Dear Sierra Prime Income Fund Shareholder:

Because of the unique nature of the senior loans that the Sierra Prime Income
Fund invests in, sales of Fund shares are possible through a tender offer which
is expected to be made available once per quarter. The Fund continues to meet
its objective of a relatively stable Net Asset Value ("NAV") and is expected to

3-month T-Bill, and 13 basis points over the yield on a 30-year Treasury Bond.1/


Sierra continues to stress the benefits of a long-term investment perspective,
but in addition strives to offer high levels of customer service to our
shareholders. We understand that financial emergencies arise, and therefore we
periodically provide liquidity of the shares of the Sierra Prime Income Fund.
The Fund is offering to purchase 161,925 shares of its issued and outstanding
Class A Shares Common Shares at the closing "NAV" at 2:00 P.M. Pacific Standard
Time on January 9, 1998. This tender offer period will begin on December 10,

 The Offer is not being made to, nor will tenders be accepted from or on behalf
           of, holders of Class A Common Shares in any jurisdiction in

               OF ITS ISSUED AND OUTSTANDING CLASS A COMMON SHARES
                          AT NET ASSET VALUE PER SHARE

- --------------------------------------------------------------------------------

         Sierra Prime Income Fund (the "Fund") is offering to purchase 161,925
of its issued and outstanding Class A common shares of beneficial interest, no
par value ("Class A Common Shares"), at a price equal to their net asset value
("NAV") determined as of 2:00 PM Pacific Standard Time on January 9, 1998, the
Expiration Date, unless extended, upon the terms and conditions set forth in the
Offer to Purchase dated December 10, 1997 and the related Letter of Transmittal
(which together constitute the "Offer"). The NAV on December 1, 1997 was $10.00
per Class A Common Share. The purpose of the Offer is to provide liquidity to
shareholders since the Fund is unaware of any secondary market which exists for
the Class A Common Shares. The Offer is not conditioned upon the tender of any
minimum number of Class A Common Shares, but is subject to certain conditions as
set forth in the Offer.

         If more than 161,925 Class A Common Shares are duly tendered prior to
the expiration of the Offer, the Fund presently intends to, assuming no changes
in the factors originally considered by the Board of Trustees when it determined
to make the Offer and the other conditions set forth in the Offer, but is under
no obligation to, extend the Offer period, if necessary, and increase the number
of Class A Common Shares that the Fund is offering to purchase to an amount
which it believes will be sufficient to accommodate the excess Class A Common

investment company organized as a Massachusetts business trust (the "Fund"), is
offering to purchase up to 161,925 of its Class A Common Shares of beneficial
interest, with no par value ("Class A Common Shares"), for cash at a price (the
"Purchase Price") equal to their net asset value ("NAV") determined as of 2:00
PM Pacific Standard Time on the Expiration Date (as defined herein), upon the
terms and conditions set forth in this Offer to Purchase and the related Letter
of Transmittal (which together constitute the "Offer"). The Offer is scheduled
to terminate as of 6:00 PM Pacific Standard Time on January 9, 1998, unless

161,925 Class A Common Shares (or such greater number of Class A Common Shares
sought) on a pro rata basis.

EXHIBIT A:        UNAUDITED FINANCIAL STATEMENTS FOR THE PERIOD ENDED 
                  SEPTEMBER 30, 1997

         1.  PRICE; NUMBER OF CLASS A COMMON SHARES.

         The Fund will, upon the terms and subject to the conditions of the
Offer, accept for payment (and thereby purchase) 161,925 or such lesser number
of its issued and outstanding Class A Common Shares which are properly tendered
(and not withdrawn in accordance with Section 4 prior to 6:00 PM Pacific
Standard Time on January 9, 1998 (such time and date being hereinafter called
the "Initial Expiration Date"). The Fund reserves the right to extend the Offer.
See Section 16. The later of the Initial Expiration Date or the latest time and
date to which the Offer is extended is hereinafter called the "Expiration Date."
The Purchase Price of the Class A Common Shares will be their NAV determined as
of 2:00 PM Pacific Standard Time on the Expiration Date. Holders of Class A
Common Shares may tender or withdraw previously tendered shares to the
Administrator at the address set forth in page 2 of this Offer to Purchase by
written telegraphic, telex or facsimile transmission of a notice of withdrawal
prior to the Expiration Date. The NAV on December 1, 1997 was $10.00 per Class A
Common Share. You can obtain current NAV quotations from Sierra Shareholder
Services by calling (800) 222-5852 between the hours of 6:00 AM and 6:00 PM
Pacific Standard Time, Monday through Friday and 6:00 AM and 3:00 PM Pacific
Standard Time on Saturday, except holidays. Shareholders tendering Class A
Common Shares shall be entitled to receive all dividends declared on or prior to
settlement following the Expiration Date, but not yet paid, on Class A Common
Shares tendered pursuant to the Offer. See Section 9. The Fund will not pay
interest on the Purchase Price under any circumstances. An Early Withdrawal
Charge may be imposed on certain Class A Common Shares accepted for payment that
have been held for less than two years. See Section 3.

         The Offer is being made to all shareholders of the Fund and is not
conditioned upon any minimum number of Class A Common Shares being tendered. If
the number of Class A Common Shares properly tendered prior to the Expiration
Date and not withdrawn is less than or equal to 161,925 Class A Common Shares
(or such greater number of Class A Common Shares as the Fund may elect to
purchase pursuant to the Offer), the Fund will upon the terms and subject to the
conditions of the Offer, purchase at NAV all Class A Common Shares so tendered.
If more than 161,925 Class A Common Shares are duly tendered prior to the
expiration of the Offer and not withdrawn, the Fund presently intends to,
subject to the condition that there have been no changes in the factors
originally considered by the Board of Trustees when it determined to make the
Offer and the other conditions set forth in Section 6, but is not obligated to,
extend the Offer period, if necessary, and increase the number of Class A Common
Shares that the Fund is offering to purchase to an amount which it believes will
be sufficient to accommodate the excess Class A Common Shares tendered as well
as any Class A Common Shares tendered during the extended Offer period or
purchase 161,925 Class A Common Shares (or such greater number of Class A Common
Shares sought) on a pro rata basis.

         On December 1, 1997, there were approximately 809,624.934 Class A
Common Shares issued and outstanding and there were approximately 341 holders of
record of Class A Common Shares. The Fund has been advised that no trustees,
officers or affiliates of the Fund intend to tender any Class A Common Shares
pursuant to the Offer.

         The Fund reserves the right, in its sole discretion, at any time or
from time to time, to extend the period of time during which the Offer is open
by giving oral or written notice of such extension to the Administrator and
making a public announcement thereof. See Section 16. There can be no assurance,
however, that the Fund will exercise its right to extend the Offer. If the Fund
decides, in its sole discretion, to increase (except for any increase not in
excess of 2% of the outstanding Class A Common Shares) or decrease the number of
Class A Common Shares being sought and, at the time that notice of such increase
or decrease is first published, sent or given to holders of Class A Common
Shares in the manner specified below, the Offer is scheduled to expire at any
time earlier than the tenth business day from the date that such notice is first
so published, sent or given, the Offer will be extended at least until the end
of such ten business day period.

         2. PROCEDURE FOR TENDERING CLASS A COMMON SHARES.

         Proper Tender of Class A Common Shares. Except as otherwise set forth
under the heading "Procedures for Authorized Dealers" below, for Class A Common
Shares to be properly tendered pursuant to the Offer, a properly completed and
duly executed Letter of Transmittal (or manually signed facsimile thereof) with
any required signature guarantees and any other documents required by the Letter
of Transmittal, must be received on or before the Expiration Date by the
Administrator at its address set forth on page 2 of this Offer to Purchase.


                                        4

<PAGE>   5
         It is a violation of Section 14(e) of the Securities and Exchange Act
of 1934 (the "Exchange Act"), and Rule 14e-4 promulgated thereunder, for a
person to tender Class A Common Shares in a partial tender offer for such
person's own account unless at the time of tender and until such time as the
securities are accepted for payment the person so tendering has a net long
position equal to or greater than the amount tendered in (i) the Class A Common
Shares and will deliver or cause to be delivered such shares for purposes of
tender to the Fund prior to or on the Expiration Date, or (ii) an equivalent
security and, upon the acceptance of his or her tender will acquire the Class A
Common Shares by conversion, exchange, or exercise of such equivalent security
to the extent required by the terms of the Offer, and will deliver or cause to
be delivered the Class A Common Shares so acquired for the purpose of tender to
the Fund prior to or on the Expiration Date.

         Section 14(e) and Rule 14e-4 provide a similar restriction applicable
to the tender or guarantee of a tender on behalf of another person.

         The acceptance of Class A Common Shares by the Fund for payment will
constitute a binding agreement between the tendering shareholder and the Fund
upon the terms and subject to the conditions of the Offer, including the
tendering shareholder's representation that (i) such shareholder has a net long
position in the Class A Common Shares being tendered within the meaning of Rule
14e-4 promulgated under the Exchange Act and (ii) the tender of such Class A
Common Shares complies with Rule 14e-4.

         Signature Guarantees and Method of Delivery. Signatures on the Letter
of Transmittal are not required to be guaranteed unless (1) the proceeds for the
tendered Class A Common Shares will amount to more than $50,000, (2) the Letter
of Transmittal is signed by someone other than the registered holder of the
Class A Common Shares tendered therewith, or (3) payment for tendered Class A
Common Shares is to be sent to a payee other than the registered owner of such
Class A Common Shares and/or to an address other than the registered address of
the registered owner of the Class A Common Shares. In those instances, all
signatures on the Letter of Transmittal must be guaranteed by a member firm of a
national securities exchange or a commercial bank or trust company having an
office, branch or agency in the United States (an "Eligible Institution"). If
Class A Common Shares are registered in the name of a person or persons other
than the signer of the Letter of Transmittal or (a) if payment is to be made to
or (b) unpurchased Class A Common Shares are to be registered in the name of any
person other than the registered owner, then the Letter of Transmittal must be
endorsed or accompanied by appropriate authorizations, in either case signed
exactly is such name or names as appear on the registration of the Class A
Common Shares with the signatures on the authorizations guaranteed by an
Eligible Institution. See Instructions 1 and 5 of the Letter of Transmittal.

         Payment for Class A Common Shares tendered and accepted for payment
pursuant to the Offer will be made only after receipt by the Administrator on or
before the Expiration Date of a properly completed and duly executed Letter of
Transmittal (or manually signed facsimile thereof) and any other documents
required by the Letter of Transmittal.

         THE METHOD OF DELIVERY OF ANY DOCUMENTS IS AT THE ELECTION AND RISK OF
THE PARTY TENDERING CLASS A COMMON SHARES. IF DOCUMENTS ARE SENT BY MAIL, IT IS
RECOMMENDED THAT THEY BE SENT BY REGISTERED MAIL, PROPERLY INSURED, WITH RETURN
RECEIPT REQUESTED.

         Procedures for Authorized Dealers. If you are an Authorized Dealer, in
order for you to tender any Class A Common Shares pursuant to the Offer, you may
place a confirmed wire order with First Data Investor Services Group, Inc.
("First Data" or the "Transfer Agent"). All confirmed wire orders used to tender
Class A Common Shares pursuant to this Offer must be placed on the Expiration
Date only (wire orders placed on any other date will not be accepted by the
Fund). Class A Common Shares tendered by a wire order are deemed to be tendered
when the Transfer Agent receives the order but subject to the condition
subsequent that the settlement instructions, including (with respect to tendered
Class A Common Shares for which the Authorized Dealer is not the registered
owner) a properly completed and duly executed Letter of Transmittal (or manually
signed facsimile thereof), any other documents required by the Letter of
Transmittal, are received by the Transfer Agent.

         Determinations of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of tenders will be
determined by the Fund, in its sole discretion, whose determination shall be
final and binding. The Fund reserves the absolute right to reject any or all
tenders determined by it not to be in appropriate form or the

                                        5

<PAGE>   6
acceptance of or payment for which may, in the opinion of the Fund's counsel, be
unlawful. The Fund also reserves the absolute right to waive any of the
conditions of the Offer or any defect in any tender with respect to any
particular Common Share(s) or any particular shareholder, and the Fund's
interpretations of the terms and conditions of the Offer will be final and
binding. Unless waived, any defects or irregularities in connection with tenders
must be cured within such times as the Fund shall determine. Tendered Class A
Common Shares will not be accepted for payment unless the defects or
irregularities have been cured within such time or waived. Neither the Fund, the
Transfer Agent, the Administrator nor any other person shall be obligated to
give notice of any defects or irregularities in tenders, nor shall any of them
incur any liability for failure to give such notice.

         Federal Income Tax Withholding. To prevent backup federal income tax
withholding equal to 31% of the gross payments made pursuant to the Offer, each
shareholder who has not previously submitted a Form W-9 to the Fund or does not
otherwise establish an exemption from such withholding must notify the Transfer
Agent of such shareholder's correct taxpayer identification number (or certify
that such taxpayer is awaiting a taxpayer identification number) and provide
certain other information by completing the Form W-9 enclosed with the Letter of
Transmittal. Foreign shareholders who are individuals and who have not
previously submitted a Form W-9 to the Fund must do so in order to avoid backup
withholding.

         The Transfer Agent will withhold 30% of the gross payments payable to a
foreign shareholder unless the Transfer Agent determines that a reduced rate of
withholding or an exemption from withholding is applicable. (Exemption from
backup withholding does not exempt a foreign shareholder from the 30%
withholding). For this purpose, a foreign shareholder, in general is a
shareholder that is not (i) a citizen or resident of the United States, (ii) a
corporation, partnership or other entity created or organized in or under the
laws of the United States or any political subdivision thereof, or (iii) an
estate or trust the income of which is subject to United States federal income
taxation regardless of the source of such income. The Transfer Agent will
determine a shareholder's status as a foreign shareholder and eligibility for a
reduced rate of, or an exemption from, withholding by reference to the
shareholder's address and to any outstanding statements concerning eligibility
for a reduced rate of, or exemption from, withholding unless facts and
circumstances indicate that reliance is not warranted. A foreign shareholder who
has not previously submitted the appropriate statements with respect to a
reduced rate of, or exemption from, withholding for which such shareholder may
be eligible should consider doing so in order to avoid over-withholding. A
foreign shareholder may be eligible to obtain a refund of tax withheld if such
shareholder meets one of the three tests for capital gain or loss treatment
described in Section 15 or is otherwise able to establish that no tax or a
reduced amount of tax was due.

         For a discussion of certain other federal income tax consequences to
tendering shareholders, see Section 15.

         3.  EARLY WITHDRAWAL CHARGE.

         The Transfer Agent may impose an early withdrawal charge (the "Early
Withdrawal Charge" or "EWC") on certain Class A Common Shares accepted for
payment which have been held less than two years. An EWC of 1.0% or 0.5% may be
imposed on certain Class A Common Shares tendered and accepted for payment
within one or two years of purchase, respectively, for those Class A Common
Shares (i) purchased at NAV without a sales charge at time of purchase
(purchases of $1 million or more), (ii) acquired through an exchange for Class A
Shares of a Non-Money Fund of the Sierra Trust Funds purchased at NAV without a
sales charge at time of purchase (purchases of $1 million or more), (iii)
purchased through an employee benefit trust created pursuant to a plan qualified
under Section 401(k) of the Code ("401(k) Plan") that has invested in the
aggregate more than $1 million in the Fund, or (iv) purchased through a
retirement plan qualified under Section 403(b) of the Code ("403(b) Plan") that
has more than $1 million in the Fund. The EWCs for Class A Common Shares are
calculated on the lower of the shares' cost or current net asset value, and in
determining whether the EWC is payable, the Fund will first redeem shares not
subject to any EWC.

                                        6

<PAGE>   7
         Purchases of $1 million or more and certain other purchases are not
subject to the sales charge at the time of purchase, but may be subject to a
1.0% early withdrawal charge on repurchases or tenders within one year of
purchase or a 0.5% early withdrawal charge on repurchases or tenders during the
second year after purchase. No sales charge at time of purchase and no early
withdrawal charge will be assessed on the reinvestment of dividends or
distributions on Class A Common Shares or on purchases of Class A Common Shares
under the 180-day reinvestment privilege. The Early Withdrawal Charge may be
imposed on the number of Class A Common Shares (subject to the EWC as noted
above) accepted for payment from a record holder of Class A Common Shares the
value of which exceeds the aggregate value at the time the tendered Class A
Common Shares are accepted for payment of (a) all Class A Common Shares owned by
such holder that were purchased without being subject to the EWC, (b) the Class
A Common Shares owned by such holder that were acquired through reinvestment of
distributions, and (c) the increase, if any, of value of all other Class A
Common Shares owned by such holder over the purchase price of such Class A
Common Shares. The Early Withdrawal Charge will be paid to SISC on behalf of the
holder of the Class A Common Shares. In determining whether an Early Withdrawal
Charge is payable, Class A Common Shares accepted for payment pursuant to the
Offer shall be deemed to be those Class A Common Shares purchased earliest by
the Shareholder.

         The following example will illustrate the operation of the Early
Withdrawal Charge. Assume that an investor purchases $1,000,000 worth of the
Fund's Class A Common Shares for cash and that 9 months later the value of the
account has grown through the reinvestment of dividends and capital appreciation
to $1,050,000. The investor then may submit for repurchase pursuant to a tender
offer up to $50,000 worth of Class A Common Shares without incurring an Early
Withdrawal Charge. If the investor should submit for repurchase pursuant to a
tender offer $75,000 worth of Class A Common Shares, an Early Withdrawal Charge
would be imposed on $25,000 worth of the Class A Common Shares submitted. The
charge would be imposed at the rate of 1% because it is in the first year after
the purchase was made and the charge would be $250.

         4.  WITHDRAWAL RIGHTS.

         Except as otherwise provided in this Section 4, tenders of Class A
Common Shares made pursuant to the Offer will be irrevocable. You may withdraw
Class A Common Shares tendered at any time prior to the Expiration Date and, if
the Class A Common Shares have not yet been accepted for payment by the Fund, at
any time after 6:00 PM Pacific Standard Time on January 9, 1998.

         To be effective, a written, telegraphic, telex or facsimile
transmission notice of withdrawal must be timely received by the Administrator
at the address set forth on page 2 of this Offer to Purchase. Any notice of
withdrawal must specify the name of the person having tendered the Class A
Common Shares to be withdrawn and the number of Class A Common Shares to be
withdrawn.

         All questions as to the form and validity (including time of receipt)
of notices of withdrawal will be determined by the Fund in its sole discretion,
whose determination shall be final and binding. None of the Fund, Sierra
Shareholder Services, the Transfer Agent, the Administrator or any other person
is or will be obligated to give any notice of any defects or irregularities in
any notice of withdrawal, and none of them will incur any liability for failure
to give any such notice. Class A Common Shares properly withdrawn shall not
thereafter be deemed to be tendered for purposes of the Offer. However,
withdrawn Class A Common Shares may be retendered by following the procedures
described in Section 2 prior to the Expiration Date.

         5.  PAYMENT FOR SHARES.

         For purposes of the Offer, the Fund will be deemed to have accepted for
payment (and thereby purchased) Class A Common Shares which are tendered and not
withdrawn when, and if it gives oral or written notice to the Transfer Agent of
its acceptance of such Class A Common Shares for payment pursuant to the Offer.
Upon the terms and subject to the conditions of the Offer, the Fund will accept
for payment (and thereby purchase) Class A Common Shares properly tendered
promptly after the Expiration Date.

         Payment for Class A Common Shares purchased pursuant to the Offer will
be made by depositing the aggregate purchase price therefor with the Transfer
Agent, which will act as agent for tendering shareholders for the purpose of
receiving payment from the Fund and transmitting payment to the tendering
shareholders. In all cases, payment for Class A Common Shares accepted for
payment pursuant to the Offer will be made only after timely receipt by the
Administrator, as required pursuant to the Offer, of a properly, completed and
duly executed Letter of Transmittal (or manually signed facsimile thereof), and
any other required documents.

