                                   ARTICLE TWO

                        TITLE AND TERMS OF THE SECURITIES

     SECTION 2.01. Title of the Securities; Stated Maturity. This Supplemental
Indenture hereby establishes two separate series of Securities, which shall be
known as the Company's "5.45% Senior Notes due 2032" (the "5.45% Notes"), and
the "5.25% Senior Notes due 2032" (the "5.25% Notes" and together with the 5.45%
Notes, the "Notes"). For purposes of the Original Indenture, each series of the
Notes shall separately constitute a single series of Securities. The Stated
Maturity on which the principal of the 5.45% Notes shall be due and payable will
be December 15, 2032. The Stated Maturity on which the principal of the 5.25%
Notes shall be due and payable will be December 15, 2032. The 5.45% Notes are
being issued to secure the Company's obligations to XLCA under the 2002C
Insurance Agreement and the 5.25% Notes are being issued to secure the Company's
obligations to XLCA under the 2002D Insurance Agreement.

     SECTION 2.02. Certain Variations from the Original Indenture. (a) The Notes

subject, in each case, to the release provisions provided for in Section 4.02
herein. In addition, on and after the Release Date, unless Substitute Mortgage
Bonds are issued to secure the Notes, the Notes shall have the benefit of the
additional covenants set forth in Article Three hereof.

     (b)   In the event the Company desires to provide for the payment of 5.45%
Senior Notes, in lieu of defeasing such Notes in accordance with Section 5.03 of
the Original Indenture, it shall either redeem an equal principal amount of the
2002C Bonds or take such action as shall be required by Section 2.04 of the
2002C Bond Indenture to defease an equal principal amount of the 2002C Bonds.
Pursuant to Section 2.03(c) hereof, such redemption or defeasance shall result
in the discharge of the Company's obligation with respect to such 5.45% Senior
Notes and the cancellation of such 5.45% Senior Notes.

     (c)   In the event the Company desires to provide for the payment of 5.25%
Senior Notes, in lieu of defeasing such Notes in accordance with Section 5.03 of
the Original Indenture, it shall either redeem an equal principal amount of the
2002D Bonds or take such action as shall be required by Section 2.04 of the
2002D Bond Indenture to defease an equal principal amount of the 2002D Bonds.
Pursuant to Section 2.03(c) hereof, such redemption or defeasance shall result
in the discharge of the Company's obligation with respect to such 5.25% Senior
Notes and the cancellation of such 5.25% Senior Notes.

     (d)   Any amount payable by the Company in respect of principal of 5.45%
Senior Notes whether at maturity or prior to maturity by redemption or upon
redemption or acceleration or otherwise, in a circumstance where there has not
been a corresponding payment of principal of 2002C Bonds shall be applied
simultaneously to the redemption or defeasance of any equal

                                       4

<PAGE>

principal amount of 2002C Bonds in accordance with the 2002C Bond Indenture. In
the event the amount so paid is insufficient to provide for such redemption or
defeasance, the Company shall pay such additional amounts as shall be necessary
to make up the deficiency.

     (e)   Any amount payable by the Company in respect of principal of 5.25%
Senior Notes whether at maturity or prior to maturity by redemption or upon
redemption or acceleration or otherwise, in a circumstance where there has not
been a corresponding payment of principal of 2002 D Bonds shall be applied
simultaneously to the redemption or defeasance of any equal principal amount of
2002D Bonds in accordance with the 2002D Bond Indenture. In the event the amount
so paid is insufficient to provide for such redemption or defeasance, the
Company shall pay such additional amounts as shall be necessary to make up the
deficiency

     SECTION 2.03. Amount, Assignability and Redemption.

     (a)   The aggregate principal amount of Notes that may be issued under this
Supplemental Indenture is limited to $64,300,000 in the case of the 5.45% Notes
and $55,975,000 in the case of the 5.25% Notes (except, in each case, as
provided in Section 301(2) of the Original Indenture). The Notes shall be
issuable only in fully registered form and, as permitted by Section 301 and
Section 302 of the Original Indenture, in denominations of $1,000 and integral
multiples thereof to XLCA. The Notes shall not be assignable or transferable
except as may be required to effect a transfer to any successor insurer for the
2002C Bonds or the 2002D Bonds, as the case may be.

     (b)   The Notes may bear such legends as may be necessary to refer to the
2002C Insurance Agreement or 2002D Insurance Agreement, as the case may be,
between the Company and XLCA or to comply with any law or with any rules or
regulations made pursuant thereto or to evidence the limited assignability.

     (c)   Upon payment of the principal or premium, if any, or interest on the
2002C Bonds or the 2002D Bonds, as the case may be, whether at maturity or prior
to maturity by redemption or otherwise, or upon provision for the payment
thereof having been made in accordance with Article I or IV of the 2002C Bond
Indenture or the 2002D Bond Indenture, with respect to the 2002C Bonds or the
2002D Bonds, as the case may be, Notes in a principal amount equal to the
principal amount of the related Bonds shall, to the extent of such payment of
principal, premium or interest, be deemed fully paid and the obligation of the
Company thereunder to make such payment shall forthwith cease and be discharged,
and, in the case of the payment of principal and premium, if any, such Notes
shall be surrendered for cancellation or presented for appropriate notation to
the Trustee.

