PRODUCTS AND SERVICES

PHARMACY BENEFIT MANAGEMENT SERVICES

     The Company's  pharmacy benefit  management service involves the systematic
management  of  outpatient  prescription  drug  usage to  foster  high  quality,
cost-effective  pharmaceutical  care  through the  application  of managed  care
principles and advanced  information  technologies.  The Company offers core and
advanced PBM services to its customers in the U.S. and Canada. Core PBM services
consist of retail pharmacy  network  administration;  formulary  administration;
electronic  point-of-sale  claims  processing,  drug utilization review ("DUR");
mail pharmacy service; and benefit plan design  consultation.  Approximately 82%
of the members  served by the Company  have  access to  prescription  drugs both
through  one of the  Company's  retail  pharmacy  networks  and through its mail
pharmacy  facilities,  reflecting  the  Company's  emphasis on  providing  fully
integrated pharmacy services.  As part of its ongoing commitment to provide cost
containment  solutions  for its clients,  the Company  also offers  advanced PBM
services.  Advanced PBM services  include the development of advanced  formulary
compliance and therapeutic  substitution  programs;  therapy management services
such as prior  authorization,  therapy guidelines,  step therapy protocols,  and
disease  management  interventions;  and  sophisticated  management  information
reporting and analytic services.

     CORE PHARMACY BENEFIT MANAGEMENT SERVICES

     The Company contracts with retail pharmacies to provide  prescription drugs
to members of the pharmacy  benefit plans  managed by the Company.  In the U.S.,
these pharmacies  typically  discount the price at which they will provide drugs
to members in return for designation as a network pharmacy.  The Company manages
three  nation-wide  networks in the U.S. and one  nation-wide  network in Canada
that are  responsive  to client  preferences  related  to cost  containment  and
convenience  of access  for  members.  The  Company  also  manages  networks  of
pharmacies  that are under  direct  contract  with its managed  care  clients or
networks that ESI has designed to meet the specific  needs of some of its larger
clients.

     The Company uses on-line  electronic claims processing to provide effective
pharmacy benefit  management  services to its clients.  All retail pharmacies in
the Company's pharmacy networks communicate with the Company on-line and in real
time to process  prescription drug claims.  When a member of a plan presents his
or her identification  card at a network pharmacy,  the network pharmacist sends
the  specified  claim data in an industry  standard  format to the Company which
processes  the claim and responds to the pharmacy,  typically  within one or two
seconds. The electronic processing of the claim involves confirming the member's
eligibility  for  benefits  under the  applicable  health  benefit  plan and the
conditions to or  limitations  of coverage,  such as the amount of copayments or
deductibles  the member must pay;  performing  a  concurrent  DUR  analysis  and
alerting the pharmacist to possible drug  interactions  or other  indications of
inappropriate  prescription drug usage;  updating the member's prescription drug
claim record; and, if the claim is accepted,  confirming to the pharmacy that it
will receive payment for the drug dispensed.

     The Company  integrates its pharmacy network benefits with its mail service
pharmacy  benefits  provided  to its  clients.  It  operates  two  mail  service
pharmacies,  one located in  Missouri  and the other in  Arizona,  that  provide
members  with  convenient  access to  maintenance  medications,  and  enable the
Company and its clients to control drug costs through operating efficiencies and
economies of scale. In addition,  through its mail service pharmacy, the Company
is able to be directly involved with the prescriber and member, and is generally
able to achieve a higher level of generic and therapeutic substitutions than can
be achieved  through the retail  pharmacy  network,  which  further  reduces the
client's costs.

     Core PBM  services  also  involve  benefit  plan  design  and  consultation
services.  The Company offers  consultation and financial  modeling  services to
assist the customer in selecting a benefit plan design that meets the customer's
needs for member  satisfaction and cost control.  The most common benefit design
options offered by the Company are member  financial  incentives and limitations
on the drugs covered by the plan, including drug formularies;  copayments, which
may be a flat dollar amount or a percentage of the ingredient  cost of the drug;
deductibles or annual benefit  maximum;  generic drug  substitution  incentives;
incentives or  requirements  to use only network  pharmacies or to order certain
drugs only by mail; and  limitations on the number of days supply of a drug that
can be obtained.  The  selected  benefit  design is entered  into the  Company's
electronic  claims processing  system,  which enforces the plan design as claims
are  submitted  and enables the Company and its clients to monitor the financial
performance of the plan.

     During 1996, 67.0% of the Company's net revenues were derived from pharmacy
network and claims  administration  services.  During  1995 and 1994,  66.2% and
64.5%,  respectively,  of the  Company's net revenues were derived from pharmacy
network and claims  administration  services.  The number of claims processed by
the Company through its pharmacy  networks has increased from  approximately 3.9
million  claims in 1991 to  approximately  57.8 million  claims in 1996.  During
1996,  28.7% of the  Company's  net revenues  were  derived  from mail  pharmacy
services. During 1995 and 1994, 29.7% and 32.2%, respectively,  of the Company's
net  revenues  were  derived  from mail  pharmacy  services.  The number of mail
prescriptions  processed by the Company's  mail  pharmacy  service has increased
from approximately 0.6 million in 1991, to 2.8 million in 1996.

     ADVANCED PHARMACY BENEFIT MANAGEMENT SERVICES

     The Company provides advanced PBM services to its clients which involve the
application  of clinical  expertise  and  sophisticated  management  information
systems to manage the pharmacy benefit. An important PBM service provided by the
Company is the  enhancement of formulary  compliance.  Formularies  are lists of
drugs for which coverage is provided under the applicable  plan; they are widely
used in managed  healthcare  plans and,  increasingly,  by other healthcare risk
managers.  The Company  administers  a number of different  formularies  for its
clients that often identify  preferred drugs whose use is encouraged or required
through  various  benefit  design  features.  Historically,  many  clients  have
selected a plan design which  includes an open  formulary in which all drugs are
covered by the plan and preferred  drugs, if any, are merely  recommended.  More
advanced  formularies  consist  of  restricted  formularies,  in  which  various
financial or other disincentives exist to the selection of non-preferred  drugs,
or closed formularies,  in which benefits are available only for drugs listed on
the  formulary.  Formulary  preferences  can be  encouraged by  restricting  the
formulary through plan design features such as tiered copayments,  which require
the member to pay a higher amount for a nonpreferred  drug;  through  prescriber
education  programs,  in which the Company or the managed  care client  actively
seek to educate the prescribers about the formulary preferences; and through the
Company's  ExpressPreferenceSM  drug therapy management program,  which actively
promotes  therapeutic and generic interchanges to reduce drug costs. The Company
also  offers  ExpressTherapeuticsSM,  an  innovative  proprietary  DUR and  case
management  clinical   intervention  program,  to  assist  clients  in  managing
compliance  with the  prescribed  drug  therapy  and  inappropriate  prescribing
practices.

     ESI's  National  Pharmacy and  Therapeutics  Committee  (the  "Committee"),
composed of physicians and pharmacists,  evaluates drugs to determine whether it
is clinically appropriate to give formulary preference to one drug over another.
If clinical appropriateness is established to the Committee's satisfaction,  the
Committee  also  considers the  cost-effectiveness  of drugs in the same therapy
class. Once a client adopts a formulary,  the Company  administers the formulary
through the electronic claims processing system,  which alerts the pharmacist if
the prescriber  has not  prescribed the preferred  drug. The pharmacist can then
contact the prescriber to attempt to obtain the  prescriber's  consent to switch
the prescription to the preferred product.

     Through  the   development   of   increasingly   sophisticated   management
information and reporting  systems,  the Company manages the  prescription  drug
benefit more effectively. The Company has developed an on-line prescription drug
decision  support  tool  called  RxWorkbenchTM  that  enables the Company or the
client to analyze  prescription drug data to identify cost trends and budget for
expected drug costs,  to assess the financial  impact of plan design changes and
to  identify  costly  utilization  patterns.  These  systems  permit a medically
sophisticated  user,  such  as  a  clinical  pharmacist  employed  by  a  health
maintenance organization ("HMO"), to analyze prescription drug data on-line.

     The  Company's  electronic  claims  processing  system  also  enables it to
implement sophisticated intervention programs to assist in managing prescription
drug utilization.  The system can be used to alert the pharmacist to generic and
therapeutic  substitution  opportunities and formulary  compliance issues, or to
administer prior authorization and step-therapy  protocol programs at the time a
claim is submitted for processing.  The Company's claims  processing system also
creates a database  of drug  utilization  information  that can be accessed on a
retrospective basis to analyze  utilization trends and prescribing  patterns for
more intensive management of the drug benefit.

     The Company is  developing  disease  management  programs to assist  health
plans in managing the total healthcare  costs associated with certain  diseases,
such as diabetes  and asthma,  for which  pharmaceutical  therapy is a principal
treatment  regimen.  These  programs may entail  offering  telephone  counseling
services  and  mailing  information  about  the  disease  to  affected  members.
Additionally,   the  programs  may  include  periodic   reminders  to  encourage
compliance with the therapy. High risk or noncompliant members can be identified
and contacted for  individual  counseling,  and  physicians can be encouraged to
follow the health plan's  specified  therapy  protocol for treating the disease.
Programs  that  promote  compliance  with  the  drug  regimen  can  both  reduce
complications from the underlying disease and manage the severity of the disease
so that more expensive drugs or medical procedures can be avoided,  thus helping
to manage the total  healthcare  cost of the disease.  Additional  components of
these programs include member surveys,  treatment  guidelines for physicians and
educational newsletters.

PRACTICE PATTERNS SCIENCE, INC.

     The success of the Company's disease  management  programs will continue to
depend,  in part, on the development of sophisticated  information  systems that
can identify  members for  participation  in such  programs and then measure the
results of the  program.  PPS,  the  Company's  medical  information  management
subsidiary,  offers provider profiling, disease management support services, and
outcomes assessments, and has developed proprietary software to process and sort
medical claim,  prescription drug claim, and clinical laboratory data to produce
comprehensive  information  about  treatment  of  patients  that  can be used by
managed care  organizations and other companies  involved in disease  management
programs (including pharmaceutical  manufacturers and medical care providers) to
treat a particular  disease in a cost effective  manner. By linking together all
services provided to a particular member to treat a particular medical condition
and comparing such data to data in PPS's  normative  data bases,  PPS can assess
the effectiveness of treatment and calculate the total costs of that treatment.

