                       IMPORTANT SHAREHOLDER INFORMATION
 
   

                            CONESTOGA FAMILY OF FUNDS
 
     The document you hold in your hands contains your Combined Proxy
Statement/Prospectus and proxy card. A proxy card is, in essence, a ballot. When
you vote your proxy, it tells us how to vote on your behalf on important issues
relating to Conestoga. If you simply sign the proxy without specifying a vote,
your shares will be voted in accordance with the recommendations of the Board of
Trustees.
 
     We urge you to spend a few minutes with the Combined Proxy
Statement/Prospectus, fill out your proxy card, and return it to us. Voting your
proxy, and doing so promptly, enables Conestoga to avoid conducting additional
mailings. When Shareholders do not return their proxies in sufficient numbers,
the Funds may bear the expense of follow-up solicitations.
 
     Please take a few moments to exercise your right to vote. Thank you.
 
     The Combined Proxy Statement/Prospectus constitutes the Proxy Statement of
Conestoga Family of Funds for the meeting of its shareholders. It also
constitutes the Prospectus of CoreFunds, Inc. for eight of its portfolios which
are to issue shares in connection with the proposed reorganization -- the Cash
Reserve, Tax-Free Reserve, Treasury Reserve, Value Equity Fund, Intermediate
Bond Fund, Pennsylvania Municipal Bond Fund, Balanced Fund and International
Growth Fund. This document does not constitute a Prospectus for three newly
organized portfolios of CoreFunds, Inc. that are to issue shares in the
reorganization because they will be deemed to continue the operations of the
acquired Conestoga portfolios; they are the Special Equity Fund, Bond Fund and
Short-Term Income Fund.

                         THE CONESTOGA FAMILY OF FUNDS
                            680 EAST SWEDESFORD ROAD
                         WAYNE, PENNSYLVANIA 19087-1658
 
   
February 15, 1996
    
 
Dear Conestoga Funds Shareholder:
 
   
     The Board of Trustees of The Conestoga Family of Funds is pleased to call a
Special Meeting of Shareholders, to be held at 10:00 a.m., on March 22, 1996, at
The Wilmington Hilton, 630 Naamans Road, Wilmington, Delaware.
    
 
   
     As you may know, CoreStates Financial Corp ('CoreStates') and Meridian
Bancorp, Inc. ('Meridian') recently announced a plan to merge, in a transaction
expected to close during the second quarter of 1996. Meridian Bancorp, Inc., is
the parent company of the investment adviser to the Conestoga Funds. In
anticipation of the consummation of that merger, management of both companies
deemed it wise to consider the consolidation of the mutual fund investment
advisory activities of Meridian and CoreStates into one entity. Similarly, it
was deemed appropriate to consider the merger of the Conestoga Funds into
CoreFunds, Inc. ('CoreFunds'), an open-end management investment company, in
order to create one consolidated family of mutual funds and offer Shareholders
more investment options in an efficient manner. The Conestoga Funds Board of
Trustees believes that these actions are in the best interests of the Conestoga
Funds' Shareholders.
    
 
   
     The Conestoga Board of Trustees has carefully reviewed the proposal to
combine all portfolios of The Conestoga Family of Funds with the CoreFunds'
portfolios with similar investment objectives and policies (the 'Transaction'),
and has considered the effects of this Transaction on Shareholder value with
respect to investment performance, expenses levels, and Shareholder services.
The Board of Trustees has also considered the interim advisory and sub-advisory
agreements for the Funds that are described in the attached materials if the
merger of CoreStates Financial Corp and Meridian Bancorp, Inc. occurs before the
Funds' consolidations, as is expected. In light of their consideration, the
Board of Trustees unanimously recommends the approval of the Transaction. As you
evaluate the proposal, please note the following points:
    
 
   
     o The dollar value of your investment in the Conestoga Funds before the
       Transaction will NOT change, and will be the same immediately after the
       transaction although the Funds you have invested in, as well as the
       number of shares and the net asset value of each share, may be different.
    
 
     o The Transaction will be tax-free and will not involve any sales loads,
       commissions or transaction charges.
 
   
     o The investment objective and policies of your new portfolio will be
       substantially similar to your portfolio's current objective and policies,
       except as noted in the enclosed Combined Proxy Statement/Prospectus.
    
 
     o The CoreFunds service providers have agreed to waive fees and reimburse
       expenses for a period of one year after the reorganization, if necessary,
       to ensure that the operating expenses of the CoreFunds portfolios are
       limited to the ratios stated in the Combined Proxy Statement/Prospectus.
 
   
     THE BOARD OF TRUSTEES RECOMMENDS THE APPROVAL OF THIS TRANSACTION IN LIGHT
OF THE FOLLOWING SHAREHOLDER BENEFITS:
    
 
   
     o The Transaction will result in a broader array of investment
       opportunities available to Shareholders.
    
 
     o Existing purchase and redemption features will remain in place.
 
     o There is the potential for economies of scale in portfolio management
       resulting from the larger asset size.

     A proxy card is enclosed for your use in the Shareholder Meeting. This card
represents shares you held as of the record date, January 26, 1996. IT IS
IMPORTANT THAT YOU COMPLETE, SIGN, AND RETURN YOUR PROXY CARD IN THE ENVELOPE
PROVIDED AS SOON AS POSSIBLE. This will ensure that your shares will be
represented at the Shareholders Meeting to be held on March 22, 1996.
    
 
                                          Sincerely,

     This Combined Proxy Statement/Prospectus is furnished in connection with
the solicitation of proxies by the Board of Trustees of the Conestoga Family of
Funds ('Conestoga') in connection with a Special Meeting (the 'Meeting') of
Shareholders ('Shareholders') to be held on March 22, 1996 at 10:00 a.m.
(Eastern time) at The Wilmington Hilton, 630 Naamans Road, Wilmington, Delaware,
at which Shareholders will be asked to consider and approve a proposed Agreement
and Plan of Reorganization dated February 8, 1996 (the 'Reorganization
Agreement'), by and between Conestoga and CoreFunds, Inc. ('CoreFunds') and the
matters contemplated therein. A copy of the Reorganization Agreement is attached
as Appendix I.
    
 
   
     Conestoga and CoreFunds are both open-end, management investment companies.
Meridian Investment Company ('MIC') currently provides investment advisory
services to Conestoga. CoreStates Investment Advisers, Inc. ('CoreStates
Advisers') provides investment advisory services to CoreFunds. In reviewing the
proposed reorganization (the 'Reorganization'), the Conestoga Board considered
the pending merger of Meridian Bancorp, Inc., the parent company of MIC, and
CoreStates Financial Corp, the parent company of CoreStates Advisers (the
'Holding Company Merger'); the effect of such merger on Conestoga; the
recommendations of MIC and CoreStates Advisers with respect to the proposed
consolidation of Conestoga and CoreFunds; the fact that the Reorganization would
constitute a tax-free reorganization; and the fact that the interests of
Shareholders would not be diluted as a result of the Reorganization.
    
 
   
     The Reorganization Agreement provides that initially each of the following
eight investment portfolios of Conestoga (collectively, the 'Reorganizing
Portfolios') will transfer substantially all its assets and known liabilities to
the existing CoreFunds investment portfolio (collectively, the 'Existing
CoreFunds Portfolios') identified below opposite its name:
    
 

REORGANIZING PORTFOLIOS                           EXISTING COREFUNDS PORTFOLIOS
- -----------------------------------               -----------------------------

Cash Management Fund                              Cash Reserve

Tax-Free Fund                                     Tax-Free Reserve
 
U.S. Treasury Securities Fund                     Treasury Reserve
 
Equity Fund                                       Value Equity Fund
 
Intermediate Income Fund                          Intermediate Bond Fund
 
Pennsylvania Tax-Free                             Pennsylvania Municipal
  Bond Fund                                         Bond Fund
                                   
Balanced Fund                                     Balanced Fund
 
International Equity Fund                         International Growth Fund

 
   
     The Reorganization Agreement also provides that subsequently each of the
following three investment portfolios of Conestoga (collectively, the
'Continuing Portfolios') will transfer all its assets and known liabilities to
the newly-organized CoreFunds investment portfolio (collectively, the 'New
CoreFunds Portfolios') identified below opposite its name:
    
 

CONTINUING PORTFOLIOS                             NEW COREFUNDS PORTFOLIOS
- -----------------------------------               -----------------------------
Special Equity Fund                               Special Equity Fund
 
Bond Fund                                         Bond Fund
 
Short-Term Income Fund                            Short-Term Income Fund

 
<PAGE>
   
     In exchange for the transfers of these assets and liabilities, CoreFunds
will issue shares in the eleven CoreFunds investment portfolios listed above
(collectively, the 'CoreFunds Portfolios') to the corresponding Conestoga
investment portfolios listed above (collectively, the 'Conestoga Portfolios').
The initial transaction between the Reorganizing Portfolios and the Existing
CoreFunds Portfolios is referred to herein as the 'Reorganizing Portfolios
Transaction' and the subsequent transaction between the Continuing Portfolios
and the New CoreFunds Portfolios is referred to herein as the 'Continuing
Portfolios Transaction.' The transactions are expected to occur on or after
April 8, 1996 and April 15, 1996, respectively.
    
 
   
     The Conestoga Portfolios have two classes of shares outstanding, as do the
CoreFunds Portfolios. Holders of each class of shares of a Conestoga Portfolio
will receive the class of shares of the corresponding CoreFunds Portfolio as set
forth in the table on pages 29 and 30 under 'Information Relating to the
Proposed Reorganization -- Description of the Reorganization Agreement.'
    
 
   
     The Conestoga Portfolios will make liquidating distributions of the
CoreFunds Portfolios' shares to the Shareholders of the Conestoga Portfolios, so
that a holder of a class of shares in a Conestoga Portfolio will receive a class
of Shares (as described herein) of the corresponding CoreFunds Portfolio with
the same aggregate net asset value as the Shareholder had in the Conestoga
Portfolio immediately before the transaction. Following the Reorganization,
Shareholders of the Conestoga Portfolios will be Shareholders of their
corresponding CoreFunds Portfolios, and Conestoga will be terminated under state
law and the Investment Company Act of 1940, as amended.
    
 
     The Existing CoreFunds Portfolios currently are conducting investment
operations as described in this Combined Proxy Statement/Prospectus. The New
CoreFunds Portfolios have recently been organized for the purpose of continuing
the investment operations of the Conestoga Special Equity Fund, Bond Fund and
Short-Term Income Fund.
 
   
     The Reorganization Agreement provides that Conestoga will enter into an
interim investment advisory agreement with MIC (or its successor), and that MIC
will enter into an interim sub-advisory agreement with Marvin and Palmer
Associates, Inc. for the Conestoga International Equity Fund. The interim
advisory agreement, and the sub-advisory agreement for the International Equity
Fund, will be in effect for the Reorganizing Portfolios between the Holding
Company Merger and the consummation of the Reorganizing Portfolios Transaction.
The interim advisory agreement will be in effect for the Continuing Portfolios
between the Holding Company Merger and the consummation of the Continuing
Portfolios Transaction. The interim advisory and sub-advisory agreements will
contain substantially the same terms as Conestoga's current investment advisory
and sub-advisory agreements.
    
 
   
     This Combined Proxy Statement/Prospectus sets forth the information that a
Shareholder of Conestoga should know before voting on the Reorganization
Agreement (and related transactions), and should be retained for future
reference. The Prospectuses relating to the shares of the Existing CoreFunds
Portfolios, which describe the operations of those Funds, accompany this
Combined Proxy Statement/Prospectus. Additional information is set forth in the
Statements of Additional Information relating to those Funds and this Combined
Proxy Statement/Prospectus, which are dated November 1, 1995 and February 6,
1996, respectively, and in the Prospectuses and Statement of Additional
Information, dated February 21, 1995 (as revised November 3, 1995) and May 1,
1995 (as revised November 3, 1995), respectively, relating to Conestoga. Each of
these documents is on file with the Securities and Exchange Commission (the
'SEC'), and is available without charge upon oral or written request by writing
or calling either Conestoga or CoreFunds at the respective addresses or
telephone numbers indicated above. The information contained in the Prospectuses
and Statement of Additional Information, dated February 21, 1995 (as revised
November 3, 1995) and May 1, 1995 (as revised November 3, 1995), respectively,
relating to Conestoga is incorporated herein by reference.
    
 
   
     This Combined Proxy Statement/Prospectus constitutes the Proxy Statement of
Conestoga for the meeting of its Shareholders, and CoreFunds' Prospectus for the
shares of its Existing CoreFunds Portfolios that have been registered with the
SEC and are to be issued in connection with the Reorganization. Because the New
CoreFunds Portfolios will be deemed to be continuations of the Continuing
Portfolios, this Combined Proxy Statement/Prospectus does not constitute a
prospectus for the shares that will be issued in the Continuing Portfolios
Transaction.
    
 
   
     This Combined Proxy Statement/Prospectus is expected to first be sent to
Shareholders on or about February 15, 1996.

                                    SUMMARY
 
     The following is a summary of certain information relating to the proposed
Reorganization, the parties thereto and the related transactions, and is
qualified by reference to the more complete information contained elsewhere in
this Combined Proxy Statement/Prospectus, the prospectuses and statements of
additional information of Conestoga and CoreFunds, and the Reorganization
Agreement attached to this Combined Proxy Statement/Prospectus as Appendix I.
Conestoga's Annual Report to Shareholders may be obtained free of charge by
calling 1-800-344-2716 or writing 680 East Swedesford Road, Wayne, Pennsylvania
19087-1658. CoreFunds Annual Report to Shareholders may be obtained free of
charge by calling 1-800-355-CORE or writing 680 East Swedesford Road, Wayne,
Pennsylvania 19087-1658.
 
     PROPOSED REORGANIZATION.  Based upon their evaluation of the relevant
information presented to them, and in light of their fiduciary duties under
federal and state law, Conestoga's and CoreFunds' Boards, including their
members who are not 'interested persons' within the meaning of the Investment
Company Act of 1940 (the '1940 Act'), have determined that the proposed
Reorganization is in the best interests of Conestoga's and CoreFunds'
Shareholders, respectively, and that the interests of existing Shareholders of
Conestoga and CoreFunds, respectively, will not be diluted as a result of such
Reorganization.
 
   
     The Holding Company Merger is expected to precede the Reorganization.
Because this merger will result in a change in control of MIC, the existing
investment advisory and sub-advisory agreements for Conestoga will, by their
terms, automatically terminate upon the Holding Company Merger. The
Reorganization Agreement provides that Conestoga will enter into an interim
investment advisory agreement with MIC (or its successor) and that MIC will
enter into an interim sub-advisory agreement with Marvin and Palmer Associates,
Inc. ('Marvin and Palmer') for the Conestoga International Equity Fund. The
interim advisory agreement, and the sub-advisory agreement for the International
Equity Fund, will be in effect for the Reorganizing Portfolios between the
Holding Company Merger and the consummation of the Reorganizing Portfolios
Transaction. The interim advisory agreement will be in effect for the Continuing
Portfolios between the Holding Company Merger and the consummation of the
Continuing Portfolios Transaction. The provisions of the interim advisory and
sub-advisory agreements, including the fee rates, will be the same as those of
the existing advisory and sub-advisory agreements. See 'Interim Investment
Advisory and Sub-Advisory Agreements' below.
    
 
   
     The Cover Page and pages 1-28 hereof summarize the proposed Reorganization,
including the interim investment advisory and sub-advisory agreements.
    
 
   
     REASONS FOR THE REORGANIZATION.  The primary reason for the Reorganization
is the pending merger between Meridian Bancorp, Inc., the parent of MIC, and
CoreStates Financial Corp. If this merger is completed, the currently existing
investment advisory contract between the Conestoga Portfolios and MIC, would be
terminated. MIC and CoreStates Advisers have recommended that each of the
Conestoga Portfolios be reorganized as described in this Combined Proxy
Statement/Prospectus shortly after the proposed merger of the bank holding
companies. In light of this recommendation, after consideration of the reasons
therefor and the proposed operations of the combined funds after the
Reorganization, and in consideration of the fact that the Reorganization will be
tax-free and will not dilute the interests of Conestoga Shareholders, the Board
of Trustees of Conestoga has authorized the Agreement and Plan of Reorganization
and recommended approval of the Reorganization by Shareholders.
    
 
     FEDERAL INCOME TAX CONSEQUENCES.  Shareholders of the Conestoga Portfolios
will recognize no gain or loss for federal income tax purposes on their receipt
of shares of the CoreFunds Portfolios. Shareholders of the CoreFunds Portfolios
will have no tax consequence from the Reorganization. The Conestoga Portfolios
will incur no federal tax purposes on their issuance of shares in the
Reorganization. See 'Information Relating to the Proposed Reorganization --
Federal Income Tax Consequences.'

<PAGE>
     OVERVIEW OF THE CONESTOGA PORTFOLIOS AND COREFUNDS PORTFOLIOS.  There are
no material differences between the investment objectives and policies of the
Continuing Portfolios and the corresponding New CoreFunds Portfolios. The
investment objectives and policies of the Reorganizing Portfolios are similar to
those of the corresponding Existing CoreFunds Portfolios.
 
CONESTOGA CASH MANAGEMENT FUND AND COREFUNDS CASH RESERVE.
 
     The Conestoga Cash Management Fund's investment objective is to seek
current income with liquidity and stability of principal. CoreFunds Cash
Reserve's investment objective is to provide as high a level of current income
as is consistent with liquidity and relative stability of principal. Each
pursues its investment objective by investing in a diversified portfolio of high
quality money market instruments.
 
CONESTOGA TAX-FREE FUND AND COREFUNDS TAX-FREE RESERVE.
 
     The Conestoga Tax-Free Fund's investment objective is to seek current
income which is exempt from regular federal income tax with liquidity and
stability of principal. CoreFunds Tax-Free Reserve's investment objective is to
provide as high a level of current interest income that is exempt from federal
income taxes as is consistent with liquidity and relative stability of
principal. Both Funds intend, under normal market conditions, to invest at least
80% of their assets in short-term, high quality municipal obligations, the
interest on which is exempt from regular federal income tax. CoreFunds Tax-Free
Reserve intends to invest, when possible, its assets in municipal securities
exempt from Pennsylvania income taxation.
 
CONESTOGA U.S. TREASURY SECURITIES FUND AND COREFUNDS TREASURY RESERVE.
 
     The Conestoga U.S. Treasury Securities Fund's investment objective is to
seek current income with liquidity and stability of principal. CoreFunds
Treasury Reserve's investment objective is to provide current interest income,
liquidity and safety of principal. Each pursues its investment objective by
investing in short-term obligations of the U.S. Treasury and in repurchase
agreements relating to such Treasury obligations.
 
CONESTOGA EQUITY FUND AND COREFUNDS VALUE EQUITY FUND.
 
   
     The investment objective of the Conestoga Equity Fund is to seek capital
growth by investing principally in a diversified portfolio of common stocks of
companies with large, medium or small capitalizations. The investment objective
of CoreFunds Value Equity Fund is to provide maximum total return, including
capital appreciation and investment income, in excess of stock market indices
such as the S&P 500 Index, as measured over a period of time. CoreFunds Value
Equity Fund expects to change its name and investment policies before the
Reorganizing Portfolios Transaction to more closely resemble the investment
policies of the Conestoga Equity Fund.
    
 
CONESTOGA INTERMEDIATE INCOME FUND AND COREFUNDS INTERMEDIATE BOND FUND.
 
   
     The Conestoga Intermediate Income Fund's primary investment objective is to
seek current income by investing principally in a diversified portfolio of debt
securities with expected or remaining maturities of ten years or less, and its
secondary objective is to seek capital growth. The CoreFunds Intermediate Bond
Fund's investment objective is to provide a moderate level of current income
consistent with conservation of capital, by investing substantially all of its
assets in a diversified portfolio of intermediate-term, fixed income obligations
which will have an expected average weighted maturity of one to five years.
CoreFunds Intermediate Bond Fund expects to change its name before the
Reorganizing Portfolios Transaction to 'CoreFunds Short Intermediate Bond Fund'
to more accurately reflect the manner in which the Fund is being managed.
    
 
CONESTOGA PENNSYLVANIA TAX-FREE BOND FUND AND COREFUNDS PENNSYLVANIA MUNICIPAL
BOND FUND.
 
     The Conestoga Pennsylvania Tax-Free Bond Fund's investment objective is to
seek a high level of current income consistent with the preservation of capital,
which income is exempt from federal individual income tax and, to the extent
possible, from Pennsylvania state and local personal income
 
                                       2
<PAGE>
tax, and is not a tax preference item under the federal alternative minimum tax.
CoreFunds Pennsylvania Municipal Bond Fund seeks current income exempt from
federal and Pennsylvania income taxation with preservation of capital by
investing primarily in a non-diversified portfolio of municipal securities.
 
CONESTOGA BALANCED FUND AND COREFUNDS BALANCED FUND.
 
