued commission of said breach either
through the arbitration procedures set out herein or, at the injured Partner's
discretion, by seeking such relief from a court of competent jurisdiction.

     Notwithstanding the preceding paragraphs of this Section, this restriction
shall not apply to (i) any information which is not deemed confidential
hereunder, or which has not been designated as confidential in the manner
specified herein, (ii) any information which was known to a Partner prior to its
disclosure by the other Partner, (iii) any information which is or becomes
public knowledge 

                                     - 24 -

<PAGE>


through no failure of a party bound by this Agreement, or (iv) any information
which is independently developed by a party hereto.

     It is further contemplated that each Partner will execute a confidentiality
agreement with the Partnership by which, subject to Sections 11.04 and 14.01
herein, each will agree not to disclose during the term of the Partnership
confidential information developed by the Partnership.

                                   ARTICLE IX
                                   ACCOUNTING

     9.01. Fiscal Year. The fiscal year of the Partnership for purposes of
accounting and federal and local income and other taxes shall begin on January 1
and end on December 31 of each year of the term.

     9.02. Books and Records. The Steering Committee shall establish, maintain
and keep accurate, full and complete books of account and records (the
"Partnership Books") showing the assets and liabilities, revenues and
expenditures, and all other aspects of the operations, transactions and
financial condition of the Partnership (including changes in the respective
capital accounts of the Partners). The Partnership Books shall be maintained at
the principal office of the Partnership or at such other place reasonably
designated by the Steering Committee, and each Partner and its authorized
representatives shall have access to the 

                                     - 25 -

<PAGE>


Partnership Books during ordinary business hours. The Partnership Books shall be
maintained in accordance with generally accepted accounting principles,
consistently applied.

     9.03. Financial Reports. The Steering Committee shall cause to be prepared
and submitted to each Partner, within one hundred fifty (150) days after the end
of each fiscal year, unaudited financial statements for the fiscal year showing
the revenues and expenditures, and the assets and liabilities, of the
Partnership. In addition, the Steering Committee shall cause to be prepared and
submitted to each Partner, within thirty (30) days after the end of each month,
an unaudited financial statement for that month, showing the revenues and
expenditures, and the assets and liabilities, of the Partnership for such month.

     9.04. Bank Accounts. All receipts, funds and income of the Partnership
shall be deposited in an account or accounts in the name of the Partnership in
such bank or banks as shall be designated by the Steering Committee. All such
bank accounts shall be owned by both Partners, and the signatories for such bank
accounts shall be duly authorized representatives selected by both Partners,
together with such other persons as the Partners may jointly designate for
specific accounts. No check to one Partner shall be issued without the signature
of a representative of the other Partner. There shall be no commingling of the
monies and funds of the Partnership with monies and funds of any other entity,

                                     - 26 -

<PAGE>



and such monies and funds shall be maintained in separate and distinct accounts
of the Partnership.

     9.05. Tax Status and Tax Returns. Each of the Partners hereby recognizes
that, for United States federal income tax purposes, the Partnership will be
subject to all provisions of Subchapter K of Chapter 1 of Subtitle A of the
United States Internal Revenue Code of 1986, as amended. The Steering Committee
shall prepare the informational U.S. federal, state and municipal tax returns
required to be filed by the Partnership, and all other tax returns required to
be filed by the Partnership; provided, however, that the filing of U.S. federal,
state, municipal and other tax returns shall not be construed to extend the
purposes of the Partnership or expand the obligations or liabilities of the
Partners.

                                    ARTICLE X
                      RESTRICTIONS ON TRANSFER OF INTERESTS
                     IN PARTNERSHIP, RIGHT OF FIRST REFUSAL


     10.01. Restrictions on Transfer. During the term of this Agreement, neither
Partner may, directly or indirectly sell, transfer, assign, give, pledge,
syndicate, hypothecate, encumber, alienate or otherwise dispose of (voluntarily
or involuntarily, by operation of law or otherwise) all or any part of its
interest in the Partnership without the prior consent of the other Partner,
except that either Partner may transfer not less than all of its interest in the
Partnership (a) to a corporation which is wholly

                                     - 27 -

<PAGE>


owned by such Partner, or which acquires substantially all of the assets and
assumes substantially all of the liabilities of such Partner (including
specifically assuming in writing all of the Partner's obligations under this
Agreement) or (b) in the manner provided in Section 10.02 hereof. If a loan to
the Partnership from a Partner who desires to sell its Partnership interest
remains outstanding at the time of sale, all of the selling Partner's rights in
said loan must be sold as part of the selling Partner's Partnership interest.

     10.02. Right of First Refusal. This Section sets forth a procedure by which
a Partner may sell all of its interest in the Partnership, but does not
authorize a Partner to sell less than all of its interest in the Partnership
without the consent of the other Partner. In the event a Partner desires to sell
all (but not a part) of its interests in the Partnership, it shall first notify
and fully inform the other Partner in writing of the identity of the proposed
buyer ("Buyer") and the proposed terms and conditions of such proposed sale
("Notice of Proposed Sale") and shall afford the non-selling Partner the
opportunity, within thirty (30) days after receiving such notice, to elect to
purchase such interests in accordance with such proposed terms and conditions by
delivery of written notice to this effect to the selling Partner. In the event
the non-selling Partner shall so elect to make a purchase of such interests on
such terms and conditions, the closing on the purchase will take place according
to the proposed terms and conditions of 

                                     - 28 -

<PAGE>




the sale, or, if not specified, within a reasonable period (but not more than
ninety (90) days) after such election to purchase is made. In the event the
non-selling Partner does not so elect, within the 30 days period to purchase
such interests so offered, the selling Partner will then be free to sell to the
proposed Buyer all (but not part) of such interests on terms no less favorable
to the selling Partner than the proposed terms and conditions specified in the
Notice of Proposed Sale within a period of one hundred and twenty (120) days
after the end of such 30 day period. In the event that the sale does take place
to the proposed Buyer in compliance with this Section within the 120 day period,
the selling Partner shall give written notice to this effect to the non-selling
Partner no later than the date of the closing thereof. At any time following
receipt of the Notice of Proposed Sale and prior to expiration of 30 days
following the closing thereof, the nonselling Partner shall have the right (by
delivering notice to the selling Partner or to the Buyer (if the sale has
closed)) to terminate this Agreement. In the event a sale of such interests is
not made by the selling Partner to the proposed Buyer during such 120 day
period, any sale by that Partner of its interests in the Partnership will
require compliance anew with the provisions of this Section.

"Default"), and such Default shall continue for a period of at least forty-five
(45) days after written notice of such Default from the Non-Defaulting Partner
to the Defaulting Partner;

     (c) upon the permanent cessation or abandonment of the business of the
Partnership;

     (d) upon 12 months written notice of termination by either Partner;
provided, however, that neither Partner may request termination under this

become unable to pay or shall fail to pay generally its debts as such debts
become due, or shall admit in writing such inability or such failure to pay

purpose of, commencing (in the capacity of debtor) a voluntary case under any

otherwise;

     (g) upon election by the non-selling Partner pursuant to Section 10.02
hereof; or

     (h) upon expiration of this Agreement.

