                              2028 SERIES EE BONDS

           Section 2.1. There shall be a twenty-ninth series of Bonds, known as
and entitled "First Mortgage Bonds, Adjustable Rate Series EE due 2028" or
"First Mortgage Bonds, Adjustable Rate Series EE" (herein and in the Indenture
referred to as the "2028 Series EE Bonds"), and the form thereof shall contain
suitable provisions with respect to the matters hereinafter in this Section
specified and shall in other respects be substantially as set forth in the
preambles to the Original Indenture.

      The aggregate principal amount of 2028 Series EE Bonds which may be
authenticated and delivered and outstanding under the Indenture is Nine Million
Five Hundred Forty-Five Thousand Dollars ($9,545,000).

      The 2028 Series EE Bonds shall be payable to the EDA Loan Trustee, and
shall be nontransferable except to a successor of the EDA Loan Trustee.

      The 2028 Series EE Bonds shall bear interest at the minimum rate per annum
necessary to yield interest in amounts sufficient, when taken together with
other amounts available therefor under the EDA Bond Indenture, to pay the
interest from time to time payable on the 1998A EDA Bonds, computed on the same
basis as the 1998A EDA Bonds (interest on overdue principal and premium, if any,
and, to the extent legally enforceable, interest, being at the rate of six
percent (6%) per annum), but in no event shall the interest rate on the 2028
Series EE Bonds exceed ten percent (10%) per annum; and the 2028 Series EE Bonds
shall mature on January 1, 2028, subject to prior redemption as described
herein. The amount of "annual interest charges" on the 2028 Series EE Bonds,
within the meaning of any provision of the Indenture requiring a determination
of said amount as a condition to the issuance of any Bonds thereunder
(including, without limitation, the 2028 Series EE Bonds), shall mean the amount
calculated by applying to the 2028 Series EE Bonds the interest rate of ten
percent (10%) per annum; provided, however, that if the rate of interest on the
1998A EDA Bonds shall have become fixed and determined at a per annum rate lower
than ten percent (10%) for a period not less than the remaining maturity of said



                                      -11-
   13
1998A EDA Bonds (whether said 1998A EDA Bonds shall mature at their stated
maturity, by earlier redemption or otherwise), then said lower rate shall be
used to determine the amount of the "annual interest charges" on the 2028 Series
EE Bonds.

      The 2028 Series EE Bonds shall be in the form of registered Bonds without
coupons of denominations of Five Thousand Dollars ($5,000) and any integral
multiple thereof which may be authorized by the Company, the issue of a
registered Bond without coupons in any such denomination to be conclusive
evidence of such authorization. The 2028 Series EE Bonds shall be dated as
provided in Section 2.05 of the Indenture. All 2028 Series EE Bonds shall bear
interest from their respective dates, such interest to be payable, upon the
terms of and otherwise in accordance with the 2028 Series EE Bonds, on the first
business day preceding each date on which interest shall from time to time be
payable on the 1998A EDA Bonds; provided, that the obligation of the Company to
make payments with respect to the principal of, premium, if any, and interest on
the 2028 Series EE Bonds shall be fully or partially, as the case may be,
satisfied and discharged to the extent that at the time any such payment shall
be due, the then due principal of, premium, if any, and interest on any of the
1998A EDA Bonds shall have been fully or partially paid from payments made by
the Company under the Loan Agreement or from other moneys expressly available
therefor in the principal and interest account for the 1998A EDA Bonds under the
EDA Bond Indenture or, as far as principal is concerned, reduced by the
principal amount of any of the 1998A EDA Bonds deemed paid pursuant to Article X
of the EDA Bond Indenture. The principal of and the premium, if any, and
interest on the 2028 Series EE Bonds shall be payable at the principal office of
the Trustee, in the City of Chicago, Illinois, or, at the option of the Company,
at the "Principal Office" (as that term is defined in the EDA Bond Indenture) of
the EDA Loan Trustee, in any coin or currency of the United States of America
which at the time of payment shall be legal tender for the payment of public and
private debts.

      Notwithstanding any other provision of the Indenture or of the 2028 Series
EE Bonds, payments of the principal of and the premium, if any, and interest on
any 2028 Series EE Bond may be made directly to the registered holder thereof
without presentation or surrender thereof or the making of any notation thereon
if there shall be filed with the Trustee a Certificate of the Company to the
effect that such registered holder (or the person for whom such registered
holder is a nominee) and the Company have entered into a written agreement that
payment shall be so made; provided, however, that before such registered holder
transfers or otherwise disposes of any 2028 Series EE Bond, such registered
holder will, at its election, either endorse thereon (or on a paper annexed
thereto) the principal amount thereof redeemed and the last date to which
interest has been paid thereon or make such Bond available to the Company at the
principal office of the Trustee for the purpose of making such endorsement
thereon.

