                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY, AND SHOULD BE READ IN
CONJUNCTION  WITH, THE MORE DETAILED  INFORMATION AND THE CONSOLIDATED FINANCIAL
STATEMENTS, INCLUDING THE NOTES THERETO, APPEARING ELSEWHERE IN THIS PROSPECTUS.
 
                                  THE COMPANY
 
    Advance ParadigM, Inc. (the "Company") is a leading independent provider  of
pharmacy  benefit management ("PBM")  services to health  benefit plan sponsors,
based on the  over nine million  health plan members  enrolled in the  Company's
programs. The Company's primary focus is on the delivery of cost-effective, high
quality,  integrated PBM services. In addition, the Company has developed and is
expanding its clinical  expertise and  disease management services  to meet  the
specialized  needs  of its  plan members,  particularly those  requiring costly,
long-term and recurring  therapies. These  services are designed  to inform  and
educate health benefit plan sponsors, their members and participating physicians
of  nationally recognized practice  guidelines for various  disease states. This
encourages physician and member conformance, improves compliance with recognized
standards and, in turn, improves member health while reducing cost of care.
 
    The Company's PBM services include clinical and benefit design consultation,
formulary and rebate  administration, electronic  point-of-sale pharmacy  claims
processing,  mail  pharmacy  distribution,  pharmacy  network  management,  drug
utilization  review  ("DUR")  and   data  information  reporting.  The   Company
administers  a  pharmacy network  that  includes over  46,000  retail pharmacies
throughout  the   United   States.   In  1994,   in   response   to   increasing
cost-containment  pressures  from  payors,  the  Company  began  to  utilize its
clinical  and  information  systems  capabilities  to  develop  health   benefit
management   ("HBM")  services.  The  Company's  HBM  services  include  disease
management,  recommendation  of  clinical  guidelines,  patient  and   physician
profiling,  case finding  and compliance and  outcome measurement.  In 1995, the
Company began  marketing  its HBM  services  to health  benefit  plan  sponsors,
pharmaceutical  manufacturers  and  contract research  organizations,  and  as a
result, initiated programs  with selected  customers. In  addition, the  Company
intends  to leverage  its existing  capabilities and  relationships by acquiring
companies which have,  or are developing,  innovative HBM services  in order  to
provide a centralized care management alternative for its customers.
 
    It is currently estimated that annual outpatient pharmaceutical expenditures
account  for approximately  7% or  $70 billion, of  the $1  trillion health care
market, and that third-party prescriptions managed by PBMs represent a  steadily
increasing  proportion of  this amount.  In response  to escalating  health care
costs, cost  containment efforts  have  led to  rapid  growth in  managed  care.
Despite  these efforts,  continued advances in  medical technology  and new drug
development have led to  significant increases in  drug utilization and  related
costs,  creating  a  need  for  more  efficient,  cost-effective,  drug delivery
mechanisms. In  addition,  there is  rapidly  growing demand  among  payors  for
comprehensive  disease  management  programs as  cost  containment  becomes more
dependent on improvements in the quality of care. According to industry sources,
approximately 77% of large employers said  they would likely adopt some form  of
disease  management  program over  the next  two years.  HBM services  are being
developed to address  this demand through  the use of  traditional PBM  services
combined with clinical expertise and sophisticated information systems.
 
    The Company believes its clinical expertise and information systems combined
with  its PBM services provide  the Company with a  competitive advantage in the
evolving market for  HBM services.  The Company's  strategy is  to maintain  its
position  as  a leading  independent  provider of  PBM  services and  expand its
presence as a provider of  HBM services by (i)  expanding its core PBM  customer
base, (ii) expanding its HBM services, (iii) pursuing strategic acquisitions and
(iv)  continuing to establish  strategic relationships with  its major customers
and suppliers.

FORTH IN  THE FOLLOWING  RISK  FACTORS AND  ELSEWHERE  IN THIS  PROSPECTUS.  SEE
"DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS."
 
    LIMITED  OPERATING  HISTORY;  RECENT  LOSSES.   The  Company  has  a limited
operating history, as its predecessors began offering mail pharmacy services  in
1987,  clinical and  formulary management services  in 1991  and retail pharmacy
network and claims adjudication services in 1992. Through fiscal year 1994,  the
Company incurred net operating losses of $2.1 million. As of March 31, 1996, the
Company  had  an accumulated  deficit (consisting  of  net operating  losses and
accrued cumulative dividends on preferred stock) of approximately $3.0  million.
Although  the Company was profitable in fiscal years 1995 and 1996, there can be
no  assurance  that  such  profitability  will  continue  in  the  future.   See
"Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations."
 
    PRICE  EROSION.    Over  the  last  several  years,  the  PBM  industry  has
experienced  significant erosion in the  reimbursement for services. During 1994
and 1995, PBMs  affiliated with pharmaceutical  companies began to  aggressively
price  their  services,  thereby  exacerbating the  decreasing  margins  for the
industry. There can be no assurance that price erosion will not continue or that
the Company  can adequately  respond to  such price  erosion. See  "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    FLUCTUATIONS  IN QUARTERLY  OPERATING RESULTS;  LENGTHY SALES  CYCLE; FUTURE
RESULTS UNCERTAIN.  The Company has experienced and may in the future experience
significant fluctuations  in  revenue  and operating  results  from  quarter  to
quarter and from year to year due to a combination of factors, including: demand
for   the  Company's  services;  the  size,  timing  of  contract  signings  and
recognition  of  revenues  from  significant  customer  additions  and   losses;
increased  competition; the Company's  success in, and  expense associated with,
developing and  introducing  new  services; the  availability  of  rebates  from
pharmaceutical  manufacturers;  the length  of the  Company's sales  cycles; the
Company's  ability  to  increase  staff  to  meet  demand;  economic  conditions
generally  or in  specific industry segments;  and other factors  outside of the
control of the Company.  As a result of  all of these factors,  there can be  no
assurance  that the Company will  be profitable on a  quarterly or annual basis.
Due to the  foregoing, it is  possible that the  Company's operating results  in
some  future quarters will be below  analysts' expectations, which in turn could
adversely affect the  Company's stock  price. See  "Management's Discussion  and
Analysis of Financial Condition and Results of Operations."
 
    GROWTH  OF HBM  SERVICES.   The Company  is presently  expending significant
resources to develop and  expand its HBM services,  and the Company  anticipates
that it will continue to expend significant resources in the foreseeable future.
The  Company historically has experienced expense increases when introducing new
services. In addition,  the Company's  strategy for expanding  its HBM  services
entails  the acquisition of  HBM services providers,  or other transactions with
such providers to acquire  HBM services capabilities.  Because the HBM  services
market  is in an emerging stage, there can be no assurance that the Company will
be able to consummate such  acquisitions or other transactions. Moreover,  there
can  be no assurance that HBM services developed or acquired by the Company will
be profitable or that the demand for such services will exist in the future. See
"--Risk of Acquisitions."
 
    EFFECTS OF  CERTAIN  PRICING  AND  REBATE  LITIGATION.    Groups  of  retail
pharmacies  have filed several  lawsuits against drug  manufacturers and certain
PBMs in federal and state court challenging certain drug pricing practices  that
they  allege violate state  and federal antitrust laws.  The suits allege, among
other things, that  certain drug  manufacturers have offered,  and certain  PBMs
have  accepted,  discounts and  rebates on  purchases of  drugs in  violation of
federal antitrust laws.  The federal  judge overseeing  the litigation  recently
approved  a $351 million settlement agreed to by the groups of retail pharmacies
and 11 drug  manufacturers. Under  the settlement, the  drug manufacturers  must
make  the same  discounts available to  any institution, whether  a managed care
group or a  retail pharmacy,  provided that  such institution  can cause  market
share increases. The
 
                                       5
<PAGE>
judge's  decision  does not  affect the  retail pharmacies'  continuing lawsuits
against several other  drug manufacturers who  opted not to  be included in  the
settlement.  This settlement or an adverse outcome in one or more of these cases
may result in  drug manufacturers increasing  the price of  drugs for  companies
such  as the Company  or the reduction  or termination of  drug rebate programs.
Although the Company and most of its competitors have not been named as a  party
in  any such lawsuits, there can be no  assurance that in the future the Company
will not  be named  as a  defendant  in these  or similar  lawsuits  challenging
pricing, rebates or other aspects of the Company's business.
 
    MANAGEMENT  OF GROWTH.  The Company's business has grown rapidly in the last
three years,  with  total  revenues increasing  approximately  258%  from  $35.0
million in fiscal year 1994 to $125.3 million in fiscal year 1996. The Company's
recent  expansion  has  resulted in  substantial  growth  in the  number  of its
employees (from 117 at March 31, 1994 to  312 at August 31, 1996), the scope  of
its  operating  and financial  systems and  the  geographic distribution  of its
operations and  customers. This  recent rapid  growth has  placed, and  if  such
growth  continues will increasingly place, a significant strain on the Company's
management and operations. Accordingly,  the Company's future operating  results
will  depend on the ability of its  officers and other key employees to continue
implementing and  improving  its  operations,  customer  support  and  financial
control  systems, and to effectively expand, train and manage its employee base.
There can be no  assurance that the  Company will be able  to manage any  future
expansion   successfully  or  provide  the  necessary  management  resources  to
successfully manage  its business,  and any  inability  to do  so would  have  a
material  adverse  effect  on  the  Company's  business,  operating  results and
financial condition.  See "Management's  Discussion  and Analysis  of  Financial
Condition   and  Results  of  Operations--Overview"  and  "Management--Executive
Officers and Directors."
 
    DEPENDENCE ON  CERTAIN KEY  CUSTOMERS.   The Company  depends on  a  limited
number  of  large  customers  for  a  significant  portion  of  its consolidated
revenues. During fiscal  year 1996,  the Company's two  largest customers,  Blue
Cross  &  Blue Shield  of Texas,  Inc.  ("BCBS of  Texas") and  United Insurance
Company, Inc.,  accounted for  approximately 8%  and 18%,  respectively, of  the
Company's  consolidated revenues. During this period, the Company's five largest
customers accounted for approximately 44% of the Company's revenues. Loss of the
Company's accounts with BCBS of Texas  or United Insurance Company, Inc., or  of
any  other customers  which account for  a substantial portion  of the Company's
business, could  have  a material  adverse  effect on  the  Company's  business,
operating results and financial condition. See "Business-- Customers."
 
    POTENTIAL  DECLINE IN REVENUE.  More  than 20% of the Company's consolidated
revenues is attributable  to arrangements  with drug  manufacturers relating  to
volume-based  rebate payments  as well  as fees  charged for  other products and
services. The  loss  of  the  Company's  account with  any  of  the  major  drug
manufacturers  under such  arrangements or  the failure  of the  Company to meet
certain conditions under such arrangements could have a material adverse  effect
upon  the  Company's business,  operating results  and financial  condition. See
"Business--Services--Pharmaceutical Benefit Management." Over the next few years
as patents expire covering many brand name drugs that currently have substantial
market share, generic products will be introduced that may substantially  reduce
the market share of the brand name drugs. Historically, manufacturers of generic
drugs  have not  offered rebates  on their  drugs. In  addition, the  Company is
unable to predict  the effect on  rebate arrangements that  might result if  the
recent  trend  of consolidations  and  alliances in  the  drug and  managed care
industry continues, particularly between pharmaceutical manufacturers and  PBMs,
or  that might result  from an adverse  outcome in the  lawsuits filed by retail
pharmacies against  drug  manufacturers  and PBMs.  See  "--Effects  of  Certain
Pricing and Rebate Litigation." The Company provides rebate contracting services
for approximately two million lives on behalf of other PBMs. If these other PBMs
choose  to perform these services for  themselves or seek alternative suppliers,
the Company's revenues with respect to rebate contracting services would decline
which could have a material adverse effect on the Company's business,  operating
results  and financial condition.  There can be  no assurance that  the PBMs for
whom the  Company  provides  rebate  contracting services  will  not  soon  seek
alternative  suppliers or acquire the capabilities to perform these services for
themselves.
 
    CONSOLIDATION AMONG  CUSTOMERS.   Over  the  past several  years,  insurance
companies,   HMOs  and  managed  care  companies  have  experienced  significant
consolidation. The Company's managed care  customers have been and may  continue
to  be subject to consolidation pressures. Although the Company may benefit from
certain  consolidations  in  the  industry,  there  can  be  no  assurance  that
additional customers will not be lost as a result of
 
                                       6
<PAGE>
acquisitions  and  no assurance  that  such activity  will  not have  a material
adverse effect  upon the  Company's business,  operating results  and  financial
condition.  Consolidation, strategic alliances and  in general continued intense
competition in the PBM industry have resulted in the past, and may result in the
future, in the  loss of  certain of  the Company's  customers. There  can be  no
assurance  that new  and renewal  contracts will  offset the  revenues lost from
customers electing not to renew their contracts with the Company. The  Company's
contracts  with  its  customers  typically provide  for  three-year  terms, with
automatic 12-month renewals thereafter unless terminated by either party to  any
given  contract upon written notice delivered  prior to the annual renewal date.
See "--Dependence on Certain Key Customers" and "Business--Competition."
 
    COMPETITION.  The PBM  industry has become  very competitive. The  Company's
competitors  include  large,  profitable  and  well  established  companies with
substantially greater financial, marketing and other resources than the Company.
Several  competitors  in   the  PBM   business  are   owned  by   pharmaceutical
manufacturers  and may possess purchasing and  other advantages over the Company
by virtue of such ownership. Price  competition in the PBM market is  increasing
and  has resulted in reduced  margins for many PBMs,  including the Company. The
Company believes that the primary competitive factors include: independence from
drug manufacturers and  payors; the  quality, scope  and costs  of products  and
services  offered to insurance companies, HMOs,  employers and other sponsors of
health benefit plans  ("plan sponsors"  or "customers")  and plan  participants;
responsiveness to customers' demands; the ability to negotiate favorable rebates
and  volume discounts from drug manufacturers; the ability to identify and apply
effective cost containment programs  utilizing clinical strategies; the  ability
to  develop formularies; the  ability to market  PBM and HBM  services to health
benefit plan sponsors; a  strong managed care customer  base which supports  the
development  of  HBM  products and  services;  and the  commitment  to providing
flexible, clinically oriented services to  customers. There can be no  assurance
that  the  Company  will continue  to  remain  competitive with  respect  to the
foregoing factors or successfully market integrated  PBM or HBM services to  new
customers. There can be no assurance that consolidation and alliances within the
PBM  industry  will  not  adversely  impact  the  operations  and  prospects for
independent PBMs such as the Company. See "Business--Competition."
 
    RISK OF ACQUISITIONS.   Part of the Company's  strategy for growth  includes
acquisitions  of complementary  services, technologies or  businesses that could
allow the Company  to offer a  set of  integrated services, in  addition to  PBM
services,  to  better  serve the  needs  of  health benefit  plan  sponsors. The
Company's ability to  expand successfully through  acquisitions depends on  many
factors,  including the  successful identification and  acquisition of services,
technologies or businesses and management's ability to effectively integrate and
operate the acquired services, technologies or businesses. There is  significant
competition  for acquisition  opportunities in the  PBM and  HBM industries. The
Company may compete for acquisition opportunities with other companies that have
significantly greater  financial  and  management resources.  There  can  be  no
assurance  that the Company  will be successful in  acquiring or integrating any
such services, technologies  or businesses  or once acquired,  that the  Company
will  be successful  in selling  or integrating  such services,  technologies or
businesses. See "Business--Strategy."
 
    DEPENDENCE ON  KEY MANAGEMENT.    The Company  believes that  its  continued
success  will depend to a significant extent  upon the continued services of its
senior management, in particular David D. Halbert, Chairman of the Board,  Chief
Executive  Officer and President of the Company. The loss of the services of Mr.
D. Halbert or other persons in  senior management could have a material  adverse
effect  on  the  Company's business.  The  Company maintains  a  key-person life
insurance policy on Mr. D. Halbert.  The Company has entered into an  employment
agreement  with  each  of  Drs.  Filipek  and  Wright  and  Messrs.  Sattler and
Cinquegrana. See "Management--Employment Agreements."
 
    INTANGIBLE ASSETS.  At  June 30, 1996, approximately  $13.0 million, or  18%
(approximately  16%  after giving  pro forma  effect to  this Offering),  of the
Company's total assets consisted of  intangible assets. These intangible  assets
are  being amortized  over a period  of 40  years. In the  event of  any sale or
liquidation of the Company,  there can be  no assurance that  the value of  such
intangible assets will be realized. In addition, any significant decrease in the
value  of such  intangible assets  could have a  material adverse  effect on the
Company's business, operating  results and  financial condition. See  Note 2  of
Notes to Consolidated Financial Statements.
 
                                       7
<PAGE>
    GOVERNMENT REGULATION.  The PBM industry is subject to extensive federal and
state laws and regulations and compliance with such laws and regulations imposes
significant   operational   requirements   for  the   Company.   The  regulatory
requirements with which the Company must comply in conducting its business  vary
from  state to  state. Management  believes that  the Company  is in substantial
compliance with all existing statutes and regulations material to the  operation
of  its business. The impact of future legislation and regulatory changes on the
Company's business cannot be predicted, and  there can be no assurance that  the
Company  will be able to obtain or maintain the regulatory approvals required to
operate its  business. From  time  to time,  retail pharmacists  have  expressed
opposition   to  mail  order  pharmacies.   Retail  pharmacies,  state  pharmacy
associations or state  boards of  pharmacies in  some states  have attempted  to
secure  the enactment or promulgation of statutes or regulations that could have
the  effect  of  hindering  or  in  some  cases  prohibiting  the  delivery   of
prescription  drugs into such state  by a mail service  pharmacy. The Company is
also  aware  of  a  Federal  Trade  Commission  investigation  relating  to  the
acquisition  of companies in the  PBM industry, although the  Company is not, to
its knowledge, the subject of any such investigation. There can be no  assurance
that  such legislation or regulation, if subsequently adopted, or investigation,
if commenced,  would  not  have  a material  adverse  effect  on  the  Company's
business,  operating results and  financial condition. See "Business--Government
Regulation."
 
    DEVELOPMENTS IN  THE HEALTH  CARE INDUSTRY.   The  health care  industry  is
subject  to  changing political,  economic  and regulatory  influences  that may
affect the procurement practices and operation of health care organizations. The
Company's services are designed to function  within the structure of the  health
care  financing  and reimbursement  system currently  being  used in  the United
States. The  Company  believes that  the  commercial  value and  appeal  of  its
services  may be  adversely affected  if the  current health  care financing and
reimbursement system  were to  be materially  changed. During  the past  several
years, the United States health care industry has been subject to an increase in
governmental  regulation of,  among other  things, reimbursement  rates. Certain
proposals to reform  the United States  health care system  are currently  under
consideration by Congress. These proposals may increase governmental involvement
in  health care and otherwise change the operating environment for the Company's
customers. Health  care  organizations may  react  to these  proposals  and  the
uncertainty surrounding such proposals by curtailing or deferring investments in
cost  containment tools and  related technology such  as the Company's services.
The Company cannot predict what effect, if  any, such factors might have on  its
business,  operating results and  financial condition. In  addition, many health
care providers  are  consolidating to  create  integrated health  care  delivery
systems  with greater regional market power. As a result, these emerging systems
could have greater  bargaining power,  which may lead  to price  erosion of  the
Company's services. The failure of the Company to maintain adequate price levels
would  have  a  material adverse  effect  on the  Company's  business, operating
results and  financial condition.  Other  legislative or  market-driven  reforms
could  have unpredictable effects  on the Company's  business, operating results
and financial condition. See "Business--Government Regulation."
 
