NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Summary of Significant Accounting Policies

         Certain  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/A for the Year Ended  December 31, 1998, as filed with the  Securities
and Exchange Commission on June 10, 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 September 30, 1999,  the  Unaudited  Consolidated  Statement of
Operations  for the three months and nine months ended  September 30, 1999,  and
1998, the Unaudited  Consolidated  Statement of Changes in Stockholders'  Equity
for the nine months ended  September 30, 1999,  and the  Unaudited  Consolidated
Statement of Cash Flows for the nine months ended  September  30, 1999 and 1998.
Operating  results for the three months and nine months ended September 30, 1999
are not necessarily  indicative of the results that may be expected for the year
ending December 31, 1999.

Note 2 - Receivables

         As of September  30, 1999 and December 31, 1998,  unbilled  receivables
were  $274,281,000  and  $209,334,000,  respectively.  Unbilled  receivables are
billed to  clients  typically  within 30 days based on the  contractual  billing
schedule agreed with the client.

Note 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.

Note 4 - 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 $718
million,  which includes a purchase price adjustment for closing working capital
and  transaction   costs.  The  Company  will  file  an  Internal  Revenue  Code
ss.338(h)(10)  election,  making  amortization  expense  of  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 and a $150 million
senior  subordinated  bridge credit  facility (see Note 4). On June 18, 1999, SB
transferred  ownership of Diversified  Prescription  Delivery L.L.C. ("DPD"), to
the Company,  pursuant to the Company's agreement with SB in connection with the
acquisition of DPS.

         The  acquisition  has been  accounted for using the purchase  method of
accounting.  The  results  of  operations  of  DPS  have  been  included  in the
consolidated  financial  statements  and  pharmacy  benefit  management  ("PBM")
segment since April 1, 1999. 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 has
been  preliminarily  allocated to other intangible assets consisting of customer
contracts  in the amount of  $129,500,000  which are being  amortized  using the
straight-line  method over the  estimated  useful lives of 1 to 20 years and are
included in other intangible  assets, and goodwill in the amount of $730,309,000
which is being  amortized  using the  straight-line  method  over the  estimated
useful life of 30 years. In conjunction with the  acquisition,  DPS retained the
following liabilities:

         On April 1, 1998, the Company  acquired all of the outstanding  capital
stock  of  Value   Health,   Inc.  and  Managed   Prescription   Network,   Inc.
(collectively,  known as "ValueRx")  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 bank credit facility
(see Note 4) and the remainder  from the Company's  cash balances and short-term
investments.

         The  acquisition  has been  accounted for using the purchase  method of
accounting  and the results of  operations  of ValueRx 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.  The
amortization   expense   from  ValueRx   goodwill  and  customer   contracts  is
non-deductible for income tax purposes. In conjunction with the acquisition, the
Acquired Entities and their subsidiaries retained the following liabilities:

         The  following  unaudited pro forma  information  presents a summary of
combined  results  of  operations  of the  Company,  DPS and  ValueRx  as if the
acquisitions had occurred at the beginning of the periods presented,  along with
certain pro forma adjustments to give effect to amortization of goodwill,  other
intangible  assets,  interest expense on acquisition debt and other adjustments.
The pro forma financial information is not necessarily indicative of the results
of operations as they would have been had the  transaction  been effected on the
assumed dates.  Included in the pro forma  information  are certain  integration
costs incurred by the Company that are being reported  within  selling,  general
and  administrative  expenses  in the  statement  of  operations.  The pro forma
information  for the nine  months  ended  September  30,  1998  assumes the debt
incurred to acquire DPS is  outstanding  for the nine  months and  excludes  the
impact of the Company's  recapitalization from its equity and debt offering (see
Note 5).

         On April 1, 1999, the Company  executed a $1.05 billion credit facility
("Credit  Facility") with a bank syndicate led by Credit Suisse First Boston and
Bankers Trust Company,  consisting of $750 million in term loans, including $285
million  of Term A loans and $465  million of Term B loans,  and a $300  million
revolving credit  facility.  The Credit Facility is secured by the capital stock
of  each  of  the  Company's   existing  and  subsequently   acquired   domestic
subsidiaries,  excluding Practice Patterns Science,  Inc. ("PPS"),  Great Plains
Reinsurance Company ("Great Plains"),  ValueRx of Michigan, Inc., Diversified NY
IPA, Inc., and Diversified  Pharmaceutical  Services (Puerto Rico), Inc., and is
also  secured by 65% of the stock of the  Company's  foreign  subsidiaries.  The
provisions of the Credit Facility require  quarterly  interest payments based on
several London  Interbank  Offered Rates  ("LIBOR") or base rate options plus an
interest rate spread.  The Credit  Facility  contains  covenants  that limit the
indebtedness  the  Company  may incur,  dividends  paid 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 0.5%,  payable in
quarterly  installments,  on the unused portion of the revolving credit facility
($160 million at September 30, 1999).  At September 30, 1999, the Company was in
compliance with all covenants associated with the Credit Facility.

         Also on April 1,  1999,  the  Company  executed a $150  million  senior
subordinated  bridge credit facility with Credit Suisse First Boston and Bankers
Trust Company. The proceeds from this facility and approximately $890 million in
proceeds from the Credit  Facility were used to consummate  the DPS  acquisition
(see Note 3) and repay $360 million outstanding under the Company's pre-existing
$440 million credit  facility.  This facility was retired in June 1999, upon the
completion of the Company's equity offering (see Note 6).

         On June 16, 1999, the Company completed the offering of $250 million in
Senior Notes through a private  placement  under Rule 144A of the Securities Act
of 1933, as amended. The Company filed a registration statement (No. 333-83133),
which was declared effective on August 4, 1999, to exchange the privately placed
Senior Notes for registered  Senior Notes on  substantially  the same terms. The
exchange was completed on September 21, 1999. The Senior Notes require  interest
to be paid  semi-annually  on June 15th and December 15th. The Senior Notes also
provide the Company an opportunity to call the debt at specified rates beginning
in June 2004.  The net  proceeds  from the Senior Notes  offering,  along with a
portion of the net  proceeds  from the equity  offering and  $23,901,000  of the
Company's own cash were used to repay  $414,770,000 of the Term B loans. In July
1999,  the  Company  paid  off  the  remaining  Term  B  principal   balance  of
$50,230,000.  As a result of the refinancing of the $440 million credit facility
and the repayment of the Term B loans, the Company recognized a $7,150,000,  net
of tax,  extraordinary  loss from the write-off of deferred  financing fees. 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, and  Diversified  Pharmaceutical  Services
(Puerto Rico).  The following is a summary of financial  position and results of
operations  of the issuer,  the  guarantor  subsidiaries  and the  non-guarantor
subsidiaries:

</TABLE>

         To manage its 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 September 30, 1999, the
swap had a notional  principal  amount of $333  million.  Under the terms of the
swap, the Company agreed 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  $27 million in October  1999,  increasing to $36 million in
April 2000,  to $45 million in April 2001 and to $48 million in April 2002. As a
result, the Company has, in effect,  converted $333 million of its variable rate
debt  under the  Credit  Facility  to fixed rate debt at 5.88% per annum for the
first four years of the Credit Facility, plus the interest rate spread of 2.0%.

         On June 17,  1999,  the  Company  entered  into an  interest  rate swap
agreement with Bankers Trust Company.  The swap will not become  effective until
April 2000 and carried no notional  principal  amount as of September  30, 1999.
Under the terms of the agreement,  the Company agreed to receive a floating rate
of interest on the notional  principal amount based on a three-month  LIBOR rate
in  exchange  for  payment  of a fixed  rate of  interest  of 6.25%  per  annum.
Beginning in April 2000, the notional  principal  amount will be $15 million and
will increase  semi-annually  up to an  approximate  $137.25  million in October
2002. For the remainder of the agreement's  term, the notional  principal amount
will amortize until the agreement terminate in April 2005. When the swap becomes
effective, the Company will, in effect, convert the notional principal amount of
our variable rate debt under our Credit Facility to fixed rate debt at 6.25% per
annum, plus the interest rate spread.

Note 6 - Restructuring

         During  the  second  quarter of 1999,  the  Company  recorded a pre-tax
restructuring  charge of $9,400,000  ($5,773,000  after taxes or $0.17 per basic
and diluted share) associated with the consolidation of the Company's  Plymouth,
Minnesota  facility  into the Company's  Bloomington,  Minnesota  facility.  The
consolidation  plan includes the relocation of all non-call center  employees at
the Plymouth facility to the Bloomington  facility  beginning in August 1999 and
ending in February 2000.  Included in the  restructuring  charge are anticipated
cash  expenditures of  approximately  $5,700,000 for lease  termination fees and
rent on  unoccupied  space and  anticipated  non-cash  charges of  approximately
$3,700,000  for the  write-down  of leasehold  improvements  and  furniture  and
fixtures.  The  restructuring  charge does not include any costs associated with
the physical relocation of the employees.

         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  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 Company completed the remainder of the restructuring actions
during the third quarter of 1999.

         Both  restructuring  charges include  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.

Note 7 - Common Stock

         In June 1999, the Company  consummated its offering of 5,175,000 shares
of its Class A common  stock at a price of $61 per share.  The net  proceeds  of
$299,381,000  were used to retire the $150 million  senior  subordinated  bridge
credit facility and a portion of the Term B loans under the $1.05 billion credit
facility (see Note 5).

Note 8 - 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 operating  segment
that 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 nine months ended September 30:

</TABLE>

         As of September  30, 1999 and  December 31, 1998,  total assets for the
PBM segment were $2,078,718 and  $1,068,715,000,  respectively,  and the Non-PBM
segment were $26,318,000 and $26,746,000, respectively.

