     Each broker-dealer that receives exchange notes for its own account
pursuant to the exchange offer must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange notes. The letter of
transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     This prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of exchange notes
received in exchange for outstanding notes where such outstanding notes were
acquired by such broker-dealer as a result of market-making activities or other
trading activities.

     We have agreed that, for a period of 180 days after the consummation of the
exchange offer, we will make this prospectus available to any broker-dealer for
use in connection with any such resale. See "Plan of Distribution."

     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or determined if this
prospectus is truthful or complete. Any representation to the contrary is a
criminal offense.


                 The date of this prospectus is August 4, 1999

                               PROSPECTUS SUMMARY

     This summary highlights information contained elsewhere in this prospectus
and may not contain all of the information you may consider important. You
should read this entire prospectus carefully. You should also keep in mind the
following points as you read this prospectus:

- - Unless the context otherwise indicates, references in this document to
  "Express Scripts," "we," "us" and "our" refer to Express Scripts, Inc. and its
  subsidiaries. References to "NYLIFE HealthCare" refer to NYLIFE HealthCare
  Management, Inc.

- - Unless we tell you otherwise, all information in this prospectus has been
  adjusted to reflect a two-for-one stock split of our common stock that
  occurred on October 30, 1998

- - Information regarding our relative size is based on estimates of our
  management in light of their experience in the industry

- - Membership counts may not be comparable between us and Diversified
  Pharmaceutical Services, or between us and our competitors, although we
  believe they provide a reasonable estimation of the population we serve

                     SUMMARY OF TERMS OF THE EXCHANGE OFFER

     On June 16, 1999, we completed the private offering of the outstanding
notes. References to "notes" in this prospectus are references to both the
outstanding notes and the exchange notes.

     Express Scripts and the guarantors entered into a registration rights
agreement with the initial purchasers in the private offering in which Express
Scripts and the guarantors agreed to deliver to you this prospectus and Express
Scripts agreed to complete the exchange offer within 220 days after the date of
original issuance of the outstanding notes. You are entitled to exchange in the
exchange offer your outstanding notes for exchange notes which are identical in
all material respects to the outstanding notes except that:

     - the exchange notes have been registered under the Securities Act

     - the exchange notes are not entitled to certain registration rights which
       are applicable to the outstanding notes under the registration rights
       agreement

     - certain contingent interest rate provisions are no longer applicable

The Exchange Offer..............    We are offering to exchange up to $250
                                    million aggregate principal amount of
                                    exchange notes for up to $250 million
                                    aggregate principal amount of outstanding
                                    notes. Outstanding notes may be exchanged
                                    only in integral multiples of $1,000.

Resales.........................    Based on an interpretation by the staff of
                                    the SEC set forth in no-action letters
                                    issued to third parties, we believe that the

                         SUMMARY OF TERMS OF THE NOTES

Issuer..........................    Express Scripts, Inc.

Securities Offered..............    $250 million aggregate principal amount of
                                    9 5/8% Senior Notes Due 2009.

Maturity........................    June 15, 2009.

Interest Rate...................    9 5/8% per year.

Interest Payment Dates..........    June 15 and December 15 of each year,
                                    commencing December 15, 1999.

Ranking.........................    The notes are senior unsecured obligations
                                    and have the same right of payment as all
                                    our existing and future senior unsecured
                                    indebtedness. The notes are effectively
                                    subordinated to all our existing and future
                                    secured indebtedness to the extent of the
                                    assets securing that indebtedness.

Guarantees......................    Certain of our existing and future domestic
                                    subsidiaries have guaranteed the notes with
                                    senior unsecured guarantees of payment.
                                    These guarantees are effectively
                                    subordinated to all of those subsidiaries'
                                    existing and future secured indebtedness to
                                    the extent of the assets securing that
                                    indebtedness.

Optional Redemption.............    We cannot redeem the notes until June 15,
                                    2004, except as described immediately below.
                                    Thereafter, we can redeem some or all of the
                                    notes at the redemption prices listed under
                                    the heading "Description of the
                                    Notes -- Optional Redemption" in this
                                    prospectus, plus accrued interest.

Optional Redemption After Public
  Equity Offerings..............    At any time (which may be more than once)
                                    before June 15, 2002, we can choose to
                                    redeem up to 35% of the original principal
                                    amount of the notes (including the original
                                    principal amount of any additional notes)
                                    with money that we raise in public equity
                                    offerings, as long as:

                                    - we pay to holders of the notes a
                                      redemption price of 109.625% of the
                                      principal amount of the notes we redeem,
                                      plus accrued interest

                                    - we redeem the notes within 120 days of
                                      completing the public equity offering

                                    - at least 65% of the original principal
                                      amount of notes (including the original
                                      principal amount of any additional notes)
                                      issued remains outstanding afterwards

Change of Control Offer.........    If we go through a change of control, we
                                    must give holders of the notes the
                                    opportunity to sell to us their notes at a
                                    purchase price of 101% of their principal
                                    amount, plus accrued interest, unless we
                                    have previously provided to the trustee
                                    under the indenture governing the notes an
                                    irrevocable notice of redemption to redeem
                                    all outstanding notes at a time when
                                        6
<PAGE>   11

                                    such redemption is permitted under the
                                    indenture. See "Description of the
                                    Notes -- Change of Control".

Certain Covenants...............    The indenture governing the notes contains
                                    covenants that limit our ability and that of
                                    our subsidiaries to:

                                    - incur additional indebtedness

                                    - pay dividends or distributions on, or
                                      redeem or repurchase, our capital stock

                                    - make investments

                                    - issue or sell capital stock of
                                      subsidiaries

                                    - engage in transactions with affiliates

                                    - create liens on our assets

                                    - transfer or sell assets

                                    - restrict dividend or other payments to us

                                    - consolidate, merge or transfer all or
                                      substantially all of our assets and the
                                      assets of subsidiaries

                                    - engage in unrelated businesses

                                    These covenants are subject to important
                                    exceptions and qualifications, which are
                                    described under "Description of the
                                    Notes -- Covenants."

                                    After the notes receive an investment grade
                                    rating by both S&P and Moody's, we and our
                                    subsidiaries will no longer be required to
                                    comply with some of these covenants. See
                                    "Description of the Notes -- Covenant
                                    Removal."

Exchange Offer; Registration
Rights..........................    Under a registration rights agreement we
                                    executed as part of this offering, we have
                                    agreed to:

                                      enabling the holders of the notes to
                                      exchange the notes for publicly registered
                                      notes with identical terms

                                    - use our reasonable best efforts to cause
                                      the registration statement to become
                                      effective within 180 days after the issue
                                      date of the notes

                                    - consummate the exchange offer no later
                                      than 220 days after the date of original

                                    - use our reasonable best efforts to file a
                                      shelf registration statement for the
                                      resale of the notes if we cannot effect an
                                      exchange offer within the time periods
                                      listed above and in some other
                                      circumstances

                                    We will pay additional interest on the notes
                                    if we do not comply with our obligations
                                    under the registration rights agreement. See
                                    "Description of the Notes -- Registered

                                EXPRESS SCRIPTS

     We are the largest pharmacy benefit management company, commonly referred
to as a PBM, independent of pharmaceutical manufacturer or drug store ownership
in North America. PBMs coordinate the distribution of outpatient pharmaceuticals
through a combination of benefit management services, including retail drug card
programs and mail pharmacy services. We provide these services for health care
payors. We believe our independence from pharmaceutical manufacturer ownership
allows us to make unbiased formulary recommendations to our clients, balancing
both clinical efficacy and cost. We also believe our independence from drug
store ownership allows us to construct a variety of convenient and
cost-effective retail pharmacy networks for our clients, without favoring any
particular pharmacy chain.

     We are the third largest PBM in North America in terms of total members,
and we have one of the largest managed care membership bases of any PBM. Before
1998, our growth was driven almost exclusively by our ability to expand our
product offerings and increase our client and membership base through internally
generated growth. From 1992 through 1997, our net revenues and net income
increased at compound annual growth rates of 58% and 49%, respectively. While
our internal growth strategy remains a major focus, we have recently
complemented our internal growth strategy with two substantial acquisitions. In
April 1998, we acquired ValueRx, and in April 1999, we acquired Diversified
Pharmaceutical Services, or DPS. These acquisitions added to the scale of our
membership base, broadened our product offerings and enhanced our clinical
capabilities, systems and technologies. On a pro forma basis including our
recent debt and equity offerings, our net revenues and EBITDA for the twelve
month period ending March 31, 1999 would have been approximately $3.6 billion
and $241.7 million, respectively.

     As of March 31, 1999, after giving effect to the DPS acquisition, we would
have served approximately 47 million members, including 10 million members under
DPS's contract with United HealthCare which will terminate without renewal on
May 31, 2000. Besides United HealthCare, some of our other large clients include
Aetna U.S. Healthcare, Oxford Health Plans and the State of New York Empire Plan
Prescription Drug Program.

     Our PBM services are primarily delivered through networks of retail
pharmacies that are under non-exclusive contract with us and through five mail
pharmacy service centers that we own and operate. Our largest retail pharmacy
network includes more than 52,000 retail pharmacies, representing more than 99%
of all retail pharmacies in the United States. In 1998, including ValueRx and
DPS on a pro forma basis, we processed approximately 284 million pharmacy claims
with estimated total drug spending of approximately $10 billion.
                            ------------------------

     We were incorporated in Missouri in 1986 and reincorporated in Delaware in
1992. Our principal executive offices are located at 13900 Riverport Drive,
Maryland Heights, Missouri 63043, and our phone number is (314) 770-1666.

acquisition of DPS.

                                  RISK FACTORS

     In addition to the other information in this prospectus, the following
factors may be important to you.


IF YOU DO NOT PARTICIPATE IN THE EXCHANGE OFFER, YOU WILL CONTINUE TO BE SUBJECT
TO TRANSFER RESTRICTIONS



     If you do not exchange your outstanding notes in the exchange offer, you
will continue to be subject to restrictions on transfer of your outstanding
notes. We did not register the outstanding notes under the federal or any state
securities laws, and we do not intend to register them following the exchange
offer. As a result, the outstanding notes may only be transferred in limited
circumstances under the securities laws. In addition, to the extent outstanding
notes are tendered and accepted in the exchange offer, the trading market, if
any, for the outstanding notes would be adversely affected. As a result, after
the exchange offer, you may have difficulty selling your outstanding notes.



YOU MUST FOLLOW THE EXCHANGE OFFER PROCEDURES CAREFULLY IN ORDER TO RECEIVE THE
EXCHANGE NOTES



     If you do not follow the procedures described herein, you will not receive
exchange notes. The exchange notes will be issued to you in exchange for your
outstanding notes only after timely receipt by the exchange agent of:



     - your outstanding notes and either:



     - a properly completed and executed letter of transmittal and all other
       required documentation or



     - a book-entry delivery by transmittal of an agent's message through DTC



     If you want to tender your outstanding notes in exchange for exchange
notes, you should allow sufficient time to ensure timely delivery. No one is
under any duty to give you notification of defects or irregularities with
respect to tenders of outstanding notes for exchange. For additional
information, please refer to the sections captioned "The Exchange Offer" and
"Plan of Distribution" in this prospectus.


FAILURE TO INTEGRATE VALUERX AND DPS COULD ADVERSELY AFFECT OUR BUSINESS

     Our acquisitions of ValueRx and DPS have significantly increased our
membership base and the complexity of our operations. In light of both
acquisitions, we have developed and begun to implement an integration plan to
address items such as:

     - retention of key employees

     - consolidation of administrative and other duplicative functions

     - coordination of sales, marketing, customer service and clinical functions

     - systems integration

     - new product and service development

     - client retention and other items

     While we have achieved many of our integration goals to date with respect
to the acquisition of ValueRx, some significant integration challenges remain,
including the

                                        9
<PAGE>   14

complete integration of our information technology systems. We cannot provide
any assurance that our integration plan for ValueRx will successfully address
all aspects of our operations, or that we will continue to achieve our
integration goals. In the case of DPS, we cannot provide any assurance that our
integration plan will address all relevant aspects of DPS's business or that we
will be able to implement our integration plan successfully. In addition, we
assumed specific financial targets, including for revenues, earnings before
interest, taxes, depreciation and amortization, and cash flow, when deciding to
purchase ValueRx and DPS, and we cannot provide any assurance that we will be
able to achieve our targets. Many clients have relatively short-term contracts,
and we cannot provide any assurance that we will be able to achieve our client
retention targets. Finally, although we conducted an extensive investigation in
evaluating our acquisitions of ValueRx and DPS, it is possible that we failed to
uncover or appropriately address material problems with ValueRx's or DPS's
operations or financial condition, or failed to discover contingent liabilities.
Any of the foregoing could materially adversely affect our results of operations
or financial condition.

OUR LEVERAGE AND DEBT SERVICE OBLIGATIONS COULD IMPEDE OUR OPERATIONS AND
FLEXIBILITY

     We have substantial leverage, which means that the amount of our
outstanding debt will be large compared to the net book value of our assets, and
we will have substantial repayment obligations and interest expense. As of March
31, 1999, on a pro forma basis including our recent debt and equity offerings,
we would have had total consolidated debt of approximately $749 million (before
giving effect to the repayment of $25 million of our indebtedness with available
cash). We and our subsidiaries may incur additional indebtedness in the future.

     Our level of debt and the limitations imposed on us by our debt agreements
could have important consequences to you, including the following:

     - we will have to use a substantial portion of our cash flow from
       operations for debt service rather than for our operations

     - we may not be able to obtain additional debt financing for future working
       capital, capital expenditures or other corporate purposes

     - some of the debt under our $1.05 billion credit facility may be at a
       variable interest rate, making us vulnerable to increases in interest
       rates

     - we could be less able to take advantage of significant business
       opportunities, such as acquisition opportunities, and react to changes in
       market or industry conditions

     - we could be more vulnerable to general adverse economic and industry
       conditions

     - we may be disadvantaged compared to competitors with less leverage

     Furthermore, our ability to satisfy our obligations, including our debt
service requirements, will be dependent upon our future performance. Factors
which could affect our future performance include, without limitation,
prevailing economic conditions and financial, business and other factors, many
of which are beyond our control and which affect our business and operations.

     For more details, see "Description of the Notes."

                                       10
<PAGE>   15

THE NOTES ARE EFFECTIVELY SUBORDINATED TO ALL OUR SECURED INDEBTEDNESS

     The notes and the guarantees are effectively subordinated to all our
existing and future secured indebtedness to the extent of the value of the
assets securing that indebtedness. In connection with our acquisitions of
ValueRx and DPS, we incurred approximately $890 million of indebtedness which is
secured by the stock or other equity interests of each of our existing and
subsequently acquired domestic subsidiaries, excluding Practice Patterns
Science, Great Plains Reinsurance, ValueRx of Michigan, Diversified NY IPA and
Diversified Pharmaceutical Services (Puerto Rico). This indebtedness is
currently funded under our $1.05 billion credit facility with a bank syndicate
led by Credit Suisse First Boston and Bankers Trust Company. At March 31, 1999,
on a pro forma basis including our recent debt and equity offerings, the
aggregate amount of our and our subsidiaries' secured indebtedness, excluding
trade payables, which the notes and the guarantees would have been effectively
subordinated to was $500 million (before giving effect to the repayment of
approximately $25 million of our indebtedness with available cash). If we are
unable to meet our obligations under the credit facility, these creditors could
exercise their rights as a secured party and take possession of the pledged
capital stock of these subsidiaries. This would materially adversely affect our
results of operations and financial condition. We and our subsidiaries may incur
additional indebtedness in the future, subject to limitations contained in the
instruments governing our and our subsidiaries existing indebtedness. This
indebtedness may be secured.

FAILURE TO MANAGE AND MAINTAIN INTERNAL GROWTH COULD ADVERSELY AFFECT
OUR BUSINESS

     We have experienced rapid internal growth over the past several years. Our
ability to effectively manage and maintain this internal growth will require
that we continue to improve our financial and management information systems as
well as identify and retain key personnel. We can provide no assurance that we
will successfully meet these requirements or that we will have access to
sufficient capital to do so. Our internal growth is also dependent upon our
ability to attract new clients and achieve growth in the membership base of our
existing clients. If we are unable to continue our client and membership growth,
our results of operations and financial position could be materially adversely
affected.

COMPETITION IN THE PBM INDUSTRY COULD REDUCE OUR CLIENT MEMBERSHIP AND OUR
PROFIT MARGINS

     Pharmacy benefit management is a very competitive business. Our competitors
include several large and well-established companies which may have greater
financial, marketing and technological resources than we do. One major
competitor in the PBM business, Merck-Medco Managed Care, is owned by Merck &
Co., a pharmaceutical manufacturer. Another major competitor, PCS, is owned by
Rite-Aid, a large retail pharmacy chain. Both of these competitors may possess
purchasing or other advantages over us by virtue of their ownership, and could
succeed in taking away some of our clients. Consolidation in the PBM industry
may also lead to increased competition among a smaller number of large PBM
companies. We also face competition from Internet-based providers of
pharmaceuticals such as Drugstore.com and PlanetRx.com. We cannot predict what
effect, if any, these competitors may have on the marketplace or on our
business.

     Over the last several years intense competition in the marketplace has
caused many PBMs, including us, to reduce the prices charged to clients for core
services and share a

                                       11
<PAGE>   16

larger portion of the formulary fees and related revenues received from drug
manufacturers with clients. Increased price competition could reduce our profit
margins and have a material adverse effect on our results of operations.

FAILURE TO RETAIN KEY CLIENTS AND NETWORK PHARMACIES COULD ADVERSELY AFFECT
OUR BUSINESS AND LIMIT OUR ACCESS TO RETAIL PHARMACIES

     We currently provide PBM services to approximately 8,500 clients, including
several large clients. Our contracts with clients generally do not have terms of
longer than three years and in some cases are terminable by either party on
relatively short notice. Our larger clients generally distribute requests for
proposals in advance of the expiration of their contracts. If several of these
large clients elect not to extend their relationship with us, and we are not
successful in generating sales to replace the lost business, our future business
and operating results could be materially adversely affected. In addition, we
believe the managed care industry is undergoing substantial consolidation, and
some of our managed care clients could be acquired by another party that is not
our client. In this case, our client may not renew its PBM contract with us.

     With the completion of our acquisition of DPS, United HealthCare became our
largest client. With approximately 10 million members, United HealthCare
accounts for approximately 22% of our membership base. DPS's contract with
United HealthCare will expire on May 31, 2000, and United HealthCare has
indicated it will be moving to another provider at that time. In our financial
analysis of the DPS acquisition, we assumed United HealthCare would not renew
its contract. However, if we are unable to reduce our costs on a basis
commensurate with our expectations and manage the transition of this large
client to another provider both efficiently and effectively, the termination of
this contract may materially adversely affect our business and results of
operations.

     Our largest national provider network consists of more than 52,000 retail
pharmacies, which represent more than 99% of the retail pharmacies in the United
States. However, the top 10 retail pharmacy chains represent approximately 41%
of the 52,000 pharmacies, with pharmacy chains representing even higher
concentrations in selected areas of the United States. Our contracts with retail
pharmacies, which are non-exclusive, are generally terminable by either party on
relatively short notice. If one or more of the top pharmacy chains elects to
terminate its relationship with us, our members' access to retail pharmacies and
our business could be significantly impaired. In addition, Rite-Aid recently
acquired one of our major PBM competitors, and other large pharmacy chains
either own PBMs today or could attempt to acquire a PBM in the future. Ownership
of PBMs by retail pharmacy chains could have material adverse effects on our
relationships with these pharmacy chains and on our business and results of
operations.

LOSS OF RELATIONSHIPS WITH PHARMACEUTICAL MANUFACTURERS AND CHANGES IN THE
REGULATION OF DISCOUNTS AND REBATES PROVIDED TO US BY PHARMACEUTICAL
MANUFACTURERS COULD DECREASE OUR PROFITS

     We maintain contractual relationships with numerous pharmaceutical
manufacturers which provide us with:

     - discounts at the time we purchase the drugs to be dispensed from our mail
       pharmacies

     - rebates based upon sales of drugs from our mail pharmacies and through
       pharmacies in our retail networks

                                       12
<PAGE>   17

     - administrative fees based upon the development and maintenance of
       formularies which include the particular manufacturer's products

These fees are all commonly referred to as formulary fees or formulary
management fees.

     We also provide various services for, or services which are funded wholly
or partially by, pharmaceutical manufacturers. These services include:

     - compliance programs, which involve instruction and counseling of patients
       concerning the importance of compliance with the drug treatment regimen
       prescribed by their physician

     - therapy management programs, which involve education of patients having
       specific diseases, such as asthma and diabetes, concerning the management
       of their condition

     - market research programs in which we provide information to manufacturers
       concerning drug utilization patterns

These arrangements are generally terminable by either party on relatively short
notice. If several of these arrangements are terminated or materially altered by
the pharmaceutical manufacturers, our operating results could be materially
adversely affected. In addition, formulary fee programs, as well as some of the
services we provide to the pharmaceutical manufacturers, have been the subject
of debate in federal and state legislatures and various other public forums.
Changes in existing laws or regulations, changes in interpretations of existing
laws or regulations or the adoption of new laws or regulations relating to any
of these programs, may materially adversely affect our business.

     Patents covering many brand name drugs that currently have substantial
market share will expire over the next several years, and generic drugs will be
introduced that may substantially reduce the market share of these brand name
drugs. Manufacturers of generic drugs do not generally offer incentive payments
on their drugs to PBMs in the form of discounts, rebates or other formulary
fees. Although we expect new drugs with patent protection to be introduced in
the future, we can provide no assurance these drugs will capture a significant
share of the market such that our incentive payment revenues will not be
reduced.

PENDING AND FUTURE LITIGATION COULD MATERIALLY AFFECT OUR RELATIONSHIPS WITH
PHARMACEUTICAL MANUFACTURERS OR SUBJECT US TO SIGNIFICANT MONETARY DAMAGES

     Since 1993, over 100 separate lawsuits have been filed by retail pharmacies
against drug manufacturers, wholesalers and PBMs challenging brand name drug
pricing practices under various state and federal antitrust laws. Some of these
lawsuits were consolidated into a nationwide class action, while others remained
as individual suits. The class action defendants have either settled the claims
against them or have had the claims dismissed. Several of the individual suits
are ongoing. We are not a party to any of these proceedings, and to date we do
not believe any of the related settlements have had a material adverse effect on
our business. However, we cannot provide any assurance that the terms of the
settlements will not materially adversely affect us in the future or that we
will not be made a party to any separate lawsuit. In addition, we cannot predict
the outcome or possible ramifications to our business of the cases in which the
plaintiffs are trying their claims separately.

     Our PBM operations, including the dispensing of pharmaceutical products by
our mail pharmacies, the services rendered in connection with our formulary
management and

                                       13
<PAGE>   18

informed decision counseling services and the products and services provided in
connection with our infusion therapy programs, including the associated nursing
services, have subjected us and may subject us in the future to litigation and
liability for damages. We believe our insurance protection is adequate for our
present operations, but we cannot provide any assurance that we will be able to
maintain our professional and general liability insurance coverage in the future
or that insurance coverage will be available on acceptable terms to cover any or
all potential product or professional liability claims. A successful product or
professional liability claim in excess of our insurance coverage could have a
material adverse effect on our business.

LIMITATIONS ON REPURCHASES OF NOTES UPON A CHANGE IN CONTROL

     The indenture provides that, upon the occurrence of a change in control, we
will be required to make an offer to purchase all of the notes at a price in
cash equal to 101% of their aggregate principal amount, plus accrued and unpaid
interest, if any, to the date of purchase unless we have provided to the trustee
under the indenture governing the notes an irrevocable notice of redemption to
redeem all of the outstanding notes at a time when such redemption is permitted
under the indenture. Events involving a change in control could result in
acceleration of our $1.05 billion credit facility or in acceleration of, or a
similar repurchase obligation with respect to, other indebtedness of ours. We
cannot be sure that in the event of a change in control we would have sufficient
funds to purchase all notes tendered.

     Our failure to purchase notes would result in a default under the indenture
and, pursuant to cross-default provisions under our $1.05 billion credit
facility, a default under the credit facility as well, which would permit the
trustee under the indenture or the holders of at least 25% in principal amount
of the outstanding notes, or the lenders under our $1.05 billion credit
facility, to declare the respective principal and accrued but unpaid interest to
be due and payable.

     Likewise, the failure to repay the indebtedness under our $1.05 billion
credit facility, if accelerated, would also constitute an event of default under
the indenture, which could result in an acceleration of the notes. In the event
of a change of control, we cannot be sure that we would have the ability to
refinance our $1.05 billion credit facility or have sufficient assets to satisfy
all of our obligations under our $1.05 billion credit facility and the notes.
The provisions relating to a change in control included in the indenture may
increase the difficulty of a potential acquirer obtaining control of us. For
more details, see "Description of the Notes -- Change of Control."

CHANGES IN STATE AND FEDERAL REGULATIONS COULD RESTRICT OUR ABILITY TO CONDUCT
OUR BUSINESS

     Numerous state and federal laws and regulations affect our business and
operations. These laws and regulations include, but are not necessarily limited
to:

     - health care fraud and abuse laws and regulations, which prohibit illegal
       referral and other payments

     - Employee Retirement Income Security Act of 1974 and related regulations,
       which regulate many health care plans

     - mail pharmacy laws and regulations

     - privacy and confidentiality laws and regulations

                                       14
<PAGE>   19

     - proposed comprehensive state PBM regulatory legislation

     - consumer protection laws and regulations

     - pharmacy network access laws, including "any willing provider" and "due
       process" legislation, that regulate aspects of our pharmacy network
       contracts

     - legislation imposing benefit plan design restrictions, which limit how
       our clients can design their drug benefit plans

     - various licensure laws, such as managed care and third party
       administrator licensure laws

     - drug pricing legislation, including "most favored nation" pricing and
       "unitary pricing" legislation

     - Medicare prescription drug coverage proposals

     - other Medicare and Medicaid reimbursement regulations

     - potential regulation of the PBM industry by the U.S. Food and Drug
       Administration

     We believe we are operating our business in substantial compliance with all
existing legal requirements material to the operation of our business. There
are, however, significant uncertainties regarding the application of many of
these legal requirements to our business, and we cannot provide any assurance
that a regulatory agency charged with enforcement of any of these laws or
regulations will not interpret them differently or, if there is an enforcement
action brought against us, that our interpretation would prevail. In addition,
there are numerous proposed health care laws and regulations at the federal and
state levels, many of which could materially affect our ability to conduct our
business or adversely affect our results of operations. We are unable to predict
what additional federal or state legislation or regulatory initiatives may be
enacted in the future relating to our business or the health care industry in
general, or what effect such legislation or regulations might have on us. We
also cannot provide any assurance that federal or state governments will not
impose additional restrictions or adopt interpretations of existing laws that
could have a material adverse effect on our business or results of operations.