     The Conestoga Balanced Fund's investment objective is to seek a balance of
capital appreciation and current income consistent with the preservation of
capital. CoreFunds Balanced Fund's investment objective is to provide total
return while preserving capital. Both Funds pursue their objective by investing
in a combination of equity and fixed income securities.
 
CONESTOGA INTERNATIONAL EQUITY FUND AND COREFUNDS INTERNATIONAL GROWTH FUND.
 
     The Conestoga International Equity Fund's investment objective is to seek
long-term growth of capital. CoreFunds International Growth Fund's investment
objective is long-term capital appreciation, consistent with reasonable risk.
Both Funds invest at least 65% of their total assets in diversified portfolios
of equity securities of issuers located outside of the United States.
 
   
     See 'Comparison of Investment Policies and Risk Factors' below and the
Conestoga and CoreFunds Prospectuses, which are incorporated by reference
herein, for a description of the similarities and differences between the
investment objectives and policies of the Reorganizing Portfolios and the
corresponding Existing CoreFunds Portfolios.

     Pursuant to the Conestoga investment advisory contract, MIC provides
investment research and management to Conestoga and conducts a continuous
investment program. MIC also directs the
 
                                       3
<PAGE>
investments of the Conestoga Portfolios in accordance with each Portfolio's
investment objectives, policies and limitations, and creates and maintains all
necessary books and records.
 
   
     Marvin and Palmer provides sub-advisory services to the International
Equity Fund under a sub-advisory agreement between MIC and Marvin and Palmer.
The sub-adviser assists MIC in providing a continuous investment program for the
International Equity Fund, including investment research and management with
respect to all securities and investments and cash equivalents of the portfolio.
The sub-adviser provides the services under this agreement in accordance with
the International Equity Fund's investment objective, policies, and limitations.
For the services provided as the International Equity Fund's sub-adviser, Marvin
and Palmer is entitled to receive a fee from MIC, computed daily and paid
monthly, at the annual rate of .75% of the first $100 million of the Fund's
average daily net assets, .70% of the next $100 million of the Fund's average
daily net assets, .65% of the third $100 million of the Fund's average daily net
assets, and .60% of the Fund's average daily net assets in excess of $300
million.
    
 
   
     Since May 1, 1995, administrative services have been provided to Conestoga
by SEI Financial Management Corporation ('SFM') a wholly-owned subsidiary of SEI
Corporation ('SEI'). For its services, SFM receives a fee, calculated daily and
paid monthly, at the annual rate of .17% of the average aggregate daily net
assets of each Conestoga Portfolio. For the period May 1, 1995, through the end
of Conestoga's fiscal year (i.e., October 31, 1995), SFM received administration
fees (after fee waivers) at the effective annual rates of 0.17%, 0.17%, 0.15%,
0.12%, 0.12%, 0.16%, 0.17%, 0.17%, 0.17%, 0.17% and 0.17% of the average daily
net assets of the Cash Management, Tax-Free, U.S. Treasury Securities, Equity,
Special Equity, Bond, Intermediate Income, Pennsylvania Tax-Free Bond,
Short-Term Income, Balanced and International Equity Funds, respectively. Prior
to May 1, 1995, administrative services were provided to Conestoga by The
Winsbury Company ('Winsbury'). For its services, Winsbury received a fee,
calculated daily and paid monthly, at the annual rate of .20% of the average
daily net assets of each Conestoga Portfolio. For the fiscal period November 1,
1994 through April 30, 1995, Winsbury received administration fees, net of
voluntary fee reductions, at the effective annual rates of 0.20%, 0.09%, 0.20%,
0.20%, 0.09%, 0.16%, 0.15% and 0.10% of the average daily net assets of the Cash
Management, Tax-Free, U.S. Treasury Securities, Equity, Special Equity, Bond,
Intermediate Income and Pennsylvania Tax-Free Bond Funds, respectively. The
Short-Term Income, Balanced and International Equity Funds had not commenced
investment operations prior to May 1, 1995.
    
 
     SFM also serves as Conestoga's transfer agent and State Street Bank and
Trust Company serves as sub-transfer agent for Conestoga pursuant to an
agreement with the administrator. For these services, SFM receives an annual fee
equal to .02% of each Conestoga Portfolio's total assets, an annual per
shareholder account charge of $25 per account, plus out-of-pocket expenses.
 
     Citibank, N.A. provides custodial services to each Conestoga Portfolio
except the International Equity Fund. The Bank of New York provides custodial
services to the International Equity Fund. It is anticipated that on or about
March 7, 1996, CoreStates Bank, N.A. will begin providing custodial services to
each Conestoga Portfolio except the International Equity Portfolio.
 
     SEI Financial Services Company ('SFS') is the principal distributor for
Conestoga. Under the distribution agreement, SFS acts as the agent of Conestoga
in connection with the offering of shares of each Conestoga Portfolio.
 
   
     Conestoga has adopted a Distribution and Services Plan pursuant to Rule
12b-1 under the 1940 Act (the 'Conestoga 12b-1 Plan'). Under the Conestoga 12b-1
Plan, the class of shares known as the Retail Shares of each of the Conestoga
Portfolios bears the expense of distribution fees payable to SFS at an annual
rate of up to .40% of the average daily net asset value of such Portfolio's
outstanding Retail Shares to finance activities which are principally intended
to result in the sale of Retail Shares. SFS may enter into agreements with
financial institutions and industry professionals which provide distribution
and/or administrative services as agents for their customers who beneficially
own Retail Shares. Services provided by such financial institutions may include,
without limitation: printing and distributing advertising and sales literature
and reports to shareholders used in connection with the sale of a Portfolio's
shares, and personnel and communication equipment used in servicing shareholder
accounts and prospective shareholder inquiries.
    
 
                                       4
<PAGE>
     The Conestoga 12b-1 Plan is a 'compensation' type plan as opposed to a
'reimbursement' type plan. Accordingly, payments by Retail Shares under the
Conestoga 12b-1 Plan are based on the expressed fee rather than on the specific
amounts expended by SFS for distribution purposes. SFS may be able to recover
such amounts or may earn a profit from payments made by Retail Shares of
Conestoga under the Conestoga 12b-1 Plan.
 
     For the fiscal year ended October 31, 1995, Conestoga paid, in the
aggregate, fees to SFS pursuant to the Distribution and Services Plan of
$35,000, which represent 0.15% of the Conestoga Portfolios' Retail Shares
average net assets during that period.

this Combined Proxy/Prospectus, which are incorporated herein by reference, for
additional information on CoreFunds' administrator.
 
     State Street Bank and Trust Company serves as CoreFunds' transfer and
dividend disbursing agent. For these services, State Street Bank and Trust
Company receives fees based on annual per shareholder account charges for
account maintenance and fees for certain shareholder-generated transactions,
plus out-of-pocket expenses. The minimum annual transfer agency fee for each
class of each Portfolio is $15,000. See 'Administrator' in the CoreFunds'
Prospectuses accompanying this Combined Proxy/Prospectus, which are incorporated
herein by reference, for additional information on CoreFunds' transfer agent.
 
     Custodial services are provided to CoreFunds by CoreStates Bank, N.A. See
'Custodian and Transfer Agent' in CoreFunds' Statement of Additional
Information, which is incorporated herein by reference, for additional
information about CoreFunds' custodian.
 
   
     SFS serves as distributor of the shares of CoreFunds' Portfolios. CoreFunds
has adopted a Distribution Plan pursuant to Rule 12b-1 under the 1940 Act (the
'CoreFunds 12b-1 Plan'). Under the CoreFunds 12b-1 Plan, the class of shares
known as the Individual Shares of each of the CoreFunds' Portfolios bears the
expense of distribution fees payable to SFS at an annual rate of up to .25% of
the average daily net asset value of such Portfolio's outstanding Individual
Shares to finance activities which are principally intended to result in the
sale of Individual Shares. SFS may enter into agreements with financial
institutions and industry professionals which provide distribution and/or
administrative services as agents for their customers who beneficially own
Individual Shares. Services provided by such financial institutions may include,
without limitation: printing and distributing advertising and sales literature
and reports to shareholders used in connection with the sale of a Portfolio's
shares, and personnel and communication equipment used in servicing shareholder
accounts and prospective shareholder inquiries.
    
 
     The CoreFunds 12b-1 Plan is a 'compensation' type plan as opposed to a
'reimbursement' type plan. Accordingly, payments by Individual Shares under the
CoreFunds 12b-1 Plan are based on the expressed fee rather than on the specific
amounts expended by SFS for distribution purposes. SFS may be able to recover
such amounts or may earn a profit from payments made by Individual Shares of
CoreFunds under the CoreFunds 12b-1 Plan.
 
     For the fiscal year ended June 30, 1995, CoreFunds paid, in the aggregate,
fees to SFS pursuant to the Distribution Plan of $120,490, which represent 0.25%
of the CoreFunds' Portfolios Individual Shares average net assets during that
period.

     COMPARATIVE FEE AND EXPENSE TABLES.  The tables below show (i) information
regarding the fees and expenses paid by each class of shares of each Conestoga
Portfolio and of each class of shares of each CoreFunds Portfolio as of their
most recent fiscal years, restated to reflect expenses the Conestoga Portfolio
and the CoreFunds Portfolio, respectively, expect to incur during the current
fiscal year and (ii) estimated fees and expenses on a pro forma basis giving
effect to the proposed Reorganization. The investment adviser and other service
providers for CoreFunds are not contractually obligated to do so, but certain of
them have informed CoreFunds and Conestoga that they expect to waive fees and
reimburse expenses for the twelve months following the Reorganization as
necessary to maintain the total operating expenses applicable to each class of
shares of each Portfolio at the pro forma levels stated in the tables below. The
tables indicate that the total operating expenses applicable to each class of
the Conestoga Portfolios are expected to decrease, except those attributable to
the Institutional Shares and Retail Shares of the Conestoga Tax-Free Fund and
the Retail Shares of the Conestoga Special Equity Fund.

*   It is expected that the CoreFunds Value Equity Fund will change its name and
    investment policies upon consummation of the Reorganization and that it will
    continue the operations of the Conestoga Equity Fund.
 
(1) 12b-1 fees for the Retail Shares of the Conestoga Equity Fund have been
    reduced to reflect the voluntary waiver of fees by that Fund's Distributor.
    Conestoga Equity Fund can pay up to 0.40% of the average daily net assets of
    its Retail Shares as a 12b-1 fee to the distributor.
 
   
(2) Under rules of the NASD, a 12b-1 fee may be treated as a sales charge for
    certain purposes. Because the 12b-1 fee is an annual fee charged against the
    assets of a Portfolio, long-term shareholders may indirectly pay more in
    total sales charges than the economic equivalent of the maximum front-end
    sales charge permitted by the rules of the NASD.
    
 
   
(3) Includes administration fees. Absent voluntary fee waivers, administration
    fees are payable at the maximum annual rate of .25% of the Class Y
    (Institutional) Shares and Class A (Individual) Shares of the CoreFunds
    Value Equity Fund, and .17% of the Institutional Shares and Retail Shares of
    the Conestoga Equity Fund.
    
 
   
(4) Other Expenses, before fee waivers and/or expense reimbursements, would have
    been 0.36% and 0.36%, respectively, for the Institutional Shares and Retail
    Shares of the Conestoga Equity Fund.
    
 
   
(5) Other Expenses, before fee waivers and/or expense reimbursements, would have
    been 0.33% and 0.33%, respectively, for the Class Y (Institutional) Shares
    and Class A (Individual) Shares of the CoreFunds Value Equity Fund.
    
 
   
(6) Other Expenses, before fee waivers and/or expense reimbursements, would be
    0.35% and 0.35%, respectively, for the Class Y (Institutional) Shares and
    Class A (Individual) Shares of the Pro Forma Combined Portfolio.
    
 
   
(7) Absent the voluntary waivers and reimbursements by the investment adviser,
    which can be terminated at any time, the total operating expenses of the
    Institutional Shares and Retail Shares of the Conestoga Equity Fund would
    have been 1.10% and 1.50%, respectively.
    
 
   
(8) Absent fee waivers by the investment adviser and administrator, which can be
    terminated at any time, the total operating expenses for Class Y
    (Institutional) Shares and Class A (Individual) Shares of the CoreFunds
    Value Equity Fund would have been 1.08% and 1.33%, respectively.
    
 
   
(9) Absent voluntary waivers, which can be terminated at any time, the total
    operating expenses of the Class Y (Institutional) Shares and Class A
    (Individual) Shares of the Pro Forma Combined Portfolio would be 1.09% and
    1.34%, respectively.

(1) The maximum advisory fee for the Institutional Shares and Retail Shares of
    the Conestoga Special Equity Fund and the Class Y (Institutional) Shares and
    Class A (Individual) Shares of the CoreFunds Special Equity Fund is 1.50%.
    
 
(2) 12b-1 fees for the Retail Shares of the Conestoga Special Equity Fund have
    been reduced to reflect the voluntary waiver of fees by that Fund's

(3) Under rules of the NASD, a 12b-1 fee may be treated as a sales charge for
    certain purposes. Because the 12b-1 fee is an annual fee charged against the
    assets of a Portfolio, long-term shareholders may indirectly pay more in
    total sales charges than the economic equivalent of the maximum front-end
    sales charge permitted by the rules of the NASD.
    
   
(4) Includes administration fees. Absent voluntary fee waivers, administration
    fees are payable at the maximum annual rate of .17% of the Institutional
    Shares and Retail Shares of the Conestoga Special Equity Fund.
    
   
(5) Other Expenses, before fee waivers and/or expense reimbursements, would have
    been 0.37% and 0.37%, respectively, for the Institutional Shares and Retail
    Shares of the Conestoga Special Equity Fund.
    
   
(6) Other Expenses, before fee waivers and/or expense reimbursements, would be
    0.30% and 0.30%, respectively, for the Class Y (Institutional) Shares and
    Class A (Individual) Shares of the CoreFunds Special Equity Fund.
    
   
(7) Absent the voluntary waivers and reimbursements by the investment adviser
    and administrator, which can be terminated at any time, the total operating
    expenses of the Institutional Shares and Retail Shares of the Conestoga
    Special Equity Fund would have been 1.87% and 2.27%, respectively.
    
   
(8) Absent voluntary waivers, which can be terminated at any time, the pro forma
    total operating expenses of the Class Y (Institutional) Shares and Class A
    (Individual) Shares of the CoreFunds Special Equity Fund would be 1.80% and

- ------------------
 
(1) The maximum advisory fee for the Institutional Shares and Retail Shares of
    the Conestoga Pennsylvania Tax-Free Bond Fund is .74%.
 
(2) The maximum advisory fee for the Class Y (Institutional) Shares and Class A
    (Individual) Shares of the CoreFunds Pennsylvania Municipal Bond Fund is
    .50%.
 
(3) 12b-1 fees for the Retail Shares of the Conestoga Pennsylvania Tax-Free Bond
    Fund have been reduced to reflect the voluntary waiver of fees by that
    Fund's distributor. The Conestoga Pennsylvania Tax-Free Bond Fund can pay up
    to .40% of the average daily net assets of its Retail Shares as a 12b-1 fee
    to its distributor.

(4) Under rules of the NASD, a 12b-1 fee may be treated as a sales charge for
    certain purposes. Because the 12b-1 fee is an annual fee charged against the
    assets of a Portfolio, long-term shareholders may indirectly pay more in
    total sales charges than the economic equivalent of the maximum front-end
    sales charge permitted by the rules of the NASD.
    
   
(5) Includes administration fees. Absent voluntary fee waivers, administration
    fees are payable at the maximum annual rate of .25% of the Class Y
    (Institutional) Shares and Class A (Individual) Shares of the CoreFunds
    Pennsylvania Municipal Bond Fund, and .17% of the Institutional Shares and
    Retail Shares of the Conestoga Pennsylvania Tax-Free Bond Fund.
    
   
(6) Other Expenses, before fee waivers and/or expense reimbursements, would have
    been 0.46% and 0.46%, respectively, for the Class Y (Institutional) Shares
    and Class A (Individual) Shares of the CoreFunds Pennsylvania Municipal Bond
    Fund.
    
   
(7) Other Expenses, before fee waivers and/or expense reimbursements, would be
    0.39% and 0.39%, respectively, for the Class Y (Institutional) Shares and
    Class A (Individual) Shares of the Pro Forma Combined Portfolio.
    
   
(8) Absent the voluntary waivers and reimbursements by the investment adviser
    and administrator, which can be terminated at any time, the total operating
    expenses for the Institutional Shares and Retail Shares of the Conestoga
    Pennsylvania Tax-Free Bond Fund would have been 1.25% and 1.65%,
    respectively.
    
   
(9) Absent the voluntary fee waivers by the investment adviser and
    administrator, which can be terminated at any time, total operating expenses
    for the Class Y (Institutional) Shares and Class A (Individual) Shares of
    the CoreFunds Pennsylvania Municipal Bond Fund would have been 0.96% and
    1.21%, respectively.
    
   
(10) Absent voluntary waivers, which can be terminated at any time, the total
     operating expenses for the Class Y (Institutional) Shares and Class A
     (Individual) Shares of the Pro Forma Combined Portfolio would be 0.89% and
     1.14%, respectively.

*    The CoreFunds Short-Term Income Fund has not yet commenced operations. The
     CoreFunds Short-Term Income Fund will continue the operations of the
     Conestoga Short-Term Income Fund upon consummation of the Reorganization
     relating to that Fund. (1) The maximum advisory fee for the Institutional
     Shares and Retail Shares of the Conestoga Short-Term Income Fund and for
     the Class Y (Institutional) Shares and Class A (Individual) Shares of the
     CoreFunds Short-Term Income Fund is .74%

<PAGE>
   

(2)  12b-1 fees for the Retail Shares of the Conestoga Short-Term Income Fund
     have been reduced to reflect the voluntary waiver of fees by that Fund's
     distributor. The Conestoga Short-Term Income Fund can pay up to 0.40% of
     the average daily net assets of its Retail Shares as a 12b-1 fee to the
     distributor.

(3)  Under rules of the NASD, a 12b-1 fee may be treated as a sales charge for
     certain purposes. Because the 12b-1 fee is an annual fee charged against
     the assets of a Portfolio, long-term shareholders may indirectly pay more
     in total sales charges than the economic equivalent of the maximum
     front-end sales charge permitted by the rules of the NASD.

(4)  Includes administration fees. Absent voluntary fee waivers, administration
     fees are payable at the maximum annual rate of .17% of the Institutional
     Shares and Retail Shares of the Conestoga Short-Term Income Fund.

(5)  Other Expenses, before fee waivers and/or expense reimbursements, would be
     0.30% and 0.30%, respectively, for the Class Y (Institutional) Shares and
     Class A (Individual) Shares of the CoreFunds Short-Term Income Fund.

(6)  Absent the voluntary waivers and reimbursements by the investment adviser
     and administrator, which can be terminated at any time, the total operating
     expenses for the Institutional and Retail Shares of the Conestoga
     Short-Term Income Fund would be 1.08% and 1.48%, respectively.

(7)  Absent voluntary waivers, which can be terminated at any time, the pro
     forma total operating expenses of the Class Y (Institutional) Shares and
     Class A (Individual) Shares of the CoreFunds Short-Term Income Fund would
     be 1.04% and 1.29%, respectively.

    
 
     EXAMPLE: An investor would pay the following expenses on a $1,000
     investment, assuming (1) 5% annual return, and (2) redemption at the end of
     the following periods:

     VOTING INFORMATION.  This Combined Proxy Statement/Prospectus is being
furnished in connection with the solicitation of proxies by Conestoga's Board of
Trustees in connection with a Special Meeting of Shareholders to be held at The
Wilmington Hilton, 630 Naamans Road, Wilmington, Delaware, on Friday, March 22,
1996 at 10:00 a.m. Eastern time (such meeting and any adjournments thereof
hereinafter referred to as the 'Meeting'). Only Shareholders of record at the
close of business on January 26, 1996 will be entitled to notice of and to vote
at the Meeting. Each share or fraction thereof is entitled to one vote or
fraction thereof and all shares will vote separately by Portfolio. Shares
represented by a properly executed proxy will be voted in accordance with the
instructions thereon, or if no specification is made, the persons named as
proxies will vote in favor of each proposal set forth in the Notice of Meeting.
Proxies may be revoked at any time before they are exercised by submitting to
Conestoga a written notice of revocation or a subsequently executed proxy or by
attending the Meeting and voting in person. For additional information,
including a description of the Shareholder vote required for approval of the
Reorganization Agreement and related transactions contemplated thereby,
including the approval of the interim investment advisory and sub-advisory
agreements, see 'Information Relating to Voting Matters.'
    
 
   
     RISK FACTORS.  The following discussion highlights the principal risk
factors associated with an investment in the Reorganizing Portfolios and the
Existing CoreFunds Portfolios and is qualified in its entirety by the more
extensive discussion of risk factors in 'Comparison of Investment Policies and
Risk Factors.'
    