     Clients  of PPS,  including  the  Company,  will  use the  information  PPS
develops to monitor the effectiveness of disease management programs and compute
and manage total healthcare costs, including prescription drug costs, for health
plan sponsors. The information can also be used to analyze the practice patterns
of healthcare providers and develop empirically-based "best practice" protocols,
which recommend a treatment regimen for specific diseases.

OTHER SERVICES

     In  addition  to  pharmacy  benefit  management  and  medical   information
management services, the Company also provides infusion therapy services, vision
care services and informed  decision  counseling  services.  Net revenues to the
Company  from  infusion  therapy and managed  vision care  services  represented
approximately $30.5 million in 1996, $21.7 million in 1995, and $12.9 million in
1994.

     OUTPATIENT INFUSION THERAPY SERVICES

     Infusion therapy services involve the  administration of prescription drugs
and other  products to a patient by  catheter,  feeding  tube or  intravenously.
IVTx's clients benefit from outpatient  infusion  therapy  services  because the
length of hospital stays can be reduced.  Rather than receiving infusion therapy
in a hospital,  IVTx can provide  infusion therapy services to patients at home,
in a physician's office or in a free-standing  center operated by a managed care
organization  or other  entity.  IVTx  provides  antimicrobial,  cardiovascular,
hematologic,  nutritional,  analgesic,  chemotherapeutic,  hydration, endocrine,
respiratory and AIDS management treatments to patients.  IVTx typically prepares
the  treatments  in one of its infusion  therapy  pharmacies,  which are usually
licensed  independently of the Company's mail services pharmacies,  depending on
the  applicable  state law. The  treatments  are either  administered  under the
supervision of IVTx's staff of registered  nurses or licensed  vocational nurses
who are  employed at one of the IVTx sites or, in areas where IVTx does not have
a facility, it contracts for services of registered nurses employed or otherwise
retained  by nursing  agencies,  who  administer  the  treatment.  IVTx may also
contract with physicians to provide medical director  services to its sites, and
contract for pharmacy  services for patients who live in outlying areas.  IVTx's
clients  consist  of managed  care  organizations,  third-party  administrators,
insurance  companies,   case  management  companies,   unions  and  self-insured
employers.

     The Company has facilities  supporting its infusion  therapy  operations in
Houston, Texas; Dallas, Texas; Columbia,  Maryland;  Maryland Heights, Missouri;
Northvale, New Jersey; Tempe, Arizona and West Chester, Pennsylvania. IVTx's DUR
system maintains patient profiles,  documents doses and supplies dispensed,  and
screens for drug  interactions,  incompatibilities  and  allergies  for patients
receiving infusion therapy services.

     VISION CARE SERVICES

     The  Company  offers a managed  vision  care  program  through a network of
approximately 5,500 vision care providers,  consisting primarily of optometrists
and a smaller number of  ophthalmologists.  Several  providers  offer service at
multiple locations, thereby allowing members to access the Company's vision care
product at approximately 7,500 locations in 49 states. The providers have agreed
to  provide,  at  specific  rates,  a routine  vision  examination  and  eyewear
(including  contact  lenses),  to members of the Company's  managed  vision care
plans. In addition to  administering  the network,  the Company grinds and edges
lenses and assembles  eyeglasses,  and  distributes  eyeglasses and contact lens
from  its  vision  lab  located  in Earth  City,  Missouri,  near the  Company's
headquarters.  The Company is  continuing  to develop,  pursuant to an agreement
with Ciba Vision Ophthalmics(R) U.S., ophthalmologic disease management programs
to be offered to plan sponsors.

     The Company  generally  sends its eyeglasses and contact lenses directly to
the local optometrist after  fabrication.  The quality of eyewear  fabricated at
the Company's optical lab meets or exceeds the standard for prescription eyewear
set by the Food and  Drug  Administration  according  to the  American  National
Standards  Institute's  policy for prescription  tolerance.  The Company manages
vision care benefits through its management  information  system which maintains
member  eligibility  information,  verifies  covered  benefits  and charges plan
participants  in accordance  with the provisions of the applicable  vision plan.
Additionally,  the system is used to bill clients and  provides  reports to help
clients manage the optical benefit.

     INFORMED DECISION COUNSELING

     The Company  anticipates  that it will begin offering  healthcare  decision
counseling  services through its Express Health LineSM service during the second
quarter  of 1997.  Specifically,  this  service  will  allow a member  to call a
toll-free telephone number and discuss a healthcare matter with a care counselor
who utilizes on-line decision support  protocols and other guidelines to provide
information  to the member to allow the member to make an  informed  decision in
seeking  appropriate  treatment.  Records  of each call will also be  maintained
on-line for future  reference.  The service  will be available 24 hours per day,
365 days  per  year.  Multilingual  capabilities  and  service  for the  hearing
impaired will also be available.  The counselors will provide  follow-up service
to members to determine if their  situation was resolved or if the counselor may
provide additional  assistance.  Member satisfaction and outcome assessment will
be tracked by the use of member  surveys,  a quality  assurance  plan and system
reports.

SUPPLIERS

     The Company  maintains an extensive  inventory  in its mail  pharmacies  of
brand and generic pharmaceuticals.  If a pharmaceutical is not in its inventory,
the Company can generally  obtain it from a supplier  within one to two business
days.  The  Company   purchases  its   pharmaceuticals   either   directly  from
manufacturers  or through  wholesalers.  During 1996,  approximately  79% of the
Company's  pharmaceutical  purchases were through one wholesaler,  most of which
were brand name pharmaceuticals. Generic pharmaceuticals are generally purchased
directly from  manufacturers.  The Company believes that alternative  sources of
supply for both generic and brand name pharmaceuticals are readily available.

CLIENTS

     The  Company  is a major  provider  of PBM  services  to the  managed  care
industry,  including  several large U.S.  HMOs.  Some of the  Company's  largest
managed care clients  include FHP, Inc.  ("FHP"),  NYLCare  Health  Plans,  Inc.
("NYLCare")  (formerly  Sanus Corp.  Health  Systems) and  Coventry  Corporation
("Coventry").  As of January 1, 1997, approximately 51% of the members receiving
ESI's PBM  services  are  members of HMOs.  The  Company  also  markets  its PBM
services through preferred  provider  organizations  ("PPOs"),  group purchasing
organizations ("GPOs"),  health insurers,  third-party  administrators of health
plans ("TPAs"), employers and union-sponsored benefit plans.

     The Company  has  entered  into  strategic  alliances  with a number of its
clients.  In October 1992 the Company  entered into a series of agreements  with
FHP,  which is an operator of HMOs  located  principally  in the western  United
States,  and its affiliated  HMOs. FHP received 200,000 shares of Class A Common
Stock in the  Company  as an  advance  discount  at the time it  entered  into a
contract making the Company the exclusive provider of PBM services to FHP for an
initial  term of five years.  FHP has the option to renew the  agreement  for an
additional five years. If FHP renews the agreement for a second  five-year term,
the Company will issue as an advance  discount a ten-year warrant to purchase an
additional 300,000 shares of Class A Common Stock,  exercisable at 90% of market
value at the time of renewal.  January,  1997 membership in FHP plans (including
affiliated  Take  Care  plans)  exceeds  2.0  million  members,  making  FHP the
Company's  largest customer in terms of membership,  but its contribution to the
Company's  net  revenues is less than 2% due to the fact that the  Company  only
records  the fees  related to  administering  FHP's  network  prescriptions  and
dispensing  mail pharmacy  prescriptions.  As previously  disclosed,  PacifiCare
Health Systems, Inc.  ("PacifiCare") publicly announced in August, 1996, that it
had reached an  agreement to acquire FHP. The  transaction  was  consummated  in
February,  1997,  and the Company is  continuing  to monitor  what effect such a
transaction may have on its future relationship with this client.

     In 1994  the  Company  entered  into a  strategic  alliance  with  Coventry
Corporation   ("Coventry"),   an  operator  of  HMOs  located  in  Pennsylvania,
Tennessee, Mississippi, and Missouri. Coventry received 25,000 shares of Class A
Common Stock at the time it entered into an exclusive  three-year  agreement for
PBM services that  commenced  January 1, 1995. If Coventry  renews the agreement
for a second  three-year  term, the Company will issue as an advance  discount a
ten-year warrant to purchase an additional  25,000 shares of the Company's Class
A Common Stock,  exercisable  at 90% of the market value at the time of renewal.
If the renewal period is for five years, the warrant will be for 58,000 shares.

     On December 31, 1995, the Company  entered into a series of agreements with
American  HealthCare  Systems  Purchasing  Partners,  L.P. (now known as Premier
Purchasing  Partners,  L.P.; the  "Partnership"),  a healthcare group purchasing
organization  affiliated with APS Healthcare,  Inc. (now known as Premier, Inc.;
"Premier").  Premier is the largest voluntary  healthcare  alliance in the U.S.,
formed as a result of the mergers in late 1995 of three  predecessor  alliances,
American HealthCare Systems, Premier Health Alliance and SunHealth Alliance. The
Premier alliance includes more than 240 integrated  healthcare  systems that own
or operate  approximately  750 hospitals and are  affiliated  with another 1,080
hospitals. Among other things, the agreements designate the Company as Premier's
exclusive  preferred  provider of  outpatient  PBM services to  shareholders  of
Premier and their  affiliated  healthcare  entities,  plans and facilities which
participate in the Partnership's  purchasing programs. The term of the agreement
is ten years,  subject to early  termination  by the  Partnership at five years,
upon payment of an early termination fee to the Company.  Premier is required to
promote the Company as the preferred  provider.  An individual Premier member or
affiliated managed care plan is not required to enter into an agreement with the
Company, but if it does so, the term of the agreement is for five years.

     As a result of the number of Premier plan members that receive PBM services
from the Company and the outcome of certain joint drug  purchasing  initiatives,
the Company issued 227,273 shares of its Class A Common Stock to the Partnership
in May, 1996.  The  Partnership  could also become  entitled to receive up to an
additional  2,250,000  million  shares,  depending  on the  number of members in
Premier-affiliated  managed  care  plans that  contract  for the  Company's  PBM
services. If the Partnership earns stock totaling over 5% of the Company's total
voting stock, it is entitled to have its designee  nominated for election to the
Board.  Under the terms of the agreements with the Partnership,  the Company now
provides service to a number of Premier affiliates.

