                           PROSPECTUS/PROXY STATEMENT
 
                                                                November  , 1997
 
 This Prospectus/Proxy Statement relates to (i) the election of Trustees of the
Sierra Trust Funds (the "Trust"), P. O. Box 5118, Westboro, Massachusetts
01581, and (ii) the proposed merger (the "Merger") of the Short Term Global
Government Fund, a series of the Trust (the "Global Government Fund"), into the
Short Term High Quality Bond Fund, also a series of the Trust (the "High Qual-
ity Bond Fund" and, together with the Global Government Fund, the "Funds"). The
Merger is to be effected through the transfer of all of the assets of the
Global Government Fund to the High Quality Bond Fund in exchange for shares of
beneficial interest of the High Quality Bond Fund (the "Merger Shares") and the
assumption by the High Quality Bond Fund of all of the liabilities of the
Global Government Fund, followed by the distribution of the Merger Shares to
the shareholders of the Global Government Fund in liquidation of the Global
Government Fund. As a result of the proposed transaction, each shareholder of
the Global Government Fund will receive in exchange for his or her Global Gov-
ernment Fund shares a number of High Quality Bond Fund shares of the same class
equal in value at the date of the exchange to the aggregate value of the share-
holder's Global Government Fund shares.
 
 Because shareholders of the Global Government Fund are being asked to approve
a transaction which will result in their receiving shares of the High Quality
Bond Fund, this Proxy Statement also serves as a Prospectus for the Merger
Shares of the High Quality Bond Fund. The High Quality Bond Fund seeks as high
a level of current income
 
 
as is consistent with prudent investment man- agement and stability of princi-
pal. It pursues this objective by investing primarily in high quality short-
term bonds and other debt instruments.
 
 THIS PROSPECTUS/PROXY STATEMENT EXPLAINS CONCISELY WHAT YOU SHOULD KNOW BEFORE
INVESTING IN THE HIGH QUALITY BOND FUND. PLEASE READ IT AND KEEP IT FOR FUTURE
REFERENCE.
 
 This Prospectus/Proxy Statement is accompanied by the current Prospectus of
the Trust dated October  , 1997, as amended or supplemented from time to time
(the "Prospectus").
 
 The following documents have been filed with the Securities and Exchange Com-
mission (the "SEC") and are incorporated into this Prospectus/Proxy Statement
by reference: (i) the Report of Independent Accountants and financial state-
ments in respect of the High Quality Bond Fund included in the Trust's Annual
Report to Shareholders for the year ended June 30, 1997 (the "Annual Report");
(ii) the current Statement of Additional Information of the Trust, dated Octo-
ber  , 1997, as amended or supplemented from time to time (the "SAI"); and
(iii) a Statement of Additional Information dated October    , 1997 relating to
the transaction described in this Prospectus/Proxy Statement (the "Merger
SAI").

formation, or Annual Report referred to in the foregoing paragraph, please call

OVERVIEW OF MERGER
 
PROPOSED TRANSACTION
 
 The transaction described on the first page of this Prospectus/Proxy State-
ment is part of an overall restructuring of the registered investment compa-
nies (the "Composite/Sierra Mutual Funds") advised by Composite Research &
Management Co. ("CRM") and Sierra Investment Advisors Corporation ("Sierra").
CRM, which has been in the business of investment management since 1944, is a
direct subsidiary of Washington Mutual, Inc. ("Washington Mutual"), a finan-
cial services company, and Sierra is an indirect subsidiary of Washington Mu-
tual as a result of the merger, which took place on July 1, 1997, of Sierra's
former indirect parent, Great Western Financial Corporation, with and into a
wholly-owned subsidiary of Washington Mutual (the "Washington Mutual/Great
Western Merger"). The restructuring involves, among other components, several
"mergers" of the Composite/Sierra Mutual Funds with similar investment objec-
tives and policies. The result of the restructuring will be a single, more in-
tegrated mutual fund complex, with broader exchange privileges for sharehold-
ers.
 
 As a result of the proposed transaction, the Global Government Fund will re-
ceive a number of Class A, Class B, Class I and Class S shares of the High
Quality Bond Fund (the "Merger Shares") equal in value to the value of the net
assets of the Global Government Fund being transferred and attributable to the
Class A, Class B, Class I and Class S shares, respectively, of the Global Gov-
ernment Fund. Following the transfer, (i) the High Quality Bond Fund will dis-
tribute to each of its Class A, Class B, Class I and Class S shareholders a
number of full and fractional Class A, Class B, Class I and/or Class S Merger
Shares of the High Quality Bond Fund equal in value to the aggregate value of
the shareholder's Class A, Class B, Class I and/or Class S Global Government
Fund shares, as the case may be, and (ii) the Global Government Fund will be
liquidated.
 
 The Class A, Class B, Class I and Class S shares of the High Quality Bond
Fund have substantially identical characteristics to the corresponding classes
of the respective Global Government Fund. Class A shares are generally sold
subject to a front-end sales load and are subject to a distribution fee at an
annual rate of 0.25% of average daily net assets attributable to Class A
shares. Class A shares are generally not subject to a contingent deferred
sales charge (a "CDSC"), except in the case of certain purchases of Class A
shares without a sales load which are redeemed within two years after pur-
chase. Class B shares are sold at net asset value, without an initial sales
charge but subject to a CDSC at declining rates if redeemed within four years
of purchase. Class S shares are sold at net asset value, without a sales
charge but subject to a CDSC at declining rates if redeemed within six years
of purchase. Class B and Class S shares are subject to servicing and distribu-
tion fees at an aggregate annual rate of 1.00% of assets attributable to Class
B or Class S shares and convert automatically to Class A shares approximately
eight years after purchase. Class I shares are sold at net asset value, with-
out an initial sales charge or CDSC, are not subject to servicing or distribu-
tion fees and do not have a conversion feature. No sales charge will be
charged to Global Government Fund shareholders on the issuance of the Merger
Shares, and no CDSC will be charged to Global Government Fund shareholders on
the exchange of their Global Government Fund shares for the Merger Shares. The
Merger Shares will be subject to a CDSC on redemption to the same extent that
the Global Government Fund shares exchanged were so subject. For the purposes
of computing the CDSC, if any, payable on redemption of Class A, Class B and
Class S Merger Shares, and determining the conversion date of Class B and
Class S Merger Shares to Class A shares, the Merger Shares will be treated as
having been purchased as of the date that, and for the price at which, the
Global Government Fund shares exchanged for such Merger Shares were originally
purchased.

 The Trustees unanimously recommend that shareholders of the Global Government
Fund approve the Merger because it offers shareholders the opportunity to pur-
sue a similar investment objectives in a larger fund, which should offer op-
portunities for greater diversification of risk and economies of scale. See
"Operating Expenses" below and "Background and Reasons for the Proposed Merg-
er."
 
OPERATING EXPENSES
 
 The aggregate operating expenses borne by each of the Funds, which have been
reduced by Sierra's voluntary waiver of management fees and reimbursement of
expenses, are expected to be higher after January 1, 1998 because the volun-
tary waiver/reimbursement with respect to the Global Government Fund is ex-
pected to be terminated and the voluntary waiver/reimbursement with respect to
the High Quality Bond Fund is expected to be reduced. However, as the follow-
ing table shows, the currently approved contractual management fee rate for
the High Quality Bond Fund is lower than the currently approved contractual
management fee rate for the Global Government Fund. Accordingly, and as a re-
sult of expected eco-
nomies of scale, it is expected that aggregate operating expenses of the High
Quality Bond Fund will be lower than the aggregate operating expenses cur-
rently borne by the Global Government Fund. There can be no assurance that the
Merger will result in expense savings for shareholders. This table summarizes,
for Class A, Class B, Class I and Class S shares, expenses, in each case, ad-
justed to reflect the reduction or elimination of the voluntary
waiver/reimbursement (i) that the Global Government Fund incurred in its fis-
cal year ended June 30, 1997, (ii) that the High Quality Bond Fund incurred in
its fiscal year ended June 30, 1997, and (iii) that the High Quality Bond Fund
would have incurred in its most recent fiscal year ended June 30, 1997 after
giving effect on a pro forma combined basis to the proposed Merger, as if the
Merger had occurred as of the beginning of such fiscal year. The tables are
provided to help you understand an investor's share of the operating expenses
which each Fund incurs. The examples show the estimated cumulative expenses
attributable to a hypothetical $1,000 investment in the Global Government
Fund, the High Quality Bond Fund and the High Quality Bond Fund on a pro forma
basis, over the specified period.

(1) The initial sales charge is reduced for purchases of $50,000 and over, de-
    creasing to zero for purchases of $1,000,000 and over for each Fund.
(2) Certain investors who purchase Class A shares at net asset value based on
    a purchase amount of $1 million or more may be subject to a 1.0% contin-
    gent deferred sales charge ("CDSC") on redemptions within one year of pur-
    chase or a 0.5% CDSC on redemptions after 1 year but within 2 years of
    purchase. Class A shares purchased through a qualified retirement plan
    may, in certain circumstances, be subject to a CDSC of 1.0% if the shares
    are redeemed within two years of their initial purchase.
(3) A $5.00 fee may be charged for each wire transfer if shares are redeemed
    by wire transfer to a shareholder's pre-authorized designated bank ac-
    count.
(4) Upon written notice to shareholders, the exchange privilege may be modi-
    fied to terminated and/or the Trust may begin imposing a charge of up to
    $5.00 for each exchange.
(5) Reflects the expected termination of, and reduction in voluntary waivers
    of management fees by the adviser for the Global Government and High Qual-
    ity Bond Funds, respectively. Actual management fees for the Global Gov-
    ernment and High Quality Bond Funds were, for the fiscal year ended June
    30, 1997, 0.04% and 0.00%, respectively. In the absence of such voluntary
    waiver, management fees would have been 0.50% for the High Quality Bond
    Fund.
(6) Of the 12b-1 fees for the Class A, Class B and Class S shares, 0.75% rep-
    resents an asset-based sales charge and 0.25% is a service charge. Due to
    the continuous nature of the 12b-1 fee, long-term shareholders of a Fund
    may pay more than the economic equivalent of the maximum front-end sales
    charge otherwise permitted by the Conduct Rules of the National Associa-
    tion of Securities Dealers, Inc. ("NASD").
(7) The "other expenses" set forth in the foregoing table have been restated
    to reflect anticipated "other expenses" (after giving effect to the ex-
    pected reduction in the voluntary waiver/reimbursement for the Global Gov-
    ernment Fund). Actual "other expenses" for the High Quality Bond Fund for
    the year ended June 30, 1996 were 0.57%. The adviser and/or the adminis-
    trator anticipate voluntarily waiving fees and/or bearing expenses of the
    High Quality Bond Fund during the current fiscal year that will result in
    total fund operating expenses as set forth in the foregoing table; they
    are under no obligation to continue to do so. "Other expenses" absent such
    expense reimbursement would have been 0.70% for the High Quality Bond
    Fund.
(8) The total fund operating expenses set forth in the foregoing table have
    been restated to reflect anticipated management fees and other expenses
    (after giving effect to the expected termination of and reduction in vol-
    untary waivers/reimbursements for the Global Government and High Quality
    Bond Funds, respectively). Actual total operating expenses were as fol-
    lows: Global Government Fund, Class A - 0.90%, Class B - 1.65%, Class I -
    0.65% and Class S - 1.65%; High Quality Bond Fund, Class A - 0.82%, Class
    B - 1.57%, Class I - 0.57% and Class S - 1.57%. The adviser and/or the ad-
    ministrator anticipate voluntarily waiving fees and/or bearing expenses
    during the current fiscal year for the High Quality Bond Fund that will
    result in total fund operating expenses as set forth in the foregoing ta-
    ble; they are under no obligation to continue to do so. Total fund operat-
    ing expenses for the High Quality Bond Fund absent such fee
    waivers/expense reimbursements would have been as follows: Class A-1.45%,
    Class B-2.20%, Class I-1.25% and Class S-2.20%.
 
  Waivers of fees and reimbursement of expenses have the effect of increasing
  yield or improving total return for the period when such waivers and reim-
  bursements are in effect. These amounts are not recovered by Sierra or the
  administrator in later years. These fee waivers and agreements to reimburse
  expenses are voluntary and may be discontinued at any time.

FEDERAL INCOME TAX CONSEQUENCES
 
 Based largely on the significant realignment of the Global Government Fund's
portfolio that will occur in connection with the Merger, the Global Government
Fund is expected to recognize gain or loss on the sale of its assets to the
High Quality Bond Fund, and shareholders of the Global Government Fund are ex-
pected to recognize taxable gain or loss on receipt of shares in the High
Quality Bond Fund, equal to the difference between the net asset value of the
High Quality Bond Fund, shares received and the shareholder's tax basis in his
or her Global Government Fund shares. The Merger may therefore cause certain
shareholders to recognize taxable gains. If, as expected, the Merger is a tax-
able transaction, "individuals" (as defined by the Internal Revenue Code) may
use realized capital losses to offset other realized capital gains or to off-
set ordinary income in the current year up to $3,000 and may also carry for-
ward losses indefinitely to offset future realized capital gains, and share-
holders who are not "individuals" may use realized capital losses to offset
realized capital gains in the current year and may also carry forward or carry
back losses to offset future or past realized gains. You should consult your
tax adviser as to your precise tax consequences of the Merger. To receive a
written summary of your investment history call [Sierra Fund Administration
Corporation, 9301 Corbin Avenue, Mail Stop: N0321, Northridge, California
91324].
 
 If, as expected, the Merger is a taxable transaction, the High Quality Bond
Fund's cost basis for each security will be the market value of such security
at the time of the Merger (rather the Global Government Fund's cost basis). As
a result of the Merger, the Global Government Fund's net unrealized losses and
capital loss carryforwards will not be available for use by either Fund. The
Global Government Fund will distribute at the time of the Merger all of the
Global Government Fund's net investment income, which will be taxable income
to shareholders of the Global Government Fund. The Federal income tax
treatment of the Merger is not clear, and the Internal Revenue Service may
take the position that it is a tax-free reorganization.

COMPARISON OF INVESTMENT OBJECTIVES,
POLICIES AND RESTRICTIONS 

 The High Quality Bond Fund has investment objectives that are substantially
similar to those of the Global Government Fund. The investment objectives,
policies and restrictions of the Funds, and certain differences between them,
are summarized below. For a more detailed description of the investment tech-
niques used by the Funds, please see the accompanying Prospectus, SAI and
Merger SAI.

 The total return for the High Quality Bond Fund and the Global Government
Fund is set forth in the chart below. Because of the different management
styles, however, the relative contributions of the two components of total re-
turn (i.e., current income and capital appreciation) varied between the High
Quality Bond Fund and the Global Government Fund. The yield (calculated in ac-
cordance with SEC regulations) of the High Quality Bond Fund was     versus
    for the Global Government Fund during the 30-day period ended     and av-
eraged     and    , respectively, over the 12-month period ended       .

* Performance is for Class A shares of both Funds. Fund performance data is
after all expenses. No competitive performance information is shown for a 10
year period because the Global Government
 
                                       9
<PAGE>
 
Fund did not commence operations until    , 19  . For further information
about the High Yield Fund's performance, see Appendix B.
 
 The Funds have substantially similar investment objectives. The High Quality
Bond Fund is a diversified fund and attempts to provide as high a level of
current income as is consistent with prudent investment management and stabil-
ity of principal whereas the Global Government Fund is a non-diversified fund
and is designed to provide high current income consistent with protection of
principal.
 
 The Global Government Fund seeks to maintain greater price stability than
longer-term bond funds. The Funds seek to maintain a dollar-weighted average
portfolio maturity of three years or less but may hold individual securities
with remaining maturities of more than three years. However, under no circum-
stances will the High Quality Bond Fund have a dollar-weighted average portfo-
lio maturity in excess of five years.
 
 Under normal market conditions, the Global Government Fund will invest at
least 65% of total assets in short-term bonds and money market instruments is-
sued or guaranteed by foreign governments or the U.S. Government or their
agencies, instrumentalities or political subdivisions (including securities
which are majority owned by such government, agency, instrumentality or polit-
ical subdivision) that are rated within the three highest rating categories by
Standard & Poor's ("S&P") or Moody's Investors Service, Inc. ("Moody's") or,
if unrated, are judged to be of comparable quality. These securities may be
denominated in foreign currencies, multinational currency units or the U.S.
dollar and under normal market conditions will be invested in government secu-
rities in at least three different countries, one of which may be the United
States. In the case of the High Quality Bond Fund, at least 65% of total as-
sets will be invested in short-term investment-grade bonds and other fixed-in-
come securities issued by the U.S. Government, corporations and other issuers,
or mortgage-related securities rated in one of the two highest categories by a
nationally recognized statistical rating organization ("NRSRO"). All debt se-
curities purchased by the High Quality Bond Fund will be investment-grade
(rated in one of the four highest categories by a NRSRO) at the time of pur-
chase. See "Risk Factors--Market Risk."
 