Note 9 - Subsequent Events

         In October  1999,  the Company  completed its  contribution  of certain
operating  assets  constituting  its  e-commerce  business  ("YourPharmacy")  in
prescription  and   non-prescription   drugs  and  health  and  beauty  aids  to
PlanetRx.com,  Inc.  ("PlanetRx")  in exchange for 19.9% of the common equity of
PlanetRx.   As  a  result,   the  Company  will  record  an  after-tax  gain  of
approximately $101 million on the sale of these assets during the fourth quarter
of 1999.  Additionally,  during the fourth  quarter of 1999,  the  Company  will
record an after-tax  stock  compensation  expense of  approximately  $12 million
related to employees of  YourPharmacy.  These amounts were determined  using the
$16 per share initial offering price for PlanetRx's equity.

Overview

         On  April 1,  1999,  we  completed  our  second  major  acquisition  by
acquiring   Diversified    Pharmaceutical   Services,   Inc.   and   Diversified
Pharmaceutical  Services (Puerto Rico) Inc. (collectively "DPS") from SmithKline
Beecham Corporation ("SmithKline Beecham") and SmithKline Beecham InterCredit BV
for approximately  $718 million,  which includes a purchase price adjustment for
closing working capital and transaction  costs. On April 1, 1998, we consummated
our first  major  acquisition  by  acquiring  Value  Health,  Inc.  and  Managed
Prescription  Network,  Inc.  (collectively,  "ValueRx"),  the pharmacy  benefit
management   ("PBM")   operations   of   Columbia/HCA   Healthcare   Corporation
("Columbia"), for approximately $460 million in cash, which includes transaction
costs and executive management severance costs of approximately $6.7 million and
$8.3 million, respectively. Consequently, our operating results include those of
DPS from April 1, 1999 and ValueRx from April 1, 1998.  The net assets  acquired
from  DPS have  been  preliminarily  recorded  at their  estimated  fair  value,
resulting in $730,309,000 of goodwill that is being amortized over 30 years. The
net assets  acquired  from ValueRx have been  recorded at their  estimated  fair
value,  resulting in  $278,113,000  of goodwill that is being  amortized over 30
years.  Both  acquisitions  have been accounted for under the purchase method of
accounting.

         As of September 30, 1999, our membership was approximately 37.5 million
members,  excluding  approximately 9.5 million members of health plans of United
HealthCare Corp.  ("UHC") whose contract  expires in May 2000,  compared to 36.0
million members as of June 30, 1999 and to 23.0 million members as of October 1,
1998.  The increase  from June 30, 1999 is primarily due to the addition of Blue
Cross and Blue Shield of  Massachusetts.  The  increase  from October 1, 1998 is
primarily due to our acquisition of DPS. This acquisition enabled us to have one
of the largest managed care  membership  bases of any PBM.  Although  membership
counts are based on our  electronic  eligibility  data file,  they  involve some
estimates,  extrapolations and  approximations.  For example,  some plan designs
allow  for  family  coverage  under  one  identification  number,  and  we  make
assumptions  about the average number of persons per family in  calculating  our
total membership.  Because these  assumptions may vary between PBMs,  membership
counts may not be comparable between our competitors and us. However, we believe
our  membership  count  provides a reasonable  estimation  of the  population we
serve. The acquisitions  also increased the scale of our business,  expanded our
client base,  increased our  penetration of PBM markets and expanded our product
and service offerings.

         We derive our revenues  primarily  from the sale of PBM services in the
United States and Canada. Our PBM net revenues generally include  administrative
fees,  dispensing fees and ingredient  costs of  pharmaceuticals  dispensed from
retail  pharmacies  included  in one of our  networks  or from  one of our  mail
pharmacies (the "Gross Basis").  We then record the associated  costs in cost of
revenues.  Where we only  administer  the contracts  between our clients and the
clients' retail pharmacy networks,  or where we are not contractually  obligated
to pay the pharmacy for the ingredient cost of dispensed drugs, we record as net
revenues only the  administrative  fees we receive from our activities (the "Net
Basis").  We also derive PBM net  revenues  from the sale of  informed  decision
counseling  services  through our Express Health LineSM division and the sale of
medical  information  management  services,  which include  provider  profiling,
formulary  management  support  services and outcomes  assessments,  through our
Practice Patterns  Science,  Inc.  subsidiary.  Non-PBM net revenues are derived
from:

o    The sale of  pharmaceuticals  for and the  provision  of  infusion  therapy
     services  through our IVTx, Inc.  subsidiary,  now operating under the name
     Express Scripts Infusion Services

o    Administrative  fees received from drug manufacturers for the dispensing or
     distribution of pharmaceuticals through our Specialty Distribution Services
     division.

o    Administrative  fees received for members using our vision program  through
     our  alliance  with Cole Managed  Vision  ("Cole"),  a  subsidiary  of Cole
     National Corporation

</TABLE>

         Total  net   revenues   for  the  third   quarter  of  1999   increased
$276,177,000,  or 34.2%,  compared to the third quarter of 1998. The increase is
primarily due to the increase in the number of retail  pharmacy  network  claims
and mail pharmacy claims processed, and the acquisition of DPS. Although the DPS
acquisition  approximately  doubled the size of our membership  base, it did not
double the size of our  revenues  because DPS records all of its revenues on the
Net Basis.

         Total  net  revenues  for the nine  months  ended  September  30,  1999
increased $993,245,000, or 50.0%, compared to the first nine months of 1998. The
increase is primarily  due to the  inclusion of ValueRx for the full nine months
of 1999  compared to only the second and third  quarters of 1998,  the increased
processing of retail pharmacy network claims and mail pharmacy  claims,  and the
acquisition of DPS.

         The majority of the  increase in net revenues for the third  quarter of
1999 and the nine months ended 1999 were derived from our PBM services.  Network
pharmacy claims  processed  increased  149.0% and 135.1% in the third quarter of
1999 over 1998 and the first nine  months of 1999 over 1998,  respectively.  The
significant  increase  in the third  quarter  of 1999  network  pharmacy  claims
processed is primarily due to the acquisition of DPS and, to a lesser extent,  a
larger  membership  base utilizing our network  pharmacy  services and increased
utilization by existing  members.  The  significant  increase in the nine months
ended September 30, 1999 network pharmacy claims is due to the factors above and
the  inclusion of ValueRx for the full nine months of 1999  compared to only the
second and third quarters of 1998. The average net revenue per network  pharmacy
claim  decreased  47.8% and 35.9% in the third quarter of 1999 over 1998 and the
first nine months of 1999 over 1998,  respectively.  The  decrease is due to the
acquisition of DPS, as DPS records revenue on the Net Basis which  substantially
reduces the average net revenue per network  pharmacy claim.  Excluding DPS, the
average net revenue per network  pharmacy  claim  increased 3.2% and 6.9% in the
third  quarter  of 1999 over 1998 and the first  nine  months of 1999 over 1998,
respectively. The increase for the first nine months of 1999 is primarily due to
the  inclusion of ValueRx for the full nine months of 1999  compared to only the
second and third quarters of 1998.  ValueRx recorded revenues on the Gross Basis
as substantially all ValueRx clients used retail pharmacy  networks  established
by ValueRx,  rather than retail  pharmacy  networks  established by its clients,
resulting in our recording  dispensing fees and ingredient costs in net revenues
and cost of revenues,  respectively.  Excluding ValueRx and DPS, we historically
have recorded revenues under both the Gross Basis and the Net Basis. As a result
of  the  above  factors,   network   pharmacy  claims  net  revenues   increased
$172,787,000, or 30.0%, and $713,309,000, or 50.7%, in the third quarter of 1999
over 1998 and the first nine months of 1999 over 1998, respectively.

         Mail pharmacy claims  processed  increased 36.0% and 41.0% in the third
quarter  of 1999  over  1998  and the  first  nine  months  of 1999  over  1998,
respectively.  The  significant  increase for the third  quarter of 1999 and the
first  nine  months  of  1999 is  primarily  due to the  acquisition  of the DPD
facility  and  increased  utilization  by existing  members.  In  addition,  the
increase for the first nine months of 1999 is partially  due to the inclusion of
ValueRx for the full nine  months of 1999  compared to only the second and third
quarters of 1998. The average net revenue per mail pharmacy claim increased 8.2%
and 6.4% in the third  quarter  of 1999 over 1998 and the first  nine  months of
1999 over  1998,  respectively.  Due to the above  factors,  mail  pharmacy  net
revenues  increased  $98,263,000,  or 47.2%,  and  $260,740,000 or 50.1%, in the
third  quarter  of 1999 over 1998 and the first  nine  months of 1999 over 1998,
respectively.

         Net revenues from our non-PBM services  increased 6.7% and 10.0% in the
third  quarter  of 1999 over 1998 and the first  nine  months of 1999 over 1998,
respectively.  The increases were primarily due to a change in product mix sold,
which resulted in higher drug ingredient  costs.  These increases were partially
offset by the reduction in net revenues from our managed vision  business due to
the restructuring of this operation.

</TABLE>

         Our  cost of  revenues  for PBM  services  as a  percentage  of PBM net
revenues  decreased  during  the third  quarter of 1999 over 1998 and during the
first nine months of 1999 over 1998 primarily due to the  acquisition of DPS. As
previously  stated, DPS records revenues under the Net Basis. In future periods,
we expect the gross margin  percentage  will be greater than prior periods until
we begin the process of  converting  DPS clients to our  pharmacy  networks,  at
which time we will begin  recording  revenues on the Gross Basis and  anticipate
that the gross margin percentage will begin to decline,  although  profitability
is not expected to be adversely  affected by these  changes.  Excluding DPS, the
gross margin  percentage  for the third  quarter of 1999  decreased to 7.3% from
8.2% for the third quarter of 1998.  The decrease is primarily due to lower drug
ingredient  margins  resulting from our  acquisition of DPD and the inclusion of
its results in our  operations.  The gross margin  percentage for the first nine
months of 1999 decreased to 7.9% from 8.0% for the first nine months of 1998.

