Dear Arrow Fund Shareholder:

     The Board of Trustees of Arrow Funds has called a special meeting to
consider a proposal that could improve the level of services available to
shareholders. At this meeting, shareholders of the Arrow Equity, Arrow Fixed
Income and Arrow Municipal Income Portfolios (the "Arrow Portfolios") will be
asked to approve a proposal to combine the Arrow Portfolios with The ARCH Fund,
Inc. -- a $3 billion mutual fund complex managed by Mississippi Valley Advisors
Inc.

   
     After carefully studying the merits of the proposal, the Board of Trustees
has determined that a consolidation between the two fund families will provide
substantial value for Arrow Portfolio shareholders. To move forward, however, a
majority of the shareholders of the Arrow Portfolios must first vote in favor of
the transaction. Accordingly, enclosed you'll find a proxy card for the upcoming
shareholder meeting scheduled to be held on November 11, 1997. IT IS IMPORTANT
THAT YOU COMPLETE, SIGN AND RETURN YOUR CARD AS SOON AS POSSIBLE TO ENSURE YOUR
VOTE IS COUNTED AT THE MEETING.     

     The Arrow Fund Board of Trustees unanimously endorses the proposed
reorganization that is discussed in detail in the combined proxy statement and
fund prospectus we've sent to you. The consolidation of the Arrow Portfolios
with The ARCH Fund, Inc. will benefit shareholders in two key ways:

          1. Shareholders will now be able to choose from 18 investment
     portfolios versus the 4 investment portfolios that are now available
     through Arrow Funds. The wide array of additional investment options will
     include international, asset allocation and market index funds.
     Shareholders will also be able to exchange from one portfolio to another
     without incurring any transaction charges.

          2. By combining the assets of the Arrow Portfolios and the ARCH Funds,
     fund expense ratios may decline, which would ultimately translate into
     better returns for fund shareholders.

     The reorganization of the Arrow Portfolios into The ARCH Fund, Inc.,
pending shareholder approval, is slated for late November 1997. In connection
with the reorganization, you should note the following:

     - Trust shareholders will be able to continue to invest on a no load basis.

     - The reorganization will be a tax free event.

   
     - Two Arrow portfolios -- the Arrow Fixed Income Portfolio and the Arrow
       Municipal Income Portfolio -- will be combined into comparable ARCH
       portfolios with similar investment objectives and policies and that are
       managed by the same investment professionals at Mississippi Valley
       Advisors Inc. One Arrow portfolio -- the Arrow Equity Portfolio -- will
       be reorganized into a newly created portfolio within The ARCH Fund, Inc.
       and that will continue to be managed by Carl Enloe, who has managed the
       Arrow Equity Portfolio since its inception. The remaining Arrow portfolio
       -- the Arrow Government Money Market Portfolio -- will be liquidated
       prior to the reorganization.
    

     - The value of your investment will not change as a result of the
       reorganization.

     The enclosed materials should provide you with the necessary details to
make an informed decision about the proposal.

     We are truly excited about the reorganization and the potential benefits it
provides to current shareholders who invest in the Arrow Portfolios. Hopefully,
you will agree by voting "yes" and returning your proxy card as soon as
possible.

                                       Sincerely,

   
                                       John F. Donahue

     This Combined Proxy Statement/Prospectus is furnished in connection with
the solicitation of proxies by the Board of Trustees of Arrow Funds ("Arrow") in
connection with a Special Meeting (the "Meeting") of Shareholders
("Shareholders") of Arrow's Fixed Income, Municipal Income and Equity Portfolios
to be held on November 11, 1997 at 2:00 p.m. Eastern Time at Federated Investors
Tower, 1001 Liberty Avenue, 19th Floor, Pittsburgh, Pennsylvania 15222-3779, at
which Shareholders will be asked to consider and approve a proposed Agreement
and Plan of Reorganization dated September 12, 1997 (the "Reorganization
Agreement"), by and between Arrow and The Arch Fund, Inc. ("Arch") and the
matters contemplated therein. A copy of the Reorganization Agreement is attached
as Appendix I.     

     Arrow and Arch are open-end, series, management investment companies. As a
result of the recent merger of Mark Twain Bancshares, Inc., the parent of
Arrow's former investment adviser, Mark Twain Bank, and Mercantile
Bancorporation Inc. (the "Holding Company Merger"), Mississippi Valley Advisors
Inc. ("MVA") and its affiliates are now providing investment advisory and other
services to both Arch and Arrow. MVA and its affiliates are subsidiaries of
Mercantile Bancorporation Inc. In reviewing the proposed reorganization (the
"Reorganization"), the Arrow Board considered the consummation of the Holding
Company Merger; the recommendation of MVA that Arrow and Arch be consolidated in
an effort to promote more efficient operations, eliminate duplicative costs and
enhance the distribution of shares by eliminating market overlap; the fact that
the Reorganization would constitute a tax-free reorganization; and the fact that
the interests of Shareholders would not be diluted as a result of the
Reorganization.

     The Reorganization Agreement provides that initially each of the following
two investment portfolios of Arrow (collectively, the "Reorganizing Portfolios")
will transfer substantially all its assets and known liabilities to the existing
Arch investment portfolio (collectively, the "Existing Arch Portfolios")
identified below opposite its name:

<TABLE>

             REORGANIZING PORTFOLIOS                   EXISTING ARCH PORTFOLIOS

            Municipal Income Portfolio            National Municipal Bond Portfolio
</TABLE>

<PAGE>

     The Reorganization Agreement also provides that the following investment
portfolio of Arrow (the "Continuing Portfolio") will subsequently transfer all
its assets and known liabilities to the newly-organized Arch investment
portfolio (the "New Arch Portfolio") identified below opposite its name:

<TABLE>
<CAPTION>
               CONTINUING PORTFOLIO                       NEW ARCH PORTFOLIO
    ------------------------------------------------------------------------------------

                 Equity Portfolio                      Growth Equity Portfolio
</TABLE>

     In exchange for the transfers of these assets and liabilities, Arch will
issue shares in the three Arch investment portfolios listed above (collectively,
the "Arch Portfolios") to the corresponding Arrow investment portfolios listed
above (collectively, the "Arrow Portfolios"). The initial transaction between
the Reorganizing Portfolios and the Existing Arch Portfolios is referred to
herein as the "Reorganizing Portfolios Transaction" and the subsequent
transaction between the Continuing Portfolio and the New Arch Portfolio is
referred to herein as the "Continuing Portfolio Transaction." The transactions
are expected to occur on or after November 14, 1997 and November 21, 1997,
respectively.

     Prior to the Reorganizing Portfolios Transaction, it is expected that all
of the shareholders in the Arrow Government Money Market Portfolio will redeem
their shares in that portfolio.

   
     The Arrow Portfolios have one class of shares outstanding. The Arch
Government & Corporate Bond and Arch Growth Equity Portfolios have four classes
of shares outstanding (Trust Shares, Institutional Shares, Investor A Shares and
Investor B Shares) and the Arch National Municipal Bond Portfolio has three
classes of shares outstanding (Trust Shares, Investor A Shares and Investor B
Shares). Holders of shares of an Arrow Portfolio will receive Investor A Shares
(which are similar to shares of the Arrow Portfolios) of the corresponding Arch
Portfolio as set forth in the table on page 15 under "Information Relating to
the Proposed Reorganization -- Description of the Reorganization Agreement."
    

     The Arrow Portfolios will make liquidating distributions of the Arch
Portfolios' shares to the Shareholders of the Arrow Portfolios, so that a holder
of shares in an Arrow Portfolio will receive Investor A Shares of the
corresponding Arch Portfolio with the same aggregate net asset value as the
Shareholder had in the Arrow Portfolio immediately before the transaction.
Following the Reorganization, Shareholders of the Arrow Portfolios will be
shareholders of the corresponding Arch Portfolios, and Arrow will be
deregistered as an investment company under the Investment Company Act of 1940,
as amended (the "1940 Act") and its existence will be terminated under state
law.

   
     At September 12, 1997, Mercantile Bank National Association ("Mercantile
Bank"), an affiliate of MVA, owned of record with the power to vote
approximately 96.42% of the outstanding shares of the Arrow Portfolios on behalf
of customers maintaining fiduciary, employee benefit, retirement plan or other
qualified accounts at Mercantile Bank. Arch and Arrow have been advised by
Mercantile Bank that it intends to exchange the Investor A Shares of the Arch
Portfolios that it receives in these capacities for Trust Shares of the same
Arch Portfolios. Mercantile Bank intends to effect this exchange, which it has
been advised by Drinker Biddle & Reath LLP will not cause shareholders to
recognize taxable gains or losses, promptly after the Reorganization because it
believes that Trust Shares are more appropriate than Investor A Shares for these
customers.     

                                       ii

<PAGE>

     The Existing Arch Portfolios currently are conducting investment operations
as described in this Combined Proxy Statement/Prospectus. The New Arch Portfolio
has recently been organized for the purpose of continuing the investment
operations of the Arrow Equity Portfolio.

   
     This Combined Proxy Statement/Prospectus sets forth the information that a
Shareholder of an Arrow Portfolio should know before voting on the
Reorganization Agreement (and related transactions), and should be retained for
future reference. The Prospectus relating to Investor A Shares of the Existing
Arch Portfolios dated March 31, 1997 (as supplemented August 29, 1997), which
describes the operations of those Portfolios, accompanies this Combined Proxy
Statement/Prospectus. Additional information is set forth in the Statements of
Additional Information relating to those Portfolios and this Combined Proxy
Statement/Prospectus, which are dated March 31, 1997 (as revised August 29,
1997) and September 15, 1997, respectively, and in the Prospectus dated November
30, 1996 (as supplemented April 25, 1997) and Combined Statement of Additional
Information dated November 30, 1996, relating to the Arrow Portfolios. Each of
these documents is on file with the Securities and Exchange Commission (the
"SEC"), and is available without charge upon oral or written request by writing
or calling either Arrow or Arch at the respective addresses or telephone numbers
indicated above. The information contained in the Prospectus dated November 30,
1996 (as supplemented April 25, 1997) and Combined Statement of Additional
Information dated November 30, 1996, relating to the Arrow Portfolios is
incorporated herein by reference.     

     This Combined Proxy Statement/Prospectus constitutes the Proxy Statement of
Arrow for the Meeting of its Shareholders, and Arch's Prospectus for the
Investor A Shares of the Existing Arch Portfolios that have been registered with
the SEC and are to be issued in connection with the Reorganization. Because the
operations of the Arrow Equity Portfolio will be carried on by the New Arch
Portfolio, this Combined Proxy Statement/Prospectus does not constitute a
prospectus for the Investor A Shares of the New Arch Portfolio that will be
issued in the Continuing Portfolio Transaction.