 Both the Funds may also invest in: (i) American depository receipts; (ii) se-
curities indexed to foreign currency exchange rates; (iii) floating rate, in-
verse floating rate and variable rate obligations, including participation in-
terests therein; (iv) bank obligations, which include certificates of deposit,
time deposits and bankers' acceptances of U.S. commercial banks or savings and
loan institutions with assets of at least $500 million as of the end of the
most recent fiscal year; (v) mortgage-backed and government stripped mortgage-
backed securities; (vi) repurchase agreements; and (vii) lease obligation
bonds. Each Fund may also borrow up to 30% of total assets for temporary emer-
gency purposes, purchase securities on a "when-issued" or "delayed-delivery"
basis, invest up to 10% of assets in securities of unaffiliated mutual funds
and lend securities up to 20% of the Fund's total assets.
 
 The Funds may utilize various other investment strategies involving deriva-
tives, including exchange-listed and over-the-counter put and call options on
securities, foreign currencies, equity and fixed-income indices and other fi-
nancial instruments, financial futures contracts and options thereon, currency
forward transactions, and interest rate transactions such as swaps, caps,
floors and collars to hedge various market risks, to manage the effective ma-
turity or duration of fixed-income securities, or to seek potentially higher
returns. The Funds may write covered put and call options on securities but
neither Fund will use more than 10% of assets to purchase put options or more
than 10% of assets to purchase call options, will not write put options with
respect to more than 50% of total assets, and will not enter into deriva-
 
                                      10
<PAGE>
 
tive transactions that are not "covered" or entered into for "bona fide hedg-
ing" purposes that are in the aggregate principal amount in excess of 25% of
its net assets. In addition, neither Fund may enter into any futures or op-
tions contracts for which aggregate initial margin deposits and premiums paid
for unexpired options entered into for purposes other than bona fide hedging
exceed 5% of the fair market value of the Fund's assets.
 
 The Global Government Fund may also invest: (i) up to 10% of its assets in
securities rated at the time of purchase below investment-grade (below BBB by
S&P's or Baa by Moody's) and unrated securities of comparable quality; (ii) in
non-government foreign and domestic securities, including debt securities is-
sued or guaranteed by supranational organizations, corporate debt securities,
and bank or bank holding company obligations such as certificates of deposit,
bankers' acceptances and time deposits; and (iv) up to 10% of total assets in
asset-backed securities. See Risk "Factors--Lower-rated Securities."
 
 The High Quality Bond Fund may also invest: (i) up to 10% of assets in for-
eign fixed-income securities including non-U.S. dollar denominated debt; (ii)
in high-quality, short-term obligations with a maturity of 12 months or less,
such as commercial paper issued by domestic and foreign corporations, bankers'
acceptances issued by domestic and foreign banks, certificates of deposit and
demand and time deposits of domestic and foreign banks and savings and loan
associations; (iii) obligations issued or guaranteed by domestic or foreign
governments or their agencies or instrumentalities; (iv) high-grade corporate
debt obligations, such as bonds, debentures, notes, equipment lease and truck
certificates; (v) collateralized mortgage obligations; (vi) up to 25% of total
assets in asset-backed securities; and (vii) in certain illiquid investments
such as privately placed obligations including restricted securities and may
borrow money or enter into reverse repurchase agreements or dollar roll trans-
actions in the aggregate up to 33 1/3% of total assets (but currently intends
to limit such activity to 10% of total assets). See "Risk Factors--Prepayment
Risk," "--Repurchase Agreements," and "--Reverse Repurchase Agreements and
Borrowings."
 
 In addition to the investment restrictions described above, the Global Gov-
ernment Fund may not invest in dollar rolls and will not purchase any addi-
tional securities whenever borrowings, including reverse repurchase agree-
ments, exceed 5% of total assets.
 
 In addition to the investment restrictions described above, the High Quality
Bond Fund may not engage in short sales or maintain short positions or invest
in non-investment-grade securities (rated lower than BBB by S&P or Baa by
Moody's).
 
 Adam M. Greshin, Product Leader for Scudder's global and international fixed-
income investing, is primarily responsible for the management of the Global
Government Fund. The day-to-day management of the High Quality Bond Fund's
portfolio has been the responsibility of Thomas M. Poor, Managing Director of
Scudder.
 
 The Trustees of the Sierra Trust for the High Quality Bond Fund have approved
a new Advisory Agreement (the "CRM Advisory Agreement") with CRM whereby CRM
will replace Scudder, Stevens & Clark, Inc. ("Scudder") as the sub-advisor of
the High Quality Bond Fund as part of the overall restructuring explained
above. The CRM Advisory Agreement will be voted upon at the meeting of the
High Quality Bond Fund's shareholders to be held on December    , 1997.
 
 As discussed above, it is expected that, subject to the approval of share-
holders of the High Quality Bond Fund, CRM will, at or prior to the time of
the Merger, become the investment adviser to the High Quality Bond Fund, re-
placing Sierra Advisors, and will thereafter be responsible for management of
the Sierra High Quality Bond Fund. CRM would manage the Fund itself, without
the
 
                                      11
<PAGE>
 
use of a subadviser.    ,     of CRM, would be primarily responsible for the
management of the Fund. [CRM does not intend to effect any changes to the in-
vestment practices followed by Scudder with respect to this Fund, as outlined
above.] The approval of CRM as adviser to the High Quality Bond Fund is not a
condition to the Merger. Thus, depending on whether shareholders at the High
Quality Bond Fund approve the proposed advisory arrangement with CRM, the day
to day portfolio manager of the High Quality Bond Fund following the Merger
may be provided either by CRM or by Scudder.
 
COMPARISON OF DISTRIBUTION POLICIES AND PURCHASE, EXCHANGE AND REDEMPTION
PROCEDURES
 
 Both Funds declare dividends daily and pay them monthly. Both the Funds dis-
tribute any net realized capital gains annually.
 
 The Funds have the same procedures for purchasing shares. The Funds offer
four classes of shares, Classes A, B, I and S. Class I shares are sold exclu-
sively to the various investment portfolios of Sierra Asset Management Portfo-
lios (the "SAM Portfolios"), a series investment company managed by Sierra In-
vestment Services Corporation ("Sierra Services"), and are not available for
direct purchase by investors. Class S shares are sold only to investors who
select or have previously selected the Sierra Asset Management service offered
by Sierra Services. Class A and Class B shares (and, for eligible investors,
Class S shares) of both Funds may be purchased at their net asset value next
determined after receipt of a properly completed purchase order, plus applica-
ble sales charges in the case of Class A shares, from Sierra Services, the
Principal underwriter of the Funds as well as the other mutual funds in the
Sierra Funds family. In addition, shares of the Funds may be purchased through
other broker-dealers that have dealer agreements with Sierra Services.
 
 Shares of the Funds can be exchanged for shares of the same class of any fund
advised by CRM (other than funds serving as underlying funding vehicles for
variable insurance contracts), or of any other fund offered by the Trust, SAM
Portfolios or Sierra Prime Income Fund ("SPIF"), a closed-end investment com-
pany advised by Sierra. In addition, Class B shares of the Funds can, under
certain circumstances, be exchanged for Class S shares of the same Fund or any
other Fund offered by the Trust or (in the case of exchanges from the High
Quality Bond Fund) advised by CRM, and Class S shares of the Funds can be ex-
changed, under certain circumstances, for Class B shares of the SAM Portfo-
lios.
 
 The availability of the exchange privilege with respect to shares of SPIF is
subject to the availability of shares of SPIF for exchange purposes as stated
in the prospectus and statement of additional information ("SAI") of SPIF. Al-
so, although shares of SPIF may be exchanged for shares of the Funds, such ex-
changes of SPIF shares for shares of the Funds are only permitted approxi-
mately once every calendar quarter so long as SPIF makes a repurchase offer
for its shares in such quarter and so long as the SPIF repurchase offer is
sufficiently large to include the SPIF shares tendered for exchange. See the
prospectus and SAI of SPIF for additional information regarding the exchange
privilege applicable to SPIF shares and the availability of such exchange
privilege.
 
 Shares of the Funds may be redeemed at their net asset value next determined
after receipt of the redemption request, less any applicable CDSC, on any day
the New York Stock Exchange is open. Shares can be redeemed through Sierra
Services, or, through the dealer through which the shares were purchased, by
mail, by telephone or by other means of wire communication.
 
 See the accompanying Prospectus for further information.

RISK FACTORS
 
 Certain risks associated with an investment in the High Quality Bond Fund are
summarized below. Because the High Quality Bond Fund shares similar investment
objectives and policies with the Global Government Fund and because both Funds
share certain policies described more fully above under "Overview of Merger--
Comparison of Investment Objectives, Policies and Restrictions," many of the
risks of an investment in the High Quality Bond Fund are substantially similar
to the risks of an investment in the Global Government Fund. A more detailed
description of certain of the risks associated with an investment in the High
Quality Bond Fund may be found in the Prospectus under the caption "The Funds'
Investments and Risk Considerations" and in the SAI under the same caption.

Bond Funds vary from time to time in response to a wide variety of market fac-
tors. Consequently, the net asset value per share of the High Quality Bond
Fund will vary so that an investor's shares, when redeemed, may be worth more
or less than the amount invested.
 
 INTEREST RATE RISK. The Funds share similar risks for investment in fixed in-
come securities, including U.S. Government securities. U.S. Government securi-
ties are considered among the safest of fixed-income investments, but their
values, like those of other debt securities, will fluctuate with changes in
interest rates. Thus, a decrease in interest rates will generally result an
increase in the value of the High Quality Bond Fund's holdings of U.S. Govern-
ment securities. Conversely, during periods of rising interest rates, the
value of the High Quality Bond Fund's holdings of fixed income securities will
generally decline.
 
 PREPAYMENT RISK. The Funds share similar risks for investment in mortgage-
backed or asset-backed securities. The High Quality Bond Fund may invest in
mortgage-backed securities. Prepayment on mortgage-backed or asset-backed se-
curities may require reinvestment of principal under less attractive terms.
Prepayments may also significantly shorten the effective maturities of these
securities, especially during periods of declining interest rates. Conversely,
during periods of rising interest rates, a reduction in prepayments may in-
crease the effective maturities of these securities. Prepayments may cause
losses in securities purchased at a premium. Prepayments could result in
losses on stripped mortgage-backed or asset-backed securities. The yield-to-
maturity on an interest-only class of stripped mortgage-backed or asset-backed
securities is extremely sensitive not only to changes in prevailing interest
rates but also to the rate of principal payments (including prepayments) on
the underlying assets. Because of the foregoing characteristics, mortgage-
backed securities may be more volatile than other fixed income securities.
 
 REPURCHASE AGREEMENTS. Investing in repurchase agreements subjects the High
Quality Bond Fund, like the Global Government Fund, to the risk that the de-
fault or bankruptcy of the other party to the repurchase agreement could sub-
ject the fund to expenses, delays and risk of loss on the securities subject
thereto.
 
 REVERSE REPURCHASE AGREEMENTS AND BORROWINGS. The High Quality Bond Fund may
invest in reverse repurchase agreements in the aggregate up to 33 1/3% of its
total assets but currently intends to limit such activity to 10% of total as-
sets. Reverse repurchase agreements and borrowings subject the High Quality
Bond Fund to the risk that changes in the value of a Fund's portfolio securi-
ties may amplify changes in the Fund's net asset value per share and also may
cause the Fund to liquidate portfolio positions when it would not be advanta-
geous to do so.
 
 ILLIQUID SECURITIES. The Funds share similar risks for investment in illiquid
securities--specifically, higher transaction costs.
 
 INVESTMENT IN FOREIGN SECURITIES. Each of the Funds may invest in foreign se-
curities, including debt securities issued or guaranteed by supranational or-
ganizations. Investment in foreign securi-
 
                                      13
<PAGE>
 
ties involves the risk of potentially reduced domestic marketability of such
securities, the lower reserve requirements generally mandated for overseas
banking operations, the possible impact of interruptions in the flow of inter-
national currency transactions, potential political and social instability or
expropriation, imposition of foreign taxes, less government supervision of is-
suers, difficulty in enforcing contractual obligations and lack of uniform ac-
counting standards.
 
 LENDING OF PORTFOLIO SECURITIES. The Funds may incur similar risks from lend-
ing their securities. As with other extensions of credit, there are risks of
delay in recovery or even loss of rights in the collateral should the borrower
of the securities fail financially.
 
 DERIVATIVE INSTRUMENTS. The High Quality Bond Fund may enter into options and
futures contracts for hedging purposes or as a part of their investment strat-
egies and may engage in swap agreements. Use of derivative instruments may in-
volve certain costs and risks, including the risk that the Fund could not
close out a position when it would be most advantageous to do so due to an il-
liquid market, the risk of an imperfect correlation between the value of the
securities being hedged and the value of the particular derivative instrument,
the risk of bankruptcy or default of counterparties and the risk that unex-
pected changes in interest rates or other market movements may adversely af-
fect the value of the Fund's investments in particular derivative instruments.

SPECIAL MEETING OF SHAREHOLDERS

 This Prospectus/Proxy Statement is furnished in connection with a Special
Meeting of Global Government Fund Shareholders to be held on December  , 1997
or at such later time made necessary by adjournment (the "Meeting") and the
solicitation of proxies by and on behalf of the Trustees of the Trust for use
at the Meeting. The Meeting is being held to consider the election of Trustees
of the Trust and the proposed Merger of the Global Government Fund and the
High Quality Bond Fund by the transfer of all of the Global Government Fund's
assets and liabilities to the High Quality Bond Fund. This Prospectus/Proxy
Statement and the enclosed form of proxy are being mailed to shareholders on
or about November  , 1997.
 
 The Trustees of the Trust know of no matters other than those set forth
herein to be brought before the Meeting. If, however, any other matters prop-
erly come before the Meeting, it is the Trustees' intention that proxies will
be voted on such matters in accordance with the judgment of the persons named
in the enclosed form of proxy.

- -------------------------------------------------------------------------------
PROPOSAL 1:
ELECTION OF TRUSTEES

 At the Meeting, it is proposed that thirteen Trustees of the Trust be elected
to hold office until their successors are duly elected and qualified. The per-
sons named in the accompanying proxy intend, in the absence of contrary in-
structions, to vote all proxies on behalf of the shareholders for the election
of David E. Anderson, Wayne L. Attwood, M.D. Arthur H. Bernstein, Esq.
Kristianne Blake, Edmond R. Davis, Esq. John W. English, Anne V. Farrell,
Michael K. Murphy, Alfred E. Osborne, Jr. William G. Papesh, Daniel L.
Pavelich, Jay Rockey and Richard C. Yancey (each a "Nominee" and collectively,
the "Nominees"). Messrs. Anderson, Bernstein, Davis, English and Osborne are
currently members of the Trust's Board of Trustees. Messrs. Atwood, Murphy,
Papesh, Pavelich, Rockey and Yancey and Mses. Blake and Farrell are all direc-
tors of the mutual funds advised by CRM (the "Composite Funds"), but have not
previously served on the Trust's Board of Trustees.

 Shareholders of the Global Government Fund, along with the shareholders of
each other series of the Trust, are entitled to vote in the election of the
Trust's Trustees. If the proposed Merger by and between Global Government Fund
and High Quality Bond Fund is consummated, the Global Government's separate
existence would be terminated and its shareholders would become shareholders
of the High Quality Bond Fund, which is also a series of the Trust, and would
be governed by the same Board of Trustees.
 
 The proposal to elect the Board of Trustees is being presented for share-
holder approval pursuant to requirements of the Investment Company Act of 1940
(the "1940 Act"). Under the 1940 Act, Trustees may not fill vacancies unless
at least two-thirds of the Trustees holding office after such vacancies are
filled have been elected by the shareholders. Approval of this proposal will
result in a combined Board of Trustees consisting of the current Trustees and
the trustees of the Composite Funds. The proposal, if approved will provide
the Board with operating flexibility by making it possible for the Board of
Trustees to fill vacancies that may occur in the future.
 
 Each of the Nominees has consented to being named in this Prospectus/Proxy
Statement and to serving as a Trustee if elected. The Trust knows of no reason
why any Nominee would be unable or unwilling to serve if elected.
 
 The Trust is organized as a business trust under the laws of the Commonwealth
of Massachusetts. Under Massachusetts law, the Trust is not required to hold
annual meetings. The Trust has availed itself of this provision and achieves
cost savings by eliminating printing costs, mailing charges and other expenses
involved in routine annual meetings. Because the Trust does not hold regular
annual shareholder meetings, each Nominee, if elected, will hold office until
his or her successor is elected and qualified.
 
 Even with the elimination of routine annual meetings, the Board of Trustees
may call special meetings of shareholders for action by shareholder vote as
may be required by the 1940 Act, or as required or permitted by the Trust's
Master Trust Agreement. Shareholder meetings will be held, in compliance with
the 1940 Act, to elect Trustees under certain circumstances. Shareholder meet-
ings may also be held by the Trust for other purposes, including to approve
investment policy changes, a new investment advisory agreement or other mat-
ters requiring shareholder action under the 1940 Act.
 