     In January  1996,  the  Company  acquired  the  pharmacy  claim  processing
business of Eclipse  Claims  Services,  Inc.,  one of the largest  processors of
prescription  drug claims in Canada.  In connection with this  acquisition,  the
Company  entered into five-year  exclusive  contracts to provide PBM services in
Canada to both Prudential  Insurance  Company of America's  Canadian  Operations
("Prudential")  and  Aetna  Life  Insurance  Company  of  Canada  ("Aetna").  In
addition,  the Company also entered into a ten-year  strategic alliance with The
Manufacturers Life Insurance Company ("Manulife"), the largest provider of group
health  insurance  policies  in  Canada,  pursuant  to which the  Company is the
exclusive  provider of PBM services to Manulife.  As a result of this  alliance,
Manulife can earn up to  approximately  237,000  shares of Class A Common Stock,
depending on its  achievement  of certain  pharmacy  claim  volumes from 1996 to
2000.  If Manulife  does not terminate the agreement in either year 6 or year 10
of the  agreement on each such occasion it will receive a warrant to purchase up
to 118,000 shares of Class A Common Stock  exercisable at 85% of the then-market
value of such shares.  The actual number of shares entitled to be purchased will
depend upon claims volume in such years.

     The Company's pharmacy benefit management business continues to progress in
Canada,  with the Company  reaching  an  agreement  with  London Life  Insurance
Company  ("London  Life") whereby the Company will be the exclusive  provider of
PBM services to London Life, who  previously  acquired the assets of Prudential.
In  addition,  the Company  continues to provide PBM services in Canada to Crown
Life Insurance Company.

     The Company also provides  pharmacy benefit  management  services,  managed
vision care services and infusion  therapy  services to HMOs owned or managed by
NYLCare,  which is an indirect  subsidiary  of New York Life.  The Company  also
provides pharmacy benefit management services to insurance plans administered by
New York Life  pursuant to an  agreement  between the Company and New York Life.
New York Life has recently reorganized and transferred all of its group life and
health  insurance  business,  along  with this  agreement,  to  NYLCare.  Of the
Company's net revenues from pharmacy benefit management  services in 1996, 18.1%
was for  services  provided  to  members  of HMOs owned or managed by NYLCare or
insurance  policies  underwritten  or  administered  by New  York  Life.  Of the
Company's net revenues for managed  vision care and infusion  therapy  services,
58.5% was for services provided to members of HMOs owned or managed by NYLCare.

COMPANY OPERATIONS

     SALES AND  MARKETING;  CLIENT  SERVICE.  The Company  markets its  pharmacy
benefit  management  services in the United States  through an internal staff of
national marketing  representatives  and sales personnel and through independent
regional marketing  representatives  located in certain cities across the United
States.  These  marketing  representatives  are  supported  by a staff of client
service   representatives   located  in  the  Company's   Missouri  and  Arizona
facilities.  The  Company's  sales and marketing  personnel  and client  service
representatives  are organized by type of business  served  (i.e.,  managed care
group,  commercial  client  group,  etc.).  Marketing  in Canada is conducted by
marketing representatives located in Mississaugua,  Ontario, who are assisted by
Company  personnel  based  in the U.S.  Each of the  Company's  U.S.  facilities
contains a mail service  pharmacy,  client service,  member service and pharmacy
help  desk   capabilities,   and  full  electronic   pharmacy  claim  processing
capabilities, including pharmacy payment capabilities. At its Canadian facility,
the Company has client services and pharmacy help desk  capabilities.  IVTx, PPS
and ESVC also employ their own sales and marketing and client service  personnel
to take advantage of individual market opportunities.

     MEMBER SERVICES. The Company believes that client satisfaction is dependent
on member satisfaction. Members can call the Company toll-free, six days a week,
to obtain  information  about their  prescription drug plan. The Company employs
member service representatives who are trained to respond to member inquiries.

     PROVIDER  RELATIONS.  The Company's Provider Relations group is responsible
for contracting and administering  the Company's  networks of over 48,000 retail
pharmacies.  To participate in the Company's pharmacy networks,  pharmacists are
periodically  required to represent to the Company that their  applicable  state
licensing  requirements are being maintained and that they are in good standing.
Pharmacies  can contact the Company's  pharmacy help desks  toll-free,  24 hours
every day, for information and assistance in filling  prescriptions for members.
The Company's  Provider  Relations group also audits  pharmacies in the pharmacy
networks to determine compliance with the terms of the contract with the Company
or its clients.

     CLINICAL  SUPPORT.  The Company's Science  Department  employs a physician,
clinical  pharmacists and financial  analysts who provide  technical support for
the  Company's  advanced PBM services.  These staff members  assist in providing
high level  clinical  pharmacy  services  such as  formulary  development,  drug
information  programs,  clinical  interventions with physicians,  development of
drug therapy  guidelines and the evaluation of drugs for inclusion in clinically
sound therapeutic  switching programs.  The Science Department also analyzes and
prepares  reports on clinical  pharmacy  data for clients and conducts  specific
data analyses to evaluate the cost-effectiveness of certain drug therapies.

     MANAGEMENT   INFORMATION  SYSTEMS.  The  Company's  Management  Information
Systems department  supports the Company's pharmacy claims processing system and
other  management  information  systems  essential to the Company's  operations.
Because uninterrupted  point-of-sale  electronic pharmacy claims processing is a
significant  operational  requirement  for the  Company,  the claims  processing
systems located in the Company's Missouri and Arizona facilities are designed to
be redundant,  enabling the Company to do substantially all claims processing in
one facility if the other facility is unable to process claims.  The Company has
substantial capacity for growth in its claims processing facilities.

COMPETITION

     The Company  believes that the primary  competitive  factors in each of its
businesses are price, quality of service and breadth of available services.  The
Company  also  believes  that its  larger  PBM  competitors  offer  all core and
advanced pharmacy benefit  management  services,  and that most of the Company's
smaller competitors offer only core PBM services and some, but not all, advanced
PBM services.  The Company considers its principal competitive  advantages to be
independence from drug manufacturer ownership, strong managed care customer base
which  supports the  development  of advanced PBM  services,  and  commitment to
providing flexible and distinctive service to its customers.

     There are a large  number of  companies  offering  PBM services in the U.S.
Most of these companies are smaller than the Company and offer their services on
a local or regional basis. As a full service, national pharmacy benefit manager,
the Company  competes  with a number of larger,  national  companies,  including
Merck Medco Managed Care,  Inc. (a  subsidiary of Merck & Co.,  Inc.),  Caremark
International Inc. (a subsidiary of MedPartners,  Inc.), PCS, Inc. (a subsidiary
of Eli Lilly & Company),  Value Health,  Inc. (which announced in January,  1997
that  it  would  be  acquired  by  Columbia/HCA  Healthcare  Corporation),   and
Diversified  Pharmaceutical Services, Inc. (a subsidiary of SmithKline Beecham),
as well as numerous insurance and Blue Cross/Blue Shield plans, certain HMOs and
retail  drug  chains   which  have  their  own   pharmacy   benefit   management
capabilities. Many of these other companies have greater financial and marketing
resources than the Company.

     Consolidation  is  a  critical  factor  in  the   pharmaceutical   industry
generally.  Merger and  acquisition  activity in the  manufacturing  segment has
resulted in significant movements in market share. Competitors that are owned by
manufacturers  may have pricing  advantages  that are unavailable to the Company
and other independent PBMs.

     With  respect to its vision care  plans,  the  Company  competes  primarily
against  Vision  Service  Plan, a  California  not-for-profit  corporation,  and
certain other plans that provide  optical  services on a discounted  basis and a
large number of regional and local  providers.  With respect to infusion therapy
services, the Company competes with a number of large national companies as well
as with local providers.

GOVERNMENT REGULATION

     Various  aspects of the  Company's  businesses  are governed by federal and
state laws and  regulations.  Since  sanctions may be imposed for  violations of
these laws, 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 businesses.

     PHARMACY  BENEFIT  MANAGEMENT  REGULATION  GENERALLY.  Certain  federal and
related state laws and regulations affect or may 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  pharmacy  benefit
management  companies should be subject to FDA regulation.  At this hearing, FDA
officials  expressed  concern  about the  efforts of pharmacy  benefit  managers
(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.  Various  parties,  including the
Company,  have submitted written comments to the FDA regarding the basis for FDA
regulation of PBM activities.  It is the Company's  position that, while the FDA
may have jurisdiction to regulate PBMs that are owned by drug manufacturers, the
prescription drug benefit programs developed and implemented by independent PBMs
do not constitute the  distribution of materials that promote  particular  drugs
"on behalf of" any pharmaceutical  manufacturers,  and therefore, these programs
are not subject to FDA regulation.  The FDA has not published any proposed rules
to date on the  regulation of PBMs,  and there can be no assurance  that the FDA
will not seek to regulate  certain  aspects of the  Company's  pharmacy  benefit
management business.

     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  state healthcare 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 exception or safe harbor, a violation
of the statute may occur even if only one purpose 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 state consumer  protection laws discussed below, for
investigations  and  multi-state  settlements  relating to financial  incentives
provided by drug  manufacturers  to retail  pharmacies 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 or regulations,  or
that any such  challenge  would  not have a  material  adverse  effect  upon the
Company.

     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. The Company believes that the conduct of its
business is not subject to the fiduciary  obligations of ERISA, but 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.

     PROPOSED CHANGES IN CANADIAN  HEALTHCARE  SYSTEM. In Canada, the provincial
health plans  provide  universal  coverage for basic  healthcare  services,  but
prescription  drug coverage under the government  plans is provided only for the
elderly  and the  indigent.  A  proposal  has  recently  been  made by a Federal
government  healthcare  task force to include  coverage for  prescription  drugs
under the provincial  health insurance  plans,  which report was endorsed by the
Federal government's Health Minister.  This report is advisory in nature, and is
not binding upon the Federal or provincial governments. The Company is unable to
determine the likelihood of adoption of the proposal at this time.