         Cost of revenues for non-PBM  services  increased  as a  percentage  of
non-PBM  net  revenues  from the third  quarter of 1999 over 1998 and during the
first nine months of 1999 over 1998.  The increase  during the third  quarter is
primarily  due to overhead  costs  expanding at a faster  rate,  and to a lesser
extent,  the change in the product mix sold. The increase  during the first nine
months of 1999 is due to the continued  change in the product mix sold resulting
in additional costs of approximately  $2,163,000 during the first nine months of
1999.  This change was partially  offset by our development of new business that
generated  higher  gross  margins  and the  reduction  of overhead  costs,  as a
percentage of non-PBM net revenues, due to the change in product mix sold.

         Selling,  general and administrative  expenses,  excluding depreciation
and amortization, increased $23,438,000, or 63.5%, for the third quarter of 1999
compared to 1998 and  $75,390,000,  or 85.0%,  for the first nine months of 1999
over 1998.  The increases are primarily  due to our  acquisition  of DPS,  costs
incurred  during the  integration of DPS and ValueRx,  costs incurred in funding
our  Internet  operations,  and costs  required  to expand the  operational  and
administrative  support functions to enhance management of the pharmacy benefit.
The  increase  for the  first  nine  months of 1999 over 1998 is also due to the
inclusion  of  ValueRx  for the full nine  months of 1999  compared  to only the
second and third  quarters of 1998. As a percentage  of net  revenues,  selling,
general and administrative  expenses,  excluding  depreciation and amortization,
for the third quarter of 1999 and for the first nine months of 1999 increased to
5.6%  and  5.5%  from  4.5%  and  4.4%  for  the  comparable  periods  in  1998,
respectively.  The  increase in the  percentage  of net  revenues  is  primarily
attributed  to  DPS's  recording  revenue  on the Net  Basis,  as  discussed  in
"Overview" and "--Net Revenues."

         As part of our  overall  plan to achieve  operating  economies,  we are
integrating  DPS (including  DPD) and ValueRx into our historical  business.  To
date, we have substantially met our integration goals.  During the third quarter
of 1999, the manufacturing programs and processes were combined, the majority of
the DPD mail order volume was integrated into our existing mail pharmacies,  our
Minneapolis  facilities  were  substantially  consolidated,  we  launched  a new
corporate branding program to market the strengths of the combined organization,
and we completed the  reorganization  of the sales and client  services teams to
become more responsive to client needs. During the third quarter of 1999 and the
first nine months of 1999,  we  capitalized  $3,119,000  and  $5,675,000  in new
systems   development  costs  and  we  expensed  $2,312,000  and  $6,754,000  in
incremental integration costs, respectively.

         Depreciation and amortization  substantially increased during the third
quarter  of 1999  over  1998 and the  first  nine  months  of 1999 over 1998 due
principally to the acquisition of DPS and, to a lesser extent,  the inclusion of
ValueRx for the entire nine-month  period.  During the second and third quarters
of 1999,  we recorded  amortization  expense for goodwill  and other  intangible
assets of  $24,063,000  associated  with the  acquisition  of DPS. The remaining
increase  during the third  quarter of 1999 and the first nine months of 1999 is
primarily  due to  the  expansion  of  our  operations  and  enhancement  of our
information systems to better manage the pharmacy benefit.

         The corporate restructuring charge for the first nine months of 1999 is
due  to  the  consolidation  of  our  Plymouth,   Minnesota  facility  into  our
Bloomington,  Minnesota facility. The consolidation plan includes the relocation
of all non-call  center  employees at our Plymouth  facility to our  Bloomington
facility  beginning in August 1999 and ending in February 2000.  Included within
the  restructuring  charge are anticipated  cash  expenditures of  approximately
$5,700,000  for  lease  termination  fees  and  rent  on  unoccupied  space  and
anticipated  non-cash charges of  approximately  $3,700,000 for the write-off of
leasehold improvements and furniture and fixtures. The restructuring charge does
not include any costs associated with the physical relocation of the employees.

amortization  of deferred  financing fees of $506,000 and $203,000 for the three

$609,000 for the nine months ended September 30, 1999 and 1998, respectively.

         The significant increase in interest expense is due to our financing of
the DPS  acquisition  with $890 million in  borrowings  under our $1.05  billion
credit  facility  and a $150 million  bridge  credit  facility,  as discussed in
"Liquidity  and Capital  Resources."  The  increase for the first nine months of
1999 over 1998 is also due to the acquisition of ValueRx occurring in the second
quarter of 1998.  Interest  expense for the first  quarter of 1998 was  nominal.
Interest income  decreased during the first nine months of 1999 over 1998 due to
our  investment of cash balances and short-term  investments at higher  interest
rates in 1998 than those  received in 1999.  Had our equity  offering and Senior
Notes  offering (see  "Liquidity  and Capital  Resources")  been completed as of
April 1, 1999,  interest  expense for the nine months ending  September 30, 1999
would have been reduced by approximately $6,200,000.

</TABLE>

         Our  effective  tax rate  decreased  for the third quarter of 1999 from
1998  primarily  due to the increase in income before income taxes to reduce the
impact  of  the  non-deductible  goodwill  and  customer  contract  amortization
associated  with our ValueRx  acquisition.  The goodwill  and customer  contract
amortization  associated  with our DPS  acquisition is deductible for income tax
purposes  due to the  filing  of a  Internal  Revenue  Code  section  338(h)(10)
election.  Our  effective  tax rate  increased for the first nine months of 1999
over 1998  primarily due to the lower income before income taxes  resulting from
the  one-time  corporate  restructuring  charge  for  the  Minneapolis  facility
consolidation.  Excluding  this charge,  our  effective tax rate would have been
43.9% for the first nine months of 1999. The remaining increase in the effective
tax rate for the first nine months of 1999 is  primarily  due to  non-deductible
goodwill and customer contracts  amortization expense resulting from the ValueRx
acquisition  which is included in the entire nine month period for 1999 compared
to only six months in 1998.

</TABLE>

         Our net income increased  $5,692,000,  or 50.4%, and $209,000, or 0.7%,
for the third  quarter of 1999 over 1998 and for the first  nine  months of 1999
over 1998, respectively.  Net income for the nine months of 1999 was reduced due
to the following one-time charges:

o    A corporate  restructuring charge of $9,400,000 ($5,773,000 net of tax), or
     $0.16 per basic and  diluted  share for the first nine  months of 1999,  as
     discussed in "--Cost and Expenses."

o    An extraordinary loss on the early retirement of debt of $7,150,000, net of
     tax,  or $0.20 per basic and  diluted  share for the first  nine  months of
     1999. The  extraordinary  loss is associated  with  refinancing of the debt
     incurred in connection with our acquisition of ValueRx,  the refinancing of
     the  debt  incurred  in  connection  with our  acquisition  of DPS from the
     proceeds of our equity and debt  offerings,  and repayment of the debt from
     our own cash, as discussed in "Liquidity and Capital Resources" below.

         Excluding  one-time  charges,  net income for the third quarter of 1999
would have been $0.46 per basic  share and $0.45 per diluted  share  compared to
$0.34 per basic and diluted share for the third  quarter of 1998.  For the first
nine months of 1999 net income excluding  one-time charges would have been $1.08
per basic  share and $1.06 per diluted  share  compared to $0.93 per basic share
and $0.91 per diluted  share for the first nine  months of 1998.  On a pro forma
basis,  excluding  one-time  charges and assuming our equity and debt  offerings
occurred on April 1, 1999,  net income per basic and diluted share for the first
nine months of 1999 would have been $1.30 and $1.27, respectively.

Liquidity and Capital Resources

         During the first nine months of 1999,  net cash  provided by operations
decreased  $11,155,000 to $88,617,000  from $99,772,000 in 1998 primarily due to
the payment of certain  accruals  from  December  31, 1998  associated  with our
ValueRx  acquisition.  Our  investment  in  net  working  capital  significantly
decreased to  $(25,308,000)  as of September  30, 1999 from  $117,611,000  as of
December 31, 1998.  This reduction is due to the payment cycles utilized by DPS.
Claims and rebate payable  increased  $297,445,000,  or 87.9%, from December 31,
1998, while net receivables increased $223,140,000,  or 51.5%, from December 31,
1998. The inclusion of DPS reduced our days sales outstanding ("DSO") to 30 days
at September 30, 1999 from 41 days at December 31, 1998 and 40 days at September
30, 1998.  Gross  revenues must be used to calculate the days sales  outstanding
due to the  impact of the Gross  Basis  versus  the Net Basis of  recording,  as
discussed in "Overview" and "--Net  Revenues." The accounts  receivable  balance
includes the cost of the pharmaceutical dispensed,  which may not be included in
net revenues, as required by generally accepted accounting principles,  based on
the contractual terms embedded in client and pharmacy  contracts.  The following

         Our allowance for doubtful accounts has decreased $2,971,000,  or 16.7%
to $14,835,000 at September 30, 1999 from  $17,806,000 at December 31, 1998. The
decrease is primarily due to the final adjustment,  in accordance with generally
accepted accounting  principles,  to the ValueRx opening balance sheet allowance
for  doubtful   accounts  and  goodwill  based  on  the  collection  of  ValueRx
receivables. As a percentage of at risk receivables (which represent receivables
for  which  there is no  corresponding  payable),  the  allowance  for  doubtful
accounts  was 2.8% at September  30, 1999  compared to 4.3% at December 31, 1998
and 2.9% at December 31, 1997. The  percentage  reduction from December 31, 1998
to September 30, 1999 is attributable to the aforementioned  final adjustment of
the ValueRx opening balance sheet.

         During the fourth  quarter of 1999, we expect to increase our inventory
balances  to ensure  adequate  supply of  prescription  medications  at our mail
pharmacies in  anticipation  of the Year 2000.  Management  expects to primarily
fund our future debt service, inventory purchases,  integration costs, Year 2000
costs and other normal  operating cash needs  primarily with operating cash flow
or, to the extent  necessary,  with working capital  borrowings  under our $1.05
billion credit facility, discussed below.