 A meeting may also be called by shareholders holding at least 10% of the
shares entitled to vote at the meeting for the purpose of voting upon the re-
moval of Trustees, in which case shareholders may receive assistance in commu-
nicating with other shareholders as if the provisions contained in Section
16(c) of the 1940 Act applied.
 
INFORMATION REGARDING NOMINEES
 
 The following information is provided for each Nominee. It includes his or
her name, position with the Trust, if so held, tenure in office, trustee posi-
tions principal occupations or employment during the past five years,
directorships/trusteeships with other companies which file reports periodi-
cally with the SEC, number of trustee positions with the registered investment
companies which hold themselves out to investors as related companies for pur-
poses of investment and investor services to which Sierra or an affiliated
person of Sierra provides investment advisory or administration services (col-
lectively, the "Fund Complex"), number of shares of the Funds of the Trust be
neficially owned and percentage of shares of the funds of the Trust benefi-
cially owned. As of July 1, 1997, the Nominees as a group beneficially owned
an aggregate of less than 1% of the shares of each fund of the Trust and the
Trustees and officers of the Trust as a group beneficially owned an aggregate
of less than 1% of the shares of each fund of the Trust.

COMPENSATION OF TRUSTEES
 Each Trustee who is not an "interested person" receives an aggregate annual
fee (plus reimbursement for reasonable out-of-pocket expenses incurred in con-
nection with his or her attendance at Board and committee meetings) from the
Funds and all of the funds in the Fund Complex for which he or she serves. The
Trust pays each Trustee who is not a director, officer or employee of Washing-
ton Mutual, Inc., Sierra Investment Services Corporation, Sierra Investment
Advisors Corporation, the sub-advisors to the Trust or First Data Investor
Services Group, Inc., or any of their affiliates, $7,500 per annum plus $1,500
per board meeting attended, $1,000 per Audit and/or Nominating Committee meet-
ing attended and reimbursement for travel and out-of-pocket expenses. Since
December 1996, Mr. Bernstein, Chairman of the Trust, has received one and a
half times the Trustee's compensation described above. The Chairman of the Au-
dit Committee receives $1,500 per Audit Committee meeting attended. Officers
of the Trust receive no direct remuneration in such capacity from the Trust.
Officers of the Trust who are employees of Sierra or its affiliates may be
considered to have received remuneration indirectly.
 
 Pursuant to an exemptive order granted by the SEC, the Trust's eligible
Trustees may participate in a deferred compensation plan (the "Plan") which
may be terminated at any time. Under the Plan, Trustees may elect to defer re-
ceipt of all or a portion of their fees which, in accordance with the Plan,
are invested in mutual fund shares. Upon termination of the Plan, Trustees
that have deferred accounts under the Plan will be paid benefits no later than
the time the payments would otherwise have been made without regard to such
termination. All benefits provided under these plans are funded and any pay-
ments to plan participants are paid solely out of the Trust's assets.
 
 The aggregate compensation payable by the Trust to each of the Trust's Trust-
ees serving during the fiscal year ended June 30, 1997 is set forth in the
compensation table below. The aggregate compensation payable to such Trustees
during the fiscal year ended June 30, 1997, by the Fund Complex is also set
forth in the compensation table below.

MEETINGS AND COMMITTEES OF THE BOARD
OF TRUSTEES
 
 There were fifteen meetings of the Board of Trustees held during the fiscal
year ended June 30, 1997. In such fiscal year, all Trustees attended at least
75% of the meetings of the Board of Trustees.
 
 The Board of Trustees has an Audit Committee. The Audit Committee makes rec-
ommendations to the full Board of Trustees with respect to the engagement of
independent accountants and reviews, with the independent accountants, the re-
sults of the audit engagement and matters having a material effect on the
Fund's financial operations. The members of the Audit Committee during the
fiscal year ended June 30, 1997, were Messrs. Bernstein (Chairman), Anderson,
Davis, English and Osborne, each of whom is not an "interested person" within
the meaning of the 1940 Act. The Audit Committee met once during the fiscal
year ended June 30, 1997 and all members attended the meeting. The Chairman of
the Audit Committee receives $1,500 for each Audit Committee meeting attended.
 
 The Board of Trustees has a Nominating Committee. The Nominating Committee
makes recommendations to the full Board of Trustees with respect to candidates
for the Board of Trustees. The members of the Nominating Committee during the
fiscal year ended June 30, 1997, were Messrs. Cerini (Mr. Cerini resigned as a
Trustee of the Trust effective May 29, 1997), Anderson, Bernstein, Davis, Os-
borne and English, each of whom, with the exception of Mr. Cerini, is not an
"interested person" within the meaning of the 1940 Act. The Nominating Commit-
tee did not meet during the fiscal year ended June 30, 1997 and all members
attended the meeting held on October 27 and 28, 1997.
 
BOARD APPROVAL OF THE ELECTION OF TRUSTEES
 
 At a meeting of the Board of Trustees held October 27 and 28, 1997, the Board
of Trustees unanimously recommended that shareholders vote FOR each of the
Nominees for Trustee named herein. In recommending that shareholders elect the
Nominees as Trustees of the Trust, the Board considered the Nominees' experi-
ence and qualifications. In particular, each of the Nominees who has not pre-
viously served on the Board of Trustees of the Trust has previous experience
serving on the Board of Directors of the various Composite funds.
 
SHAREHOLDER APPROVAL OF THE ELECTION OF TRUSTEES
 
 The Election of the Trustees requires the affirmative vote of a plurality of
all votes cast at the Meeting, provided that a majority of the shares entitled
to vote are present in person or by Proxy at the Meeting. If your shares are
represented at the meeting but you give no voting instructions, your shares
will be voted FOR all Nominees named herein. If the Nominees are not approved
by shareholders of the Trust, the Board of Trustees will consider alternative
nominations.
 
 THE BOARD OF TRUSTEES OF THE TRUST RECOMMENDS THAT THE SHAREHOLDERS OF THE
GLOBAL GOVERNMENT FUND VOTE FOR THE ELECTION OF THE NOMINEES AS TRUSTEES OF
THE TRUST.
- -------------------------------------------------------------------------------
PROPOSAL 2:
 
APPROVAL OR DISAPPROVAL OF AGREEMENT
AND PLAN OF REORGANIZATION

 The shareholders of the Global Government Fund are being asked to approve or
disapprove a Merger between the Global Government Fund and the High Quality
Bond Fund. The Merger is proposed to take place pursuant to an Agreement and
Plan of Reorganization between the Global Government Fund and the High Quality
Bond Fund, [dated as of October   , 1997] (the "Agree-
 
                                      19
<PAGE>
 
ment"), the form of which is attached to this Prospectus/Proxy Statement as
Appendix A.
 
 The Agreement provides, among other things, for the transfer of all of the
assets of the Global Government Fund to the High Quality Bond Fund in exchange
for (i) the assumption by the High Quality Bond Fund of all of the liabilities
of the Global Government Fund and (ii) the issuance to the Global Government
Fund of the Class A, Class B, Class I and Class S Merger Shares, the number of
which will be calculated based on the value of the net assets attributable to
the Class A, Class B, Class I and Class S shares, respectively, of the Global
Government Fund acquired by the High Quality Bond Fund and the net asset value
per Class A, Class B, Class I and Class S share of the High Quality Bond Fund,
all as more fully described below under "Information About the Merger."
 
 After receipt of the Merger Shares, the Global Government Fund will cause the
Class A Merger Shares to be distributed to its Class A shareholders, the Class
B Merger Shares to be distributed to its Class B shareholders, the Class I
Merger Shares to be distributed to its Class I shareholders and the Class S
Merger Shares to be distributed to its Class S shareholders, in complete liq-
uidation of the Global Government Fund. Each shareholder of the Global Govern-
ment Fund will receive a number of full and fractional Class A, Class B, Class
I or Class S Merger Shares equal in value at the date of the exchange to the
aggregate value of the shareholder's Class A, Class B, Class I or Class S
Global Government Fund shares, as the case may be.
 
 TRUSTEES' RECOMMENDATIONS. THE TRUSTEES OF THE TRUST HAVE VOTED UNANIMOUSLY
TO APPROVE THE PROPOSED MERGER BY AND BETWEEN THE GLOBAL GOVERNMENT FUND AND
HIGH QUALITY BOND FUND AND TO RECOMMEND THAT SHAREHOLDERS OF THE GLOBAL GOV-
ERNMENT FUND ALSO APPROVE THE MERGER FOR SUCH FUND.
 
 REQUIRED SHAREHOLDER VOTE. Approval of the proposed Merger will require the
affirmative vote of the lesser of (A) 67% or more of the Class A, Class B,
Class I and Class S shares of the Global Government Fund present or repre-
sented at the Meeting, voting together as a single class, if the holders of
more than 50% of the outstanding Class A, Class B, Class I and Class S shares
are present or represented by proxy at the Meeting, or (B) more than 50% of
the outstanding Class A, Class B, Class I and Class S shares of the Global
Government Fund, voting together as a single class.
 
 A shareholder of the Global Government Fund objecting to the proposed Merger
is not entitled under either Massachusetts law or the Trust's Master Trust
Agreement (the "Sierra Declaration of Trust") to demand payment for or an ap-
praisal of his or her Global Government Fund shares if the Merger is consum-
mated over his or her objection. Shareholders may, however, redeem their
shares at any time prior to the Merger, and if the Merger is consummated,
shareholders will still be free at any time to redeem their Merger Shares, in
each case for cash at net asset value at the time of such redemption, less any
applicable CDSC, or to exchange their Merger Shares for shares of the same
class of any fund advised by CRM (other than funds serving as underlying fund-
ing vehicles for variable insurance contracts) certain other funds offered by
the Trust, SAM Portfolios or SPIF, at net asset value at the time of such ex-
change.
 
BACKGROUND AND REASONS FOR THE PROPOSED MERGERS
 
 The Trustees of the Global Government Fund, including the Trustees who are
not "interested persons" of the Trust (the "Independent Trustees"), have de-
termined that the Merger would be in the best interests of the Global Govern-
ment Fund, and that the interests of the Global Government Fund's shareholders
would not be diluted as a result of effecting the Merger. At a meeting held on
October 27 and 28, 1997, the Trustees [unanimously] approved the proposed
Merger and recommended its approval by shareholders. Before reaching its con-
clusions, the Trust's Board of Trustees conducted an extensive "due diligence"
 
                                      20
<PAGE>
 
review. Among other things, the Board received reports from counsel and ex-
perts hired to evaluate the Merger. Furthermore, the Trustees took into ac-
count the capital loss carry-forwards and the unrealized capital appreciation
in the Funds, in each case as a percentage of the Fund's total net assets.
Those percentages as of June 30, 1997 were as follows:

</TABLE>
 
 The principal reasons why the Trustees are recommending the Merger, and the
overall restructuring of the Composite/Sierra Mutual Funds as discussed on
page 4, are as follows:
 
  (i) ECONOMIES OF SCALE AT FUND LEVEL. The Trustees have determined that it
 is in the best interests of the Global Government Fund's shareholders to com-
 bine the Global Government Fund with the High Quality Bond Fund in order to
 increase the asset base over which the Global Government Fund's expenses will
 be spread. The increased asset base is expected to result in aggregate oper-
 ating expenses (exclusive of management fees) that, absent any waiver of man-
 agement fees or reimbursement of expenses, would be lower than those cur-
 rently borne by the Global Government Fund. In addition, as described more
 fully in the overview under "Operating Expenses," the currently approved con-
 tractual management fee rate for the High Quality Bond Fund is lower than the
 currently approved contractual management fee rate for the Global Government
 Fund, although the reduction of Sierra's voluntary waiver/ reimbursement will
 result in aggregate operating expenses for the High Quality Bond Fund that
 are higher than those currently borne by the Global Government Fund.
 
  (ii) EXPERIENCED LEADERSHIP AND A HERITAGE SINCE 1939. CRM (the proposed new
 investment adviser to the High Quality Bond Fund subsequent to the overall
 restructuring) has extensive mutual fund experience, with the four senior ex-
 ecutives having an average of over 23 years in the financial services indus-
 try. Washington Mutual, Inc. was a pioneer in bank distribution of mutual
 funds when it acquired Murphey Favre, Inc. (the predecessor to Washington Mu-
 tual Financial Services, Inc.) in 1982. [CRM has served as investment adviser
 to mutual funds since 1939.]
 
  (iii) APPROPRIATE INVESTMENT OBJECTIVES, DIVERSIFICATION, ETC. The invest-
 ment objectives, policies and restrictions of the High Quality Bond Fund are
 substantially similar to those of the Global Government Fund, and the Trust-
 ees believe that an investment in shares of the High Quality Bond Fund (whose
 portfolio will have been combined with that of the Global Government Fund)
 will provide shareholders with an investment opportunity comparable to that
 currently afforded by the Global Government Fund, with the potential for re-
 duced investment risk because of the opportunities for additional diversifi-
 cation of portfolio investments through increased Fund assets.
 
  (iv) LARGER, MORE INTEGRATED FUND COMPLEX. The Merger will allow the share-
 holders of the Global Government Fund to enjoy the benefits of integration in
 the same manner that the overall restructuring of the Composite/Sierra Mutual
 Funds should reduce the possibility of confusion for shareholders between
 funds within the same family with similar names and/or in-
 
                                      21
<PAGE>
 
 vestment objectives. It will also give shareholders broader exchange privi-
 leges among funds subsequent to the overall restructuring.
 
INFORMATION ABOUT THE MERGER
 
 AGREEMENT AND PLAN OF REORGANIZATION. The proposed Agreement and Plan of Re-
organization provides that the High Quality Bond Fund will acquire all of the
assets of the Global Government Fund in exchange for the assumption by the
High Quality Bond Fund of all of the liabilities of the Global Government Fund
and for the issuance of the Class A, Class B, Class I and Class S Merger
Shares, all as of the Exchange Date (defined in each Agreement to be December
[31], 1997 or such other date as may be agreed upon by the Fund). The follow-
ing discussion of the Agreement is qualified in its entirety by the full text
of the Agreement, the form of which is attached as Appendix A to this
Prospectus/Proxy Statement.
 
 The Global Government Fund will sell all of its assets to the High Quality
Bond Fund, and, in exchange, the High Quality Bond Fund will assume all of the
liabilities of the Global Government Fund and deliver to the Global Government
Fund (i) a number of full and fractional Class A Merger Shares having an ag-
gregate net asset value equal to the value of the assets of the Global Govern-
ment Fund attributable to its Class A shares, less the value of the liabili-
ties of the Global Government Fund assumed by the High Quality Bond Fund at-
tributable to the Class A shares of the Global Government Fund, (ii) a number
of full and fractional Class B Merger Shares having an aggregate net asset
value equal to the value of assets of the Global Government Fund attributable
to its Class B shares, less the value of the liabilities of the Global Govern-
ment Fund assumed by the High Quality Bond Fund attributable to the Class B
shares of the Global Government Fund, (iii) a number of full and factional
Class I Merger Shares having an aggregate net asset value equal to the value
of the assets of the Global Government Fund attributable to its Class I
shares, less the value of the liabilities of the Global Government Fund as-
sumed by the High Quality Bond Fund attributable to the Class I shares of the
Global Government Fund and (iv) a number of full and fractional Class S Merger
Shares having an aggregate net asset value equal to the value of assets of the
Global Government Fund attributable to its Class S shares, less the value of
the liabilities of the Global Government Fund assumed by the High Quality Bond
Fund attributable to the Class S shares of the Global Government Fund.
 
 Immediately following the Exchange Date, the Global Government Fund will dis-
tribute pro rata to its shareholders of record as of the close of business on
the Exchange Date the full and fractional Merger Shares received by the Global
Government Fund, with Class A Merger Shares being distributed to holders of
Class A shares of the Global Government Fund, Class B Merger Shares being dis-
tributed to holders of Class B shares of the Global Government Fund, Class I
Merger Shares being distributed to holders of Class I shares of the Global
Government Fund and Class S Merger Shares being distributed to holders of
Class S shares of the Global Government Fund. As a result of the proposed
transaction, each holder of Class A, Class B, Class I and Class S shares of
the Global Government Fund will receive a number of Class A, Class B, Class I
and Class S Merger Shares equal in aggregate value at the Exchange Date to the
value of the Class A, Class B, Class I and Class S shares, respectively, of
the Global Government Fund held by the shareholder. This distribution will be
accomplished by the establishment of accounts on the share records of the High
Quality Bond Fund in the names of the Global Government Fund shareholders,
each account representing the respective number of full and fractional Class
A, Class B, Class I and Class S Merger Shares
 
                                      22

due such shareholder. New certificates for Merger Shares will not be issued.
 
 The consummation of the Merger is subject to the conditions set forth in the
Agreement, any of which may be waived. The Agreement may be terminated and the
Merger abandoned at any time, before or after approval by the shareholders of
the Global Government Fund, prior to the Exchange Date, by mutual consent of
the Global Government Fund and the High Quality Bond Fund or, if any condition
set forth in the Agreement has not been fulfilled and has not been waived by
the party entitled to its benefits, by such party.
 