    POTENTIAL LIABILITY FOR RESCISSION OF PRIVATE  SALES AND UNDER SECTION 5  OF
THE  SECURITIES ACT.   Certain recent private sales  of the Company's securities
may be  required  to be  integrated  with the  offering  of securities  in  this
Offering.  If so  integrated, the  purported private  sales would  constitute an
unregistered public offering in  violation of Section 5  of the Securities  Act.
Such  a  violation  would  entitle  the subscribers  in  such  private  sales to
rescission and would  subject the  Company to  liability under  said Section  5.
Management  does not believe that rescission of  any of such private sales would
have a material adverse effect on the Company.
 
    PROFESSIONAL AND  GENERAL  LIABILITY  INSURANCE.   Various  aspects  of  the
Company's  business, including  the dispensing  of pharmaceutical  products, may
subject it to litigation and liability for damages. While the Company  maintains
and  intends to maintain professional  and general liability insurance coverage,
there can  be no  assurance  that the  Company will  be  able to  maintain  such
insurance  in the future or that such  insurance will be available on acceptable
terms or will be adequate to cover any or all potential product or  professional
liability claims. A successful product or professional liability claim in excess
of  the Company's insurance  coverage could have a  material adverse effect upon
the  Company's  business,  operating   results  and  financial  condition.   See
"Business--Liability Insurance."
 
    TAX  RISKS ASSOCIATED WITH  THE MERGER.  Immediately  prior to the Offering,
Advance Health Care, Inc. and the  Company will consummate the Merger.  Although
the    Merger   will   be   structured   as   a   tax   free   event,   if   the
 
                                       8
<PAGE>
Company were to be audited, there can be no assurance that the Internal  Revenue
Service  would not  successfully challenge the  tax free  treatment, which could
have a material adverse  effect upon the  Company's business, operating  results
and financial condition. See "The Company."
 
    NO  PRIOR PUBLIC MARKET  FOR COMMON STOCK;  DETERMINATION OF OFFERING PRICE;
POSSIBLE VOLATILITY OF STOCK PRICE.  Prior  to this Offering, there has been  no
public market for the Company's Common Stock, and there can be no assurance that
following  this Offering an active trading  market will develop or be sustained.
The initial public offering price will be determined by negotiations between the
Company and the Representatives  of the Underwriters. For  a description of  the
factors  considered  in  determining  the  initial  public  offering  price, see
"Underwriting." In  addition,  the  stock market  historically  has  experienced
volatility  which has particularly  affected the market  prices of securities of
many companies in the health care industry.
 
    ANTI-TAKEOVER  EFFECT  OF   CHARTER  PROVISIONS  AND   SERIES  B   PREFERRED
STOCK.   Certain provisions of the Company's Amended and Restated Certificate of
Incorporation (the "Restated Certificate") and  Bylaws, certain sections of  the
Delaware General Corporation Law, the ability of the Board of Directors to issue
shares  of Preferred Stock  and to establish the  voting rights, preferences and
other terms thereof without further action by the stockholders, the division  of
the  Board of Directors into three classes and  the voting terms of the Series B
Preferred Stock may be deemed to have an anti-takeover effect and may discourage
takeover attempts not first  approved by the Board  of Directors and also  could
delay  or frustrate the removal of incumbent directors, even if such takeover or
removal would  be  beneficial  to  stockholders.  These  provisions  also  could
discourage  or make more difficult a merger, tender offer or proxy contest, even
if such  events  would be  beneficial  to  the interests  of  stockholders.  The
Delaware  General Corporation  Law imposes  restrictions upon  certain acquirors
(including their affiliates  and associates)  of 15%  or more  of the  Company's
Common  Stock. See "Management--Board of Directors  and Committees of the Board"
and "Description of Capital Stock--Preferred Stock."
 
    CERTAIN EFFECTS OF SERIES B PREFERRED  STOCK.  Following completion of  this
Offering,  the Series B Preferred Stock  will remain outstanding. The holders of
the Series B Preferred Stock are entitled to certain preferential  distributions
which  are not  available to  the holders  of Common  Stock. The  holders of the
Series B Preferred Stock are entitled to receive, out of funds legally available
therefor, cumulative dividends, calculated without compounding, equal to  $45.00
per  share per annum.  Such cumulative dividends accrue  and accumulate from the
date of issuance and are payable on March 31 of each year. Upon the liquidation,
dissolution or winding up of the Company, the holders of the Series B  Preferred
Stock  have the right, prior to any  existing or future classes of capital stock
to receive $10.0 million plus all accrued  and unpaid dividends on the Series  B
Preferred  Stock and to participate equally and  ratably with the holders of the
Common Stock in the distribution of the net assets of the Company available  for
distribution thereafter to stockholders. On or after June 25, 1998, the Company,
in its sole discretion, may redeem any or all of the Series B Preferred Stock at
a  price equal  to the original  price paid  per share, plus  accrued and unpaid
dividends. The Company  has the right  to convert the  Series B Preferred  Stock
into  Common Stock at any  time after the fifth  anniversary of issuance. If the
Company forces a conversion, the holders of the Series B Preferred Stock will be
entitled to piggy-back registration rights in connection with future  registered
offerings  of shares  of Common  Stock. To  the extent  that the  holders of the
Series B Preferred Stock receive any  distributions from the Company, the  funds
available  for distributions to the holders of the Common Stock will be reduced.
See "Description of Capital Stock -- Preferred Stock."
 
    SHARES ELIGIBLE FOR FUTURE SALE.  Future sales of Common Stock in the public
market could adversely affect the prevailing  market price of the Common  Stock.
Of the 7,403,750 shares of Common Stock outstanding following completion of this
Offering,  the 2,647,114 shares being sold hereby have been registered under the
Securities Act, and will be freely tradeable without restriction or registration
under the Securities Act, except for shares that may be acquired by "affiliates"
of the Company. The remaining 4,756,636  shares of Common Stock were issued  and
sold  by the Company  in private transactions  and may be  publicly sold only if
registered under the Securities Act or sold in accordance with an exemption from
registration such as Rule  144 under the Securities  Act. Beginning on April  6,
1997,  upon expiration of 180-day lock-up  agreements entered into in connection
with this  Offering, all  of such  shares  of restricted  Common Stock  will  be
eligible  for  sale. The  1,111,111  shares of  Common  Stock issuable  upon the
conversion of the Series B Preferred Stock (at the initial public offering price
of $9.00 per share)  will become eligible  for sale under Rule  144 on June  25,
1998,  and  392,750  shares  of  Common  Stock  issuable  upon  the  exercise of
outstanding warrants will be eligible for sale
 
                                       9
<PAGE>
under Rule 144 following  the effective date of  this Offering. In addition,  of
the  1,310,250 shares of Common Stock  issuable upon the exercise of outstanding
options, approximately 602,850 shares of  Common Stock are immediately  issuable
upon  the exercise of vested options and  will become eligible for sale, if such
options are exercised, after  the date of this  Prospectus. The holders of  such
options  have entered  into 180-day lock-up  agreements in  connection with this
Offering. Substantially all of the Company's current securities holders have the
right to include in any registration,  subject to certain restrictions, a  total
of 6,899,000 shares of Common Stock for offer and sale to the public at any time
commencing  six months after  the date of this  Prospectus. See "Shares Eligible
for Future Sale."
 
    BENEFIT OF THE OFFERING TO AFFILIATES.  Certain parties affiliated with  the
Company will receive immediate and substantial financial benefits as a result of
the  Offering.  Common  Stock  beneficially  owned  by  the  Company's executive
officers and directors and  their respective affiliates have  a market value  of
approximately  $40.2 million  based upon  the initial  public offering  price of
$9.00 per share.  In addition, Halbert  & Associates, Inc.,  a company owned  by
Messrs.  David D. Halbert and Jon S. Halbert who are also executive officers and
directors of  the Company,  will receive  proceeds from  the sale  of shares  of
Common  Stock  in  this  Offering  of  $748,000,  after  deducting  underwriting
discounts and commissions. As members of the Board of Directors of the  Company,
Messrs. D. Halbert and J. Halbert participated in the deliberations of the Board
of Directors with respect to various matters concerning the Offering. Of the net
proceeds of this Offering, approximately $7.0 million will be used to retire the
note  payable  to Whitney  Subordinated Debt  Fund, L.P.,  an affiliate  of J.H.
Whitney & Co., the largest stockholder of the Company (the "Whitney Note").  See
"Use  of  Proceeds,"  "Management," "Certain  Transactions"  and  "Principal and
Selling Stockholders."
 
    CONTROL BY  EXISTING  STOCKHOLDERS.    After  this  Offering,  officers  and
directors   of  the   Company  and   their  affiliates   will  own  beneficially
approximately 47.4%  of the  Company's outstanding  Common Stock  (approximately
45.5%  if the  Underwriters' over-allotment option  is exercised in  full). As a
result, these  stockholders may  have the  ability to  control the  Company  and
influence  its affairs  and the conduct  of its business.  Such concentration of
ownership may have the effect of  delaying, deferring or preventing a change  in
control   of  the  Company.   See  "Principal  and   Selling  Stockholders"  and
"Description of Capital Stock--Voting Agreement."
 
    IMMEDIATE AND  SUBSTANTIAL DILUTION.   Purchasers  of Common  Stock in  this
Offering  will experience  immediate and substantial  dilution in  pro forma net
tangible book value of $5.71 per share. See "Dilution."

                                  THE COMPANY
 
    The  Company was  incorporated in  Delaware in July  1993 as  a wholly owned
subsidiary of Advance Health Care, Inc. ("Advance Health Care"). Currently,  the
Company  has three  wholly owned  subsidiaries, Advance  ParadigM Mail Services,
Inc. ("Advance Mail"), Advance ParadigM Data Services, Inc. ("Advance Data") and
Advance ParadigM Clinical  Services, Inc., formerly  known as ParadigM  Pharmacy
Management, Inc. ("Advance Clinical"). Advance Mail was incorporated in 1986 and
began  operations in early 1987 as a  mail order pharmacy. In 1992, Advance Data
was incorporated  to provide  plan participants  an alternative  for  purchasing
prescriptions  through  a network  of retail  pharmacies  and to  provide claims
adjudication services. In August  1993, Advance Health  Care contributed all  of
the  capital stock of Advance Data and  Advance Mail to the Company. In December
1993, the Company acquired Advance Clinical, formerly a wholly owned  subsidiary
of  BCBS  of  Maryland, Inc.  ("BCBS  of  Maryland"). Immediately  prior  to the
Offering, Advance Health  Care will merge  with and into  the Company, with  the
Company  being  the  surviving  corporation. Immediately  prior  to  the Merger,
Advance Health  Care will  repay certain  indebtedness held  by several  of  its
stockholders  by  issuing shares  of its  common  stock to  the holders  of such
indebtedness. In addition, immediately prior to the Merger, Advance Health  Care
will  distribute to its  stockholders its assets and  liabilities, none of which
are related  to  the  business  of  the Company.  After  the  repayment  of  its
outstanding  indebtedness and the spin-off of  its other assets and liabilities,
Advance Health Care will have no  operations, or known liabilities or assets  of
its own other than its investment in the Company. The Merger will have no effect
on  the Company's financial position or results of operations and is intended to
qualify  as  a  tax  free  reorganization.  See  "Risk  Factors"  and   "Certain
Transactions  -- Merger of Advance  Health Care With and  Into the Company." The
Company's executive  offices are  located at  545 East  John Carpenter  Freeway,
Suite 1900, Irving, Texas 75062, and its phone number is (214) 830-6199.
 
                                USE OF PROCEEDS
 
    The  net proceeds to  the Company from  the sale of  the 2,000,000 shares of
Common Stock offered hereby are estimated to be $16,240,000 ($19,563,452 if  the
Underwriters  exercise  the  over-allotment  option  in  full),  after deducting
underwriting discounts and commissions  and estimated offering expenses  payable
by the Company. Of the net proceeds of this Offering, approximately $7.0 million
will  be used to retire  the Whitney Note, $2.9 million  will be used to provide
further automation  of  the  Company's  Richardson,  Texas  facility,  including
capital  improvements and equipment, and $1.8 million will be used to expand the
Company's claims processing system. The Whitney  Note was issued by the  Company
on  December 8, 1993 in the original principal amount of $7.0 million to finance
the acquisition of Advance Clinical and has  a term of seven years with a  fixed
rate  of interest of 10.1% per annum. See "Certain Transactions." The balance of
the net proceeds,  approximately $4.5  million, will  be used  to fund  possible
acquisitions  of  similar  or  complementary  businesses  and  general corporate
purposes. Although the Company has had preliminary discussions from time to time
regarding possible  acquisition opportunities,  the Company  has no  agreements,
understandings  or commitments with respect to any such opportunity, nor has the
Company allocated any portion of the net proceeds for any specific  acquisition.
There  can be  no assurance  that any  future acquisitions  will be consummated.
Pending such uses, the Company intends to invest the net proceeds in  short-term
U.S.  government securities,  high-grade commercial  paper, short-term, interest
bearing securities,  money  market funds  and  bank deposits  or  other  similar
instruments.
 
                                DIVIDEND POLICY
 
    The  Company has never declared  or paid any dividends  on its Common Stock.
The Company  currently  intends to  retain  future  earnings, if  any,  to  fund
development  and  growth of  its  business and  does  not anticipate  paying any
dividends on its Common Stock in the foreseeable future.

    The following table sets forth the capitalization of the Company at June 30,
1996, (i) on an actual basis, adjusted to reflect the 250-for-one stock split to
be effected prior  to the Offering,  (ii) on a  pro forma basis  to reflect  the
automatic  conversion of each share of Series  A Preferred Stock into 250 shares
of Common Stock and  the consummation of  the Merger, both  of which will  occur
immediately  prior to or concurrently with the closing of the Offering and (iii)
on a pro forma as adjusted basis to reflect the application of the estimated net
proceeds from the sale of the 2,000,000 shares of Common Stock offered hereby at
the initial public offering price of $9.00 per share. This table should be  read
in  conjunction  with the  Company's Consolidated  Financial Statements  and the
Notes thereto, and "Management's Discussion and Analysis of Financial  Condition

                                    DILUTION
 
    The  pro forma net tangible book value of the Common Stock of the Company as
of June 30,  1996, after giving  effect to  the 250-for-one stock  split of  the
Common Stock, the automatic conversion of the Series A Preferred Stock to Common
Stock  and the consummation of  the Merger, all of  which will occur immediately
prior to or concurrently with the  closing of this Offering, was $8,106,000,  or
$1.50  per share. "Pro forma net tangible  book value" per share of Common Stock
represents the  amount  of  the  Company's  total  tangible  assets  less  total
liabilities,  divided by the number of shares of Common Stock outstanding. After
giving effect to the sale of the 2,000,000 shares of Common Stock offered hereby
at the initial public offering price  of $9.00 per share resulting in  estimated
net  proceeds to  the Company  of approximately  $16,240,000, the  pro forma net
tangible book  value  of the  Company  as of  June  30, 1996,  would  have  been
$24,346,000,  or $3.29 per  share. This represents an  immediate increase in pro
forma net tangible book  value of $1.79 per  share to the existing  stockholders
and  an immediate dilution of $5.71 per share to new investors purchasing shares
in the Offering. The following table illustrates the per share dilution:

    The   foregoing  computations  assume  no   exercise  of  the  Underwriters'

Company's  existing stock option plans, no exercise of outstanding warrants, and
no conversion of the Series  B Preferred Stock. To  the extent such options  and
warrants  are exercised, there will be further dilution to the new investors. As
of June  30, 1996,  there were  outstanding (i)  options to  purchase  1,040,250
shares of Common Stock with a weighted average exercise price of $4.22 per share
and  (ii) warrants to  purchase 392,750 shares  of Common Stock  with a weighted

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    Advance ParadigM is a leading independent provider of PBM services to health
benefit  plan sponsors, with  over nine million health  plan members enrolled in
the Company's  programs. The  Company's  primary focus  is  on the  delivery  of
cost-effective,  high quality, integrated PBM services. In addition, the Company
has developed and  is expanding  its clinical expertise  and disease  management
services  to meet the specialized needs  of its plan members, particularly those
requiring costly, long-term and recurring therapies.
 
    The Company has  historically generated  revenues from a  number of  sources
including its mail pharmacy, its retail pharmacy network and claims adjudication
services  and its clinical  services. In addition, during  the fiscal year ended
March 31, 1996 ("fiscal year 1996"), the Company began to generate revenues from
its newly developed HBM services.
 
    The Company derives mail pharmacy revenues from the sale of  pharmaceuticals
to  members of health benefit plans  sponsored by the Company's customers. These
revenues include ingredient costs  plus a dispensing fee.  In 1992, the  Company
established  a retail pharmacy  network which currently  consists of over 46,000
retail pharmacies nationwide, and began  to provide on-line claims  adjudication
services.  The  Company records  administrative  fees as  revenues  derived from
claims adjudication services, and includes  as revenues the ingredient costs  of
the pharmaceuticals dispensed through its network. In 1993, the Company acquired
Advance  Clinical, formerly ParadigM Pharmacy  Management, Inc., a subsidiary of
BCBS of Maryland,  and began to  offer clinical services  to its customers.  The
Company's  clinical services  revenues have historically  been derived primarily
from direct rebate and volume discounts from pharmaceutical manufacturers.  Cost
of  revenues includes product  costs and other direct  costs associated with the
dispensing of  prescription drugs  through the  mail pharmacy,  retail  pharmacy
network and claims adjudication services and clinical services.
 
    The  acquisition of Advance Clinical has provided the Company with access to
large managed  care organizations  creating an  opportunity for  the Company  to
cross-sell its mail and claims processing services. In addition, the Company has
continued  to add additional managed care  accounts. In order to accommodate the
large volume and complex reporting  requirements of its managed care  customers,
the  Company acquired a highly sophisticated, state-of-the-art claims processing
system, which management believes  will accommodate volume levels  significantly
higher than those currently maintained by the Company.
 
    In  response to  the growing demand  among payors  for comprehensive disease
management programs,  the Company  recently established  its HBM  services.  The
Company  has  developed a  comprehensive health  care database,  integrating its
customers' pharmacy claims with applicable  medical and laboratory claims  data,
in  order to perform  meaningful outcomes studies  to develop disease management
programs. These programs have served as an additional source of revenue for  the
Company  in fiscal year 1996. Management believes  that the Company will be able
to cross-sell these and other services  to its existing customers, and that  HBM
services  will constitute a significantly  increased proportion of the Company's
total revenues in the future.
 
