Dear (INSERT NAME),

We value the investments you have with the Principal Financial Group(R) (The
Principal(R)). By now, you may have heard the news that we plan to strengthen
and expand our retail mutual fund business by combining Principal Mutual Funds
into the Principal Investors Fund.

The Board of Directors of each of our retail mutual funds unanimously approved
this proposal. Shareholders of record as of March 24, 2005, are now being asked
to vote. You should have recently received a proxy statement and voting ballot
in the mail. A shareholder meeting is planned for June 16.

We need your vote to help prevent unnecessary costs.
The proxy solicitation firm will contact shareholders who don't vote their
shares. Each effort to contact these shareholders will result in additional
costs. The costs are borne by the funds and Principal Management Corporation,
which manages the funds. Making multiple contacts to individual shareholders --
or failing to achieve a successful vote -- could lead to higher expenses. That's
why we need you to vote.

Voting is easy.
Voting will only take a few minutes. We urge you to vote as soon as possible by
returning the ballot you received in the mail, visiting the Internet address
provided on the proxy ballot, or calling toll-free 888-999-5346. Refer to the
proxy materials you received in the mail for further instructions. If you can't
locate your proxy materials, you may also call 888-999-5346 for assistance.

Thank you for making time to cast your vote on this important initiative.

Hello, I'm (NAME). I'm calling today because we value the business you have
placed with the Principal Mutual Funds. We want to make sure you understand some
exciting developments we have underway to expand our mutual fund platform.

By now, you've heard the news that we plan to strengthen and expand our retail
mutual fund business by combining Principal Mutual Funds into the existing
Principal Investors Fund. The Board of Directors of each of our retail funds
unanimously approved this proposal. Shareholders of record as of March 24, 2005,
are now being asked for their approval.

Your clients should have recently received a proxy statement and voting ballot
in the mail. I'm calling you today to ask for your assistance. I have here a
list of your clients with high share balances in one or more Principal Mutual
Funds.

We're asking that you contact these clients either by phone or mail and
encourage them to vote. I can send you a pre-approved call script and letter for
this purpose. Your support of this proposal is key to its success, taking a few
minutes to contact your best clients should be well worth your time. Who knows,
it may even lead to additional opportunities.

Every vote is important. The proposal to combine Principal Mutual Funds into
Principal Investors Fund contains several important benefits:
o    Expanded  investment  options - with more fund choices and more  investment
     managers
o    A combined  platform - should bring greater  efficiencies  and  potentially
     lower overall fund expenses

The proxy firm will contact shareholders who don't vote their shares. Each
effort to contact these shareholders will result in additional costs. The costs
are borne by the funds and Principal Management Corporation, which manages the
funds. Making multiple contacts to individual shareholders -- or failing to
achieve a successful vote -- could lead to higher expenses. That's why we need
you to vote.

Voting is easy, and will only take a few minutes. Please urge your clients to
vote as soon as possible by returning the ballot they received in the mail,
visiting the Internet address provided on the proxy ballot, or contacting the
proxy firm by phone.

Thank you for taking the time to talk today, and we look forward to receiving
your clients' votes soon. For additional information, or to vote their shares,
your clients can call the proxy firm at 888-999-5346.