EFFORTS TO REDUCE HEALTH CARE COSTS AND ALTER HEALTH CARE FINANCING PRACTICES
COULD ADVERSELY AFFECT OUR BUSINESS

     Efforts are being made in the United States to control health care costs,
including prescription drug costs, in response to, among other things, increases
in prescription drug utilization rates and drug prices. If these efforts are
successful or if prescription drug utilization rates were to decrease
significantly, our business and results of operations could be materially
adversely affected.

     We have designed our business to compete within the current structure of
the U.S. health care system. Changing political, economic and regulatory
influences may affect health care financing and reimbursement practices. If the
current health care financing and reimbursement system changes significantly,
our business could be materially adversely affected. Congress is currently
considering proposals to reform the U.S. health care system. These proposals may
increase governmental involvement in health care and PBM services, and otherwise
change the way our clients do business. Health care organizations may react to
these proposals and the uncertainty surrounding them by reducing or delaying
purchases of cost control mechanisms and related services that we provide. We
cannot predict what

                                       15
<PAGE>   20

effect, if any, these proposals may have on our business. Other legislative or
market-driven changes in the health care system that we cannot anticipate could
also materially adversely affect our business.

FAILURE TO SUCCESSFULLY ADDRESS THE YEAR 2000 ISSUE COULD ADVERSELY AFFECT OUR
BUSINESS

     Our business relies heavily on computers and other information systems
technology. In 1995, we began addressing the "year 2000" issue, which generally
refers to the inability of computer systems to properly recognize calendar dates
beyond December 31, 1999.

     We believe that with appropriate modifications to our existing computer
systems, updates by our vendors and trading partners and conversion to new
software in the ordinary course of our business, the year 2000 issue will not
pose material operational problems for us. However, if the conversions are not
completed in a proper and timely manner by all affected parties, or if our logic
for communicating with noncompliant systems is ineffective, the year 2000 issue
could result in material adverse operational and financial consequences to us.
We cannot provide any assurance that our efforts, or those of our vendors and
trading partners, will be successful in addressing the year 2000 issue. In
addition, while DPS has represented to us that it has implemented a year 2000
plan for upgrading its computer systems and communicated with its vendor/trading
partners regarding these partners' year 2000 compliance, we cannot predict
whether this plan will adequately address all of DPS's year 2000 issues or
whether DPS's vendors/trading partners will adequately address their year 2000
issues. Failure by DPS or its vendors/trading partners to adequately address the
year 2000 issue could have a material adverse effect on our business and results
of operations.

LOSS OF KEY MANAGEMENT COULD ADVERSELY AFFECT OUR BUSINESS

     Our success is materially dependent upon our key managers and, in
particular, upon the continued services of Barrett A. Toan, our President and
Chief Executive Officer. Our future operations could be materially adversely
affected if the services of Mr. Toan cease to be available. We and Mr. Toan are
parties to an employment agreement which currently extends to March 31, 2002,
and which automatically extends for an additional one year on April 1, 2001, and
on each April 1 thereafter unless either party gives notice of termination at
least 30 days prior to such April 1. As of the date hereof, neither we nor Mr.
Toan has given this notice.

NEW YORK LIFE INSURANCE COMPANY CAN CONTROL OUR BUSINESS AND LIMIT OUR
ABILITY TO ENTER INTO SELECTED BUSINESS TRANSACTIONS

     We have two classes of authorized common stock: Class A and Class B common
stock. Our Class B common stock is entirely owned by NYLIFE HealthCare, an
indirect subsidiary of New York Life Insurance Company. Each share of our Class
A common stock has one vote per share, and each share of our Class B common
stock has ten votes per share. After giving effect to our recent equity
offering, NYLIFE HealthCare will have approximately 86.9% of the combined voting
power of our common stock. NYLIFE HealthCare could reduce its Class B common
stock ownership to represent slightly less than 10% of the total outstanding
shares of our common stock and still control a majority of the voting power of
our common stock. In addition, NYLIFE HealthCare could sell all of our common
stock held by it in a negotiated transaction and such sale would not

                                       16
<PAGE>   21

constitute a Change of Control under the indenture governing the notes. Without
regard to the votes of our public stockholders, NYLIFE HealthCare can:

     - elect or remove all our directors

     - amend our certificate of incorporation, except where the separate
       approval of the holders of our Class A common stock is required by law

     - accept or reject a merger, sale of assets or other major corporate
       transaction

     - accept or reject any proposed acquisition of us

     - determine the amount and timing of dividends paid to itself and holders
       of our Class A common stock

     - except in limited circumstances, control our management and operations
       and decide all matters submitted for a stockholder vote

     Our Class B common stock will automatically convert into the same number of
shares of our Class A common stock upon transfer by NYLIFE HealthCare to any
entity other than New York Life or an affiliate of New York Life or otherwise at
the option of NYLIFE HealthCare. We cannot assure you, however, that our Class B
common stock would automatically convert into our Class A common stock if New
York Life were to transfer the stock of NYLIFE HealthCare to someone who is not
an affiliate of New York Life.

THERE IS NO PUBLIC MARKET FOR THE NOTES

     The notes are a new issue of securities for which there is currently no
trading market. As a result, we cannot assure you that a market will develop for
the notes or that you will be able to sell your notes. If a market were to
exist, the notes might trade at prices higher or lower than their initial
offering price. The trading price would depend on many factors, such as
prevailing interest rates and the market for similar securities, general
economic conditions and our financial condition, performance and prospects.
Historically, the market for non-investment grade debt has been subject to
disruptions that have caused substantial fluctuation in the prices of these
securities. The market for the notes may be subject to these disruptions, which
could have an adverse effect on your investment. You should be aware that you
may be required to bear the financial risk of an investment in the notes for an
indefinite period of time. We do not intend to apply for listing or quotation of
the notes; however, the notes are eligible for trading in The Portal(SM) Market.

                                USE OF PROCEEDS

     The exchange offer is intended to satisfy our obligations under the
registration rights agreement that we entered into in connection with the
private offering of the outstanding notes. We will not receive any cash proceeds
from the issuance of the exchange notes. In consideration for issuing the
exchange notes as contemplated in this prospectus, we will receive in exchange a
like principal amount of outstanding notes, the terms of which are identical in
all material respects to the exchange notes. The outstanding notes surrendered
in exchange for the exchange notes will be retired and canceled and cannot be
reissued. Accordingly, issuance of the exchange notes will not result in any
change in our capitalization.

     We used the net proceeds from the private offering of the outstanding notes
to repay a portion of the Term B borrowings under our $1.05 billion credit
facility used by us to finance the acquisition of DPS. At the time of such
repayment, such borrowings bore interest at a rate of 8.42% per annum.

- -------------------------
(1) Earnings per share and weighted average shares outstanding have been
    restated to reflect the two-for-one stock split effective October 30, 1998.

(2) Includes our acquisition of ValueRx effective April 1, 1998. Also includes a
    corporate restructuring charge in 1998 of $1,651, $1,002 after tax, related
    to our managed vision business. Excluding this restructuring charge, our
    basic and diluted earnings per share would have been $1.32 and $1.30,
    respectively.

(3) Drug spending is a measure of the gross aggregate dollar value of drug
    expenditures of all programs managed by us. The difference between drug
    spending and revenue reported by us is the combined effect of excluding from
    reported revenues:

    - the drug ingredient cost for those clients that have established their own
      pharmacy networks

    - the expenditures for drugs for companies on formulary-only programs
      managed by us

    - the co-pay portion of drug expenditures that are the responsibility of
      members of health plans serviced by us

    Therefore, drug spending provides a common basis to compare the drug
    expenditures managed by a company given differences in revenue recognition.

(4) EBITDA is earnings before interest, taxes, depreciation and amortization, or
    operating income plus depreciation and amortization. EBITDA is presented
    because it is a widely accepted indicator of a company's ability to incur
    and service indebtedness. EBITDA, however, should not be considered as an
    alternative to net income as a measure of operating performance or an
    alternative to cash flow as a measure of liquidity. In addition, our
    definition of EBITDA may not be comparable to that reported by other
    companies.

(5) The ratio of earnings to fixed charges is calculated by dividing income
    (loss) before income taxes plus fixed charges, which consist of interest
    expense, capitalized interest, amortization of deferred financing fees and
    the portions of rental expenses representative of the interest expense
    component by fixed charges. The pro forma ratio earnings to fixed charges
    for the three months ended March 31, 1999, for the three months ended March
    31, 1998, and the year ended December 31, 1998 is 3.0x, 2.2x and 2.3x,
    respectively.

           UNAUDITED CONSOLIDATED CONDENSED PRO FORMA FINANCIAL DATA

     The following unaudited consolidated condensed pro forma statement of
operations combines the historical statement of operations of us, Value Health,
Inc., Managed Prescription Network, Inc., together comprising the business known
as ValueRx, and DPS for the year ended December 31, 1998, for the three months
ended March 31, 1998, and the three months ended March 31, 1999. On April 1,
1998, we consummated the acquisition of ValueRx. Therefore, the financial
information of ValueRx is included in our consolidated statement of operations
subsequent to April 1, 1998. The unaudited consolidated condensed pro forma
statement of operations has been prepared to reflect the acquisitions of ValueRx
and DPS and the related financings, including our recent debt and equity
offerings and the use of the net proceeds from these offerings, and the use of
$25 million of our cash to repay some of our indebtedness, all as if these
events had occurred on January 1, 1998. Any cost savings we may realize in
connection with the integration of DPS are not reflected in the pro forma
presentation.

     The following unaudited consolidated condensed pro forma balance sheet
combines the historical consolidated balance sheet of us and DPS as of March 31,
1999. The unaudited consolidated condensed pro forma balance sheet has been
prepared to reflect the acquisition of DPS and the related financings, including
our recent debt and equity offerings and the use of the net proceeds from these
offerings, and the use of $25 million of our cash to repay some of our
indebtedness, all as if these events had occurred on March 31, 1999.

     The detailed assumptions used to prepare the unaudited consolidated
condensed pro forma financial data are contained in the notes to the unaudited
consolidated condensed pro forma financial data. The unaudited consolidated
condensed pro forma financial data reflects the use of the purchase method of
accounting for the acquisitions of ValueRx and DPS. Under the purchase method of
accounting, the basis of accounting for the acquired assets and liabilities is
based upon their fair values at the date of acquisition.

     The pro forma adjustments represent our preliminary determination based
upon available information and assumptions which we consider reasonable under
the circumstances. The unaudited consolidated condensed pro forma data is not
necessarily indicative of our future results of operations or the results of
operations as they might have been had the acquisitions and the related
financings, including our recent debt and equity offerings and the use of the
net proceeds from these offerings, been effective on the first day of the period
presented. The unaudited consolidated condensed pro forma financial data should
be read in conjunction with our separate historical consolidated financial
statements and notes included in this prospectus, the separate historical
consolidated financial statements and notes of ValueRx included in our Current
Report on Form 8-K/A dated June 12, 1998, the separate unaudited combined
condensed financial statements and notes for ValueRx for the three months ended
March 31, 1998 included in this prospectus and the separate historical financial
statements and notes of DPS included in our Current Report on Form 8-K/A dated
June 14, 1999.

     When reading the historical consolidated financial statements of us and
DPS, a notable difference exists with respect to the revenue recognition for
each of the companies. A substantial portion of our net revenues include
administrative fees, dispensing fees and the drug ingredient costs, as most
clients use one of our pharmacy networks. Where we only administer the contracts
between our clients and our clients' retail pharmacy networks, we record as net
revenues only the administrative fees we receive from our activities. DPS's net
revenues include its administrative fee from the activity of processing the
claim irrespective of a member utilizing a retail pharmacy included in one of
DPS's networks or its clients' network. The fundamental difference in the
revenue recognition is that DPS does not include the associated drug ingredient
costs in its net revenues as it does not have any liability to reimburse the
retail pharmacy included in its network unless DPS receives payment from its
client.

- -------------------------

 (1) Cost of revenues and selling, general and administrative expense include
     $2,265 and $6,222 of depreciation and amortization, respectively, for us
     during the first quarter of 1999. The pro forma consolidated cost of
     revenues and selling, general and administrative expense include $2,265 and
     $16,232 of depreciation and amortization, respectively.

 (2) Net revenues for DPS include revenues from SmithKline Beecham. Subsequent
     to our acquisition of DPS, revenues are anticipated to be consistent with
     historical revenues as DPS's existing contract with SmithKline Beecham
     remains in place.

 (3) Adjustment reflects the elimination of management fees paid to United
     HealthCare of $10,401 which under the DPS purchase agreement is to be
     reimbursed to us by SmithKline Beecham.

 (4) Adjustment reflects the net decrease in the first quarter of 1999 of
     depreciation and amortization expense to $260 from $2,150 recorded by DPS
     resulting from the allocation of the purchase price to the assets acquired
     at their fair market value and to conform estimated and useful lives.
     Furniture, equipment and internal use software are being depreciated by us
     using the straight-line method over estimated useful lives of 5 to 8 years.

 (5) Adjustment reflects the net decrease in the first quarter of 1999 of
     amortization expense for goodwill and other intangible assets. DPS's
     goodwill and other intangible assets amortization expense of $10,730 has
     been reversed, and our goodwill and other intangible assets, consisting of
     customer contracts, amortization of $9,750 has been included. Goodwill is
     being amortized using the straight-line method over the

                                       22
<PAGE>   27

     estimated useful life of 30 years. We have preliminarily assigned an
     estimated fair value to other intangible assets and are amortizing them
     using the straight-line method over the estimated useful lives of 1 to 20
     years. We anticipate spending an estimated $10 million to $20 million in
     non-recurring costs during the first twelve months subsequent to our
     acquisition of DPS relating to the integration of DPS's operations. These
     non-recurring costs have not been reflected in the unaudited consolidated
     condensed pro forma statement of operations.

 (6) Adjustment reflects the elimination of DPS's $359 equity loss in its joint
     venture. SmithKline Beecham retained the equity interest in the joint
     venture.

 (7) Adjustment reflects the decrease in interest income resulting from
     expending $48,081 of cash to consummate the acquisition of DPS. The
     adjustment was calculated using a current interest rate of 4.5% earned by
     us on our cash balances.

 (8) Adjustment reflects the following:

      - the elimination of $5,508 in actual interest expense, exclusive of the
        impact of our hedge on variable rate interest, incurred during the first
        quarter of 1999 on $360,000 of debt outstanding under our $440,000
        credit facility, which has been replaced with the $1,050,000 credit
        facility

      - the addition of $21,677 in interest expense from borrowings of $890,000
        under the $1,050,000 credit facility and $150,000 under the senior
        subordinated bridge credit facility, assuming interest rates on the
        $1,050,000 credit facility of 7.67% for the revolving facility and the
        Term A facility and 8.42% for the Term B facility, and a rate of 9.97%
        on the senior subordinated bridge credit facility, based on the actual
        rates incurred by us at consummation of the $1,050,000 credit facility
        and $150,000 senior subordinated bridge facility

      - the addition of $921 in deferred financing fees amortization and $44 in
        annual administrative fees; these deferred financing fees are being
        amortized using the straight-line method over 6 to 8 years, which
        represents the maturity of the term loans under the $1,050,000 credit
        facility

 (9) Adjustment reflects the tax effect of the pro forma adjustments at the
     combined federal and state statutory rate of 40%.

(10) Adjustment reflects the following:

      - the elimination of the interest expense impact of $6,436 from the
        retirement of the $150,000 senior subordinated bridge credit facility,
        at an interest rate in effect at consummation of 9.97%, and the
        retirement of $414,770 of the term loan borrowings under the $1,050,000
        credit facility, at the actual interest rate at consummation of 8.42%,
        using the net proceeds from our sale of 5,175 shares of Class A common
        stock, including the underwriters' over-allotments, offered pursuant to
        our equity offering, the net proceeds of our senior notes offering at an
        interest rate of 9.625% on the senior notes and the use of $25 million
        of our cash.

      - the elimination of the deferred financing fees amortization expense of
        $234 associated with the retirement of the term loan borrowings under
        our $1,050,000 credit facility

      - the addition of the amortization of $145 from the $5,813 in senior note
        deferred financing fees

(11) Adjustment reflects the tax effect of the interest expense adjustment at
     the combined federal and state statutory 40% tax rate.

(12) Adjustment reflects the addition for the full period of the 5,175 shares of
     Class A common stock, including the underwriters' over-allotments, in our
     equity offering at an offering price of $61 per share.

(13) EBITDA is earnings before interest, taxes, depreciation and amortization,
     or operating income plus depreciation and amortization. EBITDA is presented
     because it is a widely accepted indicator of a company's ability to incur
     and service indebtedness. EBITDA, however, should not be considered as an
     alternative to net income as a measure of operating performance or an
     alternative to cash flow as a measure of liquidity. In addition, our
     definition of EBITDA may not be comparable to that reported by other
     companies.

- -------------------------

 (1) These historical amounts represent the unaudited statement of operations of
     ValueRx from January 1, 1998 through March 31, 1998.

 (2) Cost of revenues and selling, general and administrative expense include
     $1,413 and $983 of depreciation and amortization, respectively, for us
     during the first quarter of 1998. The pro forma consolidated cost of
     revenues and selling, general and administrative expense include $1,413 and
     $16,198 of depreciation and amortization, respectively.

 (3) Adjustment reflects the net decrease in depreciation and amortization of
     property and equipment and intangible assets, including goodwill resulting
     from our allocation of the ValueRx purchase price and conforming estimated
     useful lives. ValueRx depreciation and amortization expense of $8,811 has
     been eliminated and $5,205 has been added based on the fair value of
     property and equipment, goodwill, and

                                       24
<PAGE>   29

     other intangible assets. The fair value of property and equipment ($33,756)
     is being depreciated using the straight-line method over 3 to 20 years.
     Goodwill ($289,863) and other intangible assets, consisting of non-compete
     agreements ($9,130) and customer contracts ($48,523), are being amortized
     using the straight-line method over 30 years and 2 to 20 years,
     respectively.

 (4) Adjustment reflects the decrease in interest income resulting from our
     expending $100,908 of our short-term investments and cash equivalents to
     consummate the acquisition of ValueRx. The adjustment was calculated using
     the average interest rate (5.0%) earned by us on our investments during the
     quarter prior to the ValueRx acquisition.

 (5) Adjustment records the additional net interest expense and the amortization
     of the deferred financing fees during the first quarter of 1998 associated
     with the $440,000 credit facility utilized for the acquisition of ValueRx.
     The additional interest expense was determined assuming an average
     borrowing rate of 7.13% on the $360,000 borrowed under the $440,000 credit
     facility incurred to consummate the acquisition.

 (6) Adjustment reflects the tax effect of the pro forma adjustments at the
     combined federal and state statutory rate of 40%.

 (7) Net revenues for DPS include revenues from SmithKline Beecham. Subsequent
     to our acquisition of DPS, revenues are anticipated to be consistent with
     historical revenues as DPS's existing contract with SmithKline Beecham
     remains in place.

 (8) Adjustment reflects the elimination of management fees paid to United
     HealthCare of $7,675, which under the DPS purchase agreement is to be
     reimbursed to us by SmithKline Beecham.

 (9) Adjustment reflects the net decrease in the 1998 depreciation and
     amortization expense to $260 from $1,288 recorded by DPS resulting from the
     allocation of the purchase price to the assets acquired at their fair
     market value and to conform estimated and useful lives. Furniture,
     equipment and internal use software are being depreciated by us using the
     straight-line method over estimated useful lives of 5 to 8 years.

(10) Adjustment reflects the net decrease in the 1998 amortization expense for
     goodwill and other intangible assets. DPS's goodwill and other intangible
     assets amortization expense of $18,439 has been reversed, and our goodwill
     and other intangible assets, consisting of customer contracts, amortization
     of $9,750 has been included. Goodwill is being amortized using the
     straight-line method over the estimated useful life of 30 years. We have
     preliminarily assigned an estimated fair value to other intangible assets
     and are amortizing them using the straight-line method over the estimated
     useful lives of 1 to 20 years. We anticipate spending an estimated $10
     million to $20 million in non-recurring costs during the first twelve
     months subsequent to our acquisition of DPS relating to the integration of
     DPS's operations. These non-recurring costs have not been reflected in the
     unaudited consolidated condensed pro forma statement of operations.

(11) Adjustment reflects the elimination of DPS's $431 equity loss in its joint
     venture. SmithKline Beecham retained the equity interest in the joint
     venture.

(12) Adjustment reflects the decrease in interest income for the first quarter
     of 1998 resulting from expending $48,081 of cash to consummate the
     acquisition of DPS. The adjustment was calculated using a current interest
     rate of 4.5% earned by us on our cash balances.

(13) Adjustment reflects the following:

      - the elimination of $7,007 in first quarter of 1998 interest expense
        relating to the ValueRx acquisition, exclusive of the impact of our
        hedge on variable rate interest, incurred during the first quarter of
        1998 on $360,000 of debt outstanding under our $440,000 credit facility,
        which has been replaced with the $1,050,000 credit facility

                                       25
<PAGE>   30

      - the addition of $21,677 in interest expense from borrowings of $890,000
        under the $1,050,000 credit facility and $150,000 under the senior
        subordinated bridge credit facility, assuming interest rates on the
        $1,050,000 credit facility of 7.67% for the revolving facility and the
        Term A facility and 8.42% for the Term B facility, and a rate of 9.97%
        on the senior subordinated bridge credit facility, based on the actual
        rates incurred by us at consummation of the $1,050,000 credit facility
        and $150,000 senior subordinated bridge credit facility

      - the addition of $921 in deferred financing fees amortization and $44 in
        annual administrative fees; these deferred financing fees are being
        amortized using the straight-line method over 6 to 8 years, which
        represents the maturity of the term loans under the $1,050,000 credit
        facility

(14) Adjustment reflects the tax effect of the pro forma adjustments at the
     combined federal and state statutory rate of 40%.

(15) Adjustment reflects the following:

     - the elimination of the interest expense impact of $6,436 from the
       retirement of the $150,000 senior subordinated bridge credit facility, at
       an interest rate in effect at consummation of 9.97%, and the retirement
       of $414,770 of the term loan borrowings under the $1,050,000 credit
       facility, at the actual interest rate at consummation of 8.42%, using the
       net proceeds from our sale of 5,175 shares of Class A common stock,
       including the underwriters' over-allotments, offered pursuant to our
       equity offering, the net proceeds of our senior notes offering at an
       interest rate of 9.625% on the senior notes and the use of $25 million of
       our cash

     - the elimination of the deferred financing fees amortization expense of
       $234 associated with the retirement of the term loan borrowings under our
       $1,050,000 credit facility

     - the addition of the amortization of $145 from the $5,813 in senior note
       deferred financing fees

(16) Adjustment reflects the tax effect of the interest expense adjustment at
     the combined federal and state statutory 40% tax rate.

(17) Adjustment reflects the addition for the full period of the 5,175 shares of
     Class A common stock, including the underwriters' over-allotments, in our
     equity offering at an offering price of $61 per share.

(18) EBITDA is earnings before interest, taxes, depreciation and amortization,
     or operating income plus depreciation and amortization. EBITDA is presented
     because it is a widely accepted indicator of a company's ability to incur
     and service indebtedness. EBITDA, however, should not be considered as an
     alternative to net income as a measure of operating performance or an
     alternative to cash flow as a measure of liquidity. In addition, our
     definition of EBITDA may not be comparable to that reported by other
     companies.

- -------------------------

 (1) These historical amounts represent the unaudited statement of operations of
     ValueRx from January 1, 1998 through March 31, 1998.

 (2) Cost of revenues and selling, general and administrative expense include
     $7,559 and $18,874 of depreciation and amortization, respectively, for us
     in 1998. The pro forma consolidated cost of revenues and selling, general
     and administrative expense include $7,559 and $67,709 of depreciation and
     amortization, respectively.

                                       27
<PAGE>   32

 (3) Adjustment reflects the net decrease in depreciation and amortization of
     property and equipment and intangible assets, including goodwill resulting
     from our allocation of the ValueRx purchase price and conforming estimated
     useful lives. ValueRx depreciation and amortization expense of $8,811 has
     been eliminated and $5,205 has been added based on the fair value of
     property and equipment, goodwill, and other intangible assets. The fair
     value of property and equipment ($33,756) is being depreciated using the
     straight-line method over 3 to 20 years. Goodwill ($289,863) and other
     intangible assets, consisting of non-compete agreements ($9,130) and
     customer contracts ($48,523), are being amortized using the straight-line
     method over 30 years and 2 to 20 years, respectively.

 (4) Adjustment reflects the decrease in interest income resulting from our
     expending $100,908 of our short-term investments and cash equivalents to
     consummate the acquisition of ValueRx. The adjustment was calculated using
     the average interest rate (5.0%) earned by us on our investments during the
     quarter prior to the ValueRx acquisition.

 (5) Adjustment records the additional net interest expense and the amortization
     of the deferred financing fees during the first quarter of 1998 associated
     with the $440,000 credit facility utilized for the acquisition of ValueRx.
     The additional interest expense was determined assuming an average
     borrowing rate of 7.13% on the $360,000 borrowed under the $440,000 credit
     facility incurred to consummate the acquisition.

 (6) Adjustment reflects the tax effect of the pro forma adjustments at the
     combined federal and state statutory rate of 40%.

 (7) Net revenues for DPS include revenues from SmithKline Beecham. Subsequent
     to our acquisition of DPS, revenues are anticipated to be consistent with
     historical revenues as DPS's existing contract with SmithKline Beecham
     remains in place.

 (8) Adjustment reflects the elimination of management fees paid to United
     HealthCare of $33,837, which under the DPS purchase agreement is to be
     reimbursed to us by SmithKline Beecham.

 (9) Adjustment reflects the net decrease in the 1998 depreciation and
     amortization expense to $4,695 from $6,383 recorded by DPS resulting from
     the allocation of the purchase price to the assets acquired at their fair
     market value and to conform estimated and useful lives. Furniture,
     equipment and internal use software are being depreciated by us using the
     straight-line method over estimated useful lives of 5 to 8 years.

