                          SHORT-INTERMEDIATE TERM FUND

                        TO BE HELD ON NOVEMBER 24, 1998

                   -----------------------------------------
    
I.  SYNOPSIS

       The following synopsis provides important information about the proposed
Consolidation. Before signing and returning the enclosed proxy ballot, you
should read this Combined Prospectus/Proxy Statement, including the Agreement
and Plan of Consolidation (Exhibit A), the performance information about the
Government Fund (Exhibit B), and the Government Fund's Prospectus.     

       The Funds.  Each Fund is a series of an open-end, management investment
       ---------                                                              
company organized as a Maryland corporation. The Government Fund retains its own
investment adviser and invests directly in a portfolio of securities.  Unlike
the Government Fund, the S-I Term Fund does not retain its own investment
adviser, but instead invests all of its assets in a series of another investment
company that may not be purchased by the general public - the Short-Intermediate
Term Master Portfolio (the "Master Portfolio"), a series of Managed Series
Investment Trust ("MSIT").  MSIT is an open-end, management investment company
organized as a Delaware business trust.  The Master Portfolio has the same
investment objective and policies as the S-I Term Fund and invests directly in a
portfolio of securities.  The S-I Term Fund pays its pro rata share of the
Master Portfolio's advisory fees.
    
       Proposed Consolidation.  At meetings held on September 2, 1998, the
       ----------------------                                                 
Boards of Directors of MasterWorks and Stagecoach (collectively, the "Boards"),
including the Directors who are not "interested persons" of MasterWorks or
Stagecoach (the "Independent Directors") within the meaning of the Investment
Company Act of 1940 (the "1940 Act"), approved an Agreement and Plan of
Consolidation (the "Consolidation Plan" or "Plan").  The Consolidation Plan
provides for the (i) in-kind redemption by the S-I Term Fund of its interest in
the Master Portfolio; (ii) transfer of all the assets of S-I Term Fund to the
Government Fund in exchange for Class A shares of the Government Fund; (iii)
assumption by the Government Fund of all the liabilities of the S-I Term Fund;
and (iv) distribution of the Class A shares of the Government Fund to
shareholders of S-I Term Fund (the "Consolidation").  The aggregate net asset
value of the Class A shares of the Government Fund issued in the Consolidation
will be equal to the net value of the assets and liabilities transferred by the
S-I Term Fund.     
    
       As a result of the Consolidation, each holder of S-I Term Fund shares
will receive that number of full and fractional Class A shares of the Government
Fund equal in net asset value at the close of business on the date of the
exchange to the net asset value of such holder's shares of the S-I Term Fund.
The Consolidation will be effected at net asset value without the imposition of
any sales charges.     

       The Board of each Fund has determined that (i) the interests of existing
shareholders of the Fund would not be diluted as a result of the Consolidation
and (ii) the Consolidation would be in the best interests of the Fund and its
shareholders.  Each Fund's Board recommends approval of the Consolidation.
Approval of the Consolidation Plan and the Consolidation by the S-I Term Fund
will require the affirmative vote of the holders of a majority of the
outstanding shares of the S-I Term Fund.  The Funds will bear the expenses
incurred in connection with the Consolidation.

       The Consolidation is expected to occur shortly after its approval by
shareholders of the S-I Term Fund.  Either Board, however, may terminate the
Consolidation Plan in its entirety at any time prior to the closing of the
Consolidation.
    
       Tax Consequences of the Consolidation.  In the opinion of Morrison &
       -------------------------------------                               
Foerster LLP, the Consolidation should be treated as a reorganization within the
meaning of section 368(a)(1) of the Internal Revenue Code of 1986, as amended
(the "Code").  Under this treatment, the Government Fund, the S-I Term Fund and
shareholders of the S-I Term Fund would not recognize gain or loss as a result
of the Consolidation. At Closing, it will be determined whether the transaction
will take effect under either subsection (C) or (D) of Section 368(a)(1) of the
Code.  For a further discussion of tax matters, see "Federal Income Tax
Consequences" at page 15, below.     
    
       Management of the Funds.  The investment adviser to the Government Fund
       -----------------------                                                
is Wells Fargo Bank, N.A. ("Wells Fargo Bank"). Wells Fargo Bank and
Stagecoach have retained Wells Capital Management, Inc. ("WCM") to act as
investment sub-adviser to the Government Fund.    
        
       Barclays Global Fund Advisors ("BGFA") serves as investment adviser to
the Master Portfolio.  BGFA and MSIT have retained Wells Fargo Bank to serve as
investment sub-adviser to the Master Portfolio. The S-I Term Fund does not
retain an investment adviser because it invests all of its assets in the Master
Portfolio. The S-I Term Fund bears its pro rata share of the Master
Portfolio's advisory fees.       

       Advisory, Distribution and Other Fees; Expense Ratios.  The Government
       -----------------------------------------------------                 
Fund has higher investment advisory fees and a higher expense ratio than the S-I
Term Fund.  In addition, the Government Fund, unlike the S-I Term Fund, pays
distribution or Rule 12b-1 fees.
    
       Dividends and Distributions.  Both Funds pay monthly dividends from net
       ---------------------------                                            
investment income and distribute capital gains, if any, at least annually.  Each
Fund allows shareholders to reinvest the dividends in the Fund or receive cash
payments.      
        
       Purchases, Redemptions and Exchanges. Each Fund offers its shares on
       ------------------------------------                                
business days at the public offering price or net asset value next determined
after receipt of a purchase order in proper form. However, Class A shares of
the Government Fund, unlike shares of the S-I Term Fund, have an initial sales
charge. There are several methods of reducing the initial sales charge on
Class A shares of the Government Fund. In some cases, such as in connection with
certain retirement benefit or pension accounts, the sales charge is waived
entirely. Both Funds permit redemptions of shares on business days at the net
asset value next determined after receipt of a redemption request in proper
form.      

       Both Funds have exchange privileges.  Class A shareholders of the
Government Fund may exchange their shares for shares of other series of
Stagecoach and certain other Classes of such series, whereas the S-I Term Fund
shareholders may exchange their shares only for shares of other single class
series of MasterWorks.

       Investment Objectives and Policies and Risk Factors.  The investment
       ---------------------------------------------------                 
objectives and policies of the Funds are generally similar. The Funds'
investment objectives are listed below.

OBJECTIVE:  Seeks to provide a total         OBJECTIVE:  Seeks to provide investors with
 return, before fees and expenses,           current income while preserving capital, by
 exceeding that of the Lehman Brothers       investing primarily in a portfolio
 Intermediate Government/Corporate Bond      consisting of short- to intermediate term
 Index.                                      securities issued or guaranteed by the U.S.
                                             Government, its agencies and
                                             instrumentalities.
- ------------------------------------------------------------------------------------------
</TABLE>
    
       The S-I Term Fund pursues its objective by investing all of its assets in
the Master Portfolio, which has the same investment objective and policies as
the Fund. The Master Portfolio invests directly in a portfolio of securities.
The Government Fund invests directly in a portfolio of securities and is not
part of a master-feeder structure.      