         The Fund will pay all transfer taxes, if any, payable on the transfer
to it of Class A Common Shares purchased pursuant to the Offer. If, however,
payment of the purchase price is to be made to, or (in the circumstances
permitted by the Offer) of unpurchased Class A Common Shares are to be
registered in the name of any person other than the registered holder the amount
of any transfer taxes (whether imposed on the registered holder or such other
person) payable on account of the transfer to such person will be deducted from
the Purchase Price unless satisfactory evidence of the payment of such taxes, or
exemption therefrom, is submitted. Shareholders tendering Class A Common Shares
shall be entitled to receive all dividends declared on or prior to settlement
following the Expiration Date, but not yet paid, on Class A Common Shares
tendered pursuant to the Offer. The Fund will not pay any interest on the
Purchase Price under any circumstances. An Early Withdrawal Charge may be
imposed on certain Class A Common Shares accepted for payment that have been
held for less than two years. See Section 3. In addition, if certain events
occur, the Fund may not be obligated to purchase Class A Common Shares pursuant
to the Offer. See Section 6.

         ANY TENDERING SHAREHOLDER OR OTHER PAYEE WHO HAS NOT PREVIOUSLY
SUBMITTED A COMPLETED AND SIGNED SUBSTITUTE FORM W-9 AND WHO FAILS TO COMPLETE
FULLY AND SIGN THE SUBSTITUTE FORM W-9 ENCLOSED WITH THE LETTER OF TRANSMITTAL
MAY BE SUBJECT TO REQUIRED FEDERAL INCOME TAX WITHHOLDING OF 31% OF THE GROSS
PROCEEDS PAID TO SUCH SHAREHOLDER OR OTHER PAYEE PURSUANT TO THE OFFER. SEE
SECTION 2.

         6.  CERTAIN CONDITIONS OF THE OFFER.

         Notwithstanding any other provision of the Offer, the Fund shall not be
required to accept for payment, purchase or pay for any Class A Common Shares
tendered, and may terminate or amend the Offer or may postpone the acceptance
for payment of, the purchase of and payment for Class A Common Shares tendered,
if at any time at or before the time of purchase of any such Class A Common
Shares, any of the following events shall have occurred (or shall have been
determined by the Fund to have occurred) which, in the Fund's reasonable
judgment in any such case and regardless of the circumstances (including any
action or omission to act by the Fund), makes it inadvisable to proceed with the
Offer or with such purchase or payment: (1) in the reasonable and exclusive
judgment of the Trustees, there is not sufficient liquidity of the assets of the
Fund; (2) such transactions, if consummated, would (a) impair the Fund's status
as a regulated investment company under the Internal Revenue Code (which would
make the Fund a taxable entity, causing the Fund's taxable income to be taxed at
the Fund level) or (b) result in a failure to comply with applicable asset
coverage requirements; or (3) there is, in the Board of Trustees' judgment, any
(a) material legal action or proceeding instituted or threatened challenging
such transactions or otherwise materially adversely affecting the Fund, (b)
suspension of or limitation on prices for trading securities generally on any
United States national securities exchange or in the over-the-counter market,
(c) declaration of a banking moratorium by federal or state authorities or any
suspension of payment by banks in the United States, (d) limitation affecting
the Fund or the issuers of its portfolio securities imposed by federal or state
authorities on the extension of credit by lending institutions, (e) commencement
of war, armed hostilities or other international or national calamity directly
or indirectly involving the United States or (f) other event or condition which
would have a material adverse effect on the Fund or the holders of its Class A
Common Shares if the tendered Class A Common Shares are purchased.

         The foregoing conditions are for the Fund's sole benefit and may be
asserted by the Fund regardless of the circumstances giving rise to any such
condition (including any action or inaction by the Fund), and any such condition
may be waived by the Fund in whole or in part, at any time and from time to time
in its sole discretion. The Fund's failure at any time to exercise any of the
foregoing, rights shall not be deemed a waiver of any such right; the waiver of
any such right with respect to particular facts and circumstances shall not be
deemed a waiver with respect to any other facts or circumstances; and each such
right shall be deemed an ongoing right which may be asserted at any time and
from time to time. Any determination by the Fund concerning the events described
in this Section 6 shall be final and shall be binding on all parties.


                                        8

<PAGE>   9
         If the Fund determines to terminate or amend the Offer or to postpone
the acceptance for payment of or payment for Class A Common Shares tendered, it
will, to the extent necessary, extend the period of time during which the Offer
is open as provided in Section 16. Moreover, in the event any of the foregoing
conditions arc modified or waived in whole or in part at any time, the Fund will
promptly make a public announcement of such waiver and may, depending on the
materiality of the modification or waiver, extend the Offer period as provided
in Section 16.

         7.  PURPOSE OF THE OFFER.

         The Fund currently does not believe that an active secondary market for
its Class A Common Shares exists or is likely to develop. In recognition of the
possibility that a secondary market may not develop for the Class A Common
Shares of the Fund, or, if such a market were to develop, the Class A Common
Shares might trade at a discount, the Trustees have determined that it would be
in the best interest of its shareholders for the Fund to take action to attempt
to provide liquidity to shareholders or to reduce or eliminate any future market
value discount from NAV that might otherwise exist, respectively. To that end,
the Trustees presently intend each quarter to consider making a tender offer to
purchase Class A Common Shares at their NAV. The purpose of this Offer is to
attempt to provide liquidity to the holders of Class A Common Shares. There can
be no assurance that this Offer will provide sufficient liquidity to all holders
of Class A Common Shares that desire to sell their Class A Common Shares or that
the Fund will make any such tender offer in the future.

         NEITHER THE FUND NOR ITS BOARD OF TRUSTEES MAKES ANY RECOMMENDATION TO
ANY SHAREHOLDER AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ANY OR ALL OF
SUCH SHAREHOLDER'S CLASS A COMMON SHARES AND HAS NOT AUTHORIZED ANY PERSON TO
MAKE ANY SUCH RECOMMENDATION. SHAREHOLDERS ARE URGED TO EVALUATE CAREFULLY ALL
INFORMATION IN THE OFFER, CONSULT THEIR OWN INVESTMENT AND TAX ADVISORS AND MAKE
THEIR OWN DECISIONS WHETHER TO TENDER CLASS A COMMON SHARES AND, IF SO, HOW MANY
CLASS A COMMON SHARES TO TENDER.

         8.  PLANS OR PROPOSALS OF THE FUND.

         The Fund has no present plan or proposals which relate to or would
result in any extraordinary transaction such as a merger, reorganization or
liquidation involving the Fund; a sale or transfer of a material amount of
assets of the Fund other than in its ordinary course of business; any material
changes in the Fund's present capitalization (except as resulting from the Offer
or otherwise set forth herein); or any other material changes in the Fund's
structure or business.

         9. PRICE RANGE OF CLASS A COMMON SHARES; DIVIDENDS.

         The Fund's NAV per Class A Common Share from February 14, 1996
(inception of the Fund) through December 10, 1997 ranged from a high of $10.01
to a low of $10.00. On December 1, 1997, the NAV was $10.00 per Common Share.
You can obtain current NAV quotations from Sierra Shareholder Services by
calling (800) 222-5852 between the hours of 6:00 AM and 6:00 PM Pacific Standard
Time, Monday through Friday and 6:00 AM to 3:00 PM Pacific Standard Time on
Saturday, except holidays. Holders of Class A Common Shares may tender or
withdraw previously tendered shares to the Administrator at the address set
forth on page 2 of this Offer to Purchase by written, telegraphed, telex or
facsimile transmission of a notice of withdrawal prior to the Expiration Date.
The Fund offers and sells its Class A Common Shares to the public on a
continuous basis through SISC as principal underwriter. The Fund is not aware of
any secondary market trading for the Class A Common Shares. Dividends on the
Class A Common Shares are declared daily and paid monthly.

         Since the commencement of the Trust's operations in February 1996 prior
to the Offer, the Fund paid the following dividends per Class A Common Share
held for the entire respective dividend period:

Shareholders tendering Class A Common Shares shall be entitled to receive all
dividends declared on or prior to settlement following the Expiration Date, but
not yet paid, on Class A Common Shares tendered pursuant to the Offer.

         10.    INTEREST OF TRUSTEES AND EXECUTIVE OFFICERS; TRANSACTIONS AND
                ARRANGEMENTS CONCERNING THE CLASS A COMMON SHARES.

         Except as set forth in this Section 10, as of December 1, 1997, the
trustees and executive officers of the Fund as a group beneficially owned no
Class A Common Shares. The Fund has been informed that no trustee or executive
officer of the Fund intends to tender any Class A Common Shares pursuant to the
Offer.

         Except as set forth in this Section 10, based upon the Fund's records
and upon information provided to the Fund by its trustees, executive officers
and affiliates (as such term is used in the Securities Exchange Act of 1934),
neither the Fund nor, to the best of the Fund's knowledge, any of the trustees
or executive officers of the Fund, nor any associates of any of the foregoing,
has effected any transactions in the Class A Common Shares during the forty
business day period prior to the date hereof.

         Except as set forth in this Offer to Purchase, neither the Fund nor, to
the best of the Fund's knowledge, any of its affiliates, trustees or executive
officers, is a party to any contract, arrangement, understanding or relationship
with any other person relating, directly or indirectly, to the Offer with
respect to any securities of the Fund (including, but not limited to, any
contract, arrangement, understanding or relationship concerning the transfer or
the voting of any such securities, joint ventures, loan or option arrangements,
puts or calls, guaranties of loans, guaranties against loss or the giving or
withholding of proxies, consents or authorizations).

         The Fund currently is a party to an Investment Advisory Agreement with
Sierra Investment Advisors Corporation ("Sierra Advisors" or "Adviser") under
which the Fund accrues daily and pays monthly to Sierra Advisors an investment
management fee equal to 0.95% of the average daily net assets (i.e. the daily
value of the total assets of the Fund, minus the sum of the accrued liabilities
of the Fund other than the aggregate amount of any borrowings undertaken by the
Fund). Sierra Advisors has delegated the management of the Fund's portfolio to
Van Kampen American Capital Management Inc. ("Van Kampen" or "Sub-Advisor")
pursuant to an Investment Sub-Advisory Agreement among the Fund, Sierra Advisors
and Van Kampen. The Fund also is a party to an Administration Agreement with
Sierra Fund Administration Corporation ("Sierra Administration") and a
Distribution Agreement with Sierra Investment Services Corporation ("SISC").
Under the current Administration Agreement, which was amended effective July 1,
1996, the Fund pays Sierra Administration a monthly fee at the annualized rate
of 0.25% of the Fund's average daily net assets. Prior to July 1, 1996, the Fund
paid Sierra Administration a monthly fee at the annualized rate of 0.35% of the
Fund's average daily net assets. Under the Distribution Agreement, the Fund
offers and sells its Class A Common Shares to the public on a continuous basis
through SISC, as principal underwriter. Sierra Administration pursuant to a
Sub-Administration Agreement with State Street Bank & Trust Company ("State
Street") has delegated certain administrative and custodial services to State
Street. The Fund is also a party to a Transfer Agency and Services Agreement
with First Data Investor Services Group, Inc. ("First Data") in connection with
certain transfer agency responsibilities.

         On July 1, 1997, Great Western Financial Corporation ("GWFC"), the
indirect parent of Sierra Advisors, and Washington Mutual, Inc. ("Washington
Mutual"), a publicly-held financial services company, consummated a previously
announced Agreement and Plan of Merger resulting in the merger of GWFC with an
into a wholly owned subsidiary of Washington Mutual (the "Merger"). As a result
of the Merger, Sierra Advisors and its affiliates are now indirect subsidiaries
of Washington Mutual. A Special Meeting of Shareholders to be held on December
23, 1997 (the "Special Meeting") is being called in preparation for the planned
consolidation of the funds managed by Sierra Advisors and its affiliates and
those managed by Composite Research & Management Co. ("Composite"), an
investment adviser which also is an indirect subsidiary of Washington Mutual.
The planned consolidation is expected to result in a common Board of Trustees
and a single investment adviser. The primary purpose of the Special Meeting is
to (1) ask shareholders to elect a Board of Trustees, (2) permit shareholders to
consider a new Investment Management Agreement between the Trust and Composite,
and (3) permit shareholders to consider a new Investment Sub-Advisory Agreement
between Composite and Van Kampen to take effect at the time of the effectiveness
of the New Management Agreement. The Trust's New Management Agreement and New
Sub-Advisory Agreement will be substantially similar to the Trust's current
investment advisory agreement and current investment sub-advisory agreement,
except for the parties and dates of execution, effectiveness and initial term.

         11.  CERTAIN EFFECTS OF THE OFFER.

         The purchase of Class A Common Shares pursuant to the Offer will have
the effect of increasing the proportionate interest in the Fund of shareholders
who do not tender their Class A Common Shares. If you retain your Class A Common
Shares you will be subject to any increased risks that may result from the
reduction in the Fund's aggregate assets resulting from payment for the tendered
Class A Common Shares (e.g., greater volatility due to decreased diversification
and higher expenses). However, the Fund believes that since it is engaged in a
continuous offering of the Class A Common Shares, those risks would be reduced
to the extent new Class A Common Shares of the Fund are sold. All Class A Common
Shares purchased by the Fund pursuant to the Offer will be held in treasury
pending disposition.

<PAGE>   12
         12.  SOURCE AND AMOUNT OF FUNDS.

         The total cost to the Fund of purchasing the full 161,925 Class A
Common Shares pursuant to the Offer would be approximately $1,619,250 (assuming
a NAV of $10.00 per Common Share on the Expiration Date). The Fund anticipates
that the Purchase Price for any Class A Common Shares acquired pursuant to the
Offer will first be derived from cash on hand, such as proceeds from sales of
new Class A Common Shares of the Fund and specified pay-downs from the
participation interests in senior corporate loans which it has acquired, and
then from the proceeds from the sale of cash equivalents held by the Fund.
Although the Fund is authorized to borrow money to finance the repurchase of
Class A Common Shares, the Fund believes that it has sufficient liquidity to
purchase the Class A Common Shares tendered pursuant to the Offer without
utilizing such borrowing. However, if, in the judgment of the Trustees, there is
not sufficient liquidity of the assets of the Fund to pay for tendered Class A
Common Shares, the Fund may terminate the Offer. See Section 6.

         The Fund has entered into a Credit Agreement dated May 22, 1996, with
Deutsche Bank AG, New York Branch ("Deutsche Bank"), first extended to October
28, 1997 by a first amendment dated as of July 30, 1997 and by a second
amendment dated as of October 27, 1997 extending the agreement to December 31,
1997, pursuant to which Deutsche Bank has agreed to provide a credit facility in
the maximum amount of $40,000,000 in the aggregate to the Fund and the Sierra
Trust Funds, which is not secured by the assets of the Fund or other collateral.
The Fund and/or the Sierra Trust Funds have not drawn down any of the money
available under the Deutsche Bank Agreement. The purpose of the Deutsche Bank
Agreement is to provide the Fund with additional liquidity to meet its
obligations to purchase Common Shares pursuant to any tender offer that it may
make. The Deutsche Bank Agreement has terms and conditions substantially similar
to the following:

                  a.       The Fund is entitled to borrow from Deutsche Bank
                           amounts which in the aggregate do not exceed
                           $433,000. The Fund together with the portfolios of
                           the Sierra Trust Funds will be limited to a maximum
                           credit extension of $40,000,000. The Fund will be
                           entitled to obtain a Base Rate or NIBOR loan on the
                           business day Deutsche Bank receives a Notice of
                           Borrowing if provided by 12:00 pm (Eastern standard
                           time). For LIBOR Loans, the Fund will be entitled to
                           a loan on the third business day following the Notice
                           of Borrowing is provided to Deutsche Bank.

                  b.       The aggregate principal amount of each borrowing
                           under the Deutsche Bank Agreement must be at least
                           $50,000, with additional amounts in $10,000
                           increments.

                  c.       Base Rate Loans made under the Deutsche Bank
                           Agreement, if any, will bear interest daily at a rate
                           equal to the higher of (i) one-half of one percent
                           (1/2 of 1%) in excess of the Federal Funds Rate and
                           (ii) the Prime Lending Rate. Such interest will be
                           due on the outstanding principal amount of each loan
                           on the last business day of March, June, September
                           and December. Overdue payments of principal and
                           interest will bear interest, payable upon demand, at
                           a penalty rate.

                  d.       NIBOR Loans made under the Deutsche Bank Agreement,
                           if any, will bear interest daily at a rate equal to
                           the sum of the NIBOR Rate plus 35% of 1%. The NIBOR
                           Rate is the offered quotation in the New York
                           Interbank market to Deutsche Bank for loans of
                           comparable interest and maturity. Such interest will
                           be due on the outstanding principal amount of each
                           loan on each Interest Payment Date, which at the
                           option of the Fund may be either 30 days or
                           quarterly. Overdue payments of principal and interest
                           will bear interest, payable on demand, at a penalty
                           rate.

                  e.       LIBOR Loans made under the Deutsche Bank Agreement,
                           if any, will bear interest daily at a rate equal to
                           the sum of the LIBOR Rate plus 35% of 1%. The LIBOR
                           Rate is the offered quotation in the London Interbank
                           market to Deutsche Bank for loans of comparable
                           principal and maturity. Such interest will be due on
                           the outstanding principal amount of each loan on each
                           Interest Payment Date, which at the option of the
                           Fund, may be a one, two, three or six-month

                                       12

<PAGE>   13



                           period. Overdue payments of principal and interest
                           will bear interest, payable on demand, at a penalty
                           rate.

                  f.       During the term of the Deutsche Bank Agreement, the
                           Fund is obligated to pay a commitment fee computed at
                           a rate equal to 1/20 of 1% per annum on the average
                           daily amount of the unutilized commitment.

                  g.       The principal amount of loans made under the Deutsche
                           Bank Agreement, if any, are required to be paid on
                           the last day of the applicable Interest Period. Any
                           loans outstanding must be repaid in full not later
                           than the Expiration Date of the Agreement. On the
                           Expiration Date, all outstanding principal and
                           accrued interest under the Deutsche Bank will be due
                           and payable in full.

                  h.       The Deutsche Bank Agreement contains various
                           affirmative and negative covenants of the Fund,
                           including, without limitation, obligations: (i) to

                           maintain its existence as a business trust; (iv) to

                           Advisors; and (ix) a change of control in the
                           Investment Advisors.

                  j.       The Fund expects that the Deutsche Bank Agreement
                           will be extended in the near future pursuant to the
                           terms thereof.

         The Fund intends to repay any loans under the Deutsche Bank Agreement
from the specified pay-downs from interests in Senior Loans which will be
acquired and from the sale of Common Shares.

         The foregoing descriptions of the Deutsche Bank Agreement do not
purport to be complete or final and are qualified in their entirety by reference
to the Deutsche Bank Agreement included as Exhibit (B) to the Issuer Tender
Offer Statement on Schedule 13E-4 of the Fund. See Section 14.

         13.  CERTAIN INFORMATION ABOUT THE FUND.

         The Fund was organized as a Massachusetts business trust on October 4,
1995 and is a non-diversified, closed-end management investment company under
the Investment Company Act of 1940. The Fund seeks as high a level of current
income as is consistent with the preservation of capital by investing in a
professionally managed portfolio of interests in floating or variable rate
senior loans ("Senior Loans") to United States corporations, partnerships and
other entities ("Borrowers"). Although the Fund's NAV will vary, the Fund's
policy of acquiring interests in floating or variable rate Senior Loans is
expected to minimize fluctuations in the Fund's NAV as a result of changes in
interest rates. Senior Loans in which the Fund will invest generally pay
interest at rates which are periodically redetermined by reference to a base
lending rate plus a premium. These base lending rates are generally the prime
rate offered by one or more major United States banks ("Prime Rate"), the London
Inter-Bank Offered Rate ("LIBOR"), the certificate of deposit rate or other base
lending rates used by commercial lenders. The Fund seeks to achieve over time a
high effective yield. The Senior Loans in the Fund's portfolio at all times have
a dollar-weighted average time until next interest rate redetermination of 90
days or less. As a result, as short-term interest rates increase, the interest
payable to the Fund from its investments in Senior Loans should increase, and as
short-term interest rates decrease, the interest payable to the Fund on its
investments in Senior Loans should decrease. The amount of time required to pass
before the Fund realizes the effects of changing short-term market interest
rates on its portfolio varies with the dollar-weighted average time until next
interest rate redetermination on securities in the Fund's portfolio.