    As a  result of  its competitive  environment, the  Company is  continuously
susceptible  to margin pressures. In recent years, competing PBM providers owned
by large pharmaceutical manufacturers began aggressively pricing their  products
and  services.  This  aggressive pricing  resulted  in reduced  margins  for the
Company's traditional PBM services. While  the environment for the provision  of
traditional  services remains competitive, margins realized for the provision of
these services have stabilized in recent quarters.

this  Prospectus contains certain forward-looking  statements that involve risks
and uncertainties,  such  as  statements of  the  Company's  plans,  objectives,
expectations  and intentions. The cautionary  statements made in this Prospectus
should be read  as being  applicable to all  related forward-looking  statements
wherever  they appear  in this  Prospectus. The  Company's actual  results could
differ materially  from  those  discussed  here. Factors  that  could  cause  or

</TABLE>
 
THREE MONTHS ENDED JUNE 30, 1996 COMPARED TO THREE MONTHS ENDED JUNE 30, 1995
 
    REVENUES.   Revenues for the  three months ended June  30, 1996 increased by
$24.1 million, or 94%, compared to revenues for the three months ended June  30,
1995.  Approximately  66% of  the increase  in revenues  was attributable  to an
eight-fold increase  in  the number  of  pharmacy claims  processed  during  the
period.  Approximately 20% of the increase  was attributable to additional sales
of the Company's mail  pharmacy services, resulting from  a 44% increase in  the
number  of mail  prescriptions dispensed. Approximately  14% of  the increase in
revenues resulted from an  increase in clinical  services revenues derived  from
formulary and disease management services.
 
    COST OF REVENUES.  Cost of revenues for the three months ended June 30, 1996
increased  by $23.0 million, or  94%, compared to the  same period in 1995. This
increase was attributable primarily to the expanded volume in the Company's mail
pharmacy  and  the  additional  costs  associated  with  the  Company's   claims
processing  growth.  As  a percentage  of  revenues, cost  of  revenues remained
relatively constant at 95%.
 
    SELLING,  GENERAL  AND  ADMINSTRATIVE   EXPENSES.    Selling,  general   and
administrative  expenses for the  three months ended June  30, 1996 increased by
$272,000, or 19%, compared  to the same  period in 1995.  This increase was  the
result  of the Company's  expansion of its sales  and marketing capabilities, as
well as increases in  administrative and support staff  levels and salaries  and
benefits  in  response to  volume growth  in  all services.  As a  percentage of
revenues, selling, general and administrative expenses decreased from 6% for the
three months ended June 30, 1995 to 4% in the same period in 1996 as the  result
of greater economies of scale. The Company believes that if revenues continue to
increase  at the rate  experienced to date,  selling, general and administrative
expenses will generally decrease as a percentage of revenues in the future.
 
    INTEREST INCOME AND  INTEREST EXPENSE.   Interest expense,  net of  interest
income,  for the three months ended June 30, 1996 decreased by $168,000 compared
to the same period in 1995.  The decline resulted from cash management  programs
which  utilized the Company's short-term excess cash to generate interest income
through investment in money market funds.
 
    INCOME TAXES  (BENEFITS).   The Company  had income  tax loss  carryforwards
available  to offset income generated for the  three months ended June 30, 1996,
and as a result, incurred no federal income tax expense.
 
FISCAL YEAR 1996 COMPARED TO FISCAL YEAR 1995
 
    REVENUES.  Revenues for fiscal year 1996 increased by $34.0 million, or 37%,
compared to revenues  for the  fiscal year ended  March 31,  1995 ("fiscal  year
1995").  Approximately 39% of the increase  was attributable to additional sales
of the Company's mail  pharmacy services, resulting from  a 40% increase in  the
number  of mail  prescriptions dispensed. Approximately  40% of  the increase in
revenues was attributable to a six-fold increase in
 
                                       16
<PAGE>
the number of pharmacy  claims processed during  the fiscal year.  Approximately
21%  of the increase in revenues resulted  from an increase in clinical services
revenues derived from formulary and disease management services.
 
    COST OF REVENUES.  Cost of revenues for fiscal year 1996 increased by  $32.3
million,  or  38%,  compared  to  the  prior  fiscal  year.  This  increase  was
attributable primarily to the expanded volume in the Company's mail pharmacy and
the additional costs associated with the Company's claims processing growth.  As
a  percentage  of revenues,  cost of  revenues  remained relatively  constant at
approximately 94% for both fiscal year periods.
 
    SELLING,  GENERAL  AND  ADMINISTRATIVE  EXPENSES.    Selling,  general   and
administrative  expenses for fiscal year 1996 increased by $1.2 million, or 24%,
compared to fiscal  year 1995.  This increase was  the result  of the  Company's
expansion  of  its  sales and  marketing  activities,  as well  as  increases in
administrative and support staff levels and salaries and benefits in response to
volume growth in all services. As a percentage of revenues, selling, general and
administrative expenses  remained relatively  constant at  approximately 5%  for
both fiscal year periods.
 
    INTEREST  INCOME AND  INTEREST EXPENSE.   Interest expense,  net of interest
income, for fiscal year  1996 declined by $437,000,  or 56%, compared to  fiscal
year 1995. The decline resulted from cash management programs which utilized the
Company's  short-term excess cash to generate interest income through investment
in money market funds.
 
    INCOME TAXES (BENEFITS).  The Company  had income tax loss carryforwards  as
of  March 31, 1996 of  approximately $1.9 million, and  as a result, incurred no
federal income tax  expense. The Company  anticipates an effective  tax rate  of
approximately 39% once the tax carryforwards are fully utilized.
 
FISCAL YEAR 1995 COMPARED TO FISCAL YEAR 1994
 
    REVENUES.   Revenues  for fiscal  year 1995  increased by  $56.3 million, or
161%, compared to  revenues for the  fiscal year ended  March 31, 1994  ("fiscal
year  1994"). Approximately  51% of the  increase resulted from  the increase in
clinical services revenue  attributable to a  full year of  operations from  the
acquisition  of  Advance  Clinical,  and  increased  enrollment  of  lives under
formulary management programs. Approximately 26% of the increase in revenues was
attributable to  an 87%  increase in  the number  of pharmacy  claims  processed
during  the fiscal year. The  remaining 23% of the  increase was attributable to
additional sales of the Company's mail pharmacy services. This increase in  mail
pharmacy   revenue  resulted  from  a  68%   increase  in  the  number  of  mail
prescriptions dispensed. Revenues for fiscal  year 1994 included four months  of
Advance Clinical revenue compared with twelve months in fiscal year 1995.
 
    COST  OF REVENUES.  Cost of revenues for fiscal year 1995 increased by $52.9
million, or 162%, compared to fiscal  year 1994. This increase was  attributable
primarily  to  the expanded  volume in  the Company's  mail pharmacy  and claims
processing services, plus the additional costs associated with the inclusion  of
a  full  year of  operations  from the  acquisition  of Advance  Clinical.  As a
percentage of revenues, cost of revenues increased from 93% in fiscal year  1994
to  94% in fiscal year 1995. This increase resulted primarily from the Company's
relocation of its mail pharmacy operations from a 6,000 square foot facility  to
a  38,000 square  foot dispensing  facility in  December 1993.  In addition, the
Company expanded its  claims processing capabilities  to accommodate  additional
growth from its managed care customers.
 
    SELLING,   GENERAL  AND  ADMINISTRATIVE  EXPENSES.    Selling,  general  and
administrative expenses for fiscal year 1995 increased by $2.6 million, or 113%,
compared to fiscal  year 1994.  This increase was  the result  of the  Company's
expansion  of  its sales  and marketing  capabilities, as  well as  increases in
administrative and support staff levels and salaries and benefits in response to
volume  growth  in  all  product   and  service  areas.  Selling,  general   and
administrative expenses in fiscal year 1995 also include a full year of clinical
operations  of Advance Clinical.  As a percentage  of revenues, selling, general
and administrative  expenses decreased  from 7%  in fiscal  year 1994  to 5%  in
fiscal year 1995 as the result of greater economies of scale.
 
    INTEREST  INCOME AND  INTEREST EXPENSE.   Interest expense,  net of interest
income, for fiscal year 1995 increased  by $364,000, or 86%, compared to  fiscal
year  1994. The increase resulted from indebtedness incurred in December 1993 in
connection with the acquisition of Advance Clinical.

operations  data  for each  of the  quarters  indicated and,  in the  opinion of
management, includes  all  adjustments  (consisting  only  of  normal  recurring
adjustments)  necessary for  a fair presentation  of such data.  The Company has
experienced fluctuations  in  revenue  and operating  results  from  quarter  to
quarter  and from year to year due to a combination of factors, including demand
for the  Company's  services and  the  size,  timing of  contract  signings  and
recognition  of revenues from significant  customer additions and losses. Future
quarterly results may fluctuate, depending on these and other factors. See "Risk
Factors--Fluctuations in  Quarterly  Operating  Results;  Lengthy  Sales  Cycle;
Future  Results Uncertain." Results of operations for any particular quarter are
not necessarily indicative of results of operations for any future quarters.

LIQUIDITY AND CAPITAL RESOURCES
 
    As of March 31, 1996 and June  30, 1996, the Company had working capital  of
$316,000  and $10.4  million, respectively. The  increase in  working capital at
June 30, 1996 as compared to March 31, 1996 resulted principally from the  $10.0
million  of proceeds received by  the Company on June 25,  1996 from the sale of
its Series  B Preferred  Stock. The  Company's net  cash provided  by  operating
activities  was $1.0 million, $3.7 million and $15.7 million for the years ended
March 31, 1994, 1995 and 1996,  respectively, and $1.1 million and $127,000  for
the  three months  ended June 30,  1995 and 1996,  respectively. The significant
increases in net cash provided by operating activities were due primarily to the
timing of  receivables  and  payables resulting  from  the  Company's  continued
growth.  Cash used in  investing activities was $15.4  million, $2.2 million and
$1.6 million for the  years ended March 31,  1994, 1995 and 1996,  respectively,
and  $216,000 and $935,000  for the three  months ended June  30, 1995 and 1996,
respectively. For the year ended  March 31, 1994, the  Company used cash in  the
amount  of $14.1  million to purchase  Advance Clinical with  the remaining $1.3
million used  for purchases  of  property, plant  and  equipment. In  all  other
periods  presented, cash  used in  investing activities  was primarily  used for
purchases of property, plant and equipment associated with growth and  expansion
of  the Company's  facilities. For  the year ended  March 31,  1994, the Company
received $9.9 million from the sale of its Series A Preferred Stock and proceeds
of $6.6 million from the issuance of long term debt. For the three months  ended
June  30, 1996, the Company received $10.0 million from the sale of its Series B
Preferred Stock.  Cash  used  in financing  activities  consisted  primarily  of
scheduled debt repayments.
 
    During fiscal year 1996, the Company's continued growth resulted in net cash
provided by operating activities of $15.7 million. Historically, the Company has
been  able  to  fund  its  operations and  continued  growth  through  cash from
operations. During fiscal year  1996, the Company's  operating cash flow  funded
its  capital expenditures of  $1.6 million, and  its short term  excess cash was
invested in money market funds. The Company anticipates its capital expenditures
of approximately $4.7 million for the year ending March 31, 1997 will  primarily
consist  of additional enhancements to  the Company's claims processing systems,
and further  automation of  the  Company's mail  service facility.  The  Company
anticipates  that cash from operations, combined with the proceeds received from
the sale of the  Series B Preferred  Stock and the net  proceeds to be  received
from  the sale of the shares of  Common Stock offered hereby, will be sufficient
to meet the Company's operating
 
                                       18
<PAGE>
requirements and  expansion programs,  including  capital expenditures,  for  at
least  the next 18 months. Upon consummation  of the Offering, the Company plans
to pay off  all of  its outstanding  debt with  the exception  of capital  lease
obligations.   The  Company  anticipates  that  cash  from  operations  will  be
sufficient to meet its internal operating requirements for at least the next  18
months;  however, the Company  expects that additional funds  may be required in
the future to  successfully continue  its expansion and  acquisition plans.  The
Company may be required to raise additional funds through sales of its equity or
debt  securities or seek  financing from financial  institutions. Currently, the
Company has no borrowings  from financial institutions, and  none of its  assets
are  pledged  as collateral.  There can  be no  assurance, however,  that credit
financing will be available on  terms that are favorable  to the Company or,  if
obtained, will be sufficient for the Company's expansion needs.
 
RECENT PRONOUNCEMENTS
 
    In  October 1995, the Financial  Accounting Standards Board issued Statement
123, "Accounting  for Stock-Based  Compensation" (SFAS  123). The  Company  will
adopt  the provisions of SFAS  123 with respect to  options granted to employees
through disclosure only, effective with  the Company's fiscal year ending  March
31,  1997.  SFAS  123  also  requires that  all  stock  and  warrants  issued to
nonemployees be accounted  for based upon  the fair value  of the  consideration
received  or the fair value of the equity instruments issued. During fiscal year
1996, the Company  agreed to  issue warrants to  purchase shares  of its  Common
Stock to a customer contingent upon future expansion of member lives. As of June
30,  1996, no stock was issued and  no warrants were earned under the agreement.
In management's opinion,  the fair  value of  the warrants  at the  date of  the
agreement was not material and therefore had no material impact on the Company's
financial position or results of operations.
 
IMPACT OF INFLATION
 
    Changes   in   prices   charged  by   manufacturers   and   wholesalers  for
pharmaceuticals  dispensed  by  the  Company  affects  its  cost  of   revenues.
Historically, the Company has been able to pass the effect of such price changes
to  its customers  under the terms  of its  agreements. As a  result, changes in
pharmaceutical prices due to inflation have not adversely affected the Company.

OVERVIEW
 
    Advance ParadigM is a leading independent provider of PBM services to health
benefit plan  sponsors, based  on  the over  nine  million health  plan  members
enrolled  in  the Company's  programs.  The Company's  primary  focus is  on the
delivery of cost-effective, high quality, integrated PBM services. In  addition,
the  Company has developed  and is expanding its  clinical expertise and disease
management services  to  meet  the  specialized needs  of  its  plans'  members,
particularly  those requiring  costly, long-term and  recurring therapies. These
services are designed to inform and educate health benefit plan sponsors,  their
members   and  participating   physicians  of   nationally  recognized  practice
guidelines for  various disease  states. This  encourages physician  and  member
conformance,  improves  compliance  with  recognized  standards  and,  in  turn,
improves member health while reducing cost of care.
 
    The Company's PBM services include clinical and benefit design consultation,
formulary and rebate  administration, electronic  point-of-sale pharmacy  claims
processing,  mail  pharmacy  distribution,  pharmacy  network  management,  drug
utilization review ("DUR") and data information reporting services. The  Company
administers  a  pharmacy network  that  includes over  46,000  retail pharmacies
throughout  the   United   States.   In  1994,   in   response   to   increasing
cost-containment  pressures  from  payors,  the  Company  began  to  utilize its
clinical and  information  systems capabilities  to  develop HBM  services.  The
Company's  HBM services  include disease management,  recommendation of clinical
guidelines, patient and  physician profiling,  case finding  and compliance  and
outcome  measurement. In 1995,  the Company began marketing  its HBM services to
health benefit plan sponsors, pharmaceutical manufacturers and contract research
organizations, and as a result,  initiated programs with selected customers.  In
addition,  the  Company  intends  to  leverage  its  existing  capabilities  and
relationships by acquiring companies which  have, or are developing,  innovative
HBM  services  which  will enable  the  Company  to provide  a  centralized care
management alternative for its customers.
 
    The Company was  incorporated in  Delaware in July  1993 as  a wholly  owned
subsidiary of Advance Health Care. Currently, the Company has three wholly owned
subsidiaries,  Advance Mail, Advance Data and Advance Clinical. Advance Mail was
incorporated in  1986  and  began operations  in  early  1987 as  a  mail  order
pharmacy. In 1992, Advance Data was incorporated to provide plan participants an
alternative  for purchasing prescriptions through a network of retail pharmacies
and to provide claims adjudication services. In August 1993, Advance Health Care
contributed all of the  capital stock of  Advance Data and  Advance Mail to  the
Company.  In December  1993, the Company  acquired Advance  Clinical, formerly a
wholly owned subsidiary of BCBS of Maryland. See "The Company."
 
INDUSTRY BACKGROUND
 
    In response to escalating health care costs, cost containment efforts in the
health care industry  have led to  rapid growth in  managed care. Despite  these
efforts,  continued advances in medical technology and new drug development have
led to significant increases in drug  utilization and related costs, creating  a
need  for more efficient, cost effective  drug delivery mechanisms. PBM services
evolved  to  address  this  need.  Through  volume  discounts,  retail  pharmacy
networks,  mail pharmacy  services, formulary  administration, claims processing
and DUR, PBMs created an opportunity for health benefit plan sponsors to deliver
drugs to  their  members in  a  cost-effective manner  while  improving  patient
compliance  with recommended guidelines.  It is currently  estimated that annual
outpatient pharmaceutical  expenditures account  for  approximately 7%,  or  $70
billion,   of  the  $1  trillion  health   care  market,  and  that  third-party
prescriptions managed by PBMs represent a steadily increasing proportion of this
amount.
 
    Traditionally, PBMs focused primarily on cost containment by (i)  generating
volume  rebates from pharmaceutical companies,  (ii) encouraging substitution of
generics for branded medications and (iii) obtaining price discounts through the
retail pharmacy network and mail distribution.  Over the last several years,  in
response  to increasing payor  demand, PBMs have  begun to develop sophisticated
formulary management capabilities and  comprehensive, on-line customer  decision
support  tools in an  attempt to better  manage the delivery  of health care and
ultimately costs. Simultaneously,  health benefit  plan sponsors  have begun  to
focus  on the quality and efficiency of care, emphasizing disease prevention, or
wellness, and care management. There is rapidly growing
 
                                       20
<PAGE>
demand among  payors  for  comprehensive disease  management  programs  as  cost
containment  becomes  more dependent  on improvements  in  the quality  of care.
According to industry sources,  approximately 77% of  large employers said  they
would  likely adopt some  form of disease  management program over  the next two
years. HBM services are being developed  to address this demand through the  use
of  traditional PBM services combined  with clinical expertise and sophisticated
information systems.
 
THE ADVANCE PARADIGM SOLUTION
 
    As a leading independent PBM, the Company provides benefit design, formulary
and  rebate  administration,  point-of-sale  pharmacy  claims  processing,  mail
pharmacy,  pharmacy  network  management,  DUR  and  data  information reporting
services. The Company  believes its clinical  expertise and information  systems
combined  with its PBM services provide the Company with a competitive advantage
in the evolving market for HBM  services. Through its HBM services, the  Company
utilizes  its expertise  in development  of formulary  designs, recommends "best
practices" guidelines, and has created patient and physician profiling, clinical
intervention strategies and proprietary  case finding techniques. The  Company's
proprietary  decision support  systems provide  a platform  for the  delivery of
outcomes-based HBM services. As  part of its HBM  services, which integrate  the
Company's decision support systems with its core clinical expertise, the Company
currently provides disease management programs that address cardiovascular risk,
congestive  heart  failure  and  diabetes,  and  has  under  development disease
management programs which address asthma, dyspepsia and otitis media (middle ear
infection).
 
