         and cannot rely on the position of the staff of the Commission set
         forth in certain no-action letters;

                  (vii) the undersigned understands that a secondary resale
         transaction described in clause (vi) above and any resales of Exchange
         Securities or interests therein obtained by such holder in exchange for
         Initial Securities or interests therein originally acquired by such
         holder directly from MidAmerican Funding should be covered by an
         effective registration statement containing the selling security holder
         information required by Item 507 or Item 508, as applicable, of
         Regulation S-K of the Commission; and

                  (viii) neither the holder nor any such other person is an
         "affiliate," as such term is defined under Rule 405 promulgated under
         the Securities Act of 1933, as amended (the "Securities Act"), of
         MidAmerican Funding.

         5. The undersigned may, if and only if unable to make all of the
representations and warranties contained in Item 4 above, elect to have its
Initial Securities registered in the shelf registration described in the
Registration Rights Agreement, dated March 9, 1999, among Credit Suisse First
Boston Corporation, Lehman Brothers Inc., Goldman Sachs & Co., Merrill Lynch &
Co. and MidAmerican Funding, in the form filed as an exhibit to the registration
statement of which the Prospectus is a part. Such election may be made by
checking the box under "Special Registration Instructions" on page 9. By making
such election, the undersigned agrees, jointly and severally, as a holder of
transfer restricted securities participating in a shelf registration, to
indemnify and hold harmless MidAmerican Funding, its directors and officers and
each Person who controls MidAmerican Funding, within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act, against any and all
losses, claims, damages and liabilities whatsoever (including, without
limitation, the reasonable legal and other expenses actually incurred in
connection with any suit, action or proceeding or any claim asserted) caused by,
arising out of or based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in the shelf registration statement
filed with respect to such Initial Securities or the related prospectus or in
any amendment thereof or supplement thereto or (ii) the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, in each case to the extent, but only
to the extent, that any such loss, claim, damage or liability arises out of or
is based upon any untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with
information relating to the undersigned furnished to MidAmerican Funding in
writing by or on behalf of the undersigned expressly for use therein. Any such
indemnification shall be governed by the terms and subject to the conditions set
forth in the Registration Rights Agreement, including, without limitation, the
provisions regarding notice, retention of counsel, contribution and payment of
expenses set forth therein.

         6. If the undersigned is not a broker-dealer, the undersigned
represents that it is not engaged in, and does not intend to engage in, a
distribution of Exchange Securities. If the undersigned is a broker-dealer that
will receive Exchange Securities for its own account in exchange for Initial

account were not acquired as a result of market-making or other trading
activities, such Initial Securities cannot be exchanged pursuant to the Exchange
Offer.

         7. Any obligation of the undersigned hereunder shall be binding upon
the successors, assigns, executors, administrators, trustees in bankruptcy and
legal and personal representatives of the undersigned.

                 WHICH FORM A PART OF THIS LETTER OF TRANSMITTAL


                                       10





                                  INSTRUCTIONS

         1. GUARANTEE OF SIGNATURES. Signatures on this Letter of Transmittal
must be guaranteed by an eligible guarantor institution that is a member of or
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program or by an "eligible guarantor
institution" within the meaning of Rule l7Ad-15 promulgated under the Exchange
Act (an "Eligible Institution") unless the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" above has not been completed or
the Initial Securities described above are tendered for the account of an
Eligible Institution.

         2. DELIVERY OF LETTER OF TRANSMITTAL AND INITIAL SECURITIES. The
Initial Securities, together with a properly completed and duly executed Letter
of Transmittal (or copy thereof), should be mailed or delivered to the Exchange
Agent at the address set forth above.

         THE METHOD OF DELIVERY OF INITIAL SECURITIES AND THE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
ELECTION AND RISK OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED
THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT
TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE
EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR INITIAL SECURITIES SHOULD BE SENT
TO MIDAMERICAN FUNDING. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES, OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.

         3. SIGNATURE ON LETTER OF TRANSMITTAL, BOND POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by a person other than a registered holder
of any Initial Securities, such Initial Securities must be endorsed or
accompanied by appropriate bond powers, signed by such registered holder exactly
as such registered holder's name appears on such Initial Securities.

         If this Letter of Transmittal or any Initial Securities or bond powers
are signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations, or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
MidAmerican Funding, proper evidence satisfactory to MidAmerican Funding of its
authority to so act must be submitted with this Letter of Transmittal.

         4. MISCELLANEOUS. All questions as to the validity, form, eligibility
(including time of receipt), acceptance, and withdrawal of tendered Initial
Securities will be determined by MidAmerican Funding in its sole discretion,
which determination will be final and binding on all parties. The Registrant
reserves the absolute right to reject any or all Initial Securities not properly
tendered or any Initial Securities MidAmerican Funding's acceptance of which
would, in the opinion of counsel for MidAmerican Funding, be unlawful. The
Registrant also reserves the right to waive any defects, irregularities, or
conditions of tender as to particular Initial Securities. The Registrant's
interpretation of the terms and conditions of the Exchange Offer


                                       11


(including the instructions in this Letter of Transmittal) will be final and
binding. Unless waived, any defects or irregularities in connection with tenders
of Initial Securities must be cured within such time as MidAmerican Funding
shall determine. Neither MidAmerican Funding, the Exchange Agent, nor any other
person shall be under any duty to give notification of defects in such tenders
or shall incur any liability for failure to give such notification. Tenders of
Initial Securities will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Initial Securities received by the
Exchange Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering holder thereof as soon as practicable following the
Expiration Date.