 
   
     Because of the similarities of the investment objectives and policies of
the Reorganizing Portfolios and the corresponding Existing CoreFunds Portfolios,
management believes that an investment in an Existing CoreFunds Portfolio
involves risks that are similar to those of the corresponding Reorganizing
Portfolio. These investment risks include those typically associated with
investing in a portfolio of high quality, short-term money market instruments in
the case of the money market portfolios; government or investment grade bonds in
the case of the taxable and tax-exempt bond portfolios; common stocks in the
case of the stock portfolios; and foreign securities in the case of the
international portfolios.
    
 
   
     There are differences, however, between the Reorganizing Portfolios and the
Existing CoreFunds Portfolios as noted above under 'Summary -- Overview of the
Conestoga Portfolios and the CoreFunds Portfolios' and below under 'Comparison
of Investment Policies and Risk Factors.' These differences can result in
different risks. For example, the Conestoga Tax-Free Fund may invest in
securities with lower credit ratings than CoreFunds Tax-Free Reserve. In
addition, unlike the Existing CoreFunds Portfolios, the Reorganizing Portfolios
may invest their assets in securities rated in the lowest investment grade
rating category. Debt securities with the lowest investment grade rating do not
have outstanding investment characteristics and may have speculative
characteristics as well.
    
 
   
     Although the money market portfolios offered by both Conestoga and
CoreFunds seek to maintain a stable net asset value of $1.00 per share, there is
no assurance they will be able to do so. The per share price of the other
portfolios will fluctuate with changes in value of the investments held by each
portfolio. Generally, the market value of debt securities will vary inversely to
changes in prevailing interest rates. Certain portfolios may seek to achieve
their investment objectives through investments in securities of foreign issuers
that involve risks not typically associated with U.S. issuers; debt instruments
with the lowest investment grade rating which are speculative; mortgage-backed
and asset-backed securities; illiquid instruments; and certain options, futures
and foreign currency transactions. Some of the Conestoga fixed-income and equity
portfolios may have higher portfolio turnover rates, resulting in higher
portfolio costs. Both the Reorganizing Portfolios and the Existing CoreFunds
Portfolios may engage in the use of reverse repurchase agreements that can cause
their net asset values
    
 
                                       28
<PAGE>

to rise or fall faster than they otherwise would. Reverse repurchase agreements
involve the risk that the market value of the securities sold by a portfolio may
decline below the price of the securities the portfolio is obligated to
purchase. The policy of CoreFunds Tax-Free Reserve, Conestoga Pennsylvania
Tax-Free Bond Fund and CoreFunds Pennsylvania Municipal Bond Fund to invest
primarily in municipal obligations of Pennsylvania and the non-diversified
status of Conestoga Pennsylvania Tax-Free Bond Fund and CoreFunds Pennsylvania
Municipal Bond Fund, present additional risks as stated in their current
prospectuses. There is no assurance that any portfolio will achieve its
investment objective.
 
              INFORMATION RELATING TO THE PROPOSED REORGANIZATION
 
   
     Conestoga has entered into an agreement whereby its investment portfolios
are to be acquired by portfolios of CoreFunds. Significant provisions of this
Reorganization Agreement are summarized below; however, this summary is
qualified in its entirety by reference to the Reorganization Agreement, a copy
of which is attached as Appendix I to this Combined Proxy Statement/Prospectus.
    
 
   
     DESCRIPTION OF THE REORGANIZATION AGREEMENT.  There are eleven separate
Conestoga investment portfolios. Initially the assets of eight of them will be
acquired by eight similar investment portfolios currently offered by CoreFunds.
Subsequently, three portfolios will be acquired by three new CoreFunds
portfolios which have been organized to continue the operations of these
Conestoga Portfolios.
    
 
   
     The Reorganization Agreement provides, first, that substantially all of the
assets and liabilities of the Reorganizing Portfolios will be transferred to the
Existing CoreFunds Portfolios identified in the table below. Not less than seven
calendar days thereafter, substantially all of the assets and liabilities of the
Continuing Portfolios will be transferred to the New CoreFunds Portfolios
identified in the table below. The holders of each class of shares of a
Conestoga Portfolio will receive the class of shares of the corresponding
CoreFunds Portfolio identified in the table. In the tables, (a) opposite the
name of each Conestoga Portfolio is the name of the CoreFunds Portfolio which
will issue shares to such Conestoga Portfolio, and (b) opposite the name of each
class of shares of the Conestoga Portfolio is the name of the class of shares of
the CoreFunds Portfolio to be distributed to the holders of such Conestoga
class. The number of each class of shares to be issued by the CoreFunds
Portfolios will have an aggregate net asset value equal to the aggregate net
asset value of the corresponding class or classes of shares of the particular
Conestoga Portfolio as of the regular close of the New York Stock Exchange,
currently 4:00 p.m. New York time, on the business day immediately preceding
each transaction. The three CoreFunds money market portfolios (Cash Reserve,
Tax-Free Reserve and Treasury Reserve) may have minute differences in
market-based net asset values per share from their Conestoga counterparts;
however, it is a condition of the Reorganization that the per-share amortized
cost values of these portfolios be identical with those of the Conestoga money
market portfolios.

     Conestoga expects to liquidate a limited number of holdings of certain of
the Conestoga Portfolios in light of the investment policies of CoreFunds and
the strategies of its investment adviser. Similarly, CoreFunds Value Equity Fund
expects to liquidate a limited number of holdings in light of its intention to
change its investment policies to resemble those of Conestoga Equity Portfolio.
The transaction costs that will result from such sales are expected to be
minimal.
   
     The Reorganization Agreement provides that Conestoga will declare a
dividend or dividends prior to the Reorganizing Portfolios Transactions which,
together with all previous dividends, will have the effect of distributing to
the Shareholders of each of the Reorganizing Portfolios all undistributed
ordinary income earned and net capital gains realized up to and including the
effective time of the Reorganization.
    
 
   
     Following the transfers of assets and liabilities from the Conestoga
Portfolios to the CoreFunds Portfolios, and the issuances of shares by the
CoreFunds Portfolios to the Conestoga Portfolios, each of the Conestoga
Portfolios will distribute the class of shares of the CoreFunds Portfolios pro
rata to the holders of classes of shares of the Conestoga Portfolios as
described above in liquidation of the Conestoga Portfolios. Each holder of a
class of shares of a Conestoga Portfolio will receive an amount of the
corresponding class of shares of the corresponding CoreFunds Portfolio of equal
value, plus the right to receive any declared and unpaid dividends or
distributions. Following the Reorganization, the registration of Conestoga as an
investment company under the 1940 Act will be terminated, and Conestoga will be
terminated under state law.
    
 
   
     The stock transfer books of Conestoga will be permanently closed after the
Reorganization.
    
 
   
     The Reorganization is subject to a number of conditions, including approval
of the Reorganization Agreement and the transactions contemplated thereby
described in this Combined Proxy Statement/Prospectus by the Shareholders of
Conestoga; the receipt of certain legal opinions described in the Reorganization
Agreement; the receipt of certain certificates from the parties concerning the
continuing accuracy of the representations and warranties in the Reorganization
Agreement and other matters; and the parties' performance in all material
respects of their agreements and undertakings in the Reorganization Agreement.
Assuming satisfaction of the conditions in the Reorganization Agreement, the
Reorganization Portfolios Transaction is expected to occur on or after April 8,
1996 and the Continuing Portfolios Transaction is expected to occur on or after
April 15, 1996.
    
 
   
     The expenses of CoreFunds and of Conestoga incurred in connection with the
Reorganization will be borne by CoreStates Financial Corp and/or Meridian
Bancorp., Inc., except that the CoreFunds shall bear any registration fees
payable under the Securities Act of 1933 and state 'blue sky' laws, and
Conestoga shall bear any custody termination fees it incurs.

     The Reorganization may be abandoned prior to its consummation by the mutual
consent of the parties to the Reorganization Agreement. The Reorganization
Agreement provides further that at any time prior to or (to the fullest extent
permitted by law) after approval of the Reorganization Agreement by the
Shareholders of Conestoga (a) the parties thereto may, by written agreement
approved by their respective Boards of Trustees or Directors, or authorized
officers and with or without the approval of their Shareholders, amend any of
the provisions of the Reorganization Agreement; and (b) either party may waive
any breach by the other party or the failure to satisfy any of the conditions to
its obligations with or without the approval of such party's shareholders.
    
 
     The Reorganization Agreement also provides that the Reorganization will be
contingent upon the consummation of the Holding Company Merger.
 
   
     In its consideration and approval of the Reorganization at a meeting on
December 21, 1995, the Board of Trustees of Conestoga considered, primarily, the
pending merger between Meridian Bancorp, Inc., the parent company of MIC, and
CoreStates Financial Corp. If this merger is completed, the currently existing
investment advisory contract between Conestoga and MIC would be terminated.
Given that fact, MIC and CoreStates Advisers have recommended that each of the
Conestoga Portfolios be reorganized as described in this Combined Proxy
Statement/Prospectus shortly after the proposed merger of the bank holding
companies. The Board of Trustees of Conestoga considered the effect of the
proposed merger of the bank holding companies on Conestoga; the recommendation
of MIC and CoreStates Advisers with respect to the proposed consolidation of
Conestoga and CoreFunds; the fact that the Reorganization would constitute a
tax-free reorganization; and that the interests of Shareholders would not be
diluted as a result of the Reorganization.
    
 
   
     Section 15(f) of the 1940 Act provides that when a change in the control of
an investment adviser occurs, the investment adviser or any of its affiliated
persons may receive any amount or benefit in connection therewith under certain
conditions. One condition is that for three years thereafter, at least 75% of
the board of directors of a surviviving investment company are not 'interested
persons' of the company's investment adviser or of the investment adviser of the
terminating investment company. Another condition is that no 'unfair burden' is
imposed on the investment company as a result of the transaction relating to the
change of control, or any express or implied terms, conditions or understandings
applicable thereto. The term 'unfair burden' as defined in the 1940 Act includes
any arrangement during the two-year period after the transaction whereby the
investment adviser (or predecessor or successor adviser), or any 'interested
person' of any such adviser, receives or is entitled to receive any
compensation, directly or indirectly, from the investment company or its
security holders (other than fees for bona fide investment advisory or other
services) or from any person in connection with the purchase or sale of
securities or other property to, from or on behalf of the investment company
(other than fees for bona fide principal underwriting services). CoreFunds
intends to comply with the conditions set forth in Section 15(f)
    
 
     After consideration of all of the foregoing factors, together with certain
other factors and information considered to be relevant, Conestoga's Trustees
unanimously approved the Reorganization Agreement and directed that it be
submitted to shareholders for approval. CONESTOGA'S BOARD OF TRUSTEES RECOMMENDS
THAT SHAREHOLDERS VOTE 'FOR' APPROVAL OF THE REORGANIZATION AGREEMENT.
 
     The Board of Trustees of Conestoga has not determined what action it will
take in the event the shareholders of any Conestoga Portfolio fail to approve
the Reorganization Agreement or for any reason the Reorganization is not
consummated. In either such event, the Trustees may choose to consider approval
of a new investment advisory agreement with CoreStates Advisers, alternative
dispositions of Conestoga's assets, including the sales of assets to, or merger
with, another investment company, or the possible liquidation of any of its
Portfolios.

     At a meeting held on December 7, 1995, the CoreFunds Board of Directors
considered the proposed Reorganization. Based upon their evaluation of the
relevant information provided to them, and in light of their fiduciary duties
under federal and state law, the Board of Directors unanimously determined that
the proposed Reorganization was in the best interests of CoreFunds and their
respective shareholders and that the interests of existing shareholders of
CoreFunds would not be diluted as a result of effecting the transaction.
    
 
   
     CAPITALIZATION.  Because the Reorganizing Portfolios will be combined in
the Reorganization with the Existing CoreFunds Portfolios, the total
capitalization of each of the Existing CoreFunds Portfolios after the
Reorganization is expected to be greater than the current capitalization of the
corresponding Reorganizing Portfolios. The following table sets forth as of
October 31, 1995, (i) the capitalization of each of the Reorganizing Portfolios
and (ii) the pro forma capitalization of each of the Existing CoreFunds
Portfolios as adjusted to give effect to the Reorganization. If consummated, the
capitalization of each Portfolio is likely to be different at the time of the
Reorganizing Portfolios Transaction as a result of daily share purchase and
redemption activity in the Portfolios.

     FEDERAL INCOME TAX CONSEQUENCES.  Consummation of the Reorganization is
subject to the condition that Conestoga and CoreFunds receive an opinion from
Morgan, Lewis & Bockius LLP to the effect that for federal income tax purposes:
(i) the transfer of all of the assets and liabilities of each of the
Reorganizing Portfolios (except in each case for a cash reserve in an amount
necessary for the discharge of all known and reasonably anticipated liabilities
of each of the Reorganizing Portfolios) and each of the Continuing Funds to the
corresponding CoreFunds Portfolio in exchange for shares of the corresponding
CoreFunds Portfolio and liquidating distributions to Shareholders of the
Conestoga Portfolios of the shares of the CoreFunds Portfolio so received, as
described in the Reorganization Agreement, will constitute reorganizations
within the meaning of Section 368(a)(1)(C), Section 368(a)(1)(D) or Section
368(a)(1)(F) of the Internal Revenue Code of 1986, as amended, and with respect
to the Reorganization, each Conestoga Portfolio and CoreFunds Portfolio will be
considered 'a party to a reorganization' within the meaning of Section 368(b) of
the Code; (ii) no gain or loss will be recognized by the Conestoga Portfolios as
a result of such transactions; (iii) no gain or loss will be recognized by the
CoreFunds Portfolios as a result of such transactions; (iv) no gain or loss will
be recognized by the Shareholders of any Conestoga Portfolio on the distribution
to them by Conestoga of shares of any Class of the corresponding CoreFunds
Portfolio in exchange for their shares of any class of the Conestoga Portfolio;
(v) the aggregate basis of the CoreFunds Portfolio shares received by a
shareholder of a Conestoga Portfolio will be the same as the aggregate basis of
the Shareholder's Conestoga Portfolio shares immediately prior to the
Reorganization; (vi) the basis of each CoreFunds Portfolio in the assets of the
corresponding Conestoga Portfolio received pursuant to the Reorganization will
be the same as the basis of the assets in the hands of the Conestoga Portfolio
immediately before the Reorganization; (vii) a shareholder's holding period for
CoreFunds Portfolio shares will be determined by including the period for which
the shareholder held the Conestoga Portfolio shares exchanged therefor, provided
that the shareholder held such Conestoga Portfolio shares as a capital asset;
and (viii) each CoreFunds Portfolio's holding period with respect to the assets
received in the Reorganization will include the period for which such assets
were held by the corresponding Conestoga Portfolio.
    
 
     CoreFunds and Conestoga have not sought a tax ruling from the Internal
Revenue Service ('IRS'), but are acting in reliance upon the opinion of counsel
discussed in the previous paragraph. That opinion is not binding on the IRS and
does not preclude the IRS from adopting a contrary position. Shareholders should
consult their own advisers concerning the potential tax consequences to them,
including state and local income taxes.
               COMPARISON OF INVESTMENT POLICIES AND RISK FACTORS
 
   
     The investment objectives and policies of the Reorganizing Portfolios are,
in many respects, similar to those of the corresponding Existing CoreFunds
Portfolios. There are, however, certain differences. The following discussion
summarizes some of the more significant similarities and differences in the
investment policies and risk factors of the Reorganizing Portfolios and
corresponding Existing CoreFunds Portfolios and is qualified in its entirety by
the discussion elsewhere herein, and in the prospectuses and statements of
additional information of the Reorganizing Portfolios and the
    
 
                                       35
<PAGE>
Existing CoreFunds Portfolios incorporated herein by reference.
 
CONESTOGA CASH MANAGEMENT FUND AND COREFUNDS CASH RESERVE
 
     Each Fund is a money market fund that seeks to maintain a net asset value
of $1.00 per share, although there is no assurance either will be able to do so.
Both the Conestoga Cash Management Fund and CoreFunds Cash Reserve may invest in
a broad range of U.S. dollar-denominated, high quality, short-term instruments,
including government obligations, commercial paper, asset-backed securities,
bank obligations and repurchase agreements.
 
     Both Funds may invest their assets in securities that are rated in the
highest two rating categories by a nationally recognized statistical rating
organization (a 'Rating Agency'), provided that investments in securities that
are not 'First Tier Securities' (as defined below) may not exceed 5% of their
assets, and investments in securities of any single issuer that is not 'First
Tier' may not exceed the greater of 1% of a Fund's total assets or $1 million.
'First Tier Securities' are securities that (i) are rated in the highest rating
category by a Rating Agency; (ii) are rated in the highest rating category by at
least two Rating Agencies, if rated by more than one Rating Agency; (iii) have
no short-term rating, but have been issued by an issuer that has other
outstanding short-term obligations that have been so rated and are of comparable
quality; and (iv) are unrated but have been determined to be of comparable
quality. Commercial paper purchased by either Fund must be rated in the highest
rating category.
 
     Both Funds may invest in 'stripped' U.S. Treasury obligations ('STRIPS'),
may purchase receipts in U.S. Treasury obligations (e.g., 'TIGRs' and 'CATS')
and zero coupon securities. These securities may exhibit greater price
volatility than ordinary debt securities because of the manner in which their
principal and interest are returned to investors. Conestoga Cash Management Fund
may not purchase zero coupon securities if, immediately after such purchase,
more than 5% of its net assets would be invested in such obligations. CoreFunds
Cash Reserve has no explicit limit on its investment in such securities.
 
     Both Funds may invest in U.S. dollar denominated bank obligations of
foreign and domestic banks such as certificates of deposit, time deposits,
bankers' acceptances, Eurodollar Certificates of Deposit, Eurodollar Time
Deposits, Canadian Time Deposits and Yankee Certificates of Deposit.
 
     The Conestoga Cash Management Fund will not invest in excess of 10% of its
total assets in time deposits, including Eurodollar Time Deposits and Canadian
Time Deposits but not including certificates of deposit, with maturities in
excess of seven days which are subject to penalties upon early withdrawal.
CoreFunds Cash Reserve is not bound by this restriction.
 
CONESTOGA U.S. TREASURY SECURITIES FUND AND COREFUNDS TREASURY RESERVE.
 
     Each Fund is a money market fund that seeks to maintain a net asset value
of $1.00 per share, although there is no assurance either will be able to do so.
Both Funds invest exclusively in short-term obligations issued by the U.S.
Treasury, including STRIPS, some of which may be subject to repurchase
agreements collateralized by the underlying U.S. Treasury obligations.
 
CONESTOGA TAX-FREE FUND AND COREFUNDS TAX-FREE RESERVE
 
     Each Fund is a money market fund that seeks to maintain a net asset value
of $1.00 per share, although there is no assurance they will be able to do so.
Both Funds invest at least 80% of their assets in municipal securities, the
interest on which is both exempt from regular Federal income tax and is not an
item of tax preference for purposes of the Federal alternative minimum tax.
 
     Conestoga Tax-Free Fund may invest in securities rated in the two highest
rating categories by a Rating Agency, or, if unrated, are determined to be of
comparable quality. CoreFunds Tax-Free Reserve's investments in securities that
are not 'First Tier Securities' may not exceed 5% of its assets, and investment
in securities of any single issuer that is not 'First Tier' may not exceed the
greater of 1% of the Fund's total assets of $1 million.
 
                                       36
<PAGE>
     Both Funds invest in the same types of municipal securities. Both are
permitted to invest up to 20% of their total assets in taxable obligations for
temporary defensive purpose or when sufficient tax-exempt securities are not
available. Conestoga Tax-Free Fund's investment policies permit that Fund to
invest up to 100% of its assets in taxable obligations for temporary defensive
purposes. Taxable obligations eligible for purchase by the Funds include, but
are not limited to obligations of the U.S. Government, its agencies and
instrumentalities, debt securities (including taxable commercial paper) of
issuers having the highest short-term rating assigned by a Rating Agency, bank
obligations, repurchase agreements and reverse repurchase agreements.
 
     Both Funds may enter into when-issued transactions. These transactions are
arrangements in which a fund purchases securities with payment and delivery
scheduled for a future time. The seller's failure to complete these transactions
may cause a fund to miss a price or a yield considered to be advantageous.
Settlement dates may be a month or more after entering into these transactions,
and the market values of the securities purchases may vary from the purchase
prices. Accordingly, a fund may pay more or less than the market value of the
securities on the settlement date. Commitments to purchase when-issued
securities will not exceed 25% of either Fund's total assets and will not be
purchased for speculative purposes.
 
     CoreStates Advisers intends to invest, when possible, the CoreFunds
Tax-Free Reserve's assets in municipal securities, the interest on which is
exempt from Pennsylvania personal income tax ('Pennsylvania Municipal
Securities'), provided the investment is consistent with the Fund's investment
objective, policies and status as a diversified investment company. To the
extent that the Fund's assets are so concentrated in Pennsylvania Municipal
Securities, it would be subject to the peculiar risks presented by the laws and
economic conditions of Pennsylvania to a greater extent than it would be if its
assets were not so concentrated.
 
