May 13, 2002

Dear Shareholder:

The Board of Directors of Principal High Yield Fund has called a special meeting
of shareholders for June 26, 2002 to vote on an Agreement and Plan of
Acquisition which provides for the combination of the Principal High Yield Fund
with the Principal Bond Fund. If the Plan is approved by shareholders and
implemented, you will cease to own shares of the High Yield Fund and will become
the owner of shares of the same class of the Bond Fund equal in value to your
shares of the High Yield Fund. The Board of the High Yield Fund believes that
the proposed change is in the best interest of the Fund and its shareholders.

Both Funds are income-oriented funds which invest primarily in corporate bonds
and seek a high level of current income. The principal difference between the
two Funds is that the High Yield Fund invests primarily in "junk bonds" and its
portfolio reflects the risks associated with such bonds, while the Bond Fund
invests primarily in "investment grade" bonds.

No matter how many shares you own, it is important that you take time to read
the prospectus/proxy statement and vote as soon as possible. If you have more
than one account in the High Yield Fund, you will receive multiple proxy
ballots. Please return ALL of the proxy ballots.
We appreciate your taking the time to respond on this important matter. If you
have questions regarding the proxy or the voting process, please call our proxy
solicitor, D.F. King & Co., Inc. at 1-800-_______. If you have questions
concerning your account, please call our shareholder services department
toll-free at 1-800-247-4123.

Sincerely,


/s/Ralph C. Eucher

Ralph C. Eucher
President
Principal High Yield Fund, Inc.


                                       4




     IMPORTANT INFORMATION TO HELP YOU UNDERSTAND AND VOTE ON THE PROPOSAL

Please read the complete prospectus/proxy statement. For your convenience, we
are providing this brief overview of the Agreement and Plan of Acquisition and
the transactions contemplated thereby (Plan) on which you are being asked to
vote.

WHAT WILL HAPPEN IF SHAREHOLDERS APPROVE THE PLAN AND IT BECOMES EFFECTIVE?

     At the effective time, which is scheduled for 3:00 p.m. C.D.T. on July
     31, 2002, Principal Bond Fund, Inc. (Bond Fund) will acquire all the
     assets and assume all the liabilities of Principal High Yield Fund,
     Inc. (High Yield Fund) and will issue to the High Yield Fund shares of
     its Class A and Class B common stock having a value equal to the net
     assets of the High Yield Fund that are being acquired. Immediately
     thereafter, the High Yield Fund will distribute Class A shares to its
     Class A shareholders and Class B shares to its Class B shareholders
     and thereby redeem all its outstanding shares. If you own Class A
     shares of the High Yield fund, you will receive Class A shares of the
     Bond Fund equal in value to the Class A shares of the High Yield Fund
     which you own at the effective time. If you own Class B shares of the
     High Yield fund, you will receive Class B shares of the Bond Fund
     equal in value to the Class B shares of the High Yield Fund which you
     own at the effective time. The acquisition will not dilute the value
     of your shares.

WHY HAS THE BOARD DECIDED TO RECOMMEND THE COMBINATION OF THE HIGH YIELD FUND
WITH THE BOND FUND?

     The High Yield Fund has not performed well relative to other "high
     yield" funds and has been unable to attain sufficient assets to
     achieve a competitive expense ratio. The Board does not believe these
     circumstances are likely to change and, after considering various
     alternatives, has concluded combining the High Yield Fund with the
     Bond Fund is in the best interests of the shareholders of both Funds.

HOW HAVE THE FUNDS PERFORMED IN RELATION TO EACH OTHER?

The total returns of the Funds for the 1-year, 5-year and 10-year periods ended
March 31, 2002 are as follows:


                                 TOTAL RETURN WITH MAXIMUM SALES CHARGE

 * Inception Date




WHAT ARE THE ADVANTAGES OF THE ACQUISITION?

     Because the Bond Fund is substantially larger than the High Yield
     Fund, the Board believes that shareholders will benefit from economies
     of scale.

                                       5




WHO WILL PAY THE FEES AND EXPENSES INCURRED BY THE FUNDS IN CONNECTION WITH THE
PLAN?

     Principal Management Corporation, the manager of the Funds, will bear
     all out-of-pocket fees and expenses incurred by the Funds in
     connection with the transactions contemplated by the Plan.

DO THE FUNDS HAVE SIMILAR INVESTMENT OBJECTIVES, POLICIES AND PROCEDURES?

     The investment objective of the Bond Fund is to provide as high a
     level of income as is consistent with preservation of capital and
     prudent investment risk while the investment objective of the High
     Yield Fund is to seek high current income. The High Yield Fund has a
     secondary objective of capital growth when consistent with the
     objective of high current income. Both funds invest in fixed-income
     securities and have the same fundamental and non-fundamental
     investment policies and restrictions but the Bond Fund invests
     primarily in investment grade securities, and as of October 31, 2001
     had only 7.52% of its portfolio invested in below investment grade
     securities ("junk bonds") while the High Yield Fund invests primarily
     in below investment grade securities. Thus, while the risks of
     investing in bond funds in general are similar for the Funds, the
     Funds have different risks due to the extent to which each invests in
     "junk bonds."

HOW DO THE EXPENSE STRUCTURES OF THE FUNDS COMPARE?

     The Funds have different contractual rates for management fees, but
     such fees for both Funds are reduced as assets reach higher levels.
     The current contractual rate for the High Yield Fund is 0.60% of the
     Fund's average daily net assets. The current contractual rate for the
     Bond Fund is 0.50% of the first $100 million of the Fund's average
     daily net assets, 0.45% of the next $100 million and 0.40% of the next
     $100 million. As a percentage of average daily net assets for the year
     ended October 31, 2001, each Fund had the following expenses:


                             HIGH YIELD FUND                BOND FUND
                             --------------                 ---------

     The Bond Fund's expenses, assuming implementation of the Plan on October
     31, 2001 as a percentage of average daily net assets are as follows:


                                                 BOND FUND
                                                 ---------

 Management Fees                       0.47%                    0.47%
 12b-1 Fees                            0.25%                    0.82%
 Other Expenses                        0.35%                    0.44%
 Total Operating Expenses              1.07%                    1.73%




WHAT WILL BE THE SIZE OF THE BOND FUND AFTER THE TRANSACTION?

     As of March 31, 2002, the High Yield Fund had net assets of $26.1
     million, and the Bond Fund had net assets of $186.9 million. The net
     assets of the High Yield Fund represent less than 14% of the net
     assets of the Bond Fund, and the manager of the Funds believes that
     their transfer will permit them to be managed more efficiently. The
     transfer of the assets will not have any adverse effect on the Bond
     Fund, and may increase the assets of the Bond Fund sufficiently to
     reach a reduced management fee level for the Fund.


                                       6



WHAT ARE THE FEDERAL TAX IMPLICATIONS?

     The transactions contemplated by the Plan will result in a tax-free
     "reorganization" under the Internal Revenue Code. The Funds have
     obtained an opinion from tax counsel to the effect that no gain or
     loss will be recognized by either Fund or its shareholders in
     connection with the transactions contemplated by the Plan and that
     your tax cost basis will not change, and that your holding period of
     the securities acquired in the transaction will include your holding
     period of the High Yield Fund shares.

WHAT DO I DO IF I WISH TO MAINTAIN AN INVESTMENT IN A "JUNK BOND" FUND?

     Princor Financial Services Corporation ("Princor"), the distributor of
     each of the Funds, offers shares of other high yield funds. Your
     registered representative, whether registered with Princor or another
     broker-dealer, can review alternative high yield mutual funds with
     you.

HAS THE BOARD OF DIRECTORS APPROVED THE PLAN?

     Yes. The Board of Directors of each of the Funds has approved the
     Plan. The Board of Directors of the High Yield Fund recommends that
     you vote in favor of the Plan.

WHAT IF THERE ARE NOT ENOUGH VOTES TO REACH A QUORUM BY THE SCHEDULED DATE OF
THE SHAREHOLDER MEETING?

     If a quorum is not obtained, the meeting will be postponed to allow
     time to solicit additional proxies from shareholders. We urge you to
     vote promptly after reviewing the enclosed material so that the
     meeting is not delayed.

HOW MANY VOTES AM I ENTITLED TO CAST?

     You are entitled to one vote for each share of the High Yield Fund
     owned on the record date, May 1, 2002. The number of shares that you
     owned on that date is stated on the enclosed proxy ballot.

HOW DO I VOTE MY SHARES?

