                      PROSPECTUS -- OCTOBER 23, 1997     
 
  UAM Funds, Inc. (the "Fund") is an open-end, management investment company
known as a "mutual fund." The Fund consists of multiple series (known as
"Portfolios"), each of which has different investment objectives and policies.
The Sirach Bond Portfolio currently offers two separate classes of shares: In-
stitutional Class Shares and Institutional Service Class Shares ("Service
Class Shares"). Shares of each class represent equal, pro rata interests in a
Portfolio and accrue dividends in the same manner except that Service Class
Shares bear fees payable by the class to financial institutions for services
they provide to the owners of such shares. The securities offered in this Pro-
spectus are Institutional Class Shares of one diversified, no-load Portfolio
of the Fund managed by Sirach Capital Management, Inc.
 
  SIRACH BOND PORTFOLIO. The objective of the Sirach Bond Portfolio (the
"Portfolio") is to achieve above-average total return consistent with reason-
able risk to principal by investing primarily in dollar-denominated, invest-
ment grade fixed income securities.
 
  There can be no assurance that the Portfolio will achieve its stated objec-
tive.
   
  Keep this Prospectus for future reference. It contains information that you
should know before you invest. A Statement of Additional Information ("SAI")
containing additional information about the Fund has been filed with the Secu-
rities and Exchange Commission. The SAI is dated October 23, 1997 and has been
incorporated by reference into this Prospectus. For a free copy of the SAI
contact the UAM Funds Service Center at the address or telephone number above.
    
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON
THE ACCURACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

+ The Adviser has voluntarily agreed to waive a portion of its advisory fees
  and to assume expenses otherwise payable by the Portfolio, if necessary, in
  order to reduce its expense ratio. As of the date of this Prospectus, the
  Adviser has agreed to keep the Bond Portfolio Institutional Class Shares
  from exceeding 0.50% of average daily net assets. The Fund will not reim-
  burse the Adviser for any advisory fees that are waived or Portfolio ex-
  penses that the Adviser may bear on behalf of a Portfolio for a given fiscal
  year.
   
  The above table shows various fees and expenses an investor would bear di-
rectly or indirectly. The expenses and fees set forth above are based on esti-
mates. For purposes of calculating the expenses and fees set forth above, the
table assumes that the Bond Portfolio's average daily assets will be $100 mil-
lion. The effect of expense offsets on Total Operating Expenses is excluded.
It is estimated that, without the Adviser's fee waiver, the Investment Advi-
sory Fees would be 0.35% and the Total Operating Expenses would be 0.64% of
the Portfolio's average net assets.

                              PROSPECTUS SUMMARY
 
INVESTMENT ADVISER
   
  Sirach Capital Management, Inc. (the "Adviser"), an investment counseling
firm founded in 1970, serves as investment adviser to six of the Fund's Port-
folios, including the Bond Portfolio. The Adviser presently manages approxi-
mately $7.5 billion in assets for institutional clients and high net worth in-
dividuals. (See "INVESTMENT ADVISER.")     
 
PURCHASE OF SHARES
  Shares of the Portfolio are offered through UAM Fund Distributors, Inc. (the
"Distributor"), to investors at net asset value without a sales commission.
Share purchases may be made by sending investments directly to the Fund. The
minimum initial investment is $2,500. The minimum for subsequent investments
is $100. The minimum initial investment for IRA accounts is $500. Minimum ini-
tial investment for spousal IRA accounts is $250. Certain exceptions to the
initial or minimum investment amounts may be made by the officers of the Fund.
(See "PURCHASE OF SHARES.")
 
DIVIDENDS AND DISTRIBUTIONS
  The Portfolio will normally distribute substantially all of its net invest-
ment income in quarterly dividends. The Portfolio will distribute any realized
net capital gains annually. Distributions will be reinvested in Portfolio
shares automatically unless an investor elects to receive cash distributions.
(See "DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES.")
 
REDEMPTIONS AND EXCHANGES
  Shares of the Portfolio may be redeemed at any time, without cost, at the
net asset value of the Portfolio next determined after receipt of the redemp-
tion request. The redemption price may be more or less than the purchase
price. (See "REDEMPTION OF SHARES.")
 
ADMINISTRATIVE SERVICES
  UAM Fund Services Inc. ("UAMFSI"), a wholly-owned subsidiary of UAM Asset
Management Corporation, is responsible for performing and overseeing adminis-
tration, fund accounting, dividend disbursing and transfer agency services
provided to the Fund and its Portfolios by third-party service providers. (See
"ADMINISTRATIVE SERVICES.")

                                 RISK FACTORS
 
  The value of the Portfolio's shares will fluctuate in response to changes in
market and economic conditions, as well as the financial conditions and pros-
pects of the issuers in which the Portfolio invests. Prospective investors
should consider the following: (1) In general, the Portfolio will not trade
for short-term profits, but when circumstances warrant, investments may be
sold without regard to the length of time held. High rates of portfolio turn-
over may result in additional transaction costs and the realization of capital
gains. (See "PORTFOLIO TURNOVER"); (2) In addition, the Portfolio may use var-
ious investment practices that involve special considerations, including in-
vesting in repurchase agreements, when-issued, forward delivery and delayed
settlement securities and lending of securities. (See "OTHER INVESTMENT POLI-
CIES.")
 
                             INVESTMENT OBJECTIVE
 
  The objective of the Portfolio is to provide above-average total return con-
sistent with reasonable risk to principal by investing primarily in dollar-de-
nominated, investment grade fixed income securities of varying maturities. In-
come return is expected to be a predominant portion of the Portfolio's total
return. Any capital return on the Portfolio is dependent upon interest rate
movements. The capital return from the Portfolio will vary according to, among
other factors, interest rate changes and the average maturity (duration) of
the Portfolio.
 
  There can be no assurance that the Portfolio will achieve its stated objec-
tive.
 
                              INVESTMENT POLICIES
 
  The Portfolio seeks to achieve its objective by investing at least 75% of
its total assets, under normal circumstances, in a diversified mix of dollar-
denominated, investment grade fixed income securities of varying maturities
including securities of the U.S. Government and its agencies, corporate bonds,
mortgage-backed securities including CMOs, asset-backed securities, Yankee
bonds and various short-term instruments. (See "OTHER INVESTMENT POLICIES.")
 
  It is the Adviser's intention that the Portfolio's investments will be lim-
ited to those bonds having one of the four highest grades assigned by Moody's
Investors Services, Inc. ("Moody's") (Aaa, Aa, A or Baa ) or Standard and
Poor's Corporation ("S&P") (AAA, AA, A or BBB). Securities rated Baa by
Moody's or BBB by S&P may have speculative characteristics and could be more
sensitive to changes in the economy and the financial condition of issuers
than higher rated bonds. However, the Adviser reserves the right to retain se-
curities which are downgraded by one or both of the rating agencies if, in its
judgment, retention is warranted. Mortgage-backed securities in which the
Portfolio may invest will either carry a guarantee from an agency of the U.S.
Government or a private issuer of the timely payment of principal and interest
or are suitably structured to be considered
 
                                       4
<PAGE>
 
by the Adviser to be of investment grade quality. The Portfolio's SAI contains
a more detailed description of corporate bond ratings.
 
  Regardless of the rating category, the credit quality of bonds can change
unexpectedly, and even recently-issued credit ratings may not fully reflect
the actual risks posed by a particular security. It is the Portfolio's policy
not to rely primarily on ratings issued by established credit rating agencies,
but to utilize such ratings in conjunction with the Adviser's own independent
and on-going review of credit quality.
 
  The Adviser attempts to be risk averse, believing that preserving principal
in periods of rising interest rates should lead to above-average returns over
the long run. The maturity structure of the Portfolio will be largely deter-
mined by the Adviser's assessment of current economic conditions and trends,
the Federal Reserve Board's management of monetary policy, fiscal policy, in-
flation expectations, government and private credit demands and global condi-
tions. Once these factors have been carefully analyzed, the average
maturity/duration of the Portfolio will be adjusted to reflect the Adviser's
outlook. Under normal market conditions, the weighted average maturity will
range between eight and twelve years, and the weighted average duration will
range between four and six years. Over a complete market cycle, the average
maturity and duration will, on average, equal the general market.
 
  Additionally, the Adviser attempts to emphasize relative values within se-
lected maturity ranges. Interest rate spreads between different quality rang-
es, by types of issues and within coupon areas are monitored, and the Portfo-
lio will be structured to take advantage of relative values within these
areas. Marketability of individual issues and diversification within the Port-
folio will be emphasized. The Portfolio will hold, under normal circumstances,
no more than 10% of its assets in any single non-governmental issue.
 
                           OTHER INVESTMENT POLICIES
 
SHORT-TERM INVESTMENTS
  In order to earn a return on uninvested assets, meet anticipated redemp-
tions, or for temporary defensive purposes, the Portfolio may invest a portion
of its assets in domestic and foreign money market instruments including cer-
tificates of deposit, bankers' acceptances, time deposits, U.S. Government ob-
ligations, U.S. Government agency securities, short-term corporate debt secu-
rities, and commercial paper rated A-1 or A-2 by S&P or Prime-1 or Prime-2 by
Moody's or if unrated, determined by the Adviser to be of comparable quality.
 
  Time deposits maturing in more than seven days will not be purchased by the
Portfolio, and time deposits maturing from two business days through seven
calendar days will not exceed 15% of the total assets of the Portfolio. The
Portfolio will
 
                                       5
<PAGE>
 
not invest in any security issued by a commercial bank unless (i) the bank has
total assets of at least $1 billion, or the equivalent in other currencies,
(ii) in the case of U.S. banks, it is a member of the Federal Deposit Insur-
ance Corporation, and (iii) in the case of foreign branches of U.S. banks, the
security is, in the opinion of the Adviser, of an investment quality compara-
ble with other debt securities which may be purchased by the Portfolio.
 
  The Fund has received permission from the Securities and Exchange Commission
(the "SEC") to deposit the daily uninvested cash balances of the Fund's Port-
folios, as well as cash for investment purposes, into one or more joint ac-
counts and to invest the daily balance of the joint accounts in the following
short-term investments: fully collateralized repurchase agreements, interest-
bearing or discounted commercial paper including dollar-denominated commercial
paper of foreign issuers, and any other short-term money market instruments
including variable rate demand notes and tax-exempt money instruments. By en-
tering into these investments on a joint basis, it is expected that a Portfo-
lio may earn a higher rate of return on investments relative to what it could
earn individually.
 
  The Fund has received permission from the SEC for each of its Portfolios to
invest, for cash management purposes, the greater of 5% of its total assets or
$2.5 million in the Fund's DSI Money Market Portfolio. (See "INVESTMENT
COMPANIES.")
 
REPURCHASE AGREEMENTS
  The Portfolio may invest in repurchase agreements collateralized by U.S.
Government securities, certificates of deposit, and certain bankers' accept-
ances and other securities outlined above under "SHORT-TERM INVESTMENTS." In a
repurchase agreement, a Portfolio buys a security and simultaneously commits
to sell that security back at an agreed upon price plus an agreed upon market
rate of interest. Under a repurchase agreement, the seller is also required to
maintain the value of securities subject to the agreement at not less than
100% of the repurchase price. The value of the securities purchased will be
evaluated daily, and the Adviser will, if necessary, require the seller to
maintain additional securities to ensure that the value is in compliance with
the previous sentence.
 
  The use of repurchase agreements involves certain risks. For example, a de-
fault by the seller of the agreement may cause a Portfolio to experience a
loss or delay in the liquidation of the collateral securing the repurchase
agreement. A Portfolio might also incur disposition costs in liquidating the
collateral. While the Fund's management acknowledges these risks, it is ex-
pected that they can be controlled through stringent security selection crite-
ria and careful monitoring procedures.
 
  The Fund has received permission from the SEC to pool daily uninvested cash
balances of the Fund's Portfolios in order to invest in repurchase agreements
on a
 
                                       6
<PAGE>
 
joint basis. By entering into joint repurchase agreements, a Portfolio may in-
cur lower transaction costs and earn higher rates of interest on joint repur-
chase agreements. The Portfolio's contribution would determine its return from
a joint repurchase agreement. (See "SHORT-TERM INVESTMENTS.")
 
LENDING OF SECURITIES
  The Portfolio may lend its investment securities to qualified institutional
investors who need to borrow securities in order to complete certain transac-
tions. The Portfolio will not loan portfolio securities to the extent that
greater than one-third of its assets at fair market value, would be committed
to loans. By lending its investment securities, the Portfolio attempts to in-
crease its income through the receipt of interest on the loan. Any gain or
loss in the market price of the securities loaned that might occur during the
term of the loan would be for the account of the Portfolio. The Portfolio may
lend its investment securities to qualified brokers, dealers, domestic and
foreign banks or other financial institutions, so long as the terms, the
structure and the aggregate amount of such loans are not inconsistent with the
Investment Company Act of 1940, as amended (the "1940 Act"). All relevant
facts and circumstances, including the creditworthiness of the broker, dealer
or institution, will be considered in making decisions with respect to the
lending of securities, subject to review by the Fund's Board of Directors.
 
  At the present time, the SEC does not object if an investment company pays
reasonable negotiated fees in connection with loaned securities so long as
such fees are set forth in a written contract and approved by the investment
company's Board of Directors. The Portfolio will continue to retain any voting
rights with respect to the loaned securities. If a material event occurs af-
fecting an investment on loan, the loan must be called and the securities vot-
ed.
 
WHEN-ISSUED, FORWARD DELIVERY AND DELAYED SETTLEMENT SECURITIES
  The Portfolio may purchase and sell securities on a "when-issued," "delayed
settlement," or "forward delivery" basis. "When-issued" or "forward delivery"
refers to securities whose terms and indenture are available, and for which a
market exists, but which are not available for immediate delivery. When-issued
and forward delivery transactions may be expected to occur a month or more be-
fore delivery is due. Delayed settlement is a term used to describe settlement
of a securities transaction in the secondary market which will occur sometime
in the future. No payment or delivery is made by the Portfolio until it re-
ceives delivery or payment from the other party to any of the above transac-
tions. It is possible that the market price of the securities at the time of
delivery may be higher or lower than the purchase price. The Portfolio will
maintain a separate account of cash or liquid securities at least equal to the
value of purchase commitments until payment is made. Typically, no income ac-
crues on securities purchased on a delayed deliv-
 
                                       7
<PAGE>
 
ery basis prior to the time delivery is made although the Portfolio may earn
income on securities it has deposited in a segregated account.
 
  The Portfolio engages in these types of purchases in order to buy securities
that fit with its investment objectives at attractive prices -- not to in-
crease its investment leverage.
 
PORTFOLIO TURNOVER
  It is expected that the annual portfolio turnover rate for the Portfolio
will not exceed 200%. In addition to Portfolio trading costs, higher rates of
portfolio turnover may result in the realization of capital gains. To the ex-
tent net short-term capital gains are realized, any distributions resulting
from such gains are considered ordinary income for federal income tax purpos-
es. (See "DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES" for more informa-
tion on taxation.) The Portfolio will not normally engage in short-term trad-
ing, but reserves the right to do so.
 
INVESTMENT COMPANIES
  The Portfolio reserves the right to invest up to 10% of its total assets,
calculated at the time of investment, in the securities of other open-end or
closed-end investment companies. No more than 5% of the Portfolio's total as-
sets may be invested in the securities of any one investment company nor may
it acquire more than 3% of the voting securities of any other investment com-
pany. The Portfolio will indirectly bear its proportionate share of any man-
agement fees paid by an investment company in which it invests in addition to
the advisory fee paid by the Portfolio.
 
  The Fund has been granted permission by the SEC to allow each of its Portfo-
lios to invest the greater of 5% of its total assets or $2.5 million in the
Fund's DSI Money Market Portfolio for cash management purposes provided that
the investment is consistent with the investing Portfolio's investment poli-
cies and restrictions. Based upon a Portfolio's assets invested in the DSI
Money Market Portfolio, an investing Portfolio's adviser will waive its in-
vestment advisory fee and any other fees earned as a result of a Portfolio's
investment in the DSI Money Market Portfolio. An investing Portfolio will bear
expenses of the DSI Money Market Portfolio on the same basis as all of its
other shareholders.
 
RESTRICTED SECURITIES
  The Portfolio may purchase restricted securities that are not registered for
sale to the general public but which are eligible for resale to qualified in-
stitutional investors under Rule 144A of the Securities Act of 1933. Under the
supervision of the Fund's Board of Directors, the Adviser determines the li-
quidity of such investments by considering all relevant factors. Provided that
a dealer or institutional trading market in such securities exists, these re-
stricted securities are not treated as
 
                                       8

illiquid securities for purposes of the Portfolio's investment limitations.
The Portfolio may also invest up to 15% of its net assets in illiquid securi-
ties. The prices realized from the sales of these securities could be more or
less than those originally paid by the Portfolio or less than what may be con-
sidered the fair value of such securities.
 