   
     This Combined Proxy Statement/Prospectus is expected to first be sent to
Shareholders on or about September 24, 1997.
    

     THE SECURITIES OF THE ARCH PORTFOLIOS HAVE NOT BEEN APPROVED OR DISAPPROVED
BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR
HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
PASSED UPON THE ACCURACY OR ADEQUACY OF THIS COMBINED PROXY

     PROPOSED REORGANIZATION. Based upon their evaluation of the relevant
information presented to them, and in light of their fiduciary duties under
federal and state law, Arrow's and Arch's Boards of Trustees and Directors,
respectively, including their members who are not "interested persons" within
the meaning of the 1940 Act, have determined that the proposed Reorganization is
in the best interests of Arrow's and Arch's Shareholders, respectively, and that
the interests of existing Shareholders of Arrow and Arch, respectively, will not
be diluted as a result of such Reorganization.     

   
     The Cover Page and pages 15-19 hereof summarize the proposed
Reorganization.
    

   
     REASONS FOR THE REORGANIZATION. The primary reason for the Reorganization
is the Holding Company Merger of Mark Twain Bancshares, Inc. and Mercantile
Bancorporation Inc. Consummation of the Holding Company Merger on April 25, 1997
resulted in the automatic termination of the existing investment advisory
agreement between the Arrow Portfolios and Mark Twain Bank, a wholly-owned
subsidiary of Mark Twain Bancshares, Inc. In anticipation of the Holding Company
Merger and to provide continuity in investment advisory services to the Arrow
Portfolios, shareholders of the Arrow Portfolios approved a new investment
advisory agreement with MVA, a wholly-owned subsidiary of Mercantile Bank and an
indirect wholly-owned subsidiary of Mercantile Bancorporation Inc., effective
April 25, 1997.     

     MVA has recommended that each of the Arrow Portfolios be reorganized as
described in this Combined Proxy Statement/Prospectus in an effort to promote
more efficient operations, eliminate duplicative costs and enhance the
distribution of shares by eliminating market overlap. In light of this
recommendation, after consideration of the reasons therefor and the proposed
operations of the combined portfolios after the Reorganization, and in
consideration of the fact that the Reorganization will be tax-free and will not
dilute the interests of Arrow Shareholders, the Board of Trustees of Arrow has
authorized the Agreement and Plan of Reorganization and recommended approval of
the Reorganization by Shareholders.

   
     FEDERAL INCOME TAX CONSEQUENCES. Shareholders of the Arrow Portfolios will
recognize no gain or loss for federal income tax purposes on their receipt of
Investor A Shares of the Arch Portfolios. Shareholders of the Arch Portfolios
will have no federal tax consequences from the Reorganization. The Arch
Portfolios will incur no federal tax consequences from their issuance of
Investor A Shares in the Reorganization. See "Information Relating to the
Proposed Reorganization -- Federal Income Tax Consequences."     

   
     OVERVIEW OF THE ARROW PORTFOLIOS AND ARCH PORTFOLIOS.  There are no
material differences between the investment objectives and policies of the
Continuing Portfolio and the New Arch Portfolio. The investment
    

                                        1

<PAGE>

objectives and policies of the Reorganizing Portfolios are similar to those of
the corresponding Existing Arch Portfolios.

ARROW FIXED INCOME PORTFOLIO AND ARCH GOVERNMENT & CORPORATE BOND PORTFOLIO

     The Arrow Fixed Income Portfolio's investment objective is current income.
The Arch Government & Corporate Bond Portfolio's investment objective is to seek
the highest level of current income consistent with conservation of capital.
Each Portfolio pursues its objective by investing in a diversified portfolio of
U.S. Government and investment grade corporate debt securities.

ARROW MUNICIPAL INCOME PORTFOLIO AND ARCH NATIONAL MUNICIPAL BOND PORTFOLIO

     The Arrow Municipal Income Portfolio's investment objective is current
income which is exempt from federal regular income tax. The Arch National
Municipal Bond Portfolio's investment objective is to seek as high a level of
current income exempt from regular federal income tax as is consistent with
conservation of capital. Each Portfolio pursues its objective by investing at
least 80% of its total assets in a diversified portfolio of municipal
securities.

     See "Comparison of Investment Policies and Risk Factors" below and the
Arrow Prospectus for the Arrow Portfolios and the Arch Prospectus for Investor A
Shares of the Existing Arch Portfolios, which are incorporated herein by
reference, for a description of the similarities and differences between the
investment objectives and policies of the Reorganizing Portfolios and the
Existing Arch Portfolios.

* Paid to Mark Twain Bank pursuant to the investment advisory agreement then in
  effect.

     Pursuant to the Arrow investment advisory agreement, MVA provides
investment research and supervision to the Arrow Portfolios and conducts a
continuous program of investment evaluation and of appropriate sale or other
disposition of each Arrow Portfolio's assets. MVA also directs the investments
of the Arrow Portfolios in accordance with the Portfolios' investment
objectives, policies and limitations, and creates and maintains all necessary
books and records.

     Administrative services are provided to the Arrow Portfolios by Federated
Administrative Services ("Federated"), a subsidiary of Federated Investors. For
its services, Federated receives a fee, calculated and paid daily, at the annual
rate of .15% of the average aggregate daily net assets of all investment
portfolios of Arrow up to $250 million of such aggregate assets, .125% of the
next $250 million of such aggregate assets, .10% of the next $250 million of
such aggregate assets, and .075% of such aggregate assets in excess of $750
million. The minimum annual administration fee for each investment portfolio of
Arrow is $50,000. For the

                                        2

<PAGE>

fiscal year ended September 30, 1996, Federated received administration fees at
the effective annual rates of .17%, .29% and .15% of the average daily net
assets of the Fixed Income, Municipal Income and Equity Portfolios,
respectively.

     Federated Services Company, a subsidiary of Federated Investors, serves as
Arrow's transfer agent, dividend disbursing agent and portfolio recordkeeper.

     Mercantile Bank provides custodial services to each Arrow Portfolio.

     Federated Securities Corp. ("FSC"), a subsidiary of Federated Investors, is
the principal distributor for Arrow. Under the distribution agreement, FSC acts
as the agent of Arrow in connection with the offering of shares of each Arrow
Portfolio.

     Arrow has adopted a Distribution Plan pursuant to Rule 12b-1 under the 1940
Act (the "Arrow 12b-1 Plan"). Under the Arrow 12b-1 Plan, the shares of each
Arrow Portfolio bear the expense of distribution fees payable to FSC at an
annual rate of up to .25% of the average daily net asset value of such
Portfolio's outstanding shares to finance activities which are principally
intended to result in the sale of shares subject to the Arrow 12b-1 Plan. FSC
may enter into agreements with financial institutions which provide distribution
and/or administrative services as agents for their customers who beneficially
own shares. Administrative services provided by such financial institutions may
include, without limitation: providing office space, equipment, telephone
facilities, and various clerical, supervisory, computer, and other personnel as
necessary or beneficial to establish and maintain shareholder accounts and
records; processing purchase and redemption transactions and automatic
investments of client account cash balances; answering routine client inquiries;
assisting clients in changing dividend options, account designations, and
addresses; and providing such other services as may reasonably be requested.

   
     The Arrow 12b-1 Plan is a "compensation" type plan as opposed to a
"reimbursement" type plan. Accordingly, payments by the Arrow Portfolios under
the Arrow 12b-1 Plan are based on the expressed fee rather than on specific
amounts expended by FSC for distribution purposes. FSC may earn a profit from
payments made by the Arrow Portfolios under the Arrow 12b-1 Plan.
    

     For the fiscal year ended September 30, 1996, FSC was entitled to receive
fees from the Arrow Portfolios pursuant to the Arrow 12b-1 Plan in the aggregate
amount of $238,312, all of which was voluntarily waived. Such fees represent
 .25% of the average daily net assets of the Arrow Portfolios during such period.

     BISYS Fund Services ("BISYS"), an affiliate of BISYS Ohio, serves as
distributor of the shares of Arch's investment portfolios.

     Arch has adopted a Distribution and Services Plan pursuant to Rule 12b-1
under the 1940 Act (the "Arch 12b-1 Plan") with respect to Investor A Shares of
its investment portfolios. Under the Arch 12b-1 Plan, Investor A Shares of each
of the Arch Portfolios bear the expense of (i) distribution fees paid to BISYS
at an annual rate of up to .10% of the average daily net assets of such
Portfolio's outstanding Investor A Shares in consideration for distribution
services and the assumption of related expenses primarily intended to result in
the sale of Investor A Shares, and (ii) shareholder servicing fees paid to
securities brokers, dealers and other such organizations ("Service
Organizations") for administrative support services provided to their customers
who are the beneficial owners of Investor A Shares at the annual rate of up to
 .20% of the average daily net asset value of such Portfolio's Investor A Shares
beneficially owned by such customers. The Arch 12b-1 Plan authorizes Arch to
enter into servicing agreements with Service Organizations that require the
Service Organizations receiving such compensation to perform certain services
with respect to the beneficial owners of Investor A Shares of an Arch Portfolio,
such as establishing and maintaining accounts and records for their customers
who invest in such Shares, assisting customers in processing purchase, exchange
and redemption requests, and responding to customer inquiries regarding their
investments.

     The Arch 12b-1 Plan is a "compensation" type plan as opposed to a
"reimbursement" type plan. Accordingly, payments by the Arch Portfolios under
the Arch 12b-1 Plan are based on the expressed fee rather than on specific
amounts expended by BISYS for distribution purposes. BISYS may earn a profit
from payments made by the Arch Portfolios under the Arch 12b-1 Plan.

   
     For the fiscal year ended November 30, 1996, the Existing Arch Portfolios
paid fees to BISYS and other broker-dealers pursuant to the Arch 12b-1 Plan in
the aggregate amount of $15,982, which represents .30% of the average daily net
assets of the Existing Arch Portfolios' Investor A Shares during that period
subject to the Arch 12b-1 Plan.     

     Arch has adopted an Administrative Services Plan (the "Arch Services Plan")
with respect to Trust Shares of its investment portfolios. Under the Arch
Services Plan, Trust Shares of each of the Arch Portfolios bear the expense of
shareholder servicing fees paid to Service Organizations for administrative
services provided to their customers who are the beneficial owners of Trust
Shares at the annual rate of up to .30% of the average daily net asset value of
such Portfolio's Trust Shares beneficially owned by such customers. Like the
Arch 12b-1 Plan, the Arch Services Plan authorizes Arch to enter into servicing
agreements with Service Organizations that require the Service Organizations
receiving such compensation to perform certain services with respect to the
beneficial owners of Trust Shares of an Arch Portfolio. These services are the
same services which Service Organizations are required to provide under the Arch
12b-1 Plan described above.