       The risks of investing in the S-I Term Fund are somewhat similar to those
of investing in the Government Fund.  Both Funds invest (the S-I Term Fund
invests through the Master Portfolio) in a mix of U.S. Government obligations,
corporate bonds and other securities.  Both Funds have an investment policy of
maintaining, under normal market conditions, a weighted average portfolio
maturity of between 2 and 5 years.
        
       There are certain differences in the risks of the Funds' investments. In
general, the S-I Term Fund is a slightly riskier investment than the
Government Fund because the S-I Term Fund has more flexibility to invest in
non-government obligations. The Government Fund must invest at least 65% of
its net assets in U.S. Government obligations or repurchase agreements
collateralized by U.S. Government obligations. The S-I Term Fund has no such
restriction and can invest a greater portion of its portfolio in corporate
bonds than the Government Fund. The corporate bonds the Funds may purchase are
"investment grade" i.e., rated in the top four investment categories by a 
Nationally Recognized Statistical Rating Organization ("NRSRO").      

       The S-I Term Fund is the only feeder fund of the Master Portfolio and
owns 99.99% of all the Master Portfolio's interests.  The pro rata fees paid to
the Master Portfolio would be the same if incurred directly by  the S-I Term
Fund.  Consequently, the risks and expenses of investing in the S-I Term Fund
would be virtually unchanged if the Fund were not part of a master-feeder
structure.  Therefore, when comparing the Funds, the master-feeder structure of
the S-I Term Fund is of little significance.  If the Consolidation is approved,
said structure will be dissolved.  The dissolution of the master-feeder
structure does not require separate shareholder approval and is expected to
occur as part of the proposed Consolidation.
    
       There are other differences between the Funds in terms of investment
strategies, as well as differences in fees and expenses, which are described in
detail below. In deciding whether to approve the Consolidation, you should
consider the differences between the investment objectives and policies of the
Funds as discussed under "Comparison of Investment Objectives, Policies and
Restrictions" below and in the prospectuses offering shares of the Funds.

COMPARISON OF FEES AND EXPENSES

       The following comparison is based on current information for the S-I Term
and Government Funds, restated to reflect voluntary fee waivers and expense
reimbursements that are expected to continue during the current fiscal year.
There can be no assurances that the waivers or reimbursements will continue
after the end of the current fiscal year.

_____________________________
*   The S-I Term Fund bears its pro rata share of management fees paid by the
    Master Portfolio.      
    
/1/ Before waivers or reimbursements, Management fees would be 0.50%.      
    
/2/ Before waivers or reimbursements, Other Expenses would be 0.76%.      
    
/3/ Before waivers or reimbursements, Total Fund Operating Expenses would be
    1.31%.      
        
       Annual Fund operating expenses for the Funds are based on amounts
incurred during the most recent fiscal year. In the case of the Government Fund,
these amounts are restated to reflect voluntary fee waivers and expense
reimbursements that are expected to continue during the current fiscal year.
There can be no assurances that waivers or reimbursements will continue. In the
case of the Government Fund, long-term shareholders could pay more in overall
sales charges than the economic equivalent of the maximum front-end sales charge
applicable to mutual funds sold by members of the National Association of
Securities Dealers, Inc. (the "NASD").      
    
       With respect to the S-I Term Fund, Stephens Inc. ("Stephens") and 
Barclays Global Investors, N.A. ("BGI") have agreed to assume all of the
ordinary operating expenses of the Fund (other than investment advisory fees,
portfolio transaction expenses and administrative fees). There is no similar
arrangement in place for the Government Fund, which means that, absent voluntary

                               -----------------
                                            
      Since the investment objectives, policies and strategies of the S-I Term
Fund  directly correspond to those of its Master Portfolio, the discussion below
relates to the various investments of and techniques employed by the Master
Portfolio.      

      Under normal market conditions, the Master Portfolio seeks to maintain an
average weighted portfolio maturity generally in the 2-to-5 year range.  In the
case of mortgage-related, asset-backed and similar securities, the Master
Portfolio uses the security's average life in calculating the Master Portfolio's
average maturity.  Under 

                                       4
<PAGE>
 
unusual market conditions, the Master Portfolio may shorten or lengthen its
average weighted portfolio maturity.
    
      Only investment-grade securities are considered for investment.  These
securities will be identified by their ratings according to one of two major
rating services, S&P and Moody's.  Each service classifies securities into broad
categories starting with "investment grade" at the top and ranging downward
through more speculative classes, including so-called "junk bonds," to
securities that are virtually worthless.  The "investment grade" category is
subdivided into four rating groups by both services.  The four rating groups are
called "AAA"/"Aaa," "AA"/"Aa," "A"/"A," and "BBB"/"Baa" by S&P and Moody's,
respectively.  Obligations with the lowest investment grade rating have
speculative characteristics, and changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than in the case of higher grade debt obligations.  The
Master Portfolio may invest in securities of all four rating groups; however,
most of the Master Portfolio's assets will be invested in securities that, at
the time of purchase, are rated in the third group or higher, denoted "A" or
better by both rating services.  Asset-backed securities are further restricted
to the top two rating groups at time of purchase.  Mortgage-related securities,
which are issued or guaranteed by U.S. Government agencies, are all currently
considered to be in the highest rating category.  Subsequent to its purchase by
the Master Portfolio, an issue of securities may cease to be rated or its rating
may be reduced below the minimum rating required for purchase by the Master
Portfolio.  Wells Fargo Bank, N.A. ("Wells Fargo Bank") will consider such an
event in determining whether the Master Portfolio should continue to hold the
obligation.  To the extent the Master Portfolio continues to hold such
obligations, it may be subject to additional risk of default.      

      The Master Portfolio seeks to emphasize those maturity segments or rating
groups that appear to offer the most favorable returns to their risks, within
the maturity and quality ranges described above.

      The Master Portfolio may invest some of its assets (no more than 10% of
total assets under normal market conditions) in high quality money market
instruments, which include U.S. Government obligations, obligations of domestic
and foreign banks, repurchase agreements, commercial paper (including variable
amount master demand notes) and short-term corporate debt obligations.  Such
investments are made on an ongoing basis to provide liquidity and, to a greater
extent on a temporary basis, when there is an unexpected or abnormal level of
investor purchases or redemptions of Master Portfolio's shares or when
"defensive" strategies are appropriate.

