REPORT OF INDEPENDENT ACCOUNTANTS
May 28, 1998
To the Participants and Administrator
of the Biogen Savings Plan
We have audited the accompanying statement of assets available for benefits of
the Biogen Savings Plan (the "Plan") as of December 31, 1997 and 1996 and the
related statement of changes in assets available for benefits for the year ended
December 31, 1997. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
In our report dated July 30, 1997, we were unable to, and did not, express an
opinion on the 1996 financial statements because, at the instruction of the plan
administrator, we did not perform any auditing procedures with respect to the
information summarized in Note 4 in those financial statements. In conjunction
with our audit of the 1997 financial statements, the plan administrator
instructed us to perform, and we did perform, an audit of the 1996 financial
statements in accordance with generally accepted auditing standards.
Accordingly, we are now able to express an opinion on the 1996 financial
statements.
In our opinion, the financial statements referred to in the first paragraph of
this report present fairly, in all material respects, the assets available for
benefits of the Plan as of December 31, 1997 and 1996, and the changes in assets
available for benefits for the year ended December 31, 1997 in conformity with
generally accepted accounting principles.

May 28, 1998
Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The additional information included in
Schedules I and II is presented for purposes of additional analysis and is not a
required part of the basic financial statements but is additional information
required by ERISA. The Fund Information in the statement of changes in assets
available for benefits is presented for purposes of additional analysis rather
than to present the changes in assets available for benefits of each fund.
Schedules I and II and the Fund Information have been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, are fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

BIOGEN SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
1. DESCRIPTION OF THE PLAN
The following brief description of the Biogen Savings Plan (the "Plan") is
provided for general information purposes only. Participants should refer
to the Plan agreement for more complete information.
GENERAL INFORMATION
Biogen, Inc. (the "Company") established the Plan as a deferred
profit-sharing plan under Section 401(a) of the Internal Revenue Code of
1986, effective January 1, 1987. The Plan is designed to allow eligible
employees to accumulate savings for retirement in the Plan without paying
income taxes until the savings are actually received.
ADMINISTRATION OF THE PLAN
The Plan is administered by the Savings Plan Committee (the "Plan
Committee"), whose members are appointed by the Company. Fidelity
Management Trust Company is the Plan trustee (the "Trustee").
Administrative costs of the Plan have been assumed by the Company.
PARTICIPATION
Participation in the Plan is voluntary. Each employee of the Company is
eligible to participate in the Plan upon the attainment of age 21 unless
he/she is (a) a student employed on a temporary basis, (b) an employee of a
non-U.S. subsidiary or division of the Company, or (c) a member of a
collective bargaining unit.
CONTRIBUTIONS
Eligible employees may make savings deposits to the Plan in whole
percentages of their gross salary ranging from a minimum of 2% to a maximum
of 18%, subject to certain limitations. For each pay period, the Company
will make a matching contribution of units of the Biogen Inc., stock fund
equal in value to 25% of each employee's savings deposit up to a maximum of
6% of the employee's gross salary, subject to certain limitations.
INVESTMENT OF CONTRIBUTIONS
Company matching contributions are invested in the Biogen, Inc. stock fund.
Prior to December 5, 1997, the matching contribution was invested directly
in Biogen, Inc. stock. On December 5, 1997 the amounts in the stock account
were converted into units of the Biogen, Inc. stock fund which includes
Biogen, Inc. stock and cash or short term investments. Employee
contributions are invested at the direction of the employee in increments
of 10% in any combination of the following investment options:
o An intermediate bond fund designed to earn a high level of current
return. It is invested in Fidelity's Intermediate Bond Fund.
o A balanced fund designed to preserve principal balance by investing in
a diversified portfolio of high yielding stocks and bonds. It is
invested in Fidelity's Puritan Fund.
o An aggressive growth fund invested which seeks to achieve capital
appreciation. It is invested in Fidelity's Magellan Fund.
o A US government money market fund seeks high current earnings while
preserving capital and liquidity. It is invested in Fidelity's
Retirement Government Money Market Fund.

