          FUNDS, A DELAWARE  BUSINESS TRUST, (THE "VANGUARD TRUST") ON BEHALF OF
          ITS SERIES,  VANGUARD MID-CAP GROWTH FUND (THE "VANGUARD  FUND"),  AND
          PIC  INVESTMENT  TRUST,  A DELAWARE  BUSINESS  TRUST  (THE  "PROVIDENT
          TRUST"), ON BEHALF OF ITS SERIES, PROVIDENT INVESTMENT COUNSEL MID CAP
          FUND A ("PROVIDENT FUND")

Ladies and Gentlemen:

     You  have   requested  our  opinion  as  to  certain   federal  income  tax
consequences of the  reorganization  of Provident Fund which will consist of (i)
the transfer of all or substantially  all of the assets of the Provident Fund to
the Vanguard Fund, in exchange  solely for shares of beneficial  interest of the
Vanguard Fund (the "Vanguard Fund Shares");  (ii) the assumption by the Vanguard
Fund of the liabilities of the Provident Fund; and (iii) the distribution of the
Vanguard  Fund  Shares to the  shareholders  of the  Provident  Fund in complete
liquidation  of the Provident  Fund as provided  herein,  all upon the terms and
conditions hereinafter set forth in the Agreement (the "Reorganization").

     In  rendering  our  opinion,  we have  reviewed  and  relied  upon  (a) the
Agreement  and Plan of  Reorganization,  dated as of the __ day of  ___________,
2002, by and between the Vanguard Trust and the Provident  Trust,  (b) the proxy
materials  provided to shareholders of the Provident Fund in connection with the
Special  Meeting of  Shareholders  of the Provident Fund held on  _____________,
2002, (c) certain  representations  concerning the Reorganization  made to us by
the Vanguard Trust and the Provident Trust in letters dated _____________,  2002
(the  "Representation  Letters"),  (d) all other documents,  financial and other
reports and corporate  minutes which we deemed relevant or appropriate,  and (e)

                                       1

such statutes,  regulations,  rulings and decisions as we deemed material to the
rendition of this opinion. All terms used herein,  unless otherwise defined, are
used as defined in the Agreement.

     For purposes of this  opinion,  we have assumed that each of the  Provident
Fund and the Vanguard Fund on the effective date of the Reorganization  satisfy,
and  following the  Reorganization,  the Vanguard Fund will continue to satisfy,
the  requirements  of  subchapter  M of the Internal  Revenue  Code of 1986,  as
amended (the "Code"), for qualification as a regulated investment company.

     Based on the  foregoing and provided the  Reorganization  is carried out in
accordance with the applicable laws of the State of Delaware,  the Agreement and
the Representation Letters, it is our opinion that:

     1. The Reorganization will constitute a tax-free  reorganization within the
meaning of Section  368(a)(1)(F)  of the Code,  and Provident  Fund and Vanguard
Fund will each be a party to a  reorganization  within  the  meaning  of Section
368(b) of the Code.

     2. No gain or loss will be recognized  by Provident  Fund upon the transfer
of all of its assets to  Vanguard  Fund in  exchange  solely for  Vanguard  Fund
Shares or upon the  distribution  of the Vanguard  Fund Shares to the  Provident
Fund's shareholders in exchange for their shares of the Provident Fund.

     3. No gain or loss will be  recognized by Vanguard Fund upon the receipt by
it of all of the assets of Provident  Fund in exchange  solely for Vanguard Fund
Shares  and  the  assumption  by the  Vanguard  Fund of the  liabilities  of the
Provident Fund.

     4. The tax basis of the assets of Provident  Fund received by Vanguard Fund
will be the same as the tax basis of such assets to Provident  Fund  immediately
prior to the Reorganization.

     5. The holding  period of the assets of Provident Fund received by Vanguard
Fund will be the same  holding  period  which  such  assets  had in the hands of
Provident Fund immediately prior to the Reorganization.

     6. No gain or loss will be recognized by the shareholders of Provident Fund
upon the  exchange  of their  Provident  Fund  Shares for  Vanguard  Fund Shares
(including  fractional  shares to which they may be entitled) and the assumption
by the Vanguard Fund of the liabilities of the Provident Fund.

     7. The  aggregate  tax basis of the  Vanguard  Fund Shares  received by the
shareholders of Provident Fund (including fractional shares to which they may be
entitled)  pursuant to the  Reorganization  will be the same as the basis of the
Provident Fund Shares held by the Provident  shareholder's  immediately prior to
the Reorganization.

     8.  The  holding  period  of  the  Vanguard  Fund  Shares  received  by the
shareholders of Provident Fund (including fractional shares to which they may be
entitled)  will  include  the  holding  period  of  the  Provident  Fund  Shares
surrendered in exchange  therefor,  provided that the Provident Fund Shares were
held as a capital asset on the effective date of the Reorganization.

                                       2

     9. For  purposes  of section  381 of the Code,  the  Vanguard  Fund will be
treated as the same  corporation as the Provident Fund and the tax attributes of
the Provident  Fund  enumerated in section  381(c) will be taken into account by
the   Vanguard   Fund  as  if  there   had  been  no   reorganization   (section
1.381(b)-1(a)(2)  of the  Regulations).  The taxable year of Provident Fund will
not end on the date of the  reorganization  and the part of the taxable  year of
taxpayer  before  the  reorganization  and the part of the  taxable  year of the
Vanguard Fund after the reorganization  will constitute a single taxable year of
the Vanguard Fund (section 381(b) of the Code, section  1.381(b)-1(a)(2)  of the
Regulations, and Rev. Rul. 57- 276, 1957-1 C.B. 126).

     This opinion letter  expresses our views only as to U.S. federal income tax
laws in effect as of the date hereof.  It represents  our best legal judgment as
to the matters  addressed  herein,  but is not binding on the  Internal  Revenue
Service or the courts.  Accordingly, no assurance can be given that the opinions
and analysis expressed herein, if contested,  would be sustained by a court. Our
opinion is based upon the Code, the applicable Treasury Regulations  promulgated
thereunder, the present position of the Internal Revenue Service as set forth in
published  revenue  rulings  and  revenue  procedures,   present  administrative
positions of the Internal Revenue Service, and existing judicial decisions,  all
of which are subject to change either prospectively or retroactively.  We do not
undertake to make any continuing analysis of the facts or relevant law following
the date of this letter.

     Our opinion is conditioned  upon the  performance by the Vanguard Trust and
the   Provident   Trust  of  their   undertakings   in  the  Agreement  and  the
Representation Letters.

     This opinion is being  rendered to Vanguard Fund and Provident Fund and may
be relied upon only by such funds and the shareholders of each fund.

                                        Very truly yours,

                                        MORGAN, LEWIS & BOCKIUS LLP

                                        3