 All legal and accounting fees and expenses, printing and other fees and ex-
penses (other than portfolio transfer taxes (if any), brokerage and other sim-
ilar expenses, all of which will be borne by the relevant Fund) incurred in
connection with the consummation of the transactions contemplated by the
Agreement will be [borne by CRM and/or Washington Mutual] [allocated in accor-
dance with the following: First, the costs of the overall restructuring of the
Composite/Sierra Mutual Funds referred to in the Overview under "Proposed
Transactions," including the costs of the Mergers and this Prospectus/Proxy
Statement, are being preliminarily allocated on a basis approved by the Trust-
ees, including the Independent Trustees, of the Trust as well as by the Trust-
ees of the Composite Funds, including the Trustees who are not "interested
persons" thereof, and Directors of the Composite Funds, including the Direc-
tors who are not "interested persons" thereof. CRM and/or Sierra will bear any
and all expenses preliminarily allocated to any of the series of Composite
Funds involved in the overall restructuring and CRM and/or Sierra will also
bear any and all expenses allocated to Sierra Funds, including the Global Gov-
ernment Fund and the High Quality Bond Fund to the extent that they would oth-
erwise exceed the respective expense caps (the "Relevant Expense Caps") set
forth below. The Sierra Funds, including the Global Government Fund and the
High Quality Bond Fund have agreed to pay the expenses preliminarily allocated
to them but not, however, in an amount exceeding the Relevant Expense Caps.
The Relevant Expense Caps represent a percentage (approximately 50%) of the
projected aggregate savings for shareholders for the first year following the
Mergers. The currently estimated expenses to be borne by the Funds and the
Relevant Expense Caps are as follows:

 Notwithstanding any of the foregoing, expenses will in any event be paid by
the party directly incurring such expenses if and to the extent that the pay-
ment by any other party of such expenses would result in the disqualification
of the first party as a "regulated investment company" within the meaning of
Section 851 of the Internal Revenue Code of 1986, as amended (the "Code")].
 
 DESCRIPTION OF THE MERGER SHARES. Full and fractional Merger Shares will be
issued to the Global Government Fund's shareholders in accordance with the
procedure under the Agreement as described above. The Merger Shares are Class
A, Class B, Class I and Class S shares of the High Quality Bond Fund, which
have characteristics identical to those of the corresponding class of the
Global Government Fund shares with respect to sales charges, CDSCs, conversion
and 12b-1 servicing and distribution fees. Investors purchasing Class A shares
of the High Quality Bond Fund generally pay a sales charge of up to 3.50% at
the time of purchase, but the Global Government Fund shareholders receiving
Class A Merger Shares in the Merger will not pay a sales charge on such
shares. Class A shares of the High Quality Bond Fund are generally not subject
to redemption fees, except that a $5.00 fee may be charged for each wire
transfer if shares are redeemed by wire transfer to a shareholder's pre-autho-
rized
 
                                      23

bank account. Certain investors who purchase Class A shares at net asset value
based on a purchase amount of $1 million or more after June 30, 1995 may be
subject to a 1.0% CDSC on redemptions within one year of purchase or a 0.5%
CDSC on redemptions after 1 year but within two years of purchase. Class A
shares purchased through a qualified 401(k) or 403(b) plan may, in certain
circumstances, be subject to a CDSC of 1.0% if the shares are redeemed within
two years of their initial purchase. Class A shares of the High Quality Bond
Fund are generally subject to a 12b-1 servicing fee at the annual rate of
0.25% of the net assets attributable to the Fund's Class A shares. Class B
shares of the High Quality Bond Fund are sold without a front end sales
charge, but are subject to a CDSC of up to 4% if redeemed within four years of
original purchase. Class S shares of the High Quality Bond Fund are sold with-
out a front end sales charge, but are subject to a CDSC of up to 5% if re-
deemed within six years of original purchase. Both Class B and Class S shares
of the High Quality Bond Fund are also subject to 12b-1 distribution and ser-
vicing fees at the annual rates of 0.75% and 0.25%, respectively, of the
Fund's average daily net assets attributable to Class B or Class S shares.
Class B and Class S shares of the High Quality Bond Fund will convert automat-
ically into Class A shares after they have been held for approximately eight
years. Class I shares of the High Quality Bond Fund (which are available for
purchase only by the SAM Portfolios and are not sold directly to investors)
are sold without a front-end sales load or CDSC, are not subject to 12b-1 fees
and do not convert into any other class of shares. For purposes of determining
the CDSC payable on redemption of Class A, Class B or Class S Merger Shares
received by holders of Class A, Class B or Class S shares of the Global Gov-
ernment Fund, as well as the conversion date of Class B and Class S Merger
Shares, such shares will be treated as having been acquired as of the dates
that, and for the prices at which, such shareholders originally acquired their
Class A, Class B or Class S shares, as the case may be, of the Global Govern-
ment Fund, and the CDSC will be applied at the same rate as was in effect for
the High Quality Bond Fund at the time the shares of the Global Government
Fund were originally purchased.
 
 CERTAIN PAYMENTS BY THE DISTRIBUTOR. In connection with the sale of Class B
and Class S shares of both the Global Government Fund and the High Quality
Bond Fund, Sierra Services pays commissions to broker-dealers from its own as-
sets that it expects to recover over time through the receipt of distribution
fees in connection with both the Global Government Fund's and the High Quality
Bond Fund's Class B and Class S shares and the receipt of any CDSC on Class B
and Class S shares. The total amount of such commissions paid by Sierra Serv-
ices with respect to the Funds before the consummation of the proposed Merger
will likely exceed the amounts recovered by Sierra Services by that time. Such
unrecovered amounts do not represent a liability of the Global Government Fund
and, consequently, the High Quality Bond Fund will not assume any such liabil-
ity in connection with the consummation of the Merger. However, to the extent
Sierra Services has not fully recovered such commissions before the consumma-
tion of the proposed Merger, it is anticipated that the Sierra Trustees will
consider such unrecovered amounts, among other factors, in determining whether
to continue payments of distribution fees in the future with respect to Class
B and Class S shares of the High Quality Bond Fund.
 
 As of June 30, 1997, the expenses incurred by Sierra Services in distributing
shares of the Trust were approximately $   in excess of payments under the
Trust's Distribution and Servicing Plan with respect to Class B shares and
$    in excess of payments under the Trust's Distribution and Servicing Plan
with respect to Class S shares.
 
 DECLARATION OF TRUST. Each of the Merger Shares will be fully paid and nonas-
sessable by the High Quality Bond Fund when issued, will be transferable with-
out restriction, and will have no preemptive or conversion rights, except that
Class B and Class S Merger Shares convert automatically
 
                                      24
<PAGE>
 
into Class A shares as described above. The Sierra Declaration of Trust per-
mits the Trust to divide its shares, without shareholder approval, into two or
more series of shares representing separate investment portfolios and to fur-
ther divide any such series, without shareholder approval, into two or more
classes of shares having such preferences and special or relative rights and
privileges as the Trustees may determine. The High Quality Bond Fund's shares
are currently divided into four classes: Class A, Class B, Class I and Class
S.
 
 Under Massachusetts law, shareholders of a Massachusetts business trust
could, under certain circumstances, be held personally liable for the obliga-
tions of the trust. However, the Sierra Declaration of Trust disclaims share-
holder liability for acts or obligations of the Trust and/or the High Quality
Bond Fund and requires that notice of such disclaimer be given in each agree-
ment, undertaking, or obligation entered into or executed by the Trust, the
High Quality Bond Fund or the Trust's Trustees. The Sierra Declaration of
Trust provides for indemnification out of the High Quality Bond Fund property
for all loss and expense of any shareholder held personally liable for the ob-
ligations of the High Quality Bond Fund. Thus, the risk of a shareholder's in-
curring financial loss from shareholder liability is limited to circumstances
in which the High Quality Bond Fund would be unable to meet its obligations.
The likelihood of such a circumstance is considered remote. The shareholders
of the Global Government Fund are currently subject to substantially the same
risk of shareholder liability, under Massachusetts law and the Sierra Declara-
tion of Trust.
 
 The Sierra Declaration of Trust provides that Trustees may be removed by two-
thirds vote of the Trustees or by vote of shareholders holding at least two-
thirds of the outstanding shares of the Trust. In addition, the Sierra Decla-
ration of Trust provides that shareholders holding 10% or more of the out-
standing shares of the Trust may call a meeting of shareholders to consider
the removal of any Trustee.
 
 The Sierra Declaration of Trust provides that the liquidation of any fund,
including the Global Government Fund, requires the approval not only of a ma-
jority of the Trustees, but also of a "majority of the outstanding voting se-
curities" of the fund, as defined in the 1940 Act, which means the lesser of
(A) 67% or more of the shares of the fund present at a meeting, if the holders
of more than 50% of the outstanding shares of the fund are present or repre-
sented by proxy, or (B) more than 50% of the outstanding shares of the fund.
The Sierra Declaration of Trust provides that the Trust may be terminated only
by both the vote of a majority of the outstanding voting securities of each
fund and the vote of a majority of the Trustees.
 
 The Sierra Declaration of Trust provides that a quorum for a meeting of
shareholders is a majority of the shares entitled to vote at the meeting.
 
 BOARD OF TRUSTEES. Pursuant to Proposal 1, each Trustee of The Composite
Funds has been nominated to serve as a Trustee of the Trust, subject to the
approval of the Trust's shareholders. The members of The Composite Funds'
Board of Trustees, who are responsible for overseeing the affairs of The Com-
posite Funds, are currently Wayne L. Attwood, M.D., Kristianne Blake, Anne V.
Farrell, Michael K. Murphy, William G. Papesh, Daniel L. Pavelich, Jay Rockey
and Richard C. Yancey. See Proposal 1 above for further information.
 
 CAPITALIZATION. The following table shows the capitalization of the High
Quality Bond Fund and the Global Government Fund as of June 30, 1997 and of
the High Quality Bond Fund on a pro forma basis as of that date, giving effect
to the proposed acquisition by the High Quality Bond Fund of the assets and
liabilities of the Global Government Fund at net asset value:

 Because the Agreement provides that the High Quality Bond Fund will be the
surviving Fund following the reorganization and because the High Quality Bond
Fund's investment objective and policies will remain unchanged, the pro forma
financial statements reflect the transfer of the assets and liabilities of the
Global Government Fund to the High Quality Bond Fund as contemplated by the
Agreement.

VOTING INFORMATION 

 RECORD DATE, QUORUM AND METHOD OF TABULATION. Shareholders of record of the
Global Government Fund at the close of business on October  , 1997 (the "Rec-
ord Date") will be entitled to notice of and to vote at the Meeting or any ad-
journment thereof. The holders of a majority of the Class A, Class B, Class I
and Class S shares of the Global Government Fund outstanding at the close of
business on the Record Date present in person or represented by proxy will
constitute a quorum for the Meeting with respect to that Fund. Shareholders
are entitled to one vote for each share held, with fractional shares voting
proportionally. Class A, Class B, Class I and Class S shareholders of the
Global Government Fund vote together as a single class in connection with the
approval or disapproval of the Merger. Only shareholders of the Global Govern-
ment Fund will vote on the approval or disapproval of the Merger. Shareholders
of all of the Funds within the Trust will vote together as a single class on
the election of the Trust's Board of Trustees.
 
                                      27
<PAGE>
 
 Votes cast by proxy or in person at the Meeting will be counted by persons
appointed by the Trust as tellers for the Meeting. The tellers will count the
total number of votes cast "for" approval of the proposal for purposes of de-
termining whether sufficient affirmative votes have been cast. The tellers
will count shares represented by proxies that reflect abstentions and "broker
non-votes" (i.e., shares held by brokers or nominees as to which (i) instruc-
tions have not been received from the beneficial owners or the persons enti-
tled to vote and (ii) the broker or nominee does not have the discretionary
voting power on a particular matter) as shares that are present and entitled
to vote on the matter for purposes of determining the presence of a quorum. So
long as a quorum is present, abstentions and broker non-votes have the effect
of negative votes on the proposals relating to the Mergers, and no effect on
the election of Trustees. Class I shares of the Global Government Fund which
are held by SAM Portfolios are required to be voted for, voted against or
withheld from voting on each Proposal in the same proportion as are the other
outstanding shares of the Global Government Fund.
 
 SHARES OUTSTANDING AND BENEFICIAL OWNERSHIP. As of the Record Date, as shown
on the books of the Trust, there were issued and outstanding the following
number of shares of beneficial interest of each class of the Global Government
Fund:

 As of the Record Date, the officers and Trustees of the Trust as a group ben-
eficially owned [less than 1%] of the outstanding shares of each class of the
Global Government Fund. As of the Record Date, to the best of the knowledge of
the Trust, the following persons owned of record or beneficially 5% or more of
the outstanding shares of the indicated classes of the Global Government Fund
and the High Quality Bond Fund:
 
 [insert list of 5% shareholders and pro forma ownership of the 5% sharehold-
ers following Merger]
 
 SOLICITATION OF PROXIES. Solicitation of proxies by personal interview, mail,
and telephone, may be made by officers and Trustees of the Trust and employees
of Sierra and CRM and their affiliates. In addition, the firm of     has been
retained to assist in the solicitation of proxies. The costs for solicitation
of proxies, like the other costs associated with the overall restructuring of
the Composite/Sierra Mutual Funds, will be [borne by CRM and/or Sierra] [only
partially borne by the Funds]. See "Information About the Merger."
 
 REVOCATION OF PROXIES. Any shareholder giving a proxy has the power to revoke
it by mail (addressed to the Trust's Secretary at the principal office of the
Trust at P.O. Box 5118, Westboro, Massachusetts 01581) or in person at the
Meeting, by executing a superseding proxy, or by submitting a notice of revo-
cation to the Secretary of the Trust. All properly executed proxies received
in time for the Meeting will be voted as specified in the proxy, or, if no
specification is made, FOR the election of all of the nominees to the Trust's
Board of Trustees (set forth in Proposal 1 of the Notice of Meeting) and FOR
the proposal (set forth in Proposals 2, of the Notice of Meeting) to implement
the Merger with respect to the Global Government Fund.
 
 SHAREHOLDER PROPOSALS AT FUTURE MEETINGS OF SHAREHOLDERS. The Sierra Declara-
tion of Trust does not provide for annual meetings of shareholders and the
Trust does not currently intend to hold such a meeting for shareholders in
1997 or 1998. Shareholder proposals for inclusion in a proxy statement for any
subsequent meeting of the Global Government Fund's shareholders must be re-
ceived by the Trust a reasonable period of time prior to any such meeting. If
the Merger is consummated, the Global Government Fund's existence will termi-
nate in December 1997 or shortly thereafter, after which there would be no
meetings

of the shareholders of the Global Government Fund.
 
 ADJOURNMENT. If sufficient votes in favor of any proposal are not received by
the time scheduled for the Meeting, the persons named as proxies may propose
one or more adjournments of the Meeting to permit further solicitation of
proxies. Any adjournment will require the affirmative vote of a plurality of
the votes cast on the question in person or by proxy at the session of the
Meeting to be adjourned. If the Meeting is adjourned only with respect to one
proposal, any other proposal may still be acted upon by the shareholders. The
persons named as proxies will vote in favor of such adjournment those proxies
which they are entitled to vote in favor of the proposal. They will vote
against any such adjournment those proxies required to be voted against the
proposal. [The Global Government Fund/CRM or its affiliates] will pay the
costs of any additional solicitation and of any adjourned session.

                                  APPENDIX A
 
                 FORM OF AGREEMENT AND PLAN OF REORGANIZATION
 
 This Agreement and Plan of Reorganization (the "Agreement") is made as of Oc-
tober    , 1997 in    ,   , by and between the Sierra Trust Funds, a Massachu-
setts business trust (the "Sierra Trust") on behalf of its Short Term Global
Government Fund series (the "Acquired Fund"), and the Sierra Trust, on behalf
of its Short Term High Quality Bond Fund series (the "Acquiring Fund").
 