                              The Government Fund
                              -------------------
                                            
      Wells Fargo Bank, as the Government Fund's investment adviser, actively
manages a diversified portfolio consisting primarily of short-to-intermediate-
term U.S. Government obligations.  The Government Fund may invest in securities
of any maturity.  Under ordinary circumstances, the Government Fund expects to
maintain a dollar-weighted average maturity of between 2 and 5 years.  The
Government Fund seeks to preserve capital by shortening average maturity when
interest rates are expected to increase and to increase total return by
lengthening maturity when interest rates are expected to fall.      
    
      Under normal market conditions, the Government Fund invests at least 65% 
of total assets in U.S. Government obligations or repurchase agreements 
collateralized by U.S. Government obligations. The Government Fund also may 
invest: (i) in investment grade corporate debt securities, including 
asset-backed securities; (ii) up to 25% of its total assets in 
dollar-denominated debt of U.S. branches of foreign banks or foreign branches of
U.S. banks; (iii) in adjustable-rate mortgage securities and adjustable portions
of collateralized mortgage obligations; and (iv) in stripped Treasury 
securities. The Government Fund may hold no more than 5% of its total assets in 
securities downgraded below investment grade after being acquired.      

      The Government Fund may temporarily hold assets in cash or in money market
instruments, including U.S. Government obligations, shares of other mutual funds
and repurchase agreements, or make other short-term investments, either to
maintain liquidity or for short-term defensive purposes when the adviser
believes it is in the best interest of shareholders to do so.  In addition, the
Government Fund may invest in forward currency exchange contracts to try to
reduce currency exchange risks and from foreign securities investments.

and officers of MasterWorks.  Stephens and BGI have agreed to assume all of the
ordinary operating expenses of the S-I Term Fund (other than investment advisory
fees, portfolio transaction expenses and administrative fees).  For these
services and the assumption of expenses, Stephens and BGI are entitled to a

       Distribution and Shareholder Servicing Arrangements.  Shares of the S-I
       ---------------------------------------------------                    
Term Fund and the Government Fund are distributed by Stephens, a full service
broker-dealer, pursuant to a distribution agreement.  Pursuant to Rule 12b-1
under the 1940 Act, Stagecoach has adopted a Distribution Plan on behalf of the
Class A shares of the Government Fund (the "Distribution Plan").  The
Distribution Plan allows the Government Fund to pay up to 0.05% of its average
daily net assets annually for the reimbursement of actual expenses incurred for
distribution and shareholder services ("Rule 12b-1 fees"). There are no 
Rule 12b-1 fees or front-end sales charges associated with an investment in the
S-I Term Fund.     
        
       The Directors of MasterWorks and Stagecoach also have approved
Shareholder Servicing Plans for the S-I Term Fund and Government Fund (the
"Servicing Plans"), respectively, pursuant to which they have entered into
Shareholder Servicing Agreements. For these services, the S-I Term Fund and the
Government Fund may pay a monthly fee equal to 0.10% and 0.30%, respectively, of
the average daily net assets of such Fund represented by shares owned during the
period for which payment is being made by investors with whom the Shareholder
Servicing Agent maintains a servicing relationship, or an amount which equals
the maximum amount payable to the Shareholder Servicing Agent under applicable
laws, regulations or rules, including the Conduct Rules of the NASD, whichever
is less. For the fiscal years ended February 28, 1998 and June 30, 1998, the S-I
Term Fund and the Government Fund, respectively, paid shareholder servicing
fees, after waivers and reimbursements, as follows:

COMPARISON OF PURCHASE AND REDEMPTION PROCEDURES AND OTHER CONSIDERATIONS      
    
       Sales Loads: The single class shares of the S-I Term Fund do not have a
       ------------                                                           
sales load.  The Class A shares of the Government Fund have a front-end sales
load of 3.00%. The sales load is reduced in connection with certain volume
purchases and is waived under certain other circumstances, such as in connection
with certain retirement, benefit and pension plans.  There are no sales charges
on reinvested distributions.      

       Minimum Investments:  The S-I Term Fund requires a minimum investment
       -------------------                                                  
amount of $1 million from direct buyers, although the requirement may be waived
under certain circumstances. The Government Fund requires a minimum investment
of $1,000 from direct buyers and additional investments in the Fund must be at
least $100. Both Funds typically waive the minimum in connection with
retirement, benefit and pension plans.

       Purchases:  Both Funds' shares may be purchased by mail, by wire or by
       ----------                                                            
phone, directly from the Fund, through a brokerage account with an approved
selling or shareholder servicing agent, through certain retirement, benefit and
pension plans, or through certain packaged investment products.  Both Funds
process requests at net asset value on the same day if the request is proper and
received before 1 p.m. on a business day.  In addition, Class A shares of the
Government Fund may be purchased or redeemed monthly through various automated
programs such as the AutoSaver and Systematic Withdrawal Plans and other
dividend reinvestment and payment plans.  Shareholder servicing agents with
Approved Bank Accounts may transmit orders for S-I Term Fund shares on behalf of
qualified buyers through the transfer agent.
    
       Redemptions:  Investors may redeem their shares free of charge on any
       -----------                                                          
business day by mail or telephone.  Redemption proceeds are calculated at the
next determined net asset value after a proper request is received, and are
remitted generally within seven days.  Benefit, pension, retirement and similar
plan investors usually have separate established withdrawal procedures.
Proceeds may be sent by check or credited to a designated account for certain
investors.  There is a $5,000 minimum redemption request for wiring redemptions
to an ACH linked bank account for the Government Fund.      

       Exchanges: Exchanges between the single class of shares of the S-I Term
       ---------                                                              
Fund and single class shares of other MasterWorks Funds are at the next
determined net asset value and there are no fees for exchanging. The Class A
shares of the Government Fund similarly may be exchanged for Class A shares of
other Stagecoach Funds, but will pay a sales load differential where such shares
are exchanged for Class A shares with a higher front-end sales load.  Exchanges
also are permitted between Class A shares and certain other classes of shares of
Stagecoach Funds.
        
       Dividends and Distributions: Both Funds pay monthly dividends from net
       ---------------------------
investment income and distribute capital gains, if any, at least annually. Each
Fund allows shareholders to reinvest the dividends in the Fund or receive cash
payments. In addition, the Government Fund offers the option to automatically
invest dividends in shares of other Stagecoach Funds. There is no sales or other
charge for either Fund in connection with the reinvestment of dividends or
distributions.

RISK CONSIDERATIONS      
    
       Each Fund is subject to credit risk and interest rate risk on investments
in debt securities. Credit risk is the possibility that an issuer of a security
will be unable to make interest payments or repay principal.  Interest rate risk
is the possibility that interest rates may increase and reduce the resale value
of securities in a Fund's portfolio. Interest rate increases usually result in a
decrease in the value of debt securities.   Each Fund maintains an average
weighted portfolio maturity of 2 - 5 years, resulting in similar exposure to
interest rate risk.      
    