(10) Adjustment reflects the net decrease in the 1998 amortization expense for
     goodwill and other intangible assets. DPS's goodwill and other intangible
     assets amortization expense of $73,758 has been reversed, and our goodwill
     and other intangible assets, consisting of customer contracts, amortization
     of $38,935 has been included. Goodwill is being amortized using the
     straight-line method over the estimated useful life of 30 years. We have
     preliminarily assigned an estimated fair value to other intangible assets
     and are amortizing them using the straight-line method over the estimated
     useful lives of 1 to 20 years. We anticipate spending an estimated $10
     million to $20 million in non-recurring costs during the first twelve
     months subsequent to our acquisition of DPS relating to the integration of
     DPS's operations. These non-recurring costs have not been reflected in the
     unaudited consolidated condensed pro forma statement of operations.

(11) Adjustment reflects the elimination of DPS's $1,924 equity loss in its
     joint venture. SmithKline Beecham retained the equity interest in the joint
     venture.

(12) Adjustment reflects the decrease in interest income resulting from
     expending $48,081 of cash to consummate the acquisition of DPS. The
     adjustment was calculated using a current interest rate of 4.5% earned by
     us on our cash balances.

                                       28
<PAGE>   33

(13) Adjustment reflects the following:

      - the elimination of $26,413 in actual interest expense, exclusive of the
        impact of our hedge on variable rate interest, incurred during fiscal
        1998 on $360,000 of debt outstanding under our $440,000 credit facility,
        which has been replaced with the $1,050,000 credit facility

      - the addition of $87,832 in interest expense from borrowings of $890,000
        under the $1,050,000 credit facility and $150,000 under the senior
        subordinated bridge credit facility, assuming interest rates on the
        $1,050,000 credit facility of 7.67% for the revolving facility and the
        Term A facility and 8.42% for the Term B facility, and an average rate
        of 10.72% on the senior subordinated bridge credit facility, based on
        the actual rates incurred by us at consummation of the $1,050,000 credit
        facility and $150,000 senior subordinated bridge facility. The interest
        rate on the senior subordinated bridge facility loan increases 0.5%
        every quarter starting at 9.97% and increasing to 11.47%

      - the addition of $3,688 in deferred financing fees amortization and $175
        in annual administrative fees; these deferred financing fees are being
        amortized using the straight-line method over 6 to 8 years, which
        represents the maturity of the term loans under the $1,050,000 credit
        facility

(14) Adjustment reflects the tax effect of the pro forma adjustments at the
     combined federal and state statutory rate of 40%.

(15) Adjustment reflects the following:

      - the elimination of the interest expense impact of $26,871 from the
        retirement of the $150,000 senior subordinated bridge credit facility,
        at an interest rate in effect at consummation of 9.97%, and the
        retirement of $414,770 of the term loan borrowings under the $1,050,000
        credit facility, at the actual interest rate at consummation of 8.42%,
        using the net proceeds from our sale of 5,175 shares of Class A common
        stock, including the underwriters' over-allotments, offered pursuant to
        our equity offering, the net proceeds of our senior notes offering at an
        interest rate of 9.625% on the senior notes and the use of $25 million
        of our cash

      - the elimination of the deferred financing fees amortization expense of
        $936 associated with the retirement of the term loan borrowings under
        our $1,050,000 credit facility

      - the addition of the amortization of $581 from the $5,813 in senior note
        deferred financing fees

(16) Adjustment reflects the tax effect of the interest expense adjustment at
     the combined federal and state statutory 40% tax rate.

(17) The write-down of assets on DPS's books of $1,092,184 relates to the
     impairment of goodwill. If the acquisition of DPS had occurred on January
     1, 1998, goodwill on DPS's books would have been eliminated. Therefore, the
     impairment charge for goodwill would not have existed. Net income excluding
     this impairment charge would have been $50,198, or $1.31 per basic share
     and $1.29 per diluted share.

(18) Adjustment reflects the addition for a full year of our offering of 5,175
     shares of Class A common stock, including the underwriters'
     over-allotments, in our equity offering at an offering price of $61 per
     share.

(19) EBITDA is earnings before interest, taxes, depreciation and amortization,
     or operating income plus depreciation and amortization. EBITDA is presented
     because it is a widely accepted indicator of a company's ability to incur
     and service indebtedness. EBITDA, however, should not be considered as an
     alternative to net income as a measure of operating performance or an
     alternative to cash flow as a measure of liquidity. In addition, our
     definition of EBITDA may not be comparable to that reported by other
     companies.

- -------------------------
 (1) Adjustment reflects the use of $48,081 of our cash balances to fund the
     purchase of DPS.

 (2) Adjustment reflects the elimination of the historical deferred tax assets
     of DPS. As part of its acquisition, we will file an Internal Revenue Code
     sec. 338(h)(10) election. Accordingly, at March 31, 1999, the tax basis
     balance sheet and the book basis balance sheet are estimated to be the
     same, and therefore no deferred taxes are recognized with respect to DPS.

 (3) Adjustment reflects the fair value assigned to DPS property and equipment.

 (4) Adjustment reflects the excess of the purchase price of DPS over the
     estimated fair market value of the identified assets acquired. The purchase
     price of $700 million, plus an estimated $25 million in

                                       30

     transaction costs, plus the assumption and incurrence of liabilities
     totalling $284,325 was preliminarily allocated in the following manner:

Goodwill....................................................   727,332
Liabilities.................................................   284,325
</TABLE>

     We anticipate assessing the value of all long-lived assets acquired when
     events or 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.

 (5) Adjustment reflects the following:

     - elimination of the unamortized deferred financing fees in the amount of
       $3,250 related to the extinguishment of our $440,000 credit facility

     - elimination of other intangible assets of DPS in the amount of $279,583

     These eliminations were offset by $19,483 paid in deferred financing fees
     related to the $1,050,000 credit facility used to finance the DPS
     acquisition and the preliminary allocation of fair value to customer
     contracts in the amount of $132,310. We are in the process of establishing
     fair values for all identifiable assets and will adjust the fair value
     allocated to customer contracts accordingly when complete.

 (6) Adjustment reflects borrowings of $890,000 under our $1,050,000 credit
     facility and $150,000 under the senior subordinated bridge credit facility
     to finance the acquisition of DPS and which refinanced our existing
     outstanding debt of $360,000 under our $440,000 credit facility. The
     $1,050,000 credit facility consists of a $300,000 revolving credit
     facility, of which $140,000 has been borrowed, and a $750,000 term
     facility.

 (7) Adjustment reflects the reduction of taxes payable by $1,300 for the
     write-off of deferred financing fees, and the payment of accrued interest
     of $5,063 associated with the repayment of the $440,000 credit facility.
     These amounts were offset by accruals of $1,982 for transaction costs and
     an estimated $16,000 for other liabilities associated with the purchase of
     DPS, such as facility consolidation and employee transition costs, that we
     are presently identifying and evaluating.

 (8) Adjustment reflects the elimination of the DPS pre-acquisition equity
     balances and the write-off of our unamortized deferred financing fees of
     approximately $1,950, net of tax, from our $440,000 credit facility as an
     extraordinary item. After the write-off of the unamortized deferred
     financing fees, net income after extraordinary items for the three months
     ended March 31, 1999 would have been $18,375, or $0.48 per basic share and
     $0.47 per diluted share.

 (9) Adjustment reflects the elimination of our unamortized deferred financing
     fees related to the extinguishment of $414,770 borrowed under the
     $1,050,000 credit facility and the $150,000 senior subordinated bridge
     credit facility offset by $5,813 in deferred financing fees for this
     offering.

(10) Adjustment reflects the reduction in taxes payable as a result of the
     write-off of deferred financing fees related to the extinguishment of
     $414,770 borrowed under our $1,050,000 credit facility.


(11) Adjustment reflects the net proceeds received from our sale of 5,175 shares
     of Class A common stock, including the underwriters' over-allotments, at an
     offering price of $61 per share and from our senior notes offering. The
     proceeds from our equity offering and our senior notes offering, along with
     approximately $25 million of our cash, will be used to repay the $150,000
     senior subordinated bridge credit facility and $414,770 of the term loans
     under the $1,050,000 credit facility. The proceeds are offset by the
     write-off of approximately $4,495, net of tax, of the deferred financing
     fees from the $1,050,000 credit facility as an extraordinary item. After
     the write-off of $4,495 and $1,950, see (7) above, in unamortized deferred
     financing fees, net income after extraordinary items for the three months
     ended March 31, 1999 would have been $13,880, or $0.36 per basic share and
     $0.35 per diluted share. In July 1999, we repaid an additional $50,230 of
     the term loans through use of our own cash. As a result, we will record an
     additional extraordinary charge of approximately $557, net of tax, for the
     write-off of deferred financing fees.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     We have entered into a registration rights agreement with the initial
purchasers of the outstanding notes in which we agreed, under certain
circumstances, to file a registration statement relating to an offer to exchange
the outstanding notes for exchange notes. We also agreed to use our reasonable
best efforts to cause such offer to be consummated no later than 220 days after
the original issue of the outstanding notes. The exchange notes will have terms
substantially identical to the outstanding notes except that the exchange notes
will not contain terms with respect to transfer restrictions, registration
rights and liquidated damages for failure to observe certain obligations in the
registration rights agreement. The outstanding notes were issued on June 16,
1999.

     Under the circumstances set forth below, we will use our reasonable best
efforts to cause the SEC to declare effective a shelf registration statement
with respect to the resale of the outstanding notes and keep the statement
effective for up to two years after the effective date of the shelf registration
statement. These circumstances include:

     - if any changes in law, SEC rules or regulations or applicable
       interpretations thereof by the staff of the SEC do not permit us to
       effect the exchange offer as contemplated by the registration rights
       agreement

     - if any outstanding notes validly tendered in the exchange offer are not
       exchanged for exchange notes no later than 220 days after the original
       issue of the outstanding notes

     - if any initial purchaser of the outstanding notes so requests (but only
       with respect to any outstanding notes not eligible to be exchanged for
       exchange notes in the exchange offer)

     - if any holder of the outstanding notes notifies us that it is not
       permitted to participate in the exchange offer or would not receive fully
       tradable exchange notes pursuant to the exchange offer

     If we fail to comply with certain obligations under the registration rights
agreement, we will be required to pay liquidated damages to holders of the
outstanding notes. Please read "Description of the Notes -- Registered Exchange
Offer; Registration Rights" for more details regarding the registration rights
agreement.

     Each holder of outstanding notes that wishes to exchange such outstanding
notes for transferable exchange notes in the exchange offer will be required to
make the following representations:

     - any exchange notes will be acquired in the ordinary course of its
       business

     - such holder has no arrangement with any person to participate in the
       distribution of the exchange notes

     - such holder is not an "affiliate," as defined in Rule 405 of the
       Securities Act, of Express Scripts or if it is an affiliate, that it will
       comply with applicable registration and prospectus delivery requirements
       of the Securities Act

     Each broker-dealer that receives exchange notes for its own account in
exchange for outstanding notes, where such outstanding notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such exchange notes. See "Plan of Distribution."

<PAGE>   37

RESALE OF EXCHANGE NOTES

     Based on interpretations of the SEC staff set forth in no action letters
issued to unrelated third parties, we believe that exchange notes issued under
the exchange offer in exchange for outstanding notes may be offered for resale,
resold and otherwise transferred by any exchange note holder without compliance
with the registration and prospectus delivery provisions of the Securities Act,
if:

     - such holder is not an "affiliate" of Express Scripts within the meaning
       of Rule 405 under the Securities Act

     - such exchange notes are acquired in the ordinary course of the holder's
       business

     - the holder does not intend to participate in the distribution of such
       exchange notes

     Any holder who tenders in the exchange offer with the intention of
participating in any manner in a distribution of the exchange notes:

     - cannot rely on the position of the staff of the SEC enunciated in Exxon
       Capital Holdings Corporation or similar interpretive letters

     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with a secondary resale transaction

     This prospectus may be used for an offer to resell, resale or other
retransfer of exchange notes only as specifically set forth in this prospectus.
With regard to broker-dealers, only broker-dealers that acquired the outstanding
notes as a result of market-making activities or other trading activities may
participate in the exchange offer. Each broker-dealer that receives exchange
notes for its own account in exchange for outstanding notes, where such
outstanding notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of the exchange notes.
Please read "Plan of Distribution" for more details regarding the transfer of
exchange notes.

TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, we will accept for exchange any outstanding
notes properly tendered and not withdrawn prior to the expiration date. We will
issue $1,000 principal amount of exchange notes in exchange for each $1,000
principal amount of outstanding notes surrendered under the exchange offer.
Outstanding notes may be tendered only in integral multiples of $1,000.

     The form and terms of the exchange notes will be substantially identical to
the form and terms of the outstanding notes except the exchange notes will be
registered under the Securities Act, will not bear legends restricting their
transfer and will not provide for any liquidated damages upon our failure to
fulfill our obligations under the registration rights agreement to file, and
cause to be effective, a registration statement. The exchange notes will
evidence the same debt as the outstanding notes. The exchange notes will be
issued under and entitled to the benefits of the same indenture that authorized
the issuance of the outstanding notes. Consequently, both series will be treated
as a single class of debt securities under that indenture. For a description of
the indenture, see "Description of the Notes."

     The exchange offer is not conditioned upon any minimum aggregate principal
amount of outstanding notes being tendered for exchange.

     As of the date of this prospectus, $250 million aggregate principal amount
of the outstanding notes are outstanding. This prospectus and the letter of
transmittal are being

                                       33
<PAGE>   38

sent to all registered holders of outstanding notes. There will be no fixed
record date for determining registered holders of outstanding notes entitled to
participate in the exchange offer.

     We intend to conduct the exchange offer in accordance with the provisions
of the registration rights agreement, the applicable requirements of the
Securities Act and the Exchange Act and the rules and regulations of the SEC.
Outstanding notes that are not tendered for exchange in the exchange offer will
remain outstanding and continue to accrue interest and will be entitled to the
rights and benefits such holders have under the indenture relating to the
outstanding notes and the registration rights agreement.

     We will be deemed to have accepted for exchange properly tendered
outstanding notes when we have given oral or written notice of the acceptance to
the exchange agent. The exchange agent will act as agent for the tendering
holders for the purposes of receiving the exchange notes from us and delivering
exchange notes to such holders. Subject to the terms of the registration rights
agreement, we expressly reserve the right to amend or terminate the exchange
offer, and not to accept for exchange any outstanding notes not previously
accepted for exchange, upon the occurrence of any of the conditions specified
below under "--Certain Conditions to the Exchange Offer."

     Holders who tender outstanding notes in the exchange offer will not be
required to pay brokerage commissions or fees or, subject to the instructions in
the letter of transmittal, transfer taxes with respect to the exchange of
outstanding notes. We will pay all charges and expenses, other than certain
applicable taxes described below, in connection with the exchange offer. It is
important that you read "--Fees and Expenses" below for more details regarding
fees and expenses incurred in the exchange offer.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS


     The exchange offer will expire at 5:00 p.m., New York City time on
September 8, 1999, unless in our sole discretion, we extend it.


     In order to extend the exchange offer, we will notify the exchange agent
orally or in writing of any extension. We will notify the registered holders of
outstanding notes of the extension no later than 9:00 a.m., New York City time,
on the business day after the previously scheduled expiration date.

     We reserve the right, in our sole discretion:

     - to delay accepting for exchange any outstanding notes

     - to extend the exchange offer or to terminate the exchange offer and to
       refuse to accept outstanding notes not previously accepted if any of the
       conditions set forth below under "--Certain Conditions to the Exchange
       Offer" have not been satisfied, by giving oral or written notice of such
       delay, extension or termination to the exchange agent

     - subject to the terms of the registration rights agreement, to amend the
       terms of the exchange offer in any manner

     Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof to the
registered holders of outstanding notes. If we amend the exchange offer in a
manner that we determine to constitute a material change, we will promptly
disclose such amendment in a manner reasonably calculated to inform the holders
of outstanding notes of such amendment.

     Without limiting the manner in which we may choose to make public
announcements of any delay in acceptance, extension, termination or amendment of
the exchange offer, we

                                       34
<PAGE>   39

shall have no obligation to publish, advertise, or otherwise communicate any
such public announcement, other than by making a timely release to a financial
news service.

CERTAIN CONDITIONS TO THE EXCHANGE OFFER

     Despite any other term of the exchange offer, we will not be required to
accept for exchange, or exchange any exchange notes for, any outstanding notes,
and we may terminate the exchange offer as provided in this prospectus before
accepting any outstanding notes for exchange if in our reasonable judgment:

     - the exchange notes to be received will not be tradeable by the holder,
       without restriction under the Securities Act or the Exchange Act and
       without material restrictions under the blue sky or securities laws of
       substantially all of the states of the United States

     - the exchange offer, or the making of any exchange by a holder of
       outstanding notes, would violate applicable law or any applicable
       interpretation of the staff of the SEC

     - any action or proceeding has been instituted or threatened in any court
       or by or before any governmental agency with respect to the exchange
       offer that, in our judgment, would reasonably be expected to impair our
       ability to proceed with the exchange offer

     In addition, we will not be obligated to accept for exchange the
outstanding notes of any holder that has not made to us

     - the representations described under "--Purpose and Effect of the Exchange
       Offer," "--Procedures for Tendering" and "Plan of Distribution"

     - such other representations as may be reasonably necessary under
       applicable SEC rules, regulations or interpretations to make available to
       us an appropriate form for registration of the exchange notes under the
       Securities Act

     We expressly reserve the right, at any time or at various times, to extend
the period of time during which the exchange offer is open. Consequently, we may
delay acceptance of any outstanding notes by giving oral or written notice of
such extension to their holders. During any such extensions, all outstanding
notes previously tendered will remain subject to the exchange offer, and we may
accept them for exchange. We will return any outstanding notes that we do not
accept for exchange for any reason without expense to their tendering holder as
promptly as practicable after the expiration or termination of the exchange
offer.

     We expressly reserve the right to amend or terminate the exchange offer,
and to reject for exchange any outstanding notes not previously accepted for
exchange, upon the occurrence of any of the conditions of the exchange offer
specified above. We will give oral or written notice of any extension,
amendment, non-acceptance or termination to the holders of the outstanding notes
as promptly as practicable. In the case of any extension, such notice will be
issued no later than 9:00 a.m., New York City time, on the business day after
the previously scheduled expiration date.

     These conditions are for our sole benefit and we may assert them regardless
of the circumstances that may give rise to them or waive them in whole or in
part at any or at various times in our sole discretion. If we fail at any time
to exercise any of the foregoing rights, this failure will not constitute a
waiver of such right. Each such right will be deemed an ongoing right that we
may assert at any time or at various times.

     In addition, we will not accept for exchange any outstanding notes
tendered, and will not issue exchange notes in exchange for any such outstanding
notes, if at such time any

                                       35
<PAGE>   40

stop order will be threatened or in effect with respect to the registration
statement of which this prospectus constitutes a part or the qualification of
the indenture under the Trust Indenture Act of 1939.

PROCEDURES FOR TENDERING

     Only a holder of outstanding notes may tender such outstanding notes in the
exchange offer. To tender in the exchange offer, a holder must:

     - complete, sign and date the letter of transmittal, or a facsimile of the
       letter of transmittal; have the signature on the letter of transmittal
       guaranteed if the letter of transmittal so requires; and mail or deliver
       such letter of transmittal or facsimile to the exchange agent prior to
       the expiration date or

     - comply with DTC's Automated Tender Offer Program procedures described
       below

     In addition, either:

     - the exchange agent must receive outstanding notes along with the letter
       of transmittal or

     - the exchange agent must receive, prior to the expiration date, a timely
       confirmation of book-entry transfer of such outstanding notes into the
       exchange agent's account at DTC according to the procedure for book-entry
       transfer described below or a properly transmitted agent's message or

     - the holder must comply with the guaranteed delivery procedures described
       below

     To be tendered effectively, the exchange agent must receive any physical
delivery of the letter of transmittal and other required documents at the
address set forth below under "--Exchange Agent" prior to the expiration date.

     The tender by a holder that is not withdrawn prior to the expiration date
will constitute an agreement between such holder and us in accordance with the
terms and subject to the conditions set forth in this prospectus and in the
letter of transmittal.

     The method of delivery of outstanding notes, the letter of transmittal and
all other required documents to the exchange agent is at the holder's election
and risk. Rather than mail these items, we recommend that holders use an
overnight or hand delivery service. In all cases, holders should allow
sufficient time to assure delivery to the exchange agent before the expiration
date. Holders should not send the letter of transmittal or outstanding notes to
us. Holders may request their respective brokers, dealers, commercial banks,
trust companies or other nominees to effect the above transactions for them.

     Any beneficial owner whose outstanding notes are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct it to
tender on the owner's behalf. If such beneficial owner wishes to tender on its
own behalf, it must, prior to completing and executing the letter of transmittal
and delivering its outstanding notes either:

     - make appropriate arrangements to register ownership of the outstanding
       notes in such owner's name or

     - obtain a properly completed bond power from the registered holder of
       outstanding notes

     The transfer of registered ownership may take considerable time and may not
be completed prior to the expiration date.

     Signatures on a letter of transmittal or a notice of withdrawal described
below must be guaranteed by a member firm of a registered national securities
exchange or of the

                                       36
<PAGE>   41

National Association of Securities Dealers, Inc., a commercial bank or trust
company having an office or correspondent in the United States or another
"eligible institution" within the meaning of Rule 17Ad-15 under the Exchange
Act, unless the outstanding notes tendered pursuant thereto are tendered:

     - by a registered holder who has not competed the box entitled "Special
       Issuance Instructions" or "Special Delivery Instructions" on the letter
       of transmittal or

     - for the account of an eligible institution

     If the letter of transmittal is signed by a person other than the
registered holder of any outstanding notes listed on the outstanding notes, such
outstanding notes must be endorsed or accompanied by a properly completed bond
power. The bond power must be signed by the registered holder as the registered
holder's name appears on the outstanding notes and an eligible institution must
guarantee the signature on the bond power.

     If the letter of transmittal or any outstanding notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing. Unless waived by us,
they should also submit evidence satisfactory to us of their authority to
deliver the letter of transmittal.

     The exchange agent and DTC have confirmed that any financial institution
that is a participant in DTC's system may use DTC's Automated Tender Offer
Program to tender. Participants in the program may, instead of physically
completing and signing the letter of transmittal and delivering it to the
exchange agent, transmit their acceptance of the exchange offer electronically.
They may do so by causing DTC to transfer the outstanding notes to the exchange
agent in accordance with its procedures for transfer. DTC will then send an
agent's message to the exchange agent. The term "agent's message" means a
message transmitted by DTC, received by the exchange agent and forming part of
the book-entry confirmation, to the effect that:

     - DTC has received an express acknowledgment from a participant in its
       Automated Tender Offer Program that is tendering outstanding notes that
       are the subject of such book-entry confirmation

     - such participant has received and agrees to be bound by the terms of the
       letter of transmittal (or, in the case of an agent's message relating to
       guaranteed delivery, that such participant has received and agrees to be
       bound by the applicable notice of guaranteed delivery)

     - the agreement may be enforced against such participant

     We will determine in our sole discretion all questions as to the validity,
form, eligibility (including time of receipt), acceptance of tendered
outstanding notes and withdrawal of tendered outstanding notes. Our
determination will be final and binding. We reserve the absolute right to reject
any outstanding notes not properly tendered or any outstanding notes the
acceptance of which would, in the opinion of our counsel, be unlawful. We also
reserve the right to waive any defects, irregularities or conditions of tender
as to particular outstanding notes. Our interpretation of the terms and
conditions of the exchange offer (including the instructions in the letter of
transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of outstanding notes must
be cured within such time as we shall determine. Although we intend to notify
holders of defects or irregularities with respect to tenders of outstanding
notes, neither Express Scripts, the exchange agent nor any other person will
incur any liability for failure to give such notification. Tenders of
outstanding notes will not

                                       37
<PAGE>   42

be deemed made until such defects or irregularities have been cured or waived.
Any outstanding notes received by the exchange agent that are not properly
tendered and as to which the defects or irregularities have not been cured or
waived will be returned to the exchange agent without cost to the tendering
holder, unless otherwise provided in the letter of transmittal, as soon as
practicable following the expiration date.

     In all cases, we will issue exchange notes for outstanding notes that we
have accepted for exchange under the exchange offer only after the exchange
agent timely receives:

     - outstanding notes or a timely book-entry confirmation of such outstanding
       notes into the exchange agent's account at DTC

     - a properly completed and duly executed letter of transmittal and all
       other required documents or a properly transmitted agent's message

     By signing the letter of transmittal, each tendering holder of outstanding
notes will represent to us that, among other things:

     - any exchange notes that the holder receives will be acquired in the
       ordinary course of its business

     - the holder has no arrangement or understanding with any person or entity
       to participate in the distribution of the exchange notes

     - if the holder is not a broker-dealer, that it is not engaged in and does
       not intend to engage in the distribution of the exchange notes

     - if the holder is a broker-dealer that will receive exchange notes for its
       own account in exchange for outstanding notes that were acquired as a
       result of market-making activities, that it will deliver a prospectus, as
       required by law, in connection with any resale of such exchange notes

     - the holder is not an "affiliate," as defined in Rule 405 of the
       Securities Act, of Express Scripts or, if the holder is an affiliate, it
       will comply with any applicable registration and prospectus delivery
       requirements of the Securities Act

     Each broker-dealer that receives exchange notes for its own account in
exchange for outstanding notes, where such outstanding notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such exchange notes. See "Plan of Distribution."

BOOK-ENTRY TRANSFER

     The exchange agent will make a request to establish an account with respect
to the outstanding notes at DTC for purposes of the exchange offer promptly
after the date of this prospectus; and any financial institution participating
in DTC's system may make book-entry delivery of outstanding notes by causing DTC
to transfer such outstanding notes into the exchange agent's account at DTC in
accordance with DTC's procedures for transfer. Holders of outstanding notes who
are unable to deliver confirmation of the book-entry tender of their outstanding
notes into the exchange agent's account at DTC or all other documents required
by the letter of transmittal to the exchange agent on or prior to the expiration
date must tender their outstanding notes according to the guaranteed delivery
procedures described below.

