ITEM 1. Security and Issuer.
- ------- -------------------
The class of equity securities to which this statement relates is the
Common Stock of Parametric Technology Corp. ("the Issuer"), whose principal
executive offices are located at 128 Technology Drive, Waltham, MA 02154.
ITEM 2. Identity and Background.
- ------ -----------------------
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, the address of which is Gables
International Plaza, 2655 Le Jeune Road, Suite 1112, Coral Gables, FL 33134
(the "Plan"), and Alberto W. Vilar and Gary A. Tanaka. Although this statement
is being made jointly by Amerindo, Amerindo Panama, the Plan and Messrs. Vilar
and Tanaka, 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 is registered as an investment advisor under the Investment
Advisors Act of 1940, as amended. Messrs. Alberto W. Vilar and Gary A. Tanaka,
whose business addresses are the same as those set forth for Amerindo and each
of whom is a U.S. citizen, are the only directors and executive officers of
Amerindo Panama. They are also the only directors and executive officers of
Amerindo, other than Mr. James H. Furey, Chief Operating Officer, and
Mr. Joaquin Garcia-Larrieu, Chief Financial Officer. Mr. Furey's business
address is at Amerindo's offices at 399 Park Avenue, New York, New York 10022,
and Mr. Garcia's business address is Gables International Plaza, 2655
Le Jeune Road, Suite 1112, Coral Gables, FL 33134. Amerindo, Amerindo Panama,
the Plan and Messrs. Vilar and Tanaka are sometimes hereinafter collectively
referred to as the "Reporting Persons." Messrs. Vilar, Tanaka, Furey and
Garcia are sometimes hereinafter collectively referred to as the "Other Named
Individuals."
During the last five Quarters, none of the Reporting Persons or Other
Named Individuals has been convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors), nor has any such individual or entity
been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction as a result of which proceeding such individual or
entity was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to,
Federal or state securities laws or finding any violation with respect to
such laws.
ITEM 3. Source and Amounts of Funds or Other Consideration.
- ------- --------------------------------------------------
All purchases of the subject securities by the Reporting Persons
have been in the ordinary course of the respective businesses of Amerindo
and Amerindo Panama (collectively, the "Advisor Entities") as investment
advisors. Accordingly, the funds used to purchase the subject securities
have been client funds pertaining to accounts under management, except that
the shares owned by the Plan were purchased with Plan assets. Purchases of
the Issuer's securities by the Named Individuals would all be and have all
been made with their personal funds, except that margin credit may also be,
and may have been, employed.
- 8 of 14 -
<PAGE>
ITEM 4. Purpose of Transaction.
- ------- ----------------------
All of the subject securities have been purchased by the Advisor
Entities in the ordinary course of their respective businesses as
investment advisors (or, in the case of securities held by the Plan, in the
ordinary course of investing for the Plan), 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. Additionally, 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, 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. Any of the subject securities acquired or
which might in the future be acquired by any of the Named Individuals have
been and would be acquired for investment 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.
ITEM 5. Interests in Securities of Issuer.
- ------- ---------------------------------
(a) See Exhibit "A" attached hereto for information setting forth for
each of the Reporting Persons and for each Named Individual the aggregate number
of shares of the Common Stock of Issuer beneficially owned by such person as of
January 10, 1997, and the percentage which such shares constitute of the total

Exhibit).
(b) Messrs. Vilar and Tanaka share voting and dispositive power
over all shares shown as owned by any of the Reporting Persons, except that Mr.
Vilar has sole voting and dispositive power over the 4,000 shares held by the
Plan; however, each client of the Advisor Entities has the unilateral right to
terminate the advisory arrangement with the Entity in question on notice which
typically need not exceed 30 days. Each of the Other Named Individuals has
sole voting and dispositive power as to the shares shown in Exhibit "A" as
owned by him.
(c) The table contained in Exhibit "B" attached hereto sets forth for
each of the Reporting Persons and Named Individuals information concerning all
acquisitions and dispositions of Issuer's Common Stock by any such person
