              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

General

The  accompanying  interim  financial  statements  have been  prepared  by Medco
Research,  Inc. (the "Company") in accordance with generally accepted accounting
principles.  Certain disclosures and information  normally included in financial
statements  have been condensed or omitted.  In the opinion of the management of
the  Company,  these  financial  statements  contain all  adjustments  (all of a
recurring  nature)  necessary for a fair  presentation  for the interim periods.
These statements should be read in conjunction with the financial statements and
notes  included in the  Company's  Annual Report on Form 10-K for the year ended
December 31, 1994.

The Company  considers  all highly liquid  investments  with a maturity of three
months or less when purchased to be cash equivalents.

Class Action Litigation

In September  1993, the Company,  and certain of its past and then directors and
officers  along  with  Kemper  Securities  Group,  Inc.  and  Vector  Securities
International, Inc., were named in two class action lawsuits filed in the United
States District Court, Northern District of Illinois.  The suits allege that the
Company  and the other  defendants  violated  Section  10 (b) of the  Securities
Exchange  Act of 1934  and  Rule  10 (b) (5)  promulgated  thereunder  and  made
negligent  misrepresentations  in  connection  with the  Company's  January 1992
secondary  stock  offering  and  otherwise  during the period  November 19, 1990
through April 28, 1993. In September  1994, the Company's  motion to dismiss was
granted.  Plaintiffs appealed in October 1994. On May 16, 1995 the United States
Court of Appeals for the 7th Circuit reversed the dismissal.

On November 7, 1995, the Company served its answers to the complaints in the two
consolidated class action lawsuits.  The answers denied the material allegations
of the complaints and asserted affirmative defenses, including among others that
the Company did not commit  securities  fraud, that the Company did not make any
untrue  representations,  that the Company made  adequate  disclosure  about the
Adenoscan(R)  NDA and that the complaints were not filed timely by reason of the
applicable statute of limitations.

During the fiscal quarter ending March 31, 1996, the Company  expects to serve a
summary judgment motion seeking the dismissal of these lawsuits on the merits.

It is not possible at this time to evaluate the outcome;  however, the Company's
management  believes the class action lawsuits are totally without merit and has
instructed its counsel to take all appropriate  action to vigorously  defend the
Company.

Fujisawa/Abbott Settlement

In May 1995, the litigation  pending between  Fujisawa USA, Inc.  (Fujisawa) and
the Company,  regarding the rights to manufacture and market Adenoscan(R) in the
United States and Canada,  was settled and the Company and Abbott  Laboratories,
Inc. (Abbott) terminated their manufacturing and marketing  agreements regarding
the Adenoscan(R) drug and settled Medco's  outstanding  obligations  thereunder.
Pursuant to the settlement agreement with Fujisawa,  the December 21, 1988 Joint
Development and License  Agreement between the parties remains in full force and
effect except as expressly amended and Fujisawa remains the Company's  exclusive
licensee to manufacture and market Adenoscan(R) in the United States and Canada.
Fujisawa  agreed to pay the  Company  within  fifteen  days after FDA  marketing
clearance of Adenoscan(R) the sum of $2 million,  representing  certain research
and  development  expenses  incurred  by the  Company,  and to pay  the  Company
royalties  of 29 percent  of  Adenoscan(R)  net sales in the  United  States and
Canada for the first five years after the  commencement  of commercial  sales in
each territory.  Thereafter  Fujisawa would pay the Company  royalties of 25% of
sales  until June 10, 2007 at which time  Fujisawa  would have a paid up license
within such territories.

Fujisawa  also agreed to pay  royalties  to the Company in respect of periods of
more than thirty days in which it is unable to fulfill  Adenoscan(R)  orders for
reasons other than force majeure and other specified  events,  such royalties to
be at the then  prevailing rate based on the average daily sales of Adenoscan(R)
during the preceding  twelve months.  Fujisawa also agreed generally to maintain
an  inventory  of at least  six  months of  Adenoscan(R)  finished  product  and
work-in-process,  to be stored at  multiple  locations,  to provide  the Company
within one year with data necessary to qualify Fujisawa's Melrose Park, Illinois
plant as an alternate  Adenoscan(R)  manufacturing  facility and to use its best
efforts to identify  and provide  data to the Company to qualify with the FDA an
alternate  supplier of the adenosine raw material  necessary for the manufacture
of Adenoscan(R). The parties also agreed as soon as practicable to enter into an
agreement to jointly  develop  adenosine  based products  having  indications as
cardioprotective  agents,  such as MEDR640,  and for that purpose Fujisawa would
grant to the Company an exclusive  sublicense  under U.S. patent 4,880,783 under
which  Fujisawa  is  the  exclusive  licensee.  Fujisawa  would  have  exclusive
manufacturing  and  marketing  rights  in the  U.S.,  Canada,  Mexico  and other
territories  to be  agreed  upon and it would pay the  Company  25% of net sales
within  the  territories.  The  companies  would  share  equally  all  costs  of
development and any royalties due to third parties.