GUARANTEED DELIVERY PROCEDURES

     Holders wishing to tender their outstanding notes but whose outstanding
notes are not immediately available or who cannot deliver their outstanding
notes, the letter of

                                       38
<PAGE>   43

transmittal or any other required documents to the exchange agent or comply with
the applicable procedures under DTC's Automated Tender Offer Program prior to
the expiration date may tender if:

     - the tender is made through an eligible institution

     - prior to the expiration date, the exchange agent receives from such
       eligible institution either a properly completed and duly executed notice
       of guaranteed delivery (by facsimile transmission, mail or hand delivery)
       or a properly transmitted agent's message and notice of guaranteed
       delivery:

        - setting forth the name and address of the holder, the registered
          number(s) of such outstanding notes and the principal amount of
          outstanding notes tendered

        - stating that the tender is being made thereby

        - guaranteeing that, within three (3) New York Stock Exchange trading
          days after the expiration date, the letter of transmittal (or
          facsimile thereof) together with the outstanding notes or a book-entry
          confirmation, and any other documents required by the letter of
          transmittal, will be deposited by the eligible institution with the
          exchange agent

     - the exchange agent receives such properly completed and executed letter
       of transmittal (or facsimile thereof), as well as all tendered
       outstanding notes in proper form for transfer or a book-entry
       confirmation, and all other documents required by the letter of
       transmittal, within three (3) New York State Exchange trading days after
       the expiration date

WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, holders of outstanding
notes may withdraw their tenders at any time prior to the expiration date.

     For a withdrawal to be effective:

     - the exchange agent must receive a written notice (which may be by
       telegram, telex, facsimile transmission or letter) of withdrawal at one
       of the addresses set forth below under "--Exchange Agent" or

     - holders must comply with the appropriate procedures of DTC's Automated
       Tender Offer Program system

     Any such notice of withdrawal must:

     - specify the name of the person who tendered the outstanding notes to be
       withdrawn

     - identify the outstanding notes to be withdrawn (including the principal
       amount of such outstanding notes)

     - where certificates for outstanding notes have been transmitted, specify
       the name in which such outstanding notes were registered, if different
       from that of the withdrawing holder

     If certificates for outstanding notes have been delivered or otherwise
identified to the exchange agent, then, prior to the release of such
certificates, the withdrawing holder must also submit:

     - the serial numbers of the particular certificates to be withdrawn

     - a signed notice of withdrawal with signatures guaranteed by an eligible
       institution unless such holder is an eligible institution

                                       39
<PAGE>   44

     If outstanding notes have been tendered pursuant to the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at DTC to be credited with the withdrawn
outstanding notes and otherwise comply with the procedures of such facility. We
will determine all questions as to the validity, form and eligibility (including
time of receipt) of such notices, and our determination shall be final and
binding on all parties. We will deem any outstanding notes so withdrawn not to
have been validly tendered for exchange for purposes of the exchange offer. Any
outstanding notes that have been tendered for exchange but that are not
exchanged for any reason will be returned to their holder without cost to the
holder (or, in the case of outstanding notes tendered by book-entry transfer
into the exchange agent's account at DTC according to the procedures described
above, such outstanding notes will be credited to an account maintained with DTC
for outstanding notes) as soon as practicable after withdrawal, rejection of
tender or termination of the exchange offer. Properly withdrawn outstanding
notes may be retendered by following one of the procedures described under
"--Procedures for Tendering" above at any time on or prior to the expiration
date.

DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH
ABOVE OR TRANSMISSION VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT

FEES AND EXPENSES

     We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, we may make additional solicitation by
telegraph, telephone or in person by our officers and regular employees and
those of our affiliates.

     We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to broker-dealers or others soliciting
acceptances of the exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and reimburse it for its related
reasonable out-of-pocket expenses.

                                       40
<PAGE>   45


     We will pay the cash expenses to be incurred in connection with the
exchange offer. The expenses are estimated in the aggregate to be approximately
$230,000. They include:


     - SEC registration fees

     - fees and expenses of the exchange agent and trustee

     - accounting and legal fees and printing costs

     - related fees and expenses

TRANSFER TAXES

     We will pay all transfer taxes, if any, applicable to the exchange of
outstanding notes under the exchange offer. The tendering holder, however, will
be required to pay any transfer taxes (whether imposed on the registered holder
or any other person) if:

     - certificates representing outstanding notes for principal amounts not
       tendered or accepted for exchange are to be delivered to, or are to be
       issued in the name of, any person other than the registered holder of
       outstanding notes tendered or

     - tendered outstanding notes are registered in the name of any person other
       than the person signing the letter of transmittal or

     - a transfer tax is imposed for any reason other than the exchange of
       outstanding notes under the exchange offer

     If satisfactory evidence of payment of such taxes is not submitted with the
letter of transmittal, the amount of such transfer taxes will be billed to that
tendering holder.

CONSEQUENCES OF FAILURE TO EXCHANGE

     Holders of outstanding notes who do not exchange their outstanding notes
for exchange notes under the exchange offer will remain subject to the
restrictions on transfer of such outstanding notes:

     - as set forth in the legend printed on the notes as a consequence of the
       issuance of the outstanding notes pursuant to the exemptions from, or in
       transactions not subject to, the registration requirements of the
       Securities Act and applicable state securities laws

     - otherwise set forth in the offering circular distributed in connection
       with the private offering of the outstanding notes

     In general, you may not offer or sell the outstanding notes unless they are
registered under the Securities Act, or if the offer or sale is exempt from
registration under the Securities Act and applicable state securities laws.
Except as required by the registration rights agreement, we do not intend to
register resales of the outstanding notes under the Securities Act. Based on
interpretations of the SEC staff, exchange notes issued pursuant to the exchange
offer may be offered for resale, resold or otherwise transferred by their
holders (other than any such holder that is our "affiliate" within the meaning
of Rule 405 under the Securities Act) without compliance with the registration
and prospectus delivery provisions of the Securities Act, provided that the
holders acquired the exchange notes in the ordinary course of the holders'
business and the holders have no arrangement or understanding with respect to
the distribution of the exchange notes to be acquired in the exchange offer. Any
holder who tenders in the exchange offer for the purpose of participating in a
distribution of the exchange notes:

     - could not rely on the applicable interpretations of the SEC

     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with a secondary resale transaction

                                       41
<PAGE>   46

ACCOUNTING TREATMENT

     We will record the exchange notes in our accounting records at the same
carrying value as the outstanding notes, which is the aggregate principal amount
as reflected in our accounting records on the date of exchange. Accordingly, we
will not recognize any gain or loss for accounting purposes in connection with
the exchange offer. We will record the expenses of the exchange offer as
incurred.

OTHER

     Participation in the exchange offer is voluntary, and you should carefully
consider whether to accept. You are urged to consult your financial and tax
advisors in making your own decision on what action to take.

     We may in the future seek to acquire untendered outstanding notes in open
market or privately negotiated transactions, through subsequent exchange offers
or otherwise. We have no present plans to acquire any outstanding notes that are
not tendered in the exchange offer or to file a registration statement to permit
resales of any untendered outstanding notes.

                            DESCRIPTION OF THE NOTES

GENERAL

     The form and terms of the exchange notes and the outstanding notes are
identical in all material respects, except that the registration rights and
related liquidated damages provisions, and the transfer restrictions applicable
to the outstanding notes, do not apply to the exchange notes. All references to
"Notes" in this section are references to both the outstanding notes and the
exchange notes, unless otherwise specified.

     Express Scripts issued the outstanding 9 5/8% Senior Notes due 2009 (the
"Outstanding Notes") under an Indenture (the "Indenture"), among itself, the
Guarantors and Bankers Trust Company, as trustee (the "Trustee"). The terms of
the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (the "Trust Indenture
Act").

     Certain terms used in this description are defined under the caption
" -- Certain Definitions." In this description, the word "Company" refers only
to Express Scripts and not to any of its subsidiaries.

     The following description is only a summary of the material provisions of
the Indenture and the Registration Rights Agreement. We urge you to read the
Indenture and the Registration Rights Agreement because they, and not this
description, define your rights as holders of these Notes. You may request
copies of these agreements at our address set forth under "Express Scripts."

BRIEF DESCRIPTION OF THESE NOTES

     These Notes:

     - are senior unsecured obligations of the Company

     - are guaranteed on a senior unsecured basis by each of the Guarantors

     - rank equally with all other senior unsecured Indebtedness of the Company
       and the Guarantors

     - rank senior in right of payment to all subordinated Indebtedness of the
       Company and the Guarantors

                                       42
<PAGE>   47

     - are effectively subordinated to the Company's and the Guarantors' secured
       Indebtedness, to the extent of the value of the assets securing such
       Indebtedness

     - will entitle you to the benefits of the Registration Rights Agreement

PRINCIPAL, MATURITY AND INTEREST

     The Company issued the Outstanding Notes initially with an aggregate
principal amount of $250 million. The Company issued the Outstanding Notes in
denominations of $1,000 and any integral multiple of $1,000. The Notes will
mature on June 15, 2009.

     Subject to our compliance with the covenant described under the caption
"-- Limitation on Indebtedness," we are permitted to issue more Notes under the
Indenture in a principal amount of $250 million (the "Additional Notes").

     Interest on these Notes will accrue at the rate of 9 5/8% per annum and
will be payable semiannually in arrears on June 15 and December 15, commencing
on December 15, 1999. The Company will make each interest payment to the holders
of record of these Notes on the immediately preceding June 1 and December 1.

     Interest on these Notes will accrue from the date of original issuance or,
if interest has already been paid, from the date it was most recently paid.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.

     Additional interest may accrue on the Notes in certain circumstances
pursuant to the Registration Rights Agreement.

OPTIONAL REDEMPTION

     Except as set forth below, we will not be entitled to redeem the Notes at
our option prior to June 15, 2004. On and after June 15, 2004, we will be
entitled at our option to redeem all or a portion of these Notes upon not less
than 30 nor more than 60 days' notice at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest thereon, if any, to the applicable redemption date, if redeemed during
the 12-month period beginning on June 15 in the years indicated below:

2007 and thereafter.................................   100.0000%
</TABLE>

     In addition, before June 15, 2002, we may at our option on one or more
occasions redeem up to 35% of the original principal amount of Notes (including
the original principal amount of any Additional Notes) at a redemption price of
109.625% of the principal amount thereof, plus accrued and unpaid interest to
the redemption date, with the net cash proceeds from one or more Public Equity
Offerings; provided that

     (1) at least 65% of the aggregate principal amount of Notes originally
         issued (including the original principal amount of any Additional
         Notes) pursuant to the Indenture remains outstanding immediately after
         the occurrence of each such redemption (other than Notes held, directly
         or indirectly, by the Company or its Affiliates); and

     (2) each such redemption occurs within 120 days after the date of the
         related Public Equity Offering.

                                       43
<PAGE>   48

SELECTION AND NOTICE OF REDEMPTION

     If we are redeeming less than all the Notes at any time, the Trustee will
select Notes on a pro rata basis, by lot or by such other method as the Trustee
in its sole discretion shall deem to be fair and appropriate.

     We will redeem Notes of $1,000 or less in whole and not in part. We will
cause notices of redemption to be mailed by first-class mail at least 30 but not
more than 60 days before the redemption date to each holder of Notes to be
redeemed at its registered address.

     If any Note is to be redeemed in part only, the notice of redemption that
relates to that Note shall state the portion of the principal amount thereof to
be redeemed. We will issue a new Note in principal amount equal to the
unredeemed portion of the original Note in the name of the holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on Notes or portions of them called for redemption.

RANKING

GENERAL

     The Notes rank equally in right of payment with all other senior unsecured
Indebtedness of the Company and the Guarantors. The Notes rank senior in right
of payment to all subordinated Indebtedness of the Company and the Guarantors.
The Notes are effectively subordinated to the Company's and the Guarantors'
secured Indebtedness to the extent of the value of the assets securing such
Indebtedness.

     As of March 31, 1999, after giving effect to the issuance of the Notes and
the application of the proceeds of the Notes, the Company and the Guarantors
would have had approximately $749 million of Indebtedness on a consolidated
basis (before giving effect to the repayment of $25 million of our indebtedness
with available cash), $500 million of which would have been secured Indebtedness
under the Senior Credit Facility. The Senior Credit Facility is secured by all
of the capital stock of certain of the Company's direct and indirect domestic
subsidiaries. Although the Indenture contains limitations on the amount of
additional Indebtedness that the Company may incur, under certain circumstances
the amount of such Indebtedness could be substantial. See "Certain
Covenants -- Limitation on Indebtedness."

LIABILITIES OF SUBSIDIARIES UNDER NOTES

     Claims of creditors of the Company's Subsidiaries, other than the
Guarantors, generally have priority with respect to the assets and earnings of
such Subsidiaries over the claims of creditors of the Company, including holders
of the Notes. Accordingly, the Notes are effectively subordinated to creditors
(including trade creditors) and preferred stockholders, if any, of the Company's
Subsidiaries other than the Guarantors.

     At the Issue Date, all of the Company's Restricted Subsidiaries (other than
Diversified NY IPA and Diversified Pharmaceutical Services (Puerto Rico)) were
Guarantors.

GUARANTEES

     The obligations of the Company pursuant to the Notes, including the
repurchase obligation resulting from a Change of Control, are unconditionally
guaranteed, on a senior unsecured basis, by the Guarantors (each such guarantee,
a "Guarantee"). The Guarantors agree to pay, in addition to the amount stated
above, any and all expenses (including reasonable counsel fees and expenses)
incurred by the Trustee and the Holders

                                       44
<PAGE>   49

in enforcing any rights under the Guarantees. The Guarantees are limited in
amount to an amount not to exceed the maximum amount that can be guaranteed by
the Guarantors, after giving effect to all of their other contingent and fixed
liabilities (including, without limitation, any guarantees under the Senior
Credit Facility), without rendering the Guarantees voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally. If any Guarantee is rendered
voidable, it could be subordinated by a court to all other Indebtedness
(including guarantees and other contingent liabilities) of the relevant
Guarantor, and, depending on the amount of such Indebtedness, the Guarantor's
liability on its Guarantee could be reduced to zero.

     Pursuant to the Indenture, a Guarantor may consolidate with, merge with or
into or transfer all or substantially all its assets to any other Person to the
extent described below under "Certain Covenants -- Merger and Consolidation";
provided, however, that if such other Person is not the Company, such
Guarantor's obligations under its Guarantee must be expressly assumed by such
other Person. However, upon the sale or other disposition (including by way of
consolidation or merger) of all the Capital Stock, or the sale or disposition of
all or substantially all the assets, of a Guarantor (in each case other than to
the Company or an Affiliate of the Company) permitted by the Indenture, such
Guarantor will be released and relieved from all its obligations under the
Indenture and its Guarantee and such Guarantee shall terminate; provided,
however, that if the lenders under the Senior Credit Facility release the
guarantee of YourPharmacy.com, Inc. under the Senior Credit Facility,
YourPharmacy.com, Inc. will be automatically released and relieved of all its
obligations under the Indenture and its Guarantee and such Guarantee will
terminate; provided, further, however, if at any time after such release
YourPharmacy.com, Inc. again becomes a guarantor under the Senior Credit
Facility, the Company shall cause YourPharmacy.com, Inc. to unconditionally
guarantee on a senior basis all of the Company's obligations under the Notes and
the Indenture to the same extent as it guarantees the Company's obligations
under the Senior Credit Facility.

BOOK-ENTRY; DELIVERY AND FORM

     We initially issued the Outstanding Notes and will issue the Exchange Notes
in the form of one or more global notes (collectively, the "Global Note"). The
Global Note is deposited with the Trustee as custodian for DTC and registered in
the name of a nominee of DTC. Except as set forth below, the Global Note may be
transferred, in whole and not in part, only to DTC or another nominee of DTC.
You may hold your beneficial interests in the Global Note directly through DTC
if you have an account with DTC or indirectly through organizations which have
accounts with DTC.

     DTC has advised us as follows: DTC is a limited-purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the New York
Uniform Commercial Code, and "a clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities of institutions that have accounts with DTC ("participants") and to
facilitate the clearance and settlement of securities transactions among its
participants in such securities through electronic book-entry changes in
accounts of the participants, thereby eliminating the need for physical movement
of securities certificates. DTC's participants include securities brokers and
dealers (which may include the initial purchasers), banks, trust companies,
clearing corporations and certain other organizations. Access to DTC's
book-entry system is also available to others such as banks, brokers, dealers
and trust companies (collectively, the "indirect partici-

                                       45
<PAGE>   50

pants") that clear through or maintain a custodial relationship with a
participant, whether directly or indirectly.

     Pursuant to procedures established by DTC, upon the deposit of the Global
Note with DTC, DTC will credit, on its book-entry registration and transfer
system, the principal amount of Notes represented by such Global Note to the
accounts of participants. Ownership of beneficial interests in the Global Note
is limited to participants or persons that may hold interests through
participants. Ownership of beneficial interests in the Global Note is shown on,
and the transfer of those ownership interests will be effected only through,
records maintained by DTC (with respect to participants' interests), the
participants and the indirect participants (with respect to the owners of
beneficial interests in the Global Note other than participants). The laws of
some jurisdictions may require that certain purchasers of securities take
physical delivery of such securities in definitive form. Such limits and laws
may impair the ability to transfer or pledge beneficial interests in the Global
Note.

     So long as DTC, or its nominee, is the registered owner or holder of the
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Notes represented by such Global Note for all
purposes under the Indenture and the Notes. In addition, as a beneficial owner
of an interest in the Global Note, you may not transfer that interest except in
accordance with the applicable procedures of DTC and, if applicable, Morgan
Guaranty Trust Company of New York, as operator of the Euroclear system
("Euroclear"). Except as set forth below, as an owner of a beneficial interest
in the Global Note, you are not entitled to have the Notes represented by the
Global Note registered in your name, you will not receive or be entitled to
receive physical delivery of certificated Notes and you are not considered to be
the owner or holder of any Notes under the Global Note. We understand that under
existing industry practice, in the event an owner of a beneficial interest in
the Global Note desires to take any action that DTC, as the holder of the Global
Note, is entitled to take, DTC would authorize the participants to take such
action, and the participants would authorize beneficial owners owning through
such participants to take such action or would otherwise act upon the
instructions of beneficial owners owning through them.

     We will make payments of principal of, premium, if any, and interest on the
Notes represented by the Global Note registered in the name of and held by DTC
or its nominee to DTC or its nominee, as the case may be, as the registered
owner and holder of the Global Note. Neither we, the Trustee nor any Paying
Agent have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in the
Global Note or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

     We expect that DTC or its nominee, upon receipt of any payment of principal
of, premium, if any, or interest on the Global Note, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of the Global Note as shown on the records of
DTC or its nominee. We also expect that payments by participants or indirect
participants to owners of beneficial interests in the Global Note held through
such participants or indirect participants will be governed by standing
instructions and customary practices and will be the responsibility of such
participants or indirect participants. We will not have any responsibility or
liability for any aspect of the records relating to, or payments made on account
of, beneficial ownership interests in the Global Note for any Note or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests or for any other aspect of the relationship between DTC and
its participants or indirect participants or the

                                       46
<PAGE>   51

relationship between such participants or indirect participants and the owners
of beneficial interests in the Global Note owning through such participants.

     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds. Transfers
between participants in Euroclear will be effected in the ordinary way in
accordance with its rules and operating procedures.

     DTC has advised us that it will take any action permitted to be taken by a
holder of Notes (including the presentation of Notes for exchange as described
below) only at the direction of one or more participants to whose account the
DTC interests in the Global Note is credited and only in respect of such portion
of the aggregate principal amount of Notes as to which such participant or
participants has or have given such direction. However, if there is an Event of
Default under the Notes, DTC will exchange the Global Note for certificated
Notes which it will distribute to its participants.

     Although DTC and Euroclear are expected to follow the foregoing procedures
in order to facilitate transfers of interests in the Global Note among
participants of DTC and Euroclear, they are under no obligation to perform or
continue to perform such procedures, and such procedures may be discontinued at
any time. Neither we nor the Trustee will have any responsibility or liability
for the performance by DTC, Euroclear or the participants or indirect
participants of their respective obligations under the rules and procedures
governing their respective operations.

     DTC management is aware that some computer applications, systems and the
like for processing data ("Systems") that are dependent upon calendar dates,
including dates before, on, and after January 1, 2000, may encounter "Year 2000
problems." DTC has informed its Participants and other members of the financial
community (the "Industry") that it has developed and is implementing a program
so that its Systems, as the same relate to the timely payment of distributors
(including principal and income payments) to securityholders, book-entry
deliveries and settlement of trades within DTC ("DTC Services"), continue to
function appropriately. This program includes a technical assessment and a
remediation plan, each of which is complete. Additionally, DTC's plan includes a
testing phase, which is expected to be completed within appropriate time frames.

     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as third party vendors from whom DTC licenses software and hardware, and
third party vendors on whom DTC relies for information or the provision of
services, including telecommunication and electrical utility service providers,
among others, DTC has informed the Industry that it is contacting (and will
continue to contact) third party vendors from whom DTC acquires services to: (i)
impress upon them the importance of such services being Year 2000 compliant and
(ii) determine the extent of their efforts for Year 2000 remediation (and, as
appropriate, testing) of their services. In addition, DTC is in the process of
developing such contingency plans as it deems appropriate.

CERTIFICATED SECURITIES

     Subject to certain conditions, the Notes represented by the Global Note are
exchangeable for certificated Notes in definitive form of like tenor in
denominations of $1,000 and integral multiples if:

     (1) DTC or any successor depository notifies us in writing that it is no
         longer willing or able to act as a depositary and we are unable to
         locate a qualified successor

                                       47
<PAGE>   52

         within 90 days or if at any time the Depository ceases to be a clearing
         agency registered under the Exchange Act;

     (2) we in our discretion at any time determine not to have all the Notes
         represented by the Global Note; or

     (3) a default entitling the holders of the Notes to accelerate the maturity
         thereof has occurred and is continuing.

     Any Note that is exchangeable pursuant to the preceding paragraph is
exchangeable for certificated Notes issuable in authorized denominations and
registered in such names as DTC shall direct. Subject to the foregoing, the
Global Note is not exchangeable, except for a Global Note of the same aggregate
denomination to be registered in the name of DTC or its nominee.

     Neither we nor the Trustee will be liable for any delay by the related
holder of a Global Note (a "Global Note Holder") or the Depository in
identifying the beneficial owners of the related Notes, and we and the Trustee
may conclusively rely on, and will be protected in relying on, instructions from
such Global Note Holder or of the Depository for all purposes (including with
respect to the registration and delivery, and the respective principal amounts,
of the Notes to be issued).

SAME DAY PAYMENT

     The Indenture requires us to make payments in respect of Notes (including
principal, premium, if any, and interest) by wire transfer of immediately
available funds to the accounts specified by the holders thereof or, if no such
account is specified, by mailing a check to each such holder's registered
address.

REGISTERED EXCHANGE OFFER; REGISTRATION RIGHTS

     We and the Guarantors have agreed pursuant to a Registration Rights
Agreement that we and the Guarantors will, at our cost:

     (1) within 60 days after the Issue Date, file a registration statement (the
         "Exchange Offer Registration Statement") with the SEC with respect to a
         registered offer (the "Registered Exchange Offer") to exchange the
         Outstanding Notes for new notes (the "Exchange Notes") having terms
         substantially identical in all material respects to the Outstanding
         Notes and guaranteed by each of the Guarantors except that the Exchange
         Notes will not contain terms with respect to transfer restrictions;

     (2) use our reasonable best efforts to cause the Exchange Offer
         Registration Statement to be declared effective under the Securities
         Act within 180 days after the Issue Date;

     (3) as soon as practicable after the effectiveness of the Exchange Offer
         Registration Statement (the "Effectiveness Date"), to offer the
         Exchange Notes in exchange for surrender of the Outstanding Notes; and

     (4) to keep the Registered Exchange Offer open for not less than 30 days
         (or longer if required by applicable law) after the date notice of the
         Registered Exchange Offer is mailed to the holders of the Outstanding
         Notes.

     For each Outstanding Note surrendered to us pursuant to the Registered
Exchange Offer, we will issue to the holder of such Outstanding Note an Exchange
Note having a principal amount equal to that of the surrendered Outstanding
Note. Interest on each Exchange Note will accrue from the last interest payment
date on which interest was paid on the Outstanding Note surrendered in exchange
thereof or, if no interest has been paid

                                       48
<PAGE>   53

on such Outstanding Note, from the date interest begins to accrue on such
Outstanding Note.

     Under existing SEC interpretations, the Exchange Notes will be freely
transferable by holders other than our affiliates after the Registered Exchange
Offer without further registration under the Securities Act if the holder of the
Exchange Notes represents to us in the Registered Exchange Offer that it is
acquiring the Exchange Notes in the ordinary course of its business, that it has
no arrangement or understanding with any person to participate in the
distribution of the Exchange Notes and that it is not an affiliate of ours, as
such terms are interpreted by the SEC; provided, however, that broker-dealers
("Participating Broker-Dealers") receiving Exchange Notes in the Registered
Exchange Offer will have a prospectus delivery requirement with respect to
resales of such Exchange Notes. The SEC has taken the position that
Participating Broker-Dealers may fulfill their prospectus delivery requirements
with respect to Exchange Notes (other than a resale of an unsold allotment from
the original sale of the Outstanding Notes) with the prospectus contained in the
Exchange Offer Registration Statement.

     Under the Registration Rights Agreement, we are required to allow
Participating Broker-Dealers and other persons, if any, with similar prospectus
delivery requirements to use the prospectus contained in the Exchange Offer
Registration Statement in connection with the resale of such Exchange Notes for
180 days following the effective date of such Exchange Offer Registration
Statement (or such shorter period during which Participating Broker-Dealers are
required by law to deliver such prospectus).

     In the event that applicable interpretations of the staff of the SEC do not
permit us to effect such a Registered Exchange Offer, or if for any other reason
we do not consummate the Registered Exchange Offer no later than 220 days after
the date of original issuance of the outstanding Notes, or if an initial
purchaser shall notify us within 10 business days following consummation of the
Registered Exchange Offer that Outstanding Notes held by it are not eligible to
be exchanged for Exchange Notes in the Registered Exchange Offer, or if any
holder of Outstanding Notes shall notify us that:

     (1) such holder is prohibited by law or SEC policy from participating in
         the Registered Exchange Offer;

     (2) such holder may not resell the Exchange Notes acquired by it in the
         Registered Exchange Offer to the public without delivering a prospectus
         and the prospectus contained in the Exchange Offer Registration
         Statement is not appropriate or available for such resales by such
         holder; or

     (3) such holder is a broker-dealer and holds Outstanding Notes that are
         part of an unsold allotment from the original sale of the Outstanding
         Notes,

then, we and the Guarantors will, at our cost,

     (1) as promptly as practicable, file a shelf registration statement (the
         "Shelf Registration Statement") with the SEC covering resales of the
         Notes or the Exchange Notes, as the case may be;

     (2) use our reasonable best efforts to cause the Shelf Registration
         Statement to be declared effective under the Securities Act; and

     (3) keep the Shelf Registration Statement effective until the earlier of
         (a) the time when the Outstanding Notes covered by the Shelf
         Registration Statement can be sold pursuant to Rule 144 without any
         limitations under clauses (c), (e), (f) and (h) of Rule 144 and (b) two
         years from the Issue Date.