       The Government Fund invests primarily in obligations of the U.S.
Government, its agencies and instrumentalities, which are subject to interest
rate risk, but have low credit risk.  Some U.S. Government obligations are
backed by the full faith and credit of the United States, while others are only
backed by the agency or instrumentality that issues or guarantees the
instrument.  The U.S. Government does not guarantee the market value or current
yield of its obligations.      
    
       The S-I Term Fund invests, through the Master Portfolio, in a mix of U.S.
Government obligations and in corporate bonds that are rated in the top four
rating categories by an NRSRO.  A portion of the Government Fund's assets also
is generally invested in corporate bonds.  Corporate bonds expose investors to
greater credit risk than U.S. Government obligations and are generally higher
yielding.  The table below provides a snapshot of the portfolio composition of
the Funds.  The S-I Term Fund generally invests a larger portion of its assets
in corporate bonds, exposing it, on average, to greater credit risk than the
Government Fund.      
    
       The following table compares the investment allocations of the Funds as
of June 30, 1998.

                         Additional Risk Considerations 
                         ------------------------------      
    
       The Funds may only purchase investment grade securities, but each  may 
hold securities in its portfolio that have been downgraded below investment
grade after purchase. The Government Fund has a policy of holding no more than
5% of its total assets in such securities, while the S-1 Term Fund has no such
limitation. As of June 30, 1998, neither Fund held any securities that were
below investment grade. Non-investment grade securities may be more
sensitive to economic conditions and have higher interest rate and credit
risk.     
    
       The S-I Term Fund may enter into futures transactions, and each Fund may
invest in certain floating- and variable-rate securities. Some of these and
other portfolio securities may be considered derivatives, which may be more
sensitive than direct securities to changes in interest rates and sudden market
moves.  The Government Fund may invest in Stripped Treasury Securities, which
may have greater interest rate risk than traditional government securities with
identical credit ratings.  Neither Fund intends to have more than 5% of its net
assets invested in derivatives at any given time.      
    
       Each Fund may invest up to 25% of its assets in high-quality, U.S. dollar
denominated obligations of foreign branches of U.S. banks and U.S. branches of
foreign banks.      
    
       Market risk is the risk that the value of a bond or other security will
be reduced by market activity.  By investing to a greater extent in corporate
bonds, the S-I Term Fund has greater market risk exposure than the Government
Fund.  Counter party risk is the risk that the other party in a repurchase
agreement or other transaction will not fulfill its contract obligation.  Both
Funds invest in repurchase agreements.  In addition, some of the asset-backed
securities in which the Funds invest are subject to extension risk, which is the
risk that when interest rates rise, prepayments of the underlying obligations
slow, thereby lengthening the duration and potentially reducing the value of
these securities.      
    
                                *    *    *    *      
    
       Because the investment objective, policies, strategies and restrictions
of the S-I Term Fund and the Government Fund are generally similar, the overall
level of investment risk should not materially change as a result of the
Consolidation.  For a more complete description of the Government Fund's and the
S-I Term Fund's investment policies and restrictions, see "The Funds" in each
Fund's Prospectus and "Additional Permitted      

                                       12
<PAGE>
 
        
Investments" in each Fund's Statement of Additional Information. In view of
the fact that the assets of the S-I Term Fund amount to less than 10% of the
assets of the Government Fund, in addition to the fact that the Funds invest
in similar securities, it is not anticipated that any material portfolio
realignment or divestiture of securities will be necessary subsequent to the
Closing. Changes to the schedule of investments resulting from the
Consolidation, if any, are expected to be de minimis.     
        
III.  DESCRIPTION OF THE CONSOLIDATION PLAN      
         
       The Plan provides that all of the assets of the S-I Term Fund as of the
Closing Date will be transferred to the Government Fund, and that the Government
Fund will assume all of the liabilities of the S-I Term Fund, in exchange for
Class A shares of the Government Fund. The "Closing Date" is expected to be on
or about December 4, 1998. A copy of the Plan is attached as Exhibit A to this
Combined Prospectus/Proxy Statement.      
        
       Promptly after the Closing Date, the S-I Term Fund will distribute the
shares of the Government Fund received to the S-I Term Fund's shareholders of
record as of the close of business on the Closing Date.  The shares of the
Government Fund that will be issued for distribution to the S-I Term Fund's
shareholders will be equal in value to the shares of the S-I Term Fund held as
of the Closing Date.  MasterWorks will then take all necessary steps to
terminate the qualification, registration and classification of the S-I Term
Fund.  All issued and outstanding shares of the S-I Term Fund will be cancelled
on the S-I Term Fund's books.  Shares of the Government Fund will be represented
only by book entries; no share certificates will be issued unless expressly
requested in writing.  Certificates are not issued for fractional shares.  All
remaining organizational expenses of the S-I Term Fund will be offset against
the original shares of such Fund prior to the Consolidation.      
    
       The consummation of the proposed Consolidation is subject to the
satisfaction of a number of conditions set forth in the Plan, including approval
by the shareholders of the S-I Term Fund.  The S-I Term Fund may waive certain
conditions at any time before or after approval of the Plan by the shareholders.
The Plan also may be terminated and the Consolidation abandoned at any time by
the mutual written consent of MasterWorks and Stagecoach or by either party if
any of the conditions precedent to the Closing are not satisfied.  The
Consolidation also is subject to the condition, which cannot be waived, of
obtaining an opinion of counsel to the effect that the Consolidation constitutes
a tax-free reorganization for federal income tax purposes.      
    
       Shareholders of the S-I Term Fund will have no dissenters' rights or
appraisal rights.  All shareholders of the S-I Term Fund as of the Closing Date,
including those that vote against the approval of the Plan and those that do not
vote, will receive shares of the Government Fund if the Consolidation is
approved.  All shareholders of the S-I Term Fund have the right at any time up
to the business day preceding the Closing Date to redeem their shares at net
asset value according to the procedures set forth in the S-I Term Fund's
Prospectus.  In addition, up until the business day preceding the Closing Date,
shareholders      

                                       13
<PAGE>
 
    
of the S-I Term Fund may exchange their shares for shares of other funds in the
MasterWorks Family of Funds, in accordance with the exchange privilege described
in the S-I Term Fund's Prospectus.      
    
BOARD CONSIDERATION      
    
       The business and affairs of MasterWorks and Stagecoach are managed under
the direction of their respective Boards of Directors. The Boards of Directors
of MasterWorks and Stagecoach each unanimously voted to approve the
Consolidation Plan at a meeting held on September 2, 1998. In reviewing the
proposed Consolidation, the Boards of MasterWorks and Stagecoach considered the
potential impact of the Consolidation on each Fund's shareholders. The Boards
considered, among other things: (i) the terms and conditions of the Plan,
including those intended to avoid the dilution of shareholder interests; (ii)
the potential marketing and shareholder benefits obtained by having a combined
fund; (iii) the similarity of the investment objectives and significant policies
and restrictions of the Funds; (iv) the historical investment performance of the
Funds; (v) the historical and projected investment advisory fee rates and
operating expenses of the Funds; (vi) the identity of the organizations that
provide investment advisory and certain other services to the Funds, and the
terms on which these services are provided; and (vii) the prospects for long-
term viability of the Funds.          