     For the fiscal year ended November 30, 1996, the Existing Arch Portfolios
paid fees to Service Organizations pursuant to the Arch Services Plan in the
aggregate amount of $157 which represents .30% of the average daily net assets
of the Existing Arch Portfolios' Trust Shares during that period subject to the
Plan.

     VOTING INFORMATION. This Combined Proxy Statement/Prospectus is being
furnished in connection with the solicitation of proxies by Arrow's Board of
Trustees in connection with a Special Meeting of Shareholders to be held at
Federated Investors Tower, 1001 Liberty Avenue, 19th Floor, Pittsburgh,
Pennsylvania, on Tuesday, November 11, 1997 at 2:00 p.m. Eastern Time (such
meeting and any adjournments thereof hereinafter referred to as the "Meeting").
Only Shareholders of record at the close of business on September 12, 1997 will
be entitled to notice of and to vote at the Meeting. Each share or fraction
thereof is entitled to one vote or fraction thereof and all shares will vote
separately by Portfolio. Shares represented by a properly executed proxy will be
voted in accordance with the instructions thereon, or if no specification is
made, the persons named as proxies will vote in favor of each proposal set forth
in the Notice of Meeting. Proxies may be revoked at any time before they are
exercised by submitting to Arrow a written notice of revocation or a
subsequently executed proxy or by attending the Meeting and voting in person.
For additional information, including a description of the Shareholder vote
required for approval of the Reorganization Agreement and related transactions
contemplated thereby, see "Information Relating to Voting Matters."     

   
     RISK FACTORS. The following discussion highlights the principal risk
factors associated with an investment in the Reorganizing Portfolios and the
Existing Arch Portfolios and is qualified in its entirety by the more extensive
discussion of risk factors in "Comparison of Investment Policies and Risk
Factors."     

     Because of the similarities of the investment objectives and policies of
the Reorganizing Portfolios and the corresponding Existing Arch Portfolios,
management believes that an investment in an Existing Arch Portfolio involves
risks that are similar to those of the corresponding Reorganizing Portfolio.
These investment risks include those typically associated with investing in a
diversified portfolio of government or investment grade corporate bonds in the
case of the Arrow Fixed Income Portfolio and in a diversified portfolio of
municipal securities in the case of the Arrow Municipal Income Portfolio.

     There are differences, however, between the Reorganizing Portfolios and the
Existing Arch Portfolios, as described below under "Comparison of Investment
Policies and Risk Factors." These differences can result in

                                       13

<PAGE>

different risks. For example, the Arrow Fixed Income Portfolio will only invest
in investment grade debt securities, i.e. securities rated in one of the four
highest rating categories assigned by one or more rating agencies or, if
unrated, determined by MVA to be of comparable quality. The Arch Government &
Corporate Bond Portfolio also will only invest in investment grade debt
securities, provided, however, that at least 65% of its assets will be invested
in debt securities rated within the three highest rating categories assigned by
one or more rating agencies or, if unrated, determined by MVA to be of
comparable quality. Similarly, the Arrow Municipal Income Portfolio will only
invest in investment grade municipal securities. The Arch National Municipal
Bond Portfolio also will only invest in investment grade municipal securities,
provided, however, that at least 65% of its assets will be invested in municipal
securities rated in one of the three highest rating categories assigned by one
or more rating agencies or, if unrated, determined by MVA to be of comparable
quality. Debt securities, including municipal securities, rated in the lowest
investment grade rating category do not have outstanding investment
characteristics and may have speculative characteristics as well.

     The Arrow Fixed Income Portfolio may invest up to 10% of its assets in
investment grade debt securities of foreign issuers. The Arch Government &
Corporate Bond Portfolio may invest up to 10% of its total assets in
dollar-denominated debt obligations of foreign issuers, either directly or
indirectly through American Depository Receipts ("ADRs") and European Depository
Receipts ("EDRs"). Investments in the securities of foreign issuers, whether
made directly or indirectly, carry certain risks not ordinarily associated with
investments in the securities of domestic issuers.

   
     The Arch Government & Corporate Bond Portfolio and the Arrow Fixed Income
Portfolio may each purchase put and call options listed on a national securities
exchange and issued by the Options Clearing Corporation and write covered call
options (and covered put options in the case of the Arrow Fixed Income
Portfolio) listed on a national securities exchange and issued by the Options
Clearing Corporation. Unlike the Arch Government & Corporate Bond Portfolio, the
Arrow Fixed Income Portfolio may also purchase and write unlisted
over-the-counter options which are not subject to the protections afforded by
the Options Clearing Corporation. The Arrow Municipal Income Portfolio may
purchase and write listed and unlisted options as described above, whereas the
Arch National Municipal Bond Portfolio may not enter into options transactions.
    

     The Arch Government & Corporate Bond Portfolio and the Arrow Fixed Income
Portfolio may each purchase mortgage-related asset-backed securities. Unlike the
Arrow Fixed Income Portfolio, the Arch Government & Corporate Bond Portfolio may
purchase non-mortgage-related asset-backed securities, which involve certain
risks that are not presented by mortgage-related asset-backed securities arising
primarily from the nature of the underlying collateral (i.e. credit card
receivables and automobile loan receivables as opposed to real estate
mortgages).

     Unlike the Arch National Municipal Bond Portfolio, the Arrow Municipal
Income Portfolio may enter into repurchase agreements and reverse repurchase
agreements. Default by a counterparty to a repurchase agreement could expose a
Portfolio to loss because of adverse market action or possible delay in
disposing of the underlying collateral. Reverse repurchase agreements are
subject to the risk that the market value of the securities sold by a Portfolio
will decline below the repurchase price which the Portfolio is obligated to pay.

     The per share price of the Reorganizing Portfolios and the Existing
Portfolios will fluctuate with changes in the value of the investments held by
each Portfolio. Generally, the market value of debt securities will vary

                                       14

<PAGE>

inversely to changes in prevailing interest rates. There is no assurance that
any Portfolio will achieve its investment objective.

              INFORMATION RELATING TO THE PROPOSED REORGANIZATION

     Arrow has entered into an agreement whereby its investment portfolios
(other than the Arrow Government Money Market Portfolio) are to be acquired by
investment portfolios of Arch. Significant provisions of the Reorganization
Agreement are summarized below; however, this summary is qualified in its
entirety by reference to the Reorganization Agreement, a copy of which is
attached as Appendix I to this Combined Proxy Statement/Prospectus.

   
     DESCRIPTION OF THE REORGANIZATION AGREEMENT. There are four separate Arrow
investment portfolios. Prior to the consummation of the transactions
contemplated by the Reorganization Agreement, it is anticipated that
shareholders of the Arrow Government Money Market Portfolio will redeem their
shares in that portfolio. The initial transaction in the Reorganization is that
the assets of the two Arrow Reorganizing Portfolios will be acquired by two
similar investment portfolios currently offered by Arch. Afterwards, the Arrow
Continuing Portfolio will be acquired by the New Arch Portfolio which has been
organized to continue its operations.     

     The Reorganization Agreement provides, first, that substantially all of the
assets and liabilities of the Reorganizing Portfolios will be transferred to the
Existing Arch Portfolios identified in the table below. Not less than seven
calendar days thereafter, substantially all of the assets and liabilities of the
Continuing Portfolio will be transferred to the New Arch Portfolio identified in
the table below. The holders of shares of an Arrow Portfolio will receive
Investor A Shares of the corresponding Arch Portfolio identified in the table.
The number of Investor A Shares to be issued by each Arch Portfolio will have an
aggregate net asset value equal to the aggregate net asset value of the shares
of the corresponding Arrow Portfolio as of the regular close of the New York
Stock Exchange, currently 4:00 p.m. Eastern Time, on the same business day on
which each transaction will be consummated. The number of Investor A Shares
received by an Arrow shareholder may be different from the number of Arrow
shares previously held, but the value of such shares in the aggregate will equal
the aggregate value held previously by such shareholders. Arrow shareholders
will not pay a sales charge in connection with their receipt of Investor A
Shares of the Arch Portfolios.

     The Reorganization Agreement provides that Arrow will declare a dividend or
dividends prior to the Reorganizing Portfolios Transaction which, together with
all previous dividends, will have the effect of distributing to the Shareholders
of each of the Reorganizing Portfolios all undistributed ordinary income earned
and net capital gains realized up to and including the effective time of the
Reorganizing Portfolios Transaction.

                                       15

<PAGE>

     Following the transfers of assets and liabilities from the Arrow Portfolios
to the Arch Portfolios, and the issuances of Investor A Shares by the Arch
Portfolios to the Arrow Portfolios, each of the Arrow Portfolios will distribute
the Investor A Shares of the Arch Portfolios pro rata to the holders of shares
of the Arrow Portfolios as described above in liquidation of the Arrow
Portfolios. Each holder of shares of an Arrow Portfolio will receive an amount
of Investor A Shares of the corresponding Arch Portfolio of equal value, plus
the right to receive any declared and unpaid dividends or distributions.
Following the Reorganization, Shareholders of the Arrow Portfolios will be
shareholders of the corresponding Arch Portfolios, and Arrow will be
deregistered as an investment company under the 1940 Act and its existence
terminated under state law.

   
     At September 12, 1997, Mercantile Bank owned of record with the power to
vote approximately 96.42% of the outstanding shares of the Arrow Portfolios on
behalf of customers maintaining fiduciary, employee benefit, retirement plan or
other qualified accounts at Mercantile Bank. Arch and Arrow have been advised by
Mercantile Bank that it intends to exchange the Investor A Shares of the Arch
Portfolios that it receives in these capacities for Trust Shares of the same
Arch Portfolios. Mercantile Bank intends to effect this exchange, which it has
been advised by Drinker Biddle & Reath LLP will not cause shareholders to
recognize taxable gains or losses, promptly after the Reorganization because it
believes that Trust Shares are more appropriate than Investor A Shares for these
customers.     

     The stock transfer books of Arrow will be permanently closed after the
Reorganization. If any Arrow Portfolio shares held by a former Arrow Portfolio
shareholder are represented by share certificates, the certificate must be
surrendered to Arch's transfer agent for cancellation before the Arch Portfolio
shares issued to the shareholder in the Reorganization may be redeemed. Arch
will not issue share certificates with respect to the Arch Portfolio shares
issued in connection with the Reorganization.