     Voting is easy. You can vote your shares by completing and signing the
     enclosed proxy ballot and mailing it in the enclosed postage paid
     envelope or faxing a copy to 515-235-9235 (this is not a toll free
     number). You may also vote by telephone by calling toll free at
     1-800-944-8454 or by using the internet by accessing

     concerning the Plan or how to vote your shares, please call Principal
     Management Corporation at 1-800-944-8454.

                         proxy ballot.

Inc. (the "High Yield Fund") for use at a special meeting of the shareholders of
the High Yield Fund, to be held at 2:00 p.m. C.D.T., on June 26, 2002, at the
offices of Principal Management Corporation, 680 8th Street, Des Moines, Iowa
50392-0200, and at any adjournment of the meeting.

At the meeting, High Yield Fund shareholders ("you") will vote on an Agreement
and Plan of Acquisition ("Plan"). Under the Plan, if approved, Principal Bond
Fund, Inc. (the "Bond Fund") will acquire all the assets and assume all the
liabilities of the High Yield Fund and issue in exchange shares of its Class A
and Class B common stock. The High Yield Fund will immediately redeem all its
outstanding Class A and Class B shares by distributing the Bond Fund shares of
the same classes to you. As a result, you will have the same amount invested in
Class A shares and/or Class B shares of the Bond Fund that you have invested in
those share classes of the High Yield Fund at the effective time. The Funds'
manager, Principal Management Corporation, is also a party to the Plan and has
agreed to pay all expenses incurred by the Funds in connection with the Plan.

Both Funds are Maryland corporations organized by Principal Life Insurance
Company ("Principal Life") and registered as open-end, diversified management
investment companies under the Investment Company Act of 1940 (the "Investment
Company Act"). The Bond Fund's investment objective is to provide as high a
level of income as is consistent with preservation of capital and prudent
investment risk. The Bond Fund pursues this objective by investing primarily in
intermediate maturity, fixed income or debt securities rated BBB or higher by
Standard & Poor's Rating Service ("S&P") or Baa or higher by Moody's Investors
Services, Inc. ("Moody's"). The investment objective of the High Yield Fund is
to seek high current income with a secondary objective of capital growth when
consistent with the objective of high current income. The High Yield Fund
pursues its objective by investing in high yielding, lower and unrated
fixed-income securities, commonly referred to as "junk bonds". These securities
offer a higher yield than other, higher rated securities, but carry a greater
degree of risk and are considered speculative with respect to the issuers'
ability to pay interest and repay principal.

This prospectus/proxy statement sets forth concisely the information you should
know before voting on the proposed Plan. You should retain it for future
reference.

the High Yield Fund dated March 1, 2002 relating to this proxy statement/
prospectus have been filed with the Securities and Exchange Commission ("SEC")

                      INTRODUCTION AND VOTING INFORMATION

SPECIAL MEETING; VOTING OF PROXIES; ADJOURNMENT
- -----------------------------------------------
We are furnishing this prospectus/proxy statement to you as shareholders of the
High Yield Fund in connection with the solicitation by the Board of Directors of
the High Yield Fund of proxies to be used at a special meeting of the
shareholders of the High Yield Fund to be held on June 26, 2002 and at any
adjournment thereof. The purpose of the meeting is to vote on an Agreement and
Plan of Acquisition to which the High Yield Fund, the Bond Fund and the manager
of those Funds, Principal Management Corporation, are parties. The Plan provides
for the combination of the High Yield Fund with the Bond Fund, as more fully
described below. The prospectus/proxy statement is first being furnished to
shareholders on or about May 13, 2002.

THE BOARD OF DIRECTORS OF THE HIGH YIELD FUND HAS APPROVED THE PLAN AND
RECOMMENDS THAT THE SHAREHOLDERS OF THE HIGH YIELD FUND VOTE FOR THE PLAN AND
THE TRANSACTIONS WHICH IT CONTEMPLATES.

Shareholders of record of the High Yield Fund at the close of business on May 1,
2002, the record date, are entitled to vote at the meeting. As of the record
date, the High Yield Fund had _____ Class A shares and _____ Class B shares
outstanding and entitled to be voted. Shareholders are entitled to one vote for
each share of each Class held. A quorum must be present at the meeting for the
transaction of business. The holders of record of one-third of the shares
outstanding at the close of business on the record date present in person or
represented by proxy will constitute a quorum for the meeting. The approval of
the Plan requires the affirmative vote of a majority of all the votes entitled
to be cast by shareholders of the High Yield Fund. Abstentions and broker
non-votes (proxies from brokers or nominees indicating that they have not
received instructions from the beneficial owners on an item for which the broker
or nominee does not have discretionary power) are counted toward a quorum but do
not represent votes cast for the Plan or any other issue. If the shareholders of
the High Yield Fund do not approve the Plan, the Funds will consider possible
alternative arrangements, and Principal Management Corporation will continue to
manage the High Yield Fund.

To vote your shares:
 through the internet:    Access www.proxyvote.com
 by mail:                 return your proxy ballot in the enclosed
                            postage-paid envelope
 by fax:                  fax to 515-235-9235  (this is not a toll-free number)
 by telephone:            call toll-free 1-800-944-8454

The proxies will vote in accordance with your direction, as indicated on your
proxy ballot, if the proxy ballot is received and is properly executed. If you
properly execute your proxy ballot and give no voting instructions with respect
to the Plan, the proxies will vote your shares in favor of the Plan. The
proxies, in their discretion, may vote upon such other matters as may properly
come before the meeting. We are not aware of any other matters expected to come
before the meeting.

If either (i) a quorum is not present at the Meeting or (ii) a quorum is present
but sufficient votes in favor of approving the Plan are not received by 12:00
Noon C.D.T., June 26, 2002, then the persons named as proxies in the enclosed
form of proxy may propose one or more adjournments of the meeting to permit
further solicitation of proxies. Any such adjournment will require the
affirmative vote of at least a majority of the High Yield Fund Shares
represented, in person or by proxy, at the session of the meeting to be
adjourned. The proxies will vote those proxies that they are required to vote
FOR the Plan in favor of such an adjournment and will vote those proxies
required to be voted AGAINST the Plan against such an adjournment.

PROXY SOLICITATION
- ------------------
We will solicit proxies primarily by mail. Additional solicitations may be made
by internet, telephone, facsimile or personal contact by officers or employees
of the High Yield Fund or Principal Management Corporation who will not be
specially compensated for these services. In addition, the High Yield Fund has
retained D.F. King & Co., Inc. to solicit proxies for estimated fees and
expenses of $_____ for the services it provides to the High Yield Fund.
Principal Management Corporation will bear the costs of the meeting, including
costs of preparing and mailing the notice, the prospectus/proxy statement, and
the proxy ballot and of soliciting proxies. Banks, brokers, and other persons
holding High Yield Fund shares as nominees will be reimbursed for their
reasonable expenses incurred in sending proxy materials to and obtaining voting
information from the beneficial owners of those shares.


                                       11



The vote of the shareholders of the Bond Fund is not being solicited, because
their approval or consent is not necessary for the approval of the Plan.

REVOCATION OF PROXIES
- ---------------------
You may revoke your proxy: (i) at any time prior to the proxy's exercise by
sending written notice to the Secretary of the High Yield Fund, at 680 8th
Street, Des Moines, Iowa, 50392-0200 prior to the meeting; (ii) by the
subsequent execution and return of another proxy prior to the meeting; or (iii)
by being present and voting in person at the meeting after giving oral notice of
revocation to the Chairman of the meeting.

ADDITIONAL INFORMATION
- ----------------------
On May 1, 2002, the directors and officers of the High Yield Fund together owned
less than 1% of its outstanding shares and the directors and officers of the
Bond Fund together owned less than 1% of its outstanding shares. Principal Life,
Des Moines, Iowa, 50392-0200, an Iowa life insurance company and the parent of
the manager of the Funds, owned of record and beneficially, either directly or
through subsidiaries, _____% of the outstanding shares of the Bond Fund
(including _____% of the Class A shares and _____% of the Class B shares) and
_____% of the outstanding shares of the High Yield Fund (including _____% of the
Class A shares and _____% of the Class B shares) and, based on those holdings,
would own at the effective time _____% of the outstanding shares of the Bond
Fund (_____% of the Class A shares and _____% of the Class B shares). The
ultimate parent of Principal Life is Principal Financial Group, Inc. The Funds
do not know of any other person who owned at the record date, or will own at the
effective time, of record or beneficially 5% or more of the outstanding shares
of either Fund.

                                    SUMMARY

The following is a summary of certain information contained or incorporated by
reference in this prospectus/proxy statement. It is qualified in its entirety by
the more detailed information appearing elsewhere or incorporated by reference
in this prospectus/proxy statement.