     CoreFunds Tax-Free Reserve may, unlike Conestoga Tax-Free Fund, invest in
municipal lease obligations. Municipal lease obligations are issued by a state
or local government or authority to acquire land and a wide variety of equipment
and facilities. These obligations typically are not fully backed by the
municipality's credit, and their interest may become taxable if the lease is
assigned. If funds are not appropriated for the following year's lease payments,
the lease may terminate, with the possibility of default on the lease obligation
and significant loss to a Fund. Certificates of participation in municipal lease
obligations or installment sales contracts entitle the holder to a proportionate
interest in the lease-purchase payments made.
 
CONESTOGA EQUITY FUND AND COREFUNDS VALUE EQUITY FUND.
 
     It is expected that the CoreFunds Value Equity Fund will change its name to
'CoreFunds Equity Fund' and adopt investment policies that are substantially
identical to Conestoga Equity Fund at the time of the Reorganization.
 
     The investment policies of both Funds are similar. The principal difference
between the policies is that under normal market condition, 80% of the Conestoga
Equity Fund's assets will be invested in common stock whereas CoreFunds Value
Equity Fund is only required to hold 75% of its assets in equity securities
which may include common stock. CoreFunds Value Equity Fund has a broader range
of eligible investments which include common stocks, preferred stocks and
convertible securities. Both Funds may invest portions of their assets in
short-term and fixed income vehicles. There are differences in the quality of
the debt investments each Fund may make. Conestoga Equity Fund may invest in
fixed income securities rated in the four highest rating categories by a Rating
Agency whereas CoreFunds Value Equity Fund is limited to fixed income securities
rated in the highest rating category. Similarly, short-term debt securities
invested in by Conestoga Equity Fund may be rated in the two highest rating
categories by a Rating Agency whereas CoreFunds Value Equity is limited to
short-term debt securities rated in the highest rating category.
 
     Conestoga Equity Fund may also purchase put and call options on securities
for the purposes of hedging against market risks related to its portfolio
securities. Such put and call options must be listed on a national securities
exchange and may not exceed 5% of the Fund's net assets. Purchasing options
 
                                       37
<PAGE>
is a specialized investment technique that entails a substantial risk of a
complete loss of the amounts paid as premiums to writers of options. Conestoga
Equity Fund may also engage in writing call options. Conestoga Equity Fund will
write only covered call options (options on securities owned by the Fund).
Conestoga Equity Fund will forego any capital appreciation above the exercise
price on securities on which it has written a call option. In order to close out
a call option it has written, Conestoga Equity Fund will enter into a 'closing
purchase transaction' -- the purchase of a call option on the same security with
the same exercise price and expiration date as the call option which the Fund
previously wrote on a particular security. When a portfolio security subject to
a call option is sold, Conestoga Equity Fund will effect a closing purchase
transaction to close out any existing call option on that security. If Conestoga
Equity Fund is unable to effect a closing purchase transaction, it will not be
able to sell the underlying security until the option expires or the Fund
delivers the underlying security upon exercise. Under normal conditions, it is
not expected that the underlying value of portfolio securities subject to such
options would exceed 50% of the net assets of Conestoga Equity Fund. CoreFunds
Value Equity Fund, as a matter of fundamental policy, is not permitted to engage
in options transactions.
 
     Conestoga Equity Fund may invest in the securities of foreign issuers by
acquiring both sponsored and unsponsored American Depositary Receipts ('ADRs').
ADRs are receipts issued by a bank or trust company in the United States
evidencing ownership of underlying securities of a foreign issuer. Unsponsored
ADRs are organized independently and without the cooperation of the issuer of
the underlying securities. As a result, available information concerning the
issuer may not be as current as for sponsored ADRs, and the prices of
unsponsored ADRs may be more volatile than if such instruments were sponsored by
the issuer. Conestoga Equity Fund may also invest in securities issued by
foreign branches of U.S. banks and foreign banks, in Canadian commercial paper,
and in Europaper (U.S. dollar-denominated commercial paper of a foreign issuer).
By contrast, CoreFunds Value Equity Fund is not expressly permitted to invest in
securities of foreign issuers and may only invest in short-term debt obligations
of domestic branches of U.S. banks.
 
     For many foreign securities, U.S. dollar-denominated ADRs, which are traded
in the United States on exchanges or over-the-counter, are issued by domestic
banks. ADRs represent the right to receive securities of foreign issuers
deposited in a domestic bank or a correspondent bank. ADRs do not eliminate the
risk inherent in investing in the securities of foreign issuers. However, by
investing in ADRs rather than directly in stock of foreign issuers, the
Conestoga Equity Fund can avoid currency risks during the settlement period for
either purchases or sales. In general, there is a large, liquid market in the
United States for many ADRs. The information available for ADRs is subject to
the accounting, auditing and financial reporting standards of the domestic
market or exchange on which they are traded, which standards are more uniform
and more exacting than those to which many foreign issuers may be subject.
Conestoga Equity Fund may also invest in European Depositary Receipts, or EDRs,
which are receipts evidencing an arrangement with a European bank similar to
that for ADRs and are designed for use in the European securities markets. EDRs
are not necessarily denominated in the currency of the underlying security.
 
     Certain ADRs and EDRs, typically those denominated as unsponsored, require
the holders thereof to bear most of the costs of such facilities while issuers
of sponsored facilities normally pay more of the costs thereof. The depositary
of an unsponsored facility frequently is under no obligation to distribute
shareholder communications received from the issuer of the deposited securities
or to pass through the voting rights to facility holders in respect to the
deposited securities, whereas the depositary of a sponsored facility typically
distributes shareholder communications and passes through the voting rights.
 
     Investment in securities of foreign issuers involves certain risks not
ordinarily associated with investments in securities of domestic issuers. Such
risks include fluctuations in foreign exchange rates, difficulties in predicting
international trade patterns, political, social and economic instability in the
country of the issuer, foreign trading practices (including higher trading
commissions, custodial charges and delayed settlements), foreign withholding and
income taxation, the possible establishment of exchange controls or the adoption
of other foreign governmental restrictions (which might adversely
 
                                       38
<PAGE>
affect the payment of principal and interest), difficulty in obtaining and
enforcing judgments against foreign issuers, and the possible imposition of
exchange controls or other foreign governmental laws or restrictions. With
respect to certain countries, there is also the possibility of expropriation of
assets, nationalization of assets, limits on removal of currency or other
assets, confiscatory taxation, political or social instability or diplomatic
developments which could adversely affect investments in those countries.
 
     Foreign companies generally are not subject to uniform accounting, auditing
and financial reporting standards comparable to those applicable to U.S.
domestic companies. There is generally less government regulation of securities
exchanges, brokers and listed companies abroad than in the U.S. Confiscatory
taxation or diplomatic developments could also affect investment in those
countries. In addition, foreign branches of U.S. banks, foreign banks and
foreign issuers may be subject to less stringent reserve requirements and to
different accounting, auditing, reporting, and recordkeeping standards than
those applicable to domestic branches of U.S. banks and U.S. domestic issuers.
 
CONESTOGA INTERMEDIATE INCOME FUND AND COREFUNDS INTERMEDIATE BOND FUND
 
   
     It is expected that the CoreFunds Intermediate Bond Fund will change its
name to 'CoreFunds Short Intermediate Bond Fund' prior to the Reorganization.
    
 
     The investment policies of these Funds are similar. The principle
difference is that Conestoga Intermediate Income Fund will normally invest 80%
of its total assets in debt securities of all types whereas CoreFunds
Intermediate Bond Fund intends, under normal market conditions, to invest 65% of
its total assets in bonds and 35% or less in other debt securities. Both Funds
are permitted to have an average weighted maturity of three to ten years,
however, CoreFunds Intermediate Bond Fund currently maintains a maximum average
maturity of no more than five years pursuant to a non-fundamental investment
policy which can be changed without shareholder approval. CoreFunds expects to
present to the shareholders of the Intermediate Bond Fund a change in
fundamental policy requiring the Fund to have an average weighted maturity
between one and five years. The types of debt securities eligible for investment
by both Funds are the same, with the exception that debt securities in Conestoga
Intermediate Bond Fund may be rated in the four highest rating categories by a
Rating Agency whereas CoreFunds Intermediate Bond Fund is limited to investments
in the three highest rating categories.
 
CONESTOGA PENNSYLVANIA TAX-FREE BOND FUND AND COREFUNDS PENNSYLVANIA MUNICIPAL
BOND FUND
 
     The Funds have similar, but not identical, investment policies. Since both
invest primarily in Pennsylvania Municipal Securities, the Funds are subject to
the risk that the value of their shares may be especially affected by factors
pertaining to the economy of Pennsylvania and the ability of issuers of
Pennsylvania Municipal Securities to meet their obligations. Both Funds are
classified as non-diversified investment companies under the 1940 Act, which
means that since a relative high percentage of assets of each Fund may be
invested in the obligations of a limited number of issuers, the value of the
shares of a Fund may be more susceptible to any single economic, political or
regulatory occurrence then shares of a diversified investment company.
 
     Both Funds invest 80% of their total assets in municipal securities, the
interest on which is exempt from federal income tax. Conestoga Pennsylvania
Tax-Free Bond Fund normally invests at least 80% of its total assets in
Pennsylvania Municipal Securities whereas the policies of CoreFunds Pennsylvania
Municipal Bond Fund state that it is only required to invest 65% of its total
assets in Pennsylvania Municipal Securities.
 
     Conestoga Pennsylvania Tax-Free Bond Fund may invest in debt obligations
rated in one of the four highest rating categories by a Rating Agency, whereas
CoreFunds Pennsylvania Municipal Bond Fund may only purchase securities rated in
one of the three highest rating categories. CoreStates Advisers, however, does
have the discretion to permit it to invest 20% of the Fund's assets in municipal
securities rated in the fourth highest category. Both Funds may invest in
municipal notes.
 
                                       39
<PAGE>
CoreFunds Pennsylvania Municipal Bond Fund may invest in municipal notes rated
in one of the two highest rating categories by a Rating Agency whereas Conestoga
Pennsylvania Tax-Free Bond Fund is limited to municipal notes in the highest
rating category. Both Funds may invest in when-issued securities and municipal
leases. See 'Comparison of Investment Policies and Risk Factors -- Conestoga
Tax-Free Fund and CoreFunds Tax-Free Reserve' for a discussion of when-issued
securities and municipal leases.
 
CONESTOGA BALANCED FUND AND COREFUNDS BALANCED FUND
 
     The investment policies of these Funds are similar. The principal
difference is that Conestoga Balanced Fund invests at least 30% of its total
assets in fixed income securities and no more than 80% in equity securities,
whereas CoreFunds Balanced Fund is required to invest only 25% of its total
assets in fixed income securities with the remainder in common stocks. Fixed
income securities acquired by Conestoga Balanced Fund are rated in one of the
four highest rating categories by a Rating Agency whereas fixed income
securities acquired by CoreFunds Balanced Fund must be rated in one of the three
highest rating categories. The equity and fixed income securities eligible for
purchase by both Funds are substantially the same. Both Funds may invest in
securities of foreign issuers using ADRs. See 'Comparison of Investment Policies
and Risk Factors -- Conestoga Equity Fund and CoreFunds Value Equity Fund' for a
description of ADRs and the risk factors of investment in foreign issuers.
 
CONESTOGA INTERNATIONAL EQUITY FUND AND COREFUNDS INTERNATIONAL GROWTH FUND
 
     The investment policies of both Funds are similar. Conestoga International
Equity Fund invests at least 65% of its assets in an internationally diversified
portfolio of equity securities and may invest up to 35% of its assets in U.S.
companies. CoreFunds International Growth Fund has the same 65% diversification
requirement but has no express statement as to permissible investments in U.S.
companies. Both Funds intend to invest at least 65% of their total assets in
securities traded in at least three foreign countries.
 
   
     Both Funds invest directly in the securities of foreign issuers. Direct
investments in foreign securities generally involve higher costs than
investments in U.S. securities, including higher transaction costs as well as
the imposition of additional taxes by foreign governments. In addition, foreign
investments may include additional risks associated with currency exchange
rates, less complete financial information about the issuers, less market
liquidity and political instability. See 'Comparison Investment Policies and
Risk Factors -- Conestoga Equity Fund and CoreFunds Value Equity Fund' for a
discussion of ADRs and the risk factors of investment in foreign issuers. In
furtherance of their investment objectives, each Fund may engage in foreign
currency transactions including forward currency contracts, futures, contracts
or options transactions. The principal difference is that Conestoga
International Equity Fund may only purchase puts and calls up to 5% of its net
assets and write covered calls up to 50% of its net assets whereas CoreFunds
International Growth Fund may purchase, write or sell options on securities
(including puts and calls) only to the extent obligations under such
transactions represent not more than 20% of its total assets.
    
 
INVESTMENT POLICIES AND RISKS -- GENERAL
 
     The investment objective of each of the Conestoga Cash Management Fund,
Tax-Free Fund, U.S. Treasury Securities Fund, Equity Fund, Special Equity Fund,
Bond Fund, Intermediate Income Fund, Pennsylvania Tax-Free Bond Fund and of each
of the Existing CoreFunds Portfolios is fundamental, meaning that it may not be
changed without a vote of the holders of a majority of the Fund's outstanding
shares, as defined by the 1940 Act. The investment objective of each of the
Conestoga International Equity Fund, Short-Term Income Fund and Balanced Fund is
not fundamental and may be changed by Conestoga's Board of Trustees. The
investment policies of the Conestoga Portfolios and CoreFunds are not
fundamental and may be changed by the respective Board of Trustees and
Directors.
 
   
     This section describes certain policies and risks that are common to a
number of Reorganizing Portfolios and Existing CoreFunds Portfolios.
    
 
                                       40
<PAGE>
   
     Each Reorganizing Portfolio and each Existing CoreFunds Portfolio is
permitted to (i) enter into repurchase agreements and reverse repurchase
agreements; and (ii) purchase obligations of the U.S. Government, its agencies
and instrumentalities. Each Reorganizing Portfolio may invest in bank
obligations of issuers having capital, surplus and undivided profits in excess
of $100 million (as of the date of its most recently published financial
statements) whereas each Existing CoreFund Portfolio may only invest in bank
obligations of domestic branches of U.S. banks having total assets at the time
of purchase of $1 billion.
    
 
   
     Each Reorganizing Portfolio and the CoreFunds Tax-Free Reserve,
Intermediate Bond Fund and Pennsylvania Municipal Bond Fund may enter into
when-issued transactions. See 'Comparison Investment Policies and Risk Factors
- -- Conestoga Tax-Free Fund and CoreFunds Tax-Free Reserve' for a discussion of
the risk factors involved in when-issued transactions.
    
 
     The Conestoga Pennsylvania Tax-Free Bond Fund is permitted to enter into
stand-by commitments with respect to municipal securities. None of the Existing
CoreFunds Portfolios is permitted to participate in these transactions.
 
   
     There are similarities between the Funds with respect to the types of money
market instruments they are permitted to purchase. Each Reorganizing Portfolio
may invest in a broad array of money market instruments, all rated in one of the
top two rating categories by a Rating Agency and (with the exception of
Conestoga Cash Management Fund, U.S. Treasuries Securities Fund and Tax-Free
Fund) may invest in commercial paper rated in the top two rating categories.
Conestoga Cash Management Fund, U.S. Treasury Securities Fund and Tax-Free Fund
may only invest in commercial paper rated in the highest rating category by a
Rating Agency. Each Existing CoreFunds Portfolio may also purchase money market
instruments and commercial paper; the CoreFunds Cash Reserve, Treasury Reserve,
Tax-Free Reserve, Value Equity Fund and International Growth Fund may only
purchase money market instruments and commercial paper that are rated by a
Rating Agency in the highest rating category for such instruments, and the
CoreFunds Balanced Fund, Intermediate Bond Fund and Pennsylvania Municipal Bond
Fund may purchase money market instruments and commercial paper that are within
the two highest rating categories by a Rating Agency.
    
 
     Each of the Conestoga Equity Fund, Intermediate Income Fund, Balanced Fund
and International Equity Fund may lend its portfolio securities. There is no
limit on the amount of securities which these Funds may lend, except that the
Conestoga International Equity Fund may only lend portfolio securities up to
one-third the value of its total assets. Such loans involve risks of delay in
receiving additional collateral or in recovering the securities loaned or even
loss of rights in the collateral, should the borrower of the securities fail
financially. Any portfolio securities purchased with cash collateral would also
be subject to possible depreciation. The Existing CoreFunds Portfolios (with the
exception of CoreFunds International Growth Fund) have a fundamental investment
limitation prohibiting loans.
 
   
     Conestoga Cash Management Fund, Intermediate Income Fund and Balanced Fund
and CoreFunds Cash Reserve and Intermediate Bond Fund may invest in asset-backed
securities. These securities may be backed by either credit card receivables or
motor vehicle installment purchase obligations. Asset-backed securities entail
certain risks, including the risk that credit card receivables are generally
unsecured, and the debtors are entitled to the protection of a number of state
and federal consumer credit laws, many of which give such debtors the right to
set off certain amounts owned on the credit cards, thereby reducing the balance
due. Most issuers of asset-backed securities backed by motor vehicle installment
purchase obligations permit the servicer of such receivable to retain possession
of the underlying obligations. If the servicer sells these obligations to
another party, there is a risk that the purchaser would acquire an interest
superior to that of the holders of the related asset-backed securities. Further,
if a vehicle is registered in one state and is then re-registered because the
owner and obligor move to another state, such re-registration could defeat the
original security interest in the vehicle in certain cases. In addition, because
of the large number of vehicles involved in a typical issuance and technical
requirements under state laws, the trustee for the holders of asset-backed
securities backed by automobile receivables may not have a proper security
interest in all of the obligations backing such receivables. Therefore, there is
the possibility that recoveries on repossessed
    
 
                                       41
<PAGE>
collateral may not, in some cases, be available to support payments on these
securities.
 
     Conestoga Intermediate Income Fund and Balanced Fund and CoreFunds
Intermediate Bond Fund and Balanced Fund may invest in mortgage-backed
securities. To the extent that a Fund purchases mortgage-backed securities at a
premium, mortgage foreclosures and prepayments of principal by mortgagors (which
may be made at any time without penalty) may result in some loss of the Fund's
principal investment to the extent of the premium paid. The yield of a Fund that
invests in mortgage-backed securities may be affected by reinvestment of
prepayments at higher or lower rates than the original investment.
Mortgage-backed securities have either fixed or adjustable interest rates. The
rate of return on mortgage-backed securities may be affected by prepayments on
principal on the underlying loans, which generally increase as interest rates
decline. As a result, when interest rates decline, holders of these securities
normally do not benefit from appreciation in market value to the same extent as
holders of other non-callable debt securities. In addition, the value of
mortgage-backed securities will fluctuate in response to market interest rates.
 
INVESTMENT LIMITATIONS
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may change their fundamental investment limitations without the affirmative vote
of the holders of a majority of the outstanding shares (as defined in the 1940
Act) of the particular Reorganizing Portfolio or Existing CoreFunds Portfolio.
The investment limitations of the Reorganizing Portfolios and the corresponding
Existing CoreFunds Portfolios are similar, but not identical.
    
 
   
     Each of the Reorganizing Portfolios (except the Conestoga Pennsylvania
Tax-Free Bond Fund) and each of the corresponding Existing CoreFunds Portfolios
(except the CoreFunds Pennsylvania Municipal Bond Fund) is a 'diversified'
investment portfolio and, therefore, has a fundamental policy limiting
investments in securities of any one issuer, other than securities issued by the
U.S. Government, its agencies and instrumentalities and repurchase agreements
collateralized by such securities, to 5% of the value of a fund's total assets,
except that up to 25% of the value of a fund's total assets may be invested
without regard to this 5% limitation. In addition, none of the Reorganizing
Portfolios (except the Conestoga Cash Management Fund, Tax-Free Fund, U.S.
Treasury Securities Fund and Pennsylvania Tax-Free Bond Fund) may acquire more
than 10% of the outstanding voting securities of any one issuer, except that the
Conestoga Equity Fund, Intermediate Income Fund, Balanced Fund and International
Equity Fund may invest up to 25% of their respective assets without regard to
such limitation. Of the CoreFunds, only the Value Equity Fund, Balanced Fund and
International Growth Fund have the same 10% voting securities limitation,
although CoreFunds Cash Reserve, Tax-Free Reserve, Treasury Reserve,
Intermediate Bond Fund and Pennsylvania Municipal Bond Fund have a fundamental
limitation prohibiting the purchase of any common stock or voting securities.
    