         The Fund has registered as a "non-diversified" investment company so
that, subject to its investment restrictions, it is able to invest more than 5%
of the value of its assets in the obligations of any single issuer, including
Senior Loans of a single Borrower or participations in Senior Loans purchased
from a single lender. To the extent the Fund invests a relatively high
percentage of its assets in obligations of a limited number of issuers, the Fund
will be more susceptible than a more widely diversified investment company to
any single corporate, economic, political or regulatory occurrence.

         SISC compensates Authorized Dealers participating in the continuous
offering of the Fund's Class A Common Shares pursuant to the following schedule:

</TABLE>


         SISC may pay Authorized Dealers a fee of up to 1.00% of net asset value
for Class A Common Share transactions over $1,000,000. The dealer reallowance
may be changed by SISC from time to time, and upon notice, SISC may reallow up
to the full applicable sales charge to certain Authorized Dealers. In addition,
if Class A Common Shares of the Fund are sold by an Authorized Dealer, Sierra
Advisors may in its discretion pay up to a maximum of 0.25% of the value of such
Common Shares to such Authorized Dealers. Such compensation is or will be paid
by Sierra Advisors out of its own assets, and not out of the assets of the Fund.
The compensation paid to such Authorized Dealers and to SISC, including the
compensation paid at the time of purchase, the quarterly payments, any
additional incentives paid from time to time and the EWC, if any, will not in
the aggregate exceed the applicable limit (currently 8.5%) imposed by the
National Association of Securities Dealers (the "NASD"), unless the approval of
the NASD has been received.

         The principal executive offices of the Fund are located at 9301 Corbin
Avenue, Suite 333, Northridge, CA 91324.

         Reference is hereby made to Section 9 of this Offer to Purchase and the
financial statements attached hereto as Exhibit A which are incorporated herein
by reference.

         14.  ADDITIONAL INFORMATION.

         The Fund has filed an Issuer Tender Offer Statement on Schedule 13E-4
with the Securities and Exchange Commission (the "Commission") which includes
certain additional information relating to the Offer. Such material may be
inspected and copied at prescribed rates at the Commission's public reference
facilities at Judiciary Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549
and 5670 Wilshire Boulevard, 11th Floor, Los Angeles, CA 90036-3648. Copies of
such material may also be obtained by mail at prescribed rates from the Public
Reference Branch of the Commission at 450 Fifth Street, N.W., Washington, D.C.
20549.

         15.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES.

         The following discussion is a general summary of the federal income tax
consequences of a sale of Class A Common Shares pursuant to the Offer.
Shareholders should consult their own tax advisers regarding the tax
consequences of a sale of Class A Common Shares pursuant to the Offer, as well
as the effects of state, local and foreign tax laws.

         The sale of Class A Common Shares pursuant to the Offer will be a
taxable transaction for federal income tax purposes, either as a "sale or
exchange," or, under certain circumstances, as a "dividend." Under Section
302(b) of the Internal Revenue Code of 1986, as amended (the "Code"), a sale of
Class A Common Shares pursuant to the Offer generally will be treated as a "sale
or exchange" if the receipt of cash: (a) results in a "complete termination" of
the shareholder's interest in the Fund, (b) is "substantially disproportionate"
with respect to the shareholder, or (c) is "not essentially equivalent to a
dividend" with respect to the shareholder. In determining whether any of these
tests has been met, Class A Common Shares actually owned, as well as Class A
Common Shares considered to be owned by the shareholder by reason of certain
constructive ownership rules set forth in Section 318 of the Code, generally
must be taken into account. If any of these three tests for "sale or exchange"
treatment is met, a shareholder will recognize gain or loss equal to the
difference between the amount of cash received pursuant to the Offer and the tax
basis of the Class A Common Shares sold. If such Class A Common Shares are held
as a capital asset, the gain or loss will be a capital gain or loss and will be
long-term if such Class A Common Shares have been held for more than one year.

         If none of the tests set forth in Section 302(b) of the Code is met,
amounts received by a shareholder who sells Class A Common Shares pursuant to
the Offer will be taxable to the shareholder as a "dividend" to the extent of
such shareholder's allocable share of the Fund's current or accumulated earnings
and profits, and the excess of such amounts received over the portion that is
taxable as a dividend would constitute a non-taxable return of capital (to the
extent of the shareholder's tax basis in the Class A Common Shares sold pursuant
to the Offer) and any amounts in excess of the shareholder's tax basis would
constitute taxable gain. Thus, a shareholder's tax basis in the Class A Common
Shares sold will not reduce the amount of the "dividend." Any remaining tax
basis in the Class A Common Shares tendered to the Fund will be transferred to
any remaining Class A Common Shares held by such shareholder. In addition, if a
tender of Class A Common Shares is treated as a "dividend" to a tendering
shareholder, a constructive dividend under Section 305 (c) of the Code may
result to a non- tendering shareholder whose proportionate interest in the
earnings and assets of the Fund has been increased by such tender.

         16.  EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENTS.

         The Fund reserves the right, at any time and from time to time, to
extend the period of time during which the Offer is pending by making a public
announcement thereof. In the event that the Fund so elects to extend the tender
period, the Purchase Price for the Class A Common Shares tendered will be
determined as of 2:00 PM Pacific Standard Time on the Expiration Date, as
extended, and the Offer will terminate as of 6:00 PM Pacific Standard Time on
the Expiration Date, as extended. During any such extension, all Class A Common
Shares previously tendered and not purchased or withdrawn will remain subject to
the Offer. Holders of Class A Common Stock may tender or withdraw previously
tendered shares to the Administrator at the address set forth on page 2 of this
Offer to Purchase by written, telegraphed, telex or facsimile transmission of a
notice of withdrawal prior to the Expiration Date. The Fund also reserves the
right, at any time and from time to time up to and including the Expiration
Date, to (a) terminate the Offer and not to purchase or pay for any Class A
Common Shares or, subject to applicable law, postpone payment for Class A Common
Shares upon the occurrence of any of the conditions specified in Section 6, and
(b) amend the Offer in any respect by making a public announcement thereof. Such
public announcement will be issued no later than 9:00 AM Pacific Standard Time
on the next business day after the previously scheduled Expiration Date and will
disclose the approximate number of Class A Common Shares tendered as of that
date. Without limiting the manner in which the Fund may choose to make a public
announcement of extension, termination or amendment, except as provided by
applicable law (including Rule 13e-4(e) (2)), the Fund shall have no obligation
to publish, advertise or otherwise communicate any such public announcement,
other than by making a release to the Dow Jones News Service.

         If the Fund materially changes the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, the Fund will extend the Offer to the extent required by Rule 13e-4
promulgated under the Exchange Act. These rules require that the minimum period
during which an offer must remain open following material changes in the terms
of the offer or information concerning the offer (other than a change in price
or a change in percentage of securities sought) will depend on the facts and
circumstances, including the relative materiality of such terms or information.
If (i) the Fund increases or decreases the price to be paid for Class A Common
Shares, or the Fund increases the number of Class A Common Shares being sought
by an amount exceeding 2% of the outstanding Class A Common Shares, or the Fund
decreases the number of Class A Common Shares being sought and (ii) the Offer is
scheduled to expire at any time earlier than the expiration of a period ending
on the tenth business day from, and including, the date that notice of such
increase or decrease is first published, sent or given, the Offer will be
extended at least until the expiration of such period of ten business days.

         17.  MISCELLANEOUS.

         The Offer is not being made to, nor will the Fund accept tenders from,
owners of Class A Common Shares in any jurisdiction in which the Offer or its
acceptance would not comply with the securities or Blue Sky laws of such
jurisdiction. The Fund is not aware of any jurisdiction in which the making of
the Offer or the tender of Class A Common Shares would not be in compliances
with the laws of such jurisdiction. However, the Fund reserves the right to
exclude holders in any jurisdiction in which it is asserted that the Offer
cannot lawfully be made. So long as the Fund makes a good-faith effort to comply
with any state law deemed applicable to the Offer, the Fund believes that the
exclusion of holders residing in such jurisdiction is permitted under Rule
13e-4(f)(9) promulgated under the Exchange Act. In any jurisdiction the
securities or Blue Sky laws of which require the Offer to be made by a licensed
broker or dealer, the Offer shall be deemed to be made on the Fund's behalf by
one or more registered brokers or dealers licensed under the laws of such
jurisdiction.

                            SIERRA PRIME INCOME FUND
                      PORTFOLIO OF INVESTMENTS (CONTINUED)
                               SEPTEMBER 30, 1997



* Senior loans in which the Sierra Prime Income Fund invests generally pay
interest at rates which are periodically redetermined by reference to a base
lending rate plus a premium. These base lending rates are generally (i) the
prime rate offered by one or more major United States banks; (ii) the lending
rate offered by one or more major European banks, such as the London Inter-Bank
Offered Rate (LIBOR); or (iii) the certificate of deposit ratio. Senior loans
are generally considered to be restricted in that the Fund ordinarily is
contractually obligated to receive approval from the Agent Bank and/or borrower
prior to the disposition of a senior loan. Within each loan there may be
different rates due to different reset dates. The rates disclosed for each loan
are the weighted average coupon rates as of September 30, 1997.

** Senior loans in the Sierra Prime Income Fund's portfolio generally are
subject to mandatory and/or optional prepayment. Because of these mandatory
prepayment conditions and because there may be significant economic incentives
for a Borrower to prepay, prepayments of senior loans in the Fund's portfolio
may occur. As a result, the actual remaining maturity of senior loans held in
the Fund's portfolio may be substantially less than the stated maturities shown.
Although the Fund is unable to accurately estimate the actual remaining maturity
of individual senior loans, the Fund estimates that the actual average maturity
of the senior loans held in its portfolio will be approximately 18-24 months.

+ At September 30, 1997, the aggregate cost for federal tax purposes was
$8,324,315. The gross unrealized appreciation for all securities in which there
is an excess of value over tax cost and aggregate gross unrealized depreciation
for all securities in which there is an excess of tax cost over value were
$1,530 and $79, respectively.

                            SIERRA PRIME INCOME FUND
                          NOTES TO FINANCIAL STATEMENTS


1.  ORGANIZATION AND BUSINESS

Sierra Prime Income Fund (the "Fund") is registered under the Investment Company
Act of 1940, as amended ("1940 Act"), as a non-diversified, closed-end
management investment company. The Fund was organized as a Massachusetts
business trust on October 4, 1995. During the period October 4, 1995 to February
15, 1996, the Fund had no operations other than those related to organizational
matters, including the initial capital contribution of $100,000 and the issuance
of 10,000 shares of beneficial interest to Sierra Fund Administration
Corporation.

The Trustees of the Fund authorized an unlimited number of Common Shares with
separate classes of beneficial interest. Currently there are only Class A Common
Shares. Shares are continuously offered at a price equal to the next determined
net asset value ("NAV") per share plus a maximum sales charge based on a
determined schedule.

2.  SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Sierra Prime Income
Fund in the preparation of its financial statements.

Portfolio Valuation:

Senior Loans are not actively traded in a public market. Sierra Investment
Advisors Corporation (the "Advisor"), and Van Kampen American Capital Management
Inc. (the "Sub-Advisor"), following procedures established by the Fund's Board
of Trustees, value the Senior Loan interests held by the Fund at fair value. In
valuing a Senior Loan interest, the Advisor and Sub-Advisor consider relevant
factors, data and information, including: (i) the characteristics of and
fundamental analytical data relating to the Senior Loan, including the cost,
size, current interest rate, period until next interest rate reset, maturity and
base lending rate of the Senior Loan interest, the terms and conditions of the
Senior Loan and any related agreements, and the position of the Senior Loan in
the Borrower's debt structure; (ii) the nature, adequacy and value of the
collateral, including the Fund's rights, remedies and interests with respect to
the collateral; (iii) the creditworthiness of the Borrower's business, cash
flows, capital structure and future prospects; (iv) information relating to the
market for Senior Loans, including price quotations for (if considered reliable)
and trading in Senior Loans and interests in similar Loans; (v) the reputation
and financial condition of the Agent and any Intermediate Participants in the
Senior Loans; and (vi) general economic and market conditions affecting the fair
value of Senior Loans.

Other Fund holdings (other than short term obligations, but including listed
issues) are valued on the basis of prices furnished by one or more pricing
services which determine prices for normal, institutional-size trading units of
such securities using market information, transactions for comparable securities
and various relationships between securities which are generally recognized by
institutional traders. In certain circumstances, portfolio securities will be
valued at the last sale price on the exchange that is the primary market for
such securities, or the average of the last quoted bid price and asked price for
those securities for which the over-the-counter market is the primary market or
for listed securities in which there were no sales during the day.

                            SIERRA PRIME INCOME FUND
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


Short-term obligations which mature in 60 days or less are valued at amortized
cost, if their original term to maturity when acquired by the Fund was 60 days
or less, or are valued at amortized cost using their value on the 61st day prior
to maturity, if their original term to maturity when acquired by the Fund was
more than 60 days, unless in each case this is determined not to represent fair
value. Repurchase agreements will be valued by the Fund at cost plus accrued
interest. Securities for which there exist no price quotations or valuations and
all other assets are valued at fair value as determined in good faith by or on
behalf of the Board of Trustees.

Illiquid Investments:

Senior Loans in which the Fund invests presently are not readily marketable and
may be subject to restrictions on resale. Interests in Senior Loans generally
are not listed on any national securities exchange or automated quotation system
and no regular market has developed for such interests. Although interests in
Senior Loans are traded among certain financial institutions in private
transactions between buyers and sellers these loans continue to be considered
illiquid. Senior Loans' illiquidity may impair the Fund's ability to realize the
full value of its assets in the event of a voluntary or involuntary liquidation
of such assets. Liquidity relates to the ability of the Fund to sell an
investment in a timely manner. The market for relatively illiquid securities
tends to be more volatile than the market for more liquid securities. The Fund
has no limitation on the amount of its assets which may be invested in
securities which are not readily marketable or are subject to restriction on
resale. The substantial portion of the Fund's assets invested in relatively
illiquid Senior Loan interests may restrict the ability of the Fund to dispose
of its investments in Senior Loans in a timely fashion and at a fair price, and
could result in capital losses to the Fund and holders of Common Shares.
However, many of the Senior Loans in which the Fund invests are of a relatively
large principal amount and are held by a relatively large number of owners which
should, in the Advisor's opinion, enhance the relative liquidity of such
interests. The risks associated with illiquidity are particularly acute in
situations where the Fund's operations require cash, such as when the Fund
tenders (Note 5) for its Common Shares and may result in the Fund borrowing to
meet short-term cash requirements.

Cash Flow Information:

The cash amount in the Statement of Cash Flows is the amount reported in the
Statement of Assets and Liabilities and does not include any short-term
investments at September 30, 1997. The Fund issues its shares, invests in
securities, and makes distributions from net investment income and net capital
gains (which are either paid in cash or reinvested at the discretion of
shareholders). These activities are reported in the Statement of Changes in Net
Assets. Information on cash receipts and payments is presented in the Statement
of Cash Flows.

Repurchase Agreements:

The Fund may enter into repurchase agreements (a purchase of, and a simultaneous
commitment to resell, a financial instrument at an agreed upon price on an
agreed upon date) only with member banks of the Federal Reserve System and
member firms of the New York Stock Exchange. When participating in repurchase
agreements, the Fund buys securities from a vendor (e.g., a bank or brokerage
firm) with the agreement that the vendor will repurchase the securities at a
higher price at a later date. Such transactions afford an opportunity for the
Fund to earn a return on available cash at minimal market risk, although the
Fund may be subject to various delays and risks of loss if the vendor is unable
to meet its obligation to repurchase. Under the 1940 Act, repurchase agreements
are deemed to be collateralized loans of money by the Fund to the seller. In
evaluating whether to enter into a repurchase agreement, the Advisor will
consider carefully the creditworthiness of the vendor. If the member bank or
member firm that is the party to the repurchase agreement petitions for
bankruptcy or otherwise becomes subject to the U.S. Bankruptcy Code, the law
regarding the rights of the Fund is unsettled. The securities underlying a


                                      -9-

<PAGE>   26
                            SIERRA PRIME INCOME FUND
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


repurchase agreement will be marked to market every business day so that the
value of the collateral is at least equal to the value of the loan, including
the accrued interest thereon, and the Advisor will monitor the value or the
collateral. No specific limitations exists as to the percentage of the Fund's
assets which may be used to participate in repurchase agreements.

Securities Transactions and Investment Income:

Securities transactions are recorded on trade date (the date the order to buy or
sell is executed). Realized gains and losses from securities sold are recorded
on the identified cost basis. Income is recorded on the accrual basis and
consists of interest accrued and discount earned less premiums amortized.
Facility fees are received upon the purchase of a new loan and are recognized as
income ratably over the expected life of the loan. The deferred facility fees
are the "unearned" portion of these facility fees. The Fund may purchase and
sell interest in Senior Loans and other portfolio securities on a "when issued"
and "delayed delivery" basis. No income accrues to the Fund on such interests or
securities in connection with such purchase transactions prior to the date the
Fund actually takes delivery of such interest or securities. When the Fund is
the buyer in such a transaction, however, it will maintain, in a segregated
account with its custodian, cash or high-grade portfolio securities having an
aggregate value equal to the amount of such purchase commitments until payment
is made.

Dividends and Distributions to Shareholders:

The Fund's policy is to declare daily and pay monthly distributions to holders
of Class A Common Shares of substantially all net investment income of the Fund.
Distributions of any net long-term capital gains earned by the Fund are made
annually. Distributions of any net short-term capital gains earned by the Fund
are distributed no less frequently than annually at the discretion of the Board
of Trustees. Additional distributions of net investment income and capital gains
for the Fund may be made at the discretion of the Board of Trustees in order to
avoid the application of a 4% non-deductible excise tax on certain undistributed
amounts of ordinary income and capital gains. Income distributions and capital
gain distributions are determined in accordance with income tax regulations
which may differ from generally accepted accounting principles. These
differences are primarily due to differing treatments of income and gains on
various investment securities held by the Fund, timing differences and differing
characterization of distributions made by the Fund.

For the year ended September 30, 1997, permanent differences resulting from book
and tax accounting for organizational costs were reclassified causing a decrease
of $4,460 to paid-in capital and an increase to undistributed net investment
income for the same amount.

Federal Income Taxes:

It is the Fund's policy to qualify as a regulated investment company by
complying with the requirements of the Internal Revenue Code of 1986, as
amended, applicable to regulated investment companies and by, among other
things, distributing substantially all of its taxable earnings to its
shareholders. Therefore, no Federal income tax provision is required.

3.  INVESTMENT ADVISORY, SUB-ADVISORY, ADMINISTRATION FEES AND OTHER
    TRANSACTIONS

On July 1, 1997, GWFC, the indirect parent of Sierra Advisors, the Fund's
current investment adviser, and Washington Mutual, Inc. ("WAMU"), a
publicly-held financial services company, consummated a previously announced
Agreement and Plan of Merger resulting in the merger of GWFC with and into a
wholly owned subsidiary of WAMU (the "Merger"). As a result of the Merger,
Sierra Advisors and its affiliates are now indirect subsidiaries of WAMU.