THE PLAN
- --------
You are being asked to approve the Plan, which provides for the combination of
the High Yield Fund with the Bond Fund. Under the Plan, at the effective time on
the closing date, the Bond Fund will acquire all the assets and assume all the
liabilities of the High Yield Fund and issue to the High Yield Fund shares of
its Class A and Class B common stock having a value equal to the net assets
acquired attributable to each share class. Immediately thereafter, the High
Yield Fund will distribute all the Bond Fund shares to its Class A and Class B
shareholders and thereby redeem all its outstanding shares. Each High Yield Fund
shareholder will receive Bond Fund shares equal in value to the shares of the
same class of the High Yield Fund held by the shareholder at the effective time.
We expect the effective time will be 3:00 p.m. C.D.T. on July 31, 2002, although
the effective time is dependent upon the receipt of an exemptive order from the
SEC permitting the transaction.

REASONS FOR THE PLAN
- --------------------
We believe that the Plan will provide shareholders of the High Yield Fund with
an investment in a larger income-oriented bond fund with a more favorable
expense ratio and greater possibilities for economies of scale than are likely
with the High Yield Fund. The table below reflects the investment performance of
each of the Funds for the periods ended March 31, 2002.


                      TOTAL RETURN WITH MAXIMUM SALES CHARGE                  TOTAL RETURN AT NET ASSET VALUE
                      --------------                                          -----------
    FUND                      CLASS A                     CLASS B                  CLASS A                 CLASS B
    ----                      -------                     -------                  -------                 -------

 Bond             -1.50         5.16         8.79      -1.23    5.09      8.43       6.19       7.04      2.70   5.41
 High Yield      -10.06        -1.09         4.04      -9.81   -1.23     -5.55      -0.13       4.55     -6.39  -0.96

 



The High Yield Fund, whose inception was in December 1987, has a long history of
under-performance relative to other high yield funds. As of January 31, 2002,
the Fund's percentile rankings relative to all funds in Morningstar's High Yield
category were:


                                       12



                       . 10-year period = 85th percentile
                       . 5-year period = 73rd percentile
                       . 3-year period = 64th percentile
                       . 1-year period = 78th percentile

In part as a result of the High Yield Fund's longstanding under-performance, the
High Yield Fund has remained small. The High Yield Fund's small asset size is
insufficient to generate a competitive expense ratio. For example, the expense
ratio of the High Yield Fund's Class A shares was 1.42% versus an average of
1.04% for Morningstar's High Yield category (based on the oldest share class of
each fund, generally the Class A shares) as of January 31, 2002.

The High Yield Fund's Board has concluded that the High Yield Fund's performance
track record will remain a significant hindrance to sales and that the High
Yield Fund's expense ratio will remain uncompetitive, and that it would be
appropriate to stop offering shares of the High Yield Fund and to permit the
Bond Fund to acquire the assets of the High Yield Fund. The Board of the High
Yield Fund, including a majority of the directors who are not interested persons
of the High Yield Fund, has determined that the Plan is consistent with the best
interests of the High Yield Fund and its shareholders, that the terms of the
Plan are fair and reasonable and that the interests of the shareholders of the
High Yield Fund will not be diluted as a result of the transactions contemplated
by the Plan.

INVESTMENT OBJECTIVES AND POLICIES
- ----------------------------------
The investment objective of the Bond Fund is to provide as high a level of
income as is consistent with preservation of capital and prudent investment risk
while the investment objective of the High Yield Fund is to seek high current
income. The High Yield Fund has a secondary objective of capital growth when
consistent with the objective of high current income. Both Funds invest in
fixed-income securities, but the Bond fund invests primarily in investment grade
securities and as of October 31, 2001 had only 7.52% of its portfolio invested
in below investment grade securities ("junk bonds"), while the High Yield Fund
invests primarily in below investment grade securities. Thus, while the risks of
investing in bond funds in general are similar for the Funds, the Funds have
different risks due to the extent to which each invests in "junk bonds."

FEES AND EXPENSES OF THE FUNDS

This table describes the fees and expenses that you may pay if you buy and hold

ONE-TIME FEES
      . You may pay a one-time sales charge for each purchase (Class A shares)

        an initial sales charge. Investments of $1 million or more of Class A
        shares are sold without an initial sales charge but may be subject to a
        CDSC at the time of redemption.
      . Class B shares have no initial sales charge but may be subject to a
        CDSC. If you sell (redeem) shares and the CDSC is imposed, it will
        reduce the amount of sales proceeds.

                                       13



      . A redemption fee of 1.00% is charged on redemptions of Class A shares of
        $30,000 or more if the shares were purchased within 30 days of the
        redemption. The fee is calculated as a percentage of market value at the
        time the shares are redeemed.
      . An exchange fee of 1.00% is charged on exchanges of $30,000 or more
        among the Funds if the shares were purchased within 30 days of the
        exchange. The fee is calculated as a percentage of market value at the
        time the shares are exchanged.

The operating expenses attributable to the Class A and Class B shares of the
Funds (as a percentage of the average daily net assets) for the fiscal year
ended October 31, 2001 were as follows:

The Bond Fund's expenses, assuming implementation of the Plan on October 31,
2001, as a percentage of average daily net assets are as follows:


                                     BOND FUND

The following is an example of the effect of the operating expenses of the
Funds. The examples assume (1) a 5% annual return, and (2) the Funds' operating
expenses remain the same. Although your actual costs may be higher or lower, you
would pay the following expenses on a $10,000 investment in shares of the Funds,
based upon these assumptions:

PURCHASES
- ---------
Each Fund offers its shares for sale through Princor Financial Services
Corporation, a broker-dealer that is also the principal underwriter for the
Funds, or other dealers which it selects.

                                       14




ONGOING FEES
Each Fund pays ongoing fees to its Manager, Underwriter and others who provide
services to the Fund. They reduce the value of each share you own.

DISTRIBUTION (12B-1) FEES
Each of the Funds has adopted a Distribution Plan under Rule 12b-1 of the
Investment Company Act of 1940. Under the Distribution Plans, the Funds pay a
fee to Princor based on their average daily net asset values. These ongoing fees
pay expenses relating to distribution fees for sales of shares of the Funds and
for services provided by Princor and other selling dealers to shareholders.
Because they are ongoing fees, over time they may exceed other types of sales
charges.

                . Class A shares ..................0.25%
                . Class B shares ..................1.00%

EXCHANGES
- ---------
Shares of both Funds may be exchanged, without a sales charge or CDSC, for
shares of the same class of other funds sponsored by Principal Life Insurance
Company. If Class B shares of the Funds are exchanged for Class B shares of
other funds, the shares acquired will be subject to the applicable CDSC imposed
by the new fund; however, the holding period of the Class B shares exchanged is
added to the holding period of the Class B shares acquired for purposes of
determining the applicable charge.

REDEMPTION PROCEDURES AND FEES
- ------------------------------
Shares of the Funds may be redeemed at a price equal to the net asset value of
the shares next computed following the receipt of a request for redemption in
proper form.

The amount you receive will be reduced by any applicable CDSC or redemption fee.
Generally, the sale proceeds are sent out on the next business day after the
sell order has been placed.

DIVIDENDS AND DISTRIBUTIONS
- ---------------------------
The Bond Fund and High Yield Fund pay their net investment income on a monthly
basis. Payments are made to shareholders of record on the business day prior to
the payment date. The payment date is the 19th of each month (or previous
business day).

Net realized capital gains, if any, are distributed annually. Generally the
distribution is made on the second business day of December. Payments are made
to shareholders of record on the business day prior to the payable date. Capital
gains may be taxable at different rates, depending on the length of time that
the Fund holds its assets.

Immediately prior to the reorganization, each of the Funds will pay a dividend
or dividends which, together with all previous dividends, will have the effect
of distributing to their respective shareholders all of their investment company
taxable income for taxable years ending on or prior to the reorganization
(computed without regard to any deduction for dividends paid) and all of its net
capital gains, if any, realized in taxable years ending on or prior to the
reorganization (after reduction for any available capital loss carry forward).
Such dividends will be included in the taxable income of each Fund's respective
shareholders.

FEDERAL INCOME TAX CONSEQUENCES OF THE PROPOSED COMBINATION
- -----------------------------------------------------------
The combination will be a tax-free "reorganization" under the Internal Revenue
Code of 1986, as amended (the "Code"). In the opinion of tax counsel to the
Funds, no gain or loss will be recognized by either Fund or its shareholders, in
connection with the combination, and the tax cost basis of the Bond Fund shares
received by High Yield Fund shareholders will equal the tax cost basis of their
shares in the High Yield Fund and their holding period of the Bond Fund shares
will include the time during which the shareholders held the High Yield Fund
shares.