         Our capital  expenditures  in the first nine  months of 1999  increased
$7,935,000,  or 44.1% over the first nine  months of 1998  primarily  due to our
concerted  effort to invest in  information  technology  to enhance the services
provided  to our  clients  and the  acquisition  of DPS.  We expect to  continue
investing in technology  that will provide  efficiencies  in operations,  manage
growth and  enhance the  services  provided  to our  clients.  We expect to fund
future anticipated capital  expenditures  primarily with operating cash flow or,
to the extent necessary,  from working capital borrowings under our $300 million
revolving credit facility.

         On April 1, 1999,  we executed a $1.05 billion  credit  facility with a
bank  syndicate  led by Credit  Suisse  First Boston and Bankers  Trust  Company
consisting of $750 million in term loans, including $285 million of Term A loans
and $465 million of Term B loans, and a $300 million  revolving credit facility.
As of July 1999,  the Term B loans have been paid off through net proceeds  from
our equity and senior notes  offerings  and  $74,131,000  of our own cash.  As a
result, we recorded an extraordinary charge during the third quarter of 1999 and
the first nine months of 1999 for the write-off of the deferred  financing  fees
in the amount of $553,000 net of tax and  $7,150,000  net of tax,  respectively.
The Term A loans and the revolving credit facility mature on March 31, 2005. The
credit  facility is secured by the  capital  stock 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), and is also secured by 65% of
the stock of our foreign subsidiaries.

        The  credit  facility  requires  us to  pay  interest  quarterly  on an
interest rate spread based on several London  Interbank  Offered Rates ("LIBOR")
or base rate options.  Using a LIBOR spread,  the Term A loans and the revolving
loan had an interest  rate of 7.94% on September  30,  1999.  Beginning in March
2001, we are required to make annual  principal  payments on the Term A loans of
$42,750,000  in 2001,  $57,000,000  in 2002 and  2003,  $62,700,000  in 2004 and
$65,550,000  in 2005.  The credit  facility  contains  covenants  that limit the
indebtedness  we may  incur,  dividends  paid 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,
we are required to pay an annual fee of 0.5%, payable in quarterly installments,
on the  unused  portion  of the  revolving  credit  facility  ($160  million  at
September  30, 1999).  At September  30, 1999,  we were in  compliance  with all
covenants associated with the $1.05 billion credit facility.

         Additionally,  on April 1,  1999,  we  executed a $150  million  senior
subordinated  bridge credit facility from Credit Suisse First Boston Corporation
and Bankers Trust Company. The proceeds from the bridge credit facility and $890
million in borrowings  from the credit  facility were used to consummate the DPS
acquisition,  refinance our $440 million credit facility,  of which $360 million
was outstanding, and other indebtedness and pay related fees and expenses.

         In June 1999, we completed our equity offering to sell 5,175,000 shares
of our  Class A common  stock at an  offering  price of $61 per  share.  We also
completed our $250 million 9 5/8% Senior Notes due 2009 offering under Rule 144A
of the  Securities  Act of 1933, as amended.  The Company  filed a  registration
statement,  which was  declared  effective  on August 4, 1999,  to exchange  the
privately placed Senior Notes for registered  Senior Notes on substantially  the
same terms.  The net proceeds from the equity and debt offerings of $299,381,000
and  $243,503,000,  respectively,  were used to retire the $150  million  senior
subordinated bridge credit facility plus accrued interest and repay a portion of
the Term B portion of the credit facility plus accrued interest.

         To alleviate interest rate volatility, we entered into an interest rate
swap  arrangement  for an original  notional  principal  amount of $360 million,
effective April 3, 1998,  with the First National Bank of Chicago,  a subsidiary
of Bank One  Corporation.  Under the terms of the swap,  we agreed to  receive a
floating  rate of interest on a portion of our term loans based on a three-month
LIBOR rate in  exchange  for  payment of a fixed rate of  interest  of 5.88% per
annum.  The notional  amount of the swap  amortizes,  beginning  April 1999,  in
semi-annual  installments  of $27  million,  increasing  to $36 million in April
2000,  to $45  million in April 2001 and to $48  million  in April  2002.  As of
September 30, 1999, the notional principal amount was $333 million. As a result,
we have, in effect,  converted  $333 million of our variable rate debt under the
Credit  Facility  to fixed rate debt at 5.88% per annum for the first four years
of the Credit Facility, plus the interest rate spread of 2.0%.

         On  June  17,  1999,  we  entered  into  another   interest  rate  swap
arrangement with Bankers Trust Company, effective April 17, 2000 and terminating
on April 17, 2005.  As of September  30,  1999,  there is no notional  principal
amount as the swap is not yet effective. Upon effectiveness,  the swap will have
an  initial  notional  principal  amount of $15  million  increasing  to $137.25
million in October 2002.  Beginning in April 2003, the notional principal amount
will amortize over the remaining term of the swap.  Under the terms of the swap,
we agreed to receive a floating  rate of interest on notional  principal  amount
based on a  three-month  LIBOR rate in  exchange  for payment of a fixed rate of
interest  of 6.25% per  annum.  When the swap  becomes  effective,  we will,  in
effect,  convert the notional  principal  amount of our variable rate debt under
our Credit  Facility  to fixed rate debt at 6.25% per annum,  plus the  interest
rate spread.

         As of September 30, 1999, we had  repurchased a total of 475,000 shares
of our Class A Common  Stock  under the  open-market  stock  repurchase  program
announced by us on October 25, 1996, although no repurchases occurred during the
first nine months of 1999. Our 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 we deem
appropriate  based upon prevailing  market and business  conditions,  subject to
restrictions on stock repurchases contained in our $1.05 billion credit facility
and the Indenture covering our Senior Notes.  During the quarter ended September
30, 1999, we used 10,000 shares previously  purchased under the above program to
satisfy obligations under our employee stock purchase program.

         We have reviewed and currently intend to continue  reviewing  potential
acquisitions  and  affiliation  opportunities.  We believe that  available  cash
resources,  bank  financing or the issuance of additional  common stock could be
used to finance such  acquisitions  or  affiliations.  However,  there can be no
assurance we will make other acquisitions or affiliations in 1999 or thereafter.

Other Matters

          On August 31, 1999, Express Scripts,  Inc., and  YourPharmacy.com,
Inc.  ("YPC"),  a wholly owned  subsidiary of Express  Scripts,  entered into an
Asset Contribution and Reorganization  Agreement (the "Contribution  Agreement")
with PlanetRx.com,  Inc. ("PlanetRx"),  PRX Holdings, Inc. ("Holdings"), and PRX
Acquisition Corp.  ("Acquisition Sub"). Pursuant to the Contribution  Agreement,
YPC agreed to contribute  certain  operating assets  constituting its e-commerce
business in prescription and  non-prescription  drugs and health and beauty aids
to Holdings in exchange for 19.9% of the  post-initial  public  offering  common
equity  of  Holdings  (the  "IPO"),  and  PlanetRx  was also to  assume  certain
obligations of YPC. Simultaneously with this transaction, Acquisition Sub was to
merge into PlanetRx and PlanetRx  shareholders  would receive stock in Holdings,
which  would  change  its  name  to  "PlanetRx.com  Inc."  As a  result  of  the
transactions,  YPC would be a 19.9%  shareholder  in the new PlanetRx  (formerly
Holdings), which would conduct business as an internet pharmacy.

     On  October  13,  1999,  the  transactions  described  in the  Contribution
Agreement were  consummated,  YPC received  10,369,990  shares, or 19.9%, of the
common equity of PlanetRx, and PlanetRx assumed options granted to YPC employees
which  converted  into options to purchase  approximately  1.8 million shares of
PlanetRx common stock. The consummation of the transaction  occurred immediately
preceding the closing of PlanetRx's IPO of common stock.  Based on the IPO price
of $16 per  share,  YPC  received  consideration  valued at  approximately  $166
million.  We will record a one-time after tax gain of approximately $101 million
on the  transaction,  and a  one-time  after tax stock  compensation  expense of
approximately $12 million relating to the employee stock options.

         Also on August 31, 1999, Express Scripts entered into an Agreement with
PlanetRx  pursuant to which Express Scripts has,  subject to certain  exceptions
set forth therein, designated PlanetRx as its exclusive internet pharmacy in the
United  States  for a term of five  years,  with a right to  participate  in its
pharmacy network for ten years.  Under the Agreement,  customers who are covered
under an Express  Scripts  pharmacy  benefit plan will generally be able to fill
prescriptions at PlanetRx's website and will be entitled to receive the benefits
of the coverage under the Express Scripts  pharmacy  benefit plan. The Agreement
also provides for various  co-operative  marketing activities by Express Scripts
and PlanetRx. Pursuant to this Agreement, PlanetRx will make certain payments to
Express Scripts annually over the term of the Agreement,  with a minimum payment
obligation of $11,650,000 annually for five years, plus reimbursement of certain
expenses,  with a potential five year extension (subject to certain conditions),
plus  an  incremental  fee  based  on  Express  Scripts'  members'  activity  on
PlanetRx's  website.  Express Scripts has committed to exclusively  co-brand and
co-market  PlanetRx as Express Scripts's online pharmacy.  Co-branding  includes
but is not limited to placing  PlanetRx's name, logo and other information about
PlanetRx  on  Express  Scripts'  website  and  marketing  and  sales  materials.
Co-marketing  includes  Express Scripts  promoting  PlanetRx as Express Scripts'
online  pharmacy  in  Express  Scripts'  marketing  and  sales  activities.  The
Agreement became effective on October 13, 1999. The Agreement contains customary
termination,   default   and   indemnification   provisions.   As  part  of  the
relationship,  PlanetRx agreed to certain exclusivity  provisions that precludes
it from directly or indirectly operating as a pharmacy benefit manager.