MORTGAGE-BACKED SECURITIES
  Mortgage-backed securities are collateralized by pools of mortgages assem-
bled for subsequent sale to investors by various governmental agencies and
sponsored organizations as well as by private issuers. The underlying assets
collateralizing the mortgage-backed securities may include single-family, mul-
tifamily and commercial properties. The two fundamental forms of mortgage-
backed securities are pass-throughs and collateralized mortgage obligations
("CMOs"). Pass-throughs produce monthly payments of principal and interest
from the underlying mortgages. CMOs divide the cash flows generated from the
underlying mortgages or mortgage pass-through securities into different seg-
ments known as "tranches" which are then retired sequentially over time in or-
der of priority. The market value and yield of mortgage-backed securities will
fluctuate due to market interest rate change and early prepayments of the un-
derlying mortgages. As prepayment rates on mortgages vary widely, it is diffi-
cult to accurately predict the average maturity of a particular pool of mort-
gages or tranches of CMOs. Although mortgage-backed securities may offer
higher yields than those available from other types of securities, they may be
less effective than other types of securities as a means of "locking in" an
attractive rate for an extended period because of the prepayment feature. Pre-
payment risk has two important effects. First, like bonds in general, mort-
gage-backed securities will generally decline in price when interest rates
rise. Second, when interest rates fall and additional mortgage prepayments
must be reinvested at lower interest rates, the Portfolio's rate of dividend
income may be reduced. Mortgage-backed securities in which the Portfolio may
invest will either carry a guarantee from an agency of the U.S. Government or
a private issuer of the timely payment of principal and interest or are suit-
ably structured to be considered by the Adviser to be of investment grade
quality.
 
ASSET-BACKED SECURITIES
  Asset-backed securities are collateralized by short maturity loans such as
automobile receivables, credit card receivables, or other types of receivables
or assets, the payments from which are passed through to the security holder.
Credit support for asset-backed securities may be based on the underlying as-
sets and/or provided through credit enhancements by a third party. Credit en-
hancement techniques include letters of credit, insurance bonds, limited guar-
antees (which are generally provided by the issuer), senior-subordinated
structures and over-collateralization. The value of these securities may be
significantly affected by changes in interest rates, the market's perceptions
of the issuers and the creditworthiness of the parties involved.

YANKEE BONDS
  Yankee bonds are dollar-denominated bonds issued inside the United States by
foreign entities. Investment in these securities involve certain risks which
are not typically associated with investing in domestic securities. Non U.S.-
based issuers are not subject to the same accounting, auditing and financial
reporting standards as are domestic issuers. There may be less publicly-avail-
able information about non-U.S.-based issuers which may make it difficult to
make investment decisions. Political factors may have an impact in the form of
confiscatory taxation, expropriation or political instability in international
markets. Some foreign governments also levy withholding taxes against dividend
and interest income. Although in some countries a portion of the taxes is re-
coverable, the non-recovered portion of foreign withholding taxes will reduce
the income the Portfolio receives from the companies comprising its invest-
ments.
 
                            INVESTMENT LIMITATIONS
 
  The Portfolio will not:
 
  (a) with respect to 75% of its assets, invest more than 5% of its total
      assets at the time of purchase in the securities of any single issuer
      (other than obligations issued or guaranteed as to principal and in-
      terest by the U.S. government or any of its agencies or instrumentali-
      ties);
  (b) with respect to 75% of its assets, purchase more than 10% of any class
      of the outstanding voting securities of any issuer;
  (c) invest more than 5% of its assets at the time of purchase in the secu-
      rities of companies that have (with predecessors) a continuous operat-
      ing history of less than 3 years;
  (d) invest more than 25% of its assets in companies within a single indus-
      try; however, there are no limitations on investments made in instru-
      ments issued or guaranteed by the U.S. Government and its agencies
      when the portfolio adopts a temporary defensive position;
  (e) make loans except (i) by purchasing bonds, debentures or similar obli-
      gations which are publicly distributed, (including repurchase agree-
      ments provided, however, that repurchase agreements maturing in more
      than seven days, together with securities which are not readily mar-
      ketable, will not exceed 15% of the Portfolio's net assets), and (ii)
      by lending its portfolio securities to banks, brokers, dealers and
      other financial institutions so long as such loans are not inconsis-
      tent with the 1940 Act or the Rules and Regulations or interpretations
      of the SEC thereunder;
  (f) (i) borrow, except from banks and as a temporary measure for extraor-
      dinary or emergency purposes and then, in no event, in excess of 33
      1/3% of the Portfolio's gross assets valued at the lower of market or
      cost, and (ii) a Portfolio may not purchase additional securities when
      borrowings exceed 5% of total assets; or
 
                                      10
<PAGE>
 
  (g) pledge, mortgage or hypothecate any of its assets to an extent greater
      than 33 1/3% of its total assets at fair market value.
 
  The Portfolio's investment objective and investment limitations (a), (b),
(d), (e) and (f)(i) listed above are fundamental policies and may be changed
only with the approval of the holders of a majority of the outstanding voting
securities of the Portfolio. The other investment limitations described here
and those not specified as fundamental in the SAI as well as the Portfolio's
investment policies are not fundamental and the Fund's Board of Directors may
change them without shareholder approval.
 
                              PURCHASE OF SHARES
 
  Shares of the Portfolio are offered through UAM Fund Distributors, Inc. (the
"Distributor"), without a sales commission at the net asset value per share
next determined after an order is received by the Fund and payment is received
by the Custodian. (See "VALUATION OF SHARES.") The minimum initial investment
required is $2,500. The minimum initial investment for 401(k) plans is $500.
The minimum initial investment for IRA accounts is $500. The minimum initial
investment for spousal IRA accounts is $250. Certain exceptions may be made by
the officers of the Fund.
 
  Shares of the Portfolio may be purchased by customers of brokers-dealers or
other financial intermediaries ("Service Agents") which have established a
shareholder servicing relationship with the Fund on behalf of their customers.
Service Agents may impose additional or different conditions on purchases or
redemptions of Portfolio shares and may charge transaction or other account
fees. Each Service Agent is responsible for transmitting to its customers a
schedule of any such fees and information regarding additional or different
purchase or redemption conditions. Shareholders who are customers of Service
Agents should consult their Service Agent for information regarding these fees
and conditions. Amounts paid to Service Agents may include transaction fees
and/or service fees paid by the Fund from the Fund assets attributable to the
Service Agent, which would not be imposed if shares of the Portfolio were pur-
chased directly from the Fund or the Distributor. Service Agents may provide
shareholder services to their customers that are not available to a share-
holder dealing directly with the Fund. A salesperson and any other person en-
titled to receive compensation for selling or servicing Portfolio shares may
receive different compensation with respect to one particular class of shares
over another in the Fund.
 
  Service Agents may enter confirmed purchase orders on behalf of their cus-
tomers. If shares of a Portfolio are purchased in this manner, the Service
Agent must receive your investment order before the close of trading on the
New York Stock Exchange ("NYSE"), and transmit it to the Fund's Sub-Transfer
Agent, Chase Global Funds Services Company, prior to the close of its business
day to
 
                                      11
<PAGE>
 
receive that day's share price. Proper payment for the order must be received
by the Sub-Transfer Agent no later than the time when the Portfolio is priced
on the following business day. Service Agents are responsible to their custom-
ers and the Fund for timely transmission of all subscription and redemption
requests, investment information, documentation and money.

OTHER PURCHASE INFORMATION
  Investments received by 4 p.m. Eastern Time (ET) (the close of the NYSE)
will be invested at the share price calculated after the NYSE closes on that
day. Investments received after the close of the NYSE will be executed at the
price computed on the next day the NYSE is open. The Fund reserves the right,
in its sole discretion, to suspend the offering of shares of the Portfolio or
to reject purchase orders when, in the judgment of management, such suspension
or rejection is in the best interests of the Fund. Purchases of the Portfo-
lio's shares will be made in full and fractional shares of the Portfolio cal-
culated to three decimal places. Certificates for fractional shares will not
be issued. Certificates for whole shares will not be issued except at the
written request of the shareholder.
 
IN-KIND PURCHASES
  If accepted by the Fund, shares of the Portfolio may be purchased in ex-
change for securities which are eligible for acquisition by the Portfolio, as
described in this Prospectus. Securities to be exchanged which are accepted by
the Fund will be valued as described under "VALUATION OF SHARES" at the next
determination of net asset value after acceptance. Shares issued by the Port-
folio in exchange for securities will be issued at net asset value determined
as of the same time. All dividends, interest, subscription, or other rights
pertaining to such securities shall become the property of the Portfolio and
must be delivered to the Fund by the investor upon receipt from the issuer.
Securities acquired through an in-kind purchase will be acquired for invest-
ment and not for immediate resale.
 
  The Fund will not accept securities in exchange for shares of the Portfolio
unless:
    . at the time of exchange, such securities are eligible to be in-
      cluded in the Portfolio (current market quotations must be readily
      available for such securities);
    . the investor represents and agrees that all securities offered to
      be exchanged are liquid securities and not subject to any restric-
      tions upon their sale by the Portfolio under the Securities Act of
      1933, or otherwise; and
 
                                      13
<PAGE>
 
    . the value of any such securities (except U.S. Government securi-
      ties) being exchanged together with other securities of the same
      issuer owned by the Portfolio will not exceed 5% of the net assets
      of the Portfolio immediately after the transaction.
 
  Investors who are subject to Federal taxation upon exchange may realize a
gain or loss for Federal income tax purposes depending upon the cost of secu-
rities or local currency exchanged. Investors interested in such exchanges
should contact the Adviser.
 
                             REDEMPTION OF SHARES
 
  Shares of the Portfolio may be redeemed by mail or telephone at any time,
without cost, at the net asset value of the Portfolio next determined after
receipt of the redemption request. No charge is made for redemptions. Any re-
demption may be more or less than the purchase price of the shares depending
on the market value of investment securities held by the Portfolio.
 
BY MAIL
  Address requests for redemption to the UAM Funds Service Center. Requests to
redeem shares must include:
    . share certificates, if issued;
    . a letter of instruction or an assignment specifying the number of
      shares or dollar amount to be redeemed, signed by all registered
      owners of the shares in the exact names in which they are regis-
      tered;
    . any required signature guarantees (see "SIGNATURE GUARANTEES"); and
    . any other necessary legal documents, if required, in the case of
      estates, trusts, guardianships, custodianships, corporations, pen-
      sion and profit sharing plans and other organizations.
 
BY TELEPHONE
  A redemption request by telephone requires the following:
    . establish the telephone redemption privilege (and if desired, the
      wire redemption privilege) by completing appropriate sections of
      the Application; and
    . call the Fund and instruct that the redemption proceeds be mailed
      to you or wired to your bank.
 
  The following tasks cannot be accomplished by telephone:
    . changing the name of the commercial bank or the account designated
      to receive redemption proceeds (this can be accomplished only by a
      written request signed by each shareholder, with each signature
      guaranteed); and
    . redemption of certificated shares by telephone.
 
                                      14
<PAGE>
 
  The Fund and its Sub-Transfer Agent will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine, and they may
be liable for any losses if they fail to do so. These procedures include re-
quiring the investor to provide certain personal identification at the time an
account is opened, as well as prior to effecting each transaction requested by
telephone. In addition, all telephone transaction requests will be recorded
and investors may be required to provide additional telecopied written in-
structions of such transaction requests. The Fund or Sub-Transfer Agent may be
liable for any losses due to unauthorized or fraudulent telephone instructions
if the Fund or the Sub-Transfer Agent does not employ the procedures described
above. Neither the Fund nor the Sub-Transfer Agent will be responsible for any
loss, liability, cost or expense for following instructions received by tele-
phone that it reasonably believes to be genuine.
 
SIGNATURE GUARANTEES
  Signature guarantees are required for the following redemptions:
    . redemptions where the proceeds are to be sent to someone other than
      the registered shareowner(s);
    . redemptions where the proceeds are to be sent to someplace other
      than the registered address; or
    . share transfer requests.
 
  Signature guarantees will be accepted from any eligible guarantor institu-
tion which participates in a signature guarantee program. Eligible guarantor
institutions include banks, brokers, dealers, credit unions, national securi-
ties exchanges, registered securities associations, clearing agencies and sav-
ings associations. Broker-dealers guaranteeing signatures must be a member of
a clearing corporation or maintain net capital of at least $100,000. Credit
unions must be authorized to issue signature guarantees.
 
OTHER REDEMPTION INFORMATION
  Normally, the Fund will make payment for all shares redeemed under proper
procedures within one business day of and no more than seven days after the
receipt of the request, or earlier if required under applicable law. The Fund
may suspend the right of redemption or postpone the date at times when both
the NYSE and Custodian Bank are closed, or under any emergency circumstances
determined by the SEC.
 
  If the Board of Directors determines that it would be detrimental to the
best interests of remaining shareholders of the Fund to make payment wholly or
partly in cash, the Fund may pay redemption proceeds in whole or in part by a
distribution in-kind of liquid securities held by a Portfolio in lieu of cash
in conformity with applicable rules of the SEC. Investors may incur brokerage
charges on the sale of portfolio securities received in payment of redemp-
tions.

                             SHAREHOLDER SERVICES
 
EXCHANGE PRIVILEGE
  Institutional Class Shares of the Portfolio may be exchanged for Institu-
tional Class Shares of any other UAM Funds Portfolio. (See the list of Portfo-
lios of the UAM Funds at the end of this Prospectus.) Exchange requests should
be made by calling the Fund or by writing to the UAM Funds Service Center.
 
  Any exchange will be based on the net asset value of the shares involved.
There is no sales commission or charge of any kind for an exchange. Before
making an exchange into a Portfolio, a shareholder should read its Prospectus
and consider the investment objectives of the Portfolio to be purchased. Call
the UAM Funds Service Center for a copy of the Prospectus for the Portfolio(s)
in which you are interested. Exchanges can only be made with Portfolios that
are qualified for sale in a shareholder's state of residence.
 
  Exchange requests may be made either by mail or telephone. Telephone ex-
changes will be accepted only if the certificates for the shares to be ex-
changed have not been issued to the shareholder and if the registration of the
two accounts will be identical. Requests for exchanges received prior to 4
p.m. ET will be processed as of the close of business on the same day. Re-
quests received after 4 p.m. ET will be processed on the next business day.
The Board of Directors may limit the frequency and amount of exchanges permit-
ted. For additional information regarding responsibility for the authenticity
of telephoned instructions, see "REDEMPTION OF SHARES -- BY TELEPHONE."
 
  An exchange into another UAM Funds Portfolio is a sale of shares and may re-
sult in a gain or loss for income tax purposes. The Fund may modify or termi-
nate the exchange privilege at any time.
 
                              VALUATION OF SHARES
 
  The net asset value of the Portfolio is determined by dividing the value of
the Portfolio's assets attributable to the class, less any liabilities attrib-
utable to the class, by the number of shares outstanding attributable to the
class. The net asset value per share of the Portfolio is determined as of the
close of the NYSE on each day that the NYSE is open for business.
 
  Bonds and other fixed income securities are valued according to the broadest
and most representative market, which will ordinarily be the over-the-counter
market. Bonds and other fixed income securities may be valued on the basis of
prices provided by a pricing service when such prices are believed to reflect
the fair market value of such securities. Securities purchased with remaining
maturities of 60 days or less are valued at amortized cost when the Board of
Directors determines that amortized cost reflects fair value.
 
                                      16
<PAGE>
 
  The value of other assets and securities for which no quotations are readily
available (including restricted securities) is determined in good faith at
fair value using methods determined by the Directors.
 
                           PERFORMANCE CALCULATIONS
 
  The Portfolio measures performance by calculating yield and total return.
Both yield and total return figures are based on historical earnings and are
not intended to indicate future performance.
 
  Yield refers to the income generated by an investment in the Portfolio over
a given period of time, expressed as an annual percentage rate. Yields are
calculated according to a standard that is required for all funds. As this
differs from other accounting methods, the quoted yield may not equal the in-
come actually paid to shareholders.
 
  Total return is the change in value of an investment in the Portfolio over a
given period, assuming reinvestment of any dividends and capital gains. A cu-
mulative or aggregate total return reflects actual performance over a stated
period of time. An average annual total return is a hypothetical rate of re-
turn that, if achieved annually, would have produced the same cumulative total
return if performance had been constant over the entire period.
 
  Performance is calculated separately for Institutional Class and Service
Class Shares. Dividends paid by the Portfolio with respect to Institutional
Class and Service Class Shares, to the extent any dividends are paid, will be
calculated in the same manner at the same time on the same day and will be in
the same amount, except that service fees, distribution charges and any incre-
mental transfer agency costs relating to Service Class Shares will be borne
exclusively by that class.
 