 
     With respect to at least 50% of the total assets of each of the Conestoga
Pennsylvania Tax-Free Bond Fund and CoreFunds Pennsylvania Municipal Bond Fund,
no more than 5% may be invested in securities of a single issuer, and no more
than 25% of each Fund's total assets may be invested in the securities of a
single issuer at the close of each quarter of each fiscal year. For purposes of
this limitation, governmental subdivisions, including states, territories,
possessions of the United States, or their political subdivisions, agencies,
authorities, instrumentalities, or similar entities, will be considered a
separate issuer if their assets and revenues are separate from those of the
government body creating it and the security is backed only by its own assets
and revenues. Industrial revenue bonds backed only by the assets and revenues of
a non-governmental issuer are considered to be issued solely by that user. If,
in the case of an industrial development bond or government-issued security, a
governmental or other entity guarantees the security, such guarantee would be
considered a separate security issued by the guarantor, as well as the other
issuer, subject to limited exclusions allowed by the 1940 Act.
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may borrow money directly except that each Fund may borrow money from banks and
enter into reverse repurchase
    
 
                                       42
<PAGE>
   
agreements for temporary purposes, and then in amounts not in excess of 10% of
the value of each Fund's total assets. A Reorganizing Portfolio (except the
Conestoga Tax-Free Fund) will not purchase securities while its borrowings,
including reverse repurchase agreements, exceed 5% of the total assets of the
Portfolio. Conestoga Tax-Free Fund and each Existing CoreFunds Portfolio will
not purchase securities while its borrowings, including reverse repurchase
agreements, are outstanding.
    
 
   
     The Reorganizing Portfolios and the Existing CoreFunds Portfolios may only
mortgage, pledge or hypothecate their assets to secure permitted indebtedness,
and then may only pledge assets having a market value not exceeding the lesser
of the dollar amounts borrowed or 10% of the value of total assets.
    
 
     The investment limitations described in the foregoing paragraphs regarding
diversification, borrowing and pledging of assets are fundamental with respect
to both Conestoga and CoreFunds.
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may make loans, except that: (i) Conestoga Equity Fund, Intermediate Income
Fund, Balanced Fund and International Equity Fund may lend portfolio securities;
and (ii) the Reorganizing Portfolios may purchase or hold certain debt
instruments and may enter into repurchase agreements; and (iii) each Existing
CoreFunds Portfolio may purchase or hold debt instruments and enter into
repurchase agreements. The foregoing limitations on securities lending are
fundamental limitations for both the Reorganizing Portfolios and the Existing
CoreFunds Portfolios.
    
 
   
     The Reorganizing Portfolios and the Existing CoreFunds Portfolios will not
invest 25% or more of the value of their respective total assets in any one
industry, provided that there is no limitation with respect to (i) obligations
issued or guaranteed by the U.S. Government, its agencies or instrumentalities;
(ii) tax-exempt securities issued by governments or political subdivisions of
governments; (iii) wholly-owned finance companies will be considered to be in
the industry of their parents if their activities are primarily related to
financing the activities of their partners; and (iv) utilities will be divided
according to their services. The foregoing investment limitations of each of the
Reorganizing Portfolios and the Existing CoreFunds Portfolios with respect to
industry concentration of investments is a fundamental investment limitation.
    
 
   
     Each of the Reorganizing Portfolios must limit its investments in illiquid
securities to 15% of its net assets, except that the Conestoga Cash Management
Fund, Tax-Free Fund and U.S. Treasury Securities are subject to a 10% limitation
and the Conestoga Equity Fund and Intermediate Income Fund will not invest in
repurchase agreements maturing in excess of seven days if such investment,
together with other investments of such Fund that are not readily marketable,
exceeds 10% of such Fund's total assets. By contrast, each of the Existing
CoreFunds Portfolios must limit its investments in illiquid securities to 10% of
its net assets (except for the CoreFunds Balanced and Pennsylvania Municipal
Bond Funds). With respect to the Reorganizing Portfolios, Rule 144A securities
will not be considered illiquid if the Funds' investment adviser determines that
an adequate trading market exists with respect to such securities. The foregoing
limitations on investments in illiquid securities are fundamental as to the
Existing CoreFunds Portfolios but are not fundamental as to the Reorganizing
Portfolios.
    
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may purchase or sell real estate, except that the Funds may purchase securities
of issuers which deal in real estate and may purchase securities which are
secured by interests in real estate.
    
 
   
     None of the Reorganizing Portfolios (except Conestoga Cash Management Fund,
Tax-Free Fund and U.S. Treasury Securities Fund) and the Existing CoreFunds
Portfolios may acquire any other investment company or investment company
security except in connection with a merger, consolidation, reorganization or
acquisition of assets or where otherwise permitted by the 1940 Act. The
Conestoga Cash Management Fund, Tax-Free Fund and U.S. Treasury Securities Fund
are not permitted to acquire investment company securities, except in connection
with a merger, consolidation, reorganization or acquisition of assets.
    
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may act as an
    
 
                                       43
<PAGE>
underwriter of securities within the meaning of the Securities Act of 1933
except to the extent that the purchase of obligations directly from the issuer
thereof, or the disposition of securities, in accordance with a Fund's
investment objective, policies and limitations may be deemed to be underwriting.
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may purchase securities of companies for the purpose of exercising control.
    
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may purchase securities on margin, make short sales of securities or maintain a
short position, except that each Reorganizing Portfolio may obtain such
short-term credits as may be necessary for the clearance of purchases and sales
of portfolio securities.
    
 
   
     None of the Existing CoreFunds Portfolios may invest in puts, calls,
straddles, spreads, or any combination thereof, except that (i) CoreFunds
International Growth Fund may enter into forward currency contracts, purchase
futures contracts and options thereon, and purchase, sell and write options on
securities (including puts and calls) to a limited extent; and (ii) CoreFunds
Pennsylvania Municipal Bond Fund may engage in put transactions.
    
 
   
     Neither the Reorganizing Portfolios nor the Existing CoreFunds Portfolios
may purchase or sell commodity contracts, or invest in oil, gas or mineral
exploration or development programs or leases.
    
 
   
     The following fundamental investment limitations of the Existing CoreFunds
Portfolios have no counterpart in the Reorganizing Portfolios:
    
 
     Each Existing CoreFunds Portfolio is prohibited from investing more than
10% of its total assets in the securities of any company not in operation
continuously for at least three years (including any predecessor company).
 
     Each Existing CoreFunds Portfolio is prohibited from purchasing or
retaining the securities of any issuer if officers and directors of CoreFunds,
or its advisor, owning beneficially more than one-half of 1% of the securities
of such issuer together own more than 5% of the securities of such issuer.
 
     The Existing CoreFunds Portfolios may not invest in securities with legal
or contractual restrictions.
 
     See 'Additional Investment Restrictions' in CoreFunds' Statement of
Additional Information which is incorporated by reference herein for additional
investment limitations of the Existing CoreFunds Portfolios.
 
     PURCHASE AND REDEMPTION INFORMATION, EXCHANGE PRIVILEGES, DISTRIBUTION AND
PRICING. The purchase, redemption, exchange privileges and distribution policies
of the Conestoga Portfolios and the CoreFunds Portfolios are discussed above
under 'Summary -- Overviews of the Conestoga Portfolios and CoreFunds
Portfolios' and below in Appendix III to this Combined Proxy
Statement/Prospectus.

            INTERIM INVESTMENT ADVISORY AND SUB-ADVISORY AGREEMENTS
 
   
     As stated above, because the Holding Company Merger will result in a change
in control of MIC, Conestoga's existing investment advisory and sub-advisory
agreements will, by their terms, automatically terminate on the date the Holding
Company Merger occurs. The Reorganization Agreement provides, that Conestoga
will enter into an interim investment advisory agreement with MIC (or its
successor), and that MIC will enter into an interim sub-advisory agreement with
Marvin and Palmer for the Conestoga International Equity Fund (together, the
'Interim Agreements'). The Interim Agreements will be in effect for the
Reorganizing Portfolios between the Holding Company Merger and the consummation
of the Reorganizing Portfolios Transaction. The interim advisory agreement will
be in effect for the Continuing Portfolios between the Holding Company Merger
and the consummation of the Continuing Portfolios Transaction. It is
contemplated that the firms that currently provide investment advisory and
sub-advisory services for the Conestoga Portfolios will continue to provide
services under the Interim Agreements.
    
 
     The investment advisory and sub-advisory fee rates stated in the Interim
Agreements will be the same, and the other provisions of the Interim Agreements
will be substantially the same, as those in the current investment and
sub-advisory agreements for the Conestoga Portfolios.
 
   
     Copies of the proposed Interim Agreements are attached as Appendix IV. In
the interim advisory agreement, MIC agrees, subject to the supervision of the
Conestoga Board of Trustees, to provide a continuous investment program for the
Conestoga Portfolios and to determine from time to time what securities and
other investments will be purchased, retained or sold in accordance with that
Portfolio's investment objectives, policies and restrictions. MIC's
responsibilities include, but are not limited to, placing purchase and sale
orders for portfolio transactions; maintaining books and records with respect to
a Portfolio's securities transactions; and furnishing periodic and special
reports to the Conestoga Board of Trustees as requested. The Interim Agreements
further provide that a Portfolio's investment adviser and sub-adviser will pay
all expenses incurred by it in connection with its advisory activities, other
than the cost of securities (including brokerage commissions, if any) purchased
for a Portfolio.
    
 
   
     With respect to the Conestoga International Equity Fund, some of the
investment adviser's responsibilities under the Interim Agreement will be
performed by the sub-adviser. In particular, Marvin and Palmer will, subject to
supervision by MIC (or its successor) and the Conestoga Board of Trustees,
manage the investment operations of the Conestoga International Equity Fund
during the Interim Period and determine the composition of the Fund, including
the purchase, retention and disposition of securities in accordance with the
Fund's investment objective, policies and restrictions. In addition, Marvin and
Palmer will prepare, subject to MIC's approval, lists of foreign countries for
investment by the Fund.
    
 
     Under the Interim Agreements, in placing orders with brokers and dealers,
the investment adviser and sub-adviser are to attempt to obtain prompt execution
of orders at the most favorable price. Consistent with this obligation, when the
execution and price offered by two or more brokers or dealers are comparable,
the investment adviser or sub-adviser may, in its discretion, purchase and sell
portfolio securities to and from brokers and dealers that provide research
advice and other services. These brokerage and research services might consist
of reports and statistics on specific companies of industries, general summaries
of groups of stocks or bonds and their comparative earnings and yields, or broad
overviews of the securities markets and the economy.
 
     Supplementary research information so received is in addition to, and not
in lieu of, services required to be performed by the investment adviser or
sub-adviser, and does not reduce the advisory fees payable by the Conestoga
Portfolios. It is possible that certain of the supplementary research or other
services received will primarily benefit one or more other investment companies
or other accounts for which the investment adviser or sub-adviser exercises
investment discretion. Conversely, the Conestoga Portfolios may be the primary
beneficiary of the research or services received as a result of portfolio
transactions effected for such other account or investment company.
 
                                       45
<PAGE>
   
     Investment decisions for the Conestoga Portfolios and for other investment
accounts managed by the investment adviser and sub-adviser under the Interim
Agreements will be made independently of each other in light of differing
conditions. However, the same investment decision may be made for two or more of
such accounts. In such cases, simultaneous transactions are inevitable.
Purchases or sales are then allocated in a manner believed by the investment
adviser or sub-adviser to be equitable to each such account. While in some cases
this practice could have a detrimental effect on the price or value of the
security as far as a Conestoga Portfolio is concerned, in other cases it may be
beneficial to the portfolio. To the extent permitted by law, the investment
adviser or sub-adviser may aggregate the securities to be sold or purchased for
the Conestoga Portfolios with those to be sold or purchased for other investment
companies or accounts in executing transactions. Portfolio securities will not
be purchased from or sold to the investment adviser, sub-adviser, or any
affiliated person, except as permitted under the 1940 Act.
    
 
     If in any fiscal year the aggregate expenses of any Conestoga Portfolio
exceeds the expense limitation of any state having jurisdiction over Conestoga,
the Interim Agreements provide that the Portfolio's investment adviser will
reimburse the Portfolio for a portion of such excess expenses equal to such
excess times the ratio of the fees otherwise payable by the Portfolio to the
investment adviser to the aggregate fees otherwise payable by the Portfolio to
the investment adviser and to the Portfolio's administrator under its
administration agreement. The obligation of the investment adviser to reimburse
a Portfolio is limited in any fiscal year to the amount of its fee for such
fiscal year, provided that an investment adviser will reimburse a Portfolio for
such proportion of such excess expenses regardless of the amount of fees paid to
it during such fiscal year to the extent that the securities regulations of any
state having jurisdiction over Conestoga so require. As of the date hereof, the
most restrictive expense limitation applicable to a Conestoga Portfolio limits
its aggregate annual expenses (as defined by applicable regulations) to 2 1/2%
of the first $30 million of its average net assets, 2% of the next $70 million
of its average net assets, and 1 1/2% of its remaining net assets.
 
     The investment adviser or sub-adviser will not be liable for any error of
judgment or mistake of law or for any loss suffered by a Conestoga Portfolio in
connection with the performance of its agreements, except a loss arising from a
breach of fiduciary duty with respect to the receipt of compensation for
services or a loss resulting from wilful misfeasance, bad faith or gross
negligence on the part of the investment adviser or sub-adviser in the
performance of its duties or from reckless disregard by it of its obligations
and duties under the agreements.
 
   
     Should the Reorganization not occur, the Interim Agreements may be renewed
for successive annual periods with respect to a Conestoga Portfolio if
specifically approved at least annually (a) by the vote of a majority of those
members of the Conestoga Board of Trustees who are not parties to the agreements
or interested persons of any party to the agreements, cast in person at a
meeting called for the purpose of voting on such approval, and (b) by the vote
of a majority of the Conestoga Board of Trustees or by the vote of a majority of
all votes attributable to the outstanding shares of the Portfolio.
    
 
     The Interim Agreements will terminate upon their assignment (as defined in
the 1940 Act). In addition, the Interim Agreements may be terminated with
respect to any Conestoga Portfolio by the Conestoga Board of Trustees, by vote
of a majority of the outstanding shares of that Portfolio, by the investment
adviser or, in the case of an Interim Sub-Advisory Agreement, by either the
investment adviser or sub-adviser upon notice as stated in the particular
agreement.
 
   
     The table at page 3 shows (i) the current contractual fee rates for the
Conestoga Portfolios, which will be the same throughout the Interim Period until
the time of the transactions, and (ii) the advisory/sub-advisory fees actually
paid by the Conestoga Portfolios for their last fiscal year net of waivers. All
fee rates are annualized, and are computed daily and payable monthly based on a
Portfolio's average daily net assets.

                     INFORMATION RELATING TO VOTING MATTERS
 
     GENERAL INFORMATION.  This Combined Proxy Statement/Prospectus is being
furnished in connection with the solicitation of proxies by Conestoga's Board of
Trustees in connection with the Meeting. It is expected that the solicitation of
proxies will be primarily by mail. Officers and service contractors of Conestoga
may also solicit proxies by telephone, telegraph, facsimile or personal
interview. Any shareholder giving a proxy may revoke it at any time before it is
exercised by submitting to Conestoga a written notice of revocation or a
subsequently executed proxy or by attending the Meeting and voting in person.
 
   
     Only shareholders of record at the close of business on January 26, 1996
will be entitled to vote at the Meeting. On that date there were outstanding and
entitled to be voted 234,883,522.79 shares of the Conestoga Cash Management
Fund, 47,526,615.37 shares of the Conestoga Tax-Free Fund, 436,965,068.60 shares
of the Conestoga U.S. Treasury Securities Fund, 21,620,456.5884 shares of the
Conestoga Equity Fund, 5,441,676.9690 shares of the Conestoga Special Equity
Fund, 18,131,183.9921 shares of the Conestoga Bond Fund, 11,856,351.8320 shares
of the Conestoga Intermediate Income Fund, 636,811.79 shares of the Conestoga
Pennsylvania Tax-Free Bond Fund, 3,626,636.716 shares of the Conestoga Balanced
Fund, 3,431,978.3660 shares of the Conestoga Short-Term Income Fund and
1,377,454.999 shares of the Conestoga International Equity Fund. Each share or
fraction thereof is entitled to one vote or fraction thereof, and all shares
will vote separately by Fund.
    
 
   
     Conestoga and CoreFunds have been advised by MIC that the shares of each
Conestoga Portfolio over which Meridian Bancorp, Inc. or its affiliates have
voting power will, except as to accounts established for Meridian's employee
benefit plan, be voted in accordance with instructions received from beneficial
owners or fiduciaries of such accounts who are not related to Meridian Bancorp,
Inc. or its affiliates. As to Meridian's own employee benefit plan, and as to
accounts for which no instructions are received from beneficial owners or
fiduciaries, Meridian will cast such votes in accordance with the recommendation
of a fiduciary that is independent of Meridian.
    
 
     If the accompanying proxy is executed and returned in time for the Meeting,
the shares covered thereby will be voted in accordance with the proxy on all
matters that may properly come before the Meeting or any adjournment thereof.
For information on adjournment of the meeting, see 'Quorum' below.
 
   
     SHAREHOLDER AND BOARD APPROVALS.  The Reorganization Agreement (and the
transactions contemplated thereby including the implementation of the interim
investment advisory and sub-advisory agreements), is being submitted for
approval at the Meeting by the holders of a majority of the outstanding shares
of the Conestoga Cash Management Fund, Tax-Free Fund, U.S. Treasury Securities
Fund, Equity Fund, Special Equity Fund, Bond Fund, Intermediate Income Fund,
Pennsylvania Tax-Free Bond Fund, Balanced Fund, Short-Term Income Fund and
International Equity Fund in accordance with the provisions of Conestoga's
Declaration of Trust and the requirements of the 1940 Act. The term 'majority of
the outstanding shares' of a Conestoga Portfolio as used herein means the lesser
of (a) 67% of the shares of the particular Conestoga Portfolio present at the
Meeting if the holders of more than 50% of the outstanding shares of the
Conestoga Portfolio are present in person or by proxy, or (b) more than 50% of
the outstanding shares of such Conestoga Portfolio.
    
 
     In tallying shareholder votes, abstentions and broker non-votes (i.e.,
proxies sent in by brokers and other nominees that cannot be voted on a proposal
because instructions have not been received from the beneficial owners) will be
counted for purposes of determining whether or not a quorum is present for
purposes of convening the meeting. On the Reorganization proposal abstentions
and broker non-votes will be considered to be a vote against the Reorganization
proposal.
 
   
     The approval by the shareholders of the corresponding Existing CoreFunds
Portfolios of the Reorganization is not being solicited because their approval
or consent is not necessary for the Reorganization to be consummated.

     APPRAISAL RIGHTS.  Shareholders are not entitled to any rights of share
appraisal under Conestoga's Declaration of Trust or under the laws of the
Commonwealth of Massachusetts in
 
                                       57
<PAGE>
connection with the Reorganization. Shareholders have, however, the right to
redeem from Conestoga their Conestoga Portfolio shares at net asset value until
the Effective Time of the Reorganization, and thereafter shareholders may redeem
from CoreFunds the CoreFunds shares acquired by them in the Reorganization at
net asset value.
 
     QUORUM.  In the event that a quorum is not present at the Meeting, or in
the event that a quorum is present at the Meeting but sufficient votes to
approve the Reorganization Agreement and the transactions contemplated thereby
are not received, the persons named as proxies may propose one or more
adjournments of the Meeting to permit further solicitation of proxies. Any such
adjournment will require the affirmative vote of a majority of those shares
affected by the adjournment that are represented at the Meeting in person or by
proxy. If a quorum is present, the persons named as proxies will vote those
proxies which they are entitled to vote FOR the Reorganization Agreement, in
favor of such adjournments, and will vote those proxies required to be voted
AGAINST such proposals against any adjournment. A shareholder vote may be taken
with respect to one or more Conestoga Portfolios prior to any such adjournment
if sufficient votes have been received for approval with respect to any such
Conestoga Portfolio. A quorum is constituted with respect to a Conestoga
Portfolio by the presence in person or by proxy of the holders of more than 50%
of the outstanding shares of the Fund entitled to vote at the Meeting. Conestoga
proxies properly executed and marked with a negative vote or an abstention will
be considered to be present at the Meeting for the purposes of determining the
existence of a quorum for the transaction of business.
 
     ANNUAL MEETINGS.  CoreFunds does not presently intend to hold annual
meetings of shareholders for the election of directors and other business unless
and until such time as less than a majority of the directors holding office have
been elected by the shareholders, at which time the directors then in office
will call a shareholders' meeting for the election of directors. Shareholders
have the right to call a meeting of shareholders to consider the removal of one
or more directors or for other matters and such meetings will be called when
requested in writing by the holders of record of 10% or more of CoreFunds'
outstanding shares of common stock. To the extent required by law, CoreFunds
will assist in shareholder communications on such matters.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
   
     AGREEMENT AND PLAN OF REORGANIZATION made as of February 8, 1996 between
COREFUNDS, INC., a Maryland corporation ('CoreFunds'), and CONESTOGA FAMILY of
FUNDS, a Massachusetts business trust ('Conestoga').
    