     11.02. Distributions on Partnership Termination.

     (a) Upon termination of the Partnership, the affairs of the Partnership
shall be wound up as soon as practicable. A reasonable time shall be allowed for
the liquidation mad discharge of the liabilities of the Partnership. Each
Partner shall be furnished with an audited financial statement, prepared by the
Partnership's Certified Public Accountants, setting forth the total amount of
assets and liabilities of the Partnership as of the date of complete
liquidation. In the event that the liabilities of the Partnership (including
loans to Partners shall exceed the assets available for distribution, the
Partners shall assume and pay the excess in accordance with their respective
Partnership Percentages, and in the event that any Partner (the "Delinquent
Partner") shall fail to pay its full share of any such excess and the other
Partner is required to do so, then the other Partner shall be entitled to
contribution from the Delinquent Partner to the extent of the Delinquent
Partner's obligation hereunder. During the period of the winding up of the
Partnership, the affairs of the Partnership shall continue to the extent
necessary to permit an orderly termination thereof.

     (b) The Partnership assets shall be used and distributed first to pay the
liabilities of the Partnership, including the complete satisfaction of all liens
against Partnership property

                                     - 32 -

<PAGE>



(other than the loans or advances that may have been made by the Partners to the
Partnership) and the expenses of liquidation. The remaining Partnership assets
shall next be applied to the repayment of any loans or advances made to the
Partnership by the partners. The net assets of the Partnership, after making all
of the payments previously set forth in this Section shall be distributed to the
Partners in an amount equal to their respective Partnership Percentage in the
Partnership. If assets other than cash are distributed, such assets shall be
valued at their then fair market value.

     (c) Distribution upon liquidation shall be in full and final satisfaction
of all amounts of capital contributed by the Partners pursuant to Section 4.02
and 4.03 hereof.

     11.03. Termination of Agreement. This Agreement shall terminate upon (i)
the termination of the Partnership in accordance with Section 11.01 hereof, and
(ii) the completion of the winding up of the affairs of the Partnership and the
distribution of all assets and payment of all liabilities of the Partnership in
accordance with Section 11.02 hereof.

     11.04. Post-Termination Business Activities of the Partners. The Partners
agree that upon termination of the Partnership, there will be a return to the
status guo ante; at such time, each Partner will be free to offer to Restricted
Patients the 

                                     - 33 -

<PAGE>



services and supplies formerly offered by the Partnership, subject to the
limitations set out in Sections 8.02, 8.03 and 14.01 herein. Upon termination of
the Partnership for any reason, the Partnership name shall not be used by either
Partner. The Partnership's telephone numbers shall not be used by either
Partner. Upon termination of this Agreement copies of all Partnership files and
lists of patients, other than information covered by the confidentiality

                                   ARBITRATION

     Except as otherwise provided in Section 8.03, any dispute, controversy or
claim between the Partners arising out of or relating to this Agreement either
during or after the term thereof (including the question as to whether any
particular matter is arbitrable) shall be solely and finally settled by
arbitration conducted in Dallas, Texas, in accordance with the Commercial
Arbitration Rules of the American Arbitration Association then in force (the
"Rules"). The Partner requesting arbitration shall serve upon the other Partner
to the controversy, dispute or claim a written demand for arbitration, stating
the substance of the controversy, dispute or claim, the contention of the
Partner requesting arbitration, and the name and address of the arbitrator

                                     - 34 -

<PAGE>



appointed by it. The recipient of such demand shall within 20 days after such
receipt appoint an arbitrator and notify the other Partner of the identity of
the arbitrator so selected, and the two arbitrators shall appoint a third, and
the decision or award of any two arbitrators shall be final and binding upon the
parties. In the event that the two arbitrators fail to appoint a third
arbitrator within 20 days of the appointment of the second arbitrator, either
arbitrator, or either party to the arbitration, may apply to a judge of the
United States District Court located in or nearest to Dallas, Texas for the
appointment of the third arbitrator, and the appointment of such arbitrator by
such judge on such application shall have precisely the same force and effect as
if such arbitrator had been appointed by the two arbitrators. If for any reason
the third arbitrator cannot be appointed in the manner prescribed by the
preceding sentence, either regularly appointed arbitrator, or either party to
the arbitration, may apply to the American Arbitration Association for
appointment of the third arbitrator in accordance with the Rules. Should the
party upon whom the demand for arbitration has been served fail or refuse to
appoint an arbitrator within 20 days, the single arbitrator shall have the right
to decide alone, and such arbitrator's decision or award shall be final and
binding upon the parties. The decision of the arbitrator shall be in writing and
shall set forth the basis therefor. The Partners shall abide by all awards
rendered in arbitration proceedings, and all such awards may be enforced and
executed upon in any court having jurisdiction over 

                                     - 35 -

<PAGE>



the party against whom enforcement of such award is sought. The Partners shall
divide equally the administrative charges, arbitrator's fees, and related
expenses of arbitration, but each Partner shall pay its own legal fees incurred
in connection with any such arbitration. This agreement to arbitrate shall be
specifically enforceable under the prevailing arbitration law and the parties
stipulate that this Agreement involves interstate commerce.

by all proper and necessary corporate actions.

     13.02. Absence of Violation. Each Partner warrants to the other that
neither the execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby will constitute a violation of, or a default
under, or conflict with, 

                                     - 36 -

<PAGE>

any term or provision of the charter or by-laws of the warranting Partner or any

Partnership, and neither Partner shall use these techniques, equipment,
supplies, technologies or patents except as provided in this Section. The
Partnership shall give both Partners the right to bid for the right to own and
engage in exclusive marketing of such items (such right to be subject to the
Partnership's exclusive right to market and use such items during the term of
this Agreement with regard to Restricted Patients). Subject to negotiation of a
financial arrangement satisfactory to the Partnership, the Partner submitting
the highest bid shall be granted said ownership and marketing rights. In the
event that the Partners are unable to negotiate such an arrangement, the matter
may be submitted by either Partner to 

                                     - 37 -

arbitration pursuant to ARTICLE XII hereof. To the extent that such ownership
and marketing rights are not sold to a Partner under this section, the
Technology shall be disposed of on dissolution of the Partnership in the same
manner as other Partnership assets.

     14.02. Limitation on Agency. It is specifically understood and agreed
between the Partners that this Partnership extends only to, and is limited to,
the rights and obligations under this Agreement and, except an otherwise
expressly provided herein, this Agreement shall not constitute either Partner as
the agent of, or principal for, the other Partner.