COSTS AND EXPENSES
- ------------------
Principal Management Corporation will bear all out-of-pocket fees and expenses
incurred by the Funds in connection with the transactions contemplated by the
Plan.

                                       15




CONTINUATION OF SHAREHOLDER ACCOUNTS
- ------------------------------------
At the effective time, you will cease to be a shareholder of the High Yield Fund
and will become a shareholder of the Bond Fund owning Class A shares and/or
Class B shares of the Bond Fund having the same value as the investment you had
in the High Yield Fund at the effective time.

                             PRINCIPAL RISK FACTORS

The investment objective of the Bond Fund is to provide as high a level of
income as is consistent with preservation of capital and prudent investment risk
while the investment objective of the High Yield Fund is to seek high current
income. The High Yield Fund has a secondary objective of capital growth when
consistent with the objective of high current income. Both Funds invest in
fixed-income securities, but the Bond fund invests primarily in investment grade
securities and as of October 31, 2001 had only 7.52% of its portfolio invested
in below investment grade securities, while the High Yield Fund invests
primarily in below investment grade securities. Thus, while the risks of
investing in bond funds in general are similar for the Funds, the Funds have
different risks due to the extent to which each invests in "junk bonds." As with
all mutual funds, as the values of the assets of Bond Fund and High Yield Fund
rise or fall, the Funds' share prices change. If you sell your shares when their
value is less than the price you paid, you will lose money.

MAIN RISKS FOR BOND FUND
The average portfolio duration of the Bond Fund normally varies within a three-
to six-year time frame based on the Manager's forecast for interest rates.
Duration is a measure of the expected life of a fixed-income security that is
used to determine the sensitivity of a security's price to changes in interest
rates. For example, if the portfolio duration of the Fund is three years, a
change of 1% in the Fund's yield results in a change of approximately 3% in the
value of the Fund's securities. The longer a security's duration, the more
sensitive it is to changes in interest rates. A Fund with a longer average
portfolio duration will be more sensitive to changes in interest rates than a
Fund with a shorter average portfolio duration.

Mortgage-backed securities are subject to prepayment risk. When interest rates
decline, significant unscheduled prepayments may result. These prepayments must
then be reinvested at lower rates. Prepayments may also shorten the effective
maturities of these securities, especially during periods of declining interest
rates. On the other hand, during periods of rising interest rates, a reduction
in prepayments may increase the effective maturities of these securities,
subjecting them to the risk of decline in market value in response to rising
interest rates. This may increase the volatility of the Bond Fund.

When interest rates fall, the price of a debt security rises and when interest
rates rise, the price declines. In addition, the value of securities held by the
Bond Fund may be affected by factors such as credit rating of the entity that
issued the security and its maturity. Lower quality and longer maturity
securities will be subject to greater credit risk and price fluctuations than
higher quality and shorter maturity securities.

Fixed-income securities that are not investment grade are commonly referred to
as junk bonds or high yield securities. These securities offer a potentially
higher yield than other, higher rated securities, but they carry a greater
degree of risk and are considered speculative by the major credit rating
agencies.

MAIN RISKS FOR HIGH YIELD FUND
Investors assume special risks when investing in the High Yield Fund. Compared
to higher rated securities, lower rated securities may:
      . have a more volatile market value, generally reflecting specific events
        affecting the issuer;
      . be subject to greater risk of loss of income and principal (issuers are
        generally not as financially secure);
      . have a lower volume of trading, making it more difficult to value or
        sell the security; and
      . be more susceptible to a change in value or liquidity based on adverse
        publicity and investor perception, whether or not based on factual
        analysis.

The market for higher-yielding, lower-rated securities has not been tested by an
economic recession. An economic downturn may severely disrupt the market for
these securities. This could cause financial stress to the issuer negatively

                                       16



affecting the issuer's ability to pay principal and interest. This may also
negatively affect the value of the High Yield Fund's securities. In addition, if
an issuer defaults, the Fund may have additional expenses if it tries to recover
the amounts due it.

Some securities the High Yield Fund buys have call provisions. A call provision
allows the issuer of the security to redeem it before its maturity date. If a
bond is called in a declining interest rate market, the Fund would have to
replace it with a lower yielding security. This results in a decreased return
for investors. In addition, in a rising interest rate market, a higher yielding
security's value decreases. This is reflected in a lower share price for the
Fund.

The High Yield Fund tries to minimize the risks of investing in lower rated
securities by diversification, investment analysis and attention to current
developments in interest rates and economics conditions. Although the Fund's
Manager considers securities ratings when making investment decisions, it
performs its own investment analysis. This analysis includes traditional
security analysis considerations such as:
      . experience and managerial strength
      . changing financial condition
      . borrowing requirements or debt maturity schedules
      . responsiveness to changes in business conditions
      . relative value based on anticipated cash flow
      . earnings prospects

The Manager continuously monitors the issuers of the Fund's securities to
determine if the issuers will have sufficient cash flow and profits to meet
required principal and interest payments. It also monitors each security to
assure the security's liquidity so the Fund can meet requests for sales of Fund
shares.

For defensive purposes, the Fund may invest in other securities. During periods
of adverse market conditions, the Fund may invest in all types of money market
instruments, higher rated fixed-income securities or any other fixed-income
securities consistent with the temporary defensive strategy. The yield to
maturity on these securities is generally lower than the yield to maturity on
lower rated fixed-income securities.

                                    THE PLAN

AGREEMENT AND PLAN OF ACQUISITION
- ---------------------------------
The terms of the Plan are summarized below. The summary is qualified in its
entirety by reference to the Plan, a copy of which is attached as Appendix A.

Under the Plan, the Bond Fund will acquire all the assets and assume all the
liabilities of the High Yield Fund and will issue to the High Yield Fund the
number of shares of Class A and Class B Common Stock of the Bond Fund that have
a net asset value equal to the net asset value attributable to Class A and Class
B shares of the High Yield Fund.   We expect that the closing date will be July
31, 2002, assuming shareholder approval of the Plan and the obtaining of an SEC
order permitting the transaction, and that the effective time will be the close
of regular trading on the NYSE at 4:00 P.M., Eastern Time, on that date. The
Funds will determine their net asset values as of the effective time using the
procedures described in the Bond Fund's prospectus. The Bond Fund will issue to
the High Yield Fund a number of Class A and Class B shares equal to the value of
the assets of the High Yield Fund Class A and Class B shares outstanding at the
effective time. The High Yield Fund will be managed such that at the effective
time it will hold only cash or other securities that are eligible investments
for the Bond Fund.

Immediately after the effective time, the High Yield Fund will distribute to you
its Bond Fund shares of the same class as the shares you own of the High Yield
Fund in exchange for all your High Yield Fund shares of that class. Each High
Yield Fund shareholder will receive shares of the Bond Fund that are equal in
value to the shares of the class of the High Yield Fund that are given up by the
shareholder in the exchange. In connection with the exchange, the Bond Fund will
credit on its books an appropriate number of its shares to the account of each
High Yield Fund shareholder, and the High Yield Fund will cancel on its books
all its shares registered to the account of that shareholder.   Any outstanding
certificate for High Yield Fund shares that is not surrendered will be deemed to
represent the number of Bond Fund shares for which the High Yield shares have
been exchanged. After the effective time, the High Yield Fund will dissolve in
accordance with applicable law.

                                       17




The consummation of the transactions contemplated by the Plan is subject to the
approval of the Plan by the shareholders of the High Yield Fund, the continued
correctness at the closing of the representations and warranties of the High
Yield Fund in the Plan, the delivery by the High Yield Fund to the Bond Fund of
a list of assets and liabilities being transferred and the High Yield Fund's
receipt of an SEC order permitting the transaction. The Plan may be amended in
any manner mutually-agreeable to the Funds, except that no amendment may be made
to the Plan which in the opinion of the Board of Directors of the High Yield
Fund would materially adversely affect the interests of the shareholders of that
Fund. Either Fund may terminate the Plan at any time before the effective time
if it believes that consummation of the transactions contemplated by the Plan
would not be in the best interests of its shareholders.

Principal Management Corporation, the manager of the Funds, will pay all fees
and out-of-pocket expenses incurred by the Funds in connection with the
transactions contemplated by the Plan.