         In June 1998,  Statement of Financial  Accounting  Standards  Statement
133,  Accounting for Derivative  Instruments and Hedging  Activities ("FAS 133")
was issued.  FAS 133 requires all  derivatives to be recognized as either assets
or  liabilities  in the  statement  of  financial  position and measured at fair
value.  In addition,  FAS 133 specifies the  accounting  for changes in the fair
value  of a  derivative  based on the  intended  use of the  derivative  and the
resulting  designation.  The effective date for FAS 133 was originally effective
for all fiscal quarters of fiscal years beginning after June 15, 1999.  However,
the Financial Accounting Standards Board has deferred the effective date so that
it will begin for all fiscal  quarters of fiscal years  beginning after June 15,
2000,  and will be  applicable  to our first  quarter of fiscal  year 2001.  Our
present  interest rate swap (see  "--Liquidity  and Capital  Resources") will be
considered a cash flow hedge.  Accordingly,  the change in the fair value of the
swap  will 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 our underlying variable rate debt. If we had adopted FAS
133 as of September  30, 1999,  we would have  recorded the  unrealized  gain of
$2,600,000  as  an  asset  and  increase  in  stockholders'   equity  and  other
comprehensive income.

Year 2000

         Our operations rely heavily on computers and other information  systems
technologies.  In 1995, we began addressing the "Year 2000" issue,  which refers
to the  inability of certain  computer  systems to properly  recognize  calendar
dates beyond  December 31, 1999.  This arises as a result of systems having been
programmed with two digits rather than four digits to define the applicable year
in  order  to  conserve  computer  storage  space,   reduce  the  complexity  of
calculations  and produce  better  performance.  The two-digit  system may cause
computers to interpret  the year "00" as "1900" rather than as "2000," which may
cause  system   failures  or  produce   incorrect   results  when  dealing  with
date-sensitive information beyond 1999.

         We formed a Year 2000 task force to address this issue.  The task force
has performed a self-assessment and developed a compliance plan that addresses:

o    internally developed application software
o    vendor developed application software
o    operating system software
o    utility software
o    vendor/trading partner-supplied files
o    externally provided data or transactions
o    non-information technology devices that are material to our business
o    adherence to applicable industry standards.

         Our plan  covers  the  traditional  Express  Scripts,  ValueRx  and DPS
systems.  Progress in each area is monitored  and  management  reports are given
periodically.

         We have various  applications and operating systems that are considered
critical to our operations. These systems have been successfully tested by us in
an integrated  environment for Year 2000 readiness.  Testing of the applications
and  operating  systems  includes  the  adjudication  process,  the  eligibility
process, the billing and remittance process,  the communication  process and the
reporting process,  including  financial  reporting.  In addition,  beginning in
1995, new internally developed software has been developed to be Year 2000 ready
and will be fully tested during the remainder of 1999.

         We are participating in a joint effort with other PBMs, retail pharmacy
chains,  transaction routing companies and adjudication software vendors to test
Year  2000  readiness  in the  industry.  The joint  effort  is called  the "Y2K
Provider & Vendor Testing  Coalition"  and is being  facilitated by The National
Health Information  Network.  The coalition has the support of major U.S. retail
pharmacies,  including  American  Stores,  CVS, Eckerd,  Rite-Aid,  Wal-Mart and
Walgreens.  The inclusion of transaction  routing vendors and software companies
could permit up to 95% of our pharmacy  network to be tested (although there can
be no assurance  that all parties who are invited to  participate  will actually
participate).  The program  allocates  the retail  pharmacy  chains and software
vendors  among the various  PBMs who will be required to test the  vendors'  and
pharmacy  chains' Year 2000  compliance.  We successfully  completed the testing
during the third quarter of 1999.

         We have identified and communicated with critical  suppliers to confirm
their Year 2000 readiness.  Approximately 85% of critical vendors have responded
their  intention  to be  ready by the end of the  third  quarter.  We have  also
contacted several hundred clients and several thousand pharmacies whose computer
systems  appear  to us not to be  Year  2000  ready  in an  effort  to  increase
awareness  of the  problem and  minimize or  eliminate  any  disruption  in data
transfer  activity  between any of these parties and us. We have  developed date
windowing  logic,  which  forces an entry into the  century  field of a computer
application  if one is not  provided by the user,  which we believe will address
many issues concerning retail pharmacies and clients with non-ready systems. Due
to our  contracts  typically  extending  over  several  years and our receipt of
member  eligibility  information from clients that reflect dates beyond the Year
2000, we have been receiving  information  that would identify certain Year 2000
issues for several  years.  Any problems we have  encountered  to date have been
rectified by the client or, if necessary, by us using our windowing logic. There
can be no assurance, however, that all of these problems that may be encountered
in the future can be rectified with the windowing logic.

         In addressing  the Year 2000 issue,  we have and will continue to incur
internal staff costs as well as external  consulting and other expenses  related
to  infrastructure  enhancements.  As of  September  30,  1999 we have  incurred
approximately  $4,400,000,   excluding  costs  incurred  by  DPS  prior  to  our
acquisition,  which were funded by SmithKline Beecham,  addressing the Year 2000
issue.  We  anticipate  spending an additional  $250,000 to $375,000  during the
remainder of 1999  addressing the Year 2000 issue.  All  expenditures  are being
expensed  as  incurred.  To date,  these  costs have not had a material  adverse
effect on our results of operations or financial condition, and are not expected
to have a  material  adverse  effect on our  future  results  of  operations  or
financial condition.

         In connection  with our  acquisition of DPS, we performed  certain Year
2000 due diligence and received  representations that DPS had implemented a Year
2000  plan  for  upgrading  its  computer  systems  and  communicated  with  its
vendors/trading partners regarding their respective Year 2000 compliance.  Based
on our due  diligence  and the  representations  we received,  we believe  DPS's
critical  applications and operating systems have been  successfully  tested for
Year 2000  compliance.  However,  the DPS systems are scheduled for another Year
2000 test during November 1999.

         We believe that, with appropriate  modifications  to existing  computer
systems,  updates by vendors and trading partners and conversion to new software
in the  ordinary  course of our  business,  the Year 2000 issue is not likely to
pose significant  operational  problems for us. However,  if the above-described
conversions  are not  completed  in a proper and timely  manner by all  affected
parties,   or  if  our  logic  for  communicating   with  non-ready  systems  is
ineffective,  the Year 2000 issue could result in material  adverse  operational
and financial  consequences to us. There can be no assurance that our efforts or
those of our vendors and trading partners,  who are beyond our control,  will be
successful in addressing the Year 2000 issue.

         We have  formalized  our  contingency  plans to address  potential Year
2000-related  disruptions and risks,  including risks of vendor/trading  partner
non-readiness,  as well as non-readiness of any of our critical operations.  All
departments have submitted  contingency  plans for formal review and approval by
our internal audit  department.  The contingency plan addresses the processes to
be performed should our electronic systems fail, staffing  requirements,  client
and pharmacy communications.  However, our contingency plans will modified as we
continue testing and receive updates from vendor/trading  partners. In addition,
there can be no assurance that our contingency plans will  successfully  address
all potential circumstances or consequences.

Impact of Inflation

         Changes  in  prices  charged  by  manufacturers   and  wholesalers  for
pharmaceuticals  affect our net revenues  and cost of revenues.  To date we have
been able to recover  price  increases  from our clients  under the terms of our
agreements,  although under selected  arrangements in which we have  performance
measurements  on drug costs with our clients we could be  adversely  affected by
inflation in drug costs if the result is an overall  increase in the cost of the
drug plan to the client. To date, changes in pharmaceutical  prices have not had
a significant adverse effect on us.

Market Risk

         To alleviate interest rate volatility, we entered into an interest rate
swap  arrangement  for an original  notional  principal  amount of $360  million
effective  April 3, 1998,  with First National Bank of Chicago,  a subsidiary of
Bank One  Corporation.  Under  the swap  arrangement,  we  agreed  to  receive a
floating  rate of  interest on an amount  equal to a portion of the  outstanding
principal  balance  of our term  loans  based  on a  three-month  LIBOR  rate in
exchange  for  payment  of a fixed rate of  interest  of 5.88% per annum on such
amount. The weighted average variable rate received by us for the period January
1, 1999 to  September  30,  1999,  was 5.13%.  The  notional  amount of the swap
amortizes,  beginning in April 1999, in semi-annual installments of $27 million,
increasing to $36 million in April 2000, to $45 million in April 2001 and to $48
million in April 2002. As of September 30, 1999, the notional amount of the swap
was $333 million.  The swap expires on April 3, 2003. At September 30, 1999, the
fair value of the swap was $1,238,000.

         On  June  17,  1999,  we  entered  into  another   interest  rate  swap
arrangement with Bankers Trust Company, effective April 17, 2000 and terminating
on April 17, 2005.  As of September  30,  1999,  there is no notional  principal
amount as the swap is not yet effective. Upon effectiveness,  the swap will have
an  initial  notional  principal  amount of $15  million  increasing  to $137.25
million in October 2002.  Beginning in April 2003, the notional principal amount
will amortize over the remaining term of the swap.  Under the terms of the swap,
we agreed to receive a floating  rate of interest on notional  principal  amount
based on a  three-month  LIBOR rate in  exchange  for payment of a fixed rate of
interest of 6.25% per annum.  At September 30, 1999, the fair value of the swap
was $1,362,000.

         Interest  rate risk is  monitored  on the basis of  changes in the fair
value and a sensitivity  analysis is used to determine the impact  interest rate
changes will have on the fair value of the interest  rate swaps,  measuring  the
change in the net present  value  arising from the change in the interest  rate.
The fair value of the swaps are then determined by calculating the present value
of all cash-flows expected to arise thereunder, with future interest rate levels
implied from prevailing mid-market yields for money-market instruments, interest
rate futures and/or prevailing mid-market swap rates. Anticipated cash-flows are
then  discounted on the  assumption of a  continuously  compounding  zero-coupon
yield curve.  A 10 basis point decline in interest  rates at September 30, 1998,
would  have  caused  the fair  value of the  swaps to  decrease  by  $3,171,000,
resulting in a fair value of $(1,933,000).