  The Portfolio's performance may be compared to data prepared by independent
services which monitor the performance of investment companies, data reported
in financial and industry publications, and various indices as further de-
scribed in the Portfolio's SAI. This information may also be included in sales
literature and advertising.
 
  Since this is a new Portfolio, we can offer no information about past port-
folio investment performance. When this information becomes available, you
will find it, together with comparisons to appropriate indices, in the Portfo-
lio's Annual Report to Shareholders, which may be obtained without charge upon
request to the Fund by writing to the address or calling the phone number on
the cover of this Prospectus.

               DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES
 
DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
  The Portfolio will normally distribute substantially all of its net invest-
ment income (for tax purposes) to shareholders in quarterly dividends. If any
net capital gains are realized, the Portfolio will normally distribute them
annually.
 
  All dividends and capital gains distributions will be automatically rein-
vested in additional shares of the Portfolio unless the Fund is notified in
writing that the shareholder elects to receive distributions in cash.
 
FEDERAL TAXES
  The Portfolio intends to qualify as a "regulated investment company" under
subchapter M of the Internal Revenue Code of 1986, as amended, for federal in-
come tax purposes and to meet all other requirements that are necessary for it
(but not its shareholders) to be exempt from federal taxes on income and gains
paid to shareholders in the form of dividends. To do this, the Portfolio must,
among other things, distribute substantially all of its ordinary income and
net capital gains on a current basis and maintain a portfolio of investments
which satisfies certain diversification criteria.
 
  Dividends paid by the Portfolio from net investment income, whether in cash
or reinvested in shares, are taxable to shareholders as ordinary income.
Short-term capital gains will be taxed as ordinary income. Long-term capital
gains distributions are taxed as long-term capital gains. Shareholders will be
notified annually of dividend income earned for tax purposes.
 
  Dividends declared in October, November and December to shareholders of rec-
ord in such a month will be treated as if they had been paid by the Fund and
received by the shareholders on December 31 of the same calendar year, pro-
vided that the dividends are paid before February of the following year.
 
  The Fund is required by Federal law to withhold 31% of reportable payments
paid to shareholders who have not complied with IRS regulations. In order to
avoid this withholding requirement, you must certify that your Social Security
or Taxpayer Identification Number you have provided is correct and that either
you are not currently subject to backup withholding or you are exempt from
backup withholding. This certification must be made on the Application or on a
separate form supplied by the Fund.
 
  Dividends and interest received by the Portfolio may give rise to withhold-
ing and other taxes imposed by foreign countries. These taxes reduce the Port-
folio's dividends but are included in the taxable income reported on your tax
statement if the Portfolio qualifies for this tax treatment and elects to pass
it through to you. Consult a tax adviser for more information regarding deduc-
tions and credits for foreign taxes.

  The Adviser has voluntarily agreed to waive a portion of its advisory fees
and to assume expenses otherwise payable by the Portfolio to reduce its ex-
pense ratio. As of the date of this Prospectus, the Adviser has agreed to keep
the Bond Portfolio Institutional Class Shares from exceeding 0.50% of average
daily net assets. The Fund will not reimburse the Adviser for any advisory
fees that are waived or Portfolio expenses that the Adviser may bear on behalf
of the Portfolio for a given fiscal year.
 
  The Adviser may compensate its affiliated companies for referring investors
to the Portfolio. The Distributor, UAM, the Adviser, or any of their affili-
ates, may, at its own expense, compensate a Service Agent or other person for
marketing, shareholder servicing, record-keeping and/or other services per-
formed with respect to the Fund, a Portfolio or any Class of Shares of a Port-
folio. Payments made for any of these purposes may be made from its revenues,
its profits or any other source available to it. When such service arrange-
ments are in effect, they are made generally available to all qualified serv-
ice providers.
 
  The Distributor, the Adviser, and certain of their affiliates also partici-
pate, at the date of this Prospectus, in an arrangement with Smith Barney Inc.
under which Smith Barney provides certain defined contribution plan marketing
and shareholder services of its Consulting Group and receives .15 of 1% of the
daily net asset value of Institutional Class Shares held by Smith Barney's el-
igible customer accounts in addition to amounts payable to all selling deal-
ers. The Fund also compensates Smith Barney for services it provides to cer-
tain defined contribution plan shareholders that are not otherwise provided by
UAMFSI.
 
                       ADVISER'S HISTORICAL PERFORMANCE
   
  Set forth below are certain performance data provided by the Adviser relat-
ing to the composite of separately managed fixed income accounts of clients of
the Adviser. These accounts have the same investment objective as the Portfo-
lio, and were managed using substantially similar, though not in all cases
identical, investment strategies, techniques and policies as those contem-
plated for use by the Adviser in managing the Portfolio. The performance data
for the managed accounts is net of all fees and expenses. The investment re-
turns of the Portfolio may differ from those of the separately managed ac-
counts because such separately managed accounts may have fees and expenses
that differ from those of the Portfolio. Further, the separately managed ac-
counts are not subject to investment limitations, diversification require-
ments, and other restrictions imposed by the 1940 Act and Internal Revenue
Code; such conditions, if applicable, may have lowered the returns for the
separately managed accounts. The results presented are not intended to predict
or suggest the return to be experienced by the Portfolio or the return an in-
vestor might achieve by investing in the Portfolio.

Notes:
1. The annualized return is calculated from monthly data, allowing for com-
   pounding. The formula used is in accordance with the acceptable methods set
   forth by the Association for Investment Management Research, the Bank Ad-
   ministration Institute, and the Investment Counsel Association of America.
   Market Value of the account was the sum of the account's total assets, in-
   cluding cash, cash equivalents, short-term investments, and securities val-
   ued at current market prices.
 
                                      21
<PAGE>
 
   
2. The cumulative return means that $1 invested in the account on 1/1/80 had
   grown to $6.83 by June 30, 1997.     
3. The 17-year mean is the arithmetic average of the annual returns for the
   calendar years listed.
4. The Lehman Brothers Aggregate Bond Index is an unmanaged index which as-
   sumes reinvestment of dividends and is generally considered representative
   of securities similar to those invested in by the Adviser for the purpose
   of the composite performance numbers set forth above.
   
5. During the period shown (1/1/80-6/30/97), fees on the Adviser's individual
   accounts ranged from 0.20% to 0.30% (20 basis points to 30 basis points).
   The Adviser's returns presented above are net of the maximum fee of 0.30%.
   Net returns to investors vary depending on the management fee.     
 
                            ADMINISTRATIVE SERVICES
 
  UAM Fund Services, Inc. ("UAMFSI"), a wholly-owned subsidiary of UAM, is re-
sponsible for performing and overseeing administrative, fund accounting, divi-
dend disbursing and transfer agent services provided to the Fund and its Port-
folios. UAMFSI's principal office is located at 211 Congress Street, Boston,
MA 02110. UAMFSI has subcontracted some of these services to Chase Global
Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan Bank, by
a Mutual Funds Service Agreement dated June 30, 1997. CGFSC is located at 73
Tremont Street, Boston, MA 02108.
 
  Each Portfolio pays UAMFSI a two part monthly fee: a Portfolio-specific fee
which is retained by UAMFSI and a sub-administration fee which UAMFSI in turn
pays to CGFSC. The Portfolio-specific fee is calculated from the aggregate net
assets of the Portfolio at the following annual rate:

   Sirach Bond Portfolio................................................. 0.04%
</TABLE>
 
  CGFSC's monthly fee for its services is calculated on an annualized basis as
follows:
  0.19 of 1% of the first $200 million of combined Fund assets;
  0.11 of 1% of the next $800 million of combined Fund assets;
  0.07 of 1% of combined Fund assets in excess of $1 billion but less than
  $3 billion;
  0.05 of 1% of combined Fund assets in excess of $3 billion.
 
  Fees are allocated among the Portfolios on the basis of their relative as-
sets and are subject to a graduated minimum fee schedule per Portfolio, which
starts at $2,000 per month and increases to $70,000 annually after two years.
If a separate class of shares is added to a Portfolio, its minimum annual fee
increases by $20,000.

                                  DISTRIBUTOR
 
  UAM Fund Distributors, Inc., a wholly-owned subsidiary of UAM, with its
principal office located at 211 Congress Street, Boston, MA 02110, distributes
shares of the Fund. Under the Distribution Agreement (the "Agreement"), the
Distributor, as agent of the Fund, agrees to use its best efforts as sole dis-
tributor of Fund shares. The Distributor does not receive any fee or other
compensation under the Agreement with respect to the Institutional Class
Shares offered in this Prospectus. The Agreement continues in effect as long
as it is approved at least annually by the Fund's Board of Directors. Those
approving the Agreement must include a majority of Directors who are neither
parties to the Agreement nor interested persons of any such party. The Agree-
ment provides that the Fund will bear costs of registration of its shares with
the SEC and various states as well as the printing of its prospectuses, its
SAIs and its reports to shareholders.
 
                            PORTFOLIO TRANSACTIONS
 
  The Advisory Agreements for the Fund's Portfolios authorize the Adviser to
select the brokers or dealers that will execute the purchases and sales of in-
vestment securities for each Portfolio. The Agreements direct the Adviser to
use its best efforts to obtain the best available price and most favorable ex-
ecution for all transactions of the Portfolios. If consistent with the inter-
ests of the Portfolios, the Adviser may select brokers on the basis of re-
search, statistical and pricing services these brokers provide to the Portfo-
lios in addition to required Adviser services. Such brokers may be paid a
higher commission than that which another qualified broker would have charged
for effecting the same transaction, provided that such commissions are paid in
compliance with the Securities Exchange Act of 1934, as amended, and that the
Adviser determines in good faith that the commission is reasonable in terms
either of the transaction or the overall responsibility of the Adviser to the
Portfolios and the Adviser's other clients.
 
  Although not a typical practice, the Adviser may place portfolio orders with
qualified broker-dealers who refer clients to the Adviser.
 
  If a purchase or sale of securities is consistent with the investment poli-
cies of a Portfolio and one or more other clients served by the Adviser is
considering a purchase at or about the same time, transactions in such securi-
ties will be allocated among the Portfolio and clients in a manner deemed fair
and reasonable by the Adviser. Although there is no specified formula for al-
locating such transactions, allocations are subject to periodic review by the
Fund's Directors.
 
                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES AND VOTING RIGHTS
  The Fund was organized as a Maryland corporation on October 11, 1988 under
the name "ICM Fund, Inc." On January 18, 1989, the name of the Fund
 
                                      23
<PAGE>
 
was changed to "The Regis Fund, Inc." On October 31, 1995, the name of the
Fund was changed to "UAM Funds, Inc."
 
  The Fund's Articles of Incorporation, as amended, permit the Directors to
issue three billion shares of common stock, with an $.001 par value. The Di-
rectors have the power to designate one or more series or classes of shares of
common stock and to classify or reclassify any unissued shares without further
action by shareholders. At its discretion, the Board of Directors may create
additional Portfolios and classes of shares.
 
  The shares of each Portfolio are fully paid and nonassessable, and have no
preference as to conversion, exchange, dividends, retirement or other features
and no pre-emptive rights. They have noncumulative voting rights, which means
that holders of more than 50% of shares voting for the election of Directors
can elect 100% of the Directors. A shareholder is entitled to one vote for
each full share held (and a fractional vote for each fractional share held),
then standing in his name on the books of the Fund.
 
  The persons or organizations owning 25% or more of the outstanding shares of
a Portfolio may be presumed to "control" (as that term is defined in the 1940
Act) such Portfolio. As a result, those persons or organizations could have
the ability to vote a majority of the shares of the Portfolio on any matter
requiring the approval of shareholders of the Portfolio.
 
  Both Institutional Class and Institutional Service Class Shares represent an
interest in the same assets of a Portfolio. Service Class Shares bear certain
expenses related to shareholder servicing, and may bear expenses related to
distribution. Service Class shares have exclusive voting rights for matters
relating to such distribution expenditures. Information about the Service
Class Shares of the Portfolio is available upon request by contacting the UAM
Funds Service Center.
 
  Annual meetings will not be held except as required by the 1940 Act and
other applicable laws. The Fund has undertaken that its Directors will call a
meeting of shareholders if such a meeting is requested in writing by the hold-
ers of not less than 10% of the outstanding shares of the Fund. The Fund will
assist shareholder communications in such matters to the extent required by
the undertaking.
 
CUSTODIAN
  The Chase Manhattan Bank serves as Custodian of the Fund's assets.
 
INDEPENDENT ACCOUNTANTS
  Price Waterhouse LLP are the independent accountants for the Fund.
 
REPORTS

                      PROSPECTUS -- OCTOBER 23, 1997     
 
  UAM Funds, Inc. (the "Fund") is an open-end, management investment company,
known as a "mutual fund." The Fund consists of multiple series of shares
(known as "Portfolios"), each of which has different investment objectives and
policies. The Sirach Bond Portfolio currently offers two separate classes of
shares: Institutional Class Shares and Institutional Service Class Shares
("Service Class Shares"). Shares of each class represent equal, pro rata in-
terests in the Portfolio and accrue dividends in the same manner except that
Service Class Shares bear fees payable by the class (at the rate of .25% per
annum) to financial institutions for services they provide to the owners of
such shares. (See "SERVICE AND DISTRIBUTION PLANS.") The securities offered in
this Prospectus are shares of the Service Class of one diversified Portfolio
of the Fund managed by Sirach Capital Management, Inc.
 
  SIRACH BOND PORTFOLIO. The objective of the Sirach Bond Portfolio (the
"Portfolio") is to achieve above-average total return consistent with reason-
able risk to principal by investing primarily in dollar-denominated, invest-
ment grade fixed income securities.
 
  There can be no assurance that the Portfolio will achieve its stated objec-
tive.
   
  Keep this Prospectus for future reference. It contains information that you
should know before you invest. A Statement of Additional Information ("SAI")
containing additional information about the Fund has been filed with the Secu-
rities and Exchange Commission. The SAI is dated October 23, 1997 and has been
incorporated by reference into this Prospectus. For a free copy of the SAI
contact the UAM Funds Service Center at the address or telephone number above.
    
 THESE  SECURITIES HAVE NOT  BEEN APPROVED OR  DISAPPROVED BY THE  SECURITIES
   AND EXCHANGE COMMISSION, NOR HAS  THE SECURITIES AND EXCHANGE COMMISSION
     PASSED UPON THE  ACCURACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO
       THE CONTRARY IS A CRIMINAL OFFENSE.

 + The Adviser has voluntarily agreed to waive a portion of its advisory fees
   and to assume expenses otherwise payable by the Portfolio, if necessary, in
   order to reduce its expense ratio. As of the date of this Prospectus, the
   Adviser has agreed to keep the Bond Portfolio Service Class Shares from ex-
   ceeding 0.75% of its average net assets. The Fund will not reimburse the
   Adviser for any advisory fees that are waived or Portfolio expenses that
   the Adviser may bear on behalf of the Bond Portfolio for a given fiscal
   year. (See "SERVICE AND DISTRIBUTION PLANS.")
++ The Service Class Shares may bear service fees of 0.25%. Long-term share-
   holders may pay more than the economic equivalent of the maximum front-end
   sales charges permitted by rules of the National Association of Securities
   Dealers, Inc. (See "SERVICE AND DISTRIBUTIONS PLANS.")
 
  The table above shows various fees and expenses an investor would bear di-
rectly or indirectly. The expenses and fees set forth above for the Bond Port-
folio

are based on estimates. For purposes of calculating the expenses and fees set
forth above, the table assumes that the Bond Portfolio's average daily assets
will be $100 million. The effect of expense offsets on Total Operating Ex-
penses is excluded. It is estimated that, without the Adviser's fee waiver,
the Investment Advisory Fees would be 0.35% and the Total Operating Expenses
would be 0.89% of the Portfolio's average net assets.     
 
  The following example illustrates expenses a shareholder would pay on a
$1,000 investment over various time periods assuming (1) a 5% annual rate of
return and (2) redemption at the end of each time period. As noted in the ta-
ble above, the Portfolio charges no redemption fees of any kind.

firm founded in 1970, serves as investment adviser to six of the Fund's Port-
folios, including the Bond Portfolio. The Adviser presently manages approxi-
mately $7.5 billion in assets for institutional clients and high net worth in-
dividuals. (See "INVESTMENT ADVISER.")     
 
PURCHASE OF SHARES
  Shares of the Portfolio are offered through UAM Fund Distributors, Inc. (the

ceive cash distributions. (See "DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND
TAXES.")

                                 RISK FACTORS
 
  The value of the Portfolio's shares will fluctuate in response to changes in
market and economic conditions, as well as the financial conditions and pros-
pects of the issuers in which the Portfolio invests. Prospective investors
should consider the following: (1) In general, the Portfolio will not trade
for short-term profits, but when circumstances warrant, investments may be
sold without regard to the length of time held. High rates of portfolio turn-
over may result in additional transaction costs and the realization of capital
gains. (See "PORTFOLIO TURNOVER"); (2) In addition, the Portfolio may use var-
ious investment practices that involve special considerations, including in-
vesting in repurchase agreements, when-issued, forward delivery and delayed
settlement securities and lending of securities. (See "OTHER INVESTMENT POLI-
CIES.")
 