     (d)   The Notes shall be redeemed on the dates and in the respective
principal amounts which correspond to the redemption date for, and the principal
amount to be redeemed of, the 2002C Bonds or the 2002D Bonds, as the case may
be.

     (e)   In the event of an Event of Default under a Bond Indenture and the
acceleration of the 2002C Bonds or the 2002D Bonds, as the case may be, the
related Notes shall be redeemable in whole upon receipt by the Trustee of a
written demand (Redemption Demand) from XLCA indicating that it has paid the
accelerated principal.

     SECTION 2.04. Certain Common Terms of the Notes.

                                       5

<PAGE>

     (a)   The 5.45% Notes shall bear interest at the rate of 5.45% per annum,
and the 5.25% Notes shall bear interest at the rate of 5.25% per annum, in each
case on the respective principal amount thereof, from December 5, 2002, or from
the most recent Interest Payment Date to which interest has been paid or duly
provided for, until the principal of such series of Notes becomes due and
payable, and on any overdue principal and premium and (to the extent that
payment of such interest is enforceable under applicable law) on any overdue
installment of interest at the same rate per annum during such overdue period.
Interest on the Notes will be payable semiannually in arrears on June 15 and
December 15 of each year (each such date, an "Interest Payment Date"),
commencing June 15, 2003. Payment of interest on the 2002C Bonds and the 2002D
Bonds shall be deemed to constitute payment on the related series of Notes. The
amount of interest payable for any period shall be computed on the basis of
twelve 30-day months and a 360-day year.

     (b)   In the event that any Interest Payment Date, redemption date or other
date of Maturity of the Notes is not a Business Day, then payment of the amount
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay), in
each case with the same force and effect as if made on such date. The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date with respect to any Note will, as provided in the Original
Indenture, be paid to the person in whose name the Note (or one or more
Predecessor Securities, as defined in said Indenture) is registered at the close
of business on the relevant record date for such interest installment, which
shall be the fifteenth calendar day (whether or not a Business Day) prior to the
relevant Interest Payment Date (the "Regular Record Date"). Any such interest
installment not punctually paid or duly provided for shall forthwith cease to be
payable to the registered Holders on such Regular Record Date, and may either be
paid to the person in whose name the Note (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date to
be fixed by the Trustee for the payment of such defaulted interest, notice
whereof shall be given to the registered Holders of the applicable series of
Notes not less than ten days prior to such Special Record Date, or may be paid
at any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Notes may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the Original
Indenture. The principal of, and premium, if any, and the interest on the Notes
shall be payable at the office or agency of the Company maintained for that
purpose in the Borough of Manhattan, The City of New York, in any coin or
currency of the United States of America that at the time of payment is legal
tender for payment of public and private debts; provided, however, that payment
of interest may be made at the option of the Company by check mailed to the
registered Holder at the close of business on the Regular Record Date at such
address as shall appear in the Security Register.

     (c)   The Notes are not subject to repayment at the option of the Holders
thereof and are not subject to any sinking fund, except to the extent that XLCA,
or its successor in interest, may have exercised its rights pursuant to Section
2.03 hereof. As provided in the forms of Note attached hereto as Exhibit A and
Exhibit B, respectively, the Notes are subject to optional redemption, as a
whole or in part, by the Company prior to Stated Maturity of the principal
thereof upon the same terms as the 2002C Bonds and the 2002D Bonds, as the case
may be. Except as modified in the forms of the Notes, redemptions shall be
effected in accordance with Article Twelve of the Original Indenture.

     (d)   The Notes shall have such other terms and provisions as are set forth
in the form of Note attached hereto as Exhibit A and Exhibit B, as applicable
(each of which are incorporated by reference in and made a part of this
Supplemental Indenture as if set forth in full at this place).

                                       6

<PAGE>

     SECTION 2.05. Form of Notes. Attached hereto as Exhibit A is the form of
the definitive 5.45% Notes. Attached hereto as Exhibit B is the form of the
definitive 5.25% Notes. If the Company elects to have the Notes secured by
Substitute Mortgage Bonds on and after the Release Date, the terms of the Notes
shall be amended to make appropriate reference to the Substitute Mortgage and
the Substitute Mortgage Bonds; provided, that the consent of Holders shall not
be required in connection with such amendment.

                                  ARTICLE THREE

                              ADDITIONAL COVENANTS

     SECTION 3.01. Limitations on Liens. (a) From and after the Release Date,
unless Substitute Mortgage Bonds are issued to secure the Notes, so long as any
Notes are outstanding, the Company may not issue, assume, guarantee (including
any contingent obligation to purchase) or permit to exist any Debt that is
secured by any mortgage, security interest, pledge or lien ("Lien") of or upon
any Operating Property owned by the Company, whether owned at the Release Date
or subsequently acquired, without effectively securing the Notes (together with,
if the Company shall so determine, any other indebtedness of the Company ranking
equally with the Notes) equally and ratably with the Debt (but only so long as
the Debt is so secured).