The  Company  agreed to pay  Abbott a  royalty  of two  percent  of net sales of
Adenoscan(R)  for the first five years of commercial  sales,  up to a maximum of
$5.35  million,  of which $2 million was payable  within  fifteen days after FDA
marketing  clearance  of  Adenoscan(R)  as an advance  royalty  payment  and the
remainder  payable  based upon actual  sales of  Adenoscan(R).  The Company also
agreed that if at the conclusion of the five year period Abbott had not received
an aggregate of $5.35 million, including the $2 million advance, Medco would pay
Abbott any deficiency.  Abbott  relinquished  all claims to royalty  payments in
excess of that amount.  Finally,  the Company agreed to pay Abbott  $330,560 for
the  reimbursement  of research and development  and other expenses  incurred in
connection with Adenoscan(R). The Company expensed $330,560 in the first quarter
of 1995.

Included in liabilities at September 30, 1995 is an accrued  liability  (current
and  non-current  portion)  of $3.27  million  relating  to the  balance  of the
Company's  guaranteed  royalty  obligation  to  Abbott.  Included  in  assets at
September  30, 1995 is a deferred  asset  (current and  non-current  portion) of
$3.18 million  relating to royalties to be received by the Company from Fujisawa
and paid by the  Company to Abbott.  Four  percent  of the  royalties  of 29% of
Adenoscan(R)  net sales  received by the Company will be applied to the deferred
asset and 25% will be  recognized  as royalty  revenue.  At such  time,  if any,
during  the first five years that the  deferred  asset is fully  recovered,  the
Company  thereafter will recognize royalty revenue of 29% through the end of the
five year period.  The Company will write-off any portion of this deferred asset
at such time,  if any,  in which it becomes  probable  that the  incremental  4%

deferred asset.


           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


The following is  management's  discussion  and analysis of certain  significant
factors  which have  affected  the  Company's  operating  results and  financial
position during the periods included in the accompanying financial statements.


RESULTS OF OPERATIONS

Third Quarter and Nine Months of 1995 Compared To Third Quarter and Nine Months
of 1994

Operating  Results.  The third  quarter  resulted  in a loss of $0.5  million or
$(0.04) per share,  and a nine month loss of $2.8  million or $(0.26) per share,
compared  to losses of $0.6  million or $(0.06) per share,  and $2.5  million or
$(0.22) per share, for the year earlier periods.

Revenue.  The Company's royalty revenue for the third quarter 1995 increased 14%
and  26% for the  first  nine  months  over  the  comparable  periods  of  1994,
reflecting increased sales of adenosine (Adenocard(R) and Adenoscan(R)) from the
July 31st launch of  Adenoscan(R)  in the U.S. by Fujisawa  USA,  the  Company's
North American  licensee.  Fujisawa is responsible for  substantially all of the
royalty revenue to the Company.

Total royalty  revenue  decreased 16% for the third quarter 1995 compared to the
second quarter 1995. The decrease in total royalty revenue reflects the expected
reduction  in  Adenocard(R)  sales  which  occurred  with  the  introduction  of
Adenoscan(R).  However,  net  royalty  revenue  (royalty  revenue  less  royalty
expense)  increased  by 21% since there is no royalty  expense  associated  with
Adenoscan(R) (see discussion of royalty expense below).

Fujisawa's launch of Adenoscan(R) is still in progress.  Short-term goals are to
sell  Adenoscan(R) to purchasers of  Adenocard(R)  and to open accounts with and
supply wholesalers,  distributors and radiopharmacies.  Intermediate  objectives
include placing  Adenoscan(R)  on the formularies of managed care  organizations
and  on  the  lists  of   insurance-reimbursable   products,   implementing   an
Adenoscan(R) advertisement campaign in medical journals,  disseminating recently
available pharmacoeconomic data demonstrating cost savings obtained from the use
of  Adenoscan(R)  compared to  dipyridamole,  the market leader,  and converting
users of dipyridamole.

Fujisawa has made substantial  progress in achieving its immediate  objective of
establishing a distribution  infrastructure  for  Adenoscan(R),  and it also has
begun to realize some of the above-referenced intermediate objectives.  However,
Fujisawa's  Adenoscan(R)  sales  through  September 30, 1995 appear to represent
principally the initial inventory buildup necessary to fulfill potential product
orders (and not sales to end-users). Accordingly, reported Adenoscan(R) sales do
not  indicate  the level of  actual  Adenoscan(R)  use.  The  Company  therefore
believes  that no  inferences  can be drawn at this  time  about  Adenoscan(R)'s
market  penetration or sales trends,  or the level at which  Adenocard(R)  sales
will stabilize.