     Numerous  state laws and  regulations  also affect aspects of the Company's
pharmacy benefit management business. Among these are the following:

     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 seventeen  states on October 25, 1995,  Merck Medco
Managed Care, Inc. ("Medco"), the PBM subsidiary of pharmaceutical  manufacturer
Merck & Co.,  agreed to have  pharmacists  affiliated  with Medco  mail  service
pharmacies  disclose to  physicians  and  patients the  financial  relationships
between  Merck,  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 now have some form of
legislation  affecting  the ability of the Company to limit access to a pharmacy
provider  network or from  removing  network  providers.  Such  legislation  may
require the Company or its client to admit any retail  pharmacy  willing to meet
the  plan's  price  and other  terms for  network  participation  ("any  willing
provider"  legislation);  or providing that a provider may not be removed from a
network   except  in  compliance   with  certain   procedures   ("due   process"
legislation).  The Company has not been  materially  affected by these  statutes
because it maintains a large network of over 48,000 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,  and many  states have  introduced  legislation  to  regulate  various
aspects of managed  care plans,  including  provisions  relating to the pharmacy
benefit.  For example,  some states  provide that members of the plan may not be
required to use network  providers,  but must instead be provided  with benefits
even  if  they  choose  to  use  non-network   providers  ("freedom  of  choice"
legislation).  Legislation  has  been  introduced  in some  states  to  prohibit
therapeutic  substitution,  or to require  coverage of all FDA  approved  drugs.
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 (HMOs and health 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 healthcare  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 often is 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.  Some states have adopted  legislation
providing that a pharmacy  participating in the state Medicaid program must give
the state the best price that the  pharmacy  makes  available to any third party
plan ("most favored nation" legislation).  Such legislation 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.  Such  legislation has been introduced but
not yet  enacted in Missouri  and  Arizona,  where the  Company's  mail  service
pharmacies  are located.  Such  legislation,  if enacted in either state,  could
adversely affect the Company's ability to negotiate discounts on its purchase of
prescription drugs to be dispensed by its mail service pharmacies.

     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.  In those cases in which the Company has contracts in
which it is  materially  at risk to provide the  pharmacy  benefit,  the Company
believes that it has complied with all applicable 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,  and in any event the Company  provides  services to
certain  customers,  such as union  health  and  welfare  funds  and  government
entities,  that are not subject to the  preemption  provisions  of ERISA.  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 principal mail service pharmacies
are located in  Missouri  and Arizona and the Company is licensed to do business
as a pharmacy  in each such  state.  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,  or be  licensed  by, 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,  although one state also requires that the Company
employ a pharmacist  licensed in that state. The Company has registered in every
state in which, to the Company's knowledge, such registration is required.

     One state has a statute that purports to prohibit  residents from obtaining
prescription  drugs by mail if the mail order business of the company dispensing
the drugs  represents  more than a specified  percentage of the company's  total
volume of pharmacy  business.  The  Company's  mail order  volume  exceeds  that
percentage.  The Company is licensed as a pharmacy in that state, no enforcement
action  has been  taken  under  the  statute  against  the  Company,  and to the
Company's knowledge,  no such enforcement action is contemplated.  Approximately
0.8% of the Company's  revenues come from mail  delivery of  prescription  drugs
into that state.  If an  enforcement  action  against the Company were commenced
under  that  statute,  the  Company  would  consider  all of  its  alternatives,
including challenging the validity of the statute.

     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.

     REGULATION  OF MANAGED  VISION  CARE.  The  Company's  managed  vision care
program is subject  to many of the same or  similar  state laws and  regulations
affecting the Company's pharmacy benefit management business. The Company offers
its vision care program on a  fee-for-service  and capitated  basis. The Company
has  determined  that it is required to obtain an HMO or  equivalent  license to
offer its vision care program on a capitated basis in several  states.  Until it
obtains  such  licenses,  the  Company  will  offer its vision  care  program to
customers based in such states only on a fee-for-service basis.

     REGULATION OF INFUSION  THERAPY  SERVICES.  The Company's  infusion therapy
services  business  is  subject  to many of the same or  similar  state laws and
regulations  affecting the Company's pharmacy management business.  In addition,
some states require that providers of infusion therapy services be licensed. The
Company  is  licensed  as a home  health  agency  and  pharmacy  in Texas,  as a
residential  service  agency and pharmacy in Maryland,  and as a pharmacy in New
Jersey,  Missouri,  Arizona and Pennsylvania.  The Company is also licensed as a
non-resident  pharmacy in various  states.  The Company  believes  that it is in
substantial compliance with such licensing requirements.

     The  Joint  Commission  on   Accreditation   of  Healthcare   Organizations
("JCAHO"), a non-profit, private organization, has established written standards
for healthcare  organizations  and home care services,  including  standards for
services  provided by home infusion therapy  companies.  The Company's  Maryland
Heights, Missouri, Dallas, Texas, Houston, Texas, Columbia,  Maryland, Northvale
New  Jersey  and West  Chester,  Pennsylvania  facilities  have  received  JCAHO
accreditation.  For the Tempe,  Arizona facility,  the Company elected the JCAHO
early survey option and received accreditation,  although this accreditation was
provisional  because the facility  did not have six months of operating  data at
the time of the initial  survey.  The Company  expects the final survey for this
facility to be conducted May, 1997.  When  accredited by JCAHO,  the Company can
market  infusion  therapy  services to Medicare  and Medicaid  programs.  If the
Company  expands  its home  infusion  therapy  services  to other  states  or to
Medicare  or  Medicaid  programs,  it may  be  required  to  comply  with  other
applicable laws and regulations.

     REGULATION  OF  INFORMED  DECISION   COUNSELING   SERVICE.   The  Company's
healthcare  decision support  counseling service is affected by many of the same
types of state  laws and  regulations  as the  Company's  other  activities.  In
addition,  all states  regulate  the  practice of medicine  and the  practice of
nursing.   The  Company  does  not  believe  its  informed  decision  counseling
activities  constitute  either the  practice  of  medicine  or the  practice  of
nursing.  However,  there can be no assurance that a regulatory agency in one or
more  states  may not assert a contrary  position,  and there is no  controlling
legal precedent for services of this kind.

     FUTURE  REGULATION.  The  Company  is unable  to  predict  accurately  what
additional Federal or state legislation or regulatory initiatives may be enacted
in the future  relating  to the  businesses  of the  Company  or the  healthcare
industry in general,  or what effect any such  legislation or regulations  might
have on the Company. There can be no assurance that federal or state governments
will not impose  additional  restrictions or adopt  interpretations  of existing
laws that  could have a  material  adverse  effect  the  Company's  business  or
financial position.

SERVICE MARKS AND TRADEMARKS

     The Company and its subsidiaries have registered the service marks "Express
Scripts", "PERx", "ExpressComp",  "ExpressReview",  "IVTx", "PERxCare" and "PTE"
with the United  States  Patent and Trademark  Office.  The Company's  rights to
these  marks  will  continue  so long as the  Company  complies  with the usage,
renewal filing and other legal  requirements  relating to the renewal of service
marks.  The Company is in the process of applying  for  registration  of several
other  trademarks  and  service  marks.  If the  Company is unable to obtain any
additional  registrations,  the  Company  believes  there  would be no  material
adverse effect on the Company.

INSURANCE

     The  dispensing of  pharmaceutical  products by the Company's  mail service
pharmacies, the fabrication and sale of eyewear by the Company, the products and
services  provided in connection with the Company's  infusion  therapy  programs
(including  the  associated  nursing  services),  and the  services  rendered in
connection  with  the  Company's   disease   management  and  informed  decision
counseling  service  may subject the Company to  litigation  and  liability  for
damages.  The Company believes that its insurance protection is adequate for its
present business operations, but there can be no assurance that the Company will
be able to maintain its professional and general liability insurance coverage in
the future or that such insurance coverage will be available on acceptable terms
or  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.

EMPLOYEES

     As of March 1, 1997, the Company and its  subsidiaries  employed a total of
1,477 employees in the U.S. and 36 employees in Canada.

ITEM 2 - PROPERTIES

     The Company operates its U.S. pharmacy benefit  management  business out of
leased facilities located in Maryland Heights,  Missouri, and Tempe, Arizona. In
addition,  the Missouri  facility houses the Company's  corporate  offices.  The
Canadian  PBM  business  operates  out of  leased  facilities  in  Mississaugua,
Ontario.  The  Company's  informed  decision  counseling  service  and  its  PPS
subsidiary  are also operated out of the Company's  Missouri site. The Company's
vision care business  operates out of leased  facilities  located in Earth City,
Missouri,  from which it distributes contact lenses, grinds and edges lenses and
assembles  eyeglasses.  The leased  facilities  supporting the infusion  therapy
operations are located in Maryland Heights,  Missouri,  Dallas,  Texas; Houston,
Texas;  Columbia,  Maryland;  Tempe,  Arizona;  Northvale,  New  Jersey and West
Chester,  Pennsylvania.  IVTx's  offices are located at the  Company's  Maryland
Heights, Missouri site.

     The Company  believes its facilities  have been generally well  maintained,
are in good  operating  condition  and are  adequate for the  Company's  current
requirements.

     The Company owns computer  systems for both the Missouri and Arizona sites.
The Company's software for DUR and other products has been developed  internally
by the Company or purchased under  perpetual,  nonexclusive  license  agreements
with third parties.  The Company's computer systems at each site are extensively
integrated   and  share  common  files   through  a  local  area   network.   An
uninterruptable   power  supply  and  diesel   generator  allows  the  Company's
computers,  telephone  systems  and mail  pharmacy  at each site to  continue to
function  during a power  outage.  To protect  against loss of data and extended
downtime,  the Company stores  software and redundant  files at both on-site and
off-site  facilities on a regular basis and has  contingency  operation plans in
place.

ITEM 3 - LEGAL PROCEEDINGS

     The Company is a party to legal and administrative  proceedings  arising in
the ordinary course of its business. The proceedings now pending are not, in the
Company's opinion, material either individually or in the aggregate.

     Over 100 separate  lawsuits  have been filed by retail  pharmacies  against
drug manufacturers and certain pharmacy benefit managers  challenging brand drug
pricing  practices  under various state and federal  antitrust  laws.  The suits
allege,  among other things,  that the manufacturers  have offered,  and certain
pharmacy benefit managers have knowingly accepted, discriminatory discounts that
violate the Robinson-Patman  Act. Certain  price-fixing claims under the Sherman
Act against the  manufacturer  defendants were settled,  with the  manufacturers
agreeing not to refuse to pay retrospective discounts to retail pharmacies based
on their status as such. The Company is not a party to any of these proceedings.
However,  if these  discounts  and rebates are  determined  to have violated the
Robinson-Patman  Act, then the availability to the Company of certain discounts,
rebates and fees that it presently receives could be adversely affected. No date
has been set for trial of these claims, and the Company can give no assurance as
to the ultimate outcome.

ITEM 4 - SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were  submitted to a vote of security  holders during the fourth
quarter of 1996.