     The foregoing restriction will not apply to:

     (i)   Liens on any Operating Property existing at the time of its
           acquisition and not created in contemplation of the acquisition;

     (ii)  Liens on Operating Property of a corporation existing at the time the
           corporation is merged into or consolidated with the Company, or at
           the time the corporation disposes of substantially all of its
           properties (or those of a division) to the Company, provided that the
           Lien is not extended to property owned by the Company immediately
           prior to the merger, consolidation or other disposition and is not
           created in contemplation of the merger, consolidation or other
           disposition;

     (iii) Liens on Operating Property to secure the cost of acquisition,
           construction, development or substantial repair, alteration or
           improvement of such property or to secure indebtedness incurred to
           provide funds for any of these purposes or for reimbursement of funds
           previously expended for any of these purposes, provided the Liens are
           created or assumed contemporaneously with, or within 18 months after,
           the acquisition or the completion of substantial repair or
           alteration, construction, development or substantial improvement or
           within 6 months thereafter pursuant to a commitment for financing
           arranged with a lender or investor within such 18-month period;

     (iv)  Liens in favor of the United States or any state or any department,
           agency or instrumentality or political subdivision of the United
           States or any state, or for the benefit of holders of securities
           issued by any of these entities, to secure any Debt incurred for the
           purpose of financing all or any part of the purchase price or the
           cost of substantially repairing or altering, constructing, developing
           or substantially improving the Operating Property of the Company; or

     (v)   Any extension, renewal or replacement (or successive extensions,
           renewals or replacements), in whole or in part, of any Lien referred
           to in the exceptions listed above,

                                       7

<PAGE>

          provided, however, that the principal amount of Debt secured thereby
          and not otherwise authorized by those exceptions listed above shall
          not exceed the principal amount of Debt, plus any premium or fee
          payable in connection with any such extension, renewal or replacement,
          so secured at the time of such extension, renewal or replacement.

     (b)  In addition, notwithstanding the foregoing restrictions, from and
after the Release Date, the Company may issue, assume or guarantee Debt secured
by a Lien which would otherwise be subject to the foregoing restrictions up to
an aggregate amount which, together with all other of the Company's secured Debt
(not including secured Debt permitted under any of the foregoing exceptions) and
the Value of Sale and Lease-Back Transactions existing at such time (other than
Sale and Lease-Back Transactions the proceeds of which have been applied to the
retirement of certain indebtedness, Sale and Lease-Back Transactions in which
the property involved would have been permitted to be subjected to a Lien under
any of the foregoing exceptions, and Sale and Lease-Back Transactions that are
permitted by the first sentence of Section 3.02 below), does not exceed the
greater of 10% of the Company's Net Tangible Assets or 10% of the Company's
Capitalization. The foregoing restrictions do not limit the Company's ability to
place Liens on (i) the capital stock of any of the Company's subsidiaries or
(ii) the assets of any of the Company's subsidiaries.

     SECTION 3.02. Limitations on Sale and Lease-Back Transactions. So long as
the Notes are outstanding from and after the Release Date, unless Substitute
Mortgage Bonds are issued to secure the Notes, the Company may not enter into or
permit to exist any Sale and Lease-Back Transaction with respect to any
Operating Property (except for leases for a term, including any renewal or
potential renewal, of not more than 48 months), if the purchaser's commitment is
obtained more than 18 months after the later of the completion of the
acquisition, construction or development of the Operating Property or the
placing in operation of the Operating Property or of the Operating Property as
constructed or developed or substantially repaired, altered or improved. This
restriction will not apply if (a) the Company would be entitled pursuant to
Section 3.01(a) above to issue, assume, guarantee or permit to exist Debt
secured by a Lien on the Operating Property without equally and ratably securing
the Notes, (b) after giving effect to the Sale and Lease-Back Transaction,
pursuant to Section 3.01(b) above, the Company could incur, at least $1.00 of
additional Debt secured by Liens (other than Liens permitted by clause (a)), or
(c) the Company applies within 180 days an amount equal to, in the case of a
sale or transfer for cash, the net proceeds (not less than the fair value of the
Operating Property so leased), and, otherwise, an amount equal to the fair value
(as determined by the Board of Directors of the Company) of the Operating
Property so leased to the retirement of Notes or other Debt of the Company
ranking equally with the Notes; provided, however, that any such retirement of
Notes shall be in accordance with the terms and provisions of the Indenture and
the Notes; provided, further, that the amount to be applied to such retirement
of Notes or other Debt shall be reduced by an amount equal to the sum of (a) an
amount equal to the redemption price with respect to Notes delivered within such
one hundred eighty (180)-day period to the Trustee for retirement and
cancellation and (b) the principal amount, plus any premium or fee paid in
connection with any redemption in accordance with the terms of other Debt
voluntarily retired by the Company within such one hundred eighty (180)-day
period, excluding in each case retirements pursuant to mandatory sinking fund or
prepayment provisions and payments at maturity.