                                       49
<PAGE>   54

     We will, in the event a Shelf Registration Statement is filed, among other
things, provide to each holder for whom such Shelf Registration Statement was
filed copies of the prospectus which is a part of the Shelf Registration
Statement, notify each such holder when the Shelf Registration Statement has
become effective and take certain other actions as are required to permit
unrestricted resales of the Outstanding Notes or the Exchange Notes, as the case
may be. A holder selling such Outstanding Notes or Exchange Notes pursuant to
the Shelf Registration Statement generally would be required to be named as a
selling security holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Rights Agreement which are applicable to such
holder (including certain indemnification obligations).

     We will pay additional cash interest on the Notes if:

     (1) by August 15, 1999 (60 days after the Issue Date), neither the Exchange
         Offer Registration Statement nor the Shelf Registration Statement has
         been filed with the SEC;

     (2) by January 22, 2000 (220 days after the Issue Date), neither the
         Registered Exchange Offer is consummated nor the Shelf Registration
         Statement is declared effective; or

     (3) after either the Exchange Offer Registration Statement or the Shelf
         Registration Statement is declared effective, such Registration
         Statement thereafter ceases to be effective or usable (subject to
         certain exceptions),

(each such event referred to in clauses (1) through (3) above, a "Registration
Default") from and including the date on which any such Registration Default
shall occur to but excluding the date on which all Registration Defaults have
been cured.

     The rate of additional interest will be at the rate of 0.25% per annum for
the first 90-day period immediately following the occurrence of such
Registration Default regardless of the number of such Registration Defaults (and
such rate will increase by an additional 0.25% per annum with respect to each
subsequent 90-day period), until all Registration Defaults have been cured, up
to a maximum additional interest rate of 0.50% per annum. We will pay such
additional interest on regular interest payment dates. Such additional interest
will be in addition to any other interest payable from time to time with respect
to the Outstanding Notes and the Exchange Notes.

     All references in the Indenture, in any context, to any payment of
principal, purchase prices in connection with a purchase of Notes, and interest
or any other amount payable on or with respect to any of the Notes shall be
deemed to include payment of any additional cash interest pursuant to the
Registration Rights Agreement.

     If we effect the Registered Exchange Offer, we will be entitled to close
the Registered Exchange Offer 30 days after the commencement thereof provided
that we have accepted all Outstanding Notes theretofore validly tendered in
accordance with the terms of the Registered Exchange Offer.

     This summary of certain provisions of the Registration Rights Agreement is
subject to, and is qualified in its entirety by reference to, all the provisions
of the Registration Rights Agreement, a copy of which is available from us upon
request.

CHANGE OF CONTROL

     Upon the occurrence of any of the following events (each a "Change of
Control"), each Holder shall have the right to require that we purchase all or a
part of such Holder's Notes at a purchase price in cash equal to 101% of the
principal amount thereof plus accrued and unpaid interest, if any, to the date
of purchase:

     (1) any "person" (as such term is used in Sections 13(d) and 14(d) of the
         Exchange Act) or any two or more such persons acting in concert, other
         than one or more Permitted Holders, becomes the beneficial owner
         (within the meaning of Rule 13d-3 of the Exchange Act), directly or
         indirectly, of more than 35% of the total voting power of the then
         outstanding Voting Stock of the Company and the Permitted Holders
         beneficially own (within the meaning of Rule 13d-3 of the Exchange
         Act), directly or indirectly, a lesser percentage of the total voting
         power of the outstanding Voting Stock of the Company than such person
         or persons; provided, that the acquisition of beneficial ownership of
         shares of Voting Stock of the Company beneficially owned (or which
         immediately prior to such acquisition were beneficially owned) by a
         Permitted Holder by one or more Persons from time to time shall not
         constitute a Change of Control;

     (2) if the Permitted Holders do not beneficially own (within the meaning of
         Rule 13d-3 under the Exchange Act), directly or indirectly, more than
         50% of the total voting power of the then outstanding Voting Stock of
         the Company, during any period of two consecutive years, individuals
         who at the beginning of such period constituted the Board of Directors
         of the Company (together with any new directors whose election by such
         Board of Directors or whose nomination for election by the shareholders
         of the Company was approved by a vote of the majority of the directors
         of the Company then still in office who were either directors at the
         beginning of such period or whose election or nomination for election
         was previously so approved) cease for any reason to constitute a
         majority of the Board of Directors of the Company then in office;

     (3) the adoption by the holders of Capital Stock of the Company of any plan
         or proposal for the liquidation or dissolution of the Company (whether
         or not otherwise in compliance with the Indenture); or

     (4) the merger or consolidation of the Company with or into another Person
         or the merger of another Person with or into the Company, or the sale
         of all or substantially all the assets of the Company and its
         Subsidiaries, taken as a whole, to another Person (other than to a
         Wholly Owned Subsidiary of the Company), and, in the case of any such
         merger or consolidation, the securities of the Company that are
         outstanding immediately prior to such transaction and which represent
         100% of the aggregate voting power of the Voting Stock of the Company
         are changed into or exchanged for cash, securities or property, unless
         pursuant to such transaction such securities are changed into or
         exchanged for, in addition to any other consideration, securities of
         the surviving corporation that represent immediately after such
         transaction (a) at least 35% of the aggregate voting power of the
         Voting Stock of the surviving corporation and (b) a greater percentage
         of the aggregate voting power of the Voting Stock of the surviving
         corporation than the percentage of the aggregate voting power of the
         Voting Stock beneficially owned by any other "person" (as such term is
         used in Section 13(d) and 14(d) under the Exchange Act) or any other
         two or more such persons acting in concert.

                                       51
<PAGE>   56

     Within 30 days following any Change of Control (unless the Company shall
have provided an irrevocable redemption notice to the Trustee with respect to a
redemption of all outstanding Notes at a time when such redemption is permitted
under the Indenture), the Company shall mail a notice to each Holder with a copy
to the Trustee (the "Change of Control Offer") stating:

     (1) that a Change of Control has occurred and that such Holder has the
         right to require the Company to purchase such Holder's Notes at a
         purchase price in cash equal to 101% of the principal amount thereof
         plus accrued and unpaid interest, if any, to the date of purchase;

     (2) the circumstances and relevant facts regarding such Change of Control
         (including information with respect to pro forma historical income,
         cash flow and capitalization after giving effect to such Change of
         Control);

     (3) the purchase date (which shall be no earlier than 30 days nor later
         than 60 days from the date such notice is mailed); and

     (4) the instructions determined by the Company, consistent with the
         covenant described hereunder, that a Holder must follow in order to
         have its Notes purchased.

     The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Company and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.

     The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the purchase of Notes pursuant to the covenant described
hereunder. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of the covenant described hereunder,
the Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the covenant
described hereunder by virtue thereof.

     Subject to the limitations discussed below, the Company could, in the
future, enter into certain transactions, including acquisitions, refinancings or
other recapitalizations, that would not constitute a Change of Control under the
Indenture, but that could increase the amount of indebtedness outstanding at
such time or otherwise affect the Company's capital structure or credit ratings.
Restrictions on the ability of the Company and its Restricted Subsidiaries to
incur additional Indebtedness are contained in the covenant described under
"-- Limitation on Indebtedness." Such restrictions can only be waived with the
consent of the Holders of a majority in principal amount of the Notes then
outstanding. Except for the limitations contained in such covenants, however,
the Indenture will not contain any covenants or provisions that may afford
holders of the Notes protection in the event of a highly leveraged transaction.

     The Senior Credit Facility contains, and future indebtedness of the Company
may contain, prohibitions on the occurrence of certain events that would
constitute a Change of Control or require such indebtedness to be repurchased
upon a Change of Control. Moreover, the exercise by the Holders of their right
to require the Company to purchase the Notes could cause a default under such
indebtedness, even if the Change of Control itself does not, due to the
financial effect of such purchase on the Company. Finally, the Company's ability
to pay cash to the holders of the Notes following the occurrence of a Change of
Control may be limited by the Company's then existing financial resources.

                                       52
<PAGE>   57

There can be no assurance that sufficient funds will be available when necessary
to make any required repurchases. For more details, see "Risk
Factors -- Limitations on Repurchases of Notes Upon a Change of Control."

     The provisions under the Indenture relating to the Company's obligation to
make an offer to purchase the Notes as a result of a Change of Control may be
waived or modified with the written consent of the holders of a majority in
principal amount of the Notes.

     The Change of Control purchase feature of the Notes may make more difficult
or discourage a takeover of the Company and, thus, the removal of incumbent
management.

     The phrase "all or substantially all" of our assets will likely be
interpreted under applicable state law and will be dependent upon particular
facts and circumstances. As a result, there may be a degree of uncertainty in
ascertaining whether a sale or transfer of "all or substantially all" of our
assets has occurred.

CERTAIN COVENANTS

     COVENANT REMOVAL.  Set forth below are summaries of certain covenants
contained in the Indenture. From and after the time that (a) the Notes have
Investment Grade Ratings from both Rating Agencies and (b) there shall not exist
a Default or Event of Default under the Indenture, the Company and the
Restricted Subsidiaries will not be subject to the provisions of the Indenture
applicable to them described under "Limitation on Indebtedness" (including the
application of paragraph (a) thereof pursuant to clause (x) to the proviso to
the third sentence in the definition of "Unrestricted Subsidiary"), "Limitation
on Restricted Payments," "Limitation on Sale or Issuance of Capital Stock of
Restricted Subsidiaries," "Limitation on Sales of Assets and Subsidiary Stock,"
"Limitation on Transactions with Affiliates," "Limitation on Restrictions on
Distributions from Restricted Subsidiaries," clauses (2) and (3) of the first
paragraph and clause (2) of the fourth paragraph under "Merger and
Consolidation" and "Future Guarantors" (collectively, the "Suspended
Covenants"). In addition, the Restricted Subsidiaries shall be released from
their Guarantees at the time referred to in the preceding sentence.

     The Indenture contains covenants including, among others, the following:

LIMITATION ON INDEBTEDNESS.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
Incur, directly or indirectly, any Indebtedness; provided, however, that the
Company and the Restricted Subsidiaries may Incur Indebtedness if, on the date
of such Incurrence and after giving effect thereto, the Consolidated Coverage
Ratio exceeds 2.50 to 1.

     (b) Notwithstanding the foregoing paragraph (a), the Company and the
Restricted Subsidiaries may Incur any or all of the following Indebtedness:

     (1) Indebtedness of the Company and the Guarantors incurred pursuant to the
         Senior Credit Facility; provided, however, that, after giving effect to
         any such Incurrence, the aggregate principal amount of such
         Indebtedness then outstanding does not exceed (a) in the case of the
         term loan facilities, $406 million at any one time outstanding and (b)
         in the case of the revolving loan facility, the sum of (x) the greater
         of (i) $300 million at any one time outstanding and (ii) the sum of (A)
         50% of the book value of the inventory of the Company and its
         Restricted Subsidiaries and (B) 75% of the book value of the accounts
         receivables of the Company and its Restricted Subsidiaries and (y) any
         amount permitted to be incurred pursuant to clause (a) of this
         paragraph (1) but not outstanding thereunder;

         Subsidiary; provided, however, that (i) any subsequent issuance or
         transfer of any Capital Stock which results in any such Restricted
         Subsidiary ceasing to be a Restricted Subsidiary or any subsequent
         transfer of such Indebtedness (other than to the Company or a
         Restricted Subsidiary) shall be deemed, in each case, to constitute the
         Incurrence of such Indebtedness by the obligor thereon and (ii) if the
         Company is the obligor on such Indebtedness, such Indebtedness is
         expressly subordinated to the prior payment in full in cash of all

         days of incurrence;

     (8) Indebtedness of the Company or any of its Restricted Subsidiaries in
         order to finance insurance premiums and other Indebtedness represented
         by letters of credit for the account of the Company or such Restricted
         Subsidiary, as the case may be, in order to provide security for
         workers' compensation claims or payment obligations in connection with
         self-insurance or similar requirements, all in the ordinary course of
         business and so long as such Indebtedness is not an obligation for

          Subsidiaries, other than guarantees of Indebtedness incurred by any
          Person acquiring all or any portion of such business, assets or
          Restricted Subsidiary for the purpose of financing such acquisition;
          provided, however, that the maximum assumable liability in respect of
          all such Indebtedness shall at no time exceed the gross proceeds
          actually received by the Company and its Restricted Subsidiaries in
          connection with such disposition;

          one time outstanding under this clause (13).

     (c) Notwithstanding the foregoing, neither the Company nor any Restricted
Subsidiary shall Incur any Indebtedness pursuant to the foregoing paragraph (b)
if the proceeds thereof are used, directly or indirectly, to Refinance any
Subordinated Obligations unless such Indebtedness shall be subordinated to the
Notes or the Guarantees, as applicable, to at least the same extent as such
Subordinated Obligations.

     (d) For purposes of determining compliance with the foregoing covenant, (1)
in the event that an item of Indebtedness meets the criteria of more than one of
the types of Indebtedness described above, the Company, in its sole discretion,

Subsidiaries to, directly or indirectly, create, incur, assume or permit to
exist any Lien upon or with respect to any of the assets of the Company or any
such Restricted Subsidiary, whether now owned or hereafter acquired, or on any
income or profits therefrom, other than Liens which constitute Permitted Liens
at the date such Liens are created, unless contemporaneously therewith or prior
thereto all payments due under the Indenture and the Notes are secured on an
equal and ratable basis with the obligation or liability so secured until such
time as such obligation or liability is no longer secured by a Lien.

LIMITATION ON RESTRICTED PAYMENTS.

     (a) The Company will not, and will not permit any Restricted Subsidiary,
directly or indirectly, to make a Restricted Payment if at the time the Company
or such Restricted Subsidiary makes such Restricted Payment:

     (1) a Default shall have occurred and be continuing (or would result
         therefrom);

     (2) the Company is not able to Incur an additional $1.00 of Indebtedness
         pursuant to paragraph (a) of the covenant described under "Limitation
         on Indebtedness"; or

<PAGE>   60

     (3) the aggregate amount of such Restricted Payment and all other
         Restricted Payments since the Issue Date would exceed the sum of:

        (A) 50% of the Consolidated Net Income accrued during the period
            (treated as one accounting period) from the beginning of the fiscal
            quarter immediately following the Issue Date to the end of the most
            recent fiscal quarter for which financial statements are available
            ending prior to the date of such Restricted Payment (or, in case
            such Consolidated Net Income shall be a deficit, minus 100% of such
            deficit);

        (B) the aggregate Net Cash Proceeds and the fair market value (as
            determined in good faith by the Board of Directors of the Company)

            capital contributions or the issuance or sale of its Capital Stock
            (other than Disqualified Capital Stock) subsequent to the Issue Date
            (other than an issuance or sale to a Subsidiary of the Company and
            other than an issuance or sale to an employee stock ownership plan
            or to a trust established by the Company or any of its Subsidiaries
            for the benefit of their employees to the extent such sale is
            financed by loans from or guaranteed by the Company unless such
            loans have been repaid with cash on or prior to the date of
            determination);

        (C) the amount by which Indebtedness of the Company or its Restricted
            Subsidiaries (other than Indebtedness owed to the Company or a
            Restricted Subsidiary) is reduced on the Company's balance sheet
            upon the conversion or exchange (other than by a Subsidiary of the
            Company) subsequent to the Issue Date of any Indebtedness of the
            Company or its Restricted Subsidiaries convertible or exchangeable
            for Capital Stock (other than Disqualified Capital Stock) of the
            Company (less the amount of any cash, or the fair value of any other
            property, distributed by the Company upon such conversion or
            exchange); and

        (D) an amount equal to the sum of (1) the net reduction in Investments
            made after the Issue Date in Unrestricted Subsidiaries and other
            Persons constituting Restricted Payments, excluding Investments made
            pursuant to clause (b)(7) or (b)(8) below, resulting from dividends,
            repayments of loans or advances or other transfers of assets, in
            each case to the Company or any Restricted Subsidiary from such
            Unrestricted Subsidiaries or other Persons or received by the
            Company or any Restricted Subsidiary from the disposition of any
            such Investment, and (2) the portion, proportionate to the Company's
            equity interest, of the fair market value of the net assets of an
            Unrestricted Subsidiary or other Person at the time such
            Unrestricted Subsidiary is designated a Restricted Subsidiary or
            such other Person becomes a Restricted Subsidiary, but only to the
            extent of Investments made in such Unrestricted Subsidiary or other
            Person after the Issue Date and in any event excluding Investments
            made pursuant to clause (b)(7) or (b)(8) below; provided, however,
            that the foregoing sum shall not exceed the aggregate amount of
            Investments made after the Issue Date and treated as Restricted
            Payments by the Company or any Restricted Subsidiary.

     (b) The provisions of the foregoing paragraph (a) shall not prohibit:

     (1) any redemption, repurchase or other acquisition of any Capital Stock or
         Subordinated Obligations of the Company made out of the proceeds of the
         substantially concurrent sale of, or made by exchange for, Capital
         Stock of the

         Stock issued or sold to a Subsidiary of the Company or an employee
         stock ownership plan or to a trust established by the Company or any of
         its Subsidiaries for the benefit of their employees to the extent such
         sale is financed by loans from or guaranteed by the Company unless such
         loans have been repaid with cash on or prior to the date of
         determination); provided, however, that the Net Cash Proceeds from such
         sale shall be excluded from the calculation of amounts under clause
         (3)(B) of paragraph (a) above;

     (2) any purchase, repurchase, redemption, defeasance or other acquisition
         or retirement for value of Subordinated Obligations made by exchange
         for, or out of the proceeds of the substantially concurrent sale of,
         Subordinated Obligations of the Company which is permitted to be
         Incurred pursuant to the covenant described under "Limitation on
         Indebtedness";

         at such date of declaration such dividend would have complied with this
         covenant;

     (4) repurchases by the Company of its Capital Stock (i) from employees of
         the Company or any of its Subsidiaries or their authorized
         representatives upon the death, disability or termination of employment
         of such employees or pursuant to any employment agreement between the
         Company and such employee, in an amount not to exceed $5 million in any
         calendar year and $10 million in the aggregate, plus the aggregate cash
         proceeds from any reissuance during such calendar year of its Capital
         Stock by the Company to employees, officers or directors of the Company
         and its Subsidiaries (without duplication of amounts included in clause
         (3)(B) of paragraph (a) above) and (ii) from its Chief Executive
         Officer upon death, disability or termination of employment of such
         Chief Executive Officer or pursuant to any employment agreement between
         the Company and such Chief Executive Officer but only up to the amount
         of the Capital Stock owned by such Chief Executive Officer on the Issue
         Date;

     (5) so long as no Default or Event of Default has occurred and is
         continuing, the declaration and payment of dividends to holders of any
         class or series of Disqualified Capital Stock of the Company issued in
         compliance with the terms of the Indenture to the extent such dividends
         are included in the definition of "Consolidated Interest Expense";

     (6) repurchases of Capital Stock deemed to occur upon the exercise of stock
         options if such Capital Stock represents a portion of the exercise
         price thereof;

     (7) so long as no Default shall have occurred or be continuing or would
         result therefrom, Investments in an aggregate amount outstanding at any

         result therefrom, the making of Restricted Payments in an aggregate
         amount not to exceed $50 million.

     In determining the aggregate amount of Restricted Payments made subsequent
to the Issue Date in accordance with clause (a)(3) above, amounts expended
pursuant to clauses (3), (4), (7) and (8) (but not pursuant to clauses (1), (2),
(5) and (6)) of the immediately preceding paragraph shall be included in such
calculation.

LIMITATION ON RESTRICTIONS ON DISTRIBUTIONS FROM RESTRICTED SUBSIDIARIES.

     The Company will not, and will not permit any Restricted Subsidiary to,
create or otherwise cause or permit to exist or become effective any encumbrance
or restriction on the ability of any Restricted Subsidiary to (a) pay dividends
or make any other distributions on its Capital Stock to the Company or a
Restricted Subsidiary or pay any Indebtedness owed to the Company or a
Restricted Subsidiary, (b) make any loans or advances to the Company or a
Restricted Subsidiary or (c) transfer any of its property or assets to the
Company or a Restricted Subsidiary, except:

     (1) any encumbrance or restriction pursuant to an agreement in effect at or
         entered into on the Issue Date as in effect on the Issue Date;

     (2) any encumbrance or restriction with respect to a Restricted Subsidiary
         pursuant to an agreement relating to any Indebtedness Incurred by such
         Restricted Subsidiary on or prior to the date on which such Restricted
         Subsidiary was acquired by the Company (other than Indebtedness
         Incurred as consideration of, or to provide all or any portion of the
         funds or credit support utilized to consummate, the transaction or
         series of related transactions pursuant to which such Restricted
         Subsidiary became a Restricted Subsidiary or was acquired by the
         Company) and outstanding on such date;

         contained in any amendment to an agreement referred to in clause (1) or
         (2) of this covenant or this clause (3); provided, however, that the
         encumbrances and restrictions with respect to such Restricted
         Subsidiary contained in any such refinancing agreement or amendment are
         no less favorable in the aggregate to the Holders than encumbrances and
         restrictions with respect to such Restricted Subsidiary contained in
         such predecessor agreements;

     (4) any such encumbrance or restriction consisting of customary
         non-assignment provisions in leases governing leasehold interests to
         the extent such provisions restrict the transfer of the lease or the
         property leased thereunder;

     (5) in the case of clause (c) above, restrictions contained in security
         agreements or mortgages securing Indebtedness of a Restricted
         Subsidiary to the extent such restrictions restrict the transfer of the
         property subject to such security agreements or mortgages;

     (6) any restriction with respect to a Restricted Subsidiary imposed
         pursuant to an agreement entered into for the sale or disposition of
         all or substantially all the Capital Stock or assets of such Restricted
         Subsidiary pending the closing of such sale or disposition;

     (7) purchase money obligations for property acquired in the ordinary course
         of business that impose restrictions of the nature described in clause

         law, rule, regulation or order.

LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, consummate any Asset Disposition unless:

     (1) the Company or such Restricted Subsidiary receives consideration at the
         time of such Asset Disposition at least equal to the fair market value
         (including the value of all non-cash consideration), as determined in
         good faith by the Board of Directors of the Company or such Restricted
         Subsidiary, as the case may be, of the shares and assets subject to
         such Asset Disposition;

     (2) at least 75% of the consideration thereof received by the Company or
         such Restricted Subsidiary is in the form of cash or cash equivalents;
         and

     (3) an amount equal to 100% of the Net Available Cash from such Asset
         Disposition is applied by the Company (or such Restricted Subsidiary,
         as the case may be)

        (A) first, to either (x) (i) prepay the Senior Credit Facility (and
            permanently reduce the commitments thereunder) and/or (ii) prepay,
            repay, redeem or purchase (and permanently reduce the commitments
            under) any other Indebtedness (other than any Disqualified Capital
            Stock) of the Company which ranks equally in right of payment with
            the Notes or Indebtedness (other than Disqualified Capital Stock) of
            a Restricted Subsidiary (in each case other than Indebtedness owed
            to the Company or an Affiliate of the Company) in an amount not to
            exceed the Other Senior Debt Pro Rata Share or (y) acquire
            Additional Assets, in each case within one year from the later of
            the date of such Asset Disposition or the receipt of such Net
            Available Cash;

        (B) second, to the extent of the balance of such Net Available Cash
            after application in accordance with clause (A) above, to make an
            offer pursuant to paragraph (b) below to the Holders to purchase
            Notes pursuant to and subject to the conditions contained in the
            Indenture; and

        (C) third, to the extent of the balance of such Net Available Cash after
            application in accordance with clauses (A) or (B) above, to any
            other application or use not prohibited by the Indenture.

     Notwithstanding the foregoing provisions of this paragraph, the Company and
the Restricted Subsidiaries shall not be required to apply any Net Available
Cash in accordance with this paragraph (b) except to the extent that the
aggregate Net Available Cash from all Asset Dispositions which is not applied in
accordance with this paragraph exceeds $20 million (at which time, the entire
unutilized Net Available Cash, and not just the amount in excess of $20 million,
shall be applied pursuant to this paragraph).

     For the purposes of this covenant, the following are deemed to be cash or
cash equivalents: (x) the assumption of Indebtedness of the Company or any
Restricted Subsidiary (other than Subordinated Obligations) and the release of
the Company or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Disposition and (y) securities
received by the Company or any Restricted Subsidiary from the transferee that
are converted by the Company or such Restricted Subsidiary into cash within 90
days of closing the transaction.

     (b) In the event of an Asset Disposition that requires the purchase of the
Notes pursuant to clause (a)(3)(B) above, the Company will be required to
purchase Notes tendered pursuant to an offer by the Company for the Notes at a
purchase price of 100% of their principal amount (without premium) plus accrued
but unpaid interest, if any, in

                                       59
<PAGE>   64

accordance with the procedures (including prorating in the event of over
subscription) set forth in the Indenture.

     (c) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this clause by virtue thereof.

LIMITATION ON TRANSACTIONS WITH AFFILIATES.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
enter into or permit to exist any transaction (including the purchase, sale,
lease or exchange of any property or the rendering of any service) with, or for
the benefit of, any Affiliate of the Company (an "Affiliate Transaction") unless
the terms thereof:

     (1) are no less favorable to the Company or such Restricted Subsidiary than
         those that could be obtained at the time of such transaction in a
         comparable transaction on an arm's-length basis with a Person who is
         not such an Affiliate;

     (2) if such Affiliate Transaction (or series of related Affiliate
         Transactions) involves an amount in excess of $5.0 million (i) are set
         forth in writing and (ii) have been approved by a majority of the
         members of the Board of Directors having no personal stake in such
         Affiliate Transaction; and

     (3) if such Affiliate Transaction (or series of related Affiliate
         Transactions) involves an amount in excess of $10.0 million, have been
         determined by a nationally recognized investment banking firm to be no
         less favorable in any material respect to the Company or such
         Restricted Subsidiary than that which would have been obtained in a
         comparable transaction with an unrelated Person.