DESCRIPTION OF SECURITIES TO BE ISSUED
- --------------------------------------
The Class A and Class B Shares of the Bond Fund are shares of common stock, par
value $.01 per share. They have the same rights with respect to the Bond Fund as
the Class A and Class B Shares of the High Yield Fund have with respect to the
High Yield Fund. Each share is entitled to one vote and has equal rights with
every other share as to dividends, earnings, voting, assets and redemption.
There is no cumulative voting for directors. Shares are fully paid and
non-assessable, have no preemptive or conversion rights and are freely
transferable. Each fractional share has proportionately the same rights as are
provided for a full share. As of ______________, 2002, the Bond Fund had
________ Class A shares and ________ Class B shares outstanding.

REASONS FOR THE PROPOSED COMBINATION
- ------------------------------------
The High Yield Fund, whose inception was in December 1987, has a long history of
under-performance relative to other high yield funds. As of January 31, 2002,
the Fund's percentile rankings relative to all funds in Morningstar's High Yield
category were:

                       . 10-year period = 85th percentile
                       . 5-year period = 73rd percentile
                       . 3-year period = 64th percentile
                       . 1-year period = 78th percentile

In part as a result of the Fund's longstanding under-performance, the Fund has
remained small. The Fund's small asset size is insufficient to generate a
competitive expense ratio. For example, the expense ratio of the Fund's Class A
shares was 1.42% versus an average of 1.04% for Morningstar's High Yield
category (based on the oldest share class of each fund, generally the Class A
shares) as of January 31, 2002.

The High Yield Fund's Board has concluded that the High Yield Fund's performance
track record will remain a significant hindrance to sales and that the Fund's
expense ratio will remain uncompetitive, and that it would be appropriate to
stop offering shares of the High Yield Fund and to permit the Bond Fund to
acquire the assets of the High Yield Fund. The Board of the High Yield Fund,
including a majority of the directors who are not interested persons of the
Fund, has determined that the Plan is consistent with the best interests of the
High Yield Fund and its shareholders, that the terms of the Plan are fair and
reasonable and that the interests of the shareholders of the Fund will not be
diluted as a result of the transactions contemplated by the Plan.

The Plan has been approved by the Board of Directors of each of the Funds,
including a majority of the directors of each Fund who are not "interested
persons" of that Fund as defined in Section 2(a)(19) of the Investment Company
Act. In approving the Plan, the Boards considered the investment objectives of
the two Funds and determined that interests of the existing shareholders in
their respective Funds will not be diluted as a result of the transactions
contemplated by the Plan. The High Yield Fund Board considered the following
factors, among others: (1) possible alternatives to the Plan; (2) the terms and
conditions of the Plan and whether its implementation would result in dilution
of shareholder interests or involve overreaching by any person concerned; (3)
the advantages to the High Yield Fund's shareholders of investing in a larger
asset pool with greater diversification; (4) the possible benefits of a larger
asset base to portfolio management of the Bond Fund; (5) any direct or indirect
fees or expenses incurred by the Funds as a result of the Plan; (6) expense
ratios and available information regarding the fees and expenses of the Funds,
including

                                       18



any change in fees or expenses to be paid or borne by shareholders of the High
Yield Fund (direct or indirectly) as a result of the Plan; (7) comparative
investment performances of the Funds; (8) the direct or indirect federal income
tax consequences of the Plan to shareholders of the High Yield Fund; (9) the
continuity of or changes in services to be provided to shareholders following
implementation of the Plan; and (10) the compatibility of the investment
objectives and policies of the Funds and changes with respect to the investment
objectives and policies of the High Yield Fund that will result from the Plan.

FEDERAL INCOME TAX CONSEQUENCES
- -------------------------------
To be considered a tax-free "reorganization" under the applicable provisions of
the Code, a reorganization must exhibit a continuity of business enterprise.
Because the Bond Fund will use a portion of the High Yield Fund's assets in its
business and will continue the High Yield Fund's historic business, the
combination of the High Yield Fund with the Bond Fund will exhibit a continuity
of business enterprise. Therefore, the combination will be considered a tax-free
"reorganization," under applicable provisions of the Code. In the opinion of tax
counsel to the Funds, no gain or loss will be recognized by either Fund or its
shareholders in connection with the combination, the tax cost basis of the Bond
Fund shares received by High Yield Fund shareholders will equal the tax cost
basis of their shares in the High Yield Fund, and their holding periods for the
Bond Fund shares will include their holding periods for the High Yield Fund
shares.

As of October 31, 2001, High Yield Fund had accumulated capital loss
carryforwards in the amount of approximately $12,704,699. After the
reorganization, these losses will be available to the Bond Fund to offset its
capital gains, although the amount of these losses which may offset the Bond
Fund's capital gains in any given year may be limited. As a result of this
limitation, it is possible that the Bond Fund may not be able to use these
losses as rapidly as the High Yield Fund might have, and part of these losses
may not be useable at all. The ability of the Bond Fund to absorb losses in the
future depends upon a variety of factors that cannot be known in advance,
including the existence of capital gains against which these losses may be
offset. In addition, the benefits of any capital loss carryfowards currently are
available only to shareholders of High Yield Fund. After the reorganization,
however, these benefits will inure to the benefit of all shareholders of the
Bond Fund.

The foregoing is only a summary of the principal federal income tax consequences
of the combination and should not be considered to be tax advice. There can be
no assurance that the Internal Revenue Service will concur on all or any of the
issues discussed above. You may wish to consult with your own tax advisers
regarding the federal, state, and local tax consequences with respect to the
foregoing matters and any other considerations which may apply in your
particular circumstances.

                  MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

On January 3, 2001, the Federal Open Market Committee (FOMC), which sets the
rate that banks charge for overnight reserve loans, reduced the federal funds
rate by 0.50%, and began an unprecedented cycle of easing monetary policy in an
attempt to revive the deteriorating U.S. economy. While corporate earnings were
sluggish during the first quarter of 2001, the U.S. consumer continued to spend
at a brisk pace and to lend considerable support to the economy. However, just
as corporate profits were poised for a recovery in early 2002, consumer
confidence began to wane. This trend was exacerbated by the September 11
terrorist attacks that virtually assured an economic recession in the United
States and postponed the prospects for recovery further into 2002. The FOMC
reduced the federal funds rate seven times during 2001 prior to the attacks, and
then reduced rates two more times between September 11 and October 31.

                                       19



The federal funds rate was 2.5% as of October 31, 2001. Corporate bond investors
began the year looking past poor corporate earnings and focused on historically
high-risk premiums and prospects for a late 2001 economic turnaround. Risk
premiums of U.S. Treasuries remain high not only because of poor corporate
performance and related price volatility, but because of the new risks
introduced to the market after the attacks. Though market reactions remain
severe for those companies that disappoint investors, corporate bonds
outperformed all asset classes throughout the year until the attacks. This event
drove investors to seek "safe haven" assets such as U.S. Treasuries and
agencies. As a result, U.S. Treasury rates have fallen (prices have risen)
across all maturities. For the one-year period ended October 31, 2001, the Fund
returned 9.51% compared to 14.56% for the Lehman Aggregate Index. Throughout the
year, we reduced the Fund's exposure to adverse corporate bond price movements
and emphasized investments in those industries with the most visible earnings
prospects. While the Fund is still overweight corporate bonds relative to the
Index, this position has been significantly reduced throughout the year. For the
year, the Fund's overweight to investment grade corporate bonds relative to the
Index greatly enhanced returns, although some of this performance was given up
after the attacks. The Fund benefited from being overweight to asset-backed
securities (ABS) and commercial mortgage-backed securities (CMBS), and being
slightly underweight to agency mortgage-backed securities (MBS) relative to the
Index. Being underweight in U.S. Treasuries and agencies relative to the Index
hindered performance since the attacks. Performance was further diminished by
holdings in below investment grade corporate bonds, although these positions
were reduced throughout the year. We expect the current historically high-risk
premiums to decline in 2002, which will cause outperformance in corporate bonds,
CMBS, and ABS versus Treasuries. The portfolio is well positioned for this
event.

                                       20

Directors without shareholder approval.

BOND FUND
- ---------
The Bond Fund seeks to provide as high a level of income as is consistent with
preservation of capital and prudent investment risk.