BIOGEN, INC.
BIOGEN SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
o A growth company fund which seeks to provide capital appreciation from
investments primarily in common stock of companies with above-average
growth characteristics. It is invested in Fidelity's Growth Company
Fund.
o An international equity fund which seeks capital growth, current
income and growth of income. It is invested in the Fidelity
International Growth & Income Fund.
o An asset allocation fund that seeks total return with reduced risk
over the long term. It is invested in the Fidelity Asset Manager Fund.
o A long term growth fund which seeks to provide investment results that
correspond to the total return performance of common stock of
companies publicly traded in the US. It is invested in the Fidelity US
Equity Index Fund.
o A corporate bond fund that seeks to replicate the price and interest
performance of the debt securities in the Lehman Brothers Aggregate
Bond Index. It is invested in the Fidelity US Bond Index Fund.
o A fund which seeks to provide capital appreciation from investments in
companies which are undervalued or which possess valuable fixed
assets. It is invested in the Fidelity Value Fund.
The Plan added the following investment options effective October 1, 1997:
o A fund which seeks to provide capital appreciation from investments in
companies which are undervalued or which are out of favor with other
investors and that could offer the possibility for significant growth.
It is invested in the Fidelity Low-Priced Stock Fund.
o A fund that seeks capital growth over the long term from investments
in common stocks of foreign and domestic companies. It is invested in
the Janus Worldwide Fund.
o A fund that seeks long term capital growth and current income from
investments in stocks of companies organized and operating principally
outside the United States. It is invested in the USAA International
Fund.
The Plan added the following investment option effective January 1, 1998.
o A fund that pools money to buy shares of Biogen, Inc. stock and cash
or short-term investments. It is invested in the Biogen, Inc. stock
fund. Note: Prior to January 1, 1998 only the employer match was
invested in Biogen, Inc. stock.
Dividends, interest, and other distributions received in any fund are
reinvested in the same fund.
VESTING
Participants are fully vested in their savings deposit accounts and
rollover accounts at all times. Participants will vest in the employer's
matching contribution at a rate of 25% for each year of Plan service and
will be fully vested after four years of Plan service. Participants become
100% vested in employer's matching contributions upon retirement or
termination of employment due to disability.

BIOGEN, INC.
BIOGEN SAVINGS PLAN
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
WITHDRAWALS AND DISTRIBUTIONS
Distributions are generally payable at termination of employment due to
retirement, disability, death or any other reason. Distribution payments
are made in cash in a lump sum for employees' contributions and in whole
shares of stock for Company matching contributions. Forfeitures of
nonvested amounts are used to reduce the amount of future Company matching
contributions.
LOANS
Participants may borrow against their savings deposits. Loans will bear a
reasonable interest rate determined by the Company. Repayment of loans is
made by direct withholdings of a participant's salary for a period not to
exceed five years (ten years for a residential loan). The minimum loan
amount is $1,000 and a participant may borrow up to a maximum of 50% of the
participant's vested account balance or $50,000, whichever is smaller.
There is no minimum service requirement for a participant to be eligible
for a loan.
PLAN AMENDMENT AND TERMINATION
The Company has the right to amend, suspend or terminate the Plan, but may
not do so in a way which would divest a participant of accrued vested
benefits. If the Plan is terminated, the Trustee will distribute the assets
held in the trust, after payment of expenses, in such a manner as the
Committee shall determine. The Company currently has no intention to
terminate the Plan.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts and disclosures in the
financial statements. Actual results could differ from those estimates. The
following is a summary of significant accounting policies which are in
conformity with generally accepted accounting principles consistently
followed by the Plan in the preparation of its financial statements.
BASIS OF ACCOUNTING
The financial statements of the Plan are prepared on the accrual basis of
accounting.
INVESTMENTS
Plan investments are stated at fair value. The Company stock is valued at
its quoted market price. Mutual fund investments are valued at net asset
value representing the value of which shares of the fund may be purchased
or redeemed. Loans to participants are stated at principal plus accrued
interest, which approximates fair value.
Purchases and sales of securities are recorded on a trade-date basis. Cost
is determined on the average cost basis. Net appreciation or depreciation,
which includes realized and unrealized gains or losses on investments, is
reflected for the year in the statement of changes in assets available for
plan benefits.

INCOME TAXES
No provision for income taxes has been made in the financial statements as
the Plan qualifies as a tax-exempt entity under Section 401 of the Internal
Revenue Code ("Code"). The Plan has received a favorable determination
letter dated June 5, 1996 from the Internal Revenue Service. The Plan has
since been amended and a new letter has not been requested. Management has
asserted the Plan, as amended, and its operations have been and continue to
be in accordance with all applicable provisions of the Code and the
Employee Retirement Income Security Act of 1974 ("ERISA").
3. LOANS TO PARTICIPANTS
At December 31, 1997 and 1996, the Plan had loans receivable from
participants aggregating $707,329 and $474,929, respectively. Interest
rates on the loans range from 7.0% to 11.0% annually. The loans are secured
by the participant's interest in the Plan.