     SECTION 3.03. Waiver. Section 1109 of the Original Indenture shall apply to
the covenants set forth in Sections 3.01 and 3.02 above at any time such
covenants are in effect.

                                  ARTICLE FOUR

                         SECURITY AND RELEASE PROVISIONS

     SECTION 4.01. Security. Subject to Section 4.02 below, as provided in and
pursuant to Article Four of the Original Indenture, each series of the Notes
will be secured as to payments of principal, interest and premium, if any, by a
series of Mortgage Bonds (the "General and Refunding Mortgage Bonds, 2002 Series
C", in the case of the 5.45% Notes, and the "General and Refunding Mortgage
Bonds, 2002 Series D", in the case of the 5.25% Notes, or, singly or
collectively, the "Bonds," the "Bonds of the related series" or the "related
series of Bonds") of the Company to be issued concurrently with the issuance of
the Notes under and secured by a Mortgage and Deed of Trust, dated as of October
1, 1924, between the Company and Bank One, National Association, as successor
trustee (the "Mortgage Trustee"), as amended and supplemented by various
supplemental indentures, including the supplemental indenture, dated as of
December 1, 2002, creating the Bonds (collectively, the "Mortgage"), pledged by
the Company for the benefit of the Holders of the respective series of Notes to
the Trustee under this Supplemental Indenture. The Bonds shall be issued in an
aggregate principal amount equal to the aggregate principal amount of the Notes.

     SECTION 4.02. Release. Until the Release Date and subject to Article Four
of the Original Indenture, the Bonds of the related series issued and delivered
to the Trustee shall serve as security for any and all obligations of the
Company under all Notes of the applicable series from time to time Outstanding,
including, but not limited to (1) the full and prompt payment of the principal
and premium, if any, on such Notes when and as the same shall become due and
payable in accordance with the terms and provisions of the Indenture or such
Notes, either at the Stated Maturity thereof, upon acceleration of the maturity
thereof, upon redemption, or otherwise, and (2) the full and prompt payment of
any interest on such Notes when and as the same shall become due and payable in
accordance with the terms and provisions of this Indenture or the Notes
including, if and to the extent provided for in such Notes, interest on overdue
installments of principal and (to the extent permitted by law) interest on
overdue installments of interest.

     Each supplemental indenture to the Mortgage pursuant to which any Bonds are
issued shall contain a provision to the effect that any payment by the Company
hereunder of principal of or premium or interest on Notes which shall have been
authenticated and delivered in connection with the issuance and delivery to the
Trustee of such Bonds (other than by the application of the proceeds of a
payment in respect of such Bonds) shall to the extent thereof, be deemed to
satisfy and discharge the obligation of the Company, if any, to make a payment
of principal, premium or interest, as the case may be, in respect of such Bonds
which is then due.

     Notwithstanding anything in the Original Indenture to the contrary, from
and after the Release Date, the obligation of the Company to make payment with
respect to the principal of and premium, if any, and interest on the Bonds shall
be deemed satisfied and discharged as provided in the supplemental indenture or
indentures to the Mortgage creating such Bonds and the Bonds shall cease to
secure in any manner Notes theretofore or subsequently issued; the Trustee shall
thereupon surrender the Bonds to the Mortgage Trustee for cancellation and
execute and deliver such proper instruments of release as may be required. From
and after the Release Date, all Notes, whether theretofore or subsequently
issued, shall, at the Company's option, either (i) become unsecured or (ii) be
secured by Substitute Mortgage Bonds pursuant to Section 4.03 below, and any
conditions to the issuance of Notes that refer or relate to Bonds or the
Mortgage shall be

                                        9

<PAGE>

inapplicable (except as such conditions shall be deemed to refer to Substitute
Mortgage Bonds or a Substitute Mortgage pursuant to Section 4.03 below). From
and after the Release Date, the Company shall not issue any additional Mortgage
Bonds, including Pledged Bonds, under the Mortgage. Notice of the occurrence of
the Release Date shall be given by the Trustee to the Holders of the Notes in
the manner provided for in the Original Indenture not later than 30 days after
the Company notifies the Trustee of the occurrence of the Release Date.

     In connection with the establishment of the occurrence of the Release Date,
the Trustee shall be entitled to receive, may presume the correctness of, and
shall be fully protected in relying upon, an Officers' Certificate designating
the Release Date and stating that the conditions to the occurrence of the
Release Date have been satisfied.

     When the obligation of the Company to make payments with respect to the
principal of, and premium, if any, and interest on all or any part of the Bonds
shall be satisfied or deemed satisfied pursuant to the Original Indenture or
pursuant to this Supplemental Indenture, the Trustee shall, upon written request
of the Company, deliver to the Company without charge therefor all of the Bonds
so satisfied or deemed satisfied, together with such appropriate instruments of
transfer or release as may be reasonably requested by the Company. All Bonds
delivered to the Company in accordance with this Section shall be delivered by
the Company to the Mortgage Trustee for cancellation.