STRATEGY
 
    The Company's mission is  to improve the quality  of care delivered to  plan
members  while assisting plan sponsors in reducing overall health benefit costs.
The Company's strategy is to maintain its position as a leading provider of  PBM
services  and expand its presence as a provider of HBM services. Key elements of
this strategy include:
 
    EXPAND CORE PBM CUSTOMER BASE.   The Company believes that it will  continue
to benefit from growth in the PBM market. From 1994 to 1996, the number of lives
for  which the  Company provided PBM  services increased  from approximately 3.7
million to 9.0 million. Of the  nine million lives, the Company provides  rebate
contracting  services for  approximately two  million lives  on behalf  of other
PBMs. The Company intends to expand its market share by focusing on larger, more
sophisticated customers,  such as  Blue Cross  and Blue  Shield ("BCBS")  plans,
insurance companies and large employer groups.
 
    EXPAND  HBM  SERVICES.    The Company  believes  that  HBM  services provide
significant opportunities  for  future  growth.  As a  result,  the  Company  is
presently  integrating its  PBM services,  information systems  and medical care
guidelines to create comprehensive  HBM programs. The  Company believes that  it
can  cross-sell HBM  services to  its existing  customer base.  In addition, the
Company intends  to  leverage its  existing  capabilities and  relationships  by
acquiring  companies which have,  or are developing,  innovative HBM services in
order to provide a centralized, care management alternative for its customers.
 
    PURSUE STRATEGIC ACQUISITIONS.   The  Company intends  to continue  pursuing
acquisition  opportunities to expand the scope  of its services and increase its
market share. For example, in December  1993, the Company complemented its  mail
service  and retail network pharmacy management services with the acquisition of
ParadigM  Pharmacy  Management  Inc.,  a  provider  of  sophisticated  formulary
management  services.  Due  to increasing  competition  within the  PBM  and HBM
services markets, the Company believes that there are significant  opportunities
to  acquire or consolidate businesses that  will complement its existing service
offerings and allow it to realize additional economies of scale.
 
    ESTABLISH STRATEGIC RELATIONSHIPS.  The Company has successfully established
strategic relationships  with  certain pharmaceutical  manufacturers  and  major
customers.  In its strategic relationships  with drug manufacturers, the Company
strives to create collaborative relationships  whereby the Company provides  the
manufacturers with consulting and related services that permit the manufacturers
to  benefit from the Company's expertise  in disease management and pharmacy and
medical claims data analysis, while the Company benefits from the marketing  and
financial  resources of the  manufacturers. In its  strategic relationships with
certain major customers, the  customers assume equity  positions in the  Company
which fosters the development of long-term
 
                                       21
<PAGE>
strategic   alliances.   To  date,   the   Company  has   established  strategic
collaborative relationships  with five  pharmaceutical companies  and  strategic
customer  alliances with BCBS  of Maryland, BCBS  of Texas and  VHA Inc. and has
entered into a letter of  intent to enter into  such an alliance with  Principal
Health Care, Inc.
 
SERVICES
 
    PHARMACEUTICAL  BENEFIT  MANAGEMENT.   The  Company's  PBM  services include
clinical and benefit design  consultation, formulary and rebate  administration,
electronic point-of-sale pharmacy claims processing, mail pharmacy distribution,
pharmacy  network management,  DUR and  data information  reporting. The Company
administers a  pharmacy network  which includes  over 46,000  retail  pharmacies
throughout  the United  States. The Company  currently provides  PBM services to
over 200 health plan  benefit sponsors covering over  nine million plan  members
enrolled  in the Company's programs,  which includes rebate contracting services
for approximately two million lives on  behalf of other PBMs. The Company's  PBM
services are divided among three divisions: Clinical Services, Data Services and
Mail Pharmacy Services.
 
    CLINICAL  SERVICES.  The Company develops and implements customized programs
of clinical and formulary management services to reduce drug benefit costs while
promoting clinically appropriate drug usage. The Company works closely with each
customer to determine  the desired  features of a  benefit plan,  such as  which
drugs  are covered,  extent of generic  substitution and  co-payment levels. The
Company also develops customized formularies which recommend the most clinically
appropriate, cost-effective drugs to be prescribed. Formularies are listings  of
drugs  and treatment protocols to be  followed by the prescribing physician that
are intended to reduce the costs of prescription drugs under a particular health
plan.  Formularies  reduce  cost  through  the  use  of  generic   substitution,
therapeutic substitution and other techniques and may also generate leverage for
the  Company to negotiate more favorable rebates and other volume discounts from
drug manufacturers.
 
    Formulary compliance can be encouraged by  (i) plan design features such  as
tiered  co-payments, which  require the  member to pay  a higher  amount for the
non-preferred drug, (ii) prescriber education  programs in which the Company  or
the  managed care  customer actively seek  to educate the  prescribers about the
formulary preferences and  (iii) therapeutic substitution  programs that  target
certain  high-cost therapies for concentrated  formulary compliance efforts. The
Company continually  monitors  the  efficacy  and  therapeutic  applications  of
pharmaceutical  products, the availability of  new drugs and generic substitutes
and rebate and other pricing  arrangements with drug manufacturers. The  Company
works  closely with each customer to develop a customized formulary based on the
customer's drug utilization patterns and member and physician populations.
 
    The Company  employs several  intervention strategies  to promote  formulary
compliance  by altering physician prescribing patterns. The Company utilizes its
decision support software to analyze data  and present reports to plan  sponsors
or physicians that compare a physician's formulary compliance against his or her
peers  in the  plan. The Company  provides proprietary  educational materials to
plan physicians, pharmacists or  the plan sponsor  to promote general  education
and formulary compliance.
 
    DATA   SERVICES.    The   Company's  retail  pharmacy   network  and  claims
adjudication services  provide  plan  sponsors an  efficient,  automated  claims
processing  network that permits point-of-sale adjudication and data collection.
The Company  administers a  network of  approximately 46,000  retail  pharmacies
which  are preferred providers of prescription  drugs to members of the pharmacy
benefit plans managed  by the  Company (the "Advance  Pharmacies"). The  Advance
Pharmacies  have agreed  to accept  payments at  predetermined negotiated rates,
which the Company believes  to be generally more  favorable than typical  retail
prices.  The Company's claims adjudication services division is its most rapidly
growing  division  with   the  number  of   claims  processed  increasing   from
approximately  816,000 claims  in fiscal  year 1994  to over  9.3 million claims
processed in fiscal  year 1996, with  over 5.1 million  claims processed in  the
quarter ended June 30, 1996.
 
    The  Advance Pharmacies  are linked  to the  Company's Advance Rx-Registered
Trademark- on-line  claims adjudication  and processing  system, which  contains
patient  medication history, plan  enrollment and eligibility  data. The Advance
Rx-Registered Trademark- on-line system provides pharmacists with  point-of-sale
information   including  plan  design,  drugs   covered,  negotiated  price  and
co-payment requirements,  as  well  as  extensive  drug  utilization  evaluation
capabilities.  The  Advance  Rx-Registered  Trademark-  system  performs on-line
concurrent  drug  utilization  evaluation  at   the  point  of  sale   including
 
                                       22
<PAGE>
verification   of  eligibility,  and  identifies  potential  drug  interactions,
frequency  of  refills  and  other  matters.  Within  seconds  of  submitting  a
prescription  to  the Advance  Rx-Registered  Trademark- system,  the pharmacist
receives a computerized message as to whether the prescription will be  accepted
by  the Company for payment.  In addition, the Company  can alert the pharmacist
that the prescribed drug is not  the preferred formulary drug, that  therapeutic
or generic substitution opportunities are available, or as to the need to comply
with prior authorization programs.
 
    MAIL  PHARMACY SERVICES.   The Company's mail  pharmacy services enable plan
sponsors to  realize  further cost  savings  on maintenance  medications,  while
benefiting  from the Company's automated claims adjudication and data collection
capabilities. Cost savings to plan  sponsors result from promotion of  formulary
compliance  by  the  Company's in-house  pharmacy,  and price  discounts  to the
Company from  volume purchases.  The  mail pharmacy  typically dispenses  up  to
100-day  supplies  of  medications  for  chronic  conditions,  thereby  reducing
repetitive dispensing fees. The Company believes that its mail pharmacy services
reduce costs to plan  sponsors because the Company's  role as pharmacist  allows
for  direct enforcement of the  formulary, generic and therapeutic substitution,
volume purchasing  discounts,  and  lower dispensing  fees  than  are  typically
available through retail pharmacies. In addition, the Company's control over the
dispensing  process permits it to ensure  that formulary compliance programs are
followed, to perform DUR  on each prescription and  to reduce the potential  for
submission  of fraudulent,  incorrect or  ineligible claims.  Plan sponsors also
benefit  from  the  drug  utilization  review  capabilities  of  the   Company's
management  information system,  which assist  in preventing  potential abuse by
plan participants  and help  identify  areas to  be  targeted for  further  cost
reductions.
 
    The  Company's  mail service  pharmacy  is located  in  approximately 38,000
square feet  of  leased  space  in Richardson,  Texas  and  currently  dispenses
approximately 13,000 prescriptions per week. The mail service dispensing process
is  highly automated,  featuring bar code  and scanning technology  to route and
track orders, computerized dispensing of many medications and computer-generated
mailing labels and invoices. To ensure accurate dispensing of prescriptions, the
mail service system  is equipped  with automated quality  control features,  and
each prescription is inspected by a registered pharmacist.
 
    HEALTH  BENEFIT  MANAGEMENT.   The  Company's HBM  services  include disease
management,  recommendation  of  clinical  guidelines,  patient  and   physician
profiling, case finding and compliance and outcomes measurement. The Company has
developed  disease management programs  covering cardiovascular risk, congestive
heart failure and diabetes and has under development disease management programs
which address asthma, dyspepsia and otitis media. By analyzing patients' medical
and pharmacy  claim patterns,  the Company  can assist  payors and  health  care
providers  in the early identification of  patients whose care might be improved
through additional or alternative treatment or medication.
 
    The Company's  disease management  programs incorporate  clinical  protocols
based  on specific  medical treatments and  "best treatment  practices" from the
medical community. These protocols are represented as a series of algorithms  or
rules  contained in the Company's decision support systems. These algorithms are
updated continually by the Company  based upon changes in nationally  recognized
best  treatment  practices, clinical  experience and  review of  current medical
literature.
 
    Upon identifying an "at-risk" patient, the Company, working closely with the
medical staff of its customer, recommends treatment protocols for the identified
disease. The Company's staff monitors  the identified patient's compliance  with
the  suggested program, including prescription usage.  If it appears, based upon
the staff's analysis of the  patient's treatment, that the recommended  protocol
is  not being applied, the Company's staff will coordinate with its customers to
initiate direct  telephone contact  with the  patient or  physician,  suggesting
additional treatment or testing.
 
    In  addition  to  identifying  targeted  patients  for  the  physician,  the
Company's case-finding algorithms are also  designed to recognize trends in  the
treatments  and drugs  prescribed by health  care providers. Once  a provider is
identified through  the  algorithm, the  Company's  staff prepares  a  physician
journal   letter  communicating  the  recommended  clinical  protocols  for  the
treatment of the identified disease.  Physician performance and compliance  with
the  recommended  protocols  are monitored  utilizing  the  Company's integrated
health care  database,  and  additional communications  such  as  "dear  doctor"
letters and physician report cards are sent to physicians who would benefit from
intervention  strategies.  The Company  has  found physician  response  to these
 
                                       23
<PAGE>
materials to be positive. In  general, the physicians appreciate the  comparison
of  their treatment activities to  the latest practices in  the treatment of the
targeted disease. This "clinical credibility" allows the Company's customers  to
more ably influence physician treatment patterns.
 
    DECISION  SUPPORT SYSTEMS.  In connection  with the monitoring, analysis and
evaluation of drug  utilization for  its PBM  customers and  following years  of
development,  the Company  introduced proprietary decision  support systems. The
Company's extensive database  repository incorporates a  series of  interrelated
databases  consisting of patient profiles, provider profiles, payor information,
and medical and pharmacy dictionaries  of diagnosis codes, treatment codes,  and
prescription drug information. One of the Company's proprietary decision support
systems,  ApotheQuery-Registered  Trademark-,  enables the  Company  to identify
cost-saving opportunities arising from the possible overuse or inappropriate use
of drugs, the use of high cost drugs and the use of drugs not on the  formulary.
ApotheQuery-Registered Trademark- organizes and analyzes data by drug, physician
specialty  and/or various other criteria, or a combination of criteria, enabling
the Company to  identify patient  populations and physicians  who would  benefit
from  intervention strategies and measures  the effectiveness of such strategies
through outcomes and utilization review. The Company's decision support  systems
have  been  developed  using  commercially  available  technology  and  are  not
protected by  any patents.  The Company  protects its  decision support  systems
through physical security measures as well as access security procedures.
 
    In  1994, the Company began to integrate its customers' pharmacy claims with
applicable  medical  and  laboratory  claims  and  patient  survey  data,   when
available.  This integrated health care database complements the capabilities of
ApotheQuery-Registered Trademark-  by including  data points  for diagnosis  and
treatment  codes.  This  integrated health  care  database  facilitates querying
capability for not only pharmacy data but integrated pharmacy, medical, and  lab
data  as well.  This allows  the Company and  its customers  to identify problem
areas for the health  plan and implement timely  clinical solutions. It  further
enhances  the Company's ability  to complete meaningful  outcomes studies and to
develop effective disease management programs.  The Company's medical staff  has
incorporated   algorithms  based   on  nationally   recognized  "best  practice"
guidelines for chronic and acute  diseases into its proprietary databases.  This
integrated  health  care database  integrates medical,  lab and  pharmacy claims
data, and  allows  the  Company  to  perform  sophisticated  outcomes  analysis,
detailed   physician  and  pharmacy  provider   profiling  and  utilization  and
formulary/rebate analysis.
 
CUSTOMERS
 
    The Company currently provides PBM services for over 200 health plan benefit
sponsors covering  over nine  million  plan members  enrolled in  the  Company's
programs,  which  includes  rebate contracting  services  for  approximately two

STRATEGIC ALLIANCES
 
    The  Company  has  successfully  established  strategic  relationships  with
certain large pharmaceutical manufacturers and major customers. In its strategic
relationships   with  drug   manufacturers,  the   Company  strives   to  create
collaborative relationships whereby the Company provides the manufacturers  with
products  and  services  that  permit  the  manufacturers  to  benefit  from the
Company's expertise in disease management  and pharmacy and medical claims  data
analysis,  while the Company benefits from the marketing and financial resources
of the manufacturers. Through  this type of  relationship, the Company  licenses
selected  disease management  programs to  the manufacturers  and provides other
related  services.   In  its   strategic   relationships  with   certain   major
 
                                       24
<PAGE>
customers,  the customers assume equity positions  in the Company, which fosters
the development of  long-term strategic alliances.  This arrangement allows  for
increased  information flow between the Company  and customers to facilitate the
progressive development of solutions to meet  the customers' unique PBM and  HBM
service  needs.  To date,  the Company  has established  strategic collaborative
relationships  with  five  pharmaceutical   companies  and  strategic   customer
alliances with BCBS of Maryland and BCBS of Texas, and has entered into a letter
of  intent to enter into  such an alliance with  Principal Health Care, Inc. The
Company is  implementing its  cardiovascular risk  reduction disease  management
program  on behalf of  BCBS of Maryland and  George Washington University Health
Plan. The  Company  has also  licensed  several  of these  programs  to  certain
pharmaceutical companies. See "Certain Transactions."
 
SALES, MARKETING AND CUSTOMER SERVICE
 
    The  Company markets  and sells  its services  through a  direct sales force
consisting of  four  national sales  and  marketing representatives  located  in
Baltimore,    Cleveland,   Minneapolis   and   Dallas.   Sales   and   marketing
representatives are supported by a staff of customer service representatives  in
the  Company's  facilities  located  in  the  Baltimore  and  Dallas  areas. The
Company's proposal development group and marketing staff also work closely  with
the  sales representatives. The  typical sales cycle  takes approximately six to
nine months.
 
    The Company offers a toll-free telephone line staffed with trained  customer
service  representatives and pharmacists 14 hours  each day and on-call 24 hours
each day. The  Company continually  monitors the  member service  phone desk  to
ensure that incoming calls from members are answered in a timely and appropriate
manner.  Further,  the  Company  monitors  the  quality  standards  of  its mail
services, including  the  dispensing of  prescription  orders through  the  mail
within two business days of receipt under ordinary circumstances.
 
COMPETITION
 
    The  Company competes with a number of larger, national companies, including
Caremark  International  Inc.,  Diversified  Pharmaceutical  Services,  Inc.  (a
subsidiary  of  SmithKline Beecham  Corporation),  Express Scripts,  Inc., Merck
Medco Managed  Care, Inc.,  (a subsidiary  of  Merck &  Co., Inc.),  PCS  Health
Systems,  Inc. (a  subsidiary of  Eli Lilly &  Company), and  Value Health, Inc.
(which  recently  announced  a  50-50  joint  venture  with  Baxter   Healthcare
Corporation).  These competitors are  significantly larger than  the Company and
possess greater financial, marketing  and other resources  than the Company.  To
the  extent that competitors are owned by pharmaceutical manufacturers, they may
have  pricing  advantages  that  are  unavailable  to  the  Company  and   other
independent PBMs.
 
    The Company believes that the primary competitive factors in the PBM and HBM
industries  include:  independence  from  drug  manufacturers  and  payors;  the
quality,  scope  and  costs  of  products  and  services  offered  to  insurance
companies,  HMOs, employers and other sponsors  of health benefit plans and plan
participants; responsiveness  to customers'  demands; the  ability to  negotiate
favorable  rebate and volume  discounts from drug  manufacturers; the ability to
identify and  apply  effective  cost  containment  programs  utilizing  clinical
strategies;  the ability to  develop formularies; the ability  to market PBM and
HBM services to  health benefit plan  sponsors; a strong  managed care  customer
base  which  supports the  development  of HBM  products  and services;  and the
commitment to providing flexible, clinically oriented services to customers. The
Company believes that  its larger competitors  offer comprehensive PBM  services
and  some form of HBM services.  The Company considers its principal competitive
advantages to be  its independence  from drug manufacturers  and payors,  strong
managed  care customer base which supports  the development of HBM services, and
commitment to providing flexible, clinically oriented services to its customers.
 
LIABILITY INSURANCE
 
    Certain aspects of  the Company's  operations, including  the dispensing  of
pharmaceuticals,  may  subject  the  Company to  claims  for  personal injuries,
including those resulting from dispensing errors, package tampering and  product
defects.  The Company carries the types  of insurance customary in its industry,
including professional liability  and general and  product liability  insurance.
The  Company believes that its insurance  protection is adequate for its present
business  operations.  Although  pharmacies  in   general  have  not,  as   yet,
experienced any unusual difficulty in obtaining insurance at an affordable cost,
there can be no assurance that the Company will be able to maintain its coverage
at  acceptable costs  in the  future or,  if it  does, that  the amount  of such
coverage would be sufficient to cover all potential claims.
 