                                      -10-

<PAGE>   27
Sierra Advisors, an indirect wholly-owned subsidiary of WAMU, is the Fund's
investment advisor. Sierra Advisors is entitled to a monthly fee at an annual
rate of 0.95% of the average daily net assets of the Fund. These fees were
$102,711 for the year ended September 30, 1997 and have been voluntarily waived
by Sierra Advisors. Sierra Advisors pays a monthly fee at an annual rate of
0.475% to Van Kampen American Capital Management Inc. for services rendered as
the Sub-Advisor.

Sierra Fund Administration Corporation ("Sierra Administration") is the Fund's
administrator. Sierra Administration receives a monthly fee at an annual rate of
0.25% of the Fund's average daily net assets and the Fund pays First Data
Investor Services Group, Inc. ("First Data") directly for all transfer agent
services. The Administration fees for the year ended September 30, 1997 were
$27,029. Sierra Administration pays State Street Bank and Trust Company ("State
Street") for certain administrative and custodial services. The Fund pays for
the sub-administrator and custodial out-of pocket expenses.

The compensation of the officers and Trustees who are interested persons (as
defined in the 1940 Act) of the Advisor is paid by the Advisor or by its parent,
WAMU. The Fund pays the compensation of all other officers and Trustees of the
Fund. Trustees who are not interested persons are paid an annual fee of $5,000,
a fee of $1,000 per meeting of the Board of Trustees, a fee of $750 per
committee meeting of the Fund, and a fee of $1,000 per contract renewal meeting
of the Fund, plus expenses. The designated "Lead Trustee," because of increased
responsibilities, is paid 1 1/2 times the normal Trustee compensation for
meeting fees and retainer for the Fund, plus expenses.

Sierra Advisors has agreed to voluntarily reimburse the Fund's total operating
expenses. For the year ended September 30, 1997 the total reimbursement to the
Fund was $390,067.

For the year ended September 30, 1997, Great Western Financial Securities
Corporation and Sierra Investment Services Corporation ("SISC"), both registered
broker-dealers, have received $6,626 and $844, respectively, representing
commissions (front-end sales charges).

4. PURCHASE AND SALES OF SECURITIES

The aggregate cost of purchases and proceeds from sales of securities, excluding
U.S. Government and short-term investments, for the year ended September 30,
1997 was $1,025,217 and $3,925,221, respectively.

5. TENDER OF SHARES

The Board of Trustees of the Fund currently intends, each quarter, to consider
authorizing the Fund to make tender offers for a portion of its outstanding
Class A Common Shares at the then current net asset value of these Common
Shares. The Fund does not intend to list its Common Shares on any national
securities exchange and none of the Fund, the Advisor or SISC intends to make a
secondary trading market in the classes of the Common Shares at any time.
Accordingly, there is not expected to be any secondary trading market in the
Common Shares and an investment in such Common Shares should be considered
illiquid. There can be no assurance that the Fund will in fact tender for any of
its Common Shares. If the Fund tenders for Common Shares there is no guarantee
that all, or any, Common Shares tendered will be purchased. An early withdrawal
charge may be charged by SISC on those repurchases or tenders done during the
first or second year after purchase. For the year ended September 30, 1997,
503,732 shares were tendered and repurchased by the Fund with no early
withdrawal charge.


                                      -11-

<PAGE>   28
6. SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Fund to issue an unlimited number of full
and fractional Common Shares of beneficial interest with no par value. The Fund
initially is offering 5,000,000 Class A Common Shares in a continuous offering
pursuant to Rule 415 under the Securities Act of 1933, as amended.

7. ORGANIZATION COSTS

Expenses incurred in connection with the organization of the Fund, including the
fees and expenses of registering and qualifying its shares for distribution
under Federal and state securities regulations, are being amortized on a
straight-line basis over a period of five years from commencement of operations
of the Fund. In the event any of the initial shares of the Fund are redeemed by
any holder thereof during the amortization period, the proceeds of such
redemptions will be reduced by an amount equal to the pro-rata portion of
unamortized deferred organizational expenses in the same proportion as the
number of shares being redeemed bears to the number of initial shares of such
Fund outstanding at the time of such redemption. To the extent that proceeds of
the redemptions are less than such pro-rata portion of any unamortized
organizational expenses, Sierra Administration has agreed to reimburse the Fund.

8. SENIOR LOAN PARTICIPATIONS

The Fund invests primarily in participations, assignments, or acts as a party to
the primary lending syndicate of a Variable Rate Senior Loan interest to United
States corporations, partnerships, and other entities. When the Fund purchases a
participation of a Senior Loan interest, the Fund typically enters into a
contractual agreement with the lender or other third party selling the
participation, but not with the borrower directly. As such, the Fund assumes the
credit risk of the Borrower, Selling Participant or other persons
interpositioned between the Fund and the Borrower.

At September 30, 1997, the following sets forth the selling participants with
respect to interests in Senior Loans purchased by the Fund on a participation
basis.

9. LINE OF CREDIT

Sierra Prime Income Fund and the Sierra Trust Funds participate in a $40 million
line of credit provided by Deutsche Bank AG, New York Branch (the "Bank") under
a Credit Agreement (the "Agreement") dated May 22, 1996, primarily for temporary
or emergency purposes, including the meeting of redemption requests that
otherwise might require the untimely disposition of securities. Under the
Agreement, Sierra Prime Income Fund may borrow up to $433,000 plus its pro rata
portion of any unused base commitment allocation of the other borrowers under
the Agreement. Interest is payable at one of the following rates depending on
the type of loan designated by the borrower: (i) the higher of 0.50% in excess
of the Federal Funds Rate and the prime lending rate announced by the Bank; (ii)
the New York Interbank Offered Rate (NIBOR) plus 0.35% on an annualized basis;
or (iii) the London Interbank Offered Rate (LIBOR) plus 0.35% on an annualized
basis. The Fund is charged an aggregate commitment fee computed at a rate



                                      -12-
<PAGE>   29

equal to 0.05% on an annual basis of the daily average unutilized credit
balance. The Agreement requires that the aggregate outstanding principal amount
of the loan made shall not exceed 33 1/3 % of the value of the total assets of
the fund less all liabilities and indebtedness not represented by senior
securities. The Fund currently expects, however, to limit its borrowing to an
amount sufficient to meet its tender offer purchases or 15% of its assets,
whichever is greater. During the year ended September 30, 1997, the Fund had not
borrowed under the Agreement. As of October 27, 1997, a Second Amendment to the
Agreement was signed extending the Agreement to December 31, 1997.

10.  SUBSEQUENT EVENTS

The fifth tender offer for the fiscal year end September 30, 1997 commenced on
September 10, 1997 and expired on October 10, 1997. A total of 44,396 shares
were tendered to the Fund for repurchase.

A Special Meeting of Shareholders of the Fund (the "Special Meeting") to be held
on December 23, 1997 is being called in preparation for the planned
consolidation of the funds managed by Sierra Advisors and its affiliates,
including but not limited to the Fund, Sierra Trust Funds, The Sierra Variable
Trust and Sierra Asset Management Portfolios, and those managed by Composite
Research & Management Co. ("Composite"), which also is an indirect subsidiary of
Washington Mutual. The planned consolidation will result in a common Board and a
single investment adviser in Composite. Shareholders of record of the Fund on
October 29, 1997 will be entitled to vote at the Special Meeting.

On October 27-28, 1997, the Fund's Board of Trustees approved, subject to
shareholder approval, the following matters: (1) A proposal to elect a Board of
Trustees, (2) a proposal to approve a new Investment Management Agreement
between the Fund and Composite; and (3) a proposal to approve a new Investment
Sub-Advisory Agreement for the Fund between Composite and Van Kampen American
Capital Management, Inc. ("Van Kampen"). The Fund will also be entering into:
(a) a new administration agreement with Murphey Favre Securities Services, Inc.
("Murphey Favre"); (b) a new distribution agreement with Composite for the
purpose of replacing the current distributor, Sierra Investment Services
Corporation; and (c) a transfer agency and services agreements with Murphey
Favre for providing transfer agency services.

If the proposal to elect a Board of Trustees (Proposal 1) is approved, then the
Fund will increase the number of its Trustees from six to thirteen. If the
proposal to approve a new investment advisory agreement between the Fund and
Composite (Proposal 2) is approved, the investment advisory fees and total
operating expenses for the Fund will remain the same or decrease. If the
proposal to approve a new investment sub-advisory agreement with Van Kampen is
approved, the Fund will continue to receive investment sub-advisory services on
the same basis without change in the level of services and compensation received
by Van Kampen.

Sierra Prime Income Fund
Report of Independent Accountants


TO THE SHAREHOLDERS AND TRUSTEES
OF SIERRA PRIME INCOME FUND

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations, of
changes in net assets and of cash flows and the financial highlights present
fairly, in all material respects, the financial position of Sierra Prime Income
Fund (the "Fund") at September 30, 1997, the results of its operations, its cash
flows, the changes in its net assets and the financial highlights for the
periods indicated, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities owned at
September 30, 1997 by correspondence with the custodian, and with respect to
senior collateralized loans by correspondence with the selling participants and
agent banks, provide a reasonable basis for the opinion expressed above.

As explained in Note 2, the financial statements include senior collateralized
loans valued at $3,630,766 (43.1 percent of net assets), whose values have been
determined in accordance with procedures established by the Trustees in the
absence of readily ascertainable market values. Those values determined in
accordance with procedures established by the Trustees may differ significantly
from the values that would have been used had a ready market for the senior
collateralized loans existed, and the differences could be material to the
financial statements.

         authorizations, in either case signed exactly as such name(s) appear on
         the registration of the Class A Common Shares and such endorsements or
         authorizations must be guaranteed by an institution described in Box
         No. 3.

         (e) If this Letter of Transmittal or any authorizations are signed by
         trustees, executors, administrators, guardians, attorneys-in-fact,
         officers of corporations or others acting in a fiduciary or
         representative capacity, such persons should so indicate when signing
         and must submit proper evidence satisfactory to the Fund of their
         authority so to act. 

         (f) Your signature MUST be guaranteed and you MUST complete the
         signature guarantee in Box No. 3 if (i) the value of the Class A Common
         Shares tendered herewith pursuant to the Offer is greater than $50,000,
         (ii) this Letter of Transmittal is signed by someone other than the
         registered holder of the Class A Common Shares tendered herewith, or
         (iii) you request payment for the Class A Common Shares tendered
         herewith to be sent to a payee other than the registered owner of such
         Class A Common Shares and/or to an address other than the


<PAGE>   6
         registered address of the registered owner of the Class A Common
         Shares. An acceptable guarantee is one made by a commercial bank or
         trust company having an office, branch or agency in the United States,
         a member firm of a registered national securities exchange, a credit
         union or a savings association. The guarantee must state the words
         "Signature Guaranteed" along with the name of the granting institution.
         Shareholders should verify with the institution that it is an eligible
         guarantor prior to signing. A guarantee from a notary public is not
         acceptable.

     4. TRANSFER TAXES. The Fund will pay all share transfer taxes, if any,
     payable on the transfer to it of Class A Common Shares purchased pursuant
     to the Offer. If, however, (a) payment of the Purchase Price is to be made
     to any person other than the registered owner(s), (b) (in the circumstances
     permitted by the Offer) unpurchased Class A Common Shares are to be
     registered in the name(s) of any person other than the person(s) signing
     this Letter of Transmittal, the amount of any transfer taxes (whether
     imposed on the registered owner(s) or such other persons) payable on
     account of the transfer to such person(s) will be deducted from the
     Purchase Price by the Transfer Agent unless satisfactory evidence of the
     payment of such taxes, or exemption therefrom, is submitted.

     5. IRREGULARITIES. All questions as to the validity, form, eligibility
     (including time of receipt) and acceptance of any tender of Class A Common
     Shares will be determined by the Fund in its sole discretion, whose
     determination shall be firm and binding on all parties. The Fund reserves
     the absolute right to reject any or all tenders determined by it not to be
     in appropriate form or the acceptance of or payment for any Class A Common
     Shares which may, in the opinion of the Fund's counsel, be unlawful. The
     Fund also reserves the absolute right to waive any of the conditions of the
     Offer or any defect or irregularity in tender of any particular Class A
     Common Shares or any particular shareholder, and the Fund's interpretations
     of the terms and conditions of the Offer (including these Instructions)
     will be final and binding on all parties. Unless waived, any defects or
     irregularities in connection with tenders must be cured within such time as
     the Fund shall determine. Tendered Class A Common Shares will not be
     accepted for payment unless all defects and irregularities have either been
     cured within such time or waived by the Fund. None of the Fund, Sierra
     Investment Services Corporation, the Transfer Agent, the Administrator, or
     any other person shall be obligated to give notice of defects or
     irregularities in tenders, nor shall any of them incur any liability for
     failure to give any such notice.

     6. QUESTIONS AND REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions
     and requests for assistance may be directed to, and additional copies of
     the Offer to Purchase and this Letter of Transmittal may be obtained from
     Sierra Shareholder Services located at 9301 Corbin Avenue, Suite 333,
     Northridge, California 91324, or by telephoning (800) 222-5852.

     7. FORM W-9. Each tendering shareholder who has not already submitted a
     completed and signed Form W-9 to the Fund is required to provide the
     Transfer Agent with a correct taxpayer identification number ("TIN") on
     Form W-9 which is enclosed herewith. Failure to provide the information on
     the form may subject the tendering shareholder to 31% federal income tax
     withholding on the payments made to the shareholder or other payee with
     respect to Class A Common Shares purchased pursuant to the Offer.

     8. WITHHOLDING ON FOREIGN SHAREHOLDERS. The Transfer Agent will withhold
     federal income taxes equal to 30% of the gross payments payable to a
     foreign shareholder unless the Transfer Agent determined that a reduced
     rate of withholding or an exemption from withholding is applicable. For
     this purpose, a foreign shareholder is any shareholder that is not (i) a
     citizen or resident of the United States, (ii) a corporation, partnership
     or other entity created or organized in or under the laws of the United
     States or any political subdivision thereof, or (iii) any estate or trust
     the income of which is subject to United States federal income taxation
     regardless of the source of such income. The Transfer Agent will determine
     a shareholder's status as a foreign shareholder and eligibility for a
     reduced rate of, or an exemption from, withholding by reference to the
     shareholder's address or statements concerning eligibility for a reduced
     rate of, or exemption from, withholding unless facts and circumstances
     indicate that reliance is not warranted. A foreign shareholder who has not
     previously submitted the appropriate statements with respect to a reduced
     rate of, or an exemption from, withholding for which such shareholder may
     be eligible should consider doing so in order to avoid overwithholding. A
     foreign shareholder may be eligible to obtain a refund of tax withheld if
     such shareholder meets one of the three tests for capital gain or loss
     treatment described in Section 15 of the Offer to Purchase or is otherwise
     able to establish that no tax or a reduced amount of tax was due.

     IMPORTANT: THE LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE OF IT
     (TOGETHER WITH ALL OTHER REQUIRED DOCUMENTS) MUST BE RECEIVED BY THE
     ADMINISTRATOR ON OR BEFORE THE EXPIRATION DATE.

     To Our Authorized Dealers:

          As you may be aware, it is the policy of the Board of Trustees of the
     Sierra Prime Income Fund to consider on a quarterly basis whether to make a
     tender offer for the Class A Common Shares of the Fund. We are pleased to
     announce that the Board has authorized a quarterly tender offer of the
     Fund's shares commencing today, December 10, 1997, for the purpose of
     providing liquidity to its shareholders. The commencement of the tender
     offer was announced in the Wall Street Journal today.

          The Fund is offering to purchase up to 161,925 of its Class A Common
     Shares (approximately 20% of its issued and outstanding Class A Common
     Shares) for cash at a price equal to the net asset value per Class A Common
     Shares of the Fund determined as of 2:00 PM Pacific Standard Time on the
     Expiration Date of the Offer. The Offer is scheduled to terminate as of
     6:00 PM Pacific Standard Time on January 9, 1998, the expiration date of
     the offer (unless extended). An "Early Withdrawal Charge" or "EWC" may be
     imposed on certain Class A Common Shares accepted for payment that have
     been held for less than two years.

     CREDIT AGREEMENT, dated as of May 22, 1996, among the entities listed on
the signature pages hereto (each a "Borrower" and collectively the "Borrowers"),
and Deutsche Bank AG, New York Branch (together with its successors and assigns,
the "Bank"; all capitalized terms used herein and defined in Section 9 are used
herein as therein defined).

                              W I T N E S S E T H :

     WHEREAS, subject to and upon the terms and conditions herein set forth, the
Borrowers may request that the Bank make available the credit facilities
provided for herein;

     NOW, THEREFORE, IT IS AGREED:

     SECTION 1. Amount and Terms of Credit.

     1.01 The Commitment. (a) Subject to and upon the terms and conditions set
forth herein, the Bank agrees, at any time and from time to time on and after
the Effective Date and prior to the Expiry Date, at the request of a Borrower,
to make Loans (each a "Loan" and, collectively, the "Loans") to such Borrower,
which Loans (i) shall, at the option of such Borrower, be Base Rate Loans, LIBOR
Loans or NIBOR Loans, provided that all Loans comprising the same Borrowing
shall at all times be of the same Type, (ii) may be repaid and reborrowed in
accordance with the provisions hereof, and (iii) shall not exceed for any
particular Borrower the lesser of such Borrower's Borrowing Base and, when
aggregated with all Loans then outstanding, the commitment. If more than one
Borrower desires to make a Borrowing on any Business Day, each Borrower, subject
to the terms and conditions contained herein, shall have the right to obtain up
to the amount specified on Schedule I, shall have the right to obtain up to the
amount specified on Schedule I (the "Base Commitment") and to the extent that
any Borrower has not requested its Base Commitment, the unused portion shall be
available to other Borrowers on a pro rata basis in proportion to their Base
Commitment. The Borrowers may from time to time revise their Base Commitment if
approved by the Board of Trustees of each Borrower and a copy of any such
revisions is furnished to the Bank whereupon Schedule I hereto shall be deemed
modified to reflect such revisions; provided, however, that the total of the
base Commitments shall not exceed the lesser of the Commitment and, for any
particular Borrower, such Borrower's Borrowing Base. Any revisions to the Base
Commitment shall become effective upon written notice to the Bank from the
Investment Advisor on behalf of the Borrowers.

     1.02 Minimum Amount of Each Borrowing. The aggregate principal amount of
each Borrowing shall not be less than $50,000 and, if greater, shall be in an
integral multiple of $10,000. More than one Borrowing may occur on the same
date.

     1.03 Notice of Borrowing. Whenever the Borrower desires to make a Base Rate
or NIBOR Borrowing hereunder, it shall give the Bank as its Notice Office notice
of its intention to borrow before 12:00 p.m. (New York time) on the Business day
on which it desires to incur such Loan. Whenever the Borrower desire to make a
LIBOR Borrowing hereunder it shall give the Bank at its Notice Office notice of
its intention to borrow at least three Business Days' prior to the Business Day
on which such Loan is to be made, provided that any such notice shall be deemed
to have been given on a certain day only if given before 12:00 Noon (New York
time) on such day. All such notices relating to Base Rate, LIBOR and NIBOR
borrowings (each a "Notice of Borrowing") shall be in the form of Exhibit A,
appropriately completed to specify (a) the identity of such Borrower, (b) the
aggregate principal amount of the Loans to be made pursuant to such Borrowing,
(c) the Business Day on which such Loans are to be made, (d) whether such Loans
are to be Base Rate Loans, LIBOR Loans or NIBOR Loans, (e) the aggregate amount
of principal and interest on outstanding Loans which are payable by such
Borrower on such date; (f) if the amount specified pursuant to clause (b) is
greater than the amount specified pursuant to clause (e), the net amount to be
remitted by the Bank pursuant to Section 1.04 at the time the Bank makes the
Loan and (g) if the amount specified pursuant to clause (e) is greater than the
amount specified pursuant to clause (b), the net amount to be remitted by such
Borrower pursuant to Section 2.02.