Item 3.       Quantitative and Qualitative Disclosures About Market Risk

         Response to this item is included  in Item 2  "Management's  Discussion
and  Analysis of Financial  Condition  and Results of  Operations--Market  Risk"
above, and incorporated by reference herein.



                           PART II. OTHER INFORMATION


Item 1.       Legal Proceedings

         As discussed in detail in the Company's  Quarterly  Report on Form 10-Q
for the period  ended June 30,  1998,  filed with the  Securities  and  Exchange
Commission on August 13, 1998 (the "Second Quarter 10-Q"),  the Company acquired
all of  the  outstanding  capital  stock  of  Value  Health,  Inc.,  a  Delaware
corporation  ("VHI"),  and  Managed  Prescription  Network,   Inc.,  a  Delaware
corporation ("MPN") from Columbia  HCA/HealthCare  Corporation  ("Columbia") and
its  affiliates  on April 1, 1998 (the  "Acquisition").  VHI,  MPN and/or  their
subsidiaries  (collectively,  the  "Acquired  Entities"),  were party to various
legal proceedings,  investigations or claims at the time of the Acquisition. The
effect of these actions on the Company's 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. A brief update of the most notable of the proceedings
follows:

         As  discussed  in detail in the  Second  Quarter  10-Q,  the  Company's
Quarterly  Report on Form 10-Q for the period ended  September  30, 1998,  filed
with the Securities and Exchange  Commission on November 16, 1998, the Company's
Annual  Report on Form 10-K/A for the year ended  December 31, 1998,  filed with
the  Securities  and Exchange  Commission  on June 10, 1999,  and the  Company's
Quarterly  Report on Form 10-Q for the period ended March 31,  1999,  filed with
the  Securities  and Exchange  Commission  on May 14,  1999,  VHI and one of its
subsidiaries  are party to two securities  litigation  matters,  Bash, et al. v.
Value Health, Inc., et al., No. 3:97cv2711 (JCH) (D.Conn.), and Freedman, et al.
v.  Value  Health,  Inc.,  et al.,  No.  3:95 CV 2038  (JCH)  (D.Conn).  The two
lawsuits, filed in 1995, allege that VHI and certain other defendants made false
or misleading  statements to the public in connection with VHI's  acquisition of
Diagnostek,  Inc. in 1995, and in connection  with one of VHI's  contracts.  The
Bash lawsuit also alleges  false or  misleading  statements  by  Diagnostek  and
certain of its former officers and directors  concerning its financial condition
prior to the  merger  with  VHI.  On  April  24,  1998,  the two  lawsuits  were
consolidated.

         On February 18, 1999, the court granted  plaintiffs'  motions for class
certification  and certified a class consisting of (i) all persons who purchased
or  otherwise  acquired  shares of VHI  during  the  period  from April 3, 1995,
through and  including  November 7, 1995,  including  those who acquired  shares
issued in  connection  with the  Diagnostek  merger;  and (ii) all  persons  who
purchased  or otherwise  acquired  shares of  Diagnostek  during the period from
March 27,  1995,  through and  including  July 28, 1995.  Fact  discovery in the
consolidated  lawsuit is complete.  The parties are awaiting an order on motions
to dismiss the Bash lawsuit filed by  Diagnostek  and its former  officers.  The
parties are also awaiting an order from the court  regarding  the  scheduling of
expert discovery and dispositive motions.

         In connection with the  Acquisition,  Columbia has agreed to defend and
hold the Company and its  affiliates  (including  VHI) harmless from and against
any  liability  that may  arise  in  connection  with  either  of the  foregoing
proceedings.  Consequently,  the  Company  does not  believe  it will  incur any
material liability in connection with the foregoing matters.

         The Company is a named defendant in Allcare Health  Management  System,
Inc. v. Cerner  Corporation,  et al., No.  499-CV-0464-Y  (N.D.  TX).  Plaintiff
Allcare Health Management System,  Inc.,  commenced this action on or about June
11, 1999, alleging, inter alia, that the named defendants, including the Company
and its wholly-owned subsidiary, Diversified Pharmaceutical Services, Inc., were
infringing upon U.S. Patent No. 5,301,105  entitled "All Care Health  Management
System" which is generally  directed to an integrated and  comprehensive  health
management  system.  As the case was just  recently  commenced,  and involves at
least thirteen parties,  no discovery schedule has yet been ordered by the Court
and  only  minimal  discovery  has been  conducted  by one  third-party  and the
plaintiff to date.  The Company  intends to vigorously  contest the  plaintiff's
allegations of infringement as well as the alleged  validity and  enforceability
of the patent in suit.

Item 4.       Submission of Matters to a Vote of Security Holders

         On September  17, 1999,  the Company  initiated a consent  solicitation
seeking  approval of an amendment to the Indenture  governing its $250 million 9
5/8% Senior Notes due 2009 (the "Notes"), in connection with its contribution of
certain assets of its wholly-owned subsidiary,  YourPharmacy.com,  Inc. ("YPC"),
to PlanetRx.com,  Inc.  ("PlanetRx")  (see Item 2 - Management's  Discussion and
Analysis of Financial  Condition  and Results of  Operations  - Other  Matters).
Specifically,  the proposed  amendment to the  Indenture  would  modifiy (i) the
definition  of Asset  Disposition  contained  therein to permit  the  Company to
transfer the specified  assets of YPC without  restriction  under the Asset Sale
Covenant  contained  therein , and (ii) the definition of Permitted  Investments
contained  therein  to make the  PlanetRx  stock  which the  Company  received a
Permitted  Investment.  The consent  solicitation expired on September 30, 1999,
and the proposed  amendment was approved by the  affirmative  vote of holders of
97.168%,  or  $242,920,000,  of the  aggregate  principal  amount  of the  Notes
outstanding.  A copy of the Supplemental  Indenture containing the amendments is
filed as Exhibit 4.4 hereto.

     AMENDMENT  NO. 2  ("Amendment  No. 2") dated as of August  16,  1999 to the
Credit  Agreement  dated as of April 1, 1999  (the  "Credit  Agreement"),  among

the Lenders  party  thereto;  Credit  Suisse  First  Boston,  as Lead  Arranger,
Administrative Agent and Collateral Agent; Bankers Trust Company, as Syndication
Agent;  The First  National  Bank of Chicago,  as  Co-Documentation  agent;  and
Mercantile  Bank,  N.A.,  as  Co-Documentation   agent  (capitalized  terms  not
otherwise defined in this Amendment No. 2 have the same meaning assigned to such
terms in the Credit Agreement).

                              W I T N E S S E T H :

     WHEREAS,  pursuant  to  Section  10.6 of the Credit  Agreement,  all of the
Lenders hereby agree to amend certain  provisions of the Credit Agreement as set
forth herein;

     NOW, THEREFORE,  in consideration of the foregoing,  and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereto hereby agree as follows:

     SECTION ONE - Amendment.  Section  10.6A of the Credit  Agreement  shall be
amended  by  deleting  the first  sentence  thereof  and  replacing  it with the
following:

     "No amendment, modification, termination or waiver of any provision of this
Agreement or of the Notes, and no consent to any departure by Company therefrom,
shall in any event be  effective  without the written  concurrence  of Requisite
Lenders; provided that any such amendment, modification,  termination, waiver or
consent which:  reduces the principal amount of any of the Loans; changes in any
manner  the  definition  of "Pro Rata  Share" or the  definition  of  "Requisite
Lenders";  changes in any manner any provision of this Agreement  which,  by its
terms, expressly requires the approval or concurrence of all Lenders;  postpones
the scheduled  final  maturity date of any of the Loans (but not the date of any
scheduled installment of principal); postpones the date on which any interest or
any fees are  payable;  decreases  the  interest  rate borne by any of the Loans
(other than any waiver of any increase in the interest rate applicable to any of
the  Loans  pursuant  to  subsection  2.2E) or the  amount  of any fees  payable
hereunder;   increases  the  maximum  duration  of  Interest  Periods  permitted
hereunder; reduces the amount or postpones the due date of any amount payable in
respect of any Letter of Credit;  extends the  required  expiration  date of any
Letter of Credit beyond the Revolving  Commitment  Termination Date;  changes in
any manner the obligations of Lenders relating to the purchase of participations
in Letters of Credit; releases any Lien granted in favor of Administrative Agent
with  respect  to all or  substantially  all of  the  Collateral;  releases  any
Subsidiary Guarantor from its obligations under the Subsidiary Guaranty, in each
case other than in accordance  with the terms of the Loan  Documents  (provided,
Express  Online Inc.  (Your.Pharmacy.com)  shall be released from the Subsidiary
Guaranty  executed by it on the Closing  Date on such date as the Company  shall
sell any or all of the capital stock of such Subsidiary  Guarantor);  or changes
in any manner the provisions contained in subsection 8.1 or this subsection 10.6
shall be effective  only if evidenced by a writing signed by or on behalf of all
Lenders; provided, further, that no such amendment,  modification,  termination,
waiver or consent  shall  increase the  Commitments  of a Lender over the amount
hereof then in effect  without the consent of such  Lender;  provided,  further,
that if any  matter  described  in the first  proviso of this  subsection  10.6A
relates only to (a) all Term Loans,  the  approval of all Term Lenders  shall be
sufficient,  (b) Tranche A Term Loans or Tranche B Term  Loans,  as the case may
be,  the  approval  of all of the  Lenders  of the  affected  Term Loan shall be
sufficient;  and (c) a Revolving Loan or Revolving Loan Commitment, the approval
of all  Revolving  Lenders  shall be  sufficient."  SECTION TWO - Conditions  to
Effectiveness.  This Amendment No. 2 shall become effective as of the date first
above written when, and only when, the Administrative  Agent shall have received
counterparts  of this  Amendment No. 2 executed by the Company,  the  Subsidiary
Guarantors  and  all of the  Lenders  or,  as to  any  of  the  Lenders,  advice
satisfactory  to the  Administrative  Agent that such Lender has  executed  this
Amendment No. 2. The  effectiveness of this Amendment No. 2 (other than Sections
Five and Seven hereof) is conditioned  upon the accuracy of the  representations
and warranties set forth in Section Three hereof.

