           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 1994 Annual
    Report.  Interim results are not necessarily indicative of the
    operating results for the full year.

2.  During the third quarter of 1994, the Company incurred a pre-tax
    charge to other expenses of $25 million as a result of its decision to
    discontinue its major activities associated with Hirulog(TM)
    development.  The charge consists of cash payments to a third-party
    manufacturer for product manufactured for clinical trials and to cover
    a portion of other costs incurred by the manufacturer in anticipation
    of ongoing Hirulog(TM) related activities, and cash payments for
    clinical research organizations, clinical investigators and
    institutions involved in clinical trials to cover noncancellable costs
    incurred by them in conducting clinical trials and in connection with
    wind-down activities.  Discontinuance of the Hirulog(TM) program did
    not result in any termination of employees or internal restructuring
    costs.  As of March 31, 1995, $6.1 million remained in reserve and is
    expected to be settled by the end of 1995.

3.  In March 1995, the Company completed construction of its research
    laboratory and office building in Cambridge, Massachusetts and
    exercised its option to obtain a 7.5% secured term loan with a bank
    for $25 million.  The annual principal payable in each of the years
    1996 through 1999 is $1.7 million with the balance due May 8, 2005.

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

Results of Operations

For the first quarter ended March 31, 1995, the Company reported net income
of $2.8 million or $0.08 per share as compared to net income of $11.2
million or $0.31 per share in the first quarter of 1994.  

Total revenues for the first quarter of 1995 were $36.0 million, as
compared to $44.8 million in the first quarter of 1994.  Revenues from
royalties and product sales for the current quarter were lower than the
comparable 1994 quarter, primarily because of the inclusion in the 1994
quarter of a one-time payment of approximately $10 million from Eli Lilly &
Co. ("Lilly") under a licensing agreement covering certain patent rights
for gene expression methods.  Under this agreement, Lilly paid the Company
in the first quarter of 1994 approximately $10 million in royalties that
related to sales occurring before 1994.  Ongoing royalties received from
licensee sales of hepatitis B vaccines, sold by SmithKline Beecham plc
("SmithKline") and Merck & Co., Inc. ("Merck"), increased and more than
offset the decrease in royalties received from Schering-Plough Corporation
("Schering-Plough"), the Company's licensee for alpha interferon.  Sales of
hepatitis B vaccines outside the United States increased 83% from the prior
year quarter.  The market for hepatitis B vaccines increased significantly
in Europe, primarily in France, where a vaccination program for infants and
adolescents was instituted during 1994.  Alpha interferon sales by
Schering-Plough declined in the current quarter, due primarily to lower
sales in Japan, which was driven by a 17% government-mandated decrease in
the price of alpha interferon, effective on April 1, 1994, and restrictions
on off-label usage.  In the near term, the Company expects overall sales of
licensee products to continue at current levels although royalty income may
fluctuate depending on changes in sales volumes for specific products. 
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,
vaccination programs or licensing arrangements.

Interest income for the current quarter increased from the comparable 1994
amount primarily due to higher interest rates.

Total expenses for the current quarter were $32.9 million as compared to
$31.9 million in the 1994 quarter.  Research and development expense
decreased $2.9 million, due to the Company's decision in the third quarter
of 1994 to discontinue its major activities associated with Hirulog(TM)
development.  Current quarter costs included increased regulatory and
development costs for AVONEX(TM) recombinant interferon beta while the 1994
quarter had higher costs, primarily for Hirulog(TM) clinical development. 
On May 4, 1995, the Company announced that it has filed with the European
Medicines Evaluation Agency for European market approval of AVONEX(TM) for
treatment of multiple sclerosis.  The Company also said it will file within
the next several weeks for U.S. Food and Drug Administration approval to
market the drug in the United States.  General and administrative expenses
increased by $1.6 million due mostly to higher costs related to market
development efforts, continued development of the Company's European
headquarters in Paris and legal and personnel related costs.  Other

                                                                     Page 8

 expenses included the effect of foreign exchange movements associated with
the sale of certain accounts receivable, losses from the sale of certain
marketable securities and interest on debt obligations.

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

Financial Condition                                                        

At March 31, 1995, cash, cash equivalents and marketable securities
amounted to $286.6 million, an $18.8 million increase from the $267.8
million on hand at the end of 1994.  Working capital increased $22.5
million to $269.3 million.  Net cash provided from operating activities for
the three months ended March 31, 1995 was $0.8 million while the Company's
common stock option and purchase plans provided $0.7 million.  The Company
also received $25.0 million under a secured term loan agreement with a
bank.  Outflows of cash included investments in property and equipment and
patents of $10.7 million.

In March 1995, the Company completed construction of its research
laboratory and office building in Cambridge, Massachusetts and exercised
its option to obtain a 7.5% secured term loan with a bank for $25 million. 
The annual principal payable in each of the years 1996 through 1999 is $1.7
million with the balance due May 8, 2005. 

In the first quarter of 1993, SmithKline initiated arbitration in the
United States regarding the rate of royalties payable from sales of
hepatitis B vaccines by SmithKline in the United States.  The amount paid
by SmithKline and in dispute as of December 31, 1994, was approximately $18
million.  In April 1995, an arbitration panel ruled in Biogen's favor.  An
appeal by SmithKline of this decision is possible.  However, the Company
believes that, in the event of such appeal, an adverse ruling is not
probable and, therefore no amount has been accrued. 

During 1995, the Company expects to begin construction on a biologics
manufacturing facility in Research Triangle Park, North Carolina.  The
estimated cost of construction, including land, is $57 million.

The Company currently believes that the financial resources available to
it, including its current working capital and its existing and anticipated
contractual relationships, will be sufficient to finance its planned
operations and capital expenditures for the near term.  However, the
Company 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 or mortgage 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, 1995 and for the three
month periods ended March 31, 1995 and 1994, Price Waterhouse LLP reported
that they have applied limited procedures in accordance with professional
standards for a review of such information.  However, their separate report
dated April 27, 1995 appearing herein, states that they did not audit and
they do not express an opinion on that unaudited condensed consolidated
financial information.  Price Waterhouse LLP 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 LLP 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 LLP 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, 1995, and the related
condensed consolidated statements of income and of cash flows for the three
month periods ended March 31, 1995 and 1994.  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, 1994, 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 February 7, 1995 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, 1994, is fairly stated in all material respects in relation to
the consolidated balance sheet from which it has been derived.