     14.03. Other Activities. Nothing in this Agreement shall be construed to
restrict either Partner from carrying on any business or activity (other than as
specifically stated in Article II hereof), whether or not any such business or
activity is competitive with the business of the Partnership.

     14.04. Inspection of Records. Each Partner or its authorized representative

following the last date services are furnished by the Partnership. If the
Partnership carries out any of the duties of this Agreement through an agreement
between it and a Partner or other individual or organization related to it,
Partnership shall require that a clause be included in such agreement to the
effect that until the expiration of four (4) years after the furnishing of such
services pursuant to such an agreement, the related organization shall make

approvals, or other communications which may be or are required to be given,

                           DRUG DISTRIBUTION BUSINESS
                        MANAGEMENT AND SERVICE AGREEMENT

     This Management and Service Agreement (hereinafter referred to as the
"Agreement") is made and entered into this 1st day of July, 1994, by and between
SOUTHERN HEALTH SYSTEMS, INC., a Tennessee corporation (hereinafter referred to
as "SHS") and TEXAS HEALTH PHARMACEUTICAL RESOURCES, a Tennessee general
partnership (hereinafter referred to as "THPR");

                              W I T N E S S E T H:

     WHEREAS, THPR has been formed to engage in the business of providing
distribution of certain drugs (the "Drug Distribution Business"); and

     WHEREAS, THPR desires to obtain from SHS, and SHS is willing to provide to
THPR, certain services necessary or desirable in the conduct of THPR's Drug
Distribution Business, all upon the terms and subject to the conditions
hereinafter set forth;

     NOW, THEREFORE, for and in consideration of the mutual promises contained
herein and for other good and valuable consideration, the receipt and adequacy
of which is hereby acknowledged, the parties hereto agree as follows:

<PAGE>

         1.        Services to be Provided by SHS.  During the term of this

Agreement, SHS agrees to provide or arrange for the provision of, the following
services to THPR:

         A. Billing, Reimbursement, Collection and Financial Counseling
Services.

                  (i) Services. SHS shall provide such billing, reimbursement,
                  collection and financial counseling services as are required,
                  or reasonably requested, by THPR in conducting its Drug
                  Distribution Business, including the preparation, transmitting
                  and monitoring of all bills to patients of THPR's Drug
                  Distribution Business or third party payors, preparing
                  requests or otherwise assisting patients of THPR's Drug
                  Distribution Business in seeking reimbursement from all third
                  party payors for the services provided to such patients by
                  THPR, collecting amounts due THPR from patients or third
                  parties, and counseling patients regarding the options
                  available to them in paying for the Drugs and related services
                  provided to them by THPR. THPR shall establish all patient
                  charges for 

                                           2

<PAGE>

                  such Drugs and related services provided by THPR to the 
                  patients.

                  (ii) Clearance of Patients. SHS agrees that it will not commit
                  to provide Drugs or related services to any patient until such
                  patient is approved by THPR. THPR shall promptly notify SHS as
                  to any potential patient and shall obtain such patient data as
                  shall be specified by SHS. SHS agrees to promptly investigate
                  a potential patient's insurance coverage and financial ability
                  to pay and to notify THPR as to the patient's financial
                  ability to pay for Drugs or related services from THPR. THPR
                  shall thereafter obtain all documentation necessary to file
                  claims with third party payors and forward same to SHS. SHS
                  shall have no liability for relying upon information provided
                  by third party payors concerning coverage in the event that
                  such information shall subsequently prove to be incorrect.

                  (iii) Collection and Disbursement. SHS shall monitor and
                  coordinate collection, for and on behalf of THPR, of all
                  monies due to THPR from patients and/or third party payors for
                  Drugs and related services. SHS shall deposit said funds into
                  a bank account designated by 

                                           3

<PAGE>

                  THPR. SHS shall not have authority to disburse funds from
                  said bank account. However, funds from said Account, in an
                  amount determined by THPR, shall be deposited in a separate
                  operating account, and SHS shall have authority to disburse
                  funds from this operating account as necessary to carry out 
                  the management functions specified herein. Collections of all
                  accounts are performed by SHS on behalf of THPR and SHS shall
                  not be responsible for any failure to collect such accounts. 
                  SHS hall use reasonable efforts to collect said accounts 
                  (but not greater than those efforts used in the collection of
                  its own accounts), but SHS shall not be required to institute
                  suit for collection or incur any extraordinary expenses in 
                  attempting to collect these receivables unless such action is
                  approved by the Steering Committee and the costs are paid by 
                  THPR.

     B. Accounting and Financial Reporting. SHS shall provide the following
accounting and financial reporting services required by THPR in the conduct of
its Drug Distribution Business: (i) monthly, quarterly and annual financial
statements consisting of income statements, balance sheets, a detailed General
Ledger and Status Report of Collections, (ii) all sales tax returns and reports,
(iii) schedules of accounts receivable, 

                                           4

<PAGE>

accounts payable and cash applications, (after applying cash received to
appropriate invoices, applying credits to patient accounts and applying
write-offs and adjustments approved by THPR) and (iv) reconciliation of the Drug
Distribution Business bank account statements of THPR. SHS shall not make
provision for any annual audit of THPR, and such audit if desired by THPR shall
be the responsibility of THPR and shall be conducted by such independent
accounting firm as THPR may select. SHS agrees to cooperate with the accounting
firm in the conduct of the audit of THPR or any other accounting procedure for
which the accounting firm may be engaged by THPR. THPR shall make available to
SHS such information and documentation as may be needed to enable SHS to prepare
the tax returns and financial reports specified herein.

         C.       Management Services and Marketing.

                  (i) Responsibilities. THPR hereby appoints SHS to manage and
                  supervise the operation of THPR's day-to-day operations of its
                  Drug Distribution Business and for this purpose, THPR
                  delegates to SHS the authority to make, subject to the terms
                  hereof, such management decisions as are necessary for the
                  day-to-day operations of THPR's Drug Distribution Business.
                  SHS accepts this engagement and agrees to faithfully 

                                           5

<PAGE>

                  perform the duties and responsibilities set out herein. 
                  In carrying out its management responsibilities, and in 
                  accordance with the provisions of this Agreement, SHS shall
                  be subject to the direction, input and general guidance of 
                  the Steering Committee. The Steering Committee shall 
                  communicate to SHS all decisions of that Committee which 
                  affect the duties and responsibilities of SHS under this 
                  Agreement.

                  (ii) Marketing. SHS shall also provide such procedure manuals,
                  and marketing materials as SHS may from time to time determine
                  to be helpful in the operation of THPR's Drug Distribution
                  Business and upon the direction of the Steering Committee, SHS
                  personnel shall perform sales calls and other related
                  marketing activities. Such marketing materials and procedure
                  manuals are deemed confidential by SHS and shall be available
                  for review by THPR at SHS's offices.

