Item 2.
- -------
(a-c) This statement is being filed by Amerindo Investment Advisors Inc., a
California corporation whose principal executive offices are located at One
Embarcadero Center, Suite 2300, San Francisco, California, 94111 ("Amerindo"),
Amerindo Investment Advisors, Inc., a Panama corporation, whose principal
executive offices are located at Edificio Sucre, Calle 48 Este, Bella Vista,
Apartado 6277, Panama 5, Panama ("Amerindo Panama"), the Amerindo Investment
Advisors Inc. Profit Sharing Trust, whose address is 2655 Le Jeune Road, Coral
Gables, Florida 33134 (the "Plan"), the Amerindo Advisors (UK) Limited
Retirement Benefits Scheme, whose address is 43 Upper Grovesner Street, London
WIX 9PG England (the "Retirement Benefits Scheme"), and Alberto W. Vilar, Gary
A. Tanaka, James P.F. Stableford and Renata Le Port (sometimes hereinafter
collectively referred to as the "Reporting Persons"). Although this statement
is being made jointly by the Reporting Persons, each of them expressly
disaffirms membership in any group under Rule 13d-5 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise. Amerindo
and Amerindo Panama are sometimes hereinafter collectively referred to as the
"Advisor Entities."
Each of the Advisor Entities is an investment advisor, and all of the
subject securities have been purchased by the Advisor Entities (or, in the case
of securities held, by the Plan and the Retirement Benefits Scheme) in the
ordinary course of their respective businesses as investment advisors and not
with the purpose of effecting change or influencing the control of the issuer
or in connection with or as a participant in any transaction having such
purpose or effect, including any transaction subject to Rule 13d-3(b) under the
Exchange Act. Amerindo is registered as an investment advisor under the
Investment Advisors Act of 1940, as amended. Messrs. Vilar and Tanaka are the
sole shareholders and directors of each of the Advisor Entities. Mr. Vilar is
sole trustee of the Plan, and Messrs. Alberto W. Vilar, Gary A. Tanaka, James
P.F. Stableford and Ms. Renata Le Port are joint trustees of the Retirement
Benefits Scheme. The Plan and the Retirement Benefits Scheme are qualified
employee benefit plans. Because each of the Advisor Entities is obligated to
act in the best interests of its respective clients and in accordance with the
respective mandates of those clients, and because the trustee of the Plan and
the trustees of the Retirement Benefits Scheme are required to act in the best
interest of the beneficiaries thereof, there is no agreement between or among
any of the Reporting Persons to act together with respect to the issuer or its
securities, except that they may, from time to time and provided that
transactions are otherwise being effected at the same time, aggregate orders
for client accounts in order to receive more favorable trading terms.
(d-e) This statement is being filed as to the Common Stock of
Centocor Inc., Cusip Number 152342101.

Item 4. Ownership.
- ------ ---------
(a-c) The following table sets forth for each of the Advisor Entities and
for the Plan the aggregate number of shares of the Common Stock of the Issuer
beneficially owned by such person as of December 31, 1996, and the percentage
which such shares constitute of the total number of shares outstanding, as
reflected on the Issuer's Form 10Q for the Quarter ended September 30, 1996
(with beneficial ownership determined as set forth in Rule 13d-3 under the
Exchange Act, but with beneficial ownership being expressly disclaimed). Messrs.
Vilar and Tanaka, as the sole shareholders and directors of the Advisor
Entities, share with each other investment and dispositive power as to all
of the shares shown as owned by the Advisor Entities, who otherwise have sole
investment and dispositive power with respect thereto, except that each client
of the Advisor Entities has the unilateral right to terminate the advisory
agreement with the Advisor Entity in question on notice which typically need
not exceed 30 days. Mr. Vilar is sole trustee of the Plan, and Messrs.
Alberto W. Vilar, Gary A. Tanaka, James P.F. Stableford and Ms. Renata Le Port
are joint trustees of the Retirement Benefits Scheme.