     The Reorganization is subject to a number of conditions, including approval
of the Reorganization Agreement and the transactions contemplated thereby as
described in this Combined Proxy Statement/Prospectus by the Shareholders of the
Arrow Portfolios; the receipt of certain legal opinions described in the
Reorganization Agreement; the receipt of certain certificates from the parties
concerning the continuing accuracy of the representations and warranties in the
Reorganization Agreement and other matters; and the parties' performance in all
material respects of their agreements and undertakings in the Reorganization
Agreement. Assuming satisfaction of the conditions in the Reorganization
Agreement, the Reorganizing Portfolios Transaction is expected to occur on or
after November 14, 1997 and the Continuing Portfolio Transaction is expected to
occur on or after November 21, 1997.

   
     Arch and Arrow will each be responsible for the payment of its own expenses
incurred in connection with the Reorganization. Arch estimates that it will bear
approximately $75,000 of the total cost of the Reorganization and Arrow
estimates that it will bear approximately $20,000 of the total cost of the
Reorganization. If the Reorganization is consummated, the expenses of the Arrow
Portfolios will be assumed by the corresponding Arch Portfolios.
    

     The Reorganization may be terminated at any time prior to its consummation
by Arch or Arrow if the conditions specified in the Reorganization Agreement are
not satisfied or by the mutual consent of Arch and Arrow. The Reorganization
Agreement provides further that at any time prior to or (to the fullest extent
permitted by law) after approval of the Reorganization Agreement by the
Shareholders of Arrow (a) the parties thereto may, by written agreement approved
by their respective Boards of Trustees or Directors or authorized officers and
with or without the approval of their shareholders, amend any of the provisions
of the

                                       16

<PAGE>

Reorganization Agreement; and (b) either party may waive any breach by the other
party or the failure to satisfy any of the conditions to its obligations with or
without the approval of such party's shareholders.

     Section 15(f) of the 1940 Act provides that when a change in the control of
an investment adviser occurs, the investment adviser or any of its affiliated
persons may receive any amount or benefit in connection therewith under certain
conditions. One condition is that for three years thereafter, at least 75% of
the board of directors of the surviving investment company are not "interested
persons" of the company's investment adviser or of the investment adviser of the
terminating investment company. Another condition is that no "unfair burden" is
imposed on the investment company as a result of the transaction relating to the
change of control, or any express or implied terms, conditions or understandings
applicable thereto. The term "unfair burden" as defined in the 1940 Act includes
any arrangement during the two-year period after the transaction whereby the
investment adviser (or predecessor or successor adviser), or any "interested
person" of any such adviser, receives or is entitled to receive any
compensation, directly or indirectly, from the investment company or its
security holders (other than fees for bona fide investment advisory or other
services) or from any person in connection with the purchase or sale of
securities or other property to, from or on behalf of the investment company
(other than fees for bona fide principal underwriting services). Arch intends to
comply with the conditions set forth in Section 15(f).

     In its consideration and approval of the Reorganization at a meeting on
August 18, 1997, the Board of Trustees of Arrow considered the effect of the
Holding Company Merger of Mark Twain Bancshares, Inc. and Mercantile
Bancorporation Inc. on Arrow; the recommendation of MVA with respect to the
proposed consolidation of Arrow and Arch; the tax-free nature of the
Reorganization; and the fact that the interests of Shareholders would not be
diluted as a result of the Reorganization.

     After consideration of all of the foregoing factors, together with certain
other factors and information considered to be relevant, Arrow's Board of
Trustees unanimously approved the Reorganization Agreement and directed that it
be submitted to Shareholders for approval. ARROW'S BOARD OF TRUSTEES RECOMMENDS
THAT SHAREHOLDERS VOTE "FOR" APPROVAL OF THE REORGANIZATION AGREEMENT.

     The Board of Trustees of Arrow has not determined what action it will take
in the event the Shareholders of any Arrow Portfolio fail to approve the
Reorganization Agreement or for any reason the Reorganization is not
consummated. In either such event, the Trustees may choose to consider
alternative dispositions of the Arrow Portfolios' assets, including the sale of
assets to, or merger with, another investment company, or the possible
liquidation of any of the Arrow Portfolios.

     At a meeting held on June 17, 1997, the Arch Board of Directors considered
the proposed Reorganization. Based upon their evaluation of the relevant
information provided to them, and in light of their fiduciary duties under
federal and state law, the Board of Directors unanimously determined that the
proposed Reorganization was in the best interests of the Arch Portfolios and
their respective shareholders and that the interests of existing shareholders of
the Arch Portfolios would not be diluted as a result of effecting the
transaction.

   
     CAPITALIZATION. Because the Reorganizing Portfolios will be combined in the
Reorganization with the Existing Arch Portfolios, the total capitalization of
each of the Existing Arch Portfolios after the Reorganization is expected to be
greater than the current capitalization of the corresponding Reorganizing
Portfolios. The following table sets forth (i) the capitalization of each of the
Reorganizing Portfolios as of May 31, 1997;     

                                       17

<PAGE>

(ii) the capitalization of each of the Existing Arch Portfolios as of May 31,
1997; and (iii) the pro forma capitalization of each of the Existing Arch
Portfolios as adjusted to give effect to the Reorganization. If consummated, the
capitalization of each Portfolio is likely to be different at the time of the
Reorganizing Portfolios Transaction as a result of daily share purchase and
redemption activity in the Portfolios.

     FEDERAL INCOME TAX CONSEQUENCES. Consummation of the Reorganization is
subject to the condition that Arrow and Arch receive an opinion from Drinker
Biddle & Reath LLP, based on certain factual assumptions and in reliance on
certain factual representations by the management of Arrow and Arch, to the
effect that for federal income tax purposes: (i) the transfer of all of the
assets and liabilities of each of the Arrow Portfolios to the corresponding Arch
Portfolio in exchange for Investor A Shares of the corresponding Arch Portfolio
and the liquidating distribution to Shareholders of the Arrow Portfolio of the
Investor A Shares of the Arch Portfolio so received, as described in the
Reorganization Agreement, will constitute a reorganization within the meaning of
Section 368(a)(1)(C), Section 368(a)(1)(D) or Section 368(a)(1)(F) of the
Internal Revenue Code of 1986, as amended, and both the Arrow Portfolio and the
Arch Portfolio will be considered "a party to the reorganization" within the
meaning of Section 368(b) of the Code; (ii) no gain or loss will be recognized
by the Arrow Portfolios as a result of such transactions; (iii) no gain or loss
will be recognized by the Arch Portfolios as a result of such transactions; (iv)
no gain or loss will be recognized by the Shareholders of any Arrow Portfolio on
the distribution to them of Investor A Shares of the     

                                       18

<PAGE>

corresponding Arch Portfolio in exchange for their shares of the Arrow
Portfolio; (v) the aggregate basis of the Investor A Shares of an Arch Portfolio
received by a Shareholder of an Arrow Portfolio will be the same as the
aggregate basis of the Shareholder's Arrow Portfolio shares immediately prior to
the Reorganization; (vi) the basis of each Arch Portfolio in the assets of the
corresponding Arrow Portfolio received pursuant to the Reorganization will be
the same as the basis of the assets in the hands of the Arrow Portfolio
immediately before the Reorganization; (vii) a Shareholder's holding period for
Investor A Shares of an Arch Portfolio will be determined by including the
period for which the Shareholder held the Arrow Portfolio shares exchanged
therefor, provided that the Shareholder held such Arrow Portfolio shares as a
capital asset; and (viii) each Arch Portfolio's holding period with respect to
the assets received in the Reorganization will include the period for which such
assets were held by the corresponding Arrow Portfolio.

     Arch and Arrow have not sought a tax ruling from the Internal Revenue
Service ("IRS"), but are acting in reliance upon the opinion of counsel
discussed in the previous paragraph. That opinion is not binding on the IRS and
does not preclude the IRS from adopting a contrary position. Shareholders should
consult their own advisers concerning the potential tax consequences to them,
including state and local income taxes.

               COMPARISON OF INVESTMENT POLICIES AND RISK FACTORS

     The investment objectives and policies of the Reorganizing Portfolios are,
in many respects, similar to those of the corresponding Existing Arch
Portfolios. There are, however, certain differences. The following discussion
summarizes some of the more significant similarities and differences in the
investment policies and risk factors of the Reorganizing Portfolios and their
corresponding Existing Arch Portfolios and is qualified in its entirety by the
discussion elsewhere herein, and in the Prospectuses and Statements of
Additional Information of the Reorganizing Portfolios and the Existing Arch
Portfolios incorporated herein by reference.

INVESTMENT POLICIES AND RISK -- GENERAL

     The investment objective of each of the Reorganizing Portfolios and of each
of the Existing Arch Portfolios is fundamental, meaning that it may not be
changed without the vote of the holders of a majority of the Portfolio's
outstanding shares (as defined in the 1940 Act). Unless otherwise indicated, the
investment policies of the Reorganizing Portfolios and Existing Arch Portfolios
are not fundamental and may be changed by the respective Boards of Trustees or
Directors.

ARROW FIXED INCOME PORTFOLIO AND ARCH GOVERNMENT & CORPORATE BOND PORTFOLIO

     The investment policies of the Portfolios are similar, but not identical.
Both Portfolios invest at least 65% of their respective assets (under normal
conditions, in the case of the Arrow Fixed Income Portfolio) in U.S. Government
and investment grade corporate debt securities. Both Portfolios will only invest
in investment grade securities, i.e. securities rated at the time of purchase in
the four highest rating categories assigned by a rating agency or, if unrated,
determined by MVA to be of comparable quality, although the Arch Government &
Corporate Bond Portfolio must (i) invest a minimum of 65% of its assets in
securities rated in the three highest rating categories assigned by a rating
agency or, if unrated, determined by MVA to be of comparable quality, and (ii)
maintain a dollar-weighted average portfolio quality of at least "A" or higher.
Debt securities with the lowest investment grade rating do not have outstanding
investment characteristics and may have speculative characteristics as well.

                                       19

<PAGE>

     The debt securities in which each Portfolio may invest include fixed and
variable rate bonds, debentures, notes, and securities convertible into or
exchangeable for common stock (the Arrow Portfolio may also invest in securities
convertible into or exchangeable for preferred stock). The Arrow Fixed Income
Portfolio may also invest in preferred stock and units, which are debt
securities with stock or warrants to buy stock attached.