     SECTION  THREE -  Representations  and  Warranties.  In order to induce the
Lenders  and the  Agents  to enter  into  this  Amendment  No.  2,  the  Company
represents  and warrants to each of the Lenders and the Agents that after giving
effect to this  Amendment No. 2, (i) no Default or Event of Default has occurred
and is  continuing;  and (ii) all of the  representations  and warranties in the
Credit  Agreement,  after giving  effect to this  Amendment  No. 2, are true and
complete in all material respects on and as of the date hereof as if made on the
date hereof (or, if any such  representation  or warranty is expressly stated to
have been made as of a specific date, as of such specific date).

     SECTION  FOUR -  Reference  to and Effect on the Credit  Agreement  and the
Notes. On and after the effectiveness of this Amendment No. 2, each reference in
the Credit Agreement to "this Agreement", "hereunder", "hereof" or words of like
import referring to the Credit Agreement and each reference in each of the other
Credit Documents to the "Credit Agreement",  "thereunder", "thereof" or words of
like import referring to the Credit Agreement,  shall mean and be a reference to
the Credit Agreement,  as amended by this Amendment No. 2. The Credit Agreement,
the Notes and each of the other Credit  Documents,  as  specifically  amended by
this  Amendment No. 2, are and shall continue to be in full force and effect and
are hereby in all respects ratified and confirmed.

     SECTION  FIVE - Costs,  Expenses and Taxes.  The Company  agrees to pay all
reasonable  costs and expenses of the Agents in connection with the preparation,
execution  and delivery of this  Amendment No. 2 and the other  instruments  and
documents to be delivered hereunder, if any (including,  without limitation, the
reasonable  fees and expenses of Cahill Gordon & Reindel) in accordance with the
terms of Section 10.2 of the Credit  Agreement.  In addition,  the Company shall
pay or reimburse  any and all stamp and other taxes  payable or determined to be
payable in connection  with the  execution and delivery of this  Amendment No. 2
and the other instruments and documents to be delivered  hereunder,  if any, and
agrees to save each Agent and each Lender  harmless from and against any and all
liabilities with respect to or resulting from any delay in paying or omission to
pay such taxes.

     SECTION  SIX -  Execution  in  Counterparts.  This  Amendment  No. 2 may be
executed  in any  number of  counterparts  and by  different  parties  hereto in
separate  counterparts,  each of which when so executed shall be deemed to be an
original and all of which taken together  shall  constitute but one and the same
agreement.  Delivery of an  executed  counterpart  of a  signature  page to this
Amendment  No. 2 by  telecopier  shall be  effective  as  delivery of a manually
executed counterpart of this Amendment No. 2.

     SECTION SEVEN - Governing  Law. This  Amendment No. 2 shall be governed by,
and construed and enforced in accordance with, the internal laws of the State of
New York (including  Section 5-1401 of the General  Obligations Law of the State
of New York),  without  giving  effect to any  provisions  thereof  relating  to

     IN WITNESS WHEREOF,  the parties hereto have caused this Amendment No. 2 to
be executed by their respective  officers  thereunto duly authorized,  as of the
date first above written.

                           AMENDMENT NO. 3 AND WAIVER


     AMENDMENT NO. 3 AND WAIVER  ("Amendment No. 3") dated as of October 7, 1999
to the  Credit  Agreement  dated as of April 1, 1999 (the  "Credit  Agreement"),
among Express  Scripts,  Inc.; each of the Subsidiary  Guarantors party thereto;
each of the Lenders party thereto; Credit Suisse First Boston, as Lead Arranger,
Administrative Agent and Collateral Agent; Bankers Trust Company, as Syndication
Agent;  The First  National  Bank of Chicago,  as  Co-Documentation  agent;  and
Mercantile  Bank,  N.A.,  as  Co-Documentation   agent  (capitalized  terms  not
otherwise defined in this Amendment No. 3 have the same meaning assigned to such
terms in the Credit Agreement).

                              W I T N E S S E T H :

     WHEREAS,  Company  has  informed  Lenders  that it  intends to enter into a
series  of   transactions   pursuant   to  which,   among  other   things,   (i)
yourPharmacy.com,  Inc.  ("yourPharmacy.com")  would transfer certain  specified
assets to  PlanetRx.com,  Inc.  ("PlanetRx")  in  exchange  for common  stock in
PlanetRx,  and (ii)  Company and  PlanetRx  would enter into an  agreement  (the
"Internet Pharmacy  Agreement")  detailing the ongoing  relationships  among the
parties, all as more further described on Annex I hereto;

     WHEREAS,  pursuant to Section 10.6 of the Credit  Agreement,  the Requisite
Lenders  hereby  agree  to  amend  or waive  certain  provisions  of the  Credit
Agreement as set forth herein;

     NOW, THEREFORE,  in consideration of the foregoing,  and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereto hereby agree as follows:

     SECTION ONE - Amendments. (a) The definition of "Asset Sale "in Section 1.1
of the Credit  Agreement  shall be deleted in its entirety and replaced with the
following:

     "Asset  Sale" means the sale by Company or any of its  Subsidiaries  to any
Person other than Company or any of its Wholly Owned  Subsidiaries of (i) any of
the stock of any of Company's Subsidiaries, (ii) substantially all of the assets
of any division or line of business of Company or any of its Subsidiaries (other
than the sale of assets contemplated in the PlanetRx Transactions), or (iii) any
other  assets  (whether  tangible  or  intangible)  of  Company  or  any  of its
Subsidiaries  (other than (a) inventory sold in the ordinary  course of business
(b) the Exempt  PlanetRx  Stock and (c) any such other assets to the extent that
the  aggregate  value of such assets sold in any single  transaction  or related
series of  transactions  is equal to $500,000  or less);  provided,  that,  with
respect to any sale that would be otherwise deemed an Asset Sale pursuant to the
foregoing,  if Company shall deliver an Officers'  Certificate to Administrative
Agent at or prior to receipt of proceeds of such sale  setting  forth  Company's
intent to use such proceeds to replace Plant Assets that are the subject of such
sale with other  Plant  Assets  necessary  or  desirable  for the conduct of its
business, or to exchange Plant Assets for other Plant Assets used in the conduct
of its  business,  within  180 days of such  receipt  and no Event of Default or
Potential  Event of Default  shall have occurred and shall be continuing at such
time,  such sale shall not be deemed to constitute an Asset Sale,  except to the
extent such Plant Assets or proceeds thereof are not so used within such 180-day
period,  after which time such sale,  to such  extent,  shall be deemed an Asset
Sale.

     (b) The definition of "Permitted Acquisitions" in Section 1.1 of the Credit
Agreement shall be deleted in its entirety and replaced with the following:

     "Permitted Acquisitions" means the acquisition of stock or other assets for

                    Description of the PlanetRx Transactions

                               PLANETRX.COM, INC.
                                       and
                              EXPRESS SCRIPTS, INC.

                         Summary Outline of Equity Terms


Parties:

                    PlanetRx.com,  Inc.  ("PlanetRx  I"), a newly formed  entity
               which  changes its name to  PlanetRx.com,  Inc.  ("PlanetRx  II")
               after completion of the Section 351 transaction  described below,
               Express    Scripts,    Inc.    ("ESI")   and   its    subsidiary,
               YourPharmacy.com, Inc. ("YPC")

Transactions:

                    (i)  YPC,  ESI,  PlanetRx  I and  PlanetRx  II  engage  in a
               transaction  governed by Section 351 of the Internal Revenue Code
               of 1986, as amended,  whereby ESI contributes selected assets and
               liabilities  (schedule of assets and  liabilities to be developed
               by ESI and  subject to approval of PlanetRx I) to PlanetRx II and
               PlanetRx I merges into  PlanetRx  II (with  PlanetRx II being the
               survivor),  or other similar  structure such that the transaction
               is tax  deferred  for ESI.  ESI  would  receive  common  stock in
               PlanetRx  II equal to 19.9%  (post-transaction  and  post-initial
               public offering ("IPO")) of the fully diluted equity interests in
               PlanetRx  II. The former YPC assets that would be retained by ESI
               would  be (a) all  rights  to the  names  "yourPharmacy.com"  and
               DrugDigest.org, including all derivations thereof, (b) all rights
               to the YPC website and the DrugDigest.org website,  including the
               URLs, and (c) all rights to develop,  alter,  etc. such sites and
               all YPC and DrugDigest technology;  provided the YPC site will be
               linked to the  PlanetRx  website  and all  customers  who wish to
               place an order will be transferred to the PlanetRx website.

                    (ii)  PlanetRx II shall employ and grant options to selected
               former YPC employees at closing  under its employee  stock option
               plan.

Registration
Rights:

                    ESI would have two demand registrations and unlimited "piggy
               back" registrations;  provided that the registration rights would
               be no less than  that  given to the  Series A, B and C  Preferred
               shareholders.

Consummation of
Transaction:

                    The transactions  shall be consummated  simultaneously  with
               the  consummation  of  PlanetRx  II's  IPO.  If  said  IPO is not
               consummated  within  4  months  of the  execution  of  definitive
               transaction  documentation,  all  agreements  between the parties
               with respect to the subject matter hereof shall, at ESI's option,
               be rendered  null and void,  provided  PlanetRx I shall pay ESI a
               termination fee equal to $10,000,000.

                    Board  Representation:  So long  as ESI  owns,  directly  or
               indirectly,  more  than  5%  of  the  outstanding  common  equity
               interests in PlanetRx II, ESI shall be entitled to have one Board
               seat on the PlanetRx II Board.

Regulatory
Approvals:

                    The transaction is conditioned upon receipt of any necessary
               regulatory    approvals,    including    clearance    under   the
               Hart-Scott-Rodino   Antitrust   Improvements   Act  of  1976,  if
               necessary.