                             INVESTMENT OBJECTIVE
 
  The objective of the Portfolio is to provide above-average total return con-
sistent with reasonable risk to principal by investing primarily in dollar-de-
nominated, investment grade fixed income securities of varying maturities. In-
come return is expected to be a predominant portion of the Portfolio's total
return. Any capital return on the Portfolio is dependent upon interest rate
movements. The capital return from the Portfolio will vary according to, among
other factors, interest rate changes and the average maturity (duration) of
the Portfolio.
 
  There can be no assurance that the Portfolio will achieve its stated objec-
tive.
 
                              INVESTMENT POLICIES
 
  The Portfolio seeks to achieve its objective by investing at least 75% of
its total assets, under normal circumstances, in a diversified mix of dollar-
denominated, investment grade fixed income securities of varying maturities
including securities of the U.S. Government and its agencies, corporate bonds,
mortgage-backed securities, including CMOs, asset-backed securities, Yankee
bonds and various short-term instruments. (See "OTHER INVESTMENT POLICIES.")
 
  It is the Adviser's intention that the Portfolio's investments will be lim-
ited to those bonds having one of the four highest grades assigned by Moody's
Investors Services, Inc. ("Moody's") (Aaa, Aa, A or Baa ) or Standard and
Poor's Corporation ("S&P") (AAA, AA, A or BBB). Securities rated Baa by
Moody's or BBB by S&P may have speculative characteristics and could be more
sensitive to changes in the economy and the financial condition of issuers
than higher rated bonds. However, the Adviser reserves the right to retain se-
curities which are downgraded by one or both of the rating agencies if, in its
judgment, retention is warranted. Mortgage-backed securities in which the
Portfolio may invest will either carry a guarantee from an agency of the U.S.
Government or a private issuer of the
 
                                       4
<PAGE>
 
timely payment of principal and interest or are suitably structured to be con-
sidered by the Adviser to be of investment grade quality. The Portfolio's SAI
contains a more detailed description of corporate bond ratings.
 
  Regardless of the rating category, the credit quality of bonds can change
unexpectedly, and even recently-issued credit ratings may not fully reflect
the actual risks posed by a particular security. It is the Portfolio's policy
not to rely primarily on ratings issued by established credit rating agencies,
but to utilize such ratings in conjunction with the Adviser's own independent
and on-going review of credit quality.
 
  The Adviser attempts to be risk averse, believing that preserving principal
in periods of rising interest rates should lead to above-average returns over
the long run. The maturity structure of the Portfolio will be largely deter-
mined by the Adviser's assessment of current economic conditions and trends,
the Federal Reserve Board's management of monetary policy, fiscal policy, in-
flation expectations, government and private credit demands and global condi-
tions. Once these factors have been carefully analyzed, the average
maturity/duration of the Portfolio will be adjusted to reflect the Adviser's
outlook. Under normal market conditions, the weighted average maturity will
range between eight and twelve years, and the weighted average duration will
range between four and six years. Over a complete market cycle, the average
maturity and duration will, on average, equal the general market.
 
  Additionally, the Adviser attempts to emphasize relative values within se-
lected maturity ranges. Interest rate spreads between different quality rang-
es, by types of issues and within coupon areas are monitored, and the Portfo-
lio will be structured to take advantage of relative values within these
areas. Marketability of individual issues and diversification within the Port-
folio will be emphasized. The Portfolio will hold, under normal circumstances,
no more than 10% of its assets in any single non-governmental issue.
 
                           OTHER INVESTMENT POLICIES
 
SHORT-TERM INVESTMENTS
  In order to earn a return on uninvested assets, meet anticipated redemp-
tions, or for temporary defensive purposes, the Portfolio may invest a portion
of its assets in domestic and foreign money market instruments including cer-
tificates of deposit, bankers' acceptances, time deposits, U.S. Government ob-
ligations, U.S. Government agency securities, short-term corporate debt secu-
rities, and commercial paper rated A-1 or A-2 by S&P or Prime-1 or Prime-2 by
Moody's or if unrated, determined by the Adviser to be of comparable quality.
 
  Time deposits maturing in more than seven days will not be purchased by the
Portfolio, and time deposits maturing from two business days through seven
calen-
 
                                       5
<PAGE>
 
dar days will not exceed 15% of the total assets of the Portfolio. The Portfo-
lio will not invest in any security issued by a commercial bank unless (i) the
bank has total assets of at least $1 billion, or the equivalent in other cur-
rencies, (ii) in the case of U.S. banks, it is a member of the Federal Deposit
Insurance Corporation, and (iii) in the case of foreign branches of U.S.
banks, the security is, in the opinion of the Adviser, of an investment qual-
ity comparable with other debt securities which may be purchased by the Port-
folio.
 
  The Fund has received permission from the Securities and Exchange Commission
(the "SEC") to deposit the daily uninvested cash balances of the Fund's Port-
folios, as well as cash for investment purposes, into one or more joint ac-
counts and to invest the daily balance of the joint accounts in the following
short-term investments: fully collateralized repurchase agreements, interest-
bearing or discounted commercial paper including dollar-denominated commercial
paper of foreign issuers, and any other short-term money market instruments
including variable rate demand notes and tax-exempt money instruments. By en-
tering into these investments on a joint basis, it is expected that a Portfo-
lio may earn a higher rate of return on investments relative to what it could
earn individually.
 
  The Fund has received permission from the SEC for each of its Portfolios to
invest, for cash management purposes, the greater of 5% of its total assets or
$2.5 million in the Fund's DSI Money Market Portfolio. (See "INVESTMENT COMPA-
NIES.")

  The Portfolio may invest in repurchase agreements collateralized by U.S.
Government securities, certificates of deposit, and certain bankers' accept-
ances and other securities outlined above under "SHORT-TERM INVESTMENTS." In a
repurchase agreement, a Portfolio buys a security and simultaneously commits
to sell that security back at an agreed upon price plus an agreed upon market
rate of interest. Under a repurchase agreement, the seller is also required to
maintain the value of securities subject to the agreement at not less than
100% of the repurchase price. The value of the securities purchased will be
evaluated daily, and the Adviser will, if necessary, require the seller to
maintain additional securities to ensure that the value is in compliance with
the previous sentence.
 
  The use of repurchase agreements involves certain risks. For example, a de-
fault by the seller of the agreement may cause a Portfolio to experience a
loss or delay in the liquidation of the collateral securing the repurchase
agreement. A Portfolio might also incur disposition costs in liquidating the
collateral. While the Fund's management acknowledges these risks, it is ex-
pected that they can be controlled through stringent security selection crite-
ria and careful monitoring procedures.
 
                                       6

  The Fund has received permission from the SEC to pool daily uninvested cash
balances of the Fund's Portfolios in order to invest in repurchase agreements
on a joint basis. By entering into joint repurchase agreements, a Portfolio
may incur lower transaction costs and earn higher rates of interest on joint
repurchase agreements. The Portfolio's contribution would determine its return
from a joint repurchase agreement. (See "SHORT-TERM INVESTMENTS.")
 
LENDING OF SECURITIES
  The Portfolio may lend its investment securities to qualified institutional
investors who need to borrow securities in order to complete certain transac-
tions. The Portfolio will not loan portfolio securities to the extent that
greater than one-third of its assets at fair market value, would be committed
to loans. By lending its investment securities, the Portfolio attempts to in-
crease its income through the receipt of interest on the loan. Any gain or
loss in the market price of the securities loaned that might occur during the
term of the loan would be for the account of the Portfolio. The Portfolio may
lend its investment securities to qualified brokers, dealers, domestic and
foreign banks or other financial institutions, so long as the terms, the
structure and the aggregate amount of such loans are not inconsistent with the
Investment Company Act of 1940, as amended (the "1940 Act"). All relevant
facts and circumstances, including the creditworthiness of the broker, dealer
or institution, will be considered in making decisions with respect to the
lending of securities, subject to review by the Fund's Board of Directors.
 
  At the present time, the SEC does not object if an investment company pays
reasonable negotiated fees in connection with loaned securities so long as
such fees are set forth in a written contract and approved by the investment
company's Board of Directors. The Portfolio will continue to retain any voting
rights with respect to the loaned securities. If a material event occurs af-
fecting an investment on loan, the loan must be called and the securities vot-
ed.
 
WHEN-ISSUED, FORWARD DELIVERY AND DELAYED SETTLEMENT SECURITIES
  The Portfolio may purchase and sell securities on a "when-issued," "delayed
settlement," or "forward delivery" basis. "When-issued" or "forward delivery"
refers to securities whose terms and indenture are available, and for which a
market exists, but which are not available for immediate delivery. When-issued
and forward delivery transactions may be expected to occur a month or more be-
fore delivery is due. Delayed settlement is a term used to describe settlement
of a securities transaction in the secondary market which will occur sometime
in the future. No payment or delivery is made by the Portfolio until it re-
ceives delivery or payment from the other party to any of the above transac-
tions. It is possible that the market price of the securities at the time of
delivery may be higher or lower than the purchase price. The Portfolio will
maintain a separate account of cash or liquid securities at least equal to the
value of purchase commitments until payment
 
                                       7
<PAGE>
 
is made. Typically, no income accrues on securities purchased on a delayed de-
livery basis prior to the time delivery is made although the Portfolio may
earn income on securities it has deposited in a segregated account.
 
  The Portfolio engages in these types of purchases in order to buy securities
that fit with its investment objectives at attractive prices -- not to in-
crease its investment leverage.
 
PORTFOLIO TURNOVER
  It is expected that the annual portfolio turnover rate for the Portfolio
will not exceed 200%. In addition to Portfolio trading costs, higher rates of
portfolio turnover may result in the realization of capital gains. To the ex-
tent net short-term capital gains are realized, any distributions resulting
from such gains are considered ordinary income for federal income tax purpos-
es. (See "DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES" for more informa-
tion on taxation.) The Portfolio will not normally engage in short-term trad-
ing, but reserves the right to do so.
 
INVESTMENT COMPANIES
  The Portfolio reserves the right to invest up to 10% of its total assets,
calculated at the time of investment, in the securities of other open-end or
closed-end investment companies. No more than 5% of the Portfolio's total as-
sets may be invested in the securities of any one investment company nor may
it acquire more than 3% of the voting securities of any other investment com-
pany. The Portfolio will indirectly bear its proportionate share of any man-
agement fees paid by an investment company in which it invests in addition to
the advisory fee paid by the Portfolio.
 
  The Fund has been granted permission by the SEC to allow each of its Portfo-
lios to invest the greater of 5% of its total assets or $2.5 million in the
Fund's DSI Money Market Portfolio for cash management purposes provided that
the investment is consistent with the investing Portfolio's investment poli-
cies and restrictions. Based upon a Portfolio's assets invested in the DSI
Money Market Portfolio, an investing Portfolio's adviser will waive its in-
vestment advisory fee and any other fees earned as a result of a Portfolio's
investment in the DSI Money Market Portfolio. An investing Portfolio will bear
expenses of the DSI Money Market Portfolio on the same basis as all of its
other shareholders.
 
RESTRICTED SECURITIES
  The Portfolio may purchase restricted securities that are not registered for
sale to the general public but which are eligible for resale to qualified in-
stitutional investors under Rule 144A of the Securities Act of 1933. Under the
supervision of the Fund's Board of Directors, the Adviser determines the li-
quidity of such investments by considering all relevant factors. Provided that
a dealer or institutional trading market in such securities exists, these re-
stricted securities are not treated as
 
                                       8
<PAGE>
 
illiquid securities for purposes of the Portfolio's investment limitations.
The Portfolio may also invest up to 15% of its net assets in illiquid securi-
ties. The prices realized from the sales of these securities could be more or
less than those originally paid by the Portfolio or less than what may be con-
sidered the fair value of such securities.
 
MORTGAGE-BACKED SECURITIES
  Mortgage-backed securities are collateralized by pools of mortgages assem-
bled for subsequent sale to investors by various governmental agencies and
sponsored organizations as well as by private issuers. The underlying assets
collateralizing the mortgage-backed securities may include single-family, mul-
tifamily and commercial properties. The two fundamental forms of mortgage-
backed securities are pass-throughs and collateralized mortgage obligations
("CMOs"). Pass-throughs produce monthly payments of principal and interest
from the underlying mortgages. CMOs divide the cash flows generated from the
underlying mortgages or mortgage pass-through securities into different seg-
ments known as "tranches" which are then retired sequentially over time in or-
der of priority. The market value and yield of mortgage-backed securities will
fluctuate due to market interest rate change and early prepayments of the un-
derlying mortgages. As prepayment rates on mortgages vary widely, it is diffi-
cult to accurately predict the average maturity of a particular pool of mort-
gages or tranches of CMOs. Although mortgage-backed securities may offer
higher yields than those available from other types of securities, they may be
less effective than other types of securities as a means of "locking in" an
attractive rate for an extended period because of the prepayment feature. Pre-
payment risk has two important effects. First, like bonds in general, mort-
gage-backed securities will generally decline in price when interest rates
rise. Second, when interest rates fall and additional mortgage prepayments
must be reinvested at lower interest rates, the Portfolio's rate of dividend
income may be reduced. Mortgage-backed securities in which the Portfolio may
invest will either carry a guarantee from an agency of the U.S. Government or
a private issuer of the timely payment of principal and interest or are suit-
ably structured to be considered by the Adviser to be of investment grade
quality.
 
ASSET-BACKED SECURITIES
  Asset-backed securities are collateralized by short maturity loans such as
automobile receivables, credit card receivables, or other types of receivables
or assets, the payments from which are passed through to the security holder.
Credit support for asset-backed securities may be based on the underlying as-
sets and/or provided through credit enhancements by a third party. Credit en-
hancement techniques include letters of credit, insurance bonds, limited guar-
antees (which are generally provided by the issuer), senior-subordinated
structures and over-collateralization. The value of these securities may be
significantly affected by changes in interest rates, the market's perceptions
of the issuers and the creditworthiness of the parties involved.

YANKEE BONDS
  Yankee bonds are dollar-denominated bonds issued inside the United States by
foreign entities. Investment in these securities involve certain risks which
are not typically associated with investing in domestic securities. Non U.S.-
based issuers are not subject to the same accounting, auditing and financial
reporting standards as are domestic issuers. There may be less publicly-avail-
able information about non-U.S.-based issuers which may make it difficult to
make investment decisions. Political factors may have an impact in the form of
confiscatory taxation, expropriation or political instability in international
markets. Some foreign governments also levy withholding taxes against dividend
and interest income. Although in some countries a portion of the taxes is re-
coverable, the non-recovered portion of foreign withholding taxes will reduce
the income the Portfolio receives from the companies comprising its invest-
ments.
 
                            INVESTMENT LIMITATIONS
 
  The Portfolio will not:
  (a) with respect to 75% of its assets, invest more than 5% of its total
      assets at the time of purchase in the securities of any single issuer
      (other than obligations issued or guaranteed as to principal and in-
      terest by the U.S. Government or any agency or instrumentality there-
      of);
  (b) with respect to 75% of its assets, purchase more than 10% of any class
      of the outstanding voting securities of any issuer;
  (c) invest more than 5% of its assets at the time of purchase in the secu-
      rities of companies that have (with predecessors) a continuous operat-
      ing history of less than 3 years;
  (d) invest more than 25% of its assets in companies within a single indus-
      try; however, there are no limitations on investments made in instru-
      ments issued or guaranteed by the U.S. Government and its agencies
      when the portfolio adopts a temporary defensive position.
  (e) make loans except (i) by purchasing bonds, debentures or similar obli-
      gations which are publicly distributed, (including repurchase agree-
      ments provided, however, that repurchase agreements maturing in more
      than seven days, together with securities which are not readily mar-
      ketable, will not exceed 15% of the Portfolio's total assets), and
      (ii) by lending its portfolio securities to banks, brokers, dealers
      and other financial institutions so long as such loans are not incon-
      sistent with the 1940 Act or the Rules and Regulations or interpreta-
      tions of the SEC thereunder;
  (f) (i) borrow, except from banks and as a temporary measure for extraor-
      dinary or emergency purposes and then, in no event, in excess of 33
      1/3% of the Portfolio's gross assets valued at the lower of market or
      cost, and
 
                                      10
<PAGE>
 
      (ii) the Portfolio may not purchase additional securities when
      borrowings exceed 5% of total assets; or
  (g) pledge, mortgage or hypothecate any of its assets to an extent greater
      than 33 1/3% of its total assets at fair market value.
 
