Statement  on  Form  N-14  (File  No.   333-77042)  (the  "N-14   Registration

(1)  Facing Sheet of this Registration Statement.

(2)  Part C of this Registration Statement (including signature pages).

     Parts A and B are incorporated herein by reference from the Registrant's
Proxy Statement and Prospectus filed on February 19, 2002 under Rule 497 under
the Securities Act of 1933, as amended (the "Securities Act").

     This Post-Effective Amendment No. 1 is being filed to file as Exhibit No.
12 to this Registration Statement the Tax Opinion of Sidley Austin Brown & Wood
LLP, tax counsel for the Registrant, and to file as Exhibit 16 to this
Registration Statement a power of attorney executed by each of the current
members of the Registrant's Board of Directors. The tax opinion relates to the

Trust, Merrill Lynch Mid Cap Growth Fund, Inc., Master Mid Cap Growth Trust,
Merrill Lynch Large Cap Growth Fund, a series of the Registrant, and Master
Large Cap Series Trust.

                                     PART C

                                OTHER INFORMATION

Item 15. Indemnification.

     Reference is made to Article VI of the Registrant's Articles of
Incorporation, Article VI of Registrant's By-Laws, Section 2-418 of the
Maryland General Corporation Law and Section 9 of the Distribution Agreement.

     Insofar as the conditional advancing of indemnification moneys for
actions based on the Investment Company Act of 1940, as amended (the
"Investment Company Act"), may be concerned, Article VI of the Registrant's
By-Laws provides that such payments will be made only on the following
conditions: (i) advances may be made only on receipt of a written affirmation
of such person's good faith belief that the standard of conduct necessary for
indemnification has been met and a written undertaking to repay any such
advance if it is ultimately determined that the standard of conduct has not
been met; and (ii) (a) such promise must be secured by a security for the
undertaking in form and amount acceptable to the Registrant, (b) the
Registrant is insured against losses arising by receipt by the advance, or (c)
a majority of a quorum of the Registrant's disinterested non-party Directors,
or an independent legal counsel in a written opinion, shall determine, based
upon a review of readily available facts, that at the time the advance is
proposed to be made, there is reason to believe that the person seeking
indemnification will ultimately be found to be entitled to indemnification.

     In Section 9 of the Distribution Agreement relating to the securities
being offered hereby, the Registrant agrees to indemnify the FAM Distributors,
Inc. (the "Distributor") and each person, if any, who controls the Distributor
within the meaning of the Securities Act, against certain types of civil
liabilities arising in connection with the Registration Statement or
Prospectus and Statement of Additional Information.

     Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to Directors, officers and controlling persons of the
Registrant and the principal underwriter pursuant to the foregoing provisions
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a Director,
officer, or controlling person of the Registrant and the principal underwriter
in connection with the successful defense of any action, suit or proceeding)
is asserted by such Director, officer or controlling person or the principal
underwriter in connection with the shares being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