BOND STRATEGY
The Fund invests primarily in intermediate maturity fixed-income or debt
securities rated BBB or higher by Standard & Poor's Rating Service ("S&P") or
Baa or higher by Moody's Investors Service, Inc. ("Moody's"). The Fund considers
the term "bond" to mean any debt security. Under normal market and economic
circumstances, the Bond Fund invests at least 80% of its assets in:
      . securities issued or guaranteed by the U.S. Government or its agencies
        or instrumentalities;
      . mortgage-backed securities representing an interest in a pool of
        mortgage loans;
      . debt securities and taxable municipal bonds rated, at the time of
        purchase, in one of the top four categories by S&P or Moody's or, if not
        rated, in the opinion of the Manager of comparable quality; and
      . securities issued or guaranteed by the governments of Canada (Provincial
        or Federal Government) or the United Kingdom payable in U.S. dollars.

The rest of the Bond Fund's assets may be invested in:
      . preferred and common stock that may be convertible (may be exchanged for
        a fixed number of shares of common stock of the same issuer) or may be
        non-convertible; or
      . securities rated less than the four highest grades of S&P or Moody's but
        not lower than BB- (S&P) or Ba3 (Moody's) (i.e. less than investment
        grade).

Under unusual market or economic conditions, the Bond Fund may invest up to 100%
of its assets in cash and cash equivalents.

During the fiscal year ended October 31, 2001, the average ratings of the Bond
Fund's assets, based on market value at each month-end, were as follows (all
ratings are by Moody's):


                                                             
   48.45% in securities rated Aaa  24.59% in securities rated Baa  2.15% in securities rated B
   4.68% in securities rated Aa    5.06% in securities rated Ba    0.31% in securities rated Caa
   14.76% in securities rated A




HIGH YIELD FUND
- ---------------
The High Yield Fund seeks high current income primarily by purchasing high
yielding, lower or non-rated fixed-income securities which are believed not to
involve undue risk to income or principal. Capital growth is a secondary
objective when consistent with the objective of high current income.

HIGH YIELD STRATEGY
Under normal market conditions, the High Yield Fund invests at least 80% of its
assets in high yield, lower or unrated fixed-income securities. Fixed-income
securities that are commonly known as "junk bonds" or high yield securities.
These securities offer a higher yield than other, higher rated securities, but
they carry a greater degree of risk and are considered to be speculative with
respect to the issuer's ability to pay interest and repay principal.

The High Yield Fund invests its assets in securities rated Ba1 or lower by
Moody's or BB+ or lower by S&P. The Fund may also invest in unrated securities
which the Manager believes to be of comparable quality. The High Yield Fund does
not invest in securities rated below Caa (Moody's) or below CCC (S&P) at the
time of purchase. The SAI contains descriptions of the securities rating
categories.

During the fiscal year ended October 31, 2001, the average ratings of the High
Yield Fund's assets, based on market value at each month-end, were as follows
(all ratings are by Moody's):

                                       21





                                                             
   0.24% in securities rated AAA   33.56% in securities rated Ba   0.14% in securities rated Ca
   0.37% in securities rated A     57.97% in securities rated B    0.12% in securities rated C
   5.27% in securities rated Baa   2.27% in securities rated Caa   0.06% in securities rated D




The above percentages for Baa, Ba, B, and Caa rated securities include 0.11%,
3.28%, 3.16% and 0.13% respectively of unrated securities which have been
determined by the Manager to be of comparable quality.

While the Funds have different investment objectives and strategies, they have
the same investment policies and restrictions.

Neither Fund may:
      . Invest in commodities or commodity contracts, but it may purchase and
        sell financial futures contracts and options on such contracts;
      . Invest in real estate, although it may invest in securities which are
        secured by real estate and securities of issuers which invest or deal in
        real estate;
      . Borrow money, except for temporary or emergency purposes, in an amount
        not to exceed 5% of the value of the Fund's total assets at the time of
        the borrowing;
      . Make loans, except that the Fund may a) purchase and hold debt
        obligations in accordance with its investment objective and policies, b)
        enter into repurchase agreements, and c) lend its portfolio securities
        without limitation against collateral (consisting of cash or securities
        issued or guaranteed by the U.S. Government or its agencies or
        instrumentalities) equal at all times to not less than 100% of the value
        of the securities loaned.
      . Invest more than 5% of its total assets in the securities of any one
        issuer (other than obligations issued or guaranteed by the U.S.
        Government or its agencies or instrumentalities) or purchase more than
        10% of the outstanding voting securities of any one issuer, except that
        these limitations shall apply only with respect to 75% of the Fund's
        total assets.
      . Act as an underwriter of securities, except to the extent the Fund may
        be deemed to be an underwriter in connection with the sale of securities
        held in its portfolio.
      . Concentrate its investments in any particular industry or industries,
        except that the Fund may invest not more than 25% of the value of its
        total assets in a single industry.
      . Sell securities short (except where the Fund holds or has the right to
        obtain at no added cost a long position in the securities sold that
        equals or exceeds the securities sold short) or purchase any securities
        on margin, except it may obtain such short-term credits as are necessary
        for the clearance of transactions. The deposit or payment of margin in
        connection with transactions in options and financial futures contracts
        is not considered the purchase of securities on margin.
      . Invest in interests in oil, gas or other mineral exploration or
        development programs, although the Fund may invest in securities of
        issuers which invest in or sponsor such programs.

Each of the Funds has also adopted the same non-fundamental policies, which may
be changed without shareholder approval, dealing with investments in illiquid
securities, warrants, securities of any issuer having less than three years'
continuous operation, securities of other investment companies, pledging,
mortgaging or hypothecating its assets, investing in companies for the purpose
of exercising control or management, securities of foreign issuers, writing or
purchasing of put and call options, initial margin and premiums on financial
futures contracts and options on such contracts, arbitrage transactions and
investing in real estate limited partnership interests.

Each Fund has also adopted a non-fundamental restriction which requires it,
under normal circumstances, to invest at least 80% of its net assets in the type
of securities (as described in the prospectus) as suggested by the name of the
Fund. The Fund will provide 60-days notice to shareholders prior to implementing
a change in this policy for the Fund.

          any other material contractual or statutory restriction of any kind or
          character to which it is subject;

       (g) This Agreement has been duly authorized, executed, and delivered by
          the High Yield Fund and constitutes a valid and binding agreement of
          the High Yield Fund, and all governmental and other approvals required
          for the High Yield Fund to carry out the transactions contemplated
          hereunder have been or on or prior to the Closing Date will have been
          obtained;

       (h) On the Closing Date the High Yield Fund will own its assets free and
          clear of all liens, claims, charges, options, and encumbrances and,
          except for the Management Agreement, Investment Service Agreement,
          Distribution Agreement, Distribution and Shareholder Servicing
          Agreement and the Custodian Agreement with Bank of New York, there
          will be no material contracts or agreements (other than this
          Agreement) outstanding to which the High Yield Fund is a party or to
          which it is subject;

       (i) On the Closing Date the High Yield Fund will have full right, power
          and authority to sell, assign and deliver the assets to be sold,
          assigned, transferred and delivered to the Bond Fund hereunder, and
          upon delivery and payment for such assets, the Bond Fund will acquire
          good, marketable title thereto free and clear of all liens, claims,
          charges, options and encumbrances;

       (j) The High Yield Fund will declare to shareholders of record on or
          prior to the Closing Date a dividend or dividends which, together with
          all previous such dividends, shall have the effect of distributing to
          the shareholders all of its income (computed without regard to any
          deduction for dividends paid) and all of its net realized capital
          gains, if any, as of the Closing; and

       (k) The High Yield Fund will, from time to time, as and when requested by
          the Bond Fund, execute and deliver or cause to be executed and
          delivered all such assignments and other instruments, and will take
          and cause to be taken such further action, as the Bond Fund may deem
          necessary or desirable in order to vest in and confirm to the Bond
          Fund title to and possession of all the assets of the High Yield Fund
          to be sold, assigned, transferred and delivered hereunder and
          otherwise to carrot the intent and purpose of this Agreement.

     3.Based on the respective representations and warranties, subject to the
       terms and conditions contained herein, the High Yield Fund agrees to
       transfer to the Bond Fund and the Bond Fund agrees to acquire from the
       High Yield Fund, all of the assets of the High Yield Fund on the Closing
       Date and to assume from the High Yield Fund all of the liabilities of the
       High Yield Fund in exchange for the issuance of the number of shares of
       the Bond Fund provided in Section 4 which will be subsequently
       distributed pro rata to the shareholders of the High Yield Fund in
       complete liquidation and termination of the High Yield Fund and in
       exchange for all of the High Yield Fund's outstanding shares. The High
       Yield Fund shall not issue, sell or transfer any of its shares after the
       Closing Date, and only redemption requests received by the High Yield
       Fund in proper form prior to the Closing Date shall be fulfilled by the
       High Yield Fund. Redemption

                                       27



       requests received by the High Yield Fund thereafter shall be treated as
       requests for redemption of those shares of the Bond Fund allocable to the
       shareholder in question as provided in Section 6 of this Agreement.