  The Portfolio's investment objective and investment limitations (a), (b),
(d), (e) and (f)(i) listed above are fundamental policies and may be changed
only with the approval of the holders of a majority of the outstanding voting
securities of the Portfolio. The other investment limitations described here
and those not specified as fundamental in the SAI as well as the Portfolio's
investment policies are not fundamental and the Fund's Board of Directors may
change them without shareholder approval.
 
                              PURCHASE OF SHARES
 
  Shares of the Portfolio are offered through UAM Fund Distributors, Inc. (the
"Distributor") without a sales commission, at the net asset value per share
next determined after an order is received by the Fund and payment is received
by the Custodian. (See "SERVICE AND DISTRIBUTION PLANS" and "VALUATION OF
SHARES.") The minimum initial investment required is $2,500. The minimum ini-
tial investment for IRA accounts is $500. The minimum initial investment for
spousal IRA accounts is $250. Certain exceptions may be made by the officers
of the Fund.
 
  The Portfolio issues two classes of shares: Institutional Class and Institu-
tional Service Class. The two classes of shares each represent interests in
the same portfolio of investments, have the same rights and are identical in
all respects, except that the Service Class Shares offered by this Prospectus
bear shareholder servicing expenses, may in the future bear distribution plan
expenses, and have exclusive voting rights with respect to the Rule 12b-1 Dis-
tribution Plan pursuant to which the distribution fee may be paid. The two
classes have different exchange privileges. (See "SHAREHOLDER SERVICES -- EX-
CHANGE PRIVILEGE.") The net income attributable to Service Class Shares and
the dividends payable on Service Class Shares will be reduced by the amount of
the shareholder servicing and distribution fees; accordingly, the net asset
value of the Service Class Shares will be reduced by such amount to the extent
the Portfolio has undistributed net income.
 
  Some Service Agents may also impose additional or different conditions or
other account fees on the purchase and redemption of Portfolio shares, which
are not subject to the Rule 12b-1 Service and Distribution Plans, which may
include transaction fees and/or service fees paid by the Fund from the Fund
assets attributable to the Service Agent and, would not be imposed if shares
of the Portfolio were purchased directly from the Fund or the Distributor. The
Service Agents may provide shareholder services to their customers that are
not available to a share-
 
                                      11
<PAGE>
 
holder dealing directly with the Fund. Each Service Agent is responsible for
transmitting to its customers a schedule of any such fees and information re-
garding any additional or different conditions regarding purchases and redemp-
tions. Shareholders who are customers of Service Agents should consult their
Service Agent for information regarding these fees and conditions. A salesper-
son and any other person entitled to receive compensation for selling or ser-
vicing Portfolio shares may receive different compensation with respect to one
particular class of shares over another in the Fund.
 
  Service Agents may enter confirmed purchase orders on behalf of their cus-
tomers. If shares of the Portfolio are purchased in this manner, the Service
Agent must receive your investment order before the close of trading on the
New York Stock Exchange ("NYSE"), and transmit it to the Fund's Sub-Transfer
Agent, Chase Global Funds Services Company, prior to the close of its business
day to receive that day's share price. Proper payment for the order must be
received by the Sub-Transfer Agent no later than the time when the Portfolio
is priced on the following business day. Service Agents are responsible to
their customers and the Fund for timely transmission of all subscription and
redemption requests, investment information, documentation and money.

Center by calling the number on the cover of this Prospectus. Mail orders
should include, when possible, the "Invest by Mail" stub which accompanies any
Fund confirmation statement.
 
OTHER PURCHASE INFORMATION
  Investments received by 4 p.m. Eastern Time (ET) (the close of the NYSE)
will be invested at the share price calculated after the NYSE closes on that
day. Investments received after the close of the NYSE will be executed at the
price computed on the next day the NYSE is open. The Fund reserves the right,
in its sole discretion, to suspend the offering of shares of the Portfolio or
to reject purchase orders when, in the judgment of management, such suspension
or rejection is in the best interests of the Fund. Purchases of a Portfolio's
shares will be made in full and fractional shares of the Portfolio calculated
to three decimal places. Certificates for fractional shares will not be is-
sued. Certificates for whole shares will not be issued except at the written
request of the shareholder.
 
IN-KIND PURCHASES
  If accepted by the Fund, shares of the Portfolio may be purchased in ex-
change for securities which are eligible for acquisition by the Portfolio, as
described in this Prospectus. Securities to be exchanged which are accepted by
the Fund will be valued as described under "VALUATION OF SHARES" at the next
determina-
 
                                      13
<PAGE>
 
tion of net asset value after acceptance. Shares issued by the Portfolio in
exchange for securities will be issued at net asset value determined as of the
same time. All dividends, interest, subscription, or other rights pertaining
to such securities shall become the property of the Portfolio and must be de-
livered to the Fund by the investor upon receipt from the issuer. Securities
acquired through an in-kind purchase will be acquired for investment and not
for immediate resale.
 
  The Fund will not accept securities in exchange for shares of the Portfolio
unless:
    . at the time of exchange, such securities are eligible to be in-
      cluded in the Portfolio (current market quotations must be readily
      available for such securities);
    . the investor represents and agrees that all securities offered to
      be exchanged are liquid securities and not subject to any restric-
      tions upon their sale by the Portfolio under the Securities Act of
      1933, or otherwise; and
    . the value of any such securities (except U.S. Government securi-
      ties) being exchanged together with other securities of the same
      issuer owned by the Portfolio will not exceed 5% of the net assets
      of the Portfolio immediately after the transaction.
 
  Investors who are subject to Federal taxation upon exchange may realize a
gain or loss for Federal income tax purposes depending upon the cost of secu-
rities or local currency exchanged. Investors interested in such exchanges
should contact the Adviser.
 
                             REDEMPTION OF SHARES
 
  Shares of the Portfolio may be redeemed by mail or telephone at any time,
without cost, at the net asset value of the Portfolio next determined after
receipt of the redemption request. No charge is made for redemptions. Any re-
demption may be more or less than the purchase price of the shares depending
on the market value of investment securities held by the Portfolio.
 
BY MAIL
  Address requests for redemption to the UAM Funds Service Center. Requests to
redeem shares must include:
    . share certificates, if issued;
    . a letter of instruction or an assignment specifying the number of
      shares or dollar amount to be redeemed, signed by all registered
      owners of the shares in the exact names in which they are regis-
      tered;
    . any required signature guarantees (see "SIGNATURE GUARANTEES"); and
 
                                      14
<PAGE>
 
    . any other necessary legal documents, if required, in the case of
      estates, trusts, guardianships, custodianships, corporations, pen-
      sion and profit sharing plans and other organizations.
 
BY TELEPHONE
  A redemption request by telephone requires the following:
    . establish the telephone redemption privilege (and if desired, the
      wire redemption privilege) by completing appropriate sections of
      the Application; and
    . call the Fund and instruct that the redemption proceeds be mailed
      to you or wired to your bank.
 
  The following tasks cannot be accomplished by telephone:
    . changing the name of the commercial bank or the account designated
      to receive redemption proceeds (this can be accomplished only by a
      written request signed by each shareholder, with each signature
      guaranteed); and
    . redemption of certificated shares by telephone.
 
  The Fund and its Sub-Transfer Agent will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine, and they may
be liable for any losses if they fail to do so. These procedures include re-
quiring the investor to provide certain personal identification at the time an
account is opened, as well as prior to effecting each transaction requested by
telephone. In addition, all telephone transaction requests will be recorded
and investors may be required to provide additional telecopied written in-
structions of such transaction requests. The Fund or Sub-Transfer Agent may be
liable for any losses due to unauthorized or fraudulent telephone instructions
if the Fund or the Sub-Transfer Agent does not employ the procedures described
above. Neither the Fund nor the Sub-Transfer Agent will be responsible for any
loss, liability, cost or expense for following instructions received by tele-
phone that it reasonably believes to be genuine.
 
SIGNATURE GUARANTEES
  Signature guarantees are required for the following redemptions:
    . redemptions where the proceeds are to be sent to someone other than
      the registered shareowner(s);
    . redemptions where the proceeds are to be sent to someplace other
      than the registered address; or
    . share transfer requests.
 
  Signature guarantees will be accepted from any eligible guarantor institu-
tion which participates in a signature guarantee program. Eligible guarantor
institutions include banks, brokers, dealers, credit unions, national securi-
ties exchanges, registered securities associations, clearing agencies and sav-
ings associations. Broker-dealers guaranteeing signatures must be a member of
a clearing corporation or
 
                                      15
<PAGE>
 
maintain net capital of at least $100,000. Credit unions must be authorized to
issue signature guarantees.
 
OTHER REDEMPTION INFORMATION
  Normally, the Fund will make payment for all shares redeemed under proper
procedures within one business day of and no more than seven days after the
receipt of the request, or earlier if required under applicable law. The Fund
may suspend the right of redemption or postpone the date at times when both
the NYSE and Custodian Bank are closed, or under any emergency circumstances
determined by the SEC.
 
  If the Board of Directors determines that it would be detrimental to the
best interests of remaining shareholders of the Fund to make payment wholly or
partly in cash, the Fund may pay redemption proceeds in whole or in part by a
distribution in-kind of liquid securities held by the Portfolio in lieu of
cash in conformity with applicable rules of the SEC. Investors may incur bro-
kerage charges on the sale of portfolio securities received in payment of re-
demptions.
 
                        SERVICE AND DISTRIBUTION PLANS
 
  Under the Service Plan for Service Class Shares, adopted pursuant to Rule
12b-1 under the 1940 Act, the Fund may enter into service agreements with
Service Agents (broker-dealers or other financial institutions) who receive
fees with respect to the Fund's Service Class Shares owned by shareholders for
whom the Service Agent is the dealer or holder of record, or for whom the
Service Agent performs Servicing, as defined below. These fees are paid out of
the assets allocable to Service Class Shares to the Distributor, to the Serv-
ice Agent directly or through the Distributor. The Fund reimburses the Dis-
tributor or the Service Agent, as the case may be, for payments made at an an-
nual rate of up to .25 of 1% of the average daily value of Service Class
Shares of the Portfolios owned by clients of such Service Agent during the pe-
riod payments for Servicing are being made to it. Such payments are borne ex-
clusively by the Service Class Shares. Each item for which a payment may be
made under the Service Plan constitutes personal service and/or shareholder
account maintenance and may constitute an expense of distributing Fund Service
Class Shares as the SEC construes such term under Rule 12b-1. The fees payable
for servicing reflect actual expenses incurred up to the limit described here-
in.
 
  Servicing may include assisting clients in changing dividend options, ac-
count designations and addresses; performing sub-accounting; establishing and
maintaining shareholder accounts and records; processing purchase and redemp-
tion transactions; investing client cash account balances automatically in
Service Class Shares; providing periodic statements showing a client's account
balance and integrating such statements with those of other transactions and
balances in the client's other
 
                                      16
<PAGE>
 
accounts serviced by the Service Agent; arranging for bank wires; and such
other services as the Fund may request, to the extent the Service Agent is
permitted by applicable statute, rule or regulation.
 
  The Glass-Steagall Act and other applicable laws prohibit Federally chart-
ered or supervised banks from engaging in certain aspects of the business of
issuing, underwriting, selling and/or distributing securities. Accordingly,
banks will be engaged to act as Service Agent only to perform administrative
and shareholder servicing functions, including transaction-related agency
services for their customers. If a bank is prohibited from acting as a trans-
fer agent, alternative means for servicing its shareholders clients would be
sought and the shareholders clients of the bank will remain Fund shareholders.
 
  The Distributor promotes the distribution of the Service Class Shares of the
Fund in accordance with the terms of a Distribution Plan adopted pursuant to
Rule 12b-1 under the 1940 Act. The Distribution Plan provides for the use of
Fund assets allocable to Service Class Shares to pay expenses of distributing
such shares.
 
  The Distribution Plan and the Service Plan (together, the "Plans") were ap-
proved by the Board of Directors, including a majority of the directors who
are not "interested persons" of the Fund as defined in the 1940 Act (and each
of whom has no direct or indirect financial interest in the Plans or any
agreement related thereto, referred to herein as the "12b-1 Directors"). The
Plans may be terminated at any time by the vote of the Board or the 12b-1 Di-
rectors, or by the vote of a majority of the outstanding voting securities of
the Service Class Shares.
 
  While the Plans continue in effect, the selection of the 12b-1 Directors is
committed to the discretion of such persons then in office. The Plans provide
generally that a Portfolio may incur distribution and service costs under the
Plans which may not exceed 0.75% per annum of that Portfolio's net assets. The
Board has currently limited payments under the Plans up to 0.50% per annum of
a Portfolio's net assets. The Service Class Shares offered by this Prospectus
currently are not making any payments under the Distribution Plan. Upon imple-
mentation, the Distribution Plan would permit payments to the Distributor,
broker-dealers, other financial institutions, sales representatives or other
third parties who render promotional and distribution services, for items such
as advertising expenses, selling expenses, commissions or travel reasonably
intended to result in sales of shares of the Service Class Shares and for the
printing of prospectuses sent to prospective purchasers of the Service Class
Shares of the Portfolios.
 
  Although the Plans may be amended by the Board of Directors, any change in
the Plans which would materially increase the amounts authorized to be paid
under the Plans must be approved by shareholders of the class involved. The
total amounts paid with respect to a class of shares of a Portfolio under the
foregoing arrangements may not exceed the maximum limits specified above, and
the
 
                                      17
<PAGE>
 
amounts and purposes of expenditures under the Plans must be reported to the
12b-1 Directors quarterly. The amounts allowable under the Plans for each
Class of Shares of the Portfolios are also limited under certain rules of the
National Association of Securities Dealers, Inc.
 
  In addition to payments by the Fund under the Plans, the Distributor, United
Asset Management Corporation ("UAM"), the parent company of the Adviser, the
Adviser, or any of their affiliates, may, at its own expense, compensate a
Service Agent or other person for marketing, shareholder servicing, record-
keeping and/or other services performed with respect to the Fund, a Portfolio
or any Class of Shares of a Portfolio. The person making such payments may do
so out of its revenues, its profits or any other source available to it. Such
service arrangements, when in effect, are made generally available to all
qualified service providers. The Adviser may compensate its affiliated compa-
nies for referring investors to the Portfolio.
 
  The Distributor, the Adviser and certain of their other affiliates also par-
ticipate, at the date of this Prospectus, in an arrangement with Smith Barney
Inc. under which Smith Barney provides certain defined contribution plan mar-
keting and shareholder services and receives from such entities an amount
equal to up to 33.3% of the portion of the investment advisory fees attribut-
able to the invested assets of Smith Barney's eligible customer accounts with-
out regard to any expense limitation in addition to amounts payable to all
selling dealers. The Fund also compensates Smith Barney for services it pro-
vides to certain defined contribution plan shareholders that are not otherwise
provided by UAMFSI.
 
                             SHAREHOLDER SERVICES
 
EXCHANGE PRIVILEGE
  Service Class Shares of the Portfolio may be exchanged for Service Class
Shares of any other UAM Funds Portfolio (See the list of Portfolios of the UAM
Funds at the end of this Prospectus.) Exchange requests should be made by con-
tacting the UAM Funds Service Center.
 
  Any exchange will be based on the net asset value of the shares involved.
There is no sales commission or charge of any kind for an exchange. Before
making an exchange into a Portfolio, a shareholder should read its Prospectus
and consider the investment objectives of the Portfolio to be purchased. Call
the UAM Funds Service Center for a copy of the Prospectus for the Portfolio(s)
in which you are interested. Exchanges can only be made with Portfolios that
are qualified for sale in a shareholder's state of residence.
 
  Exchange requests may be made either by mail or telephone. Telephone ex-
changes will be accepted only if the certificates for the shares to be ex-
changed have not been issued to the shareholder and if the registration of the
two accounts will
 
                                      18
<PAGE>
 
be identical. Requests for exchanges received prior to 4 p.m. ET will be proc-
essed as of the close of business on the same day. Requests received after 4
p.m. ET will be processed on the next business day. The Board of Directors may
limit the frequency and amount of exchanges permitted. For additional informa-
tion regarding responsibility for the authenticity of telephoned instructions,
see "REDEMPTION OF SHARES BY TELEPHONE."
 
  An exchange into another UAM Funds Portfolio is a sale of shares and may re-
sult in a gain or loss for income tax purposes. The Fund may modify or termi-
nate the exchange privilege at any time.
 
                              VALUATION OF SHARES
 
  The net asset value of the Portfolio is determined by dividing the value of
the Portfolio's assets attributable to the class, less any liabilities attrib-
utable to the class, by the number of shares outstanding attributable to the
class. The net asset value per share of the Portfolio is determined as of the
close of the NYSE on each day that the NYSE is open for business.
 
  Bonds and other fixed income securities are valued according to the broadest
and most representative market, which will ordinarily be the over-the-counter
market. Bonds and other fixed income securities may be valued on the basis of
prices provided by a pricing service when such prices are believed to reflect
the fair market value of such securities. Securities purchased with remaining
maturities of 60 days or less are valued at amortized cost when the Board of
Directors determines that amortized cost reflects fair value.
 