Costs  and  Expenses.  Total  costs and  expenses  for the  third  quarter  1995
increased  4% and 20% for the first nine months over the  comparable  periods of
1994.

Royalty  expense,  which  represents  one-half of royalty  revenue earned by the
Company from  Adenocard(R)  sales and is payable to the  University  of Virginia
Alumni Patents  Foundation from which the Company  acquired  exclusive rights to
Adenocard(R), decreased 37% during the third quarter and increased 9% during the
nine months,  reflecting  the  expected  reduction  in  Adenocard(R)  sales that
occurred with the  introduction  of  Adenoscan(R).  There is no royalty  expense
associated with the royalty income received from Adenoscan(R) sales.

Research  and  Development  expenditures  for the third  quarter  1995 were $2.0
million and $5.6  million  for the first nine  months of 1995,  compared to $1.3
million and $4.1 million for the comparable  periods of 1994, an increase of 51%
and 36%,  respectively.  This increase  largely  reflects the  additional  costs
associated with a pivotal  bioequivalence  study and  manufacturing  scale-up of
BiDil(R).  On October 18, 1995, the Company  announced that its data analyses of
two pivotal Phase III clinical  trials indicate that its novel imaging agent for
the  assessment  of  myocardial   viability,   ViaScint(TM)   (I-123  Iodophenyl
pentadecanoic  acid),  appears  to  provide  the  means to  predict,  with  high
accuracy,  which patients will have  improvement in cardiac  function  following
revascularizaton. Based on the foregoing, the Company plans to pursue the filing
of New Drug Applications with the U.S. Food and Drug Administration   (FDA)  for
BiDil(R) and ViaScint(TM)  targeted for no later than first quarter of 1996. The
Company accordingly expects to incur in its fourth  quarter  1995  research  and
development  expenses  at  a level which could be significantly higher, and will
not be less than that  incurred in the third quarter in order to complete  these
FDA filings.

General and administrative expenses for the third quarter 1995 were $0.8 million
and $0.9 million for the comparable  period of 1994, a decrease of 17%.  General
and administrative expenses for the first nine months were $3.3 million and $3.0
million for the  comparable  period of 1994,  an increase of 10%. The nine month
increase  is  attributed  to the  accounting  treatment,  resulting  in one-time
charges,  associated  with three separate events from the second quarter (1) the
settlement  of the  litigation  among Medco  Research,  Fujisawa USA, and Abbott
Laboratories  related to the manufacturing and marketing rights to Adenoscan(R),
(2)  resignation  of the former  President of the Company,  and (3) the expenses
incurred   preceding  the   termination  of  a  proposed  merger  with  Repligen
Corporation.

FINANCIAL CONDITION

As of  September  30,  1995,  the  Company  had total  cash and  investments  of
$37,995,000 comprised of $5,486,000 of cash and cash equivalents and $32,509,000
of investments,  primarily in U.S. Treasury Notes and debt securities of various
federal governmental agencies. The Company's working capital as of September 30,
1995 was $30,474,000 an increase of $5,591,000 as compared to December 31, 1994,
due to a shift from  non-current  investments  to current  investments  in first
quarter 1995.

Included in liabilities at September 30, 1995 is an accrued  liability  (current
and  non-current  portion)  of $3.27  million  relating  to the  balance  of the
Company's  guaranteed  royalty  obligation to Abbott.  Included in the assets at
September  30, 1995 is a deferred  asset  (current and  non-current  portion) of
$3.18 million  relating to royalties to be received by the Company from Fujisawa
and paid by the  Company to Abbott.  Four  percent  of the  royalties  of 29% of
Adenoscan(R)  net sales  received by the Company will be applied to the deferred
asset and 25% will be  recognized  as royalty  revenue.  At such  time,  if any,
during  the first five years that the  deferred  asset is fully  recovered,  the
Company  thereafter will recognize royalty revenue of 29% through the end of the
five year period.  The Company will write-off any portion of this deferred asset
at such time,  if any,  in which it becomes  probable  that the  incremental  4%
royalty revenue will be  insufficient  to recover the remaining  balance of this
deferred asset.

IMPACT OF INFLATION

Although  it is  difficult  to  predict  the  impact of  inflation  on costs and
revenues of the Company in connection with the Company's products,  two of which
are currently  being  commercially  produced and marketed,  the Company does not
anticipate that inflation will  materially  impact its costs of operation or the
profitability of its products when marketed.