     SECTION 4.03. Substitute Mortgage Bonds.

     (a)   The Company shall notify the Trustee not less than 90 days prior to
the Release Date (or such shorter period as the Company and the Trustee may
agree) that the Company has determined to deliver to the Trustee on the Release
Date Substitute Mortgage Bonds in an aggregate principal amount equal to the
aggregate principal amount of Notes and any other Securities subject to the
release provisions Outstanding on the Release Date, in trust for the benefit of
the Holders from time to time of the Notes and any other Securities subject to
the release provisions issued under the Original Indenture, as supplemented, as
security for any and all obligations of the Company under the Notes and any
other Securities subject to the release provisions, including but not limited
to, (1) the full and prompt payment of the principal of and premium, if any, on
the Notes and any other Securities subject to the release provisions when and as
the same shall become due and payable in accordance with the terms and
provisions of the Original Indenture, as supplemented, or the Notes or such
other Securities subject to the release provisions, either at the stated
maturity thereof, upon acceleration of the maturity thereof or upon redemption,
and (2) the full and prompt payment of any interest on the Notes and any other
Securities subject to the release provisions when and as the same shall become
due and payable in accordance with the terms and provisions of the Original
Indenture, as supplemented, or the Notes or such other Securities subject to the
release provisions.

     (b)   The Substitute Mortgage Bonds to be delivered pursuant to the notice
described in Section 4.03(a) shall be delivered in separate series and issues
corresponding to the series and issues of Notes and other Securities subject to
the release provisions Outstanding on the Release Date, each series or issue of
Substitute Mortgage Bonds having the same stated rate or rates of interest (or
interest calculated in the same manner), Interest Payment Dates, stated maturity
date and redemption provisions, and in the same aggregate principal amount, as
the related series or issue of Notes or other Securities subject to the release
provisions outstanding on the Release Date. The Company shall enter into a
Substitute Mortgage for the issuance of Substitute Mortgage Bonds, and designate
it as such in the notice.

                                       10

<PAGE>

     (c)   The notice described in Section 4.03(a) shall also state that on the
Release Date the Company shall deliver to the Trustee a supplemental indenture
to the Original Indenture that will provide, among other things, that upon the
issuance of Notes and other Securities subject to the release provisions on or
after the Release Date, the Company shall deliver to the Trustee in trust for
the benefit of the Holders as described in Section 4.03(a) hereof, and the
Trustee shall accept therefor, related series of Substitute Mortgage Bonds
registered in the name of the Trustee and conforming to the requirements therein
specified.

     (d)   The determination whether to deliver Substitute Mortgage Bonds shall
be made in the Company's sole discretion and without any obligation to do so.

     (e)   In the event that the Company does not deliver the notice described
in Section 4.03(a), the Notes and other Securities subject to the release
provisions Outstanding on the Release Date shall, as of the Release Date, no
longer be entitled to the benefit of the pledge of the Pledged Bonds and shall
thereafter be general unsecured obligations of the Company.

     (f)   Article Four and related provisions of the Original Indenture shall
apply to Substitute Mortgage Bonds pledged to the Trustee hereunder and the
provisions thereof shall be deemed to refer to the Substitute Mortgage and the
Substitute Mortgage Bonds. If the Company elects to have the Notes secured by
Substitute Mortgage Bonds on and after the Release Date, Article Four and
related provisions may be amended to make appropriate reference to the
Substitute Mortgage and the Substitute Mortgage Bonds; provided, that the
consent of Holders shall not be required in connection with such amendment.

     SECTION 4.04. Events of Default.

     (a)   On and after the Release Date, Section 601(8) of the Original
Indenture shall no longer apply to the Notes.

     (b)   On and after the Release Date, if the Notes become secured by
Substitute Mortgage Bonds pursuant to Section 4.03 above, the occurrence of a
"default" (as defined in the Substitute Mortgage) shall constitute an Event of
Default under Section 601 of the Original Indenture with respect to the Notes
and the references in Section 601(4) of the Original Indenture and related
provisions to "Mortgage Bonds" shall be deemed to refer to "Substitute Mortgage
Bonds."

                                  ARTICLE FIVE

                            MISCELLANEOUS PROVISIONS

issued under the Trust Indenture dated as of December 1, 2002 (the "2002C Bond
Indenture") between Michigan Strategic Fund and Bank One Trust Company, National

Special Record Date for the payment of such defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Notes of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any

     This Note shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

     Unless the Certificate of Authentication hereon has been executed by the
Trustee or a duly appointed Authentication Agent referred to herein, this Note
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

     This Note is one of a duly authorized series of Securities of the Company
(herein sometimes referred to as the "Notes"), specified in the Indenture, all
issued or to be issued in one or more series under and pursuant to a Collateral
Trust Indenture dated as of June 30, 1993 (the "Original Indenture") duly
executed and delivered between the Company and Bank One Trust Company, National
Association, as Trustee (herein referred to as the "Trustee"), as supplemented
through and including an Eleventh Supplemental Indenture dated as of December 1,
2002 (together with the Original Indenture, the "Indenture") between the Company
and the Trustee, to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the respective rights, limitations
of rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the registered Holders of the Notes and of the terms upon which the
Notes are, and are to be, authenticated and delivered.