  The value of other assets and securities for which no quotations are readily
available (including restricted securities) is determined in good faith at
fair value using methods determined by the Directors.
 
                           PERFORMANCE CALCULATIONS
 
  The Portfolio measures performance by calculating yield and total return.
Both yield and total return figures are based on historical earnings and are
not intended to indicate future performance.
 
  Yield refers to the income generated by an investment in the Portfolio over
a given period of time, expressed as an annual percentage rate. Yields are
calculated according to a standard that is required for all funds. As this
differs from other accounting methods, the quoted yield may not equal the in-
come actually paid to shareholders.
 
  Total return is the change in value of an investment in the Portfolio over a
given period, assuming reinvestment of any dividends and capital gains. A cu-
mulative or aggregate total return reflects actual performance over a stated
period of
 
                                      19
<PAGE>
 
time. An average annual total return is a hypothetical rate of return that, if
achieved annually, would have produced the same cumulative total return if
performance had been constant over the entire period.
 
  Performance is calculated separately for Institutional Class and Service
Class Shares. Dividends paid by the Portfolio with respect to Institutional
Class and Service Class Shares, to the extent any dividends are paid, will be
calculated in the same manner at the same time on the same day and will be in
the same amount, except that service fees, distribution charges and any incre-
mental transfer agency costs relating to Service Class Shares will be borne
exclusively by that class.
 
  The Portfolio's performance may be compared to data prepared by independent
services which monitor the performance of investment companies, data reported
in financial and industry publications, and various indices as further de-
scribed in the Portfolio's SAI. This information may also be included in sales
literature and advertising.
 
  Since this is a new Portfolio, we can offer no information about past port-
folio investment performance. When this information becomes available, you
will find it, together with comparisons to appropriate indices, in the Portfo-
lio's Annual Report to Shareholders, which may be obtained without charge upon
request to the Fund by writing to the address or calling the phone number on
the cover of this Prospectus.
 
               DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES
 
DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
  The Portfolio will normally distribute substantially all of its net invest-
ment income to shareholders in quarterly dividends. If any net capital gains
are realized, the Portfolio will normally distribute them annually.
 
  All dividends and capital gains distributions will be automatically rein-
vested in additional shares of the Portfolio unless the Fund is notified in
writing that the shareholder elects to receive distributions in cash.
 
FEDERAL TAXES
  The Portfolio intends to qualify as a "regulated investment company" under
subchapter M of the Internal Revenue Code of 1986, as amended, for federal in-
come tax purposes and to meet all other requirements that are necessary for it
(but not its shareholders) to be exempt from federal taxes on income and gains
paid to shareholders in the form of dividends. To do this, the Portfolio must,
among other things, distribute substantially all of its ordinary income and
net capital gains on a current basis and maintain a portfolio of investments
which satisfies certain diversification criteria.
 
                                      20
<PAGE>
 
  Dividends paid by the Portfolio from net investment income, whether in cash
or reinvested in shares, are taxable to shareholders as ordinary income.
Short-term capital gains will be taxed as ordinary income. Long-term capital
gains distributions are taxed as long-term capital gains. Shareholders will be
notified annually of dividend income earned for tax purposes.
 
  Dividends declared in October, November and December to shareholders of rec-
ord in such a month will be treated as if they had been paid by the Fund and
received by the shareholders on December 31 of the same calendar year, pro-
vided that the dividends are paid before February of the following year.
 
  The Fund is required by Federal law to withhold 31% of reportable payments
(which may include dividends, capital gains distributions, and redemptions)
paid to shareholders who have not complied with IRS taxpayer identification
regulations. In order to avoid this withholding requirement, you must certify
that your Social Security or Taxpayer Identification Number provided is cor-
rect and that either you are not currently subject to backup withholding, or
you are exempt from backup withholding. This certification must be made on the
Application or on a separate form supplied by the Fund.
 
  Dividends and interest received by the Portfolio may give rise to withhold-
ing and other taxes imposed by foreign countries. These taxes reduce the Port-
folio's dividends but are included in the taxable income reported on your tax
statement if the Portfolio qualifies for this tax treatment and elects to pass
it through to you. Consult a tax adviser for more information regarding deduc-
tions and credits for foreign taxes.

</TABLE>
 
  The Adviser has voluntarily agreed to waive a portion of its advisory fees
and to assume as the Adviser's own expense operating expenses otherwise pay-
able by the Portfolio, if necessary, in order to reduce expense ratios. As of
the date of this Prospectus, the Adviser has agreed to keep the Bond Portfolio
Institutional Service Class Shares from exceeding 0.50%, of average daily net
assets. The Fund will not reimburse the Adviser for any advisory fees that are
waived or Portfolio expenses that the Adviser may bear on behalf of the Port-
folio for a given fiscal year.
 
  In addition, the Adviser may compensate its affiliated companies for refer-
ring investors to the Portfolio. The Distributor, UAM, the Adviser, or any of
their affiliates, may, at its own expense, compensate a Service Agent or other
person for marketing, shareholder servicing, record-keeping and/or other serv-
ices performed with respect to the Fund, a Portfolio or any Class of Shares of
a Portfolio. The person making such payments may do so out of its revenues,
its profits or any other source available to it. Such service arrangements,
when in effect, are made generally available to all qualified service provid-
ers.

                       ADVISER'S HISTORICAL PERFORMANCE
   
  Set forth below are certain performance data provided by the Adviser relat-
ing to the composite of separately managed fixed income accounts of clients of
the Adviser. These accounts have the same investment objective as the Portfo-
lio, and were managed using substantially similar, though not in all cases
identical, investment strategies, techniques and policies as those contem-
plated for use by the Adviser in managing the Portfolio. The performance data
for the managed accounts is net of all fees and expenses. The investment re-
turns of the Portfolio may differ from those of the separately managed ac-
counts because such separately managed accounts may have fees and expenses
that differ from those of the Portfolio. Further, the separately managed ac-
counts are not subject to investment limitations, diversification require-
ments, and other restrictions imposed by the 1940 Act and Internal Revenue
Code; such conditions, if applicable, may have lowered the returns for the
separately managed accounts. The results presented are not intended to predict
or suggest the return to be experienced by the Portfolio or the return an in-
vestor might achieve by investing in the Portfolio.

Notes:
1. The annualized return is calculated from monthly data, allowing for com-
   pounding. The formula used is in accordance with the acceptable methods set
   forth by the Association for Investment Management Research, the Bank Ad-
   ministration Institute, and the Investment Counsel Association of America.
   Market Value of the account was the sum of the account's total assets, in-
   cluding cash, cash equivalents, short-term investments, and securities val-
   ued at current market prices.
   
2. The cumulative return means that $1 invested in the account on 1/1/80 had
   grown to $6.83 by June 30, 1997.     
3. The 17-year mean is the arithmetic average of the annual returns for the
   calendar years listed.
4. The Lehman Brothers Aggregate Bond Index is an unmanaged index which as-
   sumes reinvestment of dividends and is generally considered representative
   of securities similar to those invested in by the Adviser for the purpose
   of the composite performance numbers set forth above.
   
5. During the period shown (1/1/80-6/30/97), fees on the Adviser's individual
   accounts ranged from 0.20% to 0.30% (20 basis points to 30 basis points).
   The Adviser's returns presented above are net of the maximum fee of 0.30%.
   Net returns to investors vary depending on the management fee.     
 
                            ADMINISTRATIVE SERVICES
 
  UAM Fund Services, Inc. ("UAMFSI"), a wholly-owned subsidiary of UAM, is re-
sponsible for performing and overseeing administrative, fund accounting, divi-
dend disbursing and transfer agent services provided to the Fund and its Port-
folios. UAMFSI's principal office is located at 211 Congress Street, Boston,
MA 02110. UAMFSI has subcontracted some of these services to Chase Global
Funds Services Company ("CGFSC"), an affiliate of The Chase Manhattan Bank, by
a Mutual Funds Service Agreement dated June 30, 1997. CGFSC is located at 73
Tremont Street, Boston, MA 02108.
 
  Each Portfolio pays UAMFSI a two part monthly fee: a Portfolio-specific fee
which is retained by UAMFSI and a sub-administration fee which UAMFSI in turn
pays to CGFSC. The Portfolio-specific fee is calculated from the aggregate net
assets of the Portfolio at the following annual rate:

                                      24
<PAGE>
 
  CGFSC's monthly fee for its services is calculated on an annualized basis as
follows:
  0.19 of 1% of the first $200 million of combined Fund assets;
  0.11 of 1% of the next $800 million of combined Fund assets;
  0.07 of 1% of combined Fund assets in excess of $1 billion but less than
  $3 billion;
  0.05 of 1% of combined Fund assets in excess of $3 billion.
 
  Fees are allocated among the Portfolios on the basis of their relative as-
sets and are subject to a graduated minimum fee schedule per Portfolio, which
starts at $2,000 per month and increases to $70,000 annually after two years.
If a separate class of shares is added to a Portfolio, its minimum annual fee
increases by $20,000.
 
                                  DISTRIBUTOR
 
  UAM Fund Distributors, Inc., a wholly-owned subsidiary of UAM, with its
principal office located at 211 Congress Street, Boston, MA 02110, distributes
the shares of the Fund. Under the Fund's Distribution Agreement (the "Agree-
ment"), the Distributor, as agent of the Fund, agrees to use its best efforts
as sole distributor of the Fund's shares. The Distributor does not receive any
fee or other compensation under the Agreement (except as described under
"SERVICE AND DISTRIBUTION PLANS" above). The Agreement continues in effect so
long as such continuance is approved at least annually by the Fund's Board of
Directors, including a majority of those Directors who are not parties to such
Agreement or interested persons of any such party. The Agreement provides that
the Fund will bear the costs of the registration of its shares with the SEC
and various states and the printing of its prospectuses, SAIs and reports to
shareholders.
 
                            PORTFOLIO TRANSACTIONS
 
  The Advisory Agreements for the Fund's Portfolios authorize the Adviser to
select the brokers or dealers that will execute the purchases and sales of in-
vestment securities for each Portfolio. The Agreements direct the Adviser to
use its best efforts to obtain the best available price and most favorable ex-
ecution for all transactions of the Portfolios. If consistent with the inter-
ests of the Portfolios, the Adviser may select brokers on the basis of the re-
search, statistical and pricing services they provide to the Portfolios. Such
brokers may be paid a higher commission than that which another qualified bro-
ker would have charged for effecting the same transaction, provided that such
commissions are paid in compliance with the Securities Exchange Act of 1934,
as amended, and that the Adviser determines in good faith that such commission
is reasonable in terms either of the transaction or the overall responsibility
of the Adviser to the Portfolios and the Adviser's other clients.
 
                                      25
<PAGE>
 
  Although not a typical practice, the Adviser may place portfolio orders with
qualified broker-dealers who refer clients to the Adviser.
 
  If a purchase or sale of securities is consistent with the investment poli-
cies of a Portfolio and one or more of these other clients served by the Ad-
viser is considering a purchase at or about the same time, transactions in
such securities will be allocated among the Portfolio and clients in a manner
deemed fair and reasonable by the Adviser. Although there is no specified for-
mula for allocating such transactions, such allocations are subject to peri-
odic review by the Fund's Directors.
 
                              GENERAL INFORMATION
 
DESCRIPTION OF SHARES AND VOTING RIGHTS
  The Fund was organized under the name "ICM Fund, Inc." as a Maryland corpo-
ration on October 11, 1988. On January 18, 1989, the name of the Fund was
changed to "The Regis Fund, Inc." On October 31, 1995, the name of the Fund
was changed to "UAM Funds, Inc."
 
  The Fund's Articles of Incorporation, as amended, permit the Directors to
issue three billion shares of common stock, with an $.001 par value. The Di-
rectors have the power to designate one or more series or classes of shares of
common stock and to classify or reclassify any unissued shares without further
action by shareholders. At its discretion, the Board of Directors of the Fund
may create additional Portfolios and classes of shares.
 
  The shares of each Portfolio are fully paid and nonassessable, and have no
preference as to conversion, exchange, dividends, retirement or other features
and have no pre-emptive rights. They have non-cumulative voting rights, which
means that the holders of more than 50% of the shares voting for the election
of Directors can elect 100% of the Directors. A shareholder is entitled to one
vote for each full share held (and a fractional vote for each fractional share
held), then standing in his name on the books of the Fund.
 
  The persons or organizations owning 25% or more of the outstanding shares of
a Portfolio may be presumed to "control" (as that term is defined in the 1940
Act) such Portfolio. As a result, those persons or organizations could have
the ability to vote a majority of the shares of the Portfolio on any matter
requiring the approval of shareholders of the Portfolio. Both Institutional
Class and Institutional Service Class Shares represent an interest in the same
assets of the Portfolio. Service Class Shares bear certain expenses related to
shareholder servicing, may bear expenses related to the distribution of such
shares and have exclusive voting rights with respect to matters relating to
such distribution expenditures. For information about the Institutional Class
Shares of the Portfolios contact the UAM Funds Service Center.

  Annual meetings will not be held except as required by the 1940 Act and
other applicable laws. The Fund has undertaken that its Directors will call a

ers of not less than 10% of the outstanding shares of the Fund. The Fund will
assist shareholder communications in such matters to the extent required by
the undertaking.

                       INVESTMENT OBJECTIVE AND POLICIES

  The following policies supplement the investment objective and policies of the
Sirach Bond Portfolio (the "Portfolio") as set forth in the Portfolio's
Prospectuses:

LENDING OF SECURITIES

  The Portfolio may lend its investment securities to qualified brokers,
dealers, domestic and foreign banks or other financial institutions, so long as
the terms, the structure and the aggregate amount of such loans are not
inconsistent with the Investment Company Act of 1940, as amended, (the "1940
Act") or the Rules and Regulations or interpretations of the Securities and
Exchange Commission (the "SEC") thereunder, which currently require that (a)
the borrower pledge and maintain with the Portfolio collateral consisting of
cash, an irrevocable letter of credit issued by a domestic U.S. bank or
securities issued or guaranteed by the United States Government having a value
at all times not less than 100% of the value of the securities loaned, (b) the
borrower add to such collateral whenever the price of the securities loaned
rises (i.e., the borrower "marks to the market" on a daily basis), (c) the
loan be made subject to termination by the Portfolio at any time, and (d) the
Portfolio receives reasonable interest on the loan (which may include the
Portfolio investing any cash collateral in interest bearing short-term
investments). As with other extensions of credit, there are risks of delay in
recovery or even loss of rights in the securities loaned if the borrower of the
securities fails financially. These risks are similar to the ones involved with
repurchase agreements as discussed in the Prospectus.

SHORT-TERM INVESTMENTS

  The Portfolio may invest in time deposits, certificates of deposit (including
marketable variable rate certificates of deposit) and bankers' acceptances
issued by a commercial bank or savings and loan association. Time deposits are
non-negotiable deposits maintained in a banking institution for a specified
period of time at a stated interest rate. Time deposits maturing in more than
seven days will not be purchased by the Portfolio, and time deposits maturing
from two business days through seven calendar days will not exceed 15% of the
total assets of the Portfolio.

  Certificates of deposit are negotiable short-term obligations issued by
commercial banks or savings and loan associations collateralized by funds
deposited in the issuing institution. Variable rate certificates of deposit are
certificates of deposit on which the interest rate is periodically adjusted
prior to their stated maturity based upon a specified market rate. A bankers'
acceptance is a time draft drawn on a commercial bank by a borrower, usually in
connection with an international commercial transaction (to finance the import,
export, transfer or storage of goods).

                       PURCHASE AND REDEMPTION OF SHARES

  Both classes of shares of the Portfolio may be purchased without a sales
commission at the Net Asset Value per Share (NAV) next determined after an order
is received in proper form by the Fund and payment is received by the Fund's
Custodian.  An order received in proper form prior to the 4:00 p.m. close of the
New York Stock Exchange ("Exchange") will be executed at the price computed on
the date of receipt; and an order received not in proper form or after the 4:00
p.m. close of the Exchange will be executed at the price computed on the next
day the Exchange is open after proper receipt. The Exchange will be closed on
the following days: Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day, Christmas Day and
New Year's Day.

  The Portfolio reserves the right in its sole discretion (1) to suspend the
offering of its shares, (2) to reject purchase orders when in the judgment of
management such rejection is in the best interest of the Fund, and (3) to reduce
or waive the minimum for initial and subsequent investment for certain fiduciary
accounts such as employee benefit plans or under circumstances where certain
economies can be achieved in sales of a Portfolio's shares.