PLAN OF REORGANIZATION
 
 (a) The Acquired Fund will sell, assign, convey, transfer and deliver to the
Acquiring Fund on the Exchange Date (as defined in Section 6) all of its prop-
erties and assets. In consideration therefor, the Acquiring Fund shall, on the
Exchange Date, assume all of the liabilities of the Acquired Fund existing at
the Valuation Time (as defined in Section 3(c)) and deliver to the Acquired
Fund (i) a number of full and fractional Class A shares of beneficial interest
of the Acquiring Fund (the "Class A Merger Shares") having an aggregate net
asset value equal to the value of the assets of the Acquired Fund attributable
to Class A shares of the Acquired Fund transferred to the Acquiring Fund on
such date less the value of the liabilities of the Acquired Fund attributable
to Class A shares of the Acquired Fund assumed by the Acquiring Fund on that
date, (ii) a number of full and fractional Class B shares of beneficial inter-
est of the Acquiring Fund (the "Class B Merger Shares") having an aggregate
net asset value equal to the value of the assets of the Acquired Fund attrib-
utable to Class B shares of the Acquired Fund transferred to the Acquiring
Fund on such date less the value of the liabilities of the Acquired Fund at-
tributable to Class B shares of the Acquired Fund assumed by the Acquiring
Fund on that date, (iii) a number of full and fractional Class I shares of
beneficial interest of the Acquiring Fund (the "Class I Merger Shares") having
an aggregate net asset value equal to the value of the assets of the Acquired
Fund attributable to Class I shares of the Acquired Fund transferred to the
Acquiring Fund on such date less the value of the liabilities of the Acquired
Fund attributable to Class I shares of the Acquired Fund assumed by the Ac-
quiring Fund on that date and (iv) a number of full and fractional Class S
shares of beneficial interest of the Acquiring Fund (the "Class S Merger
Shares") having an aggregate net asset value equal to the value of the assets
of the Acquired Fund attributable to Class S shares of the Acquired Fund
transferred to the Acquiring Fund on such date less the value of the liabili-
ties of the Acquired Fund attributable to Class S shares of the Acquired Fund
assumed by the Acquiring Fund on that date. (The Class A Merger Shares, the
Class B Merger Shares, the Class I Merger Shares and the Class S Merger Shares
shall be referred to collectively as the "Merger Shares.") It is intended that
the reorganization described in this Agreement shall be a reorganization
within the meaning of Section 368 of the Internal Revenue Code of 1986, as
amended (the "Code").
 
 (b) Upon consummation of the transactions described in paragraph (a) of this
Agreement, the Acquired Fund shall distribute in complete liquidation to its
Class A, Class B, Class I and Class S shareholders of record as of the Ex-
change Date the Class A, Class B, Class I and Class S Merger Shares of the Ac-
quiring Fund, each such shareholder being entitled to receive that proportion
of such Class A, Class B, Class I and Class S Merger Shares which the number
of Class A, Class B, Class I and Class S shares of beneficial interest of the
Acquired Fund held by such shareholder bears to the number of Class A, Class
B, Class I and Class S shares of the Acquired Fund outstanding on such date.
Certificates representing the Merger Shares will
 
                                      A-1
<PAGE>
 
not be issued. All issued and outstanding shares of the Acquired Fund will si-
multaneously be canceled on the books of the Acquired Fund.
 
 (c) As promptly as practicable after the liquidation of the Acquired Fund as
aforesaid, the Acquired Fund shall be dissolved pursuant to the provisions of
the Declaration of Trust of the Sierra Trust, as amended, and applicable law,
and its legal existence terminated. Any reporting responsibility of the Ac-
quired Fund is and shall remain the responsibility of the Acquired Fund up to
and including the Exchange Date and, if applicable, such later date on which
the Acquired Fund is liquidated.
 
AGREEMENT
 
 The Acquiring Fund and the Acquired Fund agree as follows:
 
 1. Representations, Warranties and Agreements of the Acquiring Fund. The Ac-
quiring Fund represents and warrants to and agrees with the Acquired Fund
that:
 
  a. The Acquiring Fund is a series of shares of the Sierra Trust, a Massachu-
 setts business trust duly established and validly existing under the laws of
 The Commonwealth of Massachusetts, and has power to own all of its properties
 and assets and to carry out its obligations under this Agreement. The Sierra
 Trust is qualified as a foreign association in every jurisdiction where re-
 quired, except to the extent that failure to so qualify would not have a ma-
 terial adverse effect on the Sierra Trust. Each of the Sierra Trust and the
 Acquiring Fund has all necessary federal, state and local authorizations to
 carry on its business as now being conducted and to carry out this Agreement.
 
  b. The Sierra Trust is registered under the Investment Company Act of 1940,
 as amended (the "1940 Act"), as an open-end management investment company,
 and such registration has not been revoked or rescinded and is in full force
 and effect.
 
  c. A statement of assets and liabilities, statements of operations, state-
 ments of changes in net assets and a schedule of investments (indicating
 their market values) of the Acquiring Fund as of and for the year ended June
 30, 1997 have been furnished to the Acquired Fund. Such statement of assets
 and liabilities and schedule fairly present the financial position of the Ac-
 quiring Fund as of the their date and such statements of operations and
 changes in net assets fairly reflect the results of its operations and
 changes in net assets for the period covered thereby in conformity with gen-
 erally accepted accounting principles.
 
  d. The current prospectus and statement of additional information of the Si-
 erra Trust, each dated October 31, 1997 (collectively, the "Sierra Prospec-
 tus"), which has previously been furnished to the Acquired Fund, did not as
 of such date and does not contain as of the date hereof, with respect to the
 Sierra Trust and the Acquiring Fund, any untrue statements of a material fact
 or omit to state a material fact required to be stated therein or necessary
 to make the statements therein not misleading.
 
  e. There are no material legal, administrative or other proceedings pending
 or, to the knowledge of the Sierra Trust or the Acquiring Fund, threatened
 against the Sierra Trust or the Acquiring Fund, which assert liability on the
 part of the Sierra Trust or the Acquiring Fund. The Acquiring Fund knows of
 no facts which might form the basis for the institution of such proceedings
 and is not a party to or subject to the provisions of any order, decree or
 judgment of any court or governmental body which materially and adversely af-
 fects its business or its ability to consummate the transactions herein con-

 supplemented by any amendments or supplements filed with the Commission by
 the Sierra Trust, and the Acquired Fund Proxy Statement will not contain any
 untrue statement of a material fact or omit to state a material fact required
 to be stated therein or necessary to make the statements therein not mislead-
 ing; provided, however, that none of the representations and warranties in
 this subsection shall apply to statements in or omissions from the Registra-

 in conformity with information furnished in writing by the Acquired Fund to
 the Acquiring Fund or the Sierra Trust specifically for use in the Registra-

 standing. All of the issued and outstanding shares of beneficial interest of
 the Acquiring Fund have been offered

<PAGE>
 
 for sale and sold in conformity with all applicable federal and state securi-
 ties laws (including any applicable exemptions therefrom), or the Acquiring
 Fund has taken any action necessary to remedy any prior failure to have of-
 fered for sale and sold such shares in conformity with such laws.
 
  l. The Acquiring Fund qualifies and will at all times through the Exchange
 Date qualify for taxation as a "regulated investment company" under Sections
 851 and 852 of the Code.
 
  m. The issuance of the Merger Shares pursuant to this Agreement will be in
 compliance with all applicable federal and state securities laws.
 
  n. The Merger Shares to be issued to the Acquired Fund have been duly autho-
 rized and, when issued and delivered pursuant to this Agreement, will be le-
 gally and validly issued and will be fully paid and non-assessable by the Ac-
 quiring Fund, and no shareholder of the Acquiring Fund will have any preemp-
 tive right of subscription or purchase in respect thereof.
 
  o. All issued and outstanding shares of the Acquiring Fund are, and at the
 Exchange Date all issued and outstanding shares of the Acquiring Fund will
 be, duly authorized, validly issued, fully paid and non-assessable by the Ac-

 rants or other rights to subscribe for or purchase any Acquiring Fund shares,
 nor is there outstanding any security convertible into any Acquiring Fund
 shares.
 
 2. Representations, Warranties and Agreements of the Acquired Fund. The Ac-
quired Fund represents and warrants to and agrees with the Acquiring Fund
that:
 
  a. The Acquired Fund is a series of shares of the Sierra Trust, a Massachu-
 setts business trust duly established and validly existing under the laws of
 The Commonwealth of Massachusetts, and has power to own all of its properties
 and assets and to carry out this Agreement. The Sierra Trust is qualified as
 a foreign association in every jurisdiction where required, except to the ex-
 tent that failure to so qualify would not have a material adverse effect on
 the Sierra Trust. Each of the Sierra Trust and the Acquired Fund has all nec-
 essary federal, state and local authorizations to own all of its properties
 and assets and to carry on its business as now being conducted and to carry
 out this Agreement.
 
  b. The Sierra Trust is registered under the 1940 Act as an open-end manage-
 ment investment company, and such registration has not been revoked or re-
 scinded and is in full force and effect.
 
  c. A statement of assets and liabilities, statement of operations, statement
 of changes in net assets and a schedule of investments (indicating their mar-
 ket values) of the Acquired Fund as of and for the year ended June 30, 1997
 have been furnished to the Acquiring Fund. Such statement of assets and lia-
 bilities and schedule fairly present the financial position of the Acquired
 Fund as of their date, and such statements of operations and changes in net
 assets fairly reflect the results of its operations and changes in net assets
 for the period covered thereby, in conformity with generally accepted ac-
 counting principles.
 
  d. The Sierra Prospectus, which has been previously furnished to the Acquir-
 ing Fund, did not contain as of such dates and does not contain, with respect
 to the Sierra Trust and the Acquired Fund, any untrue statement of a material
 fact or omit to state a material fact required to be stated therein or neces-
 sary to make the statements therein not misleading.
 
  e. There are no material legal, administrative or other proceedings pending
 or, to the knowledge of the Sierra Trust or the Acquired Fund, threatened
 against the Sierra Trust or the Acquired Fund, which assert liability on the
 part of
 
                                      A-4
<PAGE>
 
 the Sierra Trust or the Acquired Fund. The Acquired Fund knows of no facts
 which might form the basis for the institution of such proceedings and is not
 a party to or subject to the provisions of any order, decree or judgment of
 any court or governmental body which materially and adversely affects its
 business or its ability to consummate the transactions herein contemplated.
 
  f. There are no material contracts outstanding to which the Acquired Fund is
 a party, other than as are disclosed in the Sierra Trust's registration
 statement on Form N-1A or the Sierra Prospectus.
 
  g. The Acquired Fund has no known liabilities of a material nature, contin-
 gent or otherwise, other than those shown on the Acquired Fund's statement of
 assets and liabilities as of June 30, 1997 referred to above and those in-
 curred in the ordinary course of its business as an investment company since
 such date. Prior to the Exchange Date, the Acquired Fund will endeavor to
 quantify and to reflect on its balance sheet all of its material known lia-
 bilities and will advise the Acquiring Fund of all material liabilities, con-
 tingent or otherwise, incurred by it subsequent to June 30, 1997, whether or
 not incurred in the ordinary course of business.
 
  h. As of the Exchange Date, the Acquired Fund will have filed all federal
 and other tax returns and reports which, to the knowledge of the Sierra
 Trust's officers, are required to be filed by the Acquired Fund and has paid
 or will pay all federal and other taxes shown to be due on said returns or on
 any assessments received by the Acquired Fund. All tax liabilities of the Ac-
 quired Fund have been adequately provided for on its books, and no tax defi-
 ciency or liability of the Acquired Fund has been asserted, and no question
 with respect thereto has been raised or is under audit, by the Internal Reve-
 nue Service or by any state or local tax authority for taxes in excess of
 those already paid.
 
  i. At the Exchange Date, the Sierra Trust, on behalf of the Acquired Fund,
 will have full right, power and authority to sell, assign, transfer and de-
 liver the Investments (as defined below) and any other assets and liabilities
 of the Acquired Fund to be transferred to the Acquiring Fund pursuant to this
 Agreement. At the Exchange Date, subject only to the delivery of the Invest-
 ments and any such other assets and liabilities as contemplated by this
 Agreement, the Acquiring Fund will acquire the Investments and any such other
 assets and liabilities subject to no encumbrances, liens or security inter-
 ests whatsoever and without any restrictions upon the transfer thereof. As
 used in this Agreement, the term "Investments" shall mean the Acquired Fund's
 investments shown on the schedule of its investments as of June 30, 1997 re-
 ferred to in Section 2(c) hereof, as supplemented with such changes in the
 portfolio as the Acquired Fund shall make, and changes resulting from stock
 dividends, stock split-ups, mergers and similar corporate actions through the
 Exchange Date.
 
  j. No registration under the 1933 Act of any of the Investments would be re-
 quired if they were, as of the time of such transfer, the subject of a public
 distribution by either of the Acquiring Fund or the Acquired Fund, except as
 previously disclosed to the Acquiring Fund by the Acquired Fund.
 
  k. No consent, approval, authorization or order of any court or governmental
 authority is required for the consummation by the Acquired Fund of the trans-
 actions contemplated by this Agreement, except such as may be required under
 the 1933 Act, 1934 Act, the 1940 Act or state securities or blue sky laws.
 
  l. The Registration Statement and the Acquired Fund Proxy Statement, on the
 effective date of the Registration Statement, (i) will comply in all material
 respects with the provisions of the 1933 Act, the 1934 Act and the 1940 Act
 and the rules and regulations thereunder and
 
                                      A-5
<PAGE>
 
 (ii) will not contain any untrue statement of a material fact or omit to
 state a material fact required to be stated therein or necessary to make the
 statements therein not misleading; and at the time of the shareholders meet-
 ing referred to in Section 7(a) and on the Exchange Date, the Acquired Fund
 Proxy Statement and the Registration Statement will not contain any untrue
 statement of a material fact or omit to state a material fact required to be
 stated therein or necessary to make the statements therein not misleading;
 provided, however, that none of the representations and warranties in this
 subsection shall apply to statements in or omissions from the Registration
 Statement or the Acquired Fund Proxy Statement made in reliance upon and in
 conformity with information furnished in writing by the Acquiring Fund to the
 Acquired Fund or the Sierra Trust specifically for use in the Registration
 Statement or the Acquired Fund Proxy Statement.
 
  m. The Acquired Fund qualifies and will at all times through the Exchange
 Date qualify for taxation as a "regulated investment company" under Section
 851 and 852 of the Code.
 
  n. At the Exchange Date, the Acquired Fund will have sold such of its as-
 sets, if any, as are necessary to assure that, after giving effect to the ac-
 quisition of the assets of the Acquired Fund pursuant to this Agreement, the
 Acquiring Fund will remain a "diversified company" within the meaning of Sec-
 tion 5(b)(1) of the 1940 Act and in compliance with such other mandatory in-
 vestment restrictions as are set forth in the Sierra Prospectus, as amended
 through the Exchange Date.
 
  o. All of the issued and outstanding shares of beneficial interest of the
 Acquired Fund shall have been offered for sale and sold in conformity with
 all applicable federal and state securities laws (including any applicable
 exemptions therefrom), or the Acquired Fund has taken any action necessary to
 remedy any prior failure to have offered for sale and sold such shares in
 conformity with such laws.
 
  p. All issued and outstanding shares of the Acquired Fund are, and at the
 Exchange Date will be, duly authorized, validly issued, fully paid and non-
 assessable by the Acquired Fund. The Acquired Fund does not have outstanding
 any options, warrants or other rights to subscribe for or purchase any of the
 Acquired Fund shares, nor is there outstanding any security convertible into
 any of the Acquired Fund shares.
 
 3. Reorganization.
 
  a. Subject to the requisite approval of the shareholders of the Acquired
 Fund and to the other terms and conditions contained herein (including the
 Acquired Fund's obligation to distribute to its shareholders all of its in-
 vestment company taxable income and net capital gain as described in Section
 8(m)), the Acquired Fund agrees to sell, assign, convey, transfer and deliver
 to the Acquiring Fund, and the Acquiring Fund agrees to acquire from the Ac-
 quired Fund, on the Exchange Date all of the Investments and all of the cash
 and other properties and assets of the Acquired Fund, whether accrued or con-
 tingent (including cash received by the Acquired Fund upon the liquidation by
 the Acquired Fund of any investments purchased by the Acquired Fund after
 June 30, 1997 and designated by the Acquiring Fund as being unsuitable for it
 to acquire), in exchange for that number of shares of beneficial interest of
 the Acquiring Fund provided for in Section 4 and the assumption by the Ac-
 quiring Fund of all of the liabilities of the Acquired Fund, whether accrued
 or contingent, existing at the Valuation Time except for the Acquired Fund's
 liabilities, if any, arising in connection with this Agreement. Pursuant to
 this Agreement, the Acquired Fund will, as soon as practicable after the
 Exchange Date, distribute all of the Merger Shares received by it to the
 shareholders of the
 
                                      A-6
<PAGE>
 
 Acquired Fund in exchange for their Class A, Class B, Class I and Class S
 shares of the Acquired Fund.
 
  b. The Acquired Fund will pay or cause to be paid to the Acquiring Fund any
 interest, cash or such dividends, rights and other payments received by it on
 or after the Exchange Date with respect to the Investments and other proper-
 ties and assets of the Acquired Fund, whether accrued or contingent, received
 by it on or after the Exchange Date. Any such distribution shall be deemed
 included in the assets transferred to the Acquiring Fund at the Exchange Date
 and shall not be separately valued unless the securities in respect of which
 such distribution is made shall have gone "ex" such distribution prior to the
 Valuation Time, in which case any such distribution which remains unpaid at
 the Exchange Date shall be included in the determination of the value of the
 assets of the Acquired Fund acquired by the Acquiring Fund.
 
  c. The Valuation Time shall be 4:00 p.m. Eastern time on [the Exchange Date]
 or such earlier or later day as may be mutually agreed upon in writing by the
 parties hereto (the "Valuation Time").
 