     The Notes are not subject to repayment at the option of the Holders thereof
and are not subject to any sinking fund, except to the extent that XLCA, or its
successor in interest, may have exercised its rights pursuant to Section 2.03 of
the aforesaid Eleventh Supplemental Indenture. The Notes are subject to optional
redemption, as a whole or in part, by the Company prior to Stated Maturity of
the principal thereof upon the same terms as the 2002C Bonds are subject to
redemption. Upon payment of the principal or premium, if any, on the 2002C
Bonds, whether at maturity or prior to maturity by redemption or otherwise, or
upon provision for the payment thereof having been made in accordance with
Article I or IV of the 2002C Bond Indenture, or upon payment of interest on the
2002C Bonds, Notes in a principal amount equal to the principal amount of the
2002C Bonds so paid, or interest on Notes in an amount equal to the interest on
the 2002C Bonds so paid, as the case may be, shall, to the extent of such
payment, be deemed fully paid and the obligation of the Company thereunder to
make such payment shall forthwith crease and be discharged, and, in the case of
the payment of principal and premium, if any, such Notes shall be surrendered
for cancellation or presented for appropriate notation to the Trustee.

     Notwithstanding the foregoing, installments of interest on this Note that
are due and payable on Interest Payment Dates falling on or prior to a
Redemption Date will be payable on the Interest Payment Date to the registered
Holders as of the close of business on the relevant Record Date.

     Notice of any optional redemption will be mailed at least 30 days but not
more than 60 days before the Optional Redemption Date to the Holder hereof at
its registered address.

     Unless the Company defaults in payment of the applicable Redemption Price,
on and after the applicable Redemption Date interest will cease to accrue on the
principal amount of this Note called for redemption.

     If money sufficient to pay the applicable Redemption Price with respect to
the principal amount of and accrued interest on the principal amount of this
Note to be redeemed on the applicable Redemption Date is deposited with the
Trustee or Paying Agent on or before the related

                                       16

<PAGE>

Redemption Date and certain other conditions are satisfied, then on or after
such date, interest will cease to accrue on the principal amount of this Note
called for redemption.

     If the Notes are only partially redeemed by the Company, the Trustee shall
select which Notes are to be redeemed in a manner it deems fair and appropriate
in accordance with the terms of the Indenture.

     In the event of redemption of this Note in part only, a new Note or Notes
of this series for the unredeemed portion hereof will be issued in the name of
the registered Holder hereof upon the cancellation hereof.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Notes may be declared,
and upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Note upon compliance by the Company with certain conditions
set forth therein. In the event the Company desires to provide for the payment
of Notes, in lieu of defeasing the Notes in accordance with the Indenture, the
Company shall either redeem an equal principal amount of 2002C Bonds or take
such action as shall be required by the 2002C Bond Indenture to defease an equal
principal amount of 2002C Bonds.

     Any amount payable by the Company in respect of principal of the Notes,
whether at maturity or prior to maturity by redemption or otherwise, in a
circumstance where there has not been a corresponding payment of principal of
2002C Bonds shall be applied simultaneously to the redemption or defeasance of
any equal principal amount of 2002C Bonds in accordance with the 2002C Bond
Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the registered Holders of not less than a majority in
aggregate principal amount of the outstanding Securities of each series affected
at the time, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or of any supplemental indenture or of
modifying in any manner the rights of the registered Holders of the Securities;
provided, however, that no such supplemental indenture shall (i) extend the
fixed maturity of any Securities of any series, or reduce the principal amount
thereof, or reduce the rate of or extend the time of payment of interest
thereon, or reduce any premium payable upon the redemption thereof, without the
consent of the registered Holder of each Security so affected or (ii) reduce the
aforesaid percentage of Securities, the registered Holders of which are required
to consent to any such supplemental indenture, without the consent of the
registered Holders of each Security then outstanding and affected thereby. The
Indenture also contains provisions permitting (i) the registered Holders of at
least 66 2/3% in aggregate principal amount of the Securities of all series at
the time outstanding affected thereby, on behalf of the registered Holders of
the Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and (ii) the registered Holders of a majority in
aggregate principal amount of the Securities of all series at the time
outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive certain past defaults under the Indenture
and their consequences. Any such consent or waiver by the registered Holder of
this Note (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such registered Holder and upon all future registered Holders and
owners of this Note and of any Note issued in exchange hereof or in place

                                       17

the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the time and place and at the rate and in the coin or currency herein
prescribed.