 
     WHEREAS, the parties desire that substantially all of the known assets and
liabilities of Conestoga's portfolios be transferred to, and be acquired and
assumed by, certain CoreFunds portfolios in exchange for Individual Shares or
Institutional Shares of the CoreFunds portfolios which shall thereafter be
distributed by Conestoga to the holders of Retail Shares or Institutional Shares
of its portfolios, all as described in this Agreement (the 'Reorganization');
 
     WHEREAS, the parties intend that the CoreFunds Special Equity Fund, Bond
Fund and Short-Term Income Fund portfolios will have nominal assets and
liabilities before the Reorganization and will continue the investment
operations of the Conestoga Special Equity Fund, Bond Fund and Short-Term Income
Fund (the 'Continuing Funds'), respectively, after the Reorganization;
 
     WHEREAS, the Reorganization with respect to Conestoga's Cash Management
Fund, Tax-Free Fund, U.S. Treasury Securities Fund, Equity Fund, Intermediate
Income Fund, Pennsylvania Tax-Free Bond Fund, Balanced Fund and International
Equity Fund (the 'Reorganizing Funds') shall occur on a date that is prior to
the Reorganization with respect to the Continuing Funds;
 
     WHEREAS, the parties intend that the transfers of assets, assumptions of
liabilities, and distributions of Individual Shares or Institutional Shares, as
the case may be, be treated as tax-free reorganizations under Section
368(a)(1)(C), 368(a)(1)(D), or 368(a)(1)(F) of the Internal Revenue Code of
1986, as amended (the 'Code'); and
 
     WHEREAS, the parties intend that in connection with the Reorganization each
of the Conestoga portfolios shall be terminated and Conestoga shall be
terminated under state law and deregistered as described in this Agreement.
 
     NOW, THEREFORE, in consideration of the mutual covenants and agreements
hereinafter set forth and subject to the terms and conditions hereof, and
intending to be legally bound hereby, CoreFunds and Conestoga agree as follows:
 
     I. Transfer of Assets of Conestoga Portfolios.
 
     1.01 (a) At the Effective Time of the Reorganization (as defined in Article
              VIII) with respect to each of the Conestoga portfolios (each, an
              'Acquired Fund'), all property of every description, and all
              interests, rights, privileges and powers of each Acquired Fund
              other than cash in an amount necessary to pay any unpaid dividends
              and distributions as provided in Article IV(g) (such assets, the
              'Acquired Fund Assets') shall be transferred and conveyed by such
              Acquired Fund to CoreFunds on behalf of one of its portfolios as
              set forth in Section 1.02 (each, an 'Acquiring Fund'), and shall
              be accepted by CoreFunds on behalf of such Acquiring Fund, and
              CoreFunds, on behalf of such Acquiring Fund, shall assume all
              known liabilities whether accrued, absolute, contingent or
              otherwise, of such Acquired Fund reflected in the calculation of
              such Acquired Fund's net asset value (the 'Acquired Fund
              Liabilities'), so that at and after the Effective Time of the
              Reorganization with respect to such Acquired Fund: (i) all assets
              of such Acquired Fund shall become and be the assets of its
              Acquiring Fund; and (ii) all known liabilities of such Acquired
              Fund reflected as such in the calculation of the Acquired Fund's
              net asset value shall attach to its Acquiring Fund as aforesaid
              and may thenceforth be enforced against such Acquiring Fund to the
              extent as if the same had been incurred by it. Without limiting
              the generality of the foregoing, the Acquired Fund Assets shall
              include all property and assets of any nature whatsoever,
              including, without limitation, all cash, cash equivalents,
              securities, claims and receivables (including dividend and
              interest receivables) owned by an Acquired Fund, and (subject to
              Section 1.01(b)) any deferred or prepaid expenses shown as an
              asset on an Acquired Fund's books, at the
 
                                      A-1
<PAGE>
              Effective Time of the Reorganization of such Acquired Fund, and
              all good will, all other intangible property and all books and
              records belonging to an Acquired Fund. Recourse by any person for
              the Acquired Fund Liabilities assumed by an Acquiring Fund shall,
              at and after the Effective Time of the Reorganization of such
              Acquired Fund, be limited to such Acquiring Fund.
 
          (b) Notwithstanding Section 1.01(a), unamortized organizational
              expenses of the Reorganizing Funds shall not be transferred or
              assumed hereunder. The parties have been advised that such
              expenses will be paid to such Reorganizing Funds by one or more
              third parties and will be eliminated from the balance sheets of
              such Reorganizing Funds prior to the applicable Effective Time of
              the Reorganization of the Reorganizing Funds.
 
     1.02 The assets of each Acquired Fund shall be acquired by the Acquiring
Fund identified below opposite its name, and the holders of each class of shares
of such Acquired Fund shall receive the class of shares of common stock of the
Acquiring Fund identified below opposite the name of such class:

The Board of Directors of CoreFunds has adopted resolutions authorizing the
change of names of the Intermediate Bond Fund to the Short Intermediate Bond
Fund and of the Value Equity Fund to the Equity Fund and the change of
designations of the classes of each Acquiring Fund (i) from Individual-Class A
to Class A for each Acquiring Fund except the Cash Reserve Fund, Tax-Free
Reserve Fund and Treasury Reserve Fund, which will be designated Class C, and
(ii) from Institutional-Class B to Class Y for each Acquiring Fund. These
changes will be effective by the Effective Time of the Reorganization with
respect to each Acquired Fund.
 
     1.03 In exchange for the transfer of the Acquired Fund Assets and the
assumption of the Acquired Fund Liabilities, CoreFunds shall simultaneously
issue at the applicable Effective Time of the Reorganization to each Acquired
Fund a number of full and fractional shares to the third decimal place, of the
Acquiring Fund specified in Section 1.02 and of the class or classes identified
in Section 1.02, all determined and adjusted as provided in this Agreement. The
number of each class of shares of the Acquiring Funds so issued will have an
aggregate net asset value equal to the value of the Acquired Fund Assets that
are represented by the class of shares of the Acquired Fund, the holders of
which shall receive such class of shares of the Acquiring Fund, as specified in
Section 1.02, all determined and adjusted as provided in this Agreement.
 
     1.04 The net asset value of each class of shares of the Acquiring Funds and
the net asset value of each class of shares of the Acquired Funds shall be
determined as of the applicable Valuation Time with respect to each Acquired
Fund specified in Article III.
 
     1.05 The net asset value of each class of shares of each Acquiring Fund
shall be computed in the manner set forth in such Acquiring Fund's then current
prospectuses under the Securities Act of 1933, as amended (the '1933 Act'). The
net value of the Acquired Fund Assets to be transferred by the Conestoga
portfolios shall be computed by Conestoga and shall be subject to adjustment by
the amount, if any, agreed to by CoreFunds and Conestoga. In determining the
value of the securities transferred by the Acquired Funds to the Acquiring
Funds, each security shall be priced in accordance with the policies and
procedures of CoreFunds described in its then current prospectuses and
statements of additional information and adopted by CoreFunds' Board of
Directors, which are and shall be consistent with the policies now in effect for
Conestoga. For such purposes, price quotations and the security characteristics
relating to establishing such quotations shall be determined by CoreFunds,
provided that such determination shall be subject to the approval of Conestoga.
 
                                      A-3
<PAGE>
     The value of the Acquired Fund Assets of the Conestoga Cash Management
Fund, Tax-Free Fund and U.S. Treasury Securities Fund (each, a 'Conestoga Money
Market Fund') and the value of the shares of the corresponding Acquiring Funds
for purposes of sales and redemptions shall be based on the amortized cost
valuation procedures that have been adopted by the Board of Trustees of
Conestoga and the Board of Directors of CoreFunds, respectively. Any provision
in this Agreement to the contrary notwithstanding, if the difference between the
per share net asset values of a Conestoga Money Market Fund and its
corresponding Acquiring Fund equals or exceeds $.0025 at the applicable
Valuation Time, as computed by using such market values in accordance with the
policies and procedures established by CoreFunds (or as otherwise mutually
determined by the Board of Trustees of Conestoga and the Board of Directors of
CoreFunds), either the Board of Trustees of Conestoga or the Board of Directors
of CoreFunds shall have the right to postpone the applicable Valuation Time and
the applicable Effective Time of the Reorganization with respect to such
Conestoga Money Market Fund until such time as the per share difference is less
than $.0025.
 
   
     II. Liquidating Distributions and Termination of Conestoga. Immediately
after the Effective Time of the Reorganization with respect to each Acquired
Fund, such Acquired Fund shall distribute in complete liquidation pro rata to
the record holders of each class of its shares at the applicable Effective Time
of the Reorganization the shares of the class of the Acquiring Fund identified
in Section 1.02 to be received by the record holders of such class of such
Acquired Fund. In addition, each shareholder of record of an Acquired Fund shall
have the right to receive any unpaid dividends or other distributions which were
declared before the applicable Effective Time of the Reorganization with respect
to the shares of an Acquired Fund that are held by the shareholder at the
applicable Effective Time of the Reorganization. In accordance with instructions
it receives from Conestoga, CoreFunds shall record on its books the ownership of
each class of shares of each Acquiring Fund by the record holders of the class
of shares of the Acquired Fund identified in Section 1.02. All of the issued and
outstanding shares of each class of each Acquired Fund shall be redeemed and
canceled on the books of Conestoga at the Effective Time of the Reorganization
of such Acquired Fund and shall thereafter represent only the right to receive
the class of shares of the Acquiring Fund identified in Section 1.02, and the
Acquired Fund's transfer books shall be closed permanently. As soon as
practicable after the Effective Time of the Reorganization with respect to the
Continuing Funds, Conestoga shall make all filings and take all other steps as
shall be necessary and proper to effect its complete dissolution, and shall file
an application pursuant to Section 8(f) of the 1940 Act for an order declaring
that it has ceased to be an investment company and any and all documents that
may be necessary to terminate its existence under state law. After the Effective
Time of the Reorganization with respect to the Continuing Funds, Conestoga shall
not conduct any business except in connection with its liquidation, dissolution,
and deregistration.
    
 
     III. Valuation Times. Subject to Section 1.05 hereof, (a) the Valuation
Time for the Reorganization with respect to the Reorganizing Funds shall be 4:00
P.M., Eastern Time, on such date as may be agreed in writing by the duly
authorized officers of both parties hereto, which date shall not be later than
the thirty-first calendar day following the consummation of the merger between
CoreStates Financial Corp and Meridian Bancorp, Inc. described in an Agreement
and Plan of Merger dated October 10, 1995 (the 'Bank Holding Company Merger'),
and (b) the Valuation Time for the Reorganization with respect to the Continuing
Funds shall be 4:00 p.m., Eastern Time, on such date as may be agreed in writing
by the duly authorized officers of both parties hereto, which date shall be not
less than seven calendar days following the Valuation Time for the
Reorganization with respect to the Reorganizing Funds.
 
     IV. Certain Representations, Warranties and Agreements of Conestoga.
Conestoga, on behalf of itself and each Acquired Fund, represents and warrants
to, and agrees with, CoreFunds as follows:
 
(a) It is a Massachusetts business trust duly created pursuant to its Agreement
    and Declaration of Trust for the purpose of acting as a management
    investment company under the 1940 Act and is validly existing under the laws
    of, and duly authorized to transact business in, the Commonwealth of
    Massachusetts. It is registered with the
 
                                      A-4
<PAGE>
    Securities and Exchange Commission (the 'SEC') as an open-end management
    investment company under the 1940 Act and such registration is in full force
    and effect.
 
(b) It has power to own all of its properties and assets and, subject to the
    approvals of shareholders referred to herein, to carry out and consummate
    the transactions contemplated hereby, and has all necessary federal, state
    and local authorizations to carry on its business as now being conducted and
    to consummate the transactions contemplated by this Agreement.
 
(c) This Agreement has been duly authorized, executed and delivered by
    Conestoga, and represents Conestoga's valid and binding contract,
    enforceable in accordance with its terms, subject as to enforcement to
    bankruptcy, insolvency, reorganization, arrangement, moratorium, and other
    similar laws of general applicability relating to or affecting creditors'
    rights and to general principles of equity. The execution and delivery of
    this Agreement does not and will not, and the consummation of the
    transactions contemplated by this Agreement will not, violate Conestoga's
    Agreement and Declaration of Trust or Code of Regulations or any agreement
    or arrangement to which it is a party or by which it is bound.
 
(d) Each Acquired Fund has elected to qualify and has qualified as a regulated
    investment company under Part I of Subchapter M of the Code, as of and since
    its first taxable year; has been a regulated investment company under such
    Part of the Code at all times since the end of its first taxable year when
    it so qualified; and qualifies and shall continue to qualify as a regulated
    investment company until the Effective Time of the Reorganization with
    respect to such Acquired Fund.
 
(e) All federal, state, local and foreign income, profits, franchise, sales,
    withholding, customs, transfer and other taxes, including interest,
    additions to tax and penalties (collectively, 'Taxes') relating to the
    Acquired Fund Assets due or properly shown to be due on any return filed by
    any Acquired Fund with respect to taxable periods ending on or prior to, and
    the portion of any interim period up to, the date hereof have been fully and
    timely paid or provided for; and there are no levies, liens, or other
    encumbrances relating to Taxes existing, threatened or pending with respect
    to the Acquired Fund Assets.
 
(f) The financial statements of Conestoga's U.S. Treasury Securities Fund, Cash
          Management Fund, Tax-Free Fund, Intermediate Income Fund, Bond Fund,
    Equity Fund, Special Equity Fund, and Pennsylvania Tax-Free Bond Fund for
    the fiscal year ended October 31, 1995, and the financial statements of
    Conestoga's Balanced Fund, Short-Term Income Fund, and International Equity
    Fund for their respective fiscal periods ended October 31, 1995, examined by
    Coopers & Lybrand L.L.P., copies of which have been previously furnished to
    CoreFunds, present fairly the financial position of each Acquired Fund as of
    October 31, 1995 and the results of its operations for the year or period
    then ending, in conformity with generally accepted accounting principles.
 
(g) Prior to the Valuation Time applicable to the Reorganizing Funds, each of
    the Reorganizing Funds shall have declared a dividend or dividends, with a
    record date and ex-dividend date prior to such Valuation Time, which,
    together with all previous dividends, shall have the effect of distributing
    to its shareholders all of its net investment company income, if any, for
    the taxable periods or years ended on or before October 31, 1995 and for the
    period from said date to and including the Effective Time of the
    Reorganization applicable to the Reorganizing Funds (computed without regard
    to any deduction for dividends paid), and all of its net capital gain, if
    any, realized in taxable periods or years ended on or before October 31,
    1995 and in the period from said date to and including the Effective Time of
    the Reorganization applicable to the Reorganizing Funds.
 
                                      A-5
<PAGE>
(h) At both the Valuation Time and the Effective Time of the Reorganization with
    respect to each Acquired Fund, there shall be no known liabilities of such
    Acquired Fund, whether accrued, absolute, contingent or otherwise, not
    reflected in the net asset values per share of its outstanding classes of
    shares.
 
(i) There are no legal, administrative or other proceedings pending or, to
    Conestoga's knowledge threatened, against Conestoga or an Acquired Fund
    which could result in liability on the part of Conestoga or an Acquired
    Fund.
 
(j) Subject to the approvals of shareholders referred to herein, at both the
    Valuation Time and the Effective Time of the Reorganization with respect to
    each Acquired Fund, it shall have full right, power and authority to sell,
    assign, transfer and deliver the Acquired Fund Assets of such Acquired Fund
    and, upon delivery and payment for the Acquired Fund Assets as contemplated
    herein, an Acquiring Fund shall acquire good and marketable title thereto,
    free and clear of all liens and encumbrances, and subject to no restrictions
    on the ownership or transfer thereof (except as imposed by federal or state
    securities laws).
 
(k) No consent, approval, authorization or order of any court or governmental
    authority is required for the consummation by Conestoga of the transactions
    contemplated by this Agreement, except such as may be required under the
    1933 Act, the Securities Exchange Act of 1934, as amended ('1934 Act'), the
    1940 Act, the rules and regulations under those Acts, and state securities
    laws.
 
(l) Insofar as the following relate to Conestoga, the registration statement
    filed by CoreFunds on Form N-14 relating to the shares of certain Acquiring
    Funds that will be registered with the SEC pursuant to this Agreement,
    which, without limitation, shall include a proxy statement of Conestoga and
    the prospectuses of CoreFunds with respect to the transactions contemplated
    by this Agreement, and any supplement or amendment thereto or to the
    documents contained or incorporated therein by reference (the 'N-14
    Registration Statement'), on the effective date of the N-14 Registration
    Statement, at the time of any shareholders' meeting referred to herein and
    at each Effective Time of the Reorganization: (i) shall comply in all
    material respects with the provisions of the 1933 Act, the 1934 Act and the

    insolvency, reorganization, arrangement, moratorium, and other similar laws

    the results of its operations for the year and period ended as of such
    dates, in conformity with generally accepted accounting principles.
 
(f) At both the Valuation Time and the Effective Time of the Reorganization with
    respect to each Acquiring Fund, there shall be no known liabilities of such

    authority is required for the consummation by CoreFunds of the transactions

    to an Acquired Fund for the account of record holders of shares of an
    Acquired Fund, pursuant to the terms hereof, shall have been duly authorized
    as of the Effective Time of the Reorganization application to such Acquiring
    Fund and, when so issued and delivered, shall be registered under the 1933
    Act and under applicable state securities laws, duly and validly issued,
    fully paid and non-assessable, and no shareholder of CoreFunds shall have
    any preemptive right of subscription or purchase in respect thereto.

policy of such Acquired Funds that might be deemed to prevent them from taking

    purposes (i) the transfers of all of the Acquired Fund Assets hereunder, and
    the assumption by its Acquiring Fund of Acquired Fund Liabilities, in
    exchange for shares of each class of such Acquiring Fund, and the
    distribution of said shares to the shareholders of such Acquired Fund, as
    provided in this Agreement, will each constitute a reorganization within the
    meaning of Section 368(a)(1)(C), 368(a)(1)(D) or 368(a)(1)(F) of the Code
    and with respect to each reorganization, the Acquired Fund and the Acquiring

    to the transactions; (vi) in accordance with Section 362(b) of the Code, the
    basis of the Acquired Fund Assets to any Acquiring Fund will be the same as

    Acquired Fund immediately prior to the exchange; (vii) in accordance with
    Section 1223 of the Code, a shareholder's holding period for Acquiring Fund
    shares will be determined by including the period for which the shareholder
    held the shares of an Acquired Fund exchanged therefor, provided that the
    shareholder held such shares of an Acquired Fund as a capital asset; and
    (viii) in accordance with Section 1223 of the Code, the holding period of an
    Acquiring Fund with respect to the Acquired Fund Assets will include the

         EXISTING COREFUNDS PORTFOLIOS MANAGEMENT DISCUSSION & ANALYSIS
    
 
     The CoreFund Value Equity Fund, Series A, returned 17.29% for the 12-month
period ending June 30, 1995. While in absolute terms this was an acceptable
return, the S&P 500 returned 26.0% in the same timeframe.
 
     For Series B shares from which a sales charge has been deducted, the return
for the period was 11.7%; for those without a sales load it was 17.0%.
 
     The most significant economic event during the period was the series of
moves made by the Federal Reserve Board to tighten interest rates. With the
Fund's exposure to industrial issues that are more economically sensitive, the
Fed's actions negatively affected performance. Investors in the broad market
sold industrial issues and purchased so-called defensive issues in groups such
as pharmaceuticals, tobacco, and food and beverage, where earnings are less
dependent on economic activity. The Fund's exposure in these sectors is
underweighted compared to the broader market.
 
     As the new fiscal year begins, we are optimistic that the industrial sector
will come back into favor. Even as the economy has slowed, industrial issues
have continued to display positive fundamentals and solid earnings. Productivity
enhancements, careful control of inventories and costs, and exposure to
still-healthy global economies have helped these companies maintain steady
results during boom/bust cycles. The interest rate decrease instituted by the
Fed at the beginning of the new fiscal year, combined with excellent company
fundamentals, should bring investors back to the sector.
 
     The Fund has also benefitted from investment in financial issues such as
security brokerages, investment management firms, and mutual fund companies.
Specific investments have included Merrill Lynch, Charles Schwab, Salomon
Brothers, and Franklin Resources. As the 'graying of America' continues and more
government policies are instituted that reward investment, the long-term outlook
for financial issues remains strong.
 
     Overall, we continue to maintain a constructive outlook for the value
equity market. The breadth of issues participating in the rally indicates that
excesses can be worked off individually, without damaging the fabric of an
overall market that is healthy and improving.

Series B (synthetic) prior to that date is based on the performance of
Institutional Series A shares adjusted to reflect the maximum sales charge of
4.5% for the Series B shares. Series A shares of the Value Equity Portfolio
commenced operations on February 6, 1990.