 4. Exchange Date: Valuation Time. On the Exchange Date, the Acquiring Fund
will deliver to the Acquired Fund (i) a number of full and fractional Class A
Merger Shares having an aggregate net asset value equal to the value of the
assets of the Acquired Fund attributable to Class A shares of the Acquired
Fund transferred to the Acquiring Fund on such date less the value of the lia-
bilities of the Acquired Fund attributable to Class A shares of the Acquired
Fund assumed by the Acquiring Fund on that date, (ii) a number of full and
fractional Class B Merger Shares having an aggregate net asset value equal to
the value of the assets of the Acquired Fund attributable to Class B shares of
the Acquired Fund transferred to the Acquiring Fund on such date less the
value of the liabilities of the Acquired Fund attributable to Class B shares
of the Acquired Fund assumed by the Acquiring Fund on that date, (iii) a num-
ber of full and fractional Class I Merger Shares having an aggregate net asset
value equal to the value of the assets of the Acquired Fund attributable to
Class I shares of the Acquired Fund transferred to the Acquiring Fund on such
date less the value of the liabilities of the Acquired Fund attributable to
Class I shares of the Acquired Fund assumed by the Acquiring Fund on that date
and (iv) a number of full and fractional Class S Merger Shares having an ag-
gregate net asset value equal to the value of the assets of the Acquired Fund
attributable to Class S shares of the Acquired Fund transferred to the Acquir-
ing Fund on such date less the value of the liabilities of the Acquired Fund
attributable to Class S shares of the Acquired Fund assumed by the Acquiring
Fund on that date, determined as hereinafter provided in this Section 4.
 
  a. The net asset value of the Merger Shares to be delivered to the Acquired
 Fund, the value of the assets attributable to the shares of the Acquired
 Fund, and the value of the liabilities attributable to the Class A, Class B,
 Class I and Class S shares of the Acquired Fund to be assumed by the Acquir-
 ing Fund, shall in each case be determined as of the Valuation Time.
 
  b. The net asset value of the Class A, Class B, Class I and Class S Merger
 Shares shall be computed in the manner set forth in the Sierra Prospectus.
 The value of the assets and liabilities of the Class A, Class B, Class I and
 Class S shares of the Acquired Fund shall be determined by the Acquiring
 Fund, in cooperation with the Acquired Fund, pursuant to procedures which the
 Acquiring Fund would use in determining the fair market value of the Acquir-
 ing Fund's assets and liabilities.
 
  c. No adjustment shall be made in the net asset value of either the Acquired
 Fund or the Acquiring Fund to take into account differences in realized and
 unrealized gains and losses.
 
                                      A-7
<PAGE>
 
  d. The Acquiring Fund shall issue the Merger Shares to the Acquired Fund in
 four certificates registered in the name of the Acquired Fund, one represent-
 ing Class A Merger Shares, one representing Class B Merger Shares, one repre-
 senting Class I Merger Shares and one representing Class S Merger Shares. The
 Acquired Fund shall distribute the Class A Merger Shares to the Class A
 shareholders of the Acquired Fund by redelivering such certificate to the Ac-
 quiring Fund's transfer agent, which will as soon as practicable set up open
 accounts for each Class A Acquired Fund shareholder in accordance with writ-
 ten instructions furnished by the Acquired Fund. The Acquired Fund shall dis-
 tribute the Class B Merger Shares to the Class B shareholders of the Acquired
 Fund by redelivering such certificate to the Acquiring Fund's transfer agent,
 which will as soon as practicable set up open accounts for each Class B Ac-
 quired Fund shareholder in accordance with written instructions furnished by
 the Acquired Fund. The Acquired Fund shall distribute the Class I Merger
 Shares to the Class I shareholders of the Acquired Fund by redelivering such
 certificate to the Acquiring Fund's transfer agent, which will as soon as
 practicable set up open accounts for each Class I Acquired Fund shareholder
 in accordance with written instructions furnished by the Acquired Fund. The
 Acquired Fund shall distribute the Class S Merger Shares to the Class S
 shareholders of the Acquired Fund by redelivering such certificate to the Ac-
 quiring Fund's transfer agent, which will as soon as practicable set up open
 accounts for each Class S Acquired Fund shareholder in accordance with writ-
 ten instructions furnished by the Acquired Fund. [With respect to any Ac-
 quired Fund shareholder holding share certificates as of the Exchange Date,
 such certificates will from and after the Exchange Date be deemed to be cer-
 tificates for the Merger Shares issued to each shareholder in respect of the
 Acquired Fund shares represented by such certificates; certificates repre-
 senting the Merger Shares will not be issued to Acquired Fund shareholders.]
 
  e. The Acquiring Fund shall assume all liabilities of the Acquired Fund,
 whether accrued or contingent, in connection with the acquisition of assets
 and subsequent dissolution of the Acquired Fund or otherwise, except for the
 Acquired Fund's liabilities, if any, pursuant to this Agreement.
 
 5. Expenses, Fees, etc.
 
  a. The parties hereto understand and agree that the transactions contem-
 plated by this Agreement are being undertaken contemporaneously with a gen-
 eral restructuring and consolidation of certain of the registered investment
 companies advised by Composite Research & Management Company and Sierra In-
 vestment Advisors Corporation and their affiliates; and that in connection
 therewith the costs of all such transactions are being [borne by Sierra In-
 vestment Advisors Corporation] [preliminarily allocated on a basis approved,
 inter alia, by the Trustees of the Trust. Each of the Acquired Fund and the
 Acquiring Fund agrees to pay the expenses preliminarily allocated to it but
 not, however, in an amount exceeding $    and $   , respectively (the "Rele-
 vant Expense Cap"). Sierra Investment Advisors Corporation will bear any and
 all expenses (1) preliminarily allocated to Acquiring Fund and (2) prelimina-
 rily allocated to the Acquired Fund, in each case to the extent that they
 would otherwise exceed the Relevant Expense Cap.] Notwithstanding any of the
 foregoing, expenses will in any event be paid by the party directly incurring
 such expenses if and to the extent that the payment by the other party of
 such expenses would result in the disqualification of such party as a "regu-
 lated investment company" within the meaning of Section 851 of the Code.
 
  b. In the event the transactions contemplated by this Agreement are not con-
 summated by
 
                                      A-8
<PAGE>
 
 reason of the Acquiring Fund's being either unwilling or unable to go forward
 other than by reason of the nonfulfillment or failure of any condition to the
 Acquiring Fund's obligations referred to in Section 7(a) or Section 8, the
 Acquiring Fund shall pay directly all reasonable fees and expenses incurred
 by the Acquired Fund in connection with such transactions, including, without
 limitation, legal, accounting and filing fees.
 
  c. In the event the transactions contemplated by this Agreement are not con-
 summated by reason of the Acquired Fund's being either unwilling or unable to
 go forward other than by reason of the nonfulfillment or failure of any con-
 dition to the Acquired Fund's obligations referred to in Section 7(a) or Sec-
 tion 9, the Acquired Fund shall pay directly all reasonable fees and expenses
 incurred by the Acquiring Fund in connection with such transactions, includ-
 ing, without limitation, legal, accounting and filings fees.
 
  d. In the event the transactions contemplated by this Agreement are not con-
 summated for any reason other than (i) the Acquiring Fund's or the Acquired
 Fund's being either unwilling or unable to go forward or (ii) the nonfulfill-
 ment or failure of any condition to the Acquiring Fund's or the Acquired
 Fund's obligations referred to in Section 7(a), Section 8 or Section 9 of
 this Agreement, then each of the Acquiring Fund and the Acquired Fund shall
 bear all of its own expenses incurred in connection with such transactions.
 
  e. Notwithstanding any other provisions of this Agreement, if for any reason
 the transactions contemplated by this Agreement are not consummated, no party
 shall be liable to the other party for any damages resulting therefrom, in-
 cluding, without limitation, consequential damages, except as specifically
 set forth above.
 
 6. Exchange Date. Delivery of the assets of the Acquired Fund to be trans-
ferred, assumption of the liabilities of the Acquired Fund to be assumed and
the delivery of the Merger Shares to be issued shall be made at [place] at
[time] as of December [31], 1997, or at such other time and date agreed to by
the Acquiring Fund and the Acquired Fund, the date and time upon which such
delivery is to take place being referred to herein as the "Exchange Date."
 
 7. Meetings of Shareholders; Dissolution.
 
  a. The Sierra Trust, on behalf of the Acquired Fund, agrees to call a meet-
 ing of the Acquired Fund's shareholders as soon as is practicable after the
 effective date of the Registration Statement for the purpose of considering
 the sale of all of its assets to and the assumption of all of its liabilities
 by the Acquiring Fund as herein provided, adopting this Agreement, and autho-
 rizing the liquidation and dissolution of the Acquired Fund.
 
  b. The Acquired Fund agrees that the liquidation and dissolution of the Ac-
 quired Fund will be effected in the manner provided in the Sierra Trust's
 Declaration of Trust in accordance with applicable law and that on and after
 the Exchange Date, the Acquired Fund shall not conduct any business except in
 connection with its liquidation and dissolution.
 
  c. The Acquiring Fund has, in consultation with the Acquired Fund and based
 in part on information furnished by the Acquired Fund, filed the Registration
 Statement with the Commission. The Acquired Fund and the Acquiring Fund will
 cooperate with each other and will furnish to each other the information re-
 lating to itself required by the 1933 Act, the 1934 Act and the 1940 Act and
 the rules and regulations thereunder to be set forth in the Registration
 Statement.

 The Commonwealth of Massachusetts and has the power to own all its properties

 delivery of this Agreement by the Sierra Trust on behalf of the Acquiring
 Fund, is a valid and binding obligation of the Sierra Trust and the Acquired
 Fund; (iii) the Sierra Trust, on behalf of the Acquired Fund, has power to

 this subparagraph, the "Indemnified Parties") against any and all expenses,
 losses, claims, damages and liabilities at any time imposed upon or reasona-
 bly incurred by any one or more of the Indemnified Parties in connection
 with, arising out of, or resulting from any claim, action, suit or proceeding
 in which any one or more of the Indemnified Parties may be involved or with
 which any one or more of the Indemnified Parties may be threatened by reason
 of any untrue statement or alleged untrue statement of a material fact relat-
 ing to the Sierra Trust or the Acquired Fund contained in the Registration
 Statement or the Sierra Prospectus, the Acquired Fund Proxy Statement or any
 amendment or supplement to any of the foregoing, or arising out of or based
 upon the omission or alleged omission to state in any of the foregoing a ma-
 terial fact relating to the Sierra Trust or the Acquired Fund required to be
 stated therein or necessary to make the statements relating to the Sierra
 Trust or the Acquired Fund therein not misleading, including, without limita-
 tion, any amounts paid by any one or more of the Indemnified Parties in a
 reasonable compromise or settlement of any such claim, action, suit or pro-
 ceeding, or threatened claim, action, suit or proceeding made with the con-
 sent of the Sierra Trust or the Acquired Fund. The Indemnified Parties will
 notify the Sierra Trust and the Acquired Fund in writing within ten days af-

 participate at its own expense in the defense of any claim, action, suit or
 proceeding covered by this Section 10(a), or, if it so elects, to assume at
 its expense by counsel satisfactory to the Indemnified Parties the defense of
 any such claim, action, suit or proceeding, and if the Acquired Fund elects

 pate in the defense of any such claim, action, suit or proceeding at their
 expense. The Acquired Fund's obligation under Section 10(a) to indemnify and
 hold harmless the Indemnified parties shall constitute a guarantee of payment
 so that the Acquired Fund will pay in the first instance any expenses, loss-
 es, claims, damages and liabilities required to be paid by it under this Sec-
 tion 10(a) without the necessity of the Indemnified Parties' first paying the
 same.
 
  b. The Acquiring Fund will indemnify and hold harmless, out of the assets of
 the Acquiring Fund but no other assets, the trustees and officers of the Si-
 erra Trust (for purposes of this subparagraph, the "Indemnified Parties")

 time imposed upon or reasonably incurred by any one or more of the Indemni-
 fied Parties in connection with, arising out of, or resulting from any claim,
 action, suit or proceeding in which any one or more of the Indemnified Par-
 ties may be involved or with which any one or more of the Indemnified Parties
 may be threatened by reason of any untrue statement or alleged untrue state-
 ment of a material fact relating to the Acquiring Fund contained in the Reg-
 istration Statement, the Sierra Prospectus, the Acquired Fund Proxy Statement
 or any amendment or supplement to any of the foregoing, or arising out of or
 based upon, the omission or alleged omission to state in any of the foregoing
 a material fact relating to the Sierra Trust or the Acquiring Fund required
 to be stated therein or necessary to make the statements relating to the Si-
 erra Trust or the Acquiring Fund therein not misleading, including, without
 limitation, any amounts paid by any one or more of the Indemnified Parties in
 a reasonable compromise or settlement of any such claim, action, suit or pro-
 ceeding, or threatened claim, action, suit or proceeding made with the con-
 sent of the Sierra Trust or the Acquiring Fund. The Indemnified Parties will
 notify the Sierra Trust and the Acquiring Fund in writing within ten days af-
 ter the receipt by any one or more of the Indemnified parties of any notice
 of legal process or any suit brought against or claim made against such In-
 demnified Party as to any matters covered by this Section 10(b). The Acquir-
 ing Fund shall be entitled to participate at its own expense in the defense
 of any claim, action, suit or proceeding covered by this Section 10(b), or,
 if it so elects, to assume at its expense by counsel satisfactory to the In-
 demnified Parties the defense of any such clam, action, suit or proceeding,
 and, if the Acquiring Fund elects to assume such defense, the Indemnified
 Parties shall be entitled to participate in the defense of any such claim,
 action, suit or proceeding at their own expense. The Acquiring Fund's obliga-
 tion under this Section 10(b) to indemnify and hold harmless the Indemnified
 Parties shall constitute a guarantee of payment so that the Acquiring Fund
 will pay in the first instance any expenses, losses, claims, damages and lia-
 bilities required to be paid by it under this Section 10(b) without the ne-
 cessity of the Indemnified Parties' first paying the same.
 
 11. No Broker, etc. Each of the Acquired Fund and the Acquiring Fund repre-
sents that there is no person who has dealt with it or the Sierra Trust who by
reason of such dealings is entitled to any broker's or finder's or other simi-
lar fee or commission arising out of the transactions contemplated by this
Agreement.
 
 12. Termination. The Acquired Fund and the Acquiring Fund may, by mutual con-
sent of the trustees of the Sierra Trust on behalf of each Fund, terminate
this Agreement, and the Acquired Fund
 
                                     A-15

or the Acquiring Fund, after consultation with counsel and by consent of their
respective trustees or an officer authorized by such trustees, may waive any
condition to their respective obligations hereunder. If the transactions con-
templated by this Agreement have not been substantially completed by [    ,
1998], this Agreement shall automatically terminate on that date unless a
later date is agreed to by the Acquired Fund and the Acquiring Fund.
 
 13. Rule 145. Pursuant to Rule 145 under the 1933 Act, the Acquiring Fund
will, in connection with the issuance of any of any Merger Shares to any per-
son who at the time of the transaction contemplated hereby is deemed to be an
affiliate of a party to the transaction pursuant to Rule 145(c), cause to be
affixed upon the certificates issued to such person (if any) a legend as fol-
lows:
 
  "THESE SHARES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT TO THE SHORT
 TERM HIGH QUALITY BOND FUND OR ITS PRINCIPAL UNDERWRITER UNLESS (I) A REGIS-
 TRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT
 OF 1933, AS AMENDED, OR (II) IN THE OPINION OF COUNSEL REASONABLY SATISFAC-
 TORY TO THE FUND SUCH REGISTRATION IS NOT REQUIRED."
 
and, further, the Acquiring Fund will issue stop transfer instructions to the
Acquiring Fund's transfer agent with respect to such shares. The Acquired Fund
will provide the Acquiring Fund on the Exchange Date with the name of any
Acquired Fund shareholder who is to the knowledge of the Acquired Fund an
affiliate of the Acquired Fund on such date.
 
 14. Covenants, etc. Deemed Material. All covenants, agreements, representa-
tions and warranties made under this Agreement and any certificates delivered
pursuant to this Agreement shall be deemed to have been material and relied
upon by each of the parties, notwithstanding an investigation made by them or
on their behalf.
 
 15. Sole Agreement; Amendments. This Agreement supersedes all previous corre-
spondence and oral communications between the parties regarding the subject
matter hereof, constitutes the only understanding with respect to such subject
matter, may not be changed except by a letter of agreement signed by each
party hereto, and shall be construed in accordance with and governed by the
laws of The Commonwealth of Massachusetts.