     ITEM 7 - MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND
RESULTS OF OPERATIONS

OVERVIEW
     The  Company  principally  derives  its  revenues  from the sale of network
pharmacy services through its nationwide  networks of retail pharmacies and from
the  sale  of  pharmaceuticals  by its  mail  pharmacies  and  infusion  therapy
pharmacies  to  members  of health  benefit  plans  sponsored  by the  Company's
clients.   Net  revenue  of  the  Company   includes  the  ingredient   cost  of
pharmaceuticals dispensed by the mail pharmacies and pharmacies in the networks,
except where the  Company's  mail service  pharmacies  dispense  pharmaceuticals
supplied  by the  Company's  clients,  or where the Company  merely  administers
contracts for the client's  pharmacy  network.  In these  situations the Company
records only dispensing and administrative fees as net revenue.

     The Company's  vision care program derives its revenue from  administrative
fees and from the sale of eyeglasses and contact lenses to members.  The Company
also derives revenue from medical  information  management  services,  including
disease management support services and provider profiling services.

RESULTS OF OPERATIONS
     The following  table sets forth certain  financial  data of the Company for
the periods  presented as a percentage of net revenues and the percentage change
in the dollar  amounts of such financial data for 1996 compared to 1995 and 1995
compared to 1994.

YEAR ENDED DECEMBER 31, 1996, COMPARED TO 1995

     NET  REVENUES.  Net revenues  for 1996  increased  $229,155,000,  or 42.1%,
compared to 1995. Net revenues from the Company's claims processing services and
mail pharmacy  services  increased 41.8% in 1996,  compared to 1995. The primary
reason for this increase was a $157,609,000, or 43.7%, increase in revenues from
pharmacy  claims  processed  reflecting a 34.9% increase in the number of claims
processed,  and a 6.5% increase in average  revenue per claim  compared to 1995.
Revenue from the Company's  mail pharmacy  services  increased  $60,628,000,  or
37.5%, reflecting a 30.1% increase in the number of prescriptions dispensed, and
a 5.7% increase in the average revenue per prescription dispensed. The increases
in average revenue per claim and per prescription dispensed are primarily due to
increases in the ingredient costs of drugs for customers utilizing the Company's
pharmacy networks and mail pharmacy services,  partially offset by lower pricing
offered by the Company in response to continued competitive pressures.

     The  increase  in the  number of claims  processed  and the  number of mail
service  pharmacy  prescriptions  dispensed  reflects  a 22.2%  increase  in the
average number of members served from  approximately  8.1 million members served
at December 31, 1995 to approximately 9.9 million members served at December 31,
1996. The percentage  increase in claims processing revenues continues to exceed
the  percentage  increase  in mail  service  revenues,  as the price  difference
between  mail  pharmacy   prescriptions   and  network  pharmacy   prescriptions
decreases.  Management  believes this trend will continue in 1997.  Net revenues
from the  Company's  vision  and  infusion  therapy  services  increased  41.0%,
compared to 1995, as a result of the growth in the number of members who receive
these  services.   The  Company's  medical  information  management  subsidiary,
Practice  Patterns  Science,  Inc.  ("PPS"),  also  contributed to the Company's
success in 1996.

     COST OF REVENUES.  Cost of revenues  for 1996  increased  $206,599,000,  or
43.2%,  compared to 1995.  The  percentage  increase in cost of revenues was 1.1
percentage points more than the increase in revenues,  thus gross profit margins
decreased  slightly.  For both claims and mail pharmacy  services,  gross margin
decreased  slightly due to scheduled fee reductions under the Company's  amended
contract  with  NYLCare  Health  Plans,  Inc.  ("NYLCare")  and as a  result  of
competitive pressures.  These factors were offset by an increase as a percentage
of net revenues in the fees received from drug  manufacturers in connection with
the Company's drug purchasing and formulary management programs and economies of
scale in direct  processing  costs.  Management  expects the trend towards lower
margins to continue in 1997. The cost of revenue for vision and infusion therapy
services  increased 46.2%,  which is 5.2 percentage points above the increase in
revenues from these  services,  compared to 1995.  This was  principally  due to
costs related to the continued  expansion of vision and infusion therapy service
operations in order to serve a larger client base.

     SELLING,  GENERAL AND ADMINISTRATIVE.  Selling,  general and administrative
expenses  increased  $11,803,000,  or 31.6%,  for 1996,  compared  to 1995.  The
primary  reason for the increase  was the  additional  expenditures  incurred to
expand the Company's marketing capabilities, together with increases in expenses
for information systems, additional clinical programs and added costs for client
and  administrative  support  functions  to enhance  management  of the pharmacy
benefit.  The Company is continuing  its  commitment to expand its capability to
provide for future growth and enhance the level of service for its members.

     OTHER INCOME,  NET. Other income, net was $3,450,000 for 1996,  compared to
$757,000 for 1995,  primarily as a result of the investment of the proceeds from
the sale of 1,150,000  shares of Class A Common  Stock in April 1996,  increased
cash flow from  operations  and higher  interest rates on invested cash balances
compared to 1995.

     PROVISION  FOR INCOME  TAXES.  The  provision for income taxes for the year
ended  December 31, 1996, was  $16,932,000  compared to $11,307,000 in the prior
year. The effective tax rate was 39.3% in 1996 compared to 38.2% for 1995.

     NET  INCOME.  As a result of the  foregoing,  net income for the year ended
December 31, 1996, increased $7,821,000, or 42.7%, compared to 1995.

     EARNINGS  PER SHARE.  The Company  reported  earnings per share of $1.60 in
1996 compared to $1.20 in 1995, a 33.3% increase. The weighted average number of
shares used in the  calculations  was 16,350,000 in 1996 and 15,293,000 in 1995,
or an increase of 6.9%.  The increase was  primarily due to the April 1996 stock
offering of 1,150,000  shares and the April 1996  issuance of 227,273  shares in
connection with the contractual agreement with Premier, Inc.

YEAR ENDED DECEMBER 31, 1995, COMPARED TO 1994

     NET  REVENUES.  Net revenues  for 1995  increased  $159,956,000,  or 41.6%,
compared to 1994. Net revenues from the Company's claims processing services and
mail pharmacy  services  increased 40.5% in 1995,  compared to 1994. The primary
reason for this increase was a $112,758,000, or 45.5%, increase in revenues from
pharmacy  claims  processed  reflecting a 62.9% increase in the number of claims
processed, which was partially offset by a 10.7% decrease in average revenue per
claim  compared to 1994.  Revenue  from the  Company's  mail  pharmacy  services
increased  $37,879,000,  or 30.6%,  reflecting a 33.6% increase in the number of
prescriptions  dispensed,  offset  in part  by a 2.2%  decrease  in the  average
revenue per prescription dispensed.  The reductions in average revenue per claim
and per  prescription  dispensed  are the result of  competitive  pressures  and
continued higher utilization by HMO members at comparatively lower pricing, plus
the  impact of a price  reduction  as a result of  amendments  to the  Company's
agreements with NYLCare and its affiliates,  effective  January 1, 1995,  offset
somewhat by moderate increases in drug costs.

     The  increase  in the  number of claims  processed  and the  number of mail
service  pharmacy  prescriptions  dispensed  reflects  a 42.1%  increase  in the
average number of members served from  approximately  5.7 million members served
at December 31, 1994 to almost 8.1 million  members served at December 31, 1995.
The percentage  increase in claims  processing  revenue  continues to exceed the
percentage  increase in mail service revenues,  as the price difference  between
mail pharmacy  prescriptions and network pharmacy prescriptions  decreases.  Net
revenues  from the  Company's  vision and infusion  therapy  services  increased
68.1%,  compared to 1994, as a result of the growth in the number of members who
receive these services.

     COST OF REVENUES.  Cost of revenues  for 1995  increased  $140,132,000,  or
41.4%,  compared to 1994.  The  percentage  increase in cost of revenues was 0.2
percentage points less than the increase in revenues,  thus gross profit margins
increased  slightly.  For both claims and mail pharmacy  services,  gross margin
increased  slightly due to significant  economies of scale, which were partially
offset by  several  factors.  First,  the  amended  contract  with  NYLCare  and
comparatively  greater sales to HMOs reduced the average  revenue per claims and
per prescription, compared to 1994. Also, the Company experienced a reduction as
a percentage  of net revenues in the fees received  from drug  manufacturers  in
connection with the Company's drug purchasing and formulary management programs.
The cost of revenue for vision and infusion  therapy  services  increased 77.8%,
which is 9.7  percentage  points  above the  increase  in  revenues  from  these
services,  compared to 1994.  This was  principally  due to costs related to the
continued expansion of vision and infusion therapy service operations.

     SELLING,  GENERAL AND ADMINISTRATIVE.  Selling,  general and administrative
expenses increased $11,418,000, or 44.1%, for 1995 compared to 1994. The primary
reason for the increase was the additional  expenditures  incurred to expand the
Company's  marketing  capabilities,  together  with  increases  in expenses  for
information  systems and additional  clinical programs to enhance  management of
the pharmacy benefit.

     OTHER  INCOME,  NET.  Other  income,  net was $757,000 for 1995 compared to
$305,000 for 1994,  primarily as a result of higher  interest  rates on invested
cash balances in 1995.

     PROVISION  FOR INCOME  TAXES.  The  provision for income taxes for the year
ended  December 31, 1995 was  $11,307,000  compared to  $8,053,000  in the prior
year. The effective tax rate was 38.2% in 1995 compared to 38.8% for 1994.

     NET  INCOME.  As a result of the  foregoing,  net income for the year ended
December 31, 1995 increased $5,604,000, or 44.0%, compared to 1994.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's  continued growth has resulted in an increase in the level of
cash flow during each of the last three years of operations.  Cash flow from net
income before charges for depreciation and amortization (or operating cash flow)
totaled $32.9 million, $22.7 million, and $16.0 million in 1996, 1995, and 1994,
respectively. Operating cash flow fully funded net increases in non-cash working
capital  and  capital  expenditures  in  1996,  1995,  and  1994,  respectively.
Management  expects  to  continue  to fund a  substantial  portion of its future
anticipated  capital  expenditures  and net increase in non-cash working capital
with  operating  cash flow.  The Company also sold  1,150,000  shares of Class A
Common Stock in April 1996,  the net proceeds of which were  $52,592,000.  These
funds have been invested in short-term investments and are available for general
corporate  purposes and for strategic  acquisitions or affiliations as discussed
below.