       Based upon their evaluation of these factors, and in light of their
fiduciary duties under federal and state law, the Boards of MasterWorks and
Stagecoach have determined that the proposed Consolidation is in the best
interests of the shareholders of the respective  Funds and that the interests of
the shareholders of the respective Funds will not be diluted as a result of the
Consolidation.  MASTERWORKS' BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
SHAREHOLDERS VOTE FOR THE PLAN OF CONSOLIDATION.      
                  ---                           
    
REASONS FOR THE CONSOLIDATION      
    
      The primary reason for the proposed Consolidation is to allow S-I Term
Fund investors to transfer their investment into a fund that has greater
prospects for long-term viability.  As of June 30, 1998, the S-I Term Fund had
only $11 million in net assets; the Government Fund had approximately $136
million in net assets. Management of MasterWorks believes that consolidating the
S-I Term Fund into a fund that has generally compatible investment objectives
and policies and greater prospects for continued growth, is a better alternative
than liquidation of the S-I Term Fund.          

      Combining the S-I Term Fund into a larger, more viable fund is intended to
provide various benefits to shareholders of the S-I Term Fund.  For example,
higher asset levels should benefit portfolio management by permitting larger
individual portfolio investments (in quantities that may result in reduced
transaction costs and/or more favorable pricing) and by providing the
opportunity for greater portfolio diversity.      

                                       14
<PAGE>
 
    
       Currently, the fees and expenses of the Government Fund are higher, on
both a before-waiver and after-waiver basis than those of the S-I Term Fund.
Nonetheless, your Board of Directors believes that the proposed Consolidation
will likely benefit S-I Term Fund shareholders for all of the reasons described
here.  One fee difference is that the Government Fund has a Rule 12b-1
distribution plan, which has been used to pay for distribution-related
activities that have contributed to the increase in this Fund's assets.  Another
difference is that BGI and Stephens have agreed to assume all of the ordinary
operating expenses of the S-I Term Fund (other than investment advisory fees,
portfolio transaction expenses and administrative fees), which, given the very
small size of the S-I Term Fund, requires BGI and Stephens, in effect, to
subsidize the S-I Term Fund's ongoing operations. There is no similar
arrangement in place for the Government Fund. See "Comparison of Fees and
Expenses" at page 2, above.      
    
      In short, management of MasterWorks believes that the proposed
Consolidation should provide S-I Term Fund shareholders with an investment
vehicle that has compatible investment objectives and policies and greater
prospects for long-term viability and continued growth.      
    
FEDERAL INCOME TAX CONSEQUENCES      
        
      The S-I Term Fund and the Government Fund each qualifies as a separate
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code"). Accordingly, the Funds have been, and expect to continue
to be, relieved of federal income tax liability.      
    
      As a condition to the Consolidation, MasterWorks and Stagecoach must
receive a favorable opinion from Morrison & Foerster LLP, counsel to MasterWorks
and Stagecoach, substantially to the effect that, for federal income tax
purposes, (a) the Consolidation will constitute a "reorganization" within the
meaning of Section 368(a)(1) of the Code (sub-item (C) or (D) to be determined
at closing), and the Government Fund and S-I Term Fund will each be a "party to
a reorganization," within the meaning of Section 368(b) of the Code, with
respect to the Consolidation; (b) no gain or loss will be recognized by the S-I
Term Fund as a result of the Consolidation; (c) no gain or loss will be
recognized by the Government Fund as a result of the Consolidation; (d) no gain
or loss will be recognized by the shareholders of the S-I Term Fund on the
distribution to them by the S-I Term Fund of shares of the Government Fund in
exchange for their shares of the S-I Term Fund; (e) the basis of the Government
Fund shares received by each shareholder of the S-I Term Fund will be the same
as the basis of the shareholder's S-I Term Fund shares immediately prior to the
Consolidation; (f) the basis of the Fund Assets received by the Government Fund
will be the same as the basis of such Fund Assets in the hands of the S-I Term
Fund immediately prior the Consolidation; (g) a shareholder's holding period for
Government Fund shares will be determined by including the period for which the
shareholder held the shares of the S-I Term Fund exchanged therefor, provided
that the shareholder held such shares of the S-I Term Fund as a capital asset;
(h) the holding period of the Government Fund with respect to the Fund Assets
will include the period for which such Fund Assets were held by     


                                       15
<PAGE>
 
    
the S-I Term Fund; and (i) the Government Fund will succeed to the tax
attributes of the S-I Term Fund described in Section 381(c) of the Code. The tax
attributes carried over to the Government Fund may include unused capital losses
of the S-I Term Fund. However, the use of such losses by the Government Fund may
be limited under several provisions of the Code.      
    
      Neither MasterWorks nor Stagecoach intends to seek a private letter ruling
from the Internal Revenue Service ("IRS") with respect to the tax effects of the
Consolidation.  The opinion of Morrison & Foerster LLP with respect to the tax
consequences of the Consolidation 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 of the
Consolidation to them, including any applicable foreign, state and local income
tax consequences.

ADDITIONAL INFORMATION      
    
       MasterWorks and Stagecoach are subject to certain informational
requirements of the Securities Exchange Act of 1934, as amended (the "1934
Act"), and the 1940 Act, and in accordance therewith each files reports, proxy
materials and other information with the SEC.  Such reports, proxy materials and
other information may be inspected and copied at the public reference
facilities of the SEC at 450 Fifth Street, N.W., Washington, D.C. 20549 and at
certain regional offices. Copies of such materials can be obtained from the
Public Reference Branch, Office of Consumer Affairs and Information Services,
Securities and Exchange Commission, 450 Fifth Street, N.W., Washington, D.C.
20549, at prescribed rates.

V.  VOTING INFORMATION      
    
APPROVAL AND CONSUMMATION OF THE PROPOSED TRANSACTION      
        
       Only shareholders of record at the close of business on October 9, 1998,
will be entitled to vote at the Special Meeting.  On that date, 1,153,033.682 S-
I Term Fund shares were outstanding and entitled to be voted.  The date of the
first mailing of this Combined Prospectus/Proxy Statement to shareholders is
approximately October 26, 1998.      
    