Trust is on file with the Secretary of State of The Commonwealth of Massachu-
setts, and notice is hereby given that this instrument is executed on behalf

  SHORT TERM HIGH QUALITY BOND FUND
- --------------------------------------------------------------------------------

PERFORMANCE REVIEW:

From the Fund's inception (November 1, 1993) through June 30, 1997, the Sierra
Short Term High Quality Bond Fund (Class A Shares) advanced 4.04% on an average
annual total return basis, or 3.03% adjusted for the maximum sales charge. For
the 12-month period ended June 30, 1997, the Fund's total return was 6.15%, or
2.44% adjusted for the maximum sales charge. The Fund's 30-day SEC yield as of
June 30, 1997, was 5.86%. For additional information, including Class B and
Class S Share performance, see the accompanying chart.

WHAT WERE THE MOST SIGNIFICANT FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE
OVER THE 12-MONTH PERIOD ENDED JUNE 30, 1997?

The most significant factors contributing to the Fund's performance over the
past 12 months were the generation of income combined with the strong
performance of the Fund's corporate and mortgage-backed holdings. Although rates
over the last six months rose slightly, interest rates over the entire 12-month
period fell. Our focus on producing consistent income for the Fund played an
important role in generating positive total returns over the 12-month period.

* Index total returns were calculated from 10/31/93 to 6/30/97. The Lehman
Brothers Mutual Fund Short (1-5) Investment Grade Debt Index includes all
investment-grade, corporate debt securities with maturities of one to five
years, assumes reinvestment of all dividends/distributions, and does not reflect
any asset-based charges for investment management or other expenses. Past
performance does not guarantee future performance. The returns shown for the
Fund assume reinvestment of all dividends/distributions by the shareholder.

During the period noted, the Advisor (SIERRA Investment Advisors Corporation)
and Administrator (SIERRA Fund Administration Corporation) waived a portion of
their management fees, the Advisor absorbed other expenses, and credits were
allowed by the Custodian. In the absence of the waivers and absorption of other
expenses or Custodian credits, yield and total return would have been lower.

WHAT MARKET CONDITIONS AFFECTED THE FUND'S PERFORMANCE DURING THE PERIOD, AND
WHAT INVESTMENT TECHNIQUES WERE USED TO ADDRESS THOSE CONDITIONS?

Over the last 12 months, the U.S. bond market exhibited moderate volatility. On
June 30, 1997, the yield on the 30-year Treasury Bond was 6.78%, compared to a
yield of 6.89% for the previous year. The 0.11% decrease in rates masked the
price movement during the 12-month period, as rates actually experienced an
<PAGE>
 
increase in the first two quarters of 1997. With the uncertainty reflecting the
direction of interest rates, we held the duration of the Fund within a
relatively tight range. The Fund's focus on duration, along with its sizable
positions in high-income producing corporate bonds, asset-backed securities, and
mortgages, all had a positive impact on performance.

WERE THERE ANY SHIFTS IN THE FUND'S PORTFOLIO HOLDINGS/SECTORS THAT HAD A
SIGNIFICANT IMPACT ON FUND PERFORMANCE?

There were no major shifts in portfolio holdings that significantly impacted
performance. However, we should note the performance of various sectors.
Corporates, mortgages, and asset-backed securities were important components of
the Fund's portfolio construction. Over the past 12 months, these sectors
performed very well relative to Treasuries. The best performing sector was
mortgages, largely due to strong price performance and high yields. The Fund's
holdings in this sector increased in both value and overall portfolio weighting.

WHAT IS OUR INTERMEDIATE- AND LONG-TERM OUTLOOK FOR THE FUND?

With slow economic growth and low inflation, we expect strength in the
bond market to continue over the intermediate term. Should economic growth be
stronger than expected, inflation concerns may reappear, causing higher interest
rates and lower bond prices. To help protect the Fund against potential price
volatility, we expect to maintain the Fund's duration at slightly below two
years.

Over the longer term, we anticipate continued growth in the economy but have
concerns regarding how long this expansion can last, especially with little to
no inflation. Credit excesses, profit disappointments, and the unpredictability
of foreign capital flows may cause short-term volatility in the bond market, but
over the long run, we continue to believe that fixed income investors will be
rewarded in terms of both total returns and income.

Item 15.  Indemnification
          ---------------

       Under Section 6.4 of Registrant's Master Trust Agreement, as amended, any
past or present Trustee or officer of Registrant (including persons who serve at
Registrant's request as directors, officers or trustees of another organization
in which Registrant has any interest as a shareholder, creditor or otherwise
(hereinafter referred to as a "Covered Person")), is indemnified to the fullest
extent permitted by law against liability and all expenses reasonably incurred
by him in connection with any action, suit or proceeding to which he may be a
party or otherwise involved by reason of his being or having been a Covered
Person.  This provision does not authorize indemnification when it is
determined, in the manner specified in the Master Trust Agreement, that a
Covered Person has not acted in good faith in the reasonable belief that his
actions were in or not opposed to the best interests of Registrant.  Moreover,
this provision does not authorize indemnification when it is determined, in the
manner specified in the Master Trust Agreement, that the Covered Person would
otherwise be liable to Registrant or its shareholders by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of his duties.
Expenses may be paid by Registrant in advance of the final disposition of any
action, suit or proceeding upon receipt of an undertaking by a Covered Person to
repay those expenses to Registrant in the event that it is ultimately determined
that indemnification of the expenses is not authorized under the Master Trust
Agreement and the Covered Person either provides security for such undertaking
or insures Registrant against losses from such advances or the disinterested
Trustees or independent legal counsel determines, in the manner specified in the
Master Trust Agreement, that there is reason to believe the Covered Person will
be found to be entitled to indemnification.

       Insofar as indemnification for liability arising under the Securities Act
of 1933, as amended (the "1933 Act"), may be permitted to Trustees, officers and
controlling persons of Registrant pursuant to the foregoing provisions, or
otherwise, Registrant has been advised that, in the opinion of the Securities
and Exchange Commission, such indemnification is against public policy as
expressed in the 1933 Act and is, therefore, unenforceable.  In the event that a
claim for indemnification against such liabilities (other than the payment by
Registrant of expenses incurred or paid by a Trustee, officer or controlling
person of Registrant in the successful defense of any action, suit or
proceeding) is asserted by such Trustee, officer or controlling person in
connection with the securities being registered, Registrant will, unless in the
opinion of its counsel the 

                                      C-1
<PAGE>
 
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the 1933 Act and will by governed by the
final adjudication of such issue.

     INVESTMENT MANAGEMENT AGREEMENT (this "Agreement"), dated _______________,
1997, between Sierra Trust Funds, a Massachusetts business trust, (the "Trust"),
on behalf of its series Short Term High Quality Bond Fund (the "Fund") and
Composite Research & Management Co., a Washington corporation (the "Manager").

                              W I T N E S S E T H
                              -------------------

     WHEREAS, the Trust is a diversified, open-end series management investment
company, registered under the Investment Company Act of 1940, as amended (the
"1940 Act"); and

     WHEREAS, the Fund, a separate series of the Trust, desires to retain the
Manager to render investment management services to the Fund, and the Manager is
willing to render such services;

     NOW, THEREFORE, in consideration of the premises and the mutual agreements
herein contained, the parties hereto agree as follows:

     Appointment.  The Fund hereby appoints the Manager to act as investment
     -----------                                                            
manager to the Fund for the period and on the terms set forth in this Agreement.
The Manager accepts such appointment and agrees to render the services herein
described, for the compensation herein provided.

     Management.  Subject to the supervision of the Board of Trustees of the
     ----------                                                             
Trust, the Manager shall manage the investment operations of the Fund and the
composition of the Fund's portfolio, including the purchase, retention and
disposition of securities therefor, in accordance with the Fund's investment
objectives, policies and restrictions as stated in the Prospectus and Statement
of Additional Information (as such terms are hereinafter defined) and
resolutions of the Trust's Board of Trustees and subject to the following
understandings:


           The Manager shall provide supervision of the Fund's investments,
     furnish a continuous investment program for the Fund's portfolio and
     determine from time to time what securities will be purchased, retained, or
     sold by the Fund, and what portion of the assets will be invested or held
     as cash.
<PAGE>
 
     The Manager shall use reasonable care and judgment in the management of the
Fund's portfolio.


     The Manager, in the performance of its duties and obligations under this
Agreement, shall act in conformity with the Declaration of Trust (as hereinafter
defined) of the Trust and the investment policies of the Fund as determined by
the Board of Trustees of the Trust and set forth in the Prospectus and Statement
of Additional Information.


     The Manager shall determine the securities to be purchased or sold by the
Fund and shall place orders for the purchase and sale of portfolio securities
pursuant to its determinations with brokers or dealers selected by the Manager.
In executing portfolio transactions and selecting brokers or dealers, the
Manager shall use its best efforts to seek on behalf of the Fund the best
overall terms available.  In assessing the best overall terms available for any
transaction, the Manager may consider all factors it 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.  In evaluating the best overall terms available, and in
selecting the broker or dealer to execute a particular transaction, the Manager
also may consider the brokerage and research services (as those terms are
defined in Section 28(e) of the Securities Exchange Act of 1934, as amended)
provided to the Fund and/or other accounts over which the Manager exercises
investment discretion.  The Manager 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 the
transaction if the Manager 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 that particular
transaction or in terms of the overall responsibilities of the Manager to the
Fund and/or other accounts over which the Manager exercises investment
discretion.


     On occasions when the Manager deems the purchase or sale of a security to
be in the best interest of the Fund as well as other fiduciary accounts for
which it has investment responsibility, the Manager, to the extent permitted by
applicable laws and regulations, may aggregate the securities to be so sold or
purchased in 

                                       2

     order to obtain the best execution, most favorable net price or lower
     brokerage commissions.

     sub-advisor, if any, under its investment sub-advisory agreement,

     investment objective(s) and policies and the Fund's investment performance.

          securities or cash issued or paid in connection with any
          reorganization, recapitalization, merger, consolidation, split-up of
          shares, change of par value, conversion or otherwise, and will deposit
          any such securities in accordance with the terms of any reorganization
          orprotective plan. Without instructions, Custodian is authorized to

          definitive form, to effect an exchange of shares when the par value of
          the stock is changed, and upon receiving payment therefor, to

          In accordance with such instructions, Custodian will pay for out of
monies held for the account of Fund, but only insofar as monies are available
therein for such purpose, and receive the portfolio securities so purchased by

amount payable upon such purchase.  Such payment will be made only upon receipt
by Custodian of the securities so purchased in form for transfer satisfactory to
Custodian.

          Guaranty and Trust Company (MGTC), Chemical Bank (CB), and Bankers
          Trust Company (BT) for variable rate securities and Custodian will be
          responsible to the Fund to the same extent those entities are
          responsible to Custodian. The Fund shall be entitled to review
          Custodian's contracts with BONY, MGTC, CB, and BT.

    T. Accounts and Records Property of Fund
       -------------------------------------
       Custodian acknowledges that all of the accounts and records maintained by
       Custodian pursuant to this Agreement are the property of Fund, and will
       be made available to

                                      -9-
<PAGE>
 
       Fund for inspection or reproduction within a reasonable period of time,
       upon demand. Custodian will assist Fund's independent auditors, or upon
       approval of Fund, or upon demand, any regulatory body having jurisdiction
       over the Fund or Custodian, in any requested review of Fund's accounts
       and records but shall be reimbursed for all expenses and employee time
       invested in any such review outside of routine and normal periodic
       reviews.

   U.  Adoption of Procedures
       ----------------------
       Custodian and Fund may from time to time adopt procedures as they agree
       upon, and Custodian may conclusively assume that no procedure approved by
       Fund, or directed by Fund, conflicts with or violates any requirements of
       its prospectus, "Articles of Incorporation," Bylaws, or any rule or
       regulation of any regulatory body or governmental agency. Fund will be
       responsible to notify Custodian of any changes in statutes, regulations,
       rules or policies which might necessitate changes in Custodian's
       responsibilities or procedures.

   V.  Overdrafts
       ----------
       If Custodian shall in its sole discretion advance funds to the account of
       the Fund which results in an overdraft because the monies held by
       Custodian on behalf of the Fund are insufficient to pay the total amount
       payable upon a purchase of securities as specified in a Fund's
       instructions or for some other reason, the amount of the overdraft shall
       be payable by the Fund to Custodian upon demand and shall bear an
       interest rate determined by Custodian from the date advanced until the
       date of payment. Custodian shall have a lien on the assets of Fund in the
       amount of any outstanding overdraft.

4. INSTRUCTIONS.
   -------------

   A.  The term "instructions," as used herein, means written or oral
       instructions to Custodian from a designated representative of Fund.
       Certified copies of resolutions of the Board of Directors of Fund naming
       one or more designated representatives to give instructions in the name
       and on behalf of Fund, may be received and accepted from time to time by
       Custodian as conclusive evidence of the authority of any designated
       representative to act for Fund and may be considered to be in full force
       and effect (and Custodian will be fully protected in acting in reliance
       thereon) until receipt by Custodian of notice to the contrary. Unless the
       resolution delegating authority to any person to give instructions
       specifically requires that the approval of anyone else will first have
       been obtained, Custodian will be under no obligation to inquire into the
       right of the person giving such instructions to do so. Notwithstanding
       any of the foregoing provisions of this Section 4. no authorizations or
       instructions received by Custodian from Fund, will be deemed to authorize
       or permit any director, trustee, officer, employee, or agent of Fund to
       withdraw any of the securities or 

                                      -10-
<PAGE>
 
       similar investments of Fund upon the mere receipt of such authorization
       or instructions from such director, trustee, officer, employee or agent.

   B.  No later than the next business day immediately following each oral
       instruction, Fund will send Custodian written confirmation of such oral
       instruction. At Custodian's sole discretion, Custodian may record on
       tape, or otherwise, any oral instruction whether given in person or via
       telephone, each such recording identifying the parties, the date and the
       time of the beginning and ending of such oral instruction.

5. LIMITATION OF LIABILITY OF CUSTODIAN.
 
   A.  Custodian shall hold harmless and indemnify Fund from and against any
       loss or liability arising out of Custodian's negligence or bad faith.
       Custodian shall not be liable for consequential damages, special, or
       punitive damages. Custodian may request and obtain the advice and opinion
       of counsel for Fund, or of its own counsel with respect to questions or
       matters of law, and it shall be without liability to Fund for any action
       taken or omitted by it in good faith, in conformity with such advice or
       opinion. If Custodian reasonably believes that it could not prudently act
       according to the instructions of the Fund or the Fund's counsel, it may
       in its discretion, with notice to the Fund, not act according to such
       instructions.

   B.  Custodian may rely upon the advice of Fund and upon statements of Fund's
       accountants and other persons believed by, it in good faith, to be expert
       in matters upon which they are consulted, and Custodian shall not be
       liable for any actions taken, in good faith, upon such statements.

   C.  If Fund requires Custodian in any capacity to take, with respect to any
       securities, any action which involves the payment of money by it, or
       which in Custodian's opinion might make it or its nominee liable for
       payment of monies or in any other way, Custodian, upon notice to Fund
       given prior to such actions, shall be and be kept indemnified by Fund in
       an amount and form satisfactory to Custodian against any liability on
       account of such action.

   D.  Custodian shall be entitled to receive, and Fund agrees to pay Custodian,
       on demand, reimbursement for such cash disbursements, costs and expenses
       as may be agreed upon from time to time by Custodian and Fund.

   E.  Custodian shall be protected in acting as custodian hereunder upon any
       instructions, advice, notice, request, consent, certificate or other
       instrument or paper reasonably appearing to it to be genuine and to have
       been properly executed and shall, unless otherwise specifically provided
       herein, be entitled to receive as conclusive proof of any fact or matter
       required to be ascertained from Fund hereunder, a certificate signed by
       the Fund's President, or other officer specifically authorized for such
       purpose.

                                      -11-
<PAGE>
 
   F.  Without limiting the generality of the foregoing, Custodian shall be
       under no duty or obligation to inquire into, and shall not be liable for:
 
       1. The validity of the issue of any securities purchased by or for Fund,
          the legality of the purchase thereof or evidence of ownership required
          by Fund to be received by Custodian, or the propriety of the decision
          to purchase or amount paid therefor;
       2. The legality of the sale of any securities by or for Fund, or the
          propriety of the amount for which the same are sold;
       3. The legality of the issue or sale of any shares of the Capital Stock
          of Fund, or the sufficiency of the amount to be received therefor;
       4. The legality of the repurchase or redemption of any Fund Shares, or
          the propriety of the amount to be paid therefor; or
       5. The legality of the declaration of any dividend by Fund, or the
          legality of the issue of any Fund Shares in payment of any stock
          dividend.

   G.  Custodian shall not be liable for, or considered to be Custodian of, any
       money represented by any check, draft, wire transfer, clearing house
       funds, uncollected funds, or instrument for the payment of money received
       by it on behalf of the Fund, until Custodian actually receives such
       money, provided only that it shall advise Fund promptly if it fails to
       receive any such money in the ordinary course of business, and use its
       best efforts and cooperate with Fund toward the end that such money shall
       be received.

   H.  Custodian shall not be responsible for loss occasioned by the acts,
       neglects, defaults or insolvency of any broker, bank, trust company, or
       any other person with whom Custodian may deal in the absence of
       negligence, or bad faith on the part of the Custodian.