                  (iii) Personnel. SHS shall designate certain SHS personnel to
                  perform the management functions set out hereunder and such
                  SHS personnel shall supervise the operation of THPR's Drug
                  Distribution Business. Subject to the reimbursement provisions
                  set out in 

                                           6

<PAGE>

                  Section 2 hereinbelow, SHS shall solely be responsible for 
                  all costs associated with such employment, including without 
                  limitation, its employees' salaries, federal and state income
                  tax withholding, Social Security tax withholding, workmen's 
                  compensation benefits and fringe benefits.

                  (iv) Steering Committee. The overall management and control of
                  the business and affairs of THPR's Drug Distribution Business
                  shall be vested in a Steering Committee as described in the
                  THPR Partnership Agreement.

     2. Compensation. THPR shall pay a monthly fee to SHS for the reimbursement,
accounting, management and computer services specified herein as set out on
Exhibit A attached hereto and made a part hereof, plus an amount equal to *
percent (*%) of net patient revenues of THPR during that month. Net patient
revenue shall be determined in accordance with generally accepted accounting
principles. SHS will bill THPR for all charges for services and employment costs
on a monthly basis. All charges shall be due and payable by THPR * (*)
days from the end of the month in which the changes reflected on SHS's invoice
to THPR were earned by SHS.



* Omitted information is the subject of a request for confidential treatment 
  pursuant to Rule 406 under the Securities Act of 1933 and has been filed 
  separately with the Securities Exchange Commission.



                                           7
<PAGE>

         Notwithstanding any provision herein to the contrary, the * percent
of net patient revenues when added to similar fees (excluding reimbursement,
accounting, management and computer service fees as described on Exhibit A) paid
to SHS by all other partnerships between an SHS affiliate and Alternative Care
Systems, Inc. shall not exceed for fiscal year July 1, 1994 through June 30,
1995 the sum of $*. If the total should exceed this amount, SHS shall
determine which of the fees paid by these partnerships to SHS shall be reduced.
The management fees are based on the assumption that the homecare reimbursement
market remains relatively stable. If significant changes in the Texas Medicaid
levels of reimbursement or other unforeseen material changes occur, then the
parties to this Agreement will mutually review other options for compensation.
The management fees set out in this section will be effective from July 1, 1994
to June 30, 1995 unless one of the unforeseen events referenced hereinabove
should occur. Both parties will review the previous years fees and their
reasonableness on an annual basis and resolve outstanding issues and agree to
the fees and cap on fees for the following year. In the event that the parties
cannot agree, the management fees shall remain the same as for the prior fiscal
year ending June 30.

     3. THPR Costs. It is agreed and understood that during the term of this
Agreement, THPR shall also be responsible for 


* Omitted information is the subject of a request for confidential treatment 
  pursuant to Rule 406 under the Securities Act of 1933 and has been filed 
  separately with the Securities Exchange Commission.

                                           8
<PAGE>

the costs incurred by SHS in providing the services which it is obligated to
provide under Sections 1A, 1B and 1C hereunder (including without limitation,
telephone, travel, office supplies and postage). In addition to the preceding
provision, THPR shall be responsible for the costs of salaries and fringe
benefits for THPR's employees, if any; outside auditor fees; acquisition of
Drugs; facility lease costs; capital expenditures; principal and interest on
loans; payroll taxes for its employees, if any; and the cost of preparing
Federal and state Income Tax returns, and all sales taxes on sales to patients.
THPR shall contract for all such expenses for and in the name of THPR, without
basing the same upon SHS's credit, and SHS shall not be liable to third party
providers for the costs of such goods and services. SHS shall file for and on
behalf of THPR all sales and use tax returns necessary in the operation of
THPR's Drug Distribution Business.

     4. Subcontracting. The parties to this Agreement recognize that SHS may
provide to THPR certain of the services which it is obligated to provide under
this Agreement by means of subcontracts with third parties. However, no such
subcontract shall release SHS from its duties and responsibilities under this
Agreement with respect to the services so subcontracted.

                                           9
<PAGE>

     5. Term. This Agreement shall be for a term beginning on July 1, 1994 and
ending on March 31, 1999, unless otherwise terminated in accordance with this
section. This Agreement shall automatically terminate upon (i) SHS or THPR
ceasing to exist, (ii)either party ceasing to be licensed to sell Drugs, (iii)
either party permanently ceasing to engage in the Drug Distribution Business,
(iv) the mutual agreement of the parties, (v) the insolvency or bankruptcy of
either party, the making by either party of an assignment for the benefit of
creditors, the consent by either party to the appointment of a trustee or
receiver, or the appointment without its consent, of a trustee or receiver for
it or for a substantial part of its property, or (vi) the institution by or
against either party of bankruptcy, reorganization, arrangement or insolvency
proceedings. In addition, if either party hereto shall breach the terms of this
Agreement, the nonbreaching party may give written notice of the breach to the
breaching party, and if said breach is not cured within 21 calendar days
following the giving of said notice, this Agreement shall at the option of the
nonbreaching party be terminated. Furthermore, notwithstanding any other
provision of this Agreement, either party may terminate this Agreement upon
giving 90 days prior written notice to the other party.

     6. Force Majeure. The obligations of SHS hereunder shall be excused during
any period of delay caused by matters such as 

                                           10
<PAGE>

strikes, acts of God, shortages of raw materials or power, inability to obtain
product, governmental action or compliance with governmental requirements,
whether voluntary or pursuant to order, or any other matter which is beyond the
reasonable efforts of SHS to control.

     7. Severability. If any one or more of the provisions of this Agreement
shall for any reason be held illegal or invalid, such illegality or invalidity
shall not affect any other provision of this Agreement and this Agreement shall
be enforced as if such illegal or invalid provision had not been contained
herein.

     8. Confidentiality. Each party has developed or may during the term hereof
develop certain formulae, products, methods of doing business, customer lists
and other proprietary information which that party deems to be confidential and
a trade secret. In the course of fulfilling their respective obligations
hereunder, some of these formulae, products, methods and other proprietary
information will become known to the other party hereto. It is contemplated that
each employee or agent of the parties who will be exposed to such confidential
information will be required to execute a confidentiality agreement with each
party hereto. Each party also agrees that it will not duplicate, make use of, or
disclose, in any manner whatsoever, any 

                                           11
<PAGE>

information which is deemed to be confidential by the other party, either during
or after the term of this Agreement, without the express prior written consent
of the other party hereto.

      In the event that any information deemed to be confidential by a party is
provided to the other party or its employees or agents in writing, the party
providing same shall mark the writing as "confidential." In the event that such
information is provided in non-written form such as orally, by audiotape,
videotape or computer software or disc, the party claiming such information to
be confidential shall furnish to the other party a written list containing a
brief description of such item and designating such item as confidential. Upon
termination of this Agreement, all copies of any information hereunder deemed,
or designated by a party as, confidential shall be returned to the party who
supplied the information, or who designated same as confidential.
Notwithstanding the preceding provision, the following types of information
provided by a party shall always be deemed confidential, whether or not so
designated: patient records; prescription files; costs of goods and supplies;
and financial records of the party.