 
                           INTERNATIONAL GROWTH FUND
 
     The International Growth Fund, Series A shares, returned (0.21)% for the
year ended June 30, 1995. This compared favorably with the 0.1% increase of the
MSCI EAFE Index during the same period.
 
     For Series B shares from which a sales charge has been deducted, the return
for the period was (4.95)%; for those without a load it was (0.48)%.
 
     Despite continued growth in most of the world's major economies,
international stock markets have been affected by considerable currency
volatility. In December, the Mexican crisis caused investors to repatriate funds
that had been invested in many of the world's smaller or 'emerging' markets.
 
     The International Growth Fund's largest single area of investment is Japan
(34%). This was the worst-performing major market in the period, falling by 28%.
A currency gain softened the damage for the U.S. investor, however. The Kobe
earthquake in February 1995 disrupted Japan's infrastructure and manufacturing
industries, and had a considerable, albeit short-term, impact on economic
activity.
 
     The rise of the Yen is of greater long-term significance. This has made
Japan's exports less competitive, and encouraged a flood of imports. In turn,
this has put pressure on economic growth and corporate margins, and kept the
domestic investor away from the stock market. Although the Japanese financial
sector is hardly in the best of health, the manufacturing sector has suffered
the worst.
 
     One bright spot has been the technology sector, in which the Fund has a
large position.
 
                                      B-2
<PAGE>
     This allowed the Fund to outperform the Tokyo Stock Exchange Index over the
12-month period.
 
   
     Through most of the year, the Fund was partially hedged against weakness in
the Yen, through a forward sale of Yen for U.S. dollars. This hedge expired in
February, shortly before another sharp rise in the Yen (to Y80/US$). The hedge
was subsequently reinstated; currently, 28% of the Fund's Japanese assets are
protected.
    
 
     Southeast Asia, which currently accounts for 17% of the Fund's portfolio,
was an unrewarding region for most of the year. In Hong Kong, Singapore and
Malaysia, where local currencies are linked to the U.S. dollar, stock markets
suffered at a time when U.S. interest rates were rising. However, there was a
strong recovery toward the end of the period, spurred by the strengthening U.S.
bond market. In Hong Kong (at 6% the Fund's largest position in the region), the
Index rose by 5%, despite concerns about Chinese politics and weakness in local
real estate prices.
 
     In Western Europe, which currently accounts for 40% of the Fund's holdings,
the past 12 months was a period of economic recovery. The improvement was
largely led by exports, as high rates of unemployment in the region discouraged
local consumption. However, the strength of the Deutschemark in the first half
of 1995 created problems for export industries in Germany, where there is now
considerable pressure on corporate earnings.
 
     International confidence in Latin America was dealt a heavy blow at the end
of 1994 by a series of political scandals and a mishandling of the Mexican
economy. This led to a 40% devaluation of the Peso and a collapse in the Mexican
stock market, as international capital, on which the Mexican economy relies so
heavily, was quickly repatriated. Stock markets in Brazil and Argentina suffered
a similar fate (somewhat unfairly, as the commitment to economic discipline
appears much stronger in those countries than in Mexico). Despite some recovery
toward the end of the period, indices in both countries remain well below their
December levels.
 
     The Fund's position in the region had been reduced prior to the Mexican
crisis, and further sales were made thereafter. The Fund now has only 5% of its
portfolio in Latin America, with no holdings in Mexico.

                                 BALANCED FUND
 
     Performance of Series A shares of the Balanced Fund improved significantly
during the year ended June 30, 1995, generating a 16.21% gain for the period.
This compared with a 26.01% return for the Standard & Poor's 500 Index, and a
10.37% return for the Lehman Brothers Intermediate Government/Corporate Bond
Index.
 
     For Series B shares from which a sales charge has been deducted, the return
for the period was 10.58%; for those without a load it was 15.84%. The Balanced
Fund grew in asset size through June 30 to $63,436,000.
 
     The Balanced Fund's equity holdings modestly underperformed a very strong
S&P Index during the period, rising 24.0%. Returns from the Fund's holdings in
the technology sector and from pharmaceutical issues matched or outperformed
those sectors in the broader market. Additionally, strong positions in the cable
television, entertainment and gaming industries more than offset weakness in the
Fund's underweighted holdings (relative to the broader market) in
interest-sensitive sectors.
 
     The Fund's fixed-income holdings underperformed the fixed-income benchmark
during the 12-month period (9.2% vs. the Bond Index's 10.37%). The Fund's bond
holdings were overweighted in the two-years-or-less portion of the yield curve;
this market segment generated smaller returns than longer-dated securities. Our
defensive posture, which served the Fund well during the first six months of the
period, made it difficult to fully exploit the rapid and sharp rally in bond
prices during the final three months of the period.
 
                                      B-4
<PAGE>
     Cash levels in the Fund are fairly low, reflecting a fully invested
position in stocks and bonds. We anticipate continued volatility in the capital
markets, with an upward bias, during the second half of 1995. During periods of
weakness, we plan to seek opportunities to add high-coupon, high-quality bonds,
while intensifying our focus on attractively valued stocks of companies with
visible earnings growth and improving fundamentals.

year were particularly evident in the intermediate part of the yield curve. This
is evidenced by the wide yield fluctuations in the two-year Treasury note, which
rose by 1.52% during the second half of 1994, and rallied by 1.89% in the first
half of 1995.
 
     The Intermediate Bond Fund was able to outperform its benchmark during both
of these periods. In 1994, the Fund benefitted from a shorter average maturity,
large cash positions (as high as 18%), and large exposure to the mortgage-backed
securities market, which performed well on a relative basis in 1994.
 
     In late 1994, the Fund began to extend its average maturity and reduce its
cash position, allowing it to benefit from the broad market rally. It further
benefitted from its large holdings of asset-backed securities (as much as 23% of
the portfolio), which performed extremely well in 1995. A shortage of
high-quality corporate bonds allowed spreads to narrow significantly, compared
to Treasuries of similar maturity.
 
     The Fund has maintained its emphasis on credit quality, with over 85% of
its holdings being U.S. government and agency obligations or AAA-rated
securities. Recently, the Fund raised its cash position to 9.9%, due to the
relative unattractiveness of short-to-intermediate Treasuries, which currently
yield less than cash equivalents. We expect this to be a temporary holding.
 
     Looking to the rest of 1995, we expect the Fed to follow through on market
expectations and reduce short-term rates by at least another 25 basis points. A
steepening of the yield curve should accompany this action, creating a more
friendly environment for mortgage-backed securities.
 
     While a further drop in rates is possible, we would also expect volatility
in the fixed-income markets to subside. This would place more emphasis on yield
enhancement, rather than price movement, as a source of investor return.

beginning January 4, 1993. The performance shown for Intermediate Bond Portfolio
Series B (synthetic) prior to that date is based on the performance of
Institutional Series A shares adjusted to reflect the maximum sales charge of

commenced operations on February 3, 1992.

 
                             PA MUNICIPAL BOND FUND
 
     The PA Municipal Bond Fund, Series A, provided its shareholders with a
return of 7.50% for the 12 months ended June 30, 1995. This compared to a return
for the Lehman PA State Bond Index of 8.84% in the same period. For Series B
shares from which a sales charge has been deducted, the return was 2.41%; for
those without a load, the return was 7.25%.
 
     As of June 30, 1995, the 30-day yield was 5.39% and 4.90%, respectively,
for A and B shares. Assets in the Fund increased from $597,000 to $2,589,000.
 
     The Fund's lower performance, relative to the benchmark index, was mainly
due to supply factors. During the third quarter of 1994, the Fund grew
dramatically. At that time, supply of municipal bonds was very light (down 40%
from 1993). This forced managers to carry unusually high cash levels due to a
lack of coupon income.
 
     In the municipal bond market was driven mostly by ebbs and flows in demand
during the year. In late 1994, many tax-exempt mutual funds experienced large
withdrawals, because of the bond market's poor performance. As dealer
inventories swelled, demand for bonds decreased and prices fell. Then, when
Orange County, CA declared bankruptcy, investors temporarily fled the munibond
market, causing prices to drop further.
 
     In the first half of 1995, yields on fixed-income securities fell, as the
economy showed signs of a slowdown. The municipal bond market has been unable to
attract investors, and has underperformed the Treasury market as a result.
Demand has been slowed by concern over enactment of a flat tax, the Orange
County default, and the strong appeal of the stock market.

     We believe the Fed will lower interest rates further if inflation remains
under control. In addition, the municipal bond market is technically positioned
to outperform the Treasury market in the coming months. We continue to seek
attractive opportunities to swap or make new purchases, as the market reacts to
these various factors.

QUICK FUND FACTS -- CASH RESERVE (6/30/95)
 
Inception Date: August 16, 1985
Portfolio Size: $527.92 million (A&B combined)
Average Weighted Maturity: 43 days
 
                                      B-8
<PAGE>
Seven Day Yield: 5.75 Series A
                    5.48 Series B
 
     The CoreFund Cash Reserve continued to offer strong returns to the
money-market investor during the period ending June 30, 1995. The annual total
return for Series A shares during that period was 5.15%. Series B shares, from
which a 12b-1 fee is deducted, had an annual return of 4.89%. These returns
compared favorably to that of the IBC/Donoghue's All-Taxable Money Fund Average,
which was 4.98% on June 30, 1995.
 
     The Cash Reserve experienced modest growth in assets during the period. The
Fund totaled $527,924,000 on June 30, 1995, up from $516,724,000 a year earlier.
 
     The average maturity of the portfolio had been as short as 28 days in the
first quarter of 1995. In a defensive move against declining rates, the average
maturity was then gradually extended. By June 30, it was 43 days.
 
     Portfolio structure of the Cash Reserve has favored commercial paper, due
to the widening spread of returns relative to other investment vehicles. As
spreads fluctuate, we will routinely evaluate the structure, to add value to the
portfolio.
 
     Interest rates appear to have peaked, and the negative tone of the forward
curve would indicate further reductions in rates. In coming months, we look for
further declines on the heels of the recent lowering of the Fed Funds rate. To
maintain yield, we will pursue an extension strategy with the Cash Reserve,
targeting an average weighted maturity of 50 to 55 days.
 
                                TREASURY RESERVE
 
QUICK FUND FACTS -- TREASURY RESERVE (6/30/95)
 
Inception Date: November 21, 1988
Portfolio Size: $500.82 million (A&B combined)
Average Weighted Maturity: 47 days
Seven Day Yield: 5.68 Series A
                    5.42 Series B
 
     During a period when short-term interest rates increased 50 basis points,
the Treasury Reserve continued to deliver excellent investment results for the
period ending June 30, 1995. Series A shares returned an effective average
annual yield of 4.98%. The six-month total return for Series A shares was 5.58%.
Series B shares returned an effective average annual yield of 4.72%. The
six-month total return for Series B shares, from which a 12b-1 fee has been
deducted, was 5.32%.
 
     Since June 30, 1994, the CoreFund Treasury Reserve increased in size by
1.7%. Assets as of June 30, 1995, totaled $500,818,000. The average maturity
increased by 13 days, to 47.
 
     Although assets increased by $8 million, the increase in maturities was
mainly due to the purchase of longer-term Treasury securities. These securities
were purchased in order to hedge against the possibility of an easing in
short-term rates by the Federal Reserve Board.
 
     As of this writing the Fed has lowered the funds rate by 25 basis points.
Economic data is expected to be mixed and inflation should remain under control
during the second half of 1995. Our near-term position remains biased towards a
gradual decline in short-term rates as long as inflationary pressures remain
subdued. For this reason we will continue to look for buying opportunities along
the treasury bill yield curve while keeping the average maturity in the 45 to 55
day range.

QUICK FUND FACTS -- TAX-FREE RESERVE (6/30/95)
 
Inception Date: April 16, 1991
Portfolio Size: $64.28 million (A&B combined)
Average Weighted Maturity: 34 days
Seven Day Yield: 3.56 Series A
                    3.30 Series B
 
     The CoreFund Tax-Free Reserve, Series A shares, returned 3.12% for the year
ending June 30, 1995. This compared favorably to the 3.11% return provided by
Donoghue's Tax-Free Fund during the same period. For Series B shares of the
CoreFund Tax-Free Reserve, from which a 12b-1 fee has been deducted, the return
for the same period was 2.86%.
 
     The average maturity of the Tax-Free Reserve was shortened from 44 to 34
days during the period, to take advantage of rising interest rates. Net assets
in the Tax-Free Reserve decreased 22% to $64,280,000 on June 30, 1995 from
$80,330,000 on December 31, 1994.
 
     The decrease in assets was caused by the volatility of the tax-exempt money
market. Although rates increased steadily throughout the year, the spread
between taxables and non-taxables widened. The taxable equivalent yields on many
tax-exempt money market securities did not compare favorably to their taxable
counterparts. This prompted crossover buyers to move out of their tax-exempt
funds, and into taxable funds.
 
     In coming months, management of the Fund will focus on extending the
average maturity, to pick up yield.

     CoreFunds Individual Shares may be exchanged for Individual Shares in any
other CoreFunds Portfolios. Shareholders who exchange into any CoreFunds
Portfolio that imposes a sales charge may be subject to such sales charge, if
applicable and not previously paid. With respect to the Conestoga Portfolios, a
shareholder who has paid a sales load on purchases of Retail Shares of an Equity
or Fixed Income Portfolio may exchange those Retail Shares for Retail Shares of
another Conestoga Equity or Fixed Income Portfolio at net asset value.
Shareholders of Retail Shares of the Conestoga Money Market Portfolios may
exchange these for Retail Shares of another Conestoga Money Market Portfolio at
net asset value. Shareholders who want to move investments in a Conestoga Money
Market Portfolio to a Conestoga Equity or Fixed Income Portfolio must follow the
redemption and purchase procedures for Retail Shares. If however, those Retail
Shares of a Conestoga Money Market Portfolio were acquired by a previous
exchange from Retail Shares of a Conestoga Equity or Fixed Income Portfolio,
these may be exchanged without payment of a sales charge. Exchanges are only
available in states where exchanges can lawfully be made from one Portfolio to
another, and must satisfy the requirements relating to the minimum initial
investment in a Portfolio. CoreFunds and Conestoga

E. RESPONSIBILITY FOR TELEPHONE INSTRUCTIONS
 
     The CoreFunds and Conestoga Portfolios, their administrators and their
distributors are not liable for any loss, liability, cost or expense for acting
upon telephone instructions that are reasonably believed to be genuine. In
attempting to confirm that telephone instructions are genuine, procedures are
used that are considered reasonable, which may include recording telephone
instructions and requesting information as to account registration such as the
shareholder account number and/or tax identification number (in the case of
CoreFunds) or sending confirmations within 72 hours of the exchange, verifying
the name in which an account is registered, the account number, and the account
holder's Social Security number, and sending proceeds only to the address of
record or to a previously authorized bank account (in the case of Conestoga).
 
                        II. DIVIDENDS AND DISTRIBUTIONS
 
     All CoreFunds Portfolios and Conestoga Portfolios distribute their net

            INTERIM INVESTMENT ADVISORY AND SUB-ADVISORY AGREEMENTS
                                    FORM OF
                     INTERIM INVESTMENT ADVISORY AGREEMENT
 
     AGREEMENT made as of _______________, 1996 between CONESTOGA FAMILY OF
FUNDS, a Massachusetts trust with transferrable shares (the 'Company'), and
Meridian Investment Company or its successor (the 'Investment Adviser').
 
     WHEREAS, the Company is registered as an open-end, diversified, management
investment company under the Investment Company Act of 1940, as amended ('1940
Act'); and
 
     WHEREAS, the Company desires to retain the Investment Adviser to furnish
investment advisory services to the Cash Management Fund, Tax-Free Fund, U.S.
Treasury Securities Fund, Equity Fund, Special Equity Fund, Bond Fund,
Intermediate Income Fund, Pennsylvania Tax-Free Bond Fund, Balanced Fund,
Short-Term Income Fund and International Equity Fund and such other investment
portfolios of the Company as the Company and the Investment Adviser may agree
upon from time to time (each, a 'Fund' and collectively, the 'Funds') and the
Investment Adviser represents that it is willing and possesses legal authority
to so furnish such services;
 
     NOW, THEREFORE, in consideration of the premises and mutual covenants
herein contained, it is agreed between the parties hereto as follows:
 
     1. Appointment. The Company hereby appoints the Investment Adviser to act
as investment adviser to the Fund or Funds identified on Schedule A hereto for
the period and on the terms set forth in this Agreement. The Investment Adviser
accepts such appointment and agrees to furnish the services herein set forth for
the compensation herein provided. Additional Funds may be added to this
Agreement from time to time by the parties executing a new Schedule A which
shall become effective upon its execution and shall supersede any Schedule A
having an earlier date.
 
     2. Delivery of Documents. The Company has furnished the Investment Adviser
with copies properly certified or authenticated of each of the following:
 
          (a) the Company's Agreement and Declaration of Trust, as executed on
     August 1, 1989 and as filed with the Secretary of State of the Commonwealth
     of Massachusetts on August 2, 1989, and all amendments thereto or
     restatements thereof;
 
          (b) the Company's Code of Regulations and any amendments thereto;
 
                                      D-1
<PAGE>
          (c) resolutions of the Company's Board of Trustees authorizing the
     appointment of the Investment Adviser and approving this Agreement;
 
          (d) the Company's Notification of Registration on Form N-8A under the
     1940 Act as filed with the Securities and Exchange Commission on August 9,
     1989 and any amendments thereto;
 
          (e) the Company's Registration Statement on Form N-1A under the
     Securities Act of 1933, as amended ('1933 Act') (File No. 33-30431) and
     under the 1940 Act as filed with the Securities and Exchange Commission and
     all amendments thereto; and
 
          (f) the most recent prospectus and Statement of Additional Information
     of each Fund (such prospectuses and Statement of Additional Information, as
     presently in effect, and all amendments and supplements thereto are herein
     collectively called the 'Prospectus').
 
     The Company will furnish the Investment Adviser from time to time with
copies of all amendments of or supplements to the foregoing.
 
     3. Management. Subject to the supervision of the Company's Board of
Trustees, the Investment Adviser will provide a continuous investment program
for each Fund, including investment research and management with respect to all
securities and investments and cash equivalents in said Funds. The Investment
Adviser will determine from time to time what securities and other investments
will be purchased, retained or sold by the Company with respect to each Fund.
The Investment Adviser will provide the services under this Agreement in
accordance with each Fund's investment objective, policies, and restrictions as
stated in the Prospectus and resolutions of the Company's Board of Trustees. The
Investment Adviser further agrees that it:
 
          (a) will use the same skill and care in providing such services as it
     uses in providing services to other accounts for which it has investment
     responsibilities;
 
          (b) will conform with all applicable Rules and Regulations of the
     Securities and Exchange Commission and in addition will conduct its
     activities under this Agreement in accordance with any applicable
     regulations of any governmental authority pertaining to the investment
     advisory activities of the Investment Adviser;
 
          (c) will not make loans to any person to purchase or carry units of
     beneficial interest in the Company or make interest-bearing loans to the
     Company;
 
          (d) will place orders pursuant to its investment determinations for
     the Company either directly with the issuer or with any broker or dealer.
     In placing orders with brokers and dealers, the Investment Adviser will
     attempt to obtain prompt execution of orders in an effective manner at the
     most favorable price. Consistent with this obligation, when the execution
     and price offered by two or more brokers or dealers are comparable, the
     Investment Adviser may, in its discretion, purchase and sell portfolio
     securities to and from brokers and dealers who provide the Investment
     Adviser with research advice and other services; In no instance will
     portfolio securities be purchased from or sold to SEI Financial Management
     Corporation, SEI Financial Services Company, the Investment Adviser, or any
     affiliated person of either the Company, SEI Financial Management
     Corporation, SEI Financial Services Company, or the Investment Adviser;
 
          (e) will maintain all books and records with respect to the Company's
     securities transactions and will furnish the Company's Board of Trustees
     such periodic and special reports as the Board may request;
 
          (f) will treat confidentially and as proprietary information of the
     Company all records and other information relative to the Company and
     prior, present, or potential interestholders, and will not use such records
     and information for any purpose other than performance of its
     responsibilities and duties hereunder, except after prior notification to
     and approval in writing by the Company, which approval shall not be
     unreasonably withheld and may not be withheld where the Investment Adviser
     may be exposed to civil or criminal contempt proceedings for failure to
 
                                      D-2
<PAGE>
     comply, when requested to divulge such information by duly constituted
     authorities, or when so requested by the Company; and
 
          (g) will maintain its policy and practice of conducting its fiduciary
     functions independently. In making investment recommendations for the
     Company, the Investment Adviser's personnel will not inquire or take into
     consideration whether the issuers of securities proposed for purchase or
     sale for the Company's account are customers of the Investment Adviser or
     of its parent or its subsidiaries or affiliates. In dealing with such
     customers, the Investment Adviser and its parent, subsidiaries, and
     affiliates will not inquire or take into consideration whether securities
     of those customers are held by the Company.
 