     The Arrow Fixed Income Portfolio may invest up to 10% of its assets in the
debt securities of foreign issuers. Such securities include the securities of
foreign governments, foreign governmental agencies or supranational
organizations or investment grade debt securities of foreign corporations. The
Arch Government & Corporate Bond Portfolio may invest up to 10% of its total
assets in dollar-denominated debt obligations of foreign issuers, either
directly or indirectly through ADRs and EDRs. Investments in securities of
foreign issuers, whether made directly or indirectly, carry certain risks not
ordinarily associated with investments in securities of foreign issuers. Such
risks include future political and economic developments and the possible
imposition of exchange controls or other foreign governmental laws or
restrictions. In addition, with respect to certain countries, there is the
possibility of expropriation of assets, confiscatory taxation, political or
social instability or diplomatic developments which could adversely affect
investments in those countries.

     The Arrow Fixed Income Portfolio may invest in mortgage-related
asset-backed securities, including collateralized mortgage obligations ("CMOs"),
rated in one of the three highest rating categories assigned by one or more
rating agencies or determined to be of comparable quality by MVA. The Arch
Government & Corporate Bond Portfolio may invest in investment grade
mortgage-related asset-backed securities, including CMOs, as well as
non-mortgage-related asset-backed securities, although investments in
non-mortgage-related asset-backed securities will not exceed 25% of the
Portfolio's total assets at the time of purchase. The average life of
asset-backed securities varies with the underlying instruments or assets and
market conditions, which in the case of mortgages have maximum maturities of
forty years. The average life of a mortgage-backed instrument, in particular, is
likely to be substantially less than the original maturity of the mortgages
underlying the securities as the result of unscheduled principal payments and
mortgage prepayments. The relationship between mortgage prepayment and interest
rates may give some high-yielding mortgage-backed securities less potential for
growth in value than conventional bonds with comparable maturities. In addition,
in periods of falling interest rates, the rate of mortgage prepayments tends to
increase. During such periods, the reinvestment of prepayment proceeds by a
Portfolio will generally be at lower rates than the rates that were carried by
the obligations that have been prepaid. When interest rates rise, the value of
an asset-backed security generally will decline; however, when interest rates
decline, the value of an asset-backed security with prepayment features may not
increase as much as that of other fixed-income securities. Because of these and
other reasons, an asset-backed security's total return may be difficult to
predict. The collateral supporting non-mortgage-related asset-backed securities
is of shorter maturity than mortgage loans and is less likely to experience
substantial prepayments. Non-mortgage-related asset-backed securities involve
certain risks that are not presented by mortgage-backed securities arising
primarily from the nature of the underlying assets (i.e., credit card and
automobile loan receivables as opposed to real estate mortgages). For example,
credit card receivables are generally unsecured and the repossession of
automobiles and other personal property upon the default of the debtor may be
difficult or impracticable in some cases. The Arch Government & Corporate Bond
Portfolio may also invest in first mortgage loans, income participation loans
and participations in certificates of pools of mortgages.

                                       20

     Each Portfolio may purchase put and call options listed on a national
securities exchange and issued by the Options Clearing Corporation, provided,
however, that the Arch Government & Corporate Bond Portfolio will not invest
more than 10% of its net assets in such options. Purchasing options is a
specialized investment technique which entails a substantial risk of a complete
loss of the amounts paid as premiums to the option writer. Each Portfolio may
also write covered call options (and covered put options in the case of the
Arrow Fixed Income Portfolio) listed on a national securities exchange and
issued by the Options Clearing Corporation, limited in amount with respect to
the Arch Government & Corporate Bond Portfolio to not more than 20% of the value
of the Portfolio's net assets. The Arrow Fixed Income Portfolio may also
purchase and write unlisted over-the-counter options which are not subject to
the protections afforded purchasers of listed options by the Options Clearing
Corporation, which performs the obligations of its members which fail to perform
them in connection with the purchase or sale of options.

     Each Portfolio may purchase and sell futures contracts and options on
futures contracts as a hedge against anticipated changes in interest rates or
market conditions. Neither Portfolio will purchase or sell futures contracts or
related options for hedging purposes if, immediately after purchase, the
aggregate initial margin deposits and premiums paid by a Portfolio on its open
futures and options positions exceeds 5% of the Portfolio's total assets. When
futures and related options are used as a hedging device, there is a risk that
the prices of the securities subject to the futures contract may not correlate
with the prices of a Portfolio's investment securities. This may cause the
futures contract and any related options to react differently than the
Portfolio's investment securities to market changes.

     The Arch Government & Corporate Bond Portfolio may hold as a temporary
defensive measure up to 100% of its total assets in cash and short-term
obligations (having remaining maturities of 12 months or less) at such time and
in such proportions as, in the opinion of MVA, prevailing market or economic
conditions warrant. Such short-term obligations may include commercial paper,
bankers acceptances, certificates of deposit, demand and time deposits of
domestic and foreign banks and savings and loan associations, and obligations
issued or guaranteed by the U.S. Government or its agencies or
instrumentalities. The Arrow Fixed Income Portfolio may invest in commercial
paper rated in the top two rating categories assigned by one or more rating
agencies; time and savings deposits (including certificates of deposit) in
certain domestic banks and certificates of deposit and other time deposits
issued by the foreign branches of such domestic banks; and obligations issued or
guaranteed by the U.S. Government or its agencies or instrumentalities.

     Each Portfolio may purchase "stripped" securities limited, with respect to
the Arch Government & Corporate Bond Portfolio, to stripped U.S. Treasury and
agency obligations. Stripped securities are issued at a discount to their face
value and may exhibit greater price volatility than ordinary debt securities
because of the manner in which their principal and interest are returned to
investors.

     Each Portfolio may purchase "when-issued" securities, and the Arch
Government & Corporate Bond Portfolio may also purchase and sell securities on a
forward commitment or delayed settlement basis. Both Portfolios may enter into
repurchase and reverse repurchase agreement transactions, lend their portfolio
securities and invest in the securities of other investment companies. Neither
Portfolio will invest more than 15% of the value of its net assets in illiquid
securities.

                                       21

<PAGE>

ARROW MUNICIPAL INCOME PORTFOLIO AND ARCH NATIONAL MUNICIPAL BOND PORTFOLIO

     The Portfolios have similar, but not identical, investment policies. As a
matter of fundamental policy, each Portfolio invests at least 80% of its total
assets in municipal securities, primarily bonds (at least 65% under normal
market conditions) with respect to the Arch National Municipal Bond Portfolio.
Each Portfolio purchases only investment grade municipal securities, i.e.
securities rated in the top four rating categories assigned by one or more
rating agencies or, if unrated, determined by MVA to be of comparable quality,
provided, however, that (i) the Arch National Municipal Bond Portfolio will
invest, under normal conditions, at least 65% of its assets in municipal
securities that are rated at the time of purchase in one of the three highest
rating categories assigned by one or more rating agencies or, if unrated,
determined by MVA to be of comparable quality, and (ii) the Arrow Municipal
Income Portfolio may invest in short-term municipal securities rated in the
highest rating category by one or more rating agencies.

   
     The Arch National Municipal Bond Portfolio may invest 25% or more of its
net assets in (i) municipal securities whose issuers are in the same state, (ii)
municipal securities the interest on which is paid solely from revenues of
similar projects, and (iii) private activity bonds. The Arrow Municipal Income
Portfolio may invest more than 25% of the value of its assets in industrial
development bonds. Both Portfolios may invest in participation interests (the
Arch Portfolio may also invest in other tax-exempt derivative instruments) and
variable and floating rate municipal securities.     

   
     During temporary defensive periods, the Arch National Municipal Bond
Portfolio (i) may invest in taxable obligations, such as obligations of the U.S.
Government, its agencies and instrumentalities, including "stripped securities,"
and debt securities (including commercial paper) of issuers having, at the time
of purchase, a quality rating within the two highest rating categories assigned
by one or more rating agencies, and (ii) may hold without limit uninvested cash
reserves which do not earn income pending investment.     

     Unlike the Arch National Municipal Bond Portfolio, the Arrow Municipal
Income Portfolio may purchase listed and unlisted put and call options and write
listed and unlisted covered call options and covered put options. See
"Comparison of Investment Policies and Risk Factors -- Arrow Fixed Income
Portfolio and Arch Government & Corporate Bond Portfolio" above.

     The Arrow Municipal Income Portfolio may enter into repurchase agreements
and reverse repurchase agreements, whereas the Arch National Municipal Bond
Portfolio may not. Each Portfolio may purchase "when-issued" securities and the
Arch National Municipal Bond Portfolio may also purchase and sell securities on
a forward commitment or delayed settlement basis and enter into stand-by
commitments. Each Portfolio may lend its portfolio securities and invest in the
securities of other investment companies. While both Portfolios may invest up to
15% of their respective net assets in illiquid securities, the Arrow Municipal
Income Portfolio may only invest up to 10% of its net assets in restricted
municipal securities.

INVESTMENT LIMITATIONS

     Neither the Reorganizing Portfolios nor the Existing Arch Portfolios may
change their fundamental investment limitations without the affirmative vote of
the holders of a majority of the outstanding shares (as defined in the 1940 Act)
of the particular Reorganizing Portfolio or Existing Arch Portfolio. The
investment limitations of the Reorganizing Portfolios and the corresponding
Existing Arch Portfolios are similar, but not identical.

                                       22

<PAGE>

     Each of the Reorganizing Portfolios and each of the Existing Arch
Portfolios is a "diversified" investment portfolio and, therefore, has a
fundamental policy limiting investments in securities of any one issuer (other
than cash, cash items or securities issued by the U.S. Government, its agencies
and instrumentalities and, with respect to the Reorganizing Portfolios,
repurchase agreements collateralized by such securities) to 5% of the value of a
Portfolio's total assets, except that up to 25% of the value of a Portfolio's
total assets may be invested without regard to this 5% limitation. In addition,
none of the Reorganizing Portfolios or the Existing Arch Portfolios may acquire
more than 10% of the outstanding voting securities of any one issuer, except
that the Existing Arch Portfolios may invest up to 25% of their respective total
assets without regard to such 10% limitation.

     The Reorganizing Portfolios may not issue senior securities, except that
each Portfolio may borrow money directly or through reverse repurchase
agreements in amounts up to one-third the value of its total assets, including
the amount borrowed, for temporary purposes. The Existing Arch Portfolios may
not borrow money or issue senior securities, except that each Portfolio may
borrow from banks and the Arch Government & Corporate Bond Portfolio may enter
into reverse repurchase agreements for temporary purposes in amounts not in
excess of 10% of the Portfolio's total assets at the time of such borrowing.
Neither a Reorganizing Portfolio nor an Existing Arch Portfolio will purchase
securities while its borrowings, including reverse repurchase agreements, exceed
5% of the total assets of such Portfolio.