     Notwithstanding the preceding sections, this restriction shall not apply
(i) to any information which is not deemed confidential hereunder, or which has
not been designated as 

                                           12
<PAGE>

confidential in the manner specified herein, (ii) to any information which was
known to a party prior to its disclosure by the other party, (iii) to any
information which is or becomes public knowledge through no failure of a party
bound by this Agreement, (iv) to any information which is independently
developed by a party hereto, or (v) to the extent that such restrictions
conflict with the terms of the THPR Partnership Agreement.

     It is recognized and acknowledged that damages caused by a party's breach
of this Section would be difficult to ascertain and would not adequately
compensate the other party for its losses. Therefore, both parties agree that
the party claiming a breach of this Section shall be entitled to injunctive
relief to restrain the commission or continued commission of said breach by
seeking such relief from a court of competent jurisdiction.

         9.   Service to Other Businesses.  THPR acknowledges that

SHS offers its services to other business, and THPR agrees that no provision
contained herein shall restrict or prohibit SHS from providing services to
others in addition to THPR as long as the performance of said services does not
interfere with the performance of SHS's obligations hereunder.

                                           13

         10. Records. To the extent required by Section 1861(b)(1)(I) of the
Social Security Act, SHS shall, upon proper request, allow the United States
Department of Health and Human Services, the Comptroller General of the United
States and their duly authorized representatives, access to this Agreement and
to all books, documents and records necessary to verify the nature and extent of
the costs of the services provided by SHS under this Agreement at any time
during the term of this Agreement and for an additional period of four (4) years
following the last date services are furnished under this Agreement.

         11. Nonassignability. The rights, duties and responsibilities of the
parties hereto are personal in nature and shall not be assigned without the
express written consent of the other party except that SHS may subcontract with
other parties to perform some or all of its duties hereunder.

     12. Applicable Law. This Agreement shall be construed in accordance with
the laws of the State of Tennessee and the laws of the State of Tennessee shall
govern the rights, duties, liabilities and responsibilities created hereunder.

     13. Headings. All headings used herein are for ease of reference only and
shall in no way be construed as interpreting, decreasing or enlarging the
provisions of this Agreement.

                                           14

     14. Effect. This Agreement shall be binding upon and shall inure to the
benefit of the parties hereto, their successors, administrators, trustees and
assigns.

     15. Modification. This Agreement constitutes the entire understanding
between the parties hereto and may be changed or modified only with the written
consent of both parties.

                 replicating Company's signature, or the signature of an

                  individual authorized to act on behalf of Company, and 
                  Company's provider number, for the limited purposes of 
                  billing Company's patients, filing claims with the 
                  applicable third party payors to effectuate payment for 
                  Hemophilia Therapy Goods, and collecting and depositing 
                  accounts receivable. Bills shall be on the appropriate 
                  standardized form (i.e., 1500 claim form) or through 
                  electronic filing if available.

                  4. Collection and Disbursement. THPR shall monitor and 
                  coordinate collection of all monies due to the Company from 
                  patients and/or third party payors for Hemophilia Therapy 
                  Goods and related services. THPR shall deposit all Company 
                  funds received by it into the bank account designated by 
                  the Company. THPR shall not have authority to disburse 
                  funds from said bank account. Collections of all accounts 
                  are performed by THPR on behalf of the Company and THPR 
                  shall not be responsible for any failure to collect such 
                  accounts. THPR shall use reasonable efforts to collect said 
                  accounts (but not greater than those efforts used in the 
                  collection of its own accounts) but THPR shall not be 
                  required to institute suit for collection or incur any 
                  extraordinary expenses in attempting to collect these 
                  receivables unless such action is approved by the Company 
                  and the costs are paid by the Company.

                  5. THPR shall comply with the rules, regulations and 
                  requirements of third party payors in seeking reimbursement 
                  of behalf of the Company.

         C. Accounting and Financial Reporting. THPR shall provide the 
         following accounting and financial reporting services required by 
         the Company in the conduct of its Hemophilia Therapy Business: (a) 
         monthly and annual financial statements consisting of income 
         statements, balance sheets, and Status Report of Collections, (b) 
         schedules of accounts receivable (after applying cash received to 
         appropriate invoices, applying credits to patient accounts and 
         applying write-offs and adjustments approved by the Company).

         D. Audits. THPR and Company understand that they are subject to 
         audits (by the United States Department of Health and Human Services 
         ("Department") and participating manufacturers) of records that 
         directly pertain to Company's compliance with the drug resale or 
         transfer prohibition and the prohibition against duplicate Medicaid 
         rebates and 340B discounts. THPR will assure that all pertinent 
         reimbursement accounts and dispensing records, maintained by THPR, 
         will be separate from THPR's own operations and will be accessible 
         to Company, the Department, and the manufacturer in the case of a 
         manufacturer audit.

         However, THPR shall not make provision for any annual audit of the 
         Company, and such audit if desired by the Company shall be the 
         responsibility of the Company and shall be conducted by such 
         independent accounting firm as the Company may select. THPR agrees 
         to cooperate with the accounting firm in the conduct of the audit of 
         the Company or any other accounting procedure for which the 
         accounting firm may be engaged by the Company. Company shall make 
         available to THPR such information and documentation as may be 
         needed to enable THPR to prepare the financial reports specified 
         herein and meet the audit requirements established by the Office of 
         Drug Pricing.


         E.       Management Services and Marketing.

                  1. Responsibilities. Company hereby appoints THPR to manage 
                  and supervise the operation of the Company's day-to-day

                  purpose, Company delegates to THPR the authority to make, 
                  subject to the terms hereof, such management decisions as 
                  are necessary for the day-to-day operations of the 
                  Company's Hemophilia Therapy Business. THPR accepts this 
                  engagement and agrees to faithfully perform the duties and 
                  responsibilities set out herein.

                  such THPR personnel shall supervise the operation of the 
                  Company's Hemophilia Therapy Business.

                   All such employees shall remain employees of THPR and THPR 
                  shall retain control and supervision of such employees.

         F.       Pharmacy Services.

                  1.       Agency.  THPR will act as the pharmacy agent of 
                  Company for dispensing Hemophilia Therapy Goods sold by 
                  Company to Approved Patients of the Company pursuant to a 
                  prescription.