     4.On the Closing Date, the Bond Fund will issue to the High Yield Fund a
       number of full and fractional shares of the Bond Fund, taken at their
       then net asset value, having an aggregate net asset value equal to the
       aggregate value of the net assets of the High Yield Fund. The aggregate
       value of the net assets of the High Yield Fund and the Bond Fund shall be
       determined in accordance with the then current Prospectus of the Bond
       Fund as of closing of the New York Stock Exchange on the Closing Date.

     5.The closing of the transactions contemplated in this Agreement (the
       "Closing") shall be held at the offices of Principal Management, 680 8th
       Street, Des Moines, Iowa 50392-0200 (or at such other place as the
       parties hereto may agree) at 3:00 p.m. Central Daylight Time on July 31,
       2002 or on such earlier or later date as the parties hereto may mutually
       agree. The date on which the Closing is to be held as provided in this
       Agreement shall be known as the "Closing Date."

     In the event that on the Closing Date (a) the New York Stock Exchange is
       closed for other than customary week-end and holiday closings or (b)
       trading on said Exchange is restricted or (c) an emergency exists as a
       result of which it is not reasonably practicable for the Bond Fund or the
       High Yield Fund to fairly determine the value of its assets, the Closing
       Date shall be postponed until the first business day after the day on
       which trading shall have been fully resumed.

     6.As soon as practicable after the Closing, the High Yield Fund shall (a)
       distribute on a pro rata basis to the shareholders of record of the High
       Yield Fund at the close of business on the Closing Date the shares of the
       Bond Fund received by the High Yield Fund at the Closing in exchange for
       all of the High Yield Fund's outstanding shares, and (b) be liquidated
       and dissolved in accordance with applicable law and its Articles of
       Incorporation.

     For purposes of the distribution of shares of the Bond Fund to
       shareholders of the High Yield Fund, the Bond Fund shall credit on the
       books of the Bond Fund an appropriate number of shares of the Bond Fund
       to the account of each shareholder of the High Yield Fund. The Bond Fund
       will issue a certificate or certificates only upon request and, in the
       case of a shareholder of the High Yield Fund whose shares are represented
       by certificates, only upon surrender of such certificates. No
       certificates will be issued for fractional shares of the Bond Fund. After
       the Closing Date and until surrendered, each outstanding certificate
       which, prior to the Closing Date, represented shares of the High Yield
       Fund, shall be deemed for all purposes of the Bond Fund's Articles of
       Incorporation and Bylaws to evidence the appropriate number of shares of
       the Bond Fund to be credited on the books of the Bond Fund in respect of
       such shares of the High Yield Fund as provided above.

     7.Subsequent to the execution of this Agreement and prior to the Closing
       Date, the High Yield Fund shall deliver to the Bond Fund a list setting
       forth the assets to be assigned, delivered and transferred to the Bond
       Fund, including the securities then owned by the High Yield Fund and the
       respective federal income tax bases (on an identified cost basis)
       thereof, and the liabilities to be assumed by the Bond Fund pursuant to
       this Agreement.

     8.All of the High Yield Fund's portfolio securities shall be delivered by
       the High Yield Fund's custodian on the Closing Date to the Bond Fund or
       its custodian, either endorsed in proper form for transfer in such
       condition as to constitute good delivery thereof in accordance with the
       practice of brokers or, if such securities are held in a securities
       depository within the meaning of Rule 17f-4 under the 1940 Act,
       transferred to an account in the name of the Bond Fund or its custodian
       with said depository. All cash to be delivered pursuant to this Agreement
       shall be transferred from the High Yield Fund's account at its custodian
       to the Bond Fund's account at its custodian. If on the Closing Date the
       High Yield Fund is unable to make good delivery pursuant to this Section
       8 to the Bond Fund's custodian of any of the High Yield Fund's portfolio
       securities because such securities have not yet been delivered to the
       High Yield Fund's custodian by its brokers or by the transfer agent for
       such securities, then the delivery requirement of this

                                       28



       Section 8 with respect to such securities shall be waived, and the High
       Yield Fund shall deliver to the Bond Fund's custodian on or by said
       Closing Date with respect to said undelivered securities executed copies
       of an agreement of assignment in a form satisfactory to the Bond Fund,
       and a due bill or due bills in form and substance satisfactory to the
       custodian, together with such other documents including brokers'
       confirmations, as may be reasonably required by the Bond Fund.

     9.
       The obligations of the Bond Fund under this Agreement shall be subject to
       receipt by the Bond Fund on or prior to the Closing Date of:

       (a) Copies of the resolutions adopted by the Board of Directors of the
          High Yield Fund and its shareholders authorizing the execution of this
          Agreement by the High Yield Fund and the transactions contemplated
          hereunder, certified by the Secretary or Assistant Secretary of the
          High Yield Fund;

       (b) A certificate of the Secretary or Assistant Secretary of the High
          Yield Fund as to the signatures and incumbency of its officers who
          executed this Agreement on behalf of the High Yield Fund and any other
          documents delivered in connection with the transactions contemplated
          thereby on behalf of the High Yield Fund;

       (c) A certificate of an appropriate officer of the High Yield Fund as to
          the fulfillment of all agreements and conditions on its part to be
          fulfilled hereunder at or prior to the Closing Date and to the effect
          that the representations and warranties of the High Yield Fund are
          true and correct in all material respects at and as of the Closing
          Date as if made at and as of such date; and

       (d) Such other documents, including an opinion of counsel, as the Bond
          Fund may reasonably request to show fulfillment of the purposes and
          conditions of this Agreement.

     10.  The obligations of the High Yield Fund under this Agreement shall be
       subject to receipt by the High Yield Fund on or prior to the Closing Date
       of:

       (a) Copies of the resolutions adopted by the Board of Directors of the
          Bond Fund authorizing the execution of this Agreement and the
          transactions contemplated hereunder, certified by the Secretary or
          Assistant Secretary of the Bond Fund;

       (b) A certificate of the Secretary or Assistant Secretary of the Bond
          Fund as to the signatures and incumbency of its officers who executed
          this Agreement on behalf of the Bond Fund and any other documents
          delivered in connection with the transactions contemplated thereby on
          behalf of the Bond Fund;

       (c) A certificate of an appropriate officer of the Bond Fund as to the
          fulfillment of all agreements and conditions on its part to be
          fulfilled hereunder at or prior to the Closing Date and to the effect
          that the representations and warranties of the Bond Fund are true and
          correct in all material respects at and as of the Closing Date as if
          made at and as of such date; and

       (d) Such other documents, including an opinion of counsel, as the High
          Yield Fund may reasonably request to show fulfillment of the purposes
          and conditions of this Agreement.

     11.

       The obligations of the parties under this Agreement shall be subject to:

       (a) Any required approval, at a meeting duly called for the purpose, of
          the holders of the outstanding shares of the High Yield Fund of this

          this Agreement believes that the consummation of the transactions
          contemplated hereunder would not be in the best interests of its
          shareholders.

                                       29




     12.  Except as expressly provided otherwise in this Agreement, Principal
       Management will pay or cause to be paid all out-of-pocket fees and
       expenses incurred by the High Yield Fund or the Bond Fund in connection
       with the transactions contemplated under this Agreement, including, but
       not limited to, accountants' fees, legal fees, registration fees,
       printing expenses, transfer taxes (if any) and the fees of banks and
       transfer agents. This obligation shall survive the termination or
       expiration of this Agreement regardless of the consummation of the
       transactions contemplated hereunder.

     13.
       This Agreement may be amended by an instrument executed by both the duly
       authorized officers of the Bond Fund and the High Yield Fund at any time,

       the Agreement abandoned at any time prior to the Closing Date, whether
       before or after action thereon by the shareholders of the High Yield Fund
       and notwithstanding favorable action by such shareholders, by mutual
       consent of the Board of Directors of the Bond Fund and the Board of
       Directors of the High Yield Fund. This Agreement may also be terminated
       by action of the Board of Directors of the Bond Fund or the Board of
       Directors of the High Yield Fund (the "Terminating Fund"), if:

       (a) The plan described in the Agreement shall not have become effective

                    NOTES TO PRO FORMA FINANCIAL STATEMENTS
                                  (UNAUDITED)
 -------------------------------------------------------------------------------

1. BASIS OF COMBINATION

On March 11, 2002, the Board of Directors of Principal High Yield Fund, Inc.
approved an Agreement and Plan of Reorganization whereby, subject to approval by
the shareholders of Principal High Yield Fund, Inc., Principal Bond Fund, Inc.
will acquire all the assets of the Principal High Yield Fund, Inc. subject to
the liabilities of such fund, in exchange for a number of shares equal to the
pro rata net assets of shares of the Principal Bond fund, Inc. (the "Merger").