  The Portfolio may suspend redemption privileges or postpone the date of
payment (1) during any period that both the Exchange and custodian bank are
closed or trading on the Exchange is restricted as determined by the SEC. (2)
during any period when an emergency exists as defined by the rules of the SEC as
a result of which it is not reasonably practicable for a Portfolio to dispose of
securities owned by it or to fairly determine the value of its 

                                       2
<PAGE>
 
assets, and (3) for such other periods as the SEC may permit. The Fund has made
an election with the SEC to pay in cash all redemptions requested by any
shareholder of record limited in amount during any 90-day period to the lesser
of $250,000 or 1% of the net assets of the Fund at the beginning of such period.
Such commitment is irrevocable without the prior approval of the SEC.
Redemptions in excess of the above limits may be paid, in whole or in part, in
investment securities or in cash as the Directors may deem advisable; however,
payment will be made wholly in cash unless the Directors believe that economic
or market conditions exist which would make such a practice detrimental to the
best interests of the Fund. If redemptions are paid in investment securities,
such securities will be valued as set forth in the Prospectus under "Valuation
of Shares" and a redeeming shareholder would normally incur brokerage expenses
if these securities were converted to cash.

  No charge is made by the Portfolio for redemptions. Any redemption may be more
or less than the shareholder's initial cost depending on the market value of the
securities held by the Portfolio.

SIGNATURE GUARANTEES

  To protect your account, the Fund and Chase Global Funds Services Company
("CGFSC") from fraud, signature guarantees are required for (1) redemptions
where the proceeds are to be sent to someone other than the registered
shareowner(s) or registered address or (2) share transfer requests.

  Signatures must be guaranteed by an "eligible guarantor institution" as
defined in Rule 17Ad-15 under the Securities Exchange Act of 1934, and as
further described in the Portfolio's Prospectuses.  The signature guarantee must
appear either: (1) on the written request for redemption; (2) on a separate
instrument for assignment ("stock power") which should specify the total
number of shares to be redeemed; or (3) on all stock certificates tendered for
redemption and, if shares held by the Fund are also being redeemed, on the
letter or stock power.

                             SHAREHOLDER SERVICES

EXCHANGE PRIVILEGE

  Exchange requests should be made by calling the Fund (1-800-638-7983) or by
writing to UAM Funds, UAM Funds Service Center, c/o Chase Global Funds Services
Company, P.O. Box 2798, Boston, MA 02208-2798. The exchange privilege is only
available with respect to Portfolios that are qualified for sale in a
shareholder's state of residence.  Any such exchange will be based on the
respective NAVs of the shares involved. There is no sales commission or charge
of any kind. Before making an exchange into a Portfolio, a shareholder should
read its Prospectus and consider the investment objectives of the Portfolio to
be purchased. You may obtain a Prospectus for the Portfolio(s) you are
interested in by calling the UAM Funds Service Center at 1-800-638-7983.

  Neither the Fund nor CGFSC will be responsible for the authenticity of the
exchange instructions received by telephone. Exchanges may also be subject to
limitations as to amounts or frequency and to other restrictions established by
the Board of Directors to assure that such exchanges do not disadvantage the
Fund and its shareholders.

  For Federal income tax purposes an exchange between Portfolios is a taxable
event, and, accordingly, a capital gain or loss may be realized. In a revenue
ruling relating to circumstances similar to the Fund's, an exchange between
series of a Fund was also deemed to be a taxable event. It is likely, therefore,
that a capital gain or loss would be realized on an exchange between Portfolios;
you may want to consult your tax adviser for further information in this regard.
The exchange privilege may be modified or terminated at any time.

TRANSFER OF SHARES

  Shareholders may transfer shares to another person by making a written request
to the Fund. The request should clearly identify the account and number of
shares to be transferred, and include the signature of all registered owners and
all stock certificates, if any, which are subject to the transfer. The signature
on the letter of request, the stock certificate or any stock power must be
guaranteed in the same manner as described under "Purchase and 

                                       3
<PAGE>
 
Redemption of Shares." As in the case of redemptions, the written request must
be received in good order before any transfer can be made.

                            INVESTMENT LIMITATIONS

  The following limitations supplement those set forth in the Prospectuses.
Whenever an investment limitation sets forth a percentage limitation on
investment or utilization of assets, such limitation shall be determined
immediately after and as a result of a Portfolio's acquisition of such security
or other asset. Accordingly, any later increase or decrease resulting from a
change in values, net assets or other circumstances will not be considered when
determining whether the investment complies with the Portfolio's investment
limitations.  The Portfolio's following fundamental investment limitations
cannot be changed without approval by a "majority of the outstanding shares" (as
defined in the 1940 Act) of the Portfolio.  The Portfolio will not:

  (1) invest in physical commodities or contracts on physical commodities;

  (2) purchase or sell real estate or real estate limited partnerships, although
      it may purchase or sell securities of companies which deal in real estate
      and may purchase and sell securities which are secured by interests in
      real estate;

  (3) with respect to 75% of its assets, purchase more than 10% of any class of
      the outstanding voting securities of any issuer;

  (4) with respect to 75% of its assets, invest more than 5% of its total assets
      at the time of purchase in securities of any single issuer (other than
      obligations issued or guaranteed as to principal and interest by the
      government of the U.S. or any agency or instrumentality thereof);

  (5) borrow money, except (i) from banks and as a temporary measure for
      extraordinary or emergency purposes or (ii) except in connection with
      reverse repurchase agreements provided that (i) and (ii) in combination do
      not exceed 33 1/3% of the Portfolio's total assets (including the
      amount borrowed) less liabilities (exclusive of borrowings);

  (6) acquire any securities of companies within one industry if, as a result of
      such acquisition, more than 25% of the value of the Portfolio's total
      assets would be invested in securities of companies within such industry;
      provided, however, that there shall be no limitation on the purchase of
      obligations issued or guaranteed by the U.S. Government, its agencies or
      instrumentalities or instruments issued by U.S. banks when the Portfolio
      adopts a temporary defensive position;

  (7) make loans except (i) by purchasing debt securities in accordance with its
      investment objectives and policies, or entering into repurchase
      agreements, subject to the limitation described in (d) below and (ii) by
      lending its portfolio securities to banks, brokers, dealers and other
      financial institutions so long as such loans are not inconsistent with the
      1940 Act or the rules and regulations or interpretations of the SEC
      thereunder; and

  (8) underwrite the securities of other issuers;

  (9) issue senior securities, as defined in the 1940 Act, except that this
      restriction shall not be deemed to prohibit the Portfolio from (i) making
      any permitted borrowings, mortgages or pledges, or (ii) entering into
      repurchase transactions;

  The following limitations are non-fundamental policies of the Portfolio.  The
Portfolio will not:

  (a) purchase on margin or sell short;

  (b) purchase or retain securities of an issuer if those officers and Directors
      of the Fund or its investment advisor owning more than  1/2 of 1% of such
      securities together own more than 5% of such securities;

                                       4
<PAGE>
 
  (c) pledge, mortgage, or hypothecate any of its assets to an extent greater
      than 33% of its total assets at fair market value;

  (d) invest more than an aggregate of 15% of the net assets of the Portfolio
      determined at the time of investment, in securities subject to legal or
      contractual restrictions on resale or securities for which there are no
      readily available markets, including repurchase agreements having
      maturities of more than seven days; and

  (e) invest for the purpose of exercising control over management of any
      company.

                              INVESTMENT ADVISER

CONTROL OF ADVISER

  Sirach Capital Management, Inc. (the "Adviser") is a wholly-owned subsidiary
of UAM, a holding company incorporated in Delaware in December 1980 for the
purpose of acquiring and owning firms engaged primarily in institutional
investment management. Since its first acquisition in August 1983, UAM has
acquired or organized approximately 47 such wholly-owned affiliated firms (the
"UAM Affiliated Firms"). UAM believes that permitting UAM Affiliated Firms to
retain control over their investment advisory decisions is necessary to allow
them to continue to provide investment management services that are intended to
meet the particular needs of their respective clients. Accordingly, after
acquisition by UAM, UAM Affiliated Firms continue to operate under their own
firm name, with their own leadership and individual investment philosophy and
approach. Each UAM 

                                       6
<PAGE>
 
Affiliated Firm manages its own business independently on a day-to-day basis.
Investment strategies employed and securities selected by UAM Affiliated Firms
are separately chosen by each of them.

PHILOSOPHY AND STYLE

  The Adviser specializes in identifying and investing in growth-oriented
securities which have demonstrated strong earnings acceleration and what the
Adviser judges to be strong relative price strength and value. The Adviser
emphasizes disciplined security selection in all asset classes.

  In managing fixed income portfolios, the Adviser regularly assesses monetary
policy, inflation expectations, economic trends and capital market flows and
then establishes a duration target and maturity structure. Sector weightings are
determined by business cycle analysis, relative valuation and expected interest
rate volatility. The Adviser also screens for mispriced securities emphasizing
both incremental yield and potential price performance. Before any security is
purchased, a thorough credit and fundamental analysis is done.

REPRESENTATIVE INSTITUTIONAL CLIENTS

  As of the date of this Statement of Additional Information, the Adviser's
representative institutional clients included: Boeing, Honda of America, City of
Seattle and United Technologies.

  In compiling this client list, the Adviser used objective criteria such as
account size, geographic location and client classification. The Adviser did not
use any performance based criteria. It is not known whether these clients
approve or disapprove of the Adviser or the advisory services provided.

ADVISORY FEES

  As compensation for services rendered by the Adviser under the Portfolio's
Investment Advisory Agreement, the Portfolio pays the Adviser an annual fee, in
monthly installments, calculated by applying the following annual percentage
rate to the Portfolio's average daily net assets for the month:

  Sirach Bond Portfolio.............................................0.35%

                        SERVICE AND DISTRIBUTION PLANS

  As stated in the Portfolio's Service Class Shares Prospectus, the Distributor
may enter into agreements with broker-dealers and other financial institutions
("Service Agents"), pursuant to which they will provide administrative support
services to Service Class shareholders who are their customers ("Customers")
in consideration of the Fund's payment of 0.25 of 1% (on an annualized basis) of
the average daily NAV of the Service Class Shares held by the Service Agent for
the benefit of its Customers. Such services include: (a) acting as the sole
shareholder of record and nominee for beneficial owners; (b) maintaining account
record for such beneficial owners of the Fund's shares; (c) opening and closing
accounts; (d) answering questions and handling correspondence from shareholders
about their accounts; (e) processing shareholder orders to purchase, redeem and
exchange shares; (f) handling the transmission of funds representing the
purchase price or redemption proceeds; (g) issuing confirmations for
transactions in the Fund's shares by shareholders; (h) distributing current
copies of prospectuses, statements of additional information and shareholder
reports; (i) assisting customers in completing application forms, selecting
dividend and other account options and opening any necessary custody accounts;
(j) providing account maintenance and accounting support for all transactions;
and (k) performing such additional shareholder services as may be agreed upon by
the Fund and the Service Agent, provided that any such additional shareholder
service must constitute a permissible non-banking activity in accordance with
the then current regulations of, and interpretations thereof by, the Board of
Governors of the Federal Reserve System, if applicable.

  Each agreement with a Service Agent is governed by a Shareholder Service Plan
(the "Service Plan") that has been adopted by the Fund's Board of Directors.
Pursuant to the Service Plan, the Board of Directors reviews, at least
quarterly, a written report of the amounts expended under each agreement with
Service Agents and the purposes for which the expenditures were made. In
addition, arrangements with Service Agents must be approved annually by a

                                       7
<PAGE>
 
majority of the Fund's Directors, including a majority of the Directors who are
not "interested persons" of the company as defined in the 1940 Act and have no
direct or indirect financial interest in such arrangements.

  The Board of Directors has approved the arrangements with Service Agents based
on information provided by the Fund's service contractors that there is a
reasonable likelihood that the arrangements will benefit the Fund and its
shareholders by affording the Fund greater flexibility in connection with the
servicing of the accounts of the beneficial owners of its shares in an efficient
manner. Any material amendment to the Fund's arrangements with Service Agents
must be approved by a majority of the Fund's Board of Directors (including a
majority of the disinterested Directors). So long as the arrangements with
Service Agents are in effect, the selection and nomination of the members of the
Fund's Board of Directors who are not "interested persons" (as defined in the
1940 Act) of the Company will be committed to the discretion of such non-
interested Directors.

  Pursuant to Rule 12b-1 under the 1940 Act, the Fund has adopted a Distribution
Plan for the Service Class Shares of the Fund (the "Distribution Plan"). The
Distribution Plan permits the Fund to pay for certain distribution, promotional
and related expenses involved in the marketing of only the Service Class Shares.

  The Distribution Plan permits the Service Class Shares, pursuant to the
Distribution Agreement, to pay a monthly fee to the Distributor for its services
and expenses in distributing and promoting sales of the Service Class Shares.
These expenses include, among other things, preparing and distributing
advertisements, sales literature and prospectuses and reports used for sales
purposes, compensating sales and marketing personnel, and paying distribution
and maintenance fees to securities brokers and dealers who enter into agreements
with the Distributor. In addition, the Service Class Shares may make payments
directly to other unaffiliated parties, who either aid in the distribution of
their shares or provide services to the Class.

  The maximum annual aggregate fee payable by the Fund under the Service and
Distribution Plans (the "Plans"), is 0.75% of the Service Class Shares'
average daily net assets for the year. The Fund's Board of Directors may reduce
this amount at any time. Although the maximum fee payable under the 12b-1 Plan
relating to the Service Class Shares is 0.75% of average daily net assets of
such Class, the Board of Directors has determined that the annual fee, payable
on a monthly basis, under the Plans relating to the Service Class Shares,
currently cannot exceed 0.50% of the average daily net assets represented by the
Service Class. While the current fee which will be payable under the Service
Plan has been set at 0.25%, the Plan permits a full 0.75% on all assets to be
paid at any time following appropriate Board approval.

  All of the distribution expenses incurred by the Distributor and others, such
as broker/dealers, in excess of the amount paid by the Service Class Shares will
be borne by such persons without any reimbursement from such classes. Subject to
seeking best price and execution, the Fund may, from time to time, buy or sell
portfolio securities from or to firms which receive payments under the Plans.
From time to time, the Distributor may pay additional amounts from its own
resources to dealers for aid in distribution or for aid in providing
administrative services to shareholders.

  The Plans, the Distribution Agreement and the form of dealer's and services
agreements have all been approved by the Board of Directors of the Fund,
including a majority of the Directors who are not "interested persons" (as
defined in the 1940 Act) of the Fund and who have no direct or indirect
financial interest in the Plans or any related agreements, by vote cast in
person at a meeting duly called for the purpose of voting on the Plans and such
Agreements. Continuation of the Plans, the Distribution Agreement and the
related agreements must be approved annually by the Board of Directors in the
same manner, as specified above.

  Each year the Directors must determine whether continuation of the Plans is in
the best interest of the shareholders of Service Class Shares and that there is
a reasonable likelihood of the Plans providing a benefit to the Class. The
Plans, the Distribution Agreement and the related agreements with any broker-
dealer or others relating to a Class may be terminated at any time without
penalty by a majority of those Directors who are not "interested persons" or
by a majority vote of the outstanding voting securities of the Class. Any
amendment materially increasing the maximum percentage payable under the Plans
must likewise be approved by a majority vote of the relevant Class' outstanding
voting securities, as well as by a majority vote of those Directors who are not
"interested persons." Also, any other material amendment to the Plans must be
approved by a majority vote of the Directors 

                                       8
<PAGE>
 
including a majority of the Directors of the Fund having no interest in the
Plans. In addition, in order for the Plans to remain effective, the selection
and nomination of Directors who are not "interested persons" of the Fund must be
effected by the Directors who themselves are not "interested persons" and who
have no direct or indirect financial interest in the Plans. Persons authorized
to make payments under the Plans must provide written reports at least quarterly
to the Board of Directors for their review. The NASD has adopted amendments to
its Conduct Rules relating to investment company sales charges. The Fund and the
Distributor intend to operate in compliance with these rules.

                            PORTFOLIO TRANSACTIONS

  The Investment Advisory Agreement authorizes the Adviser to select the brokers
or dealers that will execute the purchases and sales of investment securities
for the Portfolio and direct the Adviser to use its best efforts to obtain the
best execution with respect to all transactions for the Portfolio. In doing so,
the Portfolio may pay higher commission rates than the lowest rate available
when the Adviser believes it is reasonable to do so in light of the value of the
research, statistical, and pricing services provided by the broker effecting the
transaction. It is not the Fund's practice to allocate brokerage or effect
principal transactions with dealers on the basis of sales of shares which may be
made through broker-dealer firms. However, the Adviser may place portfolio
orders with qualified broker-dealers who recommend the Fund's Portfolios or who
act as agents in the purchase of shares of the Portfolios for their clients.
During the fiscal years ended, October 31, 1994, 1995 and 1996, the entire Fund
paid brokerage commissions of approximately $2,402,000, $2,983,000 and
$2,887,884, respectively.