     The Reorganizing Portfolios and the Existing Arch Portfolios may mortgage,
pledge or hypothecate their assets only to secure permitted indebtedness, and
then may only pledge assets having a market value not exceeding the lesser of
the dollar amounts borrowed or 15%, in the case of the Reorganizing Portfolios,
or 10% in the case of the Existing Arch Portfolios, of the value of the
Portfolio's total assets.

     The investment limitations described in the foregoing paragraphs regarding
diversification and borrowing are fundamental with respect to both the
Reorganizing Portfolios and Existing Arch Portfolios. The limitation with
respect to pledging portfolio assets is fundamental as to the Existing Arch
Portfolios, but not fundamental as to the Reorganizing Portfolios.

   
     Neither the Reorganizing Portfolios nor the Existing Arch Portfolios may
make loans, except that: (i) the Reorganizing Portfolios may lend portfolio
securities up to one-third of the value of their respective total assets; (ii)
the Reorganizing Portfolios may purchase or hold certain debt instruments and
may enter into repurchase agreements; and (iii) each Existing Arch Portfolio may
purchase or hold debt instruments, lend portfolio securities, and, except for
the Arch National Municipal Bond Portfolio, enter into repurchase agreements.
The foregoing limitations on securities lending are fundamental limitations for
both the Reorganizing Portfolios and the Existing Arch Portfolios.
    

   
     The Reorganizing Portfolios and the Existing Arch Portfolios may not invest
25% or more of the value of their respective total assets in the securities of
one or more issuers conducting their principal business activities in the same
industry, provided that (a) with respect to the Reorganizing Funds, (i) there is
no limitation concerning cash, certain money market instruments, or securities
issued or guaranteed by the U.S. Government, its agencies, or instrumentalities
and repurchase agreements collateralized by such securities and (ii) no more
than 25% of the Arrow Municipal Income Portfolio's total assets may be invested
in a governmental subdivision of any one state, territory or possession of the
United States; (b) with respect to the Arch Government & Corporate Bond
Portfolio, (i) there is no limitation with respect to obligations issued or
guaranteed by the U.S. Government, its agencies or instrumentalities; (ii)
wholly-owned finance companies     

                                       23

<PAGE>

will be considered to be in the industry of their parents if their activities
are primarily related to financing the activities of their parents; and (iii)
utilities will be divided according to their services (for example, gas, gas
transmission, electric and gas, electric and telephone will each be considered a
separate industry); and (c) with respect to the Arch National Municipal Bond
Portfolio, there is no limitation with respect to obligations issued or
guaranteed by the U.S. Government, any state, territory or possession of the
U.S. Government, the District of Columbia, or any of their authorities,
agencies, instrumentalities or political subdivisions. The foregoing investment
limitations with respect to industry concentration of investments are
fundamental investment limitations as to both the Reorganizing Portfolios and
the Existing Arch Portfolios.

     Neither the Reorganizing Portfolios nor the Existing Arch Portfolios may
purchase or sell real estate, except that the Portfolios may purchase securities
of issuers which deal in real estate and may purchase securities which are
secured by interests in real estate. The foregoing limitations on investments in
real estate are fundamental as to both the Reorganizing Portfolios and the
Existing Arch Portfolios.

   
     Neither the Reorganizing Portfolios nor the Existing Arch Portfolios may
act as an underwriter of securities within the meaning of the Securities Act of
1933, except to the extent that the purchase of obligations directly from the
issuer thereof, or the disposition of securities, in accordance with a
Portfolio's investment objective, policies and limitations may be deemed to be
underwriting. The foregoing limitations on underwriting are fundamental as to
both the Reorganizing Portfolios and Existing Arch Portfolios.
    

     The Existing Arch Portfolios may not purchase securities of companies for
the purpose of exercising control. The foregoing limitation is fundamental as to
such Portfolios. The Reorganizing Portfolios are not subject to a similar
limitation.

   
     Neither the Reorganizing Portfolios nor the Existing Arch Portfolios may
purchase securities on margin, make short sales of securities or maintain a
short position, except that (i) each Portfolio may obtain such short-term
credits as may be necessary for the clearance of purchases and sales of
portfolio securities, (ii) this limitation shall not apply to the Arch
Government & Corporate Bond Portfolio's transactions in options and futures
contracts and related options, and (iii) with respect to the Arrow Fixed Income
Portfolio, the deposit or payment of initial or variation margin in connection
with financial futures contracts or related options transactions is not
considered the purchase of a security on margin. The foregoing limitations are
fundamental as to both the Reorganizing Portfolios and the Existing Arch
Portfolios.     

     The Reorganizing Portfolios may not purchase or sell commodities, commodity
contracts, or commodities futures contracts. The Existing Arch Portfolios may
not purchase or sell commodities contracts, or invest in oil, gas or mineral
exploration or development programs.

PURCHASE AND REDEMPTION INFORMATION, EXCHANGE PRIVILEGES, DISTRIBUTION AND
PRICING

   
     The purchase, redemption, exchange privileges and distribution policies of
the Arrow Portfolios and the Arch Portfolios are discussed below in Appendix III
to this Combined Proxy Statement/Prospectus.     

OTHER INFORMATION

   
     Arrow and Arch are registered as open-end, series, management investment
companies under the 1940 Act. Currently, Arrow offers four investment portfolios
and Arch offers eighteen investment portfolios.     

                                       24

<PAGE>

     Arrow is organized as a Massachusetts business trust and is subject to the
provisions of its Declaration of Trust and By-Laws. Arch is organized as a
Maryland corporation and is subject to the provisions of its Articles of
Incorporation and By-Laws. Although the rights of shareholders of a Maryland
corporation vary in certain respects from the rights of shareholders of a
Massachusetts business trust, the attributes of a share of common stock in Arch
are comparable to those of a share of beneficial interest in Arrow. Shares of
both Arrow and Arch: (i) are entitled to one vote for each full share held and a
proportionate fractional vote for each fractional share held; (ii) will vote in
the aggregate and not by class except as otherwise expressly required by law or
when class voting is permitted by the respective Boards of Trustees or
Directors; and (iii) are entitled to participate equally in the dividends and
distributions that are declared with respect to a particular class and in the
net distributable assets of such class on liquidation. Shares of the Arch
Portfolios have a par value of $.001, while the shares of the Arrow Portfolios
have no par value. In addition, shares of the Arrow Portfolios and Arch
Portfolios have no preemptive rights and only such conversion and exchange
rights as the respective Boards of Trustees or Directors may grant in their
discretion. When issued for payment as described in their respective
Prospectuses, Arrow Portfolio shares and Arch Portfolio shares are validly
issued, fully paid and non-assessable by such entities except as required under
Massachusetts law with respect to Arrow, and Maryland law with respect to Arch.
Arch is not required under Maryland General Corporation Law to hold annual
shareholder meetings and intends to do so only if required by the 1940 Act.
Shareholders have the right to remove Directors. To the extent required by law,
Arch will assist in shareholder communications in such matters.

     The foregoing is only a summary. Shareholders may obtain copies of the
Declaration of Trust and By-Laws of Arrow and the Articles of Incorporation and
By-laws of Arch upon written request at the addresses shown on the cover page of
this Combined Proxy Statement/Prospectus.

                     INFORMATION RELATING TO VOTING MATTERS

   
     GENERAL INFORMATION. This Combined Proxy Statement/Prospectus is being
furnished in connection with the solicitation of proxies by Arrow's Board of
Trustees in connection with the Meeting. It is expected that the solicitation of
proxies will be primarily by mail. Officers and service contractors of Arrow may
also solicit proxies by telephone, telegraph, facsimile or personal interview.
Any shareholder giving a proxy may revoke it at any time before it is exercised
by submitting to Arrow a written notice of revocation or a subsequently executed
proxy or by attending the Meeting and voting in person.
    

   
     Only shareholders of record at the close of business on September 12, 1997
will be entitled to vote at the Meeting. On that date there were outstanding and
entitled to be voted 2,731,914.3010 shares of the Arrow Fixed Income Portfolio,
1,261,072.2490 shares of the Arrow Municipal Income Portfolio, and
3,629,043.7010 shares of the Arrow Equity Portfolio. Each share or fraction
thereof is entitled to one vote or fraction thereof, and all shares will vote
separately by Portfolio.     

   
     At September 12, 1997, Mercantile Bank owned of record with the power to
vote approximately 96.42% of the outstanding shares of the Arrow Portfolios on
behalf of its customers. Arrow and Arch have been advised by Mercantile Bank
that it intends to vote the shares of each Arrow Portfolio over which it has
voting power "FOR" the Reorganization.     

                                       25

<PAGE>

     If the accompanying proxy is executed and returned in time for the Meeting,
the shares covered thereby will be voted in accordance with the proxy on all
matters that may properly come before the Meeting or any adjournment thereof.
For information on adjournment of the meeting, see "Quorum" below.

   
     SHAREHOLDER AND BOARD APPROVALS. The Reorganization Agreement (and the
transactions contemplated thereby) is being submitted for approval at the
Meeting by the holders of a majority of the outstanding shares of the Arrow
Fixed Income Portfolio, the Arrow Municipal Income Portfolio and the Arrow
Equity Portfolio in accordance with the provisions of Arrow's Declaration of
Trust and the requirements of the 1940 Act. The term "majority of the
outstanding shares" of an Arrow Portfolio as used herein means the lesser of (a)
67% of the shares of the particular Arrow Portfolio present at the Meeting if
the holders of more than 50% of the outstanding shares of the Arrow Portfolio
are present in person or by proxy, or (b) more than 50% of the outstanding
shares of such Arrow Portfolio.     

     In tallying shareholder votes, abstentions and broker non-votes (i.e.,
proxies sent in by brokers and other nominees that cannot be voted on a proposal
because instructions have not been received from the beneficial owners) will be
counted for purposes of determining whether or not a quorum is present for
purposes of convening the meeting. On the Reorganization proposal, abstentions
and broker non-votes will be considered to be a vote against the Reorganization
proposal.

     The approval of the Reorganization by the shareholders of the corresponding
Arch Portfolios is not being solicited because their approval or consent is not
necessary for the Reorganization to be consummated.