     Prior to the Release Date, the Notes of this series shall be secured by a
series of Mortgage Bonds (the "Related Series of Bonds"), delivered by the
Company to the Trustee for the benefit of the Holders of the Notes. Reference is
made to the Mortgage and the Indenture for a description of the rights of the

pledged under the Mortgage and the rights of the Company and of the Mortgage
Trustee in respect thereof, the duties and immunities of the Mortgage Trustee
and the terms and conditions upon which the Related Series of Bonds are secured
and the circumstances under which additional Mortgage Bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL BONDS, OTHER THAN (1) PLEDGED BONDS,
INCLUDING THE RELATED SERIES OF BONDS, AND (2) MORTGAGE BONDS (EXCLUSIVE OF
PLEDGED BONDS), WHICH DO NOT IN AGGREGATE PRINCIPAL AMOUNT EXCEED THE GREATER OF
FIVE PERCENT (5%) OF NET TANGIBLE ASSETS OR FIVE PERCENT (5%) OF CAPITALIZATION,
HAVE BEEN RETIRED THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE
MORTGAGE BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH
THE MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF, PROVIDED THAT NO DEFAULT
OR EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING (THE "RELEASE DATE"), THE
RELATED SERIES OF BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Security Register of the
Company, upon surrender of this Note for registration of transfer at the office
or agency of the Company in any place where the principal of and any interest on

designate, duly endorsed by or accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Security
Registrar or any transfer agent duly executed by the registered Holder hereof or
his or her attorney duly authorized in writing, and thereupon one or more new
Notes of this series and of like tenor, of authorized denominations and for the
same aggregate principal amount will be issued to the designated transferee or
transferees. No service charge will be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

     Prior to due presentment for registration of transfer of this Note, the
Company, the Trustee, any paying agent and any Note Registrar may deem and treat

Note shall be overdue and notwithstanding any notice of ownership or writing
hereon made by anyone other than the Note Registrar) for the purpose of
receiving payment of or on account of the principal hereof and interest due
hereon and for all other purposes, and neither the Company nor the Trustee nor
any Paying Agent nor any Security Registrar shall be affected by any notice to
the contrary.

issued under the Trust Indenture dated as of December 1, 2002 (the "2002D Bond
Indenture") between Michigan Strategic Fund and Bank One Trust Company, National
Association, as trustee. Except as otherwise provided in the Indenture, any such

Person in whose name this Note is registered at the close of business on a
Special Record Date for the payment of such defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Notes of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any

     This Note shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

     Unless the Certificate of Authentication hereon has been executed by the
Trustee or a duly appointed Authentication Agent referred to herein, this Note
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

     This Note is one of a duly authorized series of Securities of the Company
(herein sometimes referred to as the "Notes"), specified in the Indenture, all
issued or to be issued in one or more series under and pursuant to a Collateral
Trust Indenture dated as of June 30, 1993 (the "Original Indenture") duly
executed and delivered between the Company and Bank One Trust Company, National
Association, as Trustee (herein referred to as the "Trustee"), as supplemented
through and including an Eleventh Supplemental Indenture dated as of December 1,
2002 (together with the Original Indenture, the "Indenture") between the Company
and the Trustee, to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the respective rights, limitations
of rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the registered Holders of the Notes and of the terms upon which the
Notes are, and are to be, authenticated and delivered.

     The Notes are not subject to repayment at the option of the Holders thereof
and are not subject to any sinking fund, except to the extent that XLCA, or its
successor in interest, may have exercised its rights pursuant to Section 2.03 of
the aforesaid Eleventh Supplemental Indenture. The Notes are subject to optional
redemption, as a whole or in part, by the Company prior to Stated Maturity of
the principal thereof upon the same terms as the 2002D Bonds are subject to
redemption. Upon payment of the principal or premium, if any, on the 2002D
Bonds, whether at maturity or prior to maturity by redemption or otherwise, or
upon provision for the payment thereof having been made in accordance with
Article I or IV of the 2002D Bond Indenture, or upon payment of interest on the
2002D Bonds, Notes in a principal amount equal to the principal amount of the
2002D Bonds so paid, or interest on Notes in an amount equal to the interest on
the 2002D Bonds so paid, as the case may be, shall, to the extent of such
payment of principal, premium or interest, be deemed fully paid and the
obligation of the Company thereunder to make such payment shall forthwith crease
and be discharged, and, in the case of the payment of principal and premium, if
any, such Notes shall be surrendered for cancellation or presented for
appropriate notation to the Trustee.

     Notwithstanding the foregoing, installments of interest on this Note that
are due and payable on Interest Payment Dates falling on or prior to a
Redemption Date will be payable on the Interest Payment Date to the registered
Holders as of the close of business on the relevant Record Date.

     Notice of any optional redemption will be mailed at least 30 days but not
more than 60 days before the Optional Redemption Date to the Holder hereof at
its registered address.

     Unless the Company defaults in payment of the applicable Redemption Price,
on and after the applicable Redemption Date interest will cease to accrue on the
principal amount of this Note called for redemption.