     (b) The provisions of the foregoing paragraph (a) shall not prohibit:

     (1) any Permitted Investment or Restricted Payment not otherwise prohibited
         pursuant to the covenant described under "Limitation on Restricted
         Payments";

     (2) any issuance of securities, or other payments, awards or grants in
         cash, securities or otherwise pursuant to, or the funding of,
         employment arrangements, stock options and stock ownership plans
         entered into in the ordinary course of business and approved by the
         Board of Directors of the Company;

     (3) reasonable fees and compensation paid to and indemnity provided on
         behalf of officers, directors, employees, agents or consultants of the
         Company or any Restricted Subsidiary of the Company as determined in
         good faith by the Company's Board of Directors;

     (4) any Affiliate Transaction exclusively between the Company and a
         Restricted Subsidiary or exclusively between Restricted Subsidiaries;
         and

     (5) the issuance or sale of any Capital Stock (other than Disqualified
         Capital Stock) of the Company.

     The Company will not sell or otherwise dispose of any Capital Stock of a
Restricted Subsidiary, and will not permit any Restricted Subsidiary, directly
or indirectly, to issue or sell or otherwise dispose of any of its Capital Stock
except:

     (1) to the Company or a Restricted Subsidiary;

     (2) directors' qualifying shares or shares required by applicable law to be
         held by a Person other than the Company or a Restricted Subsidiary;

     (3) in compliance with or to the extent not restricted by the covenant
         described under "-- Limitation on Sales of Assets and Subsidiary Stock"
         and immediately after giving effect to such issuance or sale, such
         Restricted Subsidiary either continues to be a Restricted Subsidiary or
         if such Restricted Subsidiary would no longer be a Restricted
         Subsidiary, then the Investment of the Company in such Person (after
         giving effect to such issuance or sale) would have been permitted to be
         made under the "-- Limitation on Restricted Payments" covenant as if
         made on the date of such issuance or sale.

     Notwithstanding the preceding paragraph, the Company may sell all the
Voting Stock of a Restricted Subsidiary as long as the Company complies with the
terms of the covenant described under "-- Limitation on Sales of Assets and
Subsidiary Stock."

MERGER AND CONSOLIDATION.

     The Company will not consolidate with or merge with or into, or convey,
transfer or lease, in one transaction or a series of transactions, its assets
substantially as an entirety to, any Person, unless:

     (1) either the Company shall be the surviving Person, or the resulting,
         surviving or transferee Person (the "Successor Company") shall be a
         corporation organized and existing under the laws of the United States
         of America, any State thereof or the District of Columbia and the
         Successor Company (if not the Company) shall expressly assume, by an
         indenture supplemental thereto, executed and delivered to the Trustee,
         in form satisfactory to the Trustee, all the obligations of the Company
         under the Notes, the Indenture and the Registration Rights Agreement;

     (2) immediately after giving effect to such transaction (and treating any
         Indebtedness which becomes an obligation of the Successor Company or
         any Restricted Subsidiary as a result of such transaction as having
         been Incurred by such Successor Company or such Restricted Subsidiary
         at the time of such transaction), no Default shall have occurred and be
         continuing; and

     (3) immediately after giving effect to such transaction, the Successor
         Company would be able to Incur an additional $1.00 of Indebtedness
         pursuant to paragraph (a) of the covenant described under "Limitation
         on Indebtedness."

     The Successor Company shall be the successor to the Company and shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture, but in the case of a conveyance, transfer or
lease, the Company shall not be released from the obligation to pay the
principal of and interest on the Notes.

     Notwithstanding the foregoing, (1) any Restricted Subsidiary may
consolidate with, merge into or transfer all or part of its properties and
assets to the Company and (2) the Company may merge with an Affiliate
incorporated for the purpose of reincorporating the Company in another
jurisdiction to realize tax or other benefits.

                                       61
<PAGE>   66

     The Company will not permit any Guarantor to consolidate with or merge with
or into, or convey, transfer, lease, in one transaction or a series of
transactions, all or substantially all of its assets to, any Person unless:

     (1) the resulting, surviving or transferee Person shall be a corporation
         organized and existing under the laws of the jurisdiction under which
         the Guarantor was organized or under the laws of the United States of
         America, any State thereof or the District of Columbia, and such Person
         (if not the Guarantor) shall expressly assume, by a supplemental
         indenture, executed and delivered to the Trustee, in a form
         satisfactory to the Trustee, all the obligations of the Guarantor, if
         any, under its Guarantee, the Indenture and the Registration Rights
         Agreement; and

     (2) immediately after giving effect to such transaction (and treating any
         Indebtedness which becomes an obligation of the resulting, surviving or
         transferee Person as a result of such transaction as having been
         Incurred by such Person at the time of such transaction), no Default
         shall have occurred and be continuing.

     The provisions of the immediately preceding clauses (1) and (2) shall not
apply to any transactions that constitute an Asset Disposition if the Company
complied with the applicable provisions of the covenant described under
"Limitation on Sales of Assets and Subsidiary Stock" above and such Asset
Disposition shall not be to an Affiliate of the Company.

     Notwithstanding the foregoing, any Guarantor may merge into or transfer all
or part of its properties and assets to the Company or another Guarantor.

     Although there is a limited body of case law interpreting the phrase
"substantially all," there is no precise established definition of the phrase
under applicable law. Accordingly, in certain circumstances there may be a
degree of uncertainty as to whether a particular transaction would involve "all
or substantially all" of the property or assets of a Person.

FUTURE GUARANTORS

     If the Company or any of its Restricted Subsidiaries transfers or causes to
be transferred, in one transaction or a series of related transactions, any
property to any domestic Restricted Subsidiary that is not the Company or a
Guarantor, or if the Company or any of its Restricted Subsidiaries shall
organize, acquire or otherwise invest in another domestic Restricted Subsidiary,
then such transferee or acquired or other Restricted Subsidiary will (1) by a
supplemental indenture executed and delivered to the Trustee, in form
satisfactory to the Trustee, unconditionally guarantee on a senior basis all of
the Company's obligations under the Notes and the Indenture; and (2) deliver to
the Trustee an officers certificate and an opinion of counsel each stating that
such supplemental indenture complies with the Indenture. Thereafter, such
Restricted Subsidiary shall be a Guarantor for all purposes of the Indenture.

REPORTS

     Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, the Company will file
with the SEC (unless the SEC will not accept such a filing, in which case the
Company will provide such documents to the Trustee) and provide within 15 days
to the Trustee and Holders such annual reports and such information, documents
and other reports as are specified in Sections 13 and 15(d) of the Exchange Act
and applicable to a U.S. corporation subject to such Sections, such information,
documents and other reports to be so filed and

                                       62
<PAGE>   67

provided at the times specified for the filing of such information, documents
and reports under such Sections. In addition, for so long as any Notes remain
outstanding, the Company will furnish to the Holders and to securities analysts
and prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act, and, to any
beneficial owner of Notes, if not obtainable from the SEC, information of the
type that would be filed with the SEC pursuant to the foregoing provisions, upon
the request of any such holder.

DEFAULTS

     Each of the following is an Event of Default:

     (1) a default in the payment of interest on the Notes when due, continued
         for 30 days,

     (2) a default in the payment of principal of any Note when due at its
         Stated Maturity, upon optional redemption, upon required repurchase,
         upon acceleration or otherwise,

     (3) the failure by the Company or any Guarantor to comply with its
         obligations under "Certain Covenants -- Merger and Consolidation"
         above,

     (4) the failure by the Company to comply for 30 days after notice with any
         of its obligations in the covenants described above under "Change of
         Control" (other than a failure to purchase Notes) or under "Certain
         Covenants -- Limitation on Indebtedness," "-- Limitation on Liens,"
         "-- Limitation on Restricted Payments," "-- Limitation on Restrictions
         on Distributions from Restricted Subsidiaries," "-- Limitation on Sales
         of Assets and Subsidiary Stock," "-- Limitation on Transactions with
         Affiliates" or "-- Limitation on the Sale or Issuance of Capital Stock
         of Restricted Subsidiaries,"

     (5) the failure by the Company to comply for 60 days after notice with its
         other agreements contained in the Indenture,

     (6) Indebtedness of the Company or any Restricted Subsidiary is not paid
         within any applicable grace period after final maturity or is
         accelerated by the holders thereof because of a default and the total
         amount of such Indebtedness unpaid or accelerated exceeds $15 million
         (the "cross-acceleration provision"),

     (7) certain events of bankruptcy, insolvency or reorganization of the
         Company, any Guarantor or any Significant Subsidiary (the "bankruptcy
         provisions"),

     (8) any judgment or decree for the payment of money in excess of $15
         million in the aggregate (net of any amounts with respect to which a
         reputable and creditworthy insurance company has acknowledged liability
         in writing) is entered against the Company, any Guarantor or any
         Significant Subsidiary, remains outstanding for a period of 60 days
         following entry of such judgment and is not discharged, bonded, waived
         or stayed within 30 days after notice (the "judgment default
         provision"), or

     (9) a Guarantee ceases to be in full force and effect or is declared to be
         null and void and unenforceable or the Guarantee is found to be invalid
         or a Guarantor denies its liability under its Guarantee (other than by
         reason of release of the Guarantor in accordance with the terms of the
         Indenture).

     However, a default under clause (4) or (5) will not constitute an Event of
Default until the Trustee or the Holders of 25% in principal amount of the
outstanding Notes

                                       63
<PAGE>   68

notify the Company of the default and the Company or such Guarantor does not
cure such default within the time specified after receipt of such notice.

     If an Event of Default (other than an Event of Default described in clause
(7) above with respect to the Company) occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the outstanding Notes may
declare the principal of and accrued but unpaid interest on all the Notes to be
due and payable. Upon such a declaration, such principal and interest shall be
due and payable immediately. If an Event of Default described in clause (7)
above with respect to the Company occurs and is continuing, the principal of and
interest on all the Notes will by that very fact become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holders. Under certain circumstances, the holders of a majority in principal
amount of the outstanding Notes may rescind any such acceleration and its
consequences with respect to the Notes and their consequences.

     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder of a Note may pursue
any remedy with respect to the Indenture or the Notes unless

     (1) such Holder has previously given the Trustee notice that an Event of
         Default is continuing,

     (2) Holders of at least 25% in principal amount of the outstanding Notes
         have requested the Trustee to pursue the remedy,

     (3) such Holders have offered the Trustee reasonable security or indemnity
         against any loss, liability or expense,

     (4) the Trustee has not complied with such request within 60 days after the
         receipt thereof and the offer of security or indemnity, and

     (5) the Holders of a majority in principal amount of the outstanding Notes
         have not given the Trustee a direction inconsistent with such request
         within such 60-day period.

     Subject to certain restrictions, the Holders of a majority in principal
amount of the outstanding Notes are given the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or of exercising any trust or power conferred on the Trustee. The Trustee,
however, may refuse to follow any direction that conflicts with law or the
Indenture or that the Trustee determines is unduly prejudicial to the rights of
any other Holder or that would involve the Trustee in personal liability.

     The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each Holder notice of the Default
within 90 days after it occurs. Except in the case of a Default in the payment
of principal of or interest on any Note, the Trustee may withhold notice if and
so long as a committee of its trust officers determines that withholding notice
is not opposed to the interest of the Holders. In addition, the Company is
required to deliver to the Trustee, within 120 days after the end of each fiscal
year, a certificate indicating whether the signers thereof know of any Default
that occurred during the previous year. The Company also is required to deliver
to the Trustee, within 30 days after the occurrence thereof, written notice of
any event which

                                       64
<PAGE>   69

would constitute certain Defaults, their status and what action the Company is
taking or proposes to take in respect thereof.

AMENDMENTS AND WAIVERS

     Subject to certain exceptions, the Indenture may be amended with the
consent of the Holders of a majority in principal amount of the Notes then
outstanding (including consents obtained in connection with a tender offer or
exchange for the Notes) and any past default or compliance with any provisions
may also be waived with the consent of the Holders of a majority in principal
amount of the Notes then outstanding. However, without the consent of each
Holder of an outstanding Note affected thereby, no amendment may, among other
things,

     (1) reduce the amount of Notes whose Holders must consent to an amendment,

     (2) reduce the rate of or change the time for payment of interest on any
         Note,

     (3) reduce the principal of or change the Stated Maturity of any Note,

     (4) reduce the amount payable upon the redemption of any Note or change the
         time at which any Note may be redeemed as described under " -- Optional
         Redemption,"

     (5) make any Note payable in money other than that stated in the Note,

     (6) impair the right of any Holder to receive payment of principal of and
         interest on such Holder's Notes on or after the due dates therefor or
         to institute suit for the enforcement of any payment on or with respect
         to such Holder's Notes,

     (7) make any change in the amendment provisions which require each Holder's
         consent or in the waiver provisions,

     (8) affect the ranking of the Notes in any material respect, or

     (9) release any Guarantor from any of its obligations under its Guarantee
         or the Indenture other than in accordance with the terms of the
         Indenture.

     Without the consent of any Holder, the Company and the Trustee may amend
the Indenture to cure any ambiguity, omission, defect or inconsistency, to
provide for the assumption by a successor Person of the obligations of the
Company and/or the Guarantors under the Indenture in accordance with "Certain
Covenants -- Merger and Consolidation," to provide for uncertificated Notes in
addition to or in place of certificated Notes (provided that the uncertificated
Notes are issued in registered form for purposes of Section 163(f) of the Code,
or in a manner such that the uncertificated Notes are described in Section
163(f)(2)(B) of the Code), to add guarantees with respect to the Notes, to
secure the Notes, to add to the covenants of the Company for the benefit of the
Holders or to surrender any right or power conferred upon the Company, to make
any change that does not adversely affect the rights of any Holder or to comply
with any requirement of the SEC in connection with the qualification of the
Indenture under the Trust Indenture Act.

     The consent of the Holders is not necessary under the Indenture to approve
the particular form of any proposed amendment. It is sufficient if such consent
approves the substance of the proposed amendment.

     After an amendment under the Indenture becomes effective, the Company is
required to mail to Holders a notice briefly describing such amendment. However,
the failure to give such notice to all Holders, or any defect therein, will not
impair or affect the validity of the amendment.

                                       65
<PAGE>   70

TRANSFER

     The Notes will be issued in registered form and will be transferable only
upon the surrender of the Notes being transferred for registration of transfer.
The Company may require payment of a sum sufficient to cover any tax, assessment
or other governmental charge payable in connection with certain transfers and
exchanges. Subject to the rules and regulations established by DTC, the Company
will not be required to transfer or exchange any Note selected for redemption or
to transfer or exchange any Note for a period of 15 days prior to a selection of
Notes to be redeemed.

DEFEASANCE

     The Company at any time may terminate all its obligations under the Notes
and the Indenture ("legal defeasance"), and the Guarantors may terminate their
obligations under the Guarantees, except for certain obligations, including
those respecting the defeasance trust and obligations to register the transfer
or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes
and to maintain a registrar and paying agent in respect of the Notes. The
Company at any time may terminate its obligations under "Change of Control" and
under the covenants described under "Certain Covenants" (other than the covenant
described under " -- Merger and Consolidation"), the operation of the cross
acceleration provision, the bankruptcy provisions with respect to Significant
Subsidiaries and the judgment default provision described under " -- Defaults"
above and the limitations contained in clauses (2) and (3) of the first
paragraph and clause (2) of the fourth paragraph under " -- Merger and
Consolidation" above ("covenant defeasance").

     The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because of
an Event of Default with respect thereto. If the Company exercises its covenant
defeasance option, payment of the Notes may not be accelerated because of an
Event of Default specified in clause (4), (6), (7) (with respect only to
Significant Subsidiaries) or (8) under "Defaults" above or because of the
failure of the Company to comply with clauses (2) and (3) of the first paragraph
and clause (2) of the fourth paragraph under "Certain Covenants -- Merger and
Consolidation" above.

     In order to exercise either defeasance option, the Company must irrevocably
deposit in trust (the "defeasance trust") with the Trustee U.S. dollars or U.S.
Government Obligations, or a combination thereof, for the payment of principal
of, premium, if any, and interest on the Notes to redemption or maturity, as the
case may be, and must comply with certain other conditions, including delivery
to the Trustee of an opinion of counsel to the effect that Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and defeasance and will be subject to federal income tax on the
same amounts and in the same manner and at the same times as would have been the
case if such deposit and defeasance had not occurred (and, in the case of legal
defeasance only, such opinion of counsel must be based on a ruling of the
Internal Revenue Service or other change in applicable Federal income tax law).

SATISFACTION AND DISCHARGE

     The Indenture will cease to be of further effect (except as to surviving
rights of registration of transfer or exchange of the Notes, as expressly
provided for in the Indenture) as to all outstanding Notes when:

     (1) either (a) all the Notes theretofore authenticated and delivered
         (except lost, stolen or destroyed Notes which have been replaced or
         paid) have been delivered

                                       66
<PAGE>   71

         to the Trustee for cancellation or (b) all Notes not theretofore
         delivered to the Trustee for cancellation have become due and payable
         or shall become due and payable within one year and the Company has
         irrevocably deposited or caused to be deposited with the Trustee an
         amount in U.S. dollars sufficient to pay and discharge the entire
         indebtedness on the Notes not theretofore delivered to the Trustee for
         cancellation, for the principal of, premium, if any, and interest to
         the date of deposit;

     (2) the Company has paid or caused to be paid all other sums payable under
         the Indenture by the Company; and

     (3) the Company has delivered to the Trustee an officers' certificate and
         an opinion of counsel each stating that all conditions precedent under
         the Indenture relating to the satisfaction and discharge of the
         Indenture have been complied with.

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     The Indenture provides that no recourse for the payment of the principal
of, premium, if any, or interest on any of the Notes or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture, or in any of
the Notes or because of the creation of any Indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer, director, employee
or controlling person of the Company or any successor Person thereof. Each
Holder, by accepting the Notes, waives and releases all such liability. Such
waiver may not be effective to waive liabilities under the federal securities
laws and it is the view of the SEC that such waiver is against public policy.

CONCERNING THE TRUSTEE

     Bankers Trust Company is the Trustee under the Indenture and has been
appointed by the Company as Registrar and Paying Agent with regard to the Notes.

     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee is permitted to engage in other
transactions; provided, however, if it acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue or resign.

     The Holders of a majority in principal amount of the outstanding Notes have
the right to direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee, subject to certain exceptions.
The Indenture provides that if an Event of Default occurs (and is not cured),
the Trustee will be required, in the exercise of its power, to use the degree of
care of a prudent man in the conduct of his own affairs. Subject to such
provisions, the Trustee is under no obligation to exercise any of its rights or
powers under the Indenture at the request of any Holder of Notes, unless such
Holder shall have offered to the Trustee security and indemnity satisfactory to
it against any loss, liability or expense and then only to the extent required
by the terms of the Indenture.

GOVERNING LAW

     The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York.

                                       67

         effect thereto as if such Investment or acquisition occurred on the
         first day of such period; and

     (4) if since the beginning of such period any Person (that subsequently
         became a Restricted Subsidiary or was merged with or into the Company

the average rate in effect during the period had been the applicable rate for
the entire period (taking into account any fixed rate established by an Interest
Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement
has a remaining term in excess of 12 months, in which case such fixed rate shall
be used).

                           INCOME TAX CONSIDERATIONS

EXCHANGE OF NOTES

     The exchange of outstanding notes for exchange notes in the exchange offer
will not constitute a taxable event to holders. Consequently, no gain or loss
will be recognized by a holder upon receipt of an exchange note, the holding
period of the exchange note will include the holding period of the outstanding
note and the basis of the exchange note will be the same as the basis of the
outstanding note immediately before the exchange.

     IN ANY EVENT, PERSONS CONSIDERING THE EXCHANGE OF OUTSTANDING NOTES FOR
EXCHANGE NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE UNITED
STATES FEDERAL INCOME TAX CONSEQUENCES IN LIGHT OF THEIR PARTICULAR SITUATIONS
AS WELL AS ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING
JURISDICTION.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives exchange notes for its own account
pursuant to the exchange offer must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange notes. This
prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of exchange notes received in
exchange for outstanding notes where such outstanding notes were acquired as a
result of market-making activities or other trading activities. We have agreed
that, for a period of 180 days after the consummation of the exchange offer, we
will make this prospectus, as amended or supplemented, available to any
broker-dealer for use in connection with any such resale.

     We will not receive any proceeds from any sale of exchange notes by
broker-dealers. Exchange notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the exchange notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such exchange notes. Any broker-dealer
that resells exchange notes that were received by it for its own account
pursuant to the exchange offer and any broker or dealer that participates in a
distribution of such exchange notes may be deemed to be an "underwriter" within
the meaning of the Securities Act and any profit on any such resale of exchange
notes and any commission or concessions received by any such persons may be
deemed to be underwriting compensation under the Securities Act. The letter of
transmittal states that, by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     For a period of 180 days after the consummation of the exchange offer we
will promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay all expenses incident to the
exchange offer (including the expenses of one counsel for the holders of the
notes) other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Financial statement note disclosures, normally included in financial
statements prepared in conformity with generally accepted accounting principles,
have been omitted in this Form 10-Q pursuant to the Rules and Regulations of the
Securities and Exchange Commission. However, in the opinion of the Company, the
disclosures contained in this Form 10-Q are adequate to make the information
presented not misleading when read in conjunction with the notes to consolidated
financial statements included in the Company's Annual Report on Form 10-K for
the Year Ended December 31, 1998, as filed with the Securities and Exchange
Commission on March 29, 1999.

     In the opinion of the Company, the accompanying unaudited consolidated
financial statements reflect all adjustments (consisting of only normal
recurring adjustments) necessary to present fairly the Unaudited Consolidated
Balance Sheet at March 31, 1999, the Unaudited Consolidated Statement of
Operations for the three months ended March 31, 1998, and 1999, the Unaudited
Consolidated Statement of Changes in Stockholders' Equity for the three months
ended March 31, 1999, and the Unaudited Consolidated Statement of Cash Flows for
the three months ended March 31, 1998, and 1999. Operating results for the three
months ended March 31, 1999 are not necessarily indicative of the results that
may be expected for the year ended December 31, 1999.

2.  RECEIVABLES

     As of December 31, 1998 and March 31, 1999, unbilled receivables were
$209,334,000 and $214,941,000, respectively.

3.  EARNINGS PER SHARE

     Basic earnings per share is computed using the weighted average number of
common shares outstanding during the period. Diluted earnings per share is
computed in the same manner as basic earnings per share but adds the number of
additional common shares that would have been outstanding for the period if the
dilutive potential common shares had been issued. The only difference between
the number of weighted average shares used in the basic and diluted calculation
for all years is stock options and stock warrants granted by the Company using
the "treasury stock" method.

4.  ACQUISITION

     On April 1, 1998 the Company acquired all of the outstanding capital stock
of Value Health, Inc. and Managed Prescriptions Network, Inc. (collectively, the
"Acquired Entities") from Columbia/HCA Healthcare Corporation ("Columbia") for
approximately $460 million in cash (which includes transactions costs and
executive management severance costs of approximately $15 million),
approximately $360 million of which was obtained through a five-year bank credit
facility (see Note 4) and the remainder from the Company's cash balances and
short-term investments. At closing, the Acquired Entities owned various
subsidiaries that now or formerly conducted a PBM business, commonly known as
"ValueRx."

     The acquisition has been accounted for using the purchase method of
accounting and the results of operations of the Acquired Entities have been
included in the consolidated

financial statements and PBM segment since April 1, 1998. The purchase price has
been allocated based on the estimated fair values of net assets acquired at the
date of the acquisition. The excess of purchase price over tangible net assets
acquired has been allocated to other intangible assets consisting of customer
contracts and non-compete agreements in the amount of $57,653,000 which are
being amortized using the straight-line method over the estimated useful lives
of 2 to 20 years and are included in other assets, and goodwill in the amount of
$278,113,000 which is being amortized using the straight-line method over the
estimated useful life of 30 years. In conjunction with the acquisition, the
Acquired Entities and their subsidiaries retained the following liabilities:

5.  FINANCING

     On April 1, 1998, the Company executed a $440 million credit facility with
a bank syndicate led by Bankers Trust Company, consisting of a $360 million term
loan facility and an $80 million revolving loan facility. The credit facility
expires on April 15, 2003 and is guaranteed by the Company's domestic
subsidiaries other than Practice Patterns Science, Inc. ("PPS"), and Great
Plains Reinsurance Company ("Great Plains") and secured by pledges of 100% (or,
in the case of foreign subsidiaries, 65%) of the capital stock of the Company's
subsidiaries other than PPS and Great Plains. The provisions of this term loan
require quarterly interest payments and, beginning in April 1999, semi-annual
principal payments. The interest rate is based on a spread ("Credit Rate
Spread") over several London Interbank Offered Rates ("LIBOR") or base rate
options, depending upon the Company's ratio of earnings before interest, taxes,
depreciation and amortization

                                       F-8
<PAGE>   99
                             EXPRESS SCRIPTS, INC.

      NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

("EBITDA") to debt ("Leverage Ratio"). At March 31, 1999, the interest rate was
5.84375%, representing a credit rate spread of 0.75% over the three-month LIBOR
rate. The credit facility contains covenants that limit the indebtedness the
Company may incur and the amount of annual capital expenditures. The covenants
also establish a minimum interest coverage ratio, a maximum leverage ratio, and
a minimum consolidated net worth. At March 31, 1999, the Company was in
compliance with all covenants. In addition, the Company is required to pay an
annual fee depending on the leverage ratio, payable in quarterly installments,
on the unused portion of the revolving loan. The commitment fee was 22.5 basis
points at March 31, 1999. There were no borrowings at March 31, 1999 under the
revolving loan facility. The carrying amount of the Company's term loan facility
approximates fair value.

     In conjunction with the Company's policy to manage interest rate risk, the
Company entered into an interest rate swap agreement ("swap") with The First
National Bank of Chicago, a subsidiary of Bank One Corporation, on April 3,
1998. At March 31, 1999, the swap had a notional principal amount of $360
million. Under the terms of the swap, the Company agrees to receive a floating
rate of interest on the amount of the term loan facility based on a three-month
LIBOR rate in exchange for payment of a fixed rate of interest of 5.88% per
annum. The notional principal amount of the swap amortizes in equal amounts with
the principal balance of the term loan facility. As a result, the Company has,
in effect, converted its variable rate term debt to fixed rate debt at 5.88% per
annum for the entire term of the term loan facility, plus the Credit Rate
Spread.

6.  RESTRUCTURING

     During the second quarter of 1998, the Company recorded a pre-tax
restructuring charge of $1,651,000 ($1,002,000 after taxes or $0.03 per basic
and diluted earnings per share) associated with the Company closing the non-PBM
service operations of its wholly-owned subsidiary, PhyNet, Inc., and
transferring certain functions of its Express Scripts Vision Corporation to
another vision care provider.