                  2. Purchasing and Shipment. Company will purchase 
                  Hemophilia Therapy Goods and assume responsibility for 
                  establishing its price, pursuant to any applicable consumer 
                  protection laws and pursuant to the terms of the Public 
                  Health Services grant. Company agrees to adhere to all 
                  rules and regulations established by the PHS in connection 
                  with its grant of federal funds giving rise to Company's 
                  Covered Entity status. Company will order outpatient drugs 
                  for Approved Patients of the Company from a participating 
                  drug 

                                       9

<PAGE>

                  manufacturer during the term of this Agreement and direct 
                  that the Outpatient Drugs be billed in the name of Company 
                  and delivered to THPR for storage and dispensing to 
                  Approved Patients of the Company.

                  Notwithstanding any Contracted Pharmacy Service provided by 
                  THPR, including inventory management, Company understands 
                  and agrees that it is Company's responsibility to order a 
                  sufficient quantity of Outpatient Drugs from a 
                  participating manufacturer necessary to meet the 
                  prescription needs of the Approved Patients of the Company.

                  Company understands and agrees that THPR is acting as a 
                  warehouse for Outpatient Drugs ordered by Company until 
                  such time as THPR receives a request from Company to 
                  dispense outpatient drugs to an Approved Patient of the 
                  Company and that Company retains legal title to such 
                  outpatient drugs until the outpatient drugs have been 
                  dispensed. Company will make timely payments for the 
                  Hemophilia Therapy Goods delivered to THPR pursuant to 
                  Company's order.

                           THPR will also monitor the receipt of Hemophilia 
                  Therapy Goods, and report the quantities of Hemophilia 
                  Therapy Goods received. THPR will compare all shipments 
                  received to the orders and inform Company of 

                                       10

<PAGE>

                  any discrepancy within five (5) business days of receipt.

                  3. Services. THPR will provide all Contract Pharmacy 
                  Services for the Company. THPR will secure the 
                  prescription, dispense the Hemophilia Therapy Goods, 
                  maintain a summary of receiving and dispensing records, 
                  provide drug utilization review, provide formulary 
                  maintenance, provide patient profiles, and provide follow 
                  up documentation as required by the Office of Drug 
                  Pricing's Contract Pharmacy Services Guidelines.

                  4. Patient Choice. Company will inform its patients of his 
                  or her freedom to choose a pharmacy provider on a form 
                  substantially similar to Exhibit A of this Agreement. If 
                  the patient does not elect to use the contracted services 
                  of THPR, the patient may obtain the prescription from the 
                  Company and then obtain the Hemophilia Therapy Goods from 
                  the pharmacy of his or her choice. When a patient obtains 
                  Hemophilia Therapy Goods from a retail pharmacy other than 
                  THPR, the manufacturer is not required to offer Hemophilia 
                  Therapy Goods at 340B pricing.

                  5.       Pharmacy Records.  THPR shall maintain such 
                  pharmacy records as required by state and local 
                  governmental entities. Such records shall be the 

                                       11

<PAGE>

                  property of THPR; however, copies will be made available to 
                  Company to the extent allowed by law.

         G. Prohibition of Drug Diversion. THPR and Company agree that they 
         will not resell or transfer Hemophilia Therapy Goods purchased at 
         section 340B pricing to an individual who is not a Approved Patient 
         of Company. Company understands that it can be removed from the list 
         of covered entities because of its participation in drug diversion, 
         a 340B(a)(5) prohibition, and no longer be eligible for 340B 
         pricing. Company understands that Agreement is contingent upon it 
         maintaining its Covered Entity status and agrees to inform THPR (no 
         later than one (1) business day after becoming aware of same) of the 
         loss of its status as a Covered Entity.

                  1.       Dispensing of Hemophilia Therapy Goods.  THPR will 
                           dispense Hemophilia Therapy Goods only in the 
                           following circumstances:

                           a. Upon presentation of a prescription bearing 
                           Company's name, the eligible patient's name, a 
                           designation that the patient is an eligible 
                           patient, and the signature of a legally qualified 
                           health care provider affiliated with Company; or

                           b. Receipt of a prescription ordered by 

                                       12

<PAGE>

                           telephone on behalf of an eligible patient by a 
                           legally qualified health care provider affiliated 
                           with Company who states that the prescription is 
                           for an eligible patient. Company will furnish a 
                           list to THPR of all such qualified health care 
                           providers and will update the list of providers to 
                           reflect any changes. If THPR is found to have 
                           violated the drug diversion prohibition, THPR will 
                           pay Company the amount of the discount in question 
                           so that Company can reimburse the manufacturer.

                  2.       Patient Eligibility.

                           a. Company and THPR will develop a system to 
                           verify patient eligibility. As used in the context 
                           of this Agreement, an individual is a "patient" of 
                           Company (with the exception of State-operated or 
                           funded AIDS drug purchasing assistance programs) 
                           only if:

                                    1.      Company has established a 
                                    relationship with the individual, such 
                                    that Company maintains records of the 
                                    individual's health care; and

                                    2.       the individual receives health 
                                    care services from a health care 
                                    professional who is either employed by 
                                    Company or provides

                                       13

<PAGE>

                                    health care under contractual or other 
                                    arrangements (e.g. referral for 
                                    consultation) such that responsibility 
                                    for the care provided remains with 
                                    Company; and

                                    3. the individual receives a health care 
                                    service or range of services from Company 
                                    which is consistent with the service or 
                                    range of services for which grant funding 
                                    or Federally-qualified health center 
                                    look-alike status has been provided to 
                                    Company.

                           b. An individual is not a "patient" of Company for
                           purposes of 340B if the only health care service
                           received by the individual from Company is the
                           dispensing of a drug or drugs for subsequent
                           self-administration or administration in the home
                           setting.

                           c. An individual registered in a State-operated or
                           funded AIDS drug purchasing assistance program
                           receiving financial assistance under title XXVI of
                           the Public Health Services Act will be considered a
                           "patient" of Company for purposes of this
                           definition if so registered as eligible by the
                           State program.

                                       14

         H. Tracking Service. THPR, with the assistance of Company, will
         establish and maintain a tracking system suitable to prevent diversion
         of section 340B discounted drugs to individuals who are not Approved
         Patients of the Company. For example, such a tracking system might
         include quarterly sample comparisons of eligible patient prescriptions
         to the dispensing records and a six (6) month comparison of 340B drug
         purchasing and dispensing records as is routinely done in other
         reconciliation procedures. Customary business records may be used for
         this purpose.

                  Company will verify, using THPR's (readily retrievable)
         customary business records, that a tracking system exists which will
         ensure that any Hemophilia Therapy Goods purchased under the Veteran's
         Health Care Act of 1992 are not diverted to individuals who are not
         Approved Patients of Company. Such records may include: prescription
         files, velocity reports, and records of ordering and receipt. These
         records will be maintained for the period of time required by State law
         and regulations.