                                       25
<PAGE>
GOVERNMENT REGULATION
 
    Various aspects  of the  Company's businesses  are governed  by federal  and
state   laws  and  regulations  and  compliance  is  a  significant  operational
requirement for the  Company. The  Company believes  that it  is in  substantial
compliance with all existing legal requirements material to the operation of its
business.
 
    Certain federal and related state laws and regulations affect aspects of the
Company's pharmacy benefit management business. Among these are the following:
 
    FDA REGULATION.  The U.S. Food and Drug Administration ("FDA") generally has
authority to regulate drug promotional materials that are disseminated "by or on
behalf  of"  a drug  manufacturer. In  October  1995, the  FDA held  hearings to
determine whether and to what extent  the activities of PBM companies should  be
subject  to FDA  regulation. At  this hearing,  FDA officials  expressed concern
about the efforts  of PBMs that  are owned  by drug manufacturers  to engage  in
therapeutic  switching programs  and about the  criteria used by  such PBMs that
govern the inclusion and exclusion of particular drugs in formularies.  Although
the  FDA has not published any proposed rules to date on the regulation of PBMs,
there can be  no assurance that  the FDA  will not seek  to increase  regulation
pertaining to the PBM industry, including with respect to companies that are not
owned by drug manufacturers.
 
    ANTI-REMUNERATION  LAWS.  Medicare  and Medicaid law  prohibits, among other
things, an entity from  paying or receiving, subject  to certain exceptions  and
"safe  harbors," any remuneration to induce the referral of Medicare or Medicaid
beneficiaries or  the purchase  (or the  arranging for  or recommending  of  the
purchase)  of items or  services for which  payment may be  made under Medicare,
Medicaid or other  federally-funded health  care programs.  Several states  also
have  similar  laws which  are not  limited  to services  for which  Medicare or
Medicaid payment  may  be made.  State  laws  vary and  have  been  infrequently
interpreted  by  courts or  regulatory agencies.  Sanctions for  violating these
federal and state anti-remuneration laws may include imprisonment, criminal  and
civil  fines,  and exclusion  from participation  in  the Medicare  and Medicaid
programs.
 
    The federal statute has  been interpreted broadly by  courts, the Office  of
Inspector  General ("OIG")  within the Department  of Health  and Human Services
("HHS"), and  administrative  bodies. Because  of  the federal  statute's  broad
scope, federal regulations establish certain "safe harbors" from liability. Safe
harbors  exist for  certain properly  reported discounts  received from vendors,
certain investment interests,  and certain properly  disclosed payments made  by
vendors  to group purchasing organizations. A practice that does not fall within
a safe harbor is not  necessarily unlawful, but may  be subject to scrutiny  and
challenge. In the absence of an applicable statutory exception or safe harbor, a
violation of the statute may occur even if only one of the purposes of a payment
arrangement  is to  induce patient referrals  or purchases.  Among the practices
that have been identified by the  OIG as potentially improper under the  statute
are  certain "product conversion  programs" in which benefits  are given by drug
manufacturers to  pharmacists  or physicians  for  changing a  prescription  (or
recommending  or requesting such a  change) from one drug  to another. Such laws
have been cited  as a partial  basis, along with  the state consumer  protection
laws discussed below, for investigations and multi-state settlements relating to
financial  incentives provided  by drug  manufacturers to  retail pharmacists in
connection with such programs.
 
    To the  Company's  knowledge, these  anti-remuneration  laws have  not  been
applied  to  prohibit PBMs  from receiving  amounts  from drug  manufacturers in
connection  with  drug   purchasing  and  formulary   management  programs,   to
therapeutic  substitution  programs conducted  by  independent PBMs,  or  to the
contractual relationships such  as those  the Company  has with  certain of  its
customers.  The Company believes  that it is in  substantial compliance with the
legal requirements  imposed  by  such  laws and  regulations,  and  the  Company
believes  that there  are material  differences between  drug-switching programs
that have  been challenged  under these  laws and  the programs  offered by  the
Company  to its customers. However,  there can be no  assurance that the Company
will not be subject to scrutiny or challenge under such laws and regulations, or
that any  such challenge  would not  have  a material  adverse effect  upon  the
Company.
 
    OIG  STUDY.   The OIG  Office of  Evaluation and  Inspections (which  is not
responsible for  investigations  of potential  violations  of  anti-remuneration
laws,   but  which  seeks  to  improve   the  effectiveness  and  efficiency  of
 
                                       26
<PAGE>
HHS programs) currently is conducting  a study of PBM arrangements  particularly
with  regard to  the concerns and  implications for  Medicaid beneficiaries. The
Company cannot predict the outcome of the study or the impact, if any, that such
study might have on its business.
 
    ERISA REGULATION.   The  Employee  Retirement Income  Security Act  of  1974
("ERISA")  regulates  certain aspects  of  employee pension  and  health benefit
plans, including self-funded corporate health  plans with which the Company  has
agreements  to provide  PBM services.  There can be  no assurance  that the U.S.
Department of Labor, which is the  agency that enforces ERISA, would not  assert
that  the fiduciary obligations imposed by  the statute apply to certain aspects
of the Company's operations.
 
    CONSUMER PROTECTION LAWS.   Most states have  consumer protection laws  that
have  been the basis for investigations  and multi-state settlements relating to
financial incentives  provided by  drug manufacturers  to retail  pharmacies  in
connection  with drug switching programs. In  addition, pursuant to a settlement
agreement entered into with 17 states  on October 25, 1995, Merck Medco  Managed
Care,  Inc. ("Medco"), the PBM subsidiary of pharmaceutical manufacturer Merck &
Co., agreed to require pharmacists affiliated with Medco mail service pharmacies
to disclose to physicians and patients the financial relationships between Merck
& Co.,  Medco  and the  mail  service  pharmacy when  such  pharmacists  contact
physicians  seeking  to change  a  prescription from  one  drug to  another. The
Company believes that its contractual relationships with drug manufacturers  and
retail  pharmacies do not  include the features that  were viewed by enforcement
authorities as problematic in these settlement agreements. However, no assurance
can be given that the Company will not be subject to scrutiny or challenge under
one or more of these laws.
 
    NETWORK ACCESS LEGISLATION.  A majority of states have adopted some form  of
legislation  affecting the  ability of the  Company to limit  access to pharmacy
provider networks  or  from removing  network  providers. Such  legislation  may
require  the Company or  its customers to  admit any retail  pharmacy willing to
meet  the  plan's  price  and  other  terms  for  network  participation;   this
legislation  is sometimes referred to as "any willing provider" legislation. The
Company  has  not  been  materially  affected  by  these  statutes  because   it
administers  a large network of over 46,000 retail pharmacies and will admit any
licensed pharmacy that  meets the Company's  credentialling criteria,  involving
such matters as adequate insurance coverage, minimum hours of operation, and the
absence of disciplinary actions by the relevant state agencies.
 
    LEGISLATION IMPOSING PLAN DESIGN RESTRICTIONS.  Some states have legislation
that  prohibits the  plan sponsor  from implementing  certain restrictive design
features. For example, some states provide that  members of the plan may not  be
required  to use network providers, but must also be provided with benefits even
if they  choose to  use  non-network providers;  this legislation  is  sometimes
referred to as "freedom of choice" legislation. Other states mandate coverage of
certain benefits or conditions. Such legislation does not generally apply to the
Company, but it may apply to certain of the Company's customers such as HMOs and
insurers.  If such legislation were to become  widespread and broad in scope, it
could have  the effect  of  limiting the  economic benefits  achievable  through
pharmacy benefit management.
 
    LICENSURE  LAWS.  Many states have  licensure or registration laws governing
certain types of ancillary health care organizations, including PPOs, TPAs,  and
companies  that provide  utilization review  services. The  scope of  these laws
differs significantly from state to state,  and the application of such laws  to
the  activities of pharmacy  benefit managers is often  unclear. The Company has
registered under such laws in those  states in which the Company has  concluded,
after  discussion with the  appropriate state agency,  that such registration is
required.
 
    LEGISLATION AFFECTING DRUG PRICES.   In the past,  some states have  adopted
legislation  providing  that a  pharmacy participating  in the  state's Medicaid
program must give the state the best price that the pharmacy makes available  to
any third party plan; this legislation is sometimes referred to as "most favored
nation"  legislation. Such legislation,  if enacted in  any state, may adversely
affect the Company's ability to negotiate  discounts in the future from  network
pharmacies.  Other  states  have enacted  "unitary  pricing"  legislation, which
mandates that all wholesale purchasers of drugs within the state be given access
to the same discounts and incentives.
 
                                       27
<PAGE>
    REGULATION OF FINANCIAL RISK PLANS.  Fee-for-service prescription drug plans
are not generally subject to financial regulation by the states. However, if the
PBM offers  to  provide prescription  drug  coverage  on a  capitated  basis  or
otherwise  accepts material  financial risk  in providing  the benefit,  laws in
various states may regulate the  plan. Such laws may  require that the party  at
risk  establish reserves or otherwise demonstrate financial responsibility. Laws
that may apply in such cases include insurance laws, HMO laws or limited prepaid
health service plan laws. Many of these state laws may be preempted in whole  or
in  part  by  ERISA,  which provides  for  comprehensive  federal  regulation of
employee benefit plans. However, the scope of ERISA preemption is uncertain  and
is  subject to  conflicting court  rulings. Other state  laws may  be invalid in
whole or  in  part  as  an  unconstitutional attempt  by  a  state  to  regulate
interstate  commerce, but the outcome of challenges  to these laws on this basis
is uncertain.  Accordingly, compliance  with  state laws  and regulations  is  a
significant operational requirement for the Company.
 
    MAIL PHARMACY REGULATION.  The Company's mail service pharmacy is located in
Richardson,  Texas and the Company  is licensed to do  business as a pharmacy in
Texas. Many of the states into  which the Company delivers pharmaceuticals  have
laws  and  regulations  that  require out-of-state  mail  service  pharmacies to
register with the  board of pharmacy  or similar regulatory  body in the  state.
These  states generally permit the  mail service pharmacy to  follow the laws of
the state within  which the mail  service pharmacy is  located. The Company  has
registered   in  every  state  in  which,   to  the  Company's  knowledge,  such
registration is required. In addition, various pharmacy associations and  boards
of  pharmacy  have  promoted  enactment  of  laws  and  regulations  directed at
restricting or prohibiting the operation of out-of-state mail service pharmacies
by, among other  things, requiring compliance  with all laws  of certain  states
into  which the mail service pharmacy dispenses medications whether or not those
laws conflict with the laws  of the state in which  the pharmacy is located.  To
the  extent that  such laws  or regulations  are found  to be  applicable to the
Company, the Company would be required to comply with them.
 
    Other statutes and regulations impact the Company's mail service operations.
Federal statutes and regulations govern the labeling, packaging, advertising and
adulteration of prescription drugs and the dispensing of controlled  substances.
The  Federal Trade Commission requires mail  order sellers of goods generally to
engage in truthful advertising, to stock  a reasonable supply of the product  to
be  sold, to fill mail orders within  thirty days, and to provide customers with
refunds when  appropriate.  The  United  States  Postal  Service  has  statutory
authority  to restrict the transmission of  drugs and medicines through the mail
to a degree  that could have  an adverse  effect on the  Company's mail  service
operations.  The U.S. Postal Service has exercised such statutory authority only
with respect  to  controlled  substances.  Alternative  means  of  delivery  are
available to the Company.
 
EMPLOYEES
 
    As  of August 31, 1996, the Company had 312 employees. None of the employees
are represented by a  labor union. In the  opinion of management, the  Company's
relationship with its employees is good.
 
FACILITIES
 
    The  Company's  corporate headquarters  are  located in  approximately 8,000
square feet of leased  space in Irving, Texas.  This lease expires November  30,
1997.  The Company's clinical division is located in approximately 11,600 square
feet of leased space in Hunt Valley, Maryland. This lease expires March 31, 1999
with an option  to renew for  an additional five-year  term. The Company's  data
services division is located in approximately 23,000 square feet of leased space
in  Dallas,  Texas. This  lease expires  November 30,  1999. The  Company's mail
service pharmacy is located in approximately 38,000 square feet of leased  space
in  Richardson, Texas. This lease expires May 31, 2001 and has a five-year fixed
rate renewal option and an option to purchase at any time during the term of the
lease. See Note 6 of Notes to Consolidated Financial Statements.

(1) Upon the occurrence of the following events, the vesting of the options will
    accelerate: (i) as to the options held by Messrs. D. Halbert and J. Halbert,
    upon the consummation of  any transaction in which  an outside entity  gains
    more  than 50% ownership  of the Company, the  options will vest immediately
    prior to such transaction and  (ii) as to the  options held by Dr.  Filipek,
    Mr.  Sattler and Dr. Wright, upon a  sale of substantially all of the Common
    Stock or assets of the Company or a  merger in which the Company is not  the
    surviving   entity,  the  options  will   vest  immediately  prior  to  such
    transaction.
 
(2) The value of the  options is based upon  the difference between the  assumed
    market value of $9.00 per share, which is the initial public offering price,
    and the exercise price.

STOCK OPTION PLANS
 
    On July 30, 1993, the Board of Directors and the stockholders of the Company
adopted the 1993 Incentive Stock Option Plan (the "Plan") which provides for the
grant of qualified stock options to  officers and key employees of the  Company.
The purpose of the Plan is to assist the Company in attracting and retaining key
employees.  A total of  1,859,000 shares of  Common Stock has  been reserved for
issuance under the Plan. As of September 30, 1996, options to purchase 1,032,750
shares of Common Stock have been  granted thereunder. The options granted  under
the  Plan are incentive stock  options within the meaning  of Section 422 of the
Internal Revenue Code of 1986.
 
    The Plan  is administered  by the  Compensation Committee  of the  Board  of
Directors, which is comprised of directors who are not participants in the Plan.
Subject  to  the provisions  of  the Plan,  the  Compensation Committee  has the
authority to  administer  the  Plan  and  determine,  among  other  things,  the
interpretation  of any provision of the Plan,  the eligible employees who are to
be granted stock  options, the  number of  shares which  may be  issued and  the
option  exercise price. In no event will  options be granted at prices less than
the greater of (i) $3.20 per share (as adjusted) and (ii) the fair market  value
of the Common Stock on the date of grant. No option can be granted for a term of
more than ten years. The Company has not granted any outstanding options at less
than fair market value.
 
    In  addition, on December  1, 1993, in connection  with the Advance Clinical
acquisition, the Board of  Directors of the Company  adopted a second  incentive
stock  option plan, the terms and provisions  of which are identical to those of
the Plan. A total of 178,750 shares  of Common Stock were reserved for  issuance
under  this second incentive stock option plan, all of which have been issued to
employees of Advance Clinical.
 
    At the meeting of the Board of Directors of the Company held on February 15,
1996, the  Board of  Directors,  after review  of relevant  financial  analysis,
indication of interest for sale of the Common Stock and comparisons of similarly
situated  companies, determined that  the fair market value  of the Common Stock
was $11.00 per  share. Accordingly, the  Board of Directors  determined that  it
would  be in the best interest of the Company to cancel the 151,750 options that
had been granted to employees at a higher exercise price. The Board of Directors
canceled these options  and re-issued, effective  as of February  15, 1996,  the
same  number of  options to  each employee,  with a  strike price  of $11.00 per
share.
 
    In connection with  the Merger,  the Plan will  be amended  to increase  the
number  of shares reserved  for issuance thereunder and  the Advance Health Care
incentive stock option plan will  be merged with and  into the Plan. Holders  of
options  under the Advance Health Care  incentive stock option plan will receive
options   to   purchase   Common   Stock   under   the   Plan.   See    "Certain
Transactions--Merger of Advance Health Care With and Into the Company."
 
    Options are not transferable other than by will or under the laws of descent
and  distribution, and are exercisable during  the lifetime of the optionee only
by the optionee or his guardian or legal representative. Upon termination of the
optionee's employment with  the Company,  the period  of time  during which  the
stock  options  are exercisable  is  restricted to  three  months. The  Board of
Directors has the right to amend, suspend or terminate the Plan at any time, but
no such action after the Plan becomes effective can affect or impair the  rights
of  any  optionee  under  any  options granted  prior  to  such  action. Certain
amendments must be approved by the holders of Common Stock.

INCENTIVE COMPENSATION PLAN
 
    Employees of the  Company who  hold director-level positions  or higher  are
eligible  to receive annual incentive-based bonus  payments if the Company meets
or exceeds certain predetermined annual  performance goals. The bonuses  payable
under  the  incentive  compensation  plan  are based  on  a  percentage  of each
employee's salary. One-half of the bonus is payable upon the Company meeting the
predetermined  performance  goals,  with  the  other  one-half  subject  to  the
satisfaction  of certain performance goals as  determined by management for such
individual.
 
401(K) PLAN

                              CERTAIN TRANSACTIONS
 
WHITNEY DEBT FUND FINANCING
 
    On December 8, 1993,  the Company and  an affiliate of  J.H. Whitney &  Co.,
Whitney  Subordinated Debt Fund  L.P. (the "Whitney Debt  Fund"), entered into a
Note and Warrant Purchase Agreement pursuant to which the Whitney Debt Fund paid
the Company $7.0 million  in exchange for  the Whitney Note  and a warrant  (the
"Whitney  Warrant") to purchase  shares of Common Stock.  The Whitney Note bears
interest at the rate of 10.1% per annum, payable quarterly. Although the Whitney
Note has a seven-year term, the Company is obligated to prepay the indebtedness,
without penalty or premium, upon consummation of a public offering. See "Use  of
Proceeds."  The  Whitney  Warrant grants  the  Whitney  Debt Fund  the  right to
purchase an aggregate of 336,500 shares of Common Stock at an exercise price  of
$4.00  per share until December 8, 2003. The warrant contains certain demand and
piggy-back registration rights with respect to the underlying Common Stock.  See
"Share Eligible for Future Sale--Registration Rights."
 
TRANSACTION FEES RELATING TO THE ADVANCE CLINICAL ACQUISITION
 
    In  connection with the acquisition of Advance Clinical in 1993, the Company
agreed to pay a  fee of $250,000  each to two officers  of Advance Clinical  for
services relating to the acquisition. The total $500,000 fee is included as part
of  the Advance Clinical purchase  price. The Company paid  $100,000 of this fee
upon closing  of the  acquisition and  $200,000  in each  of February  1995  and
February 1996.
 
MANAGEMENT RELATIONSHIP WITH ADVANCE HEALTH CARE
 
    Prior  to the  consummation of  the Merger  of Advance  Health Care  and the
Company, as  described  below,  certain  management  employees  of  the  Company
provided  administrative and management services  to Advance Health Care. During
fiscal year 1994, the Company paid fees to Advance Health Care for such services
and the use of the office space. See Note 12 of Notes to Consolidated  Financial
Statements.  Each of Mr.  D. Halbert, the  Chairman of the  Board, President and
Chief Executive  Officer of  the Company,  and Mr.  J. Halbert,  Executive  Vice
President  and  Chief  Operating Officer  of  the  Company, served  in  the same
positions for Advance  Health Care.  Additionally, Mr.  Phillips, the  Company's
Senior  Vice President, Chief Financial  Officer, Secretary and Treasurer served
as Chief Financial Officer and Vice  President of Accounting for Advance  Health
Care.  Further, Messrs. D. Halbert, J. Halbert,  Faulkner and Ware served on the
Board of Directors of Advance Health Care.
 