     The Company  maintains a $25 million line of credit with Mercantile Bank of
St. Louis,  N.A. which expires on May 28, 1997. The Company also maintains a $25
million line of credit with The First National Bank of Chicago  expiring October
30, 1997. The terms and conditions of the lines of credit are similar in nature.
At December 31, 1996 and 1995, there were no borrowings outstanding on either of
these  lines of  credit.  However,  during a brief  period  during the first and
second quarters of 1995, the Company had borrowings outstanding of $3 million.

     As of March 1, 1997, the Company had  repurchased a total of 237,500 shares
of its Class A Common  Stock  under the  open-market  stock  repurchase  program
announced by the Company on October 25, 1996.  The Company's  Board of Directors
approved  the  repurchase  of up to 850,000  shares,  and placed no limit on the
duration of the program.  Purchases will be in such amounts and at such times as
the  Company  deems  appropriate  based  upon  prevailing  market  and  business
conditions.  Management  believes the Company's capital resources are sufficient
to fund this program.

     In January  1996,  the Company,  through ESI Canada,  Inc., a  wholly-owned
subsidiary,   purchased  certain  assets,   software  licenses  and  the  claims
processing business of Eclipse Claims Services, Inc. for $940,000. Eclipse was a
processor of Canadian pharmacy claims.

     The  Company  has  reviewed  and  currently  intends to  continue to review
potential acquisition and affiliation  opportunities.  The Company believes that
available  cash  resources,  including  the  proceeds  of  the  offering  of the
Company's  common stock referred to above,  bank  financings and the issuance of
additional   common  stock  would  be  used  to  finance  such  acquisitions  or
affiliations.  There can be no assurance the Company will make an acquisition or
affiliation in 1997.

OTHER MATTERS AND SUBSEQUENT EVENTS

     As  discussed in Note 2 to the  financial  statements,  in February,  1997,
PacifiCare Health Systems, Inc.  ("PacifiCare")  announced that it had completed
the acquisition of FHP International,  Inc. ("FHP").  The Company has a contract
to provide  pharmacy  benefit  services to FHP's  members  (currently  about 2.0
million) through  December 31, 1997.  While FHP is the Company's  largest single
client in terms of membership, its contribution to the company's net revenues is
less than 2% due to the fact that the Company  only  records the fees related to
administering   FHP's  network   prescriptions   and  dispensing  mail  pharmacy
prescriptions.  While the earnings  attributable to the Company's  contract with
FHP presently are material to reported  financial  results,  its contribution to
earnings is substantially  less than the relationship of FHP membership to total
membership.  The Company does not currently provide pharmacy benefit  management
services to  PacifiCare.  The Company has not received  notice that its contract
with FHP will not be extended.

     As previously  disclosed,  the Company  received  notice from New York Life
Insurance Company ("New York Life") that New York Life would exercise its option
to renegotiate  pricing under its agreement  with the Company  pursuant to which
the Company  provides  non-exclusive  pharmacy  benefit  management  services to
certain  group  indemnity  policyholders  of New York Life and certain  contract
holders whose health  benefit plans provide  indemnity-style  benefits for which
New York Life provides  administrative  services  only. The parties have amended
the  agreement,  effective  January 1, 1997.  The  principal  provisions  of the
amendment  are:  (i) an  assignment  of the  agreement  by New York  Life to its
subsidiary,  NYLCare,  (ii) a reduction of rates consistent with current pricing
trends and a waiver by both  parties of their  respective  right to  renegotiate
pricing  prior to January  1,  1999,  and (iii) the  adoption  of the  Company's
ExpressPreferenceSM  drug therapy  management  program as a condition to certain
price  concessions.  The amendment does not affect the Company's  agreement with
NYLCare  relating to health  maintenance  organizations  and other  managed care
organizations owned or managed by NYLCare.

     On March 13, 1997,  the Company  announced that it had reached an agreement
with RightCHOICE Managed Care, Inc. ("RightCHOICE"),  a publicly held subsidiary
of Blue Cross and Blue Shield of  Missouri,  whereby the  Company  will  provide
pharmaceutical  benefit  management  services  to  RightCHOICE.  The three  year
agreement  is effective  March 17,  1997,  and  initially  covers  approximately
500,000  members.  The  agreement  also offers the Company  the  opportunity  to
provide service to an additional 1.4 million members enrolled in plans sponsored
or administered by organizations affiliated with RightCHOICE.

IMPACT OF INFLATION

     Changes  in  the  prices  charged  by  manufacturers   and  wholesalers for
pharmaceuticals  affect the Company's cost of revenues.  To date the Company has
been able to recover  price  increases  from its clients  under the terms of its
agreements.  As a result,  changes in  pharmaceutical  prices have not adversely
affected the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The  significant  accounting  policies  followed  by  Express  Scripts  are
described below. The policies  utilized by the Company in the preparation of the
financial  statements conform to generally accepted accounting  principles,  and
require  management to make estimates and  assumptions  that affect the reported
amounts of assets and  liabilities  at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual amounts could differ from those estimates and assumptions.
 
     PRINCIPLES OF CONSOLIDATION.  The consolidated financial statements include
the accounts of the Company and all majority-owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated.

     FOREIGN CURRENCY TRANSLATION. Adjustments resulting from the translation of
financial  statements  are  reflected as a separate  component of  stockholders'
equity.

     ORGANIZATION AND OPERATIONS.  The Company currently derives the majority of
its revenues,  including claims processing fees, principally from domestic sales
of  prescription  drugs by its mail  pharmacies  and pharmacies in the Company's
nationwide  network.  Effective in January 1996,  the Company  began  processing
claims for clients of its wholly-owned  Canadian  subsidiary,  ESI Canada,  Inc.
("ESI Canada").  Express  Scripts' IVTx division applies managed care principles
to infusion therapy  management.  Through its Practice  Patterns  Science,  Inc.
subsidiary,  the Company offers provider  profiling and disease state management
support  services.  The Company  receives  revenues from sales of eyeglasses and
contact  lenses  and  associated  administrative  fees  to  participants  in the
Company's   managed  vision   programs   operated  by  ESI Vision Care.

     In March of 1992, the Company, originally incorporated in Missouri in 1986,
was  reincorporated  in Delaware and issued an aggregate of 10,500,000 shares of
Class B Common Stock to Sanus Corp. Health Systems ("Sanus") in exchange for the
outstanding  shares of its  common  stock.  Sanus at that  time was an  indirect
subsidiary  of New York Life.  In April 1992,  as a result of a  reorganization,
both the Company  and Sanus  became  direct  subsidiaries  of NYLIFE  HealthCare
Management, Inc. ("NYLIFE").  Sanus has since changed its name to NYLCare Health
Plans, Inc. ("NYLCare). In April 1996, NYLIFE converted 2,990,000 Class B shares
to Class A Common  Stock  and sold  those  shares in a public  offering.  NYLIFE
continues  to own all the  remaining  outstanding  Class B  Common  Stock of the
Company (see Note 9).

       CONTRACTUAL AGREEMENTS. The Company enters into corporate alliances with
certain of its clients whereby shares of the Company's Class A Common Stock are
awarded as advance discounts to the client. For agreements consummated prior to
December 15, 1995, the stock is valued utilizing the quoted market value at the
date the agreement is consummated if the number of shares to be issued is known.
If the number of shares to be issued is contingent upon the occurrence of future
events, the stock is valued utilizing the quoted market value at the date the
contingency is satisfied and the number of shares is determinable.

     In October 1995, the Financial  Accounting  Standards  Board Statement 123,
"Accounting for Stock-Based  Compensation" ("FAS 123"), was issued, the terms of
which are effective for all stock issued to nonemployees  subsequent to December
15, 1995.  FAS 123 requires that all stock issued to  nonemployees  be accounted
for based on the fair value of the  consideration  received or the fair value of
the equity instruments issued instead of the intrinsic value method utilized for
stock issued or to be issued under alliances  entered into prior to December 15,
1995.  The  Company  has  adopted  FAS 123 as it relates to stock  issued  under
alliances  consummated  subsequent to December 15, 1995,  based on fair value at
the date the agreement is consummated.

     Shares  issued  on the  effective  date of the  contractual  agreement  are
considered  outstanding and included in the earnings per share  computation when
issued.  Shares  issuable  upon  the  satisfaction  of  certain  conditions  are
considered  outstanding and included in the earnings per share  computation when
the  conditions  are met.  The value of the  shares of stock  awarded as advance
discounts  is recorded as a deferred  cost and  included  in Other  Assets.  The
deferred cost is recognized in Selling, General and Administrative expenses over
the period of the contract.

     CASH AND CASH EQUIVALENTS.  Cash and cash equivalents  include cash on hand
and  temporary  investments  in money market  funds.  Due to the nature of these
instruments, the carrying amount approximates fair value.

     SHORT-TERM INVESTMENTS.  Short-term investments consist of debt securities
with a maturity of less than one year that the Company has the  positive  intent
and  ability to hold to  maturity  and are  reported at  amortized  cost,  which
approximates fair market value.

     INVENTORIES. Inventories consist of prescription drugs, vision supplies and
medical  supplies  that are stated at the lower of  first-in  first-out  cost or
market.

     PROPERTY AND  EQUIPMENT.  Property and  equipment is carried at cost and is
depreciated using the straight-line  method over estimated useful lives of seven
years for furniture,  five years for equipment and purchased  computer  software
and three years for personal computers.  Leasehold improvements are amortized on
a  straight-line  basis  over the term of the  lease or the  useful  life of the
asset,  if shorter.  Expenditures  for  repairs,  maintenance  and  renewals are
charged to income as incurred. Expenditures which improve an asset or extend its
estimated useful life are capitalized.  When properties are retired or otherwise
disposed of, the related cost and accumulated  depreciation are removed from the
accounts and any gain or loss is included in income.

     SOFTWARE DEVELOPMENT COSTS. Research and development  expenditures relating
to the  development of software to be marketed to clients are charged to expense
until  technological  feasibility  is  established.  Thereafter,  the  remaining
software  production  costs up to the date of general  release to customers  are
capitalized and included as Property and Equipment.  During 1996, 1995 and 1994,
$1,898,000,   $1,084,000  and  $395,000  in  software   development  costs  were
capitalized,  respectively.  Capitalized  software development costs amounted to
$3,377,000  and  $1,479,000  at  December  31,  1996  and  1995,   respectively.
Amortization of the capitalized amounts commences on the date of general release
to  customers  and  is  computed  on  a   product-by-product   basis  using  the
straight-line  method over the remaining  estimated economic life of the product
but not more than five  years.  Reductions,  if any,  in the  carrying  value of
capitalized  software  costs  to net  realizable  value  are  also  included  in
amortization expense. Amortization expense was $136,000 in 1996. No amortization
expense was recorded in 1995 or 1994.