                  Prior to THPR providing pharmacy services pursuant to this
         Agreement, Company will have the opportunity, upon reasonable notice
         and during business hours, to examine the tracking system. Company will
         establish a process for a periodic random (sample) comparison of its
         prescribing

                                       15

<PAGE>

         records with THPR's dispensing records to detect potential
         irregularities. THPR will permit Company or its duly authorized
         representatives to have reasonable access to THPR's facilities and
         records during the term of this Agreement in order to make periodic
         checks regarding the efficacy of such tracking systems. THPR agrees to
         make any and all adjustments to the tracking system which Company
         advises are reasonably necessary to prevent diversion of the Hemophilia
         Therapy Goods to individuals who are not Approved Patients of the
         Company.

         I. Handling and Labeling. THPR agrees that all Hemophilia Therapy Goods
         provided by Company shall be labeled in accordance with applicable
         Federal, State and local law and that said Hemophilia Therapy Goods
         shall be stored, shipped and handled by THPR in accordance with
         recognized professional standards for handling and storage of such
         products and in accordance with Company's policies and procedures to
         the extent that same do not contradict the requirements of Federal,
         State and local law. As part of preparing Hemophilia Therapy Goods for
         shipment, THPR shall pack the goods in cartons or other suitable
         packaging with such cooling packs, insulation, or other packing
         materials as necessary. All Hemophilia Therapy Goods shall be 
         delivered to Company's patients on behalf of Company, by Federal 
         Express or other acceptable courier, with the cost of said 

                                       16

<PAGE>

         delivery to be paid by THPR.

         J. Other Services. Regardless of the fact that THPR has agreed in this
         Agreement to provide services other than Contract Pharmacy Services to
         Company, access to 340B pricing will always be restricted to only
         Approved Patients of the Company.

         III. Compensation. In exchange for the services provided by THPR under
Sections IIA through IIJ of this Agreement, the Company agrees to pay THPR a
monthly fee as set out on Exhibit B. Said fee shall be determined on a monthly
basis by THPR and THPR shall at the end of each calendar month during the term
of this Agreement submit invoices to the Company setting out the amounts due
THPR for said month. The invoices for THPR's services shall be due and payable
* (*) days from the receipt of same by the Company, except that the first
months invoice will be due in * (*) days. Both parties acknowledge and
agree that the fees established for the Contracted Pharmacy Services have been
set in advance, are consistent with fair market value derived in an arms-length
transaction, and have not been determined in a manner that takes into account
the volume or value of any referrals or business otherwise generated between the
parties.

         IV. Company Costs. It is agreed and understood that during the term of
this Agreement, THPR shall be responsible for the 

                                       17

<PAGE>

costs incurred in providing the services which it is obligated to provide
hereunder, and that THPR shall pay such costs out of its compensation received
under Section III. Notwithstanding the preceding provision, the Company shall be
responsible for the costs of salaries and fringe benefits for the Company's
employees, if any; cost of goods; outside auditor fees; interest expense; state
taxes; principal on Company loans; depreciation; and payroll taxes for its
employees, if any, and the cost of preparing the Company's Federal and State
Income tax returns. All such expenses shall be contracted for and in the name of
the Company, based solely upon the Company's credit, and THPR shall not be
liable to third party providers for the costs of such goods and services.

         V. Subcontracting. The parties to this Agreement recognize that THPR
may provide to the Company certain of the goods and services which it is
obligated to provide under this Agreement by means of subcontracts with third
parties, provided however that the use of subcontractors shall not relieve THPR
of its obligations hereunder.

         VI. Indemnity and Insurance. THPR and Company hereby agree that:

         A. THPR shall assume responsibility for and shall indemnify and hold
         Company harmless and defend Company from all losses (including claims
         for injuries to employees of THPR or of Company), expenses, attorneys'
         fees, damages, 

                                       18

<PAGE>

         claims and judgments awarded to third parties resulting solely from
         the negligent acts or omissions or wrongful acts of THPR, its agents
         or employees;

         B. Company shall assume responsibility for and shall indemnify and hold
         THPR harmless and defend THPR from all losses (including claims for
         injuries to employees of THPR or of Company), expenses, attorneys'
         fees, damages, claims and judgments awarded to third parties resulting
         solely from the negligent acts or omissions or wrongful acts of
         Company, its agents or employees.

         The indemnities and assumptions of liabilities and obligations herein
provided for shall continue in full force and effect notwithstanding the
termination of this Agreement whether by expiration of time, by operation of law
or otherwise. Each party hereto agrees to reimburse the other party for its
attorneys fees incurred in enforcing the provisions of this Agreement. This
obligation shall only apply when the party seeking to recover attorneys fees has
obtained a final non-appealable judgment from a court of competent jurisdiction
holding that a breach of this Agreement has occurred and awarding dollar damages
as a result of said breach. THPR, during the term of this Agreement, will
provide through a related entity at its sole cost and expense, general public
liability, products liability and property damage insurance in limits of not
less than $1,000,000.00 per incident; 

                                       19

<PAGE>

and $3,000,000.00 per annum aggregate. All policies insuring against liability
for bodily injury or death or damage to property shall include coverage for
malpractice if such exposure exists and shall insure THPR against the matters
covered by THPR's contractual duty to indemnify the Company set out hereinabove.

         THPR will provide Company with certificates evidencing the insurance
required hereunder, and all such policies shall provide that notice of
cancellation or termination thereof shall be provided in advance to Company. In
the event of cancellation or termination of the coverage described herein, THPR
shall immediately obtain substitute or replacement coverage.

         VII. Term. This Agreement shall be for a term beginning on the date of
the execution hereof and expiring on March 31, 1999, unless otherwise terminated
in accordance with this section. This Agreement shall automatically terminate
upon (a) THPR or the Company ceasing to exist or upon either party ceasing to be
licensed to sell Hemophilia Therapy Goods or upon either party permanently
ceasing to engage in the Hemophilia Therapy Business, (b) the mutual agreement
of the parties, (c) upon notice by either party hereto given twelve months prior
to the effective date of termination, (d) upon the insolvency or bankruptcy of
either party, the making by either party of an assignment for the benefit of
creditors, the consent by either party to the appointment of a trustee or
receiver, or the appointment without its consent, of a 

                                       20

<PAGE>

trustee or receiver, for it or for a substantial part of its property, or (e)
the institution by or against either party of bankruptcy, reorganization,
arrangement or insolvency proceedings.

 In addition, if either party hereto shall breach the terms of this Agreement,
the nonbreaching party may give written notice of the breach to the breaching
party, and if said breach is not cured within fourteen (14) business days
following the giving of said notice, this Agreement shall at the option of the
nonbreaching party be terminated. Notwithstanding the above, this Agreement
shall be terminated immediately in the event that Company loses its status as a
Covered Entity as defined herein, or if any federal or state law is enacted
which could make this Agreement impractical including, but not limited to, a law
which limits the Company's ability to bill third party payors in excess of the
Company's acquisition cost plus a dispensing fee for outpatient drugs purchased
under Section 340B of the Public Health Services Act.