  Some securities considered for investment by the Portfolio may also be
appropriate for other clients served by the Adviser. If purchases or sales of
securities consistent with the investment policies of the Portfolio and one or
more of these other clients served by the Adviser is considered at or about the
same time, transactions in such securities will be allocated among the Portfolio
and clients in a manner deemed fair and reasonable by the Adviser. Although
there is no specified formula for allocating such transactions, the various
allocation methods used by the Adviser, and the results of such allocations, are
subject to periodic review by the Fund's Directors.

                            ADMINISTRATIVE SERVICES

  As stated in the Prospectuses, the Board of Directors of the Fund approved a
new Fund Administration Agreement between UAM Funds Services, Inc., a wholly
owned subsidiary of UAM, and the Fund. The Fund's Directors also approved a
Mutual Fund Services Agreement between FSI and CGFSC.  The services provided by
FSI and CGFSC and the basis of the fees payable by the Fund under the Fund
Administration Agreement are described in the Portfolio's Prospectuses. Prior to
April 15, 1996, CGFSC or its predecessor, Mutual Funds Service Company, provided
certain administrative services to the Fund under an Administration Agreement
between the Fund and U.S. Trust Company of New York. The basis of the fees paid
to CGFSC for the most recent fiscal period to April 14, 1996 was as follows: the
Fund paid a monthly fee for its services which on an annualized basis equaled
0.20% of the first $200 million in combined assets; plus 0.12% of the next $800
million in combined assets; plus 0.08% on assets over $1 billion but less than
$3 billion; plus 0.06% on assets over $3 billion. The fees were allocated among
the Portfolios on the basis of their relative assets and were subject to a
designated minimum fee schedule per Portfolio, which ranged from $2,000 per
month upon inception of a Portfolio to $70,000 annually after two years.

                           PERFORMANCE CALCULATIONS

PERFORMANCE

  The Fund may from time to time quote various performance figures to illustrate
past performance of each class of the Fund's Portfolios.

  Performance quotations by investment companies are subject to rules adopted by
the SEC, which require the use of standardized performance quotations or,
alternatively, that every non-standardized performance quotation furnished by
each class of the Fund be accompanied by certain standardized performance
information computed as required by the SEC. Total return quotations used by
each class of the Fund are based on the standardized methods 

                                       9
<PAGE>
 
of computing performance mandated by the SEC. An explanation of those and other
methods used by each class of the Fund to compute or express performance
follows.

TOTAL RETURN

  The average annual total return is determined by finding the average annual
compounded rates of return over 1, 5, and 10 year periods that would equate an
initial hypothetical $1,000 investment to its ending redeemable value. The
calculation assumes that all dividends and distributions are reinvested when
paid. The quotation assumes the amount was completely redeemed at the end of
each 1, 5 and 10 year period and the deduction of all applicable Fund expenses
on an annual basis. Since Service Class Shares of the Portfolio bear additional
service and distribution expenses, the average annual total return of the
Service Class Shares of the Portfolio will generally be lower than that of the
Institutional Class Shares of the Portfolio.

  Total Return is calculated according to the following formula:

  P(1 + T)/n/= ERV

  where:

  P=   a hypothetical initial payment of $1,000
  T=   average annual total returnn
  n=   number of years
  ERV= ending redeemable value of a hypothetical $1,000 payment made at the
       beginning of the 1, 5, or 10 year periods at the end of the 1, 5, or 10
       year periods (or fractional portion thereof).

  Shares of the Portfolio have not been offered for sale as of the date of this
SAI.  Accordingly, no total return figures are available.

YIELD
- -----

  Current yield reflects the income per share earned by a Portfolio's
investments. The current yield of the Portfolio is determined by dividing the
net investment income per share earned during a 30-day base period by the
maximum offering price per share on the last day of the period and annualizing
the result. Expenses accrued for the period include any fees charged to all
shareholders during the base period.  Since Service Class Shares of the
Portfolio bear additional service and distribution expenses, the yield of the
Service Class Shares of the Portfolio will generally be lower than that of the
Institutional Class Shares of the Portfolio.

  Yield is obtained using the following formula:

  Yield = 2[(a - b  + 1)/6/ - 1]
            ------              
              cd

where:

  a=   dividends and interest earned during the period
  b=   expenses accrued for the period (net of reimbursements)
  c=   the average daily number of shares outstanding during the period that 
       were entitled to receive income distributions
  d=   the maximum offering price per share on the last day of the period.

  Shares of the Portfolio have not been offered for sale as of the date of this
SAI.  Accordingly, no yield figures are available.

COMPARISONS

  To help investors better evaluate how an investment in a Portfolio of the Fund
might satisfy their investment objective, advertisements regarding the Fund may
discuss various measures of Fund performance as reported by various financial
publications. Advertisements may also compare performance (as calculated above)
to performance as reported by other investments, indices and averages.  Please
see Appendix B for publications, indices and averages which may be used.

  In assessing such comparisons of performance, an investor should keep in mind
that the composition of the investments in the reported indices and averages is
not identical to the composition of investments in the Fund's Portfolios, that
the averages are generally unmanaged, and that the items included in the
calculations of such averages may not be identical to the formula used by a
Portfolio to calculate its performance. In addition, there can be no assurance
that a Portfolio will continue this performance as compared to such other
averages.

                              GENERAL INFORMATION

DESCRIPTION OF SHARES AND VOTING RIGHTS

  The Fund was organized under the name "ICM Fund, Inc." as a Maryland
corporation on October 11, 1988. On January 18, 1989, the name of the Fund was
changed to "The Regis Fund, Inc." On October 31, 1995, the name of the Fund
was changed to UAM Funds, Inc. The Fund's principal executive office is located
at One International Place, Boston, MA 02110; however, all investor
correspondence should be directed to the Fund at the UAM Funds Service Center,
c/o Chase Global Funds Services Company, P.O. Box 2798, Boston, MA 02208-2798.
The Fund's Articles of Incorporation, as amended, authorize the Directors to
issue 3,000,000,000 shares of common stock, $.001 par value. The Board of
Directors has the power to designate one or more series (Portfolios) or classes
of common stock and to classify or reclassify any unissued shares with respect
to such Portfolios, without further action by shareholders. The Directors of the
Fund may create additional Portfolios and classes of shares at a future date.

  Both classes of shares of each Portfolio of the Fund, when issued and paid for
as provided for in the Prospectuses, will be fully paid and nonassessable, have
no preference as to conversion, exchange, dividends, retirement or other
features and have no preemptive rights. The shares of the Fund have
noncumulative voting rights, which means that the holders of more than 50% of
the shares voting for the election of Directors can elect 100% of the Directors
if they choose to do so. A shareholder is entitled to one vote for each full
share held (and a fractional vote for each fractional share held), then standing
in his or her name on the books of the Fund. Both Institutional Class and
Service Class Shares represent an interest in the same assets of a Portfolio and
are identical in all respects except that the Service Class Shares bear certain
expenses related to shareholder servicing and the distribution of such shares
and have exclusive voting rights with respect to matters relating to such
distribution expenditures.

DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS

  The Fund's policy is to distribute substantially all of a Portfolio's net
investment income, if any, together with any net realized capital gains in the
amount and at the times that will avoid both income (including capital gains)
taxes on it and the imposition of the Federal excise tax on undistributed income
and capital gains (see discussion under "Dividends, Capital Gains Distributions
and Taxes" in the Prospectuses). The amounts of any income dividends or capital
gains distributions cannot be predicted.

  Any dividend or distribution paid shortly after the purchase of shares of a
Portfolio by an investor may have the effect of reducing the NAV of the
Portfolio by the per share amount of the dividend or distribution. Furthermore,
such dividends or distributions, although in effect a return of capital, are
subject to income taxes as set forth in the Prospectuses.

  As set forth in the Prospectuses, unless the shareholder elects otherwise in
writing, all dividend and capital gains distributions are automatically received
in additional shares of a Portfolio at net asset value (as of the business 

                                       11
<PAGE>
 
day following the record date). This will remain in effect until the Fund is
notified by the shareholder in writing at least three days prior to the record
date that either the Income Option (income dividends in cash and capital gains
distributions in additional shares at net asset value) or the Cash Option (both
income dividends and capital gains distributions in cash) has been elected. An
account statement is sent to shareholders whenever an income dividend or capital
gains distribution is paid.

  Each Portfolio will be treated as a separate entity (and hence as a separate
"regulated investment company") for Federal tax purposes. Any net capital
gains recognized by a Portfolio will be distributed to its investors without
need to offset (for Federal income tax purposes) such gains against any net
capital losses of another Portfolio.

FEDERAL TAXES

  In order for a Portfolio to continue to qualify for Federal income tax
treatment as a regulated investment company under the Internal Revenue Code of
1986, as amended (the "Code"), at least 90% of its gross income for a taxable
year must be derived from qualifying income; i.e., dividends, interest, income
derived from loans of securities, and gains from the sale of securities or
foreign currencies, or other income derived with respect to its business of
investing in such securities or currencies. In addition, gains realized on the
sale or other disposition of securities held for less than three months must be
limited to less than 30% of a Portfolio's annual gross income.

  Each Portfolio will distribute to shareholders annually any net capital gains
which have been recognized for Federal income tax purposes. Shareholders will be
advised on the nature of the payments.

CODE OF ETHICS

  The Fund has adopted a Code of Ethics which restricts to a certain extent
personal transactions by access persons of the Fund and imposes certain
disclosure and reporting obligations.

              APPENDIX A -- DESCRIPTION OF SECURITIES AND RATINGS

I. DESCRIPTION OF CORPORATE BOND RATINGS

Moody's Investors Service, Inc. Corporate Bond Ratings:

        Aaa - Bonds which are rated Aaa are judged to be the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt-edge." Interest payments are protected by a large or by an exceptionally
stable margin, and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues.

        Aa - Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.

        Moody's applies numerical modifiers 1, 2 and 3 in the Aa and A rating
categories. The modifier 1 indicates that the security ranks at a higher end of
the rating category, modifier 2 indicates a mid-range rating and the modifier 3
indicates that the issue ranks at the lower end of the rating category.

        A - Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.

        Baa - Bonds which are rated Baa are considered as medium grade
obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

        Ba - Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate, and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.

        B - Bonds which are rated B generally lack characteristics of the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.

        Caa - Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.

        Ca - Bonds which are rated Ca represent obligations which are
speculative in a high degree. Such issues are often in default or have other
marked shortcomings.

        C - Bonds which are rated C are the lowest rated class of bonds, and
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing.

Standard & Poor's Corporation Corporate Bond Ratings:

        AAA - Bonds rated AAA have the highest rating assigned by Standard &
Poor's to a debt obligation and indicate an extremely strong capacity to pay
principal and interest.

                                      A-1
<PAGE>
 
        AA - Bonds rated AA have a very strong capacity to pay interest and
repay principal and differ from the highest rated issues only to a small degree.

        A - Bonds rated A have a strong capacity to pay interest and repay
principal although they are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than bonds in higher rated
categories.

        BBB - Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than for debt in higher rated categories.

        BB, B, CCC, CC - Debt rated BB, B, CCC and CC is regarded, on balance,
as predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and CC the highest degree of speculation. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions.

        C - The rating C is reserved for income bonds on which no interest is
being paid.

        D - Debt rated D is in default, and payment of interest and/or repayment
of principal is in arrears.

II. DESCRIPTION OF U.S. GOVERNMENT SECURITIES

     The term "U.S. Government Securities" refers to a variety of securities
which are issued or guaranteed by the United States Government and by various
instrumentalities which have been established or sponsored by the United States
Government.

     U.S. Treasury securities are backed by the "full faith and credit" of the
United States. Securities issued or guaranteed by Federal agencies and U.S.
Government sponsored instrumentalities may or may not be backed by the full
faith and credit of the United States.

     In the case of securities not backed by the full faith and credit of the
United States, the investor must look principally to the agency or
instrumentality issuing or guaranteeing the obligation for ultimate repayment
and may not be able to assess a claim against the United States itself in the
event the agency or instrumentality does not meet its commitment. Agencies which
are backed by the full faith and credit of the United States include the Export-
Import Bank, Farmers Home Administration, Federal Financing Bank, and others.
Certain agencies and instrumentalities, such as the Government National Mortgage
Association, are, in effect, backed by the full faith and credit of the United
States through provisions in their charters that they may make "indefinite and
unlimited" drawings on the Treasury, if needed, to service its debt. Debt from
certain other agencies and instrumentalities, including the Federal Home Loan
Bank and Federal National Mortgage Association, is not guaranteed by the United
States, but those institutions are protected by the discretionary authority of
the U.S. Treasury to purchase certain amounts of their securities to assist the
institution in meeting its debt obligations. Finally, other agencies and
instrumentalities, such as the Farm Credit System and the Federal Home Loan
Mortgage Corporation, are federally chartered institutions under government
supervision, but their debt securities are backed only by the credit worthiness
of those institutions, not the U.S. Government.

     Some of the U.S. Government agencies that issue or guarantee securities
include the Export-Import Bank of the United States, Farmers Home
Administration, Federal Housing Administration, Maritime Administration, Small
Business Administration, and The Tennessee Valley Authority.

III. DESCRIPTION OF COMMERCIAL PAPER

     The Portfolio may invest in commercial paper (including variable amount
master demand notes) rated A-1 or better by S&P or Prime-1 by Moody's or by S&P.
Commercial paper refers to short-term, unsecured promissory notes issued by
corporations to finance short-term credit needs. Commercial paper is usually
sold on a discount 

                                      A-2
<PAGE>
 
basis and has a maturity at the time of issuance not exceeding nine months.
Variable amount master demand notes are demand obligations that permit the
investment of fluctuating amounts at varying market rates of interest pursuant
to arrangement between the issuer and a commercial bank acting as agent for the
payees of such notes whereby both parties have the right to vary the amount of
the outstanding indebtedness on the notes. As variable amount master demand
notes are direct lending arrangements between a lender and a borrower, it is not
generally contemplated that such instruments will be traded, and there is no
secondary market for these notes, although they are redeemable (and thus
immediately repayable by the borrower) at face value, plus accrued interest, at
any time. In connection with the Portfolio's investment in variable amount
master demand notes, the Adviser's investment management staff will monitor, on
an ongoing basis, the earning power, cash flow and other liquidity ratios of the
issuer and the borrower's ability to pay principal and interest on demand.

     Commercial paper rated A-1 by S&P has the following characteristics: (1)
liquidity ratios are adequate to meet cash requirements; (2) long-term senior
debt is rated "A" or better; (3) the issuer has access to at least two
additional channels of borrowing; (4) basic earnings and cash flow have an
upward trend with allowance made for unusual circumstances; (5) typically, the
issuer's industry is well established, and the issuer has a strong position
within the industry; and (6) the reliability and quality of management are
unquestioned. Relative strength or weakness of the above factors determine
whether the issuer's commercial paper is A-1, A-2 or A-3. The rating Prime-1 is
the highest commercial paper rating assignment by Moody's. Among the factors
considered by Moody's in assigning ratings are the following: (1) evaluation of
the management of the issuer; (2) economic evaluation of the issuer's industry
or industries and the appraisal of speculative-type risks which may be inherent
in certain areas; (3) evaluation of the issuer's products in relation to
completion and customer acceptance; (4) liquidity; (5) amount and quality of
long term debt; (6) trend of earnings over a period of ten years; (7) financial
strength of a parent company and the relationships which exist with the issuer;
and (8) recognition by the management of issuer of obligations which may be
present or may arise as a result of public interest questions and preparations
to meet such obligations.

IV. DESCRIPTION OF BANK OBLIGATIONS

     Time deposits are non-negotiable deposits maintained in a banking
institution for a specified period of time at a stated interest rate.
Certificates of deposit are negotiable short-term obligations of commercial
banks. Variable rate certificates of deposit are certificates of deposit on
which the interest rate is periodically adjusted prior to their stated maturity
based upon a specified market rate. As a result of these adjustments, the
interest rate on these obligations may increase or decrease periodically.
Frequently, dealers selling variable rate certificates of deposit to the
Portfolio will agree to repurchase such instruments, at the Portfolio's option,
at par on or near the coupon dates. The dealers' obligations to repurchase these
instruments are subject to conditions imposed by various dealers. Such
conditions typically are the continued credit standing of the issuer and the
existence of reasonably orderly market conditions. The Portfolio is also able to
sell variable rate certificates of deposit in the secondary market. Variable
rate certificates of deposit normally carry a higher interest rate than
comparable fixed rate certificates of deposit. A bankers' acceptance is a time
draft drawn on a commercial bank by a borrower usually in connection with an
international commercial transaction to finance the import, export, transfer or
storage of goods. The borrower is liable for payment as well as the bank which
unconditionally guarantees to pay the draft at its face amount on the maturity
date. Most acceptances have maturities of six months or less and are traded in
the secondary markets prior to maturity.
