           NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                (unaudited)



1.  In the opinion of management, the accompanying unaudited condensed
    consolidated financial statements include all adjustments, consisting
    of only normal recurring accruals, necessary to present fairly the
    financial position, results of operations and cash flows of the
    Company.  The Company's accounting policies are described in the Notes
    to Consolidated Financial Statements in the Company's 1993 Annual
    Report.  Interim results are not necessarily indicative of the
    operating results for the full year.

2.  During the first quarter of 1994, the Company entered into an
    agreement with a bank to sell certain foreign based accounts
    receivable up to $14 million, which approximated the proceeds for the
    current quarter.  The selling price is partially determined by foreign
    exchange rates at the end of each quarter.

3.  As of January 1, 1994, the Company adopted Statement of Financial
    Accounting Standards No. 115, Accounting for Certain Investments in
    Debt and Equity Securities.  Under this standard, the Company is
    required to classify its marketable securities (all of which are debt
    securities) into one or more of the following categories: held-to-
    maturity, trading or available-for-sale.  At March 31, 1994, all of
    the Company's marketable securities are classified as available-for
    sale.  Under this statement, these securities are recorded at fair
    market value and unrealized gains and losses are recorded as part of
    shareholders' equity.  Following is a summary of marketable securities
    as of March 31, 1994: 


                                                  Unrealized     Amortized
     (dollars in thousands)            Value    Gains    Losses    Cost

     U.S. Government securities      $196,614    $444    $2,366  $198,536
     (average maturity of 24 months)

     Corporate debt securities         87,862     212     1,415    89,065
     (average maturity of 24 months)

     Proceeds from maturities and other sales of securities, which were
     reinvested, during the quarter ended March 31, 1994 were $247.7
     million.  Gross realized gains and losses on these sales were
     immaterial.

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


Results of Operations

For the first quarter ended March 31, 1994, the Company reported net income
of $11.2 million or $0.31 per share as compared to net income of $11.3
million or $0.32 per share in the first quarter of 1993.  

Total revenues for the first quarter of 1994 were $44.8 million, as
compared to $35.4 million in the first quarter of 1993.  Revenues for the
current quarter were higher than the comparable 1993 quarter due mostly to
higher royalty income.  During the first quarter, the Company signed a
licensing agreement with Eli Lilly & Co. ("Lilly") covering certain patent
rights for gene expression methods.  Under this agreement, Lilly paid the
Company approximately $10M in royalties that related to sales occurring
before 1994.  Royalties from alpha interferon sales by Schering-Plough
Corporation declined in the current quarter as compared to 1993, due
primarily to lower sales in Japan.  Sales in Japan declined in anticipation
of a 17 percent decrease in the price of alpha interferon, which became
effective on April 1.  The Company, in general, expects continued increases
in sales of licensed products but at lower growth rates than had been
experienced during 1992 and 1993.  However, there are numerous health care
reform initiatives currently underway in the United States and other major
pharmaceutical markets and it is not yet clear what effect, if any, these
initiatives or other developments may have on product sales by the
Company's licensees.  In addition, these sales levels may fluctuate from
quarter to quarter due to the timing and extent of major events such as new
indication approvals or licensing arrangements.

Interest income for the current quarter increased from the comparable 1993
amount due primarily to the increase in invested funds generated from
higher revenue and profit levels.

Total expenses for the current quarter were $31.9 million as compared to
$23.1 million in the 1993 quarter.  Research and development expense
increased $8.4 million, due to the expanded clinical development of the
Company's lead drug candidates, Hirulog(TM) thrombin inhibitor and
recombinant beta interferon.  Both drug candidates are in Phase II and
Phase III clinical trials for a variety of indications.  The Company
expects its research and development costs to continue to increase as it
expands the clinical programs for Hirulog(TM), recombinant beta interferon
and other therapeutics.  General and administrative expenses increased by
$2.0 million due mostly to higher costs related to market development
efforts, legal and personnel related costs.  Other expenses decreased
primarily due to a charge in the prior year's quarter for the write-off of
the Company's remaining interest in a European joint venture.

Income tax expense for the current quarter was $1.7 million which is
substantially less than the amount computed at U.S. federal statutory rates
because of the utilization of net operating loss carryforwards.  