    As of August 1, 1993,  the Company and Advance  Health Care entered into  an
agreement  for the provision  of mail pharmacy  and claims adjudication services
for the benefit  of employees of  certain subsidiaries of  Advance Health  Care.
During  fiscal year  1996, Advance  Health Care  paid the  Company approximately
$56,000 (the fair  market value  as determined by  the Board  of Directors)  for
these  services.  This  agreement  had  an  initial  one-year  term  and  renews
automatically for  12-month  periods  unless terminated  by  either  party  upon
written  notice delivered  90 days  prior to  the expiration  of any  term. This
agreement will terminate as of the effective date of the Merger.
 
WARRANTS TO BCBS OF TEXAS
 
    On November 25, 1995, the Company granted to BCBS of Texas the right to earn
up to four  warrants, each representing  the right to  acquire 66,750 shares  of
Common  Stock, in consideration of BCBS of  Texas causing additional lives to be
enrolled in the Company's PBM programs  (the "BCBS of Texas Warrants"). BCBS  of
Texas'  right to earn the BCBS of Texas Warrants expires November 25, 2000. Each
BCBS of Texas Warrant will not be exercisable until the first annual anniversary
of its issuance. At such time, the BCBS of Texas Warrant will be exercisable  in
whole  during a  four-year term at  an exercise  price of $11.00  per share. See
"Description of Capital  Stock--Warrants to  Purchase Common Stock."  As of  the
date  of this Prospectus, none of the BCBS  of Texas Warrants has been earned or
issued.
 
MERGER OF ADVANCE HEALTH CARE WITH AND INTO THE COMPANY
 
    Immediately prior to the consummation  of the Offering, Advance Health  Care
will merge with and into the Company. Such Merger will be consummated as a means
of simplifying the corporate structure of the Company and is intended to qualify
as  a tax  free reorganization.  Advance Health  Care currently  holds 3,125,000
shares of Common Stock. In the Merger,  the Company will cancel the shares  held
by  Advance Health Care and issue shares of Common Stock directly to the Advance
Health Care stockholders based upon their fully-diluted
 
                                       36
<PAGE>
proportionate ownership interests in Advance Health Care (collectively  referred
to as the "AHC Stockholders"). Immediately prior to the Merger, the indebtedness
owed  by  Advance Health  Care to  certain  of its  stockholders will  be repaid
through the issuance of additional shares of common stock in Advance Health Care
as follows: Advance Health Care currently owes approximately $750,000 to Halbert
& Associates, Inc. (which will be repaid through the issuance of 1,947 shares of
Advance Health  Care  common stock);  approximately  $350,000 to  Dr.  David  S.
Halbert  (which will  be repaid  through the issuance  of 906  shares of Advance
Health Care common  stock); and  approximately $1,320,000 to  Dr. Worley,  which
includes  approximately $900,000 of Advance  Health Care indebtedness assumed by
Dr. Worley (which will be repaid through the issuance of 3,434 shares of Advance
Health Care common stock). Halbert &  Associates, Inc. and Dr. Worley are  among
the   Selling  Stockholders  in  this   Offering.  See  "Principal  and  Selling
Stockholders." Following the repayment of its indebtedness, Advance Health  Care
will  distribute  the  stock of  certain  subsidiaries of  Advance  Health Care,
operating in businesses unrelated to the Company, to the AHC Stockholders. After
the spin-off and the repayment of  indebtedness referred to above are  effected,
Advance  Health Care will have no operations  or known liabilities, or assets of
its own other than its investment in the Company. The spin-off and the repayment
of indebtedness  will  not  impact  the number  of  outstanding  shares  of  the
Company's  Common Stock. In connection with  the Merger, the Advance Health Care
incentive stock option plan will be merged with the Plan, and holders of options
under the Advance Health Care incentive  stock option plan will receive  options
to  purchase  Common  Stock  under  the Plan.  See  "Risk  Factors  -- Potential
Liability for Rescission of Private Sales and under Section 5 of the  Securities
Act."
 
ISSUANCE OF SERIES B PREFERRED STOCK
 
    On  June  25, 1996,  the  Company and  BCBS of  Texas  entered into  a stock
purchase agreement (the "Series B  Stock Purchase Agreement") pursuant to  which
BCBS  of Texas purchased an aggregate of  2,597 shares of the Series B Preferred
Stock at an effective purchase price  of $3,850 per share. Upon consummation  of
this  Offering (at the  initial public offering  price of $9.00  per share), the
number of shares of Series  B Preferred Stock will  be adjusted to 4,444  shares
(at  an effective purchase price of $2,250 per share). BCBS of Texas has certain
registration rights in connection with its shares.  As of the date of sale,  the
conversion  rate of the  Series B Preferred Stock  was one-to-one. Following the
stock split of the Common Stock in connection with this Offering, each share  of
Series B Preferred Stock will be convertible into 250 shares of Common Stock.
 
    The  Company believes that all of the transactions set forth above were made
on terms no less  favorable to the  Company than could  have been obtained  from
unaffiliated  third parties. All future transactions between the Company and its
officers, directors, principal stockholders and affiliates will be approved by a
majority of the Board of Directors, including a majority of the independent  and
disinterested  outside directors on the Board of Directors, and will be on terms
no less favorable to the Company than could be obtained from unaffiliated  third
parties.

Common Stock and (ii) 5,000,000 shares of Preferred Stock, 5,000 shares of which

the  consummation of the Merger, 7,403,750 shares  of Common Stock, no shares of

outstanding.  Assuming the  underwriters' over-allotment option  is exercised in
full, upon consummation of the Offering,  7,800,817 shares of Common Stock  will
be outstanding.
 
    The  following  summary  of  certain  provisions  of  the  Common  Stock and
Preferred Stock does not purport to be complete and is subject to, and qualified
in its entirety by, the  Restated Certificate of the  Company and the Bylaws  of
the Company that are included as exhibits to the registration statement of which
this Prospectus forms a part and by the provisions of applicable law.
 
COMMON STOCK
 
    After  giving effect to the  Merger as if it had  occurred on June 30, 1996,
there were  5,400,750 shares  of Common  Stock outstanding  which were  held  of
record  by 53  stockholders, as  adjusted to  reflect (i)  the 250-for-one stock
split, (ii)  the  conversion of  the  Series A  Preferred  Stock and  (iii)  the
consummation  of the  Merger all  of which  will occur  immediately prior  to or
concurrently with the closing of this Offering. Common Stock is not  redeemable,
does  not have  any conversion  rights and  is not  subject to  call. Holders of
shares of  Common Stock  have  no preemptive,  redemption, conversion  or  other
subscription  rights. Holders of shares of Common Stock are entitled to one vote
per share on  any matter submitted  to a  vote of stockholders  of the  Company.
Cumulative  voting is  prohibited in the  election of directors.  The holders of
Common Stock are  entitled to receive  dividends, if any,  as and when  declared
from  time to time by the Board of Directors of the Company out of funds legally
available therefor. See "Dividend Policy." Subject to the rights of the  holders
of  Preferred Stock, upon liquidation, dissolution  or winding up of the affairs
of the Company,  the holders  of Common Stock  will be  entitled to  participate
equally  and ratably,  in proportion to  the number  of shares held,  in the net
assets of the Company available for distribution to holders of Common Stock. The
shares of Common Stock currently outstanding are, and the shares of Common Stock
offered  hereby  when   issued  will   be,  validly  issued,   fully  paid   and
nonassessable.
 
PREFERRED STOCK
 
    Upon  consummation of  this Offering, all  shares of the  Series A Preferred
Stock will convert automatically  into shares of Common  Stock at a  250-for-one
conversion  rate. All of the  shares of the Series  A Preferred Stock issued and
outstanding are held  by the  Canaan Investors  and the  Whitney Investors.  The
holders  of the Series A  Preferred Stock are entitled to  one vote per share on
matters submitted  to  a vote  of  the  stockholders and,  except  as  otherwise
provided  by law,  vote together with  the holders  of Common Stock  as a single
class.
 
    Holders of the  Series A  Preferred Stock are  entitled to  receive, out  of
funds  legally  available  therefor,  cumulative  dividends,  calculated without
compounding, equal to $80 per share per annum. Such cumulative dividends  accrue
and  accumulate  from the  date  of issuance  and are  payable  if, as  and when
declared by the Board of Directors of  the Company. Further, the holders of  the
Series  A  Preferred Stock  are  entitled to  any  dividends that  the  Board of
Directors may declare to be payable on  shares of Common Stock as if the  shares
of  the Series A Preferred Stock had been converted into shares of Common Stock.
Upon the liquidation, dissolution or winding  up of the Company, the holders  of
the  Series A Preferred  Stock have the  right, prior to  any existing or future
classes of  capital  stock,  to  receive $1,000  plus  all  accrued  and  unpaid
dividends  for  each  outstanding  share  of Series  A  Preferred  Stock  and to
participate equally and ratably with the holders of the Common Stock in the  net
assets  of the Company  available for distribution to  stockholders. On or after
August 4,  1999, the  holders  of 60%  of the  outstanding  shares of  Series  A
Preferred  Stock may require the  Company to redeem any  or all of such holders'
shares at a price equal to the greater of (i) the original price paid per share,
plus accrued  and unpaid  dividends, and  (ii)  the fair  market value  of  such
shares.  The payment  of the  redemption price,  if any,  will be  made in three
equal, annual  installments. Upon  the  consummation of  this Offering  and  the
conversion  of all  outstanding shares of  Series A Preferred  Stock into Common
Stock, all  accrued  but  unpaid  dividends on  the  Series  A  Preferred  Stock
dividends will be forfeited.

    Holders  of the  Series B Preferred  Stock are  not entitled to  vote on any
matter. The holders of the Series B Preferred Stock are entitled to receive, out
of funds legally  available therefor, cumulative  dividends, calculated  without
compounding,  equal to  $45.00 per  share per  annum. Such  cumulative dividends
accrue and accumulate from the date of  issuance and are payable on March 31  of
each  year. Further, the holders of the Series B Preferred Stock are entitled to
any dividends that the Board of Directors may declare to be payable on shares of
Common Stock as if  the shares of  Series B Preferred  Stock had been  converted
into  shares of Common Stock. Upon the liquidation, dissolution or winding up of
the Company, the holders of the Series  B Preferred Stock have the right,  prior
to  any existing  or future  classes of  capital stock,  but after  the Series A
Preferred Stock, to receive $10.0 million plus all accrued and unpaid  dividends
of  Series B  Preferred Stock  and to participate  equally and  ratably with the
holders of the  Common Stock  in the  net assets  of the  Company available  for
distribution  to stockholders. On  or after June  25, 1998, the  Company, in its
sole discretion, may redeem any or all of such holders' shares at a price  equal
to  the original price  paid per share,  plus accrued and  unpaid dividends. The
Company has the right to convert the Series B Preferred Stock into Common  Stock
at any time after the fifth anniversary of issuance. The conversion rate for the
Series  B Preferred Stock  will be proportionately  adjusted for the 250-for-one
stock split. If the Company forces such a conversion, the holders of the  Series
B  Preferred  Stock  will  be  entitled  to  piggy-back  registration  rights in
connection with future registered offerings of shares of Common Stock.
 
WARRANTS TO PURCHASE COMMON STOCK
 
    Effective  December  8,  1993,  in  connection  with  the  Advance  Clinical
acquisition,  the Company issued to the Whitney  Debt Fund a warrant to purchase
336,500 shares  of  Common Stock,  exercisable  in whole  or  in part  during  a
ten-year  term,  at  an exercise  price  of  $4.00 per  share.  In  addition, in
connection with the  Advance Clinical acquisition,  effective December 8,  1993,
the  Company issued to BCBS  of Maryland a warrant  to purchase 56,250 shares of
Common Stock,  exercisable in  whole during  a four-year  term at  an  aggregate
exercise  price of $337,500. The warrants  contain certain demand and piggy-back
registration rights relating to  the Common Stock  underlying the warrants.  See
"Shares Eligible for Future Sale--Registration Rights."
 
    On November 25, 1995, the Company granted to BCBS of Texas the right to earn
up to four BCBS of Texas Warrants, each representing the right to acquire 66,750
shares  of Common  Stock, in consideration  of BCBS of  Texas causing additional
lives to be enrolled in the Company's PBM programs. BCBS of Texas' right to earn
up to four BCBS of Texas Warrants expires November 25, 2000. Each BCBS of  Texas
Warrant  will not be exercisable until the first anniversary of its issuance. At
such time, the  BCBS of  Texas Warrant  will be  exercisable in  whole during  a
four-year  term at a per share  exercise price of $11.00. As  of the date of the
Prospectus, none of the BCBS of Texas Warrants has been earned or issued.
 
    In addition, prior  to the end  of September 1996,  the Company  anticipates
entering  into an agreement with VHA Inc. pursuant to which, among other things,
the Company will grant to  VHA Inc. the right to  earn up to ten warrants,  each
representing the right to acquire 28,125 shares of Common Stock in consideration
of  VHA  Inc. causing  additional  lives to  be  enrolled in  the  Company's PBM
programs (the "VHA Warrants").  VHA Inc.'s right to  earn the VHA Warrants  will
expire  five years after the  date of issuance. Each  VHA Warrant earned will be
exercisable in whole  beginning on  the first  anniversary of  its issuance  and
ending  on the fifth anniversary of the  issuance at an estimated exercise price
equal to 90% of the initial public offering price per share in this Offering.
 
    The Company has agreed  pursuant to a  letter of intent  to issue a  warrant
representing  the right  to acquire 84,500  shares of Common  Stock to Principal
Health Care, Inc. ("PHC") upon execution  of a definitive agreement pursuant  to
which  the Company is the provider of PBM  services for PHC and its wholly owned
subsidiaries (the "PHC Warrant"). The PHC  Warrant will be exercisable in  whole
beginning  on the  first anniversary  of its  issuance and  ending on  the fifth
anniversary of its issuance  at an exercise  price equal to  90% of the  initial
public offering price per share in this Offering.
 
    The foregoing description of the warrants issued by the Company is qualified
in  its entirety by reference to such warrants which have been filed as exhibits
to the Registration Statement of which this Prospectus constitutes a part.

VOTING AGREEMENTS
 
    In connection with the Canaan and Whitney capital investment, Advance Health
Care,  the Canaan  Investors, the Whitney  Investors and Messrs.  D. Halbert, J.
Halbert and Phillips entered into a  Voting, Co-Sale and Right of First  Refusal
Agreement  dated as of  August 4, 1993  (the "Voting Agreement").  In the Voting
Agreement, the stockholders agreed  to vote all  of their shares  in favor of  a
nine  member  Board of  Directors consisting  of two  persons designated  by the
Whitney Investors,  two persons  designated  by the  Canaan Investors  and  five
additional persons, at least two of whom may not be employees or officers of the
Company,  designated  by  Advance  Health Care  and  the  Company.  Further, the
stockholders agreed to establish an Audit Committee consisting of three members,
at least one of whom  will be a director nominated  by the Canaan Investors  and
the  Whitney Investors, and a Compensation Committee consisting of four members,
at least two of whom will be directors nominated by the Canaan Investors and the
Whitney Investors. The parties to the Voting Agreement have agreed to  terminate
such  agreement effective upon  consummation of this  Offering (the "Termination
Agreement.")
 
    Holders of the  Series B Preferred  Stock are  not entitled to  vote on  any
matter.  Pursuant to the Series  B Stock Purchase Agreement,  the holders of the
Series B  Preferred  Stock  (or  the  holders  of  Common  Stock  obtained  upon
conversion  of the Series B Preferred Stock) agree to consent to and execute any
documents in  connection with  any  proposed merger  of  the Company  where  the
Company would not be the surviving entity, the sale of a majority of the capital
stock of the Company, or the sale of all or substantially all of its assets.
 
    The  foregoing descriptions  of the Voting  Agreement, Termination Agreement
and Series  B  Stock Purchase  Agreement  are  qualified in  their  entirety  by
reference  to the  Voting Agreement  and Termination  Agreement which  have been
filed as  exhibits  to  the  Registration Statement  of  which  this  Prospectus
constitutes a part.
 
CERTAIN PROVISIONS OF THE COMPANY'S RESTATED CERTIFICATE AND BYLAWS
 
    Pursuant  to the Restated Certificate, the members of the Board of Directors
are divided into three classes of directors serving staggered three-year  terms,
with  the number of directors  in each class to be  as nearly equal as possible.
The term of office  of the members in  the first class will  expire at the  next
annual  meeting  of the  stockholders,  the second  class  will expire  one year
thereafter, and the third  class will expire one  year thereafter. The Board  of
Directors  has no current plans to  formulate or effect additional measures that
could have an anti-takeover effect.
 
    Section 102(b)(7) of the  Delaware General Corporation  Law provides that  a
Delaware corporation may include in its certificate of incorporation a provision
eliminating  or limiting the personal liability  of directors to the corporation
or its stockholders  for monetary  damages for  breach of  their fiduciary  duty
including   acts   constituting   gross   negligence,   except   under   certain
circumstances, including  breach of  the  director's duty  of loyalty,  acts  or
omissions  not in  good faith or  involving intentional misconduct  or a knowing
violation of law  or any transaction  from which the  director derived  improper
personal benefit. The Company's Restated Certificate provides that the Company's
directors are not liable to the Company or its stockholders for monetary damages
for  breach of  their fiduciary duties,  subject to the  exceptions specified by
Delaware law.
 
    The Company's Restated Certificate and Bylaws also provide that the  Company
will  indemnify its  directors and officers  to the fullest  extent permitted by
Delaware law. The Company is generally  required to indemnify its directors  and
officers  for all judgments, fines, loss, liability, settlements, legal fees and
other  expenses  incurred  in  connection  with  pending  or  threatened   legal
proceedings  because of the director's or officer's position with the Company or
another entity that  the director or  officer serves at  the Company's  request,
subject  to  certain  conditions, and  to  advance  funds to  its  directors and
officers  to  enable  them  to  defend  against  such  proceedings.  To  receive
indemnification,  the director or officer must have been successful in the legal
proceeding or acted in  good faith and  in what he reasonably  believed to be  a
lawful manner and the Company's best interest.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon  completion of this Offering, the Company will have 7,403,750 shares of
Common Stock outstanding, assuming  no exercise of  options after September  30,
1996  and  after giving  effect to  (i)  the 250-for-one  stock split,  (ii) the
issuance of 2,500,000 shares  of Common Stock upon  automatic conversion of  all
shares of Series A Preferred Stock and (iii) the consummation of the Merger, all
of  which will occur  immediately prior to  or concurrently with  the closing of
this Offering. Of  these shares, the  2,647,114 shares of  Common Stock sold  in
this   Offering  will  be  freely   tradeable  without  restriction  or  further
registration under  the  Securities  Act  except for  any  shares  purchased  by
"affiliates"  of the Company as that term  is defined in the Securities Act. The
remaining 4,756,636 shares of Common  Stock outstanding upon completion of  this
Offering are restricted securities as that term is defined in Rule 144 under the
Securities  Act ("Rule 144"). All  of these shares will  be subject to "lock-up"
agreements which prohibit their sale for a period of 180 days following the date
of this Prospectus without the prior consent of Hambrecht & Quist LLC.
 