     At September 12, 1997, the name, address and share ownership of the persons
who owned of record 5% or more of the outstanding shares of the Reorganizing
Portfolios and the percentage of Investor A Shares of the corresponding Existing
Arch Portfolios that would be owned by those persons upon the consummation of
the Reorganizing Portfolios Transaction based on their holdings on that date are
as follows:

     APPRAISAL RIGHTS. Shareholders are not entitled to any rights of share
appraisal under Arrow's Declaration of Trust or under the laws of the
Commonwealth of Massachusetts in connection with the Reorganization.
Shareholders have, however, the right to redeem from Arrow their Arrow Portfolio
shares at net asset value until the effective time of the Reorganization with
respect to each Arrow Portfolio, and thereafter shareholders may redeem the
Investor A Shares of the Arch Portfolios acquired by them in the Reorganization
at net asset value.     

   
     QUORUM. In the event that a quorum is not present at the Meeting, or in the
event that a quorum is present at the Meeting but sufficient votes to approve
the Reorganization Agreement and the transactions contemplated thereby are not
received, the persons named as proxies may propose one or more adjournments of
the Meeting to permit further solicitation of proxies. Any such adjournment will
require the affirmative vote of a majority of those shares affected by the
adjournment that are represented at the Meeting in person or by proxy. If a
quorum is present, the persons named as proxies will vote those proxies which
they are entitled to vote FOR the Reorganization Agreement, in favor of such
adjournments, and will vote those proxies required to be voted AGAINST such
proposal against any adjournment. A shareholder vote may be taken with respect
to one or more Arrow Portfolios prior to any such adjournment if sufficient
votes have been received for     

                                       28

<PAGE>

approval with respect to any such Arrow Portfolio. A quorum is constituted with
respect to an Arrow Portfolio by the presence in person or by proxy of the
holders of more than 50% of the outstanding shares of the Portfolio entitled to
vote at the Meeting. Arrow proxies properly executed and marked with a negative
vote or an abstention will be considered to be present at the Meeting for the
purposes of determining the existence of a quorum for the transaction of
business.

     ANNUAL MEETINGS. Arch does not presently intend to hold annual meetings of
shareholders for the election of directors and other business unless and until
such time as less than a majority of the directors holding office have been
elected by the shareholders, at which time the directors then in office will
call a shareholders' meeting for the election of directors. Shareholders have
the right to call a meeting of shareholders to consider the removal of one or
more directors or for other matters and such meetings will be called when
requested in writing by the holders of record of 25% or more of Arch's
outstanding shares of common stock. To the extent required by law, Arch will
assist in shareholder communications on such matters.

                      AGREEMENT AND PLAN OF REORGANIZATION

   
     AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") made as of September
12, 1997 between THE ARCH FUND(R), INC., a Maryland corporation ("Arch"), and
ARROW FUNDS, a Massachusetts business trust ("Arrow").     

     WHEREAS, Arrow currently consists of four investment portfolios, i.e. the
Arrow Government Money Market Portfolio, the Arrow Fixed Income Portfolio, the
Arrow Municipal Income Portfolio and the Arrow Equity Portfolio;

     WHEREAS, the parties intend that substantially all of the assets and known
liabilities of the Arrow Fixed Income Portfolio, the Arrow Municipal Income
Portfolio and the Arrow Equity Portfolio as of the Effective Time of the
Reorganization (as defined in Article III) with respect to each such Portfolio
be transferred to, and be acquired and assumed by, certain Arch portfolios in
exchange for Investor A Shares of the Arch portfolios which shall thereafter be
distributed by Arrow to the holders of the shares of its portfolios, all as
described in this Agreement (the "Reorganization");

     WHEREAS, the parties intend that one of the Arch portfolios, the ARCH
Growth Equity Portfolio, will have nominal assets and liabilities before the
Reorganization and will continue the investment operations of the Arrow Equity
Portfolio (the "Continuing Portfolio") after the Reorganization;

     WHEREAS, the parties intend that substantially all of the assets and known
liabilities of the Arrow Fixed Income Portfolio and the Arrow Municipal Income
Portfolio (the "Reorganizing Portfolios" and, together with the Continuing
Portfolio, the "Acquired Portfolios") shall be acquired and assumed by the Arch
Government & Corporate Bond Portfolio and the Arch National Municipal Bond
Portfolio, respectively;

     WHEREAS, the parties intend that the Reorganization with respect to the
Reorganizing Portfolios will occur on a date that is prior to the Reorganization
with respect to the Continuing Portfolio;

     WHEREAS, the parties have been advised that the shareholders of the Arrow
Government Money Market Portfolio will redeem their shares in that portfolio
prior to the Effective Time of the Reorganization with respect to the
Reorganizing Portfolios;

     WHEREAS, the parties intend that the transfers of assets, assumptions of
liabilities, and distributions of Investor A Shares be treated as tax-free
reorganizations under Section 368(a)(1)(C), (D) or (F) of the Internal Revenue
Code of 1986, as amended (the "Code"); and

     WHEREAS, the parties intend that in connection with the Reorganization each
of the Acquired Portfolios shall be terminated and Arrow shall be deregistered
as an investment company and dissolved under state law as described in this
Agreement.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
hereinafter set forth and subject to the terms and conditions hereof, and
intending to be legally bound hereby, Arch and Arrow agree as follows:

     I.  TRANSFER OF ASSETS OF ARROW FUNDS.

     1.01 At the Effective Time of the Reorganization (as defined in Article
III) with respect to each of the Acquired Portfolios, all property of every
description, and all interests, rights, privileges and powers of such

                                       I-3

<PAGE>

Acquired Portfolio other than cash in an amount necessary to pay any unpaid
dividends and distributions as provided in Article IV, Section 4.01(h) (such
assets, the "Acquired Portfolio Assets"), shall be transferred and conveyed by
such Acquired Portfolio to Arch on behalf of one of its portfolios as set forth
in Article I, Section 1.02 (each, an "Acquiring Portfolio"), and shall be
accepted by Arch on behalf of such Acquiring Portfolio, and Arch, on behalf of
such Acquiring Portfolio, shall assume all known liabilities, whether accrued,
absolute, contingent or otherwise, of such Acquired Portfolio reflected in the
calculation of such Acquired Portfolio's net asset value (the "Acquired
Portfolio Liabilities"), so that at and after the Effective Time of the
Reorganization with respect to such Acquired Portfolio: (i) all assets of such
Acquired Portfolio shall become and be the assets of its Acquiring Portfolio;
and (ii) all known liabilities of such Acquired Portfolio reflected as such in
the calculation of such Acquired Portfolio's net asset value shall attach to its
Acquiring Portfolio as aforesaid and may thenceforth be enforced against such
Acquiring Portfolio to the extent as if the same had been incurred by it.
Without limiting the generality of the foregoing, the Acquired Portfolio Assets
shall include all property and assets of any nature whatsoever, including,
without limitation, all cash, cash equivalents, securities, claims and
receivables (including dividend and interest receivables) owned by an Acquired
Portfolio, and any deferred or prepaid expenses shown as an asset on an Acquired
Portfolio's books, at the Effective Time of the Reorganization of such Acquired
Portfolio, and all good will, all other intangible property and all books and
records belonging to an Acquired Portfolio. Recourse by any person for the
Acquired Portfolio Liabilities assumed by an Acquiring Portfolio shall, at and
after the Effective Time of the Reorganization of such Acquired Portfolio, be
limited to such Acquiring Portfolio.

     1.02 The assets of each Acquired Portfolio shall be acquired by the
Acquiring Portfolio identified below opposite its name:

                                                   D Common Stock)
Municipal Income Portfolio                       National Municipal Bond Portfolio (Class N
                                                   Common Stock)

                                                   Stock)
</TABLE>

     1.03 In exchange for the transfer of the Acquired Portfolio Assets and the
assumption of the Acquired Portfolio Liabilities, Arch shall simultaneously
issue at the applicable Effective Time of the Reorganization to each Acquired
Portfolio a number of full and fractional (to the third decimal place) Investor
A Shares of the Acquiring Portfolio specified in Article I, Section 1.02, all
determined and adjusted as provided in this Agreement. The number of Investor A
Shares of each Acquiring Portfolio so issued will have an aggregate net asset
value equal to the net value of the Acquired Portfolio Assets that are
represented by the shares of the Acquired Portfolio, the holders of which shall
receive Investor A Shares of the Acquiring Portfolio, as specified in Article I,
Section 1.02, all determined and adjusted as provided in this Agreement.

     1.04 The net asset value of the Investor A Shares of the Acquiring
Portfolios and the net asset value of the shares of the Acquired Portfolios
shall be determined as of the applicable Effective Time of the Reorganization
with respect to each Acquired Portfolio.

     1.05 The net asset value of the Investor A Shares of each Acquiring
Portfolio shall be computed in the manner set forth in such Acquiring
Portfolio's then current prospectuses under the Securities Act of 1933, as

                                       I-4

<PAGE>

amended (the "1933 Act"). In determining the value of the securities transferred
by the Acquired Portfolios to the Acquiring Portfolios, each security shall be
priced in accordance with the policies and procedures of Arch described in its
then current prospectuses and statements of additional information and adopted
by Arch's Board of Directors. For such purposes, price quotations and the
security characteristics relating to establishing such quotations shall be
determined by Arch, such determination being subject to the approval of Arrow,
and shall be subject to adjustment by the amount, if any, agreed to by the
parties hereto.

     II. LIQUIDATING DISTRIBUTIONS AND TERMINATION OF ARROW. Immediately after
the Effective Time of the Reorganization with respect to each Acquired
Portfolio, such Acquired Portfolio shall distribute in complete liquidation pro
rata to the record holders of its shares at the applicable Effective Time of the
Reorganization the Investor A Shares of the Acquiring Portfolio identified in
Article I, Section 1.02, to be received by the record holders of the shares of
such Acquired Portfolio. In addition, each shareholder of record of an Acquired
Portfolio shall have the right to receive any unpaid dividends or other
distributions which were declared before the applicable Effective Time of the
Reorganization with respect to the shares of such Acquired Portfolio that are
held by the shareholder at the applicable Effective Time of the Reorganization.
In accordance with instructions it receives from Arrow, Arch shall record on its
books the ownership of Investor A Shares of each Acquiring Portfolio by the
record holders of the shares of the Acquired Portfolio identified in Article I,
Section 1.02. No redemption or repurchase of any Acquiring Portfolio shares
credited to Arrow shareholders of record with respect to the Acquired Portfolio
shares represented by share certificates shall be permitted until such
certificates have been surrendered to Arch's transfer agent for cancellation.
All of the issued and outstanding shares of each Acquired Portfolio shall be
cancelled on the books of Arrow at the Effective Time of the Reorganization of
such Acquired Portfolio and shall thereafter represent only the right to receive
the Investor A Shares of the Acquiring Portfolio identified in Article I,
Section 1.02, following which the Acquired Portfolio's transfer books shall be
closed permanently. As soon as practicable after the Effective Time of the
Reorganization with respect to the Continuing Fund, Arrow shall make all filings
and take all other steps as shall be necessary and proper to effect its complete
dissolution, and shall file an application pursuant to Section 8(f) of the
Investment Company Act of 1940, as amended (the "1940 Act") for an order
declaring that it has ceased to be an investment company. After the Effective
Time of the Reorganization with respect to the Continuing Fund, Arrow shall not
conduct any business except in connection with its liquidation, dissolution, and
deregistration.