     1.04 Disbursement of Funds. The Bank will make funds available to the
relevant Borrower in an amount equal to the net amount, if any specified in the
related Notice of Borrowing pursuant to Section 1.03(g) by a wire transfer,
initiated no later than 2:00 P.M. New York time on the date specified in the
Notice of Borrowing, of immediately available funds to an account specified by
or on behalf of such Borrower.


<PAGE>   6
     1.05 Notes. Each Borrower's obligation to pay the principal of, and
interest on, the Loans made to it by the Bank shall be evidenced by a promissory
note duly executed and delivered by such Borrower substantially in the form of
Exhibit B, with blanks appropriately completed in conformity herewith (each a
"Note" and collectively the "Notes"). The Note shall (i) be executed by the
relevant Borrower, (ii) be payable to the Bank and be dated the Effective Date,
(iii) be in a stated principal amount of the Loans evidenced thereby, (iv) bear
interest as provided in the appropriate clause of Section 1.07 in respect of the
Base Rate Loans, LIBOR Loans or NIBOR Loans, as the case may be, evidenced
thereby, (vi) be subject to mandatory repayment as provided in Section 2.01 and
(vii) be entitled to the benefits of this Agreement and the other Credit
Documents.

     1.06 Bank Notations. The Bank will note on its internal records the amount
of each Loan made by it to a Borrower and each payment in respect thereof and
will prior to any transfer of any of its Notes endorse on the reverse side
thereof the outstanding principal amount of Loans evidenced thereby. Failure to
make any such notation shall not affect such Borrower's obligations in respect
of such Loans.

     1.07 Interest. (a) Each Borrower agrees to pay interest in respect of the
unpaid principal amount of each Base Rate Loan made to it from the date the
proceeds thereof are made available to such Borrower until the maturity thereof
(whether by acceleration, demand or otherwise) at a rate per annum which shall
be equal to the Base Rate in effect from time to time.

     (b) Each Borrower agrees to pay interest in respect of the unpaid principal
amount of each NIBOR Loan made to it from the date the proceeds thereof are made
available to such Borrower until the maturity thereof (whether by acceleration,
demand or otherwise) at a rate per annum shall, during each Interest Period
applicable thereto, be equal to the sum of the NIBOR Rate for such Interest
Period plus 35% of 1%.

     (c) Each Borrower agrees to pay interest in respect of the unpaid principal
amount of each LIBOR Loan made to it from the date the proceeds thereof are made
available to such Borrower until the maturity thereof (whether by acceleration,
demand or otherwise) at a rate per annum which shall, during each Interest
Period applicable thereto, be equal to the sum of the LIBOR Rate for such
Interest Period plus 35% of 1%.

     (d) Overdue principal and, to the extent permitted by law, overdue interest
in respect of each Loan and other overdue amount payable hereunder shall, in
each case, bear interest at a rate per annum equal to the greater of (x) 2% per
annum in excess of the rate otherwise applicable to Loans maintained as Base
Rate Loans from time to time or (y) the rate which is 2% in excess of the rate
then borne by such Loans, in each case with such interest to be payable on
demand by the relevant Borrower.

     (e) Accrued (and therefore unpaid) interest shall be payable (i) in respect
of each Base Rate Loan, quarterly in arrears on the last Business Day of March,
June, September and December; (ii) in respect of each Fixed Rate Loan, on the
last day of each Interest Period applicable thereto and (ii) in respect of each
Loan, on any repayment or prepayment (on the amount repaid or prepaid), at
maturity (whether by acceleration, demand or otherwise) and, after such
maturity, on demand.

     (f) Upon each Interest Determination Date, the Bank shall determine the
interest rate for the Fixed Rate Loans, for which such determination is being
made and shall promptly notify the relevant Borrower thereof. The Bank shall
make such determination promptly following its determination to make a Loan
hereunder. Each determination of the interest rate shall, absent manifest error,
be final and conclusive and binding on all parties hereto.

     1.08 Interest Periods. At the time it gives any Notice of Borrowing in
respect of the making of any Fixed Rate Loan, each Borrower shall have the right
to elect, by giving the Bank notice thereof, the interest period (each an
"Interest Period") applicable to such Fixed Rate Loan, which Interest Period
shall, at the option of such Borrower, in the case of a LIBOR Loan, be a one,
two, three or six month period, and in the case of a NIBOR Loan be a period of
up to thirty days, provided that: (i) all Fixed Rate Loans comprising a
Borrowing shall at all times have the same Interest Period; (ii) the initial
Interest Period for any Fixed Rate Loan shall commence on the date of Borrowing
of such Loan (including the date of any conversion thereof into a Loan of
different Type) and each Interest Period occurring thereafter in respect of such
Loan

                                       -2-

<PAGE>   7
shall commence on the day on which the next preceding Interest Period applicable
thereto expires; (iii) if any Interest Period relating to a Fixed Rate Loan
begins on a day for which there is no numerically corresponding day in the
calendar month at the end of such Interest Period, such Interest Period shall
end on the last Business Day of such calendar month; (iv) if any Interest Period
would otherwise expire on a day which is not a Business Day, such Interest
Period shall expire on the next succeeding Business Day, provided that if any
Interest Period for a LIBOR Loan would otherwise expire on a day which is not a
Business Day but is a day of the month after which no further Business Day
occurs in such month, such Interest Period shall expire on the next preceding
Business Day; (v) no Interest Period shall extend beyond the Expiry Date. If
upon the expiration of any Interest Period applicable to a Fixed Rate Loan, the
Borrower has failed to elect a new Interest Period to be applicable to such
Fixed Rate Loan as provided above, the Borrower shall be deemed to have elected
to convert such Loan into a Base Rate Loan effective as of the expiration date
of such current Interest Period.

     1.09 Compensation. Each Borrower shall compensate the Bank, upon its
written request (which request shall set forth the basis for requesting such
compensation), for all reasonable losses, expenses and liabilities (including,
without limitation, any loss, expense or liability incurred by reason of the
liquidation or reemployment of deposits or other funds required by the Bank to
fund its Fixed Rate Loans) which such Bank may sustain: (i) if for no reason
(other than the Bank's failure to make a loan) a Borrowing of Fixed Rate Loans
does not occur on a date specified therefor in a Notice of Borrowing; (ii) if
any repayment (including any repayment made pursuant to Section 2 or a result of
any demand made by the Bank or an acceleration of the Loans pursuant to Section
8) of any of its Fixed Rate Loans occurs on a date which is not the last day of
an Interest Period with respect thereto; or (iii) as a consequence of any other
default by such Borrower to repay its Loans when required by the terms of this
Agreement or any Note held by the Bank.

     1.10 Increased Costs, Illegality, etc. (a) In the event that the Bank shall
have determined (which determination shall, absent manifest error, be final and
conclusive and binding upon all parties hereto): (i) on any Interest
Determination Date that, by reason of any changes arising after the date of this
Agreement affecting the interbank market, adequate and fair means do not exist
for ascertaining the applicable interest rate on the basis provided for in the
definition of NIBOR or LIBOR; or (ii) at any time, that the Bank shall incur
increased costs or reductions in the amounts received or receivable hereunder
with respect to any Fixed Rate Loan because of any change since the date of this
Agreement in any applicable law or governmental rule, regulation, order or
request (whether or not having the force of law) (or in the interpretation or
administration thereof and including the introduction of any new law or
governmental rule, regulation, order or request), such as, for example, but not
limited to, (A) a change in the basis of taxation of payments to the Bank or its
applicable lending office of the principal of or interest on the Notes or any
other amounts payable hereunder (except for changes in the rate of tax on, or
determined by reference to, the net income or profits of the Bank or its
applicable lending office imposed by the jurisdiction in which principal office
or applicable lending office is located) or (B) a change in official reserve
requirements, but, in all events, excluding reserves required under Regulation D
to the extent covered by Section 1.10(d) or included in the computation of NIBOR
or LIBOR; or (iii) at any time, that the making or continuance of any Fixed Rate
Loan has been made (x) unlawful by an law or governmental rule, regulation or
order, or (y) impossible by compliance by the Bank with any governmental request
(whether or not having force of law); then, and in any such event, the Bank
shall promptly give notice (by telephone confirmed in writing) to each of the
Borrowers. Thereafter (x) in the case of clause (i) above, the Fixed Rate Loans
shall no longer be available until such time as the Bank notifies the Borrowers
that the circumstances giving rise to such notice by the Bank no longer exist,
and any Request for Borrowing given by a Borrower with respect to Fixed Rate
Loans which have not yet been incurred shall be deemed rescinded by such
Borrower; (y) in the case of clause (ii) above, each relevant Borrower shall pay
to the Bank, within two Business Days after written demand therefor, such
additional amounts (in the form of an increased rate of, or a different method
of calculating, interest or otherwise as the Bank in its sole discretion shall
determine) as shall be required to compensate the Bank for such increased costs
or reductions in amounts received or receivable hereunder (a written notice as
to the additional amounts owed to the Bank, showing the basis for the
calculation thereof, submitted to each of the relevant Borrowers by the Bank
shall be conclusive, absent manifest error); and (z) in the case of clause (iii)
above, taken one of the actions specified in Section 1.10(b) as promptly as
possible and, in any event, within the time period required by law.

     (b) At any time that any Fixed Rate Loan is affected by the circumstances
described in Section 1.10(a)(ii) or (iii), each relevant Borrower may (and, in
the case of a Fixed Rate Loan affected by the circumstances described in Section
1.10(a)(iii), shall) either (i) if the affected Fixed Rate Loan is then being
made initially or pursuant to a conversion, cancel said Borrowing, or change the
Type of Loan to become a Base Rate Loan by giving the Bank notice by telephone
(confirmed

                                       -3-

<PAGE>   8
in writing) of the cancellation on the same date (if practicable) that such
Borrower was notified by the Bank pursuant to Section 1.10(a)(ii) or (iii); or
(ii) if the affected Loan is then outstanding, upon at least three Business
Days' written notice, require the Bank to convert such Fixed Rate Loan into a
Base Rate Loan.

     (c) If the Bank determines at any time that any change since the date of
this Agreement in any applicable law or governmental rule, regulation, order or
request (whether or not having the same force of law) concerning capital
adequacy, or any change since the date of this Agreement in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency, will have the effect of increasing the amount of capital
required or expected to be maintained by the Bank based on the existence of the
Bank's obligations hereunder, then the Borrowers shall pay to the Bank, upon its
written demand therefor, such additional amounts as shall be required to
compensate the Bank for the increased cost to the Bank as a result of such
increase of capital. The Bank, upon determining that any additional amounts will
be payable pursuant to this Section 1.10(c), will give prompt written notice
thereof to the Borrowers, which notice shall show the basis for calculation of
such additional amounts. In determining such additional amounts, the Bank will
act reasonably and in good faith and will use averaging and attribution methods
that are reasonable; provided that the Bank's determination of compensation
owing under this Section 1.10(c) shall be conclusive, absent manifest error.

     (d) In the event that the Bank shall determine (which determination shall
be prima facie evidence with respect to all the parties hereto) at any time that
by reason of Regulation D the Bank's lending office is required to maintain
reserves in respect of Eurocurrency liabilities (as defined in Regulation D)
during any period in which it has a Fixed Rate Loan outstanding (each such
period, for the Bank, a "Eurocurrency Reserve Period"), then the Bank shall
promptly give notice (by telephone confirmed in writing) to the Borrowers of
such determination, and the Borrowers shall pay to the Bank additional interest
on the unpaid principal amount of each Fixed Rate Loan of the Bank during such
Eurocurrency Reserve Period at a rate per annum which shall, during each
Interest Period applicable to such Fixed Rate Loan, be the amount by which (i)
the NIBOR or LIBOR for such Interest Period divided (and rounded to the nearest
whole multiple of 1/16 of 1%) by a percentage equal to 100% minus the then
maximum rate of all reserve requirements (including, without limitation, any
marginal, emergency, supplemental, special or other reserves) applicable to any
member bank of the Federal Reserve System in respect of Eurocurrency liabilities
(as defined in Regulation D) exceeds (ii) the NIBOR or LIBOR for such Interest
Period. Additional interest payable pursuant to the immediately preceding
sentence shall be paid by each such relevant Borrower at the time that it is
otherwise required to pay interest in respect of such Fixed Rate Loan. The Bank
agrees that if it gives notice to the Borrowers of the existence of a
Eurocurrency Reserve Period, it shall promptly notify the Borrowers of any
termination thereof, at which time the Borrowers shall cease to be obligated to
pay additional interest to such Bank pursuant to the first sentence of this
Section 1.10(d) until such time, if any, as a subsequent Eurocurrency Reserve
Period shall occur.

     SECTION 2. Prepayments; Payments; Fees.

     2.01 Repayments. (a) On any day on which the aggregate outstanding
principal amount of Loans made to a Borrower when aggregated with all Loans then
outstanding exceeds the Commitment as then in effect, such Borrower shall prepay
principal of Loans in an amount equal to such excess.

     (b) If on any date the aggregate outstanding principal amount of Loans made
to a Borrower exceeds such Borrower's Borrowing Base, such Borrower shall
promptly (and in any event within 2 Business Days) after the occurrence of such
date, prepay principal of Loans in an amount equal to such excess.

     (c) Each Borrower shall have the right to prepay the Loans made to it,
subject to Section 1.09, in whole or in part at any time and from time to time
on the following terms and conditions: (i) such Borrower shall give the Bank
prior to 11:00 A.M. (New York time) (x) at least one Business Days' prior
written notice (or telephonic notice promptly confirmed in writing) of its
intent to prepay Base Rate Loans on such Business Day) and (y) at least Two
Business Days' prior written notice (or telephonic notice promptly confirmed in
writing) of its intent to prepay Fixed Rate Loans, the amount of such prepayment
and the Types of Loans to be prepaid and, in the case of Fixed Rate Loans the
specific Borrowing or Borrowings pursuant to which made, and (ii) each
prepayment shall be in an aggregate principal amount of at least US$100,000.00.


                                       -4-

<PAGE>   9
     (d) Notwithstanding anything to the contrary contained elsewhere in this
Agreement, each Borrower shall repay the outstanding principal amount of each
Loan made to it on the last day of the Interest Period for such Loan and all
then outstanding Loans shall be repaid in full on the Expiry Date.

     2.02 Method and Place of Payment. Except as otherwise specifically provided
herein, all payments shall be made in Dollars in immediately available funds at
the Payment Office of the Bank no later than 2:30 P.M. (New York time) on the
date such payments are due. In the event that, on any date on which a payment of
principal or interest is due on a Loan to a Borrower, the Bank elects to make a
new Loan to such Borrower pursuant to the terms hereof, such Borrower shall only
be obligated to remit to the Bank an amount equal to the difference, if a
positive number, between the amount of such payment of principal and interest
less the amount of the new Loan. Whenever any payment to be made hereunder or
under any Note shall be stated to be due on a day which is not a Business Day,
the due date thereof shall be extended to the next succeeding Business Day and,
with respect to payments of principal, interest shall be payable at the
applicable rate during such extension.

     2.03 Fees. Each Borrower agrees to pay to the Bank on a pro rate basis (or
such other basis as shall be permitted by the Investment company Act and
approved by the Board of Trustees of each Borrower as the Investment Advisor on
behalf of the Borrowers may specify to the Bank from time to time in writing)
calculated according to its average net assets (as may be adjusted based on such
Borrower's Base Commitment and any other factors permitted by the Investment
Company Act) a commitment fee (the "Commitment Fee") for the period from the
Effective Date until the Expiry Date (or such earlier date as the Commitment
shall have terminated) computed at a rate equal to 1/20 of 1% per annum on the
daily average Unutilized Commitment of the Bank. Accrued Commitment Fees shall
be due and payable quarterly in arrears on the last Business Day of each March,
June, September and December of each year and on the Expiry Date or upon such
earlier date as the Commitment shall be terminated.

     2.04 Voluntary Termination of the Unutilized Commitment. Upon at least five
Business Days' prior notice to the Bank at its Notice Office, any Borrower (with
the unanimous consent of each Borrower hereunder) shall have the right, without
premium or penalty, to terminate the Unutilized Commitment in whole or in part,
in integral multiples of $5,000,000.

     2.05 Expiry Date. The expiration of the Commitment of the Bank shall be 364
days from the Effective Date (the "Expiry Date"); provided, however, that before
(but not earlier than 120 days nor later than 90 days before) each anniversary
of the Effective Date, the Borrowers may make a written request (an "Extension
Request") to the Bank at its Notice Office that the Expiry Date be extended by
364 days. Such Extension Request shall include a certification by a senior
officer of each of the Borrowers that no Default or Event of Default has
occurred and is continuing and all representations and warranties contained
herein and the other Credit Documents are true and correct in all material
aspects on and as of the date of the extension Request (it being understood and
agreed that any representation or warranty which expressly refers by its terms
to a specified date shall be required to be true only as of such date). If the
Bank agrees thereto, "Expiry Date" shall mean the day 364 days following the
Expiry Date then in effect, provided that any failure by the Bank to notify the
Borrower shall be deemed to be a disapproval by the Bank of the Borrower's
Extension Request. The Bank shall not be obligated to grant any extension
pursuant to this Section 2.05 and any such extension shall be in the sole
discretion of the Bank. The Borrowers shall pay to the Bank if it does not so
agree all amounts owing under the Notes and this Agreement on the Expiry Date or
upon the termination of the Bank's Commitment. In the event of any extension
pursuant to this Section 2.05, each Borrower shall be deemed to have represented
and warranted on and as of the effective date of such extension that no Default
or Event of Default has occurred and is continuing and all representations and
warranties contained herein and the other Credit Documents are true and correct
in all material respects on and as of the date of such extension (it being
understood and agreed that any representation or warranty which expressly refers
by its terms to a specified date shall be required to be true only as of such
date).

have received a Notice of Borrowing meeting the requirements of Section 1.03.

The acceptance of the proceeds of each Loan shall constitute a representation

shall be delivered to the Bank at its Notice Office and shall be in form and
substance satisfactory to the Bank (it being understood and agreed that the

shall be dated as of the Effective Date).

     SECTION 5. Representations, Warranties and Agreements. In order to induce
the Bank to enter into this Agreement and to make the Loans, each Borrower makes
the following representations, warranties and agreements as to itself, all of
which shall survive the execution and delivery of this Agreement and the Notes
and the making of the Loans, with the incurrence of each Loan on or after the
Initial Borrowing Date being deemed to constitute a representation and warranty
that the matters specified in this Section 5 are true and correct on and as of
the Effective Date and on the date of each such Loan:

validly existing trust, series of a trust or corporation in good standing under

property or the conduct of its business requires such qualifications except for
failures to be so qualified which, individually or in the aggregate, could not

operations, property, assets, liabilities, condition (financial or otherwise) or
prospects of such Borrower.

     5.02 Power and Authority. Such Borrower has the power and authority to
execute, deliver and perform the terms and provisions of each of the Credit
Documents and has taken all necessary corporate action to authorize the
execution, delivery and performance by it of each of the Credit Documents. Such
Borrower has duly executed and delivered each of the Credit Documents to which
it is a party, and each of the Credit Documents constitutes its legal, valid and
binding obligation enforceable against it in accordance with its terms, except
to the extent that the enforceability thereof may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws
generally affecting creditors' rights and by equitable principles (regardless of
whether enforcement is sought in equity or at law).

     5.03 No Violation. To the best of such Borrower's after due inquiry,
neither the execution, delivery or performance (including such Borrowing of
Loans hereunder) by any Borrower of any of the Credit Documents, nor compliance
by it with the terms and provisions thereof, (i) will contravene any provision
of any law, statute, rule or regulation (including, without limitation, the
Investment Company Act) which may result in any adverse effect on the legality,
validity or enforceability of any Credit Document or any order, writ, injunction
or decree of any court or governmental instrumentality, (ii) will conflict with
or result in any breach of any of the terms, covenants, conditions or provisions
of, or constitute a default under, or result in the creation or imposition of

assets of any Borrower pursuant to the terms of any indenture, mortgage, deed of
trust, credit agreement or loan agreement material to the business, operations,
property, assets, liabilities, condition (financial or otherwise) or prospects
of such Borrower, or any other material agreement, contract or instrument to
which such Borrower is a party or by which it or any of its property or assets
is bound or to which it may be subject or (iii) will violate or conflict with
any material portion of its Investment Practices or any material provision of
the Articles of Incorporation, By-Laws or Declaration of Trust of such Borrower.