      The 2028 Series EE Bonds shall be subject to redemption at the option of
the Company or otherwise, in the manner provided in the applicable provisions of
Article Ten of the Indenture, as amended by Article IV of this Supplemental
Indenture.

      The 2028 Series EE Bonds shall be excluded from the benefits of, and shall
not be subject to redemption through the operation of, a Mandatory Sinking Fund
pursuant to


                                      -12-
   14
Section 11.02 of the Indenture and shall also be excluded from the benefits of
the covenants of Section 9.08 and Section 11.01 of the Indenture.

      Notwithstanding the provisions of Section 10.04 or any other provision of
the Indenture, the selection of 2028 Series EE Bonds to be redeemed shall, in
case fewer than all of the outstanding 2028 Series EE Bonds are to be redeemed,
be made by the Trustee pro rata (to the nearest multiple of Five Thousand
Dollars ($5,000)) among the registered holders of the 2028 Series EE Bonds in
proportion, as nearly as practicable, to the respective unpaid principal amounts
of 2028 Series EE Bonds registered in the names of such holders, with
adjustments, to the extent practicable, to compensate for any prior redemption
not made exactly in such proportion (or otherwise as may be specified by a
written order signed by the registered holders of all outstanding 2028 Series EE
Bonds).

      The definitive 2028 Series EE Bonds may be issued in the form of engraved
Bonds or Bonds printed or lithographed on steel engraved borders or Bonds in
typed form on normal bond paper. Subject to the foregoing provisions of this
Section and the provisions of Section 2.11 of the Indenture, all definitive 2028
Series EE Bonds shall be fully exchangeable for other Bonds of the same series,
of like aggregate principal amounts, and, upon surrender to the Trustee at its
principal office, shall be exchangeable for other Bonds of the same series of a
different authorized denomination or denominations, as requested by the holder
surrendering the same. The Company will execute, and the Trustee shall
authenticate and deliver, registered Bonds without coupons, whenever the same
shall be required for any such exchange.

           Section 2.2. 2028 Series EE Bonds in the aggregate principal amount
of Nine Million Five Hundred Forty-Five Thousand Dollars ($9,545,000) may
forthwith upon the execution and delivery of this Supplemental Indenture, or
from time to time thereafter, be executed by the Company and delivered to the
Trustee, and shall thereupon be authenticated and delivered by the Trustee upon
compliance by the Company with the provisions of Articles Four, Five or Six of
the Indenture, without awaiting the filing or recording of this Supplemental
Indenture. No additional 2028 Series EE Bonds shall be issued under Article
Four, Five or Six without the consent in writing of the holders of all the
outstanding 2028 Series EE Bonds.


                                  ARTICLE III.

                              2028 SERIES FF BONDS

           Section 3.1. There shall be a thirtieth series of Bonds, known as and
entitled "First Mortgage Bonds, Adjustable Rate Series FF due 2028" or "First
Mortgage Bonds, Adjustable Rate Series FF" (herein and in the Indenture referred
to as the "2028 Series FF Bonds"), and the form thereof shall contain suitable
provisions with respect to the matters hereinafter in this Section specified and
shall in other respects be substantially as set forth in the preambles to the
Original Indenture.

percent (6%) per annum), but in no event shall the interest rate on the 2028
Series FF Bonds exceed ten percent (10%) per annum; and the 2028 Series FF Bonds
shall mature on January 1, 2028, subject to prior redemption as described
herein. The amount of "annual interest charges" on the 2028 Series FF Bonds,
within the meaning of any provision of the Indenture requiring a determination
of said amount as a condition to the issuance of any Bonds thereunder
(including, without limitation, the 2028 Series FF Bonds), shall mean the amount
calculated by applying to the 2028 Series FF Bonds the interest rate of ten
percent (10%) per annum; provided, however, that if the rate of interest on the
1998B EDA Bonds shall have become fixed and determined at a per annum rate lower
than ten percent (10%) for a period not less than the remaining maturity of said
1998B EDA Bonds (whether said 1998B EDA Bonds shall mature at their stated
maturity, by earlier redemption or otherwise), then said lower rate shall be
used to determine the amount of the "annual interest charges" on the 2028 Series
FF Bonds.

      The 2028 Series FF Bonds shall be in the form of registered Bonds without
coupons of denominations of Five Thousand Dollars ($5,000) and any integral
multiple thereof which may be authorized by the Company, the issue of a
registered Bond without coupons in any such denomination to be conclusive
