Re:  Tax Opinion Regarding Redemption of Provident Investment
     Counsel Mid Cap Fund A Interest in PIC Mid Cap Portfolio

Ladies and Gentlemen:

You have  requested  our  opinion  with  respect to certain  federal  income tax
matters in connection with the complete redemption (the "REDEMPTION") by PIC Mid
Cap Portfolio  ("PROVIDENT  PORTFOLIO"),  a New York business trust taxable as a
partnership  for  federal  income tax  purposes,  of the  ownership  interest of
Provident  Investment Counsel Mid Cap Fund A ("PROVIDENT FUND"), a series of PIC
Investment  Trust  ("PIC  TRUST"),  a  Delaware  business  trust,  in  Provident
Portfolio.  This  opinion is  rendered  in  connection  with the  Redemption  as
described in the Agreement and Plan of Reorganization  dated as of February ___,
2002 (the  "REORGANIZATION  AGREEMENT"),  by and between PIC Trust, on behalf of
Provident Fund and by Vanguard  Whitehall Funds ("VANGUARD  TRUST"),  a Delaware
business trust, on behalf of Vanguard Mid Cap Growth Fund ("VANGUARD  FUND"),  a
series of Vanguard Trust, and adopts the applicable defined terms therein.

In this connection, we have examined, with respect to Provident Fund, (i) a copy
of the  Trust  Agreement  of PIC Mid Cap  Portfolio  dated  as of  December  29,
1997 (the "TRUST AGREEMENT"),  (ii) a copy of the Reorganization Agreement,
and (iii) representations of Provident Portfolio dated as of February ___, 2002,
furnished to us for purposes of this opinion.

We understand,  and the opinion  expressed below is based upon the  assumptions,
that:

(1) Provident Portfolio is an entity taxable as a partnership for federal income
tax  purposes  within the  meaning  of  Sections  7701 and 7704 of the  Internal
Revenue Code of 1986, as amended (the "CODE");

(2) Provident  Portfolio is an  "investment  partnership"  within the meaning of
Code  Section  731(c)(1)(C)(i).  The term  "investment  partnership"  means  any
partnership that has never been engaged in a trade or business and substantially
all of the assets (by value) of which have always  consisted of (I) money,  (II)
stock in a corporation,  (III) notes, bonds,  debentures,  or other evidences of
indebtedness,  (IV)  interest  rate,  currency,  or  equity  notional  principal
contracts,  (V) foreign  currencies,  (VI) interests in or derivative  financial
instruments (including options,  forward or futures contracts,  short positions,
and similar financial instruments) in any asset described in any other subclause
of this clause or in any commodity  traded on or subject to the rules of a board
of trade or  commodity  exchange,  (VII) other assets  specified in  regulations
prescribed  by the  Secretary,  or  (VIII)  any  combination  of  the  foregoing
(collectively,  "PERMITTED INVESTMENTS").  The activities of Provident Portfolio
have been limited to investing and trading in Permitted Investments;

(3)  Following  the  Redemption,  Provident  Portfolio  will  have at least  two
continuing partners;

(4) Provident Fund is an "eligible  partner"  within the meaning of Code Section
731(c)(3)(C)(iii),  which  provides that the term  "eligible  partner" means any
partner who,  before the date of the  distribution,  did not  contribute  to the
partnership any property other than cash or Permitted Investments;

(5) No  investor in  Provident  Portfolio  acquired  its  interest in  Provident
Portfolio in exchange for any asset other than cash;

(6) The assets to be  distributed  to Provident  Fund consist solely of cash and
marketable  securities  within the  meaning  of Code  Section  731(c)(2),  which
provides that the term "marketable  securities" means financial  instruments and
foreign currencies that are, as of the date of the distribution, actively traded
on an established securities market;

(7) [The assets held by Provident  Portfolio are neither unrealized  receivables
nor inventory of Provident Portfolio within the meaning of Code Section 751];

(8) The assets to be  distributed  to Provident Fund consist solely of Provident
Fund's  PRO  RATA,  in  proportion  to its  Interest  (as  defined  in the Trust
Agreement) in Provident Portfolio, share of each of the assets held by Provident
Portfolio; and

(9) The  adjusted  tax basis of  Provident  Fund in its  interest  in  Provident
Portfolio  equals or exceeds the amount of cash to be  distributed  to Provident
Fund pursuant to the Redemption.

Based upon the foregoing examination, assumptions and representations and upon a
review of such statutes,  regulations,  cases and other authorities as we deemed
necessary, we are of the opinion that:

(1) The Redemption will not be taxable to Provident  Portfolio or any partner in
Provident Portfolio  (including  Provident Fund) for federal income tax purposes
under Code Section 704(c)(1)(B), Code Section 731 or Code Section 737;

(2) The basis of the property  distributed  to Provident Fund shall be an amount
equal to the adjusted basis of Provident Fund's interest in Provident  Portfolio
reduced  by any money  distributed  in the  Redemption,  and such  basis will be
allocated according Code Section 732(b) and Code Section 732(c); and

(3) In determining the holding period of the property received by Provident Fund
in the  Redemption,  there shall be included  the  holding  period of  Provident
Portfolio, as determined under Code Section 1223, with respect to such property.

This  opinion is provided  solely to Provident  Fund,  Provident  Portfolio  and
Vanguard  Fund.  It  should  not be used or relied  upon by any other  person or
entity, other than Provident Fund, Provident Portfolio and Vanguard Fund, and is

the application of federal income tax law existing as of the date of this letter
to the  parties  named  above,  and we can give no  assurance  that  legislative

that would require modifications or revocations of our opinion expressed herein.
We assume no  responsibility or obligation to withdraw or to revise this opinion
or to notify any party if, at any time hereafter, there is a change in the Code,
Treasury Regulations, revenue rulings, revenue procedures, judicial decisions or
in the facts and  assumptions  set forth herein,  that in any manner affect this
opinion.