     5.04 Governmental Approvals. No order, consent, approval, license,
authorization or validation of, or filing, recording or registration with

remain in full force and effect), or exemption by, any governmental or public
body or authority, or any subdivision thereof, is required to authorize, or is
required in connection with, (i) the execution, delivery and performance by such
Borrower of any such Credit Document to which it is a party or (ii) the
legality, validity, binding effect or enforceability of any such Credit
Document.

prospects of such Borrower that would materially and adversely affect its
ability to perform its obligations hereunder).

pursuant to Section 5.05(a), there were as of the Effective Date no liabilities
or obligations with respect to such Borrower of any nature whatsoever (whether
absolute, accrued, contingent or otherwise and whether or not due) which, either
individually or in aggregate, would be materially adverse to such Borrower. As
of the Effective Date, no Borrower knows of any basis for the assertion against
it of any liability or obligation of any nature whatsoever that is not fully
disclosed in the financial statements delivered pursuant to Section 5.05(a)
which, either individually or in the aggregate, would be materially adverse to
such Borrower.

     5.06 Litigation. There are no actions, suits or proceedings pending or, to
the best knowledge of such Borrower after due inquiry, threatened against such
Borrower (i) with respect to any Credit Document or (ii) that could reasonably
be expected to materially and adversely affect the business, operations,
property, assets, liabilities, condition (financial or otherwise) or prospects
of such Borrower.

whole) furnished by or on behalf of such Borrower in writing to the Bank
(including, without limitation, all information contained in the Credit
Documents) for purposes of or in connection with this Agreement, the other
Credit Documents or any transaction contemplated herein or therein is, and all
other such factual information (taken as a whole) hereafter furnished by or on
behalf of such Borrower in writing to the Bank will be, true and accurate in all
material respects on the date as of which such information is dated or certified

information (taken as a whole) not misleading in any material respect at such
time in light of the circumstances under which such information was provided.

     5.08 Use of Proceeds; Margin Regulations. (a) The proceeds of all Loans
shall be utilized by such Borrower to repay Loans outstanding hereunder and to
finance temporarily until settlement the sale or purchase of portfolio
securities by such Borrower, the repurchase or redemption of shares of such

emergency purposes.

violate or be inconsistent with the provisions of Regulations G, T, U or X of
the Board of Governors of the Federal Reserve System.

     5.09 ERISA. No Borrower nor any ERISA Affiliate has ever maintained or been
obligated to contribute to any "employee benefit plan" (as defined in Section
3(3) of ERISA).

     5.10 Compliance with Statutes, etc. Such Borrower is in compliance with (i)
all applicable statutes (including, without limitation, the Investment Company
Act), regulations and orders of, and all applicable restrictions imposed by, all
governmental bodies, domestic or foreign, in respect of the conduct of its
business and the ownership of its property, except such noncompliance as could
not, individually or in the aggregate, reasonably be expected to have a material
adverse effect on the business, operations, property, assets, liabilities,
condition (financial or otherwise) or prospects of such Borrower or any adverse
effect an the legality, validity or enforceability of this Agreement or any of
the other Credit Documents and (ii) all material investment policies and
restrictions set forth in its Articles of Incorporation, By-Laws or Declaration
of Trust, as applicable, and Investment Practices.

     5.11 Investment Company. Such Borrower is duly registered under the
Investment Company Act as in the case of Sierra Prime Income Trust a closed-end
management investment company and in the case of each other Borrower as a

                                       -8-

series of an open-end management investment company, and such registration has

     5.13 Affiliation with the Bank. Neither such Borrower nor any Affiliated
Person of such Borrower is an Affiliated Person of the Bank.

     5.14 Senior Status. The Indebtedness of each Borrower hereunder ranks pari
passu with all other Indebtedness of such Borrower other than Indebtedness
secured by Liens permitted under Section 7.01.

Agreement and the other Credit Documents and the documents and instruments
referred to herein and therein (including, without limitation, the reasonable
fees and disbursements of counsel for the Bank).

under applicable law or otherwise, and not by way of limitation of any such
rights, upon the occurrence of an Event of Default, the Bank is hereby
authorized at any time or from time to time, without presentment, demand,

under any of the other Credit Documents, including, without limitation, all
interests in Obligations purchased by the Bank pursuant to Section 10.04(b), and
all other claims of any nature or description arising out of or connected with
this Agreement or any other Credit Document, irrespective of whether or not the
Bank shall have made any demand hereunder and although said Obligations,
liabilities or claims, or any of them, shall be contingent or unmatured.

and other communications provided for hereunder shall be in writing (including
telegraphic, telex, telecopier or cable communication) and mailed, telegraphed,

rights hereunder, the Bank shall remain a "Bank" for all purposes hereunder (and
may not transfer or assign all or any portion of its Loans hereunder except as
provided in Section 10.04(b)) and the transferee, assignee or participant, as
the case may be, shall not constitute a "Bank" hereunder and, provided further,
that the Bank shall not transfer or grant any participation without each
Borrower's consent and in any event shall not transfer or grant any
participation under which the participant shall have rights to approve any
amendment to or waiver of this Agreement or any other Credit Document except to
the extent such amendment or waiver would (i) extend the final scheduled
maturity of any Loan or Note in which such participant is participating, or
reduce the rate or extend the time of payment of interest thereon (except in
connection with a waiver of applicability of any post-default increase in
interest rates) or reduce the principal amount thereof, or increase the amount
of the participant's participation over the amount thereof then in effect, or
(ii) consent to the assignment or transfer by a Borrower of any of its rights
and obligations under this Agreement. In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the other
Credit Documents (the participant's rights against the Bank in

                                      -18-

<PAGE>   23
respect of such participation to be those set forth in the agreement executed by
such Bank in favor of the participant relating thereto) and all amounts payable
by the Borrowers hereunder shall be determined as if such Bank had not sold such
participation.

     (b) Notwithstanding the foregoing, the Bank may (x) assign all or a portion
of its Loans, rights and related outstanding Obligations hereunder to its parent
company and/or any affiliate of such Bank or to any one or more Banks, provided
that any such assignee is a bank (as defined in the Investment Company Act) or
(y) with the consent of each Borrower assign all or a portion of such Loans,
rights and Obligations to one or more Eligible Transferees, each of which
assignees shall become party to this Agreement as a Bank by execution of an
Assignment and Assumption Agreement, provided that (i) at such time the Banks
and the Borrower shall modify this Agreement to the extent necessary to effect
such assignment and (ii) new Notes will be issued, at the Borrowers' expense, to
such new Bank and to the assigning Bank upon the request of such new Bank or
assigning Bank, such new Notes to be in conformity with the requirements of
Section 1.05. To the extent of any assignment pursuant to this Section 10.04(b),
the assigning Bank shall be relieved of its obligations hereunder with respect
to its assigned Loans, rights and Obligations.

     (c) Notwithstanding anything to the contrary contained above, in connection
with any participation or assignment pursuant to preceding Sections 10.04(a) or
(b), the Bank granting the assignment or participation shall, in the agreement
with respect thereto, obtain a representation from the participant or assignee
to the effect that it is not an Affiliated Person of any Borrower or an
Affiliated Person of such an Affiliated Person of any Borrower.

     (d) Nothing in this Agreement shall prevent or prohibit the Bank from
pledging its Loans and Notes hereunder to a Federal Reserve Bank in support of
borrowings made by the Bank from such Federal Reserve Bank.

     (e) Each Borrower hereby acknowledges and agrees that the Bank may share
with any of its affiliates any information related to such Borrower and its
affiliates (including, without limitation, any non-public customer information
regarding the creditworthiness of such Borrower and its affiliates), provided
that such affiliate shall keep any such information confidential in accordance
with its customary banking procedures.

     10.05 No Waiver; Remedies Cumulative; Recourse.

     No failure or delay on the part of the Bank or any holder of any Note in
exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between any Borrower and the Bank or the
holder of any Note shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder or under any other
Credit Document preclude any other or further exercise thereof or the exercise
of any other right, power or privilege hereunder or thereunder. The rights,
powers and remedies herein or in any other Credit Document expressly provided
are cumulative and not exclusive of any rights, powers or remedies which the
Bank or the holder of any Note would otherwise have. No notice to or demand on a
Borrower in any case shall entitle such Borrower to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the rights
of the Bank or the holder of any Note to any other or further action in any
circumstances without notice or demand.

     10.06 Calculations; Computations. (a) The financial statements to be
furnished to the Bank and the calculation of Asset Coverage Ratios and Borrowing
Base pursuant hereto shall be made and prepared in accordance with generally
accepted accounting principles in the United States consistently applied
throughout the periods involved (except as set forth in the notes thereto or as
otherwise disclosed in writing by the relevant Borrower to the Bank); provided
that, except as otherwise specifically provided herein, all computations
determining compliance with Section 6, shall utilize accounting principles and
policies in conformity with those used to prepare the historical financial
statements delivered to the Bank pursuant to Section 5.05(a).

     (b) All computations of interest and fees hereunder shall be made on the
basis of year of 360 days for the actual number of days including the first day
but excluding the last day) occurring in the period for which such interest is
payable.

                               OPINION OF COUNSEL



                                                                          [Date]


To the Bank party to the
Credit Agreement referred to below

Ladies and Gentlemen:

                We have acted as counsel for [Name of Borrowers}, each a
corporation or trust organized and existing under the laws of
_____________________ (each a "Borrower" and collectively the "Borrowers"), in
connection with the execution and delivery of the following documents
(collectively, the "Credit Documents"):

                (a) the Credit Agreement, dated as of May 22, 1996 among the
Borrowers and Deutsche Bank AG, New York Branch, (the "Agreement"); and

                (b) the Notes of each Borrower, dated the date hereof and
delivered pursuant to the Agreement;

                This opinion is delivered to you pursuant to Section 3.03 of the
Agreement. Terms used herein which are defined in the Agreement shall have the
respective meanings set forth in the Agreement, unless otherwise defined herein.

                In connection with this opinion, we have examined the originals,
or certified, conformed or reproduction copies of all records, agreements,
instruments and documents as we have deemed relevant or necessary as the basis
for the opinions hereinafter expressed. In stating our opinion, we have assumed
the genuineness of all signatures on original or certified copies, the
authenticity of documents submitted to us as originals and the conformity to
original or certified copies of all copies submitted to us as certified or
reproduction copies.

                We have also assumed, for purposes of the opinions expressed
herein, that the parties to the Credit Documents other than the Borrowers have
the corporate power and authority to enter into and perform each of the Credit
Documents and that each of the Credit Documents has been duly authorized,
executed and delivered by each such other party.

                Based upon the foregoing, and subject to the qualifications set
forth herein, we are of the opinion that:

                1. Each Borrower (i) is a duly organized and validly existing
trust or corporation in good standing under the laws of the jurisdiction of its
incorporation, (ii) has the power and authority to own its property and assets
and to transact the business in which it is engaged and (iii) is duly qualified
as a foreign corporation and in good standing in each jurisdiction where the
ownership, leasing or operation of property or the conduct of its business
requires such qualification.

                2. Each Borrower has the corporate or trust power to execute,
deliver and perform the terms and provisions of each of the Credit Documents to
which it is party and has taken all necessary corporate action to authorize the
execution, delivery and performance by it of each of such Credit Documents. Each
Borrower has duly execute and delivered each of the Credit Documents to which it
is party, and each of such Credit Documents constitutes its legal, valid and
binding obligation enforceable in accordance with its terms except as the
enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization or other similar laws affecting creditors' rights generally and
by general equitable principles (regardless of whether the issue of
enforceability is considered in a proceeding in equity or at law).

Federal Reserve System) or, to the best of our knowledge after due inquiry, any
order, writ, injunction or decree of any court or governmental instrumentality,

agreement or any other agreement, contract or instrument of which we are aware

assets is bound or to which it may be subject or (iii) will violate any

otherwise) or prospects or any Borrower.

                  12. In order to induce the Bank to enter into this Second

                          INVESTMENT ADVISORY AGREEMENT

        Investment Advisory Agreement executed as of February 14, 1996, between
SIERRA PRIME INCOME FUND, a Massachusetts business trust (the "Trust") and
SIERRA INVESTMENT ADVISORS CORPORATION, a California corporation (the
"Advisor").

        Witnesseth:

        That in consideration of the mutual covenants herein contained, it is
agreed as follows:

        1SERVICES TO BE RENDERED BY ADVISOR TO THE TRUST.

        (a) Subject always to the control of the Board of Trustees, the Advisor
will, at its expense, furnish continuously an investment program for the Trust,
will make investment decisions on behalf of the Trust and will, subject to the
provisions of paragraph (c), place all orders for the purchase and sale of its
portfolio securities. Subject always to the control of the Trustees, the Advisor
will also manage, supervise and conduct the other affairs and business of the
Trust and matters incidental thereto. In the performance of its duties, the
Advisor will comply with the provisions of the Agreement and Declaration of
Trust, the By-laws of the Trust and the Trust's stated investment objectives,
policies and restrictions as set forth in its Registration Statement on Form
N-2, File No. 33- 98824 and will use its best efforts to safeguard and promote
the welfare of the Trust and to comply with other policies which the Trustees
may from time to time determine.

        (b) The Advisor, at its expense, will furnish all necessary office space
and equipment, bookkeeping and clerical services (excluding securities
accounting and transfer agency services) required for it to perform its duties
hereunder and will pay all salaries, fees and expenses of Officers and Trustees
of the Trust who are affiliated with the Advisor.

        (c) In the selection of banks, syndicated loan agents, brokers, dealers,
futures commissions merchants or any other sources of portfolio investments for
the Trust (hereafter, "brokers or dealers") and the placing of orders for the
purchaser and/or sale of portfolio investments for the Trust, the Advisor shall
seek to obtain the most favorable price and execution available, except to the
extent it may be permitted to pay higher brokerage commissions for brokerage and
research services as described below. In using its best efforts to obtain for
the Trust the most favorable price and execution available, the Advisor, bearing
in mind the Trust's best interests at all times, shall consider all factors it
deems relevant, including, by way of illustration, price, the size of the
transaction, the nature of the market for the security, the amount of the
commission, the timing of the transaction taking into account market prices and
trends, the reputation, experience and financial stability of the broker or
dealer involved and the quality of service rendered by the broker or dealer in
other transactions. Subject to such policies as the Trustees may determine, the
Advisor shall not be deemed to have acted unlawfully or to have breached any
duty created by this Contract or otherwise solely by reason of its having caused
the Trust to pay, a broker or dealer that provides brokerage and research
services to the Advisor an amount of commission for effecting a portfolio
investment transaction in excess of the amount of commission another broker or
dealer would have charged for effecting that transaction, if the Advisor
determines in good faith that such amount of commission was reasonable in
relation to the value of the brokerage and research services provided by such
broker or dealer, viewed in terms of either that particular transaction or the
Advisor's overall responsibilities with respect to the Trust and to other
clients of the Advisor as to which the Advisor exercised investment discretion.
The Trust hereby agrees with the Advisor and with any Sub-Advisor selected by
the Advisor as provided in Section 1(d) that any entity or person associated
with the Advisor or such Sub-Advisor which is a member of a national securities
exchange is authorized to effect any transaction on such exchange for the
account of the Trust which is permitted by Section 11(a)(1)(H) of the Securities

                                      -45-

<PAGE>   2
Exchange Act of 1934 and Rule 11a2-2(T) thereunder, and the Trust hereby
consents to the retention of compensation for such transactions in accordance
with Rule 11a2-2(T)(a)(2)(iv).

        (d) Subject to the provisions of the Agreement and Declaration of Trust
of the Trust and the Investment Company Act of 1940, the Advisor, at its
expense, may select and contract with one or more investment advisers (the
"Sub-Adviser") for the Trust to perform some or all of the services for which it
is responsible pursuant to paragraph (a) of this Section 1 (and any related
facilities or services for which it is responsible under paragraph (b) of this
Section 1). The Advisor will compensate any Sub-Adviser of the Trust for its
services to the Trust. The Advisor may terminate the services of any Sub-Adviser
at any time in its sole discretion, and shall at such time assume the
responsibilities of such Sub-Advisor unless and until a successor Sub-Adviser is
selected.

        (e) The Advisor shall not be obligated to pay any expenses of or for the
Trust not expressly assumed by the Advisor pursuant to this Section other than
as provided in Section 3.

        2.  OTHER AGREEMENTS, ETC.

        It is understood that any of the shareholders, Trustees officers and
employees of the Trust may be a shareholder, director, officer or employee of,
or be otherwise interested in, the Advisor, and in any person controlled by or
under common control with the Advisor, and that the Advisor and any person
controlled by or under common control with the Advisor may have an interest in
the Trust.

        The Trust also understands that the Advisor now acts, will continue to
act and may act in the future as investment adviser to fiduciary and other
managed accounts and as investment adviser to one or more other investment
companies or series of investment companies, and the Trust has no objection to
the Advisor so acting, provided that whenever the Trust and one or more other
accounts or investment companies advised by the Advisor have available funds for
investment, investments suitable and appropriate for each will be allocated in
accordance with procedures believed to be equitable to each entity. Similarly,
opportunities to sell securities will be allocated in an equitable manner. The
Trust recognizes that in some cases this procedure may adversely affect the size
of the position that may be acquired or disposed of for the Trust. In addition,
the Trust understands that the persons employed by the Advisor to assist the
performance of the Advisor's duties hereunder will not devote their full time to
such services and nothing contained herein shall be deemed to limit or restrict
the right of the Advisor or any affiliate of the Advisor to engage in and devote
time and attention to other businesses or to render services of whatever kind or
nature.

        3.  COMPENSATION TO BE PAID BY THE TRUST TO THE ADVISOR.

        The Trust will pay to the Advisor as compensation for services rendered,
for the facilities furnished and for the expenses borne by the Advisor pursuant
to Section 1, a fee, computed and paid monthly at the annual rate of .95% of the
value of the Trust's average daily net assets. Such average daily net asset
value of the Trust shall be determined by taking an average of all of the
determinations of such net asset value during such month at the close of
business on each business day during such month while this Agreement is in
effect. Such fee shall be payable for each month within five (5) business days
after the end of such month.

        In the event that expenses of the Trust for any fiscal year (not
including any interest, taxes, brokerage, extraordinary expenses or distribution
expenses paid by the Trust pursuant to any distribution plan) should exceed the
expense limitation on investment company expenses enforced by any statute or
regulatory authority of any jurisdiction in which shares of the Trust are
qualified for offer and sale, the compensation due the Advisor for such fiscal
year shall be reduced by the amount of such excess by a reduction or refund
thereof. In the event that the expenses of the Trust exceed any expense
limitation which the Advisor may, by written notice to the Trust, voluntarily
declare to be effective with respect to the Trust, subject to such terms and
conditions as the Advisor may prescribe in such notice, the compensation due the
Advisor shall be reduced, and, if necessary, the Advisor shall bear the Trust's
expenses to the extent required by such expense limitation.


                                      -46-

<PAGE>   3
        The Advisor shall not be required to reimburse any amount in excess of
the compensation paid to it pursuant to Section 3. If the Advisor shall serve
for less than the whole of a month, the foregoing compensation shall be
prorated.

        4.  ASSIGNMENT TERMINATES THIS AGREEMENT; AMENDMENTS OF THIS
            AGREEMENT.

        This Agreement shall automatically terminate, without the payment of any
penalty, in the event of its assignment; and this Agreement shall not be amended

majority of the outstanding shares of the Trust, and by the vote, cast in person
at a meeting called for the purpose of voting on such approval, of a majority of
the Board of Trustees who are not interested persons of the Trust or of the
Advisor or of any Sub-Adviser of the Trust as defined in the Investment Company
Act of 1940, as amended .