Financial Condition                                                  Page 8

At March 31, 1994, cash, cash equivalents and marketable securities
amounted to $296.1 million, a $25.7 million increase from the $270.4
million on hand at the end of 1993.  Working capital increased $4.6 million
to $282.3 million.  Net cash provided from operating activities for the
three months ended March 31, 1994 was $33.7 million while the Company's
common stock option and purchase plans provided $2.2 million.  Outflows of
cash included investments in property and equipment and patents of $7.1
million.  The decrease in accounts receivable is primarily attributed to an
agreement the Company entered into with a bank in the first quarter of 1994
to sell certain accounts receivable.

The Company is the general partner of Biogen Medical Products Limited
Partnership ("BMPLP").  BMPLP was formed for the continued development of
commercial products based on gamma interferon and interleukin-2 (the
"partnership products").  The Company agreed to extend the term of the
development contract with BMPLP until December 31, 1994.  The Company has
not incurred any significant costs with respect to BMPLP in 1994 but has
the option to provide up to $9.2 million to BMPLP to continue development
of the partnership products.  

During the fourth quarter of 1993, the Company commenced construction of a
150,000 square foot building in Cambridge, Massachusetts to house research
laboratories and offices.  The anticipated cost of construction, including
land, is approximately $40 million.  Upon completion of the building in
1995, the Company has the option, subject to certain conditions, to obtain
a secured term loan with a bank for up to $25 million for a period of up to
10 years. 

The Company believes that the financial resources available to it,
including its current working capital and its existing and anticipated
contractual relationships, may be sufficient to finance its planned
operations and capital expenditures for the near term.  However, the
Company expects that it may have additional funding needs, the extent of
which will depend upon the level of royalties and product sales, the
outcome of clinical trial programs, the receipt and timing of required
regulatory approvals for products, the results of research and development
efforts and business expansion opportunities.  Accordingly, from time to
time, the Company may obtain funding through various means which could
include collaborative agreements, lease financings, sales of equity or debt
securities and other financing arrangements.

With respect to the unaudited condensed consolidated financial information
of Biogen, Inc. and its subsidiaries at March 31, 1994 and for the three
month periods ended March 31, 1994 and 1993, Price Waterhouse reported that
they have applied limited procedures in accordance with professional
standards for a review of such information.  However, their separate report
dated April 15, 1994 appearing herein, states that they did not audit and
they do not express an opinion on that unaudited condensed consolidated
financial information.  Price Waterhouse has not carried out any
significant or additional audit tests beyond those which would have been
necessary if their report had not been included.  Accordingly, the degree
of reliance on their report on such information should be restricted in
light of the limited nature of the review procedures applied.  Price
Waterhouse is not subject to the liability provisions of Section 11 of the
Securities Act of 1933 for their report on the unaudited condensed
consolidated financial information because that report is not a "report" or
a "part" of the registration statement prepared or certified by Price
Waterhouse within the meaning of sections 7 and 11 of the Act.

                     REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of Biogen, Inc.

We have reviewed the accompanying condensed consolidated balance sheet of
Biogen, Inc. and its subsidiaries as of March 31, 1994, and the related
condensed consolidated statements of income and of cash flows for the three
month periods ended March 31, 1994 and 1993.  This financial information is
the responsibility of the Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical
procedures to financial data and making inquiries of persons responsible
for financial and accounting matters.  It is substantially less in scope
than an audit conducted in accordance with generally accepted auditing
standards, the objective of which is the expression of an opinion regarding
the financial statements taken as a whole.  Accordingly, we do not express
such an opinion.

Based on our review, we are not aware of any material modifications that
should be made to the accompanying condensed consolidated financial
information for it to be in conformity with generally accepted accounting
principles.

We previously audited in accordance with generally accepted auditing
standards, the consolidated balance sheet as of December 31, 1993, and the
related consolidated statements of income, of cash flows and of
shareholders' equity for the year then ended (not presented herein), and in
our report dated January 20, 1994 we expressed an unqualified opinion on
those consolidated financial statements.  In our opinion, the information
set forth in the accompanying condensed consolidated balance sheet as of
December 31, 1993, is fairly stated in all material respects in relation to
the consolidated balance sheet from which it has been derived.