     GOODWILL.  Goodwill is  amortized on a  straight-line  basis over a fifteen
year period.  Amortization expense was $42,000 for each of the three years ended
December 31, 1996, 1995 and 1994.

     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 December 31, 1996 or 1995.

     REVENUE   RECOGNITION.    Revenues   from   dispensing   prescription   and
non-prescription medical products from the Company's mail service pharmacies are
recorded upon shipment.  Revenue from sales of prescription  drugs by pharmacies
in the Company's  nationwide network and pharmacy claims processing revenues are
recognized  when the claims are  processed.  When the Company has an independent
contractual  obligation  to pay its  network  pharmacy  providers  for  benefits
provided to members of its clients' pharmacy benefit plans, the Company includes
payments  from plan  sponsors for these  benefits as net revenue and payments to
these  pharmacy  providers  in  cost  of  revenues.   If  the  Company  is  only
administering the plan sponsors' network pharmacy contracts, the Company records
fees derived from the Company's contracts with the plan sponsors as net revenue.

     COST OF REVENUES.  Cost of revenues includes product costs, pharmacy claims
payments and other direct costs  associated  with dispensing  prescriptions  and
non-prescription  medical products and claims processing  operations,  offset by
fees received from pharmaceutical manufacturers in connection with the Company's
drug purchasing and formulary management programs.

     INCOME TAXES.  The Company accounts for income taxes in accordance with the
provisions of Statement of Financial  Accounting  Standards No. 109, "Accounting
for Income  Taxes"  ("FAS 109").  Under FAS 109,  the deferred tax  provision is
determined under the liability  method.  Under this method,  deferred assets and
liabilities  are recognized  based on temporary  differences  between  financial
statement basis and tax basis of assets and liabilities  using presently enacted
tax rates.

     PRIMARY  EARNINGS  PER SHARE.  Primary  earnings  per share are computed by
dividing  net income by the  weighted  average  number of shares of common stock
outstanding,  including  common  stock  equivalents.  Common  stock  equivalents
include shares issuable upon the assumed exercise of all stock options having an
exercise  price less than the average market price of the common stock using the
treasury stock method.

     EMPLOYEE STOCK-BASED COMPENSATION.  The Company accounts for employee stock
options  in  accordance  with  Accounting  Principles  Board  No.  25 (APB  25),
"Accounting  for Stock Issued to Employees."  Under APB 25, the Company  applies
the intrinsic  value method of  accounting  and,  therefore,  does not recognize
compensation expense for options granted,  because options are only granted at a
price equal to market  value at the time of grant.  During  1996,  Statement  of
Financial  Accounting  Standards No. 123 (FAS 123),  "Accounting for Stock Based
Compensation,"  became  effective  for  the  Company.  FAS  123  prescribes  the
recognition  of  compensation  expense  based  on  the  fair  value  of  options
determined on the grant date.  However,  FAS 123 grants an exception that allows
companies  currently  applying APB 25 to continue using that method. The Company
has,  therefore,  elected to continue  applying the intrinsic value method under
APB 25. For  companies  that choose to continue  applying  the  intrinsic  value
method,  FAS 123  mandates  certain pro forma  disclosures  as if the fair value
method had been utilized (see Note 10).


    2. CONTRACTUAL AGREEMENTS

     On  December  31,  1995,  the  Company  entered  into a ten-year  corporate
alliance with Premier Purchasing Partners,  L.P. (formerly,  American Healthcare
Systems Purchasing Partners, L.P., the "Partnership"),  an affiliate of Premier,
Inc.  ("Premier").  Premier is the alliance of healthcare systems resulting from
the merger in 1995 of American Healthcare  Systems,  Premier Health Alliance and
SunHealth Alliance. Under the terms of the transaction, the Company is Premier's
preferred   vendor  of  pharmacy  benefit   management   services  to  Premier's
shareholder  systems and their managed care  affiliates and will issue shares of
its Class A Common Stock as an  administrative  fee to the Partnership  based on
the  attainment  of  certain  benchmarks,  principally  related to the number of
members receiving the Company's pharmacy benefit  management  services under the
arrangement,  and to the  achievement  of certain joint  purchasing  goals.  The
Company may be required to issue up to 2,500,000  shares to the Partnership over
a period up to the first five years of the agreement if the Partnership  exceeds
all  benchmarks.  Except for  certain  exemptions  from  registration  under the
Securities  Act of 1933 (the "1933 Act"),  any shares issued to the  Partnership
cannot be traded  until  they  have been  registered  under the 1933 Act and any
applicable state securities laws.

     Pursuant to the  agreement,  the Company  issued  227,273 shares of Class A
Common Stock to Premier in May, 1996. The shares were valued at $11,250,000  and
are being amortized over the then remaining term of the agreement.  Amortization
expense amounted to $776,000 in 1996.

     Effective January 1, 1996, the Company executed a multi-year  contract with
The Manufacturers  Life Insurance Company  ("Manulife"),  to introduce  pharmacy
benefit  management  services  in Canada.  Manulife's  Group  Benefits  Division
continues to work with ESI Canada to provide these services.  Under the terms of
the  agreement,  following  a  transitional  period,  the  Company  will  be the
exclusive  third-party  provider  of  pharmacy  benefit  management  services to
Manulife's  Canadian clients.  The Company also will issue shares of its Class A
Common  Stock as an advance  discount  to  Manulife  based upon  achievement  of
certain volumes of Manulife pharmacy claims processed by the Company.  No shares
will be issued  until  after the fourth year of the  agreement  based on volumes
reached in years two through four. The Company  anticipates issuing no more than
237,000  shares  to  Manulife  over a period  up to the  first  six years of the
agreement.  Except for certain  exemptions from registration under the 1933 Act,
any shares issued to Manulife  cannot be traded until they have been  registered
under the 1933 Act and any applicable  state securities laws. In accordance with
the terms of the agreement, no stock was issued in 1996.

     If Manulife has not exercised an early termination option at the end of the
sixth or tenth year of the  agreement,  the Company  will issue at each of those
times a ten-year  warrant as an advance discount to purchase up to approximately
118,000  additional  shares of the Company's Class A Common Stock exercisable at
85% of the market  price at those times.  The actual  number of shares for which
such warrant is to be issued is based on the volume of Manulife  pharmacy claims
processed by the Company in year six and year ten, respectively.

     Pursuant to an agreement with Coventry  Corporation,  an operator of health
maintenance  organizations  located principally in Pennsylvania and Missouri, on
January 3, 1995,  the Company issued 25,000 shares of Class A Common Stock as an
advance discount to Coventry in a private placement. These shares were valued at
$27.38 per share,  the per share  market value of the  Company's  Class A Common
Stock on November 22, 1994, which was the date the agreement was consummated and
the  obligation  of  the  parties  became  unconditional.  No  revision  of  the
consideration for the transaction occurred between November 22, 1994 and January
3, 1995.  The shares  issued to  Coventry  are being  amortized  over a six-year
period.  Amortization  expense was $114,000 in 1996 and 1995. Except for certain
exemptions from  registration  under the 1933 Act, these shares cannot be traded
until  they have been  registered  under the 1933 Act and any  applicable  state
securities laws.

     If Coventry renews the agreement for a second  three-year term, the Company
will issue a ten-year  warrant as an advance  discount to purchase an additional
25,000 shares of the Company's  Class A Common Stock,  exercisable at 90% of the
market  value at the time of renewal.  If the renewal  period is for five years,
the warrant is for 58,000 shares.

     On October 13, 1992, the Company entered into a five-year  arrangement with
FHP,  Inc.  ("FHP")  pursuant  to which the Company  agreed to provide  pharmacy
benefit  services  to  FHP  and  its  members.  FHP  is an  operator  of  health
maintenance  organizations,   principally  in  the  western  United  States.  In
accordance with the agreement,  the Company commenced providing pharmacy benefit
services to FHP and its members on January 4, 1993.

     On the commencement date and pursuant to the agreement,  the Company issued
200,000  shares of its Class A Common  Stock as  advance  discounts  to FHP in a
private  placement.  These shares were valued at $8.25 per share,  the per share
market value of the Company's Class A shares on October 13, 1992,  which was the
date the agreement was  consummated  and the  obligations  of the parties became
unconditional.  No revision of the  consideration  for the transaction  occurred
between  October 13, 1992 and January 4, 1993.  The cost of the shares issued to
FHP is being amortized over a ten-year period. Amortization expense was $165,000
in 1996, 1995 and 1994.

     FHP has the option to renew the agreement for an additional  five years. If
FHP renews the agreement for a second  five-year  term, the Company will issue a
ten-year warrant as an advance discount to purchase an additional 300,000 shares
of the Company's Class A Common Stock, exercisable at 90% of market value at the
time of renewal.

     In February, 1997 PacifiCare Health Systems, Inc. ("PacifiCare")  completed
the acquisition of FHP. At this time, the Company has not been informed  whether
or not  PacifiCare/FHP  will renew the  agreement.  The Company has assessed the
impairment of the unamortized portion of the advance discount in accordance with
its policy on Impairment of Long Lived Assets. In the opinion of management,  no
such impairment existed at December 31, 1996.

    3. RELATED PARTY TRANSACTIONS

     The Company has agreements to provide claims  processing  services and mail
pharmacy  prescription  services  for  NYLCare,  in return for which it receives
processing fees and reimbursement for the contracted cost of the claims. Cost of
revenues from related parties were $122,157,000,  $82,903,000 and $62,839,000 in
1996, 1995 and 1994, respectively.

The amount receivable from or (due to) related parties comprised the following:

     Prior to October 1,  1994,  NYLCare  administered  the  Company's  payroll.
Effective  October 1, 1994,  the Company  provides for its own payroll  services
independent  of  NYLCare.  Prior to January 1,  1995,  consideration  to NYLCare
consisted of an annual fee for such  services.  Effective  January 1, 1995,  the
agreement  with NYLCare was amended such that NYLCare is no longer  obligated to
provide certain administrative  services, and the Company is no longer obligated
to pay an annual fee.