        5EFFECTIVE PERIOD AND TERMINATION OF THIS AGREEMENT.

        This Agreement shall become effective upon its execution, and shall
remain in full force and effect continuously thereafter (unless terminated

         Agreement by not more than sixty days' written notice delivered or
         mailed by registered mail, postage prepaid, to the other party, or

                         (b) If (i) the Board of Trustees or the shareholders by
         the affirmative vote of a majority of the outstanding shares of the
         Trust, and (ii) a majority of the Board of Trustees who are not
         interested persons of the Trust or of the Advisor, as defined in the

         meeting called for the purpose of voting on such approval, do not
         specifically approve at least annually the continuance of this
         Agreement, then this Agreement shall automatically terminate at the
         close of business on the second anniversary of its execution, or upon
         the expiration of one year from the effective date of the last such
         continuance, whichever is later; provided, however, that if the
         continuance of this Agreement is submitted to the shareholders of the
         Trust for their approval and such shareholders fail to approve such
         continuance of this Agreement as provided herein, the Advisor may
         continue to serve hereunder in a manner consistent with the Investment
         Company Act of 1940 and the rules and regulations thereunder.

        Action by the Trust under paragraph (a) above may be taken either (i) by
vote of a majority of its Trustees, or (ii) by the affirmative vote of a
majority of the outstanding shares of the Trust.

        Termination of this Agreement pursuant to this Section 5 shall be
without the payment of any penalty.

        1.  CERTAIN INFORMATION.

        The Advisor shall promptly notify the Trust in writing of the occurrence
of any of the following events: (a) the Advisor shall fail to be registered as
an investment adviser under the Investment Company Act of 1940, as amended, from
time to time, and under the laws of any jurisdiction in which the Advisor is
required to be registered as an investment adviser in order to perform its
obligations under this Agreement, (b) the Advisor shall have been served or
otherwise have notice of any action, suit, proceeding, inquiry or investigation,
at law or in equity, before or by any court, public board or body, involving the
affairs of the Trust and (c) there shall be any change in the control of the
Advisor.

        2.  CERTAIN DEFINITIONS.

        For the purposes of this Agreement, the "affirmative vote of a majority
of the outstanding shares" of the Trust means the affirmative vote, at a duly
called and held meeting of shareholders, (a) of the holders of 67% or more

                                      -47-

<PAGE>   4
of the shares of the Trust present (in person or by proxy) and entitled to vote
at such meeting, if the holders of more than 50% of the outstanding shares of
the Trust entitled to vote at such meeting are present in person or by proxy, or
(b) of the holders of more than 50% of the outstanding shares of the Trust
entitled to vote at such meeting, whichever is less.

        For the purposes of this Agreement, the terms "affiliated person",

"specifically approve at least annually" shall be construed in a manner
consistent with the Investment Company Act of 1940 and the rules and regulations
thereunder; and the term "brokerage and research services" shall have the
meaning given in the Securities Exchange Act of 1934, as amended, and the rules
and regulations thereunder.

        3.  NONLIABILITY OF ADVISOR.

        The Advisor shall exercise its best judgement in rendering its services
under this Agreement. In the absence of willful misfeasance, bad faith or gross
negligence on the part of the Advisor, or reckless disregard of its obligations
and duties hereunder, the Advisor shall not be subject to any liability to the
Trust, or to any shareholder of the Trust, for any act or omission in the course
of, or connected with, rendering services hereunder.

        4.  USE OF NAME.

        The Advisor owns the name "Sierra", which may be used by the Trust only
with the consent of the Advisor. The Advisor consents to the use by the Trust of
the name "Sierra Prime Income Fund" or any other name embodying the name
"Sierra", but only on condition and so long as (i) this Agreement shall remain
in full force, (ii) the Trust shall fully perform, fulfill and comply with all
provisions of this Agreement expressed herein to be performed, fulfilled or
complied with by it, and (iii) Sierra Investment Advisors Corporation is the
Advisor of the Trust. No such name shall be used by the Trust at any time or in
any place or for any purposes or under any conditions except as provided in this
section. The foregoing authorization by the Advisor to the Trust to use the name
"Sierra" as part of a business or name is not exclusive of the right of the
Advisor itself to use, or to authorize others to use, the same; the Trust
acknowledges and agrees that as between the Advisor and the Trust, the Advisor
has the exclusive right so to use, or authorize others to use, said name, and
the Trust agrees to take such action as may reasonably be requested by the
Advisor to give full effect to the provisions of this section (including,
without limitation, consenting to such use of said name). Without limiting the
generality of the foregoing, the Trust agrees that, upon (i) any termination of
this Agreement by either party, (ii) the violation of any of its provisions by
the Trust or (iii) termination of this Investment Advisor Agreement between the
Advisor and the Trust, the Trust will, at the request of the Advisor, within six
months after such termination or violation, use its best efforts to change the
name of the Trust so as to eliminate all reference, if any, to the name "Sierra"
and will not thereafter transact any business in a name containing the name
"Sierra" in any form or combination whatsoever, or designate itself as the same
entity as or successor to an entity of such name, or otherwise use the name
"Sierra" or any other reference to the Advisor. Such covenants on the part of
the Trust shall be binding upon it, its trustees, offices, stockholders,
creditors and all other persons claiming under or through it.

        5.  LIMITATION OF LIABILITY OF THE TRUSTEES AND SHAREHOLDERS.

        A copy of the Agreement and Declaration of Trust of the Trust is on file
with the Secretary of The Commonwealth of Massachusetts, and notice is hereby
given that this instrument is executed on behalf of the Trustees of the Trust,
as Trustees, and not individually and that the obligations of this instrument
are not binding upon any of the Trustee or shareholders individually but are
binding only upon the assets and property of the Trust.

                        INVESTMENT SUB-ADVISORY AGREEMENT

                        Effective as of October 31, 1996


Van Kampen American Capital Management Inc.
One Parkview Plaza
Oakbrook Terrace, Illinois   60181


Dear Sirs:

                  Sierra Prime Income Fund (the "Trust"), an unincorporated
business trust organized under the laws of the Commonwealth of Massachusetts,
and Sierra Investment Advisors Corporation ("Sierra Advisors"), a corporation
organized under the laws of the State of California, hereby agree with Van
Kampen American Management Inc. (the "Sub-advisor"), a corporation organized
under the laws of the State of Delaware, as follows:


                  1.       Investment Description; Appointment

                  The Trust desires to employ the capital of the Trust by
investing and reinvesting in investments of the kind and in accordance with the
limitations specified in its Agreement and Declaration of Trust, as amended
("Declaration of Trust"), and in its Prospectus and Statement of Additional
Information relating to the Trust as in effect and which may be amended from
time to time, and in such manner and to such extent as may from time to time be
approved by the Board of Trustees of the Trust. Copies of the Trust's Prospectus
and Statement of Additional Information and the Trust's Declaration of Trust, as
amended or restated, have been or will be submitted to the Subadvisor. The Trust
agrees to provide copies of all amendments to or restatements of the Trust's
Prospectus and Statement of Additional Information and the Trust's Declaration
of Trust to the Sub-advisor on a timely and on-going basis but in all events
prior to such time as said amendments or restatements become effective. The
Sub-advisor will be entitled to rely on all such documents furnished to it by
the Trust or Sierra Advisors. The Trust desires to employ and hereby appoints
the Sub-advisor to act as investment sub-advisor to the Trust. The Sub-advisor
accepts the appointment and agrees to furnish the services described herein for
the compensation set forth below.


                  2.       Services as Investment Sub-advisor

                  Subject to the supervision of the Board of Trustees of the
Trust and of Sierra Advisors, the Trust's investment advisor, the Sub-advisor
will (a) act in conformity with the Trust's Declaration of Trust, the Investment
Company Act of 1940, the Investment Advisers Act of 1940 and the Internal
Revenue Code of 1986, as the same may from time to time be amended, (b) make
investment decisions for the Trust in accordance with the Trust's investment
objectives and policies as stated in the Trust's Prospectus(es) and Statement of
Additional Information as in effect and, after timely notice to the Sub-advisor,
which may be amended from time to time, (c) place purchase and sale orders on
behalf of the Trust to effectuate the investment decisions made, (d) maintain
books and records with respect to the securities transactions of the Trust and
will furnish the Trust's Board of Trustees such periodic, regular and special
reports as the Board may reasonably request; and (e) treat confidentially and as
proprietary information of the Trust, all records and other information
specifically relative to the Trust and prior, present or potential shareholders;
and will not use such records and information for any purpose other than
performance of its responsibilities and duties hereunder, except after prior
notification to and approval in writing by the Trust, which approval shall not
be unreasonably withheld or delayed and such records may not be withheld where
the Sub-advisor is subject to audit by the U.S. Securities and Exchange
Commission or other regulatory, administrative or judicial proceeding or audit
or where the Sub-advisor may be exposed to civil or criminal contempt
proceedings for failure to comply, when requested to divulge such information


<PAGE>   2
by duly constituted authorities, or when so requested by the Trust. In providing
those services, the Sub-advisor will supervise the Trust's investments and
conduct a continual program of investment, evaluation and, if appropriate, sale
and reinvestment of the Trust's assets. In addition, the Sub-advisor will
furnish the Trust or Sierra Advisors with whatever statistical information the
Trust or Sierra Advisors may reasonably request with respect to the instruments
that the Trust may hold or contemplate purchasing.


                  3.       Brokerage

                  In executing transactions for the Trust and selecting banks,
syndicated loan agents, brokers or dealers (hereinafter referred to as "brokers
or dealers"), the Sub-advisor will use its best efforts to seek the best overall
terms available and shall execute or direct the execution of all such
transactions in a manner permitted by law and in a manner that is in the best
interest of the Trust and its shareholders. In assessing the best overall terms
available for any Trust transaction, with respect to the lenders from whom the
Trust will purchase assignments and participations in Senior Loans the
Sub-advisor will consider all factors it deems relevant including, but not
limited to their professional ability, level of service, relationship with the
borrower, financial condition, credit standards and quality of management. With
respect to investments other than Senior Loans, the Sub-advisor will consider
all factors it deems relevant including, but not limited to, 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 any
commission for the specific transaction and on a continuing basis. Pursuant to
its investment determinations for the Trust, in placing orders with brokers or
dealers, the Sub-advisor will attempt to obtain the best net price and the most
favorable execution of its orders. Consistent with this obligation, when the
execution and price offered by two or more brokers or dealers are comparable,
the Sub-advisor may, in its discretion, purchase and sell portfolio securities
to and from brokers or dealers who provide the Trust with research advice and
other services.


                  4.       Information Provided to the Trust

                  The Sub-advisor will keep the Trust and Sierra Advisors
informed of developments materially affecting the Trust, and will on its own
initiative, furnish the Trust and Sierra Advisors on at least a quarterly basis
with whatever information the Sub-advisor reasonably believes is appropriate for
this purpose.


                  5.       Standard of Care

                  The Sub-advisor shall exercise its reasonable best judgment in
rendering the services described in Paragraphs 2 and 3 above. The Sub-advisor
shall not be liable for any error of judgment or mistake of law or for any loss
suffered by the Trust or the Advisor in connection with the matters to which
this Agreement relates, except (a) a loss resulting from a breach of fiduciary
duty with respect to the receipt of compensation for services (in which case any
award of damages shall be limited to the period and the amount set forth in
Section 36(b)(3) of the Investment Company Act of 1940, as amended) or (b) a
loss resulting from willful misfeasance, bad faith or gross negligence on its
part in the performance of its duties or from reckless disregard by it of its
obligations and duties under this Agreement (each such breach, act or omission
described in (a) or (b) shall be referred to as "Disqualifying Conduct").


                  6.       Compensation

                  In consideration of the services rendered pursuant to this
Agreement, Sierra Advisors will pay the Sub-advisor on the first business day of
each month a fee for the previous month at an annual rate of .475% of the
Trust's average daily net assets. The Sub-advisor shall have no right to obtain
compensation directly from the Trust or the Trust for services provided
hereunder and agrees to look solely to Sierra Advisors for payment of fees due.
Upon any termination of this Agreement before the end of a month, the fee for
such part of that month shall be prorated according to the proportion that such
period bears to the full monthly period and shall be payable upon the date of
termination of

                                       -2-

<PAGE>   3
this Agreement. For the purpose of determining fees payable to the Sub-advisor,
the value of the Trust's net assets shall be computed at the times and in the
manner specified in the Trust's Prospectus and/or Statement of Additional
Information relating to the Trust as from time to time in effect.

                  Should it be determined that the Investment Sub-Advisory
Agreement between the Trust, Sierra Advisors and Sub-Advisor dated February 14,
1996, is terminated as a result of the assignment thereof prior to the effective
date of this Agreement, compensation thereunder shall commence as of the date of
such termination.


                  7.       Expenses

                  The Sub-advisor will bear all expenses in connection with the
performance of its services under this Agreement, which expenses shall not
include brokerage fees or commissions in connection with the effectuation of
securities transactions. The Trust (or Sierra Advisors) will bear certain other
expenses to be incurred in its operation, including but not limited to:
organizational expenses, taxes, interest, brokerage fees and commissions, if
any; fees of Trustees of the Trust who are not officers, directors or employees
of the Sub-advisor, Sierra Advisors, the Trust's subadministrator or any of
their affiliates; Securities and Exchange Commission fees and state Blue Sky
qualification fees; out-of-pocket expenses of custodians, transfer and dividend
disbursing agents and the Trust's sub-administrator and transaction charges of
custodians; insurance premiums; outside auditing and legal expenses; costs of
maintenance of the Trust's existence; costs attributable to investor services,
including without limitation, telephone and personnel expenses; costs of
preparing and printing prospectuses and statements of additional information for
regulatory purposes and for distribution to existing shareholders; costs of
shareholders' reports and meetings of the shareholders of the Trust and of the
officers or Board of Trustees of the Trust; and any extraordinary expenses.


                  8.       Services to Other Companies or Accounts

                  The Trust understands that the Sub-advisor now acts, will
continue to act and may act in the future as investment adviser to fiduciary and
other managed accounts and as investment advisor or sub-investment advisor to
one or more other investment companies or series of investment companies, and
the Trust has no objection to the Subadvisor so acting, provided that whenever
the Trust and one or more other accounts or investment companies advised by the
Sub-advisor have available funds for investment, investments suitable and
appropriate for each will be allocated in accordance with procedures believed to
be equitable to each entity. Similarly, opportunities to sell securities will be
allocated in an equitable manner. The Trust recognizes that in some cases this
procedure may limit the size of the position that may be acquired or disposed of
for the Trust. In addition, the Trust understands that the persons employed by
the Sub-advisor to assist in the performance of the Sub-advisor's duties
hereunder will not devote their full time to such service and nothing contained
herein shall be deemed to limit or restrict the right of the Sub-advisor or any

                             DISTRIBUTION AGREEMENT


Sierra Investment Services Corporation
9301 Corbin Avenue, Suite 333
Northridge, California  91324


Ladies and Gentlemen:

         This is to confirm that, whereas the undersigned Sierra Prime Income
Fund (the "Trust"), a business trust organized under the laws of the
Commonwealth of Massachusetts and registered as a closed-end, management
investment company under the Investment Company Act of 1940, as amended (the
"1940 Act"), and Sierra Investment Services Corporation ("Sierra Services"), a
corporation organized under the laws of the State of California, have entered
into a Distribution Agreement dated as of February 14, 1996 pursuant to which
the Trust and Sierra Services have agreed that Sierra Services shall act as a
distributor of the classes of Common Shares of beneficial interest of the Trust.

         Now, therefore, in consideration of the mutual promises and covenants
hereinafter contained, the Trust and Sierra Services do agree as follows:


1.       Appointment

         The Trust hereby appoints Sierra Services as agent of the Trust to act,
for the period and on the terms set forth in this Agreement, as a distributor of
the Trust Shares covered by the Trust's registration statement (the
"Registration Statement"), prospectuses and statements of additional information
as in effect from time to time under the Securities Act of 1933, as amended (the
"1933 Act"), and the 1940 Act, and Sierra Services accepts such appointment and
agrees to render the services herein described for the compensation herein
provided.

         As used in this Agreement, the terms "registration statement,"
"prospectus," and "statement of additional information" shall mean any
registration statement, prospectus and statement of additional information filed
by the Trust with the Securities and Exchange Commission ("SEC" or "Commission")
and any amendments thereof and supplements thereto which at any time shall have
been filed with the SEC. "Prospectus" shall mean, with respect to any Shares of
the Trust at any time, the then-current prospectus and statement of additional
information relating to such Shares. The Trust and Sierra Services acknowledge
expressly that references in this Agreement to the "term" or "period" of this
Agreement shall include the term or period of this Original Agreement.

2.       Sales of Shares

         A. Authorization. The Trust hereby authorizes Sierra Services to sell
Shares of the Trust, and Sierra Services agrees to use its best efforts to
solicit orders for the sale of such Shares, at such Shares' public offering
price, as determined in accordance with the Registration Statement. Sierra
Services shall have the right to order from the Trust the Shares of the Funds
needed, but not more than needed (correcting for any clerical errors or errors
of transmission), to fill such orders as are unconditional.

         B. Selling Broker-Dealers and Other Agents. Sierra Services may, as
principal and on its own behalf, enter into agreements ("Dealer Agreements"), on
such terms and conditions as Sierra Services determines are not inconsistent
with this Agreement, with (a) any broker-dealer who is (i) registered under the
Securities Exchange Act of 1934, as amended (the "1934 Act"), (ii) registered as
required under applicable state securities or blue sky laws,


<PAGE>   2
and (iii) a member in good standing of the National Association of Securities
Dealers, Inc. ("NASD"); and (b) any other person (as such term is defined in the
1934 Act) that is not required, for purposes of effecting transactions in
securities, to be registered under the 1934 Act, but is registered as required
under applicable state securities or blue sky laws, authorizing such
broker-dealers and other persons (collectively, "Brokers") to act as agents in
connection with the sale of the Shares of the Trust (which may include accepting
orders for the purchase or redemption of Shares, responding to inquiries
regarding the Trust or the Funds, and performing other related functions).
Expulsion or suspension from the NASD of any Broker required to be registered
under the 1934 Act shall automatically terminate such Broker's Dealer Agreement
with Sierra Services for sales of Shares as of the effective date of such
expulsion or suspension.

         C. Refusal and Suspension of Sales. Each of Sierra Services and the
Trust reserves the right to refuse at any time or times (a) to sell any Shares
for any reason, and (b) to accept an order for Shares for any reason. Sierra
Services acknowledges specifically that, whenever in the judgment of the Trust's
officers such action is warranted for any reason, including, without limitation,
market, economic or political conditions, the Trust may decline to accept any
orders for, or make any sales of, any Shares until such time as those officers
deem it advisable to accept such orders and to make such sales.

         No Shares shall be offered and no orders for the purchase or sale of
Shares under any provisions of this Agreement shall be accepted by the Trust (a)
if and so long as the effectiveness of the Registration Statement or any
necessary amendments thereto shall be suspended under any provisions of the 1933
Act, or (b) if and so long as a current prospectus as required by Section
5(b)(2) of the 1933 Act is not on file with the SEC.