         VIII. Applicable Patients. This Agreement only applies to individuals
who are patients of the Company and who are covered under the Chronically Ill
and Disabled Children's Services Program or Medicare or who pay with private
insurance or personal funds. This Agreement does not apply to patients who are
covered under the state Medicaid program.

         IX. Force Majeure. The obligations of THPR hereunder shall 

                                       21

<PAGE>

be excused during any period of delay caused by matters such as strikes, acts of
God, shortages of raw materials or power, governmental action or compliance with
governmental requirements, whether voluntary or pursuant to order, or any other
matter which is beyond the reasonable efforts of THPR to control.

         X. Independent Contractor. It is agreed that THPR shall be an
independent contractor, and not an employee of the Company.

 THPR shall have sole control and discretion in the manner of performing its
obligations under this Agreement and the Company shall not be responsible for
the acts of THPR while THPR is performing services under this Agreement. THPR is
solely responsible for its employees' salaries, federal and state income
withholding, social security tax withholding, workmen's compensation benefits
and fringe benefits.

         XI. Severability. If any one or more of the provisions of this
Agreement shall for any reason be held illegal or invalid, such illegality or
invalidity shall not affect any other provision of this Agreement and this
Agreement shall be enforced as if such illegal or invalid provision had not been
contained herein.

         XII. Confidentiality. Each party has developed or may during the term
hereof develop certain products, methods of doing business, customer lists and
other proprietary information which that party deems to be confidential and a
trade secret. In the 

                                       22

<PAGE>

course of fulfilling their respective obligations hereunder, some of these
products, methods and other proprietary information will become known to the
other party hereto. Each party agrees that it will not duplicate, make use of,
or disclose, in any manner whatsoever, any information which is deemed to be
confidential by the other party, either during or after the term of this
Agreement, without the express prior written consent of the other party hereto.

         In the event that any information deemed to be confidential by a party
is provided to the other party or its employees or agents in writing, the party
providing same shall mark the writing as "confidential." In the event that such
information is provided in non-written form such as orally, by audiotape,
videotape or computer software or disc, the party claiming such information to
be confidential shall furnish to the other party a written list containing a
brief description of such item and designating such item as confidential. Upon
termination of this Agreement, all copies of any information hereunder deemed,
or designated by a party as, confidential shall be returned to the party who
supplied the information, or who designated same as confidential.
Notwithstanding the preceding provision, the following types of information
provided by a party shall always be deemed confidential, whether or not so
designated: patient records; prescription files; lists of patient names,
addresses or phone

                                       23

<PAGE>

numbers; lists of referring practitioner names, addresses or phone numbers;
costs of goods and supplies; and financial records of the party.

         It is recognized and acknowledged that damages caused by a party's
breach of this Section would be difficult to ascertain and would not adequately
compensate the other party for its losses. Therefore, both parties agree that
the party claiming a breach of this Section shall be entitled to injunctive
relief to restrain the commission or continued commission of said breach by
seeking such relief from a court of competent jurisdiction.

         Notwithstanding the preceding paragraphs, this restriction shall not
apply (a) to any information which is not deemed confidential hereunder, or
which has not been designated as confidential in the manner specified herein,
(b) to any information which was known to a party prior to its disclosure by the
other party, (c) to any information which is or becomes public knowledge through
no failure of a party bound by this Agreement, (d) any information which is
independently developed by a party hereto, or (e) to the extent that such
restrictions conflict with the terms of the Company Agreement evidencing the
Company.

         XIII. Service to Other Businesses. Company acknowledges that THPR
offers its services to other businesses and Company agrees that no provision
contained herein shall restrict or prohibit THPR from providing services to
others in addition to the Company as

                                       24

<PAGE>

long as the performance of said services does not interfere with the performance
of THPR's obligations hereunder.

         XIV. Records. To the extent required by Section 1861(b)(1)(1) of the
Social Security Act, THPR shall, upon proper request, allow the United States
Department of Health and Human Services, the Comptroller General of the United
States and their duly authorized representatives, access to this Agreement and
to all books, documents and records necessary to verify the nature and extent of
the costs of the services provided by THPR under this Agreement at any time
during the term of this Agreement and for an additional period of four (4) years
following the last date services are furnished under this Agreement. Upon
request, a copy of this Agreement will be provided to a participating
manufacturer which sells covered outpatient drugs to Company. All confidential
proprietary information shall be deleted from the Agreement prior to disclosure
to a manufacturer.

         XV. Nonassignability. The rights, duties and responsibilities of the
parties hereto are personal in nature and, except as stated herein, shall not be
assigned without the express written consent of the other party.

         XVI. Applicable Law. This Agreement shall be construed in accordance
with the laws of the State of Tennessee and the laws of the State of Tennessee
shall govern the rights, duties, 

                                       25

<PAGE>

liabilities and responsibilities created hereunder.

         XVII. Compliance With The Law. THPR and Company will adhere to all
Federal, State, and local laws and requirements. Both THPR and the Company are
aware of the potential for civil or criminal penalties if Company and/or THPR
violate Federal or State law.

         XVIII. Headings. All headings under herein are for each of reference
only and shall in no way be construed as interpreting, decreasing or enlarging
the provisions of this Agreement.

         XIX.  Effect.  This Agreement shall be binding upon and shall
inure to the benefit of the parties hereto, their successors,
administrators, trustees and assigns.

         XX. Modification. This Agreement may be changed or modified only with
the written consent of both parties.

         XXI. Notices. All notices, demands, requests, consents, reports,
approvals, or other communications which may be or are required to be given,
served, or sent pursuant to this Agreement shall be in writing and shall be
mailed by first class, registered or certified mail, return receipt requested,
postage prepaid, or transmitted by telegram, addressed as set out below. Each
party may designate by notice in writing a new address to which any notice,
demand, request, consent, report, approval or

                                       26

<PAGE>

communication may thereafter be so given, served or sent. Each notice, demand,
request, consent, report, approval or communication which shall be mailed in the
manner described above, or which shall be delivered to a telegraph company,
shall be deemed sufficiently given, served, sent or received for all purposes at
such time as it is delivered to the addressee (with the return receipt or the
delivery receipt being deemed conclusive evidence of such delivery) or at such
time as delivery is refused by the addressee upon presentation.

         XXII.   Licenses.  THPR is a licensed pharmacy under the laws
of Texas.  THPR agrees to maintain all licenses and permits
necessary to fulfill its obligations hereunder.

         XXIII.  Waivers.  A waiver of the breach of any provision of
this Agreement shall not be deemed a waiver of any other breach of
the same or any other provision hereof.

         XXIV. Provider. Company represents that it does not have access to
appropriate "in-house" pharmacy services as that term is used by the PHS in its
Contracted Pharmacy Service guidelines. Company understands and agrees that THPR
is the provider of Contracted Pharmacy Services to Approved Patients of the
Covered Entity during the term of this Agreement.