</TABLE>

     The restructuring charge includes tangible assets to be disposed of being
written down to their net realizable value, less cost of disposal. Management
expects recovery to approximate its cost of disposal. Considerable management
judgment is necessary to estimate fair value; accordingly, actual results could
vary from such estimates. The Company anticipates completing the remainder of
the restructuring actions by the end of the third quarter of 1999.

7.  SEGMENT REPORTING

     The Company is organized on the basis of services offered and has
determined that it has two reportable segments: PBM services and non-PBM
services. The Company manages the pharmacy benefit within an opening segment
which encompasses a fully-integrated PBM service. The remaining three operating
service lines (IVTx, Specialty Distribution and Vision) have been aggregated
into a non-PBM reporting segment.

     The following table presents information about the reportable segments for
the three months ended March 31:

8.  SUBSEQUENT EVENTS

     On April 1, 1999 the Company completed its acquisition of Diversified
Pharmaceutical Services, Inc. and Diversified Pharmaceutical Services (Puerto
Rico) Inc. (collectively, "DPS"), from SmithKline Beecham Corporation and
SmithKline Beecham InterCredit BV (collectively, "SB") for approximately $700
million in cash, such amount being subject to adjustment based upon the amount
of working capital of DPS at closing. The acquisition will be accounted for
under the purchase method of accounting. The Company will file an Internal
Revenue Code sec.338(h)(10) election, making amortization expense of certain
intangible assets, including goodwill, tax deductible.

     The Company used approximately $48 million of its own cash and financed the
remainder of the purchase price and related acquisition costs through a $1.05
billion credit facility with a bank syndicate led by Credit Suisse First Boston
and Bankers Trust Company, and a $150 million senior subordinated bridge credit
facility from Credit Suisse First Boston and Bankers Trust Company. The Company
also used a portion of the proceeds from the $1.05 billion credit facility to
retire the $360 million principal balance outstanding on its $440 million credit
facility (see Note 4). As a result of the retirement of the $360 million balance
outstanding on its $440 million credit facility, the Company will write-off the
remaining deferred financing fees at March 31, 1999 of $3,250,000, or
approximately $1,950,000 net of tax, as an extraordinary item during the second
quarter of 1999.

     The $1.05 billion credit facility consists of a $300 million revolving
facility, a $285 million term facility ("Term A"), and a $465 million term
facility ("Term B"). The revolving facility and the Term A facility are for a
period of six years. The Term B facility is for a period of eight years. The
provisions of this loan require quarterly interest payments and, beginning in
March 2000, annual principal payments. The interest rate is

based on a spread (the "Base Rate Margin") over several LIBOR or base rate
options, depending upon the Company's ratio of debt to EBITDA. However, the
initial base rate margin is fixed at 275 basis points for the revolving facility
and Term A facility and 350 basis points for the Term B facility for the first
two quarters. The credit facility contains covenants that limit the indebtedness
the Company may incur and the amount of annual capital expenditures. The
covenants also establish a minimum interest coverage ratio, a maximum leverage
ratio, and a minimum fixed charge coverage ratio. In addition, the Company is
required to pay an annual fee of 50 basis points, payable in quarterly
installments, on the unused portion of the revolving facility.

     The following represents the schedule of current maturities for the Term A
and Term B facilities (in thousands):

     On March 24, 1999, the Company's Board of Directors adopted, and on May 26,
1999, the Company's stockholders approved, an amendment to the Company's Amended
and Restated 1994 Stock Option Plan to, among other things, increase the number
of shares reserved for issuance under this plan. A total of 2,920,000 shares of
the Company's Class A common stock are currently reserved for issuance under
this plan, and said amount will automatically increase on January 1 of each
year, to and including January 1, 2004, by an amount equal to 1% of the
aggregate number of then outstanding shares of the Company's Class A and Class B
common stock.

     On May 26, 1999, the Company's stockholders approved an amendment to the
Company's certificate of incorporation to increase the number of authorized
shares of Class A common stock from 75 million to 150 million and the number of
authorized shares of Class B common stock from 22 million to 31 million.

     On June 18, 1999, the Company learned that it is named as a defendant in
Allcare Health Management Systems, Inc. v. Cerner Corporation, et al. No.
499-CV-0464-Y (N.D. TX). Plaintiff commenced this action on or about June 16,
1999, alleging infringement of a patent owned by Plaintiff on a "Wellness Health
Management System" by the Company and its wholly-owned subsidiary Diversified
Pharmaceutical Services, Inc. and ten other unrelated entities. At this stage of
the litigation, neither the merits of Plaintiff's claim nor the potential
liability associated with it, if any, can be ascertained.

     On June 18, 1999, SB transferred ownership of Diversified Prescription
Delivery L.L.C. ("DPD"), to the Company, pursuant to the Company's stock
purchase agreement

with SB for the acquisition of DPS. The acquisition will be accounted for under
the purchase method of accounting.


     In June 1999, the Company completed its equity offering of 5,175,000 shares
of its Class A common stock, which includes the underwriters' over-allotments.
The Company received net proceeds of $300,393,000. The Company also completed
the sale of $250 million of 9 5/8% Senior Notes due 2009 through a private
placement, receiving net proceeds of $243,502,000. The Company used the net
proceeds from the offerings, along with approximately $25 million of its own
cash, to repay the $150 million senior subordinated bridge credit facility plus
accrued interest and $414,770,000 of the Term B facility plus accrued interest.
As a result of the retirement of a portion of the Term B facility, the Company
will write-off $7,491,000, or, approximately $4,495,000 net of tax, in deferred
financing fees as an extraordinary item during the second quarter of 1999. In
July 1999, the Company retired the Term B facility by paying the amounts
outstanding of $50,230,000 through use of its cash. As a result, we will record
an extraordinary change during the third quarter of 1999 for the write-off of
the remaining deferred financing fees in the amount of $907,000, or
approximately $557,000 net of tax.


     The 9 5/8% Senior Notes are due June 15, 2009 and require semi-annual
interest payments beginning December 15, 1999. The Senior Notes are guaranteed
by the Company's domestic subsidiaries other than Practice Patterns Science,
Inc., Great Plains Reinsurance Company, ValueRx of Michigan, Inc., Diversified
NY IPA, Inc. and Diversified Pharmaceutical Services (Puerto Rico) Inc. The
following is a summary of financial position and results of operations of the

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Express Scripts, Inc.

     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of changes in stockholders' equity and of
cash flows present fairly, in all material respects, the financial position of
Express Scripts, Inc. and its subsidiaries at December 31, 1998 and 1997, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION AND OPERATIONS.  Express Scripts, Inc. ("the Company") is a
leading specialty managed care company and (subsequent to its acquisition of
Value Health, Inc. and Managed Prescription Network, Inc. on April 1, 1998, see
Note 2) is the largest full-service pharmacy benefit management ("PBM") company
independent of pharmaceutical manufacturer ownership and drug store ownership in
North America. The Company provides healthcare management and administration
services on behalf of thousands of clients that include health maintenance
organizations, health insurers, third-party administrators, employers and
union-sponsored benefit plans. The Company's fully-integrated PBM services
include network claims processing, mail pharmacy services, benefit design
consultation, drug utilization review, formulary management, disease management,
medical and drug data analysis services, medical information management
services, which include provider profiling and outcome assessments through its
majority-owned Practice Patterns Science, Inc. ("PPS") subsidiary, and informed
decision counseling services through its Express Health LineSM division. The
Company also provides non-PBM services which include infusion therapy services
through its wholly-owned subsidiary IVTx, Inc. ("IVTx"), distribution services
through its Specialty Distribution division, and, prior to September 1, 1998,
provided managed vision care programs through its wholly-owned subsidiary
Express Scripts Vision Corporation ("Vision").

     In March 1992, the Company, originally incorporated in Missouri in 1986,
was reincorporated in Delaware and issued an aggregate of 21,000,000 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 Insurance Company ("NYL"). 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 5,980,000 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 11).

     BASIS OF PRESENTATION.  The consolidated financial statements include the
accounts of the Company and all wholly-owned and majority-owned subsidiaries.
All significant intercompany accounts and transactions have been eliminated.
Certain amounts in prior years have been reclassified to conform with 1998
classifications. The preparation of the consolidated 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.

     CASH AND CASH EQUIVALENTS.  Cash and cash equivalents include cash on hand
and temporary investments in money market funds.

     SHORT-TERM INVESTMENTS.  Short-term investments consisted of debt
securities with a maturity of less than one year that the Company had the
positive intent and ability to hold to maturity and are reported at amortized
cost.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     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.  During 1997, the Company early adopted
Statement of Position No. 98-1 ("SOP 98-1"), Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use. SOP 98-1 requires the
capitalization of certain costs associated with computer software developed or
obtained for internal use. Given the limited software developed or obtained for
internal use in 1997, adoption had virtually no effect on the Company's
Consolidated Statement of Operations or its financial position. However, the
impact of SOP 98-1 on an ongoing basis will be determined by the magnitude of
computer software developed or obtained for internal use. Research and
development expenditures relating to the development of software to be marketed
to clients, or to be used for internal purposes, are charged to expense until
technological feasibility is established. Thereafter, the remaining software
production costs up to the date of general release to customers, or to the date
placed into production, are capitalized and included as Property and Equipment.
During 1996, 1997 and 1998, $1,898,000, $1,982,000 and $10,244,000 in software
development costs were capitalized, respectively. Capitalized software
development costs amounted to $5,269,000 and $27,516,000 at December 31, 1997
and 1998, respectively. Amortization of the capitalized amounts commences on the
date of general release to customers, or the date placed into production, 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
in 1996, 1997 and 1998 was $136,000, $622,000 and $1,968,000, respectively.

     GOODWILL.  Goodwill is amortized on a straight-line basis over periods from
15 to 30 years. The amount reported is net of accumulated amortization of
$251,000 and $8,114,000 at December 31, 1997 and 1998, respectively. The Company
periodically evaluates the carrying value of goodwill for impairment. The
evaluation of impairment is based on expected future operating cash flows on an
undiscounted basis for the operations to which goodwill relates. Impairment
losses, if any, would be determined based on the present value of the cash flows
using discount rates that reflect the inherent risk of the underlying business.
In the opinion of management, no such impairment existed at December 31, 1997 or
1998. Amortization expense, included in selling, general and administrative
expenses, was $42,000, $42,000 and $7,863,000 for the years ended December 31,
1996, 1997 and 1998, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     OTHER INTANGIBLE ASSETS.  Other intangible assets (included in other
assets) consist of customer contracts, non-compete agreements and deferred
financing fees and are amortized on a straight-line basis over periods from 2 to
20 years. Amortization expense for customer contracts and non-compete
agreements, included in selling, general and administrative expenses, and for
deferred financing fees, included in interest expense, was $4,320,000 and
$609,000, respectively, for the year ended December 31, 1998.

     CONTRACTUAL AGREEMENTS.  The Company has entered into corporate alliances
with certain of its clients whereby shares of the Company's Class A Common Stock
were awarded as advance discounts to the clients. The Company accounts for these
agreements as follows:

          PRIOR TO DECEMBER 15, 1995 -- 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.

          BETWEEN DECEMBER 15, 1995 AND NOVEMBER 20, 1997 -- For agreements
     entered into between these dates, the Company utilizes the provisions of
     Financial Accounting Standards Board Statement 123 "Accounting for
     Stock-Based Compensations" ("FAS 123") which 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 or to be issued under the
     Premier and Manulife alliances based on fair value at the date the
     agreement was consummated.

          SUBSEQUENT TO NOVEMBER 20, 1997 -- In November 1997, the Emerging
     Issues Task Force reached a consensus that the value of equity instruments
     issued for consideration other than employee services should be initially
     determined on the date on which a "firm commitment" for performance first
     exists by the provider of goods or services. Firm commitment is defined as
     a commitment pursuant to which performance by a provider of goods or
     services is probable because of sufficiently large disincentives for
     nonperformance. The consensus must be applied for all new arrangements and
     modifications of existing arrangements entered into from November 20, 1997.
     The consensus only addresses the date upon which fair value is determined
     and does not change the accounting based upon fair value as prescribed by
     FAS 123. No such arrangements have been entered into by the Company
     subsequent to November 20, 1997.

     Shares issued on the effective date of the contractual agreement are
     considered outstanding and included in basic and diluted earnings per share
     computations when issued. Shares issuable upon the satisfaction of certain
     conditions are considered outstanding and included in basic and dilutive
     earnings per share computation when all necessary conditions have been
     satisfied by the end of the period. If all necessary conditions have not
     been satisfied by the end of the period, the number of shares included in
     the dilutive earnings per share computation is based on the number of

                                      F-22
<PAGE>   113
                             EXPRESS SCRIPTS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     shares, if any, that would be issuable if the end of the reporting period
     were the end of the contingency period and if the result would be dilutive.
     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.

     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. Impairment losses, if any, would be determined
based on the present value of the cash flows using discount rates that reflect
the inherent risk of the underlying business. In the opinion of management, no
such impairment existed as of December 31, 1997 or 1998, except for the
write-down of the long-lived assets of Express Scripts Vision Corporation (see
Note 7).

     DERIVATIVE FINANCIAL INSTRUMENTS.  The Company has entered into an interest
rate swap agreement in order to manage exposure to interest rate risk. The
Company does not hold or issue derivative financial instruments for trading
purposes. The interest rate swap is designated as a hedge of the Company's
variable interest rate payments. Amounts received or paid are accrued as
interest receivable or payable and as interest income or expense. The fair value
of interest rate swap agreements is based on market prices. The fair value
represents the estimated amount the Company would receive/pay to terminate the
agreements taking into consideration current interest rates.

     In June 1998, the Financial Accounting Standards Board ("the FASB") issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("FAS 133"). The Statement requires all
derivatives be recognized as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. In addition, the
Statement specifies the accounting for changes in the fair value of a derivative
based on the intended use of the derivative and the resulting designation. FAS
133 is effective for all fiscal quarters of fiscal years beginning after June
15, 1999 and will be applicable to the Company's first quarter of fiscal year
2000. The Company's present interest rate swap (see Note 6) would be considered
a cash flow hedge. Accordingly, the change in the fair value of the swap would
be reported on the balance sheet as an asset or liability. The corresponding
unrealized gain or loss representing the effective portion of the hedge will be
initially recognized in stockholders' equity and other comprehensive income, and
subsequently any changes in unrealized gain or loss from the initial measurement
date will be recognized in earnings concurrent with the interest expense on the
Company's underlying variable rate debt. If the Company had adopted FAS 133 as
of December 31, 1998, the Company would record the unrealized loss of $7,209,000
as a liability and reduction in stockholder's equity and other comprehensive
income.

     FAIR VALUE OF FINANCIAL INSTRUMENTS.  The carrying value of cash and cash
equivalents, short-term investments, accounts receivable and accounts payable
approximated fair values due to the short-term maturities of these instruments.
The fair value, which approximates the carrying value, of the Company's term
loan facility was estimated using either quoted

                                      F-23
<PAGE>   114
                             EXPRESS SCRIPTS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

market prices or the current rates offered to the Company for debt with similar
maturity. The fair value of the swap ($7,209,000 liability at December 31, 1998)
was based on quoted market price, which reflects the present value of the
difference between estimated future fixed rate payments and future variable rate
receipts.

     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 dispenses
pharmaceuticals to members of health benefit plans sponsored by the Company's
clients or 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 ingredient costs or payments to these pharmacy providers in cost
of revenues. If the Company is only administering the plan sponsors' network
pharmacy contracts, or where the Company dispenses pharmaceuticals supplied by
one of the Company's clients, the Company records only the administrative or
dispensing fees derived from the Company's contracts with the plan sponsors as
net revenue.

     Client revenue is recognized based upon actual scripts adjudicated and
therefore requires no estimation. Amounts remain unbilled for no more than 30
days based upon the contractual billing schedule agreed with the client. At
December 31, 1997 and 1998, unbilled receivables were $96,644,000 and
$209,334,000, respectively.

     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. The Company estimates fees
receivable from pharmaceutical manufacturers on a quarterly basis converting
total prescriptions dispensed to estimated rebatable scripts (i.e., those
prescriptions with respect to which the Company is contractually entitled to
submit claims for rebates) multiplied by the contractually agreed manufacturer
rebate amount. Estimated fees receivable from pharmaceutical manufacturers are
recorded when determined by management to be realizable, and realization is not
dependent upon future pharmaceutical sales. Estimates are revised once the
actual rebatable scripts are calculated and rebates are billed to the
manufacturer.

     INCOME TAXES.  Deferred tax 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.

     EARNINGS PER SHARE.  Basic earnings per share is computed using the
weighted average number of common shares outstanding during the period. Diluted
earnings per share is computed in the same manner as basic earnings per share
but adds the number of additional common shares that would have been outstanding
for the period if the dilutive potential common shares had been issued. The only
difference between the number of weighted average shares used in the basic and
diluted calculation for all years is stock options and stock warrants granted by
the Company using the "treasury stock" method, amounting to 540,000, 409,000 and
593,000 in 1996, 1997 and 1998, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     FOREIGN CURRENCY TRANSLATION.  The financial statements of ESI Canada, Inc.
are translated into U.S. Dollars using the exchange rate at each balance sheet
date for assets and liabilities and a weighted average exchange rate for each
period for revenues, expenses, gains and losses. The functional currency for ESI
Canada, Inc. is the local currency and translation adjustments are recorded
within the other comprehensive income component of stockholders' equity.

     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, FAS 123 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
12).

     COMPREHENSIVE INCOME.  During 1998, Statement of Financial Accounting
Standards No. 130 ("FAS 130"), "Reporting Comprehensive Income," became
effective for the Company. FAS 130 requires noncash changes in stockholders'
equity be combined with net income and reported in a new financial statement
category entitled "comprehensive income." Other than net income, the only
component of comprehensive income for the Company is the change in the foreign
currency translation adjustment. The Company has displayed comprehensive income
within the Statement of Changes in Stockholders' Equity.

     SEGMENT REPORTING.  In June 1997, the FASB issued Statement of Financial
Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and
Related Information" ("FAS 131"). FAS 131 requires that the Company report
certain information, if specific requirements are met, about operating segments
of the Company including information about services, geographic areas of
operation and major customers. The information is to be derived from the
management approach which designates the internal organization that is used by
management for making operating decisions and assessing performance as the
source of the Company's reportable segments. Adoption of FAS 131 did not affect
the Company's results of operations or its financial position but did affect the
disclosure of segment information (see Note 13).

2.  ACQUISITION

     On April 1, 1998 the Company acquired all of the outstanding capital stock
of Value Health, Inc. and Managed Prescriptions Network, Inc. (collectively, the
"Acquired Entities") from Columbia/HCA Healthcare Corporation ("Columbia") for
approximately $460 million in cash (which includes transactions costs and
executive management severance costs of approximately $15 million),
approximately $360 million of which was obtained through a five-year bank credit
facility (see Note 6) and the remainder from the Company's cash balances and
short term investments. At closing, the Acquired Entities

owned various subsidiaries that now or formerly conducted a PBM business,
commonly known as "ValueRx".

     The acquisition has been accounted for using the purchase method of
accounting and the results of operations of the Acquired Entities have been
included in the consolidated financial statements and PBM segment since April 1,
1998. The purchase price has been preliminarily allocated based on the estimated
fair values of net assets acquired at the date of the acquisition. The excess of
purchase price over tangible net assets acquired was originally allocated to
other intangible assets consisting of customer contracts and non-compete
agreements in the amount of $57,653,000 which are being amortized using the
straight-line method over the estimated useful lives of 2 to 20 years and are
included in other assets, and goodwill in the amount of $289,863,000 which is
being amortized using the straight-line method over the estimated useful life of
30 years. In conjunction with the acquisition, the Acquired Entities and their
subsidiaries retained the following liabilities:

3.  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 an 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 4,500,000 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.

     In accordance with the terms of the agreement, the Company issued 454,546
shares of Class A Stock to Premier in May, 1996. The shares were valued at
$11,250,000 using the Company's closing stock price on December 31, 1995, the
date the agreement was consummated, and are being amortized over the remaining
term of the agreement. Amortization expense in 1996, 1997 and 1998 was $776,000,
$1,164,000 and $1,164,000, respectively. No additional shares have been earned
by Premier through December 31, 1998.

     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, the Company is 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 474,000 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 has
been issued since inception.

     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
237,000 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 50,000 shares of Class A Common Stock as an
advance discount to Coventry in a private placement. These shares were valued at
$13.69 per share, the split-adjusted 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 were being amortized over a six-year period. However, due to
Coventry extending the agreement for only two years, as discussed below, instead
of three years, the estimated useful life of the shares issued has been reduced
to five years. Amortization expense was $114,000, $114,000 and $171,000 for each
of the years ended December 31, 1996, 1997 and 1998, respectively. 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.

     Effective January 1, 1998, Coventry renewed the agreement for a two-year
term through December 31, 1999. As part of the agreement, the Company issued
warrants as an advance discount to purchase an additional 50,000 shares of the
Company's Class A Common Stock, exercisable at 90% of the market value at the
time of renewal. During 1998, the Company expensed the advance discount which
represented 10% of the market value.

     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 February
1997, PacifiCare Health Systems, Inc. ("PacifiCare") completed the acquisition
of FHP. As a result of the merger, PacifiCare informed the Company that it would
not enter into a long-term extension of the agreement and reached an agreement
with the Company to phase-out membership starting in July 1997 and continued
through March 1998.

     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 400,000 shares of its
Class A Common Stock as advance discounts to FHP in a private placement. These
shares were valued at $4.13 per share, the split-adjusted 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 was amortized over a five-year period ending in 1997. No amortization
expense was recorded in 1998. Amortization expense was $165,000 in 1996 and
$990,000 in 1997.

4.  RELATED PARTY TRANSACTIONS

     The Company had 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.
Effective July 15, 1998, NYL consummated the sale of NYLCare to Aetna U.S.
Healthcare, Inc., an unrelated party. Therefore, related party amounts for 1998
represent only the period in which NYL owned NYLCare. Transactions subsequent to
July 15, 1998 have been included in unrelated parties.

</TABLE>

     Prior to July 15, 1998, the Company was the exclusive provider of pharmacy
benefit management services to NYLCare's managed healthcare subsidiaries,
subject to certain exceptions. The Company's agreement with NYLCare provided
that fees from drug manufacturers whose products are used in the Company's
formularies related to NYLCare subsidiaries was allocated 100% to the Company up
to $400,000 and 75% to NYLCare and 25% to the Company thereafter. The Company
was also the non-exclusive provider of pharmacy benefit management services to
New York Life and Health Insurance Company ("NYLHIC"), a subsidiary of NYLCare.
In 1996 fees from drug manufacturers with respect to this business were
allocated 100% to the Company. Effective January 1, 1997, the Company shared
such fees with NYLHIC on a fixed per script amount which approximates 40% of the
total of such fees.

     Such fees allocated to NYLCare and NYLHIC were $7,636,000, $11,690,000 and
$7,257,000 in 1996, 1997 and 1998, respectively, and $3,064,000 in 1996,
$5,803,000 in 1997 and $2,307,000 in 1998 were allocated to the Company and have
been classified in the accompanying consolidated statement of operations as a
reduction of cost of revenues.

     As discussed in Note 3, the Company has entered into a ten year corporate
alliance with Premier. Richard Norling is the Chief Operating Officer of Premier
and a member of the Company's Board of Directors. No consideration, monetary or
otherwise, has been exchanged between the Company and Premier between the period
September 1997 and December 1998 (the period during which Premier and the
Company are related parties). The Company may be required to issue additional
shares of its Class A Common Stock to Premier as discussed in Note 3.

     Premier is required to promote the Company as the preferred PBM provider to
healthcare entities, plans and facilities which participate in Premier's
purchasing programs. However, all contractual arrangements to provide services
are made directly between the Company and these entities, at varying terms and
independent of any Premier involvement. Therefore, the associated revenues
earned and expenses incurred by the Company are not deemed to be related party
transactions. During 1998, the net revenues that the Company derived from
services provided to the healthcare entities participating in Premier's
purchasing programs was $78,539,000.

6.  FINANCING

     On April 1, 1998, the Company executed a $440 million credit facility with
a bank syndicate led by Bankers Trust Company, consisting of a $360 million term
loan facility and an $80 million revolving loan facility. The credit facility
expires on April 15, 2003 and is guaranteed by the Company's domestic
subsidiaries other than Practice Patterns Science, Inc. ("PPS"), and Great
Plains Reinsurance Company ("Great Plains") and secured by pledges of 100% (or,
in the case of foreign subsidiaries, 65%) of the capital stock of the Company's
subsidiaries other than PPS and Great Plains. The provisions of this loan
require quarterly interest payments and, beginning in April 1999, semi-annual
principal payments. The interest rate is based on a spread ("Credit Rate
Spread") over several London Interbank Offered Rates ("LIBOR") or base rate
options, depending upon the Company's ratio of earnings before interest, taxes,
depreciation and amortization to debt ("Leverage Ratio"). At December 31, 1998,
the interest rate was 6.0625%, representing a credit rate spread of 0.75% over
the three month LIBOR rate. The credit facility contains covenants that limit
the indebtedness the Company may incur and the amount of annual capital
expenditures. The covenants also establish a minimum interest coverage ratio, a
maximum leverage ratio, and a minimum consolidated net worth. At December 31,
1998, the Company was in compliance with all covenants. In addition, the Company
is required to pay an annual fee depending on the leverage ratio, payable in
quarterly installments, on the unused portion of the revolving loan. The
commitment fee was 22.5 basis points at December 31, 1998. There were no
borrowings at December 31, 1998 under the revolving loan facility. The carrying
amount of the Company's term loan facility approximates fair value.

     In conjunction with the credit facility and as part of the Company's policy
to manage interest rate risk, the Company entered into an interest rate swap
agreement ("swap") with The First National Bank of Chicago, a subsidiary of Bank
One Corporation, on

                                      F-30

                             EXPRESS SCRIPTS, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

April 3, 1998. At December 31, 1998, the swap had a notional principal amount of
$360 million. Under the terms of the swap, the Company agrees to receive a
floating rate of interest on the amount of the term loan facility based on a
three month LIBOR rate in exchange for payment of a fixed rate of interest of
5.88% per annum. The notional principal amount of the swap amortizes in equal
amounts with the principal balance of the term loan facility. As a result, the
Company has, in effect, converted its variable rate term debt to fixed rate debt
at 5.88% per annum for the entire term of the term loan facility, plus the
Credit Rate Spread.