The Merger will be accounted for as a tax-free merger of investment companies.
The pro forma combined financial statements are presented for the information of
the reader and may not necessarily be representative of what the actual combined
financial statements would have been had the reorganization occurred at October
31, 2001. The unaudited pro forma schedule of investments and statement of
assets and liabilities reflect the financial position of the Principal Bond
Fund, Inc. and the Principal High Yield Fund, Inc. at October 31, 2001. The
unaudited pro forma statement of operations reflects the results of operations
of the Principal Bond Fund, Inc. and the Principal High Yield Fund, Inc. for the
year ended October 31, 2001. The statements have been derived from the Funds'
respective books and records utilized in calculating daily net asset value at
the dates indicated above for Principal Bond Fund, Inc. and Principal High Yield
Fund, Inc. under accounting principles generally accepted in the United States.
The historical cost of investment securities will be carried forward to the
surviving entity and results of operations of Principal Bond Fund, Inc. for
pre-combination periods will not be restated.

The pro forma schedule of investments and statements of assets and liabilities
and operations should be read in conjunction with the historical financial
statements of the Funds incorporated by reference in the Statements of
Additional Information.


2. SECURITY VALUATION

Principal Bond Fund, Inc. and Principal High Yield Fund, Inc. value securities
for which market quotations are readily available at market value, which is
determined using the last reported sale price or, if no sales are reported, as
is regularly the case for some securities traded over-the-counter, the last
reported bid price. When reliable market quotations are not considered to be
readily available, which may be the case, for example, with respect to certain
debt securities and preferred stocks, the investments are valued by using prices
provided by market makers or estimates of market values obtained from yield data
and other factors relating to instruments or securities with similar
characteristics in accordance with procedures established in good faith by each
fund's Board of Directors. Securities with remaining maturities of 60 days or
less are valued at amortized cost, which approximates market.


3. CAPITAL SHARES

The pro forma net asset value per share assumes additional shares of common
stock issued in connection with the proposed acquisition of Principal High Yield
Fund, Inc. by Principal Bond Fund, Inc. as of October 31, 2001. The number of
additional shares issued was calculated by dividing the net asset value of each
class of Principal High Yield Fund, Inc. by the respective class net asset value
per share of Principal Bond Fund, Inc.


4. PRO FORMA ADJUSTMENTS

The accompanying pro forma financial statements reflect changes in fund shares
as if the merger had taken place on October 31, 2001. The expenses of the
Principal High Yield Fund, Inc. were adjusted assuming the fee structure of
Principal Bond Fund, Inc. was in effect for the year ended October 31, 2001.


5. DISTRIBUTIONS

No provision for federal income taxes is considered necessary because each fund
is qualified as a "regulated investment company" under the Internal Revenue Code
and intends to distribute each year substantially all of its net investment
income and realized capital gains to shareholders. The cost of investments for
federal income tax reporting purposes approximates that used for financial
reporting purposes.

Principal Bond Fund, Inc. and Principal High Yield Fund, Inc. will distribute
substantially all of their net investment income and any realized gains prior to
the merger date.


6. SUBSEQUENT EVENT

Effective December 28, 2001 and January 31, 2002, Principal Bond Fund, Inc. and
Principal High Yield Fund, Inc. exchanged all Class R shares and Class C shares,
respectively, into Class A shares. The pro forma financial statements do not
reflect the discontinuation of Class C shares and Class R shares.

Item 17. Undertakings.

The undersigned registrant agrees that prior to any public offering of the
securities registered through the use of a prospectus which is a part of this
registration statement by any person or party who is deemed to be an underwriter
within the meaning of Rule 145(c) of the Securities Act [17 CFR 230.145c], the
reoffering prospectus will contain the information called for by the applicable
registration form for reofferings by persons who may be deemed underwriters, in
addition to the information called for by the other items of the applicable
form.

The undersigned registrant agrees that every prospectus that is filed under
paragraph (1) above will be filed as part of an amendment to the registration
statement and will not be used until the amendment is effective, and that, in
determining any liability under the 1933 Act, each post-effective amendment
shall be deemed to be a new registration statement for the securities offered
therein, and the offering of securities at that time shall be deemed to be the
initial bona fide offering of them.

Board of Directors
Principal Bond Fund, Inc.
Des Moines, IA 50392-0200

RE   Registration Statement on Form N-14
     Pursuant to Securities Act of 1933



I am familiar with the proposed issuance by Principal Bond Fund, Inc. of shares
of its Class A common stock, par value $.01 per share and Class B common stock,
par value $.01 per share, in connection with the transfer to it of the assets
and liabilities of Principal High Yield Fund, Inc. pursuant to the terms of an
Agreement and Plan of Acquisition to which they are parties (the "Shares"). I am
also familiar with the above-referenced Registration Statement (the
"Registration Statement") filed with the Securities and Exchange Commission
relating to the offer and sale of Shares. Based upon such investigation as I
have deemed necessary, I am of the opinion that the Shares, when issued in
accordance with the terms described in the Registration Statement, will be
legally issued, fully paid and non-assessable.

I hereby consent to the filing of this opinion as a exhibit to the Registration
Statement.

Very truly yours,



Michael D. Roughton
Counsel

Board of Directors
Principal High Yield Fund, Inc.
711 High Street
Des Moines, IA 50309

RE   Acquisition of Principal High Yield Fund, Inc.
     By Principal Bond Fund, Inc.

To the Board of Directors and Shareholders

Principal Bond Fund, Inc. ("Bond Fund") intends to acquire all of the assets and
assume all of the liabilities of Principal High Yield Fund, Inc. ("High Yield")
in a transaction described in a Form N-14 Registration Statement filed with the
United States Securities and Exchange Commission (the "Registration Statement")
on or about April 5, 2002. You have asked for an opinion concerning the Federal
income tax consequences of the proposed transaction.

Bond Fund is a Maryland Corporation. Continuously since its formation it has
qualified as a regulated investment company for purposes of Subchapter M of the
United States Internal Revenue Code of 1986 (the "Code") and has elected to be
taxed as such.

High Yield is also a Maryland Corporation. High Yield, like Bond Fund, has
qualified since its inception as a regulated investment company for purposes of
the Code, and has elected to be taxed as such.

Bond Fund and High Yield are each an open-end diversified management company
registered with the Securities and Exchange Commission and various states.

Bond Fund will acquire all of the assets of High Yield, and assume all of its
liabilities, in exchange for Bond Fund shares. High Yield will immediately
liquidate and dissolve, distributing the shares of Bond Fund to High Yield
shareholders in retirement of their High Yield shares. Each holder of shares of
High Yield will as a result of the transaction own shares of Bond Fund of equal
value.

In reliance on the information provided in the Registration Statement, I am of
the opinion that:

     1.) The acquisition of all of the assets and liabilities of High Yield by
        Bond Fund in exchange for shares of Bond Fund, followed by distribution
        of those shares of Bond Fund to shareholders of High Yield in
        liquidation of High Yield, will constitute a reorganization within the
        meaning of section 368(a)(1)(C) of the Code.

     2.) Shareholders of High Yield will recognize no gain or loss as a
        consequence of the surrender of their shares of High Yield in exchange
        for shares of Bond Fund pursuant to the liquidation of High Yield. (Code
        Section 354).

     3.) The tax basis and holding period of shares of Bond Fund acquired in
        exchange for shares of High Yield will be the same as the tax basis and
        the holding period of the shares of High Yield exchanged therefore.
        (Code Sections 354 and 1223).

     4.) High Yield will recognize no gain or loss on the transfer of all of its
        assets to Bond Fund. (Code Section 361(a)).

     5.) The tax basis of the assets of High Yield in the hands of Bond Fund
        will be the same as the tax basis of those assets in the hands of High
        Yield immediately prior to the acquisition. (Code Section 362(b)).


                                       43



The foregoing opinions are based on the Code, current Treasury Regulations
issued thereunder, published administrative, interpretations thereof and
judicial decisions with respect thereto (collectively the "Tax Law") as of the
date hereof. No assurance can be given that the Tax Laws will not change.

I hereby consent to the use of this letter as an Exhibit to, and reference to it
in, the Registration Statement.

Sincerely yours



Randy Bergstrom
Counsel to Principal Bond Fund, Inc.