      Shareholders holding more than one-third of the outstanding shares of the
S-I Term Fund at the close of business on the Record Date will be deemed
sufficient to constitute a quorum for the transaction of business at the Special
Meeting.  Pursuant to Maryland law, the affirmative vote of the holders of a
majority of the outstanding voting securities of the S-I Term Fund is required
for approval of the Plan.  If the S-I Term Fund's shareholders do not approve
the proposed Consolidation, MasterWorks' Board of Directors will consider what
other alternatives would be in the shareholders' best interests, including
possibly, approving a Plan of Liquidation.      
    
       Any proxy which is properly executed and received in time to be voted at
the Special Meeting will be counted in determining whether a quorum is present
and will be voted in accordance with the instructions marked thereon. In the
absence of any instructions, such proxy will be voted in favor of the Plan.  Any
shareholder giving a proxy may revoke it at any time before it is exercised (i)
by submitting to MasterWorks a written notice of revocation, (ii) by submitting
to MasterWorks a subsequently executed proxy or (iii) by attending the Special
Meeting and voting in person.  Abstentions and "broker non-votes" (i.e., proxies
from brokers or nominees indicating that such persons have not received
instructions from the beneficial owners or other persons entitled to vote shares
as to a particular matter with respect to which the brokers or nominees do not
have discretionary power to vote) will not be counted for or against any proxy
to which they relate, but will be counted for purposes of determining whether a
quorum is present and will be counted as votes present at the Special Meeting.
For this reason, abstentions and broker non-votes will have the effect of a vote
against the proposal.      
    
      The duly appointed Proxies may, in their discretion, vote upon such other
matters as properly may come before the Special Meeting or any adjournment(s)
thereof, including any proposal to adjourn a meeting at which a quorum is
present to permit the continued solicitation of proxies in favor of the
Consolidation.  Any such adjournment(s) will require the affirmative vote of a
majority of the shares present in person or by proxy at the session of the
Special Meeting to be adjourned.  In case any such adjournment is proposed, the
duly appointed Proxies will vote those proxies which they are entitled to vote
for the Plan in favor of adjournment, and will vote those proxies required to be
voted against the Plan against adjournment.      

                                       19
<PAGE>
 
    
SOLICITATION OF PROXIES AND PAYMENT OF EXPENSES      
    
       It is expected that the solicitation of proxies will be primarily by
mail.  Officers and agents of MasterWorks and Stagecoach also may solicit
proxies by telephone, telegraph or personal interview.  Shareholders may vote by
(1) mail, by marking, signing, dating and returning the enclosed Proxy Ballot in
the enclosed postage-paid envelope; (2) telephone, by calling Shareholder
Communications Corp. ("SCC") toll-free at 1-800-733-8481, EXT. 448 FROM 6:00
A.M. TO 8:00 P.M. PACIFIC TIME; or (3) telefacsimile, by marking, signing,
dating and faxing the enclosed Proxy Ballot to SCC AT 1-800-733-1885.  SCC has
been retained by MasterWorks to assist in both the tabulation and solicitation
of proxy votes for the Consolidation.      
        
       The cost of soliciting proxies for the Special Meeting, consisting
principally of printing and mailing expenses, together with the costs of the
proxy soliciting services provided by SCC, will be borne jointly by the Funds
and is estimated to be approximately $1,500. Proxies will be solicited in the
initial, and any supplemental, solicitation by mail and may be solicited in
person, by telephone, telegraph, telefacsimile or other electronic means by
officers of MasterWorks, personnel of BGFA or Stephens, or an agent of
MasterWorks, such as SCC.          
    
VIII.   MISCELLANEOUS      

OTHER BUSINESS
    
       The Board of Directors of MasterWorks knows of no other business to
be brought before the Special Meeting.  However, if any other matters come
before the Special Meeting, including any proposal to adjourn the meeting to
permit the continued solicitation of proxies in favor of the Consolidation, it
is their intention that proxies which do not contain specific restrictions to
the contrary will be voted on such matters in accordance with the judgment of
the persons named in the enclosed Proxy Ballot.      

FUTURE SHAREHOLDER PROPOSALS
    
       Pursuant to rules adopted by the SEC under the 1934 Act, investors may
request inclusion in the Board's proxy statement for shareholder meetings
certain proposals for action which they intend to introduce at such meeting.
Any shareholder proposals must be presented a reasonable time before the proxy
materials for the next meeting are sent to shareholders. The submission of a
proposal does not guarantee its inclusion in MasterWorks's proxy statement and
is subject to limitations under the 1934 Act. Because MasterWorks does not
hold regular meetings of shareholders, no anticipated date of the next meeting
can be provided.

     WHEREAS, each of MasterWorks, MSIT and Stagecoach is an open-end management
investment company registered with the Securities and Exchange Commission (the

 ---                                                              --------   
and
 
     WHEREAS, the S-I Term Fund pursues its investment objective by investing
substantially all of its assets in the S-I Term Master Portfolio and the
Government Fund pursues its investment objective by investing directly in a
portfolio of securities; and
 
     WHEREAS, the parties desire that the assets and liabilities of the S-I Term
Fund be conveyed to, and be acquired and assumed by, the Government Fund, in
exchange for shares of equal value of the Government Fund which shall thereafter
promptly be distributed to the shareholders of the S-I Term Fund in connection
with its liquidation as described in this Plan (the "Consolidation"); and
                                                     -------------       
 
     WHEREAS, the parties intend that the Consolidation qualify as a
"reorganization," within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code"), and that Government Fund and S-I Term
                               ----                                         
Fund will each be a "party to a reorganization," within the meaning of Section
368(b) of the Code, with respect to the Consolidation;
 
     NOW, THEREFORE, in accordance with the terms and conditions described
herein, the S-I Term Fund and the Government Fund shall be consolidated as
follows:
 
   1.    Conveyance of Assets of S-I Term Fund.
         ------------------------------------- 

         (a) At the Effective Time of the Consolidation (as defined in Section
9), all assets of every kind, and all interests, rights, privileges and powers
of the S-I Term Fund, subject to all liabilities of the S-I Term Fund existing
as of the Effective Time of the Consolidation (the "Fund Assets"), shall be
                                                    -----------       
transferred and conveyed by the S-I Term Fund to the Government Fund and shall
be accepted and assumed by the Government Fund, as more particularly set forth
in this Plan, such that at and after the Effective Time of the Consolidation:
(i) all assets of the S-I Term Fund shall become and be the assets of the
Government Fund; and (ii) all liabilities of the S-I Term Fund shall attach to
the Government Fund, enforceable against the Government Fund to the same extent
as if initially incurred by it.

                                       1
<PAGE>
 
         (b) It is understood and agreed that the Fund Assets shall include all
property and assets of any nature whatsoever, including, without limitation, all
cash, cash equivalents, securities, claims (whether absolute or contingent,
known or unknown, accrued or unaccrued) and receivables (including dividend and
interest receivables) owned by the S-I Term Fund, and any deferred or prepaid
expenses shown as an asset on the S-I Term Fund's books and that the liabilities
of the S-I Term Fund shall include all liabilities, whether known or unknown,
accrued or unaccrued, absolute or contingent, in all cases, existing at the
Effective Time of the Consolidation.