   I.  Notwithstanding anything herein to the contrary, Custodian may, and with
       respect to any foreign subcustodian appointed under Section 3.S.2. must,
       provide the Fund for its approval, agreements with banks or trust
       companies which will act as subcustodians for Fund pursuant to Section
       3.S of this Agreement.

6. COMPENSATION.  Fund will pay Custodian such compensation as is stated in the
   -------------                                                               
   Fee   Schedule attached hereto as Exhibit B which may be changed from time to
   time as agreed to in writing by Custodian and Fund.  Custodian may charge
   such compensation against monies held by it for the account of Fund.
   Custodian will also be entitled, notwithstanding the provisions of Sections
   5.C. or 5.D. hereof, to charge against any monies held by it for the account
   of Fund the amount of any loss, damage, liability, advance, or expense for
   which it shall be entitled to reimbursement under the provisions of this
   Agreement including fees or expenses due to Custodian for other services
   provided to the Fund by the Custodian.

                                      -12-
<PAGE>
 
7. TERMINATION.  Either party to this Agreement may terminate the same by notice
   ------------                                                                 
   in   writing, delivered or mailed, postage prepaid, to the other party hereto
   and received not less than ninety (90)  days prior to the date upon which
   such termination will take effect.  Upon termination of this Agreement, Fund
   will pay to Custodian such compensation for its reimbursable disbursements,
   costs and expenses paid or incurred to such date and Fund will use its best
   efforts to obtain a successor custodian.  Unless the holders of a majority of
   the outstanding shares of "Capital Stock" of Fund vote to have the
   securities, funds and other properties held under this Agreement delivered
   and paid over to some other person, firm or corporation specified in the
   vote, having not less than Two Million Dollars ($2,000,000) aggregate
   capital, surplus and undivided profits, as shown by  its last published
   report, and meeting such other qualifications for custodian as set forth in
   the Bylaws of Fund, the Board of Directors of Fund will, forthwith upon
   giving or receiving notice of termination of this Agreement, appoint as
   successor custodian a bank or trust company having such qualifications.
   Custodian will, upon termination of this Agreement, deliver to the successor
   custodian so specified or appointed, at Custodian's office, all securities
   then held by Custodian hereunder, duly endorsed and in form for transfer, all
   funds and other properties of Fund deposited with or held by Custodian
   hereunder, or will cooperate in effecting changes in book-entries at the
   Depository Trust Company or in the Treasury/Federal Reserve Book-Entry System
   pursuant to 31 CFR Sec. 306.118.  In the event no such vote has been adopted
   by the stockholders of Fund and no written order designating a successor
   custodian has been delivered to Custodian on or before the date when such
   termination becomes effective, then Custodian will deliver the securities,
   funds and properties of Fund to a bank or trust company at the selection of
   Custodian and meeting the qualifications for custodian, if any, set forth in
   the Bylaws of Fund and having not less than Two Million Dollars ($2,000,000)
   aggregate capital, surplus and undivided profits, as shown by its last
   published report.  Upon either such delivery to a successor custodian,
   Custodian will have no further obligations or liabilities under this
   Agreement.  Thereafter such bank or trust company will be the successor
   custodian under this Agreement and will be entitled to reasonable
   compensation for its services.  In the event that no such successor custodian
   can be found, Fund will submit to its shareholders, before permitting
   delivery of the cash and securities owned by Fund to anyone other  than a
   successor custodian, the question of whether Fund will be liquidated or
   function without a custodian.  Notwithstanding the foregoing requirement as
   to delivery upon termination of this  Agreement, Custodian may make any other
   delivery of the securities, funds and property of Fund which is permitted by
   the Investment Company Act of 1940, Fund's Certificate of Incorporation and
   Bylaws then in effect or apply to a court of competent jurisdiction for the
   appointment of a successor custodian.

8. NOTICES.  Notices, requests, instructions and other writings received by Fund
   --------                                                                     
   at 9301 Corbin Avenue, Mail Stop: No. 321 Northridge, California, 91324 or at
   such other address as Fund may have designated to Custodian in writing, will
   be deemed to have been properly given to Fund hereunder; and notices,
   requests, instructions and other writings received by Custodian at its
   offices at 127 West 10th Street, Kansas City, Missouri 64105, or to such

                                      -13-

   other address as it may have designated to Fund in writing, will be deemed to
   have been properly given to Custodian hereunder.

       requests such information pursuant to the Shareholder Communications Act
       of 1985 for the specific purpose of direct communications between such
       issuer and Fund unless the Fund directs the Custodian otherwise.
 
   H.  This Agreement may not be assigned by either party without prior written
       consent of the other party.

   I.  If any provision of the Agreement, either in its present form or as
       amended from time to time, limits, qualifies, or conflicts with the
       Investment Company Act of 1940, as amended, and the rules and regulations
       promulgated thereunder, such statutes, rules and regulations shall be
       deemed to control and supercede such provision without nullifying or
       terminating the remainder of the provisions of this Agreement.

             bank credit rate (see below) applied to average custody collected
             cash balances for the month. Balance credits can be used to offset
             fees. Any credits in excess of fees will be carried forward from
             month to month through the end of the calendar year. For
             calculation purposes, IFTC uses an actual/actual basis.

          Note:  The bank credit rate is the equivalent to the lesser of:
                 The average 91-day Treasury Bill discount rate for the month
            or
                 The average Federal Funds rate for the month less 50 basis
                 points.

                                                            (SIERRA TRUST FUNDS)


                              SIERRA TRUST FUNDS

                               MULTI-CLASS PLAN

                    Effective Date (_______________, 1997)


     WHEREAS, the Board of Trustees of Sierra Trust Funds (the "Trust") have
considered the following Multi-Class Plan (the "Plan") under which the Trust may
offer multiple classes of shares of its now existing and hereafter created
series pursuant to Rule 18f-3 under the Investment Company Act of 1940, as
amended (the "1940 Act"); and

     WHEREAS, a majority of the Trustees of the Trust and a majority of the
Trustees who are not interested persons of the Trust ("Independent Trustees")
have found the Plan, as proposed, including the expense allocations thereunder,
to be in the best interests of each class individually and of each Fund (as
defined below) and the Trust as a whole;

     NOW, THEREFORE, the Trust hereby approves and adopts the following Plan
pursuant to Rule 18f-3(d) under the 1940 Act.


     FEATURES OF THE CLASSES

     Each now existing and hereafter created series (each a "Fund") of the Trust
is authorized to issue from time to time its shares of beneficial interest in
four classes:  Class A shares, Class B shares, Class I shares, and Class S
shares.  Each class is subject to such investment minimums and other conditions
of eligibility as are set forth in the Trust's prospectus or prospectuses as
from time to time in effect (together with all relevant Statements of Additional
Information, the "Prospectus").  Each Fund offers such classes of shares to such
classes of persons as are set forth in the Prospectus.

     Shares of each class of a Fund shall represent an equal pro rata interest
in such Fund and, generally, shall have identical voting, dividend, liquidation,
and other rights, preferences, powers, restrictions, limitations, qualifications
and terms and conditions, except that: (a) each class shall have a different
designation; (b) each class of shares shall bear any Class Expenses, as defined
in Section 4 below; and (c) each class shall have separate voting rights on any
matter submitted to shareholders in which the interests of one class differ from
the interests of any other class and shall have exclusive voting rights on any
matter submitted to shareholders that relates solely to that class.
<PAGE>
 
     In addition, Class A, Class B, Class I, and Class S shares shall have the
features described in Sections 2, 3, 4, 5, 6 and 7 below.  These features are
subject to change, to the extent permitted by law and by the Declaration of
Trust and By-laws of the Trust, by action of the Board of Trustees of the Trust.

     SALES CHARGE STRUCTURE

     (a)  Initial Sales Charge.  Class A shares of the "Non-Money Funds", which
          --------------------                                                 
are the Funds other than California Money Fund (the "Money Fund"), are offered
at a public offering price that is equal to their net asset value ("NAV") plus
an initial sales charge expressed as a percentage of the NAV per share, as
described in the Prospectus.  Class A shares of the Money Fund are offered at
their NAV, without an initial sales charge.

     The initial sales charge on Class A shares are subject to reduction or
waiver as permitted by Rule 22d-1 under the 1940 Act, as described in the
Prospectus.

     The exact terms and conditions of any initial sales charge applicable to
Class A shares, which may vary among Funds, will be as described in the
Prospectus.

     Class B, Class I and Class S shares of the Funds are offered at their NAV,
without an initial sales charge.

     (b)  Contingent Deferred Sales Charge.  A contingent deferred sales charge
          --------------------------------                                     
(a "CDSC") may be imposed on Class A, Class B or Class S shares under certain
circumstances, as described in the Prospectus.  However, no CDSC is imposed if
the shares redeemed have been acquired through the reinvestment of net
investment income or capital gains distributions or if the amount redeemed is
derived from increases in the value of the account above the amount of purchase
payments subject to a CDSC.  In determining whether a CDSC is payable, a Fund
will first redeem shares not subject to a CDSC.  Thereafter, to determine the
applicability and rate of any CDSC, it will be assumed that shares representing
the reinvestment of dividends and capital gain distributions are redeemed first
and shares held for the longest period of time are redeemed next.

     Class A shares of Non-Money Funds that are purchased at no initial sales
charge or a reduced initial sales charge and that are redeemed within two years
of their purchase may, under certain circumstances, be subject to a CDSC of up
to 1% of the redemption amount to which the CDSC applies, with the percentage
declining eventually to zero the longer the shares are held, as described in the
Prospectus.

     Class B shares that are redeemed within up to six years from purchase are
subject to a CDSC of up to 5% of the redemption amount to which the CDSC
applies, with the percentage declining eventually to zero the longer the shares
are held, as described in the Prospectus.

     Class S shares that are redeemed within up to six years from purchase are
subject to a 

                                       2
<PAGE>
 
CDSC of up to 5% of the redemption amount to which the CDSC applies, with the
percentage declining eventually to zero the longer the shares are held, as
described in the Prospectus.

     As permitted by Rule 6c-10 under the 1940 Act and as described in the
Prospectus, the CDSC otherwise applicable to Class A, Class B and Class S shares
is subject to reduction or waiver in connection with particular classes of
transactions provided the conditions in Rule 22d-1 under the 1940 Act are
satisfied.

     The exact terms and conditions of any CDSC applicable to Class A, Class B
or Class S shares, which may vary among Funds, are as described in the
Prospectus.

     Class I shares of each Fund are not subject to a CDSC.


     SERVICE, DISTRIBUTION AND ADMINISTRATIVE FEES

     (a)  Service and Distribution Fees.  Class A, Class B and Class S shares 
          -----------------------------
pay Composite Funds Distributor, Inc. (the "Distributor") fees for services
rendered and expenses borne in connection with personal services rendered to
shareholders of that class and the maintenance of shareholder accounts ("Service
Fees"). Class A, Class B and Class S shares of each Fund pay a Service Fee of up
to 0.25% per annum of the average daily net assets of such Fund attributable to
such class, as described in the Prospectus. In addition, Class B and Class S
shares pay the Distributor fees in connection with the distribution of shares of
such class ("Distribution Fees"). Class B and Class S shares of each Fund pay a
Distribution Fee of up to 0.75% per annum of the average daily net assets of
such Fund attributable to such class, as described in the Prospectus. Class A,
Class B and Class S Service Fees and Class B and Class S Distribution Fees 
("12b-1 Fees") are paid pursuant to plans adopted for each class pursuant to
Rule 12b-1 under the 1940 Act.

     (b)  Administration Fees.  Each Fund pays Composite Research & Management
          -------------------                                                 
Co. fees pursuant to an investment management agreement, which may be amended or
replaced from time to time, for investment management services; a portion of the
fee is allocated to Murphey Favre Securities Services, Inc. for administrative
services to provide or procure such services as custody, accounting, legal and
printing services (the portion of the fee allocated to such administrative
services, the "Administration Fees").  Class A, Class B, Class I and Class S
shares of each Fund initially will pay their respective allocable share of
Administration Fees incurred by such Fund (currently at the rate of .15% per
annum of the average daily net assets of such Fund), based on the average daily
net asset value of such Fund attributable to such class.

     (c)  Transfer Agency Fees.  Each class of shares of each Fund pays Murphey
          --------------------                                                 
Favre Securities Services, Inc. fees pursuant to a Shareholder Services
Contract, which may be amended or replaced from time to time, for services to
provide or procure such services as transfer agency services (the "Transfer
Agent Fees").  Class A, Class B, Class I and Class S shares of each Fund

                                       3
<PAGE>
 
initially will pay their respective Transfer Agent Fees (for most services,
currently on a per account basis at different rates for different classes of
different Funds), based on the incurrence of Transfer Agent Fees attributable in
the aggregate to each such class of such Fund.


     ALLOCATION OF INCOME AND EXPENSES

     (a)  Class A, Class B, Class I and Class S shares pay the expenses
associated with their different distribution and shareholder servicing
arrangements. Each class pays their respective allocable share of Administration
Fees. Each class pays their respective Transfer Agent Fees. Each class may, at
the Trustees' discretion, also pay a different share of other expenses (together
with 12b-1 Fees, Administration Fees and Transfer Agent Fees, "Class Expenses"),
not including advisory fees or other expenses related to the management of the
Trust's assets, if these expenses are actually incurred in a different amount by
that class, or if the class receives services of a different kind or to a
different degree than other classes.

     (b)  The gross income of each Fund generally shall be allocated to each
class on the basis of net assets. To the extent practicable, certain expenses
(other than Class Expenses as defined above, which shall be allocated more
specifically) shall be subtracted from the gross income on the basis of the net
assets of each class of the Fund. These expenses include:

                (1)   Expenses incurred by the Trust (including, but not limited
                      to, fees of Trustees, insurance and legal counsel) not
                      attributable to a particular Fund or to a particular class
                      of shares of a Fund ("Trust Expenses"); and

                (2)   Expenses incurred by a Fund not attributable to any
                      particular class of the Fund's shares (for example,
                      advisory fees, custodial fees or other expenses relating
                      to the management of the Fund's assets) ("Fund Expenses").

          Expenses of a Fund shall be apportioned to each class of shares
depending on the nature of the expense item. Trust Expenses and Fund Expenses
shall be allocated among the classes of shares based on their relative net asset
values in relation to the net asset value of the Trust or the Fund, as
appropriate. Class Expenses shall be allocated to the particular class to which
they are attributable. In addition, certain expenses may be allocated
differently if their method of imposition changes. Thus, if a Class Expense can
no longer be attributed to a class, it shall be charged to a Fund for allocation
among classes, as determined by the Board of Trustees. Any additional Class
Expenses not specifically identified above which are subsequently identified and
determined to be properly allocated to one class of shares shall not be so
allocated until approved by the Board of Trustees of the Trust in light of the
requirements of the 1940 Act and the Internal Revenue Code of 1986, as amended
(the "Code").

     EXCHANGE PRIVILEGES

     Shareholders may exchange (i) shares of one class of a Fund for shares of
the same class offered by another Fund or by certain other mutual funds from
time to time advised by Composite Research & Management Co. and (ii) Class B
shares of a Fund for Class S shares, or Class S shares of a Fund for Class B
shares, offered by another Fund or by certain other mutual funds from time to
time advised by Composite Research & Management Co, as described in the
Prospectus and provided that the exchange is made in states where the shares
being acquired upon exchange are properly registered.  An exchange shall be made
at net asset value without the imposition of any CDSC upon the exchange and,
except as otherwise described in the Prospectus, without the imposition of any
sales charge upon the exchange.  The applicability and rate of any CDSC with
respect to a subsequent redemption of shares acquired upon an exchange will be
determined as described in the Prospectus.  The exact terms and conditions of an
exchange, which may vary among the Funds, will be as described in the
Prospectus.


     CONVERSION FEATURES

     Class B and Class S shares of each Fund will convert, after they are held
for approximately eight years from purchase, at net asset value without the
imposition of any CDSC or sales charge upon the conversion, into Class A shares
of the same Fund, which thereafter will be subject to the lower fees charged to
Class A shares.  The exact terms and conditions of a conversion will be as
described in the Prospectus.  No other conversion features exist between classes
of shares of the Funds.


     SPECIAL PROVISIONS FOR OUTSTANDING SHARES

     In the case of Class A, Class B, Class I and Class S shares which are
outstanding on the effective date of the Plan, or issued upon any subsequent
exchange thereof, the terms and conditions of any CDSC, exchange or conversion
features applicable to such shares shall be no less favorable than the ones
applicable to the Class A, Class B, Class I and Class S shares of the respective
Fund, as described in the prospectus or prospectuses of the Funds as in effect
from time to time prior to the effective date of the Plan.  In addition, for
purposes of calculating any CDSC or making any conversion, shares issued in
connection with the Agreement and Plan of Reorganization between the Short Term
Global Government Fund and the Short Term High Quality Bond Fund or any other
acquisition of the assets of a mutual fund shall be deemed to have been
purchased on the same dates as the corresponding shares of the acquired mutual
fund.