     The following represents the schedule of current maturities for the term
loan facility (amounts in thousands):

     Prior to April 1, 1998, the Company maintained a $25,000,000 unsecured line
of credit with the Mercantile Bank National Association which was terminated
upon the consummation of the Bankers' Trust credit facility. Additionally, the
Company allowed another line of credit in the amount of $25 million to lapse on
October 31, 1997. Terms of the agreements were as follows: interest was 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 the agreements on any unused portion
were charged at 10 basis points per year. At December 31, 1997, the Company had
no outstanding borrowings under this agreement, nor did it borrow any amounts
under these agreements during 1997.

7.  CORPORATE RESTRUCTURING

     During 1998, the Company recorded a pre-tax restructuring charge of
$1,651,000 ($1,002,000 after taxes or $0.03 per basic earnings per share and
$0.03 per dilutive earnings per share) associated with the Company closing the
non-PBM service operations of its wholly-owned subsidiary, PhyNet, Inc., and
transferring certain functions of its Express Scripts Vision Corporation to
another vision care provider.

     The restructuring charge includes tangible assets to be disposed of being
written down to their net realizable value, less cost of disposal. Management
expects recovery to approximate its cost of disposal. Considerable management
judgment is necessary to estimate fair value, accordingly, actual results could
vary from such estimates. The Company anticipates completing the remainder of
the restructuring actions by the end of the third quarter of 1999.

9.  COMMITMENTS AND CONTINGENCIES

     The Company has entered into noncancellable agreements to lease certain
office and distribution facilities with remaining terms from one to eleven
years. Rental expense under the office and distribution facilities leases in
1996, 1997 and 1998 was $2,099,000,

$2,272,000 and $3,876,000, respectively. The future minimum lease payments due
under noncancellable operating leases is as follows:

</TABLE>

     For the year ended December 31, 1998, approximately 56.2% of the Company's
pharmaceutical purchases were through one wholesaler. The Company believes other
alternative sources are readily available and that no other concentration risks
exist at December 31, 1998.

     In the ordinary course of business (which includes the business conducted
by ValueRx prior to the Company's acquisition on April 1, 1998), various legal
proceedings, investigations or claims pending have arisen against the Company
and its subsidiaries (ValueRx continues to be a party to several proceedings
that arose prior to April 1, 1998). 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.

10.  EMPLOYEE BENEFIT PLANS

     RETIREMENT SAVINGS 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 a written salary deferral agreement under which a
maximum of 10% of their salary (effective January 1, 1999 maximum deferral is
12%), subject to aggregate limits required under the Internal Revenue Code, may
be contributed to the plan. The Company matches the first $2,000 of the
employee's contribution for the year. For the year ended December 1996, 1997 and
1998, the Company made contributions of approximately $639,000, $909,000 and,
$1,751,000 respectively.

     EMPLOYEE STOCK PURCHASE PLAN.  In December 1998, the Company's Board of
Directors approved an employee stock purchase plan, effective March 1, 1999,
that qualifies under Section 423 of the Internal Revenue Code and permits all
employees, excluding certain management level employees, to purchase shares of
the Company's Class A Common Stock. Participating employees may elect to
contribute up to 10% of their salary to purchase common stock at the end of each
six month participation period at a purchase price equal to 85% of the fair
market value of the common stock at the end of the participation period. Class A
Common Stock reserved for future employee purchases under the plan was 250,000
at December 31, 1998.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     DEFERRED COMPENSATION PLAN.  In December, 1998, the Compensation Committee
of the Board of Directors approved a non-qualified deferred compensation plan
(the "Executive Deferred Compensation Plan"), effective January 1, 1999, that
provides benefits payable to eligible key employees at retirement, termination
or death. Benefit payments are funded by a combination of contributions from
participants and the Company. Participants become fully vested in Company
contributions on the third anniversary of the end of the plan year for which the
contribution is credited to their account. For 1999, the annual Company
contribution will be equal to 6% of each participant's total annual
compensation, with 25% being invested in the Company's Class A Common Stock and
the remaining being allocated to a variety of investment options. As a result,
of the implementation, the Company accrued as compensation expense $797,000 in
1998 as a past service contribution which is equal to 8% of each participant's
total annual cash compensation for the period of the participant's past service
with the Company in a senior executive capacity.

11.  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 at the discretion of the
holder. At December 31, 1998, NYLIFE and the holders of Class A Common Stock
have control over approximately 89.0% and 11.0%, respectively, of the combined
voting power of all classes of Common Stock.

     In April 1996, NYLIFE converted 5,980,000 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 2,300,000 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.

     In October 1998, the Company announced a two-for-one stock split of its
Class A and Class B common stock for stockholders of record on October 20, 1998,
effective October 30, 1998. The split was effected in the form of a dividend by
issuance of one additional share of Class A Common Stock for each share of Class
A Common Stock outstanding and one additional share of Class B Common Stock for
each share of Class B Common Stock outstanding. The earnings per share and the
weighted average number of shares outstanding for basic and diluted earnings per
share have been adjusted for the stock split except on the Consolidated Balance
Sheet and the Consolidated Statement of Changes in Stockholder's Equity.

     As of December 31, 1998, the Company had repurchased a total of 475,000
shares of its Class A Common Stock under the open-market stock repurchase
program announced by the Company on October 25, 1996, although no repurchases
occurred during 1998. The Company's Board of Directors approved the repurchase
of up to 1,700,000 shares, and placed no limit on the duration of the program.
Future purchases, if any, will be in such amounts and at such times as the
Company deems appropriate based upon prevailing market and business conditions,
subject to certain restrictions in the credit agreement described above.

     As of December 31, 1998, 5,807,000 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 3).

12.  STOCK-BASED COMPENSATION PLANS

     At December 31, 1998, the Company has three fixed stock-based compensation
plans, which are described below.

     In April 1992, the Company adopted a stock option plan which it 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
1,400,000 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 140,000, to a maximum of 2,380,000 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, 1997 and 1998. A
total of 1,920,000 shares of the Company's Class A Common Stock has been
reserved for issuance under this plan. 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. The Compensation Committee has the authority to establish vesting
terms, and typically provides that the options vest over a five-year period from
the date of grant. The options may be exercised, subject to a ten-year maximum,
over a period determined by the Committee.

     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 48,000 shares to each director who is not an employee of the
Company or its affiliates. A maximum of 384,000 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. The plan provides that the options vest over a three- or five-year
period from the date of grant.

     The Company applies APB 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, 1997 and 1998. Because future options may be granted
and vesting typically occurs over a five year period, the pro forma impact shown
for 1996, 1997 and 1998 is not necessarily representative of the impact in
future years.

15.  SUBSEQUENT EVENT -- POTENTIAL ACQUISITION

     On April 1, 1999, the Company completed its acquisition of Diversified
Pharmaceutical Services, Inc. and Diversified Pharmaceutical Services (Puerto
Rico) Inc. (collectively, "DPS"), from SmithKline Beecham Corporation and
SmithKline Beecham InterCredit BV (collectively, "SB") for approximately $700
million in cash, such amount being subject to adjustment based upon the amount
of working capital of DPS at closing. The acquisition will be accounted for
under the purchase method of accounting. The Company will file an Internal
Revenue Code sec.338(h)(10) election, making amortization expense of certain
intangible assets, including goodwill, tax deductible.

     The Company used approximately $48 million of its own cash and financed the
remainder of the purchase price and related acquisition costs through a $1.05
billion credit facility with a bank syndicate led by Credit Suisse First Boston
and Bankers Trust Company, and a $150 million senior subordinated bridge credit
facility from Credit Suisse First Boston and Bankers Trust Company. The Company
also used a portion of the proceeds from the $1.05 billion credit facility to
retire the $360 million principal balance outstanding on its $440 million credit
facility (see Note 4). As a result of the retirement of the $360 million balance
outstanding on its $440 million credit facility, the Company will write-off the
remaining deferred financing fees at March 31, 1999 of $3,250,000, or
approximately $1,950,000 net of tax, as an extraordinary item during the second
quarter of 1999.

     The $1.05 billion credit facility consists of a $300 million revolving
facility, a $285 million term facility ("Term A"), and a $465 million term
facility ("Term B"). The revolving facility and the Term A facility are for a
period of six years. The Term B facility is for a period of eight years. The
provisions of this loan require quarterly interest

payments and, beginning in March 2000, annual principal payments. The interest
rate is based on a spread (the "Base Rate Margin") over several LIBOR or base
rate options, depending upon the Company's ratio of debt to EBITDA. However, the
initial base rate margin is fixed at 275 basis points for the revolving facility
and Term A facility and 350 basis points for the Term B facility for the first
two quarters. The credit facility contains covenants that limit the indebtedness
the Company may incur and the amounts of annual capital expenditures. The
covenants also establish a minimum interest coverage ratio, a maximum leverage
ratio, and a minimum fixed charge coverage ratio. In addition, the Company is
required to pay an annual fee of 50 basis points, payable in quarterly
installments, on the unused portion of the revolving facility.

     The following represents the schedule of current maturities for the Term A
and Term B facilities (in thousands):

Class A common stock are currently reserved for issuance under this plan, and
said amount will automatically increase on January 1 of each year, to and
including January 1, 2004, by an amount equal to 1% of the aggregate number of
then outstanding shares of the Company's Class A and Class B common stock.

     On May 26, 1999, the Company's stockholders approved an amendment to the
Company's certificate of incorporation to increase the number of authorized
shares of Class A common stock from 75 million to 150 million and the number of
authorized shares of Class B common stock from 22 million to 31 million.

     On June 18, 1999, the Company learned that it is named as a defendant in
Allcare Health Management Systems, Inc. v. Cerner Corporation, et al. No.
499-CV-0464-Y (N.D. TX). Plaintiff commenced this action on or about June 16,
1999, alleging infringement of a patent owned by Plaintiff on a "Wellness Health
Management System" by the Company and its wholly-owned subsidiary Diversified
Pharmaceutical Services, Inc. and ten other unrelated entities. At this stage of
the litigation, neither the merits of Plaintiff's claim nor the potential
liability associated with it, if any, can be ascertained.

     On June 18, 1999, SB transferred the ownership of Diversified Prescription
Delivery L.L.C. ("DPD"), to the Company pursuant to the Company's stock purchase
agreement with SB for the acquisition of DPS. The acquisition will be accounted
for under the purchase method of accounting.

     In June 1999, the Company completed its equity offering of 5,175,000 shares
of its Class A common stock, which includes the underwriters' over-allotments.
The Company received net proceeds of $300,393,000. The Company also completed
the sale of $250 million of 9 5/8% Senior Notes due 2009 through a private
placement, receiving net proceeds of $243,502,000. The Company used the net
proceeds from the offerings, along with approximately $25 million of its own
cash, to repay the $150 million senior subordinated bridge credit facility plus
accrued interest and $414,770,000 of the Term B facility plus accrued interest.
As a result of the retirement of a portion of the Term B facility, the Company
will write-off $7,491,000, or approximately $4,495,000 net of tax, in deferred
financing fees as an extraordinary item during the second quarter of 1999.

     The 9 5/8% Senior Notes are due June 15, 2009 and require semi-annual
interest payments beginning December 15, 1999. The Senior Notes are guaranteed
by the Company's domestic subsidiaries other than Practice Patterns Science,
Inc., Great Plains Reinsurance Company, ValueRx of Michigan, Inc., Diversified
NY IPA, Inc. and Diversified Pharmaceutical Services (Puerto Rico) Inc.. The

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 102(b)(7) of the General Corporation Law of the State of Delaware
(the "Delaware Law") enables a corporation in its original certificate of
incorporation or an amendment thereto to eliminate or limit the personal
liability of a director to a corporation or its stockholders for violations of
the director's fiduciary duty, except (1) for any breach of a director's duty of
loyalty to the corporation or its stockholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (3) pursuant to Section 174 of the Delaware Law (providing for liability of
directors for unlawful payment of dividends or unlawful stock purchases or
redemptions) or (4) for any transaction from which a director derived an
improper personal benefit. Our Restated Certificate of Incorporation provides
for the elimination of the liability of our directors to the extent permitted by
Section 102(b)(7) of the Delaware Law.

     Section 145 of the Delaware Law provides, in summary, that directors and
officers of Delaware corporations are entitled, under certain circumstances, to
be indemnified against all expenses and liabilities (including attorney's fees)
incurred by them as a result of suits brought against them in their capacity as
a director or officer, if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to our best interests, and, with
respect to any criminal action or proceeding, if they had no reasonable cause to
believe their conduct was unlawful; provided, that no indemnification may be
made against expenses in respect of any claim, issue or matter as to which they
shall have been adjudged to be liable to us, unless and only to the extent that
the court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, they are fairly and reasonably entitled to indemnity
for such expenses which the court shall deem proper. Any such indemnification
may be made by us only as authorized in each specific case upon a determination
by our stockholders or disinterested directors that indemnification is proper
because the indemnitee has met the applicable standard of conduct. Article Seven
of our certificate of incorporation entitles our officers and directors to
indemnification to the fullest extent permitted by Section 145 of the Delaware
Law, as the same may be supplemented from time to time.

     Article Eight of our certificate of incorporation provides that no director
shall have any personal liability to us or our stockholders for any monetary
damages for breach of fiduciary duty as a director, provided that such provision
does not limit or eliminate the liability of any director (1) for breach of such
director's duty of loyalty to us or our stockholders, (2) for acts or omissions
not in good faith or which involve international misconduct or knowing violation
of the law, (3) under Section 174 of the Delaware Law (involving certain
unlawful dividends or stock repurchases) or (4) for any transaction from which
such director derived an improper personal benefit.

ITEM 22. UNDERTAKINGS

     The undersigned registrant hereby undertakes:

     1. To file, during any period in which offers or sales are being made of
        the securities registered hereby, a post-effective amendment to this
        registration statement:

        a. To include any prospectus required by Section 10(a)(3) of the
           Securities Act;

        b. To reflect in the prospectus any facts or events arising after the
           effective date of this registration statement (or the most recent
           post-effective amendment thereof) which, individually or in the
           aggregate, represent a fundamental change in the information set
           forth in this registration statement. Notwithstanding the foregoing,
           any increase or decrease in volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high end of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the SEC pursuant to Rule 424(b) if, in the
           aggregate, the changes in volume and price represent no more than a
           20% change in the maximum aggregate offering price set forth in the
           "Calculation of Registration Fee" table in the effective registration
           statement; and

        c. To include any material information with respect to the plan of
           distribution not previously disclosed in this registration statement
           or any material change to such information in this registration
           statement;

                                      II-2
<PAGE>   143

        provided, however, that the undertakings set forth in paragraphs (a) and
        (b) above shall not apply if the information required to be included in
        a post-effective amendment by those paragraphs is contained in periodic
        reports filed by the registrant pursuant to Section 13 or Section 15(d)
        of the Exchange Act that are incorporated by reference in this
        registration statement.

     2. That, for the purpose of determining any liability under the Securities
        Act, each such post-effective amendment will be deemed to be a new
        registration statement relating to the securities offered herein, and
        the offering of such securities at that time will be deemed to be the
        initial bona fide offering thereof.

     3. To remove from registration by means of a post-effective amendment any
        of the securities being registered which remain unsold at the
        termination of the offering.

     4. That, for purposes of determining any liability under the Securities
        Act, each filing of the registrant's annual report pursuant to Section
        13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
        filing of an employee benefit plan's annual report pursuant to Section
        15(d) of the Exchange Act) that is incorporated by reference in this
        registration statement will be deemed to be a new registration statement
        relating to the securities offered herein, and the offering of such
        securities at that time will be deemed to be the initial bona fide
        offering thereof.

     5. To respond to requests for information that is incorporated by reference
        into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form,
        within one business day of receipt of such request, and to send the
        incorporated documents by first class mail or other equally prompt
        means. This includes information contained in documents filed subsequent
        to the effective date of the registration statement through the date of
        responding to the request.

     6. To supply by means of a post-effective amendment all information
        concerning a transaction, and the company being acquired involved
        therein, that was not the subject of and included in the registration
        statement when it became effective.

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

                     [SIMPSON THACHER & BARTLETT LETTERHEAD]



                                                  August 4, 1999



Express Scripts, Inc.
13900 Riverport Drive
Maryland Heights, MO 63043

Ladies and Gentlemen:


     We have acted as counsel to Express Scripts, Inc., a Delaware corporation
(the "Company"), and the subsidiaries of the Company named in Exhibit A and
Exhibit B hereto (individually, a "Guarantor" and collectively, the
"Guarantors"), in connection with the Registration Statement on Form S-4 (the
"Registration Statement") filed by the Company and the Guarantors with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended, relating to the issuance by the Company of $250,000,000
aggregate principal amount of 9 5/8% Senior Notes due 2009 (the "Exchange
Securities") and the issuance by the Guarantors of guarantees (the
"Guarantees"), with respect to the Exchange Securities. The Exchange Securities
and the Guarantees will be issued under an indenture (the "Indenture") dated as
of June 16, 1999, among the Company the Guarantors and Bankers Trust Company, as
Trustee. The Exchange Securities will be offered by the Company in exchange for
$250,000,000 aggregate principal amount of its outstanding 9 5/8% Senior Notes
due 2009 (the "Securities").

Express Scripts, Inc.                   -2-                       August 4, 1999


     We have examined the Registration Statement and the Indenture, which has
been filed with the Commission as an exhibit to the Registration Statement. We
also have examined the originals, or duplicates or certified or conformed
copies, of such records, agreements, instruments and other documents and have
made such other and further investigations as we have deemed relevant and
necessary in connection with the opinions expressed herein. As to questions of
fact material to this opinion, we have relied upon certificates of public
officials and of officers and representatives of the Company and the Guarantors.

     In rendering the opinions set forth below, we have assumed the genuineness
of all signatures, the legal capacity of natural persons, the authenticity of
all documents submitted to us as originals, the conformity to original documents
of all documents submitted to us as duplicates or certified or conformed copies,
and the authenticity of the originals of such latter documents. We also have
assumed that the Indenture is the valid and legally binding obligation of the
Trustee.

     We have assumed further that (1) the Subsidiaries listed in Exhibit B
hereto (the "Non-Delaware Guarantors") have duly authorized, executed and
delivered the Indenture and (2) execution, delivery and performance by the
Non-Delaware Guarantors of the Indenture and the Guarantees do not and will not
violate the laws of the respective jurisdictions in which such Non-Delaware
Guarantors are organized (as set forth next to the name of each Non-Delaware
Guarantor in Exhibit B hereto) or any other applicable laws (excepting the laws
of the State of New York and the Federal laws of the United States).

Express Scripts, Inc.                   -3-                       August 4, 1999


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

     1. When the Exchange Securities have been duly executed, authenticated,
issued and delivered in accordance with the provisions of the Indenture upon the
exchange, the Exchange Securities will constitute valid and legally binding
obligations of the Company enforceable against the Company in accordance with
their terms.

     2. When (a) the Exchange Securities have been duly executed, authenticated,
issued and delivered in accordance with the provisions of the Indenture upon the
exchange and (b) the Guarantees have been duly issued, the Guarantees will
constitute valid and legally binding obligations of the Guarantors enforceable
against the Guarantors in accordance with their terms.

     Our opinions set forth above are subject to the effects of (1) bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally, (2) general equitable
principles (whether considered in a proceeding in equity or at law) and (3) an
implied covenant of good faith and fair dealing.

     We are members of the Bar of the State of New York, and we do not express
any opinion herein concerning any law other than the law of the State of New
York, the Federal law of the United States and the Delaware General Corporation
Law.

such other business as may properly come before said meeting.

SECTION 2. Special meetings of stockholders other than those regulated by

SECTION 3. At all meetings of stockholders, there shall be present, either in

bound by, such Rules and Regulations.

SECTION 5. Regular meetings of the Board of Directors shall be held from time
to time on the third Tuesday of the month. If the day appointed for holding

on such day shall be held on the next business day thereafter. Special meetings
of the Board of Directors may be called upon at least two day's notice whenever

Officer or, in their absence, by such other director as the Board of Directors

session, and shall keep minutes of its proceedings, which shall be presented to
the Board of Directors at its next subsequent meeting. All acts done and powers
and authority conferred by the Executive Committee from time to time shall be
and be deemed to be, and may be certified as being, the act and under the
authority of the Board of Directors.

A majority of the Committee shall constitute a quorum, but the Committee may
act only by the concurrent vote of not less than one-third of its members, at
least one of whom must be a director other than an officer. Any one or more
directors, even though not members of the Executive Committee, may attend any
meeting of the Committee, and the member or members of the Committee present,
even though less than a quorum, may designate any one or more of such directors
as a substitute or substitutes for any absent member or members of the
Committee, and each such substitute or substitutes shall be counted for quorum,
voting, and all other purposes as a member or members of the Committee.

SECTION 2. There shall be an Audit Committee appointed annually by resolution
adopted by a majority of the entire Board of Directors which shall consist of

time to time be fixed by resolution adopted by the Board of Directors. The
Chairman shall be designated by the Board of Directors, who shall also from
time to time fix a quorum for meetings of the Committee. Such Committee shall

of the Company, to make studies of the Company's assets and liabilities as the
Committee may request and to make an examination of the accounting and auditing
methods of the Company and its system of internal protective controls to the
extent considered necessary or advisable in order to determine that the
operations of the Company, including its fiduciary departments, are being
audited by the General Auditor in such a manner as to provide prudent and
adequate protection. The Committee also may direct the General Auditor to make
such investigation as it deems necessary or advisable with respect to the
Company, its various departments and the conduct of its operations. The
Committee shall hold regular quarterly meetings and during the intervals
thereof shall meet at other times on call of the Chairman.

Board or the Chairman of the Board or the Chief Executive Officer or, in their
absence, the President, the Senior Vice Chairman or any Vice Chairman. The

                                   ARTICLE V

               INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

SECTION 1. The Company shall, to the fullest extent permitted by Section 7018
of the New York Banking Law, indemnify any person who is or was made, or
threatened to be made, a party to an action or proceeding, whether civil or
criminal, whether involving any actual or alleged breach of duty, neglect or
error, any accountability, or any actual or alleged misstatement, misleading
statement or other act or omission and whether brought or threatened in any
court or administrative or legislative body or agency, including an action by
or in the right of the Company to procure a judgment in its favor and an action
by or in the right of any other corporation of any type or kind, domestic or
foreign, or any partnership, joint venture, trust, employee benefit plan or
other enterprise, which any director or officer of the Company is servicing or
served in any capacity at the request of the Company by reason of the fact that
he, his testator or intestate, is or was a director or officer of the Company,
or is serving or served such other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise in any capacity, against
judgments, fines, amounts paid in settlement, and costs, charges and expenses,
including attorneys' fees, or any appeal therein; provided, however, that no
indemnification shall be provided to any such person if a judgment or other
final adjudication adverse to the director or officer establishes that (i) his
acts were committed in bad faith or were the result of active and deliberate
dishonesty and, in either case, were material to the cause of action so
adjudicated, or (ii) he personally gained in fact a financial profit or other
advantage to which he was not legally entitled.

SECTION 2. The Company may indemnify any other person to whom the Company is
permitted to provide indemnification or the advancement of expenses by
applicable law, whether pursuant to rights granted pursuant to, or provided by,
the New York Banking Law or other rights created by (i) a resolution of
stockholders, (ii) a resolution of directors, or (iii) an agreement providing
for such indemnification, it being expressly intended that these By-Laws
authorize the creation of other rights in any such manner.

SECTION 3. The Company shall, from time to time, reimburse or advance to any
person referred to in Section 1 the funds necessary for payment of expenses,
including attorneys' fees, incurred in connection with any action or proceeding
referred to in Section 1, upon receipt of a written undertaking by or on behalf
of such person to repay such amount(s) if a judgment or other final
adjudication adverse to the director or officer establishes that (i) his acts
were committed in bad faith or were the result of active and deliberate
dishonesty and, in either case, were material to the cause of action so
adjudicated, or (ii) he personally gained in fact a financial profit or other
advantage to which he was not legally entitled.

SECTION 4. Any director or officer of the Company serving (i) another
corporation, of which a majority of the shares entitled to vote in the election
of its directors is held by the Company, or (ii) any employee benefit plan of
the Company or any corporation referred to in clause (i) in any capacity shall
be deemed to be doing so at the request of the Company. In all other cases, the
provisions of this Article V will apply (i) only if the person serving another
corporation or any partnership, joint venture, trust, employee benefit plan or
other enterprise so served at the specific request of the Company, evidenced by
a written communication signed by the Chairman of the Board, the Chief
Executive Officer or the



<PAGE>   15

President, and (ii) only if and to the extent that, after making such efforts
as the Chairman of the Board, the Chief Executive Officer or the President
shall deem adequate in the circumstances, such person shall be unable to obtain
indemnification from such other enterprise or its insurer.

SECTION 5. Any person entitled to be indemnified or to the reimbursement or
advancement of expenses as a matter of right pursuant to this Article V may
elect to have the right to indemnification (or advancement of expenses)
interpreted on the basis of the applicable law in effect at the time of
occurrence of the event or events giving rise to the action or proceeding, to
the extent permitted by law, or on the basis of the applicable law in effect at
the time indemnification is sought.

SECTION 6. The right to be indemnified or to the reimbursement or advancement
of expense pursuant to this Article V (i) is a contract right pursuant to which
the person entitled thereto may bring suit as if the provisions hereof were set
forth in a separate written contract between the Company and the director or
officer, (ii) is intended to be retroactive and shall be available with respect
to events occurring prior to the adoption hereof, and (iii) shall continue to
exist after the rescission or restrictive modification hereof with respect to
events occurring prior thereto.

SECTION 7. If a request to be indemnified or for the reimbursement or
advancement of expenses pursuant hereto is not paid in full by the Company
within thirty days after a written claim has been received by the Company, the
claimant may at any time thereafter bring suit against the Company to recover
the unpaid amount of the claim and, if successful in whole or in part, the
claimant shall be entitled also to be paid the expenses of prosecuting such
claim. Neither the failure of the Company (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of or
reimbursement or advancement of expenses to the claimant is proper in the
circumstance, nor an actual determination by the Company (including its Board
of Directors, independent legal counsel, or its stockholders) that the claimant
is not entitled to indemnification or to the reimbursement or advancement of
expenses, shall be a defense to the action or create a presumption that the
claimant is not so entitled.

SECTION 8. A person who has been successful, on the merits or otherwise, in the
defense of a civil or criminal action or proceeding of the character described
in Section 1 shall be entitled to indemnification only as provided in Sections
1 and 3, notwithstanding any provision of the New York Banking Law to the
contrary.

shares properly assigned for transfer.