    Upon expiration of  the 180-day  lock-up period, an  aggregate of  3,085,750
shares of Common Stock will be eligible for sale without restriction pursuant to
Rule 144(k) (as described below), and 1,670,886 shares will be eligible for sale
subject  to the volume, manner of sale and other applicable restrictions of Rule
144. In addition,  of the  1,310,250 shares of  Common Stock  issuable upon  the
exercise  of outstanding options,  approximately 602,850 shares  of Common Stock
are immediately issuable  upon the exercise  of vested options  and will  become
eligible  for  sale, if  such  options are  exercised,  after the  date  of this
Prospectus. The  holders  of such  options  have entered  into  180-day  lock-up
agreements in connection with this Offering.
 
    In  general, under  Rule 144  as currently in  effect, a  person (or persons
whose shares are  required to  be aggregated) whose  restricted securities  have
been outstanding for at least two years, including a person who may be deemed an
"affiliate"  of  the  Company, may  only  sell  a number  of  shares  within any
three-month period which does not exceed the  greater of (i) one percent of  the
then  outstanding  shares of  the Company's  Common Stock  (approximately 74,038
shares after this  Offering) or (ii)  the average weekly  trading volume in  the
Company's  Common Stock  in the four  calendar weeks  immediately preceding such
sale. Sales under Rule 144  are also subject to  certain requirements as to  the
manner  of sale, notice and the availability of current public information about
the Company. A person  who is not an  affiliate of the issuer,  has not been  an
affiliate  within three months  prior to the  sale and has  owned the restricted
securities for at least three years is  entitled to sell such shares under  Rule
144(k) without regard to any of the limitations described above.
 
    Beginning  90 days after the date  of this Prospectus, certain shares issued
or issuable upon  the exercise  of options granted  by the  Company or  acquired
pursuant  to the Plan prior to the date of this Prospectus will also be eligible
for sale in the public market pursuant to Rule 701 under the Securities Act.  In
general,  Rule  701  permits  resales  of  shares  issued  pursuant  to  certain
compensatory benefit plans  and contracts  commencing 90 days  after the  issuer
becomes  subject to the reporting requirements  of the Exchange Act, in reliance
upon Rule 144,  but without compliance  with certain restrictions  of Rule  144,
including  the holding period  requirements. As of September  30, 1996 and after
giving effect  to  the Merger,  the  Company had  options  outstanding  covering
707,400  shares which become exercisable at various  times in the future as such
options vest.  Any shares  of Common  Stock issued  upon the  exercise of  these
options will be eligible for sale pursuant to Rule 701.
 
    Prior to this Offering, there has been no market for the Common Stock and no
prediction  can be made as to the effect, if any, that market sales of shares or
the availability of such shares  for sale will have on  the market price of  the
Common  Stock. Nevertheless, sales of substantial amounts of Common Stock in the
public market may adversely affect the market price and may impair the Company's
future ability to raise capital through the public sale of its Common Stock.
 
REGISTRATION RIGHTS
 
    Substantially all of  the current stockholders  of the Company,  as well  as
BCBS  of Maryland and the Whitney Debt Fund upon exercise of their warrants, and
BCBS of Texas, as the holder of Series  B Preferred Stock and the BCBS of  Texas
Warrants  (collectively, the "Rights  Holders"), are entitled  to include in any
registration of the Company's Common Stock in a public offering, whether for its
own account or  for the  account of  another security holder  up to  a total  of
approximately  6,899,000 shares of outstanding Common Stock, assuming conversion
of all outstanding Preferred  Stock into Common Stock  and the full exercise  of
the outstanding
 
                                       43
<PAGE>
warrants (the "Registrable Shares"). Subject to certain limitations, the holders
of  at  least 60%  of the  shares currently  held by  the Canaan  Investors, the
Whitney Investors and Advance Health Care and their assigns may require, at  any
time  commencing six months after the date of this Prospectus, on two occasions,
that the Company cause their shares  to be registered under the Securities  Act.
Such  a demand by the Canaan Investors and the Whitney Investors must include at
least 50% of the outstanding shares issued to them. The managing underwriter  of
any  offering  in  which Rights  Holders  participate  may limit  the  number of
Registrable Shares to be included in the registration; provided that the  Canaan
Investors and Whitney Investors will be entitled to register on a pro-rata basis
among  such holders two shares  for every one share  held by Advance Health Care
that is included in a registration. In addition, the holders of at least 60%  of
the  shares  held by  the Canaan  Investors, the  Whitney Investors  and Advance
Health Care and their  assigns may require the  Company, on three occasions,  to
cause  their shares to  be registered on  a Form S-3  registration statement (or
other form with similar requirements) under the Securities Act at any time  such
form  is available to the  Company, but in no event  more than seven years after
the date of  this Prospectus. In  connection with the  Merger, the  registration
rights  of Advance Health Care  will be assigned to  the stockholders of Advance
Health Care. All of  the Rights Holders entitled  to registration rights,  other
than  the Selling Stockholders, have waived  such rights in connection with this
Offering.

</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  the   Selling
Stockholders,  their counsel and the  Company's 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 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  $.34 per share. The Underwriters may  allow, and such dealers may reallow, a
concession not  in  excess of  $.10  per share  to  certain other  dealers.  The
Representatives   of  the  Underwriters  have  informed  the  Company  that  the
Underwriters do not intend to confirm sales to accounts over which they exercise
discretionary authority. After the  initial public offering  of the shares,  the
offering  price and other selling terms may be changed by the Representatives of
the Underwriters.
 
    The Company has granted to the Underwriters an option, exercisable not later
than 30  days after  the date  of this  Prospectus, to  purchase up  to  397,067
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
which  the number of shares of  Common Stock to be purchased  by it shown in the
above table 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.

<PAGE>
    The  Company  and  the Selling  Stockholders  have 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.
 
    Under certain agreements between the Representatives and the stockholders of
the  Company  (or  their  respective  predecessors-in-interest),  the   existing
stockholders  of the Company  and of Advance Health  Care, including the Selling
Stockholders and the Company's directors and executive officers, who will own in
the aggregate 4,756,636  shares of  Common Stock  after the  Offering, may  not,
without  the  prior  written  consent  of Hambrecht  &  Quist  LLC,  directly or
indirectly, sell,  offer,  contract  to  sell, transfer  the  economic  risk  of
ownership  in, make any short sale, pledge or otherwise dispose of any shares of
Common Stock or any securities  convertible into or exchangeable or  exercisable
for  or any other rights to purchase  or acquire Common Stock beneficially owned
by them  during  the  180  day  period  following  the  effective  date  of  the
Registration  Statement. In addition,  the Company has  agreed that, without the
prior written consent of  Hambrecht & Quist LLC  on behalf of the  Underwriters,
the  Company will  not, directly or  indirectly, sell, offer,  contract to sell,
make any short sale, pledge, sell  any option or contract to purchase,  purchase
any  option or contract to sell, grant  any option, right or warrant to purchase
or otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exchangeable or exercisable for or any rights to purchase or
acquire Common Stock, or enter into any swap or other agreement that  transfers,
in  whole or in  part, any of  the economic consequences  or ownership of Common
Stock,  during  the  180  day  period  following  the  effective  date  of   the
Registration  Statement, except that the Company may issue, and grant options to
purchase, shares of Common  Stock under its current  stock option plans and  may
issue   shares  of   Common  Stock   in  connection   with  certain  acquisition
transactions, provided such shares are subject to the 180-day lock-up agreement.
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  was  determined by
negotiation among the Company, the Selling Stockholders and the Representatives.
Among the factors considered  in determining the  initial public offering  price
were  prevailing market  and economic 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.
 
                                 LEGAL MATTERS
 
    The  validity of the Common  Stock being offered hereby  will be passed upon
for the Company  by Akin, Gump,  Strauss, Hauer  & Feld, L.L.P.   Certain  legal
matters   in  connection  with  this  Offering  will  be  passed  upon  for  the
Underwriters by Brobeck, Phleger & Harrison LLP, Austin, Texas.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Advance ParadigM, Inc.:
 
    We  have  audited the  accompanying consolidated  balance sheets  of Advance
ParadigM, Inc.  (a  Delaware  corporation formerly  known  as  Advance  Pharmacy
Services,  Inc.) and subsidiaries as of March 31, 1995 and 1996, and the related
consolidated statements of operations, stockholders' equity (deficit), and  cash
flows  for each  of the three  years in the  period ended March  31, 1996. These
financial statements are  the responsibility  of the  Company's management.  Our
responsibility  is to express an opinion  on these financial statements based on
our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial  statements referred to above present  fairly,
in  all material respects, the financial  position of Advance ParadigM, Inc. and
subsidiaries as of March 31, 1995 and 1996, and the results of their  operations
and  their cash flows for each of the  three years in the period ended March 31,
1996, in conformity with generally accepted accounting principles.
 
    As explained in Note  2 to the financial  statements, the Company has  given
retroactive effect to the change in accounting for network claim costs.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  GENERAL:
    Advance  ParadigM, Inc. (API), a Delaware corporation formerly named Advance
Pharmacy Services, Inc.,  was formed  as a  wholly owned  subsidiary of  Advance
Health  Care, Inc. (AHC)  in July 1993.  The accompanying consolidated financial
statements include the accounts of API and its three wholly owned  subsidiaries,
Advance  ParadigM  Mail Services,  Inc.  (Advance Mail),  Advance  ParadigM Data
Services, Inc.  (Advance Data),  and Advance  ParadigM Clinical  Services,  Inc.
(Advance Clinical), which are collectively referred to as the Company.
 
    API  was formed when  AHC contributed its  wholly owned subsidiaries Advance
Mail and  Advance Data  subject to  a $500,000  note payable  (see Note  12)  in
exchange  for all  of the  then outstanding  shares of  API's Common  Stock. The
transaction was  accounted for  as  a reorganization  of entities  under  common
control in a manner similar to a pooling of interests. Accordingly, the accounts
of Advance Mail and Advance Data are based on historical cost, and operations of
Advance  Mail and Advance Data are included  from the date of their formation by
AHC. In December  1993, API  acquired all of  the outstanding  stock of  Advance
Clinical in a business combination accounted for as a purchase (see Note 8). The
operating  results for  Advance Clinical are  included for the  period since its
acquisition by API.
 
    The Company offers  an integrated  program of  pharmacy benefit  management.
Clinical,  rebate, and formulary services are provided through Advance Clinical.
Claims processing for prescription drugs  purchased at the Company's network  of
retail   pharmacies  is  provided  through   Advance  Data.  The  dispensing  of
prescription drugs through the mail is provided through Advance Mail.
 
    In the year ended March 31, 1996, the Company began marketing health benefit
management services  (HBM  Services)  to certain  health  plans,  pharmaceutical
manufacturers,  and  other research  and managed  care organizations,  and began
programs for disease management services with selected customers.
 
    The Company is currently in the  process of an initial public offering  (the
Offering)  of its $.01 par value Common Stock.  The Company plans to use the net
proceeds  from  the  Offering  (i)  to  retire  the  note  payable  to   Whitney
Subordinated  Debt Fund,  L.P., an affiliate  of a principal  stockholder of the
Company, in the amount  of $7.0 million, (ii)  to provide further automation  of
the  Company's Richardson,  Texas facility,  including capital  improvements and
equipment (which are estimated to be  approximately $2.9 million), and (iii)  to
expand  the  Company's  claims  processing system  (which  are  estimated  to be
approximately $1.8 million). The balance of the net proceeds, approximately $4.5
million, will be used to fund possible acquisitions of similar or  complementary
businesses and general corporate purposes.
 
    In connection with the Offering, the Company's redeemable Series A Preferred
Stock will automatically be converted into 2,500,000 shares of Common Stock. The
pro  forma information below gives  effect to such conversion  and the merger of
AHC with and into API (see Note 15).

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
CONSOLIDATION
 
    The accompanying financial statements  include the accounts  of API and  its
wholly   owned   subsidiaries.   All  significant   intercompany   accounts  and
transactions have been eliminated in consolidation.
 
USE OF ESTIMATES
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that  affect the  reported  amounts of  assets and  liabilities  and
disclosure  of contingent  assets and liabilities  at the date  of the financial
statements and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.
 
UNAUDITED INTERIM FINANCIAL STATEMENTS
 
    The  accompanying unaudited interim financial  statements have been prepared
by the Company in accordance  with generally accepted accounting principles  for
interim  financial information and  substantially in the  form prescribed by the
Securities and Exchange Commission in instructions  to Form 10-Q and Article  10
of  Regulation S-X. Accordingly, they do not  include all of the information and
footnotes required  by generally  accepted  accounting principles  for  complete
financial  statements. In the opinion of  the Company's management, the June 30,
1995 and 1996  unaudited interim financial  statements include all  adjustments,
consisting of normal recurring adjustments, necessary for a fair presentation of
results  for this interim period. The results of operations for the three months
ended June 30, 1995 and 1996 are not necessarily indicative of the results to be
expected for the full year or for any future period.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash  equivalents include  overnight investments  and money  market
accounts.
 
INVENTORIES
 
    Inventories consist of pharmaceuticals stated at the lower of cost or market
under the first-in, first-out method.
 
PROPERTY AND EQUIPMENT
 
    Property  and equipment are stated at cost less accumulated depreciation and
amortization.  Depreciation  is  computed  on  the  straight-line  method   over
estimated  useful  lives  ranging  from  three  to  ten  years.  Amortization of
leasehold improvements is  computed over the  lives of the  assets or the  lease
terms,  whichever is  shorter. Major renewals  and betterments are  added to the
property and  equipment accounts  while  costs of  repairs and  maintenance  are
charged  to  operating  expenses in  the  period  incurred. The  cost  of assets
retired,  sold  or  otherwise  disposed   of  and  the  applicable   accumulated
depreciation  are removed from the accounts, and  the resultant gain or loss, if
any, is reflected in the statement of operations.
 
INTANGIBLE ASSETS
 
    Intangible assets  represent the  excess  of cost  over  the fair  value  of
tangible  net assets acquired  (goodwill) in connection  with the acquisition of
Advance Clinical (see Note  8). Goodwill is amortized  on a straight-line  basis
over   40  years.   The  Company   continually  evaluates   whether  events  and
circumstances have occurred that indicate the remaining balance of goodwill  may
not  be recoverable or the useful life may be impaired. Amortization expense was
$115,000, $346,000, and $347,000 in 1994, 1995, and 1996, respectively.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
    The Company evaluates  whether events and  circumstances have occurred  that
indicate  the remaining estimated  useful life of  long-lived assets may warrant
revision or that the remaining balance of  an asset may not be recoverable.  The
measurement  of  possible impairment  is  based on  the  ability to  recover the
balance of assets from expected future  operating cash flows on an  undiscounted
basis.  In the opinion of management, no such impairment existed as of March 31,
1995 or 1996.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying values of cash, receivables, payables, and accrued  liabilities
approximate  the fair  values of these  instruments because  of their short-term
maturities. The  carrying value  of the  Company's debt  also approximates  fair
value as interest rates on the Company's existing debt approximates market.
 
REVENUE RECOGNITION
 
    Revenues  from  the dispensing  of pharmaceuticals  from the  Company's mail
service pharmacy are recognized when each prescription is shipped. Revenue  from
sales  of prescription drugs  by pharmacies in  the Company's nationwide network
and  claims  processing  service  fees  are  recognized  when  the  claims   are
adjudicated.   Clinical,  formulary,  rebate,  and  disease  management  service
revenues are recognized  as the  services are  performed and  rebates earned  in
accordance with contractual agreements.
 
FEDERAL INCOME TAXES
 
    Prior  to the formation of  API in July 1993,  Advance Mail and Advance Data
were included in the consolidated tax  return of AHC. For activities  subsequent
to  the formation of API, the Company  has filed consolidated federal income tax
returns separate from  AHC. The Company  has calculated its  tax provision on  a
stand-alone basis for all reported periods.
 
PRO FORMA NET INCOME PER SHARE
 
    Pro  forma net income  per share gives  effect to (i)  the conversion of the
redeemable Series  A Preferred  Stock  to Common  Stock,  (ii) the  issuance  of
836,320  shares of Common Stock  in the Offering, the  net proceeds of which are
intended to  be  used  to  retire  the $7.0  million  note  payable  to  Whitney
Subordinated  Debt  Fund, L.P.,  (iii) a  reduction of  interest expense  by the
amount of interest  on the  $7.0 million  note payable  and (iv)  the impact  to
shares  and options outstanding of the merger of AHC with and into API (see Note
15). Pro  forma net  income per  share is  computed using  the weighted  average
number of common and common equivalents shares outstanding during the year which
include  stock options  and warrants. As  required by the  Commission rules, all
warrants, options, and shares issued  during the year immediately preceding  the
initial   public  offering  are  assumed  to  be  outstanding  for  purposes  of
calculating pro forma net  income per share. The  primary and fully diluted  per
share amounts were the same as the effect of potentially dilutive securities was
antidilutive.
 
RECLASSIFICATION
 
    Certain  prior year amounts  have been reclassified  to conform with current
year presentation.
 
RESTATEMENT OF NETWORK CLAIM COSTS
 
    The Company has restated its financial statements for the three months ended
June 30, 1996,  and for all  prior periods  presented. When the  Company has  an
independent  obligation to pay  its network pharmacy  providers, the Company now
includes payments from plan sponsors for these benefits as revenues and payments
to its  pharmacy  providers  as  cost  of  revenues.  If  the  Company  is  only
administering  plan  sponsors'  network  pharmacy  contracts,  the  Company will
continue to record as net revenues the claims processing service fees. In  prior
periods,  the Company recorded  as net revenues only  the fees for administering
claims from network pharmacy providers.  The restatement increased revenues  and
cost of revenues as follows:

management  employees of  Advance Clinical.  These employment  agreements, which
expire in  December  1996,  provide  for certain  minimum  payments  should  the

regulations. The regulatory requirements with  which the Company must comply  in
conducting  its  business  vary from  state  to state.  Management  believes the
Company is in  substantial compliance with,  or is in  the process of  complying
with,  all  existing  laws and  regulations  material  to the  operation  of its
business. In management's opinion,  any existing noncompliance  will not have  a
material  adverse effect on the results  of operations or financial condition of
the Company.

    In December  1993, the  Company acquired  the outstanding  stock of  Advance

beginning of fiscal year 1994, condensed unaudited pro forma combined results of
operations for the year ended March 31, 1994, are as follows:

9.  CONCENTRATION OF BUSINESS:
    One customer  accounted  for  approximately  18.3%  of  the  Company's  1996
revenues.  One customer accounted for approximately  26.5% of the Company's 1995
revenues. No other customer accounted for over 10% of the Company's 1996 or 1995
revenues. Two customers accounted for approximately 54.8% of the Company's  1994
revenues.  On a pro  forma basis, assuming the  Advance Clinical acquisition had
occurred on  April  1,  1993,  these two  customers  would  have  accounted  for
approximately 49.5% of the Company's 1994 revenues.
 