     The  Company is the  exclusive  provider  of  pharmacy  benefit  management
services  to  NYLCare's  managed  healthcare  subsidiaries,  subject  to certain
exceptions.  Currently,  the Company's agreement with NYLCare also provides that
fees  from  drug  manufacturers   whose  products  are  used  in  the  Company's
formularies  related  to  NYLCare  subsidiaries  will be  allocated  100% to the
Company up to $400,000  after January 1, 1995,  and the amount of the annual fee
prior to January 1, 1995, and 75% to NYLCare and 25% to the Company  thereafter.
The Company is a non-exclusive  provider of pharmacy benefit management services
to New York Life Insurance Company's  indemnity  insurance  business,  which has
been transferred to NYLCare. In years prior to 1997 fees from drug manufacturers
with respect to this indemnity  business were allocated 100% to the Company.  In
1997 and later,  the  Company  will share such fees with  NYLCare on a fixed per
script    amount,    conditional    upon   NYLCare    adopting   the   Company's
ExpressPreferenceSM drug therapy management program.

     Such fees allocated to NYLCare were  $7,636,000,  $5,895,000 and $4,320,000
in 1996, 1995 and 1994, respectively, and $3,064,000 in 1996, $2,553,000 in 1995
and $1,874,000 in 1994,  were allocated to the Company and have been  classified
in the accompanying  consolidated statement of operations as a reduction of cost
of revenues.

The  effective  tax rate is  comprised  of a federal rate of 35.0% in 1996,
1995 and 1994,  state  taxes net of federal  benefit  of 4.3%,  3.5% and 3.6% in
1996, 1995 and 1994, respectively; and all other items comprising (0.0%), (0.3%)
and 0.2% in 1996,  1995 and 1994,  respectively.  The effect of foreign taxes on
the effective tax rate for 1996 is immaterial.

The Company made cash payments for federal and state income taxes of
$14,540,000, $7,548,000 and $7,393,000 in 1996, 1995 and 1994, respectively.

    6. COMMITMENTS AND CONTINGENCIES

     The Company leases office and  distribution  facility space under operating
leases.  The primary  leases are for office and  distribution  facilities in St.
Louis,  Missouri,  and Tempe, Arizona. The St. Louis facility is under a 16-year
lease  which  commenced  November  1992,  and the  facility  in Tempe is under a
15-year lease which commenced  November 1993. The Company also leases  satellite
offices for certain other Company  operations for varying periods up to 6 years.
The  aggregate  minimum lease  commitment  is $1,787,000 in 1997,  $1,829,000 in
1998,   $1,809,000  in  1999,  $1,805,000  in  2000,  $1,731,000  in  2001,  and
$11,724,000 in years thereafter.

     For the year ended  December 31, 1996,  approximately  79% of the Company's
pharmaceutical purchases were through one wholesaler.  The Company believes that
other alternative sources are readily available.

     In the  ordinary  course of  business,  there  have  arisen  various  legal
proceedings,  investigations  or claims  pending  against  the  Company  and its
subsidiaries.  The effect of these  actions on future  financial  results is not
subject to reasonable  estimation because considerable  uncertainty exists about
the  outcomes.   Nevertheless,  in  the  opinion  of  management,  the  ultimate
liabilities  resulting  from any such  lawsuits,  investigations  or claims  now
pending will not materially affect the consolidated financial position,  results
of operations or cash flows of the Company.

    7. CREDIT AGREEMENT

     The Company  maintains two  $25,000,000  unsecured lines of credit with two
separate financial  institutions.  One agreement will expire on May 28, 1997 and
the other on October 30, 1997.  Terms of both lines are essentially the same and
are as follows:  interest is charged on the principal  amount  outstanding  at a
rate equal to any of the  following  options  which the Company,  at its option,
shall select:  (i) the bank's  "prime  rate",  (ii) a floating rate equal to the
Bank's  cost of funds  rate  plus 50  basis  points,  or (iii) a fixed  rate for
periods of 30, 60, 90 or 180 days equal to the LIBOR rate plus 50 basis  points.
Fees under these  agreements on any unused portion are charged at ten hundredths
of one percent  per year.  At  December  31,  1996 and 1995,  the Company had no
outstanding  borrowings  under these  agreements,  nor did it borrow any amounts
under these agreements during 1996.

    8. RETIREMENT PLAN

     The Company offers all of its full-time employees a retirement savings plan
under Section 401(k) of the Internal Revenue Code.  Employees may elect to enter
into a written salary  deferral  agreement under which a maximum of 10% of their
salary,  subject to aggregate  limits required under the Internal  Revenue Code,
may be  contributed  to the plan. In 1994,  the Company began matching the first
$1,000 of the employee's  contribution for the year.  Effective January 1, 1996,
the  Company's  match  was  increased  to the  first  $2,000  of the  employee's
contribution  for the year. For the year ended December 1996, 1995 and 1994, the
Company made  contributions  of approximately  $639,000,  $332,000 and $116,000,
respectively.

    9. COMMON STOCK

     The  holders  of Class A Common  Stock  have  one vote per  share,  and the
holders of Class B Common  Stock  have ten votes per  share.  NYLIFE is the sole
holder of Class B Common  Stock.  Class B Common  Stock  converts  into  Class A
Common Stock on a  share-for-share  basis upon transfer  (other than to New York
Life or its  affiliates) and is convertible at any time in the discretion of the
holder.  At December  31,  1996,  NYLIFE and the holders of Class A Common Stock
have control over approximately 89.3% and 10.7%,  respectively,  of the combined
voting power of all classes of Common Stock.

     On May 25,  1994,  the  stockholders  approved an increase in the number of
authorized shares of Class A Common Stock by 10,000,000 shares and the number of
authorized shares of Class B Common Stock by 12,000,000  shares.  This permitted
the  two-for-one  split of common  stock  declared by the Board of  Directors on
March 23,  1994.  The stock split was effected by the  distribution  on June 24,
1994 of one new share of common stock for each share  outstanding  to holders of
record on June 9, 1994. The par value remained at $0.01 per share  following the
split.  This  split  has been  reflected  in the  December  31,  1994  financial
statements by transferring  an amount equal to $73,000 from  additional  paid-in
capital to common stock. All references in the financial statements and in these
notes to the number of common  shares  issued,  the weighted  average  number of
common shares  outstanding,  primary earnings per share amounts and stock option
plan data have been restated to reflect the split.

     In April, 1996 NYLIFE converted 2,990,000 shares of Class B Common Stock to
Class A Common  Stock  and sold the  Class A shares  in a public  offering.  The
Company did not receive any proceeds from the sale of these shares.  The Company
sold an  additional  1,150,000  Class A shares in the same  stock  offering  and
received  net  proceeds of  $52,592,000  after  deducting  expenses  incurred in
connection with the offering.

     As of December 31, 1996,  3,637,000  shares of the Company's Class A Common
Stock have been  reserved for issuance to  organizations  with which the Company
has signed contractual agreements (see Note 2).

   10. STOCK OPTION PLANS

     At December 31, 1996, the Company has three fixed stock-based  compensation
plans, which are described below.

     In April 1992,  the Company  adopted a stock  option plan  amended in 1995,
which provides for the grant of  nonqualified  stock options and incentive stock
options  to  officers  and  key  employees  of  the  Company   selected  by  the
Compensation  Committee  of the Board of  Directors.  Initially,  a  maximum  of
700,000  shares of Class A Common  Stock  could be issued  under the plan.  That
amount increases  annually each January 1, from January 1, 1993 to and including
January 1, 1999 by 70,000 shares, to a maximum of 1,190,000 shares. By unanimous
written  consent dated June 6, 1994, the Board of Directors  adopted the Express
Scripts,  Inc.  1994 Stock  Option  Plan,  also  amended  in 1995.  The plan was
approved by the stockholders in June 1995. Initially,  a total of 210,000 shares
of the Company's Class A Common Stock was reserved for issuance under this plan.
In January  1997,  the Board of  Directors  adopted  amendments  to this plan to
increase  the total  number  of  shares  subject  to the plan to  460,000.  This
amendment  to the 1994 Plan will be put before the  Company's  stockholders  for
approval at the 1997 annual  meeting.  Under either plan,  the exercise price of
the options may not be less than the fair market value of the shares at the time
of grant. Options vest, and may be exercised, at such times as the Committee may
determine, subject to a maximum period of ten years.

     In April  1992,  the  Company  also  adopted a stock  option plan which was
amended  in 1995 and 1996  and  provides  for the  grant of  nonqualified  stock
options to purchase 24,000 shares to each director who is not an employee of the
Company or its  affiliates.  A maximum of 192,000 shares of Class A Common Stock
may be issued  under this plan at a price equal to fair market value at the date
of grant.  Options granted after the 1996 amendment vest over a five-year period
from the date of grant.

     The  Company  applies  APB  Opinion  25  and  related   interpretations  in
accounting for its plans. Accordingly,  no compensation cost has been recognized
for its stock options plans. Had compensation cost for the Company's stock based
compensation  plans been  determined  based on the fair value at the grant dates
for awards under those plans  consistent with the method  prescribed by FAS 123,
the  Company's  net income and earnings per share would have been reduced to the
pro  forma  amounts  indicated  below.  Note  that  due to the  adoption  of the
methodology  prescribed  by FAS 123,  the pro forma  results  shown  below  only
reflect the impact of options  granted in 1996 and 1995.  Because future options
may be granted and vesting occurs over a five year period,  the pro forma impact
shown  for 1996 and 1995 is not  necessarily  representative  of the  impact  in
future years.



                                                  1996             1995
                                                                 
                                            -----------------------------------

Net income                    As reported     $ 26,148,000    $ 18,327,000
                              Pro forma         25,235,000      18,220,000

Primary earnings per share    As reported     $      1.60     $      1.20
                              Pro forma              1.56            1.20


The fair value of options granted (which is amortized to expense over the option
vesting period in determining the pro forma impact), is estimated on the date of
grant using the Black-Scholes multiple option-pricing model with the following
weighted average assumptions:


                                             1996                     1995
                                                                    
                                   -------------------------------------------

Expected life of option                    1-6 years                1-6 years
Risk-free interest rate                    5-6.5%                   5.5-6.9%
Expected volatility of stock               30-50%                   30-50%
Expected dividend yield                    None                     None


     A summary of the status of the Company's  three fixed stock option plans as
of December  31,  1996,  1995 and 1994,  and changes  during the years ending on
those dates is presented below.