3.       Distribution Services and Expenses

         A. Distribution Expenses. Sierra Services will bear all expenses in
connection with the performance of its services and the incurring of
distribution expenses under this Agreement. For purposes of this Agreement,
"distribution expenses" of Sierra Services shall mean all expenses borne by
Sierra Services or by any other person with which Sierra Services has an
agreement (including but not limited to Dealer Agreements) approved by the
Trust, which expenses represent payment for activities primarily intended to
result in the sale of Shares, including, but not limited to, the following

connection with services that Sierra Services or any other person have agreed to
bear or provide without reimbursement or compensation):

                  representatives and other employees of Sierra Services or of 
                  Brokers;

                  (2) payments made to, and expenses of, persons providing
                  support services in connection with the distribution of

                  equipment, telephone facilities, answering routine inquiries
                  regarding the Trust, and processing transactions;

                  (3) costs relating to the formulation and implementation of
                  marketing and promotional activities, including but not
                  limited to direct mail promotions and television, radio,
                  newspaper, magazine and other mass media advertising, and
                  costs involved in preparing, printing and distributing
                  advertising and sales literature pertaining to the Trust;

                  (4) costs of printing and distributing Prospectuses and

                  and reports with respect to marketing and promotional
                  activities that the Trust may, from time to time, deem
                  advisable; and

                  (6) costs of financing any of the foregoing.

4.       Compensation

         The Distributor will receive no compensation from the Trust in
consideration of its services in connection with the distribution of Shares of
the Trust.

         A. Early Withdrawal Charges. The Trust shall cause its transfer agent

such holders in accordance with the terms of the Prospectuses relating to such
Shares ("EWCs") and shall cause the Transfer Agent to pay such amounts over as
promptly as possible after the settlement date for each repurchase of such
Shares.

         B. Other Services; Service Fee. Upon request of the Trust's Board of
Trustees, Sierra Services may, but shall be under no duty to, perform additional
services on behalf of the Trust, which services are not required by this
Agreement but may be performed by Sierra Services in conformity with applicable
law. Any such services will be performed on behalf of the Trust, and Sierra
Services may impose additional charges for such services, which charges may be
billed to the Trust and subject to examination by the Trust's independent
accountants. Sierra Services's payment or assumption of any expense of the Trust
that Sierra Services is not required to pay or assume under this Agreement shall
not relieve Sierra Services of any of its obligations to the Trust or obligate
Sierra Services to pay or assume any similar expense on any subsequent occasion.

         Any shareholder services provided by Sierra Services to the Trust,
which services may include processing of shareholder transactions, responding to
inquiries from shareholders concerning the status of their accounts and the
operations of the Trust communicating with the Trust and its transfer agent on
behalf of such shareholders, or providing other shareholder services, nor for
any expenses associated with the provision of such shareholder services,
including office space and equipment, and telephone facilities, shall be
provided pursuant to a separate agreement.

         C. Directed Payment; Allocable Portion Calculations. Sierra Services
may direct the Trust to pay any part or all of the EWCs payable to Sierra
Services in respect of any Shares directly to persons providing funds to Sierra
Services to cover or otherwise enable the incurring of expenses associated with
distribution services, and the Trust agrees to accept and to comply with such
direction. Sierra Services shall, at its own expense and not the expense of the
Trust, provide the Trust with any necessary calculations of Sierra Services's
Allocable Portion of any EWCs, and the Trust shall be entitled to rely
conclusively on such calculations, without prejudice to any claim it may have
concerning the accuracy of such calculations.

         D. Maximum Charges. Notwithstanding anything to the contrary contained
in this Agreement, EWCs paid to Sierra Services by any class of shares of the
Trust shall not exceed the amount permitted by the Rules of Fair Practice of the
NASD ("NASD Rules"), as in effect from time to time, and the aggregate amount of
EWCs paid to Sierra Services by any class of shares of the Trust shall not
exceed 8.50% of the offering price (determined in accordance with the NASD Rules
in effect from time to time).

of Shares, any Prospectus furnished by the Trust from time to time. Sierra
Services shall not, and shall take reasonable steps to ensure that no Broker
will, give any information nor make any representations, concerning any aspect
of the Shares or the Trust to any persons or entity unless such information or
representations are contained in the Registration Statement and/or the pertinent
Prospectus, or are contained in sales or promotional literature approved by the
Trust. Sierra Services shall not use, and shall take reasonable steps to ensure
that no Broker will, use any sales promotion material or advertising that has

         A. Compliance. In performing any activity as distributor for the Shares
pursuant to this Agreement, Sierra Services shall comply with:

                  (1) all applicable provisions of the 1940 Act and any rules
                  and regulations thereunder;

                  (2) all provisions of the Registration Statement relating to
                  the Trust;

registered representatives or other associated persons, under the 1934 Act and
applicable state securities or blue sky laws. Sierra Services shall be
responsible for ensuring that each Broker and its representatives engaged in

and otherwise qualified to do so under the 1934 Act and any applicable blue sky
laws of each state or other jurisdiction in which such Shares may be sold.
Sierra Services shall be responsible for ensuring that each Broker supervises
its representatives. Expulsion or suspension of Sierra Services from the NASD
shall automatically terminate this Agreement on the effective date of such

         B. Direction of the Board. Any distribution activities undertaken by
Sierra Services pursuant to this Agreement or any other services undertaken by
Sierra Services on behalf of the Trust, shall at all times be subject to any
directives of the Board of Trustees of the Trust.

         C. Standard of Care. In performing its duties under this Agreement,
Sierra Services shall be obligated to exercise care and diligence and to act in
good faith and to use its best efforts within reasonable limits in performing
all services provided for under this Agreement, but shall not be liable for any
act or omission not constituting Sierra Services's willful misfeasance, bad
faith or gross negligence, or Sierra Services's reckless disregard of its duties
under this Agreement.

8.       Representations and Warranties

         A. Registration Statements and Prospectuses. The Trust represents to
Sierra Services that all Registration Statements and Prospectuses filed by the
Trust with the SEC under the 1933 Act and the 1940 Act with respect to the
Shares are in conformity with the requirements of the 1933 Act, the 1940 Act and
the rules and regulations of the SEC thereunder. The Trust represents and
warrants to Sierra Services that any Registration Statement or Prospectus, when
it becomes effective, will include all statements required to be contained
therein in conformity with the 1933 Act, the 1940 Act and the rules and
regulations of the SEC; that all statements of fact contained in any
Registration Statement or Prospectus will be true and correct when such
Registration Statement or Prospectus becomes effective; and that no Registration
Statement nor any Prospectus, when the same shall become

                                       -5-

<PAGE>   6
effective, will include 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 to a purchaser of Shares. Sierra Services may,
but shall not be obligated to, propose from time to time such amendment(s) to
any Registration Statement and such supplement(s) to any Prospectus as, in the
light of future developments, may, in the opinion of Sierra Services or its
counsel, be necessary or advisable. The Trust shall not file any amendment to
any Registration Statement or supplement to any Prospectus without giving Sierra
Services reasonable notice thereof in advance; provided, however, that nothing
contained in this Agreement shall in any way limit the Trust's right to file at
any time such amendment(s) to any Registration Statement and supplement(s) to
any Prospectus, of whatever character, as the Trust may deem advisable, such
right being in all respects absolute and unconditional.

         B. Charter. The Trust represents that a copy of its Agreement and
Declaration of Trust dated October 4, 1995, together with all amendments
thereto, is on file in the office of the Secretary of the Commonwealth of
Massachusetts and the office of the City Clerk of Boston, Massachusetts.

         C. Authorization. Sierra Services represents to the Trust that it is
authorized to perform the services described herein.

         D. NASD. Sierra Services represents to the Trust that it is a member in
good standing of the NASD.

9.       Indemnification

         A. Indemnification by the Trust. The Trust agrees to indemnify, defend
and hold Sierra Services, its officers, directors, agents, employees, and any
person who controls Sierra Services within the meaning of Section 15 of the 1933
Act (Sierra Services and such persons, collectively, "Sierra Services
Indemnified Persons"), free and harmless from and against any and all claims,
demands, liabilities and expenses (including the cost of investigating or
defending such claims, demands or liabilities and any counsel fees incurred in
connection therewith) that any Sierra Services Indemnified Person may incur
under the 1933 Act, the 1940 Act or common law or otherwise, arising out of or
based upon any untrue statement (or alleged untrue statement) of a material fact
contained in any Registration Statement or Prospectus relating to Shares of the
Trust, or arising out of or based upon any omission (or alleged omission) to
state a material fact required to be stated in any Registration Statement or
Prospectus relating to Shares of the Trust, or necessary to make the statements
in such Registration Statement or Prospectus not misleading, or arising out of
or based upon the Trust's material breach of this Agreement; provided, however,
that the Trust's agreement to indemnify Sierra Services Indemnified Persons
shall not be deemed to cover any claims, demands, liabilities or expenses
arising out of or based upon any statements or representations made by Sierra
Services or its representatives or agents other than such statements and
representations as are contained in any Registration Statement or Prospectus and
in such financial and other statements regarding the Shares as are furnished to
Sierra Services pursuant to Sections 5a and 6b of this Agreement; provided
further, that the Trust's agreement to indemnify Sierra Services and the Trust's
representations and warranties hereinbefore set forth in Section 8 of this
Agreement shall not be deemed to cover any liability to the Trust or its
shareholders to which Sierra Services would otherwise be subject by reason of
Sierra Services' willful misfeasance, bad faith or gross negligence in the
performance of its duties, or by reason of Sierra Services' reckless disregard
of its obligations and duties under this Agreement; and provided further, that
this Section 9 shall apply to all acts or omissions by the parties hereto that
occur on or after the date first written above and the indemnification
provisions of this Agreement shall apply to all acts or omissions by the parties
hereto that occur prior to such date.

         The Trust's agreement to indemnify Sierra Services Indemnified Persons
is expressly conditioned upon such Sierra Services Indemnified Person's
notifying the Trust, or causing the Trust to be notified, of any action brought
against such Sierra Services Indemnified Person, such notification to be given
by letter, telegram, telecopy or facsimile addressed to the Trust at its
principal office, within ten (10) days after the summons or other first legal
process shall be served; provided that the failure to provide such notification
within such time limit shall limit the Trust's obligation to indemnify such
persons only to the extent such failure causes prejudice to the interests of the
Trust with respect to such action. The failure so to notify the Trust of any
such action shall not relieve the Trust from any liability that the Trust may
have to the person against whom such action is brought by reason of any such
untrue

                                       -6-

<PAGE>   7
(or alleged untrue) statement or omission (or alleged omission) otherwise than
on account of the Trust's indemnity agreement contained in this Section 9a. The
Trust's indemnification agreement contained in this Section 9a and the Trust's
representations and warranties in this Agreement shall remain operative and in
full force and effect regardless of any investigation made by or on behalf of
any Sierra Services Indemnified Person, and shall survive the delivery of any
Shares and, to the extent permitted by law, the termination of this Agreement.
This agreement of indemnity will inure exclusively to the benefit of Sierra
Services Indemnified Persons and their respective estates or successors, as
applicable.

         B. Indemnification by Sierra Services. Sierra Services agrees to
indemnify, defend and hold the Trust, its officers, directors, agents,
employees, and any person who controls the Trust within the meaning of Section
15 of the 1933 Act (the Trust and such persons, collectively, "Trust Indemnified
Persons"), free and harmless from and against any and all claims, demands,
liabilities and expenses (including the costs of investigating or defending such
claims, demands or liabilities and any counsel fees incurred in connection
therewith) that any Trust Indemnified Person may incur under the 1933 Act, the
1940 Act or common law or otherwise, but only to the extent that such liability
or expense incurred by such Trust Indemnified Person shall arise out of or be
based upon (a) any unauthorized sales literature, advertisements, information,
statements or representations or (b) any untrue statement (or alleged untrue
statement) of a material fact contained in information furnished in writing by
Sierra Services to the Trust and used in the answers to any of the items of the
Registration Statement or in the corresponding statements made in any
Prospectus, or shall arise out of or be based upon any omission (or alleged
omission) to state a material fact in connection with such information furnished
in writing by Sierra Services to the Trust and required to be stated in such
answers or necessary to make such information not misleading, or shall arise out
of or be based upon Sierra Services' material breach of this Agreement;
provided, that this Section 9 shall apply to all acts or omissions by the
parties hereto that occur on or after the date first written above and the
indemnification provisions of the Original Agreement shall apply to all acts or
omissions by the parties hereto that occur prior to such date.

         Sierra Services' agreement to indemnify Trust Indemnified Persons is
expressly conditioned upon such Trust Indemnified Person's notifying Sierra
Services, or causing Sierra Services to be notified, of any action brought
against such Trust Indemnified Person, such notification to be given by letter,
telegram, telecopy or facsimile addressed to Sierra Services at its principal
office, within ten (10) days after the summons or other first legal process
shall be served; provided that the failure to provide such notification within
such time limit shall limit Sierra Services' obligation to indemnify such
persons only to the extent such failure causes prejudice to the interests of
Sierra Services with respect to such action. The failure so to notify Sierra
Services of any such action shall not relieve Sierra Services from any liability
that Sierra Services may have to the Trust Indemnified Person by reason of any
such untrue (or alleged untrue) statement or omission (or alleged omission)
otherwise than on account of Sierra Services' indemnity agreement contained in
this Section 9b. Sierra Services' indemnification agreement contained in this
Section 9b and its representations and warranties in this Agreement shall remain
operative and in full force and effect regardless of any investigation made by
or on behalf of any Trust Indemnified Person, and shall survive the delivery of
any Shares and, to the extent permitted by law, the termination of this
Agreement. This agreement of indemnity will inure exclusively to the benefit of
Trust Indemnified Persons and their respective estates or successors, as
applicable.

         C. Assumption of Defense. An indemnifying party will be entitled to
assume the defense of any suit brought to enforce any such claim, demand or
liability, but, in such case, such defense shall be conducted by counsel of good
standing chosen by the indemnifying party and approved by the indemnified party
(provided that such counsel shall not, except with the consent of an indemnified
party that is a Sierra Services Indemnified Person, be counsel to any investment
fund of the Trust); provided that the indemnified party shall be entitled to
conduct its own defense with counsel selected by it if such indemnified party is
advised by counsel that there may be a conflict of interest between the
indemnified party and the indemnifying party with respect to such defense. In
the event the indemnifying party elects to assume the defense of any such suit
and retain counsel of good standing approved by the indemnified party, the
defendant or defendants in such suit shall bear the fees and expenses of any
additional counsel retained by any of them; but in case the indemnifying party
does not elect or is not permitted to assume the defense of any such suit, or in
case the indemnified party does not approve of counsel chosen by the
indemnifying party, the indemnifying

                                       -7-

<PAGE>   8
party will reimburse the indemnified party named as defendant or defendants in
such suit, for the fees and expenses of any counsel retained by such indemnified
party.

         D. Notice. Each of Sierra Services and the Trust agrees to notify the
other promptly of the commencement of any litigation or proceedings against it
or any of its officers or directors or Trustees, as applicable, in connection
with the issuance and sale of any Shares.

         E. Contribution. If the indemnification provided for in this Section
shall for any reason be unavailable to or insufficient to hold harmless a party
indemnified hereunder in respect of any claim, demand, liability or expense, or
any action in respect thereof, referred to therein, then each indemnifying party
shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such claim, demand,
liability or expense, or action in respect thereof, (a) in such proportion as
shall be appropriate to reflect the relative benefits received by the Trust on
the one hand and Sierra Services on the other from the offering of the Shares or
(b) if the allocation provided by clause (a) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (a) above but also the relative fault of
the Trust (and its agents other than Sierra Services) on the one hand and Sierra
Services on the other with respect to the statements or omissions which resulted
in such claim, demand, liability or expense, or action in respect thereof, as
well as any other relevant equitable considerations. The relative benefits
received by the Trust on the one hand and Sierra Services on the other with
respect to the offering of the Shares shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Shares purchased
under this agreement (before deducting expenses) received by the Trust bear to
the total net underwriting discounts and commissions received by Sierra Services
with respect to the Shares purchased under this Agreement and retained by Sierra
Services after payments to the selling agents retained by it. The relative fault
shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Trust (or any of its agents other
than Sierra Services) or by Sierra Services, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Trust and Sierra Services agree that it would
not be just and equitable if contributions pursuant to this Section were to be
determined by pro rata allocation or by any other method of allocation which
does not take into account the equitable considerations referred to herein. The
amount paid or payable by an indemnified party as a result of the claim, demand,
liability or expense, or action in respect thereof, referred to above in this
Section shall be deemed to include, for purposes of this Section, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section, Sierra Services shall not be required to contribute
any amount in excess of the amount by which the total net underwriting discounts
and commissions received by Sierra Services with respect to the Shares purchased
under this Agreement and retained by Sierra Services after payments to the
selling agents retained by it exceed the amount of any damages which Sierra
Services has otherwise paid or become liable to pay by reason of any untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.

10.       Notice to Sierra Services.

         A. The Trust agrees to advise Sierra Services immediately in writing:

                  (1) of any request by the SEC for amendments to the
                  Registration Statement or Prospectus then in effect or for 
                  additional information;

                  (2) in the event of the issuance by the SEC of any stop order
                  suspending the effectiveness of the Registration Statement or
                  Prospectus then in effect or the initiation of any proceeding
                  for that purpose;

                  (3) of the happening of any event that makes untrue any
                  statement of a material fact made in the Registration
                  Statement or Prospectus then in effect or that requires the
                  making of a change in

                                       -8-

<PAGE>   9
                  such Registration Statement or Prospectus in order to make the
                  statements therein not misleading; and

                  (4) of all actions of the SEC with respect to any amendment to
                  any Registration Statement or Prospectus that may from time to
                  time be filed with the SEC.

11.      Term of Agreement.

         A. This Agreement shall become effective as of the date first set forth
above, shall remain in effect for an initial period of two years, and shall
continue thereafter from year to year for so long as such continuance is
specifically approved at least annually by

                  (1) the Trust's Board of Trustees or a vote of a "majority of
                  the outstanding voting securities" (as defined in the 1940
                  Act) of the Trust; and

                  (2) a vote of a majority of the Trustees who are not
                  "interested persons" (as defined in the 1940 Act) of the Trust
                  and who have no direct or indirect financial interest in the
                  operation of the Plan, in this Agreement or any other
                  agreement related to the Plan (the "Qualified Trustees"), such
                  vote cast in person at a meeting called for the purpose of the
                  voting on such approval.

12.      Termination.

         A. Termination on Assignment. This Agreement shall terminate
automatically in the event of its "assignment" (as defined in the 1940 Act), it
being understood that this Agreement has been approved by the Trustees,
including the Qualified Trustees. Sierra Services agrees to notify the Trust of
any circumstances that might result in this Agreement being deemed to be
assigned.

         B. Voluntary Termination. The Trust may terminate this Agreement with
respect to the Trust, or in its entirety, without penalty, on 60 days' written
notice to Sierra Services, by vote of a majority of the Qualified Trustees or by
vote of a "majority of the outstanding voting securities" of the Trust, as the
case may be. Sierra Services may terminate this Agreement on 90 days' written
notice to the Trust. Termination of this Agreement with respect to any class of
shares of the Trust shall not cause this Agreement to terminate with respect to
any other class of shares of such Trust. Notice of termination as provided for
in this Section may be waived by either party, such waiver to be in writing.

13.      Miscellaneous.

         A. Non-Exclusivity. The Trust recognizes that Sierra Services and its
affiliates shall be free to render distribution or other services to others
(including other investment companies) and to engage in other activities. The
Trust agrees that the directors, officers and employees of Sierra Services shall
not be prohibited by reason of this Agreement from engaging in any other
business activity or from rendering services to any other person, or from
serving as partners, directors, trustees or officers of any other firm or
corporation, including the Trust and other investment companies. Sierra Services
acknowledges that its appointment as distributor pursuant to this Agreement is
not exclusive, and that the Trust may appoint one or more other persons to act
as distributor for the Shares of one or more Funds.

         B. Independent Contractor. Sierra Services and any Broker shall be
independent contractors and none of them nor any of their directors, officers or
employees shall, as such, be deemed employees of the Trust.

         C. Notices. Any notices under this Agreement shall be in writing,
mailed postage paid or sent by telegram, telecopy, or facsimile to the other
party at such address as such other party may designate from time to time for
the receipt of such notice.

         This Agreement constitutes the entire agreement between the parties
hereto with respect to the subject matter hereof, and may not be modified,