         (c) It is understood and agreed that the S-I Term Master Portfolio will
liquidate the S-I Term Fund's interest in the S-I Term Master Portfolio through
an in-kind redemption, effective at or before the Effective Time of
Consolidation, so that the Fund Assets will consist primarily of the portfolio
securities held by the S-I Term Master Portfolio immediately before the
Effective Time of the Consolidation.

         (d) At least fifteen (15) business days prior to the Closing Date, (as
defined in Section 9), the S-I Term Master Portfolio will provide to the
Government Fund, a schedule of its securities and other assets and known
liabilities.  It is understood and agreed that the S-I Term Master Portfolio may
sell any of the securities or other assets shown on the list of assets prior to
the Effective Time of the Consolidation but will not, without the prior approval
of the Government Fund, acquire any additional securities other than securities
which the Government Fund is permitted to purchase in accordance with its stated
investment objective and policies.  At least ten (10) business days prior to the
Closing Date, the Government Fund will advise the S-I Term Master Portfolio of
any investments of the S-I Term Master Portfolio shown on such schedule which
the Government Fund would not be permitted to hold, pursuant to its stated
investment objective and policies or otherwise.  The S-I Term Master Portfolio,
if requested by the Government Fund, will dispose of any such securities prior
to the Closing Date to the extent practicable and consistent with applicable
legal requirements.  In addition, if it is determined that the portfolios of the
S-I Term Master Portfolio and the Government Fund, when aggregated, would
contain investments exceeding certain percentage limitations applicable to the
Government Fund, the S-I Term Master Portfolio, if requested by the Government
Fund, will dispose of a sufficient amount of such investments as may be
necessary to avoid violating such limitations as of the Effective Time of the
Consolidation.

       (e) The Fund Assets shall be transferred and conveyed to the Government
Fund on the following basis:
    
           (1) In exchange for the transfer of the Fund Assets, the Government
   Fund shall simultaneously issue to the S-I Term Fund at the Effective Time of
   the Consolidation full and fractional Class A Shares of Common Stock of
   the Government Fund having an aggregate net asset value equal to the net
   value of the Fund Assets so conveyed, all determined as provided in this
   Plan. In this regard, the number of full      

                                       2
<PAGE>
 
   and fractional shares of the Government Fund delivered to the S-I Term Fund
   shall be determined by dividing the value of the Fund Assets, computed in the
   manner and as of the time and date set forth in this Plan, by the net asset
   value of one Government Fund Class A Share, computed in the manner and as of
   the time and date set forth in this Plan.

           (2) The net asset value of shares to be delivered by the Government
   Fund, and the net value of the Fund Assets to be conveyed by the S-I Term
   Fund, shall, in each case, be determined as of the Valuation Time as defined
   in Section 3. The net asset value of Class A Shares of the Government Fund
   shall be computed in accordance with its then current valuation procedures.
   In determining the value of the Fund Assets, each security to be included in
   the Fund Assets shall be priced in accordance with the Government Fund's then
   current valuation procedures.

   2.    Liquidation of S-I Term Fund.  At the Effective Time of the
         ----------------------------                               
Consolidation, the S-I Term Fund shall make a liquidating distribution to its
shareholders as follows:  Shareholders of record of the S-I Term Fund shall be
credited with full and fractional shares of the Class A Shares of common stock
that are issued by the Government Fund in connection with the Consolidation
corresponding to the S-I Term Fund shares that are held of record by the
shareholder at the Effective Time of the Consolidation.  Each such shareholder
also shall have the right to receive any unpaid dividends or other distributions
which were declared before the Effective Time of the Consolidation with respect
to the S-I Term Fund shares that are held of record by the shareholder at the
Effective Time of the Consolidation, and Stagecoach shall record on its books
the ownership of the respective Government Fund shares by such shareholders.
All of the issued and outstanding shares of the S-I Term Fund at the Effective
Time of the Consolidation shall be redeemed and canceled on the books of
MasterWorks at such time.  As soon as reasonably possible after the Effective
Time of the Consolidation, MasterWorks shall wind up the affairs of the S-I Term
Fund and shall file any final regulatory reports, including but not limited to
any Form N-SAR and Rule 24f-2 filings, with respect to the S-I Term Fund, and
also shall take all other steps as are necessary and proper to effect the
termination or declassification of the S-I Term Fund in accordance with all
applicable laws.

   3.    Valuation Time.  The "Valuation Time" shall be the time as of which
         ---------------       --------------                               
the net asset value of shares of each of the S-I Term Fund and the Government
Fund is determined pursuant to the Government Fund's valuation procedures on the
Closing Date or such earlier or later time as may be mutually agreed to in
writing by the parties hereto.

   4.    Certain Representations, Warranties and Agreements of MasterWorks.
         -----------------------------------------------------------------  
MasterWorks, on behalf of itself and, where appropriate, the S-I Term Fund,
represents and warrants to, and agrees with, Stagecoach and MSIT as follows;
such representations, warranties and agreements being made on behalf of the S-I
Term Fund on a several (and not joint, or joint and several) basis:

                                       3
<PAGE>
 
         (a) MasterWorks is a corporation, duly created, validly existing and in
good standing under the laws of the State of Maryland. MasterWorks is registered
with the SEC as an open-end management investment company under the 1940 Act,
and such registration is in full force and effect.

         (b) MasterWorks has the power to own all of its properties and assets
and to consummate the transactions contemplated herein, 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 Plan.

     This Exhibit reproduces in its entirety the discussion of Fund performance
for Class A shares from the Government Fund's June 30, 1998, Annual Report.  The
discussion reviews some of the factors that affected the Fund's performance
during this fiscal year and shows the performance of the Fund for various
periods.  The discussion has not been updated to reflect events occurring after
June 30, 1998.      
    
SHORT-INTERMEDIATE U.S. GOVERNMENT INCOME FUND      
    
     The Stagecoach Short-Intermediate U.S. Government Income Fund (the "Fund")
seeks to provide investors with current income while preserving capital by
investing primarily in a portfolio consisting of short- to intermediate-term
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities.  Targeting bonds within this range helps to maximize the
Fund's income potential by investing in short- to intermediate-bonds with an
average maturity between two and five years.      
    
     Please note that we have changed the Fund's fiscal year-end to June 30 from
March 31.  We have made this change to improve our reporting process.  This
change will not impact the performance or objective of your investment.  Because
of the new year-end, this report is the second annual report we have sent you
over the last three months.  Our discussions will focus on the most recent
period, although we may also comment on longer-term performance.      
    