     4. Assistance. The Investment Adviser may employ or contract with other
persons to assist it in the performance of this Agreement (herein, a
'Sub-Adviser'); provided, however, that the retention of any Sub-Adviser shall
be approved as may be required by the 1940 Act. A Sub-Adviser may perform under
the supervision of the Investment Adviser any or all services described under
Section 3. Sub-Advisers may include other investment advisory or management
firms and officers or employees who are employed by both the Investment Adviser
and the Company. The fees or other compensation of any Sub-Adviser shall be paid
by the Investment Adviser and no obligation may be incurred on the Company's
behalf to any such person.
 
     In the event that the Investment Adviser appoints a Sub-Adviser, the
Investment Adviser will review, monitor, and report to the Company's Board of
Trustees on the performance and investment procedures of any such Sub-Adviser;
assist and consult with any Sub-Adviser in connection with the Fund's continuous
investment program; and approve lists of foreign countries which may be
recommended by any Sub-Adviser for investment by the Fund.
 
     5. Services Not Exclusive. The investment management services furnished by
the Investment Adviser hereunder are not to be deemed exclusive, and the
Investment Adviser shall be free to furnish similar services to others so long
as its services under this Agreement are not impaired thereby.
 
     6. Books and Records. In compliance with the requirements of Rule 31a-3
under the 1940 Act, the Investment Adviser hereby agrees that all records which
it maintains for the Company are the property of the Company and further agrees
to surrender promptly to the Company any of such records upon the Company's
request. The Investment Adviser further agrees to preserve for the periods
prescribed by Rule 31a-2 under the 1940 Act the records required to be
maintained by Rule 31a-1 under the 1940 Act.
 
     7. Expenses. During the term of this Agreement, the Investment Adviser will
pay all expenses incurred by it in connection with its activities under this
Agreement other than the cost of securities (including brokerage commissions, if
any) purchased for the Company.
 
     8. Compensation. For the services provided and the expenses assumed
pursuant to this Agreement, each Fund will pay the Investment Adviser and the
Investment Adviser will accept as full compensation therefor a fee equal to the
lesser of (i) the fee computed daily and paid monthly at the applicable annual
rate set forth on Schedule A hereto, or (ii) such fee as may from time to time
be agreed upon in writing by the Company and the Investment Adviser in advance
of the period to which the fee relates. Each Fund's obligation to pay the
above-described fee to the Investment Adviser will begin as of the date of the
initial public sale of shares in that Fund.
 
     If in any fiscal year the aggregate expenses of any Fund (as defined under
the securities regulations of any state having jurisdiction over the Company)
exceed the expense limitations of any such state, the Investment Adviser will
reimburse such Fund for a portion of such excess expenses equal to such excess
times the ratio of the fees otherwise payable by such Fund to the Investment
Adviser hereunder to the sum of the aggregate fees otherwise payable by the Fund
to the Investment Adviser hereunder and to SEI Financial Management Corporation
under the Administration Agreement between SEI Financial Management Corporation
and the Company. The obligation of the Investment Adviser to reimburse the Funds
hereunder is limited in any fiscal year to the amount of its fee hereunder for
such fiscal year, provided, however, that notwithstanding the foregoing, the
Investment
 
                                      D-3
<PAGE>
Adviser shall reimburse the Funds for such proportion of such excess expenses
regardless of the amount of fees paid to it during such fiscal year to the
extent that the securities regulations of any state having jurisdiction over the
Company so require. Such expense reimbursement, if any, will be estimated daily
and reconciled and paid on a monthly basis.
 
     The fee attributable to each Fund shall be the several (and not joint or
joint and several) obligation of each such Fund.
 
     9. Limitation of Liability. The Investment Adviser shall not be liable for
any error of judgment or mistake of law or for any loss suffered by any Fund in
connection with the performance of this Agreement, except a loss resulting from
a breach of fiduciary duty with respect to the receipt of compensation for
services or a loss resulting from willful misfeasance, bad faith or gross
negligence on the part of the Investment Adviser in the performance of its
duties or from reckless disregard by it of its obligations and duties under this
Agreement.
 
     10. Duration and Termination. This Agreement will become effective as to a
Fund as of the date first written above, provided that it shall have been
approved by vote of a majority of the outstanding voting securities of such Fund
in accordance with the requirements under the 1940 Act, and, unless sooner
terminated as provided herein, shall continue in effect for two years after such
effective date. Thereafter, if not terminated, this Agreement shall continue in
effect as to each Fund for successive yearly periods, provided that such
continuance is specifically approved at least annually (a) by the vote of a
majority of those members of the Company's Board of Trustees who are not parties
to this Agreement or interested persons of any party to this Agreement, cast in
person at a meeting called for the purpose of voting on such approval, and (b)
by the vote of a majority of the Company's Board of Trustees or by the vote of a
majority of the outstanding voting securities of such Fund. Notwithstanding the
foregoing, this Agreement may be terminated as to a particular Fund at any time
on 60 days' written notice, without the payment of any penalty, by the Company
(by vote of the Company's Board of Trustees or by vote of a majority of the
outstanding voting securities of such Fund) or by the investment Adviser. This
Agreement will immediately terminate in the event of its assignment. (As used in
this Agreement, the terms 'majority of the outstanding voting securities,'
'interested persons' and 'assignment' shall have the meaning given to such terms
by the 1940 Act.)
 
     11. Amendment of this Agreement. No provision of this Agreement may be
changed, discharged or terminated orally, but only by an instrument in writing
signed by the party against which enforcement of the change, discharge or
termination is sought.
 
     12. Miscellaneous. The captions in this Agreement are included for
convenience of reference only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect. If any
provision of this Agreement shall be held or made invalid by a court decision,
statute, rule or otherwise, the remainder of this Agreement shall not be
affected thereby. This Agreement shall be binding upon and shall inure to the
benefit of the parties hereto and their respective successors and shall be
governed by the law of the Commonwealth of Pennsylvania.
 
     The names 'Conestoga Family of Funds' and 'Trustees of Conestoga Family of

Trust dated August 1, 1989 which is hereby referred to and a copy of which is on
file at the office of the State Secretary of The Commonwealth of Massachusetts
and at the principal office of the Trust. The obligations of 'Conestoga Family
of Funds' entered into in the name or on behalf thereof by any of the Trustees,
representatives or agents are made not individually, but in such capacities, and
are not binding upon any of the Trustees, shareholders or representatives of the
Trust personally, but bind only the Trust Property, and all persons dealing with
any class of shares of the Trust must look solely to the Trust Property
belonging to such class for the enforcement of any claims against the Trust.
 
     IN WITNESS WHEREOF, the parties hereto have caused this instrument to be
executed by their duly authorized officers designated below as of the day and

                                    FORM OF
 
                         INTERIM SUB-ADVISORY AGREEMENT
 
     AGREEMENT made as of _______________, 1996 between Meridian Investment
Company or its successor (the 'Adviser') and Marvin and Palmer Associates, Inc.
(the 'Sub-Adviser').
 
     WHEREAS, Conestoga Family of Funds (the 'Company') is registered as an
open-end diversified, management investment company under the Investment Company
Act of 1940, as amended ('1940 Act'); and
 
     WHEREAS, the Adviser desires to retain the Sub-Adviser to furnish
investment advisory services to the Company's International Equity Fund (the
'Fund') and the Sub-Adviser represents that it is willing and possesses legal
authority to so furnish such services;
 
     NOW, THEREFORE, in consideration of the premises and mutual covenants
herein contained, it is agreed between the parties hereto as follows:
 
     1. Appointment. The Advisor hereby appoints the Sub-Advisor to act as
Sub-adviser to the Fund for the period and on the terms set forth in this
Agreement. The Sub-Adviser accepts such appointment and agrees to furnish the
services herein set forth for the compensation herein provided.
 
     2. Delivery of Documents. The Adviser has furnished the Sub-Adviser with
copies properly certified or authenticated of each of the following:
 
          (a) the Company's Agreement and Declaration of Trust, as executed on
     August 1, 1989 and as filed with the Secretary of State of the Commonwealth
     of Massachusetts on August 2, 1989, and all amendments thereto or
     restatements thereof;
 
          (b) the Company's Code of Regulations and any amendments thereto;
 
          (c) resolutions of the Company's Board of Trustees authorizing the
     appointment of the Sub-Adviser, approving this Agreement, and establishing
     the investment objective, policies and restrictions of the Fund;
 
          (d) the Company's Notification of Registration on Form N-8A under the
     1940 Act as filed with the Securities and Exchange Commission on August 9,
     1989 and any amendments thereto;
 
          (e) the amendments to the Company's Registration Statement on Form
     N-1A under the Securities Act of 1933, as amended ('1933 Act'), (File No.
     33-30431) and under the 1940 Act relating to the Fund as filed with the
     Securities and Exchange Commission and all amendments thereto; and
 
          (f) the Fund's most recent prospectuses and Statement of Additional
     Information (such prospectuses and Statement of Additional Information, as
     presently in effect, and all amendments and supplements thereto are herein
     collectively called the 'Prospectus').
 
     The Adviser will furnish the Sub-Adviser from time to time with copies of
all amendments of or supplements to the foregoing.
 
     3. Duties of Sub-Adviser. Subject to the supervision of the Company's Board
of Trustees, the Sub-Adviser will assist the Adviser in providing a continuous
investment program for the Fund, including investment research and management
with respect to all securities and investments and cash equivalents of the Fund.
The Sub-Adviser will provide the services under this Agreement in accordance
with the Fund's investment objective, policies, and restrictions as stated in
the Prospectus and resolutions of the Company's Board of Trustees.
 
     Without limiting the generality of the foregoing, Sub-Adviser further
agrees that it will:
 
          (a) prepare, subject to the Adviser's approval, lists of foreign
     countries for investment by the Fund and determine from time to time what
     securities and other investments will be purchased,
 
                                      D-7
<PAGE>
     retained or sold for the Fund, including, with the assistance of the
     Adviser, the Fund's investments in futures and forward currency contracts;
 
          (b) manage in consultation with the Adviser the Fund's temporary
     investments in securities;
 
          (c) manage the Fund's overall cash position, and determine from time
     to time what portion of the Fund's assets will be held in different
     currencies;
 
          (d) provide the Adviser with foreign broker research, a quarterly
     review of international economic and investment developments, and
     occasional analyses on international investment issues;
 
          (e) attend regular business and investment-related meetings with the
     Company's Board of Trustees and the Adviser if requested to do so by the
     Company and/or the Adviser; and
 
          (f) maintain books and records with respect to the securities
     transactions for the Fund, furnish to the Adviser and the Company's Board
     of Trustees such periodic and special reports as they may request with
     respect to the Fund, and provide in advance to the Adviser all reports to
     the Company's Board of Trustees for examination and review within a
     reasonable time prior to the Company's Board meetings.
 
     4. Covenants by Sub-Adviser. Sub-Adviser agrees with respect to the
services provided to the Fund that it:
 
          (a) will use the same skill and care in providing such services as it
     uses in providing services to other accounts for which it has investment
     responsibilities, and will conform with all applicable Rules and
     Regulations of the Securities and Exchange Commission ('SEC Regulations')
     and in addition will conduct its activities under this Agreement in
     accordance with any applicable regulations of any governmental authority
     pertaining to the investment advisory activities of the Sub-Adviser;
 
          (b) will telecopy trade information to the Adviser on the first
     business day following the day of the trade and cause broker confirmations
     to be sent directly to the Adviser; and
 
          (c) will treat confidentially and as proprietary information of the
     Company all records and other information relative to the Fund and prior,
     present or potential shareholders, and will not use such records and
     information for any purpose other than performance of its responsibilities
     and duties hereunder (except after prior notification to and approval in
     writing by the Company, which approval may not be withheld where
     Sub-Adviser would be exposed to civil or criminal contempt proceedings for
     failure to comply, when requested to divulge such information by duly
     constituted authorities, or when so requested by the Company).
 
     5. Services Not Exclusive.
 
          (a) The services furnished by Sub-Adviser hereunder are deemed not to
     be exclusive, and nothing in this Agreement shall (i) prevent Sub-Adviser
     or any affiliated person (as defined in the 1940 Act) of Sub-Adviser from
     acting as investment adviser or manager for any other person or persons,
     including other management investment companies with investment objectives
     and policies the same as or similar to those of the Fund or (ii) limit or
     restrict Sub-Adviser or any such affiliated person from buying, selling or
     trading any securities or other investments (including any securities or
     other investments which the Fund is eligible to buy) for its or their own
     accounts or for the accounts of others for whom it or they may be acting;
     provided, however, that Sub-Adviser agrees that it will not undertake any
     activities which, in its reasonable judgment, will adversely affect the
     performance of its obligations to the Fund under this Agreement.
 
          (b) Nothing contained herein, however, shall prohibit Sub-Adviser from
     advertising or soliciting the public generally with respect to other
     products or services, regardless of whether such advertisement or
     solicitation may include prior, present or potential shareholders of the
     Company.
 
                                      D-8
<PAGE>
     6. Portfolio Transactions. Investment decisions for the Fund shall be made
by Sub-Adviser independently from those for any other investment companies and
accounts advised or managed by Sub-Adviser. The Fund and such investment
companies and accounts may, however, invest in the same securities. When a
purchase or sale of the same security is made at substantially the same time on
behalf of the Fund and/or another investment company or account, the transaction
will be averaged as to price, and available investments allocated as to amount,
in a manner which Sub-Adviser believes to be equitable to the Fund and such
other investment company or account. In some instances, this investment
procedure may adversely affect the price paid or received by the Fund or the
size of the position obtained or sold by the Fund. To the extent permitted by
law, Sub-Adviser may aggregate the securities to be sold or purchased for the
Fund with those to be sold or purchased for other investment companies or
accounts in order to obtain best execution.
 
   
     Sub-Adviser shall place orders for the purchase and sale of portfolio
securities and will solicit broker-dealers to execute transactions in accordance
with the Fund's policies and restrictions regarding brokerage allocations.
Sub-Adviser shall place orders pursuant to its investment determination for the
Fund either directly with the issuer or with any broker or dealer selected by
Sub-Adviser. In executing portfolio transactions and selecting brokers or
dealers, Sub-Adviser shall use its reasonable best efforts to seek the most
favorable execution of orders, after taking into account all factors Sub-Adviser
deems relevant, including the breadth of the market in the security, the price
of the security, the financial condition and execution capability of the broker
or dealer, and the reasonableness of the commission, if any, both for the
specific transaction and on a continuing basis. Consistent with this obligation,
Sub-Adviser may, to the extent permitted by law, purchase and sell portfolio
securities to and from brokers and dealers who provide brokerage and research
services (within the meaning of Section 28(e) of the Securities Exchange Act of
1934) to or for the benefit of the Fund and/or other accounts over which
Sub-Adviser or any of its affiliates exercises investment discretion.
Sub-Adviser is authorized to pay to a broker or dealer who provides such
brokerage and research services a commission for executing a portfolio
transaction for the Fund which is in excess of the amount of commission another
broker or dealer would have charged for effecting that transaction if
Sub-Adviser determines in good faith that such commission was reasonable in
relation to the value of the brokerage and research services provided by such
broker or dealer, viewed in terms of either that particular transaction or Sub-
Adviser's overall responsibilities to the Fund and to the Company. In no
instance will portfolio securities be purchased from or sold to Sub-Adviser, or
the Fund's principal underwriter, or any affiliated person thereof except as
permitted by SEC Regulations.
    
 
     7. Books and Records. In compliance with the requirements of Rule 31a-3
under the 1940 Act, Sub-Adviser acknowledges that all records which it maintains
for the Company are the property of the Company and agrees to surrender promptly
to the Company any of such records upon the Company's request, provided, that
Sub-Adviser may retain copies thereof at its own expense. Sub-Adviser further
agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act
the records required to be maintained by Rule 31a-1 under the 1940 Act.
 
     8. Expenses. During the term of this Agreement, Sub-Adviser will pay all
expenses incurred by it in connection with its activities under this Agreement
other than the cost of securities, commodities and other investments (including
brokerage commissions and other transaction charges, if any) purchased for the
Fund.
 
     9. Compensation. For the services provided by the Sub-Adviser pursuant to
this Agreement, the Adviser will pay to the Sub-Adviser a fee, payable monthly,
at the annual rates of seventy-five one-hundredths of one percent (0.75%) of the
average of the first $100,000,000 of the daily net assets of the Fund, seventy
one-hundredths of one percent (0.70%) of the average of the next $100,000,000 of
such assets, sixty-five one-hundredths of one percent (0.65%) of the average of
the next $100,000,000 of such assets, and sixty one-hundredths of one percent
(0.60%) of the average of such assets in excess of $300,000,000. If this
Agreement shall become effective subsequent to the first day of a month, or
shall terminate before the last day of a month, the Sub-Adviser's compensation
for such fraction of the month shall be determined by applying the foregoing
percentages to the average daily net asset value
 
                                      D-9
<PAGE>
of the Fund during such fraction of a month and in the proportion that such
fraction of a month bears to the entire month.
 
     10. Limitation of Liability. The Sub-Adviser shall not be liable for any
error of judgment or mistake of law or for any loss suffered by the Fund or the
Adviser in connection with the performance of this Agreement, except a loss
resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services or a loss resulting from willful misfeasance, bad
faith or gross negligence on the part of the Sub-Adviser in the performance of
its duties or from reckless disregard by it of its obligations and duties under
this Agreement.
 
     The Sub-Adviser agrees to indemnify the Adviser with respect to any loss,
liability, judgment, cost or penalty which the Fund or the Adviser may directly
or indirectly suffer or incur in any way arising out of or in connection with
any material breach of this Agreement by the Sub-Adviser. The Adviser agrees to
indemnify the Sub-Adviser with respect to any loss, liability, judgment, cost or
penalty which the Sub-Adviser may directly or indirectly suffer or incur in any
way arising out of the performance of its duties under this Agreement as
provided in the following paragraph.
 
     The Sub-Adviser shall give the Adviser the benefit of its best judgment and
effort in rendering services hereunder, but the Sub-Adviser shall not be liable
for any act or omission or for any loss sustained by the Adviser in connection
with the matters to which this Agreement relates, except a loss resulting from
willful misfeasance, bad faith or gross negligence in the performance of its
duties, or by reason of its reckless disregard of its obligations and duties,
under this Agreement. The Sub-Adviser shall be entitled to full indemnification
from the Adviser for any loss, liability, judgment, cost or penalty arising from
(a) any act by any person or entity (including the Adviser) for which the Sub-
Adviser was not involved directly in either the act itself or the decision
making process leading up to such act, (b) any act by the Sub-Adviser taken upon
the written instructions of the Adviser or (c) the performance of the
Sub-Adviser's duties under this Agreement; provided, however, the Sub-Adviser
shall not be entitled to indemnity under clause (c) of this sentence for any
loss, liability, judgment, cost or penalty resulting from willful misfeasance,
bad faith or negligence in the performance of its duties, or by reason of its
reckless disregard of its obligations and duties, under this Agreement.
 
     11. Duration and Termination. This Agreement will become effective as to
the Fund as of the date first written above, provided that it shall have been
approved by vote of a majority of the outstanding voting securities of the Fund
in accordance with the requirements under the 1940 Act, and, unless sooner
terminated as provided herein, shall continue in effect for two years after such
effective date. Thereafter, if not terminated, this Agreement shall continue in
effect for successive yearly periods, provided that such continuance is
specifically approved at least annually (a) by the vote of a majority of those
members of the Company's Board of Trustees who are not parties to this
Agreement, cast in person at a meeting called for the purpose of voting on such
approval, and (b) by the vote of a majority of the Company's Board of Trustees
or by the vote of a majority of the outstanding voting securities of the Fund.
Notwithstanding the foregoing, this Agreement may be terminated at any time on
60 days' written notice, without the payment of any penalty, by the Company (by
vote of the Company's Board of Trustees or by vote of a majority of the
outstanding voting securities of the Fund), by the Adviser, or by the
Sub-Adviser. This Agreement will immediately terminate in the event of its
assignment. (As used in this Agreement, the terms 'majority of the outstanding
voting securities,' 'interested persons' and 'assignment' shall have the meaning
given to such terms by the 1940 Act.)
 
     12. Amendment of this Agreement. No provision of this Agreement may be
changed, discharged or terminated orally, but only by an instrument in writing
signed by the party against which enforcement of the change, discharge or
termination is sought. No amendment of this Agreement shall be effective with
respect to the Fund until approved by the vote of a majority of the outstanding
voting securities of the Fund.
 
     13. Miscellaneous. The captions in this Agreement are included for
convenience of reference only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect. If any
provision of this Agreement shall be held or made invalid by a court decision,
statute,
 
                                      D-10
<PAGE>
rule or otherwise, the remainder of this Agreement shall not be affected
thereby. This Agreement shall be binding upon and shall inure to the benefit of
the parties hereto and their respective successors and shall be governed by the
law of the State of Delaware.
 
     IN WITNESS WHEREOF, the parties hereto have caused this instrument to be