Boardand Other
Approvals:

                    Notwithstanding  anything to the contrary  contained herein,
               all terms and conditions of the transactions described herein are
               expressly  subject to the receipt of  approval by the  respective
               Boards of  Directors  of ESI,  YPC and  PlanetRx I, in their sole
               discretion,  and in the case of ESI/YPC,  to satisfactory tax and
               accounting  review  of  the  proposed  transactions  contemplated
               hereby, and, in the case of PlanetRx I, approval of the Series A,
               B and C  Preferred  Shareholders,  if  necessary.  All  terms and
               conditions  are also subject to the approval of ESI's lenders and
               release  by  ESI's  lenders  of  YPC  as  a  guarantor  of  ESI's
               indebtedness,   and   review  and   receipt  of  a   satisfactory
               recommendation  by ESI's investment  banking  representative,  in
               ESI's sole discretion.


                               PLANETRX.COM, INC.
                                       and
                              EXPRESS SCRIPTS, INC.

                       Summary Outline of Agreement Terms


Parties:

PlanetRx.com, Inc. ("PlanetRx") and Express Scripts, Inc. ("ESI")

Transaction:

               (i) ESI and  PlanetRx  enter into a 5 year  extendible  agreement
          (the  "Agreement")  pursuant to which ESI grants PlanetRx the right to
          be the exclusive "internet pharmacy" in its networks in the U.S.

               (ii) ESI will not,  directly  or  indirectly,  own or  operate an
          internet  pharmacy  and  will  not  co-market  with  another  internet
          pharmacy,  or traditional  pharmacy  provider which utilizes  internet
          capabilities  for  order/reorder  and mail delivery during the term of
          the  Agreement,  except for its  ownership  interest in  PlanetRx  and
          activities described in the Agreement.

               (iii)  Other  terms of the  Agreement  shall  be as set  forth on
          Attachment I hereto.

Compensation/Fees:

               (i) Membership Fee to ESI.  PlanetRx shall pay ESI a base fee and
          an incremental fee (collectively,  the "Membership Fee"), in quarterly
          installments, based on the schedule attached hereto as Attachment II.

               (ii)Order Fee to PlanetRx.  ESI shall continue to fill all 90 day
          prescriptions for its members, and shall pay PlanetRx an Order Fee, as
          a  result  of the  savings  achieved  by ESI  due to (i)  the  on-line
          ordering  process,  and (ii)  economies of scale  realized by ESI. The
          Order  Fee shall be based on  volume  and the  level of ESI  formulary
          compliance and shall be paid for each 90 day  prescription  ordered by
          an ESI member  through  PlanetRx and  dispensed by ESI.  PlanetRx will
          remit all copayments collected to ESI.

               (iii)  Transfer  Pricing/Reimbursement  Rates  to  PlanetRx.  The
          transfer  pricing/reimbursement  rates (i.e., rates at which ESI shall
          pay  PlanetRx)  for 30 day  prescriptions  dispensed to ESI members by
          PlanetRx  shall be based on a discount  off of the  average  wholesale
          price plus a nominal fee.

Effectiveness of
Agreement:

                    The  Agreement  shall take  effect  simultaneously  with the
               consummation  of  PlanetRx's  IPO  and  the  consummation  of the
               Section 351  Transaction  (as defined below) between the parties.
               If said IPO is not  consummated  within 4 months of the execution
               of definitive transaction  documentation,  all agreements between
               the parties with respect to the subject  matter hereof shall,  at
               ESI's option, be rendered null and void.

Term:

                    The Agreement shall have an initial term of 5 years, and ESI
               shall  have the  option to extend  the term for an  additional  5
               years on the same  terms and  conditions  provided  ESI  achieves
               certain performance  benchmarks.  In addition,  PlanetRx shall be
               included in ESI's pharmacy  network(s) for a period of ten years,
               assuming consent of the plan sponsors.

ESI Internet Needs:

                    ESI will develop its own e-commerce  functionality which may
               support (i) its call center operations, (ii) account information,
               (iii) the  DrugDigest.org  site, (iv) a pharmacy locator service,
               (v) its disease management programs, (vi) its newsletters,  (vii)
               other  PBM  related  services,  and  (viii)  connectivity  to the
               PlanetRx site.  PlanetRx will pay $3  million/year to ESI to fund
               such activities by ESI throughout the term of the Agreement.  ESI
               shall establish a committee,  to which PlanetRx shall be entitled
               to appoint one member, which shall oversee such activities.

Co-Marketing
Effort:

                    ESI and PlanetRx will develop a co-marketing  plan and agree
               to  the  level  of  resources  each  will  commit.   The  general
               parameters of the plan will be as follows:

                    ESI will  promote  PlanetRx  on its YPC website and link the
               YPC site to the PlanetRx  site, and PlanetRx will promote the YPC
               website and link the PlanetRx site to the YPC site

                    Client/member materials will indicate that PlanetRx is ESI's
               internet  pharmacy provider (some plan sponsors have the right to
               approve the form and content of  communications to their members,
               so these materials may be subject to client review and approval)

                    PlanetRx  will  market  to ESI  members  (form  and  content
               subject to ESI review and approval)


PlanetRx Relationship
With  Other  PBMs:

                    ESI will be  PlanetRx's  premier/preferred  PBM  partner and
               will be  designated as such on the PlanetRx  site.  PlanetRx will
               have the right to contract with other PBMs. Any arrangement  with
               any other PBM will not adversely affect any financial arrangement
               between ESI and PlanetRx.  In addition,  ESI shall be given "most
               favored  nation"  financial terms compared to any other PBM, such
               that the total economic package to ESI under this Agreement shall
               be at least 20%  better  than that  offered or given to any other
               PBM with the same co-marketing type arrangement.

Change of Control
and Related  Items:

                    If a "Change of Control"  of either ESI or PlanetRx  occurs,
               then the  Agreement  may be terminated at the option of the party
               which was not the subject of the Change of  Control.  If PlanetRx
               is the subject of the Change of Control,  ESI must  exercise  its
               termination  right  prior to the  consummation  of the  Change of
               Control  transaction  and,  if it does so  exercise  such  right,
               PlanetRx shall pay ESI a substantial  termination payment. If ESI
               is the subject of the Change of Control,  PlanetRx  must exercise
               its termination  right prior to the consummation of the Change of
               Control  transaction.  Regardless  of which party  exercises  its
               termination right, the parties will have a transition period of 6
               months prior to the actual termination date; provided that during
               the transition  period the parties  co-marketing  and co-branding
               activities  shall cease. If the agreement is not  terminated,  it
               will  continue  in  effect  in  accordance  with its  terms.  For
               purposes of the  foregoing,  "Change of Control" shall be defined
               as the time at which a person,  or two or more persons  acting in
               concert, acquire more than 50% of the voting power of the entity.

Events of Default
and Default:

                    Following is a non-exhaustive  lists of events that shall be
               considered "Events of Default" under the Agreement:  (i) PlanetRx
               shall engage in  prescribing  medicine or referring  consumers to
               physicians for prescriptions; (ii) PlanetRx shall fail to pay any
               payment to ESI when due, or (iii) PlanetRx shall fail to maintain
               its  privacy  structure  in  accordance  with  state and  federal
               regulatory   requirements  and  industry  standards,  as  may  be
               reflected in  certification  standards of  organizations  such as
               Trustee, BBB, VIPPS, the NABP or similar organizations.  Upon the
               occurrence  of an Event of Default,  ESI shall have the option to
               (along with any other rights it may have under the agreement,  at
               law or in equity): (a) terminate the Agreement;  or (b) terminate
               only the  provisions of the  Agreement  which require ESI to name
               PlanetRx as the exclusive  internet  pharmacy in its networks and
               suspend any  co-branding or  co-marketing  efforts.  In addition,
               upon  the  first  payment  default,  ESI  shall  be  entitled  to
               perpetual  license rights in the PlanetRx software and technology
               such that ESI may use,  modify,  etc. the software and technology
               for its own purposes.  If the first default remains uncured and a
               subsequent  payment default occurs,  or if the initial default is
               cured  but two or more  defaults  occur  within  a  twelve  month
               period,  ESI shall have  additional  shares issued to it having a
               value  equal  to  two  times  the  amount  of all  the  defaulted
               payments, and also be entitled to additional Board representation
               such that it shall control a majority of the Board positions.

Pharmacy Chains:

                    ESI shall have the right, in cooperation  with PlanetRx,  to
               negotiate  any  strategic  alliance  or equity  participation  in
               PlanetRx by pharmacy  chains,  subject to review and  approval of
               PlanetRx's  Board,  in its sole  discretion.  PlanetRx  shall not
               grant such right to any other parties.  Regulatory Approvals: The
               transaction  is   conditioned   upon  receipt  of  any  necessary
               regulatory approvals.

Board and Other
Approvals:

                    Notwithstanding  anything to the contrary  contained herein,
               all terms and conditions of the transactions described herein are
               expressly  subject to the receipt of  approval by the  respective
               Boards  of  Directors  of  ESI  and   PlanetRx,   in  their  sole
               discretion,  and in the  case of  ESI,  to  satisfactory  tax and
               accounting  review  of  the  proposed  transactions  contemplated
               hereby, and, in the case of PlanetRx, approval of the Series A, B
               and C Preferred Shareholders, if necessary.

               entity ("NewCo") and PlanetRx merges into NewCo, with NewCo being
               renamed "PlanetRx" immediately after the transaction (NewCo being
               the entity  referred to herein as  "PlanetRx"),  or other similar
               structure such that the  transaction is tax deferred for ESI, and
               pursuant to which ESI receives  common stock in PlanetRx equal to
               19.9%  (post-transaction and post-initial public offering ("IPO")
               of the fully diluted equity interests.

                    The parties  agree to seek  confidential  treatment  for any
               portions of the Agreement  that are required to be filed with any