     On June 12, 1998, the Stagecoach Intermediate Bond Fund was merged into the
Stagecoach Short-Intermediate U.S. Government Income Fund.  The investment
objective and the investment policies for the Short-Intermediate U.S. Government
Income Fund did not change.  However, the consolidation of the two funds did
create Class B shares for the Short-Intermediate U.S. Government Income Fund. 
     
    
     The Fund is managed by Madeline Gish, who leads the taxable short-duration
team.  Her eight-year investment career includes specialization in managing
short-duration taxable portfolios and taxable money market mutual funds.      
    
PERFORMANCE SUMMARY      
    
     During the three-month reporting period, the Stagecoach Short-Intermediate
U.S. Government Income Fund's Class A net asset value increased from $9.95 on
March 31, 1998, to $9.97 on June 30, 1998.  The Fund distributed $0.13 per share
in dividend income and no capital gains were distributed during this period.
Keep in mind that past distributions are not predictive of future trends as
distributions will vary based on Fund portfolio earnings.      

     The Fund's distribution rate was 5.22% for Class A shares, based on an
annualization of June's monthly dividend of $0.045 per share and the maximum
offering price of $10.28 on June 30, 1998.

   section.
    
     For the three-month period ended June 30, 1998, the Class A shares of the
Short-Intermediate U.S. Government Income Fund returned 1.54%, excluding sales
charges.  For the same time period, the Fund's Institutional Class returned
1.56%.  Overall, we remained very competitive with our benchmark, the Lehman
Brothers Treasury Note Index, which returned 1.54% in the same period.  The
competitive performance of the Fund was due to several steps taken to implement
our total return strategy.  We decreased our mortgage exposure to decrease
exposure to interest rate risk for the Fund.  This was a result of the current
interest rate environment, where we've seen an increased prepayment risk in the
mortgage-backed securities sector as prepayment occurred when homeowners
refinanced out of their existing mortgages into ones with lower interest rates.
In addition, we maintained our exposure to higher yielding bonds, particularly
corporate bonds.  Keep in mind that past performance is no guarantee of future
results.      

PORTFOLIO REVIEW

     The Fund is managed with a total return strategy that attempts to balance
reasonable risk with competitive income and capital appreciation.  Investment
quality, maturity and duration are carefully examined as the Fund's managers
employ a top-down approach.  This approach involves analysis of historical
interest rate shifts in an attempt to predict changes in Federal Reserve policy,
which would ultimately affect the strategy of the Fund.

     As of June 30, 1998, the Fund held 45% of the portfolio in federal agency
securities.  This allocation helped to maintain a degree of stability and credit
quality for the Fund.  Some of these securities are backed by the full faith and
credit of the United States, which has never defaulted on interest or principal
payments.  As with all mutual funds, the Fund is guaranteed neither by the U.S.
Government nor any of its agencies.

     With 32% of the portfolio invested in corporate bonds on June 30, 1998, we
attempted to gain potential income and capital appreciation by maintaining a
high level of corporate exposure.  On a similar note, we slightly lowered our
exposure to mortgage-backed securities due to the increased prepayment risk
associated with the flat interest rate environment.

     To maintain liquidity, we held 16% of the portfolio in U.S. Treasury notes
at the end of the three month reporting period.  In this interest rate
environment, we determined it prudent to use these liquid assets to alter the
Fund's duration.  This strategy allowed the Fund to capture increased current
income while preserving capital.

     The majority of the securities in the top ten holdings were acquired during
the Fund's growth phase and contributed to its growth. Some are higher yielding
corporate bonds that contribute to the Fund's income level. Overall, these bonds
have longer durations, which helps to maximize the Fund's income potential but
also increases the Fund's volatility in a changing interest rate environment.

     Assets in the Short-Intermediate U.S. Government Income Fund increased due
to its consolidation with the Intermediate Bond Fund, which added over $57.7
million in assets.  The number of issues in the Fund also grew from 28 bonds and
notes on March 31, 1998 to 51 on June 30, 1998.  The additional assets have been
diversified according to the investment policies of the Fund, and should provide
current income for the portfolio.

STRATEGIC OUTLOOK

     The nation's economy continues to be healthy but we believe that it may
weaken over time.  The Asian crisis may cause further effects such as increasing
the strength of the U.S. dollar and slowing inflation.  Given these views, we do
not feel that the Federal Reserve Board will raise interest rates in the near
future.  We feel that long-term interest rates may drift lower and short-term
rates will remain stable.

     Based on this outlook, we intend to position the Fund with a longer
duration to capture the potential for income and capital appreciation.  Our
management team has extensive experience in the bond market, enabling us to
respond quickly to economic conditions and market events.  We will continue to
watch the events in Asia and monitor the region's impact on corporate
profitability.  This will help us remain sensitive to the performance of the
Fund's corporate bond holdings.  While we intend to maintain our corporate bond
exposure, we may decrease it slightly if the U.S. economy is expected to
experience a dramatic slowdown as a result of the events overseas.  As always,
we will continue our focus on providing investors with current income and
preservation of capital.

/1/  The formula used to calculate the SEC yield is described in detail in the
Fund's statement of additional information and is designed to standardize the
yield calculations so that all mutual fund companies with the same or similar
portfolios use a uniform method to obtain yield figures for their non-money
market advertisements.  SEC yields include the actual amount of interest earned
adjusted by any gain or loss realized due to the return of principal, less
expenses and the maximum offering price calculated on a 30-day month-end basis.

  The distribution rate is based on the actual distributions made by the Fund.
The distribution rate is calculated by annualizing the Fund's most recent income
dividend and dividing that figure by the applicable current public offering
price.

 Past performance is no guarantee of future results.

The accompanying chart compares the performance of the Stagecoach Short-
Intermediate U.S. Government Income Fund Class A shares since inception with the
Lehman Brothers Treasury Note Index.  The chart assumes a hypothetical $10,000
initial investment in Class A shares, reflects all operating expenses and
assumes the maximum initial sales charge of 3.00%.  The Lehman Brothers Treasury
Note Index is an unmanaged index of U.S. Treasury 2-10 year notes.  The Fund is
a professionally managed mutual fund.  The index presented here does not incur
expenses and is not available directly for investment.  Had this Index incurred
operating expenses, its performance would have been lower.

Average annual returns represent the average annual change in value of an
investment over the indicated periods assuming reinvestment of dividends and
capital gains distributions.  Investment return and principal value of an
investment will fluctuate so that an investor's shares, when redeemed, may be
worth more or less than their original cost.  Figures quoted represent past
performance, which is no guarantee of future results.  The Fund's manager has
voluntarily waived all or a portion of its management fees or assumed
responsibility for other expenses, which reduces operating expenses and
increases total return to shareholders.  Without these reductions the Fund's
returns would have been lower.  There is no guarantee that these reductions will
continue.  For Class A shares, the maximum front-end sales charge is 3.00%.