10. REDEEMABLE PREFERRED STOCK AND COMMON STOCK:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
10. REDEEMABLE PREFERRED STOCK AND COMMON STOCK: (CONTINUED)
    CUMULATIVE DIVIDENDS--Holders of the redeemable Series A Preferred Stock are
    entitled to cumulative  dividends calculated  at an  annual rate  of 8%  per
    share  of the  original issuance  price of  $1,000, or  $80 per  share. Such
    cumulative dividends  accrue and  accumulate day  to day  from the  date  of
    original  issuance whether or not earned or  declared. As of March 31, 1996,
    the cumulative  undeclared  and unpaid  dividends  were $1,959,000  and  are
    included  in redeemable Series A Preferred Stock in the accompanying balance
    sheet. Upon conversion of the redeemable Series A Preferred Stock to  Common
    Stock, all such accrued and unpaid cumulative dividends shall be forfeited.
 
    RIGHT  OF  FIRST  OFFER--The Company  must  first  offer to  the  holders of
    preferred shares, and any holder of more than 3% of the capital stock of the
    Company, any future offering  of equity securities, convertible  securities,
    or debt-equity security combinations. This right does not apply to any stock
    dividends,  conversion share issuances, stock grants of up to 569,500 shares
    pursuant to the stock option plan, or  stock grants of up to 415,500  shares
    in connection with the acquisition of another entity.
 
    CONVERSION RIGHTS--The redeemable Series A Preferred Stock is convertible at
    any  time at  the option  of the  holder into  fully paid  and nonassessable
    shares of Common  Stock at  a conversion rate  equal to  the issuance  price
    divided by the Applicable Conversion Value, as defined, giving effect to any
    adjustments. At March 31, 1996, the conversion rate was 250-for-one.
 
    The  redeemable  Series  A  Preferred  Stock  is  automatically  convertible
    immediately prior to  the closing of  an underwritten public  offering on  a
    firm  commitment basis filed on  Form S-1 of the  Securities Act of 1933, as
    amended, covering the offer and sale of Common Stock for which proceeds (net
    of  underwriters'  discounts  and  commissions  but  before  calculation  of
    expenses)  equal or exceed $10,000,000 and at a price per share greater than
    twice the  original issuance  price  of the  redeemable Series  A  Preferred
    Stock, as adjusted for dilutive issuances of capital stock, stock dividends,
    stock splits, and reverse stock splits.
 
    PARTICIPATING  DIVIDENDS--The  redeemable  Series A  Preferred  Stock  has a
    participating feature whereby if dividends, other than stock dividends,  are
    declared  on  the  Common Stock,  the  holders  of the  redeemable  Series A
    Preferred Stock are entitled to receive an amount of dividends equal to that
    which would  be  payable on  the  number of  common  shares into  which  the
    redeemable Series A Preferred Stock is then convertible.
 
    REDEMPTION  RIGHTS--If on or after August  4, 1999, the Company has earnings
    after interest, but before  taxes, of at least  $1,500,000 for the  12-month
    period preceding the month of the request for redemption, the holders of 60%
    of  the then outstanding  shares of redeemable Series  A Preferred Stock may
    request the Company to  redeem such number of  shares of stock  outstanding.
    The  redemptions shall be made in three equal annual installments at a price
    which is  the greater  of (1)  the original  issue price  of the  redeemable
    Series  A  Preferred  Stock,  as  adjusted,  plus  all  accrued  and  unpaid
    dividends, or (2) the fair market value, as defined.
 
COMMON STOCK
 
    The Company is authorized to issue 7,500,000 shares of $.01 par value Common
Stock, of which  3,125,000 and 3,130,500  shares are issued  and outstanding  at

10. REDEEMABLE PREFERRED STOCK AND COMMON STOCK: (CONTINUED)
    During the  year  ended March  31,  1994,  the Company  issued  warrants  to
purchase  336,500 and 56,250 shares  of its Common Stock  at prices per share of
$4.00 and $6.00, respectively. During the year ended March 31, 1996, the Company
agreed to issue warrants  to purchase 267,000  shares of its  Common Stock at  a
price  of $11.00  per share  to a customer  contingent upon  future expansion of
member  lives.  As  of  March  31,  1996,  no  warrants  have  been  earned.  In
management's  opinion,  the  fair value  of  the  warrants at  the  date  of the
agreement was not material.
 
11. STOCK OPTION PLAN:
    During 1993, the  Board of  Directors and  the stockholders  of the  Company
adopted the 1993 Incentive Stock Option Plan and the Incentive Stock Option Plan
(the  "Plans"), which  provide for the  granting of qualified  stock options and
incentive options to officers and key employees of the Company. The options must
be granted with exercise prices  which equal or exceed  the market value of  the
common stock at the date of grant. As of March 31, 1996, the number of shares of
Common Stock issuable under the Plans may not exceed 858,000 shares. The Company
has  reserved 858,000 shares  of Common Stock  for such issuance.  The Plans are
administered by a compensation committee appointed by the Board of Directors  of
the Company.
 
    The  stock options generally vest  over 5-year periods. In  the event of the
sale or merger  with an outside  corporation gaining 50%  or greater  ownership,
options  granted  to  certain  employees become  100%  vested.  The  options are
exercisable for a period not  to exceed 10 years from  the date of grant. As  of
March  31, 1996,  276,750 options  were vested  at exercise  prices of  $3.20 to
$11.00 per share.
 
    The following is a summary of stock option activity:

    In October 1995, the Financial  Accounting Standards Board issued  Statement
No.  123,  "Accounting  for  Stock-Based  Compensation"  (SFAS  123).  SFAS  123
establishes  a   fair  value-based   method   of  accounting   for   stock-based
compensation.  The Company has decided to adopt SFAS 123 through disclosure with
respect to employee stock-based  compensation. Such disclosure requirements  are
effective beginning with the Company's 1997 fiscal year.
 
12. RELATED PARTY TRANSACTIONS:
    The  long-term debt  of the  Company is payable  to an  affiliate of certain
holders of Preferred Stock.  In connection with the  issuance of this debt,  the
Company paid a placement fee of $210,000 to a preferred stockholder.
 
    Prior  to 1995, the Company  occupied space in an  office facility leased by
AHC. In addition,  certain management employees  of AHC provided  administrative
and  management  services to  the Company.  In  connection with  the use  of the
facility and  the services  provided, AHC  charged the  Company $607,000  during
1994.  No such amounts were charged  in 1995 and 1996. In  July 1993, as part of
the formation of API, AHC transferred a debt obligation of $500,000 to API.  API
retired this obligation in August 1993.

12. RELATED PARTY TRANSACTIONS: (CONTINUED)
    In  connection with the acquisition of  Advance Clinical, the Company agreed
to pay a fee of $250,000 each  to two officers of Advance Clinical for  services
relating  to the acquisition. The  total fee of $500,000  is included as part of
the Advance Clinical purchase price. The Company paid $100,000 of this fee  upon
closing of the acquisition and $200,000 in February 1995 and February 1996.
 
    The  Company entered into an agreement with Advance Capital Markets (ACM) in
October 1993, pursuant to which ACM agreed to use its reasonable best efforts to
secure financing for the Company and to act as financial advisor and  investment
banker   for  the  acquisition  of  Advance  Clinical.  In  exchange  for  these
professional services,  the  Company  paid  ACM a  fee  of  $150,000,  which  is
equivalent  to or less than similar  fees incurred in arm's-length transactions.
The Chief Executive  Officer and  President of the  Company also  serves on  the
board of directors of ACM.
 
13. RETIREMENT PLAN AND POSTRETIREMENT BENEFITS:
    The  Company sponsors a retirement plan for all eligible employees. The plan
is qualified under  Section 401(k)  of the Internal  Revenue Code.  Compensation
expense associated with the Company's plan amounted to approximately $0 in 1994,
$50,000  in  1995, and  $102,000  in 1996.  Effective  in 1995,  the  Company is
required to  contribute  at  least  50%  of the  first  6%  of  salary  deferral
contributed by each participant.
 
14. INCOME TAXES:
    The  Company's  net  income  in  1996  was  offset  by  net  operating  loss
carryforwards. The Company had losses for tax purposes in 1994 and 1995 and  had
remaining  net  operating loss  carryforwards for  both financial  reporting and
federal income tax  purposes. The  Company had approximately  $1,918,000 in  net
operating  loss carryforwards for federal income tax purposes at March 31, 1996.
The net operating loss carryforwards will expire in the years 2002 through  2010
if not previously utilized.
 
    Deferred  income  taxes  reflect the  tax  consequences on  future  years of
temporary differences between the tax bases of assets and liabilities and  their
financial   reporting  bases   and  the   potential  benefits   of  certain  tax
carryforwards. The  significant  deferred tax  assets  and liabilities  and  the
changes in those assets and liabilities are as follows:

    Because  of the uncertainty of the realization of the net deferred tax asset
caused by historical operating losses, the Company recorded a valuation  reserve
equal  to its net deferred tax asset at March 31, 1995 and 1996. Management will
evaluate the appropriateness of the valuation  reserve in the future based  upon
historical  and anticipated operating  results of the  Company. The deferred tax
assets  arising  from   the  Advance  Clinical   acquisition,  if   subsequently
recognized,  will  be  allocated  to reduce  the  goodwill  attributable  to the
acquisition.

15. SUBSEQUENT EVENTS:
    On June 25,  1996, the  Company sold  an aggregate  of 2,597  shares at  its
Series  B Preferred  Stock to  a customer at  a price  of $3,850  per share. The
number of shares issued  is subject to potential  adjustment depending upon  the
price of the Offering.
 
    On  October 8, 1996, the  Company effected a 250-for-one  stock split of the
Company's Common Stock. Accordingly, all share  and per share amounts have  been
adjusted  to reflect the stock split as  though it had occurred at the beginning
of the initial period presented.
 
    Immediately prior to the consummation of  the Offering, AHC will merge  with
and  into the Company (the "Merger"). Such Merger will be consummated as a means
of simplifying the corporate structure of the Company and is intended to qualify
as a tax  free reorganization. AHC  currently holds 3,125,000  shares of  Common
Stock.  In connection with  the Merger, the Advance  Health Care incentive stock
option plan will be merged with  the Company's Incentive Stock Option Plan,  and
holders  of options  under the Advance  Health Care incentive  stock option plan
will receive  options to  purchase Common  Stock under  the Company's  Incentive
Stock Option Plan. In the Merger, the Company will cancel the shares held by AHC
and  issue shares of  Common Stock directly  to the AHC  stockholders based upon
their fully-diluted  proportionate  ownership  interests  in  AHC  (collectively
referred  to as  the "AHC Stockholders")  after giving consideration  to the new
shares of AHC to be  issued in repayment of debt  as indicated below. After  the
Merger,  there will be 2,903,750 shares  of Company common stock outstanding and
229,750 additional options outstanding at exercise prices of $0.67 to $2.71  per
share. Immediately prior to the Merger, AHC will distribute the stock of certain
subsidiaries  of AHC, operating  in businesses unrelated to  the Company, to the
AHC Stockholders. Prior to  such spin-off, certain indebtedness  owed by AHC  to
several  of its stockholders  (including some indebtedness of  AHC payable to an
affiliate of a preferred stockholder of the Company which will be assumed by  an
AHC  stockholder) will be  exchanged for additional shares  of AHC common stock.
The spin-off and exchange of indebtedness  will not impact the number of  shares
of  the Company's common  stock outstanding. After the  spin-off and exchange of
indebtedness referred to above  are effected, Advance Health  Care will have  no
operations, known liabilities, or assets of its own other than its investment in
the Company.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  ORGANIZATION:
    ParadigM  Pharmacy  Management,  Inc. (PPM),  a  Maryland  corporation (name
subsequently changed  to Advance  ParadigM  Clinical Services,  Inc.),  provides
pharmacy  management  services to  a variety  of healthcare  companies including
Health Maintenance  Organizations, Preferred  Provider Organizations  and  other
employee benefit plans.
 
    PPM  began operations on January 1, 1991.  During the period from January 1,
1991, through November 30, 1993, PPM was a wholly owned subsidiary of Blue Cross
and Blue Shield of Maryland, Inc. (Parent) and operated under common  management
with CFS Health Group, Inc. (CFS), another wholly owned subsidiary of Blue Cross
and Blue Shield of Maryland, Inc.
 
    Effective after the close of business on November 30, 1993, Advance Pharmacy
Services,  Inc.  (APS),  whose name  has  been subsequently  changed  to Advance
ParadigM, Inc.,  acquired all  of  the outstanding  capital  stock of  PPM.  The
accompanying  financial statements do not include  any accounting to reflect the
purchase transaction.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents include overnight investments and short-term notes
with maturities of 60 days or less.
 
REVENUE RECOGNITION
 
    Clinical, formulary,  and  rebate service  revenues  are recognized  as  the
services  are  performed  and  rebates  earned  in  accordance  with contractual
agreements. A  portion  of the  rebates  earned  is shared  with  the  Company's
customers  in accordance with contractual  agreements. Such amounts are included
in cost of revenues in the accompanying financial statements.
 
PROPERTY AND EQUIPMENT
 
    Property and  equipment are  stated at  cost. PPM  depreciates property  and
equipment on a straight-line basis over the following estimated useful lives:

Computer equipment and software............................  3 years
Furniture and fixtures.....................................  5 years
</TABLE>
 
DEFERRED REVENUE
 
    Deferred  revenue represents the unamortized portion of one-time payments to
PPM by pharmaceutical suppliers during 1992 as an incentive for PPM to obtain  a
specific  customer in a new line of business. This incentive was deferred and is
being amortized over the  24 months of the  initial customer's contract  through
June  30, 1994. The amortization of this  payment is included in revenues in the
accompanying statements of operations.
 
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    In connection with the acquisition of PPM by APS, PPM agreed to pay $195,000
of the legal and underwriting costs related to the transaction. These costs  are
included  in selling,  general and  administrative expenses  in the accompanying
statement of operations for the eleven months ended November 30, 1993.
 
3.  INCOME TAXES:
    The results of PPM's operations are included in the consolidated tax  return
of  the Parent for  federal income tax  purposes. PPM files  a separate Maryland
state income tax return and records its tax provision or benefit accordingly.
 
    A provision for  income taxes of  $750,000 has been  provided for  financial
reporting  purposes for the eleven months ended November 30, 1993. The provision
for income taxes includes deferred taxes resulting from temporary differences in
income for financial accounting and tax purposes, using the liability method.

                                                                    ---------
                                                                    ---------
</TABLE>
 
    PPM maintained a federal tax sharing  agreement with its Parent. Under  this
agreement,  the Parent allocated federal  tax expense of $39,000  to PPM for the
eleven months  ended November  30, 1993.  PPM's income  tax provision  has  been
recorded  as  if it  were  a stand-alone  company.  The differences  between the
federal tax allocations from its Parent  and the federal tax provision  recorded
in  the accompanying  statement of operations  have been  recorded as additional
capitalization from its  Parent in the  accompanying statement of  stockholder's
equity.
 
4.  CONCENTRATION OF BUSINESS:
    During  the  eleven  months ended  November  30,  1993, the  Parent  and CFS
collectively  constituted  32%  of   PPM's  revenues.  A  non-related   customer
constituted  approximately 18% of PPM's revenues  during the eleven months ended
November 30, 1993.
 
    During the  eleven  months  ended  November  30,  1993,  two  pharmaceutical
suppliers constituted approximately 27% of rebates.
 
    Between  November 30, 1993 and January  1, 1994, four customers constituting
approximately 38% of revenues for the eleven months ended November 30, 1993, did
not renew their contracts with PPM. Beginning January 1994, PPM contracted  with
three  new customers. These  new customers represented  approximately 37% of the
recorded revenues for the quarter ended March 31, 1994. One of the new customers
is APS, PPM's  new parent.  APS represented  approximately 17%  of the  recorded
revenues  for the  quarter ended  March 31,  1994. Management  believes that the
impact of  the  customer terminations,  when  coupled  with the  impact  of  new
customers,  will not have a material  adverse effect on PPM's financial position
or results of operations.
 
5.  RELATED-PARTY TRANSACTIONS:
    Through November  30, 1993,  PPM  had an  operating relationship  with  CFS,
whereby   CFS   paid  certain   administrative   costs  and   performed  certain
administrative services on behalf of PPM. PPM reimbursed CFS for the costs  paid
on PPM's behalf.
 
    PPM  provided clinical, administrative and various reporting services to its
Parent during  the eleven  months ended  November 30,  1993. Charges  for  these
services were approximately $307,000. This amount is included in revenues in the
accompanying statement of operations.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
5.  RELATED-PARTY TRANSACTIONS: (CONTINUED)
    PPM  leases administrative office facilities from  CFS. Rent expense for the
eleven months  ended November  30, 1993,  was approximately  $85,000. The  lease
expired  on June  30, 1994,  unless sooner terminated  pursuant to  terms of the
lease. Total  remaining payments  under this  lease at  November 30,  1993,  are
approximately $54,000.
 
    Through  November 30, 1993, PPM participated in its Parent's noncontributory
retirement plan  and  defined  contribution savings  and  retirement  plan.  The
allocated expense for both plans was not material to PPM.
 
6.  POSTRETIREMENT BENEFITS:
    Until  November  30,  1993,  PPM's employees  participated  in  its Parent's
postretirement  benefits.  Substantially  all   employees  subject  to   certain
requirements  became  eligible  for  those  benefits  when  they  reached normal
retirement age while working for PPM and had at least ten years of service.
 
    In December 1990, the Financial Accounting Standards Board issued  Statement
of  Financial Accounting Standards No. 106 (SFAS 106) "Employer's Accounting for
Postretirement Benefits Other  Than Pensions". This  standard requires that  the
expected cost of these benefits must be charged to expense during the years that
the  employees render  service. PPM adopted  the standard,  effective January 1,
1993, on a prospective basis, as permitted. The effect of this adoption was  not
material to the accompanying financial statements.
 
7.  COMMITMENTS AND CONTINGENCIES:
    Effective  with the sale of  PPM by Blue Cross  and Blue Shield of Maryland,
Inc. on  November  30, 1993,  PPM's  employees  no longer  participated  in  its
retirement, defined contribution and postretirement benefit plans. Management of
PPM  intends to implement new benefit plans which will also cover the employees'
unvested benefits under the former Blue Cross and Blue Shield of Maryland,  Inc.
plans.  Accordingly,  management has  provided a  reserve  on the  balance sheet
related to the assumption  of the unvested accumulated  benefits as of  November
30, 1993.
 
8.  SUBSEQUENT EVENT:
    Effective  December 1, 1993, the  Company entered into employment agreements
with two key executives, through November 1996, aggregating base compensation of
$690,000 over their term.  The contracts also  provide for additional  incentive
payments, subject to performance standards.