     III. EFFECTIVE TIMES OF THE REORGANIZATION. The Effective Time of the
Reorganization with respect to the Reorganizing Portfolios shall be 4:00 p.m.,
Eastern Time, on November 14, 1997, or on such other date as may be agreed to in
writing by the duly authorized officers of both parties hereto. The Effective
Time of the Reorganization with respect to the Continuing Portfolio shall be
4:00 p.m., Eastern Time, on November 21, 1997, or on such other date as may be
agreed to in writing by the duly authorized officers of both parties hereto.

     the period from said date to and including the Effective Time of the

                                       I-6

     Reorganization applicable to the Reorganizing Portfolios (computed without
     regard to any deduction for dividends paid), and all of its net capital
     gain, if any, realized in such taxable year and period.

     Portfolio and, upon delivery and payment for the Acquired Portfolio Assets
     as contemplated herein, an Acquiring Portfolio shall acquire good and
     marketable title thereto, free and clear of all liens and encumbrances, and
     subject to no restrictions on the ownership or transfer thereof (except as
     imposed by federal or state securities laws).

          4.01(l) No consent, approval, authorization or order of any court or
     governmental authority is required for the consummation by Arrow of the

     Acquired Portfolio has any preemptive right of subscription or purchase in
     respect of such shares.

     Acquiring Portfolio to be received in the transactions contemplated herein,

     restore such compliance as soon as is reasonably practicable.

Reorganization applicable to the Reorganizing Portfolios and as a condition to
the Reorganization, Arrow shall hold a meeting of the shareholders of the
Acquired Portfolios for the purpose of considering and voting upon:

        Portfolio, as set forth in Article I, Section 1.02.

the shareholders of the Acquired Portfolios shall constitute the waiver of the
application of any fundamental policy of such Acquired Portfolios that might be

Reorganization as described, and such policies, if any, shall be deemed to have
been amended accordingly.

                            MANAGEMENT'S DISCUSSION
                              OF FUND PERFORMANCE

THE ARCH NATIONAL MUNICIPAL BOND PORTFOLIO

     Q.  How will you manage this new Portfolio?

     A. The Fund was launched on November 18, 1996, and invests in high-quality
municipal securities in various municipalities across the country. It will
maintain an average credit quality of around AA1 under present conditions. One
reason for this is that the municipal market generally has not paid much in
additional yield to investors who take on the added risk in lower-quality
issues. The Portfolio's average maturity initially will be approximately ten
years. However, that will change as market conditions warrant. The Portfolio's
income may be subject to certain state and local taxes and, depending on an
investor's tax status, the federal alternative minimum tax.

   
THE ARCH GOVERNMENT & CORPORATE BOND PORTFOLIO
    

[CHART 1]                                                              [CHART 2]

     The ARCH Government & Corporate Bond Portfolio is measured against the
Lehman Brothers Aggregate Bond Index, an unmanaged Index comprised of the Lehman
Brothers Government-Corporate Bond Index and two Lehman Brothers asset-backed
securities Indices. Investors cannot purchase the Index directly, although they
can invest in the underlying securities. The performance of the Index does not
reflect the deduction of expenses associated with a mutual fund, such as sales
charges, investment-management and fund-accounting fees. By contrast, the
performance of the Portfolio shown on the graph reflects the deduction of these
value-added services, as well as the deduction of a 4.50% sales charge on
Investor A shares and the applicable contingent deferred sales charge (CDSC) on
Investor B shares.

     Past performance is not predictive of future results. Investment return and
principal value will fluctuate, so that shares of a particular class, when
redeemed, may be worth more or less than their original cost.

                                      II-1

<PAGE>

     Investor B shares were initially offered on March 1, 1995. The performance
figures for Investor B shares for periods prior to such date represent the
performance for Investor A shares of the Portfolio, which has been restated to
reflect the contingent deferred sales charges payable by holders of Investor B
shares who redeem within six years of the date of purchase. Investor B shares
are also subject to distribution and service fees at a maximum annual rate of
1.00%. Had these distribution and service fees been reflected, performance would
have been reduced.

   
     Q.  What were the conditions in the taxable bond market during the 12
months ended November 30, 1996?
    

   
     A. The bond market has been volatile. The ten-year Treasury bond started
the period yielding 5.70%. That yield rose to 7.10% around mid-year, then fell
to 6.10%. Investors worried that the Federal Reserve would raise short-term
interest rates around the middle of the summer, because the economy had grown so
quickly in the first quarter. Then the Fed didn't do anything, and the fear
receded -- so bond prices started to rise again. We started to see another rally
toward the end of the 12-month period.     

   
     Q.  How did you structure the Portfolio to address those conditions?
    

   
     A. We invested about 75% of the Portfolio in Treasuries, with the rest in
mortgage-backed securities. Corporate bonds seemed very expensive to us, with
yields only about 12 one-hundredths of a percentage point higher than Treasury
yields -- and they have much more credit risk than Treasury or agency debt.
Thus, we used mortgage-backed issues instead of corporates to enhance the
Portfolio's yield.     

     The Portfolio's average maturity rose from 8.6 years to 10.8 years during
the period. We increased the maturity to take advantage of higher interest
rates. We implemented the change by selling some of our shorter Treasuries and
buying five- to ten-year mortgages. Such securities recently provided 0.75 to
1.25 percentage points of extra yield over Treasuries of comparable maturities.
In fact, we increased our Portfolio's mortgage-backed exposure from 26% to 35%,
currently*.

   
     Q.  How did you manage credit risk in the Portfolio?
    

   
     A. We currently have an average quality rating of AAA, the same rating that
we had at the beginning of the year. The Portfolio's holdings currently are
comprised almost entirely of United States Treasury and agency-guaranteed
mortgage debt. The Portfolio holds almost no corporate issues because we believe
that the small current yield advantage of corporates over Treasuries does not
justify corporate debt's additional credit risk.     

   
     Q.  Where are you finding the best values in the bond market?
    

   
     A. Mortgage-backed securities clearly offer the most value in our
securities universe. Our intent is to continue to increase the Portfolio's
mortgage exposure from the current 35% to the 40% to 45% level. Corporates will
remain on our watch list, and we will increase the Portfolio's corporate
exposure when their yields improve relative to yields on Treasury issues.*

     Q.  What is your outlook for the bond market and the Portfolio?
    

   
     A.  We're neutral on the market right now. We don't see anything
fundamental about the economy that would cause rates to rise or fall in the
immediate future. But we will pay close attention to the psychology of the
market, which can be a very different matter. People's expectations have a large
effect on the bond market, and we'll pay close attention to changes in those
expectations. That way, we'll be prepared to make changes in the Portfolio to
reflect such psychological factors.

THE ARROW FIXED INCOME PORTFOLIO
    

     The Arrow Fixed Income Portfolio had total net assets of $28.7 million as
of September 30, 1996. The fund had an average maturity of 11.5 years, with 36%
of the fund's assets invested in U.S. Treasury and Government Agency issues, and
57% invested in investment grade corporate bonds.

   
     Interest rates, after moving substantially higher in the first quarter of
the year, settled into a trading range environment in the second and third
quarter. Thirty-year Treasury securities spent most of the period fluctuating in
a range of 7.20% on the high side, to 6.70% on the low side, closing at a 6.92%
yield on September 30, 1996. Stronger economic data in the second quarter caused
yields to rise, while weaker numbers in the third quarter resulted in declining
rates. Inflation in the U.S. economy continues to be moderate. The Consumer
Price Index core rate (the CPI less food and energy prices), has risen 2.8% year
to date through September versus 3% for all of 1995. While 1996 has not been
favorable for the bond market, a continued slowing in the economy and favorable
inflation numbers should eventually result in lower long-term interest rates.

THE ARROW MUNICIPAL INCOME PORTFOLIO
    

     Interest rates increased beginning in the first quarter of 1996 on concerns
of fears of rising inflation due to higher commodity prices and stronger
economic growth. This continued until the latter part of the third quarter when
signs of economic strength began to ease. Thus far, inflation has remained
subdued.

   
     Municipal supply remains somewhat low in many areas. This has enabled
municipal prices to remain firm, and thus municipals have outperformed taxables
for most of the year. Going forward, the economic signals are mixed as to
whether the economy will strengthen or weaken further going into 1997.
    

   
     Therefore, the fund remains somewhat defensive with emphasis being placed
on intermediate average maturities and short to intermediate duration, along
with preference for premium coupon issues.

     Investor A Shares of the Arch Portfolio may be exchanged for Investor A
Shares of another portfolio offered by Arch or for Trust Shares or Institutional
Shares in the same Portfolio if the shareholder has a qualified trust, agency or
custodian account with the trust department of Mercantile Bank or any of its
affiliated or correspondent banks and the Trust Shares or Institutional Shares
are to be held in that account. Trust Shares of an Arch Portfolio may be
exchanged for Trust Shares of another portfolio offered by Arch or for Investor
A Shares of the same portfolio in connection with the distribution of assets
held in a qualified trust, agency or custodian account with the trust department
of Mercantile Bank or any of its affiliated or correspondent banks.

     Shareholders who exchange into any portfolio of Arch or Arrow that imposes
a sales charge may be subject to such sales charge if applicable and not
previously paid. Exchanges are only available in states where exchanges can
lawfully be made from one portfolio to another, and must satisfy the
requirements relating to the minimum initial investment in a portfolio. Arch and
Arrow reserve the right to reject any telephone exchange request and to modify
or terminate the exchange privilege (i) in the case of Arch, upon sixty days'
written notice to shareholders, or (ii) in the case of Arrow, with respect to
any shareholder who makes more than six exchanges in a year or more than three
exchanges in a calendar quarter, upon prior notification.

     Arch also offers an Automatic Exchange Program enabling Investor A
shareholders to automatically exchange Investor A Shares of one portfolio for
Investor A Shares of another portfolio.