     If money sufficient to pay the applicable Redemption Price with respect to
the principal amount of and accrued interest on the principal amount of this
Note to be redeemed on the applicable Redemption Date is deposited with the
Trustee or Paying Agent on or before the related

                                       23

<PAGE>

Redemption Date and certain other conditions are satisfied, then on or after
such date, interest will cease to accrue on the principal amount of this Note
called for redemption.

     If the Notes are only partially redeemed by the Company, the Trustee shall
select which Notes are to be redeemed in a manner it deems fair and appropriate
in accordance with the terms of the Indenture.

     In the event of redemption of this Note in part only, a new Note or Notes
of this series for the unredeemed portion hereof will be issued in the name of
the registered Holder hereof upon the cancellation hereof.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Notes may be declared,
and upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Note upon compliance by the Company with certain conditions
set forth therein. In the event the Company desires to provide for the payment
of Notes, in lieu of defeasing the Notes in accordance with the Indenture, the
Company shall either redeem an equal principal amount of 2002D Bonds or take
such action as shall be required by the 2002D Bond Indenture to defease an equal
principal amount of 2002D Bonds.

     Any amount payable by the Company in respect of principal of the Notes,
whether at maturity or prior to maturity by redemption or otherwise, in a
circumstance where there has not been a corresponding payment of principal of
2002D Bonds shall be applied simultaneously to the redemption or defeasance of
any equal principal amount of 2002D Bonds in accordance with the 2002D Bond
Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the registered Holders of not less than a majority in
aggregate principal amount of the outstanding Securities of each series affected
at the time, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or of any supplemental indenture or of
modifying in any manner the rights of the registered Holders of the Securities;
provided, however, that no such supplemental indenture shall (i) extend the
fixed maturity of any Securities of any series, or reduce the principal amount
thereof, or reduce the rate of or extend the time of payment of interest
thereon, or reduce any premium payable upon the redemption thereof, without the
consent of the registered Holder of each Security so affected or (ii) reduce the
aforesaid percentage of Securities, the registered Holders of which are required
to consent to any such supplemental indenture, without the consent of the
registered Holders of each Security then outstanding and affected thereby. The
Indenture also contains provisions permitting (i) the registered Holders of at
least 66 2/3% in aggregate principal amount of the Securities of all series at
the time outstanding affected thereby, on behalf of the registered Holders of
the Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and (ii) the registered Holders of a majority in
aggregate principal amount of the Securities of all series at the time
outstanding affected thereby, on behalf of the registered Holders of the
Securities of such series, to waive certain past defaults under the Indenture
and their consequences. Any such consent or waiver by the registered Holder of
this Note (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such registered Holder and upon all future registered Holders and
owners of this Note and of any Note issued in exchange hereof or in place

                                       24

hereof (whether by registration of transfer or otherwise), irrespective of
whether or not any notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the time and place and at the rate and in the coin or currency herein
prescribed.

     Prior to the Release Date, the Notes of this series shall be secured by a
series of Mortgage Bonds (the "Related Series of Bonds"), delivered by the
Company to the Trustee for the benefit of the Holders of the Notes. Reference is
made to the Mortgage and the Indenture for a description of the rights of the
Trustee as Holder of the Related Series of Bonds, the property mortgaged and
pledged under the Mortgage and the rights of the Company and of the Mortgage
Trustee in respect thereof, the duties and immunities of the Mortgage Trustee
and the terms and conditions upon which the Related Series of Bonds are secured
and the circumstances under which additional Mortgage Bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL BONDS, OTHER THAN (1) PLEDGED BONDS,
INCLUDING THE RELATED SERIES OF BONDS, AND (2) MORTGAGE BONDS (EXCLUSIVE OF
PLEDGED BONDS), WHICH DO NOT IN AGGREGATE PRINCIPAL AMOUNT EXCEED THE GREATER OF
FIVE PERCENT (5%) OF NET TANGIBLE ASSETS OR FIVE PERCENT (5%) OF CAPITALIZATION,
HAVE BEEN RETIRED THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE
MORTGAGE BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH
THE MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF, PROVIDED THAT NO DEFAULT
OR EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING (THE "RELEASE DATE"), THE
RELATED SERIES OF BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Security Register of the
Company, upon surrender of this Note for registration of transfer at the office
or agency of the Company in any place where the principal of and any interest on
this Note are payable or at such other offices or agencies as the Company may
designate, duly endorsed by or accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Security
Registrar or any transfer agent duly executed by the registered Holder hereof or
his or her attorney duly authorized in writing, and thereupon one or more new
Notes of this series and of like tenor, of authorized denominations and for the
same aggregate principal amount will be issued to the designated transferee or
transferees. No service charge will be made for any such transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.

     Prior to due presentment for registration of transfer of this Note, the
Company, the Trustee, any paying agent and any Note Registrar may deem and treat
the registered Holder hereof as the absolute owner hereof (whether or not this
